Description:FIELD OF THE INVENTION

[0001] The present invention generally relates to a saddle-type vehicle and more particularly, to a battery pack mounting structure for a saddle-type vehicle.
BACKGROUND

[0002] In a saddle-type vehicle, for example, the dynamic and static performance of the battery mounting unit is closely related to the safety of the whole vehicle. The ride handling, and dynamic characteristics are a major differentiating factor for various saddle-type vehicles, which are considered by users, as per their riding styles. The change in stiffness of the saddle type vehicle as per the vehicle category or as per the rider’s riding style is an important factor for stiffness and strength of the vehicle. The battery and its mounting are a major structural component which plays a major role in stiffness of the vehicle.
[0003] The problem in the existing state of the art is that the battery is directly bolted onto the frame of the vehicle. In an example scenario, when the battery is directly bolted onto the frame structure, and when there is a need to replace the battery with another battery (high or low power battery, for example) and attach it to the same frame, it is not possible to replace the battery without having to alter the frame structure to accommodate the corresponding battery.
[0004] The existing solutions include using battery as a structural member. By using battery as a structural member, the battery is linked to the stiffness of the frame and the vehicle. However, mounting different sized batteries to the same frame poses a challenge on the stiffness of the frame and thereby on the vehicle.
SUMMARY

This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.
[0006] The main objective of the present disclosure is to provide a battery pack mounting structure for a saddle-type vehicle.
[0007] The inventors of the present invention have realized that it is possible to change the battery mounting arrangement to change the stiffness.
[0008] In an embodiment of the present disclosure, a frame structure for a saddle-type vehicle is disclosed. The frame structure includes a pair of main tubes arranged in a fork configuration. Each main tube includes a front portion, a mid-horizontal portion, and a rear portion. The frame structure includes a front cross tube coupled to the respective front portions of the pair of main tubes. The frame structure includes a swing arm pivot assembly coupled to the respective rear portions of the pair of main tubes.

[00027] Embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings.
[00028] An Electric Vehicle (EV) or a battery powered vehicle including, and not limited to two-wheelers such as scooters, mopeds, motorbikes/motorcycles; three-wheelers such as auto-rickshaws, four-wheelers such as cars and other Light Commercial Vehicles (LCVs) and Heavy Commercial Vehicles (HCVs) primarily work on the principle of driving an electric motor using power from the batteries provided in the EV. Furthermore, the electric vehicle may have at least one wheel which is electrically powered to traverse such a vehicle. The term ‘wheel’ may refer to any ground-engaging member which allows traversal of the electric vehicle over a path. The types of EVs include Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV) and Range Extended Electric Vehicle. However, the subsequent paragraphs pertain to the different elements of a Battery Electric Vehicle (BEV).
[00029] Figure 1 illustrates an exemplary electric vehicle, and the vehicle’s charging and other infrastructure. In construction, the electric vehicle (EV) 100 typically comprises a battery or battery pack 105 enclosed within a battery casing and includes a Battery Management System (BMS), an on-board charger 110, a Motor Controller Unit (MCU), an electric motor 115 and an electric transmission system 120. The primary functions of the above-mentioned elements are detailed in the following paragraphs: The battery of an EV 100 (also known as Electric Vehicle Battery (EVB) or traction battery) is re-chargeable in nature and is the primary source of energy required for the operation of the EV, wherein the battery 105 is typically charged using the electric power from the grid through a charging infrastructure 125. The battery may be charged using Alternating Current (AC) or Direct Current (DC), wherein, in case of AC input, the on-board charger 110 converts the AC power to DC power after which the DC power is transmitted to the battery through the BMS. However, in case of DC charging, the on-board charger 110 may be bypassed, and the current transmitted directly to the battery through the BMS. Additionally, the EV 100 may also be equipped with wireless infrastructure such as, but not limited to Bluetooth, Wi-Fi and so on to facilitate wireless communication with the charging infrastructure 125, other EVs or the cloud.
[00030] The battery 105 is made up of a plurality of cells which are grouped into a plurality of modules in a manner in which the temperature difference between the cells does not exceed 5 °C. The terms “battery”, and “battery pack” may be used interchangeably and may refer to any of a variety of different rechargeable cell compositions and configurations including, but not limited to, lithium-ion (e.g., lithium iron phosphate, lithium cobalt oxide, other lithium metal oxides, etc.), lithium-ion polymer, nickel metal hydride, nickel cadmium, nickel hydrogen, nickel-zinc, silver zinc, or other battery types or configurations. The term “battery pack” as used herein may refer to multiple individual batteries enclosed within a single structure or multi-piece structure. The individual batteries may be electrically interconnected to achieve a desired voltage and current capacity for a desired application. The Battery Management System (BMS) is an electronic system, the primary function of which is to ensure that the battery 105 is operating safely and efficiently. The BMS continuously monitors different parameters of the battery such as temperature, voltage, current and so on, and communicates these parameters to the Electronic Control Unit (ECU) and the Motor Controller Unit (MCU) in the EV using one or more protocols including but not limited to, Controller Area Network (CAN) bus protocol which facilitates the communication between the ECU and MCU and other peripheral elements of the EV 110 without the requirement of a host computer.
[00031] The MCU primarily controls or regulates the operation of the electric motor based on the power transmitted from the vehicle’s battery, wherein the primary functions of the MCU include starting the electric motor 115, stopping the electric motor 115, controlling the speed of the electric motor 115, enabling the vehicle to move in the reverse direction and protect the electric motor 115 from premature wear and tear. The primary function of the electric motor 115 is to convert electrical energy into mechanical energy, wherein the converted mechanical energy is subsequently transferred to the transmission system of the EV to facilitate movement of the EV. Additionally, the electric motor 115 also acts as a generator during regenerative braking (that is, kinetic energy of the EV in motion is converted into electrical energy and stored in the battery of the EV). The types of motors generally employed in EVs include, but are not limited to DC series motor, Brushless DC motor (also known as BLDC motors), Permanent Magnet Synchronous Motor (PMSM), Three Phase AC Induction Motors and Switched Reluctance Motor (SRM).
[00032] The transmission system 120 of the EV 100 facilitates the transfer of the generated mechanical energy by the electric motor 115 to the wheels (130a, 130b) of the EV. Generally, the transmission systems 120 used in EVs include single speed transmission system and multi-speed (i.e., two-speed) transmission system, wherein the single speed transmission system comprises a single gear pair whereby the EV runs at a constant speed ratio between the motor rotational speed and the wheel rotational speed. However, the multi-speed/two-speed transmission system comprises a compound planetary gear system with a double pinion planetary gear set and a single pinion planetary gear set thereby resulting in two different gear ratios which facilitates higher torque and vehicle speed depending on the selected gear ratio.
[00033] In one embodiment, all data pertaining to the EV 100 or charging infrastructure 125 or both, are collected and processed using a remote server (known as cloud) 135, wherein the processed data is indicated to the rider of the EV 100 through a display unit present in the dashboard 140 of the EV 100. In an embodiment, the display unit may be an interactive or touch sensitive display unit. In another embodiment, the display unit may be a non-interactive display unit.
[00034] Figure 2 illustrates a perspective view of a frame structure (200) of a saddle-type vehicle, according to an embodiment of the present disclosure. The frame structure (200) includes a pair of main tubes (205a, 205b) coupled to a head tube (210) and arranged in a fork configuration. The pair of main tubes (205a, 205b) can also be considered to be arranged in an inverted “V” configuration. The pair of main tubes (205a, 205b) is interchangeably referred to as main tube (205) in the present disclosure.
[00035] Referring to Figure 2, the frame structure (200) includes a pair of side tubes (215a, 215b). Each side tube (215a, 215b) includes a front end (220a, 220b) and a rear end (225a, 225b) coupled respectively to the front portion (AA’-BB’) and the rear portion (CC’-DD') of the corresponding main tube (205a, 205b). The front portion (AA’-BB’) and the rear portion (CC’-DD') of the corresponding main tube (205a, 205b) is shown in Figure 3.
[00036] Referring to Figure 3, the frame structure (200) includes a first cross tube, i.e., a front cross tube (305) coupled to the respective front portions (AA’- BB’) of the pair of main tubes (205a, 205b). The front cross tube (305) is also referred to as front battery cross tube. The front cross tube (305) is welded to the pair of main tubes (205a, 205b). The functionality of the front cross tube (305) or the front battery cross tube is to mount battery from front. Further, the front cross tube (305) adds stiffness to the frame structure (200).
[00037] The frame structure (200) includes a second cross tube, i.e., a mid-cross tube (310). The mid-cross tube (310) is coupled to the respective rear portion (CC’- DD') of the pair of main tubes (205a, 205b). The second cross tube or the mid-cross tube is also referred to as swing arm pivot cross tube. The mid-cross tube (310) is welded on the swing arm pivot mounts. The swing art pivot assembly is further explained in conjunction with Figure 4. The functionality of the mid-cross tube (310) is mounting the rear battery mounts and adding stiffness to the frame structure (200).
[00038] It is to be noted that each side tube (215) is substantially parallel to the mid-horizonal portion of the corresponding main tube in order to maximize the battery volume. The side tubes (215a, 215b) are welded to the main tubes (205a, 205b). The functionality of the side tubes is to add stiffness, majorly vertical stiffness, to the whole frame structure (200). Further, it provides strength for the side stand load cases. Furthermore, it is used for floorboard battery mounting.
[00039] One of the crucial components of a saddle type vehicle is the swing arm pivot assembly (405) of a swing arm assembly connected to the frame. The swing arm acts as a load transfer linkage between rear wheel and the frame through a rear shock absorber. Figure 4 illustrates the swing arm assembly. The frame structure (200) includes the swing arm pivot assembly (405) coupled to the respective rear portions of the pair of main tubes (305a, 305b). The swing arm pivot assembly (405) includes a pair of swing arm pivot gussets (410a, 410b) connected to each other through a swing arm pivot cross tube (415).
[00040] It is to be noted that the mid-cross tube (310) of Figure 3 and the swing arm pivot cross tube (415) of Figure 4 are same and have been interchangeably referred to in the present disclosure. The swing arm pivot assembly (405) is formed with sheet metal components which are welded together to form a sub assembly having a plurality of parts. The sub assembly is then welded on the respective rear portions of the pair of main tubes (205a, 205b).
[00041] Figure 5 illustrates a bottom view of a battery pack mounting structure (500) in the frame structure (200), according to an embodiment of the present disclosure.
[00042] Referring to Figure 5, a pair of front battery mounting brackets (502) are coupled, using fasteners (508A), to the front cross tube (305) and the mid-horizontal portion (BB’- CC’) of the pair of main tubes (205a, 205b). A pair of rear battery mounting brackets (504) are coupled, using fasteners (508B) to the pivot cross tube (415).
[00043] A battery (525) is mounted, using fasteners (not shown), on to the pair of front battery mounting brackets (502) and the pair of rear battery mounting brackets (504). In an embodiment, the pair of front battery mounting brackets (502) are substantially L-shaped. The first end of each front battery mounting brackets (502) are coupled, using the fasteners (508A), to the bottom of the front cross tube (305) and a second end of each front battery mounting brackets (502) are coupled, using the fasteners (508A), to the sides of the main tubes (205a, 205b). In one embodiment, the mounting brackets (504) are welded to the tubes (205a, 205b) and not just fastened, using fasteners. The battery (525) is mounted to the pair of front battery mounting brackets (502) at a front connecting point (510). The front connecting point (510) is disposed on the L-shaped front battery mounting brackets (502) between the first end and the second end. In an embodiment, the battery (525) shown in Figure 5 is similar to the battery (105) shown in Figure 1.
[00044] Referring to Figure 5, the frame structure (200) includes a pair of clamp brackets (506) attached to the pivot cross tube (415). Each of the clamp brackets (506) is configured to receive the second end of each rear battery mounting brackets (504).
[00045] The pair of rear battery mounting brackets (504) are substantially L-shaped. An end of a longer arm of each of the substantially L-shaped rear battery mounting brackets (504) are coupled, using fasteners (508B), to the pivot cross tube (415). An end of a shorter arm is coupled, using the fasteners (508B), to clamp brackets (506) extending from the pivot cross tube (415), to receive the end of the shorter arm of the rear battery mounting bracket (504), on the outer surface of the pivot cross tube (415).
[00046] In an embodiment, both the ends of the substantially L-shaped rear battery mounting brackets (504) are coupled to the pivot cross tube (415).
[00047] In an embodiment, the battery (525) is mounted to the rear battery mounting brackets (504) at a rear connecting point (512), wherein the rear connecting point (512) is disposed on the L-shaped rear battery mounting brackets (504) between the ends of the L-shaped arms of the rear battery mounting brackets (504).
[00048] In an alternate embodiment, the first end of each rear battery mounting brackets (504) are coupled, using the fasteners (508B), to the bottom of the pivot cross tube (415) and the second end of each rear battery mounting brackets (504) are coupled, using the fasteners (508B), to the battery (525).
[00049] In yet another alternate embodiment, the first end of each rear battery mounting brackets (504) are coupled, using the fasteners (508B), to the clamp brackets (506) extending from the pivot cross tube (415) and the second end of each rear battery mounting brackets (504) are coupled, using the fasteners (508B), to the battery (525).
[00050] Thus, based on the stiffness and battery size requirements, without changing the frame structure (200) of the saddle-type vehicle (10), the ends of the rear battery mounting brackets (504) are connected to the pivot cross tube (415), thereby allowing the battery (525) to be mounted onto the rear battery mounting brackets (504); or attaching one end of the rear battery mounting brackets (504) directly to the battery (525) and the other end of the rear battery mounting brackets (504) to the frame structure (200).
[00051] Figure 6 illustrates an isometric view (600) of the frame structure (200) where the battery (525) is bolted to the battery mounting brackets (502, 504), according to an embodiment of the present disclosure.
[00052] The battery (525) is bolted to the battery mounting brackets (502, 504) and these battery mounting brackets (502, 504) are bolted on the frame (200) with load paths between the frame (200) and the battery (525).
[00053] In an embodiment, the frame (200) includes front clamp brackets (606) attached to the side tube (215a, 215b) and the main tube (205a, 205b). The front battery mounting bracket (502) is fixed to the front clamp bracket (606) in the region (602) as shown in Figure 6. The front clamp brackets (606) extend from each of the side tube (215a, 215b) to the corresponding main tube (205a, 205b), wherein each of the front clamp brackets (606) is configured to receive the second end of the front battery mounting brackets (502). In an embodiment, one end of the L-shaped front battery mounting brackets (502) is coupled to the front cross tube (305) and the other end is coupled to the sides of the main tubes (205a, 205b) through the front clamp brackets (606) as shown in Figure 6. Similarly, one end of the rear battery mounting brackets (504) is coupled to the pivot cross tube (415) through the clamp brackets (506) as shown in Figure 5.
[00054] In an embodiment, the battery (525) is mounted to the front battery mounting brackets (502) at a front connecting point (510), wherein the front connecting point (510) is disposed on the L-shaped front battery mounting brackets (502) between the ends of the L-shaped arms of the front battery mounting brackets (502).
[00055] In an alternate embodiment, the first end of each front battery mounting brackets (502) are coupled, using the fasteners (508A), to the bottom of the front cross tube (305) and the second end of each front battery mounting brackets (502) are coupled, using the fasteners (508A), to the battery (525).
[00056] In an alternate embodiment, the battery (525) is mounted, using the fasteners (508A), to the first end of each front battery mounting brackets (502) and the second end of each front battery mounting brackets (502) are coupled, using the fasteners (508A), either to the sides of the main tubes (205a, 205b) or the front clamp brackets (606).
[00057] Thus, based on the stiffness and battery size requirements, without changing the frame structure (200) of the saddle-type vehicle (10), the ends of the front battery mounting brackets (502) is be connected to the frame structure (200), thereby allowing the battery (525) to be mounted onto the front battery mounting brackets (502) or attaching one end of the front battery mounting brackets (502) directly to the battery (525) and the other end of the front battery mounting brackets (502) to the frame structure (200).
[00058] Since the battery (525) is a cuboidal hollow structure, the section increases the stiffness of the bottom frame of the vehicle (100). In the disclosed battery mounting structure (500), the length of the battery mounting brackets (502, 504) only needs to be changed to accommodate batteries (525) of different dimension without having to change the structure of the frame (200). This design of the battery mounting brackets (502, 504) implemented herein are configured to change the overall stiffness of the frame (200), thereby changing vehicle dynamics of the vehicle (100) as per the specifications. The disclosed frame structure (200) along with the battery pack mounting structure (500) is configured to change the vehicle stiffness without change in the battery frame or the vehicle layout, leading to smaller timelines, lower cost to create a differentiating factor between vehicles. With these battery mounting brackets (502, 504) the vehicle is independent of the battery stiffness.
[00059] Figure 7 illustrates isometric view (700) of the frame structure (200) known in the state of the art, where the battery is bolted at the four shown axes (712) to the frame (200), according to an embodiment of the present disclosure. In this case, as the battery (525) is directly mounted on the frame (200) of the vehicle, different sized batteries cannot be accommodated without changing the frame of the vehicle.
[00060] Figure 8 illustrates the experimental results showing the increase in the stiffness of the frame structure by changing the mounting of the battery to the frame (200) and the mounting brackets (502, 504). In particular, Figure 8 illustrates experimental results showing the increase in the stiffness of the frame by 22.5% in the lateral direction, according to an embodiment of the present disclosure. Referring to Figure 8, it is observed that, there is the difference in the displacement result between the mounting of battery (525) to the frame structure (200) and the battery mounting brackets (502, 504) using bolts which is the right side image (800B) and the mounting of the battery (525) only to the battery mounting brackets (502, 504) which is shown in left side image 800A.
[00061] Furthermore, embodiments of the disclosed devices and systems may be readily implemented, fully or partially, in software using, for example, object or object-oriented software development environments that provide portable source code that can be used on a variety of computer platforms. Alternatively, embodiments of the disclosed methods, processes, modules, devices, systems, and computer program product can be implemented partially or fully in hardware using, for example, standard logic circuits or a very-large-scale integration (VLSI) design. Other hardware or software can be used to implement embodiments depending on the speed and/or efficiency requirements of the systems, the particular function, and/or particular software or hardware system, microprocessor, or microcomputer being utilized.
[00062] In this application, unless specifically stated otherwise, the use of the singular includes the plural and the use of “or” means “and/or.” Furthermore, use of the terms “including” or “having” is not limiting. Any range described herein will be understood to include the endpoints and all values between the endpoints.
