DETAILED DESCRIPTION
[00013] Conventionally, a frame assembly is a core structure of a two wheeled straddle type vehicle. The frame assembly supports an internal combustion engine assembly, providing the hinge points for both rear and front suspension members, which is connected to the front and rear wheel respectively, and supports a rider and any pillion or luggage. The frame assembly also supports the steering mechanism, smaller systems like a fuel tank assembly, body panels, and automotive electronics. Automotive electronics are electronic systems used in vehicles, including an engine assembly management system, a transistor-controlled ignition (TCI) unit or a capacitor discharge ignition (CDI) unit, a telematics unit, an immobilizer unit, an in-built entertainment system, and like.
[00014] The immobilizer unit is an electronic security device fitted inside a straddle type vehicle, that prevents the engine assembly from being started, unless an authorized system or key is used to access the straddle type vehicle. During an unauthorized access the immobilizer detects the malfunction and stops the fuel flow to the combustion chamber of the engine assembly, thereby providing engine assembly cut-off. Also, the immobilizer unit prevents by passing of a motor vehicle's ignition switch by means of hot wiring, thereby ensuring starting of the vehicle without key. Further, some immobilizer units also include a Radio Frequency Detection chip (RFID chip) installed within them. The immobilizer unit utilizes the RFID function for alarming the owner, which further aid in locating, monitoring and tracking the straddle type vehicle. Therefore, the immobilizer units act as a safety measure and prevents any acts of theft or unauthorized usage. Hence, it is imperative for the immobilizer unit to be located at a suitable position in the straddle type vehicle, from where the immobilizer unit can receive signal from the Global Positioning System (GPS) and send uninterrupted data to the engine assembly. Further, such identified position of the straddle type vehicle should be secured, ensuring theft proofing of the immobilizer unit.
[00015] Another type of electronic component is the TCI unit. When the transistor of the TCI unit is tuned ‘ON’, current passes through the primary side of an ignition coil (hereinafter “coil”) from the battery, to store the energy. And when the transistor is turned ‘OFF’, the current supply is stopped causing a sudden change in the current, generating high voltage on the secondary side of the coil and thus initiating ignition. When compared with the TCI unit, the CDI unit produces the spark by discharging a capacitor loaded with high voltage from the ignition coil while, however the TCI ignition charges the coil with the current before the spark is produced. Conventionally, the TCI unit is more economical as compared to the CDI unit, but the TCI unit requires more maintenance, especially when it is exposed to rain or dust.
[00016] Therefore, the TCI unit is an electric component which is used for supplying power to the internal combustion engine assembly mounted to the straddle type vehicle body. A starter relay unit aids in electric start of the engine assembly by controlling power supplied by the TCI unit, to a starter motor of the engine assembly. Therefore, it is ideally required to position the TCI unit or the CDI unit in close proximity of the ignition coil, the starter motor of the engine assembly and the starter relay unit.
[00017] Some known in the art disclose about mounting scheme for an electric component being located behind the cylinder head in the engine assembly, such that the electric component is positioned at the lower rear portion of the fuel tank assembly. Accordingly, an upper portion of the electric component is covered with the fuel tank assembly, and an obliquely lower front portion of the electric component is hidden behind the engine assembly. According to such arrangement, the electric component can be protected from dust and water. However, although such known arts disclose about providing a secured mounting arrangement of the electronic components, but lack in providing easily accessibility. This is because in such set up, the fuel tank assembly, the seating and some parts of the engine assembly assembly requires to be unassembled in order to access such electronic component. Since, electronic components such as TCI unit or CDI unit and the immobilizer unit requires frequent servicing, thereby removing multiple parts to service them, becomes cost and time intensive, and restricting ease of access of the component. for the user.
[00018] Particularly, when electronic components such as TCI unit is placed in such location as described above, transmission loss and cost increases. This is because, the starter relay is arranged behind cylinder head and inside the fuel tank assembly in a rearward position, which located at a considerable distance from the starter motor. The starter motor is installed at a lower front portion of a crankcase in an engine assembly. Thereby, a harness extending from a battery through the starter relay to the starter motor is required to be long, which increases transmission loss and costs.
[00019] Some other known arts disclose about mounting scheme of electronic components such as immobilizer unit or telematics unit, packaged under the fuel tank assembly. However, such known arts disclose about an additional support, which is taken from the recess surface of the bottom fuel tank assembly cover, for supporting the mounting of the electronic component. Although, such location provides secure placement of the component, however pose a restricted accessibility thereby difficulty in servicing of the electronic component. Besides, the electronic component requires changes in the existing fuel tank assembly by recessing an additional support member and this involves modifications of fuel tank assembly thereby, leading to an increase in cost for the user.
[00020] Thereby, it is desired to have a secured mounting location for an electronic component such as TCI unit and the immobilizer unit, such that the electronic component is closer to the engine assembly, is easier to service.
[00021] Further, the location of the electronic component should be such that, the space in which the electronic component is packaged includes free space, thereby freely enabling the electronic component in receiving and sending uninterrupted signals.
[00022] Hence, there is a need of addressing the above circumstances and problems of the known arts.

Thereby the first electronic component 201 is disposed away from heat zones of the front portion of the straddle type vehicle 10. This further increases the overall life of the first electronic component 201.
[00056] In another embodiment, the first electronic component 201 is mounted in proximity of the starter motor of engine assembly 100.
[00057] Figure 3a to Figure 3c illustrates a perspective side view of a front portion of the frame assembly 20 of a straddle type vehicle 10 in accordance with an embodiment of the present subject matter. Figure 3a illustrates a perspective view of a front portion of the frame assembly 20 with the first electronic component 201 and the ignition coil unit 202 mounted onto the frame assembly 20.
[00058] Figure 3b illustrates a perspective side view of a front portion of the frame assembly 20 without the first electronic component 201 and the ignition coil unit 202 mounted onto the frame assembly 20.
[00059] Figure 3c illustrates an exploded perspective side view of a front portion of the frame assembly 20.
[00060] As illustrated in Figure 3a and 3c, the first electronic component 201 is secured to the front portion main frame 101a, with the help of a first mounting bracket 301. The first electronic component 201 is partially enclosed within a first protective band 303. Then the first protective band 303 along with the first electronic component 201 is mounted onto the first mounting bracket 301. The first mounting bracket 301 provides rigid mounting the first electronic component 201 with the main frame 101, thereby providing protection to the first electronic component 201.
[00061] The ignition coil unit 202 is mounted onto the cross tube 108 by means of an ignition coil unit mounting bracket 302.
[00062] Figure 4 illustrates a perspective view of a first mounting bracket 301 of a frame assembly 20 in accordance with an embodiment of the present subject matter.
[00063] The first mounting bracket 301 includes two portions, i.e., a first portion 401, and a second portion 402. The first portion 401 of the first mounting bracket 301 is integrally positioned above the second portion 402 of the first mounting bracket 301. The second portion 402 is capable of being configured to run along the profile of the main frame 101 (as shown in Figure 3b). Further, the second portion 402 is connected to the main frame 101 by means of fastening means such as welding.
[00064] The first portion 401 extends inclinedly vertically upward in a bent manner, from the second portion 402, when viewed in vehicle top-down direction, such that a protruded portion ‘A’, is formed therebetween. The protruded portion ‘A’ protrudes outwardly, such that the protruded portion ‘A’ hugs at least a portion of the main frame 101, further enabling configuration of the second portion 402 to run along the profile of the main frame 101.
[00065] The first portion 401 includes a pair of first extending arms 403 on each upper end of the first portion 401. The first extending arms 403, further increases and improves surface contact of the first mounting bracket 301 with at least a portion of the main frame 101.

The relief 405 on each side of the second extending arms 404, acts as a provision to mount the protective cover 303 (as shown in Figure 3c), along with the first electronic component 201, onto the first mounting bracket 301.
[00067] Further the second extending arms 404, aid in locating the first mounting bracket 301 to main frame 101, and position the first mounting bracket 301 during welding. The second extending arms 404 ensures that the first mounting bracket 301 is firmly secured to the main frame 101 and resists any motion of the first mounting bracket 301 during assembly of the first electronic component 201.
[00068] The configuration of the first mounting bracket 301 also ensures obviation of vibration or rattling of the first mounting bracket 301 along with the first electronic component 201 during vehicle operation. Thus, the location of the first electronic component 201 and the way the first electronic component 201 is secured, helps the first electronic component 201 to perform the intended function in an efficient manner.
[00069] Further the first mounting bracket 301 also ensures the first electronic component 201 is retained in its predetermined position during its operation, preventing the unit to sag of the first electronic component 201 under gravity. And thus, preventing the foul due to being hit with the bottom portion of the fuel tank assembly 09, thereby ensuring safety and avoid undesired vibrations during vehicle use.
[00070] Because of the location of the first electronic component 201 above the cylinder head 100a and under the fuel tank assembly 09. This location ensures that the first electronic component 201 is away from heat zone and in close proximity of the ignition coil unit 202 and thereby receives undisturbed signals during the vehicle operation.
