Specification

Description:Technical Field
[0001] The present subject matter relates to hinges. More specifically, the present subject matter relates to door hinges on motor vehicles.
Background
[0002] A motor vehicle is perhaps the most popular personal transportation vehicle. It comprises of a frame which supports a prime mover and other components. These components are tightly packed within the dimensions of the vehicle and are supported by the frame. The vehicle is propelled forward by the prime mover. The prime mover can be an internal combustion (IC) engine or an electric motor or a combination thereof. The components of a motor vehicle are generally covered in body parts. Depending on the type of vehicle, a general personal transport vehicle will have a capacity to carry anywhere between one and ten people. A saddle type vehicle for example has only two wheels, and as such is inherently unstable at low speeds. These vehicles generally have a capacity for two people, a rider and a pillion. A three-wheeler vehicle on the other hand has three wheels and generally carries a driver and three passengers. A vehicle with four or more wheels can carry more passengers than a saddle type vehicle or a three-wheeler vehicle.
[0003] Safety measures such as seat belts and doors are provided on such vehicles for the protection of the driver and the passengers. A door of a vehicle is a complex assembly part that has several individual component parts working together. A vehicle door generally has a window which can be rolled up or down, disposed within the body panels of the door. A door also has a latch and a locking mechanism so that the door should not open while the vehicle is moving. Modern vehicles have doors which are equipped with electric switches that can control vehicle locking, windows, rear view mirrors etc. Naturally, a door has to be a movable part since it will be opened and closed multiple times in a day and it should not fail. A door generally opens pivotally outside from the mounting point on the vehicle frame or body. It is mounted to the vehicle with one or more hinges. Depending on the type of door, different types of hinges may be used. Most doors open horizontally forwards in a vehicle front rear direction, while some doors open vertically upwards.
[0004] Even though a vehicle door may be designed for ergonomics and comfort, it is there to serve a very important function, protection of the passengers, and as such is a vital part of any vehicle. The mounting of the door is thus of vital importance.
[0005] A major limitation associated with the manufacturing and assembly of vehicle door hinges is the non-uniformity of design of application of the door hinges. Conventional manufacturing layouts employ a different design of door hinges for the left side door in comparison to the right-side door. The manufacturing variances with door hinge design entails high investment involved in revamping manufacturing process for suiting the left side door against the right-side door, a higher component cost, a higher assembly time of the door hinge and an extended final manufacturing time of the vehicle. Original Equipment Manufacturers (OEMs) are the major stakeholders dealing with the limitations of non-uniform manufacturing variants of door hinges.
[0006] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

However, those skilled in the art will readily appreciate that the detailed descriptions given herein with respect to the figures are simply for explanatory purposes as the methods and systems may extend beyond the described embodiments. For example, the teachings presented, and the needs of a particular application may yield multiple alternative and suitable approaches to implement the functionality of any detail described herein. Therefore, any approach may extend beyond the particular implementation choices in the following embodiments described and shown.
[00029] References to “one embodiment,” “at least one embodiment,” “an embodiment,” “one example,” “an example,” “for example,” and so on indicate that the embodiment(s) or example(s) may include a particular feature, structure, characteristic, property, element, or limitation but that not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Further, repeated use of the phrase “in an embodiment” does not necessarily refer to the same embodiment.
[00030] The present invention now will be described more fully hereinafter with different embodiments. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather those embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the invention to those skilled in the art.
[00031] The present invention may be illustrated with reference to a three-wheeled vehicle or a multi-axle vehicle configured to have a vehicle door such that the features, aspects and advantages of the embodiments of the present invention is applicable to the vehicle. In an aspect, the vehicle may comprise of a prime mover being one of an internal combustion engine, an electric motor or a combination thereof or any form of prime mover capable of harnessing engine from an energy source to provide propulsion of the vehicle.
[00032] The object of the present subject matter is to provide a universal vehicle door hinge assembly having adaptability in implementation without increasing part count and component cost.
[00033] To this end, the present subject matter provides a vehicle door hinge assembly comprising of a first member, a second member and a pivoting unit. The first member is mounted on to an inner surface of a door panel of a vehicle while the second member is mounted on an external surface of a body panel of the vehicle. The pivoting unit connects the first member to the second member to provide rotational movement to the first member about a pivot axis. The first member of the vehicle door hinge assembly is designed to be symmetric about a YZ plane while the second member of the vehicle door hinge assembly is designed to be symmetric about a XY plane. The symmetric design of the first member and second member of the vehicle door hinge assembly with a pivoting unit connecting them assures the applicability of the vehicle door hinge assembly on a left hand side as well as a right hand side of the vehicle. Overall, the number of components of the vehicle door hinge assembly manufactured for a desired vehicle remains the same per assembly, further the manufacturing process only need to accommodate two types of assemblies, one where the vehicle door hinge assembly is adapted for the left hand side and other where the vehicle door hinge assembly is adapted for the right hand side.
[00034] A vehicle door is securely mounted to the vehicle body for ergonomic, aerodynamic and safety reasons. A door is a vital part of any vehicle that can have a door. The assembly of a door is usually a complex process as there are many different components that are mounted to or disposed on he door of a vehicle. For example, vehicles doors carry a window, a latch, a lock and sometimes, the rear view mirrors. The assembly of the vehicle is thus a complex process.
[00035] The hinges used to attach the door to the vehicle body is a complex part requiring a complex manufacturing process itself. Vehicle door hinges are generally made from metallic parts. The individual parts of the hinge may be stamped, forged or cast. Regardless of the design of the hinge, any vehicle door hinge will have at least two basic components, a body side mounting component and a door side mounting component. The two mounting arms may be joined by something as simple as a pivoting mechanism, or something very complex designed to give certain characteristics to the door. A hinge is usually designed with two or more mounting holes on either mounting components. Low cost vehicles generally would contain a basic pivoting hinge, whereas higher priced and luxury vehicles will have doors that open vertically, or are designed to not make any sound while being opened and closed.
[00036] In addition to being a safety feature, a door also protects the passengers from the natural elements. It is therefore vital that a locked door maintain a seal. For this, the door body itself is designed in such a way that the door can easily slot into the vehicle body to maintain a better sealing effect. For this purpose, a vehicle with more than one door may require multiple hinge designs for different doors. A hinge fitted on the top of the right hand side front door may not be of use at the top of the left hand side front door. It is often the case that hinges are specifically designed for specific joints on specific doors.
[00037] The drawback associated with the design of vehicle door assemblies is that there are no commonization of parts, and multiple different types of hinges are required. This also means that serviceability may be difficult as one hinge cannot easily replace the other, and the specific part has to be fitted. Further, the assembly and manufacture time will be longer than required. Moreover, separate assemblies have to be carried out for the different types of hinges.
[00038] In a prior art of the present subject matter, a vehicle having four doors requires to make hinges that in total are three different parts of the hinge assembly having a common body side mounting component but two different door side mounting component – where one is adapted for a left hand side vehicle door and the other is adapted for a right hand side vehicle door, thus requiring two different assemblies.
[00039] In another prior art of the present subject matter, a vehicle having four doors requires a total of eight components – wherein each body side mounting component and door side mounting component are different, and each door assembly requires at least two hinge assemblies. Further, the requirement of eight components yields to a requirement of at least four different door assemblies being required for the vehicle.
[00040] It is therefore an objective of the present subject matter to overcome the above-mentioned drawbacks and problems known in the prior arts. The present subject matter provides an improved vehicle door hinge assembly for a vehicle where the number of parts and assemblies are minimised. This increases ease of manufacturability and serviceability, and thus consists of only two symmetrical parts which can be pivotally joined together to obtain a door hinge. One part is symmetrical about the Y-Z plane, while another part is symmetrical about the X-Y plane. Thus, the same parts can be used on both left-hand side doors and right-hand side doors by rotating the first part symmetrical about YZ plane by 180 degrees.
[00041] Thus, the present subject matter has clear technical advancement over the common general knowledge and the prior art.
[00042] Further, in conventional manufacturing practices of vehicle door hinge assemblies a draft is provided on the door side mounting component and the vehicle side mounting component. The draft is configured to permit ease of interfacing of the components with the surface of the door and the vehicle body. The purpose of a manufacturing draft is to provide a form of manufacturing clearance with reference to the vehicle design.
[00043] In accordance with the present configuration to ensure ease of adaptability of the disclosed vehicle door hinge assembly, the manufacturing draft is eliminated in the first member and the second member of the vehicle door hinge assembly, instead the manufacturing draft is to be accommodated in the vehicle body and the surface of the door. Owing to customized design of the vehicle body and the vehicle door, incorporation of manufacturing variants and manufacturing drafts is easier on the vehicle body and vehicle door manufacturing side, while letting the vehicle door hinge assembly be deemed universally adaptable in all vehicle designs.
[00044] Additionally, the object of the present subject matter is to reduce the complexity involved in the manufacturing of the vehicle door assemblies.
[00045] To this end, the provision of a communized part in the form of the vehicle door hinge assembly reduces the overall number of assemblies to be undertaken in the manufacturing set-up for the manufacture of a vehicle. The vehicle door hinge assembly comprising of the similarly designed first member, second member and the pivoting unit can be transposed by 180 degrees to be adapted to suit the left-side door configuration and the right side door configuration, reducing the total number of assemblies to merely two. Thus, the complexity in assembly of the vehicle door hinge assembly in the vehicle is significantly reduced along with the manufacturing time spent on the development of the individual components of the vehicle door hinge assembly.
[00046] Further, an additional cost of investment for manufacture of a newly designed part is entirely eliminated in accordance with the disclosed configuration of a universal vehicle door hinge assembly.
[00047] Ancillary to reduced assembly time and manufacturing time, the object of the present subject matter is to reduce the cost associated with assembly and manufacturing.
[00048] In a shop floor set-up the cost associated with assembly and manufacturing are counted in terms of man hours spent in completing the task of manufacturing and assembly. With an improved and communized vehicle door hinge assembly design, the assembly time and manufacturing time is reduced and consequently the cost of manufacture and assembly is reduced.
[00049] The object of the present subject matter is to provide an economic replacement to vehicle hinge door assemblies known in conventional vehicle layouts.
[00050] In accordance with the present configuration, the vehicle door hinge assembly additionally reduces the overall cost of the components developed for the vehicle door hinge assembly.
[00051] Additionally, the present subject matter in accordance with the disclosed configuration proffers a vehicle door hinge assembly having improved packaging effectiveness.
[00052] In accordance with the present configuration, the provision of a simple vehicle door hinge assembly design comprising of symmetrical first member and symmetrical second member connected by a pivoting unit allows adaptability of the vehicle door hinge assembly in a compact vehicle layout and provide improved packaging efficiency in comparison to conventional known vehicle door hinge assemblies.
