[0033] The embodiments of the present application provide an automobile. It should be noted that the automobile in the present application may refer to large automobiles, small automobiles, special-purpose automobiles, etc. Exemplarily, classified by vehicle type, the automobile in the present application may be a sedan vehicle type, an off-road vehicle type, a multi-purpose vehicle (MPV) type or other vehicle types. For an automobile, generally, a range extender 50 and a subframe 40 are provided. The range extender 50 belongs to a type of internal combustion engine. The range extender 50 is the main power device for providing driving electric energy for a range-extended electric vehicle. The range extender 50 uses a mixture of gasoline and air, releases a huge amount of energy during the combustion process, and converts this part of the energy into electric energy for the movement of new energy vehicles; while the subframe 40 is mainly used to support the front and rear axles and suspension systems of the automobile.

[0034] On this basis, with reference to Figure 1 - Figure 2 , the embodiments of the present application provide an assembly tooling 10 for an automobile range extender. The assembly tooling 10 for an automobile range extender includes a first tray 1 and a second tray 2. The second tray 2 surrounds the first tray 1 in the circumferential direction. The second tray 2 is connected to the first tray 1 through a detachable structure 3. The first tray 1 is used to support the range extender 50, and the second tray 2 is used to support the subframe 40.

[0035] In the related art, when the range extender 50 and the subframe 40 are assembled together, due to the assembly error generated at the assembly boundary between the range extender 50 and the subframe 40 and the vehicle frame, the assembly is difficult, and the assembly efficiency is also low.

[0036] In this application, the automotive range extender assembly tooling 10 is set as a first tray 1 and a second tray 2 that are detachably connected. The second tray 2 surrounds the first tray 1 in the circumferential direction. The first tray 1 is used to support the range extender 50, and the second tray 2 is used to support the subframe 40. That is, when assembled to the vehicle frame, the subframe 40 surrounds the outer peripheral side of the range extender 50. The subframe 40 is provided with the suspension system of the vehicle, avoiding the vibration generated during the operation of the range extender 50 from being transmitted to the interior of the vehicle and causing vibration effects on the vehicle occupants.

[0037] The first tray 1 and the second tray 2 are connected by a detachable structure 3. By installing the range extender 50 and the subframe 40 onto the first tray 1 and the second tray 2 respectively, the process production line for installing the vehicle can be reduced, thereby reducing the installation cost of the vehicle. To avoid the error when the range extender 50 and the subframe 40 are assembled onto the vehicle frame, during the process of installing the range extender 50 and the subframe 40 onto the vehicle frame, the detachable structure 3 is removed, and the first tray 1 and the second tray 2 are separated, making the movements of the range extender 50 and the subframe 40 relatively independent. The range extender 50 and the subframe 40 can be installed sequentially to reduce the assembly difficulty problem during the co-assembly of the range extender 50 and the subframe 40, making the installation of the range extender 50 and the subframe 40 simple and convenient, and reducing the cost.

[0038] For example, the first tray 1 can be rectangular, and the second tray is a rectangular frame surrounding the outer peripheral side of the first tray 1.

[0039] For example, the detachable structure 3 can include a fixing block 31. The fixing block 31 can be detachably connected to the first tray 1 and the second tray 2 respectively by fasteners 32; alternatively, the first tray 1 and the second tray 2 are provided with openings, and a buckle can be passed through the two openings and fixed with bolts.

[0040] The automotive range extender assembly tooling 10 provided by the embodiment of this application includes a first tray 1 and a second tray 2 surrounding the outer peripheral side of the first tray 1. The first tray 1 is used to support the range extender 50, and the second tray 2 is used to support the subframe 40. The second tray 2 is connected to the first tray 1 by a detachable structure 3. By installing the range extender 50 and the subframe 40 onto the first tray 1 and the second tray 2 respectively, the process production line for installing the vehicle can be reduced, thereby reducing the installation cost of the vehicle; when assembling the range extender 50 and the subframe 40 onto the vehicle, the first tray 1 and the second tray 2 are separated, making the movements of the range extender 50 and the subframe 40 relatively independent. The range extender 50 and the subframe 40 can be installed independently to improve the accuracy when the range extender 50 and the subframe 40 are assembled onto the vehicle, reduce the assembly difficulty problem during the co-assembly of the range extender 50 and the subframe 40, make the installation of the range extender 50 and the subframe 40 simple and convenient, and improve the assembly efficiency.

The fixing block 31 is fixedly connected to the first tray 1, or the first tray 1 and the fixing block 31 can be integrally processed and formed, and the fixing block 31 extends in the direction towards the second tray 2. The fastener 32 cooperates with the fixing block 31 to fixedly connect the first tray 1 and the second tray 2, which can make the fixing and detaching methods between the first tray 1 and the second tray 2 simple and improve the firmness of the connection between the first tray 1 and the second tray 2.

[0042] In a specific example, the fixing block 31 has a first mounting hole with internal threads therein. The fastener 32 is fixed on the second tray 2 and has external threads. The fastener 32 can pass through the first mounting hole and be threadedly connected to the first mounting hole; alternatively, the fastener 32 includes a bolt and a nut, the bolt is fixed on the second tray 2, and the bolt passes through the first mounting hole and is fixedly connected to the nut; or the fastener 32 includes a bolt and a nut, the second tray 2 has a second mounting hole opposite to the first mounting hole, and the bolt passes through the first mounting hole and the second mounting hole and is fixedly connected to the nut.

[0043] , in some embodiments of the present application, the detachable structure 3 includes a fixing block 31 and a fastener 32.

The fixing block 31 is fixedly connected to the second tray 2, or the second tray 2 and the fixing block 31 can be integrally processed and formed, and the fixing block 31 extends in the direction towards the first tray 1. The fastener 32 cooperates with the fixing block 31 to fixedly connect the first tray 1 and the second tray 2, which can make the fixing and detaching methods between the first tray 1 and the second tray 2 simple and improve the firmness of the connection between the first tray 1 and the second tray 2.

[0044] In a specific example, the fixing block 31 has a first mounting hole with internal threads therein. The fastener 32 is fixed on the first tray 1 and has external threads. The fastener 32 can pass through the first mounting hole and be threadedly connected to the first mounting hole; alternatively, the fastener 32 includes a bolt and a nut, the bolt is fixed on the first tray 1, and the bolt passes through the first mounting hole and is fixedly connected to the nut; or the fastener 32 includes a bolt and a nut, the first tray 1 has a second mounting hole opposite to the first mounting hole, and the bolt passes through the first mounting hole and the second mounting hole and is fixedly connected to the nut.

[0046] Referring to Figure 1 , in some embodiments of the present application, the first tray 1 and the second tray 2 are spaced apart along the circumferential direction of the first tray 1. In the horizontal direction of the first tray 1 and the second tray 2, there is a gap between the first tray 1 and the second tray 2, which facilitates the independent movement between the first tray 1 and the second tray 2 when they are separated, and also makes it easy to generate independent movement between the range extender 50 and the subframe 40.

[0047] Referring to Figure 1 , in some embodiments of the present application, the first tray 1 is provided with a first positioning post 11, and the first positioning post 11 is in positioning cooperation with the range extender 50.
