DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0022] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular alternative embodiment or set of alternative embodiments. It will be explicitly understood that the embodiments described herein can be combined with other embodiments.

[0023] The auxiliary frame assembly and the vehicle provided by the present application will be described in detail below in combination with the embodiments.

[0024] Please refer to Figures 1 to 3 , Figure 1 is an exploded schematic view of an embodiment of the auxiliary frame assembly of the present application; Figure 2 is a partial structural schematic view of an embodiment of the auxiliary frame of the present application; Figure 3is a structural schematic diagram of an embodiment of the bracket. The present application provides a subframe assembly 100 for mounting to a vehicle body (not shown in the figure), the vehicle body having a connecting hole (not shown in the figure). The subframe assembly 100 comprises a subframe 1, a bracket 2, a sleeve 4 and a connecting piece 3. The subframe 1 is provided with a first through hole 12. The bracket 2 is provided with a second through hole 22. The sleeve 4 is arranged between the subframe 1 and the bracket 2, and the sleeve 4 is provided with a third through hole 41. The first through hole 12, the second through hole 22 and the third through hole 41 can be coaxially arranged. The connecting piece 3 passes through the first through hole 12, the second through hole 22 and the third through hole 41 and is connected to the connecting hole. That is, the connecting piece 3 can pass through the bracket 2, the sleeve 4 and the subframe 1 in sequence and then be connected to the connecting hole. The connecting piece 3 abuts the subframe 1 against the vehicle body.

[0025] Among them, one of the bracket 2 or the subframe 1 is provided with a first limiting portion 21 corresponding to the outer peripheral position of the sleeve 4, and the other is provided with a second limiting portion 11 corresponding to the outer peripheral position of the sleeve 4. Corresponding to the outer peripheral position of the sleeve 4 means that the first limiting portion 21 can be roughly just fitted to the outer peripheral position of the sleeve 4. The first limiting portion 21 cooperates with the second limiting portion 11 to limit the relative movement of the bracket 2 and the subframe 1 along the circumferential direction of the sleeve 4. The distance from the first limiting portion 21 to the axis of the sleeve 4 is greater than or equal to the outer radius of the sleeve 4. That is, the sleeve 4 is installed on the inner side of the first limiting portion 21 towards the axis.

[0026] Through the above arrangement, when the connecting piece 3 is installed, under the action of the first limiting portion 21 and the second limiting portion 11, the relative movement of the bracket 2 along the circumferential direction of the sleeve 4 is limited, and the positioning size of the bracket 2 is not easy to deviate. And the first limiting portion 21 and the second limiting portion 11 are located at the outer periphery of the sleeve 4, when the connecting piece 3 transmits a larger torque to the bracket 2 or the subframe 1, the first limiting portion 21 can be supported on the outer periphery of the sleeve 4 and is not easy to deform, improving the reliability of the assembly of the bracket 2 and the assembly precision.

[0027] The distribution mode of the first limiting portion 21 and the second limiting portion 11 can be set according to actual conditions, which is not limited here. For example, the first limiting portion 21 can be arranged on the bracket 2, and the second limiting portion 11 can be arranged on the subframe 1. For example, the first limiting portion 21 can be arranged on the subframe 1, and the second limiting portion 11 can be arranged on the bracket 2. The number of the first limiting portion 21 and the second limiting portion 11 can also be set according to actual conditions, for example, the first limiting portion 21 and the second limiting portion 11 can be equally spaced by two, three, four or the like along the circumferential direction of the sleeve 4.

[0028] The specific structure of the first limiting part 21 and the second limiting part 11 can be set according to actual conditions, and the relative movement of the support 2 and the auxiliary frame 1 along the circumference of the sleeve 4 can be realized. For example, the first limiting part 21 and the second limiting part 11 can be a buckle structure that buckles each other. Alternatively, the first limiting part 21 and the second limiting part 11 can be protrusions that protrude from each other's surface, and the two protrusions interfere with each other when the support 2 rotates. The connecting piece 3 can be a bolt, a screw, etc., which can pass through the support 2, the sleeve 4, the auxiliary frame 1 and be fixed to the vehicle body, and is not limited here.

[0029] In an embodiment, the first limiting part 21 protrudes from the support 2. The first limiting part 21 extends in the direction of the auxiliary frame 1 along the support 2 and protrudes. The second limiting part 11 is a limiting groove 111. The limiting groove 111 is recessed in the direction of the auxiliary frame 1 along the support 2. The limiting groove 111 communicates with the first through hole 12. The sleeve 4 is arranged in the first through hole 12. The first limiting part 21 is embedded in the limiting groove 111 and abuts the outer circumferential surface of the sleeve 4. That is, along the radial direction of the sleeve 4, the outer side of the first limiting part 21 away from the axis of the sleeve 4 can abut the inner wall of the limiting groove 111 away from the axis of the sleeve 4. The inner side of the first limiting part 21 close to the axis of the sleeve 4 abuts the outer circumference of the sleeve 4.

[0030] Through the above arrangement, when the support 2 is assembled, the first limiting part 21 can be directly inserted into the limiting groove 111, the positioning can be simply and quickly completed, and good assembly limiting effect is achieved. Embedding the first limiting part 21 in the limiting groove 111 can also not interfere with the abutment between the support 2 and the auxiliary frame 1, and the support 2 can be closely abutted to the auxiliary frame 1, and the assembly is compact.

[0031] Please refer to Figure 4 , Figure 4 is a cross-sectional view of an embodiment of the auxiliary frame assembly of the present application. In an embodiment, the first through hole 12 includes a first hole section 121 and a second hole section 122 coaxially connected. The inner diameter of the first hole section 121 is greater than or equal to the outer diameter of the sleeve 4. The inner diameter of the second hole section 122 is smaller than the outer diameter of the sleeve 4. The first through hole 12 is in the form of a stepped hole. The sleeve 4 is coaxially arranged in the first hole section 121. The sleeve 4 can be mounted on the stepped surface formed at the intersection of the first hole section 121 and the second hole section 122.

[0032] Through the above arrangement, the sleeve 4 is contained in the first hole section 121, the space inside the auxiliary frame 1 is reasonably utilized, the interference of the sleeve 4 on the assembly between the support 2 and the auxiliary frame 1 can be reduced, and the auxiliary frame assembly 100 is compactly assembled.

[0033] In an embodiment, the limiting groove 111 is communicated with the first hole section 121. In the extending direction of the axis, the depth of the limiting groove 111 is equal to the depth of the first hole section 121. Through the above arrangement, the first limiting part 21 has an increased contact area with the sleeve 4, and the sleeve 4 can provide better support for the first limiting part 21, and the sub-frame assembly 100 is stable in assembly.

[0034] Further, in an embodiment, in the direction of the axis, the length of the sleeve 4 is equal to the depth of the first hole section 121. That is, one end of the sleeve 4 is attached to the step surface formed by the intersection of the first hole section 121 and the second hole section 122, and the other end is flush with the opening of the first hole section 121. Through the above arrangement, in the extending direction of the axis, the first limiting part 21 in the limiting groove 111 can be in contact with the sleeve 4 everywhere, and the sleeve 4 can more comprehensively support the first limiting part 21, and the first limiting part 21 is not easy to deform to cause the sub-frame assembly 100 to be assembled poorly.

[0035] In an embodiment, in the extending direction, the length of the first limiting part 21 is less than the depth of the limiting groove 111. Thus, when the bracket 2 is mounted to the sub-frame 1, the first limiting part 21 can be completely inserted into the limiting groove 111, and the bracket 2 and the sub-frame 1 are not easy to interfere and cannot be closely attached when the bracket 2 is assembled with the sub-frame 1 due to the first limiting part 21 not being completely inserted into the limiting groove 111, and the sub-frame assembly 100 is compact in structure.

[0036] In an embodiment, the bracket 2 includes a first bracket 23 and a second bracket 24. The first bracket 23 is provided with the first limiting part 21 and the second through hole 22 at one end. The connecting piece 3 fixes the first bracket 23 to the sub-frame 1. The other end of the first bracket 23 is connected to the second bracket 24. The first bracket 23 and the second bracket 24 can be connected in a head-to-tail manner. The second bracket 24 is used to be fixed with a battery.

[0037] When the first bracket 23 and the second bracket 24 are assembled, the first bracket 23 can be assembled and fixed with the sub-frame 1 first, then the second bracket 24 is assembled and fixed with other structures such as a battery, and finally the first bracket 23 and the second bracket 24 are connected to each other to complete the assembly.

[0038] Through the above arrangement, compared with the overall installation of the bracket 2, the first bracket 23 and the second bracket 24 can be distributed and assembled, that is, a more flexible assembly process is provided, and the assembly difficulty is reduced. The first bracket 23 and the second bracket 24 can be assembled to corresponding structures such as the sub-frame 1 and the battery respectively, and then connected to each other, which is also conducive to timely discovery and adjustment when an assembly error occurs, and the sub-frame assembly 100 is accurately and conveniently assembled.

[0039] In an embodiment, the first bracket 23 comprises a first mounting portion 231 and a first bent portion 232. The first mounting portion 231 and the first bent portion 232 can have an included angle therebetween, for example, the first mounting portion 231 and the first bent portion 232 can be arranged perpendicularly. The first mounting portion 231 is provided with the first limiting portion 21 and the second through hole 22. The second bracket 24 comprises a second mounting portion 241 and a second bent portion 242. The second mounting portion 241 and the second bent portion 242 can also have an included angle therebetween, for example, the second mounting portion 241 and the second bent portion 242 can be arranged perpendicularly. The second mounting portion 241 is used to be fixed with a structure such as a battery. The first bent portion 232 is parallel to the second bent portion 242. The first bent portion 232 is provided with a plurality of mounting holes 2321. The second bent portion 242 is provided with a plurality of mounting members 2421. Each mounting member 2421 is fixed to a mounting hole 2321.

[0040] Through the above arrangement, when the first bracket 23 and the second bracket 24 are assembled, it can be directly observed whether they are parallel or each mounting member 2421 can be aligned with the mounting hole 2321, so as to know whether the assembly size of the first bracket 23 and the second bracket 24 is accurate, and the sub-frame assembly 100 is convenient to assemble. Moreover, the first mounting portion 231 and the second mounting portion 241 can be operated without affecting each other during installation, and after being respectively installed, the first bent portion 232 and the second bent portion 242 are connected, the assembly sequence is reasonable, and the probability of assembly positioning size deviation is reduced.

[0041] In an embodiment, the connecting member 3 is provided with a radially extending extension portion 31 away from one end of the connecting hole. The extension portion 31 is provided with an adjusting piece 5 between the extension portion 31 and the bracket 2. The diameter of the adjusting piece 5 is greater than the diameter of the second through hole 22. The adjusting piece 5 covers the second through hole 22. The extension portion 31 abuts against the adjusting piece 5 to the bracket 2 along the axial direction. When the connecting member 3 is installed to the connecting hole, the extension portion 31 is close to the connecting hole along the axial direction, and further pushes the adjusting piece 5 to cover the second through hole 22 and abut against the bracket 2. The bracket 2 is abutted to the sub-frame 1 under the action of the connecting member 3, and further makes the sub-frame 1 assembled to the vehicle body.

[0042] Through the above arrangement, the connecting member 3 is installed to the connecting hole, and the whole sub-frame assembly 100 structure can be directly and integrally abutted to the vehicle body, and the structure is simple. The adjusting piece 5 can fill the gap between the extension portion 31 and the bracket 2, so that the sub-frame assembly 100 is firmly assembled and is not easy to loosen and make abnormal sound.
