[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] The utility model embodiment provides a vehicle component, see Figure 1 , Figure 2 and Figure 3The vehicle assembly includes a frame 10 and a battery pack 20. The frame 10 is provided with a support beam 11 and a connecting beam 12. The support beam 11 and the connecting beam 12 are fixedly connected. The support beam 11 is used to support the weight of the vehicle, and the connecting beam 12 is used to connect to the battery pack 20. Among them, the extension direction of at least part of the support beam 11 is parallel to the direction from the rear of the vehicle to the front of the vehicle, and the extension direction of at least part of the support beam 11 is at an angle to the direction from the rear of the vehicle to the front of the vehicle, so that the support beam 11 can support the weight of the vehicle and connect the various assemblies of the vehicle. The extension direction of the connecting beam 12 and the extension direction of part of the support beam 11 can be the same, or they can have an angle; the position of the connecting beam 12 can be located at the front of the vehicle, or in the middle of the vehicle, or at the rear of the vehicle. The direction from the rear of the vehicle to the front of the vehicle is parallel to the direction from the rear of the vehicle to the front of the vehicle. Figure 1 Parallel to the X direction.

[0038] The present application provides a specific description by taking the example that the connecting beam 12 is located in the middle of the vehicle and the extending direction of the connecting beam 12 is parallel to the direction from the rear end to the front end of the vehicle.

[0039] A first sliding structure 13 is provided on the connecting beam 12, the battery pack 20 has a shell 21, and a second sliding structure 22 is provided on the shell 21. The first sliding structure 13 and the second sliding structure 22 are slidingly connected along the extension direction of the connecting beam 12, so that the frame 10 and the battery pack 20 are slidingly connected, which is beneficial to simplifying the assembly and after-sales maintenance and disassembly process between the battery pack 20 and the frame 10, reducing the number of parts in the installation process of the battery pack 20 and the frame 10, and is beneficial to improving production efficiency while reducing production costs and achieving lightweight.

[0040] Optionally, the first sliding structure 13 is a slide groove, and the second sliding structure 22 is a slider; or, the first sliding structure 13 is a slider, and the second sliding structure 22 is a slide groove, and the slide groove and the slider are slidably connected, thereby achieving fewer assembly processes between the battery pack 20 and the frame 10, and reducing the number of parts in the installation process of the battery pack 20 and the frame 10. Among them, a fixing mechanism can be set on the connecting beam 12, so that after the battery pack 20 and the connecting beam 12 are slidably connected to the specified position, the relative position of the battery pack 20 and the connecting beam 12 is fixed, thereby ensuring the stability of the position of the battery pack 20 and preventing the battery pack 20 from sliding relative to the connecting beam 12 when the vehicle moves.

[0041] Optionally, the number of connecting beams 12 may be 1, 2 or more. When the number of connecting beams 12 is 1, the battery pack 20 is supported and connected by a single connecting beam 12, the extension direction of the connecting beam 12 may be set arbitrarily, and a corresponding structure may be set on the shell 21 of the battery pack 20 so that the battery pack 20 is slidably connected to the connecting beam 12. When the number of connecting beams 12 is 2 or more, the extension directions of all connecting beams 12 are parallel to each other, and a connecting structure corresponding to the connecting beam 12 is set on the shell 21 of the battery pack 20 so that the battery pack 20 is slidably connected to the connecting beam 12.

[0042] Optionally, the extension direction of the connecting beam 12 is parallel to the direction from the rear to the front of the vehicle. Since the vehicle is longer in the direction from the rear to the front of the vehicle, the length of the connecting beam 12 can be longer, so that the length of the battery pack 20 can be longer, which is conducive to accommodating more battery cells, thereby increasing the power of the battery pack 20 and increasing the pure electric range of the entire vehicle.

[0043] By making the vehicle assembly include a frame 10 and a battery pack 20, the frame 10 is provided with a support beam 11 and a connecting beam 12, the support beam 11 and the connecting beam 12 are fixedly connected, a first sliding structure 13 is arranged on the connecting beam 12, the battery pack 20 has a shell 21, a second sliding structure 22 is arranged on the shell 21, the first sliding structure 13 and the second sliding structure 22 are slidingly connected along the extension direction of the connecting beam 12, so that the frame 10 and the battery pack 20 are slidingly connected, which is beneficial to simplifying the assembly process between the battery pack 20 and the frame 10 and the after-sales maintenance and disassembly process, reducing the number of parts in the installation process of the battery pack 20 and the frame 10, and is beneficial to improving production efficiency while reducing production costs and achieving lightweight.

[0044] In one implementation, see Figure 1 , Figure 2 , Figure 3 and Figure 4 There are two connecting beams 12, and the connecting beams 12 include a first connecting beam 121 and a second connecting beam 123. The first connecting beam 121 and the second connecting beam 123 are arranged at intervals so that there is a gap space between the first connecting beam 121 and the second connecting beam 123, so that at least part of the battery pack 20 can be accommodated in the gap space and connected to the first connecting beam 121 and the second connecting beam 123 to realize the connection between the battery pack 20 and the frame 10.

[0045] The extension direction of the first connecting beam 121 is parallel to the extension direction of the second connecting beam 123. The first connecting beam 121 and the second connecting beam 123 are both slidably connected to the shell 21, so that the battery pack 20, the first connecting beam 121 and the second connecting beam 123 are integrated into one, which improves the space utilization of the battery pack 20, and enables the part of the battery pack 20 located between the first connecting beam 121 and the second connecting beam 123 to play a certain supporting role for the first connecting beam 121 and the second connecting beam 123, thereby improving the bending and torsion resistance of the frame 10 and improving the carrying capacity of the entire vehicle; at the same time, it simplifies the assembly and after-sales maintenance and disassembly processes between the battery pack 20 and the frame 10, and reduces the number of parts in the installation process of the battery pack 20 and the frame 10, which is beneficial to improving production efficiency while reducing production costs and achieving lightweight.

[0046] Optionally, the first connecting beam 121 and the second connecting beam 123 are used as a slide groove, and the battery pack 20 is used as a slider, and the slide groove is slidably connected to the slider. The first connecting beam 121 and the second connecting beam 123 can be respectively located at the battery pack 20 Figure 1 On both sides of the Y direction, the battery pack 20 itself is accommodated in the slide groove as a slider and is slidably connected with the slide groove, that is, the battery pack 20 is Figure 1 The two surfaces opposite to each other in the Y direction and part of the upper and lower surfaces are accommodated in the slide groove, so that the battery pack 20 is slidably connected with the first connecting beam 121 and the second connecting beam 123. Therefore, the battery pack 20 can be slidably connected with the first connecting beam 121 and the second connecting beam 123 without installing other structures, which simplifies the assembly process between the battery pack 20 and the frame 10, reduces the number of parts in the installation process of the battery pack 20 and the frame 10, and is conducive to improving production efficiency, reducing production costs, and achieving lightweight.

[0047] In one implementation, see Figure 1 , Figure 2 , Figure 3 and Figure 6 The housing 21 includes a first beam 221 and a second beam 224. The first beam 221 is slidably connected to the first connecting beam 121, and the second beam 224 is slidably connected to the second connecting beam 123. The first beam 221 and the second beam 224 may be both located on the upper surface of the battery pack 20, or both located on the lower surface of the battery pack 20, or respectively located on the battery pack 20 at the bottom surface. Figure 1 The upper surface and the lower surface of the battery pack 20 are respectively the surfaces of the battery pack 20 in the Y direction. Figure 1 When the first beam 221 and the second beam 224 are both located on the upper surface of the battery pack 20, or both located on the lower surface of the battery pack 20, the battery pack 20 is Figure 1 The space in the Y direction is increased, which can accommodate more battery cells, thereby increasing the power of the battery pack 20 and increasing the pure electric range of the vehicle. Figure 1 When the two surfaces are opposite to each other in the Y direction, it is beneficial to increase the distance between the frame 10 and the ground and the space of the passenger compartment.

[0048] The first beam 221 and the second beam 224 can be fixedly connected to the housing 21, or can be an integrated structure, which is conducive to ensuring the structural stability of the battery pack 20 itself, thereby ensuring the connection stability between the battery pack 20 and the frame 10; and when the first beam 221 and the second beam 224 are an integrated structure with the battery pack 20, the installation process of the battery pack 20 is simplified, which is conducive to improving production efficiency and reducing production costs. It is understandable that the first beam 221 and the second beam 224 can be set on the original housing 21 of the battery pack 20, and the first beam 221 and the second beam 224 can also be set on a new housing 21, so that the original battery pack 20 is accommodated in the new housing 21 and integrated into one.

[0049] Optionally, slide grooves can be provided on both the first beam 221 and the second beam 224, and the first connecting beam 121 and the second connecting beam 123 serve as sliders. The slide grooves are slidably connected to the sliders, so that the volume of the battery pack 20 is larger, thereby being able to accommodate more battery cells, thereby increasing the power of the battery pack 20 and increasing the pure electric range of the vehicle.

[0050] Optionally, the first connecting beam 121 is provided with a first slide groove 131, the second connecting beam 123 is provided with a second slide groove 133, the first beam 221 is slidably connected to the first slide groove 131, and the second beam 224 is slidably connected to the second slide groove 133, so that the battery pack 20 and the frame 10 as a whole can be Figure 1 The length in the Z direction is kept consistent, which helps to avoid unused gaps between the frame 10 and other structures in the Z direction.

[0051] In one implementation, see Figure 1 , Figure 2 , Figure 3 and Figure 6 The first beam 221 and the second beam 224 are located at two ends of the housing 21 in a first direction. The first direction is the direction in which the first connecting beam 121 and the second connecting beam 123 are spaced apart. That is, the first direction is parallel to Figure 1 In the Y direction, the first beam 221 and the second beam 224 are respectively located at the housing 21 Figure 1 On the two surfaces facing each other in the middle Y direction, the battery pack 20 is completely accommodated in the gap space between the first connecting beam 121 and the second connecting beam 123, which is beneficial to reducing the total length of the battery pack 20 and the frame 10 in the Z direction, improving the space utilization of the battery pack 20 and the frame 10 in the Z direction, and at the same time can increase the distance between the frame 10 and the ground and the space of the passenger compartment; and the battery pack 20 as a whole is equivalent to the crossbeam of the frame 10, so that the battery pack 20 also participates in the lateral force transmission, thereby improving the bending and torsion resistance of the frame 10 and improving the carrying capacity of the whole vehicle.

[0052] The openings of the first slide groove 131 and the second slide groove 133 are arranged relative to each other, which is beneficial to reducing the total length of the battery pack 20 and the frame 10 in the Y direction, thereby improving the space utilization of the battery pack 20 and the frame 10 in the Y direction. While ensuring that the vehicle has a suitable distance between the frame 10 and the ground and the space in the passenger compartment, it ensures that more battery cells can be accommodated in the battery pack 20, thereby increasing the power of the battery pack 20 and the pure electric range of the whole vehicle.

[0053] In one implementation, see Figure 1 , Figure 2 , Figure 3 and Figure 6 The first beam 221 is provided with a first limiting structure 222, and the first connecting beam 121 is provided with a first limiting groove 132. The first limiting structure 222 is accommodated in the first limiting groove 132, so that the inner wall of the first limiting groove 132 limits the first limiting structure 222, thereby realizing that the first limiting groove 132 limits the first beam 221.

[0054] Similarly, the second beam 224 is provided with a second limiting structure 225, and the second connecting beam 123 is provided with a second limiting groove 134. The second limiting structure 225 is accommodated in the second limiting groove 134, so that the inner wall of the second limiting groove 134 limits the second limiting structure 225, thereby realizing that the second limiting groove 134 limits the second beam 224.

[0055] Optionally, the first limiting structure 222 and the second limiting structure 225 are both protrusions, which protrude from the first beam 221 and the second beam 224 along the Z direction and the opposite direction of the Z direction. The first limiting groove 132 and the first limiting structure 222 are correspondingly arranged, and the second limiting groove 134 and the second limiting structure 225 are correspondingly arranged. The first limiting structure 222 and the second limiting structure 225 are similar to reinforcing ribs, which are beneficial to ensure the strength of the first beam 221 and the second beam 224, and at the same time ensure that the structure of the first connecting beam 121 around the first limiting groove 132 has a certain thickness, and the structure of the second connecting beam 123 around the second limiting groove 134 has a certain thickness, thereby ensuring the strength of the first connecting beam 121 and the second connecting beam 123 themselves.

[0056] In one implementation, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The length of the first connecting beam 121 is greater than or equal to the length of the first beam 221, so that when the first connecting beam 121 and the first beam 221 are slidingly connected, the contact area between the first connecting beam 121 and the first beam 221 is increased, thereby ensuring the connection stability between the first connecting beam 121 and the first beam 221.

[0057] Similarly, the length of the second connecting beam 123 is greater than or equal to the length of the second beam 224, so that when the second connecting beam 123 and the second beam 224 are slidingly connected, the contact area between the second connecting beam 123 and the second beam 224 is increased, thereby ensuring the connection stability of the second connecting beam 123 and the second beam 224.

[0058] Optional, in Figure 1 In the X direction, the length of the first beam 221 and the length of the second beam 224 are both less than or equal to the length of the battery cell in the battery pack 20. When the length of the first beam 221 and the length of the second beam 224 are both equal to the length of the battery cell in the battery pack 20, it is beneficial to further increase the contact area between the first connecting beam 121 and the first beam 221, thereby ensuring the connection stability between the first connecting beam 121 and the first beam 221.

[0059] In one implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The first connecting beam 121 is provided with a first fixing mechanism 122, and the first fixing mechanism 122 is fixedly connected to the battery pack 20. Similarly, the second connecting beam 123 is provided with a third fixing mechanism 124, and the third fixing mechanism 124 is fixedly connected to the battery pack 20, which is beneficial to improving the connection stability between the first connecting beam 121, the second connecting beam 123 and the battery pack 20.

[0060] Optionally, the first fixing mechanism 122 and the third fixing mechanism 124 are both threaded holes, and there are multiple threaded holes, and the multiple threaded holes are arranged at intervals along the first connecting beam 121. The first connecting beam 121 and the second connecting beam 123 are respectively fixedly connected to the battery pack 20 through threaded columns, which is beneficial to reducing the installation bracket of the battery pack 20, thereby simplifying the assembly process between the battery pack 20 and the frame 10, and greatly improving production efficiency.

[0061] Optionally, the vehicle assembly further includes a first beam 221 and a second beam 224, wherein the first beam 221 is provided with a second fixing mechanism 223, which is fixedly connected to the first fixing mechanism 122, and the second beam 224 is provided with a fourth fixing mechanism 226, which is fixedly connected to the third fixing mechanism 124. The second fixing mechanism 223 and the fourth fixing mechanism 226 are both threaded holes, and the number of threaded holes is multiple, the spacing between the multiple threaded holes of the first fixing mechanism 122 is equal to the spacing between the multiple threaded holes of the second fixing mechanism 223, and the spacing between the multiple threaded holes of the third fixing mechanism 124 is equal to the spacing between the multiple threaded holes of the fourth fixing mechanism 226, so that the first fixing mechanism 122 and the second fixing structure can be fastened and connected by the same threaded column, and the third fixing mechanism 124 and the fourth fixing structure can be fastened and connected by the same threaded column, which is conducive to reducing the installation parts between the battery pack 20 and the frame 10, simplifying the assembly process between the battery pack 20 and the frame 10, and greatly improving production efficiency.

[0062] In one implementation, see Figure 2 , Figure 3 and Figure 5 The frame 10 further includes a limit bracket 14, which is fixedly connected to the connecting beam 12 and the support beam 11, respectively, so that the limit bracket 14 fixes the connecting beam 12 and the support beam 11, which is conducive to connecting various parts of the frame 10 into a whole. The limit bracket 14 is located on the side of the connecting beam 12 away from the battery pack 20, so that when the limit bracket 14 is installed, there is no need to interfere with the connection between the battery pack 20 and the connecting beam 12, which facilitates the installation of the limit bracket 14.

[0063] Optionally, the support beam 11 includes a front support beam 111 and a rear support beam 112, the front support beam 111 is located at the head of the vehicle, the rear support beam 112 is located at the rear of the vehicle, and the connecting beam 12 is located between the front support beam 111 and the rear support beam 112. The connecting beam 12 includes a first connecting beam 121 and a second connecting beam 123, and the limiting bracket 14 includes a first limiting bracket, a second limiting bracket, a third limiting bracket and a fourth limiting bracket. The first limiting bracket is fixedly connected to the first connecting beam 121 and the rear support beam 112, respectively, the second limiting bracket is fixedly connected to the second connecting beam 123 and the rear support beam 112, respectively, the third limiting bracket is fixedly connected to the first connecting beam 121 and the front support beam 111, and the fourth limiting bracket is fixedly connected to the second connecting beam 123 and the front support beam 111, respectively. Thus, the first connecting beam 121 and the second connecting beam 123 are fixedly connected to the front support beam 111 and the rear support beam 112, respectively, and the various parts on the frame 10 are connected as a whole.

[0064] Optionally, the first limiting bracket and the second limiting bracket are both provided with a plurality of threaded holes, and correspondingly, the first connecting beam 121, the second connecting beam 123 and the rear end support beam 112 are also provided with a plurality of threaded holes. When the first connecting beam 121 and the second connecting beam 123 are respectively spliced ​​with the rear end support beam 112, the third limiting bracket is respectively fixedly connected to the first connecting beam 121 and the rear end support beam 112 by a plurality of studs, and the fourth limiting bracket is respectively fixedly connected to the second connecting beam 123 and the rear end support beam 112 by another plurality of studs.

[0065] The length of the first connecting beam 121 is greater than that of the first beam 221, and the length of the second connecting beam 123 is greater than that of the second beam 224. After the first connecting beam 121 and the rear support beam 112 are spliced, the multiple threaded holes on the first connecting beam 121 are spaced apart from the battery pack 20; after the second connecting beam 123 and the rear support beam 112 are spliced, the multiple threaded holes on the second connecting beam 123 are spaced apart from the battery pack 20.

[0066] Similarly, the third limit bracket and the fourth limit bracket are both provided with a plurality of threaded holes, and correspondingly, the first connection beam 121, the second connection beam 123 and the front support beam 111 are also provided with a plurality of threaded holes. When the first connection beam 121 and the second connection beam 123 are respectively spliced ​​with the front support beam 111, the third limit bracket is respectively fixedly connected with the first connection beam 121 and the front support beam 111 by a plurality of studs, and the fourth limit bracket is respectively fixedly connected with the second connection beam 123 and the front support beam 111 by another plurality of studs.

[0067] Optionally, the limiting bracket 14 includes a first section 141 and a second section 142 that are connected, and the first section 141 and the second section 142 are respectively fitted with two adjacent surfaces of the connecting beam 12, and the first section 141 and the second section 142 are respectively fixedly connected to the connecting beam 12 and the support beam 11, so that the limiting bracket 14 can assist the connection beam 12 to be aligned with the support beam 11, and ensure the assembly clearance and flatness of the connection beam 12 and the support beam 11, thereby omitting the alignment step, which is beneficial to simplifying the installation process of the connection beam 12 and the support beam 11, and at the same time, it is beneficial to further increase the lateral fastening force and positioning accuracy of the connection between the connection beam 12 and the support beam 11, thereby ensuring the overall strength of the frame 10 itself.
