[0031] At present, with the promotion of new energy vehicles such as light trucks and small trucks, their long-range battery packs are often arranged in the middle of the frame. Under this condition, other components such as brake compressors, brake pumps, batteries, lift pumps, domain control systems, etc. need to be arranged on both sides of the frame through brackets. The brackets include adapter components for assembly to the frame.
[0032] According to research, in order to provide a larger fitting area between the adapter component and the rest of the bracket, the adapter component generally needs to be designed as a complex bending structure, so as to increase the welding path length between the adapter component and the rest of the bracket, thereby improving the connection strength between the adapter component and the rest of the bracket. Since the bending scheme of the adapter component is relatively complex, the production process of the adapter component itself is also relatively complex, the production cost is high, and the welding between the adapter component and the rest of the bracket is difficult.
[0033] In order to solve the problems in the prior art, the present application provides a vehicle expansion bracket assembly and a vehicle, which are described in detail below with reference to the accompanying drawings.
[0034] Figure 1 This is a schematic diagram of the structure of assembling a vehicle expansion bracket assembly to a vehicle frame in some embodiments of the present application; Figure 2 This is a schematic diagram of the structure of a vehicle expansion bracket assembly in some embodiments of the present application; Figure 3 This is a schematic diagram of the assembly structure of the lap beam and the transition component in some embodiments of the present application; Figure 4 This is a schematic diagram of the structure of the adapter component in some embodiments of the present application.
[0035] See also Figures 1 to 4 The embodiment of the present application provides a vehicle expansion bracket assembly, which can be connected to a vehicle frame 1 for use. The expansion bracket assembly includes a bracket body 2 and an adapter component 3. The bracket body 2 is a frame structure for carrying some components of the vehicle, such as a brake compressor, a brake pump, a battery, a lift pump, a domain control system, etc. The bracket body 2 includes a tubular lap beam 211; the adapter component 3 is used to assemble the expansion bracket assembly to the vehicle frame 1. The adapter component 3 extends along a first direction X, and the adapter component 3 has a The lap beam 211 is adapted to the first lap hole 313, and the extension direction of the first lap hole 313 is parallel to the second direction Y, and the second direction Y is perpendicular to the first direction X. The lap beam 211 passes through at least part of the inner area of the first lap hole 313, and the lap beam 211 is fixedly connected to the first lap hole 313. It can be understood that the lap beam 211 can be fixedly connected to the first lap hole 313 by bonding or welding, for example, the edges where the lap beam 211 and the first lap hole 313 are connected are welded.
[0036] It should be noted that the verticality in the present application is not absolute verticality, and the verticality within the allowable error range is also within the protection scope of the present application, for example, the angle between the two may also be 92°, 91°, 90.5°, 89.5°, 89°, 88°, etc.; the parallelism in the present application is not absolute parallelism, and the parallelism within the allowable error range is also within the protection scope of the present application, for example, the angle between the two may also be 2°, 1°, 0.5°, etc.
[0037] During the process of assembling the expansion bracket assembly to the frame 1 through the adapter component 3, it is configured so that the first direction X is perpendicular to the horizontal plane, so that after the gravity of the components carried by the bracket body 2 acts on the bracket body 2, it can be directly transmitted to the adapter component 3 through the hole wall of the first lap hole 313, that is, only by welding the edges where the lap beam 211 and the first lap hole 313 are connected, the bracket body 2 and the adapter component 3 can have a higher connection strength. Therefore, there is no need to set a longer welding path between the lap beam 211 and the adapter component 3, which can simplify the bending scheme of the adapter, reduce the production process difficulty and production cost of the adapter itself, and reduce the welding difficulty of the adapter component 3 and the bracket body 2.

The adapter plate 31 is used as the adapter component 3, and the structure is simple; when the edges where the lap beam 211 and the first lap hole 313 are connected are welded, the welding path between the two is a straight line, which is convenient for welding; after the bolt hole 312 is provided, the adapter plate 31 can be assembled to the frame 1 by bolt connection, and the assembly method is relatively simple.

By providing the reinforcement 32, the structural strength of the adapter component 3 itself can be improved, and the risk of the adapter component 3 producing a large deformation under the action of external force can be reduced.

[0042] like Figure 5 and Figure 6 As shown, in some embodiments, the reinforcement 32 includes a reinforcement main board 321 and two side walls 322 respectively fixed to the reinforcement main board 321, the two side walls 322 are respectively located on both sides of the reinforcement main board 321 along the third direction Z, the edges of the side walls 322 away from the reinforcement main board 321 are welded to the adapter plate 31, and the third direction Z is perpendicular to the first direction X and the second direction Y at the same time, that is, each side wall 322 is respectively connected to the reinforcement main board 321 and the adapter plate 31, so the side wall 322 is not easy to deform, thereby further improving the structural strength of the reinforcement 32.
[0043] In some embodiments, the first lap hole 313 includes a first sub-hole located on the adapter plate 31 and a second sub-hole located on the reinforcing main plate 321, and the lap beam 211 is simultaneously connected to the first sub-hole and the second sub-hole, that is, the edge where the first sub-hole connects to the lap beam 211 and the edge where the second sub-hole connects to the lap beam 211 can be welded together, which can further improve the connection strength between the adapter plate 31 and the lap beam 211.

It can be understood that the reinforcing beam 212 can be fixedly connected to the second lap hole 311 by bonding or welding. Specifically, in this embodiment, the edges where the reinforcing beam 212 and the second lap hole 311 are connected are welded. The reinforcing beam 212 cooperates with the second lap hole 311, which can improve the structural strength of the bracket body 2 itself on the one hand, and can improve the connection strength between the bracket body 2 and the adapter component 3 on the other hand.
[0045] like Figure 1 and Figure 2 As shown, in some embodiments, the bracket body 2 also includes a first frame body 21 and a second frame body 22 relatively arranged along the second direction Y, and the first frame body 21 and the second frame body 22 both include a plurality of lap beams 211 spaced apart along the third direction Z and a bottom beam 213 fixedly connected between adjacent lap beams 211, and each lap beam 211 is correspondingly provided with a transition component 3. By providing the first frame body 21 and the second frame body 22, the bracket body 2 can carry relatively more parts; by providing a plurality of lap beams 211 and the transition component 3, the connection strength between the bracket body 2 and the frame 1 can be improved.

When the expansion bracket assembly is assembled to the vehicle frame 1 through the top of the adapter component 3, and the expansion bracket assembly is loaded with corresponding parts, the torque generated by the gravity of the above-mentioned parts around the connection position between the adapter component 3 and the vehicle frame 1 will drive the bottom of the first frame 21 and the bottom of the second frame 22 to be close to each other. By setting the cross beam 4, it can play a certain supporting role on the first frame 21 and the second frame 22 along the second direction Y, and can improve the overall bending strength of the vehicle expansion bracket assembly.
[0047] In some embodiments, a sleeve is sleeved in the middle of the cross beam 4 , which can improve the bending strength of the cross beam 4 , and further improve the bending strength of the vehicle expansion bracket assembly as a whole.
[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the middle position of the cross beam 4 is configured as a structure extending along a curve bent in space to avoid chassis components at corresponding positions.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the crossbeam 4 is fixed to the overlapping section 2112 by a locking bolt, and the axis of the locking bolt is parallel to the first direction X. The bolt connection method between the crossbeam 4 and the overlapping section 2112 is relatively simple compared to other connection methods, which can reduce the connection difficulty between the two and improve the assembly efficiency between the two. The corresponding end surface of the crossbeam 4 abuts against the first side surface 2113, and when the bottom of the first frame 21 and the bottom of the second frame 22 are close to each other, the torque carried by the bolt can be shared.
