This can limit the vertical freedom of the vehicle body 300, and the purpose of installing the vehicle body 300 is achieved through the receiving groove and the screw connection 22. The present application utilizes the existing connecting plate 11 and the shock-absorbing pad 12 in conjunction with the mounting seat 21 and the screw connection 22 to connect the chassis 200 with the vehicle body 300. The structure is simple, and the mounting seat 21 and the screw connection 22 are of small mass, which conforms to the lightweight design.

[0039] In one embodiment, see Figure 1 and Figure 5 The mounting seat 21 includes a seat body 211 and a mounting plate 212. The seat body 211 is installed on the floor frame 310 of the vehicle body 300. The seat body 211 is provided with a channel in the vertical direction. The mounting plate 212 is covered on the upper side of the seat body 211. The mounting plate 212 and the seat body 211 are jointly enclosed to form the accommodating groove.

[0040] In this embodiment, the seat body 211 is provided with a channel running through in the vertical direction, and the mounting plate 212 is installed at the upper end of the seat body 211 to block the upper end of the channel, thereby forming a receiving groove opening downward, and the first through hole is located in the middle of the mounting plate 212 and connected to the receiving groove.

[0041] In one embodiment, see Figure 1 and Figure 5 The seat body 211 and the mounting plate 212 are detachably connected.

[0042] In this embodiment, a plurality of threaded holes are provided on the upper side of the seat body 211, and the plurality of threaded holes are arranged in an array.

The bolts are passed through the channel and threadedly connected to the seat body 211 to install the mounting plate 212 on the seat body 211.

[0043] In one embodiment, see Figure 1 and Figure 4 The mounting seat 21 is mounted on the upper side of the floor frame 310 of the vehicle body 300 .

[0044] In this embodiment, in order to ensure the flatness of the bottom of the floor frame 310 and facilitate connection with the chassis 200, the mounting seat 21 is arranged on the upper side of the floor frame 310, that is, the mounting seat 21 is located on the inner side of the vehicle body 300, and the floor frame 310 is provided with an avoidance hole corresponding to the receiving groove, and the shock-absorbing pad 12 extends into the receiving groove through the avoidance hole.

[0045] In one embodiment, see Figure 1 The connection structure between the chassis and the vehicle body further includes a reinforcing plate 3 , which is disposed at the lower side of the floor frame 310 of the vehicle body 300 and corresponds to the mounting seat 21 .

[0046] In this embodiment, in order to ensure the connection strength between the vehicle body 300 and the chassis 200, a reinforcing plate 3 is further provided on the lower side of the floor frame 310. The cross-sectional area of ​​the reinforcing plate 3 is much larger than the cross-sectional area of ​​the mounting seat 21. By providing the reinforcing plate 3, the connection strength of the connection can be enhanced.

[0047] In one embodiment, the mounting seat 21 and the reinforcing plate 3 are both welded to the floor frame 310 of the vehicle body 300 .

[0048] In one embodiment, the smallest diameter of the receiving groove is D1, the diameter of the shock-absorbing pad 12 is D2, and D1-D2=5 mm.

[0049] In this embodiment, the receiving groove is used to accommodate the shock-absorbing pad 12, so the shape of the receiving groove is adapted to the shock-absorbing pad 12, and the shock-absorbing pad 12 is roughly cylindrical, so the part of the receiving groove that is adapted to the shock-absorbing pad 12 is cylindrical, and the receiving groove also needs to limit the shock-absorbing pad 12 circumferentially, so the diameter of the receiving groove cannot be too large or too small, and the diameter of the receiving groove at the smallest point can be 5 mm larger than the diameter of the shock-absorbing pad 12. Such a setting is convenient for assembly on the one hand, and can ensure circumferential limitation on the other hand.

The diameter of the first groove section 2111 is smaller than the diameter of the second groove section 2112. The diameter of the first groove section 2111 is D1.

[0051] In this embodiment, the seat body 211 is a square bowl-shaped structure formed by bending the sheet metal downward on all sides, and the cross-section of its internal space is square, which has a poor fit with the shock-absorbing pad 12. Therefore, a hole is also opened on the top of the seat body 211, and the hole constitutes the first groove section 2111, and the internal space constitutes the second groove section 2112.

[0052] In one embodiment, the depth of the receiving groove is smaller than the height of the shock absorbing pad 12 .

[0053] In this embodiment, the shock-absorbing pad 12 is made of elastic material, so that the shock-absorbing pad 12 has space to move in the vertical direction. In order to avoid collision between the floor frame 310 and the chassis 200, the depth of the receiving groove is smaller than the height of the shock-absorbing pad 12, so that the receiving groove can only cover the upper end part of the shock-absorbing pad 12 to reserve space for its movement.

[0054] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0055] During the specific installation, the connecting plate 11 is first installed on the chassis 200, and the shock-absorbing pad 12 is placed on the connecting plate 11 so that the second through hole corresponds to the third through hole, holes are pre-opened on the strong plate and the floor frame 310, and then the strong plate and the seat body 211 are welded to the floor frame 310, and the mounting part is installed on the seat body 211 by bolts, and then the entire vehicle body 300 is placed on the chassis 200 to ensure that the shock-absorbing pad 12 corresponds to the receiving groove, and finally connected by the screw member 22 to complete the assembly of the chassis 200 and the vehicle body 300.

[0056] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
