[0032] Please refer to Figures 1-10 , this embodiment provides a technical solution: a carrier chassis device for the upper installation of a new energy commercial vehicle, including a carrier chassis 3 and an upper installation 1 installed on the carrier chassis 3. The upper installation 1 is a box body or a cabinet. A lower connecting member 6 is provided on the carrier chassis 3, and an upper connecting member 5 corresponding to the position of the lower connecting member is provided at the bottom of the upper installation 1. The upper connecting member 5 is cooperatively connected with the lower connecting member 6;

[0033] The upper connecting member 5 includes a U-shaped frame 501, a positioning plate 502, a positioning hole 503 and a guide hole 504;

[0034] The lower connecting member 6 includes an L-shaped plate 601, a self-locking nut 602, a guide head 603 and a reinforcing rib 604;

[0035] The connection between the lower connecting member 6 and the upper connecting member 5 is realized by the guide head 603 passing upward through the guide hole 504 and the positioning hole 503.

[0036] Integrate the electrical connector between the upper body 1 and the in-vehicle system of the new energy commercial vehicle. The wiring harness of the upper body 1 is concentrated at the rear of the carrier chassis 3 and uses a waterproof plug. At the same time, corresponding plugs are reserved at the rear of the carrier chassis 3 to reduce the complexity of the circuit and improve the reliability and stability of the electrical system. The integrated electrical connector has the characteristics of waterproof, dustproof, and shockproof, and can adapt to various harsh working environments. A refrigeration unit 2 is arranged at the upper position on one side of the upper body 1. The refrigeration unit is connected to the in-vehicle system of the new energy commercial vehicle through a wiring harness. The upper body 1 is made of lightweight materials to reduce the vehicle weight and improve the energy utilization rate. A temperature control system and a humidity control system electrically connected to the in-vehicle system are arranged on the refrigerated box type and aquatic product transportation box to ensure the quality of the goods.

[0037] Among them, the top of the U-shaped frame 501 is welded to the bottom of the upper body 1. The positioning plate 502 is fixed on the U-shaped bottom wall of the U-shaped frame 501. A positioning hole 503 is arranged on the positioning plate 502. A guiding hole 504 is opened at the center of the U-shaped bottom wall of the U-shaped frame 501, and the guiding hole 504 communicates with the positioning hole 503.

[0038] Among them, the guiding hole 504 is an elliptical hole, and the positioning hole 503 is a cross-shaped hole. The aperture size of the cross-shaped hole is greater than or equal to the major axis aperture of the elliptical hole.

[0039] Among them, the side plate of the L-shaped plate 601 is welded to the carrier chassis 3. A through hole is opened on the top plate of the L-shaped plate 601 and a self-locking screw 606 is passed through it. The top of the self-locking screw 606 passes upward through the top plate of the L-shaped plate 601 and a guiding head 603 is fixed. The self-locking screw 606 located below the top plate of the L-shaped plate 601 is threadedly connected with a self-locking nut 602.

[0040] Among them, a reinforcing rib 604 is fixed on the side plate of the L-shaped plate 601.

[0041] Among them, a refrigeration unit 2 is installed at the upper position on one side of the upper body 1, and the refrigeration unit 2 is controlled by the in-vehicle system of the new energy commercial vehicle.

[0042] Among them, after the upper connecting member 5 and the lower connecting member 6 pass through the guiding hole 504 and the positioning hole 503 through the guiding head 603, the guiding head is rotated by rotating the self-locking screw, and the connection is locked by the self-locking nut 602.

[0043] Among them, a gasket 605 is arranged on the self-locking nut 602.

[0044] Among them, the upper connecting member 5 is arranged at the four corner positions at the bottom of the upper body 1, and the lower connecting member 6 is arranged at the four corner positions on the carrier chassis 3. The upper and lower positions of the upper connecting member 5 and the lower connecting member 6 correspond to each other one by one.

[0045] The working principle is as follows: When replacing the upper installation 1, loosen the self-locking nut 602 downward manually, push the self-locking screw rod 606 upward to drive the guiding head 603 to disengage from the positioning hole 503 upward, and then manually rotate the self-locking screw rod 606 to drive the guiding head 603 to rotate. The rotation angle is 90 degrees, so that the guiding head 603 can pass downward through the positioning hole 503 and the guiding hole 504. Pull the self-locking screw rod 606 downward to drive the guiding head 603 to be removed from between the positioning plate 502 and the U-shaped frame 501. The guiding heads 603 at the four positions at the four corners on the lower side of the upper installation 1 are all removed in the same way. Thus, the U-shaped frame 501 and the L-shaped plate 601 are in a separable state, and the upper installation 1 can be removed by a crane and a new upper installation 1 can be replaced. Furthermore, an upper installation that meets the needs of transporting goods can be replaced, enabling the commercial vehicle body to be used for multiple purposes. Different transport cargo boxes can be selected according to the actual transport demand, improving the usage efficiency. When installing the upper installation 1, rotate the angle of the guiding head 603 so that the guiding head 603 is aligned with the guiding hole 504 on the upper installation 1. After placing the upper installation 1 on the carrier chassis 3, manually push the self-locking screw rod 606 upward to pass the guiding head 603 through the guiding hole 504 and the positioning hole 503. Then manually rotate the self-locking screw rod 606 to drive the guiding head 603 to rotate 90 degrees, and then manually pull the self-locking screw rod 606 downward. After the bottom of the guiding head 603 is caught in the positioning hole 503, lock the self-locking nut 602 on the lower side of the L-shaped plate 601, so that the L-shaped plate 601 and the U-shaped frame 501 are locked and fixed, and the connection between the upper installation 1 and the carrier chassis 4 is fixed, ensuring the installation stability of the upper installation 1.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
