[0019] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and the description are illustrative in nature and are not used to limit the protection scope of the claims.

[0020] As Figures 1 to 4 shown, a positioning and installation structure for the upper mounting of a commercial vehicle is used for positioning and installation fixation during the assembly of a commercial vehicle cargo box 4 and a commercial vehicle chassis 1. It includes a chassis positioning seat 2 installed on the commercial vehicle chassis 1. A cargo box positioning seat 3 is provided directly above the chassis positioning seat 2, and the cargo box positioning seat 3 is installed on the commercial vehicle cargo box 4. A lower positioning upper mounting hole is provided through the chassis positioning seat 2, and a positioning upper mounting device is detachably assembled with the chassis positioning seat 2 through the lower positioning upper mounting hole. An upper positioning upper mounting hole is provided through the cargo box positioning seat 3, and the upper end of the positioning upper mounting device passes through the upper positioning upper mounting hole. In this embodiment, multiple sets need to be arranged on the periphery of the commercial vehicle for cooperative use to achieve the positioning of the commercial vehicle cargo box 4 in the front, rear, left, and right four directions, so as to improve its positioning effect. During use, it is necessary to first fix the chassis positioning seat 2 to the commercial vehicle chassis 1 and the cargo box positioning seat 3 to the commercial vehicle cargo box 4, and then connect and assemble the positioning upper mounting device with the chassis positioning seat 2. During the hoisting and lowering process of the commercial vehicle cargo box 4, by pushing and adjusting the commercial vehicle cargo box 4, the positioning upper mounting device is inserted into the corresponding cargo box positioning seat 3, thereby realizing the positioning of the commercial vehicle cargo box 4.

[0021] Specifically, the positioning upper mounting device includes a positioning pin shaft 5. The bottom end of the positioning pin shaft 5 is fixedly connected with a pin shaft fixing plate 6. The pin shaft fixing plate 6 is movably limited below the lower positioning upper mounting hole. A positioning upper mounting bolt 7 is arranged through the pin shaft fixing plate 6. The positioning upper mounting bolt 7 sequentially passes through the chassis positioning seat 2 and the cargo box positioning seat 3. And positioning upper mounting nuts 8 are respectively threadedly assembled on each of the positioning upper mounting bolts 7. By using the fitting of the positioning pin shaft 5 and the corresponding upper positioning upper mounting hole, the positioning between the chassis positioning seat 2 and the corresponding cargo box positioning seat 3 is realized, that is, the upper mounting positioning of the commercial vehicle cargo box 4 is realized. After the positioning is completed, the pin shaft fixing plate 6 and the positioning pin shaft 5 can be used to connect the chassis positioning seat 2 and the corresponding cargo box positioning seat 3 through the positioning upper mounting bolt 7.

[0022] To improve the fixing property of the connection between the chassis positioning seat 2 and the cargo box positioning seat 3, it further includes an upper mounting locking bolt 9 detachably arranged through the chassis positioning seat 2 and the upper positioning upper mounting hole. An upper mounting locking nut 10 is threadedly assembled with the upper mounting locking bolt 9. And the positioning pin shaft 5 and the pin shaft fixing plate 6 are used during upper mounting positioning, and the upper mounting locking bolt 9 and the upper mounting locking nut 10 are used during installation. Thus, it can be seen that the upper mounting locking bolt 9 and the positioning pin shaft 5 are used alternately, that is, the positioning pin shaft 5 is used during upper mounting positioning, and the upper mounting locking bolt 9 is used when connecting and fixing the chassis positioning seat 2 and the cargo box positioning seat 3.

[0023] In this embodiment, an installation cushion block 11 is detachably arranged between the chassis positioning seat 2 and the cargo box positioning seat 3. A through hole for facilitating the passing of the positioning upper mounting device is arranged through the installation cushion block 11. After the upper mounting positioning is completed, the installation cushion block 11 is inserted between the corresponding chassis positioning seat 2 and the cargo box positioning seat 3 to improve the tightness of their contact, thereby improving the support strength for the cargo box positioning seat 3 and making its installation fixing property better.

[0024] The chassis positioning seat 2 and the cargo box positioning seat 3 are respectively arranged as folding plates with an L-shaped end face. And the corners of the chassis positioning seat 2 and the corners of the cargo box positioning seat 3 are respectively arranged with arc angles for smooth transition. Triangular reinforcing angle plates 12 are respectively arranged and mounted on the chassis positioning seat 2 and the cargo box positioning seat 3, so that the overall strength of the chassis positioning seat 2 and the cargo box positioning seat 3 is relatively large, the load-bearing capacity is strong, the service life is long, and it helps to stably support the commercial vehicle cargo box 4.

[0025] Mounting holes 13 are respectively arranged through the chassis positioning seat 2 and the cargo box positioning seat 3. The center line of the mounting hole 13 on the chassis positioning seat 2 and the center line of the lower positioning upper mounting hole, and the center line of the mounting hole 13 on the cargo box positioning seat 3 and the center line of the upper positioning upper mounting hole are respectively arranged perpendicular to each other in space. The mounting holes 13 on the chassis positioning seat 2 and the mounting holes 13 on the cargo box positioning seat 3 are respectively arranged in a linear or triangular shape. Through the arrangement of the mounting holes 13, the corresponding positioning seats can be installed and fixed by means of mounting bolts, making it convenient to disassemble and replace them.
