[0019] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0020] First embodiment
[0021] The utility model provides a latch seat structure, such as Figure 1 As shown, the latch seat structure of one embodiment includes a support member 11 and a support 12, the support member 11 is fixedly mounted on the support 12, the support 12 is provided with a mounting hole, and the support member 11 is provided with a through hole 111, the mounting hole is connected to the through hole 111 and is coaxially arranged, the aperture of the mounting hole is greater than or equal to the aperture of the through hole 111, and the mounting hole and the through hole 111 are used together for inserting the pin shaft.
[0022] In the latch seat structure and vehicle of the present invention, a support member 11 is fixedly installed on the support 12, and the pin shaft is inserted through the mounting hole and the through hole 111 to be supported and fixed by the support member 11. After the cargo box of the vehicle is lifted to a certain angle, the cargo box is further fixed by the latch seat structure, that is, the pin shaft is inserted into the mounting hole, the through hole 111 and the limit hole on the cargo box. At this time, the cargo box is fixed at the lifting angle, the structure is more solid, and the risk of unstable lifting of the cargo box is reduced; the support member 11 increases the strength of the overall latch seat structure, increases the contact area with the pin shaft, and prevents the pin shaft from breaking due to excessive load when the cargo box is lifted.
[0023] In this embodiment, the support member 11 is a cylinder, and the outer diameter of the support member 11 is equal to the diameter of the mounting hole. The support member 11 is placed in the mounting hole and fixedly connected to the support 12. It can be understood that the support member 11 is placed in the mounting hole along its own axis and is fixedly connected to the support 12 by welding. Figure 1 As can be seen from the structure, the support member 11 protrudes from both sides of the support 12. A through hole 111 is opened on the support member 11, and a fastener such as a pin is placed in the through hole 111 and the limit hole on the cargo box to achieve limited fixation. While limiting and fixing, the pin applies pressure to the support member 11 instead of directly applying force to the support 12. This enhances the strength of the overall pin seat structure and increases the contact area with the pin, effectively preventing the pin from breaking due to excessive lifting load on the cargo box.
[0024] In this embodiment, the ratio of the thickness (height) of the support member 11 to the thickness of the support 12 in the axial direction of the through hole 111 is 2:1 to 4:1. Preferably, in this embodiment, the ratio of the thickness of the support member 11 to the thickness of the support 12 is 3:1. Of course, those skilled in the art may set the ratio to 2:1, 3:1, 4:1, etc. according to actual conditions, and this is not a single limitation.
[0025] In this embodiment, the support member 11 includes a first portion 112, a second portion, and a third portion 113, which are connected in sequence. Axially, along the through hole 111, the thickness of the second portion is equal to the thickness of the support 12, and the thickness of the first portion 112 is equal to the thickness of the third portion 113. The first portion 112 and the third portion 113 are located on either side of the support 12. The first portion 112 and the third portion 113 on either side of the support 12 are configured to have the same thickness. This ensures uniform stress distribution across the entire structure, reduces stress concentration, and reduces the risk of damage due to excessive localized stress.
[0026] In this embodiment, the radial cross-sectional area of the ends of the support 12 decreases as they move away from the support 11. Specifically, the projection of the support 12 on the radial cross-section of the support 11 forms a generally triangular shape. A curved surface is formed between the two side surfaces of the support 12. This curved surface reduces stress concentration, thereby improving the strength and durability of the support 12.
[0027] The utility model also provides a vehicle, such as Figure 2-3 As shown, a vehicle according to one embodiment includes a vehicle frame 21, a cargo box 22, a tilting seat 23, and the latching seat structure described above. The tilting seat 23 is fixedly mounted to the vehicle frame 21 and located at the rear of the vehicle frame 21. The cargo box 22 is rotatably connected to the vehicle frame 21 via the tilting seat 23 to enable switching between transport and maintenance positions. The latching seat structure is fixedly connected to the tilting seat 23. When the cargo box 22 is in the maintenance position, the latching seat structure is fixedly connected to the cargo box 22 via a pin to prevent the cargo box 22 from rotating further about the tilting seat 23.
[0028] Specifically, the cargo box 22 is provided with a hinge hole 221 and a limit hole 222. The hinge hole 221 is connected with the flip seat 23 to enable the cargo box 22 to rotate around the flip seat 23. When the cargo box 22 is in the maintenance state, the through hole 111 and the limit hole 222 are coaxially corresponding, and the pin shaft is inserted into the through hole 111 and the limit hole 222 to limit the rotation of the cargo box 22, thereby achieving the effect of lifting and fixing the cargo box 22.
[0029] The installation diameter of the latch seat structure of this embodiment is smaller than that of mining dump trucks on the market, so that the movable angle of the cargo box when it is raised is only 6°. In addition, the installation position of the latch seat structure is higher, which shortens the force arm of the pin shaft when the cargo box is raised, and correspondingly reduces the stress on the pin shaft.
[0030] The latch seat structure of this embodiment can also serve as a trailer hook at the rear of the frame to facilitate vehicle transportation.
[0031] Second embodiment
[0032] The latch seat structure of this embodiment is similar to that of the first embodiment, except for the number of support members 11 and the installation and connection method between the support members 11 and the support 12.

[0033] In this embodiment, the support member 11 includes a first support member 114 and a second support member 115. The first support member 114 and the second support member 115 are both cylindrical. The first support member 114 is provided with a first through hole, and the second support member 115 is provided with a second through hole. The first support member 114 and the second support member 115 are respectively located on both sides of the support 12. The through hole 111 includes a first through hole and a second through hole. The first through hole, the mounting hole and the second through hole are coaxially arranged and interconnected. The first through hole, the mounting hole and the second through hole are jointly used for inserting the pin shaft.
[0034] In this embodiment, the diameters of the first through hole, the mounting hole, and the second through hole are all equal. When the cargo box is in the maintenance state, the pin extends into the first through hole, the mounting hole, the second through hole, and the limiting hole of the cargo box to achieve the effect of lifting and fixing the cargo box.
