[0024] Typical implementation modes reflecting the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different implementation modes, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0025] Refer to Figures 1 to 6 , the vehicle-mounted box of this embodiment mainly includes a box body 1, a slide rail mechanism 3 and a limiting bracket 4 installed in the box body 1, and a box door 2 that can be opened and closed relative to the box body 1.

[0026] This vehicle-mounted box can be used to be transported along with a transport vehicle such as a tanker truck or a semi-trailer truck. A connecting plate can be provided outside the box body 1 and installed and fixed to the frame or other structure of the transport vehicle by fasteners or other connection methods. For details, reference can be made to related technologies.

[0027] In this embodiment, the box body 1 includes a top plate 11 and a bottom plate 12 that are opposite up and down, opposite side plates 13 connected to both sides of the top plate 11 and the bottom plate 12, and an end plate 14 connected to one end of the top plate 11, the bottom plate 12 and the side plates 13. The top plate 11, the bottom plate 12, the two side plates 13 and the end plate 14 enclose to form an accommodation cavity 16 inside, and the accommodation cavity 16 has an opening 17 opposite to the end plate 14.

[0028] Refer to Figure 3 , at the end of the top plate 11, that is, at one end corresponding to the opening 17, there is an eaves edge 111 bent downward, and the eaves edge 111 defines the upper edge of the opening 17 of the box body 1. Preferably, a reinforcement member 112 is also attached to the inner side of the eaves edge 111. In this embodiment, the reinforcement member 112 is a square tube, and the reinforcement member 112 is attached to the bent corner of the top plate 11 for reinforcement. In particular, it can improve the strength of the eaves edge 111, thereby facilitating the reduction of the thickness of the top plate 11 and the lightweight of the box body 1.

[0029] Refer to Figure 4, at the end of the bottom plate 12, which corresponds to one end of the opening 17, there is a cill edge 121 bent upward, and the cill edge 121 defines the lower edge of the opening 17 of the box body 1. The cill edge 121 is L-shaped, having an upright section 1211 extending upward and a horizontal section 1212 bent and extended outward from the upper end of the upright section 1211. A sealing cotton 61 is also provided at the end of the horizontal section 1212.

[0030] Refer to Figure 1 and Figure 2 , the two slide rail mechanisms 3 are located in the accommodation cavity 16 of the box body 1 and are respectively arranged on the two side plates 13 of the box body 1. In the height direction, the slide rail mechanism 3 is close to the top plate 11 of the box body 1. The slide rail mechanism 3 includes a slide rail 31 and a mounting seat 32 slidably arranged on the slide rail 31. In this embodiment, preferably, the slide rail 31 is fixed to the side plate 13 through a support seat 33. In addition, the slide rail mechanism 3 is provided with a limit block 34 at the end corresponding to the opening 17 of the box body 1.

[0031] The support seat 33 includes a connecting plate 332 and a support plate 331 connected at an angle, and a reinforcing plate 333 arranged between the connecting plate 332 and the support plate 331. The connecting plate 332 and the support plate 331 can be integrally bent and formed and extend between the opening 17 and the end plate 14 of the box body 1. The connecting plate 332 is attached to the side plate 13, and the connecting plate 332 can be fixedly connected to the side plate 13 through fasteners or by welding. The support plate 331 protrudes into the accommodation cavity 16 of the box body 1 and is preferably inclined downward in the direction from the opening 17 to the end plate 14. A plurality of reinforcing plates 333 can be arranged at intervals to strengthen the support plate 331.

[0032] The slide rail 31 is installed on the support plate 331 of the support seat 33 and is supported by the support plate 331. Optionally, the slide rail 31 can be fixedly connected to the support plate 331 through fasteners. The slide rail 31 extends between the opening 17 and the end plate 14 of the box body 1 along with the support plate 331 and is inclined downward in the direction from the opening 17 to the end plate 14. There is an angle α between the slide rail 31 and the horizontal plane, and the angle α can be of an appropriate size, for example, 1° to 5°. The slide rail 31 is parallel to the side plate 13. The installation position of the slide rail 31 on the support plate 331 is close to the end of the support plate 331 and has a gap with the side plate 13, so as to deviate from the side joint of the box body 1 and the box door 2.

[0033] The mounting seat 32 is installed on the slide rail 31 through a matching slider, so as to be able to slide along the slide rail 31. There is also a gap between the mounting seat 32 and the side plate 13.

[0034] The limiting block 34 is fixedly installed on the lower surface of the support plate 331, and it can be fixedly connected to the support plate 331 through fasteners. The limiting block 34 is arranged corresponding to the opening 17 of the box body 1, and the outer surface of the limiting block 34 is generally flush with the opening 17 of the box body 1 or slightly indented into the box body 1.

[0035] Refer to Figure 1 and Figure 6 , two limiting brackets 4 are respectively fixed on the two side plates 13 of the box body 1, corresponding to being above the slide rail 31, and the installation positions of the limiting brackets 4 on the side plates 13 are close to the opening 17 of the box body 1. Optionally, the limiting brackets 4 are fixedly welded to the side plates 13. In this embodiment, the limiting bracket 4 includes a bracket plate 41 and two wing plates 42 respectively connected to the two ends of the bracket plate 41, thus forming a trough-shaped structure. The bracket plate 41 and the wing plates 42 are both vertically connected to the side plate 13, and the trough-shaped opening faces downward. The bracket plate 41 is parallel to the slide rail 31.

[0036] Refer to Figure 1 and Figure 2 , the box door 2 includes a box door main body 21 and mounting ears 22 protruding inside the box door main body 21. The mounting ears 22 are located on both sides of the upper end of the box door main body 21 to respectively correspond to two groups of slide rail mechanisms 3. The mounting ears 22 have a certain interval from the side edge of the box door main body 21 to be adapted to the position of the slide rail 31 of the slide rail mechanism 3. Preferably, a door lock mechanism 5 is further installed at the lower end of the box door 2.

[0037] The outer shape and size of the box door main body 21 can close the opening 17 of the box body 1, and its specific structural shape can be adaptively adjusted according to actual requirements. It is worth mentioning that the upper end of the box door main body 21 is formed with a butting edge 23 bent inward, and the box door 2 forms an avoidance position at the corner position outside corresponding to the butting edge 23. The butting edge 23 is provided with sealing cotton 62.

[0038] The mounting ears 22 extend into the accommodation cavity 16 of the box body 1 and are rotatably connected to the mounting seats 32 of the slide rail mechanism 3, so that the box door 2 can open and close relative to the box body 1. Among them, the mounting ears 22 are provided with rotating shaft holes and can form a rotating connection with the mounting seats 32 through rotating shafts.

[0039] As Figure 2 shown, when the mounting seat 32 is close to the opening 17 position, the box door 2 can close relative to the box body 1, the box door main body 21 closes the opening 17 of the box body 1, and plays a role in dust prevention and waterproofing for the accommodation cavity 16 inside the box body 1. As the slide rail mechanism 3 and the mounting ears 22, which are the connection structures between the box door 2 and the box body 1, are both enclosed inside the box body 1, they are less affected by the external environment. At this time, the limiting block 34 on the slide rail mechanism 3 can abut against the box door main body 21 to limit the box door 2.

[0040] Refer to Figure 3, when the box door 2 is closed, the docking edge 23 at the upper end of the box door 2 is located inside the reinforcing member 112 of the top plate 11. The sealing cotton 61 on the docking edge 23 is in sealing contact with the inner side surface of the reinforcing member 112, and the eaves edge 111 shields the outside of the docking edge 23. The reinforcing member 112 and the eaves edge 111 are located at the clearance position outside the docking edge 23 of the box door 2. Through the structural cooperation between the eaves edge 111 of the top plate 11 and the docking edge 23 of the box door 2, the upper joint between the box door 2 and the box body 1 cannot communicate directly with the inside of the accommodation cavity 16, improving the dust and waterproof effects.

[0041] Refer to Figure 4 , when the box door 2 is closed, the lower end of the box door 2 covers the outside of the sill edge 121 of the bottom plate 12. The lower end of the box door 2 extends downward beyond the sill edge 121, and the sealing cotton 62 at the end of the sill edge 121 is in sealing contact with the box door main body 21. Through the structural cooperation between the box door 2 and the sill edge 121, the lower joint between the box door 2 and the box body 1 cannot communicate directly with the inside of the accommodation cavity 16, also improving the dust and waterproof effects.

[0042] At this time, the lower end of the box door 2 can also be locked with the sill edge 121 through the door lock mechanism 5. Specifically, the door lock mechanism 5 includes a lock rod 51 and a knob 52. The lock rod 51 is in a long strip shape and is located inside the box door 2; the knob 52 is rotatably inserted through the box door main body 21 and is connected to one end of the lock rod 51. The operating part of the knob 52 is exposed outside the box door main body 21; by manually operating the knob 52 to rotate, the lock rod 51 can be driven to rotate, and the lock rod 51 can extend downward or lift upward. When the box door 2 is closed, the lock rod 51 is located inside the sill edge 121 and extends downward beyond the horizontal section 1212 of the sill edge 121, and the upright section 1211 of the sill edge 121 can block the outward movement of the lock rod 51, thus preventing the box door 2 from being opened and maintaining the closed state of the box door 2.

[0043] When the box door 2 needs to be opened, by rotating the knob 52, the lock rod 51 is lifted upward, and the lock rod 51 is disengaged from the sill edge 121, then the box door 2 can be operated to rotate and open.

[0044] As Figure 5 shown, when the box door 2 is opened, the mounting ear 22 of the box door 2 rotates relative to the mounting seat 32, and the box door main body 21 can be lifted upward from the opening 17.

[0045] Refer to Figure 6, after the box door 2 is fully opened, the box door 2 can slide into the box body 1 along with the movement of the mounting seat 32 on the slide rail 31 until it abuts against the end plate 14, and thus is received between the top plate 11 and the slide rail 31. In this embodiment, a stop block 18 is installed on the end plate 14, and the docking edge 23 of the box door 2 abuts against the stop block 18 to limit the sliding of the box door 2 into the box body 1. At this time, the upper end of the box door 2 remains connected to the slide rail mechanism 3 through the mounting ear 22, and the positions of both sides of the box door 2 close to the opening 17 are supported by the limit brackets 4. Thus, the box door body 21 is inclined downward in the direction towards the end plate 14, and the box door 2 cannot slide out freely, maintaining the stability of the position of the box door 2 in this state. In this state, the box door 2 only occupies a small part of the height at the upper end of the opening 17, and basically does not block the opening 17, facilitating personnel operation.

[0046] When the box door 2 needs to be closed again, pull the box door 2 outwards, so that the box door 2 slides outwards along with the mounting seat 32 along the slide rail 31. When the mounting seat 32 slides to a certain position, the box door 2 is disconnected from the limit bracket 4, and then through the relative rotation of the mounting ear 22 and the mounting seat 32, the box door 2 is turned downward. At the same time, the mounting seat 32 continues to move along the slide rail 31 until it is close to the opening 17 position, and the box door 2 can be rotated to the Figure 2 closed state as shown.

[0047] In summary, in the vehicle-mounted box of the present invention, when the box door 2 is closed, the mounting ear 22 and the slide rail mechanism 3, which are the connection structures between the box door 2 and the box body 1, are both enclosed inside the box body 1, less affected by the external environment, and not easily damaged due to environmental factors, making the connection between the box door 2 and the box body 1 more reliable, the box door 2 not easily falling off or being damaged, reducing the maintenance cost, and increasing the service life of the vehicle-mounted box. After the box door 2 is opened by rotating relative to the mounting seat 32, the box door 2 can slide into the box body 1 along the slide rail 31 and is received between the top plate 11 and the slide rail 31 of the box body 1, basically not occupying the lower area inside the box body 1 and the outer area opposite to the opening 17 of the box body 1, increasing the operating space for the operator and facilitating use. At the same time, when the box door 2 is received in the box body 1, it is supported by the limit brackets 4 to be in a downwardly inclined shape towards the inside of the box, so that the box door 2 cannot slide out freely, increasing the reliability and safety of use.
