[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Combined with appendix Figures 1-5 A vehicle expansion structure for rapidly expanding the cargo hold volume of a vehicle includes a cargo box frame 10, which is a symmetrical structure at both ends. The cargo box frame 10 is a basic structure composed of metal frames. Metal plates for closure and cargo doors for entering and exiting the cargo hold can be installed on the cargo box frame 10.

[0027] The base warehouse surface on the bottom surface and the top surface is respectively connected between the two end carriage skeletons 10, and the base warehouse surface on the bottom surface and the top surface is also a plate structure made of metal. The base warehouse surface on the top surface and the bottom surface of the carriage skeleton 10 plays a role of closing the warehouse in any state of the expansion structure in the expanded state and the storage state.

[0028] The bottom plate 11 is rotatably connected to both sides of the base warehouse surface on the bottom surface of the carriage skeleton 10. The two side bottom plates 11 are symmetrical and rotatably installed at the bottom of the carriage skeleton 10. When the expansion structure is in the expanded state, the bottom plate 11 is in a horizontal state. When the expansion structure is in the storage state, the bottom plate 11 is in a vertical state.

[0029] The top plate 12 is rotatably connected to both sides of the base warehouse surface on the top surface of the carriage skeleton 10. The two side top plates 12 are symmetrical and rotatably installed at the top of the carriage skeleton 10. When the expansion structure is in the expanded state, the top plate 12 is in a horizontal state. When the expansion structure is in the storage state, the top plate 12 is in a vertical state.

[0030] The position state of the bottom plate 11 and the top plate 12 is changed to realize the switching of the expansion structure between the expanded state and the storage state. When the bottom plate 11 and the top plate 12 are rotated to the horizontal state, the bottom plate 11 and the top plate 12 respectively extend to both sides of the base warehouse surface on the bottom surface and the top surface of the carriage skeleton. At this time, the bottom plate 11 plays a supporting role, the top plate 12 plays a covering protection role, and the bottom plate 11 and the top plate 12 also play the same closing role as the base warehouse surface on the bottom surface and the top surface.

[0031] The rotation angle of the bottom plate 11 and the top plate 12 is 90 degrees. After the bottom plate 11 and the top plate 12 are in the horizontal state, the bottom plate 11 cannot be rotated downward, and the top plate 12 cannot be rotated upward. At this time, the bottom plate 11 plays a stable supporting effect, and the top plate 12 can protect the goods placed on the bottom plate 11. In other embodiments, the rotation angle of the bottom plate 11 and the top plate 12 can be greater than 90 degrees, so as to obtain a larger expansion space.

[0032] A push rod is arranged on the bottom plate 11 and the top plate 12 to realize the opening and supporting of the bottom plate 11 and the top plate 12. The push rod can be selected as an electric screw rod or a hydraulic rod.

[0033] The side compartment plates 13 are arranged on both sides of the carriage skeleton 10. The side compartment plate 13 is composed of two rotatably connected plates, and the side compartment plate 13 is also rotatably connected to the carriage skeleton 10.

[0034] The rotation connection between the two plates of the side panel 13 and between the side panel 13 and the compartment framework 10 adopts the same connection structure as the hinge connection, and the two plates of the side panel 13 can be folded in a "V" shape, so as to fold the two plates of the side panel 13 close to the side of the compartment framework 10.

[0035] The outer side of the side panel 13 on the same side of the compartment framework 10 is connected with an outer side plate 14, and the connection between the outer side plate 14 and the connected side panel 13 is also a rotation connection, and the connection structure between the outer side plate 14 and the connected side panel 13 also adopts a hinge connection structure.

[0036] The upper and lower ends of the outer side plate 14 are provided with a plurality of roller skating mechanisms 15, which facilitate the movement of the outer side plate 14, and the upper and lower sides of the outer side plate 14 are provided with grooves 151 for accommodating the roller skating mechanisms, and the grooves 151 are fixedly provided with mounting frames 152 mounted on the outer side plate 14, and the mounting frames 152 are rotatably provided with pulleys 153 which slide on the bottom plate 11 and the top plate 12 in a horizontal state.

[0037] The roller skating mechanism 15 can be arranged only on the lower side of the outer side plate 14.

[0038] The bottom plate 11 and the top plate 12 are provided with sliding rails corresponding to the pulleys 153, and the pulleys 153 slide in the sliding rails, so that the outer side plate 14 can be more stable and smoothly moved to the outside of the compartment framework 10.

[0039] The side panel 13 and the outer side plate 14 can be provided with a door plate which can be freely opened, so as to meet the different loading and unloading and display needs of users.

[0040] When the expansion structure is in the storage state, the two sides of the compartment framework 10 are respectively from inside to outside: the side panel 13, the outer side plate 14, the bottom plate 11 and the top plate 12. The top plate 12 is arranged at the outermost side, so that when the side panel 13, the outer side plate 14, the bottom plate 11 and the top plate 12 are not fixed and stable during the movement of the vehicle, the top plate 12 is located on the outside and will not be directly opened to both sides, and will maintain a vertical state under the influence of gravity, preventing accidents from occurring.

[0041] After the bottom plate 11 is opened, the outer side plate 13 moves on the bottom plate 11, thereby driving the side panel 13 to move, so as to open the expansion structure from the storage state to the expansion state.

[0042] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
