The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] Please see Figures 1 to 6 In one embodiment, a folding compartment includes a body 1, a compartment frame 4 and an extended compartment 24, wherein the compartment frame 4 is arranged on the body 1, and a top plate 3 is arranged on the upper part of the compartment frame 4, and a bottom plate 2 is arranged on the lower part; the extended compartment 24 includes a first support assembly 9, a second support assembly 17, a first extension assembly 21 and a second extension assembly 12, the first support assembly 9 is slidably connected to the bottom plate 2, the second support assembly 17 is hinged to the top plate 3, and the first support assembly 9 is slidably connected to the second support assembly 17; the first extension assembly 21 is rotatably connected to the bottom plate 2, and the second extension assembly 12 is slidably connected to the top plate 3.

[0026] The vehicle body 1 is provided with a motor and an engine and other devices to provide driving force for the folding compartment. The compartment frame 4 is detachably connected to the vehicle body 1, which is convenient for the maintenance of the equipment of the dining car. The extended compartment 24 can be received in the compartment frame 4. The first support assembly 9 is slidably connected to the bottom plate 2 to ensure that the first support assembly 9 can extend outward. The hinge of the second support assembly 17 and the top plate 3 ensures that the second support assembly 17 can rotate around the hinge. The matching connection between the first support assembly 9 and the second support assembly 17 ensures that when the first support assembly 9 extends outward, the second support assembly 17 can simultaneously rotate upward and unfold.

[0027] When unfolding, the first support assembly 9 slides outward from the inside of the vehicle frame and unfolds, while the second support assembly 17 rotates around the hinged portion from a vertical position to a horizontal position.

[0028] The above-mentioned folding compartment can achieve the following technical effects: the second support assembly 17 is unfolded while the first support assembly 9 is unfolded, and two support assemblies are unfolded at the same time by using a power drive device, which reduces the number of drive devices and also improves the unfolding speed of the folding compartment extension compartment 24, and provides sufficient support for the unfolding of the second support assembly 17, thereby improving stability.

[0029] In addition, this application also provides some more specific implementations to improve the above device.

[0030] Furthermore, in order to expand the usable area of ​​the folding compartment, the first expansion component 21 includes a bottom expansion plate 19 and a hydraulic rod 20, the bottom expansion plate 19 is hinged to one side of the bottom plate 2, the hydraulic rod 20 is arranged at the bottom of the bottom plate 2 and connected to the bottom expansion plate 19, and the hydraulic rod 20 is used to drive the bottom expansion plate 19 to rotate around the hinged portion in the range of 0° to 90°.

[0031] Specifically, the bottom expansion plate 19 is hinged to the bottom plate 2 and connected to the hydraulic rod 20. When the hydraulic rod 20 is extended and retracted, the bottom expansion plate 19 can be pulled to rotate around the hinged portion with the bottom plate 2 within a range of 0° to 90°. When the bottom expansion plate 19 rotates 90° to a horizontal position and is in the same horizontal plane with the bottom plate 2, it is clamped on the boss 23 provided on the first support assembly 9 to form a stable platform, thereby expanding the use area of ​​the folding compartment; when closing the compartment, the bottom expansion plate 19 rotates 90° from the horizontal position to the vertical position, and the bottom expansion plate 19 is retracted.

[0032] When the first support assembly 9 stops sliding outward, the hydraulic rod 20 starts to perform telescopic movement, and while performing the telescopic movement, the hydraulic rod pulls the bottom expansion plate 19 to rotate around the hinged portion from the vertical position to the horizontal position.

[0033] Furthermore, the first supporting assembly 9 includes a slide 6 and a supporting frame 7 , the lower end of the supporting frame 7 is sleeved in the slide 6 , and the slide 6 is slidably connected to the base plate 2 .

[0034] Specifically, a slide rail 5 is provided on the bottom plate 2, and a slide cylinder 6 is slidably matched with the slide rail 5 and driven to slide by a driving device. The lower end of the support frame 7 is sleeved in the slide cylinder 6 and can be extended and retracted in the slide cylinder 6 under the drive of the driving device. The above-mentioned driving device can be a hydraulic rod or a motor, etc. When the first support assembly 9 slides outward, the driving device first drives the slide cylinder 6 to slide outward along the slide rail 5. When the slide cylinder 6 slides to the outermost side, the support frame 7 extends from the slide cylinder 6 to fully unfold the first support assembly 9. In addition, a pulley 22 is provided on one side of the bottom plate 2, which can provide support for the slide cylinder 6 while improving the sliding property of the slide cylinder 6, ensuring that the slide cylinder 6 still has sufficient stability when it slides to the outermost side.

[0035] When the first support assembly 9 is fully deployed, the slide 6 first slides outwards. After the slide 6 stops sliding, the support frame 7 begins to extend outwards from the inside of the slide 6.

[0036] Furthermore, in order to improve the stability of the bottom expansion plate 19 after it is unfolded, a boss 23 is provided on one side of the support frame 7 , and the boss 23 is used to clamp the bottom expansion plate 19 .

[0037] Specifically, when the bottom expansion plate 19 rotates to a horizontal position under the pull of the hydraulic rod 20, the bottom expansion plate 19 is jointly supported by the support frame 7 and the boss 23, and the bottom expansion plate 19 is clamped and fixed to ensure that the bottom expansion plate 19 has sufficient stability after being unfolded.

[0038] After the first support assembly 9 is fully deployed, the bottom expansion plate 19 rotates from a vertical position to a horizontal position as the hydraulic rod 20 is extended and retracted, and is located in the same plane as the bottom expansion plate 19 and contacts the boss 23 .

[0039] Furthermore, in order to reduce the difficulty of unfolding the first support assembly 9 and the second support assembly 17 and to increase the unfolding speed of the expansion compartment 24, the first support assembly 9 further includes a roller 8, which is mounted on the top of the support frame 7. The cooperation between the roller 8 and the slide bar 18 can reduce the wear between the first support assembly 9 and the second support assembly 17 and increase the service life of the folding compartment. The second support assembly 17 includes a top support frame 15, and a slide bar 18 is provided on one side of the top support frame 15, and the slide bar 18 is connected with the roller 8.

[0040] Specifically, the roller 8 is mounted on the top of the support frame 7 and can rotate. The slide bar 18 cooperates with the roller 8 arranged on the top of the support frame 7, so that the roller 8 can roll along the slide bar 18, ensuring that the top support frame 15 can flip upward. In addition, the cooperation between the roller 8 and the slide bar 18 improves the sliding property, reduces the wear of the top support frame 15 and the support frame 7, and increases their service life.

[0041] When the support frame 7 slides outward, the roller 8 starts to roll along the slide rod 18, and at the same time, the top support frame 15 rotates upward from the vertical position to the horizontal position.

[0042] Furthermore, in order to increase the area of ​​the top, the second expansion component 12 includes a first top expansion plate 10 and a second top expansion plate 11, the first top expansion plate 10 is slidably connected to the top plate 3, a T-shaped slide groove 13 is provided on one side of the first top expansion plate 10, and the second top expansion plate 11 is slidably connected to the T-shaped slide groove 13.

[0043] Specifically, a T-shaped slide groove 13 is provided on one side of the first top expansion board 10, and the second top expansion board 11 is also provided in a T shape and installed in the T-shaped slide groove 13. When the first top expansion board 10 slides to the outermost side along the slide groove 14, the driving device in the T-shaped slide groove 13 provided on the first top expansion board 10 can drive the second top expansion board 11 to slide outward in the T-shaped slide groove 13, further unfolding the second expansion assembly 12 and increasing the top area, wherein the driving device can be a motor or a hydraulic device, etc. The T-shaped slide groove 13 is provided in a T shape to stably store the second top expansion board 11 in the first top expansion board 10.

[0044] When the second expansion component 12 is unfolded, the first top expansion plate 10 first slides outward along the slide groove 14. When the first top expansion plate 10 slides outward to the outermost side, the second top expansion plate 11 starts to slide outward along the T-shaped slide groove until it is fully unfolded.

[0045] In another embodiment, in order to unfold the expansion compartment 24 faster, the difference from the above embodiment is that the first support assembly 9 also includes a telescopic rocker 16, and an axis is provided on one side of the support frame 7 and the first top expansion plate 10, and one end of the telescopic rocker 16 is sleeved on the axis on one side of the first top expansion plate 10, and the other end is sleeved on the axis on one side of the support frame 7.

[0046] Specifically, when the first support assembly 9 is extended outward, the second support assembly 17 can be rotated upward and extended at the same time. At the same time, due to the connection between the telescopic rocker 16, the first top extension plate 10 and the support frame 7, when the first support assembly 9 is extended outward, the first top extension plate 10 is pulled outward by the telescopic rocker 16. This embodiment can simultaneously unfold multiple components, can better improve the unfolding speed, reduce the number of driving devices, and improve the unfolding efficiency of the folding compartment.

[0047] When the first support assembly 9 extends outward, the second support assembly 17 rotates upward and unfolds at the same time, and the telescopic rocker 16 begins to extend and retract. As the telescopic rocker 16 extends and retracts, the first top expansion plate 10 slides outward along the slide slot 14 at the same time.

[0048] In order to reduce the energy consumption of the folding cabin, a driving power source is provided in the vehicle body 1, and solar photovoltaic panels are provided on the top of the first top expansion plate 10 and the second top expansion plate 11, and the solar photovoltaic panels are electrically connected to the driving power source. The solar photovoltaic panels are provided on the top of the first top expansion plate 10 and the second top expansion plate 11, which can not only provide a shielding effect, but also make full use of the top area. The solar photovoltaic panels provide a certain amount of kinetic energy for the folding cabin, and can also be used as energy for other components of the folding cabin, thereby reducing the energy consumption and use cost of the folding cabin.

[0049] During the unfolding process of the expansion car 24, first, the slide 6 drives the support frame 7 to slide outward from the car frame 4 along the slide rail 5. When the slide 6 slides to the outermost side, the support frame 7 extends outward from the inside of the slide; while the second support assembly 17 slides outward and unfolds, the roller 8 arranged on the top of the support frame 7 begins to roll along the slide rod 18, so that the top support frame 15 rotates upward from the vertical position to the horizontal position around the hinged part under the support of the support frame 7; at the same time, the telescopic rocker 16 begins to perform telescopic movement, driving the first top expansion plate 10 to slide outward along the slide groove 14. When the first top expansion plate 10 slides to the outermost side, the second top expansion plate 11 extends outward along the T-shaped slide groove until it is fully unfolded. After that, the hydraulic rod 20 begins to perform telescopic movement, pulling the bottom expansion plate 19 to rotate around the hinged part from the vertical position to contact with the boss 23. At this point, the expansion car 24 is fully unfolded.

[0050] Through the above implementation, the folding compartment in the embodiment can achieve at least the following technical effects:

[0051] By cooperating with the first support assembly 9 and the second support assembly 17, the second support assembly 17 is unfolded while the first support assembly 9 is unfolded, thereby improving the unfolding efficiency of the folding cabin extension compartment 24; by cooperating with the first support assembly 9 and the first extension assembly 21, the effective use area of ​​the folding cabin is increased; by cooperating with the second support assembly 17 and the second extension assembly 12, the area of ​​the top of the folding cabin is increased, and the shielding area of ​​the folding cabin is increased; by cooperating with the first support assembly 9 and the second support assembly 17, the stability of the top is improved; by setting the second extension assembly 12 as a solar photovoltaic panel, the energy consumption of the folding cabin is reduced, and the environmental protection performance of the folding cabin is improved.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
