[0012] The linkage push rod is kept parallel to the first column, so that the driven push rod and the secondary active push rod can move in the vertical direction along the linkage push rod, thereby transmitting the movement of the main push rod, so that the driven rod group pushes the second column to move horizontally.

[0013] In some specific embodiments of the present invention, each group of second support arms includes two mutually intersecting rod bodies, one end of the two rod bodies is rotatably connected to the linkage push rod, and the other end is rotatably connected to the main push rod group or the driven rod group; one rod body in each group of second support arms is rotatably connected to the driven push rod or the secondary active push rod.

[0016] The driven rod group is provided with a third arm which can transmit the motion to the secondary driven push rod, and the secondary driven push rod pushes the second column to move horizontally.

[0017] In some specific embodiments of the present invention, the driven rod group includes two third arms, the two third arms cross each other, the first ends of the two third arms are rotatably connected to the transmission rod group, and the second ends of the two third arms are respectively connected to the two ends of the second column.

[0018] The two third arm transmissions are arranged to make the transmission of the entire telescopic mechanism more stable.

[0019] In the second aspect, an embodiment of the present invention provides a folding car body, comprising: a car body support frame; a car body side panel; a movable panel, the movable panel having a first end and an opposite second end, the first end being rotatably connected to the car body support frame, and the second end being rotatably connected to the car body side panel; the movable panel having a first state in which the second end is contracted to approach the car body support frame; and a second state in which the second end is unfolded to move away from the car body support frame; and a telescopic mechanism as described above, the telescopic mechanism being connected to the car body support frame and the car body side panel; the telescopic mechanism being configured to drive the car body side panel to move so that the movable panel is contracted to the first state or unfolded to the second state.

[0020] The folding carriage is provided with a telescopic mechanism between the carriage support frame and the carriage side panels. Through the extension or contraction of the telescopic mechanism, the carriage side panels can be pushed to move in a direction away from or close to the carriage support frame, thereby driving the movable panels to expand or contract together. In the prior art, when the common carriage is unfolded, a rigid pull rod is used to pull open the carriage floor. During the process of pulling open the carriage floor, the side panels of the carriage move outward. A large initial torque is required when the carriage with this structure is unfolded, and the carriage is very difficult to unfold. In this embodiment, the telescopic mechanism directly drives the carriage side panels to move linearly, and through the linear movement of the carriage side panels, the movable panels are driven to flip open. Therefore, when the carriage is unfolded, a large initial torque is not required, and the carriage can be easily unfolded. The unfolding of the folding carriage is simple and fast.

[0021] In some specific embodiments of the present invention, the telescopic mechanism further includes a driving component, which is transmission-connected to the main push rod group, and the driving component is configured to drive the main push rod group to move up and down along the carriage support frame.

[0022] The driving component generates a power source, thereby driving the connecting rod assembly to move, and then driving the side panels of the carriage to move, so that the movable panels are turned over, thereby realizing the unfolding of the entire folding carriage.

[0023] In some specific embodiments of the present invention, the movable panel includes a first movable panel and a second movable panel, the first movable panel is connected to the top end of the carriage support frame and the carriage side panel; the second movable panel is connected to the bottom end of the carriage support frame and the carriage side panel; the telescopic mechanism is connected to the bottom end of the carriage support frame and the carriage side panel, and is used to drive the carriage side panel to move so that the first movable panel and the second movable panel are contracted to a first state or expanded to a second state.

[0024] The arrangement of the first movable plate and the second movable plate allows the top and bottom of the entire folding carriage to be extended, thereby increasing the internal space of the entire folding carriage and making the application range wider.

[0025] In some specific embodiments of the present invention, the first movable plate and the second movable plate each include two plate bodies, which are symmetrically arranged on both sides of the carriage support frame, and the two ends of each plate body are respectively connected to the carriage support frame and the corresponding side carriage side panel.

[0026] By configuring the first movable panel and the second movable panel as two panels, when the first movable panel and the second movable panel are unfolded, one panel can be unfolded first and then the other half, thus achieving better stability when unfolding the first movable panel and the second movable panel.

[0027] In some specific embodiments of the present invention, the folding carriage further includes a stretching mechanism, which is transmission-connected to the second movable plate and is used to further stretch and unfold the second movable plate in the second state.

[0028] Since the telescopic mechanism is connected to the car body support frame and the bottom end of the car body side panel, when the telescopic mechanism drives the car body side panel to move and drives the first movable panel and the second movable panel to unfold, the second end of the second movable panel arranged on the top of the car body side panel and the connection with the car body side panel may tilt downward. By arranging a stretching mechanism at the second movable panel, the second movable panel can be further unfolded to avoid sagging of the second movable panel.

[0029] In some specific embodiments of the present invention, the stretching mechanism is a hydraulic cylinder stretching mechanism, and the hydraulic cylinder stretching mechanism is arranged at the bottom of the second movable plate.

[0030] By setting a hydraulic cylinder, when the hydraulic cylinder works, it can drive the second movable plate to unfold. At the same time, the hydraulic cylinder can provide support for the second movable plate, thereby ensuring that the second movable plate can tilt downward. Therefore, the unfolding of the second movable plate not only depends on the linkage of the telescopic mechanism, but also includes the action of the hydraulic cylinder, further making the unfolding effect of the second movable plate better.

[0031] In some specific embodiments of the present invention, the first movable panel and the second movable panel each include at least two folding panels hinged in sequence; when the movable panel is in a first state, the multiple folding panels are approximately parallel to the side panels of the vehicle body and close to the vehicle body support frame; when the movable panel is in a second state, the multiple folding panels are unfolded in sequence.

[0032] By configuring the first movable panel and the second movable panel to include at least two folding panels hinged in sequence, the unfolding space of the entire folding compartment can be further increased.

[0033] In some specific embodiments of the present invention, the carriage support frame includes: a base frame; a linear track, which is rotatably connected to the base frame, and when the telescopic mechanism drives the carriage side panels to move, the carriage side panels move along the linear track; a top frame; and a support rod, which is connected between the top frame and the base frame, and is a lifting rod that can drive the top frame to rise and fall.

[0034] By setting the support frame as a lifting rod, the top frame can be raised or lowered through the support frame, so that the height of the entire folding carriage can be adjusted, further increasing the use range of the entire folding carriage. Further, by setting a track on the bottom frame, the side panels of the carriage can move within the track, limiting the trajectory of the movement of the side panels of the carriage, and making the movement of the side panels of the carriage more controllable. In the prior art, since it is necessary to use a hard straight pull rod to pull the bottom plate to unfold, the side panels of the carriage move along the curve of the bottom frame. Therefore, it is necessary to set a curved track on the bottom frame, and the track at the bottom of the curved track carriage must be set to a curved shape, resulting in the processing size being difficult to control, the processing technology being complicated, the structure being poorly stressed after processing, the support being unstable, and being easy to deform. In this embodiment, the telescopic mechanism directly drives the side panels of the carriage to move linearly, and the movable plate is driven to flip and open through the linear movement of the side panels of the carriage. Therefore, when the carriage is unfolded, a large initial torque is not required, and the carriage can be easily unfolded. And because the telescopic mechanism directly drives the side panels of the carriage, there is no need to set a curved track, making the deployment of the carriage more stable and easier to process.

[0035] Further optionally, rollers are provided at the bottom end of the support frame, so that when the side panels of the carriage move in the above-mentioned linear track, the friction resistance can be reduced, thereby further reducing the difficulty of unfolding the carriage.

[0036] In some specific embodiments of the present invention, the folding carriage further comprises an end panel, which is rotatably connected to the side panel of the carriage.

[0037] By arranging the end panels, the whole carriage can be enclosed, thereby meeting the use requirements of some restaurants, accommodations, and temporary buildings. When the folding carriage needs to be used for purposes such as stage performances, the end panels can be omitted, so that the whole folding carriage is in an open state.

[0038] Further optionally, the end panel comprises at least two panel bodies, which are hinged to each other. When in use, one panel body is flipped upwards. When the height of the folding carriage is unfolded higher, the end panel can better adapt to different heights.

[0039] In some specific embodiments of the present invention, the folding carriage further comprises: a staircase device, the staircase device comprises a staircase body and a turning mechanism, the staircase body is connected to the turning mechanism by transmission, and the turning mechanism is connected to the carriage support frame. By providing the staircase device, people can use it conveniently.

[0040] In a third aspect, an embodiment of the present invention provides a cabin vehicle, comprising a folding cabin as described above; and a semi-trailer, the folding cabin being connected to the semi-trailer.

[0041] The compartment vehicle is easy to unfold, simple to operate, highly functional and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] Please refer to Figure 1-Figure 11 The embodiment of the present invention provides a folding carriage 100, which includes a carriage support frame 110, a carriage side panel 120, a movable panel 130 and a telescopic mechanism 140. The movable panel 130 is rotatably connected to the carriage side panel 120 and the carriage support frame 110. The telescopic mechanism 140 is connected to the carriage support frame 110 and the carriage side panel 120.

[0061] The folding carriage 100 is provided with a telescopic mechanism 140 between the carriage support frame 110 and the carriage side panel 120. The telescopic mechanism 140 can push the carriage side panel 120 to move away from or close to the carriage support frame 110 through extension or contraction, thereby driving the movable panel 130 to expand or contract together. During the entire process of unfolding the folding carriage 100, the telescopic mechanism 140 directly drives the carriage side panel 120 to move linearly, and drives the movable panel 130 to flip open through the linear movement of the carriage side panel 120. Therefore, when the carriage is unfolded, a large initial torque is not required, and the carriage can be easily unfolded. The unfolding operation of the folding carriage 100 is simple and fast.

[0062] Specifically, refer to Figure 1-Figure 3The carriage support frame 110 includes a bottom frame 111, a top frame 112, a support rod 113 and a linear track 114. The support rod 113 is connected between the bottom frame 111 and the top frame 112. The support rod 113 is a lifting rod. Therefore, the support rod 113 can raise or lower the position of the top frame 112 relative to the bottom frame 111, thereby meeting the requirements of the spatial height of the folding carriage 100 in different scenarios. Further optionally, the lifting rod includes two sections with different diameters, and the lifting rod at the end with a smaller diameter is inserted into the lifting rod with a larger diameter. Under the action of the driving source, the lifting rod of the smaller diameter moves along the height direction of the folding carriage 100, thereby lifting and lowering the top frame 112. The above-mentioned power source can be selected from hydraulic cylinders, cylinders or linear motors commonly used in the field.

[0063] In other optional embodiments of the present invention, the above-mentioned support rod 113 can also be optionally set as other applicable lifting structures in the field. For example, the support rod 113 is made into a multi-section rod body, and the outer diameter of the multi-section rod body gradually decreases in the direction extending from the bottom frame 111 to the top frame 112. The lifting and lowering is achieved by contracting or pulling out the multi-section rod body.

[0064] In other optional embodiments of the present invention, the support rod 113 may also be configured as a structure that cannot be raised or lowered.

[0065] Furthermore, there are four support rods 113. Two support rods 113 are respectively arranged on both sides of the base frame 111, and are respectively located at the front end and the rear end of the folding carriage 100. The two support rods 113 on both sides are connected to the carriage side panels 120 on the corresponding sides through the movable panels 130, so that the movable panels 130 on both sides of the folding carriage 100 can be separately expanded or retracted.

[0066] Furthermore, the linear track 114 is rotatably connected to both sides of the bottom frame 111. When the entire folding carriage 100 needs to be unfolded, the linear track 114 is first unfolded toward the two carriage side panels 120 to provide support for the subsequent movement of the carriage side panels 120 on the linear track 114. Furthermore, the linear track 114 is rotatably connected to the bottom of the bottom frame 111 through a hinge. After being folded, the linear track 114 is placed at the bottom of the semi-trailer to avoid interference with the tires.

[0067] In the prior art, when the common carriage is unfolded, a rigid pull rod is used to pull the carriage floor open. During the process of pulling the carriage floor open, the side panels of the carriage move outward. This structure requires a large initial torque when the carriage is unfolded, and the carriage is very difficult to unfold. In addition, in this process, the rigid pull rod pulls the floor hard, causing the side panels of the carriage to move along the curve of the chassis. Therefore, it is necessary to set a curved track on the chassis. The processing size of this curved track is not easy to control, the processing technology is complicated, the structure is not well stressed after processing, the support is unstable, and it is easy to deform. In this embodiment, the telescopic mechanism 140 directly drives the carriage side panel 120 to move linearly, and the linear movement of the carriage side panel 120 drives the movable panel 130 to flip open. Therefore, when the carriage is unfolded, a large initial torque is not required, and the carriage can be easily unfolded. And because the telescopic mechanism 140 directly drives the carriage side panel 120, there is no need to set a curved track, making the unfolding of the carriage more stable and easier to process.

[0068] By setting the track as a straight track 114, the problems existing in the prior art are solved, the initial moment of the carriage unfolding is reduced, and the carriage unfolding is made easier.

[0069] It should be noted that the materials of the bottom frame 111, top frame 112, support rod 113 and linear track 114 can be selected from metal materials, alloy materials and other materials with high strength and rigidity commonly used in the art, such as aluminum alloy materials, T960 high-strength rectangular steel pipes, etc.

[0070] Furthermore, a roller 115 is provided at the bottom end of the support rod 113 , so that when the carriage side panel 120 moves in the above-mentioned linear track 114 , the friction resistance can be reduced, and the difficulty of unfolding the carriage is further reduced.

[0071] Further, the movable panel 130 includes a first movable panel 131 and a second movable panel 132, wherein the first movable panel 131 is connected to the top of the carriage support frame 110 and the carriage side panel 120; and the second movable panel 132 is connected to the bottom of the carriage support frame 110 and the carriage side panel 120. Further optionally, the first movable panel 131 and the second movable panel 132 may each include at least two folding panels that are hinged in sequence. When the movable panel 130 is in the first state, the plurality of folding panels are approximately parallel to the carriage side panel 120 and close to the support rod 113; when the movable panel 130 is in the second state, the plurality of folding panels are flipped and unfolded in sequence under the action of the telescopic mechanism 140. By setting the first movable panel 131 and the second movable panel 132 to include at least two folding panels that are hinged in sequence, the unfolding space of the entire folding carriage 100 can be further increased.

[0072] In other optional embodiments of the present invention, the first movable panel 131 and the second movable panel 132 may also be configured to include only one folding panel. When the width requirement of the folding carriage 100 is low, only one folding panel may be configured. It should be understood that in other scenarios, only one folding panel may also be configured according to actual needs.

[0073] Further, refer to Figure 5 Some embodiments of the present invention provide a telescopic mechanism 140, including a main driving rod group 141, at least one transmission rod group 142 and a driven rod group 143. The main driving rod group 141 is used for sliding connection to the first column, and the driven rod group 143 is used for rotation connection to the second column.

[0074] In this embodiment, the first column is the support rod 113, and the second column is the carriage side plate 120. That is, the main push rod group 141 is slidably connected to the support rod 113, and the driven rod group 143 is rotatably connected to the carriage side plate 120. Further, the main push rod group 141 can slide vertically along the support rod 113. Specifically, refer to Figure 4 , sliding in the vertical slideway 1131 provided on the support rod 113. Further, at least one transmission rod group 142 is rotatably connected to the main driving rod group 141. The driven rod group 143 is rotatably connected to the transmission rod group 142, and the carriage side plate 120 can move horizontally under the push of the driven rod group 143.

[0075] Furthermore, the main push rod group 141 includes a main push rod 1411 and at least one first arm 1412, at least one first arm 1412 intersects with the main push rod 1411, and the main push rod 1411 is rotatably connected to at least one first arm 1412; the main push rod 1411 is rotatably connected to the transmission rod group 142, the first end of the first arm 1412 is rotatably connected to the support rod 113, and the second end of the first arm 1412 is rotatably connected to the transmission rod group 142.

[0076] Optionally, the main push rod 1411 is connected to the vertical slideway 1131 of the support rod 113 via a pin shaft, so that it can slide vertically along the support rod 113 .

[0077] Further optionally, the main push rod group 141 includes two first arms 1412, the two first arms 1412 cross each other, the first ends of the two first arms 1412 are respectively rotatably connected to the two ends of the support rod 113, and the second ends of the two first arms 1412 are respectively rotatably connected to the transmission rod group 142.

[0078] By providing two first arms 1412 , the transmission of the entire telescopic mechanism 140 can be made more stable. The number of the first arms 1412 can be selectively set to one or two according to the stability of the entire telescopic mechanism 140 .

[0079] Further, the transmission rod group 142 includes a linkage push rod 1421, a driven push rod 1422, a secondary active push rod 1423 and two groups of second support arms 1424. The driven push rod 1422 is rotatably connected to the main push rod group 141, and the secondary active push rod 1423 is rotatably connected to the driven rod group 143. The vertical slideway of the linkage push rod 1421 is parallel to the vertical slideway 1131 of the support rod 113, and the driven push rod 1422 and the secondary active push rod 1423 are both slidably connected to the linkage push rod 1421. One end of the two groups of second support arms 1424 are both rotatably connected to the linkage push rod 1421, and the other end is respectively rotatably connected to the main push rod group 141 or the driven rod group 143.

[0080] Through the transmission of the above-mentioned first arm 1412, the movement trajectory of the driven push rod 1422 is kept symmetrical with the movement trajectory of the main push rod 1411. The driven push rod 1422 moves vertically in the vertical slideway of the linkage push rod 1421, so that the movement can be transmitted to the driven rod group 143.

[0081] Further optionally, each set of second arms 1424 includes two mutually intersecting rods, one end of each of the two rods is rotatably connected to the linkage push rod 1421, and the other end is rotatably connected to the main push rod group 141 or the driven rod group 143. One rod in each set of second arms 1424 is rotatably connected to the driven push rod 1422 or the secondary active push rod 1423.

[0082] Further, the driven rod group 143 includes at least one third arm 1431 and a secondary driven push rod 1432, and at least one third arm 1431 intersects with the secondary driven push rod 1432. The first ends of the third arm 1431 and the secondary driven push rod 1432 are both rotatably connected to the transmission rod group 142, and the second end of the third arm 1431 is rotatably connected to the carriage side plate 120. The second end of the secondary driven push rod 1432 is rotatably connected to the third arm 1431 or rotatably connected to the carriage side plate 120.

[0083] It should be noted that the second end of the secondary driven push rod 1432 is rotatably connected to the third arm 1431 or rotatably connected to the carriage side plate 120, which is selected according to the stability of the entire telescopic mechanism 140. When the stability is high, the second end of the secondary driven push rod 1432 is rotatably connected to the third arm 1431; when the stability is low, the second end of the secondary driven push rod 1432 is rotatably connected to the third arm 1431 or rotatably connected to the carriage side plate 120.

[0084] Further optionally, the driven rod group 143 includes two third arms 1431, the two third arms 1431 cross each other, the first ends of the two third arms 1431 are both rotatably connected to the transmission rod group 142, and the second ends of the two third arms 1431 are respectively connected to the two ends of the car side panel 120.

[0085] By providing two third arms 1431 , the carriage side panel 120 can be further stably pushed to move, so that the horizontal movement of the entire telescopic mechanism 140 is more stable.

[0086] The rotational connection between the above-mentioned rod groups can be selected to be rotationally connected through hinges, rotating shafts, etc.

[0087] It should be noted that the number of the transmission rod groups 142 can be selectively set according to the actual distance between the support rod 113 and the carriage side plate 120. Of course, the number of the transmission rod groups 142 can also be reduced by changing the length of each rod body. Figure 5-7 , Figure 5 is a structural schematic diagram of the telescopic mechanism 140 when only one transmission rod group 142 is provided; Figure 6 It is a structural schematic diagram of the telescopic mechanism 140 when two transmission rod groups 142 are provided; Figure 7 The schematic diagram of the structure of the telescopic mechanism 140 is shown in FIG. 1 when three transmission rod groups 142 are provided. If more transmission rod groups 142 are required, they can be increased according to the above connection rules.

[0088] Further, refer to Figure 4 The telescopic mechanism 140 further includes a driving component 133, which is connected to the main push rod 1411 and is configured to drive the main push rod 1411 to move up and down along the support rod 113. The driving component 133 may be a hydraulic cylinder, a pneumatic cylinder or a linear motor commonly used in the art.

[0089] Optionally, refer to Figure 4, the driving component 133 is connected to the vertical slide 1131 through the active pin 134, and the active pin 134 is connected to the main push rod 1411. The driving component 133 can be fixedly connected to the support rod 113 by a flange. The movement direction of the driving pin 134 is ensured to be vertical by the movement direction of the driving component 133 and the vertical slide 1131. Through the transmission of the first arm 1412 and the rotating shaft, the movement trajectory of the driven push rod 1422 is kept symmetrical with the movement trajectory of the main push rod 1411. The driven push rod 1422 drives the driven pin to move and moves vertically in the slide of the middle linkage push rod 1421. The driven pin drives the secondary active push rod 1423 to move, and similarly drives the secondary driven push rod 1432 to move. The secondary driven push rod 1432 moves, drives the third arm 1431 and the rotating shaft, and pushes the moving carriage side panel 120 to move horizontally.

[0090] In other embodiments of the present invention, a scissor-type telescopic mechanism can be selected, which includes two groups of connecting rod assemblies, each group of connecting rod assemblies includes a plurality of connecting rods connected in sequence, the two groups of connecting rod assemblies are cross-shaped in a scissor-like manner, and the two connecting rods that cross each other are hinged to each other. The driving component is connected to the connecting rod close to the support rod, so that when the driving component drives the connecting rod close to the support rod to extend, it can drive each subsequent connecting rod to move, thereby unfolding the movable plate 130. The driving component 133 can also be selected from hydraulic cylinders, cylinders or linear motors commonly used in the art. This scissor-type telescopic mechanism can also directly drive the car side panel 120 to move linearly, and through the linear movement of the car side panel 120, the movable plate 130 is driven to flip open, so when the car is unfolded, a large initial torque is not required, and the car can be easily unfolded.

[0091] It should be noted that, in this embodiment, when the driving source is a hydraulic cylinder, an upper limit valve is connected in series on the hydraulic pipeline, and the limit valve is pneumatically controlled and takes air from the air tank of the semi-trailer. When the movable plate 130 flips to the specified position, the limit valve is pressed and the oil circuit is disconnected, so as to achieve the controllability of the flipping positioning size of the movable plate 130. Further, optionally, the manual operation valve of the hydraulic pipeline is changed to an electrically controlled distribution valve to improve the controllability of the hydraulic system.

[0092] Further, in other optional embodiments of the present invention, referring to Figure 3, a stretching mechanism 150 is also provided at the bottom of the second movable panel 132, which is used to further stretch and unfold the second movable panel 132 in the second state. Since the telescopic mechanism 140 is connected to the bottom end of the carriage support frame 110 and the carriage side panel 120, when the telescopic mechanism 140 drives the carriage side panel 120 to move, driving the first movable panel 131 and the second movable panel 132 to unfold, the second end of the second movable panel 132 set at the top of the carriage side panel 120 and the connection with the carriage side panel 120 may tilt downward. By providing the stretching mechanism 150 at the second movable panel 132, the second movable panel 132 can be further unfolded to avoid the second movable panel 132 from sagging. Further optionally, the above-mentioned stretching mechanism 150 is selected as a hydraulic cylinder, which is installed at the bottom of the second movable panel 132 and is connected to the second movable panel 132 by transmission. By providing the hydraulic cylinder, when the hydraulic cylinder works, it can drive the second movable panel 132 to unfold. At the same time, the hydraulic cylinder can provide support for the second movable panel 132, so as to ensure that the second movable panel 132 can tilt downward. Therefore, the deployment of the second movable panel 132 is not only dependent on the linkage of the telescopic mechanism 140, but also includes the action of the hydraulic cylinder, which further makes the deployment effect of the second movable panel 132 better. Further optionally, at least one hydraulic cylinder is provided at the bottom of each folding plate of the second movable panel 132, so as to further stably support the second movable panel 132 and ensure that the second movable panel 132 is stably deployed.

[0093] A stretching mechanism 150 is also provided at the bottom of the second movable panel 132 so that the entire folding carriage 100 can be better unfolded, and can be better applied to the semi-open folding carriage 100 for stage performances.

[0094] Further, refer to Figure 8 and Fig. 9 When the folding carriage 100 needs to be used for restaurants, accommodation, temporary buildings and other closed use requirements, end panels 160 can be set at the front and rear ends of the folding carriage 100. Specifically, the end panels 160 are rotatably connected to the carriage side panels 120 through hinges.

[0095] When the carriage is unfolded, the end panel 160 is rotated to the front or rear end of the carriage in a direction perpendicular to the carriage side panel 120, so that the carriage is closed. Further optionally, the front and rear ends of the two carriage side panels 120 are connected to an end panel 160, so that the front and rear ends of the entire folding carriage 100 are closed by the cooperation of the two end panels 160. Further optionally, each of the above-mentioned end panels 160 includes at least two panel bodies 161, and the two panel bodies 161 are hinged to each other. Further, a driving member 162 is also provided at the hinge connection, and the driving member 162 drives the top panel body 161 to flip. When in use, a panel body 161 is flipped upwards, and when the height of the folding carriage 100 is unfolded higher, this end panel 160 can better adapt to different heights. The above-mentioned driving member 162 can select a driving member such as a hydraulic cylinder.

[0096] It should be noted that when the folding carriage 100 is used for stage performances and the like, the end panel 160 may not be provided.

[0097] In other optional embodiments of the present invention, an independent compartment is designed at the front of the folding compartment 100. Optionally, the compartment is 2500-2600 mm wide, 700-900 mm long, and 2100-2300 mm high. A silent diesel generator set is installed at the bottom of the compartment, and the upper space is used to install electrical equipment such as air conditioners, so that the entire folding compartment 100 is more functional.

[0098] The steps of unfolding the folding carriage 100 are as follows: first, unfold and support the linear rails 114 on both sides of the bottom frame 111. Then lift the top frame 112. The top frame 112 drives the first movable panel 131 to a semi-expanded state. The telescopic mechanism 140 is activated to push the carriage side panel 120 outward. When the carriage side panel 120 moves, it drives the first movable panel 131 and the second movable panel 132 to flip and move, so as to unfold the carriage.

[0099] In other optional embodiments of the present invention, only one compartment side panel 120 may be provided, and correspondingly only one side movable panel 130 may be provided. This folding compartment 100 may be used in some specific usage scenarios, for example, when a larger compartment space is not required, this form may be selected.

[0100] Alternatively, see Fig.10 and Fig.11 The folding carriage 100 further includes a stair device 170 . The stair device 170 includes a stair body 171 and a turnover mechanism 172 . The stair body 171 is transmission-connected to the turnover mechanism 172 , and the turnover mechanism 172 is connected to the carriage support frame 110 .

[0101] Further, the turning mechanism 172 selects a hydraulic cylinder.
