[0069] It should be noted that before the user tows the trailer caravan 100 on the road, the compartment 10 can be switched to the stowed state, thereby facilitating the transportation of the trailer caravan 100 and avoiding occupying too much space on the road. When the user tows the trailer caravan 100 to the campsite, the compartment 10 can be switched to the unfolded state, thereby increasing the living space required by the user for camping in the wild.

[0070] exist Figure 1 In the embodiment shown, the carriage 10 is in an unfolded state. Figure 2 In the illustrated embodiment, the carriage 10 is in the stowed state at this time.

[0071] The carriage 10 may be provided with a control system (not shown), and the control system may control the driving assembly 32 to drive the first carriage 14 and the second carriage 16 to move relative to the body 12 according to the user's instructions, so that the carriage 10 switches between the stowed state and the deployed state. It is understood that in other embodiments, the user may also manually pull the first carriage 14 and the second carriage 16, so that the carriage 10 switches between the stowed state and the deployed state.

[0072] Please combine Figures 1 to 3 , Fig.19 In some embodiments, the trailer 100 includes a controller 218, and the controller 218 is electrically connected to the drive assembly 32. The controller 218 is configured to control the drive assembly 32 to drive the first body 14 and the second body 16 to move according to the switching instruction when receiving the switching instruction, so that the car body 10 switches between the storage state and the deployment state.

[0073] In this way, the controller 218 can be used to switch the compartment 10 between the stowed state and the unfolded state, so that when the compartment 10 is in the unfolded state, the spatial volume of the compartment 10 is increased, thereby meeting the user's living space, facilitating operation, and improving user experience.

[0074] Specifically, the controller 218 may be disposed on the body 12, and the controller 218 may be electrically connected to the drive assembly 32. In one embodiment, the user may input a switching instruction, the controller 218 may receive the switching instruction, and the controller 218 may control the drive assembly 32 to drive the first carriage 14 and the second carriage 16 to move according to the switching instruction, so that the first carriage 14 may move along the first direction on the left side close to the body 12, and the second carriage 16 may move along the first direction on the right side close to the body 12, so that the carriage 10 switches between the storage state and the unfolded state. When the carriage 10 is in the unfolded state, the space volume of the carriage 10 increases, thereby meeting the user's living space, convenient operation, and improving user experience.

[0075] It should be noted that before the user tows the trailer caravan 100 on the road, the user can input a command to switch the carriage 1010 to the storage state, thereby facilitating the transportation of the trailer caravan 100 and avoiding occupying too much space on the road. When the user tows the trailer caravan 100 to the campsite, the user can input a command to switch the carriage 1010 to the deployment state, thereby increasing the living space required by the user for camping in the wild.

When the user presses the switch button 222 again, the switch button 222 may be reset from the final position to the initial position. At this time, the switch button 222 is triggered to generate a second switching instruction. The controller 218 may control the drive assembly 32 to drive the first body 14 and the second body 16 to move according to the second switching instruction, so that the carriage 10 switches to the stored state.

[0079] Further, in Fig.13 In the embodiment, the switch button 222 can also be a switch operated by a high-low method. The switch button 222 can be installed on the side of the body 12. The switch button 222 may include a first end 224 and a second end 226. In one embodiment, compared to the side of the body 12, when the user presses the switch button 222 to make the height of the first end 224 lower than the height of the second end 226, the switch button 222 is triggered to generate a first switching instruction, and the controller 218 can control the drive assembly 32 to drive the first body 14 and the second body 16 to move according to the first switching instruction, so that the carriage 10 switches to the unfolded state. When the user presses the switch button 222 to make the height of the second end 226 lower than the height of the first end 224, the switch button 222 is triggered to generate a second switching instruction, and the controller 218 can control the drive assembly 32 to drive the first body 14 and the second body 16 to move according to the second switching instruction, so that the carriage 10 switches to the stored state.

[0080] It can be understood that in other embodiments, the first switching instruction may also be an instruction to store the carriage 10, and the second switching instruction may also be an instruction to unfold the carriage 10.

[0081] Optionally, the switching instruction comes from a terminal device (not shown) that is in communication connection with the controller 218. In this way, the convenience can be further improved.

[0082] Specifically, the terminal device may include a mobile device such as a mobile phone or a tablet computer. The terminal device may be installed with software for controlling the trailer 100.

Since the carriage 10 can be pre-set with a carriage deployment sequence, the controller 218 can control the driving assembly 32 to first drive the first carriage 14 away from the body 12 to move to the first deployment position, and then drive the second carriage 16 away from the body 12 to move to the second deployment position, so that the carriage 10 switches to the deployed state (such as Figure 1 ). It is understandable that in other embodiments, the second body 16 may be first driven to move away from the main body 12 to the second deployed position, and then the first body 14 may be driven to move away from the main body 12 to the first deployed position.

[0084] In addition, in the stowed state, the user can input a switching instruction, and the controller 218 can receive the switching instruction. The controller 218 can control the drive component 32 according to the switching instruction to simultaneously drive the first body 14 away from the main body 12 to the first expanded position and drive the second body 16 away from the main body 12 to the second expanded position, thereby switching the car 10 to the expanded state.

[0085] Optionally, in Figure 1 In the unfolded state, the user can input a switching command, and the controller 218 can receive the switching command. Since the carriage 10 can be pre-set with a storage order of the carriages, the controller 218 can control the driving assembly 32 to first drive the first carriage 14 to move close to the body 12 to the first storage position, and then drive the second carriage 16 to move close to the body 12 to the second storage position according to the switching command, so that the carriage 10 is switched to the storage state (such as Figure 2 ). It is understandable that in other embodiments, the second body 16 may be first driven to move close to the body 12 to the second storage position, and then the first body 14 may be driven to move close to the body 12 to the first storage position.

[0086] In addition, in the expanded state, the user can input a switching instruction, and the controller 218 can receive the switching instruction. The controller 218 can control the driving component 32 according to the switching instruction to simultaneously drive the first body 14 to move close to the main body 12 to the first storage position and drive the second body 16 to move close to the main body 12 to the second storage position, thereby switching the car 10 to the storage state.

[0087] exist Figure 1 In the example, the first deployment position may be represented by S1, and the second deployment position may be represented by S2. Figure 2 In the embodiment, the first storage position can be represented by K1 and the second storage position can be represented by K2.

The two first movable panels 124 may be slidably connected, so that in the unfolded state, the two first movable panels 124 may be slidably spread out along the first direction. It can be understood that when the third solar panel 120 is provided with six or more first movable panels 124, the same can be applied. The height direction H of the carriage 10 includes the up and down direction. The fixed panel 122 and the first movable panel 124 are solar panels capable of converting light energy into electrical energy.

[0147] Optionally, combine Fig.15 The third solar panel 120 further includes a second movable panel 126, which is movably connected to the fixed panel 122. In the stored state, the fixed panel 122 and the second movable panel 126 are stacked. In the unfolded state, the second movable panel 126 is located on one side of the fixed panel 122 along the second direction. In this way, the area of ​​the solar panel 63 can be further increased, and the efficiency of converting solar energy into electrical energy can be improved.

[0148] Specifically, in one embodiment, in the stowed state, the second movable panel 126 can be movably connected to the bottom of the fixed panel 122, and the first movable panel 124 can be movably connected to the top of the fixed panel 122, and the stacking order from top to bottom can be the first movable panel 124, the fixed panel 122, and the second movable panel 126. In one embodiment, in the unfolded state, the second movable panel 126 can be located at the rear side of the fixed panel 122, which can further increase the area of ​​the solar panel 63 and improve the efficiency of converting solar energy into electrical energy.

[0149] In addition, along the H direction, the first movable panel 124 may be located above the fixed panel 122, and the second movable panel 126 may be located below the fixed panel 122; or the first movable panel 124 is located above the second movable panel 126, and the second movable panel 126 is located above the fixed panel 122; or the first movable panel 124 and the second movable panel 126 are located above the fixed panel 122, and the first movable panel 124 and the second movable panel 126 are located in the same plane. The second movable panel 126 is a solar panel 63 capable of converting light energy into electrical energy.

[0150] Optionally, combine Fig.15 and Fig.16 A sliding structure 132 is provided between the fixed plate 122 and the first movable plate 124 and between the fixed plate 122 and the second movable plate 126. The sliding structure 132 includes at least one track 134 and a first opening and closing actuator (not shown). At least one track 134 is provided on the fixed plate 122, and the first movable plate 124 and the second movable plate 126 are provided on at least one track 134. The first opening and closing actuator is configured to drive the first movable plate 124 and the second movable plate 126 to slide on the track 134 so that the third solar panel 120 switches between the first expanded state and the first folded state.

[0151] In this way, the fixed plate 122 and the first movable plate 124 as well as the fixed plate 122 and the second movable plate 126 can be slidably extended or retracted, which is convenient and practical.

[0152] Specifically, in Fig.16 In the embodiment, the fixed plate 122 and the first movable plate 124 are taken as an example. In one embodiment, the sliding structure 132 includes at least one track 134, and may also include a pulley that slides with the track 134, so that the first movable plate 124 slides on the fixed plate 122 to be relatively unfolded, thereby ensuring the acquisition of solar energy and the safe driving of the trailer RV 100.

[0153] At least one track 134 is provided on the fixed plate 122. In the case of camping, the first movable plate 124 can be slid and unfolded with the fixed plate 122 through the sliding structure 132, so that the third solar panel 120 can be switched from the first folded state to the first unfolded state, thereby ensuring the outdoor power supply.

[0154] At least one track 134 is provided on the fixed plate 122. During driving, the first movable plate 124 is slidably retracted with the fixed plate 122 through the sliding structure 132, so that the third solar panel 120 is switched from the first deployed state to the first retracted state, thereby ensuring driving safety. It can be understood that the way the fixed plate 122 is connected to the second movable plate 126 through the sliding structure 132 is consistent with the way the fixed plate 122 is connected to the first movable plate 124 through the sliding structure 132.

[0155] Similarly, a sliding structure 132 is provided between the fixed plate 122 and the second movable plate 126, and the sliding connection method of the second movable plate 126 and the fixed plate 122 through the sliding structure 132 can refer to the sliding connection method of the fixed plate 122 and the first movable plate 124. In addition, a sliding structure 132 is provided between the fixed plate 122 and the first movable plate 124, and a sliding structure 132 is provided between the fixed plate 122 and the second movable plate 126, and the relative sliding of the first movable plate 124 and the fixed plate 122 does not interfere with the relative sliding of the second movable plate 126 and the fixed plate 122.

[0156] That is, the first opening and closing actuator is electrically connected to the third solar panel 120 and can be used to drive the first movable panel 124 and the second movable panel 126 to slide on the track 134, so as to control the third solar panel 120 to switch between the first extended state and the first retracted state.

[0157] The first opening and closing actuator may include a motor. The motor has a gear structure, and the first movable plate 124 has a rack structure. The motor drives the gear to rotate, so that the rack and the first movable plate 124 slide along the track 134 together, thereby controlling the third solar panel 120 to switch between the first extended state and the first retracted state.

[0158] Furthermore, the first opening and closing actuator can also control the degree of expansion and contraction of the third solar panel 120. For example, when there is an obstacle near the trailer 100 and the third solar panel 120 cannot be fully expanded, the first opening and closing actuator can control the sliding distance of the third solar panel 120 on the track 134 to partially expand the third solar panel 120 to avoid collision with the obstacle.

[0159] Optionally, combine Fig.15 and Fig.17A planar rotating structure 136 is provided between the fixed plate 122 and the first movable plate 124 and between the fixed plate 122 and the second movable plate 126. The planar rotating structure 136 includes a rotating shaft 138 and a second opening and closing actuator (not shown). The rotating shaft 138 is provided on the fixed plate 122. The first movable plate 124 and the second movable plate 126 are installed on the rotating shaft 138. The second opening and closing actuator is configured to drive the first movable plate 124 and the second movable plate 126 to rotate in a plane around the rotating shaft 138 so that the third solar panel 120 can switch between the first expanded state and the first folded state.

[0160] In this way, the fixed plate 122 and the first movable plate 124 as well as the fixed plate 122 and the second movable plate 126 can be unfolded or folded through the planar rotating structure 136 , which is convenient and practical.

[0161] Specifically, in Fig.17 In the figure, the planar rotating structure 136 includes a rotating shaft 138 to connect the fixed plate 122 and the first movable plate 124, so that one first movable plate 124 rotates on the fixed plate 122 along the plane R5 direction around the rotating shaft 138 close to the left side of the fixed plate 122 to be relatively unfolded, and the other first movable plate 124 rotates on the fixed plate 122 along the plane R4 direction around the rotating shaft 138 close to the right side of the fixed plate 122 to be relatively unfolded, and the second movable plate 126 rotates on the fixed plate 122 along the plane R3 direction around the rotating shaft 138 close to the rear side of the fixed plate 122 to be relatively unfolded, thereby ensuring the acquisition of solar energy and the safe driving of the trailer RV 100.

[0162] It should be noted that the R4 direction includes the clockwise direction, the R5 direction includes the counterclockwise direction, and the R3 direction includes the counterclockwise direction. In other embodiments, the rotation directions of the first movable plate 124 and the second movable plate 126 around the rotation axis 138 can also be set according to specific circumstances and are not limited to the above rotation directions.

[0163] It can be understood that a rotating shaft 138 is provided on the fixed plate 122. In the case of camping, the first movable plate 124 and the second movable plate 126 can be rotated and unfolded in a plane with the fixed plate 122 through the plane rotating structure 136, so that the third solar panel 120 can be switched from the first folded state to the first unfolded state, thereby ensuring the outdoor power supply.

[0164] A rotating shaft 138 is provided on the fixed plate 122. During driving, the first movable plate 124 and the second movable plate 126 are rotated and folded with the fixed plate 122 through the planar rotating structure 136, so that the third solar panel 120 switches from the first unfolded state to the first folded state, thereby ensuring driving safety.

[0165] That is, the second opening and closing actuator (not shown) may include a motor and be electrically connected to the third solar panel 120, which can be used to drive the first movable panel 124 and the second movable panel 126 to rotate around the rotation axis 138 plane, thereby controlling the third solar panel 12020 to switch between the first expanded state and the first folded state.

[0166] Optionally, combine Fig.15 and Fig.18 A flip structure 140 is provided between the fixed plate 122 and the first movable plate 124 and between the fixed plate 122 and the second movable plate 126. The flip structure 140 includes a flip axis 142 and a third opening and closing actuator (not shown). The flip axis 142 is provided on a side edge of one of the fixed plate 122 and the first movable plate 124, and the other of the fixed plate 122 and the first movable plate 124 is provided with an axis hole (not shown), and is provided on a side edge of one of the fixed plate 122 and the second movable plate 126, and the other of the fixed plate 122 and the second movable plate 126 is provided with an axis hole. The flip axis 142 can rotatably pass through the axis hole. The third opening and closing actuator is configured to drive the first movable plate 124 and the second movable plate 126 to flip around the flip axis 142 to switch the third solar panel 120 between the first expanded state and the first retracted state.

[0167] In this way, the fixed plate 122 and the first movable plate 124 as well as the fixed plate 122 and the second movable plate 126 can be unfolded or folded through the flip structure 140 , which is convenient and practical.

[0168] Specifically, in Fig.18 In the embodiment, the flip structure 140 includes a flip axis 142, and the flip axis 142 includes a first flip axis 144 and a second flip axis 146. The first flip axis 144 connects one side of the fixed plate 122 and one side of the first movable plate 124, so that the first movable plate 124 flips along the first flip axis 144 on the fixed plate 122 to be relatively unfolded. The second flip axis 146 connects one side of the fixed plate 122 and one side of the second movable plate 126, so that the second movable plate 126 flips along the second flip axis 146 on the fixed plate 122 to be relatively unfolded. The flip angle can be 180 degrees, so as to ensure the acquisition of solar energy and the safe driving of the trailer 100. The first movable plate 124 rotates around the flip direction V1 of the first flip axis 144, and the second movable plate 126 rotates around the flip direction V2 of the second flip axis 146.

[0169] It can be understood that the fixed plate 122 can be provided with an axis hole (not shown) so that the flip axis 142 and the axis hole can be connected in a cooperative manner. In the case of camping, the first movable plate 124 and the second movable plate 126 can be spatially flipped and unfolded with the fixed plate 122 through the flip structure 140, so that the third solar panel 120 can be switched from the first folded state to the first unfolded state, thereby ensuring the outdoor power supply.

[0170] The fixed plate 122 is provided with an axis hole (not shown) so that the flip axis 142 and the axis hole are matched and connected. During driving, the first movable plate 124 and the second movable plate 126 are flipped and folded together with the fixed plate 122 through the flip structure 140, so that the third solar panel 120 is switched from the first unfolded state to the first folded state, thereby ensuring driving safety.

[0171] That is, the third opening and closing actuator (not shown) may include a motor and be electrically connected to the third solar panel 120, which can be used to drive the first movable panel 124 and the second movable panel 126 to perform spatial flipping around the flip axis 142, thereby controlling the third solar panel 120 to switch between the first unfolded state and the first folded state.

[0172] In other embodiments, the first movable plate 124 and the second movable plate 126 may also be provided with shaft holes (not shown), and the fixed plate 122 is provided with a flip shaft 142 so that the flip shaft 142 and the shaft holes are matched and connected, and no specific limitation is made here.

[0173] It should be noted that the third compartment 118 can also be moved relative to the body 12 through the cooperation of the motor, the gear and the rack, the slider and the slide slot.

[0174] Please refer to Figure 1 and Fig.19 A vehicle 300 according to an embodiment of the present utility model includes a tractor 102 and a trailer caravan 100 according to any one of the above embodiments.

[0175] In the above-mentioned vehicle 300, by moving the first body 14 and the second body 16 relative to the main body 12, the compartment 10 is switched between the stowed state and the deployed state, so that when the compartment 10 is in the deployed state, the spatial volume of the compartment 10 is increased, thereby meeting more life needs of the user and improving the user experience.
