For example, when the lever 21 is pulled forward, the lever generates a force obliquely upward to the fixed block 41, and the force deforms the fixed block 41 to extend toward the lever 21, so that the strain gauges on the top and bottom surfaces of the fixed block 41 are deformed to extend toward the lever 21, and the generated signals are sent to the control circuit 222, which can determine the forward pulling operation by the operator, thereby driving the wheels 13 to move forward and realizing the forward movement of the vehicle body.

Similarly, when the operation lever 21 is pushed backward, it generates a downward force on the fixed block 41, and the force causes the fixed block 41 to deform downward, so that the strain gauges on the top and bottom surfaces of the fixed block 41 deform downward, and the generated signals are sent to the control circuit 222, which can determine the operation of pushing backward by the operator, so as to drive the wheel 13 to move backward or travel at a preset speed, specifically, when traveling on a flat road, the control circuit drives the wheel 13 to move backward after determining the operation of pushing backward by the operator; when the vehicle runs on a flat road or a downhill, the control circuit controls the wheels 13 to run at a preset speed after judging the backward operation of the operator, so as to realize speed control and avoid the wheels 13 from colliding with the operator during the downhill.

Further, the sensors 43 may be fixedly attached to both sides in the width direction of the fixing block 41, and the deformation of the fixing block 41 in the width direction may be detected by the sensors on the sides in the width direction, thereby determining the operations of the left turn and the right turn.

The present application also provides a camping car 5. Referring to fig. 16-18, fig. 16 is a schematic structural diagram of a camping car according to an embodiment of the present disclosure; FIG. 17 is a schematic view of the camper of FIG. 16 in an unfolded state with the folding assembly at another view angle;

fig. 18 is a schematic view of the folding assembly of fig. 17 in a folded condition. In the present embodiment, the camping car 5 includes a frame body 51 and a wheel set 52. The frame body 51 includes a first frame 511, a second frame 512, and a folding assembly 513 connected between the first frame 511 and the second frame 512. The folding assembly 513 includes a folded state and an unfolded state. The first frame 511 and the second frame 512 have a smaller pitch in the folded state than in the unfolded state. The wheel set 52 includes a first wheel 521 and a second wheel 522. The first wheel 521 is connected to the first frame 511. The second wheel 522 is coupled to the second frame 512. Wherein in the folded state, an end of the frame body 51 facing away from the wheel set 52 protrudes or is flush with an end of the folding assembly 513 facing away from the wheel set 52. The end of the wheel set 52 facing away from the frame body 51 projects or is flush with the end of the folding assembly 513 adjacent to the wheel set 52.

In the present embodiment, the camping car 5 is used to load articles such as water, tent, clothes, food, etc., and is applicable to outdoor camping, and the camping car 5 can be folded to be easily accommodated.

In this embodiment, the folding assembly 513 includes a folded state and an unfolded state, and the distance between the first frame 511 and the second frame 512 in the folded state is smaller than the distance between the first frame 511 and the second frame 512 in the unfolded state, so that the occupied space of the camping car 5 when the first frame 511 is directed to the second frame 512 is greatly reduced after folding. Moreover, before and after the folding assembly 513 is folded, an end of the frame main body 51 facing away from the wheel set 52 protrudes or is flush with an end of the folding assembly 513 facing away from the wheel set 52, an end of the wheel set 52 facing away from the frame main body 51 protrudes or is flush with an end of the folding assembly 513 facing towards the wheel set 52, that is, the folding assembly 513 is not higher than the first frame 511 and the second frame 512 all the time, and the folding assembly 513 is not lower than the wheel set 52 all the time, so that the space occupied by the camping car 5 in the height direction of the camping car 5 is not increased before and after the folding, and the storage effect of the camping car 5 is further improved.

Specifically, when the folding assembly 513 is converted from the unfolded state to the folded state, the first wheel 521 moves together with the first frame 511 relative to the second wheel 522 and the second frame 512, and the space occupied by the first wheel 521, the first frame 511, the second wheel 522 and the second frame 512 in the direction in which the wheel set 52 points to the frame main body 51 is always kept constant, the folding frame is contracted during the relative movement of the first frame 511 and the second frame 512 to reduce the size of the folding frame in the direction in which the first frame 511 points to the second frame 512, and the folding frame is always not beyond the ends of the first frame 511 and the second frame 512 facing away from the wheel set 52 during the contraction, nor is also not lower than the wheel set 52, so that the occupied space of the camping vehicle 5 is not increased during the folding contraction. Similarly, the folding assembly 513 is configured to transition from the folded state to the unfolded state to a motion opposite the folding process.

Alternatively, the folding assembly 513 may be configured to transition between the folded state and the unfolded state by one or more of rotation, sliding, and elastic connection.

In summary, the camping car 5 provided by the present application sets the folding assembly 513 between the first frame 511 and the second frame 512, and the folding assembly 513 is in a folded state, where an end of the frame main body 51 facing away from the wheel set 52 protrudes or is flush with an end of the folding assembly 513 facing away from the wheel set 52. The end of the wheel set 52 away from the frame assembly protrudes out of or is flush with the end of the folding assembly 513 close to the wheel set 52, so that the space occupied by the camping car 5 in the direction of the wheel set 52 pointing to the frame assembly after folding is kept unchanged, and the camping car 5 can be stored conveniently. Therefore, the camping car 5 provided by the application occupies a small space after being folded and is easy to store.

Referring to fig. 17-20, fig. 19 is a partially enlarged schematic view of fig. 17 at I; fig. 20 is a partially enlarged schematic view of fig. 18 at II. In the present embodiment, the folding assembly 513 includes two rotating rods 5131 and two link mechanisms 5132. One end of one of the two rotation rods 5131 is rotatably connected to the first frame 511, one end of the other one is rotatably connected to the second frame 512, and the other ends of the two rotation rods 5131 are rotatably connected. One end of one of the two link mechanisms 5132 is rotatably connected to the first frame 511, one end of the other is rotatably connected to the second frame 512, and the other ends of the two link mechanisms 5132 are rotatably connected. The link mechanism 5132 has a first limit end 5134 and a second limit end 5135 disposed at intervals. The second spacing end 5135 is closer to the wheel set 52 than the first spacing end 5134. The rotation lever 5131 has an engagement portion 5133. The engaging portion 5133 is slidably connected to the link mechanism 5132 and is slidable between the first limit end 5134 and the second limit end 5135. When the folding assembly 513 is in the folded state, the mating portion 5133 is located at the second limiting end 5135. When the folding assembly 513 is in the unfolded state, the engaging portion 5133 is located at the first limiting end 5134.

In this embodiment, the number of the folding assemblies 513 is one or more, and when the number of the folding assemblies 513 is one, one end of the folding assembly 513 is rotatably connected to the middle region of the first frame 511, and the other end is rotatably connected to the middle region of the second frame 512. When the number of the folding assemblies 513 is two, one ends of the two folding assemblies 513 are respectively rotatably connected to two opposite sides of the first frame 511, and the other ends are respectively rotatably connected to two opposite sides of the second frame 512. In the present embodiment, the number of the folding assemblies 513 is schematically illustrated as two, and one of the folding assemblies 513 is described.

In the present embodiment, the rotation lever 5131 is rotatably connected to the first frame 511/second frame 512 and slidably connected to the link mechanism 5132 such that the rotation lever 5131 rotates with respect to the first frame 511/second frame 512 and slides with respect to the link mechanism 5132 during the transition of the folding assembly 513 from the unfolded state to the folded state. The link 5132 is rotatably coupled to the first frame 511/second frame 512 such that the link 5132 rotates with respect to the first frame 511/second frame 512 and slides with respect to the rotation lever 5131 during the transition of the folding assembly 513 from the unfolded state to the folded state.

Since the link mechanism 5132 has a first limit end 5134 and a second limit end 5135 disposed at intervals, the rotation rod 5131 has a mating portion 5133 slidably mated with the link mechanism 5132, so that the mating portion 5133 can slide between the first limit end 5134 and the second limit end 5135, thereby restricting the movement range of the rotation rod 5131 to prevent the rotation rod 5131 from exceeding the ranges of the wheel set 52, the first frame 511 and the second frame 512.

Specifically, the position where the rotation lever 5131 is connected to the first frame 511/second frame 512 is higher than the position where the link mechanism 5132 is connected to the first frame 511/second frame 512, and the position where the two rotation levers 5131 are rotatably connected to each other is lower than the position where the two link mechanisms 5132 are rotatably connected to each other, so that the rotation levers 5131 are in a cross shape with the link mechanism 5132. The second spacing end 5135 is closer to the wheel set 52 than the first spacing end 5134. When the folding assembly 513 is in the folded state, the engaging portion 5133 is located at the second limiting end 5135, and the rotating rod 5131 and the link mechanism 5132 have a first opening angle in a direction toward the wheel set 52. When the folding assembly 513 is in the unfolded state, the engaging portion 5133 is located at the first limiting end 5134, and the rotating rod 5131 and the link mechanism 5132 have a second opening angle in a direction toward the wheel set 52, and the second opening angle is larger than the first opening angle. When the folding assembly 513 is converted from the unfolded state to the folded state, the engaging portion 5133 is moved from the first limit end 5134 to the second limit end 5135, so that the rotation rod 5131 is rotated toward the wheel set 52, the link mechanism 5132 is rotated toward a direction away from the wheel set 52, and the second opening angle becomes the first opening angle. In this process, the rotation lever 5131 is not lower than the wheel set 52, and the link mechanism 5132 is not higher than the first frame 511 and the second frame 512. In the present embodiment, the high and low means a distance from the wheel set 52 in a direction in which the wheel set 52 is directed toward the frame body 51. In addition, since the relative sliding of the rotating rod 5131 and the link mechanism 5132 is limited to the sliding of the engaging portion 5133 between the first limit end 5134 and the second limit end 5135, the folding and unfolding stability of the folding assembly 513 is improved.

Further, the link mechanism 5132 includes a first sub-rod 5136 and a second sub-rod 5137. One end of the first sub-rod 5136 is rotatably coupled to the first frame 511 or the second frame 512. One end of the second sub-rod 5137 is rotatably coupled to the other end of the first sub-rod 5136. The first sub-rods 5136 of the two link mechanisms 5132 are rotatably connected to the first frame 511 and the second frame 512, respectively, and the other ends of the second sub-rods 5137 of the two link mechanisms 5132 are rotatably connected to each other. The folding structure further includes a locking member 5138. The locking member 5138 is provided at a junction of the two second sub-rods 5137, and the locking member 5138 is used to lock the two second sub-rods 5137 in the deployed state.

In this embodiment, the link mechanism 5132 includes the first sub-rod 5136 and the second sub-rod 5137, when the folding assembly 513 is converted from the unfolded state to the folded state, the first sub-rod 5136 rotates in a direction away from the wheel set 52 compared to the first frame 511/the second frame 512, and the second sub-rod 5137 rotates in a direction toward the wheel set 52 compared to the first sub-rod 5136, so that the link mechanism 5132 does not occupy too much space of the wheel set 52 directed toward the frame main body 51 during folding, and the folding assembly 513 is not higher than the first frame 511 and the second frame 512.

In the present embodiment, the locking member 5138 can lock the two second sub-rods 5137 in the unfolded state to improve the stability of the folding assembly 513 in the unfolded state. Further, the locking member 5138 can unlock the two second sub-levers 5137 after being pressed, so that the folding assembly 513 can be folded, i.e., the locking member 5138 can unlock the two second sub-levers 5137 by one key.

Referring to fig. 16, 17, 21 and 22, fig. 21 is a schematic structural view of a camping car according to another embodiment of the present disclosure; fig. 22 is a schematic view of the carriage of fig. 21 in an embodiment. In this embodiment, the camping car 5 further comprises a control assembly 53, a cabin 54, an auxiliary circuit assembly 55, and an electrical connection 56. The control component 53 is disposed on a side of the first frame 511 facing away from the second frame 512. The control component 53 includes a driver 531 and a control system 532. The driving member 531 is connected to the first frame 511, and is configured to drive the frame body 51 to move under the driving of an external force. The control system 532 is electrically connected to the first wheel 521, and is configured to control rotation of the first wheel 521 according to the magnitude and direction of the external force. The cabin 54 is detachably attached to the frame body 51. A shroud 541 is provided on a side of the carriage 54 adjacent to the wheel set 52. The auxiliary circuit assembly 55 is disposed on the second frame 512. The electrical connection 56 is used to electrically connect the control system 532 and the auxiliary circuit assembly 55. The electrical connector 56 includes a first electrical connection 561, a second electrical connection 562, and a third electrical connection 563 that are detachably connected in sequence. One end of the first electrical connection 561 is electrically connected to the control system 532. The second electrical connection portion 562 is partially received in the sleeve 541, and one end of the sleeve 541, which is close to the first frame 511, exposed by the second electrical connection portion 562 is electrically connected to the other end of the first electrical connection portion 561. The second electrical connection portion 562 is exposed at the other end of the tube housing 541 near the second frame 512 and is electrically connected to one end of the third electrical connection portion 563, and the other end of the third electrical connection portion 563 is electrically connected to the auxiliary circuit assembly 55.

In this embodiment, the control system 532 is disposed on a side of the first frame 511 away from the second frame 512, and the first wheel 521 is connected to the first frame 511, so that the folding assembly 513 does not pull the control system 532 and the connection harness of the control system 532 and the first wheel 521 during folding and unfolding, thereby avoiding the damage to the control system 532 and the connection harness of the control system 532 and the first wheel 521 during multiple folding and unfolding of the camper 5.

When the camping car 5 further comprises an auxiliary circuit assembly 55, the auxiliary circuit assembly 55 is disposed on the second frame 512, and the control system 532 and the auxiliary circuit assembly 55 are electrically connected through the electrical connector 56, so as to control the auxiliary circuit assembly 55 by implementing the control system 532.

Optionally, the electrical connector 56 is a wire harness.

Optionally, the auxiliary circuit assembly 55 includes an illumination lamp, an atmosphere lamp, a charging interface, and the like.

In this embodiment, the camping car 5 further includes a carriage 54, where the carriage 54 and the frame body 51 are used together to carry articles, and the carriage 54 is connected with the frame body 51 in a matching manner, so as to facilitate the disassembly, assembly and cleaning of the carriage 54.

The cabin 54 is provided with a pipe sleeve 541 on a side close to the wheel set 52, and a second electric connection portion 562 of the electric connection members 56 extends from the first frame 511 to the second frame 512 via the pipe sleeve 541, so that the pipe sleeve 541 can protect the second electric connection portion 562 from the outside, to avoid the second electric connection portion 562 from being exposed to the outside, and to avoid the second electric connection portion 562 from being eroded by water when the camper 5 travels in a relatively wet area. Further, the first electrical connection portion 561, the second electrical connection portion 562, and the third electrical connection portion 563 are sequentially detachably connected, so that the bending force of the folding assembly 513 on the electrical connection member 56 during the folding process can be weakened, and the maintenance and replacement of the electrical connection member 56 are facilitated. Further, the first electrical connection portion 561, the second electrical connection portion 562, and the third electrical connection portion 563 are sequentially connected in a rotating manner, so that the bending force of the folding assembly 513 on the electrical connection member 56 during the folding process is further reduced.

Optionally, the first electrical connection 561, the second electrical connection 562, and the third electrical connection 563 are all wire harnesses.

Optionally, the outer surface of the electrical connector 56 is covered with a fiber cover to further attenuate bending forces to which the electrical connector 56 is subjected during folding of the folding assembly 513.

Referring to fig. 22 and 23, fig. 23 is a schematic diagram illustrating the cooperation between the second electrical connection portion and the socket in fig. 22 in an embodiment. In this embodiment, the sleeve 541 includes a main body and elastic portions 5412 provided at opposite ends of the pipe main body 5411. The elastic portion 5412 is for elastically abutting against the outer peripheral side of the second electrical connection portion 562.

In the present embodiment, the elastic portion 5412 elastically contacts the outer peripheral side of the second electrical connection portion 562, and thus, it is possible to prevent entry of foreign substances such as water and dust through the opening of the pipe sleeve 541, thereby preventing corrosion contamination of the second electrical connection portion 562. For example, in the traveling process of the camping car 5, if the ground environment is dry, the elastic portion 5412 elastically abuts against the second electrical connection portion 562, so as to prevent dust from entering the pipe sleeve 541, thereby preventing the second electrical connection portion 562 and the pipe sleeve 541 from being polluted by the dust. If the ground environment is wet, after the elastic portion 5412 elastically abuts against the second point connection portion, water vapor can be prevented from entering the pipe sleeve 541, so that the second electrical connection portion 562 is prevented from being corroded by the water vapor.

Further, referring to fig. 16, 21, 22 and 24, fig. 24 is a schematic view of the structure of the water drain in fig. 23. In this embodiment, the inner wall of the sleeve 541 has a first slope structure 5413 and a second slope structure 5414 near the side of the wheel set 52. One end of the first slope structure 5413 is connected to one of the elastic parts 5412. One end of the second slope structure 5414 is connected to the other elastic portion 5412. The other end of the first ramp structure 5413 is connected to the other end of the second ramp structure 5414. The sleeve 541 has a drain opening 5415, and the drain opening 5415 is disposed at a connection portion between the first slope structure 5413 and the second slope structure 5414. The drain opening 5415 is lower than the elastic portion 5412 in a direction in which the wheel group 52 is directed toward the frame body 51.

In this embodiment, the pipe casing 541 is provided with a drain 5415 for draining water entering the pipe casing 541 so as to avoid water accumulating in the pipe casing 541 from corroding the second electrical connection 562. Specifically, a first slope structure 5413 and a second slope structure 5414 are provided on a side of the inner wall of the pipe casing 541 near the wheel set 52, the drain opening 5415 is provided at a connection portion between the first slope structure 5413 and the second slope structure 5414, when the camping car 5 is in the unfolded state of the folding assembly 513, the camping car 5 is in a normal running state, and the drain opening 5415 is located at a lowest position of the first slope structure 5413 and the second slope structure 5414, so that when water enters the pipe casing 541, the water slides to the drain opening 5415 along the first slope structure 5413 and the second slope structure 5414 under the action of gravity, and is discharged from the drain opening 5415.

Further, referring to fig. 16, 21, 22 and 25, fig. 25 is a schematic view of the structure of the one-way valve provided at the drain in fig. 24. In this embodiment, the sleeve 541 further includes a one-way valve 5416. The one-way valve 5416 is provided at the drain opening 5415 to allow water in the tube housing 541 to flow out through the drain opening 5415 and to block water outside the tube housing 541 from flowing in through the drain opening 5415. The drain opening 5415 and the check valve 5416 are disposed so as to avoid the center of the tube housing 541 in a direction in which the first frame 511 is directed toward the second frame 512.

In the present embodiment, by providing the one-way valve 5416 at the water outlet 5415, it is possible to prevent water from entering the pipe sleeve 541 from the water outlet 5415 during the traveling of the camping car 5, and further improve the waterproof effect of the pipe sleeve 541 on the second electrical connection portion 562.

Alternatively, the one-way valve 5416 may be a tesla one-way valve, a one-way water permeable membrane, or the like, so long as it is capable of allowing water within the tube housing 541 to flow out through the water outlet 5415 and blocking water outside the tube housing 541 from flowing in through the water outlet 5415.

In addition, in the present embodiment, the drain opening 5415 and the check valve 5416 are disposed away from the center of the tube casing 541, so that damage to the check valve 5416 caused by the folding assembly 513 during multiple unfolding and folding processes can be avoided.

Referring to fig. 16, 21, 22, 24 and 26, fig. 26 is a schematic structural diagram of the second electrical connection portion in fig. 22 in an embodiment. In this embodiment, the electrical connector 56 further includes a pressure relief boot 564. The pressure reducing sleeve 564 is disposed around the second electrical connection portion 562, and the pressure reducing sleeve 564 is disposed at least in a middle region of the second electrical connection portion 562 in a direction in which the first frame 511 is directed toward the second frame 512.

In this embodiment, in the direction in which the first frame 511 points to the second frame 512, the middle area of the second electrical connection portion 562 is the area where the second electrical connection portion 562 is bent to the greatest extent when the folding assembly 513 is folded, and by providing the pressure reducing sleeve 564 in the middle area of the second electrical connection portion 562, protection can be provided for the second electrical connection portion 562, so as to reduce the degree of bending of the second electrical connection portion 562, and thus reduce the damage of the second electrical connection portion 562 after multiple folds and unfolds of the folding assembly 513. Wherein the pressure reducing sleeve 564 is a ring-shaped sleeve having elasticity.

Further, the pressure reducing sleeve 564 is provided corresponding to the drain opening 5415. The relief sleeve 564 has a through hole 565, the opening of the through hole 565 facing the drain opening 5415.

In the present embodiment, a through hole 565 is provided at a side of the pressure reducing sleeve 564 facing the wheel set 52, and the through hole 565 is provided in alignment with the drain opening 5415 so that water entering between the pressure reducing sleeve 564 and the second electrical connection 562 can flow from the through hole 565 to the drain opening 5415.

Further, a groove is provided at the bottom of the pressure relief sleeve 564 to prevent the pressure relief sleeve 564 from blocking water entering the tube housing 541 from flowing to the drain opening 5415.

Further, the groove is in a tesla check valve 5416 structure, and when the folding assembly 513 is unfolded, the pressure reducing sleeve 564 elastically abuts against the pipe sleeve 541, so that the tesla check valve 5416 is formed by the inner wall of the pipe sleeve 541 and the groove, and the drainage and waterproof capabilities of the pipe sleeve 541 are further improved.

Referring to fig. 16, 21, 27 and 28, fig. 27 is a schematic structural view of the second electrical connection portion in fig. 22 in an expanded state in another embodiment; fig. 28 is a schematic structural view of the second electrical connection portion in fig. 27 in a folded state. In the present embodiment, the second electrical connection portion 562 includes a first sub-portion 5621, a second sub-portion 5622, and a third sub-portion 5623 that are sequentially connected. The second sub-portion 5622 is rotatably connected to the first sub-portion 5621 and the second sub-portion 5622, respectively. When in the deployed state, an end of the first sub-portion 5621 facing away from the second sub-portion 5622 is remote from an end of the third sub-portion 5623 facing away from the second sub-portion 5622. When in the folded state, an end of the first sub-portion 5621 facing away from the second sub-portion 5622 is adjacent to an end of the third sub-portion 5623 facing away from the second sub-portion 5622.

In this embodiment, the second sub-portion 5622 is disposed corresponding to a region of the sleeve 541 that needs to be bent when the folding assembly 513 is folded, so that when the folding assembly 513 is folded, the first sub-portion 5621 and the third sub-portion 5623 rotate compared to the second sub-portion 5622, and bending forces on the first sub-portion 5621 and the third sub-portion 5623 are avoided, thereby reducing damage to the second electrical connection portion 562.

Optionally, the second sub-portion 5622 is dimensioned smaller to avoid bending forces to the second sub-portion 5622.

Optionally, the second sub-portion 5622 is provided with two first electrical matching portions, the first sub-portion 5621 is provided with a second electrical matching portion, the third sub-portion 5623 is provided with a third electrical matching portion, and when the folding assembly 513 is in the unfolded state, one of the first electrical matching portions is electrically connected to and matched with the second electrical matching portion, and the other one of the first electrical matching portions is electrically connected to and matched with the third electrical matching portion. When the folding assembly 513 is converted from the unfolded state to the folded state, the first sub-portion 5621 rotates in a direction away from the wheel set 52 as compared to the second sub-portion 5622, and the first electric fitting portion is electrically disconnected from the second electric fitting portion, and the third sub-portion 5623 rotates in a direction away from the wheel set 52 as compared to the second sub-portion 5622, and the first electric fitting portion is electrically disconnected from the third electric fitting portion.

In other embodiments, the sleeve 541 is provided with a tightening member for tightening the sleeve 541. The tightening member is used to tighten the sleeve 541 as a whole when the folding assembly 513 is in the unfolded state, so as to ensure that the second electrical connection 562 is tightly attached to the sleeve 541 without loosening. When the folding assembly 513 is in the unfolded state, the tightening member is used to release the tube housing 541 to bend the second electrical connection portion 562 into a deformation space, thereby reducing the bending force applied to the second electrical connection portion 562.

Optionally, the second frame 512 is rotatably connected to the folding assembly 513, and the second frame 512 can be rotated with respect to the folding assembly 513 about a side of the folding assembly 513 near the wheel set 52 to lay the second frame 512 flat, thereby increasing the accommodation space of the cabin 54.

Optionally, the camping car 5 further comprises a small table rotatably connected to a side of the second frame 512 facing away from the wheel set 52, the small table being expandable for placing objects.

Optionally, the second frame 512 is provided with a metal net for improving the bearing capacity of the second frame 512, and preventing the weight of the camping car 5 from impacting the small table board during the driving process, so as to protect the small table board.

Optionally, the camping car 5 further comprises an accessory, which may be, but is not limited to, a mounting platform, an elastic net bag, a rain cover, etc. The mounting platform may be disposed on the first frame 511/the second frame 512, and is used for mounting a cradle head, a motion camera, and the like. The elastic net bag can be used for protecting and expanding large articles, and can be matched with the carriage 54 when the second frame 512 is closed and laid down so as to prevent the articles in the carriage 54 from falling. The rain-proof cover can with carriage 54 matchedly is connected for resist the rainwater, prevents article in the carriage 54 is drenched, in addition, the rain-proof cover is provided with scribbles silver surface fabric, is used for slowing down the promotion of temperature in the carriage 54, avoids under the sunshine insolatedly article damage in the carriage 54.

Referring to fig. 16 and 29, fig. 29 is a schematic view of the carriage of fig. 21 in another embodiment. In the present embodiment, the cabin 54 is detachably connected to the frame body 51. A shroud 541 is provided on a side of the carriage 54 adjacent to the wheel set 52. The tube housing 541 includes a first tube housing 5417 and a second tube housing 5418 disposed at intervals, and the first tube housing 5417 and the second tube housing 5418 together house the second electrical connection portion 562. Because the first tube sleeve 5417 and the second tube sleeve 5418 are spaced apart, a gap exists between the first tube sleeve 5417 and the second tube sleeve 5418, which is beneficial to the penetration and assembly of the second electrical connection portion 562. In addition, the gap between the first sleeve 5417 and the second sleeve 5418 provides a deformation space for the second electrical connection 562 after the folding assembly 513 is folded, so that the degree of bending the second electrical connection 562 is reduced. Specifically, the gap is located in the central area of the tube housing 541, and the dimension of the gap in the direction of the first tube housing 5417 pointing to the second tube housing 5418 is 5cm to 10cm, so that the second electrical connection portion 562 is inserted and assembled into the tube housing 541, and the tube housing 541 can provide relatively stable support and better protection for the second electrical connection portion 562. For example, the size of the void in the direction of the first tube sleeve 5417 toward the second tube sleeve 5418 may be, but is not limited to, 5cm, or 6cm, or 7cm, or 8cm, or 9cm, or 10cm, or other values between 5cm and 10 cm. If the dimension of the gap in the direction of the first sleeve 5417 toward the second sleeve 5418 is smaller than 5cm, assembly of the second electrical connection portion 562 with the sleeve 541 is not facilitated. If the size of the gap in the direction of the first sleeve 5417 toward the second sleeve 5418 is greater than 10cm, the sleeve 541 has too little wrapping area around the second electrical connection portion 562, resulting in insufficient support of the second electrical connection portion 562 by the sleeve 541 and excessive exposed area of the second electrical connection portion 562, which is susceptible to damage.

Further, in the foregoing embodiment, the design of the elastic portion 5412 shown in fig. 23, the slope structure and the design of the drain opening 5415 shown in fig. 24, and the design of the check valve 5416 shown in fig. 25 can be adaptively adjusted and then applied to the first sleeve 5417 and the second sleeve 5418 in the present embodiment.

While embodiments of the present application have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the present application, and that variations, modifications, alternatives and alterations of the above embodiments may be made by those skilled in the art within the scope of the present application, which are also to be regarded as being within the scope of the protection of the present application.
