When the user is moving over a short distance, it cannot serve as a means of transportation for the user to ride, and its function is single. Summary of the invention

[0004] In order to allow users to use the camper as a means of transportation during outdoor activities and improve the versatility of the camper, the present application provides a foldable camper.

[0005] The foldable camping vehicle provided in this application adopts the following technical solution: A foldable walking camper, comprising a frame and a control handle, wherein the frame comprises a support column, a side folding frame and a bottom folding frame, wherein the support columns are located at the four corners of the frame, adjacent support columns are connected by side folding frames, and the bottom folding frame is simultaneously connected to four support columns, and the four support columns are divided into two front support columns and two rear support columns, wherein a front wheel frame is rotatably provided at the bottom of the front support column, an electric drive wheel is rotatably provided at the bottom of the front wheel frame, a rear wheel frame is fixedly provided at the bottom of the rear support column, and a rolling wheel is rotatably provided on the rear wheel frame; the control handle is simultaneously connected to the two The front support column is connected, and a steering assembly and a control button are arranged on the control handle. The steering assembly is used to drive the front wheel frame to rotate, and the control button is electrically connected to the electric drive wheel. A detachable seat is installed on the top of the four support columns, and the seat can fix the distance between the support columns. The foldable camper has a folding state, a riding state, and a trailer state. In the folding state, all the side folding frames are completely folded; in the trailer state, all the side folding frames are completely unfolded; in the riding state, the seat is installed on all the support columns.

[0006] By adopting the above technical solution, when the user needs to carry items, the seat plate can be removed, and the side folding frame and the bottom folding frame are in a fully unfolded state, and the camper is adjusted to a trailer state. At this time, the side folding frame, the bottom folding frame, and the support column together form a storage frame, and the items can be placed in the storage frame, and the camper is pulled by pulling the control handle to move, so that the camper in this state can be used as an outdoor trailer; when the user needs a means of transportation, the side folding frame is appropriately adjusted and the seat plate is installed. The user sits on the seat plate and holds the control handle. The control button on the control handle is used to start the electric drive wheel to drive the camper to move forward automatically. At the same time, the steering assembly is used to control the steering of the electric drive wheel to control the forward direction of the camper, so that the camper can be directly ridden; when the camper is not used, the side folding frame and the bottom folding frame are folded, and the four support columns are close to each other. At this time, the camper is in a folded state, and the volume is reduced for easy carrying; in this way, the camper can be used as a short-distance means of transportation during outdoor activities, thereby improving the versatility of the camper.

[0007] Preferably, the control handle includes a handle body, a transverse rod, a connecting rod, and a connecting block. The connecting block is rotatably set on the side wall of the front support column. The handle body is located in the center of the two front support columns. The handle body is rotatably set in the middle of the transverse rod. One end of the connecting rod is rotatably connected to the end of the transverse rod, and the other end of the connecting rod is rotatably connected to the connecting block.

[0008] By adopting the above technical solution, when the two front support columns approach each other, the front support columns drive the connecting rod to deflect. At this time, the angle between the transverse rod and the connecting rod decreases, and the distance between the two connecting rods at one end away from each other decreases, thereby controlling the handle to be folded to provide space for the two front support columns to approach each other; when the handle body is pulled and the frame is pulled to move, the connecting block rotates relative to the front support column, and the handle body deflects and tilts to the side away from the frame, so as to facilitate the application of traction to the frame.

[0009] Preferably, in the riding state, the angle between the transverse rod and the connecting rod is 90°, and in the trailer state, the angle between the transverse rod and the connecting rod is 180°.

[0010] By adopting the above technical solution, in the riding state, the angle between the transverse rod and the connecting rod is 90°. At this time, the height of the top of the handle body is increased by the length of a connecting rod, which is convenient for the user to hold it with hand. At the same time, the distance between the two front support columns reduces the length of the two connecting rods, reduces the width of the camper, reduces the risk of the camper being hit during riding, and further makes the camper more convenient for users to ride; in the trailer state, the angle between the transverse rod and the connecting rod is 180°, the side folding frames between the two front support columns and between the two rear support columns are in the unfolded state, and the side folding frames between the front support columns and the rear support columns are in the unfolded state, which maximizes the accommodating space of the camper in the trailer state.

[0011] Preferably, the steering assembly includes a rotating disk, a wire rope, and a control disk. The rotating disk is coaxially fixed with the front wheel frame, the control disk is rotatably set on a transverse rod, and the control disk is fixedly connected to the handle body. Two wire ropes are provided, one of which is used to connect one of the rotating disks and the control disk, and the other wire rope is used to connect the other rotating disk and the control disk. The middle part of the wire rope is wound around the rotating disk, and both ends of the wire rope are fixedly set on the control disk. One end of the wire rope is located on one side of the axis of the control disk, and the other end of the wire rope is located on the other side of the axis of the control disk.

[0012] By adopting the above technical scheme, when the user deflects the handle body, the handle body drives the control disk to rotate, and the rotation of the control disk simultaneously drives the two steel wire ropes to move, thereby synchronously controlling the directions of the electric drive wheels on the two front wheel frames; since the middle part of the steel wire rope is wound around the rotating disk, and the two ends of the steel wire rope are fixed on the control disk, and one end is located on one side of the axis of the control disk, and the other end is located on the other side of the axis of the control disk, when the control disk rotates, one end of the steel wire rope located on one side of the axis of the control disk is tightened, and the other end of the steel wire rope located on the other side of the axis of the control disk is relaxed accordingly, and at the same time, under the action of the steel wire rope, the steel wire rope is wound into the rotating disk from one side of the rotating disk, and detached from the rotating disk from the other side of the rotating disk, thereby driving the rotating disk to rotate, thereby driving the front wheel frames to rotate, thereby realizing the control of the steering of the camper, and being able to effectively and flexibly control the steering of the camper according to the user's operating intentions, thereby improving the flexibility and safety of riding.

[0013] Preferably, the control panel is provided with two mounting surfaces along the axial direction, one end of the steel wire rope is fixedly connected to one of the mounting surfaces, and the other end of the steel wire rope is fixedly connected to the other mounting surface.

[0014] By adopting the above technical solution, the two mounting surfaces of the control panel along the axial direction make the wire ropes mutually staggered in the axial direction of the control panel, thereby maximizing the distance between the two ends of the wire rope and avoiding contact between the two ends of the wire rope as much as possible.

[0015] Preferably, the steering assembly also includes a sleeve, a first limiting block, and a second limiting block. The first limiting block is fixedly set on the transverse rod, and the second limiting block is fixedly set on the front support column. One end of the sleeve is fixedly connected to the first limiting block, and the other end of the sleeve is fixedly connected to the second limiting block. The sleeve is a deformable hose, and the sleeve passes through the transverse rod, the connecting rod, and the connecting block in sequence. The sleeve is sleeved between the end and the middle of the wire rope, and the sleeve is slidably matched with the wire rope.

[0016] By adopting the above technical scheme, on the one hand, the setting of the sleeve can protect the wire rope and prevent the wire rope from being worn and disturbed by the outside world during use; on the other hand, because the sleeve is a deformable hose with both ends fixed, at the same time, the length of the wire rope sliding into the sleeve is consistent with the length of the wire rope sliding out of the sleeve, and the length of the wire rope detaching from the control disk is consistent with the length of the wire rope wound into the rotating disk, so that the sleeve and the wire rope can be flexibly deformed with the movement of the transverse rod, the connecting rod and the connecting block, without affecting the normal operation of the steering assembly, further improving the stability and reliability of the entire steering assembly.

[0017] Preferably, a tensioning wheel is rotatably arranged inside the transverse rod, the tensioning wheel is located between the first limiting block and the control disk, and the wire rope is wound around the tensioning wheel.

[0018] By adopting the above technical solution, the tensioning wheel can tighten the wire rope, ensuring that the wire rope always maintains a certain tension in the process of transmitting force, and trying to avoid slack of the wire rope, thereby ensuring the accuracy and timeliness of the steering operation. At the same time, the tensioning wheel can reduce the friction between the wire rope and the transverse rod, extend the service life of the wire rope, and enable the steering assembly to maintain good performance during long-term use.

[0019] Preferably, the tensioning wheel is a bearing.

[0020] By adopting the above technical solution, since the bearing has good rotation performance and low friction coefficient, the wire rope can be passed around the tensioning wheel more smoothly, reducing the resistance and wear of the wire rope during the tensioning process, and further improving the working efficiency and service life of the steering assembly.

[0021] Preferably, the middle portion of the steel wire rope is fixedly connected to the rotating disk.

[0022] By adopting the above technical solution, the fixed connection between the middle part of the wire rope and the rotating disk is more stable, and relative sliding between the wire rope and the rotating disk can be avoided during the force transmission process, ensuring the accuracy and reliability of the steering action.

[0023] Preferably, an insertion rod is fixedly provided at the bottom of the seat plate, a slot is provided at the top of the support portion, and the insertion rod is inserted into the slot.

[0024] By adopting the above technical solution, the plug rod at the bottom of the seat plate is inserted into the slot at the top of the support part. The direct plug-in connection method is simple and fast, and can realize the rapid installation and disassembly of the seat plate and the support part. At the same time, the cooperation between the plug rod and the slot can provide better positioning and fixing effects. The seat plate can fix the distance between the supporting columns through the cooperation between the plug rod and the slot, thereby ensuring the stability and safety of the seat plate and the frame during use.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging a support column, a side folding frame, a bottom folding frame, a front support column, a rear support column, a front wheel frame, an electric drive wheel, a rear wheel frame, a rolling wheel, a control handle, a steering assembly, and a control button, the camper can be used as a short-distance means of transportation during outdoor activities, thereby improving the versatility of the camper; 2. By arranging the handle body, the transverse rod, the connecting rod, the connecting block, the rotating disk, the wire rope and the control disk, it is convenient for the user to control the steering of the camper. The operation is convenient and quick, and the steering of the camper can be flexibly controlled according to the user's operating intention, thereby improving the flexibility and safety of riding; 3. By setting the sleeve, the first limiting block, the second limiting block and the tensioning wheel, the sleeve and the wire rope can be flexibly deformed with the movement of the transverse rod, the connecting rod and the connecting block, without affecting the normal operation of the steering assembly, thereby further improving the stability and reliability of the entire steering assembly.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-10 This application is described in further detail.

[0038] The present application embodiment discloses a foldable camping vehicle. Figure 1 and Figure 2 , which includes a frame 1, which includes a support column 11, a side folding frame 12, and a bottom folding frame 13. The support columns 11 are located at the four corners of the frame 1, and adjacent support columns 11 are connected by the side folding frames 12. The bottom folding frame 13 is located at the bottom of the frame 1 and is connected to all the support columns 11. The four support columns 11 are divided into two front support columns 111 and two rear support columns 112. A front wheel frame 1111 is rotatably provided at the bottom of the front support column 111, and an electric drive wheel 1112 is rotatably provided at the bottom of the front wheel frame 1111. A rear wheel frame 1121 is fixedly provided at the bottom of the rear support column 112, and a rolling wheel 1122 is rotatably provided on the rear wheel frame 1121.

[0039] Reference Figures 1 to 4, a foldable control handle 2 is commonly provided on the two front support columns 111. The control handle 2 includes a handle body 21, a transverse rod 22, a connecting rod 23, and a connecting block 24. The connecting block 24 is rotatably provided on the side wall of the front support column 111, the handle body 21 is located in the center of the two front support columns 111, and the handle body 21 is rotatably provided in the middle of the transverse rod 22. One end of the connecting rod 23 is rotatably connected to the end of the transverse rod 22, and the other end of the connecting rod 23 is rotatably connected to the connecting block 24. A steering assembly 3 and a control button 211 are provided on the control handle 2. The control button 211 is located at the top of the handle body 21 and is electrically connected to the electric drive wheel 1112, and a battery is installed in the handle body 21. The steering assembly 3 is used to drive the front wheel frame 1111 to rotate. A detachable seat plate 4 is installed on the top of the four support columns 11, and four plug rods 41 are fixedly installed on the bottom of the seat plate 4. Each support column 11 has a slot 113, and the plug rod 41 can be inserted into the slot 113. The camper in this embodiment has three use states, namely riding state, trailer state, and folding state.

[0040] Reference Figure 1 In the riding state, the side folding frame 12 between the two front support columns 111 and the two rear support columns 112 is in a folded state, and the angle between the transverse rod 22 and the connecting rod 23 is 90°. The height of the top of the handle body 21 is raised by the length of a connecting rod 23, which is convenient for the user to hold. The distance between the two front support columns 111 is reduced by the length of the two connecting rods 23, and the camper becomes narrower. The seat plate 4 is installed on the support column 11 (that is, the insertion rod 41 is inserted into the slot 113), and the seat plate 4 fixes the distance between the support columns 11 by the cooperation between the insertion rod 41 and the slot 113. The user sits on the seat plate 4, holds the top of the handle body 21, and touches the control button 211 with his fingers and controls it at any time. By controlling the control button 211 on the handle 2, the electric drive wheel 1112 is started or stopped to drive the camper to move forward automatically. At the same time, the steering assembly 3 is used to control the steering of the electric drive wheel 1112 to control the forward direction of the camper, so as to directly ride the camper.

[0041] Reference Figure 2 In the trailer state, the seat plate 4 and the support column 11 are separated from each other (that is, the insertion rod 41 is separated from the slot 113). All side folding frames 12 are in the unfolded state. The angle between the transverse rod 22 and the connecting rod 23 in the trailer state is 180°. The side folding frames 12, the bottom folding frame 13, and the support column 11 together form a storage frame. The user can put the items in the storage frame and pull the handle body 21 to pull the camper to move. When the user pulls the handle body 21 and pulls the frame 1 to move, the connecting block 24 rotates relative to the front support column 111, and the handle body 21 deflects and tilts to the side away from the frame 1, which is convenient for towing the frame 1. The camper can also be powered forward by pressing a button.

[0042] Reference Figure 3 In the folded state, the seat plate 4 and the support column 11 are separated from each other (ie, the insertion rod 41 is separated from the slot 113). The side folding frame 12 and the bottom folding frame 13 are completely folded, and the four support columns 11 are close to each other. At this time, the camper is reduced in size for easy storage and carrying.

[0043] In order to facilitate the control of the rotation of the front wheel frame 1111, refer to Figure 5 and Figure 6 The steering assembly 3 includes a rotating disk 31, a wire rope 32, a control disk 33, a sleeve 37, a first limiting block 34, and a second limiting block 35. The rotating disk 31 is coaxially fixed with the front wheel frame 1111, the control disk 33 is rotatably arranged on the transverse rod 22, and the control disk 33 is fixedly connected to the handle body 21. Two wire ropes 32 are provided, one of which is used to connect one of the rotating disks 31 and the control disk 33, and the other wire rope 32 is used to connect the other rotating disk 31 and the control disk 33. The middle part of the wire rope 32 is wound around the rotating disk 31 and is fixedly connected to the rotating disk 31. One end of the wire rope 32 is located on one side of the axis of the control disk 33, and the other end is located on the other side of the axis of the control disk 33.

[0044] Reference Figure 6 The control panel 33 is provided with two mounting surfaces 331 along the axial direction. For any mounting surface 331, two ends of two steel wires 32 are simultaneously mounted and connected to the mounting surface 331. For any steel wire 32, one end of the steel wire 32 is fixedly connected to one mounting surface 331, and the other end is fixedly connected to the other mounting surface 331.

[0045] Reference Figure 5 , the first limiting block 34 is fixedly arranged on the transverse rod 22, and the second limiting block 35 is fixedly arranged on the front support column 111. One end of the sleeve 37 is fixedly connected to the first limiting block 34, and the other end is fixedly connected to the second limiting block 35. The sleeve 37 is a deformable hose, and the sleeve 37 passes through the inside of the transverse rod 22, the connecting rod 23, and the connecting block 24 in sequence. The sleeve 37 is sleeved between the end and the middle of the wire rope 32, and is slidably matched with the wire rope 32. A tensioning wheel 36 is rotatably arranged in the transverse rod 22, and the tensioning wheel 36 is a bearing. The tensioning wheel 36 is located between the first limiting block 34 and the control disk 33. The wire rope 32 enters the corresponding mounting surface 331 after passing through the tensioning wheel 36.

[0046] Reference Figure 5 and Figure 6When the front wheel frame 1111 needs to be controlled to rotate, the user tilts the handle body 21 to one side, and the handle body 21 drives the control disk 33 to rotate. The control disk 33 pulls one end of the wire rope 32, causing it to slide along the sleeve 37 away from the rotating disk 31, and the control disk 33 releases the other end of the wire rope 32, causing it to slide along the sleeve 37 toward the rotating disk 31. Under the action of the wire rope 32, the wire rope 32 is wound into the rotating disk 31 from one side of the rotating disk 31, and is separated from the rotating disk 31 from the other side of the rotating disk 31, thereby driving the rotating disk 31 to rotate, thereby driving the front wheel frame 1111 to rotate, and realizing the control of the camper's steering. Moreover, the sleeve 37 and the wire rope 32 can be flexibly deformed with the activities of the transverse rod 22, the connecting rod 23 and the connecting block 24, without affecting the normal operation of the steering assembly 3.

[0047] Reference Figure 2 , Figure 7 and Figure 8 In addition, in the present application, the bottom folding frame 13 specifically includes a first bottom frame block 131, a second bottom frame block 132, and a bottom frame rod 133. One second bottom frame block 132 is fixedly arranged at the bottom of each supporting column 11, and one bottom frame rod 133 is corresponding to each second bottom frame block 132. A universal ball 1331 is arranged at each end of the bottom frame rod 133, one end of the bottom frame rod 133 is connected to the corresponding second bottom frame block 132 through the universal ball 1331, and the other ends of all bottom frame rods 133 are connected to the same first bottom frame block 131 through the universal ball 1331. When the present application is in the trailer state, the bottom frame rod 133, the second bottom frame block 132, and the first bottom frame block 131 are flush in the height direction.

[0048] Reference Figure 3 , Figure 7 and Figure 8The first chassis block 131 has four corners with first long-direction slide grooves 1311 along the length direction of the frame 1 (i.e., the horizontal line direction between the front support column 111 and the rear support column 112), and has a first wide-direction slide groove 1312 connected to the end of the first long-direction slide groove 1311 along the width direction of the frame 1 (i.e., the horizontal line direction between the two front support columns 111 or the two rear support columns 112). One end of the chassis rod 133 slides in the first long-direction slide groove 1311 or the first wide-direction slide groove 1312. The second chassis block 132 has a second long-direction slide groove 1321 along the length direction of the frame 1, and has a second wide-direction slide groove 1322 connected to the end of the second long-direction slide groove 1321 along the width direction of the frame 1. The other end of the chassis rod 133 slides in the second long-direction slide groove 1321 or the second wide-direction slide groove 1322. When the ends of the bottom frame rod 133 are located in the first longitudinal slide groove 1311 and the second longitudinal slide groove 1321, the support columns 11 can only move along the length direction, and when the ends of the bottom frame rod 133 are located in the first width slide groove 1312 and the second width slide groove 1322, the support columns 11 can only move along the width direction. In this way, the moving paths of the support columns 11 when they are close to or away from each other are constrained and optimized.

[0049] Reference Figure 3 and Fig. 9 The side folding frame 12 is specifically divided into two types, one is used between the front support column 111 and the rear support column 112, and the other is used between the two front support columns 111 or between the two rear support columns 112. The side folding frame 12 used between the front support column 111 and the rear support column 112 includes a first folding rod 121, a second folding rod 122, and a third folding rod 123. Two of the first folding rod 121, the second folding rod 122, and the third folding rod 123 are provided. One end of the two first folding rods 121 is hinged to each other, the other end of the first folding rod 121 is hinged to the support column 11, the ends of the two second folding rods 122 are hinged to each other, the middle of the second folding rod 122 is hinged to the middle of the first folding rod 121, one end of the third folding rod 123 is hinged to the second folding rod 122, and the other end of the third folding rod 123 is hinged to the support column 11.

[0050] Reference Figure 3 and Fig.10 The side folding frame 12 used between the two front support columns 111 or between the two rear support columns 112 includes a fourth folding rod 124 and a fifth folding rod 125. The fourth folding rod 124 and the fifth folding rod 125 are each provided with two. The end of the fourth folding rod 124 is hinged to the support column 11, the middle parts of the two fourth folding rods 124 are hinged to each other, one end of the fifth folding rod 125 is hinged to the fourth folding rod 124, and the other end of the fifth folding rod 125 is hinged to the support column 11.

[0051] The implementation principle of a foldable walking camper in the embodiment of the present application is as follows: under different usage requirements, the camper can be converted between a riding state, a trailer state and a folding state by changing the state. In the riding state, the distance between each supporting body is adjusted and the seat plate 4 is inserted. The user can sit on the seat plate 4 and control the electric drive wheel 1112 by controlling the control button 211 on the handle 2 to drive the camper forward. And by tilting the handle body 21 to one side, the handle body 21 drives the control disk 33 to rotate. The control disk 33 pulls one end of the wire rope 32 so that it slides along the sleeve 37 away from the rotating disk 31, and the control disk 33 releases the other end of the wire rope 32 so that it slides along the sleeve 37 toward the rotating disk 31. Under the action of the wire rope 32, the wire rope 32 is wound into the rotating disk 31 from one side of the rotating disk 31, and is separated from the rotating disk 31 from the other side of the rotating disk 31, thereby driving the rotating disk 31 to rotate, thereby driving the front wheel frame 1111 to rotate, and realizing the control of the camper's steering. In this way, during outdoor activities, the user can use the camper in the riding state as a means of transportation. In the trailer state, the seat plate 4 is removed, and the side folding frame 12 is unfolded to form a storage frame. The handle body 21 can be flexibly tilted during the towing process, and can also provide assistance with the help of the button. In this way, during outdoor activities, the user can use the camper in the trailer state as a means of transportation. In the folded state, the seat plate 4 is removed, the side folding frame 12 and the bottom folding frame 13 are completely folded, and the support column 11 is close to each other, which greatly reduces the volume of the camper for easy storage and carrying.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
