[0039] like Figure 1-Figure 6 , Fig.10As shown, the utility model provides a foldable seat plate of a foldable camper, characterized in that it includes: a plurality of X-shaped brackets 101 and a plurality of connecting seats 102; the plurality of X-shaped brackets 101 surround a frame 10 having a receiving cavity in the middle, the plurality of connecting seats 102 are used to connect two adjacent X-shaped brackets 101 together, the X-shaped brackets 101 can rotate relative to the connecting seats 102, the bottom ends of the frame 10 are respectively rotatably connected with wheels 103, a steering structure 11 is connected between the two wheels 103 at one end, and the steering structure 11 is used to To drive the rotation of the two wheels 103, the frame 10 is provided with a steering structure 11 at one end thereof and is also connected with a pull rod 12, the pull rod 12 can rotate horizontally in situ, the bottom end of the pull rod 12 is rotationally connected with the steering structure 11, and the rotation of the pull rod 12 drives the steering structure 11 to move, the frame 10 is provided with a seat device 14 rotationally connected to the top end of the pull rod 12, and the seat device includes: a plurality of support rods and a seat plate, one end of a plurality of the support rods is respectively rotationally connected with the seat plate, and the other end of a plurality of the support rods is respectively detachably connected with the frame;

[0040] Specifically, the vehicle frame 10 is composed of a plurality of X-shaped brackets 101 and a plurality of connecting seats 102. The X-shaped brackets 101 are surrounded from front to back, left to right, and in this embodiment, a rectangle is used for explanation. The connecting seats 102 are used to connect the X-shaped brackets 101 on adjacent sides, such as the front side and the left side, the front side and the right side, the left side and the rear side; the X-shaped brackets 101 on adjacent sides are rotatably connected through the connecting seats 102, respectively, and the X-shaped brackets 101 can rotate relative to the connecting seats 102. The connecting seats 102 are distributed at the top and bottom of the adjacent X-shaped brackets 101 on both sides, and telescopic tubes (not shown in the figure) are respectively provided between each upper and lower corresponding connecting seats 102, and one telescopic tube connects one connecting seat 1 02, so that the telescopic tube can be extended and retracted, and at the same time each X-shaped bracket 101 can rotate relative to its own intersection, thereby rotating relative to the connecting seat 102 to achieve folding. In this embodiment, in order to increase the accommodating area of ​​the frame 10, there are two X-shaped brackets 101 on the left and right sides respectively, and they are rotatably connected to each other, so as to increase the length of the frame 10 without affecting the folding. It should be pointed out that an X-shaped support frame (not shown in the figure) is also provided at the bottom of the frame 10. The support frame also adopts a folding design. The four end points of the support frame are respectively rotatably connected to the four connecting seats 102 located at the bottom. When the support frame is folded, the connecting seats 102 can be pulled together to achieve the frame The frame 10 is folded, and wheels 103 are rotatably connected under the four connecting seats 102 at the bottom. The two wheels 103 at one end are connected to a steering structure 11. The steering structure 11 is used to promote the rotation of the two wheels 103. A pull rod 12 is also connected to the end of the frame 10 provided with the steering structure 11, and the pull rod 12 can rotate horizontally relative to the frame 10. The bottom of the pull rod 12 is rotatably connected to the steering structure 11. When the pull rod 12 rotates horizontally on the frame 10, it will drive the steering structure 11 to move, and the steering structure 11 will drive the wheels 103 to rotate, so as to adjust the direction of the wheels 103 by rotating the pull rod 12. At the same time, a pull rod 12 is also provided above the end of the frame 10 provided with the steering structure 11. A seat device 14 is connected, one end of which is connected to the connection seat 102 at the top, and the other end is connected to the corresponding X-shaped bracket 101, so that the seat device 14 is suspended on one end of the frame 10. When the frame 10 needs to be folded, the end of the seat device 14 connected to the X-shaped bracket 101 can be separated to allow the frame 10 to be folded; wherein, the wheel 103 at at least one end is a driving wheel with a hub motor, which can generate power output after being powered on to drive the frame 10 to move. A controller (not shown in the figure) for controlling the operation of the driving wheel and a power supply (not shown in the figure) for providing energy to the driving wheel are also provided on the frame 10, so that the riding of the camper can be realized through electrification;

[0041] The seat device 14 comprises: a plurality of support rods 141 and a seat plate 142, one end of each of the support rods 141 is rotatably connected to the bottom of the seat plate 142, and the plurality of support rods 141 are arranged in an X shape, and one end of each of the support rods 141 away from the seat plate 142 is detachably connected to the corresponding connecting seat 102 and the X-shaped bracket 101 on the side. When the seat device 14 is needed, the seat device 14 is unfolded and fixed to the frame 10 through fasteners such as screws, so that the seat device 14 is suspended on one end of the frame 10. The user can sit on the seat device 14, and the pull rod 12 controls the direction. When the frame 10 is folded, the pull rod 12 controls the direction. When folding, the seat device 14 can be removed and covered on the frame 10, and can be fixed by fasteners; it should be noted that the seat device 14 can also be rotatably connected to the frame 10, that is, the two support rods 141 connected to the connecting seat 102 are respectively rotatably connected to the connecting seat 102, and one end of the two support rods 141 connected to the seat plate 142 can be set to rotate in one direction or in two directions. The unidirectional rotation can be used to adapt to the folding type of vehicle body, and the two-way rotation can be used to adapt to the gathering type of vehicle body, wherein the two-way rotation means that the support rod 141 can rotate both horizontally and vertically relative to the seat plate 142.

[0042] It should be pointed out that, for the convenience of control, the pull rod 12 is also electrically connected to the controller, and the pull rod 12 is provided with a number of control buttons (not shown in the figure) for control effects, such as speed, start and stop, switching between electric power-assist mode and manual mode, etc.; among them, since the camping car has the function of carrying people, the driving wheels are all equipped with mechanical brakes, such as drum brakes, disc brakes, etc. The braking method can refer to the existing vehicle structure, so it will not be described here one by one.

[0043] Furthermore, the frame 10 is gathered from front to back and left to right to the middle;

[0044] Furthermore, the steering structure 11 includes a plurality of connecting rods 111, and the plurality of connecting rods 111 are connected together end to end, and the head end and the tail end of the connected connecting rods 111 are respectively connected to the corresponding wheels 103 for rotation;

[0045] Specifically, the vehicle frame 10 is a convergent type frame 10, and the frame 10 is folded from the front, back, left and right directions to the middle. In the present embodiment, since the vehicle frame 10 is a convergent type, in order to prevent the steering structure 11 from limiting the folding of the frame 10, the steering structure 11 includes a plurality of connecting rods 111 rotatably connected end to end, and the plurality of connecting rods 111 can be rotated and folded with each other to adapt to the folding of the frame 10. The head and tail ends of the plurality of connecting rods 111 connected as one are respectively rotatably connected to the corresponding wheels 103 at the same end, and the movement of the steering structure 11 will drive the wheels 103 to rotate.

[0046] Furthermore, the bottom sides of the pull rod 12 are rotatably connected to support rods 121 respectively, and one end of the support rod 121 away from the pull rod 12 is rotatably connected to the two sides of the frame 10;

[0047] Specifically, in order to adapt to the gathered type of frame 10, support rods 121 are rotatably connected to the two sides of the bottom of the pull rod 12, and the support rod 121 can rotate vertically relative to the pull rod 12. At the same time, the end of the support rod 121 away from the pull rod 12 is rotatably connected to the corresponding connecting seat 102, and the support rod 121 can also rotate vertically relative to the connecting seat 102. When the frame 10 is gathered, since the two support rods 121 are rotatable, they will be squeezed by the connecting seats 102 on both sides of the frame 10, so that they are rotated upward relative to the connecting seats 102 and lift the pull rod 12 up. The pull rod 12 is supported by the support rod 121 and is located outside the end of the frame 10, and the pull rod 12 can rotate horizontally relative to the support rod 121. A steering swing arm (not shown in the figure) is provided at the bottom of the pull rod 12, and the pull rod 12 is connected to the steering structure 11 through the steering swing arm.

[0048] Furthermore, the adjacent ends of the two struts 121 are respectively embedded with synchronous teeth 123, the two synchronous teeth 123 are meshed, the adjacent ends of the two struts 121 are connected together through a connecting sleeve 122, the bottom of the pull rod 12 is rotatably connected to the connecting sleeve 122, and the pull rod 12 can rotate horizontally relative to the connecting sleeve 122;

[0049] Specifically, the two struts 121 are connected together by a connecting sleeve 122, and the two struts 121 can rotate vertically relative to the connecting sleeve 122. The bottom of the pull rod 12 is located on the outside of the connecting sleeve 122 and is rotatably connected to the connecting sleeve 122 through a bearing. Since the two struts 121 are not directly connected, the rotation angles of the two struts 121 will be different during rotation, causing the connecting sleeve to tilt, thereby causing the pull rod 12 to tilt left and right. To avoid this situation, synchronous teeth 123 are respectively embedded on the adjacent ends of the two struts 121. The two synchronous teeth 123 are meshed with each other. The meshing of the gears limits the two struts 121 to rotate synchronously at the same angle, thereby ensuring that the pull rod 12 is always in a vertical state.

[0050] It should be noted that, since the two synchronous teeth 123 are in a meshing state, the two synchronous teeth 123 are located on the outside of the support rod 121, which causes the end of the synchronous tooth 123 to rotate when the support rod 121 rotates. At this time, it will hit the connecting kit 122, and will be unable to continue to rotate after being restricted by the connecting kit 122, so that the frame 10 cannot be completely folded under the restriction of the support rod 121. To avoid this situation, one or two slots corresponding to the synchronous teeth 123 need to be opened on the connecting kit 122, so that the synchronous teeth 123 can pass through the connecting kit 122 and are not restricted by the connecting kit 122.

[0051] Furthermore, in this embodiment, a folding structure 124 is provided at the bottom of the pull rod 12, and the folding structure 124 is used to enable the pull rod 12 to rotate vertically;

[0052] Specifically, in order to make it more convenient and labor-saving for the user to tow the bicycle, a folding structure 124 is provided at the bottom of the pull rod 12. The folding structure 124 is used to enable the pull rod 12 to rotate vertically, specifically, to rotate in the front-to-back direction, so that the pull rod 12 can be tilted forward at a certain angle according to the needs of the user when towing, making towing more convenient. When the pull rod 12 is tilted, it can also rotate horizontally, thereby facilitating the control of the direction of the frame 10.

[0053] Among them, the folding structure in this embodiment provides two embodiments, one of which is as follows Figure 1 As shown, the pull rod 12 itself is a telescopic structure, which can change its own length according to usage requirements. In this case, the folding structure 124 includes: a movable head (not shown in the figure), which is rotatably connected to the connecting kit 122, and the movable head can rotate horizontally relative to the connecting kit 122. The direction swing arm is fixedly connected to the bottom end of the movable head, and the tail end of the pull rod 12 is hinged to the top end of the movable head, so that the pull rod 12 can rotate vertically relative to the movable head, thereby realizing the tilting of the pull rod. At the same time, since the movable head can rotate horizontally relative to the connecting kit 122, the movable head can be driven by the pull rod 12 to rotate horizontally, thereby realizing the control of the direction of the wheel 103.

[0054] Second, if Figure 7-Figure 9 As shown, the folding structure 124 includes: a first folding member 1241 and a second folding member 1242, the second folding member 1242 is rotatably connected to the support rod 121, the second folding member 1242 can be horizontally rotated relative to the support rod 121, the first folding member 1241 is rotatably connected to the ends of the second folding member 1242, the first folding member 1241 can be vertically rotated relative to the support rod 121, the pull rod 12 is inserted into the first folding member 1241 and the second folding member 1242, and can slide relative to the first folding member 1241 and the second folding member 1242;

[0055] Specifically, when the pull rod 12 is integrally formed, the folding structure 124 includes: a first folding piece 1241 and a second folding piece 1242, the second folding piece 1242 is rotatably connected to the connecting kit 122, the second folding piece 1242 can be horizontally rotated relative to the connecting kit 122, the direction swing arm is fixedly connected to the bottom of the second folding piece 1242, the first folding piece 1241 is hinged to the top of the second folding piece 1242, the first folding piece 1241 can be vertically rotated relative to the second folding piece 1242, and the pull rod 12 is inserted into the first folding piece 1241 and the second folding piece 1242, and can be in the first folding piece 12 The first folding member 1241 and the second folding member 1242 slide between each other to adjust the height of the pull rod 12 to adapt to different usage requirements, wherein a protruding connecting ear 1243 is respectively provided on one end where the first folding member 1241 and the second folding member 1242 are connected, the connecting ears 1243 of the first folding member 1241 and the second folding member 1242 are staggered and connected together by a pin shaft, and when the first folding member 1241 and the second folding member 1242 are in an initial state, one side of the first folding member 1241 and the second folding member 1242 coincide with each other, so that the two are in a vertical state and can only rotate in one direction in this state. At the same time, in order to increase the rotation angle, the first folding member 1241 and the second folding member 1242 are connected to each other by a pin shaft. The first folding member 1241 and the second folding member 1242 are respectively provided with chamfers (not shown in the figure) on one side of the rotation direction. Through the setting of the chamfers, the end side walls of the first folding member 1241 and the second folding member 1242 have avoidance space, so that when rotating, a predetermined angle can be reached, and after reaching the predetermined angle, the end side walls of the first folding member 1241 and the second folding member 1242 abut against each other, so that the first folding member 1241 and the second folding member 1242 cannot continue to rotate; when controlling the direction, the first folding member 1241 needs to drive the second folding member 1242 to rotate in the horizontal direction, in order to avoid force concentration At the connection point of the connecting ear 1243, a concave-convex matching structure is provided on the side where the first folding part 1241 and the second folding part 1242 match each other in the initial state, and the concave-convex matching structure is non-circular, so that the force concentrated on the connecting ear 1243 when the first folding part 1241 and the second folding part 1242 rotate horizontally is reduced through the concave-convex structure 1244, thereby improving the service life of the folding structure 124; wherein, the pull rod 12 is a waist-shaped tube, and the length of the horizontal cross-section of the pull rod 12 coincides with the straight line between the frame 10 and the support rod 121, thereby ensuring that the pull rod 12 has sufficient strength and will not be deformed when being dragged.

[0056] Furthermore, the first folding member 1241 is also provided with a limiting device 1245 cooperating with the pull rod 12, and the limiting device 1245 is used to limit the sliding of the pull rod 12;

[0057] Specifically, since the pull rod 12 can slide on the first folding piece 1241 and the second folding piece 1242, in order to ensure the stability of the pull rod 12 when in use, a limiting device 1245 is provided on the first folding piece 1241. The limiting device 1245 is a bayonet pin, and a plurality of bayonet holes (not shown in the figure) adapted to the bayonet pin are opened on the pull rod 12. The fixing of the pull rod 12 is achieved through the cooperation of the bayonet pin and the bayonet hole. The fixing method of the limiting device 1245 is preferably fixed from the outside to the inside, so as to avoid affecting the sliding of the pull rod in the first folding piece 1241 and the second folding piece 1242. The structure is simple, the cost is low, and the assembly is convenient. When it is needed to ride, the pull rod 12 is first lifted upwards to make The bottom of the pull rod 12 is located in the second folding piece 1242, so that the pull rod 12 is at a sufficient height and is fixed by the limit device 1245, which makes it easy to ride. When towing is required, the pull rod 12 is lifted upward so that the bottom of the pull rod 12 is located in the first folding piece 1241 and is fixed by the limit device 1245. At this time, since the restriction of the pull rod 12 is lost between the first folding piece 1241 and the second folding piece 1242, the first folding piece 1241 can rotate relative to the second folding piece 1242, so that the pull rod 12 is in an inclined state. Moreover, since the pull rod 12 is located in the first folding piece 1241, the overall length of the pull rod 12 outside is increased, which effectively improves the convenience and effort saving of towing.

[0058] It should be pointed out that, in the present embodiment, there are three card holes, corresponding to the riding state, the towing state, and the folded state respectively; the folded state is used to lower the height of the pull rod 12 when the frame 10 is folded. At this time, the bottom of the pull rod 12 can pass through the outside of the second folding member 1242, thereby shortening the height of the pull rod 12 to adapt to the height of the frame 10 in the folded state.

[0059] Furthermore, the frame 10 is provided with a clamp device 13 at one end of the pull rod 12 for limiting the vertical rotation of the pull rod 12, and the clamp device 13 includes: a clamp sleeve 131 and a clamp bar 132; the clamp sleeve 131 is adapted to the pull rod 12 and is arc-shaped, one end of the clamp bar 132 is rotatably connected to one end of the clamp sleeve 131, and the top side of the other end of the clamp sleeve 131 is provided with a clamp groove 133 adapted to the clamp bar 132, and the clamp bar 132 is clamped in the clamp groove 133;

[0060] Specifically, in this embodiment, the frame 10 can carry passengers. In order to ensure that the pull rod 12 does not move around when it is in the carrying state, a clamp device 13 is also provided in the middle of one end of the frame 10 where the pull rod 12 is provided. The clamp device 13 includes a hoop 131 and a hoop strip 132. The hoop 131 is arc-shaped and the hoop 131 is adapted to the pull rod 12. When the pull rod 12 is located in the hoop 131, the pull rod 12 can also rotate horizontally in the hoop 131. The hoop strip 132 and the hoop 131 are connected. The hoop sleeve 131 is rotatably connected at one end, and the other end of the hoop sleeve 131 is also provided with a hoop groove 133, which is adapted to the hoop strip 132, and the hoop strip 132 can be inserted into the hoop groove 133. When the pull rod 12 is located in the hoop sleeve 131, the hoop strip 132 can be inserted into the hoop groove 133, so that the pull rod 12 is restricted from escaping from the hoop sleeve 131 by the hoop strip 132, and the hoop sleeve 131 is fixedly connected to the frame 10, so that it can ensure that the pull rod 12 is always in a vertical state and will not tilt forward, thereby improving the safety of use.

[0061] It should be pointed out that the clamp device 13 is suitable for the pull rod 12 adopting the first folding structure 124 , and the second folding structure 124 can cancel the setting of the clamp device 13 .

[0062] Furthermore, the hoop strip 132 is a magnetic metal part, and the hoop groove 133 is also provided with a magnetic part (not shown in the figure), and the magnetic part cooperates with the hoop strip 132 by magnetic attraction; specifically, in order to prevent the hoop strip 132 from detaching from the hoop groove 133 due to jumping during driving, the hoop strip 132 can be configured as a magnetic metal part, and a magnetic part, such as a magnet, is installed in the hoop groove 133, so that when the hoop strip 132 is inserted into the hoop groove 133, the magnetic attraction cooperation between the magnetic part and the hoop strip 132 further improves the clamping stability of the hoop strip 132.

[0063] Further, such as Fig.11 As shown, the present application also provides a second embodiment of the clamp device 13, wherein the position limiting member comprises: a clamp strip 132; the clamp strip 132 is arc-shaped, one end of the clamp strip 132 is rotatably connected to one end of the clamp sleeve 131, and the other end of the clamp sleeve 131 is provided with a clamp groove 133 adapted to the clamp strip 132 on the front side, and the top of the end of the clamp sleeve 131 provided with the clamp groove 133 is also provided with a spring bayonet 135;

[0064] Specifically, the hoop strip 132 is arc-shaped and matched with the outer curvature of the pull rod 12. The hoop strip 132 is rotatably connected to one end of the hoop sleeve 131. The other end of the hoop sleeve 131 is provided with a hoop groove 133. A spring pin 135 is provided at the top of the end of the hoop sleeve 131 where the hoop groove 133 is provided. When the end of the hoop strip 132 is located in the hoop groove 133, the spring pin 135 restricts the end of the hoop strip 132 from escaping from the hoop groove 133, and the pull rod 12 can rotate horizontally in the clamp device 13, so that the pull rod 12 can control the movement of the steering structure 11; in the second method, since the hoop strip 132 is arc-shaped, it can better fit the outer side of the pull rod 12, thereby reducing the gap between the hoop strip 132 and the pull rod 12 and reducing the shaking of the pull rod 12.

[0065] Furthermore, a limiting pin 134 is provided at one end of the hoop strip 132 away from the rotatable connection with the hoop sleeve 131, and the limiting pin 134 is used to limit the hoop strip 132 in the hoop groove 133;

[0066] Specifically, since the hoop 131 is made of plastic material, it has certain deformation characteristics. In order to prevent the hoop 131 from expanding due to the force generated by the pull rod 12 during use, a limit pin 134 is provided at the end of the hoop strip 132 away from the rotational connection with the hoop 131. The limit pin 134 abuts against the side wall of the hoop 131, and limits the expansion of the hoop 131 through the limit pin 134, thereby preventing the hoop strip 132 from detaching from the hoop 131.

[0067] The frame 10 has two embodiments. One is that the frame 10 is a gathering type as described above, and the other is a folding type, that is, the folding of the frame 10 is limited to folding toward the middle from front to back, while the left and right sides will not be folded; therefore, in this state, the corresponding positions have some changes. First, since the frame 10 does not need to be brought together left and right, the support rod 121 can also be directly set into an integral shape, and the structure of the synchronous tooth 123 can also be omitted. Second, the pad cloth 142 can be set as a hard structure, such as a wooden board, and other structures are the same as the first embodiment. Third, the X-shaped bracket 101 at the front end face and the rear end face of the frame 10 can be replaced with a rectangular bracket.

[0068] It should be pointed out that, whether the frame 10 is the first embodiment or the second embodiment, the horizontal rotation center of the tie rod 12 needs to be on the same straight line with the wheel 103 at the same end, so that when the tie rod 12 rotates horizontally, the steering arm can drive the steering structure 11 to move. Otherwise, due to the different movement trajectories of the steering arm and the steering structure 11, the wheel 103 and the tie rod 12 will rotate asynchronously, thereby affecting the steering effect; or a slide groove is provided on the steering arm so that the connection point between the steering structure 11 and the steering arm can change the relative position, which can also avoid the occurrence of movement conflict; it should be noted that when the frame 10 is a gathering type, the clamp device 13 needs to be rotatably set on the frame 10, so that the tie rod 12 can be in an upright state when the frame 10 is folded, so as to avoid movement conflict between the clamp device 13 and the tie rod 12; if the frame 10 is a folding type, since the frame does not need to be folded on the left and right sides, the clamp device 13 can be fixed on the frame.

[0069] In summary, the utility model provides a seat device 14 on the frame 10, so that the camping vehicle not only has the function of carrying goods, but also has the function of carrying people, which further improves the user experience of the camping vehicle, and can switch between electric, manual and passenger modes to better meet different usage needs. At the same time, in order to facilitate the control of direction when riding, a steering structure 11 is also provided between the wheels 103 to simultaneously control the steering of the two wheels 103, with precise pointing, which helps to improve the user experience and safety.

[0070] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
