Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-7 As shown, this utility model provides a rideable folding electric camping vehicle, 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 central cavity; the plurality of connecting seats 102 are used to connect two adjacent X-shaped brackets 101 together; the X-shaped brackets 101 are rotatable relative to the connecting seats 102; wheels 103 are rotatably connected to both ends of the bottom of the frame 10; and a connection is made between two wheels 103 at one end. A steering structure 11 is provided to synchronize the rotation of the two wheels 103. A tie rod 12 is connected to one end of the frame 10 where the steering structure 11 is located. The tie rod 12 can rotate horizontally in place. The bottom end of the tie rod 12 is rotatably connected to the steering structure 11. When the tie rod 12 rotates, it drives the steering structure 11 to move. A seat device 14 is rotatably connected to the top of one end of the frame 10 where the tie rod 12 is located. The other end of the seat device 14 is connected to the corresponding X-shaped bracket 101.

[0032] Specifically, the frame 10 consists of several X-shaped brackets 101 and several connecting seats 102. The X-shaped brackets 101 are arranged in a circular shape from front to back and left to right. In this embodiment, a rectangle is used as an example. The connecting seats 102 are used to connect adjacent X-shaped brackets 101 together, such as the front and left sides, the front and right sides, and the left and right sides and the rear sides. The adjacent X-shaped brackets 101 are rotatably connected by the connecting seats 102. 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 two X-shaped brackets 101, and each corresponding upper and lower connecting seat 102 is provided with a telescopic tube (not shown in the figure). One telescopic tube connects one Each X-shaped bracket 102 is a connecting seat 102, allowing the telescopic tube to extend and retract. Simultaneously, each X-shaped bracket 101 can rotate relative to its intersection, thereby rotating relative to the connecting seat 102 to achieve folding. In this embodiment, to increase the accommodating area of ​​the frame 10, two X-shaped brackets 101 are provided on each of the left and right sides, and are rotatably connected to each other, thus increasing the length of the frame 10 without affecting folding. It should be noted that an X-shaped support frame (not shown in the figure) is also provided at the bottom of the frame 10. This support frame also adopts a folding design. The four ends of the support frame are rotatably connected to the four connecting seats 102 located at the bottom. When the support frame is folded, it can pull the connecting seats 102 together. The frame 10 is folded down by bringing the wheels together. Four wheels 103 are rotatably connected to the four connecting seats 102 at the bottom. Two wheels 103 at one end are connected to a steering structure 11, which causes the two wheels 103 to rotate synchronously. A tie rod 12 is also connected to the end of the frame 10 with the steering structure 11, and the tie rod 12 can rotate horizontally relative to the frame 10. The bottom of the tie rod 12 is rotatably connected to the steering structure 11. When the tie rod 12 rotates horizontally on the frame 10, it drives the steering structure 11 to move, which in turn drives the wheels 103 to rotate. This allows the orientation of the wheels 103 to be adjusted by rotating the tie rod 12. Simultaneously, the frame... The 10 is equipped with a steering structure 11. A seat device 14 is connected to one end of the steering structure 11. One end of the seat device 14 is rotatably connected to the top connecting seat 102. The seat device 14 can rotate vertically relative to the connecting seat 102. The other end is detachably connected to the X-shaped brackets 101 on the left and right sides. When the frame 10 needs to be folded, the end of the seat device 14 connected to the X-shaped brackets 101 can be separated so that the frame 10 can be folded. When the seat device 14 needs to be used, the seat device 14 is reconnected to the X-shaped brackets 101. The X-shaped brackets 101 support the seat device 14 so that the user can sit on the seat device 14 and control the direction through the lever 12.At least one end of the wheel 103 is a drive wheel equipped with a hub motor, which generates power output when energized to drive the frame 10. The frame 10 also includes a controller (not shown) for controlling the operation of the drive wheel and a power source (not shown) for supplying energy to the drive wheel. Electrification enables the campervan to be ridden.

[0033] It should be noted that, for ease of control, the lever 12 is also electrically connected to the controller, and the lever 12 is equipped with several control buttons (not shown in the figure) for control purposes, such as speed adjustment, start / stop, switching between electric power assist mode and manual mode, etc. Since the campervan has a passenger-carrying function, the drive wheels are 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 in detail here.

[0034] Furthermore, the frame 10 converges from the front, rear, left, and right to the center, and the steering structure 11 includes a plurality of links 111, which are rotatably connected end to end. The first and last ends of the connected links 111 are rotatably connected to the corresponding wheels 103.

[0035] Specifically, the frame 10 is a convergent frame 10. The frame 10 folds inward from the front, back, left and right directions towards the center. In this embodiment, since the frame 10 is convergent, in order to avoid the steering structure 11 restricting the folding of the frame 10, the steering structure 11 includes multiple connecting rods 111 that are rotatably connected end to end. The multiple connecting rods 111 can rotate and fold relative to each other to adapt to the folding of the frame 10. The two ends of the multiple connecting rods 111 after being connected as one unit are rotatably connected to the corresponding wheels 103 at the same end. The movement of the steering structure 11 will drive the wheels 103 to rotate synchronously.

[0036] Furthermore, support rods 121 are rotatably connected to both sides of the bottom of the pull rod 12, and the end of the support rod 121 away from the pull rod 12 is rotatably connected to both sides of the frame 10. The bottom of the pull rod 12 is rotatably connected to the connecting rod 111 located in the middle.

[0037] Specifically, to accommodate the convergent frame 10, support rods 121 are rotatably connected to both sides of the bottom of the tie rod 12. These support rods 121 can rotate vertically relative to the tie rod 12. Simultaneously, the end of the support rod 121 furthest from the tie rod 12 is rotatably connected to a corresponding connecting seat 102. The support rod 121 can also rotate vertically relative to the connecting seat 102. When the frame 10 converges, because the two support rods 121 are rotatable, they are pressed against the connecting seats 102 on both sides of the frame 10, causing them to move towards the connecting seats 102. The pull rod 12 is rotated upwards and lifted up. The pull rod 12 is located outside the end of the frame 10 through the support of the strut 121, and the pull rod 12 can rotate horizontally relative to the strut 121. The bottom of the pull rod 12 is provided with a directional swing arm (not shown in the figure). The pull rod 12 is rotatably connected to the connecting rod 111 in the middle through the directional swing arm. When the pull rod 12 rotates horizontally, it drives the directional swing arm to swing left and right. The directional swing arm drives the connecting rod 111 to move left and right, thereby driving the two wheels 103 to rotate synchronously and achieve steering.

[0038] Furthermore, the two adjacent ends of the two support rods 121 are respectively provided with synchronizing teeth 123, the two synchronizing teeth 123 mesh with each other, the adjacent ends of the two support rods 121 are connected together by connecting kit 122, the bottom of the pull rod 12 is rotatably connected to the connecting kit 122, and the pull rod 12 can rotate horizontally relative to the connecting kit 122;

[0039] Specifically, the two support rods 121 are connected together by the connecting kit 122, and the two support rods 121 can rotate vertically relative to the connecting kit 122. The bottom of the pull rod 12 is located outside the connecting kit 122 and is rotatably connected to the connecting kit 122 by a bearing. Since the two support rods 121 are not directly connected, the rotation angles of the two support rods 121 will be different when rotating, causing the connecting sleeve to tilt, which in turn causes 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 support rods 121. The two synchronous teeth 123 mesh with each other, and the meshing of the gears restricts the rotation of the two support rods 121 to be synchronous and at the same angle, thereby ensuring that the pull rod 12 is always in a vertical state.

[0040] It should be noted that since the two synchronizing teeth 123 are in a meshing state, they are located on the outside of the support rod 121. This causes the ends of the synchronizing teeth 123 to rotate when the support rod 121 rotates, at which point they will press against the connecting kit 122. After being restricted by the connecting kit 122, they cannot continue to rotate, and the frame 10 cannot be fully folded under the restriction of the support rod 121. To avoid this situation, one or two slots corresponding to the synchronizing teeth 123 need to be opened on the connecting kit 122 so that the synchronizing teeth 123 can pass through the connecting kit 122 and are not restricted by the connecting kit 122.

[0041] Furthermore, in this embodiment, the bottom of the pull rod 12 is provided with a folding structure 124, which is used to allow the pull rod 12 to rotate vertically;

[0042] Specifically, to make it easier and less strenuous for the user to tow the vehicle, the bottom of the pull rod 12 is provided with a folding structure 124. This folding structure 124 is used to allow the pull rod 12 to rotate vertically, specifically in the front-to-back direction. This allows the pull rod 12 to tilt forward at a certain angle according to the user's needs 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.

[0043] Among them, such as Figure 3 As shown, the pull rod 12 itself is a telescopic structure, and its length can be changed according to usage requirements. In this case, the folding structure 124 includes: a movable head (not shown in the figure), the movable head is rotatably connected to the connecting kit 122, the movable head can rotate horizontally relative to the connecting kit 122, the directional 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 pull rod 12 can drive the movable head to rotate horizontally, thereby realizing the control of the orientation of the wheel 103.

[0044] Furthermore, the frame 10 is provided with a rotation limiting device 13 at one end of the tie rod 12 to restrict the vertical rotation of the tie rod 12.

[0045] Specifically, in this embodiment, since the frame 10 is capable of carrying passengers, to ensure that the pull rod 12 does not move erratically when carrying passengers, a rotation limiting device 13 is also provided in the middle of the end of the frame 10 where the pull rod 12 is located. This rotation limiting device 13 includes a sleeve 131 and a clamp 132. The sleeve 131 is arc-shaped and fits the pull rod 12. When the pull rod 12 is inside the sleeve 131, the pull rod 12 can also rotate horizontally within the sleeve 131. The clamp 132 and the sleeve 131... The end of the sleeve 131 is rotatably connected, and the other end of the sleeve 131 is also provided with a groove 133. The groove 133 is adapted to the band 132. The band 132 can be inserted into the groove 133. When the pull rod 12 is in the sleeve 131, the pull rod 12 can be restricted from leaving the sleeve 131 by inserting the band 132 into the groove 133. The sleeve 131 is fixedly connected to the frame 10, so it can be ensured that the pull rod 12 is always vertical and will not tilt forward, thus improving the safety of use.

[0046] Furthermore, the clamp 132 is a magnetic metal component, and the clamp groove 133 is also provided with a magnetic component (not shown in the figure). The magnetic component is magnetically attracted to the clamp 132. Specifically, to prevent the clamp 132 from detaching from the clamp groove 133 due to bouncing during travel, the clamp 132 can be made of a magnetic metal component, and a magnetic component, such as a magnet, is installed in the clamp groove 133. When the clamp 132 is inserted into the clamp groove 133, the magnetic attraction between the magnetic component and the clamp 132 further improves the engagement stability of the clamp 132.

[0047] Furthermore, the seating device 14 includes: a mounting rod 141, a pad 142, an extension rod 143, and a transverse support rod 144; there are two mounting rods 141, each of which is rotatably connected to the connecting seat 102 at the same end; the pad 142 is located between the two mounting rods 141, and both ends are connected to the corresponding mounting rods 141; there are two extension rods 143, each of which is rotatably connected to the end of the mounting rod 141 away from the connecting seat 102; there are two transverse support rods 144, each of which is rotatably connected to the corresponding extension rod 143; and the ends of the two transverse support rods 144 away from the extension rod 143 are rotatably connected.

[0048] Specifically, the seat assembly 14 includes two mounting rods 141, which are mounted on the top of the end of the frame 10 where the pull rod 12 is located, and are rotatably connected to the top connecting seat 102, allowing the mounting rods 141 to rotate vertically relative to the connecting seat 102. A pad 142 is disposed between the two mounting rods 141, and its two ends are fixedly connected to the mounting rods 141. The pad 142 is used to support the user. An extension rod 143 is also rotatably connected to the end of the two mounting rods 141 away from the connecting seat 102. The rotatably connected extension rod 143 can be folded up relative to the mounting rods after the frame 10 is folded up. 141 rotates vertically to shorten the overall length, preventing the mounting rod 141 and extension rod 143 from becoming too long after the frame 10 is folded down. The extension rod 143 is used to connect to the X-shaped bracket 101 on the side. The connection method restricts the left and right swing of the extension rod 143, but does not restrict the forward and backward movement or upward movement of the extension rod 143. Thus, the mounting rod 141 is supported by the X-shaped bracket 101, so that the mounting rod 141 will not sink when the user sits on the pad 142. To prevent the mounting rod 141 from tilting in the middle due to the user's weight when sitting on the pad 142, this is to be avoided. In this embodiment, a transverse support rod 144 is rotatably connected between the two extension rods 143. This transverse support rod 144 is divided into two parts, each corresponding to one of the two extension rods 143. The ends of the two transverse support rods 144 furthest from the extension rods 143 are rotatably connected to each other to accommodate the folded state of the vehicle body. When unfolded, the two mounting rods 141 are restricted by the transverse support rod 144, thus preventing them from converging towards the center. When the frame 10 is folded, the forward and backward movement of the frame 10 causes a change in the contact position between the X-shaped bracket 101 and the extension rod 143, causing it to move towards the mounting rod 141. As the extension rod 143 loses the support of the X-shaped bracket 101, it will rotate downward relative to the mounting rod 141. At the same time, the convergence of the left and right sides of the frame 10 will cause the transverse support rod 144 to arch outward from the middle. The outward arching can avoid being restricted by the frame 10 and unable to rotate downward with the extension rod 143. In the converged frame 10, in order to avoid the pad 142 affecting the folding of the frame 10, a flexible material is preferred, which can only generate tension and cannot generate thrust. Since the folding of the frame 10 is towards the middle, the pad 142 will be folded up under the folding of the frame 10 without affecting the folding of the frame 10.

[0049] It should be noted that the mounting rod 141 can also be configured to rotate horizontally as needed, so that when folding, due to the presence of the transverse support rod 144, even if the mounting rod 141 can rotate horizontally, it will not affect the overall use of the seat device 14. Furthermore, the rotation of the mounting rod 141 can help reduce the coverage space of the seat device 14 when the frame 10 needs to be folded, so as to facilitate folding. In addition, the extension rod 143 and the mounting rod 141 can be in a horizontal or vertical state when unfolded.

[0050] Furthermore, a limiting clamp 145 is rotatably connected to the end of the extension rod 143 away from the mounting rod 141. Specifically, since the extension rod 143 is suspended outside the frame 10 via the mounting rod 141 after the frame 10 is folded, any movement or shaking of the frame 10 will cause the extension rod 143 to shake. To avoid this, a limiting clamp 145 is rotatably connected to the end of the extension rod 143 away from the mounting rod 141. This limiting clamp 145 can rotate vertically relative to the extension rod 143. When the extension rod 143 is suspended outside the frame 10, the limiting clamp 145 can be rotated to engage with the telescopic tube of the frame 10, thereby limiting the shaking of the extension rod 143. Since the extension rod 143 will not shake, the frame 10 will be restricted by the extension rod 143 and the mounting rod 141, preventing the frame 10 from unfolding on its own due to shaking.

[0051] Furthermore, in this embodiment, one of the transverse support rods 144 has a relief groove 146 at one end away from the extension rod 143, and the other transverse support rod 144 has a protrusion 147 at one end away from the extension rod 143. The protrusion 147 is adapted to the relief groove 146, and the protrusion 147 is located in the relief groove 146 and rotatably connected to the relief groove 146. A sliding sleeve 148 is slidably provided at one end where the two transverse support rods 144 are connected.

[0052] Specifically, since the two transverse support rods 144 are directly connected, in order to allow the two transverse support rods 144 to rotate relative to each other and to be in a close fit and flat overall when unfolded, a clearance groove 146 is provided at the end of one transverse support rod 144 away from the extension rod 143, and a protrusion 147 is provided on the other transverse support rod 144. The protrusion 147 is inserted into the clearance groove 146 and rotatably connected to the clearance groove 146. By connecting them together through offset, the transverse support rods 144 can be in a close fit and flat overall when unfolded without the need for a connecting piece. At the same time, since the two transverse support rods 144 are rotatably connected, in order to avoid To prevent it from being squeezed and arching on its own, a sliding sleeve 148 is also provided between the two transverse support rods 144. Since the two transverse support rods 144 are connected by offset, they are flat. Therefore, the sliding sleeve 148 can slide between the two transverse support rods 144 without being restricted. Thus, the arching of the two transverse support rods 144 can be restricted by the sliding sleeve 148. In order to prevent the free sliding of the sliding sleeve 148, the sliding sleeve 148 can be made of magnetic metal material, and a magnetic element can be provided on one of the transverse support rods 144. When the sliding sleeve 148 is located at the position of the magnetic element, it can be attracted by the magnetic element, thereby realizing the limiting of the sliding sleeve 148.

[0053] The second embodiment differs from the previous embodiment in that the folding method of the frame 10 is different. The frame 10 in the first embodiment is a convergent type, while the frame 10 in the second embodiment is a folding type. That is, the folding of the frame 10 is limited to the front and rear towards the middle, while the left and right sides are not folded. Therefore, in this state, the corresponding positions are modified. Firstly, the steering structure 11 is set. Since the frame 10 does not need to be brought together from left to right, the steering structure 11 does not need to be folded and can be set as a single integrated link 111 from multiple links 111. Secondly, since the frame 10 does not need to be brought together from left to right, the support rod 121 can also be set as a single integrated shape, and the structure of the synchronizing gear 123 can also be omitted. Thirdly, the pad 142 can be set as a rigid structure, such as a wooden board, and the setting of the transverse support rod 144 can also be omitted. Other structures are the same as in the first embodiment.

[0054] It should be noted that, in both the first and second embodiments, the horizontal rotation center of the tie rod 12 must be on the same straight line as the horizontal rotation center of 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, the movement trajectory of the steering arm and the movement trajectory of the steering structure 11 will be different, resulting in a movement conflict and making it impossible to achieve steering. Alternatively, a groove can be opened on the steering arm so that the connection point between the steering structure 11 and the steering arm can change its relative position, which can also avoid the occurrence of movement conflict.

[0055] In summary, by setting a seat device 14 on the frame 10, this utility model enables the campervan to not only carry cargo but also carry passengers, further enhancing the user experience. It can switch between electric, manual, and passenger modes to better meet different usage needs. In addition, to facilitate steering control while riding, a steering structure 11 is provided between the wheels 103 to simultaneously control the steering of both wheels 103, providing precise steering and contributing to improved user experience and safety.

[0056] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
