[0053] like Figure 1-Figure 14 As shown, the utility model provides a new electric camping vehicle capable of carrying people, characterized in that it comprises: a folding body 10, the folding body 10 is a gathering type body and has electric power assistance, a direction rod assembly 20 is further provided outside one end of the folding body 10, an Ackerman steering structure 30 is further provided at one end of the folding body 10 provided with the direction rod assembly 20, the direction rod assembly 20 is also connected to the Ackerman steering structure 30, the wheel 14 at the same end of the folding body 10 and the direction rod assembly 20 is connected to the Ackerman steering structure 30, the Ackerman steering structure 30 is used to generate an angle between the two wheels 14 connected thereto when turning, and the Ackerman steering structure 30 can be folded;

[0054] The two sides of the bottom of the direction rod assembly 20 are also rotatably connected to the direction struts 12 respectively, and one end of the direction struts 12 away from the direction rod assembly 20 is rotatably connected to the folding body 10. The direction rod assembly 20 is suspended outside the folding body 10 through the support of the direction struts 12, and the rotation of the two direction struts 12 is synchronized;

[0055] Specifically, the folding vehicle body 10 is an electric camping vehicle on the market, wherein a vertical rod is provided in the middle of the side support of the folding vehicle body 10, so that a connecting seat can be provided above the middle of the side support, and the connecting seat can prevent it from tilting when folded through the vertical rod, and its folding method is a gathering shape, that is, it gathers toward the middle from the four directions of front, back, left and right. This kind of folding can greatly reduce the space occupied by the vehicle body when not in use, and is also more convenient for storage and carrying. Direction struts 12 are rotatably connected to both sides of the front end of the folding vehicle body 10, and the direction struts 12 can be rotated vertically relative to the folding vehicle body 10 to avoid the folding vehicle body 10 being restricted by the direction struts 12 when folded and unable to be folded; a The steering rod assembly 20 can rotate in situ and vertically. In order to enable the steering rod assembly 20 to directly control the direction of the folding body 10 to improve the safety of use, the two wheels 14 at the front end of the folding body 10 are also connected to the Ackerman steering structure 30. The bottom end of the steering rod assembly 20 is connected to the Ackerman steering structure 30. When the steering rod assembly 20 rotates, the Ackerman steering structure 30 is driven to move left and right. The Ackerman steering structure 30 drives the two wheels 14 to swing left and right to achieve direction control. Due to the cooperation of the Ackerman steering structure 30 and the steering rod assembly 20, the wheels 14 cannot rotate freely. It should be pointed out that in addition to the Ackerman steering structure 30, the In addition to connecting the two wheels 14 together and making them rotate synchronously, it is also used to make the two wheels 14 generate an angle between them when they rotate, rather than being parallel, so as to make the steering of the vehicle body more stable and reduce the wear of the wheels 14; wherein, since the folding vehicle body 10 is a gathering type vehicle body, it will fold in the left and right directions. In order to avoid the Ackerman steering structure 30 limiting the folding of the folding vehicle body 10, the Ackerman steering structure 30 can be folded. When the folding vehicle body 10 is folded, the Ackerman steering structure 30 is folded synchronously. The folding direction can be horizontal folding or vertical folding. In this application, in order to reduce costs and improve the convenience of use, vertical folding is preferred. The folding of the Ackerman steering structure 30 is driven by the direction rod assembly 20. Specifically, when the folding body 10 is gathered and folded, the two direction struts 12 are squeezed. After being squeezed, the direction struts 12 can lift the direction rod assembly 20 upward, so that the direction struts 12 rotate upward under the action of the squeezing force and move upward against the direction rod assembly 20. The direction rod assembly 20 then drives the Ackerman steering structure 30 to move. At the same time, since the Ackerman steering structure 30 itself can be folded in the vertical direction, it can be folded automatically under the drive of the direction rod assembly 20. In order to improve the user experience of the camper, the user's fatigue during use is reduced;In order to improve the user experience of the camper and reduce the fatigue of the user during use, a seat device is also installed above the front end of the folding body 10. The seat device is detachable. When in use, one end can be detachably connected to the connecting seat at the top of the front end of the folding body 10, and the other end can be connected to the side bracket of the folding body 10 through a vertical support rod or connected to the middle of the side bracket through a horizontal support rod, so that the seat device can be supported by the folding body 10 to carry people. When in use, the feet can be stepped on the direction support rod 12, and the direction rod assembly 20 is located between the legs. It can be removed when not in use, and does not affect the folding of the folding body 10. At the same time, in order to avoid the direction rod assembly 20 from swinging left and right when folded or in use, the rotation of the two direction support rods 12 must be synchronous, that is, the two direction support rods 12 can only rotate at the same time when rotating. If one is missing, it will be restricted by the other direction support rod 12 and cannot rotate, so as to ensure that the direction rod assembly 20 can be in a vertical state. ;

[0056] Furthermore, the seat device includes a connecting rod 101. The connecting rods 101 are respectively arranged on both sides of the folding body 10, and at least one connecting rod 101 is arranged on each side. One end of the connecting rod 101 is rotatably connected to the folding body 10, and the other end is clamped with the middle part of the side bracket of the folding body 10. When in use, the connecting rod 101 can be placed on the folding body 10, and the front, back, left, and right movement of the frame of the folding body 10 is limited by the connecting rod 101, so as to improve the stability of the folding body 10 when in use. At the same time, the seat device can be The connecting rod 101 supports passengers, and only needs to detachably fix the seat device on the connecting rod 101; wherein the connecting rod 101 is in two sections, one section is rotatably connected with the folding vehicle body 10, and can be horizontally rotated relative to the folding vehicle body 10, and the two sections of the connecting rod 101 are also rotatably connected and can be rotated vertically. When the connecting rod 101 is horizontally rotated by a predetermined angle, the other section can be hung on the folding vehicle body 10. Through this structure, the connecting rod 101 does not need to be removed when the folding vehicle body 10 is folded, and no additional space is occupied; wherein when the folding vehicle body 10 is folded, the connecting rod 101 is not required to be removed, and no additional space is occupied; A card seat 102 is provided in the middle of the side bracket of the vehicle body 10, and a locking structure is provided on the card seat 102. The locking structure includes a pin shaft, and a locking member 103 is integrally connected to the pin shaft. A tension spring 105 is connected to the bottom of the locking member 103. The tension spring 105 is used to keep the locking member 103 in an inclined state at all times. At the same time, a protrusion 104 is provided on the side of the locking member 103 corresponding to the inclined direction. At the same time, a card slot is provided at the end of the connecting rod 101 away from the rotation connection with the folding vehicle body 10. The size of the locking member 103 is adapted to the card slot. When the connecting rod When 101 is engaged with the pin shaft, the locking piece 103 is located in the connecting rod 101 through the slot, and because the locking piece 103 is inclined and has a protrusion 104, the protrusion 104 will be above the bottom wall of the connecting rod 101 when the locking piece 103 is inclined, thereby limiting the upward rotation of the connecting rod 101 through the protrusion 104. When the lock needs to be released, the pin shaft can be rotated to convert the locking piece 103 from the inclined state to the vertical state. At this time, the protrusion 104 is out of the movement range of the bottom wall of the connecting rod 101, thereby releasing the restriction.

[0057] Further, the direction rod assembly 20 includes: a first folding member 21, a second folding member 22, and a direction rod 23; the first folding member 21 is rotatably connected to the second folding member 22, the second folding member 22 can be vertically rotated relative to the first folding member 21, the first folding member 21 is also rotatably connected to a strut connecting member 212, the first folding member 21 can be horizontally rotated relative to the strut connecting member 212, and the two direction struts 12 are respectively rotatably connected to the strut connecting member 212; the direction rod 23 is slidably arranged in the first folding member 21 and the second folding member 22, and a plurality of control buttons (not shown in the figure) are arranged at the top of the direction rod 23, and the control buttons are connected to the folding body 10 for controlling the electric function of the folding body 10; a direction swing arm 211 is fixedly connected to the bottom of the first folding member 21, and the direction swing arm 211 is connected to the Ackerman steering structure 30; a limiting device 222 for limiting the sliding of the direction rod 23 is also arranged on the second folding member 22;

[0058] Specifically, the first folding member 21 and the second folding member 22 are rotatably connected, the second folding member 22 can rotate vertically relative to the first folding member 21, the first folding member 21 is also rotatably connected to the support rod connecting member 212, the first folding member 21 can rotate horizontally relative to the support rod connecting member 212, the ends of the two direction support rods 12 away from the connection with the folding body 10 are respectively rotatably connected to the support rod connecting member 212, the two direction support rods 12 can respectively rotate vertically relative to the support rod connecting member 212, and because the two direction support rods 12 rotate synchronously, the support rod connecting member 212 will always be in a horizontal state, thereby promoting The first folding member 21 connected thereto is always in a vertical state, and the direction rod 23 is slidably arranged in the first folding member 21 and the second folding member 22. The direction rod 23 can slide in the first folding member 21 and the second folding member 22. The sliding of the direction rod 23 can adjust the height and limit the rotation of the first folding member 21 and the second folding member 22. When the bottom end of the direction rod 23 is located in the first folding member 21, the first folding member 21 and the second folding member 22 cannot rotate under the restriction of the direction rod 23. When the direction rod 23 is separated from the first folding member 21 and located in the second folding member 22, the second folding member 21 and the second folding member 22 cannot rotate. The folding member 22 can be rotated relative to the first folding member 21, so as to change the use state and facilitate towing; wherein, the rotation of the direction rod 23 will drive the second folding member 22 to rotate synchronously, and the second folding member 22 will drive the first folding member 21 to rotate synchronously; due to the sliding setting of the direction rod 23, in order to avoid affecting normal use, a limit device 222 is also provided on the second folding member 22, and the limit device 222 can limit the sliding of the direction rod 23, and the limit device 222 is preferably a spring latch; a plurality of control buttons are also provided on the top of the direction rod 23, and the control buttons are electrically connected to the folding body 10 ... The related functions of the folding vehicle body 10 include but are not limited to: starting, stopping, moving forward, moving backward, horn, light, brake, speed change, etc.; in order to enable the steering rod assembly 20 to drive the Ackerman steering structure 30, a steering swing arm 211 is fixedly connected to the bottom end of the first folding member 21, and the steering swing arm 211 is connected to the Ackerman steering structure 30. When the steering rod 23 rotates, the first folding member 21 is driven to rotate in place, so that the steering swing arm 211 swings to the left or to the right, and the steering swing arm 211 drives the Ackerman steering structure 30 to move to the left or to the right, thereby causing the wheel 14 to rotate to the left or to the right.

[0059] It should be pointed out that since the front end bracket of the folding body 10 is in an "X" shape, when the folding body 10 is folded, the two sides will gather towards the middle. At this time, the steering arm 211 rises under the drive of the steering rod assembly 20. In this case, the front end bracket of the folding body 10 is easy to clamp the steering arm. Under the restriction of the steering arm 211, the folding body 10 cannot be completely folded into place. To avoid this situation, the steering arm 211 can be set to an "S" shape. Since the front end bracket of the folding body 10 is spaced one front and one rear, the "S" design can leave a movement space for the front end bracket of the folding body 10 when the steering arm 211 is at a predetermined height, avoiding interference with the front end bracket of the folding body 10 so that it can be folded into place.

[0060] Furthermore, a chamfer 221 is respectively provided on the same side of one end where the first folding member 21 and the second folding member 22 are connected. Specifically, in order to limit the maximum rotation angle of the second folding member 22 relative to the first folding member 21, a chamfer 221 is respectively provided on the same side where the first folding member 21 and the second folding member 22 are connected. The second folding member 22 can be vertically rotated relative to the first folding member 21 by the setting of the chamfer 221, and after rotating to a certain angle, the further rotation of the second folding member 22 is limited due to the coincidence of the two chamfers 221, and since the second folding member 22 and the other side of the first folding member 21 do not have the chamfer 221, when the second folding member 22 and the first folding member 21 are in a vertical state, the ends of the two are against each other, which will limit the second folding member 22 from rotating in the direction opposite to the chamfer 221, so that the second folding member 22 can only rotate in the direction where the chamfer 221 is located, and is limited after rotating by a predetermined angle, wherein the rotation angle is determined according to the angle of the chamfer 221.

[0061] It should be pointed out that the vertical rotation of the first folding member 21 and the second folding member 22 facilitates the change of the usage mode, such as towing. When the bottom of the steering rod 23 is located in the second folding member 22, the second folding member 22 can drive the steering rod 23 to rotate synchronously, so that the whole is inclined to facilitate towing. When towing, the electric function of the folding body 10 can be controlled to provide assistance.

[0062] Furthermore, in this embodiment, an unlocking device 24 is movably provided in the direction rod 23, and the unlocking device 24 is used to release the restriction of the limiting device 222 on the direction rod 23;

[0063] Specifically, since the limiting device 222 is set on the second folding member 22, the user needs to bend down to pull out the limiting device 222 each time the limit is released, which is not convenient to use. For this reason, an unlocking device 24 is provided in the direction, and the unlocking device 24 can slide vertically in the direction rod 23. One end of the unlocking device 24 passes through the top of the direction rod 23 for the user to press. When the unlocking device 24 slides in the direction rod 23, the unlocking device 24 will move outward against the limiting device 222 to realize the limiting function of releasing the limiting device 222.

[0064] Further, the unlocking device 24 comprises: a movable rod 241, the movable rod 241 is slidably disposed in the direction rod 23, and can slide vertically in the direction rod 23, three unlocking blocks 242 are disposed on the movable rod 241 at a predetermined interval, one side of each unlocking block 242 is sloped, and the top surface of the unlocking block 242 abuts against the inner wall of the direction rod 23, and a return spring 243 is installed at the bottom of the movable rod 241, and the return spring 243 is used to lift the movable rod 241, and the top of the movable rod 241 passes through the direction rod 23;

[0065] Specifically, the movable rod 241 is slidably arranged in the direction rod 23, and in order to limit the movement direction of the movable rod 241, a plurality of collars are arranged in the direction rod 23, and the collars limit the movable rod 241 to move only in the vertical direction. Three unlocking blocks 242 are arranged on the movable rod 241, and the three unlocking blocks 242 move with the movement of the movable rod 241, and the same sides of the three unlocking blocks 242 are respectively sloped, and the unlocking blocks 242 are in contact with the inner wall of the direction rod 23. When the movable rod 241 moves in the direction When the rod 23 slides inside, the unlocking block 242 slides therewith, and the slope of the unlocking block 242 will move outward against the limiting device 222 until the limiting device 222 is separated from the internal space of the direction rod 23. To facilitate the return of the movable rod 241, a return spring 243 is also provided at the bottom of the movable rod 241. When the movable rod 241 is pressed, the movable rod 241 squeezes the return spring 243. When the movable rod 241 loses the squeezing force, the restoring force generated by the return spring 243 will lift the movable rod 241.

[0066] It should be pointed out that a chamfer is also provided on the hole on the direction rod 23 that cooperates with the limit device 222, and the chamfer is located at the outer end of the hole. When the unlocking block 242 squeezes the limit device 222 out of the direction rod 23, due to the limitation of the extrusion stroke, the end of the limit device 222 cannot be completely separated from the direction rod. Therefore, at this time, the limit device 222 still has a limiting effect on the direction rod 23. Under this effect, the direction rod is difficult to slide. The setting of the chamfer can apply a certain force to the direction rod 23 after the unlocking block 242 completes the extrusion work, so that the limit device 222 will be gradually squeezed out of the direction rod 23 under the extrusion of the chamfer, thereby releasing the limiting effect.

[0067] Furthermore, in this embodiment, a grip 25 is provided at the top of the direction rod 23, and the grip 25 and the direction rod 23 form a "T" shape. The two ends of the grip 25 are rotatably connected to folding rods 251, and a handle 252 is slidably sleeved on each folding rod 251. The handle 252 limits the rotation of the folding rod 251. A speed shift finger 26 is provided at one end of the grip 25 away from the folding rod 251, and a brake finger 27 is provided at another end of the grip 25 away from the folding rod 251.

[0068] Specifically, a handle 25 is provided at the top of the direction rod 23, and the handle 25 and the direction rod 23 form a "T"-shaped structure. Folding rods 251 are rotatably connected to the two ends of the handle 25, respectively. The folding rods 251 can be rotated vertically relative to the handle 25 to extend or shorten the length of the handle 25. A handle sleeve 252 is slidably sleeved on each folding rod 251. The handle sleeve 252 can limit the vertical rotation of the folding rod 251 while being convenient for the user to hold. When the folding rod 251 needs to be rotated vertically, the folding rod 251 can be rotated vertically. 1, the handle 252 can be slid to separate it from the connection between the folding rod 251 and the grip 25, and the folding rod 251 can be rotated at this time; in order to adapt to the electric, a speed shift finger 26 and a brake finger 27 are fixedly connected to the grip 25, the speed shift finger 26 is used to control the driving speed of the electric camping car in real time, and the brake finger 27 is used to brake. When the direction rod 23 is installed on the electric camping car, the speed shift finger 26 and the brake finger 27 are connected to the controller of the electric camping car, and the braking method can also be a mechanical brake, such as a drum brake, a disc brake, etc.;

[0069] It should be pointed out that the handle 25 can also be an inverted trapezoid, etc. The specific structure can refer to Chinese Utility Model Patent No. CN202223041748.5. This is the prior art and will not be described in detail here.

[0070] Furthermore, in this embodiment, the folding rod 251 is hollow inside, and an end cap 253 is provided at the tail end of the folding rod 251. A tension spring 254 is connected to the middle of the end cap 253. The tension spring 254 is connected to the folding rod 251. A slide groove 255 is provided on the outer side of the folding rod 251. A slider slidably matched with the slide groove 255 is provided on the inner wall of the handle 252. The end cap 253 is adapted to the handle 252. When the handle 252 slides, the end cap 253 is driven to separate from the folding rod 251.

[0071] Specifically, the interior of the folding rod 251 is hollow. In order to prevent the handle 252 from being separated from the folding rod 251, an end cover 253 is provided at the tail end of the folding rod 251. The end cover 253 is connected to the folding rod 251 through a tension spring 254. The size of the end cover 253 and the handle 252 are adapted. When the handle 252 slides, the end cover 253 will be driven to slide synchronously. At this time, the end cover 253 will pull the tension spring 254 to generate a restoring force. When the handle 252 loses its force, Afterwards, the end cover 253 drives the handle cover 252 to return to its original position under the action of the tension spring 254, and at the same time prevents the handle cover 252 from falling out of the folding rod 251. In order to limit the rotation of the handle cover 252 on the folding rod 251, a slide groove 255 is provided on the outer side of the folding rod 251, and a slider is provided on the inner wall of the handle cover 252. The slider is adapted to the slide groove 255. Through the cooperation of the slider and the slide groove 255, the rotation of the folding rod 251 is limited, and the sliding distance of the handle cover 252 is limited.

[0072] Furthermore, in this embodiment, the top of the direction bar 23 is further provided with an instrument screen 231, and the bottom end of the direction bar 23 is pointed;

[0073] Specifically, in order to facilitate the user to understand the current speed and the remaining power of the electric camper, an instrument screen 231 is rotatably provided at the top of the direction rod 23, and the instrument screen 231 can display relevant information of the current vehicle driving, and the instrument screen 231 can be rotated on the direction rod 23. When the direction rod 23 needs to be stored, the instrument screen 231 can be rotated so that it is attached to the rear or front of the direction rod 23, and the positioning of the instrument screen 231 can be achieved by means of a spring pin; at the same time, in order to facilitate the insertion of the direction rod 23 into the first folding member 21, the bottom end of the direction rod 23 is pointed, and this shape enables the direction rod 23 to slide smoothly into the first folding member 21 even if the second folding member 22 and the first folding member 21 are in a non-vertical state, thereby improving the ease of use.

[0074] Further, in this embodiment, the Ackermann steering structure 30 includes: a first link 31, a second link 32, and a third link 33. There are two second links 32. The first link 31 is located between the two second links 32 and is respectively rotatably connected to the corresponding second link 32. The second link 32 can rotate vertically relative to the first link 31. There are two third links 33, which are respectively located at one end of the second link 32 away from the first link 31 and are respectively rotatably connected to the first link 31. The third link 33 can rotate vertically relative to the second link 32. The first link 31 is connected to the direction rod assembly 20. Wheel swing arms 15 are provided on the front wheels 14. The third link 33 is rotatably connected to the corresponding wheel swing arm 15. The third link 33 can rotate horizontally relative to the wheel swing arm 15. The connection point between the third link 33 and the wheel swing arm 15 is located on the straight line from the horizontal rotation axis of the front wheels 14 to the center of the distance between the two rear wheels 14.

[0075] Specifically, to achieve the folding of the Ackermann steering structure 30, the Ackermann steering structure 30 is composed of one first link 31, two second links 32, and two third links 33. The first link 31 is located between the two second links 32. The third links 33 are located at one end of the two second links 32 away from the first link 31. The first link 31, the second link 32, and the third link 33 are respectively rotatably connected. The first link 31 and the second link 32 can respectively rotate vertically. The second link 32 can also rotate vertically relative to the third link 33. The direction swing arm 211 of the first folding member 21 is rotatably connected to the first link 31. When the direction swings, it drives the first link 31, the second link 32, and the third link 33 to move left and right. Wheel swing arms 15 are provided on each of the front wheels 14 at the front end of the folding vehicle body 10. The third link 33 is rotatably connected to the wheel swing arm 15. The third link 33 can rotate horizontally relative to the wheel swing arm 15. When the third link 33 moves, it pushes or pulls the wheels 14 to rotate horizontally through the wheel swing arm 15. When folding, driven by the direction rod assembly 20, the first link 31, the second link 32, and the third link 33 rotate relative to each other and finally form a "ji" shape. To achieve the effect of Ackermann steering, the connection point between the third link 33 and the wheel swing arm 15 is located on the straight line from the horizontal rotation axis of the two front wheels 14 to the center of the distance between the two rear wheels 14, so that when the two front wheels 14 turn, the rotation angles of the two wheels 14 will be inconsistent, and the steering axes of the two front wheels 14 are located on the axes of the two rear wheels 14, thus achieving the Ackermann steering effect.

[0076] Furthermore, the first connecting rod 31 can be folded horizontally from the middle; specifically, since the angles of the two wheels 14 are inconsistent when they rotate, the positions of the wheel swing arms 15 are also different. At this time, the Ackerman steering structure 30 will be supported under the restriction of the direction swing arm 211, which may affect the Ackerman steering effect. To avoid this situation, the first connecting rod 31 is configured to be foldable horizontally from the middle. Through this structure, the two second connecting rods 32 can respectively drive the corresponding first connecting rods 31 to rotate, thereby avoiding conflicts between the structures and ensuring the steering effect.

[0077] It should be noted that the connecting end of the steering arm 211 and the first connecting rod 31 can be provided with a slide groove 255 according to actual conditions. The provision of the slide groove 255 can make the rotation radius of the steering arm 211 not necessarily equal to the rotation radius of the wheel arm 15.

[0078] Further, in another embodiment, the Ackerman steering structure 30 includes: a first link 31, a second link 32, and a third link 33; two second links 32 are provided, the first link 31 is provided between the two second links 32, the first link 31 is movably connected to the second link 32, the first link 31 is fixedly connected to the bottom of the direction rod assembly 20, the second link 32 can rotate horizontally and vertically relative to the first link 31, the third link 33 is rotatably provided at an end of the second link 32 away from the first link 31, the third link 33 can rotate vertically relative to the second link 32, the third link 33 is also rotatably connected to the corresponding wheel 14, the third link 33 can rotate horizontally relative to the wheel 14, wherein the connection point between the first link 31 and the second link 32 is located on a straight line from the horizontal rotation axis of the two rear wheels 14 to the center of the interval between the two front wheels 14;

[0079] Specifically, the Ackerman steering structure 30 may also adopt another embodiment, that is, it also has a first connecting rod 31, two second connecting rods 32, and two third connecting rods 33, wherein the first connecting rod 31 is also located between the two second connecting rods 32, but is stacked up and down with the second connecting rod 32, and the first connecting rod 31 is connected to the second connecting rod 32 through a transfer shaft 34, wherein the first connecting rod 31 can rotate horizontally relative to the transfer shaft 34, and the second connecting rod 32 can move vertically relative to the transfer shaft 34, and the first connecting rod 31 and the direction swing arm 21 are connected. 1 is a fixed connection, and the swing of the direction swing arm 211 will drive the first connecting rod 31 to move along an arc. When this structure is adopted, the connection point of the first connecting rod 31 and the second connecting rod 32 is located on a straight line from the horizontal rotation axis of the two rear wheels 14 to the center of the distance between the two front wheels 14, and the Ackerman steering effect can also be achieved; the connection method of the first connecting rod 31 and the second connecting rod 32 can also adopt a fisheye bearing or a universal joint. When a fisheye bearing or a universal joint is used, the first connecting rod 31 and the second connecting rod 32 do not need to be stacked up and down.

[0080] Furthermore, in this embodiment, one end of each directional support rod 12 connected to the support rod connecting member 212 is respectively provided with a rack 13, the two racks 13 are meshed, and the support rod connecting member 212 is also provided with an avoidance hole 213 corresponding to the rack 13;

[0081] Specifically, in order to realize the synchronous rotation of the two directional struts 12, a rack 13 is respectively provided at one adjacent end of the two directional struts 12. The rack 13 is arc-shaped and the two racks 13 are meshed. The meshing of the racks 13 will mutually restrict the two directional struts 12 and always maintain equal movement, thereby ensuring that the strut connecting member 212 is always in a horizontal state, and then the direction rod assembly 20 is in a vertical state. Since the direction strut 12 will drive the rack 13 to rotate, the top end of the rack 13 will interfere with the strut connecting member 212 at this time. To avoid this situation, an avoidance hole 213 corresponding to the rack 13 is provided on the strut connecting member 212. When the directional strut 12 rotates, the rack 13 will pass through the outside of the strut connecting member 212 to avoid affecting the rotation of the directional strut 12.

[0082] Furthermore, in the present embodiment, the two directional struts 12 are angled when unfolded. Specifically, the angle between the two directional struts 12 helps to improve the convenience when folding. When folding is required, no human assistance is required, and the two directional struts 12 can be rotated by the squeezing force generated by the folding body 10 itself when folding.

[0083] Further, in the present embodiment, at least one steering drive device 16 is further provided at one end of the folding body 10 provided with the Ackerman steering structure 30, and the steering drive device 16 is transmission-connected with the wheel 14, and the steering drive device 16 is also electrically connected with the folding body 10; specifically, in order to realize the multi-purpose use of the camping car, at least one steering drive device 16 can be further provided at the front end of the folding body 10, and the steering drive device 16 can be a steering gear or a motor with a reduction gearbox, and the steering drive device 16 is arranged at the position where the front wheel 14 is located, and a gear is arranged on the horizontal rotation axis of the front wheel 14, and the steering drive device 16 is transmission-connected with the gear. The steering drive device 16 can be controlled by remote control or follow-up control, and the remote control is used to remotely control the driving of the camping car, and the follow-up control refers to the automatic following of the electric camping car through UWB wireless positioning. Both remote control and follow-up control are existing mature technologies, so the specific control principle is not repeated here. Since the camping car usually carries cargo, the weight of the camping car will be large, and at this time, it will be difficult to control the steering with a single steering drive device 16. At this time, two steering drive devices 16 can be provided to control the two wheels 14 respectively.

[0084] It should be pointed out that when there is only one steering drive device 16, it needs to be coordinated with the Ackerman steering structure 30 so that one steering drive device 16 can control two wheels 14. When there are two steering drive devices 16, since both wheels 14 are controlled by the steering drive device 16, the presence or absence of the Ackerman steering structure 30 depends on the needs. When the Ackerman steering structure 30 is not provided, the rotational speeds of the two steering drive devices 16 need to be different to achieve the Ackerman steering effect.

[0085] Furthermore, in the present embodiment, a limiting clamp 17 is also provided at the front end of the folding body 10, and the limiting clamp 17 is used to limit the vertical rotation of the direction rod assembly 20; specifically, a limiting clamp 17 is also provided on one end of the folding body 10 where the direction rod assembly 20 is provided, and the limiting clamp 17 is used to limit the vertical movement of the direction rod assembly 20, wherein the limiting clamp 17 includes but is not limited to: a clamp (not shown in the figure), a clamping strip (not shown in the figure), one end of the clamping strip is hinged to one end of the clamp, and the other end of the clamp is provided with a clamping groove for the clamping strip to be placed in, and a spring pin is also installed at the end of the clamp where the clamping groove is provided, when the direction rod assembly is placed in the clamping strip, the clamping strip is placed in the clamping groove away from the end hinged to the clamping strip, and the spring pin is used to limit the movement of the clamping strip, thereby limiting the vertical rotation of the direction rod assembly.

[0086] Furthermore, in this embodiment, one end of the folding body 10 provided with the direction rod assembly 20 is also provided with a limiting structure 50 corresponding to the wheel 14, and the limiting structure 50 is used to limit the maximum rotation angle of the wheel 14;

[0087] Specifically, in order to prevent the wheel 14 from being unable to turn back normally due to oversteering during steering, a protruding limiting structure 50 is provided at the bottom connecting seat of the folding body 10. The limiting structure 50 is located on the opposite side of the two connecting seats, and the protruding height needs to be in the movement path of the Ackerman steering structure 30. When the steering rod assembly 20 turns, the wheel 14 is driven to rotate by the Ackerman steering structure 30, and the rotation of the wheel swing arm 15 and the steering rod 23 will synchronously drive the Ackerman steering structure 30 to move in the front and rear directions of the folding body 10. When the wheel 14 rotates to a certain angle, the Ackerman steering structure 30 contacts the limiting structure 50. The Ackerman steering structure 30 is blocked by the limiting structure 50, and the wheel 14 can no longer continue to rotate, thereby limiting the maximum rotation angle of the wheel 14.

[0088] Furthermore, in this embodiment, the wheel 14 connected to the Ackerman steering structure 30 is further provided with a folding rotation limiting structure 40, and the folding rotation limiting structure 40 is used to limit the rotation of the two wheels 14 when the folding vehicle body 10 is in the folded state;

[0089] Specifically, since the wheel 14 is controlled to rotate by the Ackerman steering structure 30, when the folding vehicle body 10 is folded, the Ackerman steering structure 30 is also in a folded state. At this time, the wheel 14 has a certain range of motion due to the shape change of the Ackerman steering structure 30, so that after folding, the wheel 14 rotates under the influence of external force, which easily causes deformation and damage to the Ackerman steering structure 30. In addition, since the wheels are constrained, the folded vehicle body cannot be conveniently towed, thereby affecting the experience. For this reason, the two vehicle bodies connected to the Ackerman steering structure 30 are connected to the Ackerman steering structure 30. The wheels 14 are respectively provided with folding and rotation limiting structures 40 that cooperate with each other. The folding and rotation limiting structures 40 are respectively located on the opposite sides of the two wheels 14. When the folding body 10 is folded, the two wheels 14 move closer to each other, and at the same time, the folding and rotation limiting structures 40 on the two wheels 14 enter a plug-in state. When the folding body 10 is completely folded, the folding and rotation limiting structures 40 cooperate together to limit the rotation of the two wheels 14; when the folding body 10 is unfolded, as the two wheels 14 gradually move away from each other, the folding and rotation limiting structures 40 are out of the plug-in state, and the wheels 14 can rotate normally at this time.

[0090] In summary, the present application provides an Ackerman steering structure on the folding body to stably control the driving direction of the folding body and improve the safety of use. The Ackerman steering structure can create an angle when the two wheels are turning, effectively reducing the wear of the wheels, while improving the stability of the folding body when turning, effectively improving the user experience of the camper and improving the competitiveness of the product. At the same time, the Ackerman steering structure can also be folded to adapt to the folding of the folding body, further improving the practicality.

[0091] 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.
