[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] See attached Figure 1 -Attached Figure 6 The present embodiment also discloses an automatic following camping vehicle, which includes a signal transceiver wearable terminal, a vehicle body 1, and a traction handle installed on the vehicle body 1; the traction handle includes a handle 2 and a connecting rod 3 connected to each other; one end of the connecting rod 3 is rotatably connected to the vehicle body 1, and the length of the connecting rod 3 is greater than the height of the vehicle body 1; a following module 4 and a control circuit board 5 are installed in the handle 2, the following module 4 is electrically connected to the control circuit board 5, and the control circuit board 5 is connected to the vehicle body 1 through a wire, and the following module 4 is connected to the signal transceiver wearable terminal signal.

[0041] Specifically, a main control box 10 and two wheel hub motors are provided on the vehicle body 1, and the main control box 10 is snapped onto the bottom of the vehicle body 1, and a main control board 100 is provided inside the main control box 10, and the main control board 100 is electrically connected to the control circuit board 5, and the main control board 100 is electrically connected to the wheel hub motors; the two wheel hub motors are symmetrically installed at the bottom of the vehicle body 1, and the main control board 100 drives the wheel hub motors by receiving signals from the control circuit board 5; the following module 4 can select a UWB onboard antenna, a Bluetooth module, a GPS module or an ultrasonic module, etc., which can have positioning technology to realize ranging following. In this embodiment, the following module 4 preferably adopts a UWB onboard antenna with high precision and low power consumption, and is connected to the signal of the signal transceiver wearable terminal through the following module 4. The user sends a speed adjustment signal, a steering signal, a forward or backward signal, and a close-range signal to the following module 4 through a signal transceiver wearable terminal such as a smart watch. The control circuit board 5 receives and processes the control signals such as the automatic following signal, and finally sends the driving command to the hub motor through the main control board 100, so as to realize the wireless control function of the automatic following camping car. In this embodiment, by installing the following module 4 inside the handle 2 of the connecting rod 3, since the length of the connecting rod 3 is greater than the height of the vehicle body 1, the handle 2 has a large distance from the ground when the connecting rod 3 is perpendicular to the ground or at a certain angle to the ground, so that the following module 4 installed in the handle 2 is not easily disturbed by the ground or objects on the ground, and is not easy to produce multipath effects, thereby improving the positioning accuracy of the following module 4, so that the user can accurately control the automatic following camping car through the signal transceiver wearable terminal or make the automatic following camping car automatically follow, and the installation position of the following module 4 of the automatic following camping car can effectively improve the user experience.

[0042] It should be noted that the known UWB positioning technology, GPS technology, Bluetooth technology, etc. are used between the following module 4 and the signal transceiver wearable terminal. The signal transceiver wearable terminal can be a smart watch (not shown in the drawings of this embodiment). The control circuit board 5 and the main control board 100 use known control circuits, which are not described here. The main control box 10 is also provided with a battery 101 for powering modules such as the hub motor, the main control board 100, and the control circuit board 5. In this embodiment, the connecting rod 3 can adopt a telescopic rod structure, so that the connecting rod 3 can freely adjust the length according to user needs. When the minimum length of the connecting rod 3 is still greater than the height of the vehicle body 1, it is ensured that the following module 4 in the handle 2 maintains a large distance from the ground, thereby reducing the interference of the ground on the following module 4.

[0043] See attached Figure 4The handle 2 is provided with a hand-held portion 20 and a connecting portion 21, and the connecting portion 21 is fixedly connected to the connecting rod 3, wherein the handle 2 is composed of two shells that are buckled with each other, and the two shells are buckled to form a hand-held portion 20 that is convenient for the user to hold and a connecting portion 21 for installing the connecting rod 3. Specifically, the middle of the hand-held portion 20 is provided with an opening to facilitate holding, and the connecting portion 21 is an open hole structure, and the connecting rod 3 is inserted into the hole and is locked and fixed by two bolts; the handle 2 forms an installation cavity 22 between the hand-held portion 20 and the connecting portion 21, and the follower module 4 and the control circuit board 5 are stacked in the installation cavity 22, and the follower module 4 and the control circuit board 5 are spaced apart from each other. By utilizing the area between the hand-held portion 20 and the connecting portion 21, the installation cavity 22 is formed for installing the follower module 4 and the control circuit board 5. By stacking the two, the internal space of the handle 2 can be effectively utilized, making the internal structure of the handle 2 more compact, so that the follower module 4 can be integrated in the handle 2, so that the follower module 4 keeps close to the ground A larger distance can reduce the interference of the ground on the follower module 4; specifically, the bottom wall of the mounting cavity 22 is provided with a low mounting platform 220 and at least two high mounting platforms 221, and the height of the low mounting platform 220 is less than the height of the high mounting platform 221; the low mounting platform 220 is centrally distributed on the bottom wall of the mounting cavity 22, and the follower module 4 is fixed on the low mounting platform 220; at least two high mounting platforms 221 are symmetrically distributed on both sides of the low mounting platform 220, and the control circuit board 5 is mounted on at least two high mounting platforms 221. Through the low mounting platforms 220 and the high mounting platforms 221 of unequal heights, the follower module 4 and the control circuit board 5 are spaced apart from each other to avoid damage caused by uneven heat dissipation caused by direct superposition of the two. Among them, the control circuit board 5 in this embodiment is a U-shaped plate structure, which can perfectly fit the internal shape of the mounting cavity 22 and improve the space utilization rate of the mounting cavity 22; the control circuit board 5 and the follower module 4 are both fixed to the inside of the handle 2 by bolts.

[0044] See attached Figure 4 A display screen 23 is also provided on the handle 2. The display screen 23 is arranged corresponding to the control circuit board 5, and the display screen 23 is electrically connected to the control circuit board 5. Specifically, a hollow digital hole is opened on the handle 2, and a digital display tube is integrated on the control circuit board 5 for displaying the current status of the automatic following camper, including gear speed, battery power, function indication and other information, so as to facilitate the user to monitor the driving status of the camper and control the speed.

[0045] In order to further enhance the user's control over the automatic following camper, the automatic following camper has a manual control mode in addition to the above-mentioned wireless automatic following mode, namely, a speed regulating assembly 6 is provided at the hand-held portion 20 of the handle 2; the speed regulating assembly 6 comprises a rotating shaft 60, two dials 61, a first Hall sensor 62 and a first magnet 63; the rotating shaft 60 is rotatably mounted on a side of the hand-held portion 20 away from the connecting portion 21, and both ends of the rotating shaft 60 pass through the handle 2, a reset torsion spring 64 is provided in the middle of the rotating shaft 60 and connected to the inner wall of the handle 2; the two dials 61 are symmetrically fixed at both ends of the rotating shaft 60; the first Hall sensor 62 is fixed to the inner wall of the handle 2 and is electrically connected to the control circuit board 5; the first magnet 63 is mounted on the rotating shaft 60 and is arranged corresponding to the first Hall sensor 62.

[0046] The speed regulating assembly 6 is distributed at one side end of the handle 2 away from the connecting rod 3, and the axial direction of the rotating shaft 60 is perpendicular to the axial direction of the connecting rod 3, so that when the user holds the handle 2, the thumb can be placed on the dial wheel 61 to turn the dial wheel 61, and the two symmetrical dial wheels 61 are convenient for the user to hold the handle 2 with the left or right hand to control, thereby improving the user experience; in this embodiment, placing the dial wheel 61 at different positions can make the relative positions of the first magnet 63 and the first Hall sensor 62 different, thereby making the first Hall sensor 62 generate different adjustment signals, for example, by positively turning the dial wheel 61, the first Hall sensor 62 can generate a positive acceleration The control circuit board 5 controls the automatic following of the camper to move forward by receiving the adjustment signal generated by the first Hall sensor 62. The corresponding driving speed can be set according to the positive adjustment position of the dial wheel 61. On the contrary, by dialing the dial wheel 61 in the reverse direction, the first Hall sensor 62 can generate an adjustment signal of negative acceleration adjustment. The control circuit board 5 controls the automatic following of the camper to move backward by receiving the adjustment signal generated by the first Hall sensor 62. When the user does not apply force to the dial wheel 61, the reset torsion spring 64 resets the dial wheel 61 to avoid unnecessary acceleration of the automatic following of the camper.

[0047] In order to brake the automatic following camper, the handle 2 is further provided with a switching assembly 7 at the hand-held portion 20; the switching assembly 7 includes a guide rod 70, a connecting seat 71, a return spring 72, a hand buckle 73, a second Hall sensor 74 and a second magnet 75; the guide rod 70 is fixed in the handle 2, the connecting seat 71 is slidably installed on the guide rod 70, the return spring 72 is sleeved on the guide rod 70 and connected to the connecting seat 71; one end of the hand buckle 73 is fixedly connected to the connecting seat 71, and the other end of the hand buckle 73 is placed outside the handle 2; the second magnet 75 is installed on the connecting seat 71, the second Hall sensor 74 is fixed on the inner wall of the handle 2 and is arranged corresponding to the second magnet 75, and the second Hall sensor 74 is electrically connected to the control circuit board 5. Specifically, the axial direction of the guide rod 70 is perpendicular to the axial direction of the rotating shaft 60, so that the user can control the second magnet 75 to be in different positions through the hand button 73 with his fingers. The speed regulating component 6 and the control circuit board 5 can be electrically connected or disconnected through the switching component 7, and the braking operation can be performed through the switching component 7. Specifically, under normal conditions, the reset spring 72 makes the hand button 73 be in a position away from the speed regulating component 6, that is, away from the palm position of the user holding the handle 2. The user can move the second magnet 75 along the axial direction of the guide rod 70 by applying force to the palm direction on the hand button 73 with his fingers: when the second Hall sensor 74 determines that the position of the second magnet 75 is quickly away and quickly reset, the second Hall sensor 74 sends an unlocking signal to the control circuit board 5. At this time, the speed regulating component 6 is electrically connected to the control circuit board 5. When the user touches the dial 61 of the speed regulating component 6 by mistake and causes the automatic following camping vehicle to start, the user can control the speed of the automatic following camping vehicle through the speed regulating component 6 to avoid the situation that the user accidentally touches the dial 61 of the speed regulating component 6 and causes the automatic following camping vehicle to start. In actual use, the user can quickly pull the hand buckle 73 and allow the hand buckle 73 to be quickly reset by the reset spring 72; when the user pulls the hand buckle 73 toward the palm position, so that the second magnet 75 is in a different relative position from the second Hall sensor 74, the second Hall sensor 74 sends a disconnect signal to the control circuit board 5 and the second Hall sensor 74 sends a brake signal with different accelerations to the control circuit board 5 according to the different positions of the second magnet 75. At this time, the speed regulating component 6 is electrically disconnected from the control circuit board 5, and the control circuit board 5 decelerates at different speeds according to the received brake signal and finally brakes.

[0048] There are two switch components 7, and the two switch components 7 are symmetrically distributed on both sides of the opening, which is convenient for the user to choose to hold the handle 2 with the left hand or the right hand, thereby improving the user experience.
