The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] 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.

[0034] See attached Figure 1 -Attached Figure 3 The present embodiment also discloses a camping vehicle, which comprises: a vehicle body 6 and a traction handle mounted on the vehicle body 6; the traction handle comprises a handle 1 and a connecting rod 5 connected to each other; the connecting rod 5 is used to connect the vehicle body 6; a switching mechanism 2, an adjustment mechanism 3 and a control circuit board 4 are arranged in the handle 1; the switching mechanism 2 is electrically connected to the control circuit board 4, and the switching mechanism 2 is used to send a first state signal or a second state signal to the control circuit board 4; the adjustment mechanism 3 can be electrically connected to the control circuit board 4, and the adjustment mechanism 3 is used to send an adjustment signal to the control circuit board 4;

[0035] When the control circuit board 4 receives the first state signal input by the switching mechanism 2, the control circuit board 4 is electrically connected to the regulating mechanism 3 and receives the regulating signal from the regulating mechanism 3. The control circuit board 4 controls the vehicle body 6 to perform the preset speed operation according to the regulating signal.

[0036] When the control circuit board 4 receives the second state signal input by the switching mechanism 2, the control circuit board 4 is electrically disconnected from the regulating mechanism 3, and the control circuit board 4 controls the vehicle body 6 to perform a preset braking operation according to the second state signal.

[0037] Specifically, a wheel with a hub motor is installed on the vehicle body 6, and a control circuit board 4 controls and drives the hub motor to control the speed, forward rotation or reverse rotation of the wheel, as well as a battery and other structures that provide power. The handle 1 is composed of two shells that are interlocked with each other. The two shells are interlocked with each other to form an internal cavity to facilitate the installation of the adjustment mechanism 3, the switching mechanism 2 and the control circuit board 4. In order to facilitate the user's holding, an opening is provided in the middle of the handle 1, so that the user can hold the handle 1 with his palm to tow the car; the user holds the handle 1 and controls the speed, forward rotation or reverse rotation of the wheel of the vehicle body 6 by manipulating the adjustment mechanism 3 or the switching mechanism 2 with his fingers. In this embodiment, the adjustment signal and the second state signal have multiple different frequency bands, so that the preset speed operation and the preset brake operation perform corresponding actions. Specifically, the preset speed operation includes forward driving and reverse driving, and the preset brake operation includes first-level deceleration braking, second-level deceleration braking, N-level deceleration braking and trolley braking. In this embodiment, the user pulls the camper car to drive forward, and the user pushes the camper car to drive backward. The control circuit board 4 controls the trolley to perform the corresponding preset speed operation or preset brake operation according to the different signals received.

[0038] In summary, the camper is provided with an independently controlled switching mechanism 2 and an adjusting mechanism 3 on the handle 1. The switching mechanism 2 is controlled to generate a first state signal, so that the adjusting mechanism 3 is connected to the control circuit board 4. The adjusting mechanism 3 is controlled to generate different adjustment signals, so that the camper performs a corresponding preset speed operation. The switching mechanism 2 is controlled to generate a second state signal, which cuts off the electrical connection between the adjusting mechanism 3 and the control circuit board 4. The control circuit board 4 makes the camper perform a corresponding preset braking operation according to different second state signals, thereby solving the problem of poor user experience caused by the single control method of forward, reverse and braking of traditional campers using a single brake start-stop mechanism.

[0039] It should also be noted that a display screen 10 is also provided on the handle 1, and the display screen 10 is electrically connected to the control circuit board 4. The current speed of the camper is displayed through the display screen 10, which is convenient for the user to monitor and control the vehicle speed; the control circuit board 4 can adopt an existing known control circuit, and the control circuit is not described in detail in this embodiment; in other embodiments, a main control board for directly driving the hub motor can also be installed on the vehicle body 6, and the control circuit board 4 serves as a processing board for processing the signals of the regulating mechanism 3 and the switching mechanism 2, and the control circuit board 4 sends a corresponding signal to the main control board on the vehicle body 6, and the main control board on the vehicle body 6 controls the hub motor according to the received signal.

[0040] In order to facilitate the user to operate the adjustment mechanism 3, the adjustment mechanism 3 includes a rotating shaft 30, two dial wheels 31, a first Hall sensor 32 and a first magnet 33; the rotating shaft 30 can be rotatably installed in the handle 1, and both ends of the rotating shaft 30 pass through the handle 1, and a reset torsion spring 34 is provided in the middle of the rotating shaft 30 and connected to the inner wall of the handle 1; the two dial wheels 31 are symmetrically fixed at both ends of the rotating shaft 30; the first Hall sensor 32 is fixed on the inner wall of the handle 1 and is electrically connected to the control circuit board 4; the first magnet 33 is installed on the rotating shaft 30 and is arranged corresponding to the first Hall sensor 32; rotating any dial wheel 31 can make the first Hall sensor 32 generate different adjustment signals.

[0041] Specifically, the adjustment mechanism 3 is distributed at one side end of the handle 1 away from the connecting rod 5, and the axial direction of the rotating shaft 30 is perpendicular to the axial direction of the connecting rod 5, so that when the user holds the handle 1, the thumb can be placed on the dial wheel 31 to turn the dial wheel 31, and the two symmetrical dial wheels 31 are convenient for the user to hold the handle 1 with the left hand or the right hand to control, thereby improving the user experience; in this embodiment, placing the dial wheel 31 at different positions can make the relative positions of the first magnet 33 and the first Hall sensor 32 different, thereby making the Hall sensor generate different adjustment signals, for example, by positively turning the dial wheel 31 The dial 31 can make the first Hall sensor 32 generate a regulation signal for positive acceleration regulation, and the control circuit board 4 controls the camping vehicle to move forward according to the signal. Correspondingly, the driving speed can be set according to the positive adjustment position of the dial 31. On the contrary, by dialing the dial 31 in the reverse direction, the first Hall sensor 32 can generate a regulation signal for negative acceleration regulation, and the control circuit board 4 controls the camping vehicle to move backward according to the signal. When the user does not apply force to the dial 31, the reset torsion spring 34 resets the dial 31 to prevent the camping vehicle from unnecessary acceleration.

[0042] See attached Figure 3The switching mechanism 2 includes a guide rod 20, a connecting seat 21, a reset spring 22, a hand buckle 23, a second Hall sensor 24 and a second magnet 25; the guide rod 20 is fixed in the handle 1, the connecting seat 21 is slidably installed on the guide rod 20, the reset spring 22 is sleeved on the guide rod 20 and connected to the connecting seat 21; one end of the hand buckle 23 is fixedly connected to the connecting seat 21, and the other end of the hand buckle 23 is placed outside the handle 1; the second magnet 25 is installed on the connecting seat 21, the second Hall sensor 24 is fixed on the inner wall of the handle 1 and is arranged corresponding to the second magnet 25, and the second Hall sensor 24 is electrically connected to the control circuit board 4. Specifically, the axial direction of the guide rod 20 is perpendicular to the axial direction of the rotating shaft 30, which is convenient for the user to control the second magnet 25 to be in different positions through the hand buckle 23 with his fingers. Under normal circumstances, the reset spring 22 makes the hand buckle 23 be in a position away from the adjustment mechanism 3, that is, away from the position of the palm of the user holding the handle 1. When it is necessary to make the second Hall sensor 24 generate a first state signal or a different second state signal, the user can move the second magnet 25 along the axial direction of the guide rod 20 by applying force to the palm direction on the hand buckle 23 with his fingers. When the second Hall sensor 24 determines that the position of the second magnet 25 moves away quickly and resets quickly, a first state signal is generated. At this time, the adjustment mechanism 3 is electrically connected to the control circuit board 4. At this time, the user can control the speed through the adjustment mechanism 3 to avoid the user accidentally touching the dial 31 of the adjustment mechanism 3 and causing the camper to start. In actual use, the user can quickly pull the hand buckle 23 and allow the hand buckle 23 to be quickly reset by the reset spring 22; when the user pulls the hand buckle 23 toward the palm position, so that the second magnet 25 is in a different relative position from the second Hall sensor 24, the second Hall sensor 24 generates a different second state signal, and the camper slows down or brakes according to the corresponding preset brake operation.

[0043] In this embodiment, two switching mechanisms 2 are provided, and the two switching mechanisms 2 are symmetrically distributed on both sides of the opening, so that the user can choose to hold the handle 1 with the left hand or the right hand, thereby improving the user experience.
