[0034] 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.

[0035] 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.

[0036] See attached Figure 1 -Attached Figure 7The present embodiment also discloses a camping car with wireless power supply and communication, which includes: a car body 1, a traction rod 2, a handle 3, a connecting block 4 and two connecting rods 5; a main control board 10 and a battery 12 for power supply are provided on the car body 1, and the main control board 10 and the battery 12 are electrically connected; one end of the two connecting rods 5 are connected to the connecting block 4, and the other end of the two connecting rods 5 are rotatably connected to the car body 1; a through hole 40 is provided on the connecting block 4, and an output coil 60 is provided in the through hole 40, and a first cable 11 is provided on the car body 1 and any connecting rod 5 to connect the output coil 60 and A main control board 10; one end of the traction rod 2 is connected to the handle 3, and a connecting portion 20 is provided on the other end of the traction rod 2; the traction rod 2 is slidably connected to the connecting block 4, and the traction rod 2 slides along the axial direction of the through hole 40; the traction rod 2 has a working position in which the connecting portion 20 is placed in the through hole 40 and a storage position in which the connecting portion 20 is away from the through hole 40; a receiving coil 61 is provided on the connecting portion 20, and a second cable 22 is provided on the traction rod 2 to connect the receiving coil 61 and the handle 3. When the traction rod 2 is in the working position, the receiving coil 61 and the output coil 60 are inductively coupled to each other and power transmission can be performed.

[0037] Specifically, the vehicle body 1 is provided with a plurality of wheel hubs, and the wheel hubs are provided with wheel hub motors, which are electrically connected to the main control board 10 and the battery 12 through wires, and the main control board 10 issues instructions to control the vehicle speed and steering of the wheel hubs. The main control board 10 is provided with an output power management function to control the power supply and cutoff of the battery 12 to the remaining electronic components; connecting notches are provided on both sides of the connecting block 4, so that one end of the connecting rod 5 can be embedded in the connecting notch, and the connecting rod 5 is rotatably connected to the connecting notch, so that after the connecting rod 5 is removed from the vehicle body 1, the two connecting rods 5 can be put together for storage; the first cable 11 is fixed to the bottom of the vehicle body 1 and the side of any connecting rod 5, through The traction rod 2 is fixed by a strap or a U-shaped buckle, and the traction rod 2 is hollow so that the second cable 22 can be stored and fixed inside the traction rod 2 to avoid interference with the sliding of the traction rod 2 by the second cable 22. The first cable 11 and the second cable 22 are separated from each other and arranged on different components, so that the first cable 11 and the second cable 22 will not be pulled during the repeated sliding of the traction rod 2, thereby solving the problem that the traction rod 2 of the traditional camper is easily damaged by cable pulling during telescopic sliding; the camper can also be provided with a module that can perform near-field communication on the connecting block 4 and the connecting part 20 of the traction rod 2 to realize wireless communication between the main control board 10 and the handle 3.

[0038] In order to enable the main control board 10 to control the power supply of the battery 12 to the handle 3 through the output power management function, an output coil 60 is set on the connecting block 4, and a receiving coil 61 is set on the connecting part 20 of the traction rod 2. The output coil 60 and the receiving coil 61 are both implemented by wireless power supply technology. In this embodiment, the output coil 60 and the receiving coil 61 are both annular structures. The output coil 60 is fixed on the inner wall of the through hole 40, and the receiving coil 61 is fixed on the connecting part 20 of the traction rod 2. The annular structure effectively utilizes the space between the through hole 40 and the traction rod 2, and increases the conversion efficiency between the output coil 60 and the receiving coil 61. In other embodiments, the output coil 60 and the receiving coil 61 can also be designed as a disc-shaped structure, which is not repeated here. When the camper is parked and stationary, the traction rod 2 is in the storage position, that is, the connection portion 20 of the traction rod 2 is away from the through hole 40 and close to the ground. At this time, the output coil 60 and the receiving coil 61 are away from each other, and the handle 3 is disconnected from the main control board 10, so as to avoid the sudden start of the camper when it is parked and used; and when it is necessary to tow the camper for driving, the user pulls the traction rod 2 by holding the handle 3, so that the connection portion 20 of the traction rod 2 is placed in the through hole 40, and the receiving coil 61 overlaps with the output coil 60, so that the main control board 10 controls the power of the battery 12 to be transmitted to the handle 3 through the power output management function, so as to facilitate the user to control the speed, steering and other operations of the camper through the handle 3.

[0039] In general, the wireless power supply and communication camper can separate the first cable 11 and the second cable 22, so that the cable will not be pulled and damaged during the repeated sliding of the traction rod 2 on the connecting block 4, thereby solving the problem that the cables of the traditional camper are easily damaged by pulling, resulting in poor user experience. The output coil 60 is arranged in the connecting block 4, and the receiving coil is arranged on the connecting portion 20 of the traction rod 2, so that when the traction rod 2 is in the working position, the battery 12 on the vehicle body 1 can be controlled by the main control board 10 to stably supply power to the handle 3, ensuring that the main control board 10 on the vehicle body 1 can still control the battery 12 to stably supply power to the handle 3 after the first cable 11 and the second cable 22 are separated. By sliding the traction rod 2 to the storage position, it is convenient to store the traction rod 2 on the vehicle body 1, and the receiving coil 61 and the output coil 60 can be separated from each other to disconnect the power connection. The main control board 10 will actively enter shutdown after reaching the preset time, so that the battery 12 no longer outputs electricity to the outside, avoiding unnecessary power waste caused by the battery 12 still supplying power to the handle 3 when the camper does not need to drive, which can effectively improve the user experience.

[0040] See attached Figure 4A switch sensor 70 is provided on the inner wall of the through hole 40. The switch sensor 70 is electrically connected to the main control board 10 through the first cable 11. A sensing element 71 is provided at the other end of the traction rod 2. The switch sensor 70 senses the main control board 10 by overlapping with the sensing element 71. The main control board 10 is turned on by setting the switch sensor 70 to avoid the main control board 10 from continuously working when the output coil 60 and the receiving coil 61 do not overlap, resulting in self-power consumption. Specifically, the switch sensor 70 is preferably a switch-type Hall sensor, and the sensing element 71 corresponds to an induction magnet. When the other end of the traction rod 2 slides through the inner wall, the sensing element 71 at the other end of the traction rod 2 is inductively coupled to the sensing element 71 installed on the inner wall of the through hole 40. The switch sensors 70 overlap, and the switch sensor 70 turns on the main control board 10 through the change of magnetic induction intensity. In this embodiment, the specific working principle is as follows: under normal conditions, the traction rod 2 is in the storage position, and the main control board 10 is turned off; by pulling the traction rod 2 to the working position, the switch sensor 70 and the induction element 71 overlap to turn on the main control board 10, and because the output coil 60 and the receiving coil 61 are in an overlapping position for power transmission, the main control board 10 is turned on and controls the power of the battery 12 through the first cable 11, the output coil 60, the receiving coil 61 and the second cable 22 to reach the handle 3, so that the handle 3 is powered on, which is convenient for the user to control the camper through the handle 3.

[0041] Furthermore, in order to avoid the situation where the switch sensor 70 continuously senses the sensing element 71 when the connecting portion 20 of the traction rod 2 is placed in the through hole 40, causing the main control board 10 to continuously perform the power-on operation, in the present embodiment, a protrusion is provided at the connecting portion 20 of the traction rod 2, and an elastic barb structure engaged with the protrusion is provided on the connecting block 4, so that the connecting portion 20 can be engaged with the inner wall of the through hole 40; and the switch sensor 70 is installed on the side of the connecting portion 20 away from the handle 3, and the sensing element 71 is installed at the end of the through hole 40 away from the handle 3. The working position of the traction rod 2 includes a sensing position where the sensing element 71 and the switch sensor 70 overlap and a fixed position where the connecting portion 20 and the through hole 40 are engaged with each other. When the traction rod 2 is in the fixed position, the sensing element 71 and the switch sensor 70 are staggered and cannot sense each other. Specifically, during the sliding process of the traction rod 2 from the storage position to the working position, the traction rod 2 first slides to the sensing position. At this time, the switch sensor The sensor 70 and the sensing member 71 overlap with each other, and the main control board 10 is turned on. Finally, the traction rod 2 is placed in a fixed position, that is, the connecting portion 20 of the traction rod 2 is engaged with the through hole 40. At this time, the traction rod 2 cannot be pulled in this direction, so as to achieve a fixed connection between the traction rod 2 and the connecting block 4, ensuring that the traction rod 2 can stably tow the vehicle body 1. At the same time, the sensing member 71 and the switch sensor 70 are staggered with each other, so that the switch sensor 70 cannot sense the sensing member 71 to turn on the main control board 10. Since the main control board 10 itself is in the turned-on state and the output coil 60 and the receiving coil 61 are in an overlapping position, the main control board 10 can operate normally at this time; the switch sensor 70 and the sensing member 71 are staggered with each other, so that when the user controls the main control board 10 to shut down briefly through the handle 3, the switch sensor 70 will not continue to sense the sensing member 71 to cause the main control board 10 to turn on, so that the user can freely choose to turn on or off the main control board 10.

[0042] See attached Figure 4, the connection block 4 is also provided with a first communication module 81, which is electrically connected to the main control board 10 through the first cable 11, and the connection part 20 of the traction rod 2 is provided with a second communication module 82 which can be connected to the first communication module 81 by signal, and the second communication module 82 is electrically connected to the handle 3 through the second cable 22; when the traction rod 2 is in the working position, the first communication module 81 is connected to the second communication module 82 by signal. Specifically, the first communication module 81 and the second communication module 82 are preferably NFC modules, and the main control board 10 and the handle 3 are communicated and transmitted by adopting the near field communication technology, that is, when the traction rod 2 is in the working position, the first communication module 81 and the second communication module 82 overlap each other and transmit data, and the user generates a corresponding command signal by manipulating the handle 3, which is transmitted to the main control board 10 by the second cable 22, the second communication module 82, the first communication module 81 and the first cable 11, and finally the main control board 10 controls the wheel hub motor to perform driving operations such as speed and steering.

[0043] It should be noted that when the traction rod 2 is in a fixed position and the main control board 10 is shut down by the user through the handle 3, the user slides the traction rod 2 to the storage position, and the induction member 71 on the traction rod 2 will definitely make the switch sensor 70 sense again to force the main control board 10 to turn on again. However, when the traction rod 2 is completely placed in the storage position, the receiving coil 61 is far away from the output coil 60, resulting in the output coil 60 being unable to transmit power, and the second communication module 82 is far away from the first communication module 81, resulting in the two being unable to perform near-field communication to achieve data transmission. The main control board 10 will automatically shut down when it cannot obtain the operation signal of the handle 3 within a certain period of time and determines that the output coil 60 and the receiving coil 61 cannot transmit power. Therefore, when the traction rod 2 is in the storage position, the main control board 10 will automatically shut down according to the status of each component, and the output coil 60 and the receiving coil 61 are in a position far away from each other, so that the power of the battery 12 will not be continuously consumed, thereby avoiding unnecessary power waste and improving the user experience.

[0044] In order to facilitate the user to perform driving operations such as speed and steering of the camper through the handle 3, a control component and a signal processing circuit board 31 are provided in the handle 3; the control component is used to input driving operation signals, and the signal processing circuit board 31 is used to receive and process driving operation signals and send operation instructions to the main control board 10; the control component is electrically connected to the signal processing circuit board 31, and the signal processing circuit board 31 is electrically connected to the receiving coil 61 and the transponder through the second cable 22. Specifically, the signal processing circuit board 31 and the main control board 10 can both adopt known control circuits to process the driving operation signals generated by the control component into operation instructions, and send them to the main control board 10. Finally, the main control board 10 controls the hub motor accordingly. In this embodiment, the control component can specifically include a speed dial 32 and a brake handle 33. Both the speed dial 32 and the brake handle 33 have sensors, which are electrically connected to the signal processing circuit board 31 through the sensors. The sensors in the speed dial 32 and the brake handle 33 can adopt Hall sensors, which are electrically connected to the signal processing circuit board 31 through the Hall sensors. The user controls the speed and steering of the camper by adjusting the speed dial 32 and brakes the camper by operating the brake handle 33.

[0045] In addition to the manual control mode described above, the wireless power supply and communication camper also has a remote wireless control mode. In this embodiment, the control component also includes a follower module 34 and a signal transceiver mobile terminal. The follower module 34 is installed in the handle 3 and is electrically connected to the signal processing circuit board 31. The follower module 34 is signal-connected to the signal transceiver terminal. Specifically, the signal transceiver mobile terminal (not shown in the drawings of this embodiment) can be a smart device such as a watch or a mobile phone that can be installed with a control program. The user sends a control instruction to the follower module 34 through the signal transceiver mobile terminal to complete the remote control of the camper. The follower module 34 can specifically be a UWB onboard antenna, a Bluetooth module, a GPS module, etc. In this embodiment, the UWB onboard antenna is preferred. The remote control of the camper is achieved through the high-precision, low-power UWB positioning technology. Specifically, when the traction rod 2 is in a fixed position, the switch sensor 70 does not sense each other with the induction member 71, so that the user can normally remotely turn on or off the camper through the signal transceiver mobile terminal, avoiding the interference of the physical switch with the software switch instruction, which can effectively improve the user's control experience of the wireless power supply and communication camper.

[0046] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments.
