[0003] An existing electric bicycle wireless charging system, such as announcement number CN220242997U, is named an electric bicycle wireless charging system, which includes a charging cabinet and multiple wireless charging modules. The charging cabinet is provided with a monitoring board, a power supply circuit and multiple inverter circuits, the power supply circuit is connected to the multiple inverter circuits, the monitoring board is provided with a wireless communication module, the wireless communication module is connected to the multiple inverter circuits, and the wireless communication module is used to communicate with the communication module on the electric bicycle; each of the wireless charging modules includes a shell and a transmitting coil arranged in the shell, and the transmitting coil of each wireless charging module is connected to a corresponding inverter circuit.

[0004] However, the above wireless charging system only has a charging function, and due to the defects of the electric vehicle's own heat dissipation structure or the influence of ambient temperature, a thermal effect may be generated during charging, causing the battery to heat up, causing certain safety hazards; therefore, we propose an electric bicycle wireless charging temperature rise detection and control device to solve the above problems.

[0006] To achieve the above object, the utility model provides the following technical solution: a temperature rise detection and control device for wireless charging of an electric bicycle, comprising a bottom plate, pillars are installed on both sides above the rear end of the bottom plate, a host is installed on the upper end of the pillar, and a touch screen is installed on the front end of the host;

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model sets a temperature detection and heat dissipation mechanism. During wireless charging, the infrared temperature sensor can provide real-time feedback on the temperature of the power supply housing of the electric bicycle. If the temperature is too high, within the first threshold range, the central processing unit controls the main fan to run for preliminary heat dissipation. If the temperature is too high and reaches the second threshold range, the central processing unit controls four groups of auxiliary fans to run in coordination.

The temperature rise control during the wireless charging process of the electric bicycle is realized, and the problem that the existing wireless charging system only has a charging function, but is affected by the defects of the heat dissipation structure of the electric vehicle itself or the ambient temperature, may produce a thermal effect during charging, causing the battery to heat up, causing certain safety hazards.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-3The utility model provides an embodiment: a temperature rise detection and control device for wireless charging of an electric bicycle, comprising a base plate 1, pillars 2 are installed on both sides above the rear end of the base plate 1, a host 3 is installed on the upper end of the pillar 2, and a touch screen 4 is installed on the front end of the host 3;

[0027] Also includes:

[0028] A card slot 5 is arranged inside the bottom plate 1, a sealing plate 6 is installed inside the card slot 5, a wireless charging transmitter 7 is installed inside the sealing plate 6, and a main fan 8 is installed at a middle position inside the wireless charging transmitter 7;

[0029] A lifting seat 9 is arranged below the sealing plate 6. Auxiliary fans 11 are installed inside the four corners of the lifting seat 9. The lifting seat 9 is connected to the sealing plate 6 via connecting rods 17, and four connecting rods 17 are provided.

[0030] An underground hydraulic lifting column 10 is arranged below the lifting seat 9, and an output end of the underground hydraulic lifting column 10 is transmission-connected to the lifting seat 9;

[0031] An infrared temperature sensor 13, which is mounted on one side of the upper end of the wireless charging transmitter 7;

[0032] The laser distance measuring sensor 14 is installed on both sides of the upper end of the sealing plate 6 .

[0033] See also Figure 2 The upper surface of the lifting seat 9 is provided with an arc-shaped air induction block 12, and the main fan 8 is an exhaust fan blade. When exhausting air downward, the wind encounters the arc-shaped air induction block 12 and can be diffused to the surroundings. When the auxiliary fan 11 runs in coordination, the exhaust and heat dissipation can be accelerated.

[0034] See also Figure 3 A central processing unit 18 is installed inside the host 3. The input end of the central processing unit 18 is electrically connected to the output end of the infrared temperature sensor 13. The output end of the central processing unit 18 is electrically connected to the input ends of the main fan 8 and the auxiliary fan 11. The infrared temperature sensor 13 can provide real-time feedback on the temperature of the power supply housing of the electric bicycle. If the temperature is too high, within the first threshold range, the central processing unit 18 controls the main fan 8 to run for preliminary heat dissipation. If the temperature is too high and reaches the second threshold range, the central processing unit 18 controls the four groups of auxiliary fans 11 to run in coordination to assist the auxiliary fans 11 in dissipating heat. When the temperature remains within the second threshold range without a downward trend, the central processing unit 18 controls the host 3 to stop charging to ensure safety.

[0035] See also Figure 3The input end of the central processor 18 is electrically connected to the output end of the laser ranging sensor 14. The laser ranging sensor 14 is located on both sides of the upper end of the sealing plate 6. When the power receiver part of the battery vehicle is parked at the wireless charging transmitter 7, the two groups of laser ranging sensors 14 can respectively detect the distance from the two points to the bottom shell of the battery vehicle, and feed the data back to the central processor 18. Based on the comparison of the two groups of data and the smaller spacing, the central processor 18 controls the extension of the buried hydraulic lifting column 10, so that the wireless charging transmitter 7 and the bottom shell of the battery vehicle are controlled at a distance of 10 cm to ensure the wireless charging effect.

[0036] See also Figure 2 The upper and lower end surfaces of the main fan 8 and the auxiliary fan 11 are both provided with a protective layer 16, which is a metal mesh with a non-woven fabric layer attached thereto. The metal mesh can isolate large particles of impurities, and the setting of the non-woven fabric layer can ensure the ventilation and heat dissipation effect and prevent moisture from penetrating.

[0037] See also Figure 2 An elastic rubber sealing edge 15 is provided at the edge of the bottom plate 1 . The provision of the elastic rubber sealing edge 15 increases the sealing performance of the periphery when the bottom plate 1 is engaged with the card slot 5 .

[0038] Working principle: When in use, park the battery vehicle horizontally on the base plate 1, so that the power receiver part is close to the wireless charging transmitter 7. After completion, the wireless charging module is controlled by the host 3 touch screen 4. The two groups of laser ranging sensors 14 on the base plate 1 respectively detect the distance from the left and right points to the bottom shell of the battery vehicle, and feed the data back to the central processor 18. Based on the comparison of the two groups of data, the central processor 18 controls the underground hydraulic lifting column 10 to extend based on the smaller spacing, so that the wireless charging transmitter 7 and the bottom shell of the battery vehicle are controlled at a distance of 10 cm to ensure the wireless charging effect. During charging, the infrared temperature sensor 13 can feedback the temperature of the power shell of the electric bicycle in real time. If the temperature is too high, When the temperature is within the first threshold range, the central processor 18 controls the main fan 8 to run for preliminary heat dissipation. If the temperature is too high and reaches the second threshold range, the central processor 18 controls the four groups of auxiliary fans 11 to run in coordination. Both the main fan 8 and the auxiliary fan 11 are exhaust fan blades. When the main fan 8 exhausts air downward, the wind encounters the arc-shaped air induction block 12 and can diffuse to the surroundings. The coordinated operation of the auxiliary fan 11 can accelerate the exhaust and heat dissipation. When the temperature remains within the second threshold range and there is no downward trend, the central processor 18 controls the host 3 to stop charging to ensure safety. After charging is completed, the buried hydraulic lifting column 10 is reset, and the control cover plate 6 is re-engaged in the card slot 5 to make it parallel to the base plate 1 to avoid interference with normal movement.
