Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] See Figure 1 、 Figure 2 and Figure 3 The wireless charging device for an electric scooter shown includes: The charging base 1 is assembled with two or more charging bases adjacent to each other in a horizontal direction. An outer bracket 2, through which a plurality of the charging bases 1 assembled laterally adjacent to each other are mounted. The contact component 3 is mounted on the handlebar 88 of the electric scooter. When charging, the contact component 3 is placed on the charging base 1, and the charging base 1 wirelessly powers the contact component 3. During charging, the electric scooter is lifted off the ground.

[0029] In the above technical solution, the charging base 1 can be assembled and formed according to site conditions and the required number can be spliced.

[0030] The external bracket 2 is used for unified installation. When the external bracket 2 is installed, the charging base 1 maintains a height of 60 cm to 80 cm from the ground.

[0031] The contact assembly 3 is used to upgrade and modify existing electric scooters, and a customized vehicle bar 88 can also be produced based on the contact assembly 3.

[0032] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the charging base 1 includes a body 11, an opening 12 is provided at the front end of the body 11, an electric bolt lock 13 is installed inside the body 11, and the lock tongue of the electric bolt lock 13 is extended to close the opening 12, a groove 14 is provided on the top of the body 11, and an arc groove 15 is provided at the bottom of the groove 14, and the contact component 3 is positioned by the arc groove 15, and a controller is built into the body 11, the opening 12 extends to cross the arc groove 15, and a pressure switch 16 is embedded in the bottom of the arc groove 15, and the pressure switch 16 is connected to the controller, an indicator light 17 is integrated on the top of the body 11, and the controller is connected to control the indicator light 17; a card reader 18 is embedded in the front end of the body 11, and the card reader 18 is connected to the controller. 1 is embedded with an electric push rod 19, which is also connected to the controller, and a wireless transmitter 110 is installed at the movable end of the electric push rod 19; when charging, the pole of the electric scooter enters through the opening 12. After entering, the electric scooter is lowered so that the contact component 3 is positioned in the arc groove 15. The pressure switch 16 is triggered by pressing the contact component 3. The pressure is kept for more than 3 seconds. The controller confirms that the contact component 3 has been placed. At this time, the indicator light 17 is always green. The user draws electricity by swiping the card. When the power is drawn, the indicator light 17 flashes green, indicating that charging is in progress; when charging is completed, the indicator light 17 is always yellow; side covers 111 are detachably installed at both ends of the body 11, and connectors 21 are installed between adjacent side covers 111 and between the side covers 111 and the outer bracket 2.

[0033] In the above technical solution, the controller is a controller with a built-in wireless communication module, which integrates the card swiping function and the network function.

[0034] Users can pay by swiping a card or scanning a QR code to settle the charge.

[0035] In the above technical solution, the arc-shaped groove 15 can realize the rapid positioning of the contact component 3. During the positioning, the pressure switch 16 is used to determine whether it is placed in place.

[0036] When the user is actually using the electric scooter, he only needs to lift the handle of the electric scooter, and then use the weight of the electric scooter to push the contact assembly 3 downward to trigger the pressure switch 16 and complete the activation of the controller.

[0037] Then you can draw electricity by swiping the card.

[0038] See Figure 4 As shown, ventilation slots 121 are provided at the front and rear end surfaces of the body 11, and an opening is provided at the bottom of the body 11, which is connected to the inner cavity of the body 11, and a cooling fan is installed at the opening; a temperature sensor is integrated inside the body 11, and the temperature sensor and the cooling fan are both connected to the controller. When charging is started, the cooling fan starts to work, and the speed of the cooling fan gradually increases as the temperature monitored by the temperature sensor rises.

[0039] When the temperature inside the main body 11 is less than 45°C, natural convection + 30% fan speed is used.

[0040] When the temperature inside the main body 11 is 45-60°C, the fan speed is 50%.

[0041] When the temperature inside the main body 11 is greater than 60°C, 100% fan speed is used and charging power is derated by 50%.

[0042] The above technical solution is mainly to prevent the temperature inside the body 11 from being too high.

[0043] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the contact component 3 has a cylindrical clamping component 31, and a wireless receiving end 32 is elastically mounted through the clamping component 31. The clamping component 31 is clamped on the handle of the electric scooter. The clamping component 31 fits into the arc groove 15. When the clamping component 31 falls into the arc groove 15, it presses the pressure switch 16.

[0044] The cylindrical clamping assembly 31 is used to facilitate adaptation to the arc-shaped groove 15 to complete the alignment of the wireless receiving end 32 and the wireless transmitting end 110.

[0045] See Figure 5 、 Figure 6 and Figure 7As shown, the clamping assembly 31 includes a clamping rod 310, a backing plate 311, a clamping cap 312, a housing 313 and a shield 314; the clamping rod 310 has a U-shaped clamping groove 315, and the end of the clamping rod 310 away from the clamping groove 315 is provided with a cover plate 316, the clamping groove 315 passes through in a direction away from the cover plate 316, and the outside of the clamping rod 310 is processed with a threaded portion 317; the backing plate 311 has a through hole 318 that passes through the clamping rod 310, and the backing plate 311 has a positioning groove 319 for positioning the lathe rod 88, and the clamping rod 310 is provided with a U-shaped clamping groove 315. 10 passes through the through hole 318 and is threadedly connected to the clamping cap 312; a threading hole 320 is processed at the axis of the clamping rod 310, and the wire harness 99 connected to the wireless receiving end 32 passes through the threading hole 320, and the housing 313 and the cover plate 316 are assembled to form a seal; a partition 321 is fixedly installed inside the housing 313, and a first threading hole 322 is eccentrically provided at the partition 321, and the wire harness 99 connected to the wireless receiving end 32 passes through the first threading hole 322; more than two guide holes 323 are distributed in an annular manner on the plate surface of the partition 321, and the wireless The back of the wireless receiving end 32 is integrated with a guide rod 324, which is fitted with a limit cap 325 after passing through the guide hole 323. A spring 326 is sleeved on the guide rod 324, and the spring 326 acts between the partition 321 and the wireless receiving end 32; the shield 314 is fixed to the end of the housing 313 away from the cover 316; an assembly hole 327 is provided at the axis of the shield 314, and the aperture of the assembly hole 327 is smaller than the diameter of the wireless receiving end 32; the aperture of the assembly hole 327 is larger than the outer diameter of the wireless transmitting end 110, and the assembly hole 327 is provided at the center of the axis of the shield 314. The outer diameters of the clamping cap 312, the pad 311, the housing 313 and the shield 314 are consistent and all fit with the arc groove 15; when the clamping assembly 31 fits with the arc groove 15, the wireless transmitting end 110 is coaxial with the wireless receiving end 32, and after the electric push rod 19 is pushed out, the wireless transmitting end 110 enters through the assembly hole 327 and contacts the wireless receiving end 32; through the compression of the spring 326, the wireless receiving end 32 is given a retreat to ensure effective contact between the wireless receiving end 32 and the wireless transmitting end 110, and when the controller in the main body 11 detects that the circuit is turned on, the indicator light 17 flashes green.

[0046] In the above technical solution, the quick installation with the vehicle rod 88 can be achieved through the cooperation of the clamping rod 310, the backing plate 311 and the clamping cap 312.

[0047] During installation, a hole is drilled on the vehicle rod 88, and then the wiring harness 99 of the wireless receiving end 32 is connected to the original charging controller of the electric scooter. Then, the clamping rod 310 is passed through the pad 311 and then threadedly connected to the clamping cap 312 to complete the clamping work.

[0048] Under normal conditions, the wireless receiving end 32 is pushed outward by the elastic action of the spring 326 and then presses against the blocking cover 314 , so that the wireless receiving end 32 forms a seal with respect to the assembly hole 327 , thereby preventing water from entering, especially when used in rainy days.

[0049] When charging is needed, the wireless transmitting terminal 110 is pushed out by the electric push rod. After being pushed out, the wireless transmitting terminal 110 contacts the wireless receiving terminal 32 and pushes the wireless receiving terminal 32 into the extension of the housing 313. The first is to ensure effective contact between the wireless transmitting terminal 110 and the wireless receiving terminal 32, and the second is to provide a channel for subsequent heat dissipation.

[0050] See Figure 3 and Figure 6 As shown, a sealed terminal 3201 is embedded at the axis of the wire threading hole 320, and the wiring harness 99 connected to the wireless receiving end 32 passes through the sealed terminal 3201 and is interference fit with the sealed terminal 3201. The sealed terminal 3201 is interference fit with the wire threading hole 320, and a sealing gasket 3202 is injection molded on the outer wall of the sealed terminal 3201. During installation, a mounting hole with the same aperture as the wire threading hole 320 is drilled on the vehicle rod, and the sealed terminal 3201 is embedded in the mounting hole. At this time, the sealing gasket 3202 is clamped between the vehicle rod and the clamping groove 315.

[0051] In the above technical solution, the sealed terminal 3201 has four sealing effects.

[0052] First, the sealed terminal 3201 is inserted into the wire hole 320 to form a seal with the wire hole 320 .

[0053] Second, the wire harness 99 passes through the sealed terminal 3201 , and a seal is also formed between the wire harness 99 and the sealed terminal 3201 .

[0054] Third, the sealing terminal 3201 is inserted into the mounting hole provided on the vehicle bar 88 , and forms a seal with the vehicle bar 88 .

[0055] Fourth, the injection molded sealing gasket 3202 forms a seal between the turning rod 88 and the clamping groove 315 after the clamping cap 312 is tightened.

[0056] Through the above-mentioned four-fold sealing effect, the threading position of the vehicle rod 88 is effectively sealed to avoid the problem of water ingress inside.

[0057] See Figure 6 and Figure 7As shown, a ventilation hole 3101 is axially penetrated at the end face of the clamping rod 310, a first mounting hole is penetrated at the center of the partition 321, and a built-in fan 3102 is installed in the first mounting hole. The built-in fan 3102 blows air toward the wireless receiving end 32. When the built-in fan 3102 is started, a negative pressure is formed at the ventilation hole 3101; the built-in fan 3102 is connected to the wireless receiving end 32, and when the wireless receiving end 32 is connected to the wireless transmitting end 110, the built-in fan 3102 is electrically started; the clamping cap 312 is away from the pad 311 A stepped hole 3120 is processed at that end, and a first cover plate 3121 is detachably installed at the stepped hole 3120, and a metal filter 3122 is installed at the axis of the first cover plate 3121; the outer diameter of the wireless receiving terminal 32 is smaller than the inner diameter of the housing 313. When the wireless receiving terminal 32 is pushed in by the wireless transmitting terminal 110, the cold air blown out from the built-in fan 3102 passes through the outside of the wireless receiving terminal 32, and is then discharged along the gap between the wireless transmitting terminal 110 and the assembly hole 327, taking away the heat at the contact position between the wireless receiving terminal 32 and the wireless transmitting terminal 110.

[0058] In the above technical solution, when the wireless transmitting terminal 110 is inserted, the wireless receiving terminal 32 is pushed away, so that a gap is formed between the outer side of the wireless receiving terminal 32 and the inner wall of the casing 313. When the built-in fan 3102 is started, negative pressure is generated at the metal filter 3122, sucking in the external normal temperature airflow, and the airflow acts on the wireless receiving terminal 32, and then blows it out from the assembly hole 327, taking away the heat of the wireless transmitting terminal 110 when blowing it out.

[0059] See Figure 7 As shown, an aluminum heat exchange plate 3221 is integrated at the end surface of the wireless receiving end 32 away from the wireless transmitting end 110 , and the air outlet direction of the built-in fan 3102 is facing the aluminum heat exchange plate 3221 .

[0060] The aluminum heat exchange plate 3221 can increase the heat conduction effect, transfer the heat of the wireless receiving end 32, and then achieve effective heat dissipation after contact with the cold air blown by the built-in fan 3102.

[0061] See Figure 6 As shown, a drainage hole 3123 is eccentrically provided on the plate surface of the first cover plate 3121 , and the water entering from the metal filter 3122 is discharged through the drainage hole 3123 , and a rubber plug 3999 is inserted in the drainage hole 3123 .

[0062] The mesh of the metal filter 3122 is dense, and conventional rainwater cannot enter. In addition, when the electric scooter is in use, the metal filter 3122 is perpendicular to the ground, so the water inflow rate is low.

[0063] However, considering that water may enter the vehicle when it is parked in the open air and encounters heavy rain, we have designed the drainage hole 3123 to actively open the rubber plug 3999 to drain the water after the heavy rain.

[0064] The workflow of the present invention is: 1) The rod 88 enters through the opening 12 and the contact assembly 3 falls into the arc-shaped groove 15; 2) The pressure switch 16 is triggered and the indicator light 17 turns green; 3) Swipe the card to draw power, and the electric push rod 19 pushes out the wireless transmitter 110; 4) The wireless transmitter 110 and the wireless receiver 32 come into contact and charge; 5) The built-in fan 3102 starts to dissipate heat; 6) Charging is complete and indicator light 17 turns yellow.

[0065] The basic principles, main features, and advantages of the present invention are shown and described above.
