Description

Technical Field

[0001] The present invention relates to the technical field of battery pack charging, and more specifically to a wireless mutual adsorption charging device formed by combining a Mylar sheet and a magnet. Background Art

[0002] The wireless mutual adsorption charging device formed by combining Mylar sheets and magnets has the function of improving the convenience of charging when charging the battery pack. For this purpose, a wireless design is adopted. The device adopts a wireless design and does not require the use of traditional charging cables, thus avoiding cable damage, entanglement and space occupation problems. Secondly, it has a magnetic attraction function. Through the adsorption of the magnet, the device can be easily docked with the battery pack without the need to accurately align the charging interface, which greatly improves the convenience of charging.

[0003] In the existing public documents, the patent announcement number CN214958755U discloses a safe heat dissipation portable wireless charger. The wireless charging device mainly improves the charging efficiency to a great extent through the cooperation of various components. During the charging process, the heat dissipation fan can quickly take away the temperature in the device to ensure the normal operation of the electronic components in the device, and at the same time, the overall service life of the device is improved to a certain extent. However, the wireless charging device still has the following defects when in use.

[0004] The wireless charging technology formed by the combination of Mylar sheets and magnets can magnetically charge the battery pack of the charged device, but during the charging process, the charging device needs to be in close contact with the battery pack of the charged device for charging. Once other debris is located on the surface of the charging device, the charging device will be directly magnetically attracted to the battery pack of the charged device, not only will a gap be generated to affect the charging efficiency, but the debris is a metal object, which will also generate eddy currents inside the metal object. These eddy currents will cause the metal to heat up, which may cause a fire or damage the equipment in severe cases. It is difficult to perform self-inspection in time, and it is difficult to eliminate the debris in time, resulting in poor safety of battery pack charging. Therefore, the self-inspection and use safety of the charging device are poor.

[0035] In this technical solution, as shown in the attached Figure 9-11 As shown, the fitting and proofreading mechanism includes a pushing micro-electric cylinder 33 fixedly arranged on one side of the ultrasonic sensor 32; a push rod 34 is fixedly connected to the output end of the pushing micro-electric cylinder 33, a push block 35 is fixedly connected to one end of the push rod 34, and a push plate 36 is fixedly installed on the lower surface of the push block 35; a proximity sensor 37 is provided on one side of the push block 35, and the proximity sensor 37 is fixedly connected to the push plate 36, and a second distance sensor 38 is provided on one side of the proximity sensor 37. The cross-sectional shape of the push block 35 is T-shaped, and the second distance sensor 38 is fixedly connected to the inner wall of the push plate 36.

[0036] The working principle of the wireless mutual adsorption charging device formed by combining Mylar sheets and magnets in the present invention is as follows: Step 1: During the lamination proofreading, the linkage micro-electric cylinder 22 is started through the wireless controller 21, and the linkage micro-electric cylinder 22 pushes the linkage shaft 23 upward, and the linkage shaft 23 drives the two limit rings 25 to move upward synchronously, and the limit ring 25 makes the rotating ring 24 move upward, and the rotating ring 24 drives the two linkage columns 26 to move upward synchronously. At the same time, the linkage column 26 drives the turntable 31, and the turntable 31 drives the ultrasonic sensor 32 to move upward, and the turntable 31 drives the micro-electric cylinder 33 to move upward, and the micro-electric cylinder 33 is pushed to make the push rod 34 move upward, and the push rod 34 will drive the push block 35 to move upward, and the push block 35 makes the push plate 36 move upward. At the same time, the push plate 36 drives the proximity sensor 37 to move upward, so that the proximity sensor 37 moves upward along the outer wall of the shell 1 toward the outer wall of the lamination suction cup 3. When the proximity sensor 37 no longer senses the outer wall side of the lamination suction cup 3, the bottom surface of the push plate 36 is higher than the upper surface of the shell 1.

[0037] The wireless controller 21 is used to start the push micro-electric cylinder 33, which pushes the push rod 34 to move right, and the push rod 34 drives the push block 35 to move right. The push block 35 causes the push plate 36 to move right, and the push plate 36 drives the proximity sensor 37 to move right. At the same time, the push plate 36 can drive the second distance sensor 38 to be located on the upper surface of the bonding suction cup 3, and the distance value between the second distance sensor 38 and the bonding suction cup 3 is sensed by the second distance sensor 38. When the sensed distance value is the same as the bonding distance value set by the bus controller 21, the wireless controller 21 is used to turn off the linkage micro-electric cylinder 22 and turn off the push micro-electric cylinder 33, so that the lower surfaces of the push plate 36 and the turntable 31 are higher than the bonding position of the upper surface of the bonding suction cup 3, so that the ultrasonic sensor 32 can move up according to the specified distance and be higher than the bonding position of the upper surface of the bonding suction cup 3, ensuring that the bottom surface of the ultrasonic sensor 32 is higher than the upper surface of the bonding suction cup 3, and accurately calibrating the detection position of the ultrasonic sensor 32.

[0038] Step 2: When detecting the charging debris, the linkage shaft 23 is supported by the linkage micro-electric cylinder 22, and the linkage shaft 23 supports the support column 30. The support column 30 provides support force for the rotating motor 29. The wireless controller 21 starts the rotating motor 29, and the rotating motor 29 drives the transmission rod 28 to rotate 180 degrees clockwise. The transmission rod 28 drives the rotating rod 27 to rotate 180 degrees clockwise. The rotating rod 27 makes one of the linkage columns 26 rotate 180 degrees clockwise, and the linkage column 26 drives the rotating ring 24 to rotate 180 degrees clockwise. The rotating ring 24 rotates 180 degrees clockwise between the two limit rings 25. At the same time, the rotating ring 24 drives another linkage column 26 to rotate 180 degrees clockwise, and the two linkage columns 26 simultaneously drive the rotating disk 31 to rotate 180 degrees clockwise, and the rotating disk 31 causes the ultrasonic sensor 32 to rotate 180 degrees clockwise. In this way, the sensing end of the ultrasonic sensor 32 is higher than the bonding position on the upper surface of the bonding suction cup 3 for sensing, and the ultrasonic sensor 32 can sense the debris on the upper surface of the bonding suction cup 3. When the ultrasonic sensor 32 rotates one hundred and eighty degrees clockwise, the rotating motor 29 is turned off through the wireless controller 21.

[0039] Step 3: When the linkage charging is eliminated, the wireless controller 21 starts the micro-reduction motor 12 at the same time, and the micro-reduction motor 12 drives the screw 7 to rotate forward, and the screw 7 drives the sleeve block 8 to move up under the action of the thread transmission force, and at the same time the sleeve block 8 moves up along the inner wall of the slide frame 6, and the sleeve block 8 drives the connecting bar 9 to move up, and the connecting bar 9 drives the arc plate 10 to move up, and the arc plate 10 makes the rubber pad 11 move up, and the rubber pad 11 drives the induction block 17 to move up. The distance between the first distance sensor 18 and the induction block 17 is sensed by the first distance sensor 18. When the distance value sensed by the first distance sensor 18 is the same as the distance value set by the wireless controller 21, the rubber pad 11 is attached to the height position of the upper surface of the housing 1.

[0040] Then, the micro motor 4 is started by the wireless controller 21, and the housing 1 supports the support block 13, and the support block 13 supports the micro motor 4, so that the micro motor 4 drives the push shaft 5 to rotate counterclockwise, the push shaft 5 drives the slide frame 6 to rotate counterclockwise, the slide frame 6 drives the screw 7 to rotate counterclockwise, the screw 7 makes the sleeve block 8 rotate counterclockwise, the sleeve block 8 drives the connecting bar 9 to rotate counterclockwise, the connecting bar 9 makes the arc plate 10 rotate counterclockwise, and the arc plate 10 makes the rubber pad 11 rotate counterclockwise. The rubber pad 11 can be attached to the upper surface of the fitting suction cup 3 and rotate counterclockwise by 360 degrees, so that the arc plate 10 can remove the debris on the upper surface of the fitting suction cup 3. When the rubber pad 11 rotates 360 degrees counterclockwise and continues to sense the distance to the sensing block 17 through the first distance sensor 18, the micro motor 4 is turned off through the wireless controller 21, and the micro reduction motor 12 is started to drive the screw 7 to reverse, and the sleeve block 8 moves downward under the action of the thread transmission force, and the sleeve block 8 drives the connecting strip 9 to move downward, and the connecting strip 9 drives the arc plate 10 to move the rubber pad 11 downward and reset.

[0041] Step 4: When the wireless battery pack is charging, the linkage micro-electric cylinder 22 drives the linkage shaft 23 to move downward, the linkage shaft 23 makes the two limit rings 25 move downward, the limit ring 25 makes the rotating ring 24 move downward, the rotating ring 24 drives the two linkage columns 26 to move downward, and the linkage column 26 drives the rotating disk 31 to move the ultrasonic sensor 32 downward. At the same time, the wireless controller 21 starts to push the micro-electric cylinder 33 to drive the push rod 34 to move leftward and shrink, the push rod 34 drives the push block 35 to move leftward and shrink, the push block 35 makes the push disk 36 move leftward and shrink, and the push disk 36 drives the proximity sensor 37 and the second distance sensor 38 to move leftward and shrink, so that the upper surface of the ultrasonic sensor 32 is lower than the upper surface of the fitting suction cup 3, and the upper surface of the arc plate 10 is also lower than the upper surface of the fitting suction cup 3, so that the upper surface of the fitting suction cup 3 is kept free of debris.

[0042] The mobile phone device to be charged is placed on the upper surface of the fitting suction cup 3, and is magnetically attracted to the mobile phone device to be charged through multiple magnets 16. The circuit board 15 is powered by the power supply line 19, and the circuit board 15 starts the charging coil 2. The Mylar sheet 14 can perform isolation and insulation operations on the lower surface of the charging coil 2. The charging coil 2 charges the mobile phone device to charge the electric energy into the battery pack of the mobile phone device to complete the wireless charging operation.
