[0020] (III) Beneficial effects

[0021] 1: This high-efficiency fast charging device with overvoltage protection realizes fully automated operation of battery charging, from the initial placement of the battery, plug insertion, to the establishment of the charging connection, and then to overvoltage protection and heat dissipation regulation during the charging process. The entire process reduces manual intervention and reduces the risks that may be caused by human operational errors. The fully automated operation not only improves the charging efficiency, saves time and labor costs, but also ensures the accuracy and consistency of each charge, providing users with a convenient and reliable charging experience.

[0022] 2: During the charging connection process, the arc-shaped contact piece can be accurately and tightly connected to the battery pole through the precise mechanical transmission and coordinated cooperation of the motor, threaded rod, push plate, contact plate, slide rod, bidirectional threaded rod and other components. This stable connection method forms a stable charging circuit, which greatly reduces the risk of energy loss, heat and charging failure caused by poor contact. The stable charging circuit ensures the smooth transmission of current, improves the quality and efficiency of charging, and also reduces damage to batteries and charging equipment, extending their service life.

[0023] 3. The overvoltage detection module in the device can monitor the input and output voltages in real time and accurately. Once it detects that the voltage exceeds the preset safety threshold, the control module will respond quickly and take effective protection measures, such as cutting off the power input, adjusting the working status of the voltage conversion module or issuing an alarm. This mechanism effectively protects the charging equipment and batteries from damage caused by overvoltage, avoiding equipment failure, shortened battery life and even safety accidents caused by overvoltage. The overvoltage protection function extends the service life of the charging equipment and batteries, reduces maintenance and replacement costs, and enhances the safety and reliability of the charging process.

[0024] 4: The ingenious design of the heat dissipation vent and U-shaped cover plays an important role in the charging process. When charging starts, the U-shaped cover automatically moves away to open the heat dissipation vent. The internal cooling fan can quickly discharge the heat generated by charging, effectively reducing the temperature inside the device. Good heat dissipation helps to maintain the stable performance of electronic components, reduce component aging and failure due to overheating, and extend the service life of the device. After charging is completed, the U-shaped cover automatically resets to block the heat dissipation vent to prevent dust and debris from entering the device, keeping the inside of the device clean and dry, reducing the risk of short circuit and failure due to dust accumulation, improving the reliability and stability of the equipment, and reducing the frequency of maintenance and cleaning.

[0025] 5. The frame set on the base and the protective shell on the upper end provide an orderly wiring channel for the connecting wires. The connecting wires can be stretched and bent normally under the restriction of the protective shell, avoiding excessive swinging of the wires and entanglement with other components during use. This neat and orderly wiring method reduces the possibility of short circuits, open circuits and other faults caused by chaotic wires. Good wiring management helps to improve the overall safety of the equipment, reduce safety hazards caused by line problems, and ensure the stability and reliability of the charging process.

Each protrusion 72 is slidably installed in the slide groove three 45 respectively. The two racks 71 are located above the contact plate 61 and the slide rod 44. The round rod 68 movably passes through the T-bar 7. The T-bar 7 is fixedly connected to the inner wall of the slide groove four 67 through a spring 69. The two slide rods 44 are fixedly connected through the contact plate 61 and the rectangular plate 65. A push block 63 is fixedly installed on the upper end of the push plate 62. The push block 63 corresponds to the position of the contact block 73. The push block 63 and the contact block 73 are both designed in a triangular shape. A baffle 15 is fixedly installed on the upper end of the base 1. The baffle 15 is located on one side of the placement groove 11. The upper end of the base 1 is fixedly installed with a frame 8, a U-shaped baffle The cover 64 movably penetrates the frame 8, and a protective shell 81 for limiting the connection wire 32 is provided at the upper end of the frame 8. When charging the battery 12, the plug 29 is inserted into the socket, the battery 12 is placed in the placement groove 11, and the motor 5 is started to rotate the threaded rod 51, and the push plate 62 is driven to move by the rotation of the threaded rod 51. The contact plate 61 is exerted with a force by the movement of the push plate 62, so that the contact plate 61 drives the two slide bars 44 to move closer to the battery 12, so that the two insulating plates 4 reach the top of the battery pole of the battery 12. At this time, each two arc-shaped contact pieces 33 are respectively located on both sides of the two battery poles, and the two arc-shaped contact pieces 33 move closer to the battery poles and are tightly connected to realize the electrical connection between the battery poles and the connection wires 32, thereby realizing The battery 12 is electrically connected to the charging device body 2, and the battery 12 can be charged by using the charging device body 2, realizing the automatic start of the charging connection, reducing the possibility of manual intervention and operating errors, and is installed in the device housing 21 through the circuit board 22. The circuit board 22 is equipped with a power input module 23, a voltage conversion module 24, a charging output module 25, an overvoltage detection module 26 and a control module 27. The power input module 23 is responsible for receiving the input of the external power supply and introducing the electric energy into the charging device. The voltage conversion module 24 converts the input power voltage and adjusts it to a voltage value suitable for charging the battery 12. The charging output module 25 transmits the converted voltage to the battery 12 to realize the charging function. The overvoltage detection module 26 is in real time. Monitor the input voltage and output voltage. When it is detected that the voltage exceeds the set safety threshold, the signal is transmitted to the control module 27.

Specifically, the motor 5 controls the threaded rod 51 to rotate, and the threaded rod 51 rotates to drive the push plate 62 to move. The movement of the push plate 62 will apply a force to the contact plate 61, so that the contact plate 61 moves. The movement of the contact plate 61 drives the two slide bars 44 and the two insulating plates 4 to move closer to the battery 12. When the two arc-shaped contact pieces 33 are located on both sides of the battery pole,At this time, the push plate 62 has been completely misaligned with the contact plate 61. At this time, the threaded rod 51 continues to rotate, and the push plate 62 will continue to move to the rectangular plate 65. At this time, the positions of the contact plate 61 and the insulating plate 4 will not change, and a balanced state will be maintained. The continued movement of the push plate 62 will cause the push block 63 on the push plate 62 to apply a force to the contact block 73, so that the T-bar 7 moves, and the movement of the T-bar 7 drives the two racks 71 to move. The movement of the two racks 71 drives the two gears 43 to rotate, so that the two bidirectional threaded rods 42 rotate, and the two bidirectional threaded rods 42 respectively drive each two insulating rods 34 to move closer to each other, so that each two arc-shaped contact pieces 33 move closer to each other, thereby achieving contact with the battery 12 The battery poles on the upper and lower parts are closely connected, so that the positive and negative battery poles are stably electrically connected with the two connecting wires 32 to form a complete closed loop, and the charging device body 2 can charge the battery 12, ensuring a close and stable connection between the arc-shaped contact piece 33 and the battery pole. The precise and orderly mechanical transmission process ensures the reliability and stability of the charging connection and reduces the risk of charging failure caused by poor connection. When the push plate 62 moves, it will drive the U-shaped blocking cover 64 to move, so that the U-shaped blocking cover 64 slides at the heat dissipation vent 28, that is, when the battery 12 is charged, the U-shaped blocking cover 64 no longer blocks the heat dissipation vent 28. When the battery 12 is charged, the U-shaped blocking cover 64 moves in the opposite direction to reset, so that the U-shaped blocking cover 64 4 continues to block the heat dissipation vent 28. The heat dissipation fan 31 is located on one side of the dustproof net 3 and is used to discharge the heat in the charging device body 2 to achieve the heat dissipation effect. The heat dissipation channel is opened in time during the charging process to effectively reduce the temperature inside the charging device body 2, avoid damage to electronic components caused by overheating, and extend the service life of the device. After charging is completed, the heat dissipation vent 28 is blocked in time to prevent dust and debris from entering the inside of the device, keep the inside of the device clean and dry, and help improve the reliability and stability of the device. It is fully automatically opened or closed, and no operator needs to operate alone, which is more convenient to use. It is slidably installed in the slide groove 4 67 through the bottom of the T-bar 7. The round rod 68 movably penetrates the T-bar 7 to connect the T-bar 7 and the two racks. The movement of 71 plays a limiting role. The T-bar 7 is fixedly connected to the inner wall of the slide groove 4 67 through the spring 69. When the push block 63 no longer applies force to the contact block 73, the elastic reset effect of the spring 69 is used to reset the T-bar 7 and the two racks 71. The arc contact piece 33 is reset by resetting the two racks 71, and the connection with the battery pole can be released, realizing the automatic separation of the arc contact piece 33 and the battery pole after charging is completed, simplifying the operation process, improving work efficiency, and having a reasonable structural design. A frame 8 is fixedly installed on the upper end of the base 1, and a protective shell 81 is fixedly connected to the upper end of each frame 8. Each connecting wire 32 passes through the protective shell 81 respectively, and each protective shell 81 is used to limit the connecting wire 32.While ensuring the normal expansion and contraction of the connecting wires 32, the two connecting wires 32 are prevented from being entangled with other components, ensuring the neatness and orderliness of the internal wiring of the equipment, improving the overall safety and stability of the equipment, and reducing the possibility of failures caused by line confusion.

[0041] Working principle:

[0042] The first step is to charge the battery 12 by inserting the plug 29 into the socket, placing the battery 12 in the placement slot 11, and starting the motor 5 to rotate the threaded rod 51. The threaded rod 51 rotates to drive the push plate 62 to move. The push plate 62 moves to apply a force to the contact plate 61, so that the contact plate 61 drives the two slide bars 44 to move closer to the battery 12, so that the two insulating plates 4 reach the top of the battery poles of the battery 12. At this time, each two arc-shaped contact pieces 33 are respectively located on both sides of the two battery poles, and the two arc-shaped contact pieces 33 move closer to the battery poles and are tightly connected to the battery poles, so that the battery poles are electrically connected to the connecting wires 32, thereby realizing the electrical connection between the battery 12 and the charging device body 2. The charging device body 2 can be used to charge the battery 12, and the automatic start of the charging connection is realized, which reduces the possibility of manual intervention and operating errors.

[0043] The circuit board 22 is installed in the device housing 21. The circuit board 22 is equipped with a power input module 23, a voltage conversion module 24, a charging output module 25, an overvoltage detection module 26 and a control module 27. The power input module 23 is responsible for receiving the input of the external power supply and introducing the electric energy into the charging device. The voltage conversion module 24 converts the input power voltage and adjusts it to a voltage value suitable for charging the battery 12. The charging output module 25 transmits the converted voltage to the battery 12 to realize the charging function. The overvoltage detection module 26 monitors the input voltage and output voltage in real time. When it is detected that the voltage exceeds the set safety threshold, the signal is transmitted to the control module 27. The control module 27 takes control measures in time according to the received overvoltage signal, such as cutting off the power input, adjusting the working state of the voltage conversion module 24 or issuing an alarm, so as to protect the charging device body 2 and the battery 12 from overvoltage damage.

[0044] In the second step, specifically, the motor 5 controls the threaded rod 51 to rotate, and the threaded rod 51 rotates to drive the push plate 62 to move. The movement of the push plate 62 will apply a force to the contact plate 61, so that the contact plate 61 moves, and the movement of the contact plate 61 drives the two slide bars 44 and the two insulating plates 4 to move closer to the battery 12. When the two arc-shaped contact pieces 33 are located on both sides of the battery pole, the push plate 62 is completely misaligned with the contact plate 61. At this time, the threaded rod 51 continues to rotate, and the push plate 62 will continue to move to the rectangular plate 65. At this time, the positions of the contact plate 61 and the insulating plate 4 will not change, and a balanced state will be maintained. The continued movement of the push plate 62 will cause the push block 63 on the push plate 62 to apply a force to the contact block 73, so that the T-bar 7 moves. The movement of the T-shaped rod 7 drives the two racks 71 to move, and the movement of the two racks 71 drives the two gears 43 to rotate, so that the two bidirectional threaded rods 42 rotate, and the two bidirectional threaded rods 42 respectively drive each two insulating rods 34 to move closer to each other, so that each two arc-shaped contact pieces 33 move closer to each other, thereby achieving a tight connection with the battery poles on the battery 12. In this way, the positive and negative battery poles are stably electrically connected to the two connecting wires 32 to form a complete closed loop. The charging device body 2 can charge the battery 12, ensuring a tight and stable connection between the arc-shaped contact pieces 33 and the battery poles. The precise and orderly mechanical transmission process ensures the reliability and stability of the charging connection and reduces the risk of charging failures caused by poor connection.

[0045] In the third step, the push plate 62 will drive the U-shaped blocking cover 64 to move when moving, so that the U-shaped blocking cover 64 slides at the heat dissipation vent 28, that is, when the battery 12 is charged, the U-shaped blocking cover 64 no longer blocks the heat dissipation vent 28. When the battery 12 is charged, the U-shaped blocking cover 64 moves in the opposite direction and resets, so that the U-shaped blocking cover 64 continues to block the heat dissipation vent 28. The heat dissipation fan 31 is located on one side of the dustproof net 3, which is used to discharge the heat in the charging device body 2 to achieve the heat dissipation effect. The heat dissipation channel is opened in time during the charging process, which effectively reduces the temperature inside the charging device body 2, avoids damage to electronic components caused by overheating, and extends the service life of the equipment. After charging is completed, the heat dissipation vent 28 is blocked in time to prevent dust and debris from entering the interior of the equipment, keeping the interior of the equipment clean and dry, which helps to improve the reliability and stability of the equipment, and is fully automatically opened or closed, without the need for an operator to operate alone, making it more convenient to use.

[0046] The fourth step is to slide the bottom of the T-bar 7 in the slide groove 4 67, and the round bar 68 movably penetrates the T-bar 7 to limit the movement of the T-bar 7 and the two racks 71. The T-bar 7 is fixedly connected to the inner wall of the slide groove 4 67 by the spring 69. When the push block 63 no longer applies force to the contact block 73, the elastic reset effect of the spring 69 is utilized to reset the T-bar 7 and the two racks 71. The arc contact piece 33 is reset by resetting the two racks 71, and the connection with the battery pole can be released, thereby realizing the automatic separation of the arc contact piece 33 from the battery pole after charging is completed, simplifying the operation process, improving work efficiency, and having a reasonable structural design.

[0047] In the fifth step, a frame 8 is fixedly installed on the upper end of the base 1, and a protective shell 81 is fixedly connected to the upper end of each frame 8. Each connecting wire 32 passes through the protective shell 81 respectively. Each protective shell 81 is used to limit the connecting wire 32. While ensuring the normal extension and bending of the connecting wire 32, the two connecting wires 32 are prevented from being entangled with other components, thereby ensuring the neatness and orderliness of the internal wiring of the equipment, improving the overall safety and stability of the equipment, and reducing the possibility of failures caused by line confusion.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
