Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging ports, and in particular to an actuator for an automobile door handle. Background Art

[0002] The actuator is an indispensable and important component in the automatic control system. Its function is to receive the control signal sent by the controller, change the size of the controlled medium, and thus maintain the controlled variable at the required value or within a certain range. Actuators can be divided into three categories according to their energy form: pneumatic, hydraulic, and electric. Pneumatic actuators use compressed air as energy. They are characterized by simple structure, reliable and stable operation, large output thrust, convenient maintenance, fireproof and explosion-proof, and low price. Therefore, they are widely used in chemical, papermaking, oil refining and other production processes. They can be easily used with passive instruments. Even when using electric instruments or computer control, pneumatic actuators can still be used as long as the electrical signal is converted into a standard air pressure signal of 20-100kPa through an electric-to-gas converter or an electric-to-gas valve positioner. Electric actuators have convenient energy access and rapid signal transmission, but they have complex structures and poor explosion-proof performance. Hydraulic actuators are basically not used in chemical, oil refining and other production processes. They are characterized by large output thrust;

[0003] With respect to the above-mentioned related technologies, the inventor believes that since the actuator of the existing automobile door handle adopts an electric actuator with relatively small torque, the automobile door may not be completely closed when closed and the cover may be opened and closed slowly, thereby affecting the charging efficiency and speed, and causing the user to wait for too long for charging. In addition, the cover is not closed tightly, and the gap generated may cause the cover to open wider or open due to external wind pressure when the vehicle is driving at high speed, exposing the charging port to the outside, affecting the sealing of charging, etc. In addition, since there is a micro switch in the design to control the opening angle of the automobile door, if the micro switch fails or is damaged, the automobile door may not be opened or closed normally, thereby affecting the safety and reliability during charging.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In order to solve the problem that the existing actuator has a small torque and requires an external micro switch to control the opening angle, which affects the charging efficiency and the safety and reliability during the charging process, the present invention provides an actuator for a car door handle.

[0006] The present application provides an actuator for a car door handle that adopts the following technical solution:

[0007] An actuator for a car door handle comprises a shell, a top cover is welded on the top of the shell, a driving plate is fixedly connected to the inner cavity side wall of the shell by bolts, a PCB is fixedly connected to the surface of the driving plate, a plurality of groups of electronic components are fixedly connected to the top and bottom of the driving plate, a plurality of groups of wiring harness fixing points are arranged inside the PCB, a clutch gear mechanism is arranged inside the shell, and the clutch gear mechanism is arranged at the bottom of the PCB and the driving plate.

[0008] Preferably, one end of several groups of wiring harness fixing points is fixedly connected to a wiring harness assembly, one end of the wiring harness assembly away from the wiring harness fixing point is fixedly connected to a wiring harness connector, and a protective hose is movably sleeved on the surface of the wiring harness assembly.

[0009] Preferably, the clutch gear mechanism includes a drive motor, and the bottom of the drive motor is fixedly connected to the inner cavity side wall of the shell by bolts.

[0010] Preferably, two groups of motor pins are fixedly connected to the top of the driving motor, and the tops of the two groups of motor pins are fixedly passed through the PCB board.

[0011] Preferably, a potentiometer is provided inside the driving board, and the potentiometer is fixedly connected to the bottom of the PCB board.

[0012] Preferably, a control system is included, and the control system includes a cover switch module, a Bluetooth module, a breathing light module and a communication module.

[0013] Preferably, the cover switch module can control the opening, closing, and anti-pinch functions of the charging port and has an ice-breaking function.

[0014] Preferably, the actuator in the Bluetooth module is the host and the charging gun is the slave, and the charging gun is triggered by the charging gun, and the charging gun (with Bluetooth) approaches and moves away from the charging port cover to realize automatic opening and closing of the charging port cover.

[0015] In summary, the present invention has the following beneficial technical effects:

[0016] 1. By using the control system and other related components in coordination, a drive motor with a large torque output is used, and the clutch gear mechanism is provided therewith. By increasing the gear reduction ratio, the output torque can be significantly increased, and sufficient power supply can be provided to ensure that the drive motor can obtain sufficient current and power to generate a larger torque output. Compared with the prior art, an actuator with sufficiently large torque can open and close the car door more quickly, thereby improving the charging efficiency. During the charging process, the charging port can be quickly and accurately plugged in and out, reducing waiting time and improving user experience. At the same time, it can ensure that the car door is completely closed when closed to prevent safety hazards such as current leakage and electric shock during charging. Including in severe weather conditions, such as low temperature, ice and snow, the car door can still be opened and closed normally, providing better convenience of use. Actuators with large torque usually have a longer service life and durability, can better withstand the test of long-term use and multiple opening and closing operations, reduce the frequency of failures and repairs, and improve the reliability of the charging port assembly. At the same time, it can also better adapt to charging equipment of different brands and types, and provide a wider range of compatibility.

[0017] 2. Through the coordinated use of the control system and other related components, a closed-loop control system is established. The movement of the actuator is adjusted in real time through the feedback signal, and the opening angle of the actuator can be monitored in real time. Through the control program, the movement of the actuator can be adjusted according to the set target angle to achieve the specified opening angle. At the same time, the control system can receive instructions sent by the control program, and adjust the speed and direction of the drive motor according to the instructions, thereby controlling the opening angle. Compared with the existing technology, by using a program to control the opening angle, it is no longer dependent on an external micro switch, which can reduce the possibility of mechanical component failure, improve the reliability of the actuator, reduce the use of parts and the complexity of the assembly process, reduce costs and manufacturing risks, and can adapt to the requirements of different application scenarios, providing more choices and flexibility.

The tops of the two groups of motor pins 10 are fixedly passed through the PCB board 13. A potentiometer 9 is provided inside the driving board 6, and the potentiometer 9 is fixedly connected to the bottom of the PCB board 13.

[0026] By adopting the above technical solution, the outer shell 1 and the top cover 2 are laser welded to make the actuator have good sealing performance as a whole. The overall size of the actuator is 30.5 mm x 65 mm x 95 mm, the sealing level is IP67, it has high dustproof and waterproof performance, and the maximum noise is 40dB@500mm. The voltage range of the actuator is 9-16 volts. The voltage of the actuator is 13.5 volts, the current is 0.18 amperes, and the stall current is 0.85 amperes when the actuator is in normal operation. The temperature range of the actuator in normal use is -30°C to 80°C. There is a clutch gear mechanism 12 inside the outer shell 1. When the output end is abused and the force exceeds the clutch force of the clutch gear mechanism 12, the clutch is disengaged to protect the clutch gear mechanism 12 inside the outer shell 1 from damage. At the same time, the drive plate 6 is arranged in the outer shell 1, and there is grease inside, and the drive plate 6 has neutral grease, which has good Good anti-static performance can ensure the normal operation of several groups of electronic components 8 provided on the top and bottom thereof, and the PCB board is made of insulating materials such as pulp and resin mixture, and is covered with a layer of conductive material to form a circuit path, which is convenient for fixing the motor pin 10 and the potentiometer 9. The motor pin 10 is used as a connector of the drive motor 11, which is used to connect the drive motor 11 with the power supply and control circuit, and as an interface for providing power supply and signal transmission, so that the drive motor 11 can work normally. By connecting the motor pin 10, power can be supplied to the drive motor 11, and the speed, direction and stop of the drive motor 11 can be controlled. The potentiometer 9 is an adjustable resistor The potentiometer is used to adjust the voltage or current in the circuit. It consists of a fixed resistor and a slidable connector. By adjusting the position of the sliding connector, the voltage at both ends of the potentiometer can be changed, thereby adjusting the current or voltage value in the circuit. The effective linearity range of the potentiometer 9 is ±160°. Within this range, the linear tolerance of the output electrical signal (voltage ratio, or resistance) corresponding to each angle is ±2%. For example, the power supply of the potentiometer is +5V, and at the 0° position, it is 50% of the input voltage, that is, 2.5V. The voltage tolerance range is 2.48V~2.52V, corresponding to the angle error of ±2.65°, that is, the potentiometer 9 is arranged at the last level of the output, and the movement is synchronized with the mouth cover. The angle of the mouth cover movement is It can correspond to the rotation angle of the potentiometer 9, and its wiring harness assembly 3 includes multiple groups of light control lines, which can be used to protect the multiple groups of light control lines through the protective hose 4, and can be used to connect the corresponding control switch system through the provided wiring harness connector 5, and the light control line can be divided into a positive power connection line, a circuit grounding line, a signal connection line and a clock input line. The positive power connection line can be used to connect the positive power of the actuator with the positive power of the power supply, and provide power supply to the circuit and function of the actuator, which ensures that the actuator can work normally and receive the required power, and the circuit grounding line is used to connect the circuit grounding terminal of the actuator with the grounding terminal of the power supply to establish a complete grounding loop in the circuit.It helps to provide circuit stability, reduce interference, and ensure the safe operation of the circuit. The signal connection line is used to transmit signals, and transmits control signals from the control system or other equipment to the actuator to achieve control of the lights. Through different signal transmission methods, such as voltage changes or digital signals, different lighting adjustments, switches and other functions can be achieved. The final clock input line is used to synchronize the operation of the actuator, especially in scenarios that require time synchronization. The clock input line inputs an external clock signal into the actuator to ensure that the actuator performs the corresponding tasks or operations according to a unified time standard. The wiring harness fixing point 7 also includes a positive input power line, a spare wiring harness, a negative input power line, a high-level signal line, a low-level signal line, a switch power line and a power ground line. Its positive input power line can be used to connect the positive input terminal of the actuator with the positive pole of the power supply to provide working power for the actuator. The backup wiring harness is usually prepared to deal with some special situations. For example, when the positive input power line or the negative input power line fails, you can switch to the backup wiring harness to keep the normal operation of the actuator. The negative input power line can be used to connect the negative input terminal of the actuator with the negative pole of the power supply, and together with the positive input power line, provide a complete power supply circuit for the actuator. The high-level signal line is used to receive the input of high-level signals, usually used to control certain functions or states of the actuator. When the high-level signal is input, the actuator can perform corresponding actions or operations, and the low-level signal line is used to receive the input of low-level signals, similar to the high-level signal line. When a low-level signal is input, the actuator can perform corresponding actions or operations, usually corresponding to the high-level signal line, to achieve different control logics. The switching power line is used to connect the switching power supply of the actuator to control the switching state of the actuator. By controlling the connection and disconnection of the switching power line, the actuator can be started or stopped. Finally, the power ground line can be used to connect the actuator to the ground terminal of the power supply to ensure the safety and stability of the circuit.

Each time the CPCM is driven, the motor is driven at 100% of the maximum voltage PWM; 2. If there is any CPCM shutdown request during the three ice-breaking periods, the ice-breaking mode will be exited; 3. The ice-breaking mode will be exited if there is any CPCM shutdown request during the three ice-breaking periods; 4. The ice-breaking mode will be activated only once in a single ignition cycle (non-OFF gear returns to OFF gear as the starting point of an ignition cycle), and the CPCM expansion failure will be counted. The count value will increase by 1 after each failure. The CPCM loses power or the CPCM manual expansion function is successfully executed, and the count value returns to zero.
