[0021] See also Figures 1 to 4 ,in, Figure 1 This is a locked position diagram of the hidden electric door handle of a car according to the first embodiment of the utility model. Figure 2 This is a pre-opening position diagram of the hidden automobile electric door handle of the first embodiment of the utility model. Figure 3 This is a diagram of the maximum opening position of the hidden automobile electric door handle of the first embodiment of the utility model. Figure 4 This is an accessory diagram of the switch assembly of the first embodiment of the utility model. The utility model provides a hidden automobile electric door handle, including a base 101, a transmission assembly and a switch assembly. The transmission assembly includes a push motor 102, a push rod 103, a first swing arm 104, a second swing arm 105, a connecting rod 106, a pin 107 and a lever 108. The switch assembly includes a handle body 109, a handle cover 110, a button switch 111, a clip 112 and a button sensor 113. The above-mentioned solution solves the problem that the traditional door handle has large wind resistance and the handle is exposed and easy to bump. The structure is simple, the installation is convenient, safe and reliable, and the competitiveness of the car is improved.

[0022] According to this specific embodiment, the push motor 102 is fixedly connected to the base 101 and is located inside the base 101. The push rod 103 is connected to the push motor 102 and is located inside the base 101. There are multiple pins 107. The first swing arm 104 is rotatably connected to the inside of the base 101 through the pin 107. The second swing arm 105 is rotatably connected to the inside of the base 101 through the pin 107. The connecting rod 106 is rotatably connected to the second swing arm 105 and is located at the top of the second swing arm 105. The switch assembly is connected to the first swing arm 104. The swing arm 104 is connected to the connecting rod 106, the connecting assembly is connected to the base 101, the base 101 is connected to the body sheet metal, and provides support for the electric door handle of the car. The push motor 102 provides power for the mechanism. Before unlocking the car, the push motor 102 controls the push rod 103 to be in the original position, so that the first swing arm 104 and the second swing arm 105 and the connecting rod 106 are maintained at the initial position of the base 101), so that the handle is in a locked state. When the car is unlocked, the ECU energizes the push motor 102 to control the push rod 103. 03 pushes the No. 1 swing arm 104 to rotate along the pin shaft 107, and at the same time, the No. 2 swing arm 105 and the connecting rod 106 are pushed to rotate along the pin shaft 107 through the push rod 103, and the handle body 109 is rotated and pushed out along the connecting axis. When the push rod 103 moves forward, click to start the Hall counting to limit the forward stroke of the push rod 103. After the movement is in place, the feedback signal is sent to the ECU, and the ECU controls the push motor 102 to stop driving, and the push rod 103 stops moving. At the same time, this structure has a push rod 103 limit structure to prevent motor failure. The push rod 103 continues to move, and the connecting rod 106 system The movement relationship of the system drives the handle half assembly to move, and the handle body 109 is pushed out from the inside of the base 101, so that the car electric door handle is in a pre-opening state. When opening the car door, the handle body 109 is pulled to rotate along the connecting axis. At the same time, the lever 108 is rotated until the maximum opening position. The lever 108 drives the pull wire or the push rod to drive the lock block to unlock, thereby achieving the purpose of controlling the car door lock; when the lever 108 does not reach the maximum position, it touches the micro switch set in the base, and the car lock is electronically unlocked. This function is applicable to the electronic lock block.

[0023] Among them, one end of the lever 108 is rotatably connected to the base 101 through the pin shaft 107, and is located at the tail end of the No. 2 swing arm 105. One end of the lever 108 and the No. 2 swing arm 105 are transmitted through a connecting rod, and the other end of the lever 108 is connected to a pull wire. By pulling the handle body 109, the No. 2 swing arm 105 is rotated, and the control of the car door handle lock body is achieved through the transmission between the No. 2 swing arm 105 and the lever 108.

[0024] Secondly, one end of the handle body 109 is rotatably connected to the No. 1 swing arm 104, and the other end of the handle body 109 is rotatably connected to the connecting rod 106. The handle body 109 is located on the outside of the base 101. The handle cover 110 is fixedly connected to the handle body 109 and is located on the outside of the handle body 109. The button switch 111 is detachably connected to the handle cover 110 and is located between the handle cover 110 and the handle body 109. The handle body 109 provides support and limiting functions for the switch assembly, and the handle cover 110 provides sealing for the handle body 109 and the base 101. The button switch 111 is used to transmit electrical signals to the ECU system in the car.

[0025] Again, the clip 112 is fixedly connected to the button switch 111 and is located between the button switch 111 and the handle body 109. The button sensor 113 is detachably connected to the clip 112 and is located between the clip 112 and the handle body 109. The clip 112 is used to limit the button sensor 113. When the car is unlocked from the outside, the button switch 111 is pressed so that the button sensor 113 transmits an electrical signal to the ECU system in the car. The ECU system controls the push motor 102 so that the push motor 102 drives the transmission assembly to push the switch assembly out of the base 101.

[0026] A hidden electric door handle for a car is used in the embodiment. The base 101 is connected to the car body sheet metal to provide support for the electric door handle for the car. The push motor 102 provides power for the mechanism. Before unlocking the car, the push motor 102 controls the push rod 103 to be in the original position, so that the first swing arm 104, the second swing arm 105 and the connecting rod 106 are maintained at the initial position of the base 101), so that the handle is in a locked state. When the car is unlocked, the ECU energizes the push motor 102 to control the push rod 103, and pushes the first swing arm 104 to rotate along the pin shaft 107 through the push rod 103. At the same time, the second swing arm 105 and the connecting rod 106 are pushed along the pin shaft 107 through the push rod 103 to rotate, and the handle body 109 is rotated and pushed out along the connecting shaft. When the push rod 103 moves forward, click to start the Hall counting to limit the forward stroke of the push rod 103. After the movement is in place, a signal is fed back to the ECU. ECU controls the push motor 102 to stop driving, and the push rod 103 stops moving. At the same time, this structure is provided with a push rod 103 limit structure to prevent the motor from failing. The push rod 103 continues to move, and the movement relationship of the connecting rod 106 system drives the handle semi-assembly to move, and the handle body 109 is pushed out from the inside of the base 101, so that the electric door handle of the automobile is in a pre-opening state. When opening the door of the automobile, the handle body 109 is pulled to rotate along the connecting shaft. At the same time, the lever 108 is rotated until the maximum opening position, and the lever 108 drives the pull wire or the push rod to drive the lock block to unlock, thereby achieving the purpose of controlling the automobile door lock; when the lever 108 does not reach the maximum position, it touches the micro switch set in the base, and the car lock is electronically unlocked. This function is applicable to the electronic lock block, which solves the problem that the traditional door handle has large wind resistance and the handle is exposed and easy to bump. It has a simple structure, is easy to install, is safe and reliable, and improves the competitiveness of the automobile.
