Description

Technical Field

[0001] The utility model belongs to the technical field of charging doors, and in particular relates to a push-to-open automatic-opening automobile charging door mechanism. Background Art

[0002] With the increasing popularity of new energy vehicles in China and the rapid growth of the new energy market, OEMs are increasingly pursuing low-cost, lightweight, and simplified charging doors for newly developed models. Currently, the mainstream charging doors on the market are electric and manual. Electric charging doors incorporate a motor, actuator, button, and mechanical assembly, resulting in a complex structure, high cost, and a weight disadvantage. Manual push-type charging doors are available in semi-automatic and automatic pop-up styles. Mainstream manual push-type charging doors have the following disadvantages: 1. The vehicle's in-cabin computer system cannot communicate with the charging door, making it unable to detect whether the charging door is open or closed; 2. The vehicle's battery charge status, such as whether it is waiting to charge, charging, or fully charged, cannot be intuitively detected from outside the vehicle; 3. Manually opening the charging door requires first manually pressing the unlock button and then manually tilting the door panel to a certain angle for it to automatically open; 4. The door panel can open quickly and unevenly, resulting in a poor user experience. Utility Model Content

The strip is located on the side of the limiting boss 101 away from the base 2, and the strip 102 is arranged parallel to the limiting boss 101.

[0043] The process from closing to opening of door panel 1: Figure 8 and Figure 9 As shown, at this time, the door panel 1 is in a closed state, the two ends of one side of the lock head 91 of the rotary rebounder 9 are in contact with the limiting boss 101, and the other side is in contact with the pressure strip 102. The lock head 91 and the pressure strip 102 are vertically arranged and are in a compressed locked state. When the door panel 1 is pressed, the force is transmitted to the pressure strip 102 through the door panel 1. The pressure strip 102 squeezes the lock head 91 on the rotary rebounder 9 of the base 2. After being squeezed, the lock head 91 rotates 90 degrees. The lock head 91 and the pressure strip 102 are changed from being vertically arranged to being parallel, and at the same time extend outward toward the door panel 1. The lock head 91 is no longer limited by the limiting boss 101, and is separated from the limiting boss 101 and is in an extended unlocked state. The door panel 1 is released by the rotary rebounder 9, and the torsion spring 4 is Figure 3 and Figure 4 The fully compressed posture releases part of the elastic potential energy, which is converted into torque to drive the gear pin 3 to rotate clockwise, driving the gooseneck arm 121 to rotate clockwise, and the door panel 1 is linked with the gooseneck arm 121 until it reaches the open position of the door panel 1 and stops. The door panel 1 can automatically pop open without manual manipulation. Figure 5 and Figure 6 at this time, the protrusion 33 of the gear pin 3 and the metal spring 61 of the micro switch 6 change from contact to separation, and the metal spring 61 returns to a free state, triggering the resistance change of the micro switch 6. The car receives the resistance change of the micro switch 6 through the connector 8, thereby recognizing that the door panel 1 has changed to the open state.

[0044] The process from opening to closing of the door panel 1: When the door panel 1 is pressed, the gooseneck arm 121 rotates counterclockwise, and the gear pin 3 rotates counterclockwise under the drive of the gooseneck arm 121. The torsion spring 4 rotates counterclockwise and is compressed under the counterclockwise torque of the gear pin 3 until the torsion spring 4 is in a fully compressed state. Figure 10As shown, the door panel 1 drives the pressure strip 102 to squeeze the lock head 91 of the rotary rebounder 9 of the base 2, and the lock head 91 changes from an extended state to a compressed state. At the same time, the lock head 91 and the pressure strip 102 change from a parallel setting to a vertical setting. The two ends of one side of the lock head 91 of the rotary rebounder 9 contact the limiting boss 101, and the other side contacts the pressure strip 102, which is in a locked state, and the door panel 1 is in a closed position. At this time, the protrusion 33 of the gear pin 3 and the metal spring 61 of the micro switch 6 change from separation to contact, and compress the metal spring 61 of the micro switch 6. After the metal spring 61 is compressed, the resistance change of the micro switch 6 is triggered. The car will receive the blocking change of the micro switch 6 through the connector 8, thereby recognizing that the door panel 1 has changed to a closed state.

[0045] Working of the charging indicator light 7: When the car battery is charging, the car will transmit the battery charging status (waiting for charging / charging / charging completed / charging fault / scheduled charging) to the charging indicator light 7 on the base 2 through the Lin line of the connector 8. After receiving the Lin signal, the charging indicator light 7 will display the charging status of the car battery simply and effectively through different states (flashing 2S / breathing / long on / off / flashing 4S).

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
