In the actual structure, the base plate 100 has a plate-like structure, the main shaft 210 is fixed to the side of the handle panel 200, and the handle panel 200 can be hinged to the hinge base 120 via the main shaft 210, so that the handle panel 200 can rotate on the base plate 100, and when the handle panel 200 rotates, the main shaft 210 rotates synchronously, and the main shaft 210 rotates about its own axis in fact, that is, the main shaft 210 can rotate circumferentially, and when the main shaft 210 moves to a certain position, the unlocking mechanism can be driven to perform the unlocking action.
In the unlocking mechanism, the unlocking stress block 400 is adjacent to the unlocking arm 300 in the axial direction of the spindle 210, the unlocking stress block 400 can be regarded as a bump which is arranged on the surface of the spindle 210 and extends along the axial direction, the unlocking stress block 400 rotates synchronously with the spindle 210, namely, the unlocking stress block 400 can be driven to rotate synchronously when the spindle 210 rotates, the unlocking arm 300 consists of an annular component and an arm part which extends radially from the annular component, the unlocking arm 300 is rotatably connected with the spindle 210, so that when the spindle 210 rotates within a certain angle range, the unlocking arm 300 does not rotate together with the spindle 210, and the unlocking arm 300 can be driven to rotate only when the unlocking stress block 400 is in abutting connection with the arm part which protrudes radially on the unlocking arm 300 and the spindle 210 continues to rotate towards the end position, and the unlocking traction cable 500 is pulled.
Specifically, the spindle 210 can rotate from an initial position to an end position (the initial position and the end position are both ends of the travel of the spindle 210), the linkage position is between the initial position and the end position, the travel area of the spindle 210 between the initial position and the linkage position is a neutral gear area, the travel area of the spindle 210 between the linkage position and the end position is an unlocking area, the unlocking arm 300 and the unlocking stress block 400 are separated when the spindle 210 rotates in the neutral gear area, the torque of the spindle 210 cannot be transmitted to the unlocking arm 300, and when the spindle 210 rotates in the unlocking area and towards the end position, the unlocking stress block 400 is abutted against the arm part protruding radially on the unlocking arm 300, so that the spindle 210 can transmit the torque to the unlocking arm 300 through the unlocking stress block 400 to further pull the unlocking traction cable 500, and the unlocking action is realized.
When the door is opened, a hand pushes the hand panel cover to rotate inwards and drives the main shaft 210 to rotate from an initial position to a final position (linkage position), the opening groove 110 is exposed and forms a buckle structure, a hand can extend into the opening groove 110 and buckle the buckle structure, the main shaft 210 rotates in a neutral gear area and does not trigger the unlocking mechanism to execute unlocking action, and only when the main shaft 210 rotates to the linkage position, the unlocking stress block 400 is in contact with the unlocking arm 300 and rotates towards the final position along with the main shaft 210 crossing the linkage position (namely, the main shaft 210 enters the unlocking area), and the unlocking stress block 400 pushes the unlocking arm 300 to rotate and pulls the unlocking traction cable 500 to unlock the door.
It should be noted that, the hidden handle in this embodiment is very convenient to operate, and the unlocking and opening of the vehicle door can be realized only by a single-hand pressing action and an external pulling action, so that the user can press the handle panel 200 with a single hand, and then extend the hand into the open slot 110 (i.e. buckle the buckle structure), so that the vehicle door can be unlocked and pulled open, which is very convenient.
The hidden handle has a simple and ingenious structure, can adopt an electric structure or a full-mechanical structure as required, can be suitable for high-end or economical vehicles, is convenient to operate, can realize an unlocking function and a handle structure when the handle panel 200 is pushed inwards, and can directly realize a door opening effect in one step.
