[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 7 As shown, the present flat-lift electric hidden door handle structure comprises: a shell frame 1, on which a handle frame 100 is movably arranged; a front rotating arm 2, one end of which is rotatably arranged on the shell frame 1, and the other end of the front rotating arm 2 is connected to one end of the handle frame 100; a rear rotating arm 3, which is located behind the front rotating arm 2, one end of the rear rotating arm 3 is rotatably arranged on the shell frame 1, and the other end of the rear rotating arm 3 is connected to the other end of the handle frame 100, and the front rotating arm 2 and the rear rotating arm 3 are connected by a connecting rod 4; when the front rotating arm 2 is pushed and one end of the front rotating arm 2 and one end of the rear rotating arm 3 are rotated around the shell, the handle frame 100 on the shell frame 1 is pushed out in parallel.

[0033] The shell frame 1 is provided with a through groove for moving the handle frame 100, and a sealing ring 104 is clamped on the through groove. The sealing ring 104 plays a sealing role to prevent external debris from entering the gap between the shell frame 1 and the handle frame 100 and causing damage to the internal components. A handle panel is clamped on the handle frame 100. The front rotating arm 2 and the rear rotating arm 3 are both high on both sides and low in the middle, similar to a "concave" structure. The advantage of this design is that after one end is connected to the shell frame 1, the other end can move upward, and then when the external driving part pushes the front rotating arm 2 and makes one end of the front rotating arm 2 and one end of the rear rotating arm 3 rotate around the shell, the other end of the front rotating arm 2 and the other end of the rear rotating arm 3 can push the handle frame 100 located in the shell frame 1 outward through the through groove along a certain flatness.

[0034] like Figure 2 、 Figure 5 and Figure 6 As shown, preferably, an execution assembly 5 is provided in the shell frame 1 , and a driving end of the execution assembly 5 is movably abutted against the front rotating arm 2 .

[0035] The execution assembly 5 consists of an actuator and a guard plate. The guard plate is used to protect the actuator. The actuator is connected to the guard plate and the shell frame 1 through screws. After the door handle receives the signal from the body control module BCM, the shaft head of the actuator, which is the driving end, starts to move linearly along the axial direction, so that the handle frame 100 in the shell frame 1 is pushed out.

[0036] like Figure 2 、 Figure 5 and Figure 6 As shown, further preferably, the driving end of the execution assembly 5 is connected to a push block 6, the push block 6 is slidably set on the shell frame 1, the front rotating arm 2 has an inclined portion 203, and the push block 6 movably abuts against the inclined portion 203.

[0037] The shell frame 1 is provided with a slide groove, and the push block 6 can move on the slide groove. The push block 6 is provided with a card slot. The shaft head of the actuator, that is, the driving end, is connected with the push block 6 through the card slot. Because the front end of the front rotating arm 2 is provided with an inclined portion 203, the inclined portion 203 has a slope surface. When the shaft head, that is, the driving end of the actuator moves, it drives the push block 6 to move in the direction of the front rotating arm 2. The push block 6 and the slope surface press against each other, and the front rotating arm 2 is subjected to the force given by the push block 6, so that one end of the front rotating arm 2 and one end of the rear rotating arm 3 rotate around the shell, and the front rotating arm 2 and the rear rotating arm 3 rotate around the shell. The arms 3 are connected by a connecting rod 4, the other end of the front rotating arm 2 is connected to one end of the handle frame 100, and the other end of the rear rotating arm 3 is connected to the other end of the handle frame 100, forming a parallelogram motion mechanism. The other end of the front rotating arm 2 and the other end of the rear rotating arm 3 can push the handle frame 100 located in the shell frame 1 outward through the through groove along a certain flatness. In this structure, the front and rear rotating arms 3 rotate at the same angular velocity, the thrust is consistent, the dynamic balance is better, and it can increase higher loads. When the car door is covered with ice in winter, it has better ice-breaking ability.

[0038] like Figures 2 to 6 As shown, one end of the front rotating arm 2 has a forward rotating first axis pin 200, which is connected to the shell frame 1, and the other end of the front rotating arm 2 has a forward rotating second axis pin 201. One end of the handle frame 100 is provided with a first connecting part 101, and the forward rotating second axis pin 201 is connected to the first connecting part 101.

[0039] The front rotating arm 2 is rotationally connected to the shell frame 1 through the forward rotating first axle pin 200, and the front rotating arm 2 is connected to the first connecting part 101 located at the lower end of the handle frame 100 through the forward rotating second axle pin 201. When the push block 6 pushes the front rotating arm 2, the first connecting part 101 will be pushed up. It is worth mentioning that the left side of the first connecting part 101 is inclined. The advantage of this setting is that it is convenient for the hand frame to move parallel to the left slightly through the through slot when one end of the front rotating arm 2 and one end of the rear rotating arm 3 rotate around the shell.

[0040] like Figures 2 to 6 As shown, one end of the rear rotating arm 3 has a rear rotating first axis pin 300, which is connected to the shell frame 1, and the other end of the rear rotating arm 3 has a rear rotating second axis pin 301. The other end of the handle frame 100 is provided with a second connecting part 102, and the rear rotating second axis pin 301 is connected to the second connecting part 102.

[0041] The rear rotating arm 3 is rotatably connected with the shell frame 1 through a rear rotating first shaft pin 300, and the rear rotating arm 3 is connected with the second connecting part 102 at the lower end of the handle frame 100 through a rear rotating second shaft pin 301, that is, the first connecting part 101 and the second connecting part 102 are respectively located at the two lower ends of the handle frame 100, and then when the push block 6 pushes the front rotating arm 2, the second connecting part 102 is lifted due to the connection between the front rotating arm 2 and the rear rotating arm 3 through the connecting rod 4.

[0042] As shown in Figures 2 to 6 , the front rotating first shaft pin 200 and the rear rotating first shaft pin 300 are both provided with a torsion spring 7.

[0043] The front rotating first shaft pin 200 and the rear rotating first shaft pin 300 are both provided with a torsion spring 7, and the advantages of this arrangement are that when the car door is closed, the actuator receives a signal, the shaft head of the actuator, that is, the driving end, reversely acts, the parallelogram mechanism is subjected to the force of the torsion spring 7 on the front rotating first shaft pin 200 and the torsion spring 7 on the rotating first shaft pin, so that the door handle is reset.

[0044] As shown in Figures 2 to 6 , the front rotating arm 2 is provided with a front rotating third shaft pin 202, the front rotating third shaft pin 202 is located beside the front rotating first shaft pin 200, the rear rotating arm 3 is provided with a rear rotating third shaft pin 302, the rear rotating third shaft pin 302 is located beside the rear rotating first shaft pin 300, the front end of the connecting rod 4 is connected with the front rotating third shaft pin 202, and the rear end of the connecting rod 4 is connected with the rear rotating third shaft pin 302.

[0045] As shown in Figure 2 and Figure 5 , the front end of the connecting rod 4 is connected with the front rotating third shaft pin 202, and the rear end of the connecting rod 4 is connected with the rear rotating third shaft pin 302, so that when the front rotating arm 2 rotates, the rear rotating arm 3 also rotates.

[0046] The rear end of the connecting rod 4 is provided with a first waist-shaped hole 400, the second connecting part 102 is provided with a second waist-shaped hole 103, the rear rotating third shaft pin 302 is slidingly arranged in the first waist-shaped hole 400, and the rear rotating second shaft pin 301 is slidingly arranged on the second waist-shaped hole 103.

[0047] The first waist-shaped hole 400 on the rear end of the connecting rod 4 is in a slightly inclined state, and the first waist-shaped hole 400 and the second waist-shaped hole 103 are arranged to facilitate the user to pull the door handle, so that the control module BCM receives a signal to unlock the door, and the door is opened.

[0048] As shown in Figures 2 to 6 , the shell frame 1 is rotatably provided with an unlocking block 8, and the rear rotating arm 3 movably abuts against the unlocking block 8.

[0049] An unlocking pin is provided on the unlocking block 8, which is rotatably connected to the shell frame 1, and a torsion spring 7 is also provided on the unlocking pin. The unlocking block 8 is movably connected to the control module BCM. When the unlocking block 8 is rotated to a certain position, the control module BCM receives a signal to unlock the door, so that the door is opened. It is worth mentioning that an inertia lock 10 is also provided in the shell frame 1, and the inertia lock 10 is also correspondingly provided with an inertia pin. The inertia pin is connected to the shell frame 1. The inertia lock 10 is provided to prevent the inertia lock 10 from swinging to prevent the door from being opened when the car brakes suddenly during driving, thereby protecting the passengers in the car.

[0050] like Figure 2 As shown, a lock core component 9 is provided on the housing frame 1 .

[0051] The lock core component 9 has a lock core and a lock core crank. The lock core is installed on the shell frame 1. The lock core crank is clamped on the shell frame 1 and cooperates with the lock core. The lock core component 9 is set to prevent the vehicle from losing power. When the door cannot be opened by the actuator, manual operation can be used to insert the key into the lock core component 9 to open the door.

[0052] The working principle of this horizontal lifting electric hidden door handle structure is: after the door handle receives the signal from the body control module BCM, after the actuator receives the signal, the shaft head of the actuator, that is, the driving end, starts to move linearly along the axial direction. Because the push block 6 is engaged with the shaft head of the actuator, and the push block 6 slides in the slide groove of the shell frame 1, the shaft head of the actuator extends, thereby driving the push block 6 to press against the inclined part 203 of the front rotating arm 2, and the push block 6 moves forward. The front rotating arm 2 is subjected to the force given by the push block 6 and rotates around the axis of the first forward rotating shaft pin 200. The front rotating arm 2 and the rear rotating arm 3 are connected by the connecting rod 4 to achieve rotation at the same angle. The other end of the front rotating arm 2 is connected to one end of the handle frame 100, and the other end of the rear rotating arm 3 is connected to the other end of the handle frame 100, thereby realizing a parallelogram motion mechanism. The handle frame 100 located in the shell frame 1 rises and is pushed out in parallel along a certain flatness.

[0053] like Figure 4 As shown, after the door handle pops out, a person puts his hand into the door handle and pulls the door handle. At this time, the door handle rotates around the axis of the front rotating arm 2, and the rear rotating arm 3 rotates passively. The connecting rod 4 is provided with a first waist-shaped hole 400, and the rear rotating third axis pin 302 on the rear rotating arm 3 slides along the first waist-shaped hole 400 to prevent the mechanism from getting stuck. The handle frame 100 is provided with a second waist-shaped hole 103, and the rear rotating second axis pin 301 on the rear rotating arm 3 slides along the second waist-shaped hole 103 to prevent the mechanism from getting stuck. During the rotation of the rear rotating arm 3, the unlocking block 8 will be pulled to rotate, and the BCM receives a signal to unlock the car door and open it. After releasing the door handle, the door handle is reset to the position due to the force of the torsion spring 7 on the rear rotating first axis pin 300. Figure 3State, close the door, the actuator receives the signal, the actuator reverses, the shaft head resets, the parallelogram mechanism is affected by the torsion spring 7 on the front rotating first shaft pin 200 and the torsion spring 7 on the rear rotating first shaft pin 300, the door handle moves to reset to Figure 1 State.

[0054] As Figure 7 shown, if the vehicle is powered off, the door handle cannot be adjusted by the actuator, and the door can be opened by manual operation with a key. Specifically, the front end of the door handle is pressed to make the door handle rotate around the axis of the front rotating first shaft pin, and the rear end of the door handle is raised; the door handle is buckled to continue moving until it is fully extended, the key is inserted from the middle position of the handle, and the door is opened by unlocking the key.

[0055] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.
