[0032] 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.

[0033] like Figures 1 to 7 As shown, the rotary electric hidden door handle structure includes: a shell frame 1; a handle frame 2, one end of which is rotatably connected to the shell frame 1, and an unlocking portion 200 is provided at the lower end of the handle frame 2; an unlocking rod 3, which is movably arranged in the shell frame 1 and is connected to the external unlocking pull wire, and the unlocking rod 3 movably abuts against one end of the unlocking portion 200; an actuator 4, which is detachably arranged on one side of the shell frame 1, and a transmission shaft 400 is provided on the actuator 4, and the transmission shaft 400 movably abuts against the other end of the unlocking portion 200.

[0034] The shell frame 1 is installed in the car door, and a handle panel is provided on the handle frame 2, so that the handle panel is flush with the end face of the shell frame 1, thereby achieving a hidden door handle effect. The actuator 4 is a car actuator, which is connected to the shell frame 1 by bolts and is used to control the rotation of the transmission shaft 400, so that the transmission shaft 400 presses against the unlocking part 200, and then makes the other end of the handle frame 2 tilt up and separate from the shell frame 1. The user pulls the handle frame 2 so that the handle frame 2 presses against the unlocking rod 3, thereby driving the unlocking rod 3 to move and pull the unlocking wire to unlock the car door.

[0035] like Figures 2 to 7 As shown, preferably, the first shaft pin 500, the torsion spring 501 and the inertia lock 5 are arranged in the shell skeleton 1, the inertia lock 5 is connected with the shell skeleton 1 through the first shaft pin 500, and the torsion spring 501 is sleeved on the first shaft pin 500, and one end of the first shaft pin 500 extends and is connected with the transmission shaft 400.

[0036] A group of mounting holes are arranged on the shell skeleton 1, and a group of mounting holes are also arranged on the left and right sides of the inertia lock 5, the torsion spring 501 is sleeved on the first shaft pin 500, one end of the first shaft pin 500 is inserted into the mounting holes on one side of the inertia lock 5 and the shell, and the other end of the first shaft pin 500 is inserted into the mounting holes on the other side of the inertia lock 5 and the shell and extends into the transmission shaft 400, thereby supporting the transmission shaft 400.

[0037] As shown in Figures 2 to 7 , further preferably, a through slot 502 is arranged on the end of the inertia lock 5, and a guide column 201 is arranged on the unlocking part 200, and the guide column 201 is clamped with the through slot 502.

[0038] The advantage of this design is that after the user unlocks the door and gets on the vehicle and closes the door, the torsion spring 501 on the inertia lock 5 can reset the rotation of the inertia lock 5 after the transmission shaft 400 is reset and rotated by the execution element 4, at this time, the guide column 201 clamped with the through slot 502 drives the other end of the handle skeleton 2 to reset, thereby realizing the hiding.

[0039] As shown in Figure 2 , Figure 5 and Figure 6 , preferably, a first abutting part 401 is arranged on the transmission shaft 400, a second abutting part 202 is arranged on the unlocking part 200, and the first abutting part 401 and the second abutting part 202 abut movably.

[0040] The first abutting part 401 and the second abutting part 202 are in a cam structure, the transmission shaft 400 is rotated by the execution element 4, and the transmission stroke between the two is increased, so that the handle skeleton 2 is rotated to a corresponding angle state.

[0041] As shown in Figure 2 , Figure 5 and Figure 6 , preferably, a third abutting part 203 is arranged on the unlocking part 200, and a fourth abutting part 300 is arranged on the unlocking rod 3, and the third abutting part 203 and the fourth abutting part 300 abut movably.

[0042] After the third abutting part 203 and the fourth abutting part 300 abut, the unlocking rod 3 can move up and down around the connection between the shell skeleton 1 and the shaft, so that the unlocking rod 3 moves while pulling the pull wire, triggering the door switch, and unlocking the door.

[0043] As shown in Figure 5 and Figure 6 As shown, further preferably, the third abutting portion 203 is provided with a first connecting surface 204 , and the fourth abutting portion 300 is provided with a second connecting surface 301 , and the first connecting surface 204 and the second connecting surface 301 are movably abutted against each other.

[0044] The provision of the first connecting surface 204 and the second connecting surface 301 can better enable the third abutting portion 203 to abut against the fourth abutting portion 300, thereby improving the door unlocking response.

[0045] like Figures 2 to 7 As shown, preferably, the unlocking lever 3 is provided with a first connecting portion 302 , the first connecting portion 302 is movably connected to the shell frame 1 , and a spring 303 is provided at the first connecting portion 302 .

[0046] An assembly hole is provided at the first connecting part 302, and a connecting column is provided at the lower end of the shell frame 1. The connecting column is connected to the assembly hole and is limited by a screw. The spring 303 is sleeved on the connecting pin and one end is connected to the shell frame 1, and the other end is connected to the first connecting part 302. The advantage of this arrangement is that after the unlocking rod 3 unlocks the car door with the lifting and lowering movement of the axis, it can be reset by the spring 303 to unlock the car door next time.

[0047] like Figures 2 to 7 As shown, preferably, the unlocking lever 3 has a second connecting portion 304, and the second connecting portion 304 is connected to the external unlocking wire.

[0048] The second connection portion 304 is provided to connect with the external unlocking rod, so that the door is unlocked after the unlocking rod 3 is actuated.

[0049] like Figures 2 to 7 As shown, preferably, a storage groove 100 and a second axle pin 101 are provided on the shell frame 1, a detachable sealing ring 6 is provided at the periphery of the storage groove 100, a first connecting hole 102 is opened on the storage groove 100, and a second connecting hole 205 is provided on one end of the handle frame 2, and the first connecting hole 102 and the second connecting hole 205 are connected by the second axle pin 101.

[0050] A storage slot 100 is provided on the shell frame 1, and the storage slot 100 is used to place the shell frame 1. A group of first connecting holes 102 are opened in the storage slot 100, and a second connecting hole 205 is provided on the handle frame 2. The first connecting hole 102 is adapted to the second connecting hole 205, and the first connecting hole 102 and the second connecting hole 205 are connected through the second axis pin 101, so that the handle frame 2 can rotate on the shell frame 1 around the second axis pin 101. A storage hole connected to the bottom of the storage slot 100 is opened in the storage slot 100, and the storage hole facilitates the contact between the unlocking part 200 and the unlocking rod 3.

[0051] like Figure 2 and Figure 5 As shown, preferably, a lock core 103 is provided in the housing frame 1 .

[0052] The lock core 103 is screwed to the shell frame 1, and the core opening of the lock core 103 is set in the storage slot 100 and is located away from the second shaft pin 101. The advantage of this setting is that when manually unlocking the car door, it is more convenient to insert the key into the core opening to unlock the car door.

[0053] The working principle of this rotary electric hidden door handle structure is as follows: Figure 3 As shown, after the actuator 4 receives the signal, the actuator 4 starts to rotate around its own axis. Since the transmission shaft 400 is installed and fixed on the axis of the actuator 4, the transmission shaft 400 also rotates around the motor axis. The first abutment part 401 on the transmission shaft 400 abuts against the second abutment part 202, and drives the unlocking part 200 to rotate, so that the handle frame 2 rotates to a preset angle state. At this time, the actuator 4 receives the signal to stop moving. Then the user pulls the handle frame 2 by hand, driving the unlocking rod 3 to move along with the axis. The third abutment part 203 abuts against the fourth abutment part 300 through the first connecting surface 204 through the second connecting surface 301. While the unlocking rod 3 moves with the first connecting part 302, the second connecting part 304 pulls the unlocking wire, triggering the door switch, and the door is unlocked and opened. After releasing the handle frame 2, the handle frame 2 is reset to the position due to the force of the spring 303 and the torsion spring 501 at the inertia lock 5. Figure 3 In the state, after the user gets on the car and closes the door, the actuator 4 receives a signal, the axis of the actuator 4 rotates in the opposite direction, driving the transmission shaft 400 to rotate in the opposite direction and reset, and the handle frame 2 is reset by the force of the torsion spring 501.

[0054] In the event of an emergency collision, the handle frame 2 rotates outward from the vehicle door, and the inertia lock 5 rotates in the opposite direction. Since the handle frame 2 is heavier than the inertia lock 5, the handle frame 2 cannot be opened, ensuring collision safety. In this case, the inertia lock 5 not only provides safety protection but also provides reset force for the handle frame 2. Compared with other inertia locks 5, it is safer and saves component costs.

[0055] If the vehicle loses power and the door handle cannot be electrically adjusted through the actuator 4, the door can be opened manually with the key, as follows: press the front end of the door handle to make the door handle frame 2 rotate in a circular motion around the axis of the second axle pin 101, so that the door handle rotates out, then hold the door handle and continue to rotate it to the maximum stroke. At this time, the core opening of the lock cylinder 103 is exposed, and the key is inserted into the core opening of the lock cylinder 103 to unlock and open the door.

[0056] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0057] In addition, in the present invention, descriptions such as "first," "second," and "one" are for descriptive purposes only and should not be understood to indicate or imply their relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0058] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0059] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
