[0039] Example 1

[0040] like Figures 1-3 As shown, in this embodiment, the concealed door handle actuator includes a housing 1, a drive component 2, and a transmission assembly. The drive component 2 is disposed within the housing 1. The transmission assembly includes a transmission mechanism 3, a first gear 4, a sleeve 5, and a rotating component 6. The transmission mechanism 3 is disposed within the housing 1 and is connected to the output end of the drive component 2. The rotating component 6 is rotatably disposed within the housing 1. The sleeve 5 is fitted onto the rotating component 6. The first gear 4 is fitted onto the sleeve 5. Both the outer ring of the sleeve 5 and the inner ring of the first gear 4 are provided with knurled structures 7. The first gear 4 and the sleeve 5 are fixed together by the knurled structures 7. The first gear 4 is also connected to the transmission mechanism 3, and the sleeve 5 is connected to the rotating component 6, enabling the rotating component 6 to move linearly along its own axis.

[0041] The housing 1 is assembled from an upper shell and a lower shell to form a receiving cavity. The drive component 2 and the transmission assembly are both located within the receiving cavity of the housing 1. The drive component 2 is a motor, which can be connected to the connection port via a terminal wire to provide power. The sleeve 5 is a nut, and the rotating component 6 is a lead screw. The transmission mechanism 3 is located between the output end of the drive component 2 and the rotating component 6. The transmission mechanism 3 consists of a worm gear and a helical gear. The drive component 2 is connected to the first gear 4 through the transmission mechanism 3, which can provide a large transmission ratio and torque in the transmission path, thereby ensuring smooth transmission of the actuator under heavy loads. The rotating part 6 is rotatably disposed inside the housing 1, and the sleeve 5 is sleeved on the rotating part 6. The inner ring of the sleeve 5 and the outer ring of the rotating part 6 are engaged by threaded transmission. The inner ring of the first gear 4 is provided with a knurled structure 7, and the corresponding position of the outer ring of the sleeve 5 is provided with a knurled structure 7. The sleeve 5 and the first gear 4 are engaged by their respective knurled structures 7, so that the first gear 4 is fixed to the sleeve 5, which plays the role of preventing rotation and preventing disengagement, and avoids the first gear 4 slipping on the sleeve 5 and affecting the transmission.

[0042] The working process of the concealed door handle actuator is as follows: the drive component 2 is activated. Under the driving action of the drive component 2, the power of the drive component 2 is transmitted to the first gear 4 through the transmission mechanism 3. The first gear 4 drives the sleeve 5 to rotate synchronously relative to the housing 1. The rotating component 6 is in transmission cooperation with the sleeve 5. Under the rotation drive of the sleeve 5, the rotating component 6 can move forward or backward in a straight line relative to the sleeve 5 along its own axis. When the rotating component 6 moves forward outward and touches the outer micro switch, it stops at the limit. Or when the rotating component 6 moves backward inward and touches the inner micro switch, it stops at the limit. The circular motion of the drive component 2 is converted into the linear reciprocating motion of the rotating component 6, thereby achieving the effect of retractable concealed door handle.

[0043] Reference Figure 3 The knurled structure 7 includes multiple protrusions spaced apart. The outer ring of the sleeve 5 has multiple protrusions spaced apart along the circumference of the sleeve 5, and the inner ring of the first gear 4 has multiple protrusions spaced apart along the circumference of the first gear 4. The first gear 4 is sleeved on the sleeve 5, and the multiple protrusions of the first gear 4 can be interlocked and fixed with the grooves between every two adjacent protrusions on the sleeve 5, so that the first gear 4 is fixed to the sleeve 5, which plays a role in preventing rotation and disengagement, and avoids the first gear 4 slipping on the sleeve 5 and affecting the transmission.

[0044] Reference Figure 2The concealed door handle actuator also includes a first worm gear 8, which is fixedly connected to the output end of the drive unit 2 and is connected to the transmission mechanism 3. The transmission mechanism 3 includes a second gear 31 and a second worm gear 32. The second gear 31 is rotatably mounted on the housing 1 and is connected to the first worm gear 8. The second gear 31 is fixedly mounted on a connecting shaft 9, and the second worm gear 32 is fixedly sleeved on the connecting shaft 9 and is connected to the first gear 4. The drive unit 2, connected to an external power source, provides power. The drive unit 2 rotates and drives the first worm gear 8 on the output end to rotate coaxially. The first worm gear 8 drives the second gear 31, which is meshed with the first worm gear 8, to rotate. The second worm gear 32 and the second gear 31 rotate coaxially through the connecting shaft 9. The second worm gear 32 drives the first gear 4, which is meshed with it, to rotate. The first gear 4 drives the sleeve 5 to rotate synchronously relative to the housing 1. The rotating part 6 is connected to the sleeve 5. Under the rotation drive of the sleeve 5, the rotating part 6 can move forward or backward in a straight line relative to the sleeve 5 along its own axis.

[0045] Preferably, the first gear 4 and the second gear 31 are configured as helical gears. The first gear 4, the second gear 31, the first worm 8, and the second worm 32 are all made of metal materials, specifically powder metallurgy materials, which have the characteristics of high strength and wear resistance. The first gear 4 meshes with the second worm 32 for transmission, and the second gear 31 meshes with the first worm 8 for transmission, ensuring the stability and reliability of the transmission, thereby improving the service life of the transmission components.

[0046] Continue to refer to Figure 2 The socket 5 is configured as a helical tooth nut, the outer ring of the rotating part 6 is provided with external threads, and the inner ring of the socket 5 is provided with internal threads. The socket 5 and the rotating part 6 are threadedly connected. The driving part 2 drives the socket 5 to rotate through the transmission mechanism 3. The socket 5 and the rotating part 6 are threadedly connected, so that the rotating part 6 can move linearly relative to the socket 5 along its own axis. The circular motion of the driving part 2 is converted into the linear reciprocating motion of the rotating part 6, thereby achieving the effect of retractable and concealed door handle.

[0047] Continue to refer to Figure 2 The housing 1 has a limiting groove 11, and the socket 5 is rotatably disposed in the limiting groove 11. Both the socket 5 and the housing 1 are made of plastic material, which has good sound insulation and shock absorption performance. The plastic socket 5 is tightly fitted with the plastic housing 1 through the limiting part to form a good sealing and shock absorption system, while reducing the friction and wear between the two.

[0048] Example 2

[0049] This embodiment provides a concealed door handle actuator, which has a structure that is basically the same as that of Embodiment 1, except that the fixing method of the socket 5 and the first gear 4 is different.

[0050] In this embodiment, the first gear 4 and the sleeve 5 are integrally formed by insert injection molding, so that the first gear 4 is fixed relative to the sleeve 5, reducing the wear between the first gear 4 and the sleeve 5 during transmission and effectively improving the service life.
