[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figure 1 A split nut structure includes a first nut 1, a second nut 2, and a clamp 3; the clamp 3 is fitted around the first nut 1 and the second nut 2 to form a cylindrical space; after being assembled with the push rod of the door handle actuator, the first nut 1 and the second nut 2 are connected with a gap through the clamp 3.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: This utility model improves the traditional nut structure into a split structure and connects it with a clamp, so that when there is an internal threaded part, the two nuts can clamp the internal threaded part (push rod) while having a certain gap between them, which can effectively improve the problems of movement and noise during use.

[0021] In one or more embodiments, the clamp 3 is an integral elastic clamp. The elastic clamp can be a spring, such as a coil spring, or as described above. Figure 4It is a structure similar to a spring, but unlike a spring where there are gaps between the coils, it is made of tightly wound round steel without gaps between the coils. The elastic hoop is made of metal and can provide a certain amount of deformation space, but it can also allow the first nut and the second nut to form a gapped connection when there is an internally threaded part (such as a push rod). That is, the internally threaded part has a larger diameter, which is larger than the diameter of the space formed when the two nuts are assembled with no gaps.

[0022] Please refer to Figure 2 and 3 In one or more embodiments, the first nut 1 has a protrusion 4 or a recess 5, and the second nut has a recess 5 or a protrusion 4 that is adapted to the protrusion 4 or recess 5 of the first nut.

[0023] As can be seen from the above description, the first nut and the second nut achieve a convex-concave fit through the cooperation of their respective concave and convex parts.

[0024] Please refer to Figure 2 and 3 In one or more embodiments, both the first nut 1 and the second nut 2 are provided with a first groove 6 for accommodating part of the clamp. By providing the first groove, the clamp can be axially limited, preventing the clamp from shifting or falling off in the axial direction.

[0025] Please refer to Figure 2 and 3 In one or more embodiments, both the first nut 1 and the second nut 2 are provided with anti-rotation ribs 7. After installation, the anti-rotation ribs cooperate with the housing to fix it inside the housing and prevent it from rotating.

[0026] Please refer to Figure 2 and 3 In one or more embodiments, the first nut 1 and the second nut 2 are respectively provided with anti-rotation ribs 7 on the end and the outer side wall.

[0027] As described above, setting multiple anti-rotation ribs in multiple directions can improve the stability of the fixation, ensuring that both nuts can be firmly set without moving.

[0028] Please refer to Figures 5-7 A door handle actuator includes an upper housing and a lower housing 9, a push rod 8 disposed within the space enclosed by the upper housing and the lower housing 9, and any of the aforementioned split nut structures; the push rod 8 and the split nut structure are connected by threads.

[0029] In one or more embodiments, the push rod 8 includes a first threaded section 801, a second threaded section 802, and a push rod section 803 connected in sequence. The first threaded section 801 is threadedly connected to a first nut 1 and a second nut 2. The first threaded section has external threads that match the internal threads of the two nuts. The second threaded section has external threads that match the transmission assembly (worm gear assembly) of the door handle actuator.

[0030] Please refer to Figure 7 and 8 A door handle actuator includes an upper housing and a lower housing 9, a push rod disposed within the space enclosed by the upper housing and the lower housing 9, and a split nut structure; the push rod 8 and the split nut structure are connected by threads. The split nut structure includes a first nut 1, a second nut 2, and a clamp 3; the clamp 3 is sleeved around the first nut 1 and the second nut 2 to form a cylindrical space between the first nut 1 and the second nut 2; the first nut 1 and the second nut 2 are connected with a gap through the clamp 3, and both the first nut 1 and the second nut 2 are provided with a first groove 6 for accommodating part of the clamp 3. Both the upper and lower housings 9 are provided with a second groove 10 to accommodate the remaining part of the clamp.

[0031] As can be seen from the above description, the first groove and the second groove work together to accommodate and limit the clamp.

[0032] Please refer to Figure 7 and 8 A door handle actuator includes an upper housing and a lower housing, a push rod disposed within the space enclosed by the upper housing and the lower housing, and a split nut structure; the push rod and the split nut are connected by threads. The split nut structure includes a first nut 1, a second nut 2, and a clamp 3; the clamp 3 is sleeved around the first nut 1 and the second nut 2 to form a cylindrical space between the first nut 1 and the second nut 2; both the first nut 1 and the second nut 2 are provided with anti-rotation ribs 7; The upper and lower shells 9 are respectively provided with a third groove 11 to accommodate and restrict the movement of the anti-rotation rib 7.

[0033] As described above, the third groove is designed to limit the anti-rotation ribs, thereby ensuring that both nuts are securely positioned in a fixed location between the two housings without moving.
