Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0026] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that any of the embodiments described herein can be incorporated in a combination of embodiments.

[0027] The door handle actuator and the vehicle provided by the utility model are described in detail below in combination with the embodiments.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a structural schematic diagram of an embodiment of the door handle actuator of the application; Figure 2 is an exploded schematic diagram of an embodiment of the door handle actuator of the application; Figure 3 is a first cross-sectional schematic diagram of an embodiment of the door handle actuator of the application. The utility model provides a door handle actuator. The door handle actuator 10 can act on a handle actuating mechanism, and then eject a handle (not shown in the figure), thereby facilitating the user to open the door, etc. The door handle actuator 10 comprises a housing 11, a driving mechanism 12, an actuating mechanism 13 and a transmission mechanism 14. The housing 11 comprises a first housing 111, a second housing 112 and a coaxial support 113. The first housing 111 and the second housing 112 are connected. Among them, the first housing 111 and the second housing 112 are detachably connected or fixedly connected. When the first housing 111 and the second housing 112 are connected, a containing space 114 is formed between the first housing 111 and the second housing 112. The containing space 114 is used for installing the above-mentioned driving mechanism 12, actuating mechanism 13 and transmission mechanism 14, etc. The coaxial support 113 is arranged in the second housing 112. Among them, the coaxial support 113 can be detachably or fixedly connected in the second housing 112. As in the embodiment, the coaxial support 113 is welded or integrally formed in the second housing 112.

[0029] The driving mechanism 12 is arranged in the containing space 114. Among them, the driving mechanism 12 can be detachably or fixedly connected in the containing space 114. The driving mechanism 12 is used for providing driving force. Among them, the driving mechanism 12 can be but is not limited to a driving motor 121, etc. The actuating mechanism 13 is arranged in the containing space 114. Among them, the actuating mechanism 13 can be detachably or fixedly connected in the containing space 114. The actuating mechanism 13 can be extended out of the housing 11 or retracted into the housing 11. When the actuating mechanism 13 is at least partially extended out of the housing 11, the actuating mechanism 13 drives the handle actuating mechanism, which is used for ejecting the handle. When the actuating mechanism 13 is at least partially retracted into the housing 11, the actuating mechanism 13 releases the driving force of the handle actuating mechanism.

[0030] The transmission mechanism 14 comprises a transmission deceleration rod 141, a first transmission part 142 and a second transmission part 143. The first transmission part 142 and the second transmission part 143 are connected to the transmission deceleration rod 141. The transmission deceleration rod 141 is coaxially defined between the coaxial support 113 and the second shell 112 at both ends. Among them, one end of the transmission deceleration rod 141 is defined in the coaxial support 113; the other end of the transmission deceleration rod 141 is defined in the second shell 112. The first transmission part 142 is meshingly connected with the driving mechanism 12, that is, the driving mechanism 12 can drive the first transmission part 142 to rotate. The second transmission part 143 is meshingly connected with the executing mechanism 13. In the process of rotating the first transmission part 142, the first transmission part 142 drives the second transmission part 143 to rotate, and then the second transmission part 143 can drive the executing mechanism 13 to move.

[0031] By providing the coaxial support 113 on the second shell 112, the transmission deceleration rod 141 of the transmission mechanism 14 is coaxially defined between the coaxial support 113 and the second shell 112 at both ends, which can ensure the axial accuracy of the transmission deceleration rod 141, improve the stability of the meshing connection between the transmission mechanism 14 and the driving mechanism 12 and the executing mechanism 13, and further reduce the occurrence of abnormal sound and the like.

[0032] Please refer to Figure 4 , Figure 4 is a structural schematic view of the second shell and the coaxial support in the door handle actuator of the present application. In combination with Figures 1 to 3 , specifically, the coaxial support 113 is provided with a first connecting hole 1131. The second shell 112 is provided with a second connecting hole 1122. One end of the transmission deceleration rod 141 is connected to the first connecting hole 1131. The other end of the transmission deceleration rod 141 is connected to the second connecting hole 1122. Through the cooperation of the transmission deceleration rod 141, the first connecting hole 1131 and the second connecting hole 1122, the axial accuracy of the transmission deceleration rod 141 is ensured, and the occurrence of abnormal sound and the like is further reduced.

[0033] In some embodiments, the first transmission part 142 is a transmission worm gear 1421. The transmission worm gear 1421 is connected to the transmission deceleration rod 141. Among them, the transmission worm gear 1421 is meshingly connected with the driving mechanism 12. The second transmission part 143 is a transmission worm 1431. The transmission worm 1431 is connected to the transmission deceleration rod 141. Among them, the transmission worm 1431 is meshingly connected with the executing mechanism 13. The transmission worm gear 1421 is located above the transmission worm 1431. By limiting the setting position of the above-mentioned transmission worm gear 1421 and transmission worm 1431, the meshing stability between the transmission mechanism 14 and the executing mechanism 13 and the driving mechanism 12 is improved, and the occurrence of abnormal sound and the like is further reduced.

[0034] In some embodiments, the transmission deceleration rod 141 is obliquely arranged between the coaxial support 113 and the second housing 112. The transmission deceleration rod 141 is obliquely arranged towards the extension direction of the driving mechanism 12. By arranging the transmission deceleration rod 141 in the above manner, not only the engagement stability between the transmission mechanism 14 and the actuating mechanism 13 and the driving mechanism 12 is ensured, but also the height of the transmission mechanism 14 itself is reduced, thereby reducing the overall height of the door handle actuator 10.

[0035] In some embodiments, the transmission deceleration rod 141 is a metal transmission deceleration rod or an alloy transmission deceleration rod. The metal transmission deceleration rod is made of metal material. Alternatively, the alloy transmission deceleration rod is made of alloy material. The metal transmission deceleration rod or the alloy transmission deceleration rod can improve the axial rigidity of the transmission mechanism 14.

[0036] In some embodiments, the first transmission part 142 is a plastic transmission worm gear. The plastic transmission worm gear is made of plastic material. The second transmission part 143 is a plastic transmission worm. The plastic transmission worm is made of plastic material. The plastic transmission worm gear and the plastic transmission worm can reduce the production cost while ensuring the engagement. The plastic transmission worm gear and the plastic transmission worm are connected to the metal transmission deceleration rod or the alloy transmission deceleration rod, which can also improve the axial rigidity of the plastic transmission worm gear and the plastic transmission worm.

[0037] In some embodiments, the first transmission part 142 and the second transmission part 143 are an integral structure. That is, the first transmission part 142 and the second transmission part 143 are one component. By limiting the first transmission part 142 and the second transmission part 143 to be an integral structure, the assembly of the transmission mechanism 14 is facilitated.

[0038] In some embodiments, the first transmission part 142 and the second transmission part 143 are detachably connected to the transmission deceleration rod 141, which facilitates assembly.

[0039] Please refer to Figure 5 and Figure 6 , Figure 5 is a partial explosion schematic view of an embodiment of the door handle actuator of the present application; Figure 6 is a second cross-sectional view of an embodiment of the door handle actuator of the present application. In combination with Figures 1 to 4 In some embodiments, the actuating mechanism 13 includes an actuating driving rod 131 and an actuating transmission rod 132. The actuating driving rod 131 is threadedly connected between at least part of the outer periphery and the inner surface of the actuating transmission rod 132. The actuating driving rod 131 is engaged with the second transmission part 143. The second transmission part 143 drives the actuating driving rod 131 to rotate, and the actuating driving rod 131 drives the actuating transmission rod 132 to move linearly, so that the actuating transmission rod 132 extends out of the housing 11 or retracts into the housing 11.

[0040] The end of the execution driving rod 131 is provided with a driving support part 1311. The end of the execution driving rod 131 is the end away from the second transmission part 143. The driving support part 1311 is detachably or fixedly connected to the execution driving rod 131. In this embodiment, the driving support part 1311 is welded or integrally formed on the execution driving rod 131. The bottom of the execution transmission rod 132 is provided with a first sliding groove (not shown in the figure). The second shell 112 is provided with a support seat 1121. The support seat 1121 is detachably or fixedly connected to the end of the second shell 112 facing the accommodation space 114. In this embodiment, the support seat 1121 is welded or integrally formed on the second shell 112. The first sliding groove provides a space for the support seat 1121. The support seat 1121 passes through the first sliding groove and supports the driving support part 1311.

[0041] Through the cooperation of the execution driving rod 131, the execution transmission rod 132, the driving support part 1311, the support seat 1121 and the first sliding groove, the end of the execution driving rod 131 can be supported, the risk of bending of the execution driving rod 131 can be reduced, the stability of the movement between the execution driving rod 131 and the execution transmission rod 132 can be improved, and the shaking and the like can be reduced.

[0042] The execution driving rod 131 is provided with external threads at least partially around the outer periphery (not shown in the figure). The inner surface of the execution transmission rod 132 is provided with internal threads (not shown in the figure). The external threads on the execution driving rod 131 and the internal threads on the execution transmission rod 132 are threadedly connected.

[0043] Specifically, the support seat 1121 is provided with a support groove 11211. The shape of the support groove 11211 matches at least part of the shape of the driving support part 1311, which can further improve the stability of the support groove 11211 supporting the driving support part 1311, and reduce the occurrence of shaking problems. In this embodiment, when the cross-sectional shape of the driving support part 1311 perpendicular to the extension direction is circular, the shape of the support groove 11211 is semicircular, and the driving support part 1311 and the support groove 11211 are circularly matched.

[0044] In some embodiments, the first shell 111 is provided with a crimping part 1111. The crimping part 1111 is detachably or fixedly connected to the end of the first shell 111 facing the accommodation space 114. In this embodiment, the crimping part 1111 is welded or integrally formed on the first shell 111. The upper part of the execution transmission rod 132 is provided with a second sliding groove 1322. The second sliding groove 1322 provides a space for the crimping part 1111. The crimping part 1111 passes through the second sliding groove 1322 and crimps the driving support part 1311 on the support seat 1121.

[0045] By the cooperation of the first shell 111, the crimping portion 1111, the execution transmission rod 132 and the second sliding groove 1322, the end of the execution drive rod 131 can be limited, the risk of bending of the execution drive rod 131 can be reduced, the stability of the movement between the execution drive rod 131 and the execution transmission rod 132 can be further improved, and the occurrence of shaking and the like can be reduced. In addition, the conversion of the rotary movement into the linear movement is more stable, and the risk of rotation is reduced.

[0046] Specifically, the first sliding groove and the second sliding groove 1322 are oppositely arranged and are in the shape of long grooves. By the first sliding groove in the shape of a long groove, the support seat 1121 can be provided with a space for avoiding interference with the extension or retraction movement of the execution drive rod 131. By the second sliding groove 1322 in the shape of a long groove, the crimping portion 1111 can be provided with a space for avoiding interference with the extension or retraction movement of the execution drive rod 131.

[0047] In addition, the first sliding groove and the second sliding groove 1322 have the same extension length as the movement distance of the execution transmission rod 132, which can limit the length of the movement path of the execution transmission rod 132, and avoid the execution drive rod 131 from being excessively extended or retracted into the shell 11. The first sliding groove and the second sliding groove 1322 can be, but are not limited to, a waist-shaped hole and the like.

The driving worm 123 and the transmission worm gear 1421 are meshingly connected.

[0049] By the cooperation of the driving motor 121, the driving shaft 122, the driving worm 123 and the transmission worm gear 1421, the driving motor 121 drives the driving worm 123 on the driving shaft 122 to rotate, the driving worm 123 drives the transmission worm gear 1421 to rotate, and the transmission worm gear 1421 drives the transmission worm 1431 to rotate, thereby achieving the meshing connection between the driving mechanism 12 and the transmission mechanism 14.

[0050] In some embodiments, the execution drive rod 131 is provided with an execution worm gear 1312. The execution worm gear 1312 is detachably or fixedly connected to the outer periphery of the execution drive rod 131.
