FIG. 3 is a perspective view of door handle assembly 100 as shown in FIG. 1A with cover 106 in the open position. The lid 106 is shown in the closed position in fig. 1A-1B. The process of moving the lid 106 from the open position to the closed position, and the process of moving the lid from the closed position to the open position, are described below in conjunction with FIGS. 1A-1B and 3:

as shown in fig. 1A-1B, when the cover 106 is in the closed position, the second guide bar 134 is located at the right end of the first guide section 141, and the meshing portion of the rack gear 124 with the external gear 122 is located at the first end portion of the rack gear 124. The cover 106 is able to close the opening 302 and the door panel opening, and the outer surface (i.e., the front surface) of the cover 106 is flush with the outer surface of the door panel 101. The handle 107 is in the initial position.

When a user needs to open the door, the user sends a door opening signal to the control device 161 (for example, the user sends the door opening signal to the control device 161 through a mobile phone or other equipment), and the control device 161 activates the driving part 112. Drive member 112 rotates outer gear 122 in a first direction about axis X of outer gear 122. Since the rack gear 124 is engaged with the external gear 122, the rack gear 124 is moved by the rotation of the external gear 122. Since the rack 124 is connected to the cover 106, the rack 124 and the cover 106 can move relative to the housing 102 in cooperation with the guide assembly and the guide portion 103. Specifically, during the movement of the cover 106, first, the first guide rod 132 enters the second guide section 142 from the first guide section 141 and the second guide rod 134 moves in the first guide section 141, so that the left end of the cover 106 moves backward and leftward while the right end of the cover 106 moves only leftward. Then, the first guide rod 132 enters the second guide section 142 and the second guide rod 134 enters the second guide section 142 from the first guide section 141, so that the left end of the cover 106 moves only to the left while the right end of the cover 106 moves backward and to the left. Subsequently, the cover 106 reaches the open position (as shown in fig. 3), the first guide bar 132 is located at the left end of the third guide section 143, the engagement of the rack gear 124 with the external gear 122 is located at the second end of the rack gear 124, and the cover 106 is received in the receptacle 104, thereby exposing the opening 302. At this point, the user may extend his or her hand through opening 302 into cavity 104 and press down on handle 107 in the four directions. The handle 107 is rotated in a counterclockwise direction about the handle axis Y upon depression by the user, moving from the initial position to the pulled position. When the handle 107 is in the pulled position, the trigger portion of the trigger member 151 connected to the handle 107 contacts the sensing member 153, thereby causing the sensing member 153 to send a signal to the control device 161. The control 161 unlocks the door lock. As one example, the control device 161 can be coupled to a driver (not shown) that drives movement of a latch (not shown) to control movement of the driver to unlock the door. Thereby, the door lock is unlocked.

It should be noted that when the user presses the handle 107 in the four directions, the return member 152 is pre-tensioned. After the user presses handle 107, the user releases handle 107 and the fingers exit cavity 104 through opening 302. The handle 107 will return from the pulled position to the initial position by the pretensioned return member 152.

After the user releases the handle 107, the control device 161 activates the drive member 112 (e.g., the control device 161 is configured such that the control device 161 activates the drive member 112 after a period of time has elapsed since the sensor member 153 sent a signal to the control device 161). Drive member 112 rotates outer gear 122 about axis X in a second direction. Since the rack gear 124 is engaged with the external gear 122, the rack gear 124 is moved by the rotation of the external gear 122. Since the rack 124 is connected to the cover 106, the rack 124 and the cover 106 can move the cover 106 relative to the housing 102 under the cooperation of the guide assembly and the guide portion 103. The engagement of the guide assembly with the guide portion 103 during movement of the cover 106 from the open position to the closed position is opposite to the engagement of the guide assembly with the guide portion 103 during movement of the cover 106 from the closed position to the open position, and will not be described herein. Finally, the cover 106 closes the opening 302 and the door panel opening, and the cover 106 can be flush with the door panel 101.

It should be understood that although the trigger 151 and sensing 153 components are illustrated herein, other ways of unlocking the door lock by the handle 107 (e.g., the handle 107 being directly coupled to the latch pin) are within the scope of the present application.

It should be understood that although the present application illustrates the cover 106 as being positioned to the left of the opening 302 when the cover 106 is in the open position, in other embodiments, the cover 106 may be positioned to the right of the opening 302. That is, the cover 106 may be located on one side of the opening 302 in the longitudinal direction.

In the prior art, on the one hand, the cover of the door handle assembly is moved together with the housing while being rotated, thereby entering the cavity. On the other hand, after the cover enters the cavity, the handle and the cover are arranged oppositely. This arrangement requires a larger dimension (e.g., 10cm) in the depth direction, and therefore, the prior art door is thick and requires a large space.

In contrast, the cover in the present application moves in a manner of moving in the length direction, and thus requires a small space (for example, 4cm) in thickness. Furthermore, the handle is arranged below the opening, which is more suitable for the gripping/pressing manner of a human hand. In addition, the magnitude of the movement of the handle 107 can be reduced by the arrangement of the triggering part 151 and the sensing part 153, thereby further reducing the size of the door handle assembly 100.

While the present disclosure has been described in conjunction with examples of the embodiments outlined above, various alternatives, modifications, variations, improvements, and/or substantial equivalents, whether known or that are or may be presently foreseen, may become apparent to those of ordinary skill in the art. Additionally, the technical effects and/or technical problems described in this specification are exemplary rather than limiting; the disclosure in this specification may be used to solve other technical problems and have other technical effects and/or may be used to solve other technical problems. Accordingly, the examples of embodiments of the present disclosure set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit or scope of the disclosure. Accordingly, the present disclosure is intended to embrace all known or earlier-developed alternatives, modifications, variations, improvements, and/or substantial equivalents.
