The present utility model relates to door handles, and more particularly to concealed door handles. Typically, a door handle is mounted to a sheet metal part of a vehicle body and has an ejected position relative to an outward projection of the sheet metal part and a hidden position flush with the sheet metal part. Fig. 1-3 illustrate one embodiment of an actuation assembly for a door handle, the actuation assembly 100 shown including a housing 20, an actuator 30 disposed within the housing 20, a conductive strip 40 drivingly connected to the actuator 30, and a terminal set 50 mated with the conductive strip 40. When the handle is in the ejecting position, the terminal group 50 outputs a first signal S1; when the handle is in the hidden position, the terminal set 50 outputs a second signal S2. The terminal set 50 is connected with the vehicle body controller in a feedback manner, and the controller judges whether the handle is at the ejecting position or the hiding position according to signals S1 and S2 of the terminal set 50 and coordinates the operation of each corresponding device accordingly.

Referring to fig. 4 and 6, the terminal set 50 includes a first terminal 51, a second terminal 52, and a third terminal 53 disposed at intervals. The first terminal 51 has two ends respectively forming a first conductive end 51A and a first connection end 51B, the second terminal 52 has two ends respectively forming a second conductive end 52A and a second connection end 52B, and the third terminal 53 has two ends respectively forming a third conductive end 53A and a third connection end 53B. The first conductive end 51A and the third conductive end 53A together form a first conductive structure, and the first connection end 51B and the third connection end 53B together form a first output port; the second conductive end 52A and the third conductive end 53A together form a second conductive structure; the second connection end 52B and the third connection end 53B together form a second output port. The first output port and the second output port are used for being connected with corresponding ports of the controller.

The conductive sheet 40 is preferably a metal sheet having excellent conductive properties. More preferably, the conductive sheet 40 is an elastic metal sheet elastically abutting against the conductive structure of the terminal set 50. The conductive sheet 40 is linearly movable between a first position and a second position in a first direction (i.e., the X-direction as shown) upon actuation of the actuator 30. When the handle is in the ejecting position, the conductive sheet 40 moves to the first position, turns on the first conductive structure (i.e., turns on the first and third conductive terminals 51A and 53A), and the first output port (i.e., the first and third connection terminals 51B and 53B) outputs the first signal S1. When the handle is in the hidden position, the conductive tab 40 moves to the second position, turning on the second conductive structure (i.e., turning on the second and third conductive ends 52A, 53A). At this time, the second output port (i.e., the second and third connection terminals 52B, 53B) outputs the second signal S2.

In the present embodiment, the first conductive terminals 51A, the second conductive terminals 52A are arranged at intervals in the first direction; the third conductive end 53A is disposed parallel to and spaced apart from the first conductive end 51A and the second conductive end 52A. The length of the third conductive end 53A in the first direction corresponds to the sum of the lengths of the first conductive end 51A and the second conductive end 52A in the first direction. Thus, the third conductive end 53A is partially (e.g., trailing) opposite the first conductive end 51A and partially (e.g., leading) opposite the second conductive end 52A.

The first, second and third connection ends 51B, 52B, 53B are disposed side by side and extend out of the housing 20. Accordingly, the housing 20 has terminal housings extending outwardly around the respective connection ends 51B, 52B, 53B for quick connection to a controller by plugging.

As shown in fig. 5, the conductive sheet 40 extends obliquely toward the side of the terminal group 50 with the first conductive portion 42 and the second conductive portion 44, and the first conductive portion 42 and the second conductive portion 44 are arranged at intervals in a second direction (i.e., Y direction in the drawing) perpendicular to the first direction. The end of the first conductive portion 42 is bent to form a first abutting portion 421, and the end of the second conductive portion 44 is bent to form a second abutting portion 441. The first and second abutting portions 421, 441 are substantially parallel to the first, second, and third conductive ends 51A, 52A, 53A of the terminal group 50. Preferably, the first abutting portion 421 and the second abutting portion 441 are respectively formed with a first contact 423 and a second contact 443 protruding toward the side surface of the terminal group 50, and the first contact 423 and the second contact 443 are preferably hemispherical.

As shown in fig. 8-9, when the conductive sheet 40 is in the first position, the first contact 423 of the first conductive portion 42 elastically abuts against the first conductive end 51A, and the second contact 443 of the second conductive portion 44 elastically abuts against the tail end of the third conductive end 53A, so that the first terminal 51 and the third terminal 53 are electrically connected, and the first signal S1 is output. As shown in fig. 10 to 11, when the conductive sheet 40 is in the second position, the first contact 423 of the first conductive portion 42 elastically abuts against the second conductive end 52A, and the second contact 443 of the second conductive portion 44 elastically abuts against the front end of the third conductive end 53A, so that the second terminal 52 and the third terminal 53 are electrically connected, and the second signal S2 is output. Preferably, the first conductive portion 42 and the second conductive portion 44 are slightly deformed after being assembled, so as to form a pre-tightening force between the conductive sheet 40 and the terminal set 50, thereby ensuring the contact tightness between the conductive sheet 40 and the terminal set, and ensuring the electrical conduction of the corresponding conductive structure.

In this embodiment, the housing 20 includes a case 22 and a cover 24 closing the case 22, which together form a closed installation space. The conductive sheet 40 is movably disposed in the housing 22, and the terminal set 50 is fixedly disposed in the housing 22. Preferably, the terminal set 50 is of non-removable unitary construction with the housing 22. During production, the terminals 51, 52 and 53 are placed at corresponding positions in the mold after molding, then the shell 22 is molded by injection, and the shell 22 covers the middle parts of the terminals 51, 52 and 53 in the molding process to fix the terminals integrally, so that the stability of connection is improved, and the subsequent assembly process is simplified. In other embodiments, it should be understood that the terminals 51, 52, 53 of the terminal set 50 may also be fixedly connected to the housing 22 by plugging, bonding, etc. after being formed, so long as the electrical connection with the conductive sheet 40 is not affected.

As shown in fig. 3, the first conductive end 51A, the second conductive end 52A, and the third conductive end 53A are embedded in the housing 22, and the inner wall surface of the housing 22 is opened at a position corresponding to the first conductive end 51A, the second conductive end 52A, and the third conductive end 53A, so that the surfaces of the first conductive end 51A, the second conductive end 52A, and the third conductive end 53A are exposed. In this way, the first conductive portion 42 and the second conductive portion 44 of the conductive sheet 40 can be brought into contact with the first conductive terminal 51A, the second conductive terminal 52A, and the third conductive terminal 53A to conduct them. Preferably, the exposed surfaces of the first conductive end 51A, the second conductive end 52A, and the third conductive end 53A are flush with the inner wall surface of the housing 22. In this way, the arrangement of the terminal set 50 does not occupy the internal space of the housing 22 substantially, and does not affect the installation and arrangement of other components.

In the present embodiment, the housing 22 is provided therein with a guide groove 26, and the guide groove 26 extends in the first direction. The first conductive end 51A, the second conductive end 52A, and the third conductive end 53A are disposed at the bottom of the guide groove 26. A slider 28 is provided in the guide groove 26, and the slider 28 is slidable along the guide groove 26 in the first direction. The conductive tab 40 is fixedly attached to the outer wall of the slider 28 and the two may be adhered, welded, snap-fit, interference fit, etc. In the illustrated embodiment, the outer wall of the sliding member 28 is formed with a positioning protrusion 281, and the positioning protrusion 281 is generally square and abuts against the groove walls at two sides of the guiding groove 26 to limit the rotation of the sliding member 28 relative to the housing 22, so that the sliding member 28 can only move linearly relative to the housing 22. The positioning bump 281 protrudes toward one side of the conductive plate 40 to form a protruding post 283, the conductive plate 40 is provided with a clamping hole 46, and the protruding post 283 is clamped in the clamping hole 46 to fixedly connect the conductive plate 40 with the sliding member 28.

The actuator 30 is fixedly disposed within the housing 22, preferably a motor, such as a DC brushless motor, stepper motor, or the like. The actuator 30 and the slider 28 are connected by a transmission unit 32, and in this embodiment, the transmission unit 32 includes a worm 33 connected to an output shaft 31 of the actuator 30, a plurality of gears 34 engaged with the worm 33, a screw 35 pivotally connected to the gears 34, and the like. When the actuator 30 is activated, the screw 35 is driven to rotate at an appropriate speed by the worm 33, the gear 34, and the like. As shown in fig. 7 and 7a, the sliding member 28 is sleeved on the screw rod 35 and is screwed with the screw rod 35. Since the positioning protrusion 281 is limited by the groove walls at two sides of the guiding groove 26, the sliding member 28 cannot rotate, so that the rotation of the screw rod 35 is converted into the linear movement of the sliding member 28 in the first direction, and the conductive sheet 40 is driven to move between the first position and the second position.

As shown in fig. 3, 4 and 6, the terminal set 50 further includes a fourth terminal 54 and a fifth terminal 55, the inner ends 54A, 55A of the fourth terminal 54 and the fifth terminal 55 penetrate through the inner wall surface of the housing 22 to be connected with the control end of the actuator 30, and the outer ends 54B, 55B extend out of the housing 22 to be connected with corresponding ports of the controller, so that the controller can control the operation of the actuator 30, including controlling the start and stop, turning, rotating speed, etc. of the actuator 30. In addition, the transmission unit 32 can realize the speed and torque reduction transmission of power and the change of the power transmission direction, and facilitates the arrangement of elements in the shell 22, so that the overall structure is more compact, and the specific structure can correspondingly change according to the size and the position of the installation space in the shell 22, so long as the sliding piece 28 and the conductive sheet 40 can linearly move. In some embodiments, the transmission unit 32 may also be omitted.

The inventive actuating assembly 100 is applied in door handles, in particular in concealed door handles, two output ports being formed by three terminals 51, 52, 53. When the conductive sheet 40 moves to the first position, the terminals 51 and 53 are conducted, and the first output port feeds back a first signal S1 to the controller; when the conductive sheet 40 moves to the second position, the terminals 52 and 53 are turned on, the second output port feeds back the second signal S2 to the controller, and the controller determines whether the handle is in the ejection position or the hidden position according to the signals S1 and S2, so as to control the operation of the related elements. The terminals 51, 52 and 53 can be integrally formed in the housing 22, so that the overall structure of the actuating assembly 100 is not affected basically, the production and the manufacture are convenient, the cost is low, the defect that the position of a handle is fed back by using a micro switch in the existing structure is effectively avoided, and the popularization and the application of products are facilitated.

It should be noted that the above examples merely represent preferred embodiments of the present utility model, and the description thereof is more specific and detailed, but should not be construed as limiting the utility model. It should be noted that it will be apparent to those skilled in the art that modifications and improvements can be made without departing from the spirit of the utility model, such as combining different features of the various embodiments, which are all within the scope of the utility model.
