[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] The existing technology has the technical problem that the vertical lever is prone to breakage and accidental activation during operation.

[0019] Therefore, this application provides a control device, wherein the control device includes... A translation component and a fixed component, wherein the translation component can move parallel to the fixed component in at least one direction; A motion conversion component is located at the bottom of the translation component along a first direction. The translation component is connected to the motion conversion component in a transmission manner and drives the motion conversion component to swing around a rotation axis. The motion conversion assembly has sensors on both sides of the rotation axis. When the motion conversion assembly swings, it selectively contacts one of the sensors on one side of the rotation axis and sends a control signal.

[0020] Example 1: In the current technology, with the development of the automotive industry, improving the comfort and convenience of vehicle interiors has become an important design direction. Among many in-vehicle components, the reliability and user experience of seat adjustment devices are particularly critical. Currently, most seats on the market are adjusted by swinging a vertical lever. While this design is simple in structure, it has several shortcomings in practical use. Because the lever protrudes vertically from the seat adjustment device and adjusts the seat by rotation, it is prone to breakage due to frequent operation, affecting the normal use of the seat adjustment function. Secondly, some existing levers lack anti-accidental touch design, and adding such design would make the overall structure of the lever more complex. While driving, the driver's natural body movements or the need to quickly adjust the seating position in an emergency may accidentally touch the lever, leading to accidental activation.

[0021] Please refer to the attached document. Figure 1 To be continued Figure 7 As shown, the first direction X of this application is the height direction of the control device 10, that is, the direction of the control device 10 from top to bottom or from bottom to top.

In this application, the translation component 100 can realize movement in at least one direction, and the motion conversion component 300 can rotate around at least one rotation axis. In one embodiment, the translation component 100 can realize translational movement along the second direction Y and the third direction Z.

The two drive slots and one drive slot are sequentially arranged along the second rotation axis 340, and the two second drive slots 112 are arranged along a third direction Z on the first moving member 110. The first drive slot 111 is located between the two second drive slots 112. The projection of the first rotation axis 320 along the first direction X onto the first moving member 110 intersects with the first drive slot 111. Further structures of the first drive slot 111 and the second drive slot 112 will be described in the appendix. Figure 3 Further explanation is provided below.

[0031] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the first motion conversion component 310 of this application includes a first drive seat 311 and a first drive rod 312. The first drive rod 312 is disposed along a first direction X and is connected to the first drive seat 311.

The specific control process will be further explained in the following figures.

[0033] Please refer to the attached document. Figure 1 and appendix Figure 2As shown, the second motion conversion component 330 of this application includes a second drive seat 331 and a second drive rod 332.

[0034] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the control device 10 of this application also includes sensors for identifying the swing direction of the first motion converter 310 and the second motion converter 330. Two sets of sensors are provided: a first sensing assembly and a second sensing assembly.

The second sensing assembly includes two second sensors, respectively disposed on both sides of the second rotation axis 340 and corresponding to the second contact position 333. Under the swing of the motion converter 300, the motion converter 300 selectively contacts one of the sensors on one side of the rotation axis and sends a control signal.

[0035] Specifically, when the translation component 100 moves along the third direction Z and to the left, it synchronously drives the first motion conversion component 310 to deflect to the left around the first rotation axis 320 and make contact with the first sensor to send a control signal. This control signal can be for the seat to move backward. When the translation component 100 moves along the third direction Z and to the right, it synchronously drives the first motion conversion component 310 to deflect to the right around the first rotation axis 320 and make contact with the first sensor to send a control signal. This control signal can be for the seat to move forward. When the translation component 100 moves forward along the second direction Y, it synchronously drives the second motion conversion component 330 to deflect forward around the second rotation axis 340 and make contact with the second sensor to send a control signal. This control signal can be for the seat to move upward. When the translation component 100 moves backward along the second direction Y, it synchronously drives the second motion component to deflect backward around the second rotation axis 340 and make contact with the second sensor to send a control signal. This control signal can be for the seat to move downward. The specific meaning of the control signal is determined based on the specific assembly of the control device 10. Under different assembly conditions, the direction of seat movement may vary.

[0036] In one embodiment, both the first and second sensors are provided with elastic pads to help the first motion converter 310 and the second motion converter 330 return to their original positions, respectively.

[0037] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the control device 10 of this application also includes a first limiting member 400, which is disposed between the first moving plate 120 and the second fixed plate 220 to form a limit on the first moving plate 120 in the second direction Y and the third direction Z.

[0038] In one embodiment, the first limiting member 400 includes a first limiting groove 410 and a first limiting post 420. The first limiting groove 410 is disposed on one of the first moving plate 120 and the second fixed plate 220, and the first limiting post 420 is disposed on the other of the first moving plate 120 and the second fixed plate 220. The first limiting post 420 extends along a first direction X into the first limiting groove 410, and forms a limiting relationship with the first limiting groove 410 along a second direction Y and a third direction Z.

[0039] Appendix Figure 3 This is a schematic diagram of a structure between the first moving member 110 and the first moving plate 120 of this application. Please refer to the attached diagram. Figure 3 As shown, the first driving groove 111 includes two first driving surfaces 111-1 spaced apart along a third direction Z, and two first connecting surfaces 111-2 spaced apart along a second direction Y. The first driving groove 111 is enclosed by the two first driving surfaces 111-1 and the two first connecting surfaces 111-2, and the distance between the two first driving surfaces 111-1 is smaller than the distance between the two first connecting surfaces 111-2. The second driving groove 112 includes two second driving surfaces 112-1 spaced apart along a second direction Y, and two second connecting surfaces 112-2 spaced apart along a third direction Z. The second driving groove 112 is enclosed by the two second driving surfaces 112-1 and the two second connecting surfaces 112-2, and the distance between the two second driving surfaces 112-1 is smaller than the distance between the two second connecting surfaces 112-2.

[0040] Appendix Figure 4 This is a top view of the control device 10 of this application. (Attached) Figure 4 In order to further demonstrate the appendix Figure 5 To be continued Figure 7 The cross-section. (Attached) Figure 4 It contains three cross-sections, namely AA, BB, and CC, where AA is an auxiliary cross-section. Figure 5 The cross-section, BB is attached Figure 6 The cross-section, CC is attached. Figure 7 The cross-section.

[0041] Please refer to the attached document. Figure 3 and appendix Figure 5 To be continued Figure 7As shown, when the translation component 100 moves along the third direction Z, the third driving surface 312-1 on the first driving rod 312 abuts against the first driving surface 111-1, and at this time the second driving rod 332 is in the second driving groove 112, and there is always a gap between the second driving rod 332 and the second connecting surface 112-2. Therefore, the movement of the translation component 100 along the third direction Z can only drive the first motion conversion component 310 to form a corresponding swing, and the area between the two second connecting surfaces 112-2 further limits the stroke of the translation component 100 along the third direction Z. When the translation component 100 moves along the second direction Y, the fourth driving surface 332-1 on the second driving rod 332 abuts against the second driving surface 112-1. At this time, the first driving rod 312 is in the first driving groove 111, and there is always a gap between the first driving rod 312 and the first connecting surface 111-2. Therefore, the movement of the translation component 100 along the second direction Y can only drive the second motion conversion component 330 to form a corresponding swing, and the area between the two first connecting surfaces 111-2 further determines the movement stroke of the translation component 100 along the second direction Y.
