Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to a window lift button. Background Technology

[0002] Automotive window systems have evolved from early manual crank-type systems. In the early days of automobiles, opening and closing windows relied entirely on manual operation. Drivers and passengers needed to turn a crank to raise or lower the window, a method that was not only time-consuming and laborious but also posed certain safety hazards while driving, especially at high speeds or in emergencies, as it was difficult to quickly adjust the window's position. With the continuous advancement of automotive technology, electric window systems emerged. Electric window systems use motors to drive the window glass up and down, greatly improving convenience and comfort. Drivers and passengers can simply press a window button to quickly raise or lower the window, eliminating the need for manual crank operation. This improvement significantly enhances the user experience.

[0003] A search revealed that Chinese patent CN222260853U discloses a window lift button. This button, through the cooperation of hook one, hook two and limiting baffle, makes the connection between the connector and the housing more secure and reliable, and makes subsequent maintenance and replacement more convenient and quick.

[0004] The aforementioned device lacks a reset mechanism for the button caps, causing the button caps to fail to reset automatically, which inconveniences the user. Therefore, we propose a window lift button. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] 1) This application sets up an elastic telescopic rod, and uses the telescopic end of the elastic telescopic rod to act on the limiting groove of the keycap. After the keycap is rotated, the telescopic end of the elastic telescopic rod can exert a force on the keycap in the opposite direction of rotation. In conjunction with the lifting switch with travel sensing, it is convenient for users to control the output signal of the lifting switch; and it can automatically reset after the keycap is released.

[0020] 2) This application inserts the connecting shaft of the rotating frame into the U-shaped groove of the bracket, so that when the keycap rotates, the bracket can drive the rotating frame to rotate to one side, and the rotating frame can press the lifting switch on one side for window lifting control.

[0028] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0029] Please see Figures 1 to 3 This application provides a technical solution:

[0030] A car window lift button includes a keycap 1, a support base 2, a rotating frame 3, an elastic telescopic rod 4, and a circuit board 5. The support base 2 is located below the keycap 1 and is rotatably connected to it. The rotating frame 3 is rotatably mounted on the lower part of the support base 2. The circuit board 5 is located below the rotating frame 3, and the support base 2 is connected and fixed to the circuit board 5. At least two sets of lift switches 501 are installed on the circuit board 5, and the two sets of lift switches 501 are respectively arranged on both sides of the lower part of the rotating frame 3. A bracket 101 is fixedly connected to the lower part of the keycap 1. The lower part of the bracket 101 passes through the support base 2, and a U-shaped groove 102 is opened at the end of the bracket 101. The U-shaped groove 102 is inclined. A connecting shaft 301 is fixedly connected to the rotating frame 3. The connecting shaft 301 is offset from the rotation axis of the rotating frame 3 and is slidably inserted into the U-shaped groove 102. The elastic telescopic rod 4 is fixedly mounted on the support base 2, and the telescopic end of the elastic telescopic rod 4 abuts against the keycap 1. In the static state, the axis of the elastic telescopic rod 4 and the rotation axis of the keycap 1 are located in the same plane.

[0031] In use, rotating the keycap 1 causes the bracket 101 to rotate to one side. The inner wall of the U-shaped groove 102 pushes the connecting shaft 301 to one side, thereby driving the rotating frame 3 to rotate. This allows the rotating frame 3 to contact a set of lifting switches 501. When the lifting switches 501 are pressed by the rotating frame 3, they output a control signal to control the raising and lowering of the car window. Preferably, each set of lifting switches 501 has two switches. After releasing the keycap 1, the elastic telescopic rod 4 acts on the keycap 1 to reset it, facilitating the user's adjustment of the car window position.

[0032] like Figure 4 As shown, a limiting groove 103 is provided at the lower part of the keycap 1. The telescopic end of the elastic telescopic rod 4 abuts against the middle of the limiting groove 103. The inner walls on both sides of the limiting groove 103 protrude away from the axis of rotation of the keycap 1. When the keycap 1 rotates to either side relative to its axis of rotation, the telescopic end of the elastic telescopic rod 4 will slide along the inner wall of the limiting groove 103 and be compressed. As the rotation amplitude of the keycap 1 increases, the elastic telescopic rod 4 is continuously compressed, and the force acting on the keycap 1 increases, which can provide force feedback to the user. In conjunction with the lift switch 501 with travel sensing, the user can easily control the output signal of the lift switch 501. At this time, the telescopic end of the elastic telescopic rod 4 exerts a force on the inner wall of the limiting groove 103 in the opposite direction to the rotation direction of the keycap 1. When the user releases the keycap 1, the keycap 1 will automatically return to its original position.

[0033] like Figure 5As shown, the support base 2 has a first clearance groove 201, and the rotating frame 3 is rotatably disposed within the first clearance groove 201. The support base 2 also has a second clearance groove 202, and the end of the bracket 101 passes through the second clearance groove 202 and is connected to the connecting shaft 301. The rotating frame 3 has a third clearance groove 302 in the middle, and the elastic telescopic rod 4 passes through the third clearance groove 302 and is connected and fixed to the support base 2. Preferably, there are two second clearance grooves 202, which are symmetrically distributed on both sides of the first clearance groove 201; there are two brackets 101, which pass through the two second clearance grooves 202 respectively and are connected to the connecting shafts 301 on both sides of the rotating frame 3.

[0034] like Figure 6 As shown, the elastic telescopic rod 4 includes a telescopic sleeve 401, a reset rod 402, and an elastic element 403. The reset rod 402 is slidably inserted into the telescopic sleeve 401, and the elastic element 403 is disposed between the telescopic sleeve 401 and the reset rod 402. The telescopic sleeve 401 is fixedly connected to the support base 2, and the reset rod 402 abuts against the keycap 1. Preferably, the elastic telescopic rod 4 is inclined to reduce the size of the device.

[0035] Preferably, the keycap 1 and the support base 2 are detachably connected. The keycap 1 and the support base 2 can be connected by a snap-fit ​​method. By providing rotating grooves on both sides of the keycap 1 and cylindrical locking blocks on both sides of the support base 2, the cylindrical locking blocks can be inserted into the rotating grooves of the keycap 1 by means of the elastic deformation capability of the support base 2, thus completing the installation of the keycap 1. If the keycap 1 is damaged, the user only needs to replace the keycap 1.
