[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0021] like Figures 1-4As shown, a locking device for a car window button includes a lock box 1, inside which a self-locking mechanism is provided; the self-locking mechanism includes a frame 201, vertical slots 202, a sliding plate 203, self-locking grooves 204, unlocking grooves 205, a compression spring 206, a locking rod 207, a sliding rod 208, a push rod 209, a telescopic spring 210, a car window button 211, and an unlocking button 212. The frame 201 is fixedly connected to the inside of the lock box 1. The three vertical slots 202 are all opened on the rear side of the frame 201. The sliding plate 203 is slidably connected to the inside of the frame 201. The two self-locking grooves 204 are all opened on the front side of the sliding plate 203. The unlocking groove 205 is opened on the sliding plate 206. The front side of the 3rd section is located on one side of the two self-locking grooves 204. One end of the compression spring 206 is fixedly connected to the inner wall of the lock box 1, and the other end of the compression spring 206 is fixedly connected to one side of the sliding plate 203. Two locking rods 207 are slidably connected to the inside of the vertical groove 202, and the two locking rods 207 are respectively located at the bottom of the inner wall of the self-locking groove 204. The sliding rod 208 is slidably connected to the inside of the vertical groove 202, and the sliding rod 208 is located at the top of the inner wall of the unlocking groove 205. One end of the push rod 209 is fixedly connected to the front end of the locking rod 207 and the sliding rod 208, and the other end of the push rod 209 passes through the frame 201 and extends to the top of the lock box 1. The telescopic spring 21... One end of each of the push rods 209 and the telescopic spring 210 is fixedly connected to the bottom of the inner wall of the frame 201. Two window buttons 211 are fixedly connected to the top of the two push rods 209 respectively. An unlock button 212 is fixedly connected to the top of one of the push rods 209. When the window buttons 211 need to be locked, the two window buttons 211 can be pressed down. Pressing the window buttons 211 down will push the two push rods 209 downwards and compress the telescopic spring 210 downwards. The downward movement of the push rods 209 simultaneously drives the two locking rods 207 downwards within the vertical groove 202, and under the inclined guidance of the self-locking groove 204, they can be squeezed... The sliding plate 203 moves to one side and presses against the compression spring 206, causing the two locking rods 207 to move downward inside the self-locking groove 204. When the two locking rods 207 reach the bottom of the inner wall of the self-locking groove 204, they can push the sliding plate 203 to slide in the opposite direction under the rebound of the compression spring 206, locking the two locking rods 207 in the groove at the bottom of the inner wall of the self-locking groove 204. Thus, the two push rods 209 and the two window buttons 211 can be locked by the locking rods 207. The operator cannot press the buttons or pull the window buttons 211 upwards, thus locking the window buttons 211 with a simple operation, improving the safety and reliability of the vehicle.
[0022] like Figures 2-3As shown, each push rod 209 has a fixedly connected movable rod 3 at its bottom end. The bottom end of each movable rod 3 passes through the frame 201 and extends to the bottom of the lock box 1. The movable rod 3 is movably disposed inside the telescopic spring 210. The movable rod 3 is slidably connected inside the frame 201. When the push rod 209 is pushed downward, the push rod 209 can drive the movable rod 3 to move downward and make the push rod 209 slide vertically inside the frame 201. The movable rod 3 can provide auxiliary guidance for the push rod 209, so that the push rod 209 can move vertically when moving up and down. This can drive the locking rod 207 and the sliding rod 208 to slide smoothly and improve the stability and reliability of the self-locking mechanism.
[0023] like Figures 3-4 As shown, sliders 401 are fixedly connected to the top and bottom of the sliding plate 203. The top and bottom of the inner side of the frame 201 are provided with grooves 402 that cooperate with the sliders 401. When the sliding plate 203 slides inside the frame 201, the sliding plate 203 will drive the slide plate to slide inside the groove 402. Under the guidance of the groove 402 and the slider 401, the sliding plate 203 can move in parallel, preventing the sliding plate 203 from deviating during movement and causing the self-locking mechanism to jam.
[0024] like Figures 2-3 As shown, there are two compression springs 206, which are equidistantly and vertically distributed on one side of the sliding plate 203. The two compression springs 206 can make the force distribution more uniform, avoid the single compression spring 206 being overloaded, which may lead to local deformation or failure. In addition, the equidistant compression springs 206 can provide more stable mechanical support during the sliding of the sliding plate 203, making the system more balanced when bearing load.
[0025] like Figure 4 As shown, both the locking rod 207 and the sliding rod 208 are fitted with limiting rings 5. The limiting rings 5 are located on the rear side of the frame 201. When the vertical rod and the sliding rod 208 slide inside the vertical groove 202, the locking rod 207 and the sliding rod 208 can be assisted in being limited inside the vertical groove 202 by the limiting rings 5, so as to prevent the locking rod 207 and the sliding rod 208 from disengaging or shifting inside the vertical groove 202 when sliding.
[0026] like Figures 2-3 As shown, both the frame 201 and the lock box 1 have a circular hole 6 at their bottom. The diameter of the circular hole 6 is adapted to the movable rod 3. When the push rod 209 moves the movable rod 3 downward, the push rod 209 will slide flexibly inside the circular hole 6, so that the movable rod 3 has sufficient room to move and can observe the frame 201 and the lock box 1. This prevents the movable rod 3 from colliding with the frame 201 and the lock box 1 during movement and causing motion interference.
[0027] The working principle of this utility model is as follows: When it is necessary to lock the window buttons 211, the two window buttons 211 can be pressed down first. After the window buttons 211 are pressed down, they will push the two push rods 209 downward and squeeze the telescopic spring 210 downward. The downward movement of the push rods 209 can also drive the two locking rods 207 to move downward inside the vertical groove 202. Under the inclined guidance of the self-locking groove 204, they can squeeze the sliding plate 203 to one side and squeeze the compression spring 206. At the same time, the two locking rods 207 will move downward inside the self-locking groove 204. When the two locking rods 207 reach the bottom of the inner wall of the self-locking groove 204, the sliding plate 203 will be pushed to slide in the opposite direction under the rebound of the compression spring 206, and the two locking rods 207 will be locked in the groove at the bottom of the inner wall of the self-locking groove 204. Thus, the two push rods 209 and the two window buttons can be locked by the locking rods 207. 211 is locked, preventing the operator from pressing or pulling the window button 211 upwards. This allows the window button 211 to be locked with a simple operation, improving vehicle safety and reliability. When the vehicle button needs to be unlocked, the unlock button 212 can be pressed downwards. Pressing the unlock button 212 downwards will push the push rod 209 and the sliding rod 208 downwards inside the vertical groove 202. Under the guidance of the unlock groove 205, the sliding plate 203 can be squeezed and moved to one side, squeezing the compression spring 206. When the sliding plate 203 moves to one side, the two self-locking grooves 204 can disengage from the two locking rods 207. Under the elastic force of the telescopic spring 210, the two push rods 209 and the locking rods 207 can slide upwards, and the two locking rods 207 can be moved to the top of the inner wall of the vertical groove 202, thus unlocking the two window buttons 211.
[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
