DETAILED DESCRIPTION
[0017] The following is combined with Figure 1 , 2 This application is described in further detail.
[0018] Reference Figure 1 , 2 The slide rail of the seat includes an upper rail 1 and a lower rail 2, and the upper rail 1 and the lower rail 2 can slide relative to each other. The upper rail 1 is provided with a slide rail unlocking component 3 for controlling the upper rail 1 and the lower rail 2 to be in a stationary state or a sliding state.
[0019] The present application embodiment discloses a manual unlocking mechanism for a seat rail. Figure 2 , including a left unlocking slide 4 and a right unlocking slide 5 which are arranged between the left and right slide rails and are respectively located on the left and right sides. The left end of the left unlocking slide 4 is a left hinged end 6 connected to the left slide rail unlocking component 3, and the right end of the right unlocking slide 5 is a right hinged end 7 connected to the right slide rail unlocking component 3.
[0020] In this embodiment, a rear unlocking component is arranged at the right end portion of the left unlocking slide 4 and the middle portion of the right unlocking slide 5, and the rear unlocking component includes a right limiting substrate 8 and a right strip-shaped unlocking slide hole 9, wherein the right limiting substrate 8 is located at the right end portion of the left unlocking slide 4 and is bent toward the rear side, and the right strip-shaped unlocking slide hole 9 is arranged in the middle portion of the right unlocking slide 5. In order to ensure that the rear unlocking component can work more smoothly, a right connecting piece 10 can be arranged at the middle portion of the right unlocking slide 5 tilted toward the rear side, and the right strip-shaped unlocking slide hole 9 is arranged between the right connecting piece 10 and the right end portion of the right unlocking slide 5.
[0021] The rear unlocking assembly is used in the following way: unlocking is achieved by connecting the right limit base plate 8 and the right strip unlocking slide hole 9 through the unlocking pull wire set at the rear side, wherein the unlocking pull wire includes a steel wire rope and a protective tube, the protective tube is sleeved on the steel wire rope, and the two ends of the steel wire rope are respectively exposed outside the corresponding ends of the protective tube, one end of the protective tube is installed on the right limit base plate 8, and the end of the steel wire rope exposed at the end of the protective tube is installed with a sliding pin, and the sliding pin and the right strip unlocking slide hole 9 are adapted to be installed. When unlocking is required, the other end of the steel wire rope is pulled to shorten the steel wire rope between the sliding pin and the right limit base plate 8, thereby pulling the left unlocking slide 4 and the right unlocking slide 5 closer to each other, so that the left hinged end 6 of the left unlocking slide 4 and the right end of the right unlocking slide 5 synchronously pull the corresponding left slide rail unlocking assembly 3 and the right slide rail unlocking assembly 3 to unlock.
[0022] Similarly, a front unlocking component is provided at the left end of the right unlocking slide 5 and the middle of the left unlocking slide 4. The structure and working principle of the front unlocking component are similar to those of the rear unlocking component. The front unlocking component includes a left limiting substrate 11 and a left strip-shaped unlocking slide hole 12. The left limiting substrate 11 is located at the left end of the right unlocking slide 5 and is bent toward the rear side. The left strip-shaped unlocking slide hole 12 is arranged in the middle of the left unlocking slide 4. A left connecting piece 13 is arranged at the middle of the left unlocking slide 4 inclined toward the rear side. The left strip-shaped unlocking slide hole 12 is arranged between the left connecting piece 13 and the right end of the left unlocking slide 4.
[0023] In this embodiment, the right side portion of the left unlocking slide 4 and the left side portion of the right unlocking slide 5 are arranged to overlap, and a reset component is arranged between the overlapping left unlocking slide 4 and the right unlocking slide 5, and the reset component includes a left bracket 14, a right bracket 15, and a reset spring 16. The left bracket 14 is located on the upper side or the lower side of the overlapping left unlocking slide 4 and is close to the rightmost side of the overlapping left unlocking slide 4. The right bracket 15 is located on the upper side or the lower side of the overlapping right unlocking slide 5 and is close to the leftmost side of the overlapping right unlocking slide 5. The reset spring 16 is installed between the left bracket 14 and the right bracket 15 on the same side.
[0024] In order to ensure that there is no swing or shaking that affects the unlocking action when the left unlocking slide 4 and the right unlocking slide 5 are close to or away from each other, and to make the matching structure between the two more stable, a left mounting hole 17 and a left guide bar sliding hole 18 can be arranged at intervals on the overlapping left unlocking slide 4, and a right mounting hole 19 and a right guide bar sliding hole 20 can be arranged at intervals on the overlapping right unlocking slide 5, wherein the left mounting hole 17 is adapted to the position of the right guide bar sliding hole 20, and the right mounting hole 19 is adapted to the position of the left guide bar sliding hole 18, a left guide pin 21 slidably matched with the right guide bar sliding hole 20 is penetrated through the left mounting hole 17, and a right guide pin 22 slidably matched with the left guide bar sliding hole 18 is penetrated through the right mounting hole 19.
[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
