DETAILED DESCRIPTION

[0020] The following is combined with Figures 1 to 3 This application is described in further detail.

[0021] The present application embodiment discloses a control box adjustment locking device for a vehicle seat, referring to Figure 1 , 2 , including an adjustment frame, the adjustment frame includes at least two longitudinal side frames 1 arranged vertically and two transverse side frames 2 arranged horizontally, and the two longitudinal side frames 1 and the transverse side frames 2 form a frame structure of a frame type structure.

[0022] In this embodiment, adjustment locking mechanisms are respectively installed on the two longitudinal side frames 1 of the adjustment frame, and the positions of the two adjustment locking mechanisms correspond to each other; the adjustment locking mechanism includes a locking bracket 3, a locking plate 4 and a locking pin 5. The locking bracket 3 is an L-shaped bracket in this embodiment. A strip hole 6 is obliquely arranged on the locking bracket 3. The inclination angle of the strip hole 6 relative to the vertical direction of the locking bracket 3 is defined as α (0<α<90 degrees). A mounting shaft 7 is provided at the upper end of the locking plate 4 in the vertical direction. One end of the mounting shaft 7 is penetrated through the strip hole 6 and can be displaced relative to the strip hole 6. At least two locking grooves 8 adapted to the locking pin 5 are spaced apart on one side edge of the locking plate 4 located at the lower side of the mounting shaft 7. The locking pin 5 is arranged on the locking bracket 3 at the lower side of the strip hole 6.

[0023] In order to ensure that the lock plate 4 always has a traction force approaching the lock pin 5, tension springs 9 are respectively installed on the two longitudinal side frames 1 of the adjustment frame, one end of the tension spring 9 is connected to the lower end of the corresponding side lock plate 4 in the vertical direction, and the other end is installed on the corresponding side longitudinal side frame 1 at a position away from the lock plate 4, and the lock pin 5 is located in the area between the lock plate 4 and the tension spring 9. At the same time, the tension spring 9 needs to always maintain the traction force pulling the lock plate 4 toward the lock pin 5. In this embodiment, the other end of the tension spring 9 is installed on the tension spring bracket 10 on the corresponding side longitudinal side frame 1. In actual applications, the installation position and method of the other end of the tension spring 9 can be set according to actual needs, such as providing a hook structure for installing the other end of the tension spring 9 on the corresponding side longitudinal side frame 1.

[0024] When the locking pin 5 is in the locked state, the locking plate 4 is rotated around the mounting shaft 7 and the locking plate 4 is moved downwards to the locking groove 8. When the locking pin 5 is in the locked state, the locking plate 4 is rotated around the mounting shaft 7 and the locking plate 4 is moved downwards to the locking groove 8. When the locking pin 5 is in the locked state, the locking plate 4 is rotated around the mounting shaft 7 and the locking plate 4 is moved downwards to the locking groove 8.

[0025] In this embodiment, refer to Figure 3 In order to ensure that the lock pin 5 can enter the lock groove 8 step by step, the center lines of the bottom of adjacent lock grooves 8 are all inclined toward the direction of the tension spring 9, and an isolation plate 11 is arranged between adjacent lock grooves 8. The length of the isolation plate 11 in the longitudinal direction increases from top to bottom in the vertical direction of the lock plate 4, that is, the length of the isolation plate 11 in the longitudinal direction can be defined as L1, L2, L3, ... (L1 < L2 < L3 ...) from top to bottom; at the same time, the depth of the lock groove 8 decreases from top to bottom in the vertical direction of the lock plate 4. After such a design, when the lock pin 5 enters the lock groove 8 step by step from top to bottom, the blocking limit can be achieved by the difference in the longitudinal length of the isolation plate 11. At the same time, the center lines of the bottom of adjacent lock grooves 8 and the depth of the lock groove 8 decrease step by step from top to bottom, which improves the locking pin 5. Downward, the speed of inserting into the lock groove 8 will be faster. At the same time, it also ensures that when the lock pin 5 is inserted into the lock groove 8 step by step, the difficulty of inserting is also significantly reduced, and it can be ensured that when the lock pin 5 is inserted into the corresponding lock groove 8 upward, it can also be inserted into the corresponding lock groove 8 across levels. In addition, in order to reduce the obstruction encountered by the lock pin 5 when it is inserted into the lock groove 8, the distance between the two opposite groove walls of the lock groove 8 can be gradually increased toward the notch of the lock groove 8, which can quickly guide the lock pin 5 to insert. During this whole process, one side of the control box 13 can be rotatably set on the axis with the tension spring bracket 10, and the other side is installed on the installation shaft 7. Therefore, in the process of realizing the change of the tilt angle, the control box 13 rotates with the axis of the tension spring bracket 10 as the center.

[0026] 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.
