DETAILED DESCRIPTION

[0025] The following is combined with Figures 1 to 6 This application is described in further detail.

[0026] The present application embodiment discloses a control box manual adjustment locking device for a vehicle seat, referring to Figure 1 , 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.

[0027] Reference Figures 2 to 4 In this embodiment, the two longitudinal side frames 1 of the adjustment frame are respectively installed with corresponding adjustment locking mechanisms; 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. The locking bracket 3 is inclined in the vertical direction and has an arc hole 6. The arc hole 6 is inclined in the direction away from the locking pin 5, and the center of the arc hole 6 is set in the direction away from the locking pin 5. The inclination angle of the arc hole 6 relative to the vertical direction of the locking bracket 3 is defined as α (0<α<90 degrees).

[0028] The locking plate 4 in the above-mentioned is provided with a mounting shaft 7 at the upper end portion in the vertical direction, one end of the mounting shaft 7 is penetrated through the arc hole 6 and is displaced relative to the arc hole 6, and one side edge of the locking plate 4 located at the lower side of the mounting shaft 7 is spaced apart with x locking grooves 8 adapted to the locking pin 5, wherein x≥2, the locking pin 5 is longitudinally arranged on the locking bracket 3 on one side of the locking plate 4, the end of the locking pin 5 can be top-mounted in the locking groove 8, and the distance between the locking pin 5 and the locking groove 8 is axially adjustable to achieve locking and unlocking of the locking groove 8. In the present embodiment, the locking pin 5 is threadedly matched with the locking bracket 3, and the locking pin 5 is rotated to make it move axially relative to the locking bracket 3 to achieve the effect of moving away from or approaching the locking groove 8, thereby achieving the effect of unlocking and locking. Of course, threaded matching with the locking bracket 3 is only one embodiment, and a constricted neck can also be provided on one side of the locking pin 5 near the locking groove 8, and an annular step surface is formed between the constricted neck and the locking pin 5, and a spring can be provided between the step surface and the locking bracket 3, and the spring always maintains the elastic force that pushes the locking pin 5 toward the direction of the locking groove 8.

[0029] When the locking pin 5 is in the locked position, the locking pin 5 is moved away from the locking groove 8 by rotating the locking pin 5 until the locking pin 5 is completely out of the locking groove 8. Then, under the action of external force, the locking plate 4 is rotated in the direction close to the locking pin 5 with the mounting shaft 7 as the center. Then, the mounting shaft 7 slides down in the arc hole 6 until it reaches the corresponding locking groove 8 position on the lower side. Then, the locking pin 5 is rotated in the opposite direction so that the locking pin 5 enters the locking groove 8 at the corresponding position for locking. Of course, in order to improve efficiency, the locking plate 4 can be rotated while the locking pin 5 is rotated.

[0030] In order to ensure that the locking pin 5 can enter the locking groove 8 at the corresponding position during adjustment, the center lines of the bottom of adjacent locking grooves 8 are all inclined in the direction away from the locking pin 5. At the same time, an isolation plate 9 is arranged between adjacent locking grooves 8. The longitudinal length of the isolation plate 9 decreases from top to bottom in the vertical direction of the locking plate 4, that is, the longitudinal length of the isolation plate 9 can be defined as L1, L2, L3, ... (L1>L2>L3...) from top to bottom; and the depth of the locking groove 8 increases from top to bottom in the vertical direction of the locking plate 4. After such a design, when the locking pin 5 enters the corresponding lock groove 8 from top to bottom or from bottom to top for gear adjustment, the blocking and limiting can be achieved by the difference in the longitudinal length of the isolation plate 9; in addition, in order to reduce the obstruction encountered by the locking pin 5 when it is inserted into the lock groove 8, the distance between the two opposite groove walls of the lock groove 8 also gradually increases toward the groove mouth of the lock groove 8.

[0031] Reference Figure 5In this embodiment, in order to improve the locking effect, y positioning protrusions 10 are provided on the lock plate 4. The positioning protrusion 10 is arranged on the side of the lock plate 4 opposite to the lock groove 8. A limiting hole 11 is arranged in the lateral direction of the lower side of the locking bracket 3. The lower end of the lock plate 4 is penetrated by the limiting hole 11. Under the action of the limiting hole 11, the lock plate 4 can only swing back and forth in the limiting hole 11. The swinging angle depends on the longitudinal width of the limiting hole 11. In this embodiment, if there are 3 lock grooves 8, there are 2 positioning protrusions 10, and when y≥2, all positioning protrusions 10 are arranged at intervals, and positioning grooves 12 for the edges of the limiting holes 11 to be inserted are formed between adjacent positioning protrusions 10; in addition, when the lock pin 5 is locked with the lock groove 8 corresponding to the position, a limit is formed between the positioning protrusion 10 and the corresponding side of the limiting hole 11.

[0032] In order to enable the positioning protrusion 10 to cooperate with the locking pin 5 to form a vertical position limiting function, the longitudinal length of the positioning protrusion 10 increases from top to bottom in the vertical direction of the lock plate 4. At the same time, the spacing between the two opposite side walls of the positioning protrusion 10 in the vertical direction gradually decreases in the direction away from the lock groove 8; that is, when the lock pin 5 and the lock groove 8 are unlocked, the lock pin 5 is rotated to gradually move away from the lock groove 8, and the lock plate 4 can be synchronously swung toward the lock pin 5. When the lock plate 4 swings to the maximum angle limited by the limiting hole 11 or close to the maximum angle , the limiting state of the side corresponding to the positioning protrusion 10 and the limiting hole 11 is released; when the locking pin 5 and the locking groove 8 are about to enter the locked state, the locking pin 5 is rotated to make the locking pin 5 gradually approach the bottom of the locking groove 8, and the locking plate 4 can be synchronously swung in the direction away from the locking pin 5. When the locking plate 4 swings to the maximum angle limited by the limiting hole 11 or close to the maximum angle, the limiting state of the side corresponding to the positioning protrusion 10 and the limiting hole 11 reaches the tight limit, and at the same time, the locking pin 5 is also locked with the locking groove 8. In this way, a double locking structure can be realized, which makes the locking reliability better.

[0033] Reference Figure 6 During the entire adjustment process, one side of the control box is rotated to the side away from the locking bracket 3, and the other side is installed on the mounting shaft 7. Therefore, when the control box realizes the change of the tilt angle, it rotates with the axis on the side away from the locking bracket 3 as the center.

[0034] 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.
