Detailed Implementation

[0032] This application is based on the inventor's discoveries and understanding of the following facts and problems:

[0033] In related technologies, such as the height adjustment mechanism of a vehicle seat, the seat height is maintained by the force balance between the cable and the resistance block. When the occupant turns the handle, the force balance between the cable and the resistance block is broken, causing the cable to tighten or loosen to adjust the seat height. However, the height adjustment is difficult to control. If the handle is turned too far, the seat will have too many positions, affecting the comfort during use.

[0034] Specifically, the adjustment mechanism in the related technology includes a turntable with external teeth. A cable surrounds a portion of the turntable's circumference and remains taut to provide a force for rotation in one direction. A resistance block abuts against the external teeth, and an elastic element maintains the pressure exerted by the resistance block on the external teeth, keeping the resistance block in contact with the root of the external teeth. At this time, the rotation of the turntable is restricted by the external teeth and is not rotated by the tension of the cable. When the occupant turns the handle, the resistance block overcomes the pressure of the elastic element and is gradually lifted by the tip of the external teeth, causing the turntable to rotate and achieving height adjustment.

[0035] However, when the occupant turns the handle, it is difficult to ensure that the rotation of the dial only causes the resistance block to cross the top of one external tooth, and it is easy to cross the top of multiple external teeth, resulting in the seat rising too high.

[0036] Furthermore, the adjustment height between each gear and the rotation angle of the handle can only be adjusted by changing the size of the turntable and the tooth spacing of the outer teeth, making it difficult to achieve more precise adjustments and inconvenient for passengers to use.

[0037] Moreover, the handle needs to be kept in the rotated position after rotation, and it is inconvenient for the passenger to operate again when the handle is rotated to some special angles, especially when the handle is usually arranged in a position that is not easy to observe, and the passenger needs to feel the handle position with hands, which further increases the difficulty of operation of the passenger.

[0038] In addition, the force required for the user to operate the handle to rotate cannot be adjusted, and the force of the elderly and children and other groups of people may be difficult to rotate the handle, which is not suitable for various groups of people,

[0039] The embodiments of the present application will be described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout.

[0041] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] The adjusting mechanism 1 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0043] As shown in Figures 1-11 The adjusting mechanism 1 according to the embodiments of the present application includes a mounting seat 100, a rotating shaft 200, a rotating disc 300 and an adjusting handle 400.

[0044] The mounting base 100 is mounted on a structure to be adjusted. The rotating shaft 200 is arranged on the mounting base 100. The rotating disc 300 is rotatably arranged on the rotating shaft 200. The adjusting handle 400 is rotatably arranged on the rotating shaft 200 between a first position and a second position, and the adjusting handle 400 has a reset position between the first position and the second position, and the adjusting handle 400 drives the rotating disc 300 to rotate in the same direction in a part of the process of rotating from the reset position to the first position, and drives the rotating disc 300 to rotate in the same direction in a part of the process of rotating from the reset position to the second position.

[0045] The skilled in the art can adjust the angle of the rotating disc 300 rotating in the part of the process according to actual needs, so as to control the degree of change of the structure to be adjusted after each rotation of the adjusting handle 400.

[0046] According to the adjusting mechanism 1 of the embodiment of the present application, the adjusting handle 400 drives the rotating disc 300 to rotate in the same direction in the part of the process of rotating from the reset position to the first position, and drives the rotating disc 300 to rotate in the same direction in the part of the process of rotating from the reset position to the second position, so that when the user rotates the adjusting handle 400, the adjusting handle 400 rotates from the reset position to the first position or from the reset position to the second position. No matter how large the angle of the adjusting handle 400 rotated by the user, the adjusting handle 400 can only drive the rotating disc 300 to rotate in the part of the process of rotating. Compared with the adjusting mechanism in the related art, the adjusting mechanism can avoid the user rotating the adjusting handle too large to cause the adjusting mechanism to cross multiple gears, causing the structure to be adjusted to cross multiple gears, for example, causing the seat to be raised too much to affect the comfort of the user when using. Thus, the adjusting mechanism 1 can be more finely and accurately adjusted, avoiding the discomfort caused by the user's misoperation, and improving the reliability of the adjustment.

[0047] Therefore, the adjusting mechanism 1 according to the embodiment of the present application has the advantages of fine and accurate adjustment, high reliability, etc.

[0048] The adjusting mechanism 1 according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0049] In some embodiments of the present application, as shown in Figures 1-11 The adjusting mechanism 1 according to the embodiment of the present application includes a mounting base 100, a rotating shaft 200, a rotating disc 300, and an adjusting handle 400.

[0050] Optionally, as shown in Figures 1-8As shown, the adjusting handle 400 has a first start position and a first stop position in the process of rotating from the reset position to the first position, and the rotating disc 300 rotates in the same direction in the process of rotating from the first start position to the first stop position. The adjusting handle 400 has a second start position and a second stop position in the process of rotating from the reset position to the second position, and the rotating disc 300 rotates in the same direction in the process of rotating from the second start position to the second stop position. In this way, the adjusting handle 400 needs to rotate a certain angle from the reset position before it can drive the rotating disc 300 to rotate synchronously, thereby avoiding accidental movement of the structure to be adjusted due to user misoperation.

[0051] Specifically, as shown in the figures, Figures 1-8 The adjusting mechanism 1 further comprises a conversion piece 500 and a sliding block 600. The conversion piece 500 is arranged on the rotating shaft 200 and connected with the adjusting handle 400 to rotate together with the adjusting handle 400. The sliding block 600 is arranged on the conversion piece 500 and can slide between an extended position and a retracted position. The rotating disc 300 is provided with an inner tooth 310. The sliding block 600 is engaged with the inner tooth 310 in the extended position and avoids the inner tooth 310 in the retracted position. The mounting seat is provided with a first stop protrusion 110 and a second stop protrusion 120. In the process of rotating from the first start position to the first stop position of the adjusting handle 400, the sliding block 600 is kept in the extended position by the first stop protrusion 110 (as shown by c→d in FIG. 6B). In the process of rotating from the second start position to the second stop position of the adjusting handle 400, the sliding block 600 is kept in the extended position by the second stop protrusion 120. Figure 8

[0052] Specifically, the sliding block 600 is provided with a sliding block protrusion 620. The sliding block 600 is adapted to cooperate with the first stop protrusion 110 and the second stop protrusion 120 through the sliding block protrusion 620. As shown in the figures, Figure 8 The process of rotating from the reset position to the first start position of the adjusting handle 400 is as shown by a→b→c in FIG. 6B. In this process, the sliding block protrusion 620 of the sliding block 600 abuts against the first stop protrusion 110, and the sliding block 600 is pushed to the extended position as shown by c in FIG. 6B under the pushing of the first stop protrusion 110. At this time, the sliding block 600 is engaged with the inner tooth 310 to enable the adjusting handle 400 to drive the rotating disc 300 to rotate together. Then the process of continuously rotating the adjusting handle 400 to the first stop position is as shown by c→d in FIG. 6B. In this process, the sliding block 600 is kept in the extended position by the first stop protrusion 110. As the adjusting handle 400 continues to rotate beyond the first stop position, Figure 8 Figure 8 Figure 8 Figure 8 ​​​​As shown in d→e, after the slider 600 passes the first stop protrusion 110, it loses the stop of the first stop protrusion 110 and is difficult to maintain in the extended position, allowing the turntable 300 and the adjusting handle 400 to rotate relative to each other, thus keeping the turntable 300 relatively stationary. The process of the adjusting handle 400 rotating from the reset position to the second position is the opposite in direction and the same in principle as the process of rotating from the reset position to the first position described above.

[0053] Therefore, the adjusting handle 400 and the turntable 300 can rotate synchronously only when the slider 600 is held in the extended position by the first stop protrusion 110 and the second stop protrusion 120, while the turntable 300 remains stationary during other processes. This allows the adjusting mechanism 1 to be adjusted only during the partial rotation of the adjusting handle 400, thus avoiding the adjusting mechanism 1 from crossing multiple gears and facilitating more precise and accurate adjustment.

[0054] Those skilled in the art will understand that by adjusting parameters such as the size of the first stop protrusion 110 and the second stop protrusion 120, the angle of the actual driving turntable 300 can be adjusted each time the adjustment handle 400 is rotated. Compared with the related technology, which can only control the degree of adjustment between gears by adjusting the size of the turntable 300 and the tooth pitch, the gear adjustment can be achieved in a more flexible way, making it easier to achieve more precise and accurate adjustment and more easily meeting the requirements of ergonomics.

[0055] Specifically, the conversion component 500 is provided with a sliding groove and a clearance groove communicating with the sliding groove. The slider 600 is slidably engaged in the sliding groove, and the sliding groove protrusion 620 is slidably engaged in the clearance groove. The slider protrusion 620 is adapted to pass through the clearance groove and engage with the first stop protrusion 110 or the second stop protrusion 120.

[0056] Furthermore, such as Figure 5 As shown, one of the conversion component 500 and the adjusting handle 400 is provided with a circumferential limiting shaft, and the other is provided with a circumferential limiting hole. The circumferential limiting shaft fits within the circumferential limiting hole and prevents relative rotation between the two. For example, the circumferential limiting shaft can be a square shaft and the circumferential limiting hole can be a square hole, or the circumferential limiting shaft can be a hexagonal shaft and the circumferential limiting hole can be a hexagonal hole.

[0057] Advantageously, such as Figures 1-8As shown, the slider 600 avoids the inner teeth 310 during the process that the adjustment handle 400 rotates from the first position to the reset position and during the process that the adjustment handle 400 rotates from the second position to the reset position. Specifically, the adjustment handle 400 drives the rotating disc 300 to rotate during a part of the process that the adjustment handle 400 rotates from the reset position to the first position or from the reset position to the second position, realizing the adjustment of the gear. Then, when the adjustment handle 400 rotates from the first position or the second position to the reset position, the slider 600 avoids the inner teeth 310 to keep the adjustment handle 400 and the rotating disc 300 from rotating relative to each other, keeping the rotating disc 300 static. In other words, when the adjustment handle 400 resets from the first position or the second position, the adjustment handle 400 does not drive the rotating disc 300 to rotate, and the gear of the adjustment mechanism 1 is not adjusted. In this way, the adjustment handle 400 can reset after the adjustment of the gear, which is convenient for the user to find the adjustment handle 400 again, avoids the problem that the adjustment handle 400 in the related art cannot reset, and makes it difficult for the user to adjust or even need to rely on hands to find, is convenient for the user to operate, and improves the comfort of the user in use.

[0058] More advantageously, as Figure 10 shown, the adjustment mechanism 1 further comprises a handle reset elastic member 410, which constantly drives the adjustment handle 400 to rotate to the reset position. Specifically, the handle reset elastic member 410 is a torsion spring and is sleeved on the rotating shaft 200, and the mounting seat 100 is provided with a torsion spring stop block 130 that stops the handle reset elastic member 410 from rotating circumferentially. In this way, the adjustment handle 400 can be driven to the reset position by the elastic force of the handle reset elastic member 410 after the user rotates the adjustment handle 400 from the reset position to the first position or the second position, and the adjustment handle 400 is reset by the elastic force of the handle reset elastic member 410, without the need for the user to manually reset, saving the process of manual reset by the user, and being convenient for the user to find the adjustment handle 400 again.

[0059] Further, as Figures 4-8 shown, the adjustment mechanism 1 further comprises a slider reset elastic member 610, which constantly drives the slider 600 to move to the retracted position. Specifically, the slider reset elastic member 610 is a tension spring and has two ends connected to the slider 600 and the mounting seat 100, respectively. In this way, the slider 600 can be kept in the retracted position, avoiding the slider 600 from moving to the extended position without being driven by the first stop protrusion 110 and the second stop protrusion 120, and ensuring that the rotating disc 300 is driven to rotate only when the adjustment handle 400 rotates from the first starting position to the first stop position and from the second starting position to the second stop position.

[0060] Still further, as Figure 8As shown, the first stop protrusion 110 and the second stop protrusion 120 are both arc-shaped plate and have convex and concave surfaces, the slider 600 contacts the concave surface of the first stop protrusion 110 in the process of rotating the adjusting handle 400 from the first initial position to the first stop position and contacts the convex surface of the first stop protrusion 110 in the process of rotating the adjusting handle 400 from the first stop position to the first initial position, the slider 600 contacts the concave surface of the second stop protrusion 120 in the process of rotating the adjusting handle 400 from the second initial position to the second stop position and contacts the convex surface of the second stop protrusion 120 in the process of rotating the adjusting handle 400 from the second stop position to the second initial position.

[0061] Specifically, the slider protrusion 620 of the slider 600 cooperates with the concave surface in the process of rotating the adjusting handle 400 from the initial position to the stop position, as shown by b→c→d in FIG. 6, so that the slider protrusion 620 cannot easily separate from the stop protrusion, and the stop protrusion can keep the slider 600 in the extended position. Figure 8 After the adjusting handle 400 is rotated to the first position or the second position, as shown by d→e in FIG. 6, the slider protrusion 620 separates from the first stop protrusion 110 or the second stop protrusion 120 and is retracted to the retracted position under the elastic action of the slider reset elastic member 610. Then the adjusting handle 400 starts to reset under the action of the handle reset elastic member 410, as shown by e→f→a in FIG. 6, the slider protrusion 620 cooperates with the convex surface of the stop protrusion, so that the slider 600 cannot be pushed to the extended position, and because the slider protrusion 620 cooperates with the convex surface, the slider protrusion 620 can smoothly pass through the stop protrusion, and the adjusting handle 400 can smoothly reset. Figure 8 Figure 8

[0062] Figures 1-8 The adjusting mechanism 1 according to some specific examples of the present application is shown. As shown in FIG. 1, the adjusting mechanism 1 comprises an adjusting handle 400, a slider 600 and a reset elastic member 410. Figures 1-8 ​​As shown, the adjusting mechanism 1 further comprises a cable 700 and a resistance block 800, one end of the cable 700 is connected with the rotating disc 300 and the other end of the cable 700 is connected with the structure to be adjusted through the mounting base 100, the cable 700 is kept tensioned around a part of the circumference of the rotating disc 300, the outer periphery of the rotating disc 300 is provided with external teeth 320, the resistance block 800 is slidably arranged on the mounting base 100 and abuts against the external teeth 320, the mounting base 100 is provided with a resistance elastic member 810 which drives the resistance block 800 to move towards the axis of the rotating disc 300. Specifically, when the rotating disc 300 rotates, the resistance elastic member 810 is used to lift the resistance block 800 by the external teeth 320 against the elastic force of the resistance elastic member 810. In this way, the rotating disc 300 is driven to rotate by the cable 700, the rotation of the rotating disc 300 is prevented by the cooperation of the resistance block 800 and the external teeth 320, and the resistance block 800 is provided with the force to abut against the external teeth 320 by the elastic force of the resistance elastic member 810.

[0063] Specifically, the cable 700 can be connected with the structure to be adjusted by a tensioning elastic member, so as to keep the cable 700 tensioned. For example, when applied to the height adjustment of a seat, the tension provided by the cable 700 can be used to overcome the weight of the seat and the occupant to lift the seat.

[0064] Advantageously, as Figure 9 As shown, the resistance elastic member 810 is a compression spring and one end of the resistance elastic member 810 abuts against the resistance block 800 and the other end of the resistance elastic member 810 abuts against an adjusting bolt 820 which is threadedly engaged with the mounting base 100. In this way, the force applied by the resistance elastic member 810 on the resistance block 800 can be adjusted by tightening or loosening the adjusting bolt 820, so as to adjust the force required for the rotating disc 300 to rotate, thereby adjusting the force required for the adjusting handle 400 to rotate, which facilitates the use of different user groups such as the elderly and children, and improves the applicability of the adjusting mechanism 1.

[0065] Specifically, the adjusting mechanism 1 is a seat height adjusting mechanism. For example, the adjusting mechanism 1 is arranged at the hinge of a scissor lifting arm of a seat, and the rotation of the rotating disc 300 drives one of the lifting arms to rotate relative to the other, thereby adjusting the height of the seat. It can be understood by those skilled in the art that the seat lifting structure and operation are well known to those skilled in the art.

[0066] Specifically, the mounting base 100, the rotating disc 300, the adjusting handle 400 and the conversion member 500 are all penetrated by the rotating shaft 200, so as to connect the mounting base 100, the rotating disc 300, the adjusting handle 400 and the conversion member 500 by the rotating shaft 200. The two ends of the rotating shaft 200 are respectively provided with thrust pieces 900 to prevent the structures on the rotating shaft 200 from moving along the axial direction of the rotating shaft 200.

[0067] Specifically, one of the mounting base 100 and the conversion piece 500 is provided with the rotation limiting boss 140 and the other is provided with the rotation limiting groove 510, here preferably the rotation limiting groove is provided on the conversion piece 500 and the rotation limiting boss 140 is provided on the mounting base 100. The rotation limiting boss 140 is rotatably matched in the rotation limiting groove 510, the rotation limiting groove 510 is an open loop groove, the rotation limiting boss 140 is an open loop boss, and the length of the rotation limiting boss 140 is less than the length of the rotation limiting groove 510. One end of the rotation limiting boss 140 abuts against the rotation limiting groove 510 when the adjusting handle 400 is in the first position and the other end of the rotation limiting boss 140 abuts against the rotation limiting groove 510 when the adjusting handle 400 is in the second position. In this way, the maximum rotation angle of the adjusting handle 400 can be conveniently limited, and the normal operation of the adjusting mechanism 1 is avoided from being affected by the rotation of the adjusting handle 400 for one round.

[0068] The adjusting mechanism 1 according to the embodiment of the present application, when the adjusting handle 400 is rotated from the reset position to the reset position again, only drives the rotating disc 300 to rotate synchronously in the process from the first starting position to the first stopping position and from the second starting position to the second stopping position. On the one hand, the degree of actual adjustment of the structure to be adjusted after each rotation of the adjusting handle 400 can be controlled, and over-adjustment is avoided, so that more accurate adjustment is achieved. On the other hand, the adjusting handle 400 can be returned to the reset position, which is convenient for the user to find again. By setting the adjusting bolt 820, the rotation force required by the adjusting handle 400 can be controlled, and the applicability is improved.
