[0026] The present application will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without making creative changes are within the protection scope of the present application.

[0027] like Figures 1 to 7 As shown, the present invention provides a seat adjustment mechanism, including...

[0028] The guide rail 1 has a guide groove 12 and a plurality of limiting holes 13 provided on its surface along its length direction, and the limiting holes 13 are connected to the guide groove 12.

[0029] The sliding member 2 is provided with a sliding structure 7 and a locking structure 6. The sliding structure 7 is configured to slide within the guide groove 12, and its end dimension is larger than the dimension of the guide groove 12 and can disengage from the guide groove 12 through the limiting hole 13. The locking structure 6 is configured to cooperate with the limiting hole 13 to prevent the sliding member 2 from sliding on the guide rail 1. When the locking structure 6 cooperates with the limiting hole 13, the sliding structure 7 is misaligned with the limiting hole 13.

[0030] Unlocking structure 3 is configured to drive the locking structure 6 and the limiting hole 13 to disengage.

[0031] When installing the aforementioned seat adjustment mechanism inside a vehicle, first fix the guide rail 1 to the vehicle body, then assemble the sliding member 2 to the guide rail 1. The seat can be pre-installed on the sliding member 2, or the sliding member 2 can be assembled to the guide rail 1 before installing the seat. Figure 1 , 4As shown in Figure 5, when assembling the sliding member 2, simply insert the end of the sliding structure 7 into the guide groove 12 through the limiting hole 13. When the locking structure 6 engages with the limiting hole 13, the sliding member 2 is locked onto the guide rail 1 and cannot slide under the restriction of the limiting hole 13. Simultaneously, the sliding structure 7 is misaligned with the limiting hole 13 and will not disengage from the guide groove 12. Conversely, when it is necessary to remove the sliding member 2 from the guide rail 1, the locking structure 6 must be disengaged from the limiting hole 13, and then the end of the sliding structure 7 must be moved to align with the limiting hole 13 to separate the sliding member 2 from the guide rail 1. Figure 5 and 6 As shown, when the seat's fore-and-aft position needs to be adjusted, the locking structure 6 needs to be disengaged from the limiting hole 13. The sliding member 2 can then move back and forth on the guide rail 1. Due to the weight of the seat itself and the weight of the person sitting on it, even if the end of the sliding structure 7 is aligned with the limiting hole 13 during adjustment, the sliding structure 7 will not disengage from the limiting hole 13 unless the seat or the sliding member 2 is lifted upwards under external force. Therefore, the above solution is convenient to assemble and disassemble, and easy to operate, without requiring the sliding member 2 to slide in or out from one end of the guide rail 1.

[0032] like Figure 2 As shown, specifically, in one embodiment, the guide rail 1 has a U-shaped cross-section, with flanges 11 extending inward on both sides of its opening. The gap between the two flanges 11 forms the guide groove 12. Notches are provided on the flanges 11, forming the limiting hole 13. More specifically, notches are provided on both sides of the flanges 11 at the U-shaped opening. The notches are arc-shaped, and the positions of the notches on the two side flanges 11 correspond to each other, forming the limiting hole 13. This makes the flanges 11 form a tooth-like structure, and the size of the limiting hole 13 is larger than the width of the guide groove 12, making it easier to mold and manufacture. Two parallel guide rails 1 are provided at the bottom of the same seat, and the sliding member 2 is provided on both guide rails 1. Figure 4 As shown, the two sliding parts 2 can be connected together by a fixed beam 5 and / or a fixed rod 4 to improve stability.

[0033] like Figure 5 As shown, in one embodiment, the sliding structure 7 includes a fixed post 71. One end of the fixed post 71 is connected to the sliding member 2, and the other end passes through the guide groove 12 and is connected to the positioning block 72. The positioning block 72 is larger than the guide groove 12 and can disengage from the guide groove 12 through the limiting hole 13. The size of the positioning post matches the guide groove 12, and the size of the positioning block 72 can match the size of the limiting hole 13. Thus, when the positioning block 72 is at the bottom of the guide groove 12, it can only disengage from the limiting hole 13, and when it is misaligned with the limiting hole 13, it cannot disengage from the guide groove 12.

[0034] like Figure 4 and5 As shown, in some embodiments, the sliding member 2 is provided with the sliding structure 7 at least at both ends. For ease of installation, the sliding member 2 can be specifically configured to be made of a square tube, with mounting blocks 73 provided inside both ends. One end of the fixing post 71 passes through the sliding member 2 and is connected to the mounting block 73 inside it. The height of the mounting block 73 is consistent with the height of the internal cavity of the square tube, which can strengthen the structure of the sliding member 2 and facilitate the connection of the fixing post 71. In addition, to improve the stability of the sliding member 2, a guide member 74 can be installed on the outside of the sliding member 2 corresponding to the mounting block 73. The top of the guide member 74 is fixedly connected to the sliding member 2, and a sliding mating part with the same width as the guide groove 12 is provided on the side facing the guide rail 1. The fixing post 71 passes through the sliding mating part and is connected to the mounting block 73. Multiple mounting blocks 73 can be provided at one end of the sliding member 2, and multiple fixing posts 71 can be provided on one mounting block 73. Multiple fixing posts 71 can be installed on one guide member 74. The guide member 74 can not only improve the structural strength of the sliding member 2, but also play a role in guiding and stabilizing the fixing posts 71 during the sliding process, so as to prevent the sliding member 2 from tilting and shaking.

[0035] like Figure 4 and 5 As shown, in order to improve the smoothness of sliding, in one embodiment, the slider 2 is also provided with rollers 8 at both ends. Specifically, a retaining edge 14 can also be provided on the side of the flange 11 on both sides of the guide rail 1 away from the guide groove 12. The rollers 8 are supported on the flange 11, and their sides are restricted by the retaining edge 14 to prevent the rollers 8 from easily leaving the track.

[0036] like Figure 5As shown, in one embodiment, the locking structure 6 includes a limiting post 61 movably mounted on the sliding member 2, one end of which matches the shape of the limiting hole 13; a spring 63 is also provided between the limiting post 61 and the sliding member 2. Specifically, the size of the limiting post 61 is larger than the width of the guide groove 12 and slightly smaller than the size of the limiting hole 13, thus cooperating with the limiting hole 13 to play a limiting role, locking the sliding member 2, so that the limiting post 61 and the limiting hole 13 are tightly fitted, preventing the sliding member 2 from moving after the position is adjusted. The spring 63 can keep the limiting post 61 in a compressed state, preventing the limiting post 61 from disengaging from the limiting hole 13 due to bumps during vehicle operation. The sliding member 2 described above can be made of a square tube. The limiting post 61 passes through the square tube and is exposed on the outside of the sliding member 2 for easy connection with the unlocking structure 3. The other end extends through the sliding member 2 toward the guide rail 1. Since the wall thickness of the square tube is relatively thin, in order to prevent the end of the limiting post 61 extending toward the guide rail 1 from being pulled too far and retracting into the sliding member 2, a guide sleeve 62 can be provided in the through hole of the sliding member 2 through which the limiting post 61 passes, so as to extend the length of the through hole. At the same time, the guide sleeve 62 can also guide the limiting post 61.

[0037] In some embodiments, the unlocking structure 3 includes a rotating seat rotatably mounted on the sliding member 2 and an operating end for driving the rotating seat to rotate. The rotating seat is configured such that its rotation can disengage the locking structure 6 from the limiting hole 13. The operating end can be manual or electric. When electric, it is only necessary to connect a motor to the rotating seat to drive it to rotate, which is convenient to operate.

[0038] like Figure 1 , 4 As shown in Figures 6 and 7, specifically, in some embodiments, the operating end includes a connecting rod 31 and an operating lever 32. One end of the connecting rod 31 is connected to the rotating seat, and the other end is connected to the operating lever 32. The connecting rod 31 can be used to extend the lever arm of the rotating seat to the front end of the seat, thereby making the position of the operating lever 32 convenient for operation.

[0039] like Figure 3 and 7As shown, specifically, the rotating seat includes an operating plate 33 rotatably mounted on one side of the sliding member 2 and a mounting plate 34 located on top of the sliding member 2. The operating plate 33 and the mounting plate 34 are connected to form an L-shaped structure, and the locking structure 6 is connected to the mounting plate 34. The operating plate 33 is mounted on the sliding member 2 by a pin, and then rotates under the drive of the operating lever 32 and the connecting rod 31. Its rotation can drive the mounting plate 34 to rotate, and the rotation of the mounting plate 34 can drive the locking structure 6 to disengage from the limiting groove. Specifically, this can be achieved by the following structure: the mounting plate 34 can have a notch 36 at one end, and one end of the limiting post 61 of the locking structure 6 can be locked in the notch 36. At the same time, in order to make the rotation of the operating plate 33 smoother, an arc-shaped groove 35 can be provided on it. The fixing rod 4 connecting the two sliding members 2 on both sides of the seat passes through the arc-shaped groove 35, which not only serves to fix the two sliding members 2, but also serves to guide the rotation of the operating plate 33.

[0040] In addition, such as Figure 3 As shown, in order to further prevent the unlocking structure 3 from shaking during vehicle operation or from being misoperated, a limiting protrusion 37 can be provided at one end of the operating plate 33, and a limiting protrusion 21 can be provided on the sliding member 2. In the locked state, the limiting protrusion 37 and the limiting protrusion 21 are in contact and pressed together to prevent the unlocking structure 3 from shaking when bumping. When unlocking is required, the pressing force between the limiting protrusion 37 and the limiting protrusion 21 must be overcome first to separate the two before the unlocking operation can be performed, thus avoiding misoperation.

[0041] like Figure 4 and 5 As shown, in some embodiments, the sliding member 2 is further provided with a stabilizing structure 9. The stabilizing structure 9 includes a stabilizing rod 91 movably connected to the sliding member 2. One end of the stabilizing rod 91 passes through the guide groove 12 and is connected to a stabilizing block 92. The stabilizing block 92 is larger than the guide groove 12 and can disengage from the guide groove 12 through the limiting hole 13. The other end of the stabilizing rod 91 passes through the sliding member 2 and is movably connected to the mounting plate 34. A spring 63 is provided between the stabilizing rod 91 and the sliding member 2. When the limiting rod is located within the limiting hole 13, the stabilizing block 92 is misaligned with the limiting hole 13. A notch 36 can also be provided at the end of the mounting plate 34 away from the limiting post 61. The stabilizing rod 91 is connected to the mounting plate 34 through the notch 36, which can stabilize the unlocking structure 3 and prevent the unlocking structure 3 from shaking. At the same time, the spring 63 on the stabilizing rod 91 will also press the stabilizing rod 91 into the guide groove 12, which can prevent the stabilizing rod 91 from falling out of the guide groove 12. Similarly, the sliding member 2 can also be used to provide a guide sleeve 62 through the passage of the stabilizing rod 91.

[0042] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this application.
