Description

Technical Field

[0001] This application relates to the field of automotive seat rails, and more particularly to an automotive seat rail with integrated front and rear damping. Background Technology

[0002] With the development of construction machinery vehicles, the requirements for driver and passenger comfort are also increasing. Most of the existing vehicle seat vibration damping mechanisms are Z-direction (vertical direction) damping, which can absorb the impact in the Z direction, while the X-direction (front and rear direction) often has no damping. In order to meet the needs of ride comfort, in recent years, various companies have successively developed front and rear vibration damping mechanisms.

[0003] Currently, most traditional front and rear damping mechanisms are independent. However, independent front and rear damping is an independent module of the seat, which increases the number of SIP points on the seat. For seats with low SIP requirements, using independent front and rear damping mechanisms cannot meet the requirements and standards of such low-sitting-position seats.

[0004] Therefore, the inventors believe that achieving both a low-sitting-position seat and front-to-back vibration reduction is a technical problem that urgently needs to be solved. Summary of the Invention

Detailed Implementation

[0024] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0025] This application discloses an automotive seat slide rail with integrated front and rear vibration damping. (See also...) Figure 1 , 2 It includes a sliding upper rail and a sliding lower rail. The upper rail includes a main body 1 in the shape of a gate. The upper rail has an outward flange 2 and an upward flange 3 arranged sequentially on the lower ends of the two sides of the main body 1. The lower rail includes a main body 4 in the shape of an inverted gate. The lower rail has an inward flange 5 and a downward flange 6 arranged sequentially on the upper ends of the two sides of the main body 4. The upward flange 3 on both sides is located inside the downward flange 6 on the corresponding side.

[0026] Reference Figures 3 to 5The lower rail is provided with a front and rear vibration damping mechanism installed between the upper and lower rails. The front and rear vibration damping mechanism includes an adjustment component, a locking component, and a vibration damping component. The locking component and the vibration damping component are both set on the adjustment component. The vibration damping component is provided with front and rear sections, and the locking component is set between the two sections of the vibration damping component.

[0027] In this embodiment, the adjustment assembly includes a front adjustment bracket 7 disposed on the front side of the lower rail, a rear adjustment bracket 8 disposed on the rear side of the lower rail, and an adjustment rod 9. The adjustment rod 9 passes through the front adjustment bracket 7 and the rear adjustment bracket 8 and can rotate relative to the front adjustment bracket 7 and the rear adjustment bracket 8. The front adjustment bracket 7 and the rear adjustment bracket 8 are provided with an extension plate 10 on their lower sides facing the lower rail. The extension plate 10 extends to the lower end surface of the lower rail and forms a fixed relationship with the lower rail. The adjustment rod 9 passes through the front adjustment bracket 7 and the rear adjustment bracket 8 sequentially from the front side. An adjustment handle 11 can be installed at the front end of the adjustment rod 9 for easy manual operation.

[0028] The locking assembly described above is located on the adjusting rod 9 between the front adjusting bracket 7 and the rear adjusting bracket 8. The locking assembly includes a front partition 12, a vibration damping locking member 13, a slide rail locking member 14, and a rear partition 15, arranged sequentially from front to back on the adjusting rod 9. The vibration damping locking member 13 is fixedly sleeved on the adjusting rod 9, and the slide rail locking member 14 is rotatably sleeved on the adjusting rod 9. The front partition 12 and the rear partition 15 are stationary relative to the adjusting rod 9. This relative stationary state is achieved through the following structure: the front partition... Both the upper and lower sides of the baffle 12 and the rear baffle 15 are provided with extension plates 10 facing the lower rail. The extension plates 10 on the upper side extend to the upper end face of the lower rail. Under normal circumstances, it is not recommended to extend to the upper end face of the upper rail. The extension plates 10 on the lower side extend to the lower end face of the lower rail. The extension plates 10 on the upper and lower sides form a limit with the lower rail. No matter how the adjusting rod 9 rotates, the front baffle 12 and the rear baffle 15 remain stationary relative to the adjusting rod 9 due to this limit relationship.

[0029] In order to create a tactile feedback between the vibration damping locking component 13 and the front partition 12 during adjustment and to facilitate the subsequent locking operation of the vibration damping locking component 13, a locking pin 16 can be provided on the side of the vibration damping locking component 13 near the front partition 12. The front partition 12 is provided with a locking protrusion 17 in the shape of a trapezoid, triangle or semicircle. The locking pin 16 can slide along the edge of the locking protrusion 17 as the vibration damping locking component 13 rotates. When the locking pin 16 is displaced to either side of the locking protrusion 17, it forms two different states of unlocking and locking.

[0030] In this embodiment, the area corresponding to the lower rail and the vibration damping locking member 13 and the slide rail locking member 14 is provided with a locking notch. The vibration damping locking member 13 is provided with a limiting block 18 facing the lower rail. The lower rail is provided with a locking plate 19 at the locking notch. The locking plate 19 is provided with a limiting slot 20 for the limiting block 18 to be engaged or disengaged. In typical design, the locking plate 19 can be provided with a notch 21 that matches the position of the locking notch, and the limiting slot 20 is provided at the bottom of the notch 21. When the locking pin 16 rotates away from the lower rail, the locking pin 16 rotates to the other side of the locking protrusion 17 and forms a locking state. At this time, the limiting block 18 is engaged in the limiting slot 20. Conversely, it forms an unlocked state.

[0031] Additionally, a limiting pin 22 is provided on the side of the vibration damping locking member 13 facing the slide rail locking member 14. A limiting groove 23 is provided axially on the side wall corresponding to the position of the limiting pin 22 on the slide rail locking member 14. The limiting pin 22 can radially swing within the limiting groove 23 as the vibration damping locking member 13 rotates. When the limiting pin 22 rotates away from the lower rail, it reaches the side of the limiting groove 23 away from the lower rail, at which point it is in a locked state. In this embodiment, to achieve the slide rail locking state, a locking block 24 can be provided on the side of the slide rail locking member 14 facing the lower rail, with the upper flange 3 fitting the locking notch. Multiple locking grooves 25 are provided at intervals to fit the locking block 24. The locking grooves 25 allow the locking block 24 to be engaged or disengaged. When the limiting pin 22 and the limiting groove 23 are locked, the vibration damping locking member 13 can continue to rotate away from the lower rail with the adjusting rod 9. During further rotation, since the limiting pin 22 and the limiting groove 23 are locked, the limiting pin 22 will exert a force on the slide rail locking member 14 to rotate away from the lower rail, thereby causing the locking block 24 to engage in the locking groove 25. When the limiting pin 22 rotates in the opposite direction, the locking block 24 can be disengaged from the locking groove 25.

[0032] In this embodiment, the front damping component is disposed between the front adjusting bracket 7 and the locking component, and the rear damping component is disposed between the rear adjusting bracket 8 and the locking component. The damping component includes two springs 26, a front spring 26 located between the front adjusting bracket 7 and the front partition 12, and a rear spring 26 located between the rear adjusting bracket 8 and the rear partition 15. A rear mounting bracket 27 is disposed on the rear side of the rear adjusting bracket 8, and a damping rod 28 is mounted on the mounting bracket. The top end of the damping rod 28 is fixedly mounted on the front mounting bracket 29, and the front mounting bracket 29 is fixedly mounted between the rear spring 26 and the rear partition 15.

[0033] In this embodiment, the front and rear vibration damping mechanisms mainly exhibit three working states:

[0034] 1. Locked state: The entire structure is in a fully locked state due to the locking between the locking groove 25 and the locking block 24, as well as the locking between the limiting block 18 and the limiting slot 20. At this time, the forward and backward sliding between the upper and lower rails is in a locked state, and the forward and backward vibration damping effect is also in a locked state.

[0035] 2. Vibration damping state, which can also be understood as a semi-unlocked state, means that when the adjusting rod 9 is rotated in the direction of the lower rail, the vibration damping locking component 13 is rotated, causing the limiting pin 22 to rotate synchronously in the direction of the lower rail, so that it rotates to the side of the limiting groove 23 close to the direction of the lower rail. At this time, the locking groove 25 and the locking block 24 remain locked, while the limiting block 18 and the limiting slot 20 are disengaged to achieve unlocking, so that the entire structure is in a semi-locked state. At this time, the forward and backward sliding between the upper rail and the lower rail is in a locked state, and the forward and backward vibration damping can play a vibration damping role and absorb the impact in the X direction.

[0036] 3. Unlocked state, which can also be understood as the slide rail adjustment state, at which time the slide rail can be adjusted forward and backward.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
