Description

Technical Field

[0001] This application relates to the field of automotive seat components technology, and more specifically, to a manual slide rail for automotive seats. Background Technology

[0002] Car seat rails are one of the core components of car seats, used to adjust the seat's fore-and-aft position, directly affecting driving comfort and safety.

[0003] Existing technology CN209616945U discloses a locking slide rail, including an upper rail and a lower rail that are slidably connected. A groove is formed on the side of the lower rail near the upper rail along its length. A toothed plate is slidably disposed within the groove. Multiple toothed blocks are provided on both sides of the toothed plate. A rack is fixed on both sides of the groove opening, engaging with the toothed blocks. A connecting block is fixed on the upper rail. An elastic pin is elastically disposed within the connecting block along the depth of the groove. The elastic pin is fixed to the toothed plate. In use, the elastic pin drives the toothed plate to engage with the toothed groove of the rack, fixing and locking the upper and lower rails in their respective positions. When it is necessary to slide the upper rail to change the seat's position in the carriage, the elastic pin is pressed down, causing the toothed plate to move towards the bottom of the groove, disengaging from the rack's toothed groove. The upper rail can then slide along the length of the lower rail to adjust the seat position.

[0004] However, in the existing technology CN209616945U, the upper rail slides directly on the lower rail, and the sliding force of the upper rail is not very good, which leads to increased wear of the components and affects their durability and service life. Utility Model Content

[0005] The purpose of this application is to provide a manual slide rail for automobile seats, which optimizes the sliding force of the slide rail, improves the durability of the slide rail, and extends the service life of the slide rail.

[0006] This application provides a manual slide rail for a car seat, employing the following technical solution:

[0007] A manual slide rail for a car seat includes two sets of slide rail structures arranged in parallel and an unlocking component disposed between the two sets of slide rail structures. The slide rail structure includes an upper slide rail and a lower slide rail that are slidably assembled, and a locking component for locking the upper slide rail and the lower slide rail. A retainer is provided at both ends of the lower slide rail. The upper slide rail is slidably connected to the retainer. A roller is provided at both ends of the retainer. The roller contacts the upper slide rail.

[0008] Preferably, the cage has balls at both ends, the balls are located above the rollers, and the balls are in contact with the upper slide rail.

[0009] Preferably, oil reservoirs are provided at both ends of the cage, and the oil reservoirs are located on the side of the ball bearing and above the end of the upper slide rail.

[0010] Preferably, the oil storage tank has a spherical structure.

[0011] Preferably, a movable piece is provided at the lower end of the upper slide rail, and a first limiting piece and a second limiting piece are provided on the lower slide rail, with the movable piece located between the first limiting piece and the second limiting piece.

[0012] Preferably, the unlocking assembly includes two parallel support members, a handle disposed between the two support members, and unlocking members disposed at both ends of the handle. The support members are disposed on the upper slide rail, and the upper end of at least one of the support members is bent to form a blocking plate. The unlocking member is used to press the positioning pin of the locking assembly, and the blocking plate is used to limit the unlocking member. A torsion spring is disposed between the support member and the handle.

[0013] Preferably, the unlocking assembly further includes a rotating bushing disposed on the support member, and the end of the handle is disposed on the rotating bushing.

[0014] Preferably, the unlocking component includes a rotating plate and an unlocking rod, the rotating plate is disposed on the handle, the unlocking rod is disposed on the rotating plate, and the support member is provided with a through groove for the unlocking rod to pass through.

[0015] Preferably, one end of the torsion spring is bent and secured to the support member, and the other end of the torsion spring is bent and secured to the rotating plate.

[0016] Preferably, the blocking plate is provided with a sound-absorbing pad.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] This application provides retainers at both ends of the lower slide rail to support the upper slide rail.

[0039] Example

[0040] like Figure 1-12 As shown in the embodiment of this application, the manual slide rail for a car seat includes two sets of slide rail structures 1 arranged in parallel and an unlocking component 2 disposed between the two sets of slide rail structures 1. The slide rail structure 1 includes an upper slide rail 3 and a lower slide rail 4 that are slidably assembled, and a locking component 5 for locking the upper slide rail 3 and the lower slide rail 4. The lower slide rail 4 has retainers 6 disposed at both ends. The upper slide rail 3 is slidably connected to the retainers 6. The retainers 6 has rollers 7 disposed at both ends. The rollers 7 are coated with grease and are in contact with the upper slide rail 3. In a specific implementation, each retainer 6 is provided with four rollers 7, and two rollers 7 are disposed at each end of the retainer 6.

[0041] When adjusting the position of the car seat, first use the unlocking component 2 to unlock the upper slide rail 3 and the lower slide rail 4, then slide the upper slide rail 3. The sliding of the upper slide rail 3 causes the roller 7 to rotate synchronously, thereby reducing the frictional resistance encountered by the upper slide rail 3 when sliding. The grease setting can ensure the rotation effect of the roller 7, further reducing the frictional resistance encountered by the upper slide rail 3, optimizing the sliding force of the slide rail, improving the durability of the slide rail, and extending the service life of the slide rail. After the car seat position adjustment is completed, use the locking component 5 to lock the upper slide rail 3 and the lower slide rail 4.

[0042] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in this embodiment, ball bearings 8 are respectively provided at both ends of the cage 6. In specific implementation, four ball bearings 8 are provided on each cage 6, and two ball bearings 8 are provided at each end of the cage 6. The ball bearings 8 are located above the rollers 7 and are in contact with the upper slide rail 3. The ball bearings 8 are coated with grease to ensure the rotation effect of the ball bearings 8. When the upper slide rail 3 slides, the ball bearings 8 rotate synchronously. The ball bearings 8 and the rollers 7 work together to ensure the stability of the upper slide rail 3 and avoid jamming problems.

[0043] Since the amount of grease applied to rollers 7 and balls 8 is limited, in order to further optimize the sliding force of the slide rail, such as... Figure 4 , Figure 5 and 7 As shown, in this embodiment, oil reservoirs 9 are provided at both ends of the retainer 6. The oil reservoirs 9 are located on the side of the ball 8 and above the end of the upper slide rail 3. The oil reservoirs 9 are used to provide grease between the ball 8 and the upper slide rail 3. When the upper slide rail 3 moves back and forth or the vehicle is driving on the road, the grease can be lubricated by vibration and friction.

[0044] like Figure 7As shown, in this embodiment, the oil storage tank 9 has a spherical structure and is filled with grease. The spherical structure of the oil storage tank 9 can easily retain some grease in its arc-shaped area, slowing down the outflow speed of the grease, thereby further improving the durability of the slide rail.

[0045] Currently, the forward and backward travel of manual slide rails on the market is constrained by a metal pin mounted on a bracket within the slide rail, along with front and rear limit plates. To optimize the process and reduce production costs, such as... Figure 1 , Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, in this embodiment, a movable piece 10 is provided at the lower end of the upper slide rail 3, and a first limiting piece 11 and a second limiting piece 12 are provided on the lower slide rail 4. The movable piece 10 is located between the first limiting piece 11 and the second limiting piece 12. When the upper slide rail 3 moves, the first limiting piece 11 and the second limiting piece 12 limit the movable piece 10, thereby limiting the stroke of the upper slide rail 3.

[0046] like Figure 1-5 , Figure 11-12 As shown, in this embodiment, the unlocking component 2 includes two parallel support members 13, a handle 14 disposed between the two support members 13, and unlocking members 15 disposed at both ends of the handle 14. The support members 13 are disposed on the upper slide rail 3, and the upper end of at least one support member 13 is bent to form a blocking plate 16. The unlocking member 15 is used to press the elastic pin 24 of the locking component 5, and the blocking plate 16 is used to limit the unlocking member 15. A torsion spring 17 is disposed between the support member 13 and the handle 14.

[0047] When unlocking, gently lift the handle 14. The handle 14 drives the unlocking component 15 to rotate, causing the unlocking component 15 to press the elastic pin 24 of the locking assembly 5. The elastic pin 24 drives the locking piece 25 to move down, and the locking piece 25 separates from the limiting groove 26, realizing the unlocking function. At this time, the torsion spring 17 is compressed and the spring 27 in the mounting base 23 is stretched. After the car seat adjustment is completed, release the handle 14. Under the action of the rebound force of the torsion spring 17, the handle 14 returns to its original position. Under the action of the rebound force of the spring 27, the elastic pin 24 of the locking assembly 5 returns to its original position, and the locking piece 25 and the limiting groove 26 return to their initial state, realizing the locking of the upper slide rail 3 and the lower slide rail 4. The unlocking and locking of the locking assembly 5 are existing technologies and will not be described in detail here.

[0048] like Figure 1-5 As shown, in this embodiment, the unlocking component 2 also includes a rotating bushing 18 disposed on the support member 13, and the end of the handle 14 is disposed on the rotating bushing 18. The rotating bushing 18 can improve the safety and reliability of use.

[0049] like Figure 1-5As shown, in this embodiment, the unlocking component 15 includes a rotating plate 19 and an unlocking rod 20. The rotating plate 19 is disposed on the handle 14, and the unlocking rod 20 is disposed on the rotating plate 19. The support component 13 is provided with a through groove 21 for the unlocking rod 20 to pass through. The above structure can make the overall layout more compact and reduce the space occupied.

[0050] like Figure 1-5 and Figure 8 As shown, in this embodiment, one end of the torsion spring 17 is bent and locked onto the support member 13, and the other end of the torsion spring 17 is bent and locked onto the rotating plate 19. The above structure design can improve the stability of the torsion spring 17.

[0051] like Figure 1-5 As shown in this embodiment, a noise-absorbing pad 22 is provided on the blocking plate 16. When the handle 14 is lifted, the rotating plate 19 collides with the noise-absorbing pad 22 to avoid generating noise.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
