Description

Technical Field

[0001] This utility model relates to the field of slide rail structures, and in particular to a seat slide rail structure. Background Technology

[0002] When existing caravan or bus seats meet the strength requirements of GB15083 M1 class, the slide rails do not allow for long-stroke seat movement, or the slide rails are not compatible with the vehicle body when they do allow for long-stroke seat movement. That is, the slide rails matched with the seats have a short stroke, generally less than 500mm. The existing slide rail strength can only support single or double seats. They mostly use rubber dustproof pads to protect against foreign objects, but lack foreign object protection structures, making it difficult to meet the stroke requirements of the movable three-person seats in caravans or buses for front and rear adjustment.

[0003] Therefore, a seat slide rail structure is needed to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this application discloses a seat slide rail structure, including a slide rail disposed at the lower end of a seat leg support. The slide rail includes a slide groove, a slider, a stop module, and a control handle. One end of the slider is embedded in the slide groove and slidably connected to the slide groove, and the other end of the slider is connected to the leg support. The stop module and the control handle cooperate to unlock the slide rail.

[0005] The stop module includes a stop block, a limiting member, and an elastic member. One end of the stop block extends into the groove and engages with the bottom of the groove to stop. The other end of the stop block is elastically and telescopically connected to the limiting member through the elastic member. The other end of the limiting member is connected to the foot bracket. When the control handle is adjusted, the stop block disengages from the bottom of the groove to unlock the slide rail; conversely, the slide rail is locked.

[0006] Furthermore, the slide rails are in two sets, symmetrically arranged corresponding to the left and right chair legs, and the control handle is located between the two sets of slide rails for synchronous adjustment and unlocking.

[0009] The stop block is connected to the elastic element at one end with a protrusion, and the upper end of the protrusion is provided with a screw hole that mates with the screw.

[0010] Furthermore, the stop block includes a front stop block and a rear stop block that are interconnected, and the limiting member includes a front limiting member and a rear limiting member.

[0011] Furthermore, a roller structure is provided on the contact surface between the slider and the groove to ensure smooth sliding of the slider.

[0012] Furthermore, the slider has a T-shaped structure or a Y-shaped structure.

[0013] Furthermore, the length of the slide groove is ≥1000mm, and the length of the slide rail is ≥1000mm.

[0026] Please refer to Figure 1-3As shown, a seat slide rail structure includes a slide rail 2 located at the lower end of a seat base 1. The slide rail 2 includes a slide groove 21, a slider 22, a stop module 23, and a control handle 24. One end of the slider 22 is embedded in the slide groove 21 and slidably connected to the slide groove 21. The other end of the slider 22 is connected to the base 1. The stop module 23 and the control handle 24 cooperate to unlock the slide rail 2. The stop module 23 includes a stop block 231, a limiting member 232, and an elastic member 233. One end of the stop block 231 extends into the slide groove 21 and engages with the bottom of the groove to stop. The other end of the stop block 231 is elastically and telescopically connected to the limiting member 232 through the elastic member 233. The other end of the limiting member 232 is connected to the bracket 1. That is, the stop block 231 is connected to the bracket 1 through the limiting block. It can be understood that both the stop module 23 and the slider 22 are connected to the bracket 1. The stop action of the stop block 231 can realize the simultaneous locking and unlocking of the stop module 23 and the slider 22, thereby realizing the stop (or unlocking and locking) of the slide rail 2. When the control handle 24 is adjusted, the stop block 231 disengages from the bottom of the groove to unlock the slide rail 2, and vice versa, the slide rail 2 is locked. Figure 1-3 The approximate location and structure of the stop module and slider are only shown.

[0027] Based on the above technical solution, there are two sets of slide rails 2, which are symmetrically arranged corresponding to the left and right chair legs. In other words, slide rails 2 are installed on both sides of the seat simultaneously. The control handle 24 is positioned between the two sets of slide rails 2 for synchronous adjustment and unlocking. The control handle 24 can be shaped like a "Z" to control both slide rails 2 simultaneously. Thus, the slide rails 2 have a double-sided, double-separated stop, effectively ensuring that foreign objects in the slide rail 21 do not affect its function.

[0028] In a preferred embodiment, the stop block 231 has a protruding tooth 2313 at one end of the contact groove bottom, and the groove bottom has a slot 211 that cooperates with the protruding tooth 2313. Thus, the stop block 231 can be locked well by inserting the protruding tooth 2313 into the slot 211.

[0029] Specifically, the elastic element 233 is a spring, the limiting element 232 can be a limiting plate, and the stop block 231 is connected to the spring and the limiting element 232 by a screw 234. That is, the spring passes through the screw 234, the screw 234 passes through the limiting element 232 and the spring and is connected to the stop block 231. That is, the screw 234 connects the components of the stop module 23 in series. One end of the spring abuts against the limiting element 232, and the other end abuts against the stop block 231 to provide downward elastic force so that the stop block 231 is better locked at the bottom of the groove.

[0030] In an optional embodiment, the stop block 231 is connected to the elastic element 233 at one end with a protrusion 2314, and the upper end of the protrusion 2314 is provided with a screw hole 2315 for easy engagement with the screw 234.

[0031] Furthermore, the stop block 231 includes a front stop block 2311 and a rear stop block 2312 connected to each other, and the limiting member 232 includes a front limiting member 2321 and a rear limiting member 2322. The front stop block 2311 is close to the slider 22, while the rear stop block 2312 is located at a more distant end, which facilitates the disassembly and replacement of the stop block 231 and can also ensure that the slide rail 2 can be used normally when foreign objects enter the slide rail 2 to a certain extent.

[0032] Preferably, a roller structure is provided on the contact surface between the slider 22 and the groove 21 to ensure smooth sliding of the slider 22. Of course, the roller structure can adopt an existing structure and can be set on the bottom surface or side surface of the slider, as long as it can achieve the corresponding function, which will not be elaborated here.

[0033] Furthermore, the slider 22 adopts a T-shaped or Y-shaped structure, and the corresponding groove 21 is designed as a fitting groove, which can effectively ensure that the function is not affected when there are foreign objects in the groove 21.

[0034] In a preferred embodiment, the length of the slide groove 21 is ≥1000mm and the length of the slide rail 2 is ≥1000mm, in order to meet the seat adjustment travel requirement of 1000mm or more.

[0035] Specifically, the non-handheld end of the control handle is hinged to the lower end of the stand 1. Optionally, a lifting part 241 is provided near the hinge of the control handle. The lifting part 241 is connected to a stop block 231, which allows the stop block 231 to be lifted and disengaged from the bottom of the slot to unlock the slide rail 2 when the control handle is turned. Of course, the control handle can adopt other structures, as long as it can achieve the corresponding unlocking function, which will not be elaborated here.

[0036] For the purpose of reducing weight and facilitating disassembly and assembly, the main body of slide rail 2 is made of aluminum alloy. Slide rail 2 and foot bracket 1 are assembled separately and connected by screws. The assembly structure of slide rail 2 and foot bracket 1 is assembled separately from the seat body and connected by screws.

[0037] The working principle of this utility model can be understood as follows: In the normal state, the control handle 24 is horizontal, and the stop block 231 is fixed to the bottom of the slide groove 21 under the action of the spring. The stop block 231 and the slider 22 are simultaneously connected to the foot bracket 1, so the slider 22 is not fixed and locked. Specifically, the protrusion 2313 of the stop block 231 can be inserted into the slot 211 at the bottom of the groove to stop the stop block 231 and the slider 22 in the slide groove 21, thereby locking the seat fixed on the sliding rail. When the seat needs to be moved forward and backward, the control handle 24 is pulled upward to rotate around the hinge point. The lifting part 241 moves upward and drives the stop block 231 to move upward and disengage from the bottom of the groove. At this time, the slider 22 and the slide rail 2 are unlocked. It can be understood that the user's body moves the seat forward and backward, thereby moving the slide rail 2. After the position is determined, the control handle is released, and the stop block 231 and the control handle 24 are reset under the action of the spring, and the slider 22 and the slide rail 2 are locked back together.

[0038] The seat slide rail structure provided in this application has at least the following beneficial effects:

[0039] 1. This application provides a high-strength, lightweight and space-optimized seat slide rail structure that meets the strength requirements of GB 15083 M1 class seats through slide rail structure design, which can better improve the user experience.

[0040] 2. By adopting double-sided double-segment slide rail stop (two sets of slide rails, front stop block and rear stop block, etc.), it is ensured that foreign objects in the slide rail will not affect the function. Slider: The slider group with rollers ensures smooth sliding.

[0041] 3. Slide rail body: Made of aluminum alloy to reduce weight, the slide rail body is designed with a stroke of more than 1000mm to ensure that the seat adjustment stroke requirements are met.

[0042] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
