Technical Field

[0001] This utility model relates to the field of displacement components, and more specifically, it relates to a damped guide rail slider assembly with starting resistance. Background Technology

[0002] Damped guide rail slider assemblies are mechanical components that add damping structures to the traditional guide rail slider structure to guide the displacement of objects. They are widely used in the furniture industry, such as sliding doors and windows, drawers, etc., and are also widely used in the interior kits of vehicles, such as sliding seat armrests, lifting TV screens, and telescopic tables.

[0003] The technical features of a novel damping slider disclosed in Chinese Patent Announcement No. CN215908252U are as follows: it includes a slide rail, a slider body slidably connected to the inner wall of the slide rail, two clips engaging between the slider body and the inner wall of the slide rail, a spring embedded between the clips and the outer wall of the slider body, two positioning holes formed on the outer wall of the slider body, copper inserts connected to the inner wall of the positioning holes, and multiple mounting holes for mounting the slide rail formed at the bottom of the slide rail.

[0004] The above-mentioned technical solution can only provide damping during movement, but cannot provide starting resistance. When applied to vehicles, it may cause abnormal movement of the interior trim due to the more bumpy operating environment. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a damping guide rail slider assembly with starting resistance. On the one hand, it can provide mechanical feedback for users to adjust to a certain position, and on the other hand, it can prevent abnormal movement of the interior trim kit when it is in a certain use position or in a retracted state.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a damping guide rail slider assembly with starting resistance, comprising a guide rail and a slider, wherein the guide rail and the slider have at least one friction contact surface, a damping element is provided between the friction contact surfaces, and there is at least one relative gap between the guide rail and the slider. The guide rail is provided with a resistance forming hole on one side of the relative gap, and the slider is provided with a resistance forming element on one side of the relative gap. The resistance forming element is embedded in the resistance forming hole at the starting point, and the resistance forming element disengages from the resistance forming hole by means of elastic deformation.

[0007] By adopting the above technical solution, in practical application, the basic displacement damping sensation is provided by the damping component; when the slider is in the start position or gear position, the resistance forming component is embedded in the resistance forming hole under the action of elastic force, which can provide mechanical feedback for the user to adjust to a certain gear, and prevent abnormal movement of the interior kit when it is in a certain use gear or in a retracted state.

[0008] The present invention is further configured such that: the cross-section of the guide rail is U-shaped, having a first friction line and a second friction line; the slider is always within the U-shaped clamp of the guide rail; and at least two damping elements are mirror-image arranged, with a set of damping elements mirror-image of each other contacting the first friction line and the second friction line respectively.

[0009] The present invention is further configured such that: the first friction line and the second friction line have an arc contact surface; the damping element includes an arc plate, a telescopic column and an elastic element; the inner arc surface of the arc plate is provided with an EPJ material part that fits into the arc contact surface; the slider is provided with an insertion hole for the telescopic column to slide and insert; the elastic element abuts against the telescopic column; and a group of damping elements that are mirror images of each other share a single elastic element.

[0010] The present invention is further configured such that: the slider is provided with an arc-shaped assembly groove for fitting the outer arc surface of the arc plate, the arc-shaped assembly groove is provided with a limiting groove, and the outer arc surface of the arc plate is provided with a limiting protrusion that slides and engages with the limiting groove.

[0011] The present invention is further configured such that: the slider is provided with a square window, the square window is used to connect a set of mutually mirrored insertion holes, the elastic element is located inside the square window, and the end of the telescopic column is provided with a hook part, the hook part passes through the insertion hole and hooks with the groove wall of the square window.

[0012] The present invention is further configured such that the telescopic column is a hollow tubular structure with deformable grooves.

[0013] The present invention is further configured such that the resistance forming element is a ball-head plunger.

[0014] The present invention is further configured such that: the guide rail is provided with a plurality of resistance forming holes, the number of resistance forming holes being the number of stops required for the displacement of the slider.

[0015] The present invention is further configured such that: the distance between the two resistance forming holes at the foremost end is a, the distance between the two resistance forming holes at the last end is a, the distance between the remaining adjacent resistance forming holes is not equal to a, and the slider is provided with two resistance forming members, the distance between the two resistance forming members being a.

[0016] The present invention is further configured such that: the resistance forming member is a strong magnet A bolted to the lower surface of the slider, and a strong magnet B is fitted into the gap inside the resistance forming hole; the strong magnet A protrudes from the lower surface of the slider, and both the strong magnet A and the strong magnet B are provided with an outer chamfer.

[0017] In summary, this utility model has the following beneficial effects: a set of mirror-image damping components share a single elastic component, thereby giving the damping components the ability to elastically expand and contract. On the one hand, this ensures that the EPJ material component of the arc plate is always precisely fitted to the first friction line or the second friction line. On the other hand, the damping force can be adaptively adjusted by replacing the elastic component. The elastic component can be directly adjusted and replaced through the square window, effectively improving the convenience of assembling this application into the interior trim kit. When the slider is in the start position or gear position, the resistance forming component is embedded in the resistance forming hole under the action of elastic force. On the one hand, this provides mechanical feedback for the user to adjust to a certain gear position. On the other hand, it prevents abnormal movement of the interior trim kit when it is in a certain use position or in the retracted state. It has a greater starting resistance in the fully retracted and fully extended states, further improving the practicality of the starting resistance. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: A damped guide rail slider assembly with starting resistance, such as Figure 1 , Figure 2 As shown, the device includes a guide rail 1 and a slider 2. The guide rail 1 and the slider 2 have two friction contact surfaces. Specifically, the cross-section of the guide rail 1 is U-shaped, and it has a first friction line 7 and a second friction line 8. The slider 2 is always within the U-shaped clamp of the guide rail 1, thereby limiting the movement of the slider 2 to only the direction of the guide rail 1.

[0022] like Figure 1 , Figure 2 As shown, damping elements 3 are respectively provided between the two friction contact surfaces. In this embodiment, there are four damping elements 3, and two that are mirror images of each other form a group. The group of damping elements 3 that are mirror images of each other are in contact with the first friction line 7 and the second friction line 8, so that the damping feeling on both sides of the slider 2 is more balanced.

[0023] In other embodiments, two or six damping elements 3 may be provided, depending on the specific length of the slider 2.

[0024] The specific structure of the damping element 3 in this embodiment is as follows: Figure 2 , Figure 3 As shown, the damping component 3 includes an arc-shaped plate 9, a telescopic column 10, and an elastic component 11. The first friction line 7 and the second friction line 8 have arc-shaped contact surfaces. Using arc-shaped contact surfaces for contact effectively reduces the processing difficulty compared to traditional parallel contact surfaces. It should be noted that the inner arc surface of the arc-shaped plate 9 is provided with two EPJ material parts 12 that fit against the arc-shaped contact surface, thereby achieving the technical effect of improving the smoothness of sliding and reducing wear. It should also be noted that the slider 2 has an insertion hole 20 for the telescopic column 10 to slide and insert. The elastic component 11 abuts against the telescopic column 10, and a set of damping components 3 that are mirror images of each other share a single elastic component 11, thereby giving the damping component 3 the ability to elastically expand and contract. On the one hand, it can ensure that the EPJ material parts 12 of the arc-shaped plate 9 are always precisely fitted against the first friction line 7 or the second friction line 8. On the other hand, the damping force can be adaptively adjusted by replacing the elastic component 11.

[0025] In this embodiment, the elastic element 11 needs to be a strong helical spring. In other embodiments, a spring sheet or a rubber elastic block can also be used.

[0026] To improve the stability of the damping component 3 during installation, such as Figure 3As shown, the slider 2 is formed with an arc-shaped assembly groove 13 that can fit the outer arc surface of the arc plate 9. The arc-shaped assembly groove 13 is formed with a limiting groove 14. The outer arc surface of the arc plate 9 is integrally formed with a limiting protrusion 15 that slides and fits into the limiting groove 14, thereby limiting the damping component 3 to only have the range of motion of extension and retraction, effectively improving the stability of its movable installation.

[0027] In this embodiment, the elastic element 11 can be adaptively replaced according to the magnitude of the damping. To facilitate the replacement of the elastic element 11, for example... Figure 3 As shown, a square window 16 is provided on the top surface of the slider 2. The square window 16 is used to connect a set of mirror-image sockets 20. The elastic element 11 is located inside the square window 16, so the elastic element 11 can be directly adjusted and replaced through the square window 16, which effectively improves the convenience of assembling this application into the interior trim kit.

[0028] It should be noted that, as Figure 3 As shown, the end of the telescopic column 10 is integrally formed with a hook part 17. The hook part 17 passes through the insertion hole 20 and hooks with the groove wall of the square window 16, thereby limiting the maximum extension of the damping member 3 and effectively preventing it from detaching from the slider 2.

[0029] It should also be noted that, such as Figure 3 As shown, the telescopic column 10 is an elastic material with a hollow tubular structure. It is integrally formed with a deformable groove 18, so that the telescopic column 10 can be directly inserted horizontally into the insertion hole 20 during assembly to complete the assembly of the damping component 3, effectively improving the ease of assembly.

[0030] The inventive point of the above-mentioned part of this embodiment is that it provides a guide rail slider damping structure that is different from the prior art. This embodiment also has a second inventive point, namely, the addition of a structure for starting resistance, the specific solution of which is as follows: Figure 1 , Figure 4 As shown, there is a relative gap 4 between the bottom surface of the groove of the guide rail 1 and the lower surface of the slider 2. The guide rail 1 is provided with a resistance forming hole 5 on one side of the relative gap 4, and the slider 2 is provided with a resistance forming member 6 on one side of the relative gap 4. The resistance forming member 6 is embedded in the resistance forming hole 5 at the starting position, and the resistance forming member 6 is disengaged from the resistance forming hole 5 by means of elastic deformation. When the slider 2 is in the starting position or gear position, the resistance forming member 6 is embedded in the resistance forming hole 5 by elastic force. On the one hand, it can provide mechanical feedback for the user to adjust to a certain gear, and on the other hand, it prevents the interior trim kit in a certain use gear or folded state from moving abnormally.

[0031] In this embodiment, the resistance forming element 6 is a ball-head plunger. The ball-head plunger has a conventional structure, which generally includes a housing with one end open, a ball that is rotatably and telescopically connected to the open end of the housing, and a compression spring between the ball and the bottom surface of the housing.

[0032] In other embodiments, the resistance forming element 6 may also be other spring steel balls or rubber rollers with elasticity.

[0033] To accommodate various stop gear requirements, such as Figure 2 As shown, the guide rail 1 is provided with multiple resistance forming holes 5. The number of resistance forming holes 5 is the number of displacement positions of the slider 2, so that starting resistance can be provided at different operating positions.

[0034] It should be noted that, as Figure 4 , Figure 5 As shown, the distance between the two resistance forming holes 5 at the front end is a, the distance between the two resistance forming holes 5 at the rear end is a, and the distance between the remaining adjacent resistance forming holes 5 is not equal to a. The slider 2 is provided with two resistance forming elements 6, and the distance between the two resistance forming elements 6 is a, so that there is a greater starting resistance in the fully retracted state and the fully extended state, further improving the practicality of the starting resistance.

[0035] It should also be noted that, such as Figure 4 , Figure 5 As shown, the opening end of the resistance forming hole 5 is machined with a chamfer 19, so that the angle of the chamfer 19 can be adjusted during machining according to the starting resistance required by the design. That is, the smaller the chamfer angle, the greater the starting resistance.

[0036] Example 2: While Example 1 used a mechanical elastic structure to achieve starting resistance, this example uses magnetic attraction to provide starting resistance to slider 2. The specific structure is as follows... Figure 6 As shown, the resistance forming component 6 is a strong magnet A21 bolted to the lower surface of the slider 2, and a strong magnet B22 is fitted into the resistance forming hole 5. The strong magnet A21 protrudes from the lower surface of the slider 2, and the amount of protrusion of the strong magnet A21 is less than the gap between the lower surface of the slider 2 and the bottom surface of the guide rail 1, so as to avoid friction between the strong magnet A21 and the guide rail 1 when the slider 2 leaves the starting resistance position. Both the strong magnet A21 and the strong magnet B22 are processed with an outer chamfer 23, so as to avoid interference between the strong magnet B22 and the strong magnet A21 due to the strong magnet rising too fast due to magnetic force.

[0037] The motion process of this scheme is as follows: Figure 7As shown, when slider 2 is away from the starting resistance position, strong magnet B22 sinks due to gravity. When slider 2 moves to a point where strong magnet A21 is close to strong magnet B22, strong magnet B22 floats up due to magnetic force. At this time, the outer chamfers 23 of strong magnet A21 and strong magnet B22 come into contact with each other, thereby decelerating and buffering slider 2. When slider 2 continues to move towards the starting resistance position, the two outer chamfers 23 work together to form a downward component force, forcing strong magnet B22 to move down. When strong magnet B22 moves down to the point where its upper surface is on the same plane as the lower surface of strong magnet A21, the blocking force disappears, and the magnetic force generates a pulling force to help slider 2 move until strong magnet A21 and strong magnet B22 are in a face-to-face attraction state, thereby providing starting resistance for slider 2. In summary, this embodiment adopts a magnetic attraction scheme, which not only provides starting resistance but also has the technical effects of decelerating and buffering slider 2 and assisting movement to the starting resistance position.

[0038] It should be noted that the guide rail 1 and slider 2 in this embodiment are made of lightweight aluminum alloy that cannot be magnetized.

[0039] It should also be noted that in this embodiment, the guide rail 1 is arranged horizontally upwards, and the strong magnet B22 can be reset by gravity. When it is used in an application where the strong magnet B22 cannot be reset by gravity, a magnetic adsorption body such as an iron sheet can be fixed at the bottom of the resistance forming hole 5, or a tension spring can be used to reset the strong magnet B22.

[0040] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
