Description

Technical Field

[0001] The present invention relates to the technical field of slide rails, and in particular to a slide rail assembly, and in particular to a slide rail assembly capable of better protecting the inner space of a lower rail. The slide rail assembly can be applied to the interior of a vehicle and can be used to adjust the position of a vehicle seat inside the vehicle. Background Art

[0002] In the related art, the slide rail assembly is mainly composed of an upper rail and a lower rail. The lower rail is fixed, while the upper rail is arranged in the lower rail and can slide along the lower rail to adjust the position of the vehicle seat. Generally speaking, the length of the upper rail is shorter than that of the lower rail, so the upper rail cannot completely cover the lower rail. During long-term use, dust and other impurities are easy to enter the lower rail, which will affect the sliding smoothness of the upper rail in the lower rail, and even affect the service life of the slide rail assembly.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0035] Please refer to Figures 1 - 7 , Figure 1 which is a schematic structural view of the slide rail assembly provided by the embodiments of the present invention; Figure 2 is Figure 1 an exploded view of the slide rail unit and the protection unit in Figure 3 is Figure 1 a partial enlarged view of Figure 4 a schematic structural view of the support assembly; Figure 5 a schematic structural view of the zipper assembly; Figure 6 a schematic structural view of the covering assembly; Figure 7 is Figure 1 a schematic view in the first direction.

[0036] As Figure 1 and Figure 2 shown, the embodiments of the present invention provide a slide rail assembly, which can be used in vehicles such as automobiles and can adjust the position of the vehicle seat inside the vehicle. The slide rail assembly includes a slide rail unit 1000 and a protection unit 2000.

[0037] The slide rail unit 1000 includes an upper rail assembly 1100 and a lower rail assembly 1200. Both the upper rail assembly 1100 and the lower rail assembly 1200 extend along the first direction X. The upper rail assembly 1100 can be connected to the vehicle seat. The lower rail assembly 1200 can be connected to the vehicle floor. The upper rail assembly 1100 can be installed in the lower rail assembly 1200 and can displace relative to the lower rail assembly 1200 along the first direction X so as to adjust the position of the vehicle seat.

[0038] Combined with Figure 3, the lower rail assembly 1200 may include a lower rail body 1210. The lower rail body 1210 may include a lower rail section 1211 and two side rail sections 1212. The lower rail section 1211 is used to connect to the vehicle floor, and the specific connection method may be, for example, screw connection. The two side rail sections 1212 may both be located on the upper side of the lower rail section 1211, and the two side rail sections 1212 may be arranged opposite to each other along the second direction Y. The second direction Y and the first direction X may be arranged at an angle, and this angle may be, for example, 90 degrees. In the embodiments of the present invention, a third direction Z may also be defined, and the third direction Z and the first direction X and the second direction Y may all be arranged at an angle, and this angle may also be 90 degrees. In some implementation manners, the first direction X in the embodiments of the present invention is the front-back direction of the vehicle, the second direction Y is the left-right direction of the vehicle, and the third direction Z is the up-down direction or the vertical direction.

[0039] The side rail section 1212 includes a lower rail side plate 1212A, a lower rail top plate 1212B, and a lower rail flange 1212C.

[0040] The protection unit 2000 includes a support assembly 2100, a zipper assembly 2200, and a covering assembly 2300. The support assembly 2100 includes two supports 2110 arranged opposite to each other along the second direction Y, and both supports 2110 are installed on the lower rail assembly 1200. The zipper assembly 2200 includes two zipper tapes 2210 and two zipper sliders 2220, and the two zipper tapes 2210 are also arranged opposite to each other along the second direction Y; the two zipper tapes 2210 are respectively installed on the two supports 2110, and both zipper tapes 2210 are provided with tooth portions 2211A; the two zipper sliders 2220 are both connected to the two tooth portions 2211A, and the two zipper sliders 2220 are respectively located on both sides of the upper rail assembly 1100 in the first direction X, and both zipper sliders 2220 are connected to the upper rail assembly 1100. The covering assembly 2300 includes two covering strips 2310, and the two covering strips 2310 are respectively detachably connected to the two supports 2110, and the covering assembly 2300 is located above the zipper assembly 2200.

[0041] Adopting the above solution, the support assembly 2100 can form the structural basis of the protection unit 2000 and can be used to realize the installation of the zipper assembly 2200 and the covering assembly 2300. The two zipper tapes 2210 of the zipper assembly 2200 can be connected through the zipper sliders 2220 to form a closed protection structure, which can better block dust and other impurities from entering the lower rail assembly 1200, or foreign objects from entering the lower rail assembly 1200 due to trampling, etc., thereby can largely avoid the structural damage, jamming, etc. inside the lower rail assembly 1200, which is beneficial to ensuring the smooth sliding of the upper rail assembly 1100 relative to the lower rail assembly 1200 and the service life of the entire slide rail assembly.

[0042] Moreover, both of the two slider heads 2220 of the zipper assembly 2200 can be connected to the upper rail assembly 1100. During the displacement of the upper rail assembly 1100 relative to the lower rail assembly 1200, the two slider heads 2220 can be respectively used to realize the engagement and separation between the two zipper tapes 2210, so that the zipper assembly 2200 can always maintain a closed protective state. At the same time, it will not affect the sliding of the upper rail assembly 1100 relative to the lower rail assembly 1200.

[0043] The two covering strips 2310 of the covering assembly 2300 can be located above the zipper assembly 2200 to be used for covering the zipper assembly 2200 to a certain extent, and can block dust and other impurities or foreign objects caused by trampling and the like from falling into the teeth portion 2211A of the zipper assembly 2200 to a certain extent, which is beneficial to ensuring the service life of the zipper assembly 2200. Moreover, the two covering strips 2310 and the two support members 2110 are detachably connected, so that when the covering strips 2310 are aged or damaged, etc., they can be conveniently replaced, so as to quickly realize the disassembly and assembly of the protection unit 2000.

[0044] It can be seen that in the embodiment of the present invention, the zipper assembly 2200 and the covering assembly 2300 of the protection unit 2000 cooperate with each other to form a double-layer protection structure in the up-and-down direction, which can better realize the reliable protection of the slide rail unit 1000. At the same time, the covering assembly 2300 can also be conveniently replaced to facilitate the quick disassembly and assembly of the protection unit 2000.

[0045] It should be understood that the size of the protection unit 2000 in the first direction X and the size of the lower rail assembly 1200 in the first direction X can be basically the same to facilitate better protection of the lower rail assembly 1200.

[0046] In some implementation manners, as Figure 3 、 Figure 4 and Figure 6 shown, the covering strip 2310 can be provided with a first clamping portion 2311, and the support member 2110 can be provided with a first clamping and cooperating portion 2111A. The first clamping portion 2311 can be clamped in the first clamping and cooperating portion 2111A to realize the detachable connection between the covering strip 2310 and the support member 2110.

[0047] Specifically, in the first clamping portion 2311 and the first clamping and cooperating portion 2111A, one can be a convex block portion and the other can be a groove portion, and the outer contour of the convex block portion and the inner contour of the groove portion can be adapted to each other. Taking the convex block portion as an example, its cross-section perpendicular to the first direction X can be circular, elliptical, square, rhombus, triangular, etc., which is not limited herein as long as it can meet the clamping requirements of the first clamping portion 2311 and the first clamping and cooperating portion 2111A.

[0048] In the implementation of the drawings, the extending direction of the first clamping portion 2311 forms a non-90-degree angle with the third direction Z, that is, the first clamping portion 2311 is inclined. In addition, in some other implementation manners of the embodiments of the present invention, the extending direction of the first clamping portion 2311 may also be parallel to the third direction Z, that is, the first clamping portion 2311 may also be arranged in the vertical direction.

[0049] In addition, the embodiments of the present invention do not limit the specific material of the shielding strip 2310. In practical applications, those skilled in the art can select according to specific needs as long as the requirements of use can be met. For example, the shielding strip 2310 may be made of silicone rubber, which can work in the temperature range of -60°C to 300°C and has excellent high-temperature resistance, low-temperature resistance and other characteristics, and can well solve the common problems faced in the current industry: the shielding strip cannot rebound to the initial state at high temperature and rebounds slowly to the initial state at normal temperature. For another example, the shielding strip 2310 may also be made of thermoplastic vulcanizate (TPV), and the thermoplastic vulcanizate may have excellent characteristics such as low-temperature resistance and aging resistance.

[0050] In some alternative implementation manners, the two zipper sliders 2210 may also be detachably connected to the two support members 2110 respectively. In this way, the zipper sliders 2210 can also be conveniently disassembled and assembled, so as to be replaced when the zipper sliders 2210 are aged or damaged, and thus the disassembly and assembly of the protection unit 2000 can be quickly realized.

[0051] The detachable connection manner here may specifically be clamping.

[0052] In detail, at one end of the zipper slider 2210 departing from the tooth portion 2211A in the second direction Y, a second clamping portion 2212A may be provided, and the support member 2110 may be provided with a second clamping and cooperating portion 2111B, and the second clamping portion 2212A may be clamped to the second clamping and cooperating portion 2111B. For the specific structural forms of the second clamping portion 2212A and the second clamping and cooperating portion 2111B, reference may be made to the relevant descriptions of the first clamping portion 2311 and the first clamping and cooperating portion 2111A above, and no repetitive description will be made here.

[0053] Combined with Figure 5, the slider piece 2210 may include a slider body 2211 and a fixing member 2212. The slider body 2211 may be provided with the above-mentioned slider teeth portion 2211A. One end of the slider body 2211 facing away from the slider teeth portion 2211A in the second direction Y may be connected to the fixing member 2212. The specific connection method may be, for example, sewing, molding, etc., which is not limited herein as long as it can meet the usage requirements. The fixing member 2212 may be provided with the above-mentioned second clamping portion 2212A to facilitate the processing and preparation of the second clamping portion 2212A.

[0054] The material of the fixing member 2212 may be the same as that of the aforementioned covering strip 2310.

[0055] In some alternative implementation manners, such as Figure 4 shown, the support member 2110 may include an upper plate body 2111 and a lower plate body 2112.

[0056] The upper plate body 2111 may be located above the side rail body 1212 and can be in direct or indirect contact with the lower rail top plate 1212B of the side rail body 1212. The aforementioned first clamping and fitting portion 2111A and second clamping and fitting portion 2111B may both be provided on the upper plate body 2111 to facilitate the installation of the slider piece 2210 and the covering strip 2310.

[0057] The lower plate body 2112 may be clamped and assembled to the lower rail assembly 1200. In this way, the connection between the support member 2110 and the lower rail assembly 1200 is also detachable. Once the support member 2110 is aged or damaged, the support member 2110 can be conveniently replaced, which is beneficial to the rapid disassembly and assembly of the protection unit 2000.

[0058] Combined with Figure 7 , the lower rail assembly 1200 may further include a clamp 1220. The clamp 1220 may be assembled on the outer side of the lower rail body 1210. The lower plate body 2112 may be inserted between the lower rail body 1210 and the clamp 1220, and the lower plate body 2112 may be clamped to the clamp 1220.

[0059] Specifically, the clamp 1220 may include a clamp bottom 1221 and two clamp sides 1222. The two clamp sides 1222 may be oppositely arranged along the second direction Y. The clamp bottom 1221 may be located on the lower side of the lower rail body 1210 and may be fixed by means of the connection between the lower rail body 1210 and the vehicle floor. The two clamp sides 1222 may be located on both sides of the lower rail body 1210 in the second direction Y. The lower plate body 2112 may be inserted between the clamp side 1222 and the lower rail body 1210. A clamping position 1222A is formed on the surface of the clamp side 1222 facing the lower rail assembly 1200. The lower plate body 2112 may be provided with a clamping head 2112A, and the clamping head 2112A may be clamped with the clamping position 1222A.

[0060] The clamp side 1222 may further have a clamp flange 1222B. The clamp side 1222 may contact the upper plate body 2111 through the clamp flange 1222B to support the upper plate body 2111. The setting of the clamp flange 1222B can increase the contact area between the clamp side 1222 and the upper plate body 2111, and can improve the support reliability of the clamp 1220 for the upper plate body 2111.

[0061] It should be understood that the above descriptions of the specific structural forms of the support member 2110 and the lower rail assembly 1200, as well as the specific connection methods between the support member 2110 and the lower rail assembly 1200, are only exemplary descriptions made in combination with the accompanying drawings in the embodiments of the present invention, and they cannot be used to limit the implementation scope of the slide rail assembly provided by the embodiments of the present invention. In some other implementation manners of the embodiments of the present invention, the support member 2110 and the lower rail assembly 1200 may also adopt other structural forms and connection methods. For example, the clamp 1220 may also only include two clamp sides 1222, and the two clamp sides 1222 may be connected to the lower rail body 1210 by connection methods such as welding and screw connection. For another example, the support member 2110 may also be directly connected to the lower rail body 1210 by connection methods such as screw connection and welding. At this time, the clamp 1220 of the lower rail assembly 1200 may also be omitted to simplify the structure of the lower rail assembly 1200. For another example, the support member 2110 may also only include the upper plate body 2111, so that the structural form of the support member 2110 may be relatively simple.

[0062] In some optional implementation manners, the support assembly 2100 may further include a support portion 2120. The support portion 2120 may be disposed between the upper plate body 2111 and the lower rail assembly 1200, specifically between the upper plate body 2111 and the lower rail top plate 1212B.

[0063] The supporting part 2120 can be used to achieve vibration buffering between the upper plate body 2111 and the lower rail top plate 1212B, which can reduce the collision noise between the support member 2110 and the lower rail assembly 1200, thereby reducing the abnormal noise of the slide rail assembly provided by the embodiment of the present invention during actual use. At the same time, the supporting part 2120 can also protect the support member 2110 and reduce the situation where the support member 2110 is damaged due to vibration.

[0064] Specifically, the above-mentioned supporting part 2120 can be prepared by using materials with certain flexible deformation such as felt and soft rubber. The above-mentioned support member 2110 can be made of metal or non-metal materials, which is not limited herein. The above-mentioned supporting part 2120 can be an integral structure. Or, the above-mentioned supporting part 2120 can also include at least two supporting sub-parts, and each supporting sub-part can be arranged at intervals along the first direction X.

[0065] Please refer to Figures 8 - 10 , Figure 8 which is a schematic structural diagram of the upper rail assembly; Figure 9 which is an exploded view of the lead screw component and the lower rail assembly; Figure 10 which is a connection structure diagram of the upper rail assembly and the zipper assembly.

[0066] In some alternative implementation manners, the slide rail assembly provided by the embodiment of the present invention can be an electric slide rail. At this time, as Figures 8 - 10 shown, the upper rail assembly 1100 can include an upper rail component 1110, a lead screw component 1120, and an electric drive component 1130.

[0067] The upper rail component 1110 is the main structure of the upper rail assembly 1100. It can be partially arranged in the lower rail assembly 1200 and can slide along the lower rail assembly 1200. Specifically, the upper rail component 1110 can include an upper rail body 1111. The upper rail body 1111 can be provided with rolling elements 1112 or sliding elements. The rolling elements 1112 can specifically be rollers, etc., and the sliding elements can specifically be sliders, etc. The upper rail body 1111 can displace within the lower rail assembly 1200 through the rolling elements 1112 or the sliding elements.

[0068] In addition, the upper rail component 1110 can also be provided with a backlash elimination element (not shown in the figure) to eliminate the gaps between the upper rail component 1110 and the lower rail assembly 1200 in the second direction Y and the third direction Z, thereby improving the displacement stability of the upper rail component 1110 within the lower rail assembly 1200.

[0069] The upper rail component 1110 may further include a mounting plate 1113. The mounting plate 1113 may be located on the upper side of the upper rail body 1111 and may be fixedly connected to the upper rail body 1111. The specific fixed connection method may be welding or the like. The electric drive component 1130 may specifically be a motor or the like, and the electric drive component 1130 may be mounted on the mounting plate 1113.

[0070] Both of the two zipper heads 2220 may be connected to the upper rail component 1110 so as to be displaced along the first direction X under the drive of the upper rail component 1110. Specifically, mounting portions 1113A may be provided at both ends of the mounting plate 1113 in the first direction X.
