Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically to a slide rail assembly, and more particularly to a slide rail assembly that can better protect the internal space of the lower rail. This slide rail assembly can be applied to the interior of a vehicle and can be used to adjust the position of the vehicle seat inside the vehicle. Background Technology

[0002] In related technologies, the slide rail assembly mainly consists of an upper rail and a lower rail. The lower rail is fixed, while the upper rail is set within the lower rail and can slide along it to adjust the position of the vehicle seat. Generally, the upper rail is shorter than the lower rail, therefore, the upper rail cannot completely cover the lower rail. During long-term use, dust and other impurities can easily enter the interior of the lower rail, which will affect the smoothness of the upper rail's sliding within the lower rail and may 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 remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a slide rail assembly in which the zipper assembly and the shielding assembly of the protective unit cooperate to form a double-layer protective structure, which can better achieve reliable protection for the slide rail unit. At the same time, the shielding assembly can be easily disassembled and assembled to improve disassembly and assembly efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a slide rail assembly, including a slide rail unit and a protective unit. The slide rail unit includes an upper rail assembly and a lower rail assembly, both of which extend along a first direction. The protective unit includes: a support assembly, comprising two support members arranged opposite each other along a second direction, the second direction and the first direction forming an angle, both support members being mounted on the lower rail assembly; a zipper assembly, comprising two zipper pieces and two zipper heads, the two zipper pieces arranged opposite each other along the second direction, the two zipper pieces being respectively mounted on the two support members, both zipper pieces having zipper teeth, both zipper heads being connected to the two zipper teeth, the two zipper heads being respectively located on both sides of the upper rail assembly in the first direction, and both zipper heads being connected to the upper rail assembly; and a concealing assembly, comprising two concealing strips arranged opposite each other along the second direction, the two concealing strips being detachably connected to the two support members, the concealing assembly being located on the upper side of the zipper assembly.

[0006] In the above scheme, the support component can form the structural foundation of the protective unit and can be used to install the zipper component and the concealing component. The two zipper pieces of the zipper component can be connected through the zipper head to form a sealed protective structure, which can effectively prevent dust and other impurities from entering the lower rail component, or foreign objects caused by stepping on it from entering the lower rail component. This can largely avoid structural damage and jamming inside the lower rail component, which is beneficial to ensuring the smooth sliding of the upper rail component relative to the lower rail component and the service life of the entire slide rail assembly.

[0007] Furthermore, both zipper heads of the zipper assembly can be connected to the upper rail assembly. During the displacement of the upper rail assembly relative to the lower rail assembly, the two zipper heads can be used to engage and disengage the two zipper pieces respectively, ensuring that the zipper assembly always maintains a sealed protective state, while not affecting the sliding of the upper rail assembly relative to the lower rail assembly.

[0008] The two concealing strips of the concealing component can be located on the upper side of the zipper assembly to provide a certain degree of concealment. This helps prevent dust and other impurities, or foreign objects caused by stepping, from falling into the zipper teeth, thus extending the lifespan of the zipper assembly. Furthermore, the two concealing strips and the two support members are detachably connected, allowing for easy disassembly and reassembly when the concealing strips show signs of aging or damage, facilitating quick assembly and disassembly of the protective unit.

[0009] Optionally, the masking strip is provided with a first snap-fit ​​portion, and the support member is provided with a first snap-fit ​​mating portion, wherein the first snap-fit ​​portion snaps into the first snap-fit ​​mating portion.

[0010] Optionally, the two zipper tabs are detachably connected to the two support members.

[0011] Optionally, the zipper piece has a second engaging portion at one end facing away from the zipper teeth in the second direction, and the support member has a second engaging engagement portion, with the second engaging portion engaging with the second engaging engagement portion.

[0012] Optionally, the zipper piece includes a zipper body and a fastener. The zipper body is provided with the zipper teeth. The fastener is provided at one end of the zipper body away from the zipper teeth along the second direction. The fastener is provided with the second snap-fit ​​portion.

[0013] Optionally, the support member includes an upper plate and a lower plate, the zipper piece and the concealing strip are both connected to the upper plate, and the lower plate is snapped onto the lower rail assembly.

[0014] Optionally, the lower rail assembly includes a lower rail body and a clamp, the clamp being fitted onto the outer side of the lower rail body, and the lower plate being inserted between the lower rail body and the clamp, with the lower plate and the clamp engaging.

[0015] Optionally, the support assembly further includes a support portion disposed between the upper plate and the lower rail assembly.

[0016] Optionally, the upper rail assembly includes an upper rail component, a lead screw component, and an electric drive component. Both zipper heads are connected to the upper rail component. The lead screw component is installed inside the lower rail assembly. The electric drive component is installed in the upper rail component, and the electric drive component and the lead screw component are connected in a transmission connection.

[0017] Optionally, the masking strip is made of silicone rubber. Attached Figure Description

[0035] Please refer to Figures 1-7 , Figure 1 This is a schematic diagram of the slide rail assembly provided in the embodiment of the present utility model; Figure 2 for Figure 1 Exploded view of the middle slide rail unit and the protective unit; Figure 3 for Figure 1 A magnified view of a portion of the image; Figure 4 A schematic diagram of the supporting components; Figure 5 This is a structural diagram of a zipper assembly; Figure 6 A schematic diagram of the structure of the component being concealed; Figure 7 for Figure 1 A schematic diagram in the first direction.

[0036] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a slide rail assembly that can be used in vehicles such as automobiles to adjust the position of the vehicle seat inside the vehicle. The slide rail assembly includes a slide rail unit 1000 and a protective 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 a first direction X. The upper rail assembly 1100 can be connected to a 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 be displaced relative to the lower rail assembly 1200 along the first direction X to adjust the position of the vehicle seat.

[0038] Combination Figure 3The lower rail assembly 1200 may include a lower rail body 1210. The lower rail body 1210 may include a lower rail body 1211 and two side rail bodies 1212. The lower rail body 1211 is used to connect to the vehicle floor, and the specific connection method may be, for example, a screw connection. The two side rail bodies 1212 can be located on the upper side of the lower rail body 1211, and the two side rail bodies 1212 can be arranged opposite each other along the second direction Y. The second direction Y and the first direction X can be arranged at an angle, such as 90 degrees. In this embodiment of the present invention, a third direction Z can also be defined. The third direction Z can be arranged at an angle with both the first direction X and the second direction Y, and the angle can also be 90 degrees. In some implementations, in this embodiment of the present invention, the first direction X is the front-rear 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 body 1212 includes a lower rail side plate 1212A, a lower rail top plate 1212B, and a lower rail flange 1212C.

[0040] The protective unit 2000 includes a support assembly 2100, a zipper assembly 2200, and a concealing assembly 2300. The support assembly 2100 includes two support members 2110 arranged opposite each other along a second direction Y, both of which are mounted on the lower rail assembly 1200. The zipper assembly 2200 includes two zipper tabs 2210 and two zipper heads 2220, the two zipper tabs 2210 also arranged opposite each other along the second direction Y; the two zipper tabs 2210 are respectively mounted on the two support members 2110, and each zipper tab 2210 is provided with a zipper tooth portion 2211A; the two zipper heads 2220 are each connected to the two zipper teeth portions 2211A, and the two zipper heads 2220 are respectively located on both sides of the upper rail assembly 1100 in the first direction X, and both zipper heads 2220 are connected to the upper rail assembly 1100. The concealing assembly 2300 includes two concealing strips 2310, which are detachably connected to two support members 2110 respectively. The concealing assembly 2300 is located on the upper side of the zipper assembly 2200.

[0041] Using the above scheme, the support component 2100 can form the structural foundation of the protective unit 2000, and can be used to install the zipper component 2200 and the concealing component 2300. The two zipper pieces 2210 of the zipper component 2200 can be connected through the zipper head 2220 to form a sealed protective structure, which can effectively prevent dust and other impurities from entering the lower rail component 1200, or foreign objects caused by stepping on them from entering the lower rail component 1200. This can largely avoid structural damage and jamming inside the lower rail component 1200, and help ensure the smooth sliding of the upper rail component 1100 relative to the lower rail component 1200, as well as the service life of the entire slide rail assembly.

[0042] Furthermore, both zipper 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 zipper heads 2220 can be used to achieve engagement and disengagement between the two zipper pieces 2210, so that the zipper assembly 2200 can always maintain a sealed protective state, while not affecting the sliding of the upper rail assembly 1100 relative to the lower rail assembly 1200.

[0043] The two concealing strips 2310 of the concealing component 2300 can be located on the upper side of the zipper component 2200 to provide a certain degree of concealment for the zipper component 2200. This can prevent dust and other impurities, or foreign objects caused by stepping, from falling into the zipper teeth 2211A of the zipper component 2200, thus helping to ensure the service life of the zipper component 2200. Furthermore, the two concealing strips 2310 and the two support members 2110 are detachably connected, so that when the concealing strips 2310 become aged or damaged, they can be easily replaced, facilitating the quick assembly and disassembly of the protective unit 2000.

[0044] As can be seen, in this embodiment of the present invention, the zipper assembly 2200 and the masking assembly 2300 of the protective unit 2000 can cooperate to form a double-layer protective structure, which can better achieve reliable protection for the slide rail unit 1000. At the same time, the masking assembly 2300 can be easily replaced to facilitate the quick disassembly and assembly of the protective unit 2000.

[0045] It should be understood that the dimensions of the protective unit 2000 in the first direction X and the dimensions of the lower rail assembly 1200 in the first direction X can be substantially the same, so as to provide better protection for the lower rail assembly 1200.

[0046] In some alternative implementations, such as Figure 3 , Figure 4 and Figure 6 As shown, the masking strip 2310 may be provided with a first snap-fit ​​portion 2311, and the support member 2110 may be provided with a first snap-fit ​​mating portion 2111A. The first snap-fit ​​portion 2311 may snap onto the first snap-fit ​​mating portion 2111A to achieve a detachable connection between the masking strip 2310 and the support member 2110.

[0047] Specifically, in the first engaging portion 2311 and the first engaging mating portion 2111A, one can be a protrusion and the other can be a groove. The outer contour of the protrusion and the inner contour of the groove can be matched. Taking the protrusion as an example, its cross-section perpendicular to the first direction X can be circular, elliptical, square, prismatic, triangular, etc., without limitation, as long as it can meet the engaging requirements of the first engaging portion 2311 and the first engaging mating portion 2111A.

[0048] In the implementation shown in the attached drawings, the extension direction of the first latching portion 2311 forms a non-90-degree angle with the third direction Z, that is, the first latching portion 2311 is inclined. In addition, in some other implementations of this utility model, the extension direction of the first latching portion 2311 and the third direction Z can also be parallel, that is, the first latching portion 2311 can also be arranged vertically.

[0049] It should be understood that, in addition to the snap-fit ​​connection method described above, the shielding strip 2310 and the support member 2110 can also be connected by other detachable connection methods such as screw connection, as long as the technical requirements for detachability are met.

[0050] Furthermore, this embodiment of the invention does not limit the specific material of the masking strip 2310. In practical applications, those skilled in the art can select the appropriate material according to specific needs, as long as it meets the requirements of use. For example, the masking strip 2310 can be made of silicone rubber. Silicone rubber can operate in a temperature range of -60℃ to 300℃ and has excellent high-temperature and low-temperature resistance, which can effectively solve the common problems currently faced in the industry: the masking strip cannot rebound to its initial state at high temperatures and rebounds slowly to its initial state at room temperature. Alternatively, the masking strip 2310 can also be made of thermoplastic vulcanizate (TPV), which has excellent properties such as low-temperature resistance and aging resistance.

[0051] In some alternative implementations, the two zipper tabs 2210 can also be detachably connected to the two support members 2110. In this way, the zipper tabs 2210 can be easily disassembled and assembled so that they can be replaced when they age or are damaged, thereby enabling quick assembly and disassembly of the protective unit 2000.

[0052] The detachable connection methods here can also include snap-fit, screw connection, etc.

[0053] Taking a snap-fit ​​connection as an example, the zipper piece 2210 may have a second snap-fit ​​portion 2212A at the end opposite to the zipper tooth portion 2211A in the second direction Y, and the support member 2110 may have a second snap-fit ​​mating portion 2111B. The second snap-fit ​​portion 2212A can snap onto the second snap-fit ​​mating portion 2111B. For the specific structural forms of the second snap-fit ​​portion 2212A and the second snap-fit ​​mating portion 2111B, please refer to the aforementioned descriptions of the first snap-fit ​​portion 2311 and the first snap-fit ​​mating portion 2111A, which will not be repeated here.

[0054] Combination Figure 5The zipper pull 2210 may include a pull body 2211 and a fastener 2212. The pull body 2211 may be provided with the aforementioned chain tooth portion 2211A. The end of the pull body 2211 facing away from the chain tooth portion 2211A in the second direction Y may be connected to the fastener 2212. The specific connection method may be, for example, sewing, molding, etc., which is not limited here, as long as it meets the requirements of use. The fastener 2212 may be provided with the aforementioned second engaging portion 2212A to facilitate the processing and preparation of the second engaging portion 2212A.

[0055] The material of the fastener 2212 can be the same as that of the aforementioned masking strip 2310.

[0056] In some alternative implementations, such as Figure 4 As shown, the support member 2110 may include an upper plate 2111 and a lower plate 2112.

[0057] The upper plate 2111 can be located on the upper side of the side rail 1212 and can directly or indirectly abut against the lower rail top plate 1212B of the side rail 1212. The aforementioned first snap-fit ​​part 2111A and second snap-fit ​​part 2111B can both be provided on the upper plate 2111 to facilitate the installation of the zipper piece 2210 and the cover strip 2310.

[0058] The lower plate 2112 can be snapped onto the lower rail assembly 1200. In this way, the support member 2110 and the lower rail assembly 1200 are also detachably connected. Once the support member 2110 ages or is damaged, it can be easily replaced, which is conducive to the quick assembly and disassembly of the protective unit 2000.

[0059] Combination Figure 7 The lower rail assembly 1200 may also include a clamp 1220, which can be mounted on the outside of the lower rail body 1210. The lower plate 2112 may be inserted between the lower rail body 1210 and the clamp 1220, and the lower plate 2112 may be snapped into the clamp 1220.

[0060] Specifically, the clamp 1220 may include a clamp bottom 1221 and two clamp sides 1222, which may be arranged opposite each other along the second direction Y. The clamp bottom 1221 may be located on the underside 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 2112 may be inserted between the clamp sides 1222 and the lower rail body 1210. The side of the clamp side 1222 facing the lower rail assembly 1200 forms a snap-fit ​​position 1222A. The lower plate 2112 may be provided with a snap-fit ​​connector 2112A, which can snap-fit ​​with the snap-fit ​​position 1222A.

[0061] The clamp side portion 1222 may also have a clamp flange 1222B, through which the clamp side portion 1222 can contact the upper plate 2111 to support the upper plate 2111. The clamp flange 1222B increases the contact area between the clamp side portion 1222 and the upper plate 2111, thereby improving the reliability of the clamp 1220's support for the upper plate 2111.

[0062] It should be understood that the above description of the specific structural forms of the support member 2110 and the lower rail assembly 1200, as well as the specific connection methods of the support member 2110 and the lower rail assembly 1200, is merely an exemplary illustration of the present utility model in conjunction with the accompanying drawings. It cannot be considered as a limitation on the scope of implementation of the slide rail assembly provided by the present utility model. In some other implementations of the present utility model, 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 only include two clamp sides 1222, which may be connected to the lower rail body 1210 by welding, screw connection, or other connection methods. As another example, the support member 2110 may also be directly connected to the lower rail body 1210 by screw connection, welding, or other connection methods. In this case, the lower rail assembly 1200 may omit the clamp 1220 to simplify the structure of the lower rail assembly 1200. For example, the support member 2110 may also consist only of the upper plate 2111, thus the structure of the support member 2110 can be relatively simple.

[0063] In some alternative implementations, the support component 2100 may also include a support portion 2120, which may be disposed between the upper plate 2111 and the lower rail component 1200, specifically between the upper plate 2111 and the lower rail top plate 1212B.

[0064] The support portion 2120 can be used to buffer vibration between the upper plate 2111 and the lower rail top plate 1212B, reducing collision noise between the support member 2110 and the lower rail assembly 1200, thereby reducing abnormal noise in the slide rail assembly provided in this embodiment of the present invention during actual application. At the same time, the support portion 2120 can also protect the support member 2110, reducing the possibility of damage to the support member 2110 due to vibration.

[0065] The aforementioned support portion 2120 may be made of a material with a certain degree of flexibility, such as felt or soft rubber. The aforementioned support member 2110 may be made of metal or non-metal, and there is no limitation on this. The aforementioned support portion 2120 may be an integral structure. Alternatively, the aforementioned support portion 2120 may also include at least two support portions, and each support portion may be arranged at intervals along the first direction X.

[0066] Please refer to Figures 8-10 , Figure 8 This is a schematic diagram of the upper rail assembly. Figure 9 An exploded view of the lead screw assembly and the lower rail assembly; Figure 10 This is a diagram showing the connection structure between the upper rail assembly and the zipper assembly.

[0067] In some alternative implementations, the slide rail assembly provided in this embodiment of the invention can be an electric slide rail. In this case, as... Figures 8-10 As shown, the upper rail assembly 1100 may include an upper rail component 1110, a lead screw component 1120, and an electric drive component 1130.

[0068] The upper rail component 1110 is the main structure of the upper rail assembly 1100. It can be partially disposed in the lower rail assembly 1200 and can slide along the lower rail assembly 1200. Specifically, the upper rail component 1110 may include an upper rail body 1111. The upper rail body 1111 may be provided with a rolling element 1112 or a sliding element. The rolling element 1112 may be a roller or the sliding element may be a slider or the like. The upper rail body 1111 can be displaced within the lower rail assembly 1200 by means of the rolling element 1112 or the sliding element.

[0069] In addition, the upper rail component 1110 may also be provided with a gap-eliminating element (not shown in the figure) to eliminate the gap between the upper rail component 1111 and the lower rail assembly 1200 in the second direction Y and the third direction Z, thereby improving the stability of the displacement of the upper rail component 1110 within the lower rail assembly 1200.

[0070] The upper rail component 1110 may also 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, for example, welding. The electric drive component 1130 may be a motor or the like, and the electric drive component 1130 may be mounted on the mounting plate 1113.

[0071] Both zipper heads 2220 can 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, the mounting plate 1113 can be provided with mounting portions 1113A at both ends of the first direction X. The zipper head 2220 can include a zipper head body 2221 and a handle portion 2222. The zipper head 2220 can be connected to the mounting portion 1113A through the handle portion 2222. The aforementioned mounting portion 1113A can specifically be a hook (such as...). Figure 8 and Figure 10 As shown), pins, etc., are not limited here. In short, anything that can meet the installation requirements for zipper head 2220 is acceptable.

[0072] like Figure 9 As shown, the lead screw assembly 1120 may include a lead screw body 1121 and a lead screw seat 1122. The lead screw seat 1122 can be connected and fixed to the lower rail body 1210 by connecting screws 1123. The lead screw body 1121 may be mounted on the lead screw seat 1122.
