Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a slide rail assembly, a sliding module and a vehicle. Background Art

[0002] In related art, a slide rail assembly primarily consists of an upper rail and a lower rail. The lower rail is fixed, while the upper rail is mounted within the lower rail and can slide along it to adjust the position of the vehicle seat. Generally speaking, the upper rail is shorter than the lower rail, so it cannot completely cover the lower rail. Over time, dust and other impurities can easily enter the lower rail, affecting the smooth sliding of the upper rail within the lower rail and even shortening 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

[0004] The purpose of the present invention is to provide a slide rail assembly, a sliding module and a vehicle, wherein the slide rail assembly is equipped with a protective unit, which can block the opening between the two lower rail top plates of the lower rail component, thereby reducing foreign matter from falling into the lower rail component and ensuring the smooth sliding of the upper rail component.

[0005] In order to solve the above technical problems, the present invention provides a slide rail assembly, including: a slide rail unit, the slide rail unit including an upper rail component and a lower rail component, the upper rail component and the lower rail component both extending along a first direction, the lower rail component including two lower rail top plates arranged opposite to each other along a second direction, the second direction and the first direction are arranged at an angle, and at least one of the lower rail top plates is provided with a guide cavity; a protective unit including a sealing assembly, the sealing assembly including a flexible sealing strip, the flexible sealing strip including a connected sealing section, a reversing section and a spare section, the sealing section being slidably connected between the two lower rail top plates, the two ends of the upper rail component along the first direction are connected to the sealing section, and the spare section is slidably connected to the guide cavity.

[0007] Furthermore, the sealing section and the two lower rail top plates are in a sliding fit, providing a sliding guide for the sealing section, thereby improving the smoothness of its sliding. More importantly, the sliding guidance provided by the lower rail top plates also effectively limits the installation of the sealing section by the lower rail top plates, preventing the sealing section from falling downwards into the lower rail component. This is of positive significance in ensuring the shielding effect of the sealing section.

[0008] In addition, the lower rail top plate is also provided with a guide cavity, in which the spare section of the flexible sealing strip can be accommodated, thereby avoiding occupying the internal space of the lower rail component and reducing the impact on the normal sliding of the upper rail component relative to the lower rail component. At the same time, the guide cavity can also guide the sliding of the spare section, and also improve the sliding smoothness of the spare section.

[0009] Optionally, the lower rail top plate provided with the guide cavity is further provided with a reversing groove, the reversing groove and the guide cavity are communicated, and the reversing section is provided in the reversing groove.

[0012] Optionally, the protection unit further includes a cover plate, which is mounted on the lower rail component and is located at at least one end portion of the lower rail component along the first direction.

[0047] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a slide rail assembly 100 that can be used in vehicles such as cars and can adjust the location of sliding bodies such as vehicle seats and consoles (CNSL) inside the vehicle.

[0048] The slide rail assembly 100 may include a slide rail unit 1000 .

[0049] The number of the slide rail unit 1000 may be one, or at least two, which may be determined in combination with the application requirements of different sliding bodies. When the number of the slide rail units 1000 is at least two, the slide rail units 1000 may be arranged at intervals.

[0050] For ease of description, in the embodiments of the present application, a first direction X, a second direction Y, and a third direction Z may be defined. Specifically, the first direction X may be the extension direction of the rail unit 1000, the second direction Y may be the direction in which the rail units 1000 are spaced apart, and the third direction Z may be a direction perpendicular to the vehicle floor. Generally speaking, the third direction Z is the up-down direction. Both the first direction X and the second direction Y may be perpendicular to the third direction Z. The first direction X and the second direction Y may be arranged at an angle, such as 90 degrees.

[0051] The slide rail unit 1000 includes an upper rail component 1100 and a lower rail component 1200. The upper rail component 1100 is used to connect to the sliding body, and the lower rail component 1200 is used to connect to the vehicle floor. The upper rail component 1100 can be mounted on the lower rail component 1200 and can be displaced relative to the lower rail component 1200 to adjust the position of the sliding body inside the vehicle.

[0052] In some implementations, such as Figure 3 and Figure 4 As shown, the lower rail component 1200 may include a lower rail bottom plate 1210, two lower rail side plates 1220 and two lower rail top plates 1230; the two lower rail side plates 1220 are arranged relative to each other along the second direction Y, and the two lower rail top plates 1230 are also arranged relative to each other along the second direction Y. The above-mentioned lower rail component 1200 may be an integrally formed one-piece structure; alternatively, at least some of the plates in the above-mentioned lower rail component 1200 may also be prepared separately and then assembled by welding or other connection methods; in short, as long as the final lower rail component 1200 can be formed. The specific structural forms of the lower rail bottom plate 1210, the lower rail side plates 1220 and the lower rail top plate 1230 are not limited here. In actual applications, those skilled in the art can make choices according to specific needs, as long as they can meet the requirements of use.

[0053] The lower rail component 1200 may further include a vehicle body locating member 1240 and a vehicle body connecting member 1250. The vehicle body locating member 1240 may be, for example, a pin, etc., which can achieve pre-positioning of the lower rail component 1200 and the vehicle floor. The vehicle body connecting member 1250 may be, for example, a bolt or screw, etc., which is used to connect and secure the lower rail component 1200.

[0054] like Figure 5 As shown, the upper rail component 1100 may include an upper rail body 1110. An adapter plate 1120 may be provided on the top of the upper rail body 1110, and the upper rail component 1100 may be connected to the sliding body through the adapter plate 1120. The specific connection method may be, for example, bolt connection, etc., which is not limited here.

[0055] The upper rail body 1110 may also be provided with bottom wheels 1130, side wheels 1140, and support blocks 1150. The bottom wheels 1130 may be roller structures such as rolling bearings, and are used to support and slide the upper rail component 1100, thereby improving the smooth sliding of the upper rail component 1100 within the lower rail component 1200. The side wheels 1140 may also be roller structures such as rolling bearings, and are used to abut against the lower rail side plates 1220 along the second direction Y, thereby eliminating the gap between the upper rail component 1100 and the lower rail component 1200 along the second direction Y. The support blocks 1150 may be rubber blocks, plastic blocks, etc., and are used to abut against the lower rail side plates 1220 along the third direction Z, thereby eliminating the gap between the upper rail component 1100 and the lower rail component 1200 along the third direction Z.

[0056] In the embodiment of the present application, the slide rail assembly 100 may be an electric slide rail, so as to improve the degree of automation of the slide rail assembly 100. Figure 1-Figure 5 The slide rail assembly 100 may further include a power unit 3000 .

[0057] The power unit 3000 may include a power generation unit 3100, a transmission shaft 3200, a gearbox 3300, and a transmission screw 3400. The power generation unit 3100 may be a motor, such as a servo motor or a stepper motor. The power generation unit 3100 may be disposed on the upper side of the upper rail component 1100 and may be connected to the transmission shaft 3200. The gearbox 3300 may be mounted on the inner side of the upper rail component 1100. The input end of the gearbox 3300 may be connected to the transmission shaft 3200, and the output end of the gearbox 3300 may be connected to the transmission screw 3400. Screw supports 3500 are provided at both axial ends of the transmission screw 3400, and the screw supports 3500 may be connected to the lower rail base plate 1210. With such an arrangement, when the power generating unit 3100 is started, the power generating unit 3100 can drive the gearbox 3300 to move along the transmission screw 3400, and the gearbox 3300 can drive the upper rail component 1100 to move along the lower rail component 1200, thereby realizing automatic adjustment of the position of the sliding body inside the vehicle.

[0058] It should be understood that the above description of the specific structure of the slide rail unit 1000 and the power unit 3000 in the slide rail assembly 100 is mainly illustrated in conjunction with the accompanying drawings, and this cannot be used as a limitation on the scope of implementation of the slide rail assembly 100 provided in the embodiment of the present invention. In some other implementations of the embodiment of the present invention, the slide rail assembly 100 may also adopt other structural forms. For example, the slide rail assembly 100 in the embodiment of the present application may also be a manual slide rail, in which case the aforementioned power unit 3000 may also be omitted. For another example, in the upper rail component 1100, the support block 1150 may also be replaced with a roller structure such as a rolling bearing. For another example, in the upper rail component 1100, the support block 1150 and the side wheel 1140 may also be combined into a clearance eliminating wheel, and the axis direction of the clearance eliminating wheel and the second direction Y may be arranged at an angle, that is, the clearance eliminating wheel may be arranged at an angle so that the clearance eliminating wheel can synchronously eliminate the clearance between the upper rail component 1100 and the lower rail component 1200 along the second direction Y and the third direction Z. This is also feasible.

[0059] Reference Figure 4 There is an opening P between the two lower rail top plates 1230 of the lower rail component 1200. When the upper rail component 1100 is installed on the lower rail component 1200, the adapter plate 1120 of the upper rail component 1100 can extend from the opening P to be connected and fixed to the sliding body. The upper rail component 1100 can cover the above-mentioned opening P.

[0060] However, as described in the Background Technology section, the length of the lower rail (i.e., its dimension along the first direction) is typically greater than that of the upper rail. In some cases, the length of the lower rail is significantly greater than that of the upper rail. This means that the upper rail only partially shields the opening, leaving the remaining unshielded openings exposed. Consequently, over extended use, foreign matter such as dust and grit can easily enter the lower rail, affecting the smooth sliding of the upper rail relative to the lower rail. These particles may even enter the power unit and damage it.

[0061] To address this issue, the slide rail assembly provided in the embodiment of the present application may further include a protective unit 2000. The protective unit 2000 may shield the opening P not shielded by the upper rail component 1100, thereby reducing the possibility of foreign matter entering the interior of the lower rail component 1200 and facilitating smooth sliding of the upper rail component 1100 relative to the lower rail component 1200. For implementations in which the power unit 3000 is present, the possibility of damage to the power unit 3000 may also be reduced.

[0062] The rail unit 1000 and the protection unit 2000 can be provided in a one-to-one correspondence, that is, one rail unit 1000 can be provided with one protection unit 2000 for protection. Figure 1 When the number of the slide rail units 1000 is set to two, the number of the protection units 2000 can also be two, and the two protection units 2000 can protect the two slide rail units 1000 in a one-to-one correspondence.

[0063] like Figure 6-Figure 8 As shown, combined with Figure 4 In the embodiment of the present application, at least one lower rail top plate 1230 is provided with a guide cavity 1231 , and the protection unit 2000 includes a sealing assembly 2200 .

[0064] The sealing assembly 2200 includes a flexible sealing strip 2210. The flexible sealing strip 2210 includes a connected sealing section 2210A, a reversing section 2210B, and a standby section 2210C. The sealing section 2210A can be slidably connected to two adjacent lower rail top plates 1230 along the second direction Y to shield the aforementioned opening P. The sealing section 2210A can be connected to both ends of the upper rail component 1100 along the first direction X, so that the sealing section 2210A can be displaced together with the upper rail component 1100. The standby section 2210C can be slidably connected to the guide cavity 1231.

[0065] Using the above-mentioned scheme, the slide rail assembly 100 provided in the embodiment of the present invention includes a protective unit 2000, the protective unit 2000 includes a sealing component 2200, the sealing component 2200 includes a flexible sealing strip 2210, the flexible sealing strip 2210 includes a sealing section 2210A, the sealing section 2210A is installed on the upper rail component 1100, and can be displaced with the upper rail component 1100, and the sealing section 2210A is slidably connected to the two lower rail top plates 1230, and can also cover the opening P between the lower rail top plates 1230. With such a configuration, the sealing component 2200 can better shield the opening P of the lower rail component 1200, and can largely prevent foreign matter from entering the lower rail component 1200, as well as the resulting defects such as poor sliding and abnormal sliding noise of the upper rail component 1100; for the slide rail assembly 100 including the power unit 3000, the above scheme can also reduce the damage caused by foreign matter to the power unit 3000, and can also improve the working stability and service life of the power unit 3000.

[0066] Furthermore, the sealing segment 2210A and the two lower rail top plates 1230 are in a sliding fit, providing a sliding guide for the sealing segment 2210A, thereby enhancing the smooth sliding of the sealing segment 2210A. More importantly, the sliding guidance provided by the lower rail top plates 1230 for the sealing segment 2210A also effectively limits the installation of the sealing segment 2210A by the lower rail top plates 1230, preventing the sealing segment 2210A from falling into the lower rail component 1200 along the third direction Z. This is of great significance in ensuring the shielding effect of the sealing segment 2210A.

[0067] In addition, the lower rail top plate 1230 is further provided with a guide cavity 1231. The spare section 2210C of the flexible sealing strip 2210 can be accommodated in the guide cavity 1231, thereby avoiding occupying the internal space of the lower rail component 1200 and reducing the impact on the normal sliding of the upper rail component 1100 relative to the lower rail component 1200. At the same time, the guide cavity 1231 can also guide the sliding of the spare section 2210C, and can also improve the sliding smoothness of the spare section 2210C.

[0068] It can be seen that the protection unit 2000 provided in the embodiment of the present invention mainly includes a sealing assembly 2200, which has a relatively small number of parts and a simple structural design; moreover, the sealing assembly 2200 is installed and stored using the lower rail top plate 1230, has a compact structure, high integration, basically does not require other additional space, and can also meet the miniaturization design requirements.

[0069] It should be understood that the above divisions into the sealing section 2210A, the reversing section 2210B, and the standby section 2210C are merely distinguishing descriptions based on the position of the flexible sealing strip 2210 relative to the lower rail top plate 1230, and do not specifically refer to a specific section in the flexible sealing strip 2210. In fact, as the upper rail component 1100 moves within the lower rail component 1200, the position of the corresponding section in the flexible sealing strip 2210 will change, allowing the corresponding section to switch between the sealing section 2210A, the reversing section 2210B, and the standby section 2210C. For example, see Figure 7 When the upper rail component 1100 moves to the left, the sealing section 2210A on the left side will become shorter, so that the section of the flexible sealing strip 2210 that originally belonged to the left sealing section 2210A will be partially switched to the reversing section 2210B, and the section of the flexible sealing strip 2210 that originally belonged to the left reversing section 2210B can at least partially enter the guide cavity 1231 and switch to the spare section 2210C; in this process, the sealing section 2210A on the right side will become longer, so that at least part of the section of the flexible sealing strip 2210 that originally belonged to the right reversing section 2210B can be switched to the sealing section 2210A, and at the same time, the section of the flexible sealing strip 2210 that originally belonged to the spare section 2210C will also be partially switched to the reversing section 2210B.

[0070] In some implementations, such as Figure 4 As shown, the lower rail top plate 1230 may be provided with a slide groove 2112 , and the sealing section 2210A may be specifically slidably connected in the slide groove 2112 .

[0071] Based on the configuration of the aforementioned chute 2112, the lower rail top plate 1230 may include two chute sidewalls disposed opposite each other along the third direction Z. Portions of the sealing segment 2210A may be located within the two chute sidewalls. These two chute sidewalls can partially shield the sealing segment 2210A, reducing the exposure of the sealing segment 2210A to the outside. This, in turn, reduces the intrusion of dust, grit, and other foreign matter into the sealing segment 2210A, thereby extending the service life of the sealing segment 2210A and, consequently, the entire flexible sealing strip 2210. Furthermore, the lower rail top plate 1230 is a long, rectangular plate, making it relatively easy to fabricate the chute 2112 thereon.

[0072] It should be understood that in some other implementations of the embodiments of the present invention, a slide groove 2112 may be provided on the flexible sealing strip 2210 , and then a sliding connection may be made between the slide groove 2112 of the flexible sealing strip 2210 and the lower rail top plate 1230 . This is also feasible.

[0073] In some implementations, such as Figure 2 and Figure 3As shown, the lower rail top plate 1230, which is provided with a guide cavity 1231, may also be provided with a reversing groove 1233. The reversing groove 1233 may be connected to the guide cavity 1231 and may be generally arc-shaped. The reversing segment 2210B may be disposed in the reversing groove 1233. The reversing groove 1233 can guide the reversing segment 2210B, thereby improving the smoothness of the switching of the flexible sealing strip 2210 between the sealing segment 2210A and the backup segment 2210C.

[0074] The above-mentioned reversing groove 1233 may have a notch facing upwards. This implementation method can be seen in Figure 2 and Figure 3 , to facilitate the installation of the flexible sealing strip 2210.

[0075] It should be understood that in some other implementations of the present invention, the lower rail top plate 1230 may not be provided with the aforementioned reversing groove 1233. For example, the reversing segment 2210B may be at least partially located on one side of the lower rail top plate 1230 along the first direction X, that is, the reversing segment 2210B may not be provided within the lower rail top plate 1230. For another example, the guide cavity 1231 may not be limited to the linear cavity shown in the accompanying drawings. The guide cavity 1231 itself may include a standby cavity and a reversing cavity. The standby cavity may be generally linear, while the reversing cavity may be generally arcuate. The reversing segment 2210B may be located within the reversing cavity, while the standby segment may be located within the standby cavity. In this case, the sealing segment 2210A and the reversing segment 2210B in the flexible sealing strip 2210 are both equivalently provided within the guide cavity 1231.

[0076] In some implementations, such as Figure 7 and Figure 8 As shown, the flexible sealing strip 2210 may include two sealing segments 2210A, two reversing segments 2210B and one spare segment 2210C.

[0077] The two sealing segments 2210A can be respectively connected to the two ends of the upper rail component 1100 along the first direction X. In this implementation, the number of the flexible sealing strip 2210 can be only one, and the flexible sealing strip 2210 and the upper rail component 1100 can be combined to form an annular structure. Only one of the two lower rail top plates 1230 can be provided with the guide cavity 1231, and the structure of the lower rail top plate 1230 can be simpler.

[0078] Here, the embodiment of the present invention does not limit the specific structural form of the flexible sealing strip 2210. In actual application, those skilled in the art can select it according to specific needs, as long as it can meet the requirements of use.

[0079] In a specific embodiment, the flexible sealing strip 2210 may include a plurality of sub-components 2211, and two adjacent sub-components 2211 may be rotatably connected to accommodate the bending deformation of the flexible sealing strip 2210. Figures 9-11 One end of the sub-component 2211 may form an insertion portion 2211A, which may be provided with a protrusion 2211B. The other end of the sub-component 2211 may be formed with a slot portion 2211C and a latch portion 2211D connected to the slot portion 2211C. During assembly, the insertion portion 2211A of one sub-component 2211 may be inserted into the slot portion 2211C of another sub-component 2211, and the protrusion 2211B may be latched into the latch portion 2211D, thereby connecting the two adjacent sub-components 2211. Furthermore, the two adjacent sub-components 2211 may also rotate around the connection between the protrusion 2211B and the latch portion 2211D, thereby realizing a rotatable design of the two adjacent sub-components 2211.

[0080] In addition, the flexible sealing strip 2210 can also adopt other structural forms. For example, see Figure 12 The flexible sealing strip 2210 may further include a transition piece 2212. The transition piece 2212 may be, for example, a flexible rope, an elastic band, a bendable strip, or the like, to accommodate the bending deformation of the flexible sealing strip 2210. Alternatively, when the transition piece 2212 does not need to function as the aforementioned reversing segment 2210B, the transition piece 2212 may be a rigid strip. The transition piece 2212 may be connected between at least two adjacent sub-components 2210, thereby reducing the number of sub-components 2210 used and thereby lowering costs. For another example, the flexible sealing strip 2210 may be a one-piece structure. For example, the flexible sealing strip 2210 may be a one-piece flexible strip or a bellows made of a material with certain deformation properties, such as rubber.

[0081] Combine Figure 9 and Figure 12 The sealing assembly 2200 may further include a connecting joint 2220, and the sealing section 2210A may be connected to the upper rail component 1100 via the connecting joint 2220. Figure 5 The adapter plate 1120 of the upper rail component 1100 is provided with a connecting portion 1121 , and the connecting joint 2220 can be specifically connected to the connecting portion 1121 .

[0082] Here, the embodiment of the present invention does not limit the specific structural form of the connecting joint 2220 and the connecting portion 1121. In actual application, those skilled in the art can also make settings as needed, as long as they can meet the requirements of use. For example, the connecting portion 1121 can be a first connecting hole, and the connecting joint 2220 can be provided with a second connecting hole 2221; during specific assembly, the first connecting hole and the second connecting hole 2221 can be aligned, and then the first connecting hole and the second connecting hole 2221 can be connected and fixed with the help of connecting bolts or the like. For another example, one of the connecting portion 1121 and the connecting joint 2220 can adopt a hole-type structure, and the other can be provided with a hanging structure in the form of a hook, etc., and then the connection and fixation of the connecting portion 1121 and the connecting joint 2220 can be achieved by hanging and matching the hanging structure and the hole-type structure.

[0083] In some implementations, the protection unit 2000 may further include a cover plate 2300. The cover plate 2300 may be mounted on the lower rail component 1200. Specifically, the cover plate 2300 may be located at at least one end of the lower rail component 1200 along the first direction X.

[0084] The cover plate 2300 can be used to cover the end of the lower rail top plate 1230 along the first direction X, for example, it can be used to cover the aforementioned reversing groove 1233, which can reduce the entry of foreign matter such as dust and gravel from the outside into the lower rail component 1200, and the resulting problems such as poor movement of the flexible sealing strip 2210.

[0085] Here, the embodiment of the present invention does not limit the specific connection method between the cover plate 2300 and the lower rail top plate 1230. In actual application, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use. For example, see Figure 14 The cover plate 2300 may include a main body 2310 and a clamping portion 2320. The clamping portion 2320 may be located at the lower side of the main body 2310. The lower rail top plate 1230 may be provided with a clamping hole. The cover plate 2300 can be clamped through the clamping portion 2320 and the clamping hole of the lower rail top plate 1230. The main body 2310 may also be provided with a positioning portion 2330. Figure 2 and Figure 3The lower rail top plate 1230 may also be provided with a positioning hole 1234, and the positioning portion 2330 may be inserted into the positioning hole 1234 to guide the snap-fit ​​assembly of the cover plate 2300, thereby conveniently achieving snap-fit ​​fixation of the cover plate 2300. It is understood that in some other implementations of the embodiments of the present invention, the snap-fit ​​portion 2320 may be provided on the lower rail top plate 1230, and the snap-fit ​​hole may be provided on the cover plate 2300. This is also feasible. For another example, the cover plate 2300 and the lower rail top plate 1230 may be connected and fixed by other connection methods such as welding, riveting, or screw connection.

[0086] Combine Figure 14 A cleaning portion 2340 may also be provided on the lower side of the cover plate 2300. The cleaning portion 2340 may specifically be a brush, etc. The cleaning portion 2340 is used to clean the sealing segment 2210A to remove foreign matter such as dust and gravel that falls on the upper side of the sealing segment 2210A, thereby reducing the impact of these foreign matter on the normal sliding of the flexible sealing strip 2210 and effectively extending the service life of the protective unit 2000.

[0087] Combine Figure 15 and Figure 16 In some other implementations, the cover plate 2300 may also be integrated with the aforementioned reversing groove 1233 . In this case, the reversing segment 2210B may be disposed in the reversing groove 1233 of the cover plate 2300 .

[0088] In the embodiment of the present application, the lower rail component 1200 is made of a rigid material, such as a metal material such as stainless steel. Therefore, the lower rail top plate 1230 has a relatively good structural rigidity. When in use, the lower rail top plate 1230 is not easy to deform, its installation position can remain unchanged for a relatively long time, and it is not easily affected by external environments such as temperature, so that the protective unit 2000 can ensure the protective effect for a relatively long time. In addition, the lower rail top plate 1230 made of a rigid material also has the performance of resisting deformation due to external forces. In this way, the protective unit 2000 in the embodiment of the present invention can also have an anti-trampling effect.

[0090] Please refer to Figure 17 , Figure 17 This is a top view of another slide rail assembly provided by the present invention.

[0091] The structure and function of the slide rail assembly 100 involved in the embodiment of the present invention are basically the same as those of the slide rail assembly 100 involved in the aforementioned embodiment 1. The similarities between the two will not be described again. The following mainly describes the differences between the two.

[0092] like Figure 17As shown, in an embodiment of the present invention, the flexible sealing strip 2210 may only include a sealing section 2210A, a reversing section 2210B, and a spare section 2210C. In this case, in order to effectively shield both sides of the upper rail component 1100 along the first direction X, a protective unit 2000 may be provided with two flexible sealing strips 2210, and the two ends of the upper rail component 1100 along the first direction X may be respectively connected to the two flexible sealing strips 2210; the two lower rail top plates 1230 may each be provided with a guide cavity 1231, and the spare sections 2210C of the two flexible sealing strips 2210 may be respectively disposed in the guide cavities 1231 of the two lower rail top plates 1230.

[0093] Example 3

[0094] An embodiment of the present invention also provides a sliding module, including a sliding body and a slide rail assembly 100. The slide rail assembly 100 can specifically be the slide rail assembly 100 involved in any implementation method in the aforementioned embodiments one to two. The sliding body can be installed on the slide rail assembly 100 so as to be slidably assembled through the slide rail assembly 100.

[0095] The embodiments of the present invention do not limit the specific type of the sliding body. In actual applications, those skilled in the art may determine the type based on the specific usage environment. For example, when the sliding module is used in a vehicle, the sliding body may be a vehicle seat, a secondary instrument panel, etc. The vehicle seat may be any of the front, middle, and rear seats.

[0096] Example 4

[0097] An embodiment of the present invention further provides a vehicle, which may specifically be an electric vehicle, a fuel vehicle, etc., and may include the sliding module in the fifth embodiment.

[0098] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
