Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a slide rail assembly, a sliding module, and a 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, a sliding module, and a vehicle. The slide rail assembly is equipped with a protective unit, which can seal the opening between the two lower rail top plates of the lower rail component, thereby reducing the amount of foreign objects falling into the lower rail component and ensuring the smooth sliding of the upper rail component.

[0005] To solve the above-mentioned technical problems, this utility model provides a slide rail assembly, comprising: a slide rail unit, the slide rail unit including an upper rail component and a lower rail component, both the upper rail component and the lower rail component extending along a first direction, the lower rail component including two lower rail top plates disposed opposite each other along a second direction, the second direction and the first direction being disposed at an angle, at least one of the lower rail top plates being provided with a guide cavity; and a protective unit, including a sealing assembly, the sealing assembly including a flexible sealing strip, the flexible sealing strip including a sealing section, a reversing section and a spare section connected together, the sealing section being slidably connected between the two lower rail top plates, the upper rail component having the sealing section connected to both ends along the first direction, and the spare section being slidably connected to the guide cavity.

[0006] In the above solution, the protective unit includes a sealing component, which includes a flexible sealing strip and a sealing section. The sealing section is installed on the upper rail component and can move with the upper rail component. The sealing section is slidably connected to the top plates of the two lower rails and can cover the opening between the top plates of the two lower rails. This can largely prevent foreign objects from entering the lower rail component and avoid defects such as poor sliding and abnormal sliding noise of the upper rail component.

[0007] Furthermore, the sealing section and the two lower rail top plates are in a sliding fit, and the two lower rail top plates can guide the sealing section to slide smoothly. More importantly, the sliding guidance of the sealing section by the lower rail top plates also serves as an installation limit for the sealing section, preventing it from falling downwards into the lower rail components. This is of positive significance for ensuring the shielding effect of the sealing section.

[0008] In addition, the top plate of the lower rail is also equipped with a guide cavity, in which the spare section of the flexible sealing strip can be housed. This avoids occupying the internal space of the lower rail component and reduces 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 spare section to slide smoothly.

[0009] Optionally, the lower rail top plate with the guide cavity is also provided with a reversing groove, the reversing groove is connected to the guide cavity, and the reversing section is disposed in the reversing groove.

[0010] Optionally, the flexible sealing strip includes two sealing sections, two reversing sections, and a spare section, with the two sealing sections respectively connected to the two ends of the upper rail component along the first direction.

[0011] Optionally, the flexible sealing strip includes a sealing section, a reversing section, and a spare section. The upper rail component is connected to two flexible sealing strips at its two ends along the first direction, and the spare sections of the two flexible sealing strips are respectively disposed in the guide cavities of the two lower rail top plates.

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

[0013] Optionally, a cleaning section is provided on the lower side of the cover plate, the cleaning section being used to clean the sealing section; and / or, the cover plate is provided with a reversing groove, the reversing section being located in the reversing groove.

[0014] Optionally, the lower rail top plate is provided with a groove, and the sealing section is slidably connected to the groove; and / or, the lower rail top plate is made of a rigid material.

[0015] Optionally, the flexible sealing strip includes multiple sub-components, with adjacent sub-components rotatably connected; or, the flexible sealing strip includes multiple sub-components, with at least two adjacent sub-components connected by a transition connector; or, the flexible sealing strip is an integral structure.

[0016] This utility model also provides a sliding module, including a sliding body and a slide rail assembly, wherein the slide rail assembly is the slide rail assembly described above, and the sliding body is mounted on the slide rail assembly.

[0017] This utility model also provides a vehicle, including a sliding module, wherein the sliding module is the sliding module described above. Attached Figure Description

[0047] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a slide rail assembly 100, which can be used in vehicles such as automobiles, and can adjust the setting position of sliding bodies such as vehicle seats and sub-dashboards (CONSOLE, CNSL) inside the vehicle.

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

[0049] The number of slide rail units 1000 can be one, or at least two, depending on the application requirements of different sliding bodies. When there are at least two slide rail units 1000, the slide rail units 1000 can be arranged at intervals.

[0050] For ease of description, in this embodiment, a first direction X, a second direction Y, and a third direction Z can be defined. Specifically, the first direction X can be the extension direction of the slide rail unit 1000, the second direction Y can be the direction in which the slide rail units 1000 are spaced apart, and the third direction Z can be a direction perpendicular to the vehicle floor. Generally, the third direction Z is the vertical direction. Both the first direction X and the second direction Y can be perpendicular to the third direction Z, and the first direction X and the second direction Y can be set 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 with the sliding body, and the lower rail component 1200 is used to connect with the vehicle floor. The upper rail component 1100 can be installed on the lower rail component 1200, and the upper rail component 1100 can be displaced relative to the lower rail component 1200 to adjust the installation position of the sliding body inside the vehicle.

[0052] In some implementations, such as Figure 3 and Figure 4As shown, the lower rail component 1200 may include a lower rail base plate 1210, two lower rail side plates 1220, and two lower rail top plates 1230; the two lower rail side plates 1220 are arranged opposite each other along the second direction Y, and the two lower rail top plates 1230 are also arranged opposite each other along the second direction Y. The lower rail component 1200 can be an integrally formed structure; or, at least some of the plates in the lower rail component 1200 can 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, it is acceptable. The specific structural forms of the lower rail base plate 1210, lower rail side plates 1220, and lower rail top plates 1230 are not limited here. In practical applications, those skilled in the art can select according to specific needs, as long as the requirements of use are met.

[0053] The lower rail component 1200 may further include a vehicle body positioning component 1240 and a vehicle body connecting component 1250. The vehicle body positioning component 1240 may be, for example, a pin, which enables pre-positioning of the lower rail component 1200 and the vehicle floor. The vehicle body connecting component 1250 may be, for example, a bolt or screw, which is used to connect and fix 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. 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, a bolt connection, etc., which is not limited here.

[0055] The upper rail body 1110 may also be equipped with a bottom wheel 1130, a side wheel 1140, and a support block 1150. The bottom wheel 1130, for example, can be a rolling bearing or other roller structure, used to support and slide the upper rail component 1100, improving the smoothness of the upper rail component 1100's sliding within the lower rail component 1200. The side wheel 1140, for example, can also be a rolling bearing or other roller structure, and is used to abut against the lower rail side plate 1220 along the second direction Y, eliminating the gap between the upper rail component 1100 and the lower rail component 1200 along the second direction Y. The support block 1150, for example, can be a rubber block, a plastic block, etc., and is used to abut against the lower rail side plate 1220 along the third direction Z, eliminating the gap between the upper rail component 1100 and the lower rail component 1200 along the third direction Z.

[0056] In this embodiment, the slide rail assembly 100 can be an electric slide rail to improve its automation level. Figures 1-5 The slide rail assembly 100 may also include a power unit 3000.

[0057] The power unit 3000 may include a power generation unit 3100, a drive shaft 3200, a gearbox 3300, and a lead 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 located on the upper side of the upper rail component 1100 and may be connected to the drive shaft 3200. The gearbox 3300 may be installed inside the upper rail component 1100. The input end of the gearbox 3300 may be connected to the drive shaft 3200, and the output end of the gearbox 3300 may be connected to the lead screw 3400. Lead screw supports 3500 are provided at both axial ends of the lead screw 3400, and the lead screw supports 3500 may be connected to the lower rail base plate 1210. With this configuration, when the power generation unit 3100 is started, the power generation 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 the automatic adjustment of the position of the sliding body inside the vehicle.

[0058] It should be understood that the above description of the specific structures of the slide rail unit 1000 and the power unit 3000 in the slide rail assembly 100 is mainly based on the accompanying drawings and should not be construed as limiting the scope of the slide rail assembly 100 provided in this utility model embodiment. In some other implementations of this utility model embodiment, the slide rail assembly 100 may also adopt other structural forms. For example, the slide rail assembly 100 in this application embodiment may also be a manual slide rail, in which case the aforementioned power unit 3000 may not be provided. As 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 example, in the upper rail component 1100, the support block 1150 and the side wheel 1140 can also be combined into a gap-eliminating wheel. The axis direction of the gap-eliminating wheel and the second direction Y can be set at an angle, that is, the gap-eliminating wheel can be set at an inclination, so that the gap-eliminating wheel can simultaneously eliminate the gap between the upper rail component 1100 and the lower rail component 1200 along the second direction Y and the third direction Z, which is also feasible.

[0059] Reference Figure 4 The lower rail component 1200 has an opening P between its two lower rail top plates 1230. When the upper rail component 1100 is installed on the lower rail component 1200, its adapter plate 1120 can extend from the opening P to connect and fix it to the sliding body. The upper rail component 1100 can cover the opening P.

[0060] However, as described in the background section, the length of the lower rail component (i.e., its dimension along the first direction) is usually greater than that of the upper rail component, and in some scenarios, the length of the lower rail component is significantly greater than that of the upper rail component. In other words, the upper rail component can only cover a portion of the opening, while other uncovered openings remain exposed. Thus, under long-term use, foreign objects such as dust and grit can easily enter the lower rail component, affecting the smoothness of the sliding of the upper rail component relative to the lower rail component. Furthermore, these particles may even enter the power unit and damage it.

[0061] To address this, the slide rail assembly provided in this application embodiment may further include a protective unit 2000. This protective unit 2000 can shield the opening P not covered by the upper rail component 1100, thereby reducing the possibility of foreign objects entering the lower rail component 1200 and ensuring smooth sliding of the upper rail component 1100 relative to the lower rail component 1200. In the implementation with a power unit 3000, the possibility of damage to the power unit 3000 can also be reduced.

[0062] The slide rail unit 1000 and the protective unit 2000 can be configured in a one-to-one correspondence, meaning that one slide rail unit 1000 can be paired with one protective unit 2000 for protection. See also Figure 1 When the number of slide rail units 1000 is set to two, the number of 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 Figures 6-8 As shown, and in combination Figure 4 In this embodiment of the application, at least one lower rail top plate 1230 is provided with a guide cavity 1231, and the protective unit 2000 includes a sealing component 2200.

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

[0065] Using the above solution, the slide rail assembly 100 provided in this utility model embodiment 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 move 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 this configuration, the sealing component 2200 can effectively shield the opening P of the lower rail component 1200, which can largely prevent foreign objects from entering the lower rail component 1200 and avoid defects such as poor sliding and abnormal sliding noise in the upper rail component 1100. For the slide rail assembly 100 including the power unit 3000, the above solution can also reduce the damage caused by foreign objects to the power unit 3000, and improve the working stability and service life of the power unit 3000.

[0066] Furthermore, the sealing section 2210A and the two lower rail top plates 1230 are in a sliding fit, and the two lower rail top plates 1230 can guide the sealing section 2210A to slide, which can improve the smoothness of the sliding of the sealing section 2210A. More importantly, the sliding guidance of the sealing section 2210A by the lower rail top plates 1230 also realizes the installation limit of the sealing section 2210A by the lower rail top plates 1230, so that the sealing section 2210A cannot fall into the lower rail component 1200 along the third direction Z. This is of positive significance for ensuring the shielding effect of the sealing section 2210A.

[0067] In addition, the lower rail top plate 1230 is also provided with a guide cavity 1231, in which the spare section 2210C of the flexible sealing strip 2210 can be housed, thereby avoiding the occupation of 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 spare section 2210C to slide, and improve the smoothness of the sliding of the spare section 2210C.

[0068] As can be seen, the protective unit 2000 provided in this embodiment mainly includes a sealing component 2200, with a relatively small number of parts and a simple structural design; moreover, the sealing component 2200 is installed and stored using the lower rail top plate 1230, with a compact structure, high integration, and basically no need to occupy other extra space, and can also meet the requirements of miniaturization design.

[0069] It should be understood that the above-mentioned division of sealing section 2210A, reversing section 2210B, and spare section 2210C is only a distinguishing description based on the setting position of the flexible sealing strip 2210 relative to the lower rail top plate 1230, and does not specifically refer to a particular section of 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 changes, allowing that corresponding section to switch between sealing section 2210A, reversing section 2210B, and spare section 2210C. For example, see... Figure 7 When the upper rail component 1100 moves to the left, the left sealing section 2210A will shorten, causing a portion of the section of the flexible sealing strip 2210 that originally belonged to the left sealing section 2210A to switch to the reversing section 2210B. Meanwhile, 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. During this process, the right sealing section 2210A will lengthen, causing at least a portion of the section of the flexible sealing strip 2210 that originally belonged to the right reversing section 2210B to switch to the sealing section 2210A. At the same time, the section of the flexible sealing strip 2210 that originally belonged to the spare section 2210C will also partially switch 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 sliding groove 2112, and the sealing section 2210A may be slidably connected in the sliding groove 2112.

[0071] Based on the aforementioned groove 2112 configuration, the lower rail top plate 1230 may include two groove sidewalls arranged opposite each other along the third direction Z. The sealing section 2210A may be located within these two groove sidewalls. These sidewalls can partially shield the sealing section 2210A, reducing the portion exposed to the outside. Consequently, this reduces the intrusion of external dust, sand, and other foreign matter into the sealing section 2210A, thus extending its service life and ultimately improving the overall service life of the flexible sealing strip 2210. Furthermore, the lower rail top plate 1230 is a long strip, making it relatively easy to machine the groove 2112 onto it.

[0072] It should be understood that in some other implementations of this utility model, a groove 2112 can be provided in the flexible sealing strip 2210, and then the groove 2112 of the flexible sealing strip 2210 and the lower rail top plate 1230 can be slidably connected, which is also feasible.

[0073] In some implementations, such as Figure 2 and Figure 3As shown, the lower rail top plate 1230, which has a guide cavity 1231, can also be provided with a reversing groove 1233. The reversing groove 1233 can communicate with the guide cavity 1231, and the reversing groove 1233 can be roughly arc-shaped. The reversing section 2210B can be disposed in the reversing groove 1233. The reversing groove 1233 can guide the reversing section 2210B, which can improve the smoothness of the flexible sealing strip 2210 switching between the sealing section 2210A and the spare section 2210C.

[0074] The aforementioned reversing slot 1233 can have an upward-facing slot opening; this implementation method can be found in [reference needed]. Figure 2 and Figure 3 This facilitates the installation of the flexible sealing strip 2210.

[0075] It should be understood that in some other implementations of this utility model, 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 straight cavity shown in the figures. The guide cavity 1231 itself may include a spare cavity and a reversing cavity. The spare cavity may be generally straight, while the reversing cavity may be generally curved. The reversing segment 2210B may be located in the reversing cavity, and the spare segment may be located in the spare cavity. In this case, the sealing segment 2210A and the reversing segment 2210B in the flexible sealing strip 2210 are both equivalent to being provided in 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 sections 2210A, two reversing sections 2210B, and a spare section 2210C.

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

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

[0079] In one specific embodiment, the flexible sealing strip 2210 may include multiple sub-components 2211, with adjacent sub-components 2211 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 form a slot portion 2211C and a groove portion 2211D that communicates with the slot portion 2211C. In specific assembly, the insertion portion 2211A of one sub-component 2211 can be inserted into the slot portion 2211C of another sub-component 2211, and the protrusion 2211B can be engaged in the groove portion 2211D to realize the connection of the two adjacent sub-components 2211. Furthermore, the two adjacent sub-components 2211 can also rotate around the connection between the protrusion 2211B and the groove portion 2211D to realize the rotatable design of the two adjacent sub-components 2211.

[0080] In addition to the above, the flexible sealing strip 2210 can also adopt other structural forms. For example, see [reference needed]. Figure 12 The flexible sealing strip 2210 may also include a transition connector 2212, which may be, for example, a flexible rope, an elastic band, or a bendable strip-shaped part, to accommodate the bending deformation of the flexible sealing strip 2210. Alternatively, when the transition connector 2212 does not need to function as the aforementioned reversing section 2210B, it may also be a rigid strip-shaped component. The transition connector 2212 may connect at least two adjacent sub-components 2210, reducing the number of sub-components 2210 used and thus reducing costs. For example, the flexible sealing strip 2210 may also be an integral structure, such as an integral flexible strip or corrugated pipe made of a material with certain deformation properties, like rubber.

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

[0082] Here, this embodiment of the utility model does not limit the specific structural form of the connecting joint 2220 and the connecting part 1121. In practical applications, those skilled in the art can also make the necessary settings as needed, as long as they meet the requirements of use. For example, the connecting part 1121 can be a first connecting hole, and the connecting joint 2220 can be provided with a second connecting hole 2221. In specific assembly, the first connecting hole and the second connecting hole 2221 can be aligned, and then connected and fixed by means of connecting bolts or the like. As another example, one of the connecting part 1121 and the connecting joint 2220 can adopt a hole-type structure, and the other can be provided with a hook or other form of hanging structure. Then, the connection and fixation of the connecting part 1121 and the connecting joint 2220 can be achieved by the hooking and cooperation of the hanging structure and the hole-type structure.

[0083] In some implementations, the protective unit 2000 may also include a cover plate 2300. The cover plate 2300 may be mounted on the lower rail member 1200, and the cover plate 2300 may specifically be located at at least one end of the lower rail member 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 cover the aforementioned reversing groove 1233, which can reduce the entry of foreign objects such as dust and gravel into the lower rail component 1200, and the resulting problems such as the flexible sealing strip 2210 not moving smoothly.

[0085] Here, this 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 practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use. For example, see [link to relevant documentation]. Figure 14 The cover plate 2300 may include a body portion 2310 and a snap-fit ​​portion 2320. The snap-fit ​​portion 2320 may be located on the lower side of the body portion 2310. The lower rail top plate 1230 may be provided with snap holes, and the cover plate 2300 can be snapped into place through the snap-fit ​​portion 2320 and the snap holes of the lower rail top plate 1230. The body portion 2310 may also be provided with a positioning portion 2330, which, in conjunction with... Figure 2 and Figure 3The lower rail top plate 1230 may also be provided with a positioning hole 1234, into which the positioning part 2330 can be inserted to guide the snap-fit ​​assembly of the cover plate 2300, thereby facilitating the snap-fit ​​fixing of the cover plate 2300. It is understood that in some other implementations of this utility model, the snap-fit ​​part 2320 may be provided on the lower rail top plate 1230, and the snap-fit ​​hole on the cover plate 2300, which is also feasible. For example, the cover plate 2300 and the lower rail top plate 1230 may also be connected and fixed using other connection methods such as welding, riveting, or screw connection.

[0086] Combination Figure 14 A cleaning section 2340 may also be provided on the lower side of the cover plate 2300. The cleaning section 2340 may be a brush or the like. The cleaning section 2340 is used to clean the sealing section 2210A to remove dust, sand and other foreign objects that fall on the upper side of the sealing section 2210A. This can reduce the impact of these foreign objects on the normal sliding of the flexible sealing strip 2210 and can effectively extend the service life of the protective unit 2000.

[0087] Combination Figure 15 and Figure 16 In some other implementations, the cover plate 2300 may also integrate the aforementioned commutation slot 1233. In this case, the commutation section 2210B may be disposed in the commutation slot 1233 of the cover plate 2300.

[0088] In this embodiment, the lower rail component 1200 is made of a rigid material, such as stainless steel. Therefore, the lower rail top plate 1230 has relatively good structural rigidity. During use, the lower rail top plate 1230 is not easily deformed, its installation position can remain unchanged for a relatively long time, and it is not easily affected by external environmental factors such as temperature, allowing the protective unit 2000 to maintain its protective effect for a relatively long period. Furthermore, the rigid material of the lower rail top plate 1230 also has the ability to resist deformation by external forces. Thus, the protective unit 2000 in this embodiment of the present invention also has an anti-trampling effect.

[0089] Example 2

[0090] Please refer to Figure 17 , Figure 17 This is a top view of another slide rail assembly provided by this utility model.

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

[0092] like Figure 17 As shown in this embodiment of the present invention, the flexible sealing strip 2210 may consist of only a sealing section 2210A, a reversing section 2210B, and a spare section 2210C. In this case, 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 these two flexible sealing strips 2210; both lower rail top plates 1230 may be provided with guide cavities 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] This utility model embodiment also provides a sliding module, including a sliding body and a slide rail assembly 100. The slide rail assembly 100 can be the slide rail assembly 100 involved in any of the above-mentioned embodiments one to two. The sliding body can be installed on the slide rail assembly 100 so as to perform sliding assembly through the slide rail assembly 100.

[0095] Here, the present invention does not limit the specific type of the sliding body. In practical applications, those skilled in the art can determine the type based on the specific usage environment. For example, when the sliding module is applied to a vehicle, the sliding body can be a vehicle seat, a sub-dashboard, etc., and the vehicle seat can be any one of the front seat, middle seat, and rear seat.

[0096] Example 4

[0097] This utility model embodiment also provides a vehicle, which may specifically be an electric vehicle, a fuel vehicle, etc., and may include the sliding module in embodiment five.

[0098] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
