[0002] A slide rail assembly for a vehicle seat includes an upper rail, a lower rail, a lead screw and a gear box, etc. Among them, the gear box is connected to the upper rail, and the lead screw is installed in the lower rail. Through the cooperation of the gear box and the lead screw, the relative displacement of the upper rail and the lower rail can be realized.

[0003] Currently, the lower rail is usually connected to the vehicle floor by bolts. To avoid interference between the bolt head and the lead screw, etc., the bolts and the lead screw are basically arranged at intervals along the transverse direction of the vehicle in the lower rail, which results in a large amount of redundant space above the bolt head inside the lower rail that cannot be utilized, and instead increases the installation space occupied by the lead screw slide rail.

[0042] As Figure 1 shown, an embodiment of the present utility model provides a slide rail assembly 1000, which can be used for a seat inside a vehicle to drive the seat to move inside the vehicle, so as to conveniently meet the adjustment requirements of the seat.

[0043] Generally speaking, the above-mentioned slide rail assemblies 1000 exist in pairs. That is, usually two slide rail assemblies 1000 are required for one seat to ensure the stability during the installation and adjustment of the seat; this implementation method can be referred to Figure 1Of course, the embodiments of the present utility model do not limit the number of slide rail assemblies 1000 used for a seat. In specific practice, those skilled in the art can make a choice according to specific needs, as long as the requirements for use can be met. For example, in some other implementation manners of the embodiments of the present utility model, the seat can also be configured with only one slide rail assembly 1000, or can also be configured with three or more slide rail assemblies 1000, etc.

[0044] For the convenience of description, the embodiments of the present utility model define a first direction X, a second direction Y, and a third direction Z. Among them, the first direction X refers to the extending direction of the slide rail assembly 1000, and the second direction Y refers to Figure 1 the direction in which two slide rail assemblies 1000 are spaced apart. Any two of the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. In some implementation manners, the first direction X can be the front-rear direction of the vehicle. At this time, the second direction Y can be the left-right direction of the vehicle, and the third direction Z can be the up-down direction of the vehicle. Of course, in some other implementation manners of the embodiments of the present utility model, the first direction X and the second direction Y can also be other directions, which is specifically related to the installation position and the movable direction of the seat in the vehicle, etc.

[0045] It should be understood that the perpendicularity in the embodiments of the present utility model means substantially perpendicular, and a certain machining error, assembly error, etc. are allowed.

[0046] In the embodiments of the present utility model, a single slide rail assembly 1000 includes a lower rail assembly 1100, an electric upper rail assembly 1200, and a manual upper rail assembly 1300.

[0047] Combined with Figure 2 , the lower rail assembly 1100 includes a lower rail 1110. The lower rail 1110 extends along the first direction X, and a lower rail space 1113 is formed inside the lower rail 1110. Specifically, as Figure 4 shown, the lower rail 1110 can include a bottom wall 1111 and two lower rail side wall members 1112. Both of the two lower rail side wall members 1112 can be connected to the bottom wall 1111, and the two lower rail side wall members 1112 and the bottom wall 1111 can enclose to form the above-mentioned lower rail space 1113.

[0048] The lower rail space 1113 includes a first space 1113A and a second space 1113B arranged along the second direction Y. For the convenience of distinction and description, Figure 4 , Figure 9 and Figure 10Schematically shows a dividing line P, and the first space 1113A and the second space 1113B can be separated by the dividing line P. It should be noted that the dividing line P is a virtual line. In the actual application scenario, there is no component at the dividing line P, and the first space 1113A and the second space 1113B are not isolated; in this way, the overall structural form of the lower rail 1110 can be relatively simple, and the installation interference of other components in the lower rail space 1113 can be relatively small, and the installation process can also be relatively simple.

[0049] More specifically, still as Figure 4 shown, the lower rail side wall member 1112 can include a lower rail side wall portion 1112A, an inwardly turned portion 1112B, and a downwardly turned portion 1112C. The lower rail side wall portion 1112A can be connected to the bottom wall 1111. The inwardly turned portion 1112B can be connected to the lower rail side wall portion 1112A, and the inwardly turned portion 1112B can be located inside the lower rail side wall portion 1112A, that is, it can be located on the side of the lower rail side wall portion 1112A facing the lower rail space 1113, and the inwardly turned portion 1112B and the bottom wall 1111 can be disposed opposite to each other in the third direction Z. The downwardly turned portion 1112C can be connected to the inwardly turned portion 1112B, and the downwardly turned portion 1112C can extend toward the bottom wall 1111. The lower rail side wall portion 1112A, the inwardly turned portion 1112B, and the downwardly turned portion 1112C can all play a limiting role, be able to define the installation positions of the electric upper rail assembly 1200 and the manual upper rail assembly 1300 in the lower rail 1110, and be able to guide the sliding of the electric upper rail assembly 1200 and the manual upper rail assembly 1300 in the lower rail 1110 to a certain extent.

[0050] The lower rail assembly 1100 further includes a threaded mounting member 1120. The threaded mounting member 1120 can specifically be a bolt or a screw, etc., and it can include a head 1121 and a shank 1122. The shank 1122 can pass through the bottom wall 1111 and can be connected to the vehicle floor so as to realize the installation and fixation of the lower rail assembly 1100 and the vehicle floor. After the installation is completed, the head 1121 can be in close contact with the bottom wall 1111, and at least a part of the head 1121 is located in the first space 1113A.

[0051] The electric upper rail assembly 1200 includes a first upper rail component 1210, a screw rod 1220 and an electric drive component 1230. The first upper rail component 1210 is slidably assembled on the lower rail 1110 and is used to connect the first seat. The screw rod 1220 extends along the first direction X and is fixedly installed in the second space 1113B; specifically, the screw rod 1220 is connected to the bottom wall 1111 via a mounting seat 1240 and a connector in the form of a screw. The electric drive component 1230 is connected to the first upper rail component 1210, and the electric drive component 1230 and the screw rod 1220 are in transmission connection. When the electric drive component 1230 is started, the electric drive component 1230 can drive the first upper rail component 1210 to slide along the lower rail 1110 in the first direction X, thereby achieving position adjustment for the first seat.

[0052] The manual upper rail assembly 1300 includes a second upper rail member 1310 and a manual lock 1320. The second upper rail member 1310 is slidably mounted on the lower rail 1110 and is used to connect to the second seat. The manual lock 1320 includes a transmission portion 1321 and a locking portion 1322. The locking portion 1322 is located in the first space 1113A and is spaced apart from the head portion 1121 along the third direction Z. Specifically, it may be located on the side of the head portion 1121 facing away from the bottom wall 1111. The transmission portion 1321 is slidably mounted on the second upper rail member 1310 along the third direction Z, specifically by sliding against the second top wall 1311A, to control the locking portion 1322 and the lower rail 1110 to lock or unlock. In the locked state, the manual upper rail assembly 1300 is stationary relative to the lower rail 1110, thereby locking the second seat. In the unlocked state, the manual upper rail assembly 1300 can slide along the lower rail 1110 in the first direction X to adjust the position of the second seat.

[0053] In the above embodiment, the head 1121 of the threaded mounting member 1120 is at least partially located in the first space 1113A, while the screw rod 1220 is entirely located in the second space 1113B. This allows for the partitioned assembly of the head 1121 and the screw rod 1220 within the lower rail space 1113, thereby reducing installation interference issues between the head 1121 and the screw rod 1220.

[0054] In addition, the slide rail assembly 1000 provided in the embodiment of the present invention is simultaneously equipped with an electric upper rail assembly 1200 and a manual upper rail assembly 1300. The electric upper rail assembly 1200 and the manual upper rail assembly 1300 can share a lower rail 1110, which can realize a common rail design, reduce the number of lower rails 1110 used, and can be easily installed. At the same time, the locking portion 1322 of the manual lock card 1320 in the manual upper rail assembly 1300 can be located in the first space 1113A and on the side of the head 1121 away from the bottom wall 1111, that is, on the upper side of the head 1121, so that the redundant space above the head 1121 can be effectively utilized, which can reduce space waste and help improve the integration and structural compactness of the slide rail assembly 1000.

[0055] More importantly, in this embodiment of the present invention, the manual lock 1320 and the screw 1220 are located in the first space 1113A and the second space 1113B, respectively. In other words, the manual lock 1320 and the screw 1220 do not interfere with each other in the second direction Y. In this way, the manual upper track assembly 1300 and the electric upper track assembly 1200 can overlap in travel, allowing the first and second seats to have a larger adjustment range and better meet user requirements.

[0056] It should be understood that the above-mentioned "overlap in travel" does not mean that the manual upper rail assembly 1300 and the electric upper rail assembly 1200 can be in the same position in the first direction X, but means that the area where the electric upper rail assembly 1200 slides, the manual upper rail assembly 1300 may also slide, and the movement trajectories of the two overlap.

[0057] In some optional implementations, such as Figures 2-4 As shown, the first upper rail member 1210 may include a first upper rail 1211 .

[0058] The first upper rail 1211 can be generally presented in a "ji" shape, including a first top wall 1211A and two first upper rail side wall members 1211B. Both of the two first upper rail side wall members 1211B can be connected to the first top wall 1211A, and the two first upper rail side wall members 1211B can be spaced apart along the second direction Y. The first upper rail side wall member 1211B can include a first upper rail side wall portion 1211B1, a first outward turning portion 1211B2, and a first upward turning portion 1211B3. Specifically, the first upper rail side wall member 1211B can be connected to the first top wall 1211A through the first upper rail side wall portion 1211B1. The first outward turning portion 1211B2 can be connected to the first upper rail side wall portion 1211B1, and the first outward turning portion 1211B2 and the first top wall 1211A can be respectively located on both sides of the first upper rail side wall portion 1211B1 in the second direction Y. The first upward turning portion 1211B3 can be connected to the first outward turning portion 1211B2 and can extend in a direction away from the bottom wall 1111.

[0059] Combined Figure 4 , during specific assembly, the first upward turning portion 1211B3 can be inserted between the downward turning portion 1112C and the lower rail side wall portion 1112A, and the downward turning portion 1112C can be inserted between the first upper rail side wall portion 1211B1 and the first upward turning portion 1211B3, so as to form a limit and guiding between the first upper rail 1211 and the lower rail 1110.

[0060] First rolling members 1213 can be provided at both ends of the first upper rail 1211 in the first direction X. Specifically, the first upper rail 1211 can slide with the bottom wall 1111 through the first rolling members 1213, which can improve the smoothness and stability of the sliding.

[0061] Such as Figure 3 and Figure 4 shown, the first rolling member 1213 can include a first roller 1213A and a first rolling bracket 1213B. The first roller 1213A can specifically be a bearing or the like, and it can be installed on the first rolling bracket 1213B through processes such as riveting. The first rolling bracket 1213B can be connected to the first upper rail 1211 through processes such as welding, and the first rolling bracket 1213B can also improve the structural strength of the first upper rail member 1210.

[0062] The first upper rail 1211 may also be provided with a first backlash elimination component 1212. The first backlash elimination component 1212 may include a first backlash elimination wheel 1212A and a first backlash elimination bracket 1212B. The first backlash elimination wheel 1212A may specifically be a bearing or the like, and it may be installed on the first backlash elimination bracket 1212B through processes such as riveting. The first backlash elimination bracket 1212B may be connected to the first upper rail 1211 through processes such as welding, and the first backlash elimination bracket 1212B can also be used to enhance the structural strength of the first upper rail member 1210.

[0063] Combined with Figure 4 , the first backlash elimination wheel 1212A can abut against the lower rail side wall portion 1112A of the lower rail 1110 to eliminate the gap between the first upper rail member 1210 and the lower rail 1110 in the second direction Y, which can improve the sliding stability of the first upper rail member 1210 within the lower rail 1110, and can effectively eliminate collision noises, etc., which is beneficial to improving the product quality.

[0064] The first backlash elimination bracket 1212B may also be installed with a first wear-resistant block 1214. The first wear-resistant block 1214 may specifically be made of materials such as rubber. The first wear-resistant block 1214 is used to abut against the inwardly turned portion 1112B of the lower rail 1110 to limit the first upper rail member 1210 in the third direction Z, which can effectively reduce the jumping of the first upper rail member 1210 along the third direction Z when sliding within the lower rail 1110, and further improve the sliding stability of the first upper rail member 1210, and can effectively eliminate collision noises, etc., which is beneficial to improving the product quality.

[0065] It should be understood that the above description of the specific structural form of the first upper rail member 1210 is only an exemplary description made in combination with Figures 2-4 the embodiments of the present invention, and it cannot be used as a limitation on the implementation scope of the slide rail assembly 1000 provided by the embodiments of the present invention. Under the condition of meeting the functions, those skilled in the art can also adjust the structural form of the above first upper rail member 1210. For example, the first roller 1213A can also be directly installed on the first upper rail 1211 through a roller shaft or the like. For another example, the first wear-resistant block 1214 can also be replaced with a roller structure. For another example, the first backlash elimination wheel 1212A can also be directly installed on the first upper rail 1211. For another example, the first wear-resistant block 1214 can also be separately configured with a mounting bracket, etc.

[0066] In some alternative implementation manners, as Figure 3 shown, the electric drive member 1230 may include an electric drive component 1231. The electric drive component 1231 may specifically be a motor or the like, and it may be installed through an electric drive bracket 1232.

[0067] The electric drive component 1230 may further include a reducer 1233, which may specifically be a gear box, etc. The reducer 1233 may include a reducer body 1233A, a rubber sleeve 1233B, and a reducer bracket 1233C.

[0068] Reducer bracket 1233C can be mounted to first upper rail 1211 through welding or other processes, and can be used to enhance the structural strength of first upper rail member 1210. Rubber sleeve 1233B can be mounted to reducer body 1233A. Reducer body 1233A can be fitted with rubber sleeve 1233B and reducer bracket 1233C to a certain degree of interference fit, thereby enhancing the installation reliability and stability of reducer body 1233A within reducer bracket 1233C. Furthermore, reducer body 1233A can be connected to reducer bracket 1233C using components such as tension pins to further enhance the installation reliability of reducer body 1233A.

[0069] The electric drive component 1230 can be specifically connected by transmission through the reducer body 1233A and the screw rod 1220.

[0070] The electric upper rail assembly 1200 may further include a first connecting plate 1250, which may be connected to the first upper rail 1211 by welding or other processes to enhance the structural strength of the first upper rail member 1210. The aforementioned electric drive bracket 1232 may be connected to the first connecting plate 1250, and the specific connection method may also be welding or other methods.

[0071] Furthermore, the first connecting plate 1250 may also be provided with a first connecting head 1251, which may specifically be a nut head, etc., and is used to connect to the first seat. Figure 3 In the implementation of the embodiment of the present invention, the number of the first connectors 1251 can be two. In other implementations of the embodiment of the present invention, the number of the first connectors 1251 can also be other, which is not limited here.

[0072] In some optional implementations, such as Figure 5 、 Figure 9 and Figure 10 As shown, the second upper rail member 1310 may include a second upper rail 1311 , a second backlash eliminating component 1312 , a second rolling component 1313 and a second wear-resistant block 1314 .

[0073] The second upper rail 1311 is also basically in a "ji" shape, including a second top wall 1311A and two second upper rail side wall members 1311B. Both of the two second upper rail side wall members 1311B can be connected to the second top wall 1311A, and the two second upper rail side wall members 1311B can be arranged at intervals along the second direction Y. The second upper rail side wall member 1311B can include a second upper rail side wall portion 1311B1, a second outward turning portion 1311B2, and a second upward turning portion 1311B3. Specifically, the second upper rail side wall member 1311B can be connected to the second top wall 1311A through the second upper rail side wall portion 1311B1. The second outward turning portion 1311B2 can be connected to the second upper rail side wall portion 1311B1, and the second outward turning portion 1311B2 and the second top wall 1311A can be respectively located on both sides of the second upper rail side wall portion 1311B1 in the second direction Y. The second upward turning portion 1311B3 can be connected to the second outward turning portion 1311B2 and can extend in a direction away from the bottom wall 1111.

[0074] Combined Figure 9 with Figure 10 During specific assembly, the second upward turning portion 1311B3 can be inserted between the downward turning portion 1112C and the lower rail side wall portion 1112A, and the downward turning portion 1112C can be inserted between the second upper rail side wall portion 1311B1 and the second upward turning portion 1311B3, so as to form a limit and guiding between the second upper rail 1311 and the lower rail 1110.

[0075] The second clearance eliminating member 1312 can include a second clearance eliminating wheel 1312A and a second clearance eliminating bracket 1312B. The second clearance eliminating wheel 1312A can specifically be a bearing or the like, and it can be installed on the second clearance eliminating bracket 1312B through processes such as riveting. The second clearance eliminating bracket 1312B can then be installed on the second upper rail 1311 through processes such as welding, and the second clearance eliminating bracket 1312B can be used to enhance the structural strength of the second upper rail member 1310.

[0076] Combined Figure 9 with Figure 10 The second clearance eliminating wheel 1312A can abut against the lower rail side wall portion 1112A of the lower rail 1110 to eliminate the clearance between the second upper rail member 1310 and the lower rail 1110 in the second direction Y, which can enhance the sliding stability of the second upper rail member 1310 within the lower rail 1110 and can effectively eliminate collision noises, etc., being beneficial to improving the quality of the product.

[0077] The second wear-resistant block 1314 can also be installed on the second clearance-eliminating bracket 1312B. Specifically, the second wear-resistant block 1314 can be made of materials such as rubber. The second wear-resistant block 1314 is used to abut against the inward-turning portion 1112B of the lower rail 1110, so as to limit the second upper rail member 1310 in the third direction Z, which can effectively reduce the jumping of the second upper rail member 1310 in the third direction Z when sliding in the lower rail 1110, and then can improve the sliding stability of the second upper rail member 1310, and can effectively eliminate collision noises, etc., which is beneficial to improving the product quality.

[0078] The second rolling member 1313 can include a second roller 1313A and a second rolling bracket 1313B. Specifically, the second roller 1313A can be a bearing, etc., and it can be installed on the second rolling bracket 1313B through processes such as riveting. The second rolling bracket 1313B can be installed on the second upper rail 1311 through processes such as welding, and the second rolling bracket 1313B can also be used to improve the structural strength of the second upper rail member 1310.

[0079] It should be understood that the above description of the specific structural form of the second upper rail member 1310 is only an exemplary description made in combination with Figure 5 , Figure 9 and Figure 10 etc. of the embodiments of the present invention, and it cannot be used as a limitation on the implementation scope of the slide rail assembly 1000 provided by the embodiments of the present invention. Under the condition of meeting the functions, those skilled in the art can also adjust the structural form of the above second upper rail member 1310. For example, the second roller 1313A can also be directly installed on the second upper rail 1311 through a roller shaft, etc. For another example, the second wear-resistant block 1314 can also be replaced with a roller structure. For another example, the second clearance-eliminating wheel 1312A can also be directly installed on the second upper rail 1311. For another example, the second wear-resistant block 1314 can also be separately configured with a mounting bracket, etc.

[0080] In some alternative implementation manners, one of the two lower rail side wall members 1112 close to the first space 1113A can be provided with a locking tooth 1112C1, and the locking portion 1322 is used to lock with the locking tooth 1112C1. Specifically, as Figures 9-11 shown, the above locking tooth 1112C1 can be provided on the downward-turning portion 1112C of the lower rail side wall member 1112.

[0081] With such a setting, the locking teeth 1112C1 are arranged relatively far from the lead screw 1220 in the second direction Y. The cooperation between the locking portion 1322 and the locking teeth 1112C1 can achieve unilateral locking of the second upper rail member 1310 and the lower rail 1110, which can avoid interference between the manual lock 1320, the lead screw 1220, the mounting seat 1240, etc. It has a positive significance for ensuring the common rail design and stroke overlap of the electric upper rail assembly 1200 and the manual upper rail assembly 1300 in the embodiments of the present invention.

[0082] In some alternative implementation manners, the locking portion 1322 may be provided with at least one locking hole 1322A1. When the locking hole 1322A1 is inserted into the locking teeth 1112C1, the locking between the second upper rail member 1310 and the lower rail 1110 can be achieved.

[0083] In practical applications, both the transmission portion 1321 and the locking portion 1322 of the manual lock 1320 may include a metal body portion and a plastic shell portion. The plastic shell portion may cover the metal body portion to reduce the collision noise between the manual lock 1320 and other components during use, and thus can improve the quality of the slide rail assembly 1000 provided by the embodiments of the present invention.

[0084] As Figure 6 shown, the transmission portion 1321 may include a first metal body portion 1321A and a first plastic shell portion 1321B. The first plastic shell portion 1321B may cover the first metal body portion 1321A. The locking portion 1322 may include a second metal body portion 1322A and a second plastic shell portion 1322B. The second plastic shell portion 1322B may cover the second metal body portion 1322A. The second metal body portion 1322A may be connected to the first metal body portion 1321A. The specific connection manner may be welding, etc. And, the second metal body portion 1322A may also be provided with the aforementioned locking hole 1322A1, and the number of the locking holes 1322A1 may not be limited.

[0085] It should be understood that the covering of the plastic shell portion on the metal body portion in the embodiments of the present invention may not be a full covering. Specifically, the plastic shell portion may only cover the local area of the metal body portion that is likely to collide with other components. In this way, the covering area of the plastic shell portion may be relatively small, the number of the plastic shell portions used may be relatively small, and the installation of the plastic shell portions may be relatively convenient. For example, for the second metal body portion 1322A, the second plastic shell portion 1322B may only be located at the bottom of the second metal body portion 1322A.

[0086] In some alternative implementation manners, the manual upper rail assembly 1300 may further include an elastic member 1340, and the elastic member 1340 may be connected to the transmission portion 1321.

[0087] In practical applications, when it is necessary to unlock the manual upper rail assembly 1300, an unlocking driving force can be applied to the transmission part 1321 through an unlocking rod, a lever, etc., so that the transmission part 1321 can drive the locking part 1322 to move relatively away from the locking tooth 1112C1 for unlocking; during this process, the deformation amount of the elastic member 1340 can increase, and the elastic member 1340 can accumulate elastic potential energy. When it is necessary to lock the manual upper rail assembly 1300, the above unlocking driving force can be released. At this time, the elastic potential energy accumulated by the elastic member 1340 can be released to drive the locking part 1322 to displace toward the locking tooth 1112C1 until the locking hole 1322A1 of the locking part 1322 can be reinserted into the locking tooth 1112C1 to complete automatic locking.

[0088] Here, the embodiments of the present invention do not limit the specific type of the elastic member 1340. In practical applications, those skilled in the art can select according to specific needs as long as it can meet the usage requirements. For example, in Figure 6 one implementation manner, the elastic member 1340 can be a pull rope, and the first metal body part 1321A can be provided with a hook 1321A1. Both ends of the pull rope can be connected to the second top wall 1311A, and at the same time, the pull rope can also be connected to the hook 1321A1 so as to apply a driving force to the manual lock through the transmission part 1321. Another example is that the elastic member 1340 can also be a linear spring, etc.

[0089] In some alternative implementation manners, the manual upper rail assembly 1300 may further include a guiding member 1330, and the guiding member 1330 is used to guide the manual lock 1320, which is beneficial to ensuring the stability of the manual lock 1320 during the displacement process.

[0090] Specifically, as Figure 7 and Figure 8 shown, the guiding member 1330 may include a connected guiding side wall 1331 and two guiding end walls 1332. The guiding side wall 1331 may be disposed opposite to a second upper rail side wall member 1311B in the second direction Y, and the guiding side wall 1331 is further provided with a mounting convex plate 1331A, and the mounting convex plate 1331A is used to connect to the second top wall 1311A. The specific connection manner may be welding, etc. The two guiding end walls 1332 may be disposed opposite to each other along the first direction X. The manual lock 1320 may slide between the guiding side wall 1331 and the two guiding end walls 1332 for sliding guidance.

[0091] In some alternative implementations, at least one of the two second upper rail sidewall members 1311B that is relatively far from the lead screw 1220 in the second direction Y may be provided with a guiding tooth 1311B4, and the guiding tooth 1311B4 may be inserted into the locking hole 1322A1.

[0092] When the manual lock 1320 slides along the third direction Z, the guiding tooth 1311B4 can always be inserted into the locking hole 1322A1 to guide the displacement of the manual lock 1320, thereby improving the displacement reliability of the manual lock 1320. Moreover, the insertion fit between the guiding tooth 1311B4 and the locking hole 1322A1 can also be used to improve the structural strength of the manual lock 1320 and is conducive to eliminating the gap between the manual lock 1320 and the second upper rail 1311 in the first direction X, reducing the situation of relative sliding between the manual lock 1320 and the second upper rail 1311, and further improving the locking strength between the manual lock 1320 and the lower rail 1110.

[0093] The above-mentioned guiding tooth 1311B4 can be specifically formed by cutting the second upper rail sidewall portion 1311B1, the second outward turning portion 1311B2, and the second upward turning portion 1311B3. In this way, the guiding tooth 1311B4 is a bent plate structure, and the structural strength of the guiding tooth 1311B4 can be relatively high. In practical applications, the guiding tooth 1311B4 is not easily bent, broken or damaged.

[0094] Further, as Figure 7 shown, the one of the two second upper rail sidewall members 1311B provided with the guiding tooth 1311B4 may include a guiding section 1311B5 and the remaining section 1311B6. The guiding section 1311B5 and the remaining section 1311B6 may be arranged along the first direction X, and the guiding section 1311B5 may protrude downward from the remaining section 1311B6, that is, the dimension of the guiding section 1311B5 in the third direction Z may be greater than that of the remaining section 1311B6. In this way, the structural strength of the guiding section 1311B5 can be relatively high. Even if the guiding section 1311B5 is cut to form the aforementioned guiding tooth 1311B4, the guiding section 1311B5 can still have relatively high strength, reducing the situation of damage to the second upper rail sidewall member 1311B during use.

[0095] In Figure 7 the implementation, both of the two second upper rail sidewall members 1311B are provided with the guiding tooth 1311B4, which can facilitate the installation of the manual upper rail assembly 1300 in the lower rail assembly 1100. Of course, in practical applications, only one of the two second upper rail sidewall members 1311B being provided with the guiding tooth 1311B4 can meet the usage requirements.

[0096] An embodiment of the present utility model further provides a vehicle, which includes a seat assembly and at least one slide rail assembly 1000. The slide rail assembly 1000 can be the slide rail assembly 1000 involved in the foregoing implementation manners. Since the foregoing slide rail assembly 1000 already has the above technical effects, then the vehicle equipped with the slide rail assembly 1000 should also have similar technical effects, so details are not described herein again.

[0097] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
