[0042] like Figure 1 As shown, an embodiment of the present invention provides a slide rail assembly 1000 that can be used for seats inside a vehicle to drive the seats to move inside the vehicle, thereby conveniently meeting the adjustment requirements of the seats.

[0043] Generally speaking, the above-mentioned slide rail assemblies 1000 exist in pairs, that is, one seat usually needs to be equipped with two slide rail assemblies 1000 to ensure the stability of the seat during installation and adjustment; this implementation method can be seen in Figure 1Of course, the embodiment of the present invention does not limit the number of slide rail assemblies 1000 required for a seat. In actual practice, those skilled in the art can make a selection according to specific needs, as long as it can meet the requirements of use. For example, in some other implementations of the embodiment of the present invention, 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 ease of description, the embodiment of the present invention defines a first direction X, a second direction Y, and a third direction Z, wherein the first direction X refers to the extension direction of the slide rail assembly 1000, and the second direction Y refers to Figure 1 In the direction in which the two slide rail assemblies 1000 are spaced apart, any two of the first direction X, the second direction Y, and the third direction Z may be perpendicular to each other. In some implementations, the first direction X may be the front-rear direction of the vehicle, in which case the second direction Y may be the left-right direction of the vehicle, and the third direction Z may be the up-down direction of the vehicle. Of course, in some other implementations of the embodiments of the present invention, the first direction X and the second direction Y may also be other directions, which are specifically related to the installation position and movable direction of the seat in the vehicle.

[0045] It should be understood that the verticality in the embodiment of the present invention refers to substantially verticality, which allows certain processing errors, assembly errors, etc.

[0046] In the embodiment of the present invention, 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] Combination 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 in the lower rail 1110. Specifically, as Figure 4 As shown, the lower rail 1110 may include a bottom wall 1111 and two lower rail side wall components 1112 . The two lower rail side wall components 1112 may be connected to the bottom wall 1111 . The two lower rail side wall components 1112 and the bottom wall 1111 may 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 distinguishing the description, Figure 4 , Fig. 9 and Fig.10The dividing line P is schematically shown, 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, and in actual application scenarios, there is no component at the dividing line P, and the first space 1113A and the second space 1113B are not isolated from each other; in this way, the overall structure of the lower rail 1110 can be relatively simple, 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, Figure 4 As shown, the lower rail side wall member 1112 may include a lower rail side wall portion 1112A, an inverted portion 1112B and a downwardly turned portion 1112C. The lower rail side wall portion 1112A may be connected to the bottom wall 1111. The inverted portion 1112B may be connected to the lower rail side wall portion 1112A, and the inverted portion 1112B may be located on the inner side of the lower rail side wall portion 1112A, that is, it may be located on the side of the lower rail side wall portion 1112A facing the lower rail space 1113, and the inverted portion 1112B and the bottom wall 1111 may be arranged opposite to each other along the third direction Z. The downwardly turned portion 1112C may be connected to the inverted portion 1112B, and the downwardly turned portion 1112C may extend toward the bottom wall 1111. The lower rail side wall portion 1112A, the inward-folded portion 1112B and the downward-folded portion 1112C can all play a limiting role, which can limit the installation position of the electric upper rail assembly 1200 and the manual upper rail assembly 1300 in the lower rail 1110, and can 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 may specifically be a bolt or a screw, etc., and may include a head 1121 and a rod 1122. The rod 1122 may pass through the bottom wall 1111 and may be connected to the vehicle floor so as to achieve the installation and fixation of the lower rail assembly 1100 and the vehicle floor. After installation, the head 1121 may be closely attached to the bottom wall 1111, and at least a portion 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 through a mounting seat 1240 and a connector in the form of a screw or the like. 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 transmission-connected. 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 realizing the position adjustment of the first seat.

[0052] The manual upper rail assembly 1300 includes a second upper rail member 1310 and a manual lock card 1320. The second upper rail member 1310 is slidably assembled on the lower rail 1110 and is used to connect the second seat. The manual lock card 1320 includes a transmission part 1321 and a locking part 1322. The locking part 1322 is located in the first space 1113A and is spaced from the head 1121 along the third direction Z, and can be located on the side of the head 1121 away from the bottom wall 1111. The transmission part 1321 is slidably assembled on the second upper rail member 1310 along the third direction Z, and can be slid with the second top wall 1311A to control the locking part 1322 and the lower rail 1110 to lock or unlock. In the locked state, the manual upper rail assembly 1300 is in a stationary state relative to the lower rail 1110 to lock the position of 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, thereby realizing the position adjustment of the second seat.

[0053] In the above solution, the head 1121 of the threaded mounting member 1120 is at least partially located in the first space 1113A, and the screw rod 1220 is entirely located in the second space 1113B. In this way, the head 1121 and the screw rod 1220 can be assembled in the lower rail space 1113 in a partitioned manner, which can reduce the installation interference of the head 1121 and the screw rod 1220 and other problems.

[0054] In addition, the slide rail assembly 1000 provided in the embodiment of the present invention is configured with an electric upper rail assembly 1200 and a manual upper rail assembly 1300 at the same time. 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 located on the side of the head 1121 away from the bottom wall 1111, that is, the upper side of the head 1121, so that the redundant space above the head 1121 can be effectively utilized, which can reduce the waste of space and is conducive to improving the integration and compactness of the slide rail assembly 1000.

[0055] More importantly, in the embodiment of the present invention, the manual lock card 1320 and the screw rod 1220 are respectively located in the first space 1113A and the second space 1113B, that is, the manual lock card 1320 and the screw rod 1220 do not interfere with each other in the second direction Y. In this way, the manual upper rail assembly 1300 and the electric upper rail assembly 1200 can overlap in travel, so that the first seat and the second seat can have a larger adjustment range and can better meet the requirements of use.

[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 Figure 2-Figure 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 guide 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 gap eliminating component 1212. The first gap eliminating component 1212 may include a first gap eliminating wheel 1212A and a first gap eliminating bracket 1212B. The first gap eliminating wheel 1212A may specifically be a bearing, etc., which may be mounted on the first gap eliminating bracket 1212B by riveting or other processes. The first gap eliminating bracket 1212B may be connected to the first upper rail 1211 by welding or other processes, and the first gap eliminating bracket 1212B may also be used to improve the structural strength of the first upper rail member 1210.

[0063] Combination Figure 4 The first gap eliminating wheel 1212A can be abutted against the lower rail side wall portion 1112A of the lower rail 1110 to eliminate the gap between the first upper rail component 1210 and the lower rail 1110 in the second direction Y, which can improve the sliding stability of the first upper rail component 1210 in the lower rail 1110 and can effectively eliminate collision noise, etc., which is beneficial to improving product quality.

[0064] The first clearance eliminating bracket 1212B may also be equipped with a first wear-resistant block 1214, which may be made of rubber or other materials. The first wear-resistant block 1214 is used to abut against the inverted portion 1112B of the lower rail 1110 so as 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 in the lower rail 1110, thereby improving the sliding stability of the first upper rail member 1210, and effectively eliminating collision noise, etc., which is conducive to improving the quality of the product.

[0065] It should be understood that the above description of the specific structural form of the first upper rail member 1210 is only a combination of the embodiments of the present invention. Figure 2-Figure 4 The exemplary description provided cannot be used as a limitation on the scope of implementation of the slide rail assembly 1000 provided by the embodiment of the present invention. Under the condition of satisfying the functions, those skilled in the art may also adjust the structural form of the above-mentioned first upper rail component 1210. For example, the first roller 1213A may also be directly installed on the first upper rail 1211 through a roller or the like. For another example, the first wear-resistant block 1214 may also be replaced by a roller structure. For another example, the first clearance eliminating wheel 1212A may also be directly installed on the first upper rail 1211. For another example, the first wear-resistant block 1214 may also be separately configured with a mounting bracket or the like.

[0066] In some optional implementations, such as Figure 3 As shown, the electric drive component 1230 may include an electric drive component 1231 , which may specifically be a motor, etc., and may be installed through an electric drive bracket 1232 .

[0068] The reducer bracket 1233C can be installed on the first upper rail 1211 by welding or other processes, and can be used to improve the structural strength of the first upper rail member 1210. The rubber sleeve 1233B can be installed on the reducer body 1233A, and the reducer body 1233A can be fitted with the rubber sleeve 1233B and the reducer bracket 1233C to a certain extent, so as to improve the installation reliability and stability of the reducer body 1233A in the reducer bracket 1233C. In addition, the reducer body 1233A can also be connected to the reducer bracket 1233C by means of components such as tension pins, so as to further improve the installation reliability of the reducer body 1233A.

[0069] The electric drive component 1230 can be specifically connected by transmission via 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 improve 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 the like.

[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 manner of the embodiment of the present invention, the number of the first connectors 1251 may be two. In other implementation manners of the embodiment of the present invention, the number of the first connectors 1251 may also be other numbers, which is not limited here.

[0072] In some optional implementations, such as Figure 5 , Fig. 9 and Fig.10 As shown, the second upper rail member 1310 may include a second upper rail 1311 , a second clearance 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 spaced apart 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 Fig. 9 with Fig.10 and 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 guide 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. The second clearance eliminating bracket 1312B can be used to enhance the structural strength of the second upper rail member 1310.

[0076] Combined Fig. 9 with Fig.10 and, the second clearance eliminating wheel 1312A can be abutted 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., which is 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. The second wear-resistant block 1314 can be specifically made of rubber or other materials. The second wear-resistant block 1314 is used to abut against the inverted portion 1112B of the lower rail 1110 so as to limit the second upper rail component 1310 in the third direction Z, which can effectively reduce the jumping of the second upper rail component 1310 along the third direction Z when sliding in the lower rail 1110, thereby improving the sliding stability of the second upper rail component 1310, and can effectively eliminate collision noise, etc., which is conducive to improving the quality of the product.

[0078] The second rolling component 1313 may include a second roller 1313A and a second rolling bracket 1313B. The second roller 1313A may be a bearing, etc., which may be mounted on the second rolling bracket 1313B by riveting or other processes. The second rolling bracket 1313B may be mounted on the second upper rail 1311 by welding or other processes, and the second rolling bracket 1313B may 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 a combination of the embodiments of the present invention. Figure 5 , Fig. 9 as well as Fig.10 The exemplary descriptions made by the above cannot be used as a limitation on the scope of implementation of the slide rail assembly 1000 provided by the embodiment of the present invention. Under the condition of satisfying the functions, those skilled in the art may also adjust the structural form of the second upper rail component 1310. For example, the second roller 1313A may also be directly installed on the second upper rail 1311 through a roller, etc. For another example, the second wear-resistant block 1314 may also be replaced by a roller structure. For another example, the second clearance eliminating wheel 1312A may also be directly installed on the second upper rail 1311. For another example, the second wear-resistant block 1314 may also be separately configured with a mounting bracket, etc.

[0080] In some optional implementations, one of the two lower rail side wall members 1112 close to the first space 1113A may be provided with a locking tooth 1112C1, and the locking portion 1322 is used to lock with the locking tooth 1112C1. Figure 9-11 As shown, the locking tooth 1112C1 may be a downwardly turned portion 1112C disposed on the lower rail side wall component 1112 .

[0081] In this way, the locking tooth 1112C1 is arranged relatively far away from the screw rod 1220 in the second direction Y. The cooperation between the locking portion 1322 and the locking tooth 1112C1 can realize unilateral locking of the second upper rail component 1310 and the lower rail 1110, and can avoid interference between the manual lock card 1320 and the screw rod 1220 and the mounting seat 1240, which is of positive significance for ensuring the common rail design of the electric upper rail assembly 1200 and the manual upper rail assembly 1300 in the embodiment of the present invention, as well as stroke overlap.

[0082] In some optional implementations, the locking portion 1322 may be provided with at least one locking hole 1322A1. When the locking hole 1322A1 is inserted into the locking tooth 1112C1, the second upper rail member 1310 and the lower rail 1110 may be locked.

[0083] In actual applications, the transmission part 1321 and the locking part 1322 of the manual lock card 1320 may both include a metal main body part and a plastic shell part. The plastic shell part can be covered on the metal main body part to reduce the collision noise between the manual lock card 1320 and other components during use, thereby improving the quality of the slide rail assembly 1000 provided in the embodiment of the present invention.

[0084] like Figure 6 As shown, the transmission part 1321 may include a first metal body part 1321A and a first plastic shell part 1321B. The first plastic shell part 1321B may be coated on the first metal body part 1321A. The locking part 1322 may include a second metal body part 1322A and a second plastic shell part 1322B. The second plastic shell part 1322B may be coated on the second metal body part 1322A. The second metal body part 1322A may be connected to the first metal body part 1321A, and the specific connection method may be, for example, welding. In addition, the second metal body part 1322A may also be provided with the aforementioned lock hole 1322A1, and the number of the lock hole 1322A1 may not be limited.

[0085] It should be understood that the plastic shell part in the embodiment of the present invention may not cover the entire metal body part. Specifically, the plastic shell part may only cover the local area of ​​the metal body part that is easily collided with other parts. In this way, the covering area of ​​the plastic shell part can be relatively small, the number of plastic shell parts used can be relatively small, and the installation of the plastic shell part can be relatively convenient. For example, for the second metal body part 1322A, the second plastic shell part 1322B can be located only at the bottom of the second metal body part 1322A.

[0086] In some optional implementations, the manual upper rail assembly 1300 may further include an elastic component 1340 , and the elastic component 1340 may be connected to the transmission part 1321 .

[0087] In actual application, when the manual upper rail assembly 1300 needs to be unlocked, 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 be relatively away from the lock tooth 1112C1 for unlocking; in this process, the deformation amount of the elastic component 1340 can be increased, and the elastic component 1340 can accumulate elastic potential energy. When the manual upper rail assembly 1300 needs to be locked, the above-mentioned unlocking driving force can be released. At this time, the elastic potential energy accumulated by the elastic component 1340 can be released to drive the locking part 1322 to move toward the lock tooth 1112C1 until the lock hole 1322A1 of the locking part 1322 can be re-inserted into the lock tooth 1112C1 to complete automatic locking.

[0088] Here, the embodiment of the present invention does not limit the specific type of the elastic component 1340. In practical applications, those skilled in the art can select it according to specific needs, as long as it can meet the requirements of use. Figure 6 In an implementation manner, the elastic component 1340 may be a drawstring, the first metal body portion 1321A may be provided with a hook 1321A1, both ends of the drawstring may be connected to the second top wall 1311A, and the drawstring may also be connected to the hook 1321A1, so as to apply a driving force to the manual lock through the transmission portion 1321. For another example, the elastic component 1340 may also be a linear spring, etc.

[0089] In some optional implementations, the manual upper rail assembly 1300 may further include a guide component 1330, and the guide component 1330 is used to guide the manual lock card 1320, which is beneficial to ensure the stability of the manual lock card 1320 during the displacement process.

[0090] Specifically, Figure 7 and Figure 8 As shown, the guide component 1330 may include a guide side wall 1331 and two guide end walls 1332 connected to each other. The guide side wall 1331 may be arranged opposite to a second upper rail side wall member 1311B in the second direction Y, and the guide side wall 1331 is also provided with a mounting convex plate 1331A, which is used to be connected to the second top wall 1311A, and the specific connection method may be welding, etc. The two guide end walls 1332 may be arranged opposite to each other along the first direction X. The manual lock card 1320 may slide between the guide side wall 1331 and the two guide end walls 1332 to perform sliding guidance.

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

[0092] When the manual lock card 1320 slides along the third direction Z, the guide tooth 1311B4 can be always inserted in the lock hole 1322A1 to guide the displacement of the manual lock card 1320, which can improve the displacement reliability of the manual lock card 1320. In addition, the plug-in cooperation between the guide tooth 1311B4 and the lock hole 1322A1 can also be used to improve the structural strength of the manual lock card 1320, and is conducive to eliminating the gap between the manual lock card 1320 and the second upper rail 1311 in the first direction X, which can reduce the relative sliding of the manual lock card 1320 and the second upper rail 1311, and further improve the locking strength of the manual lock card 1320 and the lower rail 1110.

[0093] The guide teeth 1311B4 can be formed by cutting the second upper rail sidewall portion 1311B1, the second outwardly turned portion 1311B2 and the second upwardly turned portion 1311B3. In this way, the guide teeth 1311B4 are a bent plate structure, and the structural strength of the guide teeth 1311B4 can be high. In practical applications, the guide teeth 1311B4 are not easily damaged by bending, breaking, etc.

[0094] Furthermore, if Figure 7 As shown, one of the two second upper rail side wall components 1311B provided with the guide teeth 1311B4 may include a guide segment 1311B5 and the remaining segments 1311B6. The guide segment 1311B5 and the remaining segments 1311B6 may be arranged along the first direction X, and the guide segment 1311B5 may protrude downward from the remaining segments 1311B6, that is, the size of the guide segment 1311B5 in the third direction Z may be larger than the remaining segments 1311B6. In this way, the structural strength of the guide segment 1311B5 may be relatively high, and even if the guide segment 1311B5 is cut to form the aforementioned guide teeth 1311B4, the guide segment 1311B5 may still have a relatively high strength, which can reduce the situation where the second upper rail side wall component 1311B is damaged during use.

[0095] exist Figure 7 In the implementation mode, both second upper rail side wall components 1311B are provided with guide teeth 1311B4, so that the manual upper rail assembly 1300 can be easily installed in the lower rail assembly 1100. Of course, in actual application, only one of the two second upper rail side wall components 1311B is provided with guide teeth 1311B4 to meet the use requirements.

[0096] The embodiment of the present invention further provides a vehicle, including a seat assembly and at least one slide rail assembly 1000, and the slide rail assembly 1000 may be the slide rail assembly 1000 involved in the aforementioned implementations. Since the aforementioned slide rail assembly 1000 already has the above technical effects, then the vehicle having the slide rail assembly 1000 should also have similar technical effects, so it will not be described in detail here.

[0097] 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.
