[0002] The vehicle seat system includes a seat body and a slide rail assembly. The slide rail assembly is arranged on the lower side of the seat body to support and shift the seat body.

[0003] In the prior art, the slide rail assembly consists of two spaced-apart slide rail assemblies, each comprising an upper rail component and a lower rail component. The two upper rail components are connected by an intermediate bracket, which is equipped with a drive component such as a motor to drive the two upper rail components to move simultaneously. This solution occupies the space under the seat body, encroaching on the vehicle's internal air duct space and failing to meet user requirements for the space under the seat body.

[0004] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an electric slide rail 1000 for installing a seat body inside a vehicle. The electric slide rail 1000 includes a slide rail assembly 1100 and a drive assembly 1200 .

[0034] The slide rail assembly 1100 is installed inside the vehicle and extends as a whole along a first direction X. The slide rail assembly 1100 includes an upper rail component 1110 and a lower rail component 1120, both of which can extend along the first direction X. The upper rail component 1110 is installed on the lower rail component 1120 and can be displaced along the first direction X in the lower rail component 1120.

[0035] The upper rail component 1110 is used to be connected to the seat body.

[0036] Combine Figure 2 and Figure 3The upper rail component 1110 can be connected to a second mounting bracket 1260, specifically by welding, for example. The second mounting bracket 1260 can be located on the upper side of the upper rail component 1110 and can be used to enhance the structural strength of the upper rail component 1110. Furthermore, the second mounting bracket 1260 can be connected to a joint nut 1261, specifically by welding, for example. The joint nut 1261 is used to connect to the seat body.

[0037] The joint nut 1261 can be directly connected to the seat body. Alternatively, the joint nut 1261 can also be indirectly connected to the seat body. Specifically, Figure 1 As shown, the joint nut 1261 can be connected to the seat bracket 2000, and the seat bracket 2000 can be connected to the seat body, so that an indirect connection between the joint nut 1261 and the seat body can be achieved. The seat bracket 2000 is also located on the upper side of the upper rail component 1110.

[0038] In the embodiment of the present invention, the direction in which the upper rail component 1110 and the lower rail component 1120 are arranged relative to each other is defined as a third direction Z. At the same time, a second direction Y is defined, and the second direction Y is the direction in which the multiple electric slide rails 1000 are arranged at intervals in actual applications. Any two of the first direction X, the second direction Y, and the third direction Z can be set at an angle. For the vehicle, the actual meaning represented by the first direction X, the second direction Y, and the third direction Z is not limited here. This is specifically related to the displacement requirements of the seat body inside the vehicle. In a specific scenario, the first direction X can be the front-to-back direction of the vehicle, so that the seat body can be displaced in the front-to-back direction; the second direction Y can be the left-to-right direction of the vehicle; and the third direction Z can be the up-down direction of the vehicle. The first direction X, the second direction Y, and the third direction Z can all be perpendicular to each other.

[0039] The lower rail member 1120 is used to be connected to the vehicle floor.

[0040] Specifically, if Figure 2 As shown, the lower rail component 1120 can be connected to the vehicle floor via a first connecting member 1121. The first connecting member 1121 can be a screw or a bolt, etc., including a stem and a head. The head can be located on the inner side of the lower rail component 1120, and the stem can pass through the lower rail component 1120 and can be connected to the vehicle floor.

[0041] The driving assembly 1200 includes a rotation driving component 1210 , a first transmission component 1220 , a second transmission component 1230 and a screw component 1240 .

[0042] The screw component 1240 is installed in the lower rail component 1120 .

[0043] Specifically, if Figure 2 As shown, the screw rod component 1240 may include a screw rod body 1241, a screw rod seat 1242, a plug nut 1243 and a second connecting member 1244. The number of the screw rod seats 1242 can be two, and the two screw rod seats 1242 can be respectively arranged at the axial ends of the screw rod body 1241. Of the two screw rod seats 1242, one can be connected to the screw rod body 1241 by welding or the like, and the other can be fixed to the screw rod body 1241 by the plug nut 1243 to facilitate disassembly and assembly. Both screw rod seats 1242 can be connected to the lower rail component 1120 by the second connecting member 1244, and the second connecting member 1244 can specifically be a screw or the like.

[0044] During assembly, the projection of the central axis of the screw body 1241 along the third direction Z (a line segment) and the projection of the central axis of the first connecting member 1121 along the third direction Z (a point) can be spaced apart along the second direction Y, so that the first connecting member 1121 and the screw body 1241 can be assembled with a certain degree of offset in the second direction Y. In this way, the internal space of the lower rail component 1120 can be more reasonably utilized, and interference between the screw component 1240 and the head of the first connecting member 1121 during installation can be reduced. At the same time, interference between other components and the head of the first connecting member 1121 during displacement along the screw component 1240 can also be reduced.

[0045] The second transmission component 1230 is installed in the upper rail component 1110, and the second transmission component 1230 is threadedly connected to the screw component 1240. In other words, the second transmission component 1230 can be displaced along the screw component 1240, thereby driving the upper rail component 1110 to displace within the lower rail component 1120. The first transmission component 1220 includes a first housing 1221, a first input shaft 1222, and a first output shaft 1223. The first housing 1221 and the driving component 1210 are both located outside the slide rail assembly 1100 to reduce the internal space occupied by the upper rail component 1110. The driving component 1210 can specifically be a motor, which can be in transmission connection with the first input shaft 1222 to drive the first input shaft 1222 to rotate. The first input shaft 1222 and the first output shaft 1223 are in transmission connection to drive the first output shaft 1223 to rotate. The first input shaft 1222 and the first output shaft 1223 are spaced apart along the second direction Y. The first output shaft 1223 is partially inserted into the upper rail component 1110 and is in transmission connection with the second transmission component 1230 .

[0046] In the embodiment of the present invention, the slide rail assembly 1100 of the electric slide rail 1000 is separately configured with a drive assembly 1200, rather than adopting the solution of the related art in which two slide rail assemblies share a drive assembly. In this way, when the electric slide rail 1000 provided by the embodiment of the present invention is used in a specific application, the space between two adjacent electric slide rails 1000 can be released, so that there can be more abundant space under the seat body. This space can be used as an air duct to improve the ventilation performance of the vehicle. Alternatively, this space can also be used as a storage space to meet the user's storage needs, etc. In short, the existence of this space allows the vehicle to have more design possibilities under the seat body, which can enrich the vehicle functions to a greater extent and enhance the user experience.

[0047] More importantly, in the embodiment of the present invention, the first input shaft 1222 and the first output shaft 1223 are spaced apart in the second direction Y. This allows the rotating component 1210 to have a certain degree of eccentricity relative to the upper rail component 1110, allowing the rotating component 1210 to avoid the upper side of the upper rail component 1110 to a certain extent. This allows the rotating component 1210 to effectively avoid existing components on the upper side of the upper rail component 1110 (such as the aforementioned seat bracket 2000), thereby ensuring that the electric slide rail 1000 provided by the embodiment of the present invention can be successfully used.

[0048] In particular, the solution provided by the present invention can be applied to the modification of related vehicle seat systems. During modification, only the intermediate bracket connecting the two upper rail components and the motor need to be removed, while the relevant structures on the seat body (such as the aforementioned seat bracket 2000) can be removed with less effort. This can reduce the difficulty and cost of the modification, further facilitating the widespread application of the present invention.

[0049] In other words, the electric slide rail 1000 involved in the embodiments of the present invention can have the above-mentioned structure when the device leaves the factory, or it can be obtained by modifying an existing vehicle seat system in the related art. In short, regardless of the method used, as long as it is consistent with the structural design of the electric slide rail 1000 provided in the embodiments of the present invention, it shall fall within the scope of protection of the embodiments of the present invention.

[0050] In some optional implementations, the drive assembly 1200 may further include a first mounting bracket 1250. Figure 3 As shown, the first mounting bracket 1250 may include a first plate portion 1251 and a second plate portion 1252 that are arranged at an angle, and the angle may be, for example, 90 degrees.

[0051] The first plate portion 1251 can be connected to the upper rail member 1110 to enhance the structural strength of the upper rail member 1110. The first plate portion 1251 can be directly connected to the upper rail member 1110. Alternatively, the first plate portion 1251 can be connected to the aforementioned second mounting bracket 1260, and then indirectly connected to the upper rail member 1110 via the second mounting bracket 1260. In fact, the first mounting bracket 1250 and the second mounting bracket 1260 can also be a one-piece structure, which can make equipment processing and assembly relatively simple.

[0052] The second plate portion 1252 can be located on one side of the first plate portion 1251 in the second direction Y to avoid the space above the upper rail member 1110. The first housing 1221 can be mounted on the second plate portion 1252, for example, by screw connection, clamping, riveting, etc. After installation, the first housing 1221 can be located above the second plate portion 1252.

[0053] In some optional implementations, such as Figure 4 As shown, the first housing 1221 may be a split structure, including two first shell plates 1221A. The two first shell plates 1221A may be arranged relative to each other along a third direction Z, or the two first shell plates 1221A may be arranged relative to each other along other directions, which is not specifically limited here.

[0054] The first transmission component 1220 may further include a first input gear 1224 and a first output gear 1225. The first input gear 1224 and the first output gear 1225 may be disposed between the two first shell plates 1221A. The first input gear 1224 may be connected to the first input shaft 1222, and the first output gear 1225 may be connected to the first output shaft 1223. The first input gear 1224 may mesh with the first output gear 1225 to achieve power transmission between the first input shaft 1222 and the first output shaft 1223. The gear transmission has high reliability and a fast response speed, enabling rapid and reliable driving or locking of the upper rail component 1110.

[0055] The first input gear 1224 can be directly meshed with the first output gear 1225. In this way, the connection structure between the first input shaft 1222 and the first output shaft 1223 can be relatively simple.

[0056] Alternatively, the first input gear 1224 may be indirectly meshed with the first output gear 1225, that is, another transmission gear may be provided between the two to facilitate adjustment of the rotation speed and rotation direction of the first output shaft 1223. Figure 4As shown, an intermediate gear 1227 may be disposed between the first input gear 1224 and the first output gear 1225. This intermediate gear 1227 can adjust the transmission ratio between the first output gear 1225 and the first input gear 1224, and also enable the first output gear 1225 and the first input gear 1224 to rotate in the same direction. Bearing sleeves 1226 may be disposed on the axial ends of the first input gear 1224, the first output gear 1225, and the intermediate gear 1227 to enhance smooth rotation of the gears. Furthermore, each bearing sleeve 1226 may be self-lubricating to reduce wear, noise, and vibration, thereby enhancing the user experience.

[0057] It should be understood that the transmission structure between the first input shaft 1222 and the first output shaft 1223 is not limited to the above-mentioned gear transmission. In actual applications, other transmission methods such as pulleys and sprockets can also be used for transmission between the two, as long as the first input shaft 1222 can ultimately drive the first output shaft 1223 to rotate.

[0058] In some optional implementations, such as Figure 3 As shown, the second transmission component 1230 may include a second housing 1231 and a third mounting bracket 1232 .

[0059] The third mounting bracket 1232 can be mounted on the upper rail member 1110. Specific mounting methods include welding, clamping, screw connection, riveting, etc. The third mounting bracket 1232 can be used to enhance the structural strength of the upper rail member 1110. The second housing 1231 can be mounted on the third mounting bracket 1232, thereby achieving an indirect connection between the second housing 1231 and the third mounting bracket 1232. Of course, in some other implementations of the present invention, the second housing 1231 can also be directly connected to the upper rail member 1110.

[0060] Furthermore, the second transmission component 1230 may further include a buffer component 1233 .

[0061] The buffer component 1233 can specifically be an elastomer made of a material with a certain degree of elastic deformation, such as rubber, latex, or silicone. The buffer component 1233 can be located between the second housing 1231 and the third mounting bracket 1232. On the one hand, it can indirectly achieve an interference fit between the second housing 1231 and the third mounting bracket 1232, which can greatly improve the connection reliability between the second housing 1231 and the third mounting bracket 1232. On the other hand, it can also buffer vibrations between the second housing 1231 and the third mounting bracket 1232, effectively eliminating vibration noise, thereby improving the user experience.

[0062] The specific structure and quantity of the buffer component 1233 are not limited here. In practical applications, those skilled in the art can select according to specific needs, as long as they can meet the requirements of use. Figure 3 As shown, the buffer component 1233 can be roughly U-shaped and can cover three surfaces of the second shell 1231.

[0063] In some optional implementations, such as Figure 5 As shown, the second housing 1231 may be a split structure, including two second housing plates 1231A. The two second housing plates 1231A may be arranged relative to each other along a third direction Z, or may be arranged relative to each other along other directions, which is not specifically limited here.

[0064] The second transmission component 1230 may further include a second input gear 1234 and a second output gear 1235. The second input gear 1234 and the second output gear 1235 may be disposed between the two second shell plates 1231A. The second input gear 1234 may be mounted on the first output shaft 1223. The second input gear 1234 and the second output gear 1235 may mesh with each other to achieve power transmission between the second input gear 1234 and the second output gear 1235. This gear transmission has high reliability and fast response speed, allowing for quick and reliable driving or locking of the upper rail component 1110.

[0065] The second output gear 1235 and the second input gear 1234 can be directly meshed with each other, in which case the connection structure between the two can be relatively simple. Of course, the second output gear 1235 and the second input gear 1234 can also be indirectly meshed with each other, in which case another transmission gear can be provided between them to adjust the rotation speed and rotation direction of the second output gear 1235.

[0066] Specifically, if Figure 5 As shown, the second output gear 1235 and the second input gear 1234 can be directly meshed, and the axial direction of the second output gear 1235 and the axial direction of the second input gear 1234 can be arranged at an angle. In this case, one of the second input gear 1234 and the second output gear 1235 can adopt a worm gear structure, and the other can adopt a worm structure; alternatively, the second input gear 1234 and the second output gear 1235 can both be configured as bevel gears, etc.

[0067] The second output gear 1235 may have an internal thread, and the second output gear 1235 may be threadedly connected to the screw component 1240 , specifically, may be threadedly connected to the screw body 1241 in the screw component 1240 .

[0068] A bearing 1236 and a bushing 1237 may be provided at both axial ends of the second output gear 1235. The bearing 1236 may be a thrust bearing or the like, and is used to axially position the second output gear 1235, thereby improving the connection reliability and rotation smoothness of the second output gear 1235.

[0069] In some optional implementations, the upper rail component 1110 may also be provided with a rolling component 1140 and a gap eliminating component 1130 .

[0070] There may be two rolling members 1140 , which may be located at two ends of the upper rail member 1110 in the first direction X. The upper rail member 1110 may slide via the rolling members 1140 and the bottom wall of the lower rail member 1120 , thereby improving the smoothness and stability of the sliding.

[0071] like Figure 3 As shown, rolling member 1140 may include a roller 1142 and a second mounting bracket 1141. Roller 1142 may be a bearing, etc., and may be mounted to second mounting bracket 1141 via riveting or other processes. Second mounting bracket 1141 may be connected to upper rail member 1110 via welding or other processes, further enhancing the structural strength of upper rail member 1110.

[0072] The gap eliminating component 1130 may include a gap eliminating wheel 1132 and a first mounting frame 1131. The gap eliminating wheel 1132 may specifically be a bearing, etc., which may be mounted on the first mounting frame 1131 by riveting or other processes. The first mounting frame 1131 may be connected to the upper rail component 1110 by welding or other processes, and the first mounting frame 1131 may also be used to improve the structural strength of the upper rail component 1110. The gap eliminating wheel 1132 may abut against the inner wall surface of the lower rail component 1120 to eliminate the gap between the upper rail component 1110 and the lower rail component 1120 in the second direction Y, thereby improving the sliding stability of the upper rail component 1110 within the lower rail component 1120 and effectively eliminating collision noise, etc., which is beneficial to improving the quality of the product.

[0073] The first mounting frame 1131 may also be equipped with a wear-resistant block 1133, which may be made of a material such as rubber. The wear-resistant block 1133 is also used to abut against the inner wall surface of the lower rail component 1120 so as to limit the upper rail component 1110 in the third direction Z. This can effectively reduce the jumping of the upper rail component 1110 along the third direction Z when sliding in the lower rail component 1120, thereby improving the sliding stability of the upper rail component 1110 and effectively eliminating collision noise, etc., which is conducive to improving product quality.

[0074] It should be understood that the above description of the specific structural forms of the rolling component 1140 and the clearance eliminating component 1130 is only a combination of the embodiments of the present invention. Figure 3 The exemplary description provided here cannot be used as a limitation on the scope of implementation of the electric slide rail 1000 provided by the embodiment of the utility model. Under the condition that the functions are met, those skilled in the art can also adjust the structural forms of the above-mentioned rolling component 1140 and the gap elimination component 1130. For example, the roller 1142 can also be directly installed on the upper rail component 1110 through a roller, etc. For another example, the wear-resistant block 1133 can also be replaced with a roller structure. For another example, the gap elimination wheel 1132 can also be directly installed on the upper rail component 1110. For another example, the wear-resistant block 1133 can also be separately configured with a mounting bracket, etc.

[0075] In some optional implementations, at least one of the first input shaft 1222 and the first output shaft 1223 is a flexible shaft. The flexible shaft's deformability facilitates installation, effectively absorbs installation tolerances, and reduces noise caused by vibration, thereby improving product quality and, in turn, enhancing the user experience.

[0076] In practical applications, the first input shaft 1222 and the first output shaft 1223 can both be configured as flexible shafts, or one of them can be configured as a flexible shaft, or both can be configured as rigid shafts, which is not explicitly limited here.

[0077] Please refer to Figure 6 , Figure 6 This is a schematic structural diagram of the electric slide rail assembly provided in an embodiment of the present utility model.

[0078] An embodiment of the present invention provides a slide rail assembly, including a plurality of electric slide rails 1000 . The electric slide rails 1000 may be arranged at intervals along the second direction Y, and the electric slide rails 1000 are all electric slide rails 1000 involved in the aforementioned implementations.

[0079] like Figure 6 As shown, the electric slide rails 1000 involved in the aforementioned implementation methods can be used to make each electric slide rail 1000 independent of each other, and the space between two adjacent electric slide rails 1000 can be released. This part of the space can be used as an air duct or for storage, etc. In short, it can make the interior of the vehicle have more spare space, add more possibilities to the design of the vehicle seat system, and can greatly enhance the user experience.

[0080] Combined with the aforementioned Figure 1For each electric slide rail 1000, a seat bracket 2000 can be further provided on the upper side of its upper rail component 1110, and the driving component 1210 of the electric slide rail 1000 can be located on the side of the seat bracket 2000 in the second direction Y so as to avoid the seat bracket 2000, so that the electric slide rail 1000 provided by the embodiment of the present invention can be better applied, especially can be adapted to the modification of the existing vehicle seat system in the related technology, can reduce the removal of components in the existing vehicle seat system, and thus can reduce the modification difficulty and modification cost, which is more conducive to the promotion and application of the electric slide rail 1000 provided by the embodiment of the present invention in the market.

[0081] The above is only a preferred embodiment 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 within the scope of protection of the present invention.
