In this solution, the space under the seat body will be occupied, which will infringe on the air duct space inside the vehicle, and cannot meet the user's requirements for utilizing 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. Summary of the invention

[0032] Please refer to Figure 1-Figure 5 , Figure 1 A diagram showing the connection structure of the electric slide rail and the seat bracket provided in an embodiment of the present invention; Figure 2 This is an exploded view of the electric slide; Figure 3 It is a connection structure diagram of the upper rail component, the second transmission component, the clearance eliminating component, the rolling component, the first mounting bracket and the second mounting bracket in an embodiment of the present invention; Figure 4 is an internal exploded view of the first housing; Figure 5 It is an exploded view of the second transmission component and the lead screw.

[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 the first direction X. The slide rail assembly 1100 includes an upper rail component 1110 and a lower rail component 1120, and both the upper rail component 1110 and the lower rail component 1120 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] Combination Figure 2 and Figure 3 The upper rail component 1110 may be connected to a second mounting bracket 1260, and the specific connection method may be welding, etc. The second mounting bracket 1260 may be located on the upper side of the upper rail component 1110, and may be used to improve the structural strength of the upper rail component 1110. In addition, the second mounting bracket 1260 may also be connected to a joint nut 1261, and the specific connection method may be welding, etc. 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 the joint nut 1261 and the seat body can be indirectly connected. 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 relatively arranged 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 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 true meaning represented by the first direction X, the second direction Y, and the third direction Z is not limited here, which 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 and rear direction of the vehicle, so that the seat body can be displaced in the front and rear direction; the second direction Y can be the left and right direction of the vehicle; the third direction Z can be the up and 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, Figure 2 As shown, the lower rail component 1120 can be connected to the vehicle floor through a first connecting member 1121. The first connecting member 1121 can be a screw or a bolt, etc., including a rod and a head, the head can be located on the inner side of the lower rail component 1120, and the rod 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 rod component 1240 is installed in the lower rail component 1120 .

[0043] Specifically, Figure 2As 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 screw rod seats 1242 may be two, and the two screw rod seats 1242 may be respectively arranged at the axial ends of the screw rod body 1241. Of the two screw rod seats 1242, one may be connected to the screw rod body 1241 by welding or the like, and the other may be fixed to the screw rod body 1241 by the plug nut 1243 to facilitate disassembly and assembly. Both screw rod seats 1242 may be connected to the lower rail component 1120 by the second connecting member 1244, and the second connecting member 1244 may 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 arranged at intervals along the second direction Y, so that the first connecting member 1121 and the screw body 1241 can form a certain offset assembly in the second direction Y. In this way, the internal space of the lower rail component 1120 can be more reasonably utilized, and the interference between the screw component 1240 and the head of the first connecting member 1121 during the installation process can be reduced. At the same time, the interference between other components and the head of the first connecting member 1121 during the displacement of 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, that is, the second transmission component 1230 can be displaced along the screw component 1240, and then the upper rail component 1110 can be driven to displace in 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 occupation of the internal space of the upper rail component 1110. The driving component 1210 can be specifically a motor, which can be connected to the first input shaft 1222 for driving the first input shaft 1222 to rotate. The first input shaft 1222 and the first output shaft 1223 are connected to drive the first output shaft 1223 to rotate. The first input shaft 1222 and the first output shaft 1223 are arranged at intervals along the second direction Y. The first output shaft 1223 is partially inserted into the upper rail component 1110 and is transmission-connected to the second transmission component 1230 .

[0046] In an embodiment of the present invention, the slide rail assembly 1100 of the electric slide rail 1000 is separately configured with a drive assembly 1200, instead of adopting the solution of two slide rail assemblies sharing a drive assembly in the related art. 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. The space can be used as an airway to improve the ventilation performance of the vehicle. Alternatively, the space can also be used as a storage space to meet the storage needs of users, 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 improve the user experience.

[0047] More importantly, the first input shaft 1222 and the first output shaft 1223 in the embodiment of the present invention are spaced apart in the second direction Y. In this way, the rotation driving component 1210 can have a certain eccentricity relative to the upper rail component 1110, so that the rotation driving component 1210 can avoid the upper side of the upper rail component 1110 to a certain extent, so that the rotation driving component 1210 can better avoid the existing components on the upper side of the upper rail component 1110 (such as the aforementioned seat bracket 2000), so as to ensure that the electric slide rail 1000 provided by the embodiment of the present invention can be smoothly applied.

[0048] In particular, the solution provided by the embodiment of the present invention can be applied to the modification of the vehicle seat system in the related art. During the specific modification, only the middle bracket and the motor connecting the two upper rail components need to be removed, while the related structures on the seat body side (such as the aforementioned seat bracket 2000) can be removed less, which can reduce the difficulty of the modification and the cost of the modification, which is more conducive to the promotion and application of the embodiment of the present invention.

[0049] In other words, the electric slide rail 1000 involved in the embodiment of the present invention can have the above-mentioned structural form when the device leaves the factory, or can be obtained by modifying the existing vehicle seat system in the related art. In short, no matter how it is obtained, as long as it is consistent with the structural design of the electric slide rail 1000 provided in the embodiment of the present invention, it should fall within the protection scope of the embodiment 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 component 1110, and can be used to improve the structural strength of the upper rail component 1110. The first plate portion 1251 can be directly connected to the upper rail component 1110. Alternatively, the first plate portion 1251 can also be connected to the aforementioned second mounting bracket 1260, and then indirectly connected to the upper rail component 1110 through the second mounting bracket 1260. In fact, the first mounting bracket 1250 and the second mounting bracket 1260 can also be an integrated structure formed in one piece, so that the equipment processing and assembly can be relatively simple.

[0052] The second plate portion 1252 may be located on one side of the first plate portion 1251 in the second direction Y to avoid the space on the upper side of the upper rail member 1110. The first housing 1221 may be installed on the second plate portion 1252, and the specific installation method may be, for example, screw connection, clamping, riveting, etc. After installation, the first housing 1221 may be located on the upper side of 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 housing plates 1221A. The two first housing plates 1221A may be arranged relative to each other along a third direction Z, or the two first housing plates 1221A may be arranged relative to each other along other directions, which is not explicitly limited here.

[0054] The first transmission component 1220 may further include a first input gear 1224 and a first output gear 1225, and 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 a high reliability and a fast response speed, and the upper rail component 1110 may be driven or locked quickly and reliably.

[0055] The first input gear 1224 may 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 may be relatively simple.

[0056] Alternatively, the first input gear 1224 may also be indirectly meshed with the first output gear 1225, that is, other transmission gears may be provided between the two to facilitate adjusting the rotation speed and rotation direction of the first output shaft 1223. Figure 4As shown, an intermediate gear 1227 may be provided between the first input gear 1224 and the first output gear 1225. The intermediate gear 1227 may adjust the transmission ratio between the first output gear 1225 and the first input gear 1224, and may also make the first output gear 1225 and the first input gear 1224 rotate in the same direction. The axial ends of the first input gear 1224, the first output gear 1225 and the intermediate gear 1227 may be provided with bearing sleeves 1226 to improve the smoothness of the rotation of each gear; and each bearing sleeve 1226 may also have self-lubricating properties to reduce wear, which is conducive to reducing noise and vibration, and can better improve 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 practical 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 component 1110, and the specific mounting method can be, for example, welding, clamping, screw connection, riveting, etc. The third mounting bracket 1232 can be used to improve the structural strength of the upper rail component 1110. The second housing 1231 can be mounted on the third mounting bracket 1232, so that the second housing 1231 and the third mounting bracket 1232 can be indirectly connected. Of course, in some other implementations of the embodiments of the present invention, the second housing 1231 can also be directly connected to the upper rail component 1110.

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

[0061] The buffer component 1233 may specifically be an elastomer made of a material having a certain elastic deformation ability, such as rubber, latex, or silicone. The buffer component 1233 may be located between the second shell 1231 and the third mounting bracket 1232. On the one hand, the interference fit between the second shell 1231 and the third mounting bracket 1232 may be indirectly realized, which can improve the connection reliability between the second shell 1231 and the third mounting bracket 1232 to a greater extent. On the other hand, the vibration between the second shell 1231 and the third mounting bracket 1232 may also be buffered to effectively eliminate 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 the two second housing plates 1231A may be arranged relative to each other along other directions, which is not explicitly limited here.

[0064] The second transmission component 1230 may further include a second input gear 1234 and a second output gear 1235, and 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. The gear transmission has a high reliability and a fast response speed, and the upper rail component 1110 may be driven or locked quickly and reliably.

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

[0066] Specifically, Figure 5 As shown, the second output gear 1235 and the second input gear 1234 may be directly meshed, and the axial direction of the second output gear 1235 and the axial direction of the second input gear 1234 may be arranged at an angle. At this time, one of the second input gear 1234 and the second output gear 1235 may adopt a worm gear structure, and the other may adopt a worm gear structure; or the second input gear 1234 and the second output gear 1235 may 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 , and 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, etc., for axially positioning the second output gear 1235, and is conducive to 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] The number of the rolling parts 1140 may be two, and the two rolling parts 1140 may be respectively located at two ends of the upper rail part 1110 in the first direction X. The upper rail part 1110 may specifically slide through the rolling parts 1140 and the bottom wall of the lower rail part 1120, which can improve the smoothness and stability of the sliding.

[0071] like Figure 3 As shown, the rolling component 1140 may include a roller 1142 and a second mounting frame 1141. The roller 1142 may be a bearing, etc., which may be mounted on the second mounting frame 1141 by riveting or other processes. The second mounting frame 1141 may be connected to the upper rail component 1110 by welding or other processes, and the second mounting frame 1141 may also improve the structural strength of the upper rail component 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, which may improve the sliding stability of the upper rail component 1110 in the lower rail component 1120, and may effectively eliminate 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 rubber or other materials. 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, which 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 the quality of the product.

[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 cannot be used as a limitation on the scope of implementation of the electric slide rail 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 forms of the rolling component 1140 and the clearance eliminating component 1130. For example, the roller 1142 may also be directly mounted on the upper rail component 1110 through a roller or the like. For another example, the wear-resistant block 1133 may also be replaced by a roller structure. For another example, the clearance eliminating wheel 1132 may also be directly mounted on the upper rail component 1110. For another example, the wear-resistant block 1133 may also be separately configured with a mounting bracket or the like.

[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 is deformable, so that it is easy to install, can better absorb installation tolerances, and can reduce noise caused by vibration, which can improve product quality and thus improve 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 of them can be configured as rigid shafts, which is not explicitly limited here.

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

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

[0079] like Figure 6 As shown, the electric slide rails 1000 involved in the aforementioned implementation methods are adopted, so that each electric slide rail 1000 can be 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 more spare space inside the vehicle, add more possibilities to the design of the vehicle seat system, and can greatly enhance the user experience.

[0080] Combined with the above Figure 1For each electric slide rail 1000, a seat bracket 2000 may be further provided on the upper side of its upper rail component 1110, and the driving component 1210 of the electric slide rail 1000 may be located on one 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 in 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 in the embodiment of the present invention in the market.

[0081] 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.
