Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to an electric slide rail assembly, an electric slide rail system, and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, the demand for vehicle comfort and intelligence continues to grow, and the application of electric sliding rail components in vehicle interiors is gradually increasing.

[0003] The electric slide rail assembly includes an upper rail component, a lower rail component, and an electric drive component. The upper rail component can move along the lower rail component under the drive of the electric drive component. However, in related technologies, when the upper rail component moves within the lower rail component, it is prone to wobbling relative to the lower rail component, resulting in poor operational stability of the upper rail component and potentially causing abnormal noise and significant impact on the user experience.

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

[0005] The purpose of this utility model is to provide an electric slide rail assembly, an electric slide rail system, and a vehicle. The electric slide rail assembly has relatively good operational stability and relatively low noise, which helps to improve the user experience.

[0006] To solve the above-mentioned technical problems, this utility model provides an electric slide rail assembly, including an upper rail component and a lower rail component. The upper rail component is assembled on the lower rail component. The lower rail component includes a lower rail bottom wall, two lower rail side walls, and two lower rail top walls. The upper rail component includes an upper rail body and a gap-eliminating mechanism. The gap-eliminating mechanism is installed on the upper rail body and includes a horizontal gap-eliminating component and a vertical gap-eliminating component. The horizontal gap-eliminating component includes a first sliding element that contacts the lower rail side wall in the horizontal direction. The vertical gap-eliminating component includes a second sliding element and a rolling element. The rolling element contacts the lower rail bottom wall in the vertical direction, and the second sliding element contacts the lower rail top wall in the vertical direction.

[0007] In this embodiment of the invention, the upper rail component is equipped with a gap-eliminating mechanism, which includes a transverse gap-eliminating component and a vertical gap-eliminating component. The transverse gap-eliminating component includes a first sliding element that contacts the lower rail sidewall in the transverse direction, and can be used to eliminate the gap between the upper rail body and the lower rail component in the transverse direction. The vertical gap-eliminating component includes a second sliding element and a rolling element; the second sliding element contacts the lower rail top wall in the vertical direction; the rolling element contacts the lower rail bottom wall in the vertical direction, and can be used to provide rolling support for the upper rail component. Furthermore, the upper rail component can be displaced along the lower rail component through the rolling element. Compared with sliding, rolling has relatively less frictional resistance, which is beneficial to improving the smoothness of the upper rail component's displacement within the lower rail component. The second sliding element and the rolling element, in combination, can also eliminate the gap between the upper rail body and the lower rail component in the vertical direction.

[0008] Therefore, by configuring a gap-eliminating mechanism for the upper rail component, this utility model embodiment can effectively eliminate the gaps between the upper rail component and the lower rail component in the horizontal and vertical directions, reduce the possibility of relative swaying between the upper rail component and the lower rail component during relative displacement, thereby improving the running stability of the upper rail component, reducing abnormal noise during operation, reducing noise, and improving the user experience.

[0009] Optionally, the gap elimination mechanism further includes a support frame, on which both the lateral gap elimination component and the vertical gap elimination component are mounted.

[0010] Optionally, the number of gap-eliminating mechanisms is at least two, and each gap-eliminating mechanism is arranged at intervals along the longitudinal direction.

[0011] Optionally, the first sliding element has a first groove on at least one side that contacts the lower rail sidewall, and the first groove contains a lubricating medium; and / or, the second sliding element has a second groove on at least one side that contacts the lower rail top wall, and the second groove contains a lubricating medium.

[0012] Optionally, both the first sliding element and the second sliding element are wear-resistant blocks.

[0013] Optionally, it further includes an electric drive component, which includes a power generation unit, a drive shaft, and a reduction gearbox. The power generation unit and the reduction gearbox are both mounted on the upper rail component. The power generation unit is located on the outside of the upper rail component, and the reduction gearbox is located on the inside of the upper rail component. The drive shaft connects the power generation unit and the reduction gearbox.

[0014] Optionally, the upper rail body is snap-fitted with a protective sleeve, the drive shaft passes through the protective sleeve, and a gap is provided between the drive shaft and the protective sleeve.

[0015] Optionally, the power generation unit includes an integrated motor module and a control module.

[0035] like Figures 1-3 As shown, this utility model embodiment provides an electric slide rail assembly 1000, which can be applied in vehicles to achieve position adjustment of sliding entities such as vehicle seats and dashboards. The slide rail assembly 1000 includes an upper rail component 1100 and a lower rail component 1200.

[0036] The upper rail component 1100 may include an upper rail body 1110, which includes an adapter plate 1130. Specifically, the adapter plate 1130 may be located on the upper end of the upper rail body 1110. The adapter plate 1130, located on the upper side of the upper rail body 1110, can be used to connect with the sliding body, for example, by screws. The upper rail body 1110 and the adapter plate 1130 may be a single, integrally formed structure; alternatively, the upper rail body 1110 and the adapter plate 1130 may be manufactured separately and then connected by welding or other connection methods.

[0037] Both the upper rail component 1100 and the lower rail component 1200 can extend longitudinally, and the upper rail component 1100 is installed on the lower rail component 1200 and can be displaced along the lower rail component 1200 to drive the sliding body to slide longitudinally, thereby realizing the position adjustment of the sliding body.

[0038] Combination Figure 6The lower rail component 1200 may include a lower rail bottom wall 1210, two lower rail side walls 1220, two lower rail top walls 1230, and two lower rail flanges 1240. The lower rail bottom wall 1210 is used to connect to the vehicle floor, and the connection method may include, for example, screw connection. The two lower rail side walls 1220 may be arranged laterally opposite each other. The lower rail top walls 1230 and lower rail bottom walls 1210 may be arranged vertically opposite each other, with vertical also referring to the up-down direction. The two lower rail flanges 1240 may be arranged laterally opposite each of the two lower rail side walls 1220. The lower rail component 1200 may be a one-piece molded structure; alternatively, at least some of the wall panels in the lower rail component 1200 may be prepared separately and then assembled by welding or other connection methods.

[0039] As described in the background section, in related technologies, when the upper rail component moves within the lower rail component, the upper rail component is prone to wobbling relative to the lower rail component, resulting in relatively poor operational stability of the upper rail component. This may also lead to collisions between the upper and lower rail components, causing abnormal noise and significantly impacting the user experience.

[0040] To address this, in this embodiment of the invention, the upper rail component 1100 further includes a gap-eliminating mechanism 1120, which is mounted on the aforementioned upper rail body 1110. The gap-eliminating mechanism 1120 includes a horizontal gap-eliminating component 1121 and a vertical gap-eliminating component 1122.

[0041] The lateral gap-eliminating component 1121 includes a first sliding element 1121A, which contacts the lower rail sidewall 1220 in the lateral direction and can be used to eliminate the gap between the upper rail body 1110 and the lower rail component 1200 in the lateral direction.

[0042] The vertical gap-eliminating component 1122 includes a second sliding element 1122A and a rolling element 1122B. The second sliding element 1122A is used to contact the top wall 1230 of the lower rail vertically. The rolling element 1122B can be, for example, a bearing or a roller, and it contacts the bottom wall 1210 of the lower rail vertically, providing rolling support for the upper rail component 1100. Furthermore, the upper rail component 1100 can be displaced along the lower rail component 1200 via the rolling element 1122B. Compared to sliding, rolling has relatively less frictional resistance, which helps to improve the smoothness of the upper rail component 1100's displacement within the lower rail component 1200. The cooperation of the second sliding element 1122A and the rolling element 1122B can also eliminate the vertical gap between the upper rail body 1110 and the lower rail component 1200.

[0043] Therefore, by configuring the gap-eliminating mechanism 1120 on the upper rail component 1100, this utility model embodiment can effectively eliminate the gaps between the upper rail component 1100 and the lower rail component 1200 in the horizontal and vertical directions, reduce the possibility of relative swaying between the upper rail component 1100 and the lower rail component 1200 during relative displacement, thereby improving the running stability of the upper rail component 1100, reducing abnormal noise during operation, lowering noise levels, and improving the user experience.

[0044] More importantly, in this embodiment of the utility model, in addition to the rolling element 1122B being used to provide rolling support for the upper rail component 1100, the gap elimination mechanism 1120 uses the first sliding element 1121A and the second sliding element 1122A to eliminate gaps. The first sliding element 1121A and the second sliding element 1122A are not rolling elements, so their manufacturing costs can be relatively low, the product is relatively economical, and it is more conducive to its promotion and use in the electric slide rail assembly 1000, and has greater application prospects.

[0045] In some implementations, such as Figures 3-5 As shown, the gap elimination mechanism 1120 may also include a support frame 1123. The horizontal gap elimination component 1121 and the vertical gap elimination component 1122 may both be installed on the support frame 1123 so that they can be integrated and assembled through the support frame 1123, and the gap elimination mechanism 1120 and the upper rail body 1110 can be easily connected.

[0046] Here, this embodiment of the present invention does not limit the specific structural form of the support frame 1123 or the specific connection method between the support frame 1123 and the upper rail body 1110. In practical applications, those skilled in the art can make selections according to specific needs, as long as the requirements of use are met. For example, the specific structure of the support frame 1123 can be referred to Figures 3-5 The design is carried out. For example, the support frame 1123 can be connected to the upper rail body 1110 by welding.

[0047] The support frame 1123 may be provided with a snap-fit ​​feature, such as a slot or a pin, through which the first sliding element 1121A and the second sliding element 1122A can be installed and fixed. Alternatively, the first sliding element 1121A and the second sliding element 1122A may also be connected to the support frame 1123 by welding, bonding, or other connection methods, as long as the reliability and other relevant requirements for installation are met.

[0048] It is understood that the aforementioned support frame 1123 is not a necessary component. In some other implementations of this utility model, the aforementioned support frame 1123 may not exist. In this case, the aforementioned horizontal gap-eliminating component 1121 and vertical gap-eliminating component 1122 can be directly installed on the upper rail body 1110, which is also feasible.

[0049] In some implementations, such as Figure 3 As shown, there can be two gap-eliminating mechanisms 1120, which can be respectively disposed at both ends of the upper rail component 1100 in the longitudinal direction. The two gap-eliminating mechanisms 1120 can perform gap-eliminating treatment at different positions in the longitudinal direction of the upper rail component 1100, thereby improving the gap-eliminating effect. At the same time, the cooperation of the two gap-eliminating mechanisms 1120 can also improve the stability of the upper rail component 1100 when placed in the lower rail component 1200 and during operation.

[0050] It can be seen that, in addition to the above-mentioned implementation of setting the number of gap-eliminating mechanisms 1120 to two, in some other implementations of this utility model, the gap-eliminating mechanisms 1120 may also have other numbers, such as three or more.

[0051] In some implementations, such as Figure 4 and Figure 5 As shown, at least one side of the first sliding element 1121A that contacts the lower rail sidewall 1220 may be provided with a first groove 1121A1, and a lubricating medium is disposed in the first groove 1121A1. The lubricating medium may be, for example, lubricating grease or lubricating fluid, which can be used to reduce the friction between the first sliding element 1121A and the lower rail sidewall 1220, thereby improving the smoothness of sliding of the upper rail component 1100 within the lower rail component 1200.

[0052] Similarly, at least one side of the second sliding element 1122A that contacts the top wall 1230 of the lower rail can be provided with a second groove 1122A1, and a lubricating medium can also be provided in the second groove 1122A1. The lubricating medium can be used to reduce the friction between the second sliding element 1122A and the top wall 1230 of the upper rail, and can also improve the smoothness of sliding of the upper rail component 1100 in the lower rail component 1200.

[0053] Here, the embodiments of this utility model do not limit the specific shapes of the first groove 1121A1 and the second groove 1122A1. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements of use are met. For example, at least one of the first groove 1121A1 and the second groove 1122A1 can be set as a straight groove. As another example, at least one of the first groove 1121A1 and the second groove 1122A1 can be set as a cross-shaped groove.

[0054] In some implementations, both the first sliding element 1121A and the second sliding element 1122A can be wear-resistant blocks. These wear-resistant blocks can be elastic blocks, such as plastic blocks or rubber blocks. Alternatively, they can be rigid blocks, such as metal friction plates. It is understood that compared to rolling components such as bearings and rollers, sliding components such as plastic blocks, rubber blocks, and metal friction plates have relatively lower costs, which helps improve the product's economic efficiency.

[0055] With this configuration, both the first sliding element 1121A and the second sliding element 1122A can deform to a certain extent under compressive force, thereby achieving better close contact between the upper rail component 1100 and the lower rail component 1200 in both the lateral and vertical directions, which helps to eliminate gaps. Furthermore, the lower rail component 1200 is typically made of metal, and the hardness of the first sliding element 1121A and the second sliding element 1122A (which are in the form of wear-resistant blocks) is lower than that of the lower rail component 1200, reducing wear on the lower rail component 1200 and extending its service life.

[0056] Here, the specific shapes of the first sliding element 1121A and the second sliding element 1122A are not limited in this embodiment. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements of use are met. For example, see [link to relevant documentation]. Figure 5 The first sliding element 1121A can be annular. For example, see [reference needed]. Figure 4 The first sliding element 1121A can also be a combination of a rectangle and an arc shape.

[0057] In some implementations, the electric drive component 1300 may include a power generation unit 1310, a drive shaft 1320, a reduction gearbox 1330, and a lead screw component 1340.

[0058] Both the power generation unit 1310 and the reduction gearbox 1330 can be mounted on the upper rail component 1100; wherein, the power generation unit 1310 can be located on the outside of the upper rail component 1100, and the reduction gearbox 1330 can be located on the inside of the upper rail component 1100. The drive shaft 1320 can pass through the upper rail component 1100 and can connect the output shaft of the power generation unit 1310 and the input part of the reduction gearbox 1330 to realize the transmission connection between the power generation unit 1310 and the reduction gearbox 1330.

[0059] The drive shaft 1320 can be a rigid shaft. Alternatively, the drive shaft 1320 can also be a flexible shaft.

[0060] like Figure 7 and Figure 8 As shown, the upper rail component 1100 may also be equipped with a protective sleeve 1140, through which the drive shaft 1320 can pass. The protective sleeve 1140 provides protection for the drive shaft 1320, reducing impact damage to the drive shaft 1320 from other components. Furthermore, the drive shaft 1320 and the protective sleeve 1140 may not be in contact; that is, a gap may be provided between the drive shaft 1320 and the protective sleeve 1140. This further reduces the impact of the protective sleeve 1140 on the normal rotation of the drive shaft 1320.

[0061] Specifically, the aforementioned protective sleeve 1140 can be snap-fitted onto the upper rail body 1110, for example, it can be a connector plate 1130 snap-fitted onto the upper rail body 1110.

[0062] Combination Figure 9 The power generation unit 1310 may include an integrated motor module 1311 and a control module 1312, so that the power generation unit 1310 itself can integrate the control module 1312, and correspondingly, there is no need to set up an additional controller, which saves installation space. The control module 1312 may be provided with a connection interface 1312A, which is used for communication connection with other devices.

[0063] The lead screw component 1340 may be located within the lower rail component 1200. Specifically, lead screw supports 1350 may be provided at both ends of the axial direction of the lead screw component 1340. The lead screw supports 1350 may be connected to the bottom wall 1210 of the lower rail by screws or the like, thus enabling the lead screw component 1340 to be installed and fixed within the lower rail component 1200.

[0064] The reducer 1330 can be inserted into the lead screw assembly 1340, and the output of the reducer 1330 can be connected to the lead screw assembly 1340 for transmission. In this way, when the motor module 1311 starts, the driving force of the motor module 1311 can be transmitted to the reducer 1330 through the transmission shaft 1320, so that the reducer 1330 can be displaced along the lead screw assembly 1340, thereby driving the upper rail assembly 1100 to move relative to the lower rail assembly 1200.

[0065] This utility model embodiment also provides an electric slide rail assembly, including at least two electric slide rail components 1000. These electric slide rail components 1000 are the same as those described in the aforementioned implementations, and the electric slide rail components 1000 can be arranged at intervals along the lateral direction. It is understood that the electric slide rail assembly may also include only one electric slide rail component 1000, which is also feasible, depending on the specific usage requirements of the sliding body.

[0066] This utility model embodiment also provides a vehicle, including a sliding body and an electric slide rail assembly. The sliding body can be, for example, a vehicle seat, a sub-dashboard, or other in-vehicle component. The sliding body is mounted on the electric slide rail assembly so that its position can be adjusted within the vehicle via the electric slide rail assembly, which is specifically the aforementioned electric slide rail assembly.

[0067] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
