Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a slide rail assembly and a vehicle. Specifically, the slide rail assembly can be applied to an electric slide rail scenario or a manual slide rail scenario. Background Art

[0002] The slide rail assembly includes an upper rail component and a lower rail component. The upper rail component is used to connect to the seat body, and the lower rail component is used to connect to the vehicle floor so as to mount the seat body on the vehicle floor. At the same time, the upper rail component can slide relative to the lower rail component, which can be used to adjust the installation position of the seat body inside the vehicle. With the development of the times and the progress of society, the seat body is equipped with more and more functions. Correspondingly, the weight of the seat body is getting heavier and heavier, which requires the slide rail assembly to have better supporting performance.

[0003] Therefore, how to provide a solution to overcome or alleviate the above defects is still a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0004] The object of the present invention is to provide a slide rail assembly and a vehicle, wherein the slide rail assembly can have relatively better supporting performance.

[0005] To solve the above technical problems, the present invention provides a slide rail assembly. The extending direction of the slide rail assembly is the first direction. The slide rail assembly includes an upper rail component, a lower rail component, and a rolling support component. The upper rail component includes an upper rail top plate, two upper rail side plates, and two upper rail outward flanges. The lower rail component includes a lower rail bottom plate and two lower rail side parts. The two upper rail outward flanges are respectively inserted into the two lower rail side parts. The rolling support component is arranged between the upper rail outward flange and the lower rail side part. The rolling support component includes a support base body. At least two balls spaced along the first direction are rollingly arranged at the upper end part of the support base body, and at least two rollers spaced along the first direction are rollingly arranged at the lower end part of the support base body. The balls and the rollers are both abutted against the upper rail outward flange and the lower rail side part. The lower rail side part and the upper rail outward flange are both tangent to the outer wall surface of the roller through a plane. The lower rail side part is tangent to the outer wall surface of the ball through a plane. The upper rail outward flange is tangent to the outer wall surface of the ball through an arc surface.

[0006] In the above solution, a rolling support component is configured inside the slide rail assembly. The rolling support component includes balls, rollers, and a support base. The roller is in a cylindrical structure and is arranged at the lower end of the support base. The side of the lower rail and the outward flanging of the upper rail are tangent to the outer wall surface of the roller through planes, so that the roller can support and contact the side of the lower rail and the outward flanging of the upper rail in a line contact manner, which is beneficial to reliably support the upper rail component, thereby improving the support performance of the slide rail assembly. The side of the lower rail can be tangent to the outer wall surface of the ball through a plane to improve the smoothness of the ball rolling, while the outward flanging of the upper rail can be tangent to the outer wall surface of the ball through an arc surface to better install and limit the ball, improve the installation reliability of the ball, and better play the clearance elimination function of the ball.

[0007] Optionally, in the same rolling support component, the balls and the rollers are arranged in a staggered manner along the first direction.

[0008] Optionally, in the same rolling support component, the distance between two adjacent balls along the first direction is less than the distance between two adjacent rollers along the first direction.

[0009] Optionally, the number of the rolling support components between the outward flanging of the upper rail and the side of the lower rail on the same side is at least two, and the rolling support components are arranged at intervals along the first direction.

[0010] Optionally, the outward flanging of the upper rail includes a flanging main body and two flanging stoppers. The two flanging stoppers are respectively located on both sides of the flanging main body along the first direction; the rolling support component is located between the two flanging stoppers, and both flanging stoppers can stop the rolling support component along the first direction.

[0011] Optionally, the side of the lower rail includes a lower rail side plate, a lower rail top plate, and an inward flanging of the lower rail. The lower rail top plate and the lower rail side plate are arranged at an angle, and the inward flanging of the lower rail and the lower rail top plate are arranged at an angle. The extending direction of the end of the flanging main body can point to the lower rail top plate, or the extending direction of the end of the flanging main body can point to the connection between the lower rail top plate and the inward flanging of the lower rail.

[0012] Optionally, both the flanging main body and the lower rail side plate are in a bent plate structure.

[0013] Optionally, the lower rail side plate includes a first lower rail plate body, a second lower rail plate body, and a third lower rail plate body connected to each other. The first lower rail plate body is connected to the lower rail bottom plate, and the third lower rail plate body is connected to the lower rail top plate.

[0014] Optionally, the flanging body includes a first upper rail plate body, a second upper rail plate body, and a third upper rail plate body that are sequentially connected, and the first upper rail plate body is connected to the upper rail side plate.

[0015] The present invention also provides a vehicle, including a vehicle body, a seat body, and a slide rail assembly. The slide rail assembly is the above-mentioned slide rail assembly. The upper rail component is connected to the seat body, and the lower rail component is connected to the vehicle body.

[0016] Since the aforementioned slide rail assembly already has the above technical effects, therefore, the vehicle having this slide rail assembly should also have similar technical effects, so it will not be elaborated here. Brief Description of the Drawings

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the description of the embodiments of the present invention, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include one or more of such features.

[0033] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, "connected" can be a detachable connection or a non - detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0034] The orientation terms mentioned in the embodiments of the present invention, such as "inside", "outside", etc., are only with reference to the direction of the accompanying drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present invention, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the embodiments of the present invention.

[0035] In the description of the embodiments of the present invention, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0036] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the slide rail assembly.

[0037] As Figure 1 shown, an embodiment of the present invention provides a slide rail assembly, which includes a slide rail component 1000. The slide rail component 1000 includes an upper rail part 1100 and a lower rail part 1200. The upper rail part 1100 can be inserted into the lower rail part 1200 and can slide along the lower rail part 1200.

[0038] In the embodiments of the present invention, a first direction X, a second direction Y and a third direction Z can be defined. The first direction X can specifically be the extending direction of the slide rail component 1000; in some implementation manners, the first direction X is also referred to as the length direction of the slide rail component 1000. In the installation surface of the slide rail component 1000, the direction that forms an angle with the first direction X is the second direction Y, and this angle can be, for example, 90 degrees, etc.; in some implementation manners, the second direction Y is also referred to as the width direction of the slide rail component 1000. The direction perpendicular to the installation surface of the slide rail component 1000 is the third direction Z; in some implementation manners, the third direction Z is also referred to as the up-down direction, or the height direction of the slide rail component 1000, etc.

[0039] In practical applications, the slide rail components 1000 usually exist in pairs, that is, the slide rail assembly can include two slide rail components 1000, and the two slide rail components 1000 can be arranged at intervals along the second direction Y. This implementation manner can be referred to Figure 1 . It should be noted that the embodiments of the present invention do not exclude the case where the slide rail component 1000 is used alone, or three, four, or even more are provided and used together.

[0040] Taking the slide rail assembly including two slide rail components 1000 as an example, in combination with Figure 1, when the slide rail assembly is an electric slide rail assembly, it may further include a driving component 2000. The driving component 2000 may specifically include a driving bracket 2100, a driving motor 2200, and a gearbox 2300. The driving motor 2200 may be installed on the driving bracket 2100 and may be connected to the gearbox 2300 through a flexible shaft or the like. The gearbox 2300 may be at least partially inserted into the upper rail component 1100 and may be connected to a lead screw component installed on the lower rail component 1200, so as to drive the upper rail component 1100 to displace relative to the lower rail component 1200 along the first direction X under the drive of the driving motor 2200.

[0041] In addition, the above slide rail assembly may also be a manual slide rail assembly. In this case, the Figure 1 shown driving component 2000 can be omitted and replaced with a manual unlocking lever to realize the movement unlocking between the upper rail component 1100 and the lower rail component 1200.

[0042] That is to say, the slide rail assembly 1000 provided in the embodiments of the present invention can be applied to either an electric slide rail assembly or a manual slide rail assembly.

[0043] As described in the background art section, as the functions configured on the seat body are increasing, correspondingly, the weight of the seat body is getting heavier, which requires the slide rail assembly to have better supporting performance. In view of this, the embodiments of the present invention can improve the supporting performance of the slide rail assembly by adjusting the structural form of the slide rail assembly to adapt to the support of a seat body with a relatively large mass.

[0044] Please refer to Figures 2 - 6 , Figure 2 which is a schematic structural diagram of an implementation manner of the slide rail assembly provided by the present invention; Figure 3 is a split structure diagram of the slide rail assembly; Figure 4 is Figure 3 a partial structure diagram of Figure 5 is Figure 3 a front view of Figure 6 is Figure 5 a partial structure diagram of

[0045] As Figures 2 - 4 shown, the upper rail component 1100 includes an upper rail top plate 1110, two upper rail side plates 1120, and two upper rail flanges 1130. The lower rail component 1200 includes a lower rail bottom plate 1210 and two lower rail sides 1220. The two upper rail flanges 1130 can be respectively inserted into the two lower rail sides 1220 along the first direction X.

[0046] In an embodiment of the present invention, the slide rail assembly 1000 further includes a rolling support member 1300. The rolling support member 1300 is disposed between the upper rail outer flange 1130 and the lower rail side portion 1220 and is used to guide and support the relative sliding of the upper rail member 1100 and the lower rail member 1200.

[0047] The rolling support member 1300 includes a support base 1330. At least two balls 1310 spaced along a first direction are rotatably disposed at the upper end portion of the support base 1330, and at least two rollers 1320 spaced along the first direction are rotatably disposed at the lower end portion of the support base 1330. The support base 1330 can integrally assemble the balls 1310 and the rollers 1320 to facilitate the installation of the rolling support member 1300 between the upper rail member 1100 and the lower rail member 1200.

[0048] It can be known that mounting holes can be provided at both the upper end portion and the lower end portion of the rolling support member 1300. The balls 1310 and the rollers 1320 can be disposed in the mounting holes. The orifice of the mounting hole can be appropriately smaller than the balls 1310 and the rollers 1320, so that the balls 1310 and the rollers 1320 need to be pressed into the mounting holes by means of a certain pressure, but are restricted by the orifice, so that the balls 1310 and the rollers 1320 will not fall out of the support base 1330. At the same time, the balls 1310 and the rollers 1320 can freely roll relative to the support base 1330 in the mounting holes.

[0049] Both the balls 1310 and the rollers 1320 are in contact with the upper rail outer flange 1130 and the lower rail side portion 1220. That is, an interference fit assembly relationship is adopted between the balls 1310 and the rollers 1320 and the upper rail outer flange 1130 and the lower rail side portion 1220, so that relatively close contact can be ensured between the balls 1310 and the rollers 1320 and the upper rail outer flange 1130 and the lower rail side portion 1220. Among them, both the lower rail side portion 1220 and the upper rail outer flange 1130 are tangent to the outer wall surface of the roller 1320 through a plane, the lower rail side portion 1220 is tangent to the outer wall surface of the ball 1310 through a plane, and the upper rail outer flange 1130 is tangent to the outer wall surface of the ball 1310 through an arc surface.

[0050] In the above solution, a rolling support member 1300 is arranged in the slide rail assembly 1000. The rolling support member 1300 includes balls 1310, rollers 1320 and a support base 1330. The roller 1320 is in a columnar structure and is arranged at the lower end of the support base 1330. Both the lower rail side 1220 and the upper rail flanging 1130 are tangent to the outer wall surface of the roller 1320 through planes, so that the roller 1320 and the lower rail side 1220 as well as the upper rail flanging 1130 can be in supporting contact in a line contact manner, which is beneficial to reliably support the upper rail member 1100, thereby improving the support performance of the slide rail assembly 1000. The lower rail side 1220 can be tangent to the outer wall surface of the ball 1310 through a plane to improve the smoothness of the rolling of the ball 1310, while the upper rail flanging 1130 can be tangent to the outer wall surface of the ball 1310 through an arc surface, so as to better limit the installation of the ball 1310, improve the installation reliability of the ball 1310, and better play the clearance elimination function of the ball 1310 in the second direction Y and the third direction Z.

[0051] It can be seen that among the balls 1310 and the rollers 1320, the balls 1310 mainly play the function of eliminating clearance and synchronously realize the supporting function, while the rollers 1320 mainly play the supporting function to ensure the uniqueness of the relative postures of the upper rail member 1100 and the lower rail member 1200.

[0052] In the same rolling support member 1300, the numbers of the balls 1310 and the rollers 1320 are not limited herein and can be specifically adjusted according to needs. For example, in combination with Figure 3 and Figure 4 , the same rolling support member 1300 can be configured with 3 balls 1310 and 3 rollers 1320.

[0053] In some optional implementation manners, as shown in Figure 3 and Figure 4 , the upper rail flanging 1130 may include a flanging main body 1311 and two flanging stoppers 1132.

[0054] The two flanging stoppers 1132 may be respectively located on both sides of the flanging main body 1311 along the first direction X. The rolling support member 1300 may be located between the two flanging stoppers 1132, and both flanging stoppers 1132 can stop the rolling support member 1300 along the first direction X to reduce the possibility of the rolling support member 1300 slipping off the upper rail member 1100.

[0055] In some optional implementation manners, as shown in Figure 5 and Figure 6As shown, in the same rolling support member 1300, the balls 1310 and the rollers 1320 can be arranged with a dislocation along the first direction X. That is, the cross-section perpendicular to the first direction X and passing through the center of the ball 1310, and the cross-section perpendicular to the first direction X and passing through the central axis of the roller 1320 are arranged with a dislocation along the first direction X, and there is a distance D between these two cross-sections along the first direction X.

[0056] In this way, without increasing the number of the balls 1310 and the rollers 1320, the rolling support member 1300 can provide more support points arranged at intervals along the first direction X, and can better play the supporting role of the rolling support member 1300 in the slide rail assembly 1000, thereby improving the supporting performance of the slide rail assembly 1000. At the same time, arranging the balls 1310 and the rollers 1320 with a dislocation along the first direction X can also reduce the interference fit amount between the rolling support member 1300 and the upper rail member 1100 and the lower rail member 1200 during assembly, making the assembly process relatively easy.

[0057] It should be understood that in some other implementation manners of the embodiments of the present invention, the above-mentioned balls 1310 and rollers 1320 may not be arranged with a dislocation along the first direction X, and this is also feasible.

[0058] In some optional implementation manners, as Figure 5 and Figure 6 shown, in the same rolling support member 1300, the distance L1 between two adjacent balls 1310 along the first direction X can be less than the distance L2 between two adjacent rollers 1320 along the first direction X. In this way, the supporting length of the rolling support member 1300 can be effectively increased, and the supporting role of the rolling support member 1300 can be better played, thereby improving the supporting performance of the slide rail assembly 1000.

[0059] It should be understood that in some other implementation manners of the embodiments of the present invention, there may also be other relationships between the distance L1 between two adjacent balls 1310 along the first direction X and the distance L2 between two adjacent rollers 1320 along the first direction X, which are not limited herein.

[0060] Here, the embodiments of the present invention do not limit the number of the rolling support members 1300 between the upper rail flanging 1130 and the lower rail side portion 1220 located on the same side along the second direction Y. In the Figure 3 and Figure 5 implementation manners, the number of the rolling support members 1300 is two. In some other implementation manners of the embodiments of the present invention, the number of the rolling support members 1300 can also be three, four or more, and the rolling support members 1300 can be arranged at intervals along the first direction X.

[0061] An important function of the slide rail assembly is to protect the safety of the occupants of the vehicle, and one of the important parameters is the diagonal tensile strength. The diagonal tensile strength specifically refers to the strength at which the slide rail assembly fails when subjected to a collision load, and is a key indicator for measuring the performance of the slide rail assembly when a vehicle crashes. In the existing related technologies, the diagonal tensile strength of the slide rail assembly is generally only about 20KN, which is often difficult to meet the requirements when used in the middle row of seats or the back row of seats.

[0062] In view of this, a common solution in the prior art is to add a clamp structure to improve the strength of the slide rail assembly. However, the addition of the clamp structure will result in a relatively large number of parts in the slide rail assembly, a relatively complex structure, and a relatively high weight, which is not conducive to the current market's requirements for lightweight vehicles.

[0063] Based on the above technical status, the applicant has adjusted the structural form of at least the upper rail component 1100 in the slide rail assembly after extensive research, which can significantly increase the anti-slant tensile strength of the slide rail assembly 1000 without adding components, thereby improving the safety performance of the slide rail assembly 1000. In addition, the complexity of the structure of the slide rail assembly 1000 can be avoided, the mass of the slide rail assembly 1000 can be reduced, and it is conducive to realizing the lightweight design of the vehicle.

[0064] Specifically, please refer to Figures 7 - 11 , Figure 7 It is a structural diagram of the connection between the upper rail component and the lower rail component at the flange body; Figure 8 for Figure 7 A simplified diagram of the force analysis of the middle slide rail assembly when peeling occurs under force; Figure 9 A simplified diagram of force analysis of a slide rail assembly in the prior art when peeling occurs under force; Figure 10 This is a simulation experiment diagram of the anti-slant tensile strength of the slide rail assembly provided by the present invention; Figure 11 for Figure 10 Curve diagram of the change in the diagonal tensile strength during the simulation experiment.

[0065] like Figure 7 As shown, in the embodiment of the present invention, the lower rail side portion 1220 may include a lower rail side plate 1221, a lower rail top plate 1222 and a lower rail inner flange 1223. The lower rail top plate 1222 and the lower rail side plate 1221 are arranged at an angle, that is, there may be a bend between the lower rail top plate 1222 and the lower rail side plate 1221. The lower rail inner flange 1223 and the lower rail top plate 1222 are arranged at an angle, that is, there may also be a bend between the lower rail inner flange 1223 and the lower rail top plate 1222.

[0066] In the upper rail outer flange 1130, the extension direction of the end of the flange body 1131 is ( Figure 7The direction of the hollow arrow (i.e., the direction of the hollow arrow) can point to the lower rail top plate 1222, or the extending direction of the end of the flanging body 1131 can point to the connection between the lower rail top plate 1222 and the lower rail inner flanging 1223. It should be understood that the end of the flanging body 1131 specifically refers to the end of the flanging body 1131 that is away from its connection with the upper rail side plate 1120; this end can be a flat plate structure, in which case the extending direction of the end is also the extending direction of this flat plate structure, or this end can also be a curved panel structure, in which case the extending direction of the end is also the tangential direction of this curved panel structure.

[0067] Combined with Figure 8 , for the slide rail assembly 1000 provided by the embodiment of the present invention, when a vehicle collides and causes the upper rail component 1100 and the lower rail component 1200 to separate, the end of the flanging body 1131 can directly act on the lower rail top plate 1222 or the connection between the lower rail top plate 1222 and the lower rail inner flanging 1223. At this time, if the upper rail component 1100 and the lower rail component 1200 are to separate, the upper rail component 1100 needs to drive the lower rail top plate 1222 to flip relative to the lower rail side plate 1221, and needs to drive the lower rail inner flanging 1223 to flip relative to the lower rail top plate 1222, that is, it needs to overcome two bends in the lower rail component 1200. The entire flanging body 1131 is subjected to a first deformation force F1 downward along the third direction Z by the lower rail component 1200, and the size of the moment of the first deformation force F1 is L1.

[0068] Combined with Figure 9 , analyze the slide rail assembly in the prior art together. As Figure 9 shown, for the slide rail assembly in the prior art, the extending direction of the end of the upper rail outer flanging 1130' points to the lower rail inner flanging 1223'. When a vehicle collides and causes the upper rail component 1100' and the lower rail component 1200' to separate, the end of the upper rail outer flanging 1130' can directly act on the lower rail inner flanging 1223'. At this time, if the upper rail component 1100' and the lower rail component 1200' are to separate, the upper rail component 1100' needs to drive the lower rail inner flanging 1223' to flip relative to the lower rail top plate 1222', that is, it needs to overcome one bend in the lower rail component 1200'. The upper rail outer flanging 1130' is then subjected to a second deformation force F2 along the second direction Y by the lower rail component 1200', and the size of the moment of the second deformation force F2 is L2, and L2 is significantly greater than L1.

[0069] Through comparative analysis, it can be seen that in the embodiment of the present invention, by adjusting the structural shape of the upper rail component 1100, when a collision occurs, the number of bends of the lower rail component 1200 that the upper rail component 1100 and the lower rail component 1200 need to overcome to separate is more, the difficulty of deformation of the lower rail component 1200 is relatively high, and the dimension L1 of the moment of the first deformation force F1 received by the flanging main body 1131 is relatively small, making the difficulty of deformation of the upper rail outer flanging 1130 relatively high. Thus, in the embodiment of the present invention, the difficulty of separation between the upper rail component 1100 and the lower rail component 1200 is relatively high as a whole, so that the anti-oblique pulling strength of the slide rail assembly 1000 can be improved.

[0070] In some alternative implementation manners, such as Figure 7 as shown, both the flanging main body 1131 and the lower rail side plate 1221 can be bending plate structures to further improve the structural strength of the upper rail component 1100 and the lower rail component 1200.

[0071] The lower rail side plate 1221 can include a first lower rail plate body 1221A, a second lower rail plate body 1221B, and a third lower rail plate body 1221C connected to each other. The first lower rail plate body 1221A is connected to the lower rail bottom plate 1210. The second lower rail plate body 1221B and the first lower rail plate body 1221A can be arranged at an angle, that is, there can be a bend between the second lower rail plate body 1221B and the first lower rail plate body 1221A. The third lower rail plate body 1221C and the second lower rail plate body 1221B can be arranged at an angle, that is, there can be a bend between the third lower rail plate body 1221C and the second lower rail plate body 1221B. The third lower rail plate body 1221C can be connected to the lower rail top plate 1222.

[0072] The above-mentioned first lower rail plate body 1221A can be a flat plate structure and can be arranged at an angle with the second direction Y to provide an oblique support for the roller 1320. The second lower rail plate body 1221B can be a flat plate structure or a curved plate structure. The third lower rail plate body 1221C can be a flat plate structure so that the plane is tangent to the outer wall surface of the ball 1310.

[0073] The flanging main body 1131 can include a first upper rail plate body 1131A, a second upper rail plate body 1131B, and a third upper rail plate body 1131C. The first upper rail plate body 1131A is connected to the upper rail side plate 1120, and the second upper rail plate body 1131B connects the first upper rail plate body 1131A and the third upper rail plate body 1131C. Among the first upper rail plate body 1131A, the second upper rail plate body 1131B, and the third upper rail plate body 1131C, they can also be arranged at an angle with each other, that is, there can be a bend between each two of them.

[0074] The above-mentioned first upper rail plate body 1131A can be a flat plate structure and can be arranged at an angle to the second direction Y to obliquely support the roller 1320. The second upper rail plate body 1131B can be a flat plate structure or a curved plate structure. The third upper rail plate body 1131C can be a curved plate structure so as to be tangent to the outer wall surface of the ball 1310 through an arc surface.

[0075] It should be understood that the above description of the specific structural forms of the upper rail outer flanging 1130 and the lower rail side plate 1221 is only an exemplary illustration made in combination with Figure 7 the embodiments of the present invention, and it cannot be used as a limitation on the implementation scope of the slide rail assembly 1000 provided by the embodiments of the present invention. Under the condition of meeting the function, the above-mentioned upper rail outer flanging 1130 and the lower rail side plate 1221 can also adopt other structural forms. For example, at least one of the upper rail outer flanging 1130 and the lower rail side plate 1221 can only include two plate bodies, or at least one of the upper rail outer flanging 1130 and the lower rail side plate 1221 can include at least four plate bodies.

[0076] For the slide rail assembly 1000 provided by the embodiments of the present invention, the applicant also carried out a simulation test on its anti-oblique tension strength. Combining Figure 10 and Figure 11 , the slide rail assembly 1000 in the embodiments of the present invention can have an anti-oblique tension strength of up to 50 KN, far exceeding 20 KN in the prior art. When used inside a vehicle, it can better protect the vehicle occupants to improve safety performance.

[0077] In some alternative implementation manners, the top surface of the upper rail top plate 1110 can be a plane. In this way, the structural form of the upper rail top plate 1110 can be more concise. On the one hand, it can simplify the structure of the upper rail component 1100 to reduce costs, and on the other hand, it is also more conducive to connecting the upper rail top plate 1110 to the seat body through different installation methods.

[0078] For example, as shown in Figure 1 mentioned above, the top surface of the upper rail top plate 1110 can be provided with a connecting column 1140, and the connecting column 1140 can specifically be a riveting column or the like.

[0079] The embodiments of the present invention also provide a vehicle, including a vehicle body, a seat body, and a slide rail assembly 1000. The slide rail assembly 1000 can be the slide rail assembly 1000 involved in any of the foregoing implementation manners. In the slide rail assembly 1000, the upper rail component 1100 is connected to the seat body, and the lower rail component 1200 is connected to the vehicle body.

[0080] Since the foregoing slide rail assembly 1000 already has the above technical effects, therefore, a vehicle having the slide rail assembly 1000 should also have similar technical effects, so it will not be elaborated here.

[0081] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
