AI Technical Summary
The existing sliding rail assembly has insufficient anti-diagonal tensile strength, making it difficult to effectively protect the safety of people inside the vehicle. In particular, the sliding rail assembly is prone to detachment during vehicle collisions, failing to provide reliable safety protection.
By adjusting the structural shape of the upper rail component, the end of the outer flange of the upper rail is made to point towards the top plate of the lower rail or the connection between the top plate of the lower rail and the inner flange of the lower rail. This increases the number of bends and deformation torque that need to be overcome when the upper and lower rails are separated, thereby improving the anti-diagonal tensile strength of the slide rail assembly.
The anti-diagonal tensile strength of the slide rail assembly is significantly improved, enhancing safety performance and making it more difficult to separate during a vehicle collision, thus providing higher safety protection. The anti-diagonal tensile strength reaches 50KN, far exceeding the 20KN of the existing technology.

Description
TECHNICAL FIELD
[0001] The utility model relates to vehicle technical field, concretely relates to a slide rail assembly and vehicle, and the slide rail assembly specifically can be applied to electric slide rail or manual slide rail scene. BACKGROUND
[0002] The slide rail assembly comprises an upper rail component and a lower rail component, the upper rail component is connected with the seat body, and the lower rail component is connected with the vehicle floor to mount the seat body on the vehicle floor.
[0003] Another important function of the slide rail assembly is to protect the safety of the vehicle occupants, including the driver and the passenger. When the vehicle collides forward, the vehicle occupants and the seat body will produce a forward impact force together. Because the upper rail component is connected with the seat body, the impact force will be transmitted to the upper rail component and act on the connection between the upper rail component and the lower rail component. The slide rail assembly can only resist the impact force to prevent the upper rail component from being separated from the lower rail component during the collision, thereby effectively protecting the safety of the vehicle occupants. However, the existing related technology does not have a reasonable design, resulting in an anti-tension strength of the slide rail assembly of only 20KN, which cannot reliably guarantee the safety of the vehicle occupants.
[0004] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem to be solved by those skilled in the art. UTILITY MODEL CONTENT
[0005] The utility model aims to provide a slide rail assembly and a vehicle, wherein the anti-tension strength of the slide rail assembly can be relatively high, and the safety performance can be relatively good.
[0006] To solve the above technical problems, the utility model provides a slide rail assembly, which comprises an upper rail component and a lower rail component, the upper rail component comprises an upper rail top plate, two upper rail side plates and two upper rail outer flanges, the lower rail component comprises a lower rail bottom plate and two lower rail side parts, the lower rail side part comprises a lower rail side plate, a lower rail top plate and a lower rail inner flange, the lower rail top plate and the lower rail side plate are arranged at an angle, the lower rail inner flange and the lower rail top plate are arranged at an angle, and the two upper rail outer flanges are respectively inserted into the two lower rail side parts.

In this way, when the vehicle collides and the upper rail component and the lower rail component are separated, the at least partially terminal end of the upper rail outer flange can directly act on the lower rail top plate or the joint of the lower rail top plate and the lower rail inner flange. At this time, if the upper rail component and the lower rail component are to be separated, the upper rail component needs to drive the lower rail top plate to overturn relative to the lower rail side plate and needs to drive the lower rail inner flange to overturn relative to the lower rail top plate, that is, the two bending positions in the lower rail component need to be overcome, and the difficulty of deformation of the lower rail component is relatively high.
[0008] In addition, when the upper rail component and the lower rail component are to be separated, the entire upper rail outer flange is subjected to the first deformation force of the lower rail component in the vertical direction downward, and the moment of the first deformation force is relatively short, so that the difficulty of deformation of the upper rail outer flange is also relatively high.
[0009] Therefore, the difficulty of separation of the upper rail component and the lower rail component in the embodiment of the utility model is relatively high as a whole, so that the anti-inclined tensile strength of the slide rail assembly can be improved, and the safety performance of the slide rail assembly can be improved.
[0010] Optionally, the upper rail outer flange and the lower rail side plate are both bending plate structures.

[0013] Optionally, the rolling support component comprises a first rolling ball and a second rolling ball, the first rolling ball is located on the upper side of the second rolling ball, and the first rolling ball and the second rolling ball are both arranged to roll between the upper rail outer flange and the lower rail side plate.

[0015] Optionally, one of the upper rail outer flange and the lower rail side plate is tangent to a plane and an outer wall surface of the first rolling ball; and / or, one of the upper rail outer flange and the lower rail side plate is tangent to a plane and an outer wall surface of the second rolling ball.
[0016] Optionally, the rolling support component further comprises a support base body, and the first rolling ball and the second rolling ball are both rolling arranged on the support base body.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.
[0039] Please refer to Figure 1 , Figure 1 The structure diagram of the slide rail assembly.
[0040] As Figure 1 shown, the utility model embodiment provides a slide rail assembly, including slide rail assembly 1000. Slide rail assembly 1000 includes upper rail part 1100 and lower rail part 1200, and upper rail part 1100 can be inserted into lower rail part 1200 and can slide along lower rail part 1200.
[0041] In the embodiments of the utility model, the first direction X, the second direction Y and the third direction Z can be defined. The first direction X can be the extension direction of the slide rail assembly 1000, and in some implementations, the first direction X is also called the length direction of the slide rail assembly 1000. In the mounting surface of the slide rail assembly 1000, the direction arranged at an angle with the first direction X is the second direction Y, which can be 90 degrees, for example. In some implementations, the second direction Y is also called the width direction of the slide rail assembly 1000. The direction perpendicular to the mounting surface of the slide rail assembly 1000 is the third direction Z, and in some implementations, the third direction Z is also called the up-down direction or the height direction of the slide rail assembly 1000.
[0042] In actual application, the slide rail assembly 1000 usually exists in pairs, that is, the slide rail assembly can include two slide rail assemblies 1000, and the two slide rail assemblies 1000 can be arranged at intervals along the second direction Y. This implementation can be referred to as Figure 1 It should be noted that the embodiments of the utility model do not exclude the use of the slide rail assembly 1000 alone or the use of three, four or more.
[0043] Taking the slide rail assembly including two slide rail components 1000 as an example, combining Figure 1 When the slide rail assembly is an electric slide rail assembly, it can further include a driving assembly 2000. The driving assembly 2000 can specifically include a driving bracket 2100, a driving motor 2200 and a gear box 2300. The driving motor 2200 can be mounted on the driving bracket 2100 and can be connected to the gear box 2300 through a flexible shaft or the like. The gear box 2300 can be at least partially inserted into the upper rail component 1100 and can be connected to a lead screw component mounted on the lower rail component 1200, so that under the driving of the driving motor 2200, the upper rail component 1100 is driven to move relative to the lower rail component 1200 along the first direction X.
[0044] In addition to the above, the slide rail assembly can also be a manual slide rail assembly. At this time, the driving assembly 2000 shown in Figure 1 can be omitted, and a manual unlocking rod can be replaced to realize the movement unlocking between the upper rail component 1100 and the lower rail component 1200.
[0045] That is, the slide rail component 1000 provided in the embodiments of the present application can be applied to an electric slide rail assembly or a manual slide rail assembly.
[0046] As described in the background section, an important function of the slide rail component is to protect the safety of the people in the vehicle, and an important parameter index is the anti-inclined strength. The anti-inclined strength specifically refers to the strength at which the slide rail component fails under impact loading, and is a key index for measuring the performance of the slide rail component in the event of a vehicle collision. In the existing related technology, the anti-inclined strength of the slide rail component is generally only about 20KN, and when used in a middle-row seat or a rear-row seat, it is often difficult to meet the requirements of use.
[0047] In view of this, a common solution in the prior art is to increase the hoop structure to improve the strength of the slide rail component. However, the increase of the hoop structure will result in a relatively large number of parts in the slide rail component, a relatively complex structure and a relatively high weight, which is not conducive to the lightweight requirement of the vehicle on the current market.
[0048] Based on the above technical status, the applicant has made a lot of research, and adjusted the structure of at least the upper rail component 1100 of the slide rail component. Without increasing the parts, the anti-inclined strength of the slide rail component 1000 can be greatly increased, thereby improving the safety performance of the slide rail component 1000. Moreover, the structure of the slide rail component 1000 can be better avoided from being complicated, the mass of the slide rail component 1000 can be reduced, and the lightweight design of the vehicle can be facilitated.
[0049] Please refer to Figures 2-4 ,Figure 2 Structure diagram of a first implementation of the slide rail assembly; Figure 3 Structure diagram of a second implementation of the slide rail assembly; Figure 2 Force analysis diagram of the slide rail assembly when force causes peeling; Figure 4 Force analysis diagram of a slide rail assembly in the prior art when force causes peeling.
[0050] As shown in the drawings, Figure 2 In the embodiment of the present application, the upper rail component 1100 includes an upper rail top plate 1110, two upper rail side plates 1120, and two upper rail outer flanges 1130. The lower rail component 1200 includes a lower rail bottom plate 1210 and two lower rail side portions 1220, which 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, i.e., there can 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, i.e., there can also be a bend between the lower rail inner flange 1223 and the lower rail top plate 1222.
[0051] The two upper rail outer flanges 1130 can be inserted into the two lower rail side portions 1220 along the first direction X, respectively. Moreover, the extension direction of at least a part of the end of the upper rail outer flange 1130 (direction of the hollow arrow) Figure 2 can point to the lower rail top plate 1222, or the extension direction of at least a part of the end of the upper rail outer flange 1130 can point to the connection between the lower rail top plate 1222 and the lower rail inner flange 1223. It should be understood that the end of the upper rail outer flange 1130 specifically refers to the end of the upper rail outer flange 1130 away from the connection with the upper rail side plate 1120; the end can be a flat plate structure, in which case the extension direction of the end is the extension direction of the flat plate structure, or the end can also be a curved plate structure, in which case the extension direction of the end is the tangent direction of the curved plate structure.
[0052] In combination with Figure 3When the vehicle collides and the upper rail component 1100 and the lower rail component 1200 are separated, at least part of the end of the upper rail outer turning edge 1130 can directly act on the lower rail top plate 1222 or the joint of the lower rail top plate 1222 and the lower rail inner turning edge 1223. At this time, if the upper rail component 1100 and the lower rail component 1200 are to be separated, the upper rail component 1100 needs to drive the lower rail top plate 1222 to turn relative to the lower rail side plate 1221 and needs to drive the lower rail inner turning edge 1223 to turn relative to the lower rail top plate 1222, that is, to overcome two bends in the lower rail component 1200. The upper rail outer turning edge 1130 as a whole is subjected to the first deformation force F1 of the lower rail component 1200 in the third direction Z downward, and the size of the moment of the first deformation force F1 is L1.
[0053] Further combined Figure 4 The existing rail assembly is analyzed. As shown in Figure 4 For the existing rail assembly, the extension direction of the end of the upper rail outer turning edge 1130' is directed to the lower rail inner turning edge 1223'. When the vehicle collides and the upper rail component 1100' and the lower rail component 1200' are separated, the end of the upper rail outer turning edge 1130' can directly act on the lower rail inner turning edge 1223'. At this time, if the upper rail component 1100' and the lower rail component 1200' are to be separated, the upper rail component 1100' needs to drive the lower rail inner turning edge 1223' to turn relative to the lower rail top plate 1222', that is, to overcome one bend in the lower rail component 1200'. The upper rail outer turning edge 1130' as a whole is subjected to the second deformation force F2 of the lower rail component 1200' in the second direction Y, and the size of the moment of the second deformation force F2 is L2, which is obviously larger than L1.
[0054] According to the comparative analysis, in the embodiment of the utility model, the structure and shape of the upper rail component 1100 are adjusted. When the collision occurs, the number of bends of the lower rail component 1200 that need to be overcome when the upper rail component 1100 and the lower rail component 1200 are separated is more, the difficulty of deformation of the lower rail component 1200 is relatively high, and the size L1 of the moment of the first deformation force F1 that the upper rail outer turning edge 1130 is subjected to is relatively small, so that the difficulty of deformation of the upper rail outer turning edge 1130 is also relatively high. Therefore, the difficulty of separation of the upper rail component 1100 and the lower rail component 1200 in the embodiment of the utility model is relatively high as a whole, so that the anti-inclined strength of the rail assembly 1000 can be improved.
[0055] In some optional implementations, as shown in Figure 2 The upper rail outer turning edge 1130 and the lower rail side plate 1221 can both be a bent plate structure, so as to improve the structural strength of the upper rail component 1100 and the lower rail component 1200 to a greater extent.
[0056] 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 together. 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, i.e. 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, i.e. 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.
[0057] The first lower rail plate body 1221A, the second lower rail plate body 1221B and the third lower rail plate body 1221C can all be flat plate structures. Alternatively, at least one of the first lower rail plate body 1221A, the second lower rail plate body 1221B and the third lower rail plate body 1221C can be a curved plate structure.
[0058] The upper rail outer flange 1130 can include a first upper rail plate body 1131, a second upper rail plate body 1132 and a third upper rail plate body 1133. The first upper rail plate body 1131 is connected to the upper rail side plate 1120, the second upper rail plate body 1132 connects the first upper rail plate body 1131 and the third upper rail plate body 1133. The first upper rail plate body 1131, the second upper rail plate body 1132 and the third upper rail plate body 1133 can also be arranged at an angle between each other, i.e. there can be a bend between each other.
[0059] The first upper rail plate body 1131, the second upper rail plate body 1132 and the third upper rail plate body 1133 can all be flat plate structures. Alternatively, at least one of the first upper rail plate body 1131, the second upper rail plate body 1132 and the third upper rail plate body 1133 can be a curved plate structure.
[0060] It should be understood that the above description of the specific structure of the upper rail outer flange 1130 and the lower rail side plate 1221 is only an exemplary description made by the embodiments of the present application in combination with the drawings, and cannot be used as a limitation on the implementation scope of the sliding rail assembly 1000 provided by the embodiments of the present application. The upper rail outer flange 1130 and the lower rail side plate 1221 can also adopt other structure forms under the condition of meeting the function. For example, at least one of the upper rail outer flange 1130 and the lower rail side plate 1221 can only include two plate bodies, or at least one of the upper rail outer flange 1130 and the lower rail side plate 1221 can include at least four plate bodies. Figure 2
[0061] In some optional implementations, the slide rail assembly 1000 provided by the utility model can further include a rolling support component 1300.
[0062] The rolling support component 1300 can include a first rolling ball 1310 and a second rolling ball 1320. The first rolling ball 1310 can be located on the upper side of the second rolling ball 1320. Both the first rolling ball 1310 and the second rolling ball 1320 can be rolling arranged between the upper rail outer flange 1130 and the lower rail side plate 1221.
[0063] In combination with the foregoing detailed description of the upper rail outer flange 1130 and the lower rail side plate 1221, the first rolling ball 1310 can be specifically arranged between the third upper rail plate body 1133 and the third lower rail plate body 1221C, and the second rolling ball 1320 can be specifically arranged between the first upper rail plate body 1131 and the first lower rail plate body 1221A. The second rolling ball 1320 can be used to support the upper rail component 1100, so as to ensure the posture of the upper rail component 1100 relative to the lower rail component 1200. Moreover, both the first rolling ball 1310 and the second rolling ball 1320 can be used to eliminate the gap between the upper rail component 1100 and the lower rail component 1200 in the second direction Y and the third direction Z, so as to reduce the possibility of shaking of the upper rail component 1100 in the process of sliding relative to the lower rail component 1200.
[0064] In the utility model embodiment, the first rolling ball 1310 and the second rolling ball 1320 cooperate with each other and can both be used to improve the smoothness of the sliding of the upper rail component 1100 in the lower rail assembly 1200.
[0065] The number of the first rolling ball 1310 and the second rolling ball 1320 is not limited here and can be adjusted as needed. It should be understood that the assembly relationship between the first rolling ball 1310 and the second rolling ball 1320 and the upper rail outer flange 1130 and the lower rail side plate 1221 is an interference fit, so that the first rolling ball 1310 and the second rolling ball 1320 can ensure relatively close contact with the upper rail outer flange 1130 and the lower rail side plate 1221.
[0066] Please continue to refer to Figure 2 In the upper rail outer flange 1130, the first upper rail plate body 1131 can be tangent to the outer wall surface of the second rolling ball 1320 through a curved surface, so as to better install and limit the second rolling ball 1320, improve the installation reliability of the second rolling ball 1320, and better play the function of eliminating the gap of the second rolling ball 1320. In the lower rail side plate 1221, the first lower rail plate body 1221A can be tangent to the outer wall surface of the second rolling ball 1320 through a plane, so as to improve the smoothness of the rolling of the second rolling ball 1320.
[0067] Similarly, in the upper rail outer flange 1130, the third upper rail plate 1133 can be tangent to the outer wall surface of the first ball 1310 through its arc surface, so as to better limit the installation of the first ball 1310, improve the installation reliability of the first ball 1310, and better utilize the function of the first ball 1310 in eliminating gaps. In the lower rail side plate 1221, the third lower rail plate 1221C can be tangent to the outer wall surface of the first ball 1310 through its plane, so as to improve the smoothness of the rolling of the first ball 1310.
[0068] In some alternative implementations, the top surface of the upper rail top plate 1110 can be flat. This allows for a simpler structure of the upper rail top plate 1110, simplifying the structure of the upper rail component 1100 and reducing costs. It also makes it easier for the upper rail top plate 1110 to be connected to the seat body through different installation methods.
[0069] For example, as mentioned above Figure 1 As shown, a connecting post 1140 can be provided on the top surface of the upper rail top plate 1110. Specifically, the connecting post 1140 can be a rivet post, etc.
