[0003] The present application relates to the technical field of seat components, and in particular to a locking spring, a slide rail assembly, a seat and a vehicle. Background Art

[0004] The seat rail is the core connecting component between the seat and the vehicle floor. Its primary function is to adjust the fore-and-aft position of the seat and provide a seatbelt interface, ensuring both user comfort and passenger safety. The seat rail's locking mechanism must ensure seat safety, especially during accidents such as vehicle collisions, where the seat is subject to significant inertial forces.

[0005] Summary of the Invention

[0006] The present application provides a locking spring, a slide rail assembly, a seat and a vehicle to solve at least one of the above-mentioned technical problems.

[0007] A locking spring piece of the present application is applied to a slide rail, wherein the locking spring piece is provided with a connecting hole, and an inner wall of the connecting hole is provided with a first tooth portion, wherein the first tooth portion includes at least one tooth, and the at least one tooth of the first tooth portion is protruding from the inner wall of the connecting hole;

[0008] The connecting hole is configured to allow a connecting piece of the slide rail to pass through, and allows the connecting piece to abut against the first tooth portion.

[0009] The above-mentioned locking spring piece, by arranging the first tooth portion in the connecting hole, can interact with the teeth of the first tooth portion during assembly, thereby improving the limiting effect of the connecting piece on the locking spring piece, making it less likely for the locking spring piece to move and rotate, and improving the safety and stability of the locking spring piece when it moves relative to the slide rail.

[0010] In some embodiments, the first tooth portion includes at least two teeth, and the at least two teeth of the first tooth portion are arranged on the inner wall of the connecting hole along the circumference of the connecting hole. In this way, the abutment strength of the connecting member against the inner wall of the connecting hole can be improved.

[0011] In some embodiments, the inner wall of the connecting hole includes a first plane extending along the length of the locking spring, and the at least one tooth of the first tooth portion protrudes from the first plane. This can reduce shaking of the locking spring when it moves along the length.

[0012] In some embodiments, the inner wall of the connecting hole includes a second plane disposed opposite to the first plane, and the at least one tooth is disposed on both the first plane and the second plane. In this way, the effect of reducing the shaking amplitude of the locking spring can be enhanced.

[0013] In some embodiments, the connecting hole is a waist-shaped hole, and two opposite inner side walls of the waist-shaped hole are respectively formed as the first plane and the second plane. In this way, since the processing technology of the waist-shaped hole is relatively simple, it can be facilitated to process.

[0014] In some embodiments, the connecting member is disposed on the first slideway of the slide rail, so that the locking elastic sheet is limitedly connected to the slide rail.

[0015] In some embodiments, at least a portion of the connector is configured to elastically deform when abutting the first tooth portion. This allows the connector to elastically deform to fill gaps around the teeth of the first tooth portion, thereby enhancing the connector's ability to restrict the locking spring.

[0016] A slide rail assembly of the present application includes:

[0017] The locking spring as described in any one of the above embodiments;

[0018] a slide rail, the slide rail comprising a first slide track, and;

[0019] A connecting piece is provided on the first slideway, the connecting piece passes through the connecting hole, and the connecting piece abuts against the first tooth portion.

[0020] The above-mentioned locking spring piece, by arranging the first tooth portion in the connecting hole, can interact with the teeth of the first tooth portion during assembly, thereby improving the limiting effect of the connecting piece on the locking spring piece, making it less likely for the locking spring piece to move and rotate, and improving the safety and stability of the locking spring piece when it moves relative to the slide rail.

[0021] In certain embodiments, the slide rail is provided with a fixing hole, and the connecting member passes through the fixing hole and the connecting hole, so that the locking elastic sheet is limitedly connected to the slide rail.

[0022] In some embodiments, the connecting hole extends longer along the length of the locking spring than the fixing hole does along the length of the locking spring, so that the connecting hole can absorb the tolerance of the locking spring along the movable direction during assembly.

[0023] In some embodiments, the slide rail assembly includes:

[0024] A snap-on portion, one end of the locking elastic piece forms the snap-on portion, and the snap-on portion includes a paddle member, and;

[0025] An operating handle, the operating handle comprising a handle end and a notch, the operating handle being connected to the locking spring through the handle end;

[0026] The snap-fastener is configured to elastically abut the notch of the operating handle via the paddle element to limit the movement of the handle end along the direction in which the locking spring is inserted, thereby reducing positional deviation of the operating handle along the insertion direction.

[0027] In some embodiments, the snap-on portion includes an arcuate arm, a first straight arm, and a second straight arm. The arcuate arm is bent and extended from the locking spring. The arcuate arm, the first straight arm, the second straight arm, and the paddle piece are sequentially connected to form a bent structure.

[0028] In some embodiments, the first straight arm, the second straight arm, and the paddle member are located in the same plane;

[0029] The locking elastic piece includes a fixing portion, the fixing portion is provided with the connecting hole, and the arc-shaped arm is connected to the fixing portion;

[0030] The locking spring is configured such that the angle formed by the first plane and the second plane ranges from 10° to 30°. The first plane is the plane where the first straight arm, the second straight arm, and the paddle element are located, and the second plane is the plane where the fixing portion is located. This helps ensure the snap-fastening effect of the snap-fastening portion.

[0031] A seat of the present application comprises:

[0032] seat body, and;

[0033] In the slide rail assembly described in any one of the above embodiments, the seat body is fixedly connected to the first slide rail.

[0034] The above-mentioned seat, by arranging the first tooth portion in the connecting hole, the connecting member can interact with the teeth of the first tooth portion during assembly, which can improve the limiting effect of the connecting member on the locking spring plate, making it less likely for the locking spring plate to move and rotate, and can improve the safety and stability of the locking spring plate when it moves relative to the slide rail.

[0035] A vehicle of the present application comprises:

[0036] The seat described in the above embodiment; or the slide rail assembly described in any one of the above embodiments.

[0037] The above-mentioned vehicle, by arranging the first tooth portion in the connecting hole, the connecting member can interact with the teeth of the first tooth portion during assembly, which can improve the limiting effect of the connecting member on the locking spring plate, making it less likely for the locking spring plate to move and rotate, and can improve the safety and stability of the locking spring plate when it moves relative to the slide rail.

[0063] In the description of this application, some of the disclosed contents are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The contents described below with reference to the accompanying drawings are illustrative and are only used to explain this application, and are not to be construed as limiting this application.

[0064] In the description of the present application, many different contents or examples are disclosed to implement different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0065] In addition, the present application may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate a relationship between the various situations and / or settings discussed.

[0066] The seat rail is the core connecting component between the seat and the vehicle floor. Its primary function is to adjust the fore-and-aft position of the seat and provide a seatbelt interface, ensuring both user comfort and passenger safety. The seat rail's locking mechanism must ensure seat safety, especially during accidents such as vehicle collisions, where the seat is subject to significant inertial forces.

[0067] In the related art, the basic principle of the manual seat slide is to provide a locking tooth between the first slide tooth window and the second slide tooth groove of the slide. In the locked state, the locking tooth restricts the movement of the first and second slides. By pulling the operating handle, the locking spring installed inside the slide is driven to rotate, thereby driving the locking tooth at the end of the locking spring handle to move in the unlocking direction, and the locking tooth disengages from the second slide tooth groove to unlock the second slide. When the operating handle is released, the operating handle is reset under the action of the elastic force of the locking spring, and the locking tooth on the locking spring returns to the locked position, thereby restricting the movement of the first slide relative to the second slide. The locking spring needs to ensure the locking reliability between the first and second slides to eliminate the gap between the first and second slides, and also needs to ensure that the movement of the operating handle, locking spring and other components during the unlocking and locking process is free of friction noise and vibration.

[0068] Referring to Figures 1 and 2, the slide rail assembly 100 of the embodiment of the present application may include a locking spring 10. The locking spring 10 may include at least one of a fixing portion 11, a first bent portion 12, and a locking portion 13. The locking spring 10 may be connected to a first component via the fixing portion 11. The locking spring 10 may achieve a locking effect and an unlocking effect on the first component via the locking portion 13. The locking spring 10 may be connected to a second component via the first bent portion 12. The first component and the second component may each have different structures other than the locking spring 10.

[0069] In Figures 1 and 2, directions A1 and A2 may respectively represent length directions of the locking spring 10, directions A3 and A4 may respectively represent height directions of the locking spring 10, and directions A5 and A6 may respectively represent width directions of the locking spring 10.

[0070] 1 and 2 , the fixing portion 11 may be located on a side of the locking spring 10 closer to the direction A1 . The fixing portion 11 on the locking spring 10 tends to be closer to the direction A3 than to the direction A4 .

[0071] The fixing portion 11 can be an entire plate-like structure. The fixing portion 11 can have a connection hole 111. The connection hole 111 can be provided on the plate-like structure of the fixing portion 11. The connection hole 111 can have a waist-shaped structure, or in other words, the hole diameter of the connection hole 111 can be inconsistent, such that the hole diameter of the connection hole 111 in one direction is larger than the hole diameter in other directions. In Figure 1, the connection hole 111 can extend along the A1 direction and the A2 direction.

[0072] The first component may include a fixing hole 45. The defined connection between the locking spring 10 and the first component may be achieved by a defined connection between the connecting hole 111 and the fixing hole 45. Specifically, the connecting hole 111 and the fixing hole 45 may be connected by corresponding structures. Because the connecting hole 111 has an extended length, although the fixing portion 11 is limited by the corresponding structure, the fixing portion 11 can still move relative to the first component along the A1 direction and the A2 direction. The corresponding structure that penetrates the connecting hole 111 and the fixing hole 45 may be a rivet, or in other words, the first component and the locking spring 10 may be defined and connected by riveting.

[0073] Based on the above content about the connecting hole 111, when the locking spring 10 is assembled to the first component, the connecting hole 111 can adapt to the tolerance effect (such as the tolerance of the structure itself and the tolerance caused by slight differences in the assembly position) through its own extended length, thereby achieving the effect of eliminating the tolerance effect.

[0074] The fixing portion 11 may include a first tooth portion 112. In FIG1 , the first tooth portion 112 may be disposed on a sidewall extending along the A1 and A2 directions within the connecting hole 111. The sidewall extending along the A1 and A2 directions within the connecting hole 111 may be located on one side of the connecting hole 111 in the A5 direction and / or on one side of the connecting hole 111 in the A6 direction. The sidewall of the connecting hole 111 may be referred to as an inner wall 1110 of the connecting hole 111. The sidewall extending along the A1 and A2 directions within the connecting hole 111 may be a flat surface.

[0075] The first tooth portion 112 may include at least one tooth 1121. The tooth 1121 of the first tooth portion 112 may extend along the A3 direction and the A4 direction. When the first tooth portion 112 includes multiple teeth 1121, the multiple teeth 1121 of the first tooth portion 112 may be arranged sequentially along the A1 direction and the A2 direction. The teeth 1121 of the first tooth portion 112 may be protrusions formed on the inner wall 1110 of the connection hole 111.

[0076] Based on the above content about the first tooth portion 112, when the fixing portion 11 needs to move relative to the first component, the fixing portion 11 will move along the A1 direction and the A2 direction relative to the corresponding structure of the connecting hole 111, and during the movement, the side wall of the connecting hole 111 provided with the first tooth portion 112 will abut against the corresponding structure of the connecting hole 111.

[0077] Because the teeth 1121 of the first tooth portion 112 protrude relatively from the inner wall 1110 of the connecting hole 111, the corresponding structure penetrating the connecting hole 111 is more likely to contact the teeth 1121 of the first tooth portion 112 within the connecting hole 111, generating friction, thereby limiting the movement of the locking spring 10 through the generated friction. In some cases, the corresponding structure penetrating the connecting hole 111 can undergo plastic deformation after being compressed, causing material flow. The resulting deformation can match the teeth 1121 of the first tooth portion 112, thereby filling the gaps around the teeth 1121 of the first tooth portion 112. This can increase the contact area between the corresponding structure penetrating the connecting hole 111 and the inner wall 1110 of the connecting hole 111, making the interaction effect of the increased force between the corresponding structure penetrating the connecting hole 111 and the inner wall 1110 of the connecting hole 111 more significant, thereby limiting the movement of the locking spring 10.

[0078] After the locking spring 10 is assembled to the first assembly, the positional offset of the locking spring 10 can be reduced, thereby improving the stability of the locking spring 10 during movement, and ultimately reducing the movement and rotation of the locking spring 10 during movement. The positional offset of the locking spring 10 can include movement of the locking spring 10 along the A1 direction or the A2 direction, and can also include rotation of the locking spring 10 around the A1 direction or the A2 direction.

[0079] In addition, the fixing portion 11 may be a substantially square, circular, oval or waist-shaped plate-shaped structure.

[0080] 1 and 2 , the first bending portion 12 may be connected to an end of the fixing portion 11 close to the A2 direction. The first bending portion 12 may extend from the fixing portion 11 toward the A4 direction, so that the first bending portion 12 may be bent relative to the fixing portion 11.

[0081] The first bent portion 12 may have a first opening 122. The first opening 122 may be located in the middle of the first bent portion 12 along the A5 and A6 directions. The first opening 122 may also be located along the A1 and A2 directions. The first opening 122 allows for the second component to pass through, thereby facilitating a defined connection to the first bent portion 12.

[0082] The first bending portion 12 may include a tongue-shaped member 123. The tongue-shaped member 123 may be a structure that extends outward relative to other structures of the first bending portion 12. In Figures 1 and 2, the tongue-shaped member 123 may be located on the side of the locking spring 10 close to the A4 direction. The A4 direction may be the bottom direction of the locking spring 10. The tongue-shaped member 123 may have elastic force. When the locking spring 10 is connected to the second component through the first bending portion 12, the tongue-shaped member 123 may abut against the second component at the bottom of the second component through elastic force, so that the second component can be stuck in the first opening 122, which can improve the abutment and fixing effect of the first bending portion 12 on the second component.

[0083] 1 and 2 , the locking portion 13 may be connected to an end of the first bending portion 12 near the A4 direction. The locking portion 13 may extend from the first bending portion 12 along the A2 direction, so that the first bending portion 12 may be bent relative to the locking portion 13 .

[0084] The locking portion 13 may include a second tooth portion 131. The second tooth portion 131 may be located on a side of the locking portion 13 that faces the A2 direction. The second tooth portion 131 may include at least two teeth 1121. The teeth 1121 of the second tooth portion 131 may be spaced apart on a side of the locking portion 13 that faces the A5 direction and / or the A6 direction.

[0085] The locking spring 10 can rotate around the A5 direction and the A6 direction to enable the teeth 1121 of the second tooth portion 131 to move to different positions. The first component can be provided with a tooth groove 51.

[0086] When the locking spring clip 10 rotates around the A1 direction and the A2 direction, the tooth 1121 of the second tooth portion 131 can be rotated and moved into the tooth groove 51 of the first component, so that the first component and the locking spring clip 10 are mutually restricted by the tooth groove 51 of the first component and the tooth 1121 of the second tooth portion 131, thereby achieving the effect of locking the first component by the locking spring clip 10.

[0087] When the locking spring piece 10 rotates around the A1 direction and the A2 direction, the tooth 1121 of the second tooth portion 131 can also be rotated out of the tooth groove 51 of the first component, so as to release the mutual restriction between the first component and the locking spring piece 10 through the tooth groove 51 of the first component and the tooth 1121 of the second tooth portion 131, thereby achieving the effect of unlocking the first component by the locking spring piece 10.

[0088] The second tooth portion 131 can be integrally formed on the locking spring piece 10 , which can improve the integration level between different structures and is also beneficial to improving the structural strength of the second tooth portion 131 .

[0089] In Figures 1 and 2 , the locking spring 10 may include a snap-on portion 14. The snap-on portion 14 may be located on a side of the locking spring 10 close to the direction A1. The snap-on portion 14 may extend from the fixing portion 11 toward the direction A1.

[0090] In Figures 1 and 2, the snap-on portion 14 may include an arcuate arm 141, a first straight arm 142, a second straight arm 143, and a paddle element 144. One end of the arcuate arm 141 may be connected to the fixed portion 11. The other end of the arcuate arm 141 may be connected to the first straight arm 142. The first straight arm 142 may be connected to the second straight arm 143, and the respective extension directions of the first straight arm 142 and the second straight arm 143 may be parallel to each other. The extension direction of the first straight arm 142 may be parallel to the A1 direction and the A2 direction. The extension direction of the second straight arm 143 may be parallel to the A1 direction and the A2 direction. The paddle element 144 may be connected to one end of the second straight arm 143.

[0091] In Figures 1 and 2 , the snap-on portion 14 may include a third straight arm 145. The first straight arm 142 may be connected to the second straight arm 143 via the third straight arm 145. The first straight arm 142, the second straight arm 143, the third straight arm 145, and the paddle element 144 may be located in the same plane. The different structures may be located in the same plane, and the respective extension directions of the structures may be located in the same plane.

[0092] In some cases, the first straight arm 142, the second straight arm 143 and the paddle member 144 are located in the same plane. When the paddle member 144 is subjected to force, the force applied to the paddle member 144 can be evenly transmitted to the first straight arm 142 and the second straight arm 143, so as to increase the force threshold of the snap portion 14 and improve the structural strength of the snap portion 14.

[0093] In FIG2 , the plane in which the first straight arm 142, the second straight arm 143, and the paddle element 144 are located is denoted as F1. The plane in which the fixing element is located due to its plate-like structure is denoted as F2. The angle between planes F1 and F2 is denoted as a.

[0094] The snap-action portion 14 can be used to fix the corresponding structure by means of a clamping and abutting method. In Figures 1 and 2, the paddle piece 144 can be located near the first opening 122. When the corresponding structure needs to pass through the first opening 122, it may be necessary to use its own structure to push away the paddle piece 144 to make room for the first opening 122 to be penetrated. Due to the structural coordination of the arc-shaped arm 141, the first straight arm 142, the second straight arm 143 and the paddle piece 144, an elastic force can be generated. After the first opening 122 is penetrated, the paddle piece 144 can be abutted against the surface of the corresponding structure through the elastic force, so that the snap-action portion 14 can be clamped and abutted against the corresponding structure that penetrates the first opening 122 through the paddle piece 144, thereby achieving the effect of snap-action fixing of the snap-action portion 14.

[0095] The value range of angle a can be between 10° and 30°. The change of angle a can affect the snapping effect of the snap fastener. It is understandable that if angle a is too small, the first straight arm 142, the second straight arm 143 and the paddle member 144 will be closer to the plane F2 as a whole. When the paddle member 144 is used to achieve the abutment and fixation effect, the paddle member 144 may not protrude significantly, resulting in unstable abutment, thereby reducing the abutment and fixation effect. If angle a is too large, the first straight arm 142, the second straight arm 143 and the paddle member 144 will be further away from the plane F2 as a whole. When the paddle member 144 is used to achieve the abutment and fixation effect, the paddle member 144 may be too protruding, causing the corresponding structure to be abutted to be unable to reach a position where it can be abutted by the paddle member 144, thereby failing to achieve the abutment and fixation effect.

[0096] In addition, the first straight arm 142 , the second straight arm 143 and the paddle member 144 are located in the same plane, which is beneficial to the structural formation of the snap fastener.

[0097] In Figures 1 and 2 , the locking spring 10 may include a second bent portion 15. The second bent portion 15 may be connected to the side of the locking portion 13 that is closer to the A2 direction. The second bent portion 15 may extend in the A3 direction relative to the locking portion 13, so that the second bent portion 15 is bent relative to the locking portion 13.

[0098] In Figures 1 and 2, the second bend portion 15 may include a bend transition section 151. Along the A3 direction, the cross-sectional dimensions of the bend transition section 151 decrease sequentially. In other words, the bend transition section 151 is tilted along the sides of the A5 and A6 directions, respectively, such that the two sides tend to approach each other along the A3 direction.

[0099] In Figures 1 and 2 , the second bending portion 15 may include a bending member 152. The bending member 152 may be connected to the side of the bending transition section 151 that is close to the A3 direction. The bending member 152 may extend from the bending transition section 151 to a direction away from the bending transition section 151. The portion of the bending member 152 close to the bending transition section 151 may extend along the A3 direction, while the portion of the bending member 152 away from the bending transition section 151 may extend along the A2 direction, allowing the bending member 152 to be in a bent state.

[0100] In Figures 1 and 2 , the locking spring 10 may include a silencer 16. The silencer 16 may be positioned on the locking portion 13, near one side in the direction A2. When the corresponding structure abuts against the silencer 16, the silencer 16 can offset vibrations or noise generated by the movement of the corresponding structure, making the movement of the corresponding structure quieter relative to the movement of the locking spring 10.

[0101] The silencer 16 may be in a circular structure, which can improve the effect of uniform load bearing.

[0102] Please refer to Figure 3, the slide rail assembly 100 of the present application may include an operating handle 20. The operating handle 20 may include a handle end 21, an end transition section 22 and a cutout 23. The handle end 21 may be located at the end of the operating handle 20. The end transition section 22 may be adjacent to the handle end 21. Along the extension direction of the operating handle 20 at the end, the end transition section 22 may have changes and transitions in cross-sectional dimensions. In some cases, the changes and transitions in cross-sectional dimensions of the end transition section 22 may include transitioning from a circular cross section to a square cross section. In Figure 3, the B1 direction and the B2 direction may be represented as the extension directions of the ends of the operating handle 20.

[0103] In FIG. 3 , the operating handle 20 may be in a U-shaped structure as a whole, or in other words, ends may be formed on both sides of the operating handle 20 , and the ends on both sides may be mirror-symmetrical on the operating handle 20 .

[0104] The operating handle 20 may include an operating portion 24. The operating portion 24 may be located in the middle portion between the two ends of the operating handle 20. The user may hold the operating portion 24, thereby enabling the ends of the operating handle 20 to move along the B1 direction and the B2 direction.

[0105] Based on the above, the operating handle 20 of the present application can be the second component. The operating handle 20 can interact with the locking spring 10 through the handle end 21, the end transition section 22 and the notch 23, so that the operating handle 20 can be limitedly connected to the locking spring 10.

[0106] Specifically, the operating handle 20 can pass through the first opening 122 of the first bending portion 12 through the handle end 21. When the handle end 21 abuts against the position of the silencer 16, the end transition section 22 can abut against the side wall of the first opening 122, and the cutout 23 can abut against the paddle piece 144 of the snap portion 14, thereby limiting the movement space of the operating handle 20 along the direction of passing through the first opening 122 and completing the assembly of the operating handle 20.

[0107] After the operating handle 20 is assembled, the paddle 144 provides a certain amount of resilience for the movement of the operating handle 20, thereby making the overall structure of the operating handle 20 more stable after assembly. The paddle 144 and the silencer 16 can be located on either side of the locking spring 10, which helps to better balance the force applied to the operating handle 20 after assembly.

[0108] Referring to Figures 4 to 6 , the slide rail assembly 100 of the present application may include a slide rail 30. The locking spring 10 may be connected to the slide rail 30, thereby integrally connecting the locking spring 10 and the slide rail 30. When the locking spring 10 is driven to move, the slide rail 30 may also be driven to move.

[0109] In FIG. 4 to FIG. 6 , directions C1 and C2 may represent length directions of the slide rail 30 , directions C3 and C4 may represent height directions of the slide rail 30 , and directions C5 and C6 may represent width directions of the slide rail 30 .

[0110] The operating handle 20 of the present application can be limited to connect with the locking spring 10. The user can operate the operating handle 20, thereby driving the slide rail 30 to move along the movement direction of the handle end 21 of the operating handle 20.

[0111] The slide rail 30 can be fixedly connected to the object to be adjusted so that the object to be adjusted can be moved. The object to be adjusted can include a seat. In other words, the locking spring 10, the operating handle 20, and the slide rail 30 of the present application can cooperate to move the seat to achieve the effect of adjusting the seat position. The seat can be a car seat.

[0112] In Figures 4 to 6, the slide rail 30 may include a first slide 40. The first slide 40 may extend along the C1 direction and the C2 direction. The first slide 40 may have a semi-enclosed structure. The locking spring 10 may be confined within the space formed by the first slide 40. The first slide 40 may have outwardly curved structures on both sides along the C5 direction and the C6 direction, respectively. Along the C1 direction and the C2 direction, the structure of the first slide 40 may be roughly "Ω"-shaped, i.e., the first slide 40 shown in Figure 6.

[0113] In Figures 4 to 6, the first slideway 40 may be provided with a tooth window 42. In Figure 6, the tooth window 42 may be provided on the side of the first slideway 40 along the C5 direction and / or the C6 direction. In Figure 4, the tooth window 42 may be a hole-like structure. The side of the first slideway 40 along the C5 direction and / or the C6 direction may be formed with a folding structure. The tooth window 42 may be formed on the folding structure of the first slideway 40, thereby allowing other structures to enter the tooth window 42 from different directions.

[0114] The side of the first slideway 40 may be provided with at least two spaced-apart tooth windows 42. The tooth windows 42 may correspond to the second tooth portions 131 of the locking portion 13. In other words, the teeth 1121 of the second tooth portion 131 may slide into a corresponding tooth window 42. The second tooth portion 131 and the tooth window 42 cooperate to achieve mutual restraint and transmission between the locking spring 10 and the first slideway 40. By coordinating the connecting hole 111 and the first tooth portion 112, the relative positions of the second tooth portion 131 and the tooth window 42 can be precisely determined.

[0115] In some cases, the first component may be a slide rail 30, and the second component may be an operating handle 20. The operating handle 20 may be connected to the locking spring 10 through a partial structure, and the locking spring 10 may be inserted into the tooth window 42 of the first slide 40 through the second tooth portion 131, so that the first slide 40 can be moved by the operating handle 20.

[0116] In Figures 4 to 6 , the slide rail 30 may include a travel limiter 43. In Figure 4 , the travel limiter 43 may be positioned on one side of the first slideway 40 along the C4 direction. One of the travel limiters 43 may be positioned on the side where all the tooth windows 42 lie in the C1 direction, and the other travel limiter 43 may be positioned on the side where all the tooth windows 42 lie in the C2 direction. When the first slideway 40 moves relative to the first slideway 40, the two travel limiters 43 may respectively limit the travel of the first slideway 40 along the C1 direction or the C2 direction.

[0117] In Figures 4 to 6 , the first slideway 40 may be provided with a second opening 44. The second opening 44 may be located on one side of the first slideway 40 along the C3 direction. When the locking spring 10 is confined within the first slideway 40, the bent member 152 of the second bent portion 15 of the locking spring 10 may extend through the second opening 44 from within the first slideway 40, thereby enabling the bent member 152 to abut or drive other structures outside the first slideway 40.

[0118] In Figures 4 to 6 , the first slideway 40 may be provided with a fixing hole 45. The fixing hole 45 may be provided on one side of the first slideway 40 along the C3 direction. The fixing hole 45 may cooperate with the connecting hole 111 of the fixing portion 11 of the locking spring 10. Specifically, the fixing hole 45 and the connecting hole 111 may be mutually defined. As previously discussed regarding the connecting hole 111, the structure defining the connecting hole 111 can move relative to the sidewall of the connecting hole 111, allowing the locking spring 10 to move relative to the first slideway 40.

[0119] In FIG. 4 to FIG. 6 , the first slideway 40 may be provided with fixing holes 45 at different positions, so as to be adaptable to locking elastic pieces 10 of different sizes.

[0120] In Figures 4 to 6 , the slide rail 30 may include an elastic stopper 46. The elastic stopper 46 may be disposed on one side of the first slideway 40 along the C3 direction. When the corresponding structure is confined within the first slideway 40, the elastic stopper 46 may abut against it and exert a force on it through its own elastic force, thereby enabling the elastic stopper 46 to function as a stopper.

[0121] Please refer to Figure 5 , in which the locking spring 10 can be located within the first slideway 40, and the operating handle 20 can pass through the first opening 122 of the locking spring 10, so that the operating end can be located between the silencer 16 and the elastic stopper 46. When the operating handle 20 moves relative to the locking spring 10, the elastic stopper 46 can abut the operating end on one side, so that the other side of the operating end can maintain contact with the silencer 16. The silencer 16 can eliminate vibration or noise generated by the movement of the operating end, so that the locking spring 10 and the slideway 30 can cooperate to reduce the vibration or noise generated by the operating handle 20.

[0122] In addition, the cooperation between the silencer 16 and the elastic limiting member 46 can also limit the rotational movement of the handle end 21.

[0123] 5 , the slide rail 30 may include a connector 31 . The joint arrangement of the fixing hole 45 and the connector hole 111 may be achieved through the connector 31 .

[0124] 5 and 6 , the slide rail 30 of the present application may include a second slideway 50. The second slideway 50 may slide relative to the first slideway 40, thereby cooperating with the first slideway 40 to form the slide rail 30 structure.

[0125] In FIG. 5 and FIG. 6 , directions C1 and C2 may represent length directions of the second slideway 50 , directions C3 and C4 may represent height directions of the second slideway 50 , and directions C5 and C6 may represent width directions of the second slideway 50 .

[0126] In Figures 5 and 6 , the second slideway 50 can extend along the C1 and C2 directions. The two sides of the second slideway 50 along the C5 and C6 directions can be close to each other, forming a semi-enclosed structure. The two sides of the second slideway 50 along the C5 and C6 directions can each be inwardly curved. Along the C1 and C2 directions, the second slideway 50 can have a generally "ω" shape, i.e., the shape of the second slideway 50 shown in Figure 6 .

[0127] In some cases, the first component may be a slide rail 30, the second component may be an operating handle 20, the first slide 40 and the second slide 50 may be enclosed with each other, and the operating handle 20 may be inserted into the space formed by the first slide 40 and the second slide 50 through a partial structure.

[0128] In Figures 5 and 6 , the second slideway 50 may be provided with a tooth groove 51. The tooth groove 51 may be provided at the end of the second slideway 50. The end of the second slideway 50 may be formed along the end of the inwardly curved structure of the second slideway 50. In Figure 6 , the end of the second slideway 50 may be close to the space semi-enclosed by the second slideway 50, or in other words, the end of the second slideway 50 may be located inside the second slideway 50.

[0129] In FIG6 , the first slide 40 and the second slide 50 can cooperate with each other so that the tooth window 42 of the first slide 40 can match the tooth groove 51 of the second slide 50. When the locking spring 10 is connected to the second slide 50, the teeth 1121 of the second tooth portion 131 of the locking spring 10 can sequentially penetrate the tooth window 42 of the first slide 40 and the tooth groove 51 of the second slide 50, so that the first slide 40 and the second slide 50 are locked by the second tooth portion 131, thereby achieving a locking effect on the first slide 40.

[0130] FIG6 shows the slide rail 30 in a locked state, wherein the locking spring 10 is driven to move, causing the teeth 1121 of the second tooth portion 131 to move out of the tooth groove 51, thereby unlocking the first slide 40 and the second slide 50 and enabling relative movement. The relative movement between the first slide 40 and the second slide 50 corresponds to the slide rail 30 being in an unlocked state.

[0131] On the basis of the foregoing, the locking spring 10 , the operating handle 20 and the slide rail 30 of the present application can cooperate with each other, thereby realizing the locking and unlocking functions of the slide rail 30 .

[0132] Please refer to Figure 5. In some cases, the user can drive the operating handle 20 so that the handle end 21 can move toward the C4 direction. The handle end 21 will abut against the silencer 16, so that the handle end 21 can drive the portion of the locking portion 13 close to the silencer 16 to also move toward the C4 direction. Since the second tooth portion 131 is close to the silencer 16, the second tooth portion 131 can move toward the C4 direction. Before the second tooth portion 131 moves, it is in a state of penetrating the tooth window 42 and the tooth groove 51. After the second tooth portion 131 moves, it will move out of the tooth groove 51, allowing the first slide 40 and the lower slide to move relative to each other.

[0133] That is, when the handle end 21 moves toward the direction C4, the first slide 40 and the second slide 50 can be unlocked; conversely, when the handle end 21 moves toward the direction C3, the first slide 40 and the second slide 50 can be locked.

[0134] After unlocking the first and second slideways 40, 50, the user can again move the operating handle 20, allowing the handle end 21 to move in the C1 or C2 direction. Because the operating handle 20 is connected to the locking spring 10, and the locking spring 10 is connected to the first slideway 40, the first slideway 40 can be moved in the C1 or C2 direction. When the first slideway 40 is fixedly connected to the object to be adjusted, the object can be moved in the C1 or C2 direction via the first slideway 40.

[0135] When it is necessary to lock the first slide 40 and the second slide 50, the bending part 152 can be pulled to move in the A3 direction, thereby driving the second tooth portion 131 to move in the A3 direction and penetrate into the tooth window 42 of the first slide 40 and the tooth groove 51 of the second slide 50, so as to achieve locking of the first slide 40 and the second slide 50.

[0136] In addition, based on the above contents, the technical concept of this application can also be implemented through the following implementation methods.

[0137] Referring to Figures 1, 2, and 4, a locking spring 10 of the present application can be applied to a slide rail 30. The locking spring 10 can be provided with a connecting hole 111. The inner wall 1110 of the connecting hole 111 can be provided with a first tooth portion 112. The first tooth portion 112 can include at least one tooth 1121. The teeth 1121 of the first tooth portion 112 can be protruding from the inner wall 1110 of the connecting hole 111. The connecting hole 111 can be configured to allow the connecting member 31 of the slide rail 30 to pass through, so that the connecting member 31 can abut against the first tooth portion 112.

[0138] The above-mentioned locking spring piece 10, by setting the first tooth portion 112 in the connecting hole 111, the connecting member 31 can interact with the teeth 1121 of the first tooth portion 112 during assembly, thereby improving the limiting effect of the connecting member 111 on the locking spring piece 10, making it less likely for the locking spring piece 10 to move and rotate, and can improve the safety and stability of the locking spring piece 10 when it moves relative to the slide rail 30.

[0139] Please refer to FIG. 1 , the connecting member 31 may pass through the first slideway 40 of the slide rail 30 , so that the locking spring 10 is limited to connect with the slide rail 30 .

[0140] 1 , at least a portion of the connector 31 can be configured to elastically deform when abutting the first tooth portion 112. Thus, the elastic deformation of the connector 31 can fill the gaps around the teeth 1121 of the first tooth portion 112, thereby enhancing the limiting effect of the connector 31 on the locking spring 10.

[0141] 1 , the first tooth portion 112 may include at least two teeth 1121 . The at least two teeth 1121 of the first tooth portion 112 may be arranged on the inner wall 1110 of the connection hole 111 along the circumference of the connection hole 111 .

[0142] In this way, the contact strength of the connecting member 31 against the inner wall 1110 of the connecting hole 111 can be improved.

[0143] 1 , the connecting hole 111 may include a first plane 1111 . The first plane 1111 may extend along the length of the locking spring 10 . The at least one tooth 1121 of the first tooth portion 112 may protrude from the first plane 1111 .

[0144] In this way, the shaking of the locking spring 10 when it moves along the length direction can be reduced.

[0145] In Figure 1 , the extension direction of the first plane 1111 may correspond to the length direction of the connecting hole 111. When the locking spring 10 moves relative to the connecting member 31 along the length direction of the connecting hole 111, the connecting member 31 easily abuts against the teeth 1121 on the first plane 1111, thereby suppressing the shaking amplitude of the locking spring 10.

[0146] 1 , the inner wall 1110 of the connecting hole 111 may include a second plane 1112 disposed opposite to the first plane 1111. Both the first plane 1111 and the second plane 1112 are provided with at least one tooth 1121.

[0147] In this way, the effect of reducing the shaking amplitude of the locking spring 10 can be enhanced.

[0148] In Figure 1 , the first plane 1111 can be the wall structure of the inner wall 1110 of the connecting hole 111 on the side closer to the A5 direction, and the second plane 1112 can be the wall structure of the inner wall 1110 of the connecting hole 111 on the side closer to the A6 direction, so that the first plane 1111 and the second plane 1112 are arranged opposite each other. When the locking spring 10 moves relative to the connecting member 31 along the length of the connecting hole 111, the connecting member 31 can easily abut against the teeth 1121 on the first plane 1111 and the teeth 1121 on the second plane 1112, respectively, thereby suppressing the shaking amplitude of the locking spring 10 in two different directions.

[0149] The connecting hole 111 may be a waist-shaped hole, and two opposite inner sidewalls of the waist-shaped hole may be formed into a first plane 1111 and a second plane 1112 respectively.

[0150] In this way, since the processing technology of the waist-shaped hole is relatively simple, it can be facilitated to process.

[0151] 1 , the connection hole 111 may extend along directions A1 and A2 to form a waist-shaped hole structure. The inner sidewall of the connection hole 111 located on the A5 side and the inner sidewall located on the A6 side may form a first plane 1111 and a second plane 1112 respectively.

[0152] Referring to Figures 1, 2, and 4, a slide rail assembly 100 of the present application may include a locking spring 10, a slide rail 30, and a connector 31. The locking spring 10 may be the locking spring 10 of any of the aforementioned embodiments. The slide rail 30 may include a first slideway 40. The first slideway 40 may be provided with a connector 31. The connector 31 may be provided with a connecting hole 111. The connector 31 may abut against the teeth 1121 of the first tooth portion 112.

[0153] The above-mentioned slide rail assembly 100, by setting the first tooth portion 112 in the connecting hole 111, the connecting member 31 can interact with the teeth 1121 of the first tooth portion 112 during assembly, thereby improving the limiting effect of the connecting member 111 on the locking spring piece 10, making it less likely for the locking spring piece 10 to move and rotate, and can improve the safety and stability of the locking spring piece 10 when it moves relative to the slide rail 30.

[0154] 1 , the slide rail 30 may be provided with a fixing hole 45 . The connecting member 31 may penetrate the fixing hole 45 and the connecting hole 111 , so that the locking spring 10 is limitedly connected to the slide rail 30 .

[0155] 1 , the extending length of the connecting hole 111 along the length direction of the locking elastic piece 10 may be greater than the extending length of the fixing hole 45 along the length direction of the locking elastic piece 10 .

[0156] In this way, the connecting hole 111 can absorb the tolerance of the locking spring 10 along the moving direction during assembly.

[0157] Referring to FIG. 1 , the slide rail assembly 100 may include a snap-on portion 14 and an operating handle 20. The snap-on portion 14 may be formed at one end of the locking spring 10. The snap-on portion 14 may include a paddle 144. The operating handle 20 may include a handle end 21 and a notch 23. The operating handle 20 may be connected to the locking spring 10 by passing through the handle end 21. The snap-on portion 14 may be configured to elastically abut the notch 23 of the operating handle 20 via the paddle 144, thereby limiting the movement of the handle end 21 in the direction through which the locking spring 10 is passed.

[0158] In this way, the position deviation of the operating handle 20 along the insertion direction can be reduced.

[0159] 1 , the snap-on portion 14 may include an arcuate arm 141, a first straight arm 142, and a second straight arm 143. The arcuate arm 141 may be bent and extended from the locking spring 10. The arcuate arm 141, the first straight arm 142, the second straight arm 143, and the paddle element 144 may be sequentially connected to form a bent structure 140.

[0160] Referring to Figure 2, the first straight arm 142, the second straight arm 143, and the paddle member 144 can be located in the same plane. The locking spring 10 may include a fixing portion 11. The fixing portion 11 may be provided with a connecting hole 111. The arc-shaped arm 141 may be connected to the fixing portion 11. The locking spring 10 may be configured such that the angle formed by the first plane 1111 and the second plane 1112 ranges from 10° to 30°. The first plane 1111 may be the plane where the first straight arm 142, the second straight arm 143, and the paddle member 144 are located. The second plane 1112 may be the plane where the fixing portion 11 is located.

[0161] This helps to ensure the snap-fastening fixing effect of the snap-fastening portion 14 .

[0162] Referring to Figures 1 and 3, the slide rail assembly 100 may include a first bent portion 12. The first bent portion 12 may be provided with a first opening 122. The first opening 122 may be used to allow the locking spring 10 of the operating handle 20 to pass through. The operating handle 20 may include an end transition section. The surface shape of the sidewall of the first opening 122 may match the surface shape of the end transition section.

[0163] In this way, the contact area between the operating handle 20 and the locking elastic piece 10 can be increased, thereby improving the stability of the operating handle 20 and the locking elastic piece 10 during transmission.

[0164] Please refer to Figures 1, 2 and 5. The locking spring 10 may include a locking portion 13 and a second bending portion 15. The locking portion 13 may extend in a direction away from the connecting hole 111. The locking portion 13 may include a second tooth portion 131. The second tooth portion 131 may include at least one tooth 1121. The tooth 1121 of the second tooth portion 131 may be located at an end of the locking portion 13 away from the connecting hole 111. The second bending portion 15 may extend from an end of the locking portion 13 away from the connecting hole 111. At least a portion of the second bending portion 15 may pass through the first slide 40. The second bending portion 15 may be configured so that the portion of the second bending portion 15 passing through the first slide 40 can be driven by a force to drive the second tooth portion 131 to move around the connecting hole 111.

[0165] In this way, the locking and unlocking effects of the slide rail 30 can be easily achieved.

[0166] Referring to Figures 1 to 5, the slide rail assembly 100 may include a silencer 16, an elastic limiter 46, and an operating handle 20. The silencer 16 may be disposed on the locking spring 10. The elastic limiter 46 may be disposed on the first slideway 40. The operating handle 20 may include a handle end 21. The operating handle 20 may be connected to the locking spring 10 through the handle end 21. The silencer 16 and the elastic limiter 46 may be configured to cooperatively abut the handle end 21 to limit the movement of the operating handle 20 around the direction through which the locking spring 10 is penetrated.

[0167] In this way, the positional deviation of the operating handle 20 around the insertion direction can be reduced.

[0168] 5 and 6 , the slide rail 30 may include a second slide 50. The first slide 40 and the second slide 50 may be arranged in parallel. The first slide 40 may be provided with a tooth window 42. The second slide 50 may be provided with a tooth groove 51. The slide rail 30 may have an unlocked state and a locked state. In the locked state, the second tooth portion 131 of the locking spring 10 may penetrate the tooth window 42 and the tooth groove 51 to lock the first slide 40 and the second slide 50. In the unlocked state, the second tooth portion 131 may penetrate the tooth groove 51 to allow the first slide 40 to move relative to the second slide 50.

[0169] In this way, the locking and unlocking effects of the slide rail 30 can be easily achieved.

[0170] 7 , a seat 200 of the present application may include a seat body 210 and a slide rail assembly 100 according to any one of the above embodiments. The seat body 210 may be fixedly connected to the first slide rail 40 .

[0171] Specifically, the slide rail assembly 100 of the present application can be applied to a seat 200. The first slide rail 40 can be fixedly connected to the seat body 210, and the second slide rail 50 can be fixedly connected to the seat mounting base (not shown). The slide rail 30 can be in a locked state to fix the seat body 210 relative to the seat mounting base, thereby securing the seat body 210. The slide rail 30 can be in an unlocked state to allow the seat body 210 to move relative to the seat mounting base, thereby adjusting the seat body 210.

[0172] The above-mentioned seat 200, by setting the first tooth portion 112 in the connecting hole 111, the connecting member 31 can interact with the teeth 1121 of the first tooth portion 112 during assembly, thereby improving the limiting effect of the connecting member 111 on the locking spring plate 10, making it less likely for the locking spring plate 10 to move and rotate, and can improve the safety and stability of the locking spring plate 10 when it moves relative to the slide rail 30.

[0173] 8 and 9 , a vehicle 300 according to an embodiment of the present application may include the seat 200 according to the above embodiment, or may include the slide rail assembly 100 according to the above embodiment.

[0174] The vehicle 300 may include a vehicle or an airplane. By providing the vehicle 300 with a seat 200 having the slide rail assembly 100 of the present application, the slide rail 30 can be switched to a locked state when the seat 200 needs to be fixed, and can be switched to a locked state when the seat 200 needs to be adjusted. Due to the interaction between the first tooth portion 112 and the connector 31 provided on the side wall of the connecting hole 111, after the slide rail assembly 100 is assembled, the connector 31 can be deformed by force to fill the gap between the teeth 1121 of the first tooth portion 112, thereby absorbing external forces and preventing the locking spring 10 from being affected by external forces and affecting the stability of the seat 200.

[0175] The above-mentioned vehicle 300, by setting the first tooth portion 112 in the connecting hole 111, the connecting member 31 can interact with the teeth 1121 of the first tooth portion 112 during assembly, thereby improving the limiting effect of the connecting member 111 on the locking spring plate 10, making it less likely for the locking spring plate 10 to move and rotate, and can improve the safety and stability of the locking spring plate 10 when it moves relative to the slide rail 30.

[0176] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.
