Description

Technical Field

[0001] This application relates to the field of seating technology, specifically to a locking mechanism and a seat. Background Technology

[0002] With the development of the automotive industry, customers have increasingly higher requirements for vehicle safety and comfort. Among these, vehicle seats have a crucial impact on vehicle safety and comfort. A vehicle seat consists of a seat body and a sliding rail system. The seat body is mounted on the vehicle chassis via the sliding rail system. The sliding rail system includes a lower sliding rail fixed to the chassis and an upper sliding rail fixed to the seat body. The upper and lower sliding rails maintain a sliding fit, and the upper sliding rail can be fixed to a predetermined position after moving a certain distance along the lower sliding rail.

[0003] In related technologies, the locking device between the upper and lower slide rails adopts an electrically controlled mechanical locking method. In special circumstances such as sudden vehicle collisions during electric unlocking, due to the instantaneous acceleration value generated in the vehicle's forward and backward directions, the locking device may have insufficient movement displacement in the locking direction, resulting in insufficient locking force, causing the seat to slide, which may affect the stability of the seat and the safety of passengers. Utility Model Content

[0023] In one embodiment, the sliding assembly further includes a first elastic element and a second elastic element, and the mounting base is provided with a first connecting portion and a second connecting portion.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] 1. In this application, by setting a groove on the slide rail, the sliding component can slide on the slide rail.

Detailed Implementation

[0040] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0041] As the automotive industry develops, customers have increasingly higher demands for vehicle safety and comfort. Among these, the locking mechanism is a key component that ensures the stability of the vehicle's seats during driving, and its impact on vehicle safety and comfort is extremely important.

[0042] Existing long-rail locking mechanisms typically employ electrically controlled mechanical locking, with an alternating interlocking surface design. When the locking mechanism is unlocked and the seat's fore-and-aft position is electrically adjusted, in the event of a sudden collision or other emergency, the instantaneous acceleration in the vehicle's forward and backward directions may cause insufficient movement in the locking direction, resulting in inadequate locking force and seat slippage. This poses a safety hazard, affecting seat stability and passenger safety.

[0043] This application provides a seat, including a seat body (not shown) and a locking mechanism. The locking mechanism can unlock the seat body and adjust the seat body's fore-and-aft position. The locking mechanism can also lock the seat body after the seat body is adjusted or when the seat body suddenly shifts, thereby improving the stability of the seat body and protecting the safety of passengers.

[0044] refer to Figure 1 , Figure 2 and Figure 3This application provides a locking mechanism, including a slide rail 100 and a sliding component 200. The slide rail 100 is mounted on the vehicle frame, and the sliding component 200 is disposed on the seat body, and the sliding component 200 can slide on the slide rail 100. The slide rail 100 includes a groove 110, a first locking groove 120, and a second locking groove 130. By providing the groove 110 on the slide rail 100, the sliding component 200 can slide on the slide rail 100, enabling the seat body to move relative to the slide rail 100, thereby adjusting the fore-and-aft position of the seat body. The slide groove 110 includes a first end 111 and a second end 112 in the extension direction of the slide groove 110. The first locking groove 120 and the second locking groove 130 are respectively disposed on two opposite groove walls of the slide groove 110. The sliding assembly 200 is movably disposed in the slide groove 110. The sliding assembly 200 includes a first locking member 210 and a second locking member 220. Through the cooperation of the first locking member 210 with the first locking groove 120 and the cooperation of the second locking member 220 with the second locking groove 130, the bidirectional locking of the sliding assembly 200 on the slide rail 100 is realized.

[0045] In the extending direction of the slide groove 110, a first guide surface 140 is connected to the side of the first locking groove 120 near the first end 111, and a second guide surface 150 is connected to the side of the second locking groove 130 near the second end 112. The first guide surface 140 and the second guide surface 150 are parallel. By connecting the first guide surface 140 to the side of the first locking groove 120 near the first end 111 and the second guide surface 150 to the side of the second locking groove 130 near the second end 112, and by setting the first guide surface 140 and the second guide surface 150 parallel to each other, when the locking mechanism is unlocked, the first guide surface 140 and the second guide surface 150 not only guide the locking member to slide into the locking groove, but also ensure the smoothness of the movement of the sliding assembly 200 on the slide rail 100.

[0046] When the sliding assembly 200 moves from the first end 111 to the second end 112, the first locking member 210 slides into the first locking groove 120 along the first guide surface 140, and the sliding assembly 200 is locked. When the sliding assembly 200 moves from the second end 112 to the first end 111, the second locking member 220 slides into the second locking groove 130 along the second guide surface 150, and the sliding assembly 200 is locked. Specifically, when the locking mechanism is applied to a vehicle seat, regardless of whether the vehicle experiences a front-end or rear-end collision, the locking mechanism can ensure the locking of the sliding assembly 200 through the first locking member 210 or the second locking member 220, thereby keeping the seat body in a locked state to stop movement, improving the stability of the seat body, and protecting the safety of passengers.

[0047] When the sliding component 200 moves from the first end 111 to the second end 112, the first guide surface 140 drives the first locking member 210 away from the second locking member 220, and the second guide surface 150 drives the second locking member 220 towards the first locking member 210. When the sliding component 200 moves from the second end 112 to the first end 111, the first guide surface 140 drives the first locking member 210 towards the second locking member 220, and the second guide surface 150 drives the second locking member 220 away from the first locking member 210. Through the arrangement of the first guide surface 140 and the second guide surface 150, when the sliding component 200 slides on the slide rail 100, the first locking member 210 and the second locking member 220 can move in opposite directions. Depending on the sliding direction of the sliding component 200, the first locking member 210 and the second locking member 220 can be locked or unlocked respectively, realizing a two-way locking function.

[0048] The first guide surface 140 can be an arc surface, a plane, or a combination of an arc surface and a plane, and the second guide surface 150 can be an arc surface, a plane, or a combination of an arc surface and a plane.

[0049] In this embodiment, the slide groove 110 extends along the first direction X. The slide groove 110 includes a first groove wall 113 and a second groove wall 114 opposite to each other in the second direction Y. The first direction X intersects the second direction Y. The first locking groove 120 and the first guide surface 140 are both disposed on the first groove wall 113, and the second locking groove 130 and the second guide surface 150 are both disposed on the second groove wall 114. By providing the first locking groove 120 and the second locking groove 130 on the first groove wall 113 and the second groove wall 114 respectively, the sliding component 200 can be locked when it moves along the first direction X.

[0050] In the first direction X, the distance between the first guide surface 140 and the first groove wall 113 gradually decreases from the first end 111 to the second end 112, while the distance between the second guide surface 150 and the second groove wall 114 gradually increases from the first end 111 to the second end 112. That is, in the first direction X, the distance between the first guide surface 140 and the first groove wall 113, and the distance between the second guide surface 150 and the second groove wall 114, change in opposite directions. This allows the first locking member 210 to gradually contact or separate from the first guide surface 140 during movement, and the second locking member 220 to gradually contact or separate from the second guide surface 150 during movement, thereby controlling the movement trajectories of the first locking member 210 and the second locking member 220.

[0051] refer to Figures 2-6The first locking member 210 has a third guide surface 211 that mates with the first guide surface 140, and the second locking member 220 has a fourth guide surface 221 that mates with the second guide surface 150. In the first direction X, the distance between the third guide surface 211 and the first groove wall 113 gradually decreases from the first end 111 to the second end 112, and the distance between the fourth guide surface 221 and the second groove wall 114 gradually increases from the first end 111 to the second end 112. That is, the first locking member 210 and the first guide surface 140 are in a beveled fit, the second locking member 220 and the second guide surface 150 are in a beveled fit, and the third guide surface 211 and the fourth guide surface 221 are also arranged in parallel, forming a reverse wedge effect when the sliding assembly 200 moves, thereby improving the self-locking stability of the sliding assembly 200.

[0052] In one embodiment, multiple first locking slots 120 are provided, each of which is disposed on a first slot wall 113. The multiple first locking slots 120 are spaced apart in the first direction X, and a first guide surface 140 is provided between any two adjacent first locking slots 120. Multiple second locking slots 130 are provided, each of which is disposed on a second slot wall 114. The multiple second locking slots 130 are spaced apart in the first direction X, and a second guide surface 150 is provided between any two adjacent second locking slots 130. Specifically, multiple first locking grooves 120 are disposed on the same groove wall of the slide groove 110, and multiple second locking grooves 130 are disposed on another groove wall of the slide groove 110. By disposing of multiple first locking grooves 120 and multiple second locking grooves 130 within the travel range of the slide groove 110, when the sliding assembly 200 needs to be locked during the sliding process, the first locking member 210 and the second locking member 220 can respectively enter the nearest first locking groove 120 and the second locking groove 130, thereby reducing the displacement of the sliding assembly 200 as it continues to slide, and enabling the sliding assembly 200 to be locked in a timely manner.

[0053] At least two first guide surfaces 140 are provided between the multiple first locking grooves 120, and the two first guide surfaces 140 are arranged in parallel. The multiple first guide surfaces 140 increase the stability of the first locking member 210 during movement, reduce skewness or wobbling, and improve locking accuracy. At least two second guide surfaces 150 are provided between the multiple second locking grooves 130, and the two second guide surfaces 150 are arranged in parallel. The multiple second guide surfaces 150 increase the stability of the second locking member 220 during movement, reduce skewness or wobbling, and improve locking accuracy. Furthermore, the parallel arrangement of the multiple first guide surfaces 140 and the multiple second guide surfaces 150 ensures that the first locking member 210 and the second locking member 220 are subjected to more even force during their movement, ensuring that the first locking member 210 and the second locking member 220 move along the same path, reducing jamming or impact, and improving the smoothness of the movement of the sliding assembly 200.

[0054] Optionally, the first locking member 210 includes a plurality of first locking blocks, each locking block having a third guide surface 211; the second locking member 220 includes a plurality of second locking blocks, each locking block having a fourth guide surface 221. Through the cooperation of the plurality of first locking blocks with the plurality of first locking grooves 120, and the cooperation of the plurality of second locking blocks with the plurality of second locking grooves 130, the locking stability of the sliding assembly 200 is further improved.

[0055] In this application, the sliding assembly 200 further includes a mounting base 230 and a pressing member 240. The first locking member 210 and the second locking member 220 are rotatably mounted on the mounting base 230. One end of the pressing member 240 is connected to the first locking member 210, and the other end is connected to the second locking member 220. When the pressing member 240 is pressed, the first locking member 210 rotates to disengage from the first locking groove 120, and the second locking member 220 rotates to disengage from the second locking groove 130, thus unlocking the sliding assembly 200. Specifically, by pressing the pressing member 240, the first locking member 210 and the second locking member 220 can be brought closer together, the first locking member 210 disengages from the first locking groove 120, and the second locking member 220 disengages from the second locking groove 130. At this time, the entire sliding assembly 200 can slide along the sliding groove 110. Furthermore, the pressing member 240 can be connected to a control system to achieve remote unlocking, suitable for scenarios requiring automated locking or unlocking. By controlling the first locking element 210 and the second locking element 220 to unlock via the pressing element 240, a security mechanism can be added, such as requiring specific tools or steps to unlock, to prevent accidental operation.

[0056] The mounting base 230 is provided with a first rotating shaft 231 and a second rotating shaft 232. A first locking member 210 is rotatably connected to the first rotating shaft 231, and a second locking member 220 is rotatably connected to the second rotating shaft 232. The first locking member 210 is provided with a first abutting part 212, and the second locking member 220 is provided with a second abutting part 222. The two ends of the pressing member 240 abut against the first abutting part 212 and the second abutting part 222, respectively. The pressing member 240 abuts against the first locking member 210 via the first abutting part 212 and against the second locking member 220 via the second abutting part 222. Pressing the pressing member 240 can drive the first locking member 210 to rotate around the first rotating shaft 231 and the second locking member 220 to rotate around the second rotating shaft 232, thereby causing the first locking members 210 to come closer to each other, the first locking member 210 to disengage from the first locking groove 120, and the second locking member 220 to disengage from the second locking groove 130, thereby unlocking the sliding component 200.

[0057] The sliding assembly 200 also includes a first elastic element 250 and a second elastic element 260. The mounting base 230 is provided with a first connecting portion 233 and a second connecting portion 234. The first connecting portion 233 and the first abutting portion 212 are spaced apart in the circumferential direction of the first rotating shaft 231. The second connecting portion 234 and the second abutting portion 222 are spaced apart in the circumferential direction of the second rotating shaft 232. One end of the first elastic element 250 is connected to the first connecting portion 233, and the other end of the first elastic element 250 is connected to the first abutting portion 212. One end of the second elastic element 260 is connected to the second connecting portion 234, and the other end of the second elastic element 260 is connected to the second abutting portion 222. The first elastic element 250 connects the first connecting portion 233 of the mounting base 230 and the first abutting portion 212 of the first locking element 210. The second elastic element 260 connects the second connecting portion 234 of the mounting base 230 and the second abutting portion 222 of the second locking element 220. The first connecting portion 233 and the first abutting portion 212 are spaced apart in the circumferential direction of the first rotating shaft 231, and the second connecting portion 234 and the second abutting portion 222 are spaced apart in the circumferential direction of the second rotating shaft 232. This causes the first elastic element 250 to generate torque when the first locking element 210 rotates, and the second elastic element 260 to generate torque when the second locking element 220 rotates, so as to drive the first locking element 210 and the second locking element 220 to reset or remain locked.

[0058] Optionally, both the first elastic element 250 and the second elastic element 260 are torsion springs. When the pressing member 240 is pressed down, the elastic force exerted on the first locking member 210 by the first elastic element 250 gradually increases, and the elastic force exerted on the second locking member 220 by the second elastic elements 260 and 270 gradually increases. The first elastic element 250 and the second elastic element 260 provide a continuous preload, ensuring tight contact between the first locking member 210 and the first locking groove 120, and between the second locking member 220 and the second locking groove 130, thereby improving locking reliability and preventing accidental unlocking due to vibration or impact.

[0059] The working principle of the locking mechanism provided in this application embodiment, when applied to a vehicle seat, is as follows:

[0060] When the vehicle is running smoothly and safely, and the seat adjustment is manually activated, pressing down on the pressing member 240, in conjunction with the first elastic member 250 and the second elastic member 260, causes the first locking member 210 and the second locking member 220 to move closer together. The first locking member 210 disengages from the first locking groove 120, and the second locking member 220 disengages from the second locking groove 130. At this time, the sliding component 200 is in the unlocked state, and the seat body can slide freely along the sliding groove 110; the moving motor drives the seat body... When the seat is moved to a comfortable position, the seat locking adjustment can be activated. At this time, the pressing member 240 is released. The pressing member 240 moves upward under the reaction force of the first elastic member 250 and the second elastic member 260, and the first locking member 210 and the second locking member 220 move away from each other. This causes the first locking member 210 to enter the first locking groove 120 and the second locking member 220 to enter the second locking groove 130, forming an alternating engagement. The sliding component 200 is in the locked state, the seat body is locked, and the movement stops.

[0061] However, when the first locking member 210 moves closer to the second locking member 220 and disengages from the first locking groove 120, and the second locking member 220 moves closer to the first locking member 210 and disengages from the second locking groove 130, after the sliding assembly 200 is unlocked, if a collision or other situation occurs while the seat body is adjusting its position, the vehicle ECU (electronic control unit) or collision sensor will send a signal to activate the locking adjustment. The combined action of the pressing member 240, the first elastic member 250, and the second elastic member 260 causes the first locking member 210 and the second locking member 220 to tend to move away from each other. In the event of a sudden rear-end collision, the seat body and its accessories will move backward relative to the vehicle body. The first locking member 210 moves backward along the first guide surface 140 until it is locked into the next first locking groove 120. After the first locking member 210 enters the first locking groove 120, it will be restricted by the first locking groove 120 and will not be able to move backward further. The second locking member 220 will also enter the next second locking groove 130, and the sliding assembly 200 will be locked. Conversely, in the event of a sudden frontal collision, the seat body and its accessories will move forward relative to the vehicle body. The second locking member 220 will move forward along the second guide surface 150 until it is engaged in the next second locking groove 130. After the second locking member 220 enters the second locking groove 130, it will be restricted by the second locking groove 130 and will not be able to move forward. The first locking member 210 will also enter the next first locking groove 120, forming an alternating engagement and locking, and the sliding component 200 will be locked.

[0062] Therefore, with the locking mechanism provided in this application, regardless of whether a front-end or rear-end collision occurs, the locking mechanism always has a first locking element 210 or a second locking element 220 to ensure normal locking. The locking mechanism of this application is designed to quickly and alternately engage and lock, keeping the seat body in a locked state, stopping its movement, and protecting the safety of the occupant.

[0063] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0064] Furthermore, the use of terms such as "first," "second," and "a" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0066] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.
