[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.

[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.

Detailed Implementation

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] refer to Figure 1 , Figure 2 and Figure 3 This 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 achieving position adjustment 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.

[0042] A first guide surface 140 is connected to one side of the first locking groove 120, and a second guide surface 150 is connected to one side of the second locking groove 130. 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 component 200 on the slide rail 100.

[0043] 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.

[0044] In the extending direction of the slide rail 110, the first guide surface 140 slopes downwards, and the second guide surface 150 slopes upwards. When the sliding assembly 200 moves from the first end 111 to the second end 112, the first guide surface 140 guides the first locking member 210 to descend, and the second guide surface 150 guides the second locking member 220 to rise. When the sliding assembly 200 moves from the second end 112 to the first end 111, the first guide surface 140 guides the first locking member 210 to rise, and the second guide surface 150 guides the second locking member 220 to descend. Because the slope directions of the first guide surface 140 and the second guide surface 150 are opposite, when the sliding assembly 200 is unlocked and slides on the slide rail 100, the first locking member 210 and the second locking member 220 can produce opposite lifting and lowering movements. When the sliding assembly 200 moves bidirectionally under external force, one locking member is always in an actively locked state, forming bidirectional anti-disengagement protection.

[0045] 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.

[0046] In this embodiment, the slide 110 extends along the first direction X, and the first locking groove 120 and the second locking groove 130 are respectively disposed on two opposite groove walls of the slide 110 along the second direction Y. The lifting direction of the first locking member 210 and the second locking member 220 is the third direction Z, and the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. Through the orthogonal layout of the first direction X (the extension direction of the slide 110), the second direction Y (the distribution direction of the first locking groove 120 and the second locking groove 130), and the third direction Z (the movement direction of the first locking member 210 and the second locking member 220), functional integration within a cubic space is achieved. Compared with the traditional planar layout scheme, the space utilization is improved, and the locking stability of the sliding component 200 is good.

[0047] 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 third guide surface 211 is inclined from top to bottom, and the fourth guide surface 221 is inclined from bottom to top. That is, the first locking member 210 and the first guide surface 140 are in a beveled or arc-shaped fit, and the second locking member 220 and the second guide surface 150 are in a beveled or arc-shaped fit. Moreover, the inclination directions of the third guide surface 211 and the fourth guide surface 221 are opposite, forming a reverse wedge effect when the sliding assembly 200 moves, thereby improving the self-locking stability of the sliding assembly 200.

[0048] In one embodiment, multiple first locking grooves 120 are provided, and the multiple first locking grooves 120 are provided on one side of the groove wall of the slide groove 110 in the second direction Y. The multiple first locking grooves 120 are spaced apart in the first direction X. A first guide surface 140 is provided between any two adjacent first locking grooves 120. Multiple second locking grooves 130 are provided, and the multiple second locking grooves 130 are provided on the other side of the groove wall of the slide groove 110 in the second direction Y. The multiple second locking grooves 130 are spaced apart in the first direction X. A second guide surface 150 is provided between any two adjacent second locking grooves 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 providing multiple first locking grooves 120 and multiple second locking grooves 130 within the stroke 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, so as to reduce the displacement of the sliding assembly 200 continuing to slide, and so that the sliding assembly 200 can be locked in time.

[0049] 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 makes the force on the first locking member 210 and the second locking member 220 more even during lifting and lowering, 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 component 200.

[0050] 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.

[0051] refer to Figure 4 , Figure 6 and Figure 7 The sliding assembly 200 also includes a mounting base 230, a first pressure rod 240, and a second pressure rod 250. Both the first pressure rod 240 and the second pressure rod 250 are movably mounted on the mounting base 230. One end of the first pressure rod 240 is connected to the first locking member 210, and one end of the second pressure rod 250 is connected to the second locking member 220. When the first pressure rod 240 and the second pressure rod 250 are pressed along the third direction Z, the first locking member 210 can disengage from the first locking groove 120, and the second locking member 220 can disengage from the second locking groove 130, thus unlocking the sliding assembly 200. Specifically, by pressing the first pressure rod 240 and the second pressure rod 250, both the first locking member 210 and the second locking member 220 can be displaced downwards. 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 first pressure lever 240 and the second pressure lever 250 can be connected to a control system to achieve remote unlocking, suitable for scenarios involving automated locking or unlocking. By controlling the first locking element 210 to unlock via the first pressure lever 240 and the second locking element 220 to unlock via the second pressure lever 250, a safety mechanism can be added, such as requiring specific tools or procedures to unlock, to prevent accidental operation.

[0052] The sliding assembly 200 further includes a first elastic element 260 and a second elastic element 270. One end of the first elastic element 260 is connected to the first locking element 210, and the other end is connected to the mounting base 230. One end of the second elastic element 270 is connected to the second locking element 220, and the other end is connected to the mounting base 230. The elastic force of the first elastic element 260 allows the first locking element 210 to automatically return to the locked position after unlocking, and the elastic force of the second elastic element 270 allows the second locking element 220 to automatically return to the locked position after unlocking, improving the convenience and efficiency of operation.

[0053] Optionally, both the first elastic element 260 and the second elastic element 270 are tension springs. When the first pressure rod 240 and the second pressure rod 250 are pressed down, the elastic force exerted on the first locking member 210 by the first elastic element 260 gradually increases, and the elastic force exerted on the second locking member 220 by the second elastic element 270 gradually increases. The first elastic element 260 and the second elastic element 270 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.

[0054] In one embodiment, multiple first elastic elements 260 and multiple second elastic elements 270 are provided. In the first direction X, two first elastic elements 260 are respectively connected to both ends of the first locking element 210, and two second elastic elements 270 are respectively connected to both ends of the second locking element 220. The first elastic elements 260 at both ends ensure that the first locking element 210 is subjected to uniform force, and the second elastic elements 270 at both ends ensure that the second locking element 220 is subjected to uniform force, avoiding local stress concentration and improving locking reliability. Furthermore, the two first elastic elements 260 and the two second elastic elements 270 arranged at both ends can resist the deflection of the first locking element 210 and the second locking element 220 during movement, maintaining the correct alignment of the first locking element 210 with the first locking groove 120 and the second locking element 220 with the second locking groove 130.

[0055] The working principle of the locking mechanism provided in this application embodiment, when applied to a vehicle seat, is as follows:

[0056] When the vehicle is running smoothly and safely, and the seat is manually unlocked and adjusted, pressing down on the first lever 240 and the second lever 250, in conjunction with the action of the first elastic element 260 and the second elastic element 270, causes the first locking element 210 and the second locking element 220 to move downwards. The first locking element 210 disengages from the first locking groove 120, and the second locking element 220 disengages from the second locking groove 130. At this time, the sliding assembly 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 body moves to a comfortable position, the seat lock adjustment can be activated. At this time, the first pressure rod 240 and the second pressure rod 250 lose their downward pressing force. The first pressure rod 240 moves upward under the reaction force of the first elastic element 260, thereby driving the first locking element 210 into the first locking groove 120. The second pressure rod 250 moves upward under the reaction force of the second elastic element 270, thereby driving the second locking element 220 into the second locking groove 130, forming an alternating engagement. The sliding component 200 is in the locked state, the seat body is locked, and movement stops.

[0057] However, after the first locking member 210 moves downwards and disengages from the first locking groove 120, and the second locking member 220 moves downwards and disengages from the second locking groove 130, and the sliding assembly 200 is unlocked, if a collision or other situation suddenly 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 first pressure rod 240 and the first elastic member 260, and the combined action of the second pressure rod 250 and the second elastic member 270, causes both the first locking member 210 and the second locking member 220 to have an upward movement tendency. In the event of a sudden collision at the rear of the vehicle, the seat body and its accessories will move backwards relative to the vehicle body. The first locking member 210 moves backwards 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 cannot continue to rise. The second locking member 220 also enters the next second locking groove 130, and the sliding assembly 200 is locked. Conversely, in the event of a sudden collision at the front of the vehicle, 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 continue to rise. 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.
