Description

Technical Field

[0001] This application relates to the field of vehicle interior technology, and in particular to a slide rail assembly, a slide rail assembly, and a vehicle. Background Technology

[0002] A slide rail assembly is a guide device that connects two components that can slide relative to each other. A slide rail assembly typically includes an outer slide rail, an inner slide rail, and a locking mechanism. The inner slide rail is slidably disposed in the outer slide rail. The inner and outer slide rails are respectively connected and arranged on the two components. The locking mechanism can lock the relative position of the inner and outer slide rails.

[0003] Sliding rail assemblies are widely used. For example, vehicle seats are usually connected to the vehicle floor via sliding rail assemblies. However, when such sliding rail assemblies are used, in the event of a frontal collision, the sliding rail assemblies are locked, and the impact force transmitted from the seat to the occupant due to inertia is relatively large, which is not conducive to improving safety. Utility Model Content

[0004] In view of this, this application aims to provide a slide rail assembly to improve safety in use.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A slide rail assembly includes an outer slide rail, an inner slide rail slidable relative to the outer slide rail, and a damping mechanism disposed between the outer slide rail and the inner slide rail. The damping mechanism includes a first damping part disposed on one of the outer slide rail and the inner slide rail, and a second damping part disposed on the other of the outer slide rail and the inner slide rail; a locking mechanism capable of locking the first damping part and the second damping part together is provided between them. The locking mechanism releases the first damping part and the second damping part, allowing the inner slide rail to slide relative to the outer slide rail, and the first damping part and the second damping part to rub against each other, thereby applying damping to the sliding of the inner slide rail relative to the outer slide rail.

[0006] Furthermore, a cavity is provided between the outer slide rail and the inner slide rail, the length direction of the cavity extends along the sliding direction of the inner slide rail, and the damping mechanism is disposed in the cavity.

[0007] Furthermore, the first damping part is provided with a damping hole, and the second damping part includes a damping rod passing through the damping hole, the damping rod extending along the sliding direction of the inner slide rail.

[0008] Furthermore, the outer slide rail is provided with a first support frame and a second support frame, which are arranged at intervals along the sliding direction of the inner slide rail, and the two ends of the damping rod are respectively provided on the first support frame and the second support frame.

[0009] Furthermore, the damping rod is a threaded rod.

[0010] Furthermore, the first damping part includes a first damping plate and a second damping plate having the damping hole, and a connecting plate connecting the first damping plate and the second damping plate together; The first damping plate and the second damping plate are respectively connected to the inner slide rail, and the first damping plate and the second damping plate are arranged at intervals along the sliding direction of the inner slide rail.

[0011] Furthermore, the first damping part is detachably connected to the inner slide rail, or the second damping part is detachably connected to the inner slide rail.

[0012] Furthermore, the locking mechanism includes a locking unit disposed on one of the first damping part and the second damping part, and a locking hole disposed on the other of the first damping part and the second damping part; The locking unit includes a housing, a sliding part slidably disposed within the housing, and a locking pin with one end connected to the sliding part and the other end extending out of the housing; The locking pin is inserted into the locking hole, which can lock the first damping part and the second damping part together.

[0013] Furthermore, the housing contains gunpowder and an igniter, the igniter being used to connect to the seat controller; Received from the control information of the seat controller, the igniter can ignite the gunpowder, thereby causing the sliding part to slide relative to the housing. The sliding part can drive the locking pin to disengage from the locking hole, thereby releasing the locking of the first damping part and the second damping part.

[0014] Compared with related technologies, this application has the following advantages: (1) The slide rail assembly described in this application, by setting an outer slide rail and an inner slide rail that can slide relative to each other, and setting a damping mechanism between the outer slide rail and the inner slide rail, can make the outer slide rail slide relative to the inner slide rail damped. At the same time, in conjunction with the locking mechanism, the inner slide rail and the outer slide rail can be locked in the normal state. When the locking mechanism is unlocked, when the inner slide rail moves relative to the outer slide rail, the first damping part and the second damping part will rub and absorb energy, which plays a buffering role and is conducive to improving the safety of the slide rail assembly. When used in a vehicle, the outer slide rail is connected to the vehicle and the inner slide rail is connected to the seat. When the vehicle decelerates or stops in a frontal collision accident, the seat and the occupants on the seat will have forward kinetic energy under the action of inertia. At this time, when the locking mechanism is unlocked, the first damping part and the second damping part will slide relative to each other and generate friction to consume kinetic energy, which plays a buffering role and reduces the impact on the occupants on the seat, which is conducive to improving the safety of the vehicle.

[0015] (2) A cavity is set between the outer slide rail and the inner slide rail, so that the damping mechanism can be arranged in the cavity without occupying external space, making the overall structure of the slide rail assembly more compact. At the same time, the outer slide rail and the inner slide rail isolate the damping mechanism from the external environment, which can block some dust, debris and other objects from entering the damping mechanism, and protect the damping mechanism from external impact, thus extending its service life.

[0016] (3) The damping rod and damping hole form a form in which the damping rod and the wall of the damping hole can rub against each other when sliding occurs between the first damping part and the second damping part, so as to absorb energy. At the same time, the damping rod extends along the sliding direction of the inner slide rail and forms a linear contact with the damping hole. The friction contact point is continuous during the sliding process, which is conducive to reducing the fluctuation of the damping force and improving the stability of the damping force output.

[0017] (4) The first support frame and the second support frame are arranged at intervals along the sliding direction and fix the two ends of the damping rod respectively, which can form two-point support for the damping rod and the support effect is stable. At the same time, the design of the first support frame and the second support frame facilitates the disassembly and replacement of the damping rod. The damping rod is set as a threaded rod, which has a high friction effect, making the damping force of the damping mechanism higher and the buffering effect better.

[0018] (5) The first damping plate and the second damping plate are provided, and damping holes are provided respectively. This enables the first damping part and the damping rod to form two friction contact points. Compared with the single damping hole structure, the friction contact area is larger, which can better buffer the sliding impact. At the same time, the connecting plate connects the first damping plate and the second damping plate into a frame structure, which enhances the overall rigidity of the first damping part and reduces the risk of deformation or damage to the first damping part. The symmetrical arrangement of the first damping plate and the second damping plate can balance the lateral force generated during the sliding process and ensure the smooth movement of the inner slide rail.

[0019] (6) The first damping part is detachably connected to the inner slide rail, or the second damping part is detachably connected to the inner slide rail, so that the first damping part or the second damping part can be easily separated from the inner slide rail, so that the inner slide rail can be removed and the first damping part or the second damping part inside can be exposed for replacement.

[0020] (7) The locking pin is inserted into the locking hole and rigid locking is achieved through mechanical structure. The structure is simple, the locking and unlocking actions are clear, and it is not easy to jam or mis-lock. In addition, the housing of the locking unit and the sliding part have high matching accuracy, and the movement trajectory of the locking pin is accurate, which helps to improve the reliability of the locking mechanism.

[0021] (8) The high-pressure gas generated by the combustion of gunpowder can quickly push the sliding part and drive the locking pin out of the locking hole. The unlocking response time is short. Compared with the traditional mechanical unlocking mechanism, it can unlock the inner slide rail more quickly, so that the damping mechanism can start to absorb the collision energy earlier. The igniter is connected to the seat controller and can receive signals from the vehicle collision sensor, seat belt pretensioner and other components to realize the automatic triggering of unlocking. In addition, the seat controller can adjust the unlocking timing according to different scenarios to improve the accuracy of control.

[0022] Another object of this application is to provide a slide rail assembly comprising two sets of slide rail components arranged side by side, and a connector for connecting the inner slide rails of the two sets of slide rail components together, wherein the slide rail components adopt the slide rail components described above.

[0023] The slide rail assembly described in this application, by arranging two sets of slide rail components side by side, can distribute the weight and load of the seat, resulting in strong load-bearing capacity. Secondly, the connector links the two sets of inner slide rails into one, enhancing the rigidity of the overall structure and ensuring that the two sets of inner slide rails move synchronously during sliding, reducing seat tilting caused by jamming or misalignment of a single set of slide rails, and improving the smoothness and precision of seat adjustment. At the same time, when the vehicle decelerates or stops in a frontal collision, the first damping part and the second damping part will slide relative to each other, generating friction to dissipate collision energy, playing a buffering role for the seat and occupants, reducing the impact on the occupants in the seat, and thus improving vehicle safety.

[0024] Another object of this application is to provide a vehicle in which the seats are mounted to the vehicle body via the aforementioned slide rail assembly.

[0025] The vehicle described in this application has its seats mounted on the vehicle body via the aforementioned sliding rail assembly. In the event of a frontal collision, the first damping part and the second damping part will slide relative to each other, generating friction to dissipate the collision energy, thus buffering the seats and occupants, reducing the impact on the occupants, and improving vehicle safety. At the same time, it works in conjunction with other vehicle safety systems, such as seat belt pretensioners and airbags, to improve the overall safety performance of the vehicle.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides a slide rail assembly to improve vehicle safety.

[0034] A slide rail assembly is a guide device that connects two components that can slide relative to each other. A slide rail assembly typically includes an outer slide rail, an inner slide rail, and a locking mechanism. The inner slide rail is slidably disposed in the outer slide rail. The inner and outer slide rails are respectively connected and arranged on the two components. The locking mechanism can lock the relative position of the inner and outer slide rails.

[0035] Slide rail assemblies are widely used in industrial slides, lifts, vehicles, and other fields. For example, vehicle seats are typically connected to the vehicle floor via slide rails, enabling the seat to slide forward and backward and lock in position.

[0036] However, in some vehicles, to meet social needs, the front two rows of seats can be rotated so that the front two rows and the rear two rows of seats are arranged face-to-face, allowing occupants in both rows to communicate directly. With this seating arrangement, in the event of a frontal collision, the sliding rails of the rear-facing seats are locked. Due to inertia, the occupants in these seats will directly collide with the seats behind them, rendering the sliding rails ineffective in providing cushioning and compromising safety.

[0037] In view of this, in order to overcome the shortcomings of the related technology, the slide rail assembly of this embodiment combines... Figures 1 to 3 In terms of content and overall design, it includes an outer slide rail 1, an inner slide rail 2 that can slide relative to the outer slide rail 1, and a damping mechanism 3 located between the outer slide rail 1 and the inner slide rail 2.

[0038] The damping mechanism 3 includes a first damping part 301 disposed on one of the outer slide rail 1 and the inner slide rail 2, and a second damping part 302 disposed on the other of the outer slide rail 1 and the inner slide rail 2. A locking mechanism 4 is provided between the first damping part 301 and the second damping part 302 to lock them together. The locking mechanism 4 releases the first damping part 301 and the second damping part 302, allowing the inner slide rail 2 to slide relative to the outer slide rail 1, and the first damping part 301 and the second damping part 302 can rub against each other, thereby applying damping to the sliding of the inner slide rail 2 relative to the outer slide rail 1.

[0039] Therefore, by setting an outer slide rail 1 and an inner slide rail 2 that can slide relative to each other, and by setting a damping mechanism 3 between the outer slide rail 1 and the inner slide rail 2, damping is provided when the outer slide rail 1 slides relative to the inner slide rail 2. Simultaneously, in conjunction with the locking mechanism 4, the inner slide rail 2 and the outer slide rail 1 can be locked in normal conditions. After the locking mechanism 4 is unlocked, the inner slide rail 2 can slide along the extension direction of the outer slide rail 1. Correspondingly, relative friction is generated between the first damping part 301 and the second damping part 302, and energy is consumed through frictional work, buffering the relative sliding between the inner slide rail 2 and the outer slide rail 1. This allows the damping mechanism 3 to absorb energy. After the energy is exhausted by the friction between the first damping part 301 and the second damping part 302, the first damping part 301 stops sliding relative to the second damping part 302, and the inner slide rail 2 can stop on the outer slide rail 1.

[0040] When the slide rail assembly is used in a vehicle, the outer slide rail 1 is connected to the vehicle and the inner slide rail 2 is connected to the seat. When the vehicle decelerates or stops in the event of a frontal collision, the seat and the occupants on it will have forward kinetic energy due to inertia, which may lead to a collision. At this time, the locking mechanism 4 is unlocked, and the first damping part 301 and the second damping part 302 will slide relative to each other to generate friction and consume kinetic energy, which plays a buffering role and reduces the impact on the occupants on the seat, thus improving the safety of the vehicle.

[0041] Based on the above overview, specifically, when the slide rail assembly of this application is used in a vehicle, the outer slide rail 1 needs to be connected to the vehicle floor or body, and the inner slide rail 2 needs to be connected to the seat. The sliding direction of the inner slide rail 2 relative to the outer slide rail 1 is the front-to-back direction of the vehicle. In the event of a collision, the occupants and their seats will have an inertia that moves forward, which is consistent with the sliding direction of the inner slide rail 2 relative to the outer slide rail 1. After the locking mechanism 4 is unlocked, the inner slide rail 2 will slide relative to the outer slide rail 1 due to the pushing force applied by the seat above it. When the inner slide rail 2 slides relative to the outer slide rail 1, the first damping part 301 and the second damping part 302 will also slide relative to each other, generating friction and consuming collision energy. This allows the damping mechanism 3 to absorb energy, thereby enabling the slide rail assembly to cushion the seat.

[0042] In specific implementation, in the direction of vehicle travel, the outer slide rail 1 should leave a sufficient sliding distance in front of the inner slide rail 2 so that the first damping part 301 and the second damping part 302 can fully absorb energy through friction. The first damping part 301 and the second damping part 302 need to always maintain contact, and there needs to be a sufficient sliding friction distance between them.

[0043] It is understood that the slide rail assembly of this application can be used not only between the seat and body of a vehicle, but also in other scenarios, such as anti-collision design of industrial slides, anti-collision design of elevators, etc. In cases where there is relative sliding between two parts and there is a need for anti-collision buffering, the slide rail assembly of this application can be considered for adaptation and use.

[0044] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, a cavity a is provided between the outer slide rail 1 and the inner slide rail 2, the length direction of the cavity a extends along the sliding direction of the inner slide rail 2, and the damping mechanism 3 is provided in the cavity a.

[0045] With this arrangement, cavity a is set between outer slide rail 1 and inner slide rail 2, and damping mechanism 3 can be arranged in cavity a without occupying external space. This makes the overall structure of the slide rail assembly more compact, and damping mechanism 3 is not exposed, resulting in higher appearance quality.

[0046] Meanwhile, the outer slide rail 1 and the inner slide rail 2 isolate the damping mechanism 3 from the external environment, preventing some dust and debris from entering the damping mechanism 3 and protecting it from external impacts, thus extending its service life. Alternatively, the locking mechanism 4 can be placed inside the cavity a, so that the outer slide rail 1 and the inner slide rail 2 can cover the outside of the locking mechanism 4 to protect it.

[0047] With the damping mechanism 3 located inside the cavity a, in some exemplary embodiments, the first damping part 301 is provided with a damping hole 3011, and the second damping part 302 includes a damping rod 3021 passing through the damping hole 3011, the damping rod 3021 extending along the sliding direction of the inner slide rail 2.

[0048] In this way, with the damping rod 3021 and the damping hole 3011 in a form that allows for mutual friction between the damping rod 3021 and the hole wall of the damping hole 3011 when sliding occurs between the first damping part 301 and the second damping part 302, energy absorption is achieved. At the same time, the damping rod 3021 extends along the sliding direction of the inner slide rail 2 and forms a linear contact with the damping hole 3011. The friction contact points are continuous during the sliding process, which helps to reduce the fluctuation of the damping force and improve the stability of the damping force output.

[0049] In specific implementation, for example, the first damping part 301 can be set on the inner slide rail 2, and the damping rod 3021 can be set on the outer slide rail 1 along the extension direction of the outer slide rail 1. The damping rod 3021 needs to leave enough distance in front of the first damping part 301 so that the first damping part 301 can eventually stop on the damping rod 3021 under the action of friction, and cannot detach from the damping rod 3021 or collide with other components.

[0050] Regarding the arrangement of the damping rod 3021, in some exemplary embodiments, the outer slide rail 1 is provided with a first support frame 303 and a second support frame 304, the first support frame 303 and the second support frame 304 are arranged at intervals along the sliding direction of the inner slide rail 2, and the two ends of the damping rod 3021 are respectively provided on the first support frame 303 and the second support frame 304.

[0051] In this way, the first support frame 303 and the second support frame 304 are arranged at intervals along the sliding direction, respectively fixing the two ends of the damping rod 3021, which can form two-point support for the damping rod 3021, and the support effect is stable. At the same time, the design of the first support frame 303 and the second support frame 304 facilitates the disassembly and replacement of the damping rod 3021.

[0052] Continuing with the existing damping rod 3021, in some exemplary embodiments, the damping rod 3021 is a threaded rod. Setting the damping rod 3021 as a threaded rod provides higher friction, resulting in higher damping force and better buffering effect in the damping mechanism 3.

[0053] For example, a rubber layer can be wrapped around the threaded rod. The threaded structure on the threaded rod allows the rubber layer to adhere more firmly to the damping rod 3021. The surface of the rubber layer is relatively rough. When the inner slide rail 2 slides relative to the outer slide rail 1, the rubber layer rubs against the wall of the damping hole 3011, resulting in better energy absorption.

[0054] For example, a threaded sleeve can be installed on the damping rod 3021. The threaded sleeve is threadedly connected to the damping rod 3021, and its position on the damper can be adjusted by screwing it to correspond to the position of the damping hole 3011. The outer wall of the threaded sleeve can be roughened to provide greater friction between the threaded sleeve and the wall of the damping hole 3011. Furthermore, the advantage of using a threaded sleeve is that it can be easily removed when worn and replaced, and only the threaded sleeve needs to be replaced, not the threaded rod itself.

[0055] Regarding the specific forms of the first support frame 303 and the second support frame 304, preferably, the second support frame 304 can be set as a "U" shape, with its opening facing the inner slide rail 2. The end of the second support frame 304 facing away from the opening is connected to the outer slide rail 1 by bolts. One end of the damping rod 3021 is inserted into the second support frame 304. A pin is used to pass through the second support frame 304 and the damping rod 3021 from one side of the second support frame 304, so that the end of the damping rod 3021 is pivotally connected to the second support frame 304. The first support frame 303 can be set as an "L" shape and connected to the outer slide rail 1 by bolts. The first support frame 303 is provided with a through hole so that the damping rod 3021 can pass through the through hole. Two nuts are screwed onto the damping rod 3021, with the two nuts on both sides of the first support frame 303 respectively. By tightening the two nuts towards the first support frame 303, the end of the damping rod 3021 that passes through the through hole can be fixed to the first support frame 303.

[0056] Still refer to Figures 1 to 3 Regarding the specific structure of the first damping part 301, in some exemplary embodiments, the first damping part 301 includes a first damping plate 3012 and a second damping plate 3013 having damping holes 3011, and a connecting plate 3014 connecting the first damping plate 3012 and the second damping plate 3013 together. The first damping plate 3012 and the second damping plate 3013 are respectively connected to the inner slide rail 2, and the first damping plate 3012 and the second damping plate 3013 are arranged at intervals along the sliding direction of the inner slide rail 2.

[0057] In these embodiments, a first damping plate 3012 and a second damping plate 3013 are provided, and damping holes 3011 are provided respectively. This enables the first damping part 301 and the damping rod 3021 to form two friction contact points. Compared with a single damping hole 3011 structure, the friction contact area is larger, which can better buffer sliding impact.

[0058] Meanwhile, the connecting plate 3014 connects the first damping plate 3012 and the second damping plate 3013 into a frame structure, which enhances the overall rigidity of the first damping part 301, reduces the risk of deformation or damage to the first damping part 301, and the symmetrical arrangement of the first damping plate 3012 and the second damping plate 3013 can balance the lateral force generated during the sliding process, ensuring that the inner slide rail 2 moves smoothly.

[0059] Regarding the connection method between the first damping part 301 and the inner slide rail 2, for example, it can be directly connected to the inner slide rail 2, or flanges can be arranged on both the first damping plate 3012 and the second damping plate 3013, and connected to the inner slide rail 2 through the flanges.

[0060] Furthermore, in some exemplary embodiments, the first damping part 301 is detachably connected to the inner slide rail 2. In another exemplary embodiment, the second damping part 302 is detachably connected to the inner slide rail 2.

[0061] As configured above, the first damping part 301 is detachably connected to the inner slide rail 2, or the second damping part 302 is detachably connected to the inner slide rail 2, which facilitates the separation of the first damping part 301 or the second damping part 302 from the inner slide rail 2, so as to remove the inner slide rail 2 and expose the internal first damping part 301 or the second damping part 302 for replacement.

[0062] Reference Figure 2 and Figure 4 As shown, in some exemplary embodiments, the locking mechanism 4 includes a locking unit 401 disposed on one of the first damping portion 301 and the second damping portion 302, and a locking hole 402 disposed on the other of the first damping portion 301 and the second damping portion 302. The locking unit 401 includes a housing 4011, a sliding portion 4012 slidably disposed within the housing 4011, and a locking pin 4013 with one end connected to the sliding portion 4012 and the other end extending out of the housing 4011. The locking pin 4013 is inserted into the locking hole 402, enabling the first damping portion 301 and the second damping portion 302 to be locked together.

[0063] Thus, the locking pin 4013 is inserted into the locking hole 402, and rigid locking is achieved through the mechanical structure. The structure is simple, the locking and unlocking actions are clear, and it is not easy to jam or mislock. In addition, the housing 4011 of the locking unit 401 and the sliding part 4012 have high matching precision, and the movement trajectory of the locking pin 4013 is accurate, which helps to improve the reliability of the locking mechanism 4.

[0064] To ensure the stable locking action of the locking mechanism 4, the housing 4011, sliding part 4012, and locking pin 4013 should all be made of high-strength materials, such as 304 stainless steel, 40MnB medium-carbon quenched and tempered alloy structural steel, and 20CrMnTi carburized steel. The connection between the housing 4011 and the first damping part 301 or the second damping part 302 must also have sufficient connection strength, for example, by bolting or welding. Alternatively, multiple locking mechanisms 4 can be provided, so that each locking mechanism 4 shares the load generated by preventing relative movement between the first damping part 301 and the second damping part 302, ensuring the stable locking of the locking structure 4.

[0065] Regarding the method of driving the sliding part 4012 to slide, in some exemplary embodiments, the housing 4011 is provided with gunpowder 403 and igniter 404, which is used to connect to the seat controller. Received from the control information of the seat controller, the igniter 404 can ignite the gunpowder 403, thereby driving the sliding part 4012 to slide relative to the housing 4011. The sliding part 4012 can then cause the locking pin 4013 to disengage from the locking hole 402, thus releasing the locking of the first damping part 301 and the second damping part 302.

[0066] Understandably, the high-pressure gas generated by the combustion of gunpowder 403 can quickly push the sliding part 4012, causing the locking pin 4013 to disengage from the locking hole 402. The unlocking response time is short, and compared with the traditional mechanical unlocking mechanism, the inner slide rail 2 can be unlocked more quickly, allowing the damping mechanism 3 to begin absorbing collision energy earlier. The igniter 404 is connected to the seat controller and can receive signals from components such as the vehicle collision sensor and seat belt pretensioner to achieve automated triggering of unlocking.

[0067] In addition, the seat controller can adjust the unlocking timing according to different scenarios to improve the accuracy of control. For example, the igniter 404 can be connected to the ECU (Electronic Control Unit) on the vehicle through the seat controller. When a collision occurs, the ECU sends control information to the seat controller, which in turn sends control information to the igniter 404, which then ignites the propellant 403 to burn.

[0068] The power cord of the igniter 404 can be routed through the housing 4011. It is necessary to protect the power cord and signal line of the igniter 404 from damage caused by the high temperatures generated during the combustion of the gunpowder 403. Specific measures could include attaching the igniter 404 inside the housing 4011, with the power cord and signal line extending out of the housing 4011, and installing a barrier between the igniter 404 and the housing 4011 to keep the power cord and signal line inside. For collision detection technologies and the specific selection of gunpowder 403 and igniter 404, please refer to relevant technical specifications.

[0069] For example, the housing 4011 can be cylindrical and fixed to the first damping plate 3012 of the first damping part 301. The sliding part 4012 is piston-shaped and disposed inside the housing 4011. One end of the locking pin 4013 is connected to the sliding part 4012, and the other end passes through the housing 4011. A locking hole 402 is provided on the damping rod 3021 for the locking pin 4013 to be inserted. The end of the housing 4011 away from the locking pin 4013 is provided with an exhaust hole 4014, so that after the gunpowder 403 burns and pushes the sliding part 4012, the sliding part 4012 can compress the gas inside the housing 4011 and discharge it through the exhaust hole 4014.

[0070] Of course, the housing 4011 can also be fixed on the damping rod 3021, and the locking hole 402 can be set on the second damping part 302, which can also enable the locking mechanism 4 to achieve the locking function.

[0071] In practice, after the gunpowder 403 is ignited and used, new gunpowder 403 needs to be added to the housing 4011 in a timely manner, and other parts need to be checked for damage. Any damaged parts should be replaced. At the same time, the first damping part 301 should be reset on the damping rod 3021, and the locking pin 4013 should be pulled out or pushed out of the housing 4011 and inserted into the locking hole 402.

[0072] It is worth noting that, regarding the locking component of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 4 As shown, it may include, for example, an outer slide rail 1, an inner slide rail 2 slidably disposed within the outer slide rail 1, a first support frame 303 and a second support frame 304 connected within the outer slide rail 1, a damping rod 3021 with its two ends respectively connected to the first support frame 303 and the second support frame 304, a first damping part 301 connected to the inner slide rail 2, and a locking unit 401 disposed on the first damping part 301.

[0073] The first damping part 301 includes a connecting plate 3014 and a first damping plate 3012 and a second damping plate 3013 vertically connected to both ends of the connecting plate 3014. The damping rod 3021 passes through the first damping plate 3012 and the second damping plate 3013.

[0074] The locking unit 401 includes a housing 4011 fixed on the first damping part 301. A piston-shaped sliding part 4012 is slidably provided inside the housing 4011. A locking pin 4013 is provided on the sliding part 4012. A locking hole 402 is provided on the damping rod 3021. When the locking pin 4013 is inserted into the locking hole 402, the inner slide rail 2 is locked relative to the outer slide rail 1.

[0075] The housing 4011 contains gunpowder 403 and igniter 404, and the igniter 404 is connected to the vehicle ECU via the seat controller.

[0076] In the preferred embodiment of the slide rail assembly above, the specific configuration and arrangement of the inner slide rail 2, outer slide rail 1, damping rod 3021, locking unit 401, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the inner slide rail 2, outer slide rail 1, damping rod 3021, locking unit 401, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0077] The slide rail assembly of this embodiment adopts the above design. By setting an outer slide rail 1 and an inner slide rail 2 that can slide relative to each other, and setting a damping mechanism 3 between the outer slide rail 1 and the inner slide rail 2, the outer slide rail 1 can be damped when it slides relative to the inner slide rail 2. At the same time, in conjunction with the locking mechanism 4, the inner slide rail 2 and the outer slide rail 1 can be locked in the normal state. After the locking mechanism 4 is unlocked, the inner slide rail 2 can move relative to the outer slide rail 1 to allow the damping mechanism 3 to absorb energy.

[0078] When the slide rail assembly is used in a vehicle, the outer slide rail 1 is connected to the vehicle and the inner slide rail 2 is connected to the seat. When the vehicle decelerates or stops in the event of a frontal collision, the seat and the occupants on it will have forward kinetic energy due to inertia, which may lead to a collision. At this time, the locking mechanism 4 is unlocked, and the first damping part 301 and the second damping part 302 will slide relative to each other to generate friction and consume kinetic energy, which plays a buffering role and reduces the impact on the occupants on the seat, thus improving the safety of the vehicle.

[0079] An embodiment of the second aspect of this application provides a slide rail assembly, referring to... Figure 5 and Figure 6 The slide rail assembly includes two sets of slide rail components arranged side by side, and a connector 5 connecting the inner slide rails 2 of the two sets of slide rail components together. The slide rail components are those of the embodiments of the first aspect of this application.

[0080] The slide rail assembly described in this application can share the weight and load of the seat by arranging two sets of slide rail components side by side, and has a strong load-bearing capacity. Secondly, the connector 5 connects the two sets of inner slide rails 2 into one, which enhances the rigidity of the overall structure and ensures that the two sets of inner slide rails 2 move synchronously during the sliding process, reducing seat tilting caused by jamming or offset of a single set of slide rails, and improving the smoothness and accuracy of seat adjustment.

[0081] Meanwhile, when the vehicle decelerates or stops in a head-on collision, the first damping part 301 and the second damping part 302 will slide relative to each other to generate friction and consume the collision energy, which will buffer the seats and occupants, reduce the impact on the occupants, and help improve the safety of the vehicle.

[0082] Specifically, refer to Figure 3 , Figure 5 and Figure 6 The two slide rail assemblies are arranged in parallel. Two connecting slots 501 can be provided at both ends of the connector 5. Two plugs 3015 on the first damping part 301 can be inserted into the connecting slots 501 to connect the first damping part 301 and the connector 5. Since the first damping part 301 is connected to the inner slide rail 2, the connector 5 can be connected to the two inner slide rails 2. The plugs 3015 on the first damping part 301 of the two slide rail assemblies are arranged facing each other to facilitate connection with the connector 5.

[0083] An embodiment of the third aspect of this application provides a vehicle in which the seat is mounted to the vehicle body via a slide rail assembly according to an embodiment of the second aspect of this application.

[0084] In practice, two support members 6 can be installed on the inner slide rail 2. The two support members 6 are located at both ends of the inner slide rail 2, and the seat is installed on the two support members 6 to achieve the connection between the seat and the inner slide rail 2.

[0085] The vehicle's control logic is as follows: When a collision occurs, it first determines whether the collision is a frontal collision. If it is a frontal collision, it then determines whether the seat is facing rearward. If the seat is facing rearward, it then determines whether the vehicle speed is greater than 20 km / h. If the vehicle speed is greater than 20 km / h, the igniter 404 ignites, and the propellant 403 burns, causing the locking pin 4013 to disengage from the locking hole 402, thus unlocking the damping mechanism 3. In all other cases, the igniter 404 will not ignite.

[0086] The vehicle described in this application has its seats mounted on the vehicle body via the aforementioned slide rail assembly. In the event of a frontal collision, the first damping part 301 and the second damping part 302 will slide relative to each other, generating friction to dissipate the collision energy, thus buffering the seats and occupants, reducing the impact on the occupants, and improving vehicle safety. At the same time, it works in conjunction with other vehicle safety systems, such as seat belt pretensioners and airbags, to improve the overall safety performance of the vehicle.

[0087] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
