[0037] With the development of automobile technology and the increasing demand of consumers for comfort, more and more vehicles use the technology of slide rails. In the existing slide rail structure, the driving mechanism and the locking structure are independent systems. When the position of the slide rail needs to be adjusted, the locking structure needs to be unlocked, and then the driving mechanism needs to be adjusted. At this time, the seat is only locked by the driving mechanism. If a collision occurs at this time, the locking force of the driving mechanism is not enough, which can cause the upper and lower slide rails to separate, causing safety risks.
[0038] The main purpose of the present application is to provide a slide rail structure and a vehicle, which aims to solve the problem that the upper and lower slide rails are easily separated when the vehicle collides during the adjustment of the slide rail.
[0039] Please refer to Figure 1 The present application provides a slide rail structure 1000, which comprises a slide rail body 1, a locking structure 2 and an unlocking structure 3. The slide rail body 1 comprises a slidingly matched track 11 and a moving part 12, and the track 11 is provided with a first matching part 111. The locking structure 2 comprises a locking part 21, which is movably arranged on the moving part 12 and has a locking position for locking the first matching part 111 and an unlocking position away from the first matching part 111 in its movement stroke. The unlocking structure 3 comprises a transmission part 31, which is arranged on the moving part 12 and is in transmission connection with the locking part 21, so that when the transmission part 31 is subjected to an inertial force exceeding a preset value, the transmission part 31 drives the locking part 21 to move from the unlocking position to the locking position.
[0040] The technical scheme of the present application, by setting the locking structure 2, the locking structure 2 comprises the locking part 21, so that the moving part 12 can be locked relative to the track 11, thereby fixing the position of the moving part 12 without adjusting the moving part 12, and improving the stability of the slide rail structure 1000. Further, by setting the unlocking structure 3, the unlocking structure 3 comprises the transmission part 31, which drives the locking part 21 to move from the unlocking position to the locking position when subjected to an inertial force exceeding a preset value, so that when the locking part 21 is in the unlocking position and a collision occurs, the locking part 21 can be immediately moved to the locking position under the drive of the transmission part 31, realizing the locking of the moving part 12, preventing the derailment of the moving part 12 caused by sudden acceleration, and causing serious safety hazards. The present scheme has simple structure and adopts pure mechanical structure, which can ensure safety while reducing cost and facilitating assembly.
[0041] It is understood that the preset value is a pre-set critical value. When the vehicle is involved in an accident such as a collision or sudden braking that causes a sudden change in vehicle acceleration, since the track 11 is relatively fixed to the vehicle body, the moving part 12 tends to move relative to the track 11. In a specific reference frame, it can be assumed that the moving part 12 is subjected to an inertial force, the magnitude of which is positively correlated with the change in acceleration. At this time, since the slide rail structure 1000 is in the unlocked state, in order to ensure that the moving part 12 is relatively stationary, the only way to apply resistance is by relying on the motor that drives the moving part 12. In order to minimize the damage to the motor, a critical value for the magnitude of the inertial force is set. When the inertial force on the moving part 12 exceeds this critical value, the locking condition is triggered to provide an active locking function. At the same time, since braking and acceleration are inevitable during vehicle operation, in order to avoid interference to the system, the preset value can be increased, for example, the active locking condition will only be met when the acceleration is 10g, thus improving the anti-interference capability of this structure.
[0042] In one embodiment provided by the present invention, please refer to Figure 2 and Figure 3 To enable the transmission component 31 to drive the locking component 21, the transmission component 31 is rotatably mounted on the moving part 12 about the width of the slide rail, thus having a trigger position to move the locking component 21 to the locking position. The transmission component 31 is provided with a driving part 311. The locking component 21 is movably mounted on the moving part 12 in one direction, and the locking component 21 is provided with a second mating part 211. When the transmission component 31 is subjected to an inertial force exceeding a preset value, the driving part 311 drives the second mating part 211 to move the locking component 21 towards the locking position. This configuration, by rotating the transmission component 31 and moving the locking component 21 in one direction, converts the rotational stroke of the transmission component 31 into the linear movement stroke of the locking component 21. This facilitates the subsequent design of the intermediate transmission structure, and when a vehicle collision occurs, the collision signal can be easily converted into a rotation signal of the transmission component 31, making the design more rational.
[0043] It is understood that the trigger position is the position of the transmission component 31 when the transmission component 31 drives the locking component 21 to the locking position, which is also the position to which the transmission component 31 rotates when the vehicle is hit.
[0044] It needs to be explained that the application does not limit the connection relationship between the driving part 311 and the transmission part 31. In another embodiment, the driving part 311 is separately arranged from the transmission part 31, is arranged on the moving part 12 and is spaced from the transmission part 31 by rotating around the width direction of the slide rail, and is provided with a protrusion. The transmission part 31 is provided with an arc-shaped groove. When the transmission part 31 is in the trigger position, the groove drives the protrusion to rotate synchronously. When the transmission part 31 is away from the trigger position, the groove avoids the protrusion, and does not limit the movement of the driving part 311. That is, only when the collision condition is triggered, the transmission part 31 drives the driving part 311 to move, so as to drive the locking part 21 to move to the locking position.
[0045] It also needs to be explained that the application does not limit the specific transmission mode between the driving part 311 and the locking part 21. In a preferred embodiment, the driving part 311 is provided with a guide groove 3111. The second matching part 211 includes a guide column 2111 which extends into the guide groove 3111 and abuts against the groove wall in the width direction of the guide groove 3111, so as to drive the locking part 21 to move when the driving part 311 rotates. In this way, the structure is simple, easy to assemble, and the guide groove 3111 can drive the guide rod to move bidirectionally. Specifically, please refer to Figure 3 When the transmission part 31 rotates counterclockwise, the locking part 21 moves upward to the locking position. When the transmission part 31 rotates clockwise, the locking part 21 moves downward to the unlocking position.
[0046] In another embodiment, the driving part 311 is provided as a cam, the second matching part 211 is provided as a flat plate, and the locking part 21 has a locking position below and an unlocking position above. When the collision condition is triggered, the cam rotates to press the flat plate to drive the locking part 21 to move downward to the locking position. The locking part 21 is also provided with a reset device to automatically rebound to the unlocking position after the pressing of the locking part 21 is released. In this way, the driving part 311 and the locking part 21 only contact when work is needed, reducing the wear of the transmission part 31 and improving the service life of the device.
[0047] Further, the first matching part 111 and the locking part 21 are respectively provided with corresponding teeth which match with each other. In this way, the structure is simple, and the locking strength is high. By reducing the spacing between the clamping teeth, that is, by increasing the density of the clamping teeth, the cooperation success rate of the locking part 21 and the first matching part 111 during the movement of the moving part 12 can be improved. It can be understood that the motor driving the moving part 12 is correspondingly provided as a stepping motor, so as to ensure that the locking part 21 can cooperate with the first matching part 111 after adjusting the position of the moving part 12 each time.
[0048] In order to improve the rotational inertia of the transmission member 31, the counterweight part 32 is arranged on the transmission member 31, so that when the transmission member 31 is subjected to an inertia force exceeding a preset value, the counterweight part 32 drives the transmission member 31 to rotate towards the triggering position, so as to drive the locking member 21 to move from the unlocking position to the locking position. In this way, the triggering condition of the locking is controlled, and the preset value is designed by the weight of the counterweight part 32, so as to improve the sensitivity of the system.
[0049] Further, the slide rail structure 1000 further comprises a reset spring 4, one end of the reset spring 4 is connected with the counterweight part 32, and the other end is connected with the moving part 12, which is used for resetting the transmission member 31 away from the triggering position. In this way, when the transmission member 31 rotates to the triggering position, after the collision ends, the transmission member 31 is automatically away from the triggering position under the action of the reset spring 4, so as to drive the locking member 21 to move to the unlocking position, preventing the seat from being unable to be unlocked after the collision, so as to prevent the search personnel from being stuck by the seat. At the same time, the reset spring 4 is arranged on the counterweight part 32, which improves the reset torque, and further improves the response speed of the system.
[0050] It can be understood that the stiffness coefficient of the spring also affects the size of the preset value. By increasing the stiffness coefficient of the spring, the resistance that needs to be overcome by the transmission member 31 is greater, so as to increase the size of the preset value.
[0051] In order to realize the separate control of the locking member 21, please refer to Figure 1 and Figure 2 The locking structure 2 further comprises a driving mechanism 22, the driving mechanism 22 comprises a pressing member 221 and a driving device 222, the pressing member 221 is arranged corresponding to the locking member 21, and is used to drive the locking member 21 to move, and the driving device 222 is drivingly connected with the pressing member 221; the slide rail structure 1000 further comprises a self-locking switch 5, which is arranged between the locking member 21 and the moving part 12, so as to fix the locking member 21 to the locking position, or reset the locking member 21 to the unlocking position, when the pressing member 221 drives the locking member 21 to move. By arranging the self-locking switch 5 and driving the pressing member 221 to press, the unlocking and locking states of the locking member 21 are changed, so as to realize the self-resetting function. At the same time, the locking member 21 can be kept in the unlocking or locking state by the self-locking switch 5, and the structure is more stable.
[0052] Further, the driving device 222 comprises a synchronous rod 2221 and a locking motor 2222, the synchronous rod 2221 is rotationally arranged on the moving part 12 along the width direction of the track 11, the pressing piece 221 is arranged on the synchronous rod 2221 to rotate with the synchronous rod 2221, and the driving shaft of the locking motor 2222 is connected with the synchronous rod 2221 to drive the synchronous rod 2221 to rotate. It can be understood that the track 11 is provided with a pair, and the corresponding moving part 12 is also provided with a pair, the synchronous rod 2221 is arranged between the two tracks 11, and the self-locking motor is arranged at the middle part of the synchronous rod 2221, so that the arrangement is more reasonable, and since the motor is arranged at the middle part, it is not easy to interfere with other parts, and subsequent assembly is facilitated.
[0053] Further, the transmission member 31 is sleeved on the synchronous rod 2221 and gap-fitted with the synchronous rod 2221. Since the transmission member 31 and the synchronous rod 2221 are both rotationally arranged on the moving part 12, by coaxially arranging the mounting hole of the transmission member 31 and the mounting hole of the synchronous rod 2221, the structure is more compact, the arrangement space on the moving part 12 is saved, and other mechanisms are facilitated to be installed. It can be understood that the gap-fitted means that the transmission member 31 and the synchronous rod 2221 only have a limiting function, and do not have a transmission function.
[0054] The application further provides a vehicle comprising the slide rail structure 1000, since the vehicle comprises the slide rail structure 1000, the specific structure of the slide rail structure 1000 is referred to the above-mentioned embodiments, since the slide rail structure 1000 of the vehicle adopts all the technical solutions of the above-mentioned embodiments, at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
[0055] The above-mentioned is only an exemplary embodiment of the application, and does not limit the patent scope of the application, any equivalent structural transformation made by referring to the content of the specification and drawings of the application, or direct / indirect application in other related technical fields is included in the patent protection scope of the application.
