[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0026] The sliding type of automobile auxiliary instrument panel is usually arranged on a slide rail mechanism. Figure 1 The slide rail mechanism includes an upper rail 20 and a lower rail 10. The upper rail 20 is arranged on the lower rail 10 and slides with the upper rail. The auxiliary instrument panel is arranged on the upper rail. The sliding of the upper rail on the lower rail is used to realize the sliding of the auxiliary instrument panel in the car.

[0027] The sliding safety locking device of the present invention is used for locking the slide rail mechanism, restricting the sliding of the upper rail on the lower rail, and playing the role of safely locking the auxiliary instrument panel of the automobile.

[0028] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments, the sliding safety locking device includes: The lock plate 501 disposed on the upper rail is rotated, the lock plate 501 includes two lock arms 5011, and the lock arms 501 extend toward a row of lock holes 106 disposed horizontally at intervals on the lower rail; The lock plate limiting assembly is used to limit the rotation of the lock plate when the lock plate rotates to a set angle; The lock plate resetting assembly is used to enable the lock plate to be in an unlocked state in a static free state, in which the two lock arms are arranged away from the lock hole of the lower rail, and when the external force acting on the lock plate is released, the lock plate can be restored to the unlocked state; When the movement acceleration of the upper rail reaches a set value, the lock plate 501 can overcome the action of the lock plate reset assembly and rotate under the driving force of inertia, so that one of the lock arms can be inserted into the lock hole to lock the upper rail.

[0029] When the vehicle is in an unlocked state, the lock plate is in an initial state under the action of the lock plate reset assembly. At this time, the two lock arms are arranged away from the lock hole of the lower rail, and will not affect the sliding of the upper rail on the lower rail. When the vehicle is in a sudden acceleration or sudden braking, the sub-instrument panel and the upper rail increase the instantaneous acceleration under the action of inertia. When the movement acceleration of the upper rail reaches the set value, the lock plate moving with the upper rail overcomes the action of the lock plate reset assembly and rotates under the driving force of the inertia, so that one of the lock arms rotates and is inserted into the lock hole on the lower rail. At this time, under the action of the lock plate limiting assembly, the movement of the upper rail in this direction can be limited by the interaction between the lock arm and the lower rail, thereby locking the upper rail.

[0030] The device is used for auxiliary safety locking of the automobile slide rail mechanism, which can avoid the injury to the occupants caused by the sliding of the automobile auxiliary instrument panel under the action of acceleration when other locking devices between the upper rail and the lower rail of the automobile slide rail fail or are accidentally unlocked, thereby ensuring the safety of the driver and passengers.

[0031] In some embodiments, the lock plate 501 includes a limit arm 5012, which is arranged relative to the two locking arms 5011, and in the rotation plane of the lock plate relative to the rotation center of the lock plate, the weight of the side where the two locking arms 5011 are located is greater than the weight of the side where the limit arm 5012 is located. The lock plate forms an uneven mass distribution on both sides relative to the rotation center. When subjected to acceleration in this direction, the side where the two locking arms are located can rotate under the action of inertia and drive the lock plate to rotate.

[0032] In some embodiments, the lock plate limit assembly includes two limit blocks 502 respectively arranged on both sides of the limit arm. When the limit arm 5012 rotates to abut against the limit block 502, the limit block can limit the rotation of the lock plate. At this time, the lock arm 5011 inserted into the lock hole interacts with the lower rail 10, which can limit the upper rail from continuing to slide in this direction, thereby locking the movement of the upper rail.

[0033] In some embodiments, the lock plate reset assembly includes two torsion springs 503 respectively arranged on both sides of the limit arm. The torsion spring 503 can apply a reset force to the limit arm to cause it to rotate in the opposite direction when the limit arm rotates, so that the lock plate can return to the unlocked state after the external force it is subjected to is released.

[0034] In some embodiments, when the limit arm 5012 is in the unlocked state, the two torsion springs 503 clamp the two sides of the limit arm 5012 to limit the rotation of the limit arm, thereby preventing the sliding safety locking device from interfering with the normal movement of the upper rail and preventing the lock plate from shaking and causing abnormal noise. Figure 3 The torsion arm of one torsion spring 503 abuts against one end face of the limiting arm, and the torsion arm of the other torsion spring 503 abuts against the other end face of the limiting arm. By setting the position between the two torsion springs 503 and the limiting arm 5012, the limiting arm can be limited and reset at the same time.

[0035] The lock plate reset component can also adopt a torsion spring structure, and a torsion arm of the torsion spring is fixedly connected to the limit arm, which can also play the role of limiting and resetting the limit arm.

[0036] In some embodiments, the two locking arms 5011 are symmetrically arranged relative to the limiting arm 5012, so that the mass distribution on the locking plate is more reasonable, and the device has the same locking performance in both directions.

[0037] Reference Figure 4 The two locking arms 5011 and the limiting arm 5012 form a Y-shaped structure, which further optimizes the structural layout of the locking plate and enables it to have better performance.

[0038] In some embodiments, one side of the locking end 5111 of the locking arm 5011 that interacts with the locking hole is set as a flat surface, and the other side is set as an arc surface. Figure 4 and Figure 6 The end of the locking arm 5011 inserted into the locking hole 106 is the locking end 5111. When the locking end is inserted into the locking hole, due to the relative movement between the locking plate and the lower rail, the outer side surface of the locking end acts on the locking hole, so that the locking plate is stuck in the locking hole. This side is set to a plane to form a good fit between the locking end and the locking hole; the other side of the locking end 5111 is set to an arc surface and extends to the end of the locking end, so that the end of the locking end forms a pointed end, and when the upper rail moves in the direction, the locking end can smoothly withdraw from the lock hole, which is convenient for the automatic unlocking operation of the device.

[0039] In some embodiments, the sliding safety locking device 50 includes a lock body 504, in which a cavity opened on one side is disposed, a lock plate 501 is rotatably disposed in the cavity of the lock body 504, and two lock arms 5011 extend from the opening to the outside of the lock body.

[0040] At this time, the lock plate limiting assembly and the lock plate resetting assembly can both be arranged on the lock body, and the sliding installation locking device is integrated with the lock body as a carrier, so that the device can be installed on the slide rail mechanism as an independent component.

[0041] On the other hand, the present invention further provides a vehicle slide rail mechanism. In some embodiments, the vehicle slide rail mechanism includes: A lower rail 10, on which a row of lock holes are arranged at intervals horizontally; An upper rail 20, which is disposed on the lower rail and slidably cooperates with the lower rail; And a sliding safety locking device 50, which is arranged on the upper rail 20 and is arranged opposite to the locking hole 106 on the lower rail 10, and is used to lock the movement of the upper rail on the lower rail.

[0042] On the other hand, the present invention further provides a vehicle auxiliary instrument panel module. In some embodiments, the vehicle auxiliary instrument panel module includes: Secondary instrument panel; And the automobile slide rail mechanism, the auxiliary instrument panel is arranged on the upper rail, when the auxiliary instrument panel moves on the lower rail under the action of inertia, the movement of the auxiliary instrument panel can be locked by the sliding safety locking device, thereby ensuring the safety of the sliding auxiliary instrument panel.

[0043] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship commonly placed when the product of the invention is used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In addition, if the terms "horizontal" or "vertical" appear in the description of the present invention, it does not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0045] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
