[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] A sliding car sub-dashboard is usually arranged on a slide rail mechanism, which includes an upper rail and a lower rail. The upper rail is arranged on the lower rail and slides with the upper rail. The sub-dashboard is arranged on the upper rail, and the sliding of the upper rail on the lower rail is utilized to realize the sliding of the car sub-dashboard in the car.

[0027] In order to ensure the safety of the auxiliary instrument panel in the car, a sliding locking device is needed to lock the position of the auxiliary instrument panel on the lower rail, and then the auxiliary instrument panel can be easily unlocked when the position of the auxiliary instrument panel needs to be moved.

[0028] By arranging a sliding locking device on the slide rail mechanism, the upper rail is locked and unlocked by the sliding locking device, thereby realizing the locking and unlocking operation of the auxiliary instrument panel.

[0029] Reference Figure 1 The slide rail mechanism includes an upper rail 20 and a lower rail 10. The upper rail 20 is disposed on the lower rail 10 and slides with the lower rail. In some embodiments, referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the sliding locking device comprises: The locking mechanism includes one or more locking rods 401 and a locking rod driving member 402. The locking rod 401 is slidably set on the upper rail and can move toward the locking holes 105 horizontally spaced on the lower rail. When the locking rod 401 is inserted into the locking hole 105, the upper rail is locked on the lower rail. When the locking rod is pulled out of the locking hole, the lock on the upper rail can be released.

[0030] The lock rod driving member 402 is used to apply force to the lock rod so that the lock rod is inserted into the locking hole, that is, the sliding locking device always locks the upper rail when in use, fixes the auxiliary instrument panel on the lower rail, and ensures the safety of the auxiliary instrument panel.

[0031] The lock rod driving component 402 can adopt an elastic component such as a torsion spring or a compression spring. The torsion spring or the spring applies a force to the lock rod to make it move toward the locking hole, so that the lock rod can always be stably inserted in the locking hole. The pre-tightening force provided by the torsion spring or the spring prevents the lock rod from generating noise due to the vibration of the vehicle body, etc., further ensuring the performance of the device.

[0032] The unlocking mechanism includes an unlocking member 403 slidably arranged on the upper rail, and the unlocking member 403 is arranged to be able to move in a direction perpendicular to the movement direction of the locking rod. Taking this embodiment as an example, the movement direction of the locking rod 401 is perpendicular to the sliding direction of the upper rail, and the movement direction of the unlocking member is the same as the sliding direction of the upper rail.

[0033] The driving mechanism 404 is used to drive the unlocking member to move, and when the driving mechanism drives the unlocking member to move, it can drive the lock rod to move in a direction away from the locking hole, so that the lock rod escapes from the locking hole, thereby realizing the unlocking operation of the upper rail. When the driving mechanism releases the action on the unlocking member, under the action of the lock rod driving member, the lock rod can be inserted into the locking hole again to lock the upper rail.

[0034] Through the cooperation among the lock rod driving member, the unlocking member and the lock rod, the lock rod can always keep stably locking the upper rail, thereby ensuring the safety of the use of the sliding auxiliary instrument panel.

[0035] The unlocking movement direction of the unlocking piece is set to be perpendicular to the movement direction of the locking rod, which is convenient for unlocking the sliding locking device at both ends of the auxiliary instrument panel. The impact force generated between the locking rod and the lower rail when the vehicle accelerates or brakes suddenly will not affect the unlocking mechanism, the transmission structure between the unlocking mechanism and the locking mechanism, and the driving mechanism. There will be no problem of mislocking under the action of external force, thereby ensuring the stability of the upper rail locking and the service life of the device.

[0036] In some embodiments, reference Figure 2 and Figure 3 The sliding locking device 40 includes a shell 405, which is a structure composed of an upper shell and a lower shell. A cavity is formed inside the shell 405. The locking rod 401 and the unlocking member 403 are respectively arranged in the shell 405 and slideably cooperate with the shell. At least one end of the locking rod 401 extends from the shell and is inserted into the locking hole 105 to lock the upper rail.

[0037] The locking rod and the unlocking member are integrated in the housing, which facilitates the installation and application of the device on the automobile slide rail mechanism.

[0038] In some embodiments, both ends of the locking rod 401 extend from the housing 405, and the two extended ends of the locking rod 401 are slidably matched with the housing. Based on the integrated structure of the locking rod and the unlocking member in the housing, the impact force generated between the locking rod and the lower rail is transmitted and acts on the housing, and the housing provides effective protection for other components of the device, further improving the stability of the device performance and service life.

[0039] In some embodiments, the unlocking member 403 includes a bracket 4032 and one or more driving blocks 4031 arranged on the bracket, the number of driving blocks 4031 corresponds to the number of locking rods, the driving blocks 4031 are respectively arranged on one side of the locking rod, the driving blocks 4031 are provided with a wedge surface set toward the locking rod, and the locking rod 401 is provided with a driving part 4011 that can form a sliding contact with the wedge surface when the unlocking member moves in a direction close to the locking rod.

[0040] When the driving mechanism drives the unlocking member to move, the wedge-shaped surface of the driving block cooperates with the driving part, and the wedge-shaped surface drives the lock rod to move in a direction away from the locking hole, so that the lock rod escapes from the locking hole, and the unlocking operation is realized. During the unlocking process, the lock rod compresses the elastic member, so that the lock rod can be inserted into the locking hole again after the unlocking action is released.

[0041] A plurality of ribs 406 are arranged at intervals in the housing 405 along the movement direction of the unlocking member. The ribs are provided with sliding grooves, and the bracket 4032 is fitted and clamped in the sliding grooves to achieve the sliding fitting arrangement of the unlocking member in the housing.

[0042] In some embodiments, the locking mechanism includes a plurality of locking rods 401 arranged side by side and spaced apart. By setting the spacing between the locking rods 401, the spacing between the locking holes, the width of the locking holes, and the spacing between the centers of the locking holes, at least one locking rod can be inserted into the locking hole when the upper rail moves to any position within its range of motion. In this way, when the upper rail slides to any position and needs to be locked at that position, at least one locking rod can be inserted into the locking hole of the lower rail, thereby ensuring the safety and reliability of locking.

[0043] Specifically, refer to Figure 3 , Figure 4 and Figure 5 The locking mechanism of this embodiment includes three locking rods 401 arranged side by side with equal intervals. The spacing between the locking rods 401 is set to 4 times the width of the locking rod. The widths of the locking holes 105 are the same and they are arranged at equal intervals. The spacing distance between adjacent locking holes is equal to the width of the locking rod and the spacing between the centers of the locking holes is 3 times the width of the locking rod.

[0044] In some embodiments, the driving mechanism 404 includes a pull rope connected to the unlocking member and a motor for driving the pull rope. The motor pulls or releases the pull rope to drive the unlocking member to move in the unlocking direction. Under the action of the locking rod driving member, through the cooperation between the locking rod and the unlocking member, the locking rod and the unlocking member are reset to the locked state when the pull rope is released.

[0045] The pull rope is made of steel wire rope, and a soft sleeve is arranged on the pull rope to facilitate pulling of the pull rope.

[0046] On the other hand, the present invention also provides a vehicle slide rail mechanism. In some embodiments, referring to Figure 1 , the automobile slide rail mechanism includes: A lower rail 10, on which a row of locking holes 105 are arranged at intervals horizontally; An upper rail 20, which is disposed on the lower rail and slidably cooperates with the lower rail; As for the sliding locking device in the above embodiment, the sliding locking device 40 is arranged on the upper rail 20 and is arranged opposite to the locking hole on the lower rail. The upper rail is locked by inserting the locking rod into the locking hole.

[0047] 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 in the automobile slide rail mechanism in the above embodiment, the auxiliary instrument panel is arranged on the upper rail; the auxiliary instrument panel can be fixed by locking the upper rail through the sliding locking device; when the sliding locking device is released, the auxiliary instrument panel can slide on the lower rail.

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.

[0049] 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.

[0050] 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.
