Technical Field

[0001] This utility model relates to seat locks, and more particularly to a seat lock with clutch transmission. Background Technology

[0002] Chinese utility patent CN221273311U discloses an electrically controlled unlocking mechanism. The motor drives the rotating rod to rotate, and the rotating rod pushes the sliding rod to move, thereby causing the sliding rod to drive the first rotating plate and the second rotating plate to rotate. This simplifies the transmission structure and requires less installation space. However, if the motor continues to rotate after the rotating rod pushes the sliding rod into place due to a malfunction, the transmission structure will be jammed, and there is a risk of damage to the components. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a seat lock with clutch transmission. The design is that the first end face gear and the second end face gear mesh to participate in the transmission. After the drive block is in place, the first end face gear and the second end face gear repeatedly engage and disengage in the left and right directions, so that the transmission structure will not be jammed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This type of clutch-driven seat lock includes a sealing plate, a cable plate, and a buckle plate.

The driving block has a first inclined surface and a transmission block, which has a second inclined surface. The transmission block is rotatably arranged, wherein the area between the first and second inclined surfaces is defined as the inner side. A first end face gear is provided on the outer side of the transmission block, and the first end face gear meshes with a second end face gear. The second end face gear is connected to a motor for transmission. A second return spring is provided on the outer side of the driving block.

[0005] In this scheme, after the drive block moves into place, the motor continues to rotate. The first end face gear remains stationary with the drive block, while the second end face gear rotates with the motor. The second return spring keeps the first end face gear and the second end face gear connected, and the first end face gear and the second end face gear continuously engage and disengage.

[0006] Preferably, the buckle plate and the cable plate are rotatably mounted on the mounting plate, the cable plate is provided with a driven part, and the mounting plate is provided with a first limiting hole for the driven part to extend into and move.

[0014] Preferably, the buckle plate and the cable plate are rotatably disposed on the front side of the mounting plate, and a cover is connected to the rear side of the mounting plate. A pad is provided inside the cover, and a mounting cavity is formed between the pad and the cover. The motor, the second end face gear, the transmission block and the drive block are disposed in the mounting cavity.

[0015] In this design, the installation cavity is waterproof and dustproof.

[0016] Preferably, the second end face gear is provided with a limiting ring, and the wall of the mounting cavity is provided with an annular groove that cooperates with the limiting ring.

[0017] In this design, the limiting ring restricts the second end face gear from shifting in the left and right directions.

[0018] Preferably, the driving block is provided with a driving part that extends into the first limiting hole, the driving part abutting and cooperating with the driven part, and the pad is provided with a second limiting hole for the driving part to pass through and move left and right.

[0019] In this design, the wall of the second limiting hole limits the drive unit.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0033] See appendix Figure 1-7In this embodiment, a clutch-driven seat lock includes a sealing plate, a cable plate, and a buckle plate. The sealing plate cooperates with the buckle plate. The buckle plate and the cable plate are rotatably disposed on the front side of the mounting plate. The buckle plate is connected to the cable plate through a first return spring. The cable plate has a driven part. The mounting plate has a first limiting hole for the driven part to extend and move. The driving block has a driving part extending into the first limiting hole. The driving part abuts against the driven part. The first limiting hole is L-shaped. The pad block has a second limiting hole for the driving part to pass through and move left and right. The driving block is rotatably disposed. The driving block has a first inclined surface. The driving block is equipped with a transmission block. The transmission block has a second inclined surface. The transmission block is rotatably disposed.

[0034] The inner side is defined as the area between the first inclined surface and the second inclined surface. A first end face gear is provided on the outer side of the transmission block, and the first end face gear meshes with a second end face gear. The second end face gear is connected to the motor for transmission. A mounting groove is provided on the outer side of the drive block, and a mounting shaft extending into the mounting groove is provided on the inner side of the transmission block. A through hole is provided at the bottom of the mounting groove for the mounting shaft to pass through. A second return spring is sleeved on the mounting shaft. A cover is connected to the rear side of the mounting plate, and a pad is provided inside the cover. A mounting cavity is formed between the pad and the cover. The motor, the second end face gear, the transmission block, and the drive block are disposed in the mounting cavity. The second end face gear is provided with a limiting ring, and the cavity wall of the mounting cavity is provided with an annular groove that cooperates with the limiting ring.

[0035] In this embodiment, the motor drives the second end face gear to rotate, and the first end face gear meshing with the second end face gear drives the transmission block to rotate. The second inclined surface rotates, while the first inclined surface remains stationary. The contact position between the protrusion of the driving block and the second inclined surface changes, and the driving block moves to the right relative to the transmission block. The driving block pushes the cable plate to rotate through the driving part, and the cable plate pulls the buckle plate to rotate through the first return spring. The buckle plate leaves the sealing plate slot to complete the unlocking. When locked, the driving block moves to the left relative to the transmission block, and the cable plate and buckle plate are reset due to the elastic force of the first return spring.

[0036] The motor output shaft is connected to the rotating block, and the rotating block is engaged with the second end face gear. The cavity wall guides the left and right movement of the drive block and the rotation of the transmission block. The first and second inclined surfaces are inclined relative to each other in the left and right directions and are respectively set to form grooves and protrusions along the circumference. During the rotation of the transmission block, the protrusion of the drive block leaves or enters the groove along the second inclined surface, so that the drive block moves left and right relative to the transmission block. Alternatively, the protrusion of the transmission block can move along the first inclined surface. The second return spring keeps the first end face gear and the second end face gear in contact. After the drive block moves to the right, the engagement and disengagement are repeated to avoid jamming. It can limit the right movement of the drive block and limit the swing of the cable plate to achieve the limit of the drive block.

[0037] In other alternative embodiments, the transmission block may be sleeved with the second end face gear; the mounting shaft may be disposed on the drive block, and the transmission block may be sleeved on the mounting shaft.

[0038] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
