Description

Technical Field

[0001] The utility model relates to a linear electric lock bolt for an automobile seat backrest. Background Art

[0002] The linear electric lock bolt for an automobile seat backrest is mainly used for fixing the rear seats. With the development of technology, the seat lock bolt can cooperate with the seat for adjustment. The existing linear electric lock bolt for an automobile seat backrest usually includes a mounting plate, a driving component, a lock buckling plate, and a guiding groove. A transmission rod is connected between the lock buckling plate and the driving component. The transmission rod is driven by the driving component to perform linear motion, so as to drive the lock buckling plate to move in the same direction on the guiding groove, thereby adjusting the angle of the seat. However, in the existing linear electric lock bolt for an automobile seat backrest, the connection between the connecting rod and the lock buckling plate and the connection between the lock buckling plate and the guiding groove are relatively weak, and are easily damaged when the seat is impacted, resulting in the failure of the linear electric lock bolt for an automobile seat backrest. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a linear electric lock bolt for an automobile seat backrest, so as to improve the connection strength between the transmission rod and the lock component and the connection strength between the lock component and the guiding groove.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A linear electric lock bolt for an automobile seat backrest, including a mounting seat, a transmission rod, a lock component and a driving component which are all arranged on the mounting seat. One side of the transmission rod is installed on the driving component and is driven by the driving component to perform linear motion. The other side of the transmission rod is fixedly connected to the lock component by a rivet. A guiding groove parallel to the transmission rod is arranged on the mounting seat. The lock component is driven by the transmission rod to move in the guiding groove. The lock component includes a sliding seat, a lock buckling plate installed on the sliding seat, and a pair of guiding components installed on the sliding seat. The sliding seat moves on the guiding groove through the guiding components. The transmission rod is fixedly connected to the sliding seat by a rivet, and at least two rivets are provided.

[0005] As a further improvement of the utility model, the guiding component includes a bolt and a slider. The head of the bolt abuts against the bottom of the mounting seat, and the screw of the bolt penetrates through the guiding groove and is threadedly connected to the sliding seat. A flange abutting against the inner wall of the guiding groove is arranged on the screw of the bolt. The slider is installed between the sliding seat and the mounting seat and is sleeved on the flange. Clasps for clamping the sliding seat are arranged on both sides of the slider, and an installation opening for the clasps to extend out and clamp is arranged on the sliding seat.

[0006] As a further improvement of the utility model, the claws of the clasps on the pair of sliders close to each other are clamped in the same clamping opening of the sliding seat, and the number of the clamping openings is one.

[0007] As a further improvement of the present utility model, the bottom surface of the slider facing the mounting seat is arched. When the bolt is screwed tightly with the sliding seat, pressure is applied to the slider to cause deformation of the slider; the slider not only applies pressure to the sliding seat and the mounting seat in the reverse direction to eliminate the gap and prevent abnormal noise during the sliding of the bolt, but also avoids the close contact of surface with surface, reducing the frictional resistance.

[0008] As a further improvement of the present utility model, the mounting seat is provided with plastic coating at the position corresponding to the guiding groove. The coating covers the end faces on both sides of the guiding groove and the inner wall surface of the guiding groove. The flange of the bolt abuts against the surface of the coating covering the inner wall of the guiding groove, and the head of the bolt and the bottom of the slider respectively abut against the end faces on both sides of the coating.

[0009] As a further improvement of the present utility model, a reinforcing plate is welded between the locking rods of the lock.

[0010] As a further improvement of the present utility model, the mounting seat is provided with a window facilitating the installation of rivets on the moving track corresponding to the connection between the sliding seat and the transmission rod.

[0011] The beneficial effects of the present utility model: By arranging two rivets at the connection between the transmission rod and the sliding seat, the connection strength is improved. The sliding seat moves on the guiding groove through a pair of guiding components. When the lock is locked and stressed, the lock and the transmission rod will be subjected to a moment and tend to rotate around the guiding components. The guiding components are arranged in pairs, which can improve the connection strength and further prevent the relative rotation between the lock and the transmission rod, improving the running stability of the locking bolt.

Detailed implementation mode

[0019] The following will further elaborate on the present utility model in conjunction with the embodiments given in the accompanying drawings.

[0020] Refer to Figures 1-6 As shown, a linear electric lock bolt for an automotive seat backrest includes a mounting seat 1, a transmission rod 2, a locking component 3 and a driving component 4, all of which are arranged on the mounting seat 1. One side of the transmission rod 2 is mounted on the driving component 4 and performs linear motion driven by the driving component 4. The other side of the transmission rod 2 is fixedly connected to the locking component 3 through a rivet 5. When the driving component 4 drives the transmission rod 2 to move, the locking component 3 moves in the same direction as the transmission rod 2. A guiding groove 101 parallel to the transmission rod 2 is provided on the mounting seat 1. The locking component 3 is driven by the transmission rod 2 to move in the guiding groove 101. The provision of the guiding groove 101 enables the movement of the locking component 3 to be stable. The locking component 3 includes a sliding seat 301, a lock 302 mounted on the sliding seat 301, and a pair of guiding components 303 mounted on the sliding seat 301. The sliding seat 301 moves on the guiding groove 101 through the guiding components 303. The transmission rod 2 is fixedly connected to the sliding seat 301 through a rivet 5. At least two rivets 5 are provided. This technical solution improves the connection strength by providing two rivets 5 at the connection between the transmission rod 2 and the sliding seat 301. Even if one of the rivets 5 is damaged, it will not cause looseness at the connection between the transmission rod 2 and the sliding seat 301. The sliding seat 301 moves on the guiding groove 101 through the pair of guiding components 303, further preventing the sliding plate from rotating relative to the transmission rod 2 while improving the connection strength.

[0021] The guiding assembly 303 includes a bolt 3031 and a slider 3032. The head of the bolt 3031 abuts against the bottom of the mounting base 1, and the screw of the bolt 3031 passes through the guiding groove 101 and is threadedly connected to the sliding seat 301. The head of the bolt 3031 is larger than the diameter of the guiding groove 101 to prevent the head from passing through the guiding groove 101. A flange 3033 is provided on the screw of the bolt 3031 and abuts against the inner wall of the guiding groove 101. The flange 3033 restricts its movement along the direction of the guiding groove 101 by abutting against the inner wall of the guiding groove 101. The slider 3032 is installed between the sliding seat 301 and the mounting base 1 and sleeved on the flange 3033. Clasps 3034 for clamping the sliding seat 301 are provided on both sides of the slider 3032. An installation opening 304 for the clasps 3034 to protrude and engage is provided on the sliding seat 301. The slider 3032 and the head of the bolt 3031 form a clamping force on the guiding groove 101, enabling the sliding seat 301 to move along the guiding groove 101. By providing the clasps 3034 on the slider 3032 and arranging the clasps 3034 in the installation opening 304, the rotation of the slider 3032 relative to the sliding seat 301 can be restricted. In this embodiment, the number of installation openings 304 is one. The claws of the clasps 3034 on the adjacent sliders 3032 are engaged in the same installation opening 304. To improve the stability of the guiding assembly 303, the bottom surface of the slider 3032 facing the mounting base 1 is arched. The arched bottom surface can undergo elastic deformation to absorb part of the energy caused by the impact of the seat. When the bolt is tightened with the sliding seat in a threaded manner, pressure is applied to the slider to deform it; the slider not only reversely applies pressure to the sliding seat and the mounting base to eliminate the gap and prevent abnormal noise during the sliding of the bolt, but also avoids the close contact of surfaces, reducing the frictional resistance.

[0022] A plastic coating 6 is provided at the position of the mounting base 1 corresponding to the guiding groove 101. The plastic coating 6 covers the end faces on both sides of the guiding groove 101 and the inner wall surface of the guiding groove 101. The flange 3033 abuts against the surface of the plastic coating 6 covering the inner wall of the guiding groove 101. The head of the bolt 3031 and the bottom of the slider 3032 respectively abut against the end faces on both sides of the plastic coating 6. The plastic coating 6 is provided to reduce the sound generated when the guiding assembly 303 moves. A reinforcing plate 8 is welded between the locking rods of the lock 302. The reinforcing plate 8 is provided to enhance the strength of the lock 302. A window 7 facilitating the installation of the rivet 5 is provided on the mounting base 1 along the movement trajectory of the connection between the sliding seat 301 and the transmission rod 2. The window 7 is provided to facilitate the riveting of the transmission rod 2 and the movable seat.

[0023] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
