Background
A so-called car seat is a seat to be seated when sitting on.
The car seat can be roughly classified into: the front row seat comprises a headrest, a backrest, a cushion and armrests; rear seats: headrest, back, cushion, flank, handrail. The automobile seat can be divided into a split seat and a bench seat according to the shape; the functions can be divided into fixed type, detachable type and adjustable type; the number of people can be divided into single, double and multi-person chairs according to the number of the people sitting on the chair.
From the earliest fixed seats, to multifunctional power-adjustable seats, there are air cushion seats, power seats, stereo seats, mental recovery seats, to electronic adjustable seats, depending on the performance of the seat. The chair is divided into a leather chair, a flannelette chair and the like according to the material. There are also seats for special objects of use, such as children's seats and racing seats.
The driver and the passenger of the automobile seat provide a driving and sitting position which is convenient to operate, comfortable and safe, and the automobile seat has the following conditions:
1. the arrangement of the seats in the whole carriage is reasonable, and particularly, the driver seat must be in the optimal position;
2. the appearance design of the chair must accord with the physiological function of human body, and the appearance is attractive on the premise of ensuring the comfort;
3. the seat must be safe and reliable, should have sufficient strength, rigidity and durability, compact structure and reduce the mass as much as possible;
4. in order to satisfy the comfort of drivers and passengers, various adjusting mechanisms are provided with reliable locking devices to ensure safety.
In order to improve the applicability of the automobile seat to passengers with different heights, the seat is usually arranged on the slide rail in a sliding manner through the base, and a U-shaped pull rod is arranged to control the working state of a locking device of the slide rail. The pull rod is pulled upwards, and the base can move along the slide rail; and when the pull rod is put down, the sliding rail is locked by the locking device, and the base cannot move.
In actual use, when the slide rail locking device controlled by the pull rod fails or the locking force is insufficient, the automobile seat slides forwards during emergency braking of the automobile, so that a passenger can collide with a front object, and the safety of the passenger in the seat is reduced.
Disclosure of Invention
The invention aims to provide an automobile seat with a buffer device, and solves the problems that in actual use, when a slide rail locking device controlled by a pull rod fails or locking force is insufficient, the automobile seat slides forwards to cause passengers to bump a front object when an automobile is emergently braked, and the safety of the passengers sitting on the seat is reduced.
The invention is realized by the following technical scheme:
the automobile seat provided with the buffer device comprises an automobile seat body, a base, a seat slide rail and a U-shaped pull rod which are connected in sequence, the automobile seat body is arranged on the seat slide rail in a sliding way through the base, the tail ends of the pull rods are respectively connected with one seat slide rail and control the locking state of the locking device of the seat slide rail, a buffer component is arranged at one end of the base close to the pull rod, the buffer component comprises a contact block, a connecting shaft, a moving plate, a supporting shaft and a fixing plate which are connected in sequence, one end of the connecting shaft is connected with the contact block, the other end of the connecting shaft is connected with the movable plate, one end of the supporting shaft is connected with the fixed plate, the other end of the supporting shaft movably penetrates through the movable plate and then is in threaded connection with the limiting nut, the supporting shafts are provided with a plurality of springs, the axes of the supporting shafts are mutually parallel and are all parallel to the horizontal plane, and the supporting shafts are all sleeved with the springs;
the automobile seat body is moved along the seat slide rail, the contact block can be contacted with the pull rod, the moving plate is pushed to move, and the spring is in a compressed state.
In the invention, the buffer assembly is a core component, and plays a role in protecting passengers when a slide rail locking device controlled by the pull rod fails or the locking force is insufficient.
When slide rail locking means when pull rod control became invalid or locking force was not enough, when leading to the car seat body to slide because of the seat slide rail under the inertia effect when car emergency brake car, contact piece and pull rod contact, the movable plate moved to the base, and the spring is compressed gradually to reduce the removal speed of car seat body, avoid the condition that the passenger collided preceding object to appear then, protected passenger's life safety.
When the slide rail locking device controlled by the pull rod is in a normal working state and the seat needs to slide forwards for adjustment, the pull rod is pulled upwards, the automobile seat body is moved forwards, and then the pull rod is put down. When the automobile seat body is moved forwards, the contact block is not in contact with the pull rod, and when the automobile seat is moved, only the friction force between the base and the slide rail is overcome; when the seat is moved after the contact block is contacted with the pull rod, the friction force between the base and the slide rail and the compression deformation force of the spring need to be overcome.
Preferably, the spring is a cylindrical helical compression spring.
Preferably, there are two of the support shafts.
The two support shafts are arranged to enable the moving plate to move only along the axes of the support shafts.
Furthermore, a matching groove is formed in one end, in contact with the pull rod, of the contact block, the automobile seat body is moved along the seat slide rail, the middle section of the pull rod can be located in the matching groove, and the middle section of the pull rod is in contact with the bottom of the matching groove.
The pull rod is U-shaped, and it comprises a straight section and the vertical section that all sets up at two ends in straight section, the interlude be the straight section of pull rod.
The setting of cooperation groove has increased the contact surface of pull rod with the contact piece, and the condition of avoiding the contact piece to skid appears.
Further, the opening size of the fitting groove is larger than the groove bottom size. The opening size of the matching groove is larger than the bottom size of the groove, so that the middle section of the pull rod can be smoothly clamped into the matching groove.
Further, the bottom of the matching groove is concave into a semicircular shape, and when the pull rod is in contact with the matching groove, the pull rod is coaxial with the bottom of the matching groove. Therefore, the contact surface between the pull rod and the matching groove is maximized, and the stability of the compression spring is improved.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the automobile seat with the buffer equipment, when the sliding rail locking device controlled by the pull rod fails or the locking force is insufficient, so that the automobile seat body slides relative to the seat sliding rail under the inertia effect when an automobile is braked suddenly, the contact block is contacted with the pull rod, the moving plate moves towards the base, the spring is gradually compressed, the moving speed of the automobile seat body is reduced, the condition that a passenger collides with a front object is avoided, and the life safety of the passenger is protected;
2. according to the automobile seat with the buffering device, the arrangement of the matching groove increases the contact surface of the pull rod and the contact block, so that the sliding of the contact block is avoided;
3. according to the automobile seat provided with the buffer device, the size of the opening of the matching groove is larger than that of the bottom of the groove, so that the middle section of the pull rod can be conveniently and smoothly clamped into the matching groove.
