The utility model discloses a voice coil motor, carrier, which is provided with a first through hole capable of placing a lens, and the side wall of the carrier is fixed with a coil, a base is provided with a second through hole coaxial with the first through hole, a spring piece is arranged between the carrier and the base, and the two sides of the spring piece are fixed with the carrier and the base respectively. The voice coil motor can balance the moment of force by canceling the upper spring and adjusting the lower spring wire width, can perfectly realize the use of one lower spring to carry the carrier, balance the moment of force, produce the tensile force opposite to the magnetic force, realize the use of one spring to realize the AF focusing stroke requirement, thereby reduce the cost.

The utility model discloses an automobile seat with a buffering anti-collision rear table plate structure, which comprises an automobile seat body, hinge support rods are hinged to two sides of the back of the automobile seat body, a seat table plate is hinged to the other ends of the hinge support rods, a through groove is formed in the right side of the seat table plate, and the through groove is communicated with the through groove. Mounting grooves are formed in the two sides of the inner wall of the left side of the through groove formed in the right side of the seat table plate, dampers are fixedly mounted in the mounting grooves, buffer plates are mounted at the output ends of the dampers, and telescopic springs surrounding the outer rings of the output ends of the dampers are mounted on the two sides of the left side of each buffer plate. By arranging the buffer plate, the damper, the telescopic spring and the like, a buffer effect is achieved when the seat table plate is impacted, the seat table plate is prevented from being impacted and further damaged, by arranging the baffle, the buffer plate and the like, a certain shielding effect is achieved, meanwhile, the impact stress area of the buffer plate is increased, and the service life of the seat table plate is prolonged. And the injury to passengers caused by collision is reduced.

The utility model discloses a material receiving mechanism for automatic production of materials. The material receiving mechanism comprises a material receiving roller way, a buffer baffle assembly and a driving assembly. The receiving roller way is provided with a receiving end and a discharging end and is used for conveying materials; the buffering baffle assembly is arranged near the discharging end of the material receiving roller way in a lifting mode and used for blocking materials and reducing the speed of the materials. The driving assembly is connected with the buffering baffle assembly and used for driving the buffering baffle assembly to move up and down to be higher or lower than the upper surface of the receiving roller way. The buffer baffle assembly comprises a lifting frame, a buffer plate and an elastic piece. The lifting frame is arranged near the discharging end of the material receiving roller way and connected with the driving assembly. The buffer plate is connected to the lifting frame and can ascend and descend together with the lifting frame. A gap is formed between the buffer plate and the lifting frame; the elastic piece is arranged between the lifting frame and the buffer plate, and the two ends of the elastic piece abut against the lifting frame and the buffer plate respectively. The material receiving mechanism for automatic production of the materials can slow down the material speed, and damage to the materials and a production line is avoided.
