[Specific implementation method]
[0016] The sinking structure of the automobile seat of the present invention is further described in detail below through specific embodiments.
[0017] like Figures 1 to 4As shown, the sinking structure of the car seat includes a body floor 1, a trunk floor 2 connected to the body floor 1 and lower than the body floor 1, and a car seat 3 arranged on the body floor 1, a rotating motor 4 and a rotating shaft 5 are arranged at the bottom of the car seat 3, and a recliner 6 is arranged on the rotating shaft 5. The rotating motor 4 is used to drive the recliner 6 to operate, and the middle part of the rotating shaft 5 is a linkage rod structure matched with the recliner 6. A first connecting rod 7 is connected to one side of the rotating shaft 5, and the other end of the first connecting rod 7 is hinged to the trunk floor 2, and a second connecting rod 8 is connected to the other side of the rotating shaft 5, and the other end of the second connecting rod 8 is hinged to the trunk floor 2. A fourth connecting rod 10 is fixed to the bottom of the car seat 3, and a third connecting rod 9 is hinged to the middle part of the fourth connecting rod 10, and the other end of the third connecting rod 9 is hinged to the trunk floor 2.
[0018] A front locking plate 11 is provided at the front end of the bottom of the car seat 3, a front lock buckle 12 matched with the front locking plate 11 is provided on the vehicle body bottom plate 1, a rear locking plate 13 is provided at the rear end of the bottom of the car seat 3, a rear lock buckle 14 matched with the rear locking plate 13 is provided on the vehicle body bottom plate 1, and a lock controller 15 for controlling the opening and closing of the front lock buckle 12 and the rear lock buckle 14 is provided on the car seat 3. A linkage cable 16 is connected to the front locking plate 11, and the other end of the linkage cable 16 is connected to the rotating shaft 5.
[0019] The vehicle seat 3 is provided with a folding motor 17 for folding the backrest of the vehicle seat 3 forward.
[0020] A torsion spring 18 is also provided at the hinged joint between the other end of the first connecting rod 7 and the trunk bottom plate 2. The torsion spring 18 can assist in lifting the car seat 3 when it is lifted. When the car seat 3 sinks, the force of the torsion spring 18 can overcome the weight of the seat itself, allowing the car seat 3 to sink slowly.
[0021] A crossbeam 19 is provided at the bottom of the car seat 3, and a quadrilateral structure is formed between the two sides of the rotating shaft 5 through the connecting plates 20 and the crossbeam 19, so as to increase the strength and stability of the rotating shaft during rotation.
[0022] The working principle of the utility model is as follows: when working, the lock controller 15 controls the front lock buckle 12 and the rear lock buckle 14 to unlock, so that the front lock plate 11 is disengaged from the front lock buckle 12, and the rear lock plate 13 is disengaged from the rear lock buckle 14. After the folding motor 17 is started, the backrest of the car seat 3 is folded forward, so that the car seat 3 is in a folded state. The rotating motor 4 drives the angle adjuster 6 to operate, and drives the rotating shaft 5 to rotate synchronously through the linkage rod structure. The rotation of the rotating shaft 5 drives the first connecting rod 7 and the second connecting rod 8 to rotate at the hinge point on the trunk bottom plate 2, so that the entire car seat 3 gradually moves toward the direction of the trunk and sinks. At the same time, the third connecting rod 9 also rotates synchronously on the fourth connecting rod 10 to provide support for the car seat 3. When the car seat 3 gradually sinks, the linkage cable 16 is also contracted, so that the front lock plate 11 moves closer to the bottom of the car seat 3 to prevent the front lock plate 11 from interfering with the bottom plate of the car seat 3 when the car seat 3 sinks.
[0023] The sinking structure of the car seat 3 adopts a motor-driven recliner 6, and realizes the sinking of the rear seat of the car through the rotating structure of the four-link, so that the rear seat of the car can sink to be flush with the bottom surface of the trunk, which not only improves the aesthetics, but also greatly improves the storage space of the trunk of the car. The electric mode makes the operation more labor-saving and simple.
[0024] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
