[Specific implementation method]
[0016] The sinking structure of a car seat according to the present invention is further described in detail below through specific embodiments.
[0017] like Figures 1 to 4As shown, a sinking structure of a car seat comprises a car body floor 1, a trunk floor 2 connected to the car body floor 1 and lower than the car body floor 1, and a car seat 3 arranged on the car body floor 1, a rotating motor 4 and a screw rod 5 are arranged at the bottom of the car seat 3, the rotating motor 4 is used to drive the screw rod 5 to operate, one side of the screw rod 5 is connected to a first connecting rod 6, the other end of the first connecting rod 6 is hinged to the trunk floor 2, the other side of the screw rod 5 is connected to a second connecting rod 7, the other end of the second connecting rod 7 is hinged to the trunk floor 2, a fourth connecting rod 9 is fixed to the bottom of the car seat 3, the middle part of the fourth connecting rod 9 is hinged to a third connecting rod 8, and the other end of the third connecting rod 8 is hinged to the trunk floor 2.
[0018] A front locking plate 10 is provided at the front end of the bottom of the car seat 3, a front lock buckle 11 matched with the front locking plate 10 is provided on the vehicle body bottom plate 1, a rear locking plate 12 is provided at the rear end of the bottom of the car seat 3, a rear lock buckle 13 matched with the rear locking plate 12 is provided on the vehicle body bottom plate 1, and a lock controller 14 for controlling the opening and closing of the front lock buckle 11 and the rear lock buckle 13 is provided on the car seat 3. A linkage cable 15 is connected to the front locking plate 10, and the other end of the linkage cable 15 is connected to the screw rod 5.
[0019] The vehicle seat 3 is provided with a folding motor 16 for folding the backrest of the vehicle seat 3 forward.
[0020] A torsion spring 17 is also provided at the hinged position of the other end of the first connecting rod 6 and the trunk bottom plate 2. The torsion spring 17 can assist in lifting the car seat 3 when it is lifted. When the car seat 3 sinks, the force of the torsion spring 17 can overcome the weight of the seat itself, allowing the car seat 3 to sink slowly.
[0021] A crossbeam 18 is provided at the bottom of the car seat 3, and two sides of the screw rod 5 form a quadrilateral structure through connecting plates 19 and the crossbeam 18, so as to increase the strength and stability of the screw rod 5 when rotating.
[0022] The working principle of the utility model is as follows: when working, the lock controller 14 controls the front lock buckle 11 and the rear lock buckle 13 to unlock, so that the front lock plate 10 is disengaged from the front lock buckle 11, and the rear lock plate 12 is disengaged from the rear lock buckle 13. After the folding motor 16 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 screw rod 5 to operate, and the rotation of the screw rod 5 drives the first connecting rod 6 and the second connecting rod 7 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, and at the same time, the third connecting rod 8 also rotates synchronously on the fourth connecting rod 9 to provide support for the car seat 3. When the car seat 3 gradually sinks, the linkage cable 15 is also contracted, so that the front lock plate 10 is close to the bottom of the car seat 3, so as to prevent the front lock plate 10 from interfering with the bottom plate of the car seat 3 when the car seat 3 sinks.
[0023] Compared with the prior art, the utility model has the following beneficial effects: the sinking structure of the above-mentioned car seat 3 adopts a motor to drive the screw rod 5, 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. It adopts an electric mode, which 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.
