Description

Technical Field

[0001] The invention belongs to the field of child seats, and in particular relates to a roller lifting mechanism for a vehicle-mounted seat. Background Art

[0002] A car child seat is a seat specially designed to protect the safety of child passengers in the car during driving. The main feature of this seat is that it is equipped with a seat belt that can firmly fix the child in the seat.

[0003] It is the responsibility of every driver to use a child seat in the car. This is not only because it can effectively protect the safety of children and prevent injuries in accidents, but also in many places, if the child passengers in the car do not use the correct safety seat, the driver may be fined for violating traffic regulations.

[0004] The patent with publication number CN305916699S and patent name “Child Seat” shows a very classic style of vehicle-mounted child seat. It is detachable, but after disassembly, it is inconvenient to carry due to its large size and single function.

[0005] In the patent application with publication number CN304363336S and name "Car Child Seat Base Cart", a cart installed at the bottom of the car child seat was invented. After the car child seat is removed from the car, it can be installed on this patented product and used as a cart. However, its disadvantage is that it adds a cart, which occupies the carrying space of the car and has very limited usage scenarios.

[0006] Therefore, the market needs a foldable and deployable roller system mounted on a vehicle child seat, so that the vehicle child seat can be used as a stroller after being removed from the car seat. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a vehicle-mounted child seat roller lifting mechanism capable of using the vehicle-mounted child seat as a stroller in view of the current status of the above-mentioned prior art.

[0008] The technical solution adopted by the present invention to solve the above technical problems is: a vehicle-mounted seat roller lifting mechanism comprises a storage slot arranged on the vehicle-mounted seat body for storing the landing gear, a rotating shaft for the landing gear to rotate is also arranged in the storage slot, a roller is connected to the free end of the landing gear, and a first limit pin is arranged on the landing gear to slide along the length direction of the landing gear;

[0009] The receiving groove is provided with a first limiting portion facing the ground, and the first limiting pin is used to press against the first limiting portion after the landing gear is deployed to prevent the landing gear from falling back into the receiving groove;

[0010] The inner wall of the storage slot is also provided with a second limit portion facing away from the ground, which is used to prevent the landing gear from being deployed due to the influence of gravity after the landing gear falls back into the storage slot;

[0011] A displacement channel for the first limit pin to move is provided between the first limit portion and the second limit portion; the first limit portion and the second limit portion can be grooves opened on the inner wall of the storage groove, or can be protrusions arranged on the inner wall of the storage groove, and they can exist separately or in pairs. As for the displacement channel, it is only a space for the first limit pin to move.

[0012] The first limit pin is connected with a displacement pusher, and the displacement pusher is used to push the first limit pin away from the second limit pin. The displacement pusher can be an integral part of the first limit pin, or a separate part. Such a structure enables the landing gear to be deployed or stored from the storage slot.

[0013] In a preferred solution, a first elastic member is provided on the landing gear, and the first elastic member is used to push the first limit pin toward the second limit portion. The first elastic member can ensure that the first limit pin is limited to the second limit portion when the landing gear is stored in the storage slot.

[0014] In a preferred solution, the first limit portion, the displacement channel and the second limit portion are respectively located on the inner wall of the receiving groove, and the distance between the first limit portion and the rotating shaft is greater than the distance between the second limit portion and the rotating shaft. In this way, after the landing gear is deployed, the fulcrum of the landing gear can be close to the roller, thereby enhancing the rigidity of the landing gear.

[0015] In a preferred solution, the displacement pushing part includes a first slider fixed on the first limiting pin, the first slider is provided with a first paddle, and the first paddle is parallel to the rotating shaft. The first paddle is more convenient for fingers to paddle.

[0016] In a preferred solution, a third limiting portion is further provided in the storage slot, which is used to clamp the first limiting pin together with the first elastic member after the landing gear is deployed. A torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are connected to the landing gear and the inner wall of the storage slot, which is used to provide elastic potential energy for the landing gear to pop out. In this way, when the first limiting pin pushes away from the second limiting portion, the landing gear can pop out immediately.

[0017] In another embodiment, the displacement pushing portion includes a second slider fixed on the first limit pin, and a wedge block pressed against the second slider, the wedge block is located between the second slider and the roller, and the inclined surface of the wedge block faces the second slider, and when the wedge block is pressed, the first limit pin can be pushed away from the second limit portion.

[0018] The technical scheme of the same general inventive concept of the vehicle seat roller lifting mechanism also includes: comprising a storage slot provided in the vehicle seat body for storing the landing gear, a rotating shaft for the landing gear to rotate is also provided in the storage slot, and a roller is connected to the free end of the landing gear, wherein: a second limit pin is telescopically provided on the landing gear, and a first positioning hole is provided in the storage slot, so that the second limit pin abuts against the first positioning hole after the landing gear is deployed to prevent the landing gear from falling back into the storage slot;

[0019] A second positioning hole is also provided in the storage slot, which is used to prevent the landing gear from being deployed due to the influence of gravity after the landing gear falls back into the storage slot;

[0020] A third sliding block is arranged on the second limiting pin, and a second elastic member supported on the third sliding block is arranged in the landing gear, and the extension direction of the second elastic member is parallel to the second limiting pin.

[0021] In a preferred solution, a second paddle is provided on the third sliding block, and the second paddle is perpendicular to the second limiting pin.

[0022] A torsion spring is sleeved on the rotating shaft, and two ends of the torsion spring are connected to the landing gear and the inner wall of the storage slot, so as to provide elastic potential energy for the landing gear to pop out.

[0023] In summary, compared with the prior art, the utility model can be equipped with rollers and is easy to store and unfold. When installed on a car seat, the rollers can be stored in the storage grooves, and can be used as a cart after being removed from the car seat. BRIEF DESCRIPTION OF THE DRAWINGS
