Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seat protection structures, in particular to a child protection device on a vehicle. Background Art
[0002] The car is provided with a device for installing a child seat on the seat behind the driver for connecting the child seat to protect the child. In addition to the lock buckle on the seat cushion, the rear seat is also fixed with a hook at the back of the seat. The bottom of the child seat cooperates with the lock buckle at the seat cushion through the lock hook, and the top of the child seat is connected to the ring buckle through a pull rope, and the ring buckle is hung on the hook on the back of the seat, thereby achieving the effect of three-point locking of the child seat, making the installation of the child seat more stable and firm. At present, an opening is provided at the bottom of the hook at the back of the seat to facilitate the ring buckle to be hung on the hook from the opening, resulting in an unreliable connection between the ring buckle and the hook. When the pull rope is not tightened to make the ring buckle press against the inner top wall of the hook, the ring buckle is easy to slip from the opening at the bottom of the hook, resulting in unhooking. When the car is impacted, the bearing capacity of the child seat changes from three-point force to two-point force, and uneven force is easy to cause detachment, which is very dangerous. Utility Model Content
[0003] The utility model aims to overcome the deficiencies of the prior art and provide a child protection device for a vehicle, which has a more stable and secure locking structure and will not cause the problem of unhooking, thereby improving the protection strength for children.
[0004] The objective of the utility model is achieved through the following technical scheme: a child protection device on a vehicle, comprising a hook installed on the back of a seat, the hook comprising a long cross bar, a short cross bar, a vertical bar and a telescopic rod, one end of the long cross bar is fixedly connected to the back of the seat, the bottom of the other end of the long cross bar is fixedly connected to one end of the vertical rod, the other end of the vertical rod is fixedly connected to the short cross bar on a side close to the back of the seat, the short cross bar is parallel to the long cross bar, and the end of the short cross bar away from the vertical rod is hinged to the telescopic rod, and the seat back is provided with an abutment groove. Under normal conditions, the telescopic rod is extended and abuts against the inner bottom wall of the abutment groove. When installed, the telescopic rod contracts and deflects downward to disengage from the abutment groove.
[0005] Furthermore, the telescopic rod comprises a fixed rod and a movable rod, one end of the fixed rod is hinged on the short cross bar, and the other end is slidably penetrated by the movable rod.
[0006] Furthermore, a sliding groove is provided at one end of the fixed rod away from the short cross rod, and one end of the movable rod is slidably adapted in the sliding groove. A spring is provided in the sliding groove, and two ends of the spring are respectively connected to the fixed rod and the movable rod. When the spring is in a normal state, the end of the movable rod away from the fixed rod abuts against the inner bottom wall of the abutting groove.
[0007] Furthermore, strip grooves are provided on both sides of the fixed rod, the strip grooves are connected to the sliding grooves, and shift rods are connected to both sides of the movable rod, and the shift rods pass through the strip grooves on the same side.
[0008] Furthermore, threaded holes are provided on both sides of the moving rod, a threaded column is fixed to one end of the shifting rod, and the threaded column is threadedly connected in the threaded hole.
[0009] Furthermore, the telescopic rod is hinged on the short cross bar through a torsion spring, and when the torsion spring is in a normal state, the telescopic rod deflects downward and separates from the abutting groove.
[0010] Furthermore, a U-shaped opening is provided at one end of the short cross bar away from the vertical bar, a hinge shaft is fixedly passed through the telescopic rod, both ends of the hinge shaft are equipped with the torsion springs, a torsion spring hole is provided on the side wall of the U-shaped opening, and the torsion spring is adapted in the torsion spring hole.
[0011] The beneficial effects of the utility model are:
[0012] When the ring buckle of the child seat is installed, the telescopic rod shrinks and disengages from the abutment groove, so that an opening for the ring buckle to pass through is formed at the bottom of the hook, which facilitates the ring buckle to be hung on the hook. After the ring buckle is installed, the telescopic rod is deflected upward and extended to abut against the inner bottom wall of the abutment groove, so that the hook and the seat back form a closed ring. Even if the pull rope is tightened, the ring buckle will not disengage from the hook, which greatly improves the usability and installation of the child seat and enhances the protection of children.
