Description

multifunctional car seat

technical field

The invention relates to a car seat, in particular to a multifunctional car seat.

Background technique

The shapes and functions of child safety seats on the market today are changeable. However, according to a survey, the utilization rate of child car safety seats in Chinese families is less than 5%. And disassembly is relatively unchanged. At present, child safety seats and car seats usually use a bundled connection method, that is, the child safety seat is tied to the car seat when in use. When not in use, because the car seat Occupying a child safety seat, so adults cannot ride, and the child safety seat needs to be disassembled. In addition, after the child safety seat is installed, its position relative to the car seat cannot be adjusted, that is, it cannot meet the needs of multi-functional use.

Contents of the invention

The purpose of the present invention is to overcome the disadvantages of the above-mentioned technologies, thereby providing a multi-functional car seat, which is convenient and safe to use and does not need to be disassembled and installed.

The technical scheme adopted in the present invention is as follows: a multifunctional car seat, including a base frame, an adult backrest inclined to the base frame, the base frame is provided with a base through the rotation of the rotating shaft, and the center line of the rotating shaft Parallel to the plumb line, the rear side of the base is rotatably provided with the lower end of the support frame, and the upper end of the support frame is rotatably connected with the child's backrest, and the base frame and the base are provided with two The locking mechanism is locked in multiple working positions. The child backrest has multiple working positions. When the child backrest is in the first working position, the child backrest is unfolded and attached to the surface of the adult backrest. When the child backrest is in the second working position In the working position, the child's backrest is folded on the base. When the child's backrest is in the third working position, the child's backrest is unfolded on the side of the adult backrest. When the child's backrest is in the fourth working position, the The child backrest unfolds directly against the adult backrest.

A further improvement is: in order to facilitate the conversion of the child's backrest in multiple working positions, the locking mechanism includes a gear fixed on the rotating shaft and a locking tooth slidingly arranged on the base frame. The gears are meshed, the center line of the gear coincides with the center line of the rotating shaft, and the locking tooth is connected with an operating traction cable. When changing the working position of the child's backrest, the locking tooth is driven by the operating traction cable to slide, so that the lock The tooth is separated from the gear, and then the base is rotated to change the position between it and the base frame. After the adjustment is in place, the traction cable is released, and the locking tooth is reset under the action of the reset elastic member, and the locking action is completed by meshing with the gear.

A further improvement is: in order to make the child's backrest more stable when it is unfolded, the rear side of the child's backrest is provided with a card slot that matches the support frame. When the child's backrest is unfolded, the support frame is inserted into the card slot of the child's backrest Inside, the support frame and the child's backrest form an integral structure, which improves stability and is more conducive to safe use.

A further improvement is: in order to improve safety, flexible wings are respectively provided on both sides of the base and the child's backrest.

A further improvement is that: for comfortable use, an adult headrest is provided on the adult backrest, and a child headrest is provided on the child's backrest.

A further improvement is: the two sides of the child's headrest are respectively provided with flexible side wings.

A further improvement is: for comfortable use, a height adjustment mechanism is provided between the child's headrest and the child's backrest.

A further improvement is that: the height adjustment mechanism includes a sliding chamber opened on the backrest of the child, a rack is provided on the child's headrest, the rack is inserted in the sliding chamber, and the sliding chamber The inner rotation is provided with positioning teeth meshed with the rack.

By adopting the aforementioned technical solution, the beneficial effects of the present invention are: diversified functions, when the child’s backrest is unfolded close to the adult’s backrest, it is only for children to sit on, and when the child’s backrest is folded on the base, it can be used as a car seat for adults to ride on When it is unfolded on the side of the adult's backrest, it can be used by the adult to hold the child sideways. When the child's backrest is unfolded to face the adult's backrest, it can be used by the child facing the adult. It is easy to adjust and safe to use.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-4, the present invention discloses a multifunctional car seat, comprising a base frame 1, an adult backrest 2 inclined to the base frame 1, and the base frame 1 is rotated by a rotating shaft 4 Base 3, the center line of the rotating shaft 4 is parallel to the vertical line, the rear side of the base 3 is rotated to be provided with the lower end of a support frame 9, and the upper end of the support frame 9 is rotatably connected to a child's backrest 5, so A locking mechanism is provided between the base frame 1 and the base 3 to lock the two in multiple working positions.

In order to facilitate adjustment, the locking mechanism includes a gear 6 fixedly arranged on the rotating shaft 4, a lock tooth 7 slidably arranged on the base frame 1, the lock tooth 7 meshes with the gear 6, and the The center line of the gear 6 coincides with the center line of the rotating shaft 4, and the lock tooth 7 is connected with an operation traction cable. When changing the working position of the child's backrest 5, the operation traction cable drives the lock tooth 7 to slide, so that the lock tooth 7 Disengage from the gear 6, and then turn the base 3 to change the position between it and the base frame 1. After the adjustment is in place, release the operation traction cable, the locking tooth 7 is reset under the action of the reset elastic member, and meshes with the gear 6 to complete the locking action.

In order to be suitable for different situations, the child's backrest 5 has multiple working positions.

When a child rides alone, that is, the child's backrest 5 is located under the first working position, the child's backrest 5 is unfolded and attached to the surface of the adult's backrest 2.
