Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to figures 1-3: in the embodiment, a movable child car seat, including cushion 1, back cushion 2 and cushion 7, handrail 6 is installed to the outer wall outside of cushion 1 and cushion 7, the upper end center of cushion 7 is fixed continuous through end area 8 and end area buckle 9, the terminal joint in top of end area buckle 9 has hasp 13, handle 12 is installed at the front end center of hasp 13, end area buckle 9 is usually fixed with hasp 13 lug connection, do not receive the removal when handle 12 rotates, control module 3 is installed to the front side of end area buckle 9, inside the running through of both sides of back cushion 2 has baldric 4, and the end of baldric 4 is fixed continuous with shoulder belt buckle 5, inside the running through of the below of handrail 6 has sideband 11, and the end of sideband 11 is fixed continuous with sideband buckle 10, the rear end of cushion 7 passes through back cushion 1 and links to each other with back cushion 2 is fixed.

Referring to FIG. 3: in this embodiment, the control assembly 3 includes a motor 3a1, a first bevel gear 3a2, a second bevel gear 3a3, a worm 3a4, a worm wheel 3a5, a support rod 3a6, and a round rod 3a7;

the motor 3a1 is fixedly connected to the left side of the front end of the bottom belt buckle 9, the motor 3a1 is a servo motor, the type can be determined according to specific use conditions, the tail end of an output shaft of the motor 3a1 is fixedly connected with a first bevel gear 3a2, the right side of the lower portion of the first bevel gear 3a2 is meshed and connected with a second bevel gear 3a3, the right end of the second bevel gear 3a3 is fixedly connected with a worm 3a4, a worm wheel 3a5 is meshed and connected above the outer wall of the worm 3a4, the front end of an internal rotating shaft of the worm wheel 3a5 is fixedly connected with a support rod 3a6, the front side of the tail end of the support rod 3a6 is fixedly connected with a round rod 3a7, and the outer wall of the round rod 3a7 is connected with a handle 12 in a sliding manner;

through the cooperation between the motor 3a1, the bevel gear, the worm 3a4, the worm wheel 3a5, the round rod 3a7 and the handle 12, the motor 3a1 drives the worm 3a4 to rotate through the first bevel gear 3a2 and the second bevel gear 3a3, and then the worm 3a4 can drive the worm wheel 3a5 to rotate, when the worm wheel 3a5 drives the round rod 3a7 to rotate through the supporting rod 3a6, the round rod 3a7 can drive the handle 12 to rotate, so as to achieve the purpose of driving the handle to rotate, and during the second time, because of the self-locking capability between the worm wheel 3a5 and the worm 3a4, even when a child manually moves the handle 12, the rotation of the worm wheel 3a5 cannot be caused, the rotation process of the handle is effectively avoided not having any limit structure, so that the child is very easy to cause the handle to rotate because of mistake when taking, so that the protective belt is removed, and the problem of the protective function cannot be caused.

The working principle is as follows:

when the movable child car seat needs to be used, firstly, a user can assemble the whole structure according to the illustration in fig. 1, after the assembly is completed, the user can install the whole structure at the corresponding position of the vehicle by using the insertion hole at the seat cushion 7, since the insertion hole is completely penetrated, the whole structure can be transversely movably adjusted by the installation structure at the insertion hole, then, the child sits at the seat cushion 7, then the bottom belt 8 and the latch 13 are drawn out between the two legs, then the shoulder belt 4 and the side belt 11 are drawn out and are sequentially fixed at the buckle belt 13 by the latch, so as to completely fix the child at the seat, when the latch needs to be released, the latch can be released by rotating the handle 12 (not including the bottom belt latch 9), however, when the traditional child seat needs to release the connection of a plurality of protection belts, the release can be realized by mostly just directly moving the handle, however, since there is no restriction structure in the rotation process of the handle, it is very easy for a child to release the protection belt due to the rotation of the handle caused by a mistake collision when the child sits on the seat, and the protection belt cannot be protected, therefore, the control assembly 3 is designed, when the handle 12 needs to be rotated, the user can start the motor 3a1, so that the motor 3a1 drives the worm 3a4 to rotate through the first bevel gear 3a2 and the second bevel gear 3a3, and then the worm 3a4 can drive the worm wheel 3a5 to rotate, so that when the worm wheel 3a5 drives the round rod 3a7 to rotate through the supporting rod 3a6, the round rod 3a7 can drive the handle 12 to rotate, thereby achieving the purpose of driving the rotation, and during the second time, because there is a self-locking capability between the worm wheel 3a5 and the worm 3a4, even if the child manually moves the handle 12, the rotation of the worm wheel 3a5 cannot be caused, thereby effectively avoiding that there is no restriction structure in the rotation process of the handle, the problem that the protective belt is released due to the fact that the handle is easy to rotate caused by mistaken collision when a child sits on the protective belt is caused, and the protective function cannot be achieved.

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
