Detailed Description

In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model discloses in, folding fixed knot constructs the setting on children's seat, and this children's seat sets up on electric bicycle.

As shown in fig. 1 to 6, the folding and fixing structure includes a steering shaft sleeve assembly 10, a rotary swing arm assembly 20, a positioning rod 30, a handle 40, a guiding elastic sheet 50, a spring 60, a snap spring 70, a fixing frame 80, a positioning groove 90 and a shock-absorbing limit pad 100.

The steering boss assembly 10 includes a steering shaft 11 and a boss 12. The shaft sleeve 12 is sleeved on the steering shaft 11.

The rotary swing arm assembly 20 includes a first rotary arm 21, a second rotary arm 22, and a connecting member 23. The first rotating arm 21 and the second rotating arm 22 are fixed to both ends of the steering shaft 11 by fixing screws 24, respectively. The first rotating arm 21 and the second rotating arm 22 rotate by driving the steering shaft 11, thereby performing a function of rotating around the shaft sleeve 12.

Both ends of the connecting member 23 are connected to the first rotating arm 21 and the second rotating arm 22, respectively. The connecting piece 23 has a hollow structure inside.

One end of the positioning rod 30 is fixedly connected with the handle 40, and the other end thereof penetrates through the connecting piece 23 to be in contact with the guiding elastic piece 50. The positioning rod 30 is provided with a fixing plate 31 penetrating the connecting member 23. The fixing plate 31 is provided on a side of the connecting member 23 adjacent to the handle 40.

The spring 60 is sleeved outside the positioning rod 30 and is located in the inner space of the connecting piece 23. One end of the spring 60 contacts with the inner wall of the connecting piece 23 near one surface of the fixing plate 31, and the other end is fixed with a clamp spring 70.

The fixing frame 80 includes a circular arc section and a right angle section. The circular arc segment is fixed on the shaft sleeve 12 around the shaft sleeve 12. The right-angle section is provided with a right-angle corner, and one end of the right-angle section is smoothly connected with the circular arc section.

The guiding elastic sheet 50 is closely attached to the outer surface of the arc section of the fixing frame 70.

The orientation groove 90 is provided on a circular arc section of the fixing frame 70. The guiding groove 90 contacts with one end of the guiding elastic sheet 80 far away from the right-angled section of the fixing frame 70.

The shock-absorbing position limiting pad 100 is disposed at a right angle of the right-angle section of the fixing frame 70. The shock-absorbing limit pad 100 is a TPU shock-absorbing limit pad.

The locking process of the folding and fixing structure is as follows: the handle 40 is pushed and slid, so that the positioning rod 30 moves in the direction of F1 in fig. 3, i.e., approaches the positioning groove 90 along the guide elastic piece 80. Because the guiding elastic sheet 80 is tightly attached to the arc section, the guiding elastic sheet 80 also has a certain radian, and therefore, in the moving process of approaching the positioning groove 90, the guiding elastic sheet 80 pushes against the positioning rod 30, so that the spring is in a compressed state; when moved to the position of the positioning groove 90, the positioning rod 30 falls into the positioning groove 90 in the direction of F3 in fig. 6 by the elastic force of the spring 60.

The unfolding process of the folding and fixing structure comprises the following steps: the handle 40 is pulled out of the positioning slot 90 in the direction F4 in fig. 6, and then the handle 40 is pulled away from the positioning slot 90 in the direction F2 in fig. 6, that is, along the guide spring 80, until the positioning rod 30 contacts the shock absorbing stopper 100.

According to the folding fixed knot of above-mentioned embodiment, when needs are accomodate foldingly, remove the handle and take the locating lever towards the direction of constant head tank along the direction shell fragment together, at this removal in-process, the locating lever is being pushed to the direction shell fragment for the spring is in compression state, and when the locating lever moved the constant head tank, the locating lever was pushed in the constant head tank under the spring action of spring, makes rotatory swing arm subassembly by the locking in this position department. When the folding structure needs to be opened, the positioning rod only needs to be pulled out from the positioning groove and moves towards the direction far away from the positioning groove along the guide elastic sheet. According to the folding fixing structure, the whole locking and unfolding processes are rapid and convenient, the cost of the whole folding fixing structure is low, and the user can realize the functions of folding locking and unfolding under the condition of not using other tools.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their full equivalents, the present application is intended to include such modifications and variations.
