【Detailed ways】

Below in conjunction with accompanying drawing, the embodiment of the present utility model is described in detail.

The utility model is a novel folding stroller frame, which comprises a front wheel support rod 1, a rear wheel support rod 2, a linkage rod 3 and a push rod 4, and one end of the front wheel support rod 1 and the rear wheel support rod 2 are coaxially hinged on the One end of the linkage rod 3, when the car is folded, the front wheel strut 1, the rear wheel strut and the linkage rod 3 are folded together around their hinge points, and the other ends of the front wheel strut 1 and the rear wheel strut 2 are connected with a wheel Component 8, when unfolded and used, the front wheel strut 1 and the linkage rod 3 are unfolded around the hinge point to form a straight structure, and the rear wheel strut 2 forms an angle with the front wheel strut 1; the other end of the linkage rod 3 and the The middle part of the push rod 4 is hinged. When unfolded, the push rod 4 and the linkage rod 3 have a straight structure and partially overlap. The rod 4 and the linkage rod 3 are folded around their hinge points; the lower end of the push rod 4 is hinged with a support rod 5, the lower end of the support rod 5 is hinged with the middle part of the rear wheel strut 2, and the middle part of the support rod 5 is connected with the front wheel strut 1. The middle part is hinged with a seat backing plate 6. Through the action of the support rod 5 and the seat backing plate 6, the front wheel struts 1 and the rear wheel struts 2 can be moved towards each other or opened at the same time, so as to realize fast folding or folding of the car. It is unfolded and used, and the volume is minimized when the car is closed and folded, which is convenient for people to carry when going out.

In order to keep the folded state after the folding action of the car is completed, the bottom of the cushion plate 6 is provided with a car hook 7 for hooking the support rod 5 when the car is folded. The car hook 7 itself has certain elasticity and can Elastic deformation occurs, and the retractable coupler 7 is provided with a concave bayonet that matches the support rod 5, that is, after the folding action of the retractable vehicle is completed, one end of the support rod 5 is folded and attached to the bottom of the seat cushion plate 6, and acts on the retractable coupler. 7. Make it elastically deformed, and one end of the support rod 5 is snapped into the concave bayonet, as shown in Figure 10, at this time, the folded and closed state is locked.

In order to reduce the weight of the vehicle with fewer parts and components of the utility model, and also to save manufacturing and assembly costs, the push rod 4 and the support rod 5 described in the utility model all adopt an integrally formed rod in a U-shaped structure; and The front wheel struts 1 located on the left and right sides are connected to form a U-shaped structure, and can also be integrally formed.

In order to improve the comfort when pushing the cart, a handle can be installed on the U-shaped transition part of the push rod 4 accordingly.

When the support rod 5 adopts an integrally formed rod with a U-shaped structure, and when the folded and closed state is locked, the U-shaped transition part of the support rod 5 is folded and attached to the bottom of the seat cushion plate 6, and acts on the retractable hook 7, Make it elastically deformed, and the U-shaped transition portion of the support rod 5 snaps into the concave bayonet, that is, the locking action is completed.

When the front wheel strut 1 adopts an integrally formed rod member with a U-shaped structure, the two wheels 8 on the front side are installed on both sides of the transition part of the U-shaped structure accordingly.

When the car is folded as shown in Figure 10, the push rod 4 is turned up relative to the linkage rod 3 along its hinge point with the linkage rod 3, so that the hinged end of the linkage rod and the push rod 4 is folded downward, and the support rod 5 and the push rod 4 are folded downward. One end of the hinged end of the rod 4 is folded toward each other, and the other end is folded upward around the hinge point of the support rod 5 and the rear wheel strut 2. At this time, the hinged end of the seat plate 6 and the support rod 5 is under the action of the support rod Also fold down, and the hinged end of the seat plate 6 and the front wheel strut 1 then pulls the front wheel strut 1 to move closer to the rear wheel strut 2, and also makes the rear wheel strut 2 move towards the front wheel when the strut 5 is folded. Strut 1 draws close, and when push rod 4 folds and overlaps with linkage rod 3, then finishes the car folding action.

Since the front wheel strut 1 and the rear wheel strut 2 move closer to each other under the action of the support rod 5 during the folding process of the car, the utility model can quickly complete the folding action of the car.

As shown in Fig. 2 and Fig. 3, when the utility model needs to be deployed and used, first, the retracting coupler 7 is moved by hand to disengage the concave bayonet of the retracting coupler 7 from the U-shaped transition end of the support rod 5, and then move backward Pull the push rod 4, and the push rod 4 will make the support rod 5 and its hinged end turn upwards, and the other end of the support rod 5 will pull the rear wheel support rod 2 to open backward relative to the front wheel support rod 1, and the support rod 5 will pass through The hinge point between the middle part and the seat plate 6 makes the seat plate 6 turn over to be horizontal or close to the level, and the other hinged end of the seat plate 6 supports the front wheel strut 1 so that the front wheel strut 1 is opposite to the rear wheel. When the support rod 2 is opened, when the linkage rod 3 and the push rod 4 are in a straight connection structure, because one end of the linkage rod 3 is hinged with the middle part of the push rod 4, the linkage rod 3 and the push rod 4 are partially overlapped. At this time, the support rod 5. The stable triangular structure of the push rod 3 and the linkage rod 3 completes the unfolding action.

During the unfolding process of the utility model, since the front wheel strut 1 and the rear wheel strut 2 are opened for simultaneous back-to-back movement under the action of the support rod 5, the utility model can be quickly unfolded when it needs to be used, which is convenient for people use.

In addition, in order to maintain its unfolded state during use when deployed, a slot is provided at the end of the push rod 4, and a slot for inserting into the slot is provided in the middle of the linkage rod 3 to lock the push rod 4 and the linkage rod 3. The block in its expanded state.
