Description

Vehicle frame folding mechanism and use its perambulator

One, technical field

The utility model relates to the child's bicycle technical field, particularly a kind of vehicle frame folding structure and the child's tricycle of using it.

Two, background technology

Existing child's tricycle vehicle frame is front vehicle frame and back vehicle frame weld together.This structure is from the packing aspect, and it is bigger that three-wheel vehicle takies volume, can waste packaging space.Manufacturer is in order to reduce the volume of packing shipment, with the vehicle body frame knocked down packing; And the customer also will install in use in person, has all brought inconvenience for maker and customer.On the other hand, also be unfavorable for the customer when not using, it is accommodated in a less space.In becoming person bicycle, the vehicle frame folding structure is arranged, its foldable structure is to use pin shaft structure usually, and the lorizontal folding front and back wheel of bicycle that makes stacks.And child's tricycle need adopt longitudinal folding mode that front-wheel is folded near two trailing wheels downwards.So the foldable structure of one-tenth person bicycle also is not suitable for being grafted directly on the child's tricycle.

Three, summary of the invention

In order to solve above technical matters, the utility model provides a kind of vehicle frame folding mechanism, and the front-wheel of child's tricycle can be folded near two trailing wheels, and the packing of being convenient to dispatch from the factory also is convenient to the customer it is accommodated in less space.

The technical scheme of the utility model is: between the front vehicle frame of child's tricycle and back vehicle frame, fold mechanism is set; There is Foldble disk the end of front and back vehicle frame; Folding price fixing relative about two is arranged on the front frame head, a pair of centrosymmetric pin-and-hole is arranged on the right folding price fixing; There is a slice to fold Moving plate on the back vehicle frame head, inserts between two folding price fixings, on the folding Moving plate at least two pairs of centrosymmetric pin-and-holes are arranged; Every pair of pin-and-hole on the folding Moving plate can be respectively with folding price fixing on pin-and-hole align.There is axis hole at folding price fixing, folding Moving plate center.The finger setting assembly comprises the bearing pin that passes folding price fixing and folding Moving plate axis hole, is enclosed within the spring on bearing pin one end, with bearing pin other end bonded assembly pin plate, a pair of locating dowel pin that cooperates with pin-and-hole is arranged on the pin plate.The end that bearing pin is with spring constitutes button simultaneously.

Folding price fixing of the utility model and folding Moving plate can exchange front and back, and promptly folding price fixing is contained on the vehicle frame of back, and folding Moving plate is contained on the front vehicle frame; Two folding price fixings also can right and left mutually changing, promptly in the two folding price fixings one of the band pin-and-hole be contained in the left side.

Under the effect of spring force, the locating dowel pin pin is in a pair of pin-and-hole of pin-and-hole that folds price fixing and folding Moving plate, and front vehicle frame is fixed with the position of back vehicle frame; Press lower bearing pin; Drive pin plate and locating dowel pin and outwards move, locating dowel pin is deviate from from the pin-and-hole of folding Moving plate, and rotation back vehicle frame makes folding Moving plate rotate around bearing pin; To another during to pin-and-hole and alignment; Unclamp bearing pin, then locating dowel pin springs into this to pin-and-hole, and front vehicle frame and back vehicle frame are in this another stationkeeping.Realize opening of front and back vehicle frame and folding with the method.

As preferred version, adopt screw to connect between bearing pin and the pin plate, adopt screw to be connected between locating dowel pin and the pin plate.

As preferred version, the length of locating dowel pin and right folding the price fixing folding price fixing of pin-and-hole (promptly with) and the thickness sum of folding Moving plate equate that promptly locating dowel pin just can run through two pairs of pin-and-holes of alignment.

As preferred version, the movable distance of bearing pin in axis hole is the thickness of folding Moving plate, and when promptly pressing lower bearing pin, locating dowel pin just can break away from the pin-and-hole of folding Moving plate, and still in the pin-and-hole of folding price fixing.

As preferred version, be with on spring one termination at bearing pin a button cap is set.

As preferred version, protective cover is set in the outside of Foldble disk.Comprise left front lid (being the folding price fixing lid of button one side), be screwed on the left folding price fixing that its lower edge flushes with the interior edge of left folding price fixing, and the through hole of being convenient to push bearing pin is arranged in the middle of the top; Right front lid (being the folding price fixing lid of pin plate one side) is screwed on the right folding price fixing, and the interior edge of right folding price fixing flushes under its lower edge; Bonnet (promptly folding Moving plate lid) is screwed on back vehicle frame (a sidecar frame that promptly has folding Moving plate), and its front end is a ring, and the periphery that folds price fixing is wrapped in wherein.

This foldable structure is with the advantage of the child's tricycle of using this fold mechanism:

When shipment is packed, directly can vehicle frame folding be got up, the user directly opens and uses vehicle frame in use.Stability Analysis of Structures, folding volume is little, easy to use, and cost is low.
