The specific embodiment
In the following description, laterally be the left and right directions of three-wheel vehicle, i.e. the relative fore-and-aft direction (vertically) of three-wheel vehicle.Shown in Fig. 1-4, the child's tricycle of present embodiment has deployed condition (Fig. 1) and folded state (Fig. 3), because collapsible, its convenient transportation, cost are lower.Following mask body is set forth the structure of child's tricycle.
Child's tricycle mainly comprise vehicle frame, rotationally be arranged at the front-wheel 2 of front portion at the bottom of the vehicle frame, be arranged at the trailing wheel 3 at the rear portion, the end of vehicle frame both sides, the headstock 19 of wheel 2 tops rotationally, wherein vehicle frame further comprise the bottom be provided with the front fork 10 of front-wheel 2, with the rotatable mutually preceding standpipe 11 that is provided with of front fork 10, main support 12, along being horizontally installed on U-shaped carriage 20 on the main support 12, being positioned at the side stand 1 of main support 12 both sides and symmetrical setting.Described main support 12 is arranged between front-wheel 2 and the trailing wheel 3, and its leading section is captiveed joint with preceding standpipe 11, rearward end is captiveed joint with the hind axle of trailing wheel 3.Described side stand 1 is by main support 12 and carriage 20 together support, specifically comprise the basketry bar 13 that leading section and main support 12 are fixedly connected, the leading section of bottom and basketry bar 13 is by the first turning cylinder 8 bonded assembly front frame 14 that rotates, bottom and basketry bar 13 are by the second turning cylinder 9 bonded assembly after poppet 15 that rotates, the upper end of bottom and front frame 14 is by the 3rd turning cylinder 17 bonded assembly push rod 16 that rotates, the upper end of after poppet 15 rotates by the 4th turning cylinder 18 with the bottom of push rod 16 and is connected, so, push rod 16, front frame 14, after poppet 15 and basketry bar 13 constitute four-bar linkage.
For the convenience that is provided with, in this example, rivet is connected with push rod attaching parts 5 in the bottom of push rod 16, at the upper end of front frame 14 riveted joint front frame attaching parts 6, push rod attaching parts 5 rotates by described the 3rd turning cylinder 17 with front frame attaching parts 6 and is connected, and the upper end of after poppet 15 rotates by described the 4th turning cylinder 18 with push rod attaching parts 5 and is connected.
By above-mentioned four-bar linkage, can carry out folding operation to vehicle frame, as shown in Figure 2, clockwise direction rotating push-rod 16, front frame 14 and after poppet 15 will rotate counterclockwise around first turning cylinder 8 and second turning cylinder 9 respectively, when push rod 16 turned to horizontality, child's tricycle reached folded state completely.Decline to a great extent before the aspect ratio of the three-wheel vehicle after obviously, folding is folding.
The people of this area is appreciated that the normal use for three-wheel vehicle, one or more lockout mechanisms need be set so that vehicle frame can stably be in deployed condition.In this example, because the control vehicle frame folding is four-bar linkage, thereby a lockout mechanism is set between any two connecting rods gets final product.The utility model does not have specific limited to the structure of lockout mechanism, and the lockout mechanism of any this area routine all can be used in this example, but preferably has following structure:
As shown in Figure 4, lockout mechanism 4 comprise in push rod attaching parts 5 the bottom rivet bonded assembly dead bolt 40 that is connected back and push rod 16 with its screw, be opened in the opening 41 on the front frame attaching parts 6 and be arranged on dead bolt 40 and push rod attaching parts 5 between elastic component 42, elastic component 42 can be that spring or other have the parts of elastic force, rely on its elastic force, dead bolt 40 can remain in the opening 41 of front frame attaching parts 6, thereby make relative locking between push rod attaching parts 5 and the front frame attaching parts 6, and then make whole vehicle frame locking.
In addition, child's tricycle is folding for convenience, the release mechanism that lockout mechanism 4 is carried out release need be set, in this example, release mechanism is a handle 7, it is connected the back and is connected with push rod 16 rivets with push rod attaching parts 5 screws, and it is connected pulling handle 7 with dead bolt 40, can drive dead bolt 40 moves, make dead bolt 40 overcome the elastic force of elastic component 42, in opening 41, break away from, realize release.
The folding process of the child's tricycle of present embodiment is as follows:
Pull the handle 7 of moving three-wheel vehicle both sides, handle 3 drives dead bolt 40 and rearward moves, and elastic component 42 is compressed, the opening that dead bolt 40 breaks away from the front frame attaching parts 7, lockout mechanism 4 is unlocked, and the clockwise direction rotating push-rod 16 then, when it turns to horizontality, folding finishing.
The expansion process of the child's tricycle of present embodiment is as follows:
Holding push rod 16 upwards lifts, parallel motion, dead bolt 40 head inclined-planes are run into front frame attaching parts 7 and are squeezed and move inward, elastic component 42 compressions, when moving on to the opening 41 of front frame attaching parts 7, the stressed disappearance of dead bolt 40 heads, elastic component 42 advances dead bolt 40 in the openings 41 by elastic force and locatees.
Below in conjunction with the embodiments the utility model has been done detailed explanation, its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented, and can not limit protection domain of the present utility model with this.All equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
