Utility model content
The utility model provides a kind of new folding baby car, by changing the linked manner of two quadric chains,
Reduce the manufacture difficulty and cost of vehicle frame.
A kind of folding baby car, including the two sub- vehicle frames being arranged symmetrically, the sub- vehicle frame include front wheel bar, rear wheel bar, helped
Hand lever, preceding push rod and rear push-rod, the rear wheel bar, preceding push rod, bar, rear push-rod are hinged the one or four company for constituting closed loop successively
Seat fix bar is hinged with linkage, the rear push-rod；Front rod and back link are provided between the front wheel bar and rear wheel bar,
The front wheel bar, rear wheel bar, back link and front rod are hinged the second quadric chain for constituting closed loop, two quadric chains successively
Between be provided with gangbar, the pin joint between described gangbar one end connection front rod and back link, the other end is cut with scissors with preceding push rod
Connect, the sliding sleeve being engaged with seat fix bar is further fixed in the middle part of gangbar.
The quadric chain of the closed loop refers to that four connecting rods join end to end to form closed loop configuration, because quadric chain is unstable
It is fixed, it can rotate and fold.
The seat fix bar is used for fixing seat, and one is cloth nested structure to seat, is set in seat fix bar.
The gangbar is made up of two opposite arc sections, and the sliding sleeve is located at the intersection of two circular arcs, two circular arc
The opposite protrusion direction for referring to arc section of section is different, and the arc section of top is towards rear projection, the arc section of lower section in the utility model
Towards front projection, when so folding；Angle between two arc section intersections and seat fix bar is acute angle so that gangbar is promoted
The power of sliding sleeve is consistent with linkage bearing of trend, is easy to operation.
Described seat fix bar one end is hinged with rear push-rod, and the other end is provided with the inverted sections that can be folded down.Turnover is set
Section can reduce the volume after vehicle frame folding,
The inside lateral bend of inverted sections, for coordinating cloth to cover seat.
Provided with foot-operated between the inside lateral bend in front wheel bar bottom, two front wheel bars, the compact sense of vehicle frame is improved, increase is beautiful
Sight degree.
U-shaped handrail, convenient use and setting locking releasing mechanism are provided between the bar.
Provided with reinforcement cross bar between two rear push-rods.
The rear wheel bar is T-bar, and preceding push rod and front wheel bar are hinged with T-bar two ends, during expansion, and preceding push rod and front-wheel are done
It is substantially on same straight line.
The front rod is the bow arched upward.
During expansion, rear push-rod is on same straight line with bar so that preceding push rod, rear push-rod, bar, rear wheel bar are big
One triangle of composition is caused, vehicle frame stability is improved.
Two four-link mechanisms of the utility model vehicle frame realize that linkage is folded by gangbar, when rear wheel bar and front wheel bar group
Into lower supporter be fully deployed when, front rod and back link are simultaneously needed not be on same straight line, because gangbar has pushing tow
Power, can allow front rod and back link haul rear wheel bar and front wheel bar toward inner side shrink there is provided extra support.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model folding baby car exhibition open state.
Fig. 2 is the structural representation of the utility model folding baby car intermediateness.
Fig. 3 is the structural representation of the utility model folding baby car folded state.
Embodiment
As shown in figure 1, a kind of body frame structure for automotive of folding baby car, including two sub- vehicle frames being arranged symmetrically, every sub- car
Frame has bar 1, preceding push rod 2, rear push-rod 3, front wheel bar 5, rear wheel bar 6, is set respectively in the bottom of front wheel bar 5 and rear wheel bar 6
There are front-wheel 11 and trailing wheel 12.Wherein, bar 1, preceding push rod 2, rear wheel bar 6, rear push-rod 3 are hinged successively constitutes the 1st of closed loop
Linkage.And front wheel bar 5, front rod 7, back link 8 and rear wheel bar 6 are hinged the second double leval jib machine for constituting closed loop successively
Structure, has gangbar 4 to realize that two quadric chains can link folding, between them.The one end of gangbar 4 is hinged preceding push rod,
The other end is hinged to the pin joint between front rod 7 and back link 8.
It is well known that quadric chain is unstable closed loop configuration, rotated to one of pin joint applying power, remaining
Pin joint can rotate, so as to realize folding.When the first quadric chain is folded, it can be driven by gangbar
Second quadric chain is also folded, and is then same action principle during expansion.
When deploying for vehicle frame, with stable enabling capabilities, rear wheel bar 6 is T-type structure, two of which end respectively with
Front wheel bar 5 and preceding push rod 2 are hinged, when front wheel bar 5 and preceding push rod 2 turn to and be substantially at same straight line, rear push-rod 3 and bar
During in same straight line, locked between preceding push rod 2 and bar 1, now vehicle frame is in the state being fully deployed.
Seat fix bar 9 is further fixed on rear push-rod 3, the one end of seat fix bar 9 is hinged with rear push-rod 3, and the other end has
The inverted sections that can be folded down, because seat fixation pole length is longer, if cannot fold, as shown in figure 3, can increase car
Length after frame folding, it is not readily portable.The inside lateral bend of inverted sections, with certain radian, is easy to place seat.
As depicted in figs. 1 and 2, gangbar 4 is S types, is made up of two opposite segmental arcs of protrusion direction, its middle and upper part
Segmental arc is raised to vehicle frame rear, and the segmental arc of bottom has and seat to projection in front of vehicle frame in the boundary position of two segmental arcs
The sliding sleeve 14 that chair fix bar is slidably matched, in vehicle frame folding, sliding sleeve 14 is along the forward slip of seat fix bar 9, moving direction
It is just consistent with the inclined direction in the center section of gangbar 4, therefore smooth realization can fold very much.
Front rod 7 is the bow arched upward upwards, can increase the space of bottom of frame, be easy to setting to hold thing column.After two
There is reinforcement cross bar 13 between push rod, improve the bonding strength of vehicle frame.The bottom of two front wheel bar 5 curves inwardly, between provided with foot-operated 10.
U-shaped handrail 15 is provided between the bar of two handrail 1.Release the lock device 16 of the present utility model is located at the middle part of U-shaped handrail 15, release the lock device
For existing structure, including release the lock button and brake cable, pressing release the lock button can be by brake cable, by bar 1 and preceding push rod 2
Between locking mechanism open, so as to realize release the lock.
During folding, the locking mechanism between bar 1 and preceding push rod 2 has already turned on, and is pressed downward the company of bar the 1, the 1st
Linkage is folded, while gangbar 4 pushes front rod 7 and the pin joint of back link 8 is moved down, the second quadric chain
Also fold, be located at the both sides of rear wheel bar 6 after folding respectively.During expansion, then pull-up bar 1, the first double leval jib are only needed to
Simultaneously, the second quadric chain also deploys mechanism deploying, is locked between bar 1 and preceding push rod 2.
