Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment being further elaborated to the technical solution of the utility model.
Referring to the Folding trolley shown in Fig. 1, Fig. 2, which is included with deployed condition and the vehicle frame of folded state, located at vehicle frame
The wheel assembly of bottom, for vehicle frame is locked locking mechanism in the deployed state.Vehicle frame is included respectively positioned at the left and right sides
Side stand 100 and the stull component being connected between both sides side stand 100.
Side stand 100 per side includes front support rod 1, back stay 2, push rod 3, seat bar 4 and connecting rod 6, and front support rod 1 is from forward direction
Gradually updip extends afterwards, and the top of front support rod 1 is connected with the bottom phase pivot of push rod 3, and the bottom of front support rod 1 is provided with front-wheel 20；
Back stay 2 is vertically extending, and its underpart is provided with trailing wheel 30, and push rod 3 is slidably located at along the length bearing of trend of back stay 2
On back stay 2；Seat bar 4 extends along the longitudinal direction, and the back pivot of seat bar 4 is connected to the bottom of back stay 2, the front portion of seat bar 4
Can not only relatively rotate between front support rod 1 but also relative slidably can arrange；The one end of connecting rod 6 is pivotally connected on front support rod 1,
The other end of connecting rod 6 is pivotally connected in the top of back stay 2.
Specifically, it is referring to shown in Fig. 1, Fig. 2, pivotally connected on front support rod 1 to have the first sliding part 5,5 energy of the first sliding part
Enough length bearing of trends along seat bar 4 are slidably arranged on a bar 4, herein first sliding part 5 adopt slidably to cover
The sliding sleeve being located on a bar 4.It is fixedly provided with back stay 2 for providing the second sliding part 7 of 3 slide-and-guide of push rod, this
Two sliding parts 7 can be one or more, and push rod 3 can slide up and down to setting with respect to the second sliding part 7, after realizing relatively
Pole 2 slides up and down.Herein, the second sliding part 7 adopts the second sliding sleeve being slidably set on push rod 3, and second cunning
Set is provided with two, and the two second sliding sleeves are spaced apart and arranged on back stay 2, so as to provide length of the push rod 3 along back stay 2
With stable slide-and-guide, push rod 3 is passed the bottom after all second sliding sleeves 7 and is connected with the top phase pivot of front support rod 1 in direction
Connect.
The one end of connecting rod 6 is pivotally connected on front support rod 1 by first axle 11, and the first axle 11 is upper in front support rod 1
In the rear of the first sliding part 5；The other end of connecting rod 6 is pivotally connected in the top of back stay 2, also can be direct by which during setting
It is pivotally connected on the second sliding sleeve 7 at the top of back stay 2.
Referring to shown in each accompanying drawing, on the Folding trolley stull component can launch in left-right direction or folding be connected to both sides
Side stand 100 between, so when vehicle frame folding, folding just can drive the side stand of both sides to stull component in left-right direction
100 mutually draw close in left-right direction.
Specifically, on the vehicle frame, stull component includes bottom cross support component 8 and rear attached support component 9.Bottom cross support component 8
It is including intersecting and connecting and the two foundation struts 81 that extend along the longitudinal direction in infall phase pivot, equal per foundation strut 81
Arrange as follows：The front portion of bottom supporting rod 81 is rotationally connected to the front portion of the seat bar 4 of side by the first adaptor 82
On, the rear portion of the bottom supporting rod 81 is rotationally connected on the bottom of opposite side back stay 2 by the second adaptor 83.Wherein,
One adaptor 82 is present on bar 4 and is located at the front of the first sliding part 5, after the rear portion of seat bar 4 is pivotally connected in by the second axle 12
On pole 2, the second adaptor 83 is on back stay 2 positioned at the lower section of above-mentioned second axle 12.Attached support component 9 can be in left-right direction afterwards
Folding launches ground between the back stay 2 of both sides, adopt herein in the art conventional with lateral locking function
Attached support component.
When the vehicle frame is locked in deployed condition, as shown in figure 1, rear attached support component 9 launches in left-right direction and is supported on two
Between the back stay 2 of side, bottom cross support component 8 intersect launch and support the front portion of both sides seats bar 4 and back stay 2 bottom it
Between.On side stand 100 per side, 3 relative back stay 2 of push rod stretches out, and push rod 3 is prolonged approximately along same length direction with back stay 2
Stretch, triangular structure is formed between front support rod 1, connecting rod 6 and back stay 2, push rod 3, between seat bar 4, front support rod 1, back stay 2
Triangular structure is formed, this causes vehicle frame to have good stability in the deployed state.
When needing vehicle frame folding gets up, after locking mechanism is unlocked, referring to shown in Fig. 3, Fig. 4, along the side of arrow C
Then the push rod 3 of both sides is pressed downward so that push rod 3 is along back stay 2 by attached support component 9 in the direction of arrow A to after unlocking upwards
Length direction move downward and gradually mutually draw close with back stay 2；Push rod 3 drives the upper of front support rod 1 while moving downward
End is descending, and in the presence of connecting rod 6, the anterior and front-wheel 20 of front support rod 1 is increasingly towards upwards and backward push rod along arrow E directions
3 upsets；Under the drive of 3 flip-flop movement of relative push rod of front support rod 1, the first sliding part 5 along seat bar 4 length bearing of trend forward
Slide, i.e., the direction forward slip of arrow D along Fig. 3, while seat bar 4 is relative with the drive of the first sliding part 5 in front support rod 1
Back stay 2 overturns, i.e., the front portion of seat bar 4 is overturn with push rod 3 upwards and rearwardly towards back stay 2.In above process, seat
Drive the front portion of the bottom supporting rod 81 of both sides to move upwards and backward when bar 4 overturns so that the bottom supporting rod 81 of both sides relatively rotate and
Gradually draw in left-right direction, so that the side stand 100 of both sides is gradually drawn close in left-right direction, i.e., the arrow B along Fig. 3
Direction is gradually drawn close.
Finally, as shown in figure 5, on the side stand 100 of the same side, push rod 3 is mutually drawn close with back stay 2, front support rod 1 and seat bar
4 draw close the front side in back stay 2 with push rod 3；The side stand 100 of both sides is close together in left-right direction, and attached support component 9 is received afterwards
Between the side stand 100 of both sides, two foundation struts 81 of bottom cross support component 8 mutually draw in and draw close the front side of present bar 4 folding.
Body frame structure for automotive after folding is simply compact, takes up room also less, facilitates user to carry and storage.
Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalence changes made according to this utility model spirit or modification, should all cover protection domain of the present utility model it
It is interior.
