A kind of bindiny mechanism at novel electric tricycle back door and side door
The utility model relates to Platform for tricycle handle field, specifically a kind of novel electric tricycle back door and side door
In daily life, the use of electro-tricycle is very extensive, is mainly used for short distance and transports some sundries.Existing electricity
The side door of dynamic tricycle is traditionally arranged to be fixation and fail to open, or installs sliding door on side door to open side door, back door one
As only fixed with simple bolt, can only be turned over downwards, such side door can not be accomplished to fully open, back door be folded to ground again nothing
Any effect.The side door of some electro-tricycles can fully open, but the structure used is very complicated, and power resources are mostly
With motor, atmospheric pressure pole etc, involves great expense and structure is complicated leads to high failure rate.We need a kind of structure simple, function
The side door and back door structure of electro-tricycle as much as possible.

The technical solution of the patent is explained in further detail With reference to embodiment.
Please refer to Fig. 1-3, a kind of bindiny mechanism at novel electric tricycle back door and side door, including the first side plate 1, second
Side plate 2, third side plate 3, support frame 4, big fixed pulley 5, small fixed pulley 6, back door 11 and Fixed latches 21, due to compartment or so two
The side door structure of side is consistent and opposite in mirror image, therefore following narration only describes the structure of left side side door, and reader can basis
The structure of right side side door is deduced to the description of left side side door；The upper end of first side plate 1 is hinged on the edge on compartment top,
The lower end of first side plate 1 and the upper end of the second side plate 2 are hinged, and the second side plate 2 can be rotated mutually with the first side plate 1, second side
The left and right sides of 2 lower end of plate is equipped with universal wheel 9, and the lower end of the second side plate 2 is equipped with bending plate normal thereto, is evenly distributed on bending plate
Equipped with through-hole；Support frame as described above 4 is separately fixed at four angles of compartment bottom surface for four totally, and support frame 4 is equipped with sliding rail 41, sliding
Rail 41 cooperates universal wheel 9 to use, and the bottom end of the second side plate 2 can be moved up and down by universal wheel 9 along sliding rail 41, support frame 4
Bottom end be hinged with third side plate 3, the body cradle that the right end of third side plate 3 is overhanging with 4 bottom end of support frame is connected, third side plate 3
Left end be that free end can be equipped with protrusion around hinged rotation, compartment bottom surface near body cradle, protrusion is arranged in third side plate 3
Make at most 90 ° of the rotation of third side plate 3 on the path of rotation, the left end of third side plate 3 is equipped with bending plate normal thereto, bending plate
On be laid with through-hole, the bending plate on third side plate 3 it is corresponding with the bending plate on the second side plate 2 installation, the through-hole pair of the two
Qi Bingyong Fixed latches 21 connect, and are fixedly connected with the second side plate 2 with third side plate 3, the first side plate 1, the second side plate 2 and the
Three side plates 3 are sequentially connected from top to bottom, and three forms the side door in compartment；First side plate 1 is equipped with rope hook 10, and rope hook 10 is solid
It is scheduled on the first side plate 1, is connected with cord on rope hook 10, the rotation of the first side plate 1 is pulled by cord；The big fixed pulley 5 tilts
The outside of compartment roof plate is set, small fixed pulley 6 is equipped on the inside of compartment roof plate, big fixed pulley 5 and small fixed pulley 6 are all four
And be all distributed at four angles of floor compartment, corresponding peace turns between any two for big fixed pulley 5 and small fixed pulley 6, cord one end system
On rope hook 10, the other end is equipped with pull ring 7, support successively around excessive fixed pulley 5 and small fixed pulley 6 at the other end of cord
Frame 4 is equipped with buckle 8, and buckle 8 is a reclinate thin bar, buckles 8 installation site and the position consistency of pull ring 7, draws
Ring 7 can cover on buckle 8.
As shown in figure 4, the left and right sides of 2 lower end of the second side plate all cuts a part, it is equipped in the gap reserved
Universal wheel 9, universal wheel 9 can move up and down under the premise of not influencing the rotation of the second side plate 2 along sliding rail 41, and universal wheel 9 can band
The lower end edge sliding rail 41 of the second side plate 2 move up and down, the bottom end of the second side plate 2 is equipped with bending plate normal thereto, bending plate
It is equipped with through-hole, through-hole is equipped with bolt, and bolt is used to fix the mutual alignment of the second side plate 2 and third side plate 3.
As it can be seen in figures 5 and 6, the back door 11 is mounted on the rear side in compartment, back door 11 is fixed on compartment by bolt, after
It is laid with fixing axle 112 on door 11, fixing axle 112 is fixed on the middle position at back door 11, and every fixing axle 112 is designed with
Steel pipe socket 111, steel pipe socket 111 are directly interspersed in fixing axle 112, are not fixedly connected, and every steel pipe socket 111 is mutually contradictory
And it can arbitrarily be rotated around fixing axle 112.
The working principle of the utility model is: first extracting the second side plate 2 and third side when needing to transport using tricycle
Third side plate 3 is rotated outwardly to level, support of the third side plate 3 due to compartment bottom surface by the Fixed latches 21 of 3 junction of plate
It can keep horizontal, pull downward on pull ring 7 later, pull ring 7 will pull cord and pull first along small fixed pulley 6 and big fixed pulley 5
First side plate 1 can be pulled to by vertical state close to horizontality by the rope hook 10 on side plate 1,10 under tension of rope hook, while the
The rotation of side plate 1 will drive the rotation of the second side plate 2, and the universal wheel 9 of 2 lower end of the second side plate can be along sliding rail 41 to moving up
Dynamic, so that the second side plate 2 is also kept close to horizontality, at this moment compartment side door, which is opened, is completed, and will be pulled downward on 7 sets of rear pull ring and be existed
On buckle 8, make cord that tensioning state be kept to provide pulling force to be continuously the first side plate 1；It similarly, will after tricycle charges
Pull ring 7 is removed from buckle 8, and cord, which no longer provides pulling force, can fall after rise to rope hook 10, the first side plate 1 and the second side plate 2 to vertical
State, while rotation third side plate 3 is to vertical and connect with Fixed latches 21 with the second side plate 2 manually, at this moment, side door closes completely
When needing to use the back door 11 in compartment, the bolt extracted on back door 11 turns to touching around body cradle by back door 11 is natural
Ground is touched, it, can when article needs as early as possible from vehicle loading and unloading since the rotation change sliding friction of steel pipe socket 111 is rolling friction
Directly to slide into ground by back door 11 along steel pipe socket 111, while can also be by article along steel pipe socket when heavier article feeding
111 push to vehicle from ground.
