At present the fold mechanism of Foldable electric vehicle on the market or Segway Human Transporter there are it is complicated, involve great expense, The problems such as stability and poor folding property.

Utility model content

To solve the problems, such as described in background technology, the utility model offer one kind is simple in structure, stability is good, safe to use Electric car fold mechanism.

The specific technical solution of the utility model is as follows：

A kind of fold mechanism of electric car including link block, sits pipe and seat tube socket, drawing pin and trailing wheel pipe and trailing wheel tube socket, It is characterized in that：Link block, seat tube socket, trailing wheel tube socket are linked together by axis pin, and M6 countersunk head screws are locked at axis pin both ends；It sits Pipe sleeve is screwed on the cylindrical tail portion of tube socket is sat；Trailing wheel pipe is connected on trailing wheel tube socket bottom, and is consolidated with screw It is fixed.

The axis pin is divided into a fixed pin shaft and two active pin shafts, and the pin diameter is 8mm.Two active pin shafts fill In in two arcuate socket of link block, two arcuate sockets can play the role of /V when folding and expansion.

It is set on the seat tube socket there are two groove, described two grooves play the work of positioning and insurance in folding and expansion With.

The bottom lock for sitting tube socket is provided with and to locking screw corresponding first there are one to locking screw on link block Groove and the second groove when sitting tube socket folding, are stuck in the second groove lock screw, and after sitting tube socket expansion, lock screw is pressed in Play the role of positioning on first groove of link block.

Described to draw pin T-shaped, T-shaped cross bar is cylindrical shaft, and spring, T-shaped montant end set are cased on T-shaped montant There is ball, the cylindrical shaft of pin and spring is drawn to be mounted on and sit in tube socket, for cylindrical shaft through the hole for sitting tube socket, montant, which passes through, sits tube socket Cylindrical tail portion and the center for sitting pipe.

It is provided with the 3rd groove corresponding with the cylindrical pin and the 4th groove on trailing wheel tube socket, under unfolded state, Cylindrical pin is stuck in the 3rd groove, plays the role of positioning and insurance；Under folded state, cylindrical pin is stuck in the 4th groove.

The beneficial effects of the utility model：The utility model realizes a kind of energy and is convenient for the handle simply folded, after folding Handle can carry out a positioning, prevent its double swerve, improve the vehicle safety performance after folding, and can also prevent from carrying after folding It is collided in the process with other objects, the utility model passes through sliding folding sleeve, you can easily handle is folded, is grasped Make simple.

Specific embodiment

The technical issues of in order to solve the utility model, technical solution and advantageous effect are more clearly understood, below In conjunction with the embodiments, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only To explain the utility model, it is not used to limit the utility model.

It should be appreciated that in the description of the utility model, the orientation or position relationship of the instructions such as term "left", "right" To be based on orientation shown in the drawings or position relationship, being for only for ease of description the utility model rather than requiring this practicality new Type must be with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.

A kind of fold mechanism of electric car, as shown in Figure 1, fold mechanism is by a link block 1, a seat tube socket 2, one Trailing wheel tube socket 3, a drawing pin 4, a seat pipe 5, a trailing wheel pipe 6, the axis pin 7 of three diameter 8mm, six M6 countersunk head screws 8 Composition.

As shown in Fig. 2, link block 1, sitting tube socket 2,3 three of trailing wheel tube socket three diameters being respectively penetrated after fitting together M6 countersunk head screws 8 are locked at the axis pin 7 of 8mm, both ends.

Axis pin 7 is divided to a fixing axle and two movable axis, and two movable axis are loaded in two arc grooves of link block 1, two arcs Slot can play the role of /V when folding and expansion.

It sits there are two groove on tube socket 2, this two grooves are to fold and be unfolded to play the role of positioning and insurance.

The bottom lock of tube socket 2 is sat there are one to locking screw 201, connection is pressed in lock screw 201 after sitting tube socket 2 and being unfolded Play the role of positioning on first groove 101 of block 1, when pleated, lock screw is stuck in the second groove 102.

Draw pin 4 T-shaped, T-shaped cross bar is cylindrical shaft, and spring 401, T-shaped montant end set are cased on T-shaped montant There is ball, the cylindrical shaft of pin and spring 401 is drawn to be mounted on and sit in tube socket, through the hole for sitting tube socket, montant is passed through to sit and managed cylindrical shaft The cylindrical tail portion of seat and the center for sitting pipe.

As shown in figure 3, when using folding, first the ball sat behind pipe 5 is drawn to make drawing pin 4 and the 3rd on trailing wheel tube socket 3 Groove 301 separates, and then will sit pipe group again and carries upwards, at this time again folds up trailing wheel tube socket 3 and link block 1, then will sit pipe group It rolls over downwards, the effect after folding is as shown in Figure 3.

Fold mechanism upon deployment, first draws the ball sat behind pipe 5 to make drawing pin 4 and the 4th groove 302 on trailing wheel tube socket 3 Then separation will be sat pipe group and carried upwards, trailing wheel tube socket 3 and the expansion of link block 1 get up again at this time again, then downward by pipe group is sat First groove is pressed onto to spring into.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, therefore, only This is should be included in all any modification, equivalent and improvement that the utility model specification and drawings content is made etc. Within the protection domain of utility model.
