Description

The vehicle frame of electric cycle

Technical field

The utility model is a kind of electric cycle, particularly relates to a kind of vehicle frame of the electric cycle that is formed by forward and backward car body winding.

Background technology

Electric cycle is a kind ofly mainly to be that an electrical equipment is installed on the vehicle frame, and at this bottom of frame roller to be installed that available personnel control driving with instead of walking at the old and the weak or the designed walking-replacing tool of individuals with disabilities.Because the volume of this vehicle frame is bigger, for the ease of making and carrying, manufacturer can make forward and backward two independent car bodies earlier usually, then the more mutual winding of car body is become a vehicle frame.Had at present the quite multiple lapping device that is used for the forward and backward car body of winding on the market, and this is novel just at the vehicle frame that a kind of lapped configuration innovation is provided.

The utility model content

Main purpose of the present utility model is to be to provide a kind of vehicle frame of constructing innovation and all simply easy electric cycle of assembly and disassembly.

The vehicle frame of a kind of electric cycle of the present utility model comprises: one first car body, one second car body, and a lapping device that is used for first and second car body of winding.This first car body has a cantilever that extends forward.This second car body has the mast of a corresponding position in cantilever the place ahead of this first car body.This lapping device comprises that one is installed in the projection of the front end top side of this cantilever, and one be fixed in this mast rear side and removably the elasticity clip in the clip unit of projection.

Be elaborated below by most preferred embodiment and accompanying drawing vehicle frame to electric cycle of the present utility model, in the accompanying drawing:

Fig. 1 is a part of three-dimensional exploded view of a preferred embodiment of this later-model electric cycle;

Fig. 2 is a three-dimensional exploded view of a clip unit of this preferred embodiment, and shows the amplification External view of a projection;

Fig. 3 is a part of cross-sectional schematic of this preferred embodiment, and the state that a front vehicle body and an aftercarriage are overlapped mutually with an angle is described;

Fig. 4 is a view that is similar to Fig. 3, and the state of this forward and backward car body clip location is described;

Fig. 5 is a three-dimensional winding figure of this preferred embodiment.

The specific embodiment

As Fig. 1 and shown in Figure 2, the preferred embodiment of this novel vehicle frame is mounted on the electric cycle, and comprises one first car body 1, second car body 2 in this first car body, 1 the place ahead, and a lapping device 3 that is used for first and second car body 1,2 of winding.First and second car body 1,2 is respectively back, front vehicle body in the present embodiment, also can make first and second car body 1,2 be inverted certainly in design, and become forward and backward car body respectively, in this explanation no longer in addition.And, because other structures of electric cycle are not this later-model creation emphasis, so no longer describe in detail at this.

This first car body 1 is to be formed by plural rod member winding solid welding, and has long first side lever 11 to extension about, reaches one by horizontally extending again cantilever 12 on first side lever, 11 mediads forward.

This second car body 2 also is to be formed by plural rod member winding solid welding, and have about one long to second side lever 21 that extends, an and mast 22 that uprightly is fixed in these second side lever, 21 central authorities.These mast 22 corresponding positions are in cantilever 12 the place aheads of this first car body 1.

This lapping device 3 is to be used for removably with first and second car body 1,2 windings together, and comprise a board 31, two that is installed in the front side below of first side lever 11 respectively from the left and right two ends of board 31 the upwards upright end plate that extends 32, two at intervals the upwards upright hook plate that extends 33, in front side of self-supporting plate 31 be located at second side lever, 21 rear sides at interval and the bar 34, of taking that should board 31 be convexly equipped with projection 35 in the front end top side of this cantilever 12, an and clip unit 36 that is fixed in the rear side of this mast 22.

This projection 35 has the direct reach face 351 of an orthostatic position at rear side, reaches one in the front side and towards front lower place bevelled oblique top face 352.This clip unit 36 be removably the elasticity clip in projection 35, and have one and be fixed in hollow shell block 361, on this mast 22 and be limited in fixture block 362, in the shell block 361 is connected and protrudes upward shell block 361 with fixture block 362 pull bar 363, and one is installed in the shell block 361 and has the elastomeric elastic component 364 that fixture block 362 is ejected shell block 361 downwards.This fixture block 362 has a corresponding oblique surface 365 that cooperates this oblique top face 352.

This shell block 361 is the L type base plates 366 that are fixed on this mast 22 by in the present embodiment, reaches a lid and puts 367 the windings formations of U type cover plate that are fixed on this base plate 366, also can have other to implement aspect certainly in design.And this elastic component 364 is a compression spring, be set on the pull bar 363 and contact 362 of base plate 366 and fixture blocks.In addition, this shell block 361 also has one and is formed on the cover plate 367 and the long up and down long slot bore 368 to extension, and this clip unit 36 also has the locating part 369 that stretches into this long slot bore 368 and be fixed in fixture block 362, see through locating part 369 and be limited in design in the long slot bore 368, can be in order to the distance of relative restriction fixture block 362 telescopic movings.

Consult Fig. 1 and Fig. 3, in group frame first, two car bodies 1,2 o'clock, assembler must be earlier with first, two car bodies 1,2 sides adjacent slight inclination is raised an angle, order is taken bar 34 correspondences and is put into hook plate 33 backward, 32 of first side lever 11 and end plates, and make cantilever 12 shift near mast 22 forward, allow projection 35 correspondences rely on the fixture block 362 of clip unit 36, then just can be with first, two car bodies 1,2 put down, because this moment cantilever 12 and mast 22 meeting swings in opposite directions, make projection 35 move forward contact fixture block 362, and allow oblique top face 352 move along oblique surface 365, can make fixture block 362 be subjected to contact simultaneously and automatically in the retraction shell block 362 and compress elastic component 364, as Fig. 4 and shown in Figure 5, when projection 35 continues to move forward when crossing fixture block 362 and supporting to mast 22, fixture block 362 just can protrude downwards by the reseting elasticity of elastic component 364, be blocked in the face that directes reach 351 rears of projection 35, and the position is above cantilever 12, in order to clip locating convex block 35, simultaneously, this take bar 34 also can corresponding lapping on this board 31, make that taking bar 34 is confined spacing at hook plate 33, first side lever 11,31 of end plate 32 and boards can increase by two car bodies 1,2 winding steadiness.

When dismounting, as long as pulling pull bar 363 drives in the fixture block 362 retraction shell blocks 361, break away from the position of clip projection 35, and raise second car body, 2 rear sides slightly, to take bar 34 and upwards move away from hook plate 33 and end plate 32 more forward, just first and second car body 1,2 can be separated decomposition.

As shown in the above description, this is novel to be to be the vehicle frame of the electric cycle of a structure innovation in design, has assembling and dismantle to be easy to effect, can reach this later-model purpose really.
