Abstract
The utility model discloses a foldaway electric bicycle with two wheels, comprising a beam and a support device. The utility model is characterized in that the beam comprises a front part and a rear part, and a folder is arranged between the front part and the rear part section; the support device is fixedbeneath the rear part of the beam. The utility model can be in a stable upright state alone after folded.
Description
Technical field
The utility model relates to employed Electrical Bicycle in a kind of people's daily life, especially a kind of two-wheeled folding electric bicycle.
Background technology
A kind of two-wheeled folding electric bicycle on sale in the market, for realizing folder function, the crossbeam that connects two wheels constitutes by two sections, is provided with fold mechanism between two sections.During folded state, fold mechanism makes the leading portion of crossbeam be folded to back segment, and the axis of forward and backward like this wheel is substantially on same straight line.The two-wheeled folding electric bicycle is under folded state, owing to have only two wheels to support, so it can not be in stable erectility alone.
The utility model content
The technical problems to be solved in the utility model provides a kind of two-wheeled folding electric bicycle, and it can be in stable erectility alone after folding.
For solving the problems of the technologies described above, a kind of two-wheeled folding electric bicycle of the utility model, it contains crossbeam, this crossbeam constitutes by forward and backward two sections, be provided with fold mechanism between front and back, two sections, also contain bracing or strutting arrangement, this device is fixed on the below of crossbeam back segment.
Described bracing or strutting arrangement contains groove-shaped frame, bearing pin, baffle plate, strut bar and quick detach device, baffle plate is fixed on an end of groove-shaped frame, one end of strut bar is sleeved on the bearing pin, bearing pin is arranged on the top of groove-shaped frame and near the position baffle plate, the quick detach device is by sleeve pipe, shouldered pin, spring, handwheel constitutes, on the spring suit shouldered pin, shouldered pin is installed in the sleeve pipe, one end of sleeve pipe is fixed on the side plate of groove-shaped frame, one end of shouldered pin is installed in the through hole that the groove-shaped frame biside plate is provided with, below when this through hole is positioned at strut bar and is in the horizontal position, handwheel is arranged on the other end of shouldered pin.
The through hole that described groove-shaped frame biside plate is provided with, the axis distance in the horizontal direction of the center of this through hole and bearing pin 12 equal this through hole radius and strut bar 10 width half and.
The other end of described strut bar is provided with cardan wheel.
Owing to be provided with bracing or strutting arrangement below the back segment of two-wheeled folding electric bicycle crossbeam, under folded state, two wheels and bracing or strutting arrangement support simultaneously, so it can be in stable erectility alone after folding and can not topple over.During normal the use, can forward the strut bar of bracing or strutting arrangement to horizontal position, it be constrained in this position, therefore can not influence the cruising of vehicle by the shouldered pin of quick detach device.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.The structural representation of Fig. 2 when to be the utility model be in erectility alone after folding.Fig. 3 is the structure enlarged diagram of bracing or strutting arrangement of the present utility model.Fig. 4 is the A-A cutaway view of Fig. 3.Fig. 5 is that the B of Fig. 3 is to enlarged view.Fig. 6 is the structural representation of bracing or strutting arrangement when strut bar is in erectility shown in Figure 3.
1. front vehicle wheels among the figure, 2. crossbeam leading portion, 3. fold mechanism, 4. bracing or strutting arrangement, 5. crossbeam back segment, 6. rear wheel, 7. baffle plate, 8. shouldered pin, 9. groove-shaped frame, 10. strut bar, 11. cardan wheels, 12, bearing pin, 13. springs, 14. sleeve pipes, 15. handwheels.
The specific embodiment
Among Fig. 1, the crossbeam of the support of connection front vehicle wheel 1 and the support of rear wheel 6 is made of crossbeam leading portion 2 and crossbeam back segment 5.Between crossbeam leading portion 2 and crossbeam back segment 5, be provided with fold mechanism 3.Bracing or strutting arrangement 4 is fixed on the below of crossbeam back segment 5.Bracing or strutting arrangement 4 contains groove-shaped frame 9, bearing pin 12, baffle plate 7, strut bar 10 and quick detach device.Baffle plate 7 is fixed on an end of groove-shaped frame 9, and an end of strut bar 10 is sleeved on the bearing pin 12, and bearing pin 12 is arranged on the top and near the position baffle plate 7 of groove-shaped frame 9.The upper top of groove-shaped frame 9 can be fixed in the below of crossbeam back segment 5 by the mode of welding.In Fig. 4 and Fig. 5, the quick detach device is made of sleeve pipe 14, shouldered pin 8, spring 13, handwheel 15.On the spring 13 suit shouldered pins 8, shouldered pin 8 is installed in the sleeve pipe 14, on the side plate of the groove-shaped frame 9 that one end of sleeve pipe 14 is fixed on, one end of shouldered pin 8 is installed in the through hole that groove-shaped frame 9 biside plates are provided with, below when this through hole is positioned at strut bar 10 and is in the horizontal position, the axis distance in the horizontal direction of the center of this through hole and bearing pin 12 equal this through hole radius and strut bar 10 width half and.Handwheel 15 is arranged on the other end of shouldered pin 8.In order to be convenient to the push-and-pull walking under erectility alone more, the other end of strut bar 10 can be provided with cardan wheel 11.During normal the use, the handwheel 15 of quick detach device is pulled outwardly, and then the other end of shouldered pin 8 returns in the sleeve pipe 14, at this moment can forward strut bar 10 to horizontal position, unclamp handwheel 15, shouldered pin 8 is installed in the through hole that groove-shaped frame 9 biside plates are provided with under the effect of spring 13.Shouldered pin 8 constrains in this position with strut bar 10 like this, as shown in Figure 3.Under the folded state, the handwheel 15 of quick detach device is pulled outwardly, then the other end of shouldered pin 8 returns in the sleeve pipe 14, at this moment can forward strut bar 10 to stand up position, unclamps handwheel 15, and the other end of shouldered pin 8 returns to original position under the effect of spring 13.Shouldered pin 8 constrains in upright position with strut bar 10 like this, as Fig. 2 and shown in Figure 6.Because front vehicle wheel 1 and 6 of rear wheels and strut bar 10 support simultaneously, form gusseted, therefore under folded state, can uprightly and not can topple over alone.
