Abstract
A foldable and portable self-rescue trailer for electric bicycles and motorcycles of the utility model belongs to a self-rescue product solving the problem that the electric bicycles and the motorcycles are hard to push when having a flat tire. The trailer adopts a hinge connection, and is foldable and steerable, and gravity-induced self-locking technology is adopted. Based on the prior art, double universal wheels are used for guiding at the trailer head, so as to enable the electric bicycles and the motorcycles to make turns (a left-right parallel turning angle of the double universal wheels can reach 45 DEG, and a minimum turning radius can reach 550 mm) at will when being pushed to turn during self-rescuing. Because a head board of the trailer body has a gradient, a groove-shaped design is adopted, and the double universal wheels provides supporting and guiding for the trailer, the trailer body is more firm, the trailer does not get turned over when going forward or making turns, and self-rescuing efficiency is raised. The trailer of the utility model is compact in design and structure, small in size, foldable after being disassembled and convenient to carry, and is a must-have product for users of electric bicycles and motorcycles during traveling.
Description
Technical field
The utility model trailer of saving oneself adopts gemel connection, folds, can turn to, be subjected to the natural gravity can be from lock technology.
Background technology
It is not portable that traditional trailer of saving oneself has, though have adopt after the folding trailer-load Shortcomings on turn to, turn alerting ability and reliability; Some trailers Shortcomings on comfort feature and the practicality when loading and unloading fault tire.The utility model trailer headstock of saving oneself adopts two cardan wheels guiding, can arbitrarily turn when saving oneself, and reliable and stable, vehicle body adopts the gravity self-locking technology, and is also collapsible, easy to carry more convenient and practical.
The utility model content
The utility model trailer is for above-mentioned the deficiencies in the prior art, and the technical scheme of taking is:
A kind of electronic, portable trailer of saving oneself of Foldable motorcycle consists of the trailer main body by groove front apron, sector grooves base plate, globular universal wheel, directed carrying roller, hinge.
Headstock two globular universal wheels connect the guiding of can turning simultaneously by connecting rod, and the plane gravitate can form self-locking state on vehicle body groove front apron bottom two groove side angles and the sector grooves base plate.
Headstock two globular universal wheel carrying surfaces are connected with Type of Welding with baseplane, groove front apron upper end.
Vehicle body groove bottom surface, front apron lower end and sector grooves base plate bottom surface are by gemel connection.
The beneficial effect of the technical scheme that the enforcement of the utility model trailer provides is:
1, the headstock globular universal wheel adopts two-wheel parallel steer technology (two-wheel left and right sides parallel steer angle can reach greatly 45 °, and the turn radius I reaches 550mm), and is reliable and stable, not prone to tip over when trailer is turned.
The length of grade of the spherical two determined trailer front aproies of cardan wheel diameter dimension of the headstock that 2, calculates according to engineering mechanics, applicable difference is electronic, the diameter dimension of motor cycle tire, the trailer headstock is convenient to guiding, the power of reducing friction, so that battery-driven car, the motor bike easy ditch of crossing when trailer is carried out is more time saving and energy saving.
3, vehicle body groove base plate adopts the sector design, and applicable difference is electronic, the thickness size of motor cycle tire.
4, vehicle body is gone out easy to carry by folding mode.It is the indispensable part that battery-driven car, used in tyre explosion of motorcycle are saved oneself.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model using method is done to describe in further detail:
In exemplifying embodiment shown in Figure 1, vehicle body groove front apron (1) adopts the bending design to make the groove ramped shaped, and groove front apron (1) headstock bottom surface and spherical two cardan wheel (3) carrying surfaces are by being welded to connect.Can prevent electronic, bike wheel landing.
In exemplifying embodiment shown in Figure 2, headstock two globular universal wheels (3) rotational plane centre-drilling hole, carrying out rivet (8) by the boring of connecting rod (5) two ends again connects, make two-wheeled rotational angle direction consistent, two spherical two cardan wheels (3) connect the guiding of can turning simultaneously by connecting rod (5).Trailer carries out guide turning when carrying out turning with electronic, motor bike, so that the stability when turning is strengthened.
In exemplifying embodiment shown in Figure 3, when the angle of bottom, groove front apron (1) two groove side acts on the upper plane of sector grooves base plate (2), the plane forms the gradient on the groove, the angle of bottom, groove front apron (1) two groove side forms self-locking state simultaneously, can prevent electronic, overturning when motor bike is carried out forward.The fix screw (6) of groove front apron (1) trough rim side butterfly female (7) is embedded sector grooves base plate (2) trough rim side breach, and after butterfly female (7) was fastening, hinge (9) rotary expansion formed the trailer transit condition of saving oneself.Can by the solid wheel hole (10) that ties for subsequent use wheel be fixed with rope when crossing relatively more bumpy road surface, can play the haul effect of better saving oneself.
In exemplifying embodiment shown in Figure 4, loosening butterfly female (7) after the trailer unloading, groove front apron (1) two globular universal wheel (3) is relative folding with two directed load-supporting wheel (4), and trailer forms collapsed shape, and that folding trailer can be put into is electronic, Back-up box for motorcycle or front basket carry.
Claims (3)
1. electronic, portable trailer of saving oneself of Foldable motorcycle, consist of the trailer main body by groove front apron (1), sector grooves base plate (2), globular universal wheel (3), directed carrying roller (4), hinge (9), it is characterized in that: headstock two globular universal wheels (3) connect the guiding of can turning simultaneously by connecting rod (5), and the upper plane of vehicle body groove front apron (1) bottom two groove side angles and sector grooves base plate (2) gravitate can form self-locking state.
