Description
Technical field
The utility model relates to the tire auxiliary mechanism of battery-driven car, is a kind of battery-driven car spare row wheel mechanism.
Background technology
Battery-driven car or claim Electrical Bicycle is meant the locomotive of electricity consumption masterpiece for driving, must not be according to the weight of national Specification Electrical Bicycle greater than 40 kilograms, but existing most of battery-driven cars are at 60 jin more than the kilogram.Because these battery-driven car quality are heavier, battery-driven car was passed comparatively inconvenience after trailing wheel was blown out, and for overcoming above-mentioned deficiency, some battery-driven cars must arise at the historic moment with tire device.As the patent No. ZL200820070493.6 that discloses in the Chinese patent literature, March 4 2009 Granted publication day, utility model title " a kind of battery-driven car spare tyre device "; This device comprises the Das Reserverad moulding bed and the axletree of spare tyre is installed that described Das Reserverad moulding bed comprises the auxiliary arc beam of left girder, right girder, left support beam, right support beam and fixing left and right girder; Described axletree middle part is arranged with axle sleeve, on the described axle sleeve bearing is installed, and on the described bearing spare tyre is installed, and the axial end of described spare tyre is equipped with the spare tyre flywheel, and described spare tyre flywheel is by chain interlock power chain wheel; One end of described left girder, left support beam and described right girder, right support beam is installed on described axletree two ends respectively.The starting of these spare tyres replaces the effect of trailing wheel work, but this spare tyre can not be completely fixed with vehicle frame and be one, can only install separately after blowing out, so it uses comparatively inconvenience.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of battery-driven car trailing wheel auxiliary battery-driven car spare tyre of advancing of blowing out that is mainly used in to this area, makes it solve existing like product and installs, uses the comparatively technical matters of inconvenience.Its objective is and be achieved through the following technical solutions.
A kind of battery-driven car spare row wheel mechanism, this mechanism comprises reserve wheel, mobile jib, second hinged place, secondary bar, the 4th hinged place, the reserve wheel is connected with the 4th hinged place by secondary bar, secondary bar is connected with second hinged place of mobile jib, one end of mobile jib is provided with the reserve wheel, and this mechanism is installed near the crotch of bottom of frame or trailing wheel, and the reserve wheel is small-sized road wheel, can pack up when not using, can fall during use.Its key points in design is that vehicle frame is fixed in described the 4th hinged place, is connected by the pivotally attached mode between mobile jib and the secondary bar, and the vertical dimension of mobile jib is greater than the height between vehicle frame and the ground.Drive mobile jib by secondary bar and rotate, pack up and fall thereby reserve wheel on the mobile jib is finished.Its structure mainly contains following dual mode:
Mobile jib between the described reserve wheel and first hinged place is provided with second hinged place, and the secondary bar between second hinged place and the 4th hinged place is provided with the 3rd hinged place, and vehicle frame is fixed in first hinged place.This mode is mainly utilized hinged principle, and the stroke that the reserve wheel is packed up and fallen is bigger, and the fixed form of mobile jib and secondary bar is comparatively convenient.
Mobile jib between described reserve wheel and the rotating shaft is provided with second hinged place, and second hinged place is connected with the 4th hinged place by secondary bar, and vehicle frame is fixed in second hinged place; Rotating shaft is arranged at support bracket fastened arc chute, and fixed support is fixed in vehicle frame.This mode is mainly utilized fan-shaped rotary principle, and the stroke that the reserve wheel is packed up and fallen is decided by the mobile jib length of second hinged place to the reserve wheel.
Be provided with the deflation spring between described mobile jib and the vehicle frame, tighten the location that spring is used for the mobile jib lifting position.
The auxiliary walking mechanism that the utility model belongs to battery-driven car after blowing out, it is reasonable in design, and is simple in structure, easy to use, and stability, safety are good, are applicable to battery-driven car moving after blowing out.
Description of drawings
Fig. 1 is embodiment one structural representation of the present utility model, and dotted line is the state that the reserve wheel is packed up among the figure.
Fig. 2 is embodiment two structural representations of the present utility model, and dotted line is the state that the reserve wheel is packed up among the figure, and arrow is a rotation direction.
Figure number and title: 1, reserve wheel, 2, mobile jib, 3, first hinged place, 4, second hinged place, the 5, the 3rd hinged place, 6, secondary bar, the 7, the 4th hinged place, 8, fixed support, 9, rotating shaft.
The specific embodiment
In conjunction with the accompanying drawings, the utility model is further described.Embodiment one as shown in Figure 1, the bottom of vehicle frame is fixed in the 4th hinged place 7 of this mechanism, and the 4th hinged place is connected with second hinged place 4 of mobile jib 2 by secondary bar 6, and secondary bar is divided into two sections by the 3rd hinged place 5.One end of mobile jib is connected with first hinged place 3, and the bottom of vehicle frame also is fixed in first hinged place; The other end of mobile jib is provided with reserve wheel 1, and the reserve wheel adopts the small-sized road wheel that has bearing.When the trailing wheel of battery-driven car was blown out, because storage battery, motor etc. concentrate on the rear portion center of gravity of battery-driven car than heavy parts, battery-driven car is difficult to be promoted.At this moment, the reserve of bottom of frame wheel is put down, the vertical dimension of mobile jib is greater than the distance between vehicle frame and the ground, and mobile jib, secondary bar, reserve wheel recede, and promote battery-driven car forward, and reserve wheel and front-wheel drive battery-driven car and move.
2 embodiment two as shown in the figure, the secondary bar of this mechanism omits the 3rd hinged place, mobile jib omits first hinged place, one end of mobile jib is connected and fixed support 8 by rotating shaft 9, vehicle frame is fixed in second hinged place of mobile jib, by the fan-shaped rotation of mobile jib, also can change the vertical distance between the reserve wheel and ground on the mobile jib, reach the same technique effect of the foregoing description one.
