Abstract
The utility model provides an electric vehicle wheel-rim, comprising a socket bottom which is arranged on the outside of the wheel-rim and used for taking up a wheel, two bar clasp wall parts and two bar clasp blocks which are extended from the two front ends of the two bar clasp wall parts in an opposite direction and used for holding the wheel. The joints between the socket bottom and the two bar clasp wall parts are respectively provided with two arc parts formed in one along the inner side of the wheel-rim in an opposite direction and an arc handover part connecting the two arc parts. An airspace is formed by the two arc parts and the socket bottom. Because the airspace is formed among the socket bottom, the two bar clasp wall parts and the two arc parts, the intensity, the force of impact and the compressive resistance of the wheel-rim are enhanced. The wheel can not deform even if the wheel is broken and leaks air. Thus the utility model provides the electric vehicle wheel-rim which can enhance strength and have force of impact and compressive resistance.
Description
Technical field
The utility model relates to a kind of wheel rim for bicycle and electric, particularly relates to a kind of wheel rim for bicycle and electric that increases wheel rim bearing strength and impulsive force and compressive resistance.
Technical background
Common wheel rim for bicycle and electric is commonly called as aluminium circle (as shown in Figure 1), and its inboard connection is supported spoke.Tire is accepted in the outside, connects the shape that supports spoke one side and is oblate arc, and the outside is for two clip wall portions and by this two clips wall portion front end clip piece that extend in opposite directions, that be used to stop tire.Because the complicated or collision of battery-driven car when operation road conditions, so the wheel rim width industry standard of battery-driven car is 30-31 centimetre usually, therefore be hit easily or resistance to compression after be out of shape.
Summary of the invention
In order to remedy above-mentioned defective, the utility model provides a kind of can increase self intensity, have impulsive force, compressive resistance, the later-model wheel rim for bicycle and electric of style.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of wheel rim for bicycle and electric, comprise the wheel rim outside accept tire accepting bottom, two clip wall portions and by this two clips wall portion front end clip piece that extend in opposite directions, that be used to stop tire, this is accepted the bottom and forms all-in-one-piece two curved portions and the arc junction that is connected this two curved portions respectively in opposite directions along the wheel rim inboard with the junction of this two clips wall portion, forms a spatial domain bottom being accepted by this two curved portions and this.
As further improvement of the utility model, the spacing between this two clips wall portion greater than this arc junction to this accept the bottom between distance.
Improve as of the present utility model another, the angle that is formed by this two curved portions is the obtuse angle.
As another improvement of the present utility model, by this two clips wall portion, accept and be convenient to the pin-and-hole territory of captiveing joint based on latch in the wheel rim two ends when bottom is formed for processing wheel rim respectively with the intersection of curved portions.
The beneficial effects of the utility model are: form a spatial domain between bottom, this two clips wall portion and this two curved portions because this is accepted, increased wheel rim intensity, impulsive force and compressive resistance, even during the broken threatened abortion gas of tire, also can not be out of shape; To the distance of accepting between the bottom, the angle that is formed by this two curved portions can the obtuse angle, under the prerequisite of guaranteeing wheel rim intensity, reduces the drag effects that is subjected to crosswind when wheel rim moves as far as possible like this greater than this two curved portions intersection for spacing between this two clips wall portion.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is common wheel rim for bicycle and electric section-drawing;
Fig. 2 is the wheel rim for bicycle and electric section-drawing of the utility model.
The specific embodiment
Embodiment: contrast Fig. 2 is further elaborated: a kind of wheel rim for bicycle and electric, comprise that accepting bottom 1, the two clip wall portions 2 of tire are accepted in the wheel rim outside and by this two clips wall portion front end clip piece 3 that extend in opposite directions, that be used to stop tire, this is accepted bottom 1 and forms all-in-one-piece two curved portions 4 and the arc junction 5 that is connected this two curved portions respectively in opposite directions along the wheel rim inboard with the junction of this two clips wall portion 2, forms a spatial domain 6 bottom being accepted by this two curved portions and this.
The spacing that this two clips wall portion is 2 can be designed to accept 1 the distance in bottom greater than this arc junction 5 to this, even to be designed to by the angle that this two curved portions 4 forms be the obtuse angle.By this two clips wall portion 2, accept and be convenient to the pin-and-hole territory of captiveing joint based on latch in the wheel rim two ends 7 when bottom 1 is formed for processing wheel rim respectively with the intersection of curved portions 4.
This wheel rim for bicycle and electric adopts aluminium alloy extrusions to process, at first be prepared into the section bar of section form wheel rim for bicycle and electric section-drawing shape as shown in Figure 2, utilize spheronizator to be processed into required wheel rim then, be fixedly connected into required wheel rim for bicycle and electric based on respective pin hole territory on latch and the wheel rim at last.
