Abstract
The utility model relates to a conjoined combination speed adjustment and brake apparatus for the electric bicycle, the electric motorcycle and the electric tricycle. The conjoined combination speed adjustment and brake apparatus comprises a braking handle and a speed-regulating handle, wherein an arc groove is arranged out of an inserting hole of the braking handle, and one end of the arc groove is provided with an anti-return plate, an arc inserting grab is arranged out of a fixed inserting hole of the speed-regulating handle, and the end of the arc inserting grab is provided with an anti-return barb. When the utility model is assembled, the arc inserting grab of the fixed seat of the speed regulating handle is inserted in the arc groove of the braking handle, and rotated at a small angle, so the anti-return barb of the end of the arc inserting grab is locked by the anti-return plate of the arc groove, thereby being connected into a whole, finally the connected body of the braking handle and the speed-regulating handle are sleeved on the handlebar, and the braking handle is fastened, so the whole assembly can be finished. The assembly is much simpler than the prior art, because the speed-regulating handle is inserted on the braking handle for positioning, so the coaxiality and flexible movement of a spring-back component can be simply guaranteed.
Description
Technical field
The utility model relates to a kind of speed-regulating brake device of elec. vehicle, especially a kind of speed-regulating brake device that is applicable to Electrical Bicycle, battery-operated motor cycle, electro-tricycle.
Background technology
The elec. vehicles such as Electrical Bicycle that developed recently gets up have the advantage of environmental protection, therefore more and more are subjected to people's welcome.Applicant early sets foot in the research of this type of vehicle speed governing, brake gear, development has been proposed multinomial patent application.
Understand according to the applicant, the speed governing that existing elec. vehicle, especially Electrical Bicycle adopt, brake gear are made of two parts speed control crank and brake respectively, and are installed on the handlebar by fastener respectively.During assembling, at first with braking being enclosed within on the handlebar, be screwed, the permanent seat of suit speed-regulating handle bar is fixed on speed-regulating handle bar on the handlebar by the metallic sheath holding screw that is coated in the permanent seat again.The problem that said structure reflects in practice is that assembling is complicated, holding screw is easy to generate the assembling deflection, is difficult to guarantee speed control crank and brakes concentric, influences the resilience that resets of movement parts.
Summary of the invention
The purpose of this utility model is: propose a kind of easy to assembly, can guarantee right alignment, avoid the malfunctioning disjunctor combined speed regulating brake gear of movement parts resilience.
In order to reach above purpose, disjunctor combined speed regulating brake gear of the present utility model comprises brake handle and speed-regulating handle bar, and the inserting hole of wherein said brake handle is shaped on arc groove outward, and an end of described arc groove is shaped on retaining stopping piece; The permanent seat inserting hole of described speed-regulating handle bar is shaped on circular arc outward and inserts pawl, and the termination that described circular arc is inserted pawl is shaped on retaining barb.
During assembling, the circular arc of speed-regulating handle bar permanent seat is inserted in the arc groove of pawl insertion brake handle, then rotate a low-angle, the retaining barb that makes circular arc insert the pawl termination is blocked by the retaining stopping piece of arc groove, thereby be connected as a single entity, brake handle and the speed-regulating handle bar at last disjunctor combined are enclosed within on the handlebar, tighten up the brake handle, can finish a dress assembling.
Obviously, above fitting process is easier to be many than prior art, and because speed-regulating handle bar is inserted into brake last location, the motion of therefore easy assurance right alignment and resilience part freely.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the brake bar structure scheme drawing of the utility model embodiment one.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the speed-regulating handle bar structural representation of the utility model embodiment one.
Fig. 4 is the right elevation of Fig. 3.
The specific embodiment
Embodiment one
The brake of present embodiment disjunctor combined speed regulating brake gear is as shown in Figure 1 and Figure 2, and the polymorphic structure of top hollow is the position of hinge dress brake lever.The bottom will be for braking the inserting hole 1 that is sleeved on the handlebar, and the c-shaped clamping structure of this inserting hole can be with brake being clamped on the handlebar by the screw that passes screw hole 2.Inserting hole 1 periphery is shaped on the arc arc groove 3 in two places and place's waist shape arc groove 4 at interval, and half of arc arc groove 3 arc length is shaped on retaining stopping piece 5.
The permanent seat of present embodiment disjunctor combined speed regulating brake gear speed-regulating handle bar as shown in Figure 3, Figure 4, the corresponding brake of inserting hole 1 ' periphery is shaped on two place's circular arcs to the position of arc arc groove 3 and inserts pawl 3 ', and corresponding brake is shaped on place's circular arc locating dowel pin 4 ' to the position of waist shape arc groove 4.The arc length of the slotting pawl 3 ' of circular arc just in time equals half of arc arc groove 3 arc length, and the termination is shaped on retaining barb 5 '.
During assembling, two circular arcs of speed-regulating handle bar permanent seat are inserted pawl 3 ' to be inserted respectively in the corresponding groove of brake handle with locating dowel pin 4 ', rotate a low-angle again, the retaining barb 5 ' that makes two circular arcs insert pawl 3 ' termination is just in time blocked by the retaining stopping piece 5 of two arc grooves respectively, has promptly finished brake assembling with the disjunctor of speed-regulating handle bar.Then siamesed brake handle and speed-regulating handle bar are enclosed within on the handlebar, by screw lock brake handle, assembling finishes.
The present embodiment design is perfect, and will brake handle and speed-regulating handle bar organically combine cost economy.Facts have proved that above fitting process is simple and convenient, speed-regulating handle bar is good right alignment with brake, can guarantee the motion of resilience part freely.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
