Abstract
The invention discloses a brake crank, which comprises a pressing plate, a spring, a rivet, a handle, a buckle, a hollow rivet and a left bracket, wherein the spring is arranged between the lower part of the pressing plate and an accommodating cavity of the handle; a slot is formed on the buckle, and the buckle penetrates through the slot and is fixed on the handle through the rivet; a groove is formed in front of the left bracket and is engaged with a fastener at the front end of the pressing plate; the left bracket comprises a bracket and a main body; round holes are formed on two sides of the bracket and the main body and are engaged with a nut through a screw; and a mechanical power-off connecting wire resistor is arranged in the middle of the left bracket. The brake crank is suitable for bicycles and electric vehicles and has good brake effect, good handfeel and sensitivity; and moreover, the brake crank is smooth and labor-saving in manual labor relative to a pull wire disc brake, and adverse slope of the vehicle can be well prevented.
Description
Technical field
The present invention relates to a kind of brake lever, relate in particular to a kind of brake lever that is suitable for self-moving vehicle or battery-driven car.
Background technology
Along with development of science and technology, the design of increasing disc brake also has the materials aspect, all begins to reduce weight, so disc brake is towards lightweight, high sensitivity, and the easy aspect of relative adjustment has designed.Once official data showed; The shimano950v of the old money system of stopping; Weight difference distance in the shimano960 of latest version disc brake entire system inner room is no more than 100g; Therefore this just suffices to show that, along with present development in science and technology, improves the manufacturing weight-saving scientific and technological content of disc brake greatly., really be necessary to adopt disc brake?
With regard to present everybody's usage degree, it is not first-selected feeling and using disc brake.Not the investment problem of money, but the degree of the application maintenance of brake.To the university student, general fan adopts a cover to use v to stop, if the product mix that cooperates conforming to is suitable, the effect that v stops is all well and good.Maintenance, maintenance, debugging, when these several aspects all will be carried out, everybody utilized the instrument of a combination folding just can solve basically.And debug, common people can both accept.The maintenance process of not thinking disc brake bothers so.If involve maintenance, very simple of the physical construction that v stops, basically oneself can both be suitable the defect place under repair; And part cost aspect from keeping in repair; Concerning the university student fan, also can both accept, and result of use, it is no problem using sufficient 5000km.And lean on the disc brake of cable pulling theory of machines, may be because of all factors such as length, elasticity and shell friction of line itself, and [brake] power that run off.Meet humidity, rainy day, [brake] usually is accompanied by birdie.
Summary of the invention
The object of the present invention is to provide a kind of bicycle and battery-driven car of being applicable to have good braking effect, good hand touch, sensitivity.The relative backguy dish of power on hand kills more along sliding laborsaving and can better prevent the brake lever of car two adverse slopes.
Technical scheme of the present invention is: a kind of brake lever; Comprise pressing board, spring, rivet, handle, draw buckle, pipe rivet and left tray; Be provided with a spring between said pressing board bottom and the said handle cavity volume, said draw to buckle be provided with slotted eye and pass on the fixing said handle of slotted eye through said rivet, the front of said left tray is provided with a groove and said buckle interlock mutually by front edge of board; Said left tray comprises support and main body; Said support and main body both sides have circular hole, and through screw and nut together, also are provided with mechanical type outage connection lead in the middle of the said left tray and hinder.
In preferred embodiment of the present invention, described nut and screw are to be processed by corrosion-resistant steel.
In preferred embodiment of the present invention, described left tray lower end is provided with the mounting hole that supplies brake lever to install.
In preferred embodiment of the present invention, the resistance of described mechanical type outage connection lead comprises Hall element and magnet steel.
A kind of brake lever of the present invention is applicable to that bicycle and battery-driven car have good braking effect, good hand touch, sensitivity.The relative backguy dish of power on hand kills more along sliding laborsaving and can better preventing car two adverse slopes.
Description of drawings
Accompanying drawing 1 is the perspective view of brake lever one preferred embodiment of the present invention.
The mark of each parts is following in the accompanying drawing: 1, pressing board, 2, spring, 3, rivet, 4, handle, 5, draw button, 6, pipe rivet, 7, left tray.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1; Fig. 1 is a kind of brake lever of the present invention, said brake lever comprises pressing board 1, spring 2, rivet 3, handle 4, draw buckle 5, pipe rivet 6 and left tray 7 form, and is provided with a spring 2 between said pressing board 1 bottom and said handle 4 cavity volumes; Saidly draw button 5 to be provided with slotted eye and pass on the fixing said handle 4 of slotted eye through said rivet 2; The front of said left tray 7 is provided with the buckle interlock mutually of a groove and said pressing board 1 front end, and said left tray 7 comprises support and main body, and said support and main body both sides have circular hole; And through screw and nut together, also be provided with mechanical type outage connection leads in the middle of the said left tray 7 and hinder.
In one embodiment, described nut and screw are to be processed by corrosion-resistant steel, and described left tray 7 lower ends are provided with the mounting hole that supplies brake lever to install, and the resistance of described mechanical type outage connection lead is made up of Hall element and magnet steel.
Further specify, when brake, the said buckle of pressing front edge of board passes through clamp button of the spring in the fwd groove of said left tray, and the blocking-up of mechanical type outage connection lead is opened, and cuts off the motor power supply, unclamps the meeting of moving certainly of brake lever spring, and circuit is connected.The present invention provides a kind of brake lever, is applicable to that bicycle and battery-driven car have good braking effect, good hand touch, sensitivity.The relative backguy dish of power on hand kills more along sliding laborsaving and can better preventing car two adverse slopes.
The specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
