Abstract
The invention discloses a bidirectional brake limiting structure which comprises a brake wrench which is fixed on a brake axle and contacts with a brake switch, wherein when a motor operates normally, the brake wrench is in a vertical state; and an end cover of the brake axle is provided with a limiting device for limiting the pull position of the brake wrench. If a user releases the brake with excessively large force, the brake wrench is just pushed against the limiting device but not pulled to the brake position in another direction, the brake state of the motor is released, and the motor enters the normal operation state; and the limiting device is arranged at the same side of a wheelchair as the brake wrench according to the force applying habit of the user.
Description
Technical field
The present invention relates to the motor braking structure, particularly a kind of bidirectional brake limiting structure.
Background technology
In the brake structure of motor, particularly in the brake structure of wheel-chair motor, general all is the structure that adopts bidirectional brake, namely on both direction, can carry out the operation of skidding, therefore just individual problem is arranged here, be exactly when removing the braking state of motor, the user may overexert, brake is pulled on the skidding position of another direction, this moment, motor still was in braking state, and user oneself is unclear and starter motor, and motor has burnt out because of overlond running with regard to being very easy to like this.
Summary of the invention
Problem to be solved by this invention just provides a kind of bidirectional brake limiting structure, rational in infrastructure, simple, the direction of brake is set according to user habit, and when avoiding occurring removing brake brake is pulled the situation of another normal danger, prolong motor service life.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of bidirectional brake limiting structure, comprise and be fixed on the brake spanner that contacts with brake switch on the brake axle, when motor normally moves, the brake spanner is in vertical state, it is characterized in that: be provided with restriction brake spanner at the end cap of brake axle and pull the stopping means of position.
Further, described stopping means comprises the threaded fastener on the end cap that is located at brake axle, the left side of brake spanner when threaded fastener is contained in motor and normally moves.
Further, described stopping means comprises the threaded fastener on the end cap that is located at brake axle, the right side of brake spanner when threaded fastener is contained in motor and normally moves.
Further, the distance between described screw fastener head end face and the brake axle end cap end face is greater than the distance between brake spanner medial surface and the brake axle end cap end face.
Further, described threaded fastener is bolt.
Further, described threaded fastener is screw.
Further, described stopping means comprises the elastic component and the steel ball that is located on the elastic component on the end cap that is located at brake axle, be provided with the installing hole of setting-in elastic component and steel ball at the end cap of brake axle, the diameter of installing hole oral area is less than the diameter of steel ball, elastic component withstands on steel ball the oral area of installing hole, and steel ball exposes the end face of brake axle end cap and half that exposed portions serve is no more than steel ball.
The left side of brake spanner when further, described stopping means is located at motor and normally moves.
The right side of brake spanner when further, described stopping means is located at motor and normally moves.
Left side and the right side of brake spanner when further, described stopping means is located at motor and normally moves.
After adopting technique scheme, the present invention has following advantage: after spacing by threaded fastener, if the user overexerts when removing brake, the brake spanner also just is against on the threaded fastener, can't be with the switching of brake spanner on the normal danger of other direction, the motor brake status releasing enters normal operating condition; Threaded fastener is installed in which side of wheel-chair according to the brake spanner, and user's self left side or the right side of firmly being accustomed to being arranged on the brake spanner, has more hommization; If wish to keep the bidirectional brake function, then come to carry out spacing to the brake spanner by elastic component and steel ball, if the user overexerts when removing brake, the brake spanner can be crossed steel ball and bump with the steel ball wiping, the user can have the feel of colliding with to and hear that metal wipes the sound that bumps, the user just knows that brake is excessive like this, and motor is not removed brake, makes things convenient for the user in time to adjust the braking state that the brake spanner is removed motor.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the first embodiment of the present invention;
Fig. 2 is the structural representation after structure relatively shown in Figure 1 is done to change;
Fig. 3 is the structural representation of the second embodiment of the present invention;
Fig. 4 is the mounting structure schematic diagram of elastic component and steel ball.
The specific embodiment
Embodiment one:
The structural representation of an embodiment of the present invention as shown in Figure 1, a kind of bidirectional brake limiting structure, comprise and be fixed on the brake spanner 3 that contacts with brake switch 2 on the brake axle 1, when motor normally moves, the brake spanner is in vertical state, is provided with restriction brake spanner at the end cap 4 of brake axle and pulls the stopping means of position.Described stopping means comprises the threaded fastener 5 on the end cap that is located at brake axle, the left side of brake spanner when threaded fastener is contained in motor and normally moves.
As shown in Figure 2, structure relatively shown in Figure 1 is done a bit to change, the right side of brake spanner when threaded fastener is contained in motor and normally moves.Here threaded fastener is installed in which side of wheel-chair according to the brake spanner, and user's self firmly custom arranges.
In above-described embodiment, distance between described screw fastener head end face and the brake axle end cap end face is greater than the distance between brake spanner medial surface and the brake axle end cap end face, overexert when the user brakes like this and the brake spanner can not be overstroke, only can withstand on the threaded fastener and can not enter rightabout normal danger.Threaded fastener is bolt or screw.
Embodiment two:
Embodiment one is constrained to unidirectional brake with bidirectional brake, if wish to keep the bidirectional brake function, carry out shown in Fig. 3 and 4, arranging, described stopping means comprises the elastic component 6 and the steel ball 7 that is located on the elastic component on the end cap that is located at brake axle, be provided with the installing hole 41 of setting-in elastic component and steel ball at the end cap of brake axle, the diameter of installing hole oral area is less than the diameter of steel ball, elastic component withstands on steel ball the oral area of installing hole, and steel ball exposes the end face of brake axle end cap and half that exposed portions serve is no more than steel ball.Left side or the right side of brake spanner when stopping means can be located at motor and normally moves, perhaps the left and right sides all arranges.If the user overexerts when removing brake, the brake spanner can be crossed steel ball and bump with the steel ball wiping, the user can have the feel of colliding with to and hear that metal wipes the sound that bumps, the user just knows that brake is excessive like this, motor is not removed brake, makes things convenient for the user in time to adjust the braking state that the brake spanner is removed motor.
Correspondingly, when the user will brake, if the spanner that will brake pull to the direction that is provided with steel ball, the user feel collide with after explanation finished brake.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
