Abstract
The invention discloses a kind of band microswitch hydraulic brakes, including bulb push rod (3), sliding sleeve (6), microswitch (7), caliper (13), lower pump body (14) and lower pump piston (15), present invention employs microswitch interior design structures and split type lower pump configuration, using the method for thinned cylinder wall.Relative to the hydraulic disc brake generally used at present, such design electric switch that has been both water brake band and the angle for facilitating regulation handle adapt to the different size of hand of different users, reducing volume reduces material weight, is convenient to use.
Description
Technical field
The present invention relates to hydraulic disk type brakes used in bicycle, electric bicycle and motorcycle, referred to as hydraulic
Disc brake.
Background technique
Hydraulic disc brake is widely used in bicycle, electric bicycle and motorcycle, and hydraulic disc brake is the portion of these vehicles indispensability
Part.Currently used hydraulic disc brake is easy to produce following deficiency due to design structure and manufacture: first is that, exposed is micro-
Dynamic switch makes shape become larger, and moulding is bad, and microswitch is easy to damage.Second is that lower pump integral type moulding is bigger than cumbersome volume.
Summary of the invention
For defect existing for above-mentioned existing technology, the present invention is with microswitch hydraulic brake purpose: providing
A kind of structure of the built-in small volume of microswitch, while being reduced using the method for split type lower pump configuration and thinned cylinder wall
Volume reduces weight.
It realizes the technical scheme is that such: a kind of band microswitch hydraulic brake, including bulb push rod, cunning
Dynamic set, microswitch, caliper, lower pump body and lower pump piston, it is characterised in that: have blocking outstanding on the bulb push rod
Ring；The sliding sleeve covers on bulb push rod, in static state, sliding sleeve is on one side with being slidably matched in bowl-type annular shape
It is against on blocker ring, the surface of another side bowl-type is against on the contact steel disc of microswitch；The microswitch is installed in
In the internal cavity of upper pump casing, positioned at the lower section of bulb push rod, it is fixed on upper pump casing by primary screw；The caliper is L-shaped,
Caliper has the notch of two receiving movable strips of friction plate, there is the hole for placing fixed screw, and caliper has reinforcing rib and loss of weight
Through-hole；There is the screw hole for installing caliper on the lower pump body, two oil har opening inner walls on lower pump body are to be fitted without to appoint
The continuous smooth surface of what sealing ring, the connection of two oil cylinders is that straight line drilling processing forms on lower pump body；Described
There are 2 or 3 annular grooves on lower pump piston, lower pump gland is installed on annular groove.
The microswitch has normally opened and normally closed conductive contact.
The diameter of blocker ring outstanding on the bulb push rod is greater than the diameter of sliding sleeve mesoporous, the mesoporous of sliding sleeve
Diameter is greater than the diameter of bulb push rod bar portion, and sliding sleeve can be slided swimmingly in bulb push rod bar portion.
This band microswitch hydraulic brake not only solves the problems, such as installation microswitch, and the angle of brake handle
It spends adjustable.The hydraulic disc brake band of electric bicycle in reality microswitch, often handle angle is non-adjustable.
The invention has the advantages that it is built-in to provide a kind of microswitch relative to the hydraulic disc brake generally used at present
The lesser structure of co-volume, while volume is reduced using the method for split type lower pump configuration and thinned cylinder wall and reduces weight.
Detailed description of the invention
Here is Detailed description of the invention:
Fig. 1 is the cross-sectional view of the upper pump portion of a specific embodiment of the invention with microswitch hydraulic brake.
Fig. 2 is the exploded perspective figure of upper pump portion.
Fig. 3 and Fig. 4 is the perspective view and front view of lower pump portion.
Fig. 5 is the exploded perspective figure of lower pump portion.
Specific embodiment
Below with reference to implementing, the invention will be further described.
Fig. 1 is the upper pump portion cross-sectional view of a specific embodiment of the invention with microswitch hydraulic brake, knot
Close Fig. 2 to be described as follows: when manpower is held with a firm grip handle 1, handle 1 drives cylindrical nut 2 to be moved along, bulb push rod 3 and cylindrical nut 2
Between be to be threadedly engaged, such cylindrical nut 2 drives bulb push rod 3 to squeeze into the oil har opening of upper pump casing 10, and bulb pushes away
Bar 3 pushes oil har opening depths to for small piston 4, and oil pressure is passed to lower pump body by oil pipe by small piston 4 and upper pump gland 5
14, lower pump piston 15 travels forward, and is just pressed adjacent to friction plate 17, forms the braking brake to disc.It is static in handle 1
When, small piston 4 and the top of bulb push rod 3 are arrived extreme position by reset spring 8, this extreme position is determined by gasket 9 and circlip 11
Fixed, the blocker ring 3.1 on bulb push rod 3 withstands on sliding sleeve 6 on the contact steel disc of microswitch 7, and the bending of contact steel disc will
The contact of microswitch 7 is pressed into, and makes switch motion.It is sliding when handle 1 drives cylindrical nut 2 and bulb push rod 3 to be moved along
Dynamic set 6 loses the pressure of blocker ring 3.1, and the contact steel disc of microswitch 7 is just sprung back, and acts switch again.Bulb push rod 3
On have a blocker ring 3.1 outstanding, sliding sleeve 6 be it is circular in bowl-type, cover with being slidably matched on bulb push rod 3, quiet
Sliding sleeve 6 is against on blocker ring 3.1 on one side when state, and the surface of another side bowl-type is against on the contact steel disc of microswitch 7；It is micro-
Dynamic switch 7 is fixed in the cavity of upper pump casing 10 by primary screw 12, is not easy to be damaged.The method for installing microswitch 7 is interior
Concealed, be a kind of structure of small volume.
Fig. 3 and Fig. 4 is the perspective view and front view of lower pump portion, and Fig. 5 is the exploded perspective figure of lower pump portion.In conjunction with this three
Open figure to be described as follows: when the liquid of upper pump is pressed into lower pump body 14, two lower pump pistons 15 are just pushed outwardly, and friction plate 17 leans on
The side of nearly caliper 13 is the not no route of retreat, and as a result two panels friction plate presses against together, results in brake force.Lower pump portion is
Seperated, caliper 13 is L-shaped, and caliper 13 has the notch of two receiving movable strips of friction plate 17, there is placement fixed screw
18 hole, caliper 13 have reinforcing rib and loss of weight through-hole；There is the screw hole for installing caliper 13 on lower pump body 14, on lower pump body 14
Two oil har opening inner walls are the continuous smooth surfaces for being fitted without any sealing ring, and Fig. 4 clearly shows on lower pump body 14 two
The connection of oil cylinder is that straight line drilling processing forms；There are 2 or 3 annular grooves on lower pump piston 15, it is close that lower pump is installed
Seal 16.Such purpose of design is: volume reduced using the method for split type lower pump configuration and thinned cylinder wall and reduces weight,
Shape is more small and beautiful simultaneously.
Microswitch 7 can be user-friendly with normally opened and normally closed conductive contact.
The diameter of blocker ring outstanding 3.1 on bulb push rod 3 is greater than the diameter of 6 mesoporous of sliding sleeve, the mesoporous of sliding sleeve 6
Diameter is greater than the diameter of 3 bar portion of bulb push rod, and sliding sleeve 6 can be slided swimmingly in 3 bar portion of bulb push rod, and such design is both
Brake ribbon electric switch, and the angle of regulation handle 1 can be facilitated, adapt to different users different size of hand.
