Abstract
The utility model relates to a rear brake switch which is mounted on the inner side of the rear wheel foot brake of a motorcycle or an electric motorcycle and used for controlling the open and the close of a rear brake lamp. The rear brake switch structurally comprises a housing; the lower end of the housing is connected with a rubber sleeve; a seal ring is arranged at the uppermost end in the housing; a gasket is arranged under the seal ring; a pull rod is arranged in a spring under the gasket; a fixing block is arranged at the lower end of the pull rod; a return block in contact with the pull rod is arranged in the fixing block; a spring return fixing rod is arranged in the return block; trapezoid springs are arranged above the spring return fixing rod and on the outer side of the return block; the lower end of the spring return fixing rod is in contact with a contact piece; a spring leaf is in contact under the contact piece; a contact pin is arranged on the two sides of the spring leaf respectively and connected with a conductor; and a fixing seat is arranged under the spring leaf. Compared with the prior art, the rear brake switch has more reasonable design, simpler structure, higher seal security and longer service life, and produces a smaller electrical arc due to contact.
Description
Technical field
The utility model relates to and a kind ofly is installed in motorcycle and electric motorcycle back wheels of vehicle pin is stepped on the inboard, is used to control the switch of rear brake lamp, specifically provides a kind of back brake switch.
Background technology
Rear brake lamp control switch under the prior art, its general movable type that adopts contacts conducting, and electric arc is big during contact, loses efficacy easily, has shortened life of product; And product do not have sealing, and because of outside product is installed in, no seal approach is just frozen under low-temperature condition easily, easy ponding, and the contamination dirt does not work the vehicle rear brake lamp when brake, bring hidden danger for traffic safety, lives and properties.
Summary of the invention
The utility model is at above problem, and a kind of back brake switch is provided, and it adopts shell fragment flip-over type contact conducting, can alleviate the electric arc that contact produces, and safe sealing is arranged, and guarantees switch life.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of back brake switch, comprise shell, the shell lower end connects rubber sleeve, top is provided with sealing ring in the described shell, described sealing ring below is provided with pad, be provided with pull bar in the spring of described pad below, described pull bar lower end is provided with fixed block, is provided with the return piece that is connected with described pull bar contact in the described fixed block, is provided with spring return fixed lever in the described return piece, described spring return fixed lever top and return piece arranged outside have trapezoidal spring, described spring return fixed lever lower end contacts with contact, and contact contact down has shell fragment, shell fragment both sides respectively to be provided with a contact feet, contact feet is connected with lead, and described shell fragment below is provided with holder.
Housing exterior is provided with exterior nut cap.
The rubber sleeve outer setting has buckle.
A kind of back of the present utility model brake switch, its sealing ring top in the enclosure, can prevent extraneous rainwater, dust etc. drain to switch inside, are placed with pad below the sealing ring, be used for fixing the spring under sealing ring and the pad, pull bar passes spring, pad, sealing ring, extends to the outside always, and the pull bar below is provided with fixed block, return piece, the return piece places in the middle of the fixed block, and fixed block is used for fixing pull bar and return piece.Be placed with a trapezoidal spring under the return piece, trapezoidal spring top sub-fraction is equipped with spring return fixed lever under the trapezoidal spring in the return piece, spring return fixed lever, pass trapezoidal spring, top contacts with the return piece, and the bottom contacts with contact, and contact contact down has shell fragment, the shell fragment both sides respectively are provided with a contact feet, contact feet is connected with lead, and contact contacts with contact feet, circuit turn-on; Contact separates with contact feet, and circuit disconnects.Contact is arranged with holder.
Switch the first half is provided with shell, and shell is outside equipped with exterior nut cap, when this nut is installed on the vehicle at product, plays fixation; Switch the latter half cover rubber sleeve, the rubber sleeve afterbody is provided with and diameter of wire two holes of the same size, lead and rubber sleeve are closely interlocked, rubber sleeve is furnished with buckle outward, buckle links closely shell and rubber sleeve, thereby makes whole switch sealing, prevents the outside rainwater, entering of dust causes loose contact even short circuit.
So, a kind of back of the present utility model brake switch compared with prior art, have that reasonable in design, simple in structure, contact produces that electric arc is little, the high property of sealingly secure, useful life characteristics of a specified duration.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of a kind of back brake switch;
Fig. 2 be a kind of back brake switch partly cut open structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments a kind of back of the present utility model brake switch is further described.
As shown in drawings, a kind of back brake switch, comprise shell 1, shell 1 lower end connects rubber sleeve 2, top is provided with sealing ring 3 in the described shell 1, described sealing ring 3 belows are provided with pad 4, be provided with pull bar 6 in the spring 5 of described pad 4 belows, described pull bar 6 lower ends are provided with fixed block 7, be provided with the return piece 8 that is connected with described pull bar 6 contacts in the described fixed block 7, be provided with spring return fixed lever 9 in the described return piece 8, described spring return fixed lever 9 tops and return piece 8 arranged outside have trapezoidal spring 10, and described spring return fixed lever 9 lower ends contact with contact 11,11 times contacts of contact have shell fragment 12, shell fragment 12 both sides respectively are provided with a contact feet 13, and contact feet 13 is connected with lead 14, and described shell fragment 12 belows are provided with holder 17.
Shell 1 outer setting has exterior nut cap 15.
A kind of back of the present utility model brake switch in use, switch is when external force pulling function, pull bar 6 rises, separate with return piece 8, return piece 8 belows are equipped with trapezoidal spring 10, and trapezoidal spring 10 belows are equipped with spring return fixed lever 9, spring return fixed lever 9 contact contacts 11,11 times contacts of contact have shell fragment 12, when trapezoidal spring 10 separates with return piece 8 at pull bar 6, and pressurized not, shell fragment 12 upwards arches upward, contact 11 is contacted with contact feet 13, thereby make circuit turn-on, rear brake lamp is bright.
The spring return ejects pull bar 6 downwards, and pull bar 6 is pushed up back return piece 8, along with the return of return piece 8, trapezoidal spring 10 that is attached thereto and spring return fixed lever 9 be effect downwards also, makes shell fragment 12 recessed, thereby contact 11 and contact feet 13 are separated, and circuit disconnects, and rear brake lamp does not work.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
