Specific embodiment

As shown in Figures 1 to 4, the utility model braking light switch, it is total including fixed seat assembly 1, resetting spring 2, shell point Into 3, push rod 4 and sliding block 5.

The fixation seat assembly 1 is structure as a whole, and storage tank 11 is offered from top down；The inner wall note of the storage tank 11 Modeling is divided into dielectric and conducting medium, and interior bottom center is convexly equipped with positioning column 12；Wherein, 1 opposite sides of fixation seat assembly The lower end of outer wall is also convexly equipped with guide ledges 13（Match with slip recess and realize axially directed slip）.

The resetting spring 2 matching is sheathed in the fixation seat assembly 1 on the positioning column 12 of bottom, and the upper end is sheathed on sliding block Spring socket in, spring is made to withstand sliding block and push rod, is the original state that the state is product.

The shell sub-unit 3 is installed on outside fixed seat assembly 1, including shell 31 and hollow screwed pipe 32.Wherein, this is outer The matching of shell 31 is covered at outside fixed seat assembly 1, and lower end housing opposite sides is equipped with card hole 311 and by card hole 311 and admittedly The fixture block 13 of 1 lower end of reservation assembly is connected；The outer center of top of the shell 31 is outwardly, inner cavity and fixed seat assembly 1 Storage tank 11 connect.The hollow screwed pipe 32 is steel structure（Rigidity and intensity ensure）, axially inside penetrate through and offer Pore, outside offer screw thread；The lower end of the hollow screwed pipe 32 and the top of shell 31 are molded into an entirety, outside the tube body of stage casing Portion is rotary with nut 33 by screw thread；The nut 33 is fixed on the pedal of vehicle.（Brake pedal brake while the braking in tailstock portion Circuit for lamp connection Brake lamp is bright, plays prompting front vehicle and pays attention to seeing Fig. 5 Brake lamp operation principles）

The push rod 4 is No. 45 steel of metal, is arranged in the hollow screwed pipe 32 of shell sub-unit 3, upper end is pierced by hollow spiral shell 32 top of pipe, lower end stretch into 31 inner cavity of shell and end through hollow screwed pipe 32 and are equipped with cylindrical jacking block 41；Wherein, the push rod 4 bodies of rod penetrated in hollow screwed pipe 32 and rubber seal 42 is also folded between hollow screwed pipe 32, the push rod 4 and the push rod 4 Coordinate the quality stability for adding product with the hollow screwed pipe 32 of steel, coordinate with the hollow screwed pipe 32 of steel, ensure product Motion stabilization and shock resistance.Because driver will frequently touch on the brake when driving, the particularly busy street in city crosses traffic lights With, it is necessary to frequently brake, push rod 4 and hollow 32 rubs mutually of screwed pipe, added metal pedal is single to 4 head of push rod when crossing pavement To impact；Metal and metal friction, so anti-reflective answers frequent impact.

In the cavity that the storage tank 11 of shell 31 and fixed seat assembly 1 that the sliding block 5 is located at shell sub-unit 3 is formed, Peripheral outer wall is slidably connected to the internal chamber wall of shell 31 and the internal groove side wall of storage tank 11；Wherein, it is in convex shape knot that the sliding block 5 is whole Structure, center of top convexes to form lug boss 51 and lug boss 51 connects the jacking block 41 of push rod 4, is opened upwards from bottom center Equipped with resetting spring slot 52；In 2 upper end of resetting spring insertion resetting spring slot 52；Meanwhile the sliding block 5 is in its top bump portion Both sides symmetrically offer mounting groove 53 along its length and symmetrical at both sides mounting groove 53 fixed there are two movable contact springs 54；Two Movable contact spring 54 is symmetrical bending structure, and 53 slot bottom of mounting groove is fixed in middle part by fixed block 55 triangular in shape, Both ends protrude out to 5 width of sliding block outside and rivet the bulb contact 541 inwardly received；Each bulb contact 541 is to cunning 5 width of block is stretched out and connected with 11 inner wall of storage tank of fixed seat assembly 1；Since nut 33 is fixed on stepping on for vehicle It on plate, is acted by pedal and promotes push rod 4, then sliding block 5 is promoted by push rod 4, make bulb contact 541 in 5 width of sliding block It is slided along 11 inner wall of storage tank of fixed seat assembly 1, using the outside elastic force of movable contact spring, movable contact spring is made to be produced with fixed seat inner wall Raw pressure, pressure are transmitted to bulb contact, and then make A on 541 displacement storage tank of bulb contact, 11 inner wall, medium B（A is plastics Medium or dielectric, B are metal medium or conducting medium）And connecting and disconnecting are generated, generate the connecting and disconnecting system such as Fig. 4 The function of dynamic lamp；Brake being stepped in driver to light with constantly Brake lamp requirement, unclamping footbrake, Brake lamp requirement is extinguished Function.（As illustrated in Figures 5 and 6）

The structure design of the utility model is reasonable, compact, and performance is more stablized, and improves connection and waterproofing grade, cost is bright Aobvious to reduce, operability is stronger.
