Description
Technical field
This utility model relates to braking signal switch structure, is specially one and has single-contact fluid pressure type braking signal switch structure.
Background technology
Stop, tail and number plate light is usually the position being arranged on vehicle tailstock both sides, when driver's brake pedal, braking signal switch is connected and is made stop, tail and number plate light luminous, the driver reminding vehicle below notes, when the driver releases the brake pedal, braking signal switch disconnects and makes stop, tail and number plate light extinguish, and therefore the reliability of the construction of switch of stop, tail and number plate light is to ensure that the key factor of vehicle safe driving.
The contact block that in the construction of switch of traditional braking signal lights, two binding posts are different with two respectively carries out contacting realization conducting, the ON time of this version in use two binding posts is likely to inconsistent, this will cause the decline of stop, tail and number plate light serviceability, and serious will have influence on the driving safety of vehicle.
Utility model content
This utility model is intended to provide one can realize two binding posts and simultaneously turns on and close, and that improves braking signal switch reliability of structure has single-contact fluid pressure type braking signal switch structure.
This programme has single-contact fluid pressure type braking signal switch structure, including housing and enclosing cover, housing forms closed cavity with enclosing cover, housing offers fuel feed hole, fuel feed hole is connected with outer brake valve and communicates with closed cavity, fuel feed hole be arranged over flexible sheet, flexible sheet top is provided with mounting seat, mounting seat top is provided with contact plate, contact plate top is provided with contact block, cover outward and be respectively equipped with the first binding post and the second binding post, first binding post and the second binding post are attached by connecting sheet, first binding post is positioned at above contact block, it is additionally provided with reseting pressuring spring between sheet and mounting seat connecting, reseting pressuring spring one end offsets with being connected sheet, the reseting pressuring spring other end and mounting seat offset.
The principle of this programme is: during braking, outer brake valve is opened, highly pressurised liquid enters closed cavity from fuel feed hole, under the effect of the highly pressurised liquid in closed cavity, flexible sheet arches upward, flexible sheet arches upward and drives mounting seat, contact plate and contact block move upwardly together, contact block moves upward and contacts with the first binding post being in above contact block, first binding post conducting, under the effect connecting sheet, second binding post simultaneously turns on, stop, tail and number plate light is bright, after having braked, highly pressurised liquid stops passing into closed cavity from fuel feed hole, flexible sheet resets, simultaneously under the effect of reseting pressuring spring, mounting seat, contact plate and contact block move downward simultaneously, contact block and the first binding post separate, first binding post and the second binding post simultaneously switch off, stop, tail and number plate light goes out.
The effect of this programme is: the first binding post and the second binding post are attached by this programme by connecting sheet, and only contact block is set at the first binding post place, therefore when contact block and the first binding post contact, first binding post and the second binding post simultaneously turn on, when contact block and the first binding post separate, first binding post and the second binding post simultaneously switch off, this programme is compared with traditional structure, simultaneously turning on and disconnecting of the first binding post and the second binding post can be realized all the time, therefore the dependable performance of the braking signal switch structure of this programme, and simple in construction.
Further, entering the resistance of closed cavity to reduce highly pressurised liquid, fuel feed hole is splayed structure.
Further, enclosing cover is bakelite enclosing cover, and bakelite enclosing cover has good insulating properties.
Further, in order to housing and external rack are reliably connected, housing are also arranged with two installation sheets, installation sheet offers installing hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: housing 1, flexible sheet 2, enclosing cover the 3, second binding post the 4, first binding post 5, contact block 6, reseting pressuring spring 7, fuel feed hole 8, connection sheet 9.
Embodiment is substantially as shown in Figure 1: have single-contact fluid pressure type braking signal switch structure, including housing 1, the downside of housing 1 is provided with two installation sheets, two installation sheets are symmetricly set on the both sides of housing 1, installation sheet offers installing hole, housing 1 is attached by the installing hole on installation sheet and external rack, medium position at housing 1 is further opened with a fuel feed hole 8, this fuel feed hole 8 is in up-small and down-big splayed structure, this structure can reduce the resistance of liquid communication, the first groove and the two the second grooves it are provided with in the upside of housing 1, first groove is upper, second groove under, and first two ends, groove left and right distance more than the second groove effect two ends distance, the downside of the second groove communicates with fuel feed hole 8.
It is arranged over flexible sheet 2 at fuel feed hole 8, flexible sheet 2 is positioned at the first groove, it is provided with enclosing cover 3 on the top of flexible sheet 2, in this programme, enclosing cover 3 adopts bakelite enclosing cover 3, and bakelite enclosing cover 3 has good insulating properties, is provided with the 3rd groove at the middle part of enclosing cover 3, two ends, left and right on the downside of enclosing cover 3 are placed on flexible sheet 2, be additionally provided with mounting seat on the top of flexible sheet 2, mounting seat top is provided with contact plate, and contact plate top is provided with contact block 6.
