Abstract
The utility model relates to a back-up lamp switch device belonging to the technical field of accessories for vehicles. The back-up lamp switch device comprises a contact, a switch trigger mechanism, a lead and a joint, wherein the contact is connected with the input end of the switch trigger mechanism, and the output end of the switch trigger mechanism is connected with the joint positioned in a back-up lamp through a lead. The back-up lamp switch device has the characteristics of simple structure, compact layout, low cost, reasonable design, accuracy in conducting signals and long service life.
Description
Technical field
The utility model relates to a kind of BLS device, belongs to automobile-used auxiliary technical field.
Background technology
Reversing lamp and switch thereof are one of necessary auxiliaries in the automobile.In the prior art, BLS is installed near the gearbox shifting bar, but it often has following defective: 1, and complex structure, parts are more, cost is higher; 2, volume is bigger, and distributing position disperses, difficult arrangement in the limited space of automobile; 3, be subject to the influence that contact weares and teares the useful life of switch; 4, be prone to the lamp indication that makes a mistake owing to loose contact during switch motion.
Can therefore, design a novel reversing lamp device to overcome above-mentioned defective, becoming those skilled in the art has technical barrier to be solved.
The utility model content
The utility model is intended to overcome the deficiency of prior art, and a kind of simple and compact for structure, accurate and lower-cost BLS device of signal conduction is provided.Its technical scheme that adopts is following:
This BLS device mainly comprises: contact, switch triggering mechanism, lead and joint, and wherein, contact is connected with the input of switch triggering mechanism, and the output of switch triggering mechanism is wired to the joint that is positioned at the reversing lamp place.
Preferably, contact plates wearing layer on its contact-making surface.
Compared with prior art, the utlity model has following advantage:
1, conducted signal is accurate: contact only is pressed into or ejects two kinds of selections, signal conduction when contact is pressed into, and the At time of eject signal breaks off, and the signal conduction is accurate, and phenomenon can not cause confusion; Conduct electricity very well, contact reliable material in the employing of conducting contact position, eliminate poor contact phenomenon;
2, wear-resisting, long service life: contact uses high-abrasive material after Overheating Treatment, to make the contact anti-wear performance stronger, the stroke of switch is affected and reduces the life-span;
3, cost is low: compact conformation, simple in structure, material cost reduction.
Description of drawings
Fig. 1: the BLS apparatus structure sketch map of the utility model.
1, contact; 2, switch triggering mechanism; 3, lead; 4, joint.
Embodiment
Below in conjunction with accompanying drawing and instance the utility model is described further:
An embodiment of the utility model is as shown in Figure 1; This BLS device mainly comprises contact 1, switch triggering mechanism 2, lead 3 and joint 4; Wherein, Contact 1 is connected with the input of switch triggering mechanism 2, and the output of switch triggering mechanism 2 is connected to the joint 4 that is positioned at the reversing lamp place through lead 3.
Produce wearing and tearing and reduction of service life in order to prevent that contact uses for more than 1 time in the use, contact 1 can use high-abrasive material to process, and perhaps on its contact-making surface, plates wearing layer.
Switch triggering mechanism 2 is the devices according to contact position decision-making circuit loop on/off, and it has bounce-back mechanism (for example spring), vehicle light power supply terminal, normally-closed contact and normally opened contact.When the contact At time of eject, under the elastic force effect of bounce-back mechanism, the vehicle light power supply terminal is connected to normally-closed contact, and circuit loop breaks off; When contact was pressed into, contact promoted bounce-back mechanism and overcomes its bounce, and the vehicle light power supply terminal is connected to normally opened contact, and circuit loop is connected.
In order to prevent the generation of poor contact phenomenon, can adopt at the conducting contact position to conduct electricity very well, contact reliable material, for example adopt the Metal Contact face, replace the some contact with the face contact.
The installation of this heat abstractor of brief description and the course of work: the contact in this BLS device 1 is installed near the position of automobile gearbox with switch triggering mechanism 2, and joint 4 is installed to the reversing lamp position; When automobile is hung when reversing gear, promote contact 1 motion by the angle on the back fork axle in the gearbox, contact 1 is pressed into and 2 actions of pull switch trigger mechanism, and the vehicle light power supply terminal is connected to normally opened contact, makes the circuit loop conducting, and reversing lamp is opened; When automobile from reversing gear the position when hanging up, the angle on the back fork axle in the gearbox is return, contact rebounds automatically under the effect of the in-house bounce-back of switch triggering mechanism, the vehicle light power supply terminal is got back to normally-closed contact, the circuit loop disconnection, reversing lamp is closed.
The utility model is more reasonable than traditional structure BLS compact conformation, long service life, and conducted signal is more accurate, can be widely used on the various automobile gearboxes such as car, minicar, commercial vehicle, microcaloire.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes done based on the utility model or modification all belong to the utility model and require the scope protected.
