Abstract
The invention relates to an auto spare part, and discloses a non-contact waterproof and dustproof switch. The switch comprises a substrate and a housing. The housing is fixedly mounted on the substrate, a printed circuit board (PCB) is disposed on the substrate, Hall units are disposed on the PCB board, and actuating mechanisms are disposed on the housing and are internally provided with magnets corresponding to the Hall units. The magnets are used for inducting the Hall units so as to realize a switch function, such that the switch provided by the invention is of a non-contact type, is not restricted by application frequency and thus has no service life problems; the switch function of the non-contact waterproof and dustproof switch is only related to the magnetic field strength of the magnets, copper elastic sheets and too many rubber materials are unnecessary, and thus material-related influences of fatigue stress relaxation and permanent compressive deformation are avoided; and a waterproof partition plate is disposed between the housing and the substrate, and two chambers which are not communicated with each other at all are formed, such that complete water tightness of the PCB board is realized, and the switch is simple in overall structure.
Description
Technical field
The present invention relates to the accessory of automobile, be specifically related to a kind of contactless water proof and dust proof switch.
Background technology
Mostly the switch that automobile is now used is to adopt rubber key and the sensitive switch of one or more contacts to realize the function such as electronic parking and start and stop, and rubber key provides feel and switch over travel function simultaneously; But rubber key ubiquity problem in useful life, be generally left and right 300,000 times, simultaneously the switching function of rubber key and sensitive switch along with useful life variation gradually, it is lax that copper material shell fragment in sensitive switch can produce fatigue stress, feel and the switch over travel of switch all can be affected, lose efficacy even; And rubber key also can produce permanent compressive deformation, and the feel of switch and switch over travel all can be affected.
Along with the increase of people's motion frequency in car; the waterproof requirement of safety member in car is also increased gradually; adopt rubber key and the sensitive switch of contact; actuator's moving conduit is from top to down inevitable; although technology has adopted a lot of methods to carry out PCBA plate in protection switch at present; but all can not enter PCBA plate by completely anti-sealing, and make thus whole construction of switch become very complicated.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of contactless water proof and dust proof switch, its object: water proof and dust proof, and without problem in useful life.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of contactless water proof and dust proof switch, comprises pedestal and housing, and described housing is fixedly mounted on pedestal, between housing and pedestal, is provided with waterproof bulkhead;
Described pedestal is provided with pcb board, and pcb board is provided with the first Hall unit and the second Hall unit, and housing is provided with the first actuator and the second actuator;
In the first actuator, be provided with first magnet corresponding with the first Hall unit, in the second actuator, be provided with second magnet corresponding with the second Hall unit;
Between the second actuator and waterproof bulkhead, be provided with rubber key.
Preferably, the first magnet and the second magnet are permanent magnet.
Pass through technique scheme, described housing is fixedly mounted on pedestal, pedestal is provided with pcb board, pcb board is provided with Hall unit, and housing is provided with actuator, is provided with the magnet corresponding with Hall unit in actuator, respond to Hall unit by magnet and realize switching function, be a kind of non-contact switch mode, there is no access times restriction, without problem in useful life; The switching function of this contactless water proof and dust proof switch is only relevant to the magnetic field intensity of magnet, does not need to use copper material shell fragment and too much elastomeric material, has avoided the fatigue stress that material is relevant to relax and the impact of permanent compression set on switch over travel; Between housing and pedestal, be provided with waterproof bulkhead, form two cavitys that do not communicate completely, thereby realized the complete waterproof of pcb board, and overall structure is simple.
