[embodiment]
As shown in Fig. 1 ~ 2, the pushbutton unit 100 of an embodiment, comprises housing 110, button 120 and switch module 130.
Housing 110 has upper surface 111 and lower surface 112.Upper surface 111 is provided with button hole 113, and button 120 is contained in button hole 113.Lower surface 112 is provided with opening, and switch module 130 is contained in housing 110 by the opening of lower surface 112.The inner side of housing 110 is provided with holding section 114.Holding section 114 extends around button hole 113 1 weeks and along the axis of button hole 113.Button 120 one end is provided with stop part (figure does not mark).Stop part around outside it one week, and prevents button 120 from deviating from from button hole 113.Stop part is provided with and rounds and the auxiliary section 121 fastened with holding section 114.Switch module 130 compresses button 120, makes the contact-making surface of holding section 114 and auxiliary section 121 form hermetically-sealed construction.In the present embodiment, holding section 114 is along the axially extended snap fit tabs of button hole, and auxiliary section 121 is along the axially extended groove of button hole.Above-mentioned pushbutton unit by arranging along the axially extended holding section 114 of button hole 113 on housing 110, button 120 arranges the auxiliary section 121 fastened with holding section 114, match with auxiliary section 121 in holding section 114, to improve the sealing between housing 110 and button 120, thus water, dust etc. is avoided to enter the switch module 130 polluting in housing 110 and be contained in housing 110.Therefore, above-mentioned pushbutton unit is waterproof, dust-proof.
Above-mentioned pushbutton unit can be applied on light fixture, and when can effectively prevent light fixture from using in rugged environment, rainwater or dust invade the inside of light fixture, cause circuit failure or short circuit.
Concrete, button 120 is cavity structure.Button 120 has an openend 122, and its end face relative with openend 122 is formed and compresses structure 123.In the present embodiment, the material of button 120 is elastomeric material.The size of button 120 is less than the size of button hole 113, and button 120 elastic deformation can occur in button hole 113.Housing 110 also comprises the spacing preiection 115 nested with holding section 114, and the height of spacing preiection 115 is greater than the height of holding section 114.Spacing preiection 115 can be nested with holding section 114 or nested outward, in the present embodiment, is nested in holding section 114 outside spacing preiection 115.The material of housing 110 is hard material.
As shown in figures 1-4, switch module 130 is the structure with the inner wall shape adaptation of housing 110, such as cuboid or cylinder.In the present embodiment, switch module 130 is cuboid cavity.Switch module 130 has first end 131, second end 132 relative with first end 131.The end face of first end 131 is provided with through hole 133.The inside of switch module 130 is provided with switch module 134, and switch module 134 has press key pole 1341.Press key pole 1341 is slender structure.In the present embodiment, press key pole 1341 is elongated cylinder.Press key pole 1341 partially passes through through hole 133 and is exposed.Switch module 130 passes through the openings house of the lower surface 112 of housing 110 in housing 110.The end face of the first end 131 of switch module 130 compresses the openend 122 of button 120.Press key pole 1341 is put in the cavity of button 120 by openend 122.Just the pressing to press key pole 1341 can be produced by the face that compresses 123 of button 120.Utilize the displacement stroke required for elastic deformation generation pressing keys bar 1341 of button 120 during pressing.
Further, in order to anti-sealing, dust etc. enter in switch module 134 from the seam crossing of press key pole 1341, stop part is located at the outer peripheral edges of the openend 122 of button 120, and the shell of stop part and switch module 130 abuts against, jointly to form the annular seal space of a collecting press key pole 1341.
In order to firm the holding in auxiliary section 121 of the holding section 114 with button 120 that make housing 110, to improve the sealing between housing 110 and button 120 further, above-mentioned pushbutton unit also comprises pressure holding piece 140 and locking member 150.
In the present embodiment, pressure holding piece 140 is U-shaped structure, and its two ends are extended with flank (figure does not mark).Second end 132 of switch module 130 is partially housed in pressure holding piece 140.The flank of pressure holding piece 140 is provided with two symmetrical through holes 141, and locking member 150 is screwed in housing 110 through through hole 141, screws locking member 150 and just can form extruding force to switch module 130.Switch module 130 controls by spacing preiection 115 in the displacement of housing 110 inside, just can be changed the displacement range of switch module 130 by the height changing spacing preiection 115, thus changes the extruding force of switch module 130 pairs of buttons 120.
Be appreciated that pressure holding piece 140 can replace to other shape, such as flat structure or cap-type structure, but will ensure to produce uniform extruding force to switch module 130.The number of through hole 141 can change, and is preferably symmetrical, and the degree of depth that locking member 150 screws in housing 110 is preferably consistent, can produce uniform extruding force like this, make to form good sealing between button 120 and housing 110.
Be appreciated that pressure holding piece 140 and locking member 150 can omit.Switch module 130 is cylinder.Helicitic texture is set in the inside of housing 110, switch module 130 arranges matching thread.Switch module 130 is screwed in housing 110, just can produces the extruding to button 120.
Be appreciated that the snap fit between button 120 and housing 110 can have multiple.Such as, auxiliary section 121 is along the axially extended bulge-structure of button hole 113, and holding section 114 is along the axially extended groove of button hole 113.Such as, or button 120 is set to the movable hermetically-sealed construction of energy, the snake fu jie structure of the elastic rubber layer that one deck is thin or Foldable near compressing face, face 123 part.The contact-making surface of button 120 and switch module 130 arranges the effect that O type circle reaches sealing further; Or on the contact-making surface of button 120 and control box assembly 130, fill one deck airtight and watertight padding to realize the effect of sealing.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
