Embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of Waterproof electronic equipment, with reference to Fig. 1, in one embodiment, this Waterproof electronic equipment is filming apparatus, it comprises pcb board 300, upper casing 100 and lower casing 200, upper casing 100 matches with lower casing 200 and is formed for the container cavity of accommodating this pcb board 300, between upper casing 100 and lower casing 200, can link into an integrated entity securely by other any suitable securing members such as buckle structure, screw.In order to make the container cavity being formed by upper casing 100 and lower casing 200 there is water-proof function, thereby meet the requirement of fording operation, Waterproof electronic equipment of the present utility model also comprises the waterproof construction being arranged between upper casing 100 and lower casing 200, as example, will provide the detailed description of this waterproof construction below:
Referring to Fig. 2, in the present embodiment, this Waterproof electronic equipment also comprises the seal 400 being arranged between upper casing 100 and lower casing 200, be understandable that, the seal 400 is circulus, made by elastomeric material, such as silica gel, rubber and other any suitable soft elastomeric materials, thereby meet by producing elastic deformation the requirement that contact seals.In conjunction with Fig. 3 and Fig. 4, wherein upper casing 100 caves inward along the upper recess 110 circumferentially forming continuously of upper casing 100 towards the end face of lower casing 200, lower casing 200 caves inward along the lower concave part 210 circumferentially forming continuously of lower casing 200 towards the end face of upper casing 100, and upper recess 110 extends to the medial surface of upper casing 100, lower concave part 210 also extends to the medial surface of lower casing 200, in the time that upper casing 100 matches with lower casing 200, upper recess 110 and the seal groove of lower concave part 210 in conjunction with the accommodating seal 400 of formation.When assembling, first seal 400 is set on pcb board 300, the inner surface butt of the edge part of pcb board 300 and seal 400 also makes the seal 400 produce elastic deformation, here it should be noted that, the inside casing shape of seal 400 is similar to the frame shape of pcb board 300, thereby makes inner surface circumferentially closely the fitting together along seal 400 of edge part and the seal 400 of pcb board 300; Again pcb board 300 and the combination of seal 400 are embedded in upper recess 110 or lower concave part 210; Then upper casing 100 and lower casing 200 are combined, finally by matching used locking mechanism (as, buckle structure or screw) upper casing 100 and lower casing 200 are locked securely, now seal 400 by upper recess 110 and lower concave part 210 in conjunction with in the seal grooves that form by elastic compression, contact with the sealing that lower concave part 210 forms with upper recess 110 by seal 400, provide sealing function, to seal the department of assembly between upper casing 100 and lower casing 200.
Hence one can see that, waterproof construction of the present utility model has simple structure, assembles easy feature, because upper casing 100 matches and is formed for the seal groove of the accommodating seal 400 with lower casing 200, and seal 400 forms multi-sealed cooperation in sealing groove, therefore improve the waterproof effect of housing; In addition, the edge part of pcb board 300 is crimped on the inner surface of seal 400, waterproof effect that on the one hand can enhanced leaktightness part 400, on the other hand can be under the effect of the elastic-restoring force of seal 400 firm pcb board 300, reach the object of fixing pcb board 300, and then improve the utilance in enclosure interior space.
In the present embodiment, the cross sectional shape of upper recess 110 and lower concave part 210 is all L-shaped, and upper recess 110 comprises on first sealing surface 112 on sealing surface 111 and second, and lower concave part 210 comprises the first lower sealing surface 211 and the second lower sealing surface 212.For seal 400 is fitted tightly with upper recess 110 and lower concave part 210 respectively, the cross sectional shape of the seal 400 is rectangular, should be appreciated that the cross sectional shape of seal 400 is not limited to the shape of example in Fig. 2, such as seal 400 can also be T-shaped, oval etc.The height of seal 400 should be greater than the height sum of sealing surface 112 and the second lower sealing surface 212 on second, in the time that upper casing 100 and lower casing 200 are seated, seal 400 is compressed in the seal groove being combined into by upper recess 110 and lower concave part 210, by seal 400 and upper recess 110 first on sealing surface 112 on sealing surface 111 and second, and the first lower sealing surface 211 of lower concave part 210 contacts with the sealing that the second lower sealing surface 212 forms, provide sealing function.Hence one can see that, and seal 400 forms double being sealed and matched with upper recess 110, and seal 400 forms double being sealed and matched with lower concave part 210 simultaneously, thereby anti-sealing enters the enclosure interior of holding pcb board 300 effectively.It is worth mentioning that, under the effect of pcb board 300, the outside elastic dilatation of seal 400, the lateral surface of seal 400 can closely be adjacent on second on sealing surface 112 and the second lower sealing surface 212, further strengthen the sealability of seal 400, thereby stopped that extraneous water enters in housing from the fit-up gap, outside of upper casing 100 and lower casing 200.
Further, in order to keep the excellent sealing between seal 400 and upper casing 100 and lower casing 200, and the size of irrelevant hydraulic pressure, seal 400 all convexes with the protruding (not shown) circumferentially forming continuously along seal 400 towards the sealing surface of upper recess 110 and lower concave part 210, can increase thus the surface pressure of seal 400, and then improve sealing property.In preferred embodiments, this protruding cross sectional shape is curved, for example semicircle, thereby increases the surface pressure of seal 400.Further alternatively, the cross sectional shape of projection also can be triangular in shape.But, should be appreciated that according to the protruding cross sectional shape of the utility model embodiment and be not limited to circular arc or triangle.
In the present embodiment, the inner surface of seal 400 is concaved with the recess (not shown) of the edge part of accommodating pcb board 300.In a preferred embodiment, be positioned at the middle part of seal 400 for the recess of the edge part of accommodating pcb board 300, and the edge part of pcb board 300 and this recess interference fit.Thus, can location be installed to pcb board 300 on the one hand, so that pcb board 300 is fastened in housing more securely, can reduces on the other hand seal 400 and be set in the difficulty on pcb board 300, thus the efficiency of assembling of raising Waterproof electronic equipment.The part that pcb board 300 is positioned at recess can connect up, to increase the free space of pcb board 300.
It is worth mentioning that, Waterproof electronic equipment of the present utility model, upper casing 100 and/or lower casing 200 do not need to be designed for the relevant connection structure (for example double-screw bolt or buckle) of fastening pcb board 300, after upper casing 100 and lower casing 200 are seated, the elastic-restoring force of the periphery by acting on pcb board 300 can make pcb board 300 be stabilized in securely in housing, the design that not only simplifies the structure, and greatly improved the utilance in enclosure interior space; Simultaneously, pcb board 300 is pressed on seal 400, even if Waterproof electronic equipment is immersed in the water completely, and in the situation that hydraulic pressure is higher, still can keep outside the effect of good sealing, to under the position-limiting action of seal 400, can also reach more stable sealing effectiveness by pcb board 300.
These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
