Abstract
The utility model provides a waterproof and anticollision structure with a double-layer shell. The structure includes an upper cover, a lower shell and protection rings which are installed at the four corners of the outer wall of the lower shell; the lower shell adopts a double-layer structure comprising an inner side wall and an outer side wall; certain space is reserve between the inner side wall and the outer side wall; and a plurality of stiffeners are uniformly distributed between the inner side wall and the outer side wall. When the outer layer shell is subjected to the crash of an external force, the crash is buffered by the space reserved between the inner layer shell and the outer layer shell, and extrusion and damage of the structure in a device is prevented so that the anticollision capability of the shell is greatly improved and higher-level anticollision requirements can be met; waterproof performance is greatly improved and requirements of portable devices of high waterproof level can be met; and through the newly designed waterproof pot switch structure, the problem that existing pots are not waterproof is solved.
Description
Technical field
The utility model relates to a kind of guard shield structure, particularly a kind of waterproof anticollision structure that is suitable for the employing double Shell of various hand-portable terminal equipments.
Background technology
Present various hand-portable terminal equipments have the requirement of waterproof and anticollision grade usually, common waterproofing process employing increases waterproof grommet and processes between last lower house, but if the sealing ring classification of waterproof of taking common sealing means to reach is lower, can't satisfy the purpose that the portable equipment in some classification of waterproof high requirement uses; And crashproof way normally adopts additional protection circle elastomeric material to increase the cushion effect of shell, or increases thickness of shell and increase casing rigidity, perhaps adopts above-mentioned means to realize simultaneously.Simultaneously, when adopting traditional housing waterproof construction, after generally can only being set directly at outside, its key switch (the young switch of pot) is connected on the inner wiring board, do not have waterproof effect, if in wet environment, use, the young switch of pot will turn-on power, faults such as generation misoperation or button are malfunctioning, if the young switch of pot is arranged on enclosure interior, operate in outside by modes such as button connecting rods, its sensitivity then can reduce greatly again, and not only parts such as button connecting rod are fragile, the complete machine outside still needs the specialize water-proofing treatment simultaneously, and production cost is also higher.Perhaps adopt outer button to touch the middle transition key external force is delivered to the young switch of pot of enclosure interior, so outer button and transition key all to do water-proofing treatment, so the cost height, sensitivity also can reduce greatly.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of waterproof anticollision shell structure that is suitable for various hand-portable terminal equipments that can satisfy the class requirement of the high bump of high waterproof.
The utility model is achieved in that a kind of waterproof anticollision structure that adopts double Shell, comprise loam cake, lower house and install on four angles of lower house outer wall guard ring, it is characterized in that: the double-decker that described lower house adopts madial wall and lateral wall to form, be reserved with certain space between described madial wall and the lateral wall, some reinforcements equably distribute between madial wall and the lateral wall.
Also be provided with waterproof grommet between described loam cake and the lower house, offer annular groove on the lateral wall of loam cake, be set with sealing ring in the annular groove, the sidewall of described lower house is the plane, the distance of the slightly larger in diameter of described sealing ring between the sidewall of the bottom of annular groove and lower house.
The medial surface of described guard ring is provided with the opposite buckle of direction that pair of parallel arranges, leave the space between two buckles, the lateral wall of described lower house is provided be used to the through hole that passes buckle, and described two buckles are installed in the through hole and pin are installed in the space between two buckles guard ring are blocked the lateral wall that is locked at lower house.
The lateral wall of described lower house is provided with button position groove, the bottom of described button position groove is provided with elongated slot, described madial wall is provided with corresponding elongated slot, the young switch of pot is installed on the groove of described button position, extend on the internal circuit board of madial wall after the connecting line of the young switch of described pot passes elongated slot, adopt the gluing sealing in the described elongated slot.
The cross section of described sealing ring is circular or oval, and the top edge of described lower house is provided with outward extending inclined-plane or cambered surface.
The young switch of described pot comprises switching circuit and watertight composition, and the two sides, front and back of described switching circuit all is connected to watertight composition by gummed or supersonic welding.
The annular groove top of described loam cake also is provided with outside extension, and the degree of depth of described annular groove is greater than the radius of sealing ring.
Advantage of the present utility model is: by adopting the structure of double Shell, can be when outer casing be subjected to external force collision by and internal layer shell between the gap reserved as buffering, extruding and destruction between preventing from the structure of device interior carried out, improve the anticollision ability of housing greatly, can satisfy higher bump class requirement; And owing to be provided with the groove that holds sealing ring at the sidewall of loam cake, the diameter of sealing ring is arranged to be slightly larger than the distance between the sidewall of the bottom of annular groove and lower house, in use with the pressing of upper and lower casing, because having suitable elastic shrinkage and can be constrained in the groove, sealing ring can upwards not come off, can make upper and lower casing originally between the complete sealed circle in slit fill up and lasting maintenance impaction state, improved the performance of waterproof greatly, the requirement of satisfiable high classification of waterproof portable equipment; Simultaneously, owing to adopted double-deck shell structure, the thickness that causes the sidewall of housing to compare conventional housing increases, therefore the waterproof type of conventional key switch can't use accurately, therefore can be by the young construction of switch of the anti-kettle of redesign, solve the problem that the young switch of prior art pot can't waterproof.
