Description
Technical field
The utility model relates to fixed structure, particularly relates to a kind of fixed structure for circuit board.
Background technology
At African mobile phone market, limit by the level of consumption, the mobile phone update cycle is longer, therefore higher to the waterproof of mobile phone, anticollision reliability requirement, needs can accomplish under severe bad border that quakeproof and windproof is husky, but other mobile phone firmness degrees are in the market directly proportional to manufacturing cost, are not suitable for African mobile phone market.
Utility model content
The purpose of this utility model is to provide a kind of fixed structure of cell phone mainboard, solves the technical problem of the shockproof sand-proof ability of low cost mobile phone.
The fixed structure of cell phone mainboard of the present utility model, the front end face upper, middle and lower of cell phone mainboard arranges three laying element regions respectively, fix bonding one at the edge in each laying element region and enclose elastic adhesive tape, handset shell fits tightly on elastic adhesive tape, the rear end face of cell phone mainboard lays a buffer unit fitted tightly, and buffer unit is made up of elastomeric material.
Described buffer unit comprises a central buffer block and several edge buffer stoppers, the cross sectional shape of central buffer block is square, wherein pericardium is containing a flat air bag parallel with cell phone mainboard, the cross sectional shape of edge buffer stopper is rectangle, wherein pericardium is containing a flat columniform air bag, is communicated with between the air bag of edge buffer stopper and the air bag of central buffer block by hollow tube.
In two pressure-bearing surfaces of the flat air bag of described central buffer block, a pressure-bearing surface arches upward to flat air bag center, forms arc pressure-bearing surface, another pressure-bearing surface arranges evenly distributed elastic cylinder, points to arc pressure-bearing surface.
The fixed structure of cell phone mainboard of the present utility model provides several reinforcing areas, receiver, screen and keyboard can be reinforced respectively according to respective protection feature, can effectively reduce domestic cost, utilize beam can improve overall shock resistance, improve useful life.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Accompanying drawing explanation

Fig. 2 is the side structure schematic diagram of the fixed structure of the utility model cell phone mainboard;
Fig. 3 is the structural representation of the buffer unit of the fixed structure of the utility model cell phone mainboard;
Fig. 4 is the A-A direction cutaway view of the buffer unit of the fixed structure of the utility model cell phone mainboard.
Embodiment
As shown in Figure 1, in the front end face upper, middle and lower of cell phone mainboard 01, three laying element regions are set respectively, fix bonding one at the edge in each laying element region and enclose elastic adhesive tape 02, when cell phone mainboard 01 is fixed in handset shell, handset shell front portion fits tightly on elastic adhesive tape 02.The laying element region on top is for laying loud speaker and associated circuit, the laying element region at middle part is for laying the associated circuit and processor that are connected with display screen, the laying element region of bottom is for laying the associated circuit and external interface circuit that are connected with keyboard, also the circuit on whole mainboard can not be made to damage even if a part of like this housing is impaired, be conducive to mainboard life-saving and reduce maintenance cost.
As shown in Figure 2, the rear end face of cell phone mainboard 01 lays a buffer unit fitted tightly 03, for the center of cell phone mainboard 01 and corner provide collision buffering.
As shown in Figure 3, buffer unit 03 is made up of elastomeric material (such as latex), comprise a central buffer block 04 and several edge buffer stoppers 05, the cross sectional shape of central buffer block 04 is square, wherein pericardium is containing a flat air bag parallel with cell phone mainboard 01, the cross sectional shape of edge buffer stopper 05 is rectangle, wherein pericardium is containing (cross section is an oval) flat columniform air bag (not providing in figure), is communicated with between the air bag of edge buffer stopper 05 and the air bag of central buffer block 04 by hollow tube 06.Central buffer block 04 and edge buffer stopper 05 form gasbag pressure adjusting device, for the impact of an air bag, can be distributed to other air bags in time, on the buffering basis of elastomeric material, provide better spring protective.
As shown in Figure 4, in two pressure-bearing surfaces of the flat air bag of central buffer block 04, a pressure-bearing surface arches upward to flat air bag center, forms arc pressure-bearing surface, another pressure-bearing surface is arranged evenly distributed elastic cylinder 07, points to arc pressure-bearing surface.The internal structure of flat air bag can improve collision buffering performance further, and the ductility of air bag.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that the utility model claims determine.
