Abstract
The utility model discloses a circuit board fixing structure. A circuit board is installed in a shell. The shell includes an upper shell and a lower shell. At least one elastic body is arranged between the upper shell and/or the lower shell and the circuit board. The circuit board fixing structure provided by the utility model can realizes functions of buffering and damping for the circuit board, so that damages of the circuit board caused by pressure from a shell of an electronic product are prevented.
Description
Technical field
The utility model relates to a kind of circuit board fixation structure, relates in particular to a kind of circuit board to be cushioned, and damping prevents that electronic product shell from damaging the circuit board fixation structure of circuit board to the circuit board compressing.
Background technology
Mobile phone is a kind of mobile communication equipment that communicates with each other, because its volume is little, easy to carry, and along with interpersonal productive life becomes more and more tightr, therefore, mobile phone has become the essential tool of people's daily life.
Mobile phone inside has complicated electronic devices and components, and these electronic devices and components all are installed on the very thin circuit board, and this piece circuit board is fixed in the phone housing, just can bring into play function separately after connecting by the circuit on the circuit board.Therefore, circuit board plays very important effect as the bridge of electronic devices and components, in case fracture, each electronic devices and components just lost efficacy so.As shown in Figure 1, Fig. 1 is existing circuit board fixation structure 200 schematic diagrames.Existing circuit board of mobile phone is to use screw post 202 surfaces of upper shell 201 and two surfaces up and down that lower house 203 step surfaces 204 withstand circuit board 205 to fix in the fixed form commonly used of above-below direction.The weak point of such structure is: upper and lower casing 201,203 is hard contacts with the contacting of surface of circuit board 205.Because the thickness of circuit board is all very little, when mobile phone was subjected to dropping shock, impulsive force was directly delivered on the circuit board by last lower house, and the buffering that circuit board is subjected to is not enough, therefore was very easy to rupture.And circuit board fracture in a single day, mobile phone is cisco unity malfunction just, thereby causes the anti-ability of falling of mobile phone to reduce greatly, and the repair rate of mobile phone raises, the not sale of handedness product.This problem also exists in other electronic product equally.
Therefore, need a kind of circuit board be cushioned, damping prevents electronic product shell to the circuit board compressing and the circuit board fixation structure of damage circuit board.
The utility model content
The purpose of this utility model is to provide a kind of circuit board is cushioned, and damping prevents electronic product shell to the circuit board compressing and the circuit board fixation structure of damage circuit board.
To achieve these goals, the circuit board fixation structure that the utility model provides, described circuit board is installed in the shell, and described shell comprises upper shell and lower house, and described upper shell is or/and be provided with at least one elastomer between described lower house and the described circuit board.
Preferably, described elastomer is spring, elastic caoutchouc or sponge.
Compared with prior art, because the utility model is by arranging elastomer between described shell and described circuit board, utilize elastomeric damping characteristics, can be at electronic product when for example mobile phone or notebook computer fall, prevent that its shell is because of the excessive generation distortion of impulsive force, and then to the circuit board extrusion damage of inside, make circuit board be not easy fracture, reduced the repair rate of electronic product; And because circuit board is not easy fracture, therefore, the thickness of circuit board can be done forr a short time, thereby saves the material of circuit board, has reduced production cost.

Fig. 3 is the schematic diagram of the utility model circuit board fixation structure embodiment two.
Embodiment
Be the effect that describes technology contents of the present utility model, structural feature in detail, realizes, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
As shown in Figure 2, be the embodiment one of the utility model circuit board fixation structure, described circuit board fixation structure 100 is used in the mobile phone, also can be used for other electronic products such as notebook computer.Described circuit board 1 is installed in the shell of mobile phone, and described shell comprises upper shell 2 and lower house 3, and described upper shell 2 and lower house 3 are combined to form the accommodation space 4 of sealing, and described circuit board 1 places in the described accommodation space 4.Particularly, the two ends of the inner bottom surface of described lower house 3 are provided with step surface 31, and the two ends of described circuit board 1 are carried on the described step surface 31.Be provided with two elastomers 5 between described upper shell 2 and the described circuit board 1.Two described elastomers 5 are arranged at the same side of described circuit board 1 respectively and are distributed in the two ends of this side.The inner surface that described upper shell 2 also can be fixed in the surface that described elastomer 5 can be fixed in described circuit board 1 perhaps is fixed in the surface of described circuit board 1 and the inner surface of upper shell 2 simultaneously.Described elastomer 5 is for spring, elastic caoutchouc, sponge or all other have buffering or flexible object, for example has the silk floss pad that certain thickness can reinstatement after pressing.Buffering time, described upper shell 2 by impulsive force crimp after bumper and absorbing shock effect by described elastomer 5 absorb impulsive force, and then make described circuit board 1 avoid the direct infringement of impulsive force, thereby prevent from rupturing.
As shown in Figure 3, be the embodiment two of the utility model circuit board fixation structure, the difference of present embodiment and embodiment one is, be provided with four described elastomers 5 between described shell and the described circuit board 1, described elastomer 5 is arranged between described upper shell 2 and the circuit board 1 respectively and between described lower house 3 and the circuit board 1 simultaneously.Two described elastomers 5 are arranged at a side of described circuit board 1 respectively, and are distributed in the two ends of this side, and other two described elastomers 5 are arranged at the opposite side of described circuit board 1 respectively, and are distributed in the two ends of this side.Buffering time, described upper shell 2 or lower house 3 by impulsive force crimp after by circuit board 1 both sides described elastomer 5 simultaneously bumper and absorbing shock absorb impulsive force, and then make described circuit board 1 avoid the direct infringement of impulsive force, thereby prevent fracture.
Compared with prior art, because the utility model is by arranging elastomer 5 between described shell and described circuit board 1, utilize the damping characteristics of elastomer 5, can be at electronic product when for example mobile phone or notebook computer fall, prevent that its shell is because of the excessive generation distortion of impulsive force, and then to circuit board 1 extrusion damage of inside, make circuit board 1 be not easy fracture, reduced the repair rate of electronic product; And because circuit board 1 is not easy fracture, therefore, the thickness of circuit board 1 can be done forr a short time, thereby saves the material of circuit board 1, has reduced production cost.
Above disclosed only is preferred embodiments of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of doing according to the utility model claim still belongs to the scope that the utility model is contained.
