Abstract

The invention relates to an electronic device structure which comprises an upper casing body, a lower casing body, a mainboard, a suspending element and a fixing element, wherein the upper casing body and the lower casing body are separately provided with an upper binding post and a lower binding post correspondingly. The mainboard is arranged between the upper casing body and the lower casing body, and is provided with a through hole. The upper binding post penetrates through the through hole, the size of the through hole is greater than that of the upper binding post, and then a gap is formed between the upper binding post and the through hole. The suspending element is arranged between the mainboard and the lower casing body, and is combined with one side of the mainboard, and a suspending space is formed between the suspending element and the mainboard. The fixing element penetrates through the lower binding post and the suspending element, and is fixed on the upper binding post, and then the mainboard is arranged on the lower binding post by the suspending element. In the invention, the movable space and the suspending space generated by the size matching of the through hole and the upper binding post and the arrangement of the suspending element are utilized to ensure that the mainboard has displacement in three axis directions, thereby good buffer capability is provided, and the deformation or damage of the mainboard caused by external force impact or stress is avoided.

Description

Electronic device construction

Technical field

The present invention particularly can be towards the electronic device construction of three direction of principal axis displacements about a kind of motherboard about a kind of electronic installation.

Background technology

Development in science and technology is quick now, computer equipment has become in the work or indispensable product in the life, and the development trend of the electronic product compact product towards microminiaturization is is gradually researched and developed, concerning the user that frequent needs move outside, as notebook computer portable electronic products such as (Notebook) become more portable, significantly promoted the convenience of using.Notebook computer inside must be equipped with a motherboard, with the core component as computer system, is able to carry out smoothly the preset function of the peripheral hardware that electrically connects with motherboard.

The mode of at present common fixed host computer plate is that the lower house at notebook computer device is provided with a plurality of conduction copper columns (boss) as fixed component, and motherboard offers a plurality of through holes corresponding to the copper post.Motherboard is put on the copper post, and and lower house between keep a suitable spacing, wore the through hole of motherboard more respectively by a plurality of bolts, and be locked on the copper post, make motherboard produce an effect of suspending by the copper post, avoid the leg contact at the motherboard back side directly to contact and cause short circuit, at last upper shell is incorporated into lower house with housing, and with motherboard and two housings claw up and down together.

Mode with the sealed fixed host computer plate of copper post commonly used though motherboard can be fixed in firmly up and down between the two housings, because motherboard directly is contacted with housing, therefore lacks the design of buffering.When notebook computer is collided or drops ground, the electronics spare part that electrically is arranged on the motherboard will produce damage because of bump, or cause the fracture that sets firmly the position and cause problems such as motherboard displacement.

In order to solve the above problems, patent No. 576515 patent case in Taiwan discloses a kind of motherboard stationary installation, replaces screw fixed host computer plate with the flexible latch of tool, the surge capability when being impacted so as to increasing motherboard.Though No. 576515 the patent case provides motherboard good surge capability, latch easily causes looseningly because of material aging after long-time the use, and it sets firmly effect and be good not as what will come with the effect of screw locking.

Particularly at ball bar array encapsulation (Ball Grid Array, BGA) motherboard, no matter be with screw locking motherboard or with fixed forms such as latch fixed host computer plates, when screw locking or latch is inserted in the pin hole, motherboard is with the fixing of coping screw or latch and the displacement (being the direction of X-axis and Y-axis) that can't produce horizontal direction, therefore the stress that motherboard bore can only produce distortion towards vertical direction (being Z-direction), so will cause the ball gird array packaging structure of motherboard to be destroyed, cause the effect that forfeiture electrically connects between chip and the motherboard.

Summary of the invention

In view of above problem, the invention provides a kind of electronic device construction, lack buffering so as to the fixed form that improves motherboard commonly used, and then cause motherboard to be destroyed and lose the problem of electric connection effect.

Electronic device construction of the present invention includes a upper shell, a lower house, a motherboard, suspend part, an and fixture.Upper shell one side is provided with column on, and upward column has a fixed orifice, and lower house is provided with column corresponding to a side of upper shell, and column has a perforation down.Motherboard is arranged between upper shell and the lower house, and motherboard has a through hole and a plurality of engagement groove, and last column wore through hole, and clear size of opening has mobile space greater than the size of last column so that go up between column and the through hole.

The part that suspends is arranged between motherboard and the lower house, the two outstanding wings that the part that suspends has a joint portion and extends from the joint portion, the joint portion is resisted against down column, and the joint portion has a combined hole, and at least one second deformation section that the two outstanding wings have one first deformation section respectively and extend from first deformation section, thereby possessing the characteristic of elastic deformation, the second deformation section build-in is in the engagement groove of motherboard, so that a joint portion and motherboard suspension spacing at interval.Fixture wore the perforation of column down and the combined hole of the part that suspends, and was fixed in the fixed orifice of column, was arranged at down column by suspending part to make motherboard.

Beneficial effect of the present invention is, the mobile space and the suspension spacing that are produced by being provided with of the size match of through hole and last column and the part that suspends, make motherboard possess three axial displacements, thereby possess good surge capability, avoid motherboard to produce distortion or destroy because of external force collision or stress.

Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
