Abstract
The utility model discloses a soft ring body capable of improving the problems of casing deformation and water and dust prevention. The soft ring body is used as a casing of an electronic device, the casing is provided with a first casing and a second casing which are mutually spliced; and at the splicing position of the first casing and the second casing, the first casing is provided with a ring-shaped receiving groove for receiving the soft ring body, and the second casing is provided with a ring-shaped flange for pressurizing the soft ring body. The soft ring body is characterized in that a groove is arranged along the soft ring body, and therefore, the soft ring body is higher in compression and lower in counterforce to enable the casing not to deform, and has the function of water and dust prevention.
Description
Technical field
The utility model is about a kind of soft ring body, refers to have higher amount of being compressed and lower reaction force especially so that shell is indeformable and have certain water proof and dust proof ability person.
Background technique
Information circulates extensively now, thereby makes the electronic equipment exploitation in a large number thereupon of circulation information, for example: the PDA Personal Digital Assistant or the audio and video player of mobile phone, tool network linking function ... Deng.Exploded view when Fig. 1 to Fig. 3 is respectively existing ring apron and shell assembling; sectional view after the sectional view of existing ring apron and existing ring apron and the shell combination; as shown in the figure; consider the assembling of electronic equipment; protection (waterproof; dustproof) and can decompose maintenance; existing electronic equipment can comprise a shell 1 and a solid ring apron 2 usually; and shell 1 can have one first housing 11 and one second housing 12 that is bonded with each other usually; and engagement positio in first housing 11 and second housing 12; first housing 11 is provided with an annular containing groove 111 with ccontaining ring apron 2; second housing 12 is provided with an annular flange flange 121 with pressurization ring apron 2; in addition; consider the cost and the weight of electronic equipment, the material of first housing 11 and second housing 12 is generally plastics.Shell 1 is divided into first housing 11 and second housing 12 can make circuit board or electrical assembly insert easily in the shell 1 when electronic equipment is assembled, existing ring apron 2 is located at the junction point of first housing 11 and second housing 12, and make ring apron 2 distortion sealing the gap of first housing 11 and second housing, 12 junction points by the pressurization of annular flange flange 121, and then anti-sealing or dust enter shell 1 interior destruction circuit board or electrical assembly via the junction point of first housing 11 and second housing 12.After first housing 11, second housing 12 make up with ring apron 2; other connection mouth of considering the assembly cost of electronic equipment and shell 1 side is (as earphone jack, USB connection mouth or charging inlet ... Deng) design, therefore usually can near four end pin places of shell 1 respectively with screw 3 with its locking to finish the assembling of electronic equipment.
Yet because existing ring apron 2 be a solid construction, the elasticity that therefore has ring apron 2 now is less, hardness is higher and not yielding.Fig. 4 is the stereogram of existing ring apron and shell combination back distortion, as shown in the figure, when first housing 11 of existing ring apron 2 and plastic material and 12 combinations of second housing, four end angles of shell 1 are owing to be respectively with screw 3 lockings, make that the compression strength of annular flange flange 121 of second housing 12 is bigger, therefore the ring apron 2 of solid construction still deformable with near the gap of the junction point 1 four ends of closed casing angle, yet, first housing 11 of plastic material and the part of second housing 12 between these screws 3, because the compression strength of the annular flange flange 121 of second housing 12 is less, therefore the ring apron 2 than the solid construction that can't pressurize makes its distortion, make the reaction force of compression strength cause the part distortion between these screws 3 of first housing 11 and second housing 12 on the contrary, and because the ring apron 2 of solid construction is not by the certain pressurizing and deformation of the annular flange flange 121 of second housing 12, therefore ring apron 2 also can't seal the gap of first housing 11 and second housing, 12 junction points really, causes water or dust to have an opportunity to enter and destroys circuit board or electrical assembly in the shell 1.
Therefore, how createing a kind of soft ring body, so that it can have higher amount of being compressed and lower reaction force, make shell indeformable and have certain water proof and dust proof ability, will be that the utility model desires actively to disclose part.
Summary of the invention
Because the disappearance of prior art, one of the utility model purpose is promptly providing a kind of soft ring body, so that it can have higher amount of being compressed and lower reaction force, makes shell indeformable and have certain water proof and dust proof ability.
For reaching above-mentioned purpose, soft ring body of the present utility model, the shell that is used for electronic equipment, this shell has first housing and second housing that is bonded with each other, engagement positio in this first housing and this second housing, this first housing is provided with annular containing groove with ccontaining this soft ring body, and this second housing is provided with annular flange flange with this soft ring body of pressurization, and this soft ring body is characterised in that: be provided with groove along this soft ring body.
By this, soft ring body of the present utility model can have the higher amount of being compressed and lower reaction force so that shell is indeformable and have a purpose of certain water proof and dust proof ability.
