Description

A shock-absorbing sealing structure for mobile phone camera

technical field

The utility model relates to the technical field of mobile phone terminal camera systems, in particular to a shock-absorbing sealing structure for a mobile phone camera, in particular to its mechanical sealing structure.

Background technique

In the existing mobile phone camera system, in order to fully avoid the viewing angle of the camera, the openings of the back shell and the camera decoration will be opened very large. If the opening of the back shell is large, the sealing foam of the camera will be reduced, so The pressing area between the foam and the camera module will also be reduced, causing the risk of dust entering the camera, and the opening of the camera decoration is large. When the user sees through the lens, it is easy to see the rear case, especially the color of the rear case is white. Or other bright color schemes, the visual effect will be worse.

In the existing mobile phone camera system, in order to ensure that the rear shell is not exposed and the sealing foam of the camera is wide enough, the opening of the shell will be opened very small, so that the viewing angle of the camera is easily blocked, resulting in poor photo effect. A high camera will inevitably require the external camera decoration to be heightened, which will also make the appearance ugly and affect the feel and visual effect of the whole phone.

Utility model content

The purpose of this utility model is to provide a shock-absorbing and sealing structure for mobile phone camera, which uses EVA material as the shock-proof buffer part of the mobile phone camera decoration, effectively prevents the vibration of the camera lens, and uses the camera sealing rubber sleeve to replace the existing The camera foam not only solves the conflict between the size of the opening of the housing and the viewing angle of the camera, but also effectively seals the camera, ensuring that the housing will not leak from the visual point of view, and overcomes the shortcomings and deficiencies in the prior art.

In order to achieve the above object, the technical solution of the present utility model is: a shock-absorbing and sealing structure for a mobile phone camera, which includes a camera decoration and a rear shell, and the lower end of the ring-shaped camera decoration is embedded in the upper surface of the rear shell. It is characterized in that: the ring-shaped camera decoration part is bonded by the upper ring-shaped polycarbonate layer and the lower ring-shaped EVA buffer shock-absorbing layer, and a camera sealing rubber sleeve is embedded in the ring center of the camera decoration part, A lens is arranged on the upper end surface of the sealing rubber sleeve of the camera, and a camera module is arranged on the lower end surface of the sealing rubber sleeve of the camera.

The utility model discloses a shock-absorbing sealing structure for a mobile phone camera. The shock-absorbing structure adopts a shock-absorbing ring made of EVA as a shock-proof buffer part of a mobile phone camera decoration to effectively prevent the vibration of the camera lens. The sealing structure uses a camera After the sealing rubber sleeve replaces the original camera sealing foam, it not only solves the conflict between the size of the opening of the housing and the viewing angle of the camera, but also effectively seals the camera, ensuring that the housing will not leak from the visual point of view. In addition, it is worth mentioning that the internal shape of the camera sealing rubber sleeve can be used arbitrarily. According to the needs of customers, different appearance effects can be changed, so that the appearance of the same camera can be changed, which is very beautiful.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

The utility model discloses a shock-absorbing and sealing structure for a camera of a mobile phone, which comprises a camera decorative part 1 and a rear shell 2. The lower end of the ring-shaped camera decorative part 1 is embedded in the upper surface of the rear shell 2, which is different from the existing The technology is: the ring-shaped camera head decoration 1 is bonded by an upper ring-shaped polycarbonate layer 101 and a lower ring-shaped EVA buffer shock-absorbing layer 102, (EVA is an ethylene-vinyl acetate copolymer with Extremely high flexibility, EVA resin as the main component is hot melt adhesive), a camera sealing rubber sleeve 3 is embedded in the ring center of the camera decoration 1, the upper end of the camera sealing rubber sleeve 3 is provided with a lens 4, the camera sealing rubber sleeve 3. A camera module 5 is provided on the lower end surface.

In a specific implementation, the inner cavity of the camera sealing rubber sleeve 3 is in the shape of an inverted truncated cone, the diameter of the upper part is larger than the diameter of the lower part, and the inner wall of the inverted truncated cone forms annular steps distributed laterally.

During specific implementation, the outer edge of the lower end surface of the camera sealing rubber sleeve 3 forms an annular step 6. The lower surface of the rear shell 2 forms a reverse annular step 7 matched with the annular step 6 .

In specific implementation, the material of the camera sealing rubber sleeve 3 is RUBBER (synthetic rubber; rubber) or TPU (abbreviation of Thermoplastic Urethane, the Chinese name is thermoplastic polyurethane elastomer), mold compression molding and injection molding. The hardness is around 60-80 degrees.

In the specific implementation, the bottom surface of the camera sealing rubber sleeve and the camera module are pre-pressed by 0.1-0.2mm to ensure a certain degree of sealing. The gap between the end surface of the camera sealing rubber sleeve and the lens is 0mm, so that it can be sealed without jacking up the camera lens , The internal shape of the camera sealing rubber sleeve can be defined according to the ID effect, but it must be umbrella-shaped, so as to ensure that the viewing angle of the camera will not be blocked.

In actual implementation, the fit between the camera head and the back shell is zero fit or interference fit, but the back shell needs to guide the C angle. This can not only ensure the convenience of assembly, but also make it difficult for the glue to fall off after being installed on the back shell.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is limited to the above descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
