Description

Mobile terminal

Technical Field

The invention relates to the technical field of communication equipment, in particular to a mobile terminal.

Background

With the continuous development of the mobile terminal industry, the lightness and thinness of the mobile terminal has become one of the important determining factors of the product competitiveness. The camera module is usually arranged along the thickness direction of the mobile terminal, so that the camera module occupies the space in the thickness direction of the mobile terminal, and further the lightness and thinness of the mobile terminal are affected.

As shown in fig. 1, in a conventional mobile terminal, an avoiding hole 111 is formed in a rear cover 110, a camera body 120 is located at the avoiding hole 111, a decorative ring 130 is disposed around the camera body 120, a camera lens 140 is mounted inside the decorative ring 130, and the camera body 120 is located below the camera lens 140.

The above structure has the following drawbacks:

a. since the decorative ring 130 has a certain width, specifically, as shown in fig. 1, a distance L between the top of the camera body 120 and the avoidance hole 111 is L1+ L2+ L3, where L1 is a distance between the top of the camera body 120 and an inner side of the decorative ring 130, L2 is a distance between an inner side of the decorative ring 130 and an edge of the camera lens 140, and L3 is a distance between an edge of the camera lens 140 and an outer side of the decorative ring 130. Therefore, the bezel 130 may be cumbersome in appearance, resulting in a poor user experience of the mobile terminal.

b. The outer side of the bezel 130 is typically chamfered to provide a better tactile feel to the bezel 130. However, the width of the decoration ring 130 needs to be set as small as possible, so that the chamfering amplitude of the outer side surface of the decoration ring 130 is limited, the touch feeling of the mobile terminal is still not ideal, and the user experience is poor.

c. Currently, some mobile terminals have a rear cover 110 made of glass, and a bezel 130 is usually made of metal, which may generate a split feeling in appearance, so that the user experience of the mobile terminal is poor.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 2 and fig. 3, an embodiment of the present invention discloses a mobile terminal, which includes a housing and a camera, where the camera includes a circuit board, a photosensitive device disposed on the circuit board, a lens group disposed above the photosensitive device, and a camera lens 220 disposed above the lens group, the circuit board, the photosensitive device, the lens group, and other structures form a camera body 210, and the camera lens 220 is located above the camera body 210. The housing is a carrying component of the mobile terminal, and specifically includes a main board upper cover bracket 230 and a rear cover 240 disposed opposite to the main board upper cover bracket 230. The camera body 210 may have a circular structure, and is disposed on the main board upper cover bracket 230. Offer the hole 241 of dodging on the back lid 240, should dodge the hole 241 and can set up to the round hole, and one side of it is used for preventing camera body 210 and back lid 240 to interfere, and on the other hand supplies the light among the external environment to get into in the camera body 210. The camera lens 220 is used for blocking the avoiding hole 241 to prevent impurities such as dust and liquid in the external environment from entering the mobile terminal, and the camera lens 220 can be directly adhered to the rear cover 240 and covers the avoiding hole 241. The camera lens 220 and the rear cover 240 may be aligned by using a CCD (Charge-coupled Device) to ensure that the center line of the camera lens 220 is aligned with the optical axis of the camera body 210 (i.e., the optical axis of the lens group).

In addition, the mobile terminal may further include a cradle 250, the rear cover 240 may be disposed on the cradle 250, and a buffer foam 260 may be disposed between the cradle 250 and the camera body 210.

In the mobile terminal disclosed in the embodiment of the present invention, the camera lens 220 is directly adhered to the rear cover 240, so that the mobile terminal can cancel a decorative ring in a conventional mobile terminal, so that the structure of the camera lens 220 is simpler and more flexible, and the user experience is further improved. As shown in fig. 2, a distance L1 between the top of the camera body 210 and the avoiding hole 241 is significantly smaller than the sum of L1, L2 and L3 in fig. 1. And, after cancelling and decorating the circle, the spare part quantity that mobile terminal contains reduces to some extent, and its processing cost reduces thereupon, and processing technology is simpler.

When a user uses the mobile terminal, the user often touches the camera lens 220, and therefore, in order to improve the tactile sensation of the camera lens 220, an annular chamfered surface 221 may be provided at an edge of one side of the camera lens 220 facing away from the camera body 210. The annular chamfered surface 221 may be formed by a chamfering process, and may specifically be a conical surface, and the cross-sectional shape of the camera lens 220 at the annular chamfered surface 221 is a straight line, or may also be an arc-shaped curved surface, that is, the cross-sectional shape of the camera lens 220 at the annular chamfered surface 221 is an arc line. When the annular chamfer surface 221 is a conical surface, the transition between the rear cover 240 and the camera lens 220 is more gradual, and the abrupt feeling caused by the height difference is relieved, so that the camera lens 220 has better touch feeling, and meanwhile, the processing process of the conical surface is simpler, so that the annular chamfer surface 221 is set as the conical surface in the embodiment of the invention.

Since the size of the camera lens 220 is large, the limitation on processing the annular chamfered surface 221 is less, and the size of the annular chamfered surface 221 can be flexibly set based on the requirement of improving the user experience. Specifically, in the radial direction (i.e., the X direction in fig. 2) of the camera lens 220, the distance between the inner edge and the outer edge of the annular chamfered surface 221 is the width W of the annular chamfered surface 221, which may be preferably greater than 1mm, so that a better tactile sensation at the annular chamfered surface 221 may be obtained, which in turn improves the user experience.

In a further embodiment, the thickness T of the camera lens 220 at the outer edge of the annular chamfered surface 221 is greater than 0.1mm, thereby further improving the user experience.

Optionally, in the optical axis direction (i.e., Y direction in fig. 2) of the camera body 210, the inner edge of the annular chamfered surface 221 is aligned with the hole wall of the relief hole 241. The arrangement can improve the touch feeling of the camera lens 220 and prevent the annular chamfered surface 221 from influencing the propagation path of light rays in the external environment, thereby ensuring the normal operation of the camera body 210.

In the embodiment of the present invention, the camera lens 220 is directly adhered to the rear cover 240, so that an adhesion layer 270 is formed between the camera lens 220 and the rear cover 240. The adhesive layer 270 may be a glue layer, and the thickness thereof may be set to 0.02mm, and the width thereof in the radial direction of the camera lens 220 may be 0.05 mm. In order to prevent the adhesive layer 270 from overflowing and being exposed relative to the camera lens 220, the embodiment of the invention preferably allows the adhesive layer 270 to shrink inward relative to the camera lens 220, so as to improve the appearance quality of the mobile terminal. That is, in the optical axis direction of the camera body 210, the projection surface contour line of the camera lens 220 surrounds the projection surface outer contour line of the adhesive layer 270.

When the inward shrinkage of the adhesive layer 270 relative to the camera lens 220 is too large, the adhesive area between the adhesive layer 270 and the camera lens 220 and between the adhesive layer and the rear cover 240 is small, which is not favorable for the camera lens 220 to be reliably adhered to the rear cover 240; when the amount of retraction of the adhesive layer 270 relative to the camera lens 220 is too small, the adhesive layer 270 may easily overflow. Accordingly, in the embodiment of the present invention, in the optical axis direction of the camera body 210, the distance between the contour line of the projection surface of the camera lens 220 and the outer contour line of the projection surface of the adhesive layer 270 is 0.05 to 0.2 mm.

In order to meet the appearance requirements of the mobile terminal for the user, the rear cover 240 may be configured as a glass rear cover. At this moment, the camera lens 220 can be set as a gem lens or a glass lens, so that the appearance color of the rear cover 240 and the camera lens 220 is kept consistent, and the user experience is further improved. When a gem lens is used, the thickness of the camera lens 220 can be set to 0.3 mm; when a glass lens is used, the thickness of the camera lens 220 may be set to 0.4mm or 0.5 mm.

The mobile terminal disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader, a game machine, a learning machine or a wearable device. Of course, the mobile terminal may also be other terminal devices, which is not limited in this embodiment of the present invention.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art.
