  • the outer side of the decorative ring 130 is usually chamfered, so that the touch of the decorative ring 130 is better.
  • the width of the decorative ring 130 needs to be set as small as possible. Therefore, the chamfering width of the outer side of the decorative ring 130 is limited, so that the touch feeling of the mobile terminal is still not ideal, and the user experience is poor.
  • the rear cover 110 of some mobile terminals is made of glass, and the decoration ring 130 is usually made of a metal material, which will cause a crack in appearance and make the user experience of the mobile terminal poor.
  • Embodiments of the present disclosure provide a mobile terminal to improve user experience.
  • a mobile terminal includes a housing and a camera, 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 disposed above the lens group
  • the housing includes a back cover, the back cover defines an escape hole, and the camera lens is adhered to the back cover and covers the escape hole.
  • the camera lens is directly adhered to the back cover, thereby eliminating the decorative ring in the mobile terminal in the related art, so that the structure at the camera lens is simpler and more dexterous, thereby improving the user experience.

  • the camera body 210 may adopt a circular structure, which is disposed on the motherboard cover bracket 230.
  • the rear cover 240 defines an escape hole 241, which can be set as a round hole. On the one hand, it is used to prevent the camera body 210 from interfering with the rear cover 240. On the other hand, light from the external environment enters the camera body 210.
  • the function of the camera lens 220 is to block the escape hole 241 to prevent dust, liquid and other impurities in the external environment from entering the interior of the mobile terminal.
  • the camera lens 220 can be directly adhered to the back cover 240 and cover the escape hole 241.
  • the camera lens 220 and the back cover 240 can be aligned with a charge-coupled device (Charge-coupled Device, CCD) to ensure that the center line of the camera lens 220 is aligned with the optical axis of the camera body 210 (that is, the optical axis of the lens group).

  • the cross-sectional shape at the circular chamfered surface 221 is an arc.
  • the transition between the back cover 240 and the camera lens 220 is smoother, alleviating the abruptness caused by the height difference, making the camera lens 220 feel better, and the processing technology of the tapered surface is more It is simple, so the embodiment of the present disclosure sets the circular chamfered surface 221 as a tapered surface.
  • the processing of the circular chamfered surface 221 is less restricted, so the size of the circular chamfered surface 221 can be flexibly set based on the needs of improving user experience.
  • 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, and the width W It may optionally be greater than 1 mm, so that a better touch can be obtained at the circular chamfered surface 221, which in turn improves the user experience.

  • the inner edge of the annular chamfered surface 221 is aligned with the hole wall of the escape hole 241. This arrangement not only improves the tactile feel of the camera lens 220, but also prevents the circular chamfered surface 221 from affecting the light propagation path in the external environment, thereby ensuring the normal operation of the camera body 210.
  • the camera lens 220 is directly adhered to the rear cover 240, so an adhesive layer 270 will be formed between the camera lens 220 and the rear cover 240.
