As shown in fig. 1 to 5, a mobile terminal according to an embodiment of the present invention includes a mobile terminal body, where the mobile terminal body includes a housing, a screen connected to the housing, and a battery, a circuit board, and the like disposed in the housing. The mobile terminal can be a mobile phone or a tablet computer and the like. This internal light sense proximity sensor and the elastic sleeve 1 of being provided with of mobile terminal, elastic sleeve 1 has the cavity 10 that is used for supplying light sense proximity sensor embolias, and elastic sleeve 1 has certain elasticity, and buffering protective effect is good, and elastic sleeve 1 overlaps outside light sense proximity sensor to protect light sense proximity sensor, guarantee that light sense proximity sensor can work reliably. The light sensation proximity sensor comprises a visible light sensing device, a proximity light sensing device and a proximity light generating device which are adjacent. The visible light sensing device is an ambient light sensing device which automatically adjusts the brightness of screen backlight by monitoring the intensity of ambient light or controls the on and off of a key lamp; the proximity light generating device and the proximity light sensing device judge whether the mobile phone is close to the face by monitoring infrared light emitted by the proximity light generating device through the proximity light sensing device when a telephone receiver is used for communication, screen backlight can be turned off when the mobile phone is close to the face, the effect of saving electricity is achieved, and meanwhile misoperation can be prevented for a capacitive touch screen; and a plurality of proximity optical sensing devices can be used for simple gesture recognition and other applications. The proximity light generating device may be an infrared LED lamp. The distance between the centers of the proximity light sensing device and the proximity light generating device may be less than 2 mm, and the distance between the centers of the proximity light sensing device and the proximity light generating device may be 1.4 mm. Elastic sleeve 1 corresponds visible light sensing device and is close light sensing device department and be provided with first opening 101, elastic sleeve 1 is provided with second opening 102 corresponding to being close light sensing device department, first opening 101 with separate by barricade 11 between the second opening 102, like this, elastic sleeve 1 is less to the influence of light sense proximity sensor, and light sense proximity sensor's result of use is good, and the reliability of product is high, and user experience is effectual. The center-to-center distance between the first opening 101 and the second opening 102 may be less than 2 mm, and may be set to 1.4 mm, for example. The first opening 101 and the second opening 102 may be circular or rectangular.
Specifically, the size of the chamber 10 may be smaller than the external size of the light-sensitive proximity sensor, and the elastic sleeve 1 may tightly fit the light-sensitive proximity sensor, so that the protection performance is good.
In a specific application, the length of the light sensation proximity sensor can be 3.9 to 4.0 millimeters and the like, and the width can be 2.3 to 2.4 millimeters and the like; the chamber 10 may have a length of 3.6 to 3.85 mm, or the like, and a width of 2.1 to 2.25 mm, or the like. In this embodiment, the length, width and height of the light-sensitive proximity sensor are 3.94 mm, 2.36 mm and 1.35 mm, respectively, the length and width of the cavity 10 are 3.8 mm and 2.2 mm, respectively, and the elastic sleeve 1 is not easy to fall off.
Specifically, the elastic sleeve 1 can be made of dark plastic material, so that light can be easily absorbed, and the light-sensitive proximity sensor is prevented from being interfered.
In this embodiment, the elastic sleeve 1 can be made of black silica gel, and has good light absorption effect, low internal diffraction value and reliable product performance.
Specifically, the mobile terminal body is provided with a front panel, the front panel can be glass, the upper end of the elastic sleeve 1 is provided with a sealing rib 12 attached to the front panel, and the sealing rib 12 is in a closed ring shape and surrounds the peripheries of the first opening 101 and the second opening 102. The sealing rib 12 is in interference of 0.05mm when contacting with the front panel (glass), and the dustproof and waterproof effect is good. The cross-section of the sealing rib 12 may be triangular or rectangular or trapezoidal or semi-circular.
Specifically, there is a gap between the light-sensing proximity sensor and the front panel, and if the gap is not reserved, the light-sensing proximity sensor may collide with the front panel to crush the light-sensing proximity sensor or the front panel in consideration of assembly errors and the like. Because, the centre-to-centre spacing that is close light sensing device, is close light generating device is very little, and when the outside had the object to shelter from entirely, it can be through the receiving terminal (being close light sensing device) that the clearance direct access is close to light generating device (infrared lamp) transmission light just to lead to the received light intensity value very big, and inside diffraction value is very big promptly. When the greasy dirt on the face of a user is serious, the greasy dirt can be stuck to the position, corresponding to the light-sensitive proximity sensor, of the front panel during calling, the greasy dirt can play a role in blocking objects, diffraction values are large, light intensity values are large, under the condition, the approaching state can be automatically judged, and the mobile phone is in a state that the screen is not bright. The problem of oil stain is solved. Moreover, through simulation experiments, the infrared ray diffraction between the two holes of the first opening 101 and the second opening 102 is the strongest, and the black retaining wall 11 is arranged to easily absorb the infrared ray; the wall 11 has a proper width to block the transmitting hole and the receiving hole (i.e., the proximity light generating device and the proximity light sensing device), and the wall 11 has a proper height not to be flush with the dustproof and waterproof sealing rib 12, and the wall 11 is lower than the upper end of the sealing rib 12.
Specifically, the thickness of barricade 11 can be less than the wall thickness of elastic sleeve 1, and some users' hair is comparatively scattered, and black hair absorbs light easily, leads to being close to that the infrared light that light generating device (transmitting terminal) sent out is all absorbed, does not reflect back, so even when the cell-phone is close to the face, the cell-phone also probably judges to be the bright screen when keeping away from the state promptly answering the phone. By thinning the thickness of the middle retaining wall 11, the light is intentionally diffracted, even if the internal diffraction is large when the black hair approaches, the approach state can still be judged, and the user experience effect is good.
Specifically, one side integrated into one piece of elastic sleeve 1 has prevents slow-witted bellying 13 or prevents slow-witted depressed part, is provided with corresponding cooperation structure (the depressed part or the bellying that correspond) in the mobile terminal to install elastic sleeve 1 through unsmooth complex mode. When the mobile terminal is assembled, the elastic sleeve 1 is generally manually installed on a circuit board on which the light sensation proximity sensor is already adhered, at the moment, the light sensation proximity sensor is rectangular, the left side and the right side are difficult to distinguish, and particularly, under the condition of large quantity, the manual work is difficult to avoid making mistakes. Through having the fool-proof convex part 13 or the fool-proof concave part at one side integrated into one piece of elastic sleeve 1, can improve assembly efficiency.
The embodiment of the invention also provides an elastic sleeve 1 sleeved on the light sensation proximity sensor in the mobile terminal, the elastic sleeve 1 is provided with a chamber 10 for the light sensation proximity sensor to be sleeved, the elastic sleeve 1 is provided with a first opening 101 corresponding to the visible light sensing device and the proximity light sensing device in the light sensation proximity sensor, the elastic sleeve 1 is provided with a second opening 102 corresponding to the proximity light generating device in the light sensation proximity sensor, and the first opening 101 and the second opening 102 are separated by a retaining wall 11.
