Description

Portable electronic equipment

Technical Field

The present invention relates to the field of electronic technologies, and in particular, to a portable electronic device with an optical transceiver function.

Background

With the development of display technology, in recent years, demands of consumers for external design and visual experience of portable electronic devices are increasing. For example, currently popular mobile phones (i.e., portable electronic devices) with ultra-narrow bezel display screens in the market reach a higher level of visual experience and design aesthetics by further expanding the area of the active display area, and are thus highly favored by consumers.

However, the all-video mobile phone claimed in the industry is only a mobile phone with an ultra-high screen ratio, but does not achieve a 100% screen ratio, and the main reason is that various electronic components are required to be arranged besides the display screen on the front surface of the smart mobile phone.

For example, current smart phones are equipped with an optical transceiver, such as a distance sensor, for automatically turning off the background light of the screen during the call of the user, and automatically turning on the background light again when the user ends the call, thereby achieving the effect of saving power.

However, since the distance sensor is usually disposed on the front surface of the mobile phone (i.e., the portable electronic device), a corresponding through hole must be disposed on the front panel of the mobile phone to expose the distance sensor, so that the normal operation of the distance sensor will necessarily affect the screen ratio of the display screen. However, the formation of the through holes increases the complexity of the panel manufacturing process, which results in an increase in production cost. In addition, the distance sensor 3 as the optical transceiver is generally directly soldered to the circuit board of the portable electronic device, but the circuit board is easily deformed by force, so that the optical transceiver is easily shifted in angle or position to reduce the overall performance or fail.

In view of this, it is an object of the present invention to improve the manufacturing process of the optical transceiver in the current portable electronic device to overcome the problems of the prior art.

Detailed Description

Other advantages and effects of the present application will become readily apparent to those skilled in the art from the following disclosure, when considered in light of the accompanying drawings, from the detailed description of the specific embodiments. The instant application may be practiced or carried out in other various embodiments. Various modifications and alterations may be made in the details of the present description based upon the various aspects and applications without departing from the spirit of the present application. In particular, the relative proportions and positions of the various elements in the drawings are exemplary only and are not representative of the actual situation in which the present application is practiced.

Referring to fig. 1 to 3, the portable electronic device 1 of the present application mainly includes a circuit substrate 11, a display screen 12, a device frame 13, an optical transceiver module 14, a waterproof gasket 15, and a bonding member 16. Wherein the device bezel 13 extends along the outer edge of the display screen 12. The device frame 13 has a frame through hole structure 131 (refer to fig. 2) for exposing a portion of the optical transceiver module 14 (please refer to the following details).

The optical transceiver module 14 is disposed between the circuit substrate 11 and the equipment frame 13, and is configured to send a first optical signal R1 to a target object 2 or receive a second optical signal R2 from the target object 2 (refer to fig. 6 to 9).

Referring to fig. 4, in one embodiment, the optical transceiver module 14 mainly includes a board connector 141, an optical component 142, an optical transceiver 143, and a positioning connector 144.

The board-end connector 141 is used for electrically connecting the circuit substrate 11.

The main body of the optical component 142 is embedded in the device frame 13, and has a first refraction surface 1421, a second refraction surface 1422 and a total reflection surface 1423 (as shown in fig. 5 to 9).

Specifically, the first refractive surface 1421 is exposed by the device via structure 131, and causes the first optical signal R1 to travel away from the device frame 13 toward the target object 2 (refer to fig. 6 and 8), or causes the second optical signal R2 to enter the device frame 13 and travel toward the optical transceiver 143 (refer to fig. 7 and 9). In this embodiment, the optical component 142 is an optical column having three end sides, and preferably, the first refractive surface 1421, the second refractive surface 14222 and the total reflection surface 14233 are respectively formed on the three end sides of the optical column 142, so as to reduce the difficulty in manufacturing the optical component 142.

The main body of the optical transceiver 143 is buried in the device frame 13 (see fig. 8 and 9). In the present embodiment, the optical component 142 further has an accommodating space 1424 for accommodating the optical transceiver 143 therein (refer to fig. 4 and 10), and the second refraction surface 1422 is disposed on a wall surface of the optical component 142 forming the accommodating space 1424 (refer to fig. 6 and 7).

The optical transceiver 143 is, for example, a distance sensor, and is configured to transmit the first optical signal R1 to the target object 2, for example, a user, or to receive the second optical signal R2 from the target object 2. Preferably, the second optical signal R2 is generated by reflection of the first optical signal R1 traveling to the target object 2, and thus, the state of the target object 2, for example, the distance or the like, can be determined from the difference between the first optical signal R1 and the second optical signal R2.

Specifically, the first optical signal R1 travels toward the second refraction surface 1422 by the optical transceiver 143, and then enters the second refraction surface 1422, and the first optical signal R1 travels toward the total reflection surface 1423 by refraction of the second refraction surface 1422. As shown in fig. 6 and 8, since the medium of the first optical signal R1 passing through the front and back of the incident second refraction surface 1422 is changed, the incident angle θ11 of the first optical signal R1 on the second refraction surface 1422 is substantially larger than the refraction angle θ12, so that the first optical signal R1 can travel toward the total reflection surface 1423 along the predetermined direction.

Then, the first optical signal R1 is incident on the total reflection surface 1423, the total reflection of the total reflection surface 1423 causes the first optical signal R1 to travel toward the first refraction surface 1421, the refraction of the first refraction surface 1421 causes the first optical signal R1 to travel toward the target object 2, the first refraction surface 1421 is exposed by the device through hole structure 131, the first optical signal R1 is caused to travel away from the body of the portable electronic device 1 toward the target object 2, and the optical transceiver 143 is caused to complete transmitting the first optical signal R1 to the target object 2. As shown in fig. 6 and 8, because the medium of the first optical signal R1 in the front-back path of the first refraction surface 1421 is changed, the incident angle θ13 of the first optical signal R1 on the first refraction surface 1421 is smaller than the refraction angle θ14, so that the first optical signal R1 can travel toward the target object 2 along the predetermined direction.

With continued reference to fig. 6 and 8, the incident angle θ1r of the first optical signal R1 on the fully reflective surface 1423 is equal to the sum of the angle α of intersection of the second refractive surface 1422 with the fully reflective surface 1423 and the refraction angle θ12 of the first optical signal R1 on the second refractive surface 1422. The angle of incidence θ13 of the first optical signal R1 on the first refractive surface 1421 is equal to the difference between the intersection angle γ of the first refractive surface 1421 with the fully reflective surface 1423 and the angle of incidence θ1r of the first optical signal R1 on the fully reflective surface 1423. Therefore, the traveling direction of the first optical signal R1 is related to the inclination angles of the first refraction surface 1421, the second refraction surface 1422 and the total reflection surface 1423, so that the first optical signal R1 can be ensured to travel toward the target object 2 in the predetermined direction and avoid the display screen 12 only by adjusting the inclination angles of the first refraction surface 1421, the second refraction surface 1422 and the total reflection surface 1423.

The second optical signal R2 travels from the target object 2 toward the first refractive surface 1421, and then enters the first refractive surface 1421, and the second optical signal R2 travels toward the total reflection surface 1423 by refraction of the first refractive surface 1421. As shown in fig. 7 and 9, since the medium of the path of the second optical signal R2 before and after entering the first refraction surface 1421 is changed, the incident angle θ24 of the second optical signal R2 on the first refraction surface 1421 is larger than the refraction angle θ23, so that the second optical signal R2 can travel toward the total reflection surface 1423 along the predetermined direction. It should be noted that, the first refraction surface 1421 is exposed by the device through hole structure 131, and makes the second optical signal R2 enter the body of the portable electronic device 1 and travel toward the optical transceiver 143, and makes the optical transceiver 143 complete receiving the second optical signal R2 from the target object 2.

Then, the second optical signal R2 enters the total reflection surface 1423, the total reflection of the total reflection surface 1423 causes the second optical signal R2 to travel toward the second refraction surface 1422, and then enters the second refraction surface 1422, the refraction of the second refraction surface 1422 causes the second optical signal R2 to travel toward the optical transceiver 143, and the optical transceiver 143 completes receiving the second optical signal R2 from the target object 2. As shown in fig. 7 and 9, because the medium of the path of the second optical signal R2 before and after entering the first refraction surface 1421 is changed, the incident angle θ22 of the second optical signal R2 on the second refraction surface 1422 is smaller than the refraction angle θ21, so that the second optical signal R2 can travel toward the optical transceiver 143 along the predetermined direction.

As shown in fig. 7 and 9, an incident angle θ2r of the second optical signal R2 on the fully reflective surface 1423 is equal to a sum of an intersection angle α of the second refractive surface 1422 and the fully reflective surface 1423 and an incident angle θ22 of the second optical signal R2 on the second refractive surface 1422. The refraction angle θ23 of the second optical signal R2 on the first refraction surface 1421 is equal to the difference between the intersection angle γ of the first refraction surface 1421 and the total reflection surface 1423 and the incident angle θ2r of the second optical signal R2 on the total reflection surface 1423. The traveling direction of the second optical signal R2 is related to the tilt angles of the first refractive surface 1421, the second refractive surface 1422 and the total reflection surface 1423, so that the second optical signal R2 can travel toward the optical transceiver 143 in a predetermined direction and avoid the display screen 12 only by adjusting the tilt angles of the first refractive surface 1421, the second refractive surface 1422 and the total reflection surface 1423.

Referring to fig. 4, 11 and 12, the positioning connector 144 is electrically connected to the optical transceiver 143, and positions the optical component 142 and the optical transceiver 143 respectively. The positioning end connector 144 is in butt joint with the board end connector 141, so that the optical transceiver 143 is electrically connected to the circuit substrate 11, so that the circuit substrate 11 sends the first optical signal R1 or sends the second optical signal R2 to the circuit substrate 11. In one embodiment, the first optical signal R1 is generated by the circuit substrate 11, and the second optical signal R2 is generated by transmitting the first optical signal R1 to the target object 2, so that the second optical signal R2 is related to the first optical signal R1.

As shown in fig. 13 to 17, in the present application, a position compensation mechanism is further designed between the positioning end connector 144 and the board end connector 141, specifically, the positioning end connector 144 has at least one positioning end conductive terminal 1441, the board end connector 141 has at least one board end conductive terminal 1411, when the positioning end connector 144 abuts against the board end connector 141, the positioning end conductive terminal 1441 electrically contacts the board end conductive terminal 1411, and at least one of the positioning end conductive terminal 1441 and the board end conductive terminal 1411 is capable of being deformed under force to force the positioning end connector 144 to maintain a predetermined position, thereby providing a positional alignment between the optical component 142 and the optical transceiver 143. In the present embodiment, the positioning end

conductive terminals

1441 and 1411 are, for example, elastic conductive terminals, so that the positioning end

conductive terminals

1441 and 1411 can provide a position compensation function, so that when the circuit substrate 11 is deformed such as warped, the positioning end connector 144 is always positioned at a predetermined position, so that the positions between the optical component 142 and the optical transceiver 143 are always aligned, and the transmission operation of the first optical signal R1 and the second optical signal R2 is ensured to be smoothly performed.

In another embodiment, the positioning terminal connector 144 includes a plurality of positioning terminal conductive terminals 1441, one end of each positioning terminal conductive terminal 1441 has a positioning terminal pad 14411 for soldering the optical transceiver 143, a plurality of positioning terminal pads 14411 are respectively disposed on a first line L1 and a second line L2 (refer to fig. 14), and the first line L1 is parallel to the second line L2, so as to facilitate the subsequent soldering operation and check whether soldering is implemented.
