Description

Technical Field

[0001] The present invention relates to a portable electronic device, and in particular to a portable electronic device with an optical communication module. Background Art

[0002] Light Fidelity (LiFi) refers to the use of visible light communication technology to transmit information. For example, a visible light source, such as a light bulb, is used as a signal transmitter. A controller turns the light on and off, thereby controlling communication between the signal transmitter and the terminal receiver. In existing technologies, optical communication modules are embedded within portable electronic devices, and the light receiving intensity of the optical communication module is easily limited by the portable electronic device's casing.

[0003] In order to reduce the impact on the light receiving efficiency of the optical communication module, the area of ​​the optical communication module is generally increased to increase the light receiving area. However, this also increases the size of the portable electronic device, which is not conducive to the trend of thinner and lighter designs. Summary of the Invention

[0004] The present invention mainly provides a portable electronic device to solve the technical problem that the optical communication module of the existing portable electronic device is easily affected by the limited receiving position and angle, which affects the light receiving intensity.

[0005] To address the aforementioned technical issues, one of the technical solutions employed by the present invention is to provide a portable electronic device comprising a device body, a light emitting module, a light receiving module, and at least one transparent cover. The light emitting module and the light receiving module are disposed within the device body and protrude from a surface of the device body. The at least one transparent cover covers the light emitting module and the light receiving module.

[0006] The portable electronic device provided by the present invention can improve the light transmission / reception efficiency of the light transmission module and the light reception module without increasing the size of the portable electronic device through the structural design of the light transmission module and the light reception module protruding from the surface of the device body.

[0016] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components, these components should not be limited by these terms. These terms are primarily used to distinguish one component from another. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, depending on the actual situation.

[0017] First embodiment

[0018] refer to Figures 1 to 3 As shown, Figure 1 is a three-dimensional schematic diagram of a portable electronic device according to a first embodiment of the present invention. Figure 2 is a side view schematic diagram of a portable electronic device according to a first embodiment of the present invention. Figure 3 for Figure 1FIG1 is a cross-sectional diagram of a device D taken along section III-III. A first embodiment of the present invention provides a portable electronic device D comprising a device body 1, a light emitting module 2, a light receiving module 3, and at least one transparent cover 4. The light emitting module 2, the light receiving module 3, and the at least one transparent cover 4 are disposed within the device body 1. Specifically, the device body 1 comprises a display body 11 and a rotatable assembly 12, which is pivotally connected to the display body 11 so as to be rotatable relative to the display body 11. For example, the display body 11 is a tablet computer, and the rotatable assembly 12 is a rotatable handle mounted on one side of the tablet computer.

[0019] like Figure 1 and Figure 3 As shown, the rotatable component 12 has a first surface 121 and a second surface 122 relative to each other, and the light emitting module 2, the light receiving module 3 and the at least one transparent cover 4 are arranged on the rotatable component 12. The light emitting module 2 and the light receiving module 3 protrude from the first surface 121 of the rotatable component 12. The present invention can use the light emitting module 2 and the light receiving module 3 to communicate using LiFi technology. At least one transparent cover 4 covers the light emitting module 2 and the light receiving module 3. For example, at least one transparent cover 4 is a three-dimensional light cover with a curved surface contour shape, so as to maximize the light receiving area of ​​the transparent cover 4 and improve the light receiving intensity of the light receiving module 3. Therefore, when the light from the external environment is incident on the at least one transparent cover 4 from different directions, it can be completely received by the light receiving module 3, further improving the light receiving intensity. Furthermore, by designing the transparent cover 4 with a surface curvature close to or equal to that of a sphere, the present invention allows light from all directions to enter the cover perpendicular to the surface and be fully received by the light receiving module 3, thereby minimizing the possibility of light entering the transparent cover being partially refracted or reflected by the surface. Furthermore, the present invention is not limited by the material of the at least one transparent cover 4. For example, the at least one transparent cover 4 is designed to allow infrared light with a wavelength of 850 nm or greater to pass through.

[0020] In the prior art, the light emitting module and the light receiving module are installed inside the device body and are not exposed to the outside. Therefore, the light transmission / reception efficiency of the light emitting module and the light receiving module is easily limited by the device body casing. In contrast, the portable electronic device D of the present invention is designed with the light emitting module 2 and the light receiving module 3 protruding from the device body 1. This ensures that the light emitting module 2 and the light receiving module 3 are not blocked by the device body 1 casing when transmitting / receiving light.

[0021] In addition, if Figure 1 and Figure 2As shown, the display body 11 has a third surface 111 and a fourth surface 112 facing each other, and the screen M of the display body 11 is located on the third surface 111. The first surface 121 and the second surface 122 are separated by a first distance H1, and the third surface 111 and the fourth surface 112 are separated by a second distance H2. The first distance H1 is smaller than the second distance H2, i.e., the thickness of the rotatable component 12 is smaller than the thickness of the display body 11. Because the conventional light emitting module and light receiving module are installed in the device body, such as inside the handle, the size of the handle (e.g., thickness or volume) will inevitably increase, making it difficult for the user to hold the handle stably. In contrast, the light emitting module 2 and the light receiving module of the present invention protrude from the rotatable component 12 (i.e., the handle) of the device body 1, so the size of the rotatable component 12 can be further reduced, allowing the user to hold it with a more comfortable gesture.

[0022] like Figure 3 As shown, the height of the light receiving module 3 is greater than that of the light transmitting module 2. Furthermore, the height H3 of the light receiving module 3 protruding from the first surface 121 of the rotatable assembly 12 is greater than the height H4 of the light transmitting module 2 protruding from the first surface 121 of the rotatable assembly 12. Height H3 is equal to the vertical distance between the highest point 3T of the light receiving module 3 and the first surface 121. Height H4 is equal to the vertical distance between the highest point 2T of the light transmitting module 2 and the first surface 121. Furthermore, a distance GP is defined between the portion of the light receiving module 3 protruding from the first surface 121 of the rotatable assembly 12 and the portion of the light transmitting module 2 protruding from the first surface 121. This distance GP is greater than or equal to the height H3. By designing the distance GP to be greater than or equal to the height H3, the present invention ensures a sufficient distance between the light transmitting modules 2 and 3, ensuring that they operate without interference. More specifically, light emitted by the light transmitting module 2 is not blocked by the light transmitting module 3, and light entering the light transmitting module 3 from the external environment is not blocked by the light transmitting module 2.

[0023] Second embodiment

[0024] refer to Figure 4 and Figure 5 As shown, Figure 4 is a three-dimensional schematic diagram of a portable electronic device according to a second embodiment of the present invention. Figure 5It is a cross-sectional schematic diagram of the rotatable component of the second embodiment of the present invention. The second embodiment of the present invention provides another portable electronic device D, which includes a device body 1, a light emitting module 2, a light receiving module 3 and at least one transparent cover 4. The portable electronic device D provided by the second embodiment has a structure similar to that of the first embodiment, and the similarities are not repeated here. The difference is that in the portable electronic device D of the second embodiment, the at least one transparent cover 4 includes a first transparent cover 41 and a second transparent cover 42, which cover the light receiving module 3 and the light emitting module 2 respectively. For example, the first transparent cover 41 and the second transparent cover 42 are hemispherical. The hemispherical structural design of the first transparent cover 41 can maximize the light receiving area of ​​the transparent cover, thereby improving the light emission intensity of the light emitting module and the light receiving intensity of the light receiving module 3.

[0025] Furthermore, the surface curvatures of the first transparent cover 41 and the second transparent cover 42 can each be close to or equal to the curvature of a sphere. Therefore, when ambient light enters the first transparent cover 41 from different directions, it can enter the cover perpendicular to the surface and be completely received by the light receiving module 3, minimizing the risk of partial refraction or reflection of the incident light from the transparent cover.

[0026] Similarly, in the second embodiment, the distance between the portion of the light receiving module 3 protruding from the first surface 121 and the portion of the light transmitting module 2 protruding from the first surface 121 is greater than or equal to the height of the light receiving module 3 protruding from the first surface 121. Therefore, the light transmitting module 2 and the light receiving module 3 are separated by a sufficiently large distance so that they will not interfere with each other during their respective operations.

[0027] In addition, the first and second embodiments of the present invention ( Figure 1 and Figure 4 ) of the portable electronic device D further includes a first pivotal member 61 and a second pivotal member 62. Figure 4 and Figure 5 ), for example, a first pivot member 61 and a second pivot member 62 are respectively disposed on either side of the rotatable assembly 12. The first pivot member 61 and the second pivot member 62 are used to connect the display body 11 and the rotatable assembly 12. The first pivot member 61 includes a first housing 611 and a first rotation shaft 612. The first rotation shaft 612 is rotatably connected between the rotatable assembly 12 and the first housing 611, and the first housing 611 is disposed on the display body 11. The second pivot member 62 includes a second housing 621 and a second rotation shaft 622. The second housing 621 is disposed on the display body 11, and the second rotation shaft 622 is rotatably connected between the rotatable assembly 12 and the second housing 621.

[0028] Therefore, the rotatable component 12 can rotate relative to the first housing 611 and the second housing 621 about the first rotation axis 612 and the second rotation axis 622. Furthermore, the rotatable component 12 can rotate axially about an axis L1, which is the axis of the handle (rotatable component 12), that is, the line connecting the first rotation axis 612 and the second rotation axis 622.

[0029] The center line L2 connecting the light emitting module 2 and the light receiving module 3 is parallel to the axis L1. Therefore, when the handle (rotatable component 12) is rotated, the rotation angles of the light emitting module 2 and the light receiving module 3 are the same. Since the illumination of a light source is proportional to the brightness of the light source and inversely proportional to the square of the distance, if the transmission distance of the light emitting module 2 and the receiving distance of the light receiving module 3 are inconsistent, the strength of the transmitted and received signals will be affected. Therefore, the present invention makes the transmission distance of the light emitting module 2 and the receiving distance of the light receiving module 3 basically the same by designing the light emitting module 2 and the light receiving module 3 to have the same rotation angle, so that the transmission power of the light emitting module 2 and the receiving power of the light receiving module 3 can be consistent.

[0030] refer to Figure 6 and Figure 7 As shown, Figure 6 is a schematic diagram of a first housing of a portable electronic device of the present invention, Figure 7 This is a schematic diagram of the back of the portable electronic device of the present invention. In detail, the shape of the first shell 611 is different from that of the second shell 621. The first shell 611 includes a head 611A and a trunk 611B. The head 611A has a through hole C for the first shaft 612 to be inserted. The trunk 611B is the portion of the first shell 611 used to connect to the display body 11. The internal space of the trunk 611B is interconnected with the internal space of the display body 11 for the passage of wires for signal transmission. It should be noted that the second shell 621 also has a through hole similar to the first shell 611 for the insertion of the second shaft 622, but the second shell 621 does not have space for the passage of wires. The present invention divides the first shell 611 into a head 611A and a trunk 611B, so that the first shaft 612 is inserted into the through hole C of the head 611A, and the interior of the trunk 611B can have sufficient space to accommodate other components.

[0031] The display body 11 further includes a control circuit board 5, and the interior of the rotatable component 12 further includes a circuit board. The control circuit board 5 is electrically connected to the circuit board 13 inside the rotatable component 12 via at least one wire W. In the first and second embodiments of the present invention, the light receiving module 3 and the light transmitting module 2 are both disposed on the circuit board 13 and electrically connected to the circuit board 13. Figure 7As shown, the route of at least one wire W is indicated by a dashed line. Specifically, one end of the at least one wire W is electrically connected to the control circuit board 5 within the display body 11. The control circuit board 5 can be, for example, a central processing unit (CPU) or a network interface card, but the present invention is not limited thereto. The other end of the at least one wire W passes through the through hole C of the head portion 611A and through the body portion 611B, where it is electrically connected to the circuit board 13 within the rotatable assembly 12.

[0032] The present invention is not limited by the location of the circuit board 13. In other embodiments, the circuit board 13 is disposed on the first pivot member 61 or the second pivot member 62, or more specifically, on the first housing 611 or the second housing 621. In other words, the optical receiver module 3 and the optical transmitter module 2 are not disposed on the circuit board 13. Therefore, the optical receiver module 3 and the optical transmitter module 2 are electrically connected to the circuit board 13 via other wires, and the control circuit board 5 is further electrically connected to the circuit board 13 via wires W.

[0033] Continue to refer Figure 6 and Figure 7 The shell wall of the body 611B has multiple heat dissipation holes 610, and the first housing 611 has a wire groove 6111 inside, which is adjacent to the multiple heat dissipation holes 610. The multiple heat dissipation holes 610 are interconnected with the internal space of the body 611B and the internal space of the display body 11, allowing heat generated by the components within the display body 11 to dissipate through the multiple heat dissipation holes 610, thereby improving the heat dissipation effect. Furthermore, a fan (not shown) is also provided within the display body 11, and the fan can be located near the heat dissipation holes 610. Therefore, the configuration of the fan can further enhance the heat dissipation effect.

[0034] Furthermore, at least one wire W can be accommodated in the wire groove 6111. The present invention is not limited by the number of wires W. When there are multiple wires W, the design of the wire groove 6111 allows the wires W to be organized and accommodated together, thereby preventing the wires W from becoming entangled or excessively bent, which could result in breakage.

[0035] Advantageous Effects of the Embodiments

[0036] The portable electronic device D provided by the present invention can improve the light transmission / reception efficiency of the light transmission module 2 and the light reception module 3 without increasing the size of the portable electronic device D through the structural design of the light transmission module 2 and the light reception module 3 and protruding from the surface of the device body 1.

[0037] In the prior art, the light emitting module and the light receiving module are installed inside the device body and are not exposed to the outside. Therefore, the light transmission / reception efficiency of the light emitting module and the light receiving module is easily limited by the device body casing. In contrast, the portable electronic device D of the present invention is designed with the light emitting module 2 and the light receiving module 3 protruding from the device body 1. This ensures that the light emitting module 2 and the light receiving module 3 are not blocked by the device body 1 casing when transmitting / receiving light.

[0038] Furthermore, because conventional light emitting and receiving modules are mounted within the device body, such as within the handle, the handle's dimensions (e.g., thickness or volume) inevitably increase, making it difficult for the user to hold the handle securely. In contrast, the light emitting and receiving modules of the present invention protrude from the rotatable component 12 (i.e., the handle) of the device body 1. This allows the rotatable component 12 to be further reduced in size, allowing the user to grip the device more comfortably.
