Description

Technical Field

[0001] This application belongs to the field of electronic device design technology, and specifically relates to an electronic device. Background Technology

[0002] The intelligence of electronic devices brings users numerous conveniences. Communication between electronic devices and other products, as well as control of other products, is often achieved through infrared remote control. While users have high demands for the functionality of electronic devices, they also have high requirements for their appearance. Due to aesthetic requirements, the light-emitting aperture is usually located in the center of the electronic device's casing. However, because other functional components need to be arranged inside the electronic device, there is a significant deviation between the optical axis of the light-emitting element and the central axis of the light-emitting aperture. This significant deviation reduces the amount of light emitted from the aperture and decreases the emission angle of the light emitted from the aperture, resulting in a deterioration in the infrared remote control performance of the electronic device. Summary of the Invention

[0003] The purpose of this application is to disclose an electronic device that can solve the problem of deteriorated infrared remote control performance of electronic devices in the background art due to a large deviation between the optical axis of the light-emitting element and the central axis of the light-emitting hole.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, this application discloses an electronic device, which includes a housing, a light-emitting element, a first light-distributing element, and a second light-distributing element, wherein...

[0006] The housing has an inner cavity and a light-emitting hole communicating with it. The light-emitting element and the first light-distributing element are disposed in the inner cavity. The second light-distributing element is located inside the housing, and at least a portion of the second light-distributing element is installed in the light-emitting hole.

[0007] The light-emitting element is misaligned with the light-emitting aperture;

[0008] The first light distribution element is used to receive and adjust the light emitted by the light-emitting element, and to project the light onto the second light-incident surface of the second light distribution element after it is transmitted toward the side where the light-emitting hole is located.

[0009] The second light distribution element is used to receive the light, focus the received light to a focal point, and project it from the focal point through the light outlet hole to the outside of the housing.

[0010] The technical solution adopted in this application can achieve the following beneficial effects:

[0011] The electronic device disclosed in this application improves the structure of electronic devices in related technologies by setting a first light distribution element and a second light distribution element between the staggered light-emitting element and the light-emitting hole. Since the first light distribution element can receive and adjust the light emitted by the light-emitting element, and make the light deflect towards the side where the light-emitting hole is located before being projected onto the second light distribution element, the first light distribution element can initially correct the light emitted by the light-emitting element. The light projected onto the second light distribution element can converge to a focal point in the second light distribution element, which is equivalent to making the light project from a focal point closer to the light-emitting hole. This allows the light to cross the light path in the second light distribution element, so that the light emitted from the second light distribution element and then projected onto the outside of the housing through the light-emitting hole has a larger emission angle and emission amount, thereby improving the infrared remote control performance of the electronic device.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The electronic devices disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] like Figures 1 to 8 As shown in the figure, this application discloses an electronic device, which includes a housing 100, a light-emitting element 200, a first light-distributing element 300, and a second light-distributing element 400.

[0029] The housing 100 is the basic component of the electronic device, providing protection for its internal components. The housing 100 has an inner cavity 110 and a light-emitting aperture 120 communicating with it, connecting the inner cavity 110 to the external environment. The light-emitting element 200 emits light; specifically, it can be an infrared LED. Both the first light-distributing element 300 and the second light-distributing element 400 correct the light transmission path. The light-emitting element 200 and the first light-distributing element 300 are located in the inner cavity 110, while the second light-distributing element 400 is located within the housing 100, with at least a portion of the second light-distributing element 400 installed within the light-emitting aperture 120.

[0030] The light-emitting element 200 and the light-emitting aperture 120 are misaligned. That is, the optical axis of the light-emitting element 200 and the central axis of the light-emitting aperture 120 are separated by a certain distance in a direction perpendicular to the optical axis, resulting in an off-center arrangement between the light-emitting element 200 and the light-emitting aperture 120. Furthermore, there is a greater than zero distance between the light-emitting element 200 and the light-emitting aperture 120 along the optical axis. Under these circumstances, a significant portion of the light emitted by the light-emitting element 200 is difficult to directly exit through the light-emitting aperture 120, even if the amount of light emitted through the light-emitting aperture 120 is relatively small, and the exit angle of the light emitted through the light-emitting aperture 120 is also small.

[0031] To ensure that most of the light emitted by the light-emitting element 200 can exit from the light-emitting hole 120 at a large light-emitting angle to the outside of the housing 100 for infrared remote control of devices such as televisions, in this application, the first light distribution element 300 can receive and adjust the light emitted by the light-emitting element 200, and cause the light to be transmitted towards the side where the light-emitting hole 120 is located before being projected onto the second light-incident surface 420 of the second light distribution element 400. Then, the second light distribution element 400 can receive the light and concentrate the received light to a focal point, so that the light in the light-emitting element 200, after being distributed by the first light distribution element 300 and the second light distribution element 400, converges to a focal point in the second light distribution element 400. This allows the light to cross paths in the second light distribution element 400, which is equivalent to moving the position of the light-emitting element 200 into the second light distribution element 400. The light that crosses paths can increase the light-emitting angle and concentrate the light, which is beneficial to reducing the aperture size of the light-emitting hole 120.

[0032] It should be added that, under the action of the second light distribution element 400, the light can converge to a focal point, thus achieving light path intersection. This focal point is a virtual focal point. In the field of optics, the light can be converged to this focal point by designing the surface shape of the second light-incident surface 420 of the second light distribution element 400. The light converged to this focal point will then be emitted from the light-exiting aperture 120. In this process, the converged focal point is realized in the second light distribution element 400, so this focal point is closer to the light-exiting aperture 120. In this case, the formation of this focal point is equivalent to moving the light-emitting element 200 a certain distance closer to the light-exiting aperture 120, so that the light-emitting element 400 can project light into the light-exiting aperture 120 from a position closer to the light-exiting aperture 120. This can alleviate the obstruction of the light projection of the light-emitting element 400 by the light-exiting aperture 120, thereby helping to increase the actual exit angle of the light projected from the light-exiting aperture 120.

[0033] Compared to the distance between the light-emitting element 200 and the light-emitting aperture 120, the distance between the second light-distributing element 400 and the light-emitting aperture 120 is closer. This allows the light rays converging at the focal point to have a larger light output and a larger light output angle when projected outside the housing 100 through the light-emitting aperture 120. In other words, the first light-distributing element 300 and the second light-distributing element 400 provided in this application can solve the problem of degraded infrared remote control performance of electronic devices when the light-emitting element 200 and the light-emitting aperture 120 have a large off-center distance.

[0034] The first light distribution element 300 can correct the light to a certain extent, while the second light distribution element 400 can concentrate the light projected from the first light distribution element 300 to a focal point closer to the light exit aperture 120, thereby alleviating the limitation of the light exit aperture 120 on the light exit angle. Of course, it can also make more of the light emitted by the light-emitting element 200 be corrected before being projected from the light exit aperture 120.

[0035] The electronic device disclosed in this application improves the structure of electronic devices in related technologies by setting a first light distribution element 300 and a second light distribution element 400 between the staggered light-emitting element 200 and the light-emitting hole 120. Since the first light distribution element 300 can receive and adjust the light emitted by the light-emitting element 200, and make the light deflect towards the side where the light-emitting hole 120 is located before being projected onto the second light distribution element 400, the first light distribution element 300 can perform preliminary correction on the light emitted by the light-emitting element 200. The light projected onto the second light distribution element 400 can converge to a focal point in the second light distribution element 400, so that the light can achieve optical path crossing in the second light distribution element 400. This results in a larger light emission angle and light emission amount of the light that passes through the second light distribution element 400 and is projected onto the outside of the housing 100 through the light-emitting hole 120, thereby improving the infrared remote control performance of the electronic device.

[0036] Specifically, the first light distribution element 300 can be a bent light guide column. The light guide column adjusts the direction of light through its own bending structure, thereby achieving a correction effect, that is, compensating for the deviation between the light-emitting element 200 and the light-emitting aperture 120. Of course, to simplify the structure, the first light distribution element 300 can have a first light-emitting surface 310, which is a first convex surface protruding towards the second light distribution element 400. The formation of the first convex surface makes the first light distribution element 300 resemble a convex lens, thereby adjusting the light path through light refraction. Furthermore, the first convex surface can assist in light convergence to a certain extent, so that the light projected onto the second light distribution element 400 is pre-convex to a certain degree. Then, under the action of the second light distribution element 400, it is more conducive to the light being projected onto the second light distribution element 400 and converging at a focal point.

[0037] The second light-distributing element 400 has a second light-incident surface 420, which can be a second convex surface protruding towards the first light-distributing element 300. In this case, the second light-distributing element 400 with the second convex surface is also similar to a convex lens, which is more conducive to the convergence of light rays to a focal point after they are projected into it. Of course, there are various optical structures that can achieve the convergence of light rays to a focal point, and this application does not limit the specific structure of the second light-distributing element 400.

[0038] In the electronic device disclosed in the embodiments of this application, the first light distribution element 300 may have a first light emitting surface 310. The first light emitting surface 310 may include a first sub-light emitting surface 311 and a second sub-light emitting surface 312. The second sub-light emitting surface 312 is disposed around the first sub-light emitting surface 311, and the curvature of the second sub-light emitting surface 312 is greater than the curvature of the first sub-light emitting surface 311.

[0039] In this case, the second sub-emitting surface 312, with its larger curvature, has a stronger deflection capability for light, meaning it deflects light at a larger angle. Conversely, the first sub-emitting surface 311, with its smaller curvature, has a weaker deflection capability, meaning it deflects light at a smaller angle. This results in the first and second sub-emitting surfaces 311 and 312 having different deflection capabilities for light emitted from the first emitting surface 310. Since the second sub-emitting surface 312 is positioned around the first sub-emitting surface 311, their deflection directions can differ. This allows the second sub-emitting surface 312 to deflect light closer to the first sub-emitting surface 311, thereby converging the light passing through the first light distributor 300 and preventing excessive expansion of the light emitted from the light-emitting element 200 by the first light distributor 300.

[0040] Optionally, the width of the effective light emitted by the light-emitting element 200 can be a first width, and the width of the effective light emitted by the first light-emitting surface 310 can be a second width. The ratio of the second width to the first width can be less than 1.35, thereby avoiding a large expansion of the light emitted by the light-emitting element 200 by the first light distribution element 300, which would reduce the utilization rate of the light. It should be noted that, in this article, width refers to the maximum dimension of the corresponding object in the plane perpendicular to the optical axis X1.

[0041] In the electronic device disclosed in the embodiments of this application, there may be a gap between the first light distribution element 300 and the second light distribution element 400, so as to avoid direct contact between the first light distribution element 300 and the second light distribution element 400. This can prevent the first light distribution element 300 and the second light distribution element 400 from colliding with each other when the electronic device is shaken or bumped, thereby causing the first light distribution element 300 and the second light distribution element 400 to move and affect the light distribution effect on the light-emitting element 200, or even causing the first light distribution element 300 and the second light distribution element 400 to be damaged due to collision, thereby affecting the infrared remote control performance of the electronic device.

[0042] In the electronic device disclosed in this application, the first light-distributing element 300 may have a first light-incident surface 320, for example, the first light-incident surface 320 may be a sawtooth surface. In this case, the sawtooth surface is beneficial for adjusting the path of light, thereby facilitating the guidance of light passing through the first light-distributing element 300 towards the light-exiting aperture 120. The size of the sawtooth angle of the sawtooth surface can be specifically set according to the need to adjust the deflection angle of the light, and this application does not impose specific limitations on the size of the sawtooth angle of the sawtooth surface.

[0043] In one optional technical solution, the sawtooth surface may include a sawtooth bevel 321, and the angle between the sawtooth bevel 321 and the optical axis X1 of the light-emitting element 200 may be 60±2°, that is, 58°~62°. In this case, specifically, the angle between the sawtooth bevel 321 and the optical axis X1 of the light-emitting element 200 may be 60°, so as to deflect the light emitted from the light-emitting element 200 at a certain angle. It should be noted that the angle between the sawtooth bevel 321 and the optical axis X1 of the light-emitting element 200 may also be 58° or 61°, etc. This application does not specifically limit the angle between the sawtooth bevel 321 and the optical axis X1 of the light-emitting element 200, and the optical axis X1 of the light-emitting element 200 is parallel to the central axis X2 of the light-emitting aperture 120. Of course, the sawtooth surface may also include a sawtooth straight surface 322. Near the edge of the light outlet 120, the sawtooth straight surface 322 intersects with the sawtooth inclined surface 321. The sawtooth straight surface 322 is parallel to the optical axis X1, so that the included angle between the sawtooth inclined surface 321 and the sawtooth straight surface 322 can be 60±2°.

[0044] In order to enable the second light-incident surface 420 to receive the light emitted from the first light-emitting surface 310 more conveniently, in a further technical solution, the electronic device may also include a display screen 500. The second light-incident surface 420 may be a hemisphere. The tangent plane at the center of the second light-incident surface 420 is parallel to the sawtooth inclined surface 321. The angle between the sawtooth inclined surface 321 and the central axis X2 of the light-emitting aperture 120 is an acute angle. The distance between the edge of the second light-incident surface 420 away from the display screen 500 and the light-emitting aperture 120 is smaller than the distance between the edge of the second light-incident surface 420 adjacent to the other side of the display screen 500 and the light-emitting aperture 120. In this case, the light incident on the sawtooth inclined surface 321 is deflected in the direction of the central axis X2. Since the distance between the edge of the second light-incident surface 420 away from the display screen 500 and the light-emitting hole 120 is smaller than the distance between the edge of the second light-incident surface 420 adjacent to the other side of the display screen 500 and the light-emitting hole 120, the part of the second light-incident surface 420 that is closer to the display screen 500 has a larger receiving area for the light emitted from the first light-emitting surface 310, which is beneficial for receiving the deflected light emitted from the sawtooth inclined surface 321.

[0045] Considering that users habitually tilt the end of the electronic device with the light-emitting hole 120 upwards at an angle when using the infrared remote control function of the electronic device, and the product to be remotely controlled (such as a television) is usually below the light-emitting hole 120, the light from the light-emitting hole 120 needs to be emitted towards the remotely controlled product located below. To ensure that the light emitted from the light-emitting hole 120 can be emitted downwards, in the electronic device disclosed in this application embodiment, the second light distribution element 400 may have a second light-emitting surface 410. The second light-emitting surface 410 is a first plane, and the plane where the light-emitting port of the light-emitting hole 120 is located is a second plane. A first angle is formed between the first plane and the second plane, with the angle ranging from 1° to 3°. In this case, the second plane is the plane where the outer surface of the housing 100 is located, and the angle between the first plane and the second plane indicates that the first plane is inclined relative to the second plane. The inclined first plane is beneficial for deflecting the light, thereby making it easier for the light emitted from the light-emitting hole 120 to be emitted onto the remotely controlled product.

[0046] Specifically, the angle between the first and second planes can be 2°. Of course, the angle between the first and second planes can also be 1° or 3°, etc. This application does not limit the specific angle between the first and second planes. Furthermore, since the first plane is only tilted at a small angle, the user can hardly observe the tilt relative to the second plane, which is beneficial to the user experience. Compared to setting the first plane to be textured to deflect light, a smoother first plane is more conducive to meeting the requirements of a refined appearance for electronic devices.

[0047] In a further technical solution, the second light-emitting surface 410 can be recessed into the light-emitting aperture 120. In this case, the first plane formed by the second light-emitting surface 410 is a retracted structure relative to the light-emitting aperture 120, which can prevent the tilted first plane from protruding out of the light-emitting aperture 120, thereby helping to protect the first plane.

[0048] In the electronic device disclosed in this application embodiment, the second light-incident surface 420 may include a total internal reflection structure surface, which is used to receive light and converge the received light to a focal point. In this case, the total internal reflection structure surface can achieve complete reflection of the light projected onto the second light-incident surface 420, which is beneficial to improving the utilization rate of the light emitted from the light-emitting element 200.

[0049] In the electronic device disclosed in this application embodiment, the housing 100 may include a frame 130, an internal support frame 140, and a circuit board 150. The internal support frame 140 is disposed within the frame 130, the circuit board 150 is fixed to the internal support frame 140, the light-emitting element 200 is mounted on the circuit board 150, the first light-distributing element 300 is mounted on the internal support frame 140, the second light-distributing element 400 is mounted on the frame 130, and the light-emitting hole 120 is opened in the frame 130. In this case, the frame 130 can serve as the mounting base for the electronic device, allowing the internal support frame 140 to be disposed on the frame 130. Simultaneously, the internal support frame 140 can also serve as the mounting base for other components, allowing the first light-distributing element 300 to be mounted on the internal support frame 140. The circuit board 150 enables internal circuit connections and control of the electronic device and provides power to the light-emitting element 200.

[0050] The electronic device may also include components such as a battery cover 170 and a display screen 500. The battery cover 170 is mounted on the frame 130, and the display screen 500 is mounted on the internal support frame 140. The plane on which the display screen 500 is located is perpendicular to the thickness direction of the electronic device for installation.

[0051] During the assembly of electronic devices, an assembly gap 160 is generated between the second light distribution component 400 and the frame 130. In order to improve the connection stability between the second light distribution component 400 and the frame 130, adhesive can be filled into the assembly gap 160. The adhesive can be, for example, photosensitive adhesive. This reduces the gap and improves the connection stability between the second light distribution component 400 and the frame 130.

[0052] The electronic devices disclosed in this application can be mobile phones, PDAs, game consoles, and e-readers, etc. This application does not limit the specific types of electronic devices.

[0053] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0054] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
