Description

[0001] The present application belongs to the technical field of communication equipment, and specifically relates to an electronic device. Background Art

[0002] Electronic devices have light sensors. Light emitted by the light sensors can pass through the display screen and out of the electronic device. External light can also pass through the display screen and into the light sensors. The electronic device can perform corresponding functions based on the light detected by the light sensors, such as controlling the screen on and off, as well as the brightness. As users' demand for the display effects of electronic devices increases, electronic devices can have multiple display screens. In related technologies, electronic devices with multiple display screens need to be equipped with multiple light sensors, each for detecting light passing through each display screen. This undoubtedly increases the cost of the electronic device. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the related art that an electronic device with multiple display screens needs to be equipped with multiple light sensors, which increases the cost of the electronic device.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] The present invention discloses an electronic device, comprising a first housing, a second housing, a first display screen, a second display screen, a light sensor, and a light path adjustment member, wherein:

[0006] The first shell and the second shell are rotatably connected to each other so that the electronic device can be switched between an unfolded state and a folded state. The first display screen and the second display screen are located on opposite sides of the first shell. The light sensor is disposed in the first shell, and the light path adjustment member is rotatably disposed in the first shell.

[0007] In the folded state, the optical path adjustment member rotates to the first position, and the light emitted by the optical sensor is reflected by the optical path adjustment member to the first display screen, or the light passing through the first display screen can be reflected by the optical path adjustment member to the optical sensor; in the unfolded state, the optical path adjustment member rotates to the second position, and the light emitted by the optical sensor is reflected by the optical path adjustment member to the second display screen, or the light passing through the second display screen can be reflected by the optical path adjustment member to the optical sensor.

[0008] In an embodiment of the present application, the optical path adjustment member can be switched between a first position and a second position. In the first position, the optical sensor can detect external light on the side of the first display screen, allowing the electronic device to perform a corresponding function. In the second position, the optical sensor can detect external light on the side of the second display screen, allowing the electronic device to perform a corresponding function. In other words, by adjusting the rotation of one optical sensor, it is possible to detect light on both the first display screen and the second display screen, thereby reducing the number of optical sensors used. As can be seen, the embodiment of the present application can solve the problem in the related art that electronic devices with multiple display screens need to be equipped with multiple optical sensors, which increases the cost of the electronic device.

[0032] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0033] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0034] Please refer to Figures 1 to 15 The embodiment of the present application discloses an electronic device, which includes a first housing 110 , a second housing 120 , a first display screen 210 , a second display screen 220 , a light sensor 300 , and an optical path adjustment member 400 .

[0035] The first shell 110 and the second shell 120 are rotatably connected to each other so that the electronic device can switch between an unfolded state and a folded state. The first display screen 210 and the second display screen 220 are located on opposite sides of the first shell. The light sensor 300 is arranged in the first shell 110, and the optical path adjustment member 400 is rotatably arranged in the first shell 110.

[0036] The first display screen 210 can be provided in the first shell 110 and cover at least a portion of the first shell 110. The second display screen 220 can be provided in the first shell 110 and the second shell 120 and cover at least a portion of the first shell 110 and the second shell 120. The second display screen 220 can be a foldable and bendable flexible screen. In the folded state, the second display screen 220 is hidden inside the electronic device, and the first display screen 210 is exposed outside the electronic device. The display area of ​​the first display screen 210 is the display area of ​​the electronic device. In the unfolded state, both the first display screen 210 and the second display screen 220 are exposed outside the electronic device. The display area of ​​the second display screen 220 is the maximum display area of ​​the electronic device. In this case, the use of the second display screen 220 can obtain a larger display area, thereby obtaining a better display effect.

[0037] In the folded state, the optical path adjusting member 400 is rotated to the first position, and the light emitted by the optical sensor 300 is reflected by the optical path adjusting member 400 to the first display screen 210, and is emitted outside the electronic device through the first display screen 210. Alternatively, the light passing through the first display screen 210 can be reflected by the optical path adjusting member 400 to the optical sensor 300. In other words, an optical path is formed between the optical sensor 300 and the first display screen 210 through the optical path adjusting member 400. Please refer to Figure 1 , Figure 1The direction of the middle arrow is the propagation direction of the light when the optical path adjusting member 400 is in the first position.

[0038] In this case, the light sensor 300 can sense the external light on one side of the first display screen 210, so that the electronic device can implement corresponding functions according to the external light on one side of the first display screen 210, such as controlling the screen on, off and brightness of the first display screen 210.

[0039] In the unfolded state, the optical path adjusting member 400 rotates to the second position, and the light emitted by the optical sensor 300 is reflected by the optical path adjusting member 400 to the second display screen 220, and is emitted outside the electronic device through the second display screen 220. Alternatively, the light passing through the second display screen 220 can be reflected by the optical path adjusting member 400 to the optical sensor 300. In other words, an optical path is formed between the optical sensor 300 and the second display screen 220 through the optical path adjusting member 400. Please refer to Figure 2 , Figure 2 The direction of the middle arrow is the propagation direction of the light when the optical path adjustment member 400 is in the second position.

[0040] In this case, the light sensor 300 can sense the external light on one side of the second display screen 220, so that the electronic device can implement corresponding functions according to the external light on one side of the second display screen 220, such as controlling the screen on, off and brightness of the second display screen 220.

[0041] The light sensor 300 may be an infrared light sensor, which can determine the distance between the electronic device and external objects by receiving and emitting infrared light. The electronic device can then control the first display 210 or the second display 220 to turn on or off based on the distance to the external object. For example, when making or receiving a phone call, the infrared light sensor can detect the distance between the electronic device and a person's face. In the folded state, the electronic device controls the first display 210 to turn on or off based on the distance to the face. In the unfolded state, the electronic device controls the second display 220 to turn on or off based on the distance to the face. The specific control process is conventional and will not be described in detail herein.

[0042] The infrared light sensor can also sense ambient light. When the electronic device is folded, the infrared light sensor can sense ambient light on the first display screen 210. The electronic device can control the brightness of the first display screen 210 by varying the intensity of the ambient light on the first display screen 210. When the electronic device is unfolded, the infrared light sensor can sense ambient light on the second display screen 220. The electronic device can control the brightness of the second display screen 220 by varying the intensity of the ambient light on the second display screen 220. The specific control process is conventional technology and will not be described in detail herein.

[0043] Of course, the light sensor 300 may also include an infrared proximity sensor and an ambient light sensor. The infrared proximity sensor transmits and receives infrared light, and the ambient light sensor senses changes in light in the external environment. This document does not limit the specific type of the light sensor 300.

[0044] In the embodiment of the present application, the optical path adjustment member 400 can be switched between a first position and a second position. In the first position, the optical sensor 300 can detect external light on the side of the first display screen 210, enabling the electronic device to perform a corresponding function. In the second position, the optical sensor 300 can detect external light on the side of the second display screen 220, enabling the electronic device to perform a corresponding function. In other words, by adjusting the rotation of one optical sensor 300, it is possible to detect light on both the first display screen 210 and the second display screen 220, thereby reducing the number of optical sensors 300 used. As can be seen, the embodiment of the present application can solve the problem in the related art that electronic devices with multiple display screens need to be equipped with multiple optical sensors, which increases the cost of the electronic device.

[0045] In addition, reducing the number of light sensors 300 used can also reduce the circuit design of the electronic device and reduce redundant circuits within the electronic device.

[0046] There are many ways to achieve switching of the optical path adjustment member 400 between the first position and the second position. In an optional embodiment, the electronic device can be provided with a motor, and the output shaft of the motor can be fixedly connected to the optical path adjustment member 400 so that the motor drives the optical path adjustment member 400 to switch between the first position and the second position.

[0047] In another optional embodiment, the electronic device may further include a hinge mechanism 500, wherein the first shell 110 may be rotatably connected to the second shell 120 via the hinge mechanism 500, and the optical path adjustment member 400 may be connected to the hinge mechanism 500, and the optical path adjustment member 400 may switch between the first position and the second position following the rotation of the first shell 110 relative to the hinge mechanism 500. During the folding or unfolding process of the electronic device, this structure can cleverly establish a transmission relationship between the relative rotation of the first shell 110 and the second shell 120 and the rotation of the optical path adjustment member 400, thereby using the rotation of the first shell 110 and the second shell 120 as the power to drive the rotation of the optical path adjustment member 400, so that the electronic device does not need to be specifically configured with a power source for the optical path adjustment member 400.

[0048] The hinge mechanism 500 may include a first connecting shaft 510, a second connecting shaft 520, and a sleeve 530. The first connecting shaft 510 may be provided on the first shell 110, and the second connecting shaft 520 may be provided on the second shell 120. The sleeve 530 may be provided with a first connecting hole 531 and a second connecting hole 532. The first connecting shaft 510 may be rotatably engaged with the sleeve 530 through the first connecting hole 531, and the second connecting shaft 520 may be rotatably engaged with the sleeve 530 through the second connecting hole 532. Optionally, the first connecting shaft 510 may be rotatably engaged with the first shell 110, and the second connecting shaft 520 may be rotatably engaged with the sleeve 530 through the second connecting hole 532. For example, the end of the first connecting shaft 510 may rotatably extend into the side wall of the first shell 110, and the end of the second connecting shaft 520 may rotatably extend into the side wall of the second shell 120.

[0049] A first sliding groove 540 is provided on the sleeve 530, and the first end 541 of the first sliding groove 540 is at a first distance from the axis of the first connecting shaft 510, and the second end 542 of the first sliding groove 540 is at a second distance from the axis of the first connecting shaft 510, and the first distance is smaller than the second distance.

[0050] The electronic device also includes a connecting rod 600, a first end of the connecting rod 600 is slidingly connected to the first sliding groove 540, and a second end of the connecting rod 600 is rotatably connected to the optical path adjustment member 400. During the relative rotation of the first shell 110 and the second shell 120, the sleeve 530 can rotate relative to the first shell 110, so that the first end of the connecting rod 600 can slide in the first sliding groove 540 as the first shell 110 rotates relative to the second shell 120. During the sliding of the first end of the connecting rod 600 in the first sliding groove 540, the distance between the first end of the connecting rod 600 and the axis of the first connecting shaft 510 changes. Since the relative position of the first connecting shaft 510 and the first shell 110 remains unchanged, the first end of the connecting rod 600 is displaced relative to the first shell 110, so that the connecting rod 600 moves as a whole relative to the first shell 110. The movement of the connecting rod 600 relative to the first shell 110 can drive the optical path adjustment member 400 to rotate.

[0051] This structure is relatively simple and easy to manufacture. In addition, the light sensor 300 can be positioned in the middle of the first housing 110 by means of the connecting rod 600. This prevents the user's hand from blocking the light sensor 300 or casting a shadow near the light sensor 300 when holding the electronic device by its edge, thereby preventing the light sensor 300 from having its detection results deviated, thereby improving the reliability of the light sensor 300 in detecting light.

[0052] Please refer again Figure 9 , Figure 9A structural schematic diagram of the folding state and the unfolded state of the electronic device, wherein the curved line with an arrow represents the movement direction of the second shell 120 during the unfolding process of the electronic device, the arrow on the connecting rod 600 represents the movement direction of the connecting rod 600 during the unfolding process of the electronic device, and d represents the movement distance of the first end of the connecting rod 600 relative to the first shell 110 when the electronic device switches from the folding state to the unfolded state.

[0053] The connecting rod 600 can include a connecting rod body 630 and a first connecting head 610 protruding from the connecting rod body 630. The first connecting head 610 protrudes from the connecting rod body 630 and extends into the first sliding groove 540 to be in sliding fit with the first sliding groove 540. In an alternative embodiment, the connecting rod 600 can further include a second connecting head 620 which can protrude from the connecting rod body 630. An installation hole can be formed on the light path adjusting member 400, and the second connecting head 620 can extend into the installation hole and be in rotatable fit with the installation hole to achieve the rotatable connection of the connecting rod 600 and the light path adjusting member 400.

[0054] In another alternative embodiment, the electronic device can further include a gear assembly 700 which can include a first gear and a second gear. The second end of the connecting rod 600 can be eccentrically connected to the first gear through the second connecting head 620 and be in rotatable connection with the first gear. The second gear is in meshing engagement with the first gear, and the second gear is fixedly connected with the light path adjusting member 400. In this case, the movement distance of the connecting rod 600 and the rotation angle of the light path adjusting member 400 can be controlled through the transmission ratio of the gear assembly 700. In addition, the second gear and the light path adjusting member 400 can be fixedly connected by bonding, which can also avoid the problem of damaging the light path adjusting member 400 by forming an installation hole on the light path adjusting member 400.

[0055] The gear assembly 700 can be a spur gear assembly or a bevel gear assembly. The different transmission directions of the spur gear assembly and the bevel gear assembly can change the placement direction of the light sensor 300, and thus the light sensor 300 and the light path adjusting member 400 and other components related to the light sensor 300 can be flexibly arranged according to the internal space of the electronic device.

[0056] Specifically, the first gear can be a first spur gear 710, the second gear can be a second spur gear 720, and the photosensitive plane of the light sensor 300 can be parallel to the first connecting shaft 510. Please refer again to Figure 11 , Figure 11 A structural schematic diagram of part of the components of the electronic device with the spur gear assembly in the unfolded state, Figure 11The a in the figure represents the rotation angle of the first spur gear 710 when the electronic device switches between the unfolded state and the folded state, and the other arrows represent the movement directions of the components of the electronic device when switching to the unfolded state.

[0057] Alternatively, the first gear may be the first bevel gear 730, the second gear may be the second bevel gear 740, the axis direction of the first bevel gear 730 is perpendicular to the axis direction of the second bevel gear 740, and the photosensitive plane of the optical sensor 300 may be perpendicular to the first connecting axis 510. Please refer again Figure 13 , Figure 13 This is a schematic diagram of the structure of some components of an electronic device with a bevel gear assembly in an unfolded state. Figure 13 The arrows in the figure indicate the movement directions of the components of the electronic device when it is switched to the unfolded state.

[0058] In the above solution, a rotational connection hole can be directly provided on the second gear, and the second connector 620 of the connecting rod 600 can be rotationally connected to the first gear through the rotational connection hole. Alternatively, the first gear can be provided with a second slide groove 750, and the second connector 620 of the connecting rod 600 can extend into the second slide groove 750, so that the second end of the connecting rod 600 slides with the second slide groove 750. During the relative rotation of the first shell 110 and the second shell 120, the second end of the connecting rod 600 drives the first gear to rotate, and the second end of the connecting rod 600 slides within the second slide groove 750. In this case, the sliding of the second end of the connecting rod 600 within the second slide groove 750 can reduce the range of movement of the second end of the connecting rod 600 in a direction perpendicular to the first display screen 210 when the connecting rod 600 moves relative to the first shell 110, thereby reducing the movement space required by the connecting rod 600, which is conducive to the miniaturization design of the electronic device.

[0059] In a further technical solution, the first shell 110 can be provided with a guide rail groove, the extension direction of the guide rail groove is parallel to the first display screen 210, at least a portion of the connecting rod 600 can extend into the guide rail groove, and the connecting rod 600 can slide in cooperation with the guide rail groove. In this case, the guide rail groove can limit the movement direction of the connecting rod 600, so that the movement direction of the connecting rod 600 is parallel to the first display screen 210, further reducing the movement space required by the connecting rod 600, and at the same time, it can also improve the movement accuracy of the connecting rod 600, and avoid interference with other components in the electronic device during the movement of the connecting rod 600. Optionally, the guide rail groove can be directly opened on the inner wall of the first shell 110, or a guide rail can be provided on the inner wall of the first shell 110, and the guide rail groove can be opened on the guide rail.

[0060] In the above scheme, a first slide groove 540 is provided on the sleeve 530, and the first distance between the first end 541 of the first slide groove 540 and the first connecting shaft 510 is smaller than the second distance between the second end 542 and the first connecting shaft 510. The shape of the sleeve 530 can be various. For example, the sleeve 530 can be a cylindrical structure, that is, the cross-section of the sleeve 530 in the direction perpendicular to the axis of the first connecting shaft 510 is circular.

[0061] In the embodiment of the present application, the length of the sleeve 530 in the first direction may be smaller than the length of the sleeve 530 in the second direction. In the unfolded state, the first direction is consistent with the thickness direction of the electronic device, and the second direction is perpendicular to the first direction.

[0062] This structure allows the electronic device to have a smaller dimension of the sleeve 530 in the thickness direction when the electronic device is in the unfolded state, thereby reducing the thickness of the electronic device and facilitating the overall thinness requirements of the electronic device. It should be noted that in the unfolded state, the direction perpendicular to the first display screen 210 and the second display screen 220 is the thickness direction of the electronic device.

[0063] There are many types of optical path adjustment member 400. For example, the optical path adjustment member 400 can be a plane reflector. In the embodiment of the present application, the optical path adjustment member 400 can be a total reflection prism. The total reflection prism can include two right-angled surfaces 410 and an inclined surface 420. The two right-angled surfaces 410 are perpendicularly connected, and the inclined surface 420 is connected to the two right-angled surfaces 410. The angles between the two right-angled surfaces 410 and the inclined surface 420 are both 45 degrees.

[0064] In the first position, the two right-angled surfaces 410 face the first display screen 210 and the light sensor 300, respectively. After the light emitted from the light sensor 300 enters the total reflection prism from one right-angled surface 410, the inclined surface 420 can reflect the light and make it emit from the other right-angled surface 410, and finally projected onto the first display screen 210. Similarly, after the light passing through the first display screen 210 enters the total reflection prism from one right-angled surface 410, the inclined surface 420 can reflect the light and make it emit from the other right-angled surface 410, and finally projected onto the light sensor 300.

[0065] In the second position, the two right-angle surfaces 410 are respectively towards the second display screen 220 and the light sensor 300, and the light emitted by the light sensor 300 enters the total reflection prism from one right-angle surface 410, and then the inclined surface 420 reflects the light to make it emitted from the other right-angle surface 410, and finally projected to the second display screen 220, and by analogy, the light passing through the second display screen 220 enters the total reflection prism from one right-angle surface 410, and then the inclined surface 420 reflects the light to make it emitted from the other right-angle surface 410, and finally projected to the light sensor 300. In this case, the total reflection performance of the total reflection prism can be used to reduce the light loss, and thus enhance the detection accuracy of the light sensor 300 for the light.

[0066] In a further technical solution, in the first position, the two right-angle surfaces 410 can be respectively arranged in parallel with the first display screen 210 and the light sensor 300, and in the second position, the two right-angle surfaces 410 can be respectively arranged in parallel with the second display screen 220 and the light sensor 300. In this case, the light emitted by the light sensor 300 can be emitted vertically to the first display screen 210 or the second display screen 220, or the light vertically incident on the first display screen 210 or the second display screen 220 can be vertically incident on the light sensor 300, so that the light sensor 300 can receive more light, and thus enhance the detection accuracy of the light sensor 300 for the light.

[0067] The electronic device disclosed by the embodiments of the present application can be a smart phone, a tablet computer, an electronic reader or a wearable device. Of course, the electronic device can also be other devices, and the embodiments of the present application do not limit this.

[0068] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the above-described specific embodiments, and the above-described specific embodiments are only illustrative and not restrictive, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims, and all of them belong to the protection of the present application.
