[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The manner described in the following exemplary embodiments does not represent all manner consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0065] Referring to Figures 1-14, this application provides an alarm clock 100.

[0066] As shown in Figures 1-3, the alarm clock 100 includes a display panel 1, a housing 2, and a guide light assembly 3.

[0067] Along the first direction X, the housing 2 includes a front portion 21 and a rear portion 22 disposed opposite to each other. The display panel 1 is fixed to the front portion 21 for real-time intelligent display or for fixing display patterns. Along the second direction Y, the housing 2 includes a top portion 23 and a bottom portion 24 disposed opposite to each other. The bottom portion 24 is used to abut against the table surface 200.

[0068] The guide light assembly 3 is fixed to the housing 2, with at least a portion of its structure exposed outside the housing 2, forming a light-emitting surface 31. The guide light assembly 3 includes a light-emitting element (see Figure 3), and the light emitted by the light-emitting element 33 is diffused outward through the light-emitting surface 31, thereby being captured by the user. The plane containing the light-emitting surface 31 forms an angle with both the first direction X and the second direction Y.

[0069] It should be noted that the first direction X is perpendicular to the second direction Y. In this embodiment, the direction in which the display panel 1 is located is understood as the second direction Y, and the thickness direction of the display panel 1 is the first direction X. The display panel 1 is in a slightly tilted state. Of course, in other embodiments, the first direction X can also be understood as a horizontal direction relative to the front and back, and the second direction Y can be understood as a vertical direction.

[0070] In the above configuration, a guide light group 3 is installed in the alarm clock 100, with its light-emitting surface 31 tilted, meaning that the light-emitting surface 31 forms an angle with both the first direction X and the second direction Y. During normal use, when the alarm clock 100 is placed on the table surface 200, the light emitted from the light-emitting surface 31 directly hits the table surface 200 and then enters the user's eyes through reflection. Of course, if the angle between the user and the alarm clock 100 is unusual, some of the light emitted from the light-emitting surface 31 may also directly enter the user's eyes. This configuration avoids or reduces the direct entry of emitted light into the user's eyes, resulting in a softer visual experience and improved user comfort.

[0071] This configuration makes the guide light group 3 more suitable for use as an ambient light and night light, effectively avoiding excessive brightness and direct light shining into the eyes, thus improving the user experience. When used as an ambient light, it does not affect the observation of the content displayed on the display panel 1. When used as a night light, it avoids the discomfort of direct light shining into the eyes and also avoids affecting the user's sleep experience.

[0072] It should be noted that the guide light group 3 can remain constantly lit; it can also remain constantly lit only during a preset time period / time point; it can also remain lit for a certain duration only when a user command is received; or it can be turned on and off solely based on the user's on / off commands. These can be adjusted according to the application requirements. Alternatively, designers can choose one or more of these options during the design phase.

[0073] Referring again to Figures 1 and 2, the luminous surface 31 faces both the bottom 24 and the front 21 of the alarm clock 100. This arrangement allows the light emitted from the luminous surface 31 to cover a larger area of ​​the tabletop 200, enhancing the user experience.

[0074] In this embodiment, the light-emitting surface 31 is an arc surface. This design ensures the light-emitting effect while improving the overall appearance. Of course, in other embodiments, the light-emitting surface 31 can also be a flat, sloping surface.

[0075] Furthermore, the angle between the plane containing the luminescent surface 31 and the first direction X is greater than or equal to 5° and less than or equal to 70°. By limiting the minimum value of the angle between the luminescent surface 31 and the first direction X, at least some of the light can be diffused forward to cover a larger area of ​​the tabletop 200. By limiting the maximum value of the angle between the luminescent surface 31 and the first direction X, direct light into the user's eyes is avoided, thereby improving the user experience. Additionally,

[0076] It should be noted that when the light-emitting surface 31 is an arc surface, "the plane in which the light-emitting surface 31 is located" should be understood as the tangent at each position on the light-emitting surface 31; when the light-emitting surface 31 is an inclined surface, "the plane in which the light-emitting surface 31 is located" can be directly understood as the plane in which each position on the light-emitting surface 31 is located.

[0077] As shown in Figures 3 and 4, the guide light assembly 3 includes a light guide 32 and the aforementioned light-emitting element 33. The light-emitting element 33 is fixed to the control panel 4 of the alarm clock 100, and both the light-emitting element 33 and the control panel 4 are fixed inside the housing 2.

[0078] At least a portion of the light guide 32 is disposed on the periphery of the light-emitting element 33 away from the control panel 4, for receiving light emitted by the light-emitting element 33; and one end of the light guide 32 is fixed inside the housing 2, the other end is exposed outside the housing 2, and forms a light-emitting surface 31 for transmitting the received light to the light-emitting surface 31.

[0079] The above configuration facilitates the light-emitting element 33 to receive power and commands from the control unit fixed on the control panel 4. Simultaneously, the light guide 32 guides the light emitted by the light-emitting element 33 to ensure a more uniform light distribution before it is transmitted outward through the light-emitting surface 31.

[0080] As shown in Figures 5 and 6, the housing 2 includes an outer shell 25.

[0081] The light guide 32 includes a connected wrapping portion 321 and a limiting portion 322. The limiting portion 322 abuts against the housing 25. A portion of the wrapping portion 321 away from the limiting portion 322 extends to the side of the light-emitting element 33 away from the bottom 24, and the wrapping portion 321, the housing 25, and the control panel 4 form a light-receiving space 5 for accommodating the light-emitting element 33.

[0082] In the above configuration, a portion of the wrapping portion 321 away from the limiting portion 322 extends to the side of the light-emitting element 33 away from the bottom 24, in order to maximize the reception of light emitted by the light-emitting element 33. Simultaneously, the wrapping portion 321, the housing 25, and the control panel 4 form a light-receiving space 5 for accommodating the light-emitting element 33. This space maximizes the reception of light emitted by the light-emitting element 33 and its outward transmission while preventing light leakage to other components, thus avoiding signal interference.

[0083] As shown in Figures 3-9, the limiting part 322 includes an abutting unit 3221, which abuts against the inner wall surface 251 of the outer shell 25 facing the light-emitting element 33.

[0084] The above settings can limit the movement of the light guide 32 and the outer shell 25 to a certain extent.

[0085] The limiting part 322 further includes a first limiting unit 3222, and a second limiting unit 252 is disposed inside the outer shell 25. The first limiting unit 3222 and the second limiting unit 252 are adapted to each other. One of the first limiting unit 3222 and the second limiting unit 252 is a limiting protrusion, and the other is a limiting recess.

[0086] In this application, the first limiting unit 3222 is a limiting protrusion, and the second limiting unit 252 is a limiting recess. Specifically, as shown in the figure, the surface of the outer shell 25 facing the front shell 26 is provided with the aforementioned limiting recess. The light guide 32 includes a limiting protrusion formed on the surface facing the outer shell 25; when the light guide 32 and the outer shell 25 are engaged, the limiting protrusion is located in the limiting recess.

[0087] This design facilitates mold making and the assembly and installation of the light guide 32 and the outer shell 25. Of course, in other embodiments, the opposite can also be achieved.

[0088] Referring to Figures 7 and 9, and if necessary, Figures 3 and 4, in this embodiment, the abutment unit 3221 and the first limiting unit 3222 are spaced apart along the second direction Y and the third direction Z. It should be noted that the third direction Z is perpendicular to the first direction X and the second direction Y. In actual use, the third direction Z can be understood as the left-right direction. This arrangement facilitates installation and ensures the stability of the limiting mechanism.

[0089] Of course, in other embodiments, the abutment unit 3221 and the first limiting unit 3222 may also be spaced apart only along the second direction Y, or spaced apart only along the third direction Z. Such a arrangement can also ensure the stability of the limiting position between the light-emitting element 33 and the outer shell 25.

[0090] The number of abutment units 3221 is multiple, with adjacent abutment units 3221 spaced apart, and the light-emitting element 33 is disposed between two abutment units 3221. In the above arrangement, the abutment unit 3221 can serve as a limiting component and also as a receiver of the light signal from the light-emitting element 33, thereby maximizing the utilization rate of light.

[0091] As shown in Figures 10 and 13, and if necessary, as described in Figures 3 and 4, the housing 2 also includes a front housing 26 and a bracket 27.

[0092] The display panel 1 is fixed to the front shell 26, and the front shell 26 and the outer shell 25 are fixedly connected. The bracket 27 is fixed in the space enclosed by the front shell 26 and the outer shell 25. At least a portion of the guide light assembly 3 is sandwiched between the bracket 27 and the outer shell 25. A notch 261 is provided at the lower part of the front shell 26. When the front shell 26 and the outer shell 25 are fixedly connected, at least a portion of the guide light assembly 3 is exposed through the notch 261 and forms a light-emitting surface 31.

[0093] The above settings enable the assembly of the guide light group 3 and the housing 2.

[0094] Referring to Figures 6-10, the light guide 32 includes an extension 323 that enters the notch 261. The extension 323 includes a first mating surface 3231 and a second mating surface 3232. The first mating surface 3231 mates with the surface of the outer shell 25 facing the notch 261; the second mating surface 3232 mates with the surface of the front shell 26 facing the notch 261. This arrangement improves the fit between the extension 323 and the front shell 26 and the outer shell 25, preventing external impurities from entering the interior of the shell 2 through the gap between the extension 323 and the front shell 26 and the outer shell 25.

[0095] Meanwhile, the plane on which the second mating surface 3232 is located forms an angle with both the first direction X and the second direction Y. Furthermore, because the gap between the extension 323 and the front shell 26 is set ahead of the center, external impurities and dust can more easily enter the interior of the outer shell 25 through this gap. Therefore, the second mating surface 3232 is set as an inclined plane to minimize or prevent external impurities from entering the interior of the shell 2 through the gap between the extension 323 and the front shell 26.

[0096] At least a portion of the limiting protrusion is provided on the surface of the extension 323. In the above arrangement, the limiting protrusion can further restrict the position of the extension 323 located in the notch 261, thus serving a positioning function.

[0097] Referring to Figures 6-10, the wrapping portion 321 includes an inclined unit 3211, and the plane where the inclined unit 3211 is located makes an angle with the first direction X. In the above configuration, by setting the inclined unit 3211, the area of ​​the wrapping portion 321 that receives light emitted by the light-emitting element 33 is increased, and at the same time, it is beneficial for light to directly enter the interior of the inclined unit 3211.

[0098] Along the thickness direction of the tilting unit 3211, the surface of the tilting unit 3211 facing the light-emitting element 33 is designated as the first surface 3212, and the surface of the tilting unit 3211 away from the light-emitting element 33 is designated as the second surface 3213. The roughness of the first surface 3212 is a first roughness, and the roughness of the second surface 3213 is a second roughness. The first roughness is greater than the second roughness.

[0099] In the above configuration, the first surface 3212 is relatively rough. Light emitted from the light-emitting element 33, upon reaching the rougher first surface 3212, is prone to slow reflection and more easily enters the interior of the tilting unit 3211, minimizing the number of reflections the light needs to undergo in the light-receiving space 5 before entering the light guide 32. Simultaneously, the second surface 3213 is relatively smooth. Light entering the tilting unit 3211, upon reaching the second surface, can be reflected back to the light guide 32 as directly as possible, minimizing outward refraction through the second surface 3213. This configuration maximizes light utilization.

[0100] Referring to Figures 6-10, the wrapping portion 321 further includes an extension unit 3214, which extends from one end of the tilting unit 3211 towards the control panel 4. The extension unit 3214 is located at the end of the light-emitting element 33 away from the bottom 24. The plane of the extension unit 3214 is parallel to the first direction X. Since there is an angle between the tilting unit 3211 and the first direction X, the tilt degree of the extension unit 3214 along the first direction X is less than that of the tilting unit 3211. Of course, in other embodiments, the plane of the extension unit 3214 may not be parallel to the first direction X, as long as the angle formed by the extension unit 3214 and the first direction X is less than the angle formed by the tilting unit 3211 and the first direction X.

[0101] With the above settings, while ensuring that the light emitted by the light-emitting element 33 can be received to the maximum extent, the volume occupied by the light guide element 32 inside the outer shell 25 is reduced to the greatest extent, which is conducive to realizing the miniaturization design of the alarm clock 100.

[0102] Specifically, the angle α between the plane where the tilting unit 3211 is located and the first direction X is greater than or equal to 5° and less than or equal to 70°. Extensive experiments have shown that by setting the angle α within this range, the area of ​​the wrapping portion 321 that receives light emitted by the light-emitting element 33 can be increased most effectively, facilitating direct light entry into the tilting unit 3211. Simultaneously, the area occupied by the wrapping portion 321 within the outer casing 25 can be effectively controlled, contributing to the miniaturization of the alarm clock 100. In this embodiment, the angle α is preferably controlled within the range of 30°-60°.

[0103] As shown in Figure 6, along the first direction X, there is a first gap d1 between the extension unit 3214 and the control panel 4. The minimum value of the first gap d1 is greater than or equal to 0.1 mm and less than or equal to 5 mm.

[0104] In the above configuration, by limiting the minimum value of the first gap d1, a sufficient gap is maintained between the extension unit 3214 and the control panel 4 to prevent relative displacement between the extension unit 3214 and the control panel 4 during impacts to the alarm clock 100, thus preventing damage to the control panel 4 by the extension unit 3214. By limiting the maximum value of the first gap d1, the extension unit 3214 can receive as much light as possible from the light-emitting element 33. Simultaneously, light leakage from the light-emitting element 33 is minimized to prevent it from affecting the normal operation of other components.

[0105] As shown in Figure 6, along the second direction Y, there is a second gap d2 between the extension unit 3214 and the light-emitting element 33. The minimum value of the second gap d2 is greater than or equal to 0.2 mm and less than or equal to 2 cm.

[0106] In the above configuration, by limiting the minimum value of the second gap d2, a sufficient gap is maintained between the extension unit 3214 and the light-emitting element 33 to prevent relative displacement between the extension unit 3214 and the light-emitting element 33 during impacts to the alarm clock 100, thus preventing damage to the control panel 4 by the light-emitting element 33. By limiting the maximum value of the second gap d2, the extension unit 3214 can receive as much light as possible from the light-emitting element 33.

[0107] As shown in Figures 5-10, fixing units 3215 are formed on the two sides of the extension unit 3214 that are opposite to each other along the third direction Z. The fixing units 3215 are used to fix and connect to the control panel 4.

[0108] The above-described configuration achieves a fixed connection for the light guide 32. In this embodiment, the alarm clock 100 further includes a first fastener 6, which passes through the fixing unit 3215 and the control panel 4 to achieve a fixed connection between the two.

[0109] Referring to Figures 6-10, the wrapping portion 321 further includes a connecting unit 3216, the two ends of which are connected to the limiting portion and the tilting unit 3211, respectively. This arrangement avoids the tilting unit 3211 and the horizontal limiting unit from forming an excessively sharp angle, thus achieving a relatively smooth connection between the two.

[0110] Referring to Figures 10-14, in this application, a protective space 271 is also provided at the end of the bracket 27 furthest from the front housing 26. The alarm clock 100 also includes a light signal receiving device fixed to the control panel 4. The light signal receiving device is used to receive external light signals, and the control unit electrically connected to the control panel 4 can determine the display brightness of the display panel 1 based on the external light signals. The light signal receiving device is located within the protective space 271 to minimize interference from the light emitted by the light-emitting element 33.

[0111] Additionally, as shown in Figures 3 and 14, in this embodiment, the outer casing 25 further includes a main body 253, an upper cover 254, and a rear cover 255. The main body 253 is fixedly connected to the front casing 26. The upper cover 254 is fixed above the main body 253. The rear cover 255 is fixed to the rear of the main body 253 to protect the sound-generating device 9 located in the main body 253.
