DETAILED DESCRIPTION

[0042] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0043] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0044] refer to Figures 1 to 3 , the present application provides an alarm clock 100. The alarm clock 100 includes a main shell portion 1, an upper shell portion 2 and a front shell portion 3. The main shell portion 1 includes a front surface 11 and a top surface 12 adjacent to each other, and encloses a first accommodating cavity 61 forming the alarm clock 100. The front shell portion 3 is arranged on the front surface 11 and includes a display opening 31. The display opening 31 is connected to the first accommodating cavity 61. The upper shell portion 2 is arranged on the top surface 12 and includes a protruding unit 21 protruding away from the top surface 12. The upper shell portion 2 and the top surface 12 enclose a second accommodating cavity 62 forming the alarm clock 100. The upper shell portion 2 includes a button opening 22 arranged on the side of the protruding unit 21 away from the top surface 12. The button opening 22 is connected to the second accommodating cavity 62.

[0045] As can be seen, the cooperation between the main housing portion 1 and the front housing portion 3 of the alarm clock 100 of the present application enables the first accommodating chamber 61 to communicate with the outside world through the display opening 31. The cooperation between the main housing portion 1 and the upper housing portion 2 forms a second accommodating chamber 62 independent of the first accommodating chamber 61. The second accommodating chamber 62 communicates with the outside world through the key opening 22. It should be understood that the independence of the first accommodating chamber 61 and the second accommodating chamber 62 can be understood as complete isolation or as communication at some point.

[0046] Based on this, the alarm clock 100 of the present application further includes a button portion 4 and a display portion 5. The display portion 5 is disposed in the first accommodating cavity 61 and abuts against the side of the front shell portion 3 facing the first accommodating cavity 61. The display portion 5 is exposed through the display opening 31. The button portion 4 is disposed in the second accommodating cavity 62 and includes a button unit 41 exposed through the button opening 22. The display portion 5 should be understood as a display screen that displays time information. The button portion 4 is used to control the operation of the alarm clock 100.

[0047] When the user holds the alarm clock 100 with the palm of his hand and turns the side of the display opening 31 toward himself, the user's thumb naturally extends toward the direction of the upper shell 2. Therefore, the combination of the protruding unit 21 and the button part 4 of the present application can make the alarm clock 100 have a more ergonomic appearance, which is convenient for the user to operate the button part 4. And the button part 4 is arranged in the second accommodating cavity 62, so the electrical control structure of the button part 4 can be isolated from the electrical control structure of the display part 5 located in the first accommodating cavity 61, that is, the electrical control structures of the two can at least maintain a relatively independent state. In this way, the wiring design of the button part 4 can be separated from the wiring design of the display part 5. This not only reduces the difficulty of wiring inside the alarm clock 100, but also optimizes the internal space of the alarm clock 100.

[0048] Furthermore, the display portion 5 abuts the front housing portion 3 within the first accommodating cavity 61, thus providing some protection for the display portion 5. When the alarm clock 100 is struck by an external force, the front housing portion 3 can, to a certain extent, prevent the external force from being directly applied to the display portion 5. This indicates that the front housing portion 3 effectively extends the service life of the display portion 5.

[0049] Because the upper shell 2 is provided with the protruding unit 21, compared to a solution in which the upper shell 2 and the main shell 1 are integrated, the design of the present application with the main shell 1 and the upper shell 2 being separated facilitates the demolding operation of the upper shell 2 and the main shell 1 during the manufacturing process. This not only reduces the difficulty and cost of mold design, but also improves the yield rate during the production of the alarm clock 100.

[0050] The display unit 5 can be used only to display information. In some embodiments, the display unit 5 is a touch display unit 5. In this embodiment, the user can operate the display unit 5 by touching the display side to adjust the time, function, etc. This setting method is conducive to improving the adjustment convenience of the alarm clock 100 and can provide the user with a more intelligent user experience. The display unit 5 can be an OLED screen, an LCD screen, a capacitive touch screen, etc. This application is not limited to this.

[0051] In some optional embodiments, the alarm clock 100 further includes a first inner housing portion 71. The first inner housing portion 71 is disposed within the first accommodating cavity 61 and is connected to the side of the display portion 5 facing away from the front housing portion 3. The first inner housing portion 71 provides support for the display portion 5 on one side of the first accommodating cavity 61. When assembling the alarm clock 100, the display portion 5 is first connected to the first inner housing portion 71, and then the assembler connects the front housing portion 3 to the main housing portion 1.

[0052] Furthermore, a limiting unit 33 is extended from the front shell portion 3 toward one side of the first accommodating cavity 61. The limiting unit 33 is connected to the peripheral side of the first inner shell portion 71. The provision of the first inner shell portion 71 can provide support for the display portion 5. When the display portion 5 is subjected to a force directed from the display surface 32 to the accommodating cavity, the first inner shell portion 71 can prevent the display portion 5 from bending toward the inside of the first accommodating cavity 61. The cooperation between the limiting unit 33 and the first inner shell portion 71 can limit the movement of the display portion 5 parallel to the display surface 32. When the alarm clock 100 is hit or shaken, the limiting unit 33 and the first inner shell portion 71 can prevent the display portion 5 from shifting and shaking, which is beneficial to extending the service life of the alarm clock 100.

[0053] Figure 1 In the illustrated embodiment, a plurality of limiting units 33 are provided, and the plurality of limiting units 33 are spaced apart and respectively connected to the circumference of the first inner shell 71. This arrangement can reduce the precision requirements for the fit between the limiting units 33 and the first inner shell 71, thereby reducing the production cost of the alarm clock 100. This application does not impose any specific restrictions on the number, location, or size of the limiting units 33. In other embodiments, there can also be only one limiting unit 33, which is arranged around the circumference of the first inner shell 71, thereby improving the abutment strength of the limiting unit 33.

[0054] The connection between the limiting unit 33 and the first inner shell 71 can be achieved through bonding, magnetic attraction, or other methods. In an optional embodiment, the first inner shell 71 and the limiting unit 33 are connected via a snap-fit connection. This snap-fit connection can improve the assembly efficiency of the panel and the first inner shell 71, while also facilitating disassembly and repair of components within the accommodating cavity. For example, the first inner shell 71 is provided with a hole, and the limiting unit 33 is provided with a raised snap-fit. The hole and the snap-fit fit together to achieve a snap-fit connection.

[0055] In some optional embodiments, a light opening 34 is provided on the side of the front housing 3 away from the top surface 12. The alarm clock 100 further includes a light module 8. The light module 8 is connected to the first inner housing 71 and is exposed from the light opening 34 so that the light emitted by the light module 8 can leave the alarm clock 100. In fact, in this embodiment, the light opening 34 is provided toward the bottom surface 13 of the main housing 1 and is not connected to the display opening 31. Therefore, when the alarm clock 100 is turned on, the light module 8 is turned off. Figure 2 When the alarm clock 100 is viewed from the perspective shown, the front housing 3 is provided between the display portion 5 and the light module 8. The light module 8 is exposed from the light opening 34 on one side of the bottom surface 13, so that Figure 5 As shown, light from the lighting module 8 (indicated by the blue arrow) first reaches the placement surface 200, then is reflected and scattered by the placement surface 200 before entering the user's eyes. In this way, the alarm clock 100 can soften the light from the lighting module 8, preventing direct light from entering the eyes and causing damage to the eyes. Furthermore, the soft light of the lighting module 8 can be used as a night light at night, reducing the impact on the user's sleep.

[0056] As can be seen, the provision of the first inner shell portion 71 can provide connection and support for multiple components within the first accommodating chamber 61. Compared to a solution that provides a separate connection bracket for each component, the first inner shell portion 71 can reduce the number of components within the first accommodating chamber 61 while optimizing space utilization within the first accommodating chamber 61.

[0057] refer to Figure 4 In some optional embodiments, the display opening 31 includes a first sub-opening 311 and a second sub-opening 312. The second sub-opening 312 is disposed between the first accommodating cavity 61 and the first sub-opening 311. That is, light from the display portion 5 leaves the first sub-opening 311 via the second sub-opening 312. Figure 4 As shown, the size of the first sub-opening 311 gradually decreases in the direction from the first sub-opening 311 to the second sub-opening 312. The maximum size of the second sub-opening 312 is less than or equal to the minimum size of the first sub-opening 311. The slope of the first sub-opening 311 makes the transition between the display surface 32 and the display opening 31 smoother. When the user is a child, this setting can prevent the child's skin from being scratched by sharp edges. In addition, the slope of the first sub-opening 311 can strengthen the structural strength of the transition between the display surface 32 and the display opening 31, preventing damage to the front shell 3 due to bumps.

[0058] The maximum size of the second sub-opening 312 is smaller than or equal to the minimum size of the first sub-opening 311 and can be as follows: Figure 4 As shown, the second sub-opening 312 has a uniform size and extends straight to the display portion 5 .

[0059] Alternatively, the size of the second sub-opening 312 gradually decreases in the direction from the first sub-opening 311 to the second sub-opening 312. Moreover, the size change range of the second sub-opening 312 is smaller than the size change range of the first sub-opening 311. Figure 4 Taking the perspective as an example, the size change amplitude of the second sub-opening 312 is smaller than the size change amplitude of the first sub-opening 311. It should be understood that the slope of the projection line of the first sub-opening 311 is greater than the slope of the projection line of the second sub-opening 312. That is, the circumferential inclination of the first sub-opening 311 is greater than the circumferential inclination of the second sub-opening 312. In this way, the transition of the display opening 31 from the display surface 32 to the display portion 5 is smoother, and the user has a better tactile feeling when touching the display opening 31. In the embodiment where the display portion 5 is a touch display portion, the tilted setting of the first sub-opening 311 and the second sub-opening 312 makes the tactile feeling better when the user's finger is placed on the display opening 31 for touching, and it is more convenient for the user to click the display portion 5 close to the display opening 31, reducing the dead angle of touch.

[0060] Combine Figure 4 , optionally, the depth D1 of the display opening 31 is greater than or equal to 1.8 mm and less than or equal to 2.5 mm. For example, the depth D1 can be 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm or any value therebetween. If the depth D1 is too large, the front shell 3 may be too thick, or the display part 5 may be recessed too deeply, making it inconvenient to view the display part 5 in a standing position or the like. If the depth D1 is too small, the protective function of the front shell 3 for the display part 5 may be weakened. Therefore, the depth D1 range can better balance the protective performance of the front shell 3 and prevent the front shell 3 from excessively blocking the display part 5.

[0061] Optionally, the main housing 1 includes a bottom surface 13 disposed opposite the top surface 12. The front housing 3 includes a display surface 32 disposed away from the front surface 11. The angle α between the display surface 32 and the bottom surface 13 is an acute angle. The bottom surface 13 should be understood as the surface of the alarm clock 100 that contacts the placement surface 200 when the alarm clock 100 is placed on a table, the ground, or the like. Figure 5 Because the angle α between the bottom surface 13 and the display surface 32 is acute, when the alarm clock 100 is placed on the placement surface 200, the display surface 32 is tilted diagonally upward. This arrangement allows the user to better view the display portion 5 from various angles, such as standing or sitting, and thus obtain time information from the display portion 5 from the alarm clock 100.

[0062] Furthermore, the angle α between the bottom surface 13 and the display surface 32 is greater than or equal to 75 degrees and less than or equal to 85 degrees. For example, the angle α can be 75 degrees, 76 degrees, 77 degrees, 78 degrees, 79 degrees, 80 degrees, 81 degrees, 82 degrees, 83 degrees, 84 degrees, 85 degrees or any value therebetween. If the angle α is too large, the display surface 32 is close to a vertical plane, reducing the convenience of the user observing the display portion 5. If the angle α is too small, the inclination of the display surface 32 increases, making it difficult for the user to observe the display content of the display portion 5 in a sitting position. Therefore, the range of the angle α of this embodiment can meet the convenience of the user observing the display portion 5 at different angles.

[0063] In embodiments where the alarm clock 100 includes the lighting module 8 and the angle α between the display surface 32 and the bottom surface 13 is acute, the tilted display surface 32 allows the user to see the lighting module 8 even when viewing the alarm clock 100 from the front. This allows some of the light emitted by the lighting module 8 to exit the lighting module 8 directly without being reflected by the placement surface 200. This arrangement not only softens the light emitted by the lighting module 8 but also ensures its brightness.

[0064] Back to Figures 1 to 3 The main shell 1 includes a rear surface 15 arranged opposite to the front surface 11. In some optional embodiments, the main shell 1 also includes a speaker opening 16 arranged on the rear surface 15. The speaker opening 16 is connected to the first accommodating chamber 61. The alarm clock 100 also includes a speaker cover 9 and a speaker part. The speaker part is arranged in the first accommodating chamber 61. The speaker cover 9 is arranged in the speaker opening 16 and allows the sound of the speaker part to leave the first accommodating chamber 61. Compared with the embodiment in which the alarm clock 100 is ringed by a mechanical structure, the speaker module of this embodiment can ring electronically, so the ringtone is softer, avoiding excessively sharp alarm sounds causing discomfort to the user. In addition, since the display part 5 is provided on one side of the front surface 11, the speaker part is arranged closer to the rear side than the display part 5. This arrangement can reasonably utilize the internal space of the first accommodating chamber 61.

[0065] Optionally, the alarm clock 100 further includes a second inner shell portion 72. The second inner shell portion 72 is disposed in the first accommodating chamber 61 and surrounds the third accommodating chamber 63 of the alarm clock 100. That is, the third accommodating chamber 63 is actually disposed inside the first accommodating chamber 61. The second inner shell portion 72 includes an internal opening 721 that is connected to the third accommodating chamber 63. The internal opening 721 is disposed toward the speaker opening 16. The speaker portion is disposed in the third accommodating chamber 63 and is connected to the second inner shell portion 72. In other words, the second inner shell portion 72 of this embodiment is used to fix the speaker portion. Since the internal opening 721 is toward the speaker opening 16, the sound emitted from the speaker portion is reflected by the wall of the second inner shell portion 72 in the third accommodating chamber 63 and then leaves through the speaker opening 16. It can be seen that the third accommodating chamber 63 can improve the concentration of the sound emitted by the speaker portion, thereby ensuring the speaker effect.

[0066] Furthermore, in some optional embodiments, the second inner shell portion 72 includes a dividing unit 722. The dividing unit 722 divides the third accommodating cavity 63 into a first subspace 631 and a second subspace 632. The speaker portion is arranged in the first subspace 631. The alarm clock 100 also includes a power supply unit 10. The power supply unit 10 is arranged in the second subspace 632. In this embodiment, the third accommodating cavity 63 can be used to accommodate a plurality of different electronic control components and is divided by the dividing unit 722. This arrangement can reasonably utilize the third accommodating cavity 63 and improve the space utilization inside the alarm clock 100. In addition, the arrangement of the power supply unit 10 enables the alarm clock 100 to be used as a wireless device without the need for long-term use with a power adapter and a power cord, allowing the user to place the alarm clock 100 at any location.

[0067] The main housing portion 1 includes a side surface 14 connecting the top surface 12 and the front surface 11. Figure 6 , the raised unit 21 is arranged close to the side surface 14. The raised unit 21 is inclined on the side away from the top surface 12, and the angle γ with the adjacent side surface 14 is an obtuse angle. The button unit 41 is flush with the side of the raised unit 21 away from the top surface 12. In this way, the pressing surface of the button part 4 is inclined toward the side surface 14, and the side of the raised unit 21 away from the top surface 12 is also inclined toward the side surface 14. When the palm of the user is located on the side surface 14, the thumb extends toward the top surface 12, and the inclined button part 4 and the raised unit 21 can more conveniently enable the user to achieve the pressing operation of the button part 4 by bending the first knuckle of the thumb, and at the same time, the raised unit 21 will not restrict the pressing activity of the thumb.

[0068] Furthermore, the angle γ is greater than or equal to 95 degrees and less than or equal to 110 degrees. For example, the angle α can be 95 degrees, 96 degrees, 97 degrees, 98 degrees, 99 degrees, 100 degrees, 101 degrees, 102 degrees, 103 degrees, 104 degrees, 105 degrees, 106 degrees, 107 degrees, 108 degrees, 109 degrees, 110 degrees or any value therebetween. If the angle γ is too small, the inclination angle of the button portion 4 is small. For children with shorter fingers, it may be difficult to press. If the angle γ is too large, the pressing amplitude of the first knuckle of the thumb when pressing the button portion 4 increases. Therefore, the angle γ within this range enables the alarm clock 100 to be more adaptable to users of different palm sizes, and also enables the first knuckle of the thumb to operate the button portion 4 with a smaller movement amplitude, which is more ergonomically designed.

[0069] It should be noted that since the protrusion unit 21 is disposed close to the side surface 14, there are usually two side surfaces 14, namely Figure 6 The left or right side is shown, so this embodiment only defines the angular relationship between the protrusion unit 21 and the adjacent side surface 14. If the protrusion unit 21 is close to the left side surface 14, then the angle between the side of the protrusion unit 21 away from the top surface 12 and the left side surface 14 is an obtuse angle. If the protrusion unit 21 is close to the right side surface 14, then the angle between the side of the protrusion unit 21 away from the top surface 12 and the right side surface 14 is an obtuse angle.

[0070] Similarly, if Figure 5 As shown, in some optional embodiments, the side of the protrusion unit 21 facing away from the top surface 12 is tilted, and the angle β between it and the rear surface 15 is an obtuse angle. Furthermore, the button unit 41 is flush with the side of the protrusion unit 21 facing away from the top surface 12. In other words, both the button portion 4 and the side of the protrusion unit 21 facing away from the top surface 12 are tilted toward the rear surface 15. This allows the user's thumb to easily contact the button portion 4 and perform a pressing operation when the user's palm is placed on the rear surface 15.

[0071] Furthermore, the angle β is greater than or equal to 95 degrees and less than or equal to 110 degrees. For example, the angle β can be 95 degrees, 96 degrees, 97 degrees, 98 degrees, 99 degrees, 100 degrees, 101 degrees, 102 degrees, 103 degrees, 104 degrees, 105 degrees, 106 degrees, 107 degrees, 108 degrees, 109 degrees, 110 degrees or any value therebetween. If the angle β is too small, the inclination angle of the button portion 4 is small. For children with shorter fingers, it may be difficult to press. If the angle β is too large, the pressing amplitude of the first knuckle of the thumb when pressing the button portion 4 increases. Therefore, the angle β within this range enables the alarm clock 100 to be more adaptable to users of different palm sizes, and also enables the first knuckle of the thumb to operate the button portion 4 with a smaller movement amplitude, which is more ergonomically designed.

[0072] Optionally, the protrusion 21 is tilted away from the top surface 12, and the angle γ between the protrusion 21 and the adjacent side surface 14 and the angle β between the protrusion 21 and the rear surface 15 are both obtuse angles. In this way, the alarm clock 100 can meet the pressing comfort requirements of users with different gripping habits and different hand sizes.

[0073] It should be noted that the button unit 41 is flush with the side of the protrusion unit 21 away from the top surface 12. It can be understood that the button unit 41 is flush when not pressed, or the button unit 41 is flush when pressed to the extreme position, or the button unit 41 is flush at a certain moment during the pressing process.

[0074] Back to Figure 6 In some optional embodiments, the raised height D2 of the raised unit 21 is greater than or equal to 8 mm and less than or equal to 15 mm. For example, the height D2 can be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm or any value in between. When the height D2 increases, it may be difficult for a child user with a smaller palm to easily touch the surface of the button portion 4 with the thumb when holding the alarm clock 100. When the height D2 decreases, the thumb of a user with a larger palm needs to move more when pressing the button portion 4. The height D2 within this range can better meet the palm size requirements of most users, so that the alarm clock 100 is not only convenient for adults to operate, but also for children to operate.

[0075] Optionally, the size of the protrusion unit 21 gradually decreases in the extension direction of the protrusion unit 21 away from the top surface 12. In this embodiment, the size of the position where the protrusion unit 21 is connected to the surface of the upper shell 2 is larger than the size of the protrusion unit 21 near the button opening 22. In this way, the connection strength between the protrusion unit 21 and the top surface 12 is increased. When the alarm clock 100 is subjected to a falling impact, this arrangement can prevent the protrusion unit 21 from being broken by shear force or bending moment at the connection position of the top surface 12. In addition, the gradual reduction in the size of the protrusion unit 21 can not only make the alarm clock 100 have a more rounded appearance, but also avoid breakage caused by uneven strength at the position where the size suddenly changes.

[0076] The button part 4 is used to adjust the operation of the alarm clock 100, so it should actually be understood by default to include the electronic control unit 42. The electronic control unit 42 is arranged in the second accommodating cavity 62. When the button unit 41 moves toward the second accommodating cavity 62, the electronic control unit 42 is enabled, thereby achieving function adjustment. The electronic control unit 42 may be associated with the display part 5, that is, the adjustment of the display content of the display part 5 can be achieved through the button part 4. Alternatively, the electronic control unit 42 may be independent of the display part 5. For example, the electronic control unit 42 can be mute / play, then the button part 4 can be used to adjust whether the alarm clock 100 sounds or not, in which case the electronic control unit 42 may be independent of the display part 5. Of course, this application limits the specific functions that the electronic control unit 42 can achieve. Those skilled in the art can make adjustments as needed.

[0077] In some optional embodiments, the upper shell 2 also includes a sound receiving hole 23 connected to the second accommodating chamber 62. The alarm clock 100 also includes a microphone portion arranged in the second accommodating chamber 62. The button portion 4 is used to trigger the microphone portion on and off. When the button portion 4 is connected to the electronic control unit 42, the electronic control unit 42 enables the microphone portion. By providing the microphone portion and the sound receiving hole 23, the alarm clock 100 can realize voice input, so that young children who do not know how to operate buttons can adjust the alarm clock 100 through voice commands. In some optional embodiments, the electronic control unit 42 also allows the alarm clock 100 to have a voice conversation function, such as storing simple conversations so that young children can interact with the alarm clock 100 through the microphone portion. In other optional embodiments, the electronic control unit 42 also allows the alarm clock 100 to communicate with electronic devices such as mobile phones and tablets, so that young children can send voice messages to the parent's electronic device through the microphone portion, thereby realizing the communication function. This application is not limited to this.

[0078] As shown, there are multiple sound receiving holes 23, each located near opposing side surfaces 14. This arrangement allows the user to easily align the sound receiving hole 23 with their mouth, whether holding the alarm clock 100 with their left or right hand, to accurately receive voice commands. Of course, there can also be only one sound receiving hole 23, centrally located between the two side surfaces 14. This is not a limitation in the present application.

[0079] refer to Figure 3 and Figure 7 In some embodiments, the upper shell portion 2 includes a partition wall 24. The button opening 22 is provided on one side of the partition wall 24, and the second accommodating chamber 62 is provided on the other side of the partition wall 24. The partition wall 24 includes a connecting hole 241. The button portion 4 is provided on the button unit 41, and the fastener 411 penetrates the connecting hole 241 in the button opening 22 to enter the accommodating chamber, and is movably connected to the partition wall 24 so as to be able to move toward or away from the electronic control unit 42. By providing the partition wall 24, the partition wall 24 can limit the extreme position of the button portion 4, and prevent the button portion 4 from entering the second accommodating chamber 62 and being unable to be removed when subjected to excessive pressing force. In addition, the provision of the partition wall 24 can also increase the structural strength of the protruding protrusion unit 21, which is beneficial to reducing the wall thickness of the protrusion unit 21.

[0080] The latch 411 passes through the connecting hole 241 and enters the second accommodating cavity 62. The latch 411 and the connecting hole 241 can engage with each other when the key unit 41 moves away from the partition wall 24, thereby restricting the movement of the key unit 41. Of course, the key unit 41 can also be limited by a groove structure in the key opening 22, such as a concave-convex matching groove. This application is not limited to this.

[0081] The portion of the button unit 41 that passes through the connecting hole 241 can abut against the electronic control unit 42, thereby triggering the electronic control unit 42 when the button unit 41 moves toward the partition wall 24. In other embodiments, the partition wall 24 includes a trigger hole 242. The electronic control unit 42 is exposed from the trigger hole 242. The button portion 4 includes a trigger member 412 ( Figure 3 As shown). The trigger member 412 can pass through the trigger hole 242 to contact the electronic control unit 42. Among them, the trigger hole 242 is located in the middle of the partition wall 24. Since the trigger hole 242 is located in the middle of the partition wall 24, and the electronic control unit 42 needs to be exposed from the trigger hole 242, the electronic control unit 42 is actually also set in the middle position. When the user presses different positions of the button unit 41 (for example, to the left, to the right, etc.), the button unit 41 can also trigger the electronic control unit 42 near the middle. This setting method is conducive to improving the trigger sensitivity of the electronic control unit 42.

[0082] Optionally, the partition wall 24 further includes a reset hole 243 disposed around the trigger hole 242, and an abutment member 244 located between the reset hole 243 and the trigger hole 242. The abutment member 244 extends from the side of the partition wall 24 facing the key opening 22 toward the key unit 41. As shown in the figure, the reset hole 243 is disposed around the trigger hole 242, meaning that the strength of the partition wall 24 is reduced at the location where the reset hole 243 is disposed, while its elasticity is increased. The abutment member 244 is located between the reset hole 243 and the trigger hole 242, meaning that the abutment member 244 is disposed at a location on the partition wall 24 with greater elasticity. When the key unit 41 moves toward the partition wall 24, the abutment member 244 transmits the pressing force from the key unit 41 to the partition wall 24, causing the partition wall 24 to elastically deform toward the interior of the second accommodating cavity 62 under the influence of the abutment member 244. When the force from the button unit 41 disappears, the partition wall 24 returns to its original position under the action of elasticity, thereby pushing the button unit 41 back to its initial position.

[0083] As can be seen, the arrangement of the reset hole 243 and the abutment member 244 eliminates the need for an additional elastic reset member, such as a spring, within the protrusion unit 21 of the alarm clock 100. This arrangement not only reduces the number of components of the alarm clock 100, but also lowers the design cost of the alarm clock 100 and optimizes the space within the second accommodating cavity 62.

[0084] In order to balance the elasticity and support strength of the partition wall 24, the partition wall 24 may optionally include a reset area 245 ( Figure 7 The area within the red dashed box) and the connection area 246 ( Figure 7 The area outside the red dotted box is shown). The reset hole 243 and the trigger hole 242 are arranged in the reset area 245. The connection area 246 is arranged around the reset area 245. Among them, the thickness of the reset area 245 is less than the thickness of the connection area 246. In other words, the reset area 245 is used to provide an elastic pressing feel and reset the button part 4 through elastic deformation, so the thickness is smaller, which can improve the elasticity of the reset area 245. The connection area 246 is arranged around the reset area 245, so the connection area 246 is actually connecting the reset area 245 and the wall of the protruding unit 21, and the thickness here is larger. Therefore, when the connection area 246 is subjected to the force from the button part 4, the thickness of the connection area 246 can avoid the breakage of the connection position between the partition wall 24 and the protruding unit 21, which is beneficial to improve the service life of the alarm clock 100.

[0085] Optionally, the thickness of the partition wall 24 is greater than or equal to 8 mm and less than or equal to 25 mm. For example, the thickness of the partition wall 24 can be 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm, 25 mm or any value in between. If the thickness of the partition wall 24 is too large, the elasticity will decrease. When the user presses the button unit 41 and the button unit 41 contacts the partition wall 24, the strength of the partition wall 24 may cause the user to get feedback of rigid contact, which does not feel good. If the thickness of the partition wall 24 is too small, the strength is too small, which may cause the partition wall 24 to break when, for example, a child user presses the button part 4 hard. Therefore, the partition wall 24 within this thickness range can have good elasticity and also have excellent supporting strength.

[0086] It should be noted that, in the embodiment where the thickness of the reset region 245 is smaller than the thickness of the connection region 246 , the thickness of the reset region 245 and the thickness of the connection region 246 may also be respectively selected within the above-mentioned thickness range.

[0087] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
