For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] FIG1 is a schematic diagram of a wearable alarm device according to an embodiment of the present invention, which can be worn on a wrist and triggered to output an alarm signal. The wearable alarm device according to this embodiment includes a first housing 10, a second housing 20, and an elastic connecting portion 30. The first housing 10 and the second housing 20 can each be made of a hard material, and the elastic connecting portion 30 is made of an elastic material (e.g., metal, hard plastic, etc.).

[0031] As shown in Figure 2, the first shell 10 includes a first cavity, and a trigger switch 15 and an alarm component for generating a local alarm signal are provided in the first cavity. Specifically, the local alarm signal can be sound, light, etc. After the trigger switch 15 is triggered, a local alarm signal is generated by the alarm component, which can deter illegal infringers and remind people around the wearable alarm that illegal infringements or emergencies have occurred. The trigger switch 15 can be a push-type switch. After the trigger switch 15 is connected to the circuit, it can output a trigger level (for example, a high level) when pressed. The trigger switch 15 can adopt conventional devices in this field, which will not be described here.

[0032] As shown in FIG3 , the second housing 20 includes a second cavity, in which a main control circuit board 23 and a battery 24 are disposed. The main control circuit board 23 is composed of a printed circuit board (PCB) integrated with electronic components, and the battery 24 is used to power the main control circuit board 23. The main control circuit board 23 has a control circuit for controlling the alarm component to generate a local alarm signal. The trigger switch 15 and the alarm component in the first housing 10 are electrically connected to the control circuit, and the control circuit outputs an electrical signal to the alarm component after receiving the trigger level of the trigger switch 15, causing the alarm component to generate a local alarm signal. The main control circuit board 23 and the battery 24 can both adopt conventional results in the field and will not be described in detail here.

[0033] The elastic connecting part is C-shaped, and the first shell 10 and the second shell 20 are respectively connected to the two ends of the elastic connecting part 30, and a semi-enclosed wearing space is formed between the first shell 10, the second shell 20 and the elastic connecting part 30. The trigger switch and the alarm component in the first shell are respectively electrically connected to the main control circuit board 23 in the second shell through cables attached to the surface of the elastic connecting part 30.

[0034] When the elastic connection part 30 is in a natural state, the distance between the free ends of the first shell 10 and the second shell 20 is smaller than the distance between the two ends of the elastic connection part 30. When worn, the wrist can pass through the opening between the free ends of the first shell 10 and the second shell 20 to enter the wearing space. When the wrist passes through the opening between the free ends of the first shell 10 and the second shell 20, the elastic connection part 30 can produce elastic deformation, so that the size of the above-mentioned opening becomes larger to facilitate the wrist to enter the wearing space; after the wrist enters the wearing space, under the action of the elastic restoring force of the elastic connection part 30, the opening between the free ends of the first shell 10 and the second shell 20 becomes smaller, and at the same time, the first shell 10 and the second shell 20 clamp the wrist, making it difficult for the above-mentioned wearable alarm to fall off the wrist.

[0035] The wearable alarm described above connects a first housing 10, which houses a trigger switch 15 and an alarm assembly, and a second housing 20, which houses a main control circuit board 23 and a battery 24, via a C-shaped elastic connection 30. The elastic force of the elastic connection 30 allows the first and second housings 10, 20 to clamp around the wrist, providing an alarm while greatly facilitating wear. Furthermore, by locating the alarm assembly and trigger switch in the first housing 10 and the main control circuit board 23 and battery 24 in the second housing 20, the entire wearable alarm can still function properly even if a small amount of water enters the first housing 10.

[0036] In one embodiment of the present invention, the outer side of the elastic connection portion 30 has a wire groove 31, which is arranged along the length of the elastic connection portion 30. The wire groove 31 is used to embed the cable that electrically connects the trigger switch 15 and the alarm component to the main control circuit board 23 into the wire groove 31. Accordingly, the first housing 10 and the second housing 20 each have a wire hole corresponding to the wire groove 31 to facilitate the cable in the wire groove 31 to pass through the first housing 10 and the second housing 20. This wire groove structure can prevent the cable from being pulled and causing the connection with the trigger switch 15, the alarm component, and the main control circuit board 23 to become loose.

[0037] As shown in Figure 5, in one embodiment of the present invention, in addition to the first shell 10, the second shell 20 and the elastic connecting portion 30, the wearable alarm further includes a protective cover 41 made of a relatively soft elastic material (such as silicone), the protective cover including a first wrapping portion for wrapping the first shell 10, a second wrapping portion for wrapping the elastic connecting portion 30, and a third wrapping portion for including the second shell 20. The shapes and sizes of the first wrapping portion, the second wrapping portion, and the third wrapping portion are respectively the same as the shapes and sizes of the first shell 10, the elastic connecting portion 30, and the second shell 20, and the first wrapping portion, the second wrapping portion, and the third wrapping portion are integrally formed. Through the protective cover 41, on the one hand, the first shell 10 and the second shell 20 can be included, thereby improving the consistency of the overall shape of the wearable alarm, and on the other hand, the wearing comfort can also be improved.

[0038] In one embodiment of the present invention, the outer side surface of the first shell 10 (i.e., the surface facing away from the second shell 20) has a plurality of first through holes 111 corresponding to the alarm components, and correspondingly, the outer side surface of the first wrapping portion of the protective cover 41 has a plurality of second through holes 411 corresponding to the first through holes 111, that is, when the first shell 10 is assembled to the first wrapping portion, the alarm components installed in the first shell 10 are exposed through the first through holes 111 and the second through holes 411, respectively, so as to output a local alarm signal. The inner side surface of the third wrapping portion of the protective cover 41 has a third through hole 412. During assembly, the first shell 10 is inserted into the first wrapping portion through the third through hole 412 and the second wrapping portion, while the elastic connecting portion 30 is located in the second wrapping portion, the second shell 20 is located in the third wrapping portion, and the bottom of the second shell 20 is exposed in the third through hole 412. The above structure can further improve the surface consistency of the wearable alarm.

[0039] Furthermore, a cover plate 42 may be provided, the shape and size of which match those of the third through hole 412. After the protective cover 41 is fitted over the first shell 10, the second shell 20, and the elastic connector 30, the cover plate 42 may be positioned over the third through hole 412 to enhance the wearable alarm's dust and water resistance. A snap-fit ​​structure may be provided around the third through hole 412 and between the cover plate 42 to enhance the stability of the connection between the cover plate 42 and the protective cover 41.

[0040] In addition, a raised pressing portion 113 may be provided on the outer surface of the first housing 10. This pressing portion 113 is connected to other portions of the outer surface of the first housing 10 via an elastic arm, and the trigger switch 15 is located directly below the pressing portion. Accordingly, the protective cover 41 has a raised portion 413 corresponding to the pressing portion 113, so that the trigger switch 15 can generate a trigger signal by pressing the raised portion 413. Of course, in actual applications, other structures can also be used to generate a trigger signal for the trigger switch 15, which will not be described in detail here.

[0041] In one embodiment of the present invention, the cable includes a first connecting wire, and the alarm assembly includes a sound playback device 141 electrically connected to the main control circuit board 23 via the first connecting wire. For example, the sound playback device can be a buzzer, and the sound playback device can emit sound under the control of the main control circuit board 23. Accordingly, the first housing 10 includes a cover 142 mounted at the first through hole 111 corresponding to the sound playback device 141, and the cover 142 is exposed through one of the second through holes 411 of the protective cover 41. To facilitate sound transmission, the cover 142 may have multiple holes. In addition, a waterproof and breathable film may be provided below the cover 142 to enhance the waterproof performance of the wearable alarm.

[0042] In one embodiment of the present invention, the cable includes a second connecting wire, and the alarm assembly includes a heat sink substrate 134, a reflector cup 132, a transparent lampshade 133, and a light-emitting element 131 electrically connected to the main control circuit board 23 via the second connecting wire. Specifically, the light-emitting element 131 may be a high-power LED lamp, for example. The light-emitting element 131 passes through the reflector cup 132 and is fixed to the heat sink substrate 134. The transparent lampshade 133 is positioned on top of the reflector cup 132 and is exposed sequentially through a first through hole 111 and a second through hole 411. This allows light emitted by the light-emitting element 131 to be dissipated to the outside, ensuring relatively high light intensity.

[0043] In practical applications, the alarm component in the first housing 10 may include both the light emitting body 131 and the sound playing device, or may include only one of the light emitting body 131 and the sound playing device.

[0044] As shown in FIG2 , in one embodiment of the present invention, the first housing 10 includes a first upper cover 11 and a first lower cover 12. A first cavity is formed between the first upper cover 11 and the first lower cover 12, specifically, the trigger switch 15 and the alarm assembly are located between the first upper cover 11 and the first lower cover 12. The elastic connector 30 is integral with the first lower cover 12. The first lower cover 12 has a plurality of standoffs 121 disposed toward the first upper cover 11 and distributed along the circumference of the first lower cover 12. The first upper cover 11 has mounting holes 112 corresponding to the standoffs 121. The first upper cover 11 is secured to the first lower cover 12 via screws threaded through the mounting holes 112 and connected to the standoffs 121. In practice, the elastic connector 30 may be integral with the first upper cover 11, or it may be separate from the first upper cover 11 and the first lower cover 12 and secured to the first upper cover 11 or the first lower cover 12 via adhesive, snaps, screws, or the like. Of course, the first shell 10 may also adopt other existing structures, as long as it can provide protection for the trigger switch 15 and the alarm component, which will not be described in detail here.

[0045] As shown in Figure 3, in one embodiment of the present invention, the second housing 20 includes a second upper cover 21 and a second lower cover 22 that interlock together. The second cavity is formed between the second upper cover 21 and the second lower cover 22, that is, the main control circuit board 23 and the battery 24 are located between the second upper cover 21 and the second lower cover 22. Specifically, the second upper cover 21 has a plurality of circumferentially distributed hooks 211, and the second lower cover 22 has a plurality of corresponding latches 222. The second upper cover 21 and the second lower cover 22 are fastened together by the hooks 211 hooking onto the latches 222. Of course, in actual applications, the second upper cover 21 and the second lower cover 22 can also be fixed together by other means, such as screws.

[0046] As shown in FIG4 , the end of the elastic connection portion 30 connected to the second housing 20 has a protrusion 32, and the protrusion 32 has a first pin hole 321, which extends through the left and right surfaces of the protrusion. Correspondingly, the second lower cover 22 or the second upper cover 21 has two parallel ear plates 221 on the end facing the elastic connection portion 30, with a mounting slot formed between the two ear plates 221. Each ear plate 221 has a second pin hole 2211, and the elastic connection portion 30 is embedded in the mounting slot with the protrusion 32 and is hinged to the second housing 20 via a pin 25 that passes through the first and second pin holes 321, 2211. That is, the second housing 20 can rotate relative to the elastic connection portion 30, thereby facilitating adjustment of the distance between the first and second housings 10, 20 to accommodate different wearers' wrists. Of course, the rotational damping between the second housing 20 and the elastic connection portion 30 is large to ensure stable wearing.

[0047] In one embodiment of the present invention, the main control circuit board 23 may also include a positioning module and a wireless communication module. Upon receiving a trigger signal from the trigger switch 15, the main control circuit board obtains location information from the positioning module and transmits this location information via the wireless communication module, for example, to a mobile phone associated with the wearable alarm. This allows for remote alarming. Both the positioning module and the wireless communication module can employ existing solutions in the art and will not be further described here.

[0048] The battery 24 within the second housing 20 can be a rechargeable battery. Accordingly, the main control circuit board 23 includes a charging circuit. The inner surface of the second housing 20 includes a charging port 212, and the charging port 212 and the rechargeable battery are electrically connected to the charging circuit. This structure facilitates continuous use of the wearable alarm. Both the charging port 212 and the charging circuit are conventional in the art and will not be further described here.

[0049] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
