Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-5As shown, this utility model provides an alarm device based on the Bluetooth detection principle, including: a watch frame 2, a Bluetooth module 10, a microcontroller 11, a battery 13, and a speaker 4 fixedly connected to the inner top of the watch frame 2, an alarm component 8 fixedly connected to the inner top of the watch frame 2 at the position of the battery 13, an alarm light 3 fixedly connected to the top of the watch frame 2 near the edge, a cover plate 14 fixedly connected to the inner surface of the watch frame 2, and multiple through holes 12 evenly opened at the bottom of the cover plate 14; the alarm component 8 includes a micro motor 801 and a support frame 808, the top of the micro motor 801 is fixedly connected to the inner top of the watch frame 2, the output end of the micro motor 801 is fixedly connected to a rotating shaft 802, the outer surface of the rotating shaft 802 is fixedly connected to a cam 803, and the inner surface of the support frame 808... Multiple striking rods 804 are connected to the bottom of the watch frame 2. A connecting plate 807 is fixedly connected between the tops of the multiple striking rods 804. Rubber pads 805 are fixedly connected to the bottoms of the multiple striking rods 804. Springs 806 are fitted on the outer surfaces of the multiple striking rods 804. The top of the support frame 808 is fixedly connected to the inner top of the watch frame 2. The position of the cam 803 matches the position of the connecting plate 807. Multiple springs 806 are located between the connecting plate 807 and the support frame 808. The positions of the multiple striking rods 804 and multiple through holes 12 match. The micro controller 11 is electrically connected to the warning light 3, speaker 4, Bluetooth module 10, micro motor 801 and battery 13. A speaker hole 6 is opened on the front surface of the watch frame 2. The position of the speaker 4 matches the position of the speaker hole 6.

[0026] The overall effect of Embodiment 1 is that, during use, the watch strap 1 can be used to fix the watch frame 2 on the wrist. Both adults and children can wear the watch frame 2 on their arms, and the two Bluetooth modules 10 can be paired and connected. The two Bluetooth modules 10 are of the same model and compatible. When the distance between the child and adult exceeds the effective connection distance or detection range of the Bluetooth module 10, the Bluetooth module 10 will send a signal to the microcontroller 11. After receiving the alarm signal from the Bluetooth module 10, the microcontroller 11 will control the speaker 4 and the warning light 3 to respond. The sound from the speaker 4 will be emitted through the speaker hole 6 to provide an alarm. Simultaneously, the micro motor 801 will drive the rotating shaft 802 to rotate, causing the cam 803 to rotate synchronously. When the cam 80... When the protrusion of cam 803 rotates to the bottom, it applies downward pressure to the connecting plate 807, causing the spring 806 to compress. This causes the striking rod 804 to move downwards to the outside along the support frame 808 and the through hole 12. When the protrusion of cam 803 rotates to the top, the spring 806 causes the striking rod 804 to move upwards along the support frame 808. Driven by the micro motor 801, the striking rod 804 moves up and down reciprocally, causing the striking rod 804 to strike the wrist as an alarm. During the strike, the rubber pad 805 increases the comfort of the wrist. Through the triple alarm of sound, vision and touch, children and adults are promptly alerted to the distance being too far. The battery 13 can provide power to the electrical components.

[0027] Example 2, as Figures 1-5 As shown, the top of the watch frame 2 is provided with a placement slot 9, the bottom of the placement slot 9 is provided with a label card 5, the inner surface of the placement slot 9 is provided with a transparent plate 7, and both outer surfaces of the watch frame 2 are provided with watch straps 1.

[0028] The effect achieved by the entire embodiment 2 is that, before wearing the tag, the adult's contact information and address can be written on the child's tag card 5, and then the placement slot 9 can be sealed by the transparent plate 7. It can be fixed by means of glue, snap-fit ​​or bolts to protect the tag card 5. Thus, if the child gets lost, he can also seek help from passers-by through the tag card 5, which is highly practical.

[0029] Working principle: During use, the watch strap 1 can be used to fix the watch frame 2 on the wrist. Both adults and children can wear the watch frame 2 on their arms. When wearing the watch, the adult's contact information and address can be written on the child's tag card 5. Then, the placement slot 9 is sealed by the transparent plate 7, and the two Bluetooth modules 10 are paired and connected. The two Bluetooth modules 10 are of the same model and are compatible. When the distance between the child and the adult exceeds the effective connection distance of the Bluetooth module 10, the Bluetooth module 10 will send a signal to the micro controller 11. After receiving the alarm signal sent by the Bluetooth module 10, the micro controller 11 will control the speaker 4 and the warning light 3 to respond. The sound from the speaker 4 will be emitted through the speaker hole 6 to provide an alarm. At the same time, the micro motor 801 will drive the rotating shaft. Rotation of 802 causes cam 803 to rotate synchronously. When the protrusion of cam 803 rotates to the bottom, it applies downward pressure to connecting plate 807, causing spring 806 to compress. This causes the striking rod 804 to move downwards to the outside along support frame 808 and through hole 12. When the protrusion of cam 803 rotates to the top, spring 806 causes striking rod 804 to move upwards along support frame 808. Driven by micro motor 801, striking rod 804 moves up and down reciprocally, causing striking rod 804 to strike the wrist as an alarm. During striking, rubber pad 805 increases wrist comfort. Through sound, visual and tactile alarms, children and adults are promptly alerted to the distance.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
