Description

Technical Field

[0001] The utility model belongs to the technical field of law enforcement instruments, and in particular relates to a magnetic induction switch for law enforcement instruments. Background Art

[0002] The law enforcement device is a piece of evidence-gathering technology that police officers carry with them when performing their duties. It integrates real-time video and audio recording, photography, and video recording. It integrates the functions of video recording, photography, intercom, positioning, and storage. At the same time, it can transmit real-time video through 4G wireless. It can digitally record the dynamic and static on-site conditions during law enforcement, making it easier for public security officers to use it in law enforcement in various environments.

[0003] At present, the switch commonly used in law enforcement instruments is a push button switch. The push button switch not only has a short service life, but also requires a hole to be opened on the shell when it is installed, which results in poor waterproof effect of the law enforcement instrument. Public security officers will inevitably encounter rainy and snowy weather when on duty, so there are higher requirements for the waterproof performance of the law enforcement instrument. In order to solve the above problems, a magnetic induction switch for a law enforcement instrument is now provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a law enforcement instrument magnetic induction switch, which controls the switch of the law enforcement instrument by controlling the distance between the Hall sensor and the magnet. It is a non-contact switch. The life of this type of switch is several times longer than that of a traditional push-type switch. And because the driving switch does not need to contact the circuit board inside the shell, there is no need to open a hole at the position where the driving switch is installed on the shell, so it can also achieve waterproofing.

[0006] To achieve the above-mentioned purpose, the utility model proposes a magnetic induction switch for a law enforcement instrument. The law enforcement instrument includes a shell, a circuit board is installed inside the shell, and the magnetic induction switch includes a Hall sensor and a driving switch for triggering the Hall sensor.

[0008] Furthermore, a first slide groove is provided on one side of the shell, and a second slide groove is provided at the bottom of the first slide groove.

[0009] The driving switch includes two first sliders sliding in the first sliding groove, a driving plate fixedly connected between the two first sliders, a second slider fixed on the driving plate, the second slider sliding in the second sliding groove, an installation groove is provided on the second slider, and the magnet is installed in the installation groove.

[0010] Furthermore, a plurality of convex strips are provided on one side of the driving plate located at the outside.

[0011] Furthermore, a first limiting plate and a second limiting plate are fixed on the shell, and the first limiting plate and the second limiting plate correspond to two ends of the first sliding groove respectively.

[0012] Furthermore, when one of the first sliding blocks slides to below the second limiting piece, the distance between the magnet and the Hall sensor is shorter.

[0013] Furthermore, when one of the first sliding blocks slides below the first limiting piece, the magnet moves away from the Hall sensor.

[0014] Furthermore, rubber sheets are fixed to the bottoms of the first limiting piece and the second limiting piece.

[0015] Furthermore, the first limiting piece and the second limiting piece are elastic pieces.

[0016] Furthermore, a semicircular protrusion is fixed below the first limiting piece and the second limiting piece, and a groove is formed above the first sliding block.

Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more schemes or examples.

[0030] The embodiment of the utility model provides a magnetic induction switch for a law enforcement instrument, the law enforcement instrument comprises a housing 1, such as Figure 1 , Figure 2 As shown, a circuit board 2 is installed inside the shell 1, and the magnetic induction switch includes a Hall sensor 21 and a driving switch 3 for triggering the Hall sensor 21. The Hall sensor 21 is installed on the circuit board 2 and can be used to control the power on and off of the law enforcement instrument. The driving switch 3 is installed outside the shell 1, and the driving switch 3 is slidably connected to the shell 1.

[0031] A first slide groove 11 is provided on one side of the shell 1, a second slide groove 12 is provided at the bottom of the first slide groove 11, a first limiting piece 13 and a second limiting piece 14 are fixed on the shell 1, and the first limiting piece 13 and the second limiting piece 14 correspond to the two ends of the first slide groove 11 respectively.

[0032] The driving switch 3 includes two first sliding blocks 31 sliding in the first sliding groove 11, and a driving plate 32 is fixedly connected between the two first sliding blocks 31. A plurality of convex strips 36 are provided on the side of the driving plate 32 located outside. By providing the convex strips 36, the friction between the hand and the driving switch 3 can be increased to avoid slipping when pushing the driving switch 3.

[0033] A second slider 33 is fixed on the driving plate 32. The second slider 33 slides in the second slide groove 12. A mounting groove 34 is provided on the second slider 33. A magnet 35 is fixedly installed in the mounting groove 34. When one of the first sliders 31 slides to the bottom of the second limit plate 14, the distance between the magnet 35 and the Hall sensor 21 is short. After the Hall sensor 21 senses the magnetic force of the magnet 35, it controls the law enforcement device to turn on.

[0034] Preferably, rubber sheets are fixed to the bottom of the first limiting piece 13 and the second limiting piece 14 , so as to limit the driving switch 3 when the first sliding block 31 slides to the bottom thereof.

[0035] Preferably, the first limiting piece 13 and the second limiting piece 14 can be elastic pieces, such as Figure 3, Figure 4 As shown, a semicircular protrusion 15 is fixed below the first limiting plate 13 and the second limiting plate 14, and a groove 37 is opened above the first slider 31. When the corresponding first limiting plate 13 or the second limiting plate 14 can slide on the first slider 31, the protrusion 15 can slide into the groove 37 to limit the driving switch 3.

[0036] When in use, the driving plate 32 is pushed to control one of the first sliders 31 to slide to the bottom of the first limit plate 13. At this time, the magnet 35 is away from the Hall sensor 21, thereby controlling the law enforcement device to be turned off. The driving plate 32 is pushed to control one of the first sliders 31 to slide to the bottom of the second limit plate 14. At this time, the distance between the magnet 35 and the Hall sensor 21 is shortened, thereby controlling the law enforcement device to be turned on.

[0037] The magnetic induction switch of the utility model controls the switch of the law enforcement instrument by controlling the distance between the Hall sensor 21 and the magnet 35. It is a non-contact switch. The life of this type of switch is several times longer than that of a traditional push-type switch. And because the drive switch 3 does not need to contact the circuit board 2 inside the shell 1, the position where the drive switch 3 is installed on the shell 1 does not need to be opened, so it can also achieve waterproofing.
