Description

Technical Field

[0001] The present invention relates to the technical field of charging devices, and more particularly, to an automatic shutdown charging device for law enforcement equipment based on NFC tags. Background Art

[0002] Law enforcement equipment refers to various tools and technical devices used to support and enhance the ability of administrative law enforcement personnel to perform their duties. To improve law enforcement efficiency, safeguard public safety, and ensure the transparency and legality of the law enforcement process, law enforcement personnel carry law enforcement equipment in their daily work. To record the situation at the scene in real time, law enforcement equipment must be equipped with cameras that meet video recording capabilities. To enhance video clarity in low-light or no-light environments, cameras on law enforcement equipment are equipped with thermal imaging capabilities.

[0003] For the sake of efficiency, compliance and fairness, and to ensure the comprehensiveness and non-tamperability of information during the law enforcement process, the thermal imaging camera will be automatically started after the law enforcement equipment is turned on. In order to reduce the power consumption of the law enforcement equipment and extend the standby time of the law enforcement equipment, the law enforcement equipment does not need to be equipped with a display screen. The thermal imaging camera uses a USB interface thermal imaging camera. By inserting the USB data cable into the USB interface to connect the reading device, the reading device reads the image captured by the thermal imaging camera. The USB interface can not only provide data reading but also provide power resource transmission.

[0004] However, when the thermal imaging camera is connected to the reading device via a USB port, the power management system of the law enforcement device fails to effectively strike the correct balance between charging and powering the reading device. When the thermal imaging camera is turned on and connected to the reading device via a USB port, it occupies the power resources that should be used for charging, resulting in the law enforcement device being unable to charge effectively even if the socket charger is plugged in. Summary of the Invention

[0005] The NFC tag-based automatic shutdown and charging device for law enforcement equipment provided by the present invention aims to solve the problem that, in existing automatic shutdown and charging devices for law enforcement equipment, when a thermal imaging camera is connected to a reading device via a USB interface, the power management system of the law enforcement equipment fails to effectively strike the correct balance between charging and powering the reading device. When the thermal imaging camera is turned on and connected to the reading device via a USB interface, it occupies the power resources that should be used for charging, resulting in the law enforcement equipment being unable to be effectively charged even if a socket charger is plugged in.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an automatic shutdown and charging device for law enforcement equipment based on NFC tags, comprising a support base, a positioning groove is provided on the support base, the positioning groove is used to support the law enforcement instrument body, a charging connector is provided in the positioning groove, the charging connector is used to charge the law enforcement instrument body, and an NFC tag is provided in the support base.

[0007] In a preferred embodiment, two positioning clips are provided in the positioning groove, and the two positioning clips are fixed by the same connecting rod, and the positioning clips are used to clamp and position the body of the law enforcement instrument.

[0008] In a preferred embodiment, a dehumidification mechanism is provided in the positioning groove, and the dehumidification mechanism includes a hard tube 1, on which a nozzle 1 is fixedly provided, and the nozzle 1 is arranged toward the charging port.

[0009] In a preferred embodiment, a dust removal mechanism is provided in the positioning groove, and the dust removal mechanism includes a second hard tube, on which a second nozzle is fixedly provided, and the second nozzle is arranged toward the charging port.

[0010] In a preferred embodiment, the dehumidification mechanism also includes a bellows 1, the top end of the bellows 1 is fixedly connected to the bottom end of the hard tube 1, the nozzle 1 is slidingly arranged with the bottom of the positioning clamp, a guide plate 1 is rotatably arranged on the hard tube 1, a guide plate 1 is fixedly arranged in the positioning groove, a guide wheel 1 is rotatably arranged on the hard tube 1, and the guide wheel 1 is adapted to the guide plate 1.

[0011] In a preferred embodiment, the dust removal mechanism also includes a bellows 2, the top end of the bellows 2 is fixedly connected to the bottom end of the hard tube 2, the nozzle 2 is slidingly arranged with the bottom of the positioning clamp, a guide plate 2 is rotatably arranged on the hard tube 2, a guide plate 2 is fixedly arranged in the positioning groove, and a guide wheel 2 is rotatably arranged on the hard tube 2, and the guide wheel 2 is adapted to the guide plate 2.

[0012] In a preferred embodiment, a linear drive mechanism is provided in the positioning groove, and the linear drive mechanism includes a rotary driver, which is fixed in the positioning groove, a screw rod is fixed on the output shaft of the rotary driver, a connecting seat is fixed on the positioning clamp, and the screw rod is threadedly connected to the connecting seat.

[0013] In a preferred embodiment, a guide seat is fixedly arranged in the positioning groove, a sliding groove is opened on the guide seat, an auxiliary seat is fixedly arranged on the positioning clamp, the auxiliary seat is slidably arranged in the sliding groove, a guide shaft is fixedly arranged on the inner wall of the sliding groove, and the auxiliary seat and the guide shaft are slidably arranged.

[0014] Place the body of the body camera in the positioning slot and insert the charging connector into the charging port. The NFC antenna will receive the command programmed in the NFC tag and shut down the body of the body camera. Then you can insert the charging connector into the charging port to charge the body of the body camera. Without changing the existing hardware architecture, it provides users with a simple and efficient method to manage and optimize the power usage of law enforcement equipment, especially when high-power consumption peripherals are involved.

[0015] Place the body of the law enforcement device between the two positioning clamps. The elastic side of the positioning clamps clamps the body of the law enforcement device under the action of elastic force. Then start the rotation driver. The rotation of the output shaft of the rotation driver drives the screw to rotate. The screw is threadedly connected to the connecting seat to drive the positioning clamp to move downward as a whole. During the vertical downward movement of the positioning clamp, the charging connector is connected to the charging port to charge the body of the law enforcement device.

[0016] Start the fan, and warm air will be ejected from the exhaust end of the fan. The warm air is guided by the bellows 1 and the hard tube 1, and finally sprayed into the charging port through the nozzle 1, thereby accelerating the evaporation of water in the charging port. When the water in the charging port is evaporated, the body of the law enforcement instrument is driven to move vertically downward. During the vertical downward movement of the body of the law enforcement instrument, since the guide plate 1 is inclined, the guide wheel 1 is rollingly connected to the guide plate 1. Under the guidance of the guide plate 1, the nozzle 1 and the bottom of the positioning clamp are horizontally moved, thereby avoiding interference caused by the nozzle 1 when the charging connector is inserted into the charging port.

[0017] Start the exhaust fan, and the exhaust end of the exhaust fan extracts gas to form negative pressure. The negative pressure airflow is guided by the bellows 2 and the hard tube 2, and finally the negative pressure airflow is connected to the charging port through the nozzle 2, thereby extracting the particulate impurities in the charging port. When the particulate impurities in the charging port are cleaned, the law enforcement instrument body is driven to move vertically downward. In the process of the vertical downward movement of the law enforcement instrument body, due to the inclined setting, the guide wheel 2 is rollingly connected to the guide plate 2. Under the guidance of the guide plate 2, the nozzle 2 and the bottom of the positioning clamp are horizontally moved to avoid interference caused by the nozzle 2 when the charging connector is inserted into the charging port.

[0018] An automatic shutdown charging device for law enforcement equipment based on NFC tags is used to charge law enforcement equipment with NFC tags. The law enforcement equipment with NFC tags includes a law enforcement instrument body, a USB thermal imaging camera is provided in the law enforcement instrument body, and a charging port is provided on the law enforcement instrument body, and the charging connector is adapted to the charging port.

[0019] In a preferred embodiment, an NFC antenna is provided in the body of the body camera, and the NFC antenna is used to read the information of the NFC tag.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention sets an NFC antenna and an NFC tag. When the charging port is connected to the charging connector to charge the body of the law enforcement instrument, the NFC antenna obtains the shutdown command stored in the NFC tag and automatically shuts down the body of the law enforcement instrument through NFC technology, which can effectively charge the law enforcement equipment. It can also provide users with a simple and efficient way to manage and optimize the power usage of law enforcement equipment without changing the existing hardware architecture.

DETAILED DESCRIPTION

[0030] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Refer to the instruction manual Figure 1 and Figure 2 The automatic shutdown charging device for law enforcement equipment based on NFC tags includes a support base 1, a positioning groove 11 is provided on the support base 1, the positioning groove 11 is used to support the law enforcement instrument body 2, a charging connector 12 is provided in the positioning groove 11, the charging connector 12 is used to charge the law enforcement instrument body 2, and an NFC tag 4 is provided in the support base 1.

[0032] It should be noted that the automatic shutdown charging device is used to charge law enforcement equipment with an NFC tag. The law enforcement equipment with an NFC tag includes a body 2 of the law enforcement device, which is equipped with a USB thermal imaging camera 21 and a charging port 22. The charging connector 12 is compatible with the charging port 22. The body 2 of the law enforcement device is equipped with an NFC antenna 3, which is used to read information from the NFC tag 4.

[0033] It should be noted that the instruction stored in NFC tag 4 is to shut down the body camera 2. The information stored in NFC tag 4 is usually a URL or other type of NDEF message. Programming can be completed through a dedicated NFC programming tool or application. These tools allow you to write data to a blank, writable NFC tag. The body camera 2 has an NFC tag 4. NFC tag 4 can recognize the information in the body camera 2 and issue corresponding instructions. The cooperation between NFC tag 4 and the body camera 2 is a mature existing technology and will not be elaborated on here.

[0034] The specific implementation scenario is as follows: the body of the law enforcement device 2 is placed in the positioning slot 11, the charging connector 12 is inserted into the charging port 22, and the NFC antenna 3 obtains the instruction programmed in the NFC tag 4, completing the shutdown of the body of the law enforcement device 2. At this time, the body of the law enforcement device 2 can be charged by inserting the charging connector 12 into the charging port 22. Without changing the existing hardware architecture, it also provides users with a simple and efficient method to manage and optimize the power usage of law enforcement equipment, especially when high-power consumption peripherals are involved.

[0035] Refer to the instruction manual Figures 3 to 6In order to facilitate the automatic connection between the charging connector 12 and the charging port 22 and improve the user experience, specifically, two positioning clamps 5 are provided in the positioning groove 11. The two positioning clamps 5 are fixed by the same connecting rod 51. The positioning clamps 5 are used to clamp and position the law enforcement instrument body 2. A linear drive mechanism 6 is provided in the positioning groove 11. The linear drive mechanism 6 includes a rotation driver 61. The rotation driver 61 is fixed in the positioning groove 11. A screw 62 is fixed on the output shaft of the rotation driver 61. A connecting seat is fixed on the positioning clamp 5. The screw 62 is threadedly connected to the connecting seat. A guide seat is fixed in the positioning groove 11. A slide groove is provided on the guide seat. An auxiliary seat is fixed on the positioning clamp 5. The auxiliary seat is slidably set in the slide groove. A guide shaft is fixed on the inner wall of the slide groove. The auxiliary seat and the guide shaft are slidably set.

[0036] It should be noted that the rotary driver 61 is configured as a motor, and the output shaft of the motor is fixed to the screw 62. The outer fixed sleeve of the guide shaft is provided with anti-slip rubber, which can increase the friction between the connecting seat and the guide shaft. The side wall of the positioning clamp 5 is elastic. After the law enforcement instrument body 2 is placed between the two positioning clamps 5, the law enforcement instrument body 2 is clamped under the action of the elastic side. The principle is similar to that of an "elastic clip". As a mature existing technology, it will not be elaborated here. Flexible support cotton is fixedly provided on the inner side of the positioning clamp 5, and the flexible support cotton is used to contact the outer side of the law enforcement instrument body 2.

[0037] It should also be noted that the law enforcement instrument body 2 is placed between the two positioning clamps 5, and the elastic side of the positioning clamp 5 is used to clamp the law enforcement instrument body 2 under the action of elastic force, and then the rotation driver 61 is started, and the rotation of the output shaft of the rotation driver 61 drives the screw rod 62 to rotate. The screw rod 62 is threadedly connected to the connecting seat to drive the positioning clamp 5 to move downward as a whole. During the vertical downward movement of the positioning clamp 5, the charging connector 12 is connected to the charging port 22 to realize charging of the law enforcement instrument body 2.

[0038] Refer to the instruction manual Figures 3 to 6Law enforcement officers are on duty in a variety of severe weather and environments to ensure public safety and social order. For example, during heavy rainfall, there may be risks of secondary disasters such as floods and mudslides. Law enforcement officers need to maintain traffic order, rescue trapped people and protect property safety in such an environment. When law enforcement officers are on duty in such an environment, there will be water droplets in the charging port 22. If the charging port 22 is connected to the charging connector 12, the law enforcement instrument body 2 cannot be charged, and it may even cause a short circuit and damage to the law enforcement instrument body 2. In order to solve the above problems, a dehumidification mechanism 7 is specifically provided in the positioning groove 11. The dehumidification mechanism 7 includes a hard tube 71, and a nozzle 72 is fixedly provided on the hard tube 71. The nozzle 72 is arranged toward the charging port 22. The dehumidification mechanism 7 also includes a bellows 73, the top end of the bellows 73 is fixedly connected to the bottom end of the hard tube 71, the nozzle 72 is slidably arranged with the bottom of the positioning clamp 5, a guide plate 75 is rotatably arranged on the hard tube 71, a guide plate 75 is fixedly arranged in the positioning groove 11, and a guide wheel 74 is rotatably arranged on the hard tube 71, and the guide wheel 74 is adapted to the guide plate 75.

[0039] It should be noted that the bottom end of the bellows 1 73 is fixedly connected to a fan, which is used to blow hot air, so that the hot air is blown toward the charging port 22 through the nozzle 1 72. The bottom of the positioning clamp 5 is fixedly provided with a fixing seat 1, and the fixing seat 1 is fixedly provided with a spring. The end of the spring away from the fixing seat 1 is fixed to the hard tube 1 71.

[0040] It should also be noted that when the fan is started, warm gas is ejected from the exhaust end of the fan. The warm gas is guided by the bellows 73 and the hard tube 71, and finally the warm gas is sprayed into the charging port 22 through the nozzle 72, thereby accelerating the evaporation of moisture in the charging port 22. When the evaporation of moisture in the charging port 22 is completed, the law enforcement instrument body 2 is driven to move vertically downward. During the vertical downward movement of the law enforcement instrument body 2, since the guide plate 75 is inclined, the guide wheel 74 is rollingly connected to the guide plate 75. Under the guidance of the guide plate 75, the nozzle 72 and the bottom of the positioning clamp 5 are horizontally moved to avoid interference caused by the nozzle 72 during the insertion of the charging connector 12 into the charging port 22.

[0041] Refer to the instruction manual Figures 3 to 6Law enforcement officers work in a variety of adverse weather and environments to ensure public safety and social order. For example, in some areas, sandstorms can reduce visibility, affect traffic safety, and also have adverse effects on people's respiratory systems. Law enforcement officers need to ensure the safety of pedestrians and vehicles under such conditions. When law enforcement officers work in such an environment, there will be some particulate impurities in the charging port 22. If only the hard tube 1 71 is used to blow away the particulate impurities in the charging port 22, the impurities in the positioning groove 11 will move disorderly, which may cause the particulate impurities to fall into the charging connector 12. If there are particulate impurities in the charging connector 12, the friction between the charging connector 12 and the charging port 22 will be increased when the charging connector 12 is connected to the charging port 22, shortening the service life of the charging connector 12 and the charging port 22. To solve the above problems, a dust removal mechanism 8 is specifically provided in the positioning groove 11. The dust removal mechanism 8 includes a hard tube 2 81. A nozzle 2 82 is fixedly provided on the hard tube 81 and is arranged toward the charging port 22. The dust removal mechanism 8 also includes a second bellows 83, the top of which is fixedly connected to the bottom of the second rigid tube 81. A second nozzle 82 is slidably mounted on the bottom of the positioning clamp 5. A second guide plate 85 is rotatably mounted on the second rigid tube 81, and a second guide plate 85 is fixedly mounted within the positioning groove 11. A second guide wheel 84 is rotatably mounted on the second rigid tube 81, and the second guide wheel 84 is adapted to fit the second guide plate 85. A second fixing seat is fixedly mounted on the bottom of the positioning clamp 5, and a spring is fixedly mounted on the second fixing seat. The end of the spring, which is away from the second fixing seat, is fixedly mounted to the second rigid tube 81.

[0042] It should be noted that the bottom of the second bellows 83 is fixedly connected to an exhaust fan, which extracts gas and, under the guidance of the second bellows 83 and the second hard tube 81, extracts particulate impurities in the charging port 22 through the second nozzle 82.

[0043] It should also be noted that when the exhaust fan is started, the exhaust end of the exhaust fan extracts gas to form a negative pressure. The negative pressure airflow is guided by the bellows 2 83 and the hard tube 2 81, and finally the negative pressure airflow is connected to the charging port 22 through the nozzle 2 82, thereby extracting the particulate impurities in the charging port 22. When the particulate impurities in the charging port 22 are cleaned, the law enforcement instrument body 2 is driven to move vertically downward. During the vertical downward movement of the law enforcement instrument body 2, since the guide plate 2 85 is tilted, the guide wheel 2 84 is rollingly connected to the guide plate 2 85. Under the guidance of the guide plate 2 85, the nozzle 2 82 and the bottom of the positioning clamp 5 are horizontally moved to avoid interference caused by the nozzle 2 82 during the insertion of the charging connector 12 into the charging port 22.

[0044] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
