Description

Technical Field

[0001] The present invention relates to the technical field of charging devices, and more specifically, 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. In order to improve law enforcement efficiency, protect public safety, and ensure the transparency and legality of the law enforcement process, law enforcement personnel need to carry law enforcement equipment in their daily law enforcement work. In order to record the situation at the law enforcement scene in real time, the law enforcement equipment has a camera that meets the video function. In order to enhance the clarity of the video in low-light or no-light environments, the camera on the law enforcement equipment uses a camera with thermal imaging function.

[0003] For the sake of efficiency, compliance and fairness, and to ensure the comprehensiveness and non-tamperability of information during law enforcement, 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 picture taken 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 was connected to the reading device via the USB interface, the power management system of the law enforcement equipment failed to effectively strike the correct balance between charging and powering the reading device. When the thermal imaging camera was turned on and connected to the reading device via the USB interface, it occupied the power resources that should have been used for charging, resulting in the law enforcement equipment being unable to charge effectively even if the socket charger was plugged in. Summary of the invention

[0005] The automatic shutdown charging device for law enforcement equipment based on NFC tags provided by the present invention aims to solve the problem that, in the existing automatic shutdown charging device for law enforcement equipment, when the thermal imaging camera is connected to the reading device via the 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.

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here 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. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] 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 supporting base 1, a positioning groove 11 is provided on the supporting 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 supporting base 1.

[0028] It should be noted that the automatic shutdown charging device is used to charge the law enforcement equipment with the NFC tag, which includes a law enforcement instrument body 2, a USB thermal imaging camera 21 is arranged in the law enforcement instrument body 2, a charging port 22 is arranged on the law enforcement instrument body 2, and the charging connector 12 is adapted to the charging port 22. An NFC antenna 3 is arranged in the law enforcement instrument body 2, and the NFC antenna 3 is used to read the information of the NFC tag 4.

[0029] It should be noted that the instruction stored in the NFC tag 4 is the instruction to shut down the body 2 of the law enforcement instrument. The information stored in the NFC tag 4 is usually a URL or other types of NDEF messages. Programming can be completed through a special NFC programming tool or application. These tools allow you to write data to a blank writable NFC tag. The body 2 of the law enforcement instrument has an NFC tag 4. The NFC tag 4 can identify the information in the body 2 of the law enforcement instrument and make corresponding instructions. The cooperation between the NFC tag 4 and the body 2 of the law enforcement instrument is a mature existing technology and will not be described in detail here.

[0030] The specific implementation scenario is: place the body 2 of the law enforcement instrument in the positioning slot 11, insert the charging connector 12 into the charging port 22, and the NFC antenna 3 obtains the command edited in the NFC tag 4 to complete the shutdown of the body 2 of the law enforcement instrument. At this time, the body 2 of the law enforcement instrument can be charged by inserting the charging connector 12 into the charging port 22. It can also provide users with a simple and efficient method to manage and optimize the power usage of law enforcement equipment without changing the existing hardware architecture, especially when high-power consumption peripherals are involved.

[0031] 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 arranged in the positioning groove 11, and the two positioning clamps 5 are fixedly arranged by the same connecting rod 51, and the positioning clamp 5 is used to clamp and position the law enforcement instrument body 2. A linear drive mechanism 6 is arranged in the positioning groove 11, and the linear drive mechanism 6 includes a rotating driver 61, and the rotating driver 61 is fixedly arranged in the positioning groove 11. A screw 62 is fixedly arranged on the output shaft of the rotating driver 61, and a connecting seat is fixedly arranged on the positioning clamp 5, and the screw 62 is threadedly connected to the connecting seat. A guide seat is fixedly arranged in the positioning groove 11, and a slide groove is opened on the guide seat. An auxiliary seat is fixedly arranged on the positioning clamp 5, and the auxiliary seat is slidably arranged in the slide groove. A guide shaft is fixedly arranged on the inner wall of the slide groove, and the auxiliary seat and the guide shaft are slidably arranged.

[0032] It should be noted that the rotary driver 61 is configured as a motor, and the output shaft of the motor is fixedly arranged with the screw rod 62. The outer fixed sleeve of the guide shaft is provided with an 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 clamp". As a mature prior art, it will not be elaborated here. A flexible support cotton is fixedly arranged 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.

[0033] 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 clamps 5 is used to clamp the law enforcement instrument body 2 under the action of elastic force, and then the rotating driver 61 is started, and the rotation of the output shaft of the rotating driver 61 drives the screw rod 62 to rotate, and 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.

[0034] 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. 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, specifically, a dehumidification mechanism 7 is provided in the positioning groove 11, and the dehumidification mechanism 7 includes a hard tube 71, and a nozzle 72 is fixedly provided on the hard tube 71, and 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.

[0035] It should be noted that the bottom end of the bellows 1 73 is fixedly connected to a fan, which is used to blow out hot air, so that the hot air is blown toward the charging port 22 through the nozzle 1 72. A fixing seat 1 is fixedly arranged at the bottom of the positioning clamp 5, and a spring is fixedly arranged on the fixing seat 1, and one end of the spring away from the fixing seat 1 is fixedly arranged with the hard tube 1 71.

[0036] It should also be noted that when the fan is started, warm gas is ejected from the exhaust end of the fan, and 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 water in the charging port 22. When the evaporation of water 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, thereby avoiding interference caused by the nozzle 72 during the insertion of the charging connector 12 into the charging port 22.

[0037] Refer to the instruction manual Figures 3 to 6, law enforcement officers are on duty in a variety of severe 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 system. Law enforcement officers need to ensure the safety of pedestrians and vehicles under such conditions. Law enforcement officers are on duty 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 aggravated 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. In order to solve the above problems, specifically, a dust removal mechanism 8 is provided in the positioning groove 11, and the dust removal mechanism 8 includes a hard tube 2 81, and a nozzle 2 82 is fixedly provided on the hard tube 21, and the nozzle 2 82 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 hard tube 81, a second nozzle 82 is slidably arranged with the bottom of the positioning clamp 5, a second guide plate 85 is rotatably arranged on the second hard tube 81, a second guide plate 85 is fixedly arranged in the positioning groove 11, and a second guide wheel 84 is rotatably arranged on the second hard tube 81, and the second guide wheel 84 is adapted to the second guide plate 85. A second fixing seat is fixedly arranged at the bottom of the positioning clamp 5, and a spring is fixedly arranged on the second fixing seat, and one end of the spring away from the second fixing seat is fixedly arranged with the second hard tube 81.

[0038] It should be noted that the bottom of the second bellows 83 is fixedly connected to an exhaust fan, which extracts gas. Under the guidance of the second bellows 83 and the second hard tube 81, particulate impurities in the charging port 22 are extracted through the second nozzle 82.

[0039] It should also be noted that when the exhaust fan is started, the exhaust end of the exhaust fan draws gas to form a negative pressure, and 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 inclined, the guide wheel 2 84 is rollingly connected to the guide plate 2 85, and under the guidance of the guide plate 2 85, the nozzle 2 82 and the bottom of the positioning clamp 5 are horizontally moved, thereby avoiding interference caused by the nozzle 2 82 during the insertion of the charging connector 12 into the charging port 22.

[0040] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
