Description

Technical Field

[0001] The utility model relates to the technical field of shields, in particular to an intelligent police shield. Background Art

[0002] Folding shields are portable protective equipment designed to provide immediate protection and flexibility to address the limitations of traditional riot shields in terms of portability and maneuverability. Such shields are usually made of lightweight but strong materials, can be quickly deployed for use, and can be folded up when not in use for easy storage and carrying.

[0003] For example, Chinese patent CN117387423A discloses a multi-form, multi-functional foldable shield and a method of using the same. The foldable shield includes two folding units, a folding lock, a hook, a semi-expanding lock, a spring hinge and a rigid frame. Under the action of the spring hinge and a variety of locks, the shield can be quickly unfolded and formed into two different unfolding forms, which can be used as a handheld shield and a shooting shelter respectively.

[0004] However, the existing intelligent folding shield needs to be manually activated, and it is difficult to quickly enter the working state in an emergency, and it is not possible to protect the safety of law enforcement officers and the public in time. Therefore, it is urgent to develop an intelligent police shield to solve the problems in the existing technology. Utility Model Content

[0005] The utility model aims to provide an intelligent police shield, which solves the problem that the existing folding shield has only a single shield function by arranging a control mechanism and a detection mechanism suitable for the folding police shield on the folding police shield.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An intelligent police shield, comprising

[0008] A police shield body, wherein the police shield body is a foldable police shield;

[0009] A control mechanism, the control mechanism is arranged on the shield body, and the control mechanism includes a power supply battery and a controller electrically connected to the power supply battery;

[0010] A detection mechanism, wherein the detection mechanism is electrically connected to the controller, and the power supply battery is electrically connected to the detection mechanism;

[0011] When the detection mechanism detects that the foldable warning shield is unfolded, the detection mechanism outputs a power-on signal, and the controller is powered on; when the detection mechanism detects that the foldable warning shield is folded, the detection mechanism outputs a power-off signal, and the controller is powered off.

[0012] Furthermore, the detection mechanism includes a Hall sensor and a magnet cooperating with the Hall sensor. The Hall sensor and the magnet are installed on the folding warning shield in cooperation with each other. When the folding warning shield is folded or unfolded, the output signal of the output end of the Hall sensor changes.

[0013] Furthermore, when the foldable warning shield is folded, the magnet is close to the Hall sensor; when the foldable warning shield is unfolded, the magnet is far away from the Hall sensor.

[0014] Further, the power supply battery is electrically connected to the controller via a DC-DC converter, and the output end of the Hall sensor is connected to an enable pin of the DC-DC converter;

[0015] When the magnet is away from the Hall sensor, the output terminal of the Hall sensor outputs a high level, and the power supply battery supplies power to the controller through a DC-DC converter;

[0016] When the magnet approaches the Hall sensor, the output terminal of the Hall sensor outputs a low level, the DC-DC converter stops working, and the controller is powered off.

[0017] Furthermore, the control mechanism also includes a Bluetooth module, which is electrically connected to the controller and is powered by the power supply battery.

[0018] Furthermore, the control mechanism also includes an LED, and the LED is electrically connected to the controller.

[0019] Furthermore, the control mechanism also includes a buzzer, which is electrically connected to the controller, and the controller controls the buzzer.

[0020] Furthermore, the power supply battery is electrically connected to the buzzer via a boost chip.

[0021] Furthermore, the control mechanism also includes a charging chip, and the charging chip is electrically connected to the power supply battery.

[0022] Furthermore, the control mechanism also includes an indicator light, and the indicator light is electrically connected to the controller.

[0023] Compared with the prior art, the beneficial effects of the utility model are: a detection mechanism is set to detect whether the folding police shield is in the unfolded state, so as to realize automatic power-on of the controller when the folding police shield is unfolded, eliminating the manual start-up process, so that the smart police shield can quickly enter the working state in an emergency, and timely protect the safety of law enforcement personnel and the public. At the same time, it reduces the need to manually open the equipment, so that law enforcement personnel can focus more on task execution rather than equipment operation.

[0024] Furthermore, by detecting whether the folding warning shield is in a folded state, the controller can be automatically powered off when the folding warning shield is folded, eliminating the need for manual power-off and avoiding the problem of battery exhaustion due to forgetting to power off, which also helps to reduce energy consumption.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] A smart warning shield, such as Figures 1 to 3 Shown, including

[0033] A police shield body, wherein the police shield body is a foldable police shield;

[0034] A control mechanism, the control mechanism is arranged on the shield body, and the control mechanism includes a power supply battery and a controller electrically connected to the power supply battery;

[0035] A detection mechanism, wherein the detection mechanism is electrically connected to the controller, and the power supply battery is electrically connected to the detection mechanism;

[0036] When the detection mechanism detects that the foldable warning shield is unfolded, the detection mechanism outputs a power-on signal, and the controller is powered on; when the detection mechanism detects that the foldable warning shield is folded, the detection mechanism outputs a power-off signal, and the controller is powered off.

[0037] This application sets up a detection mechanism to detect whether the folding police shield is in the unfolded state, so as to realize automatic power-on of the controller when the folding police shield is unfolded, eliminating the manual startup process, so that the smart police shield can quickly enter the working state in an emergency, and timely protect the safety of law enforcement personnel and the public. At the same time, it reduces the need to manually start the equipment, allowing law enforcement personnel to focus more on task execution rather than equipment operation.

[0038] Furthermore, by detecting whether the folding warning shield is in a folded state, the controller can be automatically powered off when the folding warning shield is folded, eliminating the need for manual power-off and avoiding the problem of battery exhaustion due to forgetting to power off, which also helps to reduce energy consumption.

[0039] The detection mechanism includes a Hall sensor and a magnet matched with the Hall sensor. The Hall sensor and the magnet are matched and installed on the folding warning shield. When the folding warning shield is folded or unfolded, the output signal of the Hall sensor changes.

[0040] In this embodiment, when the foldable warning shield is folded, the magnet approaches the Hall sensor, and the Hall sensor outputs a low level, that is, outputs a power-off signal, so that the controller is powered off; when the foldable warning shield is unfolded, the magnet moves away from the Hall sensor, and the Hall sensor outputs a high level, that is, outputs a power-on signal, so that the controller is powered on.

[0041] The present application utilizes a Hall sensor to detect the position of a magnet to determine the unfolded and folded states of the foldable shield with high accuracy.

[0042] In this embodiment, the folding warning shield includes a main body 11 arranged in the middle and shield pieces 12 arranged at both ends. The main body 11 and the shield pieces 12 are rotationally locked and connected. Optionally, the Hall sensor is arranged on the main body 11, and the magnet is cooperatively arranged on the shield piece 12.

[0043] In this embodiment, the controller is a single chip microcomputer U12 (MCU).

[0044] like Figure 2 As shown, the power supply battery is electrically connected to the controller via a DC-DC converter U2, and the output end of the Hall sensor or its chip U3 is connected to the enable (EN) pin of the DC-DC converter U2. In this embodiment, the power supply battery is connected to the P1 interface.

[0045] When the magnet is away from the Hall sensor, the output terminal of the Hall sensor outputs a high level, and the power supply battery supplies power to the controller through a DC-DC converter;

[0046] When the magnet approaches the Hall sensor, the output terminal of the Hall sensor outputs a low level, the DC-DC converter stops working, and the controller is powered off.

[0047] As an optional implementation, the power supply battery can also be connected to the controller via a transistor or other means. If a transistor is used for connection, the output end of the Hall sensor is connected to the base of the transistor. When the Hall sensor outputs a low level, the transistor is in a cut-off state and the controller is powered off. When the Hall sensor outputs a high level, the transistor is in a saturated state and the controller is powered on.

[0048] As an optional implementation, the detection mechanism may also be an inductive sensor, so as to determine the unfolding and folding states of the folding shield by detecting the distance between the folding shield and the detection end of the inductive sensor through the inductive sensor.

[0049] The control mechanism also includes a buzzer, which is electrically connected to the controller, and the controller controls the buzzer to sound an alarm. The power supply battery is electrically connected to the buzzer through a boost chip to power the buzzer that requires a higher voltage. Figure 3 The power supply battery is electrically connected to the buzzer through the boost chip U1.

[0050] The control mechanism further comprises an LED, which is electrically connected to the controller, and the controller controls the LED to flash as an alarm.

[0051] The control mechanism also includes a Bluetooth module U4, which is electrically connected to the controller and communicates with the MCU through a serial port. When in use, the smart shield can be connected to the mobile phone Bluetooth by scanning the QR code on the smart shield. After the connection is completed, the current status of the smart shield can be seen, such as battery power, shield number and other information. In this embodiment, the Bluetooth module U4 is also connected to the antenna T5.

[0052] The control mechanism also includes a charging chip U11, which is electrically connected to the power supply battery. The charging chip U11 is equipped with a type-c charging interface. When the battery is out of power, an adapter or other USB interface can be used to charge the battery.

[0053] The control mechanism further includes an indicator light for displaying the charging status of the power supply battery. The indicator light is electrically connected to the controller, and the controller controls the indicator light to display the charging status of the power supply battery. Figure 3 Middle port P5 is electrically connected.

[0054] When in use, open the folding shield, power on the controller, and start communicating with the Bluetooth module. After the Bluetooth module is successfully turned on, the MCU receives the status that Bluetooth is successfully turned on and starts the next step.

[0055] Then, the LED and buzzer are turned on, or the LED and buzzer are configured and started separately according to customer needs. For example, the LED can be turned on first, or the buzzer can be turned on first.

[0056] The smart police shield is connected to the mobile phone via a Bluetooth module. At this time, on-site positioning can be carried out through the mobile phone. When the police shield is turned on and support is needed, rapid support and response can be provided based on the mobile phone positioning.

[0057] The utility model provides an intelligent warning shield with simple structure, convenient use and high reliability.

[0058] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
