[0023] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are presented in order to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0024] See Figures 1 to 2 , the first embodiment of the present utility model discloses a safety alarm charging management device, including a heat-resistant protection box, a power switch and an electrical parameter monitoring device arranged outside the heat-resistant protection box, a charging unit, a charging protection unit and a fire detection device arranged inside the heat-resistant protection box, and the power switch, the electrical parameter monitoring device, the charging unit and the charging protection unit are electrically connected.

[0025] The charging unit is electrically connected to the device to be charged and is used to charge the device to be charged. The charging unit can be a PDU (Power Distribution Unit). A PDU, which is also known as the power distribution socket for cabinets that we often mention, is a product designed to provide power distribution for electrical equipment installed in cabinets. It has multiple series of specifications with different functions, installation methods, and different combinations of socket positions, and can provide suitable rack-mounted power distribution solutions for different power environments. The application of the PDU can make the power distribution in the cabinet more neat, reliable, safe, professional, and beautiful, and make the maintenance of the power supply in the cabinet more convenient and reliable. The industrial PDU socket board can be adapted to the connection of various devices that need to be charged, and is durable and reliable.

[0026] Further, in order to avoid the accumulation of heat when charging the device to be charged, in the safety alarm charging management device disclosed in this embodiment, the box body of the heat-resistant protection box and the cabinet door are distributed with heat dissipation holes. A plurality of heat dissipation holes together form a hollow heat dissipation area, which is distributed in each part of the heat-resistant protection box. Among them, in some preferred solutions, a plurality of heat dissipation areas are arranged at symmetrical positions on the box body to facilitate the convective heat transfer of internal and external air.

[0027] In some other embodiments, the safety alarm charging management device further includes a heat exchanger, and the heat dissipation area is correspondingly arranged with the heat exchanger to facilitate heat exchange inside and outside the box, avoid the accumulation of heat inside the heat-resistant protection box, and reduce the possibility of fire. The heat exchanger can be a fan and / or heat sink fins.

[0028] Further, in order to assist the user in managing the device to be charged, the safety alarm charging management device disclosed in this embodiment further includes a first indicator light and a second indicator light. Both the first indicator light and the second indicator light can be fluorescent tubes or LEDs. Among them, when the power switch is turned on, if the cabinet door is closed, the first indicator light is turned on; if the cabinet door is not closed, the second indicator light is turned on. In order to better prompt the user, the first indicator light and the second indicator light can also be indicator lights of different colors. For example, the first indicator light is a red light, while the second indicator light is a white light. Or, when the second indicator light is turned on, its working mode is to flash the light to achieve the purpose of reminding the user. When the power switch of the safety alarm charging management device is turned on, at least one of the first indicator light and the second indicator light will be on, which can have the beneficial effect of providing lighting for the user.

[0029] In some other embodiments, the safety alarm charging management device further includes a plurality of third indicator lights. These third indicator lights are arranged on the charging unit or on the inner side of the box body, and these third indicator lights are turned on when the device to be charged is placed at the corresponding position of the charging unit, and are used to indicate the charging status of the device to be charged at the corresponding position of the charging unit.

[0030] Further, in the safety alarm charging management device disclosed in this embodiment, a heat-resistant partition board is provided inside the heat-resistant protection box to divide the interior of the heat-resistant protection box into different internal areas. Among them, each internal area is provided with one of the charging units. The heat-resistant partition board can separate the heat generated by each charging unit and its connected device to be charged, preventing the heat of all charging units from gathering together. Also, in the event of a fire accident in a certain charging unit, the fire can be confined to the location of that charging unit, avoiding the spread of the fire and reducing the losses caused by accidents.

[0031] Further, in the safety alarm charging management device disclosed in this embodiment, a number of support columns are also provided inside the heat-resistant protection box. These support columns are longitudinally arranged inside the box body to provide corresponding support for the heat-resistant partition board. Compared with the scheme where the heat-resistant partition board is directly connected to the box body, the gap between the support rods and the box body is more conducive to ventilation and heat dissipation inside the box body.

[0032] Further, in the safety alarm charging management device disclosed in this embodiment, the fire detection device includes a smoke alarm. The fire detection device can also be a temperature sensor or an infrared sensor. The fire detection device also includes a wireless transmission module, which can remotely transmit the alarm information to communication devices such as the user's mobile terminal or the console, delivering the safety alarm to the user in a timely and rapid manner.

[0033] Further, in the safety alarm charging management device disclosed in this embodiment, the heat-resistant protection box includes a cabinet door at least partially made of transparent heat-resistant material. The transparent part can be a transparent window provided on the cabinet door, and the number of such transparent windows can be 1, or multiple corresponding to the heat-resistant partition board. Users can observe the real-time situation inside the safety alarm charging management device through the transparent part of the cabinet door, which is also convenient for grasping the charging level of the devices to be charged.

[0034] Further, in the safety alarm charging management device disclosed in this embodiment, the electrical parameter monitoring device can be a digital display monitor. The parameters monitored by the electrical parameter monitoring device include current, voltage, electric energy, and temperature. In order to achieve automatic monitoring, the electrical parameter monitoring device also correspondingly sets current ranges, voltage ranges, electric energy ranges, and temperature ranges. When the current, voltage, electric energy, and temperature approach the end values of their corresponding ranges, the electrical parameter monitoring device will further analyze the corresponding parameters. In the electrical parameter monitoring device, the current, voltage, electric energy, and temperature status of the bus can be displayed, or the current, voltage, electric energy, and temperature status of each device to be charged, or the electrical parameters of each group of charging units can be specifically displayed.

[0035] Further, in the safety alarm charging management device disclosed in this embodiment, when the parameters monitored by the electrical parameter monitoring device reach a preset threshold, an alarm signal is emitted. For example, when it is detected that the device to be charged has a voltage loss or undervoltage, the electrical parameter monitoring device emits an alarm signal. In some other embodiments, if the change rate of a certain parameter exceeds the preset rate, it indicates that there is an abnormality in the entire safety alarm charging management device, and the electrical parameter monitoring device will also emit an alarm signal.

[0036] Further, in the safety alarm charging management device disclosed in this embodiment, the power switch includes a low-voltage circuit breaker with a timing function. Adjusting the timing of the low-voltage circuit breaker to match the full charge duration of the device to be charged can avoid overcharging of the device to be charged. Or, adjusting the timing of the low-voltage circuit breaker to a preset predetermined time can cause the safety alarm charging management device to automatically cut off the power after reaching the predetermined time, realizing that the safety alarm charging management device can only be powered on with user operation, reducing the potential hazard of fire accidents.

[0037] Further, the charging protection unit is used to protect the charging device. In the safety alarm charging management device disclosed in this embodiment, the charging protection unit includes an air switch. The charging protection unit provides short-circuit protection and over-current protection for the entire safety alarm charging management device, realizing automatic safety protection when the user is not on site. The charging protection unit can also be a fuse.

[0038] Further, in the safety alarm charging management device disclosed in this embodiment, it also includes a connection to a display instrument to realize the working voltage and current of the current device and monitor the internal temperature information, providing information reading and alarm for the user. Using this safety alarm charging management device, it can only be powered on with user operation, automatically cut off the power after reaching the predetermined time, and avoid overcharging; the user judges the safety alarm charging management device through the indicator light, and the indicator light can also provide a lighting function at the same time.

[0039] The safety alarm charging management device disclosed in this embodiment only requires the user to operate the power switch to power on and off, and further set the automatic power-off duration, and the rest of the functions can be realized by the device itself, combining high efficiency, centralization and safety.

[0040] See Figure 3 , the second embodiment of the present utility model discloses a specific safety alarm charging management device, including a first charging unit CZ1, a second charging unit CA2, and a third charging unit CZ3 connected in parallel between the neutral line N and the live line L, and the other ends of the first charging unit CZ1, the second charging unit CA2, and the third charging unit CZ3 are commonly connected to the ground wire PE.

Specifically, the part of the limit switch SM1 connected to the white lamp AH1 is a normally closed switch, and the part of the limit switch SM1 connected to the red lamp AH2 is a normally open switch, and the normally closed switch and the normally open switch act in linkage.

[0043] The safety alarm charging management device is also provided with a smoke alarm BJ1, which is independently powered and detects the smoke status in the box at all times.
