Description

Technical Field

[0001] The utility model relates to the technical field of product testing, in particular to an automatic alarm protection device. Background Art

[0002] During the development stage of some new products, such as computers, power adapters, routers, etc., in order to test the heat dissipation performance of the product, a quilt covering test is often performed to verify whether the heat dissipation design of the product is reasonable, so as to ensure that it can work stably in harsh environments.

[0003] Take the adapter as an example. During the quilt covering test, the adapter is required to be tightly wrapped with a quilt for four hours. During the test, no safety issues, such as molten shell fire, should occur. Therefore, when the equipment is conducting the quilt covering test, the whole process needs to be carried out under the supervision of the tester. However, in the current adapter quilt covering test, when the adapter surface is abnormally high in temperature and abnormal conditions such as molten shell fire occur, it cannot be quickly discovered by the naked eye. If the tester fails to discover it in time, problems such as test safety will arise. Utility Model Content

[0037] In this embodiment, an automatic alarm protection device is provided, which can be used for the adapter quilt covering test. Figure 1 1 is a schematic diagram of the structure of an automatic alarm protection device according to an embodiment of the utility model, including a temperature sensing unit, an alarm unit, a power supply module and a control unit, as follows.

[0038] The temperature sensing unit is used to detect the current temperature of the adapter to be tested, where the adapter to be tested can be various types of power plugs, such as mobile phone chargers, computer chargers, etc. When conducting a quilt covering test, the adapter to be tested can be placed in an environment that simulates being covered, such as a fully enclosed or semi-enclosed housing, and then the adapter to be tested is connected to the power supply for normal use to test the current temperature of the adapter surface when the adapter to be tested is covered. The quilt covering test refers to the CQC1626-2020 certification specification.

[0039] The alarm unit is used to issue an alarm when the current temperature exceeds a first preset temperature. The first preset temperature may be 30°C, 35°C, etc. The alarm unit may be a buzzer, etc. The triggering principle diagram of the buzzer may refer to Figure 2 shown.

[0040] The power supply module is electrically connected to the external power supply and is used to provide power for the adapter to be tested, wherein the external power supply can be a 220V standard power supply. In this embodiment, the adapter to be tested can be first inserted into a power socket with a protection function, and then the power socket is provided with a standard power supply to realize power supply for the adapter to be tested.

[0041] Reference Figure 3 As shown, the control unit is electrically connected to the temperature sensing unit for receiving the current temperature; the control unit is also electrically connected to the alarm unit for controlling the alarm unit to issue an alarm prompt when the current temperature exceeds the first preset temperature; the control unit is also electrically connected to the power supply module for disconnecting the power supply to the adapter to be tested through a power socket with a protection function when the current temperature exceeds a second preset temperature, such as 40°C.

[0042] The utility model proposes an automatic alarm protection device for abnormal situations in the adapter quilt covering test. When the surface temperature of the adapter is detected to exceed the preset temperature, an alarm prompt is automatically issued to remind the tester to check in time. When the temperature is higher or a fire occurs, the power input of the adapter can be automatically cut off. In this way, when performing the adapter quilt covering test, not only can manual dependence be effectively reduced, but also problems such as test safety due to the negligence of the tester can be effectively avoided.

[0043] It should be noted that the embodiments of the present utility model mainly introduce the hardware structure of the automatic alarm protection device. The present utility model is also intended to protect the structure and components of the automatic alarm protection device. As for the control logic and other method contents therein, the existing logic can be fully adopted.

[0044] Reference Figure 1 As shown, in some optional embodiments, the automatic alarm protection device further includes:

[0045] The emergency button is electrically connected to the control unit. When the emergency button is pressed, the power supply module disconnects the power supply to the adapter to be tested. In an emergency, the tester can actively press the emergency button. When the control unit detects that the emergency button is pressed, the controller controls the power supply module to disconnect the power supply to the adapter to be tested. This ensures that the tester can respond to emergencies in a timely manner, effectively improves the safety of the entire test process, and reduces potential risks.

[0046] In some optional embodiments, the power supply module includes:

[0047] The relay unit is electrically connected to the control unit, wherein the relay unit can be integrated with the power socket. When the current temperature exceeds the second preset temperature, the control unit controls the relay unit to disconnect. Figure 4 shown.

[0048] The power socket is electrically connected to the relay unit and the external power supply respectively. When the plug of the adapter to be tested is inserted into the socket of the power socket, power supply is realized.

[0049] In this embodiment, a power supply module with a relay unit is used. Through the cooperation of the control unit and the relay unit, when the current temperature exceeds the second preset temperature, the relay can be controlled to be disconnected to achieve automatic power-off of the adapter to be tested, thereby preventing safety accidents such as equipment damage or fire caused by overheating of the adapter to be tested, thereby improving safety.

[0050] In some optional embodiments, the power supply module includes:

[0051] The isolated power supply unit is electrically connected to the external power supply and the control unit respectively, and is used to convert the external power supply into an adaptive power supply, and use the adaptive power supply to power the control unit, thereby realizing power supply for the temperature sensing unit, the display unit, the alarm unit and the emergency button.

[0052] In this embodiment, the isolated power supply unit can effectively isolate the interference and fluctuation of the external power supply, protect the internal control unit and its related components, and improve the safety and stability of the test.

[0053] In some optional embodiments, the automatic alarm protection device further comprises:

[0054] The shell is used to place the adapter to be tested, which can effectively simulate the situation that the adapter is covered, and can also ensure the safety of the surrounding environment and testers when the adapter to be tested has abnormal conditions.

[0055] In some optional implementations, the temperature sensing unit, the alarm unit, the power supply module, and the control unit are arranged on the housing, so that the integrated design of the device can be realized, which can adapt to different test environments and requirements and improve the flexibility of selecting the test site.

[0056] In some optional embodiments, the automatic alarm protection device further comprises:

[0057] The display unit is connected to the control unit and is arranged on the housing for displaying the current temperature.

[0058] In some optional embodiments, the temperature sensing unit, alarm unit, control unit, and display unit are arranged on the top of the shell, which not only facilitates timely viewing or control by test personnel, but also effectively avoids damage to components such as the temperature sensing unit, alarm unit, control unit, and display unit due to overtemperature or fire of the adapter, thereby ensuring the long-term reliability of the device.

[0059] In some optional implementations, the temperature sensing unit is an infrared thermal imaging sensor, so that the current temperature of the adapter can be detected without contacting the surface of the adapter, which can effectively avoid damage to the temperature sensing unit.

[0060] In some optional embodiments, the display unit is a digital display screen, which enables the tester to view the current temperature information clearly and intuitively, thereby improving the efficiency of supervision.

[0061] Since the adapter quilt covering test requires full supervision by the tester and needs to last for about four hours, it is difficult for the tester to supervise the whole process and check whether there is any safety situation when wrapping the adapter. The automatic alarm protection device provided by the utility model, based on the current test conditions, adds auxiliary devices such as temperature sensors, buzzers and relay power sockets. After an abnormal situation occurs, it can promptly issue an alarm prompt to remind the tester to check the test situation in time, avoiding the occurrence of safety problems due to the negligence of the tester and the failure to check the test situation in time. It is also possible to disconnect the adapter input power in time when an extreme fire phenomenon occurs to avoid safety hazards in extreme situations. It also supports manual disconnection of the input switch in an emergency, and has a certain degree of testing flexibility.

[0062] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
