[0057] Cabinet inspection and maintenance are crucial for ensuring the proper operation of equipment and extending its lifespan. Regular inspections and maintenance of cabinets typically require inspections of cables, equipment, fans, and heat dissipation within the cabinets to confirm the status of these devices and troubleshoot any potential faults. Furthermore, if a fault occurs during equipment operation, the cabinets must also be inspected to eliminate the problem. Because the system has high environmental requirements during operation, cabinets are often placed in specific environments. For example, IT equipment in liquid-cooled data centers is typically placed in TANK cabinets. These cabinets are typically located in dedicated computer rooms, and the environment is often dim during maintenance, requiring the cabinet's lighting system to be turned on for inspection.

[0058] Current cabinet lighting systems typically utilize the cabinet's own power supply, splitting a circuit from the cabinet's own power supply for lighting. This approach eliminates the need for additional power equipment and is relatively convenient. However, when a system failure occurs, particularly a power outage, the cabinet lighting can also experience issues, significantly complicating cabinet maintenance.

[0059] The inventors of this application have discovered that in order to solve the problem of system power outages, a backup power supply can be installed inside the cabinet. However, on the one hand, the backup power supply will take up space in the cabinet. On the other hand, as the usage time increases, the service life of the backup power supply will also bring new operation and maintenance problems.

[0060] In view of this, the applicant has proposed a cabinet that combines the existing system power supply unit and the energy conversion unit by arranging an energy conversion unit and a power supply merging unit inside the cabinet. During routine maintenance, when the system power supply unit is operating normally, the power supply merging unit controls the system power supply unit to provide lighting power for the cabinet or other loads. On the other hand, when the upper cover of the cabinet is opened or closed, the energy conversion unit generates electrical energy and stores the generated electrical energy. When the system power supply unit loses power, the power supply merging unit automatically switches the power supply to the load unit to be supplied by the energy conversion unit. The energy conversion unit uses the normally stored electrical energy to provide lighting power for the cabinet or other loads. In this way, the existing system power supply is utilized to power the cabinet, and the kinetic energy generated by opening or closing the upper cover is converted into electrical energy by the energy conversion unit and stored as a backup power source. This greatly increases the service life of the backup power source and saves energy consumption during the use of the cabinet.

[0061] The cabinet proposed in the embodiment of the present application can be applied to various scenarios, such as: air-cooled heat dissipation system, liquid-cooled heat dissipation system or server cabinet and other electronic systems, which are not limited here.

[0062] Specifically, such as Figure 1 and Figure 2The figure shows a schematic diagram of the structure of the cabinet 100 proposed in an embodiment of the present application. The cabinet 100 includes an upper cover 10 and a box body 20; an energy conversion unit 30, a system power supply unit 40, a power supply merging unit 50, a switch unit 60 and a load unit 70 are arranged in the box body 20; the energy conversion unit 30 is arranged at the connection between the box body 20 and the upper cover 10, and when the upper cover 10 rotates relative to the box body 20, the energy conversion unit 30 is driven to generate electric energy; the output end of the energy conversion unit 30 is electrically connected to the energy conversion unit power input end Vin2 of the power supply merging unit 50, for outputting power to the power supply merging unit 50; the system power supply unit 40 is connected to the power supply merging unit 50, and ... The output end of 40 is electrically connected to the system power input end Vin1 of the power supply merging unit 50, and is used to output power to the power supply merging unit 50; the power supply merging unit 50 receives the power output by the energy conversion unit 30 and the system power supply unit 40, and is electrically connected to the switch unit 60 through the power output end Vout of the power supply merging unit, and outputs the merged power to the switch unit 60; one end of the switch unit 60 is electrically connected to the power output end Vout of the power supply merging unit, and the other end is electrically connected to the load unit 70, and is used to control the merged power input to the load unit 70.

[0063] like Figure 1 and Figure 2 As shown, the cabinet 100 includes a box body 20 and an upper cover 10. The cabinet can be placed in an air-cooled environment or a liquid-cooled environment. Corresponding to different heat dissipation environments, the setting method between the upper cover 10 and the box body 20 can be adaptively adjusted, which is not limited here.

[0064] The box 20 is used to accommodate electronic equipment, including but not limited to servers, switches, system power supplies, etc. The box 20 is usually a rectangular or cube structure, and can also be cylindrical or other shapes, as long as it can meet the needs of accommodating system equipment; one side of the upper cover 10 is rotatably connected to the opening edge of the box 20 by a connecting shaft or hinge, and the upper cover 10 can be supported by a support rod to be in an open state to facilitate maintenance of the electronic equipment in the box 20. The shape of the upper cover 10 is adapted to the opening shape of the box 20 and is not limited here.

[0065] In order to accommodate electronic devices, the side walls of the box 20 may have a certain thickness, or a certain accommodation space may be provided on the side walls for accommodating corresponding electronic devices, so as to improve the integration of the box 20 .

[0066] like Figure 1 and Figure 2As shown, the energy conversion unit 30 is arranged at the connection between the box body 20 and the upper cover 10. Figure 1 This is a module diagram of the energy conversion unit 30 on the box 20. Figure 2 This is a structural diagram of the energy conversion unit 30 on the housing 20. The energy conversion unit 30 includes a mechanical structure part and a circuit part. The mechanical structure part of the energy conversion unit 30 is arranged on the housing 20 at a position opposite to the upper cover 10, and cooperates with the upper cover 10 so that when the upper cover 10 rotates relative to the housing 20, that is, during the process of opening or closing, it can drive the mechanical structure part to produce linkage, thereby converting the kinetic energy of the upper cover 10 into electrical energy. The circuit part is used to transmit and store the electrical energy generated by the mechanical structure part, and output the electrical energy generated by it to the power supply merging unit 50. The mechanical structure part and the circuit part can be set in an integrated manner, or they can be separated by being connected by wires, which is not limited in the embodiments of the present application.

[0067] The system power supply unit 40 can be a power supply provided by the electronic device contained within the enclosure, or it can be a power supply specifically provided within the cabinet. To reduce the space occupied within the cabinet, the system power supply unit 40 is preferably a power interface branched from the power module provided by the electronic device. In this way, the cabinet's lighting system can share the power module with the electronic device, reducing the space occupied within the cabinet. The output end of the system power supply unit 40 is electrically connected to the system power input end Vin1 of the power supply merging unit 50.

[0068] Continue to refer Figure 1 and Figure 2 The power supply confluence unit 50 is usually arranged on a circuit board, and the circuit board is fixed in the box body 20. Figure 1 This is a module diagram of the power supply converging unit 50 on the box 20. Figure 2 This is a structural diagram of the power supply converging unit 50 on the housing 20. The power supply converging unit 50 includes a system power input terminal Vin1, an energy conversion unit power input terminal Vin2, and a power supply converging unit power output terminal Vout. The system power input terminal Vin1 is used to electrically connect to the output terminal of the system power supply unit 40 and receive the power signal output by the system power supply unit 40; the energy conversion unit power input terminal Vin2 is used to electrically connect to the output terminal of the energy conversion unit 30 and receive the power signal output by the energy conversion unit 30; the power supply converging unit power output terminal Vout is electrically connected to the switch unit 60 and is used to output the power after the power supply converging unit 50 performs the converging process.

[0069] The power supply confluence unit 50 selects the power signal output by the system power supply unit 40 and the power signal output by the energy conversion unit 30. When the system power supply unit 40 has power output, the power supply confluence unit 50 prioritizes the system power supply unit 40 for external power supply. At this time, the electric energy generated by the energy conversion unit 30 will be stored as a backup power supply; when the system power supply unit 40 loses power, the power supply confluence unit 50 will select the energy conversion unit 30 for external power supply. At this time, the energy conversion unit 30 supplies power to the outside through the stored electric energy.

[0070] The switch unit 60 is mainly used to control the load unit 70. One end of the switch unit 60 is electrically connected to the power output end VOUT of the power supply merging unit. Figure 1 and Figure 2 As shown, the switch unit 60 is typically located at the opening of the cabinet 20 for easy operation. In actual use, the lighting system in the cabinet only needs to be turned on when the upper cover 10 is opened to repair the electronic equipment in the cabinet 20. When the upper cover 10 is closed, the lighting system does not need to be powered to save power. Therefore, the embodiment of the present application saves energy and reduces energy consumption of the cabinet by providing the switch unit 60.

[0071] In the embodiment of the present application, the load unit 70 may be a lighting system, or a sterilization and disinfection system, a fan, or other components that require power consumption, which is not limited here.

[0072] In summary, the cabinet proposed in the embodiment of the present application provides power to the load unit via the system power supply unit 40 and the energy conversion unit 30. When the system power supply unit 40 fails, the electrical energy stored in the energy conversion unit 30 can be used to power the cabinet's load unit 70, facilitating maintenance of the system equipment within the cabinet. Furthermore, the energy conversion unit 30 acts as a backup power source, storing the electrical energy generated by the movement of the upper cover 10 when the system power supply unit 40 is functioning normally. Compared to the traditional method of using batteries as a backup power source, the service life of the energy conversion unit 30 is greatly improved, saving energy while also reducing the cabinet's operation and maintenance costs.

[0073] Further, such as Figure 2 and Figure 3As shown, in some embodiments, in order to improve the efficiency of the energy conversion unit 30 in converting the kinetic energy generated by the upper cover 10 into electrical energy, and at the same time, to reduce the impact of the energy conversion unit 30 on opening or closing the upper cover 10, an embodiment of the present application proposes an energy conversion unit 30, which includes a telescopic part 301, an elastic part 302 and a generator 306; one end of the telescopic part 301 abuts the upper cover 10, and the other end abuts the elastic part 302. When the upper cover 10 is closed or opened, the telescopic part 301 telescopes with the upper cover 10 under the action of the elastic part 302; a rack plate 303 is fixedly provided on one side of the telescopic part 301, and the rack plate 303 is transmission-connected to the generator 306 through a gear 304; when the telescopic part 301 telescopes with the upper cover 10, the rack plate 303 drives the generator 306 to rotate through the gear 304, and the generator 306 generates electrical energy.

[0074] The energy conversion unit 30 can be an integral component, packaged as a whole, or it can be dispersed on the housing 20. When it is packaged as an integral component, the energy conversion unit 30 can include a shell, and the telescopic portion 301, the elastic portion 302, and the generator 306 are disposed within the shell, and are disposed on the housing 20 at the connection with the upper cover 10 through the shell. When the various components of the energy conversion unit 30 are dispersed on the housing 20, the telescopic portion 301, the elastic portion 302, and the generator 306 can be directly fixed to the housing 20 using the housing 20 as a support frame. In this embodiment, the telescopic portion 301, the elastic portion 302, and the generator 306 are disposed within the shell as an example for description.

[0075] The telescopic portion 301 is movably disposed within the housing. The telescopic portion 301 can telescope along a specific path. A track can be provided within the housing to enable the telescopic portion 301 to telescope along the track. During the telescopic movement, one end of the telescopic portion 301 extends out of the housing and abuts against the upper cover 10, while the other end abuts against one end of the elastic portion 302. The other end of the elastic portion 302 abuts against the bottom wall of the housing, providing elastic support for the telescopic portion 301. The elastic portion 302 can be fixed to the bottom wall of the housing. The elastic portion 302 can be a spring or other elastic component.

[0076] A rack plate 303 with teeth is fixedly mounted on one side of the telescopic portion 301. Opposite the rack plate 303, a gear 304 is mounted and rotatably mounted within the housing via a connecting shaft. The rack plate 303 can extend and retract along with the telescopic portion 301. The teeth on the gear 304 mesh with those on the rack plate 303, driving the gear 304 to rotate as the rack plate 303 retracts and retracts.

[0077] Gear 304 is also in driving connection with generator 306, a device that converts mechanical energy into electrical energy. Generator 306 operates based on Faraday's law of electromagnetic induction, which states that when a conductor moves in a magnetic field, an electromotive force is generated in the conductor. Generator 306 typically uses a rotor (a rotating component with a coil) to rotate in a magnetic field to generate current. Gear 304 is in driving connection with the rotor of generator 306. When gear 304 rotates, it drives the rotor of generator 306 to rotate, thereby generating electrical energy.

[0078] When the upper cover 10 is closed, it squeezes the telescopic portion 301, which in turn squeezes the elastic portion 302, causing the elastic portion 302 to accumulate force. The movement of the telescopic portion 301 drives the rack plate 303, which in turn rotates the gear 304. The gear 304 further rotates the rotor of the generator 306, causing the generator 306 to generate electricity.

[0079] When the upper cover 10 is opened, the elastic portion 302 releases its elasticity, pushing the telescopic portion 301 to move in the direction of opening the upper cover 10. During the movement, the telescopic portion 301 drives the rack plate 303 to move, and drives the rotor of the generator 306 to rotate through the gear 304, so that the generator 306 can also generate electrical energy.

[0080] Therefore, the energy conversion unit 30, through the above-described configuration, can drive the generator 306 to generate electricity during the process of opening or closing the upper cover 10, thereby improving the power generation efficiency of the generator 306. At the same time, the method of driving the generator 306 through the elastic portion 302 and the telescopic portion 301 does not cause excessive resistance to the opening or closing of the upper cover 10, allowing the user to conveniently open or close the upper cover 10.

[0081] Further, in order to improve the conversion efficiency of the energy conversion unit 30, continue to refer to Figure 3In the embodiment of the present application, the energy conversion unit 30 further includes a speed increaser 305 ; the speed increaser 305 is arranged between the gear 304 and the generator 306 , and the speed increaser 305 drives the generator 306 to rotate under the drive of the gear 304 .

[0082] The speed increaser 305, also known as a transmission, is a mechanical device used to increase the rotational speed. In the generator set, the speed increaser 305 can convert the low speed of the gear 304 into the high speed required by the generator 306. The speed increaser 305 generally includes an input shaft, a gear set, and an output shaft. The input shaft is connected to the gear 304 and receives the low-speed mechanical energy generated by the rack plate 303 driving the gear 304 to rotate. The gear set is arranged in the speed increaser 305 and includes a multi-stage gear set. Each stage of the gear set consists of a pair of mutually meshing gears, generally including a small gear and a large gear. The small gear is connected to the input shaft, and the large gear is connected to the output shaft. The output shaft is connected to the rotor of the generator 306 and is used to output the high speed after the speed increase to increase the speed of the rotor of the generator 306 and improve the power generation efficiency.

[0083] In the embodiment of the present application, since the opening or closing speed of the upper cover 10 is generally slow during the opening or closing process, by providing a speed increaser 305, the power generation efficiency of the energy conversion unit 30 can be greatly improved, and the effect of the energy conversion unit 30 as a backup power supply can be improved.

[0084] Furthermore, in order to improve the energy storage effect of the energy conversion unit 30, in an embodiment of the present application, the energy conversion unit 30 also includes an energy storage capacitor 307; the energy storage capacitor 307 is electrically connected to the output end of the generator 306, and is used to store the electric energy output by the generator 306.

[0085] In order to store electrical energy, batteries can usually be used, but batteries tend to leak electricity slowly. At the same time, the service life of batteries is relatively limited. In order to increase the service life of the energy conversion unit 30, in the embodiment of the present application, a storage capacitor 307 is used to store the electrical energy generated by the generator 306.

[0086] The energy storage capacitor 307 can be a variety of capacitor types, such as double-layer capacitors, asymmetric capacitors, and supercapacitors. In practical applications, the type of capacitor used can be determined based on actual needs. By using the energy storage capacitor 307, the embodiment of the present application can achieve rapid charging and discharging of the energy conversion unit 30, and its service life far exceeds that of traditional batteries, and can withstand millions of charge and discharge cycles, greatly reducing the maintenance cost of the cabinet.

[0087] For further reference, Figure 3To improve the stability of the output voltage of the energy conversion unit 30 and prevent excessive output current from damaging the load unit 70, in this embodiment of the present application, the energy conversion unit 30 further includes a current-limiting resistor 308. One end of the current-limiting resistor 308 is electrically connected to the output terminal of the energy storage capacitor 307, and the other end is electrically connected to the energy conversion unit power input terminal Vin2 of the power merging unit 50. By providing the current-limiting resistor 308, the output current can be limited, preventing excessive current from burning the load unit 70, thereby extending the service life of the load unit 70.

[0088] In some embodiments, in order to enable the power supply merging unit 50 to effectively control the power output by the system power supply unit 40 and the power output by the energy conversion unit 30, as shown in FIG. Figure 4 As shown, in the embodiment of the present application, the power supply converging unit 50 includes a first N-channel MOS transistor Q1, a second N-channel MOS transistor Q2 and a diode D1; the gate of the first N-channel MOS transistor Q1 is electrically connected to the output end of the system power supply unit 40 through the system power input terminal Vin1; the source of the first N-channel MOS transistor Q1 is grounded; the drain of the first N-channel MOS transistor Q1 is electrically connected to the output end of the energy conversion unit 30 through the energy conversion unit power input terminal Vin2; the drain of the first N-channel MOS transistor Q1 is also electrically connected to the second N-channel MOS transistor Q2. The gate of the trench-type MOS transistor Q2 is electrically connected; the drain of the second N-channel MOS transistor Q2 is electrically connected to the output end of the energy conversion unit 30 through the power input terminal Vin2 of the energy conversion unit; the source of the second N-channel MOS transistor Q2 is electrically connected to the switch unit 60 through the power output terminal Vout of the power supply merging unit; the anode of the diode D1 is electrically connected to the output end of the system power supply unit 40 through the system power input terminal Vin1; and the cathode of the diode D1 is electrically connected to the switch unit 60 through the power output terminal Vout of the power supply merging unit.

[0089] When the system power supply unit 40 outputs power, the first N-channel MOS transistor Q1 is turned on, the gate of the second N-channel MOS transistor Q2 is grounded, and the second N-channel MOS transistor Q2 is turned off; the system power supply unit 40 outputs the combined power to the switch unit 60 through the diode D1; when the system power supply unit 40 loses power, the first N-channel MOS transistor Q1 and the diode D1 are turned off; the gate of the second N-channel MOS transistor Q2 is electrically connected to the output end of the energy conversion unit 30, the second N-channel MOS transistor Q2 is turned on, and the output end of the energy conversion unit 30 outputs the combined power to the switch unit 60 through the second N-channel MOS transistor Q2.

[0090] like Figure 4 As shown, the power converging unit 50 uses an N-channel MOS transistor to control the input power. This transistor is constructed by growing a SiO2 thin film insulating layer on a P-type semiconductor, then using a photolithography process to diffuse two highly doped N-type regions. Electrodes (drain and source) are derived from the N-type regions. A layer of aluminum is plated on the SiO2 thin film insulating layer between the source and drain electrodes to serve as the gate. When no voltage is applied between the gate and source, the two N+ regions of the drain and source are separated by a P-type substrate, acting as two back-to-back PN junctions. The resistance between them is as high as several thousand ohms, meaning there is no conductive channel between the drain and source. In this case, the N-channel MOS transistor is in the off state. When a positive voltage is applied between the gate and source, an electric field is generated between the gate and substrate, connecting the two N+ regions of the drain and source, forming an N-type conductive channel between the drain and source electrodes. The N-channel MOS transistor is now in the on state.

[0091] The anode of the diode D1 is electrically connected to the output end of the system power supply unit 40 through the system power input terminal Vin1; the cathode of the diode D1 is electrically connected to the switch unit 60 through the power output terminal VOUT of the power supply merging unit.

[0092] When the system power supply unit 40 is outputting power, the gate of the first N-channel MOS transistor Q1 is at a high level, and the first N-channel MOS transistor Q1 is in a conductive state, i.e., an N-type conductive channel is formed between the source and drain. Since the gate of the second N-channel MOS transistor Q2 is connected to the drain of the first N-channel MOS transistor Q1, the gate of the second N-channel MOS transistor Q2 is equivalent to being grounded. That is, the gate of the second N-channel MOS transistor Q2 is at a low level, and there is no conductive channel between the drain and source of the second N-channel MOS transistor Q2. The second N-channel MOS transistor Q2 is in a disconnected state, i.e., the output of the energy conversion unit 30 is disconnected from the output of the power supply merging unit 50. Since the system power supply unit 40 is also electrically connected to the diode D1, and the anode of the diode D1 is at a high level, the diode D1 is in a conductive state, which is equivalent to the output of the system power supply unit 40 being electrically connected to the output of the power supply merging unit 50. Therefore, when the system power supply unit 40 outputs power, the power merging unit 50 selects the power output by the system power supply unit 40 as the output power, and supplies power to the load unit 70 through the switch unit 60 .

[0093] When the system power supply unit 40 is powered off, that is, the gate of the first N-channel MOS transistor Q1 is at a low level, the first N-channel MOS transistor Q1 is in a disconnected state, that is, no N-type conductive channel is formed between the source and drain of the first N-channel MOS transistor Q1. At the same time, because the output end of the system power supply unit 40 is connected to the anode of the diode D1, when the system power supply unit 40 is powered off, the diode D1 is also in a disconnected state. Therefore, the output end of the system power supply unit 40 is disconnected from the output end of the power supply merging unit 50.

[0094] Since the first N-channel MOS transistor Q1 is in an off state, the gate of the second N-channel MOS transistor Q2 is electrically connected to the output end of the energy conversion unit 30. Since the output end of the energy conversion unit 30 is in a high-level state, the gate of the second N-channel MOS transistor Q2 is also at a high level, and the second N-channel MOS transistor Q2 is in an on state. That is, an N-type conductive channel is formed between the source and drain of the second N-channel MOS transistor Q2. At the same time, since the output end of the energy conversion unit 30 is connected to the drain of the second N-channel MOS transistor Q2, it is equivalent to the output end of the energy conversion unit 30 being directly electrically connected to the output end of the power supply merging unit 50. The power supply merging unit 50 selects the power output of the energy conversion unit 30 as the output power supply and supplies power to the load unit 70 through the switch unit 60.

[0095] The energy conversion unit 30 provided in the embodiment of the present application selects the power output by the system power supply unit 40 and the energy conversion unit 30 through the first N-channel MOS transistor Q1, the second N-channel MOS transistor Q2 and the diode D1. The structure is simple, ensuring that only one output power supply is used to supply power to the load unit 70, saving electric energy. At the same time, the system power supply unit 40 is preferably used for power supply, and the electric energy of the energy conversion unit 30 is stored to the greatest extent, thereby increasing the power supply time of the energy conversion unit 30.

[0096] For further reference, Figure 4 To improve the stability of the energy conversion unit 30, the power merging unit 50 further includes a first pull-up resistor R1 and a second pull-up resistor R2. One end of the first pull-up resistor R1 is electrically connected to the output of the energy conversion unit 30 via the energy conversion unit power input Vin2, and the other end is electrically connected to the gate of the second N-channel MOS transistor Q2. One end of the second pull-up resistor R2 is electrically connected to the output of the system power unit 40 via the system power input Vin1, and the other end is electrically connected to the gate of the first N-channel MOS transistor Q1. The first pull-up resistor R1 protects the second N-channel MOS transistor Q2, while the second pull-up resistor R2 protects the first N-channel MOS transistor Q1, thereby improving the output level and maintaining circuit stability.

[0097] Furthermore, in some embodiments, in order to improve the usability of the cabinet and further save energy, Figure 2 As shown, the switch unit 60 includes a sensor and an automatic switch; the sensor is arranged at a position opposite to the upper cover 10 at the opening of the box body 20 and is electrically connected to the automatic switch; the sensor detects the opening and closing states of the upper cover 10, and when the upper cover 10 is opened, the automatic switch is controlled to connect the power supply confluence unit 50 with the load unit 70; when the upper cover 10 is closed, the automatic switch is controlled to disconnect the power supply confluence unit 50 from the load unit 70.

[0098] The sensor may be a Hall effect sensor, a spring switch sensor, or the like. When the upper cover 10 is opened, the sensor detects the state of the upper cover 10 and generates a control signal to control the automatic switch. The automatic switch may be a relay switch or a magnetic switch. The automatic switch can operate automatically under the control of the control signal, eliminating manual operation.

[0099] The embodiment of the present application can automatically detect the status of the upper cover 10 by setting a sensor and an automatic switch. Only when the upper cover 10 is opened, the power supply merging unit 50 provides power to the load unit 70, which greatly saves energy consumption and improves the service life of the system power supply unit 40.

[0100] In some embodiments, the switch unit 60 includes a manual switch; the manual switch includes a switch button, and the switch button is used to control the disconnection and connection between the power supply merging unit 50 and the load unit 70.

[0101] The manual switch is highly reliable and not prone to damage. Therefore, it can be installed separately. Alternatively, it can be installed on the cabinet 20 together with the automatic switch. When the automatic switch is functioning properly, the power supply to the load unit 70 is controlled by the automatic switch. When the automatic switch is damaged, the manual switch takes over control, thereby improving the reliability of the cabinet.

[0102] In some embodiments of the present application, an electronic system is further provided, which includes the cabinet and electronic equipment proposed in any of the above embodiments, and the cabinet is used to accommodate the electronic equipment.
