Description

Technical Field

[0001] The present invention belongs to the technical field of power supplies, and particularly relates to a power supply and an automatic regulation current sharing module for power supply health management. Background Art

[0002] A power supply is a device that converts other forms of energy into electrical energy. Based on the principle of "magnetic induction generating electricity", power sources include renewable energy sources such as hydropower, wind power, ocean tides, water pressure differences in dams, solar energy, as well as power generation from burning coal, oil residues, etc. Common power supplies are dry batteries (direct current) and household 110V - 220V alternating current power supplies. Power supplies are divided into: ordinary power supplies and special power supplies. Among them, special power supplies can be further subdivided into: shore power supplies, security power supplies, high - voltage power supplies, medical power supplies, military power supplies, aerospace power supplies, laser power supplies, and other special power supplies.

[0003] In some special environments, such as military equipment and power grid systems, special power supplies are required, which are special types of power supplies. The so - called special mainly lies in that the technical index requirements for measuring the power supply are different from those of common power supplies. Mainly, the output voltage is extremely high, the output current is extremely large, or the requirements for stability, dynamic response, and ripple are extremely high, or the power supply is required to output a pulsed voltage or current or some other requirements. This makes the design and production of such power supplies have more special and even stricter requirements than ordinary power supplies. However, existing special power supplies generally lack protection devices, and are easily damaged by humans or some animals during use, thus causing damage to the internal component structure of the special power supply, affecting the use of the special power supply in special scenarios, and in serious cases, may cause huge accidents, bringing certain economic losses to the country.

[0004] Therefore, in view of the above - mentioned technical problems, it is necessary to provide a power supply and an automatic regulation current sharing module for power supply health management. Summary of the Invention

[0005] The purpose of the present invention is to provide a power supply and an automatic regulation current sharing module for power supply health management, so as to solve the problem that existing special power supplies are easily damaged by humans or animals due to the lack of protection devices, thus causing huge accidents.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A power supply includes a power supply body, and a protection mechanism is provided outside the power supply body. The protection mechanism includes a protective shell with a hollow interior. An installation plate is provided inside the protective shell, and the installation plate is slidably connected to the protective shell. The protective shell is provided with a plurality of protective plates and heat dissipation holes. A multiple buffer protection mechanism matching the protective plates is provided inside the protective shell. The multiple buffer protection mechanism includes a contact plate, and a plurality of uniformly distributed activity cavities are drilled in the contact plate. A warning mechanism is slidably connected in the activity cavity;

[0008] The warning mechanism includes a movable column. A limiting block is connected to the side wall of the activity cavity of the movable column. A spring is connected between the limiting block and the contact plate, and the spring is sleeved outside the movable column. One side of the movable column away from the protective plate is connected with a pressing plate. A metal particle layer is provided on the side of the contact plate close to the power supply body, and a non-Newtonian body layer is connected to the metal particle layer.

[0009] Further, a handle buckle is connected to the installation plate, which is convenient for the user to pull the installation plate and place the power supply body on the installation plate.

[0010] Further, the number of the protective plates is four, and the protective plates are respectively arranged on the side wall and the upper top surface of the protective shell, which is convenient for protecting the power supply body from multiple angles and avoiding the power supply body being damaged by humans or animals.

[0011] Further, a reinforcing member is connected between a pair of the multiple buffer protection mechanisms, which greatly increases the overall strength of the protective shell and avoids the protective shell being damaged.

[0012] Further, a cavity is formed between the contact plate and the metal particle layer, and a buffer layer is filled in the cavity, which is convenient for further protecting the power supply body and avoiding the power supply body being damaged. The pressing plate penetrates through the buffer layer.

[0013] Further, a pair of magnets are provided in the pressing plate, and the magnetic distance of the magnets is less than the distance between the contact plate and the metal particle layer. When the pressing plate slides to a certain distance, the magnets attract the metal particle layer, so as to increase the extrusion area of the pressing plate on the non-Newtonian body layer and facilitate further buffering of the external force on the protective shell.

[0014] A power supply health management automatic current sharing module includes the power supply described above. A current sharing module is provided inside the power supply. The current sharing module includes a switching power supply circuit, a temperature detection module, a data transmission and analysis module, a carrier communication module, a host computer, a voltage extraction module, a voltage division adjustment circuit, and an output voltage VBUS. The temperature detection module is electrically connected to the switching power supply circuit and the data transmission and analysis module respectively. The data transmission and analysis module is electrically connected to the voltage division adjustment circuit through the voltage extraction module. The voltage division adjustment circuit is electrically connected to the output voltage VBUS.

[0015] Further, the temperature detection module includes a temperature detection chip PT1, which is electrically connected to the switching power supply circuit and is used to detect various devices in the switching power supply circuit.

[0016] Further, the data transmission and analysis module includes a main control chip U1, which is electrically connected to the upper computer through a carrier communication module. It can cooperate with the upper computer. After inputting the model of the input device, according to the internally established database and the data collected by the temperature detection chip PT1, it can automatically calculate the system life and can also adjust the current of the voltage extraction chip U2.

[0017] Further, the voltage extraction module includes a voltage extraction chip U2, and the carrier communication module includes a power line carrier transmission chip U3.

[0033] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0034] The present invention discloses a power supply, as shown in Figures 1 - 5 including a power supply body 1, a protection mechanism 2 for protecting the power supply body 1, and a warning mechanism 3 for warning and prompting.

[0035] As shown in Figures 1 - 4As shown in the figure, a protection mechanism 2 is provided outside the power supply body 1. The protection mechanism 2 includes a protective shell 201. The inside of the protective shell 201 is hollow. An installation plate 202 is provided inside the protective shell 201. A handle buckle is connected to the installation plate 202, which is convenient for the user to pull the installation plate 202, facilitating the placement of the power supply body 1 on the installation plate 202. The installation plate 202 is slidably connected to the protective shell 201. A plurality of protective plates 203 and heat dissipation holes 204 are provided on the protective shell 201. The protective plates 203 are made of transparent material, and the number of protective plates 203 is four. The protective plates 203 are respectively arranged on the side wall and the top surface of the protective shell 201, facilitating multi-angle protection of the power supply body 1 and preventing the power supply body 1 from being damaged by humans or animals. The heat dissipation holes 204 are used to dissipate heat from the power supply body 1, preventing the power supply body 1 from being damaged due to excessive temperature. A multi-layer buffer protection mechanism matching the protective plates 203 is provided inside the protective shell 201. The multi-layer buffer protection mechanism includes a contact plate 205, which is used to buffer the force received by the protective shell 201 and prevent external force from being transmitted to the power supply body 1, causing damage to the power supply body 1. A plurality of uniformly distributed activity cavities 206 are drilled on the contact plate 205, which are used to further buffer the external force received by the protective shell 201.

[0036] Among them, a reinforcing member is connected between a pair of multi-layer buffer protection mechanisms, greatly increasing the overall strength of the protective shell 201 and preventing the protective shell 201 from being damaged.

[0037] Refer Figures 3 - 5 As shown in the figure, a cavity is formed between the contact plate 205 and the metal particle layer 207. A buffer layer 208 is filled in the cavity, facilitating further protection of the power supply body 1 and preventing the power supply body 1 from being damaged. The extrusion plate 304 penetrates through the buffer layer 208. A metal particle layer 207 is provided on the side of the contact plate 205 close to the power supply body 1, and a non-Newtonian body layer 209 is connected to the metal particle layer 207.

[0038] Refer Figures 3 - 4As shown in the figure, a warning mechanism 3 is slidably connected inside the movable cavity 206. The warning mechanism 3 includes a movable column 301. The movable column 301 is in contact with the protection plate 203. A limiting block 302 is connected to the side wall of the movable cavity 206 where the movable column 301 is located. A spring 303 is connected between the limiting block 302 and the contact plate 205. The spring 303 is sleeved outside the movable column 301. A pressing plate 304 is connected to the side of the movable column 301 away from the protection plate 203. When the protection plate 203 is impacted by an external force, the movable column 301 in contact with the protection plate 203 can play a role in sharing the pressure and reduce the force received by the movable column 301. At the same time, under the action of the limiting block 302 and the spring 303, the movable column 301 slides a certain distance, which can further buffer the external impact force. When the distance between the pressing plate 304 and the metal particle layer 207 is less than the magnetic force of the magnet 308, the magnet 308 can attract the metal particle layer 207, and the metal particle layer 207 adheres concentratedly to the side close to the pressing plate 304, making the area of the pressing plate 304 larger, so as to increase the extrusion force on the non-Newtonian body layer 209. Utilizing the characteristics of the non-Newtonian body layer 209, the external force is further buffered to prevent the external acting force from acting on the power supply body 1.

[0039] As shown Figure 4 As shown in the figure, a pair of magnets 308 are provided inside the pressing plate 304. The magnetic distance of the magnets 308 is less than the distance between the contact plate 205 and the metal particle layer 207. When the pressing plate 304 slides a certain distance, the magnets 308 attract the metal particle layer 207, thereby increasing the extrusion area of the pressing plate 304 on the non-Newtonian body layer 209, facilitating further buffering of the external force on the protective shell 201.

[0040] Specifically, a low-power power supply is provided inside the protective shell 201. The voltage of the low-power power supply is 24V, which is within the range of the safe voltage for the human body. The low-power power supply is electrically connected to the metal particle layer 207, enabling the metal particle layer 207 to be charged during use. A metal sheet 210 matching the pressing plate 304 is provided on the side of the metal particle layer 207 close to the protection plate 203. A wire 211 is connected between the metal sheet 210 and the metal particle layer 207. Since the metal particle layer 207 has conductivity, the wire 211 is also charged.

[0041] As shown Figure 4As shown in the figure, a lamp holder 305 is connected to the side of the movable column 301 close to the protection plate 203, and a contact 306 is connected to the pressing plate 304. A connecting wire 307 is connected between the lamp holder 305 and the contact 306. When the pressing plate 304 is externally pressed, the contact 306 contacts the metal sheet 210, so that a closed circuit is formed by the low-power power supply, the metal particle layer 207, and the lamp holder 305, making the lamp holder 305 charged and emit light. The brightness of the lamp holder 305 is irradiated through the protection plate 203, facilitating the user to accurately judge the position where the protective shell 201 is externally pressed.

[0042] During specific use, when an external force presses the protection plate 203, the pressing force received by the protection plate 203 is divided into the warning mechanism 3. Since the movable column 301 is in contact with the protection plate 203, under the action of the limit block 302 and the spring 303, the movable column 301 slides in the movable cavity 206. The sliding of the movable column 301 drives the pressing plate 304 to displace. When the pressing plate 304 slides a certain distance, the magnetic force of the magnet 308 attracts the metal particle layer 207, enabling the metal particle layer 207 to be concentrated and adhered to the side close to the pressing plate 304. At this time, the contact 306 on the pressing plate 304 contacts the metal sheet 210 on the surface of the metal particle layer 207. Since the low-power power supply in the protective shell 201 is electrically connected to the metal particle layer 207, and a wire 211 is connected between the metal particle layer 207 and the metal sheet 210, the surface of the metal sheet 210 is charged. When the contact 306 contacts the metal sheet 210, electricity passes through the contact 306 and the connecting wire 307, making the lamp holder 305 emit light. Since the protection plate 203 is made of a transparent material, it is convenient for the user to observe the light of the lamp holder 305 from the outside and accurately judge the position where the protective shell 201 is affected by the external force. Since the metal particle layer 207 is concentrated and adhered to one side of the pressing plate 304, the overall area of the pressing plate 304 is enlarged, increasing the extrusion of the non-Newtonian body layer 209 by the pressing plate 304. The non-Newtonian body layer 209 is used to buffer the external force, preventing the external force from directly acting on the power supply body 1, thereby protecting the power supply body 1 and preventing the power supply body 1 from being damaged.

The temperature detection module is electrically connected to both the switching power supply circuit and the data transmission and analysis module. The data transmission and analysis module is electrically connected to the voltage division adjustment circuit through the voltage extraction module. The voltage division adjustment circuit is electrically connected to the output voltage VBUS. The internal multi - point temperature is monitored by the temperature sensor in the temperature detection module. For the main heat - generating components inside the power supply, such as power transistors, capacitors, transformers, etc., the temperature is monitored and calculated in real - time, and the result is fed back to the main control chip U1 of the data transmission and analysis module. The main control chip U1 reports the calculated result to the host computer through the carrier communication module. The host computer aggregates and sorts all the power supply data in the circuit and feeds back the result to the main control chip U1 of each data transmission and analysis module. After receiving the feedback instruction, the main control chip U1 will automatically adjust the voltage extraction ratio of the voltage extraction module according to the data gap between itself and other modules to control the voltage division adjustment circuit, adjust the output voltage of each load, and adjust the output current of each power supply module until all modules work at the same operating temperature.
