In this way of heat dissipation, the heat on the motherboard cannot be effectively exchanged with the cold air. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the present invention provides a novel household energy storage device to solve the problems raised in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A novel household energy storage device includes a box body, wherein the box body has a storage battery and a mainboard, wherein the mainboard is electrically connected to the storage battery through a cable, wherein the mainboard is fixedly mounted on one side of the box body, wherein an end cover is mounted on one end of the box body, wherein a hole is provided on the end cover, and wherein the mainboard is mounted close to the end cover; wherein a blowing assembly is arranged between the mainboard and the end cover, wherein the blowing assembly comprises:

[0009] A frame is installed between the mainboard and the end cover. By setting the frame on the mainboard and installing a fan at the end of the frame, a certain space is left between the fan and the mainboard, so that the heat generated by the mainboard can be exchanged with the cold air. The hot air is then exchanged with the cold air outside the box through the fan, thereby improving the heat dissipation efficiency; and

DETAILED DESCRIPTION

[0035] Example:

[0036] See also Figure 1-3 A novel household energy storage device includes a box 100, wherein the box 100 has a storage battery 110 and a main board 130, wherein the main board 130 is electrically connected to the storage battery 110 through a cable, wherein the main board 130 is fixedly mounted on one side of the box 100, wherein an end cover 120 is mounted at one end of the box 100, wherein the end cover 120 is provided with a hole for ventilation and heat dissipation, wherein the main board 130 is mounted close to the end cover 120; wherein a blowing assembly 200 is arranged between the main board 130 and the end cover 120, wherein the blowing assembly 200 includes:

[0037] The frame 210 is installed between the main board 130 and the end cover 120. Figure 3 As shown, the frame 210 is hollowed out as a whole, so that when the fan 220 described below is in operation, the heat generated by the mainboard 130 and the battery 110 can enter the frame 210 under the negative pressure of the fan 220, and then be drawn out of the box 100 by the fan 220, thereby achieving efficient heat dissipation. In order to achieve a better heat transfer effect, the frame 210 can be made of metal. When the frame 210 is made of metal, the heat generated by the mainboard 130 can be transferred to the frame 210, thereby increasing the heat conduction area, and then the fan 220 blows air to the frame 210 and the mainboard 130, thereby increasing the heat dissipation rate;

[0038] A fan 220 is installed at one end of the frame 210 away from the mainboard 130. The fan 220 has a drive motor that can drive the blades of the fan 220 to rotate;

[0039] A driving rod 230, the middle of which is connected to the rotating shaft of the fan 220, and the center of the driving rod 230 is connected to the center of the rotating shaft of the fan 220 as the fan 220 rotates synchronously, so as to achieve good stability and not easily generate noise (when the driving rods 230 are installed asymmetrically, they may generate unbalanced forces when rotating, thereby causing vibration and noise);

[0040] A brush is mounted on one end of the driving rod 230 close to the end cover 120. When the driving rod 230 rotates synchronously with the fan 220, the end of the brush on the driving rod 230 contacts the end cover 120 and scrapes the surface of the end cover 120.

[0041] Through the above solution, when the brush rotates, the end of the brush contacts the surface of the end cover 120. When the brush rotates with the driving rod 230, the inner surface of the end cover 120 can be scraped to achieve the cleaning effect.

[0042] Continue reading Figure 4 As a possible embodiment, the brush is slidably mounted on the driving rod 230, and a telescopic member is mounted on one end of the brush, and the telescopic member drives the brush to slide on the driving rod 230;

[0043] Through the above solution, when the brush rotates with the driving rod 230, the brush slides back and forth on the driving rod 230 under the action of the telescopic member, so that more cleaning area can be covered, so that all parts of the end cover 120 can be cleaned;

[0044] It should be noted that the telescopic member may be an electric telescopic rod, a hydraulic telescopic rod, a pneumatic telescopic rod or other members having a telescopic effect.

[0045] like Figure 4-6 As shown, the brush includes a movable block 231, a connecting rod 234 and bristles 235, wherein the bristles 235 are connected to the connecting rod 234, and the connecting rod 234 is connected to the movable block 231, and the bristles 235 are hollow and pass through one end of the connecting rod 234 close to the fan 220;

[0046] By setting the middle part of the bristles 235 to be hollow and passing through the open end of the bristles 235, the connecting rod 234 and the movable block 231, when the fan 220 is operating, the generated wind can be blown through the middle part of the bristles 235 to the open end of the bristles 235, so that the open end of the bristles 235 is always kept clean and tidy.

[0047] like Figure 4 As shown, a sliding groove 232 is formed on the driving rod 230, the movable block 231 is slidably connected to the sliding groove 232, and an elastic member 233 is connected between the movable block 231 and the inner wall of the sliding groove 232;

[0048] It should be noted that the elastic member 233 may be a spring or elastic;

[0049] The brushes are mounted at both ends of the driving rod 230, and under the action of centrifugal force, the brushes are thrown toward both ends of the driving rod 230;

[0050] By setting the elastic member 233, when the driving rod 230 rotates with the fan 220, the elastic member 233 is stretched under the action of centrifugal force, so that the brush can slide to the two ends of the driving rod 230, and during the sliding process, the brush can also generate friction with the end cover 120 in a new direction (this direction is the center line direction of the driving rod 230), thereby improving the cleaning effect.

[0051] like Figure 2-3 As shown, as a possible embodiment, the frame 210 and the fan 220 on the mainboard 130 have at least two, and at least one group of fans 220 has opposite wind directions;

[0052] Through the above scheme, the wind generated by one of the fans 220 blows toward the mainboard 130, thereby effectively cooling the mainboard 130 and dissipating the heat on the mainboard 130, and then the hot air is sucked out of the box 100 through other fans 220 with wind directions facing outward. Compared with existing means, the heat dissipation efficiency is higher and the space for heat exchange is larger.

[0053] Continue reading Figure 7 As a possible embodiment, one end of the bristle 235 close to the end cover 120 is connected to an elastic wire 2351, and the elastic wire 2351 is connected around the end of the bristle 235 to form a circumferential arrangement;

[0054] It should be noted that the elastic material mentioned above can be metal or plastic.

[0055] like Figure 2 As shown, the mainboard 130 is also connected to a charging interface module 140, and the charging interface module 140 is located on one side of the frame 210. The end cover 120 is provided with an opening matching the charging interface module 140, and the open end of the charging interface module 140 is buckled with the opening.

[0056] like Figure 1 As shown, a handle 150 is provided on the top of the box body 100, and the end cover 120 is connected by screws, bolts or welding;

[0057] The above welding methods can be the following:

[0058] 1) Friction welding: Use friction heat to melt and soften the plastic contact surface, and then pressurize it to solidify. This method can be used for welding straight welds and flat welds;

[0059] 2) Ultrasonic welding: Use high-frequency mechanical energy to soften or melt thermoplastics at the joints. The connected parts are fixed together under pressure, and then subjected to ultrasonic vibrations with a frequency of usually 20 or 40 kHz. The transducer converts the high-power vibration signal into corresponding mechanical energy and applies it to the contact interface of the plastic parts to be welded. The weld joints are violently rubbed to generate high heat instantly, so that the molecules alternately fuse, thereby achieving the welding effect. The ultrasonic welding process is very fast, the welding time is less than one second, and it is easy to automate. It is widely used in various industries such as electronics, electrical appliances, auto parts, plastic toys, stationery, daily necessities, handicrafts, cosmetics, etc.

[0060] 3) Laser welding: Use a laser beam to melt and soften the plastic contact surface, and then pressurize it to solidify. This method can be used for welding straight welds and flat welds.

[0061] 4) Electron beam welding: Use electron beam to melt and soften the plastic contact surface, and then pressurize it to solidify. This method can be used for welding straight welds and flat welds.

[0062] 5) Hot pressure welding: The plastic is heated to a molten state, and then a heating plate is pressed on it to make it solidify quickly. This method can be used for welding straight welds and flat welds.

[0063] The following situations may occur due to collision or compression of the battery:

[0064] 1) Battery pack deformation: The battery pack may deform after being hit or squeezed, which will affect the capacity and performance of the battery;

[0065] 2) Battery short circuit: Impact or squeezing may cause the battery to short circuit, resulting in fire or explosion, which is usually caused by chemical reactions inside the battery;

[0066] 3) Battery gassing: Squeezing may cause the release of gas inside the battery, resulting in battery gassing, which ultimately affects the performance of the battery;

[0067] 4) Insulation failure: Impact or extrusion may cause battery insulation failure, resulting in short circuit or fire;

[0068] Therefore, a possible embodiment is provided, such as Figure 2 As shown, there is a pad 300 between the battery 110 and the box 100. The pad 300 is made of a soft material. The inside of the pad 300 is hollow. An air inlet 310 is provided at one end of the pad 300.

[0069] The pad 300 may be made of rubber or silicone material. Gas is injected into the hollow of the pad 300 through the air inlet 310 to cause the pad 300 to expand to a certain extent, so that the pad 300 has stronger elasticity and improves the buffering performance.

[0070] According to the above solution, since the battery 110 and the inner wall of the box body 100 are supported by the pad 300, when the battery 110 falls or collides, the pad 300 can effectively protect the battery 110 from damage through the buffering effect of the pad 300.
