Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power supplies, and specifically to a safe and stable wall-mounted household energy storage power supply. Background Technique

[0002] People's dependence on electricity is increasing. To avoid having no power when a power outage occurs, people use household energy storage power supplies to supply power to devices such as laptops, mobile phones, etc. Generally, household energy storage power supplies are hung on the outside of the wall through hooks or bolts, thereby reducing the space occupied by the household energy storage power supply. And the household energy storage power supply needs to be charged first before it can be discharged for use. However, there are still certain defects in the use of existing household energy storage power supplies, such as:

[0003] The utility model patent publication number CN215817622U discloses a wall-mounted household energy storage power supply, which optimizes the placement method of the battery cells, increases the reliability and use safety of the wall-mounted household energy storage power supply, and avoids the situation that the output end and communication interface of the wall-mounted household energy storage power supply are easily collided during movement. At the same time, it also extends the service life of the wall-mounted household energy storage power supply.

[0004] For another example, the utility model patent publication number CN217522148U discloses a wall-mounted household energy storage power supply. The energy storage power supply can quickly install the lithium battery control board, adapter board and each battery module into the chassis through the lithium battery control board and the adapter board, which is beneficial to improving production efficiency. And the whole chassis is hung on the hanger pre-installed on the wall, and during the process of overhauling the energy storage power supply, the whole chassis can be quickly disassembled and installed.

[0005] In Comparative Document 1 (publication number CN215817622U) and Comparative Document 2 (publication number CN217522148U), the batteries inside the energy storage power supply are installed inside the energy storage power supply through battery protection boards, and the battery protection boards are connected to the shell of the energy storage power supply. And the battery protection boards are mostly flat structures. When the battery accidentally catches fire or explodes, it is easy to cause the whole energy storage power supply to catch fire and be damaged, which is likely to affect personal safety, resulting in limited safety in the use of the energy storage power supply.

[0006] In view of the above problems, it is urgent to innovate and design on the basis of the original energy storage power supply structure. Summary of the Invention

[0007] The purpose of the present invention is to provide a safe and stable wall-mounted household energy storage power supply to solve the problems mentioned in the above background technique, that is, when the battery accidentally catches fire or explodes, it is easy to cause the whole energy storage power supply to catch fire and be damaged, which is likely to affect personal safety, resulting in limited safety in the use of the energy storage power supply.

[0008] To achieve the above object, the present invention provides the following technical solution: A safe and stable wall-mounted household energy storage power supply, comprising a housing, a control panel and a protective shell. The front end of the housing is fixedly installed with a control panel, and the inside of the housing is fixedly installed with a protective shell. A charging port and a power supply port are respectively opened inside the housing, and the charging port is located on the left side of the power supply port. Three mounting frames are fixedly installed inside the protective shell, through holes are opened in the upper two mounting frames, and battery assemblies are fixedly installed inside the mounting frames. A driving motor is fixedly installed inside the housing, a rotating cylinder is fixedly installed at the output end of the driving motor, a turntable is fixedly installed on the outer side of the right end of the rotating cylinder, and a fixing groove is opened inside the lower end of the turntable. A fixing block is fixedly installed on the inner surface of the upper end of the protective shell, a support spring is fixedly installed inside the fixing block, and a limiting block is fixedly installed at the lower end of the support spring. A discharge port is opened at the upper end of the rotating cylinder.

[0009] Preferably, two mounting brackets are fixedly installed on the outer side of the rear end of the housing, limiting grooves are respectively opened inside the mounting brackets, and limiting rods are slidably installed inside the lower ends of the mounting brackets. A connecting rod is fixedly installed on one side of the limiting rod close to the middle position of the housing, and a moving cylinder is sleeved on the outer side of the connecting rod. By providing mounting brackets at the rear end of the outer shell, it is convenient to install the energy storage power supply on the outer side of the wall. And by providing movable limiting rods inside the mounting brackets, bolts or hanging rods can be limited inside the mounting brackets by moving the limiting rods, thereby effectively improving the installation stability of the energy storage power supply.

[0010] Preferably, two fixing plates are fixedly installed on the outer side of the right end of the housing, a limiting member is slidably installed inside the fixing plates, a clamping groove is opened inside the limiting member, a return spring is sleeved on the outer side of the limiting member, and the limiting member is located on the right side of the two power supply ports. By providing a movable limiting member on the outer side of the power supply port, the line connector inserted into the power supply port can be limited, thereby effectively improving the connection stability between the energy storage power supply and the line during the discharging process.

[0011] Preferably, through holes are equidistantly arranged inside the mounting frame, and three mounting frames are equidistantly arranged inside the protective shell. The protective shell is made of aluminum alloy, and the mounting frame is made of insulating plastic. The equidistant arrangement of through holes inside the mounting frame allows the quartz sand at the upper end of the mounting frame to continue to flow downward through the through holes. The aluminum alloy material of the protective shell can effectively improve the explosion-proof effect of the energy storage power supply, and the insulating plastic material of the mounting frame can improve the insulation effect of the energy storage power supply.

[0012] Preferably, the outer surface of the upper end of the rotary drum is provided with discharge ports at equal angles, and the rotary drum and the turntable are coaxial structures. Moreover, the fixing groove inside the turntable is located at the lower end of the turntable. Meanwhile, the inside of the rotary drum is filled with quartz sand, which enables the quartz sand inside to scatter through the discharge ports after the rotary drum rotates, and enables the turntable to rotate synchronously when the rotary drum rotates.

[0013] Preferably, the limiting block and the fixing block form an elastic structure through a support spring. The limiting block and the turntable form a clamping structure through the fixing groove. Moreover, the height of the limiting block is greater than that of the fixing groove, and the limiting block is in close contact with the outer surface of the turntable. The limiting block and the fixing block forming an elastic structure through the support spring can push the limiting block to slide inside the fixing block through the support spring, while the limiting block and the turntable forming a clamping structure through the fixing groove can enable the limiting block to be clamped with the turntable through the fixing groove and limit the turntable.

[0014] Preferably, two groups of limiting grooves are symmetrically arranged about the vertical central axis of the mounting frame. The mounting frame is slidably connected to the limiting rod. Moreover, two groups of the mounting frame and the limiting rod are arranged on the outer side of the rear end of the housing. The two groups of limiting grooves symmetrically arranged about the vertical central axis of the mounting frame facilitate the stable installation through the two groups of limiting grooves. The slidable connection between the mounting frame and the limiting rod enables the limiting rod to slide inside the mounting frame. During the sliding process of the limiting rod, bolts or hanging rods can be limited inside the mounting frame, thereby preventing the energy storage power supply from falling during the process of being pushed.

[0015] Preferably, the moving cylinder is threadedly connected to the two connecting rods. The thread rotation directions of the two connecting rods are opposite. Moreover, the connecting rods are slidably connected to the mounting frame. Meanwhile, the two connecting rods are symmetrically arranged above and below the horizontal central axis of the moving cylinder. The threaded connection between the moving cylinder and the two connecting rods enables the two connecting rods to move in the opposite direction when the moving cylinder moves. The slidable connection between the connecting rods and the mounting frame enables the connecting rods to push the limiting rod to move inside the mounting frame during the rotation process.

[0016] Preferably, the limiting member and the fixing plate form an elastic structure through a return spring. The two card slots inside the limiting member are correspondingly arranged with the two power supply ports. Moreover, the limiting member is in close contact with the outer sides of the power supply ports. Meanwhile, the limiting member is located between the two fixing plates. The limiting member and the fixing plate forming an elastic structure through the return spring can push the limiting member to slide inside the fixing plate through the return spring. The two card slots inside the limiting member being correspondingly arranged with the two power supply ports facilitates the fixation of the end of the line through the card slots and limits the line at the same time. The close contact between the limiting member and the outer sides of the power supply ports facilitates the end of the line.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the process of positioning and installing the safe and stable wall-mounted household energy storage power supply, the limiting groove can be located outside the bolt or hook through the mounting bracket. Then, the moving cylinder can be rotated. During the rotation of the two groups of moving cylinders, the bolt will move inside the mounting bracket and push the limiting rod to move. During the movement of the limiting rod, it will contact the bolt or hook and limit the bolt or hook inside the mounting bracket. At this time, the energy storage power supply can be fixedly installed at the required position, thus effectively improving the installation stability of the energy storage power supply.

[0019] 2. When the battery module inside the safe and stable wall-mounted household energy storage power supply accidentally catches fire or explodes, the protective shell made of aluminum alloy can effectively prevent the entire energy storage power supply from exploding and reduce the impact of the battery module catching fire or exploding. During this process, the driving motor will drive the rotating cylinder to rotate and make the discharge port located at the lower end of the rotating cylinder. The quartz sand inside the rotating cylinder will fall onto the upper ends of the battery module and the mounting frame. At this time, the quartz sand on the upper end of the mounting frame will continue to flow downward through the through holes, so that the quartz sand wraps the battery module. During the rotation of the turntable, it will be clamped with the limiting block and limit the rotating cylinder at this position, which can make the coverage of the quartz sand on the battery module accurate, and then effectively improve the explosion-proof and fire-proof effect of the energy storage power supply and ensure the safety of the energy storage power supply during use.

[0020] 3. When the safe and stable wall-mounted household energy storage power supply is supplying power, pushing the limiting member to move can make the power supply port in an open state. During the movement of the moving member, the reset spring will be in a contracted state. After the power supply wire is docked with the power supply port, the limiting member can be released. At this time, the reset spring pushes the limiting member to move to the outside of the end of the power supply wire and limits the end of the power supply wire, which can prevent the power supply wire from separating from the power supply port after being accidentally pulled, thus effectively ensuring the stability of the energy storage power supply during the power supply process.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-10 , the present invention provides a technical solution: a safe and stable wall-mounted household energy storage power supply, including a shell 1, a control panel 2, a protective shell 3, a charging port 4, a power supply port 5, a mounting frame 6, a through hole 7, a battery assembly 8, a driving motor 9, a rotating cylinder 10, a turntable 11, a fixed groove 12, a fixed block 13, a support spring 14, a limiting block 15, a mounting bracket 16, a limiting groove 17, a limiting rod 18, a connecting rod 19, a moving cylinder 20, a fixed plate 21, a limiting member 22, a card slot 23, a return spring 24 and a discharge port 25.

[0034] On the outer side of the rear end of the housing 1, two sets of mounting brackets 16 are fixedly installed. Limiting grooves 17 are provided inside each of the mounting brackets 16. A limiting rod 18 is slidably installed inside the lower end of the mounting bracket 16. On one side of the limiting rod 18 close to the middle position of the housing 1, a connecting rod 19 is fixedly installed. A moving cylinder 20 is sleeved outside the connecting rod 19. Two sets of limiting grooves 17 are symmetrically arranged about the vertical central axis of the mounting bracket 16. The mounting bracket 16 is slidably connected to the limiting rod 18. Two sets of the mounting bracket 16 and the limiting rod 18 are provided on the outer side of the rear end of the housing 1. The moving cylinder 20 is threadedly connected to the two connecting rods 19. The thread rotation directions of the two connecting rods 19 are opposite. The connecting rod 19 is slidably connected to the mounting bracket 16. At the same time, the two connecting rods 19 are symmetrically arranged above and below the horizontal central axis of the moving cylinder 20.

[0035] According to Figures 5-8 , when using this safe and stable wall-mounted household energy storage power supply, first install the energy storage power supply at the position where it needs to work. When the existing energy storage power supply is installed, it is generally directly hung outside the bolt or hook. During the process of the energy storage power supply being touched or pushed by children, there is a risk of the energy storage power supply falling, resulting in limited installation stability of the energy storage power supply. During the installation process of the energy storage power supply, first install the bolt or hook used to hang the mounting bracket 16 inside the wall. After the installation is completed, the energy storage power supply can be installed through the mounting bracket 16. During the installation process, the limiting groove 17 is sleeved outside the bolt or hook. After placing the bolt or hook inside the mounting bracket 16, the moving cylinder 20 can be rotated. During the rotation of the moving cylinder 20, the connecting rod 19 inside the moving cylinder 20 will move. During the movement of the connecting rod 19, the limiting rod 18 will be pushed to slide inside the mounting bracket 16. When the limiting rod 18 slides, it will contact the hook or bolt (the dotted line structure 8 in the figure). After the limiting rod 18 contacts the bolt or hook, the bolt or hook will be limited inside the mounting bracket 16. At this time, the mounting bracket 16 cannot move outside the bolt or hook, thus completing the installation process of the energy storage power supply. When disassembling the energy storage power supply, the user can reverse-rotate the moving cylinder 20 to separate the limiting rod 18 from the bolt or hook, and then the energy storage power supply can be disassembled. Through the movement of the limiting rod 18 and the mounting bracket 16, the energy storage power supply can be effectively fixed at the required position, thus effectively improving the installation stability of the energy storage power supply.

[0036] A control panel 2 is fixedly installed at the front end of the housing 1, and a protective case 3 is fixedly installed inside the housing 1. A charging port 4 and a power supply port 5 are respectively provided inside the housing 1, and the charging port 4 is located on the left side of the power supply port 5. Three mounting frames 6 are fixedly installed inside the protective case 3, and through holes 7 are provided inside the upper two mounting frames 6. A battery assembly 8 is fixedly installed inside the mounting frame 6. A drive motor 9 is fixedly installed inside the housing 1, and a rotating cylinder 10 is fixedly installed at the output end of the drive motor 9. A turntable 11 is fixedly installed on the outer side of the right end of the rotating cylinder 10. A fixing groove 12 is provided inside the lower end of the turntable 11. A fixing block 13 is fixedly installed on the inner surface of the upper end of the protective case 3, and a support spring 14 is fixedly installed inside the fixing block 13. A limiting block 15 is fixedly installed at the lower end of the support spring 14. A discharge port 25 is provided at the upper end of the rotating cylinder 10. Through holes 7 are equidistantly arranged inside the mounting frame 6, and three mounting frames 6 are equidistantly arranged inside the protective case 3. The protective case 3 is made of aluminum alloy, and the mounting frame 6 is made of insulating plastic. Discharge ports 25 are arranged at equal angles on the outer surface of the upper end of the rotating cylinder 10. The rotating cylinder 10 and the turntable 11 are coaxial structures. The fixing groove 12 inside the turntable 11 is located at the exact lower end of the turntable 11. Quartz sand is contained inside the rotating cylinder 10. The limiting block 15 and the fixing block 13 form an elastic structure through the support spring 14. The limiting block 15 and the turntable 11 form a clamping structure through the fixing groove 12. The height of the limiting block 15 is greater than the height of the fixing groove 12. The limiting block 15 is in close contact with the outer surface of the turntable 11.

[0037] According to Figures 1-5 and Figures 9-10, during the use of the energy storage power supply, the battery assembly 8 inside the energy storage power supply is composed of multiple mini lithium batteries. During use, there may be a situation where a lithium battery is accidentally damaged, causing a short circuit in the internal circuit of the energy storage battery. At this time, the battery assembly 8 may cause spontaneous combustion or explosion. The protective shell 3 is made of aluminum alloy structure, which can effectively reduce the impact of the explosion of the internal battery of the energy storage power supply on the outside world. And when the battery assembly 8 causes spontaneous combustion or explosion, it will cause the internal temperature of the energy storage power supply to rise rapidly or there will be open flames. The temperature sensor and flame detector inside the control panel 2 will receive this information and transmit it to the controller inside the control panel 2. At this time, the controller inside the control panel 2 will make the drive motor 9 work. During the work of the drive motor 9, it will drive the rotary drum 10 to rotate quickly by 180 degrees. After the rotary drum 10 finishes rotating, the discharge port 25 will be located at the lower end of the rotary drum 10. At this time, the quartz sand inside the rotary drum 10 will be discharged through the discharge port 25. The quartz sand will flow on the upper ends of the battery assembly 8 and the mounting frame 6, and the quartz sand located on the upper end of the mounting frame 6 will continue to flow downward through the through hole 7, so that quartz sand accumulates on the upper ends of the three groups of battery assemblies 8, thus isolating oxygen from contacting the battery assembly 8, and effectively controlling the open flames generated by the battery assembly 8. During the rotation of the rotary drum 10, it will drive the turntable 11 to rotate. During the rotation of the turntable 11, the fixed slot 12 will rotate from the lower end of the turntable 11 to the upper end of the turntable 11. After the turntable 11 stops rotating, the compressed support spring 14 will expand and push the limit block 15 to move. During the movement of the limit block 15, it will enter the inside of the fixed slot 12 and engage with the turntable 11. At this time, the turntable 11 can be limited in this position. By limiting the turntable 11, it can effectively prevent the discharge port 25 from deviating during the rotation of the rotary drum 10, resulting in the quartz sand inside the rotary drum 10 being unable to be discharged or discharged insufficiently, affecting the fire extinguishing effect of the quartz sand on the battery assembly 8. Through the movement of the protective shell 3, the rotary drum 10 and the turntable 11, the accuracy of the quartz sand covering the battery assembly 8 can be improved, and then the explosion-proof and fire-proof effects of the energy storage power supply can be effectively improved, ensuring the safety of the use of the energy storage power supply.

[0038] Two groups of fixing plates 21 are fixedly installed on the outer side of the right end of the housing 1, and a limiting member 22 is slidably installed inside the fixing plate 21. A clamping groove 23 is opened inside the limiting member 22, and a return spring 24 is sleeved on the outer side of the limiting member 22. And the limiting member 22 is located on the right side of the two power supply ports 5. The limiting member 22 and the fixing plate 21 form an elastic structure through the return spring 24. The two clamping grooves 23 inside the limiting member 22 are correspondingly arranged with the two power supply ports 5, and the limiting member 22 is in close fit with the outer sides of the power supply ports 5. At the same time, the limiting member 22 is located between the two fixing plates 21.

[0039] According toFigures 1-2 and Figures 4-5 , before the energy storage power supply supplies power, the energy storage power supply needs to be charged through the charging port 4. Only after the energy storage power supply is fully charged can it be used to supply power. During the process of making the energy storage power supply supply power, the power supply wire needs to be docked with the power supply port 5. Before the power supply wire is docked with the power supply port 5, it is necessary to push the limiting member 22 to move. During the movement of the limiting member 22, it will slide inside the fixing plate 21 and squeeze the return spring 24. After the return spring 24 is squeezed, it will contract. During this process, the limiting member 22 will move away from the power supply port 5. Then, the end of the power supply wire can be inserted into the power supply port 5. After the power supply wire is docked with the power supply port 5, release the limiting member 22. At this time, the contracted return spring 24 will expand and push the limiting member 22 to move. During the movement of the limiting member 22, it will move to the initial position and make the circuit of the power supply wire located inside the card slot 23. After the limiting member 22 moves to the initial position, it will closely fit with the end of the power supply wire, thereby limiting the end of the power supply wire inside the power supply port 5, and preventing the power supply wire from separating from the power supply port 5 after being accidentally pulled, thus effectively ensuring the stability of the energy storage power supply during the power supply process and increasing the overall practicability.
