Description

Technical Field

[0001] This invention relates to the field of energy storage power supplies, and in particular to a wall-mounted household energy storage power supply. Background Technology

[0002] Traditional energy storage power supplies typically use lithium-ion battery modules, which are formed by connecting cylindrical or prismatic lithium-ion batteries in series and parallel according to voltage and current requirements. However, in existing lithium-ion battery modules, all cells are arranged in multiple layers, resulting in a large size and low volume utilization, which is detrimental to improving energy density. Summary of the Invention

[0003] The purpose of this invention is to provide a wall-mounted household energy storage power supply to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wall-mounted household energy storage power supply, comprising a chassis and a cover, wherein a first support member, a support frame, and a second support member are sequentially arranged inside the chassis along the direction of gravity, the two ends of the support frame being detachably mounted on the first support member and the second support member, respectively, a back plate assembly being sandwiched between the support frame and the inner wall of the chassis, and a limiting assembly being provided between the support frame and the cover, the limiting assembly comprising a plurality of pressure plates evenly spaced, the two ends of the pressure plates being detachably connected to the two ends of the support frame, a battery cavity being recessed in the middle of the end of the support frame near the limiting assembly, two insulating plates parallel to the cover being provided in the battery cavity, a plurality of blade battery packs being stacked between the two insulating plates, each blade battery pack comprising a plurality of blade cell units arranged side by side along the extension direction of the pressure plates, all the blade cell units being connected in series through a connecting assembly to form a battery module, a control module electrically connected to the battery module being provided on the side of the first support member away from the second support member, and a power indicator device electrically connected to the control module being provided on the inner wall of the cover. By stacking multiple blade battery packs in an orderly manner, and then fixing the blade cell units in the battery cavity with a support frame and pressure plate, the structure used for fixing is reduced while ensuring the fixing strength. In addition, the blade batteries are sheet-shaped and can be tightly connected when stacked, which greatly reduces the gap between the batteries during fixing. This effectively reduces the volume of the battery module under the same voltage and current conditions, making the overall chassis thinner and flatter, effectively reducing the volume of the entire energy storage power supply, and correspondingly improving the energy density and volume utilization of the battery module.

[0005] Furthermore, the battery cavity is equipped with insulating components that correspond one-to-one with the blade battery packs. Adjacent insulating components are centrally symmetrical. Each insulating component includes a first insulating element and a second insulating element. Each blade battery pack is disposed between the first and second insulating elements. A first insulating sheet is sandwiched between adjacent blade battery packs. The center of symmetry of two adjacent insulating components is coplanar with the plane containing the insulating sheet. The maximum dimension of the first insulating element extending along the pressure plate is a first length, and the maximum dimension of the second insulating element extending along the pressure plate is a second length. The first length is less than the second length. The first and second insulating elements clamp and fix the components within the battery cavity, separating adjacent blade battery packs. The first and second insulating elements, along with the first insulating sheet, also separate adjacent blade battery packs, preventing safety hazards caused by excessively small gaps between the blade batteries.

[0006] Furthermore, the power indicator device includes a lamp panel and a light guide plate. The lamp panel is detachably mounted on the inside of the cover, and a light guide plate is sandwiched between the lamp panel and the cover. The lamp panel has a plurality of light-emitting units evenly spaced. The surface of the light guide plate near the lamp panel has grooves that correspond to the light-emitting units with a clearance fit. The surface of the light guide plate away from the lamp panel has protruding color light guides that correspond to the light-emitting units. The cover has patterned grooves through which all the color light guides can pass. When the lamp panel is powered on, the light emitted by the light-emitting units will be conducted through the light guide plate. The light guide plate conducts the light emitted by the lamp panel to the color light guides on the cover, causing the corresponding color light guides to emit different colors of light. The different colors of the color light guides indicate the range of the remaining power of the battery module. The color light guides on the light guide plate will light up according to the amount of power during the charging and discharging process. The number and total length of the color light guides that emit light will be determined according to the amount of power during the charging and discharging process. When the power is low, the light-emitting unit at the leftmost or rightmost end will light up, causing its corresponding color light guide to emit red or orange light.

[0007] Furthermore, the first insulating component is a PC insulating sheet, and the second insulating component includes an EVA insulating foam sheet and a cuboid-shaped support rod. The EVA insulating foam sheet is sandwiched between the support rod and the blade battery cell unit. The support rod is a hollow sheet metal rod or an EVA foam rod. The second insulating component is provided with EVA insulating foam, which has high elasticity. The blade battery pack causes the EVA insulating foam to undergo elastic deformation, and the EVA insulating foam applies elastic force to the blade battery pack. The blade battery pack is clamped and fixed in the battery cavity by the first insulating component and the second insulating component.

[0008] Furthermore, the blade cell unit is rectangular, and both its length and width are greater than the depth of the battery cavity. The blade cell unit has a flat, rectangular structure. When arranged within the battery cavity, the thickness of the blade cell unit is parallel to the extension direction of the battery cavity. The blade cell units are laid flat within the battery cavity, flattening the blade battery pack and reducing the thickness of the chassis and battery module.

[0009] Furthermore, each of the light-emitting units includes an LED chip and a transparent resin layer. The transparent resin layer is disposed within a groove, and the LED chip is disposed inside the transparent resin layer. The space enclosed by the lamp board, the LED chip, and the groove is filled with a transparent resin layer. The LED chip in each groove is encapsulated by the transparent resin layer, so that the LED chip and the transparent resin layer form a preset pattern shape. The LED chip is encapsulated with transparent optical resin, and the light emitted by the LED chip is conducted through the transparent optical resin, so that the transparent resin layer emits light uniformly. The light emitted by the transparent resin layer illuminates the light guide plate, and the color light guide parts at corresponding positions on the light guide plate emit light of different colors.

[0010] Furthermore, the inner wall of the box cover is provided with several protruding posts, and both the lamp plate and the light guide plate have through holes for the corresponding protruding posts to pass through. Each protruding post is detachably connected to a limiting member that is interference-fitted with the through hole. An external thread is provided on the protruding post, and a nut is selected as the limiting member. The limiting member has a threaded hole, and the protruding post and the limiting member are threaded together to fix the lamp plate and the light guide plate to the box cover. Alternatively, a rubber collar is selected as the limiting member, and a through hole adapted to the protruding post is provided on the limiting member. The limiting member is fitted onto the protruding post to fix the lamp plate and the light guide plate to the box cover. The protruding posts sequentially pass through the light guide plate and the lamp plate, and the lamp plate and the light guide plate are positioned by the cooperation of the protruding posts and the through holes.

[0011] Furthermore, the connecting assembly includes a first connecting piece and a second connecting piece. A plurality of first connecting pieces are evenly spaced at one end of the battery cavity, and a plurality of second connecting pieces are evenly spaced at the other end of the battery cavity. The number of blade battery packs within the battery cavity is two layers, with each blade battery pack disposed between the first and second connecting pieces. The first and second connecting pieces have positive and negative contacts at their respective ends. The first connecting pieces connect the blade battery cells in series via the second connecting pieces to form a battery module.

[0012] Furthermore, the backplate assembly includes a first insulating plate, a reinforcing plate, and a second insulating plate arranged sequentially along the extension direction of the pressure plate. A first bracket and a second bracket are spaced apart on the back of the chassis. The first bracket is fixedly connected to a first support member, and the second bracket is fixedly connected to the reinforcing plate. Both ends of the first support member are bent to provide connecting plates that contact the inner wall of the chassis. The reinforcing plate thickens the connection between the second bracket and the chassis, and the connecting plates thicken the connection between the first bracket and the chassis. This design reduces the chassis structure while ensuring chassis strength, thus contributing to the lightweight design of the chassis.

[0013] Furthermore, the left and right ends of the chassis are respectively provided with a first fixing bracket and a second fixing bracket recessed inward. The first fixing bracket has a positive interface and a negative interface. The negative interface is electrically connected to the control module, and the positive interface is electrically connected to the battery module. The second fixing bracket has a DB25 interface electrically connected to the control module. The energy storage power supply and peripheral devices are connected in series and in parallel through the DB25 interface. This design avoids exposing the DB25 interface, positive interface, and negative interface on the outer surface of the chassis. The concealed design of the DB25 interface, positive interface, and negative interface prevents collisions with external objects during transportation of the energy storage power supply.

[0014] The beneficial effects of this invention are as follows: by stacking multiple blade battery packs in an orderly manner, and then fixing the blade cell unit in the battery cavity by a support frame and a pressure plate, the structure used for fixing is reduced while ensuring the fixing strength, which facilitates quick assembly and disassembly of the whole machine. The blade cell unit is fixed in the middle position in the chassis by the support frame and multiple pressure plates. The support frame, insulating plate, pressure plate and chassis and other components provide multi-layer protection for the blade cell unit, which improves the stability of the cell unit in the battery module and the safety of the multi-layer protection of the cell.

[0015] The color light guide on the light guide plate will light up according to the amount of electricity during the charging and discharging process. The number and total length of the light-emitting color light guide will be determined according to the amount of electricity during the charging and discharging process. When the power is insufficient, the light-emitting unit at the leftmost or rightmost end will light up, causing the corresponding color light guide to emit red or orange light.

[0016] Furthermore, the blade battery is in the form of a sheet, which can be tightly connected when stacked, greatly reducing the gap between batteries when fixed. This effectively reduces the volume of the battery module under the same voltage and current conditions, making the overall chassis thinner and flatter, effectively reducing the volume of the entire energy storage power supply, and correspondingly improving the energy density and volume utilization of the battery module.

Detailed Implementation

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

"Inner" and "outer" refer to the inner and outer parts of a specific outline. "Far" and "near" refer to the distance or proximity relative to a particular component.

[0025] like Figures 1-3As shown in the figure, an embodiment of the present invention provides a wall-mounted household energy storage power supply, including a chassis 1 and a cover 2. Inside the chassis 1, a first support member 3, a support frame 4, and a second support member 5 are sequentially arranged along the direction of gravity. The two ends of the support frame 4 are detachably mounted on the first support member 3 and the second support member 5, respectively. A back plate assembly is sandwiched between the support frame 4 and the inner wall of the chassis 1. A limiting assembly is provided between the support frame 4 and the cover 2. An insulating plate 7 is sandwiched between the support frame 4 and the limiting assembly. The limiting assembly includes a plurality of pressure plates 6 evenly spaced, with each pressure plate 6 detachably connected to one end of the support frame 4. An electrical... The battery cavity contains two insulating plates 7 parallel to the cover 2. Several blade battery packs are stacked between the two insulating plates 7. Each blade battery pack 11 includes several blade cell units 12 arranged side by side along the extension direction of the pressure plate 6. All the blade cell units 12 are connected in series through the connecting component 8 to form a battery module. The insulating plate 7 is sandwiched between the support frame 4 and the surface of the battery module away from the cover 2. The support frame 4 has several hollow weight-reducing grooves. The side of the first support member 3 away from the second support member 5 is provided with a control module 10 electrically connected to the battery module. The inner wall of the cover 2 is provided with a power indicator device 9 electrically connected to the control module 10. By stacking multiple blade battery packs in an orderly manner, and then fixing the blade cell unit 12 in the battery cavity by the support frame 4 and the pressure plate 6, the structure used for fixing is reduced while ensuring the fixing strength. In addition, the blade battery is in the shape of a sheet, and can be tightly connected together when stacked, which greatly reduces the gap between the batteries during fixing. This effectively reduces the volume of the battery module under the same voltage and current conditions, making the overall chassis 1 thinner and flatter, effectively reducing the volume of the entire energy storage power supply, and correspondingly improving the energy density and volume utilization of the battery module.

[0026] In one embodiment, the middle part of the pressure plate is detachably connected to the box cover by a first screw, and the upper and lower ends of the pressure plate are detachably connected to the first support member and the second support member by a first bolt, respectively. The first bolt passes through the upper and lower ends of the support frame. The box cover has a through groove for the first screw to pass through, and the box cover is provided with a decorative plate. The decorative plate and the through groove are snap-fit ​​connected one-to-one.

[0027] The battery cavity is equipped with stacked insulating components corresponding to the blade battery packs. Adjacent insulating components are centrally symmetrical. Each insulating component includes a first insulating element and a second insulating element 13. Each blade battery pack is disposed between the first insulating element and the second insulating element 13. A first insulating sheet is sandwiched between adjacent blade battery packs. The center of symmetry of two adjacent insulating components is coplanar with the plane of the insulating sheet. The maximum dimension of the first insulating element extending along the pressure plate 6 is a first length, and the maximum dimension of the second insulating element 13 extending along the pressure plate 6 is a second length. The first length is less than the second length. The first insulating element and the second insulating element 13 clamp and fix the battery packs within the battery cavity, separating adjacent blade battery packs 11. The first insulating element and the second insulating element 13, along with the first insulating sheet, also separate adjacent blade battery packs 11, preventing safety hazards caused by excessively small gaps between the blade batteries.

[0028] The power indicator 9 includes a lamp panel and a light guide plate. The lamp panel is detachably mounted on the inner side of the cover 2, and a light guide plate is sandwiched between the lamp panel and the cover 2. The lamp panel has a plurality of light-emitting units evenly spaced. The surface of the light guide plate near the lamp panel has grooves that correspond to the light-emitting units with a gap fit. The surface of the light guide plate away from the lamp panel has protruding color light guides that correspond to the light-emitting units. The cover 2 has patterned grooves through which all the color light guides can pass. When the lamp panel is powered on, the light emitted by the light-emitting units will be conducted through the light guide plate. The light guide plate conducts the light emitted by the lamp panel to the color light guides on the cover 2, causing the corresponding color light guides to emit different colors of light. The different colors of the color light guides indicate the range of the remaining power of the battery module. The color light guides on the light guide plate will light up according to the amount of power during the charging and discharging process. The number and total length of the color light guides that emit light will be determined according to the amount of power during the charging and discharging process. When the power is low, the light-emitting unit at the leftmost or rightmost end will light up, causing its corresponding color light guide to emit red or orange light.

[0029] In one embodiment, the leftmost or rightmost color light guide is set to red or orange, and the remaining color light guides are set to the same color, for example, the remaining color light guides are set to green. The number of illuminated light-emitting units changes according to the amount of battery power during the charging and discharging process, thereby illuminating the color light guides on the light guide plate according to the amount of power during the charging and discharging process. When the power is insufficient, the leftmost or rightmost light-emitting unit will light up, causing its corresponding color light guide to emit red or orange light.

[0030] The first insulating component is a PC insulating sheet, and the second insulating component 13 includes an EVA insulating foam sheet and a cuboid-shaped support rod. The EVA insulating foam sheet is sandwiched between the support rod and the blade battery cell unit 12. The support rod is a hollow sheet metal rod or an EVA foam rod. The second insulating component 13 is provided with EVA insulating foam, which has high elasticity. The blade battery pack 11 causes the EVA insulating foam to undergo elastic deformation, and the EVA insulating foam applies elastic force to the blade battery pack 11. The blade battery pack 11 is clamped and fixed in the battery cavity by the first insulating component and the second insulating component 13.

[0031] The blade battery cell unit 12 is rectangular, and both its length and width are greater than the depth of the battery cavity. The blade battery cell unit 12 has a flat, rectangular structure. When arranged within the battery cavity, the thickness of the blade battery cell unit 12 is parallel to the extension direction of the battery cavity. The blade battery cell unit 12 is laid flat within the battery cavity, thus flattening the blade battery pack 11 and reducing the thickness of the chassis 1 and the battery module.

[0032] Each of the light-emitting units includes an LED chip and a transparent resin layer. The transparent resin layer is disposed within a groove, and the LED chip is disposed inside the transparent resin layer. The space enclosed by the light panel, the LED chip, and the groove is filled with a transparent resin layer. The LED chip in each groove is encapsulated by the transparent resin layer, so that the LED chip and the transparent resin layer form a preset pattern shape. The LED chip is encapsulated with transparent optical resin, and the light emitted by the LED chip is conducted through the transparent optical resin, so that the transparent resin layer emits light uniformly. The light emitted by the transparent resin layer shines on the light guide plate, and the color light guide parts at corresponding positions on the light guide plate emit light of different colors.

[0033] The inner wall of the cover 2 is provided with several protruding posts. Both the lamp plate and the light guide plate have through holes for each protruding post to pass through. Each protruding post is detachably connected to a limiting member that is interference-fitted with the through hole. An external thread is provided on the protruding post, and a nut is selected as the limiting member. The limiting member has a threaded hole, and the protruding post and the limiting member are threaded together to fix the lamp plate and light guide plate to the cover 2. Alternatively, a rubber collar is selected as the limiting member, and a through hole adapted to the protruding post is provided. The limiting member is fitted onto the protruding post to fix the lamp plate and light guide plate to the cover 2. The protruding posts sequentially pass through the light guide plate and the lamp plate, and the lamp plate and light guide plate are positioned by the cooperation of the protruding posts and the through holes.

A plurality of first connecting pieces 81 are evenly spaced at one end of the battery cavity, and a plurality of second connecting pieces 82 are evenly spaced at the other end of the battery cavity. The number of blade battery packs within the battery cavity is two layers, each blade battery pack being disposed between the first connecting pieces 81 and the second connecting pieces 82. Positive and negative contacts are respectively provided at both ends of the first connecting pieces 81 and the second connecting pieces 82. The first connecting pieces 81 connect the blade battery cells 12 in series through the second connecting pieces 82 to form a battery module.

[0035] The backplate assembly includes a first insulating plate 7, a reinforcing plate, and a second insulating plate 7 arranged sequentially along the extension direction of the pressure plate 6. A first bracket and a second bracket are spaced apart on the back of the chassis 1. The first bracket is fixedly connected to a first support member 3, and the second bracket is fixedly connected to the reinforcing plate. Both ends of the first support member 3 are bent to form connecting plates that contact the inner wall of the chassis 1. The reinforcing plate thickens the connection between the second bracket and the chassis 1, and the connecting plates thicken the connection between the first bracket and the chassis 1. This design reduces the structural bulk of the chassis 1 while ensuring its strength, thus contributing to its lightweight design.

[0036] In one embodiment, the limiting component further includes several transverse plates, the extension direction of which is perpendicular to the extension direction of the pressure plate. The transverse plates and the pressure plate are integrally formed. The two ends of the pressure plate are detachably connected to the first support member and the second support member by second bolts. The upper and lower ends of the support frame are provided with through holes for the second bolts to pass through. Both ends of the transverse plates are bent into folded plates in the direction away from the cover. The folded plates at both ends of the transverse plates are detachably connected to the chassis by screws. The inner wall of the chassis is provided with screw holes that are compatible with the screws.

[0037] The chassis 1 has a first fixing frame and a second fixing frame recessed inward at its left and right ends, respectively. The first fixing frame contains a positive interface and a negative interface. The negative interface is electrically connected to the control module 10, and the positive interface is electrically connected to the battery module. The second fixing frame contains a DB25 interface, which is electrically connected to the control module 10. The energy storage power supply and peripheral devices are connected in series and in parallel through the DB25 interface. This design avoids exposing the DB25 interface, positive interface, and negative interface on the outer surface of the chassis 1. The concealed design of the DB25 interface, positive interface, and negative interface prevents collisions with external objects during transportation of the energy storage power supply.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
