Description

Technical Field

[0001] The present invention relates to the technical field of power supplies, and more particularly to a household power supply. Background Art

[0002] Household electricity is supplied by the municipal power grid. However, in some areas where power outages are prone to occur or in some areas that use green energy, a household power supply is usually prepared at home. When not in use, the household power supply can be connected to solar equipment for power storage. When there is a power outage, insufficient power supply, or a need to reduce electricity costs, the household power supply can be directly used.

[0003] However, the existing household power supply has a fixed capacitance and cannot flexibly adjust the capacitance value according to requirements. When the power consumption demand is large, such a household power supply cannot continuously supply power and needs to wait for it to charge, affecting the overall user experience.

[0004] Therefore, the present invention provides a household power supply. Summary of the Invention

[0018] Preferably, the structure of the lower protection cover is the same as that of the upper protection cover, the structure of the first trigger assembly is the same as that of the second trigger assembly, and the center of the top of the trigger rod and the center of the bottom of the first trigger assembly are on the same vertical line.

[0019] The beneficial effects of the present invention are as follows: For a household power supply described in the present invention, by providing an operation box assembly, a stacked power supply assembly and a base assembly, the operation box assembly and the base assembly are essential components of this power supply, and the stacked power supply assembly is an optional component. The number of stacked power supply assemblies can be flexibly adjusted according to requirements. When the power consumption demand is small, some stacked power supply assemblies can be disassembled to reduce the overall floor area of the power supply; when the power consumption demand is large, an appropriate number of stacked power supply assemblies can be selected and stacked according to the actual situation to provide stable power supply for a period of time. The remaining stacked power supply assemblies in the idle period can perform power storage operations during this period and then be alternately replaced after being used for a period of time, so as to achieve continuous and stable power supply.

[0020] For a household power supply described in the present invention, by providing a stacked power supply assembly, the plug block and the socket are matched with each other, and the baffle is inserted into the socket slot, so as to guide the stacking of two stacked power supply assemblies. When the plug block is completely inserted into the inner side of the socket slot of the socket, the top of the power supply main body is in close contact with the bottom of the socket. At this time, the first electrical plug and the second electrical plug are plugged in, making the stacking more stable.

[0021] A household power supply according to the present invention is provided with a lower protection component and an upper protection component. During the process of connecting the first and last ends of two stacked power supply components, the top of the trigger rod first contacts the bottom of the first trigger component. When the top of the trigger rod is pressed, it moves. The top of the trigger rod pushes the driving rod downward, and the bottom of the trigger rod pushes the center of the first trigger component upward, so as to expose the second electrical plug and the first electrical plug for electrical connection of two stacked power supply components. When the trigger rod is not pressed, that is, when the stacked power supply components are in an idle state, the top of the trigger rod loses the extrusion force. Under the action of the second torsion spring and the first torsion spring, the lower protection cover and the upper protection cover reset and respectively cover the bottom of the installation square groove and the top of the enclosure to protect the second electrical plug and the first electrical plug.

It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and the functions and arrangements of the elements discussed can be changed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0033] Embodiment

[0034] The technical solution of the present invention will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. Please refer to Figures 1 to 8 A household power supply provided by the present application. Please pay special attention to referring to Figure 1 and Figure 2 It includes an operation box assembly 1. The operation box assembly 1 includes a box body 101. A display screen 102 for displaying values is installed on the front of the box body 101. A wiring terminal 103 for wiring is provided on the back of the box body 101. A superimposed power supply assembly 2 is arranged at the bottom of the operation box assembly 1. The number of the superimposed power supply assemblies 2 is selected according to the required capacitance and stacked at the bottom of the operation box assembly 1. A base assembly 3 is placed at the bottom of the superimposed power supply assembly 2 at the bottommost layer.

[0035] Specifically, the operation box component 1 and the base component 3 are essential components of this power supply, and the stacked power supply component 2 is an optional component. The number of stacked power supply components 2 can be flexibly adjusted according to requirements. When the power consumption demand is low, some stacked power supply components 2 can be disassembled to reduce the overall floor area of the power supply; when the power consumption demand is high, an appropriate number of stacked power supply components 2 can be stacked according to the actual situation to provide stable power supply for a period of time. The remaining stacked power supply components 2 in the idle period can perform power storage operations during this period and then be alternately replaced after being used for a period of time, so as to achieve continuous and stable power supply.

[0036] Please refer specifically to Figure 3 、 Figure 4 , the stacked power supply component 2 includes a main plug-in mating structure and an upper plug-in mating structure. The main plug-in mating structure of the stacked power supply component 2 includes a power supply main body 201, a lower fixing ring 204, a plug socket 205, a hidden handle 206, a mounting square groove 209, and a second electrical plug 2010. The bottom of the power supply main body 201 is fixedly connected to the top of the lower fixing ring 204. The plug socket 205 is fixedly connected to the four corners inside the lower fixing ring 204. The mounting square groove 209 is opened at the bottom of the power supply main body 201. The second electrical plug 2010 is fixedly installed on the top wall of the mounting square groove 209. The structure of the box body 101 is the same as that of the main plug-in mating structure of the stacked power supply component 2.

[0037] Specifically, two adjacent stacked power supply components 2 are stacked end to end to increase the overall capacitance of the power supply. During the stacking process, the upper plug-in mating structure of the stacked power supply component 2 at the top and the main plug-in mating structure of the stacked power supply component 2 at the bottom cooperate with each other for positioning.

[0038] Please refer specifically to Figure 3 、 Figure 4 , the upper plug-in mating structure of the stacked power supply component 2 includes a baffle 202, a plug block 203, a retaining wall 207, and a first electrical plug 208. The baffle 202 is fixedly connected to the four corners at the top of the power supply main body 201. The bottom of the plug socket 205 is provided with a plug slot that has a clearance fit with the plug block 203. The plug block 203 is located on one side of each baffle 202 away from the center of the top of the power supply main body 201. The first electrical plug 208 is installed on the top of the power supply main body 201. The retaining wall 207 is fixedly connected to the top of the power supply main body 201. The retaining wall 207 is located around the first electrical plug 208.

[0039] Specifically, there is a clearance fit between one side of the baffle 202 away from the center of the power supply main body 201 and one side of the socket 205 close to the center of the power supply main body 201. The heights of the lower fixing ring 204, the socket 205, the baffle 202, the plug 203, and the socket groove of the socket 205 are the same. During the stacking process where two stacked power supply components 2 are connected end to end, the plug 203 cooperates with the socket 205, and the baffle 202 cooperates with the socket groove of the socket 205 to guide the stacking of the two stacked power supply components 2. When the plug 203 is completely inserted into the inner side of the socket groove of the socket 205, the top of the power supply main body 201 is in close contact with the bottom of the socket 205. At this time, the first electrical plug connector 208 and the second electrical plug connector 2010 are plugged in completely.

[0040] Please refer specifically to Figure 1 、 Figure 2 , the base assembly 3 includes a seat body 301, and moving wheels 302 are installed at the four corners of the bottom of the seat body 301.

[0041] Specifically, the provision of the moving wheels 302 facilitates the movement of the entire power supply.

[0042] Please refer specifically to Figure 3 、 Figure 4 , an upper protection assembly 5 for protecting the first electrical plug connector 208 is provided at the top of the power supply main body 201, and a lower protection assembly 4 for protecting the second electrical plug connector 2010 is provided at the bottom of the power supply main body 201. During the process where two stacked power supply components 2 to be plugged are connected end to end, the upper protection assembly 5 and the lower protection assembly 4 move synchronously to expose the first electrical plug connector 208 and the second electrical plug connector 2010 respectively for electrical connection.

[0043] Specifically, when the idle stacked power supply components 2 are not in use and not in the power storage state, the first electrical plug connector 208 and the second electrical plug connector 2010 are exposed to the outside and will be contaminated by external dust and moisture. The metal surface is prone to oxidation and corrosion, which will increase the contact resistance, reduce the conductivity, and even cause the connection to fail. At this time, the first electrical plug connector 208 and the second electrical plug connector 2010 need to be replaced, which will increase the usage cost. By providing the lower protection assembly 4 and the upper protection assembly 5, when the stacked power supply components 2 are not in use and not in the power storage state, the upper protection assembly 5 and the lower protection assembly 4 protect the first electrical plug connector 208 and the second electrical plug connector 2010 respectively to ensure effective electrical connection during stacking.

[0044] Please refer specifically to Figure 5 、 Figure 6, the upper protection component 5 includes an upper protection cover 501 and an annular fixing seat 505. The upper protection cover 501 is slidably connected to the top of the inner wall of the enclosure 207. At the bottom of the other side of the upper protection cover 501, a second connecting wire 502 is fixedly connected. At the bottom of the second connecting wire 502, a second trigger component 503 is connected. The annular fixing seat 505 is fixedly connected to the top of the power supply main body 201. A trigger rod 506 is movably inserted through the top of the annular fixing seat 505. At the bottom of the second trigger component 503, a second torsion spring 504 is connected.

[0045] Please refer specifically to Figure 6 , the upper protection cover 501 includes two support frames 5015. A transition roller is rotatably connected between the two support frames 5015. On the outer side of the transition roller, a cover body 5011 is arranged. On one side of the cover body 5011, a cross bar 5012 is fixedly connected. On the front and back of the cross bar 5012, convex blocks 5013 are fixedly connected. On the inner walls of the front and back of the enclosure 207, sliding grooves that are in clearance fit with the convex blocks 5013 are respectively opened. On the other side of the convex block 5013, a spring 5014 is fixedly connected. The bottom of the cover body 5011 is fixedly connected to the top of the second connecting wire 502.

[0046] Specifically, one end of the spring 5014 is fixedly connected to the convex block 5013, and the other end of the spring 5014 is fixedly connected to the inner wall of the enclosure 207. The widths of the cross bar 5012, the cover body 5011, the transition roller, and the inner width of the enclosure 207 are all in clearance fit. On the top of the power supply main body 201, a storage groove that is in clearance fit with the cover body 5011 is opened. When the second connecting wire 502 pulls the cover body 5011 to slide down, the cross bar 5012 moves along the sliding groove, and the first electrical plug connector 208 is exposed. In this embodiment, the cover body 5011 is made of a flexible material.

[0047] Please refer specifically to Figure 6 , Figure 7 , the second trigger component 503 includes an outer sleeve 5034. A thread groove 5035 is opened on the outer side of the outer sleeve 5034. A driving rod 5032 is movably inserted through the inner side of the outer sleeve 5034. At the top of the outer side of the driving rod 5032, a driving block 5033 is fixedly connected. The outer diameter of the driving block 5033 is in clearance fit with the thread width of the thread groove 5035. At the bottom of the driving rod 5032, a winding roller 5031 is fixedly connected. The top of the outer side of the outer sleeve 5034 is fixedly connected to the inner bottom of the annular fixing seat 505. The outer diameter of the trigger rod 506 is the same as the outer diameter of the driving rod 5032.

[0048] Specifically, the inner diameter of the outer sleeve 5034 and the outer diameter of the driving rod 5032 are in clearance fit. During the process of connecting the two superimposed power supply components 2 end to end, the trigger rod 506 is first pressed and moves downward, thereby squeezing the driving rod 5032 to move downward. However, since a driving block 5033 is provided on the outer side of the driving rod 5032 and the driving block 5033 is slidably connected to the inner side of the thread groove 5035, under the limitation of the thread groove 5035, the driving rod 5032 rotates and moves downward along the thread groove 5035, thereby driving the winding roller 5031 to rotate and move downward, winding the bottom of the second connecting wire 502 on the outer side of the winding roller 5031 and receiving the cover body 5011 inside the sliding groove, and exposing the first electrical plug 208. During this process, the superimposed power supply component 2 itself has a certain weight, which is sufficient to stably press the trigger rod 506 through the weight of the superimposed power supply component 2.

[0049] Please refer specifically to Figure 8 , the lower protection component 4 includes a lower protection cover 401. The bottom of the other side of the lower protection cover 401 is fixedly connected to a first connecting wire 402. The other side of the first connecting wire 402 is fixedly connected to a first trigger component 403. The top of the first trigger component 403 is fixedly connected to a first torsion spring 404. The other side of the bottom of the power supply main body 201 is provided with a second installation groove that is in transitional fit with the outer side of the bottom of the first trigger component 403. The outer side of the bottom of the first trigger component 403 is fixedly connected to the bottom of the second installation groove. The other side of the installation square groove 209 is provided with a second moving groove that is in clearance fit with the lower protection cover 401. In this embodiment, the lower protection cover 401 is made of a flexible material.

[0050] Specifically, the lower protection cover 401 can move along the second moving groove under the pulling of the first connecting wire 402. As Figure 8 shown, the top wall of the second installation groove is fixedly connected to the top of the first torsion spring 404, and the inner top of the first trigger component 403 moves along the second installation groove when rotating upward. Specifically, during the process of connecting the two superimposed power supply components 2 end to end, the top of the trigger rod 506 first contacts the bottom of the first trigger component 403. The top of the trigger rod 506 is pressed and moves. The top of the trigger rod 506 pushes the driving rod 5032 downward, and the bottom of the trigger rod 506 pushes the center of the first trigger component 403 upward. And when the trigger rod 506 is not pressed, that is, when the superimposed power supply component 2 is in an idle state, the top of the trigger rod 506 loses the extrusion force. Under the action of the second torsion spring 504 and the first torsion spring 404, the lower protection cover 401 and the upper protection cover 501 respectively cover the bottom of the first electrical plug 208 and the top of the enclosure 207.

[0051] Please refer specifically to Figure 3 , Figure 4 , Figure 8, the structure of the lower protective cover 401 is the same as that of the upper protective cover 501, the structure of the first trigger assembly 403 is the same as that of the second trigger assembly 503, and the center of the top of the trigger rod 506 is on the same vertical line as the center of the bottom of the first trigger assembly 403.

[0052] Specifically, during the process of the two stacked power supply assemblies 2 to be plugged in being connected end to end, the trigger rod 506 contacts the bottom of the first trigger assembly 403 and pushes the inner side of the first trigger assembly 403 to rotate and rise. The principle is the same as that of the second trigger assembly 503, so that the second connecting wire 502 is wound around the outside of the top of the first trigger assembly 403, thereby pulling the lower protective cover 401 to retract into the power supply main body 201 to expose the second electrical plug 2010. At this time, the bottom of the trigger rod 506 presses down to successively trigger the second trigger assembly 503 to rotate and descend to expose the first electrical plug 208. When the two stacked power supply assemblies 2 are completely connected end to end, the top of the annular fixing seat 505 is in close contact with the outer bottom of the first trigger assembly 403, and the second electrical plug 2010 and the first electrical plug 208 just complete the plugging action to achieve electrical connection.

[0053] Working principle: The operation box assembly 1 and the base assembly 3 are essential components of this power supply, and the stacked power supply assembly 2 is an optional component. The number of stacked power supply assemblies 2 can be flexibly adjusted according to requirements;

[0054] When a new stacked power supply assembly 2 needs to be stacked, first remove the top operation box assembly 1, and then add a stacked power supply assembly 2 on the top of the topmost stacked power supply assembly 2. During the stacking process of the two stacked power supply assemblies 2 being connected end to end, the plug 203 and the socket 205 cooperate with each other, and the baffle 202 and the socket groove of the socket 205 cooperate with each other to guide the stacking of the two stacked power supply assemblies 2. When the plug 203 is completely inserted into the inner side of the socket groove of the socket 205, the top of the power supply main body 201 is in close contact with the bottom of the socket 205. At this time, the first electrical plug 208 and the second electrical plug 2010 are plugged in.

[0055] During the process of connecting the two superimposed power supply components 2 end to end, the top of the trigger rod 506 first contacts the bottom of the first trigger component 403. The top of the trigger rod 506 is pressed and moves. The top of the trigger rod 506 pushes the driving rod 5032 downward, and the bottom of the trigger rod 506 pushes the center of the first trigger component 403 upward. Among them, the top of the trigger rod 506 is first pressed and moves downward, thereby squeezing the driving rod 5032 to move downward. However, since a driving block 5033 is arranged outside the driving rod 5032, and the driving block 5033 is slidably connected to the inner side of the thread groove 5035, under the limitation of the thread groove 5035, the driving rod 5032 rotates and moves downward along the thread groove 5035, thereby driving the winding roller 5031 to rotate and move downward, winding the bottom of the second connecting wire 502 on the outside of the winding roller 5031 and receiving the cover body 5011 inside the sliding groove, and exposing the first electrical plug connector 208. Subsequently, the contact between the trigger rod 506 and the bottom of the first trigger component 403 pushes the inside of the first trigger component 403 to rotate and rise. The principle is the same as that of the second trigger component 503, so that the second connecting wire 502 is wound around the outside of the top of the first trigger component 403, thereby pulling the lower protective cover 401 back into the power supply main body 201 to expose the second electrical plug connector 2010. When the two superimposed power supply components 2 are completely connected end to end, the top of the annular fixing seat 505 is closely attached to the outer bottom of the first trigger component 403, and the second electrical plug connector 2010 and the first electrical plug connector 208 just complete the plugging action to achieve electrical connection.

[0056] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
