[0020] Example: Figure 1-Figure 5 As shown, the present invention provides a dedicated battery device for electricity meters, including a support housing 1 installed in the battery compartment of the electricity meter 001, two battery placement compartments are provided in the support housing 1, an installation compartment is provided between the two battery placement compartments, and a partition 13 is provided in the installation compartment. Battery 4 is located in the battery storage compartment; The control unit includes a control board 5 mounted on the top of the partition 13. The control board 5 is wirelessly connected to the energy meter 001 and transmits data. A fixed port 2, which is installed at the bottom of the electricity meter 001 and can be connected to the power line, is used to charge the storage battery 4; the fixed port 2 can be connected to the power line using a wire. Two movable conductive components 3 are located at the bottom of the supporting housing 1, each including an insulating plate 31 and a movable port 33 that penetrates the insulating plate 31. The movable port 33 is plugged into the fixed port 2. A drive unit for moving the active conductive component 3.
[0021] In this embodiment, the control motherboard 5 includes a detection circuit for detecting the power level of the storage battery 4, a power supply circuit for supplying power to the energy meter 001, and a control circuit for controlling the on / off power of the electromagnet 6. By detecting the power level of the storage battery 4, overcharging can be effectively prevented. The control motherboard 5 can communicate with the energy meter 001 and transmit the power data of the storage battery 4 to the energy meter 001, which will then be displayed on the display screen of the energy meter 001.
[0022] Among them, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the drive unit consists of an electromagnet 6 and a transmission assembly 7. The transmission assembly 7 includes a movable rod 73, a fixed plate 74 installed at the bottom of the mounting chamber, and an inverted plate 71 fixed at the bottom of the fixed plate 74. The fixed plate 74 and the inverted plate 71 are both provided with sliding through holes 75 that slide with the movable rod 73, and the electromagnet 6 is installed on the top of the fixed plate 74. The upper end of the movable rod 73 does not protrude from the sliding through hole 75 located on the fixed plate 74. The upper part of the movable rod 73 is embedded with a permanent magnet that can repel the magnetic force generated by the electromagnet 6 after it is energized. The upper part of the movable rod 73 is sleeved and fixed with a limit plate. The movable rod 73 is sleeved with a return spring 72 that is connected to the limit plate and the C-shaped plate 71. The lower end of the movable rod 73 is also provided with a threaded part. In addition to resetting the movable rod 73, the return spring 72 also serves to support the movable rod 73.
[0023] By energizing the electromagnet 6, a magnetic force is generated that repels the permanent magnet. The magnetic force generated by the energized electromagnet 6 drives the movable rod 73 to move outward from the U-shaped plate 71. The limiting plate squeezes the reset spring 72. At the same time, the movable rod 73 drives the insulating plate 31 to move closer to the fixed port 2. The insulating plate 31, along with the movable port 33, is inserted into the fixed port 2, completing the electrical connection between the fixed port 2 and the battery 4. The battery 4 is then charged through the fixed port 2.
[0024] Among them, such as Figure 3 , Figure 8 , Figure 9 and Figure 10 As shown, the movable conductive component 3 also includes a threaded interface 32 fixed to the insulating plate 31 and capable of being screwed to the threaded part, an elastic conductive element, and a conductive bolt 34 for fixing the elastic conductive element. The elastic conductive element consists of two face-to-face C-shaped connecting parts 36, two elastic parts 38, and an arc-shaped connecting part 37 for connecting the C-shaped connecting parts 36 and the elastic parts 38. The C-shaped connecting parts 36 are provided with bolt holes 39 for installing the conductive bolt 34. The elastic parts 38 can be arc-shaped, U-shaped, or other shapes.
[0025] During the process of inserting the insulating plate 31 with the movable port 33 into the fixed port 2, the elastic part 38 of the elastic conductive element opens due to the force. When the movable rod 73 is reset by the elastic force of the reset spring 72, the elastic conductive element also provides the driving force to reset the insulating plate 31. Therefore, the elastic conductive element can not only realize the electrical connection with the battery 4, but also adapt well to the plugging and unplugging requirements of the movable port 33.
[0026] In this embodiment, a copper contact 35 is embedded in the movable port 33, and a copper contact 2 is embedded in the fixed port 2 that can abut against the copper contact 35. Electrical connection is achieved through the mutual contact of the copper contact 35 and the copper contact 2. The conductive bolt 34 is in contact with the copper contact 35 to achieve electrical connection. That is, the conductive bolt 34 and the copper contact 2 are located at the two ends of the copper contact 35, respectively.
[0027] Among them, such as Figure 5 and Figure 6 As shown, the bottom of the storage battery 4 is provided with a charging interface, and the elastic conductive element is electrically connected to the charging interface through a conductive bolt 34. The electrical connection between the charging interface and the elastic conductive element is realized through the conductive bolt 34. The conductive bolt 34 can be made of stainless steel. The conductive bolt 34 is used not only to fix the elastic conductive element, but also to realize the electrical connection.
[0028] Among them, such as Figure 4 As shown, the top of the control motherboard 5 is provided with an adapter port 51 electrically connected to the battery 4 and a power supply interface 52 protruding from the support housing 1. The bottom of the control motherboard 5 is provided with a connection port 53 for electrically connecting to the electromagnet 6. The control motherboard 5 is electrically connected to the electromagnet 6 through the connection port 53. The control motherboard 5 can control the on and off of the electromagnet 6, thereby realizing the automatic charging of the battery 6. The adapter port 51 is used for electrical connection to the battery 4, and the battery 4 supplies power to the control motherboard 5. The power supply interface 52 is a contact interface, and the conductive interface 002 is also a contact interface. The electrical connection is realized by the contact of the conductive contacts.
[0029] Among them, such as Figure 4 As shown, the top of the support housing 1 is provided with a baffle plate, and the baffle plate has an operation port in the middle. The operation port is convenient for connecting the discharge end of the battery 4 to the adapter port 51 with a wire, and is also beneficial for subsequent maintenance.
[0030] Among them, such as Figure 3As shown, the bottom of the support housing 1 is symmetrically provided with support brackets 11, and the bottom of the support brackets 11 is provided with positioning grooves 12. The support brackets 11 support the support housing 1, and the setting of the support brackets 11 also makes it convenient for users to take out the battery device from the battery compartment. The battery device can be quickly positioned by the sliding cooperation between the positioning slide bar 004 and the positioning groove 12.
[0031] Among them, such as Figure 1 , Figure 2 and Figure 11 As shown, the battery compartment of the energy meter 001 is provided with a conductive interface 002, which supplies power to the energy meter 001 by contacting the power supply interface 52. The top wall of the battery compartment of the energy meter 001 is also symmetrically provided with pressure strips 003 for pressing down on the supporting housing 1. The bottom wall of the battery compartment of the energy meter 001 is symmetrically provided with positioning slide strips 004 that slide in cooperation with the positioning slide groove 12. The battery device can be fixed by the pressure strips 003 and the compartment cover 005 without the need for other components, and the structure is very simple.
[0032] Among them, such as Figure 1 and Figure 2 As shown, the battery compartment of the energy meter 001 is provided with a compartment cover 005. One side of the compartment cover 005 is provided with a protrusion that can press down on the supporting housing 1. Both ends of the protrusion are respectively provided with clearance openings for avoiding the pressure strip 003 and the positioning slide strip 004. The clearance openings are provided to accommodate the pressure strip 003 and the positioning slide strip 004, so as to prevent the pressure strip 003 and the positioning slide strip 004 from obstructing the installation of the compartment cover 005.
[0033] During operation, in the event of a power outage, the energy meter 001 is powered by the storage battery 4. When the storage battery 4 is nearly depleted, the control circuit is activated by the control main board 5, energizing the electromagnet 6 to generate a magnetic force that repels the permanent magnet. The magnetic force generated by the energized electromagnet 6 drives the movable rod 73 to move outward from the U-shaped plate 71. The limit plate compresses the return spring 72, and at the same time, the movable rod 73 drives the insulating plate 31 to move closer to the fixed port 2, causing the elastic part 38 to open due to the force. The insulating plate 31, along with the movable port 33, is inserted into the fixed port 2, completing the electrical connection between the fixed port 2 and the storage battery 4. The power line charges the storage battery 4 through the fixed port 2. After the battery is fully charged, the power to the electromagnet 6 is de-energized, and the magnetic force generated by the energized electromagnet 6 disappears. Driven by the elastic force of the return spring 72 and the elastic conductive part, the insulating plate 31, along with the movable port 33, disengages from the fixed port 2, completing one charging cycle.
