When the battery pack 19 needs to be removed for maintenance, the hand wheel 16 is rotated, and the hand wheel 16 rotates to drive the plate 18 to detach from the battery pack 19, and the slider 27 at the bottom of the battery pack 19 can be pulled out along the slide groove 28 provided on the top of the support plate 15, thereby improving the efficiency of removing the battery pack 19 for maintenance.

[0043] In this embodiment, preferably, the slider 27 is a rectangular parallelepiped structure, and the slide groove 28 is a “U”-shaped groove, so that the rectangular slider 27 can slide along the “U”-shaped slide groove 28 more conveniently.

[0044] In this embodiment, preferably, the protection frame 20 is a "U"-shaped structure, a hand wheel 16 is fixed to the other end of the screw rod 14, and the hand wheel 16 is located outside the protection frame 20, so that it is more labor-saving to drive the screw rod 14 to rotate by the hand wheel 16.

[0045] In this embodiment, preferably, a fixing ear 13 is provided on the lower portion of the side surface of the outer frame 12 , and the fixing ear 13 and the horizontal plate 17 are fixed by bolts, which helps to achieve a stable installation of the outer frame 12 , thereby achieving a stable installation of the voltage and current stabilizing circuit board 11 .

[0046] In this embodiment, preferably, a protective door 2 is hinged on the front surface of the box body 8, and a fixed handle 3 is installed on the front surface of the protective door 2. The protective door 2 is used to increase the protection of the internal space of the box body 8. The setting of the fixed handle 3 makes it more convenient to open the protective door 2 through the fixed handle 3.

[0047] In this embodiment, preferably, support feet 9 are installed at the four corners of the bottom of the base 1, and the support feet 9 increase the stability of the base 1. A panel 7 and a switch 4 are installed on the upper front surface of the box 8. The panel 7 and the switch 4 are both connected to the controller 10, the solar panel 6 is connected to the controller 10, the controller 10 is connected to the voltage and current stabilizing circuit board 11, the voltage and current stabilizing circuit board 11 is connected to the battery pack 19, the switch 4 is pressed and the panel 7 is operated to make the circuit device work, and the solar panel 6 supplies power to the battery pack 19 through the controller 10 and the voltage and current stabilizing circuit board 11; a support and guiding mechanism is provided inside the box 8.

[0048] In this embodiment, preferably, the support and guide mechanism includes a movable column 21, a guide rod 22, a fixed column 23, a spring 24, a first fixed ring 25, a second fixed ring 26, and a support member 30. The support member 30 is fixed to the inner side of the box body 8, and the top of the support member 30 is provided with a fixed column 23. One end of the movable column 21 is embedded in the fixed column 23, and the other end extends out of the fixed column 23 and abuts against the controller 10. One end of the spring 24 is connected to the embedded end face of the movable column 21, and the other end is connected to the inner bottom of the fixed column 23. The movable column 21 is provided with a first fixed ring 25, and the bottom of the first fixed ring 25 is provided with a symmetrically distributed guide rod 22. The fixed column A second fixing ring 26 is provided on 23, and a through hole is provided on the surface of the second fixing ring 26 for the guide rod 22 to pass through. When in use, the support member 30 is fixed to the inner side of the box body 8 by bolts. When the movable column 21 is against the controller 10, the movable column 21 is compressed and compresses the spring 24. When the movable column 21 is compressed, the guide rod 22 at the bottom of the first fixing ring 25 is inserted along the through hole provided on the surface of the second fixing ring 26, so as to increase the guidance of the movable column 21 when it moves. The spring 24 is compressed and reset, and the reset spring 24 drives the movable column 21 to press against the controller 10, so as to further increase the support for the controller 10, so that the controller 10 is installed in the box body 8 more firmly.

[0049] In this embodiment, the voltage and current stabilizing circuit board 11 is connected in series with the battery pack 19 via a connecting structure 54. The connecting structure 54 is installed in the box body 8 and includes a shell 31 and a plug rod 32 plugged into the shell 31. One end of the plug rod 32 is located in the shell 31 and is installed with a plug sheet 34 and a push rod 39. The other end of the plug rod 32 is installed with an end cover 33. The shell 31 is installed with a plug slot 35 and two contacts that are plugged with the plug sheet 34. The end of the plug sheet 34 is installed with a first resistor 36. The two contacts include a first contact 37 and a second contact 38 that can contact the first contact 37. The first contact 37 is connected in series with the plug sheet 34, and the second contact 38 is connected in series with the first resistor 36.

[0050] like Figures 5 and 6 As shown, in the initial state, the plug 34 and the first resistor 36 are not inserted into the insertion slot 35, and the plug 34 and the first resistor 36 are not directly connected in series, but are connected in series through two contacts, specifically: the second contact 38 is in contact with the second contact 38, the first contact 37 is connected in series with the plug 34, the second contact 38 is connected in series with the first resistor 36, and the plug 34 is connected in series with the voltage and current stabilizing circuit board 11, and the insertion slot 35 is connected in series with the battery pack 19. When the end cover 33 is pressed, the plug 34 drives the first resistor 36 to be inserted into the insertion slot 35. During the pressing process, the plug rod 32 drives the push rod 39 to move downward, and the end of the push rod 39 can contact one of the two contacts and push it away. In this embodiment, taking the second contact 38 as an example, the push rod 39 pushes the second contact 38 to make it out of contact with the first contact 37, thereby realizing the disconnection of the series connection between the plug 34 and the first resistor 36 and becoming an open circuit state. Since the plug 34 is inserted into the plug slot 35 , a series connection is achieved, so that the solar panel 6 can supply power to the battery pack 19 through the controller 10 and then through the voltage and current stabilizing circuit board 11 .

[0051] When the battery pack 19 is fully charged, it is necessary to take the fully charged battery pack 19 out of the housing 8 and then replace the battery pack 19 to be charged. In this way, the circuit device needs to be shut down as a whole first, which can be achieved through the switch 4. Then, in non-emergency situations, cutting off the power through the switch 4 will affect the operation of the entire device. For example, when there are multiple battery packs 19, when one battery pack 19 is not fully charged, it will affect the charging of the group. For example, it is necessary to conduct live inspections on the battery packs 19 of the entire device or the inside of the housing 8 for leakage or other live parts. If it is shut down, it will also cause an impact. Therefore, after one of the battery packs 19 is fully charged, the connection structure 54 can be used to realize the connection and disconnection between the voltage and current stabilizing circuit board 11 and the battery pack 19.

[0052] In the initial state, the plug 34 and the first resistor 36 are not inserted into the plug slot 35. At this time, the voltage and current stabilizing circuit board 11 and the battery pack 19 are not connected, so no current flows. After the plug 34 is inserted into the plug slot 35, it is powered and current begins to flow. Since the connection between the plug 34 and the plug slot 35 can connect or disconnect the battery pack 19 from the charging circuit when the solar panel 6 is working and maintaining power generation, and the plug-in and unplugging between the plug 34 and the plug slot 35 is hot plugging, during which high temperature and electric sparks will be generated, which will damage the electronic components in the device and even cause harm to the operator. In this embodiment, by setting the first resistor 36 to increase the resistance of the plug 34, the current can be reduced during the plug-in and unplugging process, which will avoid the generation of high temperature and electric sparks. Therefore, the operation is safer, and after insertion, the first resistor 36 and the plug 34 are disconnected in series, so that the current can be maximized and approximately equal to the power supply voltage, thus ensuring that the solar panel 6 charges the battery pack 19 stably.

[0053] like Figures 6 to 8 As shown, when the inserting piece 34 is gradually inserted into the inserting slot 35 from the initial state, the push rod 39 does not contact the second contact 38 when the inserting piece 34 is just inserted into the inserting slot 35, and the push rod 39 is pushed downward when the inserting piece 34 is further inserted, so that the push rod 39 is out of contact with the first contact 37. In order to make the first contact 37 and the second contact 38 contact again after the inserting piece 34 is reset, the second spring 54 can be provided to rebound the second contact 38.

[0054] In this embodiment, an outer test rod 40 is provided at the bottom of the plug 32, and an inner test rod 41 with a third spring 42 is inserted into the inner cavity of the outer test rod 40. A second resistor 43, a neon tube 44, a fourth spring 45 and a hand touch electrode 46 connected in sequence are provided in the inner cavity of the plug 32. The second resistor 43 is electrically connected to the outer test rod 40, and the hand touch electrode 46 is fixed on the inner side of the end cover 33. A buzzer 47 and an L-shaped rod 49 are also provided on the outer wall of the plug 32. The buzzer 47 is electrically connected to the hand touch electrode 46, the outer wall of the plug-in slot 35 is electrically connected to the external test rod 40, an insulating block 48 is arranged between the external test rod 40 and the plug-in rod 32, a T-shaped rod 51 is penetrated through the L-shaped rod 49, the outer wall of the plug-in rod 32 also has a protrusion 50 with a rounded upper portion and a flat angle at the bottom, a fifth spring 52 is arranged between the T-shaped rod 51 and the outer wall of the L-shaped rod 49, and the end of the T-shaped rod 51 is a hook head 53 that matches the protrusion 50.

[0055] like Figure 6 and Figure 8As shown, in this embodiment, two protrusions 50 are provided, that is, there are two gears. In the initial state, the hook head 53 is hooked and matched with the protrusion 50 at the upper part, which is the first gear. When pressing down, the hook head 53 moves accordingly until it is hooked and matched with the protrusion 50 at the lower part, which is the second gear. The insertion rod 32 can be reset by simply pulling the T-shaped rod 51 outward to disengage the hook head 53 from the protrusion 50. The upper part of the protrusion 50 is rounded to facilitate the hook head 53 to be easily pressed down, and the bottom is flat angled so that when the end cover 33 is stopped from being pressed down, the hook head 53 can hook the protrusion 50 after releasing the hand without being unhooked.

[0056] In this embodiment, in the initial state, when the battery pack 19 is connected to the plug slot 35, the outer wall of the plug slot 35 is in an insulating state. Once the neon tube 44 and / or the buzzer 47 emit light and / or sound an alarm, it means that the circuit is turned on, indicating that current has passed, indicating that there is leakage, reminding to pay attention to safety, and need to be checked. The inner test rod 41 and the hole reserved at the bottom of the shell 31 are not shown in the figure. If there is no light and / or sound alarm in the initial state, when the end cover 33 is pressed, the inner test rod 41 can be extended to the outside of the shell 31 and contact the inner wall of the box 8. At this time, if there is light and / or sound alarm, it means that there is leakage on the inner wall of the box 8, which needs to be checked. Through the neon tube and the buzzer, some low-voltage circuits can still be checked, thereby improving the accuracy of detection.

[0057] In this embodiment, the size of the first resistor 36 and the second resistor 43 can be selected according to the actual situation. For example, the first resistor 36 can be selected according to the voltage flow of solar energy. For example, if it is 220V, the resistance should be shared to a human safety voltage below 36V. The second resistor 43, such as 1 to 3 megohms. Unless necessary, the connection structure 54 components should be mainly made of insulating materials, such as the housing 31, the plug 32, etc., which are insulated, and conductive materials can be used for series connection, electrical connection, etc.

[0058] A method for using a circuit device powered by an energy storage battery pack comprises the following steps:

[0059] Step 1: Open the protective door 2 through the fixing handle 3, pick up the outer frame 12, and fix the fixing ears 13 on the side surface of the outer frame 12 to the horizontal plate 17 through bolts, so that the voltage and current stabilizing circuit board 11 is installed firmly;

[0060] Step 2: Fix the support plate 15 to the inner bottom of the box body 8; pick up the battery pack 19, and insert the slider 27 at the bottom of the battery pack 19 into the slide groove 28 provided at the top of the support plate 15. After the battery pack 19 is inserted, turn the hand wheel 16, and the rotation of the hand wheel 16 drives the plate 18 to move toward the inner side of the protective frame 20 until the plate 18 is firmly pressed against the battery pack 19, thereby realizing a quick and stable installation of the battery pack 19;

[0061] Step 3: Connect the panel 7 and the switch 4 to the controller 10, connect the solar panel 6 to the controller 10, connect the controller 10 to the voltage and current stabilizing circuit board 11, and connect the voltage and current stabilizing circuit board 11 to the battery pack 19;

[0062] Step 4: Close the protective door 2 securely, turn on the power, press the switch 4, and operate the panel 7 to operate the circuit device. The solar panel 6 supplies power to the battery pack 19 through the controller 10 and the voltage and current stabilizing circuit board 11.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
