Technical Field

[0001] The present invention relates to the technical field of charging stacks, and in particular to a matrix charging stack. Background Art

[0002] Matrix charging piles are usually composed of multiple charging modules, which are arranged in the form of a matrix. Each charging module can work independently or be combined as needed to provide charging services for electric vehicles of different types and power requirements. According to the battery capacity, charging requirements and power supply capacity of the electric vehicle, the matrix charging pile can dynamically allocate charging power. The charging pile is equipped with an advanced intelligent control system that can monitor various parameters during the charging process in real time, such as voltage, current, temperature, etc.

[0003] In the existing matrix charging stack, the charging modules may short-circuit or overheat during operation, which can easily lead to spontaneous combustion of the circuit. Most of the existing matrix charging stacks directly stack the charging modules together. When one of the charging modules overheats or short-circuits, spontaneous combustion occurs, causing overall damage to the device and maximizing the loss of the device. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. If a short circuit occurs in the device, the charging module will heat up, causing the hot melt rod to melt. The first connecting block forms an elastic structure with the second connecting block through a spring. The elastic structure pulls the closed upper cover downward, so that the holes on the closed side panel are misaligned with the holes on the protective shell. This will cause the protective shell, the closed side panel and the closed upper cover to form a closed space, which will seal the inside of the device to prevent the arc caused by the short circuit from leaking out and damaging the surrounding charging modules. At the same time, the closed state can isolate the external air from the charging module, so that the charging module has no combustion conditions and cannot burn, thereby avoiding the spread of damage to the equipment.

[0017] 2. When the closed upper cover of the device moves downward, the piston rod will squeeze the air inside the first piston sleeve, thereby squeezing the air inside the first piston sleeve into the second piston sleeve, so that the piston plate moves downward, pushing the telescopic rod, thereby moving the insulating plate downward, and separating the power output wire or power supply wire installed on the mounting ring from the charging module, thereby completely isolating the charging module. At the same time, the insulating plate insulates and blocks the connection of the charging module to prevent the generated arc from leaking and affecting the operation of the entire device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 5The present invention provides a technical solution: comprising a shell component 1 and a closing component 5, wherein a protective component 4 is installed inside the shell component 1, the closing component 5 is located above the protective component 4, and the closing component 5 comprises a closed upper cover 501, a closed side plate 502, a first connecting block 503, a spring 504 and a second connecting block 505, the closed side plates 502 are installed on the left and right sides of the lower end of the closed upper cover 501, and the first connecting block 503 is connected to the front and rear sides of the closed upper cover 501, the lower end of the first connecting block 503 is connected to the spring 504, and the lower end of the spring 504 is connected to the second connecting block 505;

[0029] If a short circuit occurs, the charging module 801 will heat up, causing the hot melt rod 802 to melt. The first connecting block 503 forms an elastic structure with the second connecting block 505 through the spring 504. The elastic structure pulls the closed upper cover 501 downward, so that the holes on the closed side panel 502 are misaligned with the holes on the protective shell 401. This will cause the protective shell 401, the closed side panel 502 and the closed upper cover 501 to form a closed space, which will seal the inside of the device to prevent the arc caused by the short circuit from leaking out and damaging the surrounding charging modules 801. At the same time, in the closed state, the external air can be isolated from the charging module 801, so that the charging module 801 has no combustion conditions and cannot burn, thereby avoiding the spread of damage to the equipment.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a split mounting plate 2 is provided at the lower end of the protective component 4, and a selection component 3 is connected to the front end of the protective component 4, a charging component 8 is installed inside the protective component 4, and pneumatic components 6 are provided on the left and right sides of the closing component 5, and a cutting component 7 is connected to the lower end of the pneumatic component 6.

[0031] like Figure 1 As shown, the housing assembly 1 includes a housing 101, a connection socket 102, a heat dissipation fan 103 and a power supply line 104, and the connection socket 102 is installed at the front end of the housing 101, the heat dissipation fan 103 is installed on the left side of the housing 101, and the power supply line 104 is installed at the rear end of the housing 101;

[0032] The connection socket 102 is connected to the charging line to power the external charging device. The power supply line 104 can connect the device to the circuit to make the device work. The cooling fan 103 can cool the device to keep the device working.

[0033] like Figure 3As shown, the selection component 3 includes a channel selection circuit board 301 and an output power conductor 302 , and the rear end of the channel selection circuit board 301 is connected to the output power conductor 302 .

[0034] like Figure 4 As shown, the protection component 4 includes a protection shell 401 and a first permanent magnet 402, and the first permanent magnet 402 is embedded on the front and rear sides of the protection shell 401;

[0035] The protective shell 401, the closed upper cover 501 and the closed side plate 502 are insulated with ceramic materials. At the same time, the ceramic materials will not affect the heat dissipation effect. In this way, even when the protective shell 401 is in a closed state, the heat dissipation effect of the heat dissipation fan 103 can still be effective for the overheated charging module 801.

[0036] like Figure 7 As shown, the pneumatic assembly 6 includes a piston rod 601, a first piston sleeve 602, a second piston sleeve 603, a piston plate 604 and a telescopic rod 605, and the lower end of the piston rod 601 is externally connected to the first piston sleeve 602, the lower end of the first piston sleeve 602 is connected to the second piston sleeve 603, and the piston plate 604 is installed inside the second piston sleeve 603, and the lower end of the piston plate 604 is connected to the telescopic rod 605;

[0037] When the closed upper cover 501 moves downward, the piston rod 601 will squeeze the air inside the first piston sleeve 602, thereby squeezing the air inside the first piston sleeve 602 into the second piston sleeve 603, so that the piston plate 604 moves downward, pushing the telescopic rod 605, so that the insulating plate 701 moves downward, and the power output wire 302 or the power supply wire 104 installed on the mounting ring 703 is separated from the charging module 801, thereby completely isolating the charging module 801. At the same time, the insulating plate 701 insulates and blocks the connection of the charging module 801 to prevent the generated arc from leaking and affecting the operation of the entire device.

[0038] like Figure 7 As shown, the cutting assembly 7 includes an insulating plate 701 and a second permanent magnet 702, and the second permanent magnet 702 is inlaid on the left and right sides of the insulating plate 701, and the insulating plate 701 also includes a mounting ring 703 and a third permanent magnet 704, and the lower end of the insulating plate 701 is connected to the mounting ring 703, and the left and right sides of the mounting ring 703 are connected to the third permanent magnet 704;

[0039] The third permanent magnet 704 and the second permanent magnet 702 can both adsorb the first permanent magnet 402 to position the mounting ring 703 and the insulating plate 701 respectively.

[0040] like Figure 8 As shown, the charging assembly 8 includes a charging module 801 and a hot melt rod 802 , and the hot melt rod 802 is installed on the upper end of the charging module 801 .

[0041] Working principle: First, connect the device to the circuit through the power supply line 104, and then power the cooling fan 103 through another circuit, so that the cooling fan 103 works to dissipate heat inside the device. When in use, the user can connect the charging line through the connection socket 102 for use. When in use, the charging module 801 will be automatically selected through the channel selection circuit board 301, and the required charging power will be allocated autonomously, so that the electricity at the power supply line 104 is transmitted to the channel selection circuit board 301 through the charging module 801 and the power output wire 302, and then the electricity is transmitted to the connection socket 102. The charging cable is thus powered, allowing the user to work normally. When the device is working, if one of the charging modules 801 is short-circuited or overheated, the temperature inside the protective shell 401 will rise rapidly, causing the hot melt rod 802 to melt. At this time, the closed upper cover 501 will lose the support of the hot melt rod 802, and the first connecting block 503 will pull the closed upper cover 501 through the elastic structure between the spring 504 and the second connecting block 505, so that the closed upper cover 501 is pressed downward, and the closed upper cover 501 will close the top of the protective shell 401, and at the same time, the closed side plate 502 will be The holes will align with the holes on the side wall of the protective shell 401, so that the closed side plate 502 blocks the side wall of the protective shell 401. In this way, the protective shell 401, the closed upper cover 501 and the closed side plate 502 will form a closed environment, thereby preventing the arc caused by the short circuit of the charging module 801 from leaking out. At the same time, the closed environment can also prevent air from entering the protective shell 401, so that the charging module 801 loses the conditions required for combustion. In this way, it can prevent the charging module 801 from burning when it is overheated. When the closed upper cover 501 moves downward, the piston rod 601 squeezes the air inside the first piston sleeve 602 , thereby squeezing the air inside the first piston sleeve 602 into the second piston sleeve 603, so that the piston plate 604 moves downward, pushing the telescopic rod 605, so that the insulating plate 701 moves downward, and the power outgoing wire 302 or the power supply wire 104 installed on the mounting ring 703 is separated from the charging module 801, thereby completely isolating the charging module 801. At the same time, the insulating plate 701 insulates and seals the connection of the charging module 801 to prevent the generated arc from leaking, so that the damaged charging module 801 is completely isolated from the external environment of the protective shell 401, which can reduce losses and prevent losses from expanding and affecting the entire device.

[0042] 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.
