Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a new energy charging device with a circuit breaker. Background Art

[0002] New energy charging devices usually refer to charging piles, which are energy replenishment devices for new energy vehicles. When in use, it is usually necessary to set up a charging pile. After parking the new energy vehicle on the charging pile, the charging plug is inserted into the new energy vehicle in the same way as refueling. After connection, the same principle is used as mobile phones and other electrical appliances for transmission. Since overload and other situations are prone to occur during the transmission process, a circuit breaker switch is usually set to protect the circuit.

[0003] Since charging piles need to be deployed in various locations, such as basements, outdoors, and private garages, when the charging piles are set up in basements, underground garages, etc., dust and other substances are easily accumulated on the charging piles due to being underground for a long time, which can easily cause malfunctions in the switching circuits, resulting in tripping and other situations that affect the normal use of the charging piles. Summary of the invention

[0004] In order to solve the problem that when charging piles are set in basements, underground garages and other locations in the prior art, dust and the like are easily accumulated on the charging piles due to being underground for a long time, which can easily cause malfunctions of the switching circuits, thereby causing tripping and other situations that affect the normal use of the charging piles, the present application provides a circuit breaker for a new energy charging device, and the specific solution is as follows.

[0006] A shielding cover is provided on the switch body corresponding to the wrench, and the shielding cover completely shields the upper and lower sides of the switch body where the wires are provided and the side wall where the wrench is provided, and a vacuum cleaner and a collection bag are provided in the shielding cover, and the collection bag and the vacuum cleaner are detachably connected, and the vacuum cleaner is used to extract the debris at the circuit breaker into the collection bag, and a transparent window is provided at the position of the shielding cover corresponding to the collection bag, through which the state of the collection bag can be observed, and an independent power supply is provided on the switch body corresponding to the vacuum cleaner;

[0007] The vacuum cleaner is provided with a micro switch, and when the wrench closes the switch body, the wrench contacts the micro switch to start the vacuum cleaner.

[0008] By adopting the above technical solution, a shielding cover is set to shield the switch body, which can reduce the situation where dust enters the switch body. At the same time, a vacuum cleaner is set to suck out dust from the switch body. Since the vacuum cleaner needs to be started by a microswitch, an independent power supply can power the vacuum cleaner after installation. When a tripping occurs, it is judged that dust may be present inside. The wrench can move toward the microswitch, and the microswitch can start the vacuum cleaner to suck out the dust, thereby reducing the situation where dust enters the switch body through the gap of the wrench and causes an impact. The transparent window can timely observe the condition of the collection bag, which is convenient for timely replacement of the collection bag.

[0010] By adopting the above technical solution, a socket is provided, and a plug is provided on the vacuum cleaner. The connection between the plug and the socket can further fix the stability of the connection between the shielding cover and the switch body, thereby reducing the situation where the shielding cover falls off.

[0013] Optionally, the shielding cover is provided with a sliding groove corresponding to the plug, and the plug is slidably connected in the sliding groove.

During installation, the reverse thrust of the spring can block the installation, and then the position of the plug is fixed by the snap-fitting part. When the plug moves toward the snap-fitting part, the locking part can also move upward. Since the snap-fitting part locks the position of the plug, the plug no longer moves.

[0035] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0036] A circuit breaker for a new energy charging device, such as Figure 1 and Figure 2As shown, it includes a switch body 1, the upper and lower sides of the switch body 1 are used to connect with the wires, and a wrench 11 is provided on the side wall of the switch body 1, and the wrench 11 is used to control the on and off of the circuit. In specific implementation, the upper and lower sides of the switch body 1 are connected to the wires to access the circuit of the charging pile. Its working principle is to use springs and other existing technologies to control the on and off. When an arc is generated, the circuit will be disconnected, and the wrench 11 can be moved to complete the circuit breaking. When reconnecting, just pull the wrench 11.

[0037] like Figure 1 and Figure 2 As shown, a shielding cover 2 is provided on the switch body 1 corresponding to the wrench 11, and the shielding cover 2 completely shields the upper and lower sides of the switch body 1 where the wires are provided and the side wall where the wrench 11 is provided. A vacuum cleaner 3 and a collection bag 31 are provided in the shielding cover 2, and the collection bag 31 is detachably connected to the vacuum cleaner 3. The vacuum cleaner 3 is used to extract debris at the circuit breaker into the collection bag 31. A transparent window 23 is fixedly provided at the position of the shielding cover 2 corresponding to the collection bag 31, and the state of the collection bag 31 can be observed through the transparent window 23. An independent power supply is provided on the switch body 1 corresponding to the vacuum cleaner 3. A micro switch is provided on the vacuum cleaner 3. When the wrench 11 closes the switch body 1, the wrench 11 contacts the micro switch to start the vacuum cleaner 3. In specific implementation, the transparent window 23 can be made of plastic material, and a hole 14 for discharging dust is opened on the switch body 1. An independent power supply is used to power the vacuum cleaner 3. When an abnormality occurs in the circuit breaker, the circuit breaker can perform circuit breaking protection. During the protection process, the vacuum cleaner 3 is started to suck out the dust in the circuit breaker, thereby reducing the impact of dust on the switch body 1. The state of the collection bag 31 can be observed through the transparent window 23, and the collection bag 31 can be replaced in time when too much dust is collected.

[0038] like Figure 1 and Figure 2 As shown, the independent power source is also provided with a socket 12, and the vacuum cleaner 3 is provided with a plug 32 corresponding to the socket 12, and the plug 32 is connected to the vacuum cleaner 3 through a wire, and when the shielding cover 2 is connected to the switch body 1, the plug 32 and the socket 12 are connected to each other. In specific implementation, the plug 32 can be connected to the socket 12, and then power can be supplied. During the power supply process, the connection between the plug 32 and the socket 12 can also fix the position of the shielding cover 2, thereby assisting in fixing the shielding cover 2.

[0039] like Figure 1 and Figure 2As shown, the socket 12 is arranged on the upper side of the switch body 1, the plug 32 is arranged at the position of the top of the shielding cover 2 corresponding to the socket 12, and a groove 13 for the plug 32 to be inserted is provided on the switch body 1 corresponding to the socket 12, and a locking member 4 is arranged at the bottom of the shielding cover 2, and the locking member 4 can clamp the switch body 1 in cooperation with the plug 32. In specific implementation, after the shielding cover 2 is installed, the plug 32 and the locking member 4 can clamp the switch body 1 in a claw-like manner, so that the shielding cover 2 is fixedly installed on the switch body 1, and the matching fixation is achieved.

[0040] like Figure 1 and Figure 2 As shown, the shielding cover 2 is provided with a slide groove 22 corresponding to the plug 32, and the plug 32 is slidably connected in the slide groove 22. A clamping piece 222 is provided at the top of the slide groove 22 corresponding to the plug 32, and the clamping piece 222 is detachably connected to the plug 32. The plug 32 is linked to the locking piece 4. When the plug 32 moves upward, the locking piece 4 moves upward to clamp the switch body 1. A push spring 221 is also provided in the slide groove 22, and the push spring 221 is used to push the plug 32 to move toward the end away from the shielding cover 2. One end of the clamping piece 222 extends into the shielding cover 2, and the other end of the clamping piece 222 extends out of the shielding cover 2 and is provided for the user to disassemble and assemble. In specific implementation, the clamping part 222 can be a bolt, which is threadedly connected to the shielding cover 2 after tightening, and then threadedly connected to the plug 32, so that the position of the plug 32 can be fixed. The plug 32 can also be fixed by using a pin on the side wall. When the plug 32 is connected to the socket 12, the plug 32 can drive the locking part 4 to move upward, thereby clamping the shielding cover 2 on the switch body 1. When the plug 32 is removed, it can be conveniently removed due to the presence of the push spring 221.

[0041] like Figure 1 and Figure 2 As shown, a connecting rod 41 is provided between the plug 32 and the locking member 4, one end of the connecting rod 41 is fixedly connected to the shielding cover 2, and the other end of the connecting rod 41 is fixedly connected to the locking member 4. An embedding groove 13 is provided on the switch body 1 corresponding to the locking member 4, and the locking member 4 is used to embed in the embedding groove 13. In specific implementation, the locking member 4 is provided in a block or columnar shape, which can be inserted and embedded in the embedding groove 13 to form interference and reduce the situation of falling off. When the plug 32 moves up and down, the connecting rod 41 can drive the locking member 4 to move up and down. When the plug 32 is pushed upward in the slide groove 22, the connecting rod 41 can also drive the locking member 4 to move upward and embed in the corresponding embedding groove 13. Therefore, when the shielding cover 2 is installed, the plug 32 is pushed toward the clamping member 222 by pressing after connection. At this time, the locking member 4 can enter the embedding groove 13 for cooperation, thereby completing the installation of the shielding cover 2, thereby further improving the convenience of installation.

[0042] like Figure 1 and Figure 2 As shown, the shielding cover 2 is also provided with a push rod 5, which is slidably connected with the shielding cover 2. The push rod 5 is arranged at the position corresponding to the wrench 11 and is used to push the wrench 11. The push rod 5 is also provided with a reset spring 51, which has the function of pulling the push rod 5 to move in a direction away from the wrench 11. In specific implementation, the bottom of the push rod 5 is provided with a docking groove 52 corresponding to the shape of the wrench 11, and the wrench 11 can be embedded in the docking groove 52. When a trip occurs, the shielding cover 2 does not need to be removed, and the wrench 11 can be re-circuited. When the circuit cannot be re-circuited, the push rod 5 can also feel the reverse thrust, which further reduces the situation where dust enters the interior of the shielding cover 2. After the adjustment is completed, the push rod 5 can be pushed by the reset spring 51 to return to its original position, reducing the tripping of the wrench 11 caused by the gravity.

[0043] Working principle: When installing the shielding cover 2, the plug 32 and the locking piece 4 are matched during installation. When the plug 32 is connected to the socket 12, the locking piece 4 can be pressed into the groove 13, and then the position of the plug 32 is fixed by the snap-fit ​​piece 222, so that the shielding cover 2 is completely installed on the switch body 1. After the installation is completed, the microswitch on the vacuum cleaner 3 in the shielding cover 2 can detect the wrench 11. According to the microswitch, whether the wrench 11 is tripped or not, there may be dust affecting the switch body 1. When it trips, the vacuum cleaner 3 can be started to suck the inside of the switch body 1, thereby reducing the impact of dust on the switch body 1.

[0044] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
