Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a charging pile with a fireproof structure. Background Art

[0002] Charging piles are installed in public buildings, residential parking lots, or charging stations, and can charge various models of electric vehicles at different voltage levels. The input of the charging pile is directly connected to the AC power grid, and the output is equipped with a charging plug for charging electric vehicles. Charging piles can spontaneously combust during use due to problems such as short circuits. Traditional charging piles lack fire retardancy, making it impossible to extinguish fires in the early stages of a fire, leading to further spread of the fire. Patent document 202322843574.2 discloses a fire-resistant charging pile. When the temperature inside the housing rises, a temperature sensor monitors the temperature. The temperature sensor transmits a signal to a controller, which drives a motor. The motor drives the shaft and block to rotate clockwise, separating the block from the baffle. At this point, under the action of gravity, the baffle descends to the bottom of the guide rail. The baffle covers the heat dissipation vent surface, sealing it and preventing air circulation inside and outside the housing. This reduces the oxygen content inside the housing, acts as a flame retardant, and prevents the further spread of the fire. Although this fireproof charging pile can achieve fireproof function, its disadvantages are mainly manifested in that a motor is set outside the shell as an action execution component, which will lead to a significant increase in cost, and secondly, it will lead to a relatively complex structure such as the installation structure and matching structure, and thirdly, the motor is set outside the shell, which has a greater risk of damage and theft. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a charging pile with a simple structure, low cost and a fireproof structure.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows: the charging pile with a fireproof structure includes a shell, a first vent provided on the shell, a shell plate provided outside the first vent, a second vent provided on the shell plate and facing the first vent, and a sliding baffle provided between the shell and the shell plate;

[0005] A limiting groove is provided on one side of the sliding baffle, and a limiting mechanism is provided in the shell. The limiting mechanism has a first position extending along the shell and inserted into the limiting groove to connect the first vent and the second vent, and a second position retracted from the limiting groove to cause the sliding baffle to fall and block the connection between the first vent and the second vent.

[0006] Furthermore, a smoke sensor is provided inside the housing, the smoke sensor is electrically connected to a controller, and the controller is connected to a trigger mechanism, so that the trigger mechanism drives the limiting mechanism to operate.

[0007] Furthermore, the limiting mechanism includes a base plate, a plug connector arranged at one end of the base plate, a connecting plate arranged at the other side of the base plate, and a reset member connected to the base plate. The trigger mechanism pushes the connecting plate to cause the plug connector to extend or retract.

[0008] Furthermore, the trigger mechanism includes a counterweight, a slide groove for controlling the sliding direction of the counterweight, and an electromagnet for controlling the falling or resetting of the counterweight, and the electromagnet is electrically connected to the controller.

[0009] Furthermore, a shell is provided on the outside of the trigger mechanism, and the counterweight block extends out from the lower end after it falls and presses the connecting plate.

[0010] Furthermore, the reset member is a spring.

[0011] Furthermore, the controller is a relay, and the relay is arranged on the inner wall of the shell.

[0012] This fireproof charging pile includes a first vent and a second vent that are spaced apart and facing each other. A sliding baffle is provided between the first and second vents. When the charging pile is in normal use, the sliding baffle, through the cooperation of a limiting groove and a limiting mechanism, keeps the first and second vents in a connected state, which facilitates heat dissipation from the charging pile. If a fire occurs inside, a smoke sensor captures the fire signal and sends a new control signal to a controller. The controller receives the control signal and controls the trigger mechanism to operate, causing the sliding baffle to fall and block the connection between the first and second vents, thus preventing air circulation inside the housing and reducing the oxygen content within the housing, thereby providing a flame retardant effect. Compared to the prior art, this utility model does not require additional components such as a motor, and has a simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0024] like Figure 1-7 As shown, the charging pile with a fireproof structure is characterized by comprising a shell 1, a first vent 2 provided on the shell 1, a shell plate 3 provided outside the first vent 2, a second vent 4 provided on the shell plate 3 and facing the first vent 2, and a sliding baffle 5 provided between the shell 1 and the shell plate 3;

[0025] A limiting groove 51 is provided on one side of the sliding baffle 5, and a limiting mechanism 6 is provided in the shell 1. The limiting mechanism 6 has a first position in which it extends along the shell 1 and is inserted into the limiting groove 51 to connect the first vent 2 and the second vent 4, and a second position in which it retracts from the limiting groove 51 to cause the sliding baffle 5 to fall and block the connection between the first vent 2 and the second vent 4.

[0026] This fireproof charging pile includes a first vent 2 and a second vent 4 that are spaced apart and opposite each other. A sliding baffle 5 is disposed between the first and second vents 2 and 4. During normal use, the sliding baffle 5, through the cooperation of a limiting groove 51 and a limiting mechanism 6, connects the first and second vents 2 and 4, facilitating heat dissipation. If a fire occurs inside the charging pile, a smoke sensor captures a fire signal and sends a new control signal to a controller 73. The controller 73 receives the control signal and controls a trigger mechanism 7 to operate, causing the sliding baffle 5 to fall, blocking the connection between the first and second vents 2 and 4, thereby preventing air circulation inside the housing 1 and reducing the oxygen content within the housing 1, thereby providing a flame retardant effect. Compared to the prior art, this utility model does not require additional components such as a motor, resulting in a simple structure and low cost.

[0027] A smoke sensor is provided inside the housing 1 , and the smoke sensor is electrically connected to the controller 73 , and the controller 73 is connected to the trigger mechanism 7 , so that the trigger mechanism 7 drives the limiting mechanism 6 to operate.

[0028] In this embodiment, the limiting mechanism 6 includes a base plate 61, a plug connector 62 disposed at one end of the base plate 61, a connecting plate 63 disposed at the other side of the base plate 61, and a reset member connected to the base plate 61. The trigger mechanism 7 pushes the connecting plate 63 to cause the plug connector 62 to extend or retract. The reset member is preferably a spring 65.

[0029] The trigger mechanism 7 includes a counterweight 71, a slide for controlling the sliding direction of the counterweight 71, and an electromagnet 72 for controlling the drop or reset of the counterweight 71. The electromagnet 72 is electrically connected to a controller 73. To further enhance the stability of the trigger mechanism 7, a housing is provided on the outside of the trigger mechanism 7. When the counterweight 71 drops, it extends along its lower end and presses against the connecting plate 63.

[0030] In this embodiment, the controller 73 is a relay, which is arranged on the inner wall of the shell 1. After the smoke alarm obtains smoke information, it generates a control signal and sends it to the controller 73. The controller 73 cuts off the power to the electromagnet 72. At this time, the electromagnet 72 loses its magnetism and falls and presses on the connecting plate 63, causing the plug connector 62 to retract from the plug slot. At this time, the sliding baffle 5 falls under the action of gravity and blocks the communication between the first vent 2 and the second vent 4 to achieve a flame retardant effect.

[0031] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
