Technical Field
[0001] This invention relates to the field of charging equipment technology, specifically to a controllable louver for a charging pile. Background Technology
[0002] With the continuous development of modern society, human activities have increasingly damaged nature, leading to the extinction of many species and irreversible environmental damage. Therefore, in order to protect the environment and ourselves, the country advocates green development and energy conservation and emission reduction in all sectors. The automotive industry is also making changes. Electric vehicles are products produced by the automotive industry in response to energy conservation and emission reduction. Electric vehicles typically use on-board power to drive the motor to rotate the wheels. Because they use electricity to drive the vehicle, electric vehicles have a lower environmental impact than traditional fuel vehicles, thus having great development potential. Electric vehicle power needs to be charged in time after use. Charging piles are institutions that can charge electric vehicle power. They can be installed on the ground or on the wall, similar to the gas pumps in gas stations. However, DC charging piles used for electric vehicle charging have high power and generate a lot of heat during charging, resulting in high heat dissipation capacity. Nowadays, most charging piles have air inlets and outlets to allow air to circulate and dissipate heat, that is, they use air cooling. However, using large ventilation openings will make it easier for dust and rainwater to enter the charging pile, affecting the function and safety of the charging pile. Therefore, the air inlets and outlets of existing charging piles are basically protected by louvers.
[0003] However, the existing charging pile louvers have the following problems;
[0004] Because the louvers of the charging pile are fixed and cannot be opened, closed, or controlled, although the air inlet of the charging pile is equipped with filter cotton, it cannot completely prevent dust. Moreover, most of the air outlets have no dustproof measures. When the charging pile stops working, dust can enter the charging pile through the louvers. Although the charging pile is waterproof under normal rainy weather, some rainwater can still enter the charging pile through the louvers during typhoons and heavy rain. Therefore, it is necessary to control the louvers on the charging pile to improve the protection of the air inlet and outlet of the charging pile. However, the existing charging pile louvers cannot be automatically controlled and adjusted, resulting in insufficient protection of the air inlet and outlet of the charging pile. This makes it easy for dust and rainwater during typhoons and heavy rain to enter the charging pile and cause damage.
[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing charging pile louvers. Summary of the Invention
[0006] The purpose of this invention is to provide a controllable louver for a charging pile, in order to solve the problem mentioned in the background art that the existing charging pile louvers cannot be automatically controlled and adjusted, resulting in insufficient protection of the air inlet and outlet of the charging pile, which easily allows dust and rainwater during typhoons and rainstorms to enter the charging pile and damage it.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a controllable louver for a charging pile, comprising a cover plate, an air inlet inside the cover plate, and a motor mounting bracket fixedly connected to the upper side of the cover plate. The inner wall of the motor mounting bracket is connected to the upper end of a linear motor via motor fixing screws. A micro switch is installed on the cover plate on the side of the motor mounting bracket. A louver housing is fixedly installed on the side of the cover plate near the motor mounting bracket. Vertical supports are provided on both sides of the louver housing. A connecting rod is provided on the side of the louver housing, and the connecting rod is located between the louver housing and the vertical supports. A louver blade is embedded inside the louver housing, and an upper fixing lug is fixedly connected to the end of the louver blade. The upper fixing ear has an upper fixing hole inside, and a lower fixing ear is fixedly installed on the louver end of the upper fixing ear. The lower fixing ear also has a lower fixing hole inside. An outer positioning pin is provided on one side of the connecting rod, and an inner positioning pin is installed on the other side of the connecting rod. A straight groove is provided inside the vertical bracket, and a crossbeam is fixedly connected to the upper end of the vertical bracket. A movable beam is attached to the inner wall of the upper end of the crossbeam, and the end of the movable beam is connected to the upper end of the connecting shaft through a connecting shaft fixing nut. The lower end of the connecting shaft is fixedly connected to the upper end of the drive rod. A guide body is provided on the outer side of the vertical bracket, and a guide fixing nut is installed at the end of the guide body. A baffle is fixedly installed on the upper end of the movable beam.
[0008] Preferably, the lower end of the linear motor is provided with a motor shaft, and the lower end of the motor shaft is fixedly connected to the upper end of the movable beam.
[0009] Preferably, the lower inner wall of the crossbeam is provided with a pin, the outer wall of the pin is provided with a spring, and the upper end of the pin is provided with a connecting shaft body, and the upper end of the spring is connected to the connecting shaft body.
[0010] Preferably, the louver housing has a ventilation opening on the side away from the cover plate, and the inner wall of the side of the louver housing is fixedly connected with side positioning pins at equal intervals, and the inner wall of the side of the louver housing on the side of the side positioning pin has an arc-shaped groove.
[0011] Preferably, the guide bodies on the sides of the vertical support are distributed in parallel, and the guide bodies and the drive rods are movably connected.
[0012] Preferably, the outer positioning pin and the straight slot are slidably connected, and the outer positioning pin is connected to the drive rod.
[0013] Preferably, the inner positioning pin and the arc-shaped groove are slidably connected, and the inner positioning pin and the upper fixing hole are rotatably connected.
[0014] Compared with the prior art, the beneficial effects of the present invention are: the controllable louvers of the charging pile can be closed and opened. When opened, the louvers provide sufficient air intake to ensure heat dissipation. When closed, the louvers prevent dust and rainwater from entering the charging pile. At the same time, the controllable louvers of the charging pile can automatically control the louvers when the charging pile needs to work, avoiding manual operation by personnel.
[0015] 1. By moving the drive rod, the outer positioning pin drives the connecting rod to move, which in turn drives the inner positioning pin to move along the arc-shaped groove. This allows the inner positioning pin to open the louvers through the upper fixing hole, ensuring the heat dissipation of the charging pile. Then, by moving the drive rod in the opposite direction, the louvers close, protecting the charging pile.
[0016] 2. The linear motor controls the movement of the motor shaft, causing the motor shaft to move and thus the movable beam moves through the connecting shaft to drive the drive rod. The drive rod automatically opens or closes the louvers, thus eliminating the need for manual operation and improving the ease of use of the device. Attached Figure Description

[0036] Working principle: When using the controllable louvers of this charging station, firstly as follows... Figure 1-4 As shown, the cover plate 1 is installed on the charging pile, and the louver housing 9 is located inside the charging pile. The drive rod 11 is connected to the connecting rod 15, and the connecting rod 15 is connected to the louver blade 16. The lower fixing ear 1603 of the louver blade 16 has a lower fixing hole 1604, which is fixed to the louver housing 9 by the side positioning pin 902 on the louver housing 9. The side positioning pin 902 is the fixing point of the louver blade 16. Figure 1 and Figure 3-9As shown, when the charging pile starts working, the charging pile control system sends a signal to start the linear motor 4, causing the motor shaft 401 to move downwards. The drive rod 11 moves downwards linearly in sync, the outer positioning pin 1501 of the connecting rod 15 moves downwards linearly, and the inner positioning pin 1502 is constrained by the arc-shaped slot 901. It moves backwards along the arc with the side positioning pin 902 of the louver housing 9 as the center. The lower fixing ear 1603 of the louver 16 can only rotate but cannot move. At this time, the louver 16 flips backwards and opens to facilitate heat dissipation of the charging pile. The micro switch 18 is also equipped with... Positioned above the movable beam 5, the baffle 19 has two contacts, one above the other. The lower end of the baffle 19 is fixed to the movable beam 5, and the upper end is located between the two contacts of the microswitch 18. The baffle 19 moves with the up-and-down movement of the motor shaft 401, and moves synchronously with the motor shaft 401. When the upper end of the baffle 19 moves down and touches the lower contact of the microswitch 18, a signal is fed back to the charging pile control system. The charging pile control system sends a stop signal to the linear motor 4, and the drive mechanism stops. At this time, the louver 16 is in the open state, allowing air to enter and exit. Figure 1 and Figure 4-9 As shown, when the charging pile stops working, the charging pile control system sends a signal to start the linear motor, causing the motor shaft 401 to move upward. The drive rod 11 moves upward in a straight line in sync, the outer positioning pin 1501 of the connecting rod 15 moves upward in a straight line, and the inner positioning pin 1502 is constrained by the arc-shaped slot 901. It moves forward along the arc with the side positioning pin 902 of the louver shell 9 as the center. The lower fixed ear 1603 of the louver 16 can only rotate and cannot move. At this time, the louver 16 flips backward and closes to protect the charging pile. When the upper end of the baffle 19 moves upward and touches the upper contact of the micro switch 18, the signal is fed back to the charging pile control system. The charging pile control system sends a stop signal to the linear motor 4, and the drive mechanism stops. At this time, the louver 16 is in the closed state.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
