Description

Technical Field

[0001] This utility model relates to the field of charging pile protection technology, specifically to an automatic protective cover. Background Technology

[0002] A charging station is a device that provides power for electrically driven transportation equipment. This equipment includes electric vehicles, electric bicycles, drones, electric skateboards, and self-balancing scooters. The main components of a charging station include a casing, charging interface, charging controller, display screen, payment system, communication module, cooling system, and safety protection devices. The casing is typically made of weather-resistant materials, providing waterproof and dustproof protection for the internal components. The charging interface is equipped with various types to meet the needs of different transportation devices. The charging controller regulates current and voltage to ensure safe and efficient charging, while the display screen provides information such as charging status and cost for user convenience.

[0003] Charging stations are widely used, including public charging stations, residential areas, office buildings, highway service areas, and taxi and car-sharing parking lots. To facilitate charging of transportation equipment, most charging stations are installed outdoors. Although the outer casing of the charging station is waterproof, many of its interfaces are exposed, posing a risk of water ingress. Water ingress into the charging interfaces can easily lead to electrical short circuits, leakage, corrosion and oxidation, unstable charging, and reduced equipment lifespan. To prevent water ingress, rain shelters can be installed to shield the charging station and prevent rainwater from entering the charging interfaces.

[0004] To increase renewable energy utilization, reduce energy costs, alleviate grid burden, and support electricity storage, some existing charging stations are equipped with solar panels on top to enhance electricity storage. However, while existing rain shelters protect the charging stations from rain, snow, and hail, they also block sunlight, affecting the effectiveness of the solar panels. To address these issues, an automatic protective cover is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic protective cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic protective cover, comprising two uprights and a folding canopy;

[0007] The upper end of the column is rotatably mounted with a foldable crossbar, and the folding canopy is connected between the two crossbars by a pull rope;

[0008] Support rod;

[0009] The support rod can be folded, and its two ends are rotatably connected to the outer wall of the column and the end of the crossbar away from the column, respectively.

[0010] The upper end of the column is fixedly equipped with a weather sensor, and two motors are installed on the outer wall of the column to drive the crossbar and support rod to rotate. The sensor is connected to the motor circuit.

[0011] After sensing the humid weather, the sensor drives the motor, which in turn rotates the crossbars and support rods to support the folding awning and unfold it.

[0012] As a preferred technical solution of this utility model, a base plate is installed at the lower end of the column to increase the contact area with the ground.

[0013] As a preferred technical solution of this utility model, the folding tent is made of polyester Oxford cloth with a PVDF coating on the surface.

[0014] As a preferred technical solution of this utility model, the sensing device includes a protective cabin and multiple sensors, with the protective cabin covering the multiple sensors.

[0015] As a preferred technical solution of this utility model, the sensor includes a wind speed sensor, a piezoelectric sensor, a photosensitive sensor, and a temperature and humidity sensor.

[0016] As a preferred technical solution of this utility model, the crossbar includes a first rotating rod, a first support rod, and a connecting member. One end of the first rotating rod is rotatably connected to the outer wall of the column, one end of the first support rod is rotatably connected to the end of the first rotating rod away from the column, and the connecting member is rotatably connected to one end of the first rotating rod.

[0017] As a preferred technical solution of this utility model, the connector is a vertical corner bracket.

[0018] As a preferred technical solution of this utility model, the support rod includes a second rotating rod, a second support rod, and a connecting rod.

[0020] This invention uses a sensor to detect humid weather and then drives a motor to rotate the crossbars and support rods to support the folding awning. This allows the awning to unfold and shield the charging station during rain or snow. On sunny days, the awning can be retracted to ensure that the solar panels on the charging station can receive sunlight. This solves the problem that existing awnings used to protect charging stations block sunlight and affect the use of solar panels. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This embodiment provides an automatic protective cover, including a column 1, such as... Figure 1 As shown, there are two columns 1, which are used to install on the rear sides of the charging pile. The charging pile is not shown in the figure, and the charging pile is a solar charging pile with patent publication number CN109159694A.

[0027] Column 1 is mounted on a cement base via a screw rod. To increase the stability of column 1, as follows: Figure 1 As shown, a base plate is fixedly connected to the lower end of column 1, and a triangular support plate is welded between column 1 and the base plate. The base plate increases the contact area between the lower end of column 1 and the cement base, thereby increasing the stability of column 1.

[0028] like Figure 1 As shown, a folding canopy 4 is installed between the two columns 1. To facilitate the unfolding and folding of the folding canopy 4, a crossbar 2 and a support rod 3 are installed on the columns 1, as shown. Figure 1 As shown, the crossbars 2 and the uprights 1 are perpendicularly distributed, symmetrically arranged, and both on a parallel plane. The uprights 1, crossbars 2, and support rods 3 form a right-angled triangle structure. The two sides of the folding canopy 4 are connected to the two crossbars 2 by ropes, and the folding canopy 4 is positioned directly above the charging pile, providing shelter from wind and rain. Both the crossbars 2 and the support rods 3 can be mechanically folded, causing the folding canopy 4 to retract.

[0029] like Figure 2 As shown, the crossbar 2 includes a first rotating rod 21, a first support rod 22, and a connector 23. One end of the first rotating rod 21 is rotatably connected to the column 1, and a first motor for driving the first rotating rod 21 to rotate is vertically mounted on the column 1. One end of the first support rod 22 is rotatably connected to the end of the first rotating rod 21 away from the column 1. The connector 23 is set as a vertical angle bracket, and the end of the first support rod 22 away from the first rotating rod 21 is rotatably connected to the upper end of the connector 23.

[0030] Similarly, Figure 2 As shown, the support rod 3 includes a second rotating rod 31, a second support rod 32, and a connecting rod 33. One end of the second rotating rod 31 is also rotatably connected to the column 1, and a second motor for driving the rotation of the second rotating rod 31 is horizontally mounted on the column 1. The two ends of the second support rod 32 are respectively rotatably connected to the end of the second rotating rod 31 away from the column 1 and the end of the connecting rod 33. The end of the connecting rod 33 away from the second rotating rod 31 is rotatably connected to the inner wall of the connecting member 23. At this time, the rotating connection surface of the second rotating rod 31 and the connecting member 23 is perpendicular to the connection surface of the first rotating rod 21 and the connecting member 23.

[0031] The folding tent 4 is made of polyester Oxford cloth, and the surface of the folding tent 4 is coated with PVDF (polyvinylidene fluoride). Polyester Oxford cloth has the advantages of being wear-resistant, waterproof, lightweight, wrinkle-resistant, light-resistant, easy to clean, and corrosion-resistant. The PVDF coating enhances the wear resistance and UV (ultraviolet) protection of the folding tent 4.

[0032] The uprights 1, crossbars 2, and support rods 3 are all made of aluminum alloy, combining the advantages of lightweight and high strength. In use, two first motors and two second motors are started simultaneously. When the two first motors start, they drive the two first rotating rods 21 to rotate synchronously. At this time, one end of the two first rotating rods 21 approaches each other. The support rod 3, through the connector 23, limits the first support rod 22, ensuring that the end of the first support rod 22 away from the first rotating rod 21 always moves on a vertical plane. When the two second motors start, they drive one end of the second rotating rod 31 to rotate upwards, causing the support rod 3 to fold into an N-shaped structure. The synchronous folding of the crossbars 2 and support rods 3 drives the flexible folding tent 4 to fold and retract.

[0033] like Figure 1 As shown, in order to automatically control the folding and unfolding of the folding tent 4, a sensing device 5 is installed on the upper end of the column 1. The sensing device 5 includes a protective cabin and multiple sensors. The protective cabin covers the multiple sensors and is made of transparent plastic material, which protects the sensors without affecting their ability to sense changes in the external environment.

[0034] Multiple sensors are controlled by microcontroller units (MCUs), such as STM32 and ESP32. The charging pile powers the first motor, second motor, and sensors. The sensors and other sensor accessories are based on equipment manufactured by Shandong Tianhe Environmental Technology Co., Ltd. The sensors are electrically connected to the first and second motors. These sensors include wind speed sensors, piezoelectric sensors, photosensors, and temperature and humidity sensors. A cup-type wind speed sensor is preferred, installed at the top or side of the protective chamber. A threshold value (e.g., >13.8 m / s or level 6 wind) triggers the start of both motors. The piezoelectric sensor triggers when continuous rainfall or hail impacts, also starting both motors. The photosensor assists in determining day / night or detecting changes in ambient light (e.g., heavy cloud cover), triggering on cloudy days or at night. The temperature and humidity sensor monitors ambient temperature and humidity, assisting the system in determining humidity levels. It triggers when humidity is too high (>70%), also starting both motors. When any core sensor (wind, rain, hail) reaches a preset threshold, or when a specific combination of conditions (such as strong wind + rain) is met, it can trigger the two motors to start synchronously, causing the folding tent 4 to unfold. After all the core sensor signals that trigger the unfolding remain below the safety threshold for a period of time (for example, no rain for 5 minutes, wind speed below the safety threshold for 10 minutes), the output shafts of the two motors are triggered to rotate in opposite directions, causing the folding tent 4 to fold and retract.

[0035] The column 1 also has a built-in small-capacity backup battery (for emergency recovery or safe operation in case of main power failure). The sensor 5 and the motor are mainly powered by the main power of the charging pile, while the backup battery is used to manage charging and discharging and low power warning.

[0036] During the rotation and unfolding of the crossbar 2 and support rod 3 into a straight rod, although the speeds of the first motor and the second motor are not the same, the second support rod 32 and the connecting rod 33 can perform motion compensation to ensure that the crossbar 2 and support rod 3 can eventually become straight rod structures to open the folding tent 4. When the support rod 3 is a straight rod structure, the support rod 3 supports the crossbar 2 to ensure the stability of the crossbar 2.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
