Description

Technical Field

[0001] The present invention belongs to the technical field of charging piles, and in particular relates to a protective device for an electric bicycle charging pile. Background Art

[0002] Charging piles, the infrastructure for e-bikes, are increasing in number and distribution, leading to a sharp increase in charging demand. This increase in the number of charging piles also raises the issue of charging safety. During the charging process, e-bikes may face risks such as battery overcharging, short circuits, and overheating, leading to safety accidents such as fires and explosions. These accidents not only cause property damage but also threaten the personal safety of users. To improve charging safety and ensure the normal operation of e-bike charging piles, it is particularly important to design and install charging pile protection devices. These protection devices can promptly detect and respond to abnormal conditions during charging, such as current overloads and excessive temperatures, automatically cutting off the power supply to prevent accidents. Furthermore, protection devices can effectively monitor the charging process to ensure that the battery is not affected by overcharging, thereby extending battery life.

[0003] When electric bicycle charging piles are used daily, since electric bicycles need to be charged outdoors, in order to cope with weather factors, it is often necessary to install a semi-open transparent cover on the outside of the electric bicycle charging pile socket. Although the semi-open transparent cover can prevent rain from falling directly on the charging socket, due to the openness of the structure or design omissions, rainwater will seep in from the side or bottom, especially under windy and rainy weather conditions, which will still cause water stains or moisture inside the charging pile, increasing the risk of short circuit or other failures in the electrical part. In addition, it cannot fully provide good ventilation, especially in summer or high temperature weather, the interior of the charging pile will cause poor heat dissipation due to heat accumulation. If the charging pile cannot effectively dissipate heat, it will affect the battery charging efficiency and even shorten the service life of the equipment, or cause overheating failure. Moreover, if the semi-open design does not have sufficient protective measures, it will also cause the socket to be partially exposed to the external environment, increasing the risk of collision with external objects, dust accumulation and even animal invasion. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an electric bicycle charging pile protection device.

[0005] The technical solution adopted to solve the above technical problems is: a protective device for an electric bicycle charging pile, comprising a charging pile bracket, the interior of the charging pile bracket is a hollow structure for placing wires, and a shield is fixedly connected to the front of the charging pile bracket, and the shield is arranged in a trapezoidal structure as a whole, and the bottom of the shield is arranged in an open state. An air pushing component is arranged inside the shield to improve the waterproof, moisture-proof, dust-proof and heat dissipation performance of the charging pile, and an extending component is installed inside the air pushing component to improve the performance of the charging pile in windy and rainy weather and ensure the dryness of the charging area.

[0006] Through the above technical solution, when the socket is extended, it can prevent the socket from being directly exposed to rainwater, thereby reducing the risk of moisture entering the socket. At the same time, the circular rotation and back and forth movement of the fan can help drain the accumulated water around the socket and ensure that the socket remains dry.

[0007] Furthermore, the air pushing component includes a fixing part fixedly connected to the charging pile bracket, and the fixing part is fixedly connected to an inner gear ring at the center of a side away from the charging pile bracket, a rotating plate is rotatably connected at the center of the inner gear ring, and the rotating plate connecting shaft is rotatably connected to the inner gear ring and the fixing part, and the through end of the rotating plate connecting shaft is located inside the charging pile bracket, a driving motor is installed on the side of the charging pile bracket away from the shield, and the output end of the driving motor is rotatably connected to the charging pile bracket, and the through end of the driving motor is fixedly connected to the through end of the rotating plate connecting shaft.

[0008] Through the above technical solution, the extended socket combined with the fan design can further stabilize the charging environment, reduce the direct contact between the socket and the outside world, and eliminate moisture and accumulated water inside the charging pile, reducing the risk of electrical failure or unstable charging caused by water vapor and humidity, and improving the reliability of the charging process.

[0009] Furthermore, the rotating plate is rotatably connected to a driven gear at one end away from the center of the inner gear ring, and the driven gear is meshed with the inner teeth of the inner gear ring for transmission. The rotating plate is slidably connected to a first slide rod with a T-shaped structure on the side away from the driven gear, and a slide groove is provided on the first slide rod on the side away from the rotating plate. The driven gear is fixedly connected to a second slide rod with an L-shaped structure at the center of the side facing the first slide rod, and the end of the second slide rod away from the driven gear is located in the slide groove of the first slide rod, and at the same time, the second slide rod is slidably connected to the first slide rod on the end away from the driven gear.

[0010] Furthermore, the fixing member is rotatably connected to a rotating frame inside, and a plurality of filter plates symmetrically distributed in a circumference are fixedly connected to the outside of the rotating frame. A first support plate and a second support plate are provided between the rotating frame and the first sliding rod, and the first support plate and the second support plate are rotatably connected at both ends of the second support plate. At the same time, the connecting shafts at both ends of the second connecting plate are rotatably connected to the first support plate and the second support plate, and the connecting shafts at both ends of the second connecting plate are fixedly connected to the first connecting plate and the third connecting plate respectively. The middle parts of the first support plate and the second support plate are rotatably connected to a folding plate with an L-shaped structure, and the folding plate is fixedly connected to the fan at one end away from the first support plate.

[0011] Through the above technical solution, the fan can effectively drain and dehumidify, preventing the impact of water accumulation and humid environment on the equipment. The charging pile itself can therefore reduce failures or damage caused by windy and rainy weather, reduce the frequency of maintenance and overhaul, and save operating costs.

[0012] Furthermore, the first connecting plate, the third connecting plate and the second connecting plate are arranged in a triangular structure, the first connecting plate at one end of the first support plate is rotatably connected to the first sliding rod, and the third connecting plate at one end of the second support plate is rotatably connected to the first sliding rod, the first connecting plate at the other end of the first support plate is rotatably connected to the rotating frame, and the third connecting plate at the other end of the second support plate is rotatably connected to the rotating frame, a servo motor is installed on the top of the first sliding rod, and the output end of the servo motor is rotatably connected to the first sliding rod, and the through end of the servo motor is fixedly connected to the first connecting plate.

[0013] Through the above technical solution, in windy and rainy weather, the charging pile may be disturbed by external weather conditions, causing instability in the charging process. The role of the fan is to promote air flow and prevent the charging pile from overheating or inefficiency due to moisture or water accumulation, thereby ensuring a stable and smooth charging process and avoiding charging interruptions due to equipment overheating or failure.

[0014] Furthermore, a conductive tube is rotatably connected to the connection between the rotating plate and the inner gear ring, and the through-end of the conductive tube is fixedly connected to the charging pile bracket. At the same time, the through-end of the conductive tube is located inside the charging pile bracket and electrically connected to the wire. The extending component includes a fixed plate fixedly connected to the conductive tube, and a second connecting frame is provided on one side of the fixed plate. Two gear sets are rotatably connected on both sides of the second connecting frame, and the two gear sets are respectively located at the diagonal ends of the second connecting frame. At the same time, the two gear sets are symmetrically arranged, and the gears in the gear set are fixedly connected to the second rotating plate on the side away from the second connecting frame.

[0015] Furthermore, the second rotating plate connected by the two gears in the gear group is rotatably connected to the first rotating plate and the third rotating plate at one end away from the gear group, and the two first rotating plates are rotatably connected to the first connecting frame at one end away from the second rotating plate, and the first connecting frame is fixedly connected to the fixed plate, and a hydraulic rod is rotatably connected to one side of the fixed plate, and the telescopic end of the hydraulic rod is rotatably connected to the first rotating plate.

[0016] Through the above technical solution, the combined design of the circularly rotating fan and the forward and backward movement enables the fan to adapt to wind and rain environments, ensuring that it can still operate stably even in bad weather. Through the movement of the fan, it can provide stronger protection performance and improve the adaptability of the charging pile to various environmental factors.

[0017] Furthermore, the two third rotating plates are rotatably connected to a third connecting frame away from one end of the first rotating plate, and a socket is installed on one side of the third connecting frame. A wire is installed between the first connecting frame and the second connecting frame, and one end of the wire is fixedly connected to the second rotating plate and then electrically connected to the wire inside the charging pile bracket. The other end of the wire is fixedly connected to the third connecting frame, and the through-end of the wire is electrically connected to the socket.

[0018] Through the above technical solution, the circular rotation of the fan can cover a wider area, helping to evenly remove the hot air around the socket and avoid local overheating. Through the function of moving back and forth, the fan can provide airflow in different directions and positions, further enhancing the heat dissipation effect. Especially when charging at high temperature or high load, it can effectively prevent the charging pile from overheating, thereby extending the life of the equipment and improving charging efficiency.

[0019] The beneficial effects of the present invention are as follows: (1) The present invention can drive the rotating plate to rotate by driving the motor, and the third rotating plate rotates synchronously, so that the third rotating plate moves along the inside of the inner gear ring, prompting the third rotating plate to rotate while performing orbital revolution, so that the second slide bar follows the driven gear to perform synchronous movement, and then the second slide bar slides at one end in the first slide bar slot, so that the first slide bar performs linear reciprocating motion on the top of the rotating plate, and the servo motor and other components on the top of the first slide bar can perform linear reciprocating motion on the horizontal plane of the inner gear ring while performing orbital revolution, which can help to remove water accumulated around the charging pile and prevent water from being retained around the socket for a long time, especially in the case of heavy rain or wind and rain, the fan can take away water droplets to prevent water from entering the charging port, thereby reducing the risk of short circuit or electrical failure;

[0020] (2) The present invention drives the first connecting plate to rotate by the operation of a servo motor. Due to the fixed connection between the first connecting plate, the third connecting plate and the second connecting plate, when the first connecting plate rotates, the second connecting plate and the third connecting plate rotate synchronously, so that the first support plate and the second support plate between the first connecting plate, the third connecting plate and the second connecting plate perform elliptical motion while the first support plate and the second support plate perform alternating motion, thereby driving the folding plate to rotate with the connection point with the fan as the origin, and then causing the fan to rotate to generate air flow, so that the fan can perform linear reciprocating motion on the horizontal plane of the inner gear ring while performing orbital revolution, and the fan rotates. The fan's rotation and forward and backward movement can effectively promote air flow on rainy days, accelerate water evaporation, and avoid malfunctions caused by moisture in the charging pile and socket area;

[0021] (3) The present invention drives the first rotating plate to rotate with the connection with the first connecting frame as the origin through the operation of the hydraulic rod, and the hydraulic rod as a whole rotates relative to the fixed plate, and the rotation of the first rotating plate can drive the second rotating plate to rotate synchronously, thereby moving the second connecting frame in the opposite direction of the first connecting frame, and under the action of the gear set, the second rotating plate on the other side of the second connecting frame synchronously drives the third rotating plate to rotate, and then pushes the third connecting frame out of the shield, so that the socket is located outside the shield as a whole, which is convenient for synchronous charging. The design of the extended socket makes it more convenient for users of electric bicycles to use, especially in rainy or windy weather conditions. Users do not need to bend over too much or adjust the angle of the bicycle to contact the socket. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] like Figures 1-11As shown, an electric bicycle charging pile protection device of the present embodiment includes a charging pile bracket 11. The interior of the charging pile bracket 11 is a hollow structure for placing wires, and a shield 12 is fixedly connected to the front of the charging pile bracket 11. At the same time, the shield 12 is arranged in a trapezoidal structure as a whole, and the bottom of the shield 12 is arranged in an open state. An air pushing component 2 is arranged inside the shield 12 to improve the waterproof, moisture-proof, dust-proof and heat dissipation performance of the charging pile. The air pushing component 2 includes a fixing part 22 fixedly connected to the charging pile bracket 11, and the fixing part 22 is rotatably connected to the rotating frame 23 inside. The rotating frame 23 is fixedly connected to a number of filter plates 24 arranged in a circumferentially symmetrical distribution outside. When the socket 311 is extended, it can prevent the socket 311 from being directly exposed The position of the fan 218 in the rain reduces the risk of moisture entering the socket 311. At the same time, the circular rotation and forward and backward movement of the fan 218 can help remove the accumulated water around the socket 311, ensuring that the socket 311 remains dry. A first support plate 215 and a second support plate 216 are provided between the rotating frame 23 and the first slide bar 28, and the first support plate 215 and the second support plate 216 are respectively rotatably connected to the second connecting plate 213 at both ends. At the same time, the connecting shafts at both ends of the second connecting plate 213 are rotatably connected to the first support plate 215 and the second support plate 216. The through ends of the connecting shafts at both ends of the second connecting plate 213 are respectively fixedly connected to the first connecting plate 212 and the third connecting plate 214. The first connecting plate 212, the third connecting plate 214 and the second connecting plate 213 are arranged in a triangular structure.

[0036] like Figure 2-Figure 11As shown, the first connecting plate 212 at one end of the first support plate 215 is rotatably connected to the first slide bar 28, and the third connecting plate 214 at one end of the second support plate 216 is rotatably connected to the first slide bar 28, the first connecting plate 212 at the other end of the first support plate 215 is rotatably connected to the rotating frame 23, and the third connecting plate 214 at the other end of the second support plate 216 is rotatably connected to the rotating frame 23, a servo motor 211 is installed on the top of the first slide bar 28, and the output end of the servo motor 211 is rotatably connected to the first slide bar 28, the extended socket 311 is combined with the design of the fan 218, can further stabilize the charging environment, reduce the direct contact between the socket 311 and the outside world, and eliminate moisture and water accumulation inside the charging pile, thereby reducing electrical failures caused by water vapor and moisture. The risk of power failure or unstable charging is reduced, and the reliability of the charging process is improved. At the same time, the servo motor 211 is fixedly connected to the first connecting plate 212 at the through end, and the first support plate 215 and the second support plate 216 are rotatably connected to a folding plate 217 with an L-shaped structure in the middle, and the folding plate 217 is fixedly connected to the end away from the first support plate 215 with a fan 218, and the fixing part 22 is fixedly connected to the center of the side away from the charging pile bracket 11 with an inner gear ring 26, and the center of the inner gear ring 26 is rotatably connected to a rotating plate 27, and the connection between the rotating plate 27 and the inner gear ring 26 is rotatably connected with a conductive tube 25, and the through end of the conductive tube 25 is fixedly connected to the charging pile bracket 11, and the through end of the conductive tube 25 is located inside the charging pile bracket 11 and is electrically connected to the wire.

[0037] like Figure 3-Figure 11 As shown, the rotating plate 27 is rotatably connected to the driven gear 29 at one end away from the center of the inner gear ring 26, and the driven gear 29 is meshed with the internal teeth of the inner gear ring 26 for transmission. The rotating plate 27 is slidably connected to the first slide bar 28 with a T-shaped structure on the side away from the driven gear 29, and the first slide bar 28 is penetrated and provided with a slide groove on the side away from the rotating plate 27. The center of the side of the driven gear 29 facing the first slide bar 28 is fixedly connected to the second slide bar 210 with an L-shaped structure, and the end of the second slide bar 210 away from the driven gear 29 is located in the slide groove of the first slide bar 28. The circular rotation and forward and backward movement functions of the fan 218 help to enhance the air circulation around the socket 311 to avoid air leakage. Air retention, good ventilation helps to reduce moisture or dirt accumulation in the air, keep the charging pile equipment clean, and reduce equipment damage or battery efficiency reduction caused by poor air circulation. At the same time, the second slide bar 210 is slidably connected to the first slide bar 28 at one end away from the driven gear 29, and the rotating plate 27 connecting shaft is rotatably connected to the inner ring 26 and the fixing part 22. At the same time, the through end of the rotating plate 27 connecting shaft is located inside the charging pile bracket 11. The driving motor 21 is installed on the side of the charging pile bracket 11 away from the shield 12, and the output end of the driving motor 21 is rotatably connected to the charging pile bracket 11. At the same time, the through end of the driving motor 21 is fixedly connected to the through end of the rotating plate 27 connecting shaft.

[0038] like Figure 4-11 As shown, an extension component 3 is installed inside the air pushing component 2 to improve the performance of the charging pile in windy and rainy weather and ensure the dryness of the charging area. The extension component 3 includes a fixed plate 31 that is fixedly connected to the conductive tube 25, and a second connecting frame 37 is provided on one side of the fixed plate 31. The combination design of the annular rotating fan 218 and the forward and backward movement enables the fan 218 to adapt to the wind and rain environment, ensuring that it can still operate stably even in bad weather. Through the movement of the fan 218, it can provide stronger protection performance and improve the adaptability of the charging pile to various environmental factors. The second connecting frame 37 is rotatably connected to two gear sets 36 on both sides. The second rotating plate 35 connected by the two gears in the gear set 36 is rotatably connected to the first rotating plate 34 and the third rotating plate 39 at one end away from the gear set 36. The fan 311 can effectively drain and dehumidify to prevent water accumulation and humid environment from affecting the equipment. The charging pile itself can therefore reduce failures or damages caused by windy and rainy weather, reduce the frequency of maintenance and overhaul, and save operating costs. The two third rotating plates 39 are rotated away from one end of the first rotating plate 34 and connected to the third connecting frame 310, and a socket 311 is installed on one side of the third connecting frame 310. A wire 38 is installed between the first connecting frame 33 and the second connecting frame 37, and one end of the wire 38 is fixedly connected to the second rotating plate 35 and then electrically connected to the wires inside the charging pile bracket 11. The other end of the wire 38 is fixedly connected to the third connecting frame 310. In windy and rainy weather, the charging pile may be affected by external weather conditions, causing unstable factors in the charging process, and the function of the fan 218 is to promote air flow to avoid overheating or low efficiency of the charging pile due to moisture or water accumulation, thereby ensuring a stable and smooth charging process and avoiding charging interruption due to equipment overheating or failure.

[0039] like Figure 5-Figure 11 The fan 218 is designed to help dry the moisture on the surface of the socket 311, especially on rainy days or when the humidity around the charging pile is heavy. The fan 218 moving back and forth can flexibly adjust the wind direction to reduce moisture accumulation inside the socket or charging device, and reduce the risk of short circuit or corrosion of electrical parts. The circular rotation ensures that the wind 218 can effectively cover more areas. The two first rotating plates 34 are rotatably connected to the first connecting frame 33 at one end away from the second rotating plate 35, and the first connecting frame 33 is fixedly connected to the fixed plate 31. One side of the fixed plate 31 is rotatably connected to the hydraulic rod 32, and the telescopic end of the hydraulic rod 32 is rotatably connected to the first rotating plate 34, and the two gear sets 36 are respectively located at the diagonal ends of the second connecting frame 37. At the same time, the two gear sets 36 are symmetrically arranged, and the gears in the gear set 36 are fixedly connected to the second rotating plate 35 at the side away from the second connecting frame 37.

[0040] The working principle of this embodiment is as follows. During daily use, when the user is charging, the hydraulic rod 32 drives the first rotating plate 34 to rotate with the connection with the first connecting frame 33 as the origin, and the hydraulic rod 32 as a whole rotates relative to the fixed plate 31, and the rotation of the first rotating plate 34 can push the second rotating plate 35 to rotate synchronously, thereby moving the second connecting frame 37 in the opposite direction of the first connecting frame 33, and under the action of the gear set 36, the second rotating plate 35 on the other side of the second connecting frame 37 synchronously pushes the third rotating plate 39 to rotate, and then pushes the third connecting frame 310 out of the shield 12, so that the socket 311 is located outside the shield 12 as a whole, which is convenient for synchronous charging.

[0041] During daily operation of the socket 311, the drive motor 21 can be operated to drive the rotating plate 27 to rotate, and the third rotating plate 39 rotates synchronously, so that the third rotating plate 39 moves along the inside of the inner ring gear 26, prompting the third rotating plate 39 to rotate while revolving, so that the second slide bar 210 follows the driven gear 29 to move synchronously, and then the second slide bar 210 slides at one end in the slide groove of the first slide bar 28, so that the first slide bar 28 performs linear reciprocating motion on the top of the rotating plate 27, which can make the servo motor 211 and other components on the top of the first slide bar 28 perform linear reciprocating motion on the horizontal plane of the inner ring gear 26 while revolving.

[0042] Then, the servo motor 211 operates to drive the first connecting plate 212 to rotate. Since the first connecting plate 212, the third connecting plate 214 and the second connecting plate 213 are fixedly connected, when the first connecting plate 212 rotates, the second connecting plate 213 and the third connecting plate 214 rotate synchronously, so that the first support plate 215 and the second support plate 216 between the first connecting plate 212, the third connecting plate 214 and the second connecting plate 213 perform elliptical motion. At the same time, the first support plate 215 and the second support plate 216 perform alternating motion, thereby driving the folding plate 217 to rotate with the connection with the fan 218 as the origin, thereby causing the fan 218 to rotate to generate air flow.

[0043] The fan 218 can perform linear reciprocating motion on the horizontal plane of the inner gear ring 26 while revolving, and the fan 218 can rotate on its own to maintain air circulation, thereby ensuring that the device temperature is within a suitable range, avoiding overheating or heat accumulation, and improving charging efficiency and device life.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
