Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a protective device for outdoor new energy charging piles. Background Technology

[0002] Charging piles are energy-saving devices that provide charging services for electric vehicles. They are mainly divided into ground-mounted charging piles and wall-mounted charging piles. They mainly adopt time-based, electricity-based, and fee-based charging methods. Charging piles are installed in public buildings such as public buildings, shopping malls, public parking lots, and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. Charging piles are often installed in open-air environments and need to be protected.

[0003] However, most charging stations are installed on the ground outdoors. In actual use, when drivers are reversing or parking in parking lots, they are prone to direct collisions between their vehicles and charging stations due to improper operation. Because charging stations and their internal electrical components are quite sophisticated and lack effective buffer protection mechanisms, such collisions often cause serious consequences such as deformation of the charging station's outer shell, breakage of internal wiring, and damage to core components, thereby affecting the normal use of the charging station.

[0004] In view of this, we have studied and improved the existing problems to provide an outdoor new energy charging pile protection device, aiming to solve the problems and improve its practical value through this technology. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an outdoor new energy charging pile protection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor new energy charging pile protection device, comprising a base and a chassis installed on the top of the base, bolts being installed around the surface of the base, an anti-collision mechanism being provided on the front of the chassis, the anti-collision mechanism comprising a damping tube installed on the side wall of the chassis, a piston sliding inside the damping tube, a buffer rod being fixed to one end of the piston, a slide rail being fixed to one end of the buffer rod being provided on the front of the chassis, a slider sliding inside the slide rail, a rotating rod being hinged to the surface of the slider, a connecting frame being hinged to one end of the rotating rod, a protective plate being fixed to one side of the connecting frame, a spring A being provided inside the slide rail, a spring B being sleeved on the outer wall of the buffer rod, and a connecting pipe being connected to one end of the damping tube; A clamping mechanism is provided above the bolt. The clamping mechanism includes a pressure block movably installed above the bolt. A metal tube is slidably provided at the top of the pressure block. A rotating shaft is rotatably provided inside the connecting pipe. A fan blade is sleeved on the outer wall of the rotating shaft. A vertical pipe is fixed to the side wall of the chassis. A circular plate is threadedly connected to the outer wall of the rotating shaft inside the vertical pipe. An air supply pipe is connected between the vertical pipe and the metal pipe. An auxiliary mechanism is provided on the back of the protective plate.

[0007] Preferably, the piston has multiple sets of air cushions on its front side, and the multiple sets of air cushions are arranged in a linear manner.

[0008] Preferably, one end of the spring A is fixedly connected to the side wall of the slider, and the other end of the spring A is fixedly connected to the inner wall of the slide rail.

[0009] Preferably, one end of the spring B is fixedly connected to one side of the piston, and the other end of the spring B is fixedly connected to the inner wall of the damping tube.

[0010] Preferably, one end of the connecting pipe is connected to a storage cylinder, and the inner wall of the damping pipe is filled with hydraulic oil.

[0011] Preferably, the auxiliary mechanism includes a magnetic block A fixed to the back of the protective plate, a housing fixed to the side wall of the chassis, a threaded rod rotatably provided inside the housing, a push plate threaded to the outer wall of the threaded rod, an L-shaped rod fixed to one side of the push plate, and a magnetic block B parallel to the magnetic block A fixed to one end of the L-shaped rod.

[0012] Preferably, bevel gear A and bevel gear B are respectively installed on the outer wall of the rotating shaft and the threaded rod, and bevel gear A and bevel gear B mesh with each other.

[0013] Preferably, magnetic block A and magnetic block B have the same magnetism on opposite sides, and magnetic block A and magnetic block B have the same size.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a protective plate that moves towards the charging pile chassis upon impact. This movement causes the connecting frame to rotate and separate the two sets of rotating rods, driving the two sliders inside the slide rail to slide in opposite directions and compress spring A. This initial buffering of impact energy occurs through elastic deformation. If the impact force is large, the protective plate moves the slide rail to push the buffer rod into the damping tube, causing the piston to squeeze the hydraulic oil. The hydraulic oil is then slowly discharged into the storage cylinder through the connecting pipe. This utilizes the fluid damping effect to achieve secondary buffering, effectively reducing the direct impact of the collision on the charging pile chassis. This prevents damage to the internal electrical components of the chassis due to the impact, ensuring the structural integrity and operational safety of the charging pile in complex outdoor environments.

[0015] 2. This invention utilizes the hydraulic oil flowing inside the connecting pipe. The flowing hydraulic oil impacts the fan blades, causing them to rotate. The rotation of the fan blades drives the connected shaft to rotate synchronously. The rotation of the shaft causes the circular plate to move downwards along the inside of the vertical pipe, compressing the gas inside the vertical pipe. The compressed gas enters the metal pipe through the gas supply pipe, increasing the gas pressure inside the metal pipe. This increased gas pressure then exerts a squeezing effect on the pressure block installed above the bolt, ultimately squeezing the bolt. Thus, the flow of hydraulic oil converts the energy generated by the collision into a clamping force on the bolt, effectively preventing the bolt from loosening due to external collisions and other factors. This ensures the stability of the connection between the base and the installation foundation, further improving the installation stability and reliability of the entire device.

[0016] 3. This invention utilizes the principle that when the rotating shaft rotates, it drives the bevel gear A to rotate synchronously. The rotation of bevel gear A drives the bevel gear B to rotate, which in turn drives the threaded rod to rotate inside the housing. The rotation of the threaded rod causes the push plate, which is threaded to it, to move linearly along the inside of the housing. The linear movement of the push plate, in turn, causes the L-shaped rod, which is fixed to it, to move synchronously. This causes the magnetic block B, which is fixed at one end of the L-shaped rod, to gradually move closer to the magnetic block A, which is fixed on the back of the protective plate. Since the magnetic blocks A and B have the same magnetism on opposite sides, they will generate a gradually increasing mutual repulsion force as they approach each other. This mutual repulsion force will form a reverse buffering resistance on the protective plate. Thus, by utilizing the mutual repulsion force between magnetic blocks A and B, which increases as the distance between them decreases, the protective plate can be provided with additional damping buffering effect. This effectively distributes the impact force borne by the protective plate, further improving the impact resistance and buffering stability of the protective plate, and preventing the chassis from being damaged by excessive impact force.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] See Figures 1 to 7 As shown, the present invention provides an outdoor new energy charging pile protection device, including a base 1 and a housing 2 installed on the top of the base 1. Bolts 6 are installed around the surface of the base 1. The front of the housing 2 is provided with an anti-collision mechanism 3. The anti-collision mechanism 3 includes a damping tube 37 installed on the side wall of the housing 2. A piston 310 slides inside the damping tube 37. A buffer rod 38 is fixed to one end of the piston 310. A slide rail 32 is fixed to one end of the buffer rod 38 and is located on the front of the housing 2. A slider 33 slides inside the slide rail 32. A rotating rod 35 is hinged to the surface of the slider 33. A connecting frame 34 is hinged to one end of the rotating rod 35. A protective plate 31 is fixed to one side of the connecting frame 34. A spring A36 is provided inside the slide rail 32. A spring B39 is sleeved on the outer wall of the buffer rod 38. A connecting pipe 311 is connected to one end of the damping tube 37. It should be noted that when the front of chassis 2 is impacted, the external impact force first acts on the protective plate 31, causing the protective plate 31 to move closer to chassis 2. This causes the connecting frame 34 to move synchronously, transmitting the impact force to the two sets of hinged rotating rods 35 through the connecting frame 34. Affected by the impact force, the two sets of rotating rods 35 rotate and move away from each other, thereby causing the two sliders 33 inside the slide rail 32 to slide in opposite directions. The sliding of the sliders 33 compresses the spring A36 inside the slide rail 32, further absorbing the impact energy using the elastic deformation characteristics of the spring A36, thus buffering the impact force. If the impact force is large, the protective plate 31 continues to move towards chassis 2, causing the slide rail 32 to move synchronously. The displacement-driven buffer rod 38 extends into the damping tube 37, pushing the piston 310 to slide along the inner wall of the damping tube 37 towards the rear end. At this time, the hydraulic oil filled in the damping tube 37 is squeezed by the piston 310 and slowly discharged into the storage cylinder 312 through the connecting pipe 311. During the flow of the hydraulic oil, a large amount of impact energy is consumed by the fluid damping effect, realizing secondary buffering. At the same time, during the movement of the buffer rod 38, the spring B39 sleeved on its outer wall will be stretched. The elastic tension of the spring B39 forms a reverse force, further offsetting part of the impact force, effectively weakening the direct effect of the collision impact force on the charging pile chassis 2, avoiding damage to the electrical components inside the chassis 2 due to the impact, and ensuring the structural integrity and safety of the charging pile in complex outdoor environments.

[0021] A clamping mechanism 4 is provided above the bolt 6. The clamping mechanism 4 includes a pressure block 45 movably installed above the bolt 6. A metal tube 46 is slidably provided at the top of the pressure block 45. A rotating shaft 41 is rotatably provided inside the connecting pipe 311. A fan blade 42 is sleeved on the outer wall of the rotating shaft 41. A vertical pipe 43 is fixed on the side wall of the casing 2. A circular plate 44 is threadedly connected to the outer wall of the rotating shaft 41 inside the vertical pipe 43. An air supply pipe 47 is connected between the vertical pipe 43 and the metal tube 46. It should be noted that when the hydraulic oil in the anti-collision mechanism 3 flows inside the connecting pipe 311, the flowing hydraulic oil impacts the fan blade 42, causing the fan blade 42 to rotate. The rotation of the fan blade 42 will drive the shaft 41 connected to it to rotate synchronously. Since the part of the shaft 41 that penetrates into the vertical pipe 43 is threadedly connected to the circular plate 44, the rotation of the shaft 41 will drive the circular plate 44 to move downward along the inside of the vertical pipe 43, so that the circular plate 44 will compress the gas inside the vertical pipe 43. The compressed gas enters the metal pipe 46 through the gas supply pipe 47, which increases the air pressure inside the metal pipe 46. The increased air pressure then exerts a squeezing effect on the pressure block 45 that is movably installed above the bolt 6, and finally achieves the squeezing of the bolt 6 by the pressure block 45. Thus, the energy generated by the collision can be converted into a clamping force on the bolt 6 by means of the flow of hydraulic oil, thereby effectively preventing the bolt 6 from loosening due to external collisions and other factors, ensuring the stability of the connection between the base 1 and the installation foundation, and further improving the installation stability and reliability of the entire device.

[0022] An auxiliary mechanism 5 is provided on the back of the protective plate 31.

[0023] See Figure 3 As shown, the piston 310 has multiple sets of air cushions on its front side. These air cushions are arranged in a linear pattern. The multiple sets of linearly arranged air cushions can help buffer the impact force of the collision and reduce the hard contact between the piston 310 and the damping tube 37.

[0024] See Figures 3 to 4 As shown, one end of spring A36 is fixedly connected to the side wall of slider 33, and the other end of spring A36 is fixedly connected to the inner wall of slide rail 32.

[0025] See Figure 3 As shown, one end of spring B39 is fixedly connected to one side of piston 310, and the other end of spring B39 is fixedly connected to the inner wall of damping tube 37.

[0026] See Figure 3 As shown, one end of the connecting pipe 311 is connected to the storage cylinder 312. The inner wall of the damping pipe 37 is filled with hydraulic oil. The storage cylinder 312 is used to store the hydraulic oil in the damping pipe 37 to ensure the stable circulation of hydraulic damping.

[0027] See Figures 5 to 7 As shown, the auxiliary mechanism 5 includes a magnetic block A51 fixed to the back of the protective plate 31, a housing 53 fixed to the side wall of the chassis 2, a threaded rod 54 rotatably provided inside the housing 53, a push plate 55 threadedly connected to the outer wall of the threaded rod 54, an L-shaped rod 56 fixed to one side of the push plate 55, and a magnetic block B52 parallel to the magnetic block A51 fixed to one end of the L-shaped rod 56.

[0028] See Figures 5 to 6As shown, bevel gear A57 and bevel gear B58 are respectively installed on the outer walls of the rotating shaft 41 and the threaded rod 54, and bevel gear A57 and bevel gear B58 mesh with each other.

[0029] See Figures 5 to 7 As shown, magnetic blocks A51 and B52 have the same magnetism on opposite sides, and magnetic blocks A51 and B52 have the same size.

[0030] It should be noted that when the rotating shaft 41 rotates, it drives the bevel gear A57 mounted on its outer wall to rotate synchronously. Since the bevel gear A57 meshes with the bevel gear B58 on the outer wall of the threaded rod 54, the rotation of the bevel gear A57 drives the bevel gear B58 to rotate accordingly, thereby driving the threaded rod 54 to rotate stably inside the housing 53. The rotation of the threaded rod 54 causes the push plate 55, which is threadedly connected to it, to move linearly along the inside of the housing 53. The linear movement of the push plate 55, in turn, causes the L-shaped rod 56, which is fixedly connected to it, to produce synchronous displacement, causing the magnetic block B52 fixed at one end of the L-shaped rod 56 to move towards... As the magnetic block A51 fixed to the back of the protective plate 31 gradually approaches, and because the magnetic blocks A51 and B52 have the same magnetism on opposite sides, they will generate a gradually increasing mutual repulsion force as they approach. This mutual repulsion force will form a reverse buffering resistance on the protective plate 31. Thus, by utilizing the mutual repulsion force between magnetic blocks A51 and B52, which increases as the distance decreases, the protective plate 31 can be provided with additional damping buffering effect, thereby effectively distributing the impact force borne by the protective plate 31, further improving the impact resistance and buffering stability of the protective plate 31, and preventing the chassis 2 from being damaged due to excessive collision impact force.

[0031] Working principle: When the front of chassis 2 is impacted, the external impact force first acts on the protective plate 31, causing the protective plate 31 to move closer to chassis 2. This causes the connecting frame 34 to move synchronously, transmitting the impact force to the two sets of hinged rotating rods 35 through the connecting frame 34. Affected by the impact force, the two sets of rotating rods 35 rotate and move away from each other, thereby causing the two sliders 33 inside the slide rail 32 to slide in opposite directions. The sliding of the sliders 33 compresses the spring A36 inside the slide rail 32, utilizing the elastic deformation characteristics of the spring A36 to further absorb the impact energy, thus buffering the impact force. If the impact force is large... The protective plate 31 continuously moves towards the chassis 2 and drives the slide rail 32 to move synchronously. The displacement of the slide rail 32 drives the buffer rod 38 to extend into the damping tube 37, pushing the piston 310 to slide along the inner wall of the damping tube 37 towards the rear end. At this time, the hydraulic oil filled in the damping tube 37 is squeezed by the piston 310 and slowly discharged into the storage cylinder 312 through the connecting pipe 311. During the flow of the hydraulic oil, a large amount of impact energy is consumed by the fluid damping effect to achieve secondary buffering. At the same time, during the movement of the buffer rod 38, the spring B39 sleeved on its outer wall will be stretched. The elastic tension of the spring B39 forms a reverse force, further offsetting part of the impact force. When the hydraulic oil in the anti-collision mechanism 3 flows inside the connecting pipe 311, the flowing hydraulic oil impacts the fan blade 42, causing the fan blade 42 to rotate. The rotation of the fan blade 42 will drive the shaft 41 connected to it to rotate synchronously. Since the part of the shaft 41 that penetrates into the vertical pipe 43 is threadedly connected to the circular plate 44, the rotation of the shaft 41 will drive the circular plate 44 to move downward along the inside of the vertical pipe 43, so that the circular plate 44 will compress the gas inside the vertical pipe 43. The compressed gas enters the metal pipe 46 through the gas supply pipe 47, which increases the gas pressure inside the metal pipe 46. The increased gas pressure then exerts a squeezing effect on the pressure block 45 that is movably installed above the bolt 6, ultimately achieving the squeezing of the bolt 6 by the pressure block 45. When the shaft 41 rotates, it drives the bevel gear A57 mounted on its outer wall to rotate synchronously. Since the bevel gear A57 meshes with the bevel gear B58 on the outer wall of the threaded rod 54, the rotation of the bevel gear A57 will drive the bevel gear B58 to rotate accordingly, thereby driving the threaded rod 54 to rotate stably inside the housing 53. The rotation of the threaded rod 54 will cause the push plate 55, which is threaded to it, to move linearly along the inside of the housing 53. The linear movement of the push plate 55 will drive the L-shaped rod 56, which is fixed to it, to produce synchronous displacement. This causes the magnetic block B52, which is fixed at one end of the L-shaped rod 56, to gradually move closer to the magnetic block A51 fixed on the back of the protective plate 31. Since the magnetic blocks A51 and B52 have the same magnetism on opposite sides, they will generate a gradually increasing mutual repulsion force during the process of approaching each other. This mutual repulsion force will form a reverse buffering resistance on the protective plate 31.
