Description

Technical Field

[0001] The present invention relates to the technical field of charging pile protection, and specifically relates to a protection device for an outdoor charging pile. Background Art

[0002] With the popularization of electric vehicles and the continuous growth of charging demand, the outdoor new energy charging pile market will embrace a broader development space. At the same time, with the continuous progress of technology and the reduction of costs, the penetration rate of outdoor new energy charging piles will also continue to increase. Since they are installed in outdoor environments, these charging piles usually have a high protection level, capable of effectively preventing dust and rain, ensuring normal operation in bad weather.

[0003] For existing charging piles, no corresponding protection devices are provided on both sides. When an electric vehicle driver accidentally hits the charging pile, a slight impact may cause scratches or dents on the surface of the charging pile. When the impact force is relatively large, it will affect the circuit board and other components inside the charging pile, and in severe cases, it cannot be used and requires maintenance.

[0004] In view of this, a protection device for an outdoor charging pile is proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a protection device for an outdoor charging pile. Through the design of the arc surface of the protection plate, the impact force can be dispersed along the curved surface, and the buffer plate can offset the impact force through shock-absorbing components, thereby reducing damage to the charging pile body.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A protection device for an outdoor charging pile, comprising: a charging pile body, a base, a protection plate, and a buffer assembly. The charging pile body is fixedly connected to the upper surface of the base, and an air flow chamber is provided inside the base;

[0007] The buffer assembly is symmetrically arranged on both sides of the charging pile body, and includes side plates fixedly connected to both sides of the charging pile body, shock-absorbing components arranged inside the side plates, buffer plates fixedly connected to the ends of the shock-absorbing components away from the side plates, and roller one and roller two arranged at both ends of the buffer plate;

[0008] A positioning component, including a gear rod, a winding drum meshed with the gear rod, and a fixing belt fixedly connected to the surface of the winding drum;

[0009] The protection plate is slidably connected to the surface of the buffer plate, and guide grooves are provided at its top and bottom. A guide rail is fixedly connected inside the top guide groove, and the guide rail is connected to the buffer plate. A telescopic hose is provided on the surface of the buffer plate near the bottom end of roller two;

[0010] On the front of the charging pile body, there are connection lines and a limiting ring. A gas outlet pipe is fixedly connected to the part near the limiting ring. An annular airbag layer is arranged on the inner wall of the limiting ring. The annular airbag layer is communicated with the air flow chamber through the gas outlet pipe. One end of the connection line is fixedly connected with a charging gun, and one end of the charging gun is inserted into the inside of the limiting ring;

[0011] At the bottom of the second roller, there is a fan blade. The fan blade is communicated with the air flow chamber through a telescopic hose, and is used to drive air to be filled into the annular airbag layer to lock the charging gun.

[0012] The present invention has the following beneficial effects:

[0013] 1. For the protection device of the outdoor charging pile, when the charging pile body is impacted, the protection plate is impacted first. By using the design of its arc surface, the impact force can be dispersed along the curved surface, thereby reducing the impact force on a specific point. When the impact force is relatively large, the impact force is transmitted to the buffer plate, and the impact force is further offset by the shock-absorbing parts and the side plates. When the impact increases, the first roller and the second roller can assist the protection plate to make the impact object slide quickly to both sides, reducing the damage to the charging pile body;

[0014] 2. For the protection device of the outdoor charging pile, through the positioning components arranged in the side plates and the buffer plate, the first roller and the second roller can be limited, reducing the sliding of the auxiliary protection plate during slight impacts. When the shock-absorbing parts push the gear rod to contract to both sides, the winding drum is synchronously driven to rotate, so that the fixing belt is wound on its surface. At this time, one end of the positioning rod moves out of the inside of the card slot. When the second roller rotates, the fan blade at its bottom rotates synchronously, and the formed air flow enters the inside of the annular airbag layer, causing it to expand and contact the inner wall of the limiting ring, which is convenient for reducing the situation of the charging gun falling off and protecting it when the charging pile body is impacted;

[0015] 3. For the protection device of the outdoor charging pile, when the charging pile body is slightly impacted, the protection plate slides along the guide rail. The spring on the surface of the guide rail can slow down the impact force, and the protection plate resets after sliding, which is convenient for repeated use. When the impact force is transmitted to the side plate, the auxiliary rod and the protective cover at its top can further share the impact force, reducing the damage to the charging pile body, and at the same time can shield rain for the charging pile body.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 to 9 , the present invention provides a protection device for an outdoor charging pile; including a charging pile body 1, a base 2, a protection plate 3 and a buffer assembly. Among them, the buffer assembly and the protection plate 3 are symmetrically arranged with the vertical center line of the charging pile body 1 as the axis of symmetry, which is convenient for protecting both sides. Positioning bolts are provided at the edge of the upper surface of the base 2 for convenient fixation.

[0028] As Figure 1As shown, the protection plate 3 is arc-shaped and is arranged on the surface of the buffer assembly in the manner of a sliding rod. The purpose of this setting is to facilitate the dispersion of the impact point and reduce the damage to the charging pile main body 1.

[0029] The charging pile main body 1 is fixedly connected to the upper surface of the base 2. The buffer assembly is arranged on both sides of the charging pile main body 1 to offset the impact force. The protection plate 3 is arranged on the surface of the buffer assembly. A connecting wire 4 and a limiting ring 5 are provided on the front surface of the charging pile main body 1. One end of the connecting wire 4 is fixedly connected to a charging gun 6, and one end of the charging gun 6 is inserted into the inside of the limiting ring 5.

[0030] The buffer assembly includes side plates 7 fixedly connected to both sides of the charging pile main body 1, shock-absorbing members arranged inside the side plates 7, buffer plates 8 fixedly connected to the ends of the shock-absorbing members away from the side plates 7, and roller one 9 and roller two 10 arranged at both ends of the buffer plate 8, and when used in cooperation with the protection plate 3.

[0031] As Figure 1 shown, when the protection plate 3 is slightly impacted, the protection plate 3 slides on the surfaces of the roller one 9 and the roller two 10, and the roller one 9 and the roller two 10 do not rotate; a protection pad is provided on the surface of the protection plate 3, which can slow down the impact force when initially contacting the impact object and protect itself at the same time;

[0032] The limiting ring 5 on the front surface of the charging pile main body 1 can protect and limit the charging gun 6, reducing the risk of detachment and damage during impact. A display screen is provided on the front surface of the charging pile main body 1 for convenient charging operation.

[0033] The existing charging piles have the following protection methods;

[0034] 1. Adopt a flexible anti-collision guardrail to form a safety barrier around it. When being impacted, the anti-collision guardrail contacts it first to reduce the damage to the charging pile;

[0035] 2. Increase the base of the charging pile and use impact-resistant materials, and these materials can maintain good integrity and stability when being impacted, thereby reducing the damage degree of the charging pile;

[0036] The disadvantages of the above two protection methods; Using a flexible anti-collision guardrail and impact-resistant materials results in higher manufacturing costs and installation costs, and cannot effectively disperse the force of impacting the charging pile main body.

[0037] The differences between this application and the existing protection methods are as follows;

[0038] The bottom of the charging pile body 1 is installed with the base 2 (not limited to installation by bolts or welding), which increases the stability of the charging pile body 1. Side plates 7 are provided on both sides of the charging pile body 1. A shock-absorbing member is provided on one side of the side plate 7, and a buffer plate 8 is fixedly connected through the shock-absorbing member. Then, a protective plate 3 is provided on the other side of the buffer plate 8; An auxiliary rod 30 is provided at the top of the side plate 7, and a detachable protective cover 31 is threadedly connected to the top of the auxiliary rod 30;

[0039] It should be noted that when an electric vehicle accidentally hits the charging pile body 1, it will first come into contact with the protective plate 3. The protective plate 3 will slide along the surface of the buffer plate 8, thereby dispersing the impact force. When the impact force is relatively large, the impact force will be transmitted to the buffer plate 8. At this time, the buffer plate 8 offsets the impact force through the shock-absorbing member. When the impact force is even greater, the impact force will be transmitted through the side plate 7 to the auxiliary rod 30 and the protective cover 31, further offsetting the impact force; Compared with the existing protection methods, when protecting the charging pile body 1, the impact force can be dispersed and the impact force can be offset at the same time, and the protection effect is good.

[0040] The shock-absorbing member includes a limiting cylinder 11 fixedly connected to the surface of the buffer plate 8 and a shock-absorbing spring 12 provided inside the limiting cylinder 11. Among them, the number of shock-absorbing members is several, which are evenly arranged on the side of the buffer plate 8 close to the side plate 7. One end of the shock-absorbing spring 12 is fixedly connected to the inside of the limiting cylinder 11, and the other end is fixedly connected to the inner bottom wall of the groove opened on the side plate 7; The end of the limiting cylinder 11 extending into the groove is slidably connected to its inner side wall.

[0041] A positioning component for limiting the first roller 9 and the second roller 10 is provided inside the side plate 7 and the buffer plate 8. The purpose of this setting is to reduce the sliding of the first roller 9 and the second roller 10 to assist the protective plate 3 during a slight impact.

[0042] The positioning component includes a gear rod 13 provided inside the side plate 7, a winding drum 14 meshed with the gear rod 13, and a fixing belt 15 fixedly connected to the surface of the winding drum 14.

[0043] A positioning rod 16 is fixedly connected to the end of the fixing belt 15 away from the winding drum 14. The positioning rod 16 is provided inside both ends of the buffer plate 8 and a return spring 17 is sleeved on its surface. The top and bottom ends of the first roller 9 and the second roller 10 are provided inside the top plate and the bottom plate of the buffer plate 8. Card slots 18 are opened on the outer walls of the tops of the first roller 9 and the second roller 10. One end of the positioning rod 16 extends into the inside of the card slot 18, and an auxiliary spring is sleeved on the end of the gear rod 13 away from the winding drum 14.

[0044] Such as Figure 6 and Figure 7As shown, when the impact force is transmitted to the buffer plate 8, the limiting cylinder 11 drives the shock-absorbing spring 12 inside it to move into the groove opened on the side of the side plate 7, thereby offsetting the impact force. When the impact force is relatively large, at this time, the shock-absorbing member in the middle of the top of the buffer plate 8 moves into the inside of the groove. When the limiting cylinder 11 presses the gear rod 13, the gear rod 13 contracts inward, synchronously driving the winding cylinder 14 to rotate, and part of the fixing belt 15 is wound on its surface. The other end of the fixing belt 15 drives the positioning rod 16 to move out of the inside of the card slot 18. When the limiting cylinder 11 passes over the gear rod 13, the gear rod 13 abuts against the outer wall of the limiting cylinder 11 by means of the auxiliary spring on its surface. At this time, one end of the positioning rod 16 will not reset inside the card slot 18, which facilitates the first roller 9 and the second roller 10 to assist the protection plate 3 to slide quickly, thereby reducing the damage to the charging pile body 1.

[0045] A fan blade 19 is provided at the bottom end of the second roller 10. A telescopic hose 20 is provided on the surface of the buffer plate 8 near the bottom end of the second roller 10. The other end of the telescopic hose 20 is fixedly connected to the upper surface of the base 2. An air flow chamber 21 communicated with the telescopic hose 20 is provided inside the base 2. When the buffer plate 8 approaches the side plate 7, it synchronously drives the telescopic hose 20 to perform synchronous telescopic movement.

[0046] An air outlet pipe 22 is fixedly connected to the front of the charging pile body 1 near the limiting ring 5. The bottom end of the air outlet pipe 22 is fixedly connected to the upper surface of the base 2 and communicated with the air flow chamber 21.

[0047] An annular airbag layer 23 is provided on the inner wall of the limiting ring 5 and is communicated with the air outlet pipe 22 and the air flow chamber 21. A one-way valve 24 is provided at the part of the air outlet pipe 22 near the limiting ring 5. A pressure relief valve 25 is provided on the surface of the limiting ring 5. A fixing cover (as shown in the figure, not labeled) is threadedly connected to the surface of the limiting ring 5 and is communicated with the annular airbag layer 23. When it is necessary to discharge the gas in the annular airbag layer 23, just open the fixing cover. Figure 3 As shown, when the second roller 10 rotates, it synchronously drives the fan blade 19 at its bottom to rotate. The air flow formed at this time passes through the telescopic hose 20, the air flow chamber 21 and the air outlet pipe 22 and enters the inside of the limiting ring 5 and the annular airbag layer 23, causing it to expand rapidly. An annular groove is provided on the outer wall of the charging gun 6. The expanded annular airbag layer 23 extends into the annular groove, which can quickly limit and protect the charging gun 6 and reduce the situation that the charging pile body 1 falls off due to excessive impact force;

[0048] As Figures 3 to 6 shown, when the annular airbag layer 23 expands to the set value, the pressure relief valve 25 will automatically open to prevent the annular airbag layer 23 from continuing to expand. The one-way valve 24 provided inside the air outlet pipe 22 can keep the air flow discharging into the annular airbag layer 23 unidirectionally and avoid the situation of backflow.

[0049] When the annular airbag layer 23 expands to the set value, the pressure relief valve 25 will automatically open to prevent the annular airbag layer 23 from continuing to expand. The one-way valve 24 provided inside the air outlet pipe 22 can keep the air flow discharging into the annular airbag layer 23 unidirectionally and avoid the situation of backflow.

[0050] As shown Figure 1 in FIG. [not provided], a protrusion is provided on the side of the buffer plate 8 away from the side plate 7, so that when the protection plate 3 is impacted, the impact force is transmitted to the protrusion part, which can not only increase the strength of the buffer plate 8, but also make the buffer plate 8 fit the protection plate 3;

[0051] Guide grooves 26 are provided at the top and bottom of the protection plate 3. A guide rail 27 is fixedly connected inside the top guide groove. A spring 28 is provided on the surface of the guide rail 27. One end of the top connecting rod of the buffer plate 8 is sleeved on the surface of the guide rail 27. A support rod 29 is fixedly connected to the side of the buffer plate 8 away from the side plate 7 at the bottom. The top end of the support rod 29 is arranged inside the bottom guide groove of the protection plate 3. An auxiliary plate 32 is fixedly connected to the side of the buffer plate 8 close to the side plate 7 at the top, which can protect the fixing belt 15 (made of nylon) to prevent the fixing belt 15 from being clamped in the middle when the buffer plate 8 quickly approaches the side plate 7.

[0052] As shown Figure 7 and Figure 9 in FIG. [not provided], a connecting rod is fixedly connected to the central part of the winding drum 14. The top end of the connecting rod penetrates through the inner top wall of the side plate 7 and extends to the outside. An auxiliary ring is fixedly connected to the top end of the connecting rod. When the shock absorber needs to be reset, rotate the auxiliary ring counterclockwise to drive the winding drum 14 to rotate, so that one end of the gear rod 13 contracts. At this time, the shock absorption spring 12 releases its compressed state, and simultaneously drives the limit cylinder 11 to move away from the gear rod 13. Then release the auxiliary ring, and the gear rod 13 is reset through the auxiliary spring;

[0053] A rubber pad is fixedly connected to the side of the buffer plate 8 close to the side plate 7. The purpose of this setting is to reduce the impact force of the buffer plate 8 on the side plate 7.

[0054] When the charging pile body 1 is slightly impacted, the protection plate 3 tilts the impact angle to reduce the damage to the charging pile body 1. When the protection plate 3 slides, the spring 28 on the surface of the guide rail 27 can slow down the sliding speed of the protection plate 3, reduce the impact force, and at the same time facilitate reset and repeated use.

[0055] In the present invention, the working steps of the device are as follows:

[0056] During use, when an electric vehicle driver accidentally hits the charging pile body 1, the protection plate 3 comes into contact with the impact part of the electric vehicle in advance. In the case of a slight impact, the impact is transmitted to the buffer plate 8 through the protection plate 3, and the shock absorber is used to offset the impact force. At the same time, the protection plate 3 can tilt the impact angle to reduce the impact force on the charging pile body 1. When the impact force is relatively large, while offsetting the impact force through the shock absorber, the limit on the first roller 9 and the second roller 10 is released. When the protection plate 3 presses against the first roller 9 and the second roller 10, it drives them to rotate and at the same time assists its own rapid sliding, quickly tilting the impact angle to reduce the damage to the charging pile body 1. When the impact force further increases, the auxiliary rod 30 at the top of the side plate 7 can drive the protective cover 31 to deform, further offsetting the impact force and reducing the damage to the charging pile body 1. When the second roller 10 rotates, it synchronously drives the fan blade 19 at its bottom to rotate, and the generated airflow enters the inside of the annular airbag layer 23, causing it to expand and contact the outer wall of the charging gun 6, reducing the risk of the charging gun 6 falling off when being hit and protecting it at the same time.

[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
