Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a safe charging pile and a method thereof. Background Art

[0002] Electric vehicle charging stations are most commonly categorized by installation location and charging method. Based on the installation location, they can be divided into public, dedicated, and private charging stations. Based on the charging method, they can be divided into slow charging, fast charging, and wireless charging.

[0003] There are many existing technologies for charging pile devices, such as:

[0004] Chinese patent publication number CN113978286A discloses an anti-collision structure and a charging pile with the structure, which relates to the field of charging piles and includes: a charging body, a protective part, and a rain shield. When the charging pile is hit by a vehicle or other factors, the protective plate of the protective device is first hit to prevent damage to the surface of the charging pile, and then cooperates with the first protective spring to apply a reverse force to the protective plate to further reduce the impact force on the protective plate. When the charging pile collapses due to excessive collision force, the second protective spring and the first protective spring support the protective plate to prevent the charging pile from being damaged after falling to the ground.

[0005] However, there are still some problems in actual use:

[0006] 1. When using existing charging piles, a protective plate is usually provided at the end of the charging pile. Since the charging pile body is directly exposed to the outside, when a vehicle drives to the charging pile for charging, the driver may easily cause it to directly hit the protective plate due to misoperation. When the impact force is too large, the protective plate and the charging pile will collide again, causing damage to the internal electrical components of the charging pile, affecting the normal use of the charging pile.

[0007] 2. Since it is fixed to the ground and difficult to move, the charging pile will directly bear the impact force, which can easily cause the charging pile to fall and be damaged. Usually, the charging pile is firmly installed on the ground to ensure its stability and safety. However, this fixing method makes it impossible for the charging pile to buffer the impact by moving when facing a large impact force, thereby increasing the risk of damage to the charging pile.

[0008] Therefore, a safe charging pile and method thereof are proposed. Summary of the Invention

[0009] The object of the present invention is to provide a safe charging pile and method thereof to solve the problems raised in the above background technology.

The baffle is subjected to external impact force to compress the buffer spring and at the same time push the gear rod to move inside the protective frame.

[0013] As a further improvement of this technical solution, a gear is provided on one side of the gear rod, which drives the gear to engage and rotate when the gear rod moves. A screw rod is provided on the surface of the gear, and a support plate is provided between the screw rods.

[0015] As a further improvement of the present technical solution, a fixed pulley is provided on the surface of the support plate, and a pull rope is provided at the end of the base plate. The pull rope is fixed to the bottom of the fixed pulley and is attached to the bottom of the fixed ear to control the distance between the support plate and the fixed ear, and can adjust the distance between the toothed block and the tooth pattern at the end of the elastic part.

[0016] As a further improvement of the present technical solution, when the charging pile body is placed on the surface of the support plate, in a natural state, the base plate is pulled away from the end of the elastic member by the pulling rope.

[0017] As a further improvement of the present technical solution, the protective assembly includes a three-way pipe arranged inside the protective frame, and a compression plug is provided at the end of the three-way pipe. The compression plug is fixed above the gear rod, and the gear rod is moved to drive the compression plug to compress the air inside the three-way pipe.

[0018] As a further improvement of the present technical solution, an air cushion is provided at the end of the three-way pipe. The width of the air cushion is greater than that of the screw rod. When the air cushion is inflated, the screw rod is protected to reduce deformation of the screw rod caused by impact.

[0019] A second object of the present invention is to provide a method for using a safe charging pile, comprising any one of the safe charging piles described above, comprising the following steps:

[0020] S1. Place the charging pile body between the slides by squeezing the slides. The slides are reset by the elastic force of the elastic member to limit the side wall of the charging pile body, thereby achieving rapid installation of the charging pile body.

[0021] S2. When the baffle is hit, the baffle drives the gear rod to move inside the protective frame. During the movement, the baffle squeezes the buffer spring. Since the buffer spring has elastic potential energy, it can buffer the external impact force, reduce the impact force of the vehicle on the protective frame, and avoid damage to the baffle due to excessive external impact force. At the same time, the baffle drives the gear rod to move in the axial direction. When the gear rod moves, it drives the gear to rotate. When the gear rotates, it drives the screw rod to rotate coaxially. A support plate is provided on the surface of the screw rod. Therefore, the support plate moves vertically upward on the surface of the screw rod, so that the support plate drives the charging pile body away from the impact point;

[0022] S3. When the protective frame is hit by an external impact, the long rod slides on the inner wall of the hollow column due to the impact force. The base plate at the end of the long rod drives the toothed block to move to the end of the slide. The toothed block clamps the end of the slide to limit the position of the slide. In the case of external shaking, the charging pile body clamped between the slides can be kept fixed.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In this safety charging pile, when a vehicle hits the baffle due to misoperation, the baffle drives the gear rod to move inside the protective frame. During the movement, the baffle squeezes the buffer spring. Since the buffer spring has elastic potential energy, it can buffer the external impact force, reduce the impact force of the vehicle on the protective frame, and avoid damage to the baffle due to excessive external impact force.

[0025] 2. In this safety charging pile, when the baffle is hit, the baffle drives the gear rod to move in the axial direction. When the gear rod moves, it drives the gear to rotate. When the gear rotates, it drives the lead screw to rotate coaxially. A support plate is provided on the surface of the lead screw. Therefore, the support plate moves vertically upward on the surface of the lead screw, so that the support plate drives the charging pile body away from the impact point, avoiding excessive impact force on the bottom of the charging pile body, which may cause damage to electrical components and improve the service life of the charging pile body.

[0026] 3. In this safety charging pile, when the protective frame is hit by an external impact, the long rod slides on the inner wall of the hollow column due to the impact force, and the base plate provided at the end of the long rod drives the toothed clamping block to move to the end of the slide. The end of the slide is clamped by the toothed clamping block to limit the slide. In the case of external shaking, the charging pile body clamped between the slides can be kept fixed, thereby preventing the charging pile body from falling and hitting the ground and being damaged, thereby improving the stability of the charging pile body.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, one of the purposes of the present invention is to provide a safe charging pile, see Figures 1-8 As shown, it includes a charging pile body 100, a protective frame 101 is provided on the outside of the charging pile body 100, fixing ears 103 are provided on both sides of the top of the protective frame 101, a heat dissipation hole 102 is provided at the bottom of the charging pile body 100, a support plate 200 is provided at the bottom of the charging pile body 100, and clamping components are provided on both sides of the support plate 200. The clamping component is used to limit the charging pile body 100 placed on the surface of the support plate 200, and a buffer component 300 is provided at the end of the protective frame 101. The buffer component 300 is used to buffer external impacts. At the same time, when the buffer component 300 is hit, the support plate 200 is driven to move up in the vertical direction, so that the charging pile body 100 placed on the surface of the support plate 200 is away from the impact range. A fixing component 400 is provided at the end of the clamping component. The fixing component 400 is used to automatically fix the clamping component during impact to improve the stability of the charging pile body 100. The inner wall of the protective frame 101 is provided with a protective component 500. The buffer component 300 inflates the inside of the protective component 500 during impact to protect the buffer component 300.

[0043] Taking into account that when the charging pile is in use, it is necessary to disassemble the charging pile body 100 and send it to the maintenance site when it is being repaired. In order to facilitate the rapid disassembly of the charging pile body 100, the clamping assembly includes a column 201 provided on both sides of the surface of the support plate 200. A slide plate 202 is provided on the inner wall of the column 201 for sliding. An elastic member 203 is provided between the column 201 and the slide plate 202. By pressing the slide plate 202 to slide on the inner wall of the column 201 to compress the elastic member 203, the charging pile body 100 is placed between the elastic members 203 for limiting. There are tooth patterns on both sides of the elastic member 203. 00 is being overhauled, the sliding plate 202 is squeezed by moving the charging pile body 100, so that the sliding plate 202 slides on the inner wall of the column 201 and squeezes the elastic member 203, so that the clamping force of the sliding plate 202 on the side wall of the charging pile body 100 is reduced, thereby facilitating the rapid disassembly of the charging pile body 100 to complete the overhaul. At the same time, when installing the charging pile body 100, the charging pile body 100 is placed between the sliding plates 202 by squeezing the sliding plate 202. The sliding plate 202 is reset by the force of the elastic member 203 to limit the side wall of the charging pile body 100, thereby achieving rapid installation of the charging pile body 100.

[0044] During the charging process of the vehicle, due to the different driving skills of the drivers, the charging pile body 100 is easily hit during the reversing process, causing damage to the equipment. Therefore, the buffer component 300 includes a gear rod 301 set on both sides of the end of the protective frame 101, a baffle 302 is provided at the end of the gear rod 301, and a buffer spring 303 is provided between the gear rod 301 and the baffle 302. The baffle 302 is in an arc shape. The baffle 302 is subjected to an external impact force to compress the buffer spring 303, and at the same time pushes the gear rod 301 to move inside the protective frame 101. By A protective frame 101 is provided to protect the charging pile body 100. When an external vehicle hits the protective frame 101, the baffle 302 blocks the vehicle. When the vehicle hits the baffle 302 due to misoperation, the baffle 302 drives the gear rod 301 to move inside the protective frame 101. The baffle 302 squeezes the buffer spring 303 during the movement. Since the buffer spring 303 has elastic potential energy, it can buffer the external impact force, reduce the impact force of the vehicle on the protective frame 101, and avoid damage to the baffle 302 due to excessive external impact force.

[0045] When the vehicle is misoperated, if the impact force is too large, it is easy to cause the protective frame 101 to deform, thereby impacting the bottom of the charging pile body 100 and causing damage to the electrical components inside the charging pile body 100, affecting the use of the charging pile body 100. Therefore, a gear 304 is provided on one side of the gear rod 301. When the gear rod 301 moves, it drives the gear 304 to engage and rotate. A screw rod 305 is provided on the surface of the gear 304. A support plate 200 is provided between the screw rods 305. When the gear 304 drives the screw rod 305 to rotate, the support plate 200 moves on the surface of the screw rod 305. When the vehicle hits the surface of the baffle 302, the baffle 302 drives the gear rod 301 to move in the axial direction. When the gear rod 301 moves, it drives the gear 304 to rotate. When the gear 304 rotates, it drives the screw rod 305 to rotate coaxially. A support plate 200 is provided on the surface of the screw rod 305. Therefore, the support plate 200 moves in the vertical upward direction on the surface of the screw rod 305, so that the support plate 200 drives the charging pile body 100 away from the impact point, avoiding the bottom of the charging pile body 100 from being subjected to excessive impact force, causing damage to electrical components, and improving the service life of the charging pile body 100.

[0046] When the external impact force is too large, the charging pile body 100 placed in the middle of the clamping assembly is prone to shaking. In order to improve the safety of the charging pile body 100 and prevent it from falling and causing safety hazards, the fixing assembly 400 includes a hollow column 401 arranged on one side of the elastic member 203. The inner wall of the hollow column 401 is provided with a long rod 402 for sliding. The end of the long rod 402 is provided with a base plate 404. Toothed card blocks 405 are provided on both sides of the base plate 404. The toothed card blocks 405 are engaged with the teeth at the end of the elastic member 203. The toothed card blocks 405 are moved to the end of the elastic member 203 to limit and fix it. A cooling fan 406 is provided on the surface of the base plate 404. When the protective frame 101 is subjected to external impact, the long rod 402 is subjected to the impact force. Sliding on the inner wall of the hollow column 401, the base plate 404 provided at the end of the long rod 402 drives the toothed block 405 to move to the end of the slide plate 202, and the toothed block 405 is used to clamp the end of the slide plate 202 to limit the slide plate 202. In the case of external shaking, the charging pile body 100 clamped between the slide plates 202 can be kept fixed, thereby improving the stability of the charging pile body 100, thereby preventing the charging pile body 100 from falling and hitting the ground and being damaged. At the same time, the cooling fan 406 is used to blow air to the heat dissipation hole 102 to improve the heat dissipation effect of the charging pile body 100, thereby preventing the internal temperature of the charging pile body 100 from being too high and affecting the charging speed when the charging load is too large, thereby improving the charging efficiency.

[0047] When there is an external impact, in order to improve the sensitivity of the toothed block 405 and make the toothed block 405 automatically limit and fix the slide plate 202, a fixed pulley 407 is provided on the surface of the support plate 200, and a pull rope 408 is provided at the end of the base plate 404. The pull rope 408 fits the bottom of the fixed pulley 407 and is fixed to the bottom of the fixed ear 103 to control the distance between the support plate 200 and the fixed ear 103. The distance between the toothed block 405 and the tooth pattern at the end of the elastic member 203 can be adjusted. When the charging pile body 100 is placed on the surface of the support plate 200, in a natural state, the base plate 404 is pulled away from the end of the elastic member 203 by the pull rope 408. When the baffle 302 is impacted by the external When a collision occurs, the baffle 302 drives the gear rod 301 to move and drives the gear 304 to rotate. The gear 304 drives the screw rod 305 to rotate coaxially. When the screw rod 305 rotates, it drives the support plate 200 to move in the vertical direction. When the support plate 200 moves, the pull rope 408 approaches the fixed ear 103, so that the pulling force of the pull rope 408 on the base plate 404 disappears. When the tension disappears, the long rod 402 at the end of the toothed block 405 is reset by the force of the compression spring 403, so that the toothed block 405 quickly moves to the end of the slide plate 202, so as to quickly limit the slide plate 202 and make the charging pile body 100 stably fixed between the support plates 200.

[0048] Taking into account that when the protective frame 101 is hit by a strong impact, the deformation of the protective frame 101 may easily cause the deformation of the screw rod 305 provided inside, thereby affecting the lifting and lowering of the support plate 200. Therefore, the protective component 500 includes a three-way pipe 501 arranged inside the protective frame 101, and a compression plug 502 is provided at the end of the three-way pipe 501. The compression plug 502 is fixed above the gear rod 301. The gear rod 301 is moved to drive the compression plug 502 to compress the air inside the three-way pipe 501. An air cushion 503 is provided at the end of the three-way pipe 501. The width between the air cushions 503 is greater than the screw rod 305. When the air cushion 503 is inflated, the screw rod 305 is protected. The protection frame 101 can protect the screw rod 305 and reduce the deformation caused by the impact. When the baffle 302 is subjected to the impact force, it drives the air plug 502 to move in the horizontal direction. When the air plug 502 moves, it squeezes the air inside the tee pipe 501. The air inside the tee pipe 501 is output from the middle pipe to the air cushion 503, so that the air is input into the air cushion 503 and expands. When the protective frame 101 is deformed, since the width of the air cushion 503 is greater than the screw rod 305, the screw rod 305 can be protected to avoid the screw rod 305 being deformed by the impact force and affecting the upgrade of the support plate 200, thereby improving the protection effect of the charging pile body 100.

[0049] When in use, the charging pile body 100 is placed between the slide plates 202 by squeezing the slide plate 202. The slide plate 202 is reset by the elastic member 203 to limit the side wall of the charging pile body 100, thereby realizing the quick installation of the charging pile body 100. When the vehicle hits the baffle 302 due to misoperation, the baffle 302 drives the gear rod 301 to move inside the protective frame 101. The baffle 302 squeezes the buffer spring 303 during the movement. Since the buffer spring 303 has elastic potential energy, it can buffer the external impact force, reduce the impact force of the vehicle on the protective frame 101, and avoid When the baffle 302 is damaged due to excessive external impact force, and the vehicle hits the surface of the baffle 302, the baffle 302 drives the gear rod 301 to move in the axial direction. When the gear rod 301 moves, it drives the gear 304 to rotate. When the gear 304 rotates, it drives the screw rod 305 to rotate coaxially. A support plate 200 is provided on the surface of the screw rod 305. Therefore, the support plate 200 moves vertically upward on the surface of the screw rod 305, so that the support plate 200 drives the charging pile body 100 away from the impact point, thereby preventing the bottom of the charging pile body 100 from being subjected to excessive impact force and causing damage to electrical components, thereby improving the service life of the charging pile body 100.

[0050] When the protective frame 101 is hit by an external impact, the long rod 402 slides on the inner wall of the hollow column 401 under the impact force, and the base plate 404 provided at the end of the long rod 402 drives the toothed clamping block 405 to move to the end of the slide plate 202. The toothed clamping block 405 clamps the end of the slide plate 202 to limit the position of the slide plate 202. In the case of external shaking, the charging pile body 100 clamped between the slide plates 202 can be kept fixed, thereby preventing the charging pile body 100 from falling and hitting the ground and being damaged, thereby improving the stability of the charging pile body 100.

[0051] When the baffle 302 is subjected to impact force, it drives the air compressor 502 to move in the horizontal direction. When the air compressor 502 moves, it squeezes the air inside the tee pipe 501. The air inside the tee pipe 501 is output from the middle pipe to the air cushion 503, so that the air is input into the air cushion 503 and expands. When the protective frame 101 is deformed, since the width of the air cushion 503 is greater than the screw rod 305, it can protect the screw rod 305 and prevent the screw rod 305 from being deformed by the impact force and affecting the upgrade of the support plate 200, thereby improving the protection effect of the charging pile body 100.

[0052] A second object of the present invention is to provide a method for using a safe charging pile, including any one of the above-mentioned safe charging piles, comprising the following steps:

[0053] S1. The charging pile body 100 is placed between the slides 202 by squeezing the slides 202. The slides 202 are reset by the elastic member 203 to limit the side wall of the charging pile body 100, thereby achieving rapid installation of the charging pile body 100.

[0054] S2. When the baffle 302 is hit, the baffle 302 drives the gear rod 301 to move inside the protective frame 101. During the movement, the baffle 302 squeezes the buffer spring 303. Since the buffer spring 303 has elastic potential energy, it can buffer the external impact force, reduce the impact force of the vehicle on the protective frame 101, and avoid damage to the baffle 302 due to excessive external impact force. At the same time, the baffle 302 drives the gear rod 301 to move in the axial direction. When the gear rod 301 moves, it drives the gear 304 to rotate. When the gear 304 rotates, it drives the screw rod 305 to rotate coaxially. A support plate 200 is provided on the surface of the screw rod 305. Therefore, the support plate 200 moves in the vertical upward direction on the surface of the screw rod 305, so that the support plate 200 drives the charging pile body 100 away from the impact point;

[0055] S3. When the protective frame 101 is hit by an external impact, the long rod 402 slides on the inner wall of the hollow column 401 due to the impact force, and the base plate 404 provided at the end of the long rod 402 drives the toothed block 405 to move to the end of the slide 202. The toothed block 405 clamps the end of the slide 202 to limit the position of the slide 202. In the case of external shaking, the charging pile body 100 clamped between the slides 202 can be kept fixed.

[0056] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
