Description

Technical Field

[0001] The present invention belongs to the technical field of charging piles and relates to a charging pile for new energy vehicles. Background Art

[0002] A charging pile is an energy replenishment device that provides power replenishment for new energy vehicles. Its function is similar to that of a fuel dispenser in a gas station and can be fixed on the ground or wall and installed in public buildings and parking lots of residential communities.

[0003] A new type of charging pile disclosed in Chinese Patent CN114475323B adopts a cable wound on a winding base. A first main wire guide is provided through the surface of the charging pile housing; a fixing rod is provided inside the charging pile housing, and a secondary wire guide is provided on the fixing rod. The cable sequentially passes through the secondary wire guide and the first main wire guide and extends out of the charging pile housing, and a charging plug is connected to the end of the cable. A driving mechanism capable of recovering the cable when the charging plug falls off is provided on the side of the winding base. When the charging plug is separated from the cable, the electrical control box can detect the corresponding signal, cut off the power of the cable, perform a braking operation on the winding base through the driving mechanism, and further control the winding base to reverse and recover the cable.

[0004] After the charging pile controls the winding base to reverse and recover the cable, the charging plug at the end of the cable is still located outside the charging pile housing, so that the charging plug is easily collided and knocked when exposed outside for a long time, or its service life is reduced due to environmental influences such as rain and sun exposure.

[0005] To solve the above problems, the present invention proposes a charging pile for new energy vehicles. Summary of the Invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The new energy vehicle charging pile is provided with a protective cover, which is rotatably connected to the outside of the charging pile main body. After the cable is used up, the cable is wound by rotating the wire winding base, and the fixed plate will move along with the cable. When the fixed plate moves into the protective cover, the fixed plate will abut against the guide rod, causing the connecting piece to slide inside the charging pile main body, driving the sliding block, the first spring, and the limiting rod to move, so that the arc end of the limiting rod leaves the ratchet. At this time, the rotation of the ratchet is no longer restricted, so that the protective cover rotates downward under the action of gravity, and then the protective cover covers the charging plug, playing a role in protecting the charging plug.

[0029] 2. The new energy vehicle charging pile is provided with a limiting rod. When the charging plug needs to be used, the protective cover is rotated upward to make the protective cover leave the charging plug. At the same time, it will also drive the ratchet to rotate. When the ratchet rotates, it will push the limiting rod to slide. When the protective cover stops rotating, the arc end of the limiting rod will be stuck between two teeth on the ratchet, restricting the rotation of the ratchet, and then fixing the position of the protective cover. It can automatically fix the protective cover, facilitating subsequent charging and making use more convenient.

[0030] 3. The new energy vehicle charging pile is provided with a baffle. When in use on a sunny day, the baffle is driven by a driving component to rotate away from the filter screen, enabling ventilation of the charging pile main body through the filter screen, and the second motor can be used to drive the fan blades to rotate to make the ventilation effect better; when in use on a rainy day, the baffle can be rotated to the filter screen to seal the filter screen.

[0031] 4. The new energy vehicle charging pile is provided with a buffer plate. When the vehicle moves towards the charging pile main body, if the vehicle accidentally collides with the charging pile main body, it will first contact the buffer plate. The buffer plate will push the sliding rod to slide into the charging pile main body and stretch the fifth spring, achieving the purpose of buffering and playing a role in protecting the charging pile main body.

Detailed implementation manners

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] As Figures 1 - 16 shown, the technical solution adopted by the present invention is as follows: A new energy vehicle charging pile includes a charging pile main body 1. A fixing seat 7 is fixedly connected to the bottom surface of the charging pile main body 1.

One end of the winding shaft is rotatably connected to the inner wall of the charging pile main body 1, and the other end of the winding shaft is rotatably connected to the third fixing plate 30. A first motor 25 is fixedly connected to one side of the third fixing plate 30, and the first motor 25 drives the winding shaft to rotate.

[0054] One end of the cable 19 passes through the side surface of the charging pile main body 1 and extends to the outside of the charging pile main body 1.

[0055] A first through hole is opened on the side surface of the charging pile main body 1. An annular guiding block 18 is fixedly connected inside the first through hole. A number of rolling balls 31 are rotatably arranged on the inner wall of the guiding block 18, and the number of rolling balls 31 is circumferentially arranged about the guiding block 18. The cable 19 passes through the guiding block 18, and the cable 19 is slidably arranged between the rolling balls 31. The cable 19 will slide between the rolling balls 31, and the rolling balls 31 make the cable 19 smoother when passing through the guiding block 18, reducing friction.

[0056] A rubber ring 33 is attached to the side of the guiding block 18 away from the inner wall of the charging pile main body 1, and the cable 19 slidably penetrates through the rubber ring 33. When the cable 19 moves, the rubber ring 33 can scrape off impurities on the outer surface of the cable 19. Meanwhile, the sealing effect at the first through hole is improved.

[0057] A protective cover 4 is rotatably arranged at the charging pile main body 1 through which a cable 19 passes. A U-shaped handle 5 is fixedly connected to the protective cover 4.

[0058] Two symmetrical connecting plates 20 are fixedly connected to the charging pile main body 1 at the position of the protective cover 4, and the connecting plates 20 are fixedly connected to the outer side surface of the charging pile main body 1.

[0059] Cover plates 2 are fixedly connected to the outer side surface of the charging pile main body 1 at the positions of the connecting plates 20. The cover plates 2 are in a shape of a cover, and both ends of the rotating shaft are respectively rotatably connected to the corresponding cover plates 2. Positioning components are arranged inside the cover plates 2, and the positioning components together fix the position of the protective cover 4.

The other end of the limiting rod 15 is in an arc shape, and the arc end of the limiting rod 15 is clamped between two teeth of the ratchet wheel 3. When the ratchet wheel 3 rotates, it will push the limiting rod 15 to slide relatively in the horizontal direction.

[0063] Sealing plates 52 are fixedly connected to the sliding blocks 17. The sealing plates 52 close the notch of the first sliding groove 23 where the sliding blocks 17 are located and are in sliding fit with the outer surface of the charging pile main body 1. The length of the sealing plates 52 is greater than twice the length of the first sliding groove 23, so that when the sliding blocks 17 slide, the sealing plates 52 always seal the first sliding groove 23, thereby increasing the sealing effect on the charging pile main body 1.

[0064] Second fixing plates 22 are fixedly connected to the inner wall of the charging pile main body 1 at the positions of the first sliding grooves 23, and second springs 21 are fixedly connected between the sliding blocks 17 and the corresponding second fixing plates 22.

[0065] Two transmission components are symmetrically arranged on the charging pile main body 1, and both transmission components cooperate with the cable 19. When the wire winding base 28 rotates, the transmission components together drive the protective cover 4 to rotate.

[0070] The driving component includes an electric push rod 43, and the electric push rod 43 is fixedly connected to the inner wall of the charging pile main body 1. A fifth fixing plate 42 is fixedly connected to the inner wall of the charging pile main body 1, and the top end of the electric push rod 43 is fixedly connected to the bottom surface of the fifth fixing plate 42.

A fan blade 37 is fixedly connected to the end of the output shaft of the second motor 38. The fan blade 37 and the second through hole are corresponding front and back in the horizontal direction. When the fan blade 37 rotates, the wind generated will blow towards the second through hole, making the ventilation effect better.

[0073] A sliding rod 26 slidably penetrates through the side surface of the charging pile main body 1. The sliding rod 26 is a rectangular block. A fifth spring 27 is fixedly connected between the end of the sliding rod 26 extending into the charging pile main body 1 and the inner wall of the charging pile main body 1.

[0085] Working principle:

[0086] Use bolts to pass through the mounting holes on the fixing base 7 to fix the fixing base 7, and then install the charging pile main body 1. After installation, the buffer plate 8 faces the parking space.

[0087] During use, move the new energy vehicle to be charged to the charging pile main body 1. When the new energy vehicle is moving, if it accidentally touches the buffer plate 8, the buffer plate 8 will move towards the side close to the charging pile main body 1. Make the sliding rod 26 slide into the interior of the charging pile main body 1 and stretch the fifth spring 27. The fifth spring 27 has a buffering effect on the buffer plate 8.

[0088] When the buffer plate 8 moves, it will push the first sliding plate 10 through the connecting rod 9, and the first sliding plate 10 slides towards the side away from the buffer plate 8. The first sliding plate 10 will move closer to the corresponding second sliding plate 11 until the first sliding plate 10 contacts the corresponding second sliding plate 11.

[0089] The first sliding plate 10 will together push the second sliding plate 11 towards the corresponding first fixing plate 12 to slide, and the second sliding plate 11 will compress the sixth spring 13 to buffer again. Thus, it has a protective effect on the charging pile main body 1.

[0090] When the new energy vehicle leaves the buffer plate 8, the contraction of the fifth spring 27 will pull the sliding rod 26 to slide, and the sixth spring 13 will elongate to push the second sliding plate 11 and the first sliding plate 10. Then the buffer plate 8 will pull the first sliding plate 10 through the connecting rod 9, and the first sliding plate 10 will gradually move away from the second sliding plate 11 until it returns to its original state.

[0091] After moving the new energy vehicle to a suitable position. Rotate the protective cover 4 upward through the handle 5, so that the rotating shaft rotates on the connecting plate 20, and the two ends of the rotating shaft rotate on the corresponding cover plates 2 respectively, driving the ratchet wheel 3 to rotate.

[0092] When the ratchet wheel 3 rotates, it will push the limit rod 15. The limit rod 15 will slide on the corresponding slider 17 and compress the first spring 16. At this time, the thrust of the first spring 16 is not sufficient to overcome the elastic force of the second spring 21 to make the slider 17 slide. Therefore, the slider 17 will not slide on the first chute 23, and the sealing plate 52 will not slide either. As the ratchet wheel 3 rotates, under the action of the elastic force of the first spring 16, the limit rod 15 will be continuously pushed towards the ratchet wheel 3, so that the limit rod 15 is always in contact with the ratchet wheel 3.

[0093] After rotating the protective cover 4 to an appropriate angle, stop rotating the protective cover 4. At this time, under the action of the elastic force of the first spring 16, the limit rod 15 will be pushed, and the arc end of the limit rod 15 will be stuck between two teeth of the ratchet wheel 3. The ratchet wheel 3 is fixed. Furthermore, the position of the protective cover 4 is fixed.

[0094] Hold the charging plug 14 by hand and start the first motor 25. The output shaft of the first motor 25 rotates forward. Drive the wire winding base 28 to rotate, and gradually wind the cable 19 on the wire winding base 28 away. Pull the charging plug 14 outwards so that the cable 19 passes through the rubber ring 33 and the guide block 18. The cable 19 will slide on the ball 31, causing the ball 31 to roll and gradually wind the cable 19 out of the charging pile main body 1. At the same time, the fixed disk 29 will also leave the guide rod 51.

[0095] The charging pile main body 1 controls the power connection to the cable 19 to make the wire 50 energized. At this time, the electromagnet 49 is energized to generate magnetism and attract the moving plate 54, so that the moving plate 54 slides inside the receiving groove 53 and compresses the fourth spring 48. Until the moving plate 54 fits with the electromagnet 49, at this time, the ejector rod 47 is located inside the receiving groove 53. One end of the charging plug 14 can be inserted into the charging port of the new energy vehicle for charging through the wire 50.

[0096] During the charging process, if it is sunny, start the electric push rod 43. The telescopic rod at the output end of the electric push rod 43 extends downward, which will push the rack 41 downward. The rack 41 drives the gear 40 to rotate. Make the baffle 6 rotate, drive the rubber ring 33 and the brush 35 to rotate until the baffle 6 is rotated away from the filter screen 36.

[0097] At this time, ventilation can be carried out inside the charging pile main body 1 through the filter screen 36, and the filter screen 36 can filter impurities in the air. It is also possible to start the second motor 38 to make the fan blade 37 rotate, and the fan blade 37 blows air towards the filter screen 36 to further improve the ventilation effect. During ventilation, the baffle 6 can be driven to rotate reciprocally by the electric push rod 43, so that the brush 35 scrapes off the impurities on one side of the filter screen 36.

[0098] If it is rainy during the charging process, the electric push rod 43 pulls the rack 41 upward, causing the baffle 6 to rotate until the baffle 6 rotates to the filter screen 36 to block the second through hole. Similarly, the rubber ring 33 seals the second through hole to reduce the entry of rainwater.

[0099] After the charging is completed, unplug the charging plug 14 from the charging port of the new energy vehicle. Start the first motor 25, and the output shaft of the first motor 25 rotates in reverse. Drive the wire winding seat 28 to rotate, so that the cable 19 winds around the wire winding seat 28. Drive the fixed disk 29 to move towards the outer side of the charging pile main body 1.

[0100] The charging plug 14 will move towards the protective cover 4, and the fixed disk 29 will contact the guide rod 51 and push the guide rod 51 to slide into the charging pile main body 1. Drive the connecting piece 24 to slide inside the charging pile main body 1, and the sliding block 17 slides towards the side close to the second fixing plate 22 inside the first sliding groove 23, and the sealing plate 52 slides on the outer surface of the charging pile main body 1.

[0101] The sliding block 17 will compress the second spring 21 and drive the first spring 16 and the limiting rod 15 to move, so that the arc end of the limiting rod 15 leaves the ratchet wheel 3. At this time, the rotation of the ratchet wheel 3 is no longer restricted, so that the protective cover 4 rotates downward under the action of gravity, and then the protective cover 4 covers the charging plug 14, playing a protective role for the charging plug 14.

[0102] After the protective cover 4 stops on one side of the charging pile main body 1, the first motor 25 stops. Since the first motor 25 does not have a brake device, it does not have self-locking. The reset effect of the second spring 21 on the connecting piece 24 will push the cable 19 to move a short distance towards the outside of the charging pile main body 1, and the limiting rod 15 can be reset through the second spring 21 to lock the ratchet wheel 3.

[0103] If the charging plug 14 is forgotten to be unplugged after charging, the new energy vehicle will move the charging plug 14 away together. When pulling the charging plug 14, since one end of the cable 19 is located on the wire winding seat 28, when it is pulled to the limit length, the collar 44 will squeeze the block 46. Make the block 46 slide into the groove and compress the third spring 45 until one end of the charging plug 14 leaves the collar 44.

[0104] The wire 50 will leave the cable 19, cutting off the power supply of the wire 50. As a result, the electromagnet 49 is powered off and its magnetism disappears, no longer attracting the moving plate 54. Under the action of the elastic force of the fourth spring 48, the moving plate 54 will be pushed to slide towards the side away from the electromagnet 49, causing the ejector rod 47 to slide out of the receiving groove 53. One end of the charging plug 14 leaves the charging port of the new energy vehicle. During the movement of the new energy vehicle, the ejector rod 47 disengages from the new energy vehicle and drops. This prevents the charging plug 14 that prevents the cable 19 from disconnecting from being taken away by the energy vehicle and being difficult to find, resulting in losses.

[0105] The charging plug 14 is made of impact-resistant materials such as rubber and soft plastic. This enables the charging plug 14 to continue to be used after dropping, reducing losses.

[0106] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
