Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and more specifically, to a high-speed charging pile that can be fully charged and automatically switched. Background Technology

[0002] In the manufacturing of facilities related to new energy vehicles, high-speed charging piles are key energy replenishment facilities for long-distance travel of new energy vehicles. Their core purpose is to replenish a large amount of range to the vehicle battery in a short time through high-power DC fast charging technology, thereby significantly alleviating users' range and time anxiety.

[0003] Among existing published documents, patent publication number CN117863935A discloses an intelligent charging pile based on a highway service area. This technology involves accumulating objects on the surface of a reflective convex plate and pressing it against a symmetrical weight plate. When the weight of the objects exceeds the maximum load-bearing capacity, the stacking and flipping frame flips to a vertical angle, causing the objects on the stacking and flipping frame to slide off. This automatically cleans up the impurities accumulated on the top of the charging pile, reducing the load-bearing burden on the charging pile and extending its service life. However, this technology still has the following problems.

[0004] When charging new energy vehicles, the charging gun needs to be inserted into the vehicle's charging port. However, during the charging process, there are instances where people forcibly unplug the charging gun before it is fully charged and without the owner's consent. This not only stops the charging but also causes charging disputes. Therefore, it is difficult to implement multi-dimensional anti-pull-out operations on the side, inner wall, and corners of the charging gun when it is not fully charged. Similarly, it is difficult to automatically implement multi-dimensional safe pull-out operations after it is fully charged. This makes it difficult for the charging station to flexibly switch between multi-dimensional anti-pull-out and safe pull-out operations based on the charging status, resulting in poor usability of the charging station. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a fully charged self-switching high-speed charging pile, including a charging host, wherein a charging gun is provided on one side of the charging host;

[0020] The displacement rope is fixed at its bottom end to one side of the inclined sleeve block, and the top end of the displacement rope is fixedly connected to the linkage block.

[0021] A sleeve is slidably connected to the outer wall of the displacement rope. The sleeve is fixedly connected to the charging gun. A guide post is slidably connected to the inner wall of the inclined sleeve block, and the guide post is fixedly connected to the inclined frame.

[0022] A groove block is located on one side of the guide post. The groove block is fixedly connected to the inclined frame, and the inner wall of the groove block is slidably connected to the displacement rope.

[0023] The spring bar is located on the other side of the guide post, and the inclined sleeve block and the inclined frame are both fixedly connected to the spring bar;

[0024] Multiple internal toothed cones are fixed to the inner wall of the internal toothed plate.

[0025] In a preferred embodiment, the upper surface of the sleeve is higher than the upper surface of the groove block, and the upper surface of the inclined sleeve block is parallel to the upper surface of the groove block.

[0026] In a preferred embodiment, the corner switching component includes:

[0028] A guide groove is formed above the corner toothed plate. The guide groove is used to guide the corner toothed plate to slide. A guide bar is fixed to the top of the pressing frame.

[0031] A linear servo is installed on one side of the linkage block. The retractable end of the linear servo is fixedly connected to the linkage block, and the outer wall of the linear servo is fixedly connected to the charging gun.

[0033] A current sensor is installed at the bottom of the charging host. One end of the current sensor is connected to a charging cable. The charging host and the charging gun are both fixedly connected to the charging cable. The charging host and the current sensor are electrically connected.

[0034] The technical effects and advantages of the present invention.

[0035] 1. This invention employs a side switching component, an internal switching component, and a corner switching component. During charging, the side tooth cone on the side tooth plate, the internal tooth cone on the internal tooth plate, and the corner tooth cone on the corner tooth plate are simultaneously exposed, forming a multi-dimensional anti-pull-out state. The stinging sensation effectively prevents abnormal gun pulling. After full charging, the linkage block, driven by the drive unit, drives the side tooth plate, internal tooth plate, and corner tooth plate to retract into the gun body, simultaneously releasing the multi-dimensional anti-forced pull-out state. The charging pile can flexibly switch between multi-dimensional anti-pull-out and multi-dimensional safe pull-out operations according to the charging status, greatly improving the flexibility of the charging pile.

[0036] 2. When the current sensor detects that the charging current has reached a preset value, the charging host controls the linear servo to move. Through the linkage block, the steel cable and the displacement cable are pulled synchronously, driving the side tooth plate, inner tooth plate and corner tooth plate to retract into the charging gun. The charging gun can be intuitively indicated without manual intervention, which significantly improves the intelligence and efficiency of the charging pile.

[0037] 3. This invention employs the coordinated operation of the side switching component, the internal switching component, and the corner switching component. This allows the sliding sleeve to slide along the guide rod, ensuring the stable translation of the side toothed plate. The inclined sleeve block moves obliquely along the guide post within the inclined frame to accommodate the inner toothed plate. The pressing frame connects to the sliding sleeve via the guide bar and the moving bar, causing the corner toothed plate to move synchronously with the side toothed plate. All components move collaboratively under the drive of the linkage block, ensuring consistent retraction and extension of the multi-dimensional anti-pull-out structure, improving the efficiency of switching the multi-dimensional anti-pull-out structure, and achieving efficient and flexible switching.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings.

[0050] Example 1:

[0051] like Figures 1-9 The illustrated high-speed charging pile with self-switching charging capability includes a charging host 1, a charging gun 2 on one side of the charging host 1; side toothed plates 3 slidably connected to both sides of the charging gun 2, and a side switching component installed between the two side toothed plates 3; an inner toothed plate 4, sliding on one side of the inner wall of the charging gun 2, and an internal switching component installed on the inner toothed plate 4; two corner toothed plates 5, each located on one side of the inner toothed plate 4, and corner switching components installed on the corner toothed plates 5; a linkage block 6, disposed between the two side toothed plates 3, and a drive unit installed on one side of the linkage block 6; and a detection unit installed at the bottom of the charging host 1.

[0052] In this embodiment, the charging gun 2 is inserted into the charging port of a new energy vehicle. When the detection unit detects that the charging is not fully charged, the side toothed plate 3, the inner toothed plate 4, and the corner toothed plate 5 form a multi-dimensional anti-pull-out operation from the side, inner wall, and corner of the charging gun 2, preventing the charging gun 2 from being forcibly pulled out abnormally. When the detection unit detects that the charging is fully charged, it triggers the drive unit to drive the linkage block 6 to move. The linkage block 6 drives the side switching component to drive the two side toothed plates 3 to move closer to each other and into the charging gun 2 until the two side toothed plates 3 are housed inside the charging gun 2. At the same time, the linkage block 6 drives the connected internal switching component to move. The internal switching component drives the inner toothed plate 4 into the interior of the charging gun 2 to form a protective area. The side switching component drives the corner switching component, and the corner switching component drives the corner toothed plate 5 into the interior of the charging gun 2 to realize the housing operation. The multi-dimensional anti-forced pull-out state is released simultaneously. At this time, there is no anti-pull-out structure on the charging gun 2, and the charging gun 2 can be easily and safely pulled out.

[0053] Example 2:

[0054] In this embodiment, as Figures 3-5 As shown, the side switching component includes: two steel ropes 7, installed between two side toothed plates 3, each steel rope 7 being fixedly connected to one side toothed plate 3 respectively, and both steel ropes 7 being fixedly connected to the linkage block 6. A sleeve plate 8 is slidably connected to the outer wall of each steel rope 7, and the sleeve plate 8 is fixedly connected to the charging gun 2; a spring plate 9, positioned above the linkage block 6, with both side toothed plates 3 fixedly connected to the spring plate 9, which provides elastic force to the two side toothed plates 3. Multiple side toothed cones 10 are fixed to one side of each side toothed plate 3; a sliding sleeve 13, fixedly connected to one end of the side toothed plate 3, with a support frame 11 connected to the outer wall of the sliding sleeve 13, which is fixedly connected to the charging gun 2. The support frame 11 guides the sliding sleeve 13 to slide. The side switching component is connected to the corner switching component. The two side toothed plates 3 are symmetrically arranged about the sleeve plate 8, and both steel ropes 7 are slidably connected to the support frame 11.

[0055] In this embodiment, as Figure 5 As shown, a guide rod 12 passes through the inner wall of the sliding sleeve 13. The guide rod 12 is fixedly connected to the support frame 11, and both sliding sleeves 13 are slidably connected to the guide rod 12. By sliding the sliding sleeves 13 simultaneously along the outer wall of the guide rod 12, the sliding sleeves 13 can be made to slide stably.

[0056] In this embodiment, when the detection unit detects that the charging is not fully charged, the two side tooth plates 3 are still located on both sides of the charging gun 2. Thus, the multiple side tooth cones 10 on the side tooth plates 3 provide multi-point protection. When the charging gun 2 is forcibly pulled out, the hand contacts the multiple side tooth cones 10 on the side tooth plates 3. At this time, the multiple side tooth cones 10 can produce a stinging sensation on the hand. The more force is applied, the stronger the pain sensation becomes, thus preventing the charging gun 2 from being forcibly pulled out abnormally.

[0057] When the detection unit detects that the charging is fully charged, the linkage block 6 drives the ends of the two steel ropes 7 to move synchronously to the left. The two steel ropes 7 slide along the inner wall of the sleeve plate 8, thereby pulling the side toothed plates 3, causing the two side toothed plates 3 to move closer to each other. The two side toothed plates 3 begin to squeeze the spring piece 9, so that the spring piece 9 provides elastic force to the two side toothed plates 3. At the same time, the side toothed plates 3 drive the sliding sleeve 13 to slide along the inner wall of the support frame 11. The sliding sleeve 13 also slides along the outer wall of the guide rod 12. In this way, the two sliding sleeves 13 move closer to each other, and the two side toothed plates 3 begin to move into the charging gun 2 for storage. This releases the multi-dimensional anti-pull-out state on both sides of the charging gun 2, so that other charging personnel can see and know that the charging gun 2 can be pulled out for use. It also makes it more intuitive to know that the charging gun 2 can be pulled out.

[0058] Example 3:

[0059] In this embodiment, as Figures 4-7 As shown, the internal switching components include: a slanted sleeve block 14, fixedly connected to the inner toothed plate 4, with an inclined frame 15 installed on the outer wall of the slanted sleeve block 14, the inclined frame 15 being fixedly connected to the charging gun 2, and the inclined frame 15 being used to guide the sliding of the slanted sleeve block 14; a displacement rope 16, the bottom end of which is fixed to one side of the slanted sleeve block 14, and the top end of the displacement rope 16 being fixedly connected to the linkage block 6; and a sleeve 17, slidably connected to the outer wall of the displacement rope 16, the sleeve 17 being connected to the charging gun 2. The inclined sleeve 14 is fixedly connected to the inner wall of the inclined frame 15, and the guide post 18 is slidably connected to the inner wall of the inclined frame 15. The groove block 19 is located on one side of the guide post 18 and is fixedly connected to the inclined frame 15. The inner wall of the groove block 19 is slidably connected to the displacement rope 16. The elastic bar 20 is located on the other side of the guide post 18, and both the inclined sleeve 14 and the inclined frame 15 are fixedly connected to the elastic bar 20. Multiple internal tooth cones 21 are fixed to the inner wall of the internal tooth plate 4. The upper surface of the sleeve 17 is higher than the upper surface of the groove block 19, and the upper surfaces of the inclined sleeve 14 and the groove block 19 are parallel to each other.

[0060] In this embodiment, when the detection unit detects that the charging is not fully charged, the inner tooth plate 4 is located in the inner wall area of ​​the charging gun 2. When the hand touches the inner tooth plate 4, it will be contacted by multiple inner tooth cones 21 on the inner tooth plate 4. Forced force will cause hand pain. This forms a protective area on the inner wall of the charging gun 2, preventing the charging gun 2 from being forcibly removed abnormally.

[0061] When the detection unit detects that the charging is fully charged, the linkage block 6 will pull the displacement rope 16. The displacement rope 16 slides along the inner wall of the sleeve 17 and slides along the inner wall of the slot block 19. The charging gun 2 supports the inclined frame 15, and the inclined frame 15 supports the guide post 18. In this way, the displacement rope 16 pulls the inclined sleeve block 14, and the inclined sleeve block 14 tilts and moves to the left along the outer wall of the guide post 18. At the same time, the inclined sleeve block 14 drives the inner tooth plate 4 to tilt and move to the left. The inner tooth plate 4 drives multiple inner tooth cones 21 to tilt and move to the left. In this way, the inner tooth plate 4 enters the internal position of the charging gun 2, realizing the storage operation of the inner tooth plate 4 and releasing the multi-dimensional anti-pull-out state of the inner wall of the charging gun 2. Other charging personnel can see this and know that the charging gun 2 can be pulled out directly for use. Moreover, it is more intuitive to know that the charging gun 2 can be pulled out.

[0062] Example 4:

[0063] In this embodiment, as Figures 4-9 As shown, the corner switching component includes: a pressing shaft 25, fixedly connected to one end of the corner toothed plate 5; a pressing frame 24 slidably connected to the outer wall of the pressing shaft 25, and the pressing frame 24 slidably connected to the charging gun 2; multiple corner toothed cones 26 fixedly connected to the lower surface of the corner toothed plate 5; a guide groove 27, opened above the corner toothed plate 5, for guiding the corner toothed plate 5 to slide; a guide bar 23 fixed to the top of the pressing frame 24; a moving bar 22 connected to the top of the guide bar 23; and both the guide bar 23 and the sliding sleeve 13 are fixedly connected to the moving bar 22. The guide groove 27 and the corner toothed plate 5 are both inclined, and the two corner toothed plates 5 are symmetrically arranged about the charging gun 2.

[0064] In this embodiment, when the detection unit detects that the charging is not fully charged, the multiple corner toothed cones 26 on the corner toothed plate 5 are located at the corner of the charging gun 2. This way, when the hand is holding the corner area of ​​the outer wall of the charging gun 2, it will come into contact with the multiple corner toothed cones 26. The more it is forcibly pulled out, the more painful it will be, thus avoiding forcibly pulling it out and preventing the charging gun 2 from being abnormally and forcibly removed.

[0065] When the detection unit detects that the charging is fully charged, the two sliding sleeves 13 move closer to each other, causing the two moving strips 22 to move closer simultaneously. The two moving strips 22 drive the two guide strips 23 to move closer to each other, and the two guide strips 23 slide along the charging gun 2. The two guide strips 23 drive the two pressing frames 24 to move closer to each other, and the pressing frames 24 press the pressing shaft 25. The pressing shaft 25 begins to tilt upward, and at the same time, the pressing shaft 25 drives the corner toothed plate 5 to tilt upward. The corner toothed plate 5 drives multiple corner toothed cones 26 to tilt upward, and at the same time, the corner toothed plate 5 begins to be stored inside the charging gun 2, releasing the corner multi-dimensional anti-pull-out state of the charging gun 2. Other charging personnel can see this and directly pull out the charging gun 2 for use. Moreover, it is more intuitive to know that the charging gun 2 can be pulled out, and it is convenient to hold the charging gun 2 on the outer wall of the hand to pull out the charging gun 2.

[0066] In this embodiment, as Figures 1-4 As shown, the drive unit includes a linear servo 30, mounted on one side of the linkage block 6. The retractable end of the linear servo 30 is fixedly connected to the linkage block 6, and the outer wall of the linear servo 30 is fixedly connected to the charging gun 2. The detection unit includes a current sensor 29, located at the bottom of the charging host 1. One end of the current sensor 29 is connected to a charging cable 28. Both the charging host 1 and the charging gun 2 are fixedly connected to the charging cable 28, and the charging host 1 is electrically connected to the current sensor 29.

[0067] In this embodiment, the charging gun 2 is inserted into the charging port of the new energy vehicle. The charging host 1 transmits the charging current to the charging gun 2 through the charging cable 28 to power the charging gun 2. In this way, the charging gun 2 can achieve high-power DC fast charging and enable the charging operation of the new energy vehicle.

[0068] After charging, the charging current of the charging cable 28 is detected by the current sensor 29. When the charging current does not reach the full charge current of the charging host 1, it is in an incomplete state. In this way, the side tooth plate 3, the inner tooth plate 4, and the corner tooth plate 5 form a multi-dimensional anti-pull-out operation from the side, inner wall, and corner position of the charging gun 2. Other non-charging vehicle owners cannot forcibly pull out the charging gun 2. This avoids the problem of the traditional charging gun 2 being damaged by forcibly pulling even though there is a locking mechanism. This technology will not have such a problem of forced pull-out.

[0069] The charging cable 28 is current-detected by the current sensor 29. When the detected current is the same as the current value when the charging host 1 is fully charged, the charging host 1 activates the linear servo 30, causing the retracting end of the linear servo 30 to drive the linkage block 6 to move to the left. In this way, the charging vehicle owner's mobile phone can be wirelessly connected to the charging host 1, thereby automatically controlling the left movement of the linkage block 6. The multi-dimensional anti-forced unplugging state can be synchronously released immediately after the battery is fully charged, making it convenient for other vehicle owners to intuitively know that charging is finished and that they can unplug the charging gun 2 to start charging.

[0070] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
