Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a high-performance tensile charging pile for new energy vehicles. Background Art

[0002] The development of new energy vehicles and charging piles has a profound impact on the world's development. It plays an important role in promoting the transformation of the global energy structure, environmental protection, and economic growth, helping to reduce dependence on traditional fossil fuels and promoting the transformation of the global energy structure. New energy vehicle charging piles are important infrastructure for the development of the new energy vehicle industry, which can provide necessary electrical energy replenishment for electric vehicles, enabling electric vehicles to continue driving, solving the problem of limited driving range of electric vehicles, reducing users' range anxiety about electric vehicles, and thus promoting the popularization and promotion of electric vehicles.

[0003] The Chinese patent with the publication number CN114954080B discloses a new energy vehicle intelligent charging pile, including a base, an electrical box, and two cables. By the cooperation of a distance sensor and a pulling mechanism to quickly open an anti-collision mechanism, it realizes the protection of the new energy vehicle charging pile, and at the same time prevents the cables from being affected by strong tensile force and affecting the service life of the cables.

[0004] The Chinese patent with the publication number CN117162836B discloses a new energy vehicle intelligent charging pile, including a charging pile charging box. In the present invention, by starting the motor in the charging pile charging box, the reel drives the charging cable to start recycling. Since the charging cable passes through the upper end cover and the lower end cover during recycling, the upper end cover and the lower end cover can play a role in blocking large-particle impurities from entering the charging pile charging box, thus protecting the charging cable and the charging pile charging box well.

[0005] The above-mentioned and similar prior arts can protect the charging cable to a certain extent. However, the protection method of the prior art provides protection by reducing the friction of the charging cable. Generally, for the convenience of using the charging cable, the charging cable is usually suspended on one side of the charging pile, making the charging cable always exposed to the outside, and is easily attached by dirt such as rainwater and dust in the outside world. Even if there is a protective layer on the surface of the charging cable, it is still difficult to resist long-term dirt corrosion. Moreover, after the charging cable is attached by dirt, it will also affect the use experience of subsequent users. In addition, the charging cable is prone to certain damage during the process of being dragged and used manually, such as problems like gaps or loose connections at the connection between the charging cable and the charging pile, which may directly damage the fixed end of the charging cable and may reduce the service life of the charging cable and the charging pile.

[0006] Therefore, the present invention provides a high-performance tensile charging pile for new energy vehicles, which can automatically store the charging cable inside the charging pile in an orderly manner after the charging cable is used, and can remind the user to prevent excessive manual dragging during the use of the charging cable.

[0017] Advantages of the present invention:

[0018] (1) For the high-performance tensile charging pile for new energy vehicles of the present invention, the linkage of the storage mechanism and the reset mechanism is adopted. When the charging cable is pulled out for use, by using the pulling force received by the charging cable, the stepped ring and the synchronous ring rotate to release the charging cable from the storage groove. The elastic plate expands outwards, and the elastic potential energy increases. When the charging cable is pulled out for a certain length, the outer corrugated tube squeezes the spring to gradually increase the pulling force until the spring cannot be compressed, so that the charging cable cannot be pulled out. The elastic contraction space of the spring protects the charging cable during the dragging process. When the charging cable is no longer in use, the elastic plate releases the elastic potential energy and automatically stores the charging cable into the inner side of the storage cavity. Compared with the ordinary connection method in the prior art, this setting method of the charging cable and the charging pile not only effectively reminds the user to avoid excessive dragging during the use of the charging cable, but also improves the overall service life of the charging pile.

[0019] (2) For the high-performance tensile charging pile for new energy vehicles of the present invention, the linkage of the dust-proof mechanism and the reset mechanism is adopted. By using the misalignment of the ventilation holes between the dust-proof plate and the charging box, when the charging cable is pulled out for use, the rotating shaft rotates to lift the dust-proof plate, so that the ventilation holes of the dust-proof plate and the charging box are aligned to realize heat dissipation. When the charging cable is stored into the inner side of the storage cavity, the rotating shaft rotates to drive the support rod to rotate to the horizontal position, so that the dust-proof plate descends, and the misalignment of the ventilation holes between the dust-proof plate and the charging box realizes the sealing of the ventilation holes, improving the dust-proof effect of the charging pile.

[0020] (3) For the high-performance tensile charging pile for new energy vehicles of the present invention, no additional power source is added. Only when the charging cable is dragged by an external force, the dragging force serves as the only power source for the operation of the storage mechanism and the dust-proof mechanism, without the need for an additional power source, reducing the energy consumption during normal use.

[0037] In this embodiment, a storage mechanism 2 is arranged inside the charging box 12. The storage mechanism 2 includes a fixed tube 21, which winds and stores the charging wire 18 through a storage groove 22 opened on its outer side; the fixed tube 21 is fixedly installed inside the charging box 12 and is located on the side away from the rotating ring 13. The storage groove 22 is spiral and is opened on the outer side of the fixed tube 21. A sliding groove 23 is opened on the surface of the fixed tube 21. The sliding groove 23 is spiral and intersects with the storage groove 22. A stepped ring 24 is rotatably installed inside the fixed tube 21 through a bearing. A tooth groove is opened inside the stepped ring 24. Fixing plates 25 are respectively fixedly installed on both sides of the stepped ring 24. A guide rod 26 is fixedly installed on the side of the fixing plate 25 away from the rotating ring 13. A synchronous tube 27 is movably sleeved on the outer side of the fixed tube 21. A sliding strip 28 is fixedly installed inside the synchronous tube 27. The sliding strip 28 is spiral and is located inside the sliding groove 23. Limit sleeves 29 are respectively fixedly installed on both sides of the synchronous tube 27, and the limit sleeves 29 are located on the outer side of the guide rod 26.

[0038] Specifically, the inner side of the storage cavity 17 can provide a stable support for the fixed tube 21. The fixed tube 21 can provide a space for opening the storage groove 22 and the sliding groove 23. The storage groove 22 can provide a path for winding the charging cord and play a limiting role for the charging wire 18. The sliding groove 23 can provide a moving space for the sliding strip 28 and provide a moving path and a guiding role for the movement of the sliding strip 28. The synchronous tube 27 can provide a stable support for the sliding strip 28. When the synchronous tube 27 rotates, the synchronous tube 27 can move horizontally by the cooperation of the sliding strip 28 and the sliding groove 23.

The synchronous tube 27 can provide a stable support for the limiting sleeve 29. Through the cooperation of the guide rod 26 and the limiting sleeve 29, the synchronous tube 27 and the stepped ring 24 can rotate synchronously. The stepped ring 24 can provide a space for opening the tooth groove, enabling the tooth groove to engage with the gear 43. When the stepped ring 24 rotates, it can drive the rotating shaft 42 to rotate by the meshing action of the tooth groove and the gear 43.

[0039] In this embodiment, the friction reduction assembly 3, through the cooperation of the fixing ring 33 and the circular ring 35 arranged on the top of the fixed tube 21, can reduce the friction of the charging wire 18 inside the fixing ring 33 when the charging wire 18 is pulled out or stored. There are two sets of the friction reduction assembly 3. The two sets of the friction reduction assembly 3 are respectively located on the top of the stepped ring 24 and the synchronous tube 27, and the two sets of the friction reduction assembly 3 are mirror-image distributed. The friction reduction assembly 3 includes two sets of reinforcing plates 31. Each set of the reinforcing plates 31 has two. The two sets of the reinforcing plates 31 are respectively fixedly installed on the top of the stepped ring 24 and the synchronous tube 27. A notch plate 32 is fixedly installed between each set of the reinforcing plates 31. A plurality of notches are opened on one side of the two notch plates 32 away from each other. The fixing ring 33 is fixedly installed on the side of the notch plate 32 with notches. A plurality of annular grooves 34 are opened on the surface of the fixing ring 33, and the positions of the annular grooves 34 correspond to those of the notches one by one. The circular ring 35 is movably sleeved inside the annular groove 34.

[0040] Specifically, the stepped ring 24 and the synchronous tube 27 can provide a stable support for the reinforcing plate 31. The reinforcing plate 31 can provide a stable support for the notch plate 32, preventing the notch plate 32 from deforming under the extrusion of the charging wire 18. The notch plate 32 can provide a stable support for the fixing ring 33. The fixing ring 33 can provide a space for opening the annular groove 34. The annular groove 34 can provide a limiting effect and a rotating space for the circular ring 35. Since the fixing ring 33 is only extruded by the charging wire 18 at the position of the annular groove 34, when the charging cord is pulled out or stored and the circular ring 35 is frictionally extruded, the circular ring 35 rotates inside the annular groove 34, thereby reducing the friction between the fixing ring 33 and the charging wire 18.

[0041] In this embodiment, the reset component 4 is assembled to store elastic potential energy when pulling out the charging cable 18 through the elastic plate 44 disposed inside the fixed tube 21, and after the charging cable 18 is used up, drive the charging cable 18 to wind around the inner side of the storage groove 22 by releasing the elastic potential energy of the elastic plate 44; the reset component 4 includes a support plate 41, and the support plate 41 is fixedly installed inside the fixed tube 21. A rotating shaft 42 is installed through the inside of the support plate 41 by means of a bearing, and the rotating shaft 42 passes through the side of the charging box 12 away from the rotating ring 13 by means of a bearing. A gear 43 is fixedly installed at one end of the rotating shaft 42 close to the rotating ring 13, and the gear 43 meshes with the tooth groove of the stepped ring 24. One end of the elastic plate 44 is fixedly installed on the outer side of the rotating shaft 42, and the other end of the elastic plate 44 is fixedly installed inside the fixed tube 21.

[0042] Specifically, the fixed tube 21 can provide stable support for the support plate 41, the support plate 41 can provide rotational support for the rotating shaft 42, the rotating shaft 42 can provide stable support for the gear 43, the fixed tube 21 and the rotating shaft 42 can respectively provide stable support for the elastic plate 44, and at the same time, the inside of the fixed tube 21 can provide a moving space for the elastic plate 44. When the gear 43 drives the rotating shaft 42 to rotate, the rotating shaft 42 drives one end of the elastic plate 44 to rotate, causing the elastic plate 44 to expand outwards or contract inwards, realizing the storage and release of elastic potential energy.

[0043] In this embodiment, the anti-pulling component 5 gradually increases the force required to pull out the charging cable 18 by means of a spring 54 disposed on the inner wall of one side of the charging box 12. The anti-pulling component 5 includes two limiting strips 51, and the two limiting strips 51 are respectively fixedly installed at the top and bottom of the rotating shaft 42. An outer threaded tube 52 is movably sleeved on the outer sides of the rotating shaft 42 and the limiting strips 51. An inner threaded tube 53 is fixedly installed inside the fixed tube 21, and the inner threaded tube 53 is threadedly connected to the outer threaded tube 52. The spring 54 is fixedly installed on the inner wall of one side of the charging box 12, and the other end of the spring 54 is fixedly installed with a push plate 55. The push plate 55 is annular, and both the push plate 55 and the spring 54 are located outside the rotating shaft 42.

[0044] Specifically, the rotating shaft 42 can provide stable support for the limiting strip 51, the limiting strip 51 can provide rotational support for the outer threaded tube 52, the fixed tube 21 can provide stable support for the inner threaded tube 53, the inner threaded tube 53 can provide a threading effect for the outer threaded tube 52, the charging box 12 can provide stable support for the spring 54, the spring 54 provides stable support for the push plate 55, and the rotating shaft 42 can provide a guiding effect for the spring 54 and the push plate 55. When the charging cable 18 is pulled out, the rotating shaft 42 drives the outer threaded tube 52 to rotate through the limiting strip 51, causing the outer threaded tube 52 to move in the direction of the push plate 55 by utilizing the threading effect with the inner threaded tube 53. When there is still a small section of the charging cable 18 not pulled out, the outer threaded tube 52 contacts the push plate 55, driving the spring 54 to compress through the push plate 55. When the charging cable 18 is about to be completely pulled out, the spring 54 is compressed to the limit, using the reaction force to block the movement of the outer threaded tube 52 and also block the rotation of the rotating shaft 42, thereby preventing the charging cable 18 from being completely pulled out. The elastic contraction space of the spring 54 causes a significant change in the pulling force of the charging cable 18, which can remind the user that the charging cable 18 is about to be completely pulled out, and can also provide a buffering effect when the charging cable 18 is suddenly dragged, providing a protective effect for the fixed end of the charging cable 18.

[0045] In this embodiment, a dust-proof mechanism 6 is provided on the side of the charging box 12 away from the rotating ring 13. The dust-proof mechanism 6 is assembled to block the ventilation holes 15 through a dust-proof plate 66 provided on one side of the charging box 12. The dust-proof plate 66 itself is provided with the same ventilation holes 15, and the ventilation holes 15 of the dust-proof plate 66 are vertically offset from the ventilation holes 15 of the charging box 12. After the charging cable 18 is pulled out, the dust-proof plate 66 is lifted by the support rod 65, so that the ventilation holes 15 of the dust-proof plate 66 are aligned with the ventilation holes 15 of the charging box 12 for ventilation and heat dissipation. The dust-proof mechanism 6 includes a round cover 61, the round cover 61 is fixedly installed on the side of the charging box 12 away from the rotating ring 13, a limiting hole 62 is penetrated and opened inside the round cover 61, a friction ring 63 is rotatably installed on the outer side of the rotating shaft 42, the friction ring 63 is located inside the round cover 61, a rotating plate 64 is fixedly installed in the horizontal direction on one side of the friction ring 63, the support rod 65 is fixed to the side of the rotating plate 64 away from the charging box 12, and the support rod 65 penetrates through the inside of the limiting hole 62. The dust-proof plate 66 is movably placed on the outer side of the support rod 65. An activity hole 67 is penetrated and opened inside the dust-proof plate 66, and the activity hole 67 is located on the outer side of the support rod 65. Two through holes 68 are penetrated and opened inside the dust-proof plate 66, and two stop rods 69 are fixedly installed on one side of the charging box 12. The two stop rods 69 respectively penetrate through the inside of the two through holes 68, and part of the stop rod 69 is located on one side of the dust-proof plate 66.

[0046] Specifically, the charging box 12 can provide stable support for the round cover 61. The round cover 61 can provide a space for the through - opening of the limiting hole 62. The limiting hole 62 can provide a limiting effect for the movement of the support rod 65. The dust - proof plate 66 can provide a through - space for the through - hole 68. The through - hole 68 can provide a through - space for the blocking rod 69. The blocking rod 69 can provide a limiting effect for the dust - proof plate 66. Through the contact between the blocking rod 69 and the dust - proof plate 66, the dust - proof plate 66 is limited and attached to one side of the charging box 12 to prevent the dust - proof plate 66 from falling. The rotating shaft 42 can provide support for the friction ring 63. There is a large frictional force between the friction ring 63 and the rotating shaft 42. When the friction ring 63 drives the dust - proof plate 66 to move upward through the support rod 65, the gravity of the dust - proof plate 66 is less than the frictional force between the friction ring 63 and the rotating shaft 42, and the friction ring 63 and the rotating shaft 42 move together. When the support rod 65 contacts the inner wall of one end of the limiting hole 62, the reaction force generated by the limiting hole 62 and the support rod 65 is greater than the frictional force between the friction ring 63 and the rotating shaft 42, causing the friction ring 63 and the rotating shaft 42 to rotate relative to each other, that is, the rotating shaft 42 rotates and the friction ring 63 does not rotate.

[0047] Working principle: When the user needs to charge the car, hold and remove the gun head 19 and drag the charging cable 18 in a direction away from the charging box 12, so that the charging cable 18 is gradually pulled out from the inside of the storage cavity 17. At this time, the coiled charging cable 18 will gradually move out from the inside of the storage groove 22. At the same time, the charging cable 18 will drive the step ring 24 and the synchronous tube 27 to rotate forward through the friction - reducing assembly 3. During the rotation of the synchronous tube 27, it will move away from the step ring 24 under the guiding action of the slide bar 28 and the chute 23, so that the charging cable 18 is unwound from the inside of the storage groove 22 in a constant unwinding state. When the charging cable 18 passes through the inside of the fixed ring 33, the position where the charging cable 18 applies force to the fixed ring 33 is the position of the ring 35, so that the ring 35 rotates along the ring groove 34 by using the friction with the charging cable 18 to reduce the frictional force of the charging cable 18 during the dragging process;

[0048] During the rotation of the stepped ring 24, the stepped ring 24 drives the gear 43 to rotate by the meshing action of the tooth groove and the gear 43. The gear 43 drives the rotating shaft 42 to rotate, causing the rotating shaft 42 to drive one end of the elastic plate 44 to rotate. The elastic plate 44 is stressed and expands away from the rotating shaft 42, increasing the elastic potential energy of the elastic plate 44. At the same time, the rotating shaft 42 drives the outer threaded tube 52 to rotate through the limiting strip 51, causing the outer threaded tube 52 to move towards the push plate 55 by the threaded action with the inner threaded tube 53. When the charging cable 18 is pulled out a certain length, the outer threaded tube 52 moves to the position where it contacts the push plate 55. At this time, when the charging cable 18 is continuously pulled out, the outer threaded tube 52 squeezes the spring 54 through the push plate 55. The spring 54 uses the push plate 55 to push the outer threaded tube 52 in the opposite direction, hindering the movement of the outer threaded tube 52, thereby hindering the rotation of the rotating shaft 42 and the process of pulling out the charging cable 18. The greater the resistance during continuous dragging of the charging cable 18. When the spring 54 cannot be compressed, the charging cable 18 cannot be pulled out further. The resistance that the user needs to overcome in this process increases from small to large, which can not only remind the user that the length of the charging cable 18 is almost used up but also protect the fixed end of the charging cable 18;

[0049] During the rotation of the rotating shaft 42, the rotating shaft 42 drives the rotating plate 64 and the support rod 65 to rotate through the friction ring 63. The support rod 65 moves upward along the inner side of the limiting hole 62. At the same time, the support rod 65 drives the dust-proof plate 66 to move upward through the movable hole 67. When the support rod 65 contacts the inner wall of the other end of the limiting hole 62, the support rod 65 cannot move further. The support rod 65 uses the reaction force with the limiting hole 62 to restrict the relative rotation of the friction ring 63 and the rotating shaft 42, that is, when the rotating shaft 42 continues to rotate, the friction ring 63 does not rotate, causing the support rod 65 to support the dust-proof plate 66. At this time, the dust-proof plate 66 is aligned with the through hole 68 of the charging box 12 for heat dissipation;

[0050] After the user finishes charging, hold the gun head 19 and place it on one side of the charging box 12. At this time, the charging cable 18 is no longer dragged by an external force. The elastic plate 44 releases the elastic potential energy under its own elastic force, causing the elastic plate 44 to drive the rotating shaft 42 to rotate in the opposite direction. The rotating shaft 42 drives the gear 43 to rotate in the opposite direction, causing the gear 43 to drive the stepped ring 24 to rotate in the reverse direction by the meshing action with the tooth groove. The stepped ring 24 drives the synchronous ring to rotate synchronously in the reverse direction through the fixed plate 25 and the guide rod 26. The synchronous ring rotates in the reverse direction and moves towards the stepped ring 24 at the same time, causing the synchronous ring to gradually wind the charging cable 18 around the inner side of the storage groove 22 through the friction reduction assembly 3 at the top, storing the charging cable 18. At the same time, the anti-dragging assembly 5 and the dust-proof mechanism 6 are reset under the action of the rotating shaft 42.
