Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile capable of storing and protecting wiring harnesses for new energy vehicles. Background Art

[0002] In the usage scenarios of charging piles, whether it is a public parking lot or a home garage, space is a precious resource. There is currently a take-up reel driven by a clockwork spring to store the wire harness inside the charging pile. This can avoid the wire harness being placed cluttered outside the charging pile, making the space around the charging pile tidier and making effective use of limited space.

[0003] When this charging pile with a clockwork spring is actually used, when the wiring harness is pulled out and the clockwork spring is deformed, when the charging gun is inserted into the vehicle, the spring will generate pulling force on the connection between the charging gun and the vehicle through the wiring harness. The pulling force exerted by the clockwork spring will cause additional friction between the charging gun and the vehicle charging interface, making the contact part of the charging gun plug and the vehicle charging interface prone to wear, and even causing the connection between the plug and the interface to become loose, which may easily lead to charging interruption.

[0004] At the same time, when charging is finished and the charging gun is unplugged, if the user does not hold the charging gun firmly, the spring will usually reel up quickly. This is because during the charging process, the spring is always in a stretched state and stores a certain amount of elastic potential energy. Once the charging gun is unplugged, the resistance to the wiring harness is reduced, and the spring will quickly release the elastic potential energy, causing the wiring harness to be reeled up quickly. When the charging harness and the charging gun move quickly, they may touch the bodies of people around them, especially exposed parts such as hands and arms, causing pain and skin damage, and may also scratch the body surface of nearby vehicles. Especially in parking lots with dense vehicles, it can cause damage to surrounding vehicles.

[0019] A through hole is provided on the side wall of the junction box 21 near the push plate 218. The through hole of the junction box 21 is plugged and adapted to the charging gun 13. The junction box 21 is provided with an inspection door for inspecting the interior of the junction box 21. Figure 1 The inspection door is rotated open to expose the internal structure of the junction box 21. During actual use, that is, when the user needs to use the charging gun 13 to charge the vehicle, the inspection door is rotated to seal and lock the inside of the junction box 21, and only maintenance personnel can open it.

[0020] There are two charging harnesses 12 in total, one of which is fixedly connected to the winding shaft 23 and wound on the outside of the winding shaft 23, and the other is installed on the charging pile 11. A conductive slip ring is sleeved on the outside of the winding shaft 23, and the conductive slip ring is fixedly connected to the inner wall of the collection box 21. The charging harness 12 installed on the charging pile 11 passes through the inside of the collection box 21 and is connected to the conductive slip ring on the outside of the winding shaft 23 for power supply. The winding shaft 23 is provided with an electrical contact, and its electrical contact fits the inner wall of the conductive slip ring. The charging harness 12 on the winding shaft 23 is connected to the conductive slip ring through the electrical contact. The charging harness 12 on the winding shaft 23 is connected so as to achieve that during the process of rotating and pulling out the charging harness 12 on the winding shaft 23, the charging harness 12 connected to the conductive slip ring will not be affected but the power supply function can still be maintained. The above-mentioned conductive slip ring and electrical contacts are existing structures and will not be elaborated here. The charging harness 12 on the winding shaft 23 is wound in a coil shape inside the take-up drum 22 and passes through the bottom of the take-up drum 22. At the same time, the charging harness 12 passes through the junction box 21 from the side of the junction box 21 close to the through hole, and the end of the charging harness 12 away from the winding shaft 23 is fixedly connected to the charging gun 13.

[0021] Reference Figure 2 As shown, and Figure 2 For position reference, the ratchet 24 is provided with a plurality of teeth in a circular array, and the teeth are provided with vertical surfaces and inclined surfaces. The limit block 211 is fitted with the bottom of the pawl 27, and acts as a one-way limit to the rotation of the pawl 27, so that the pawl 27 can only rotate upward and cannot rotate downward.

[0022] The first triangular block 213 is located on the moving path of the second triangular block 216 , and the first triangular block 213 and the inclined surface of the second triangular block 216 are pressed and matched.

[0023] The push plate 218 is located on the moving path of the charging gun 13 when it is inserted into the junction box 21 , that is, when the charging gun 13 is inserted into the junction box 21 , the charging gun 13 pushes the push plate 218 toward the direction close to the top block 214 .

[0024] In the initial state: the charging gun 13 is plugged into the junction box 21, the charging harness 12 is completely rolled up inside the take-up reel 22, the clockwork spring 25 does not undergo elastic deformation, the telescopic end of the telescopic tube 26 is extended, so that the pawl 27 and the ratchet 24 are misaligned, the spring 1 28 is in a stretched state, the torsion spring 29 does not undergo elastic deformation, the triangle block 216 fits with the triangle block 1 213, the spring 217 is in a stretched state, and the push plate 218 fits with the charging gun 13.

[0025] When the harness assembly is used, there are two steps of use, namely, the step in which the user needs to plug in the charging gun 13 to charge the vehicle, and the step in which the user's vehicle is charged and the charging gun 13 needs to be plugged into the junction box 21. Specifically, it can be understood as the process of unwinding the charging harness 12 and the process of winding the charging harness 12, which are as follows: When the charging harness 12 needs to be released: The following are the steps that the user needs to participate in: At this time, the user holds the charging gun 13, pulls the charging gun 13 out of the junction box 21, and pulls the charging gun 13 toward the vehicle. As the charging gun 13 moves, the charging harness 12 is pulled out from the junction box 21. The user plugs the charging gun 13 into the charging port of the vehicle, and then slightly pulls the charging harness 12 toward the direction of the vehicle, and then stops pulling, so that the charging harness 12 is released an extra distance, so that the charging harness 12 between the junction box 21 and the vehicle naturally droops, so that the charging harness 12 is not in a tight state.

[0026] The following is the operation of the wiring harness assembly when the charging harness 12 is unwinding: when the charging gun 13 is pulled out of the wiring box 21, the charging gun 13 no longer contacts the push plate 218, and the elastic contraction of the spring 217 causes the slide bar 215 to slide on the top block 214 in the direction away from the ratchet 24. At this time, the triangle block 216 moves with the slide bar 215. As the triangle block 216 moves, the triangle block 216 no longer contacts the triangle block 1 213. At this time, under the elastic contraction of the spring 1 28, the telescopic end of the telescopic tube 26 moves and contracts toward the side close to the take-up reel 22, and at the same time drives the pawl 27 to move toward the ratchet 24, so that the pawl 27 is located on the rotation trajectory of the ratchet 24, and the pawl 27 is located between the teeth of the ratchet 24.

[0027] At this time, as the user uses the charging gun 13 to pull the charging harness 12 out of the junction box 21, refer to Figure 2 , Figure 3 In the orientation, the charging harness 12 drives the winding shaft 23 to rotate counterclockwise, and then the winding shaft 23 drives the ratchet 24 to rotate counterclockwise synchronously, and at the same time the clockwork spring 25 produces elastic deformation. While the ratchet 24 rotates counterclockwise, the inclined surfaces of each tooth of the ratchet 24 will successively contact the pawl 27, so that the pawl 27 rotates upward with the telescopic tube 26 as the rotation axis, and drives the torsion spring 29 to deform. When one tooth on the ratchet 24 rotates until it no longer conflicts with the pawl 27, the torsion spring 29 elastically resets, causing the pawl 27 to rotate in the opposite direction, so that the pawl 27 continues to conflict with the inclined surface of another tooth on the ratchet 24, and then during the rotation of the ratchet 24, the pawl 27 cannot hinder the counterclockwise rotation of the ratchet 24, that is, the unwinding process of the charging harness 12.

[0028] When the user plugs the charging gun 13 into the charging port of the vehicle, that is, the user no longer pulls out the charging harness 12 from the inside of the junction box 21, that is, the charging harness 12 no longer applies tension to the spring 25 through the winding shaft 23. At this time, if the spring 25 is elastically reset, the spring 25 will drive the winding shaft 23 to rotate in the opposite direction, and the charging harness 12 will be wound up, so that the charging harness 12 pulls the charging gun 13 in the opposite direction. However, when the ratchet 24 rotates in the opposite direction, refer to Figure 2 As shown, that is, when it tends to rotate clockwise, the vertical surface of the teeth of the ratchet 24 will conflict with the pawl 27, and with the elastic reset trend of the clockwork spring 25, the ratchet 24 applies pressure to the pawl 27, driving the pawl 27 to rotate downward, but due to the limiting effect of the limit block 211, the ratchet 24 cannot rotate clockwise at this time, that is, the clockwork spring 25 cannot be elastically reset, and then the length and slack of the charging harness 12 can be fixed. In summary, after the user pulls out the charging harness 12, even if no force is applied to the charging harness 12, the length and slack of the charging harness 12 can be fixed.

[0029] After the user completes the connection and charging between the charging gun 13 and the vehicle, the user still slightly pulls the charging harness 12 toward the vehicle to extend the charging harness 12 a certain distance, so that the charging harness 12 is not in a tight state and is placed on the ground. Through the operation of the harness assembly, the charging harness 12 can be kept in a relaxed state while the charging gun 13 is connected to the user's vehicle, that is, the clockwork spring 25 cannot generate tension on the connection between the charging gun 13 and the vehicle, thereby avoiding additional friction between the charging gun 13 and the vehicle charging interface, causing wear on both of them, and at the same time, the connection between the charging gun 13 and the vehicle charging port can be made stable, ensuring a good connection between the charging gun 13 and the vehicle charging interface, and reducing charging failures caused by interface damage.

[0030] Through the operation of the wiring harness assembly, after the user pulls out the charging harness 12, there is no need to worry about the charging harness 12 automatically retracting or becoming too loose to affect the charging operation. For example, when connecting the charging gun 13 to the vehicle charging interface, the user can operate the charging gun 13 with both hands instead of holding the charging harness 12 with one hand to prevent it from retracting, which facilitates the process of plugging and unplugging the charging gun 13 for the user. Especially for users with less strength or limited mobility, this design of fixing the length and looseness of the charging harness 12 can improve the convenience of operation.

[0031] When the user finishes charging the vehicle and needs to reel in the charging harness 12: The following are the steps that the user needs to participate in: At this time, the user holds the charging gun 13, pulls the charging gun 13 out of the vehicle charging port, and plugs the charging gun 13 into the through hole on the junction box 21.

[0032] The following is the operation of the harness assembly when the charging harness 12 is reeled up: As can be seen from the above, after the user pulls out the charging gun 13 from the charging port of the vehicle, the spring spring 25 is restricted by the pawl 27 and the ratchet 24 and cannot rotate in the opposite direction, that is, the charging harness 12 cannot be automatically reeled up by the spring spring 25; When the user inserts the charging gun 13 into the through hole on the junction box 21, the charging gun 13 pushes the push plate 218 in the direction close to the top block 214, so that the triangle block 216 contacts the triangle block 1 213. Combined with the above, at this time, the telescopic end of the telescopic tube 26 pushes the pawl 27 in the direction away from the take-up reel 22, so that the pawl 27 gradually separates from the ratchet 24, and then the pawl 27 is no longer located on the rotation path of the ratchet 24. At this time, the pawl 27 cannot limit the elastic reset of the clockwork spring 25. Under the action of the elastic reset of the clockwork spring 25, the winding shaft 23 is driven to rotate in the opposite direction, and the charging harness 12 is wound into the inside of the take-up reel 22.

[0033] Through the above movement steps, it can be concluded that the charging harness 12 will only be reeled in when the user plugs the charging gun 13 into the through hole on the junction box 21. When the charging harness 12 is reeled in, the user is already standing in the safe area around the charging pile 11, and the charging gun 13 cannot move after the plugging is completed. This can avoid the risk in the prior art that the user fails to hold the charging gun 13 firmly, resulting in the risk of rapid reeling and movement of the charging harness 12 and the charging gun 13 causing damage to surrounding personnel and vehicles, thereby greatly improving the safety of the charging process.

[0034] Embodiment 2: During the actual use of the charging harness 12 and the charging gun 13, the charging harness 12 will be directly exposed to the external environment. If the external environment is humid, such as in rainy and snowy weather, the surface of the charging harness 12 will carry dust, impurities, leaves, moisture and other substances. When the charging harness 12 is rolled up and enters the take-up reel 22, it will corrode the metal parts and electrical connection points inside the junction box 21, increasing the risk of short circuit. At the same time, impurities adhere to the surface of the charging harness 12. During the winding and unwinding process, the friction between the charging harness 12 and the junction box 21, the take-up reel 22, the winding shaft 23 and other parts will increase. This additional friction will cause the outer skin of the charging harness 12 to wear more severely, making the internal wires more easily exposed. Once the wires are exposed, there is a risk of leakage.

[0035] like Figures 1 to 3 as well as Figures 8 to 12As shown, in order to solve the above-mentioned problem, a debris removal and dehumidification component is further provided on the wire collection box 21, and the debris removal and dehumidification component is used to remove impurities and moisture on the charging wire harness 12 during the winding process of the charging wire harness 12, and the debris removal and dehumidification component includes a long-handled bevel gear 31, and the long-handled bevel gear 31 is rotatably connected to the outer wall of the take-up reel 22 on one side close to the ratchet 24, and a belt 32 is connected between the long-handled bevel gear 31 and the ratchet 24 through a pulley transmission, and a bottom block 33 is fixedly connected to the bottom of the inner wall of the wire collection box 21, and a rotating shaft 34 is rotatably connected to the top of the bottom block 33, and a side bevel gear 35 is fixedly connected to the end of the rotating shaft 34 close to the long-handled bevel gear 31, and the side bevel gear 35 is meshed with the long-handled bevel gear 31, and the end of the rotating shaft 34 away from the side bevel gear 35 passes through the wire collection box 21. Four triangular rods 36 are fixedly connected, and a square tube 37 is fixedly connected to the outer wall of the junction box 21 on one side close to the triangular rod 36. Four fixed plates 38 are fixedly connected to the square tube 37 in a linear array. A circular scraper 39 is fixedly connected to one side of the four fixed plates 38 close to the rotating shaft 34. The four circular scrapers 39 are all provided with a plurality of water filtering holes 310 in a ring array. A sponge 311 is fixedly connected inside the four circular scrapers 39. Four slide plates 312 are slidably connected to the square tube 37 in a linear array. Four springs 313 are sleeved on the square tube 37. One end of the four slide plates 312 close to the rotating shaft 34 is fixedly connected to a pressure block 314. The four pressure blocks 314 are fixedly connected to a curved triangular block 315 on one side close to the rotating shaft 34.

[0036] Reference Fig.11 As shown, four triangular rods 36 are arranged in a spiral array on the rotating shaft 34 in the direction away from the junction box 21, and the four circular scrapers 39, the sponge 311 and the four pressure blocks 314 are all provided with holes for the charging harness 12 to pass through, and the sponge 311 is in a tightly fitted state with the outer surface of the charging harness 12.

[0037] One end of the four spring threes 313 away from the junction box 21 is fixedly connected to a side of the adjacent slide plate 312 close to the junction box 21, one spring three 313 close to the side of the junction box 21 is fixedly connected to the junction box 21, and one end of the remaining three spring threes 313 close to the junction box 21 are fixedly connected to the adjacent fixed plate 38.

[0038] The four curved triangular blocks 315 are respectively located on the rotation paths of the four triangular rods 36 , and the upper ends of the curved triangular blocks 315 are provided with inclined surfaces that are pressed and matched with the corresponding triangular rods 36 .

[0039] The pressing block 314 is plug-fitted with the circular scraper 39 .

[0040] When the impurity removal and moisture removal component is used, it is mainly used in the process of winding up the charging harness 12 in rainy and snowy weather, specifically as follows: When the charging harness 12 is rolled up, a section of the charging harness 12 exposed outside the junction box 21, hereinafter referred to as the dirty section, is contaminated with substances such as water droplets, dust and sand, and is referred to as water and solid impurities below. At this time, the dirty section of the charging harness 12 is quickly rolled up from the outside to the inside of the junction box 21. During the rolling process of the dirty section of the charging harness 12, it will first slide from the four circular scrapers 39 and the inside of the four sponges 311 in turn. When the dirty section of the charging harness 12 slides inside the circular scraper 39, the solid impurities carried on its surface will be The circular scraper 39 blocks the water on the surface of the dirty segment of the charging harness 12 and is absorbed by the sponge 311. The removal of solid impurities and water is performed four times in sequence, so that the solid impurities and water on the dirty segment of the charging harness 12 are blocked outside the junction box 21, thereby preventing the solid impurities and water from corroding the metal parts and electrical connection points inside the junction box 21, and preventing the short circuit of the charging pile 11 caused by the intrusion of water vapor and the erosion of foreign matter, thereby ensuring the normal use of the charging pile 11 and extending the service life of the charging gun 13.

[0041] At the same time, by blocking the solid impurities and moisture on the dirty segments of the charging harness 12 outside the junction box 21, solid impurities can be prevented from entering the interior of the junction box 21, reducing the friction between the charging harness 12 and components such as the junction box 21, the take-up reel 22, and the winding spool 23. At the same time, reducing friction can ensure the integrity of the outer skin of the charging harness 12, ensure the insulation performance of the winding spool 23, and improve the safety of charging.

[0042] At the same time, during the winding process of the charging harness 12, combined with the operation of the harness assembly described above, it can be seen that the ratchet 24 will rotate during the winding process of the charging harness 12. While the ratchet 24 rotates, the long-handled bevel gear 31 will be driven to rotate synchronously through the belt 32. While the long-handled bevel gear 31 rotates, the side bevel gear 35 will drive the rotating shaft 34 to rotate synchronously, and then the four triangular rods 36 will rotate synchronously. When the triangular rod 36 rotates to contact the curved triangular block 315, the triangular rod 36 fits with the inclined surface of the curved triangular block 315, and pushes the curved triangular block 315 to move away from the collection box 21. While the curved triangular block 315 moves, it drives the corresponding pressure block 314 to move synchronously with the slide plate 312, and stretches the corresponding spring three 313. The pressure block 314 is driven by the curved triangular block 315 to be inserted into the adjacent circular scraper 39. At this time, refer to Fig.12As shown, the pressing block 314 runs from the left side of the charging harness 12 to the state shown on the right side, that is, the pressing block 314 squeezes and deforms the sponge 311, so that the water inside the sponge 311 is squeezed out, and the squeezed water is discharged to the outside through the water filter hole 310. As the rotating shaft 34 continues to rotate, when the triangular rod 36 rotates to no longer conflict with the curved triangular block 315, the slide plate 312, the pressing block 314 and the curved triangular block 315 are driven to reset under the elastic contraction of the spring three 313. The four triangular rods 36 are spirally arranged and staggered, so that the four triangular rods 36 and their corresponding curved triangular blocks 315 are intermittently conflicting, that is, at the same time, one of the four sponges 311 will be squeezed to remove water. In the process of winding the charging harness 12, the four sponges 311 will intermittently remove water, and three sponges 311 are maintained to provide water absorption function for the dirty segments of the charging harness 12, that is, the internal moisture can be automatically removed during the sponge 311 absorbing water, but the function of removing moisture on the surface of the harness is still maintained. The purpose of this is to prevent the charging harness 12 from carrying too much moisture in a rainy environment. By intermittently squeezing and removing water, the sponge 311 can always maintain a high water absorption capacity. When one sponge 311 is squeezed to remove water, the other three sponges 311 are still absorbing water normally. In this way, the effect of removing moisture on the surface of the charging harness 12 will not be reduced due to the saturation of the sponge 311.

[0043] The sponge 311 can always maintain a high water absorption capacity, so that no matter in a high humidity environment or when the user charges frequently, the impurity removal and dehumidification component can effectively cope with the work of removing moisture from the surface of the charging harness 12, thereby enhancing the adaptability of the impurity removal and dehumidification component to different working conditions.
