Description

Technical Field

[0001] This invention relates to the field of vehicle charging pile technology, and specifically to a new energy vehicle charging pile with a charging cable protection device. Background Technology

[0002] As the popularization of new energy vehicles accelerates, charging piles, as a core component of new energy vehicle infrastructure, play a crucial role in supporting efficient and convenient charging of electric vehicles. During the use of charging piles, the protection of charging cables is receiving increasing attention. Because charging cables typically require frequent plugging and unplugging during charging and are susceptible to being pulled, stepped on, or bent by external forces, these factors can easily damage the charging cables and pose safety hazards to users.

[0003] A Chinese patent (publication number: CN115257422A) discloses a new energy vehicle charging pile with a charging cable protection device. The charging pile includes: a charging body; a charging cable protection mechanism disposed on the charging body, the charging cable protection mechanism being used to protect the charging cable; the charging cable protection mechanism includes: a protection mechanism mounting part, mounted on the charging body; a retractable wire limiting component; and an adaptive protection part disposed within the wire limiting component, the adaptive protection part being used to protect different types of charging cables. This patent, like most existing technologies, uses a fixed charging cable winding mechanism on the charging pile to store and protect the charging cable, but the protection effect is limited. In actual charging, the charging cable still needs to be pulled out to the car's charging port. Since the charging cable is relatively long, it may sometimes be run over by nearby vehicles, especially in public charging areas. This can cause physical damage to the outer layer of the charging cable, potentially leading to cable breakage or insulation damage, posing an electrical safety hazard. Furthermore, being run over by a vehicle can exert significant pulling force on the charging gun, easily causing it to detach and become damaged. Meanwhile, some wall-mounted charging stations may have limited charging space due to the constraints of parking space layout, making it difficult for users to charge their devices. This can lead to wasted charging space and inconvenience for users. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems by providing a new energy vehicle charging pile with a charging cable protection device.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A new energy vehicle charging pile with a charging cable protection device includes a charging pile, a base is provided on the left side of the charging pile, a plurality of external insertion holes are provided on the top of the base, and a rotatable inner turntable is provided at the center of the base, with a plurality of internal insertion holes provided on the top of the inner turntable.

[0007] The top of the base is provided with a movable protective component, which includes multiple sets of outer protective plates and inner protective plates. The outer protective plates are inserted into outer insertion holes, and the inner protective plates are inserted into inner insertion holes. The outer and inner protective plates can be closed and opened simultaneously, and when closed, they can clamp the charging gun. The inner protective plate can rotate relative to the outer protective plate. A winding spacing is provided between the outer and inner protective plates, and a lifting charging cable clamp is provided between the winding spacing. The charging cable on the charging pile is divided into a coiled section, a spiral section, and an extended outer section from bottom to top. The extended outer section is connected to the charging gun. The connection between the extended outer section and the spiral section is fixedly connected to one of the inner protective plates. The connection between the spiral section and the coiled section is clamped in the charging cable clamp.

[0008] Furthermore, the inner side of the outer protective plate is provided with spirally distributed guide rubber pads, two-thirds of which wrap around the charging cable.

[0009] Furthermore, the protective assembly also includes a base rod disposed in the middle of multiple sets of outer protective plates and inner protective plates. The top of the base rod is provided with a pivot, and a bushing is sleeved on the outside of the pivot. Several inner connecting rods are annularly hinged to the outside of the base rod, and the other end of the inner connecting rod is hinged to the inner protective plate. Several outer connecting rods are annularly hinged to the outside of the bushing, and the other end of the outer connecting rod is hinged to the outer protective plate. The line connecting the two ends of the inner connecting rod and the outer connecting rod is a parallelogram.

[0010] Furthermore, one of the inner protective plates has a sliding opening inside, and a slider is slidably connected inside the sliding opening. The charging cable sleeve is fixedly connected to the slider. A transmission rod is hinged to the bottom of the base rod, and a sleeve rod is sleeved on the outside of the transmission rod. A return spring is provided between the sleeve rod and the transmission rod. The sleeve rod is hinged to the slider. A guide cone is provided at the bottom of the base rod, and a disc-shaped protrusion is provided on the outside of the sleeve rod. The disc-shaped protrusion contacts the guide cone.

[0011] Furthermore, a sleeve is provided at the top of the rotating shaft, and a plug is provided at the bottom of the charging gun.

[0012] Furthermore, a sliding groove is provided in the hinge interface of the bottom rod and the bushing, and a locking block is slidably connected inside the sliding groove. A retaining spring is provided between the locking block and the inner wall of the sliding groove. A retaining groove is provided at the hinge end of the inner connecting rod and the outer connecting rod. The retaining groove is triangular in design. When the outer protective plate and the inner protective plate are fully unfolded, the locking block is inserted into the retaining groove.

[0013] Furthermore, the outer protective plate has an upper arc-shaped guide groove on its inner top, and the inner protective plate has an upper arc-shaped guide block on its top. The upper arc-shaped guide block is slidably connected in the upper arc-shaped guide groove. When the outer protective plate is inserted into the outer insertion hole, the arc center of the upper arc-shaped guide groove and the upper arc-shaped guide block coincides with the center of the inner turntable.

[0014] Furthermore, the charging cable exit point on the charging pile is located on the back of the base.

[0015] Furthermore, the top ends of the external and internal insertion holes are extended outwards.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention adopts a split-type protective component. When the charging cable is wound up, it is fixedly installed on the base to automatically wind the charging cable. When charging, the protective component is used as a movable charging cable support. At a long distance, the protective component is placed flat, providing a long protection distance. At a close distance, the protective component is placed vertically, providing a conspicuous protection and preventing the charging cable from being excessively bent. Both can effectively prevent vehicles from running over the cable, resulting in good protection.

[0018] 2. The protective component of this invention adopts a retractable and collapsible design. When charging in a confined space, the protective component can be collapsible into a thin rod that can be held and clamp the charging gun. The charging gun can be inserted into the charging port from the outside and plugged in, making charging convenient and applicable to a wide range of applications. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1, as Figures 1-6 As shown, a new energy vehicle charging pile with a charging cable protection device includes a charging pile 1. A base 3 is provided on the left side of the charging pile 1. Several external insertion holes 31 are provided on the top of the base 3. An inner turntable 32 that can rotate is provided in the center of the base 3. Several inner insertion holes 33 are provided on the top of the inner turntable 32.

[0029] The top of the base 3 is provided with a movable protective component 4. The protective component 4 includes multiple sets of outer protective plates 41 and inner protective plates 42, preferably 3-4 sets. The outer protective plates 41 are inserted into the outer insertion hole 31, and the inner protective plates 42 are inserted into the inner insertion hole 33. The outer protective plates 41 and the inner protective plates 42 can be closed and opened at the same time. When closed, they can clamp the charging gun 2. The inner protective plate 42 can rotate relative to the outer protective plate 41. There is a winding gap between the outer protective plates 41 and the inner protective plates 42. There is a lifting charging cable clamp 431 between the winding gap. The charging cable on the charging pile 1 is divided into a coiled section, a spiral section and an extended outer section from bottom to top. The extended outer section is connected to the charging gun 2. The connection between the extended outer section and the spiral section is fixedly connected to one of the inner protective plates 42. The connection between the spiral section and the coiled section is clamped in the charging cable clamp 431.

[0030] The outer protective plate 41 has an upper arc-shaped guide groove 411 on its inner top, and the inner protective plate 42 has an upper arc-shaped guide block 421 on its top. The upper arc-shaped guide block 421 is slidably connected in the upper arc-shaped guide groove 411. When the outer protective plate 41 is inserted into the outer insertion hole 31, the arc center of the upper arc-shaped guide groove 411 and the upper arc-shaped guide block 421 coincides with the center of the inner turntable 32, so that the inner protective plate 42 can rotate stably relative to the outer protective plate 41.

[0031] During normal charging, remove the protective component 4 directly from the base 3. The coiled section of the charging cable, which is wrapped in the cable spacing, should be detached directly from below, at the opening below the cable spacing. It should be noted that when moving, the distance between the bottom of the protective component 4 and the bottom surface should be slightly greater than the diameter of the charging cable, allowing the charging cable to unwind coil by coil, giving the protective component 4 room to move. The protective component 4 and the charging gun 2 move together. With the help of the extended outer section, the charging gun 2 can detach from the protective component 4 and be inserted into the charging port. After the charging gun 2 is inserted, judge according to the charging distance. When the charging distance is far, lay the protective component 4 flat. The coiled section should be taut and aligned with the protective component 4, but not as wide as the protective component 4, to form a sufficiently long protection. At the same time, the protective component 4 is close to the charging position. Generally, the charging port of a vehicle is located at the rear wheel position, so the protective component has enough length to block the rear wheel of the adjacent vehicle, effectively preventing the adjacent vehicle from running over the charging cable. When the charging distance is short, the coiled section is not fully pulled out. At this time, most of the coiled section is still in the protective component 4. The protective component 4 is placed vertically to provide comprehensive protection for the charging cable. The protection is conspicuous and prevents the charging cable from being bent excessively. The vertical placement not only prevents it from being run over by vehicles, but also prevents pedestrians from stepping on it. The protection effect is better and it is more suitable for charging conventional vehicles.

[0032] When the car charging port is located in a confined space where it is difficult for people to enter, the coiled section is fully pulled out, and the charging cable is pulled further. The spiral section of the charging cable is lengthened, the number of spiral turns is reduced, and the spiral radius is reduced, ensuring that the charging cable is not excessively bent. At this time, the outer protective plate 41 and the inner protective plate 42 are brought together to form a thin rod that can be held, and the charging gun 2 is clamped in place. The thin rod is used to send the charging gun 2 from outside the vehicle to the charging port position and plug it in for charging. Charging in small spaces is convenient.

[0033] After charging is complete, the outer protective plate 41 and the inner protective plate 42 are in the unfolded state, the spiral section of the charging cable is restored, the outer protective plate 41 is inserted into the outer insertion hole 31, and the inner protective plate 42 is inserted into the inner insertion hole 33. Then, the inner turntable 32 is driven to rotate by the motor. The motor is a motor built into the base 3. The inner turntable 32 drives the inner protective plate 42 to rotate relative to the outer protective plate 41. The inner protective plate 42 automatically winds up the coiled section of the charging cable in the winding spacing.

[0034] Example 2, based on the above examples, such as Figure 7 As shown, a spirally distributed guide rubber pad 412 is provided on the inner side of the outer protective plate 41, and two-thirds of the guide rubber pad 412 wraps around the charging cable.

[0035] With the guide rubber pad 412 in place, during winding, the coiled section of the charging cable spirals into the winding gap under the guidance of the guide rubber pad 412, making winding more stable. When releasing the coiled section of the charging cable, because the guide rubber pad 412 wraps around two-thirds of the charging cable, it will compress the charging cable with a certain restraining force. Therefore, when pulling the charging cable downward, the charging cable will unwind from below the winding gap one coil at a time, which can better control the cable length. Although the cable release force is increased compared to Embodiment 1, it only uses the elasticity of rubber as a restraint, and the restraining force is small, which can increase the stability of winding and the control of the cable length.

[0036] In embodiment three, based on the above embodiments, the protective component 4 further includes a bottom rod 44 disposed between multiple sets of outer protective plates 41 and inner protective plates 42. The top of the bottom rod 44 is provided with a rotating shaft 441, and a bushing 45 is sleeved on the outside of the rotating shaft 441. Several inner connecting rods 46 are annularly hinged on the outside of the bottom rod 44. The other end of the inner connecting rod 46 is hinged to the inner protective plate 42. Several outer connecting rods 47 are annularly hinged on the outside of the bushing 45. The other end of the outer connecting rod 47 is hinged to the outer protective plate 41, and the line connecting the two ends of the inner connecting rod 46 and the outer connecting rod 47 is a parallelogram.

[0037] One of the inner protective plates 42 has a sliding opening 422 inside, and a slider 43 is slidably connected inside the sliding opening 422. The charging cable sleeve 431 is fixedly connected to the slider 43. The bottom of the bottom rod 44 is hinged to a transmission rod 48. A sleeve rod 49 is sleeved on the outside of the transmission rod 48. A return spring is provided between the sleeve rod 49 and the transmission rod 48. The sleeve rod 49 is hinged to the slider 43. The bottom of the bottom rod 44 is provided with a guide cone 442. The outside of the sleeve rod 49 is provided with a disc-shaped protrusion 491. The disc-shaped protrusion 491 abuts against the guide cone 442.

[0038] A sleeve 443 is provided at the top of the rotating shaft 441, and a plug 21 is provided at the bottom of the charging gun 2.

[0039] When moving, the charging gun 2 can be first inserted into the sleeve 443 through the plug 21, so that the charging gun 2 can move together with the protective component 4, making the movement more convenient. When winding the charging cable, the charging gun 2 is also inserted into the sleeve 443 through the plug 21. At this time, the inner protective plate 42 drives the bottom rod 44 to rotate synchronously through the inner connecting rod 46. The bottom rod 44 rotates synchronously through the rotating shaft 441 and the sleeve 443. The sleeve 443 drives the charging gun 2 to rotate synchronously. The charging gun 2 and the charging cable rotate together, and there will be no tangling. The charging cable can be wound stably by rotating the inner protective plate 42.

[0040] When the car charging port is located in a confined space where it is difficult for personnel to enter, the charging gun 2 is inserted into the sleeve 443 via the plug 21. Then, the charging gun 2 is pressed down, causing the charging gun 2 to drive the bottom rod 44 to descend. The bottom rod 44 drives the bushing 45 to descend. The bottom rod 44 and the bushing 45 descend simultaneously relative to the outer guard plate 41 and the inner guard plate 42. Under the action of the outer connecting rod 47 and the inner connecting rod 46, the outer guard plate 41 and the inner guard plate 42 move inward until they clamp the charging gun 2. At the same time, the bottom rod 44 drives the transmission rod 48 to descend. The transmission rod 48 drives the slider 43 to slide down along the sliding opening 422. And because the inner guard plate 42 moves inward, the transmission rod 48... It will swing inward, further pushing the slider 43 down along the sliding opening 422. At the same time, when the transmission rod 48 swings inward, the disc-shaped protrusion 491 and the guide cone 442 squeeze each other. Under the guidance of the guide cone 442, the disc-shaped protrusion 491 drives the sleeve rod 49 to slide downward relative to the transmission rod 48. The sleeve rod 49 further pushes the slider 43 down along the sliding opening 422. Therefore, with a small descent distance of the bottom rod 44, the slider 43 can slide a long distance. The slider 43 can drive the charging cable to stretch a sufficient distance through the charging cable clamp, so that the charging cable will not bend excessively. The overall control is simple, no need to apply a pulling force to the charging cable, and the deformation effect is better.

[0041] In embodiment four, based on the above embodiments, a sliding groove is provided in the hinge interface of the bottom rod 44 and the bushing 45. A locking block 451 is slidably connected inside the sliding groove. A retaining spring 452 is provided between the locking block 451 and the inner wall of the sliding groove. A locking groove is provided at the hinge end of the inner connecting rod 46 and the outer connecting rod 47. The locking groove is triangular in design. When the outer protective plate 41 and the inner protective plate 42 are fully unfolded, the locking block 451 is inserted into the locking groove.

[0042] By setting the card block 451 and the card slot, the outer protective plate 41 and the inner protective plate 42 are normally in the unfolded state and can be stably inserted back into the base 3. When the outer protective plate 41 and the inner protective plate 42 need to be closed together to form a thin rod, since the card slot is triangularly designed, it is only necessary to increase the downward pressure of the charging gun 2 to make the card block 451 disengage from the card slot.

[0043] Example 5, based on the above examples, further includes an additional feature where the charging cable lead-out position on the charging pile 1 is located on the back of the base 3. This design ensures that when the cable is retracted, the coiled section is always at the retraction position, preventing it from easily tangling on the outer protective plate 41.

[0044] The top ends of the outer insertion hole 31 and the inner insertion hole 33 are extended outwards, which facilitates the insertion of the outer protective plate 41 and the inner protective plate 42.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
