Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging piles, and in particular to a high-protection electric vehicle charging pile. Background Art

[0002] With the popularity of new energy vehicles, the demand for electric vehicle charging piles is increasing, and the potential safety hazards of vehicle charging piles have to be considered, especially for charging piles in open-air parking lots. Even if the top of the charging pile body is equipped with a sun-proof and rain-proof roof, most parking spaces are open-air. If the charging cables used in the public open air are not retracted in time, it is easy for the charging cables to be exposed to the sun and rain for a long time, and they are also easy to be accidentally crushed when later vehicles park. In this regard, in the prior art, for example, Chinese patent document CN114407705A discloses an electric vehicle charging pile with a protective function, including a mounting frame, a charging pile body, a charging plug, a winding assembly, a gun line and a charging gun, the winding assembly is used to wind the gun line to avoid the gun line being messy, and Chinese patent document CN112277690A discloses a multifunctional charging pile for new energy vehicles, which uses a winding roller to wind the cable line, and the winding shaft and winding roller used for winding are connected by a torsion spring, that is, when the charging cable is manually pulled out for charging, the elasticity of the torsion spring is overcome. The function is that when the charging is completed, the charging gun is inserted back into the charging pile, and the elastic potential energy of the torsion spring is released to automatically retract the charging cable. However, it will cause laborious pulling of the wire. At the same time, the elastic potential energy of the torsion spring is released instantly when the wire is retracted, and the retracting speed is fast. There is a problem of lack of buffering. If the existing conventional devices such as motor drive devices are used to drive the winding shaft and the winding roller to rotate and retract the wire, on the one hand, it is necessary to make major improvements to the original charging pile structure, resulting in waste of cost and energy consumption. On the other hand, it is difficult to control the automatic wire release and rewinding nodes, especially the control of the rewinding. If the wire rewinding is triggered when the charging is completed, the user has not yet pulled out the charging gun from the car charging port in time or forgets to pull out the charging gun in time, and the triggering of the wire rewinding may cause damage to the charging gun. If the wire rewinding is triggered when the charging gun is hung back to the charging pile, the user forgets to hang back the charging gun or directly drops the charging gun on the ground, and the wire rewinding cannot be triggered. If the wire rewinding is triggered when the gun is pulled out, the wire rewinding may trip or bring to the user who is hanging the gun or not leaving in time, which is not conducive to the efficient, convenient and safe use of the car charging pile.

A cable bin 8 is provided at the side end of the charging pile body 1. A second air bag 9 is provided in the cable bin 8. The second air bag 9 is connected to the first air bag 6. In the initial state, the blocker body 4 pops up upward and pushes against the inclined end face of the pressure block 7, driving the pressure block 7 to move laterally and compress the first air bag 6, so that the second air bag 9 is inflated. The charging cable 202 is wound around the outside of the expanded second air bag 9 and is gradually stored in the cable bin 8. When the car is parked in the parking space, the wheel presses down the blocker body 4, and the pressure block 7 penetrates into the hollow groove 41 along the side notch 42 and is elastically expanded by the first air bag 6, so that the second air bag 9 is in a relaxed state.

[0037] The present invention is based on the existing automobile charging pile structure, comprising a charging pile body 1 arranged at one end of a parking space, and a charging gun 2 is connected to the charging pile body 1. Fig.11 , Fig.12 As shown, the charging gun 2 is generally composed of a charging plug 201, a handle and a charging cable 202. A movable car blocker is provided at one end of the parking space close to the charging pile body 1. The movable car blocker includes an underground fixing seat 3 and a car blocker body 4 elastically connected to one end of the fixing seat 3. A transverse sliding groove 5 is provided at one end of the fixing seat 3 adjacent to the car blocker body 4. A first air storage bag 6 is elastically connected in the transverse sliding groove 5. A pressure block 7 is connected to one end of the first air storage bag 6 close to the car blocker body 4. The pressure block 7 is slidably connected to the transverse sliding groove 5. One side of the pressure block 7 is arranged with an inclined end surface. Specifically, the pressure block 7 is as shown in Figure 2 As shown in the shape design, a hollow groove 41 is provided at the lower end of the car block body 4, and a side notch 42 is opened on the side of the hollow groove 41 facing the horizontal sliding groove 5. At the same time, a cable bin 8 is provided at the side end of the charging pile body 1, and a second air storage bag 9 is provided in the cable bin 8. The second air storage bag 9 is connected to the first air storage bag 6. Specifically, the first air storage bag 6 and the second air storage bag 9 both adopt the existing conventional air bag structure with a certain elasticity, and a certain volume of air or other gas is pre-charged into the first air storage bag 6 and the second air storage bag 9. In the initial state, as shown in FIG. Figure 2As shown, the blocker body 4 pops up and pushes against the inclined end surface of the pressure block 7, driving the pressure block 7 to move laterally and compress the first air storage bag 6. Part of the gas in the first air storage bag 6 is squeezed into the second air storage bag 9, so that the second air storage bag 9 is inflated and expanded, prompting the charging cable 202 to be wound around the outside of the expanded second air storage bag 9, as shown in FIG. Figure 6 As shown, the charging cable 202 is gradually stored in the cable compartment 8. When a car is parked in the parking space, the car blocker body 4 is pressed down by the wheels, that is, the car blocker body 4 is pressed down by the weight of the car, and the car blocker body 4 moves down along the fixing seat 3, as shown in FIG. Figure 3 As shown, the first air storage bag 6 is elastically expanded, and the pressing block 7 penetrates into the hollow groove 41 along the side notch 42. At this time, the first air storage bag 6 is in an expanded and inflated state, and the second air storage bag 9 is in a relaxed state. At this time, the user gets off the vehicle and prepares to take the charging gun 2 on the charging pile body 1. Since the second air storage bag 9 is in a relaxed state at this time, the charging cable 202 stored in the cable compartment 8 loses the limit of the second air storage bag 9, as shown in FIG. Figure 7 As shown, it can be easily pulled out by the user for charging. After charging is completed, the user gets in the car and leaves the parking space, the car blocker body 4 pops up and resets, and the second air bag 9 is inflated and expanded, driving the charging cable 202 to automatically retract, wherein the top of the buried fixing seat 3 is flush with the ground or slightly lower than the ground. In the initial state, the car blocker body 4 part that pops up from the fixing seat 3 can adopt the same material, size specification and appearance design as the existing conventional pier-type fixed car blocker, that is, the car blocker body 4 part that pops out of the ground is almost the same as the conventional fixed car blocker in appearance, and also plays a similar car blocking positioning role. The present invention adopts the special design of the movable car blocker in conjunction with the above-mentioned related structural design, without making major improvements to the original charging pile structure, resulting in waste of cost and energy consumption, realizing efficient automatic retraction of the charging cable, achieving the protection of the charging pile cable used in the open air, and it is very easy to pull the cable, and has a certain buffering effect when retracting the cable. The user gets in the car and leaves the parking space, triggering the automatic retraction, which is safe to use and is conducive to further efficient, convenient and safe use of the charging cable.

[0038] In an embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 As shown, a vertical slide groove 10 with an open top is provided in the fixed seat 3, the car blocker body 4 is inserted in the vertical slide groove 10, and a horizontal slide groove 5 is provided in the fixed seat 3 at one end adjacent to the vertical slide groove 10. The end of the horizontal slide groove 5 facing the vertical slide groove 10 is open and communicates with the vertical slide groove 10. A vertical elastic member 11 is connected between the bottom end of the car blocker body 4 and the inner bottom end of the vertical slide groove 10. Specifically, multiple groups of existing conventional elastic components such as springs can be used to push the car blocker body 4 upward.

[0039] In an embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in the initial state, the portion of the blocker body 4 extending outside the fixed seat 3 is gradually closed from bottom to top, and the portion of the blocker body 4 extending into the fixed seat 3 is attached to the inner side of the fixed seat 3 and slides, that is, attached to the inner side wall of the vertical slide groove 10 and slides, and the bottom end of the portion of the blocker body 4 extending outside the fixed seat 3 is rotatably connected to the wheel blocking rod 12, as shown in FIG. Figure 5 As shown, the wheel blocking rod 12 is designed in an inverted U shape, and the bottom ends of the wheel blocking rod 12 are rotatably connected to the two ends of the long side of the car blocker body 4, and the top end of the wheel blocking rod 12 is higher than the top end of the car blocker body 4. Therefore, when a car is parked in the parking space, Figure 3 As shown, by pressing the wheel down on the car blocker body 4, the car blocker body 4 moves down along the fixing seat 3 until it is at the same height as the ground, and the wheel blocking rod 12 moves down into the fixing seat 3 together and is attached to the inner side wall of the vertical slide groove 10. Since the top of the wheel blocking rod 12 is higher than the top of the car blocker body 4 and the wheel blocking rod 12 is limited by the inner side wall of the vertical slide groove 10, it cannot rotate backward, that is, it plays the role of blocking the limited wheel, which is conducive to the wheel being efficiently pressed to the active car blocker position. Even if the wheel accidentally moves backward and passes the wheel blocking rod 12, when the car is operated to return to the forward position at this time, Figure 4 As shown, the wheel blocking rod 12 freely rotates forward and abuts against the top of the vehicle blocking device body 4, thereby not affecting the normal return of the vehicle.

[0040] In an embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 As shown, the first air storage bag 6 is designed with openings at both ends, one end opening of the first air storage bag 6 is sealed and connected to the side end of the pressure block 7, and the other end opening is sealed and connected to the side end of the transverse sliding groove 5. A transverse elastic member 13 is provided in the first air storage bag 6, and the two ends of the transverse elastic member 13 are respectively connected to the inner end of the transverse sliding groove 5 and the outer end of the pressure block 7. Specifically, multiple groups of existing conventional elastic components such as springs can be used to push the pressure block 7 to pop out laterally, and one end of the transverse sliding groove 5 away from the pressure block 7 is connected to a connecting tube 14, so that one end of the connecting tube 14 is directly connected to the first air storage bag 6, and the other end is connected to the second air storage bag 9 by underground buried wires or above-ground exposed wires.

[0041] The second air bag 9 can be in various shapes such as spherical, rectangular, etc., as long as the second air bag 9 is inflated to cause the charging cable 202 to be wound around the outside of the inflated second air bag 9, thereby driving the charging cable 202 to be retracted. Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10As shown, the second airbag 9 is strip-shaped when inflated, and a plurality of them are arranged in parallel, and the charging cable 202 is wound around the outside of each second airbag 9 in an S shape.

[0042] In an embodiment of the present invention, Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, a plurality of vertical grooves 15 are arranged in parallel in the cable bin 8, and each second air storage bag 9 is respectively arranged in the vertical groove 15. The outer side of the vertical groove 15 is slidably connected to the limiting wheel 16. When the second air storage bag 9 expands, it pushes each limiting wheel 16 to slide and disperse vertically, so that the charging cable 202 is wound between each limiting wheel 16 in an S shape.

[0043] In an embodiment of the present invention, Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, an outer notch 151 is provided on the outer side of the vertical slot 15, and both sides of the outer notch 151 are elastically connected to limit plates 152, and the upper and lower sides of the limit plates 152 are inclined so that the limit plates 152 are gradually closed toward one end of the middle of the outer notch 151. Specifically, the limit plates 152 can be designed in a trapezoidal shape, and the short side of the trapezoid faces the middle side of the outer notch 151, and the limit plates 152 on both sides pop out inward so that the short sides of the limit plates 152 on the opposite sides abut against each other, and a gap is formed between the upper and lower adjacent limit plates 152. The inner side of the limit wheel 16 is connected to the wheel shaft 17, and the wheel shaft 17 includes a first thick shaft section 171, a thin shaft section 172, and a second thick shaft section 174 connected end to end in sequence. 73, the first thick shaft section 171 is connected to the inner side of the limiting wheel 16, the thin shaft section 172 is inserted in the outer notch 151 and is located in the gap between adjacent limiting pieces 152, the second thick shaft section 173 is inserted in the vertical groove 15 and abuts against one end of the second air storage bag 9. When the second air storage bag 9 is inflated, it is blocked by the limiting piece 152 to avoid expansion to the outside of the vertical groove 15, so that the second air storage bag 9 expands along the length direction of the vertical groove 15, pushing the second thick shaft section 173 to slide vertically, and the thin shaft section 172 pushes the inclined edge of the limiting piece 152 and passes over each limiting piece 152 in turn, and is dispersed by the vertical sliding of each limiting wheel 16, so that the charging cable 202 is wound in an S shape between each limiting wheel 16.

[0044] Among them, existing Fig.11 , Fig.12 The conventional charging gun 2 structure shown in FIG. Fig.13 , Fig.14As shown, an annular airbag 18 may be provided on the outer ring of the charging plug 201, and the annular airbag 18 is connected to the first airbag 6, so that when a car is parked in the parking space, the wheel presses down the car blocker body 4, at this time, the first airbag 6 is in an expanded and inflated state, and the second airbag 9 and the annular airbag 18 are in a flat and relaxed state, so that the charging plug 201 is normally plugged into the car charging port for charging. After charging is completed, even if the user forgets to draw the gun and directly leaves the parking space, the car blocker body 4 pops up and resets, so that the second airbag 9 and the annular airbag 18 are both in an inflated and expanded state, and the annular airbag 18 expands instantly to help promote charging. The plug 201 is detached from the car charging port and the charging cable 202 is gradually driven to automatically reel in through the second air bag 9. Even if the gun hanging operation is not performed, the charging plug 201 is automatically retracted to the vicinity of the charging pile body 1 and protected by the roof of the charging pile to avoid prolonged exposure to the sun and rain, and to avoid being accidentally crushed by subsequent vehicles when parking. The automatic reeling in can only be triggered when the user gets in the car and leaves the parking space to allow the blocker body 4 to pop up upward, thereby preventing the automatic reeling from tripping or bringing the user who is hanging the gun or who does not leave in time, thereby facilitating the comprehensive high protection of the charging pile and further efficient, convenient and safe use of the charging cable.

[0045] In an embodiment of the present invention, Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.13 , Fig.14 As shown, an intermediate airbag 19 is provided in the charging pile body 1. Specifically, the intermediate airbag 19 can be provided at the bottom end of the charging pile body 1. The first air bag 6 ventilates the intermediate airbag 19 through the connecting tube 14. The intermediate airbag 19 is connected to the second air bag 9 through the air guide tube 20. Optionally, the intermediate airbag 19 is respectively connected to the second air bags 9 in each vertical groove 15 through a plurality of air guide tubes 20, one of which can be attached to the charging cable 202 and connected to the annular airbag 18. When the blocker body 4 pops up and resets, the annular airbag 18 is instantly inflated and expanded, and the charging plug 201 is pushed away from the car charging port. The second airbag 9 is gradually inflated and expanded due to the influence of the winding resistance, and gradually drives the charging cable 202 to wind up, until the blocker body 4 is completely popped out and reset, and the winding is completed.

[0046] In an embodiment of the present invention, Figure 6 , Figure 7 , Fig.13 , Fig.14As shown, the charging pile body 1 is provided with a gun hanging socket 21. Specifically, a gun hanging seat 22 is recessed on the charging pile body 1, and the gun hanging socket 21 is arranged in the recess of the gun hanging seat 22. When the gun is hung, it is beneficial to further protect the charging plug 201 from dust and rain. The outer circle of the gun hanging socket 21 is provided with an annular groove 23. When the charging plug 201 is plugged into the gun hanging socket 21, until the user's car leaves the parking space, the inflated annular airbag 18 abuts and seals in the annular groove 23, which plays a role in further stabilizing the plugging and further tightly sealing to prevent dust, rain, moisture, insects, etc., thereby facilitating the comprehensive high protection of the charging pile and further efficient, convenient and safe use of the charging cable.

[0047] The inflated annular airbag 18 can be designed to be the same height as the charging plug 201 or slightly lower than the height of the charging plug 201. The instantaneous expansion impact force is sufficient to loosen the charging plug 201 to avoid pulling and damaging the gun tip when driving away from the car.
