Description

Technical Field

[0001] This application relates to the technical field of charging piles, and more specifically, to a multifunctional electric vehicle charging pile and its usage method. Background Art

[0002] As the market share of electric vehicles in the automotive market gradually increases, the number of electric vehicle charging piles has also gradually increased. Currently, most of the charging cables in charging piles are exposed, resulting in easy wear of the outer skin of the cable. The patent document with the publication number CN111873837B in the prior art provides a multifunctional charging pile structure for electric vehicles, which sets a roller wire winding mechanism to wind and unwind the cable, so that when not charging, the cable can be stored in the cabinet to protect the cable.

[0003] Regarding the above related technology, the inventor believes that the roller wire winding mechanism can only convey the cable into the cabinet and cannot stack the cable in an orderly manner, making the cable prone to entanglement and knotting during the next use, thereby affecting the use of the charging pile. In view of this, we propose a multifunctional electric vehicle charging pile and its usage method. Summary of the Invention

[0004] 1. Technical Problems to be Solved

[0005] The purpose of this application is to provide a multifunctional electric vehicle charging pile and its usage method, which solves the technical problems in the above background art and achieves the technical effect of arranging the cable in an orderly manner and preventing entanglement and knotting.

[0006] 2. Technical Solutions

[0007] This application provides a multifunctional electric vehicle charging pile, including:

[0008] Cabinet 1;

[0009] Moving box 2, movably arranged in the groove 101 opened on the cabinet 1;

[0010] Two symmetrically arranged wire winding wheels 4 are rotatably connected to the right inner wall of the moving box 2 for winding the cable;

[0011] Driving mechanism 5, arranged in the moving box 2, used to drive the wire winding wheel 4 to rotate, and a plurality of moving mechanisms 7 are connected to the driving mechanism 5;

[0012] Clamping assembly 8, connected to the moving mechanism 7, used to drive the cable to move.

[0013] In the above technical solution, the cable can be arranged in a serpentine tubular shape in the moving box 2 through the clamping assembly 8. While pushing the moving box 2, the driving mechanism 5 is operated. The driving mechanism 5 drives the wire twisting wheel 4 to rotate, and at the same time, the driving mechanism 5 drives multiple clamping assemblies 8 to intermittently move towards the wire twisting wheel 4. So that while the moving mechanism 7 and the clamping assembly 8 cooperate to drive the clamped cable to move, the wire twisting wheel 4 conveys the cable to the outside of the moving box 2.

[0014] In the above preferred technical solution, a plurality of warning lights 3 are fixedly installed on the top surface of the moving box 2.

[0015] In the above technical solution, the warning lights 3 are beneficial to warning the position of the moving box 2, effectively preventing personnel and vehicles from colliding with the moving box 2.

[0016] In the above preferred technical solution, a mounting plate A is fixedly connected to the left side inside the moving box 2, and a mounting plate B is fixedly connected to the right side inside the moving box 2. The driving mechanism 5 includes a lead screw 501, and the lead screw 501 is rotatably connected between the mounting plate A and the mounting plate B. A motor 502 is fixedly installed on the left outer wall of the mounting plate A, and the left end of the lead screw 501 is drivingly connected to the motor 502. Both ends of the lead screw 501 are fixedly connected with rotating shafts 503, and the outer ends of the rotating shafts 503 are both drivingly connected with screws 504. A limiting rod 505 is threadedly sleeved on the screw 504.

[0017] The limiting rod 505 is arranged in a cuboid structure, and square holes matching the limiting rod 505 are opened on both the mounting plate A and the mounting plate B. The limiting rods 505 are all slidably limited in the corresponding square holes;

[0018] The wire twisting wheel 4 and the lead screw 501 are both located at the upper end inside the moving box 2. The cable led out from the cabinet 1 enters the moving box 2 from the upper right side of the moving box 2. The cable located in the moving box 2 sequentially passes around the wire twisting wheel 4 and the clamping assembly 8, then passes through the upper side of one end of the mounting plate A and is led out of the moving box 2 and connected with a charging gun. When the cable is wound into the moving box 2, the cable located between the mounting plate A and the clamping assembly 8 is arranged in a serpentine tubular shape.

[0019] In the above technical solution, the motor 502 drives the lead screw 501 to rotate, and the lead screw 501 drives the screw 504 to rotate through the rotating shaft 503, so that the limiting rods 505 on both sides move horizontally in the same direction.

[0020] In the above preferred technical solution, the rotating shaft 503 on the right is connected to the wire stranding wheel 4 through a transmission assembly 6. The transmission assembly 6 includes a transmission shaft 601 coaxially connected to the wire stranding wheel 4. Rotating gears 602 are fixedly sleeved on the transmission shaft 601. The two rotating gears 602 are meshed and connected. One end of the transmission shaft 601 is fixedly sleeved with a bevel gear A603, and the bevel gear A603 is meshed and connected with a bevel gear B604 fixedly sleeved on the corresponding rotating shaft 503.

[0021] In the above technical solution, the rotating shaft 503 makes the transmission shaft 601 rotate through the cooperation of the bevel gear B604 and the bevel gear A603. The transmission shaft 601 and the rotating gear 602 cooperate to make the two wire stranding wheels 4 rotate in opposite directions to realize the conveyance of the clamped cable.

[0022] In the above preferred technical solution, the moving mechanism 7 includes a plurality of screw sleeves 701 threadedly engaged with the lead screw 501. Annular grooves are formed in the middle of the sides of the screw sleeves 701. The screw sleeves 701 are rotatably connected to a limit seat 702 through the annular grooves on them. The limit seat 702 is slidably connected to the moving box 2. Plug-in limit blocks arranged in a hollow structure are fixedly connected to the sides of the limit seat 702. The hollow part of the plug-in limit block is communicated with the inside of the limit seat 702. A connecting rod 703 is slidably connected in the hollow part of the plug-in limit block. One end of the connecting rod 703 is inserted and cooperated with a locking groove 704 formed on the screw sleeve 701;

[0023] A square through hole is formed in the side wall of one end of the connecting rod 703. A connecting plate is slidably limited in the square through hole. The two ends of the connecting plate are fixedly connected between the inner walls of the hollow part. A spring 705 is connected between the lower outer wall of the connecting plate and the lower inner wall of the square through hole.

[0024] By adopting the above technical solution, when the connecting rod 703 is not inserted into the locking groove 704, the lead screw 501 drives the screw sleeve 701 to rotate in place. When the connecting rod 703 is inserted into the locking groove 704, the screw sleeve 701 cannot rotate. Under the limitation of the limit seat 702, the lead screw 501 drives the screw sleeve 701 to move.

[0025] In the above preferred technical solution, the other end of the connecting rod 703 is fixedly connected with a limit sleeve 706. Protrusions 707 are fixedly connected to the upper inner walls of the limit sleeve 706. The left and right ends of the protrusions 707 are both arranged in an inclined structure. An inclined surface matched with the inclined structure is formed in the inner end of the limit rod 505. The protrusions 707 are in movable contact and cooperation with the limit rod 505.

[0026] By adopting the above technical solution, when the protrusions 707 contact the limit rod 505, the limit sleeve 706 drives the connecting rod 703 to disengage from the insertion into the locking groove 704.

[0027] In the above preferred technical solution, the clamping assembly 8 includes a fixing plate 801 fixedly connected to the limit seat 702. Two connecting shafts 802 are rotatably connected to the fixing plate 801, and a limit wheel 803 is fixedly connected to one end of each connecting shaft 802.

[0028] By adopting the above technical solution, the two limit wheels 803 cooperate to clamp the cable. When the fixing plate 801 moves along with the moving mechanism 7, the limit wheels 803 drive the cable to move synchronously.

[0029] In the above preferred technical solution, two brake plates 804 are slidably connected to the fixing plate 801. The brake plates 804 are in sliding contact with the connecting shafts 802. A limit plate 9 is fixedly connected inside the moving box 2, and a limit groove 901 is formed in the limit plate 9. The brake plates 804 are in sliding contact with the limit groove 901.

[0030] The left side of the limit groove 901 has a narrow groove part, and the right side has a wide groove part. When the clamping assembly 8 is located in the right part of the limit groove 901, the limit wheels 803 can rotate, which is convenient for the stranding wheel 4 to convey the cable into the moving box 2. When the clamping assembly 8 moves to the left, the brake plates 804 are gradually and tightly in contact with the limit groove 901, which can prevent the connecting shafts 802 from rotating, so that the limit wheels 803 cannot rotate during the movement of the clamping assembly 8, improving the stability when driving the cable to move.

[0031] By adopting the above technical solution, when the brake plates 804 are slightly in contact with the edge of the limit groove 901, the connecting shafts 802 can rotate between the brake plates 804 and the fixing plate 801. When the brake plates 804 are tightly in contact with the edge of the limit groove 901, the brake plates 804 are tightly in contact with the connecting shafts 802, and the connecting shafts 802 do not rotate.

[0032] In the above preferred technical solution, a sliding plate 10 is slidably connected to one side of the moving box 2. A clamping seat 11 is fixedly connected to the sliding plate 10, and a fastening bolt 12 is threadedly connected to the sliding plate 10. One end of the fastening bolt 12 is in abutting cooperation with the moving box 2.

[0033] By adopting the above technical solution, rotating the fastening bolt 12 can adjust the height of the sliding plate 10, so that when the charging gun is connected to the current vehicle for charging, the charging gun will not be disconnected from the charging port due to the gravity of the cable.

[0034] A method for using the above multifunctional electric vehicle charging pile includes the following steps:

[0035] When charging an electric vehicle, push the moving box 2 towards the vehicle;

[0036] The starting motor 502 drives the lead screw 501 and the rotating shaft 503 to rotate. The rotating shaft 503 drives the screw rod 504 to rotate. The screw rod 504 drives the limit rod 505 to move. When the contact between the limit rod 505 and the convex block 707 is cancelled, the spring 705 drives the connecting rod 703 to be inserted into the locking groove 704. The lead screw 501 cooperates with the screw sleeve 701 and the limit seat 702 to drive the clamping assembly 8 to move, so that the two limit wheels 803 drive the clamped cable to be transported towards the stranding wheel 4. One rotating shaft 503 drives the two stranding wheels 4 to rotate in the opposite direction through the transmission assembly 6, and the two stranding wheels 4 cooperate to convey the cable stored in the moving box 2 to the outside;

[0037] Remove the charging gun from the card seat 11 and insert it into the charging port of the vehicle for charging;

[0038] When charging is completed, remove the charging gun and make it snap onto the card seat 11, and push the moving box 2 to move into the groove 101;

[0039] The motor 502 rotates in the reverse direction, so that the stranding wheel 4 drives the cable to be conveyed into the moving box 2. At the same time, the screw sleeve 701 and the limit seat 702 cooperate to drive the clamping assembly 8 to move in the reverse direction, and the two limit wheels 803 cooperate to clamp the cable to move, so that the cable is arranged in a serpentine tubular shape in the moving box 2.

[0040] 3. Beneficial effects

[0041] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0042] In the present application, the lead screw and the rotating shaft cooperate to drive the screw rod and the stranding wheel to rotate. The stranding wheel conveys the cable into the moving box. At the same time, the screw rod drives the limit rod to slide. After the contact between the limit rod and multiple convex blocks is intermittently cancelled, multiple moving mechanisms move intermittently. The limit wheels drive the cable to be arranged in a serpentine tubular shape in the moving box, avoiding the entanglement and knotting of the cable, and effectively protecting the cable.

[0076] The present invention also aims to provide a usage method of a multifunctional electric vehicle charging pile, including the following steps:

[0077] When charging an electric vehicle, push the moving box 2 towards the vehicle.

[0078] Start the motor 502 to drive the lead screw 501 and the rotating shaft 503 to rotate. The rotating shaft 503 drives the screw rod 504 to rotate.

[0079] Take the charging gun off the clamping seat 11 and insert it into the charging port of the vehicle for charging.

[0080] When charging is completed, take the charging gun off and make it snap onto the clamping seat 11, and push the moving box 2 into the groove 101.

[0081] The motor 502 rotates in the reverse direction, so that the wire winding wheel 4 drives the cable to be conveyed into the moving box 2. At the same time, the screw sleeve 701 cooperates with the limiting seat 702 to drive the clamping assembly 8 to move in the reverse direction, and the two limiting wheels 803 cooperate to clamp the cable to move, so that the cable is arranged in a serpentine tubular shape inside the moving box 2.

[0082] The following is a list of preferred embodiments of the present invention in conjunction with the accompanying drawings to further illustrate the present invention in detail.

[0083] Referring to Figures 1-9 , the present application includes a cabinet body 1. A groove 101 is formed on the cabinet body 1. A moving box 2 is movably placed in the groove 101. The cable on the cabinet body 1 passes through the moving box 2 and is connected to a charging gun. Two stranding wheels 4 arranged side by side are rotatably connected in the moving box 2. A driving mechanism 5 is arranged in the moving box 2. The driving mechanism 5 drives the two stranding wheels 4 to rotate. A plurality of moving mechanisms 7 are connected to the driving mechanism 5. The plurality of moving mechanisms 7 can translate intermittently. And a clamping assembly 8 is connected to the moving mechanism 7 to clamp the cable. When the moving mechanism 7 drives the clamping assembly 8 to move to the side away from the stranding wheel 4, the cable can be arranged in a serpentine tubular shape in the moving box 2.

[0084] Referring to Figure 2 , a plurality of warning lights 3 are fixedly installed on the top surface of the moving box 2. The warning lights 3 can provide a warning effect to prevent personnel and vehicles from hitting the moving box 2.

[0085] Referring to Figure 3 , the driving mechanism 5 includes a lead screw 501. One end of the lead screw 501 is in transmission connection with a motor 502. Both ends of the lead screw 501 are fixedly connected with a rotating shaft 503. One end of each rotating shaft 503 is in transmission connection with a screw rod 504. A limiting rod 505 is threadedly sleeved on each screw rod 504. When the lead screw 501 drives the screw rod 504 to rotate through the rotating shaft 503, the limiting rods 505 on both sides move in the same direction and in parallel.

[0086] Referring to Figure 4 , the rotating shaft 503 on the right side is connected to the stranding wheel 4 through a transmission assembly 6. The transmission assembly 6 includes a transmission shaft 601 coaxially connected to the stranding wheel 4. Rotating gears 602 are fixedly sleeved on the transmission shaft 601. The two rotating gears 602 are meshed and connected. A bevel gear A603 is fixedly sleeved at one end of one of the transmission shafts 601. The bevel gear A603 is meshed with a bevel gear B604 fixedly sleeved on the corresponding rotating shaft 503. The rotating shaft 503 drives one transmission shaft 601 to rotate, and drives the two stranding wheels 4 to rotate in opposite directions through the cooperation of the two rotating gears 602 to realize the conveying of the cable.

[0087] Referring to Figure 5, the moving mechanism 7 includes a plurality of screw sleeves 701 that are slidably engaged with the lead screw 501. A limit seat 702 is rotatably connected to the screw sleeve 701. The limit seat 702 is slidably connected to the moving box 2. A connecting rod 703 is slidably connected within the limit seat 702. One end of the connecting rod 703 is inserted and engaged with a locking groove 704 formed on the screw sleeve 701, and the connecting rod 703 is connected to the limit seat 702 through a spring 705. When the connecting rod 703 is not inserted into the locking groove 704, the screw sleeve 701 can rotate within the limit seat 702, enabling the lead screw 501 to drive the screw sleeve 701 to rotate in place. When the connecting rod 703 is inserted into the locking groove 704, the screw sleeve 701 is connected to the limit seat 702, and the cooperation between the lead screw 501 and the screw sleeve 701 drives the limit seat 702 to translate within the moving box 2.

[0088] Refer to Figure 6 , the other end of the connecting rod 703 is fixedly connected to a limit sleeve 706. A convex block 707 is fixedly connected within the limit sleeve 706. When the limit rod 505 contacts the convex block 707, the convex block 707 and the limit sleeve 706 cooperate to drive the connecting rod 703 to rise, causing the connecting rod 703 to disengage from the locking groove 704.

[0089] Refer to Figure 5 With Figure 6 , when the two limit rods 505 move to the right, the right limit rod 505 cancels contact with the plurality of convex blocks 707 one by one. After the contact is cancelled, the spring 705 can drive the connecting rod 703 to move to be inserted into the locking groove 704. At this time, the cooperation between the lead screw 501 and the screw sleeve 701 drives the entire moving mechanism 7 to move to the left until the current moving mechanism 7 contacts the left limit rod 505, causing the convex block 707 to drive the connecting rod 703 to disengage from the locking groove 704 again. Subsequently, the next moving mechanism 7 performs the same movement as described above.

[0090] Refer to Figure 7 , the clamping assembly 8 includes a fixing plate 801 fixedly connected to the limit seat 702. Two connecting shafts 802 are rotatably connected to the fixing plate 801. One end of the connecting shaft 802 is fixedly connected to a limit wheel 803. The limit wheel 803 can rotate through the connecting shaft 802, and the two limit wheels 803 cooperate to clamp and limit the cable.

[0091] Refer to Figure 7 With Figure 8, two brake plates 804 are slidably connected to the fixed plate 801. A limiting plate 9 is fixedly connected inside the moving box 2. A limiting groove 901 is formed in the limiting plate 9. The left groove part of the limiting groove 901 is narrow and the right groove part is wide. When the clamping assembly 8 is located in the right part of the limiting groove 901, the limiting wheel 803 can rotate, facilitating the wire winding wheel 4 to convey the cable into the moving box 2. When the clamping assembly 8 moves to the left, the brake plate 804 gradually comes into close contact with the limiting groove 901, which can prevent the coupling shaft 802 from rotating, so that the limiting wheel 803 cannot rotate during the movement of the clamping assembly 8, improving the stability when driving the cable to move.

[0092] Referring to Figure 9 , a sliding plate 10 is slidably connected to one side of the moving box 2. One end of the cable passes through the sliding plate 10 and is fixed to the sliding rod 10. A clamping seat 11 is fixedly connected to the sliding plate 10. The charging gun can be clamped on the clamping seat 11, facilitating personnel to use and take. A fastening bolt 12 is threadedly connected to the sliding plate 10. Rotating the fastening bolt 12 can adjust the height of the sliding plate 10, so that when the charging gun is connected to the vehicle, the height of the cable is higher than that of the charging gun, preventing the charging gun from falling off the vehicle connection due to the influence of the gravity of the cable.

[0093] The implementation principle of a multifunctional electric vehicle charging pile and its usage method in the embodiment of the present application is as follows: When in use, the moving box 2 is pushed out from the groove 101 and pushed beside the vehicle, and the motor 502 is driven to drive the lead screw 501 to rotate. The lead screw 501 drives the screw rod 504 and the wire winding wheel 4 to rotate. The screw rod 504 drives the limiting rod 505 to move to the left. The left limiting rod 505 cancels contact with the multiple convex blocks 707 one by one. After the contact is cancelled, the spring 705 can drive the connecting rod 703 to move to be inserted into the locking groove 704. At this time, the lead screw 501 and the nut sleeve 701 cooperate to drive the entire moving mechanism 7 to move to the right. The two limiting wheels 803 drive the serpentine tube-shaped cable to move towards the wire winding wheel 4. At the same time, the rotating shaft 503 and the transmission assembly 6 cooperate to drive the two wire winding wheels 4 to rotate in opposite directions. The wire winding wheel 4 drives the cable to be conveyed outside the moving box 2. When it moves beside the vehicle, the motor 502 is stopped from rotating. The charging gun is taken off the clamping seat 11, and the charging gun is connected to the vehicle for charging. Rotating the fastening bolt 12 can adjust the height of the sliding plate 10, so that when the charging gun is connected to the vehicle, the height of the cable is higher than that of the charging gun, preventing the charging gun from falling off the vehicle connection due to the influence of the gravity of the cable.

[0094] After charging is completed, the charging gun is pulled out and clamped on the clamping seat 11. The moving box 2 is pushed into the groove 101. At the same time, the motor 502 is rotated in the reverse direction, so that on the one hand, the wire winding wheel 4 conveys the external cable into the moving box 2, and on the other hand, the multiple moving mechanisms 7 move intermittently and cooperate with the clamping assembly 8 to drive the cable to be arranged in a serpentine tube shape.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
