Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile capable of reducing cable wear. Background Art

[0002] The charging pile is used to provide electric power for electric vehicles and can be fixed on the ground or wall. The charging pile mainly provides current to the charging gun through the charging cable to realize the charging of the car. In order to meet the charging distances of different distances, the charging cable needs to be set to different lengths and convenient for winding. For example, a charging pile with reduced wear of charging cables, for example, is disclosed in CN118082567A, and includes a foundation, a pile body is provided on the top of the foundation, and a pneumatic auxiliary retracting mechanism is provided on the outside of the foundation. The pneumatic auxiliary retracting mechanism is used to assist in collecting and releasing the charging cable. The pneumatic auxiliary retracting mechanism includes Thick tube, thin tube, reel, charging cable, rotating shaft, wind plate; by adopting extrusion mechanism, air pressure assisted retracting mechanism, plug, locking mechanism, installation mechanism, etc.; it solves the problem that the charging cables of current charging piles are scattered on the ground and may trip pedestrians, dragging the charging cables during charging will accelerate the wear of the charging cables, and the plugs fall off. The linkage between the mechanisms can assist the charging pile to release and reel the charging cables in the charging and non-charging states, respectively, thus avoiding the problem of charging cables scattered on the ground, which not only ensures the safety of pedestrians, but also increases the service life of the charging cables;

[0003] For example, the publication number CN113103891B is a dustproof shared charging pile that can store and protect the wiring harness, including: a charging pile body; a wire-receiving mechanism, which is arranged on the inner side of the lower end of the charging pile body, and a motor is installed inside the lower end of the charging pile body, and the shaft end key of the motor is connected to a power gear; it is convenient to quickly store and protect the cables, increase the service life of the cables, reduce the incidence of safety accidents, and protect the operating panel to prevent dust adhesion. However, the above charging pile still has the following shortcomings in actual use:

[0004] 1. After the traditional charging cable is stretched, a long section of the cable is in direct contact with the ground, and the cable rubs against the rough ground during the dragging process, which will cause the cable surface to wear. This will cause cable damage and affect charging in the long run. Therefore, the cable of the traditional charging pile lacks a good protective structure;

[0005] 2. In addition, the length of the cable wrapped inside the charging pile is limited. When the cable is stretched excessively, it will cause the cable and the power transmission equipment to loosen. After being pulled by external force for a long time, the cable is likely to fall off. Therefore, there is a lack of a structure to sound an alarm when the cable is stretched excessively.

[0006] In response to the above problems, it is urgently necessary to carry out innovative designs based on the original charging piles. Summary of the invention

[0007] The purpose of the present invention is to provide a charging pile that can reduce cable wear, so as to solve the problem that the cables of traditional charging piles mentioned in the above background technology lack a good protective anti-wear structure and lack a structure to alarm after the cables are over-stretched.

[0008] To achieve the above object, the present invention provides the following technical solution: a charging pile capable of reducing cable wear, comprising a charging pile body, a charging gun is arranged on the side of the charging pile body, and the tail end of the charging gun is connected to the charging pile body through a charging cable, the charging cable is rolled up on the outside of the connecting shaft, and the charging cable is stored in a storage cavity, and the storage cavity is opened at the lower end of the charging pile body;

[0012] Preferably, the supporting mechanism includes a fixed cylinder sleeved on the outside of the charging cable, and a fixed block is fixedly sleeved in the middle position of the charging cable, and the outer diameter of the fixed block is smaller than the inner diameter of the holes on the worm gear and the protective box, and the outer diameter of the fixed block is larger than the inner diameter of the fixed cylinder. The charging cable can be supported by the fixed cylinder to prevent it from directly contacting the ground, and the fixed cylinder can be driven to move by the fixed block when the charging cable is continuously pulled.

[0013] Preferably, a support seat is fixed below the fixed cylinder, and a movable wheel is installed on the lower end surface of the support seat, and the support seat is fixedly connected to the side surface of the charging pile body close to the support seat and one end of the traction rope, while the other end of the traction rope slides through the charging pile body and is wound around the winding shaft, and the central axis of the fixed cylinder and the worm gear are on the same horizontal line. When the fixed cylinder is pulled, it drives the support seat to move and drives the wound traction rope to continue to extend.

[0014] Preferably, the reel is rotatably arranged inside the charging pile body, and a fixed cavity is opened in the charging pile body outside the reel, and a spiral spring is arranged at the rotation point of the reel and the charging pile body, and at the same time, two traction ropes are symmetrically arranged about the horizontal axis of the support seat.

The specific contents are as follows:

[0019] 1. When the connecting shaft rotates, it can drive the transmission shaft to rotate synchronously through the pulley mechanism, and then drive the worm wheel to rotate through the meshing transmission of the worm and the worm wheel. In this way, when the charging cable is rolled up, the cleaning brush can be driven by the rotation of the worm wheel to sweep the surface of the charging cable, sweeping away the dust and impurities adhering to the surface, and preventing dust from following the charging cable into the charging pile body;

When the charging cable is reeled in after use, the spiral spring on the reel shaft can drive it to rotate in the opposite direction, so as to reel in the traction rope, and then drive the support seat to approach the charging pile body through the moving wheel;

[0021] 3. When the charging cable is stretched to its limit during use, it can drive the movable rod to slide down in the fixed box, and then push the connecting rod to slide down on the fixed box synchronously. After the connecting rod descends, it can drive the fixing plate to contact the alarm, so that the alarm sounds an alarm to remind the user that the charging cable cannot be extended further to avoid damage to the charging cable.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0034] Embodiment 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a charging pile that can reduce cable wear, including a charging pile body 1, a charging gun 2 is arranged on the side of the charging pile body 1, and the tail end of the charging gun 2 is connected to the charging pile body 1 through a charging line 3, the charging line 3 is rolled up on the outside of the connecting shaft 4, and the charging line 3 is stored in the storage cavity 6, and the storage cavity 6 is opened at the lower end of the charging pile body 1; it also includes: a motor 5, whose output shaft is fixedly connected to one end of the connecting shaft 4, the motor 5 is installed inside the charging pile body 1, and the other end of the connecting shaft 4 is connected through a pulley mechanism and One end of the transmission shaft 7 is interconnected, and a worm 8 is fixed to the other end of the transmission shaft 7. A protective box 9 is sleeved on the outer side of the worm 8, and the protective box 9 is fixed to the front of the charging pile body 1. A worm wheel 10 is meshed and connected below the worm 8, and the side of the worm wheel 10 is interconnected with the inner wall of the protective box 9 through a retaining frame 11; a supporting mechanism is arranged on the side of the charging pile body 1, and the supporting mechanism has an anti-wear effect by supporting the charging cable 3, and the end of the charging cable 3 is fixedly connected to the inside of the connecting shaft 4 through a connecting cable 32, and a safety component is provided at the connection between the connecting cable 32 and the connecting shaft 4, and the safety component is used to prevent the charging cable 3 from being excessively stretched.

[0035] When the existing charging cable 3 is stretched out for use, dust and other impurities will adhere to its surface, and there is no structure to clean the surface of the charging cable 3 during the winding process, which causes dust to enter the charging pile and accumulate. Figure 1-Figure 5As shown, the worm wheel 10 forms a relative rotation structure through the inner wall of the retaining frame 11 and the protective box 9, and a circular hole is arranged inside the worm wheel 10, and a cleaning brush 12 is evenly arranged inside the hole, and the inner bottom surface of the protective box 9 is evenly reserved with fixing holes 13, and the fixing holes 13 are distributed below the worm wheel 10, and a partition plate is arranged between the worm wheel 10 and the pulley; when the charging gun 2 needs to be used to charge the car, the charging gun 2 is removed, and the motor 5 drives the connecting shaft 4 to rotate, so that the charging line 3 wound on the connecting shaft 4 can be extended to meet the charging requirements of different lengths, and the charging is completed The rear motor 5 is driven in reverse to realize the winding of the charging cable 3 through the connecting shaft 4. When the connecting shaft 4 rotates, it can drive the transmission shaft 7 to rotate synchronously through the pulley mechanism. The transmission shaft 7 drives the worm 8 to rotate. Through the meshing transmission of the worm 8 and the worm wheel 10, the worm wheel 10 is driven to rotate on the inner wall of the protective box 9 through the retaining frame 11. In this way, during the winding process of the charging cable 3, the rotation of the worm wheel 10 can drive the cleaning brush 12 to sweep the surface of the charging cable 3, sweeping off the dust and impurities adhered to its surface, and the dust can be discharged from the fixing hole 13, thereby preventing the dust from following the charging cable 3 into the inside of the charging pile body 1.

[0036] Embodiment 2: After the existing charging cable 3 is stretched, a long section of the charging cable 3 directly contacts the ground, and the charging cable 3 rubs against the rough ground during the dragging process, which will cause the surface of the charging cable 3 to be worn. This will cause damage to the charging cable 3 and affect charging in the long term. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 , Figure 6 and Fig. 9As shown, the support mechanism includes a fixed cylinder 14 sleeved on the outside of the charging cable 3, and a fixed block 31 is fixedly sleeved in the middle position of the charging cable 3, and the outer diameter of the fixed block 31 is smaller than the inner diameter of the holes on the worm gear 10 and the protective box 9, and the outer diameter of the fixed block 31 is larger than the inner diameter of the fixed cylinder 14; a support seat 15 is fixed below the fixed cylinder 14, and a moving wheel 16 is installed on the lower end surface of the support seat 15, and the support seat 15 is fixedly connected to the side of the charging pile body 1 close to the charging pile body 1 and one end of the traction rope 17, and the other end of the traction rope 17 slides through the charging pile body 1 and is wound around the winding shaft 18, and the central axis of the fixed cylinder 14 and the worm wheel 10 are on the same horizontal line; the winding shaft 18 is rotatably arranged inside the charging pile body 1, and a fixed cavity 19 is opened in the charging pile body 1 outside the winding shaft 18, and a spiral spring is arranged at the rotation of the winding shaft 18 and the charging pile body 1, and the traction rope 17 is about the support Two horizontal axes of the seat 15 are symmetrically arranged; the charging line 3 passes through the interior of the fixed cylinder 14, and when the charging line 3 is stretched, it can slide in the fixed cylinder 14. When the charging line 3 is extended by more than half, in order to avoid its hanging and contacting the ground, the fixed block 31 on the charging line 3 can pass through the worm gear 10 and the protective box 9 and contact the fixed cylinder 14, so that the fixed cylinder 14 can be pulled to move, driving the support seat 15 to move on the ground through the moving wheel 16. At this time, the wound traction rope 17 is pulled and continuously extended, which facilitates the continuous movement of the fixed cylinder 14 to support the subsequent stretched charging line 3, and prevents the charging line 3 from being worn by friction with the ground. When the charging line 3 is wound up after use, the fixed block 31 no longer pulls the fixed cylinder 14, so that the spiral spring on the winding shaft 18 can drive it to rotate in the opposite direction, so as to realize the winding of the traction rope 17, and then the support seat 15 can be driven to approach the charging pile body 1 through the moving wheel 16 for the next use.

[0037] Embodiment 3: Since the length of the charging cable 3 wound inside the charging pile is limited, when the charging cable 3 is stretched excessively, it will cause the charging cable 3 to loosen from the power transmission equipment, and the charging cable 3 is easily pulled off after being pulled by external force for a long time. Therefore, there is no structure for alarming after the charging cable 3 is stretched excessively. Therefore, this embodiment adopts the following technical solutions, such as Figure 7-Figure 8As shown, the safety component includes a fixed box 20 fixed on the connecting shaft 4, and the inner wall of the fixed box 20 is respectively provided with a fixed rod 21 and a movable rod 22, and the fixed rod 21 and the fixed box 20 are fixedly connected, and the movable rod 22 and the fixed box 20 form a relative lifting structure; a connecting rod 23 is fixed to the lower side of the movable rod 22, and the connecting rod 23 slides through the inner bottom surface of the fixed box 20, and the lower end of the connecting rod 23 is wound with a spring for resetting it, and the connecting line 32 is wound in an "S" shape on the outside of the fixed rod 21 and the movable rod 22; a fixed plate 24 is fixedly sleeved on the outside of the connecting rod 23, an alarm 25 is installed on the inner bottom surface of the fixed box 20, and the fixed box 20 is directly below the fixed plate 24. When the charging cable 3 is stretched to its limit during use, the connecting cable 32 can be pulled. The connecting cable 32 is arranged in an "S" shape in the fixing box 20 and thus has a stretchable range. When the connecting cable 32 is pulled, the movable rod 22 can be driven to slide down in the fixing box 20, thereby pushing the connecting rod 23 to slide down synchronously on the fixing box 20. After the connecting rod 23 descends, the fixing plate 24 can be driven to contact the alarm 25, so that the alarm 25 sounds an alarm to remind the user that the charging cable 3 cannot be extended further to avoid damage to the charging cable 3. When the charging cable 3 stops extending further, the connecting cable 32 is not pulled, and the connecting rod 23 and the movable rod 22 can be driven to rise through the resilience of the spring, thereby protecting the connecting cable 32.
