Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a new energy vehicle charging pile with a protection function. Background Art

[0002] The new energy charging pile is a device that provides energy replenishment for electric vehicles. The charging pile mainly includes a pile body, a charging module, a display screen, a connecting cable and a safety protection device. Among them, the charging module is the core component, which is responsible for the conversion and transmission of electric energy, and the safety protection device includes leakage protection, overcurrent protection, etc. to ensure safe use. The new energy charging pile inputs AC power through the power grid, which is converted into DC power by the rectifier circuit, and then the DC-DC converter outputs the required DC voltage to charge the electric vehicle. This process requires a controller to adjust and protect to ensure safety and efficiency. The existing charging piles have a wide range of application scenarios. For example, the charging piles installed in urban public parking lots have charging guns and cables that are confined in a protective box and isolated from the external environment. In this way, the charging guns and cables can be prevented from being easily aged, broken or damaged due to long-term exposure to the external environment, thereby affecting normal use. The rotating plate squeezes the first pressing plate downward, so that the connecting rod drives the push block to push the limit block downward, so that the protection box flips upward. In this way, the automatic flipping of the protection box can be realized, making the use of the device more convenient.

[0003] Although the existing charging piles have a protection function, the charging gun and the cable are generally protected by a protection box. However, in actual use of the existing charging piles, when the charging gun is in use, most users take out the charging gun from the protection box and pull it, pulling out the charging gun and the cable together. However, the protection box lacks a reminder for pulling the cable. Some users tend to drag the cable violently in the protection box when taking it out, resulting in fatigue between the end of the cable and the charging box due to long-term dragging, thereby causing disconnection between the cable and the charging box, affecting the normal use of the charging pile and reducing the protection effect of the charging pile.

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] The present invention provides Figure 1-Figure 6 A new energy vehicle charging pile with a protective function shown in the figure comprises: a charging pile body 1, a protection box 12 is fixed on one side of the charging pile body 1, a cable 14 is installed in the protection box 12, an outlet 15 for the cable 14 to slide is opened on one side of the protection box 12, and one end of the cable 14 passes through the outlet 15 and is fixed with a charging grab 13, and one end of the charging grab 13 is pluggably installed on one side of the charging pile body 1;

[0040] The protection component 2 is used to prompt the cable 14 in the protection box 12. The protection component 2 includes two metal shells 21 symmetrically fixed in the protection box 12, a guide plate 22 installed in the protection box 12, and a guide groove 23 provided on one side of the guide plate 22 for the cable 14 to slide. The outsides of the two metal shells 21 are fixed with mounting frames 26. The two metal shells 21 are provided with a reeling component 4 for winding the cable 14. The tops of the two mounting frames 26 are both installed with a slidable moving block 27, and one side of the two mounting frames 26 is installed with a driving mechanism for driving the two mounting frames 26. A reciprocating assembly 3 is provided with two moving blocks 27 for sliding, a metal block 28 is fixed at one end of each of the two moving blocks 27, and one end of each of the two metal blocks 28 collides with the outside of the two metal shells 21, a rotatable connecting rod 25 is installed in each of the two mounting frames 26 and the guide plate 22, a first roller 24 for driving the two connecting rods 25 to rotate is installed in the guide groove 23, and the outside of the first roller 24 conflicts with the outside of the cable 14, a limiting assembly 5 for limiting the cable 14 is provided in the guide groove 23, and a supporting assembly 6 for supporting the connecting rod 25 is provided on the mounting frame 26.

[0041] The reciprocating assembly 3 includes a connecting column 32 fixed to the middle of the bottom of the mounting frame 26, a second reciprocating column 36 fixed to one side of the moving block 27, and a swing arm 33 rotatably sleeved on the connecting column 32, and a second reciprocating groove 35 for the second reciprocating column 36 to slide is provided at the top of the swing arm 33, a circular ring is fixed at one end of the connecting rod 25, and one end of the circular ring extends to the outside of the mounting frame 26 and is fixed with the first reciprocating column 31, and a first reciprocating groove 34 for the first reciprocating column 31 to slide is provided at the bottom of the swing arm 33;

[0042] When the charging pile is in use, first park the car near the charging pile body 1, then pull out the charging grab 13 on one side of the charging pile body 1, and press the reel assembly 4 to rotate the cable 14 along its outside, thereby pre-limiting the cable 14, and pulling the charging grab 13 drives the cable 14 to slide out of the protection box 12 and the outlet 15, and then the cable 14 generates friction with the outside of the first roller 24 when moving, and the first roller 24 rotates in the guide groove 23. At this time, the rotation of the first roller 24 drives the connecting rod 25 to rotate, but the connecting rod 2 The rotation of the ring drives the rotation of the ring, and the rotation of the ring drives the first reciprocating column 31 to rotate. As the first reciprocating column 31 rotates, it slides downward along the first reciprocating groove 34 and pushes the swing arm 33 to slide. Then the swing arm 33 rotates along the outside of the connecting column 32, so that the first reciprocating groove 34 slides horizontally on one side of the mounting frame 26. Then, the first reciprocating groove 34 slides between the second reciprocating groove 35 opened at its top and the second reciprocating column 36 and pushes the second reciprocating column 36 to move, so that the moving block 27 slides on the mounting frame 26, and the metal block 28 slides to the side of the metal shell 21 and moves it. A collision occurs, thereby emitting a crisp sound, which is used to give the user the first reminder. At this time, the length of the first layer of the cable 14 is completely pulled out, and the remaining part is still entangled to avoid affecting the connection end of the cable 14 and the charging pile body 1. Secondly, when the remaining part of the cable 14 needs to be taken out, continue to pull the cable 14, so that a second collision or a third collision occurs between the metal block 28 and the metal shell 21. The length of the cable 14 taken out during each collision is different, which is convenient for the user to pull the cable 14 slowly and orderly. The remaining part is still in a tangled state, and after the cable 14 is taken out to a suitable length, the reeling component 4 can be pressed again to wind up the remaining part of the cable 14 and prevent it from being pulled out, thereby completing the insertion between the charging gun 13 and the car, and charging the car, so that it can serve as a reminder when the cable 14 is pulled out of the protective box 12, which is beneficial for the user to slow down the pulling speed of the cable 14, and can avoid the cable 14 being pulled violently for a long time and fatigue disconnection between the charging pile body 1, thereby improving the protection effect of the charging pile body 1.

[0043] Furthermore, a limiting groove 29 is provided at the top of the mounting frame 26, a triangular block is fixed at the bottom end of the movable block 27, and the triangular block is slidably connected to the limiting groove 29; based on this, the setting of the limiting groove 29 is conducive to guiding the movable block 27, and can prevent the movable block 27 from being offset when sliding on the mounting frame 26, so that the metal block 28 and the metal shell 21 can collide accurately.

[0044] refer to Figure 1-Figure 4As shown, the winding assembly 4 includes two winding seats 41 fixed on one side of the two metal shells 21 and a winding frame 42 rotatably installed between the two winding seats 41, and the surface of the winding frame 42 is used to wind and organize the cable 14, one end of one of the winding seats 41 extends to the outside of the metal shell 21 and is sleeved with a fixed disk 43, and a bolt 44 is screwed between the fixed disk 43 and one of the metal shells 21, a drive motor 45 is installed at one end of the fixed disk 43, and the drive motor 45 is used to drive the winding frame 42 to rotate, a control panel 46 is fixed to one side of the protective box 12, and the control panel 46 is used to control the forward and reverse rotation of the drive motor 45; another winding seat 41 and another metal shell 21 are also provided with a lock hole 47 for inserting the cable 14, and the diameter of the lock hole 47 is adapted to the cable 14.

[0045] Through the above technical solution:

[0046] When the cable 14 is not in use, the cable 14 can be wound and rolled up in the protective box 12 through the winding assembly 4 as a whole, ensuring that the cable 14 is stored in the protective box 12 in an orderly manner, avoiding the cable 14 from being exposed to the outside world and possibly being squeezed or damaged by vehicles or other objects, which is beneficial to the protection of the cable 14. At the same time, for users, the cable 14 is often thick and heavy, and users will feel strenuous when using it. Therefore, the winding assembly 4 can greatly reduce the burden on users, making the charging process easier and ensuring the normal use of the charging pile body 1.

[0047] When the cable 14 is in use, the user first operates the control panel 46 to control the start, stop or forward and reverse rotation of the drive motor 45, and rotates the drive motor 45 along one of the reel seats 41, and then drives the reel frame 42 to rotate between the two reel seats 41. At this time, the user takes out the charging gun 13 and approaches the car. During the movement, the user pulls the cable 14 to slide it along the outside of the reel frame 42, so that the cable 14 slides outward in the outlet 15, which is used to take out part of the cable 14, which is beneficial to extend the length of the charging gun 13 and facilitate the insertion of the charging gun 13 into the charging port of the car. , the rest of the part is still wound around the reel 42 and the other reel 41, and after insertion, the user returns to the charging pile body 1, and operates the control panel 46 again to stop the driving motor 45, but the driving motor 45 is still in working state on the way back, and the cable 14 can be continuously released, so that the cable 14 can be kept in a relaxed state at the part taken out, avoiding the pulling between the cable 14 and the charging grab 13 caused by the tension, which is conducive to the good stability between the charging grab 13 and the car, so that the car can maintain normal charging, and further improve the protection effect of the charging pile body 1;

[0048] Not only can the cable 14 be wound and rolled on the winding rack 42 and arranged in the protective box 12, but the speed of taking out the cable 14 on the winding rack 42 can also be slowed down, which can prevent the cable 14 from being pulled suddenly and causing fatigue between it and the charging pile body 1, thereby ensuring the normal use of the cable 14 and further improving the protection effect of the charging pile body 1.

[0049] refer to Figure 3 , Figure 7 and Figure 8 As shown, the limit assembly 5 includes a limit frame 51 that can be extended and lowered and installed in the guide groove 23, and a second roller 52 that can be rotatably installed in the limit frame 51, and the outer part of the second roller 52 contacts the outer part of the cable 14, and a retractable telescopic column 54 and a spring 53 are fixed between the limit frame 51 and the guide groove 23, and the spring 53 is sleeved on the outer part of the telescopic column 54; a guide groove 55 is also provided on one side of the limit frame 51, and a guide rod 56 corresponding to the guide groove 55 is fixed in the guide groove 23, and the guide rod 56 is slidably connected to the guide groove 55.

[0050] Through the above technical solution:

[0051] When the cable 14 is taken out, the cable 14 first slides between the first roller 24 and the second roller 52, and the outside of the cable 14 contacts the outside of the second roller 52, and then the second roller 52 pushes the limit frame 51 to slide upward. At this time, the limit frame 51 slides upward to slide between the guide groove 55 and the guide rod 56 provided on its outside, which is used to limit the movement of the limit frame 51 to ensure that the limit frame 51 moves upward stably, and the limit frame 51 moves upward to squeeze the telescopic column 54 and the spring 53, and the spring 53 is tightened and reset. By giving a thrust to one side of the limit frame 51, the limit frame 51 is pushed downward, so that the second roller 52 and the cable 14 are stably in contact with each other, so that the second roller 52 and the outside of the cable 14 have an adaptive force, and the second roller 52 is in contact with the outside of the cable 14 without being too tight, so that the cable 14 can slide out between the second roller 52 and the first roller 24, and the cable 14 can be limited during the winding or pulling process, so as to prevent the cable 14 from being excessively twisted during the sliding process, thereby adding additional protection to the cable 14 and extending its service life.

[0052] refer to Figure 3 and Fig. 9As shown, the support assembly 6 includes an arc-shaped bracket 62 installed on the outside of the connecting rod 25 and a support frame 61 screwed to the bottom of the mounting frame 26, and a fixing rod 63 is fixed to the bottom of the arc-shaped bracket 62, and a pin slot 65 for inserting the fixing rod 63 is provided at the top of the support frame 61, and threaded holes 64 are provided on the fixing rod 63 and the support frame 61, and the threaded holes 64 are communicated with the inside of the pin slot 65, and a threaded column 66 is screwed in the threaded hole 64; a positioning column 67 is also fixed to the side of the arc-shaped bracket 62 adjacent to the fixing rod 63, and a positioning slot for inserting the lock hole 47 is provided at the top of the support frame 61.

[0053] Through the above technical solution:

[0054] Before the connecting rod 25 is used, the fixing rod 63 is first inserted into the latch groove 65, and then the fixing rod 63 slides downward along the latch groove 65. At this time, the positioning column 67 is inserted into the positioning groove, and the arc bracket 62 is pressed to push the fixing rod 63 and the positioning column 67 to continue to slide downward along the latch groove 65 and the positioning groove. The positioning column 67 first contacts the positioning groove, and then the threaded hole 64 opened on the fixing rod 63 coincides with the threaded hole 64 opened on the support frame 61. Then, the threaded column 66 is screwed with the threaded hole 64, and the arc bracket 62 is screwed to the support frame 6 1, ensure the stability of the arc bracket 62, then fit the inside of the arc bracket 62 with the outside of the connecting rod 25, and then screw the support frame 61 and the mounting frame 26 to ensure that the arc bracket 62 and the connecting rod 25 are stably fitted. At this time, the arc bracket 62 supports and limits the middle position of the connecting rod 25 in the hollow state. Being able to support the outside of the connecting rod 25 can reduce the stress on the connecting rod 25, ensure the stability of the connecting rod 25 in the support assembly 6, improve the stable movement of the cable 14, and further enhance the protection effect of the charging pile body 1.
