A new energy vehicle charging pile socket

Abstract

The present invention discloses a new energy vehicle charging pile socket, including a mounting column and an electrical connection mechanism. The electrical connection mechanism includes a fixing seat, a hinge, a limiter, a first conductive wire and a second conductive wire. The fixing seat is composed of a bearing portion, a connecting portion and a retaining portion, and the limiter applies pressure on the first conductive wire through the elastic force of an elastic member. The new energy vehicle charging pile socket pushes the limiter to apply pressure through the elastic force of the elastic member to ensure that the limiter protrusion cooperates with the limiter recess on the first conductive wire, thereby limiting the position of the first conductive wire, so that the charging wire will not easily become loose when it is accidentally pulled, and can ensure the stable electrical connection of the charging wire and improve the strength of the entire charging pile. At the same time, the adjusting member is rotated so that the threaded sleeves are close to each other, and the movable rod limits the elastic compression of the elastic member, thereby locking the pressing member and the hinge, and improving the limiting strength of the limiter on the first conductive wire.

Description

While personal or public charging piles bring convenience to consumers, they generally have defects. When car owners take the charging gun to connect it to the car charging port, they will pull the charging cable connected to the charging gun to a certain extent, which will make the electrical connection structure between the charging cable and the charging pile loose, affecting the electrical connection effect. As time goes by and the number of times it is pulled increases, the connection of the charging cable will eventually become loose, resulting in poor contact, etc., which will affect the charging of the car and reduce the stability of the entire charging pile.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0042] like Figures 1 to 17 As shown, the new energy vehicle charging pile socket of the present invention includes a mounting column 1 and an electrical connection mechanism 2. A charging box 3 is provided on the mounting column 1, a connector 4 is provided at the lower end of the charging box 3, a charging line 5 is provided on the connector 4, and a charging gun 6 is provided at the other end of the charging line 5, and the charging gun 6 is hung on one side of the charging box 3. The mounting column 1 is used to install the charging box 3 on the ground, and the electrical connection mechanism 2 is used to connect the connector 4 of the charging line 5 with the external power supply inside the charging box 3. The electrical connection mechanism 2 can not only realize a stable electrical connection between the charging line 5 and the internal external power supply of the charging box 3, but also ensure that the connector 4 of the charging line 5 and the external power supply of the charging box 3 will not loosen when the charging line 5 is pulled, thereby improving the electrical connection strength between the charging line 5 and the charging box 3, which is beneficial to improving the quality and service life of the entire charging pile 7.

[0043] The electrical connection mechanism 2 is arranged in the charging box 3, and the electrical connection mechanism 2 remains connected to the connector 4. The electrical connection mechanism 2 includes a fixing seat 8, a hinge 9, a limiter 10, a first conductive wire 11, and a second conductive wire 12. The fixing seat 8 is installed inside the charging box 3 so that the fixing seat 8 is fixedly connected to the charging box 3 to ensure the installation strength of the fixing seat 8. The hinge 9 is used to lift the limiter 10 so that the limiter 10 no longer applies pressure to the first conductive wire 11. The second conductive wire 12 remains connected to the external power supply, and then is connected to the first conductive wire 11 through the conductive member 13.

[0044] The fixing seat 8 is composed of a bearing portion 14, a connecting portion 15 and a retaining portion 16. The bearing portion 14 and the retaining portion 16 are connected via the connecting portion 15. The connecting portion 15 is arranged on both sides of the bearing portion 14 and the retaining portion 16, so that the middle of the bearing portion 14 and the retaining portion 16 is convenient for the installation of the limit member 10, the elastic member 17, the hinge seat 18 and the adjusting member 19.

[0045] The lower end of the bearing portion 14 is provided with symmetrical mounting feet 20, and the mounting feet 20 are used to mount the fixing seat 8 inside the charging box 3. The bearing portion 14 is provided with symmetrical mounting grooves 21, and the mounting grooves 21 are used to mount the first conductive wire 11, the second conductive wire 12 and the conductive member 13, so that the first conductive wire 11 and the second conductive wire 12 are electrically connected in the mounting grooves 21.

[0046] A limiting surface 22 is provided between the mounting grooves 21, and the limiting surface 22 is used to limit the descending height of the limiting protrusion 23. An active area 24 is formed between the bearing portion 14 and the holding portion 16, and the active area 24 is connected to the mounting groove 21. A sinking groove 25 is provided at the upper end of the holding portion 16, and a pressing member 26 is provided at the upper end of the sinking groove 25. When the pressing member 26 is pressed by an external force, the pressing member 26 enters the sinking groove 25. Two active chambers 27 are provided in the middle of the holding portion 16, and the active chambers 27 connect the sinking groove 25 with the active area 24.

[0047] The hinged member 9 is arranged in the movable chamber 27, a first hinge hole 28 is arranged in the middle of the movable chamber 27, a first hinge rod 29 is arranged in the first hinge hole 28, a first hinge portion 30 is arranged in the middle of the hinged member 9, and the first hinge rod 29 is installed in the middle of the first hinge portion 30. A second hinge portion 31 is arranged at the upper end of the hinged member 9, and a second hinge rod 32 is arranged in the middle of the second hinge portion 31. A pressing member 26 is arranged on the second hinge rod 32, and the pressing member 26 is hingedly connected to the second hinge rod 32. A third hinge rod 33 is arranged at the lower end of the hinged member 9.

[0048] An arc-shaped area 34 is provided in the middle of the activity chamber 27, and the first hinge portion 30 is installed in cooperation with the arc-shaped area 34. An upper activity space 76 is formed at the upper end of the activity chamber 27, and a lower activity space 77 is formed at the lower end. The upper activity space 76 and the lower activity space 77 are rotationally symmetrically arranged around the first hinge hole 28, and the activity chamber 27 is in an inclined state.

[0049] When the hinge 9 is installed in the movable chamber 27 through the first hinge rod 29, the upper end of the hinge 9 is pressed by the pressing piece 26, which causes the upper end of the hinge 9 to rotate downward and enter the sink 25, while the lower end of the hinge 9 rotates upward and drives one end of the limit piece 10 hinged to the lower end of the hinge 9 to lift up, thereby causing the other end of the limit piece 10 to compress the elastic piece 17.

[0050] The elastic member 17 is composed of a mounting section 35, an elastic section 36 and a contact section 37. The mounting section 35 is provided with a through hole 38, and a bolt 39 is installed in the through hole 38. The bolt 39 can not only mount the elastic member 17 and the hinge seat 18 on the bottom surface of the retaining portion 16, but also because the bolt 39 is installed from the elastic region 40, the compressed stroke of the elastic member 17 can be limited by the bolt 39, that is, the distance of the contact section 37 close to the mounting section 35 is limited, thereby avoiding the elastic member 17 from being compressed and deformed. The elastic section 36 is arranged in an arc shape, and an elastic region 40 is formed between the mounting section 35, the elastic section 36 and the contact section 37, and the mounting section 35 is in contact with the hinge seat 18.

[0051] The contact section 37 is provided with an arc groove 41, the arc angle of the arc groove 41 is a major arc, a roller 42 is provided in the arc groove 41, and the roller 42 is arranged on the stopper 10. By placing the roller 42 on the plate 43 of the stopper 10, the friction between the contact section 37 and the plate 43 can be reduced.

[0052] The limiting member 10 is arranged in the movable area 24. The limiting member 10 is provided with a symmetrically arranged third hinge part 44. A movable groove 45 is formed between the third hinge part 44 and the third hinge part 44. The movable groove 45 is used for the lower end of the hinge member 9 to move therein. A third hinge hole 46 is provided in the middle of the third hinge part 44 to cooperate with the third hinge rod 33. The third hinge hole 46 is a strip hole, so that the third hinge rod 33 can move in the third hinge hole 46, thereby driving one end of the limiting member 10 to move upward. The limiting member 10 is also provided with a symmetrically arranged elastic member 17. The elastic member 17 is arranged at one end away from the third hinge part 44, that is, the third hinge part 44 is arranged at one end of the limiting member 10, and the elastic member 17 is arranged at the other end of the limiting member 10. A hinge seat 18 is provided at the upper end of the elastic member 17. The elastic member 17 and the hinge seat 18 are mounted on the lower end surface of the retaining portion 16 through bolts 39.

[0053] The lower end of the limiting member 10 is provided with a plurality of limiting protrusions 23, which are sawtooth-shaped and are composed of an inclined guide surface 47 and a vertical blocking surface 48.

[0054] The first conductive wire 11 and the second conductive wire 12 are arranged in the installation groove 21, the second conductive wire 12 is provided with a conductive member 13, the first conductive wire 11 is installed on the conductive member 13, and the limiting member 10 is pressed on the first conductive wire 11 by the elastic force of the elastic member 17. The first conductive wire 11 and the second conductive wire 12 are both composed of a cylindrical portion 49, a bridge portion 50 and an elliptical portion 51. The elliptical portion 51 on the first conductive wire 11 is provided with a limiting recess 52 that cooperates with the limiting protrusion 23, and the limiting recess 52 is composed of an inclined contact surface 53 and a vertically arranged limiting surface 54, the contact surface 53 contacts the guide surface 47, and the limiting surface 54 contacts the blocking surface 48.

[0055] A threaded hole 55 is provided in the mounting groove 21 , and a fastening bolt 56 is provided in the threaded hole 55 . When the fastening bolt 56 is tightened, the conductive member 13 and the first conductive line 11 can be pushed into close contact, thereby strengthening the electrical connection.

[0056] Before installation, the first conductive wire 11 and the second conductive wire 12 need to be stamped by stamping equipment at their ends, so that the cross-sections of the ends of the first conductive wire 11 and the second conductive wire 12 form three different shapes, namely, circular, skew and elliptical. Since the elliptical portion 51 has a long lateral distance, multiple limiting recesses 52 can be opened on it, so that it is convenient to cooperate with the limiting member 10 for limiting. Of course, the elliptical portion 51 on the second conductive wire 12 does not need to be opened.

[0057] The second conductive wire 12 needs to be installed with a conductive member 13 to facilitate electrical connection with the first conductive wire 11. The conductive member 13 is composed of an arc segment 57 and a wrapping segment 58. The arc segment 57 is provided with a receiving area 59, the wrapping segment 58 is provided with a fastening groove 60, and the middle of the wrapping segment 58 is provided with a wrapping area 61. The elliptical portion 51 on the first conductive wire 11 is arranged in the receiving area 59, and the elliptical portion 51 on the second conductive wire 12 is arranged in the wrapping area 61. When the second conductive wire 12 is placed in the middle of the wrapping segment 58, the wrapping segment 58 is pressed against the elliptical portion 51 on the second conductive wire 12, so that the conductive member 13 is stably installed on the second conductive wire 12.

[0058] The articulated seat 18 is composed of a curved plate 62 and fixed plates 63 arranged on both sides of the curved plate 62. An arc-shaped depression 78 is formed in the middle of the curved plate 62. A symmetrical first articulated block 64 is arranged on the lower end surface of the curved plate 62. An arc-shaped depression 65 is arranged on the retaining portion 16 to cooperate with the curved plate 62. The curved plate 62 is used to lengthen the distance between the articulated seat 18 and the adjusting member 19, facilitate the movement of the movable rod 66, and increase the movable stroke between the limiting member 10 and the articulated seat 18.

[0059] The limiting member 10 is composed of a plate body 43, and a mounting seat 67 is provided on the limiting member 10. The mounting seat 67 is arranged on the plate body 43, the third hinge part 44 is arranged on the plate body 43, and the limiting protrusion 23 is arranged on the lower end surface of the plate body 43. The mounting seat 67 is arranged between the symmetrical elastic members 17, and a mounting hole 68 is arranged in the middle of the mounting seat 67. The adjusting member 19 is arranged in the mounting hole 68. The adjusting member 19 is composed of a rotating section 69 and a first threaded portion 70 and a second threaded portion 71 arranged at both ends of the rotating section 69. The thread directions of the first threaded portion 70 and the second threaded portion 71 are opposite, and a threaded sleeve 72 is provided on the first threaded portion 70 and the second threaded portion 71, and a second hinge block 73 is provided on the threaded sleeve 72. The first hinge block 64 and the second hinge block 73 are hingedly connected through a movable rod 66. Adjustment disks 74 are provided at both ends of the adjusting member 19, and an adjustment hole 75 for installing the adjusting member 19 is provided on the connecting portion 15.

[0060] When the movable rod 66 is in the tilted state, the elastic member 17 can be compressed. When the elastic member 17 is compressed, the two ends of the movable rod 66 are respectively hinged on the first hinge block 64 and the second hinge block 73. When the adjusting disk 74 is rotated, the two threaded sleeves 72 on the adjusting member 19 are moved toward the middle, but the position of the first hinge block 64 does not move, so the second hinge block 73 pushes the movable rod 66, so that the adjusting member 19 pushes the limiter 10 downward, keeping the elastic member 17 slightly stretched, so that the movable rod 66 gradually changes from the tilted state to the vertical state, thereby limiting the compression of the elastic member 17, thereby preventing the limiter 10 from being lifted up by the hinge 9, and ensuring the stable installation of the first conductive wire 11.

[0061] Before the first conductive wire 11 is inserted into the installation groove 21 and contacts the conductive member 13 for installation, the pressing member 26 needs to be pressed first, so that the pressing member 26 enters the sinking groove 25, so that the lower end of the hinge 9 is lifted, driving the limiting protrusion 23 on the limiting member 10 to move upward, and compressing the elastic member 17 at the same time, and then inserting the first conductive wire 11 into the conductive member 13. Then, the external force on the pressing member 26 is cancelled, so that the hinge 9 is reset under the elastic force of the elastic member 17, and pressure is applied on the first conductive wire 11, so that the limiting protrusion 23 is placed in the limiting recess 52. At this time, since the limiting protrusion 23 is located at the lower end of the plate body 43, the lower end surface of the plate body 43 will not contact the bearing portion 14, and the limiting protrusion 23 will not contact the limiting surface 22, unless the limiting member 10 and the hinge 9 undergo transitional deformation, which will cause the limiting protrusion 23 to press the first conductive wire 11 to undergo transitional deformation, and then the limiting protrusion 23 will be limited by the limiting surface 22.
