At the same time, the second magnet 27 will use the principle of like charges repelling each other. The first magnet 26 is pushed downward by the magnetic force, so that the first magnet 26 drives the guide sleeve 25 to move downward along the movable hole 22, and then the guide sleeve 25 and the first magnet 26 push the blocking rod 23 under the action of external force, so that the blocking rod 23 moves horizontally along the guide groove 41 in the direction away from each other, and stretches the spring 24, so that the blocking rod 23 passes through the guide groove 41 and moves out to the outside, so that the battery car 11 can resist the blocking rod 23, and the blocking rod 23 prevents the cone rod 20 from moving out of the socket 12, so that the converter 1 can be installed on the battery car 11 more stably. At the same time, the shield 10 will drive the frame plate 37 to move downward during the downward movement, and fit with the pressure plate 15, so that the shield 10 and the frame plate 37 use the clearance groove 28 to cover the first bolt 14 and the second bolt 16 away from one end of the battery car 11, thereby providing protection for the first bolt 14, the second bolt 16 and the converter 1, increasing the difficulty of theft and playing an anti-theft role.

[0126] The staff can move the pull ring 35 after the pull rope 33 is pulled out through the handle rod 36 according to the actual needs, so that the pull ring 35 is inserted into the inner side of the socket 38, and the pull ring 35 is pushed toward the direction close to the guard plate 39 through the handle rod 36, so that the pull ring 35 passes through the socket 38 and is inserted into the inner side of the guide groove 41. Then, as the pull ring 35 is inserted into the inner side of the guide groove 41, the arc plate 42 is gradually pushed downward by the external force and the contours of the pull ring 35 and the arc plate 42, so that the arc plate 42 passes through the guide groove 41 and moves downward, and the elastic plate 43 is pushed to deform by the external force under the support of the frame plate 37, so that the arc plate 42 is close to the guard plate 39. One side of the inner wall of the socket 38 can be moved downward out of the guide groove 41. At the same time, the staff needs to pull the frame plate 37 in the direction away from the protective cover 10, so that the frame plate 37 uses external force to pull the arc plate 42 through the elastic plate 43, so that the arc plate 42 uses external force and its own curvature to contact the protective plate 39, and uses the external force and the resistance of the protective plate 39 to push the elastic plate 43 along the arc surface of the arc plate 42 to continue to deform, so that the arc plate 42 is completely moved out of the guide groove 41, and then the connection between the frame plate 37 and the protective cover 10 is released, so that the frame plate 37 is removed to open the opening of the protective cover 10, and then the converter 1 is exposed to facilitate maintenance by the staff.

[0134] A T rod 34, fixed to an end of the screw rod 13 away from the first bolt 14;

[0135] A pull rope 33 is wound around the outside of the T-bar 34;

[0136] The herringbone rope 31 is connected to one end of the pull rope 33 away from the T rod 34 .

[0137] In the actual application of this embodiment, the screw rod 13 can provide a stable support for the T rod 34, and the T rod 34 can provide a winding space for the pull rope 33. The pull rope 33 can be bent and deformed arbitrarily under the action of external force. The herringbone rope 31 can pull the pull rope 33 through the cone head 32, and the setting of the cone head 32 can facilitate the pull rope 33 to be broken from the position where it is connected with the cone head 32. The pull rope 33 can pull the T rod 34 to rotate under the action of external force. When the pull rope 33 is separated from the T rod 34 and passes through the sleeve rod 30 and moves out to the outside, the staff needs to move in the opposite direction Pull the herringbone rope 31 and the pull rope 33 to separate the pull rope 33 from the cone head 32, so as to facilitate the storage of the pull ring 35, the herringbone rope 31 and the handle rod 36. The sleeve rod 30 can provide support for the connecting sleeve 29 under the support of the guard plate 39. The connecting sleeve 29 can provide support for the second wire 5, and can prevent the external force generated by the pulling of the second wire 5 from being transmitted to the first wire 4, and prevent the connection between the first wire 4 and the second wire 5 and the converter 1 from being broken by external force, thereby providing protection for the first wire 4 and providing a penetration space for the pull rope 33, the cone head 32 and the herringbone rope 31.

[0138] Working principle: During installation, the staff needs to rotate the first bolt 14 under the support of the bearing to make it tightly connected with the thread of the battery car 11. At the same time, the bearing provides support for the pressure plate 15 and the second bolt 16, and can provide rotation support for the second bolt 16. When the first bolt 14 is connected to the battery car 11, the pressure plate 15 will push the second bolt 16 to be threadedly connected to the installation position of the battery car 11 to further ensure the tightening effect. The entire installation process is to insert the cone rod 20 into the socket 12 on the battery car 11, and through the magnetic force of auxiliary parts and magnetic push parts (including guide sleeve 25 and magnet), auxiliary support and fixation of the converter 1.

[0139] The battery of the battery car 11 is connected to the input end of the converter 1 through the input plug 6, and the power is transmitted to the inside of the converter 1 through the second wire 5, and the converter 1 provides a stable voltage output for the motor and other electronic equipment of the battery car 11. The output plug 7 is connected to the output end of the converter 1 to ensure the normal operation control of the motor and other electronic equipment of the battery car 11, such as starting, stopping, and speed adjustment.

[0140] To prevent overheating, heat sink fins 2 and heat-conducting copper plates 8 are installed on the outside of the converter 1. The copper plates conduct the heat generated by the converter 1 to the heat sink fins 2. Two fans 9 are fixed on the heat-conducting copper plates 8. The heat is discharged to the outside through the protective cover 10 during operation, ensuring that the converter 1 maintains a low temperature when working for a long time.

[0141] The shield 10, the guard plate 39 and the frame plate 37 can protect the converter 1 from the threat of theft when the battery vehicle 11 is parked. Through the action of the threads, the shield 10 and the guard plate 39 cover the installation components, making disassembly difficult. In addition, the use of the magnetic system and the repulsive force between the magnets make the installation of the converter 1 more solid and stable. At the same time, the design of the shield 10 blocks the direct contact of the disassembly bolts, thereby improving the anti-theft effect.

[0142] The staff can unlock the cover 10 through the pull ring 35, the handle rod 36 and other components, and can conveniently inspect and maintain the converter 1 after opening the cover 10.

[0143] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
