[0028] Embodiment 1

[0029] Refer to Figures 1-4 , which is the first embodiment of the present utility model, provides a lead-acid battery cover for an electric power-assisted vehicle. Such a lead-acid battery cover for an electric power-assisted vehicle includes a battery cover 1. A convex edge 11 is fixed at a position near the bottom of the four sides of the battery cover 1. A vertical bin 12 is installed at the top of the battery cover 1, and a side bin 15 is integrally formed and connected to one side of the vertical bin 12. A bin cover 13 is fixed between the tops of the vertical bin 12 and the side bin 15;

[0030] Terminal assemblies 2 are inserted and installed on both sides of the top of the battery cover 1 and located on both sides of the side bin 15. Protection assemblies 3 for shielding the terminal assemblies 2 are installed on both sides inside the vertical bin 12. Inlet and outlets 14 for the movable ends of the protection assemblies 3 to pass through are opened between the adjacent surfaces of the vertical bin 12 and the side bin 15.

[0031] The protection component 3 includes two linear motors 31 installed on both sides inside the vertical bin 12. A connecting frame 32 is fixedly connected to the movable end of the linear motor 31. A protection shield 34 is fixedly installed on the side of the connecting frame 32 away from the linear motor 31, and the protection shield 34 is stored inside the side bin 15. At the same time, both the bottom of the protection shield 34 and the side close to the pole column component 2 are in an open state. The linear motor 31 drives the connecting frame 32 to drive the protection shield 34 to move towards the pole column component 2. The protection shield 34 passes through the inlet / outlet 14 and moves out from the inside of the side bin 15, and the pole column component 2 is blocked inside the protection shield 34, playing a role in multi-sided shielding protection for the pole column component 2. A plug plate is magnetically adsorbed at the open end of the protection shield 34 close to the pole column component 2. Magnetic blocks are inlaid on the opposite surfaces of the plug plate and the protection shield 34. When the protection shield 34 blocks the pole column component 2, the plug plate is magnetically attached to the open end of the protection shield 34. At this time, the pole column component 2 is completely sealed, improving the protection effect on the pole column component 2, facilitating the avoidance of damage to the pole column component 2 due to external force collision, and increasing the service life.

[0032] The protection component 3 further includes a partition plate 33 fixed inside the vertical bin 12, and the partition plate 33 divides the inside of the vertical bin 12 into a sealed cavity and an open cavity. The linear motor 31 is located inside the open cavity, and at the same time, the open cavity is connected to the inside of the side bin 15.

[0033] The pole column component 2 includes an outer sheath 21 inserted and installed on the top of the battery cover 1. An insulating sleeve 22 is installed in the inner hole of the outer sheath 21. A conductive column 23 protruding outward is installed in the inner hole of the insulating sleeve 22. A threaded hole 24 coaxial with the conductive column 23 is opened at the top of the conductive column 23.

[0034] During use, when the battery cover 1 is in a stored state, the linear motor 31 drives the connecting frame 32 to drive the protection shield 34 to move towards the pole column component 2. The protection shield 34 passes through the inlet / outlet 14 and moves out from the inside of the side bin 15, and the pole column component 2 is blocked inside the protection shield 34, playing a role in multi-sided shielding protection for the pole column component 2;

[0035] After the protection shield 34 blocks the pole column component 2, the plug plate is magnetically attached to the open end of the protection shield 34. At this time, the pole column component 2 is completely sealed, improving the protection effect on the pole column component 2, facilitating the avoidance of damage to the pole column component 2 due to external force collision, and increasing the service life;

[0036] When the protection shield 34 does not need to block the pole column component 2, the linear motor 31 moves the protection shield 34 out of the inside of the side bin 15 for storage, avoiding the protection shield 34 from getting in the way.

[0037] Embodiment 2

[0038] Refer to Figures 1-4, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is as follows:

[0040] There are three installation methods for the pole assembly 2. The first is to connect the wire to the conductive post 23 through the threaded hole 24 for power supply. The second is to fix the wire at the circular perforation 255 on the vertical conductive plate 251 through the cooperation of bolts and nuts for power supply. The third is to fix the wire at the fixed through hole 254 on the horizontal conductive plate 253 through the cooperation of bolts and nuts for power supply. By adding the supplementary pole 25 to the conductive post 23, the pole assembly 2 can have three connection methods, which can be selected according to the actual situation and are suitable for different installation environments.

[0041] The supplementary pole 25 includes a vertical conductive plate 251. An arc-shaped conductive plate 252 is integrally formed at the bottom edge of the vertical conductive plate 251. An arc-shaped groove is provided on the side of the arc-shaped conductive plate 252 close to the conductive post 23. A circular perforation 255 is opened at the center of one side of the vertical conductive plate 251.

[0042] A horizontal conductive plate 253 is integrally formed at the top edge of the vertical conductive plate 251. A fixed through hole 254 is opened at the top of the horizontal conductive plate 253.

[0043] The supplementary pole 25 further includes two arc-shaped side blocks 2510 welded on both sides of the peripheral surface of the conductive post 23. An internal threaded cylinder 259 is welded on the top of the arc-shaped side block 2510. Fixed convex strips 258 are welded at both ends of the arc-shaped conductive plate 252 close to the conductive post 23. A horizontal through hole 257 for the internal threaded cylinder 259 to pass through is opened at the top of the fixed convex strip 258. A fixing bolt 256 threadedly connected with the internal threaded cylinder 259 is arranged inside the horizontal through hole 257.

[0044] The process of installing the supplementary pole 25 on the conductive post 23 is as follows:

[0045] Insert the two internal threaded cylinders 259 into the internal of the horizontal through hole 257 correspondingly, then pass the fixing bolt 256 through the horizontal through hole 257 and threadedly connect it with the internal threaded cylinder 259, and press the fixing bolt 256 on the top of the fixed convex strip 258, so as to realize the threaded connection of the fixing bolt 256 and the internal threaded cylinder 259, and detachably install the supplementary pole 25 on the conductive post 23. It can be installed and disassembled according to requirements. At the same time, adding the supplementary pole 25 to the conductive post 23 will not affect the direct wiring of the conductive post 23.

[0046] During use, there are three installation methods for the terminal post assembly 2. The first is to connect the wire to the conductive post 23 through the threaded hole 24 for power supply;

[0047] The second is to fix the wire at the circular perforation 255 on the vertical conductive plate 251 through the cooperation of a bolt and a nut for power supply;

[0048] The third is to fix the wire at the fixed through-channel 254 on the horizontal conductive plate 253 through the cooperation of a bolt and a nut for power supply.

[0049] The remaining structures are the same as those in Embodiment 1.
