[0020] Figure 1-2In the utility model, the battery terminal protection cover (hereinafter referred to as the protection cover) of the utility model prevents external foreign matter, impact, etc. The protection cover includes a cover body 4, which includes a panel 401 and a protection retaining wall 2 standing on the outer side of the panel 401. The panel 401 includes a positioning edge for contacting the battery cover and a protection edge opposite to the positioning edge. Two positioning columns 1 are erected on the inner surface of the panel 401 near the positioning edge. A positioning side plate 101 is provided on the root side of the positioning column 1. A protection retaining wall 2 is provided at the protection edge of the panel 401; the spacing between the two ends of the protection retaining wall 2 and the positioning edge forms a positioning stop 201. The protection retaining wall 2 is a step-shaped structure, including a high retaining wall 202 corresponding to the long side of the battery cover, and a low retaining wall 203 connected to the inner end of the high retaining wall 202 and corresponding to the short side of the battery cover.

[0021] A protective retaining wall 2 is designed on the side of the battery terminal protection cover close to the outside of the battery. The protective retaining wall 2 is a step-shaped structure so that one side of the battery terminal protection cover is designed to be hollow. The part close to the middle of the battery is less likely to be affected by the outside world. At the same time, the hollow design here is convenient for manual grabbing during battery installation and for removing the protective cover. Two positioning columns 1 are designed on the terminal protection cover. The spacing and structure between the positioning columns are consistent with the positioning holes on the battery, which are used to fix the protective cover. A protective retaining wall 2 is designed on the side of the battery terminal protection cover close to the outside of the battery. The color of the battery terminal protection cover is designed to be red for the positive pole and black for the negative pole, which is used for positive and negative pole identification.

[0022] Figure 3 , 4 In the figure, the battery includes a battery cover and a terminal 7. The terminal 7 is covered with a battery terminal protection cover. The battery cover includes a large cover 6 and a small cover 5. The large cover 6 has a positioning hole 8 for installing a fuse box. The positioning hole 8 includes a positioning hole that matches with a positioning column 1. The large cover 6 outside the positioning hole has a positioning notch 801 that matches with a positioning side plate 101. The depth of the positioning hole is 20 mm, the depth of the positioning notch 801 is 5 mm, and the positioning column is 15 mm.

[0023] By matching the positioning column with the positioning hole on the battery (the positioning hole is not designed specifically for the protective cover. When the battery is installed on the vehicle, a fuse box needs to be installed on the battery. The positioning hole here is to facilitate the installation of the fuse box. The European standard structure stipulates the design specifications of the positioning hole of the battery), the protective cover can be firmly installed above the battery terminal to prevent the terminal from being affected by external collisions and foreign objects. Before installing the battery, grab the low retaining wall 203 on the side of the protective cover to smoothly remove the protective cover.

[0024] The boss 601 between the positive and negative terminals is a part of the structure of the large cover 6. The boss 601 is slightly higher than the terminal height, which can prevent the positive and negative terminals from short-circuiting when metal is placed above the battery.
