[0037] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0038] Combination Figures 1 to 5 A battery box cover with a handle comprises: a cover body 1 having a boss 11 thereon, the cover body 1 and the boss 11 are integrally formed, the boss 11 has an avoidance groove 12 and an avoidance portion; a handle 2, which is hinged on the boss 11, and the handle 2 is movably placed in the avoidance groove 12; a lead sleeve 3, which is installed on the cover body 1 and located in the avoidance portion, and the upper end surface of the lead sleeve 3 is not higher than the upper end surface of the boss 11; when the handle 2 is placed in the avoidance groove 12, the handle 2 is not higher than the upper end surface of the boss 11.

[0039] When the cover body 1 is injection molded, the lead sleeve 3 is placed in and formed integrally with the cover body 1. The upper end of the lead sleeve 3 will protrude from the upper end surface of the cover body 1, but the lead sleeve 3 is located in the avoidance portion, and the upper end surface of the lead sleeve 3 does not protrude from the upper end surface of the boss 11. At this time, the upper end of the lead sleeve 3 will be protected by the boss 11, reducing the loosening of the connection between the lead sleeve 3 and the cover body 1 due to bumps and the like. At the same time, the boss 11 makes the overall upper end surface of the battery box cover relatively flat, which is convenient for stacking and storage of batteries or battery box covers.

[0040] The number of handles 2 designed in this scheme is two, and the two ends of the handles 2 are hinged on the two sides of the boss 11 through a pin shaft. The middle part of the handle 2 rotates on the boss 11 with the pin shaft as the center of the circle, and the middle part of the handle 2 can be placed in the avoidance groove 12. At the same time, when the middle part of the handle 2 is placed in the avoidance groove 12, the handle 2 is not higher than the upper end surface of the boss 11, so that the overall upper end surface of the battery box cover is relatively flat. In order to further make the upper end surface of the battery box cover flat, the bottom of the avoidance groove 12 can also be made to bulge upward and abut against the side end of the middle part of the handle 2, so that the other side end of the middle part of the handle 2 is in the same plane as the upper end surface of the boss 11.

[0041] like Figure 3 As shown, a limiting protrusion 121 is provided on the side wall of the avoidance groove 12. When the handle 2 is placed in the avoidance groove 12, the limiting protrusion 121 abuts against the inner side wall in the middle of the handle 2 to limit the rotation of the handle 2. When the handle 2 needs to be used, an external force is used to separate the handle 2 from the limiting protrusion 121.
