[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 7 The utility model embodiment includes: a battery anti-detachment structure, which includes a frame shell 1, a battery compartment 2 is arranged in the frame shell 1, the bottom of the battery compartment 2 is open, a battery 3 is arranged in the battery compartment 2, a battery front connecting plate 4 is arranged at one end of the battery compartment 2, a groove 5 extending up and down is arranged on the battery front connecting plate 4, a battery end cover 6 is arranged at one end of the battery 3, the battery end cover 6 is close to the battery front connecting plate 4, a blind hole 7 is transversely arranged on the battery end cover 6, a spring 8 is arranged in the blind hole 7, a steel ball 9 is arranged at the outer end of the spring 8, and a part of the steel ball 9 is located outside the blind hole 7 and located in the groove 5.

[0022] Preferably, the groove walls at the upper and lower ends of the groove 5 are arc surfaces.

[0023] Preferably, a battery rear connecting plate 10 is provided at the other end of the battery compartment 2, a battery tail cover 11 is provided at the other end of the battery 3, a connecting groove 12 is provided on the battery tail cover 11, a connecting protrusion 13 is provided on the battery rear connecting plate 10, and the connecting protrusion 13 is movably provided in the connecting groove 12.

[0024] Preferably, a portion of the steel ball 9 can slide in the groove 5 .

[0025] Preferably, a laterally protruding bump 14 is provided on the battery end cover 6 , the blind hole 7 is located inside the bump 12 , and the opening of the blind hole 7 is close to the groove 5 .

[0026] Preferably, the frame housing 1 is provided with a locking mechanism 15 for fixing the battery 3 on the frame housing 1, and when the locking mechanism 15 is opened, the steel ball 9 slides from the upper end of the groove 5 to the lower end of the groove 5. The locking mechanism 15 can be a product that has been maturely applied in the prior art.

[0027] When the battery anti-dropping structure of the utility model is in use, the spring 8 presses against the steel ball 9, and the steel ball 9 is always pressed in the groove 5 on the front connecting plate 4 of the battery. At this time, the locking mechanism 15 locks and fixes the battery 3 on the frame shell 1; when the locking mechanism 15 is opened, the battery 3 moves downward due to its own weight, and when it moves to the lower end of the groove 5, it is blocked by the lower end groove wall of the groove 5. Because the spring 8 presses against the steel ball 9 and is stuck at the lower end of the groove 5 and does not move, the battery 3 will also be stuck, so that the battery 3 will not fall off, thereby achieving the purpose of anti-dropping; by manually applying external force to the battery 3 and pulling the battery downward with force, the spring 8 will retract, the steel ball 9 will be separated from the groove 5, and the battery 3 will be taken out, thereby overcoming the problem that the battery 3 will fall directly when the locking mechanism 15 is opened, thereby increasing the safety of taking out the battery, and the entire battery anti-dropping structure has a simple structure, occupies a small space, is easy to operate, and has a low cost.
