[0026] The present invention will be further described with reference to the following examples and accompanying drawings:

[0027] A waterproof device for a battery holder, such as Figures 1 to 9As shown, the control device 50 is arranged on the battery base 10 with the battery holder 11 and is used to protect the battery connection terminal 12 of the battery holder 11, including: a connecting mounting groove 13 and a guide groove 14 arranged on the battery base 10, a mounting sleeve 20 arranged on the mounting groove 13, an elastic body 30 arranged in the mounting groove 13 and stuck under the mounting sleeve 20 and capable of being compressed downward and rebounding, a protective cover 40 movably connected to the mounting sleeve 20, and a control device 50 in which the protective cover 40 covers the battery holder 11 when the elastic body 30 is in a free state, and when the battery 60 presses down the mounting sleeve 20 to compress the elastic body 30, the protective cover 40 is flipped up, and the protective cover 40 moves downward with the mounting sleeve 20 and is pressed into the guide groove 14. The elastic body 30 can be a spring, or a silicone elastic body or a rubber elastic body. Of course, the elastic body 30 can be other elastic bodies 30 in the prior art that can be compressed downward under force to produce elastic deformation, and cancel the force rebound to a free state.

[0028] The elastomer 30 of the waterproof device of the battery holder of the present invention is stuck under the mounting sleeve 20. When the battery 60 is not installed, the elastomer 30 is in a free state. The protective cover 40 movably connected to the mounting sleeve 20 covers the battery holder 11, which can effectively protect the battery connection terminals 12 of the battery holder 11 and prevent the battery connection terminals 12 of the battery holder 11 from being exposed to the outside, so as to avoid the battery holder 11 from contacting water in rainy and snowy weather or improper operation, thereby avoiding circuit short circuit and equipment damage. In addition, the protective cover 40 covers the battery holder 11, which can also play a good role in preventing dust and mechanical damage. When installing the battery 60, the battery 60 is installed on the mounting sleeve 20, and the battery 60 presses down the mounting sleeve 20, thereby compressing the elastomer 30. At this time, the control device 50 controls the protective cover 40 to flip up, and the flipping direction of the protective cover 40 is as follows: Figure 3 As shown in the direction A of the mounting sleeve 20, the protective cover 40 is attached to the outside of the mounting sleeve 20, and as the mounting sleeve 20 moves downward, the mounting sleeve 20 is completely pressed into the mounting groove 13, and the protective cover 40 is pressed into the guide groove 14, the battery connection terminal 12 of the battery holder 11 is exposed to the outside, and the pole ear of the battery 60 is electrically connected to the battery connection terminal 12 of the battery holder 11, thereby realizing the installation of the battery 60, and the installation operation of the battery 60 is very convenient. When the battery 60 is taken out, the force pressing down the mounting sleeve 20 disappears, and as the elastic body 30 rebounds and recovers to a free state, the mounting sleeve 20 rises, and the control device 50 controls the protective cover 40 to cover back on the battery holder 11, thereby protecting the battery holder 11. When the battery 60 is taken out, the force pressing down the mounting sleeve 20 disappears, and as the elastic body 30 rebounds and recovers to a free state, the mounting sleeve 20 rises, and the control device 50 controls the protective cover 40 to cover back on the battery holder 11, thereby protecting the battery holder 11.

[0029] As can be seen from the above, the waterproof device of the battery holder of the present invention has a simple structure, the battery 60 is very convenient to install during use, and has good waterproof and dustproof protection effects.

[0030] As an embodiment of the waterproof device of the battery holder of the present invention, Figures 1 to 6 As shown, the control device 50 includes two support arms 21 arranged on the side of the installation sleeve 20, a rotating shaft 51, and a torsion spring 52 sleeved on the rotating shaft 51. The opposite surfaces of the two support arms 21 are provided with a first axial hole 22, one end of the protective cover 40 is provided with an outwardly protruding connecting arm 41, and the connecting arm 41 is provided with a second axial hole 42. The rotating shaft 51 passes through the second axial hole 42 and both ends are sleeved in the first axial hole 22. When the torsion spring 52 is in a free state, one end 53 is pressed on the protective cover 40, and the other end 54 is pressed on the side wall of the installation sleeve 20 higher than the support arm 21.

[0031] The torsion spring 52 is sleeved on the rotating shaft 51, and the rotating shaft 51 passes through the second shaft hole 42 and the two ends are sleeved in the first shaft hole 22. Through the rotating shaft 51, the protective cover 40 and the mounting sleeve 20 are movably connected. When the torsion spring 52 is in a free state, one end 53 is pressed on the protective cover 40, and the other end 54 is pressed on the side wall of the mounting sleeve 20 that is higher than the support arm 21. That is, when the battery 60 does not press down the mounting sleeve 20 and then compress the elastic body 30, the protective cover 40 covers the battery holder 11, which can effectively protect the battery connection terminal 12 of the battery holder 11, and prevent the battery connection terminal 12 of the battery holder 11 from being exposed to the outside, so as to avoid the battery holder 11 from contacting water in rainy and snowy weather or improper operation, and avoid circuit short circuit and equipment damage caused by this. Moreover, the protective cover 40 covers the battery holder 11, which can also play a good role in preventing dust and mechanical damage.

[0032] When installing the battery 60, the battery 60 is installed on the mounting sleeve 20. The battery 60 presses down the mounting sleeve 20, thereby compressing the elastomer 30, and the elastomer 30 generates compression deformation. At this time, because the mounting sleeve 20 moves downward, the protective cover 40 movably connected to the mounting sleeve 20 is flipped upward due to the limiting top force of the battery holder 11. After the protective cover 40 is flipped up, it sticks to the outside of the mounting sleeve 20. At this time, the torsion spring 52 is compressed, and the torsion spring 52 generates compression deformation. As the mounting sleeve 20 moves downward, the mounting sleeve 20 is completely pressed into the mounting groove 13, and the protective cover 40 is pressed into the guide groove 14. The battery connection terminal 12 of the battery holder 11 is exposed to the outside, and the pole ear of the battery 60 is electrically connected to the battery connection terminal 12 of the battery holder 11, thereby realizing the installation of the battery 60, and the installation operation is very convenient.

[0033] After the battery 60 is taken out, the force pressing down the mounting sleeve 20 disappears. As the elastic body 30 rebounds and recovers to a free state, the mounting sleeve 20 rises, and the protective cover 40 movably connected to the mounting sleeve 20 also rises. When the protective cover 40 rises to a level higher than the battery holder 11, the compression force on the torsion spring 52 disappears. Under the elastic force of the torsion spring 52, the torsion spring 52 recovers to a free state. Under the action of the torsion spring 52, the protective cover 40 flips down to a horizontal state, and then covers the battery holder 11 again.

[0034] Preferably, if Figures 1 to 5 As shown, there are two connecting arms 41, two torsion springs 52, and the torsion springs 52 are arranged between adjacent support arms 21 and connecting arms 41. There are two connecting arms 41 and torsion springs 52, and there are two connection points between the protective cover 40 and the mounting sleeve 20. When the protective cover 40 is turned up or down, the action is more stable and reliable. The two torsion springs 52 act to control the protective cover 40 to be more powerful when it is turned down.

[0035] As a second embodiment of the waterproof device of the battery holder of the present invention, Figures 7 to 9 As shown, the control device 50 includes two support arms 21 arranged on the side of the mounting sleeve 20, a rotating shaft 51, and a boss 90 arranged on the side of the mounting sleeve 20 and located above the support arms 21. The opposite surfaces of the two support arms 21 are provided with a first axial hole 22, one end of the protective cover 40 is provided with an outwardly protruding connecting arm 41, and the connecting arm 41 is provided with a second axial hole 42. The rotating shaft 51 passes through the second axial hole 42 and is sleeved in the first axial hole 22 at both ends.

[0036] The rotating shaft 51 passes through the second shaft hole 42 and is sleeved in the first shaft hole 22 at both ends. The rotating shaft 51 realizes the movable connection between the protective cover 40 and the mounting sleeve 20. When the battery 60 does not press down the mounting sleeve 20 and then compress the elastic body 30, the protective cover 40 covers the battery holder 11, which can effectively protect the battery connection terminal 12 of the battery holder 11, and prevent the battery connection terminal 12 of the battery holder 11 from being exposed to the outside, so as to avoid the battery holder 11 from contacting water in rainy and snowy weather or improper operation, and avoid circuit short circuit and equipment damage caused by this. Moreover, the protective cover 40 covers the battery holder 11, which can also play a good role in preventing dust and mechanical damage.

[0037] When installing the battery 60, the battery 60 is installed on the mounting sleeve 20. The battery 60 presses down the mounting sleeve 20, thereby compressing the elastomer 30, and the elastomer 30 produces compression deformation. At this time, because the mounting sleeve 20 moves downward, the protective cover 40 movably connected to the mounting sleeve 20 is flipped upward due to the limiting top force of the battery holder 11, and the protective cover 40 is close to the boss 90 of the mounting sleeve 20. After the protective cover 40 is flipped up, it is attached to the outside of the mounting sleeve 20. As the mounting sleeve 20 moves downward, the mounting sleeve 20 is completely pressed into the mounting groove 13, and the protective cover 40 is pressed into the guide groove 14. The protective cover 40 is attached to the boss 90, and the battery connection terminal 12 of the battery holder 11 is exposed outside. The pole ear of the battery 60 is electrically connected to the battery connection terminal 12 of the battery holder 11, thereby realizing the installation of the battery 60, and the installation operation is very convenient. The protruding length of the boss 90 is sufficient so that when the protective cover 40 is close to the boss 90 of the mounting sleeve 20, that is, the protective cover 40 is tilted relative to the mounting sleeve 20 toward the battery holder 11, the guide groove 14 can accommodate the downwardly moved protective cover 40.

[0038] After the battery 60 is taken out, the force pressing down the mounting sleeve 20 disappears. As the elastic body 30 rebounds and recovers to a free state, the mounting sleeve 20 rises, and the protective cover 40 movably connected to the mounting sleeve 20 also rises; when the protective cover 40 rises to be higher than the battery holder 11, due to the action of the protruding boss 90 of the mounting sleeve 20, the upper end of the protective cover 40 tilts toward the battery holder 11, and due to the action of gravity, the protective cover 40 flips down to a horizontal state, and then covers the battery holder 11 again.

[0039] Further preferably, the boss 90 is disposed at the upper end of the side of the mounting sleeve 20. By disposing the boss 90 at the upper end of the side of the mounting sleeve 20, a larger inclination of the protective cover 40 can be obtained under the condition of the minimum protruding length of the boss 90, which helps the protective cover 40 to flip down to a horizontal state when the protective cover 40 rises to a position higher than the battery holder 11.

[0040] Preferably, if Figure 5 and Fig. 9 As shown, the lower end of the mounting sleeve 20 is provided with a slot 24, and the upper end of the elastic body 30 is stuck in the slot 24. The upper end of the elastic body 30 is stuck in the slot 24, which can ensure that when the mounting sleeve 20 presses down the elastic body 30 and the elastic body 30 rebounds to lift the mounting sleeve 20, the elastic body 30 and the mounting sleeve 20 will not shift, thereby ensuring the reliability of the action.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
