[0026] The utility model provides a shell with a waterproof battery cover.

[0027] like Figure 1 and Figure 4As shown, the shell with a waterproof battery cover provided by the embodiment of the utility model includes a base 10 and a battery cover 20 that can be covered on the base 10, a first waterproof structure 30 is provided between the base 10 and the battery cover 20, the battery cover 20 includes a bottom cover 21 and a top cover 22 that are detachably connected, a battery compartment 23 for installing batteries is provided in the base 10, and a second waterproof structure 40 is provided between the bottom cover 21 and the top cover 22.

[0028] In this embodiment, by providing a first waterproof structure 30 between the base 10 and the battery cover 20 and providing a second waterproof structure 40 between the bottom cover 21 and the top cover 22 of the battery cover 20, the waterproof performance of the battery cover 20 can be significantly improved to prevent external water vapor from entering through the joints of the components.

[0029] Specifically, please refer to Figure 2 and Figure 3 The top cover 22 includes a top plate 221 and an annular baffle 222 extending along the outer edge of the top plate 221 toward the bottom cover 21. The first waterproof structure 30 is disposed between the annular baffle 222 and the base 10. The first waterproof structure 30 is a first sealing ring. A clamping groove 223 clamped on the first sealing ring is disposed at the bottom of the annular baffle 222. In this embodiment, the first sealing ring is disposed on the bottom cover 21. When the annular baffle 222 of the top cover 22 is pressed downward, the first sealing ring will be clamped in the clamping groove 223 to improve the stability of the first sealing ring, and the sealing ring can be used to block the joint between the top cover 22 and the bottom cover 21 to prevent external water vapor from entering.

[0030] At the same time, in order to improve the connection stability between the top cover 22 and the bottom cover 21, in one embodiment, along the circumference of the bottom cover 21, a plurality of notches 211 are provided on the top of the bottom cover 21, and a plurality of first locking parts 224 that can correspond to the notches 211 are provided on the annular bottom plate, and when the annular bottom plate moves in the direction toward the bottom cover 21, the first locking parts 224 can be pressed into the notches 211 and the clamping groove 223 is clamped on the first sealing ring. That is to say, when the annular baffle 222 of the top cover 22 is pressed downward, the first locking part 224 will first move downward with the guide slope provided on the notch 211, and when it continues to move downward, the first locking part 224 will be clamped into the notch 211, thereby completing the installation between the top cover 22 and the bottom cover 21. And when the lock hook part and the notch 211 are clamped, the clamping groove will just be clamped on the first sealing ring.

[0031] In order to facilitate the correct alignment of the notch 211 and the lock portion when the top cover 22 and the bottom cover 21 are connected, in one embodiment, a positioning hole 212 is provided on the top of the bottom cover 21, and a positioning protrusion 225 is provided on the side of the top cover 22 facing the bottom cover 21, and the positioning protrusion 225 can be inserted into the positioning hole 212. In other words, when the positioning protrusion 225 is aligned with the positioning hole 212 and can be correctly inserted into the positioning hole 212, the lock portion can cooperate with the notch 211.

[0032] In the above embodiment, along the axial direction of the bottom cover 21 , the outer peripheral surface of the bottom cover 21 is in a concave curved shape to reduce material consumption and lower production costs.

[0033] Also, please refer to Figure 2 , the bottom cover 21 is provided with a plurality of second locking parts 213 inside, and the plurality of second locking hook parts define an installation area for installing a PCB board. In this embodiment, the number of the second locking parts 213 is multiple and they form a rectangular installation area. The principle of installing the PCB board is the same as the principle of cooperation between the locking part and the notch part 211, and both adopt continuous pressing to make the second locking part 213 limit the PCB board, so that the PCB board cannot be separated from the pressing direction, so as to complete the installation.

[0034] In the above embodiment, the bottom cover 21 is provided with a mounting groove 214, and a display screen can be installed at the mounting groove 214 to indicate data of the device to the user through the display screen. It can be understood that in this application, the connection between the battery, the PCB board, and the display screen can be connected by conventional technology, which will not be repeated here.

[0035] Also, please refer to Figure 4 The top of the base 10 is provided with a step portion 12, the bottom of the bottom cover 21 is provided with a blocking plate 215, a cavity 13 is defined between the blocking plate 215 and the step portion 12, the second waterproof structure 40 is a second sealing ring, and the second sealing ring is installed in the cavity 13. The base 10 is provided with an inserting cavity 11, the blocking plate 215 can be inserted into the inserting cavity 11 and abut against the inner wall surface of the step portion 12 to enclose the cavity 13.

[0036] In this embodiment, the second sealing ring is arranged at the step portion 12. When the bottom cover 21 is pressed into the base 10, the blocking plate 215 is inserted into the plug-in cavity 11. At this time, a cavity 13 is formed between the blocking plate 215 and the step portion 12, and the second sealing ring is located in the cavity 13. The outer peripheral wall of the second sealing ring will contact the step portion 12 and the blocking portion, thereby sealing the base 10 and the bottom cover 21, thereby improving the waterproof performance of the present application. In addition, through holes aligned with the positions of the LED lights on the PCB board are arranged on the top cover 22. The two on the left are used to transmit light to the indicator lights on the PCB board (one turns on the green light, and the other turns off the red light), and the rightmost one is the button position of the circuit board test button. It can be understood that the through hole can be sealed by setting a sealed glass cover and a sealed button to prevent water vapor from entering the interior through the through hole.

[0037] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
