The shape of the battery cover 1200 matches the shape of the opening 1110 of the outer shell 1100. After the battery 1400 is placed in the battery cavity 1120, the battery cover 1200 is assembled with the outer shell 1100 from the opening 1110 of the outer shell 1100. After the battery cover 1200 and the outer shell 1100 are assembled, the battery cavity 1120 becomes a closed chamber.

[0042] In the battery cover 1200, a lever is provided at the top of the push button 1230, and a strip hole is provided at the top of the cover body 1210. The lever of the push button 1230 is passed through the top of the cover body 1210, and the push button 1230 is driven to slide in the cover body 1210 by pushing the lever along the strip hole; the first waterproof ring 1220 is provided on the top inner wall of the cover body 1210 and along the outer edge of the strip hole, the lever passes through the first waterproof ring 1220, and the upper end surface of the push button 1230 abuts against the first waterproof ring 1220. Move the lever to the two ends of the strip hole, and slide the corresponding push knob 1230 to the locking position and the unlocking position respectively; when the push knob 1230 is in the locking position, the push knob 1230 will lock the battery cover 1200 and the outer shell 1100, and under the action of the pressing block 1240, the push knob 1230 will press the first waterproof ring 1220 against the cover body 1210 to achieve a waterproof seal; when the push knob 1230 is in the unlocking position, the battery cover 1200 and the outer shell 1100 are in an unlocked state, and the battery cover 1200 can be plugged in and out relative to the outer shell 1100.

[0043] The waterproof strip 1300 is arranged along the shape of the opening 1110 , and the waterproof strip 1300 is arranged between the connection points of the battery cover 1200 and the housing 1100 .

[0044] In this embodiment, a waterproof strip 1300 is provided between the battery cover 1200 and the housing 1100. When the battery cover 1200 and the housing 1100 are combined with each other, the waterproof strip 1300 prevents water vapor from entering the gap between the battery cover 1200 and the housing 1100. The battery cover 1200 is provided with a push knob 1230 and a pressing block 1240. When the push knob 1230 is turned to lock the battery cover 1200 and the housing 1100, a force is applied to the push knob 1230 toward the cover body 1210 by the pressing block 1240, so that the push knob 1230 pushes the first waterproof ring 1220 toward the cover body 1210. 210 is pressed tightly, so that the gap between the push knob 1230 and the cover body 1210 can also be effectively sealed by the first waterproof ring 1220, thereby preventing water vapor from entering the battery compartment 1000 through the gap between the push knob 1230 and the cover body 1210; through the special waterproof settings between the battery cover 1200 body and the battery cover 1200 and the outer shell 1100, while facilitating the opening of the battery cover 1200 to replace the battery 1400, it can also effectively improve the overall waterproof and anti-condensation performance of the battery compartment 1000, thereby preventing the electronic devices in the battery compartment 1000 from being corroded by water vapor and increasing the service life of the battery compartment 1000.

[0045] In some embodiments, the housing 1100 is provided with a step 1111 on the inner wall at the opening 1110, the step 1111 is arranged along the shape of the opening 1110, and the waterproof strip 1300 is arranged on the step 1111.

After the battery cover 1200 is combined with the housing 1100, the inner side wall of the battery cover 1200 and the steps 1111 together squeeze the waterproof strip 1300 to achieve a seal between the battery cover 1200 and the edge of the housing 1100. The step 1111 can be provided to position the waterproof strip 1300 to prevent the waterproof strip 1300 from being skewed; at the same time, the waterproof strip 1300 is provided on the surface of the step 1111 facing the top of the housing 1100, and the direction in which the waterproof strip 1300 is squeezed is the same as the direction in which the battery cover 1200 is disassembled, so as to prevent the waterproof strip 1300 from being skewed or loosened due to the disassembly of the battery cover 1200.

[0046] In some embodiments, the housing 1100 includes a shell 1130, a waterproof pad 1140 and a cover plate 1150, one side of the shell 1130 is closed, the cover plate 1150 is arranged on the other side of the shell 1130 to form the battery chamber 1120, and a waterproof pad 1140 is arranged between the cover plate 1150 and the shell 1130. Figure 3As shown, the shape of the waterproof pad 1140 matches the shape of the cover plate 1150. After the cover plate 1150 and the shell 1130 are installed, the waterproof pad 1140 is located between the edge of the cover plate 1150 and the shell 1130, forming an overall seal between the cover plate 1150 and the shell 1130 to achieve waterproofing and anti-condensation.

[0047] In some embodiments, the inner wall of the other side of the housing 1130 is provided with a housing boss 1131, the waterproof pad 1140 is provided on the housing boss 1131, and the cover plate 1150 is embedded and provided on the other side of the housing 1130 and abuts against the waterproof pad 1140. Figure 1 As shown, the housing boss 1131 is arranged along the inner wall of the other side of the housing 1130, and the waterproof pad 1140 is arranged on the surface of the housing boss 1131 facing the cover plate 1150; after the cover plate 1150 is assembled with the housing 1130, the edge of the cover surface and the surface of the housing boss 1131 form an extrusion on the waterproof pad 1140 to achieve sealing and waterproofing. By setting the housing boss 1131, the waterproof pad 1140 can be positioned, which is convenient for assembly and avoids the waterproof pad 1140 from being skewed.

[0048] In some embodiments, an elastic buckle 1212 is provided on the side where the cover body 1210 is connected to the shell 1100, and a first slot 1160 corresponding to the elastic buckle 1212 is provided on the inner wall of the shell 1100; a push-twist boss 1231 is provided on the side of the push knob 1230, and when the push knob 1230 is moved to the locking position, the push-twist boss 1231 abuts against the elastic buckle 1212 and applies a force to the elastic buckle 1212 toward the first slot 1160.

[0049] Among them, Fig. 9 and Fig.10As shown, two elastic buckles 1212 are provided on one side of the cover 1210, and one elastic buckle 1212 is provided on the other side. By providing three buckles, the connection between the battery cover 1200 and the housing 1100 can be made more stable. The inner wall of the housing 1100 opposite to the side of the cover 1210 is provided with first card slots 1160 of corresponding number and shape, and the first card slots 1160 can be engaged with the elastic buckle 1212 to achieve the locking of the cover 1210 and the housing 1100. When the push-twist 1230 is moved to the locking position, the push-twist boss 1231 abuts against the elastic buckle 1212, and at this time, the elastic buckle 1212 cannot be elastically deformed, and the elastic buckle 1212 is locked with the first card slot 1160, so that the battery cover 1200 cannot be pulled out, thereby achieving the locking of the battery cover 1200 and the housing 1100. When the push knob 1230 is moved to the unlocking position, the push knob 1231 is misaligned with the elastic buckle 1212, and the elastic buckle 1212 can be elastically deformed. When the battery cover 1200 needs to be pulled out, the elastic buckle 1212 is separated from the first slot 1160 by deformation, and the battery cover 1200 is unlocked from the housing 1100. The push knob 1231 allows the first slot 1160 to be clamped with the elastic buckle 1212, and the battery cover 1200 can be firmly fixed in this position. The battery cover 1200 cannot be removed from the housing 1100, and the battery cover 1200 compresses the waterproof rubber strip for a long time, achieving a long-term waterproof and anti-condensation effect.

[0050] In some embodiments, the inner wall of the cover 1210 facing the push button 1230 is provided with a groove 1211, and the first waterproof ring 1220 is embedded in the groove 1211. Figure 5 As shown, the overall shape of the groove 1211 matches the strip hole at the top of the cover body 1210. The groove 1211 is arranged along the edge of the strip hole at the top of the cover body 1210. The first waterproof ring 1220 is embedded in the groove 1211, which can effectively prevent the first waterproof ring 1220 from shifting due to squeezing, thereby affecting the waterproof effect.

[0051] In some embodiments, the pressing block 1240 is fixedly connected to the cover body 1210; the pressing block 1240 is provided with a convex strip 1241, and the bottom of the push knob 1230 is provided with a second card slot 1232 matching the top of the convex strip 1241. During the movement of the push knob 1230, the second card slot 1232 is offset from the top of the convex strip 1241, and the pressing block 1240 gives the push knob 1230 a force toward the cover body 1210 through the convex strip 1241.

[0052] Among them, Figure 6As shown, the pressing block 1240 is fixedly connected to the cover body 1210 by screws, and the push knob 1230 can slide between the pressing block 1240 and the cover body 1210. A convex strip 1241 capable of elastic deformation is provided in the middle of the pressing block 1240, and the tip of the convex strip 1241 faces the bottom of the push knob 1230; a second card slot 1232 matching the tip of the convex strip 1241 is provided on one side of the bottom of the push knob 1230, and the push knob 1230 can be limited by the second card slot 1232 and the tip of the convex strip 1241, so as to prevent the displacement of the push knob 1230 and cause the battery cover 1200 and the housing 1100 to be loosened. When the battery cover 1200 and the housing 1100 are combined, the push knob 1230 is not moved, and the push knob 1230 is still in the unlocking position, the tip of the convex strip 1241 of the pressing block 1240 and the second card slot 1232 are mutually engaged. When the push knob 1230 is moved to the locking position, the tip of the convex strip 1241 is staggered with the second card slot 1232, and the tip of the convex strip 1241 abuts against the bottom of the push knob 1230. Due to the interaction force, the convex strip 1241 is elastically deformed to apply pressure to the push knob 1230 toward the top of the cover body 1210, so that the push knob 1230 presses the first waterproof ring 1220, and the seal can be ensured during the process of moving the push block. When the push knob 1230 is moved to the locking position, the tip of the convex strip 1241 of the pressure block 1240 is engaged with the other second card slot 1232, so as to limit the push knob 1230 and prevent the displacement of the push knob 1230 from causing the battery cover 1200 and the housing 1100 to loosen.

[0053] By setting the second card slot 1232 of the push-button 1230 and the convex strip 1241 of the pressing block 1240, while facilitating opening the battery cover 1200 to replace the battery 1400, it can also effectively improve the overall waterproof and anti-condensation performance of the battery compartment 1000, thereby preventing the electronic components in the battery compartment 1000 from being corroded by water vapor and increasing the service life of the battery compartment 1000.

[0054] In some embodiments, a mainboard cavity 1170 is further disposed at the other end of the housing 1100, and a partition 1180 is disposed between the mainboard cavity 1170 and the battery cavity 1120.
