[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 4The present invention provides a battery pack for an external rangefinder, including a housing assembly 10 and a battery assembly 20. The housing assembly 10 includes a shell 11 and a back cover 12. The back cover 12 is connected to the rear end of the shell 11, for example, by snapping or screwing. The shell 11 is used to be installed on the external rangefinder. The battery assembly 20 includes a battery cell 21, a discharge interface 22, a charging interface 23, and a circuit board 24. The battery cell 21 can be a rechargeable lithium-ion battery cell 21. The discharge interface 22 can be a Type-C male interface, and the charging interface 23 can be a Type-C female interface. The circuit board 24 includes a PCB board and other auxiliary electronic components. The battery cell 21, the discharge interface 22, and the charging interface 23 are connected to the circuit board 24. The battery cell 21 is arranged in the shell 11, the circuit board 24 is connected to the interior of the shell 11, and the charging interface 23 is exposed on the shell 11. During assembly, the housing 11 can be snapped onto the external rangefinder so that the discharge port 22 is connected to the external rangefinder's power port, which can be a Type-C port. By connecting the battery pack to the external rangefinder and docking the discharge port 22 with the power port on the external rangefinder, no cables are required. Furthermore, the structure is compact and the installation is stable, effectively improving the user experience of the external rangefinder.

[0031] In some embodiments, as Figure 2 As shown, a support plate 13 is provided inside the rear end of the housing 11. The support plate 13 is provided with a through hole 131. A channel is provided between the top of the support plate 13 and the inner top of the housing 11. During installation, the circuit board 24 is fixed to the rear end surface of the support plate 13 via fasteners 132, such as screws. The discharge interface 22 extends from the front end surface of the support plate 13 through the through hole 131. The battery cell 21 extends into the interior of the housing 11 through the channel. A chamber for accommodating the battery cell 21 can be provided inside the housing 11, with the rear end of the battery cell 21 positioned above the support plate 13. After the battery cell 21 and the circuit board 24 are installed in the housing 11, the back cover 12 is installed on the rear end of the housing 11 to seal the housing 11.

[0032] In some embodiments, as Figure 1 and Figure 2As shown, the bottom of the housing 11 is provided with a sloped surface 15, which has a clearance hole for the power interface of the external rangefinder. During installation, the housing 11 can be pushed toward the external rangefinder to mate the power interface with the discharge interface 22. The preload force of the two interfaces and the friction between the housing 11 and the external rangefinder ensure the stability of the battery pack when installed on the external rangefinder. Specifically, the bottom structure of the housing 11 is adapted to the outer shape of the battery pack mounting structure of the external rangefinder, and can be specifically designed to imitate the shape. For example, the battery pack mounting structure is a guide rail structure, and the bottom structure of the housing 11 is provided with a slide groove structure that cooperates with the guide rail structure and is clamped on both sides of the guide rail. For example, the bottom of the housing 11 is provided with a front plane 14 and a rear plane 16. The front plane 14, the inclined plane 15 and the rear plane 16 are distributed in sequence from front to back, and the front plane 14 is higher than the rear plane 16. During assembly, the housing 11 is placed on top of the external rangefinder with the front plane 14 contacting the top of the external rangefinder, and then the housing 11 is pushed forward until the power interface at the rear of the external rangefinder and the discharge interface 22 of the battery pack are docked. At this time, the two sides of the housing 11 adjacent to the inclined plane 15 can be clamped on both sides of the external rangefinder.

[0033] In some embodiments, the inner circumference of the rear end of the housing 11 is connected to the front end of the rear cover 12 via a buckle 17, for example Figure 2 As shown, the rear end of the housing 11 is a rectangular frame structure, the inner circumference of which is provided with a snap-fitting protrusion. The back cover 12 is also a rectangular plate structure. The front end of the back cover 12 is provided with a snap-fitting block extending toward the front end. The snap-fitting block is provided with a snap-fitting groove. When the front end of the back cover 12 contacts the rear end of the housing 11, the snap-fitting groove on the snap-fitting block can snap-fit with the snap-fitting protrusion, thereby achieving the snap-fitting of the back cover 12 and the housing 11. Multiple snap-fitting positions can be provided between the housing 11 and the back cover 12 to improve the snap-fitting stability between the two.

[0034] In some embodiments, the battery assembly 20 further includes a lamp bead 26, which is connected to the rear end surface of the circuit board 24. The lamp bead 26 can be connected to the circuit board 24 by a patch method. The number of the lamp bead 26 is multiple, for example Figure 4 As shown, four lamp beads 26 can be connected to the circuit board 24. The lamp beads 26 can be LED lamp beads 26. The back cover 12 is provided with receiving holes 123 for accommodating the lamp beads 26. The number of receiving holes 123 is the same as the number of lamp beads 26. The inner side of the back cover 12 is connected to a light guide 124. The light guide 124 is used to project light emitted by the lamp beads 26 to the outside of the back cover 12. The number of light guides 124 is the same as the number of lamp beads 26. The lamp beads 26 can display the charging and discharging status. In addition, the number of lit lamp beads 26 can also display the remaining power.

[0035] In some embodiments, the battery assembly 20 also includes a switch 25, which is connected to the rear end surface of the circuit board 24. The switch 25 can be optionally a touch switch 25, and is preferably connected to the circuit board 24 in a patch manner. The back cover 12 is provided with a mounting hole 121 for accommodating the switch 25. The back cover 12 is also provided with a button 122, which is sealed and connected to the rear end of the mounting hole 121. The button 122 is used to trigger the switch 25 when pressed. The discharge and power-off functions of the charging pack can be realized through the switch 25, so that the switch 25 can be turned on when in use and turned off when not in use, thereby avoiding waste of electricity and ensuring the battery life of the battery pack.

[0036] In some embodiments, an anti-slip layer 18 is provided on both sides of the shell 11. The anti-slip layer 18 can be a concave-convex structure provided on both sides of the shell 11, such as a knurled layer, or rubber pads can be provided on both sides of the shell 11. The anti-slip layer 18 can facilitate the user to hold the shell 11 to disassemble and assemble the battery pack.

[0037] In some embodiments, a protective cover is detachably connected to the side of the housing 11, and the protective cover is located at the charging port 23. When charging is not required, the protective cover can be buckled at the charging port 23 to provide waterproof and dustproof effects. When charging is required, the protective cover can be opened from the charging port 23.

[0038] The present invention also provides a rangefinder including any of the above battery packs for external rangefinders. For the beneficial effects of the rangefinder, reference may be made to the above battery packs for external rangefinders, which will not be described in detail here.
