[0002] At present, the walking environment of legged robots is complex. When facing a rough walking road, the parts inside the body will vibrate greatly, so they need to be reliably fixed. However, the battery pack inside the body needs to be frequently unloaded for charging, and it also needs to be easy to disassemble. Therefore, the battery pack inside the body needs to have a structure that is both reliably fixed and easy to disassemble.

[0003] In the prior art, Chinese patent CN209665367U discloses a battery pack, including a battery pack panel and a slider, the slider including a tongue, cavities are provided on both sides of the battery pack panel, the slider can slide in the cavity, and an elastic element is provided between the slider and the battery pack panel; when the elastic element applies elastic force to the slider and makes it abut against one side of the cavity, the tongue extends to the outside of the battery pack panel; when external force overcomes the elastic force provided by the elastic element and makes the slider abut against the other side of the cavity, the tongue is completely retracted into the battery pack panel. By setting the slider structure, the battery pack can be reliably fixed in the robot body and can be easily taken out.

[0004] However, the battery pack in this patent has the problem of complex structure and large space occupied. Utility Model Content

[0005] In view of this, the utility model provides a battery pack with a simple and compact structure and small occupied space.

The limiting structures such as the limiting groove in the device shell limit the locking end to achieve the installation of the battery pack. By using external force to act on the locking end, the elastic connector is stretched, causing the locking end to shrink into the battery pack, and the restriction of the battery pack in the device shell, such as the card slot in the body of a foot-type robot, is released, and the battery pack is quickly taken out. In addition, the elastic connector, the locking part and the fixing part are arranged in parallel in the installation shell, which can greatly reduce the size of the installation shell. Therefore, according to the battery pack of the utility model, the structure is simple and compact, and occupies little space.

[0011] By arranging locking parts on both sides of the mounting shell, the stability and reliability of the battery pack disassembly process can be greatly improved, and the limiting parts arranged between the locking parts can limit the two groups of locking parts at the same time, thereby further making the internal structure of the battery pack simple and compact.

[0012] In one embodiment, the limiting portion is in a step shape, and the locking portion is provided with a limiting step abutting against the limiting portion.

[0013] The locking portion is limited by the step structures cooperating with each other, which can further make the structure simple and compact and occupy a small space.

[0014] In one embodiment, the fixing portion is detachably connected to the limiting portion.

[0015] By further fixing the fixing portion to the limiting portion, the stability and reliability of the structure of the battery pack can be further improved.

[0021] Specifically, by providing a plurality of sets of sliding parts and sliding structures that cooperate with each other, it is possible to ensure to a great extent that the sliding process of the locking part is stable and reliable.

[0022] In one embodiment, the fixing portion is a long strip structure, a connecting portion is provided on the fixing portion, and a mounting portion is provided at a position on the bottom of the mounting shell corresponding to the connecting portion.

[0023] Specifically, a mounting hole is provided on the connecting portion, so as to stably and reliably fix the fixing portion in the mounting housing, thereby ensuring that the sliding process of the locking portion is stable and reliable.

[0024] In one embodiment, a through groove is provided on the outer side of the mounting shell at a position corresponding to the locking end, and an operating channel communicating with the inside and outside of the mounting shell is provided at a position on the mounting shell corresponding to the locking portion.

[0025] By setting the through groove, it is convenient to switch the locking end between inside and outside the installation shell, and the setting of the operating channel makes it easy to apply external force to the locking part through the operating channel during the installation and disassembly of the battery pack, thereby realizing the installation and disassembly of the battery pack extremely conveniently.
