[0041] like Figures 1 to 4 As shown, this embodiment provides a battery pack release device 10, which includes a battery compartment 100, a support assembly 400, a transmission assembly 500 and a sliding assembly 600. The battery compartment 100 is used to store the battery pack 200. The battery pack 200 is provided with a recessed card slot 210, and the bottom of the battery pack 200 is provided with a first elastic member 300; the support assembly 400 is provided on one side of the battery pack 200, and the support assembly 400 is fixedly connected to the battery compartment 100; the transmission assembly 500 is slidably provided on the support assembly 400 along the Z direction; the sliding assembly 600 includes a second The elastic member 610 and the latch member 620 connected to one end of the second elastic member 610, the other end of the second elastic member 610 is fixed on the battery compartment 100, the latch member 620 is slidably arranged on the support assembly 400 along the X direction, and the battery pack 200 is pressed along the Z direction. The second elastic member 610 can push the latch member 620 to move along the X direction so that the latch portion 621 of the latch member 620 is inserted into the slot 210, and the transmission assembly 500 is pressed. The transmission assembly 500 can push the latch member 620 to move in the direction of squeezing the second elastic member 610 so that the latch portion 621 is disengaged from the slot 210.

[0042] The battery pack release device 10 provided in this embodiment is provided with a transmission assembly 500 and a sliding assembly 600. After the battery pack 200 is placed in the battery compartment 100, the battery pack 200 is pressed. When the locking slot 210 of the battery pack 200 moves to a position corresponding to the locking portion 621 of the locking member 620, the second elastic member 610 pushes the locking member 620 to move along the X direction so that the locking portion 621 of the locking member 620 is inserted ( Figure 2 The arrow at A in the middle indicates the movement direction of the fastener 620) in the card slot 210, completing the fixed installation of the battery pack 200; when the battery pack 200 needs to be removed, when the transmission assembly 500 is pressed, the transmission assembly 500 moves along the Z direction. During the movement, the transmission assembly 500 pushes the fastener 620 to move in the direction of squeezing the second elastic member 610, so that the fastener portion 621 of the fastener 620 is disengaged from the card slot 210 ( Figure 2 The arrow at B in the figure indicates the movement direction of the latch 620), thereby completing the release of the battery pack 200, effectively improving the convenience of disassembly and assembly of the battery pack 200, and further improving the work efficiency during disassembly and assembly.

[0043] In this embodiment, the support assembly 400 includes a first support member 410 and a second support member 420. The transmission assembly 500 is slidably disposed through the first support member 410, and the latch 620 is slidably disposed on the second support member 420. When the transmission assembly 500 is pressed, as it slides along the first support member 410, its end pushes the latch 620 slidably disposed on the second support member 420, causing the latch 620 to squeeze the second elastic member 610, compressing the second elastic member 610. Simultaneously, the latch portion 621 gradually disengages from the latch slot 210, completing the release of the battery pack 200 and improving the release efficiency of the battery pack 200.

[0044] Optionally, the transmission assembly 500 includes a transmission member 510 and a third elastic member 520. The transmission member 510 slides along the Z-direction and penetrates the first support member 410. One end of the third elastic member 520 abuts against the transmission member 510, and the other end of the third elastic member 520 abuts against the first support member 410. By providing the third elastic member 520, the transmission member 510 is compressed when pushing the latch 620 to squeeze the second elastic member 610. After the latch portion 621 disengages from the latch slot 210, the battery pack 200 is released, and the third elastic member 520 pushes the transmission member 510 to rebound to its initial position, allowing it to repeat its action and improving its usability.

[0045] Furthermore, a first cylindrical boss 4111 is provided on the first support member 410, and a second cylindrical boss 511 is provided on the transmission member 510. One end of the third elastic member 520 is sleeved on the first cylindrical boss 4111, and the other end of the third elastic member 520 is sleeved on the second cylindrical boss 511, providing guidance and position limiting for the third elastic member 520, thereby improving the operational stability and reliability of the third elastic member 520. In this embodiment, the first support member 410 has a first platform 411 perpendicular to the Z-direction. The transmission member 510 slides along the Z-direction through the first platform 411, and the first cylindrical boss 4111 protrudes from the first platform 411 to provide sufficient support for the third elastic member 520.

[0046] Preferably, if Figure 5 and Figure 6 As shown, the transmission member 510 has a limit platform 513, and the second support member 420 is provided with a limit buckle 421 that cooperates with the limit platform 513. After the transmission member 510 rebounds a certain distance, the limit platform 513 on the transmission member 510 is stuck on the limit buckle 421. The limit buckle 421 can prevent the transmission member 510 from detaching from the support assembly 400 due to excessive rebound distance, thereby improving the reliability of use.

[0047] In this embodiment, if Figure 5 、 Figure 7 and Figure 8As shown, the transmission member 510 has a first inclined surface 512, and the latch 620 has a second inclined surface 622 that cooperates with the first inclined surface 512. When the transmission member 510 moves in the Z direction, the first inclined surface 512 of the transmission member 510 contacts the second inclined surface 622 of the latch 620. During the movement of the transmission member 510 in the Z direction, a uniform thrust is applied to the second inclined surface 622 in the X direction, pushing the latch 620 to squeeze the second elastic member 610, and at the same time, disengaging the latch portion 621 from the latch slot 210, thereby releasing the battery pack 200.

[0048] Specifically, the latch 620 is configured as a convex-shaped structure, with a latch portion 621 disposed on one side of the convex-shaped structure. The convex-shaped structure is provided with a square through-hole, and a portion of the hole wall of the square through-hole away from the latch portion 621 forms a second inclined surface 622. When the transmission member 510 moves in the Z-direction, the transmission member 510 is inserted into the square through-hole, and its first inclined surface 512 abuts against the second inclined surface 622 of the latch 620, along which the transmission member 510 moves. The square through-hole effectively prevents the transmission member 510 from shaking during movement.

[0049] Optionally, a limiting groove 623 is provided on the other side of the locking member 620, and the limiting groove 623 is used to limit the end of the second elastic member 610 to prevent the end of the second elastic member 610 from moving and deviating during the squeezing process.

[0050] See also Figure 1 、 Figure 2 and Figure 9 The battery pack release device 10 further includes an operating member 700, which is disposed at an end of the transmission assembly 500 away from the sliding assembly 600 and slides through the first support member 410 of the support assembly 400. This arrangement allows the operating member 700 to move the transmission member 510 simply by pressing the operating member 700. This increases the height of the operating member and improves operational convenience.

[0051] Optionally, the operating member 700 is configured as a cylindrical ring structure and includes a sliding portion 710 and a pressing portion 720. The sliding portion 710 slides through the first support member 410 of the support assembly 400, and the pressing portion 720 is located at the end of the sliding portion 710 away from the transmission assembly 500. The sliding portion 710 slides on the first support member 410, and the first support member 410 can limit the sliding portion 710, thereby improving the movement stability of the operating member 700. Specifically, in this embodiment, the first support member 410 has a second platform perpendicular to the Z direction, which is arranged parallel to the first platform 411. The sliding portion 710 slides through the second platform. When the operating member 700 is pressed, the transmission member 510 moves to its lowest end, and the pressing portion 720 abuts against the second platform, providing support for the pressing portion 720.

[0052] Furthermore, the sliding column portion 710 includes a first annular body 711 and a second annular body 712 that are spaced apart from each other. The height of the first annular body 711 is greater than that of the second annular body 712. The end of the first annular body 711 away from the pressing portion 720 can abut against the transmission member 510. By providing the first annular body 711 and the second annular body 712, both the first annular body 711 and the second annular body 712 are slidably provided through the first support member 410, thereby improving sliding stability.

[0053] In this embodiment, the buckle portion 621 and the slot 210 are both configured as triangular structures. When the buckle portion 621 is inserted into the slot 210 , the buckle portion 621 enters along the edge of the slot 210 , thereby improving the smoothness of the insertion of the buckle portion 621 into the slot 210 .

[0054] Optionally, a handle 220 is provided on the battery pack 200 to facilitate taking the battery pack 200 .

[0055] It is worth noting that in practical applications, Figure 10 and Figure 11 As shown, one or more battery packs 200 are typically provided. For example, when there are two battery packs 200, the two battery packs 200 can be symmetrically arranged in the battery compartment 100, and the opposing inner sides of the two battery packs 200 are each provided with a latching slot 210. Two mutually symmetrical and interconnected support assemblies 400, two mutually symmetrically arranged operating members 700, two symmetrically arranged transmission assemblies 500, and two symmetrically arranged sliding assemblies 600 are provided between the two battery packs 200, effectively reducing the space occupied by the support assemblies 400, the transmission assemblies 500, and the sliding assemblies 600.

[0056] This embodiment also provides a sweeping robot, which includes a sweeping robot body 20 and a battery pack release device 10. The battery compartment 100 is arranged on the sweeping robot body 20. A circular groove is provided on the sweeping robot body 20. The end of the first elastic member 300 away from the battery pack 200 abuts against the circular groove.

[0057] The sweeping robot provided in this embodiment can quickly complete the disassembly and assembly of the battery pack 200 , thereby improving the convenience of disassembly and assembly of the battery pack 200 .

[0058] Optionally, a stopper protrusion 230 is provided on the bottom of the battery pack 200, which is positioned outside the first elastic member 300. When the battery pack 200 is pressed, the stopper protrusion 230 penetrates the wall of the battery compartment 100 and inserts into the circular groove. The stopper protrusion 230 not only prevents the first elastic member 300 from shifting, but also improves the relative stability between the battery pack 200 and the robot body 20 during the compression of the first elastic member 300.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
