The technical solution of the embodiment of the present application can realize the simultaneous charging of multiple cleaning robots 100 with only one charging pile. In addition, the cleaning robot 100 of this embodiment adopts an electrical connection between the first electrical connection portion 130 and the second electrical connection portion 140, so that the charging pile can still supply power to the subsequent cleaning robot 100 while the existing cleaning robot 100 is being charged, thereby improving the charging efficiency. In the embodiment of the present application, any two adjacent cleaning robots 100 can be electrically connected in various ways, and can be charged by connecting end to end or tail to tail.

[0041] In some preferred embodiments, the first electrical connection portion 130 and the second electrical connection portion 140 are respectively located in different directions around the body 110 to facilitate electrical connection between the two cleaning robots 100. Those skilled in the art may also flexibly adjust the positions of the first electrical connection portion 130 and the second electrical connection portion 140 according to actual conditions, and changes in the positions of the first electrical connection portion 130 and the second electrical connection portion 140 are all within the scope of protection of the present invention.

[0042] Furthermore, the first electrical connection portion 130 and the second electrical connection portion 140 are preferably disposed at two opposite ends of the body 110 , that is, one of the first electrical connection portion 130 and the second electrical connection portion 140 is located at the head of the body 110 , and the other is located at the tail of the body 110 .

[0043] In this embodiment, the first electrical connection portion 130 is disposed near the front position relative to the forward direction of the cleaning robot 100, and the second electrical connection portion 140 is disposed near the rear position relative to the forward direction of the cleaning robot 100, that is, the first electrical connection portion 130 is disposed at the head of the body 110, and the second electrical connection portion 140 is located at the tail of the body 110. It is understandable that those skilled in the art can flexibly arrange the positions of the first electrical connection portion 130 and the second electrical connection portion 140, as long as they are spaced apart and do not interfere with each other's connection to the external circuit.

[0044] In some optional embodiments, the first electrical connection portion 130 of the cleaning robot 100 can be electrically connected to a charging station or a second electrical connection portion 140 of another cleaning robot 100 to charge the energy storage component 120.

Similarly, the subsequent cleaning robots 100 are electrically connected in the same order as the previous cleaning robot 100, that is, they are electrically connected in sequence. In this embodiment, the cleaning robots 100 are physically connected in series and electrically connected in parallel, meaning that the energy storage components 120 of the cleaning robots 100 are connected in parallel. This embodiment allows for an unlimited number of connected cleaning robots 100. Furthermore, because the circuitry of one cleaning robot 100 is connected in parallel, even if the circuitry of one cleaning robot 100 is damaged, it will not affect the charging of subsequent cleaning robots 100, resulting in enhanced safety and wide applicability.

[0046] In other optional embodiments, the first electrical connection portion 130 of the cleaning robot 100 can be electrically connected to a charging pile or the first electrical connection portion 130 of another cleaning robot 100, and the second electrical connection portion 140 of the cleaning robot 100 can be electrically connected to the second electrical connection portion 140 of another cleaning robot 100, so that the energy storage component 120 is charged. According to this embodiment, since the cleaning robots 100 have the same structure, when the first electrical connection portion 130 of the cleaning robot 100 is electrically connected to the first electrical connection portion 130 of another cleaning robot 100, and the second electrical connection portion 140 of the cleaning robot 100 is electrically connected to the second electrical connection portion 140 of another cleaning robot 100, the cleaning robots 100 of this embodiment can achieve same-end connection.

[0047] Specifically, in order to achieve same-end connection of the cleaning robot 100, the cleaning robot 100 of this embodiment further includes a circuit switching module 150, such as Figure 7As shown, the circuit switching module 150 is used to electrically connect the first electrical connection portion 130 to the energy storage assembly 120. The circuit switching module 150 can change the electrical connection mode between the first electrical connection portion 130 and the energy storage assembly 120. The circuit switching module 150 is used to implement circuit switching between two cleaning robots 100 connected through different electrical connections, so that no matter which electrical connection portion is used to electrically connect the two cleaning robots 100, power can be supplied to the energy storage assembly 120.

According to this embodiment, the cleaning robot 100 of the embodiment of the present application can achieve same-end connection or different-end connection through circuit switching.

[0049] In some optional embodiments, the circuit switching module 150 includes a double-pole double-throw relay or an H-bridge circuit. Specific circuit connection methods can be flexibly configured by those skilled in the art according to actual conditions, and will not be described in detail here.

[0050] like Figure 7 As shown, in other optional embodiments, the first pole piece 131 includes a first sub-pole piece 1311 and a second sub-pole piece 1312 electrically connected to each other, the first sub-pole piece 1311 is electrically connected to the energy storage component 120, the second sub-pole piece 1312 is electrically connected to the third pole piece 141, and the second pole piece 132 includes a third sub-pole piece 1321 and a fourth sub-pole piece 1322 electrically connected to each other, the third sub-pole piece 1321 is electrically connected to the energy storage component 120, and the fourth sub-pole piece 1322 is electrically connected to the fourth pole piece 142. According to this embodiment, the first electrical connection portion 130 realizes current transmission between two circuits through four sub-pole pieces, and each sub-pole piece operates independently to reduce interference.

[0051] Furthermore, the first pole piece 131 and the second pole piece 132 extend at least along the outer wall of the body 110, and the third pole piece 141 and the fourth pole piece 142 extend at least along the outer wall of the body 110. The first pole piece 131 and the second pole piece 132 are located at the same height on the outer wall of the body 110, and their height is not lower than that of the third pole piece 141 and the fourth pole piece 142. This ensures that the connection point of the first electrical connection portion 130 and the connection point of the second electrical connection portion 140 of the two cleaning robots 100 are at the same height, facilitating docking.

[0052] In some other preferred embodiments, the body 110 further includes a shell and a dust box assembly 160, see Figure 2 and Figure 3 The second electrical connection portion 140 is arranged on the dust box assembly 160, and the dust box assembly 160 is detachably mounted on the shell. The dust box assembly 160 is provided with a first power supply adapter electrode 161, and accordingly, the shell is provided with a second power supply adapter electrode matching the first power supply adapter electrode 161. The dust box assembly 160 is detachably mounted on the shell, so that the first power supply adapter electrode 161 and the second power supply adapter electrode are electrically connected or separated.

According to this embodiment, when the charged cleaning robot 100 sends a charging signal, the subsequent cleaning robot 100 can detect the charging signal and move to the charging signal location, planning an avoidance space to avoid moving directly to the charging location of the charging pile and colliding with the charging cleaning robot 100.
