[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example

[0028] like Figure 1-2 As shown, this embodiment provides a mechanical collision detection device, including a housing portion 1, a bearing portion 2, a photoelectric sensor 3 and a transmission terminal 7, wherein an installation compartment 11 is provided in the housing portion 1;

[0030] The first cantilever 21 has a bent portion at the end, wherein the bent portion can be located in the photoelectric sensor 3 when the bearing portion 2 rotates. The second cantilever 22 is located outside the housing portion 1, wherein the housing portion 1 has a notch 13, and the second cantilever 22 is located outside the notch 13; the second cantilever 22 has a protruding portion at the end, and the protruding portion includes a V shape and an inverted V shape; when the sweeping robot equipped with the detection device in this embodiment is used, its normal state is as follows Figure 1 As shown, the bent portion of the second cantilever 22 is located in the photoelectric sensor 3. If the second cantilever 22 hits an obstacle, the bearing portion 2 will rotate, thereby driving the first cantilever 21 to rotate and leave the photoelectric sensor 3. Figure 2 At this time, the bent portion of the first cantilever 21 leaves the photoelectric sensor 3. Therefore, the circuit board 4 connected to the photoelectric sensor 3 transmits a signal to the sweeping robot through the transmission terminal 7. The sweeping robot makes an evasive action, thereby completing the collision detection.

The elastic member 6 will drive the first cantilever 21 to return to its original position to continue collision detection.

[0032] The photoelectric sensor 3 is installed on a circuit board 4 arranged in the installation compartment 11, wherein the circuit board 4 is also connected to a transmission terminal 7 for transmitting signals or information to the sweeping machine.

[0033] This embodiment also provides a sweeping robot having the aforementioned mechanical collision detection device, wherein at least two detection devices are provided.

[0034] Preferably, in this embodiment, the detection devices are respectively arranged at two opposite ends of the sweeping robot, and the detection devices can also be arranged on the sides and corners of the sweeping robot, so that the detection sensitivity is higher.

[0035] The detection device of the utility model realizes the processing of collision situations through mechanical detection, which is more sensitive. At least detection devices are arranged at both ends of the sweeping robot, which can effectively detect obstacles, improve the cleaning efficiency, and avoid affecting the user experience.
