[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0028] Embodiment 1:

[0029] This embodiment provides a buffer type anti-collision device, such as Figures 1 to 5 , including an anti-collision beam 1, a fixing component, an anti-collision connection component, an elastic component and a sensor. The anti-collision beam 1 can be detachably mounted on the anti-collision connection component. The anti-collision connection component is connected to the fixing component through an elastic component. The fixing component is used to be mounted on external equipment. The sensor is connected to the external equipment signal and is used to sense the anti-collision beam 1 or the fixing drum component. Among them, the sensor can be selected as a proximity sensor, which can be installed at the bottom of the vehicle, the fixing component and other positions to sense the anti-collision beam 1; the sensor can also be installed on the anti-collision beam 1 or the connecting plate 2. When the anti-collision beam 1 is close to the fixing component or the sweeper, the sensor can also sense the fixing component or the sweeper, thereby triggering a signal and transmitting it to the control center of the sweeper to stop the sweeper.

[0030] Specifically, Figure 1 and Figure 2 As shown, when the anti-collision beam 1 collides with the external equipment, the anti-collision connection component squeezes the elastic component, so that the distance between the anti-collision beam 1 and the anti-collision connection component is reduced, and the sensor generates a sensing signal, and the external equipment stops moving. Among them, there are multiple groups of elastic components, and the multiple groups of elastic components are evenly distributed on the anti-collision connection component, such as Figure 1The anti-collision beam 1 shown can be optionally set to a straight type, and the connecting plate 2, which is also an anti-collision fixing component, is also set to a straight type. The elastic components are evenly distributed on the connecting plate 2. For example, the elastic components can be divided into two rows, and both rows are provided with 3 groups of elastic components. The elastic components are arranged at equal intervals. Therefore, when impacted, it can ensure that the anti-collision beam 1 is subjected to uniform force, thereby effectively and timely triggering the sensor, so that the equipment installed with the buffering anti-collision device of this embodiment can stop in time, such as a sweeper, which can stop in time when a collision occurs, thereby reducing the probability of damage to the sweeper, and also reducing the possibility of the sweeper affecting the surrounding environment due to the collision.

[0031] Optional, such as Figures 3 to 5 As shown, the anti-collision connection assembly includes a connection plate 2 , the connection plate 2 is provided with a mounting slide groove 3 , the anti-collision beam 1 is provided with a mounting rail 4 , and the mounting rail 4 is assembled in the mounting slide groove 3 .

[0032] Specifically, the anti-collision beam 1 is provided between the connecting plates 2 in a structure that is easy to disassemble, such as Figure 3 As shown, the two ends of the anti-collision beam 1 are provided with mounting rails 4 with a radial cross section similar to a T-shaped structure, so that the anti-collision beam 1 can be slid out or inserted from both sides of the connecting plate 2 during disassembly and assembly, and then the anti-collision beam 1 can be fixed by setting plugs on both sides of the anti-collision beam 1. The structure of setting the plugs is a prior art and will not be described here. Furthermore, the anti-collision beam 1 can be made of a lightweight composite material to reduce the vibration force on the vehicle. Of course, other materials can also be used, and it can be set according to actual needs.

The guide sleeve 7 is fixed to the fixed component, and the guide column 6 is slidably assembled in the guide sleeve 7.

[0034] Specifically, one end of the guide column 6 is fixed to the connecting member 5 by a locking member 9 such as a nut, and the nut at the other end is limited by the guide sleeve 7 and is set in the fixing assembly, so that the guide column 6 can slide in the guide sleeve 7 and will not be separated from the fixing assembly and the connecting plate 2. Figure 3 In the direction shown, when impacted, the connecting plate 2 pushes the guide column 6 to move to the right, compressing the spring 8. When the detection distance of the sensor is reached, the sensor sends a signal to the sweeper, and the sweeper stops moving; when there is no collision, the spring 8 resets, causing the anti-collision beam 1 to reset.

[0035] Further, such as Figure 2As shown, the connector 5 is provided with a plurality of connectors, and the shape of the connector 5 is U-shaped, and the connector 5 is provided with a through hole. One end of the guide column 6 is penetrated through the through hole and locked by the locking member 9.

As another embodiment, the connector 5 can also be provided as a connecting rod, the connector 5 has a certain length, and is provided with through holes arranged at equal intervals. All elastic components are installed on the connector 5, which can also achieve the connection effect.

[0036] like Figure 2 As shown, the fixing assembly of this embodiment includes a fixing connecting rod 10 and a mounting fixing unit. The fixing connecting rod 10 is provided with a plurality of connecting holes 11. The guide sleeve 7 is fixedly assembled in the connecting holes 11.
