[0045] The intermediate brush 200 is arranged on the mounting frame 100, and when the bottom surface in the carriage is concave, the size of the intermediate brush 200 in the left-right direction can be close to the width size of the drainage surface of the bottom surface in the carriage, the intermediate brush 200 is used for cleaning the drainage surface of the bottom surface in the carriage, and the intermediate brush 200 can be provided with a plurality of cleaning pieces 202, which can be bristles or steel wires, etc.

[0046] The two side brushes 300 are movably arranged on the mounting frame 100, and the two side brushes 300 are respectively located at both ends of the intermediate brush 200 in the left-right direction, when the bottom surface in the carriage is concave, the size of the side brush 300 can be close to the width size of the inclined surface of the bottom surface in the carriage, the side brush 300 is used for cleaning the inclined surface of the bottom surface in the carriage, and the side brush 300 can be provided with a plurality of cleaning pieces 202, which can be bristles or steel wires, etc.

[0047] The side brush 300 has a first state and a second state during movement, when the side brush 300 is in the first state, the bottom of the side brush 300 is level with the bottom of the intermediate brush 200, and the distance between the bottoms of the two ends of the side brush 300 away from each other can be close to the width size of the carriage. When the side brush 300 is in the second state, the side brush 300 extends upwardly and obliquely away from the intermediate brush 200, and the distance between the bottoms of the two ends of the side brush 300 away from each other can be close to the width size of the carriage.

[0048] In the present application, the horizontal brush assembly is mounted on the carriage cleaning device through the mounting frame 100, when the bottom surface in the carriage needs to be cleaned, the intermediate brush 200 and the two side brushes 300 are attached to the bottom surface in the carriage, and then the carriage cleaning device is started, and the carriage cleaning device drives the horizontal brush assembly to move forward.

[0049] When the bottom surface of the compartment is flat, the side brushes 300 are adjusted to the first state, and the bottom of the side brushes 300 is at the same height as the bottom of the middle brush 200, so that the side brushes 300 and the middle brush 200 are closely attached to the bottom surface of the compartment. When the bottom surface of the compartment is concave, the side brushes 300 are adjusted to the second state, and the side brushes 300 are inclined upward in the direction away from the middle brush 200, and the inclination angle of the side brushes 300 relative to the horizontal plane can be equal to the inclination angle of the inclined surface of the bottom surface of the compartment relative to the horizontal plane, so that the side brushes 300 and the middle brush 200 are closely attached to the bottom surface of the compartment, and the cross brush assembly can be applied to the bottom surface of the compartment with different shapes, and has good cleaning effect for the bottom surface of the compartment with different shapes.

[0050] Referring to Figure 1 and Figure 2 In some embodiments of the present application, one end of the side brush 300 close to the middle brush 200 is rotatably connected to the mounting frame 100, and the rotation axis of the side brush 300 extends in the front-rear direction. The mounting frame 100 is provided with an adjusting member 101 connected to the side brush 300 to drive the rotation of the side brush 300. The adjusting member 101 can be an oil cylinder, an air cylinder or an electric push rod, etc. When the adjusting member 101 is started, the side brush 300 can be rotated, and the side brush 300 can be adjusted to the first state and the second state during the rotation, which is simple in structure, convenient to operate and good in adjusting effect.

[0051] Referring to Figure 4 In some embodiments of the present application, the middle brush 200 is provided with movable brushes 201 at both ends in the left-right direction, the movable brushes 201 can move and adjust in the left-right direction, and the ends of the two movable brushes 201 away from each other are respectively provided with a plurality of cleaning members 202. When the side brush 300 is adjusted from the first state to the second state, the movable brushes 201 can move in the direction away from the middle brush 200, and when the side brush 300 is adjusted from the second state to the first state, the movable brushes 201 can move in the direction close to the middle brush 200. When the bottom surface of the compartment is concave, the side brush 300 needs to be rotated to the second state, and due to the deflection, there is a large gap between the side of the side brush 300 close to the middle brush 200 and the middle brush 200, which affects the cleaning of the corner between the drainage surface and the inclined surface of the bottom surface of the compartment.

[0052] In the embodiment, when the side brush 300 is moved from the first state to the second state, the movable brush 201 can be moved to the gap between the side brush 300 and the middle brush 200 in the direction away from the middle brush 200, and the plurality of cleaning pieces 202 on the movable brush 201 can be correspondingly moved to the corner between the drainage surface and the inclined surface of the bottom surface in the vehicle compartment, so that the corner between the drainage surface and the inclined surface of the bottom surface in the vehicle compartment can be thoroughly cleaned, and the cleaning effect is better. When the bottom surface in the vehicle compartment is a horizontal surface, the movable brush 201 is moved in the direction close to the middle brush 200, so that the plurality of cleaning pieces 202 on the movable brush 201 are close to the middle brush 200, and thus interference caused by the movement of the side brush 300 from the second state to the first state can be avoided.

When the side brush 300 is moved from the second state to the first state, the side brush 300 pushes the movable brush 201 to slide in the direction close to the middle brush 200, and the elastic piece 204 is contracted to generate an elastic restoring force. When the side brush 300 is moved from the first state to the second state, the movable brush 201 can be pushed to slide in the direction away from the middle brush 200 under the action of the elastic restoring force of the elastic piece 204, without the need for an additional driving piece to drive the movement of the movable brush 201, the structure is simpler, the degree of automation is higher, and the use is more convenient. Moreover, through the abutment of the side brush 300 and the elastic piece 204, the random sliding of the movable brush 201 can be reduced, and the cleaning effect is better.

[0054] It should be noted that the elastic piece 204 can be a spring, an elastic sheet or an elastic rubber block, etc.
