[0042] Reference below Figures 1 to 6 A horizontal brush assembly and a vehicle compartment cleaning device according to an embodiment of the present invention are described.

[0043] According to the horizontal brush assembly of the first embodiment of the present invention, Figures 1 to 6 As shown, a mounting frame 100 , a middle brush 200 and two side brushes 300 are included.

[0044] The mounting frame 100 is used to be mounted on the carriage cleaning device so that the carriage cleaning device can drive the horizontal brush assembly to move and rise and fall along the front-rear direction of the carriage.

[0045] The middle brush 200 is arranged on the mounting frame 100. When the bottom surface in the car is concave, the left and right dimensions of the middle brush 200 can be close to the width of the drainage surface of the bottom surface in the car. The middle brush 200 is used to clean the drainage surface of the bottom surface in the car. The middle brush 200 can be provided with a plurality of cleaning parts 202, which can be bristles or steel wires, etc.

[0046] The two side brushes 300 can be movably arranged on the mounting frame 100, and the two side brushes 300 are respectively located at the two ends of the middle brush 200 along the left and right directions. When the bottom surface in the car 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 car. The side brush 300 is used to clean the inclined surface of the bottom surface in the car. The side brush 300 can be provided with a plurality of cleaning parts 202, and the cleaning parts 202 can be bristles or steel wires, etc.

[0047] The side brush 300 has a first state and a second state during its activity. When the side brush 300 is in the first state, the bottom of the side brush 300 is at the same height as the bottom of the middle brush 200, and the distance between the bottoms of the two ends of the side brushes 300 that are separated from each other can be close to the width of the compartment. When the side brush 300 is in the second state, the side brush 300 extends upward in a direction away from the middle brush 200, and the distance between the bottoms of the two ends of the side brushes 300 that are separated from each other can be close to the width of the compartment.

[0048] In the present invention, the horizontal brush assembly is installed on the carriage cleaning device through the mounting frame 100. When the bottom surface of the carriage needs to be cleaned, the middle brush 200 and the two side brushes 300 are made to fit the bottom surface of the carriage, and then the carriage cleaning device is started, and the carriage cleaning device drives the horizontal brush assembly to move forward.

[0049] According to the horizontal brush assembly of the embodiment of the present invention, when the bottom surface in the compartment is a flat horizontal surface, the side brushes 300 are movably adjusted to make the two side brushes 300 move to the first state, in which 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 can fit closely with the bottom surface in the compartment. When the bottom surface in the compartment is concave, the side brushes 300 are movably adjusted to make the two side brushes 300 move to the second state, in which the side brushes 300 extend upward in a 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 in the compartment relative to the horizontal plane, so that the side brushes 300 and the middle brush 200 can fit closely with the bottom surface in the compartment, thereby making the horizontal brush assembly applicable to the situation where the bottom surface in the compartment is of different shapes, and having a good cleaning effect for the bottom surfaces in the compartment of different shapes.

[0050] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present invention, 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-to-back direction. The mounting frame 100 is provided with an adjusting member 101, and the adjusting member 101 is connected to the side brush 300 to drive the side brush 300 to rotate. The adjusting member 101 can be an oil cylinder, an air cylinder or an electric push rod, etc., and the adjusting member 101 is started, and the adjusting member 101 can drive the side brush 300 to rotate. The side brush 300 can be adjusted to the first state and the second state during the rotation process, with a simple structure, convenient operation, and good adjustment effect.

[0051] refer to Figure 4 As shown, in some embodiments of the present invention, movable brushes 201 are respectively provided at both ends of the middle brush 200 in the left-right direction, and the movable brushes 201 can be moved and adjusted in the left-right direction. A plurality of cleaning members 202 are respectively provided at the ends of the two movable brushes 201 that are away from each other. When the side brush 300 moves from the first state to the second state, the movable brush 201 can move in a direction away from the middle brush 200. When the side brush 300 moves from the second state to the first state, the movable brush 201 can move in a direction close to the middle brush 200. When the bottom surface in the compartment is concave, the side brush 300 needs to be rotated to the second state. Due to the deflection, there will be a large gap between the side of the side brush 300 close to the middle brush 200 and the middle brush 200, which will affect the cleaning of the corner between the drainage surface and the inclined surface of the bottom surface in the compartment.

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

[0053] refer to Figure 5 As shown, in some embodiments of the present invention, the middle brush 200 is provided with sliding holes 203 at both ends along the left and right directions, the movable brush 201 is slidably installed in the corresponding sliding holes 203, an elastic member 204 is provided between the inner end of the movable brush 201 and the inner end of the sliding hole 203, and the side brush 300 abuts against the outer end of the corresponding movable brush 201. When the side brush 300 moves 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 member 204 contracts to generate an elastic restoring force. When the side brush 300 moves from the first state to the second state, under the action of the elastic restoring force of the elastic member 204, the movable brush 201 can be pushed to slide in the direction away from the middle brush 200, without the need to set an additional driving member to drive the movable brush 201 to move, the structure is simpler, the degree of automation is higher, and the use is more convenient. Moreover, through the abutment between the side brush 300 and the elastic member 204, the situation of random sliding of the movable brush 201 can be reduced, and the cleaning effect is better.

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

[0055] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present invention, when the side brush 300 is in the first state, the distance between the bottoms of the two side brushes 300 that are away from each other is L1, and when the side brush 300 is in the second state, the distance between the bottoms of the two side brushes 300 that are away from each other is L2, satisfying: L1 = L2. Regardless of whether the bottom surface in the compartment is a horizontal surface or a concave shape, the width dimension in the compartment is generally the same. In this embodiment, regardless of whether the side brush 300 is in the first state or the second state, the distance between the bottoms of the two side brushes 300 that are away from each other remains unchanged. In this way, it can be applied to the situation where the bottom surface in the compartment is of different shapes, without the need to additionally adjust the size of the side brush 300 or the middle brush 200, which is more convenient to use and more practical.

[0056] refer to Figure 3 As shown, in some embodiments of the present invention, the horizontal brush assembly further includes a suction cylinder 400, a first dust cover 500 and two second dust covers 600, the suction cylinder 400 is arranged on the mounting frame 100 for connecting an external suction device, the first dust cover 500 is arranged on the front side of the middle brush 200, the first dust cover 500 is connected to the suction cylinder 400, the two second dust covers 600 are respectively arranged on the front sides of the two side brushes 300, and the second dust covers 600 are connected to the suction cylinder 400. For example, the first dust cover 500 can extend to both ends of the middle brush 200 in the left-right direction, and when the side brush 300 moves to the first state, the second dust cover 600 can extend to both ends of the corresponding side brush 300 in the left-right direction.

[0057] In this embodiment, when the middle brush 200 and the side brush 300 move forward along the carriage, the material and dust on the bottom surface of the carriage will gradually accumulate on the front side of the middle brush 200 and the front side of the side brush 300. In this embodiment, a suction cylinder 400, a first dust hood 500 and two second dust hoods 600 are provided. When the accumulated material and dust are large, the suction device can be started. The suction device sucks the material and dust accumulated on the front side of the middle brush 200 and the front side of the side brush 300 through the suction cylinder 400, the first dust hood 500 and the two second dust hoods 600, and the cleaning effect is better.

[0058] refer to Figure 3 As shown, in some embodiments of the present invention, the horizontal brush assembly also includes a first scraper 700, a second scraper 800 and a third dust hood 900. The first scraper 700 can be raised and lowered on the mounting frame 100 and is located on the front side of the first dust hood 500 and the second dust hood 600. The first scraper 700 includes a first middle plate 701 and two first side plates 702. The first middle plate 701 extends along the left and right directions to both ends of the middle brush 200. The two first side plates 702 are respectively connected to both ends of the first middle plate 701. The first side plate 702 extends upward in a direction away from the first middle plate 701. The inclination angle of the first side plate 702 relative to the horizontal plane can be equal to the inclination angle of the side brush 300 relative to the horizontal plane when it is in the second state. The ends of the two first side plates 702 that are away from each other can extend to the ends of the two side brushes 300 that are away from each other when they are in the second state. The second scraper 800 can be raised and lowered on the mounting frame 100 and is located in front of the first dust hood 500 and the second dust hood 600. The second scraper 800 extends in the left-right direction, and both ends of the second scraper 800 in the left-right direction can extend to the end that is away from each other when the two side brushes 300 are in the first state. The bottoms of the first scraper 700 are at the same height. The third dust hood 900 is provided on the mounting frame 100 and is located in front of the first scraper 700 and the second scraper 800. The third dust hood 900 can extend in the left-right direction to both ends of the first middle plate 701, and the third dust hood 900 is connected to the suction cylinder 400.

[0059] In addition to fine materials and dust, there may also be large block materials in the carriage. In addition, there may be more materials on the bottom surface of the carriage, which makes it difficult to clean directly with the middle brush 200 and the side brush 300, and it is easy to damage the middle brush 200 and the side brush 300. In this embodiment, the first scraper 700 or the second scraper 800 can be used to scrape off the larger and more materials on the bottom surface of the carriage. When the materials on the front side of the first scraper 700 or the second scraper 800 accumulate more, the suction device can be started. The suction device can quickly remove the materials accumulated on the front side of the first scraper 700 or the second scraper 800 through the suction cylinder 400 and the third dust cover 900, so as to facilitate the subsequent cleaning of the remaining materials and dust by the middle brush 200 and the side brush 300, and the cleaning is more thorough, the cleaning effect is better, and the middle brush 200 and the side brush 300 are not easily damaged. In addition, the first scraper 700 is just suitable for the situation where the bottom surface in the car is concave, and the second scraper 800 is just suitable for the situation where the bottom surface in the car is horizontal, and the first scraper 700 and the second scraper 800 can be raised and lowered, so that when the bottom surface in the car is concave, the second scraper 800 can be raised to separate from the bottom surface in the car, and the first scraper 700 can be lowered to fit with the bottom surface in the car; when the bottom surface in the car is horizontal, the first scraper 700 can be raised to separate from the bottom surface in the car, and the second scraper 800 can be lowered to fit with the bottom surface in the car. In this way, it can be applicable to the situation where the bottom surface in the car is of different shapes, which is more convenient to use, has better cleaning effect and better practicality.

[0060] refer to Figure 3 As shown, in some embodiments of the present invention, the second scraper 800 includes a second middle plate 801 and two second side plates 802, the second middle plate 801 extends in the left-right direction to both ends of the middle brush 200, the two second side plates 802 are respectively connected to the two ends of the second middle plate 801, the first side plate 702 extends forwardly and obliquely in a direction away from the first middle plate 701, and the second side plate 802 extends forwardly and obliquely in a direction away from the second middle plate 801. In this embodiment, the two first side plates 702 of the first scraper 700 extend forward in an inclined direction away from the first middle plate 701, and the two second side plates 802 of the second scraper 800 extend forward in an inclined direction away from the second middle plate 801. Therefore, when the first scraper 700 or the second scraper 800 moves forward, the two first side plates 702 of the first scraper 700 and the second side plates 802 of the second scraper 800 can just guide the materials on both sides of the bottom surface of the carriage to the middle of the bottom surface of the carriage, that is, the front side of the first middle plate 701 or the second middle plate 801, thereby facilitating the third dust hood 900 to perform concentrated suction, resulting in better suction effect and higher suction efficiency.

[0061] refer to Figures 1 to 3 as well as Figure 6 As shown, in some embodiments of the present invention, the mounting frame 100 is provided with a lifting cylinder 102, and the lifting cylinder 102 is formed with two oil chambers 103 arranged side by side. A piston 104 that can slide up and down is installed in the oil chamber 103, and is separated by the piston 104 to form a rod chamber 105 and a rodless chamber 106. The two rodless chambers 106 are connected, and a piston rod 107 is provided at the bottom end of the piston 104. The first scraper 700 and the second scraper 800 are respectively connected to the two piston rods 107. For example, both of the two rod chambers 105 can be provided with an oil pipe 108, and connected to an external hydraulic system through the oil pipe 108. Since the two rodless chambers 106 are connected, the overall oil in the two rodless chambers 106 remains unchanged. Then, when one of the oil pipes 108 inputs oil into the corresponding rod chamber 105, the corresponding piston 104 will rise, and the oil in the corresponding rodless chamber 106 will decrease and enter the other rodless chamber 106, thereby pushing the other piston 104 down, and the rising size of one piston 104 is equal to the falling size of the other piston 104. In this way, it is convenient for the first scraper 700 and the second scraper 800 to alternately rise and fall, so as to be suitable for the situation where the bottom surface of the car body has different shapes, without the need to be driven by different driving parts. The structure is simpler and the operation is more convenient. In addition, the first scraper 700 and the second scraper 800 will not rise or fall at the same time, thereby reducing the operating error rate and being more convenient to use.

[0062] It should be noted that one of the rodless cavities 106 may also be connected to an oil pipe 108 to facilitate the input of the required oil into the two rodless cavities 106.
