Side brush mechanism for vehicles of different widths

Abstract

This application relates to a side brush mechanism applicable to vehicles of different widths. The side brush mechanism includes a mounting base, a main frame rotatably mounted on the mounting base, a first limiting member and a second limiting member disposed on the mounting base, a first abutting member disposed on the main frame, and a second abutting member and a first driver movably mounted on the main frame. The first driver drives the second abutting member to have a first height position and a second height position in the height direction. When the second abutting member is in the first height position, it abuts against and is limited by the second limiting member; when the second abutting member is in the second height position, it is higher than the second limiting member to avoid the second limiting member. Thus, during the rotation of the main frame, by controlling the switching of the height position of the second abutting member, the main frame is limited by a first rotation angle at the first limiting member or a second rotation angle at the second limiting member, so that the brush body mounted on the main frame can adapt to the washing needs of vehicles of different widths.

Description

Technical Field

[0001] This application relates to the field of vehicle cleaning technology, and in particular to a side brush mechanism applicable to vehicles of different widths. Background Technology

[0002] In the field of rail transit vehicle operation and maintenance, trains need to undergo daily preparation before entering the depot and cleaning before leaving the depot to meet the hygiene standards and appearance maintenance requirements for high-frequency operation. The side washing equipment currently widely used consists of multiple sets of rotating brushes, which clean the surface of the car body through mechanical contact friction.

[0003] However, the trains entering the depot are often different, and their body widths also vary. Therefore, when washing the sides, the amount of hair picked up by the train body will differ, which may result in the train body not being cleaned properly or having too much hair picked up. Utility Model Content

[0004] Therefore, it is necessary to provide a side brush mechanism applicable to vehicles of different widths to address the aforementioned problems.

[0005] A side brush mechanism applicable to vehicles of different widths includes:

[0006] Mounting base;

[0007] The main frame is rotatably mounted on the mounting base;

[0008] The first limiting member and the first abutting member are provided. The first limiting member is provided on the mounting base and the first abutting member is provided on the main frame. The main frame is rotated to make the first abutting member suitable for abutting and limiting with the first limiting member.

[0009] The second limiting member is disposed on the mounting base and along the rotation direction of the main frame. The second limiting member is spaced apart from the first limiting member, and the second limiting member is located on the side of the first limiting member away from the main frame.

[0010] The second abutment is movably mounted on the main frame and is located between the first and second limiting members along the rotation direction of the main frame.

[0011] The first driver is mounted on the main frame. The first driver drives the second abutment to have a first height position and a second height position in the height direction. When the second abutment is in the first height position, the second abutment is adapted to abut and limit the second limit member. When it is in the second height position, the second abutment is higher than the second limit member to avoid the second limit member.

[0012] The aforementioned side brush mechanism includes a mounting base, a main frame rotatably mounted on the mounting base, a first limiting member and a second limiting member disposed on the mounting base, a first abutting member disposed on the main frame, and a second abutting member and a first driver movably assembled on the main frame.

The first driver drives the second abutting member to have a first height position and a second height position in the height direction: when the second abutting member is at the first height position, it abuts against and is limited by the second limiting member; when the second abutting member is at the second height position, it is higher than the second limiting member to avoid it. Thus, during the rotation of the main frame, by controlling the switching of the height position of the second abutting member, the main frame can be limited by a first rotation angle at the first limiting member or a second rotation angle at the second limiting member, allowing the brush body mounted on the main frame to adapt to the washing needs of vehicles with different widths.

[0013] In one embodiment, the side brush mechanism further includes a bearing assembly, which includes a bearing housing, a bearing, and a shaft. The bearing housing is mounted on the main frame, and the shaft is mounted on the bearing to be rotatably mounted on the main frame. The axial direction of the shaft is perpendicular to the height direction.

[0014] The second abutment is fixedly mounted on the shaft, and the first driver is used to drive the shaft to rotate.

[0015] In one embodiment, the side brush mechanism further includes a slide rail assembly, which includes a guide rail extending along the height direction, and two guide rails are spaced apart in a direction perpendicular to the height direction to form an avoidance gap.

[0016] During the rotation of the main frame, the second limiting member is adapted to pass through the clearance gap;

[0017] The second abutment is slidably mounted on the slide rail assembly.

[0018] In one embodiment, the first abutting member includes a first abutting body and a first buffer member, the first buffer member being disposed on the first abutting body, the first abutting body being disposed on the main frame, and the first buffer member being adapted to abut and limit the first limiting member; and / or,

[0019] The second abutting member includes a second abutting body and a second buffer member. The second buffer member is disposed on the second abutting body, and the second abutting body is disposed on the main frame. The second buffer member is adapted to abut and limit the second limiting member.

[0020] In one embodiment, the first actuator is a cylinder.

[0021] In one embodiment, the first limiting member and / or the second limiting member are movably mounted on the mounting base along the rotation direction of the main frame.

[0022] In one embodiment, a first cross arm and a second cross arm are vertically connected to a first rotating shaft and are disposed at intervals, and are mounted on a mounting base.

[0023] The main frame also includes: a second rotating shaft and a second driver, the second rotating shaft being rotatably mounted between the first cross arm and the second cross arm, and the second driver driving the second rotating shaft to rotate.

[0024] In one embodiment, the side brush mechanism further includes a brush body disposed on the second rotating shaft.

[0025] In one embodiment, the outer contour of the brush body is an arc shape along the axial direction of the second rotating shaft.

[0026] In one embodiment, the side brush mechanism further includes a controller that controls the first driver to selectively drive the second abutment to move;

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] See Figures 1 to 6 As shown, the side brush mechanism 100 for vehicles of different widths according to this application includes a mounting base 1, a main frame 2, a first limiting member 31, a first abutting member 32, a second limiting member 41, and a first driver 5. The main frame 2 is rotatably mounted on the mounting base 1, and both the first limiting member 31 and the second limiting member 41 are assembled on the mounting base 1. Along the rotation direction of the main frame 2, the first limiting member 31 and the second limiting member 41 are arranged sequentially, with the second limiting member 41 located on the side opposite to the first limiting member 31, and the second limiting member 41 and the first limiting member 31 are spaced apart.

[0043] Both the first abutment 32 and the second abutment 42 are disposed on the main frame 2. In the rotation direction of the main frame 2, the first abutment 32 is located between the main frame 2 and the first limiting member 31, and the second abutment 42 is located between the first limiting member 31 and the second limiting member 41. When the main frame 2 rotates at different angles, when the main frame 2 rotates at one angle, the first abutment 32 is adapted to abut and limit the first limiting member 31; when the main frame 2 rotates at another angle, the second abutment 42 is adapted to abut and limit the second limiting member 41. Thus, the main frame 2 has two fixed rotation angles. It should be understood that in some embodiments of this application, the side brush mechanism 100 also includes a brush body 8, which is disposed on the main frame 2. Because the main frame 2 has two fixed rotation angles, the brush body 8 is used to brush vehicle bodies of different widths.

[0044] The first driver 5, mounted on the main frame 2, is drively connected to the second abutment 42. The first driver 5 drives the second abutment 42 to move in the height direction, so that the second abutment 42 has a first height position and a second height position in the height direction. See, for example. Figure 5 As shown, when the second abutting member 42 is in the first height position, the second abutting member 42 is adapted to abut and limit the second limiting member 41; for example, see [reference needed]. Figure 2 As shown, at the second height position, the second abutment 42 is higher than the second limiting member 41 to avoid the second limiting member 41. It should be understood that when the first abutment 32 needs to abut against the first limiting member 31, the first driver 5 needs to drive the second abutment 42 to the second height position so that the second abutment 42 avoids the second limiting member 41 in the height direction; in other words, the height of the second abutment 42 is higher than the second limiting member 41. Thus, during the rotation of the main frame 2, along the rotation direction of the main frame 2, the second abutment 42 can move to the side of the second limiting member 41 away from the first limiting member 31, allowing the main frame 2 to have a larger rotation angle, thereby enabling the first abutment 32 to abut against the first limiting member 31.

[0045] In summary, the side brush mechanism 100 provided in this application includes a mounting base 1, a main frame 2 rotatably mounted on the mounting base 1, a first limiting member 31 and a second limiting member 41 disposed on the mounting base 1, a first abutting member 32 disposed on the main frame 2, and a second abutting member 42 and a first driver 5 movably assembled on the main frame 2. Specifically, along the rotation direction of the main frame 2, the second limiting member 41 is spaced apart from the first limiting member 31, and the second limiting member 41 is located on the side of the first limiting member 31 facing away from the main frame 2; the second abutting member 42 is located between the first limiting member 31 and the second limiting member 41. The first driver 5 drives the second abutting member 42 to have a first height position and a second height position in the height direction: when the second abutting member 42 is in the first height position, it abuts and limits the second limiting member 41; when the second abutting member 42 is in the second height position, it is higher than the second limiting member 41 to avoid the second limiting member 41. Therefore, during the rotation of the main frame 2, by controlling the height position switching of the second abutment member 42, the main frame 2 can achieve the first rotation angle limit at the first limit member 31 or the second rotation angle limit at the second limit member 41, so that the brush body 8 installed on the main frame 2 can adapt to the car body washing needs of different widths.

[0046] See Figure 2 and Figure 5 As shown, in some embodiments of this application, the side brush mechanism 100 further includes a bearing assembly 6. The bearing assembly 6 includes a bearing seat 61, a bearing 62, and a shaft 63. The bearing seat 61 is mounted on the main frame 2, and the shaft 63 is rotatably mounted on the bearing seat 61 by being mounted on the bearing 62. It should be understood that the axial direction of the shaft 63 is perpendicular to the height direction. A second abutment 42 is fixedly mounted on the shaft 63, and a first driver 5 is used to drive the shaft 63 to rotate. Thus, when the first driver 5 drives the shaft 63 to rotate, the second abutment 42 fixed to the shaft 63 rotates synchronously with the shaft 63, thereby achieving position switching of the second abutment 42 in the height direction. When the shaft 63 rotates to a first angle, the second abutment 42 is at a first height position, abutting and limiting the second limiting member 41; when the shaft 63 rotates to a second angle, the second abutment 42 is at a second height position, higher than the second limiting member 41 to avoid limiting obstacles.

[0047] In some embodiments of this application, the side brush mechanism 100 further includes a slide rail assembly (not shown in the figures). The slide rail assembly includes guide rails that extend along the height direction. It should be understood that the two guide rails are spaced apart in a direction perpendicular to the height direction, which can also be understood as the two guide rails being spaced apart in the width direction. This allows the second limiting member 41 to pass through the clearance gap during the rotation of the main frame 2. When the main frame 2 rotates toward the first limiting member 31, the second limiting member 41 passes through the clearance gap, avoiding interference with the slide rail assembly.

[0048] The second abutment 42 is slidably mounted on the slide rail assembly, allowing it to slide up and down along the slide rail assembly to change its height position. Thus, when the first driver 5 drives the second abutment 42 to move, the second abutment 42 slides along the guide rail in the height direction, switching between the first and second height positions. When the second abutment 42 slides to the first height position, it is adapted to abut against and be limited by the second limiting member 41; when the second abutment 42 slides to the second height position, it is higher than the second limiting member 41 to avoid limiting obstacles.

[0049] See Figure 2 and Figure 5 As shown, in some embodiments of this application, the first abutting member 32 includes a first abutting body 321 and a first buffer member 322. The first buffer member 322 is disposed on the first abutting body 321, and the first abutting body 321 is disposed on the main frame 2. The first buffer member 322 is adapted to abut and limit the first limiting member 31. And / or, the second abutting member 42 includes a second abutting body 421 and a second buffer member 422. The second buffer member 422 is disposed on the second abutting body 421, and the second abutting body 421 is disposed on the main frame 2. The second buffer member 422 is adapted to abut and limit the second limiting member 41.

[0050] For example, in some embodiments of this application, both the first abutting body 321 and the second abutting body 421 are made of materials with a certain strength, such as metal, thereby providing structural strength for the first abutting member 32 and the second abutting body 421. Additionally, both the first buffer member 322 and the second buffer member 422 are made of elastic materials (such as rubber). Thus, during the abutting and limiting process, the first buffer member 322 and the second buffer member 422 absorb energy through deformation, reducing mechanical impact.

[0051] See Figure 2 and Figure 5As shown, in some embodiments of this application, the first actuator 5 is a cylinder. It should be understood that since the cylinder uses gas as the transmission medium, and gas is compressible, the first actuator 5 can absorb impact energy through gas compression when the second abutment 42 and the second limiting member 41 abut and are limited. Therefore, when the main frame 2 rotates to the moment the second abutment 42 and the second limiting member 41 abut, the buffering effect formed by gas compression can significantly reduce mechanical impact and improve the durability of the side brush mechanism 100. Furthermore, when the piston rod of the cylinder is fully retracted, the position of the second abutment 42 is locked without the need for an additional limiting mechanism. Therefore, selecting a cylinder as the first actuator 5 simplifies the structure of the side brush mechanism 100 and improves its operability.

[0052] In some of the embodiments described above, the first driver 5 is taken as a cylinder, but this application is not limited thereto. For example, the first driver 5 can be a drive motor.

[0053] See Figure 2 and Figure 5 As shown, in some embodiments of this application, along the rotation direction of the main frame 2, the first limiting member 31 is movably mounted on the mounting base 1; and / or, the second limiting member 41 is movably mounted on the mounting base 1. It should be understood that by adjusting the mounting positions of the first limiting member 31 and / or the second limiting member 41 on the mounting base 1, the abutment positions of the first abutment member 32 and the first limiting member 31, and / or the abutment positions of the second abutment member 42 and the second limiting member 41, can be changed. Therefore, the fixed rotation angle of the main frame 2 can be adaptively adjusted according to actual washing needs, significantly improving the applicability of the side brush mechanism 100 to vehicles of different specifications.

[0054] For example, see Figure 2 and Figure 5 As shown, the mounting base 1 is provided with a first strip-shaped hole and a second strip-shaped hole, both extending along the rotation direction of the main frame 2. A first limiting member 31 is slidably mounted in the first strip-shaped hole, and a second limiting member 41 is slidably mounted in the second strip-shaped hole. By adjusting the mounting position of the first limiting member 31 in the first strip-shaped hole, the relative position of the first limiting member 31 and the main frame 2 in the rotation direction can be changed; by adjusting the mounting position of the second limiting member 41 in the second strip-shaped hole, the relative position of the second limiting member 41 and the main frame 2 in the rotation direction can be changed. Therefore, the contact positions of the first abutting member 32 and the first limiting member 31, and the contact positions of the second abutting member 42 and the second limiting member 41, can be precisely adjusted, allowing the fixed rotation angle of the main frame 2 to be adaptively adjusted according to actual washing needs, significantly improving the applicability of the side brush mechanism 100 to vehicles of different specifications.

[0055] See Figures 1 to 6As shown, in some embodiments of this application, the main frame 2 includes a first rotating shaft 21, a first cross arm 22, a second cross arm 23, a second rotating shaft 24, and a second driver 25. The first rotating shaft 21 is rotatably mounted on the mounting base 1. It should be understood that the rotation direction of the first rotating shaft 21 is the same as the rotation direction of the main frame 2. The first cross arm 22 and the second cross arm 23 are perpendicularly connected to the first rotating shaft 21, and are spaced apart along the axial direction of the first rotating shaft 21. It should be noted that the first cross arm 22 and the second cross arm 23 are parallel to each other along the axial direction of the first rotating shaft 21.

[0056] The second rotating shaft 24 is rotatably mounted between the first cross arm 22 and the second cross arm 23, allowing the second rotating shaft 24 to rotate around its own circumference. Furthermore, the second rotating shaft 24 is also connected to the second driver 25, enabling the second driver 25 to drive the second rotating shaft 24 to rotate. It should be understood that the second rotating shaft 24 is used to mount the brush body 8. When the second driver 25 drives the second rotating shaft 24 to rotate, it causes the brush body 8 to perform a rotating brushing action. Thus, the first rotating shaft 21 enables overall angle adjustment of the main frame 2, and the second rotating shaft 24 enables active rotation of the brush body 8; the two work together to achieve efficient cleaning of the vehicle's sides.

[0057] In some embodiments of this application, the brush body 8 and the second rotating shaft 24 are considered as two independent parts, with the brush body 8 assembled to the second rotating shaft 24. For example, the brush body 8 may be detachably assembled to the second rotating shaft 24, or the brush body 8 may be permanently fixed to the second rotating shaft 24. In one embodiment of this application, the brush body 8 is detachably assembled to the second rotating shaft 24. Because the brush body 8 experiences wear due to friction with the vehicle body, its brushing ability decreases over long-term use. Since the brush body 8 is detachably assembled to the second rotating shaft 24, it can be replaced individually, which helps reduce the maintenance cost of the side brush mechanism 100.

[0058] See Figure 2 As shown, in some embodiments of this application, the outer contour of the brush body 8 is arc-shaped along the axial direction of the second rotating shaft 24. It should be understood that since the outer surface of a vehicle body typically has curved features, the arc-shaped outer contour matches the geometry of the vehicle body's curved surface. Therefore, when the second actuator 25 drives the brush body 8 to rotate and brush, the arc-shaped outer contour can continuously conform to the vehicle body surface, significantly improving the cleaning effect. Of course, in some embodiments of this application, the outer contour of the brush body 8 can also be a straight line along the axial direction of the second rotating shaft 24.

[0059] In some embodiments of this application, the side brush mechanism 100 further includes a controller and a proximity switch. The controller is electrically connected to the first driver 5 and controls the first driver 5 to selectively drive the second abutment 42 to move in the height direction. The proximity switch is configured to monitor the position state of the second abutment 42 and is communicatively connected to the controller.

[0060] For example, in one embodiment of this application, the side brush mechanism 100 has a wide-car mode and a narrow-car mode. In the wide-car mode, the second abutment 42 is at a first height position, so that during the rotation of the main frame 2, the second abutment 42 is adapted to abut and limit the second limiting member 41. In the narrow-car mode, the second abutment 42 is at a second height position, so that during the rotation of the main frame 2, the second abutment 42 avoids the second limiting member 41, allowing the second abutment 42 to move in the rotation direction of the main frame 2 to a position where the second limiting member 41 is located on the side opposite to the first limiting member 31, thus allowing the first limiting member 31 to abut and limit the first abutment 32.

[0061] For example, in the initial state, the second abutment member 42 is in the second height position, and a proximity switch is set to provide feedback on the correctness of its position. In wide vehicle mode, after the second abutment member 42 moves to the first height position, the main frame 2 can perform the swing-out action (i.e., drive the brush body 8 set on the main frame 2 towards the vehicle body). Then, after the washing operation is completed and the main frame 2 returns to the initial position, the second abutment member 42 can perform the return-to-position action, switching the second abutment member 42 from the first height position to the second height position. In narrow vehicle mode, the second abutment member 42 should always be in the initial state of the second height position. Once the proximity switch feedback signal is lost, the current main frame 2 should immediately stop washing the vehicle and quickly return to its original position.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
