Description

Technical Field

[0001] The present invention relates to the technical field of car washing equipment, and in particular to a deflection detection module, a vertical brush device and a car washing machine. Background Art

[0002] Car washers are used to wash cars. They mainly have functions such as blowing, spraying water and brushing. They can effectively remove dirt attached to the surface of the car and have the characteristics of high efficiency and energy saving. A general car wash machine uses a horizontal brush device and a vertical brush device to achieve brushing of the top and side of the car. Among them, in some technical solutions, the vertical brush is set to a multi-directional deflectable structure, so as to adapt to brushing irregular curved surface parts of the car surface and improve the brushing efficiency. It can be understood that when brushing, when the deflection angle of the vertical brush is appropriate, it can have an appropriate brushing force on the surface to be brushed, and the vertical brush can brush normally. When the position of the vertical brush is abnormal, for example, the deflection angle of the vertical brush is too large or too small, the brushing effect is not good, and it often needs to be re-cleaned, which affects the cleaning efficiency, or causes the distance between the central axis and the surface to be brushed to be too large or too small, causing damage to the surface of the car.

[0043] Figure 1 A schematic structural diagram of a vertical brush device according to an embodiment of the present invention, Figure 2 is a schematic diagram of a deflection detection module according to an embodiment of the present invention, Figure 3 for Figure 2 Top view of Figures 1 to 3The first embodiment of the present invention provides a deflection detection module for detecting whether the deflection angle of the vertical brush in the vertical brush device is too large. The deflection detection module includes a sensor 100 and a sensor 200. The sensor 200 includes a mounting section 210 and a sensing section 220. The mounting section 210 is used to connect the vertical brush. The mounting section 210 can be directly connected to the vertical brush or indirectly connected to the vertical brush through other components. Therefore, the sensor 200 can swing with the deflection of the vertical brush. Specifically, the mounting section 210 can be connected to the central axis 410 of the vertical brush. The sensing section 220 includes a sensing portion 221 and an avoidance portion 226. The avoidance portion 226 is connected to the mounting section 210. The position of the sensor 100 corresponds to the position of the sensing portion 221 on the sensing element 200. The sensing portion 221 can be sensed within a set range. The sensing portion 221 can move relative to the sensor 100 as the sensing element 200 swings. Therefore, when the vertical brush is deflected, the sensing element 200 swings accordingly, thereby causing the sensing portion 221 to move relative to the sensor 100.

[0044] When the sensing part 221 moves relative to the sensor 100 to deviate from the set range, the detection signal of the sensor 100 changes. Therefore, when the deflection angle of the vertical brush is too large, the sensing part 221 moves relatively much relative to the sensor 100, thereby deviating from the set range, and thus the sensing signal of the sensor 100 changes. The avoidance part 226 is used to avoid the induction of the sensor 100 at one end of the sensing part 221 facing the mounting section 210, so as to ensure that when the sensing part 221 deviates from the set range, the position between the sensing part 221 and the mounting section 210 can avoid the induction of the sensor 100, thereby being able to sense the sensing part 221 deviating in various directions, so as to detect whether the deflection angle of the vertical brush in various directions exceeds the preset range, so as to prompt an abnormality.

[0045] In the above embodiment, the sensor 100 can be a sensor commonly used in automation equipment for detecting whether there is material at a set position, such as a photoelectric sensor, so that the position of the photoelectric sensor corresponds to the position of the sensing part 221 on the sensing element 200, and the sensing part 221 is shielded from the light beam of the photoelectric sensor, so that it can be sensed by the photoelectric sensor. When the vertical brush deflects to move the sensing part 221 relative to the sensor 100, as long as the sensing part 221 moves within the set range and can keep shielding the light beam of the photoelectric sensor, the sensing signal of the photoelectric sensor remains unchanged; and when the deflection angle of the vertical brush is too large, the sensing part 221 moves relative to the photoelectric sensor beyond the set range, so that the light beam of the photoelectric sensor changes from the shielding state to the unshielding state of the sensing part 221, and the sensing signal of the photoelectric sensor changes, thereby forming a corresponding electrical signal.

[0046] The arrangement of the avoidance portion 226 can avoid the light beam of the photoelectric sensor at the end of the sensing portion 221 connected to the mounting section 210, thereby preventing the sensing portion 221 and the connecting portion 212 of the mounting section 210 from affecting the sensing of the photoelectric sensor. Figure 2 , the avoidance portion 226 can avoid the light beam of the photoelectric sensor on the right side of the sensing portion 221. Therefore, when the vertical brush deflects and causes the sensing member 200 to swing to the left at an excessively large angle, so that the sensing portion 221 moves to the left and exceeds the set range, the avoidance space formed by the avoidance portion 226 is aligned with the light beam of the photoelectric sensor. The light beam of the photoelectric sensor 100 changes the sensing signal due to being out of the shielding of the sensing portion 221. Therefore, referring to Figure 3 The movement of the sensing part 221 toward the front, rear, left, and right directions, or toward any direction between these four directions until the sensing part 221 is out of the way of blocking the light beam of the photoelectric sensor, can change the sensing signal of the photoelectric sensor. Therefore, it is possible to detect whether the deflection angle of the vertical brush in various directions exceeds the preset range, so as to prompt an abnormality.

[0047] refer to Figure 2 and Figure 3 In some embodiments, the avoidance portion 226 is connected between the sensing portion 221 and the mounting section 210, and the avoidance portion 226 is recessed in a direction away from the sensing portion 221 to form an avoidance space between the sensing portion 221 and the mounting section 210. The distance between the avoidance portion 226 and the sensor 100 is greater than the distance between the sensing portion 221 and the sensor 100, thereby being able to avoid the light beam of the photoelectric sensor at a position between the sensing portion 221 and the mounting section 210.

[0048] refer to Figure 2 and Figure 3 In some embodiments, the sensor 100 includes a photoelectric sensor, so that the position of the photoelectric sensor corresponds to the position of the sensing part 221 on the sensing element 200, and the sensing part 221 blocks the light beam of the photoelectric sensor, so that it can be sensed by the photoelectric sensor. When the vertical brush deflects and causes the sensing part 221 to move relative to the sensor 100, as long as the sensing part 221 moves within the set range and can keep blocking the light beam of the photoelectric sensor, the sensing signal of the photoelectric sensor remains unchanged; and when the deflection angle of the vertical brush is too large, the sensing part 221 moves relative to the photoelectric sensor beyond the set range, so that the light beam of the photoelectric sensor changes from the blocked state to the unblocked state of the sensing part 221, and the sensing signal of the photoelectric sensor changes, thereby forming a corresponding electrical signal. In this way, it is possible to detect whether the deflection angle of the vertical brush exceeds the preset range, so as to prompt the abnormality in time.

[0049] Figure 4 is a schematic diagram of a deflection detection module according to another embodiment of the present invention, Figure 5 for Figure 4 Top view of Figure 1 , Figure 4 and Figure 5 In the deflection detection module of other embodiments, the sensor 100 may include two photoelectric sensors, which are arranged side by side and have light beams facing the same side. The sensing portion 221 extends along the arrangement direction of the two photoelectric sensors and can block the light beams of the two photoelectric sensors at the same time. When the sensing portion 221 deviates from the light beam of any photoelectric sensor, the detection signal of the sensor 100 changes, thereby determining whether the deflection angle of the vertical brush in each direction is too large according to the signal changes of the two photoelectric sensors 100. For example, when both photoelectric sensors are blocked by the sensing portion 221, the photoelectric sensors can sense the sensing portion 221, and their sensing states are recorded as 1, indicating that the photoelectric sensors have signals, and the two photoelectric sensors have a sensed state. The combined signal of the sensors is (1, 1), and the deflection angle of the vertical brush is judged to be within the set angle range; when the sensing part 221 deviates from the light beam of any photoelectric sensor, the corresponding photoelectric sensor cannot sense the sensing part 221, and its detection signal changes to 0. Therefore, the combined signal of the two photoelectric sensors is (1, 0) or (0, 1), and the deflection angle of the vertical brush is judged to exceed the set angle range; when the sensing part 221 deviates from the light beam of the two photoelectric sensors, the two photoelectric sensors cannot sense the sensing part 221, and their detection signals change to 0. Therefore, the combined signal of the two photoelectric sensors is (0, 0), and the deflection angle of the vertical brush is judged to exceed the set angle range. It can be understood that the present embodiment can adopt a commonly used controller to communicate with each photoelectric sensor to realize the reception and judgment of the sensing signal.

[0050] The following are some typical examples of detection performed by the deflection detection module according to this embodiment. Figure 4 and Figure 5 , the two photoelectric sensors can be respectively recorded as the left photoelectric sensor 110 and the right photoelectric sensor 120:

[0051] When the vertical brush deflects to the left, the sensing element 200 swings to the right, so that the sensing portion 221 moves to the right and exceeds the set range. At this time, the left edge 222 of the sensing portion 221 is out of the shielding of the left photoelectric sensor 110, so the sensing signal of the left photoelectric sensor 110 changes, thereby determining that the deflection angle of the vertical brush to the left is too large;

[0052] When the vertical brush deflects to the right and causes the sensing element 200 to swing to the left, so that the sensing portion 221 moves to the left and exceeds the set range, the avoidance space formed by the avoidance portion 226 is aligned with the light beam of the right photoelectric sensor 120, and the right edge 223 of the sensing portion 221 is free from blocking the light beam of the right photoelectric sensor 120, and the sensing signal of the light beam of the right photoelectric sensor 100 changes, thereby determining that the deflection angle of the vertical brush to the right is too large;

[0053] When the vertical brush deflects forward and causes the sensing member 200 to swing backward, so that the sensing portion 221 moves backward and exceeds the set range, at this time, the front edge 224 of the sensing portion 221 is free from the shielding of the two photoelectric sensors, so the sensing signals of the two photoelectric sensors change, thereby determining that the vertical brush has deflected forward too much.

[0054] When the vertical brush deflects backwards and causes the sensing element 200 to swing forward, so that the sensing portion 221 moves forward and exceeds the set range, the rear edge 225 of the sensing portion 221 is free from the obstruction of the two photoelectric sensors, so the sensing signals of the two photoelectric sensors change, thereby determining that the deflection angle of the vertical brush backwards is too large.

[0055] refer to Figure 6 and Figure 7 In the above-mentioned deflection detection module with two photoelectric sensors, two mounting plates 300 are also included. The two photoelectric sensors are respectively connected to the two mounting plates 300. The mounting plates 300 are used for fixing the photoelectric sensors. For example, the mounting plates 300 can be connected to a bracket 500 for mounting a vertical brush. The distance between the two mounting plates 300 is adjustable. Figure 7 , the two mounting pieces 300 are provided with strip holes 310, the strip holes 310 extend in the arrangement direction of the two photoelectric sensors, the mounting pieces 300 can be mounted on the bracket 500 by means of fasteners (such as screws), and the spacing between the two mounting pieces 300 can be adjusted by adjusting the position of the fasteners in the strip holes 310, thereby adjusting the spacing between the two photoelectric sensors, thereby adjusting the range in which the sensing part 221 of the sensing element 200 can move in the left and right directions relative to the two photoelectric sensors. For example, by reducing the spacing between the two photoelectric sensors, the sensing part 221 can move a greater distance in the left and right directions to escape from the obstruction of the light beam, so the range in which the sensing part 221 can move in the left and right directions relative to the two photoelectric sensors becomes larger, thereby increasing the detection range of the deflection angle of the vertical brush in the left and right directions; conversely, by increasing the spacing between the two photoelectric sensors, the range in which the sensing part 221 can move in the left and right directions relative to the two photoelectric sensors becomes smaller, thereby reducing the detection range of the deflection angle of the vertical brush in the left and right directions. Therefore, by adjusting the spacing of the mounting plates 300 , the deflection detection module can have a certain degree of adaptability so as to meet the detection requirements of different deflection angle ranges.

[0056] It should be noted that the above-mentioned left and right directions are only reference directions in some examples and do not represent absolute directions. For example, in some embodiments, the setting directions of the sensing section 220 and the mounting section 210 of the sensing element 200 can also be reversed to achieve the above-mentioned beneficial effects.

[0057] Figure 8 for Figure 6 Side view of Figures 6 to 8 In the deflection detection module of some embodiments, the mounting plate 300 includes a first connection surface 320 and a second connection surface 330. The first connection surface 320 is used to connect the bracket 500 on which the vertical brush is installed. The second connection surface 330 is tilted at a set angle relative to the first connection surface 320 to form a second connection surface 330 tilted from top to bottom in a direction away from the bracket 500. The photoelectric sensor is connected to the second connection surface 330, thereby forming an inclined photoelectric sensor. Therefore, it is possible to provide a suitable activity space for the offset movement of the sensing part 221 on the side of the photoelectric sensor facing the bracket 500. The sensing part 221 is parallel to the second connection surface 330, so that it can block the light beam of the inclined photoelectric sensor.

[0058] refer to Figures 1 to 7 In the deflection detection module of the above embodiment, the mounting section 210 includes a mounting portion 211 and a connecting portion 212. The mounting portion 211 is used to connect the vertical brush. The connecting portion 212 extends toward the side of the mounting portion 211 away from the vertical brush. The avoidance portion 226 is connected between the sensing portion 221 and the connecting portion 212. Thus, the connecting portion 212 extends the space between the mounting portion 211 and the sensing portion 221, which can realize the connection of the vertical brush and the effective avoidance of other structural parts. The mounting portion 211 can be connected to the vertical brush in a direct connection manner, or it can be connected to the vertical brush in an indirect manner according to actual installation requirements, so that the sensing member 200 can swing with the deflection of the vertical brush. Among them, the mounting portion 211, the avoidance portion 226 and the sensing portion 221 can be located on the same side of the connecting portion 212, and the sensor 100 is located between the mounting portion 211 and the sensing portion 221, forming a compact structure, which can be suitable for situations where the activity space is narrow.

[0059] In the deflection detection module of some embodiments, the sensing element 200 is made of a sheet material into an integrated structure, and the above-mentioned sensing part 221, avoidance part 226, connecting part 212 and installation part 211, etc. can be formed by conventional punching, bending and other processing methods. The molding method is simple and easy to implement. The integrated structure can simplify the assembly process and is easier to assemble.

[0060] refer to Figure 1 as well as Figures 6 to 8According to a second aspect of the present invention, there is provided a vertical brush device, comprising a bracket 500, a vertical brush mechanism 400 and a deflection detection module of the first aspect of the present invention. The vertical brush mechanism 400 comprises a vertical brush (omitted in the figure) and a vertical brush driving assembly 420, wherein the vertical brush is rotatably connected to the bracket 500, and the vertical brush driving assembly 420 is connected to the bracket 500 and is used to drive the vertical brush to rotate around the central axis 410. The sensor 100 in the deflection detection module is connected to the bracket 500, and the sensor 100 can be connected to the bracket 500 through the mounting piece 300. The sensing member 200 is connected to the central axis 410 of the vertical brush through the mounting section 210, and the sensing member 200 can swing with the deflection of the vertical brush. Therefore, when washing a car, the vertical brush can be appropriately deflected according to the surface to be brushed. As can be seen from the above, the deflection detection module can sense the deflection angles of the vertical brush in various directions.

[0061] In some vertical brush devices, the vertical brush is normally extended in the vertical direction, that is, the central axis 410 of the vertical brush is extended in the vertical direction. In order to ensure that the vertical brush has a certain brushing force, an elastic member 431 can be provided to provide elastic force to ensure that the vertical brush is kept close to the surface of the car during the brushing process. Compared with the solution of fixed vertical brush arrangement, it has better adaptability and plays a buffering role for the connection structure of the vertical brush. When working, the vertical brush mounted on the bracket 500 in a deflectable manner will deflect accordingly due to the change of the curved surface of the car surface being brushed. When the position of the vertical brush is abnormal, for example, when the distance between the central axis 410 of the vertical brush and the surface to be brushed is too small, the convex curved surface of the car surface pushes the vertical brush to deflect to avoid damaging the surface, but the position of the vertical brush is abnormal, resulting in poor brushing effect on the car surface; and when the distance is too large, the brushing force of the vertical brush is insufficient or the vertical brush does not brush the surface of the car, so it is difficult to ensure the cleaning effect of the car washing machine, and it is often necessary to re-clean, which affects the cleaning efficiency.

[0062] With the vertical brush device of the embodiment of the present invention, when the deflection angle of the vertical brush is too large, the sensing signal of the sensor 100 changes, thereby indicating an abnormality, so that the vertical brush can be repaired or the angle of the vertical brush can be adjusted in time to ensure the cleaning effect.

[0063] Since the upper part of a car is usually smaller than the lower part, and the side surface of the car is non-planar, the vertical brush device of some embodiments of the present invention also includes a deflection assembly 430. The deflection assembly 430 includes an elastic member 431 and a mounting member 432. The elastic member 431 is connected to the bracket 500, the mounting member 432 is connected to the elastic member 431, and the vertical brush is connected to the mounting member 432. The elastic force of the elastic member 431 can deflect the vertical brush to a set angle relative to the vertical direction under normal conditions, thereby ensuring that the vertical brush has a certain brushing force during brushing, so that the vertical brush can remain close to the side surface of the car, so that the vertical brush can have a suitable brushing force relative to the car surface. For example, refer to Figure 6, the angle of deflection of the vertical brush relative to the vertical direction is represented by β. Under normal conditions, the vertical brush is deflected at a set angle β relative to the vertical direction so that the bottom of the vertical brush is away from the surface of the car and the top is close to the surface of the car, which can be suitable for brushing the side surface of the side of the car. When washing the car, if the deflection angle β of the vertical brush is too small, the distance between the vertical brush and the upper half of the side surface of the car is too large, then the brushing force is too small or the upper half of the side surface cannot be brushed, resulting in a poor cleaning effect. If the deflection angle β of the vertical brush is too large, the distance between the vertical brush and the lower half of the side surface of the car is too large, then the brushing force is insufficient or the lower half of the side surface cannot be brushed, resulting in a poor cleaning effect. Therefore, the vertical brush device of the embodiment of the present invention adopts the deflection detection module of the first embodiment described above, which can detect whether the deflection angle β of the vertical brush is within the set range, thereby facilitating timely maintenance or adjustment of the position or angle of the vertical brush device, ensuring the cleaning effect, and improving the efficiency of car washing.

[0064] Among them, reference Figure 6 and Figure 7 The elastic member 431 can adopt a bell-shaped shock absorber commonly used in the art, the mounting member 432 is connected to the central axis 433 of the bell-shaped shock absorber, and the sensing member 200 can be connected to the central axis 433 of the bell-shaped shock absorber. Thus, the deflection of the vertical brush causes the mounting member 432 to deflect, thereby driving the central axis 433 of the bell-shaped shock absorber to deflect accordingly, thereby causing the sensing member 200 to swing accordingly.

[0065] Specifically, taking the embodiment with two photoelectric sensors as an example, refer to Figure 6 and Figure 7The vertical brush device includes the above-mentioned deflection detection module with two photoelectric sensors arranged side by side. Under normal conditions, the vertical brush deflects to the right by a set angle. At this time, the sensing part 221 blocks the light beams of the two photoelectric sensors, and the sensing signals of the two photoelectric sensors 100 are recorded as (1, 1); when the deflection angle β of the vertical brush is too small, the sensing part 221 moves to the left relative to the photoelectric sensor, and the left edge 222 of the sensing part 221 is out of the blocking of the light beam of the left photoelectric sensor 110, so that the left photoelectric sensor 110 does not detect the sensing signal. When the deflection angle β of the vertical brush is too large, the sensing part 221 moves rightward relative to the sensor 100, and the right edge 223 of the sensing part 221 is out of the way of blocking the light beam of the right photoelectric sensor 120 (the avoidance part 226 corresponds to the right photoelectric sensor 120), so that the right photoelectric sensor 120 does not detect the sensing part 221 and the sensing signal becomes 0, and the sensing signals of the two photoelectric sensors 100 are recorded as (1, 0). In this way, it is possible to detect whether the vertical brush is within the appropriate deflection angle range, so as to perform brushing of the side surface of the car. During the scrubbing process, if the vertical brush is within the set angle range, the sensing signals of the two photoelectric sensors remain unchanged at (1, 1); if the deflection angle β of the vertical brush exceeds the set angle range, one or both of the sensing signals of the two photoelectric sensors change, thereby providing an abnormal prompt so that the deflection angle of the vertical brush can be adjusted in time to obtain a better scrubbing effect, thereby improving the efficiency of car washing.

[0066] It should be noted that the above-mentioned left and right directions are only reference directions in some examples and do not represent absolute directions. For example, in some embodiments, the deflection direction of the vertical brush, the extension direction of the sensing part 221, etc. can also be reversed to achieve the above-mentioned beneficial effects.

The vertical brush devices are mounted on the frame 600 through brackets 500. It can be seen from the above that the vertical brush devices of the above embodiments can ensure that the car washing machine has a better brushing effect, thereby improving the car washing efficiency.
