Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a direction detection component, a body, a cleaning device, and a cleaning system. Background Technology

[0002] One type of floor scrubber on the market with two assist wheels maintains the same rotation speed during turning. This results in a smaller turning angle and a larger turning radius, making the scrubber less maneuverable.

[0003] To address this, a technology referencing the principle of automotive differentials exists. This technology considers controlling the speed difference between the assist wheels by detecting the rotation direction of the machine's shaft when the floor scrubber turns, achieving a lower speed for the inner wheel and a higher speed for the outer wheel. This helps ensure the floor scrubber can turn more easily and improves cleaning efficiency in low-ceilinged spaces such as under sofas and beds, ultimately enhancing the user experience. However, current technology struggles to accurately determine the turning angle of the floor scrubber, and therefore cannot accurately adjust the speed difference between the assist wheels to achieve steering. How to detect the rotation direction of the machine's shaft more promptly and accurately is a problem that urgently needs to be solved. Utility Model Content

[0004] The main purpose of this invention is to propose a direction detection component, a body, a cleaning device, and a cleaning system, aiming to provide a new solution that can flexibly and accurately sense the rotation direction of the body shaft.

[0019] The resistive element includes a first resistive segment, an intermediate resistive segment, and a second resistive segment arranged sequentially along its length.

[0020] The adjusting member is connected to the intermediate resistance section, and during the forward adjustment stroke, the adjusting member is driven to move away from the intermediate resistance section to the first resistance section; and during the reverse adjustment stroke, the adjusting member is driven to move away from the intermediate resistance section to the second resistance section.

[0021] Optionally, when the adjusting member is connected to the intermediate resistance segment, the first resistance segment and the second resistance segment respectively, the resistance value of the resistor connected to the circuit body is adjusted to the initial resistance value, the first resistance value and the second resistance value respectively.

[0022] The first resistance value is greater than the initial resistance value, and the second resistance value is less than the initial resistance value.

[0023] Optionally, during the forward adjustment stroke, the first resistance value is set to gradually increase; and / or,

[0024] During the reverse adjustment stroke, the second resistance value is set to gradually decrease; and / or,

[0026] Optionally, as the adjusting member moves along the intermediate resistance segment toward the first resistance segment, the initial resistance value is gradually increased; and / or,

[0027] As the adjusting member moves along the intermediate resistance segment toward the direction closer to the second resistance segment, the initial resistance value is gradually decreased; and / or,

[0028] The length of the first resistor segment is greater than the length of the intermediate resistor segment; and / or,

[0030] Optionally, the circuit body includes a signal input section for inputting electrical signals and a signal output section for outputting electrical signals;

[0031] The signal input segment and the signal output segment are respectively connected at opposite ends of the resistor along its length; or,

[0043] In the technical solution provided by this utility model, when an external force drives the rotating main body and the mating main body to rotate relative to each other, the adjusting component and the resistive component are simultaneously driven to adjust their relative strokes. At this time, under the adjustment of the adjusting component, the resistance value of the resistive component connected to the circuit main body changes, which in turn causes a change in the overall output electrical signal of the circuit main body. The user can automatically correlate the rotation direction of the rotating main body with the monitored changes in the output electrical signal of the circuit main body. This facilitates the specific adjustment of the speed difference required for the two assist wheels to reach a target, based on the rotation direction of the rotating main body. Ultimately, this helps to increase the turning flexibility of the entire machine and improve its overall reliability. Attached Figure Description

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0057] Please see Figures 1 to 6 This utility model provides a direction detection component 100. The direction detection component 100 can be manufactured and applied independently as a standalone module. Alternatively, the direction detection component 100 can be integrated into any type of machine body. Alternatively, the direction detection component 100 can be directly or indirectly integrated into cleaning equipment via the aforementioned machine body.

[0058] First, it should be noted that, for ease of understanding, the following embodiments will be described using the example of the direction detection component 100, the main body, and the cleaning device having approximately perpendicular vertical, horizontal, and longitudinal directions. In practical applications, the vertical direction roughly corresponds to the direction of gravity, with opposite directions of upward and downward. The longitudinal direction roughly corresponds to the walking direction of the cleaning device in a non-turning state, with opposite directions of forward and backward.

[0059] It is understood that the body generally also includes a rotating main body 200a and a mating main body 300a. The rotating main body 200a and the mating main body 300a can rotate relative to each other under the drive of an external force. Specifically, one of the rotating main body 200a and the mating main body 300a may be subjected to force and rotate, while the other remains relatively stationary. Alternatively, both the rotating main body 200a and the mating main body 300a may be subjected to force and rotate. Furthermore, the rotational states of the rotating main body 200a and the mating main body 300a are different. The rotational state may be, but is not limited to, rotational speed and / or rotational direction. However, for ease of understanding, in the following embodiments, the example will be that the rotating main body 200a is subjected to force and rotates, while the mating main body 300a is approximately stationary.

[0060] Furthermore, the direction of relative rotation between the rotating body 200a and the mating body 300a is not limited. However, for ease of understanding, in the following embodiments, the rotating body 200a is rotatably mounted on the mating body 300a about an axis extending vertically.

[0061] Cleaning equipment typically includes a body module 200 and a base module 300. Taking a handheld floor scrubber as an example: the body module 200 is generally designed as a long, vertically extending rod. Depending on the specific needs, the body module 200 may include the rod body, and components such as a motor and battery housed within it. The base module 300 is generally located vertically below the body module 200. The base module 300 typically includes a base 310, two auxiliary wheels 320 rotatably connected to the horizontal sides of the base 310, and a drive mechanism. The drive mechanism can drive the two auxiliary wheels 320 to rotate relative to the base 310, thereby enabling the entire machine to move in a straight line or turn.

[0062] In practical applications, a single drive mechanism can drive both assist wheels 320 to rotate. In this case, the drive mechanism typically includes a driver and two transmission components. The driver is, for example, a motor. The power input ends of both transmission components are connected to the driver. The power output ends of the two transmission components are connected one-to-one to the two assist wheels 320. Thus, by differentiating the two transmission components, independent control and adjustment of, for example, the speed of the two assist wheels 320 can be achieved.

[0063] Alternatively, in practical applications, two drive mechanisms can be configured, each corresponding to one of the two assist wheels 320. In this case, each drive mechanism can be directly composed of a driver, such as a motor. The two motors independently drive the two assist wheels 320, enabling independent control and adjustment of, for example, the speed of the two assist wheels 320. Alternatively, each drive mechanism can also include at least one driver and a transmission component as described above.

[0064] When the machine body is used in a cleaning device, for example, the rod in the body module 200 can directly form the rotating body 200a. That is, the rod and the rotating body 200a can be integrally formed. Alternatively, the rod and the rotating body 200a in the body module 200 can be separately formed and then connected in a detachable or non-detachable manner.

[0065] Similarly, the base 310 in the base module 300 can directly form the mating body 300a. That is, the base 310 and the mating body 300a can be integrally formed. Alternatively, the base 310 and the mating body 300a in the base module 300 can be detachably or non-detachably connected after being separately formed.

[0066] Since the main improvement of this utility model is the direction detection component 100, based on one or more of the above embodiments, the following will be combined with... Figures 1 to 6 This section mainly elaborates on the specific structure of the orientation detection component 100.

[0067] The orientation detection assembly 100 includes a circuit body 110, an adjustment element 120, and a resistor element 130. One of the adjustment element 120 and the resistor element 130 is disposed on the rotating body 200a, and the other is disposed on the mating body 300a.

[0068] The rotating body 200a and the mating body 300a are rotatably arranged to drive the adjusting member 120 and the resistive member 130 to have a relative adjustment stroke. During the relative adjustment stroke, the adjusting member 120 is used to adjust the resistance value of the resistive member 130 connected to the circuit body 110. The circuit body 110 is used to output a corresponding electrical signal according to the resistance value. This electrical signal corresponds to the rotation direction of the rotating body 200a.

[0069] In the technical solution provided by this utility model, when an external force drives the rotating body 200a and the mating body 300a to rotate relative to each other, the adjusting member 120 and the resistive member 130 are simultaneously driven to adjust their relative strokes. That is, the adjusting movement of the adjusting member 120 relative to the resistive member 130 is synchronized with the rotational movement of the rotating body 200a relative to the mating body 300a. This establishes a strict correlation between the stroke of the adjusting movement and the stroke of the rotational movement. Furthermore, the stroke of the adjusting member 120 relative to the resistive member 130 can be largely determined by the resistance value of the resistive member 130 connected to the circuit body 110.

[0070] It can then be understood that regardless of how the adjusting member 120 is adjusted, it at least connects the resistor 130 to the same circuit body 110. Therefore, by pre-associating the resistance value formed by connecting the resistor 130 to the circuit body 110 with the final output electrical signal generated by the circuit body 110, it can be ensured that when a specific output electrical signal is received, the resistance value of the corresponding resistor 130 connected to the circuit body 110 and the amount of travel of the adjusting member 120 relative to the resistor 130 are determined accordingly, ultimately allowing the amount of travel of the corresponding rotating body 200a relative to the mating body 300a to be uniquely determined.

[0071] The stroke amount can be specifically set as a vector, that is, it has both magnitude and direction. This allows the rotation direction of the rotating body 200a relative to the mating body 300a to be accurately detected, achieving the ultimate goal of this design.

[0072] When the rotation direction of the rotating main body 200a relative to the mating main body 300a is accurately detected, it facilitates subsequent adjustments to the speed difference between the two auxiliary wheels 320 to achieve the target, based on the rotation direction of the rotating main body 200a. This helps to increase the turning angle and reduce the turning radius of the machine. Ultimately, this contributes to increasing the turning flexibility and improving the overall reliability of the machine.

[0073] It is understandable that the rotation direction of the rotating body 200a relative to the mating body 300a is generally divided into forward rotation (e.g., clockwise rotation) and reverse rotation (e.g., counterclockwise rotation).

[0074] In order to be able to deduce whether the rotating body 200a is rotating in the forward or reverse direction relative to the mating body 300a by using different output electrical signals from the main circuit 110, in practical applications, the following settings can be configured:

[0075] When the rotating body 200a rotates forward relative to the mating body 300a, it drives the adjusting member 120 and the resistive member 130 to form a forward adjustment stroke. During the forward adjustment stroke, the adjusting member 120 can adjust the resistance value of the resistive member 130 connected to the circuit body 110 to a first resistance value. Correspondingly, the output electrical signal of the circuit body 110 is a first output signal.

[0076] Conversely, when the rotating body 200a rotates in the opposite direction to the mating body 300a, it can drive the adjusting member 120 and the resistive member 130 to form a reverse adjustment stroke. During the reverse adjustment stroke, the adjusting member 120 can adjust the resistance value of the resistive member 130 connected to the circuit body 110 to a second resistance value. Correspondingly, the output electrical signal of the circuit body 110 is a second output signal.

[0077] The first resistor value and the second resistor value are set to be different. Furthermore, the first output signal and the second output signal are set to be different.

[0078] Based on the above, during the entire process of the rotating body 200a rotating forward relative to the mating body 300a, the resistance value of the adjusting element 120 and the resistor element 130 connected to the circuit body 110 can be set to remain constant, being the same first resistance value. Correspondingly, the output electrical signal of the circuit body 110 remains constant, being the same first output signal. Conversely, during the entire process of the rotating body 200a rotating backward relative to the mating body 300a, the resistance value of the adjusting element 120 and the resistor element 130 connected to the circuit body 110 can be set to remain constant, being the same second resistance value. Correspondingly, the output electrical signal of the circuit body 110 remains constant, being the same second output signal.

[0079] In this way, the detection data and the entire detection process involved in the orientation detection component 100 can be made simpler and more targeted.

[0080] Alternatively, during the entire process of the rotating body 200a rotating forward relative to the mating body 300a, the resistance value of the adjusting element 120 connected to the circuit body 110 can be adjusted to vary accordingly, resulting in multiple different first resistance values. Each first resistance value does not exceed a first resistance range. Correspondingly, the output electrical signal of the circuit body 110 changes accordingly, resulting in different first output signals. Each first output signal does not exceed a first output range. Conversely, during the entire process of the rotating body 200a rotating backward relative to the mating body 300a, the resistance value of the adjusting element 120 connected to the circuit body 110 can be adjusted to vary accordingly, resulting in multiple different second resistance values. Each second resistance value does not exceed a second resistance range. Correspondingly, the output electrical signal of the circuit body 110 changes accordingly, resulting in different second output signals. Each second output signal does not exceed a second output range.

[0081] The first and second resistance ranges mentioned above are set to have virtually no overlap. Similarly, the first and second output ranges are set to have virtually no overlap. This ensures that, based on the different output electrical signals, it can be uniquely and accurately detected whether the rotating body 200a is rotating in the forward or reverse direction.

[0082] Of course, taking the first resistance value, first resistance range, first output signal, and first output range as an example, further, each first resistance value within the first resistance range is set differently. Each first output signal within the first output range is set differently. Furthermore, each first output signal and each first resistance value are mapped one-to-one. This ensures that when the rotating body 200a rotates forward relative to the mating body 300a, and rotates to different first and second angles, the first resistance value and first output signal corresponding to the first angle will necessarily be different from those corresponding to the second angle. Therefore, based on the first output signal, it can be determined not only whether the rotating body 200a is rotating forward or backward relative to the mating body 300a, but also the specific rotation angle of the rotating body 200a relative to the mating body 300a. By reasonably utilizing this specific rotation angle, the rotational state of the two assist wheels 320 can be controlled. For example, when the specific rotation angle is large, it is possible to consider appropriately reducing the rotational speed of each assist wheel 320 while controlling the speed difference between the two assist wheels 320. No restrictions are imposed.

[0083] After the adjusting element 120 achieves a relative adjustment stroke with the resistive element 130 as described above, there are several ways to achieve different purposes by adjusting the resistance value of the resistive element 130 connected to the circuit body 110:

[0084] In one application, resistor 130 may include multiple individual resistors. Each individual resistor has a different resistance value. One end of each individual resistor is connected in parallel to a section of circuit body 110. The other end of each individual resistor is left unconnected. At this time, adjustment element 120 can be connected in series to another section of circuit body 110. During relative adjustment, adjustment element 120 is driven to connect sequentially to the unconnected end of different individual resistors, so that the individual resistor can be connected in series to circuit body 110.

[0085] Or such as Figures 3 to 6 In the structure shown, the resistance value of the resistor 130 is positively correlated with its length. That is, the longer the resistor 130 is connected to the circuit body 110, the greater the resistance value it forms in the circuit body 110. Conversely, the shorter the length of the resistor 130 connected to the circuit body 110, the smaller the resistance value it forms in the circuit body 110.

[0086] At this time, the adjusting member 120 overlaps with the resistive member 130. The adjusting member 120 can be moved along the resistive member 130 during relative adjustment strokes. The overlap of the adjusting member 120 divides the resistive member 130 into an effective resistance segment connected in series with the circuit body 110, and a remaining ineffective resistance segment not connected in series with the circuit body 110. As the adjusting member 120 moves, the length of the effective resistance segment changes, and the resistance value formed in the circuit body 110 also changes. The adjusting member 120, the effective resistance segment, and the circuit body 110 together constitute a complete and effective detection circuit.

[0087] The resistance value of the resistor 130 can be set in a discrete positive correlation with its length. That is, the effective and ineffective resistance segments can be defined only when the adjusting member 120 travels along the resistor 130 to several predetermined target positions, thereby achieving the aforementioned detection objective. At this time, the adjustment of the resistance value of the resistor 130 connected to the circuit body 110 by the adjusting member 120 is equivalent to stepped adjustment.

[0088] Alternatively, the resistance value of resistor 130 can be set in a continuous positive correlation with its length. That is, as long as the adjusting member 120 and resistor 130 are connected, the effective resistance segment and the ineffective resistance segment can be directly defined. As the adjusting member 120 is continuously moved along resistor 130, the length of the effective resistance segment continuously increases or decreases. The resistance value formed by the effective resistance segment in the circuit body 110 also continuously increases or decreases. At this time, the adjustment of the resistance value of resistor 130 connected to the circuit body 110 by the adjusting member 120 is equivalent to stepless adjustment.

[0089] It should be noted that when the adjusting member 120 moves along the resistive member 130, the trajectory of the adjusting member 120 can be related to the shape of the resistive member 130. Alternatively, depending on actual needs, the trajectory of the adjusting member 120 can be independent of the shape of the resistive member 130. For example, when the trajectory of the adjusting member 120 is straight, the resistive member 130 can be set as a corresponding elongated structure. Alternatively, the resistive member 130 can be set as having sufficient space to cover the straight trajectory, such as a circle, polygon, or irregular shape. However, for ease of understanding, in the following embodiments, the example of the resistive member 130's shape being adapted to the trajectory of the adjusting member 120 will be used for illustration.

[0090] In a specific application, the resistor 130 is adapted to extend in an arc shape along the circumferential direction of the rotating body 200a and the mating body 300a. The travel trajectory of the adjusting member 120 along the resistor 130 is also arc-shaped. The center of this arc-shaped travel trajectory can fall on the rotation axis of the rotating body 200a. Thus, during assembly, it is only necessary to fix the adjusting member 120 to, for example, the rotating body 200a, and the resistor 130 to, for example, the mating body 300a. This helps to make the assembly of the adjusting member 120 and the resistor 130 as simple and convenient as possible. Furthermore, the rotational motion of the rotating body 200a relative to the mating body 300a can be directly converted into the rotational adjustment motion of the adjusting member 120 relative to the resistor 130, with virtually no motion transmission loss.

[0091] The arc-shaped extension of the resistor 130 described above can specifically be an extension in a complete ring shape along the entire circumference of the rotating body 200a. That is, the arc center angle of the resistor 130 ranges from 0° to 360°. In this way, the adjustment range of the adjusting member 120 for the resistor 130 can be made larger.

[0092] In practical applications, the body module 200 and the base module 300 generally do not require 360° rotation. Therefore, the arc-shaped extension of the resistor 130 described above can specifically be a notched annular extension along the circumference of the rotating body 200a. That is, the arc angle of the resistor 130 ranges from 0° to a value less than 360°. This makes the adjustment range of the resistor 130 by the adjusting member 120 more suitable for practical applications. Furthermore, it helps to simplify the structure of the adjusting member 120 and the resistor 130. More specifically, the arc angle range of the resistor 130 can be specifically set to be not less than 60° and not more than 150°.

[0093] Of course, besides the aforementioned arc-shaped extension arrangement, in other applications, the resistor 130 can also be adapted to extend linearly in the circumferential direction of the rotating body 200a and the mating body 300a. In this case, in order to convert the rotational motion of the rotating body 200a relative to the mating body 300a into the linear motion of the adjusting member 120 (specifically, the overlapping part of the adjusting member 120 to the resistor 130) relative to the resistor 130, after assembling the adjusting member 120 to, for example, the rotating body 200a and the resistor 130 to the mating body 300a, it can be further configured that the adjusting member 120 and the resistor 130 have translational degrees of freedom in the rotational radial direction of the rotating body 200a and the mating body 300a, allowing them to move closer to each other and further away from each other.

[0094] Specifically, for example, the adjusting member 120 is extendable and retractable in the rotational radial direction of the rotating body 200a and the mating body 300a. In a specific structure, the adjusting member 120 may include a mounting section, a telescopic section, and an overlapping section. The mounting section is fixedly mounted to the rotating body 200a or the mating body 300a. The telescopic section is extendable and retractable in the rotational radial direction of the rotating body 200a and the mating body 300a. The overlapping section overlaps with the resistor 130 and travels along the resistor 130.

[0095] The expansion and contraction of the telescopic segment can be a contractile deformation activity. In this case, the telescopic segment can be made of, for example, a material with variable elasticity. It can undergo elongation and shortening deformation. Alternatively, the expansion and contraction of the telescopic segment can be a translational activity between rigid structures. In this case, the telescopic segment can be composed of multiple telescopic joints that are sequentially and movably connected. Each pair of adjacent telescopic joints has a retracted state that folds together and an unfolded state that unfolds together.

[0096] When the resistor 130 is elongated as described above, it is designed to better accommodate the forward and reverse adjustment strokes of the adjustment member 120. Specifically, the resistor 130 may be configured to include a first resistor segment 131, an intermediate resistor segment 132, and a second resistor segment 133 arranged sequentially along its length.

[0097] In the initial state, the rotating body 200a does not need to rotate relative to the mating body 300a; the rotation of the assist wheel 320 can drive the entire machine to move forward and backward in a straight line. At this time, the adjusting member 120 can be directly connected to the intermediate resistance section 132. Correspondingly, the adjusting member 120 currently adjusts the resistance value of the resistor 130 connected to the circuit body 110 to the initial resistance value.

[0098] During the forward adjustment stroke, that is, when the rotating body 200a rotates forward relative to the mating body 300a, the adjusting member 120 is driven to move along the first resistance segment 131. Specifically, the adjusting member 120 moves in a direction away from the intermediate resistance segment 132 (for ease of understanding, this direction is defined hereinafter as the first direction D1). Correspondingly, the adjusting member 120 currently adjusts the resistance value of the resistor 130 connected to the circuit body 110 to the first resistance value as described above. The first resistance group is within, for example, the first resistance range described above.

[0099] During the reverse adjustment stroke, the adjusting member 120 is driven to move along the second resistance segment 133. Specifically, the adjusting member 120 moves in a direction away from the intermediate resistance segment 132 (for ease of understanding, this direction is hereinafter defined as the second direction D2). Correspondingly, the adjusting member 120 currently adjusts the resistance value of the resistor 130 connected to the circuit body 110 to the second resistance value as described above. The second resistance group is within the aforementioned, for example, second resistance range.

[0100] Understandably, the initial resistance value, the first resistance value, and the second resistance value need to be set differently. However, in practical applications, these three values ​​can be set in any manner that suggests a difference. That is, there is no restriction on the relative magnitudes of the initial, first, and second resistance values. For example, when the initial resistance value is set between the first and second resistance values, the first resistance value can be set to be greater than the second resistance value. Alternatively, the first resistance value can also be set to be less than the second resistance value.

[0101] As described above, when the adjusting member 120 and the resistive member 130 are in the forward adjustment stroke, the resistance value of the resistive member 130 connected to the circuit body 110 can be multiple different first resistance values. Furthermore, it can be set that as the adjusting member 120 moves along the first direction D1 through the first resistance segment 131, each first resistance value can gradually increase. This ensures that, on the one hand, the first resistance values ​​formed as the adjusting member 120 moves along the first direction D1 through the first resistance segment 131 are different and highly regular, making detection easier. On the other hand, it allows for quick confirmation that the rotating body 200a is rotating forward relative to the mating body 300a by detecting the change in any two first resistance values. Furthermore, the rotation angle variable between the two can be calculated according to actual needs.

[0102] Conversely, when the adjusting member 120 and the resistive member 130 adjust in opposite directions, the resistance value of the resistive member 130 connected to the circuit body 110 can be multiple different second resistance values. Furthermore, it can be set that as the adjusting member 120 moves along the second direction D2 through the second resistance segment 133, each second resistance value gradually decreases. This ensures that, on the one hand, the resulting second resistance values ​​are different and highly regular as the adjusting member 120 moves along the second direction D2 through the second resistance segment 133, making detection easier. On the other hand, by detecting the change in any two second resistance values, it can be quickly determined that the rotating body 200a is rotating in the forward direction relative to the mating body 300a. The rotation angle variable between the two can also be calculated according to actual needs.

[0103] Furthermore, the first resistance values ​​increase sequentially along the first direction D1, and the second resistance values ​​decrease sequentially along the second direction D2, which helps to fully distinguish the detection data of forward rotation and reverse rotation, and avoids the situation where the detection data of the two are too close, which may easily lead to detection errors.

[0104] Next, regarding the setting of the initial resistance value:

[0105] In one application, as the adjusting element 120 travels along the intermediate resistance segment 132, the initial resistance value can be set to remain constant. Thus, the current position of the adjusting element 120 within the intermediate resistance segment 132 can be determined using a single initial resistance value.

[0106] Alternatively, in another application, the initial resistance value can be varied as the adjusting member 120 travels along the intermediate resistance segment 132. Specifically, the initial resistance value gradually increases as the adjusting member 120 travels along the first direction D1 in the intermediate resistance segment 132. And / or, the initial resistance value gradually decreases as the adjusting member 120 travels along the second direction D2 in the intermediate resistance segment 132. This allows for a sufficient range of deviation, which helps simplify the molding of the intermediate resistance segment 132 of the resistor 130.

[0107] When the adjusting element 120 travels through the intermediate resistance section 132, and the initial resistance value changes, forming multiple different initial resistance values, each initial resistance value can fall within the initial resistance range. At this time, the initial resistance range does not overlap with the aforementioned first and second resistance ranges. That is, any value within the initial resistance range, any value within the first resistance range, and any value within the second resistance range are all different. This effectively ensures that when the resistor 130 connected to the circuit body 110 is within the initial resistance range, the two assist wheels 320 do not need to rotate differentially.

[0108] In practical applications, the length of the first resistance segment 131 is greater than the length of the intermediate resistance segment 132. And / or, the length of the second resistance segment 133 is greater than the length of the intermediate resistance segment 132. In this way, the first resistance range and / or the second resistance range can be made larger than the initial resistance range, which helps to detect the forward and reverse rotation of the rotating body 200a more accurately and efficiently.

[0109] It should be noted that when the adjusting member 120 connects the resistor 130 to the circuit body 110 and defines an effective resistance segment and an ineffective resistance segment within the resistor 130, the division of the effective and ineffective resistance segments is not affected by the aforementioned intermediate resistance segment 132, first resistance segment 131, and second resistance segment 133. That is, in practical applications, taking the effective resistance segment as an example, the effective resistance segment can be composed of a portion of the first resistance segment 131 or the second resistance segment 133. Alternatively, the effective resistance segment can be composed of the first resistance segment 131 and a portion of the intermediate resistance segment 132. Alternatively, the effective resistance segment can be composed of the second resistance segment 133 and a portion of the intermediate resistance segment 132. Alternatively, the effective resistance segment can be composed of the first resistance segment 131, the intermediate resistance segment 132, and a portion of the second resistance segment 133. Alternatively, the effective resistance segment can be composed of a portion of the first resistance segment 131, the intermediate resistance segment 132, and the second resistance segment 133. No restrictions are imposed.

[0110] Furthermore, the aforementioned division of the intermediate resistance segment 132, the first resistance segment 131, and the second resistance segment 133 is not limited to being reflected in the visual structure of the resistor element 130. That is, for example, the intermediate resistance segment 132, the first resistance segment 131, and the second resistance segment 133 can be defined by any form of visual identifier. Visual identifiers include, but are not limited to, color, shape, size, and icons. Alternatively, the intermediate resistance segment 132, the first resistance segment 131, and the second resistance segment 133 can be directly integrally formed and cannot be clearly distinguished from the appearance.

[0111] Based on one or more embodiments of the adjusting element 120 and the resistive element 130 described above, the circuit body 110 can further be mainly composed of several wires and at least one electrical component provided according to actual needs. The circuit body 110 includes at least a signal input section 111 for inputting electrical signals and a signal output section 112 for outputting electrical signals. The signal input section 111 can be used to connect to a built-in or external input signal source. The input signal source can generate an input electrical signal. Similarly, the signal output section 112 can be used to output an output electrical signal.

[0112] The input and output electrical signals can be any of the three elements of Ohm's Law, excluding resistance. Specifically, they can be voltage or current signals. The types of the input and output electrical signals can be the same. For example, in one embodiment, both the input and output electrical signals of the circuit body 110 can be set as voltage signals. Of course, the types of the input and output electrical signals can also be different. For example, in other embodiments, the input electrical signal of the circuit body 110 is set as a voltage signal, and the output electrical signal is set as a current signal.

[0113] When both the input and output electrical signals of the circuit body 110 are set to voltage signals, furthermore, the voltage value of the input electrical signal and the current value in the circuit body 110 are constant values. In this way, it can be ensured that when the resistance value of the resistor 130 connected to the circuit body 110 is different, the output electrical signal will necessarily be different, thus meeting the above-mentioned requirement for direction detection.

[0114] To achieve the purpose of sliding resistance, in practical applications, the signal input section 111 and the signal output section 112 mentioned above can be connected to opposite ends of the resistor 130 along its length, respectively. Or as... Figure 5 As shown, the signal input segment 111 and the signal output segment 112 mentioned above are both connected to the same end of the resistor 130 along its length.

[0115] Specifically Figure 5Taking the structure shown as an example, the resistor 130 includes two resistor portions 134. The two resistor portions 134 are arranged at intervals along the width direction of the resistor 130. Each resistor portion 134 extends elongatedly along the length direction of the resistor 130. Both resistor portions 134 are conductive. And the resistance value of at least one resistor portion 134 is set in a positive correlation with its length as described above.

[0116] When the resistor 130 as described above includes a first resistor segment 131, an intermediate resistor segment 132, and a second resistor segment 133, two resistor portions 134 extend and are disposed throughout the first resistor segment 131, the intermediate resistor segment 132, and the second resistor segment 133.

[0117] The signal input section 111 is connected to one of the two resistor sections 134. The signal output section 112 is connected to the other of the two resistor sections 134. Both the signal input section 111 and the signal output section 112 are located at the same end of the resistor 130 along its length.

[0118] The portion of the adjusting member 120 that overlaps with the resistive member 130 is made of conductive material. This portion extends along the width of the resistive member 130 to simultaneously overlap with two resistive sections 134. The portions of the two resistive sections 134 located between the adjusting member 120 and the signal input section 111 and signal output section 112 are connected to the circuit body 110. Thus, the signal input section 111, the section of one resistive section 134 located between the signal input section 111 and the adjusting member 120, the section of another resistive section 134 located between the signal output section 112 and the adjusting member 120, and the signal output section 112 together constitute a complete detection circuit.

[0119] The specific structure of the resistor 130 that achieves the above purpose is not limited, for example... Figure 6 As shown, in one embodiment, one of the two resistive sections 134 is composed of a carbon film layer 135, and the other is composed of a silver film layer 136. When the resistive element 130 is arranged in a notched ring shape as described above, the silver film layer 136 and the carbon film layer 135 are arranged alternately along the width direction of the resistive element 130 (i.e., the radial direction of the notched ring). They can also be configured to have the same center. After being connected to the circuit body 110, both the carbon film layer 135 and the silver film layer 136 can form the desired resistance value, making them easier to detect sensitively.

[0120] And / or, the end of the resistor section 134 used to connect to the signal input section 111 is composed of a copper foil film layer 137. And / or the end of the resistor section 134 used to connect to the signal output section 112 is composed of a copper foil film layer 137. The copper foil film layer 137 has low resistance characteristics. Furthermore, the copper foil film layer 137 has strong oxidation resistance and reliable mechanical properties, making it more suitable for a stable connection with the signal input section 111 and the signal output section 112 of the circuit body 110.

[0121] Furthermore, the resistive section 134, which is composed of a carbon film layer 135, also has a silver film layer 136 provided at the connection between the carbon film layer 135 and the copper foil film layer 137. In this way, different resistance values ​​can be generated as the adjusting member 120 moves from the carbon film layer 135 to the silver film layer 136, so as to be sensitively detected that the rotating body 200a has rotated to near its limit position in the forward direction relative to the mating body 300a, or has rotated to near its limit position in the reverse direction.

[0122] Of course, there are no restrictions on the specific way in which the adjusting element 120 moves relative to the resistive element 130; it can move by sliding or by rolling.

[0123] In one specific embodiment, the adjusting member 120 includes a plate 121 and a block 122. The plate 121 extends along the width direction of the resistive member 130 to simultaneously cover two resistive portions 134. The block 122 is located at the end of the plate 121 opposite to the resistive member 130, and the block 122 has protrusions 122a corresponding to the two resistive portions 134, with the two protrusions 122a abutting against the plate 121.

[0124] Among them, plate 121 generally needs to have the required electrical conductivity:

[0125] The plate 121 can directly contact the two resistor sections 134, that is, abut against the two resistor sections 134, and can move arbitrarily between the first resistor section 131, the intermediate resistor section 132, and the second resistor section 133 along the first direction D1 or the second direction D2. At this time, the two protrusions 122a are abutted on the side of the plate 121 opposite to the resistor element 130, and the orthogonal projection area of ​​the two protrusions 122a in the direction of the line connecting the plate 121 and the resistor element 130 falls at least on the two resistor sections 134 respectively. In this way, the setting of the two protrusions 122a can, to a certain extent, at least strengthen the contact strength between the plate 121 and the two resistor sections 134.

[0126] Alternatively, the plate 121 may not directly contact the resistor section 134, but may be suspended above the resistor element 130. In this case, the two protrusions 122a may be conductive. The two protrusions 122a may pass through the side of the plate 121 opposite to the resistor element 130 and protrude from the side of the plate 121 toward the resistor element 130. At least the protruding portions of the two protrusions 122a, when projected onto the line connecting the plate 121 and the resistor element 130, fall on the two resistor sections 134 respectively. This ensures that the protruding portions of the two protrusions 122a abut against the two resistor sections 134 respectively, and can move arbitrarily between the first resistor section 131, the intermediate resistor section 132, and the second resistor section 133 along the first direction D1 or the second direction D2 described above.

[0127] Furthermore, the direction detection component 100 may also include a voltage divider resistor 140 connected in series within the circuit body 110. The voltage divider component is connected, for example, in series between the resistor 130 and the signal input segment 111.

[0128] Specifically, please combine Figures 5 to 6 In a practical application:

[0129] The voltage divider resistor 140 has a resistance value of, for example, 6Ω. This voltage divider resistor 140 is connected in series between the resistor 130 and the signal input segment 111. The signal input segment 111 can accept a control voltage, for example, 6V. The maximum resistance value of the first resistor segment 131 and the maximum resistance value of the intermediate resistor segment 132 are both set to 6Ω. The maximum resistance value of the intermediate resistor segment 132 is set to be close to 0Ω. Both the signal input segment 111 and the signal output segment 112 are connected to the end of the first resistor segment 131.

[0130] When the adjusting element 120 is at the middle resistance segment 132 of the resistive element 130, at least the first resistance segment 131 is fully connected to the circuit body 110 to form an effective resistance segment. At this time, the resistance value of the entire detection circuit is 6Ω of the voltage divider resistor 140 and 6Ω of the first resistance segment 131. The output voltage value of the signal output segment 112 is 3V.

[0131] When the adjusting element 120 travels along the first direction D1 and reaches the first resistance segment 131 of the resistive element 130, a portion of the first resistive element 130 is connected to the circuit body 110, forming an effective resistance segment. The resistance value of the entire detection circuit is 6Ω from the voltage divider resistor 140 and 6Ω to 0Ω from the first resistance segment 131. The total resistance value varies between 12Ω and 6Ω. The output voltage value of the signal output segment 112 approaches 0V from 3V.

[0132] When the adjusting element 120 travels along the second direction D2 at the second resistance segment 133 of the resistive element 130, the entire first resistance segment 131, the intermediate resistance segment 132, and a possible portion of the second resistance segment 133 together constitute the effective resistance segment. The resistance value of the entire detection circuit is 6Ω for the voltage divider resistor 140, 6Ω for the first resistance segment 131, and 0Ω to 6Ω for the second resistance segment 133. The total resistance value varies between 12Ω and 18Ω. The output voltage value of the signal output segment 112 ranges from 3V to approximately 4.5V.

[0133] In this way, changes in the output voltage value can be accurately detected.

[0134] Based on one or more of the above embodiments of the orientation detection component 100, specifically, when the orientation detection component 100 is specifically applied in a machine body and / or cleaning equipment, specifically... Figures 1 to 6Taking the structure shown as an example, the resistor 130 is adapted to extend in an arc shape in the circumferential direction of the rotating body 200a and the mating body 300a, as described above.

[0135] Therefore, the adjusting element 120 and the resistive element 130 can be assembled at any suitable position between the rotating body 200a and the mating body 300a:

[0136] Adjusting element 120 and / or resistor 130 may be exposed on the outer sides of rotating body 200a and mating body 300a. For example, when the fuselage module 200 and base module 300 are fitted together, the outer peripheral sidewall of base module 300 may laterally protrude to form a stepped surface 312. The outer peripheral sidewall of fuselage module 200 may laterally protrude to form a mounting surface 211. When fuselage module 200 and base module 300 are fitted together, stepped surface 312 and mounting surface 211 are at least partially facing each other. At this time, one of adjusting element 120 and resistor 130 is provided on stepped surface 312, and the other is provided on mounting surface 211. This is sufficient to ensure that when rotating body 200a rotates relative to mating body 300a, adjusting element 120 can be driven to move along the arc-shaped resistor 130. This allows the resistor 130 to be connected to the circuit body 110 at different lengths.

[0137] The stepped surface 312 and the mounting surface 211 are adapted one-to-one to the shape and size of the adjusting component 120 and the resistive component 130. For example, when the resistive component 130 is mounted on the stepped surface 312, the stepped surface 312 can be adapted to accommodate the resistive component 130 in a notched annular arrangement. This provides sufficient space for the resistive component 130 to be securely mounted and also helps to reduce the material consumption of the stepped surface 312. Correspondingly, when the adjusting component 120 is mounted on the mounting surface 211, the mounting surface 211 can be adapted to accommodate the shape of the adjusting component 120, which partially protrudes from the side wall of the body assembly 200. In this way, the inherent structural modifications to the body module 200 and / or base module in the cleaning equipment can be minimized, which helps to simplify the overall structure of the machine.

[0138] Of course, in other embodiments, the adjusting member 120 and / or the resistive member 130 may also be partially or completely housed inside the rotating body 200a and the mating body 300a. In this way, the adjusting member 120 and the resistive member 130 can be effectively protected by the structure of the rotating body 200a and the mating body 300a themselves. For example, external moisture or impurities can be blocked. This also helps to ensure effective electrical contact between the adjusting member 120 and the resistive member 130.

[0139] Once the direction detection component 100 detects whether the rotating body 200a is rotating in the forward or reverse direction relative to the mating body 300a, differential control of the two assist wheels 320 can be performed with reference to the following embodiment:

[0140] Specifically, the two assist wheels 320 of the cleaning device can be defined as the first wheel body and the second wheel body, respectively. Two drive mechanisms are configured: a first drive mechanism for driving the first wheel body to rotate, and a second drive mechanism for driving the second wheel body to rotate. When the cleaning device rotates forward, the first wheel body constitutes the inner wheel body, and the second wheel body constitutes the outer wheel body. Conversely, when the cleaning device rotates in the reverse direction, the second wheel body constitutes the inner wheel body, and the first wheel body constitutes the outer wheel body.

[0141] The cleaning equipment is equipped with a control device. The control device can be electrically connected to the aforementioned direction detection component 100. Upon receiving the output voltage value of the circuit body 110 and identifying whether the output voltage value is too high or too low, the control device can further determine whether the rotating body 200a is currently rotating in the forward or reverse direction relative to the mating body 300a.

[0142] The control device can also be electrically connected to the first drive mechanism and the second drive mechanism respectively. In this case, if the control device confirms that the rotating body 200a is currently rotating in the forward direction relative to the mating body 300a, it can control the first drive mechanism to decrease the speed of the first wheel and / or control the second drive mechanism to increase the speed of the second wheel. This achieves the purpose of creating a speed difference between the two assist wheels 320. Conversely, if the control device confirms that the rotating body 200a is currently rotating in the reverse direction relative to the mating body 300a, it can control the first drive mechanism to increase the speed of the first wheel and / or control the second drive mechanism to decrease the speed of the second wheel. This also achieves the purpose of creating a speed difference between the two assist wheels 320.

[0143] Furthermore, it should be noted that the cleaning device may directly include the direction detection component 100 provided in any of the embodiments described above. Alternatively, the cleaning device may include a body provided in any of the embodiments described above, and the body may in turn include the direction detection component 100 provided in any of the embodiments described above.

[0144] The cleaning equipment can be produced and applied independently. Alternatively, it can be produced and applied in conjunction with dedicated or shared base stations. In this case, the present invention also provides a cleaning system. The cleaning system includes the cleaning equipment and the base station described above.

[0145] The cleaning equipment and the base station have docked and disconnected states. In the disconnected state, the cleaning equipment can automatically or be manually operated by the user to perform various preset cleaning functions. In the docked state, the base station can be configured to perform preset functions on the cleaning equipment after docking, according to actual needs. These preset functions may include, but are not limited to, charging the cleaning equipment, collecting and cleaning the dirt gathered by the cleaning equipment, and disinfecting and cleaning the cleaning equipment's dustbin, etc.
