Abstract
Description
Technical Field
[0001] It belongs to the field of automobiles. Background Art
[0002] The windshield wiper is an indispensable device for cleaning transportation vehicles, including automobiles. Since the observation glass is similar to the driver's eyes, repeatedly improving the wiper performance, from the best to better, has become an important device that attracts social attention.
[0003] For this reason, among the existing materials, there are many distinctive creations, but the products should be further enriched. The main manifestations are as follows. In some cases, when the cleaning area of the glass is large, the performance is not ideal enough. For example, some use the guide groove to clean the dead corners, but it is easy to cause the combined swing arm to be not smooth enough during operation, and there is even a situation where there are dead corners and it cannot operate; some cannot make both ends of the support of the cleaning blade closely adhere to the glass for cleaning at the same time; some cannot expand the uses, such as being conveniently used for transportation vehicles in a wider field, or places or houses; some structures are not simple enough. Therefore, this application is proposed. Summary of the Invention
[0004] One of the purposes of this application is that it can clean large or small observation glasses, so it can be used for transportation vehicles in a wider field, including the field of automobiles. Second, under the condition of reliability, the structure is simple and easy to implement. Third, it expands the cleaning application field and can be used for cleaning large-area observation glasses in places or rooms, thus forming a wiper technical solution with good application effects in a wide field.
[0005] To achieve the above purpose, this application provides the following technical solutions: A double-ring cleaner includes a double-ring traction system that can receive power transmission, namely ring traction systems 1 and 2, and a cleaning system.
[0006] One side of each of the double-ring traction systems drives a cleaning system to work simultaneously.
[0007] The main components of the double-ring traction system are two conveyor belts 1 and 2. Conveyor belt 1 is placed around the periphery of the cleaning glass to form an annular pattern, which is the first annular traction system. The pattern formed by the first annular traction system covers all of the cleaning glass. Conveyor belt 2 forms a very narrow second annular traction system and is placed beside the first annular traction system. The double-ring traction system forms a logical motion mode of synchronization, same direction, and same linear speed after receiving power.
[0008] The cleaning system includes a power arm and a cleaning blade connected to the power arm.
[0009] Both ends of the power arm are respectively connected to the sides of the two conveyor belts where the movement directions are the same. Based on the above connection relationship, the following logical relationship can be formed.
[0010] Based on two conveyor belts, two working edges with the same synchronization, the same direction, and the same linear speed can be formed. Therefore, the two working edges can drive both ends of the cleaning system, starting from one end point of a certain section in the double-ring traction system, and then moving in the opposite direction to the other end point of the same section in the double-ring traction system, making a reciprocating motion, so as to achieve full coverage of the glass to be cleaned.
[0011] In the motion state where the double-ring traction system drives the cleaning system, the power arms of the cleaning system and the two connection points of the two conveyor belts become the power transfer points, which can form a traction method with the maximum torque of the double-ring traction system on the cleaning system. The two conveyor belts can obtain the best traction effect with the least force. From the perspective of force, it avoids the constraint of the size of the glass to be cleaned. Therefore, it can not only be used for the windshield in front of the driver's seat of a car with a smaller glass, but also be extended to other large-area glass transportation tools or buildings.
[0012] Also, since both ends of the power arm in the cleaning system are respectively connected to the two conveyor belts of the double-ring traction system, the two ends of the power arm will not be far from the surface of the glass to be cleaned. Thus, the cleaning wiper connected to the power arm will be in the best state with the glass to be cleaned, ensuring good cleaning performance when extended to large-area cleaning.
[0013] Preferably, the first ring traction system that can accept power transmission mainly includes a conveyor belt 1 with a conveying function and a series of supports 1 that limit the conveyor belt to only make a circular motion; one end of the series of supports of the first ring traction system is directly or indirectly fixed on the appropriate main body around the glass to be cleaned, ensuring that the enclosed figure encompasses and covers the area of the glass to be cleaned. At the same time, the figure determined by fixing the conveyor belt 1 is placed outside the series of supports 1 on the periphery of the enclosed figure. Under the action of external power, the conveyor belt 1 will make a reciprocating motion along the edge of the figure determined outside the series of supports 1.
[0014] Preferably, the figure enclosed by the conveyor belt 1 of the first ring traction system is a square 1. The area of the square 1 covers the area to be cleaned. The two long sides of the square 1 are equal to or exceed the two longest end points of the area to be cleaned. The other two short sides of the square 1 should be equal to or exceed the lengths of the two shortest end points in the other direction of the area to be cleaned. The two opposite sides A11 and A12 of the square 1 are the main working sections of the first ring traction system, and A11 and A12 have the same length.
[0015] Among them, the second annular traction system capable of accepting power transmission mainly includes a conveyor belt 2 with a conveying function and a series of supports 2 that restrict the conveyor belt 2 to only perform circular motion. One end of the series of supports of the second annular traction system is directly or indirectly fixed on the main body of the determined figure of the conveyor belt 2. The conveyor belt 2 is placed outside the series of supports 2 surrounding the periphery of the enclosed figure. Under the action of external power, the conveyor belt 2 will perform reciprocating motion around the series of supports 2.
[0016] Preferably, the figure enclosed by the second annular traction system is a quadrilateral 2. Two opposite sides A21 and A22 of the quadrilateral 2 are the main working sections of the second annular traction system. The two main working sections A21 and A22 of the second annular traction system and the two main working sections A11 and A12 of the first annular traction system have the same length, and the two short sides of the quadrilateral 2 form the shortest length.
[0017] Preferably, the two conveyor belts of the double annular traction system enclose two quadrilaterals. The main working section A11 of the quadrilateral 1 and the main section A21 of the quadrilateral 2 are closely adjacent to each other, forming an operable connection method of synchronization, same direction, and same linear speed. After receiving the transmission of external power, the two quadrilaterals can form a situation where the working sections connecting the power arms are synchronized, have the same linear speed, and reciprocate in the same direction, creating an important basis for the double-ring traction operation.
[0018] Preferably, the connection relationship between the power arm of the cleaning system and the double annular traction system is that one end of the power arm is directly or indirectly connected to the A12 working section of the quadrilateral 1, and the other end of the power arm is directly or indirectly connected to the A22 working section of the quadrilateral 2. And the two connection points are two points at the same position of the two quadrilaterals, forming an ideal perpendicular 90-degree position relationship between the power arm connecting the two conveyor belts and the working section, and a height relationship where the power arm is higher than the supports and A11 and A21, so as to form a situation where the power arm can move freely on the working section, driving the cleaning system to clean the covered area comprehensively.
[0019] Preferably, the described double annular cleaner further includes a power system. The power system includes a bidirectional motor and a supporting circuit part that controls the logical law of the bidirectional motor. Under the action of the power system, the double traction system drives the power arm in the cleaning system to perform parallel reciprocating motion in two directions on the working section, thereby realizing the comprehensive cleaning of the cleaning glass.
[0020] Preferably, the supporting circuit part in the power system includes a motor speed control circuit, two steering devices, a logic control circuit, and a motor conversion circuit.
[0021] The connection relationship is: the system power supply is connected to the input end of the motor speed control circuit, and the output end of the motor speed control circuit is connected to the working power input end of the motor conversion circuit.
[0022] Two steering devices are arranged at the points where the power arm of the cleaning system needs to change direction. The output ends of the two steering devices are connected to the two input ends of the logic control circuit. The two output ends of the logic control circuit are respectively connected to the two steering signal input ends of the motor conversion circuit. The two output ends of the motor conversion circuit are the two output ends of the supporting circuit part and are connected to the power input ends of the bidirectional motor, so that the supporting circuit part can send three signals with precisely controllable polarity interchange and adjustable speed to the power input ends of the bidirectional motor.
[0023] Based on the composition, connection and structure of claims 1-9, the following working states and combined features are formed: After receiving power, the double-ring traction system can drive the cleaning system to move to one end of the working section in the double-ring traction system, and then move in the reverse direction to the other end of this section in the double-ring traction system, making a reciprocating motion. Also, based on the relevant technical features described in claims 1 to 9, the entire glass to be cleaned can be covered.
[0024] When the double-ring traction system is in motion, the two connection points between the power arm of the cleaning system and the two conveyor belts become the power transfer points between the double-ring traction system and the cleaning system, and can form a traction method with the maximum torque. The two conveyor belts can obtain the best traction effect with the least force. From the perspective of force, it avoids the constraint of the size of the glass to be cleaned. Therefore, it can not only be used for the windshield in front of the driver's seat of a car with a small glass area, but also can be extended to other means of transportation or buildings with a large glass surface.
[0025] The double-ring traction system can be in the form of one large and one small. The first ring traction system, i.e., the large ring system, covers all the areas to be cleaned, and the second ring traction system, i.e., the small ring system, forms the narrowest form, resulting in a scientific combination with multiple benefits.
[0026] Since both ends of the power arm in the cleaning system are respectively connected to the two conveyor belts of the double-ring traction system, the two ends of the power arm will not be far from the surface of the glass to be cleaned. Thus, the cleaning wiper connected to the power arm will be in the best state with the glass to be cleaned, ensuring good cleaning performance when extended to large-area cleaning. Therefore, it can not only be used for the windshield in front of the driver's seat of a car with a small glass area, but also can be used on other means of transportation or buildings with a large glass surface, ensuring the cleaning effect.
[0027] Based on the power of the power system, the power can be effectively transmitted to the double-ring traction system in both forward and reverse directions. Based on the synchronization, same-direction, and same linear speed working sections that can be formed by the double-ring traction system, and based on the fact that the operation mode of the power arm is parallel movement without an angular relationship, a reliable logical relationship is fully ensured, and various unsmooth situations such as dead corners are not generated during the movement of the cleaning system.
[0028] The supporting circuit part forms reliable forward and reverse control functions, precise control functions for forward and reverse logic points, and optimized functions for adjusting speed for the double-ring traction system. Advantages
[0029] Based on all the multiple features in the applicant's measures, three major combined feature effect series can be formed; First, the macro concept of double-ring traction is adopted, which has more prominent advantages than other methods.
[0030] Second, the macro concept of double-ring traction can be transformed into a simple structural method.
[0031] Third, the combination of the power system and the double traction that can accept power transmission can form a product that combines mechanical and electrical integration.
[0032] Since all three major combined feature series have great characteristics, the following advantages are available: 1. Expand the uses of the windshield wiper.
[0033] Since the area of the glass to be cleaned can be very large or relatively small, and is basically not restricted by the shape, it can be used in the following places and for the following purposes.
[0034] 1.1. It can be used for cleaning the observation glass on the driving table of a vehicle with a relatively small cleaning area, such as a car; it can also be used for vehicles that require a relatively large cleaning area.
[0035] 1.2. It can be used for cleaning large glass for external observation in places such as writing rooms, such as floor-to-ceiling observation glass.
[0036] When used in such places, the greatest advantage is to avoid various inconveniences caused by high-altitude cleaning operations, so that the cleaning and maintenance can be made more flexible.
[0037] 1.3. It is used for daily maintenance of the observation glass of vehicles to keep it clean and maintained in a normal state.
[0038] 2. Good cleaning effect.
[0039] 2.1. The double-ring traction system and the cleaning system cooperate flexibly and coordinately, and basically no dead corners will be generated in the application of item "1".
[0040] 2.2. Overcome the problem that the wiper cannot be closely attached to the object to be cleaned in some technologies, which affects the cleaning effect.
[0041] 2.3. The combination of mechanical and electrical components has a good effect.
[0042] III. The mechanical structure is simple, without relatively complex components or structural methods, easy to implement, and has a low cost. Description of the Drawings

[0051] It should be noted that in this application, the terms "include", "comprise", "have" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.
[0052] In this application, unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated. It can be directly connected or indirectly connected through an intermediate medium (such as mechanical parts). For those of ordinary skill in the art, the specific meaning of the above terms in this application can be understood according to specific circumstances.
[0053] I. Several representative ways of windshield wipers in the prior art.
[0054] In the prior art, some ways are to change the rotation of one end of the original windshield wiper at the origin, and use a motor to drive the windshield wiper to make a parallel sliding on the edge track, expecting to achieve a comprehensive cleaning effect. However, the actual situation of this way is that only one end of the windshield wiper is close to the track, and the other end of the windshield wiper is far from the track. Therefore, the force on the other end of the windshield wiper is weaker than that on the end close to the track. The larger the area of the glass to be cleaned, the smaller the force on the end of the windshield wiper far from the track. In addition, during large-area cleaning, the windshield wiper cannot fully adhere to the glass to be cleaned, and thus the ideal cleaning effect cannot be achieved.
[0055] There are also some ways that do not change the main operation mode of the traditional windshield wiper, but only add a guide groove track around the glass, and use a combination of telescopic fixed and sliding windshield wipers to move along the windshield frame in the guide groove track to achieve a comprehensive cleaning effect. It has been found through research that the force application point of the windshield wiper in this way has not changed, and the component force generated by the movement direction along the track makes the combination of the windshield wiper extend or contract as it moves along the track to meet large-area cleaning. Because the traction force is not strong enough, during the movement of the windshield wiper and the track, it is easy for the movement to be unsmooth, resulting in an angle and making it difficult for the windshield wiper to continue running in the track.
[0056] Some have relatively good effects, but their structures are complex, causing various inconveniences, including difficulties in popularization and other problems. Therefore, it is necessary to enrich the varieties of windshield wipers.
[0057] II. Difficulties in this application This application aims to overcome the deficiencies in item "I", enrich and improve the varieties of windshield wipers. For this purpose, the present invention has carried out creative work on ten technical measures, which include the following difficulties: First, the concept of double-ring traction is required; second, the double rings of the double-ring traction form a matching relationship of one large and one small; third, the double rings should have a relationship of synchronization, same direction, and same linear speed; fourth, when cleaning a large area of glass, there should be a good contact and close-fitting relationship between the power arm of the cleaning system and the glass being cleaned; fifth, the performance is improved by the supporting circuit; sixth, the structure is simple and easy to implement.
[0058] III. Implementation of technical measures.
[0059] 1. A double-ring cleaner includes a double-ring traction system that can receive power transmission, namely, ring traction systems 1 and 2, and a cleaning system.
[0060] One side of each of the double-ring traction systems drives a cleaning system to work simultaneously.
[0061] The main components of the double-ring traction system are two conveyor belts 1 and 2. Conveyor belt 1 is placed around the periphery of the glass to be cleaned to form an annular shape, which is the first ring traction system. The shape enclosed by the first ring traction system covers the entire glass to be cleaned. Conveyor belt 2 encloses a very narrow second ring traction system and is placed beside the first ring traction system. The double-ring traction system forms a logical motion mode of synchronization, same direction, and same linear speed after receiving power.
[0062] The cleaning system includes a power arm and a cleaning blade connected to the power arm.
[0063] Both ends of the power arm are respectively connected to the sides of the two conveyor belts where the moving directions are the same. Based on the above connection relationship, the following logical relationship can be formed: 1.1. Based on the two conveyor belts, two working sides with synchronization, same direction, and same linear speed can be formed. Therefore, the two working sides can drive both ends of the cleaning system, starting from one end point of a certain section of the double-ring traction system and then moving in the reverse direction to the other end point of the same section of the double-ring traction system, making a reciprocating motion, thereby achieving full coverage of the glass to be cleaned.
[0064] 1.2. In the state where the double-ring traction system drives the cleaning system, the two connection points between the power arm of the cleaning system and the two conveyor belts become the power transmission points, which can form a traction method with the maximum torque of the double-ring traction system on the cleaning system. The two conveyor belts can obtain the best traction effect with the smallest force. From the perspective of force, it avoids the constraint of the size of the glass to be cleaned. Therefore, it can be used not only for the windshield in front of the driver's seat of a car with a small glass area but also can be extended to other large-area glass surfaces of transportation vehicles or buildings.
[0065] 1.3. Also, since both ends of the power arm in the cleaning system are respectively connected to the two conveyor belts of the double-ring traction system, the two ends of the power arm will not move far away from the surface of the glass to be cleaned. As a result, the cleaning blade connected to the power arm will be in the best state with the glass to be cleaned, ensuring good cleaning performance when extended to large-area cleaning.
[0066] 2. The first ring traction system that can accept power transmission mainly includes a conveyor belt 1 with a conveying function and a series of supports 1 composed of multiple supports that restrict the conveyor belt to only move in a circular motion. One end of the series of supports of the first ring traction system is directly or indirectly fixed on an appropriate main body around the glass to be cleaned, ensuring that the enclosed figure encompasses and covers the area of the glass to be cleaned. At the same time, the figure determined by the conveyor belt 1 is fixed, and the conveyor belt 1 is placed outside the series of supports 1 on the periphery of the enclosed figure. Under the action of external power, the conveyor belt 1 will reciprocate along the edge of the figure determined outside the series of supports 1.
[0067] The explanations for the above measures are as follows: In implementation, the significance of the series of supports 1 composed of multiple supports that restrict the conveyor belt to only move in a circular motion is as follows: First, the main function of the series of supports 1 is to fix or determine the figure determined by the conveyor belt. Therefore, the structure and shape of the series of supports are diverse. For example, they can be small bodies with various cross-sectional shapes, or they can be long strip-shaped bodies with a cross-section. In the example, they are expressed as small cylinders, and the conveyor belt can make circular motions within the ring determined by the supporting objects. The second significance is that the supporting objects have a structure or shape that restricts the conveyor belt from detaching from the supports. To achieve this purpose, there are various well-known methods. One of the forms is shown in the appendix Figure 4 where the small cylinder has a form with larger ends and a smaller middle part, restricting the conveyor belt to only move in the smaller middle part and make circular motions, and preventing it from detaching from the supports. The third significance is that another type of limiting object can be added, which only serves to restrict the conveyor belt from detaching from the supports.
[0068] 3. The figure enclosed by the conveyor belt 1 of the first ring traction system is a quadrilateral 1. The area of the quadrilateral 1 covers the area to be cleaned. The two long sides of the quadrilateral 1 are equal to or exceed the two longest endpoints of the area to be cleaned. The other two short sides of the quadrilateral 1 should be equal to or exceed the lengths of the two shortest endpoints in the other direction of the area to be cleaned. The two opposite sides A11 and A12 of the quadrilateral 1 are the main working sections of the first ring traction system, and A11 and A12 have the same length.
[0069] The explanations for the above measures are as follows: As Figure 2As shown, for the normal working section of the quadrilateral, the long side of the quadrilateral is mainly selected. The long side is the side connecting the power arm and is also the working section of the movement voyage of the power arm. The main advantage is that it can reduce the length of the power arm, which is beneficial to the contact between the cleaning blade of the connected power arm and the cleaning glass. However, under the condition of meeting the previous requirements, selecting the short side of the quadrilateral as the working section can reduce the movement voyage and improve work efficiency. Therefore, the selection of the working section can be determined according to the required environment.
[0070] 4. The second annular traction system capable of accepting power transmission mainly includes a conveyor belt 2 with a conveying function and a series of supports 2 that restrict the conveyor belt 2 to only make a surrounding movement. One end of the series of supports of the second annular traction system is directly or indirectly fixed on the main body of the determined figure of the conveyor belt 2. The conveyor belt 2 is placed outside the series of supports 2 surrounding the periphery of the enclosed figure. Under the action of external power, the conveyor belt 2 will make a reciprocating movement around the series of supports 2.
[0071] The above measures are explained as follows: The relevant key points of the second annular traction system are the same as those of the first annular traction system.
[0072] 5. The figure enclosed by the second annular traction system is a quadrilateral 2. Two opposite sides A21 and A22 of the quadrilateral 2 are the main working sections of the second annular traction system. The two main working sections A21 and A22 of the second annular traction system and the two main working sections A11 and A12 of the first annular traction system have the same length, and the two short sides of the quadrilateral 2 form the shortest length.
[0073] The above measures are explained as follows: Based on the fact that the first annular traction system has covered the cleaning object, the main function of the second annular traction system is to generate a synchronous, same linear speed, and same-direction side for the first annular traction system. Therefore, the short side of the quadrilateral can be in the shortest form, that is, only the width of the support is used as the width of the short side of the quadrilateral 2. For example, Figure 1 in the shown example, if small cylinders are used as the supports and only two small cylinders can complete the shape of the quadrilateral, then the diameter of the small cylinder is the width of the short side of the quadrilateral 2, forming the narrowest second annular traction system, which produces various scientific combinations and is beneficial to installation.
[0074] 6. The two conveyor belts of the double annular traction system enclose two quadrilaterals. The main working section A11 of the quadrilateral 1 and the main section A21 of the quadrilateral 2 are closely close to each other, forming an operable connection method of synchronous, same-direction, and same linear speed; after receiving the transmission of external power, the two quadrilaterals can form a situation where the working sections connecting the power arms run synchronously, with the same linear speed, and in the same direction reciprocally, creating an important foundation for the double-ring traction operation.
[0075] The above measures are described as follows: The principle of the double-ring traction system to generate synchronous, same-direction, and same linear velocity relationships is as Figure 2 shown. Mainly due to the existence of the connection point 500 in the Figure 2 attachment.
[0076] Specifically, for the double-ring traction system, although the formed areas are different and the perimeters are different. However, the side lengths of the working sections connecting the power arms are the same length. Coupled with the formed composition and structure, as long as the "linear velocities" of conveyor belts 1 and 2 are the same, the required logical situations generated by the working sections of the double-ring traction system will be the same. Because the main working sections of the double-ring traction system are of the same length, as long as the "linear velocities" of the endpoints are the same, the distances traveled in the same time will be the same, and the motion trajectories of the two connection endpoints of the power arm can be ensured to be of the same length. Therefore, ensuring that the common working sides of the double-ring traction system of this application form the same "linear velocity" is the key to the technology. The method adopted in the technical measures is that a certain point of the adjacent working sections A11 and A21 in the two ring diagrams is fixedly connected, forming the simplest relationship of same-direction synchronization and same linear velocity that can be operated.
[0077] It should be noted that: As Figure 2 shown, for the connection point 500 of the adjacent working sections A11 and A21, a very "expanded" drawing method is adopted, mainly to prominently represent the connectable relationship. A11 and A21 should be in a close relationship and there should be no gap.
[0078] 7. The connection relationship between the power arm of the cleaning system and the double-ring traction system is that one end of the power arm is directly or indirectly connected to the A12 working section of the square 1, and the other end of the power arm is directly or indirectly connected to the A22 working section of the square 2. And the two connection points are two points at the same position of the two squares, forming an ideal perpendicular 90-degree positional relationship between the power arm connecting the two conveyor belts and the working sections, as well as the height relationship between the power arm and the support and A11, A21, so as to form a situation where the power arm can move freely in the working section, driving the cleaning system to clean the covered area comprehensively.
[0079] The above measures are further described as follows: There are many methods to raise the height of the power arm relative to the support and the two working sections A11 and A21. In the example, the method of bending the two ends connected by the power arm into 90 degrees is adopted, and a section generated by the bending is used to increase the height of the power arm from the support and the two working sections A11 and A21.
[0080] In the case where the glass area to be cleaned is very large, guide grooves can be added to the working sections of the two conveyor belts to increase the hardness of the working sections of the two conveyor belts, avoiding the cleaning blade connected by the power arm being far away from the glass in the large-area working state and ensuring the cleaning effect.
[0081] The power arm can be made into a selectively adjustable manner according to the specific installation requirements of the environment.
[0082] 8. The described double-ring cleaner further includes a power system. The power system includes a bidirectional motor and a supporting circuit part that controls the logical rules of the bidirectional motor. Under the action of the power system, the double-traction system drives the power arm in the cleaning system to make parallel reciprocating motions in two directions on the working section, thereby achieving a comprehensive cleaning of the glass to be cleaned.
[0083] 9. The supporting circuit part in the power system includes a motor speed control circuit, two steering devices, a logic control circuit, and a motor conversion circuit.
[0084] The connection relationship is as follows: The system power supply is connected to the input end of the motor speed control circuit, and the output end of the motor speed control circuit is connected to the working power supply input end of the motor conversion circuit.
[0085] The two steering devices are arranged at the points where the power arm of the cleaning system needs to change direction. The output ends of the two steering devices are connected to the two input ends of the logic control circuit. The two output ends of the logic control circuit are respectively connected to the two steering signal input ends of the motor conversion circuit. The two output ends of the motor conversion circuit are the two output ends of the supporting circuit part and are connected to the power supply incoming line ends of the bidirectional motor, forming that the supporting circuit part can send three signals with precisely controllable polarity interchange and adjustable speed to the power supply incoming line ends of the bidirectional motor.
[0086] The above measures are explained as follows: The motor speed control circuit is composed of an existing well-known speed control circuit, that is, an electronic functional circuit with a switching function and an oscillation circuit. The incoming line end of the electronic switch is connected to the system power supply, the outgoing line end of the electronic switch is connected to the working power supply end of the motor conversion circuit, and the output end of the oscillation circuit is connected to the control end of the electronic switch. By adjusting the oscillation frequency of the oscillation circuit, the intermittent voltage output at the output end of the electronic switch can be adjusted to achieve the purpose of adjusting the motor speed. This existing speed adjustment circuit is a classic circuit because the peak value of the output voltage does not change, and the transient torque generated by the motor basically does not change.
[0087] The motor conversion circuit is a well-known bridge circuit composed of two relays. The two common ends of the contact switches of the two relays are the output ends of the steering circuit and are connected to the two incoming line ends of the bidirectional motor. The two normally closed ends of the contact switches of the two relays are connected to the system ground wire, and the two normally open ends of the contact switches of the two relays are connected to the working power supply input end of the bridge, that is, connected to the output end of the motor speed control circuit.
[0088] The conversion devices 1 and 2 are devices that can emit signals after a moving body arrives in place, including various devices in the mechanical major series and the electronic major series. In the example, a very common mechanical limit switch is used. Two mechanical limit switches are respectively set at both ends of the working section, and the output ends of the two mechanical limit switches are respectively connected to the two input ends of the logic control circuit. The logic control circuit is a circuit that can maintain a state after receiving a signal and maintain another state after receiving a new different type of signal. In the example, a commonly used Rs circuit is adopted. The two input ends of the Rs circuit are respectively connected to the two output ends of the mechanical limit switch, and the two output ends of the Rs circuit are respectively connected to the two input ends of the motor conversion circuit.
[0089] One end controlled by the energization of the two relay coils respectively becomes the two signal input ends of the motor conversion circuit.
[0090] The above composition and connection relationship form the following logical principles. First, after the power system transmits power to the double-loop traction system that can accept power transmission, the working sections of conveyor belts 1 and 2 can move in two opposite directions to relevant positions, so that the cleaning blades in the cleaning system can perform cleaning work in two opposite directions. Second, under the action of the conversion device, the starting and ending positions of the cleaning blades in the cleaning system will be accurately controlled. Third, adjusting the oscillation frequency can adjust the cleaning speed of the cleaning blades.
