DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0034] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0035] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0036] With the rapid development of smart cockpits, the high integration of cockpit functions, the gradual reduction of physical buttons and the improvement of cockpit entertainment, the display screen has become the main medium for human-machine interaction between users and the cockpit. Various functions of the vehicle are realized by touching and clicking the interface displayed on the display screen, so that the user's fingerprints, sweat and other attachments will be left on the surface of the display screen. Over time, the dirt on the surface of the display screen will increase with the increase in the number of user operations, and the touch surface of the display screen will become very dirty, affecting the user experience.

[0037] There is currently no method on the market that can completely solve the problem of fingerprint residue, and the fingerprint residue needs to be wiped clean by the car owners themselves.

[0038] In order to solve the above problems to a certain extent, the first aspect of the present application provides a cleaning device, such as Figure 1 As shown, the cleaning device includes a driving component 1, a cleaning component 2, a guide component and a sensing component 4, wherein:

[0039] The driving assembly 1 is connected to the cleaning assembly 2 in a transmission manner, and is used to drive the cleaning assembly 2 to move along the extension direction of the guide assembly;

[0040] The sensing components 4 are located at both ends of the extending direction of the guide component. The sensing components 4 are used to transmit signals to the driving component 1 when it is determined that the cleaning component 2 is located at the end of the guide component.

[0041] It is understandable that the cleaning component 2 can be used to contact the screen to complete the cleaning work. The driving component 1 is connected to the cleaning component 2 in a transmission manner, which is conducive to the cleaning component 2 contacting different positions of the screen to improve the cleaning effect. The sensing component 4 is located at both ends of the guide component, and transmits a signal to the driving component 1 when the cleaning component 2 is located at the end of the guide component, which is conducive to the driving component 1 changing the moving direction of the cleaning component 2 according to the signal, so that the cleaning component 2 is conducive to cleaning the screen multiple times, thereby improving the cleaning effect and reducing the residual fingerprints.

[0042] In the embodiment of the present application, the extension direction of the guide component can be the extension direction of any one of two axes intersecting on a horizontal plane.

[0043] In the embodiment of the present application, the driving component 1 can convert movement or rotation in other directions into movement along the extension direction of the guide component, thereby driving the cleaning component 2 to move.

[0044] In the embodiment of the present application, the driving component 1 is transmission-connected with the cleaning component 2, and can drive the cleaning component 2 to move back and forth along the extension direction of the guide component to achieve cleaning of the screen.

[0045] In the embodiment of the present application, the cleaning component 2 can generate power by itself to clean the screen, or it can use the driving force generated by the driving component 1 to clean the screen.

[0046] In the embodiment of the present application, when the sensing component 4 transmits a signal to the driving component 1, the driving component 1 can change the moving direction of the cleaning component 2, so that the screen can be cleaned repeatedly.

[0047] In the embodiment of the present application, each time the driving component 1 receives a signal, the moving direction of the cleaning component 2 changes once.

[0048] In the embodiment of the present application, the signal may be an electrical signal such as a voltage signal or a current signal, or may be a signal such as light, sound, or vibration.

[0049] In the embodiment of the present application, the end of the guide component may refer to any one of the two ends of the guide component where the sensing component 4 is located.

[0050] In some of the embodiments of this application, Figure 1As shown, the driving assembly 1 includes a motor 11, a driving gear 12, a driven gear 13 and a conveyor belt 14. The motor 11 is connected to the driving gear 12 in a transmission manner. The driving gear 12 and the driven gear 13 are both located in the conveyor belt 14 and meshed with the conveyor belt 14. The cleaning assembly 2 is connected to the conveyor belt 14.

[0051] It is understandable that the motor 11 can drive the driving gear 12 to rotate, and the rotating driving gear 12 transmits power to the conveyor belt 14 through meshing, so as to realize the movement of the conveyor belt 14 along the extension direction of the guide assembly, thereby realizing the movement of the cleaning assembly 2. At the same time, the driven gear 13 can support the conveyor belt 14, which is conducive to the conveyor belt 14 being able to move along the extension direction of the guide assembly at the driving gear 12 and the driven gear 13.

[0052] In the embodiment of the present application, the motor 11 can be connected to the driving gear 12 by means of welding, clamping, key connection, etc., thereby driving the driving gear 12 to rotate.

[0053] In the embodiment of the present application, the cleaning component 2 can be connected to the conveyor belt 14 by welding, clamping, key connection, etc. For example, the cleaning component 2 can be attached to the side of the conveyor belt 14 away from the driving gear 12, and the conveying length of the conveyor belt 14 is limited by the sensing component 4. After the sensing component 4 transmits a signal to the driving component 1, the moving direction of the cleaning component 2 will change, so the cleaning component 2 will only move in a straight line direction, and will not rotate around the driving gear 12 or the driven gear 13.

[0054] In the embodiment of the present application, the driving gear 12 can be arranged with a rotating shaft in the guide assembly so that the driving gear 12 can rotate under the support of the rotating shaft.

[0055] In the embodiment of the present application, the driven gear 13 can be arranged with a rotating shaft in the guide assembly so that the driven gear 13 can rotate under the support of the rotating shaft.

[0056] In some of the embodiments of this application, Figure 1 and Figure 3 As shown, the guide assembly includes a guide rail 31 , the driving gear 12 , the driven gear 13 and the conveyor belt 14 are all located in the guide rail 31 , and the cleaning assembly 2 includes a connecting rod 21 , which extends into the guide rail 31 and is connected to the conveyor belt 14 .

[0057] It can be understood that the connecting rod 21 extends into the guide rail 31 and is connected to the conveyor belt 14, which is conducive to the cleaning component 2 to keep moving along its extension direction and reduce the sagging of the conveyor belt 14 due to its own gravity and the gravity of the cleaning component 2, thereby improving the cleaning efficiency.

[0058] In the embodiment of the present application, one side of the guide rail 31 may have a slide groove 311 for the connecting rod 21 to pass through, which is conducive to the movement of the connecting rod 21 along the extension direction of the guide assembly.

[0059] In some of the embodiments of this application, Figure 1 As shown, the sensing component 4 includes two pressure sensors 41 and two pressure springs 42. Each pressure spring 42 is connected to the guide rail 31 through a pressure sensor 41. The two pressure springs 42 are respectively located at the two ends of the guide rail 31 and are arranged opposite to each other. The pressure spring 42 is used to contact the connecting rod 21 to generate a signal. When the driving component 1 receives the signal from the pressure sensor 41, the moving direction of the cleaning component 2 is changed.

[0060] It is understandable that the pressure spring 42 can be deformed by the pressure of the connecting rod 21 and generate pressure on the pressure sensor 41. The pressure sensor 41 under pressure can generate an electrical signal, which is received by the driving component 1 to change the moving direction of the cleaning component 2, thereby improving the cleaning effect.

[0061] In the embodiment of the present application, one end of the connecting rod 21 located in the guide rail 31 can form a slider 211. When the slider 211 contacts the pressure spring 42, it can cause the pressure spring 42 to deform and generate elastic force, so that the pressure sensor 41 can generate an electrical signal, thereby causing the moving direction of the cleaning component 2 to change.

[0062] In an embodiment of the present application, the guide rail 31 includes a partition 32, which is located between the driving gear 12 and the driven gear 13, and the pressure sensor 41 is installed on the side of the partition 32 facing the driven gear 13, so as to prevent the cleaning component 2 from moving to the periphery of the driving gear 12 along the conveying direction of the conveyor belt 14.

[0063] In the embodiment of the present application, the partition 32 can form a gap with the side of the guide rail 31 for the connecting rod 21 to extend into, and the gap can allow the conveyor belt 14 to pass through, so as to facilitate the conveyor belt 14 to drive the connecting rod 21 to move.

[0064] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the cleaning assembly 2 includes a shell 22 and a roller 23 . The shell 22 has a receiving cavity 2201 . At least a portion of the outer side surface of the roller 23 is located in the receiving cavity 2201 , and another portion is exposed from the receiving cavity 2201 .

[0065] It is understandable that the cleaning assembly 2 needs to maintain contact with the screen during the movement to complete the cleaning. In this embodiment, by exposing a portion of the roller 23 to the accommodating cavity 2201, the roller 23 can maintain contact with the screen before the housing 22, which is conducive to improving its cleaning performance.

[0066] In the embodiment of the present application, the outer side of the roller 23 may be arranged with soft materials for cleaning the screen, such as fluff.

[0067] In the embodiment of the present application, both ends of the drum 23 can be connected to the housing 22 and can rotate relative to the housing 22, so as to improve the cleaning efficiency. The two ends of the drum 23 can be arranged as grooves, and the housing 22 is provided with protrusions at corresponding positions, which is conducive to the rotation of the drum 23 and can support the drum 23.

[0068] In the embodiment of the present application, the drum 23 is mainly cylindrical in shape, the outer side surface may refer to the side surface of the drum 23 , and the two ends may refer to the upper and lower bottom surfaces of the drum 23 .

[0069] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the shell 22 includes an inner shell 221 and an outer shell 222. The inner shell 221 has a accommodating cavity 2201. The inner shell 221 is located in the outer shell 222. The inner shell 221 and the outer shell 222 are connected via a guide portion 223 and a reset portion 224. The inner shell 221 can move along the direction guided by the guide portion 223. The reset portion 224 is used to provide a reset force to the inner shell 221 after the inner shell 221 moves.

[0070] It is understandable that the roller 23 is located in the inner shell 221 and can move along the guide portion 223 in the outer shell 222 with the inner shell 221, which is conducive to the roller 23 being attached to the screen during the movement to complete the cleaning. The reset portion 224 can generate a reset force when the roller 23 is subjected to the pressure of the screen, and the reset force can make the roller 23 return to its original position, so it is conducive to the roller 23 being attached to the screen.

[0071] In the embodiment of the present application, the guiding direction of the guide portion 223 may be a direction perpendicular to the moving direction of the cleaning component 2 .

[0072] In the embodiment of the present application, the reset part 224 can generate a signal through a sensor after the inner shell 221 moves, and the signal generates power through a driving element, and the power acts on the inner shell 221 or the roller 23, so that the roller 23 can generate a corresponding force on the screen, so that the roller 23 can stick to the screen.

[0073] In the embodiment of the present application, the reset portion 224 may be a spring 42, which is compressed when the inner shell 221 moves in the direction guided by the guide portion 223; when the roller 23 is not attached to the screen, the elastic force generated by the compression can cause the inner shell 221 to return to the position before the movement. In the embodiment of the present application, the position of the inner shell 221 or the roller 23 may refer to the relative position with respect to the outer shell 222.

[0074] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the inner shell 221 has a guide groove on one side facing the outer shell 222 , and the outer shell 222 has a limiting portion 2221 on one side facing the inner shell 221 . One end of the guide portion 223 extends into the guide groove, and the other end of the guide portion 223 is connected to the limiting portion 2221 .

[0075] It can be understood that the guide groove allows one end of the guide portion 223 to move. Since the other end of the guide portion 223 is connected to the limiting portion 2221, it cannot move relative to the limiting portion 2221. Therefore, when the roller 23 is squeezed by the screen, the guide portion 223 as a whole maintains a relatively fixed position, and the inner shell 221 moves under the guidance of the guide portion 223. This is beneficial for the reset portion 224 to generate a reset force, and is also beneficial for the roller 23 to maintain contact with the screen.

[0076] In the embodiment of the present application, the number of the guide portions 223 may be 8, and the 8 guide portions 223 are evenly distributed on two opposite sides of the inner shell 221, which is helpful to improve the stability of the inner shell 221 during the movement.

[0077] In the embodiment of the present application, the limiting portion 2221 and the guide portion 223 can be connected by means of snapping, welding, bonding, etc., which is conducive to the guide groove being exposed from the shell 222 under the action of the guide portion 223.

[0078] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the reset portion 224 connects the inner shell 221 and the outer shell 222 . The reset portion 224 is used to apply a reset force to the inner shell 221 . The extending direction of the reset force intersects with the moving direction of the guide portion 223 .

[0079] It can be understood that the reset force can press the roller 23 against the screen to achieve fit with the screen on the one hand, and on the other hand it is also conducive to the automatic return of the inner shell 221, which is conducive to the roller 23 being able to be pressed against the screen by the reset force next time after completing a work.

[0080] In the embodiment of the present application, the reset portion 224 may be a spring 42, and the number of the springs 42 may be 8, and the 8 springs 42 are arranged on the same side of the inner shell 221. The side where the spring 42 is located is the side of the inner shell 221 away from the drum 23.

[0081] A second aspect of the present application provides a car, which includes a screen and a cleaning device as described in the above embodiment.

[0082] It can be understood that, due to the use of the cleaning device of the above embodiment, the automobile of the present application has the same technical effects as the above embodiment, which will not be described in detail here.

[0083] In the embodiment of the present application, the automobile may use an engine as a power source, or may use the motor 11 as a power source.

[0084] The third aspect of the present application provides a cleaning method, such as Figure 4 As shown, the cleaning method is applied to the automobile as in the above embodiment, and specifically includes:

[0085] 100: receiving a cleaning signal, and controlling the driving component 1 to drive the cleaning component 2 to move back and forth according to the cleaning signal through the MCU, until a stop signal is received or the number of reciprocating movements of the cleaning component 2 reaches a set number of times.

[0086] It can be understood that the cleaning signal can enable the car to understand when the screen needs to be cleaned. During cleaning, the cleaning effect is determined by the MCU or the number of reciprocating movements, which helps to keep the screen clean and reduce fingerprint residue.

[0087] In the embodiment of the present application, fingerprints are generally residual grease, and the impact of fingerprints on the screen display effect can be determined by detecting the capacitance of the screen surface. For example, a standard capacitance value can be set, and if a large difference is detected between the capacitance value of the screen and the standard capacitance value, a cleaning signal can be transmitted to the MCU, otherwise a stop signal can be transmitted to the MCU.

[0088] In an embodiment of the present application, before the number of reciprocating movements of the cleaning component 2 reaches a set number, it is possible to determine whether the cleaning component 2 can stop in the above manner, and transmit a stop signal to the MCU after determining that it can stop. In this way, the movement of the cleaning component 2 can be stopped in advance to reduce the interference of the working cleaning component 2 with the user's vision.

[0089] In the embodiment of the present application, the start switch of the cleaning component 2 is first pressed. After receiving the cleaning signal, the motor 11 starts to rotate in a clockwise direction. The rotation of the motor 11 drives the driving gear 12 to rotate. The rotating driving gear 12 drives the conveyor belt 14 to move, converting the rotation into a linear motion. At this time, the cleaning component 2 starts to move from one side to the opposite side along the length direction of the display screen for cleaning. In order to make the cleaning roller 23 fully contact the display screen, the cleaning component 2 will be higher than the display screen by a certain distance. After contacting the display screen, it will be squeezed and affected by the internal reset force, so that the roller 23 will be in full contact with the display screen, thereby achieving the effect of fully cleaning the display screen.

[0090] When the cleaning component 2 moves to the opposite side of the conveyor belt 14, the slider 211 on the connecting rod 21 will touch the spring 42 and apply a force to the spring 42. At this time, the force value is transmitted to the pressure sensor 41 through the spring 42. After the force value received by the pressure sensor 41 reaches a certain size, it will give feedback to the driving component 1. The driving component 1 receives feedback at this time and releases a reverse rotation signal to the motor 11. At this time, the motor 11 receives the signal and starts to rotate counterclockwise, driving the conveyor belt 14 to start moving and converting the rotation into linear motion. At this time, the cleaning component 2 starts to move and clean from the opposite side to one side along the length direction of the display screen. When the cleaning component 2 walks to one side, the slider 211 on the connecting rod 21 will touch the spring 42 and apply a force to the spring 42. At this time, the force is transmitted to the pressure sensor 41 connected to it through the spring 42. After the force value received by the sensor reaches a certain size, it will give feedback to the driving component 1. The driving component 1 receives feedback at this time and releases a reverse rotation signal to the motor 11. At this time, the motor 11 receives the signal and starts to rotate clockwise.

[0091] Ten such back-and-forth movements constitute a working cycle, and cleaning is completed after the cycle is completed. After pressing the stop cleaning button, the cleaning component 2 moves to the right and resets. The right pressure sensor 41 needs to sense the force value at this time and report it to the driving component 1. After receiving the stop cleaning command, the motor 11 is no longer sent a reverse command, and after the force value of the pressure sensor 41 reaches a certain value, the motor 11 is sent a stop working command, and the cleaning component 2 is automatically reset.

[0092] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
