[0028] See also Figure 1 , Figure 1 It is a schematic diagram of the local structure of the cleaning system 1000 provided in an embodiment of the utility model. The cleaning system 1000 includes a robot 200 and a charging device 300. The robot 200 may include but is not limited to a handheld, riding, and fully automatic intelligent walking device, etc., which is not limited by the utility model. The robot 200 can move on the ground. For example, the robot 200 can move on the ground under the push of the user. For another example, the robot 200 itself has the ability to move and can automatically move on the ground through a driving mechanism. The charging device 300 is used to be electrically connected to the robot 200, so that the charging device 300 charges the robot 200. In this embodiment, the robot 200 can be a lawn mower. Of course, in some embodiments, the robot 200 can also be but is not limited to a sweeper or other intelligent devices.

[0029] Exemplarily, in this embodiment, a sensor 210 is provided on the robot 200. The sensor 210 may be, but is not limited to, a distance sensor, a visual sensor, an ultrasonic sensor, and the like. For example, the sensor 210 may be used to detect the position information of the charging device 300, so as to facilitate the alignment charging of the robot 200 and the charging device 300. For another example, the sensor 210 may also be used to detect obstacles in the surrounding environment, so as to facilitate the safe driving of the robot 200. The type and function of the sensor 210 may be designed according to actual conditions, and the embodiment of the utility model does not make specific limitations. For example, the detection data of the sensor 210 may also be used for, but is not limited to, identifying boundaries, automatic navigation, and intelligently adapting to the working environment of the robot 200.

[0030] The charging device 300 includes a charging pile 310 and a cleaning mechanism 100. The cleaning mechanism 100 is installed on the charging pile 310. The cleaning mechanism 100 is used to clean the sensor 210 of the robot 200 to improve the sensing sensitivity and sensing accuracy of the sensor 210. As a result, when the robot 200 is docked with the charging pile 310, the problem of entanglement of the connecting cable is avoided, and the robot 200 and the charging pile 310 are automatically charged in position, without the need to manually connect the robot 200 to the charging pile 310, thereby improving the intelligent charging of the robot 200. Specifically, a charging terminal 330 is provided on the charging pile 310. The robot 200 is provided with a connecting terminal 230 that docks with the charging terminal 330, thereby realizing the plug-in charging of the robot 200 and the charging pile 310. The charging terminal 330 docks with the connecting terminal 230 along the plug-in direction F. By way of example, in this embodiment, the plug-in direction F is parallel to the horizontal plane.

[0031] In some embodiments, the charging terminal 330 and the cleaning mechanism 100 are arranged on the same side of the charging pile 310, and the connecting terminal 230 and the sensor 210 are arranged on the same side of the robot 200. Therefore, on the one hand, during the charging process of the robot 200 and the charging pile 310, the cleaning mechanism 100 can clean the sensor 210 of the robot 200, which increases the structural diversity and functionality of the charging device 300; on the other hand, the alignment of the cleaning mechanism 100 and the sensor 210 is achieved through the alignment charging of the robot 200 and the charging pile 310, so that there is no need to set an additional positioning structure on the charging pile 310 or the robot 200 to position the cleaning mechanism 100 and the sensor 210, which simplifies the overall structure of the charging device 300 and improves the cleaning quality of the cleaning mechanism 100.

[0032] Exemplarily, in this embodiment, the connection terminal 230 and the sensor 210 are both disposed at the tail of the robot 200, so as to facilitate alignment of the sensor 210 with the cleaning mechanism 100. More specifically, when the robot 200 is charged with the charging pile 310, the mirror surface of the sensor 210 faces the cleaning mechanism 100 disposed on the charging pile 310, so as to facilitate the cleaning mechanism 100 to clean the mirror surface of the sensor 210.

[0033] In some embodiments, the charging terminal 330 is rotatably connected to the charging pile 310. Thus, when the robot 200 is not facing the charging pile 310, that is, the charging terminal 330 is not completely aligned with the connecting terminal 230, since the charging terminal 330 provided on the charging pile 310 is rotatable, the charging terminal 330 and the connecting terminal 230 can be docked even when there is a certain angle deviation between the robot 200 and the charging pile 310. The charging terminal 330 is configured as a long strip terminal. It can be understood that the rotation angle of the charging terminal 330 relative to the charging pile 310 can be limited to a certain range to realize the plug-in charging function between the robot 200 and the charging pile 310. The rotation angle can be set according to factors such as the structure and size of the connecting terminal 230 of the robot 200 or the structure and size of the charging terminal 330, and the utility model does not make specific restrictions.

[0034] Exemplarily, in this embodiment, one or more sensors 210 are provided on the robot 200. A plurality of cleaning mechanisms 100 are provided on the charging pile 310, and the plurality of cleaning mechanisms 100 are used to be arranged one-to-one with the plurality of sensors 210 on the robot 200, so that the mirror surface of each sensor 210 can be cleaned by the corresponding cleaning mechanism 100, thereby improving the sensing sensitivity and sensing accuracy of each sensor 210. Of course, in some embodiments, a plurality of cleaning mechanisms 100 are used to be arranged corresponding to a sensor 210 provided on the robot 200. In other embodiments, only one cleaning mechanism 100 may be provided on the charging pile 310. A cleaning mechanism 100 is used to be arranged corresponding to a plurality of sensors 210 on the robot 200, so that a cleaning mechanism 100 cleans the mirror surface of a plurality of sensors 210. It can be understood that the number of cleaning mechanisms 100 and the number of sensors 210 may be the same or different, and the number of cleaning mechanisms 100 may be set according to factors such as the setting position of the sensor 210 or the size of the sensor 210, and the embodiment of the utility model is not specifically limited.

[0035] In some embodiments, the robot 200 is further provided with a protective cover 220. The protective cover 220 covers the sensor 210 and is arranged to protrude relative to the sensor 210. Thus, on the one hand, the sensor 210 is prevented from being damaged by exposure to rain or sunlight; on the other hand, the protective cover 220 can also limit the cleaning mechanism 100, thereby preventing the cleaning mechanism 100 from deviating from the sensor 210 and improving the cleaning effect of the cleaning mechanism 100.

[0036] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement of the cleaning mechanism 100, the charging pile 310 and the robot 200, and it is not to make specific limitations on the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the cleaning system 1000 is only shown in the embodiment of the present invention, and does not constitute a specific limitation on the robot 200. In other embodiments of the present invention, the robot 200 may include Figure 1 More or fewer components as shown, or a combination of certain components, or different components, for example, the cleaning system 1000 may also include but is not limited to a charging metering structure, a safety protection structure, and the like.

[0037] Please also read Figure 1 and Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the structure of the cleaning mechanism 100 of the cleaning system 1000 in the figure. The first embodiment of the utility model provides a cleaning mechanism 100. The cleaning mechanism 100 is installed on a charging pile 310. The cleaning mechanism 100 includes a shell 10 and a cleaning brush 30. The shell 10 is fixed on the charging pile 310. The cleaning brush 30 includes a brush rod 31 and a brush head 32. One end of the brush rod 31 is connected to the brush head 32, and the other end of the brush rod 31 is rotatably connected to the shell 10. The rotation of the brush rod 31 can drive the brush head 32 to rotate, and the brush head 32 is used to abut against the sensor 210.

[0038] The cleaning mechanism 100 provided by the utility model is based on that the cleaning mechanism 100 is arranged on the charging pile 310, and the cleaning mechanism 100 includes a shell 10 and a cleaning brush 30, and the cleaning brush 30 includes a brush rod 31 and a brush head 32. On the one hand, the brush head 32 can abut against the sensor 210 to clean the sensor 210, thereby improving the sensing sensitivity and sensing accuracy of the sensor 210; on the other hand, one end of the brush rod 31 is connected to the brush head 32, and the brush rod 31 can drive the brush head 32 to rotate, thereby improving the cleaning effect of the brush head 32 on the sensor 210; on the other hand, the cleaning brush 30 is installed on the charging pile 310 through the shell 10, thereby facilitating the installation and maintenance of the cleaning mechanism 100.

[0039] For example, in this embodiment, the housing 10 is configured as a cylindrical structure. Of course, in a possible implementation, the housing 10 can also be configured as a prismatic structure. Specifically, the cross section of the housing 10 along the radial direction X can be, but is not limited to, rectangular, circular, elliptical or polygonal. For the accuracy of the description, all directions in this document shall be referred to as Figure 2For reference, the term "radial X" refers to the direction perpendicular to the central axis P of the cleaning mechanism 100, that is, the radial direction along the cross section of the cleaning mechanism 100. The central axis P of the cleaning mechanism 100 is parallel to the plug-in direction F. The term "axial Y" refers to the direction parallel to the central axis P of the cleaning mechanism 100. The term "circumferential Z" refers to the circumferential direction of the cleaning mechanism 100, that is, the direction surrounding the central axis P of the cleaning mechanism 100, wherein the radial X, axial Y and circumferential Z together constitute the three orthogonal directions of the cleaning mechanism 100. The radial X, axial Y and circumferential Z of the cleaning mechanism 100 can be customized according to the specific structure of the product and the perspective of the drawings, and the utility model does not make specific limitations.

[0040] In this embodiment, the housing 10 is detachably mounted on the charging pile 310, so as to facilitate operations such as cleaning, replacement or maintenance of the cleaning brush 30, and can be removed from the charging pile 310 when the cleaning mechanism 100 is not in use, thus enriching the application scenarios of the charging pile 310. Of course, in some embodiments, the housing 10 can be non-detachably connected to the charging pile 310, thereby improving the reliability and stability of the connection between the housing 10 and the charging pile 310.

[0041] One or more cleaning brushes 30 may be installed on the housing 10. Exemplarily, in this embodiment, one cleaning brush 30 is installed on the housing 10, so that the cleaning brush 30 can be assembled on the housing 10. In some embodiments, multiple cleaning brushes 30 may be installed on the housing 10, so that multiple cleaning brushes 30 can clean multiple sensors 210, saving costs and realizing a miniaturized design of the cleaning mechanism 100. It should be noted that the housing 10 of the cleaning mechanism 100 can be used as a part of the housing of the charging pile 310; or, the housing 10 of the cleaning mechanism 100 and the housing 10 of the charging pile 310 are independent of each other and fixedly connected.

[0042] Please also read Figure 1 and Figure 3 , Figure 3 yes Figure 2 Exploded view of the cleaning mechanism in . Exemplarily, in the present embodiment, the brush rod 31 is fixedly connected to the brush head 32. Thus, the rotation of the brush rod 31 can drive the brush head 32 to rotate synchronously, so as to achieve the cleaning effect of the brush head 32 on the mirror surface of the sensor 210. In some embodiments, the brush rod 31 is rotatably connected to the brush head 32. Specifically, the brush rod 31 is rotatably connected to the brush head 32 via a ball head structure. Thus, when the robot 200 and the charging pile 310 are plugged in and charged with an angle deviation, the brush head 32 can rotate relative to the brush rod 31, so that the brush surface of the brush head 32 can still fit the mirror surface of the sensor 210, thereby improving the cleaning quality of the cleaning structure.

[0043] The brush head 32 is detachably connected to the brush rod 31, so as to facilitate the cleaning or replacement of the brush head 32. Specifically, the cleaning brush 30 also includes a brush head seat 33. The brush head seat 33 is fixed to one end of the brush rod 31. The brush head 32 is mounted on the brush head seat 33. The brush head 32 is detachably connected to the brush head seat 33; or, the brush head seat 33 is detachably connected to the brush rod 31. Of course, in some embodiments, the brush head 32 is non-detachably connected to the brush rod 31. The material of the brush head 32 may include but is not limited to cotton cloth, sponge, flexible fiber or other softer materials, thereby reducing the wear of the mirror surface of the sensor 210.

[0044] For example, in this embodiment, the brush rod 31 is configured as a screw rod, and the cleaning mechanism 100 further includes a screw nut 40, which is fixedly connected to the housing 10 and rotatably connected to the brush rod 31. Therefore, on the one hand, when the brush rod 31 moves along the axial direction Y of the cleaning mechanism 100 toward the side close to the charging pile 310 under the action of an external force, the brush rod 31 rotates relative to the housing 10 along the circumferential direction Z of the cleaning mechanism 100 under the action of the screw nut 40, thereby improving the cleaning effect of the brush head 32 on the lens; on the other hand, the brush rod 31 and the screw nut 40 are threadedly matched, thereby improving the stability of the rotation of the brush head 32 and avoiding the problem of the brush head 32 causing wear on the mirror surface of the sensor 210.

[0045] In some embodiments, when the cleaning mechanism 100 and the sensor 210 are first abutted, the charging terminal 330 and the connecting terminal 230 are spaced apart; when the charging terminal 330 and the connecting terminal 230 are completely docked, the brush head 32 and the sensor 210 are abutted, and the cleaning brush 30 is stationary relative to the housing 10. After the cleaning mechanism 100 and the sensor 210 are first abutted, before the charging terminal 330 and the connecting terminal 230 are completely docked, the brush head 32 and the sensor 210 are abutted, and the cleaning brush 30 rotates relative to the housing 10. Therefore, in the process of the robot 200 returning to the charging pile 310 for charging, the robot 200 will move toward the side close to the charging pile 310 and stop moving after the charging terminal 330 is completely docked with the connecting terminal 230. Since the cleaning mechanism 100 and the sensor 210 complete the initial contact before the charging terminal 330 and the connecting terminal 230 are completely docked, that is, after the cleaning mechanism 100 and the sensor 210 are initially abutted and before the charging terminal 330 and the connecting terminal 230 are completely docked, the robot 200 will still move toward the side close to the charging pile 310. Therefore, the sensor 210 of the robot 200 will apply a thrust to the cleaning mechanism 100, and the brush rod 31 moves relative to the screw nut 40 along the axial direction Y toward the side close to the charging pile 310 and rotates along the circumferential direction Z under the action of the thrust, and the rotation of the brush rod 31 will drive the brush head 32 to rotate, so as to clean the mirror surface of the sensor 210. Therefore, the cleaning mechanism 100 utilizes the threaded connection between the lead screw and the lead screw nut 40, and sets the stroke of the charging terminal 330 and the connecting terminal 230 to be greater than the stroke of the cleaning mechanism 100 and the sensor 210, so that the robot 200 reserves a stroke for the cleaning mechanism 100 and the sensor 210 to drive the brush head 32 of the cleaning brush 30 to rotate. On the one hand, the cleaning mechanism 100 does not need to set an additional drive motor to drive the brush rod 31 to drive the brush head 32 to rotate, and the structure is simple and the cost is low; on the other hand, after the charging terminal 330 and the connecting terminal 230 are docked, the robot 200 will stop moving toward the charging pile 310. At this time, the robot 200 cancels the thrust applied to the cleaning mechanism 100, so that the cleaning brush 30 stops cleaning the sensor 210, thereby avoiding the problem of wear caused by the cleaning brush 30 rubbing the mirror surface of the sensor 210 for a long time.

[0046] Of course, in some embodiments, the cleaning mechanism 100 may also include a drive motor. The drive motor is used to drive the brush rod 31 to drive the brush head 32 to rotate, so as to clean the mirror surface of the sensor 210. At this time, the brush rod 31 can be configured as a screw rod, or it can also be configured as a non-threaded rod. The drive motor is also used to stop driving the brush rod 31 to rotate after receiving the completion of docking between the charging terminal 330 and the connecting terminal 230, so that the cleaning brush 30 stops cleaning the sensor 210, avoiding the problem of wear caused by the cleaning brush 30 rubbing the mirror surface of the sensor 210 for a long time. It can be understood that the drive motor is also used to stop driving the brush rod 31 to rotate after receiving the completion of docking between the charging terminal 330 and the connecting terminal 230 for a preset time.

[0047] Please also read Figure 1 and Figures 3 to 5 , Figure 4 yes Figure 2 A bottom view of the cleaning mechanism in FIG. Figure 5 yes Figure 4 A cross-sectional view of the cleaning mechanism along line II in FIG. In some embodiments, the cleaning mechanism 100 further includes a reset member 50. One end of the reset member 50 elastically acts on the housing 10, and the other end of the reset member 50 elastically acts on the brush rod 31. The reset member 50 is used to drive the cleaning brush 30 to reset to the initial position. Thus, on the one hand, the reset member 50 can drive the cleaning brush 30 to the initial position, so as to facilitate the robot 200 to clean the sensor 210 when charging next time, with a simple structure and low cost; on the other hand, during the withdrawal of the robot 200 from the charging pile 310, the reset member 50 will drive the cleaning brush 30 to reset, and the brush rod 31 moves relative to the screw nut 40 along the axial direction Y toward the side facing away from the charging pile 310 and rotates along the circumferential direction Z under the action of the elastic force of the reset member 50, and the rotation of the brush rod 31 will drive the brush head 32 to rotate, thereby realizing the cleaning of the mirror surface of the sensor 210 again, and improving the cleaning quality of the sensor 210 by the cleaning mechanism 100.

[0048] Specifically, one end of the reset member 50 is arranged on the housing 10, and the other end of the reset member 50 is arranged on the brush rod 31, so that the reset member 50 can apply an elastic force to the housing 10 and the brush rod 31. For example, one end of the reset member 50 elastically abuts the housing 10, and the other end of the reset member 50 elastically abuts the brush rod 31; or, one end of the reset member 50 is elastically connected to the housing 10, and the other end of the reset member 50 is elastically connected to the brush rod 31; or, one end of the reset member 50 elastically abuts the housing 10, and the other end of the reset member 50 is elastically connected to the brush rod 31; or, one end of the reset member 50 elastically abuts the housing 10, and the other end of the reset member 50 is elastically connected to the brush rod 31. Exemplarily, in this embodiment, the reset member 50 is configured as a spring. Of course, in some embodiments, the reset member 50 can be configured as a spring, an elastic block or other elastic structure.

[0049] For example, in this embodiment, the housing 10 and the lead screw nut 40 form a receiving chamber 101. The reset member 50 is disposed in the receiving chamber 101 and elastically supported at one end of the lead screw facing away from the brush head 32. Thus, the reset member 50 is prevented from being exposed outside the receiving chamber 101 and easily causing wear and collision, thereby improving the aesthetics of the cleaning mechanism 100 and extending the service life of the cleaning mechanism 100.

[0050] Of course, in some embodiments, the cleaning mechanism 100 may not include the reset member 50, that is, the cleaning brush 30 is driven by the driving motor to achieve the reset function; or, the reset member 50 and the driving structure work together to achieve the reset of the cleaning brush 30; or, the user manually operates to achieve the reset of the cleaning brush 30. The reset of the cleaning brush 30 can be designed according to actual conditions, and the utility model does not make specific limitations.

[0051] Exemplarily, in the present embodiment, a positioning groove 102 connected to the accommodating chamber 101 is provided at one end of the housing 10 facing away from the charging pile 310. The screw nut 40 is installed in the positioning groove 102, thereby improving the assembly efficiency and assembly yield of the screw nut 40 and the housing 10. Specifically, a connecting hole is provided at the bottom of the positioning groove 102, and the accommodating chamber 101 is connected to the positioning groove 102 through a through hole 103. The screw nut 40 includes a nut body 41 and a mounting seat 42. The nut body 41 is threadedly engaged with the screw and is fixed to the housing 10 through the mounting seat 42. The nut body 41 is provided with a screw hole 401 that cooperates with the brush rod 31 along the axial direction Y. The screw hole 401 is connected to the accommodating chamber 101, so that the screw can extend into the accommodating chamber 101 after moving along the axial direction Y relative to the housing 10, so as to press the reset member 50 to cause the reset member 50 to undergo elastic deformation, and the structural layout is reasonable and compact.

[0052] The nut body 41 is inserted into the positioning groove 102 and the through hole 103, and is threadedly engaged with the brush rod 31, thereby extending the threaded distance between the nut body 41 and the brush rod 31, and improving the stability and reliability of the brush rod 31 moving relative to the screw nut 40 along the axial direction Y. The mounting seat 42 is fixedly connected to the nut body 41 and installed in the positioning groove 102, thereby realizing the fixed connection between the screw nut 40 and the housing 10. Of course, in some embodiments, the nut body 41 can be only accommodated in the positioning groove 102.

[0053] In some embodiments, the cleaning mechanism 100 further includes a transmission rod 61 and a pressing block 62, one end of the transmission rod 61 is arranged for transmission with the brush rod 31, the other end of the transmission rod 61 is movably arranged in the housing 10, the reset member 50 is sleeved on the transmission rod 61, and the pressing block 62 is fixed on the transmission rod 61 and is used to press the reset member 50. Therefore, on the one hand, the transmission rod 61 can guide the reset member 50, thereby improving the stability and reliability of the brush rod 31 moving along the axial direction Y relative to the screw nut 40; on the other hand, it is convenient to assemble the cleaning brush 30, the screw nut 40, the reset member 50, the transmission rod 61 and the housing 10.

[0054] In this embodiment, the pressing block 62 is fixed to one end of the transmission rod 61, and the transmission rod 61 is in contact with the brush rod 31 through the pressing block 62. Therefore, on the one hand, the assembly and maintenance of the pressing block 62 and the brush rod 31 are facilitated; on the other hand, since the brush rod 31 and the transmission rod 61 are rotationally matched, the transmission rod 61 only moves along the axial direction Y relative to the housing 10, thereby reducing the friction between the transmission rod 61 and the housing 10 and the reset member 50, reducing noise, and increasing the movement stroke of the transmission rod 61, which is convenient for the reset member 50 to drive the cleaning brush 30 to reset. Of course, in some embodiments, the transmission rod 61 can also be connected to the brush rod 31 through the pressing block 62. The pressing block 62 and the transmission rod 61 can be integrally formed, thereby improving the reliability of the connection between the pressing block 62 and the transmission rod 61. Of course, in some embodiments, the pressing block 62 and the transmission rod 61 are independent of each other and fixedly connected. The pressing block 62 and the transmission rod 61 can be fixedly connected by screwing, welding, clamping, gluing, etc., and the embodiment of the utility model is not specifically limited.

[0055] For example, in this embodiment, the transmission rod 61 and the brush rod 31 are coaxially arranged, thereby improving the transmission efficiency between the transmission rod 61 and the brush rod 31, improving the stability and reliability of the rotation of the brush rod 31, and reducing the number of parts of the cleaning mechanism 100, reducing the weight and volume of the cleaning mechanism 100, simplifying the structure and reducing costs. Of course, in some embodiments, the transmission rod 61 and the brush rod 31 can also be eccentrically arranged, so as to facilitate the adjustment of the rotation position of the brush head 32 to improve the cleaning effect and cleaning efficiency of the sensor 210.

[0056] In some embodiments, a limiting groove 6201 is provided at one end of the pressing block 62 facing away from the transmission rod 61. One end of the brush rod 31 facing away from the brush head 32 is accommodated in the limiting groove 6201, thereby improving the assembly efficiency and assembly yield, and improving the reliability of the rotation of the brush rod 31. The brush rod 31 and the limiting groove 6201 are clearance-matched, thereby avoiding the problem of interference between the brush rod 31 and the pressing block 62 during the rotation process, and improving the smoothness and reliability of the rotation of the brush rod 31.

[0057] The cleaning mechanism 100 also includes a guide seat 70 fixed on the shell 10, and the guide seat 70 is provided with a guide hole 701 that slides with the transmission rod 61; the reset member 50 elastically abuts between the pressure block 62 and the guide seat 70. On the one hand, it improves the guiding effect of the transmission rod 61 on the brush rod 31, ensures the alignment and fit of the brush head 32 and the mirror surface of the sensor 210, and improves the cleaning effect of the brush head 32 on the mirror surface of the sensor 210; on the other hand, it facilitates the assembly of the transmission rod 61 and the shell 10.

[0058] Exemplarily, in this embodiment, the guide seat 70 includes a mounting plate 71 and a guide sleeve 72. The guide sleeve 72 is sleeved on the transmission rod 61. The guide sleeve 72 is fixed to the housing 10 through the mounting plate 71. The housing 10 is further provided with a mounting groove 104 at one end facing away from the screw nut 40. The mounting plate 71 is installed in the mounting groove 104, thereby improving the assembly efficiency and assembly yield of the guide seat 70 and the housing 10.

[0059] In some embodiments, the housing 10 can be mounted on the charging pile 310 through the guide seat 70. In some other embodiments, the charging pile 310 can be provided with a fixing cavity for mounting the housing 10, thereby reducing the space occupied by the charging device 300. The fixed connection method between the housing 10 and the charging pile 310 can be designed according to actual conditions, and the embodiment of the utility model does not make specific limitations.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
