Description

Technical Field

[0001] This application belongs to the technical field of intelligent household appliance design, and particularly relates to a cleaning robot. Background Art

[0002] The application of cleaning robots in people's daily lives is becoming more and more popular. A cleaning robot (such as a floor cleaning robot) can replace manual labor to clean the ground. Among them, the cleaning robot is prone to collide with walls, furniture, etc. during operation. In order to reduce the damage to the walls, furniture and the cleaning robot itself caused by these collisions, the edge of the housing of the cleaning robot is usually an arc edge.

[0003] However, the cleaning robot is prone to encounter corner areas such as wall corners and cabinet corners during operation. Due to the limitation of the arc edge of the housing of the cleaning robot, it is difficult for the cleaning robot to reach these corner areas, and it is difficult to clean these corner areas, which results in dead corners in the cleaning of the cleaning robot. Utility Model Content

[0004] The utility model discloses a cleaning robot to solve the problem of dead corners in the cleaning of the cleaning robot involved in the related art.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] This application discloses a cleaning robot, which includes a housing, a driving mechanism and a cleaning mechanism;

[0007] The driving mechanism and the cleaning mechanism are both arranged in the housing, and the cleaning mechanism is movably connected to the housing. The driving mechanism is connected to the cleaning mechanism to drive the cleaning mechanism to move so that the cleaning mechanism can switch between a first position and a second position;

[0008] When the cleaning mechanism is in the first position, the distance between the point farthest from the housing in the cleaning area of the cleaning mechanism and the housing is a first distance;

[0009] When the cleaning mechanism is in the second position, the distance between the point farthest from the housing in the cleaning area of the cleaning mechanism and the housing is a second distance;

[0010] The second distance is greater than the first distance.

[0011] The technical solution adopted by the utility model can achieve the following technical effects:

[0012] The cleaning robot disclosed in the embodiments of the present application improves the structure of the cleaning robot involved in the related art. By arranging the cleaning mechanism to be movably connected to the housing, and arranging the driving mechanism to be connected to the cleaning mechanism, the driving mechanism can drive the cleaning mechanism to move, so that the cleaning mechanism can switch between the first position and the second position. Thus, when the cleaning mechanism is in the first position, the distance between the point farthest from the housing in the cleaning area of the cleaning mechanism and the housing is the first distance, and when the cleaning mechanism is in the second position, the distance between the point farthest from the housing in the cleaning area of the cleaning mechanism and the housing is the second distance. By setting the second distance to be greater than the first distance, the cleaning area of the cleaning mechanism can be extended by switching the position of the cleaning mechanism, so that when facing corner areas such as wall corners and cabinet corners, the cleaning area of the cleaning mechanism can be extended by switching the cleaning mechanism to the second position, so as to realize the cleaning of the above-mentioned corner areas and alleviate the problem of cleaning dead corners existing in the cleaning robot.

[0032] Please refer to Figures 1 to 8, embodiments of the present application disclose a cleaning robot, which includes a housing 100, a driving mechanism 200, and a cleaning mechanism 300.

[0033] The housing 100 is a basic component of the cleaning robot, which is used to provide an installation position for other components of the cleaning robot. Among them, both the driving mechanism 200 and the cleaning mechanism 300 are arranged in the housing 100. In addition, the housing 100 is also used to form some functional spaces or structures, such as the first strip-shaped hole 110 and the second strip-shaped hole 120 described later.

[0034] The driving mechanism 200 is the core component that drives the movement of the cleaning mechanism 300 in the cleaning robot, and the cleaning mechanism 300 is the core component that realizes the cleaning function in the cleaning robot. The cleaning mechanism 300 is movably connected to the housing 100 so that the cleaning mechanism 300 can move relative to the housing 100. The driving mechanism 200 is connected to the cleaning mechanism 300 and is used to drive the cleaning mechanism 300 to move so that the cleaning mechanism 300 can switch between a first position and a second position.

[0035] In the specific working process, as Figure 1 , Figure 4 and Figure 5 shown, when the cleaning mechanism 300 is in the first position, the distance between the point farthest from the housing 100 in the cleaning area of the cleaning mechanism 300 and the housing 100 is the first distance. As Figure 2 , Figure 6 and Figure 7 shown, when the cleaning mechanism 300 is in the second position, the distance between the point farthest from the housing 100 in the cleaning area of the cleaning mechanism 300 and the housing 100 is the second distance. Among them, the second distance is greater than the first distance, so that when the cleaning mechanism 300 is in the second position, the distance between the point farthest from the housing 100 in the cleaning area and the housing 100 is farther, thereby extending the cleaning area of the cleaning mechanism 300, expanding the cleaning range of the cleaning robot, and further realizing the cleaning of corner areas such as the corners of walls and cabinets by the cleaning robot.

[0036] Optionally, the cleaning component 310 described hereinafter can be rotatably arranged on the second transmission member 320 described hereinafter. By rotating the cleaning component 310 relative to the second transmission member 320, a cleaning area can be formed. Exactly speaking, the cleaning area is essentially a circular area. During the process of the cleaning robot moving for cleaning, the cleaning component 310 rotates itself to rotate relative to the second transmission member 320, so as to achieve cleaning. It should be noted that the rotation axis of the cleaning component 310 does not coincide with the rotation axis of the second transmission member 320 and the rotation axis of the cleaning mechanism 300 respectively. Specifically, the cleaning component 310 can include a strip-shaped cleaning brush or an annular cleaning brush. In the case where the cleaning component 310 includes a strip-shaped cleaning brush, in order to improve the cleaning efficiency, there can be multiple strip-shaped cleaning brushes.

[0037] The cleaning robot disclosed in the embodiment of the present application improves the structure of the cleaning robot involved in the related technology. By arranging the cleaning mechanism 300 to be movably connected to the housing 100, and by arranging the driving mechanism 200 to be connected to the cleaning mechanism 300, the driving mechanism 200 can drive the cleaning mechanism 300 to move, so that the cleaning mechanism 300 can switch between the first position and the second position. Thus, when the cleaning mechanism 300 is in the first position, the distance between the point farthest from the housing 100 in the cleaning area of the cleaning mechanism 300 and the housing 100 is the first distance, and when the cleaning mechanism 300 is in the second position, the distance between the point farthest from the housing 100 in the cleaning area of the cleaning mechanism 300 and the housing is the second distance. By setting the second distance to be greater than the first distance, the cleaning area of the cleaning mechanism 300 can be extended by switching the position of the cleaning mechanism 300. When facing corner areas such as the corner of a wall or a cabinet, the cleaning area of the cleaning mechanism 300 can be extended by switching the cleaning mechanism 300 to the second position, so as to clean the above-mentioned corner areas and alleviate the problem of cleaning dead corners existing in the cleaning robot.

[0038] In a feasible embodiment, the cleaning mechanism 300 can be rotatably connected to the housing 100, so that the cleaning mechanism 300 can rotate relative to the housing 100. The driving mechanism 200 can be used to drive the cleaning mechanism 300 to rotate, so that the cleaning mechanism 300 can switch between the first position and the second position. In this case, the driving mechanism 200 can be a gear transmission mechanism, a belt transmission mechanism, a stepper motor or a servo motor.

[0039] Of course, the driving mechanism 200 can drive the cleaning mechanism 300 to move linearly, enabling the cleaning mechanism 300 to switch between the first position and the second position. Specifically, the driving mechanism 200 can drive the cleaning mechanism 300 to expand and contract. In this case, the driving mechanism 200 can be a hydraulic cylinder, a pneumatic cylinder, a linear motor, or a rack and pinion mechanism. It should be emphasized that the embodiments of the present invention do not limit the specific structure of the driving mechanism 200. Correspondingly, they do not limit the specific connection structure between the driving mechanism 200 and the cleaning mechanism 300, nor the specific movement mode when the cleaning mechanism 300 switches between the first position and the second position.

[0040] In a further technical solution, the driving mechanism 200 can include a power source 210 and a first transmission member 220 connected to each other. The power source 210 can be disposed in the housing 100. The power source 210 can provide power for the first transmission member 220 to drive the first transmission member 220 to rotate. The cleaning mechanism 300 can include a cleaning assembly 310 and a second transmission member 320 connected to each other. The second transmission member 320 can be disposed in the housing 100. The first transmission member 220 and the second transmission member 320 can be in transmission connection so that the first transmission member 220 can drive the second transmission member 320 to rotate, thereby enabling the first transmission member 220 to drive the cleaning assembly 310 to rotate around the rotation axis of the second transmission member 320 through the second transmission member 320, so as to switch the cleaning mechanism 300 between the first position and the second position. Among them, the rotation axis of the second transmission member 320 coincides with the rotation axis of the cleaning mechanism 300. Specifically, the power source 210 can be a motor.

[0041] In one embodiment, the first transmission member 220 can include a first meshing tooth 221, and the second transmission member 320 can include a second meshing tooth 321. The first transmission member 220 and the second transmission member 320 can be in transmission connection through the meshing of the first meshing tooth 221 and the second meshing tooth 321. Specifically, the first transmission member 220 and the second transmission member 320 can be a first gear and a second gear respectively. Of course, in order to save manufacturing costs and facilitate the miniaturization of the cleaning robot, the second gear can be a sector gear. This structure has high transmission efficiency, simple design, and is durable, and at the same time can achieve relatively precise speed and position control.

[0042] In another embodiment, the first transmission member 220 can be a first pulley, and the second transmission member 320 can be a second pulley. The cleaning robot can also include a transmission belt. The first pulley and the second pulley can be in transmission connection through the transmission belt. In this structure, the transmission belt has a good buffering effect, can absorb vibration and shock. When the load is too large, the transmission belt may slip, thus preventing damage to other transmission components. At the same time, this structure runs with less noise, which is beneficial to improving the user experience.

[0043] In other embodiments, the first transmission member 220 may be a first sprocket, the second transmission member 320 may be a second sprocket, and the cleaning robot may further include a transmission chain. The first sprocket and the second sprocket may be drivingly connected through the transmission chain. Such a structure can work in an environment with dust, high humidity or high temperature, so that the cleaning robot can adapt to a relatively complex environment.

[0044] In the embodiments of the present utility model, the driving mechanism 200 and the housing 100 may be movably connected or fixedly connected. Whether in the embodiment where the driving mechanism 200 and the housing 100 are movably connected or in the embodiment where the driving mechanism 200 and the housing 100 are fixedly connected, the driving mechanism 200 can drive the cleaning mechanism 300 to rotate relative to the housing 100, so that the cleaning mechanism 300 can normally switch between the first position and the second position.

[0045] In a feasible technical solution, the driving mechanism 200 may be movably disposed in the housing 100, and the driving mechanism 200 can drive the cleaning mechanism 300 to rotate about the rotation axis of the cleaning mechanism 300 along a first direction. Wherein, when the cleaning mechanism 300 is in the first position, the driving mechanism 200 no longer drives the cleaning mechanism 300 to rotate (for example, the driving mechanism 200 is turned off). That is, in this case, the driving connection between the driving mechanism 200 and the cleaning mechanism 300 enables the cleaning mechanism 300 to be maintained in the first position. At the same time, when the cleaning mechanism 300 is in the second position, the driving mechanism 200 no longer drives the cleaning mechanism 300 to rotate (for example, the driving mechanism 200 is turned off). That is, in this case, the driving connection between the driving mechanism 200 and the cleaning mechanism 300 enables the cleaning mechanism 300 to be maintained in the second position. It can be seen that the driving mechanism 200 may be a driving mechanism with a self-locking function.

[0046] Optionally, when the power source 210 is a motor, the first transmission member 220 includes a first engaging tooth 221, and the second transmission member 320 includes a second engaging tooth 321, when the cleaning mechanism 300 is in the first position and the second position, the motor can be in a locked state, so as to no longer drive the first transmission member 220 to rotate, thereby avoiding the first transmission member 220 driving the second transmission member 320 to rotate, and also avoiding the second transmission member 320 driving the motor to rotate through the first transmission member 220, so that the cleaning mechanism 300 can be maintained in the first position or the second position.

[0047] When the cleaning mechanism 300 is in the second position, the cleaning mechanism 300 extends out of the housing 100, so that the cleaning mechanism 300 is easily hit during the movement of the cleaning robot, so that the hit cleaning mechanism 300 switches to the first position. As Figure 8As shown, when the cleaning mechanism 300 at the second position is impacted by an external force and switches to the first position, the driving connection between the driving mechanism 200 and the cleaning mechanism 300 enables the cleaning mechanism 300 to drive the driving mechanism 200 to rotate around the rotation axis of the cleaning mechanism 300 along the second direction, so as to avoid the object hitting the cleaning mechanism 300 and prevent the cleaning mechanism 300 from being continuously impacted and easily damaged. The first direction may be opposite to the second direction.

[0048] Furthermore, the housing 100 may have a first strip-shaped hole 110, and the driving mechanism 200 and the first strip-shaped hole 110 may be slidably engaged, enabling the driving mechanism 200 to slide in the first strip-shaped hole 110, so as to provide a movement space for the driving mechanism 200 when the driving mechanism 200 rotates around the rotation axis of the cleaning mechanism 300 and avoid hindering the movement of the driving mechanism 200. At the same time, the driving mechanism 200 may be used to be respectively in limit fit with the first end of the first strip-shaped hole 110 and the second end of the first strip-shaped hole 110 to limit the rotation angle of the driving mechanism 200 around the rotation axis of the cleaning mechanism 300.

[0049] In the specific working process, when the cleaning mechanism 300 at the second position is impacted by an external force and switches to the first position, the cleaning mechanism 300 can drive the driving mechanism 200 to rotate around the rotation axis of the cleaning mechanism 300 along the second direction, so that the driving mechanism 200 slides from the first end of the first strip-shaped hole 110 to the second end of the first strip-shaped hole 110, that is, the second direction may be the direction from the first end of the first strip-shaped hole 110 towards the second end of the first strip-shaped hole 110. Correspondingly, the first direction may be the direction in which the second end of the first strip-shaped hole 110 extends towards the first end of the first strip-shaped hole 110.

[0050] The first strip-shaped hole 110 may also be a strip-shaped hole with a sufficiently large inner space, as long as it does not hinder the sliding of the driving mechanism 200. The specific shape of the first strip-shaped hole 110 is not limited in the embodiment of the present utility model. Preferably, the first strip-shaped hole 110 may be a first arc-shaped hole, and the center of the first arc-shaped hole may be on the rotation axis of the cleaning mechanism 300, so that when the cleaning mechanism 300 drives the driving mechanism 200 to rotate around the rotation axis of the cleaning mechanism 300 along the second direction, the driving mechanism 200 can slide more smoothly along the first arc-shaped hole, and the first arc-shaped hole can better guide the driving mechanism 200, thereby being beneficial to improving the movement stability of the driving mechanism 200.

[0051] To improve the driving stability of the driving mechanism 200, the cleaning robot may further include an elastic member 400. The first end of the elastic member 400 may be connected to the housing 100, and the second end of the elastic member 400 may be connected to the driving mechanism 200, so as to elastically abut the driving mechanism 200 against the first end of the first strip-shaped hole 110. Thus, when the cleaning mechanism 300 is in the first position or the second position and is not interfered by an external force, the elastic member 400 can maintain the driving mechanism 200 at the first end of the first strip-shaped hole 110, so that the driving mechanism 200 can always be in a position where it can drive the cleaning mechanism 300 to switch positions. Specifically, the elastic member 400 may be a spring (such as a torsion spring) or a rubber elastic member. The specific type of the elastic member 400 is not limited in the embodiments of the present application.

[0052] When the cleaning mechanism 300 in the second position is impacted by an external force and switches to the first position, the elastic member 400 can deform, so as to buffer the impact force received by the cleaning mechanism 300 through the elastic member 400. At the same time, the deformation recovery of the elastic member 400 enables the driving mechanism 200 to reset from the second end of the first strip-shaped hole 110 to the first end of the first strip-shaped hole 110, thereby realizing the automatic reset of the driving mechanism 200, which is beneficial to improving the automation degree of the cleaning robot and improving the working efficiency of the cleaning robot.

[0053] In the specific working process, when the cleaning mechanism 300 is in the first position or the second position and is not interfered by an external force, the elastic member 400 can maintain the driving mechanism 200 at the first end of the first strip-shaped hole 110. When the cleaning mechanism 300 in the second position is impacted by an external force, it will switch to the first position, which causes the driving mechanism 200 to first slide from the first end of the first strip-shaped hole 110 towards the second end of the first strip-shaped hole 110, thereby deforming the elastic member 400. After the impact ends, the elastic member 400 recovers from the deformation. Under the action of the restoring force of the elastic member 400, the elastic member 400 can drive the driving mechanism 200 to reset from the second end of the first strip-shaped hole 110 to the first end of the first strip-shaped hole 110.

[0054] In other embodiments, the cleaning robot may also include a manual operation part. The manual operation part may be connected to the driving mechanism 200, so that the driving mechanism 200 can be manually reset to the first end of the first strip-shaped hole 110 through the manual operation part. This structure is relatively simple and easy to implement, which is beneficial to reducing costs.

[0055] In an embodiment of the present application, the cleaning robot may further include a mounting bracket 500, which may have a mounting hole 510, a first mounting groove 520, and a second mounting groove 530. The driving mechanism 200 may be fixed in the mounting hole 510, and a partial structure of the cleaning mechanism 300 may be rotatably disposed in the first mounting groove 520. The first mounting groove 520 may communicate with the mounting hole 510 so that the driving mechanism 200 can be in transmission connection with the cleaning mechanism 300. The elastic member 400 may be disposed in the second mounting groove 530, and the second end of the elastic member 400 may be connected to the mounting bracket 500 to indirectly connect the driving mechanism 200 through the mounting bracket 500. The mounting bracket 500 may be rotatably disposed in the housing 100, and the rotation axis of the mounting bracket 500 may coincide with the rotation axis of the cleaning mechanism 300 so that the driving mechanism 200 can rotate around the rotation axis of the cleaning mechanism 300.

[0056] In a specific working process, since the first end of the elastic member 400 is connected to the housing 100 and the second end of the elastic member 400 is indirectly connected to the driving mechanism 200 through the mounting bracket 500, when the cleaning mechanism 300 is in the first position or the second position and is not disturbed by an external force, the elastic member 400 can maintain the driving mechanism 200 at the first end of the first elongated hole 110 through the mounting bracket 500. When the cleaning mechanism 300 in the second position is impacted by an external force and switches to the first position, the elastic member 400 in a compressed state deforms, and then can cause the driving mechanism 200 to reset from the second end of the first elongated hole 110 to the first end of the first elongated hole 110 through the mounting bracket 500.

[0057] Specifically, when the cleaning mechanism 300 in the second position is impacted by an external force, it will switch to the first position, which causes the driving mechanism 200 to first slide from the first end of the first elongated hole 110 towards the second end of the first elongated hole 110, thereby deforming the elastic member 400. After the impact ends, the deformation of the elastic member 400 recovers, and under the action of the restoring force of the elastic member 400, the elastic member 400 can drive the driving mechanism 200 to reset from the second end of the first elongated hole 110 to the first end of the first elongated hole 110 through the mounting bracket 500.

[0058] In a further technical solution, the cleaning robot may further include a fixing cover 600. The fixing cover 600 may cover the notch of the second installation groove 530 and may be fixedly connected to the housing 100. The side wall of the fixing cover 600 opposite to the notch of the second installation groove 530 may have a positioning hole 610. The first end of the elastic member 400 may be disposed in the positioning hole 610 so that the first end of the elastic member 400 is connected to the fixing cover 600, thereby enabling the first end of the elastic member 400 to be indirectly connected to the housing 100 through the fixing cover 600. The side wall of the second installation groove 530 may have a clamping groove 531. The second end of the elastic member 400 may be disposed in the clamping groove 531, so that the second end of the elastic member 400 is connected to the mounting bracket 500 to indirectly connect the driving mechanism 200 through the mounting bracket 500. Of course, the first end of the elastic member 400 may also be directly fixed to the housing 100 by means such as welding and bonding, and the second end of the elastic member 400 may be connected to the mounting bracket 500 by means such as welding and bonding. The embodiments of the present utility model do not limit this.

[0059] In the specific working process, since the first end of the elastic member 400 is indirectly connected to the housing 100 through the fixing cover 600, and the second end of the elastic member 400 is indirectly connected to the driving mechanism 200 through the mounting bracket 500, when the cleaning mechanism 300 is in the first position or the second position and is not interfered by external forces, the elastic member 400 can maintain the driving mechanism 200 at the first end of the first elongated hole 110 through the mounting bracket 500. When the cleaning mechanism 300 in the second position is impacted by an external force and switches to the first position, the elastic member 400 in the compressed state can enable the driving mechanism 200 to reset from the second end of the first elongated hole 110 to the first end of the first elongated hole 110 through the mounting bracket 500.

[0060] Specifically, when the cleaning mechanism 300 in the second position is impacted by an external force, it will switch to the first position, which causes the driving mechanism 200 to first slide from the first end of the first elongated hole 110 towards the second end of the first elongated hole 110, thereby causing the elastic member 400 to deform. After the impact ends, the deformation of the elastic member 400 is restored. Under the action of the restoring force of the elastic member 400, the elastic member 400 can drive the driving mechanism 200 to reset from the second end of the first elongated hole 110 to the first end of the first elongated hole 110.

[0061] To improve the reliability of the elastic member 400, the bottom wall of the second installation groove 530 may have a mounting protrusion 532. The elastic member 400 may be sleeved on the mounting protrusion 532 to prevent the elastic member 400 from being easily displaced when compressed and making it difficult to stably drive the driving mechanism 200 to reset to the first end of the first elongated hole 110.

[0062] In an alternative technical solution, the cleaning robot may further include a connecting shaft 710 and a connecting member 720. The connecting shaft 710 may sequentially pass through the first mounting groove 520, the second transmission member 320 in the first mounting groove 520, the bottom wall of the second mounting groove 530, and the mounting protrusion 532, and be connected to the connecting member 720 passing through the fixing cover 600, so that the mounting bracket 500 can rotate around the central axis of the connecting shaft 710, enabling the driving mechanism 200 to rotate around the central axis of the connecting shaft 710 through the mounting bracket 500, and enabling the cleaning mechanism 300 to rotate around the central axis of the connecting shaft 710. The central axis of the connecting shaft 710 coincides with the rotation axis of the cleaning mechanism 300, so that the driving mechanism 200 can rotate around the rotation axis of the cleaning mechanism 300. Specifically, the connecting member 720 may be a screw or a bolt.

[0063] To prevent loosening of the connection between the connecting shaft 710 and the connecting member 720, the cleaning robot may further include a gasket 730. The connecting member 720 may pass through the gasket 730, and the gasket 730 may be disposed between the connecting member 720 and the fixing cover 600, making the connection between the connecting shaft 710 and the connecting member 720 more reliable. To further improve the reliability of the connection between the connecting shaft 710 and the connecting member 720, there may be multiple gaskets 730. Specifically, there may be two gaskets 730, which can effectively reduce the risk of loosening between the connecting shaft 710 and the connecting member 720 and avoid wasting gaskets 730 to save costs.

[0064] To improve the stability of the cleaning mechanism 300 when switching between the first position and the second position, the cleaning mechanism 300 may have a limiting protrusion 330, and the housing 100 may have a second elongated hole 120. The limiting protrusion 330 and the second elongated hole 120 may be in sliding fit, enabling the limiting protrusion 330 to slide in the second elongated hole 120 as the cleaning mechanism 300 switches between the first position and the second position, so that the limiting protrusion 330 can be stably switched to the first position or the second position under the guidance of the second elongated hole 120.

[0065] When the cleaning mechanism 300 is in the first position, the limiting protrusion 330 and the first end of the second elongated hole 120 may be in limiting fit. When the cleaning mechanism 300 is in the second position, the limiting protrusion 330 and the second end of the second elongated hole 120 may be in limiting fit, which can limit the rotation angle of the cleaning mechanism 300, prevent the cleaning mechanism 300 from rotating excessively and making it difficult to accurately rotate to the first position or the second position, and enable the cleaning mechanism 300 to stably rotate to the first position or the second position.

[0066] The second strip-shaped hole 120 can be a strip-shaped hole with a sufficiently large inner space as long as it does not hinder the sliding of the limit protrusion 330. The specific shape of the second strip-shaped hole 120 is not limited in the embodiments of the present invention. In a more preferred technical solution, the second strip-shaped hole 120 can be a second arc-shaped hole, and the center of the second arc-shaped hole can be on the rotation axis of the cleaning mechanism 300, so that the cleaning mechanism 300 can slide more smoothly along the second arc-shaped hole when rotating, which is beneficial to further improving the rotation stability of the cleaning mechanism 300.

[0067] In the embodiments of the present invention, the cleaning robot can be a floor sweeping robot or a washing robot, etc. The specific type of the cleaning robot is not limited in the embodiments of the present application.

[0068] In the above embodiments of the present invention, the differences between the embodiments are mainly described. As long as the different optimized features of the embodiments do not conflict, they can be combined to form a more optimal embodiment. For the sake of brevity of the description, they will not be elaborated here.

[0069] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the purpose of the present invention and the scope protected by the claims, and all of them fall within the protection scope of the present invention.
