Detailed Implementation

[0045] The embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this disclosure.

[0046] It should be noted that in the embodiments of this disclosure, the orientations or positional relationships such as "upper" and "lower" are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientational terms are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. The disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of the embodiments of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure based on the specific circumstances.

[0048] In the description of this specification, references to terms such as "some embodiments," "exemplary," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the embodiments of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, those skilled in the art can combine the different embodiments or examples described in this disclosure and the features of those different embodiments or examples without contradiction.

[0049] In related technologies, the cleaning components of cleaning equipment remain in contact with the ground after the operation is completed. During the movement of the cleaning equipment, the cleaning components are prone to soiling the cleaned ground, and the cleaning components are prone to wear and tear when in contact with the ground when not in operation, which affects the service life.

[0050] In view of this, referring to Figures 1-3, this disclosure provides a cleaning module 100 that allows the cleaning component 12 to rise above the placement surface after its operation. The placement surface refers to the contact surface where the cleaning equipment is located when it is moving or stationary, such as the ground, hereinafter collectively referred to as the ground. The cleaning module 100 can be used in the cleaning equipment. Exemplarily, the cleaning equipment includes a main body for providing installation positions for various structures within the cleaning equipment. The outer shell structure of the main body can be square or disc-shaped, and the cleaning module 100 is disposed on the main body.

[0051] The cleaning module 100 can be used in cleaning equipment such as sweepers to clean up debris, including but not limited to hair, dust, and crumbs. The cleaning module 100 can be a side brush module or a main brush module. When the cleaning module 100 is a side brush module, the cleaning equipment can also be equipped with a main brush module; the cleaning module 100 can work in conjunction with the main brush module for individual or combined cleaning operations. The side brush module includes side brushes, whose rotation axis is generally set at an angle to the ground, such as 90 degrees or tilted at a certain angle to the vertical direction. The main brush module includes a main brush, whose rotation axis can be parallel to the ground, perpendicular to the ground, or tilted at a certain angle to the vertical direction.

[0052] The cleaning module 100 includes a cleaning component 10, a power component 20, and a lifting component 30. The cleaning component 10 includes a rotating housing 11 and a cleaning element 12. The power component 20 is drivenly connected to the cleaning component 10, for example, the power component 20 is drivenly connected to the rotating housing 11 to drive the rotating housing 11 to rotate. One end of the lifting component 30 is dampedly connected to the power component 20, and the other end of the lifting component 30 is helically connected to the rotating housing 11. One end of the cleaning element 12 is located inside the rotating housing 11 and fixedly connected to the lifting component 30, while the other end of the cleaning element 12 protrudes outside the rotating housing 11. The rotating housing 11 rotates along a first direction S, which can cause the lifting component 30 to descend to a first position, thereby lowering the cleaning element 12; the rotating housing 11 rotates along a second direction R, which can cause the lifting component 30 to rise to a second position, thereby raising the cleaning element 12. The first direction S and the second direction R are opposite. Vertically, the second position is higher than the first position.

[0053] A spiral connection refers to the lifting component 30 and the rotating housing 11 being connected by a spiral joint, such as a threaded joint, a spiral groove, or a protruding post joint; the cleaning component 10 is driven to rotate by the power component 20. For example, when the circumferential rotation of the lifting component 30 is not limited, the power component 20 drives the rotating housing 11 to rotate, and the lifting component 30 can move up and down relative to the rotating housing 11 in a spiral manner along the rotation axis of the rotating housing 11. When the circumferential rotation of the lifting component 30 is limited, the power component 20 drives the rotating housing 11 to rotate, and the lifting component 30 can move up and down relative to the rotating housing 11 in a linear manner along the rotation axis of the rotating housing 11.

[0054] Damping connection refers to the fact that when the power component 20 drives the rotating shell 11 to rotate, the power component 20 can apply a force to the lifting component 30 so that there is a speed difference between the speed of the lifting component 30 and the speed of the rotating shell 11. For example, the lifting component 30 stops rotating or its speed is lower than that of the rotating shell 11, so that the lifting component 30 can lift and lower under the action of the spiral connection with the rotating shell 11.

[0055] The method by which one end of the lifting member 30 is dampedly connected to the power component 20 is not limited. For example, it can be achieved by increasing the coefficient of friction of the contact surface between the lifting member 30 and the power component 20. For instance, the contact portion of one of the lifting member 30 and the power component 20 has a friction layer, which can dampen the movement of the lifting member 30. Alternatively, a friction element can be added between the lifting member 30 and the power component 20.

[0056] The first direction S and the second direction R refer to the direction of rotation. The first direction S can be either clockwise or counterclockwise. For example, referring to Figure 2, when the first direction S is clockwise, the second direction R is counterclockwise.

[0057] In this embodiment, one end of the cleaning component 12 is fixedly connected to the lifting component 30, the lifting component 30 is dampedly connected to the power component 20, the rotating shell 11 is spirally connected to the lifting component 30, and the power component 20 is drivenly connected to the rotating shell 11. When the power component 20 drives the rotating shell 11 to rotate, there is friction between the power component 20 and the lifting component 30, which causes the rotation of the lifting component 30 to stop or the rotation speed to be less than the rotation speed of the rotating shell 11. As a result, the lifting component 30 rises or falls along the rotation axis of the rotating shell 11 in a spiral or linear manner.

[0058] For example, the lifting component 30 descends to the first position, and the cleaning component 12 falls to contact the ground, performing cleaning operations along the first direction S under the drive of the power component 20. After the cleaning component 12 finishes its work, the driving direction of the power component 20 is changed, causing the rotating housing 11 to rotate in the opposite direction R. The lifting component 30 rises to the second position under the action of the damping connection, and the cleaning component 12 rises with the lifting component 30, thus lifting the cleaning component 12 off the ground. This reduces the risk of the cleaning component 12 soiling the cleaned ground due to contact with the ground, or wear and tear caused by contact with the ground when not in operation, thus minimizing the impact on the service life of the cleaning component 12.

[0059] The cleaning component 12 can be a side brush or a main brush. Its structure can be bristles for sweeping or a mop strip for mopping. The cleaning component 12 can be made of either a hard or soft material. Both hard and soft components can deform to some extent under external force, with hard components deforming less than soft components. For example, the cleaning component 12 can be made of a hard material, such as a hard plastic side brush, which has strong cleaning power, low deformation, and is suitable for cleaning hard floors. Alternatively, the cleaning component 12 can be made of a soft material, such as a soft plastic side brush, a soft rubber side brush, or a silicone side brush, which has low friction on the floor, is less likely to scratch the floor, and is suitable for carpets, high-grade wood, and other easily scratched floors.

[0060] The power assembly 20 provides the power for the cleaning assembly 10 to rotate for cleaning. Exemplarily, referring to Figures 2 and 3, the power assembly 20 includes a support portion 23 and a power unit 21. The power unit 21 is disposed on the support portion 23 and is drivenly connected to the cleaning assembly 10, for example, to the rotating housing 11, so that the cleaning assembly 10 can rotate relative to the support portion 23. The power unit 21 can be a motor, such as a brushed DC motor, a brushless DC motor, a stepper motor, or a servo motor. The support portion 23 provides a mounting base for related structures, such as for mounting transmission components and the cleaning assembly 10. The support portion 23 is detachably connected to the main body of the cleaning equipment.

[0061] For example, referring to Figure 3, the power assembly 20 also includes a transmission section 22, which is connected to both the power unit 21 and the rotating housing 11. That is, the power unit 21 is driven to the rotating housing via the transmission section 22. The support section 23 also includes a housing 231, in which the power unit 21 is disposed, and the transmission section 22 is disposed within the housing 231. The transmission section 22 can achieve transmission in any manner, such as gear transmission, worm gear transmission, belt transmission, chain transmission, etc. The speed ratio between the power unit 21 and the cleaning assembly 10 can be adjusted by providing the transmission section 22. For example, the transmission section 22 can be a deceleration transmission or a speed-increasing transmission.

[0062] For example, the transmission unit 22 includes a gear set for adjusting the speed difference between the cleaning component 10 and the power unit 21. Referring to FIG3, the transmission unit 22 includes a first transmission wheel 221, which has a connecting shaft 2211 protruding toward the rotating housing 11 for detachable connection with the cleaning component 10. When the cleaning component 10 malfunctions, such as being entangled in hair, the detachable connection between the cleaning component 10 and the transmission unit 22 facilitates hair removal compared to a direct connection between the cleaning component 10 and the power unit 21. For example, in cases where hair is difficult to remove, it is inconvenient to disassemble the power unit 21, but the transmission unit 22 can be disassembled, thereby reducing the possibility of the power unit 21 being entangled in hair and thus damaged.

[0063] Referring to Figure 3, the cleaning assembly 10 includes a fastener 40, and the power assembly 20 and the cleaning assembly 10 are connected by the fastener 40 for easy assembly and disassembly. For example, the rotating housing 11 has a second through hole 114a at its bottom. The rotating housing 11 includes a first convex ring 111 and an inner edge 114 disposed on the inner wall of the first convex ring 111, the inner edge 114 having the second through hole 114a. The fastener 40 connects the rotating housing 11 to the power assembly 20 along the second through hole 114a. For example, the fastener 40 passes through the second through hole 114a and is fixed to the connecting shaft 2211. For example, the connecting shaft 2211 has internal threads, the fastener 40 is a bolt, and the fastener 40 is threadedly connected to the connecting shaft 2211.

[0064] Referring to Figure 1, one end of the cleaning component 12 is located inside the rotating housing 11, and the other end protrudes outside the rotating housing 11. For example, referring to Figures 3-5, the rotating housing 11 has a first through hole 112a. One end of the cleaning component 12 passes through the first through hole 112a and can extend or retract within the first through hole 112a.

[0065] For example, referring to Figure 3, the rotating housing 11 further includes a second protruding ring 112 connected to the outer periphery of the first protruding ring 111. A guide groove 11a is formed between the first protruding ring 111 and the second protruding ring 112. The first protruding ring 111 is sleeved on the power assembly 20. The lifting member 30 is sleeved on the first protruding ring 111, and one end of the cleaning member 12 is disposed in the guide groove 11a and fixedly connected to the lifting member 30. For example, the lifting member 30 includes a cylinder 31, which is sleeved on the first protruding ring 111, and one end of the cleaning member 12 is disposed in the guide groove 11a and fixedly connected to the cylinder 31. In this way, the cleaning member 12 can pass through the first through hole 112a and move along the guide groove 11a to extend or retract.

[0066] For example, please refer to Figures 4-5. The second convex ring 112 includes an upper convex ring 1121 and a lower convex ring 1122 that are detachably connected. A first through hole 112a is provided on the upper convex ring 1121 and the lower convex ring 1122 to facilitate the disassembly and assembly of the cleaning component 12. The upper convex ring 1121 can shield the structure located inside the second convex ring 112, thus playing a protective and aesthetic role.

[0067] Please refer to Figures 3 and 6-9. One end of the cleaning component 12 is located inside the rotating housing 11 and is fixedly connected to the lifting component 30. That is, the cleaning component 12 can move with the lifting component 30. The cleaning component 12 and the lifting component 30 can be integrally molded or manufactured separately. For example, the cleaning component 12 and the lifting component 30 are integrally molded, and the cleaning component 12 is fixedly connected to the lifting component 30 by injection molding. Alternatively, the cleaning component 12 and the lifting component 30 are manufactured separately and can be detachably connected.

[0068] For example, the lifting component 30 also includes a flange 33 disposed on the outer wall of the cylinder 31, and one end of the cleaning component 12 is fixedly connected to the flange 33. The flange 33 can improve the fixing effect of the lifting component 30 and the cleaning component 12.

[0069] For example, flange 33 has a first fixing hole 33a, cylinder 31 has a first fixing post 311, and cleaning component 12 has a second fixing hole 12a and a second fixing post 121. The first fixing hole 33a is connected to the first fixing post 311, and the second fixing hole 12a is connected to the second fixing post 121. In this way, the fixing effect of lifting component 30 and cleaning component 12 can be further improved.

[0070] In some embodiments, the cleaning component 12 is a flexible component, and it is fixedly connected to the flange 33 and the cylinder 31 by injection molding. In this way, the cleaning component 12 is firmly connected to the lifting component 30 and is not easy to fall off.

[0071] In some embodiments, the cleaning component 12 is a flexible component, and the cleaning component 12 is detachably connected to the flange 33 and the cylinder 31. This facilitates the individual replacement of damaged cleaning components 12, or the replacement with cleaning components 12 of different specifications or materials.

[0072] In some embodiments, referring to Figure 3, one end of the lifting member 30 is dampedly connected to the power component 20. The cleaning module 100 also includes a friction element 13 disposed between the power component 20 and the lifting member 30, for example, between the support portion 23 and the lifting member 30, to dampen the movement of the lifting member 30. The lifting member 30 is dampedly connected to the power component 20 by installing the friction element 13, which facilitates adjustment of the coefficient of friction of the contact surface between the lifting member 30 and the power component 20, and facilitates maintenance and replacement when the friction element 13 is damaged. The friction element 13 can be sheet-shaped, strip-shaped, or ring-shaped.

[0073] For example, the lifting component 30 includes a cylindrical body 31, and the support portion 23 includes a first protrusion 232, which is disposed within the housing 231. The cylindrical body 31 is sleeved on the first protrusion 232, and the friction element 13 is located between the cylindrical body 31 and the first protrusion 232. The friction element 13 can be continuously arranged axially along the first protrusion 232, or multiple friction elements 13 can be arranged at intervals. The friction element 13 can also be continuously arranged circumferentially along the first protrusion 232, or multiple friction elements 13 can be arranged at intervals. For example, the friction element 13 is strip-shaped, and multiple strip-shaped friction elements 13 are arranged at intervals circumferentially along the first protrusion 232. Alternatively, the friction element 13 is annular and continuously arranged axially along the first protrusion 232.

[0074] Furthermore, referring to Figures 4-7, the other end of the lifting member 30 is helically connected to the rotating shell 11. Exemplarily, one of the rotating shell 11 and the lifting member 30 has a second protrusion 113, and the other has a helical groove 31a. The second protrusion 113 can move within the helical groove 31a, thereby achieving a helical connection between the lifting member 30 and the rotating shell 11. Exemplarily, the lifting member 30 includes a cylindrical body 31, the inner wall of which is provided with a helical groove 31a. The rotating shell 11 includes a first protruding ring 111 and a second protrusion 113 disposed on the outer wall of the first protruding ring 111. The second protrusion 113 can move within the helical groove 31a.

[0075] For example, the number of second protrusions 113 and spiral grooves 31a is the same, both being multiple, for example, three each. For example, the spiral grooves 31a gradually extend towards the ground along the first direction S.

[0076] For example, the spiral groove 31a includes an inlet end and an end end. The inlet end of the spiral groove 31a is located at the lower end of the cylinder 31 and extends through the lower end of the cylinder 31, for the second protrusion 113 to be inserted into the spiral groove 31a. The end end of the spiral groove 31a is located near the upper end of the cylinder 31, but does not extend through the upper end of the cylinder 31. Since the spiral groove 31a does not extend through the upper end, a stop portion 31b is formed at the end of the spiral groove 31a in the cylinder 31. When the lifting member 30 descends to the first position, the second protrusion 113 abuts against the stop portion 31b, so that the lifting member 30 rotates synchronously with the rotating shell 11, driving the cleaning member 12 to rotate for cleaning operations.

[0077] Based on the relevant structures of the above embodiments, the working process of the cleaning module 100 will be described exemplarily. The power unit 21 drives the rotating housing 11 to rotate via the transmission unit 22. When the rotating housing 11 rotates, it can cause the lifting member 30 to rise or fall relative to the support unit 23, thereby causing the cleaning component 12 to rise or fall. Specifically, when the rotating housing 11 rotates along the first direction S, it can cause the lifting member 30 to fall to a first position, so that the cleaning component 12 falls and contacts the ground. When the rotating housing 11 rotates along the second direction R, it can cause the lifting member 30 to rise to a second position, so that the cleaning component 12 rises and separates from the ground. The first direction S and the second direction R are opposite.

[0078] When the lifting component 30 is in the first position, the cleaning component 12 is at its lowest position relative to the support portion 23. When the lifting component 30 is in the second position, the cleaning component 12 is at its highest position relative to the support portion 23. When cleaning is required, the cleaning component 12 can descend to its lowest position to contact the ground for cleaning. After the cleaning operation is completed, the cleaning component 12 can rise to its highest position to separate from the ground, thereby reducing the possibility of the cleaning component 12 soiling the cleaned ground and potentially affecting its service life due to wear.

[0079] For example, when cleaning is required, the power unit 20 drives the rotating shell 11 to rotate in the first direction S, causing the lifting component 30 to rotate and descend simultaneously. Since one end of the lifting component 30 is dampedly connected to the power unit 20 and the other end is helically connected to the rotating shell 11, there is a speed difference between the rotating shell 11 and the lifting component 30. With the help of this speed difference, the rotating shell 11 can drive the lifting component 30 to descend, and the cleaning component 12 can follow the lifting mechanism 30 to descend and contact the ground. When the lifting component 30 descends to the first position, under the continued drive of the power unit 20, the rotating shell 11 and the lifting component 30 rotate synchronously, so that the cleaning component 12 can perform cleaning work.

[0080] When the cleaning operation is completed and the cleaning component 12 needs to be lifted, the power unit 20 drives the rotating shell 11 to rotate in the second direction R. The rotating shell 11 and the lifting component 30 have a speed difference, which causes the lifting component 30 to rotate and rise simultaneously. The cleaning component 12 rises with the lifting component 30, thus separating from the ground. When the lifting component 30 rises to the second position, the cleaning component 12 rises to its highest position, thus lifting the cleaning component 12.

[0081] The cleaning module 100 provided in this embodiment can simultaneously achieve the rotation and cleaning of the cleaning component 12 and the lifting and lowering of the cleaning component 12 by the power provided by the power component 20. After the cleaning operation is completed, the cleaning component 12 can be lifted off the ground, which can reduce the possibility of the cleaning component 12 soiling the cleaned ground or damaging the cleaning component 12. There is no need to set up a separate drive structure to drive the lifting and lowering of the cleaning component 12, which can reduce the production cost of the cleaning module 100.

[0082] To ensure the cleaning component 12 is fully lifted off the ground, reducing the risk of insufficient clearance due to gravity or other factors, in some embodiments (see Figure 3), the power assembly 20 is equipped with a first limiting member 24, and the lifting component 30 is equipped with a second limiting member 32. When the rotating housing 11 rotates along the second direction R, it can drive the lifting component 30 to rotate and rise to a third position. The second limiting member 32 abuts against the first limiting member 24 to restrict the rotation of the lifting component 30.

[0083] The third position is located between the first and second positions. That is, the axial height of the third position relative to the ground is less than that of the second position relative to the ground, and the axial height of the third position relative to the ground is greater than that of the first position relative to the ground.

[0084] Thus, by setting the first limiting member 24 and the second limiting member 32, when the lifting member 30 rotates and rises to the third position, the second limiting member 32 abuts against the first limiting member 24, restricting the rotation of the lifting member 30. At this time, if the rotating shell 11 continues to rotate, the lifting member 30 will rise linearly to the second position. During the linear rise of the lifting member 30, since the rotating shell 11 continues to rotate, and one end of the cleaning member 12 is fixed to the lifting member 30 and does not rotate with the rotating shell 11, a part of the cleaning member 12 will be dragged into the rotating shell 11, thus partially housed within the rotating shell 11, making the other end of the cleaning member 12 higher than the ground.

[0085] In other words, by setting the first limiting member 24 and the second limiting member 32, the lifting movement of the lifting member 30 is divided into two stages. Taking the lifting member 30 rising as an example, in the first stage, the lifting member 30 rotates and rises from the first position to the third position; in the second stage, the second limiting member 32 abuts against the first limiting member 24, and the lifting member 30 continues to rise linearly from the third position to the second position. In the first stage, the cleaning member 12 rises with the lifting member 30. In the second stage, while the cleaning member 12 continues to rise with the lifting member 30, a portion of it is pulled into the rotating shell 11, making the length of the cleaning member 12 suspended outside the rotating shell 11 shorter, thus raising the cleaning member 12 higher off the ground.

[0086] For example, the distance between the third position and the second position is 3 to 5 times the distance between the third position and the first position. For instance, the distance between the third position and the second position is L1, and the distance between the third position and the first position is L2. L1 can be 3L2, 3.5L2, 4L2, 4.5L2, or 5L2, etc. In this way, there is sufficient distance between the third position and the second position for the lifting member 30 to move upward, so that the cleaning component 12 is pulled further into the rotating housing 11, allowing the cleaning component 12 to fully lift off the ground.

[0087] When the cleaning component 12 is a soft component, it is pulled into the rotating housing 11. The portion of the cleaning component 12 fixed near one end of the lifting member 30 gradually deforms. As the rotating housing 11 continues to rotate, the deformation of the cleaning component 12 creates a stalling effect, thus stopping the rotation of the rotating housing 11. Alternatively, the lifting member 30 rises to abut against the power unit 20, for example, against the support part 23, thereby stopping the rotation of the rotating housing 11. Alternatively, the controller program can be set to stop the power unit 21 when the lifting height of the cleaning component 12 meets a preset requirement.

[0088] For example, when the lifting member 30 rotates and rises from the first position to the third position, the lifting member 30 moves upward along the axial direction by 0.5 mm. When the lifting member 30 is stopped by the limiting member and continues to rise linearly to the second position, the lifting member 30 continues to move upward along the axial direction by 2.0 mm.

[0089] It should be noted that when the second limiting member 32 abuts against the first limiting member 24, there is a certain distance between the top of the lifting member 30 and the support part 23. Thus, when the lifting member 30 reaches the third position, it can no longer rotate. Under the driving action of the power component 20, the rotating shell 11 continues to rotate to drive the lifting member 30 to move upward, and at the same time, it drives the cleaning member 12 to continue to move upward. The bottom end of the cleaning member 12 can move upward as a whole, further separating from the ground.

[0090] In some embodiments, please refer to Figures 8 and 9. The cleaning component 12 is a soft component, including a fixed section 122, a transition section 123 and a suspension section 124. The fixed section 122 is fixedly connected to the lifting component 30. At least a portion of the suspension section 124 is suspended outside the rotating shell 11. The transition section 123 connects the fixed section 122 and the suspension section 124. When the lifting component 30 descends to the first position, at least a portion of the transition section 123 is suspended outside the rotating shell 11. The height of the suspension section 124 is lower than that of the fixed section 122.

[0091] When the lifting member 30 descends to the first position, at least a portion of the transition section 123 is suspended outside the rotating housing 11; for example, the entire transition section 123 is suspended outside the rotating housing 11. Thus, the height of the suspended section 124 of the cleaning component 12 is designed to be lower than the fixed section 122, so that when the lifting member 30 descends to the first position, the end of the suspended section 124 of the cleaning component 12 can contact the ground for cleaning operations. When the cleaning operation is completed and the cleaning component 12 needs to be lifted, the power unit 20 switches the drive direction, and the lifting member 30 drives the cleaning component 12 to rise. As the rotating shell 11 continues to rotate, during the lifting process of the cleaning component 12, for example, the lifting component 30 rises from the first position to the second position, or from the third position to the second position, the transition section 123 is dragged into the rotating shell 11. The space inside the rotating shell 11, for example, the guide groove 11a, is limited, and the fixed section 122 and the transition section 123 will be squeezed and deformed. During the deformation process, the transition section 123 will twist, rotating the suspended section 124 upward by a certain angle, so that the suspended section 124 achieves an upward tilting effect, thereby greatly increasing the ground clearance of the cleaning component 12.

[0092] For example, the second fixing post 121 is disposed on the fixing section 122.
