[0003] In the field of mobile devices, to maximize the rigidity of the tires, the wheel rim and tire body are mostly designed as a single unit. When the tire body fails or is damaged, because the rim and tire body are difficult to separate, users have to replace both the rim and tire body together when replacing the tire. In addition, since most of the wheel structure is located inside the mobile device body, the replacement and assembly of the rim or tire body is extremely cumbersome and time-consuming, which not only affects the user experience but also increases the user's time and economic costs.

[0064] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0067] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0068] See Figure 1 , Figure 1 A schematic diagram of a mobile device according to an embodiment of this application is shown. The mobile device 1 provided in this embodiment includes wheels 10 and a body 20. The wheels 10 are connected to the body 20 and are rotatable relative to the body 20, thereby driving the body 20 to move on a work surface to complete the task. The mobile device 1 can be an intelligent robot, such as an intelligent sweeping robot, intelligent mopping robot, intelligent lawn mowing robot, intelligent snow removal robot, etc., which are mobile devices that complete specific tasks by moving.

[0069] In this application, a smart robotic vacuum cleaner is used as an example for description without limitation. The body 20 is provided with a battery pack mounting section (not shown) and working components, etc. The battery pack mounting section is used to mount a battery pack to power the device, and the working components are provided with working parts required for the operation of the mobile device 1. In the case of a smart robotic vacuum cleaner, the working part is a cleaning component 30.

[0070] In this application, as Figure 2 As shown, the mobile device 1 also includes a control system (not shown) for controlling the operation of the mobile device 1 and a drive member 40 for driving the working parts to perform the operation. The body 20 has a receiving cavity (not shown), and the drive member 40 and the control system are disposed in the receiving cavity. In the forward direction of the mobile device 1, the mobile device 1 has a front end and a rear end, and the cleaning member 30 is disposed at the front end, rear end, or middle of the mobile device 1. When in normal use, the mobile device 1 has a top surface (not shown) facing away from the ground, a bottom surface 21 facing the ground, and a peripheral side surface 22 connecting the bottom surface 21 and the top surface. The wheels 10 and the cleaning member 30 are both located on the bottom surface 21 of the body 20 so that the mobile device 1 can perform cleaning work when walking.

[0071] The cleaning component 30 includes at least one brush head. When the cleaning component has two brush heads, the brush heads are spaced apart to form a suction channel. During operation, the brush head is driven to rotate, thereby picking up debris from the ground. The debris then enters the body 20 through the suction channel. In other embodiments, the cleaning component 30 may also be a mop or a combination of a mop and a brush head, etc., which are not specifically limited here. The structure of the cleaning component 30 is prior art and will not be described in detail here.

[0072] The driving component 40 includes a cleaning prime mover and a walking prime mover 41. The cleaning prime mover is connected to the cleaning component 30 to drive the cleaning component 30 to rotate and perform cleaning work. The walking prime mover 41 drives the wheels 10 to rotate, which in turn propels the machine body 20 forward. In addition, the mobile device 1 also includes a sensor assembly, a fan system, a compression device, and a power supply device. The sensor assembly is used to realize the positioning, navigation, and sensing functions of the mobile device 1. The fan system is used to create suction force on the waste. Specifically, the fan system includes at least one fan. When the fan is started, it can create a negative pressure area within a certain range. The driving component 40 is connected to the power supply device, thereby driving the wheels 10 to rotate or the cleaning component 30 to work.

[0073] The number, distribution, and specific structure of the wheels 10 can be adapted to actual needs, and this application does not impose specific limitations here. For example, two wheels 10 can be provided, with two wheel sets symmetrically distributed on both sides of the center of the bottom surface 21 of the body 20. The mobile device 1 also includes omnidirectional wheels located at the front or rear end of the bottom surface 21 of the body 20, which are used for guidance, etc.

[0074] The following mainly describes the different structural forms of the wheel 10 and their different implementation methods.

[0075] In this application, firstly Figures 1 to 9The embodiment of the wheel structure shown will be explained in detail. Other embodiments will be described in detail as being different from the above embodiments. For similarities, please refer to the reference. This application will not repeat them here.

[0076] like Figure 3 , Figure 4 As shown, wheel 10 includes a tire body component 100 and a hub component 200. The hub component 200 is configured to rotate with an axle. The tire body component 100 includes a mounting member 120 and a tire skin 110 connected to the outer surface of the mounting member 120. The mounting member 120 is configured to support the tire skin 110 to prevent deformation of the tire skin 110. When the hub component 200 is mounted on the machine body 20, the tire body component 100 is detachably connected to the hub component 200, allowing the tire body component 100 to be mounted on or removed from the hub component 200, further facilitating the removal or installation of the tire skin 110 from the mounting member 120. In other words, when wheel 10 is mounted on the machine body 20, the above-mentioned removal and installation steps can be completed quickly, making it convenient to use and enabling rapid replacement of the tire skin 110.

[0077] In this embodiment, the mounting component 120 is detachably connected to the wheel hub component 200 via at least one fastening member. That is, the mounting component 120 can be detached from or connected to the wheel hub component 200. By setting the mounting component 120, the tire 110 can be installed on or removed from the wheel hub component 200, thus completing the quick replacement of the tire 110.

[0078] The tire body component 100 includes a mounting position connected to the hub component 200 and a separation position separated from the hub component 200. In the mounting position, such as... Figure 5 As shown, the tire carcass component 100 and the hub component 200 are mounted on the fuselage 20, and the tire carcass component 100 can rotate with the axle along with the hub component 200. In the separated position, as... Figure 6 As shown, the tire body component 100 can be separated from the fuselage 20, while the wheel hub component 200 remains connected to the fuselage 20 and can rotate with the wheel axle.

[0079] The tire carcass component 100 comprises at least two components, each of which is mounted after being mounted on the hub component 200. All tire carcass components 100 surround the hub component 200, forming a complete wheel 10 after mounting, and all tire carcass components 100 rotate synchronously with the hub component 200. Preferably, in… Figures 7 to 9In the illustrated embodiment, there are two tire body components 100. When the wheel 10 is mounted on the chassis 20, each of the two tire body components 100 undergoes two disassembly and removal actions. It can be understood that when there are more tire body components 100, each tire body component 100 can be independently and detachably connected to the wheel hub component 200. In this case, the number of tire body components 100 determines the number of removal actions during disassembly. When there are more tire body components 100, several of each tire body component 100 can be interconnected before being detachably connected to the wheel hub component 200, thereby reducing the number of removal actions during disassembly.

[0080] like Figure 5 , Figure 6 As shown, at least a portion of the wheel 10 protrudes from the bottom surface 21 of the body 20. When the wheel 10 rotates to a preset phase, at least a portion of the fastening member is exposed outside the body 20, facilitating disassembly and installation. When the wheel 10 contacts the ground, the portion of the wheel 10 protruding from the bottom surface 21 creates a gap between the ground and the bottom surface 21. When the wheel 10 is installed on the body 20, one of the tire body components 100 can be rotated to adjust its position. The fastening member follows the wheel 20 to rotate to a preset phase so that at least a portion protrudes from the bottom surface 21 and is exposed outside the body 20, facilitating the disassembly and removal of the tire body component 100. This allows one tire body component 100 to be in the separated position. The remaining tire body components 100 can then be disassembled and placed in the separated position by rotating the wheel 10, allowing the fastening members to be positioned protruding from the bottom surface 21 in sequence. This process is quick and convenient.

[0081] like Figure 2 and Figure 4 As shown, in this embodiment, the hub component 200 is provided with a transmission shaft 230 that transmits power toward the drive component 40, and the wheel 10 rotates synchronously with the transmission shaft 230.

[0082] The drive component 40 includes an output end for connection to the transmission wheel shaft 230, which is the output shaft of the prime mover 41. In this embodiment, the drive component 40 also includes a transmission assembly 42, which is disposed between the prime mover 41 and the wheel 10. The transmission assembly 42 transmits the power of the prime mover 41 to the wheel 10, thereby enabling the wheel 10 to rotate and complete the movement. The transmission assembly 42 can be a pulley set, a reduction gear set, etc., to achieve transmission functions such as speed regulation and deceleration. The output end is the output shaft of the transmission assembly 42.

[0083] The hub component 200 includes a transmission part 240 connected to a transmission shaft 230 and a support part 210 extending radially from the transmission part 240. The transmission shaft 230 and the transmission part 240 are arranged along a first direction, which is the axial direction of the wheel 10 and the hub component 200. When the mobile device 1 moves, the wheel 10 can rotate around the first direction, and in this application, the radial direction is perpendicular to the first direction. The support part 210 is circular and constitutes the main body of the hub component 200.

[0084] The tire skin 110 may include rubber, chemical additives, nylon fibers, and metal wires, etc. The tire skin 110 is provided with recessed patterns to increase friction. The shape and style of the recessed patterns are not limited, as long as they can achieve the purpose of increasing friction.

[0085] The elastic modulus of the mounting component 120 is greater than that of the tire skin 110, making it easier for the mounting component 120 to be detachably connected to the wheel hub component 200. The elastic modulus of the mounting component 120 is approximately equal to that of the wheel hub component 200, and their similar elastic moduli facilitate docking.

[0086] Specifically, the mounting component 120 is made of either a rigid or flexible material, while the wheel skin is made of a flexible material. It can be understood that a flexible material is defined as one capable of elastic deformation to a certain extent, while a rigid material is one without elasticity or whose elastic deformation does not meet the requirements. Preferably, the material of the mounting component 120 is the same as or has similar properties to the material of the wheel hub component 200 to facilitate docking.

[0087] The mounting component 120 is detached from the hub component 200 in a direction perpendicular to the central axis of the axle (drive axle 230 or drive unit 240). For ease of description, the direction parallel to the central axis of the drive axle 230 is defined as the first direction, i.e., the axial direction, and the detachment direction of the mounting component 120 is defined as the radial direction. The mounting component 120 is detachably connected to the support unit 210 and is detached from the hub component 200 in the radial direction, thereby allowing the tire liner 110 to be replaced without disassembling the machine, making the operation convenient.

[0088] It is understood that the hub component 200 and the tire body component 100 are coaxially arranged. The axial direction mentioned below refers to the first direction and the direction parallel to the first direction. The radial direction is all directions that are perpendicular to and intersect the first direction. The circumferential direction or circumferential side refers to the direction indicated by the arc formed around the first direction.

[0089] Please see Figure 9The mounting component 120 includes a mounting side 1201 and a mounting body 1202. The mounting body 1202 is generally semi-circular or fan-shaped, and correspondingly, the mounting side 1201 is arc-shaped. The mounting side 1201 is used to mount the tire cover 110. The mounting body 1202 can be detachably connected to the support portion 210 of the wheel hub component 200, and the mounting side 1201 is arranged around the periphery of the mounting body 1202. The tire cover 110 is detachably connected to the mounting side 1201 of the mounting component 120. The elastic modulus of the mounting body 1202 is greater than that of the tire cover 110. Specifically, the mounting body 1202 is made of rigid or flexible material. Preferably, the material of the mounting body 1202 is the same as or has similar properties to that of the wheel hub component 200.

[0090] Specifically, the tire skin 110 covers the mounting side 1201 and at least a portion of the side of the mounting body 1202. The tire skin 110 can be directly injection molded onto the mounting component 120. It is understood that in other embodiments, the mounting side 1201 can also be integrally molded with the tire skin 110, in which case the mounting body 1202 and the mounting side 1201 are composed of materials with different elastic moduli.

[0091] Please see Figure 8 and Figure 9 As described above, the mounting member 120 is detachably connected to the hub member 200 via at least one fastening member configured to restrict movement of the tire carcass member 100 relative to the hub member 200. When the fastening member is in the unlocked state, the tire carcass member 100 is detachable from the hub member 200; when the fastening member is in the locked state, the tire carcass member 100 is fixed to the hub member 200. Specifically, in one embodiment, the fastening member includes a connecting hole provided in the mounting member 120 and the hub member 200, and a fastener 300 that mates with the connecting hole. For ease of explanation, the connecting hole in the mounting member 120 is defined as a first connecting hole 212, and the connecting hole in the hub member 200 is defined as a second connecting hole 124. The fastener 300 and the connecting hole can be threaded together; the fastener 300 has external threads, and the connecting hole has internal threads that mate with the external threads. In other embodiments, the mounting member 120 and the hub member 200 can also be connected by a nut and the fastener 300 threaded together.

[0092] When the tire carcass component 100 is installed on the wheel hub component 200, after the second connecting hole 124 coincides with the first connecting hole 212, the fastener 300 passes through the second connecting hole 124 and the first connecting hole 212 to connect the wheel hub component 200 and the tire carcass component 100 to each other. Figure 5 , Figure 6As shown, by rotating the wheel 10, the portion with the fastener 300 can be positioned on the bottom surface 21, exposing the fastener 300. This allows the user to easily disassemble or install the tire body component 100 by releasing or installing the fastener 300, without needing to disassemble the entire wheel 10. In another embodiment, the fastening component includes a snap-fit ​​structure or locking structure that is respectively disposed on the mounting member 120 and the hub component 200 and engages with each other. The specific structure of the fastening component is not limited here.

[0093] Understandably, the fastener 300 can be located outside the body 20 only when the body component 100 needs to be disassembled or installed (switching between the installation position and the separation position). When the mobile device 1 is in normal operation, the fastener 300 may not be located outside the body 20.

[0094] To ensure the installation stability of the tire body component 100 and the wheel hub component 200, the number of fastening components is set to at least two, and two of the at least two first connecting holes 212 are arranged opposite to each other at both ends of the mounting component 120.

[0095] To reduce the number of fastening components, each tire carcass component 100 includes at least one mating portion 121, which protrudes radially relative to the mounting side 1201. This allows the mating portions 121 of adjacent tire carcass components 100 to overlap after being connected to the hub component 200, with the mounting parts 120 of adjacent tire carcass components 100 at least partially overlapping. A first connecting hole 212 is provided on the overlapping portion of the mating portion 121, and the center lines of the corresponding first connecting holes 212 coincide. Therefore, only one fastener 300 is needed to simultaneously connect adjacent ends of adjacent tire carcass components 100 to the hub component 200. This reduces the number of fastening components used, increases the mating stability of adjacent tire carcass components 100, and prevents gaps in the tire skin 110 between adjacent tire carcass components 100.

[0096] In this embodiment, at least two docking portions 121 are provided to ensure accurate docking alignment. Different docking portions 121 of the same tire body component 100 are staggered in the horizontal direction, and the staggering of the docking portion 121 of another tire body component 100 is symmetrical with the staggering of the adjacent tire body component 100, so that the docking portions 121 match each other after the adjacent tire body components 100 are docked.

[0097] Correspondingly, the first connecting hole 212 is provided in the support part 210. When the docking parts 121 of the adjacent tire body components 100 overlap, the adjacent second connecting holes 124 overlap with each other, and the second connecting hole 124 can overlap with the first connecting hole 212.

[0098] Specifically, when there are two tire body components 100, each tire body component 100 includes two mating parts 121, and only two fasteners 300 are needed to install all tire body components on the wheel hub component 200.

[0099] The disassembly process of the tire body component 100 in this embodiment includes the following steps: First, by rotating the wheel 10, each fastener 300 is exposed sequentially on the bottom surface 21 of the body 20. In particular, the position of the fastener 300 can be rotated to a higher point relative to the bottom surface 21, and the fastener 300 is removed from the hub component 200 and the mounting part 120. Second, the wheel 10 is rotated about 180 degrees, and another fastener 300 is removed from the hub component 200 in the same way as above. Then, the wheel 10 is rotated about 90 degrees, and the tire body component 100 is pulled out radially to the separation position, completing the disassembly process. The installation process of the tire carcass component 100 in this embodiment includes the following steps: First, the tire carcass component 100 is inserted radially from its separated position into the corresponding position of the wheel hub component 200, and the mounting component 120 is mated to the corresponding position of the wheel hub component 200; Second, by rotating the wheel 10, each second connecting hole 124 and its corresponding first connecting hole 212 are sequentially exposed on the bottom surface 21 of the body 20, and in particular, the positions of the second connecting hole 124 and its corresponding first connecting hole 212 can be rotated to a higher point relative to the bottom surface 21; Then, the fasteners 300 are sequentially inserted into the first connecting hole 212 and the second connecting hole 124 to connect the wheel hub component 200 and the mounting component 120, thus completing the installation process.

[0100] Furthermore, fastener 300 is a screw, such as... Figures 7 to 9 As shown, the screw includes a head 310 and a shank 320. During connection, the head 310 is located on the side of the hub component 200 facing outwards from the body 20. The shank 320 extends through the first connecting hole 212 and passes through the second connecting hole 124. A nut is provided at the end of the shank 320, and the nut is threadedly connected to the shank 320 to lock the mounting component 120 to the support portion 210. Specifically, the support portion 210 has a fastening groove 211 on the side facing away from the drive shaft 230 to accommodate the head 310 of the fastener 300. The bottom of the fastening groove 211 has a first connecting hole 212 through which the shank 320 passes. Both the fastening groove 211 and the fastener 300 are exposed on the body 20, facilitating the user's disassembly or installation of the tire body component 100.

[0101] The aforementioned fastening components at least restrict the radial and axial movement of the tire body component 100 relative to the wheel hub component 200. (See also...) Figures 7 to 9The mounting component 120 has a limiting part 122, and the hub component 200 has a connecting part 213. After the mounting component 120 is connected to the hub component 200, the limiting part 122 is connected to the connecting part 213 to at least restrict the circumferential movement of the mounting component 120 relative to the hub component 200. The limiting part 122 is located in the middle of the mounting body 1202, and the limiting part 122 is spaced apart from the mating part 121. The connecting part 213 is a frame-shaped structure protruding from the support part 210 or a groove-shaped structure recessed in the limiting part 122. After the mounting component 120 is connected to the hub component 200, the limiting part 122 is inserted into the groove-shaped or frame-shaped connecting part 213. Limiting grooves 125 are formed on both sides of the limiting part 122, and the limiting grooves 125 are engaged with the outer wall of the connecting part 213 to achieve a stable connection.

[0102] The mounting component 120 is also provided with a positioning part 123 and a limiting hole 126. The positioning part 123 and the limiting part 122 are spaced apart and separated by the limiting hole 126. The limiting hole 126 is a through hole and has the same shape as the connecting part 213 so as to avoid the connecting part 213 after the mounting component 120 is connected to the hub component 200. The connecting part 213 has an opening 2131 for the limiting part 122 to enter and an end 2132 away from the opening 2131. When the tire carcass component 100 is installed, the limiting part 122 enters from the opening 2131 and terminates in the connecting part 213 by the limiting groove 125 or the end 2132. After the tire carcass component 100 is connected and installed, the positioning part 123 abuts against and matches the end 213 by passing through the limiting hole 126 across the connecting part 213. The positioning part 123 can assist the connection between the limiting part 122 and the connecting part 213.

[0103] Furthermore, the positioning part 123 connects to adjacent mating parts 121 of the same tire carcass component 100. The adjacent mating parts 121 of the same tire carcass component 100 protrude from the mounting side at different distances, and the positioning part 123 connects the adjacent mating parts 121, serving a reinforcing and supporting function. After adjacent tire carcass components 100 are connected to the hub component 200, the adjacent mating parts 121 overlap, and the adjacent positioning parts 123 are spaced apart, with the drive wheel axle 230 passing between the adjacent positioning parts 123.

[0104] In other embodiments, the mounting component 120 may be a part of the hub component 200, referred to as a hub split. The hub component includes a hub body (i.e., the hub component 200 in the above embodiment) and a hub split (i.e., the mounting component 120 in the above embodiment), and a tire cover is provided on the hub split. It is understood that the division of the above mounting component does not affect the specific structure.

[0105] In other embodiments, such as Figure 10As shown, the mating portion 521 of the wheel 50 may not protrude from the mounting side. The limiting portion includes a first limiting portion 522, a second limiting portion 523 located at the edge of the mounting body 5201, and a third limiting portion 524 provided on the first limiting portion 522. Multiple mating portions 521 are provided, respectively located between the first limiting portion 522, the second limiting portion 523, or the third limiting portion 524. Correspondingly, the connecting portion includes a first connecting portion 512, a second connecting portion 513, and a third connecting portion 514. The first connecting portion 512 can connect to the first limiting portion 522, the second connecting portion 513 can connect to the second limiting portion 523, and the third connecting portion 514 can connect to the third limiting portion 524.

[0106] The first limiting part 522 has limiting grooves 522 on both sides. After the mounting part 120 is connected to the wheel hub component 200, the first limiting part 522 is inserted into the groove-shaped or frame-shaped first connecting part 512, and the limiting groove 522 is engaged with the outer wall of the second connecting part 513. The first connecting part 512 has an opening for the first limiting part 522 to enter and an end away from the opening. When the tire body component 100 is connected and installed, the first limiting part 522 enters from the opening and terminates in the first connecting part 512 by the limitation of the limiting groove 522. The third limiting part 524 is located at the end of the first limiting part 522. After the tire carcass components are connected and installed, the third limiting part 524 extends from its end and connects with the third connecting part 514 located in the support part 210. Specifically, the third connecting part 514 includes a limiting clip and a locking slot. The third limiting part 524 consists of two opposing elastic members. After being compressed, the elastic members enter the locking slot. Due to the elastic force of the reset, the third limiting part 524 abuts against the limiting clip. The second limiting parts 523 of adjacent tire carcass components 100 are oppositely arranged and are connected to the second connecting part 513. The second limiting part 523 is groove-shaped. The second limiting parts 523 of adjacent tire carcass components 100 together form a complete groove, and the shape of the second connecting part 513 is consistent with the shape of the complete groove.

[0107] See Figures 11 to 14Furthermore, the wheel 10 also includes a blocking member 220 for connecting to and rotating synchronously with the transmission unit 240. The blocking member 220 is closer to the output end than the support unit 210. In this embodiment, the blocking member 220 and the support unit 210 are integrally formed. In the first direction, the blocking member 220 and the support unit 210 are spaced apart, and a receiving cavity 101 for accommodating foreign objects sucked into the wheel is formed between the blocking member 220 and the support unit 210. The foreign objects mainly include hair, garbage, etc. The transmission unit 240 can be integrally formed with the blocking member 220. It should be noted that the blocking member 220 in this embodiment can be used alone on the wheel, or it can be used in combination with other structures on the wheel (operating channel, tire body component detachably connected to the wheel hub component) in the above or below embodiments. For example, the blocking member 220 can be used in the wheel together with the tire carcass member that is detachably connected to the hub member, or the blocking member can exist alone in the wheel without a tire carcass member that is detachably connected to the hub member (i.e. the tire carcass member is not detachable from the hub member).

[0108] In other embodiments, see again Figure 10 The transmission part 530 is sleeved on the transmission wheel shaft, and the blocking part 540 is sleeved on the outside of the transmission part 530 and fixedly connected to the support part 210 at intervals by bolts.

[0109] Since the wheel 10 needs to rotate, there is a clearance 424 between the wheel 10 and the transmission assembly 42. During the cleaning process, after the hair enters the wheel 10 through the clearance 424, it will stay in the receiving cavity 101 due to the setting of the blocking member 220, preventing the hair from getting tangled on the end of the transmission shaft 230 connected to the drive member 40. This avoids the problem of the hair squeezing the wheel 10 outward after getting tangled, causing the transmission shaft 230 to lose its connection with the prime mover 41.

[0110] Specifically, such as Figure 12 As shown, the mounting part 120 of the tire body component 100 and the support part 210 of the hub component 200 constitute a first sidewall surrounding the receiving cavity 101, the blocking part 220 of the hub component 200 and a part of the transmission assembly 42 constitute a second sidewall surrounding the receiving cavity 101, the first sidewall and the second sidewall are arranged opposite to each other, the mounting side and the tire skin 110 constitute a peripheral sidewall surrounding the receiving cavity 101, and the peripheral sidewall is located between the first sidewall and the second sidewall.

[0111] In the radial direction, the gap between the outer peripheral edge of the blocking member 220 and the inner periphery of the tire carcass member 100 or the hub member 200 is 1mm-2mm, which prevents hair from escaping from the receiving cavity 101 while ensuring that the blocking member 220 does not obstruct the transmission assembly 42. Preferably, the gap between the outer edge of the blocking member 220 and the tire carcass member 100 or the hub member 200 can be 1.3mm, 1.5mm, or 1.8mm.

[0112] The outer diameter of the blocking member 220 is smaller than the inner diameter of the tire body member 100 or the hub member 200. The transmission assembly 42 includes a transmission unit (not shown) and a housing surrounding the transmission unit. The housing includes a receiving shell 421 for accommodating the transmission unit. The receiving shell 421 has a through hole through which the transmission shaft 230 can pass and connect to the internal transmission unit.

[0113] In this embodiment, a flange 423 is provided on the outer periphery of the housing 421 extending axially. The outer diameter of the flange 423 is smaller than the inner diameter of the tire body component 100 or the hub component 200, and the inner diameter of the flange 423 is larger than the outer diameter of the blocking member 220. In the axial direction, the tire body component 100 and the flange 423 at least partially overlap.

[0114] Specifically, the flange 423 is surrounded inside the carcass member 100, and at least a portion of the blocking member 220 is surrounded inside the flange 423. In the axial direction, the flange 423 is flush with the outer side of the receiving cavity 101 and one side of the carcass member 100. A gap exists between the flange 423 and the carcass member 100, namely the aforementioned clearance gap 424. The flange 423 extends axially toward the receiving cavity 101 to surround at least a portion of the blocking member 220. A gap exists both axially and radially between the outer edge of the blocking member 220 away from the receiving cavity 101 and the inner side of the flange 423 toward the receiving cavity 101. The diameter of the blocking member 220 is greater than or equal to 14 mm. In the radial direction, the gap between the outer edge of the blocking member 220 and the inner surface of the flange 423 is 1mm-2mm. Preferably, the gap is 1.3mm, 1.5mm, or 1.8mm. In the axial direction, the gap between the outer edge of the blocking member 220 and the inner surface of the flange 423 can be less than or equal to 2mm. Preferably, the gap is less than or equal to 1mm. In other words, the difference between the inner radius of the flange 423 and the outer radius of the blocking member 220 is 1mm-2mm. Preferably, the difference is 1.3mm, 1.5mm, or 1.8mm.

[0115] In the axial direction, the carcass member 100 and the flange 423 at least partially overlap. Specifically, at at least one position in the axial direction, the carcass member 100 and the flange 423 are located in the same plane. Furthermore, the flange 423 extends in the axial direction toward the receiving cavity 101 beyond the position where the blocking member 220 is located away from the outermost part of the receiving cavity 101, so that the length of the clearance gap 424 extends beyond the position of the aforementioned gap (between the blocking member 220 and the flange 423) to form a labyrinth structure, allowing hair to be guided into the receiving cavity 101.

[0116] In other embodiments, the receiving shell 421 does not have an axially extending flange 423, but only a radially extending blocking shell 422. The blocking shell 422 is surrounded inside the tire carcass member 100, and the blocking member 220 is spaced apart from the blocking shell 422. In the axial direction, the outer side of the blocking shell 422 facing away from the receiving cavity 101 is flush with one side of the tire carcass member 100. There is a gap between the outer periphery of the blocking shell 422 and the tire carcass member 100, namely the aforementioned clearance gap 424. The blocking shell 422 has a certain thickness, and in the axial direction, along the thickness direction, the blocking shell 422 extends toward the receiving cavity 101 to form a clearance gap 424 between its outer edge and the wheel 10. There is an axial gap between the outer edge of the blocking member 220 facing away from the receiving cavity 101 and the blocking shell 422. The diameter of the blocking member 220 is greater than or equal to 14 mm. In the axial direction, the gap between the outer edge of the blocking member 220 and the inner diameter of the mounting side 1201, the inner diameter of the hub member 200, or the inner surface of the blocking shell 422 is 1mm-2mm to prevent hair from entering. Preferably, the gap between the outer edge of the blocking member 220 and the inner surface of the blocking shell 422 is 1.3mm, 1.5mm, or 1.8mm. In other words, the difference between the radius of the blocking shell 422 and the outer radius of the blocking member 220 is 1mm-2mm. Preferably, the difference between the radius of the blocking shell 422 and the outer radius of the blocking member 220 is 1.3mm, 1.5mm, or 1.8mm. In the axial direction, since the blocking shell 422 has a certain thickness, the tire carcass member 100 and the blocking shell 422 at least partially overlap. Specifically, at least at one position in the axial direction, the tire carcass member 100 and the blocking shell 422 are located in the same plane.

[0117] It is understandable that, such as Figure 15 , Figure 16 As shown, the blocking member 220 is applicable to wheels 10 in which one or more tire body components 100 are detachably connected to the wheel hub component 200 via the mounting member 120 in the above embodiments, and the blocking member 220 is also applicable to conventional wheel 10 structures.

[0118] Please see Figure 12The tire body component 100 is disposed on the outer peripheral surface of the hub component 200. The hub component 200 and the tire body component 100 together form a receiving cavity 101. The tire body component 100 and / or the hub component 200 are provided with at least one radially penetrating operating channel that communicates with the receiving cavity 101. The operating channel allows the receiving cavity 101 to communicate with the external space, and the user can remove hair, foreign objects, etc. contained therein through the operating channel. It should be noted that the operating channel in this embodiment can be used alone on the wheel, or it can be used in combination with other structures on the wheel in the above embodiments. For example, the operating channel can be used in the wheel together with the above-mentioned blocking member and / or the tire body component detachably connected to the hub component, or the operating channel can exist alone in the wheel without the blocking member and / or the tire body component detachably connected to the hub component.

[0119] In the embodiments described above where the tire carcass components 100 are detachably connected, the operating channel can be formed on the tire carcass component 100 or between adjacent tire carcass components 100. For example, in some embodiments, when at least one tire carcass component 100 is detached, the receiving cavity 101 is directly exposed to the external space, and the receiving cavity 101 serves as the operating channel. As another example, in some embodiments, the mounting member 120 and the tire skin 110 are provided with operating grooves that connect the receiving cavity 101 to the external space. The operating grooves of adjacent tire carcass components 100 are matched. After adjacent tire carcass components 100 are installed onto the hub component 200, the adjacent operating grooves abut each other to form an operating channel. The operating groove can also be considered as a notch reserved when adjacent tire carcass components 100 abut.

[0120] In other embodiments, such as Figure 17 As shown, for a conventional wheel 60, the wheel 60 includes a complete tire component (not shown) and a complete hub component 600. The hub component 600 has an operating port 610 communicating with the receiving cavity. The tire component may have an opening that matches the operating port 610, or it may not have an opening. If the tire component does not have an opening, and the tire component is solid (including having an inner tube), the hair will not be thrown out of the opening after the tire component is installed. After the tire component is removed from the hub component 200, the operating port 610 becomes the operating channel through which the hair can be removed. Furthermore, if the tire component is a hollow structure, the operating port 610 may also have an operating cover that can be selectively opened. After the tire component is removed from the hub component 200, opening the operating cover opens the operating port 610, which becomes the operating channel through which the hair can be removed.

[0121] Furthermore, the operating port 610 is located at the center of the radial direction on the circumferential side of the hub component 600 to ensure the strength of the hub component 600. The support part of the hub component 600 may also be provided with a notch that matches the position of the operating port 610. The notch and the operating port 610 together form part of the operating channel, making it easier to remove hair smoothly.
