[0073] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0074] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0075] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0076] When expressions such as "at least one of A, B and C, etc." are used, they should generally be interpreted in accordance with the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0077] The present disclosure provides a shock-absorbing hub, a wheel, and a mobile device. The shock-absorbing hub specifically comprises: an outer hub; an inner hub mounted at the center of a circle defined by the outer hub; and a plurality of support devices connected between the inner hub and the outer hub, each support device elastically contracting under the compression of the inner hub and the outer hub.

[0078] Figure 1 A schematic plan view of a wheel according to an embodiment of the present disclosure is shown schematically.

[0079] like Figure 1 As shown, the shock absorbing hub may include an outer hub 100, an inner hub 200, a plurality of supporting devices 300, and a tire mounted on the outer hub.

[0080] Furthermore, the inner hub 200 is installed at the center of the circle defined by the outer hub 100; multiple support devices 300 are connected between the inner hub 200 and the outer hub 100, and each support device 300 is elastically contracted by the squeezing of the inner hub 200 and the outer hub 100.

[0081] According to an embodiment of the present disclosure, the inner hub 200 is provided with a drive shaft connected to the mobile device. When the shock-absorbing hub is connected to the mobile device, the mobile device will vibrate when the mobile device travels on uneven roads. At this time, the outer hub 100 and the inner hub 200 are squeezed, causing the support device 300 located between the inner hub 200 and the outer hub 100 to elastically contract. This allows the support device 300 to absorb the energy generated by the vibration through elastic deformation, preventing damage to components within the mobile device caused by the vibration and indirectly extending the service life of the wheeled robot.

[0082] According to an embodiment of the present disclosure, the outer hub 100 and the inner hub 200 are connected by the support device 300. When the mobile device is subjected to vibration, the support device 300 is elastically contracted by the squeezing of the inner hub 200 and the outer hub 100, and can absorb the energy generated by the vibration, thereby avoiding damage to the components inside the mobile device and improving the stability of the mobile device.

[0083] Figure 2 A schematic diagram of a wheel according to another embodiment of the present disclosure is schematically shown.

[0084] In an exemplary embodiment, Figure 2 As shown, each supporting device 300 may include a spring plate 311 , wherein a first end and a second end of the spring plate 311 are connected to the inner hub 200 and the outer hub 100 respectively.

[0085] According to an embodiment of the present disclosure, the spring plate 311 may be made of spring steel material to provide sufficient supporting strength and elasticity.

[0086] According to an embodiment of the present disclosure, when the mobile device moves, extrusion occurs between the outer hub 100 and the inner hub 200. At this time, the elastic plate located between the inner hub 200 and the outer hub 100 undergoes elastic deformation, thereby absorbing the energy generated by the vibration, thereby avoiding damage to the components inside the mobile device caused by the vibration.

[0087] According to an embodiment of the present disclosure, the spring plate 311 is arranged so that a straight line connecting the two ends of the spring plate 311 forms a preset angle with a radial line passing through the midpoint of the straight line. In other words, the straight line connecting the two ends of the spring plate 311 does not extend in the radial direction of the hub.

[0088] According to an embodiment of the present disclosure, the preset angle can be specifically set according to actual needs, for example, it can be 10 degrees, 15 degrees, 20 degrees, 30 degrees, etc.

[0089] According to an embodiment of the present disclosure, the spring plate 311 is arranged at a preset angle to the radial radiation line passing through the midpoint of the straight line, so that the shock-absorbing hub can undergo elastic deformation in time when it is impacted, thereby better absorbing the energy generated by the vibration.

[0090] like Figure 2 As shown, the shock absorbing hub may further include a flange 312 protruding radially inward from the inner side of the outer hub 100 , and the second end of the spring plate 311 is connected to the flange 312 .

[0091] According to an embodiment of the present disclosure, the number of the flange 312 may be one or more.

[0092] According to an embodiment of the present disclosure, in order to strengthen the connection strength between the spring plate 311 and the outer hub 100 and avoid breakage at the connection between the spring plate 311 and the outer hub 100 when the shock-absorbing hub is in use, a flange 312 can be provided at the outer hub 100 connected to the spring plate 311, thereby strengthening the connection strength between the spring plate 311 and the outer hub 100 and extending the service life of the shock-absorbing hub.

[0093] According to an embodiment of the present disclosure, a plurality of spring plates 311 may be located on both sides of the flange 312 , wherein the spring plates 311 on both sides may be arranged to cross at an angle.

[0094] Figure 3 A perspective view of a spring plate according to an embodiment of the present disclosure is schematically shown.

[0095] like Figure 2 and Figure 3 As shown, a plurality of first limiting grooves 313 are provided on the inner hub 200; a plurality of connecting blocks are provided on the flange 312, each connecting block is provided with a second limiting groove 314, and the first end and the second end of each spring plate 311 are respectively combined with the first limiting groove 313 and the second limiting groove 314.

[0096] According to an embodiment of the present disclosure, both ends of the spring plate 311 are movable relative to the first limiting groove 313 and the second limiting groove 314 , thereby facilitating replacement of a damaged or poorly performing spring plate 311 during maintenance.

[0097] like Figure 3As shown, the first end and the second end of the spring plate 311 are respectively curled into annular portions 315 , and the two annular portions 315 are elastically inserted into the first limiting groove 313 and the second limiting groove 314 .

[0098] According to an embodiment of the present disclosure, in order to prevent the spring plate 311 from falling off from the first limiting groove 313 and the second limiting groove 314, the two ends of the spring plate 311 can be set to an annular portion 315 that matches the shape of the first limiting groove 313 or the second limiting groove 314, so that the connection between the spring plate 311 and the first limiting groove 313 or the second limiting groove 314 is tighter, thereby improving the connection strength and avoiding the problem of the spring plate 311 falling off during use of the shock-absorbing hub.

[0099] like Figure 3 As shown, the first limiting groove 313 and the second limiting groove 314 are respectively provided with radially open openings, so that the two ends of the spring plate 311 pass through the openings and engage with the first limiting groove 313 and the second limiting groove 314. In this way, the two ends of the spring plate 311 can be installed in the first limiting groove 313 and the second limiting groove 314 in the axial direction, and a portion of the spring plate passes through the openings.

[0100] According to an embodiment of the present disclosure, the provision of the opening facilitates the installation and removal of the spring plate 311. For example, during the installation of the spring plate 311, the spring plate 311 can be inserted into the first limiting groove 313 or the second limiting groove 314 through the opening on the first limiting groove 313 or the second limiting groove 314.

[0101] like Figure 3 As shown, a wear-resistant ring 316 may be sleeved on the outside of each annular portion 315 .

[0102] According to an embodiment of the present disclosure, in order to reduce the wear of the spring plate 311 during the use of the shock-absorbing hub, wear-resistant rings 316 can be provided on the annular portions 315 at both ends of the spring plate 311 to extend the service life of the spring plate 311 and reduce the cost of the shock-absorbing hub.

[0103] like Figure 3 As shown, the spring plate 311 has a generally arc-shaped outer contour.

[0104] According to an embodiment of the present disclosure, in order to enable the spring plate 311 to better elastically deform under the pressure of the inner hub 200 and the outer hub 100, an arc-shaped spring plate 311 can be used. This allows the spring plate 311 to deform along the arc under pressure. This prevents the spring plate 311 from bending and deforming, and improves its elasticity.

[0105] Figure 4A three-dimensional schematic diagram of a wheel according to an embodiment of the present disclosure is schematically shown, in which the position of the first baffle is shown.

[0106] In one embodiment, if Figure 4 As shown, each of the first limiting groove 313 and the second limiting groove 314 is provided with a first blocking piece 317 , and each first blocking piece 317 is configured to limit the annular portion 315 from being separated from the first limiting groove 313 or the second limiting groove 314 .

[0107] According to an embodiment of the present disclosure, in order to prevent the spring plate 311 from detaching from the first limiting groove 313 or the second limiting groove 314 during use of the shock-absorbing hub, a first blocking piece 317 can be provided on the outer side of the first limiting groove 313 and the second limiting groove 314.

[0108] According to an embodiment of the present disclosure, the connection relationship between the first blocking piece 317 and the first limiting groove 313 or the second limiting groove 314 can be, but is not limited to, bolt connection, welding, or other connection methods.

[0109] Figure 5 A perspective view of a wheel according to another embodiment of the present disclosure is schematically shown.

[0110] In an exemplary embodiment, Figure 5 As shown, each supporting device 300 may include a hollow shock-absorbing cylinder 321 , an elastic component 322 and two connecting components 323 .

[0111] The elastic component 322 is disposed within the shock-absorbing cylinder 321. Two connecting components 323 are disposed at either end of the shock-absorbing cylinder 321 and are connected to the inner hub 200 and the outer hub 100, respectively. At least one of the two connecting components 323 is elastically contracted relative to the shock-absorbing cylinder 321 by being squeezed by the inner hub 200 and the outer hub 100.

[0112] According to an embodiment of the present disclosure, when the mobile device moves, extrusion occurs between the outer hub 100 and the inner hub 200. At this time, a connecting component 323 located between the inner hub 200 and the outer hub 100 undergoes elastic deformation in the radial direction, thereby absorbing the energy generated by the vibration, thereby avoiding damage to the components inside the mobile device caused by the vibration.

[0113] Figure 6 Schematically shows Figure 5 Partial radial section through the wheel shown.

[0114] In one embodiment, if Figure 6As shown, the elastic assembly 322 may include a support plate 3221, two springs 3222, and a shock-absorbing rod 3223. The support plate 3221 is movably disposed within the shock-absorbing cylinder 321. The two springs 3222 are disposed on either side of the support plate 3221 within the shock-absorbing cylinder 321. The shock-absorbing rod 3223 extends from the support plate 3221 to the first end of the shock-absorbing cylinder 321 and is connected to the inner hub 200.

[0115] According to an embodiment of the present disclosure, the spring 3222 may include a coil spring, a volute spring, a leaf spring, a disc spring, an annular spring, a special-shaped spring, etc.

[0116] According to an embodiment of the present disclosure, when extrusion occurs between the outer hub 100 and the inner hub 200, the force generated by the extrusion acts on the support plate 3221 through the shock-absorbing rod 3223. The support plate 3221 undergoes elastic deformation under the action of the two springs 3222, thereby absorbing the energy generated by the vibration, thereby avoiding damage to the components inside the mobile device due to the vibration and extending the service life of the mobile device.

[0117] like Figure 6 As shown, a plurality of third limiting grooves 324 are evenly distributed on the outer circumference of the inner hub 200, and a plurality of fourth limiting grooves 325 are provided on the inner side of the outer hub 100, which are radially opposite to the plurality of third limiting grooves 324 respectively.

[0118] According to an embodiment of the present disclosure, both ends of the support device 300 are movable relative to the third limiting groove 324 and the fourth limiting groove 325 , thereby facilitating replacement of a damaged support device 300 during maintenance.

[0119] According to an embodiment of the present disclosure, each of the third limiting groove 324 and the fourth limiting groove 325 is provided with a second blocking piece, and each second blocking piece is configured to limit the support device 300 from detaching from the third limiting groove 324 or the fourth limiting groove 325 .

[0120] According to an embodiment of the present disclosure, in order to prevent the support device 300 from disengaging from the third limiting groove 324 or the fourth limiting groove 325 during use of the shock-absorbing hub, a second blocking piece can be provided on the outer side of the third limiting groove 324 and the fourth limiting groove 325.

[0121] According to an embodiment of the present disclosure, the connection relationship between the second blocking piece and the third limiting groove 324 or the fourth limiting groove 325 can be, but is not limited to, bolt connection, welding, or other connection methods.

[0122] Figure 7 A cross-sectional view of a supporting device according to an embodiment of the present disclosure is schematically shown.

[0123] In one embodiment, if Figure 7 As shown, the support device 300 may further include a first joint 326 and a second joint 327. The first joint 326 is provided on one connecting component 323 and engages with the fourth limiting groove 325. The second joint 327 is provided on the other connecting component 323 and connects with the third limiting groove 324.

[0124] According to an embodiment of the present disclosure, the shapes of the first joint 326 and the second joint 327 may include but are not limited to a spherical shape or a cylindrical shape.

[0125] According to an embodiment of the present disclosure, a wear-resistant layer may also be provided at the ends of the first joint 326 and the second joint 327, or a wear-resistant layer may be provided in the third limiting groove 324 and the fourth limiting groove 325, so as to prevent the shock-absorbing hub from being unusable due to wear of the first joint 326 and the second joint 327 during use.

[0126] In one embodiment, if Figure 7 As shown, the shock absorber 321 may include a cylinder 3211 with two open ends, a first end cap 3212, and a second end cap 3213. The first end cap 3212 is mounted on one end of the cylinder 3211 and is connected to the outer hub 100 via a connecting assembly 323. The second end cap 3213 is mounted on the other end of the cylinder 3211. The elastic assembly 322 passes through the second end cap 3213 and is connected to the inner hub 200 via another connecting assembly 323.

[0127] According to an embodiment of the present disclosure, in order to facilitate the manufacture of the shock-absorbing hub, the support plate 3221, the spring 3222 and the shock-absorbing rod 3223 can be installed using a hollow cylinder 3211, and the first end cover 3212 and the second end cover 3213 can be used to seal the two ends of the cylinder 3211.

[0128] According to an embodiment of the present disclosure, the first end cover 3212 and the second end cover 3213 may be connected to the cylinder 3211 by threaded connection or welding.

[0129] Another aspect of the present disclosure provides a wheel, which may include the shock-absorbing hub as described above, and a tire mounted on the shock-absorbing hub.

[0130] According to an embodiment of the present disclosure, the outer hub 100 and the inner hub 200 are connected by the support device 300. When the wheel is subjected to vibration, the support device 300 is squeezed by the inner hub 200 and the outer hub 100 and elastically contracts, and can absorb the energy generated by the vibration, thereby avoiding the problem of damage to the components of the mobile device caused by the vibration of the outer hub 100.

[0131] Another aspect of the present disclosure provides a mobile device, which may include the plurality of wheels described above.

[0132] According to an embodiment of the present disclosure, the mobile device may include but is not limited to a robot.

[0133] According to an embodiment of the present disclosure, when the mobile device is moving on an uneven road, the tire will be displaced in the vertical direction with the undulations of the road surface. At this time, the outer hub 100 will be displaced synchronously to squeeze the inner hub 200. Since the support device 300 can elastically contract with the squeezing of the inner hub 200 and the outer hub 100, it can absorb the energy of the vibration, thereby avoiding the problem of damage to the internal components of the mobile device caused by the vibration of the outer hub 100.
