[0046] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art.

[0047] To make the technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the drawings.

[0048] Figure 1 It is a schematic three - dimensional structure diagram of a wheel hub in the related art. Figure 2It is a schematic cross-sectional structure diagram of a wheel hub in the related art. Please refer to Figure 2 , since the wheel hub 100 in the wheel is an integral structure, and the rim in the wheel hub 100 is recessed toward the axis line of the wheel hub 100, in the radial direction of the wheel hub 100, the space on the wheel hub 100 where the motor can be installed is compressed. This product structure limits the size and power of the motor that can be matched, reducing the performance of the whole vehicle.

[0049] To solve the problem of limited installation space for the motor on the wheel hub 100, the present application provides a wheel hub, a wheel and an automobile. The specific technical solutions are introduced as follows:

[0050] Figure 3 It is a schematic structure diagram of a wheel hub provided by an embodiment of the present application. Please refer to Figure 3 , an embodiment of the present application provides a wheel hub 000, including: an outer rim portion 010, a rim ring 020, and an inner rim portion 030.

[0051] Along the axial direction of the wheel hub 000, the rim ring 020 is located between the outer rim portion 010 and the inner rim portion 030, and one side of the rim ring 020 is connected to the side of the outer rim portion 010 facing the rim ring 020, and the other side of the rim ring 020 is connected to the side of the inner rim portion 030 facing the rim ring 020.

[0052] Wherein, a first groove C1 is formed by enclosing between the rim ring 020 and the inner rim portion 030. The notch of the first groove C1 is located on the side facing the axis line of the wheel hub 000, and the first groove C1 is used to carry a part of the motor.

[0053] In summary, by forming a first groove by enclosing between the rim ring in the wheel and the connected inner rim portion, the notch of the first groove is located on the side facing the axis line of the wheel hub, and the first groove is used to carry a part of the motor, so that the space on the wheel hub where the motor can be installed is enlarged in the radial direction of the wheel hub. When the space on the wheel hub where the motor can be installed is enlarged, a motor with a larger size and a larger power can be installed on the wheel hub, which helps to improve the performance of the wheel or the automobile using the wheel hub in the present application. The outer rim portion, the inner rim portion in the wheel hub, and the rim ring located between the outer rim portion and the inner rim portion along the axial direction of the wheel are three relatively independent parts, making the structural design and assembly of the outer rim portion, the inner rim portion and the rim ring in the wheel hub more flexible, and the design space of the wheel hub larger.

[0054] Figure 4 It is another schematic structure diagram of a wheel hub provided by an embodiment of the present application. Please refer to Figure 4 , in a feasible implementation manner, one side of the rim ring 020 is separated from the outer rim portion 010, and one side of the rim ring 020 is connected to the outer rim portion 010 through a first connector T.

[0055] One side of the rim ring 020 is separately arranged from the outer rim portion 010, so that the rim ring 020 and the outer rim portion 010 are two independent components, which is convenient for the rim ring 020 and the outer rim portion 010 to be flexibly designed according to actual usage requirements. For example, the rim ring 020 adapted to the size of the motor 310 can be replaced according to the size of different motors 310 installed on the hub 000. The first connecting member T facilitates the connection between the outer rim portion 010 and the rim ring 020, and also facilitates the assembly of the hub 000.

[0056] The other side of the rim ring 020 is separately arranged from the inner rim portion 030, and the other side of the rim ring 020 is connected to the inner rim portion 030 through a second connecting member.

[0057] The other side of the rim ring 020 is separately arranged from the inner rim portion 030, so that the rim ring 020 and the inner rim portion 030 are two independent components, which is convenient for the rim ring 020 and the inner rim portion 030 to be flexibly designed according to actual usage requirements. For example, the rim ring 020 and / or the inner rim portion 030 adapted to the size of the motor 310 can be replaced according to the size of different motors 310 installed on the hub 000. The second connecting member facilitates the connection between the inner rim portion 030 and the rim ring 020, and also facilitates the assembly of the hub 000.

[0058] When both sides of the rim ring 020 are separately arranged from the outer rim portion 010 and the inner rim portion 030 respectively, the designable space of the hub 000 is larger and the assembly is more flexible.

[0059] Specifically, in a feasible implementation manner, the number of the first connecting members T is multiple, and the multiple first connecting members T are all detachable and lockable connecting members. And / or, the second connecting member between the rim ring 020 and the inner rim portion 030 is solder.

[0060] When the multiple first connecting members T are all detachable and lockable connecting members, it is convenient to assemble the outer rim portion 010 and the rim ring 020. When the second connecting member is solder, the rim ring 020 and the inner rim portion 030 are welded, which can ensure the connection strength between the rim ring 020 and the inner rim portion 030.

[0061] Exemplarily, the multiple first connecting members T are all bolts or screws.

[0062] In other feasible embodiments, the first connector T between the rim ring 020 and the outer rim portion 010 is solder, and the number of the second connectors is multiple, and the multiple second connectors are all connectors that can be disassembled and locked. Alternatively, the number of the first connector T and the second connector is multiple, and both are connectors that can be disassembled and locked. Alternatively, the first connector T and the second connector are both solder, so that the rim ring 020 is welded to the outer rim portion 010 and the inner rim portion 030.

[0063] Figure 5 It is a schematic diagram of a partial rim ring structure provided in an embodiment of the present application. Figure 6 It is a schematic diagram of a rim ring structure provided in an embodiment of the present application.

[0064] Please refer to Figure 5 - Figure 6 In a feasible implementation, the rim ring 020 includes: a main body ring 021 and a first connecting ring 022 adjacently distributed along the axial direction of the hub 000. In the axial direction of the hub 000, one side of the main body ring 021 is fixedly connected to the first connecting ring 022, and the annular surface of the first connecting ring 022 intersects with the annular surface of the main body ring 021.

[0065] The first connecting ring 022 is connected to the outer rim portion 010 via a first connecting member T, and the side of the main body ring 021 away from the first connecting ring 022 is connected to the inner rim portion 030 via a second connecting member.

[0066] In the axial direction of the wheel hub 000, the rim ring 020 includes: a main body ring 021 and a first connecting ring 022. One side of the main body ring 021 is fixedly connected to the first connecting ring 022, and the other side is connected to the inner rim portion 030. The annular surface of the first connecting ring 022 intersects with the annular surface of the main body ring 021, and is connected to the outer rim portion 010 through the first connecting ring 022, so that the rim ring 020 is easily connected to the outer rim portion 010.

[0067] In order to conveniently connect the rim ring 020 and the outer wheel rim portion 010, at least part of the annular surface in the first connecting ring 022 is perpendicular to the annular surface of the main ring 021. Correspondingly, the surface in the outer wheel rim portion 010 connected to the first connecting ring 022 is parallel to at least part of the annular surface in the first connecting ring 022 to ensure the connection strength between the rim ring 020 and the outer wheel rim portion 010.

[0068] It should be noted that when at least part of the annular surface of the first connecting ring 022 is perpendicular to the annular surface of the main ring 021, the annular surface of the main ring 021 is parallel to the axis of the hub 000. The annular surface of the main ring 021 and the annular surface of the first connecting ring 022 both refer to inner and outer annular surfaces.

[0069] Exemplarily, the first connecting ring 022 includes: an inner connecting ring 0221 and an outer connecting ring 0222. The inner side of the outer connecting ring 0222 is fixedly connected to the outer side of the inner connecting ring 0221, and the outer side of the outer connecting ring 0222 is connected to the side of the main body ring 021 facing away from the inner rim portion 030.

[0070] Wherein, the ring surface of the inner connecting ring 0221 is perpendicular to the ring surface of the main body ring 021, and the ring surface of the outer connecting ring 0222 is inclined with respect to both the ring surface of the inner connecting ring 0221 and the ring surface of the main body ring 021.

[0071] Please refer to Figure 5 , in a feasible implementation manner, the rim ring 020 further includes: a second connecting ring 023. In the axial direction of the hub 000, the second connecting ring 023 is connected to the side of the main body ring 021 facing away from the first connecting ring 022, and the second connecting ring 023 is connected to the inner rim portion 030 through a second connecting member.

[0072] Wherein, the ring surface of the second connecting ring 023 intersects with the ring surface of the main body ring 021.

[0073] By the intersection of the ring surface of the second connecting ring 023 and the ring surface of the main body ring 021, it is convenient to make the axial dimension of the hub 000 more compact.

[0074] Exemplarily, the main body ring 021, the first connecting ring 022, and the second connecting ring 023 are of an integral structure.

[0075] Please refer to Figure 4 , in a feasible implementation manner, the inner rim portion 030 includes: a first ring 031, a second ring 032, and a third ring 033 connected in sequence along the axial direction of the hub 000. The first ring 031 is connected to the side of the rim ring 020 facing away from the outer rim portion 010, that is, the first ring 031 is connected to the second connecting ring 023 in the rim ring 020. The first ring 031, the second ring 032, and the third ring 033 enclose a second groove C2, and the notch of the second groove C2 is located on the side away from the axis of the hub 000.

[0076] The second groove C2 formed by enclosing the first ring 031, the second ring 032, and the third ring 033 can be used to support and fix one side of the tire 210 and perform a limiting function.

[0077] Figure 7 It is a schematic diagram of a sound-absorbing ring structure provided by an embodiment of the present application. Please refer to Figure 7 , in a feasible implementation manner, the hub 000 further includes: a sound-absorbing ring 040.

[0078] Please refer to Figure 4 ,Figure 7 The sound-absorbing ring 040 shown is sleeved and fixed on the outer side wall of the main body ring 021.

[0079] Generally, the motor 310 on the wheel hub generates noise during operation. When the wheel 200 of the wheel hub 000 of the present application travels with the vehicle, the tire 210 generates low-frequency cavity sound on a rough asphalt road. At this time, when using the wheel hub 000 of the present application, the sound-absorbing ring 040 can effectively absorb and eliminate the noise.

[0080] Exemplarily, the sound-absorbing ring 040 is a ring structure made of a material with sound-absorbing properties. For example, the sound-absorbing ring 040 is sound-absorbing cotton.

[0081] Figure 8 It is a schematic diagram of another sound-absorbing ring structure provided by an embodiment of the present application. Please refer to Figure 8 , to ensure the sound-absorbing effect of the sound-absorbing ring 040, the thickness D of the sound-absorbing ring 040 is 15 - 20 mm. Exemplarily, the thickness of the sound-absorbing ring 040 is 20 mm.

[0082] Please refer to Figure 2 , in the related art, the structure of the outer side of the rim of the wheel 200 has large undulations and is irregular, so it is impossible to paste sound-absorbing cotton for noise reduction, and it is impossible to effectively absorb the noise generated during the operation of the motor 310, resulting in poor comfort of the vehicle.

[0083] Please refer to Figure 5 , correspondingly, in a feasible implementation manner of the present application, the ring surface of the main body ring 021 in the rim is planar, and the ring surface of the main body ring 021 is parallel to the axis of the wheel hub 000.

[0084] Through the planar ring surface of the main body ring 021, it is convenient to paste strip-shaped sound-absorbing cotton on the ring surface of the main body ring 021. After the strip-shaped sound-absorbing cotton is pasted on the main body ring 021, it forms the sound-absorbing ring 040. The sound-absorbing ring 040 can effectively absorb the noise generated during the operation of the motor 310 and improve the performance of the prototype vehicle.

[0085] Exemplarily, in the axial direction of the wheel hub 000, the length L of the main body ring 021 is 90 mm to facilitate providing sufficient installation space for the sound-absorbing ring 040.

[0086] In a feasible implementation manner, the thickness of the rim ring 020 is less than or equal to the thickness of the inner rim portion 030. When the thickness of the rim ring 020 is less than or equal to the thickness of the inner rim portion 030, it is convenient to process and install the rim ring 020.

[0087] Exemplarily, the thickness of the rim ring 020 is less than the thickness of the inner rim portion 030.

[0088] In the present application, since the outer rim portion 010, the rim ring 020, and the inner rim portion 030 in the wheel hub 000 are three relatively independent parts, therefore, the outer rim portion 010, the rim ring 020, and the inner rim portion 030 can be more flexible not only in their respective structural designs but also in their respective material selections. That is, the materials of the outer rim portion 010, the rim ring 020, and the inner rim portion 030 can be the same or different.

[0089] Exemplarily, in a feasible implementation manner, the outer rim portion 010 is machined and manufactured using aluminum alloy to facilitate providing a better appearance effect. Both the rim ring 020 and the inner rim portion 030 adopt metal rigid materials to facilitate ensuring the connection effect and structural strength of the rim ring 020 and the inner rim portion 030. For example, both the rim ring 020 and the inner rim portion 030 are structures formed by stamping steel plates.

[0090] Figure 9 It is a schematic comparison diagram of the wheel hub provided by the embodiment of the present application and the wheel hub in the related art. Please refer to Figure 9 , in the rim ring 020 of the wheel hub 000 designed in the present application, it protrudes outward to form a groove structure away from the axis line of the wheel hub 000, while the rim ring of the wheel hub 100 in the related art protrudes inward to form a groove structure close to the axis line of the wheel hub 100. It can be clearly seen that the rim ring 020 in the wheel hub 000 of the present application can raise the space on the wheel hub 000 where the motor 310 can be installed, that is, the space on the wheel hub 000 where the motor 310 can be installed can be increased along the radial direction of the wheel hub 000. The height corresponding to the installation space of the motor 310 that the wheel hub 000 of the present application can raise is H, and H can be adaptively designed according to actual needs, and the present application does not make specific limitations.

[0091] Please refer to Figure 4 , in a feasible implementation manner, the wheel hub 000 further includes: a plurality of spokes 050. The plurality of spokes 050 are fixed in the annular space on the outer rim portion 010. The outer rim portion 010 and the plurality of spokes 050 cooperate to ensure the appearance shape of the wheel 200 and the installation of the tire 210.

[0092] In summary, a first groove is formed by enclosing between the rim ring in the wheel and the connected inner rim portion. The notch of the first groove is located on the side facing the axis of the hub. The first groove is used to carry a part of the motor, so that the space on the hub where the motor can be installed is enlarged along the radial direction of the hub. After the space on the hub where the motor can be installed is enlarged, a motor with a larger size and higher power can be installed on the hub, which helps to improve the performance of the wheel or the vehicle using the hub in this application. The outer rim portion, the inner rim portion in the hub, and the rim ring located between the outer rim portion and the inner rim portion along the axial direction of the wheel are three relatively independent parts, making the structural design and assembly of the outer rim portion, the inner rim portion, and the rim ring in the hub more flexible, and the design space of the hub larger.

[0093] Figure 10 is a schematic structural diagram of a wheel provided by an embodiment of the present application. Please refer to Figure 10 , another embodiment of the present application provides a wheel 200, including: the hub 000 as described in any of the previous paragraphs, and a tire 210 connected to the hub 000.

[0094] Specifically, the tire 210 has an outer tire portion 211 and an inner tire portion 212 that are axially oppositely distributed. The outer rim portion 010 is used to support the outer tire portion 211, and the inner rim portion 030 is used to support the inner tire portion 212.

[0095] Figure 11 is a schematic structural diagram of another wheel 200 provided by an embodiment of the present application. Please refer to Figure 11 , the assembly sequence of the wheel 200 in the embodiment of the present application is introduced as follows:

[0096] Install the tire 210 from left to right so that the outer rim portion 010 supports and fixes the outer tire portion 211. After the outer tire portion 211 and the outer rim portion 010 are connected, install the rim ring 020 from right to left, and connect the outer rim portion 010 and the rim ring 020 through the first connector T. After the rim ring 020 and the outer rim portion 010 are connected, an annular gap is formed between the side of the rim ring 020 away from the outer rim portion 010 and the inner tire portion 212. The strip-shaped sound-absorbing cotton enters the space between the rim ring 020 and the tire 210 through the annular gap, is fixed on the annular surface of the rim ring 020, and forms a sound-absorbing ring 040. After the sound-absorbing ring 040 is fixed, install the inner rim portion 030 from right to left, connect the rim ring 020 and the inner rim portion 030 through the second connector, and seal the annular gap. In this way, the assembly of the wheel 200 is completed.

[0097] By using the wheel 200 in the embodiment of the present application, since the outer rim portion 010, the rim ring 020, and the inner rim portion 030 in the hub 000 are three independent parts and can be installed separately one after another, in this way, the sound-absorbing ring 040 will not conflict with the installation process of the tire 210. When the installation process of the sound-absorbing ring 040 does not conflict with that of the tire 210, the limitation on the thickness of the sound-absorbing ring 040 will be smaller, which is convenient for increasing the thickness of the sound-absorbing ring 040 and improving the noise reduction performance of the sound-absorbing ring 040.

[0098] Another embodiment of the present application provides an automobile, including: an automobile chassis, a motor 310 fixed on the automobile chassis, and a wheel 200 connected to the motor 310. The wheel 200 is the wheel 200 as described above.

[0099] Exemplarily, the motor 310 installed on the hub 000 is a hub 000 motor 310. The wheel 200 is connected to the automobile chassis through a suspension system on the automobile chassis.
