Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a wheel and a vehicle. Background Technology

[0002] As an important component of the drive system of electric vehicles or other types of mobility vehicles, the hub motor is generally installed inside the wheel rim. The hub motor is housed in the space between the wheel rim and the end cap through the cooperation of the end cap and the end cap. During use, the tires need to be replaced due to road conditions and the age of the vehicle. When replacing the tires, both the hub motor and the wheel hub need to be removed. The wheel hub cannot be removed alone, which makes replacing the wheel hub or tires take a lot of time.

[0003] As can be seen from the above, the existing technology has the problem of inconvenient wheel hub removal. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a wheel with a hub that is easy to disassemble.

[0005] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0006] A wheel includes: a hub; and a motor assembly, at least a portion of which is housed within the hub, and the motor assembly having a motor end detachably connected to the hub. By partially housing the motor assembly within the hub and detachably connecting the hub to the motor end of the motor assembly, the motor assembly can drive the hub to rotate during wheel use. Furthermore, when removing the hub, only the connection between the hub and the motor end needs to be disconnected to remove the hub individually. This avoids the time-consuming process of removing the entire motor assembly from the vehicle and removing it from the hub, significantly saving time when changing hubs or tires.

[0007] In some embodiments, the motor assembly includes a housing portion, with a motor end located at one end of the housing portion, and the outer peripheral surface of the housing portion engaging with the inner annular surface of the wheel rim. This engagement between the housing portion and the wheel rim facilitates the positioning and installation of the motor assembly and the wheel rim, and also simplifies the fabrication of the corresponding structure.

[0008] In some embodiments, the inner circumferential surface of the rim is provided with a plurality of first protrusions spaced apart circumferentially, and a first receiving groove is formed between two adjacent first protrusions; the outer circumferential surface of the housing is provided with one or more second protrusions spaced apart circumferentially, and the second protrusions are received within the first receiving grooves. By providing a corresponding arrangement of the first receiving grooves and the second protrusions, rapid positioning of the rim and the housing can be achieved.

[0009] In some embodiments, a second receiving groove is formed between two adjacent second protrusions, and a first protrusion is received within the second receiving groove. The plurality of first protrusions are correspondingly arranged with the plurality of second receiving grooves; the plurality of second protrusions are correspondingly arranged with the plurality of first receiving grooves. This method of corresponding first and second protrusions and second receiving grooves improves the fit between the rim and the housing, ensuring a good connection even after prolonged use of the housing and rim, where some protrusions may wear.

[0010] In some embodiments, the motor assembly includes a housing portion, an end cover, and a motor. The housing portion has an opening, and the end cover seals the opening and connects to the housing portion to form a space for accommodating the motor. The end cover has a plurality of alternating first mounting holes and a plurality of second mounting holes along its circumference. The first mounting holes are for connection to the rim of a wheel hub, and the second mounting holes are for connection to the housing portion. By providing a plurality of alternating first mounting holes and a plurality of second mounting holes on the end cover, the end cover can be sealed while simultaneously connecting to the rim. When the rim needs to be disassembled and replaced, it is not necessary to separate the end cover from the housing portion, thus improving the speed of rim replacement.

[0011] In some embodiments, the motor assembly includes a housing portion, an end cap, and a motor. The housing portion has an opening, and the end cap seals the opening and is connected to the housing portion to form a space for accommodating the motor. The end cap is the end of the motor and is connected to the rim of the wheel hub. The connection between the rim and the end cap allows the motor assembly to be partially housed within the rim, and the motor end to be connected to one side of the rim, facilitating rim maintenance.

[0012] In some embodiments, the hub includes a rim and spokes, with the spokes disposed on one side of the rim. The motor assembly includes a housing portion, with a motor end located at one end of the housing portion, and one end of the housing portion connected to the spokes. By providing spokes, the structural strength of the rim can be enhanced, and the connection between the hub and the motor assembly is improved by having both ends of the housing portion connected to the rim and spokes, respectively.

[0013] In some embodiments, the wheel further includes a rocker arm for connecting the motor assembly to the vehicle. The rocker arm is a single unit and is driven to the motor shaft of the motor assembly. The motor end and the rocker arm are located on the same side of the wheel hub; or the motor end and the rocker arm are located on opposite sides of the wheel hub. The rocker arm's drive connection to the motor shaft enables the wheel to rotate relative to the vehicle. When the motor end is located on the same side of the wheel hub as the rocker arm, the motor end is connected to the housing portion via an end cap. When the motor end and the rocker arm are located on opposite sides of the wheel hub, the motor end is the end of the housing portion furthest from the rocker arm.

[0014] In some embodiments, the motor assembly includes a housing portion, an end cap, and a motor. The housing portion has an opening, and the end cap seals the opening and is connected to the housing portion to form a space for accommodating the motor. The end cap serves as the motor end, and the motor end and the rocker arm are located on the same side of the hub. By using the end cap as the motor end and positioning it on the same side of the hub as the rocker arm, it facilitates the removal of the hub.

[0015] In some embodiments, the wheel hub includes a rim and spokes, with the spokes disposed on one side of the rim. The motor assembly includes a housing portion, a motor end portion located at one end of the housing portion, and one end of the housing portion connected to the spokes. The motor end portion and the rocker arm are located on opposite sides of the wheel hub. The connection between the motor assembly's motor shaft and the rocker arm, and the connection between the motor assembly's housing portion and the spokes, allows the wheel hub to rotate relative to the vehicle and facilitates disassembly and maintenance.

[0016] This utility model also provides a vehicle, including a frame and the aforementioned wheel, with one end of a rocker arm of the wheel connected to the frame. The rocker arm connecting the wheel to the frame enables the wheel to be connected to the frame and rotate relative to the frame.

[0017] This utility model has the following beneficial effects: by partially housing the motor assembly inside the wheel hub, and detachably connecting the wheel hub to the motor end of the motor assembly, the motor assembly can drive the wheel hub to rotate when the wheel is in use. When disassembling the wheel hub, it is only necessary to disconnect the connection between the wheel hub and the motor end to remove the wheel hub separately, thereby avoiding the time wasted in removing the entire motor assembly from the vehicle and removing the motor assembly from the wheel hub. This greatly saves time in replacing wheel hubs or tires and solves the problem of inconvenient wheel hub disassembly in the prior art. Attached Figure Description

[0034] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0035] To address the problem of inconvenient wheel hub removal in existing technologies, this utility model provides a wheel and a vehicle.

[0036] like Figures 1 to 6 As shown, this utility model provides a vehicle. The vehicle includes a frame and wheels. Each wheel includes a hub 10, a motor assembly 20, and a rocker arm 30. The motor assembly 20 is partially disposed inside the hub 10. One end of the rocker arm 30 is connected to the drive end of the motor assembly 20, and the other end is connected to the frame, thereby realizing the connection between the hub 10 and the frame and enabling it to rotate relative to the frame.

[0037] In some embodiments, the number of rocker arms 30 is one. Since the rocker arm 30 is provided only on one side of the wheel hub 10, the wheel hub 10 can be removed directly without disassembling the rocker arm 30 and the motor assembly 20 after the wheel hub 10 is disconnected from the motor assembly 20, thereby avoiding the need to disassemble the motor assembly 20 and greatly improving the convenience of vehicle maintenance.

[0038] The wheels will now be explained in detail.

[0039] In some embodiments, such as Figures 1 to 6 As shown, the wheel includes a hub 10 and a motor assembly 20. At least a portion of the motor assembly 20 is housed in the hub 10, and the motor assembly 20 has a motor end 21 that is detachably connected to the hub 10.

[0040] By partially housing the motor assembly 20 within the wheel hub 10 and detachably connecting the wheel hub 10 to the motor end 21 of the motor assembly 20, the motor assembly 20 can drive the wheel hub 10 to rotate when the wheel is in use. When removing the wheel hub 10, it is only necessary to disconnect the connection between the wheel hub 10 and the motor end 21 to remove the wheel hub 10 separately. This avoids the time wasted in removing the entire motor assembly 20 from the vehicle and removing the motor assembly 20 from the wheel hub 10, thus greatly saving time when replacing the wheel hub 10 or the tire.

[0041] It should be noted that the motor end 21 in this utility model does not refer to a specific structural component itself, but rather defines the structure at the axial end position of the motor assembly 20. Figure 1 For example, in Figure 1 In the illustrated embodiment, motor end 21 refers to end cap 23 of motor assembly 20; Figure 4 For example, motor end 21 refers to the end face of housing portion 22 of motor assembly 20. That is, motor end 21 is part of motor assembly 20 and located at the end of motor assembly 20, but motor end 21 can be end cover 23 or the end face of housing portion 22. The specific choice needs to be considered in conjunction with the actual application scenario.

[0042] In this utility model, since there is ample operating space at the motor end 21, the wheel hub 10 can be disassembled and assembled by operating at the motor end 21, thereby greatly improving the convenience of maintenance.

[0043] The different implementations of the motor end 21 will be described in detail below.

[0044] In some embodiments, motor end 21 refers to end cap 23 of motor assembly 20. For example... Figures 1 to 4As shown, the hub 10 includes a rim 11, and the motor assembly 20 includes a housing portion 22, an end cap 23, and a motor 24. The housing portion 22 has an opening 25, and the end cap 23 is sealed at the opening 25 and connected to the housing portion 22 to form a space for accommodating the motor 24. The end cap 23 is connected to the rim 11 of the hub 10. The connection between the rim 11 and the end cap 23 allows the motor assembly 20 to be partially housed within the rim 11, and the motor end 21 to be connected to one side of the rim 11, facilitating maintenance of the rim 11.

[0045] Specifically, the inner diameter of the rim 11 is adapted to the housing portion 22, and one end of the housing portion 22 is a connecting end. Figure 2 End cap 23 is also provided at one end of the left side of the middle housing 22. Figure 2 The left side of the middle housing 22, and the connecting end is detachably connected to the end cover 23.

[0046] In some embodiments, the wheel further includes a plurality of connectors 40, with the end cap 23 connected to the housing portion 22 via a portion of the connectors 40. Simultaneously, the end cap 23 is fixed to the wheel hub 10 via another portion of the connectors 40. If only the wheel hub 10 needs to be disassembled, only the portion of the connectors 40 connecting the end cap 23 and the wheel hub 10 needs to be removed, without needing to operate the portion of the connectors 40 connecting the end cap 23 and the housing portion 22.

[0047] In some embodiments, such as Figure 2 and Figure 4 As shown, the end cap 23 has a plurality of alternating first mounting holes 231 and a plurality of second mounting holes 232 along its circumference. The first mounting holes 231 are used to connect with the rim 11 of the hub 10, and the second mounting holes 232 are used to connect with the housing portion 22. By providing a plurality of alternating first mounting holes 231 and a plurality of second mounting holes 232 on the end cap 23, the end cap 23 can seal the opening 25 of the housing portion 22 while simultaneously connecting with the rim 11. When it is necessary to disassemble and replace the rim 11, it is not necessary to separate the end cap 23 from the housing portion 22, thereby improving the speed of rim 11 replacement.

[0048] Specifically, the first mounting hole 231 and the second mounting hole 232 are located at the edge of the end cap 23. The connector 40 passes through the first mounting hole 231 and the second mounting hole 232 respectively and connects to the first connecting hole 50 on the housing part 22 and the second connecting hole 13 on the rim 11. When it is necessary to replace the tire or the rim 10, the rim 11 can be detached from the housing part 22 simply by disassembling the connector 40 corresponding to the second mounting hole 232.

[0049] In some embodiments, such as Figure 2 and Figure 4As shown, the inner circumferential surface of the rim 11 is provided with a plurality of first protrusions 111 spaced apart along the circumference, and a first receiving groove 112 is formed between two adjacent first protrusions 111. The outer circumferential surface of the housing portion 22 is provided with one or more second protrusions 221 spaced apart along the circumference, and the second protrusions 221 are received within the first receiving grooves 112. By setting the first receiving grooves 112 and the second protrusions 221 in a corresponding manner, rapid positioning of the rim 11 and the housing portion 22 can be achieved.

[0050] Specifically, the first connecting hole 50 is located at one end of the second protrusion 221 facing the end cap 23, and the second connecting hole 13 is located at one end of the first protrusion 111 facing the end cap 23. Both the first connecting hole 50 and the second connecting hole 13 are internally threaded holes. Figure 2 In the middle, the length of the first protrusion 111 is slightly less than the axial length of the rim 11, and the second protrusion 221 is provided at one end of the housing portion 22 near the end cover 23. That is, the rim 11 is locked and engaged with one end of the housing portion 22, and the other end of the housing portion 22 extends out of the rim 11 (see reference). Figure 1 ).

[0051] In some embodiments, such as Figure 2 and Figure 4 As shown, a second receiving groove 222 is formed between two adjacent second protrusions 221, and a first protrusion 111 is received within the second receiving groove 222. The plurality of first protrusions 111 are arranged in a one-to-one correspondence with the plurality of second receiving grooves 222. The plurality of second protrusions 221 are arranged in a one-to-one correspondence with the plurality of first receiving grooves 112. This correspondence between the first protrusions 111 and the second receiving grooves 222, as well as the correspondence between the second protrusions 221 and the first receiving grooves 112, improves the fit between the rim 11 and the housing portion 22. Even after prolonged use, if some of the protrusions wear, the connection effect can still be maintained.

[0052] Specifically, the first protruding structure 111 and the second receiving groove 222 are adapted to each other, and the second protruding structure 221 is adapted to the first receiving groove 112. Both the side of the first protruding structure 111 facing the second receiving groove 222 and the side of the second protruding structure 221 facing the first receiving groove 112 are arc-shaped surfaces, thus adapting to the inner ring surface structure of the rim 11 and the outer peripheral surface of the housing portion 22. Through the mutual interlocking of the first protruding structure 111 and the second protruding structure 221, precise alignment and stable connection between the housing portion 22 and the rim 11 are achieved, further enhancing the connection strength and stability between the motor housing and the rim 11, while ensuring ease of assembly and disassembly.

[0053] In some embodiments not shown, the spacing between two adjacent first protrusions 111 is not the same, thus forming multiple first receiving grooves 112 of different sizes. Some of the first receiving grooves 112 correspond to one second protrusion 221, and other first receiving grooves 112 correspond to multiple second protrusions 221. The specific arrangement can be selected according to actual needs.

[0054] The following section will further explain the wheel structure of the end cover 23 as the motor end 21, in conjunction with the rocker arm 30.

[0055] In some embodiments, such as Figures 3 to 4 As shown, the rocker arm 30 is a single unit and is drivenly connected to the motor shaft 241 of the motor assembly 20. The end cap 23 is the motor end 21, and the motor end 21 and the rocker arm 30 are located on the same side of the hub 10.

[0056] Specifically, after the motor 24 is installed inside the housing 22, the motor shaft 241 extends out from the clearance hole 233 on the end cover 23 and connects with the rocker arm 30, thereby realizing the connection between the wheel hub 10 and the frame.

[0057] In some embodiments, to facilitate the connection between the housing portion 22 and the rim 11, and to ensure that the rim 11 can rotate under the drive of the motor assembly 20, the motor end 21 is located at one end of the housing portion 22, and the outer peripheral surface of the housing portion 22 is provided in a concave-convex fit with the inner annular surface of the rim 11 of the hub 10. This concave-convex fit between the housing portion 22 and the rim 11 facilitates the positioning and installation of the motor assembly 20 and the hub 10, and also facilitates the fabrication of the corresponding structure.

[0058] Specifically, when end cap 23 serves as the motor end 21, it is used as... Figure 4 For example, the rim 11 and the end cap 23 are connected by a connector 40. Disassembly requires removing the connector 40 from the rocker arm 30. The diameter of the motor end 21 is smaller than the diameter of the second protruding structure 221, facilitating the removal of the hub 10. Simultaneously, the sealing performance of the end cap 23 protects the motor 24, making installation and disassembly simple and easy.

[0059] Another implementation will be provided below, in which the motor end 21 and the rocker arm 30 are respectively arranged on opposite sides of the rim 11.

[0060] In some embodiments, such as Figures 5 to 6As shown, in order to improve the structural strength of the hub 10 and the connection between the hub 10 and the motor assembly 20, the hub 10 includes a rim 11 and a spoke 12. The spoke 12 is located on one side of the rim 11, and the motor end 21 is located at one end of the housing portion 22 and is connected to the spoke 12. By providing the spoke 12, the structural strength of the rim 11 can be enhanced, thereby improving the connection between the hub 10 and the motor assembly 20.

[0061] In other words, when it is necessary to remove the wheel hub 10, it is only necessary to separate the motor end 21 from the wheel spokes 12, and the wheel hub 10 can be directly removed from the motor assembly 20. Therefore, although Figure 5 , 6 The structure of the middle wheel and Figure 1 , 2 The wheels shown have different structures, but they all utilize the method of connecting the motor end 21 to the wheel hub 10, thereby enabling quick assembly and disassembly of the wheel hub 10.

[0062] Specifically, the spokes 12 have a spoke-type structure, and the center of the spokes 12 is connected to the motor end 21 on the housing 22 via a partial connector 40, that is, the spokes 12 are connected to the end of the housing 22 away from the end cap 23. The other part of the connector 40 is used to fix the end cap 23 to the housing 22.

[0063] In some embodiments, the edge of the spoke 12 is integrally formed or welded to the edge of the rim 11, achieving a stable connection between the motor assembly 20 and the hub 10. At the same time, using the spoke 12 as a connector simplifies the installation structure between the motor assembly 20 and the frame.

[0064] In some embodiments, the spoke 12 includes a connecting portion and a strip-shaped portion extending radially along the connecting portion, the strip-shaped portion being connected to the edge of the rim 11.

[0065] In some embodiments not shown, the spokes 12 are of a spoke-plate structure.

[0066] exist Figure 5 and Figure 6 In the illustrated embodiment, the rocker arm 30 (not shown) and the end cap 23 are both located on the same side of the rim 11, but compared to Figure 1 , 2 In one embodiment, the end cap 23 no longer serves as the motor end 21. Instead, the end of the housing portion 22 away from the end cap 23 serves as the motor end 21 and is connected to the spokes 12 of the hub 10. The motor end 21 and the rocker arm 30 are located on opposite sides of the hub 10.

[0067] Specifically, after the hub 10 is fitted onto the housing portion 22, it is connected to the motor end portion 21 via a partial connector 40. That is, the spokes 12 of the hub 10 are connected to the motor end portion 21 via the partial connector 40. In other words, the end of the housing portion 22 furthest from the end cover 23 is connected to the spokes 12, allowing for quick disassembly of the hub 10 by removing the connector 40 connecting the spokes 12 and the housing portion 22. The other part of the connector 40 connects the end cover 23 and the housing portion 22. In this case, disassembling the connector 40 only requires removing the spokes 12, facilitating operation. The arrangement of the motor end portion 21 and the rocker arm 30 on opposite sides of the hub 10 achieves a stable connection between the motor assembly 20 and the hub 10, while also optimizing the wheel layout and improving vehicle handling and stability.

[0068] As can be seen from the above embodiments, regardless of whether the motor end 21 is the end cap 23 or one end of the housing 22, the connection between the motor assembly 20 and the frame will not be interfered with when disassembling the wheel hub 10, enabling quick replacement and reducing maintenance time. In other words, the improvement of this invention lies in the connection between the wheel hub 10 and the motor end 21 for easy disassembly; the disassembly method varies depending on the location of the motor end 21.

[0069] This utility model has the following beneficial effects: by partially housing the motor assembly 20 inside the wheel hub 10, and detachably connecting the wheel hub 10 to the motor end 21 of the motor assembly 20, the motor assembly 20 can drive the wheel hub 10 to rotate when the wheel is in use. When disassembling the wheel hub 10, it is only necessary to disconnect the connection between the wheel hub 10 and the motor end 21 to remove the wheel hub 10 separately, thereby avoiding the time wasted in removing the entire motor assembly 20 from the vehicle and removing the motor assembly 20 from the wheel hub 10, thus greatly saving the time of replacing the wheel hub 10 or the tire.
