Description

Technical Field

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

[0002] During operation, especially at high speeds or on rough roads, the wheels of existing vehicles often experience vibrations due to uneven road surfaces, which are transmitted to the vehicle body, affecting handling and ride comfort. Current vehicle damping solutions, in addition to optimizing the suspension system, generally also optimize wheel damping. However, current wheel damping solutions typically involve internal shock-absorbing structures within the tire. While this provides some damping effect, the overall damping performance of the wheel itself remains relatively limited. Utility Model Content

[0003] The present invention aims to improve the shock absorption effect of wheels.

[0004] To solve the above problems, this utility model provides a wheel rim, which includes a wheel rim body and a shock-absorbing structure. The inner circumferential surface of the wheel rim body is provided with a thickened protrusion structure, and the thickened protrusion structure is provided with an embedded groove. At least a portion of the shock-absorbing structure is located in the embedded groove, and the shock-absorbing structure is connected and fixed to the thickened protrusion structure.

[0005] The wheel rim provided by this utility model differs from the prior art in that the inner circumferential surface of the wheel rim body is provided with a thickened protrusion structure that is radially thickened. That is, the thickness of the wheel rim at the thickened protrusion structure is greater than the thickness at other locations. In this way, at least a portion of the shock-absorbing structure can be embedded in the thickened protrusion structure, with at least a portion of the shock-absorbing structure located in an embedded groove and connected and fixed to the thickened protrusion structure. Thus, the embedded shock-absorbing structure can exert a shock-absorbing and damping effect inside the wheel rim, thereby effectively reducing the vibration transmitted from the road surface and improving the driving comfort of the vehicle. In addition, since the shock-absorbing structure is embedded in the thickened protrusion structure, the portion of the wheel rim body without the thickened protrusion structure can still use a thinner wheel rim body, just like in the prior art, to reduce weight and ultimately achieve a good shock-absorbing effect without significantly increasing the weight of the wheel rim. Moreover, since the thickened protrusion structure is located on the inner circumferential surface of the rim body, it will not affect the installation fit between the tire and the outer circumferential surface of the rim body, nor will it cause wear to the tire. Furthermore, since the thickened protrusion structure and the shock-absorbing structure do not occupy the space between the outer circumferential surface of the rim body and the tire, it is possible to ensure that other shock-absorbing structures and / or sound-absorbing and noise-reducing structures can still be installed inside the tire. Secondly, if the shock-absorbing structure is replaced later, it can be easily and conveniently replaced without removing the tire.

[0006] Furthermore, the protruding direction of the thickened protrusion structure is the radial direction of the rim body, and the thickened protrusion structure extends circumferentially along the rim body to form a ring structure.

[0007] Furthermore, multiple embedded grooves and multiple shock-absorbing structures are provided, and multiple embedded grooves are spaced apart along the circumference of the wheel rim body on the annular structure, and multiple shock-absorbing structures are provided in one-to-one correspondence with multiple embedded grooves.

[0008] Furthermore, the embedded groove is disposed on one side of the thickened protrusion structure along the axial direction of the rim body.

[0009] Furthermore, the bottom of the recessed groove is provided with a first connecting hole, and the shock-absorbing structure includes a shock-absorbing block and a fastening structure. The shock-absorbing block is provided with a through second connecting hole. When the shock-absorbing block is placed in the recessed groove, the fastening structure is used to sequentially connect to the second connecting hole and the first connecting hole to fix the shock-absorbing block.

[0010] Furthermore, the fastening structure is an expansion screw; or, the fastening structure is a screw or bolt, and the first connecting hole is a threaded hole.

[0011] Furthermore, the fastening structure includes a threaded sleeve, a fastener, a flexible sleeve, and a clamping member. The first connecting hole is a threaded hole. The flexible sleeve is sleeved outside the threaded sleeve. The flexible sleeve and the threaded tube are used to be inserted into the second connecting hole. One end of the fastener is connected to the clamping member. The fastener is used to sequentially connect the threaded tube and the first connecting cylinder so as to compress and thicken the flexible sleeve by driving the clamping member.

[0012] This utility model also provides a wheel, characterized in that it includes the rim as described above.

[0013] Since the technological improvements and beneficial effects of the wheel are at least the same as those of the rim, the wheel will not be described in detail here.

[0014] Furthermore, the wheel also includes a hub and spokes, the hub and the rim body of the wheel rim being coaxially arranged, and one end of the spokes being connected to the rim body and the hub; wherein, the thickened protrusion structure of the rim is located on the inner circumferential surface of the rim body near the end of the spokes, and the thickened protrusion structure abuts against the spokes, and the recessed groove of the rim is provided on the side of the thickened protrusion structure away from the spokes.

[0015] This utility model also provides a vehicle, including the wheels as described above.

[0016] Since the technological improvements and beneficial effects of the vehicle are at least the same as those of the wheels, the vehicle will not be described in detail here. Attached Figure Description

Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0028] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0029] See Figure 2-5 According to an embodiment of the present utility model, a wheel rim includes a wheel rim body 1 and a shock-absorbing structure 2. The inner circumferential surface of the wheel rim body 1 is provided with a thickened protrusion structure 3. The thickened protrusion structure 3 is provided with an embedded groove 31. At least a portion of the shock-absorbing structure 2 is located in the embedded groove 31, and the shock-absorbing structure 2 is connected and fixed to the thickened protrusion structure 3.

[0030] The wheel rim provided in this embodiment differs from the prior art in that the inner circumferential surface of the wheel rim body 1 is provided with a thickened protrusion structure 3, that is, the thickness of the wheel rim at the thickened protrusion structure 3 is greater than the thickness at other locations; in this way, at least a portion of the shock-absorbing structure 2 can be embedded in the thickened protrusion structure 3, and at least a portion of the shock-absorbing structure 2 is located in the embedded groove 31 and connected and fixed to the thickened protrusion structure 3; thus, the embedded shock-absorbing structure 2 can play a shock-absorbing and damping role inside the wheel rim, thereby effectively reducing the vibration transmitted from the road surface through the wheel rim itself and improving the driving comfort of the vehicle.

[0031] Furthermore, since the damping structure 2 is embedded within the thickened protrusion structure 3, the portion of the rim body 1 without the thickened protrusion structure 3 can still utilize a thinner rim body 1, similar to existing technologies, to reduce weight. This allows for better damping performance without significantly increasing the rim's weight. Additionally, because the damping structure 2 is embedded within the thickened protrusion structure 3, which is an added structure to the existing rim body 1, the embedding of the damping structure 2 within the thickened protrusion structure 3 does not reduce the original rigidity of the rim body 1.

[0032] Furthermore, since the thickened protrusion 3 is located on the inner circumferential surface of the rim body 1, it not only does not affect the installation fit between the tire and the outer circumferential surface of the rim body 1, but also does not cause tire wear. Moreover, because the thickened protrusion 3 and the shock-absorbing structure 2 do not occupy the space between the outer circumferential surface of the rim body 1 and the tire, it ensures that other shock-absorbing structures 2 and / or sound-absorbing and noise-reducing structures can still be installed inside the tire. Secondly, if the shock-absorbing structure 2 is replaced later, it can be easily and conveniently replaced without disassembling the tire. Additionally, compared to being located on the outer circumferential surface of the rim body 1, the shock-absorbing structure 2 being located on the inner circumferential surface of the rim body 1 prevents the wheel from detaching from the rim body 1 during rotation.

[0033] Optionally, see Figure 1-4 The protruding direction of the thickened protrusion structure 3 is the radial direction of the rim body 1, and the thickened protrusion structure 3 extends circumferentially along the rim body 1 to form a ring structure.

[0034] In this embodiment, the protruding direction of the thickened protrusion structure 3, or its protruding direction, is along the radial direction of the rim body 1; and the extending direction of the thickened protrusion structure 3 is along the circumferential direction of the rim body 1 to form a ring structure; thus, the ring structure is convenient to be integrally processed with the rim body 1, and the ring structure can be integrally formed when processing the inner circle (inner circumferential surface) of the rim body 1, and the processing steps are not complicated or cumbersome.

[0035] Of course, in other embodiments, it is not excluded that the protruding direction of the thickened protrusion structure 3 may form a certain angle with the radial direction of the rim body 1. In this case, the ring structure is equivalent to a conical ring structure.

[0036] Optionally, see Figure 1-3 The embedded grooves 31 and the shock-absorbing structures 2 are respectively provided in multiple ways. The multiple embedded grooves 31 are arranged at intervals along the circumference of the wheel rim body 1 on the annular structure. The multiple shock-absorbing structures 2 are arranged one-to-one with the multiple embedded grooves 31.

[0037] In this embodiment, multiple damping structures 2 are embedded in the annular structure at intervals along the circumference of the rim body 1. Thus, regardless of the angle at which the wheel rotates, some of the vibration from the bottom surface can be absorbed by these damping structures 2, ensuring the damping effect of the rim itself. Furthermore, since the multiple damping structures 2 are evenly distributed on the annular structure, when the rim is subjected to vibration, these damping structures 2 can also ensure the uniformity of rim damping.

[0038] Optionally, see Figure 1-4 The embedded groove 31 is disposed on one side of the thickened protrusion structure 3 along the axial direction of the rim body 1.

[0039] In this embodiment, the thickened protrusion structure 3 has three sides: a first side located at one end in the protrusion direction, and two sides along the axial direction of the rim body 1, which are the second and third sides. For example, when the thickened protrusion structure 3 is an annular structure, the first side of the thickened protrusion structure 3 refers to the inner ring surface of the annular structure, that is, the side facing the central axis of the rim body 1; one axial end face of the annular structure is the second side, and the other axial end face of the annular structure is the third side.

[0040] In this embodiment, the shock-absorbing structure 2 is disposed on the second or third side. Especially when the thickened protrusion structure 3 is a ring structure, the shock-absorbing structure 2 is embedded in one axial end face of the ring structure. In this case, the embedded groove 31 is also disposed in one axial end face of the ring structure. Thus, the embedded groove 31 can be machined along the axial direction of the rim body 1, and the operating space during machining is large enough, making the forming convenient.

[0041] Furthermore, since the recessed groove 31 is machined into a ring structure along the axial direction of the rim body 1, that is, the depth direction of the recessed groove 31 is parallel to the axial direction of the rim body 1, when the shock-absorbing structure 2 needs to be installed, the shock-absorbing structure 2 can be directly installed in the recessed groove 31 along the axial direction of the rim body 1, which is simple and convenient.

[0042] In other embodiments, it is not excluded that the recessed groove 31 is disposed on the inner ring surface of the annular structure, and the shock-absorbing structure 2 is installed in the recessed groove 31 along the radial direction of the annular structure.

[0043] Optionally, see Figure 1-3 The bottom of the recessed groove 31 is provided with a first connecting hole 32. The shock-absorbing structure 2 includes a shock-absorbing block 21 and a fastening structure 22. The shock-absorbing block 21 is provided with a through second connecting hole 211. When the shock-absorbing block 21 is placed in the recessed groove 31, the fastening structure 22 is used to sequentially connect the second connecting hole 211 and the first connecting hole 32 to fix the shock-absorbing block 21.

[0044] In this embodiment, the bottom of the recessed groove 31 is provided with a first connecting hole 32, and the shock absorber 21 is provided with a through second connecting hole 211. When installing the shock absorber structure 2, the shock absorber 21 can be placed in the recessed groove 31 first, and the second connecting hole 211 of the shock absorber 21 placed in the recessed groove 31 is aligned with the first connecting hole 32. Then, the fastener 222 is sequentially connected into the second connecting hole 211 and the first connecting hole 32 to fix the shock absorber 21 in the recessed groove 31.

[0045] In this embodiment, the shock absorber 21 plays a role in absorbing and reducing shock. Therefore, preferably, the shock absorber 21 is completely placed in the recessed groove 31, that is, the shock absorber 21 is completely embedded in the thickened protrusion structure 3, and the fastener 222 can have a part exposed outside the shock absorber 21 and the recessed groove 31. Of course, the fastener 222 can be completely placed in the recessed groove 31.

[0046] In this embodiment, the shock absorber 21 can be a rubber block, which can effectively absorb and dissipate vibration energy when subjected to vibration or impact, reducing the impact on the surrounding environment. In other embodiments, the shock absorber 21 can also be made of other materials besides rubber, such as polyurethane, silicone, etc.

[0047] In this embodiment, the embedded groove 31 has a cylindrical structure, which is convenient for processing and forming. Correspondingly, the shock absorber 21 also has a cylindrical structure. In other embodiments, the cross-sectional shape of the embedded groove 31 can also be polygonal, elliptical, or other shapes. Correspondingly, the cross-sectional shape of the shock absorber 21 matches the cross-sectional shape of the embedded groove 31.

[0048] Optionally, the fastening structure 22 is an expansion screw; or, the fastening structure 22 is a screw or bolt, and the first connecting hole 32 is a threaded hole.

[0049] In one embodiment, see Figure 2The fastening structure 22 can be a simple screw or bolt. The first connecting hole 32 at the bottom of the recessed groove 31 is a threaded hole. After the screw or bolt passes through the second connecting hole 211 of the damping block 21, it is threaded into the first connecting hole 32 until the nut of the screw or bolt is pressed against the damping block 21. In this embodiment, especially when the fastening structure 22 is a screw with a pointed head (and a nut at the tail), the diameter of the portion of the screw between the pointed head and the nut at the tail can be slightly larger than the inner diameter of the second connecting hole 211. The presence of the pointed head of the screw allows it to easily enter the smaller inner diameter of the second connecting hole 211. As the screw enters the first connecting hole 32, the larger diameter screw causes the damping block 21 to expand radially, so that the damping block 21 and the thickened protrusion 3 fit tightly together until the nut at the tail is pressed against the damping block 21. This allows the damping block 21 and the thickened protrusion 3 to fit tightly together, resulting in better damping effect.

[0050] In another embodiment, the fastening structure 22 is not a simple screw or bolt, but a more complex expansion screw. It is understood that the expansion screw comprises two parts: an expansion sleeve and a bolt. The outer diameter of the expansion sleeve when not expanded can be the same as the inner diameter of the second connecting hole 211. When installing the damping structure 2, the damping block 21 is first placed in the recessed groove 31, then the expansion sleeve of the expansion screw is inserted into the second connecting hole 211 of the damping block 21, and then the bolt of the expansion screw is screwed into the expansion sleeve until the bolt is connected to the first connecting hole 32. According to the principle of the expansion screw, as the bolt is gradually screwed into the expansion sleeve, the damping block 21 expands radially to improve the damping effect.

[0051] Optionally, see Figure 5 In another embodiment, the fastening structure 22 includes a threaded sleeve 221, a fastener 222, a flexible sleeve 223, and a clamping member 224. The first connecting hole 32 is a threaded hole. The flexible sleeve 223 is sleeved outside the threaded sleeve 221. The flexible sleeve 223 and the threaded sleeve 221 are used to be inserted into the second connecting hole 211. One end of the fastener 222 is connected to the clamping member 224. The fastener 222 is used to be inserted into the threaded sleeve 221 and the first connecting hole 32 in sequence, so as to drive the clamping member 224 to compress the flexible sleeve 223 to become thicker.

[0052] In this embodiment, the fastening structure 22 includes four parts: a threaded sleeve 221, a fastener 222, a flexible sleeve 223, and a clamping member 224. The inner wall of the threaded sleeve 221 has threads, the fastener 222 is a screw or bolt that engages with the threads on the inner wall of the threaded sleeve 221, the flexible sleeve 223 is sleeved on the outside of the threaded sleeve 221, and the clamping member 224 has a ring structure. When installing the shock-absorbing structure 2, first place the threaded sleeve 221 and the flexible sleeve 223 outside the threaded sleeve 221 into the second connecting hole 211 (the inner diameter of the second connecting hole 211 can be greater than or equal to the outer diameter of the flexible sleeve 223 so that the threaded sleeve 221 and the flexible sleeve 223 outside the threaded sleeve 221 can be inserted into the second connecting hole 211). Then, put the clamping member 224 on the outside of the fastener 222, and then screw the fastener 222 into the threaded sleeve 221. As the fastener 222 is screwed in, the nut part of the fastener 222 will drive the clamping member 224 to act on the flexible sleeve 223 and axially compress the flexible sleeve 223, causing it to expand radially. This causes the shock-absorbing block 21 to expand and fit tightly with the thicker protruding structure, thereby improving the shock absorption effect.

[0053] In this embodiment, since both the damping block 21 and the flexible sleeve 223 expand, the frictional force ensures the damping structure 2 is fixed within the recessed groove 31. The first connecting hole 32 can be a threaded hole, and the fastener 222's threaded connection to this hole further ensures the damping structure 2 is fixed within the recessed groove 31. The flexible sleeve 223 can be a corrugated pipe or a deformable plastic tube, etc.

[0054] Another embodiment of this utility model provides a wheel, characterized in that it includes the rim as described above.

[0055] Since the technological improvements and beneficial effects of the wheel are at least the same as those of the rim, the wheel will not be described in detail here.

[0056] Optionally, see Figure 1 and Figure 3 The wheel also includes a hub 4 and spokes 5. The hub 4 is coaxially arranged with the rim body 1 of the wheel rim. One end of the spokes 5 is connected to the rim body 1 and the hub 4. The thickened protrusion structure 3 of the wheel rim is located on the inner circumferential surface of the rim body 1 near the end of the spokes 5, and the thickened protrusion structure 3 abuts against the spokes 5. The inner groove 31 of the wheel rim is provided on the side of the thickened protrusion structure 3 away from the spokes 5.

[0057] In addition to the rim, the wheel also includes a hub 4 for connecting to the axle, and spokes 5 connecting the hub 4 to the rim. It is understood that one function of the spokes 5 is to support the hub 4. In this embodiment, the thickened protrusion 3 is specifically located on the inner circumferential surface of the rim body 1 near the spoke 5, and the thickened protrusion 3 abuts against the spoke 5. Therefore, the thickened protrusion 3 can, to a certain extent, enhance the supporting effect of the spokes 5 on the hub 4. Furthermore, the thickened protrusion 3 and the damping structure 2 on it are located at the end of the rim near the axle, ensuring that vibrations transmitted from the ground, after passing through the rim, are only transmitted to the axle, i.e., the vehicle suspension system, after being damped by the damping structure 2. This ensures a stronger effectiveness of the rim's damping effect.

[0058] In this embodiment, the embedded groove 31 is provided on the side of the thickened protrusion 3 away from the spoke 5. In particular, when the thickened protrusion 3 is a ring structure, more embedded grooves 31 and shock-absorbing structures 2 can be provided on the 360° ring structure to improve the shock absorption effect of the rim. Along the axial direction of the rim, the annular structure has a first side and a second side that are arranged opposite to each other. When the first side of the annular structure abuts against the spoke 5, the second side of the annular structure is the side away from the spoke 5. The embedded groove 31 is on this second side, which can ensure that the design number of the inner cavity groove 31 is not limited by the spoke 5. That is, the inner cavity groove 31 can be set at any position on the second side without being affected by the spoke 5. However, if the inner cavity groove 31 is opened on the first side, since the first side faces and abuts against the spoke 5, the opening position of the inner cavity groove 31 on the first side needs to be offset from the spoke 5, which will limit the design number of the inner cavity groove 31. In addition, since the inner cavity groove 31 is set on the second side of the annular structure away from the spoke 5, it can also ensure that the installation of the shock absorption structure 2 will not be affected by the spoke 5.

[0059] A vehicle according to another embodiment of the present invention includes the wheels as described above.

[0060] Since the technological improvements and beneficial effects of the vehicle are at least the same as those of the wheels, the vehicle will not be described in detail here.

[0061] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" and "second" may explicitly or implicitly include at least one of those features.

[0062] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
