They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0037] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The present invention will be described in detail with specific implementation methods to illustrate the technical solution provided by this utility model.
[0038] refer to Figure 1 As shown, this utility model provides a bicycle wheel quick-release assembly 100, which is assembled on a bicycle wheel 200. The wheel 200 has a wheel hole 201 in the center, a bearing 300 is assembled in the wheel hole 201, the bearing 300 has a bearing hole 301 in the center, the bicycle axle 400 is inserted through the bearing hole 301, and the part of the axle 400 that passes through the bearing hole 301 has a slot 401.
[0039] refer to Figure 2 As shown, the bicycle wheel quick-release assembly 100 specifically includes a cover 1, an elastic reset member 2, and a locking member 3. The cover 1 is mounted on the bearing hole 301. The locking member 3 is movably disposed between the bearing 300 and the cover 1 along the radial direction of the wheel hole 201 (as shown by the X-axis in the figure). The cover 1 has a through hole 101 for a portion of the locking member 3 to pass through. The elastic reset member 2 is disposed between the cover 1 and the locking member 3. The elastic preload of the elastic reset member 2 acts on the locking member 3 to push the locking member 3 into the slot 401, maintaining a limiting state on the wheel axle 400.
[0040] When wheel 200 is damaged and needs to be replaced, the operator only needs to press the portion of locking member 3 exposed through hole 101 to compress elastic reset member 2, offsetting the elastic preload of elastic reset member 2 on locking member 3, causing locking member 3 to leave slot 401. This releases the locking member 3 from the axle 400, allowing wheel 200 to be quickly detached from axle 400. When a new wheel 200 is installed on axle 400, first press the portion of locking member 3 exposed through hole 101 to remove the restriction of locking member 3 on axle 400, allowing axle 400 to pass through bearing hole 301 and align slot 401 with locking member 3. Then, release the push on the portion of locking member 3 exposed through hole 101, and under the elastic preload of elastic reset member 2, push locking member 3 into slot 401, locking axle 400 onto wheel 200, thus completing the quick installation of the new wheel 200.
[0041] The bicycle wheel quick-release assembly 100 provided by this utility model can disassemble and assemble the wheel 200 without the operator using other tools or screws, thereby improving the efficiency of disassembling and assembling the wheel 200, shortening the time, and having a simple structure, making it more convenient to operate, reducing the difficulty of use, and significantly improving the safety, reliability and user experience.
[0042] Specifically, refer to Figure 3 As shown, in this embodiment, the locking member 3 is a metal sheet structure, such as an iron sheet or a copper sheet, and includes a base plate 31 and a driving part 32. The driving part 32 is protruding from the side end of the base plate 31. A locking hole 311 is formed on the base plate 31, which can communicate with the bearing hole 301, so that the axle 400 can pass through the bearing hole 301 and the locking hole 311 at the same time. The opening of the slot 401 is opposite to the inner wall of the locking hole 311, and the slot 401 is annular, so that the shape of the slot 401 can be coupled with the cross-sectional shape of the inner wall of the locking hole 311, ensuring that the inner wall of the locking hole 311 can be inserted. The wheel 200 is inserted into the slot 401; the elastic reset member 2 is disposed between the cover 1 and the base plate 31; the drive part 32 is movably disposed through the through hole 101 as the part of the locking member 3 exposed in the through hole 101. By pushing the drive part 32 to slide in the through hole 101, the operator can drive the base plate 31 to compress the elastic reset member 2. At the same time, the inner wall of the locking hole 311 can gradually move away from the slot 401 until it is completely disengaged from the slot 401, thereby releasing the restriction on the axle 400 and allowing the axle 400 to exit from the bearing hole 301 and the locking hole 311, thereby realizing the separation of the wheel 200 from the axle 400.
[0043] It should be noted that the diameter of the lock hole 311 is larger than that of the bearing hole 301, ensuring that after the locking member 3 releases the limiting state of the wheel axle 400, the inner wall of the lock hole 311 can be completely separated from the slot 401, thereby ensuring that the wheel axle 400 can be smoothly withdrawn from the lock hole 311.
[0044] For more specific details, please refer to [link / reference]. Figure 3 As shown, in this embodiment, a locking tongue 312 protrudes from the inner wall of the locking hole 311. When the wheel axle 400 is in a limited position, the locking tongue 312 can be inserted into the slot 401, allowing the inner wall of the locking hole 311 to be inserted deeper. This avoids the safety risk of the inner wall of the locking hole 311 separating from the slot 401 when the elastic reset member 2 is compressed due to bumps, vibrations, etc., which could cause the wheel 200 to fall off unexpectedly. This further improves the locking stability of the wheel axle 400.
[0045] Preferably, continue to refer to Figure 3As shown, in this embodiment, the elastic reset member 2 is a compression spring; the locking member 3 also includes a plugging protrusion 33, which protrudes from the driving part 32 at both ends of the base plate 31, and the compression spring is fitted onto the plugging protrusion 33 to achieve accurate installation of the elastic reset member 2 and the locking member 3, ensuring that the central axis of the elastic reset member 2 and the central axis of the locking member 3 can coincide, thereby ensuring that the elastic preload of the elastic reset member 2 is always transmitted along the central axis of the locking member 3, avoiding the elastic reset member 2 from being subjected to off-center loading, twisting or radial movement, ensuring that the locking member 3 remains stable during reciprocating motion, and improving the reliability of the quick-release assembly.
[0046] Specifically, refer to Figure 4 As shown, the cover 1 provided in this embodiment includes an end cap 11 and a flange 12. The flange 12 is arranged around the outer circumference of the end cap 11. The end cap 11 has the through hole 101 mentioned above. The end cap 11 can seal and cover the bearing 300 to cover and protect the wheel axle 400, locking member 3 and elastic reset member 2, isolate the wheel axle 400, locking member 3 and elastic reset member 2 from the external environment, maintain a good locking relationship between locking member 3 and wheel axle 400, and avoid interference from external factors. The flange 12 has at least two spaced first connecting holes 121 arranged around the axis of the wheel hole 201; the inner wall of the wheel hole 201 has at least two spaced protrusions arranged around the axis of the wheel hole 201, each protrusion corresponding to one of the first connecting holes 121, and a second connecting hole 2011 coaxially corresponding to the first connecting hole 121 is formed on the protrusion; in addition, the quick-release assembly also includes a detachable connector that can pass through the first connecting hole 121 and connect to the second connecting hole 2011, so that the cover 1 can simultaneously seal the bearing hole 301 and the wheel hole 201, preventing dust and other impurities from entering the bearing hole 301 and the wheel hole 201 and requiring frequent cleaning. Moreover, by detachably connecting the cover 1 to the wheel 200, the quick-release assembly can be replaced between wheels 200 of the same size, improving the reusability of the quick-release assembly and thus saving usage costs.
[0047] Optionally, combined Figure 4 , Figure 5As shown, a first guide groove 302 is provided on the end face of the bearing 300 facing the cover 1; a second guide groove 111 is provided on the end face of the cover 1 facing the bearing 300. In this embodiment, the second guide groove 111 is provided on the inner wall of the end cap 11. The first guide groove 302 and the second guide groove 111 can be engaged to form a guide channel. The elastic reset member 2 is limited and disposed in the guide channel. This can further limit the compression direction of the elastic reset member 2, ensuring that when the elastic reset member 2 is compressed, the compression direction is consistent with the axial direction of the elastic reset member 2. This makes the sliding of the locking member 3 in the cover 1 smoother, reduces the feeling of obstruction during operation, and makes the connection between the elastic reset member 2, the bearing 300 and the cover 1 more precise and tight.
[0048] Preferably, the cross-sectional shape of the first guide groove 302 and the second guide groove 111 is semi-circular, so that the shape of the guide channel formed after the first guide groove 302 and the second guide groove 111 are fastened together is consistent with the shape of the elastic reset member 2, which makes the assembly stability of the elastic reset member 2 higher.
[0049] Optionally, refer to Figure 6 As shown, in this embodiment, a first mounting groove 112 is provided on the end face of the end cap 11 facing the bearing 300. The locking member 3 is disposed in the first mounting groove 112, and one side end of the first mounting groove 112 is connected to the second guide groove 111, and the other side end of the first mounting groove 112 is connected to the second guide groove 111. With the above arrangement, after the locking member 3 is placed in the first mounting groove 112, by pushing the driving part 32, the locking member 3 can be driven to move radially along the wheel hole 201 in the first mounting groove 112. At the same time, the locking member 3 can be embedded in the cover 1, the connection between the locking member 3 and the cover 1 is more compact, the overall integrity is stronger, and the extension and retraction process of the locking member 3 is more stable.
[0050] Optionally, refer to Figure 2 , Figure 6 As shown, in this embodiment, the bottom surface of the first mounting groove 112 is provided with a second mounting groove 113. The second mounting groove 113 is used to accommodate the portion of the axle 400 that passes through the bearing hole 301 and the locking hole 311. This allows the axle 400 to be placed in a limited position by the quick-release assembly, so that the portion of the axle 400 that passes through the bearing hole 301 and the locking hole 311 can be inserted into the cover 1. This helps to expose the entire slot 401 outside the bearing hole 301, making it easier for the locking member 3 to be inserted into the slot 401 and improving the quick-release efficiency.
[0051] Optionally, refer to Figure 6 , Figure 7As shown, in this embodiment, an annular limiting flange 114 protrudes from the opening edge of the second assembly groove 113. The limiting flange 114 is disposed opposite to the through hole 101, and the limiting flange 114 can be inserted between the inner wall of the lock hole 311 and the part of the wheel axle 400 that passes through the shaft hole and the lock hole 311. The limiting flange 114 limits the movement distance of the locking member 3. When the locking member 3 applies a pushing force to the elastic reset member 2, and the inner wall of the locking hole 311 of the locking member 3 abuts against the limiting flange 114, the operator can feel a noticeable resistance. This indicates that the central axis of the locking hole 311 is exactly aligned with the central axis of the bearing hole 301, which is the signal that the locking member 3 has moved into place. The locking hole 311 (specifically the locking tongue 312) completely retracts from the slot 401, allowing the wheel axle 400 to successfully transition from the limited state to the free state. This allows the wheel 200 to be quickly removed from the wheel axle 400, greatly reducing the number of times the operator needs to adjust the extension and retraction position of the locking member 3, and further improving the user experience.
[0052] refer to Figure 8 As shown, this embodiment also provides a bicycle, including a frame 500, wheels 200, and the aforementioned bicycle wheel quick-release assembly 100. The frame 500 has axles 400 at both its front and rear ends, and each axle 400 can be connected to the wheel 200 via the bicycle wheel quick-release assembly 100. By using the aforementioned bicycle wheel quick-release assembly 100, the bicycle allows for wheel 200 assembly and disassembly without the need for additional tools or screws, thereby improving the efficiency and time required for wheel 200 assembly and disassembly. Furthermore, the simple structure and convenient operation significantly enhance safety, reliability, and riding experience.
[0053] It should be further noted that this utility model does not limit the type of bicycle; the bicycle can be, for example, as shown in the figure below. Figure 8 The single-arm balance bicycle shown can also be a traditional double-arm front / rear fork bicycle, road bike, mountain bike, folding bike, or children's bike, as long as its wheel axle 400 requires detachable locking, the quick-release wheel assembly 100 of this bicycle can be used.
