Abstract
Description
Technical Field
[0001] The invention relates to the field of bicycle wheel sets, and in particular to a connection structure and a connection method between spokes and a carbon fiber rim, and a bicycle wheel set. Background Art
[0002] The wheel set is the part that connects the wheel to the frame. In the bicycle structure, the power transmission and turning control of the bicycle need to be transmitted to the tire through the wheel set. It is a more important part of the bicycle system. The bicycle wheel set includes multiple components such as the rim, the hub and the spokes.
[0003] In the existing bicycle wheel set, the metal head at the end of the spoke connected to the rim is exposed outside the rim, which will increase riding resistance. The metal head is exposed to the outside for a long time, which will increase the corrosion of the metal parts at the end of the spoke. In rainy days or flooded roads, water is easy to enter the contact area between the spoke and the rim, thereby hindering riding. If the wheel set is soaked in water for a long time, it will cause air leakage, resulting in safety hazards.

DETAILED DESCRIPTION
[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0042] Embodiment 1 Refer to the attached drawings of the specification, such as Figure 1-Figure 16 As shown, the connection structure between the spokes and the carbon fiber rim proposed in the present application includes: a top cover 1, a fixing part 2, an embedded part 3 and a nut 4.
[0043] A plurality of spoke holes 61 are arranged along the circumference of the carbon fiber rim 6, and the embedded parts 3 are embedded in the spoke holes 61, and the inner wall of the embedded parts 3 is provided with internal threads 31. One or more limit blocks 32 are protrudingly arranged on the outer surface of the embedded parts 3, and the cross-sectional shape of the limit blocks 32 is non-circular to prevent the limit blocks 32 from rotating with the carbon fiber rim 6. Specifically, the cross-sectional shape of the limit blocks 32 can be polygonal, star-shaped or D-shaped. An installation step 62 is arranged in the spoke hole 61, and the position of the embedded parts 3 is limited to the bottom of the installation step 62. A threaded end 51 is arranged at the end of the spoke 5, and the end of the spoke 5 is inserted into the top cover 1, and the fixing part 2 is inserted into the spoke hole 61, and the threaded end 51 at the end of the spoke 5 is locked by the nut 4. The outer wall of the fixing part 2 is provided with an external thread 21, and the fixing part 2 is rotated into the spoke hole 61, so that the fixing part 2 is connected to the embedded part 3 through the thread. The top cover 1 is located on the external thread 21 of the fixing part 2, and the top cover 1 is made of a flexible material, specifically a rubber material, so that the edge of the top cover 1 is sealed and connected to the spoke hole 61. The upper end of the fixing part 2 is provided with a protrusion 23, and the protrusion 23 is positioned on the upper surface of the installation step 62.
[0044] The surface shape of the top cover 1 is adapted to the surface shape of the carbon fiber wheel rim 6, so that the top cover 1 and the surface of the carbon fiber wheel rim 6 have a smooth transition. A slot 22 is provided on the top of the fixing member 2, and an insertion block 11 that is adapted to the shape of the slot 22 is protruding from the bottom of the top cover 1. When the insertion block 11 is inserted into the slot 22, the fixing member 2 is tightly connected to the top cover 1. The cross-sectional shapes of the insertion block 11 and the slot 22 are non-circular. When the insertion block 11 is inserted into the slot 22, there is no relative rotation between the top cover 1 and the fixing member 2. Specifically, the cross-sectional shapes of the insertion block 11 and the slot 22 can be star-shaped, and can also be polygonal or have protrusions on the surface.
[0045] The carbon fiber rim 6 located at the spoke hole 61 is provided with a thickened reinforcement area 63, and the thickened reinforcement area 63 is formed by a protrusion of the rim toward the rim axis. By providing the rim thickened reinforcement area 63, the rim thickness in this area is increased, thereby increasing the structural strength of the connection between the carbon fiber rim 6 and the spoke 5.
[0046] The method for connecting the spokes and the carbon fiber rim proposed in the present application comprises the following steps when connecting the spokes and the carbon fiber rim: S10, pre-arranging the embedded part 3 in the carbon fiber wheel rim 6, and forming it into one piece with the carbon fiber wheel rim 6; S20, threaded end 51 is installed at the end of spoke 5; S30, the top cover 1 and the fixing member 2 are sleeved on the spoke 5, and the nut 4 is fixed to the threaded end 51; S40, rotating the fixing member 2 and inserting it into the embedded member 3 by means of a thread, until the end of the fixing member 2 is inserted into the spoke hole 61; S50 , pressing the top cover 1 sleeved on the spoke 5 toward the fixing member 2 until the edge of the top cover 1 is sealed and connected to the spoke hole 61 .
[0047] Among them, in step S40, when the fixing member 2 is rotated and inserted into the embedded member 3, the operation can be performed through the handle 7. The handle 7 includes an insertion portion 72 and a hand-held portion 71. A person holds the hand-held portion 71 to drive the insertion portion 72 to rotate. A receiving groove 73 is provided in the center of the same side of the insertion portion 72 and the hand-held portion 71. The shape of the receiving groove 73 is adapted to the shape of the spoke 5, so that the spoke 5 can be inserted into the receiving groove 73. The shape of the insertion portion 73 is adapted to the shape of the slot 22 at the top of the fixing member 2, so that the handle 7 drives the fixing member 2 to rotate during the rotation process. When the handle 7 is in use, the receiving groove 73 of the handle 7 is sleeved on the spoke 5, the insertion portion 72 of the handle 7 is inserted into the slot 22 at the top of the fixing member 2, and then the handle 7 is rotated to drive the fixing member 2 to rotate and insert into the embedded member 3.
[0048] Based on the connection structure and method of spokes and carbon fiber rims, the present application proposes a bicycle wheel set, which also includes a hub 8, a carbon fiber rim 6, and spokes 5.
[0049] The hub 8 is located in the middle of the rim, and a first flange 81 and a second flange 82 are arranged on the hub 8 opposite to each other, and threaded holes 83 are arranged on the first flange 81 and the second flange 82. Threaded ends 51 are arranged at both ends of the spoke 5, wherein the threaded end 51 at one end is connected to the carbon fiber rim 6 through the connecting structure between the spoke and the carbon fiber rim, and the threaded end 51 at the other end is connected to the threaded hole of the first flange 81 or the second flange 82. The threaded hole 83 on the first flange 81 and the second flange 82 is a through hole 831 or a blind hole 832. When the threaded hole 83 is a through hole 831, the spoke 5 is inserted into one end of the through hole 831, and the other end of the through hole 831 is blocked by a screw 521.
[0050] The spokes 5 connected to the first flange 81 are first spokes 52, and the spokes 5 connected to the second flange 82 are second spokes 53. The number of first spokes 52 is twice the number of second spokes 53, and the first spokes 52 are staggered. A plurality of spoke holes 61 are evenly distributed on the peripheral wall of the carbon fiber rim 6 in groups of three. The spacing a between each group of spoke holes 61 is the same, and the spacing between two adjacent groups of spoke holes 61 is b, and b is greater than a. Two first spokes 52 and one second spoke 53 form a group, and the second spoke 53 in the same group is located between the two first spokes 52, and the spokes 5 in the same group are connected to the spoke holes 61 in the same group.
[0051] Embodiment 2 Refer to the attached drawings of the specification, such as Fig.17As shown, compared with the bicycle wheel set of the first embodiment, the spokes 5 of this embodiment are arranged as follows: Each spoke hole 61 is evenly distributed on the peripheral wall of the carbon fiber rim 6, and the spacing c between two adjacent spoke holes 61 is the same. The carbon fiber rim 6 includes a plurality of thickened reinforcement areas 63 and a plurality of low frame areas 64, and the thickened reinforcement areas 63 and the low frame areas 64 are alternately arranged. The second spoke 53 is connected to the thickened reinforcement area 63, and the first spoke 52 is connected to the low frame area 64.
[0052] In this wheel set in which three spokes 5 are grouped together and the ratio of the number of spokes 5 connected to the first flange 81 and the second flange 82 on the hub 8 is 2:1, the force borne by the second spokes 53 with a smaller number needs to balance the force borne by the first spokes 52 with a larger number, and each second spoke 53 is subjected to a greater lateral pressure, which makes the carbon fiber rim 6 prone to the problem of deflection. Therefore, by providing a thickened reinforcement area 63 at the position connected to the second spoke 53 on the carbon fiber rim 6, the thickness of the rim is increased, thereby increasing the rigidity of the second spoke 53, so that the second spoke 53 can withstand greater pressure.
[0053] In summary, the connection structure and method of the spoke and carbon fiber rim and the bicycle wheel set proposed in the present application have the following advantages: 1. The ends of the spokes 5 are hidden in the carbon fiber rim 6, which reduces the wind resistance of the wheel set during rotation. A top cover 1, a fixing part 2, an embedded part 3 and a nut 4 are arranged between the spokes 5 and the carbon fiber rim 6, so that the connection between the spokes 5 and the carbon fiber rim 6 is sealed. When encountering rainy days or water accumulation, water cannot enter the inside of the rim, thereby avoiding the problem of increasing the weight of the traditional wheel set due to water ingress and long-term immersion in water causing riding obstruction and wheel set leakage. At the same time, the ends of the spokes 5 are also protected to prevent the metal at the ends from being corroded by rainwater.
[0054] 2. By hiding the ends of the spokes 5 inside the rim, during the inflation process, the gas entering the rim will not exert a large force on the ends of the spokes 5, thereby reducing the degree of tension variation of the spokes 5 and ensuring the tension stability and rigidity of the wheel set.
[0055] 3. When installing the spokes 5 and the carbon fiber rim 6, they must be installed in the order provided in this application. In order to facilitate the installation, this application provides a special handle 7 for installation. The receiving groove 73 provided on the handle 7 can fit the shape of the spoke 5, and the spoke 5 can be inserted into the handle 7 without affecting the rotational installation of the handle 7 on the fixing part 2.
[0056] 4. The spokes 5 are tightened with the first flange 81 and the second flange 82 on the hub 8 by threads, so as to strengthen the tightness of the connection between the spokes 5 and the hub 8 and prevent the spokes 5 from falling off the hub 8. Compared with the structure in which the spokes 5 are overlapped on the hub 8, in the present application, when the wheel set is subjected to a large impact, the spokes 5 will not fall off or be damaged, thereby ensuring the safe riding of the wheel set.
[0057] 5. A plurality of thickened reinforcement areas 63 are provided on the surface of the carbon fiber rim 6 to increase the structural strength of the connection between the carbon fiber rim 6 and the spokes 5 .
[0058] 6. There are multiple arrangements of the spokes 5 on the carbon fiber rim 6, such as two of the arrangements described in Embodiment 1 and Embodiment 2 of the present application; the installation structure of the spokes 5 proposed in Embodiment 2 increases the thickness of the rim at the location where the spokes 5 are connected by setting a thickened reinforcement area 63 on the carbon fiber rim 6 at the location where the spokes 5 are connected, thereby increasing the rigidity of the second spokes 53 and allowing the second spokes 53 to withstand greater pressure.
[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
