Technical Field

[0001] This application relates to the field of bicycle accessory technology, and in particular to a bicycle mudguard assembly. Background Technology

[0002] Currently, with the improvement of people's living standards, cycling has become a healthy way of life for riders to exercise. As an important accessory of bicycles, the mudguard is mainly used to prevent mud and water from splashing onto the rider.

[0003] Existing mudguards are usually fixed directly to the bicycle frame with screws and other fasteners. When it is sunny, the mudguards need to be removed to reduce weight, or when it is in a complex road condition such as mountain biking, the mudguards need to be removed to avoid safety issues. However, the removal of mudguards requires special tools, which makes the removal and replacement process cumbersome. Utility Model Content

[0004] To help solve the technical problem of facilitating the disassembly or replacement of mudguards, this application provides a bicycle mudguard assembly, which adopts the following technical solution:

[0005] A bicycle mudguard assembly includes a mounting member, a support member, and a mudguard. The mounting member has a mounting portion for mounting onto a bicycle frame. The support member is slidably and fixedly connected to the mudguard. The assembly also includes a connector, one end of which is rotatably fixed to the end of the support member away from the mudguard. The end of the connector away from the support member has a insertion hole. One end of the mounting member has a insertion portion, which is detachably and fixedly inserted into the insertion hole.

[0006] By adopting the above technical solution, the mounting part of the mounting component is fixedly installed on the bicycle frame, one end of the connector is rotatably fixed to the support, the support is slidably fixedly connected to the mudguard, the connector is provided with a plug hole, the mounting part is provided with a plug part, and the plug part is detachably fixedly plugged into the plug hole. By plugging and unplugging the plug hole of the connector, the assembled connector, support and mudguard and mounting component can be quickly installed and disassembled, and the mudguard assembly can be easily disassembled or replaced.

[0007] Optionally, a magnetic element is provided on the insertion hole or the insertion part, and a magnetic attracting element is provided on another part to attract the magnetic element. When the insertion part is inserted into the insertion hole, the magnetic element and the magnetic attracting element attract and abut against each other.

[0008] By adopting the above technical solution, a magnetic component is set on the insertion hole or insertion part, and a magnetic suction component is set on another component to attract the magnetic component. The magnetic component and the magnetic suction component attract and abut against each other, which improves the firmness of the connection after the insertion hole and insertion part are inserted. At the same time, the connecting part and the mounting part can be easily and quickly separated after force is applied, which facilitates the disassembly or installation of the mudguard.

[0009] Optionally, the insertion hole is a polygonal blind hole, the insertion part is a polygonal cylinder adapted to the polygonal blind hole, the magnetic suction element is fixedly installed at the bottom of the insertion hole, and the magnetic element is fixedly installed at the end of the insertion part.

[0010] By adopting the above technical solution, the insertion hole is set as a polygonal blind hole, and the insertion part is set as a polygonal column that matches the polygon, so as to prevent the insertion hole and the insertion part from rotating relative to each other after insertion, thereby improving the firmness and reliability of the mudguard installation relative to the wheel.

[0011] Optionally, the polygonal blind hole is a blind hole formed by any of 3 to 9 sides, the polygonal blind hole is a conical blind hole with the opening end larger than the bottom end, and the polygonal cylinder is a conical cylinder adapted to the conical blind hole.

[0012] By adopting the above technical solution, the polygonal blind hole has 3 to 9 sides for easy processing and manufacturing. The polygonal blind hole is a conical blind hole with the opening end larger than the bottom end. The polygonal cylinder is a conical cylinder that matches the conical blind hole. This increases the insertion gap between the insertion hole and the insertion part during insertion. After insertion, the conical surface of the conical blind hole matches the conical surface of the conical cylinder. This ensures the reliability of the operation after insertion and also improves the convenience of insertion and removal operations.

[0013] Optionally, the mudguard and the support member are slidably connected on one side and have a pair of spaced-apart tracks, each track having an inward groove. The support member has guide portions on both sides near the end of the mudguard that can slide within the grooves.

[0014] By adopting the above technical solution, the mudguard is provided with a pair of spaced-apart tracks with inward grooves. The support member is provided with guide parts on both sides near the end of the mudguard that can slide in the grooves, which facilitates the adjustment of the connection position between the support member and the mudguard, and makes it easy to adjust the position of the mudguard relative to the bicycle wheel. At the same time, it also makes the mudguard suitable for different bicycle frames.

[0015] Optionally, the channel has multiple first protrusions facing each other, and the guide portion has multiple second protrusions facing away from each other. When the guide portion slides in the channel, the first protrusions and the second protrusions rub against each other.

[0016] By adopting the above technical solution, the relative position of the guide part in the channel can be precisely adjusted through the frictional contact between the first protrusion and the second protrusion, so that the mudguard is located in the optimal position of the bicycle wheel.

[0017] Optionally, the mudguard and the support member are provided with a fixing structure that is connected to each other, so that the guide part can be fixed at any position in the channel.

[0018] By adopting the above technical solution, and by providing a fixed structure that connects the mudguard and the support, it is convenient to fix the mudguard and the support in their adjusted positions, thereby improving the reliability of the installation.

[0019] Optionally, the fixing structure includes a lead screw fixedly connected to the mudguard, the support member is provided with an elongated hole aligned with the length direction of the channel, the lead screw passes through the elongated hole, and a knob is placed at the end of the support member away from the mudguard. The knob is provided with a nut threadedly connected to the lead screw, and tightening the nut causes the support member to press against the mudguard.

[0020] By adopting the above technical solution, the mudguard is equipped with a lead screw, the support is provided with an elongated hole for the lead screw to pass through, and the knob is provided with a nut that is threaded to the lead screw. By rotating the knob, the lead screw and the nut are pressed together to tighten the mudguard and the support, which helps to improve the convenience of fixing or loosening the support and the mudguard.

[0021] Optionally, the connector has a double-ear seat at one end near the support member. The double-ear seat has a first through hole, and a plurality of first teeth are radially arranged on the two end faces of the first through hole inwardly along the axis. The support member has an ear end at one end near the connector. The ear end has a second through hole, and a plurality of second teeth are radially arranged on the two end faces of the ear end. The ear end passes through the double-ear seat so that the first through hole and the second through hole are coaxial. A first fastener passes through the first through hole and the second through hole from one end of the double-ear seat, and a first nut threadedly connected to the first fastener is installed from the other end. When the first fastener and the first nut do not apply force to the double-ear seat, the tooth tip spacing of the first teeth on the two end faces of the double-ear seat is greater than the tooth tip spacing of the second teeth on the two end faces of the ear end. When the first fastener and the first nut press the double-ear seat, a plurality of first teeth are embedded between a plurality of second teeth.

[0022] By adopting the above technical solution, tightening the first fastener and the first nut causes several first teeth to embed between several second teeth, improving the firmness and reliability of the connection between the connector and the support. Loosening the first fastener and the first nut causes the tooth tip spacing of the first teeth to be greater than that of the second teeth, disengaging the first teeth from the second teeth. This facilitates adjusting the angle between the connector and the support, thereby ensuring that the mudguard and the wheel are at the optimal angle.

[0023] Optionally, the mounting part includes a strap for tightening the bicycle frame. One end of the strap is a free end, and the other end is a fixed end. The free end and the fixed end are spaced apart. The fixed end is fixedly connected to the insertion part. The free end has a third through hole, and the fixed end has a fourth through hole coaxial with the third through hole. A second fastener passes through the free end or the fixed end, and a second nut threadedly connected to the second fastener is installed at the other end. Tightening the second fastener or the second nut presses the free end and the fixed end together, causing the strap to clamp the bicycle frame.

[0024] By adopting the above technical solution, tightening the second fastener and the second nut presses the free end and the fixed end together, thereby clamping the strap onto the bicycle frame and facilitating the installation of the bicycle mudguard assembly onto the bicycle frame.

It is simple and convenient to disassemble or replace the mudguard 3 assembly.

[0047] Reference Figure 2 and Figure 3 A magnetic component 121 is provided on the insertion hole 41 or the insertion part 12. The magnetic component 121 is made of a permanent magnet strong magnetic material. Another component is provided with a magnetic suction component 411 that attracts the magnetic component 121. The magnetic suction component 411 can be made of permanent magnet material or iron material. Any material that can be firmly attracted by permanent magnet strong magnetic material is acceptable. When the insertion part 12 is inserted into the insertion hole 41, the magnetic component 121 and the magnetic suction component 411 attract and abut against each other, which improves the firmness of the connection between the insertion hole 41 and the insertion part 12 after insertion. At the same time, the connecting part 4 and the mounting part 1 can be easily and quickly separated after force is applied, which facilitates the disassembly or installation of the mudguard 3.

[0048] Reference Figure 4 The insertion hole 41 is a polygonal blind hole 412, and the insertion part 12 is a polygonal column 122 adapted to the polygonal blind hole 412. The magnetic suction component 411 is fixedly installed at the bottom of the insertion hole 41, and the magnetic component 121 is fixedly installed at the end of the insertion part 12.

The insertion gap between the insertion hole 41 and the insertion part 12 is increased during insertion. After insertion, the conical surface of the conical blind hole is adapted to the conical surface of the conical prism. This ensures the reliability of the operation after insertion and also improves the convenience of insertion and removal operations.

[0050] Reference Figure 5 The mudguard 3 and the support member 2 are slidably connected on one side and have a pair of spaced-apart tracks, each track having an inward groove 31. The support member 2 has guide parts 21 that can slide in the groove 31 on both sides near the end of the mudguard 3. The mudguard 3 has a pair of spaced-apart tracks with inward grooves 31. The support member 2 has guide parts 21 that can slide in the groove 31 on both sides near the end of the mudguard 3. This makes it easy to adjust the connection position between the support member 2 and the mudguard 3, and to adjust the position of the mudguard 3 relative to the bicycle wheel. It also makes the mudguard 3 suitable for different bicycle frames.

[0051] Reference Figure 5 Multiple first protrusions 311 are arranged facing each other in the channel 31, and multiple second protrusions 211 are arranged opposite each other in the guide part 21. When the guide part 21 slides in the channel 31, the first protrusions 311 and the second protrusions 211 rub against each other. Through the frictional contact between the first protrusions 311 and the second protrusions 211, the shapes of the first protrusions 311 and the second protrusions 211 are arc-shaped in this embodiment of the application. Other embodiments of this application are not limited. Any shape that can increase friction after the first protrusions 311 and the second protrusions 211 abut against each other is acceptable. This allows for precise adjustment of the relative position of the guide part 21 in the channel 31, so that the mudguard 3 is located in the optimal position of the bicycle wheel.

[0052] Reference Figure 5 and Figure 6 The mudguard 3 and the support member 2 are provided with a fixing structure that is connected to each other, so that the guide part 21 can be fixed at any position in the channel 31. By providing a fixing structure that is connected to each other on the mudguard 3 and the support member 2, it is convenient to fix the mudguard 3 and the support member 2 in the adjusted position, thereby improving the reliability of the installation.

[0053] Reference Figure 5 and Figure 6The fixing structure includes a lead screw 32 fixedly connected to the mudguard 3. In this embodiment, the lead screw 32 may have a polygonal head. The mudguard 3 has a hole adapted to the polygonal head. The rotation of the lead screw 32 is restricted by inserting the polygonal head into the polygonal hole of the mudguard 3. In other embodiments of this application, the lead screw 32 can also be fixedly connected to the mudguard 3 by bonding, welding or embedding. The support member 2 has an elongated hole 22 that is consistent with the length direction of the channel 31. The lead screw 32 passes through the elongated hole 22. A slot 22 is provided, and a knob 33 is located at the end of the support member 2 away from the mudguard 3. The knob 33 is provided with a nut 331 that is threadedly connected to the lead screw 32. Tightening the nut 331 causes the support member 2 to press the mudguard 3. The mudguard 3 is provided with a lead screw 32. The support member 2 is provided with a slot 22 for the lead screw 32 to pass through. The knob 33 is provided with a nut 331 that is threadedly connected to the lead screw 32. By rotating the knob 33, the lead screw 32 and the nut 331 press the mudguard 3 and the support member 2 together, which helps to improve the convenience of fixing or loosening the support member 2 and the mudguard 3.

[0054] Reference Figure 2 and Figure 5 The connector 4 has a double-ear seat 42 near the support 2. The double-ear seat 42 has a first through hole 421. Several first teeth 422 are radially arranged on both ends of the first through hole 421. The support 2 has an ear end 23 near the connector 4. The ear end 23 has a second through hole 231. Several second teeth 232 are radially arranged on both ends of the ear end 23. The ear end 23 passes through the double-ear seat 42 so that the first through hole 421 and the second through hole 231 are coaxial. A first fastening member 5 passes through the first through hole 421 and the second through hole 231 from one end of the double-ear seat 42. A first nut 6 is threaded to the first fastening member 5 from the other end. When the first fastening member 5 and the first nut 6 are not under force on the double-ear seat 42, the first teeth on both ends of the double-ear seat 42... The tooth tip spacing of part 422 is greater than the tooth tip spacing of the second tooth part 232 on both ends of the ear end 23. When the first fastener 5 and the first nut 6 press the double ear seat 42, several first teeth 422 are embedded between several second teeth 232. By tightening the first fastener 5 and the first nut 6, several first teeth 422 are embedded between several second teeth 232, which improves the firmness and reliability of the connection between the connector 4 and the support 2. When the first fastener 5 and the first nut 6 are loosened, the tooth tip spacing of the first teeth 422 is greater than the tooth tip spacing of the second teeth 232, which makes the first teeth 422 and the second teeth 232 disengage, making it convenient to adjust the angle between the connector 4 and the support 2, thereby making the mudguard 3 and the wheel at the optimal angle.

[0055] Reference Figure 5The mounting part 11 includes a strap 111 for tightening the bicycle frame. One end of the strap 111 is a free end 112, and the other end is a fixed end 113. The free end 112 and the fixed end 113 are spaced apart. The fixed end 113 is fixedly connected to the insertion part 12. The free end 112 is provided with a third through hole 1121, and the fixed end 113 is provided with a fourth through hole 1131 coaxial with the third through hole 1121. A second through hole 1131 passes through either the free end 112 or the fixed end 113. The fastener 7 has a second nut 8 threadedly connected to the second fastener 7 at one end. Tightening the second fastener 7 or the second nut 8 presses the free end 112 and the fixed end 113, thereby clamping the strap 111 onto the bicycle frame. By tightening the second fastener 7 and the second nut 8, the second fastener 7 and the second nut 8 press the free end 112 and the fixed end 113, thereby clamping the strap 111 onto the bicycle frame, making it convenient to install the bicycle mudguard 3 assembly onto the bicycle frame.

[0056] The installation and adjustment process of a bicycle mudguard assembly is as follows: Loosen the second fastener 7 and the second nut 8 to free the strap 111, put the strap 111 onto the bicycle frame, roughly adjust the position of the mudguard 3 relative to the length and height of the bicycle, tighten the second fastener 7 and the second nut 8 to fix the mounting part 1 to the bicycle frame, loosen the first fastener 5 and the first nut 6 to disengage the first tooth 422 from the second tooth 232, rotate the support 2 to adjust the angle of the mudguard 3 relative to the bicycle wheel, and after determining the appropriate position, tighten the first fastener 5 and the first nut 6 to press the double ear seat 42, so that the first tooth 422 is embedded. The second tooth 232 prevents the support member 2 from rotating. Loosen the knob 33 and move the mudguard 3 so that the guide part 21 slides relative to the groove 31, so that the mudguard 3 is in a suitable position on the wheel in the length direction of the bicycle. Tighten the knob 33 to fix the mudguard 3 to the support member 2. When it is necessary to remove or replace the mudguard 3, apply an upward force to the connector 4 so that the insertion hole 41 of the connector 4 is disengaged from the insertion part 12 on the mounting part 1. The connector 4, support member 2 and mudguard 3 assembly are completely removed from the mounting part 1. When replacing the mudguard 3, make sure the mudguard 3 is directly above the wheel and insert the insertion hole 41 on the connector 4 into the insertion part 12 of the mounting part 1.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
