[0045] Embodiment 1:

[0046] See also Figure 1-4 The present invention provides a technical solution: a mud cover structure for a bicycle chain, comprising:

[0047] A first side cover 1, which is mounted on one side of a bicycle chain 100, comprises a first retaining ring 11, a first chainring cover 12, a first flywheel cover 13 and a first transition plate 14 connected to the first chainring cover 12 and the first flywheel cover 13, wherein the first chainring cover 12 and the first flywheel cover 13 are respectively mounted on one side of a bicycle chainring group and a flywheel, wherein the first chainring cover 12 and the first flywheel cover 13 are both cone structures with straight generatrixes, and the first transition plate 14 is a V-shaped structure with straight side surfaces, wherein the first retaining ring 11 and the first transition plate 14 are covered on the chain 100, and an air inlet 143 is provided on the first transition plate 14;

[0048] The second side cover 2 is mounted on the other side of the bicycle, and includes a second stop ring 21, a second chainring cover 22, a second flywheel cover 23, and a second transition plate 24 for docking the second chainring cover 22 and the second flywheel cover 23. The second chainring cover 22 and the second flywheel cover 23 are respectively mounted on the other side of the bicycle chainring group and the flywheel. The second chainring cover 22 and the second flywheel cover 23 are both cone structures with a generatrix curve. The second transition plate 24 is a V-shaped structure with a curved side. A mud discharge port 243 is provided on the second transition plate 24. The two side covers can be perforated to facilitate docking of the front and rear derailleurs used for chain shifting on a variable-speed bicycle with the chain.

[0049] The bicycle chain mud guard of the present invention adopts a sandwich structure design in which two side covers cooperate with the chain, which can block mud, water and the like flying toward the chain on both sides of the bicycle, and avoid the problem of the chain being contaminated and causing its movement to be blocked and unstable. The two side covers are designed with different surface aerodynamics. The aerodynamic parameters of the first side cover on the side where the bicycle chain is assembled are worse than those of the second side cover. When riding a bicycle, the air flow velocity flowing through the surface of the second side cover is higher than that on the first side cover. The air inlet and mud outlet are respectively arranged on the two side covers, so that an air flow from the first side cover to the second side cover is formed on both sides. The bicycle crosswind formed by the air flow will blow the dirt flying toward the chain directly toward the second side cover and discharge it from the mud guard cover through the mud outlet, thereby realizing the chain's anti-mud and mud-blocking functions. When the design is cleaned, the inner cavity of the first side cover and the chain are clean. It is only necessary to rinse the outer side of the first side cover and remove the second side cover with a simple structure and method for docking with the bicycle accessories for cleaning, thereby improving the cleaning efficiency and operation convenience of the mud guard cover.

[0050] In this embodiment, the aerodynamically differentiated designs of the surfaces of the two side covers are specifically as follows: the first chainring cover 12 includes a first mounting plate 121, and a first conical arc plate 122 connecting the first retaining ring 11 and the first mounting plate 121, and the generatrix of the first conical arc plate 122 is straight; the second chainring cover 22 includes a second mounting plate 221, and a second conical arc plate 222 connecting the second retaining ring 21 and the second mounting plate 221, and the generatrix of the second conical arc plate 222 is an outwardly convex arc.

[0051] The first mounting plate 121 and the second mounting plate 221 are both provided with mounting grooves 123 , and the mounting grooves 123 are provided with first mounting holes 124 and second mounting holes 125 which are respectively positioned to dock with the outer side of the bicycle crankset and the bracket bolts.

[0052] The first flywheel cover 13 includes a third mounting plate 131 and a third conical arc plate 132 with a straight generatrix, a third mounting hole 133 for docking a bicycle flywheel is arranged in the center of the third mounting plate 131, and the second flywheel cover 23 includes a fourth conical arc plate 231 with a generatrix in an outwardly convex arc shape, and a fourth mounting hole 232 for docking a bicycle flywheel is arranged in the center of the fourth conical arc plate 231. The above mounting hole design can improve the assembly strength of the mud guard on the bicycle, the chain, the crankset, and the outer side of the flywheel.

[0053] The first transition plate 14 includes a first connecting plate 141 and a straight side plate 142, the air inlet 143 is arranged in the center of the first connecting plate 141, the second transition plate 24 includes a second connecting plate 241 and an arc-shaped side plate 242 protruding outward, the second connecting plate 241 is connected to the second crankcase cover 22, and the mud discharge port 243 is formed between the second connecting plate 241 and the arc-shaped side plates 242 on both sides. Among them, based on the need for one side of the second side cover 2 to bear the main mud guard mud discharge function, the staggered design of the second connecting plate 241 on the second side cover 2 ensures that when riding a bicycle, the feet of a person on one side of the second side cover 2 will not come into contact with the mud and dirt flying out of the mud discharge port 243 when stepping on the bicycle pedal, thereby improving the cleanliness of riding.

[0054] The working principle of a mud cover structure applied to a bicycle chain in the present embodiment includes: by differentiating the aerodynamic parameters of the conical arc plates on the two side covers, when the bicycle is riding, the air flow velocity flowing through the surface of the second side cover 2 is higher than that on the first side cover 1, and by respectively arranging an air inlet 143 and a mud discharge port 243 on the two side covers, an air flow is formed on both sides from the first side cover 1 to the second side cover 2. The bicycle crosswind formed by the air flow will blow the dirt flying toward the chain 100 directly toward the second side cover 2 and discharge it from the mud cover through the mud discharge port 243, thereby realizing the anti-mud and mud-blocking functions of the chain.

[0055] Embodiment 2:

[0056] See also Figure 1-2On the basis of the above-mentioned embodiment 1, due to the different designs of the aerodynamic parameters of the two side covers and the staggered settings of the air inlet 143 and the mud discharge port 243 in the embodiment 1, the crosswind acting on the mud guard cover structure causes the bicycle to be always affected by the crosswind when riding, which may make the bicycle difficult to control and the riding stability insufficient. Therefore, it is necessary to offset the force transmitted by the mud guard cover structure to the bicycle. Preferably, a flow stabilizing component 5 is integrally provided on the upper and lower sides of the first side cover 1, and a curved raised strip 51 is provided on the outer side of the flow stabilizing component 5, and the curved raised strip 51 is smoothly connected to the side edge of the first side cover 1 through an extension block 52, and a wedge-shaped surface 53 is provided on the inner side of the flow stabilizing component 5, and the wedge-shaped surface 53 gradually extends inward along the direction from the first flywheel cover 13 to the first chainring cover 12.

[0057] The working principle of the anti-mud cover structure for bicycle chains in this embodiment includes: Figure 1 As shown, when riding, the design of the two side covers makes the mud guard cover and the bicycle subject to a first wind force to the right, and due to the setting of the curved raised strip 51, the airflow on the left side of the upper and lower edges of the mud guard cover is higher than that on the right side, so that the upper and lower edges of the mud guard cover are subjected to a second wind force to the left opposite to the first wind force, thereby achieving the offset of the force transmitted to the bicycle by the mud guard cover; based on the staggered setting of the air inlet 143 and the mud discharge port 243, the wedge-shaped surface 53 on the side of the flow stabilizing component 5 subject to the wind force is set, so that the second wind force formed on the mud guard cover is specifically directed to the left front (with the direction of the bicycle when riding as a reference), and the staggered setting of the air inlet 143 and the mud discharge port 243 makes the second wind force direction directed to the right rear, thereby achieving precise offset of the force, ensuring the chain anti-mud and mud-blocking functions of the mud guard cover while greatly reducing the instability of bicycle riding caused by it.

[0058] Embodiment three:

[0059] See also Figure 1 On the basis of the above embodiment 1, preferably, a reinforcing plate 25 is provided inside the second retaining ring 21, and the end of the reinforcing plate 25 is screwed or clamped on the first side cover 1. This design is mainly used to improve the assembly strength of the sandwich structure composed of the two side covers and the chain.

[0060] Embodiment 4:

[0061] See also Figure 5On the basis of the above-mentioned embodiment 1, in order to clean the dirt splashed onto the chain 100 when the bicycle stops or there is no wind or low wind, preferably, a vibration cleaning component is arranged on the first retaining ring 11, and the vibration cleaning component includes a folding plate component 3 and a beating rod component 4, and the beating rod component 4 includes a plurality of beating single rods, and the folding plate component 3 includes a plurality of positioning plates 31 and a linkage plate 32 rotatably connected to the two sides of the positioning plate 31 through a hinge shaft 33, and the positioning plate 31 is assembled and positioned one by one with the beating single rod, and a guide column 34 is arranged on the central outer side of the linkage plate 32, and the guide column 34 is slidably arranged in the slide groove 112 of the inner guide rail 111 of the first retaining ring 11, and a second elastic block 35 is arranged on the outer side of the positioning plate 31.

[0062] The beating single rod includes a rod 41 positioned on the inner side of the positioning plate 31, and a sleeve 42 connected to the end of the rod 41. The C-shaped or O-shaped internal sleeve of the sleeve 42 is sleeved on the outer side of the chain 100. A limit plate 43 is arranged on the outer side of the sleeve 42. A first elastic block 113 corresponding to the limit plate 43 is arranged on the inner side of the first retaining ring 11. The first elastic block 113 is arranged on the outer side of the guide rail 111 in parallel and of equal length.

[0063] The above-mentioned structural design can be driven and used when the bicycle is moving or stationary. Its mechanism is mainly that when the chain 100 is subjected to external vibration transmission, the bicycle shifts gears, etc., the chain 100 abuts against the beating rod assembly 4 to form a force, and then, the reciprocating vibration type dirt cleaning of the chain 100 can be achieved through multiple beating single rods and the folding plate assembly 3, which is more effective when riding, thereby realizing the cleaning of the chain 100 without disassembly, and further improving the mud blocking and anti-mud effect of the mud guard cover on the chain 100.

[0064] The working principle of a mud cover structure applied to a bicycle chain in the present embodiment specifically includes: due to external vibration transmission, bicycle speed change and gear shifting, the chain 100 abuts against the beating rod assembly 4 to form a force, thereby transmitting the initial kinetic energy to the vibration cleaning assembly, and the chain 100 acts on the upper or lower side of the beating single rod sleeve, pushing the beating single rod located at a high position to move downward, and the beating single rod located at a low position to move upward, and the positioning plate 31 is subjected to the force, and cooperates with the linkage plate 32 and the guide column 34 slidingly set in the slide groove 112 to realize the linkage of each beating single rod, and the second elastic block 35 on the inner side of the positioning plate 31 abuts against the first retaining ring 11 to perform elastic pre-tightening of the vibration cleaning assembly structure activity, and the first elastic block 113 cooperates with the limiting plate 43 to elastically support the downwardly moving beating rod assembly 4, and through the above two elastic structure designs, the reciprocating impact, vibration and cleaning of each beating single rod sleeve of the vibration cleaning assembly on the chain 100 are realized. The vibration cleaning component can be used to reciprocate and clean the chain while riding a bicycle. Compared with the common brush cleaning method, it is more suitable for cleaning high-speed running chains, further ensuring the anti-mud and mud-blocking effect of the mud guard cover.

[0065] In summary, due to the adoption of the above technical solution, the anti-mud cover structure for a bicycle chain in this embodiment has the following beneficial effects compared with the prior art:

[0066] 1. The bicycle chain mud guard of the present invention adopts a sandwich structure design in which two side covers cooperate with the chain, which can block mud, water, etc. flying toward the chain on both sides of the bicycle, and avoid the problem of its activity being blocked and unstable due to the pollution of the chain. The two side covers are designed with different surface aerodynamics. The aerodynamic parameters of the first side cover on the side where the bicycle chain is assembled are worse than those of the second side cover. When riding a bicycle, the air flow velocity flowing through the surface of the second side cover is higher than that on the first side cover. The air inlet and mud outlet are respectively arranged on the two side covers, so that an air flow from the first side cover to the second side cover is formed on both sides. The bicycle crosswind formed by the air flow will blow the dirt flying toward the chain directly toward the second side cover and discharge it from the mud guard cover through the mud outlet, thereby realizing the anti-mud and mud-blocking functions of the chain. When the design is cleaned, the inner cavity of the first side cover and the chain are clean. It is only necessary to rinse the outer side of the first side cover and remove the second side cover with a simple structure and method for docking with the bicycle accessories for cleaning, thereby improving the cleaning efficiency and operation convenience of the mud guard cover.

[0067] 2. By setting up the flow stabilizing component, the wind force on the mud guard cover can be offset, ensuring the anti-mud and mud-blocking functions of the chain of the mud guard cover, while greatly reducing the instability of bicycle riding caused by this; the vibration cleaning component can reciprocate and vibrate the chain and clean it when riding a bicycle. Compared with the common brush cleaning method, it is more suitable for cleaning high-speed running chains, further ensuring the anti-mud and mud-blocking effects of the mud guard cover.
