[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Refer to the attached Figure 1-7 , a bicycle frame with an air guide cover on the side in an embodiment of the utility model.

[0031] The bicycle frame includes a head tube 2, a middle tube 5, a top tube 1, and a down tube 4. The ends of the top tube 1 are respectively connected to the upper portions of the head tube 2 and the middle tube 5, and the ends of the down tube 4 are respectively connected to the lower portions of the head tube 2 and the middle tube 5. The top tube 1 is located above the down tube 4. A first air guide hood 3 is provided on both sides of the head tube 2. A first air guide hole 20 is formed between the first air guide hood 3 and the head tube 2. The first air guide hole 20 is arranged along the length of the top tube 1.

[0032] In this embodiment, by configuring the first air guide hood 3 on both sides of the head pipe 2 and utilizing the first air guide hole 20 formed between the first air guide hood 3 and the head pipe 2, the turbulent flow generated by the head pipe 2 cutting the air during bicycle riding can be guided by the first air guide hole 20 to form a smooth airflow, thereby increasing the smoothness and stability of bicycle riding, reducing wind resistance, and improving the aerodynamics of cycling.

[0033] In one embodiment, a plurality of pins 31 are provided on the first air guide cover 3 , and the head pipe 2 is provided with a socket 22 adapted for use with the pins 31 . The pins 31 are placed in the socket 22 to fix the first air guide cover 3 to the side wall of the head pipe 2 .

[0034] Specifically, in one embodiment, the number of the pins 31 and the number of the sockets 22 can be four, and the four pins 31 are respectively distributed near the four end corners of the first air duct 3 to firmly fix the first air duct 3 on the outer wall of the head pipe 2.

[0035] In one embodiment, the first air guide cover 3 is adhered to the outer wall of the head pipe 2 near the upper and lower ends by glue or double-sided tape. This structure is used in conjunction with the pins 31 to effectively increase the connection area between the first air guide cover 3 and the head pipe 2, thereby effectively increasing the stability of the first air guide cover 3 fixed to the head pipe 2.

[0036] Of course, in other embodiments, the number of the pins 31 and the jacks 22 can be 3, 5, 6, 8, etc. Alternatively, the first air guide 3 can also be fixed to the outer wall of the head pipe 2 by means of buckles, screws, glue, etc.

[0037] In one embodiment, the first air scoop 3 is provided with a plurality of air outlet holes 33 that communicate with the first air guide holes 20. These air outlet holes 33 are arranged in an array, extending along the length of the head tube 2. The air outlet holes 33 on the side away from the center tube 5 are closer to the outer wall of the head tube 2 than the air outlet holes 33 on the side closer to the center tube 5. This means that during cycling, air enters the bicycle from the end of the first air guide holes 20 away from the center tube 5, and some of the air is discharged through the air outlet holes 33. This air outlet holes 33 accelerate the exhaust flow, improving airflow.

[0038] In one embodiment, the first air scoop 3 includes a base plate 32 and a bent portion 34 formed by bending the upper and lower ends of the base plate 32 near the outer wall of the head tube 2. The pin 31 is mounted on the bent portion 34. The first air duct 20 is formed by the base plate 32, the bent portion 34, and the outer wall of the head tube 2. The head tube 2 is recessed inwardly to form a concave surface 21 at a location corresponding to the first air scoop 3. This reduces the thickness of the bicycle frame at the head tube 2 while allowing the concave surface 21, the base plate 32, and the bent portion 34 to form the first air duct 20.

[0039] In one embodiment, the bicycle frame further includes a rear fork 7 connected to the middle tube 5 and a second air guide 6 disposed above the rear fork 7. The rear fork 7 is located on the side of the middle tube 5 away from the head tube 2. The second air guide 6 is at least partially located behind the middle tube 5. The second air guide 6 is provided with a second air guide hole 62 for guiding air flow. The opening of the second air guide hole 62 is arranged along the length of the bicycle frame. By disposing the second air guide 6 at the location where the rear fork 7 and the middle tube 5 are connected, and providing the second air guide hole 62 in the second air guide 6, during bicycle riding, the airflow passing through the middle tube 5 will be smoothed by the second air guide hole 62. When the airflow passes above the connection between the middle tube 5 and the rear fork 7, the airflow will not be turbulent due to the lack of air guides. In this way, the bicycle can be ridden more stably.

[0040] In order to effectively prevent turbulence when the airflow passes above the connection between the middle tube 5 and the rear fork 7 , there are two second air guide holes 62 , which are located on both sides of the middle tube 5 .

[0041] In one embodiment, the rear fork 7 includes two support rods located on either side of the rear wheel, with two second air guide holes 62 located above the two support rods, respectively. The support rods include a first connecting rod 71 and a second connecting rod 72 connected to the first connecting rod 71. The first connecting rod 71 is connected to the rear wheel at an end remote from the second connecting rod 72, and the second connecting rod 72 is connected to the middle tube 5 at an end remote from the first connecting rod 71. The angle between the first connecting rod 71 and the second connecting rod 72 is 90°-150°, and the width of the second air guide cover 6 is consistent with the width of the rear fork 7. By forming a corner between the first connecting rod 71 and the second connecting rod 72, the distance between the two first connecting rods 71 ​​and the end of the middle tube 5 can be increased, thereby increasing the width of the rear fork 7. The width of the second air guide cover 6 is consistent with the width of the rear fork 7, thereby increasing the width of the second air guide holes 62 and better guiding the airflow.

[0042] In one embodiment, the second air guide cover 6 is detachably provided on the rear fork 7 to facilitate assembly between the second air guide cover 6 and the rear fork 7 , thereby facilitating production and manufacturing of the bicycle frame.

[0043] In one embodiment, the second air scoop 6 has a limiting opening 61 on the side away from the rear wheel. The limiting opening 61 is located between the two second air guide holes 62, and the middle tube 5 is at least partially positioned within the limiting opening 61. A hook 63 is formed on the bottom of the side away from the rear wheel, extending downward. The hook 63 has a retaining opening 64 on the side near the rear wheel. The front end of the second connecting rod 72 is positioned within the retaining opening 64. The bottom surface of the second air scoop 6 has a groove 65 that mates with the second connecting rod 72 and the first connecting rod 71. The limiting opening 61 and the groove 65 limit the left and right positions of the second air scoop 6, the retaining opening 61 limits the upper and lower positions of the second air scoop 6, and the retaining hook 63 engages with the bottom of the second connecting rod 72 to achieve installation of the second air scoop 6 on the bicycle frame. Of course, in other embodiments, the second air guide cover 6 can also be fixed by screws, adhesives, or other clips, or the second air guide cover 6 can be sleeved on the middle tube 5 and installed with the middle tube 5 by interference fit, etc. The structure of fixing the second air guide cover 5 on the rear fork 7 is not limited here.
