Description

Technical Field

[0001] This utility model relates to the field of mountain bikes, and in particular to a lightweight aluminum alloy mountain bike frame. Background Technology

[0002] All-terrain vehicles (ATVs), also known as ATVs, are vehicles suitable for all terrains. ATVs are characterized by their simple structure, practicality, and excellent off-road performance. Therefore, ATVs are primarily found on beaches or valley roads. On soft sand, the wide tires of ATVs increase the contact area with the ground, generating greater friction. Combined with unique tire treads, this prevents the tires from spinning and slipping, further enhancing the driving experience. They can easily overcome obstacles in valleys, riverbeds, forest trails, streams, and even the harsher deserts. Therefore, to operate in harsh conditions such as beaches, riverbeds, forest trails, streams, or deserts, ATVs must possess excellent structural strength, stability, and lightweight design. The frame, as the main structure of the vehicle, has structural strength and stability that are decisive factors in determining the vehicle's performance.

[0003] A search revealed a mountain bike frame with patent publication number CN206552168U, comprising a front triangle, a center beam, and a rear triangle. The front triangle and the rear triangle are connected as one unit by the center beam. A seat gas spring is mounted on the center beam, with an adjustment handle installed on one side of the movable end of the seat gas spring. A seat is mounted on the top of the movable end of the seat gas spring, and a handlebar gas spring is located at the front end of the front triangle. However, the above structure has the following shortcomings: due to the lack of a cushioning structure, the entire mountain bike frame does not provide good comfort. Therefore, a lightweight aluminum alloy mountain bike frame is proposed. Utility Model Content

[0004] Therefore, it is necessary to address the technical problem of the lack of shock absorption and cushioning structures, which results in poor comfort for the entire mountain bike frame. This is addressed by providing a lightweight aluminum alloy mountain bike frame, comprising: a main stem and a cushioning device. A crossbar is provided on the top periphery of the main stem, and a diagonal bar is provided on the bottom periphery of the main stem. A fork mounting tube is provided at one end of the crossbar. A hinge seat is provided on the periphery of the diagonal bar. Two sets of hinge plates are symmetrically hinged to the periphery of the main stem, and a connecting plate is provided on the upper surface of both sets of hinge plates. The cushioning device includes a hollow tube, with a sleeve fitted around its periphery. The upper surface of the hollow tube... The sleeve is equipped with an upper hinge block and a lower hinge block on its bottom surface. A hydraulic damper is installed inside the sleeve, and a spring is sleeved on the circumferential side of the hydraulic damper. A second hinge seat is installed on the circumferential side of the bottom end of the main rod. A third slant bar is hinged to one end of the second hinge seat. A second slant bar is hinged to one end of the connecting plate. A connecting rod is installed on the bottom surface of the second slant bar. An installation hole is opened on the upper surface of the main rod, and a positioning block is installed on the inner wall of the installation hole. A threaded hole is opened on the circumferential side of the top end of the main rod, and an insertion rod is installed inside the installation hole. Several limiting holes are equidistantly opened on the circumferential side of the insertion rod, and a sliding groove is opened on the circumferential side of the insertion rod.

[0005] In one embodiment, one end of the slash bar is fixedly connected to the circumferential side of the fork mounting cylinder, the bottom surface of the connecting rod is fixedly connected to the upper surface of the slash bar, the top end of the hydraulic damper is fixedly connected to the upper surface of the inner wall of the hollow tube, and the bottom surface of the hydraulic damper is fixedly connected to the bottom surface of the inner wall of the sleeve.

[0006] In one embodiment, the top end of the spring is fixedly connected to the upper surface of the inner wall of the hollow tube, the bottom end of the spring is fixedly connected to the bottom surface of the inner wall of the sleeve, the upper hinge block is hinged to the other end of the connecting plate, the lower hinge block is hinged to the hinge seat, the insertion rod is slidably engaged with the mounting hole, a cushion is provided at the top end of the insertion rod, the shape and size of the sliding groove are adapted to the positioning block, the shape and size of the limiting hole are adapted to the threaded hole, bolts are inserted into the limiting hole and the threaded hole, the threaded hole is threadedly engaged with the bolt, and the limiting hole and the threaded hole are fixed by bolts.

[0007] In operation, the aforementioned lightweight aluminum alloy mountain bike frame allows for the rotation of bolts. These bolts engage with threaded holes, disengaging from the threaded holes and limiting holes on the side of the insert rod. This allows the insert rod to be pulled upwards and moved within the mounting hole. The insert rod is guided by a sliding groove and guide block on its side, preventing the insert rod from rotating with the saddle during riding and compromising safety. Several limiting holes on the side of the insert rod allow for adjustment based on individual height. When the entire mountain bike frame experiences bumps, the hinge points at the three ends of the diagonal bar and the two hinge joints will act as the base. Point 3, through the connecting rod, pushes slant bar 2 diagonally upward. Slant bar 2, through its hinge to one end of the connecting plate and with the hinge point of the main rod and the hinge plate as the origin, presses down the other end of the connecting plate. The other end of the connecting plate, through its hinge to the upper hinge block, further presses down the hollow tube. The downward pressing of the hollow tube not only transmits the force generated during bumps to the hydraulic damper for absorption, but also compresses the spring during the pressing process. The spring compression, through the hydraulic damper, further absorbs the force generated during bumps, thereby improving the comfort during riding. The hollow tube and sleeve can protect the spring and hydraulic damper. Attached Figure Description

[0017] Please refer to the following: Figures 1 to 4 This utility model provides a lightweight aluminum alloy mountain bike frame, including: a main pole 1 and a buffer device 2. A crossbar 10 is provided on the top periphery of the main pole 1, and a diagonal bar 101 is provided on the bottom periphery of the main pole 1. A fork mounting tube 102 is provided at one end of the crossbar 10. A hinge seat 103 is provided on the periphery of the diagonal bar 101. Two sets of hinge plates 1050 are symmetrically hinged to the periphery of the main pole 1. A connecting plate 105 is provided on the upper surface of both sets of hinge plates 1050. The buffer device 2 includes a hollow tube 201. The hollow tube 201 is fitted with a sleeve 202 around its periphery. The upper surface of the hollow tube 201 is provided with an upper hinge block 2010, and the bottom surface of the sleeve 202 is provided with a lower hinge block 2020. A hydraulic damper 203 is provided inside the sleeve 202. A spring 204 is fitted around the periphery of the hydraulic damper 203. A hinge seat 2 104 is provided around the bottom periphery of the main rod 1. A diagonal bar 3 12 is hinged to one end of the hinge seat 2 104. A diagonal bar 2 11 is hinged to one end of the connecting plate 105. A connecting rod 13 is provided on the bottom surface of the diagonal bar 2 11.

[0018] Furthermore, the upper surface of the main rod 1 is provided with a mounting hole 106, the inner wall of the mounting hole 106 is provided with a positioning block 1060, the top peripheral side of the main rod 1 is provided with a threaded hole 107, the mounting hole 106 is provided with an insert rod 3, the peripheral side of the insert rod 3 is provided with a plurality of limiting holes 301 at equal intervals, and the peripheral side of the insert rod 3 is provided with a sliding groove 303.

[0019] Furthermore, one end of the slant bar 101 is fixedly connected to the circumferential side of the fork mounting cylinder 102, the bottom surface of the connecting rod 13 is fixedly connected to the upper surface of the slant bar 12, the top end of the hydraulic damper 203 is fixedly connected to the upper surface of the inner wall of the hollow tube 201, and the bottom surface of the hydraulic damper 203 is fixedly connected to the bottom surface of the inner wall of the sleeve 202.

[0020] Furthermore, the top end of the spring 204 is fixedly connected to the upper surface of the inner wall of the hollow tube 201, the bottom end of the spring 204 is fixedly connected to the bottom surface of the inner wall of the sleeve 202, the upper hinge block 2010 is hinged to the other end of the connecting plate 105, and the lower hinge block 2020 is hinged to the hinge seat 103.

[0021] Furthermore, the insertion rod 3 slides into the mounting hole 106, and a seat 302 is provided at the top of the insertion rod 3. The shape and size of the sliding groove 303 are adapted to the positioning block 1060, and the shape and size of the limiting hole 301 are adapted to the threaded hole 107. Bolts 108 are inserted into the limiting hole 301 and the threaded hole 107, and the threaded hole 107 and the bolts 108 are threadedly engaged. The limiting hole 301 and the threaded hole 107 are fixed by the bolts 108.

[0022] It should be noted that during operation, the aforementioned lightweight aluminum alloy mountain bike frame can be rotated by turning bolt 108. Bolt 108 engages with threaded hole 107, thereby disengaging from threaded hole 107 and limiting hole 301 on the side of the insert rod 3. Then, by pulling upwards, insert rod 3 moves within mounting hole 106. It is guided by sliding groove 303 on the side of insert rod 3 and positioning block 1060, preventing insert rod 3 from rotating with the seat 302 during riding, thus ensuring riding safety. The limiting holes 301 on the side of insert rod 3 allow for adjustment according to different rider heights. When the entire mountain bike frame experiences bumps, the frame will rotate with the hinge point between one end of diagonal bar 3 12 and hinge seat 2 104 as the origin. 12. The connecting rod 13 pushes the second slant bar 11 diagonally upward. The second slant bar 11 is hinged to one end of the connecting plate 105 and takes the hinge point of the main rod 1 and the hinge plate 1050 as the origin, pressing down the other end of the connecting plate 105. The other end of the connecting plate 105 is hinged to the upper hinge block 2010, which in turn presses down the hollow tube 201. The downward pressing of the hollow tube 201 not only transmits the force generated during bumps to the hydraulic damper 203 for absorption, but also squeezes the spring 204 during the pressing process. The compression of the spring 204 further absorbs the force generated during bumps through the hydraulic damper 203, thereby improving the comfort during riding. The hollow tube 201 and the sleeve 202 can protect the spring 204 and the hydraulic damper 203.

[0023] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
