Obviously, the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0031] As Figure 1 - Figure 5As shown in the figure, an adaptive suspension device for a bicycle frame provided in this embodiment includes a main frame 1, a front beam frame 2, and a rear beam frame 3.

The damping shock-absorbing unit 8 includes a fixed cylinder 81, a sleeved cylinder 82, a connecting rod 84, and a working piston 85. A main oil storage tank 86 and a secondary oil storage tank 87 are opened inside the fixed cylinder 81, and the main oil storage tank 86 is communicated with the secondary oil storage tank 87 through a connecting through hole 88. A fixed piston 10 is fixedly installed inside the connecting through hole 88. An adaptive adjustment unit 9 is arranged on the side of the fixed piston 10 away from the main oil storage tank 86, and the adaptive adjustment unit 9 is fixedly connected to the fixed cylinder 81 through a mounting block 11. When in use, by arranging the damping shock-absorbing unit 8 between the shock-absorbing connecting plate 4 and the front beam frame 2 and connecting the shock-absorbing connecting plate 4 to the rear beam frame 3 to form a whole, it is convenient to improve the overall shock-absorbing ability. The shock absorption is achieved through the cooperation between the fixed cylinder 81, the sleeved cylinder 82, the connecting rod 84, the working piston 85, and the main oil storage tank 86. When the riding environment is poor or the rider's weight is too large, resulting in a large impact force on the frame, a high-pressure area will be formed at the position where the connecting through hole 88 contacts the main oil storage tank 86, so that the damping oil will push open the adaptive adjustment unit 9 and pass through the fixed piston 10 into the interior of the secondary oil storage tank 87, reducing the shock-absorbing burden of the damping shock-absorbing unit 8, thereby further improving the shock-absorbing effect of the damping shock-absorbing unit 8. That is, the device can achieve adaptive vibration adjustment according to the road conditions and the rider's weight, thus significantly improving the smoothness and comfort of riding.

[0032] In this embodiment, as Figure 3 and 4 shown, the adaptive adjustment unit 9 includes a sealing block 92 that fits with the fixed piston 10.

The abutting block 94 is fixedly connected to the sealing block 92 through an adjustment spring 93, and the outer wall of the side of the abutting block 94 away from the adjustment spring 93 abuts against the lower end of the mounting block 11. When in use, by utilizing the deformation characteristics of the adjustment spring 93, it is convenient to adjust the position of the sealing block 92 so that the sealing block 92 can fit with the fixed piston 10 under normal circumstances to block the connecting through hole 88, and when the riding environment is poor or the rider's weight is too large, resulting in a large impact force on the frame, the sealing block 92 can be pushed open by the damping oil.

[0033] In this embodiment, as Figure 5 shown, a connecting thread 12 is arranged at a position near the lower end of the outer surface of the mounting block 11. The mounting block 11 is threadedly connected to the fixed cylinder 81 through the connecting thread 12. Anti-slip lines 13 are opened at a position near the upper end of the outer surface of the mounting block 11. When in use, it is convenient to fixedly install the mounting block 11 and the fixed cylinder 81 together.

[0034] In this embodiment, as Figure 4 and 5 shown, an installation hole 14 is formed inside the installation block 11, and the installation rod 91 is slidably inserted inside the installation hole 14, and the outer diameter dimension of the installation rod 91 is adapted to the inner diameter dimension of the installation hole 14. When in use, it provides necessary conditions for the installation rod 91 to be inserted into the installation hole 14, that is, the adaptive adjustment unit 9 can be installed inside the fixed cylinder 81 through the installation block 11.

[0035] In this embodiment, as Figure 2 shown, the socket cylinder 82 is slidably sleeved on the outer surface of the fixed cylinder 81, and the socket cylinder 82 is fixedly connected to the fixed cylinder 81 through a shock-absorbing spring 83. When in use, the elastic state of the shock-absorbing spring 83 provides appropriate stiffness or damping for the main structure of the damping shock-absorbing unit 8 to meet the requirements in normal applications.

[0036] In this embodiment, as Figure 1 and 2 shown, the fixed cylinder 81 is fixedly connected to the front beam frame 2 through a lower connection seat 16, and the socket cylinder 82 is fixedly connected to the rear beam frame 3 through an upper connection seat 15. When in use, by setting the lower connection seat 16 and the upper connection seat 15, the damping shock-absorbing unit 8, the shock-absorbing connecting plate 4 and the front beam frame 2 are fixedly connected together and become an integral body.

[0037] In this embodiment, as Figure 1 shown, a handlebar shaft installation tube 7 is fixedly connected to the front end of the front beam frame 2, a seat shaft installation hole 5 is formed at the upper end of the main frame 1, and a pedal installation hole 6 is formed at a position near the lower end on the outer surface of the main frame 1. When in use, it provides necessary conditions for assembling the bicycle.

[0038] In this embodiment, as Figure 1 shown, the main frame 1, the front beam frame 2, the rear beam frame 3, the shock-absorbing connecting plate 4 and the handlebar shaft installation tube 7 are all made of carbon fiber material, and the outer surfaces of the main frame 1, the front beam frame 2, the rear beam frame 3, the shock-absorbing connecting plate 4 and the handlebar shaft installation tube 7 are all sprayed with anti-rust paint. When in use, the carbon fiber material, due to its light weight, high strength and excellent corrosion resistance, can improve the overall performance of the bicycle frame, including reducing weight, increasing rigidity and durability, while maintaining good elasticity and shock-absorbing performance, thereby enhancing the comfort and safety of riding. Spraying anti-rust paint helps to protect the bicycle frame and extend the service life of the vehicle.

[0039] Working principle: When using an adaptive suspension device for a bicycle frame according to the present application, the damping shock absorption unit 8 is arranged between the shock absorption connecting plate 4 and the front beam frame 2, and is connected to the rear beam frame 3 through the shock absorption connecting plate 4 to form a whole, so as to improve the overall shock absorption ability. The shock absorption is realized through the cooperation between the fixed cylinder 81, the socket cylinder 82, the connecting rod 84, the working piston 85 and the main oil storage tank 86. When the riding environment is poor or the rider's weight is too large, resulting in a large impact force on the frame, a high-pressure area will be formed at the position where the connecting through hole 88 contacts the main oil storage tank 86, so that the damping oil will push open the adaptive adjustment unit 9 and pass through the fixed piston 10 into the internal part of the auxiliary oil storage tank 87, reducing the shock absorption burden of the damping shock absorption unit 8, thereby further improving the shock absorption effect of the damping shock absorption unit 8. That is, the device can realize adaptive vibration adjustment according to the road conditions and the rider's weight, thus significantly improving the smoothness and comfort of riding.
