[0001] The utility model relates to the technical field of bicycle accessories, in particular to a bicycle swing-rod type shock-absorbing front fork assembly. Background Art

[0002] Patent publication number CN204223111 U discloses a bicycle swing-bar suspension front fork assembly, comprising a front fork stem and front fork legs. The top of one short end of the Y-shaped swing bar is hinged to the lower end of the front leg. The top of the other short end of the Y-shaped swing bar is provided with a locking nut hinged to the front wheel hub axle. The long end of the Y-shaped swing bar is hinged to the shock absorber. The upper end of the front fork leg is provided with a fixed seat hinged to the other end of the shock absorber. The swing bar and shock absorber are symmetrically mounted on either side of the front wheel hub axle, either unilaterally or bilaterally. This utility model effectively achieves cushioning and shock absorption through compression and shock absorption through a simple swing bar structure. It is low-cost, lightweight, and suitable for riding on both urban and rural roads.

[0003] The inventors have found that although the above-mentioned components are low-cost and suitable for riding on urban and rural roads, their shock absorption effect is not good. Therefore, we propose a bicycle swing arm type suspension front fork assembly. Utility Model Content

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the utility model provides a bicycle swing arm type suspension front fork assembly, which has the following beneficial effects:

[0019] With the bicycle rocker-type suspension front fork assembly, when the front fork is subjected to vibration or impact, the oil spring shock absorber on the front fork consumes most of the vibration or impact force, while the remaining vibration or impact force is transmitted to the spring damping rod via the supporting frame, the oblique ribs, the connecting seat and the lower supporting seat. At this time, the spring damping rod absorbs the energy of the vibration or impact force of the remaining part and reduces shock. At the same time, the spring damping rod plays a role in increasing the shock absorbing clamping force, so as to improve the shock absorbing and shock absorbing effect, thereby effectively reducing the vibration suffered by the front fork and achieving a good shock absorbing effect.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1-3 , provides a bicycle swing arm type suspension front fork assembly, comprising: a front fork stem 1;

[0026] The oil spring shock absorber 2 is provided on the shoulder box of the front fork stem 1. The oil spring shock absorber 2 is used for shock absorption and vibration reduction. The oil spring shock absorber 2 cushions and absorbs the instantaneous movement of the bicycle by the oil in the shock absorber between the spring and the shock absorber, while adjusting the shock absorption force to achieve the shock absorption effect.

[0027] The outer fork leg 4 is provided on the outer surface of the oil spring shock absorber 2;

[0028] Auxiliary shock absorber 3, which is provided on the shoulder box of the front fork seat tube 1 and is fixedly connected to the outer fork leg 4. The auxiliary shock absorber 3 is used for shock absorption and vibration prevention;

[0029] The reinforcement beam 5 is provided on the outer fork leg 4 .

[0030] Reference Figure 1 and Figure 2 The auxiliary shock absorber 3 includes a spring damping rod 31, one end of the spring damping rod 31 is fixedly mounted with an upper bearing seat 32, and the side of the upper bearing seat 32 away from the spring damping rod 31 is fixedly connected to the shoulder box of the front fork stem 1;

[0031] The other end of the spring damping rod 31 is fixedly mounted with a lower bearing seat 33, and a connecting bearing structure is provided on the side of the lower bearing seat 33 away from the spring damping rod 31. In use, when the front fork is subjected to vibration or impact, the oil spring shock absorber 2 on the front fork consumes most of the vibration or impact force, and the other part of the vibration or impact force is transmitted to the spring damping rod 31 through the connecting bearing structure. At this time, the spring damping rod 31 absorbs and reduces the energy of the vibration or impact force of the other part. At the same time, the spring damping rod 31 plays a role in increasing the shock absorbing clamping force to improve the shock absorbing and shock absorbing effect, thereby effectively reducing the vibration of the front fork and having a good shock absorbing effect.

[0032] Reference Figure 3 The connecting bearing structure includes a connecting seat 34, one side of the connecting seat 34 is fixedly connected to the side of the upper bearing seat 32 away from the spring damping rod 31, and a bearing frame 35 is fixedly installed on the other side of the connecting seat 34, and one end of the bearing frame 35 away from the connecting seat 34 is fixedly connected to the outer fork leg 4, and an oblique rib 36 is fixedly installed on the bearing frame 35, and one end of the oblique rib 36 away from the bearing frame 35 is fixedly connected to the connecting seat 34. In application, when the front fork is subjected to vibration or impact, part of the vibration or impact force is transmitted to the spring damping rod 31 through the bearing frame 35, the oblique rib 36, the connecting seat 34 and the lower bearing seat 33, so as to facilitate the transmission of the vibration or impact to the spring damping rod 31, thereby facilitating shock absorption and vibration prevention.

[0033] The support frame 35 is A-shaped so as to transmit the vibration or impact force to the spring damping rod 31 .

[0034] The reinforcement beam 5 is arc-shaped to facilitate connection with the outer fork leg 4 .

[0035] During actual use, when the front fork is subjected to vibration or impact, the oil spring shock absorber 2 on the front fork consumes most of the vibration or impact force, while the remaining vibration or impact force is transmitted to the spring damping rod 31 through the supporting frame 35, the oblique rib 36, the connecting seat 34 and the lower supporting seat 33. At this time, the spring damping rod 31 absorbs and reduces the vibration or impact force of the remaining part. At the same time, the spring damping rod 31 plays a role in increasing the shock absorbing clamping force to improve the shock absorbing and shock absorbing effect, thereby effectively reducing the vibration of the front fork and achieving a good shock absorbing effect. The device can not only effectively reduce the vibration of the front fork, but also achieve a good shock absorbing effect.
