Technical Field

[0001] The utility model relates to the field of bicycle components, in particular to a novel double front fork structure of a bicycle. Background Art

[0002] The front fork of a bicycle is generally a single fork, on which the shock absorber and the brake device are arranged. Since the front fork of a bicycle needs to be adapted and adjusted according to the overall size of the bicycle, the actual available space on the front fork is small, and the shock absorbing device can only be of a limited length, and there are certain limitations in terms of increasing functions. The existing double front fork generally has two front forks fixedly connected to each other at the bottom ends, and shares a shock absorbing device at the top. Compared with the single front fork technology, it has no other advantages except that the structure is more solid.

[0003] In addition, since the bottom ends of traditional double front forks need to be fixedly connected to each other, there is not enough space left for installing disc brake components, and only traditional V-brake type brake components can be used. Since disc brakes can provide a more powerful and stable braking effect than V-brakes, the inability of traditional double front forks to install disc brake components will limit the additional configuration needs of many bicycle users.

[0004] Therefore, the existing bicycle front fork structure needs to be further improved. Utility Model Content

[0005] In view of the above-mentioned prior art, the technology to be realized by the utility model is: changing the double front fork structure in the traditional technology, having more space to set a larger shock absorber to increase the shock absorption effect, and increasing the space for installing functional accessories. A disc brake installation position is reserved so that the double front fork structure can be equipped with a disc brake.

[0006] In order to achieve the above purpose, the utility model adopts the following scheme:

[0007] A novel double front fork structure of a bicycle comprises a front fork installed on a head tube, the front fork comprises a main front fork and a secondary front fork, a suspended fixed structure is arranged between the main front fork and the secondary front fork, a shock absorber is arranged on the secondary front fork and connected to the suspended fixed structure, and a disc brake connection structure is arranged on the secondary front fork.

[0008] Furthermore, the auxiliary front fork in the utility model is arranged on the front side of the main front fork.

[0009] Furthermore, the auxiliary front fork in the utility model is provided with a plurality of piers at the top, an end plate is provided at the bottom, and an axle fork connected to the front wheel of the bicycle is provided at the bottom of the end plate.

[0010] Furthermore, the shock absorber in the utility model is a spring shock absorber and the lower end is connected to the pier column.

[0011] Furthermore, the disc brake connection structure in the utility model is a disc brake support plate connected to the rear side of the end plate, and the disc brake of the bicycle is installed on the disc brake support plate.

[0012] Furthermore, the suspended fixing structure in the utility model includes a pressure plate arranged on the top of the shock absorber, the pressure plate is installed on the elastic member of the shock absorber, and a sleeve plate fixedly sleeved on the upper side of the bicycle head pipe is arranged on the rear side of the pressure plate.

[0013] Furthermore, the suspended fixing structure in the utility model also includes a hinged rod hinged between the bottom of the main front fork and the bottom of the auxiliary front fork.

[0014] Furthermore, the auxiliary front fork in the utility model is provided with functional holes for installing functional components.

[0015] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0016] The utility model provides a main front fork and a secondary front fork, and through the connection between the shock absorber and the suspended fixed structure, the secondary front fork can have a shock absorbing function, and the shock absorber installed on the secondary front fork can be adapted to a wider range of sizes, with more space for installing functional accessories.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0022] like Figures 1 to 4The novel double front fork structure of a bicycle comprises a front fork installed on a head tube, the front fork comprises a main front fork 1 and a secondary front fork 2, a suspended fixed structure 3 is provided between the main front fork 1 and the secondary front fork 2, a shock absorber 4 is provided on the secondary front fork 2 and connected to the suspended fixed structure 3, and a disc brake connection structure 5 is provided on the secondary front fork 2. The front fork as a whole is installed on the head tube of the bicycle for fixed point rotation, and is divided into a main front fork and a secondary front fork and connected through the connection of the suspended fixed structure and the shock absorber, so that the secondary front fork as a whole can move up and down and has a shock absorbing function. The main front fork and the secondary front fork reserve space for installing the disc brake connection structure, so that a disc brake type brake component can be installed on the disc brake connection structure.

[0023] The auxiliary front fork 2 described in the utility model is arranged on the front side of the main front fork 1. It is arranged on the front side of the main front fork and does not interfere with other components. The auxiliary front fork is used to install the front wheel and the shock absorber as a whole.

[0024] The auxiliary front fork 2 described in the utility model is provided with a plurality of piers 21 at the top, an end plate 22 at the bottom, and an axle fork 23 connected to the front wheel of the bicycle at the bottom of the end plate 22. The traditional double front fork structure is that the main front fork and the auxiliary front fork are fixedly connected to each other, a rod is provided at the top of both to be rotatably connected to the head tube, and the bottom is used to fix the front wheel of the bicycle together. This technology is different from the prior art, the piers can be connected to the shock absorber, the front wheel of the bicycle is installed on the axle fork, and both are set on the auxiliary front fork, and the main front fork is used to connect with the auxiliary front fork and plug into the head tube.

[0025] The shock absorber 4 described in the utility model is a spring shock absorber 4 and the lower end is connected to the pier 21. In this technical solution, a spring shock absorber is selected as the shock absorbing facility, the lower end is connected to the pier, and the upper end is connected to the main front fork through a suspended fixed structure. According to actual conditions, other shock absorbing facilities that can be used for shock absorption can be used, such as a hydraulic shock absorbing cylinder.

[0026] The disc brake connection structure 5 described in the utility model is a disc brake support plate connected to the rear side of the end plate 22, and the disc brake of the bicycle is installed on the disc brake support plate. The end plate is set at the bottom of the auxiliary front fork. Since the main front fork does not have an end plate, the end plate is protruding separately, and the space at the rear side can be used to set the disc brake support plate, which is used as a reserved installation position for the disc brake, so it can be used to install a brake assembly of the disc brake type. In the prior art, the bottom of the auxiliary front fork and the main front fork are fixedly connected, and there is no reserved disc brake installation position, so only a V-brake type brake assembly can be installed.

[0027] The suspended fixed structure 3 described in the utility model includes a pressure plate 31 arranged on the top of the shock absorber 4, and the pressure plate 31 is installed on the elastic member of the shock absorber 4. A sleeve plate 32 fixedly sleeved on the upper side of the bicycle head tube is arranged on the rear side of the pressure plate 31. The bottom of the shock absorber is a pier column, the top is a pressure plate, and the pressure plate is installed on the elastic member. In this technology, since the shock absorber is a spring shock absorber, and the spring shock absorber is an existing common technology, the elastic member is a spring, that is, the pressure plate is connected to the spring. When the front wheel is stressed, the spring in the shock absorber shrinks, and the pressure plate presses down on the shock absorber to achieve a shock absorption effect. The sleeve plate is fixedly connected to the pressure plate and is used to be fixedly sleeved on the head tube and rotated at a fixed point. In this technology, since the sleeve plate needs to be connected to the head tube, when the size of the shock absorber changes, sleeve plates of different shapes need to be used to achieve connection with the head tube. The sleeve plate in this technology is a slope shape, and a variety of different sleeve plates can be set according to the national standard size and used according to the additional requirements.

[0028] The suspended fixed structure 3 in the utility model also includes a hinged rod 33 hinged between the bottom of the main front fork 1 and the bottom of the auxiliary front fork 2. The hinged rod is used to connect the bottom of the main front fork and the bottom of the auxiliary front fork. When the auxiliary front fork is subjected to force during driving, the up and down movement of the bottom can be achieved by the hinged rod. In the prior art, the bottom of the auxiliary front fork and the main front fork are fixedly connected, so the performance in terms of shock absorption effect is poor.

[0029] The auxiliary front fork 2 of the present invention is provided with a functional hole 6 for installing functional components. The functional hole can be used to connect functional components such as headlights and storage frames.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
