Description

Technical Field

[0001] This utility model relates to the field of snow bike technology, specifically to a snow bike. Background Technology

[0002] Snowboarding is similar to sailing and windsurfing, except one is done on the water and the other on snow. This sport is highly entertaining and exciting, with athletes frequently making high-flying jumps from high mountains, making it very thrilling. It demands a high level of skill from the skiers.

[0003] Traditional snow transportation such as skis or sleds lack riding functionality, while ordinary bicycles cannot travel stably on snow.

[0004] Most existing snow bikes use fixed skis, which have problems such as clumsy steering, poor terrain adaptability, and incompatibility with ski lifts. When skiers ride ski lifts, snow bikes are inconvenient to carry, causing inconvenience to skiers.

[0005] To address the aforementioned technical issues, a snow bike is urgently needed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a snow bicycle, including a frame, a front ski installed at the front end of the frame, two parallel rear skis installed at the rear end of the frame via a swing assembly, an adjustable U-shaped bracket installed at the front end of the frame, a limit post and a compression spring rod provided on the front side of the frame, the two front sides of the U-shaped bracket being rotatably connected to the frame via a pivot, the limit post being located at the top of the U-shaped bracket, and the compression spring rod being located at the bottom of the U-shaped bracket to adjust the position of the U-shaped bracket;

[0007] When the U-shaped support is horizontal, it is easy to mount the U-shaped support on the cable car. When the U-shaped support is stored on both sides of the frame, it is convenient for snow biking.

[0008] Furthermore, the limiting posts are provided in two sets. One set of limiting posts is used to install on the left side of the frame, and the other set of limiting posts is used to install on the right side of the frame. Both sets of limiting posts are used to limit the top of the U-shaped bracket.

[0009] Furthermore, a rectangular groove is provided at the bottom end of the limiting post to facilitate its fit with the top surface of the U-shaped bracket.

[0010] Furthermore, the compression spring rod includes a button, a spring, and a housing. The housing is sleeved on the outer peripheral surface of the button and the spring. An extension post is provided at the bottom end of the button. The spring is sleeved on the outer peripheral surface of the extension post. The bottom end of the spring is fixedly connected to the bottom end of the housing.

[0011] The advantages of the utility model compared to the prior art are:

[0012] This utility model combines multiple structures such as a frame, front ski, rear ski, U-shaped bracket, limiting post, and compression spring rod to provide a snow bike with an adjustable U-shaped bracket position. Through the structure of the aforementioned limiting post and compression spring rod, the U-shaped bracket can be adjusted to a horizontal position, thereby enabling the U-shaped bracket to be mounted on a cable car, making it convenient and practical for skiers to carry their snow bikes while riding the cable car.

[0013] This invention, through the structural design of limiting posts and compression spring rods, allows the position of the U-shaped bracket to be adjusted and stored on both sides of the snow bike frame, preventing the U-shaped bracket from being deployed and affecting the skiing process, thus ensuring the safety of skiers during skiing.

[0014] This invention adds a rocker assembly to the rear of the snow bike, enabling automatic movement for the skier while reducing torsional stress on the lower limbs and joints. This invention also adds a shock-absorbing structure to the front fork support, improving the snow bike's shock absorption performance during use.

[0015] This invention achieves a movable connection between the swaying component and the frame via a rotating connector. This structure allows skiers to balance more movements during skiing and adapt to more snowy conditions. A shock-absorbing structure is added to the rotating connector, which enhances the snow bike's shock absorption performance and increases comfort during skiing. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] The present invention will be described in detail with reference to the accompanying drawings.

[0027] In a specific implementation, this utility model provides a snow bike, including a frame 1. A front ski 2 is installed at the front end of the frame 1, and two parallel rear skis 3 are installed at the rear end of the frame 1 via a swing assembly. An adjustable U-shaped bracket 4 is installed at the front end of the frame 1. A limit post 5 and a compression spring rod 6 are provided on the side of the front end of the frame 1. The two sides of the front end of the U-shaped bracket 4 are rotatably connected to the frame 1 via a pivot. The limit post 5 is located at the top of the U-shaped bracket 4, and the compression spring rod 6 is used to adjust the position of the U-shaped bracket 4.

[0028] When the U-shaped support 4 is in a horizontal position, it is convenient to mount the U-shaped support 4 on the cable car. When the U-shaped support 4 is stored on both sides of the frame 1, it is convenient for snow bikes to be used for skiing.

[0029] Example:

[0030] When used by skiers, this utility model allows the spring rod 6 to be pressed inwards, and after pressing, the U-shaped bracket 4 can be lowered and stored on both sides of the frame 1. The above structure can prevent the U-shaped bracket 4 from hitting the skier during use, thus ensuring the safety of the skier during skiing.

[0031] When skiers need to carry their snow bikes while riding the cable car, they can press button 6-1 in the spring rod 6 inward. Button 6-1 compresses spring 6-2 inward, causing it to retract into the outer casing 6-3. This rotates the U-shaped bracket 4 upward so that its top end fits against the bottom end of the limiting post 5. Releasing button 6-1 causes it to spring back to its initial position under the action of spring 6-2, limiting the U-shaped bracket 4 between the limiting post 5 and the spring rod 6. This structure allows the U-shaped bracket 4 to be adjusted to a horizontal position, making it easier to mount the U-shaped bracket 4 on the cable car and providing convenience for skiers to carry their snow bikes while riding the cable car.

[0032] The U-shaped bracket of the snow bike in this invention can be adjusted according to the usage scenario, which is highly flexible and convenient to use.

[0033] To facilitate the positioning of the U-shaped bracket, two sets of limiting posts 5 are provided. One set of limiting posts is installed on the left side of the frame 1, and the other set is installed on the right side of the frame 1. Both sets of limiting posts 5 are used to limit the top of the U-shaped bracket 4.

[0034] In order to make the limiting post fit the U-shaped bracket, the bottom end of the limiting post 5 is provided with a rectangular groove 7 so as to fit with the top surface of the U-shaped bracket 4.

[0035] To adjust the spring rod, the spring rod 6 includes a button 6-1, a spring 6-2, and a housing 6-3. The housing 6-3 is sleeved on the outer peripheral surface of the button 6-1 and the spring 6-2. An extension post 6-3 is provided at the bottom end of the button 6-1. The spring 6-2 is sleeved on the outer peripheral surface of the extension post 6-3. The bottom end of the spring 6-2 is fixedly connected to the bottom end of the housing 6-3.

[0036] To improve the flexibility of the snow bike during use, the sway assembly includes a first curved link 7, a second curved link 8, and a third curved link 9. The two ends of the first curved link 7 and the second curved link 8 are rotatably connected to the front end of the rear ski 3, and the first curved link 7 is positioned above the second curved link 8. The two ends of the third curved link 9 are rotatably connected to the rear end of the rear ski 3. The sway assembly is movably connected to the frame 1 through a rotating connector 13. One end of the rotating connector 13 is installed on the first curved link 7 and the second curved link 8 with screws, and the other end is rotatably connected to the frame 1 through a pivot. A shock absorber 14 is provided on the rear side of the rotating connector 13.

[0037] This invention achieves a movable connection between the swing component and the frame through a rotating connector. This structure enables skiers to balance more movements and adapt to more snowy scenarios during skiing.

[0038] To improve the shock absorption performance of the snow bike, a front fork bracket 10 is provided at the front end of the frame 1, and a shock absorber is provided at the connection between the front fork bracket 10 and the front ski 2. This invention improves the shock absorption performance of the snow bike by adding a shock absorber.

[0039] To increase the stability of the snowmobile during use, the surface of the rear ski 3 is provided with an anti-slip texture component 11. The anti-slip texture component 11 includes trapezoidal anti-slip texture 11-1 and U-shaped anti-slip texture 11-2. The trapezoidal anti-slip texture 11-1 is located in the middle of the U-shaped anti-slip texture 11-2. The trapezoidal anti-slip texture 11-1 and the U-shaped anti-slip texture 11-2 are inclined and their height increases sequentially from rear to front. This structural design of the anti-slip texture component increases the stability of the skier when stepping on the rear ski 3, enhancing the skier's safety and preventing slips during skiing.

[0040] As a further explanation of this utility model, the anti-slip texture component 11 on the surface of the rear ski 3 is evenly distributed.

[0041] As a further explanation of this utility model, the front end of the frame 1 is provided with a handle 12.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
