The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of the present application is:

[0021] See also Figure 1-Figure 3 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model; Figure 2 It is a structural schematic diagram of a suspension assembly of the first embodiment of the utility model; Figure 3 It is a cross-sectional view of the suspension assembly of the first embodiment of the utility model.

[0022] The utility model provides a snowmobile with a suspended snowboard, comprising a frame 101 and a suspension mechanism, wherein the suspension mechanism comprises a suspension frame 102, two suspension boxes 103, four suspension components and two snowboards 104, wherein the suspension component comprises a connecting frame 105, a connecting shaft 106, a suspension shaft 107 and a strong spring 108, three auxiliary shafts 110, a protective tube 111, a driven shaft 112, a driven wheel 113, a first reinforcing rib 114 and a second reinforcing rib 115. The above-mentioned solution solves the problem that the above prior art only has a single snowboard, which may roll over during skiing, thereby threatening the safety of the driver.

[0023] According to the present specific embodiment, the suspension rack 102 is fixedly connected to the bottom of the frame 101, the two suspension boxes 103 are respectively fixedly connected to the two sides of the bottom of the suspension rack 102, each of the snowboards 104 is located below each of the suspension boxes 103, each of the two suspension components are located above each of the snowboards 104, and one is located at the front end and the other is located at the rear end, the connecting rack 105 is fixedly connected to the top of the snowboards 104, the connecting shaft 106 is fixedly connected to the top of the connecting rack 105, the suspension shaft 107 is fixedly connected to the top of the connecting shaft 106 and passes through the bottom of the suspension box 103, and each of the suspension shafts 107 is provided with a limit block 109 on the top, the limit block 109 is located in the suspension box 103, the strong spring 108 is sleeved on the outside of the suspension shaft 107 and is located between the suspension box 103 and the connecting shaft 106. During the movement of the sled, if the sled tends to roll over, the vehicle The frame 101 is tilted, so that the suspension frame 102 and the suspension box 103 on this side are pressed down, and the suspension box 103 approaches the connecting shaft 106, squeezing the strong spring 108, and the skis 104 and the connecting frame 105 support the side of the frame 101 through the strong spring 108 and the suspension frame 102. After the rollover pressure is reduced, the frame 101 and the suspension box 103 are reset under the elastic force of the strong spring 108, and the frame 101 is supported by the support on both sides. Stop rolling over and reset; if the ski board 104 slides over an uneven road surface, the ski board 104 is lifted up by the protrusions on the road surface, and the connecting shaft 106 and the suspension shaft 107 are driven upward by the connecting frame 102 to squeeze the spring with the suspension box 103, thereby shortening the distance between the ski board 104 and the frame 101 to prevent the sled from being lifted up by the protrusions on the road surface and causing rolling over; at the same time, under the restriction of the limit block 109, the suspension shaft 106 cannot move out of the suspension box 103.

[0024] Among them, the three auxiliary shafts 110 are fixedly connected in the suspension box 103, and pass through the limit block 109, and are slidably connected to the limit block 109. The protective tube 111 is fixedly connected to the bottom of the suspension box 103 and covers the strong spring 108. When the snowboard 104 slides over the road surface bump, the snowboard is lifted up, the connecting shaft 106 rises, and squeezes the strong spring 108 with the suspension box 103, and the suspension shaft 107 drives the limit block 109 to move into the suspension box 103; at the same time, under the restriction of the limit block 109, The suspension shaft 107 moves along the three auxiliary shafts 110, making the movement of the suspension shaft 107 more stable; if the sled itself tends to roll over, the suspension frame 102 tilts along with the frame 101, and the suspension box 103 in the direction of the sled's rollover tendency is pressed down along the suspension shaft 106, shortening the distance between the ski board 104 and the frame 101 to prevent the sled from being pushed by a bump on the road surface and causing it to roll over; at the same time, the three auxiliary shafts 110 move downward along the through holes on the limit block with the suspension box 103, making the downward pressure of the suspension box 103 more stable.

[0025] Secondly, the ski board 104 is also provided with a driven groove, the driven shaft 112 is fixedly connected to the connecting frame 105, and the driven wheel 113 is sleeved on the surface of the driven shaft 112 and is located in the driven groove. When the sled moves, the driven wheel 113 contacts the snow and rotates, making the movement of the sled more sensitive; at the same time, if the sled needs to be driven into the garage, the four driven wheels 113 contact the ground instead of the ski board 104, which can effectively prevent the ski board 104 from being worn, thereby extending the service life of the sled.

[0026] At the same time, the first reinforcing rib 114 is fixedly connected to the ski board 104 and the connecting frame 105 and is located on one side of the connecting frame 105. The second reinforcing rib 115 is fixedly connected to the ski board 104 and the connecting frame 105 and is located on a side of the connecting frame 105 away from the first reinforcing rib 114. When the ski board 104 is used, the overall movement intensity of the sled vehicle is relatively high. The first reinforcing rib 114 and the second reinforcing rib 115 can stabilize the connection between the ski board 104 and the connecting frame 105 to prevent the ski board 104 from separating from the connecting frame 105.

[0027] During the movement of the sled, if the sled shows a tendency to roll over, the frame 101 tilts, so that the suspension frame 102 and the suspension box 103 on that side are pressed down, and the suspension box 103 approaches the connecting shaft 106, squeezing the strong spring 108, shortening the distance between the ski board 104 and the frame 101, so as to prevent the sled from being pushed up by the bumps on the road surface and causing the sled to roll over; at the same time, the three auxiliary shafts 110 move downward along the perforations on the limit block 109 with the suspension box 103, so that the downward pressure of the suspension box 103 is more stable; if the ski board 104 slides over an uneven road surface, the ski board 104 is pushed up by the bumps on the road surface, and the ski board 104 is pushed up by the bumps on the road surface. The connecting frame 105 drives the connecting shaft 106 and the suspension shaft 107 to move upward, and compresses the spring with the suspension box 103 to shorten the distance between the ski board 104 and the frame 101 to prevent the sled from being pushed by the bumps on the road surface and causing rollover. The ski board 104 and the connecting frame 105 support the side of the frame 101 through the strong spring 108 and the suspension frame 102. After the rollover pressure is reduced, the frame 101 is reset under the elastic force of the strong spring 108, and the suspension frame 102 is reset with the frame 101. The suspension box rises, driving the three auxiliary shafts 110 to rise along the through holes on the limit block 109 until The limit block 109 is pressed against the suspension box 103, and the reset of the sled is completed; when the sled returns to the flat road, the ski board 104 is reset under the elastic force of the strong spring 108, and the connecting shaft 106 is pushed downward by the strong spring 108, driving the connecting frame 105, the ski board 104 and the suspension shaft 107 to move downward, and the suspension shaft 107 drives the limit block 109 to move downward along the three auxiliary shafts 110 until the limit block 109 is pressed against the suspension box 103, and the reset of the sled is completed; at the same time, under the restriction of the limit block 109, the suspension shaft 106 cannot move out of the suspension box 10 3. Prevent the parts of the sled from falling off; when the sled is in use, the protective tube 111 always covers the powerful spring 109, which can effectively prevent debris from getting stuck in the gap of the powerful spring 109 and affecting the operation of the powerful spring 109; because the overall movement intensity of the sled is relatively high when the ski 104 is in use, the first reinforcing rib 114 and the second reinforcing rib 115 can stabilize the connection between the ski 104 and the connecting frame 105, preventing the ski 104 from separating from the connecting frame 105; when the sled is moving, the driven wheel 113 contacts the snow and rotates, making the movement of the sled more sensitive;At the same time, if the sled needs to be driven into the garage, the four driven wheels 113 contact the ground instead of the skis 104, which can effectively prevent the skis 104 from being worn, thereby extending the service life of the sled. The frame 101 stops rolling over and resets through the support on both sides, avoiding the problem that the existing technology only has a single ski, which may roll over during skiing and threaten the safety of the driver, thereby achieving the effect of protecting the safety of the driver. ;

[0028] The second embodiment of the present application is:

[0029] See also Figure 4-Figure 5 ,in Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the utility model; Figure 5 It is a structural schematic diagram of the shielding mechanism of the second embodiment of the utility model.

[0030] On the basis of the first embodiment, the snowmobile with a suspended snowboard in this embodiment further includes a shielding mechanism, which includes an umbrella frame 201 , a front umbrella board 202 and a rear umbrella board 203 .

[0031] Among them, the umbrella frame 201 is fixedly connected to the top of the frame 101, the front umbrella board 202 is fixedly connected to the top of the umbrella frame 201, and the rear umbrella board 203 is fixedly connected to the rear of the top of the umbrella frame 201. When the sled is in use, if the sunlight is too strong, the sunlight will be blocked by the front umbrella board 202 and the rear umbrella board 203; if it is snowing, snowflakes will fall on the front umbrella board 202 and the rear umbrella board 203, and then slide down along the two sides of the front umbrella board 202 and the rear umbrella board 203; the airflow caused by the movement of the sled will flow through the gap between the front umbrella board 202 and the rear umbrella board 203, and will not affect the driving of the sled, thereby achieving the effect of shielding the driver from rain, snow and sunlight in different weathers.
