DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3The vehicle pedal automatic adjustment mechanical leg device shown includes a plate body 3 and an arc-shaped plate head 1 arranged at the front end of the plate body 3, an arc-shaped plate tail 8 is arranged at the rear end of the plate body 3, a metal bracket plate A4 is arranged at the top of the left end of the middle section of the plate body 3, and a metal bracket plate B5 is arranged at the top of the right end of the middle section of the plate body 3. Reinforcement connecting rods are connected between the front and rear ends of the metal bracket plates A4 and B5, and the reinforcement connecting rods are fixedly connected to the metal bracket plates A4 and B5 by welding. A U-shaped connecting frame 6 is inserted in the middle section between the metal bracket plates A4 and B5, and the U-shaped opening of the U-shaped connecting frame 6 faces downward. The U-shaped connecting frame 6 is fixedly connected to the metal bracket plates A4 and B5 by multiple fixing bolts 7, and a triangular support plate 13 is welded to the top of the top frame plate 11. A metal mounting tube 12 is fixed at the end. When installing and using the vehicle pedal automatic adjustment mechanical leg device, firstly, the metal mounting tube 12 on the triangular support plate 13 needs to be fixedly connected to the front axle of the ski vehicle through the mounting shaft, and then the ski pedal composed of the arc-shaped board head 1, the board body 3 and the arc-shaped board tail 8 needs to be placed on the lower side of the U-shaped connecting frame 6, and then the lower end of the U-shaped connecting frame 6 needs to be inserted between the metal bracket plate A4 and the metal bracket plate B5 at the top of the board body 3, and then the U-shaped connecting frame 6 needs to be fixedly connected with the metal bracket plate A4 and the metal bracket plate B5 using the fixing bolts 7, and then the automatic adjustment hydraulic machine 10 at the bottom of the top frame plate 11 needs to be connected to the hydraulic cylinder on the ski vehicle through the oil pipe, so that the hydraulic cylinder of the ski vehicle can supply pressure and relieve pressure to the automatic adjustment hydraulic machine 10 through the oil pipe.

[0022] like Figure 1 and Figure 2As shown, an automatic adjusting hydraulic device 10 is arranged at the top center of the U-shaped connecting frame 6, and a top frame plate 11 is arranged at the top of the automatic adjusting hydraulic device 10. The automatic adjusting hydraulic device 10 is connected to the hydraulic cylinder of the ski vehicle through an oil pipe, and the automatic adjusting hydraulic device 10 can drive the top frame plate 11 to move up and down. Lifting guide holes 9 are arranged inside the front and rear sides of the top center of the U-shaped connecting frame 6, and lifting guide rods 14 are inserted in the two lifting guide holes 9. The top of the lifting guide rod 14 is fixedly connected to the top frame plate 11 through a flange and screws. The lifting guide rod 14 can move up and down in the lifting guide hole 9. A stopper is also arranged at the bottom of the lifting guide rod 14. The stopper is located inside the U-shaped connecting frame 6U, and the diameter of the stopper is larger than the diameter of the lifting guide hole 9. When the ski vehicle is galloping on the snow through the snow tracks and ski pedals, because the ground conditions of the snow are diverse, When driving on different road conditions, the ski vehicle will change the ski height of the ski pedal through the automatic adjusting hydraulic device 10, so that the ski vehicle can flexibly adapt to different snow road conditions. When the automatic adjusting hydraulic device 10 is working, the hydraulic cylinder on the ski vehicle will pressurize and relieve the pressure of the automatic adjusting hydraulic device 10 through the oil pipe. The pressurization will cause the automatic adjusting hydraulic device 10 to push the hydraulic shaft outward. Because the bottom end of the hydraulic shaft is fixedly connected to the U-shaped connecting frame 6, the U-shaped connecting frame 6 and the ski pedal will be pushed downward when the hydraulic shaft is pushed outward, so that the ski pedal is raised. When the internal pressure of the automatic adjusting hydraulic device 10 is relieved, the hydraulic shaft will be reset, which will reduce the height between the body of the ski vehicle and the ski pedal. By flexibly changing the height between the ski pedal and the body of the ski vehicle, the ski vehicle can adapt to a variety of different snow road conditions.

[0023] like Figure 1 and Figure 3 As shown, the top outer wall of the connection between the arc-shaped plate head 1 and the plate body 3 is connected to the plate head reinforcement device 2, and the plate head reinforcement device 2 includes an arc-shaped fixing plate 15, a reinforcement support screw A16, an internal thread support tube 17, a reinforcement support screw B18 and a triangular support frame 19. The arc-shaped fixing plate 15 is welded to the top outer wall of the arc-shaped plate head 1, and the triangular support frame 19 is fixed to the top outer wall of the front end of the plate body 3. The top rear end outer wall of the arc-shaped fixing plate 15 is welded with a reinforcement support screw A16, and the top front end outer wall of the triangular support frame 19 is welded with a reinforcement support screw B18. The reinforcement support screw A16 and the reinforcement support screw The external thread of rod B18 is sleeved with an internal thread support tube 17, and the external cross-sectional shape of the internal thread support tube 17 is a regular hexagon. The internal thread support tube 17 can rotate clockwise to push the reinforcing support screw A16 forward and the reinforcing support screw B18 backward through the pushing action of the thread. The triangular support frame 19 is composed of an L-shaped metal plate and two triangular support plates. The bottom end of the L-shaped metal plate is fixed to the outer wall of the top end of the plate body 3 by welding, and the rear end of the reinforcing support screw B18 is fixedly connected to the L-shaped metal plate by welding. The two triangular support plates are respectively welded to the L-shaped inner walls at the left and right ends of the L-shaped metal plate.

[0024] like Figure 1 and Figure 3 As shown, because the ski vehicle needs to maintain balance and control the sliding direction through the ski pedal at the bottom of the front end when galloping on the snow, once the ski vehicle encounters an obstacle, the ski pedal will collide with the obstacle. Because the arc-shaped board head 1 at the front end of the ski pedal adopts an arc-shaped design with the front end tilted upward to allow the ski vehicle to slide flexibly, when the arc-shaped board head 1 hits the obstacle, a strong impact force will directly act on the connection between the arc-shaped board head 1 and the board body 3, and because the two ends of the internal thread support tube 17 are respectively threadedly sleeved on the reinforcing support The outer part of the screw rod A16 and the reinforcing support screw rod B18, and the front end of the reinforcing support screw rod A16 is fixedly connected to the arc-shaped plate head 1 through the arc-shaped fixing plate 15, and the rear end of the reinforcing support screw rod B18 is fixedly connected to the plate body 3 through the triangular support frame 19, so the internal thread support tube 17 and the reinforcing support screw rod A16 and the reinforcing support screw rod B18 connected together will play a supporting and reinforcing role between the arc-shaped plate head 1 and the plate body 3. When the arc-shaped plate head 1 is hit, the internal thread support tube 17 and the reinforcing support screw rod A16 and the reinforcing support screw rod B18 connected as a whole 16 and the reinforcing support screw B18 will help the curved board head 1 to resist the impact force generated during the collision, so as to prevent the impact force from acting on the connection between the curved board head 1 and the board body 3 and causing the connection between the two to break. In addition, because the rear end of the reinforcing support screw B18 is fixedly connected to the triangular support frame 19, and the bottom end of the triangular support frame 19 is fixedly connected to the board body 3, when the curved board head 1 hits an obstacle, the impact force will be transmitted to the triangular support frame 19, and the triangular support frame 19 will resist the strong impact force through its own triangular reinforcement structure. Combined with the internal threaded support tube 17, the reinforcing support screw A16 and the reinforcing support screw B18 connected as a whole, it can ensure that the arc plate head 1 does not suffer significant deformation and damage when the arc plate head 1 hits an obstacle. When the arc plate head 1 is deformed, it is only necessary to rotate the internal threaded support tube 17 clockwise or counterclockwise with a movable wrench. The internal threaded support tube 17 will push the reinforcing support screw A16 and the reinforcing support screw B18 outward, thereby pushing the arc plate head 1 forward, so that the originally deformed arc plate head 1 can be quickly restored.
