As shown in Fig. 1 and Fig. 2, the utility model universal vehicle 100 includes a chassis 1 and four wheels 2, each of which is provided with a wheel 2 on both sides of the chassis 1, and the two wheels 2 positioned at the front are on the same horizontal axis. , two wheels 2 that are positioned at the rear are on the same horizontal axis, and described wheel 2 can be existing common wheel 2, also can be spherical wheel, and the utility model adopts spherical wheel. Setting the wheel 2 as a spherical wheel makes it easier to turn the wheel 2 on the one hand, and on the other hand keeps the appearance of the wheel 2 unchanged before and after turning, so that the universal vehicle 100 is more beautiful.

As shown in Figures 3 and 4, the universal vehicle 100 also includes a wheel steering mechanism 3 and a drive motor 4, the wheel steering mechanism 3 is arranged between the chassis 1 and the wheels 2, and drives the Said wheel 2 rotates 180 degrees or above around the vertical steering axis 21. The wheel steering mechanism 3 includes a swing arm 31 , one end of the swing arm 31 is pivotally connected to the chassis 1 , and the other end of the swing arm 31 is connected to the wheel 2 . Specifically, the swing arm 31 has a bent structure with a bending angle of 90 degrees, thereby forming a horizontal section 31a and a vertical section 31b. The chassis 1 is provided with a pivot shaft 11, and one end of the horizontal section 31a is covered with Connected to the pivot shaft 11 of the chassis 1, the other end is fixedly connected to the vertical section 31b; the chassis 1 is provided with an arc-shaped guide groove 12, and the guide groove 12 is located at On the chassis 1 above the inner hemisphere, the angle corresponding to the circular arc where the guide groove 12 is located is equal to or greater than 180 degrees, which is 180 degrees in the utility model; the upper end of the vertical section 31b is sleeved on the guide groove 12 and slide along the guide groove 12, and the other end is connected to the rotating shaft 22 of the wheel 2.

Referring again to Fig. 3 and shown in Fig. 4, the drive motor 4 is fixed on the lower end of the vertical section 31b of the swing arm 31 and the output end of the drive motor 4 is connected with the rotating shaft 22 of the wheel 2, The driving motor 4 drives the wheel 2 to rotate around the rotating shaft 22 to realize the walking of the universal vehicle 100 . By setting the driving motor on the swing arm 31 and directly driving the wheels 2 for walking, the driving mechanism is simplified and the driving is simpler and more convenient. The drive motor 4 can also be arranged on the horizontal section 31a of the swing arm 31 and connected to the wheel 2 through a bevel gear.

Referring to Fig. 4 again, the wheel steering mechanism 3 also includes a gear 32 and a driving rack (not shown in the figure), and the gear 32 and the swing arm 31 are coaxially pivoted to the bottom of the chassis 1. The pivot shaft 11 is fixedly connected with the swing arm 31 . The driving rack meshes with the gear 32 . In addition, the utility model adopts the form that a drive rack drives a gear 32 independently. Of course, the two gears 32 corresponding to the front and rear wheels 2 on the same side of the chassis 1 can also use a drive together. rack, so as to simultaneously drive the front and rear two wheels 2 on the same side of the chassis 1 to turn. The utility model can also use the driving gear to drive the gear 32, and use one of the driving gears between the corresponding two gears 32 of the two front wheels 2 to simultaneously drive the two front wheels 2 to turn.

Based on the above, the walking principle of the utility model universal vehicle 100 is described in detail below, as follows:

As shown in Figure 5, when the universal vehicle 100 is required to walk forward and backward, the swing arm 31 positioned on the front and rear wheels 2 is in the middle of the guide groove 12, and the four rotating shafts 22 of the wheels 2 The direction is perpendicular to the front and rear directions of the chassis 1, and the four wheels 2 can rotate forwardly or reversely at this moment to realize longitudinal travel.

As shown in Figure 6, when the universal vehicle 100 is required to turn, the swing arm 31 positioned on the left front wheel 2 moves a certain angle along the front section of the guide groove 12, while the swing arm 31 positioned on the right front wheel 2 Move the same angle along the rear section of the guide groove 12. At this time, the two front wheels 2 swing to the left at a certain angle, and the two rear wheels 2 do not bend. At this time, the respective wheels 2 are driven forward by four drive motors 4. Rotate, can realize universal car 100 turns left driving. In like manner also can realize universal car 100 turns right driving.

As shown in Figure 7, when the universal vehicle 100 is required to travel laterally, the two swing arms 31 positioned on the left front wheel 2 and the left rear wheel 2 move to the front end along the front section of the guide groove 12, and are positioned on the right front wheel at the same time. 2 and the swing arm 31 on the right rear wheel 2 moves to the rearmost end along the rear section of the guide groove 12. At this time, the directions of the rotation axes 22 of the four wheels 2 are parallel to the front and rear directions of the chassis 1 At this time, the four wheels 2 can be rotated in the forward direction to realize the universal vehicle 100 to move laterally to the left. In the same way, lateral travel to the right can also be realized.

As shown in Figure 8, when the universal vehicle 100 is required to rotate clockwise around the center of the chassis 1, the swing arms 31 of the four wheels 2 move along the direction of the guide groove 12, so that the rotation shafts 22 of the respective wheels 2 The direction is along the diagonal direction of the wheel 2 where the wheel 2 is located. At this time, the left front and rear wheels and the right rear wheel rotate in the forward direction, and the right front wheel and the left rear wheel rotate in the opposite direction to realize the universal vehicle 100 around the center of the chassis 1. Turn clockwise in place. In the same way, counterclockwise rotation can also be realized.

As shown in Figure 9, when the universal vehicle 100 is required to rotate counterclockwise around the central axis 21 of the right rear wheel, the rotation axis 22 of each other wheel 2 is swung to the direction perpendicular to the line between the wheelbase between the right rear wheel and the right rear wheel. , Then, the right front wheel rotates in the forward direction, the left front wheel rotates in the reverse direction, the left rear wheel rotates in the opposite direction, and the right rear wheel does not move, so that the universal vehicle 100 can be realized to rotate around the central axis 21 of the right rear wheel. In the same way, rotation with the central axis 21 of other wheels 2 can also be realized.

In the running state of the above-mentioned universal vehicle 100 , the rotation speed and the forward and reverse rotation of each wheel 2 are controlled by the respective drive motors 4 .

Because the utility model is provided with the wheel steering mechanism 3 on the chassis 1, the swing arm 31 of the wheel steering mechanism 3 can be used to control the rotation of the wheel 2 around the vertical steering axis 21 to realize swinging, and in the The chassis 1 is provided with an arc-shaped guide groove 12 corresponding to an angle of 180 degrees. The guide groove 12 can not only provide support for the swing arm 31, but also guide the swing arm 31 to swing 180 degrees, so that The rotation angle of the wheel 2 can reach 180 degrees. Therefore, the wheel 2 can realize straight-line walking in the forward and backward directions, lateral walking in the left and right directions, and spinning in situ, etc., so that the car can realize Universal driving, simple structure, simple control, safety and stability, and simple operation for side parking; and various driving modes. Playability is strong.

What is disclosed above is only a preferred example of the utility model, and of course the scope of rights of the utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
