DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1

[0021] A lifting and traveling structure for small electronic mobile products, such as Figure 1 and Figure 2 As shown, it includes a base 1, a lifting seat 2 is slidably arranged on the upper part of the base 1, and the left and right sides of the lifting seat 2 are both downwardly inclined arc structures, the front and rear sides of the left and right parts of the base 1 are rotatably connected with traveling wheels 3, and the traveling wheels 3 are provided with anti-slip sleeves, and the front and rear sides inside the base 1 are installed with double-axis motors 4, and the double-axis motors 4 are arranged in a front-to-back direction. The outer output shafts of the double-axis motors 4 are through-connected with the base 1, and the outer output shafts of the double-axis motors 4 are connected with rotating disks 5, and the rotating disks 5 are provided with limiting blocks. The rotating disks 5 are slidably connected with lifting frames 6, and the traveling wheels 3 are connected with connecting slot frames 7. The lifting frames 6 are slidably connected to adjacent connecting slot frames 7, and the base 1 is provided with a lifting mechanism 8 for driving the lifting seat 2 to automatically lift and adjust.

[0022] like Figure 2-Figure 4 As shown, the lifting mechanism 8 includes a bevel gear 81, which is respectively mounted on the inner output shaft of the dual-axis motor 4 and rotatably mounted on the upper side of the inner bottom of the base 1. Two mounting frames 82 are connected to the upper side of the inner bottom of the base 1. The mounting frames 82 are rotatably provided with rotating rods 83, and the rotating rods 83 are also connected to the bevel gear 81. A connecting groove rod 84 is connected to the lower side of the lifting seat 2, and the connecting groove rod 84 is slidably connected to the rotating rod 83.

[0023] It should be noted that when using this product for guiding or transporting items, the corresponding device can be placed on the lifting seat 2, and then the traveling wheel 3 can be started to allow the device to start moving freely. If the device encounters an obstacle that is inconvenient to cross during its free movement, the dual-axis motor 4 can be started, and the front and rear output shafts of the dual-axis motor 4 begin to rotate. As the front and rear output shafts of the dual-axis motor 4 rotate, the corresponding bevel gear 81 and the rotating disk 5 will be driven to rotate. The rotation of the rotating disk 5 will push the lifting frame 6 to move downward, so that the lifting frame 6 squeezes and pushes the connecting slot frame 7, so that the connecting slot frames 7 begin to approach each other, and then the traveling wheels 3 begin to approach each other, so as to achieve the effect of lifting the overall height of the device, increase the height of the lower side of the base 1, and enable the device to easily cross obstacles. At the same time, the rotation of the bevel gear 81 will cause the rotating rod 83 to rotate, so that the connecting slot rod 84 moves upward, and the upward movement of the connecting slot rod 84 will also cause the lifting seat 2 to lift upward, so as to achieve the purpose of adaptive lifting, so that the center of gravity of the entire device can be adjusted accordingly, and the stability of the device's travel is improved.

[0024] Example 2

[0025] On the basis of Example 1, Figure 2-Figure 4 As shown, a buffer mechanism 9 is also included, and the buffer mechanism 9 includes a guide groove frame 91. The left and right parts of the base 1 are connected to the front and rear symmetrical guide groove frames 91. Sliding blocks 92 are slidably arranged on the guide groove frames 91. Connecting rods 93 are rotatably arranged on the sliding blocks 92. The upper ends of the connecting rods 93 are rotatably connected to the lifting seat 2. Reset springs 94 are connected between the sliding blocks 92 and the adjacent guide groove frames 91.

[0026] It should be noted that as the lifting seat 2 starts to rise, the lifting seat 2 will drive the adjacent connecting rod 93 to rotate, so that the connecting rod 93 drives the sliding block 92 to slide along the adjacent guide groove frame 91. During the sliding process of the sliding block 92, the return spring 94 will be squeezed, thereby relying on the force of the return spring 94 to play a certain buffering and protective effect.
