In one embodiment, as shown in fig. 1 to 8, a second axle mounting seat 802 is provided on the middle shell 50 for mounting the second wheel 80, and more specifically, the second wheel 80 includes a second axle 801, the middle shell 50 is provided with the second axle mounting seat 802, and the second axle mounting seat 802 includes a second axle sheet fixing hole 803 and a second axle mounting groove 804; the second axle mounting slots 804 are adapted to the second axle, the second axle is placed in the second axle mounting slots, the second axle holding holes 803 include two sets, and the two sets of second axle holding holes 803 are symmetrically disposed on both sides of the second axle mounting slots 804. A second axle pressing sheet 805 is further arranged on the second axle mounting seat 802, and the second axle is fixed in the second axle mounting groove through the second axle pressing sheet 805; the second axle pressing plate 805 is fixedly connected with the second axle mounting seat 802 through screws, so that the second axle is prevented from being separated from the second axle mounting groove. Preferably, the thickness of the middle case 50 is greater than that of the second upper case 30; because the middle shell 50 has a relatively thick thickness and relatively high mechanical strength, in the specific example shown in fig. 2, 3 and 8, the second axle mounting seat is arranged at the bottom of the middle shell 50, so that the second axle can be more firmly mounted, and the second wheel can more stably drive the second vehicle body 2 to operate.

In this way, the structure of the middle shell 50 can be simplified, so that the second upper shell 30 and the middle shell 50 can be more conveniently installed, and assembly errors can be avoided; and through the second control panel connecting column 304, the connection between the second upper shell 30 and the middle shell 50 is tighter, which is beneficial to improving the mechanical strength of the second vehicle body 2, thereby improving the stability of the whole balance vehicle. In order to make the installation of the second control board 5 more secure, the second control board connection posts 304 include two sets, and the two sets of second control board connection posts 304 are respectively disposed on two sides of the second axle mounting seat 802, so that the second control board 5 does not interfere with the second axle mounting seat 802.

Since the middle shell 50 is disposed below the second upper shell 30, the second axle mount 802 disposed on the lower surface of the second upper shell 30 easily interferes with the middle shell 50, and therefore, according to this embodiment, as shown in fig. 9 and 10, preferably, the middle shell 50 is provided with the first through-groove 503, the second axle mount 802 passes through the first through-groove 503 and is located below the middle shell 50 so as not to interfere with the middle shell 50, and at this time, the second axle is also located below the middle shell 50, and the second axle mount 802 fixes the second axle in the second axle mount groove 804 through the second axle pressing piece 805. The second axle mounting seat 802 is arranged on the second upper shell 30, and compared with the existing upper shell structure, only a second control panel connecting column and a second contact through hole on the second upper shell 30 are eliminated, so that the production process is simplified, waste is avoided, and the second upper shell 30 and the second axle are conveniently mounted. Preferably, the first through-slot 503 on the middle shell 50 has an opening facing the second wheel, so that the second upper shell 30 and the second axle can be installed first, and then the second axle mounting seat 802 is directly passed through the first through-slot 503, and the installation is simpler and more convenient. Meanwhile, the second axle mounting seat 802 and the second upper shell 30 are equivalent to limiting the middle shell 50 left and right, so that the middle shell 50 and the second shell are connected more tightly, and the second vehicle body 2 has better and more stable mechanical strength.
