In this way, the kart frame has no circuit control board, does not need to install batteries, does not need to download mobile phone APPs, and does not need Bluetooth pairing or installation of any communication lines; when installing, just put the barless balance car 400 into the power assembly mechanism 100 .

What needs to be explained here is that the left shaft 103 and the right shaft 104 are located outside the balance car 400, which means that the left shaft 103 is located on the left side of the left wheel 403 of the balance car 400, and the right shaft 104 is located on the right wheel of the balance car 400. 404 on the right side.

In other embodiments, the self-balancing vehicle 400 can also be installed at the front end of the kart frame, and the corresponding assembly mechanism 100 is also located at the front half of the frame body.

In this embodiment, the frame body includes a main support frame 501, a seat part 502 and a connecting frame 503, the wheels and the main supporting frame 501 are installed on the front and rear ends of the connecting frame 503 respectively, and the seat part 502 is fixed Installed above the main support frame 501, the left and right sides of the assembly mechanism 100 are respectively hinged to the main support frame 501 through the left shaft 103 and the right shaft 104; further preferably, two wheels are installed on the front end of the connecting frame 503, The wheels are universal wheels, and in other embodiments, only one wheel can be installed on the front end of the connecting frame 503 .

In this embodiment, the assembly mechanism 100 includes a left assembly frame 105, a right assembly frame 106, a left fixing part 107 and a right fixing part 108;

The left fixing part 107 is installed on the left assembly frame 105 and is fixedly connected with the left platform of the balancing vehicle 400, the left contact part 101 is installed on the left assembly frame 105; the right fixing part 108 is installed on the right assembly frame 106 and fixedly connected with the right platform of the balance car 400, the right contact piece 102 is installed on the right assembly frame 106;

The left assembly frame 105 is hinged to the main support frame 501 through the left rotating shaft 103 , and the right assembly frame 106 is hinged to the main support frame 501 through the right rotating shaft 104 .

It should be noted here that the left rotating shaft 103 can be fixedly connected or integrally formed with the left assembly frame 105, or can be fixedly connected or integrally formed with the main support frame 501; the right rotating shaft 104 can be fixedly connected or integrally formed with the right assembly frame 106. integrally formed, and may also be fixedly connected or integrally formed with the main support frame 501; and;

Considering that the left rotating shaft 103 and the right rotating shaft 104 are the main force receiving parts, the left rotating shaft 103 and the right rotating shaft 104 have relatively high strength.

In this embodiment, the central axis of the left rotating shaft 103 is parallel to the ground and its height above the ground is H1; The central axis of the balance car is parallel to the ground and its height from the ground is H3, the rotation central axis of the right wheel 404 of the balance car is parallel to the ground and its height from the ground is denoted as H4;

Among them, H1≤H2+3cm, H3≤H4+3cm.

And, the central axis of the left rotating shaft 103 is distributed parallel to the central axis of rotation of the left wheel 403 of the self-balancing vehicle, the projection line of the central axis of the left rotating shaft 103 on the horizontal plane and the projection of the central axis of rotation of the left wheel 403 of the self-balancing vehicle on the horizontal plane The distance between the lines is less than or equal to 3 centimeters; the central axis of the right rotating shaft 104 is distributed parallel to the rotating central axis of the right wheel 404 of the balance car, and the projection line of the central axis of the right rotating shaft 104 on the horizontal plane is the same as that of the right wheel 404 of the balance car. The distance between the projection lines of the rotation center axis on the horizontal plane is less than or equal to 3 cm.

Or; the distance between the center axis of the left shaft 103 and the center axis of rotation of the balance car 400 left wheel 403 is no more than 3 cm, and the center axis of the right shaft 104 and the center axis of rotation of the right wheel 404 of the balance car 400 Compared with the existing karts of the same type, the distance between the center axis of the rotating shaft and the rotation center axis of the wheel of the balance car 400 has been reduced by at least 3 cm, thereby slowing down the balance when the balance car 400 swings. The interference produced by the overall movement of the vehicle frame; further preferably, the distance between the central axis of the left rotating shaft 103 and the central axis of rotation of the left wheel 403 of the balance car 400 is no more than 1 cm; the central axis of the right rotating shaft 104 and the balance car 400 The distance between the rotation center axes of the right wheel 404 is not more than 1 cm; in this way, the interference with the overall movement of the vehicle frame when the balance vehicle 400 swings is greatly reduced.

The projection line of the center point of the left rotating shaft 103 and the center point of rotation of the left wheel 403 of the balance car 400 is parallel to the line of gravity of the earth on the side view of the car body; The projection line of the connecting line between the rotational center points of the right wheels 404 on the side view plane of the vehicle body is parallel to the gravity line of the earth.

As most preferably, the central axis of the left rotating shaft 103 is distributed coaxially with the central axis of rotation of the left wheel 403 of the balance car 400; the central axis of the right rotating shaft 104 is distributed coaxially with the central axis of rotation of the right wheel 404 of the balance car 400;

Such setting is because in the current go-karts that use the balance car 400 as the rear driving force, due to structural constraints, the swing center axis of the assembly mechanism 100 and the rotation center axis of the balance car 400 wheels are often separated by more than 5cm, while the assembly mechanism 100 It forms an integral body with the balance car 400 through a fixed connection. In this way, when the assembly mechanism 100 is operated to swing, there will be two rotating central axes, and these two rotation axes will cause the difference between the swing of the assembly mechanism 100 and the swing of the balance car 400. There is motion interference between the two rotating shafts, and the larger the distance between the two rotating shafts, the stronger the motion interference; and the current go-kart mainly relies on strong force to distort the 400 balance car and the 1073 connecting parts to eliminate the motion interference, so the kart’s The operation resistance is very large, and the parts of the balance car 400 are seriously worn; and when the swing center axis of the assembly mechanism 100 is coaxially distributed with the rotation center axis of the wheels of the balance car 400, the height of the center of gravity of the frame will not be caused when the balance car 400 is operated to swing back and forth. The change with the horizontal position avoids the need to overcome the gravity to do work due to the change of the height of the center of gravity of the frame during manipulation, and also avoids interference and conflict with the overall movement of the balance car 400 when it swings. Component wear is minimal.

It is worth noting that, for the same balance car 400, the positions of the left rotation shaft 103 and the right rotation shaft 104 can be designed to be coaxial with the left and right wheels 404 of the matched balance car 400, but the current balance The car 400 mainly includes 6.5-inch self-balancing car 400, 8.5-inch self-balancing car 400 and 10-inch self-balancing car 400. Since the assembly mechanism 100 is fixedly mounted on the self-balancing car 400 by clamping, the left shaft 103 and The coaxiality between the right rotating shaft 104 and the wheels of the balancing car 400 in the horizontal direction will not change due to the size change of the balancing car 400, but in order to ensure that the left rotating shaft 103 and the right rotating shaft 104 are vertically aligned with the wheels of the balancing car 400 Coaxiality, in this embodiment, the assembly mechanism 100 also includes an adjustment assembly 109 for adjusting the height of the assembly mechanism 100 from the ground, so that the left rotation shaft 103 and the right rotation shaft 104 have three installation positions with different heights, Corresponding to the 6.5-inch balance car 400, 8.5-inch balance car 400 and 10-inch balance car 400 respectively; and has two different implementation methods:
