Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and examples.

Example (b): as shown in fig. 1 and 2, a balance car with a rotating shaft fixing structure comprises a motor wheel 1, a battery 4, a main control board 5, and a left pedal 2 and a right pedal 3 which are symmetrically arranged. Left and right footboard 2, 3 all include upper cover 6 and lock lower cover 7 in 6 bottom surfaces of upper cover, and upper cover 6 and lower cover 7 all adopt engineering plastics to make, and the texture is durable and the quality is light.

Be provided with the battery jar in the upper cover, battery 4 installs in the battery jar, and main control board 5 installs in upper cover 6 simultaneously, and lower cover 7 lock is in the bottom surface of upper cover 6, during the maintenance, unpacks lower cover 7 apart and can overhaul inside electronic components and parts and battery 4 etc. very conveniently. The one end that upper cover 6 and lower cover 7 lie in meeting of left footboard 2 and right footboard 3 is provided with semi-circular pivot groove 61, installs the pivot 8 of connecting left footboard 2 and right footboard 3 in the pivot groove 61, and pivot groove 61 both sides and bottom surface are provided with the strengthening rib of a plurality of criss-cross arrangements, increase the support intensity.

8 both ends of pivot and middle part are provided with the recess, install clamp 81 in the recess, and wherein the cover is equipped with axle sleeve 9 on the pivot 8 between two clamps 81, be provided with in the pivot groove 61 and hold clamp 81's space has so realized the connection and the relative rotation of two footboards, and clamp 81 and pivot groove 61 can effectively prevent the axial displacement of pivot 8 and axle sleeve 9.

Since the rotating shaft 8 is located on the bottom surface of the upper cover 6 during use, the upper cover 6 needs to bear radial force from the rotating shaft 8, and the fixation of the rotating shaft 8 on the upper cover 6 is very important. In the prior art, the fixing plate covers the rotating shaft groove 61 of the upper cover 6, the rotating shaft 8 is tightly pressed in the rotating shaft groove 61 by the fixing plate, but the fixing plate is connected with the upper cover 6 through the screw 65, the upper cover 6 is made of plastic, the screw hole has low strength, and the phenomena of thread slipping, cracking of the threaded hole and deformation are easy to occur after long-term use. In the balance car according to this embodiment, two left and right receiving holes 63 are provided in the upper cover 6 at positions on both sides of the rotating shaft groove 61, a fixing block 64 is installed in the receiving holes 63, and a threaded hole is provided in the fixing block 64. One end of the rotating shaft 8 is buckled with a rotating shaft pressing plate 82, the rotating shaft pressing plate 82 is integrally in a bridge arch shape, the middle of the rotating shaft pressing plate is upwards protruded to accommodate the rotating shaft 8, two sides of the rotating shaft are flat plates 822, and the flat plates 822 are connected with the fixing blocks 64 through screws 65.
