For clarity of explanation of the solution of the present utility model, the front, rear, left, right, upper and lower sides of the motorcycle 100 shown in fig. 1 are also defined.

Specifically, the travel assembly 12 includes front wheels 121 and rear wheels 122, and the suspension assembly 13 includes front suspensions 131 and rear suspensions 132, with the front wheels 121 being coupled to the frame 11 via the front suspensions 131 and the rear wheels 122 being coupled to the frame 11 via the rear suspensions 132. Wherein the front suspension 131 includes a link assembly 1311 and a front shock absorber 1312, the link assembly 1311 being connected to the front shock absorber 1312, the front shock absorber 1312 also being connected to the front wheel 121.

Specifically, the upper link plate 133 is located at the lower side of the steering handle 161 in the up-down direction of the motorcycle 100, and the steering handle 161 is connected to the upper link plate 133. Specifically, the upper yoke plate 133 includes a shock absorbing mounting portion 1331, a steering mounting portion 1332, and a connecting portion 1333.

Specifically, the ratio of the area of the first projection surface to the area of the second projection surface is set to 0.15 or more and 0.22 or less. More specifically, the ratio of the area of the first projection surface to the area of the second projection surface may also be set to 0.19. Through the arrangement, the strength of the upper yoke plate 133 is prevented from being reduced due to the overlarge hollowed-out part 1334, so that the service life of the upper yoke plate 133 is prolonged, and the safety of the motorcycle 100 is further improved; the hollowed-out portion 1334 can be prevented from being too small to effectively lighten the weight of the upper yoke plate 133, and further the weight of the upper yoke plate 133 can be advantageously reduced.

By the above arrangement, the fixing device 18 can be disposed on the connection assembly 1311, and the mounting components of the fixing device 18 and the motorcycle 100 can be reduced, thereby facilitating simplification of the structure of the front side of the motorcycle 100 and improvement of the structural compactness of the motorcycle 100. In addition, through the above arrangement, under the condition that the fixing device 18 is not used, the space occupation rate of the fixing device 18 can be reduced, namely the structural compactness of the fixing device 18 is improved, so that the space utilization rate of the front side of the motorcycle 100 is improved, and potential safety hazards caused by collision between a driver and the fixing device 18 in the riding process can be avoided.

The connection between the fastening device 18 and the upper pressure piece 1311a may be embodied as a screw connection. Specifically, the fixing device 18 further includes a cover 183, and when the fixing device 18 and the upper pressing block 1311a are connected by bolts, the cover 183 can cover exposed bolts on the surface of the fixing device 18 and can be clamped with the fixing device 18, thereby improving the aesthetic property of the fixing device 18 and the flatness of the surface.

As one implementation, when the lifting mechanism 182 is in the stowed state, the upper surface of the lifting mechanism 182 is substantially flush with the upper surface of the bracket body 181. Through the above arrangement, a plane can be formed with the upper surface of the bracket body 181 when the lifting mechanism 182 is in the storage state, so that the occupied space of the lifting mechanism 182 is reduced, and meanwhile, the potential safety hazard caused by collision between a driver and the lifting mechanism 182 in the riding process is avoided, thereby improving the safety and the aesthetic property of the fixing device 18.

Wherein, the fixing member 1821 is provided therein with a connection portion having a downward opening, and the stopper 1822 is connected with the connection portion, thereby realizing the connection between the stopper 1822 and the fixing member 1821. Specifically, the fixing device 18 operates as follows:

the limiting member 1822 is fixedly connected with the fixing member 1821, when the fixing member 1821 is pressed, the fixing member 1821 is clamped with the touch switch 1824, at this time, the elastic member 1823 is in a compressed state, and the fixing member 1821 overcomes the elastic force of the elastic member 1823 under the action of the touch switch 1824 to enable the fixing member 1821 to be located in the bracket body 181, so that a plane is formed between the upper surface of the fixing member 1821 and the upper surface of the bracket body 181, and the occupied space of the fixing member 1821 is reduced. When the fixing device 18 is required to be used, the fixing member 1821 is pressed again to be separated from the switch 1824 and the fixing member 1821, and at this time, the fixing member 1821 is moved to the upper side of the bracket body 181 by the elastic force of the elastic member 1823, and the travel of the fixing member 1821 to the upper side of the bracket body 181 is limited by the limiting member 1822.

With the above arrangement, the disassembly and assembly between the portable device 200 and the motorcycle 100 can be facilitated; meanwhile, the first charging member 186 and the charging module 185 can charge the portable device 200 disposed on the motorcycle 100, thereby improving the cruising ability of the portable device 200. In addition, through the above-mentioned setting, after fixing device 18 is dismantled from coupling assembling 1311, second charging member 187 still can connect external power source to charge for portable equipment 200 through charging module 185, and then satisfy fixing device 18 and charge the diversification of portable equipment 200, be favorable to improving fixing device 18's functional diversity.
