The arbitrary and all combination of the Listed Items of pass.
Refering to Fig. 1 and Fig. 2, first embodiment of the invention provides a kind of motorcycle 100, including shield thick stick 10, vehicle frame 30 and hair
Motivation 40.Vehicle frame 30 includes vertically arranged supervisor 31 and the girder 32 that laterally sets, one end of girder 32 be responsible for 31 it is upper
End connection, the other end branch of girder 32 form both sides pipe 321, receiving space 50 are formed between supervisor 31 and girder 32, is started
Machine 40 is contained in receiving space 50, and engine 40 includes suspension plate 41, and engine 40 is connected by suspension plate 41 and supervisor 31
Connect.
Shield thick stick 10 includes horizontal pillar 110, is distributed in the first perpendicular perpendicular pillar of pillar 120 and second of horizontal 110 both sides of pillar
130, the lower end of the first perpendicular pillar 120 is connected with the lower end of the second perpendicular pillar 130 (erects the lower end of the first perpendicular pillar 120 with second
The lower end of pillar 130 can be directly connected to, and can also be indirectly connected with by miscellaneous part), the upper end of the first perpendicular pillar 120 and the
The upper end of two perpendicular pillars 130 is connected with horizontal pillar 110 and relative closure space, the both ends of horizontal pillar 110 is formed between three
Be respectively relative to the first perpendicular pillar 120 with second it is perpendicular pillar 130 is opposite extends to form suspending part 111, respectively the first suspending part
1111 and second suspending part 1112, the first suspending part 1111 and the second suspending part 1112 are with the center symmetric setting of horizontal pillar 110.
Specifically, the first perpendicular pillar 120 is integrally formed with the second perpendicular pillar 130.In other embodiments, the first perpendicular pillar 120 and the
