Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of crashproof cart, in the present embodiment, crashproof cart is battery-operated motor cycle, comprises main body of vehicle frame, and the front portion of described main body of vehicle frame is front fork arm 1, and the front portion of described front fork arm 1 connects vertical tube of front fork 2.Front fork 3 is installed on vertical tube of front fork 2, and front vehicle wheel 4 is installed in the bottom of front fork 3.
Described front fork arm 1 comprises arm 1-1 and lower branch line 1-2, described upper arm 1-1 is connected with described vertical tube of front fork 2, described upper arm 1-1 and described lower branch line 1-2 are hinged by bearing pin 5, the lower end connection of described upper arm 1-1 prevents the front fork arm 1 limiting section 1-3 of bending backward, between described lower branch line 1-2 and described vertical tube of front fork 2, be provided with spring 6, the two ends of described spring 6 are hinged described vertical tube of front fork 2 and lower branch line 1-2 respectively.In the present embodiment, the upper end welding vertical tube of front fork 2 of upper arm 1-1.Described upper arm 1-1 and lower branch line 1-2 are oval, and the lower end of described upper arm 1-1 is connected by bearing pin 5 with the upper end of described lower branch line 1-2.In the present embodiment, the front portion, lower end of described upper arm 1-1 is provided with, and can to make the notch 1-4(that stretches out on the top of described lower branch line 1-2 be the width that the width of notch 1-4 is greater than lower branch line 1-2, makes the front fork arm 1 can be in bearing pin 5 places bending).The notch 1-4 rear of upper arm 1-1 is limiting section 1-3, thereby makes the bottom of front fork arm 1 be merely able to bending forward.
Under normal condition, front fork arm 1 remains stable under the effect of limiting section 1-3.In the time that the wheel 4 of front part of vehicle occurs to clash into, the lower branch line 1-2 of front fork arm 1 rotates around bearing pin 5, the bottom bend forward of front fork arm 1, distance between lower branch line 1-2 and vertical tube of front fork 2 diminishes, now be located at spring 6 between vertical tube of front fork 1 and lower branch line 1-2 and have an effect, so that impact is cushioned, impact major part is absorbed by spring 6, thereby avoid front fork 3 and vehicle frame impaired, prevent to lose control of one's vehicle.
On described lower branch line 1-2, baffle plate 7 is installed.When the distance between vertical tube of front fork 2 and lower branch line 1-2 is because of after shock narrows down to certain degree, baffle plate 7 contacts with front vehicle wheel 4, and now impact is all applied on front vehicle wheel 4, avoids being out of shape between vertical tube of front fork 1 and vehicle frame excessive and damages front fork 3 and vehicle frame.
Rear wheel 8 is installed at the rear portion of main body of vehicle frame, and vehicle seat 9 is installed on described main body of vehicle frame, and the both sides of vehicle seat 9 are provided with safety strap 10, and the end of safety strap 10 connects the buckle that can mutually fasten.Vehicle driver is sitting on vehicle seat 9, and the safety strap of vehicle seat 9 both sides is walked around driver's waist, and the waist front that is buckled in driver fastens, and when collision happens, safety strap 10 can prevent human body play forward, avoids accident to produce.In the present embodiment, on main body of vehicle frame, with the cavity 11 of being located at vehicle seat 9 belows, described safety strap 10 is accommodated in described cavity 11, and safety strap 10 is connected in cavity 11, when safety strap 10 does not use, can be accommodated in cavity 11, avoid safety strap 10 to affect vehicle appearance.Vehicle seat 9 can be dug, and digs vehicle seat 9 and can open cavity 11 and take out safety strap 10.
Above-mentioned embodiment is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model; if front fork arm is one-piece construction; vertical tube of front fork and front fork arm are hinged by bearing pin; and vertical tube of front fork or front fork arm are provided with the limiting section that prevents that vertical tube of front fork from rotating backward around bearing pin, within all dropping on protection domain of the present utility model.
