Abstract
The utility model relates to a shock-absorbing composite vehicle frame structure, which is composed of a chassis and a seat bracket, wherein the chassis is composed of a back wheel cross shaft and a longitudinal beam which is fixedly provided with the back wheel cross shaft and connected with a front wheel or a longitudinal beam which is fixedly provided with the back wheel cross shaft and connected with a cross shaft of the front wheel. The seat bracket is composed of two supporting arms with the upper end fixedly installed at both sides of the seat, the lower end fixedly arranged at the cross shaft of the back wheel, the supporting arms cause the back end of the seat to be in a cantilever state, and a shock absorber provided with a damping is fixed between the lower surface of the seat and the longitudinal beam. The back end of the seat of the vehicle frame is in the cantilever state, the supporting arm of the seat has elasticity, and the seat forms first level shock absorption; the shock absorber with the damping is arranged on the front end of the lower surface of the seat, when the chassis meets with larger shock, the shock absorber can absorb the shocking potential energy of the chassis to form second level shock absorption. Thus, the vehicle frame has the advantages of composite shock absorption effect, favorable shock absorption performance and comfort for riders to sit.
Description
Technical field
This utility model relates to a kind of composite shock-absorbing body frame structure for automotive.
Background technology
At present, medical care with tricycle, carriage in the park, sanatorium, sanatorium be much, have among them pedal, that hand push is arranged, have electronic.The medical care of hand push at the car pusher by medical personnel with car, allows the patient that recuperates take a bus instead of walking, and Time for Sunshine is had a breath of fresh air; The patient of legs and feet health can be pedaled the car of chain, slowly to take exercise, regains one's strength; Electrodynamic car is arranged, driving shaft is put into trailing wheel or front-wheel, directly be put in wheel hub by drive mechanism or drivewheel, promoting garage advances, gauge tap then is put on the armrest, and the occupant is the gauge tap button at any time, handle car move ahead, retreat, about turn.The seat of above-mentioned these cars is fixed on the vehicle frame, the vehicle frame poor flexibility, as jolt, the person of taking advantage of feels discomfort very much.
The utility model content
The purpose of this utility model is to improve the shortcoming of prior art and a kind of composite shock-absorbing body frame structure for automotive is provided.
For achieving the above object, this utility model is taked following design: this utility model is to be used for various medical care cars, the body frame structure for automotive of tricycle etc., it is made up of chassis and seat support, described chassis by rear wheel lateral axle and with the be solidly installed longeron that is connected front-wheel or form of rear wheel lateral axle with this rear wheel lateral axle longeron that is connected the front-wheel transverse axis that is solidly installed; Described seat support is packed in seat both sides, lower end by the upper end and is packed on the rear wheel lateral axle two support arm that the seat rear end becomes cantilever position and the amortisseur with damping that is fixed between seat seat support lower surface and the longeron are formed.Described chassis is installed the amortisseur with damping by rear wheel lateral axle, front-wheel transverse axis and the I shape frame that longeron is formed between seat support lower surface and longeron; Described chassis is installed two amortisseurs with damping by rear wheel lateral axle, front-wheel transverse axis and two I shape framves that longeron is formed between seat support lower surface and longeron; The T font frame that described chassis is made up of a rear wheel lateral axle and a longeron that is directly connected in front-wheel is installed the amortisseur with damping between seat support lower surface and longeron; The T font frame that described chassis is made up of rear wheel lateral axle and two longerons that are directly connected in front-wheel is installed two amortisseurs with damping between seat support lower surface and longeron; The U font that the described support arm that makes the seat rear end become cantilever position becomes the font or lies on one's side.Quote embodiment respectively at different automobile types below body frame structure for automotive is described.
The rear end of this vehicle frame seat becomes cantilever position, and the seat support arm has elasticity, makes seat form the one-level damping; Amortisseur with damping is installed in seat support lower surface front end, runs into bigger jolting as chassis, and this amortisseur can absorb the potential energy of chassis vibrations, constitutes the secondary damping, so this vehicle frame has the composite shock-absorbing effect.
The utility model has the advantages that: body construction is simple, damping performance good, occupant comfort.

The specific embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, the car body that this utility model constitutes is by wheel 1, chassis 2, seat 3, and seat support 4, amortisseur 5 and pedal 6 are formed.Described chassis 2 is by two crossbeams 21,22 and I shape framves that longeron 23 is formed, two drivewheels 11 are equipped with at the back rest 22 two ends among two crossbeams respectively, 12, two driven pulleys 13 are equipped with at its front-axle beam 21 two ends respectively, 14, this two driven pulley can be done 360 ° rotation at horizontal plane, described seat 3 is by seat support 31, the chair back 32 is formed, seat support 4 is seat support 31, the chair back 32 is combined, two handrails 41 of forming seat as the some of support 4, the downward lower end 42 along long end is a support of two handrails is fixed together with the back rest 22, described amortisseur 5 is fixed between seat support 31 lower surfaces and the longeron 23, pedal 6 is fixed on the seat support 4, be provided with groove 61 upwards in the middle of it, so that described longeron 23 therefrom passes through.The car that this body frame structure for automotive is formed can be carried out from the back by medical personnel, also control device can be installed on handrail, controls the electronic drivewheel of the back rest by the person of taking advantage of and advances.The seat good springiness of this body construction, no matter garage is on which kind of road surface, and amortisseur can absorb the potential energy of chassis vibrations, makes the seat held stationary.
Embodiment 2
As shown in Figure 3, the car body of this utility model formation is made up of wheel 1, chassis 7, seat 3, seat support 8, amortisseur 5 and power foot-treadle device 20.Described chassis 7 is by a crossbeam 71 and the T font frame that longeron 72 is formed, two driven pulleys 11,12 are equipped with at the two ends of crossbeam 71 respectively, the centre of crossbeam 71 is provided with a square bearer 711, the flywheel 201 of a cantilever is housed in this square bearer, it is connected with axis wheel disc 203 on being rotatably mounted to longeron 72 with chain 202, so that the rider rides.The front end of its longeron 72 is fixed with a preceding fork 9, should a wheel 13 be housed preceding fork 9 lower ends, a steering wheel 10 is equipped with in the upper end, with turning to of control front-wheel, described seat 3 is made up of seat support 31, the chair back 32, as two handrails 81 of the part of support 8 seat support 31, the chair back 32 are combined, two handrails downward along long end, the lower end 82 that is support is consolidated with crossbeam 71, and described amortisseur 5 is fixed between seat support 31 lower surfaces and the longeron 72.The car that this body construction is formed can be advanced by occupant oneself operation.
