Abstract

Provided is an elastic hinge of a vehicle overturn seat support, particularly relating to a hinge. The hinge includes a hinge arm, an elastic hinge shaft, and a hinge base, the hinge arm is fixedly connected to the seat support, the hinge base is fixed on the vehicle body, the shaft sleeve of the hinge arm is sleeved on the elastic hinge shaft, the elastic hinge shaft is arranged on the hinge base, and the hinge arm can move up and down surrounding the hinge base via the elastic hinge shaft. The elastic hinge shaft includes a pin shaft, a washer, a latch pin, and two vibration damping rubber linings, the two vibration damping rubber linings are oppositely arranged between the two side plates of the hinge base, the shaft sleeve of the hinge arm is sleeved on the external circumference of the vibration damping rubber linings; the pin shaft serially connects the two vibration damping rubber linings and locks by passing through the washer and by penetrating through the latch pin of the pin shaft. The elastic hinge provided is significant in effect and can improve the driving comfortableness; moreover, the elastic hinge provided has the properties of simple structure, low production cost, and high reliability, as well as can be widely applied to vehicles such as fork trucks or miniature vehicles.

Description

Vehicle turnover supporting base of seat elastic hinge

Technical field

The utility model relates to a kind of hinge, particularly a kind of vehicle turnover supporting base of seat elastic hinge that is used for vehicles such as fork truck and minicar.

Background technology

At present part vehicle motors such as fork truck, minicar are positioned at below the operator's compartment, and driver seat is directly installed on the cover of the turning activity of driving engine, and the driving engine cover is used as the supporting seat of seat, and supporting base of seat is by hinge and body contact.Conventional seat supporting seat hinge arrangement mostly is simple loose-leaf system, supporting base of seat is by this loose-leaf system hinge and vehicle body mechanical rigid or semi-rigid the connection, the transfer of vibration of vehicle body and driving engine effectively can not decay, particularly travel and driving engine during at uneven road surface in the big operating mode of amplitudes such as startup, idling, acceleration at vehicle, its vibration is obvious, and comfort is lower.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of vehicle turnover supporting base of seat elastic hinge with vibration-damping function, to solve the weak point that above-mentioned vibration is obvious, traveling comfort is low that prior art exists.

The technical scheme that solves the problems of the technologies described above is: a kind of vehicle turnover supporting base of seat elastic hinge, this hinge comprises hinge arms, elastic hinge axle and hinge base, described hinge arms is captiveed joint with supporting base of seat, hinge base is fixed on the vehicle body, the axle sleeve of hinge arms is socketed on the elastic hinge axle, the elastic hinge axle mounting is on hinge base, and hinge arms can be up and down around hinge base by this elastic hinge axle.

Further technical scheme of the present utility model is: described elastic hinge axle comprises bearing pin, packing ring, latch and two vibration isolation rubber linings, described two vibration isolation rubber linings are installed between two blocks of side plates of hinge base relatively, and the axle sleeve of hinge arms is socketed on the cylindrical of this vibration isolation rubber lining; Described bearing pin is serially connected two vibration isolation rubber linings, and by packing ring, the latch locking of passing bearing pin.

Because adopt said structure, the vehicle turnover supporting base of seat elastic hinge of the utility model compared with prior art has following beneficial effect:

1, can reduce vibration, raising traveling comfort by bus:

Because hinge axis of the present utility model adopts the elastic hinge axle, vibration isolation rubber lagging material in this elastic hinge axle can adopt the rubber of good weatherability, as EP rubbers, butyl rubber etc., hardness can be adjusted according to size, the quality of supporting base of seat, when work, pass through the distortion of rubber and give birth to heat, to reach the purpose of vehicle body that decay driving engine and uneven road surface cause and seat vibration transmission, simultaneously owing to adopt elasticity to connect, can reduce the natural frequency of supporting base of seat total system, avoid producing high-frequency resonance.Therefore, effectiveness in vibration suppression of the present utility model is very obvious, can obviously improve driver comfort.

2, simple in structure, the reliability height:

Of the present utility model relatively simple for structure, its productive costs is lower, and reliability is higher, is easy to apply.

Below, the technical characterictic to the vehicle turnover supporting base of seat elastic hinge of the utility model is further described in conjunction with the accompanying drawings and embodiments.

The specific embodiment

Embodiment one:

Disclosed among Fig. 1～Fig. 2 is a kind of vehicle turnover supporting base of seat elastic hinge, and this hinge comprises hinge arms 1, elastic hinge axle 2 and hinge base 3, and described hinge arms 1 is captiveed joint with supporting base of seat, and hinge base 3 is fixed on the vehicle body; Described elastic hinge axle 2 comprises bearing pin 201, packing ring 202, latch 203 and two vibration isolation rubber linings 204, described two vibration isolation rubber linings 204 are installed between two blocks of side plates 301 of hinge base 3 relatively, and the axle sleeve 101 of hinge arms 1 is socketed on the cylindrical of this vibration isolation rubber lining 204; Described bearing pin 201 is serially connected two vibration isolation rubber linings 204, and by packing ring 202, latch 203 locking of passing bearing pin 201; Hinge arms 1 can be up and down around hinge base 3 by this elastic hinge axle 2.

As a kind of conversion of present embodiment one, described elastic hinge axle can also be other structure that includes the rubber material.
