Background

In the automobile industry, heavy trucks occupy a very important position, trucks from logistics, freight transportation, furniture and other industries appear on roads in the current rapidly-developed internet of things era, and the reflection of automobile safety is very important along with the increasing demand of the heavy trucks. In 1956, new China manufacture released CA10 truck, from which the "made in china" preface was opened. CA 10's seat adopts through-type design, and plank + spring + filler + synthetic leather have just become the seat at present, but to the people at present, lack the constraint of safety belt and simple and easy seat skeleton design, turn at the in-process that traveles, and the driver and passenger is thrown away very easily, directly influences controlling of vehicle, and personal safety does not have the way to be ensured. At this time, each large automobile manufacturer recognizes the serious problem, and how to improve the comfort and safety protection of the seat belt becomes a breakthrough point of each large automobile manufacturer, wherein the material selection, the welding process, the structural design, the assembly design and the like of the seat framework are important factors influencing the safety performance of the whole framework assembly.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a rational in infrastructure, safety and stability's heavy truck seat skeleton assembly of frame-type.

In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of frame-type heavy truck seat skeleton assembly, including seatpad skeleton and back skeleton, this back skeleton rotates and sets up on the seatpad skeleton its characterized in that: the backrest framework comprises a backrest tube frame and backrest support steel wires, wherein the two sides of the backrest tube frame are provided with side wing support steel wires, the side wing support steel wires are single bent steel wires, two ends of each single bent steel wire are welded on the backrest tube frame, and an included angle formed between a plane where the side wing support steel wires are located and a plane where the backrest tube frame is located is 100 degrees +/-2 degrees; the backrest support steel wire comprises two transverse steel wires and two longitudinal steel wires which are staggered with each other and arranged in a # -shape, the staggered points of the two transverse steel wires and the two longitudinal steel wires are welded with each other, and the end parts of the two transverse steel wires and the two longitudinal steel wires are welded on the backrest pipe frame; and a unilateral angle adjuster and a reset coil spring are arranged between the backrest framework and the seat cushion framework.

The maximum torque of the reset coil spring is 40.55N.m, and the pre-tightening state torque of the reset coil spring is 18.9 N.m.

The utility model has the advantages that the improved frame type heavy truck seat frame assembly improves the comfort and safety protection of the seat belt by arranging the side wing supporting steel wire with reasonable angle; the backrest support steel wire cancels the originally designed backrest curtain, is changed into two transverse steel wires and two longitudinal steel wires, increases the welding seams between eight steel wires and a backrest pipe frame and the welding seams between four transverse steel wires and four longitudinal steel wires, greatly increases the support strength and the stability of the backrest steel wire, lightens the weight of the whole backrest to a certain extent, and promotes light production; the angle adjuster is omitted, a synchronizing rod and a right angle adjuster are omitted (the original design is high in cost of the double-side angle adjuster, the synchronizing rod is required to be connected synchronously, and the connection is inconvenient, and the backrest angle is adjusted and reset by utilizing the light weight and the stability of the backrest frame and adopting a welding assembly of the single-side angle adjuster.

Drawings

The following describes the present invention in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. In the embodiment, the frame type heavy truck seat frame assembly comprises a seat cushion frame 1 and a backrest frame 2, wherein the backrest frame 2 is rotatably arranged on the seat cushion frame 1, the backrest frame 2 comprises a backrest tube frame 3 and backrest support steel wires 4, side wing support steel wires 5 are arranged on two sides of the backrest tube frame 3, the side wing support steel wires 5 are single bent steel wires, two ends of the single bent steel wire are welded on the backrest tube frame 3, an included angle formed between a plane where the side wing support steel wires 5 are located and a plane where the backrest tube frame 3 is located is 100 degrees +/-2 degrees, the design supports a lateral force when a driver bends over, and the comfort of the driver is improved by combining with backrest foam; the backrest support steel wire 4 comprises two transverse steel wires 6 and two longitudinal steel wires 7 which are staggered with each other and arranged in a # -shape, staggered points of the two transverse steel wires 6 and the two longitudinal steel wires 7 are welded with each other, and the end parts of the two transverse steel wires are welded on the backrest tube frame 3, so that the originally designed backrest curtain is cancelled, the two transverse steel wires 6 and the two longitudinal steel wires 7 are changed, welding seams between eight steel wires and the backrest tube frame 3 and welding seams between four transverse steel wires and four longitudinal steel wires are increased, the support strength and the stability of the backrest steel wires are greatly increased, the weight of the whole backrest is reduced to a certain extent, and light-weight production is promoted; a unilateral angle adjuster 8 and a reset coil spring 9 are arranged between the backrest framework 2 and the seat cushion framework 1, a synchronous rod of the angle adjuster and a right-side angle adjuster are omitted (the original design of the bilateral angle adjuster is high in cost and inconvenient to connect synchronously by the synchronous rod, and the adjustment and the reset of the backrest angle are realized by utilizing the light weight and the stability of the backrest framework and adopting a unilateral angle adjuster welding assembly.

As a further preferred embodiment, the maximum torque of the return coil spring 9 is 40.55n.m, and the pre-tightening state torque of the return coil spring 9 is 18.9n.m, so as to ensure the backrest to adjust the rebound.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
