Description
Technical field
This utility model relates to a kind of automobile rear seat, especially relates to a kind of back row seat of automobile
Chair back torsion spring structure.
Background technology
At present automobile rear-row seat-backrest reset power-assisted mainly uses Wind spring structure, but Wind spring structure
More complicated, cost is higher.
Torsion spring can provide power-assisted equally, but applies less.
Utility model content
For solving problem above, this utility model provides a kind of simple in construction, and synchronicity is good,
Convenient manufacture, and low price, automobile rear-row seat-backrest torsion spring structure applied widely.
The technical solution adopted in the utility model is: a kind of automobile rear-row seat-backrest torsion spring structure,
Including the backrest backplate being arranged at seat both sides, it is characterised in that: the backrest backplate of described both sides
Bottom is all fixed with torsion spring fixed support, and the torsion spring that the two ends of torsion spring are separately mounted to both sides is solid
On fixed rack；The edge of the backrest backplate of described both sides is respectively provided with inside flange, described torsion spring
One end act against on the flange of backrest backplate of side, the other end of torsion spring and seat support are solid
Fixed.
As preferably, described torsion spring fixed support is equipped with torsion spring mounting groove, described torsion spring two
End is each passed through torsion spring mounting groove and is arranged on fixing of the torsion spring of both sides by stator and rivet
On frame.
As preferably, the torsion spring fixed support of the backrest backplate bottom of described both sides is symmetrical arranged.
As preferably, described torsion spring includes round end and fixing end, described round end and fixing end
In upper and lower inverse bending, described round end is presented bending and acts against the turning over of backrest backplate of side
Bian Shang, described fixing end is lower bending and is fixed on seat support.
As preferably, the fixing end of described torsion spring is fixed with seat support by lining and fixed block.
This utility model obtains and provides the benefit that: this utility model is by back seat backrest
The bottom of the backrest backplate of both sides arranges torsion spring, and one end maintains static, and the other end acts against
Move with backrest backplate on the flange of backrest backplate, when back seat rotates, torsion spring energy
Enough for back seat offer restoring force.This utility model simple in construction, synchronicity is good, manufacturer
Just, and low price, the most applied widely.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As Figure 1-4, a kind of automobile rear-row seat-backrest torsion spring structure of the present utility model,
Including backrest backplate 1, torsion spring 3, torsion spring fixed support 2 and stator 4, backrest backplate 1
Be arranged on the both sides of back seat, folding can be overturn, the edge of backrest backplate 1 be respectively provided with to
Inside it is bent into the flange 1-1 of 90 °；It is respectively welded one in the bottom of the backrest backplate 1 of both sides
Individual torsion spring fixed support 2, the torsion spring fixed support 2 of both sides welds symmetrically.
Torsion spring 3 includes round end 3-1 and fixing end 3-2, round end 3-1 and fixing end 3-2
Inverse bending up and down, round end 3-1 is upper bending one section, by the torsion spring fixed support of side
2 are arranged on backrest backplate 1 bottom acts against on the flange 1-1 of backrest backplate 1 front end；Fixing
End 3-2 is lower bending one section, is arranged on backrest backplate by the torsion spring fixed support 2 of opposite side
1 bottom, is then fixed with seat by fixed block 6, in order to prevent in torsion spring 3 motor process
Torsion spring fixing end 3-2 owing to firmly contacting generation abnormal sound, fixes end 3-2 at torsion spring with fixed block 6
And lining 7 is installed between fixed block 6.
Torsion spring fixed support 2 has torsion spring mounting groove and torsion spring fixing hole, on stator 4
Having torsion spring installing hole and torsion spring fixing hole, torsion spring mounting groove is the most right with torsion spring position of mounting hole
Should, round end 3-1 and fixing end 3-2 is each passed through torsion spring mounting groove and the torsion spring installation of both sides
Kong Hou, is completed and the installation of torsion spring fixed support 2 by the rivet 5 in torsion spring fixing hole, turns round
After spring 3 installation, there is certain pretightning force.
As it is shown in figure 5, after backrest installation, when backrest is in right end position, now torsion spring
3 exist torsional deflection, and backrest is applied a power forward；When backrest rotates centre position,
Now backrest is exactly in vertical position；When backrest turns to left position, the positive benefit of torsion spring 3
In naturalness, no longer backrest is applied power.
When backrest is rotated centre position by right end position, backrest needs to overcome self gravitation to do work,
Now torsion spring 3 releases energy, and provides revolving force to backrest.
Backrest is turned to left position by centre position, and backrest self gravitation does positive work, adds
The moment of torsion of torsion spring 3, fully achieves the purpose of upset.
After backrest reaches left position, backrest self gravitation does positive work, and torsion spring 3 is in free shape
State, until being turned to extreme lower position.
