Detailed Description

The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 10, the special seat for three-wheel or four-wheel electric vehicles comprises a seat 1 and a backrest 2, wherein the backrest 2 is a door-shaped frame 202, then a sponge is arranged in the frame 202, an outer skin 201 is covered on the frame, two lower ends of the frame 202 are respectively fixed with a mounting bent plate 3, the opening of the mounting bent plate 3 faces forward, each mounting bent plate 3 is hinged on a mounting plate 9 through a hinge shaft 4, the left mounting plate and the right mounting plate 9 are totally two, a large arm 6 is coaxially hinged on the hinge shaft 4, the hinge shaft 4 is mounted on the mounting plate 9, and the mounting plate 9 is fixed on an electric vehicle. Below the hinge shaft 4: a limiting notch 601 is formed in the rear side of the large arm 6, a limiting column 5 is fixedly mounted on the inner side of the mounting bent plate 3, the limiting column 5 is matched with the limiting notch 601, and the lower end of the large arm 6 is hinged to the lower end of a small arm 7; the inner sides of the two mounting plates 9 are respectively hinged with two movable arms 11, the two mounting plates 9 are provided with four movable arms 11, the two movable arms 11 on each mounting plate 9 form two opposite parallel edges of a parallelogram, and the upper ends of the four movable arms 11 are hinged on the lower surface of the seat 1; the middle part of a movable arm 11 at the rear part of each mounting plate 9 is fixedly provided with a hinge shaft 10, and the upper end of the small arm 7 is hinged on the hinge shaft 10. A return spring 13 is further installed on the hinge shaft 10, a lower end of the return spring 13 is installed on an ear plate 12, the ear plate 12 integrally extends from a lower end of the mounting plate 9, and the ear plate 12 is located behind and below a hinge point of the movable arm 11 on the rear side and the mounting plate 9.

Between the large arm 6 and the mounting plate 9 there are mounted locking means, which have two embodiments: first, there is a pin hole 602 on the large arm 6, the pin hole 602 is located on the extension line of the large arm 6, a spring lock pin 8 is installed on the corresponding position of the installation plate 9, the spring lock pin 8 includes: the outer end of the pull pin 801 is provided with a ring 803, a hole is drilled in the mounting plate 9, the pin hole 602 can coincide with the hole in the rotation process of the large arm 6, the pull pin 801 can be inserted into the hole and the pin hole 602, then a return spring 802 is sleeved outside the pull pin 801, two ends of the return spring 802 are respectively fixed on the mounting plate 9 and the pull pin 801, the large arm 6 is further provided with a limiting block 603, the limiting block 603 is positioned between the large arm 6 and the small arm 7, and one end of the limiting block 603, which is far away from the large arm 6, can be made into an inclined surface. Secondly, the spring lock pin 8 and the pin hole 602 are the same, except that the spring lock pin 8 is installed inside the large arm 6, the pin hole 602 is opened on the installation plate, the outer end of the pull pin 801 is not provided with a ring and is connected with a brake cable 804, meanwhile, a bending plate 805 is installed inside the large arm 6, the brake cable 804 is installed on the bending plate 805, the brake cables on the two large arms 6 are installed together on a wiring board 806, and the wiring board 806 can be installed on the electric vehicle; when the locking device is used in the second embodiment, there is no stop block 603 between the large arm 6 and the small arm 7.

Because a certain distance exists between the rear end of the seat 1 and the lower end of the backrest 2 in the using process, the distance is the distance of the seat moving backwards after descending, the distance exposes the inside of the electric vehicle to the outside, and the electric vehicle is not attractive, one end of the shielding flexible object 14 is connected to the rear end of the seat 1, and the shielding flexible object 14 can have certain hardness, for example, a piece of leather is folded in half to be suspended; of course, there may be no stiffness, and it is desirable to fixedly attach the two ends of the flexible covering 14 to the seat 1 and the backrest 2, respectively.

When the utility model is used as a driver seat, the pull pin 801 of the spring lock pin 8 is inserted into the pin hole 601 on the big arm 6, and the position of the pull pin 801 on the mounting plate 9 is fixed, so the big arm 6 does not rotate any more, the big arm 6 is fixed, then under the combined action of the hinge shaft 4, the limit post 5 and the limit notch 601, the backrest 2 can only move forwards and can not move backwards, and the backrest 2 slightly tilts backwards, so the position of the backrest 2 is relatively fixed. For the small arm 7, on one hand, the return spring 13 pulls the movable arm 11 downwards and backwards, on the other hand, the limit block 603 limits the backward rotation of the small arm 7, so the position of the small arm 7 is fixed, the middle position of the movable arm 11 at the rear side is fixed, as the lower end of the movable arm 11 is hinged on the mounting plate 9, the movable arm 11 is fixed at two points, the whole movable arm 11 is fixed (two points determine a line), the movable arm 11 at the front side is parallel to the movable arm 11 at the rear side, the upper ends of the movable arm 11 at the front side are hinged on the seat 1, and the lower ends of the movable arm 11 at the front side are hinged on the mounting plate 9, so the movable arm 11 at the front side is also fixed, and the seat 1 is also fixed.

When needing to fall back 2, outwards extract and draw round pin 801, big arm 6 loses control, at this moment return spring 13 begins to play a role, two digging arms 11 backward move under return spring 13's effect, seat 2 descends simultaneously, loosen and draw round pin 801, draw round pin 801 inner to lean on forearm 7, forearm 7 upper end is along with digging arm 11 down, backward movement, thereby it rotates around hinge 4 to drive big arm 6, spacing breach 601 on the big arm 6 promotes spacing post 5 and rotates, thereby make back 2 around hinge 4 forward rotations, finally on the flat seat 1 of putting, so the utility model discloses just folding finishing, the back seat can be pushed forward.

When backrest 2 will be opened, directly lift backrest 2, spacing post 5 leans on spacing breach 601 on promote big arm 6 rotatory, it upwards to drive 7 upper ends of forearm simultaneously, move forward, the angle of V word can grow a bit this moment, when drawing round pin 801 to contact stopper 603, if stopper 603 is normal terminal surface, also be the plane, at this moment, only need manually to pull out draw round pin 801, make draw round pin 801 cross stopper 603 loose hand again can, if be an inclined plane, this inclined plane can be automatic will draw round pin 801 outwards to push up, make draw round pin 801 cross stopper 601 (stopper and big arm are coplanar, draw the round pin just can cross stopper entering pinhole like this, under above-mentioned two kinds of circumstances, finally draw round pin 801 all can be under return spring 802's effect, insert pinhole 602, whole structure is fixed, the utility model discloses just good support.

If the locking means is the second embodiment, it is only necessary to pull the brake cable to move the pulling pin 801 away from the mounting plate 9 when opening and folding the backrest 2.

Other technical features than those described in the specification are known to those skilled in the art.
