Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

The electric motor car tailstock of prior art is fixed, not adjustable use form, and it includes integrated into one piece's tailstock and back support usually, or add the form of back support at the tailstock rear portion, through dismantling the back packing box or the back tailstock of former car, reaches the needs of addding 10 lengths of cushion after installing additional.

As shown in fig. 1 to 6, the utility model provides a pair of adjustable electric motor car tailstock extension frame, including tailstock extension frame 1 and back support frame 2, the both sides of tailstock extension frame 1 have spout 3, and back support frame 2 includes its body and a pair of spoke 4 that is located both sides, and spoke 4 slides through guide 5 and sets up in spout 3 and carries out the locking through locking piece 6 to sliding motion.

In some embodiments, the surfaces of the tailstock extension stand 1 and the back support stand 2 are provided with a plurality of mounting holes 7, and the mounting holes 7 are used for establishing mounting bases on the two mounting planes so as to adapt to different supporting seats 8 or back support parts.

In some embodiments, the front portion of the tailstock extension frame 1 is fixedly provided with a supporting seat 8, both sides of the supporting seat 8 are provided with kidney-shaped holes 9, a cushion 10 is arranged above the supporting seat 8, the cushion 10 is fixed in the kidney-shaped holes 9 through fixing members 11, and the fixing members 11 are preferably bolts and nuts, so as to be detachable.

In particular, the outer diameters of both sides of the seat cushion 10 are smaller than the inner diameter of the back support frame 2, so that the outer contour thereof can be accommodated in the accommodating space formed inside the back support frame 2.

In some embodiments, the locking member 6 is a quick buckle, the quick buckle is disposed between the spoke 4 and the sliding groove 3, and the user can manually adjust the front and back relative positions of the back support frame 2 through the quick buckle, and when the user specifically operates, the quick buckle is pulled to release the pressure, so that the spoke 4 can freely slide in the sliding groove 3, and after the front and back positions are adjusted, the locking is realized by pressing the quick buckle to apply the pressure to the joint.

In some embodiments, the guiding element 5 is a bolt and a nut, i.e. the lower part of the spoke 4 has three round holes, the middle part is used for installing the quick buckle, the two sides are the installation positions of the guiding element 5, the bolt guides the spoke 4 into the sliding groove 3 in a sliding manner through the round holes, and the other side of the bolt is provided with the nut and the anti-slip gasket, so that the bolt is movably fixed.

The present embodiment has two different use states:

as shown in fig. 1-4, the utility model is in a use state when a person sits on the seat, that is, the back support frame 2 is in a spatial overlapping state with respect to the tailstock extension frame 1, in other words, the outer diameters of the two sides of the tailstock extension frame 1 are smaller than the inner diameter of the back support frame 2, so that the tailstock extension frame 1 can be accommodated inside the tailstock extension frame; with the advantages, the cargo box or the back supporting part and other back supporting type back supporting parts can be arranged above the back supporting frame 2, so that the back supporting parts of the rider can not be arranged due to the lengthening of the existing cushion 10 in the front-back axial direction of the vehicle body in the single-person driving process, and the driving experience is better and safer.
