Abstract
The invention discloses a double-seat folding mechanism. The double-seat folding mechanism comprises a front vehicle frame where a front seat is installed and a back vehicle frame where a back seat is installed. The front vehicle frame is connected with the back vehicle frame through a main four-bar mechanism with a folding pair, the four-bar mechanism is composed of upper connecting bars, a folding pair and lower connecting bars, the upper connecting bars and the front vehicle frame are fixed or integrated, the lower connecting bars and the back vehicle frame are fixed or integrated, a handle is arranged on the front vehicle frame, a rotating fixing plate is connected with the handle, the back vehicle frame is provided with a folding position fixing groove and an unfolding position fixing position groove, and the rotating fixing plate is embedded into the folding position fixing groove or the unfolding position fixing position groove; one end of a back seat connecting bar is hinged to the folding pair of the main four-bar mechanism, the other end of the back seat connecting bar is hinged to one end of an auxiliary four-bar mechanism, and the other end of the auxiliary four-bar mechanism is connected with the back seat. By means of the double-seat folding mechanism, the large folding length is achieved, and therefore a folded vehicle body is smaller and more exquisite and easier to store.
Description
Technical field
The present invention relates to walking-replacing tool field, more particularly, relate to a kind of foldable tandem mechanism.
Background technology
As everyone knows, folding mode that is folding three-wheeled or four-wheel mostly is the folding or screw of the slideway of drawing and pulling type and folds; Slideway has the lap of certain length.Such as, car normal axis is apart from 1 meter, and deduct radius of wheel 0.25 meter, as required folding free length 0.6 meter, then lap only has 0.15 meter, and does not consider the surplus in the actual enforcements such as moulding.
Summary of the invention
Technical matters to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of solution of foldable tandem mechanism.
Foldable tandem mechanism of the present invention, be achieved by following technical proposals, comprise the front vehicle frame of installing front stall and the Rear frame of installing back seat, it is characterized in that, described front vehicle frame is connected with Rear frame by having folding secondary main four-bar linkage, described four-bar linkage is by upper connecting rod, folding secondary and lower link composition, upper connecting rod and front vehicle frame are fixed or one, lower link and Rear frame are fixed or one, remove being arranged at front vehicle frame, rotate adapter plate and remove being connected, Rear frame arranges folding position hold down groove and launches position fixed bit groove, rotate adapter plate to be embedded in folding position hold down groove or to launch in the fixed bit groove of position, the folding pair of back seat link rod one end and main four-bar linkage is hinged, the back seat link rod other end and secondary four-bar linkage one end hinged, the secondary four-bar linkage other end is connected with back seat.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts double leval jib to fold, if long 0.3 meter of folding connecting rod, then actual folding free length can reach 0.5 meter, as added the interlock with back seat, actual folding free length can reach 0.7 meter, present invention achieves longer folded length, make the car body after folding smaller and more exquisite, more easily deposit.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in figs 1-9, comprise the front vehicle frame 2 of installing front stall 1 and the Rear frame 4 of installing back seat 3, front vehicle frame is connected with Rear frame by having the folding four-bar linkage of secondary 5, four-bar linkage is made up of upper connecting rod, folding pair and lower link, upper connecting rod and front vehicle frame are fixed or one, lower link and Rear frame are fixed or one, remove and be arranged at front vehicle frame 6, rotate adapter plate 7 and remove being connected, Rear frame arranges folding position hold down groove 9 and launches position fixed bit groove 10, rotates adapter plate and is embedded in folding position hold down groove or launches in the fixed bit groove of position; The folding pair of back seat link rod 8 one end and main four-bar linkage is hinged, the back seat link rod other end and secondary four-bar linkage one end hinged, the secondary four-bar linkage other end is connected with back seat.
Mechanism by being responsible for main four-bar linkage that front/rear frame folds, the link rod being responsible for four-bar linkage that back seat folds, being responsible for the connecting rod mechanism fixed front/rear frame folding position and bridge joint two four-bar linkages thus realizing interlock forms.Rotate adapter plate and remove being connected, move handle, rotate adapter plate and throw off folding position hold down groove, front vehicle frame realizes folding to Rear frame direction by having folding secondary four-bar linkage, the four-bar linkage that Rear frame is connected by back seat simultaneously realizes folding to front vehicle frame direction, and now car body is folding puts in place, unclamps and removes handle, rotate adapter plate and insert expansion position fixed bit groove, realize fixing.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
