Description
The utility model relates to a kind of folding device of car, refer to especially a kind of amount to, launch the operation simple and easy, the folding device of car safe to use.
Along with the increase of leisure time, the outdoor leisure activity is universal day by day, and various suitable outdoor exercises such as bicycle, Kickboard Scooter etc. rise thereupon, are subjected to many people's favor at short notice.For adapting to the road conditions of different places such as each corner, city and country, make stress-relieving activity more humane, this series products must have the Portability of most convenient, allows people can be carried to different destinations easily, and can minimizing take up room when collection.For addressing this need, a kind of bicycle folding structure is arranged at present on the market, as shown in Figure 6, it is before vehicle frame, set firmly riveted plate 30 and riveted joint plate 20 on the back segment section respectively, riveted plate 30 and 2 of plates of riveted joint articulate with rivet 40, make both be able to freely rotate, the opposite side of riveted joint plate 20 is established a pin riveting pipe 22 of rolling, the stage casing of this pin riveting pipe 22 is provided with a breach, a ccontaining packing stick 60 in the breach, one latch 50 is arranged in the pin riveting pipe 22 and packing stick 60 of riveted joint plate 20, and the eccentric path that makes latch 50 stage casings is placed in the perforation 62 of packing stick 60,50 one-tenth vertical configurations of packing stick 60 and latch, the terminal spiral shell of packing stick 60 is established the surface that a clamp holder 61 is butted on riveted plate 30, make latch 50 rotation and make packing stick 60 produce skew, and will rivet plate 20 and riveted plate 30 urgent combinations, to reach the purpose that the vehicle frame expansion is fixed by the eccentric path in latch 50 stage casings.
Though above structure can reach when using the purpose of launching, amounting to when collecting, can produce the not good problem of safety when driving when using.Above-mentioned vehicle body foldable structure only utilizes the eccentric position interlock on the latch to chase after the purpose that tight bar reaches the expansion use, there is no the design of any location, if produce stronger vibrations through bumpy sections when event drives, latch will be got loose cause user's life danger; In addition, when the rider wore looser clothing, clothing easily was hooked in its generation rotation is got loose, and causes danger; Moreover spiral shell is located at clamp holder on the packing stick also easily because of vibrations get loose, and causes danger.So planting the safety in utilization of commonly using structure makes us causing anxiety.
In sum, commonly use product can't be shown consideration for the rider fully when launch using safety, in view of this, the folding device of the car of safety when main purpose of the present utility model provides simple and easy, the effective raising of an operation and drives.
For finishing above-mentioned purpose, the technical scheme of the folding device of the utility model car is: its forward and backward vehicle frame section part is installed with riveted plate and riveted joint plate, and articulates combination at homonymy with axle, and the riveted plate all is shelly with the riveted joint plate, and both openings are relative; The riveted plate is pivoted with first rotating shaft and second rotating shaft with the appropriate location of riveted joint plate, the upper end of this first rotating shaft connects a drive spindle, the other end of this drive spindle is pivoted with the 3rd rotating shaft, the relative position of this drive spindle and second rotating shaft is provided with the short slot that makes second rotating shaft ccontaining, described second and third rotating shaft connects with a connecting rod, and back vehicle frame appropriate location is provided with the pin of the side that is butted on described drive spindle.Form three bar linkage structures relation by above assembly, when desiring to make vehicle frame to amount to, as long as what the promotion drive spindle made is that rotate in the axle center with first rotating shaft, make the line of the first, the 3rd rotating shaft cross the position of second rotating shaft, vehicle frame is amounted to smoothly, because the user need only do the action of pulling drive spindle when amounting to, so effectively improved the vehicle frame expansion, amount to the simplification of action.
Described pin is butted on drive spindle when vehicle frame launches, make its strong fix, gets loose when effectively avoiding drive spindle to use and causes danger, so can effectively improve the safety of use.
Described connecting rod combines with riveted joint with second rotating shaft, and this connecting rod back segment is provided with the thread segment that screws togather with the 3rd rotating shaft, and the end of this connecting rod is provided with the short slot of the distance of fine-tuning second and third rotating shaft.Suitably the adjusting shaft spacing front and back wheel coplane radially that can make car effectively reduces riding resistance.
Described the 3rd rotating shaft upper end drive spindle is provided with a push button that the preferable point of application arranged when allowing the user pull the button drive spindle outward, and this push button can make the more laborsaving and safety of operation.
The relative position of described riveted plate and riveted joint plate can be respectively equipped with chimeric trapezoidal projection and trapezoidal groove mutually, makes butt joint more firm.
Below in conjunction with accompanying drawing the utility model is further described.
