Abstract
The utility model discloses a bicycle damping backseat which consists of a seat rack, a supporting rack, and a connecting rack, which forms a stable triangle structure. The supporting rack is supported on two ends of the bicycle rear axle, and the connecting rack is connected with the bicycle rack. The supporting rack comprises the supporting rod on two ends of the bicycle rear axle, a supporting sheath and a buffer spring arranged on the supporting rod. The buffer spring is positioned inside the supporting sheath and on the top of the supporting rod. The top of the connecting rack is arranged with a sleeve and the corresponding place of the bicycle is arranged with the U shaped trench of the sleeve which is hinged and connected with the U shaped trench. When the vibration occurs, the vibration on the backseat of the bicycle is relieved due to the damping function of the spring. The backseat is mainly used on the bicycle or the electric bicycle.
Description
[technical field]
The utility model relates to bicycle, especially relates to a kind of damping bicycle back seat.
[background technology]
At present, existing manpower or Electrical Bicycle, its back seat generally all is rigidly connected, there is not shock absorption device, when children ride on the back seat or carry the article frangible, that fearness shakes,, can produce big bump in the travels down of injustice, the people is felt very ill, perhaps cause article to damage.Though someone installs sponge on back seat, play certain cushioning effect, then can not tackle the problem at its root for potholed road.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of damping bicycle back seat, alleviates the vibrations that bicycle jolts and produces.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of damping bicycle back seat is provided, comprise mounting, bracing frame and link span, mounting, bracing frame and link span constitute stable triangular structure, bracing frame is supported on the two ends of back wheels of vehicle axle, link span connects vehicle frame, described bracing frame is made up of the strut bar that is supported on back wheels of vehicle axle two ends, the support sleeve that is sheathed on strut bar and damping spring, and described damping spring is placed in the support sleeve and the strut bar end is located on the top; The end of described link span is provided with a sleeve respectively, and " U " type groove that relative set can ccontaining this sleeve on the vehicle frame, sleeve pivot with " U " type groove and be connected.
Further improvement in the technical proposal is:
In described support sleeve, the two ends of damping spring are provided with a spring mountings respectively, spring mountings has the outshot that stretches into the spring endoporus, spring mountings can slide along the support sleeve inwall.
A sheathed jam nut on the described strut bar, jam nut is connected with the support sleeve inner hole thread; In strut bar and the jam nut diameter clearance sliding sleeve is set, the sliding sleeve nut locking that is locked, and strut bar can be free to slide along the sliding sleeve endoporus; There is the boss of a diameter greater than the sliding sleeve diameter of bore described strut bar end.
Described spring mountings respectively has a groove, and described groove is buckled in the fixed end in strut bar end and the support sleeve respectively.
The two ends of described sleeve fixedly install an axle sleeve respectively.
Described spring mountings, sliding sleeve, axle sleeve are made by plastic cement.
The beneficial effects of the utility model are: because the bracing frame of the utility model damping bicycle back seat is made up of the strut bar that is supported on back wheels of vehicle axle two ends, the support sleeve that is sheathed on strut bar and damping spring, damping spring is placed in the support sleeve and the strut bar end is located on the top, so bracing frame is a kind of elastic rod, when producing vibrations, because the cushioning effect of spring alleviates the vibrations of rear bicycle.When vibrations took place, spring was compressed, and mounting can be rotated down mobile, is pivotable between link span and the bicycle, and mounting can be rotated freely.

Below in conjunction with accompanying drawing the utility model is described further:
[specific embodiment]
See also Fig. 1 to Fig. 5:
The utility model damping bicycle back seat comprises mounting 1, bracing frame 2 and link span 3, and mounting 1, bracing frame 2 and link span 3 constitute stable triangular structure, and bracing frame 2 is supported on the two ends of the axle 10 of back wheels of vehicle 9.The end of link span 3 is provided with a sleeve 5 respectively, " U " type groove 6 that relative set can ccontaining this sleeve on the vehicle frame 4, and sleeve 5 pivots and is connected by bolt 7, nut 8 with " U " type groove 6, and link span 3 and vehicle frame 4 are linked together.
Figure 4 shows that support frame structure figure, bracing frame 2 is made up of strut bar 21, the support sleeve 22 that is sheathed on strut bar 21 and the damping spring 23 at axle 10 two ends that are supported on back wheels of vehicle 9, and described damping spring placement 23 is also pushed up in support sleeve 22 and is located at strut bar 21 ends; In support sleeve 22, the two ends of damping spring 23 are provided with a spring mountings (24,25) respectively, spring mountings (24,25) has the outshot (241,251) that stretches into damping spring 23 endoporus, it is spacing for damping spring 23 working, and spring mountings (24,25) slides along support sleeve 22 inwalls.
A sheathed jam nut 27 on the strut bar 21, jam nut 27 is connected with support sleeve 22 inner hole threads; In strut bar 21 and jam nut 27 diameter clearances sliding sleeve 26 is set, sliding sleeve 26 nut 27 lockings that are locked, and strut bar 21 can be free to slide along sliding sleeve 26 endoporus; The boss 211 of one diameter greater than sliding sleeve 26 diameter of bores arranged in strut bar 21 ends, and its effect is to prevent that strut bar 21 from skidding off.
Spring mountings (24,25) respectively has a groove (242,252), and described groove (242,252) is buckled in the fixed end 221 in strut bar end boss 211 and the support sleeve 22 respectively.
