Abstract
The utility model discloses an eccentric type damping device of a cart. The eccentric type damping device of the cart comprises a frame and wheels which are arranged on the lower portion of the frame. The frame and the wheels are connected through a cantilever damping mechanism. The cantilever damping mechanism comprises a first cantilever, a damping spring and a second cantilever, wherein the lower end of the first cantilever is connected with the wheels through a center rotating shaft in a shaft mode, and the second cantilever is connected with the frame. The upper end of the first cantilever is in shaft connection with the left end of the second cantilever through a connecting shaft to form a bending structure which can rotate along the connecting shaft. One end of the damping spring is connected to the right end of the second cantilever, and the other end of the damping spring is connected to the lower end of the first cantilever. According to the eccentric type damping device, the vibration of the frame which is connected with the upper side of the second cantilever through the cantilever damping mechanism is obviously weakened by a large margin, after force is decomposed basically, an infant in a stroller can not feel bumping of a road face, the best damping effect is achieved, and the riding comfortableness of the infant is greatly improved. The structure is simple, and mounting is convenient.
Description
Technical field
The utility model relates to a kind of go-cart centering type shock absorption device.
Background technology
Doll carriage is a kind of very common child utensil, can carry the baby to outdoor activities, and it generally includes vehicle frame and wheel, and vehicle frame is arranged on wheel by leg.Existing doll carriage, leg are directly to be contained on the wheel shaft of wheel, with a plurality of point of connection and wheel shaft, fix, and this structure does not have shock-absorbing function, and vehicle frame is directly passed in the vibrations on ground, can make baby wherein that sense of discomfort is arranged.Although some is with shockproof mechanism, that shockproof mechanism is arranged in wheel fork, when wheel at rough road traveling and during vertical tremor, shockproof mechanism can be converted to the vibrations of wheel the elastic potential energy of self, but the complex structure of this shockproof mechanism, trouble is installed, and damping effect is poor.
The utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of go-cart centering type shock absorption device.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of go-cart centering type shock absorption device, comprise vehicle frame and the wheel that is arranged at described vehicle frame bottom, it is characterized in that: between described vehicle frame and wheel, by the cantilever damping, connect; Described cantilever damping comprises the first cantilever, the damping spring that lower end and wheel are connected by the central rotating shaft axle and the second cantilever that is connected with vehicle frame, and the left end of the upper end of described the first cantilever and the second cantilever is connected to form by the adapter shaft axle can be along the bending structure of adapter shaft rotation; Described damping spring one end connects the right-hand member of the second cantilever, and the other end connects the lower end of the first cantilever.
Described go-cart centering type shock absorption device is characterized in that: described the first cantilever, the second cantilever and damping spring are connected to form triangular structure.
Described go-cart centering type shock absorption device, it is characterized in that: described damping spring vertically arranges.
As preferred version, described go-cart centering type shock absorption device is characterized in that: described the first cantilever becomes the setting of 50-100 degree angle with the second cantilever.
Beneficial effect: the go-cart centering type shock absorption device that the utility model provides, the vibrations of wheel pass to the first cantilever and damping spring by central rotating shaft, vibrations are converted to the elastic potential energy of self through damping spring, make the first cantilever and the second cantilever angle produce trickle variation along adapter shaft, the seismaesthesia of the vehicle frame that is connected with the second cantilever upside obviously significantly weakens, after being decomposed substantially, power makes the jolting of the imperceptible road surface of baby in perambulator, it is best that damping effect reaches, and greatly improved the comfort level that the baby takes; And simple in structure, easy for installation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of go-cart centering type shock absorption device, comprise vehicle frame 1 and the wheel 2 that is arranged at described vehicle frame 1 bottom, between described vehicle frame 1 and wheel 2, by cantilever damping 3, connects; Described cantilever damping 3 comprises the first cantilever 5, the damping spring 7 that lower end and wheel 2 are connected by central rotating shaft 4 axles and the second cantilever 6 that is connected with vehicle frame 1, and the left end of the upper end of described the first cantilever 5 and the second cantilever 6 is connected to form by adapter shaft 8 axles can be along the bending structure of adapter shaft 8 rotations; Described damping spring 7 one ends connect the right-hand member of the second cantilever 6, and the other end connects the lower end of the first cantilever 5.Described the first cantilever 5, the second cantilever 6 and damping spring 7 are connected to form triangular structure.Described damping spring 7 vertically arranges.6 one-tenth 50-100 degree angles of described the first cantilever 5 and the second cantilever arrange.
The go-cart centering type shock absorption device that the utility model provides, the vibrations of wheel pass to the first cantilever and damping spring by central rotating shaft, vibrations are converted to the elastic potential energy of self through damping spring, make the first cantilever and the second cantilever angle produce trickle variation along adapter shaft, the seismaesthesia of the vehicle frame that is connected with the second cantilever upside obviously significantly weakens, after being decomposed substantially, power makes the jolting of the imperceptible road surface of baby in perambulator, it is best that damping effect reaches, and greatly improved the comfort level that the baby takes; And simple in structure, easy for installation.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
