The utility model content
The technical problems to be solved in the utility model provides a kind of baby carriage.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of baby carriage, comprise the go-cart vehicle frame, be arranged at the wheel assembly of described go-cart vehicle frame bottom, described wheel assembly comprises the wheel joint that is connected with the bottom of described go-cart vehicle frame, top and the described joint of taking turns are by first rotating shaft bonded assembly erecting frame that rotates, be connected in the wheel of described erecting frame bottom, described first rotating shaft parallels with horizontal surface, the described wheel between joint and the described erecting frame is provided with vibration damping spring, and described vibration damping spring departs from described first rotating shaft.
In some embodiments, described vibration damping spring is a stage clip, and its length is extended along above-below direction.
In some embodiments, to be positioned at the center of rotation with described first rotating shaft be on the circumferencial direction in the center of circle to described vibration damping spring.
In some embodiments, the described joint of taking turns is connected by second rotating shaft rotatedly with described go-cart vehicle frame, and the direction of axis line of described second rotating shaft extends along above-below direction.
In some further embodiment, described first rotating shaft is vertical with the described second rotating shaft phase space.
In some another further embodiment, described second rotating shaft is to be extended upward by described part of taking turns joint to form.
In some embodiments, described wheel assembly is a front component.
Scope of the present utility model is not limited to the technical scheme that the particular combinations of above-mentioned technical characterictic forms, and also should contain simultaneously by above-mentioned technical characterictic or its equivalent feature to carry out combination in any and other technical scheme of forming.The technical characterictic that disclosed (but being not limited to) has a similar functions among for example above-mentioned feature and the application is replaced mutually and technical scheme of forming etc.
Because the technique scheme utilization, the utility model compared with prior art has following advantage: vibration damping spring departs from first rotating shaft, and not fragile, intensity is higher, and shock-proof effect is better.
Description of drawings
Accompanying drawing 1 is a block diagram of the present utility model;
