Technical Field

[0001] The utility model relates to the technical field of electric baby carriages, in particular to an electric baby carriage with a wheel hub that is convenient to install. Background Art

[0002] Children's cars are a major category of children's toys, which include five categories: children's bicycles, children's strollers, baby walkers, children's tricycles, and children's electric cars. Electric cars are a toy that is very popular among children. Children can sit in them and operate the electric cars, including starting, braking, steering, etc. Children can also sit in them and adults can operate them through remote controls. Currently, electric cars are all rear-wheel drive, and the front axle is only responsible for steering.

[0003] The installation shaft of the children's tricycle helps connect the two rear wheels together, transmits the power of the motor to the rear wheels, allows the rear wheels to rotate, and allows the children's tricycle to move forward. At the same time, the installation shaft also plays a supporting role on the frame.

[0004] When installing a common mounting shaft on a frame, other fixing parts are required to fix the connecting part between the mounting shaft and the frame to the mounting shaft, otherwise the mounting shaft will slide left and right inside the connecting part. However, such fixing parts require additional manufacturing costs. In view of this, the present application proposes an electric children's vehicle that is easy to install a wheel hub. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an electric children's stroller that is easy to install a wheel hub and has advantages such as a segmented mounting shaft. It solves the problem that when the mounting shaft is installed on the frame, other fixing parts are needed to fix the connecting part between the mounting shaft and the frame to the mounting shaft, which increases the manufacturing cost.

[0006] In order to achieve the above-mentioned purposes of segmented mounting shafts, the utility model provides the following technical solutions: an electric baby stroller that is convenient for mounting a wheel hub, comprising a frame, two support seats are threadedly mounted on the bottom of the frame through bolts and nuts, a mounting shaft is rotatably mounted between the two support seats, a driven gear is fixedly mounted on the surface of the mounting shaft, wheel hubs are movably mounted on both ends of the mounting shaft, a reinforcing plate is fixedly mounted on the side of the wheel hub that contacts the mounting shaft, the mounting shaft is threadedly connected to the wheel hub through connecting bolts, and a tire is movably mounted on the surface of the wheel hub;

[0007] The support seat includes a mounting plate at the bottom of the frame threadedly mounted by bolts and nuts, a support rod fixedly mounted at the bottom of the mounting plate, a bearing fixedly mounted at the bottom end of the support rod, and a reinforcing rib fixedly mounted at the bottom of the mounting plate with one side welded to the surface of the support rod.

[0008] Furthermore, the installation shaft comprises a thick shaft rotatably installed between the two support seats, and thin shafts are fixedly installed at both ends of the thick shaft, and a threaded hole adapted to the connecting bolt is opened at one end of the thin shaft.

[0009] Furthermore, the thin shaft is rotatably connected to the support rod via a bearing, and the connecting bolt is rotatably passed through the wheel hub and is threadedly connected to the threaded hole.

[0010] Furthermore, a driving motor is fixedly installed at the bottom of the frame and between the two supporting seats, and a driving gear meshing with a driven gear is fixedly installed at the output end of the driving motor.

[0011] Furthermore, a battery compartment is fixedly installed on the top of the frame, and a seat cushion is fixedly installed on the top of the battery compartment.

[0012] Furthermore, a connecting sleeve is fixedly installed on the top of the frame, a steering column is rotatably installed inside the connecting sleeve, a handle is fixedly installed on the top of the steering column, a rotating bracket is fixedly installed on the bottom of the steering column, and a steering wheel is rotatably installed on the bottom of the rotating bracket.

[0013] Compared with the prior art, the utility model provides an electric baby carriage that is easy to install a wheel hub, and has the following beneficial effects:

[0014] The electric baby stroller with easy wheel hub installation divides the installation shaft into a thick shaft and a thin shaft, so that the support seat can be clamped on the surface of the installation shaft without other fixing parts, thereby solving the problem of increased manufacturing cost caused by the need to use other fixing parts to fix the connecting part between the installation shaft and the frame to the installation shaft when the installation shaft is installed on the frame. One side of the support seat contacts one end of the thick shaft and is then threadedly connected to the top of the frame, so that the two support seats will not slide on the installation shaft, and the cost of additional fixing parts is saved.
