Description

Technical Field

[0001] The invention relates to the technical field of electric baby carriages, and in particular to a quick-release installation structure for a steering wheel of an electric baby carriage. Background Art

[0002] ‌An electric baby stroller is a toy car for children to drive. It is motor-driven and safe to operate. It allows children to drive by themselves and supports parent-child interaction. It is a novel children's toy. The main functions of an electric baby stroller include simulated driving experience. It usually comes with a remote control for easy parental control. The vehicle design takes children's safety into consideration and usually has an enclosed seat to prevent children from falling off the vehicle. Electric strollers can be controlled not only by remote controls but also by steering wheels. Electric strollers need to be played with by parents. It is dangerous for children to operate electric strollers by themselves. Remote control can be used to prevent children from operating the stroller alone. However, electric strollers with steering wheels are difficult to prevent children from operating the stroller by themselves. The steering wheels in electric strollers are generally fixed directly at the steering connection. After starting the electric stroller, children can directly control its movement, which means that children can operate the electric stroller alone without the supervision of their parents.

[0009] Furthermore, the top of the force-bearing frame contacts the bottom of the extrusion rod, and the number of the bent plates is four, and the four bent plates are arranged in a circle with the force-bearing frame as the center.

[0010] Further, the extrusion component comprises a linkage plate, the end of the linkage plate is fixedly connected to the surface of the support ring, one end of the linkage plate away from the support ring is fixedly connected to a sliding ring, and the bottom of the inner wall of the positioning groove is fixedly connected to an elastic sheet; A pressing block is fixedly connected to one end of the elastic sheet away from the positioning groove, and a limiting ring is fixedly connected to the lower surface of the sliding rod.

[0012] The present invention has the following beneficial effects: The present invention requires that when the steering wheel is installed, the sleeve rod is directly sleeved on the surface of the insertion rod, and the plug-in component inside the sleeve rod will be inserted into the inside of the cross groove, and the sleeve rod is limited by the connection between the cross groove and the plug-in component, so that when the steering wheel twists the sleeve rod to rotate, the sleeve rod can be twisted through the connection between the plug-in component and the cross groove to rotate the insertion rod and the steering rod, thereby controlling the direction of the electric baby stroller, improving the convenience of the steering wheel during installation, and squeezing the fixing component to shrink when the plug-in component is inserted into the inside of the cross groove, and the fixing component will be stuck on the surface of the sleeve rod when shrinking, fixing the sleeve rod, and improving the stability of the sleeve rod after installation. The squeezing component is located at the lower surface of the sliding rod, and when the plug-in component squeezes the fixing component, the squeezing component will squeeze the fixing component, so that the fixing component can quickly shrink to install and fix the sleeve rod, and after the fixing component slides downward, the fixing component can quickly expand and separate from the sleeve rod, so as to disassemble the steering wheel.

[0013] After the steering wheel of the present invention is sleeved on the surface of the insertion rod through the sleeve rod, the cross rod will be inserted into the inner center of the cross groove, and at the same time, the extension plate will limit the sleeve rod as the cross rod is inserted into the inside of the cross groove.

[0014] After the cross rod of the present invention is inserted into the interior of the cross groove, the extrusion rod will enter the interior of the cylindrical hole through the connecting hole and contact the top of the force-bearing frame, and squeeze the force-bearing frame to slide downward. When the force-bearing frame moves, it pushes the bent plate to move downward through the positioning plate. When the bent plate moves downward, it will contact the extrusion component. The extrusion component is used to squeeze the bent plate to shrink toward the surface of the sleeve rod. When the bent plate shrinks, it pushes the arc plate to contact the inner wall of the annular groove. The sleeve rod is fixed to the surface of the insertion rod by the arc plate to prevent the steering wheel from falling off after installation.

[0015] When the bent plate of the present invention moves downward, it will contact the surface of the adapter plate, and the adapter plate is used to push the top of the bent plate to shrink toward the surface of the sleeve rod to fix the sleeve rod. When the steering wheel needs to be disassembled, the pressing block is pushed to slide toward the inside of the positioning hole, so that the pressing block is separated from the bottom of the sliding ring. At this time, the sliding ring can push the support ring to move downward through the linkage plate. When the support ring moves downward, it pushes the adapter plate to separate from the surface of the bent plate through the right-angle plate. After the bent plate is separated from the adapter plate, the elasticity of the elastic sheet is used to push the arc plate to separate from the inner wall of the circular ring groove, so that the sleeve rod can be quickly separated from the insertion rod to disassemble the steering wheel.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
