Technical Field

[0001] This utility model relates to the field of children's vehicle technology, and more specifically, it relates to a children's vehicle steering wheel that is easy to disassemble and assemble. Background Technology

[0002] Children's vehicles are toy cars that children can drive and sit in. Currently, the main types of children's electric vehicles on the market are: cars, motorcycles, and construction vehicles. The appearance of various children's vehicles is basically similar to that of various motor vehicles.

[0003] Existing quick-release steering wheels for children's cars typically involve inserting the steering wheel through a hole into the end of the shaft, then using bolts to pass through the steering wheel and shaft, and finally tightening the steering wheel and shaft together with nuts. This method of installing steering wheels is very cumbersome and inconvenient for quick disassembly and installation.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a child car steering wheel that is easy to disassemble and assemble.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a child stroller steering wheel that is easy to disassemble and assemble, comprising a steering wheel and a steering shaft. The steering wheel includes a disc body and a connecting sleeve disposed at the bottom of the disc body. A positioning component for detachably connecting to the steering shaft is disposed inside the connecting sleeve. The positioning component includes a positioning rod disposed on the periphery of the steering shaft. An annular groove is formed on the circumferential surface of the steering shaft. An arc-shaped groove conforming to the inner wall of the annular groove is provided at the end of the positioning rod. The steering component also includes a driving component for controlling the positioning rod to move towards or away from the steering shaft.

[0007] The present invention is further configured such that: a connecting block is provided inside the connecting sleeve, a through hole is provided in the middle of the connecting block for the steering shaft to pass through, the diameter of the through hole is equal to the diameter of the steering shaft, a connecting rod is provided on the periphery of the connecting block, and a sliding groove is provided inside the connecting rod along its length for the positioning rod to slide and connect, one end of the sliding groove is connected to the through hole.

[0008] The present invention is further configured such that: the driving component includes a spring disposed on the inner wall of the sliding groove end and the end of the positioning rod; the bottom of the connecting rod is provided with a guide groove communicating with the sliding groove along its length direction; the bottom of the positioning rod is provided with a guide rod sliding in the guide groove; the connecting block is rotatably connected to the connecting sleeve with the steering shaft as the center; a fixing ring is fixedly connected to the connecting sleeve below the connecting block; the surface of the fixing ring is provided with a plurality of abutment plates corresponding to the guide rod; the abutment plates are inclined at a certain angle to the guide groove; by rotating the connecting block and the connecting rod, the abutment plates push the guide rod to slide along the guide groove toward one end of the spring.

[0009] The present invention is further configured such that: the inner wall of the connecting sleeve is provided with an annular groove along its circumference, and the end of the connecting rod is provided with an arc surface that fits into the annular groove.

[0010] The present invention is further configured such that: the end of one of the connecting rods extends out of the outer surface of the connecting sleeve, and a sliding groove for horizontal rotation is provided on one side of the connecting sleeve.

[0011] The present invention is further configured such that: the inner wall of the end of the sliding groove and one end of the positioning rod are provided with a sleeve rod for the spring to be sleeved.

[0012] This invention has the following advantages: When installing the steering wheel of the children's vehicle, simply insert the steering shaft into the connecting sleeve, and the drive unit will move the positioning rod toward the steering shaft, embedding its end into the annular groove. The inner wall of the arc-shaped groove will then fit against the inner wall surface of the annular groove, thereby restricting the vertical movement of the steering rod while ensuring its smooth rotation in the horizontal direction. When disassembly is required, the drive unit will move the positioning rod away from the steering shaft, separating its end from the annular groove, thus allowing the steering wheel to be disassembled from the steering shaft. This facilitates the disassembly and assembly of the children's vehicle's steering wheel. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0017] As shown in the figure, a child stroller steering wheel that is easy to assemble and disassemble includes a steering wheel 1 and a steering shaft 2. The steering wheel includes a disc body 3 and a connecting sleeve 4 disposed at the bottom of the disc body 3. The connecting sleeve 4 is provided with a positioning component for detachable connection to the steering shaft 2. The positioning component includes a positioning rod 5 disposed on the periphery of the steering shaft. An annular groove 6 is formed on the circumferential surface of the steering shaft 2. The end of the positioning rod 5 is provided with an arc-shaped groove 7 that fits into the inner wall of the annular groove 6. The steering wheel also includes a drive component for controlling the positioning rod 5 to move towards or away from the steering shaft 2.

[0018] When installing the steering wheel of the children's stroller, simply insert the steering shaft 2 into the connecting sleeve 4. The drive unit moves the positioning rod 5 toward the steering shaft 2, causing its end to embed into the annular groove 6. This allows the inner wall of the arc-shaped groove 7 to fit against the inner wall surface of the annular groove 6. This restricts the vertical movement of the steering rod while ensuring smooth rotation of the steering rod in the horizontal direction. When disassembly is required, the drive unit moves the positioning rod 5 away from the steering shaft 2, causing its end to separate from the annular groove 6. This allows the steering wheel to be disassembled from the steering shaft 2, making it easy to install and remove the steering wheel of the children's stroller.

[0019] The connecting sleeve 4 has a connecting block 8 inside. The connecting block 8 has a through hole 9 in the middle for the steering shaft 2 to pass through. The diameter of the through hole 9 is equal to the diameter of the steering shaft 2 to improve the stability of the steering shaft 2 after installation. The connecting block 8 has a connecting rod 10 on its periphery. The connecting rod 10 has a sliding groove 11 inside along its length for the positioning rod 5 to slide. One end of the sliding groove 11 is connected to the through hole 9, making its internal structure compact and ensuring the accuracy of the movement of the positioning rod 5.

[0020] The driving component includes a spring 12 disposed on the inner wall of the end of the sliding groove 11 and the end of the positioning rod 5. A sleeve rod 13 for the spring 12 is disposed on the inner wall of the end of the sliding groove 11 and one end of the positioning rod 5. A guide groove 14 communicating with the sliding groove 11 is opened at the bottom of the connecting rod 10 along its length direction. A guide rod 15 sliding in the guide groove 14 is disposed at the bottom of the positioning rod. The connecting block 8 is rotatably connected to the connecting sleeve 4 with the steering shaft 2 as the center. A fixing ring 16 is fixedly connected to the connecting sleeve 4 below the connecting block 8. A plurality of abutment plates 17 corresponding to the guide rod 15 are disposed on the surface of the fixing ring 16. The abutment plates 17 are inclined at a certain angle to the guide groove 14. By rotating the connecting block 8 and the connecting rod 10, the abutment plates 17 push the guide rod 15 to slide along the guide groove 14 toward one end of the spring 12.

[0021] Under the action of the spring 12, the end of the positioning rod 5 is always located in the annular groove 6, ensuring the stability of the steering wheel after installation. By rotating the connecting block 8, the inclined abutment plate 17 and the guide rod 15 move relative to each other, converting the rotational motion into the linear motion of the guide rod 15 and the positioning rod 5, thereby overcoming the spring force of the spring 12 and unlocking the steering shaft 2.

[0022] The inner wall of the connecting sleeve 4 has an annular groove along its circumference. The end of the connecting rod 10 is arranged in an arc shape to fit the annular groove 6 and slides within the annular groove. The end of one of the connecting rods 10 extends out of the outer surface of the connecting sleeve 4, and a sliding groove 18 for horizontal rotation is provided on one side of the connecting sleeve 4. The user only needs to move the connecting rod 10 extending out of the outer surface of the connecting sleeve 4 with one hand to rotate the connecting block 8. After releasing the connecting rod 10, the positioning rod 5 is pushed under the elastic force of the spring 12, and the guide rod 15 moves relative to the abutment plate 17, thereby causing the connecting block 8 to rotate and reset.

[0023] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
