Description

Technical Field

[0001] This utility model relates to the field of children's vehicle technology, and in particular to a quick-release installation structure for an electric children's vehicle steering wheel. Background Technology

[0002] As a common means of entertainment and transportation for children, the steering wheel of an electric stroller is the core component for overall vehicle control. It not only integrates control buttons for functions such as horn and music playback, but also connects to the vehicle's drive system via internal circuitry to achieve steering control. To ensure the safety of children and the integrity of its functions, the steering wheel must be securely connected to the steering shaft, and its internal electrical connections must be accurate and reliable.

[0003] However, the existing installation structure of children's stroller steering wheels has significant flaws. For mechanical connections, the common method involves aligning the steering wheel base's mounting holes with the steering shaft, inserting the wheel, then using bolts to thread laterally through the base and shaft, and finally tightening with nuts on the other side. This structure is cumbersome to assemble and requires tools for disassembly, making quick assembly and disassembly impossible. More significantly, when replacing the steering wheel, the wiring harness terminals leading out from inside the wheel need to be manually connected to the corresponding wiring harness plugs inside the stroller. Due to the long and messy wiring inside the stroller, the operator typically has to laboriously straighten, pull, and secure multiple wires with one hand, while the other hand, in a narrow space where visibility is limited, relies on touch to locate and align the male and female plugs. During this process, wires easily become tangled or jammed, and plugs are difficult to insert accurately due to orientation issues, often requiring multiple attempts. Improper force can even bend or damage the pins, greatly increasing the time and technical barrier to repair and replacement, resulting in a very poor user experience.

[0004] To address this, we propose a quick-release installation structure for the steering wheel of an electric children's vehicle. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a quick-release installation structure for the steering wheel of an electric children's vehicle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release installation structure for an electric children's car steering wheel, including a children's car steering wheel and a steering shaft. The bottom of the children's car steering wheel is fixedly connected to a mounting base. Both sides of the outer surface of the mounting base are fixedly connected to buckles. The inner surface of the mounting base is fixedly connected to a mounting seat. The bottom of the mounting seat is evenly fixedly connected to a plurality of pluggable male terminals.

[0007] The top of the steering shaft is fixedly connected to a connecting seat, and the mounting seat is positioned and inserted into the top of the connecting seat. Both sides of the outer surface of the connecting seat are fixedly connected to locking mounting parts. Both sides of the outer surface of the two locking mounting parts are rotatably connected to operating handles. Both operating handles are equipped with U-shaped rods, and the U-shaped rods match the buckles.

[0008] The inner side of the connector is equipped with a lifting auxiliary component. The top of the movable end of the lifting auxiliary component is evenly and fixedly connected with multiple pluggable terminal females, and the pluggable terminal females are matched with the pluggable terminal males.

[0009] Furthermore, a U-shaped positioning seat is fixedly connected to the bottom of the assembly base.

[0010] Furthermore, the top of the connecting seat is provided with a positioning groove that communicates with the interior, and the positioning groove matches the U-shaped positioning seat. Through the insertion and cooperation of the U-shaped positioning seat and the positioning groove, circumferential positioning between the steering wheel and the rotating shaft is realized, effectively preventing relative rotation during use.

[0011] Furthermore, both operating handles include two connecting plates, which are located on both sides of the latch mounting member and rotatably connected to it. The ends of the two connecting plates are fixedly connected to the handle body. This structure constitutes a stable lever system, which allows the locking force to be effectively transmitted to the buckle by turning the handle, achieving labor-saving and efficient one-handed operation.

[0012] Furthermore, one side of each of the connecting plates is provided with a pivot that passes through both connecting plates, and the pivot is rotatably connected to the two connecting plates and fixedly sleeved on the outer surface of the U-shaped rod. The pivot serves as the fulcrum of the lever, ensuring that the U-shaped rod can rotate smoothly and hook onto the buckle.

[0013] Furthermore, the lifting auxiliary component includes a knob, which is located at the bottom of the connecting seat. A screw is fixedly connected to the top of the knob, and the screw extends through the bottom of the connecting seat and into the interior, and is rotatably connected to the connecting seat. A movable seat is threaded onto the outer surface of the screw, and multiple pluggable terminal females are evenly fixedly connected to the top of the movable seat. The knob facilitates manual driving of the screw rotation.

[0014] Furthermore, the outer wall of one side of the movable seat slides in contact with the inner wall of one side of the connecting seat. This sliding fit structure effectively prevents the movable seat from rotating with the screw, ensuring that it maintains a stable linear motion during the lifting process.

[0015] The beneficial effects of this utility model are:

[0016] In use, this utility model achieves quick locking and releasing of the steering wheel by engaging the buckle with the U-shaped rod on the operating handle. It also uses a lifting auxiliary component to finely adjust the tightness of the plug-in terminal block connection. Simultaneously, it automatically completes the electrical connection during the mechanical pressing process. This invention solves the core problems of traditional bolt fixing methods, such as cumbersome disassembly and assembly, difficult and time-consuming manual wiring harness connection, and easy loosening of terminal contacts after long-term use. It achieves synchronous, fast, stable and reliable disassembly and assembly of the steering wheel's mechanical structure and electrical connection. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, a quick-release mounting structure for an electric children's vehicle steering wheel is disclosed, including a children's vehicle steering wheel 1 and a steering shaft 3. A mounting base 4 is fixedly connected to the bottom of the children's vehicle steering wheel 1. Buckles 9 are fixedly connected to both sides of the outer surface of the mounting base 4. A mounting seat 12 is fixedly connected to the inner surface of the mounting base 4. A plurality of pluggable terminal males 13 are evenly fixedly connected to the bottom of the mounting seat 12. The pluggable terminal males 13 are electrically connected to the control buttons on the children's vehicle steering wheel 1.

[0026] The bottom of the mounting base 4 is fixedly connected to a U-shaped positioning seat 11, and the top of the steering shaft 3 is fixedly connected to a connecting seat 5. The mounting base 4 is positioned and inserted into the top of the connecting seat 5. The top of the connecting seat 5 has a positioning groove 14 that communicates with the interior, and the positioning groove 14 matches the U-shaped positioning seat 11. The U-shaped positioning seat 11 is usually designed as a rectangular structure. Its core advantage is that it forms an insertion matching relationship with the positioning groove 14 on the top of the connecting seat 5, which can achieve circumferential positioning and prevent the stroller steering wheel 1 from rotating unexpectedly after installation.

[0027] Both sides of the outer surface of the connecting base 5 are fixedly connected to locking mounting parts 10. Both sides of the outer surface of the two locking mounting parts 10 are rotatably connected to operating handles. Each operating handle is equipped with a U-shaped rod 7, which matches the latch 9. Each operating handle includes two connecting plates 8, which are located on both sides of the locking mounting parts 10 and rotatably connected to them. The ends of the two connecting plates 8 are fixedly connected to the handle body 2. One side of each connecting plate 8 has a pivot 6 that passes through both connecting plates 8, and the pivot 6 is rotatably connected to both connecting plates 8 and fixedly sleeved on the outer surface of the U-shaped rod 7. When the user presses down on the handle body 2, the force is amplified and transmitted to the U-shaped rod 7 through the lever principle, causing it to rotate around the pivot 6 and hook the latch 9. The advantage of this design is that it generates a huge locking force with minimal operating force, achieving "quick latch and lock," while the mechanical self-locking characteristic ensures safety and reliability during operation, preventing accidental loosening.

[0028] A lifting auxiliary component is installed on the inner side of the connecting base 5. Multiple pluggable terminal females 17 are evenly fixedly connected to the top of the movable end of the lifting auxiliary component. The pluggable terminal females 17 are electrically connected to the built-in controller of the stroller, and the pluggable terminal females 17 are matched with the pluggable terminal males 13. The lifting auxiliary component includes a knob 16, which is located at the bottom of the connecting base 5. A screw 15 is fixedly connected to the top of the knob 16, and the screw 15 extends through the bottom of the connecting base 5 and is rotatably connected to the connecting base 5. A movable base 18 is threaded onto the outer surface of the screw 15, and multiple pluggable terminal females 17 are evenly fixedly connected to the top of the movable base 18. The outer wall of one side of the movable base 18 slides against the inner wall of one side of the connecting base 5. The thread helix angle of the screw 15 is smaller than the friction angle, so that the screw 15 has a self-locking ability and can prevent it from shifting due to vibration or load.

[0029] Working principle: When installing the stroller steering wheel 1, align the U-shaped positioning seat 11 and insert it into the positioning groove 14. This step ensures circumferential positioning between the stroller steering wheel 1 and the steering shaft 3, preventing relative rotation, and also provides pre-alignment for subsequent electrical connections.

[0030] Subsequently, the handle body 2 and the connecting plate 8 work together to drive the U-shaped rod 7 to rotate via the rotating shaft 6, hooking the U-shaped rod 7 onto the buckle 9 on the mounting base 4. Then, the operating handle is pulled down. During this process, the operating handle uses the lever principle to apply a strong downward pulling and locking force to the buckle 9 through the U-shaped rod 7, thereby pressing the mounting base 4 and the connecting base 5 tightly together, completing the rigid fixation of the mechanical parts.

[0031] At the same time, as the mounting base 4 is pulled down, the pluggable terminal block 13 fixed on it also descends and is inserted into the pluggable terminal block 17 that has been pre-installed on the movable base 18, thereby achieving a one-time synchronous connection of all circuits.

[0032] If poor terminal contact occurs after prolonged use, it can be fine-tuned by rotating knob 16. Knob 16 drives screw 15 to rotate, which in turn drives movable seat 18, which is threaded to it, to rise and fall vertically along the inner wall of connector 5, thereby adjusting the height position of pluggable terminal female head 17 and ensuring that the pluggable terminal male head 13 and pluggable terminal female head 17 always maintain the best tightness of connection.

[0033] When disassembling the stroller steering wheel 1, pull the two operating handles upwards to disengage the U-shaped rod 7 from the latch 9, releasing the mechanical locking state, and then lift the stroller steering wheel 1 directly upwards. At this time, the male plug-in terminal 13 is smoothly pulled out from the female plug-in terminal 17 along with the stroller steering wheel 1. The mechanical structure and electrical connection are separated synchronously and instantly, completing the quick disassembly of the stroller steering wheel 1.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
