Description

Technical Field

[0001] This utility model relates to the field of children's toys, specifically to a children's toy motorcycle that can quickly switch the rear wheel steering mode through a mechanical structure. Background Technology

[0002] Most existing children's scooters use a fixed front wheel or swivel wheels. Fixed wheels offer poor flexibility and cannot achieve multi-directional gliding; swivel wheels result in insufficient stability when traveling in a straight line, making them prone to tipping over. Some products attempt to switch modes via electronic buttons, but these are costly, easily damaged, and complex to operate, making them unsuitable for young children. Therefore, there is an urgent need for a simple, accident-proof switching device with automatic alignment. Utility Model Content

[0003] The purpose of this invention is to solve the aforementioned problems in the existing technology and to provide a children's toy motorcycle that can quickly switch the rear wheel steering mode through a mechanical structure.

[0004] According to this utility model, a children's toy motorcycle with switchable steering modes includes a frame, a front wheel assembly, and a rear wheel assembly. The front wheel assembly includes a omnidirectionally rotatable front wheel, and the rear wheel assembly includes a rear wheel that can switch between omnidirectional and directional modes. The wheel frame of the rear wheel is provided with a locking groove, and the wheel frame is provided with a locking mechanism. The locking mechanism includes a locking pin that can move horizontally, a push block that is linked to the locking pin, and a slidable switching key located on the side of the wheel frame. The switching key drives the locking pin to engage or disengage from the locking groove via the push block. When the locking pin is inserted into the locking groove, the rear wheel switches to directional mode; when the locking pin disengages from the locking groove, the rear wheel returns to omnidirectional mode.

[0005] As a further embodiment of this utility model, the locking pin is provided with a return spring, which provides a preload force to the locking pin toward the locking groove.

[0006] As a further embodiment of this utility model, the locking pin and the locking groove are an interference fit structure, and the inlet end of the locking groove is provided with a guide slope.

[0007] When the switch is in directional mode but the locking pin is not aligned with the locking slot (e.g., due to a child's misalignment), the child simply needs to push the vehicle forward naturally. As the rear wheels rotate, the guide ramp of the locking slot will contact the end of the locking pin. Under the combined action of the wheel frame's rotational torque and the return spring's elasticity, the locking pin slides along the guide ramp into the locking slot, achieving automatic alignment and locking. This design significantly reduces the precision requirements for operation and improves ease of use for children.

[0008] As a further embodiment of this invention, the push block is provided with a positioning structure, which includes a compression spring and a positioning rod connected to the compression spring. The wheel frame is provided with a positioning groove adapted to the positioning rod. When the switch key slides between omnidirectional mode and directional mode, the switch key drives the push block, and the positioning rod is engaged in the corresponding positioning groove under the elastic force of the compression spring, thereby fixing the position of the switch key.

[0009] One end of the compression spring is fixed inside the switch button, and the other end is connected to the positioning rod. The rear wheel frame is made of nylon, and there are two positioning grooves on the frame, corresponding to the omnidirectional mode and the directional mode respectively.

[0010] When the switch button is pushed, the switch button drives the push block, and the positioning rod is squeezed by the wheel frame surface, which forces the compression spring to compress until the switch button moves to the target position. The spring releases its elasticity and pushes the positioning rod into the corresponding positioning groove, while producing a clear "click" tactile feedback, ensuring that children can perceive the switching completion status when operating.

[0011] As a further embodiment of this utility model, the front wheel assembly includes two omnidirectionally rotatable front wheels, and the rear wheel assembly includes two rear wheels that can switch between omnidirectional and directional modes; the locking pins in the locking mechanisms of the two rear wheels are connected together by a linkage rod, and pushing the switching key drives the linkage rod through the push block to realize that the locking pins of the two rear wheels are simultaneously engaged or disengaged from the locking grooves.

[0012] The beneficial effects of this utility model are as follows: 1. The mechanical switching structure is low-cost, simple to operate, and highly reliable, making it suitable for children's use. The purely mechanical structure avoids electronic component failures. 2. The dual-mode design balances driving stability and fun (directional mode improves straight-line stability, while omnidirectional mode enhances the fun of control). 3. The interference fit and guide slope design enable automatic alignment of the locking pin, reducing the precision requirements for operation and avoiding locking failure due to misalignment during switching. 4. The return spring and interference fit work together to ensure the stability of the directional mode during driving and prevent accidental unlocking. 5. The gear positioning structure uses mechanical feedback to prevent the switching key from being misaligned and to prevent accidental mode switching due to vibration during use. 6. The combination design of the compression spring and positioning rod simplifies the operation force and is suitable for children's hand strength. Attached Figure Description

[0025] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-6 As shown, the children's toy motorcycle with switchable steering modes includes a frame 1, a front wheel assembly 2, and a rear wheel assembly 3. The front wheel assembly 2 includes a swivel-rotating front wheel 21, and the rear wheel assembly 3 includes a rear wheel 31 that can switch between swivel and directional modes. The wheel frame 311 of the rear wheel 31 is provided with a locking groove 312, and the wheel frame 311 is provided with a locking mechanism 4. The locking mechanism 4 includes a locking pin 41 that can move horizontally, a push block 42 that is linked to the locking pin 41, and a slidable switch key 43 located on the side of the wheel frame 311. The switch key 43 drives the locking pin 41 to engage or disengage from the locking groove 312 through the push block 42. When the locking pin 41 is inserted into the locking groove 312, the rear wheel 31 switches to directional mode. When the locking pin 41 disengages from the locking groove 312, the rear wheel 31 returns to swivel mode.

[0027] In a preferred embodiment, the locking pin 41 is provided with a return spring 411, which provides a preload force to the locking pin 41 toward the locking groove 312.

[0028] In a preferred embodiment, the locking pin 41 and the locking groove 312 are interference-fitted, and the entrance end of the locking groove 312 is provided with a guide slope 3121. When the switch key 43 has been switched to the directional mode, but the locking pin 41 is not aligned with the locking groove 312 (e.g., the child's operation is not fully aligned), the child only needs to naturally push the vehicle body to glide. During the rotation of the rear wheel 31, the guide slope 3121 of the locking groove 312 will contact the end of the locking pin 41. Under the combined action of the rotational torque of the wheel frame 311 and the elastic force of the return spring 411, the locking pin 41 slides into the locking groove 312 along the guide slope 3121, achieving automatic alignment and locking. This design significantly reduces the accuracy requirements of operation and improves the convenience for children to use.

[0029] In a preferred embodiment, the push block 42 is provided with a positioning structure 5, which includes a compression spring 51 and a positioning rod 52 connected to the compression spring 51. The wheel frame 311 is provided with a positioning groove 313 that is adapted to the positioning rod 52.

[0030] When the switch key 43 slides between the universal mode and the directional mode, the switch key 43 drives the push block 42, and the positioning rod 52 is inserted into the corresponding positioning groove 313 under the elastic force of the compression spring 51, thereby fixing the position of the switch key 43.

[0031] One end of the compression spring 51 is fixed inside the switch key 43, and the other end is connected to the positioning rod 52. The wheel frame 311 of the rear wheel 31 is made of nylon material, and two positioning grooves 313 are provided on the wheel frame 311, corresponding to the omnidirectional mode and the directional mode respectively.

[0032] When the switch button 43 is pushed, the switch button 43 drives the push block 42. The positioning rod 52 is squeezed by the surface of the wheel frame 311, which forces the compression spring 51 to compress until the switch button 43 moves to the target position. The spring 51 releases its elasticity and pushes the positioning rod 52 into the corresponding positioning groove 313, while producing a clear "click" tactile feedback to ensure that children can perceive the switching completion status when operating.

[0033] In a preferred embodiment, the front wheel assembly 2 includes two omnidirectionally rotatable front wheels 21; the rear wheel assembly 3 includes two rear wheels 31 that can switch between omnidirectional and directional modes; the locking pins 41 in the locking mechanism 4 of the two rear wheels 31 are connected together by a linkage rod 45, and the switching key 43 is pushed to drive the linkage rod 45 through the push block 42, so that the locking pins 41 of the two rear wheels 31 can be simultaneously engaged or disengaged from the locking grooves 312.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
