Description

Technical Field

[0001] This utility model relates to the field of toy cars, and in particular to a toy car steering mechanism and a toy car. Background Technology

[0002] Toy cars, as an important medium in children's entertainment and model collecting, typically include core components such as a frame, drive system, steering mechanism, and wheels. Traditional toy cars achieve movement by driving the wheels with an electric motor and use mechanical transmission structures (such as gear sets, linkages, or servo motors) to control the wheel deflection to complete steering actions.

[0003] Existing toy cars still have certain shortcomings: First, when toy cars are turning and moving simultaneously, they are prone to frictional resistance or jamming (for example, when the drive motor is working, the steering mechanism may be forced to deviate), resulting in reduced efficiency and increased wear and tear on parts. Second, toy cars often require multiple separate drive chains (such as additional steering servos or couplings), resulting in large size and difficult assembly. Utility Model Content

In the toy car steering mechanism, two integrally formed transmission parts are provided on the transmission head, and the two transmission parts are configured to slide in cooperation with two transmission grooves on the inner wall of the transmission sleeve.

[0043] Figure 1 and Figure 2 The illustration shows a toy car 20 in some embodiments of the present invention. The toy car is equipped with a toy car steering mechanism 10, which is mounted on a frame 50. The toy car steering mechanism 10 can both move the frame 50 and turn the toy car, changing its direction of movement.

[0044] like Figure 3 As shown, the toy car steering mechanism 10 includes a power unit 1, a transmission unit 2, and a steering mechanism 3. The power unit 1, transmission unit 2, and steering mechanism 3 are respectively mounted on the frame 50. The power unit 1 is driven and connected to the transmission unit 2, and the transmission unit 2 is driven and connected to the steering mechanism 3. It should be noted that the power unit 1 is used to output torque during operation, and the transmission unit 2 is used to transmit the torque to the steering mechanism 3.

[0045] The power unit 1 includes a travel motor 11 and a steering motor 12.

[0046] It should be noted that the drive motor 11 is used to output torque during operation to drive the toy car's movement. The steering motor 12 is used to output torque during operation to drive the toy car's steering movement.

[0047] like Figures 3 to 7 As shown, the transmission device 2 includes a travel transmission structure 21 and a steering transmission structure 22. The travel transmission structure 21 is rotatably mounted on the frame and driven to the travel motor 11, while the steering transmission structure 22 is slidably mounted on the frame and driven to the steering motor 12.

[0048] It should be noted that the travel transmission structure 21 is used to receive the torque of the travel motor 11 and transmit it to the travel steering device 3. The steering transmission structure 22 is used to receive the torque of the steering motor 12 and transmit it to the travel steering device 3 to drive the steering motion.

[0049] The travel steering device 3 includes a power shaft 31, a transmission head 32, a transmission sleeve 33, a steering sleeve 34, and a wheel 35. The power shaft 31 is driven and connected to the travel transmission structure 21. The transmission head 32 is fixedly connected to the power shaft 31. Two transmission parts 321 are integrally formed on the transmission head 32. Two transmission grooves 333 are opened on the inner wall of the transmission sleeve 33. The transmission sleeve 33 is sleeved on the outside of the transmission head 32, and the two transmission parts 321 are slidably arranged in the two transmission grooves 333 in a one-to-one correspondence. The transmission sleeve 33 passes through the steering sleeve 34 and is driven and connected to the wheel 35. The steering sleeve 34 is rotatably mounted on the frame 50 and is rotatably connected to the steering transmission structure 22.

[0050] When the steering transmission structure 22 slides, it drives the steering sleeve 34 to rotate on the frame 50, thereby the steering sleeve 34 drives the wheel 35 to turn through the transmission sleeve 33, so that the two transmission parts 321 slide along the transmission groove 333 respectively.

[0051] When the travel transmission structure 21 rotates, the power shaft 31 drives the transmission head 32 to rotate, thereby driving the transmission sleeve 33 to rotate relative to the steering sleeve 34 by the transmission part 321 pressing against the groove wall of the transmission slide 333, and thus driving the wheel 35 to rotate.

[0052] It should be noted that the drive shaft 31 is used to receive and transmit the torque of the travel transmission structure 21. The transmission head 32 is fixedly connected to the drive shaft 31, and the transmission part 321 of the transmission head 32 is used to slide and engage with the transmission groove 333 of the transmission sleeve 33 to adapt to displacement during steering. The transmission sleeve 33 is used to rotate under the support of the transmission part 321, thereby driving the wheel 35 to rotate. The steering sleeve 34 is used to rotate under the drive of the steering transmission structure 22 to change the steering direction of the wheel 35; the wheel 35 is used to provide the movement and steering functions of the toy car.

[0053] This invention achieves adaptive displacement when the wheel 35 turns by sliding the transmission part 321 and the transmission groove 333, avoiding forced offset friction and reducing component wear and kinetic energy loss. The steering transmission structure 22 is directly slidably mounted on the frame 50 and drives the steering sleeve 34 to rotate. At the same time, the transmission sleeve 33 passes through the steering sleeve 34 to transmit power, achieving a high degree of integration of the transmission path, reducing volume and assembly complexity. The travel transmission structure 21 drives the power shaft 31 to rotate the transmission head 32. The transmission part 321 holds the transmission groove 333 and pushes the transmission sleeve 33 to rotate relative to the steering sleeve 34, ensuring that the travel and steering movements do not interfere with each other and improving travel efficiency.

[0054] like Figures 4 to 7 As shown, in some embodiments of the toy car steering mechanism 10, one end of the transmission sleeve 33 is provided with a connecting shaft 331, and the other end of the transmission sleeve 33 is provided with a receiving groove 332.

[0055] The connecting shaft 331 is inserted into the wheel 35, and the receiving groove 332 is used to receive the transmission head 32. The opening of the receiving groove 332 has two clearance notches 334, and the two clearance notches 334 are connected to the two transmission slides 333 one by one.

[0056] Understandably, the connecting shaft 331 is used to directly transmit torque to the wheel 35, achieving a rigid connection between the transmission sleeve 33 and the wheel 35. The receiving groove 332 is used to accommodate the transmission head 32, providing sliding fit space between the transmission part 321 and the transmission slide 333. The clearance notch 334 connects the receiving groove 332 and the transmission slide 333, preventing structural interference between the transmission head 32 and the transmission sleeve 33 during steering displacement. Simultaneously, during the assembly of the transmission head 32 and the transmission sleeve 33, the clearance notch 334 prevents the transmission part 321 from getting stuck outside the receiving groove 332 and also guides the transmission part 321 and the transmission slide 333 to quickly and correctly align.

[0057] like Figures 5 to 7 As shown, in some embodiments of the toy car steering mechanism 10, the travel steering device 3 includes two drive heads 32, two drive sleeves 33, two steering sleeves 34 and two wheels 35.

[0058] Two transmission heads 32 are respectively disposed at both ends of the power shaft 31. Two transmission sleeves 33 are respectively sleeved on the two transmission heads 32. Two transmission sleeves 33 are respectively passed through the two steering sleeves 34. The two transmission sleeves 33 are respectively driven and connected to the two wheels 35. The two steering sleeves 34 are respectively rotatably disposed on the frame 50. The two steering sleeves 34 are respectively rotatably connected to the steering transmission structure 22.

[0059] When the steering transmission structure 22 slides, it drives the two steering sleeves 34 to rotate on the frame 50, thereby driving the two wheels 35 to turn through the two transmission sleeves 33 respectively.

[0060] Understandably, the two drive heads 32 are used to synchronously transmit torque to the two drive sleeves 33 on both sides. The two drive sleeves 33 are independently sleeved on the drive heads 32 and pass through the steering sleeves 34 to realize the power output of the two wheels 35 on both sides. The steering transmission structure 22 is used to link the two steering sleeves 34, that is, to synchronously drive the two steering sleeves 34 to rotate through a single sliding action of the steering transmission structure 22.

[0061] It should be noted that the symmetrical layout in this embodiment ensures consistent steering of the two wheels 35. The integrated design of the steering transmission structure 22 uses a single input to control dual outputs, simplifying the steering control logic and reducing energy consumption.

[0062] like Figures 5 to 7 As shown, in some embodiments of the toy car steering mechanism 10, the travel steering device 3 also includes a shock-absorbing spring 36;

[0063] The steering sleeve 34 is provided with a steering shaft 341 and a movable arm 342. The steering shaft 341 is rotatably connected to the frame 50. The shock absorber spring 36 is sleeved on the steering shaft 341 and abuts against the steering sleeve 34 and the frame 50 respectively. The movable arm 342 is rotatably connected to the steering transmission structure 22.

[0064] Understandably, the shock absorber spring 36 is used to absorb the impact vibrations of the wheel 35 during travel, maintaining a stable connection between the steering sleeve 34 and the frame 50. The movable arm 342 is used to convert the displacement of the steering transmission structure 22 into the rotation of the steering sleeve 34. The steering shaft 341 carries the shock absorber spring 36 and provides a pivot point for rotation, ensuring that the steering sleeve 34 rotates around the shaft and guaranteeing steering accuracy.

[0065] It should be noted that the shock-absorbing spring 36 effectively buffers road impacts and prevents gear transmission structures from loosening due to vibration. The rigid linkage between the movable arm 342 and the steering shaft 341 improves steering response sensitivity.

[0066] like Figures 4 to 7As shown, in some embodiments of the toy car steering mechanism 10, the steering transmission structure 22 includes a guide head 221, a slide 222 and a reversing arm 223. The guide head 221 is provided with an eccentric guide part 2211, the slide 222 is provided with a guide channel 2221, and the reversing arm 223 is provided with a movable hole 2231.

[0067] Steering motor 12 is driven and connected to guide head 221, slide block 222 is slidably mounted on frame 50, eccentric guide part 2211 is slidably connected to guide channel 2221, reversing arm 223 is mounted on slide block 222, and steering sleeve 34 is rotatably connected to movable hole 2231;

[0068] When the guide head 221 rotates, it slides against the side wall of the guide channel 2221 through the eccentric guide part 2211, so that the slide block 222 slides relative to the frame 50, and then drives the steering sleeve 34 to rotate through the reversing arm 223.

[0069] Understandably, the eccentric guide 2211 converts the rotational motion of the steering motor 12 into eccentric sliding, driving the linear displacement of the slide 222. The guide channel 2221 constrains the sliding trajectory of the eccentric guide 2211, converting the eccentric motion into directional linear motion of the slide 222. The movable hole accommodates the rotating connection end of the steering sleeve 34, adapting to the axial offset when the steering sleeve 34 rotates. The reversing arm 223 links the slide 222 and the steering sleeve 34, thereby converting the linear displacement of the slide 222 into the rotation of the steering sleeve 34.

[0070] like Figures 4 to 7 As shown, in some embodiments of the toy car steering mechanism 10, the travel transmission structure 21 includes a drive shaft 211, a power gear 212, and several output gears 213.

[0071] One end of the drive shaft 211 is provided with a first drive gear 2111, and the other end of the drive shaft 211 is provided with a second drive gear 2112. The power gear 212 is fixedly sleeved on the power shaft 31. Each output gear 213 is rotatably mounted on the frame 50. Each output gear 213 meshes in sequence, and one of the output gears 213 is driven and connected to the travel motor 11. The other output gear 213 meshes with the first drive gear 2111, and the second drive gear 2112 meshes with the power gear 212.

[0072] Understandably, the first drive gear 2111 is used to receive the torque transmitted via the output gear 213, thereby further driving the drive shaft 211 to rotate. The second drive gear 2112 is used to transmit the torque to the power gear 212, thereby driving the power shaft 31 to rotate via the power gear 212. The various output gears 213 mesh sequentially to transmit torque.

[0073] like Figure 3 and Figure 4 As shown, in some embodiments of the toy car steering mechanism 10, the toy car steering mechanism 10 also includes a moving device 4; see also Figure 4 and Figure 6 The moving device 4 includes a moving shaft 41 and two moving wheels 42. The moving shaft 41 is fixed to one of the output gears 213, and the two moving wheels 42 are respectively fixed at both ends of the moving shaft 41.

[0074] Understandably, the movable shaft 41 is fixed to the output gear 213 to convert the rotational torque of the output gear 213 into the driving force of the movable wheel 42. The movable wheel 42 is used to rotate under the drive of the movable shaft 41, thereby driving the toy car 20 to move.

[0075] It should be noted that the output gear 213 drives the moving wheel 42 in conjunction with the wheel 35, thereby reducing the load pressure on the wheel and improving the passability on complex road surfaces. Figures 4 to 7 As shown, in some embodiments of the toy car steering mechanism 10, the travel steering device 3 further includes a rotary bearing 37, which is disposed on the frame 50, and the transmission head 32 is disposed on the inner ring of the rotary bearing 37.

[0076] It should be noted that the inner ring of the rotating bearing 37 fixes the transmission head 32, while the outer ring of the rotating bearing 37 is fixed to the frame 50. The rotating bearing 37 is used to support the rotation of the transmission head 32.

[0077] It should also be noted that by mounting the transmission head 32 with the rotating bearing 37, the radial runout and axial movement of the transmission head 32 can be constrained by the bearing structure, thereby improving the reliability of the power output of the travel steering device 3 and the stability during steering.

[0078] Eliminating axial wear between the transmission head 32 and the transmission sleeve 33, rigid support ensures precise meshing between the transmission part 321 and the transmission groove 333, reducing kinetic energy loss by 15%.

[0079] Figures 1 to 5 The toy car 20 in some embodiments of the present invention is shown. The toy car 20 includes a frame 50, a power supply device 30 and a toy car steering mechanism 10. The toy car steering mechanism 10 is disposed on the frame 50, and the power supply device 30 is disposed on the frame 50. The power supply device 30 is electrically connected to the drive motor 11 and the steering motor 12 respectively.

[0080] Understandably, the frame 50 provides a mounting location for the power supply unit 30, the toy car steering mechanism 10, and other devices. The power supply unit 30 provides electrical power to the toy car steering mechanism 10.

[0081] It should be noted that the power supply device 30 can be configured as a rechargeable battery or a non-rechargeable battery. Furthermore, the power supply device 30 can be configured to be detachably mounted on the frame 50.

[0082] like Figure 3 As shown, in some embodiments of the toy car 20, the toy car 20 also includes a circuit board 40, which is disposed on the frame 50 and is electrically connected to the power supply device, the drive motor 11 and the steering motor 12 respectively.

[0083] Understandably, circuit board 40 is used to control the operation of the drive motor 11, steering motor 12, and other electrical components on the toy car 20. A remote communication module can be added to circuit board 40 to enable users to remotely control the movement, steering, and other functions (such as sound and light components) of the toy car 20.

[0084] The following are the beneficial effects of implementing this utility model:

[0085] This utility model relates to a steering mechanism for a toy car 20 and the toy car 20 itself. The toy car 20 is equipped with a steering mechanism. In the steering mechanism, two integrally formed transmission parts are provided on the transmission head, and these two transmission parts are configured to slide in contact with two transmission grooves on the inner wall of the transmission sleeve. When the wheel turns, the transmission parts adaptively displace along the transmission grooves, thereby avoiding forced offset friction caused when the drive motor and steering motor operate simultaneously, significantly reducing component wear and kinetic energy loss.

[0086] Secondly, by directly sliding the steering transmission structure onto the frame and driving the steering sleeve to rotate, while the transmission sleeve passes through the steering sleeve to transmit power, there is no need to set up the separate servo linkage device or coupling in the prior art, thus achieving a high degree of integration of the transmission path, effectively reducing the volume and assembly complexity.

[0087] In addition, the drive shaft is driven by the travel transmission structure to rotate the transmission head. The transmission part holds the groove wall of the transmission slide and pushes the transmission sleeve to rotate relative to the steering sleeve, ensuring that the wheel rotation and steering motion do not interfere with each other, maintaining a rigid torque transmission path between the drive shaft and the wheel, and improving travel efficiency.

[0088] The present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have different focuses; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. Those skilled in the art should also understand that the actions and modules involved in the specification are not necessarily essential to the present invention. Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the modules in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.

[0089] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
