[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] See Figures 1 to 17The toy car of the present invention is shown, including a frame 1, a steering rod 4 located at the front of the frame 1 and extending in the vertical direction, and a front wheel assembly 2 located at the bottom of the steering rod 4. The frame 1 includes a main frame 11 with a seat mechanism 7, a left bracket 12 with a left rear wheel assembly 31 at the rear, and a right bracket 13 with a right rear wheel assembly 32 at the rear. The left bracket 12 and the right bracket 13 are rotatably connected to the rear of the main frame 11. The left rear wheel assembly 31 and the right rear wheel assembly 32 constitute the rear wheel assembly 3 and are both omnidirectional wheels.

[0045] The frame 1 is also equipped with a drive mechanism for driving the left support 12 and the right support 13 to rotate relative to the main frame 11, thereby causing the left rear wheel assembly 31 and the right rear wheel assembly 32 to move closer or further apart, and an operating mechanism for driving the drive mechanism. When using the children's toy car of the present invention, the user can sit on the seat mechanism 7 and operate the operating mechanism to drive the drive mechanism, causing the left support 12 and the right support 13 to rotate relative to the main frame 11, and the children's toy car to move forward under the swing drive of the left rear wheel assembly 31 and the right rear wheel assembly 32.

[0046] Specifically, the drive mechanism includes at least a slider 5 that can slide in the front-to-back direction on the main frame 11. The user can drive the slider 5 to slide in the front-to-back direction, thereby driving the left rear wheel assembly 31 and the right rear wheel assembly 32 to move closer or further apart. The left rear wheel assembly 31 and the right rear wheel assembly 32 accelerate to move closer together, which can drive the toy car forward.

[0047] The sliding member 5 can transmit motion to the left support 12 and the right support 13 through tooth meshing, linkage, or a combination of various mechanisms. Gear meshing is preferred as it simplifies the structure and provides more stable and reliable force transmission. The sliding member 5 can be connected to both the left support 12 and the right support 13 via a tooth meshing transmission structure, or it can be connected to one of them via a tooth meshing transmission structure while the other is connected to the former via a tooth meshing transmission structure.

[0048] In a preferred embodiment, the slider 5 is connected to the left support 12 and the right support 13 through a gear meshing transmission structure. When the slider 5 slides, the left support 12 and the right support 13 rotate in opposite directions relative to the main frame 11. Therefore, the sliding of the slider 5 can drive the toy car forward.

[0049] See Figure 2 , Figure 5 , Figure 10As shown, the gear meshing transmission structure includes a first gear set 101 and a second gear set 102 that mesh with each other. The first gear set 101 includes multiple first teeth distributed along the front-rear direction on the sliding member 5; the second gear set 102 includes multiple second teeth arranged along an arc, with the arc of all the second teeth distributed around the center line of rotation of the left support 12 or the right support 13 relative to the main frame 11. The first gear set 101 and the second gear set 102 constitute a gear and rack structure. When the sliding member 5 slides back and forth, the left support 12 and the right support 13 rotate simultaneously.

[0050] The left support 12 and the right support 13 are respectively located on the left and right sides of the sliding member 5. The front of both the left support 12 and the right support 13 is provided with a second tooth set 102. Each side of the sliding member 5 is provided with a first tooth set 101, and the first tooth sets 101 on both sides mesh with the corresponding second tooth sets 102. When the sliding member 5 slides forward, the left support 12 and the right support 13 close together; when the sliding member 5 slides backward, the left support 12 and the right support 13 open together.

[0051] The left support 12 includes a left support rod 121 extending in the front-rear direction and a left connecting rod 122 fixedly mounted on the front end of the left support rod 121. The left connecting rod 122 is fan-shaped and pivotally connected to the rear of the main frame 11. A second gear set 102 is provided on the left connecting rod 122, and a left rear wheel assembly 31 is provided at the bottom rear of the left support rod 121. The right support 13 includes a right support rod 131 extending in the front-rear direction and a right connecting rod 132 fixedly mounted on the front end of the right support rod 131. The right connecting rod 132 is fan-shaped and pivotally connected to the rear of the main frame 11. A second gear set 102 is provided on the right connecting rod 132, and a right rear wheel assembly 32 is provided at the bottom rear of the right support rod 131.

[0052] See Figure 15 and Figure 17 As shown, another preferred method for the sliding member 5 to transmit power to the left support 12 and the right support 13 is a linkage drive. The linkage drive structure includes two connecting rods 103 and 103'. One end of the connecting rod 103 is pivotally connected to the sliding member 5, and the other end is pivotally connected to the left support 12. The sliding member 5, the connecting rod 103, the left support 12, and the main frame 11 constitute a crank-slider mechanism. One end of the connecting rod 103' is pivotally connected to the sliding member 5, and the other end is pivotally connected to the right support 13. The sliding member 5, the connecting rod 103', the right support 13, and the main frame 11 constitute another crank-slider mechanism. When the sliding member 5 slides backward, the left support 12 and the right support 13 open relative to each other. When the sliding member 5 slides forward, the left support 12 and the right support 13 move closer together.

[0053] The children's toy car also includes a reset device, which includes an elastic element for providing the elastic force required for the slider 5 to move forward relative to the main frame 11. With the help of the elastic element, it is easier to manipulate the slider 5 to move forward, making it easier for the left rear wheel assembly 31 and the right rear wheel assembly 32 to accelerate and move closer to each other, so as to provide the toy car with forward acceleration.

[0054] Specifically, the elastic element is a tension spring 6. One end of the tension spring 6 is connected to the front end of the slider 5, and the other end is connected to the steering rod 4. When the slider 5 slides backward, the tension spring 6 is in a tensioned state.

[0055] The sliding member 5 has a guide groove 51 extending in the front-to-back direction. The main frame 11 is fixedly provided with a limiting block 14 that fits into the guide groove 51. The guide groove 51 and the limiting block 14 cooperate to ensure that the sliding member 5 slides in the front-to-back direction, while also limiting the range of motion of the sliding member 5, preventing it from detaching from the main frame 11 and preventing damage to other parts caused by collisions. See also Figure 2 , Figure 5 , Figure 10 As shown, there are two guide grooves 51 and two limit blocks 14.

[0056] See Figure 3 , Figure 6 , Figure 8 , Figure 11 As shown, the main frame 11 includes a main body rod 111 extending in the front-rear direction, and a sliding member 5 is slidably mounted on the main body rod 111, so the sliding member 5 slides relatively smoothly.

[0057] The main frame 11 also includes a rear connecting rod 112 located at its rear and extending in the left-right direction, with a left bracket 12 pivotally connected to the left end of the rear connecting rod 112 and a right bracket 13 pivotally connected to the right end of the rear connecting rod 112.

[0058] The forward and backward movement of the operating mechanism drives the drive mechanism to operate. It can be configured in various ways. These configurations, combined with the drive mechanisms of the different structures described above, can produce a variety of implementation methods. The following is a further explanation of the preferred implementation method of the present invention.

[0059] Example 1

[0060] See Figures 1 to 6In one embodiment of the present invention, the steering lever 4 includes a front fork 42 and a handlebar 41. The front wheel assembly 2 is located at the bottom of the front fork 42. The upper part of the front fork 42 and the lower part of the handlebar 41 are rotatably connected via a universal joint 44. A connecting assembly is provided between the handlebar 41 and the sliding member 5 for driving the sliding member 5 to slide back and forth when the handlebar 41 rotates relative to the front fork 42. Since the front fork 42 and the handlebar 41 are universally rotatable, the handlebar 41 can still control the front fork 42 to rotate around its own axis even when the front fork 42 and the handlebar 41 extend in different directions.

[0061] The connecting assembly includes a sleeve 43 rotatably mounted on the handlebar 41 and pivotally connected at one end to the sleeve 43 and at the other end to the slider 5. The handlebar 41, fork 42, link 8, main frame 11, and slider 5 constitute a crank-slider mechanism. When the user pulls the handlebar 41 backward, the slider 5 slides backward along the main frame 11, and the left support 12 and right support 13 open to the sides. When the user pushes the handlebar 41 forward, the slider 5 slides forward along the main frame 11, and the left support 12 and right support 13 move closer together. The user drives the toy car entirely with their upper limbs, providing excellent exercise for the upper limbs.

[0062] Example 2

[0063] See Figures 7 to 11 This is Embodiment Two of the present invention. The structure of Embodiment Two is basically the same as that of Embodiment One, with the main difference being the structure of the operating mechanism. The seat mechanism 7 is slidably mounted on the main frame 11 in the front-to-back direction. The user drives the seat mechanism 7 to move back and forth, thereby causing the sliding member 5 to move back and forth. To drive the movement of the seat mechanism 7, the user needs to use both hands and feet, resulting in a better exercise effect.

[0064] The main frame 11 is provided with a slide 15 that can slide relative to it in the front-rear direction and extends in the front-rear direction. The slide 15 is fixedly connected to the sliding member 5, and the seat mechanism 7 is fixedly mounted on the slide 15. A limit groove 51 is also provided on the slide 15. Correspondingly, a limit block 14 that fits through the limit groove 51 is also fixedly provided on the main frame 11.

[0065] In other embodiments, the seat mechanism 7 may also be connected to the slider 5 by other transmission methods, which may amplify or reduce the transmission ratio between the seat mechanism 7 and the slider 5.

[0066] In the second embodiment, since it is not necessary to drive the slider 5 to move back and forth through the front fork 42, the front fork 42 and the handlebar 41 can be set as one piece; the front fork 42 and the handlebar 41 can also be rotatably connected through the universal joint 44 to improve the flexibility of the toy car.

[0067] Example 3

[0068] See Figure 12 This is Embodiment 3 of the present invention. The structure of Embodiment 3 is basically the same as that of Embodiment 1. The main difference is that the seat mechanism 7 can move with the movement of the slider 5. Specifically, the main frame 11 is provided with a slide 15 that can slide relative to it in the front-back direction and extends in the front-back direction. The slide 15 is fixedly connected to the slider 5, and the seat mechanism 7 is fixedly mounted on the slide 15.

[0069] When using this children's toy car, users can drive the toy car by operating the handlebars 41, by operating the seat mechanism 7, or by combining the two methods. This toy car provides more ways to play and can meet the various needs of children.

[0070] Example 4

[0071] See Figures 13 to 17 This is Embodiment Four of the present invention. The operating mechanism of Embodiment Four is the same as that of Embodiment One, with the main difference being that the driving mechanism of Embodiment Four is a linkage transmission structure as described above. The user can rotate the handlebar 41 back and forth to drive the left support 12 and the right support 13 to move closer together and open, thereby propelling the toy car forward. Specifically, the toy car of Embodiment Four is equipped with two connecting rods 103 and 103'. One end of connecting rod 103 is pivotally connected to the slider 5, and the other end is pivotally connected to the left support 12. The slider 5, connecting rod 103, left support 12, and main frame 11 constitute a crank-slider mechanism. One end of connecting rod 103' is pivotally connected to the slider 5, and the other end is pivotally connected to the right support 13. The slider 5, connecting rod 103', right support 13, and main frame 11 constitute another crank-slider mechanism. When the slider 5 slides backward, the left support 12 and the right support 13 open relative to each other; when the slider 5 slides forward, the left support 12 and the right support 13 move closer together.

[0072] In summary, when using the children's toy car of the present invention, the user can sit on the seat mechanism 7 and drive the left support 12 and right support 13 relative to the main frame 11 by manipulating the drive mechanism through the steering lever 4 or the seat mechanism 7. This causes the left rear wheel assembly 31 and right rear wheel assembly 32 to move closer or further apart, thereby giving the toy car forward power and achieving the effect of seated driving. Compared with the existing standing-driven frog car, this provides a new way to play. Children can exercise their limbs while using the toy car, increasing the fun of the toy car.

[0073] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
