The saddle assembly 4 can slide on the frame 1 in the up-down and front-back directions, the pedal assembly 6 can slide on the frame 1 in the front-back directions, and the handlebar 5 can rotate and slide on the frame 1 in the up-down and front-back directions. In this way, the saddle assembly 4, the handlebar 5 and the pedal assembly 6 can be slidably adjusted relative to the frame 1, so that the children's toy car has a variety of riding states to increase the entertainment of the children's toy car.

The frame 1 includes a bottom frame 11 at the bottom, an upper frame 12 above the bottom frame 11, a rear frame 13 at the rear, and a first front frame 14 and a second front frame 15 at the front. The bottom frame 11 and the upper frame 12 both extend in the front-to-back direction, the rear frame 13 extends obliquely in the up-down direction, the first front frame 14 and the second front frame 15 also extend obliquely in the up-down direction, and the first front frame 14 is located above the second front frame 15. The first front frame 14 and the second front frame 15 are arranged between the front end of the bottom frame 11 and the front end of the upper frame 12, and the rear frame 13 is arranged between the rear end of the bottom frame 11 and the rear end of the upper frame 12. In this embodiment, the second front frame 15, the first front frame 14, the upper frame 12, the rear frame 13, and the bottom frame 11 are arranged in a closed frame structure in a head-to-tail order, which makes the frame 1 stable and neat and beautiful in appearance.

The saddle assembly 4 can be slidably arranged on the rear frame 13 along the length extension direction of the rear frame 13. Specifically, the saddle assembly 4 includes a seat 41 for a child to sit on and a first sliding sleeve 42 arranged at the bottom of the seat 41, and the first sliding sleeve 42 is sleeved on the rear frame 13 and can be slidably arranged along the length extension direction of the rear frame 13.

A second sleeve 141 is fixedly provided at the front portion of the first front frame 14. The second sleeve 141 has a tubular cavity extending along the length direction of the first front frame 14. The second sleeve 141 is sleeved on the outside of the handlebar 5. The handlebar 5 can be rotatably arranged around its own axis relative to the second sleeve 141, and the handlebar 5 can also be slidably arranged relative to the second sleeve 141 along the length extension direction of the tubular cavity of the second sleeve 141.

The pedal assembly 6 includes a main rod 61 extending in the front-to-back direction and a pedal rod 62 arranged on the main rod 61 and extending in the left-to-right direction, and the pedal rod 62 is used for children to step on. A plurality of support seats 111 are arranged at intervals in the front-to-back direction on the base frame 11, and each support seat 111 has a receiving cavity matching the main rod 61. The main rod 61 is sequentially arranged in the receiving cavities of each support seat 111, and can be slidably arranged relative to each receiving cavity in the front-to-back direction.

The saddle assembly 4 is slidably connected to the pedal assembly 6. The children's toy car also includes a linkage mechanism, which is arranged between the pedal assembly 6 and the handlebar 5 and is matched or connected to the pedal assembly 6 and the handlebar 5 respectively. In this way, when any one of the saddle assembly 4, the handlebar 5 and the pedal assembly 6 slides relative to the frame 1, the other two can be driven to slide synchronously relative to the frame 1. In this way, when the children's toy car is adjusted in a riding state, it is not necessary to operate the saddle assembly 4, the handlebar 5 and the pedal assembly 6 separately to adjust their positions. As long as one of the components is operated to adjust the position, the other two components can be adjusted to positions adapted to the component, so that the children's toy car can be easily switched between various riding states, and the safety performance of the children's toy car can also be improved.

As shown in Fig. 1 to Fig. 4 and Fig. 6, the linkage mechanism includes a first link 71 and a second link 72. The first link 71 is slidably disposed on the frame 1, and the second link 72 is rotatably disposed on the frame 1 via a third shaft 83. One end of the first link 71 is slidably connected to the pedal assembly 6, the first link 71 and one end of the second link 72 are rotatably and slidably connected, and the other end of the second link 72 is rotatably and slidably connected to the handlebar 5.

Specifically, the pedal assembly 6 further includes a second connecting member 63 fixedly arranged on the main rod 61, a first slide groove 631 is arranged on one of the second connecting member 63 and the first connecting rod 71, and a first connecting column 711 matched with the first slide groove 631 is fixedly arranged on the other, the extension direction of the first slide groove 631 is obliquely intersected with the sliding direction of the first connecting rod 71, and the first connecting column 711 is located in the first slide groove 631 and can be slidably arranged along the length extension direction of the first slide groove 631. In this embodiment, the first slide groove 631 is arranged on the second connecting member 63, and the first connecting column 711 is fixedly arranged on the first connecting rod 71. In this way, when the pedal assembly 6 slides in the front-rear direction relative to the frame 1, the first connecting rod 71 is driven to slide in the up-down direction relative to the frame 1 through the cooperation of the first slide groove 631 and the first connecting column 711.

One end of the first link 71 is rotatably connected with the second link 72 through the first shaft 81, a second slide groove 721 is provided on one of the first link 71 and the second link 72, the first shaft 81 is provided on the other of the first link 71 and the second link 72, the extension direction of the second slide groove 721 is inclined or perpendicular to the sliding direction of the first link 71, the first shaft 81 is rotatably provided in the second slide groove 721, and can be slidably provided along the length extension direction of the second slide groove 721. In this embodiment, the second slide groove 721 is provided on the second link 72, and the first shaft 81 is provided on the first link 71. In this way, when the first link 71 slides in the up-down direction relative to the frame 1, the second link 72 rotates relative to the frame 1 around the third shaft 83 through the cooperation of the second slide groove 721 and the first shaft 81.

The other end of the second connecting rod 72 is rotatably connected to the handlebar 5 via the second shaft 82. A third slide groove 722 is provided on one of the second connecting rod 72 and the handlebar 5. The second shaft 82 is provided on the other of the second connecting rod 72 and the handlebar 5. The third slide groove 722 extends in the front-rear direction. The second shaft 82 is rotatably provided in the third slide groove 722 and can be slidably provided along the length extension direction of the third slide groove 722. In this embodiment, the third slide groove 722 is provided on the second connecting rod 72, and the second shaft 82 is provided on the handlebar 5. In this way, when the second connecting rod 72 rotates relative to the frame 1 around the third shaft 83, the handlebar 5 slides up and down relative to the frame 1 through the cooperation between the third slide groove 722 and the second shaft 82.

Preferably, the first shaft 81 and the second shaft 82 are respectively arranged on opposite sides of the third shaft 83. In this way, when the first connecting rod 71 slides upward relative to the frame 1, the handlebar 5 is driven to slide downward relative to the frame 1. Conversely, when the first connecting rod 71 slides downward relative to the frame 1, the handlebar 5 is driven to slide upward relative to the frame 1.

The saddle assembly 4 further includes a first connecting member 43 disposed below the seat 41, and the first connecting member 43 extends downward from the lower end surface of the first sliding sleeve 42. A fourth slide groove 431 is disposed on one of the first connecting member 43 and the main rod 61 of the pedal assembly 6, and a second connecting column 611 matched with the fourth slide groove 431 is fixedly disposed on the other, and the fourth slide groove 431 extends in the up-down direction. The second connecting column 611 is located in the fourth slide groove 431 and can be slidably disposed along the length extension direction of the fourth slide groove 431. In this way, when the saddle assembly 4 slides relative to the frame 1 along the length extension direction of the rear frame 13, the pedal assembly 6 is driven to slide relative to the frame 1 in the front-back direction through the cooperation between the fourth slide groove 431 and the second connecting column 611.

The children's toy car also includes a locking mechanism for locking the relative positions of the saddle assembly 4, the handlebar 5, the pedal assembly 6 and the frame 1. The locking mechanism can be arranged between the saddle assembly 4 and the frame 1, or between the handlebar 5 and the frame 1, or between the pedal assembly 6 and the frame 1. The locking mechanism can adopt the structure in the prior art. The saddle assembly 4, the handlebar 5 and the pedal assembly 6 can be locked at multiple positions on the frame 1 by the locking mechanism, as shown in Figures 2 to 4.

In this embodiment, the rear frame 13 extends obliquely from top to bottom and backward, and the first front frame 14 extends obliquely from front to rear and upward. In this way, when the height of the saddle assembly 4 needs to be lowered, the saddle assembly 4 is slid downward along the length extension direction of the rear frame 13, and the saddle assembly 4 moves backward relative to the frame 1 at the same time. The fourth slide groove 431 and the second connecting column 611 are used to drive the pedal assembly 6 to slide backward relative to the frame 1, so that when a child sits on the saddle assembly 4, the child's feet can still step on the pedal rod 62, thereby improving the safety performance of the children's toy car when in use. The first slide groove 631 extends obliquely from front to rear, so that when the pedal assembly 6 slides backward relative to the frame 1, the first connecting rod 71 slides upward relative to the frame 1, and the first shaft 81 moves upward with the first connecting rod 71. When the first shaft 81 moves upward, the second connecting rod 72 rotates relative to the frame 1 around the third shaft 83 through the cooperation between the first shaft 81 and the second slide groove 721, so that the third slide groove 722 drives the second shaft 82 to move downward, and the handlebar 5 slides downward relative to the frame 1 along the second slide sleeve 141, until the height of the saddle assembly 4 is adjusted downward to a relatively low position, and the corresponding position is locked by the locking mechanism.

Conversely, when the height of the saddle assembly 4 needs to be raised, the saddle assembly 4 only needs to slide upward along the rear frame 13 to slide the pedal assembly 6 forward relative to the frame 1 and the handlebar 5 can slide upward along the second sliding sleeve 141 relative to the frame 1.

When the saddle assembly 4 is at the highest position on the frame 1, the second connecting post 611 is located at the lower end of the fourth slide groove 431 in the fourth slide groove 431, the first connecting post 711 is located at the lower end of the first slide groove 631 in the first slide groove 631, the first shaft 81 is located at the lower end of the second slide groove 721 in the second slide groove 721, and the second shaft 82 is located at the rear end of the third slide groove 722 in the third slide groove 722, as shown in FIG2. When the saddle assembly 4 is at the lowest position on the frame 1, the second connecting post 611 is located at the upper end of the fourth slide groove 431 in the fourth slide groove 431, the first connecting post 711 is located at the upper end of the first slide groove 631 in the first slide groove 631, the first shaft 81 is located at the upper end of the second slide groove 721 in the second slide groove 721, and the second shaft 82 is located at the front end of the third slide groove 722 in the third slide groove 722, as shown in FIG4.

The front wheel assembly 2 includes a fork 21 and a front wheel 22 rotatably disposed on the fork 21. The handlebar 5 cooperates with the fork 21, so that when the handlebar 5 slides up and down relative to the frame 1, it also slides up and down relative to the fork 21, and when the handlebar 5 rotates relative to the frame 1 around its own axis, the fork 21 and the front wheel 22 are driven to rotate synchronously relative to the frame 1, so that the children's toy car turns.

In this embodiment, the first front frame 15 extends obliquely from the rear to the front and upwards. This arrangement allows the first front frame 15 and the front wheels 22 to be staggered, thereby reducing the overall structural size of the children's toy car.

The rear wheel assembly 3 is rotatably arranged at the lower part of the rear frame 13. The children's toy car also includes auxiliary wheel assemblies 9, which are respectively arranged on the left and right sides of the rear wheel assembly 3. With the support of the auxiliary wheel assemblies 9, the children's toy car can be prevented from tipping over during driving, and the safety performance of the children's toy car when in use can be improved.

The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
