Description

a toy car

technical field

The utility model relates to a toy car, in particular to a toy car which can imitate the crawling action of animals.

Background technique

Toy cars are a kind of children's toy that most children, especially boys like very much. Early toy cars generally imitated the shape of real cars with free-rotating wheels, relying on external forces to push forward or slide from high to low, and the fun was basically limited to the realistic and beautiful appearance.

Later, a toy car driven by a spring assembly appeared. Due to the addition of a spring assembly that can store power and release automatically, the toy car can automatically travel within a certain distance, which improves the fun of the toy car. But even the toy cars driven by small DC motors that occurred later were only limited to the improvement and improvement of driving force, while ignoring the further improvement of interest.

Utility model content

In order to solve the above-mentioned problems existing in the toy car in the prior art, the purpose of the utility model is to provide a toy car that can imitate the crawling action of animals.

In order to achieve the above object, the utility model provides a toy car, comprising:

chassis;

a driving wheel, the driving wheel includes a driving wheel shaft and driving wheel discs arranged on both sides of the driving wheel shaft, and the driving wheel shaft is rotatably connected to the chassis;

a driven wheel, the driven wheel includes a driven wheel shaft and driven wheel discs arranged on both sides of the driven wheel shaft, the driven wheel shaft is rotatably connected to the chassis; and

A power device arranged on the chassis and used to drive the rotation of the driving wheel shaft;

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing.

As shown in Fig. 1 to Fig. 3, the toy car imitating the little sea turtle of one embodiment of the utility model comprises: chassis 3; The driving wheel discs 51 on both sides of the driving wheel shaft, the driving wheel shaft is rotatably connected to the chassis 3;

The driven wheel 5, the driven wheel 5 includes a driven wheel shaft 8 and driven wheel discs 50 arranged on both sides of the driven wheel shaft 8, the driven wheel shaft 8 is rotatably connected to the chassis 3; and

A power device 7 arranged on the chassis 3 for driving the rotation of the driving wheel shaft;

Both the driving wheel 51 and the driving wheel shaft and the driven wheel 50 and the driven wheel shaft 8 are connected eccentrically. The eccentric connection can make the toy car fluctuate up and down when it is moving, combined with the realistic animal appearance, the utility model is more interesting than the transmission toy car.

The power device in this embodiment is a clockwork assembly 7, and the rotation of the dowel 10 drives the spring to store energy. As shown in Figures 2 and 3, the chassis 3 is provided with a back shell 2 protruding upwards to imitate a small turtle, a butterfly-shaped anti-skid head 11 is arranged on the top of the dowel bar 10, and a butterfly-shaped anti-skid head 11 is arranged on the top of the back shell 2. Knob 6 , the anti-slip head 11 extends into the connection port 13 of the knob 6 located in the back shell 2 , the connection port 13 is in the shape of a gear, and can mesh with the butterfly-shaped anti-slip head 11 . When in use, only need to rotate the knob 6 to store energy for the mainspring through the dowel 10 . Of course, the power unit in this embodiment can be any power unit that may be used in existing toy cars. In addition, in order to make the animal toy car more vivid and vivid, different power devices can be selected according to different animal shapes, so that the speed of the toy car can be faster or slower. For example, the turtle-shaped toy car of this embodiment adopts a clockwork assembly with less potential energy, a gear set with a larger reduction ratio, or a motor with a lower rotating speed, etc., so that the tortoise toy car can be advanced at a relatively slow speed. In addition, the eccentrically connected wheels make the turtle toy car rise and fall, so that children can enhance their cognition of the shape and speed of small animals while playing.

As shown in FIGS. 1 to 3 , the animal toy vehicle of the present utility model can also include a head 1 . The inner wall of one end of the back shell 2 corresponding to the driven wheel 5 is pivotally provided with a transmission arm 17 through a support shaft 14, and one end of the transmission arm 17 is connected to the head 1 through the hole 21 provided at the front end of the back shell 2, The other end bends down and extends to contact with the surface of an eccentric cam 9 arranged in the middle of the driven wheel shaft 8 . Fig. 4 is an enlarged view of the eccentric cam 9, and the joint hole 91 of the driven wheel shaft is not located at the center of the circle, so the transmission arm 17 can be driven to move back and forth with the rotation of the eccentric cam 9 when rotating. When the animal toy car is moving, the driven wheel shaft 8 rotates to drive the eccentric cam 9 to rotate to drive the transmission arm 17 to move back and forth, and then the transmission arm 17 rotates around the support shaft 14 to drive the head 1 to move, and the weight of the head 1 can be lifted. Therefore, the whole process will be the image of the head moving up and down, which vividly imitates the naive appearance of the little turtle when it is crawling. In order to make the movement of the head 1 more coherent, a mounting plate 16 is disposed under the support shaft 14 , and a tension spring 15 is disposed between the inner side of the downwardly bending and extending transmission arm 17 and the mounting plate 16 .

When this part is installed, the supporting shaft 14 and the transmission arm 17 can be installed and pivoted on the back shell 2 first, and then the mounting plate 16 can be fixed. The mounting plate 16 can play the role of reinforcing the support shaft 14 on the one hand, and can also serve as a connection point of the tension spring 15 in addition.

The position corresponding to the drive wheel 4 on the chassis 3 may also include a tail part 19, and at least one small animal model may be connected end to end to the tail part 19 in turn. FIG. 6 is a schematic structural view of the small animal model 30 . Figure 5 shows two small animal models 30, 31 connected end to end in turn. The head of the small animal model 30 is provided with a connecting ring 302 , and the connecting ring 302 can be connected with the connecting rod 191 provided on the tail 19 of the chassis 2 . Similarly, the tail 301 of the small animal model 30 is also provided with a connecting rod that can be connected with the small animal model 31 . The small animal model may not have a power plant, but may have wheel components that are conducive to moving forward. The connection mode of the end-to-end connection can also be a variety of connection modes such as socketing, hooking or snapping.

The big animal toy car with power device can drag several small animal models forward, not only cute, but also full of family affection, which can promote parent-child relationship.

The above is the preferred implementation of the present utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, some modifications can also be made on the basis of the above disclosed embodiments. Improvement and retouching, these improvements and retouching are also regarded as the protection scope of the present utility model. For example, in the illustrations of the two above-mentioned embodiments, all the implementations in which the appearance is a small sea turtle are given, but obviously, other small animals are also applicable to the present utility model.
