Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

By providing a multi-axis suspension axle assembly, the embodiment of the present invention solves the situation that with the continuous improvement of people's living standards, the toy car is no longer limited to simply imitating the appearance of the real vehicle and cannot drive automatically, and the toy car The age level of the distribution of players has gradually expanded, and at the same time, the sense of experience required by simulated vehicles has also increased. Therefore, most of the existing simulated vehicles, such as simulated trailers, not only drive on flat roads, but also drive in some fields, Complex roads such as mud depressions are used to imitate the functions of real trailers, and the size and height of simulated trailers are ultimately much lower than those of real trailers. It also drives smoothly by virtue of its own height and power, so the axles at the bottom of the simulated trailer are easily stuck or worn by roadblocks, which greatly reduces the service life and cost of the simulated trailer.

The technical solution in the embodiment of the present invention is to solve the above technical problem, and the general idea is as follows: the height of the multi-axis suspension axle can be adjusted as a whole by setting the adjustment component, and the normal running of the wheel 1 is not affected. Compared with most of the existing simulations Suspension vehicles, when encountering speed bumps or soil slopes in the wild, the height of the axles can be adjusted according to the use situation, so that the vehicle can pass safely.

In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific embodiments.

The connecting frame 4 can be disassembled.

As a specific embodiment of the present invention, the cargo compartment 10 is made of PA plastic.

Because PA plastic has the characteristics of low melting point and easy regeneration, the cargo bin 10 is made of PA plastic, which can be recycled and reused to make cargo bins 10 of different shapes. At the same time, the weight of the cargo bin 10 using PA plastic is relatively light. Thus, the pressure on the connecting frame 4 and the connecting shaft 2 is reduced.

Working principle: When the vehicle encounters a speed bump on the road or encounters a soil slope in the field, the motor 7 fixedly connected to the outer side of the middle of the connecting frame 4 is activated, and the output shaft of the motor 7 passes through the side wall of the connecting frame 4 to drive the placement slot. The No. 3 gear 6 in the middle part of the slot 41 rotates, the No. 3 gear 6 in the middle part of the slot 41 drives the No. 2 gear 5 on both sides to rotate, and the No. 3 gear 6 in the middle part of the slot 41 is placed on both sides of the No. 2 gear 5 The connecting shaft 2 fixedly connected inside rotates at the same time. When the two connecting shafts 2 in the middle part rotate, the second gear 5 fixedly connected with it simultaneously drives the two third gears 6 meshed with it and away from the motor 7 to rotate, and the gears 6 away from the motor 7 rotate. When the two No. 3 gears 6 rotate, they drive the No. 2 gears 5 at the most two ends to rotate, and the No. 2 gears 5 at the most ends rotate to drive the connecting shafts 2 at the two ends to rotate, so that when the motor 7 is turned on, the four connecting shafts rotate. 2 rotate at the same time, when the four connecting shafts 2 rotate, the gears at both ends of the connecting shafts 2 will drive the four connecting shafts 2 at the same time under the action of the teeth opened on the side wall of the sliding groove 31 that match the shape and size of the No. 1 gear 21. Move up and down in the sliding groove 31, so as to adjust the height of the connecting shaft 2 and the ground, so that it passes through the speed bump or soil slope, when the connecting shaft 2 moves up and down, the connecting frame 4 will follow it to move up and down synchronously, and the connecting frame 4 normally goes up and down When moving, the rectangular rod 8 slides up and down in the limit slot 81, thereby providing a certain limit for the fixed rod 3, so that the fixed rod 3 will not rotate, so as to ensure that the No. 1 gear 21 can work normally in the fixed rod 3 on the one hand. Moving up and down, on the other hand, ensures the normal operation of the wheel 1; the four connecting shafts 2 can move up and down to realize the overall distance adjustment of the multi-axis axles. When encountering high roadblocks, the multi-axis axles are raised, and the multi-axis axles are lowered when passing the roadblocks. Multi-axle axle, the multi-axle axle can realize distance adjustment without affecting the normal operation of the wheel 1, so that the probability of passing on the complex road is increased, and the probability of the multi-axle axle being damaged by roadblocks is reduced.
