Technical Field

[0001] The invention relates to the technical field of toy vehicle manufacturing, in particular to a novel crawler vehicle chassis. Background Art

[0002] As people's living standards continue to improve, their attention to entertainment is also increasing. Parents who can afford it usually buy cars that can carry people.

[0003] Most toy cars under the existing technical level are made by simplifying the structure of real vehicles, and lack applicable considerations in some structures, especially in the design of chassis structure.

[0004] The existing vehicle chassis structure lacks compactness. In the process of providing support for the crawler tracks, it is difficult to ensure the stability of the crawler tracks, which makes the crawler tracks prone to loosening, thereby affecting the normal movement of the crawler tracks. In addition, in order to save manufacturing costs, the existing vehicles have simplified the vehicle structure and usually only use one motor to drive the two crawlers. However, one motor drives the two crawlers at the same time, which will bring inconvenience to driving and steering in actual driving operations. In particular, for those who have no driving experience, the lack of coordination between the two crawlers can easily cause rollover accidents in emergency situations, thereby causing serious physical injuries. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the crawler structure of the vehicle is not compact enough, resulting in a lack of stability of the crawler, and to propose a new crawler vehicle chassis.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Preferably, the extension bracket is arranged at an angle, and the extension bracket is L-shaped, the branch rod is arranged horizontally with the secondary horizontal axis, and the four secondary rollers correspond to each other with the free end of the extension bracket as the center.

[0011] Preferably, the primary roller, the tensioning roller and the driving roller are flush.

[0012] Preferably, the supporting mechanism is located obliquely below the primary roller.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The present invention connects the tensioning roller, the primary roller and the driving roller at the same height on the front shaping frame, the primary bracket, the secondary bracket and the rear shaping frame respectively, so as to provide an upward supporting force for the crawler track; at the same time, the supporting mechanism is obliquely connected to both ends of the front shaping frame, the primary bracket and the secondary bracket, and the secondary connecting rod is correspondingly connected to the obliquely arranged extension bracket, and a plurality of secondary rollers are uniformly arranged at a horizontal position lower than the primary roller to provide a downward squeezing force for the crawler track, so as to provide tension support for the crawler track and ensure that the crawler track is always in a taut state.

[0015] 2. The present invention installs a primary motor and a secondary motor in the rear shaping frame correspondingly, and uses the primary motor and the secondary motor to drive two active rollers respectively, that is, a dual power flow driving scheme is adopted, and the two motors drive the left and right tracks through two active rollers. The driving power is divided into driving power and steering power, and the driving power and steering power can be set separately. The driving power is set to 75%, which is controlled by the accelerator pedal, and the steering power is set to 25%, which is controlled by the steering wheel; the steering voltage signal output by the steering wheel is provided to the motor controller, so that the left and right motors produce positive and negative speed changes. In this way, the vehicle can turn in place at zero speed, and the steering diameter is equal to the width of the vehicle body. It is very flexible to operate in a narrow space, which is convenient for driving operation and has extremely high safety guarantee.

[0016] In summary, the present invention adopts a base composed of a front shaping frame, a primary bracket, a secondary bracket and a rear shaping frame, and respectively arranges a tensioning roller, a primary roller and an active roller on the same horizontal line of the front shaping frame, the primary bracket, the secondary bracket and the rear shaping frame to provide an upward supporting force for the crawler track; a supporting mechanism is horizontally arranged at a lower position of the front shaping frame, the primary bracket and the secondary bracket to rotate and squeeze the crawler track to ensure smooth rotation of the crawler track; two crawlers are respectively driven by separately arranged primary motors and secondary motors to facilitate accurate and rapid operation of the crawler track, which is convenient for operation, and the safety of the operation process is ensured by improving the stability of the chassis and crawler track of the crawler vehicle and the convenience of operation.
