Description

Technical Field

[0001] The utility model relates to the field of remote control toy cars, in particular to a steering mechanism of a remote control toy car. Background Art

[0002] Toy cars are toys that are deeply loved by people. In order to enable the toy car to turn smoothly during driving, a steering structure needs to be provided between the steering cup on which the wheels are mounted and the suspension.

[0003] Patent No.: CN202322770315.1 discloses a toy car steering mechanism. The toy car steering cup, two adapters, two swing arms and other components increase the stability of the connection and improve the overall strength. It will not be easily deformed or broken when encountering collisions or large bumps, which greatly extends the service life. However, there are still some shortcomings. For example, when the steering mechanism buffers external impact, it uses the deformation of the central sphere to buffer the impact force received by the steering mechanism. The buffering effect is poor, the force unloading means is single, and it cannot effectively buffer the potential energy received by the steering mechanism. After the rotating mechanism is subjected to a large impact force, it is still easy to be damaged. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4In the embodiment of the utility model, a steering mechanism of a remote-controlled toy car includes a steering seat 1. The outer wall of the steering seat 1 is fixedly connected to a connecting plate. The upper end surface of the connecting plate is fixedly connected to a connecting seat 2. The interior of the connecting seat 2 is rotatably connected to a swing arm 3 through a pin shaft. Buffer components 4 are provided on both sides of the swing arm 3. A rotating component 5 is provided inside the swing arm 3. The swing arm 3 is a hollow structure. A through hollow cavity is opened inside the swing arm 3. The design of the hollow cavity can reduce the use of materials for the swing arm 3, thereby reducing costs.

[0020] like Figure 1 and Figure 2 As shown, the buffer assembly 4 includes a connecting column 6 fixedly connected to both sides of the swing arm 3, the outer wall of the connecting column 6 is fixedly connected with a fixing sleeve 7, a damping buffer 8 is fixedly connected between the two fixing sleeves 7, the outer wall of the damping buffer 8 is fixedly connected with a damping pad 9, the outer wall sleeve of the damping buffer 8 is provided with a damping spring 10, and the damping spring 10 is located between the two damping pads 9.

[0021] The working principle of this utility model is:

[0022] During use, the impact force received by the swing arm 3 will be buffered to the buffer assembly 4, and the damping buffer 8, damping pad 9 and damping spring 10 will be deformed. The deformation process is also a process of unloading force, thereby absorbing the potential energy received by the entire buffer steering mechanism and avoiding damage caused by excessive impact force.

[0023] like Figure 3 and Figure 4 As shown, the rotating assembly 5 includes a slot opened on the inner side of the top of the swing arm 3, a connecting block 11 is inserted into the inside of the slot, the bottom of the connecting block 11 is fixedly connected to a limiting screw 12, the limiting screw 12 passes through a through slot 13 opened inside the swing arm 3, the outer wall of the limiting screw 12 is threadedly connected to a limiting nut 14, a rotating groove is opened inside the connecting block 11, a rotating part 15 is rotatably connected inside the rotating groove, a connecting shaft 16 is fixedly connected to the top of the rotating part 15, and a steering wheel 17 is fixedly connected to the outer wall of the connecting shaft 16, an axial hole is opened inside the connecting block 11, the axial hole is communicated with the rotating groove, and the axial hole matches the connecting shaft 16.

[0024] When the steering wheel 17 needs to be replaced later, the limiting nut 14 can be loosened and the connecting block 11 can be pulled out from the inside of the slot, so that the steering wheel 17 can be removed from the swing arm and replaced with a new steering wheel 17. This prevents the steering wheel 17 from being severely worn and unusable after long-term use. The steering wheel 17 can rotate 360 degrees through the cooperation of the rotating groove and the rotating part 15, thereby improving the overall flexibility of the steering mechanism.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
