[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] Models and model toys are increasingly embodying high-tech interactivity, with new model products focusing on safety, entertainment, and education. Demo prototyping facilitates product development, adjustments, and functional improvements, enabling products to be designed with visualization and interactive demonstrations. This application proposes a fastening and adjustment structure for a demo steering wheel to improve the steering wheel's adjustment flexibility and user experience, thereby meeting user needs.

[0024] Please see Figure 1 The fastening and adjustment mechanism 10 includes a steering wheel 1, an adjustment shaft 2, a fixed shaft 3, and a base 4; the adjustment shaft 2 is hinged to the fixed shaft 3, the end of the adjustment shaft 2 away from the hinge point is connected to the steering wheel, and the end of the fixed shaft 3 away from the hinge point is connected to the base 4.

[0025] Please see Figure 2 The end of the adjusting shaft 2 that is hinged to the fixed shaft 3 is constructed as a semi-circular protrusion 21, with a through hole I 211 at the center. The end of the fixed shaft 3 is constructed as a contoured groove 31 that matches the semi-circular protrusion 21 of the adjusting shaft 2, with a through hole II 311 on the side wall of the contoured groove 31 corresponding to the through hole I 211. This construction facilitates the pivot 22 to pass through the through hole II 311 and the through hole I 211, assembling the adjusting shaft 2 and the fixed shaft 3 together, and ensuring that the semi-circular protrusion 21 of the adjusting shaft 2 slides smoothly in the contoured groove 31 of the fixed shaft 3.

[0026] One end of the pivot 22 is provided with a threaded section 221, and the other end is provided with a handle 222. After the adjusting shaft 2 and the fixed shaft 3 are assembled, a fastening nut is provided on the threaded section 221 of the pivot 22. The nut is tightened or loosened in conjunction with the handle 222, thereby realizing the fastening adjustment of the adjusting shaft 2 and the fixed shaft 3.

[0027] In some embodiments, one of the through holes II 311 is configured as a threaded hole 311a that matches the threaded section 221 of the pivot 22, thereby facilitating the adjustment of the pivot 22 and saving parts.

[0028] In some embodiments, the surface 32 of the fixed shaft 3 having the through hole II 311 can be integrally formed with the fixed shaft 3, or it can extend out of the fixed shaft 3 to form a bracket. This configuration can improve the adjustment flexibility of the handle 222 of the pivot 22.

[0029] In some embodiments, one side of the semi-circular protrusion 21 of the adjusting shaft 2 is configured as a groove 212 that can accommodate the elastic component 23. A receiving cavity 213 is formed in the groove 212 along the axis 24 of the adjusting shaft 2. The elastic component 23 includes an elastic element 231 and an adjusting element 232. One end of the elastic element 231 is housed in the receiving cavity 213, and the other end of the elastic element 231 is connected to the adjusting element 232.

[0030] The semi-circular protrusion 21 of the adjusting shaft 2 also includes a protrusion 214 that mates with the groove 212 to form the semi-circular protrusion 21. The protrusion 214 along the axis 24 of the adjusting shaft 2 is configured as a stepped hole 215, and the adjusting member 232 matches the stepped hole 215.

[0031] Please see Figure 3The fixed shaft 3 has a groove 312 on one side of the contour groove 31 along the axis 33 of the fixed shaft 3. The fixed shaft 3 also includes a fixed plate 34 with a continuous slot 341 on its inner side. The slot 341 can engage with the adjusting member 232 for assembly. The adjusting member 232 of the elastic component 23 extends out of the stepped hole 215 fixed on the protrusion 214 of the adjusting shaft 2 and engages with the slot 341 fixed on the fixed plate 34 of the fixed shaft 3 to realize the angle adjustment of the adjusting shaft 2 and the fixed shaft 3.

[0032] In some embodiments, the front end of the adjusting member 232 is provided with teeth, and the inner side of the contour groove 31 of the fixed shaft 3 is provided with a tooth groove that can mesh with the teeth. It is known that the tooth groove is provided in the contour groove 31 along the arc-shaped movement trajectory of the adjusting member 232.

[0033] The fastening and adjustment mechanism 10 is used for steering wheel angle adjustment. It has a simple structure and achieves both fastening and angle adjustment functions to meet user needs.

[0034] This application also proposes a grid-type LED unit module; please refer to [link / reference needed]. Figure 4 The grid-type LED unit module 20 includes a grid mesh 201 with grid holes, and LED beads 202 are disposed in the grid holes. A driving unit 203 for driving the LED beads 202 to work normally is disposed on the back of the grid mesh 201.

[0035] Please see Figure 5 The grid holes of the grid 201 serve as reflective holes, reflecting the light beam emitted by the LED beads 202. The light beam is emitted from the central area or reflected from the edge area. It can be seen that by setting the curvature of the sidewall of the grid hole, the emission direction of the light beam can be adjusted, that is, the light beam is focused as much as possible to form a relatively high number of parallel light beams.

[0036] An optical element 204, including a polarizing filter and a focusing optical element, is disposed above the grid holes of the grille 201. In this configuration, the optical element 204 on the grid holes converts the light beam from the LED beads 202 to create a changing color effect. When applied to a steering wheel or car model in the above embodiments, this enhances the design, enriches the product's color and rhythm, highlights design quality, and improves brand value.
