Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in one or more embodiments or examples.
[0041] With reference to Figure 4 and Figure 5 According to the first embodiment of the chassis structure of the present application, it comprises a main body 100, lamp beads 200 and a light folding part 300.
[0042] The main body 100 has a front wheel 110 and a rear wheel 120;
[0043] The lamp beads 200 are arranged on the main body 100 and located between the front wheel 110 and the rear wheel 120, and the lamp beads 200 are provided with at least two;
[0044] The light folding part 300 is detachably connected with the main body 100 and located on one side of the lamp beads 200, and at least two mounting positions 310 are formed on the side of the light folding part 300 close to the lamp beads 200, each mounting position 310 contains at least one lamp bead 200; a plurality of light collecting surfaces 320 are formed on the side of the light folding part 300 away from the lamp beads 200, a light collecting position 330 is formed between the plurality of light collecting surfaces 320, and the light collecting surfaces 320 are directed towards the light collecting position 330; and a light scattering surface 340 is formed on the side of the light folding part 300 close to the front wheel 110 and the rear wheel 120.
[0045] It can be understood that the light folding part 300 is of light-transmitting material, the lamp beads 200 located at the mounting positions 310 can emit light, the light emitted by the lamp beads 200 can pass through the light folding part 300 and be emitted from the light collecting surfaces 320 and the light scattering surface 340. Since the light folding part 300 is detachably connected with the main body 100, the color of the light folding part 300 can be changed by replacing it, so that the light folding part 300 emits different colors, thereby the color of the light emitted by the chassis structure can be changed without replacing the lamp beads 200, and therefore when model cars with different light colors need to be produced, only the light folding part 300 needs to be replaced, without installing lamp beads 200 of different colors according to each model car, so as to reduce the production cost.
[0046] For example, the light color of the lamp beads 200 is white, when the light folding part 300 is red, the light emitted by the lamp beads 200 becomes red through the light folding part 300, so that the chassis structure forms a red light effect.
[0047] It should be understood that the lamp bead 200 is generally welded on the circuit board 140 of the main body 100 and is not easy to disassemble. The light color can be adjusted by replacing and disassembling the light folding part 300, which is relatively simple. In the production process of the chassis structure of the present application, the main body 100 with the lamp bead 200 mounted thereon can be produced first, and then the corresponding light folding part 300 can be installed according to the light color required by the current chassis structure. Therefore, it is not necessary to install lamp beads 200 of different colors on the main body 100. The production process is more simple, the main body 100 and the lamp bead 200 can be used for various vehicle models, and the production process and production cost can be reduced. Moreover, the light folding part 300 is easy to disassemble, so that the user can replace the light folding part 300 of different colors in the later period according to his own needs to make the chassis structure emit light of different colors, thereby improving the playability.
[0048] It can also be understood that every two adjacent light collecting surfaces 320 form a group, the two light collecting surfaces 320 in the same group are oppositely inclined and inclined towards each other, so that a notch is formed between the two light collecting surfaces 320, that is, a light collecting position 330 is formed between the two light collecting surfaces 320. The light collecting surface 320 can emit light towards the light collecting position 330. Therefore, the light emitted by the two light collecting surfaces 320 will converge at the light collecting position 330, so as to improve the light at the light collecting position 330 and improve the visual effect of the light.
[0049] It can also be understood that one of the light scattering surfaces 340 is directed towards the front wheel 110, and one of the light scattering surfaces 340 is directed towards the rear wheel 120. Therefore, the light emitted by the light scattering surface 340 can irradiate the front wheel 110 and the rear wheel 120, further improving the visual effect of the light.
[0050] Specifically, the light scattering surface 340 can be frosted to make the light emitted by the light scattering surface 340 more soft,
[0051] Referring to Figure 4 and Figure 5 According to some embodiments of the present application, the mounting position 310 is formed with a first light entrance surface corresponding to the light collecting surface 320.
[0052] It can be understood that the first light entrance surface is parallel to the light collecting surface 320 or has a small inclination angle. Therefore, the light emitted by the lamp bead 200 can better reach the light collecting surface 320 through the first light entrance surface and be emitted through the light collecting surface 320.
[0053] Referring to Figure 4 and Figure 5 According to some embodiments of the present application, the mounting position 310 is formed with a second light entrance surface corresponding to the light scattering surface 340.
[0054] It can be understood that the first light-in surface is parallel to the light-collecting surface 320 or has a small inclination angle, so that the light emitted by the lamp bead 200 can reach the light-collecting surface 320 well through the first light-in surface and be emitted through the light-collecting surface 320.
[0055] With reference to Figure 4 and Figure 5 According to some embodiments of the present application, the mounting position 310 is a groove 350 formed on one side of the light-refracting portion 300.
[0056] It can be understood that the groove 350 is formed on the side of the light-refracting portion 300 close to the main body 100, and the groove 350 corresponds to the mounting position 310. During the installation of the light-refracting portion 300 on the main body 100, the groove 350 corresponds to the lamp bead 200 on the main body 100, so that after the light-refracting portion 300 is connected to the main body 100, the lamp bead 200 is located in the groove 350. By forming the groove 350 to accommodate the lamp bead 200, the light emitted by the lamp bead 200 can be emitted through the light-shielding plate as much as possible.
[0057] With reference to Figure 4 and Figure 5 According to some embodiments of the present application, the illumination color of the lamp bead 200 is white.
[0058] It can be understood that the illumination color of the lamp bead 200 is set to white, so that the color of the light-refracting portion 300 is the color of the light emitted by the light-refracting portion 300. In this way, the color of the light-refracting portion 300 can be selected according to the color of the light required by the chassis structure. In addition, part of the light emitted by the lamp bead 200 will not be emitted through the light-refracting portion 300. By setting the illumination color of the lamp bead 200 to white, the interference of the lamp bead 200 on the color emitted by the light-refracting portion 300 can be reduced.
[0059] In other embodiments, the illumination color of the lamp bead 200 can also be other colors, such as red, green, blue, etc.
[0060] With reference to Figure 4 and Figure 5 According to some embodiments of the present application, the light-refracting portion 300 is bonded, clamped or screw-connected to the main body 100.
[0061] It can be understood that the light-refracting portion 300 is bonded, clamped or screw-connected to the main body 100, so that the light-refracting portion 300 can be easily disassembled relative to the main body 100. This can improve the production efficiency and facilitate the subsequent disassembly of the user.
[0062] With reference to Figure 4 and Figure 5According to some embodiments of the present application, the main body 100 comprises a chassis 130 and a circuit board 140, the circuit board 140 is arranged at the upper end of the chassis 130, and the two sides of the circuit board 140 in the width direction protrude from the chassis 130 to form a convex edge 143, the lamp beads 200 are arranged at the lower end of the convex edge 143, and the circuit board 140 is electrically connected with the lamp beads 200.
[0063] It can be understood that the circuit board 140 is arranged to be larger in the width direction, so that the size of the circuit board 140 in the width direction is larger than the size of the middle part of the chassis 130 in the width direction, so that the two sides of the circuit board 140 in the width direction protrude from the chassis 130, the part of the circuit board 140 protruding from the chassis 130 forms a convex edge 143, the convex edge 143 is located between the front wheels 110 and the rear wheels 120, the lamp beads 200 are arranged at the lower end of the convex edge 143, and the light folding part 300 is also arranged at the lower end of the convex edge 143. The lamp beads 200 emit light downward, and thus the light is shielded upward by the convex edge 143, so that the light of the lamp beads 200 can be emitted downward as much as possible.
[0064] For example, the light emitted by the lamp beads 200 is downward, and then part of the light is focused below the chassis structure by the light focusing surface 320 of the light folding part 300, and part of the light is emitted onto the front wheels 110 and the rear wheels 120 by the light diffusing surface 340 of the light folding part 300. When the model car with the chassis structure of the present application is stationary, the light has a display effect similar to a welcome light. When the model car with the chassis structure of the present application is running, the light focusing surface 320 can improve the light of the lamp beads 200 reflected on the track, so that the model car has a chasing light effect when running, and part of the light hits the front wheels 110 and the rear wheels 120. The rotation of the front wheels 110 and the rear wheels 120 cooperates with the light to make the running of the front wheels 110 and the rear wheels 120 more dynamic.

[0066] Referring to Figure 4 and Figure 5 According to some embodiments of the present application, the main body 100 is provided with two groups of front wheels 110 and rear wheels 120, and the two groups of front wheels 110 and rear wheels 120 are distributed along the width direction of the main body 100; the light folding part 300 is provided with two, and the two light folding parts 300 are respectively located on the two sides of the width direction of the main body 100, and each light folding part 300 corresponds to a group of front wheels 110 and rear wheels 120.
[0067] It can be understood that the chassis structure is applied to a model car of a racing style, generally has two groups of front wheels 110 and rear wheels 120, and it should be understood that a light folding part 300 is correspondingly arranged between each group of front wheels 110 and rear wheels 120, so that both sides of the chassis structure can form focused light through the light collecting surface 320, and the light is reflected on both groups of front wheels 110 and rear wheels 120.

[0069] It can be understood that the light folding part 300 is roughly in a W-shaped structure, the side of the light folding part 300 connected to the main body 100, i.e. the upper side of the light folding part 300, forms two grooves 350, i.e. mounting positions 310, the main body 100 is provided with two lamp beads 200 corresponding to one light folding part 300, and each lamp bead 200 corresponds to one groove 350. The side of the light folding part 300 away from the lamp bead 200, i.e. the lower side of the light folding part 300, forms a gap 360, i.e. a light collecting position 330, and one light collecting position 330 corresponds to two adjacent and oppositely inclined light collecting surfaces 320. The two sides of the light folding part 300 close to the front wheels 110 and the rear wheels 120, i.e. the front and rear sides of the light folding part 300, form light scattering surfaces 340. Thus, the light folding part 300 of the present application has a simple structure.
