[0028] Example 1

[0029] A light-up sports skateboard 100 has been unveiled. The light-up sports skateboard 100 features edge decorative lights for roller skating and can be mounted on two roller brackets, each with a pair or one roller.

[0030] Please see Figure 1 , Figure 2 and Figure 3 The luminous motion skateboard 100 includes a core plate 11, an outer ring 12, a strip light-emitting body 21, a power control unit 22, and a wire 23.

[0031] Both the core board 11 and the outer ring 12 are made of bamboo-wood-fiberglass composite material, prepared by a layered pressing process. The formula can be found in the embodiment of patent CN102416253A. The plastic elastomer 13 is a thermoplastic polyurethane (TPU) component. The strip light emitter 21 is a flexible LED light strip, with LED chips or LED beads mounted on both sides.

[0032] The two ends of the core plate portion 11 in the longitudinal direction narrow and bend downwards, and the top surface of the middle part of the core plate portion 11 in the longitudinal direction is grooved. Thus, the core plate portion 11 is saddle-shaped, forming a wider first assembly area 103 at the front and a wider second assembly area 104 at the rear. Roller brackets are installed on portions of the bottom surface 102 of the core plate portion 11 corresponding to the first assembly area 103 and the second assembly area, respectively. The top surface 101 of the core plate portion 11 is used to bear the load and can be used by the user for footing, lying prone, sitting, or elbow support. This structure prevents the user from slipping off the luminous motion skateboard 100, reduces interference between the user and the front and rear ends, and cushions impacts through edge deformation.

[0033] The core board section 11 has a central groove at its center for mounting the power control unit 22. The core board section 11 also has a wire groove for mounting wires 23. The central groove and wire groove are not shown in the attached drawings.

[0034] The outer ring portion 12 is configured as a closed annular member, surrounding the periphery of the core plate portion 11, and the gap between the outer ring portion 12 and the core plate portion 11 forms an annular through hole 10a. The annular through hole 10a completely isolates the outer ring portion 11 from the core plate portion 12. That is, the outer ring portion 11 and the core plate portion 12 do not directly contact each other.

[0035] The annular through hole 10a can be regarded as a long strip-shaped through hole with its ends connected, filled with transparent plastic elastomer 13.

[0036] The strip-shaped light-emitting element 21 is sealed inside the plastic elastomer 13, laid flat at half the height of the annular through hole 10a, surrounds the core plate part 11, and is electrically connected to the power control part 22 through the wire 23.

[0037] The wire 23 is located in the wire groove of the core plate 11. One end is welded to the electrode terminal of the strip light-emitting body 21, and the other end is welded to the power supply terminal of the power control unit 22.

[0038] The power control unit 22 is located in the central slot of the core board unit 11 and is configured as a conventional embedded computer system. It includes electronic components such as a circuit board, processor chip, storage chip, wireless communication chip, rechargeable battery, power circuit, and vibration sensor.

[0039] The manufacturing process of the luminous sports skateboard 100 includes the following steps:

[0040] S110. Prepare the curing mold, assembly mold, core board 11, outer ring 12, strip light-emitting body 21, power supply and control unit 22 and wire 23, and weld one end of wire 23 to strip light-emitting body 21;

[0041] S120. In a horizontally set curing mold, inject 50% of the predetermined amount of plastic precursor, spread the strip light-emitting body 21 on the leveled plastic precursor, inject the remaining plastic precursor, and allow the plastic precursor to level, degas and cure.

[0042] S130. Demolding to obtain a plastic elastomer 13 with a strip light-emitting body 21 encapsulated inside. Cleaning, roughening and applying adhesive to the non-transparent surface (i.e. the bonding surface) of the plastic elastomer 13.

[0043] S140. Position the core plate portion 11 and the outer ring portion 12 in the assembly mold to form an annular through hole 10a. Embed the plastic elastomer 13 into the annular through hole 10a and demold after the adhesive has cured.

[0044] S150. The power control unit 22 is mounted on the core board 11, and the other end of the wire 23 is soldered. Then, the center groove and wire groove of the core board 11 are covered with a skin.

[0045] The luminous sports skateboard 100 includes a core plate portion 11, an outer ring portion 12, a strip-shaped light-emitting element 21, and a power control unit 22. An annular through-hole is formed between the outer ring portion 11 and the core plate portion 12. The strip-shaped light-emitting element 21 is sealed within the annular through-hole by a transparent plastic elastomer 13. The power control unit 22 is embedded in the core plate portion 11. Thus, the plastic elastomer 13 acts as a lens for the strip-shaped light-emitting element 21, allowing the light from the strip-shaped light-emitting element 21 to be emitted uniformly, thereby improving the lighting effect. In addition, the saddle shape of the luminous sports skateboard 100 and the plastic elastomer 13 located around its perimeter can cushion impacts.

[0046] Example 2

[0047] The 200 light-up sports skateboard has been unveiled.

[0048] Compared to the aforementioned illuminated sports skateboard 100, the illuminated sports skateboard 200 has the following improvements.

[0049] Please see Figure 4 The main body of the luminous motion skateboard 200 is a rectangular flat plate with several strip-shaped through holes 10b along its edge. All the strip-shaped through holes 10b are arranged in a discontinuous ring. The portion of the main body located within this ring is called the core plate portion 11'. The portion of the main body located outside this ring is called the outer ring portion 12'. The various breaks in this ring are called connecting portions 15', and their circumferential lengths are basically consistent. That is, the core plate portion 11' and the outer ring portion 12' are locally and directly integrally connected through the connecting portions 15', with the gap between them including several strip-shaped through holes 10b.

[0050] Please see Figure 5 The plastic elastomer 13' has two light-transmitting surfaces: one on the top surface 101 has an outwardly convex arc-shaped cross-section, and the other on the bottom surface 102 has an inwardly concave arc-shaped cross-section.

[0051] The strip-shaped light emitter 21' is a rigid light guide plate that does not contact the sidewall of the strip-shaped through hole 10b, and has LED beads at one end or on one side. Figure 5 (Not shown), light is emitted evenly from two surfaces. The light guide plate and LED light source are commonly used as backlights for LCD displays; their specific structure does not need to be described in detail.

[0052] The luminous motion skateboard 200 also includes two transparent fiberglass cloth composite layers 14. One transparent fiberglass cloth composite layer 14 covers the top surface 101, and the other transparent fiberglass cloth composite layer 14 covers the bottom surface 102. Specifically, the opening edges of the strip-shaped through-hole 10b and the light-transmitting surface of the plastic elastomer 13 are both adhered to or even embedded in the transparent fiberglass cloth composite layer 14.

[0053] The manufacturing process of the luminous sports skateboard 200 includes the following steps:

[0054] S210. Prepare a potting mold, a skateboard body, a power control unit 22, several strip light emitters 21' and several wires 23, and solder one end of all wires 23 to the power control unit 22;

[0055] S220. Install the wire 23 and the power control unit 22 into the core plate part 11' of the skateboard body;

[0056] S230. Position the slide body in a horizontally set potting mold;

[0057] S240. Inject 50% of the predetermined amount of plastic precursor into each strip-shaped through hole 10b, spread the strip-shaped light-emitting body 21' on the leveled plastic precursor, inject the remaining plastic precursor, and make sure that the LED lamp bead terminals of the strip-shaped light-emitting body 21' are exposed and extend into the corresponding wire groove, and allow the plastic precursor to degas and cure.

[0058] S250. Demolding, welding the LED terminal of the strip light-emitting body 21' to the other end of the wire 23, covering and sealing the power control part 22 and the wire 23 with a skin, and covering the strip through hole 10b and the plastic elastomer 13 with a transparent composite layer of fiberglass cloth 14.

[0059] The potting mold has multiple protrusions corresponding to the strip-shaped through 10b. The edge surface of the strip-shaped through 10b does not wet and spread the plastic precursor, so the bottom surface of the plastic elastomer 13' is concave and the top surface is convex.

[0060] The luminous sports skateboard 200 has the following technical advantages:

[0061] 1) The main body of the luminous motion skateboard 200 is integrally molded, and the top and bottom surfaces are covered with a transparent composite layer 14 of fiberglass cloth, which has high structural strength and simplified manufacturing process;

[0062] 2) Install a strip light source 21' in each strip through hole 10b. The power control unit may be equipped with acceleration and attitude sensors, so that the strip light sources 21' at the four corners can be used as turn signals and brake lights.

[0063] 3) The curved light-transmitting surface of the plastic elastomer 13 can increase the emission angle of the top light and reduce the emission angle of the bottom light, thus further improving the lighting effect.

[0064] In another approximate embodiment, the luminous motion skateboard 200 is used for ice skating and is mounted on a skating frame. The bottom of the skating frame is provided with a pair of slide bars, and the power control unit is close to the bottom surface of the core plate 11' and fixed in the skating frame.

[0065] In other embodiments, both the core plate body and the outer ring are carbon fiber composite material components. For specific components and molding processes, please refer to the embodiments of patent CN118124236A / 2024.

[0066] In other embodiments, the plastic elastomer can be extruded using DuPont's TPEE Hytrel HTR series products as raw materials, and can be cross-linked and cured with polysiloxane as the main component.

[0067] The above embodiments, application examples, and technical analyses are intended to introduce the technical concept and features of this utility model, enabling those skilled in the art to implement the technical solution of this utility model, and do not constitute any limitation on the protection scope of this utility model. Simple modifications and equivalent transformations to the above embodiments are all within the protection scope of this utility model.
