Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0029] This utility model embodiment provides a self-generating luminous tire. Figure 1 This is a schematic diagram of the structure of a self-generating luminous tire according to an embodiment of the present invention.

[0030] refer to Figure 1 As shown, the self-generating luminous tire includes a first power generating element, which is disposed on the inner wall of the tire tread 4 along the center line of the tire tread 4.

[0031] To ensure the first power generation component is securely installed on the inner wall of the tire, such as... Figure 2As shown, the first film layer 101 is connected to the inner wall of the tire tread 4 via a rubber layer 102. A groove for fixing the first film layer 101 is provided along the centerline of the tire tread 4 on the inner wall of the tire tread 4. The rubber layer 102 is fixed within the groove by an adhesive layer 103. The groove helps prevent the first power generation component from sliding or falling off.

[0032] Continue to refer to Figure 1 The self-generating light-emitting tire includes a second power-generating element, which is connected to the tire rim 5 via an elastic element and is disposed opposite to the first power-generating element.

[0033] The second generator is connected to the tire rim 5 using an elastic element. This serves two purposes: firstly, it secures the second generator to the tire; secondly, during high-speed driving, the centrifugal force always extends outward along the normal direction. Due to this centrifugal force, the second generator moves outward, while the elastic element deforms, generating a pull-back force. The two gradually reach a force balance. However, when the second generator reaches its lowest point, it is perpendicular to the ground and pointing downward. At this point, the addition of gravity disrupts the original force balance, causing the second generator to continue moving downward and come into contact with the first generator on the tire. As the tire continues to rotate, the direction of gravity changes, causing the second generator to move inward again. This leads to the separation of the first and second generators, generating electricity using the principle of contact-separation generation between the first and second generators.

[0034] The self-generating luminous tire includes a luminous element. The luminous element is connected to a first luminous element and a second luminous element via a circuit; when the tire rotates, an elastic element causes the second luminous element to be in contact with the first luminous element at a first position, and the elastic element causes the second luminous element to be in a second position away from the first luminous element; when the second luminous element is in the first position, the circuit is connected and the luminous element emits light.

[0035] The aforementioned self-generating luminous tire generates electricity by setting a first power-generating element and a second power-generating element, and defining their positions within the tire to ensure contact and separation as the tire rolls. A luminous element is further incorporated; as the tire rotates, an elastic element moves the second power-generating element to a first position in contact with the first power-generating element, or moves it to a second position away from the first power-generating element. When the second power-generating element is in the first position, the circuit is connected, and the luminous element emits light. Specifically, based on the principle of contact electrification, the tire generates electricity through the contact and separation of two thin-film materials (the first and second power-generating elements) within the tire due to gravity, centrifugal force, and elasticity during tire movement. During high-speed travel, the centrifugal force always extends outward along the normal direction, while the elastic element, due to stretching, generates a force opposite to the centrifugal force, achieving a force balance. Therefore, gravity becomes the force driving the contact and separation of the first and second power-generating elements. When the second generator rotates to its lowest point as the tire rotates, it contacts the first generator vertically downwards; when it rotates to its highest point as the tire rotates, it separates from the first generator vertically upwards. When the two thin film materials come into contact, one generates electrons and the other receives them, creating a potential difference between them. Since the thin film materials themselves are non-conductive, they can be connected to a light-emitting diode 304 via an external circuit through a rectifier circuit box 303 to emit light. This is safe and environmentally friendly, improving nighttime driving safety, enhancing vehicle visibility, and satisfying the public's pursuit of personalization.

[0036] In some embodiments, the first power generation device includes a first thin film layer 101, which is made of polydimethylsiloxane; the second power generation device includes a second thin film layer 201, which is made of polyester fiber.

[0037] The principle of contact-separation power generation utilizes the binding force of charges between different thin film materials. By contacting and separating, the charge distribution on the surface of the dielectric material is changed. The dielectric material with weaker binding force loses electrons, while the dielectric material with stronger charge binding force gains electrons. Through contact and friction, electrons are transferred from one material to another. When the two thin film materials separate, the transfer of electrons breaks the original potential balance and generates a potential difference.

[0038] like Figure 3 As shown, the elastic element is a spring 202. To ensure that the second and first power generating elements can accurately contact and separate as the tire rotates, a sleeve 203 is provided around the spring 202 to guide its extension and retraction. The sleeve 203 is arranged along the radial line of the tire rim 5 and connected to the tire rim 5. The sleeve 203 can fix the movement direction of the spring 202 and the hollow rubber rod 204, preventing them from swinging under high-speed tire movement, thus playing a protective role.

[0039] To reduce friction between the sleeve 203 and the hollow rubber rod 204, a ball bearing 205 is provided between the sleeve 203 and the hollow rubber rod 204 to increase the stroke of the rubber rod 204 and prevent the hollow rubber rod 204 from having too little stroke due to excessive friction, which would prevent the two film materials from contacting and separating.

[0040] like Figure 4 As shown, a fixing hole 206 is provided on the tire rim 5. The sleeve 203 is connected to the fixing hole 206 through a fixing bracket 207 to be perpendicular to the tire rim 5 and fixedly connected to it. The fixing hole 206 has two functions: First, when the sleeve 203 is working, the fixing hole 206 connected to the fixing bracket 207 firmly fixes the sleeve 203 in a direction perpendicular to the rim 5, preventing it from swinging with the rotation of the tire. Fixing it through the fixing hole 206 completely secures it to the rim 5, facilitating tire installation. Second, the fixing hole 206 connecting the sleeve 203 to the fixing hole 206 of the rim 5 ensures that the sleeve 203 is always perpendicular to the rim 5, preventing the sleeve 203 from swinging back and forth, which would affect power generation efficiency and driving safety.

[0041] In some embodiments, the circuit includes a first electrode 301, a rectifier circuit box 303, and a second electrode 302. The first electrode 301 is located on the side of the first thin film layer 101 facing away from the second thin film layer 201, and the second electrode 302 is located on the side of the second thin film layer 201 facing away from the first thin film layer 101. The first electrode 301, the rectifier circuit box 303, and the second electrode 302 are connected by wires. The first electrode 301 is located between the rubber layer 102 and the first thin film layer 101 and is connected to a circuit latch 305 by a wire. The second electrode 302 is installed at the bottom of the second thin film layer 201 and is connected to a power latch via a wire passing through the interior of a hollow rubber rod 204. The circuit latch 305 is connected to the rectifier circuit box 303 by a wire, forming an input circuit with the first electrode 301 and the second electrode 302.

[0042] In some embodiments, the light-emitting element is a light-emitting diode (LED) 304 mounted on the outer side of the tire rim 5. The LED 304 is connected to a rectifier circuit box 303 via wires. The rectifier circuit box 303 is connected to the LED 304 via wires, serving as the output circuit. The LED 304, mounted on the outer side of the rim 5, generates electricity using the current produced by the tire's high-speed movement, which is used for personalized design. Simultaneously, under suitable road conditions, the tire area naturally emits light, which is both aesthetically pleasing and safe. The LED 304 mounted on the outer side of the rim 5 can be selected in different colors according to the consumer's preferences, achieving personalized customization.

[0043] The circuit of this invention is divided into an input circuit, a rectifier circuit box 303, and an output circuit. The input circuit consists of a first electrode 301 and a second electrode 302 connected to the rectifier circuit box 303 via wires and circuit clips 305. The output circuit consists of a diode connected to the rectifier circuit box 303 via wires. All three circuits can be replaced individually without affecting each other, and when combined, they form a complete light-emitting circuit. Through this structural design, the kinetic energy of the tires can be used to generate electricity without consuming additional energy.

[0044] The power generation principle of the aforementioned self-generating luminous tire is contact-separation power generation. Specifically, during high-speed driving, the tire generates a centrifugal force that always extends outwards along the normal direction. Due to this centrifugal force, the hollow rubber rod 204 moves outwards, while the spring 202 deforms, generating a pull-back force. The two forces gradually reach equilibrium. However, when the sleeve 203 rotates downwards to be perpendicular to the ground, the addition of gravity disrupts the original force balance, causing the hollow rubber rod 204 to continue moving downwards and come into contact with the first thin film layer 101. As the tire continues to rotate, the direction of gravity changes, causing the hollow rubber rod 204 to move inwards again, thus separating the two materials. The generated current passes through the input circuit, rectifier circuit, and output circuit, connecting to a diode. The light-emitting diode 304 is positioned on the outside of the rim 5, thus emitting light.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
