Description

Technical Field

[0001] This application relates to the field of cup technology, and in particular to an LED dot matrix screen adapted to the structure of a cup. Background Technology

[0002] LED dot matrix displays are widely used in various products due to their high brightness, long lifespan, and low energy consumption. Existing cup bodies are typically double-layered conical structures, narrower at the top and wider at the bottom. When LED dot matrix displays are applied to cup bodies, the inconsistency in their shapes prevents the LED beads from adhering tightly to the outer shell. This creates gaps between the LED dot matrix display and the outer shell. Consequently, in areas where the LED dot matrix display is tightly fitted, the light emitted appears brighter on the outer shell; while in areas where it is not tightly fitted, the light appears darker due to scattering or refraction, severely impacting the product's visual appeal. Summary of the Invention

[0003] In view of this, this application proposes an LED dot matrix screen adapted to the structure of a cup, suitable for installation between the inner liner and the outer shell of the cup, including: a circuit board, an array of LED beads and control components;

[0004] The LED bead assembly arranged in an array is fixedly attached to the circuit board, and the control components are set on the edge of the circuit board and attached to the outer shell of the cup, which is suitable for controlling the LED bead assembly;

[0005] The circuit board has a curved sheet structure, and the curved surface of the circuit board matches the curved surface of the cup shell. This is suitable for when the circuit board is installed between the inner liner and the outer shell of the cup, so that the LED assembly fits tightly with the outer shell of the cup.

[0006] In one possible implementation, the main body of the circuit board has a fan-shaped structure that is narrower at the top and wider at the bottom.

[0007] In one possible implementation, the central angle of the circuit board is equal to the angle between the conical generatrix of the cup body, and the value of the central angle of the circuit board ranges from 5° to 15°.

[0008] In one possible implementation, a clamping assembly is also included; the clamping assembly is fixedly installed between the inner liner and the outer shell, and is located on the side of the circuit board away from the LED beads.

[0009] In one possible implementation, the compression component is compression foam; the compression foam is filled between the circuit board and the inner liner.

[0010] In one possible implementation, the clamping assembly also includes a heat-dissipating copper sheet; the heat-dissipating copper sheet is disposed between the clamping foam and the circuit board, and the heat-dissipating copper sheet is in close contact with the circuit board.

[0011] In one possible implementation, the circuit board is an FPC flexible board.

[0012] In one possible implementation, the control element is a touch sensor.

[0013] Beneficial effects of this application

[0014] Due to the incompatibility with the conical cup body, the LED dot matrix lamp beads cannot fit tightly against the outer wall of the cup during installation, resulting in uneven light propagation from the lamp beads. Compared with existing technologies, this application designs the dot matrix screen in a curved shape, and the curved shape of the circuit board matches the curved surface of a conical cup that is narrower at the top and wider at the bottom. When installed between the inner liner and the outer shell of the cup, the LED components on the circuit board can be closely arranged along the conical surface and evenly distributed on the surface of the cup. The close fit between the LED components and the conical surface of the cup ensures that the light emitted by the LED components is subject to the same scattering and refraction when passing through the outer shell of the cup, thereby ensuring the brightness and color uniformity of the entire display area and avoiding uneven brightness in some areas. This ensures the integrity and clarity of the displayed content. When people observe the display screen on the cup, their line of sight can be approximately considered to be parallel to the axis of the cone. Because the curved dot matrix screen is distributed along the conical surface, based on the projection principle, the curved LED dot matrix screen utilizes the inclination of the cup, so that the originally curved image projection on the LED dot matrix screen gradually approaches a rectangle in the eyes of the viewer. This avoids the distortion of the display image due to the curved surface of the cup, ensuring a clearer and more complete display effect and improving the user experience.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0027] This application proposes an LED dot matrix screen adapted to the structure of a cup, suitable for installation between the inner liner 310 and the outer shell 320 of the cup, such as... Figures 1 to 4As shown, the device includes a circuit board 110, an array of LED beads, and a control component 130. The array of LED beads is fixedly attached to the circuit board 110. The control component 130 is disposed on the edge of the circuit board 110 and fits against the outer shell 320 of the cup body, and is suitable for controlling the LED beads. The circuit board 110 has a curved sheet structure, and the curved surface of the circuit board 110 matches the curved surface of the outer shell 320 of the cup body, so that when the circuit board 110 is installed between the inner liner 310 and the outer shell 320 of the cup body, the LED beads fit tightly against the outer shell 320 of the cup body.

[0028] It should be noted that circuit board 110 provides a mounting base for the LED chip assembly, ensuring that the assembly does not shake or shift during use. The input terminal of the LED chip assembly is electrically connected to the output terminal of circuit board 110, which provides power to the assembly. The LED chip assembly displays various images or numbers by switching on and off. The array arrangement of the LED chips allows for the creation of complex patterns and text, ensuring uniform brightness distribution across the entire display. This avoids localized over-brightness or under-brightness due to uneven distribution or excessive brightness differences among the LED chips. The output terminal of control component 130 is electrically connected to the input terminal of circuit board 110, and control component 130 controls the LEDs based on the received signals. The operating status of the LED components is controlled by the control element 130, which controls the LED components at different positions to turn on or off or display different colors, thereby realizing dynamic changes in the displayed content. The curved circuit board 110 is adapted to the curved surface of the cup body, so that the LED components on the circuit board 110 can be tightly attached to the cup body shell 320. The tight-fitting design allows the light emitted by the LED components to pass through the cup body shell 320 more effectively, reducing the loss caused by light scattering and refraction, making the displayed image or text brighter and clearer. It avoids the situation where some areas are too bright or too dark due to inconsistent light propagation caused by gaps between the LED components and the cup body, ensuring the uniformity and integrity of the image displayed on the surface of the cup body.

[0029] Traditional planar LED dot matrix screens suffer from uneven light propagation because their shape doesn't match the conical cup shape. During installation, the LED dot matrix components cannot fit snugly against the outer wall of the cup. In contrast, this application designs the dot matrix screen in a curved shape, with the circuit board 110's curved shape matching the curved surface of the conical cup (narrower at the top and wider at the bottom). When installed between the inner liner 310 and the outer shell 320 of the cup, the LED components on the circuit board 110 are tightly arranged along the conical surface and evenly distributed across the cup's surface. This close fit between the LED components and the cup's conical surface ensures that the light emitted by the LED components experiences uniform scattering and refraction as it passes through the outer shell 320, thus guaranteeing uniform brightness and color across the entire display area. This design avoids uneven brightness in the display area, ensuring the integrity and clarity of the displayed content. When people observe the display screen on the cup, their line of sight can be approximated as parallel to the axis of the cone. Because the curved dot matrix screen is distributed along the curved surface of the cone, based on the principle of projection, the curved LED dot matrix screen utilizes the slope of the cup, making the originally curved image projection on the LED dot matrix screen gradually approach a rectangle in the eyes of the viewer. This avoids the display image being distorted due to the curved surface of the cup, ensuring a clearer and more complete display effect and improving the user experience.

[0030] In one possible implementation, the main body of the circuit board 110 has a fan-shaped structure that is narrower at the top and wider at the bottom. It should be noted that "narrower at the top and wider at the bottom" specifically refers to the fact that the side of the circuit board 110 near the rim of the cup is narrower, while the side near the bottom is wider. This fan-shaped design of the circuit board 110 matches the conical surface of the cup body. This allows the LED beads on the circuit board 110 to fit more closely and naturally against the conical surface of the cup body when the LED dot matrix screen is installed between the inner liner 310 and the outer shell 320. This effectively avoids incomplete displays or uneven brightness caused by a mismatch between the shape of the circuit board 110 and the outer shell 320, further optimizing the display effect and ensuring the uniformity and integrity of the display area.

[0031] In one possible implementation, such as Figure 4As shown, the LED assembly includes two or more LEDs 120, which are arranged in an array on a fan-shaped circuit board 110. The distance between any two adjacent rows of LEDs 120 is the same; that is, each row of LEDs 120 is evenly arranged along the width of the circuit board 110, and the distance between any two adjacent LEDs 120 within each row is the same. The distance between adjacent columns of LEDs 120 gradually decreases along the width of the circuit board 110; that is, the distance between any two adjacent LEDs 120 in the upper row is greater than the distance between any two adjacent LEDs 120 in the lower row, or vice versa. This arrangement is suitable for use with a fan-shaped circuit board 110.

[0032] Furthermore, the LED 120 adopts the existing tri-color LED 120.

[0033] In one possible implementation, each LED bead 120 is attached to the circuit board 110 via SMT surface mount technology.

[0034] In one possible implementation, the central angle of the circuit board 110 is equal to the angle between the conical generatrix of the cup body. It should be noted that the angle between the conical generatrix of the cup body specifically refers to the angle formed between any two generatrixes extending from the apex of the conical cup body along its side surface to the bottom edge of the cup body. The design that the central angle of the circuit board 110 is equal to the angle between the conical generatrix of the cup body allows the edge of the circuit board 110 to coincide with the generatrix of the conical cup body. This ensures that the LED beads 120 on the circuit board 110 are evenly and tightly fitted to the outer shell 320 of the cup body, and that the distance between the LED beads 120 and the outer shell 320 remains consistent. The light emitted by the LED beads 120 can pass through the outer shell 320 of the cup body along the same path and at the same angle, ensuring uniform brightness and color consistency in the display area, and improving the quality and visual effect of the displayed image.

[0035] Furthermore, the central angle of circuit board 110 ranges from 5° to 15°.

[0036] In one possible implementation, circuit board 110 adopts the FPC flexible board as used in the prior art.

[0037] In one possible implementation, the control element 130 uses a touch sensor from the prior art. It should be noted that the touch sensor allows users to control the dot matrix screen to turn the lights on or off, adjust the brightness, and switch display modes through simple touch operations. This interaction method is intuitive and convenient, without the need for complicated operation procedures, thus improving the user experience. The touch sensor does not require additional mechanical buttons, making the surface of the cup simpler and flatter, and enhancing the aesthetics of the cup.

[0038] In one possible implementation, such as Figure 3 As shown, it also includes a clamping assembly 210; the clamping assembly 210 is fixedly installed between the inner liner 310 and the outer shell 320 of the cup body, and is located on the side of the circuit board 110 opposite to the LED bead 120. It should be noted that the clamping assembly 210 firmly fixes the circuit board 110 between the inner and outer shells 320 of the cup body, preventing the circuit board 110 from shaking or shifting inside the cup body. At the same time, by applying a certain pressure to the circuit board 110 through the clamping assembly 210, the LED bead 120 on the circuit board 110 is better fitted to the curved surface of the outer shell 320 of the cup body, further improving the adhesion between the LED bead 120 and the surface of the cup body.

[0039] In one possible implementation, the clamping component 210 is clamping foam; the clamping foam fills the space between the circuit board 110 and the inner liner 310 of the cup. It should be noted that the foam can adaptively adjust according to the shape of the circuit board 110 and the cup body, thereby better filling the gap between the circuit board 110 and the inner liner 310 of the cup, ensuring a tight fit between the LED beads 120 on the circuit board 110 and the outer shell 320 of the cup body, thus guaranteeing the uniformity of brightness and the integrity of the display area.

[0040] In one possible implementation, such as Figure 2 , Figure 3 As shown, the clamping assembly 210 also includes a heat dissipation copper sheet 220; the heat dissipation copper sheet 220 is disposed between the clamping foam and the circuit board 110, and the heat dissipation copper sheet 220 is in close contact with the circuit board 110.

[0041] It should be noted that copper has good thermal conductivity. The heat sink copper sheet 220 is in close contact with the circuit board 110, which can quickly conduct away the heat generated by the circuit board 110 and the LED beads 120 during operation, preventing heat from accumulating on the circuit board 110. This reduces the temperature of the circuit board 110 and the LED beads 120, preventing the circuit board 110 or the LED beads 120 from degrading in performance, shortening their lifespan, or even being damaged due to overheating. At the same time, the heat sink copper sheet 220 has a certain rigidity, which can provide some support between the circuit board 110 and the compression foam. The heat sink copper sheet 220 evenly transfers the pressure generated by the compression foam to the circuit board 110, preventing damage to the circuit board 110 or the LED beads 120 due to excessive local pressure.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
