Description

Technical Field

[0001] This utility model relates to the field of mobile phone case technology, and in particular to an integrated mobile phone case that provides eye protection light for the mobile phone screen. Background Technology

[0002] Phone cases are decorative items used to protect or enhance the appearance of mobile phones. With the rapid development of technology, the "tech beauty" industry has emerged as a new sector. Fashionable IT brands, along with the diversification of the market, have diversified their product offerings to cater to the increasing variety of mobile phone brands and functions. Phone cases are categorized by material, including PC cases, leather, silicone, fabric, hard plastic, leather cases, tempered glass metal cases, soft plastic, velvet, and silk, among others. Phone cases not only enhance your phone's appearance but also protect it from drops, scratches, water, and shocks.

[0003] Patent application number CN202021657000.6 is a Chinese utility model patent, disclosing a shock-absorbing and drop-proof phone case, including a phone case with an upper half and a lower half of the phone case attached together. An anti-collision pad with a wave-shaped structure is embedded between the upper half and the lower half of the phone case. An anti-collision plate is snapped between the upper and lower half of the phone case. Spring grooves are formed on both sides of the upper half of the phone case along the opening direction, and springs are embedded in the two spring grooves. In this utility model, the shock-absorbing and drop-proof phone case, through the design of the anti-collision plate and springs, effectively prevents the upper half of the phone case from falling and protects it from damage. The upper and lower halves of the phone case shift, providing elastic support from the springs in the spring grooves. This elastic support, along with the limiting blocks on the anti-collision plate, absorbs shock when the phone is dropped, improving the case's shock absorption and drop protection. Upon impact with the upper and lower halves, the internal anti-collision pads deform, protecting the inner phone case and further absorbing shock during drops. However, this phone case has the following problems: First, it does not provide eye protection and cannot effectively alleviate visual fatigue; second, it does not improve user comfort. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies. This phone case forms a uniform and soft eye-protecting light source at the edge of the screen by setting LED patch beads and optical fibers. By using thermoplastic polyurethane rubber as the overall material, the induction coil, LED beads and other components are completely embedded in the bottom surface of the case and the surface is flush. In addition, the arc-shaped folded edge improves the portability and comfort of the phone case. This solves the technical problems of existing phone cases that cannot provide active eye protection function, cannot relieve visual fatigue and cannot improve the comfort of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated phone case providing eye-protecting light for the phone screen includes a phone case body. The bottom interior of the phone case body has three grooves extending to the edge of the bottom interior. The upper side of the phone case body has an upwardly and inwardly extending arc-shaped fold. An induction coil is located at the center of the bottom interior of the phone case body. The induction coil is electrically connected to three LED surface-mount lamp beads, which are respectively positioned to the left, right, and bottom of the induction coil. Each of the three LED surface-mount lamp beads has a light-emitting surface on its outer side, facing the corresponding groove. The center of each light-emitting surface is optically coupled to an optical fiber, and the number of optical fibers corresponds to the number of grooves.

[0007] As a preferred embodiment, the three grooves extend from the bottom of the inside of the phone case body to the inner edge of the arc-shaped fold, forming a through-type light guide channel.

[0008] As a preferred embodiment, the lower end of each optical fiber is fixedly connected to the bottom center position of the corresponding groove.

[0009] As a preferred embodiment, the light-incident end of the optical fiber is aligned with the center of the light-emitting surface of the LED chip lamp bead, and the light-emitting end of the optical fiber extends to the inner edge of the arc-shaped fold through a corresponding groove.

[0010] As a preferred embodiment, the LED chip lamp beads and the induction coil are embedded inside the bottom of the phone case body, and the upper surface of the induction coil and the upper surface of the LED chip lamp beads are flush with the bottom surface of the phone case body.

[0011] As another preferred option, the entire body of the phone case is made of thermoplastic polyurethane rubber.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, the LED chip lamp bead can be activated by the induction coil to emit light by putting on the mobile phone case. Then, the light of the LED chip lamp bead is extended to the edge of the mobile phone screen through the through light guide channel formed by the groove and the inner edge of the arc folded edge by the optical fiber that is optically coupled with the light-emitting surface. This allows the light to diffuse around the edge of the mobile phone screen, forming a uniform and soft eye-protecting light source, creating a low-intensity, flicker-free background light environment, neutralizing the blue light emitted by the mobile phone screen, and reducing visual discomfort when using the mobile phone for a long time.

[0014] (2) In this utility model, the induction coil, LED chip lamp beads and optical fiber are all built into the bottom of the phone case body, and the upper surface of the induction coil and the upper surface of the LED lamp beads are flush with the bottom of the phone case, avoiding extra protrusions and improving the overall grip of the phone case. Users can simply put it on like a regular phone case, which greatly improves convenience and portability.

[0015] (3) In this utility model, thermoplastic polyurethane rubber is used as the overall material to ensure that the light guide channel formed by the groove and the arc edge is not easily deformed and to maintain the stability of light transmission. At the same time, thermoplastic polyurethane rubber has excellent comprehensive properties such as high strength, high toughness, wear resistance and oil resistance, which can effectively increase the service life of the mobile phone case.

[0016] In summary, this device offers advantages such as providing eye protection, effectively relieving visual fatigue, excellent convenience and portability, and effectively increasing the lifespan of phone cases, making it particularly suitable for the field of phone case technology.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figures 1 to 3As shown, this utility model provides an integrated phone case that provides eye-protecting light for mobile phone screens. It includes a phone case body 1, the interior of which is a phone-accommodating cavity for easy phone use. The bottom of the phone case body 1 has three grooves 11 extending to the inner edge of the bottom. Each groove 11 has a depth of 0.5mm and a width slightly larger than the diameter of the optical fiber 4. The upper side of the phone case body 1 has an upwardly and inwardly extending arc-shaped folded edge 12, which bends inward and its inner edge fits against the edge of the phone screen, ensuring uniform light coverage of the screen edge. An induction coil 2 is located at the center of the bottom of the phone case body 1. The induction coil 2 is electrically connected to a PCB board, which is integrated with the induction coil 2. The PCB board is thin and lightweight and includes modules such as a rectifier circuit and a current-limiting resistor. When the phone is placed on the device, the induction coil 2 is positioned precisely at the location of the wireless charging module inside the phone. It can receive the alternating magnetic field generated by the wireless charging module and convert it into a microcurrent. This microcurrent is rectified by the PCB board and converted into direct current to drive the three LED chips 3 to emit light. It is ready to use immediately without the need for an external power source, improving overall convenience. The induction coil 2 is electrically connected to the three LED chips 3, which are respectively positioned on the left, right, and bottom sides of the induction coil 2. Each of the three LED chips 3 has a light-emitting surface 31 on its outer side, which faces the corresponding groove 11. The center of each light-emitting surface 31 is optically coupled to an optical fiber 4. The coupling point between the light-emitting surface 31 and the optical fiber 4 is coated with UV-curable adhesive, which can effectively fix the connection between the light-emitting surface 31 and the optical fiber 4. The number of optical fibers 4 corresponds to the number of grooves 11.

[0024] Furthermore, the three grooves 11 extend from the bottom inside the phone case body 1 to the inner edge of the arc-shaped folded edge 12, forming a through-type light guide channel.

[0025] Furthermore, the lower end of each optical fiber 4 is fixedly connected to the bottom center position of the corresponding groove 11.

[0026] Furthermore, the light-inlet end of the optical fiber 4 is aligned with the center of the light-emitting surface 31 of the LED chip lamp bead 3, and the light-emitting end of the optical fiber 4 extends to the inner edge of the arc-shaped fold 12 through the corresponding groove 11. After the light enters the optical fiber 4 from the light-inlet end, it is transmitted along the through-type light guide channel formed by the groove 11 and the arc-shaped fold 12. The inward extension of the arc-shaped fold 12 guides the light to the edge of the screen, transforming the point light source into a surface light source, which diffuses around the mobile phone screen and outputs a uniform and soft background light.

[0027] Furthermore, the LED chip lamp 3 and the induction coil 2 are embedded in the bottom of the inside of the phone case body 1, and the upper surface of the induction coil 2 and the upper surface of the LED chip lamp 3 are flush with the bottom of the inside of the phone case body 1. The induction coil 2 and the LED chip lamp 3 are embedded in thermoplastic polyurethane rubber material through injection molding process, and their flush surfaces eliminate any protrusions, ensuring that the back of the phone is flat when installed. Users can simply put it on like a regular phone case, which greatly improves convenience and portability.

[0028] Furthermore, the entire body 1 of the phone case is made of thermoplastic polyurethane rubber, also known as TPU, which has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. This ensures that the light guide channel formed by the groove 11 and the arc-shaped folded edge 12 is not easily deformed, maintains the stability of light transmission, and can effectively increase the service life of the phone case.

[0029] Working process: First, when the user puts the phone into the phone case body 1, the alternating magnetic field generated by the wireless charging coil built into the phone penetrates the material of the case and activates the induction coil 2. Through the principle of electromagnetic induction, a microcurrent is generated to drive the LED chip beads 3 on the left, right and bottom sides to emit light. The light from the LED chip beads 3 is optically coupled to the light-emitting surface 31 by the optical fiber 4, and extends to the edge of the phone screen through the through light guide channel formed by the groove 11 and the inner edge of the arc-shaped fold 12. This allows the light to diffuse around the edge of the phone screen and diffuse along the edge of the screen to form a flicker-free eye-protecting light environment.
