Description

Technical fields:

[0001] This utility model relates to the field of charging case technology, and specifically to an earphone charging case for storing and charging Bluetooth earphones. Background technology:

[0002] The charging case for the earbuds has a cavity formed inside the earbuds, and two flexible electrodes are located within this cavity for charging. When the earbuds are placed inside the cavity, their charging electrodes contact the flexible electrodes, initiating charging. To indicate the charging case's status, an indicator light is typically provided, displaying the status through color and flashing. For ease of observation, the indicator light is usually located on the front side of the charging case.

[0003] Currently, there is a semi-open headphone charging case. To achieve a wider opening angle, the joint surface between the lid and the case body is a curved or sloping surface with increasing height from front to back. When the charging case is opened, the headphone housing inside is almost completely exposed, making it convenient for users to take out and put in the headphones. However, this semi-open structure makes it inconvenient to install indicator lights. This is because: since the joint surface is a curved or sloping surface with increasing height, the front area of ​​the charging case is relatively small. Opening a light-transmitting hole on the front of the charging case would place it close to the bottom of the headphone case, limiting the installation space for the indicator light. Additionally, the placement of the circuit board inside the charging case must be considered, all of which make directly installing an indicator light very inconvenient. The current approach is to use a light guide to change the light transmission path, guiding the light emitted by the indicator light to the light-transmitting hole on the front of the charging case. However, current products suffer from unstable assembly of the light guide and inconvenient circuit board installation. Utility Model Content:

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a charging case for earphones with a semi-open structure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The earphone charging case includes a cover and a box body pivotally connected to each other by a pivot. The box body includes an outer shell and an inner shell, and a cavity for placing earphones is formed on the upper surface of the inner shell. A cavity is formed between the outer shell and the inner shell, and a circuit board and a battery are installed in the cavity. A lamp hole is provided on the front surface of the outer shell. The circuit board is vertically installed in the cavity, and a light-emitting lamp is provided on the front surface of the circuit board. A light guide is provided between the light-emitting lamp and the lamp hole. The light guide includes a light guide body with a tortuous shape. The light-incident surface of the light guide body is close to the light-emitting lamp, and the light-emitting surface of the light guide body extends integrally to form a light guide column inserted into the lamp hole. The light generated by the light-emitting lamp is conducted to the light guide column after passing through the light guide body.

[0006] Furthermore, in the above technical solution, the inner wall of the outer shell is provided with a mounting part for mounting the light guide, and the mounting part limits the light guide in the lateral direction.

[0007] Furthermore, in the above technical solution, the mounting part includes: two clamping plates that clamp the light guide body and a support plate disposed between the two clamping plates, and a slot is provided on the clamping plate; the light guide body clamped by the two clamping plates is located on the support plate, and a transverse locking block is provided on the left and right sides of the light guide body, and the transverse locking block is engaged with the slot.

[0008] Furthermore, in the above technical solution, the inner wall of the inner shell extends downward to form a limiting plate; the upper surface of the light guide body has a longitudinal protrusion that interferes with the limiting plate; and the limiting plate presses against the upper surface of the light guide body.

[0009] Furthermore, in the above technical solution, the light guide body includes: an inclined portion that tilts downward on one side of the self-luminous lamp and a horizontal portion that extends horizontally from the inclined portion; the light generated by the luminous lamp located at a high position is transmitted through the light guide body to the light guide column located at a low position.

[0010] Furthermore, in the above technical solution, the inner wall of the inner shell is provided with a number of mounting posts in the horizontal direction, and the circuit board is fixed to the mounting posts by screws.

[0024] This utility model relates to a charging case for storing and charging earphones. (See attached image) Figures 1 to 6 As shown, this utility model includes a cover 10 and a box 20. The cover 10 and the box 20 are pivotally connected to each other via a pivot 5 to realize the opening or closing of the cover 10.

[0025] The housing 20 adopts a double-layer composite structure, comprising an outer shell 3 and an inner shell 4. That is, after the outer shell 3 and inner shell 4 are processed separately, they are fixedly joined together by means of snap-fit ​​connection, buckle connection, etc. A cavity 40 for placing the earphones is formed on the upper surface of the inner shell 4; a cavity 30 is formed between the outer shell 3 and the inner shell 4, and the circuit board 7 and battery 8 are installed inside the cavity 30.

[0026] This utility model is a semi-open earphone charging case, wherein the mating surface between the cover 10 and the case body 20 is a curved surface (or inclined surface) with increasing height from front to back. Figure 1 As shown, the upper part of the inner shell 4 protrudes upward along the mating surface. When the charging case is opened, the receiving cavity 40 provided on the inner shell 4 is almost completely exposed, making it convenient for users to take out and put in the earphones.

[0027] In this invention, the circuit board 7 is vertically mounted within the cavity 30. Figure 2 As shown, the inner wall of the inner shell 4 is provided with several mounting posts 42 along the horizontal direction. The circuit board 7 is fixed by screws 73 connected to the threaded holes on the mounting posts 42. The vertically arranged circuit board 7 divides the cavity 30 into a front cavity and a rear cavity. An LED light 71 and other electronic components are provided on the side of the circuit board 7 facing the front cavity. The battery 8 is located in the rear cavity and is electrically connected to the circuit board 7. The charging interface 74 is located below the circuit board 7, and an opening 34 corresponding to the charging interface 74 is provided on the bottom surface of the outer shell 3.

[0028] The front surface of the outer casing 3 is provided with a lamp hole 31, and a light guide 6 is provided between the light-emitting lamp 71 and the lamp hole 31. The light generated by the light-emitting lamp 71 is emitted from the lamp hole 31 after passing through the light guide 6.

[0029] The light guide 6 is made of optical plastic material. Light generated by the lamp 71 enters the light guide 6 from the light-incident surface, is conducted along the interior of the light guide 6, and then exits from the light-emitting surface. Specifically, the light guide 6 includes: a light guide body 61 with a zigzag shape, and a light guide post 62, a horizontal locking block 63, and a vertical locking protrusion 64 integrally formed with the light guide body 61. The light guide body 61 includes: an inclined portion 611 that slopes downwards from the lamp 71 side, and a horizontal portion 612 that extends horizontally from the inclined portion 611. The light guide post 62 extends integrally from the front end of the light guide body 61, and corresponds to the lamp hole 31; during installation, the light guide post 62 is inserted precisely into the lamp hole 31.

[0030] With the above-described structure, the light guide 6 can transmit the light generated by the high-positioned light-emitting lamp 71 through the light-incident surface at the front end of the light guide body 61 to the low-positioned light guide column 62. This avoids the problem of insufficient installation space caused by the low position of the lamp hole 31.

[0031] In order to ensure stable installation of the light guide 6, transverse locking blocks 63 are provided on the left and right sides of the light guide body 61, and longitudinal locking protrusions 64 are formed on the upper surface of the light guide body 61.

[0032] The inner wall of the outer casing 3, near the lamp hole 31, is provided with a mounting part for mounting the light guide 6, which limits the light guide 6 in the lateral direction. Specifically, the mounting part includes two clamping plates 32 that hold the light guide body 61 and a support plate 33 disposed between the two clamping plates 32, with slots 321 formed on the clamping plates 32. During installation, the light guide body 61 is located on the support plate 33 and held by the two clamping plates 32, and the lateral locking blocks 63 on the left and right sides of the light guide body 61 engage with the slots 321. At this time, the light guide post 62 at the front end of the light guide 6 is inserted into the lamp hole 31. In this way, the entire light guide 6 is basically limited in the horizontal direction.

[0033] The light guide 6 is vertically positioned using the following structure: the inner wall of the inner shell 4 extends downwards along the vertical direction to form a limiting plate 41. After the light guide 6 is installed on the mounting portion on the inner wall of the outer shell 3, the limiting plate 41 presses against the upper surface of the light guide body 61, and the limiting plate 41 is located behind the longitudinal locking protrusion 64. In this way, the light guide 6 is vertically positioned by the limiting plate 41, and the limiting plate 41 ensures that the light guide 6 will not undergo lateral displacement.

[0034] The circuit board 7 typically has at least two colors of LEDs 71. To prevent light from scattering from the sides, a frame 72 is provided around the LEDs 71, and the end of the light guide body 61 closest to the LEDs 71 is attached to the frame 72. The frame 72 in this invention is made of sponge material, and the elastic compression of the sponge material creates a sealed space between the rear side of the light guide body 61 and the LEDs 71, preventing light leakage.

[0035] During installation, this invention involves first assembling the circuit board 7 and electronic components such as the battery 8 as a whole with the inner shell 4; then, installing the light guide 6 at the mounting portion on the inner wall of the outer shell 3; next, combining the assembled inner shell 4 with the outer shell 3 to form the box body 20; finally, pivotally connecting the box body 20 with the cover 10 via the pivot 5. The entire assembly process is simple, requiring no complex techniques, and the light guide 6 is secured by the outer shell 3 and inner shell 4 within the box body.

[0036] This invention can be used not only in headphones but also in other electronic products. Of course, the above description is merely a specific embodiment of this invention and is not intended to limit its scope. All equivalent changes or modifications made to the structure, features, and principles described in the claims of this invention should be included within the scope of this invention.
