Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic product technology, and in particular to a battery fixing structure for CD players. Background Technology
[0002] CD players are popular among many users due to their portability and good acoustics. A typical CD player includes a housing, playback module, PCB board, battery, speaker, and speaker cover. The housing usually consists of a top and bottom shell. Traditional CD players typically use battery clips to secure the battery, which are then fixed to the housing with screws to prevent loosening and falling out. This not only results in a complex structure with many parts, but also increases costs due to the need for a separate mold for the battery clips. Furthermore, the use of screws for fixing the battery makes assembly inconvenient and inefficient. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a battery fixing structure for CD players that is simpler in structure, more rational in design, has fewer parts, lower in cost, and is easier and faster to assemble.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a battery fixing structure for a CD player, including a housing, a PCB board, a battery, a playback component, and a speaker. The housing includes a top shell and a bottom shell, which are assembled and fixed together. A speaker cover is provided inside the housing for mounting and fixing the speaker, and the speaker cover forms an acoustic cavity. A battery receiving and supporting structure is provided on the bottom shell. A protruding pressure arm is provided on the speaker cover near the receiving and supporting structure. A pressure rib is provided in the top shell extending toward the bottom shell. The battery is placed in the receiving and supporting structure of the bottom shell, and the pressure arm and pressure rib press down on the upper two sides of the battery to fix the battery in the receiving and supporting structure of the bottom shell.
[0005] Furthermore, the two sides of the speaker cover protrude towards the top shell, forming a recessed groove in the middle, in which the PCB board is embedded and covers the battery.
[0006] Furthermore, the housing support structure on the bottom shell is located in the rear region of the bottom shell, the pressure arm extends backward from the rear of the groove of the horn cover, and the pressure rib is located in the rear region of the top shell; the battery is placed horizontally in the housing support structure, and the pressure arm and pressure rib press down on the front and rear sides of the battery respectively.
[0007] Furthermore, the surface of the battery is an arc-shaped structure, and the bottom surface of the pressure arm is provided with an arc-shaped pressing part that matches the surface of the battery. The bottom edge of the pressure bone is also an arc-shaped concave structure. The arc-shaped pressing part of the pressure arm and the arc-shaped concave part of the pressure bone press the front top surface and side surface and the rear top surface and side surface of the battery, respectively.
[0008] Furthermore, the housing support structure includes a support base with an arc-shaped support portion that matches the battery surface, and an arc-shaped inner wall on the inner side of the tail end of the bottom shell, which supports the battery by cooperating with the arc-shaped support portion.
[0009] Furthermore, the support base, pressure arm, and pressure bone are all provided in two locations, one on the left and one on the right, respectively, close to the left and right ends of the battery.
[0010] Furthermore, each pressure arm has two arc-shaped pressing parts, and there is a hollow groove between the two arc-shaped pressing parts. The entire pressure arm and the horn cover are an integral structure.
[0011] Preferably, the support base and the bottom shell are an integral structure, and the pressure plate and the top shell are an integral structure.
[0012] This invention features a pressure arm on the horn cover, a pressure rib on the top shell, and a receiving and supporting structure on the bottom shell. The battery is placed within the receiving and supporting structure. After the horn cover and top shell are installed, the pressure arm and pressure rib work together to press the battery down from both sides. This replaces the original independent battery clamp, thereby reducing the number of parts, lowering costs, and eliminating the need for screws to install and fix the battery, making assembly more convenient and faster.

Detailed Implementation
[0020] In this embodiment, refer to Figures 1-6The battery fixing structure of the CD player includes a housing, a PCB board 4, a battery 5, a playback component 6, and a speaker 7. The housing includes a top shell 1 and a bottom shell 2, which are assembled and fixed together. The playback component 6 is mounted on the top shell 1. A speaker cover 3 is provided inside the housing for mounting and fixing the speaker 7, and the speaker cover 3 forms an acoustic cavity. A housing support structure for the battery 5 is provided on the bottom shell 2. A protruding pressure arm 32 is provided on the speaker cover 3 near the housing support structure. A pressure rib 11 protruding toward the bottom shell 2 is provided in the top shell 1. The battery 5 is placed in the housing support structure of the bottom shell 2. The pressure arm 32 and the pressure rib 11 press down on the upper sides of the battery 5 to fix the battery 5 in the housing support structure of the bottom shell 2. This eliminates the need to use screws and battery clamps to fix the battery 5.
[0021] The speaker cover 3 has two sides that bulge towards the top shell, forming a recessed groove 31 in the middle. The PCB board 4 is embedded in the groove 31 and covers the battery 5, which can separate the battery 5 from the playback component 6 to prevent the heat from accumulating and affecting the battery.
[0022] The accommodating support structure on the bottom shell 2 is located in the rear region of the bottom shell 2. The pressure arm 32 extends backward from the rear of the groove 31 of the horn cover 3. The pressure bone 11 is located in the rear region of the top shell 1. The battery 5 is placed horizontally in the accommodating support structure. The pressure arm 32 and the pressure bone 11 press down on the front and rear sides of the battery 5 respectively.
[0023] The surface of the battery 5 is arc-shaped. The bottom surface of the pressure arm 32 is provided with an arc-shaped pressing part 33 that matches the surface of the battery 5. The bottom edge of the pressure bone 11 is also an arc-shaped concave structure. The arc-shaped pressing part 33 of the pressure arm 32 and the arc-shaped concave part of the pressure bone 11 press the front top surface and side surface and the rear top surface and side surface of the battery 5 respectively, so as to achieve a wrapping effect from top to side, thereby improving the stability of fixing the battery 5.
[0024] The housing support structure includes a support base 21, which has an arc-shaped support portion 22 that matches the surface of the battery 5. The inner side of the tail end of the bottom shell 2 has an arc-shaped inner wall 23. The battery 5 is supported by the arc-shaped inner wall 23 in conjunction with the arc-shaped support portion 22. This can make full use of the shape matching to improve the installation stability of the battery 5.
[0025] The support base 21, pressure arm 32 and pressure bone 11 are all provided in two locations on the left and right sides, respectively, close to the left and right ends of the battery 5, to fix the battery 5 from the left and right sides and improve stability.
[0026] Each pressure arm 32 has two arc-shaped clamping parts 33, which improves the stability of clamping. There is a hollow groove 34 between the two arc-shaped clamping parts 33, which can save materials. The entire pressure arm 32 and the horn cover 3 are integrated into one structure and are injection molded.
[0027] The support base 21 and the bottom shell 2 are an integral structure, and the pressure rib 11 and the top shell 1 are an integral structure, both of which are injection molded as a single unit.
[0028] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
