Therefore, it is necessary to improve the waterproofness of in-vehicle screen players and solve the existing technical problems. Utility Model Content

[0004] To overcome the aforementioned technical deficiencies, this utility model provides a waterproof car audio player.

[0005] To solve the above problems, this utility model is implemented according to the following technical solution:

[0006] A waterproof car audio player includes a player housing. One end of the player housing is a closed structure with a PCB board fixedly mounted near its inner end. The other end of the player housing is an open structure with a touch screen. The touch screen is electrically connected to the PCB board. An outer sealing ring is provided between the inner peripheral wall of the open end of the player housing and the touch screen. A side sealing ring is provided between the inner peripheral wall of the player housing and the outer peripheral wall of the touch screen.

[0007] Furthermore, the player housing has an outer snap-fit ​​frame at its open end, and an inner snap-fit ​​frame is fixedly installed inside the housing, opposite to the outer snap-fit ​​frame. A mounting groove is formed between the outer snap-fit ​​frame and the inner snap-fit ​​frame, and the touch screen is fixedly snapped into the mounting groove between the inner snap-fit ​​frame and the outer snap-fit ​​frame.

[0008] Furthermore, the outer sealing ring has an L-shaped cross-section, with its horizontal portion fixedly snapped between the touch display screen and the outer snap-fit ​​frame, and the inner side of the vertical portion of the outer sealing ring flat against the peripheral wall of the outer snap-fit ​​frame.

[0009] Furthermore, the outer snap-fit ​​frame has a plurality of first snap-fit ​​grooves evenly provided along the circumferential direction on its peripheral wall, and the vertical part of the outer sealing ring has a plurality of first snap-fit ​​blocks that are respectively adapted to each of the first snap-fit ​​grooves evenly fixed along the circumferential direction.

[0010] Furthermore, an inner sealing ring is provided between the inner snap-fit ​​frame and the touch display screen. The cross-section of the inner sealing ring is L-shaped. The horizontal part of the inner sealing ring is fixedly snapped between the touch display screen and the inner snap-fit ​​frame, and the inner side of the vertical part of the inner sealing ring is flat against the peripheral wall of the inner snap-fit ​​frame.

[0011] Furthermore, the inner snap-fit ​​frame has a plurality of second snap-fit ​​grooves evenly provided along the circumferential direction on its peripheral wall, and the vertical part of the inner sealing ring has a plurality of second snap-fit ​​blocks that are respectively adapted to each of the second snap-fit ​​grooves evenly fixed along the circumferential direction.

[0012] Furthermore, the cross-sections of the first and second snap-fit ​​slots are both isosceles trapezoidal structures with a wider inner section and a narrower outer section, and the cross-sections of the first and second snap-fit ​​blocks are also isosceles trapezoidal.

[0013] Furthermore, the player housing is fixedly provided with a water-retaining cover perpendicular to the upper part of the touch screen.

[0014] Furthermore, the outer snap-fit ​​frame and the inner snap-fit ​​frame are respectively inclined from the outside to the inside along the direction close to the touch screen, and the side sealing ring has a U-shaped cross section, with its two sides snapped between the outer snap-fit ​​frame and the inner snap-fit ​​frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention effectively ensures the sealing performance of the vehicle-mounted player by sequentially setting an outer sealing ring, a side sealing ring, and an inner sealing ring between the player's outer casing and the touch screen. Furthermore, the two sides of the side sealing ring adopt an inclined mating structure with the outer and inner snap-fit ​​frames respectively, thereby effectively extending the sealing length within a limited space. This prevents moisture from entering the inside of the player's outer casing and corroding the electronic components on the PCB board, thus helping to ensure the service life of the vehicle-mounted player.

[0018] In addition, a sponge ring is provided between the inner peripheral wall of the player housing and the outer peripheral wall of the side sealing ring. This sponge ring has a certain water absorption capacity, thus absorbing moisture that has permeated through the side sealing ring. Furthermore, the sponge ring is compressed between the player housing and the side sealing ring, generating reverse pressure on the side sealing ring. This causes the side sealing ring to tightly abut against the outer and inner snap-fit ​​frames. The inclined structures on opposite sides of the outer and inner snap-fit ​​frames further compress the side sealing ring, ensuring close contact between the two inner sidewalls of the side sealing ring and the upper and lower surfaces of the touchscreen display near its outer edge, thereby further improving the waterproof sealing performance.

[0028] like Figures 1-4 As shown, a waterproof car audio player includes a player housing 1. One end of the player housing 1 is a closed structure, with a PCB board 2 fixedly mounted near its inner end. The other end of the player housing 1 is an open structure and a touch screen 3 is mounted thereon. The touch screen 3 is electrically connected to the PCB board 2. An outer sealing ring 4 is installed between the inner peripheral wall of the open end of the player housing 1 and the touch screen 3, and a side sealing ring 5 is installed between the inner peripheral wall of the player housing 1 and the outer peripheral wall of the touch screen 3.

[0029] In this embodiment, the player housing 1 has an outer card frame 6 at its open end and an inner card frame 7 fixedly disposed inside, opposite to the outer card frame. An installation groove 8 is formed between the outer card frame 6 and the inner card frame 7. The touch screen 3 is fixedly snapped into the installation groove 8 between the inner card frame 6 and the outer card frame 7.

[0030] The outer sealing ring 4 has an L-shaped cross-section. Its horizontal portion is fixedly snapped between the touch display screen 3 and the outer snap-fit ​​frame 6, and the inner side of the vertical portion of the outer sealing ring 4 is flat against the peripheral wall of the outer snap-fit ​​frame 6. A plurality of first snap-fit ​​grooves 9 are evenly provided circumferentially on the peripheral wall of the outer snap-fit ​​frame 6, and a plurality of first snap-fit ​​blocks 10, each adapted to each of the first snap-fit ​​grooves 9, are evenly fixedly provided circumferentially on the vertical portion of the outer sealing ring 4.

[0031] An inner sealing ring 11 is provided between the inner snap-fit ​​frame 7 and the touch screen 3. The cross-section of the inner sealing ring 11 is L-shaped. The horizontal part of the inner sealing ring 11 is fixedly snapped between the touch screen 3 and the inner snap-fit ​​frame 7, and the inner side of the vertical part of the inner sealing ring 11 is flat against the peripheral wall of the inner snap-fit ​​frame 7.

[0032] The inner snap-fit ​​frame 7 has a plurality of second snap-fit ​​grooves 12 evenly provided along the circumferential direction on its peripheral wall, and the vertical part of the inner sealing ring 11 has a plurality of second snap-fit ​​blocks 13 that are respectively adapted to each of the second snap-fit ​​grooves 12 evenly fixed along the circumferential direction.

[0033] In this embodiment, the cross-sections of the first snap-fit ​​groove 9 and the second snap-fit ​​groove 12 are both isosceles trapezoidal structures with a wider inner section and a narrower outer section, and the cross-sections of the first snap-fit ​​block 10 and the second snap-fit ​​block 13 are also isosceles trapezoidal. The first snap-fit ​​block 10 and the second snap-fit ​​block 13 are both made of deformable elastic material, and by respectively cooperating with the corresponding first and second snap-fit ​​grooves, a firm connection can be achieved between the outer sealing ring and the outer snap-fit ​​frame, and between the inner sealing ring and the inner snap-fit ​​frame.

[0034] The outer sealing ring 4, the side sealing ring 5, and the inner sealing ring 11 are all made of silicone.

[0036] This invention effectively ensures the sealing performance of the vehicle-mounted player by sequentially setting an outer sealing ring, a side sealing ring, and an inner sealing ring between the player's outer casing and the touch screen. Furthermore, the two sides of the side sealing ring adopt an inclined mating structure with the outer and inner snap-fit ​​frames respectively, thereby effectively extending the sealing length within a limited space. This prevents moisture from entering the inside of the player's outer casing and corroding the electronic components on the PCB board, thus helping to ensure the service life of the vehicle-mounted player.

[0037] As a further improvement to this utility model, a sponge ring 14 is provided between the inner peripheral wall of the player housing 1 and the outer peripheral wall of the side sealing ring 5. The sponge ring 14 has a certain water absorption capacity, thereby absorbing the moisture that has permeated through the side sealing ring. In addition, the sponge ring is compressed between the player housing 1 and the side sealing ring, which will generate reverse pressure on the side sealing ring, making the side sealing ring tightly abut against the outer snap-fit ​​frame and the inner snap-fit ​​frame. The inclined structure on the opposite side of the outer snap-fit ​​frame and the inner snap-fit ​​frame will further press the side sealing ring, so that the two inner sidewalls of the side sealing ring are in close contact with the upper and lower surfaces of the touch screen near the outer edge, thereby further improving the waterproof sealing performance.

[0038] In addition, the player housing 1 is fixedly provided with a water-blocking cover 15 perpendicular to the upper part of the touch screen 3. The water-blocking cover 15 can, to a certain extent, prevent external water stains from falling directly onto the touch screen 3.

[0039] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
