Description

Technical Field

[0001] The utility model relates to the field of automotive machines, in particular to a device for converting an automotive machine into a waterproof machine. Background Technique

[0002] Nowadays, with the improvement of people's living standards, means of transportation such as cars, motorcycles, and marine vessels are becoming more and more widespread, providing a lot of convenience for people to go out. While the means of transportation bring convenience, people also want to install multimedia speakers on these outdoor devices to eliminate fatigue during the journey. Generally, there are two installation structures for existing automotive machines:

[0003] Please refer to Figure 8 , the first semi - set method: The semi - set 2 is inserted into the instrument panel 1. Use a screwdriver to press the lugs on the semi - set 2 outwards so that it is stuck on the instrument panel 1. The main unit 3 is inserted into the semi - set 2. The semi - set 2 limits the main unit 3 in the up - down, left - right directions. The lugs on the semi - set 2 are inserted into the corresponding holes of the main unit 3, and the semi - set 2 also limits the main unit 3 in the front - back direction. Then, the decorative frame 4 is put on the main unit 3, and the installation is successful.

[0004] Please refer to Figure 9 , the second left - right bracket method: Use screws 6 to fix the left - right brackets 5 on the main unit 3. Open the instrument panel 1 and fix the main unit 3 to the vehicle platform through the left - right brackets 5. Cover the instrument panel 1, and then put the decorative frame 4 on the main unit 3, and the installation is successful.

[0005] For the above two installation methods of traditional in - vehicle multimedia players, corresponding holes need to be opened on the main unit 3, so they are not waterproof. Therefore, the in - vehicle player cannot be directly installed on means of transportation such as motorcycles and marine vessels that are in contact with water. For this reason, it is necessary to develop a multimedia player that is compatible with automotive and marine waterproofing. So, how to design an automotive machine with a lower cost and waterproof effect has become an urgent problem for those skilled in the art. Summary of the Utility Model

[0030] Please refer to Figures 1 to 7 , a device for converting an automotive machine into a waterproof machine is provided, including a main unit 3, a conversion frame 8 and an instrument panel 1. The conversion frame 8 is sleeved on the front end of the main unit 3, and the conversion frame 8 and the main unit 3 are fixed together by a second screw 7. The instrument panel 1 is sleeved outside the conversion frame 8, and the instrument panel 1 is fixed to the conversion frame 8 by a third screw 13. The main unit 3 is provided with left and right covers 14 to hide the third screw 13. A large rubber frame 15 is provided at the connection between the main unit 3 and the conversion frame 8. A groove is provided at the peripheral gap of the large rubber frame 15, and the groove is sealed by a sealing ring 9. The left and right side ends of the main unit 3 are pasted with a PET sheet 11 with single-sided adhesive, and a waterproof tape 10 is also wrapped outside the main unit 3.

[0031] The main unit 3 includes a top cover 16, a U-shaped frame 17 and a rear frame 21. The top cover 16, the U-shaped frame 17 and the rear frame 21 together form a space with only one opening at the front end. The main unit 3 is provided with a VOL knob 19, a button 20 and a TFT screen 18 at the front end. The VOL knob 19, the button 20 and the TFT screen 18 are all used to control and display the playback content of the automotive machine.

The VOL knob 19 is circular, and the button 20 is arranged around the VOL knob 19 for one week. The third screw 13 passes through the conversion frame 8 and is fixed to the vehicle-mounted platform. The conversion frame 8 is provided with corresponding threaded holes on the left and right sides.

[0032] Please refer to Figure 2 and Figure 7The instrument panel 1 is attached to the converter frame 8 with an EVA sheet 12. This EVA sheet 12 prevents external liquid from penetrating into the main unit 3 through the connection between the instrument panel 1 and the converter frame 8. The sealing ring 9 and the EVA sheet 12 form a two-layer waterproof structure, which is respectively fixed between the instrument panel 1, the converter, and the main unit 3.

[0033] A method for installing a device that converts a car machine into a waterproof machine:

[0034] See also Figure 2 , Step 1: Stick the single-sided adhesive PET sheet 11 on the host 3; Use double-sided tape to fix the sealing ring 9 in the groove of the large adhesive frame 15 of the host 3; Wrap the waterproof tape 10 around the host 3; Put the conversion frame 8 on the host 3, and lock the conversion frame 8 and the host 3 together with the second screw 7; Stick the single-sided adhesive EVA board 12 on the conversion frame 8.

[0035] See also Figure 3 , Step 2: Insert the main unit 3 assembled in the first step into the dashboard 1, fix the conversion frame 8 on the dashboard 1 with the third screw 13, and cover the left and right covers 14 to complete the general installation of the device.

[0036] To enable the use of the same main unit 3 for both the car model and the waterproof model, minimizing adaptation costs, the top cover 16 and U-shaped frame 17 of the main unit 3 should be free of holes other than the necessary mounting holes. The front nozzle must be waterproof (i.e., the buttons 20, VOL button 19, and TFT screen 18 must all be waterproof). The main unit 3's large plastic frame 15 has a groove for mounting the sealing ring 9.

[0037] Stick the single-sided adhesive PET sheet 11 on the main unit 3 to cover the left and right mounting holes; wrap the waterproof tape 10 around the main unit 3 to seal the gaps between the large adhesive frame 15, the U-shaped frame 17, and the top cover 16; after this processing, the main unit 3 can meet the IPX3-4 waterproof requirements.

[0038] Use double-sided tape to stick the sealing ring 9 into the groove of the large glue frame 15 of the main unit 3; put the conversion frame 8 on the main unit 3, and use the second screw 7 to lock the conversion frame 8 and the main unit 3 together; at this time, the sealing ring 9 fills the gap between the large glue frame 15 and the conversion frame 8 to achieve a waterproof effect.

[0039] Glue the single-sided adhesive EVA board 12 to the back of the conversion frame 8; insert the assembled host 3 into the dashboard 1, and use the third screw 13 to fix the conversion frame 8 on the host 3 to the dashboard 1. The EVA board 12 on the back of the conversion frame 8 is pressed against the dashboard 1, so that water cannot enter between the conversion frame 8 and the dashboard 1, thereby achieving a waterproof effect.

[0040] The utility model provides a device for converting an automotive machine into a waterproof machine. The decorative frame 4 in the prior art is changed to a conversion frame 8. An EVA board 12 is provided at the connection between the conversion frame 8 and the instrument panel 1. A large rubber mount 15 is provided at the connection between the main unit 3 and the conversion frame 8. A groove is provided on the large rubber mount 15 of the main unit 3, and a sealing ring 9 is filled in the groove. The EVA board 12 and the sealing ring 9 form a two-layer waterproof structure. Moreover, PET sheets 11 are provided on the left and right sides of the main unit 3. The PET sheets 11 also have good water seepage prevention functions, and a waterproof tape 10 is wrapped around the periphery of the main unit 3. In this way, even if water enters from the connection between the conversion frame 8 and the instrument panel 1, it cannot enter the interior of the main unit 3. With the cooperation of the multi-layer waterproof structure, even if it is installed on a water vehicle such as a motorboat, there is no fear of water penetrating into the main unit 3. Improvements are made on the structure of the prior art, reducing the cost caused by adaptation and achieving the purpose of waterproofing. The utility model has the characteristics of good waterproof effect and low cost.

[0041] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
