Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0022] As Figures 1 - 5 shown, a noise-reducing in-vehicle refrigerator includes a body 1; a sealed door 2 is hinged to the side end of the body 1; a drive housing 3 is fixedly connected to the side end of the body 1; a carrying handle 5 is installed at the top end of the drive housing 3; a refrigerator inner cavity 9 is opened inside the body 1; a heat dissipation fan 7 is fixedly connected inside the drive housing 3; a heat dissipation groove 6 is opened inside the drive housing 3; a noise reduction plate 8 is installed on the inner side wall of the drive housing 3; a first sound absorption cotton board 14 is fixedly connected to the inner side wall of the noise reduction plate 8; a second sound absorption cotton board 15 is provided on one side of the first sound absorption cotton board 14.

[0023] During operation, cold air is generated by the operation of the drive housing 3 to preserve the items inside the refrigerator inner cavity 9 at a low temperature. The user can open the sealed door 2 to place the items inside the refrigerator inner cavity 9. The drive housing 3 generates heat during operation, and this heat needs to be dissipated in time. The hot air flow will be discharged through the heat dissipation groove 6. The inside of the drive housing 3 can be in contact with the outside through the heat dissipation groove 6, resulting in the noise inside the drive housing 3 being discharged through the heat dissipation groove 6 as well, thus affecting the surrounding environment. The drive housing 3 can be heat-dissipated through the heat dissipation fan 7. When the noise is discharged through the heat dissipation groove 6, it will first contact the noise reduction plate 8, and the noise will be first absorbed by the first sound absorption cotton board 14. There are multiple groups of holes inside the first sound absorption cotton board 14, while the second sound absorption cotton board 15 is not provided with holes. The noise will flow and spread on one side of the second sound absorption cotton board 15 and then be absorbed by the second sound absorption cotton board 15, thereby reducing noise diffusion and avoiding the noise diffusion from affecting the driver.

[0024] A heat conduction plate 12 is fixedly connected inside the refrigerator inner cavity 9; a heat sink 11 is fixedly connected to the side end of the heat conduction plate 12; through holes 13 are opened inside the heat sink 11.

[0025] The heat conduction plate 12 is arranged inside the inner cavity 9 of the refrigerator. The inside of the inner cavity 9 of the refrigerator is a low-temperature environment. Through the heat conduction plate 12, the positioning environment can be transmitted and diffused to the heat sink 11. The heat sink 11 is arranged inside the drive housing 3. The high-temperature environment inside the drive housing 3 will be diffused to the heat sink 11. The heat sink 11 will be affected by the low temperature of the heat conduction plate 12, so as to dissipate heat from the heat sink 11, and then improve the heat dissipation effect of the drive housing 3. The air flow generated by the cooling fan 7 can contact the heat sink 11. The hot air flow inside the drive housing 3 contacts the heat sink 11 and then cools down, thereby improving the heat dissipation effect of the drive housing 3.

[0026] The top end of the noise reduction plate 8 is fixedly connected with a positioning plate 16; the inner side wall of the drive housing 3 is fixedly connected with a positioning card plate 17, and the inner side wall of the positioning card plate 17 is slidably connected with the positioning plate 16.

[0027] Before working, the noise reduction plate 8 is installed and fixed inside the drive housing 3, and the noise reduction plate 8 is slid to one side of the heat dissipation groove 6, so that the positioning plate 16 slides into the positioning card plate 17. The position of the positioning plate 16 is limited by the positioning card plate 17, and then the position of the noise reduction plate 8 is fixedly installed.

[0028] The bottom end of the machine body 1 is fixedly connected with a storage cabinet 4; a storage box is slidably connected inside the storage cabinet 4.

[0029] There is a storage box inside the storage cabinet 4. Excessive items can be placed in the storage box of the storage cabinet 4. The storage cabinet 4 is arranged at the bottom end of the machine body 1. The low-temperature environment inside the machine body 1 will be transmitted to the storage cabinet 4, thereby reducing the environment inside the storage cabinet 4 and providing more storage spaces with different temperatures.

[0030] A support plate 10 is fixedly connected inside the inner cavity 9 of the refrigerator, and the support plate 10 is arranged on one side of the sealing door 2.

[0031] Items can be stored at low temperature inside the inner cavity 9 of the refrigerator. The items can be placed on the support plate 10. The support plate 10 can limit the position of cylindrical items, so that the items will not swing randomly during the driving process of the vehicle.

[0032] A magnet sheet is fixedly connected to the inner side wall of the positioning card plate 17, and the magnet sheet is arranged on one side of the positioning plate 16.

[0033] When the positioning plate 16 slides to the inner side wall of the positioning card plate 17, the positioning card plate 17 will adsorb the positioning plate 16 through the magnetic attraction of the magnet sheet, thereby limiting the position of the positioning plate 16 and preventing the position of the positioning plate 16 from sliding randomly during the working process.

[0034] Working principle of the utility model: When working, the drive housing 3 operates to generate cold air for low-temperature preservation of items inside the refrigerator cavity 9. The user can open the sealed door 2 to place items inside the refrigerator cavity 9. When the drive housing 3 is working, heat is generated, and this heat needs to be dissipated in a timely manner. The hot air flow will be discharged through the heat dissipation slots 6. The inside of the drive housing 3 can be in contact with the outside through the heat dissipation slots 6, resulting in the noise inside the drive housing 3 being discharged through the heat dissipation slots 6 as well, thus affecting the surrounding environment. The drive housing 3 can be cooled by the heat dissipation fan 7. When the noise is discharged through the heat dissipation slots 6, it will first contact the noise reduction plate 8, and the noise will be first absorbed by the first sound-absorbing cotton board 14. There are multiple groups of holes inside the first sound-absorbing cotton board 14, while the second sound-absorbing cotton board 15 has no holes. The noise will flow and spread on one side of the second sound-absorbing cotton board 15 and then be absorbed by the second sound-absorbing cotton board 15, thereby reducing noise diffusion and preventing noise diffusion from affecting the driver. Before working, the noise reduction plate 8 is installed and fixed inside the drive housing 3, and the noise reduction plate 8 is slid to one side of the heat dissipation slots 6, so that the positioning plate 16 slides into the positioning card 17. The position of the positioning plate 16 is limited by the positioning card 17, and then the position of the noise reduction plate 8 is fixedly installed. When the positioning plate 16 slides to the inner side wall of the positioning card 17, the positioning card 17 will adsorb the positioning plate 16 through the magnetic attraction of the magnet sheet, thus limiting the position of the positioning plate 16 and preventing the positioning plate 16 from sliding randomly during the working process. Items can be stored at low temperature inside the refrigerator cavity 9. The items can be placed on the support plate 10, and the support plate 10 can limit the position of cylindrical items, so that the items will not sway randomly during vehicle driving. The heat conduction plate 12 is arranged inside the refrigerator cavity 9. The inside of the refrigerator cavity 9 is a low-temperature environment. Through the heat conduction plate 12, the positioning environment can be transmitted and diffused to the heat sink 11. The heat sink 11 is arranged inside the drive housing 3. The high-temperature environment inside the drive housing 3 will be diffused to the heat sink 11. The heat sink 11 will be affected by the low temperature of the heat conduction plate 12, thereby cooling the heat sink 11 and improving the heat dissipation effect of the drive housing 3. The air flow generated by the heat dissipation fan 7 can contact the heat sink 11. The hot air flow inside the drive housing 3 contacts the heat sink 11 and then cools down, thereby improving the heat dissipation effect of the drive housing 3. The air flow easily flows through the through holes 13. The storage cabinet 4 is provided with a storage box inside. Excessive items can be placed in the storage box of the storage cabinet 4. The storage cabinet 4 is arranged at the bottom end of the machine body 1. The low-temperature environment inside the machine body 1 will be transmitted to the storage cabinet 4, thereby reducing the environment inside the storage cabinet 4 and providing more storage spaces with different temperatures.
