Description

Technical Field

[0001] This utility model relates to the field of automotive interiors, and more specifically, to a sealing and dustproof structure for automotive armrest boxes. Background Technology

[0002] The main functions of the sealed dustproof structure of a car's armrest box include dust and water protection, and protecting internal components. During daily driving, dust and fine particles can enter the car through gaps, affecting the cleanliness of the interior environment. The sealed dustproof structure of the armrest box effectively blocks these dust and particles, keeping the inside of the armrest box clean and reducing the frequency of cleaning.

[0003] Currently, most sealing and dustproof structures used in car armrest boxes have the following problems:

[0004] I. Existing sealing and dustproof structures for car armrest boxes mostly rely on adhesive sealing gaskets to seal and protect the gaps created when the armrest cover is closed. However, with prolonged use, the sealing gaskets are prone to oxidation and breakage. When the sealing gasket needs to be replaced, the adhesive area needs to be heated for subsequent removal and replacement, which is time-consuming and laborious, and makes it inconvenient to install and remove the sealing gaskets easily.

[0005] Second, existing sealing and dustproof structures for car armrest boxes can only rely on gaskets for sealing protection. If the gaskets are damaged, uneven sealing is likely to occur, making it inconvenient to provide multi-level protection and sealing for gaps.

[0006] Therefore, we have made improvements to this by proposing a sealed and dustproof structure for automotive armrest boxes. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in conveniently installing and removing sealing gaskets, and inconvenience in providing multi-level protective sealing for gaps.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A sealed, dustproof structure for car armrest boxes to improve the above-mentioned problems.

[0010] The application is as follows:

[0011] The device includes a mounting plate, to which a connecting hinge is bolted. An armrest cover is bolted to the connecting hinge. A fixing plate is mounted on the armrest cover. A sealing gasket is fixedly connected to the fixing plate. A locking block is fixedly connected to the fixing plate. A positioning plate is fixedly connected to the fixing plate. A first spring is fixedly connected inside the armrest cover. A limit plate is fixedly connected to the other end of the first spring. A positioning block is fixedly connected to the limit plate. A pull rod is fixedly connected to the limit plate. A sealing airbag is fixedly connected to the armrest cover. An air supply pipe is fixedly connected to the sealing airbag and is fixedly connected inside the armrest cover. A second spring is fixedly connected inside the armrest cover. A piston plate is fixedly connected to the other end of the second spring.

[0012] As a preferred technical solution of this application, the armrest covers are symmetrically distributed on the left and right sides of the mounting plate, and the armrest covers correspond one-to-one with the sealing gaskets through the fixing plates.

[0013] As a preferred technical solution of this application, the end cross-section of the positioning plate is inclined, and the side end face of the limiting plate is in contact with the inner side of the armrest cover.

[0014] As a preferred technical solution of this application, the positioning block has an isosceles triangle cross-section, and the end of the pull rod is fixedly connected to the center of one side of the limiting plate.

[0015] As a preferred technical solution of this application, a pressure rod is fixedly connected to the piston plate, and a magnetic block is fixedly connected to the pressure rod. The magnetic block has a semi-circular cross-section.

[0016] As a preferred technical solution of this application, the side end face of the piston plate is in contact with the inner side of the armrest cover, and the pressure rod is fixedly connected to the center of the piston plate and the magnetic block.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. A positioning plate is provided; when disassembling the sealing gasket, the pull rod can be pulled to move the limiting plate. When the limiting plate is pressed against the first spring, it can simultaneously move the positioning block. The positioning block disengages from the positioning plate and retracts into the armrest cover. The positioning plate and the locking block on the fixed plate can be disassembled and removed without obstruction. When replacing the sealing gasket, the positioning plate and the locking block on the fixed plate can be inserted into the armrest cover. Releasing the pull rod will push the limiting plate and the positioning block to reset under the push of the first spring. The positioning block can engage and fix the positioning plate, connecting the fixed plate and the sealing gasket, thus improving the efficiency of disassembly and installation.

[0020] 2. Equipped with a sealing airbag; when the armrest covers on both sides are closed, the sealing gaskets on both sides are in contact to seal, and at the same time, the magnetic blocks on the armrest covers are in contact with each other. When pressed down, the magnetic blocks can push the piston plate to move through the pressure rod. The piston plate can push the gas to inflate the sealing airbag through the gas supply pipe. When the piston plate moves, it can squeeze the second spring, which can provide multi-level sealing protection. Attached Figure Description

[0034] Example 1:

[0035] like Figure 1-7 As shown, this embodiment proposes a sealed and dustproof structure for an automotive armrest box, including a mounting plate 1, a connecting hinge 2 bolted to the mounting plate 1, an armrest cover 3 bolted to the connecting hinge 2, a fixing plate 4 on the armrest cover 3, a sealing gasket 5 fixedly connected to the fixing plate 4, a locking block 6 fixedly connected to the fixing plate 4, a positioning plate 7 fixedly connected to the fixing plate 4, a first spring 8 fixedly connected inside the armrest cover 3, a limiting plate 9 fixedly connected to the other end of the first spring 8, a positioning block 10 fixedly connected to the limiting plate 9, a pull rod 11 fixedly connected to the limiting plate 9, a sealing airbag 12 fixedly connected to the armrest cover 3, an air supply pipe 13 fixedly connected to the sealing airbag 12, the air supply pipe 13 fixedly connected inside the armrest cover 3, a second spring 14 fixedly connected inside the armrest cover 3, and a piston plate 15 fixedly connected to the other end of the second spring 14.

[0036] Example 2:

[0037] The solution in Example 1 will be further described below with reference to its specific working method.

[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, the armrest covers 3 are symmetrically distributed on the left and right sides of the mounting plate 1. The armrest covers 3 correspond one-to-one with the sealing gaskets 5 through the fixing plate 4, which can ensure the cooperation between the armrest covers 3 and the sealing gaskets 5 on both sides and play a protective sealing role.

[0039] like Figure 6 As shown, in a preferred embodiment, based on the above method, the end cross-section of the positioning plate 7 is inclined, and the side end face of the limiting plate 9 is in contact with the inner side of the armrest cover 3, which can ensure that the inclined surface of the positioning plate 7 can push the positioning block 10 to move and retract.

[0040] like Figure 6 As shown, in a preferred embodiment, based on the above method, the positioning block 10 has an isosceles triangle cross section, and the end of the pull rod 11 is fixedly connected to the center of one side of the limiting plate 9. This ensures that the inclined surface of the isosceles triangle positioning block 10 can be pushed by the positioning plate 7, and the plane of the positioning block 10 can be engaged in the positioning plate 7 for fixed positioning.

[0041] like Figure 7 As shown, in a preferred embodiment, based on the above method, a pressure rod 16 is fixedly connected to the piston plate 15, and a magnetic block 17 is fixedly connected to the pressure rod 16. The magnetic block 17 has a semi-circular cross-section, which ensures that when the semi-circular magnetic block 17 is in contact, rotation and pressing can play a pushing role.

[0042] like Figure 7 As shown, in a preferred embodiment, based on the above method, the side end face of the piston plate 15 is in contact with the inner side of the armrest cover 3, and the pressure rod 16 is fixedly connected to the center of the piston plate 15 and the magnetic block 17, which can ensure that the magnetic block 17 can drive the piston plate 15 to move and apply pressure through the pressure rod 16.

[0043] Specifically, the sealing and dustproof structure originally used for car armrest boxes, when in use: combined with Figure 1-7 When disassembling the sealing gasket 5, the pull rod 11 can be pulled to move the limiting plate 9. When the limiting plate 9 presses against the first spring 8, it can simultaneously move the positioning block 10. The positioning block 10 disengages from the positioning plate 7 and retracts into the armrest cover 3. The positioning plate 7 and the locking block 6 on the fixing plate 4 can be disassembled and removed without obstruction. When replacing the sealing gasket 5 and reinstalling, the positioning plate 7 and the locking block 6 on the fixing plate 4 can be inserted into the armrest cover 3. When the pull rod 11 is released, the limiting plate 9 and the positioning block 10 are reset under the push of the first spring 8. The positioning block 10 can engage and fix the positioning plate 7, connecting the fixing plate 4 and the sealing gasket 5, thus improving the efficiency of disassembly and installation.

[0044] Mounting plate 1 can be installed on the car armrest box. The connecting hinge 2 on mounting plate 1 can be connected to rotate armrest cover 3. When the armrest covers 3 on both sides are closed, the sealing gaskets 5 on both sides are in contact to seal. At the same time, the magnetic blocks 17 on the armrest cover 3 are in contact with each other. When pressed down, the magnetic blocks 17 can push the piston plate 15 to move through the pressure rod 16. The piston plate 15 can push the gas to inflate the sealing airbag 12 through the gas supply pipe 13. When the piston plate 15 moves, it can squeeze the second spring 14, which can provide multi-level sealing protection. When the armrest covers 3 on both sides are opened, the piston plate 15 is driven to return to its original position under the push of the second spring 14, and the gas in the sealing airbag 12 is discharged, which can facilitate the opening.

[0045] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of practicality, are covered within the scope of the claims of the present utility model.
