Aging-resistant automobile dust cover

Abstract

This utility model relates to the field of automotive dust cover technology, specifically an aging-resistant automotive dust cover, including a dust cleaning component and a dust filter component installed on the dust cleaning component. The dust cleaning component includes a protective side cover, and the interior of the protective side cover has an annular cavity. Six springs and pressure-boosting pads fixedly installed on the top of the six springs are fixedly installed at the bottom of the annular cavity. The bottom of the inner side of the protective side cover has multiple waveguide slots distributed in a circular pattern. By installing the dust cleaning component on the outside of the car horn and the dust filter component on the dust cleaning component, when the car horn sounds and causes dust in the air to accumulate on the outer filter, some of the dust that passes through the outer filter will enter the upper dust-boosting groove along the gaps and the lower dust-boosting groove. The pressure-boosting pads, under the action of the horn's vibration waves, work with the springs to move up and down along the annular cavity, ultimately effectively removing the dust that has passed through the filter and preventing excessive dust accumulation from contaminating the horn.

Technical Field

[0001] This utility model relates to the field of automotive dust cover technology, specifically an aging-resistant automotive dust cover. Background Technology

[0002] There are many automotive parts, and some of them require dust covers to improve protection during use. The diaphragm of a car horn is fragile, so it is essential to add a dust cover to the car horn to extend its lifespan.

[0003] When a car horn sounds, dust in the surrounding air gathers towards the dust cover. As the dust continues to increase, excessive dust can affect the propagation of the horn sound. At the same time, damp dust can also corrode the dust cover.

[0004] In view of this, an aging-resistant car dust cover was designed to solve the above problems. Utility Model Content

[0007] An aging-resistant automotive dust cover includes a dust removal assembly and a dust filter assembly mounted on the dust removal assembly. The dust removal assembly includes a protective side cover, and the interior of the protective side cover has an annular cavity. Six springs and pressure-boosting pads are fixedly installed at the bottom of the annular cavity. The bottom of the inner side of the protective side cover has multiple waveguide slots distributed in a circular pattern, and the waveguide slots are connected to the bottom cavity formed by the pressure-boosting pads and the protective side cover. The dust filter assembly includes a top cover disposed at the top of the protective side cover, an inner filter screen fixedly installed at the bottom of the top cover, and an outer filter screen fixedly installed at the top of the top cover.

[0008] In a preferred embodiment, the present invention may be further configured such that the dust filter assembly further includes a cover plate snapped onto the outside of the top cover, and the cover plate is fixedly installed on the top of the protective side cover;

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an aging-resistant automotive dust cover.

[0028] Example 1:

[0029] Combination Figures 1 to 5 As shown, the present invention provides an aging-resistant car dust cover, including a dust cleaning component 100 and a dust filter component 200 installed on the dust cleaning component 100. The dust cleaning component 100 is used to remove the filtered dust by wave vibration, and the dust filter component 200 is used to filter the dust in the air.

[0030] The dust removal assembly 100 includes a protective side cover 110, and the interior of the protective side cover 110 is provided with an annular cavity 120. Six springs 140 and pressure-boosting pads 130 are fixedly installed at the bottom of the annular cavity 120.

[0031] The bottom of the inner side of the protective cover 110 is provided with multiple waveguide slots 1101 distributed in a circular pattern, and the waveguide slots 1101 are connected to the bottom cavity formed by the pressure pad 130 and the protective cover 110.

[0032] The top of the protective cover 110 is provided with multiple upper dust collection grooves 1102 symmetrical to the lower dust collection groove 2203, and the outer wall of the protective cover 110 is provided with multiple dust discharge grooves 1103.

[0033] Multiple dust discharge ports 1103 are connected to the top cavity formed by the pressure pad 130 and the protective cover 110;

[0034] The dust filter assembly 200 includes a top cover 220 disposed at the top of the protective side cover 110, an inner filter 230 fixedly installed at the bottom of the top cover 220, an outer filter 240 fixedly installed at the top of the top cover 220, and a cover plate 210 snapped onto the outside of the top cover 220, and the cover plate 210 is fixedly installed at the top of the protective side cover 110.

[0035] The cover plate 210 is fitted and pressed onto the side of the outer filter screen 240;

[0036] The top of the protective side cover 110 is fixed to the bottom of the cover plate 210 by adhesive.

[0037] Specifically, the bottom of the protective cover 110 is fixed to the outside of the car horn with glue. When the car horn is blaring for a long time and dust in the air adheres to the outer filter 240, the pressure pad 130 vibrates due to the horn's vibration wave and reciprocates along the inner cavity of the annular cavity 120. During the vibration of the pressure pad 130, some of the airflow pressurized by the pressure pad 130 is squeezed outward along the gap 2202. The squeezed airflow is released from the filter holes of the outer filter 240, which can effectively remove the dust adhering to the outside of the outer filter 240. At the same time, the dust sucked into the annular cavity 120 due to pressure is also squeezed outward from the dust discharge slot 1103 by the reciprocating vibration of the pressure pad 130.

[0038] Example 2:

[0039] Combination Figure 4 and Figure 5 As shown, based on Embodiment 1, the top cover 220 has an arc-shaped slot 2201 inside, and a slit 2202 is provided in the middle of the top cover 220, while the arc-shaped slot 2201 is connected to the slit 2202. The bottom of the top cover 220 has multiple circumferentially distributed dust-collecting grooves 2203, and the multiple dust-collecting grooves 2203 are connected to the slit 2202.

[0040] Both the outer and inner walls of the top cover 220 are fixedly fitted with rubber layers.

[0041] Preferably, the lower surface of the outer filter 240 and the upper surface of the inner filter 230 are fixed to the top and bottom of the top cover 220 respectively by applying adhesive dots, and the outer filter 240 and the inner filter 230 have the same structure.

[0042] When too much dust accumulates on the outside of the external filter 240 and some dust is squeezed into the inside of the gap 2202, the dust, which is subjected to the action of the horn vibration wave, will be effectively discharged along the gap 2202, the lower dust collection groove 2203 and the upper dust collection groove 1102. Finally, under the vibration pressure of the pressure pad 130, the dust that has entered the annular cavity 120 will be squeezed out.

[0043] The working principle and usage process of this utility model are as follows: First, the cover plate 210 of the outer part of the snap-on top cover 220 is fixedly installed on the protective side cover 110 using glue, and the bottom end of the protective side cover 110 is fixed to the outside of the car horn using glue. Since the outer filter 240 is exposed, dust in the air will be blocked by the outer filter 240. Once too much dust accumulates on the outside of the outer filter 240 and causes dust to overflow, the overflowing dust will enter the gap 2202. Finally, the dust will enter the annular cavity 120 from the gap 2202, the lower dust collection groove 2203, and the upper dust collection groove 1102. As the horn sounds, the vibration wave generated by the sound will cause the pressure pad 130 to vibrate slightly. Finally, the slightly vibrating pressure pad 130 can effectively squeeze out the dust in the annular cavity 120. At the same time, the back pressure airflow can also clean the dust in the mesh of the outer filter 240.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
