[0035] The embodiments of the present application will be mainly described below with reference to the accompanying drawings of the specification.
[0036] In a first aspect, with reference to Figure 2 and Figure 4 , the present application provides a dust cover 100b, including a dust cover body 110 and a support protrusion 120. The dust cover body 110 has opposite inner and outer sides; the support protrusion 120 is provided on the outer side of the dust cover body 110, and there are at least three support protrusions 120, and all the support protrusions 120 can jointly support and abut against the inner side of the dust cover body 110 of another dust cover 100b.
[0037] In the present application, the dust cover 100b is provided with at least three support protrusions 120 on the dust cover body 110. When multiple dust covers 100b are stacked, between two adjacent dust covers 100b, the support protrusions 120 of the lower dust cover 100b can support the dust cover body 110 of the upper dust cover 100b, so that there is a gap between the dust cover bodies 110 of two adjacent dust covers 100b, thereby overcoming the influence of burrs, static electricity, etc., avoiding mutual adhesion, making it easier to pick up a single dust cover 100b, improving the automation degree of picking up the dust cover 100b, and improving the assembly efficiency of the audio device. In addition, at least three support protrusions 120 of the lower dust cover 100b jointly support the dust cover body 110 of the upper dust cover 100b, making the stacked multiple dust covers 100b relatively stable, not easy to shake or even scatter.
[0038] It can be understood that, referring to Figure 1 , in the related art, the dust covers 100a are directly stacked, and the contact area between adjacent dust covers 100a is large, which is easily affected by burrs, static electricity, etc., resulting in mutual adhesion; while in the present application, referring to Figure 4 , the contact between adjacent dust covers 100b changes from surface-to-surface contact to point-to-surface contact, thereby being able to overcome the influence of burrs, static electricity, etc., and avoiding mutual adhesion.
[0039] It should be noted that if the support protrusion 120 is one or two, it will cause the problem of unstable stacking. Therefore, there are three or more support protrusions 120 in the present application. Further explanation, the dust cover 100b in the present application is mainly provided on the audio device. The sound generating unit of the audio device needs to vibrate at a high frequency to generate sound. This requires minimizing the support protrusion 120 as much as possible, minimizing the sound wave energy loss caused by the vibration of the support protrusion 120, and minimizing audio distortion. Therefore, the preferred number of the support protrusions 120 in the present application is three, which can not only play a role in stable support and prevent adhesion, but also minimize audio distortion to the greatest extent.
[0040] In some embodiments, the support protrusion 120 is a hollow protrusion structure integrally provided with the dust cover body 110, and the wall thickness of the support protrusion 120 is the same as the wall thickness of the dust cover body 110.
[0041] In this embodiment, the support protrusion 120 is a hollow protrusion structure, which is integrally formed with the dust cover body 110 and has the same wall thickness, making it easy to manufacture and avoiding stress concentration. In addition, the support protrusion 120 can also be a solid protrusion structure. For example, after the dust cover body 110 is manufactured, a solid protrusion structure is formed by applying glue to its outer side surface, which can also achieve the purpose of supporting another dust cover 100b and is also within the protection scope of this application. However, compared with the hollow protrusion structure, the solid protrusion structure has cumbersome manufacturing steps, high production costs, and large energy loss during vibration after being installed on the audio device, which easily leads to audio distortion.
[0042] Specifically, when the dust cover 100b is manufactured, it needs to be heated and baked. If the wall thickness of the support protrusion 120 is inconsistent with that of the dust cover body 110, it will cause uneven dehydration during local baking and result in defective products.
[0043] Refer to Figure 2 and Figure 3 , in some embodiments, the maximum outer diameter of the support protrusion 120 is φ, where 0.5 mm ≤ φ ≤ 2 mm. In some embodiments, the dust cover body 110 has an arc surface structure, and all the support protrusions 120 are on the same circumference of the arc surface structure, and the protrusion heights of the respective support protrusions 120 are the same. In some embodiments, the height of the support protrusion 120 is h, and the wall thickness of the support protrusion 120 is δ, where δ ≤ h ≤ 2δ. In some embodiments, the plane at half the height of the dust cover body intersects the dust cover body 110 to form a first circumference C, and all the support protrusions 120 are on the first circumference C. In some embodiments, all the support protrusions 120 are evenly spaced along the first circumference C.
[0044] In the above embodiment, the outer diameter of the support protrusion 120 gradually decreases in the direction of the protrusion vertex. The maximum outer diameter and the protrusion height of the support protrusion 120 should be within a suitable range, neither too large nor too small. If the maximum outer diameter of the support protrusion 120 is too small and / or the protrusion height is too large, the support protrusion 120 is likely to be deformed under the influence of gravity when the dust covers 100b are stacked; if the maximum outer diameter of the support protrusion 120 is too large, resulting in a relatively large contact area between the protrusion vertex and another dust cover body 110, and / or the protrusion height is too small, it cannot achieve a good anti-adhesion effect.
[0045] It can also be understood that, refer to Figure 3, a support reference plane S is made through the protruding vertices of all the support protrusions 120, and an anti-adhesion gap is formed between the support reference plane S and the outer side surface of the dust-proof cover body 110. When the dust-proof cover body 110 has an arc surface structure, all the support protrusions 120 can also be located on different circumferences of the arc surface structure, and the protruding heights of the respective support protrusions 120 are different, as long as it can ensure that the protruding vertices of all the support protrusions 120 are used as the support reference plane S. Therefore, this embodiment also falls within the protection scope of the present application.
[0046] However, compared with the foregoing embodiment, the support protrusions 120 with equal protruding heights are uniformly spaced along the first circumference C, which is more conducive to dispersing the support force, making the support more stable, and the structural standard is also more convenient for the preparation of the dust-proof cover 100b. Specifically, the three support protrusions 120 are distributed at intervals of 120° on the first circumference C. Refer to Figure 4 , during actual stacking, it is necessary to rotate 30° between two adjacent dust-proof covers 100b, so that only point contact is generated between the inner side surface of the previous dust-proof cover 100b and the outer side surface of the next dust-proof cover 100b, avoiding the stacking of the hollow protrusion structures of the support protrusions 120, thereby effectively solving the influence of electrostatic adsorption or burr adhesion of the dust-proof cover 100b and realizing the uniqueness of the number of each material taking.
[0047] In some embodiments, refer to Figure 3 , the axis lines of all the support protrusions 120 are parallel to the axis line of the dust-proof cover body 110.
[0048] In this embodiment, refer to Figure 3 , taking the axis line of the dust-proof cover body 110 as the first axis line L1 and the axis line of the support protrusion 120 as the second axis line L2, then L1 and L2 are parallel, that is, the protruding directions of the dust-proof cover body 110 and the support protrusions 120 are the same, which is convenient for the dust-proof cover 100b to be taken out of the mold during the preparation of the dust-proof cover 100b, improving the production efficiency.
[0049] In a second aspect, the present application further provides an audio device, including a sound generating unit and the dust-proof cover 100b in the first aspect, and the dust-proof cover 100b is covered outside the sound generating unit.
[0050] In a third aspect, the present application further provides a vehicle, including a vehicle body and the audio device in the second aspect, and the audio device is installed on the vehicle body.
[0051] It can be understood that the audio device in the second aspect and the vehicle in the third aspect both include the dust-proof cover 100b in the first aspect. Therefore, the audio device in the second aspect and the vehicle in the third aspect at least have all the technical effects of the dust-proof cover 100b in the first aspect, and the technical effects of the dust-proof cover 100b have been described above and will not be repeated here.
[0052] It can also be understood that the dust cover 100b of the first aspect can also be provided on other electronic devices other than audio devices. Similarly, the audio device of the second aspect can also be provided on other means of transportation or household products other than vehicles.
[0053] In addition, the embodiments of the present application only illustrate the structures related to the improvement points of the present application in the audio device of the second aspect and the vehicle of the third aspect, but it does not mean that the two do not have other structures. For example, the audio device further includes a sound generating unit protective shell, and the vehicle further includes a sound generating power supply unit, etc. Other structures will not be elaborated here one by one.
[0054] In particular, it needs to be emphasized again that although the above content describes the embodiments of the present application in conjunction with the drawings, those skilled in the art can still make various modifications and variations without departing from the concept of the present application, and such modifications and variations fall within the scope defined by the present application.
