A detachable car side door audio speaker cover and detachable method thereof

Abstract

The present invention discloses a detachable automobile side door audio speaker cover, comprising a cover body, a swivel, multiple sets of positioning components, and multiple sets of reset components. The detachable cover body allows a user to place the cover body into a mounting slot and then rotate the cover body to install it into an inner guard plate. Simultaneously, the cover body can be removed by rotating it in the opposite direction. This allows the cover body to be removed separately when cleaning is required, saving a significant amount of time spent disassembling the inner guard plate and facilitating widespread promotion and use. The positioning components cooperate with positioning holes to limit the position of the cover body, thereby limiting the angle of the cover body after installation into the inner guard plate. This prevents the cover body from becoming loose or even falling during vehicle operation, improves the stability of the cover body after installation, and makes the cover body more stable during use.

Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of automobile accessories, and in particular to a detachable automobile side door audio speaker cover and a detachable method thereof. Background Art

[0002] Auto parts are categorized into five main categories: engine parts, chassis parts, body and accessory parts, electrical and electronic products, and general parts. These include exterior components, interior components, drivetrain components, fuel lines, circuits, brake systems, chassis, doors, grilles, and more. Side door inner panels are also considered auto parts. These panels are often fitted with speaker covers that correspond to the side door speakers. These covers are typically integrally molded with the panel and feature corresponding ventilation holes or slots to ensure smooth sound transmission, making them a crucial component of the car.

[0003] However, currently, the audio speakers are generally arranged inside the car door near the bottom of the connection between the car door and the car body. When opening and closing the car door, the driver and passengers' feet are very likely to touch the audio speaker cover, which usually causes dust to accumulate on the cover. In rainy weather, when there is mud on the feet, it is very easy for the mud to enter the speaker cover. Because the existing car side door speaker cover is made of one piece with the car side door inner guard plate, it is necessary to clean the mud and dust that enter the speaker later. Even when cleaning, the entire inner guard plate needs to be removed for cleaning. The removal steps of the inner guard plate are relatively cumbersome, making it very inconvenient to clean when mud and other debris enter the speaker cover. Therefore, there is an urgent need to improve the existing car door speaker cover. Summary of the Invention

[0004] To this end, an embodiment of the present invention provides a detachable automobile side door audio speaker cover and a detachable method thereof to solve the problem that the existing automobile side door speaker cover is made integrally with the automobile side door inner guard plate, which makes disassembly troublesome and the speaker inconvenient to clean.

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0036] The following detailed description is an exemplary description and is intended to provide further detailed description of the present invention. Unless otherwise indicated, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.

[0037] Example 1

[0038] Embodiment 1 of the present invention provides a detachable car side door audio speaker cover, such as Figure 1 、 Figure 2 and Figure 3 As shown, the speaker cover includes a cover body 1, a rotating ring 11, multiple sets of positioning components and multiple sets of reset components.

[0039] The inner guard plate 2 of the vehicle side door is provided with a mounting groove 3, and the protective cover body 1 can be threadedly connected to the mounting groove 3. After the user places the protective cover body 1 into the mounting groove 3, the protective cover body 1 is rotated to install it into the inner guard plate 2. At the same time, the protective cover body 1 can be removed by rotating it in the opposite direction. When the protective cover body 1 needs to be cleaned, it can be removed separately for more convenient cleaning.

[0040] The rotating ring 11 is rotatably arranged on the outside of the protective cover body 1 , and a plurality of friction blocks are arranged on the surface of the rotating ring 11 to realize the driving of the rotating ring 11 .

[0041] A plurality of limiting sliding grooves 6 and a plurality of reset sliding grooves 13 are evenly arranged on the protective cover body 1 , and a plurality of positioning holes 5 are evenly arranged in the installation groove 3 .

[0042] Multiple groups of positioning components are respectively arranged in a one-to-one correspondence with multiple limiting slide grooves 6. One end of each group of positioning components is fixedly connected to the rotating ring 11, and the other end can be slidably passed through the limiting slide groove 6 and matched with the positioning hole 5 under the drive of the rotating ring 11;

[0043] Multiple groups of reset components are arranged in a one-to-one correspondence with multiple reset grooves 13. Each group of reset components includes a transmission block 12 and a spring reset mechanism. The spring reset mechanism is arranged on the inner side of the protective cover body 1 and is installed on the transmission block 12. The transmission block 12 passes through the reset groove 13 and is fixedly connected to the swivel 11. The rotation of the swivel 11 can drive the rotation of the transmission block 12 and the compression of the spring reset mechanism, and can realize the automatic reset of the swivel 12 under the action of the restoring force of the spring reset mechanism.

[0044] A method for disassembling a detachable automobile side door audio speaker cover according to this embodiment specifically includes the following steps:

[0045] When installing the speaker cover, first place the cover body 1 in the installation groove 3 and tighten it in the direction of the thread tightening. At the same time, rotate the swivel 11 so that the end of the positioning assembly is pulled into the limiting slide groove 6. The rotation of the swivel 11 will simultaneously drive the end of the transmission block 12 to slide in the reset slide groove 13, and compress the spring reset mechanism. After the cover body 1 is tightened, the swivel 11 is loosened. The swivel 11 returns to its original position under the action of the restoring force of the spring reset mechanism, and drives the end of the positioning assembly to be pushed out of the limiting slide groove 6 and cooperate with the positioning hole 5 to fix the speaker cover.

[0046] When removing the speaker cover, first rotate the swivel 11 in the opposite direction so that the end of the positioning assembly is pulled out of the positioning hole 5 to release the fixation of the speaker cover. At the same time, the rotation of the swivel 11 will drive the end of the transmission block 12 to slide in the reset slide groove 13, and the spring reset mechanism will be compressed. When the end of the transmission block 12 slides to conflict with the inner wall of the reset slide groove 13, the swivel 11 can no longer rotate. Continuing to rotate the swivel 11 in the opposite direction with force will cause the cover body 1 to be rotated in the opposite direction and screwed out of the mounting groove 3. After loosening the swivel 11, the swivel 11 returns to its original position under the action of the restoring force of the spring reset mechanism, and drives the end of the positioning assembly to be pushed out of the limiting slide groove 6 again.

[0047] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the positioning assembly specifically includes a positioning block 4, a first spring 7 and a pull rope 9. One end of the first spring 7 is connected to the positioning block 4 and the other end is connected to the swivel 11. The pull rope 9 is arranged inside the first spring 7. One end of the pull rope 9 is connected to the positioning block 4 and the other end is connected to the swivel 11. The positioning block 4 can be pushed into the positioning hole 5 to fix the speaker cover. When the swivel 11 is rotated, the positioning block 4 is pulled out of the positioning hole 5 under the action of the pull rope 9 to release the fixation of the speaker cover.

[0048] The spring return mechanism includes a limit rod 14 and two groups of second springs 15. The limit rod 14 passes through the through hole in the middle of the transmission block 12. The two groups of second springs 15 are respectively arranged on both sides of the limit rod 14. One end of the two groups of second springs 15 is fixedly connected to the cover body 1 and the other end is in conflict with the transmission block 12. When the swivel 11 is rotated to pull the end of the positioning assembly out of the positioning hole 5 and completely enter the limiting slide groove 6, the end of the transmission block 12 is in conflict with the inner wall of the reset slide groove 13 to limit the rotation of the swivel 11. At the same time, one of the groups of second springs 15 is compressed. When the swivel 11 is released, the swivel 11 returns to its original position under the action of the restoring force of the compressed second spring 15, and can drive the positioning block 4 to be re-pushed out of the limiting slide groove 6.

[0049] Because the mounting groove 3 is provided with a positioning hole 5 corresponding to the positioning block 4, when the positioning block 4 corresponds to the positioning hole 5, the positioning block 4 can be pushed into the positioning hole 5, so that it cooperates with the positioning hole 5 to limit the position of the protective cover body 1, so that after the protective cover body 1 is installed in the inner guard plate 2, its angle will be limited, thereby preventing the protective cover body 1 from loosening or even falling during the operation of the vehicle, improving the stability of the protective cover body 1 after installation, and at the same time, when the protective cover body 1 is installed in the mounting groove 3, the positioning block 4 and the positioning hole 5 will be aligned. Correspondingly, it is convenient to push the positioning block 4 into the positioning hole 5, and because the end corners of the positioning block 4 are designed with arc-shaped rounded corners, it is easier for it to enter the positioning hole 5. Because a first spring 7 connected to the positioning block 4 is installed in the protective cover body 1, the positioning block 4 will squeeze the first spring 7 when entering the protective cover body 1, so that when the protective cover body 1 is installed in the inner cover, the first spring 7 will push the positioning block 4 into the positioning hole 5, so that the positioning block 4 will automatically restrict the protective cover body 1, making the protective cover body 1 more convenient to install.

[0050] A pull rope 9 is fixedly installed at the end of the positioning block 4 located inside the protective cover body 1, so that any one of the positioning block 4 and the pull rope 9 will drive the other to move synchronously when moving. A swivel 11 connected to the pull rope 9 is rotatably installed on the outer wall of the protective cover body 1, so that when the swivel 11 rotates, it will pull the pull rope 9, causing the pull rope 9 to start pulling the positioning block 4 to move into the protective cover body 1, so that the positioning block 4 will be separated from the positioning hole 5, so that when the protective cover body 1 needs to be removed, the restriction imposed on the protective cover body 1 by the positioning block 4 can be released by rotating the swivel 11, thereby making it convenient for the user to remove it, and because multiple sets of friction blocks are installed on the outer wall of the swivel 11, it is convenient for the user to rotate the swivel 11.

[0051] In this embodiment, the cross-section of the positioning block 4 is designed to be T-shaped. When the outer end of the positioning block 4 enters the positioning hole 5, the limiting end of the positioning block 4 located in the limiting chute 6 will interfere with the inner wall of the limiting chute 6 to prevent the positioning block 4 from being completely pushed out of the limiting chute 6. Because the cross-section of the positioning block 4 is designed to be T-shaped, when the positioning block 4 slides into the positioning hole 5 and its end fully enters the positioning hole 5, the outer wall of the end of the positioning block 4 located in the limiting chute 6 will interfere with the inner wall of the limiting chute 6, resulting in the length of the positioning block 4 that can slide out of the limiting chute 6 being limited, preventing the positioning block 4 from being completely pushed out of the limiting chute 6 by the first spring 7.

[0052] In this embodiment, a fixing bolt 16 is provided through the transmission block 12, the end of which is threadedly connected to the swivel 11. The limiting rod 14 is provided with an arcuate groove 17 for the sliding movement of the fixing bolt 16. In this embodiment, the end of the first spring 7 is fixedly connected to the swivel 11 via the mounting plate 8. A strong magnetic block 10 is mounted on the end of the pull rope 9. The swivel 11 is provided with a slot 101 that mates with the strong magnetic block 10. The inner wall of the slot 101 is made of magnets that are magnetically attracted to the strong magnetic block 10.

[0053] In this embodiment, a plurality of limiting slots 6 are provided at equal angles in the protective cover body 1, and a positioning block 4 is provided in each limiting slot 6, so that the protective cover body 1 will be restricted by multiple groups of positioning blocks 4 and positioning holes 5, further ensuring the angle fixity of the protective cover body 1 after installation, and a mounting plate 8 bolted to the protective cover body 1 is installed at the end of the limiting slot 6, and the end of the mounting plate 8 is connected to the first spring 7, so that when the first spring 7 is squeezed by the positioning block 4, the mounting plate 8 will block the first spring 7, thereby ensuring that the first spring 7 can smoothly contract after being squeezed, ensuring that it can smoothly push the positioning block 4 outward subsequently, and at the same time, because the mounting plate 8 is installed in the outer wall of the protective cover body 1 by bolts, the mounting plate 8 can be removed by removing the bolts, and the first spring 7 that has lost its elasticity can be replaced, which is convenient for subsequent maintenance.

[0054] The swivel 11 is connected to the pull rope 9 by the center of the mounting plate 8, so that the pull rope 9 can pass through the center of the mounting plate 8 smoothly, thereby ensuring that the pull rope 9 can be smoothly pulled when the swivel 11 rotates. At the same time, a strong magnetic block 10 is installed at the end of the pull rope 9, and a slot 101 matching the strong magnetic block 10 is opened on the outer wall of the swivel 11, and the inner wall of the slot 101 is made of magnets that are magnetically attracted to the strong magnetic block 10, so that after the strong magnetic block 10 enters the slot 101, the strong magnetic block 10 will be engaged with the slot 101, and the strong magnetic block 10 will also be magnetically attracted to the slot 101, thereby increasing the fixity of the engagement between the strong magnetic block 10 and the slot 101, ensuring that the strong magnetic block 10 will not be separated from the slot 101 when the swivel 11 rotates, and at the same time ensuring that the swivel 11 can be separated from the strong magnetic block 10 when it is pulled outward.

[0055] In this embodiment, a fixing bolt 16 is slidably installed in the transmission block 12, so that the fixing bolt 16 can be removed from the transmission block 12, and the end of the fixing bolt 16 is threadedly connected to the swivel 11, so that the connection and fixation between the swivel 11 and the transmission block 12 are achieved by the fixing bolt 16. When the swivel 11 needs to be removed, the fixing bolt 16 is separated from the swivel 11 to access the connection between the transmission block 12 and the swivel 11, which is convenient for the subsequent removal of the swivel 11, and an arc-shaped groove 17 for the sliding of the fixing bolt 16 is opened through the outer wall of the limit rod 14, so that when the transmission block 12 rotates, the fixing bolt 16 can rotate in the arc-shaped groove 17, ensuring that the setting of the fixing bolt 16 will not cause the transmission block 12 to be unable to rotate.

[0056] In this embodiment, a ventilation groove is provided on the protective cover body 1 to ensure that after the protective cover body 1 is installed on the inner guard plate 2, the sound of the speaker can smoothly pass through the ventilation groove.

[0057] In this embodiment, a reset assembly connected to the swivel 11 is provided in the protective cover body 1, and multiple groups of reset assemblies are provided at equal angles in the protective cover body 1, and the reset assembly consists of a transmission block 12, a limit rod 14 and a second spring 15, wherein the transmission block 12 is slidably installed in the protective cover body 1, so that the transmission block 12 can slide in the protective cover body 1, and because the end of the transmission block 12 is connected to the swivel 11, the swivel 11 will drive the transmission block 12 to rotate synchronously when it rotates, and when the transmission block 12 moves, it will also drive the swivel 11 to rotate, and a limit rod 14 slidably connected to the transmission block 12 is installed in the protective cover body 1. Because the limit rod 14 is an arc rod design, the rotation trajectory of the transmission block 12 is restricted, so that the rotation of the swivel 11 will also be restricted, ensuring the stability of the swivel 11 during rotation.

[0058] Two second springs 15 connected to the protective cover body 1 are sleeved on the outer wall of the limiting rod 14, so that when the second spring 15 is squeezed, the protective cover body 1 will resist the second spring 15, so that the second spring 15 will shrink after being squeezed. At the same time, the limiting rod 14 will support the second spring 15 to prevent the second spring 15 from exploding outwards and being damaged after being squeezed, thereby extending the service life of the second spring 15. The ends of the two second springs 15 are in conflict with the transmission block 12, so that no matter whether the transmission block 12 rotates clockwise or counterclockwise When the swivel 11 is rotated, its outer wall will squeeze a second spring 15, so that when the user loosens the swivel 11, the corresponding second spring 15 will push the transmission block 12 back to its original position, ensuring that the swivel 11 can be smoothly reset after rotation, thereby ensuring that the positioning block 4 will lose the tension limit given by the pull rope 9, and because the transmission block 12 is only in contact with the second spring 15 instead of being fixedly connected, when it rotates toward one second spring 15, it will not pull the other second spring 15, thereby effectively preventing the accident of pulling the second spring 15 and reducing its service life.

[0059] The return slide 13 corresponding to the transmission block 12, the limit rod 14 and the second spring 15 is provided in the protective cover body 1, so that the return slide 13 corresponding to the transmission block 12, the limit rod 14 and the second spring 15 can be smoothly installed in the protective cover body 1. At the same time, the opening position of the return slide 13 is staggered with the installation position of the positioning block 4 to ensure that the arrangement of the transmission block 12, the limit rod 14, the second spring 15 and the return slide 13 will not affect the movement of the positioning block 4. At the same time, the return slide 13 will also limit the sliding of the transmission block 12, so that its rotation angle will be limited, so that the transmission block 12 can only rotate until the swivel 11 completely pulls the positioning block 4 into the limit slide 6, that is, it can no longer rotate. At this time, when the swivel 11 is continued to be rotated, the swivel 11 will drive the protective cover body 1 to rotate.

[0060] Example 2

[0061] This embodiment differs from the first embodiment in that a retaining ring 18 is mounted on the inner wall of the protective cover body 1. The retaining ring 18 has a shielding portion extending toward the center of the protective cover body 1 to block dirt and debris. If a user accidentally bumps their foot against the protective cover body 1 when getting in or out of the vehicle, causing mud to enter the protective cover body 1, the retaining ring 18 will block the mud, greatly reducing the probability of mud or food crumbs entering the protective cover body 1 and entering the speaker, further improving the protective effect of the present protective cover body 1.

[0062] Specifically, the working principle of the present invention is as follows: when the inner guard plate 2 needs to be cleaned, the rotating ring 11 is rotated to drive the transmission block 12 to rotate, so that the transmission block 12 starts to squeeze the second spring 15. At the same time, the rotating ring 11 also pulls the positioning block 4 through the pull rope 9, so that the positioning block 4 starts to rotate toward the limiting chute 6. When the side wall of the transmission block 12 conflicts with the inner wall of the reset chute 13, the positioning block 4 has completely entered the limiting chute 6, so that the positioning block 4 gives the protective cover body 1 limited contact. Then, the rotating ring 11 is continued to be rotated to make the protective cover body 1 start to rotate, so that the protective cover body 1 is rotated out of the mounting groove 3.

[0063] When the protective cover body 1 needs to be installed, similarly to the above, the protective cover body 1 is rotated and threadedly installed in the installation groove 3, so that the positioning block 4 corresponds to the position of the positioning hole 5. At the same time, after the protective cover body 1 is installed, the user's hand can be separated from the rotating ring 11, so that it loses the power to rotate. At this time, the second spring 15 will push the rotating ring 11 back to its original position through the transmission block 12, so that the restriction imposed by the rotating ring 11 on the positioning block 4 is released. At this time, the positioning block 4 will slide into the positioning hole 5 under the action of the first spring 7, so that the protective cover body 1 will be restricted by the positioning block 4 and the positioning hole 5 and cannot continue to rotate, thereby preventing the protective cover body 1 from gradually loosening during the operation of the car.

[0064] When it is necessary to replace the first spring 7, the positioning block 4, the pull rope 9 or the swivel 11, first remove the cover body 1, then use a tool to remove the fixing bolt 16 to release the fixation between the swivel 11 and the transmission block 12, then rotate the position of the cover body 1 where the swivel 11 is installed to face the ground, so that the swivel 11 falls out of the cover body 1. If the swivel 11 cannot fall out at this time, you can use a flat-blade screwdriver or other tool to pass through the reset slot 13 and the arc slot 17 to push the swivel 11 to separate it from the strong magnetic block 10. At this time, the swivel 11 is removed and the mounting plate 8 will leak out. Then you can unscrew the bolts of the mounting plate 8 to release the fixation between it and the cover body.
