[0002] As living standards improve, more and more people own and use cars. Current cars are often equipped with microphones. Existing models typically use exposed active noise-cancelling microphones mounted on the headlining. The microphone is secured to a microphone holder, which is attached to the headlining via a mounting bracket. Typically, the microphone holder and mounting bracket are clipped together. When the vehicle vibrates, there's a risk that the connection between the microphone holder and mounting bracket will loosen, potentially affecting the proper function of the microphone. Utility Model Content

[0003] The present application provides a vehicle body and a car having the same, which are used to solve the problem that when a microphone holder is connected to a mounting frame and the vehicle vibrates, the microphone becomes loose and affects normal operation.

The main body has a first end face and a second end face along its thickness, the second end face facing the passenger compartment, the main body is provided with a mounting groove recessed from the first end face toward the second end face, the bracket is fixed to the main body, and a portion of the bracket is located in the mounting groove. The bottom wall of the mounting groove is provided with a first sound-transmitting hole extending through the second end face, the bracket is provided with a second sound-transmitting hole, and the first sound-transmitting hole is connected to the second sound-transmitting hole.

[0005] In this embodiment of the present application, the microphone is secured to a bracket, which is secured to the body and partially located in the mounting slot. A first sound-transmitting hole and a second sound-transmitting hole are provided in the body and bracket, respectively. The bracket abuts against the bottom wall of the mounting slot, allowing the first sound-transmitting hole to communicate with the second sound-transmitting hole. This allows the user to transmit sound into the microphone through the first and second sound-transmitting holes.

[0006] Therefore, when the microphone assembly is installed on the vehicle body, a portion of the bracket is installed within the mounting groove, allowing the microphone assembly to be directly mounted on the vehicle body. This enhances the stability of the microphone assembly when mounted on the vehicle body and reduces the risk of the bracket loosening due to vehicle vibration, allowing the microphone to function properly. Furthermore, there is no need to provide additional mounting structures for the microphone assembly, thereby simplifying the vehicle body structure. For example, in this embodiment, when installing the microphone assembly, there is no need to provide an additional decorative cover in the mounting groove to cooperate with the bracket. This prevents the decorative cover from being exposed in the passenger compartment and affecting the aesthetics of the vehicle body. Furthermore, there is no need to develop a structure for the decorative cover, which reduces costs and eliminates the need to consider after-sales issues with the decorative cover, thereby reducing management costs.

[0008] In a specific embodiment, the bracket includes a connecting portion and a matching portion, the matching portion is installed in the mounting slot and abuts against the bottom wall of the mounting slot, the microphone is installed in the matching portion, and the second sound hole is arranged at the bottom of the matching portion.

[0009] In a specific embodiment, the connecting portion is located outside the installation groove, and the connecting portion is bonded to the body.

[0010] In a specific embodiment, the bottom of the connecting portion has a supporting rib, and the supporting rib abuts against the main body to form a glue-containing space between the connecting portion and the main body.

[0011] In a specific embodiment, the connecting portion is provided with at least one through hole communicating with the glue containing space.

[0012] In a specific embodiment, the plurality of through holes are evenly distributed along the same circumference, and the diameter of the circumference formed by the plurality of through holes is greater than or equal to 4 mm.

[0013] In a specific embodiment, along the radial direction of the installation slot, the side wall of the first sound-transmitting hole does not exceed the side wall of the second sound-transmitting hole, and the distance L between the side wall of the first sound-transmitting hole and the side wall of the second sound-transmitting hole satisfies: 0≤L≤2mm.

[0014] In a specific embodiment, the diameter D1 of the first sound-transmitting hole satisfies: 7 mm ≤ D1 ≤ 10 mm, and / or the depth H of the first sound-transmitting hole satisfies: 1 mm ≤ H ≤ 3 mm.

[0040] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0044] The present embodiment provides a vehicle body, comprising a roof lining 1 and a microphone assembly 2. The roof lining 1 has a main body 11, which is provided with a mounting slot 111. The microphone assembly 2 includes a microphone 22 and a bracket 21. The microphone 22 is mounted in the bracket 21, and the microphone assembly 2 is mounted in the mounting slot 111. The present application will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0045] Among them, such as Figure 1 、 Figure 2 and Figure 4As shown, the vehicle body includes a roof lining 1, which includes a main body 11. The main body 11 has a first end surface 113 and a second end surface 114 along its thickness. The second end surface 114 faces the passenger compartment of the vehicle body, and the first end surface 113 is opposite the second end surface 114 and faces the interior of the vehicle body. The main body 11 is provided with a mounting groove 111 that is recessed from the first end surface 113 toward the second end surface 114. The vehicle body also includes a microphone assembly 2, which includes a microphone 22 and a bracket 21 for mounting microphone 22. The bracket 21 of the microphone assembly 2 is fixed to the main body 11, and a portion of the bracket 21 is mounted within the mounting groove 111, allowing the microphone assembly 2 to be directly mounted on the main body 11. This enhances the stability of the microphone assembly 2 mounted on the vehicle body and reduces the risk of the bracket 21 loosening due to vehicle vibration, allowing the microphone 22 to function properly. Furthermore, there is no need to provide additional mounting structures for the microphone assembly 2, thereby simplifying the vehicle body structure.

[0046] For example, in this embodiment, when installing the microphone assembly 2, there is no need to additionally provide a decorative cover in the installation groove 111 to cooperate with the bracket 21, thereby avoiding the decorative cover being exposed in the passenger compartment and affecting the aesthetics of the vehicle body. There is no need to further develop the structure of the decorative cover, thereby reducing costs, and there is no need to consider after-sales issues of the decorative cover, thereby reducing management costs.

[0047] The bottom wall of the mounting slot 111 is provided with a first sound-transmitting hole 112, which extends through the second end surface 114. The bracket 21 is provided with a second sound-transmitting hole 213, and the first sound-transmitting hole 112 and the second sound-transmitting hole 213 are connected and communicate with each other. When the microphone 22 is in use, the sound emitted by the microphone 22 can be transmitted to the passenger compartment through the connected second sound-transmitting hole 213 and the first sound-transmitting hole 112, allowing passengers to use the microphone 22.

[0048] In a specific embodiment, the mounting groove 111 and the first sound-transmitting hole 112 on the top lining 1 can be die-cut while the main body 11 is being formed, thereby improving processing efficiency.

[0049] In a specific embodiment, the bracket 21 and the main body 11 are bonded and fixed using structural adhesive. The structural adhesive has high strength and can be used to bond and fix two structural members. The bracket 21 is installed on the main body 11 and has the advantages of being structurally stable and firm, and the fixed connection can withstand various loads.

[0050] In other embodiments, other fixed connection methods may be used between the bracket 21 and the body 11, such as welding, riveting, bolt connection, etc.

[0051] In a specific embodiment, Figure 1 and Figure 2As shown, the bracket 21 includes a connecting portion 211 and a matching portion 212. The microphone 22 is fixedly installed in the matching portion 212. The matching portion 212 is installed in the mounting groove 111 and abuts against the bottom wall of the mounting groove 111. The second sound hole 213 is located at the bottom of the matching portion 212; the connecting portion 211 is bonded to the main body 11.

[0052] In this embodiment, the microphone 22 is mounted in the mating portion 212. The second sound-transmitting hole 213 at the bottom of the mating portion 212 communicates with the first sound-transmitting hole 112 at the bottom wall of the mounting slot 111, allowing sound from the microphone 22 to be transmitted through the first and second sound-transmitting holes 112, 213, enabling the microphone 22 to function properly. Furthermore, the abutment of the mating portion 212 against the bottom wall of the mounting slot 111 reduces the risk of sound leakage between the mating portion 212 and the bottom wall of the mounting slot 111. Furthermore, the connection portion 211 is bonded to the body 11, allowing the bracket 21 to be bonded and fixed to the body 11. Specifically, the bracket 21 is fixedly connected to the body 11 via the connection portion 211, eliminating the need for the mating portion 212, which is used to mount the microphone 22, to prevent the second sound-transmitting hole 213 of the mating portion 212 from being blocked when the mating portion 212 is fixed to the body 11. Furthermore, the connection portion 211, located outside the mounting slot 111, facilitates securing the bracket 21 to the body 11.

[0053] In some specific embodiments, such as Figure 1 As shown, the bracket 21 also has a support rib 214, which is arranged at the bottom of the connecting portion 211. The support rib 214 abuts against the body 11 to form a glue-containing space 3 between the connecting portion 211 and the body 11.

[0054] In this embodiment, the support rib 214 is raised relative to the connecting portion 211, and the bottom of the support rib 214 abuts against the main body 11, thereby forming a glue-containing space 3 between the connecting portion 211 and the main body 11 through the supporting effect of the support rib 214. The glue-containing space 3 is used to accommodate the glue used to bond the connecting portion 211 to the main body 11, so that there is enough glue used to bond the connecting portion 211 to the main body 11, thereby improving the bonding reliability of the connecting portion 211 and the main body 11. At the same time, the provision of the glue-containing space 3 can also prevent the glue from solidifying and lifting the bracket 21, causing the second sound-transmitting hole 213 to be away from the first sound-transmitting hole 112, resulting in sound leakage, thereby improving the user experience of the microphone 22.

[0055] In one specific embodiment, the support rib 214 provided on the bracket 21 may be an annular support rib 214 that can surround the bracket 21 in a direction perpendicular to the thickness. In other embodiments, the connection portion 211 may also be provided with multiple support ribs 214 at intervals. This application does not limit the specific structure of the support rib 214, as long as it can form the glue-containing space 3 between the connection portion 211 and the body 11.

[0056] Specifically, the width W of the support rib 214 satisfies 2mm≤W≤3mm, and the height can be 1mm-2mm.

[0057] In other embodiments, the supporting ribs 214 may also be provided on the main body 11 , so that a glue-containing space 3 is formed between the main body 11 and the connecting portion 211 .

[0058] In a specific embodiment, Figure 3 As shown, at least one through hole 2111 communicating with the glue containing space 3 is provided on the connecting portion 211 .

[0059] In this embodiment, through-hole 2111 is provided on connecting portion 211. When microphone 22 is mounted on the vehicle body, adhesive can enter adhesive-receiving space 3 through through-hole 2111, thereby achieving adhesion between connecting portion 211 and body 11. Furthermore, when through-hole 2111 is provided on connecting portion 211, it is not necessary to provide through-hole 2111 in body 11 of headliner 1. This maintains the integrity of body 11 and enhances the appearance of the vehicle body.

[0060] In some embodiments, the connecting portion 211 can be provided with two or more through holes 2111. In this case, the glue can enter the glue space 3 from a part of the through holes 2111, and the air and excess glue can pass through another part of the through holes 2111, thereby reducing the risk of the bracket 21 being lifted up due to the increase of air pressure in the glue space 3 and / or excessive glue in the glue space 3 during the glue injection process, thereby preventing the matching portion 212 and the bottom wall of the installation groove 111 from having a gap, causing sound leakage from the microphone 22.

[0061] In a specific embodiment, Figure 3 As shown, the plurality of through holes 2111 are evenly distributed along the same circumference, so that the distance between each through hole 2111 and the mating portion 212 is the same, thereby evenly distributing the adhesive in the adhesive space 3 and improving the adhesive bonding reliability between the bracket 21 and the body 11. The diameter of the circumference formed by the plurality of through holes 2111 is greater than or equal to 4 mm. For example, the diameter of the circumference formed by the plurality of through holes 2111 can be 4 mm, 4.5 mm, 5 mm, 6 mm, etc.

[0062] If the diameter of the circle formed by the multiple through holes 2111 is too small, the distance between the through holes 2111 and the second sound-transmitting hole 213 of the mating portion 212 is too small, creating a risk that adhesive entering through the through holes 2111 will flow toward the second sound-transmitting hole 213, blocking the hole. Furthermore, there's a risk that adhesive will leak onto the first end surface 113, impacting the appearance. In this embodiment, the diameter of the circle formed by the multiple through holes 2111 is no less than 4 mm, increasing the distance between the through holes 2111 and the second sound-transmitting hole 213 of the mating portion 212. This prevents adhesive entering through the through holes 2111 from clogging the second sound-transmitting hole 213, ensuring proper operation of the microphone 22. Furthermore, this prevents adhesive from leaking out of the first sound-transmitting hole 112 and flowing toward the second end surface 114, impacting the appearance.

[0063] In a specific embodiment, Figure 1 As shown, along the radial direction of the mounting groove 111, the side wall of the first sound hole 112 does not exceed the side wall of the second sound hole 213, that is, the side wall of the first sound hole 112 is flush with the side wall of the second sound hole 213, or, the side wall of the first sound hole 112 is located radially inward of the side wall of the second sound hole 213, thereby avoiding the first sound hole 112 of the main body 11 blocking the second sound hole 213 of the bracket 21, thereby ensuring the normal operation of the microphone 22.

[0064] The distance L between the side wall of the first sound transmission hole 112 and the side wall of the second sound transmission hole 213 satisfies 0≤L≤2mm. For example, L can be 1mm, 1.2mm, 1.3mm, 1.5mm, 1.7mm, 1.8mm, 2mm, etc.

[0065] When the distance L between the sidewalls of the first sound transmission hole 112 and the sidewalls of the second sound transmission hole 213 is too large, the diameter of the first sound transmission hole 112 is too large, given a given size of the second sound transmission hole 213. This results in a reduced contact area between the mating portion 212 of the body 11 and the bottom wall of the mounting groove 111, affecting the connection reliability between the mating portion 212 and the mounting groove 111. Therefore, in this embodiment, when the distance L between the sidewalls of the first sound transmission hole 112 and the sidewalls of the second sound transmission hole 213 satisfies 0 mm ≤ L ≤ 2 mm, the first sound transmission hole 112 is prevented from obstructing the second sound transmission hole 213, and the connection reliability between the mating portion 212 of the bracket 21 and the mounting groove 111 of the body 11 is improved.

[0066] In a specific embodiment, Figure 4As shown, the diameter D1 of the first sound transmission hole 112 satisfies the following conditions: 7 mm ≤ D1 ≤ 10 mm, and the depth H of the first sound transmission hole 112 satisfies the following conditions: 1 mm ≤ H ≤ 3 mm. For example, the diameter D1 of the first sound transmission hole 112 can be 7 mm, 8 mm, 8.5 mm, 9 mm, 10 mm, etc. The depth H of the first sound transmission hole 112 can be 1 mm, 1.5 mm, 1.7 mm, 2 mm, 2.1 mm, 2.5 mm, 3 mm, etc.

[0067] If the diameter D1 of the first sound-transmitting hole 112 is too small, there is a risk of affecting the transmission of the sound of the microphone 22 to the passenger compartment. If the diameter D1 of the first sound-transmitting hole 112 is too large, the contact area between the mating portion 212 of the bracket 21 and the mounting slot 111 of the body 11 is too small, affecting the connection reliability of the mating portion 212 and the mounting slot 111. Moreover, if the diameter of the first sound-transmitting hole 112 is too large, it will affect the aesthetics of the body 11. In this embodiment, when the diameter D1 of the first sound-transmitting hole 112 is 7 mm ≤ D1 ≤ 10 mm, the diameter D1 of the first sound-transmitting hole 112 is moderate. While the first sound-transmitting hole 112 does not affect the sound output of the microphone 22, it also improves the connection reliability between the mating portion 212 of the bracket 21 and the mounting slot 111 and improves the aesthetics of the body 11.

[0068] If the depth H of the first sound transmission hole 112 is too small, improper force may be applied during the installation of the bracket 21, potentially damaging the headliner 1 body 11. If the depth H of the first sound transmission hole 112 is too large, the microphone 22 will be spaced away from the second end surface 114, potentially preventing the passenger's voice from passing through the first sound transmission hole 112 and reaching the microphone 22. In this embodiment, the depth H of the first sound transmission hole 112 is moderate, with 1mm≤H≤3mm. The distance between the microphone 22 and the second end surface 114 is close enough, allowing the passenger's voice to be better transmitted to the microphone 22, while also providing a more stable structure for the first sound transmission hole 112 of the body 11.

[0069] In the above embodiments, Figure 1 As shown, the roof lining 1 may further include a covering layer 12, which is fixedly connected to the second end face 114 and can cover the first sound hole 112, so that the user cannot see the first sound hole 112 and the microphone assembly 2 in the passenger compartment, thereby hiding the microphone assembly 2 inside the vehicle body and improving the aesthetics of the vehicle body. The covering layer 12 is made of knitted fabric. In addition, compared with the related art in which the microphone assembly 2 is installed by exposing a decorative cover on the outside of the roof lining 1, the installation method of the microphone assembly 2 in the embodiment of the present application can also avoid the exposed decorative cover affecting the appearance.

[0070] In this embodiment, the cover layer 12 completely blocks the first sound-transmitting hole 112, concealing the microphone 22. It also prevents color shift at the location of the first sound-transmitting hole 112 on the body 11. Furthermore, the user's voice can pass through the knitted fabric and be received by the microphone 22. The cover layer 12 does not require a sound-transmitting hole. As long as the distance between the microphone 22 and the human ear does not exceed 25 cm, the sound wave signal output by the microphone 22 will pass through the knitted fabric without affecting the noise reduction function of the microphone 22. Therefore, when the cover layer 12 is made of knitted fabric, it has the advantages of making the headliner 1 look refined and facilitating the operation of the microphone 22.

[0071] In other possible embodiments, the covering layer 12 may also be made of other materials, such as wool fabric. The present application does not specifically limit the material of the covering layer 12.

[0072] An embodiment of the present application also provides a car, which has a car body described in the above embodiments. The car body has a roof lining 1 that can hide the microphone 22, and there is no need to additionally set up a mounting frame to cooperate with the microphone 22. The sound-transmitting hole is blocked by the covering layer 12 of knitted fabric, and the microphone 22 can work normally.

[0073] The above description is merely a specific implementation of the embodiments of the present application, but the scope of protection of the embodiments of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of the present application shall be included in the scope of protection of the embodiments of the present application. Therefore, the scope of protection of the embodiments of the present application shall be based on the scope of protection of the claims.
