[0041] The embodiments of the present application provide a roof structure, which can also be referred to as a roof lining, a roof liner, etc., and is an important component of the interior trim of a vehicle. The roof structure can have various practical functions such as heat insulation, sound insulation, etc., and when a user is located inside the vehicle, the material of the inner surface of the roof structure can affect the visual experience of the user, therefore, the aesthetic appearance of the roof structure has an important influence on the user experience.

[0042] The ceiling structure provided in the embodiments of the present application is applied to a vehicle. It should be noted that the vehicle in the present application can refer to a large car, a small car, a special car and the like. For example, according to the vehicle type, the car in the present application can be a sedan type, a SUV type, a Multi-Purpose Vehicles (MPV) type or other types. For the vehicle, a wheel, a power source and a transmission system arranged between the wheel and the power source are generally provided. The transmission system can transmit the power provided by the power source to the wheel to drive the wheel to rotate, thereby driving the vehicle to travel.

[0043] It should be noted that the type of the power source of the vehicle is not limited in the embodiments of the present application. For example, for a fuel vehicle, the power source can refer to a gasoline engine, a diesel engine or the like. For an electric vehicle, the power source can refer to an electric motor. For a hybrid vehicle, the power source can refer to an engine or an electric motor. For a vehicle powered in other ways, the power source can refer to a power generation device.

[0044] The ceiling structure is generally provided with a functional module, such as an audio module (microphone), a loudspeaker, a fragrance box and the like. The present application takes the audio module as an example for description. The audio module is usually located above the user (driver and passenger), which can facilitate the pickup of the user's voice to realize the human-computer interaction between the user and the vehicle.

[0045] In the related art, the ceiling skin material is divided into imitation suede and knitted fabric. When the ceiling skin material is imitation suede, a hole needs to be punched on the surface of the ceiling to realize sound transmission. When the ceiling skin material is knitted fabric, a cover plate needs to be assembled on the surface of the ceiling to realize sound transmission. The overall appearance of the ceiling structure is not good, which affects the riding experience.

[0046] The ceiling structure provided in the embodiments of the present application can realize sound transmission through the decorative layer, so that the sound can pass through the decorative layer and reach the audio module, thereby the audio module can pick up the voice of the user in the vehicle to facilitate the human-computer interaction between the user and the vehicle. In addition, the decorative layer can shield the mounting hole on the audio module and the substrate, so that the surface of the ceiling structure in the user's view is not provided with a sound transmission hole or a cover plate for sound transmission. The inner surface of the ceiling structure is an integral structure, which has good flatness, neatness and appearance, and is also beneficial to improve the user experience.

[0047] On this basis, with reference to Figures 1 to 5 The present application provides a ceiling structure 100, which comprises a substrate 110, an audio module 120, a mounting bracket 130 and a decorative layer 140.

[0048] The substrate 110 includes opposite first and second surfaces 110a and 110b along a thickness direction X of the substrate 110. The substrate 110 is provided with a mounting opening 110c that penetrates the first and second surfaces 110a and 110b. It should be noted that the second surface 110b can be a surface facing the interior space of the vehicle. In other words, the second surface 110b is located below the first surface 110a.

[0049] The audio module 120 can be disposed on the first surface 110a, and a functional part 121 of the audio module 120 is located in the mounting opening 110c. A mounting bracket 130 is disposed on the first surface 110a. The audio module 120 is fixed to the mounting opening 110c by the mounting bracket 130. A decorative layer 140 is located on the second surface 110b of the substrate 110. The decorative layer 140 covers the mounting opening 110c to cover the audio module 120, and the decorative layer 140 allows sound to pass through and reach the audio module 120.

[0050] In the embodiments of the present application, since the decorative layer 140 allows sound to pass through and reach the audio module 120, the decorative layer 140 can realize the sound pickup function of the audio module 120 to the in-vehicle environment. Moreover, since the decorative layer 140 can cover the mounting opening 110c and the audio module 120, the decorative layer 140 is not provided with a sound transmission hole in the area corresponding to the audio module 120, nor is it provided with a cover plate for sound transmission. Therefore, the decorative layer 140 can be a complete surface without a splicing structure or a hole. The surface of the decorative layer 140 is neat and flat in visual effect, has good aesthetics, is conducive to improving the visual effect of the user, and improves the user experience.

[0051] In the embodiments of the present application, the functional part 121 of the audio module 120 is located in the mounting opening 110c, and the functional part 121 of the audio module 120 can face the interior space of the vehicle to improve the stability of the audio module 120 in picking up the sound of the user, thereby improving the reliability of the human-machine interaction between the user and the vehicle.

[0052] It should be noted that the mounting bracket 130 can be used to fix the audio module 120 to the substrate 110 to maintain the stability of the audio module 120 and reduce the possibility that the audio module 120 is detached from the ceiling substrate 110 and shakes during the driving of the vehicle, thereby affecting the sound pickup effect.

[0053] In some examples, the number of audio modules 120 can be multiple. The multiple audio modules 120 can be distributed at different positions of the substrate 110 to pick up the sound of the user at different positions in the vehicle.

[0054] In the embodiments of the present application, the position of the audio module 120 is not limited. For example, the audio module 120 can be set according to the layout of the seats in the vehicle to correspond to the user on the seat.

[0055] In some examples, when the audio module 120 is a microphone, the functional part 121 can be a sound pickup hole of the microphone.

[0056] Exemplarily, the audio module 120 can be a noise reduction microphone. The audio module 120 can pick up low-frequency noise in the vehicle interior and deliver it to an active noise reduction system for processing. The active noise reduction system can cause the audio module 120 to emit an opposite noise to cancel out the noise, achieving noise reduction in the vehicle interior.

[0057] In some embodiments of the present application, the decorative layer 140 can include a knitted layer and an open-cell foam layer. The open-cell foam layer is connected to the second surface 110b of the substrate 110. The knitted layer is located on the side of the open-cell foam layer away from the second surface 110b.

[0058] In embodiments of the present application, the open-cell foam layer has internal pores. The sound in the interior space of the vehicle can be transmitted to the functional part 121 of the audio module 120 through the internal pores, so that the audio module 120 can directly pick up the sound of the user in the interior space of the vehicle.

[0059] In addition, the open-cell foam layer has softness. When the vehicle collides, the user's head contacts the ceiling structure 100, and the softness of the open-cell foam layer can buffer the impact force of the ceiling structure 100 on the user's head, thereby reducing the possibility of injury to the user.

[0060] It should be noted that the knitted layer is located below the open-cell foam layer. The knitted layer faces the interior space of the vehicle and is close to the user. The knitted layer can provide a skin-friendly touch and can avoid the user from touching the ceiling structure 100, thereby reducing the possibility of injury to the user. In addition, the knitted layer has wear resistance, which can improve the service life of the vehicle interior.

[0061] In addition, the knitted layer has low density, which can reduce the weight of the ceiling structure 100, thereby promoting the lightweight design of the vehicle and improving the endurance of the electric vehicle. In addition, the thickness of the knitted layer is controllable, which can effectively reduce the occupation of the interior space of the vehicle, thereby improving the utilization rate of the interior space of the vehicle.

[0062] Therefore, it is easy to understand that the decorative layer 140 of the embodiments of the present application includes a knitted layer and an open-cell foam layer, which can have the functions of air permeability, softness, sound absorption and buffering, and can provide a comfortable, stable and beautiful interior space for the user under the function of picking up sound by the audio module 120.

[0063] In some examples, the decorative layer 140 can further include a non-woven fabric material layer. For example, a needle-punched non-woven fabric. In the thickness direction X of the substrate 110, the open-cell foam layer can be located between the knitted layer and the non-woven fabric material layer.

[0064] In the embodiments of the present application, the specific material of the open-cell foam layer is not limited, for example, the open-cell foam layer can be but is not limited to polyurethane (PU).

[0065] Further, in some embodiments of the present application, referring to Figures 2 to 4 The inner wall of the mounting port 110c surrounds the outer periphery of the functional part 121. The mounting port 110c is used to guide the sound to the functional part 121.

[0066] In the embodiments of the present application, at least part of the functional part 121 is located in the mounting port 110c. The inner wall of the mounting port 110c can surround the outer periphery of the functional part 121, so that the sound of the user can be gathered at the mounting port 110c after entering the ceiling structure 100 through the decorative layer 140. Under the sound guiding effect of the mounting port 110c, the sound of the user is guided into the functional part 121, thereby improving the sound pickup effect of the audio module 120.

[0067] Specifically, the sound can surround the outer periphery of the functional part 121. The inner wall of the mounting port 110c can form a sound guiding cylinder structure to gather and deliver the sound to the functional part 121.

[0068] It should be noted that the shape of the mounting port 110c is not limited in the embodiments of the present application. For example, the shape of the mounting port 110c can be square, circular, etc.

[0069] On this basis, referring to Figure 2 In some embodiments of the present application, the mounting bracket 130 includes a mounting table 131. The mounting table 131 is provided with an opening 131a through which the functional part 121 can pass. The opening 131a is in communication with the mounting port 110c. The mounting table 131 is sealingly connected with the audio module 120.

[0070] In the embodiments of the present application, the mounting table 131 can be used to support the audio module 120. The functional part 121 of the audio module 120 can pass through the opening 131a, so that at least part of the functional part 121 can be located in the mounting port 110c of the substrate 110, so that the functional part 121 can be close to or attached to the decorative layer 140 to facilitate the pickup of the sound of the user in the vehicle.

[0071] The sealing connection between the mounting table 131 and the audio module 120 can make the audio module 120 closely attached to the mounting table 131, so as to reduce the noise generated between the substrate 110 and other structures and transmitted to the functional part 121 through the gap between the mounting table 131 and the audio module 120, thereby affecting the pickup of the user's sound by the audio module 120 and reducing the possibility of affecting the sound pickup effect.

[0072] In some examples, the audio module 120 and the mounting bracket 130 can be fixed by but not limited to the clamping method.

[0073] For example, referring to Figure 2 and Figure 5 The audio module 120 can be provided with a buckle 122, and the mounting bracket 130 can be provided with a clamping groove 130a. Through the cooperation of the buckle 122 and the clamping groove 130a, the audio module 120 and the mounting bracket 130 can be fixedly connected.

[0074] Further, referring to Figure 2 and Figure 3 In some embodiments of the present application, a sealing member 150 is arranged between the audio module 120 and the mounting platform 131 along the thickness direction X of the substrate 110. The audio module 120 abuts against the sealing member 150.

[0075] In the embodiments of the present application, the sealing member 150 can be used to realize the sealed connection between the audio module 120 and the mounting platform 131, so that the noise generated between the substrate 110 and other structures is not easily transmitted to the functional part 121 through the gap between the mounting platform 131 and the audio module 120, which is beneficial to reduce the noise influence on the pickup effect of the functional part 121.

[0076] Specifically, the lower surface of the sealing member 150 can be attached to the mounting platform 131 along the thickness direction X of the substrate 110. The upper surface of the sealing member 150 can be attached to the audio module 120.

[0077] In some examples, the shape of the sealing member 150 can match the shape of the mounting port 110c. When the audio module 120 is fixed to the mounting bracket 130, the sealing member 150 can be located at the outer periphery of the functional part 121 to block the transmission of external noise to the functional part 121.

[0078] In some examples, the mounting platform 131 can be provided with a mounting groove 131b for mounting the sealing member 150. Part of the sealing member 150 can be located in the mounting groove 131b. The mounting groove 131b can limit the sealing member 150, so that the sealing member 150 is not easily displaced, so that the sealing member 150 can be arranged around the outer periphery of the functional part 121.

[0079] It should be noted that the specific material of the sealing member 150 is not limited in the embodiments of the present application, as long as it can realize the blocking effect of noise. For example, the sealing member 150 can be but not limited to a kind of sealing foam.

[0080] Further, referring to Figure 2 In some embodiments of the present application, the audio module 120 and the sealing member 150 are interference-fitted along the thickness direction X of the substrate 110. The interference amount of the audio module 120 and the sealing member 150 is greater than or equal to 0.2mm.

[0081] In the embodiments of the present application, the sealing member 150 can be compressed between the audio module 120 and the mounting table 131 through the interference fit of the audio module 120 and the sealing member 150, which is conducive to improving the sealing between the audio module 120 and the mounting table 131.

[0082] Since the sealing member 150 has a certain elasticity, when the interference amount of the audio module 120 and the sealing member 150 is less than 0.2 mm, the phenomenon that the sealing member 150 is entirely located in the mounting groove 131b is likely to occur, which leads to the failure of the sealing member 150 and the possibility of a gap between the audio module 120 and the mounting table 131. Therefore, by setting the interference amount of the audio module 120 and the sealing member 150 to be greater than or equal to 0.2 mm, the audio module 120 and the sealing member 150 can have a certain interference amount when the audio module 120 is compressed with the mounting table 131, thereby effectively solving the above technical problems.

[0083] It is easy to understand that the greater the interference amount of the audio module 120 and the sealing member 150, the better the sealing effect between the audio module 120 and the mounting table 131 when the audio module 120 is clamped to the mounting bracket 130.

[0084] Further, with reference to Figure 2 and Figure 3 In some embodiments of the present application, the first surface 110a of the substrate 110 is provided with a mounting recess 110d. At least part of the mounting bracket 130 is located in the mounting recess 110d. The mounting bracket 130 is sealingly connected with the inner wall of the mounting recess 110d.

[0085] In the embodiments of the present application, at least part of the mounting bracket 130 can be located in the mounting recess 110d, and part of the outer wall of the mounting bracket 130 can be attached to the inner wall of the mounting recess 110d. The mounting recess 110d can provide a preliminary limiting effect for the mounting bracket 130.

[0086] The sealing connection between the mounting bracket 130 and the inner wall of the mounting recess 110d can achieve the fixed connection of the mounting bracket 130 and the substrate 110. The relative movement between the mounting bracket 130 and the substrate 110 is not easy to occur, so as to ensure the stability of the audio module 120.

[0087] In addition, it is easy to understand that the fixed connection between the mounting bracket 130 and the substrate 110 can make the mounting bracket 130 not easy to shake relative to the substrate 110 during vehicle driving, thereby reducing the possibility of abnormal sound caused by the relative movement between the mounting bracket 130 and the substrate 110, and further reducing the possibility that the abnormal sound affects the pickup effect of the functional part 121.

[0088] In some examples, the sealing connection between the mounting bracket 130 and the inner wall of the mounting recess 110d can be, but is not limited to, glueing. The outer wall of the mounting bracket 130 and the inner wall of the mounting recess 110d can be fixed and sealed by the sealing glue.

[0089] Further, referring to Figure 2 In some embodiments of the present application, the functional part 121 and the decorative layer 140 abut along the thickness direction X of the substrate 110.

[0090] In the embodiments of the present application, the functional part 121 and the decorative layer 140 abut, so the functional part 121 and the decorative layer 140 can be attached to each other. In other words, there is no gap between the functional part 121 and the decorative layer 140 along the thickness direction X of the substrate 110, so the possibility of the sound at the mounting opening 110c reciprocally rebounding in the gap between the functional part 121 and the decorative layer 140 and causing interference with the sound pickup of the audio module 120 can be reduced.

[0091] In some examples, the surfaces of the functional part 121 and the decorative layer 140 opposite to each other along the thickness direction X of the substrate 110 can be attached to each other.

[0092] Further, in some embodiments of the present application, the functional part 121 and the decorative layer 140 are interference-fitted. The interference amount between the functional part 121 and the decorative layer 140 is greater than or equal to 0 and less than or equal to 0.2 mm.

[0093] In the embodiments of the present application, by interference-fitting between the functional part 121 and the decorative layer 140, the sealing effect between the functional part 121 and the decorative layer 140 can be improved, and the possibility of a gap along the thickness direction X of the substrate 110 between the functional part 121 and the decorative layer 140 and causing the sound to rebound in the gap and thus affecting the sound pickup effect can be reduced.

[0094] When the functional part 121 and the decorative layer 140 are interference-fitted, since the decorative layer 140 has elasticity and buffering effect, by setting the interference amount between the functional part 121 and the decorative layer 140 to be less than or equal to 0.2 mm, the functional part 121 is not easy to protrude from the surface of the decorative layer 140 facing the vehicle interior space, so the flatness of the decorative layer 140 is not affected.

[0095] The embodiments of the present application can also provide a vehicle. The vehicle can include a vehicle body and the roof structure 100 in any of the above embodiments.

[0096] In the embodiment of the present application, the roof structure 100 is provided with an audio module 120. The audio module 120 can realize the sound pickup effect of the user's voice, and the decorative layer 140 of the roof structure 100 can not be provided with a sound transmission hole or a sound transmission cover plate structure. The decorative layer 140 can have a neat appearance to improve the user experience.

[0097] In some tests, the audio module 120 in the uninstalled state and the audio module 120 on the roof structure 100 of the embodiment of the present application are tested. The test results show that when the sound corresponding frequency is within 7KHz, the change value of the frequency response curve of the audio module 120 of the roof structure 100 of the embodiment of the present application is very small compared with the audio module 120 in the uninstalled state, or even basically the same. Therefore, the roof structure 100 of the embodiment of the present application has a good appearance, and the sound pickup effect can not be affected by the decorative layer 140.
