[0037] In the description of the embodiments of this application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity, specific order, or primary-secondary relationship of the indicated technical features.

[0038] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0039] It should be noted that in this application, "at least two" includes two and more than two. "Multiple" includes two and more than two.

[0040] An embodiment of this application provides an automobile, which includes a vehicle body and a cover assembly in any one of the embodiments of this application. The cover assembly is disposed in the vehicle body, and the defrosting and defogging openings are used to blow airflows to the side windshield.

[0041] An automobile is a non-railborne vehicle powered by a driving force and having four or more wheels, mainly used for carrying passengers and / or goods. It usually has an enclosed cockpit and at least two seats.

[0042] The power source of the automobile in this application is not limited. Exemplarily, the power source includes but is not limited to gasoline, diesel, power batteries, and / or other energy sources, etc. That is to say, the automobile can be an oil vehicle or a new energy electric vehicle.

[0043] The vehicle body is disposed on the wheels. The vehicle body has a cockpit, which is a space for the driver and passengers to ride. The cockpit includes seats, instrument panels, steering wheels, and other control devices.

[0044] The side windshield refers to the glass on the left and right sides at the front end of the vehicle body, and the side windshield is used to provide lateral vision and lighting. The cover assembly can be close to the interior trim panel area of the A-pillar of the vehicle body.

[0045] The defrosting and defogging openings are used to blow airflows to the side windshield of the automobile to provide defrosting and defogging functions. Frost and fog are the forms presented by the condensation of water in the air on the side windshield.

[0046] It can be understood that the front is the direction in which the vehicle travels forward during driving, the rear is opposite to the front, and the front-rear direction and the left-right direction are perpendicular to each other.

[0047] In the case of a large temperature difference and high humidity inside and outside the vehicle, the side windshield is prone to fogging and / or frosting. If not cleared in time, it will affect the driver's vision and easily cause traffic accidents.

[0048] Please refer to Figures 1 to 6 , an embodiment of the present application provides a cover assembly for an automobile. The cover assembly includes a cover 2 and a speaker 6. The cover 2 includes a defrosting and defogging area 22 and a sound transmission area 21. The defrosting and defogging area 22 forms a defrosting and defogging opening, and the sound transmission area 21 forms a plurality of sound outlet openings 25. The speaker 6 is disposed on the first side of the sound transmission area 21 along the thickness direction of the cover 2.

[0049] It should be noted that unless otherwise specified, the thickness direction in the embodiments of the present application refers to the thickness direction of the cover 2.

[0050] The first side and the second side in the thickness direction of the cover 2 are opposite sides. When the cover assembly is assembled to the vehicle body, the first side in the thickness direction refers to the inner side of the cover 2, and the second side in the thickness direction refers to the outer side of the cover 2.

[0051] The defrosting and defogging opening penetrates through both side surfaces of the cover 2 along the thickness direction, that is to say, air flow can pass through the defrosting and defogging opening and blow to the outer side of the cover 2.

[0052] The sound outlet opening 25 penetrates through both side surfaces of the cover 2 along the thickness direction, that is to say, sound waves can pass through the sound outlet opening 25 and propagate to the outer side of the cover 2.

[0053] The cover assembly provided by the embodiment of the present application divides the cover 2 into a defrosting and defogging area 22 and a sound transmission area 21 in appearance. The defrosting and defogging area 22 forms a defrosting and defogging opening, and the sound transmission area 21 forms a plurality of sound outlet openings 25. The defrosting and defogging opening can provide defrosting and defogging functions, thereby reducing the risk of the side windshield being fogged and frosted and affecting the vision. The sound outlet opening 25 is used to transmit the sound waves of the speaker 6. Integrating the defrosting and defogging opening and the sound outlet opening 25 on the cover 2 can not only provide an installation position for the speaker 6 to meet the installation requirements of the speaker 6, but also provide a defrosting and defogging function. In this way, the defrosting and defogging function and the function of the speaker 6 are integrated into the cover 2, improving the user experience.

[0054] In the related art, the instrument panel uses dense holes for blowing air, and the dense holes are basically located in the middle position of the instrument panel along the left-right direction. The effective ventilation area is small, and only the conventional ventilation function can be realized, and key functions such as rapid defrosting and defogging cannot be realized.

[0055] In some embodiments, please refer to Figure 1, the area of the defrosting and defogging opening is much larger than the area of the sound outlet 25. Exemplarily, the area of the defrosting and defogging opening is five times or more the area of the sound outlet 25.

[0056] The number of the sound outlets 25 can be ten or more, and the porosity of the sound transmission area 21 reaches 50% or more, so as to meet the high porosity requirement of 50% required for high-quality sound effects.

[0057] In some embodiments, please refer to Figure 1 , the cover plate assembly includes an instrument panel 1, and at least one end of the instrument panel 1 in the left-right direction is provided with a cover plate 2.

[0058] The instrument panel 1 is an assembly in the cab for installing various indicating instruments, ignition switches, etc. The instrument panel 1 can not only reflect the operating state of the internal machines of the vehicle, but also is the control center of some devices and the object to be decorated, and is one of the representatives of the overall vehicle style.

[0059] At least one end of the instrument panel 1 in the left-right direction is provided with a cover plate 2, which means that the number of the cover plates 2 can be one or two. Exemplarily, the cover plate 2 can be provided on the left side of the instrument panel 1, or the cover plate 2 can be provided on the right side of the instrument panel 1, or the cover plates 2 can be provided on both the left and right sides of the instrument panel 1.

[0060] In this embodiment, at least one end of the instrument panel 1 in the left-right direction is provided with a cover plate 2, then at least one end of the instrument panel 1 in the left-right direction is provided with a speaker 6 and a defrosting and defogging opening. If speakers 6 and defrosting and defogging openings are provided at both ends of the instrument panel 1 in the left-right direction, defrosting and defogging functions can be provided for the side windshield glasses on both sides, and sound waves can be provided at multiple positions to improve the sound quality.

[0061] In some embodiments, the instrument panel 1 is formed with an avoidance notch, and the cover plate 2 covers the avoidance notch.

[0062] Specifically, the side surface of the second side of the cover plate 2 in the thickness direction is the appearance surface, that is to say, people can view the surface of the second side of the cover plate 2 in the thickness direction.

[0063] In this embodiment, the side surface of the second side of the cover plate 2 in the thickness direction is exposed, which is beneficial to the design of the cover plate 2 and improves the decorative beauty.

[0064] In some embodiments, the cover plate 2 is detachably connected to the instrument panel 1. Exemplarily, the cover plate 2 is snap-connected to the instrument panel 1.

[0065] In some embodiments, please refer to Figure 1 and Figure 3, the cover plate 2 forms a first clamping portion 24, the instrument panel 1 forms a second clamping portion, and the first clamping portion 24 is clamped with the second clamping portion. One of the first clamping portion 24 and the second clamping portion can be a buckle, and the other of the first clamping portion 24 and the second clamping portion can be a tongue.

[0066] In some embodiments, please refer to Figure 2 , the cover plate assembly includes a bracket 4, a speaker 6 is disposed on the bracket 4, and the bracket 4 is detachably connected to the instrument panel 1. The bracket 4 is used to carry the speaker 6, and the speaker 6 is fixed to the instrument panel 1 through the bracket 4. The detachable connection between the bracket 4 and the instrument panel 1 is beneficial to detach the speaker 6 and the bracket 4 according to requirements, facilitating inspection, maintenance and repair.

[0067] The detachable connection includes but is not limited to screw connection, bolt connection and / or clamping, etc.

[0068] In some embodiments, the bracket 4 can also be non-detachably connected to the instrument panel 1. The non-detachable connection includes but is not limited to welding, bonding, etc.

[0069] In some embodiments, please refer to Figure 2 and Figure 3 , one of the bracket 4 and the instrument panel 1 forms a positioning post, and the other of the bracket 4 and the instrument panel 1 forms a positioning groove 45, and at least a part of the positioning post is inserted into the positioning groove 45.

[0070] As an example, in some embodiments, the bracket 4 forms a positioning post, and the instrument panel 1 forms a positioning groove 45. In other embodiments, the instrument panel 1 forms a positioning post, and the bracket 4 forms a positioning groove 45.

[0071] In this embodiment, at least a part of the positioning post is inserted into the positioning groove 45, the positioning post and the positioning groove 45 are inserted and matched, and the positioning post and the positioning groove 45 provide positioning and limiting functions, which is beneficial to the quick positioning and assembly of the bracket 4 and reduces the risk of misassembly.

[0072] In some embodiments, the cover plate assembly includes a first fastener, and the first fastener passes through the bracket 4, the instrument panel 1 and the cover plate 2 to detachably connect the bracket 4, the instrument panel 1 and the cover plate 2.

[0073] As an example, please refer to Figures 2 to 4 , the bracket 4 can form a fastening hole 43, and the first fastener can pass through the fastening hole 43.

[0074] In this embodiment, by passing the first fastener through three parts, the detachable connection of the bracket 4, the instrument panel 1 and the cover plate 2 is realized, which can simplify the assembly process, reduce the usage of the first fastener or other connecting parts, save costs, and can also improve the connection strength and the assembly stability.

[0075] The first fastener can be used to achieve a detachable connection. The first fastener includes, but is not limited to, screws or bolts, etc.

[0076] The number of the first fasteners is not limited. The first fastener can be one or more. A plurality of the first fasteners can be circumferentially and spacedly distributed around the bracket 4.

[0077] In some embodiments, refer to Figures 2 to 6 , the cover plate assembly includes a bracket 4, a speaker 6 is disposed on the bracket 4. The bracket 4 includes a grid plate 41 having grid holes. The grid plate 41 supports the first side of the sound transmission area 21 in the thickness direction. That is to say, the sound transmission area 21 is located on the second side of the grid plate 41 in the thickness direction.

[0078] In this embodiment, the grid plate 41 supports the first side of the sound transmission area 21 in the thickness direction. The grid plate 41 can provide a supporting force for the sound transmission area 21, improve the stress capacity of the sound transmission area 21, and reduce the risk of damage to the sound transmission area 21. The grid holes can reduce the sound wave loss, facilitate the sound wave of the speaker 6 to pass through the grid holes and the sound outlet 25 and propagate outward. In this way, the area and the number of the sound outlets 25 can be relatively increased. That is to say, the porosity of the cover plate 2 is increased, and the sound output quality is improved.

[0079] The connection manner between the speaker 6 and the bracket 4 is not limited. The speaker 6 and the bracket 4 can be detachably connected or non-detachably connected. Exemplarily, the speaker 6 and the bracket 4 can be connected by a second fastener.

[0080] The second fastener can be used to achieve a detachable connection. The second fastener includes, but is not limited to, screws or bolts, etc.

[0081] In some embodiments, refer to Figures 2 to 6 , the speaker 6 forms a positioning hole 62 and an assembly hole 61, the bracket 4 forms a positioning pin 44 and a stud 42. The positioning pin 44 passes through the positioning hole 62. The second fastener can pass through the assembly hole 61 and be in threaded cooperation with the stud 42. With such a design, during the assembly process of the speaker 6 and the bracket 4, the positioning pin 44 can be first inserted into the positioning hole 62 to achieve preliminary positioning, and then the second fastener passes through the assembly hole 61 and is tightened into the threaded hole of the stud 42.

[0082] The number of the positioning holes 62 and the positioning pins 44 is not limited. The number of the positioning holes 62 and the positioning pins 44 is the same. The positioning holes 62 and the positioning pins 44 can both be one or more. A plurality of the positioning pins 44 can be symmetrically distributed on the bracket 4, and a plurality of the positioning holes 62 can be symmetrically distributed on the speaker 6.

[0083] The number of the assembly holes 61 and the studs 42 is not limited, and the number of the assembly holes 61 and the studs 42 is the same. The assembly holes 61 and the studs 42 can each be one or more. A plurality of studs 42 can be symmetrically distributed on the bracket 4, and a plurality of assembly holes 61 can be symmetrically distributed on the speaker 6.

[0084] In some embodiments, referring to Figure 3 , the number of the first fasteners is four, and the number of both the assembly holes 61 and the positioning holes 62 is two. There is one assembly hole 61 and one positioning hole 62 between two of the first fasteners, and there is another assembly hole 61 and another positioning hole 62 between the other two first fasteners.

[0085] In some embodiments, the area of the mesh holes is larger than the area of the sound outlet 25. In this way, the shielding of the sound waves by the mesh plate 41 can be reduced, and the sound transmission loss can be reduced.

[0086] In some embodiments, the bracket 4 includes a frame body. The frame body forms a first opening and a second opening. The first opening and the second opening are opposite and communicate with each other in the thickness direction. The mesh plate 41 covers the first opening, and the diaphragm of the speaker 6 is located in the second opening.

[0087] The diaphragm is a key component of the speaker 6. The diaphragm is an electroacoustic conversion device. The vibration of the diaphragm pushes the air to move to generate sound waves, thereby converting the electrical signal into sound waves.

[0088] As an example, the frame body can be generally in an annular structure with openings on both sides in the thickness direction. The annular structure can be in a circular ring shape, an elliptical ring shape or a polygonal ring shape, etc., which is not limited in this application.

[0089] In this embodiment, the mesh plate 41 is connected to the frame body. The mesh plate 41 covers the first opening, and the diaphragm of the speaker 6 is located in the second opening. The first opening and the second opening are opposite in the thickness direction. The sound waves generated by the diaphragm can propagate from the second opening to the first opening, and then propagate to the outside through the sound outlet 25. There can be a vacant space between the first opening and the second opening. That is to say, there is basically only air between the first opening and the second opening. In this way, the sound wave propagation path is short and the shielding is small, and the sound wave loss can be reduced.

[0090] In some embodiments, with the plane perpendicular to the thickness direction as the projection plane, the projection of the first opening and the projection of the second opening at least partially overlap. That is to say, the projection of the first opening and the projection of the second opening can partially overlap, or the projection of the first opening and the projection of the second opening can completely overlap. Designed in this way, it is beneficial to the propagation of sound waves.

[0091] In some embodiments, with the plane perpendicular to the thickness direction as the projection plane, the projection of the first opening is not less than the projection of the second opening. That is to say, the projection of the first opening is greater than or equal to the projection of the second opening, which is beneficial to the propagation of sound waves.

[0092] In some embodiments, the frame can be detachably connected to the instrument panel 1. As an example, the circumferential direction of the frame can have mounting ears, and the first fastener can pass through the mounting ears, the instrument panel 1, and the cover plate 2. The positioning posts and the studs 42 can be formed on the mounting ears.

[0093] In the related art, for better sound quality, it is required that the porosity of the cover plate be as large as possible, which requires the through-hole size of the cover plate to be as large as possible and the hole pitch to be as small as possible. Due to process limitations, the hole pitch cannot be reduced indefinitely, and usually the through-hole size is increased unilaterally, which will result in poor shielding performance of the cover plate, and internal structures such as speakers are easily seen through from the outside, causing user complaints.

[0094] In some embodiments, referring to Figures 4 to 6 , the cover plate assembly includes a mesh cloth 5, and the mesh cloth 5 is disposed on the first side of the sound transmission area 21 in the thickness direction, and the mesh cloth 5 covers the sound transmission area 21.

[0095] The mesh cloth 5 is a textile structure with multiple holes, usually formed by the interweaving of warp yarns and weft yarns to form multiple holes. In most cases, the multiple holes are evenly distributed.

[0096] In some embodiments, the mesh cloth 5 can cover all the sound outlets 25.

[0097] In this embodiment, the mesh cloth 5 is disposed inside the sound transmission area 21, the mesh cloth 5 covers the sound transmission area 21, and the mesh cloth 5 is a sound transmission structure, which can not only play a role in shielding internal structures such as the speaker 6, but also hardly affect sound transmission. In this way, the area and number of the sound outlets 25 can be increased relatively, that is, the porosity of the cover plate 2 is increased.

[0098] The material of the mesh cloth 5 is not limited. The mesh cloth 5 can be made of natural fibers such as cotton, silk, and linen, and the mesh cloth 5 can also be made of chemical fibers such as nylon, polyester, and spandex. The mesh cloth 5 can be a fabric structure formed by a weaving process.

[0099] In some embodiments, the area of the holes of the mesh cloth 5 is smaller than the area of the sound outlets 25. The mesh cloth 5 has the characteristics of being thin and transparent. The area of the holes of the mesh cloth 5 being smaller than the area of the sound outlets 25 can improve the effect of blocking the line of sight and enhance the aesthetic feeling.

[0100] In some embodiments, the porosity of the mesh cloth 5 can be smaller than the porosity of the sound transmission area 21.

[0101] In some embodiments, referring to Figures 4 to 6 , the cover plate assembly includes a bracket 4. The bracket 4 includes a grid plate 41 with grid holes. The grid plate 41 is located on the first side of the mesh cloth 5 in the thickness direction, and both the grid plate 41 and the sound transmission area 21 are in contact with the mesh cloth 5.

[0102] In this embodiment, the grid plate 41 is located on the first side of the mesh fabric 5 in the thickness direction, and the sound transmission area 21 is located on the second side of the mesh fabric 5 in the thickness direction. The grid plate 41 and the sound transmission area 21 are respectively located on both sides of the mesh fabric 5 in the thickness direction, and both the grid plate 41 and the sound transmission area 21 are in contact with the mesh fabric 5. That is to say, the grid plate 41 and the sound transmission area 21 jointly clamp the mesh fabric 5, and the grid plate 41 can press the mesh fabric 5 against the sound transmission area 21. In this way, the grid plate 41 can not only provide a supporting force for the sound transmission area 21 to strengthen the structural strength of the sound transmission area 21, but also provide support for the mesh fabric 5, so that the mesh fabric 5 is in a compressed state, reducing the vibration of the mesh fabric 5.

[0103] In some embodiments, taking the plane perpendicular to the thickness direction of the cover plate 2 as the projection plane, the projection area of the grid plate 41 is not less than the projection area of the sound transmission area 21. That is to say, the projection area of the grid plate 41 is greater than or equal to the projection area of the sound transmission area 21. In this way, each position of the sound transmission area 21 can basically be supported by the grid plate 41.

[0104] In some embodiments, the porosity of the grid plate 41 is greater than the porosity of the sound transmission area 21. That is to say, the total area of the grid holes of the grid plate 41 can be greater than the total area of the sound outlet 25, improving the sound transmission effect of the grid plate 41.

[0105] In some embodiments, the mesh fabric 5 can cover all the sound outlets 25. The mesh fabric 5 includes a shielding sheet and a wrapping sheet surrounding the circumference of the shielding sheet. The shielding sheet covers the grid plate 41, and the wrapping sheet wraps the outer periphery of the frame body. That is to say, the mesh fabric 5 is generally in the structure of a housing with one end open, and the mesh fabric 5 can be sleeved on the bracket 4. Using the elasticity of the mesh fabric 5, the mesh fabric 5 can be more stably installed on the bracket 4.

[0106] In some embodiments, the mesh fabric 5 can also be fixed to the bracket 4 by means of bonding or the like.

[0107] In some embodiments, please refer to Figures 2 to 6 , the cover plate assembly includes a wind guide shell 3 and a wind guide plate 31. The wind guide shell 3 forms a wind guide channel. The wind guide shell 3 is arranged on the first side of the defrosting and defogging area 22 in the thickness direction, and the wind guide channel is communicated with the defrosting and defogging opening; the wind guide plate 31 is arranged in the wind guide channel.

[0108] As an example, the wind guide plate 31 does not extend into the defrosting and defogging opening.

[0109] In this embodiment, the wind guide channel is used for the flow of air, and the wind guide plate 31 provides a function of guiding the air flow. In this way, the wind guide channel can restrict the air flow, reduce the diffusion of the air flow, which is beneficial to improving the air volume, and the wind guide plate 31 can guide the air flow to a set position.

[0128] In the related art, for better sound quality, it is required that the porosity of the cover plate be as large as possible. This requires that the through-hole size of the cover plate be as large as possible and the hole spacing be as small as possible. However, this places high requirements on the structural strength of the cover plate, and it is difficult for plastic materials to meet the strength requirements. Therefore, the cover plate is basically made of metal material and cannot be made of plastic material. The metal material also has problems of high cost and large weight, and the cost of popularizing the speaker is high.

[0129] In some embodiments, the cover plate 2 is made of plastic. In the embodiments of the present application, structures such as the mesh cloth 5 and the grid plate 41 can provide support for the cover plate 2 and strengthen the structural strength.
