Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a vehicle sound-generating device, a vehicle interaction system, and a vehicle. Background Technology

[0002] With the development of automotive intelligence, the demand for human-machine voice interaction outside the vehicle has emerged. Related technical centers typically install external speakers on the car's sheet metal or front bumper, requiring openings in these areas to allow sound transmission and ensure sufficient volume. However, this method of installing external speakers by making openings in the sheet metal or front bumper is detrimental to the car's aesthetic design and also results in poor sealing at the opening locations. Summary of the Invention

[0003] Based on this, it is necessary to address the issue that the method of installing external speakers by making openings in sheet metal parts or front bumpers in related technologies is not conducive to the aesthetic design of the car's appearance, and at the same time, there is a problem that the sealing performance of sheet metal parts or front bumpers at the opening positions is poor. Therefore, a vehicle sound device, vehicle interaction system and vehicle should be provided.

[0004] According to a first aspect of this application, this application provides a vehicle-mounted sound-generating device, the vehicle-mounted sound-generating device comprising:

[0005] Sound-generating unit;

[0006] Decorative panels;

[0007] The mounting plate includes a first mounting side and a second mounting side. The trim panel is connected to the first mounting side. The mounting plate also has a clearance hole through which the sound unit passes and connects to the trim panel. The mounting plate has a mounting part on the second mounting side for fixing to the sheet metal parts of the vehicle.

[0008] The aforementioned automotive sound-generating device, through which the sound-generating unit passes through a clearance hole and abuts against the trim panel, allows the sound-generating unit to emit sound by vibrating the trim panel, thereby achieving sound effects such as playing music, issuing alerts, and emitting human voices. Compared to the traditional method of creating openings in the sheet metal to enhance the volume propagation of external speakers, this design avoids the exposure of such openings on the vehicle's exterior, and the trim panel also serves a decorative purpose, thus improving the vehicle's aesthetics. Notably, by using the sound-generating unit to vibrate the trim panel to emit sound, users can interact with each other from outside the vehicle without rolling down the windows, thus enhancing the user experience. Furthermore, the mounting plate's installation on the second mounting side allows the trim panel to directly face and cover the sheet metal when the mounting plate is installed. This allows for direct sealing between the inner surface of the trim panel and the outer surface of the sheet metal, achieving a complete enclosed seal for the sound-generating unit. The structure is simple and reliable, effectively improving the sealing performance of the automotive sound-generating device.

[0009] In one embodiment, the sound-generating unit includes one or more of an audio exciter, a vibration motor, or a piezoelectric ceramic, and the sound-generating unit is bonded to the decorative panel. This connection method is simple and reliable, and can improve the adhesion between the sound-generating unit and the decorative panel. In addition, by bonding the sound-generating unit to the decorative panel, the sound-generating unit and the decorative panel form a structural whole, which facilitates overall assembly and disassembly, and improves the ease of assembly and disassembly.

[0010] In one embodiment, the vehicle sound-generating device includes a connector, the sound-generating unit is fixedly connected to the connector, and the connector is fixedly connected to the second mounting side. The sound-generating unit can then be fixed to the mounting plate via the connector. By simply adjusting the position of the sound-generating unit relative to the connector, the sound-generating unit can be made to abut against the trim panel, thus improving the ease of assembly.

[0011] In one embodiment, the connector is configured as a connecting plate with a positioning hole. The connecting plate is fixedly connected to the second mounting side, and the positioning hole is aligned with the clearance hole. The sound-generating unit is fixedly snapped into the positioning hole, which improves the connection stability between the connecting plate and the mounting plate.

[0012] In one embodiment, the connecting plate is fixedly connected to the second mounting side by bolts, which improves assembly convenience. Additionally, the bolts can also serve as an adjustment mechanism for the tightness of the contact between the sound-generating unit and the trim panel.

[0013] In one embodiment, the area of ​​the trim panel is larger than the area of ​​the mounting plate, and the trim panel protrudes from the mounting plate at its circumferential edge to form a sealing portion, which is used to seal and fit with the sheet metal part. This facilitates the sealing process of the trim panel and reduces the difficulty of operation.

[0014] In one embodiment, the mounting portion is configured as a hook for detachable connection with the hook portion of the sheet metal part, which helps to improve the ease of mounting the mounting plate on the sheet metal part.

[0015] In one embodiment, the mounting plate is integrally formed with or bonded to the trim panel, which helps to achieve a stable connection between the mounting plate and the trim panel.

[0016] In one embodiment, the trim panel is made of glass, which helps to improve the vibration sound generation effect between the sound-generating unit and the trim panel.

[0017] In one embodiment, the mounting plate has a protrusion on the first mounting side, and the decorative panel abuts against the protrusion and is spaced apart from the first mounting side, which can improve the vibration effect of the sound-generating unit on the decorative panel, thereby improving the sound output effect.

[0018] According to a second aspect of this application, this application provides a vehicle interaction system including the aforementioned vehicle sound-emitting device. The vehicle interaction system further includes a vehicle infotainment system and a controller. The vehicle infotainment system is used to emit signals, and the controller is electrically connected to the vehicle infotainment system. The controller is used to control the sound-emitting unit to emit sound by vibrating the trim panel according to the signals emitted by the vehicle infotainment system.

[0019] According to a third aspect of this application, this application provides a vehicle including the aforementioned vehicle interaction system.

[0020] In one embodiment, the vehicle includes a pillar, and the mounting plate of the vehicle sound device is mounted on the pillar via the mounting part. The trim panel of the vehicle sound device is sealed and fitted to the sheet metal surface of the pillar, which helps to improve the efficiency of human-machine voice interaction and enhances the protection of the vehicle sound device.

[0032] In existing technologies, installing external speakers on automotive sheet metal parts requires creating openings in the sheet metal to allow sound to penetrate and ensure sufficient volume. However, this method of installing external speakers is detrimental to the aesthetic design of the vehicle's exterior and also results in poor sealing performance at the opening locations on the sheet metal. This application provides a vehicle sound-generating device, a vehicle interaction system, and a vehicle that can effectively improve the aesthetics of the vehicle's exterior and enhance sealing performance, facilitating application and promotion.

[0033] Please refer to Figure 1 This application provides a vehicle 1, which may include a vehicle sound-generating device 10.

[0034] Optionally, the vehicle-mounted sound-emitting device 10 may, but is not limited to, be installed at a pillar position in the vehicle 1. Optionally, the pillar may, but is not limited to, the A-pillar, B-pillar, C-pillar, or D-pillar of the vehicle. Figure 1As shown, in one embodiment, the vehicle voice-emitting device 10 can be installed at the B-pillar 11. It is worth noting that the vehicle voice-emitting device 10 is used for human-vehicle voice interaction outside the vehicle.

[0035] Understandably, the above-mentioned B-pillar 11 of this application may be provided in two forms, and both B-pillars 11 are provided with the above-mentioned vehicle sound-emitting device 10.

[0036] Understandably, most human-vehicle voice interaction takes place on the left and right sides of vehicle 1. Therefore, placing the vehicle voice device 10 at the B-pillar 11 of vehicle 1 helps improve the efficiency of human-machine voice interaction. In addition, placing the vehicle voice device 10 at the B-pillar 11 of vehicle 1 also helps to avoid areas of vehicle 1 that are prone to scratches or accidents, such as door panels, door sills, wheel arch protectors, and rearview mirrors, thereby optimizing the arrangement of the vehicle voice device 10 and improving its protection.

[0037] It is also worth noting that the aforementioned conventional technologies include a solution that places the external speaker in the vehicle's rearview mirror. Since the rearview mirror is one of the main components involved in side collisions, it offers low protection for the external speaker. Furthermore, this solution suffers from the design flaw of interference with the installation of the electronic rearview mirror assembly. In contrast, this application places the vehicle sound device 10 at the B-pillar 11 of the vehicle 1, which improves the protection of the vehicle sound device 10 and effectively solves the design difficulty of simultaneously arranging the vehicle sound device 10 with the electronic rearview mirror assembly.

[0038] This application also makes the following improvements to the vehicle sound-generating device 10.

[0039] Please continue to refer to this. Figure 2 In one embodiment of this application, a vehicle sound-generating device 10 may include a sound-generating unit 100, a trim panel 200, and a mounting plate 300. The mounting plate 300 may include a first mounting side 300a and a second mounting side 300b. The trim panel 200 is connected to the first mounting side 300a. The mounting plate 300 is also provided with a clearance hole 320 through which the sound-generating unit 100 passes and is connected to the trim panel 200. The mounting plate 300 is provided with a mounting portion 310 on the second mounting side 300b, which is used to fix to the sheet metal part 20 of the vehicle 1.

[0040] It should be noted that the aforementioned first mounting side 300a and second mounting side 300b are respectively the plate surfaces located on opposite sides of the mounting plate 300. It should also be noted that the vehicle sound-generating device 10 described in this application can generate sound by vibrating the plate through the sound-generating unit 100. This technology is conventional in the field, and its sound-generating principle will not be elaborated here. What is noteworthy is the technical effect achieved by the arrangement of the sound-generating unit 100 and the trim panel 200 on the vehicle body, which balances the aesthetic appeal of the vehicle's appearance with improved sealing performance.

[0041] Specifically, the vehicle sound-generating device 10 described in this application uses a sound-generating unit 100 that passes through a clearance hole 320 and abuts against a trim panel 200. This allows the sound-generating unit 100 to emit sound by vibrating the trim panel 200, thereby achieving sound effects such as playing music, issuing alerts, and emitting human voices. Compared to the traditional method of opening holes in sheet metal parts to enhance the volume propagation of external speakers, this design avoids the exposure of such openings on the exterior of the vehicle 1, and the trim panel 200 also serves a decorative purpose, thus contributing to improving the aesthetics of the vehicle 1. Notably, by emitting sound through the vibration of the trim panel 200 by the sound-generating unit 100, users can interact with each other from outside the vehicle without rolling down the windows, thus enhancing the user experience.

[0042] In addition, by providing a mounting part 310 on the second mounting side 300b of the mounting plate 300, when the mounting plate 300 is installed on the sheet metal part 20, the trim panel 200 can directly face and cover the sheet metal part 20. In this way, the inner surface of the trim panel 200 and the outer surface of the sheet metal part 20 can be directly sealed, thus achieving a full-enclosed seal of the sound unit 100. The structure is simple and reliable, effectively improving the sealing performance of the vehicle sound device 10.

[0043] Optionally, the sound generating unit 100 may include one or more of an audio exciter, a vibration motor, or a piezoelectric ceramic, which helps to ensure the configuration diversity of the sound generating unit 100 and thus adapt to multiple application scenarios. Users can choose one or more of the above according to their actual needs.

[0044] Adaptively, in one embodiment, in the vehicle 1 provided in the above embodiments of this application, the mounting plate 300 of the vehicle sound device 10 can be mounted on the pillar of the vehicle 1 via the mounting part 310, and the trim panel 200 of the vehicle sound device 10 is sealed and fitted to the surface of the sheet metal part 20 of the B-pillar 11.

[0045] Preferably, the mounting plate 300 of the vehicle sound-emitting device 10 is mounted to the B-pillar 11 in the pillar via the mounting part 310, and the trim panel 200 of the vehicle sound-emitting device 10 is sealed and fitted to the surface of the sheet metal part 20 of the B-pillar 11. It is worth noting that the aforementioned mounting plate 300 can be configured to fit the shape of the sheet metal part 20 of the B-pillar 11, which can improve the structural integrity of the mounting plate 300 and the surface of the sheet metal part 20 of the B-pillar 11 after installation, thereby helping to improve the aesthetics of the vehicle 1.

[0046] Optionally, see Figure 2 The sheet metal part 20 of the aforementioned B-pillar 11 may be provided with a mounting position 21 for assembly with the mounting part 310. In addition, the sheet metal part 20 of the aforementioned B-pillar 11 may also be provided with a groove 22 for accommodating the sound-emitting unit 100 to prevent the sound-emitting unit 100 from colliding with the sheet metal part 20 of the B-pillar 11 during operation.

[0047] Optionally, combined Figure 2 and Figure 3 As shown, the mounting portion 310 can be configured as a hook, and the aforementioned mounting position 21 can be configured as a hook portion detachably connected to the hook, which helps to improve the ease of mounting the mounting plate 300 on the sheet metal part 20. Optionally, the aforementioned hook and hook portion can be connected by a snap-fit ​​method, but are not limited to this. Of course, in some other embodiments, the mounting portion 310 can also be configured as a snap-fit ​​or pin structure to be fixed to the sheet metal part 20 by snap-fit ​​or pin connection.

[0048] It is worth noting that the aforementioned trim panel 200 may be configured to be sealed to the sheet metal part 20 by means of clamping a sealing strip or applying adhesive.

[0049] For example, when the mounting plate 300 is installed on the sheet metal part 20 of the vehicle 1, the edge of the trim plate 200 can be sealed with glue, or a sealing strip can be pre-installed along the edge of the trim plate 200 or at the corresponding position of the sheet metal part 20, so that the trim plate 200 can directly press the sealing strip onto the surface of the sheet metal part 20 to achieve sealing treatment. The operation is simple and convenient and the sealing performance is good.

[0050] Optionally, please continue reading Figure 2 The area of ​​the trim panel 200 is larger than that of the mounting plate 300, and the trim panel 200 protrudes from the mounting plate 300 at its circumferential edge to form a sealing portion 210, which is used to seal and fit with the sheet metal part 20. In other words, when the mounting plate 300 is fixedly installed on the sheet metal part 20, the sealing portion 210 can form a gap with the sheet metal part 20 that can be used to clamp a sealing strip or apply adhesive, thus facilitating the sealing treatment of the trim panel 200 and reducing the difficulty of operation.

[0051] Alternatively, the mounting plate 300 can be integrally formed with the trim panel 200 or bonded to each other, which helps to achieve a stable connection between the mounting plate 300 and the trim panel 200.

[0052] Preferably, see below. Figure 2 The mounting plate 300 has a protrusion 330 on the first mounting side 300a. The decorative panel 200 abuts against the protrusion 330 and is spaced apart from the first mounting side 300a, thereby forming a vibration gap between the decorative panel 200 and the first mounting side 300a of the mounting plate 300. This can improve the vibration effect of the sound unit 100 on the decorative panel 200, thereby improving the sound output effect.

[0053] Optionally, combined Figure 2 As shown, the sound-emitting unit 100 can be bonded to the trim panel 200. This connection method is simple and reliable, and can improve the fit between the sound-emitting unit 100 and the trim panel 200. In addition, by bonding the sound-emitting unit 100 to the trim panel 200, the sound-emitting unit 100 and the trim panel 200 form a structural whole, which facilitates overall assembly and disassembly, and improves the ease of assembly and disassembly.

[0054] Of course, in some other embodiments, such as Figure 3 As shown, the vehicle sound-generating device 10 may include a connector 400. The sound-generating unit 100 is fixedly connected to the connector 400, and the connector 400 is fixedly connected to the second mounting side 300b. Subsequently, the sound-generating unit 100 can be fixed to the mounting plate 300 through the connector 400. As long as the setting position of the sound-generating unit 100 relative to the connector 400 is adjusted, the sound-generating unit 100 can be made to abut against the trim panel 200, which improves the ease of assembly.

[0055] Optionally, connector 400 may be configured as a plate or a block.

[0056] In some embodiments, continue reading Figure 3 The connector 400 can be configured as a connecting plate, which has a positioning hole 410. The connecting plate is fixedly connected to the second mounting side 300b, and the positioning hole 410 is aligned with the clearance hole 320. The sound-emitting unit 100 is fixedly snapped into the positioning hole 410. Understandably, the connecting plate can fit tightly against the surface of the second mounting side 300b of the mounting plate 300, which can improve the connection stability between the connecting plate and the mounting plate 300.

[0057] Optionally, the aforementioned connecting plate can be fixedly connected to the second mounting side 300b by bolts 500, which improves assembly convenience. In addition, bolts 500 can also serve as an adjustment mechanism for the tightness of the contact between the sound-generating unit 100 and the trim panel 200.

[0058] It should be noted that since the sound-generating unit 100 generates sound by vibrating the trim panel 200, under long-term vibration, the sound-generating unit 100 and the trim panel 200 may not fit tightly together. In this case, simply tightening the bolt 500 will adjust the tightness of the fit between the sound-generating unit 100 and the trim panel 200.

[0059] It is also worth noting that by fixing the connecting plate to the second mounting side 300b with bolts 500, a detachable connection between the connecting plate and the mounting plate 300 is achieved. This allows for the detachable mounting plate 300 with the sound-generating unit 100, thereby improving the ease of disassembly and assembly for maintenance of the sound-generating unit 100. Understandably, the mounting plate 300 may be provided with threaded holes that can be screwed into corresponding bolts 500.

[0060] Alternatively, the trim panel 200 can be made of glass, which helps to improve the vibration and sound generation effect between the sound-generating unit 100 and the trim panel 200. The glass can be made of inorganic glass or organic glass.

[0061] As inorganic glass, various types can be used, including but not limited to soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass. Among these, soda-lime glass is particularly preferred from the viewpoint of manufacturing cost and formability. The method of forming the glass sheet is not particularly limited. For example, in the case of inorganic glass, glass sheets formed by the float glass process or similar methods are preferred.

[0062] When the glass sheet is inorganic glass, it can be either untempered or tempered. Untempered glass is obtained by molding molten glass into a sheet shape and then slowly cooling it. Tempered glass is obtained by forming a compressive stress layer on the surface of untempered glass; it can be air-cooled tempered glass or chemically strengthened glass.

[0063] When tempered glass is physically strengthened (e.g., air-cooled tempered glass), a compressive stress layer is generated on the glass surface due to the temperature difference between the glass surface and the interior, thereby strengthening the glass surface. When tempered glass is chemically strengthened, compressive stress can be generated on the glass surface after bending using methods such as ion exchange to strengthen the glass surface. Additionally, glass that absorbs ultraviolet or infrared radiation can be used. When the glass is made of acrylic glass, examples of materials for acrylic glass include transparent resins such as polycarbonate and acrylic resins (e.g., polymethyl methacrylate).

[0064] Furthermore, the thickness of the aforementioned trim panel 200 can be, but is not limited to, 1.0mm-5mm. For example, the thickness of the aforementioned trim panel 200 can be set to 1.0mm, 2.0mm, 3.0mm, 4.0mm, or 5.0mm, etc.

[0065] Preferably, the glass is set to white, and the inner surface of the glass can be printed with black ink, so as to adapt to the black appearance of most models with B-pillar 11, thus balancing the vibration and sound generation effect of vehicle 1 and aesthetics.

[0066] Of course, in other embodiments, the decorative panel 200 can also be made of plastic or metal materials, such as plastic panels made of PC (Polycarbonate) or PMMA (Polymethyl Methacrylate), or metal panels made of aluminum, stainless steel, etc.

[0067] According to another aspect of this application, this application also provides a vehicle interaction system, including the aforementioned vehicle sound-emitting device 10. The vehicle interaction system further includes a vehicle infotainment system and a controller. The vehicle infotainment system is used to emit signals, and the controller is electrically connected to the vehicle infotainment system. The controller is used to control the sound-emitting unit 100 to emit sound through the vibrating trim panel 200 according to the signals emitted by the vehicle infotainment system.

[0068] Understandably, the sound-emitting unit 100 of this application can be electrically connected to the vehicle infotainment system and controller via a wiring harness, but is not limited to that provided. Optionally, the sound-emitting unit 100 of this application may also be provided with a wireless receiving module for wirelessly receiving signals, which helps to simplify the connection wiring.

[0069] Optionally, the vehicle 1 provided in this application may include the aforementioned vehicle interaction system.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
