Technical Field

[0001] The present application relates to the field of vehicle manufacturing technology, and in particular to a vehicle sound generating device, a vehicle interactive system, and a vehicle. Background Art

[0002] With the development of intelligent vehicles, there is a demand for human-machine voice interaction outside the vehicle. Related technical centers generally install external speakers on the vehicle's sheet metal or front bumper, and this requires opening holes in the sheet metal or front bumper to facilitate sound transmission and ensure volume. However, this method of installing external speakers in the sheet metal or front bumper is detrimental to the vehicle's aesthetic design and also suffers from poor sealing performance at the opening of the sheet metal or front bumper. Summary of the Invention

[0003] Based on this, it is necessary to provide a vehicle sound device, a vehicle interactive system and a vehicle in view of the fact that the related technology requires opening holes in sheet metal parts or front bumpers to install external speakers, which is not conducive to the aesthetic design of the car's appearance. 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.

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

[0008] The aforementioned vehicle sound-generating device of the present application utilizes a sound-generating unit that passes through a clearance hole and abuts against a trim panel, allowing the sound-generating unit to vibrate the trim panel to produce sound, thereby achieving sound effects such as playing music, emitting prompt sounds, and emitting human voices. Compared to the conventional method of drilling holes in sheet metal to enhance the volume transmission of external speakers, this arrangement avoids the visibility of the aforementioned holes on the vehicle's exterior, and the trim panel can also serve a decorative purpose, thereby enhancing the vehicle's aesthetics. Notably, the sound-generating unit vibrating the trim panel allows users to interact with their voices outside the vehicle without rolling down the window, thus enhancing the user experience. Furthermore, the mounting portion provided on the second mounting side of the mounting plate allows the trim panel to directly face and cover the sheet metal when the mounting plate is mounted on it. This allows for direct sealing between the inner surface of the trim panel and the outer surface of the sheet metal, effectively achieving a fully enclosed seal around the sound-generating unit. This simple and reliable structure effectively improves the sealing performance of the vehicle sound-generating device.

[0009] In one embodiment, the sound unit comprises one or more of an audio actuator, a vibration motor, or piezoelectric ceramics, and the sound unit and the trim panel are bonded together. This connection method is simple and reliable, and can improve the fit between the sound unit and the trim panel.

[0010] In one embodiment, the vehicle sound device includes a connecting piece, the sound unit is fixedly connected to the connecting piece, and the connecting piece is fixedly connected to the second mounting side. Then, the sound unit can be fixed to the mounting plate through the connecting piece, and as long as the setting position of the sound unit relative to the connecting piece is adjusted, the sound unit and the trim panel can be abutted, thereby improving the ease of assembly.

[0011] In one embodiment, the connecting member is configured as a connecting plate member, the connecting plate member is provided with a positioning hole, the connecting plate member is fixedly connected to the second mounting side, and the positioning hole is aligned with the clearance hole, and the sound unit is fixedly clamped in the positioning hole, thereby improving the connection stability between the connecting plate member and the mounting plate.

[0012] In one embodiment, the connecting plate is fixedly connected to the second mounting side by bolts, which can improve assembly convenience. In addition, the bolts can also serve as a mechanism for adjusting the tightness of the abutment between the sound unit and the decorative panel.

[0013] In one embodiment, the area of ​​the decorative panel is larger than the area of ​​the mounting plate, and the decorative panel protrudes relative to the mounting plate at the circumferential edge to form a sealing portion, and the sealing portion is used to seal and fit with the sheet metal part, so that the decorative panel can be easily sealed and the operation difficulty is reduced.

[0014] In one embodiment, the mounting portion is configured as a hook, and the hook is used to be detachably connected to the hook portion of the sheet metal component, which helps to improve the convenience of installing the mounting plate on the sheet metal component.

[0015] In one embodiment, the mounting plate and the decorative plate are integrally formed or bonded to each other, which helps to achieve a stable connection between the mounting plate and the decorative plate.

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

[0017] In one embodiment, the mounting plate is provided with a protrusion on the first mounting side, and the decorative panel abuts against the protrusion so that the decorative panel is spaced apart from the first mounting side. This can improve the vibration effect of the sound unit on the decorative panel, thereby improving the sound emission effect.

[0018] According to the second aspect of the present application, the present application provides a vehicle-use interactive system, including the above-mentioned vehicle-use sound device, the vehicle-use interactive system also includes a vehicle-use system and a controller, the vehicle-use system is used to send signals, the controller is electrically connected to the vehicle-use system, and the controller is used to control the sound unit to vibrate the decorative panel to send sounds according to the signal sent by the vehicle-use system.

[0019] According to a third aspect of the present application, the present application provides a vehicle comprising the above-mentioned vehicle interaction system.

[0020] In one embodiment, the vehicle includes a pillar, the mounting plate of the vehicle sound device is installed on the pillar through the mounting portion, and the decorative panel of the vehicle sound device is sealed and fitted with the sheet metal surface of the pillar, which helps to improve the efficiency of human-computer voice interaction and enhance the protection of the vehicle sound device.

[0032] Considering the existing related technologies, installing external speakers on automobile sheet metal parts requires opening holes in the sheet metal parts to facilitate sound transmission and ensure volume. However, this method of adding external speakers is not conducive to the aesthetic design of the automobile's exterior and also has the problem of poor sealing performance of the sheet metal parts at the opening locations. The present application provides a vehicle-use sound device, vehicle-use interactive system, and vehicle, which can effectively improve the aesthetics of the automobile's exterior and can effectively improve the sealing performance, facilitating application and promotion.

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

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

[0035] It is understandable that in the present application, two B-pillars 11 may be provided, and both B-pillars 11 are provided with the vehicle sound generating device 10 .

[0036] Understandably, most human-vehicle voice interaction occurs on the left and right sides of vehicle 1. Therefore, positioning the vehicle sound device 10 on the B-pillar 11 of vehicle 1 helps improve the efficiency of human-machine voice interaction. Furthermore, positioning the vehicle sound device 10 on the B-pillar 11 of vehicle 1 helps avoid areas of vehicle 1 prone to scratches or accidents, such as door panels, door sills, fender flare guards, and rearview mirrors. This helps optimize the placement of the vehicle sound device 10 and improve its protection.

[0037] It is also worth noting that the above-mentioned traditional technology includes a solution of setting the external speaker in the rearview mirror of the vehicle. Since the exterior rearview mirror is one of the main components for side accident scratches, it has low protection for the external speaker, and this solution has a design pain point of interfering with the installation of the electronic rearview mirror assembly. The present application sets the vehicle sound device 10 at the B-pillar 11 position of the vehicle 1, which can improve the protection of the vehicle sound device 10 and effectively solve the design difficulty of arranging the vehicle sound device 10 of the vehicle 1 at the same time as the electronic rearview mirror assembly.

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

[0039] Please continue to refer to Figure 2 In one embodiment of the present application, a vehicle sound device 10 may include a sound 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 also has a clearance hole 320 through which the sound unit 100 is connected to the trim panel 200. The mounting plate 300 has a mounting portion 310 on the second mounting side 300b. The mounting portion 310 is used to secure to the sheet metal component 20 of the vehicle 1.

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

[0041] Specifically, the above-mentioned vehicle sound device 10 of the present application, through the sound unit 100 passing through the clearance hole 320 and contacting the decorative panel 200, enables the sound unit 100 to emit sound by vibrating the decorative panel 200, thereby achieving sound effects such as playing music, emitting prompt sounds, and emitting human voices. Compared with the method of opening holes in sheet metal parts to enhance the volume propagation of external speakers in traditional technology, such an arrangement avoids the exposure of the aforementioned openings from the appearance of the vehicle 1, and the decorative panel 200 can play a certain decorative role, thereby helping to improve the aesthetics of the appearance of the vehicle 1. It is worth noting that the sound is emitted by the sound unit 100 vibrating the decorative panel 200, so that the user can interact with the human voice outside the vehicle without rolling down the window, which helps to improve the user experience.

[0042] In addition, by providing the mounting portion 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 decorative panel 200 can directly face and cover the sheet metal part 20. In this way, the inner surface of the decorative panel 200 and the outer surface of the sheet metal part 20 can be directly sealed, that is, the sound unit 100 can be fully surrounded and sealed. The structure is simple and reliable, which effectively improves the sealing performance of the vehicle sound device 10.

[0043] Optionally, the above-mentioned sound unit 100 may include one or more of an audio exciter, a vibration motor or piezoelectric ceramics. This helps to ensure the configuration diversity of the sound unit 100 and then be able to adapt to multi-scenario applications. Users can choose one or more of the above-mentioned ones according to actual needs.

[0044] Adaptively, in one embodiment, in the vehicle 1 provided in the above-mentioned embodiment of the present application, the mounting plate 300 of the vehicle sound device 10 can be installed on the pillar of the vehicle 1 through the mounting portion 310, and the trim panel 200 of the vehicle sound device 10 is sealed and fitted with the surface of the sheet metal part 20 of the B-pillar 11.

[0045] Preferably, the mounting plate 300 of the vehicle sound-generating device 10 is mounted to the B-pillar 11 of the upright via the mounting portion 310 , and the trim panel 200 of the vehicle sound-generating device 10 is in sealing contact with the surface of the sheet metal component 20 of the B-pillar 11 . It is worth noting that the mounting plate 300 can be configured in a shape that conforms to the surface of the sheet metal component 20 of the B-pillar 11 . This improves the structural integrity of the mounting plate 300 and the sheet metal component 20 of the B-pillar 11 after installation, thereby contributing to the aesthetics of the vehicle 1 .

[0046] Optionally, see Figure 2 The sheet metal part 20 of the B-pillar 11 may be provided with a mounting position 21 for assembly with the mounting portion 310. Furthermore, the sheet metal part 20 of the B-pillar 11 may be provided with a groove 22 for accommodating the sound unit 100 to prevent the sound 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 that is detachably connected to the hook. This helps to improve the ease of installation of the mounting plate 300 on the sheet metal member 20. Optionally, the aforementioned hook and hook portion can be connected by, but are not limited to, a hook-and-clip connection. Of course, in other embodiments, the mounting portion 310 can also be configured as a structure such as a clip or pin, so as to be fixed to the sheet metal member 20 through a clip-on or pin-on connection.

[0048] It is worth noting that the above-mentioned decorative panel 200 can be, but is not limited to, configured to be sealed with the sheet metal part 20 by sandwiching a sealing strip or applying glue.

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

[0050] Optionally, continue to 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. The sealing portion 210 is used to seal against the sheet metal component 20. In other words, when the mounting plate 300 is fixedly mounted to the sheet metal component 20, the sealing portion 210 forms a gap with the sheet metal component 20 that can be used to sandwich a sealing strip or apply glue. This makes sealing the trim panel 200 easier and reduces the difficulty of operation.

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

[0052] Preferably, continue to refer to Figure 2 The mounting plate 300 is provided with a protrusion 330 on the first mounting side 300a, and the decorative panel 200 abuts against the protrusion 330 and makes the decorative panel 200 and the first mounting side 300a spaced apart, thereby making it possible to form a vibration gap between the decorative panel 200 and the first mounting side 300a of the mounting plate 300, thereby improving the vibration effect of the sound unit 100 on the decorative panel 200, thereby improving the sound emission effect.

[0053] Optionally, combined Figure 2 As shown, the sound 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 unit 100 and the trim panel 200. In addition, by bonding the sound unit 100 and the trim panel 200, the sound 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 device 10 may include a connector 400, the sound unit 100 is fixedly connected to the connector 400, and the connector 400 is fixedly connected to the second mounting side 300b. Then, the sound unit 100 can be fixed to the mounting plate 300 through the connector 400, and as long as the setting position of the sound unit 100 relative to the connector 400 is adjusted, the sound unit 100 can be abutted against the decorative panel 200, thereby improving the ease of assembly.

[0055] Optionally, the connecting member 400 may be, but is not limited to, configured as a plate or a block.

[0056] In some embodiments, continue to refer to Figure 3 The connecting member 400 can be configured as a connecting plate member, which is provided with a positioning hole 410. The connecting plate member is fixedly connected to the second mounting side 300b, and the positioning hole 410 is aligned with the clearance hole 320. The sound unit 100 is fixedly engaged with the positioning hole 410. It is understood that the connecting plate member can be closely attached to the plate surface of the second mounting side 300b of the mounting plate 300, thereby improving the connection stability between the connecting plate member and the mounting plate 300.

[0057] Optionally, the connecting plate can be fixedly connected to the second mounting side 300b by bolts 500, which can improve assembly convenience. In addition, the bolts 500 can also serve as a mechanism for adjusting the tightness of the abutment between the sound unit 100 and the decorative plate 200.

[0058] It should be noted that since the sound unit 100 produces sound by vibrating the decorative panel 200, in the case of long-term vibration, the sound unit 100 and the decorative panel 200 may not fit tightly. At this time, it is only necessary to tighten the bolts 500 to adjust the tightness of the fit between the sound unit 100 and the decorative panel 200.

[0059] It is also worth noting that the connection between the connecting plate and the second mounting side 300b is fixedly connected by bolts 500, thereby achieving a removable connection between the connecting plate and the mounting plate 300. This, in turn, enables the removable installation of the mounting plate 300 with the sound unit 100, thereby improving the ease of assembly and disassembly for maintenance of the sound unit 100. It is understood that the mounting plate 300 can be provided with threaded holes that can be threadedly connected to the aforementioned bolts 500.

[0060] Optionally, the decorative plate 200 may be made of glass, which helps to improve the vibration sound effect between the sound unit 100 and the decorative plate 200. The glass may be made of inorganic glass or organic glass.

[0061] Examples of inorganic glass include, but are not limited to, soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass. Of these, soda-lime glass is particularly preferred from the perspectives of manufacturing cost and formability. The method for forming the glass sheet is not particularly limited. For example, in the case of inorganic glass, a glass sheet formed by a float process or the like is preferred.

[0062] When the glass sheet is made of inorganic glass, it can be either untempered or tempered. Untempered glass is obtained by shaping molten glass into a sheet and 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 tempered glass.

[0063] When the tempered glass is physically strengthened (e.g., air-cooled tempered glass), the temperature difference between the glass surface and the interior creates a compressive stress layer on the glass surface, thereby strengthening the glass surface. When the 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. Alternatively, ultraviolet or infrared absorbing glass can be used. When the glass is made of organic glass, examples of the organic glass material include transparent resins such as polycarbonate and acrylic resins (e.g., polymethyl methacrylate).

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

[0065] Preferably, the color of the glass is set to white, and the inner surface of the glass can be printed with black ink, so that it can adapt to the black appearance of the B-pillar 11 position of most car models, so that the vibration and sound effects and aesthetics of the vehicle 1 can be taken into account.

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

[0067] According to another aspect of the present application, a vehicle-use interactive system is provided, comprising the aforementioned vehicle-use sound generating device 10. The vehicle-use interactive system further comprises a vehicle-use system and a controller, wherein the vehicle-use system is configured to generate signals, and the controller is electrically connected to the vehicle-use system, and is configured to control the sound generating unit 100 to generate sounds by vibrating the decorative panel 200 according to the signals generated by the vehicle-use system.

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

[0069] Optionally, the vehicle 1 provided in the present application may include the above-mentioned vehicle interaction system.

[0070] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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 above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
