Description

Technical Field

[0001] The present application belongs to the technical field of automobile accessories, and in particular relates to an off-vehicle sound exciter and a vehicle. Background Art

[0002] The exterior sound exciter is a device that realizes the function of making sounds outside the vehicle based on the principle of surface sound generation. Currently, the exterior sound exciter is installed on the front and rear B-sides of the vehicle body, and the exterior sound exciter is in direct contact with the exterior environment. Therefore, the exterior sound exciter needs to be fully sealed to achieve a protection level of at least IP67 (Ingress Protection Rating, which defines the protection capability against liquid and solid particles). When the exterior sound exciter is working, the internal voice coil will generate heat, and the sealed structure will make it difficult to discharge the generated heat, which will cause the operating temperature of the exterior sound exciter to be too high, and may even cause the exterior sound exciter to burn out.

DETAILED DESCRIPTION

[0036] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments.

[0038] An exterior sound driver (ESD) is a device that uses the surface acoustic principle to generate sound outside the vehicle. Currently, ESD drivers are installed on the front and rear B-sides of the vehicle body, exposing them to direct contact with the exterior environment. Therefore, they must be fully sealed to achieve a minimum IP67 protection rating. When the ESD driver operates, the internal voice coil generates heat. The sealed structure makes it difficult to dissipate this heat, causing the ESD driver to operate at excessive temperatures and even burn out. Therefore, balancing protection level and heat dissipation is a pressing issue.

[0039] In view of this, an embodiment of the present application provides an off-vehicle sound exciter and a vehicle, which can improve the heat dissipation effect of the off-vehicle sound exciter while ensuring the protection level of the off-vehicle sound exciter.

[0040] In a first aspect, an embodiment of the present application provides an off-vehicle sound exciter. Figure 1 This is an exemplary stereoscopic diagram of an off-vehicle sound exciter provided in an embodiment of the present application. Figure 2 This is an exemplary top view of an off-vehicle sound exciter provided in an embodiment of the present application. Figure 3 yes Figure 2 AA section view in. Figure 4 This is an exemplary exploded diagram of an off-vehicle sound exciter provided in an embodiment of the present application.

[0041] like Figures 1 to 4As shown, the exterior sound exciter of the present application includes a housing 100, within which a sealed cavity is disposed. In some embodiments, the housing 100 can be a split structure, comprising an intermediate housing 30, a first housing 10 disposed on one side of the intermediate housing 30, and a second housing 20 disposed on the other side of the intermediate housing 30. Specifically, the intermediate housing 30 is disposed between the first housing 10 and the second housing 20, and the first housing 10 and the second housing 20 can be fastened to the intermediate housing 30 using snap fasteners.

[0042] In some embodiments, as Figure 4 As shown, a fastener 301 may be provided on the intermediate housing 30, and a hook 302 may be provided on the first housing 10 and the second housing 20. When the first housing 10 and the intermediate housing 30 are assembled, they rotate relative to each other. When the hook 302 hooks onto the fastener 301, the assembly of the first housing 10 and the intermediate housing 30 is complete. When the second housing 20 and the intermediate housing 30 are assembled, they rotate relative to each other. When the hook 302 hooks onto the fastener 301, the assembly of the second housing 20 and the intermediate housing 30 is complete.

[0043] The intermediate shell 30 may be in a hollow cylindrical shape. The first shell 10 covers one end of the intermediate shell 30 , and the second shell 20 covers the other end of the intermediate shell 30 . In this way, the first shell 10 , the second shell 20 and the intermediate shell 30 form a sealed cavity.

[0044] The exterior sound driver also includes a first damper 40 and a second damper 50, both of which are disposed within the sealed cavity formed in the aforementioned embodiment. The first damper 40 is disposed on one side of the intermediate housing 30, and the second damper 50 is disposed on the other side of the intermediate housing 30. The exterior sound driver also includes components disposed within the sealed cavity, such as a magnetic bowl 303, a magnet 304, a magnetic sheet 305, and a voice coil 306. This embodiment does not describe these components in detail.

[0045] like Figure 3 As shown, the first damper 40, the second damper 50, and the components disposed within the sealed cavity separate the sealed cavity into independent first cavity 601, second cavity 602, and third cavity 603. In other words, if no vent holes are provided, the first cavity 601, the second cavity 602, and the third cavity 603 are independent cavities and are not connected to each other.

[0046] It should be noted that a receiving groove can be provided on the shell wall of the first shell 10, and the first damper 40 can be provided in the receiving groove, thereby realizing the connection between the first damper 40 and the first shell 10, and realizing that the first damper 40 separates the cavity of the first shell 10 into two independent cavities. Similarly, a receiving groove is provided on the shell wall of the second shell 20. The second damper 50 is provided in the receiving groove, thereby realizing the connection between the second damper 50 and the second shell 20, and realizing that the second damper 50 separates the cavity of the second shell 20 into two independent cavities. Ultimately, the sealed cavity is separated into the independent first cavity 601, the second cavity 602, and the third cavity 603.

[0047] Figure 5 It is a schematic three-dimensional diagram of the first shell provided in an embodiment of the present application. Figure 6 It is a schematic three-dimensional diagram of the second shell provided in an embodiment of the present application. Figure 7 1 is a schematic top view of a first elastic wave provided in an embodiment of the present application.

[0048] like Figure 5 As shown, the first housing 10 is provided with a first hole group 101, and the first hole group 101 includes at least one through hole. Figure 3 As shown, the first cavity 601 can communicate with the external air through the through holes of the first hole group 101. Figure 6 As shown, the second housing 20 is provided with a second hole group 201, and the second hole group 201 includes at least one through hole. Figure 3 As shown, the second cavity 602 can communicate with the external air through the through holes of the second hole group 201 .

[0049] like Figure 7 As shown, the first damper 40 is provided with a third hole group 401, and the third hole group 401 includes at least one through hole. Figure 3 As shown, the third cavity 603 can be connected to the first cavity 601 through the through holes of the third hole group 401 .

[0050] like Figure 7 As shown, the structure of the second wave damper 50 can be the same as or similar to that of the first wave damper 40. The second wave damper 50 is provided with a fourth hole group 501, and the fourth hole group 501 includes at least one through hole. Figure 3 As shown, the third cavity 603 can be connected to the second cavity 602 through the through holes of the fourth hole group 501 .

[0051] This forms an airflow channel through the first hole group 101, first cavity 601, third hole group 401, third cavity 603, fourth hole group 501, second cavity 602, and second hole group 201. External air can enter the first cavity 601 through the first hole group 101, then flow from the first cavity 601 through the third hole group 401 into the third cavity 603, then from the third cavity 603 through the fourth hole group 501 into the second cavity 602, and finally from the second cavity 602 into the outside through the second hole group 201. This creates an airflow channel that allows external air to enter the interior and internal air to flow out, thereby achieving the effect of dissipating heat from the internal components of the exterior sound actuator.

[0052] It should be noted that external air can also enter the second cavity 602 through the second hole group 201, enter the third cavity 603 from the second cavity 602 through the fourth hole group 501, enter the first cavity 601 from the third cavity 603 through the third hole group 401, and finally flow from the first cavity 601 to the outside through the first hole group 101. Similarly, an air flow channel can be realized in which external air enters the interior and internal air flows out from the interior, thereby achieving the effect of heat dissipation of the internal components of the external sound exciter.

[0053] In some embodiments, an exhaust assembly can also be provided inside the exterior sound exciter, which can guide the airflow. The airflow can be guided according to the flow path in which the external air enters the first cavity 601 through the first hole group 101, enters the third cavity 603 from the first cavity 601 through the third hole group 401, enters the second cavity 602 from the third cavity 603 through the fourth hole group 501, and finally flows from the second cavity 602 through the second hole group 201 into the outside, thereby further improving the heat dissipation effect.

[0054] like Figure 4 As shown, the off-vehicle sound exciter of the embodiment of the present application further includes a first waterproof breathable member 70 and a second waterproof breathable member 80. The first waterproof breathable member 70 is arranged on the side of the first shell 10 facing the second shell 20. The second waterproof breathable member 80 is arranged on the side of the first shell 10 facing the second shell 20. The first waterproof breathable member 70 covers the first hole group 101, and the first waterproof breathable member 70 is configured to restrict non-gaseous substances from passing through the first hole group 101. In other words, the first waterproof breathable member 70 can prevent liquid and solid fixed substances from entering the first cavity 601 through the first hole group 101, thereby achieving a waterproof effect. In addition, the first waterproof breathable member 70 is breathable and can allow gaseous substances to enter the first cavity 601 through the first hole group 101.

[0055] Similarly, the second waterproof breathable member 80 covers the second hole group 201, and the first waterproof breathable member 70 is configured to restrict non-gaseous substances from passing through the second hole group 201. In other words, the first waterproof breathable member 70 prevents liquids and solids from entering the second cavity 602 through the second hole group 201, thereby achieving a waterproof effect. Furthermore, the second waterproof breathable member 80 is breathable, allowing gaseous substances to enter the second cavity 602 through the second hole group 201.

[0056] That is to say, the first waterproof breathable member 70 and the second waterproof breathable member 80 can ensure the smooth flow of the air flow channel of the above embodiment while ensuring the protection level (specifically the waterproof level) of the external vehicle sound exciter, that is, achieve the heat dissipation effect.

[0057] Based on the above embodiment, the vehicle exterior sound exciter of the present application includes an intermediate housing 30, a first housing 10 disposed on one side of the intermediate housing 30, and a second housing 20 disposed on the other side of the intermediate housing 30. The first damper 40 is disposed on one side of the intermediate housing 30. The second damper 50 is disposed on the other side of the intermediate housing 30. The first damper 40, the second damper 50, and the device disposed in the sealed cavity separate the sealed cavity into independent first, second, and third cavities 601, 602, and 603. The first cavity 601 is connected to the outside air through the first hole group 101. The second cavity 602 is connected to the outside air through the second hole group 201. The third cavity 603 is connected to the first cavity 601 through the third hole group 401, and the third cavity 603 is connected to the second cavity 602 through the fourth hole group 501. A first waterproof breathable member 70 is provided on the side of the first housing 10 facing the second housing 20. The first waterproof breathable member 70 covers the first hole group 101 and is configured to restrict non-gaseous substances from passing through the first hole group 101. A second waterproof breathable member 80 is provided on the side of the second housing 20 facing the first housing 10. The second waterproof breathable member 80 covers the second hole group 201 and is configured to restrict non-gaseous substances from passing through the second hole group 201.

[0058] Based on the above structure, airflow channels can be formed in the first hole group 101, the first cavity 601, the third hole group 401, the third cavity 603, the fourth hole group 501, the second cavity 602, and the second hole group 201. In addition, the first waterproof breathable member 70 can achieve a waterproof and breathable effect at the first hole group 101, and the second waterproof breathable member 80 can achieve a waterproof and breathable effect at the second hole group 201. It can be seen that the external vehicle sound exciter provided in the embodiment of the present application can improve the heat dissipation effect of the external vehicle sound exciter while maintaining the protection level of the external vehicle sound exciter.

[0059] In some embodiments, as Figure 5As shown, the first hole group 101 may include a plurality of through holes, thereby improving the air intake effect, and further improving the heat dissipation effect of the off-vehicle sound exciter. The plurality of through holes of the first hole group 101 may be distributed in an array on the first shell 10. Specifically, the plurality of through holes of the first hole group 101 may be distributed in a rectangular array on the first shell 10. The plurality of through holes of the first hole group 101 may also be distributed in a circular array on the first shell 10. This can reduce the difficulty of processing the first hole group 101 on the first shell 10, and due to the increase in the number of through holes on the first shell 10, the air intake volume in the first cavity 601 can be increased, thereby further improving the heat dissipation effect of the off-vehicle sound exciter.

[0060] Figure 8 It is a schematic side view of the first waterproof breathable component provided in an embodiment of the present application. Figure 9 It is a schematic three-dimensional diagram of the first waterproof and breathable component provided in an embodiment of the present application. Figure 9 1 is a schematic top view of a first elastic wave provided in an embodiment of the present application.

[0061] In some embodiments, as Figure 8 and Figure 9 As shown, both the first waterproof breathable member 70 and the second waterproof breathable member 80 may include a waterproof breathable membrane layer 701 and an adhesive layer 702. The waterproof breathable membrane layer 701 and the adhesive layer 702 are stacked and may have the same shape and size. It should be noted that the layered structure of the second waterproof breathable member 80 may be the same as that of the first waterproof breathable member 70, but the arrangement of the fifth hole group of the second waterproof breathable member 80 may differ from the arrangement of the fifth hole group of the first waterproof breathable member 70.

[0062] In some embodiments, the waterproof and breathable membrane layer 701 and the adhesive layer 702 may have different shapes and sizes. Figure 10 As shown, the adhesive layer 702 is only bonded to the edge of the waterproof and breathable membrane layer 701 , so that the waterproof and breathable effect can be achieved without providing a hole group on the adhesive layer 702 .

[0063] like Figure 8 and Figure 9As shown, one side of the adhesive layer 702 is connected to the first shell 10, and the other side of the adhesive layer 702 is connected to the waterproof breathable membrane layer 701. The first waterproof breathable component 70 is arranged on the side of the first shell 10 facing the second shell 20, so one side of the adhesive layer 702 is connected to the side of the first shell 10 facing the second shell 20. The material of the adhesive layer 702 can be a mixture of PC (polycarbonate) + ABS (acrylonitrile-butadiene-styrene copolymer), that is, a thermoplastic plastic made of PC and ABS alloy. It combines the excellent properties of both PC and ABS materials: the formability of ABS material and the mechanical properties, impact strength, temperature resistance, and UV resistance of PC. Application in the first waterproof breathable component 70 can improve the protection level of the vehicle's external sound exciter.

[0064] The adhesive layer 702 can have adhesive surfaces on both sides, so one side (surface) of the adhesive layer 702 can be adhesively connected to the first shell 10, and the other side of the adhesive layer 702 can be adhesively connected to the waterproof and breathable membrane layer 701, thereby realizing the connection between the waterproof and breathable membrane layer 701 and the first shell 10.

[0065] The waterproof and breathable membrane layer 701 is not provided with through holes. The waterproof and breathable membrane layer 701 can be made of a polytetrafluoroethylene microporous material. Polytetrafluoroethylene microporous material has high porosity and uniform pore size distribution, and has advantages such as breathability, low friction coefficient, and extremely low adsorption. It is not only dustproof, but also oleophobic and hydrophobic, as well as thermally stable, resistant to chemical corrosion and UV resistance. It has a wide operating temperature range and can continuously perform its breathable function at -40°C to +150°C. However, the waterproof and breathable membrane layer 701 is not easy to firmly bond to the first shell 10. Therefore, the embodiment of the present application provides an adhesive layer 702, which is first bonded to the waterproof and breathable membrane layer 701, and then bonded to the first shell 10. Compared with directly bonding the waterproof and breathable membrane layer 701 to the first shell 10, the adhesive structure of the present application can improve the firmness of the bonding between the waterproof and breathable membrane layer 701 and the first shell 10, thereby further improving the protection level of the external vehicle sound exciter.

[0066] Continue to see Figure 8 and Figure 9, a fifth hole group 703 is provided on the adhesive layer 702, and the fifth hole group 703 includes at least one through hole; when the first waterproof breathable member 70 is attached to the first shell 10, the fifth hole group 703 of the first waterproof breathable member 70 corresponds to the position of the first hole group 101. The central axis of the through hole in the first hole group 101 may coincide with the central axis of the through hole in the corresponding position of the fifth hole group 703. In other words, the first cavity 601 can be connected to the outside air through at least one through hole in the first hole group 101. When the second waterproof breathable member 80 is attached to the second shell 20, the fifth hole group 703 of the second waterproof breathable member 80 corresponds to the position of the second hole group 201. The central axis of the through hole in the second hole group 201 may coincide with the central axis of the through hole in the corresponding position of the fifth hole group 703 of the second waterproof breathable member 80.

[0067] like Figure 8 and Figure 9 As shown, when the first waterproof breathable member 70 is attached to the first shell 10, the central axis of each through hole in the first hole group 101 coincides with the central axis of the through hole in the corresponding position of the fifth hole group 703. In other words, each through hole in the first hole group 101 is connected to the through hole in the corresponding position of the fifth hole group 703. In other words, each through hole in the first hole group 101 is aligned with the through hole in the corresponding position of the fifth hole group 703, so that the first cavity 601 can communicate with the outside air through each through hole in the first hole group 101, thereby making it easier for the outside air to enter the first cavity 601 from the first hole group 101, thereby improving the heat dissipation effect of the external sound exciter.

[0068] In some embodiments, the through holes of the first hole group 101 are distributed in a rectangular array on the first housing 10, and the through holes of the fifth hole group 703 are distributed in a rectangular array on the adhesive layer 702. Alternatively, the through holes of the first hole group 101 are distributed in a circular array on the first housing 10, and the through holes of the fifth hole group 703 are distributed in a circular array on the adhesive layer 702. This makes it easier to align each through hole of the fifth hole group 703 with the through hole at the corresponding position in the first hole group 101.

[0069] For example, Figure 5 As shown, the through holes of the first hole group 101 are distributed in a rectangular array on the first housing 10. Figure 9 As shown, the through holes of the fifth hole group 703 are arranged in a rectangular array on the adhesive layer 702. When the first waterproof breathable member 70 is attached to the first housing 10, the rectangular array of the first hole group 101 and the rectangular array of the fifth hole group 703 are more easily aligned. The aligned first and fifth hole groups 101 and 703 make it easier for external air to enter the first cavity 601 through the first hole group 101, thereby improving the heat dissipation effect of the external sound exciter.

[0070] It should be noted that, since the first hole group 101 is provided on the first shell 10 , the first hole group 101 may be circular holes. Circular holes have the smallest stress concentration, which can reduce the influence of the circular holes on the strength of the first shell 10 .

[0071] In some embodiments, as Figure 5 As shown, a first attachment groove 102 is provided on the side of the first housing 10 facing the first waterproof breathable member 70. The first waterproof breathable member 70 is disposed within the first attachment groove 102. The depth of the first attachment groove 102 can be greater than the thickness of the first waterproof breathable member 70. Because the first waterproof breathable member 70 is disposed within the first attachment groove 102, the edge of the first waterproof breathable member 70 is less likely to lift when adhered to the first housing 10. This ensures a more secure bond between the first waterproof breathable member 70 and the first housing 10, further enhancing the protection level of the exterior vehicle sound exciter.

[0072] In addition, the outer contour of the first pasting groove 102 is adapted to the outer contour of the first waterproof breathable member 70. Figure 5 As shown, the outer contour of the first attachment groove 102 is rectangular, and the outer contour of the corresponding first waterproof breathable member 70 is also rectangular. If the outer contour of the first attachment groove 102 is circular, the outer contour of the corresponding first waterproof breathable member 70 can also be circular. In other words, the outer contour edge of the first waterproof breathable member 70 contacts the sidewall of the first attachment groove 102. This can not only increase the area of ​​the first waterproof breathable member 70 (thus increasing the number of through holes and improving heat dissipation), but also further strengthen the security of the first waterproof breathable member 70 and the first attachment groove 102 (thus improving the protection level of the external sound exciter).

[0073] like Figure 6 As shown, the second housing 20 may also be provided with a second attachment groove 207, the outer contour of which matches the outer contour of the second waterproof breathable member 80. The outer contour edge of the second waterproof breathable member 80 contacts the sidewall of the second attachment groove 207, thereby enhancing the secure connection between the second waterproof breathable member 80 and the second attachment groove 207 (thereby improving the protection level of the external sound exciter).

[0074] The vehicle external sound exciter is a harmonic generator and a sound processing device that can modify and beautify the sound signal. In some embodiments, such as Figure 4 and Figure 6As shown, the second housing 20 includes a housing body 203, with a connector 204 disposed on the periphery of the housing body 203. Connector 204 is provided within connector 205. The exterior sound exciter further includes a circuit assembly (not shown) mounted within the sealed cavity and electrically connected to the connecting pins 205. The circuit assembly within the housing can be electrically connected to the circuitry outside the housing via the connecting pins 205, thereby enabling the operation of the exterior sound exciter to be controlled by the external circuitry.

[0075] In addition, a welding piece 206 is provided inside the second shell 20, and the welding piece 206 is electrically connected to the internal circuit component. At the same time, the welding piece 206 is electrically connected to the connecting pin 205. After the connecting pin 205 is electrically connected to the external circuit, the internal circuit and the external circuit can be electrically connected.

[0076] In some embodiments, at least one boss 202 is provided on the side of the second housing 20 facing the first housing 10, and the through holes of the second hole group 201 pass through the boss 202. In other words, the through holes of the second hole group 201 are provided on the boss 202. Since the first hole group 101 has more through holes, the first hole group 101 is directly provided on the first housing 10. Figure 6 As shown, there is only one through hole in the second hole group 201. The boss 202 is provided on the second shell 20, and then the through hole is provided on the boss 202, which can avoid directly drilling a hole on the second shell 20 and affecting the strength of the second shell 20.

[0077] Furthermore, by providing a boss 202 on the second housing 20 and then providing a second hole set 201 on the boss 202, the difficulty of mold processing for the second housing 20 can be reduced. Reinforcing ribs are also provided on the second housing 20 to enhance its overall strength, thereby further improving the protection level of the exterior sound exciter.

[0078] A mounting groove can be provided on the boss 202. The second waterproof breathable member 80 has a similar structure to the first waterproof breathable member 70, comprising an adhesive layer and a waterproof breathable membrane layer. One side of the adhesive layer is bonded to the bottom of the mounting groove, while the other side of the adhesive layer is bonded to the waterproof breathable membrane layer, thereby connecting the second waterproof breathable member 80 to the second housing 20. Furthermore, the through-holes provided in the adhesive layer align with the through-holes of the second hole group 201, thereby allowing air in the second cavity 602 to flow from the second hole group 201 to the outside. This structure also achieves a waterproof and breathable effect on the second housing 20.

[0079] It should be noted that, in order to further improve the air intake and exhaust effects inside the vehicle exterior sound exciter, the second hole group 201 of the second shell 20 can also be arranged according to the first hole group 101. However, in order to ensure the strength of the second shell 20, it is preferred to follow Figure 6 As shown, the second hole group 201 is arranged.

[0080] In some embodiments, as Figure 3 As shown, along the central axis of the shell, the projection of the first hole group 101 does not overlap with the projection of the second hole group 201. That is to say, in the overall structure of the external sound exciter, the first hole group 101 and the second hole group 201 are staggered. By staggering the first hole group 101 of the first shell 10 and the second hole group 201 of the second shell 20 by a certain distance, a "maze"-like passage is formed between the two. This can increase the difficulty of foreign matter (dust, water vapor) entering the interior of the shell, thereby further improving the protection level of the external sound exciter.

[0081] Furthermore, if the first hole group 101 of the first housing 10 and the second hole group 201 of the second housing 20 are aligned, the continuous straight line formed by the hole edges will become a weak line in the housing structure, making it more susceptible to deformation or fracture under impact or pressure. Therefore, staggering the first hole group 101 of the first housing 10 and the second hole group 201 of the second housing 20 can break this potential weak line, distributing stress over a larger area of ​​the housing, and helping to maintain the rigidity and strength of the overall structure.

[0082] A second aspect of the present application provides a vehicle, which includes a vehicle body and the external sound exciter described in the first aspect. The external sound exciter can improve the heat dissipation effect while ensuring the protection level.
