[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figures 1-3 The present invention describes a sound alert device 1 for a vehicle, which can be installed on a vehicle.

[0021] According to the first aspect of the present invention, a sound reminder device 1 for a vehicle, such as Figures 1-3As shown, the sound alert device 1 for a vehicle may include: an air filter 10, a muffler 20, and a warning sound simulation device 30. The warning sound simulation device 30 is connected to the muffler 20, and the warning sound simulation device 30 has a first state. When the warning sound simulation device 30 is in the first state, it is connected to the air filter 10. The warning sound simulation device 30 is configured to emit a sound when driven by the gas flowing in from the air filter 10 in the first state, so that the sound flows into the muffler 20. The muffler 20 is configured to cancel the frequency of the sound so that the sound alert device 1 emits a warning sound.

[0022] It should be noted that the drive motors of existing hybrid vehicles operate with low noise. The warning sounds of hybrid vehicles in pure electric mode have a single audio frequency and poor recognizability, making it difficult for pedestrians to perceive the vehicle's location by sound, which can easily lead to a collision risk between the vehicle and the pedestrian.

[0023] Based on this, this application proposes a sound alert device 1 for a vehicle. A warning sound simulation device 30 can emit a sound. The warning sound simulation device 30 can be connected to a silencer 20, which can eliminate the frequency of the sound emitted by the warning sound simulation device 30, thereby achieving the effect of the sound alert device 1 emitting a warning sound. The warning sound simulation device 30 can have a first state. In the first state, the warning sound simulation device 30 can be connected to an air filter 10. The air filter 10 can filter the air flowing through it, and the filtered air can flow into the warning sound simulation device 30, which helps to improve the purity of the air flowing into the warning sound simulation device 30. When the warning sound simulation device 30 is in the first state, that is, when the warning sound simulation device 30 is connected to the air filter 10, air can flow into the warning sound simulation device 30 after being filtered by the air filter 10. The warning sound simulation device 30 can be driven by the air flowing in from the air filter 10 to emit a sound. When the warning sound simulation device 30 is working, the sound can flow into the silencer 20 along with the air flowing in from the air filter 10. The silencer 20 can eliminate the frequency of the sound generated by the warning sound simulation device 30 so that the sound emitted by the warning sound simulation device 30 can simulate the noise of the engine 53, which is conducive to achieving the effect of the sound reminder device 1 emitting a warning sound that can be noticed by pedestrians.

[0024] In this embodiment of the application, the warning sound simulation device 30 can emit a sound when it is in the first state, which is beneficial to make the sound reminder device 1 emit a warning sound that can be noticed by pedestrians. Pedestrians around the vehicle can perceive the position of the vehicle by hearing, which is beneficial to make pedestrians around the vehicle avoid the vehicle and reduce the risk of collision between the vehicle and pedestrians.

[0025] In some embodiments of this utility model, the warning sound simulation device 30 also has a second state. When the warning sound simulation device 30 is in the second state, the warning sound simulation device 30 is disconnected from the air filter 10.

[0026] The warning sound simulation device 30 can also have a second state. In the second state, the warning sound simulation device 30 can be disconnected from the air filter 10, and the air entering the air filter 10 will not flow into the warning sound simulation device 30. The warning sound simulation device 30 does not work and does not emit a sound. When the warning sound simulation device 30 does not need to work, it can switch to the second state.

[0027] In some embodiments of the present invention, the warning sound simulation device 30 is further configured to switch to a first state when the vehicle is in pure electric mode, and the warning sound simulation device 30 is further configured to switch to a second state when the vehicle is in fuel mode.

[0028] Hybrid vehicles can have both pure electric and fuel modes. In pure electric mode, the vehicle uses a drive motor as its power source. The drive motor operates with low noise, making it difficult for pedestrians to perceive the vehicle's location by sound. Therefore, the warning sound simulation device 30 switches to its first state when the vehicle is in pure electric mode, connecting to the air filter 10 and activating. The warning sound simulation device 30 can be driven by the air flowing from the air filter 10 to emit a sound. This sound flows with the air into the muffler 20, which cancels the frequency of the sound emitted by the warning sound simulation device 30, making the sound simulate the noise of the engine 53. This further enhances the effect of the sound reminder device 1 emitting a warning sound that can be perceived by pedestrians.

[0029] When the vehicle is in fuel mode, the engine 53 can be used as the vehicle's power source. The warning sound simulation device 30 can be switched to a second state, where it is disconnected from the air filter 10. Air entering the air filter 10 will not flow into the warning sound simulation device 30, and the device will not operate or emit any sound. The air filter 10 can be connected to the vehicle's engine 53. Air filtered by the air filter 10 can flow into the engine 53. The engine 53 generates noise during operation. This noise is processed by the silencer 20 and then released into the atmosphere. The noise generated by the engine 53 can serve as a warning to pedestrians around the vehicle.

[0030] Depending on the vehicle's different power modes, the warning sound simulation device 30 can selectively switch to either a first or second state. When the vehicle is in fuel mode, the engine 53 emits noise to warn pedestrians around the vehicle, and the warning sound simulation device 30 is not activated. When the vehicle is in pure electric mode, the warning sound simulation device 30 activates, emitting a sound to warn pedestrians around the vehicle. The warning sound simulation device 30 can be used to emit a sound when the vehicle is in pure electric mode. The sound emitted by the warning sound simulation device 30, after being processed by the muffler 20, can simulate the noise of the engine 53, which helps to maintain a consistent warning sound across different power modes. The vehicle can consistently emit a warning sound in different power modes, which further helps pedestrians around the vehicle to perceive the vehicle's location by sound, allowing them to avoid the vehicle and further reducing the risk of collisions between the vehicle and pedestrians.

[0031] In some embodiments of this utility model, such as Figure 1 As shown, the sound alert device 1 may further include a control valve 40, which is connected between the alarm sound simulation device 30 and the air filter 10. The control valve 40 is used to control the alarm sound simulation device 30 and the air filter 10 to connect or disconnect, so that the alarm sound simulation device 30 switches to a first state or a second state.

[0032] A control valve 40 can be connected between the alarm sound simulation device 30 and the air filter 10. The control valve 40 can selectively open or close, controlling the connection or disconnection between the alarm sound simulation device 30 and the air filter 10. When the control valve 40 connects the alarm sound simulation device 30 and the air filter 10, the alarm sound simulation device 30 switches to its first state and emits an alarm sound. When the control valve 40 disconnects the alarm sound simulation device 30 from the air filter 10, the alarm sound simulation device 30 switches to its second state and ceases operation. By using the control valve 40, the automatic switching of the alarm sound simulation device 30's operating state is achieved, improving the efficiency of switching between the first and second states and enhancing the reliability of the sound alert device 1.

[0033] In some embodiments of this utility model, the sound reminder device 1 may further include: a controller 60, which is communicatively connected to the control valve 40 so that the controller 60 controls the control valve 40 to open or close.

[0034] The control valve 40 can be a solenoid valve, and the controller 60 can communicate with the control valve 40, controlling its opening and closing. The controller 60 can also communicate with the vehicle's powertrain. When the vehicle is in different power modes, the controller 60 can selectively open or close the control valve 40, thereby controlling the connection or disconnection between the warning sound simulation device 30 and the air filter 10, switching the warning sound simulation device 30 to either a first or second state. In pure electric mode, the controller 60 opens the control valve 40, connecting the warning sound simulation device 30 and the air filter 10, switching the warning sound simulation device 30 to the first state, and emitting a sound to alert pedestrians to the sound warning device 1. In fuel mode, the controller 60 closes the control valve 40, disconnecting the warning sound simulation device 30 from the air filter 10, switching the warning sound simulation device 30 to the second state, where it is inactive, and the engine 53 emits noise to alert pedestrians around the vehicle.

[0035] By setting the controller 60, it is beneficial to further realize the effect of automatically switching the working state of the warning sound simulation device 30, to further improve the working efficiency of the warning sound simulation device 30 when switching to the first or second state, and to further improve the reliability of the sound reminder device 1.

[0036] In some embodiments of this utility model, such as Figure 1 As shown, the alarm sound simulation device 30 may include an air compressor 31 and a reed vibrator 32, the reed vibrator 32 being connected to the air compressor 31 and the silencer 20, and the air compressor 31 being selectively connected to the air filter 10.

[0037] The reed vibrator 32 can be connected between the air compressor 31 and the silencer 20. The air compressor 31 is an air compressor, which is a type of device used for... Compressed gas The device. The air compressor 31 can be selectively connected to the air filter 10. When the controller 60 controls the control valve 40 to open, the alarm sound simulation device 30 is in the first state. The air compressor 31 can be connected to the air filter 10. The air filtered by the air filter 10 can flow into the air compressor 31. The air compressor 31 can be used to compress air. The compressed air can flow to the reed vibrator 32. The compressed air can drive the reed vibrator 32 to make a sound, so that the alarm sound simulation device 30 can make a sound. The silencer 20 cancels the frequency of the sound of the alarm sound simulation device 30 so that the sound reminder device 1 can make an alarm sound.

[0038] When the controller 60 controls the control valve 40 to close, the alarm sound simulation device 30 is in the second state. The air compressor 31 and the air filter 10 are disconnected. The air in the air filter 10 will not flow into the air compressor 31. The alarm sound simulation device 30 does not work and does not make a sound.

[0039] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the reed vibrator 32 may include: a connecting pipe 321, a mounting bracket 322, and a reed structure 323. The connecting pipe 321 connects the air compressor 31 and the silencer 20. The mounting bracket 322 is fixed inside the connecting pipe 321. The reed structure 323 includes a plurality of reeds 3231. The plurality of reeds 3231 are located inside the connecting pipe 321 and are all fixed to the mounting bracket 322. The reed structure 323 is configured to be driven by the gas flowing in from the air filter 10 to produce a sound.

[0040] The connecting pipe 321 can connect the air compressor 31 and the silencer 20. Air compressed by the air compressor 31 can flow into the silencer 20 through the connecting pipe 321. Both the mounting bracket 322 and the spring structure 323 can be disposed within the connecting pipe 321. The mounting bracket 322 can be fixed within the connecting pipe 321 and can be connected to the connecting pipe 321 by welding, snap-fitting, or other methods. As an example, the mounting bracket 322 can be constructed as a plate structure, extending radially along the connecting pipe 321, with both ends of the mounting bracket 322 along the radial direction connected to the inner wall of the connecting pipe 321. The spring structure 323 can include multiple springs 3231, and the springs 3231 can be elastic. Multiple reeds 3231 can be fixed to the mounting bracket 322. Multiple reeds 3231 can be fixedly connected to the mounting bracket 322 by welding, snap-fit ​​or other means, so that multiple reeds 3231 can be located in the connecting pipe 321. Along the radial direction of the connecting pipe 321, the reed structure 323 and the inner wall of the connecting pipe 321 are spaced apart. There is a gap between the reed structure 323 and the inner wall of the connecting pipe 321. Air flowing into the connecting pipe 321 can flow to the silencer 20 through the gap between the reed structure 323 and the inner wall of the connecting pipe 321.

[0041] When the alarm sound simulation device 30 is in the first state, the gas flowing into the alarm sound simulation device 30 from the air filter 10 can be compressed by the air compressor 31 and flow into the connecting pipe 321. The gas compressed by the air compressor 31 can flow to the silencer 20 through the gap between the reed structure 323 and the inner wall of the connecting pipe 321. When the gas compressed by the air compressor 31 flows through the reed structure 323, the gas velocity is high. The gas compressed by the air compressor 31 can generate a low-pressure zone on the surface of multiple reeds 3231. Under the action of the pressure difference, the reeds 3231 undergo elastic deformation in the direction of the gas flowing over their surface, and the reeds 3231 generate elastic force. As the gas compressed by the air compressor 31 continuously flows towards the silencer 20, the elastic force of the reed 3231 itself is greater than the pressure acting on the corresponding reed 3231. The reed 3231 will then recover its elastic deformation. Multiple reeds 3231 can continuously undergo elastic deformation and recover, enabling them to vibrate at high speed. This allows multiple reeds 3231 to generate sound wave energy, further facilitating the effect of the gas flowing from the air filter 10 driving the reed structure 323 to produce sound. The sound wave energy generated by the reed structure 323 can flow into the silencer 20 along with the gas compressed by the air compressor 31. The silencer 20 can eliminate the frequency of the corresponding sound wave energy, further facilitating the effect of the sound reminder device 1 emitting a warning sound.

[0042] In some embodiments of this utility model, such as Figure 3 As shown, the reed 3231 extends along the gas flow direction in the connecting pipe 321, and the upstream end of the reed 3231 is fixed to the mounting bracket 322 along the gas flow direction in the connecting pipe 321, and at least two reeds 3231 have different lengths along the extension direction.

[0043] The reed 3231 can extend along the gas flow direction within the connecting pipe 321, and one end of the reed 3231 can be connected to the mounting bracket 322 along the extension direction of the reed 3231. Furthermore, multiple reeds 3231 can be located on the same side of the mounting bracket 322 along the gas flow direction within the connecting pipe 321. The upstream end of the reed 3231 can be fixed to the mounting bracket 322, while the downstream end of the reed 3231 can move freely. This facilitates the high-speed vibration effect of the reed 3231 and allows the reed 3231 to produce sound under the drive of the gas flowing in from the air filter 10. Furthermore, at least two reeds 3231 have different lengths along the extension direction. When the gas flowing in from the air filter 10 passes through the two reeds 3231 with different lengths along the extension direction, the two reeds 3231 can generate sound wave energy of different orders. The sound wave energy of different orders can enter the silencer 20 along with the gas flowing in from the air filter 10. The silencer 20 can eliminate the frequency of the sound wave energy of different orders so that the sound reminder device 1 can emit a reasonable warning sound.

[0044] As an example, such as Figure 3 As shown in the embodiment of this application, the lengths of multiple reeds 3231 along the extension direction are different. When the gas flowing in from the air filter 10 passes through the multiple reeds 3231 with different lengths along the extension direction, the reed structure 323 can generate multi-order sound wave energy. The multi-order sound wave energy can enter the muffler 20 along with the gas flowing in from the air filter 10. The muffler 20 can perform directional frequency elimination of the multi-order sound wave energy. The muffler 20 can directionally eliminate high-frequency noise and simultaneously suppress low-frequency rumbling in the vehicle. This is beneficial to achieving the effect of improving the NVH performance of the vehicle while clearly amplifying the warning sound of the sound reminder device 1. It is also beneficial to enable the sound reminder device 1 to emit a reasonable warning sound, and the warning sound emitted by the sound reminder device 1 can simulate the noise of the engine 53. This is beneficial to further achieving the effect of keeping the warning sound consistent when the vehicle is in different power modes.

[0045] In some embodiments of this utility model, such as Figure 1 As shown, the sound alert device 1 may further include: an engine module connected between the air filter 10 and the muffler 20, and the warning sound simulation device 30 is further configured to be in a first state when the engine module stops working.

[0046] The engine module can be connected between the air filter 10 and the muffler 20. When the vehicle is in fuel mode, the engine module operates normally, and the warning sound simulation device 30 is in its second state. The engine module can generate noise, which can be processed by the muffler 20 and discharged into the atmosphere. The noise generated by the engine 53 can warn pedestrians around the vehicle, which helps to ensure that the sound warning device 1 can always emit a warning sound when the vehicle is in different power modes. This helps pedestrians around the vehicle to perceive the vehicle's location by sound, allowing them to avoid the vehicle and reducing the risk of collisions between the vehicle and pedestrians. When the vehicle is in pure electric mode, i.e., when the engine module is not working, the warning sound simulation device 30 can be in its first state, and the air filter 10 can selectively connect the warning sound simulation device 30 and the engine module.

[0047] As an example, such as Figure 1 As shown, the engine module may include a turbocharger 51, an intercooler 52, an engine 53, and an aftertreatment system 54. The turbocharger 51 has a pressure roller 511 and an exhaust turbine 512. The pressure roller 511 can be connected between the air filter 10 and the intercooler 52, and the exhaust turbine 512 can be connected between the engine 53 and the aftertreatment system 54. The exhaust turbine 512 can be connected to the exhaust manifold of the engine 53, and the exhaust gas discharged from the engine 53 can enter the exhaust turbine 512 through the exhaust manifold, thereby driving the exhaust turbine 512 to rotate. The pressure roller 511 can be connected to the intake system of the engine 53, and the pressure roller 511 and the exhaust turbine 512 are mounted on the same shaft. When the exhaust turbine 512 rotates, it drives the pressure roller 511 to rotate synchronously. The pressure roller 511 is connected to the air filter 10. The air in the air filter 10 is compressed by the pressure roller 511 and flows into the intercooler 52. The air then flows into the engine 53 and participates in combustion. The noise generated by the engine 53 is processed by the after-treatment module 54 and the muffler 20 and then discharged into the atmosphere so that the sound reminder device 1 can emit a warning sound.

[0048] As an example, the muffler 20 can consist of an intake flange 21, an intake pipe 22, a muffler structure 23, a first hook assembly 24, a second hook assembly 25, a third hook assembly 26, and an exhaust tailpipe 27. The intake flange 21 is connected to the aftertreatment mechanism 54 in the engine module. The muffler structure 23 is used to process the noise flowing into the muffler 20 and the noise generated by the engine 53. The exhaust tailpipe 27 can be connected to the atmospheric environment. The first hook assembly 24, the second hook assembly 25, and the third hook assembly 26 can all be welded to the muffler structure 23, and can all be connected to the frame or body via rubber hangers. The connecting pipe 321 of the reed vibrator 32 can be connected to the intake pipe 22.

[0049] In some embodiments of this utility model, when the vehicle is in fuel mode, the controller 60 controls the control valve 40 to close, the warning sound simulation device 30 is disconnected from the air filter 10, the engine module works, and the noise generated by the engine module is discharged into the atmosphere after being processed by the silencer 20. The noise generated by the engine module can warn pedestrians around the vehicle.

[0050] When the vehicle is in pure electric mode, the engine module stops working, the controller 60 controls the control valve 40 to open, connecting the air filter 10 and the air compressor 31. Air from the air filter 10 flows into the air compressor 31, and the compressed air flows to the reed vibrator 32. The compressed air flows through the gap between the reed structure 323 and the inner wall of the connecting pipe 321, driving the reed structure 323 to produce a sound. The reed structure 323 includes multiple reeds 3231 of different lengths along its extension direction. The reed structure 323 generates multi-order sound wave energy, which can enter the silencer 20 along with the compressed air from the air compressor 31. The silencer 20 performs directional frequency cancellation of the multi-order sound wave energy, which helps to achieve the function of the sound warning device 1 alerting pedestrians around the vehicle when the vehicle is in pure electric mode. The warning sound emitted by the sound warning device 1 can simulate the noise of the engine 53, which helps to further ensure that the warning sound remains consistent across different power modes of the vehicle.
