Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle exhaust systems and silencing devices, and particularly relates to an intelligent silencing reminding device with a wading safety reminding function, which is particularly suitable for special vehicles such as all-terrain vehicles, off-road vehicles and the like that need to frequently pass through wading sections. BACKGROUND

[0002] In the prior art, the exhaust system of an all-terrain vehicle usually adopts a single muffler structure, and the engine exhaust noise is reduced by arranging multiple layers of baffle plates, sound-absorbing materials or special-shaped silencing chambers inside the muffler. Such a muffler can effectively reduce noise pollution and meet environmental protection requirements, but when the vehicle is driving in water, since the exhaust pipe is relatively low, when the water level exceeds the height of the exhaust pipe outlet, the water flow will enter the inside of the muffler through the exhaust pipe. At this time, the driver often has difficulty in timely sensing that the vehicle has entered a dangerous deep water area, and is prone to continue driving, resulting in engine water damage.

[0003] In order to solve the wading problem, some existing technologies extend the exhaust pipe outlet to a higher position of the vehicle, so as to increase the wading depth. However, this method has obvious defects: on the one hand, it changes the appearance of the vehicle, affecting the aesthetics and aerodynamic performance; on the other hand, an excessively high exhaust pipe may be damaged when the vehicle passes through low obstacles or forests, limiting its practicality. In addition, some technical solutions set a water level sensor and an alarm device on the instrument panel to remind the driver, but this solution requires additional sensors, lines and alarm devices, increasing the complexity and cost of the system, and the reminder may fail due to sensor failure.

[0004] In addition, some existing exhaust systems have a drainage structure inside the muffler, which can drain the accumulated water after wading, but still lack an active reminding function and cannot timely warn the driver during wading. The driver still needs to rely on experience to judge the water depth, and for users who are not familiar with the road conditions, there is a great safety hazard. Especially at night or in poor visibility conditions, the driver is more difficult to accurately judge the wading depth, and is prone to misjudgment, resulting in damage to the vehicle.

[0005] Therefore, how to timely and reliably remind the driver of wading without changing the overall structure of the vehicle and without adding complex electronic equipment has become a technical problem to be solved in the design of the exhaust system of an all-terrain vehicle. SUMMARY

[0010] Preferably, the second partition is provided with a feedback pipe, the feedback pipe being used for feeding back the sound in the third chamber to the second chamber.

[0011] Preferably, the blocking control structure comprises: a plugging assembly movably installed in the lower branch pipe and used for plugging the communication hole in an unfolded state; an unfolding driving member used for driving the plugging assembly to unfold; and a floating assembly driving the unfolding driving member to move through the buoyancy so that the unfolding driving member drives the plugging assembly to unfold.

[0012] Preferably, the plugging assembly is hinged by two half-circular assembly frames, and a plugging film is adhered between the two assembly frames; when the two assembly frames are rotated to be completely unfolded, the two assembly frames are attached to the wall of the first partition and form a complete circle, and the plugging film completely plugs the communication hole.

[0013] Preferably, the delivery pipe is bifurcated to form a mounting support pipe coaxially arranged with the communication hole; the deployment drive is slidingly mounted in the mounting support pipe and coaxially arranged with the communication hole, and part of the blockage control structure is movably mounted in the mounting support pipe and passes through the communication hole, and the other part of the blockage control structure movably passes through the mounting support pipe into the second chamber.

[0014] Preferably, the floating assembly comprises a floating rod and a floating ball, the lower end of the floating rod is connected to the floating ball, and the upper end of the floating rod is movably inserted into the movable slot of the deployment drive; the floating rod is further rotatably connected to a connecting plate arranged at the lower end of the mounting support pipe, so that the floating rod can rotate under the buoyancy of the floating ball and push the deployment drive to move through the rotation of the upper end of the floating rod in the movable slot.

[0019] Reasonable structural design: By setting up a three-chamber partition structure in the lower silencer, the exhaust gas flow path can be effectively controlled; the blocking control structure adopts a combination design of sealing component, deployment drive component and floating component. The buoyancy of the float drives the float rod to rotate, which in turn pushes the deployment drive component to make the sealing component deploy and block the connecting hole. The structure is compact and the operation is reliable.

[0020] Good recoverability: After driving out of the flooded section and draining the water, the float and float rod automatically reset under their own weight, and the sealing component closes again under the rebound force of the torsion spring, restoring the normal noise reduction state.

Detailed Implementation

[0024] Example: This embodiment provides an intelligent noise reduction warning device for all-terrain vehicles wading through water. It is mainly used in wading sections with deep water. By setting up upper and lower mufflers and differentiating their noise reduction effects, when driving on a normal road, the upper muffler 40 blocks the flow, and the exhaust gas produced by the engine can only be discharged from the lower muffler 50 with better noise reduction effect, resulting in a quiet exhaust sound. However, when passing through a water section and the water enters the lower muffler 50, the inflowing water drives a specific structure inside the lower muffler 50 to activate. The activation of this specific structure can switch the flow state of the two mufflers, so that the lower muffler 50 blocks the flow, while the upper muffler 40 can be connected to the outside. Therefore, the engine exhaust gas is redirected to be discharged from the upper muffler 40 with relatively poor noise reduction effect, resulting in a noticeable noise when it is discharged, thus serving as a warning to remind the rider to quickly leave the water section.

[0025] refer to Figure 1 In this embodiment, the intelligent muffler reminder device is installed on the frame 01 of the all-terrain vehicle and connected to the engine of the all-terrain vehicle, and then combined with... Figure 2 References include: The main connecting pipe 10 is connected to the engine via the engine end mounting bracket 11; Catalyst 20, connected to main pipe 10, is used to convert the main harmful substances in engine exhaust into low-toxicity substances; The exhaust manifold 30 is connected to the catalytic converter 20 and has two branch pipes, namely the upper branch pipe 31 and the lower branch pipe 32. The upper muffler 40 is hollow inside and connected to the upper branch pipe 31. The upper branch pipe 31 is equipped with a sensing solenoid valve 70. The sensing solenoid valve 70 is used to control the connection between the upper branch pipe 31 and the upper muffler 40. When the all-terrain vehicle is driving on a normal road section, the sensing solenoid valve 70 is in the closed state. The lower muffler 50 has a chamber that communicates with the lower bifurcation pipe 32. The chamber is equipped with a muffler structure (the muffler structure is existing technology, so its structure will not be described in detail here, and its structure is not shown in the figure). The other end of the lower muffler 50 is connected to an exhaust pipe 51, which is located outside the lower muffler. Blocking control structure 60 (e.g.) Figure 3 As shown), this is the core structural design of the device. It is movably installed within the chamber, where buoyancy is generated by the water entering the chamber. This buoyancy then drives its own movement to block the flow of the lower branch pipe 32 within the chamber. A pressure sensor 80 (as shown) is also installed within the chamber. Figure 4As shown in the figure, the pressure sensor 80 is connected to the solenoid valve 70 and is used to control the opening or closing of the solenoid valve 70.

[0026] The above solution uses water entering the lower muffler to drive the blocking control structure 60 to start, blocking the flow of the lower branch pipe 32. This causes the air pressure in the lower muffler 50 chamber to decrease instantly. After sensing the decrease in air pressure, the air pressure sensor 80 controls the sensing solenoid valve 70 to open, allowing the engine exhaust gas to be discharged from the upper muffler 40. However, the upper muffler 40 is hollow, which will generate obvious noise when the exhaust gas is discharged, thus achieving the warning function.

[0027] Specifically, refer to Figure 3 The lower silencer 50 has three chambers formed by two partitions. The chambers and partitions are arranged in the following order: first chamber 54, first partition 52, second chamber 55, second partition 53, and third chamber 56. The lower branch pipe 32 passes through the first chamber 54 and communicates with the first partition 52 through the communication hole 521 (e.g., ...) of the first partition 52. Figure 6 (As shown) The sealed connection is provided, and the connecting hole 521 is also connected to the discharge pipe 57. The discharge pipe 57 passes through the second partition 53 to the third chamber 56, which is connected to the exhaust pipe 51. The pressure sensor 80 and the silencing structure are both installed in the third chamber 56. The second partition 53 is also provided with a return pipe 58, which can transmit the sound from the third chamber 56 back to the second chamber 55 to increase the noise processing space and further reduce the noise. However, this return pipe 58 also allows water entering the third chamber 56 from the exhaust pipe 51 to re-enter the second chamber 55 through the return pipe 58.

[0028] Among them, reference Figure 3 The discharge pipe 57 is also branched into an installation support pipe 59 coaxial with the connecting hole 521. Part of the blocking control structure 60 is movably installed in the installation support pipe 59 and passes through the connecting hole 521. Another part of the blocking control structure 60 moves through the installation support pipe 59 to the second chamber 55.

[0029] Specifically, refer to Figure 4 , Figure 5 The blocking control structure 60 includes: The sealing assembly 61 is housed in the lower bifurcated tube 32 and hinged to its inner wall. It is composed of two semi-circular frames 611 hinged together. A sealing membrane 612 is also adhered between the two frames 611, so that the rotation of the two frames 611 can drive the sealing membrane 612 to unfold. When rotated to fully unfold, the two frames 611 are attached to the wall of the first partition 52 and form a complete circle. This circle is coaxial with the connecting hole 521 and makes the sealing membrane 612 completely block the connecting hole 521. The unfolding drive component 62 is slidably installed in the mounting support tube 59 and coaxially arranged with the connecting hole 521, and is used to drive the two sets of frames 611 of the sealing assembly 61 to rotate and unfold. The floating assembly 63 includes a float 631 with a float ball 632 connected to its lower end. The upper end of the float 631 passes through the mounting support tube 59 and is movably inserted into the movable slot 624 of the deployment drive component 62. The float 631 is also rotatably hinged to a connecting plate 64 located at the lower end of the mounting support tube 59, allowing the float 631 to rotate under the buoyancy of the float ball 632. The rotating upper end of the float 631 and its mating movable slot 624 then drive the deployment drive component 62 to move. The float 631 can be a single piece or formed by fixing multiple rods of different shapes and diameters together.

[0030] The float 631 has adequate space for movement at the point through which it passes through the mounting support pipe 59, ensuring smooth bidirectional rotation. The upper end of the float 631 is arc-shaped with a suitable gap between it and the movable groove 624, preventing it from getting stuck during rotation and allowing it to smoothly push against the groove. The lower end of the float 631 is angled away from the sealing assembly 61 to restrict its rotation direction under the buoyancy of the float ball 632, ensuring that when water enters, the upper end of the float 631 can only rotate towards the sealing assembly 61. The upper part of the float 631 is bent so that when it is angled, its upper end can be vertically inserted into the movable groove 624.

[0031] The principle of the aforementioned blocking control structure 60 is as follows: As water gradually enters the second chamber 55, the float 632 gradually rises and drives the float 631 to rotate around the hinge point as the water level rises. This causes the upper end of the float 631 to rotate in the movable groove 624, thereby pushing the unfolding drive 62 toward the sealing assembly 61. This causes the two sets of frames 611 of the sealing assembly 61 to rotate and unfold, thereby driving the sealing membrane 612 to unfold until it completely blocks the connecting hole 521, thus blocking the flow of the lower branch pipe 32.

[0032] Furthermore, the specific structure of the deployment drive 62 driving the sealing assembly 61 to deploy is as follows: refer to Figure 5 The unfolding drive component 62 sequentially includes a pushing end 621, a tapered connecting section 622, and a sliding straight section 623, as shown in the reference section. Figure 6 , Figure 7 The frame 611 has a crossbar 6112, and a pushing protrusion 6113 is provided in the middle of the crossbar 6112. When the two frames 611 are closed, the two pushing protrusions 6113 are oriented opposite to each other (e.g., Figure 6As shown), in the closed state, the pushing end 621 can be separated from and abutted against the two pushing protrusions 6113, and its diameter is greater than the distance between the two opposing pushing protrusions 6113 and less than the distance between the two crossbars 6112; in addition, the tapered connecting section 622 passes through the connecting hole 521, and the movable groove 624 is opened in the sliding straight section 623.

[0033] Therefore, when the unfolding drive 62 is pushed towards the sealing assembly 61 by the floating component 63, the pushing end 621 gradually approaches and pushes the two pushing protrusions 6113, causing the two pushing protrusions 6113 to rotate relative to each other through the hinged crossbar 6112, thereby driving the two frames 611 to rotate relative to each other until fully unfolded, and at the same time driving the sealing membrane 612 to unfold.

[0034] After the sealing membrane 612 expands to block the connecting hole 521, the air pressure sensor 80 and the sensing solenoid valve 70 cause exhaust gas to be discharged from the upper muffler 40 to generate a noise warning. After the rider is aware of the warning and has driven out of the flooded section, they should promptly drain the water from the lower muffler 50 and restore the function of the lower muffler 50. To this end, the present invention further improves the above structure.

[0035] Specifically, when the lower muffler 50 is installed on the frame 01 of the all-terrain vehicle, it is installed at an angle, with the first chamber 54 located at a lower position and the third chamber 56 located at a higher position (e.g., Figure 1 (As shown). Since the first chamber 54 is completely isolated from the second chamber 55, and the second chamber 55 is connected to the third chamber 56, a drain hole is provided at the bottom of the second chamber 55 near the first chamber 54. The drain hole is sealed by an existing threaded sealing member 90 (as shown). Figure 3 (As shown). Therefore, after exiting the flooded section, the cyclist can screw open the sealing component 90 to allow the water in the second chamber 55 and the third chamber 56 to drain out through the drain hole.

[0036] Furthermore, to ensure that the blocking control structure can return to its normal initial state after the water is drained, when both frames 611 are fully extended, the upper end of the float 631 remains within the movable groove 624, and a torsion spring (not shown in the figure) is provided at the hinge joint of the two frames 611.

[0037] The principle by which the above structure restores this device to its normal state is as follows: After the water is discharged, the float 632 and the float rod 631 rotate downwards under their own weight, causing the upper end of the float rod 631 to rotate in the opposite direction. The float rod 631 then drives the push end 621 to retract from between the two crossbars 6112 through the movable groove 624, causing the two sets of frames 611 to rotate in opposite directions and reclose under the rebound force of the torsion spring. As a result, the connecting hole 521 is exposed again, allowing it to reconnect with the lower branch pipe 32. Therefore, some of the exhaust gas emitted by the engine can be discharged from the lower muffler 50, causing the air pressure in the chamber of the lower muffler 50 to increase instantaneously. After sensing the increase in air pressure, the air pressure sensor 80 controls the sensing solenoid valve 70 to close again, so that all exhaust gas can only be discharged from the lower muffler 50, which has a better silencing effect. This also restores the normal state of the device.

[0038] Furthermore, to make the control of the air pressure sensor 80 more precise, a certain air pressure change difference can be preset. When the decrease in air pressure within a certain time is within the set range, the solenoid valve 70 is controlled to open; when the increase in air pressure within a certain time is within the set range, the solenoid valve 70 is controlled to close.

[0039] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the patent. Those skilled in the art should understand that, within the scope of the present invention's concept, various equivalent replacements or modifications can be made to components such as the blocking control structure, floating components, and chamber structures, as long as they can achieve the technical effect of automatically switching the silencing mode using water buoyancy, and should fall within the protection scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the present invention's technical solution.
