Description

Technical Field

[0001] This invention belongs to the field of automotive braking. Specifically, this invention relates to a venting switch structure for a reservoir cap of an off-road vehicle and the vehicle itself. Background Technology

[0002] The reservoir caps on existing mature off-road vehicles are no different from those on ordinary passenger vehicles. Existing off-road vehicles use ordinary reservoir caps, which, due to their simple structure, cannot prevent water from entering when wading through deep water or floating. Therefore, it is impossible to prevent water from entering through the vent hole of the reservoir cap, which can cause the braking system to fail due to water ingress when the driver accidentally steps on the brake while wading or floating.

[0003] Utility model patent No. 204038122U, published on December 24, 2014, discloses a type of clamping spout liquid reservoir. It includes a spout and a lid fastened by a clamping mechanism. The clamping mechanism comprises three spout flanges and corresponding lid flanges. The spout flanges are evenly distributed on the outer circumference of the spout, with their upper edges flush with the end face of the spout and their lower edges forming a downwardly sloping arc edge. A limiting protrusion is located at the tail of the lower arc edge, and a positioning recess is located in the middle. The lid flanges are evenly distributed on the inner circumference of the lid, with their lower edges flush with the end face of the lid opening and their upper edges forming an upper arc edge with the same slope as the lower arc edge of the spout flanges. A limiting protrusion is located at the tail of the upper arc edge, and a positioning protrusion in the middle corresponds to the positioning recess of the spout flanges. This clamping spout liquid reservoir cannot prevent water ingress into the braking system and cause failure when the vehicle is wading or floating in water. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a venting switch structure for the reservoir cap of an off-road vehicle and a vehicle that prevents the braking system from failing due to water ingress during wading or floating conditions.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] The venting switch structure of the reservoir cap of this type of off-road vehicle includes a reservoir with a pipe, the cap being located at the top of the pipe, an operating switch connected to the cap, an air passage structure inside the cap, and a limit structure on the operating switch.

[0007] The air passage structure includes an air chamber, a boss is provided in the middle of the lid, the air chamber is located in the boss, a first vent hole is provided at the top of the boss, a second vent hole is provided in the middle of the lid, a gap is provided between the operating switch and the top of the boss, the first vent hole connects the gap and the air chamber, and the second vent hole connects the air chamber and the pipe.

[0008] The limiting structure includes a claw, the operating switch has a claw in the middle, the claw is a hollow structure, the claw extends into the first vent hole, the end of the claw has a barb, the diameter of the barb is larger than the diameter of the first vent hole, and the end of the barb has a guide slope.

[0009] The operating switch is threadedly connected to the kettle lid, and the kettle lid is threadedly connected to the pipe.

[0010] The inner side of the pipe is provided with a first step, and an anti-surge sealing gasket is provided between the lid and the top of the pipe. The anti-surge sealing gasket is provided with a venting gap in the middle, and the venting gap connects the second vent and the pipe. The anti-surge sealing gasket is adapted to the inner side of the lid.

[0011] A sealing ring is provided between the bottom of the operating switch and the lid of the kettle, and the outer diameter of the sealing ring is larger than the outer diameter of the bottom of the operating switch.

[0012] The operating switch has protrusions at both ends, and the protrusions and the operating switch are an integral structure. The end of the protrusion is an arc-shaped structure.

[0013] The lid has evenly distributed protrusions on its side and a flange at its end; the pipe has a second step on its outside and the bottom of the lid and the bottom of the second step are on the same plane.

[0014] The liquid storage container is provided with a connecting bracket on its side, the connecting bracket is provided with a connecting hole, the connecting brackets are arranged in pairs, and the connecting bracket is provided with a reinforcing rib.

[0015] A vehicle including the vent switch structure for the reservoir cap of the aforementioned off-road vehicle.

[0016] The technical advantages of this invention are as follows: The venting switch structure of the reservoir cap for off-road vehicles utilizes this invention. The cap structure is redesigned, and an operable switch structure for adjusting the gas discharge channel is installed on the cap. This redesign of the gas discharge channel alters the gas discharge path, increasing the difficulty for external water to enter the reservoir, preventing water ingress into the brake fluid, and resolving the risk of brake fluid ingress during wading and floating, thus ensuring reliable braking performance. A limit structure is designed on the operating switch to ensure stable gas discharge and prevent driver error. The operating switch uses a threaded connection for easy adjustment of the gas discharge channel opening. The air chamber, anti-surge sealing gasket, and second-step structure block and contain the brake fluid, preventing overflow and ensuring long-term reliable braking performance. This venting switch structure for the reservoir cap of off-road vehicles is simple in structure, ingeniously designed, and reliably strong, and can be retrofitted to existing reservoirs.

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0022] like Figure 1 and Figure 2 As shown, the venting switch structure of the liquid reservoir cap of the off-road vehicle includes a liquid reservoir 1, a pipe 2, a cap 3 located at the top of the pipe 2, an operating switch 4 connected to the cap 3, an air passage structure inside the cap 3, and a limit structure on the operating switch 4.

[0023] The vent switch structure of the reservoir cap in this off-road vehicle alters the gas passage path, significantly increasing the difficulty for external water to enter the reservoir 1. When the off-road vehicle is wading through deep water or floating, water is completely prevented from entering through the vent hole in the reservoir cap 3, avoiding brake failure and solving the problem of the reservoir 1 being unable to waterproof in existing off-road vehicles during wading and floating modes. By integrating the vent switch into the reservoir cap 3, in conjunction with the reservoir 1, the driver can control whether the brake fluid reservoir is vented before wading, preventing brake system failure due to accidental braking during wading or floating. Furthermore, no modification to the existing reservoir 1 structure is required; only the cap 3 of this invention needs to be replaced and the operating switch 4 installed, thus effectively reducing manufacturing and development costs.

[0024] like Figure 1As shown, the air passage structure includes an air chamber 6, a boss 5 in the middle of the lid 3, the air chamber 6 located inside the boss 5, a first vent 7 at the top of the boss 5, a second vent 8 in the middle of the lid 3, and a gap between the operating switch 4 and the top of the boss 5. The first vent 7 connects the gap and the air chamber 6, and the second vent 8 connects the air chamber 6 and the pipe 2. Compared with the existing air passage structure, the above structure changes the gas flow path. Gas flows from inside the reservoir 1 through the second vent 8, the air chamber 6, the first vent 7, and the gap between the operating switch 4 and the boss 5, and then exits to the outside through the gap between the operating switch 4 and the sealing ring 12. This gap serves as a gas discharge channel, and the size of this gas discharge channel can be adjusted by changing the relative position of the operating switch 4 and the lid 3. The air chamber 6 provides initial buffering for the gas, improving stability. The air chamber 6, in conjunction with the anti-surge sealing gasket 13, also prevents the brake fluid in the reservoir 1 from overflowing, thus improving its anti-surge effect.

[0025] like Figure 1 As shown, the limiting structure includes a claw 9. The operating switch 4 has a claw 9 in the middle. The claw 9 is a hollow structure that extends into the first vent hole 7. The end of the claw 9 has a barb 10 with a diameter larger than that of the first vent hole 7. The end of the barb 10 has a guide slope 11. The design of the claw 9 limits the adjustment of the gas emission channel size and also prevents the operating switch 4 from falling off. In the above structure, the distance from the end of the claw 9 to the first vent hole 7 is the maximum displacement distance of the operating switch 4. That is, when the driver rotates the operating switch 4 to the maximum distance, the barb 10 will abut against the inner side of the boss 5, achieving the limiting effect and preventing the operating switch 4 from falling off. At this time, the gap between the bottom of the operating switch 4 and the sealing ring 12 reaches its maximum. Even if the driver rotates the operating switch 4 again, the gap will not widen, reducing the difficulty of operation for the driver and avoiding driver error. The opening of the gas emission channel remains stable, effectively ensuring the stability of ventilation. The guide slope 11 on the barb 10 can reduce the resistance of the claw 9 during installation and prevent damage due to excessive force during installation. The middle part of the claw 9 is hollow. This design allows the claw 9 to retract inward at a certain angle during installation, so that the claw 9 can smoothly enter the first vent hole 7 along its guide slope 11. As an anti-disengagement structure for the operating switch 4, it prevents the operating switch 4 from easily coming loose and forms a solid structure.

[0026] like Figure 1 As shown, the operating switch 4 is threadedly connected to the lid 3, and the lid 3 is threadedly connected to the pipe 2. The operating switch 4 and the lid 3 are connected by threads. During operation, the operating switch 4 moves up and down on the lid 3 to adjust the opening of the gas emission channel. The adjustment amount changes evenly with each rotation of the operating switch 4, ensuring stable ventilation function.

[0027] like Figure 1As shown, a first step 18 is provided on the inner side of the pipe 2, and an anti-surge sealing gasket 13 is provided between the reservoir cap 3 and the top of the pipe 2. A vent 14 is provided in the middle of the anti-surge sealing gasket 13, which connects the second vent hole 8 and the pipe 2. The anti-surge sealing gasket 13 is adapted to the inner side of the reservoir cap 3. Since the brake fluid in the reservoir 1 inevitably surges when the vehicle is in motion, an anti-surge sealing gasket 13 is added between the reservoir cap 3 and the pipe 2 to seal the reservoir 1 and the reservoir cap 3 and prevent the brake fluid from overflowing. This gasket 13 is used to meet the venting and anti-surge functions of the reservoir 1 under normal braking requirements. To avoid the anti-surge sealing gasket 13 affecting the venting function of the reservoir 1, a vent 14 is provided on the anti-surge sealing gasket 13 to connect the second vent hole 8 and the pipe 2. This ensures that gas is only discharged from the vent 14 while blocking the brake fluid in the reservoir 1. The first step 18 increases the volume at the top of the pipe 2. Combined with the use of the anti-surge sealing gasket 13, it can effectively prevent the brake fluid in the reservoir 1 from overflowing from the vent 14.

[0028] like Figure 1 As shown, a sealing ring 12 is provided between the bottom of the operating switch 4 and the lid 3. The outer diameter of the sealing ring 12 is larger than the outer diameter of the bottom of the operating switch 4. Both the sealing ring 12 and the anti-surge sealing gasket 13 are made of rubber, which is elastic and can deform under pressure. The sealing ring 12 and the lid 3 of the liquid storage vessel have a tight-fitting structure. Due to the elasticity of the sealing ring 12, the contact between the operating switch 4 and the lid 3 is changed to a flexible contact. When the operating switch 4 is turned to close, it can press down a certain distance, forming a reliable sealing effect for the operating switch 4. The outer diameter of the sealing ring 12 is larger than the outer diameter of the bottom of the operating switch 4. After closing, there is no gap between the operating switch 4 and the sealing ring 12, ensuring that the sealing ring 12 can fully contact the operating switch 4, thereby further improving the sealing effect.

[0029] like Figure 2 As shown, the operating switch 4 has protrusions 17 at both ends, which are integral with the operating switch 4. The end of the protrusion 5 is arc-shaped. The protrusions 17 and the operating switch 4 are integrally formed, ensuring reliable strength. The arc-shaped end of the protrusions 17 reduces stress and prevents deformation. The protrusions 17 increase the torque required for manual rotation by the driver, reduce the resistance to rotating the operating switch 4, and facilitate the driver's judgment of the number of rotations of the operating switch 4, thus quickly adapting to the required opening of the gas exhaust channel in off-road vehicle conditions such as wading and floating. A position sensor can be added to the operating switch 4 to enable interaction between the oil reservoir cap status and the vehicle's infotainment system.

[0030] like Figure 2As shown, the lid 3 has evenly distributed protrusions 15 on its side, and a flange 16 at its end. A second step 19 is provided on the outside of the pipe 2, and the bottom of the lid 3 is flush with the bottom of the second step 19. The protrusions 15 increase the friction of the lid 3, facilitating its installation and removal. The flange 16 strengthens the end of the lid 3, extending its service life. The second step 19 not only expands the internal space of the pipe 2, facilitating the construction of the first step 18, but also serves as a reference point for determining whether the lid 3 is properly installed. When the bottoms of the lid 3 and the second step 19 are flush, it ensures the lid 3 is installed in the correct position, making the connection secure and reliable.

[0031] like Figure 2 As shown, the liquid reservoir 1 has a connecting bracket 20 on its side, and the connecting bracket 20 has a connecting hole 21. The connecting brackets 20 are arranged in pairs, and each connecting bracket 20 has a reinforcing rib 22. The liquid reservoir 1 can be stably installed on the vehicle body through a pair of connecting brackets 20, which also facilitates subsequent maintenance. The reinforcing rib 22 is an integral structure with the connecting bracket 20. The reinforcing rib 22 can improve the structural strength of the connecting bracket 20, ensuring that the connecting bracket 20 is not easily deformed, thereby ensuring that the liquid reservoir 1 is firmly installed.

[0032] A vehicle including the vent switch structure for the reservoir cap of the aforementioned off-road vehicle.

[0033] The venting switch structure of the reservoir cap of this off-road vehicle has been modified by changing the structure of the reservoir cap 3, removing the venting channel of the ordinary reservoir 1, and redesigning the venting channel structure. Together with the anti-surge sealing gasket 13 and the reservoir cap 3, it can realize the functions of venting the reservoir 1 and preventing brake fluid surge under normal braking requirements.

[0034] The implementation process is as follows: During wading and floating operations, the driver can operate the device by turning the switch 4 to the right, causing the threaded part of the reservoir cap 3 to move downwards, compressing the sealing ring 12 to form a seal. At this time, the reservoir 1 is completely isolated from the outside atmosphere, preventing the risk of water ingress. After leaving the wading and floating conditions, the driver can operate the switch 4 to the left, causing the threaded part of the reservoir cap 3 to move upwards, releasing the pressure on the sealing ring 12 and thus breaking the seal. At this time, the reservoir 1 is in contact with the outside atmosphere, and braking operations can be performed normally.

[0035] The venting switch structure of the reservoir cap in this off-road vehicle features a redesigned cap 3 with an adjustable venting switch 4. This redesign alters the venting path of the reservoir 1, making it more difficult for external water to enter and preventing brake fluid ingress. This addresses the risk of brake fluid ingress during wading and floating, ensuring reliable braking performance. A limit structure on the operating switch 4 ensures stable venting and prevents driver error. The threaded connection of the operating switch 4 allows for easy adjustment of the venting channel opening. The air chamber 6, anti-surge sealing gasket 13, and second step 19 structure effectively block and contain brake fluid, preventing overflow and ensuring long-term reliable braking performance. This venting switch structure for the reservoir cap of this off-road vehicle is simple, ingeniously designed, and reliably strong, and can be retrofitted to existing reservoirs.

[0036] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
