Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to a steering dust cover for a vehicle and the vehicle itself. Background Technology

[0002] In automotive research and development, sealing performance is a crucial indicator affecting the customer's driving experience. Sealing performance directly impacts a car's ability to withstand rain, water wading, and dust and dirt, and also significantly influences its sound insulation and air conditioning performance. Furthermore, the steering system's main shaft requires an opening in the vehicle body to insert into the passenger compartment from the outside; poor sealing of this opening will inevitably affect the vehicle's sealing performance. Currently used steering system dust covers offer some sealing, but their effectiveness is significantly reduced when there are large manufacturing or assembly errors in components, or when the vehicle experiences bumps during dynamic driving.

[0003] Therefore, improving the sealing effect of dust covers is a technical problem that urgently needs to be solved today. Utility Model Content

[0004] This application provides a steering dust cover for a vehicle and a vehicle that improves the sealing effect.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a steering dust cover for a vehicle, comprising: a dust cover body and a first seal; the dust cover body defines a receiving space for accommodating a steering shaft, the dust cover body has a first centerline, the dust cover body includes a first mounting portion, which protrudes toward the first centerline along a first direction to form a recess suitable for fitting with a vehicle body sheet metal, the first direction being perpendicular to the first centerline; the first seal is fixed to the first mounting portion and located in the recess, the first seal is constructed as an elastic member to press against the vehicle body sheet metal when the vehicle body sheet metal fits into the recess.

[0007] The steering dust cover proposed in this application embodiment adds a first sealing element to the traditional dust cover. Even if there are minor errors in manufacturing and assembly, or if the dust cover deforms when the vehicle is moving and experiencing bumps, the first sealing element can still press against the body sheet metal. This prevents the first sealing element from having too small a contact area with the body sheet metal, thus maintaining the sealing effect and improving dustproof, waterproof, and soundproof performance.

[0008] Optionally, the first mounting portion includes a first portion and a second portion extending along a first centerline, with at least a portion of the first portion and the second portion spaced apart to form a recess, and a first seal is disposed on the first portion.

[0009] In the above scheme, the first mounting portion comprises at least partially spaced first and second parts, the first seal is arranged on the first part, at this time the vehicle body panel is located in the space between the first and second parts, the first seal plays a sealing role between the first part and the vehicle body panel, the first seal is tightly attached to the surface of the panel through elastic deformation, effectively filling the assembly gap between the first part and the vehicle body panel, and significantly improving the dustproof, waterproof and sound insulation effects.

[0010] Optionally, along the first direction, the distance between the first part and the second part along the first center line gradually decreases.

[0011] In the above scheme, as the distance gradually decreases, when the vehicle body panel is fitted into the recess, the contact between the first seal and the vehicle body panel will be more closely. Because of this gradual structure, the first seal can still press against the vehicle body panel when the distance between the first part and the vehicle body panel changes at different positions, thereby better filling the possible gaps and improving the integrity of the seal, effectively preventing dust, water and noise from entering.

[0012] Optionally, the steering dust cover further comprises a second seal, the second seal is fixed to the second part and located in the recess.

[0013] In the above scheme, two seals are arranged on the first and second parts respectively, which can seal from both sides of the center line along the vehicle body panel, more comprehensively covering the contact area between the recess and the vehicle body panel, reducing the sealing dead angle, and at the same time, the first and second seals form a double sealing defense line, even if the sealing performance of the first seal decreases in some cases, such as slight wear after long-term use, local sealing pressure changes caused by vehicle bumping, etc., the second seal can still continue to block the invasion of dust, water and noise, greatly improving the overall sealing reliability of the steering dust cover.

[0014] Optionally, the first seal has a first cavity inside, the first seal is provided with a first exhaust hole, and the first exhaust hole communicates the first cavity with the outside.

[0015] In the above scheme, the volume of the first cavity inside the first seal can decrease as the gas is discharged from the first exhaust hole, which can improve the deformation degree of the first seal and further increase the contact area between the first seal and the vehicle body panel, thereby further improving the sealing effect of the first seal between the vehicle body panel and the first part.

[0016] Optionally, the first seal is configured as a first sealing ring around the first center line.

[0017] In the above scheme, the annular structure of the sealing ring enables it to uniformly apply sealing pressure in the entire circumferential direction when it is extruded by the vehicle body panel, so that the contact between the first sealing element and the vehicle body panel is more closely ensured, the sealing effect is more stable, and the probability of local sealing failure caused by uneven pressure is reduced.

[0018] Optionally, the steering dust cover further comprises a third sealing element, the third sealing element is fixed to the first mounting portion and located in the recess, and along the first center line extension direction, the third sealing element is at least partially spaced apart from the first sealing element to clamp the vehicle body panel when the vehicle body panel is fitted in the recess.

[0019] In the above scheme, when impurities such as dust, moisture, and oil stains from the outside attempt to intrude, the first sealing element can first block a part of the impurities, and the remaining impurities that are not completely blocked will be further blocked by the third sealing element when reaching the third sealing element, thereby greatly improving the reliability of the sealing and effectively preventing impurities from entering the internal space that needs to be sealed.

[0020] Optionally, the third sealing element has a second cavity inside, and the third sealing element is provided with a second exhaust hole, the second exhaust hole communicates the second cavity with the outside.

[0021] In the above scheme, the volume of the second cavity inside the third sealing element can become smaller as the gas is exhausted from the second exhaust hole, and such arrangement can improve the deformation degree of the third sealing element, further increase the contact area between the third sealing element and the vehicle body panel, and thereby further improve the sealing effect of the third sealing element between the vehicle body panel and the recess.

[0022] Optionally, the third sealing element is configured as a third sealing ring around the first center line.

[0023] In the above scheme, the annular structure of the sealing ring enables it to uniformly apply sealing pressure in the entire circumferential direction when it is extruded by the vehicle body panel, so that the contact between the third sealing element and the vehicle body panel is more closely ensured, the sealing effect is more stable, and the situation of local sealing failure caused by uneven pressure is avoided.

[0043] In the process of automobile research and development design, the sealing performance is an important indicator affecting the customer driving experience. The sealing performance not only directly relates to the ability of the automobile to rain, wade and prevent dust and dirt, but also has an important influence on the sound insulation performance and air conditioning performance of the automobile. On the other hand, the main shaft of the automobile steering system must be holed on the vehicle body when it is inserted into the passenger cabin from the outside. If the hole is poorly sealed, it will certainly affect the sealing performance of the vehicle. The dust cover used in the industry at present can play a certain sealing role, but when there is a large manufacturing and assembly error in the parts, or when the vehicle bounces during dynamic driving, the sealing effect of the current sealing structure will be greatly reduced.

[0044] The prior art utilizes the elasticity of the rubber dust cover to tightly adhere to the vehicle body sheet metal, thereby playing a sealing role between the external environment and the driver's cabin. At this time, the dust cover and the sheet metal are generally in line contact, and the contact area is very small. Therefore, due to the objective reasons of manufacturing and assembly errors, the sealing effect is often poor. On the other hand, during dynamic driving of the vehicle, the vehicle bounces, which also causes the steering dust cover to deform and causes the sealing effect to be temporarily invalid. Therefore, how to further improve the sealing performance of the dust cover is a technical problem that needs to be solved today.

[0045] In view of this, in order to improve the sealing effect of the dust cover, the embodiments of the present application propose a steering dust cover for a vehicle, please refer to Figure 1 and Figure 2 , which comprises a dust cover body 100 and a first sealing member 200.

[0046] The dust cover body 100 defines a containing space 110 for containing the steering shaft. It can be understood that when the dust cover body 100 is assembled with the steering shaft, the steering shaft is contained through the containing space 110, and the steering shaft extends out of the opening of the vehicle body sheet metal 500. The dust cover is used to seal the opening of the vehicle body sheet metal 500 through which the steering shaft passes.

[0047] The dust cover body 100 has a first center line a, and the dust cover body 100 comprises a first mounting portion 120. In the first direction X, the first mounting portion 120 protrudes towards the first center line a to form a recessed portion 130 adapted to cooperate with the vehicle body sheet metal 500, and the first direction X is perpendicular to the first center line a. That is to say, the recessed portion 130 formed by the protrusion of the first mounting portion 120 towards the first center line a forms a physical clamping structure with the vehicle body sheet metal 500. In this way, not only is the installation and positioning facilitated, but also the contact area of the dust cover body 100 and the vehicle body sheet metal 500 is increased, which helps to reduce the displacement or looseness of the dust cover caused by vibration.

[0048] It can be understood that the recess 130 can also play a role in dispersing external impact force, which helps to reduce the probability of the dust cover being separated from the steering shaft during movement. Along the first center line a, the first mounting portion 120 can be multiple, and the multiple first mounting portions 120 are sequentially connected, and each first mounting portion 120 is provided with a recess 130. In the embodiment of the application, only one of the multiple first recesses 130 cooperates with the vehicle body sheet metal.

[0049] The dust cover body 100 can be configured as a rotary body, and the first center line a can be the rotary center line of the dust cover body 100. The dust cover body 100 can be made of an elastic member, for example, can be made of rubber material.

[0050] The first sealing member 200 is fixed to the first mounting portion 120 and located in the recess 130. The first sealing member 200 is configured as an elastic member to press against the vehicle body sheet metal 500 when the vehicle body sheet metal 500 cooperates with the recess 130. Since the first sealing member 200 is made of an elastic material, when the vehicle body sheet metal 500 cooperates with the recess 130, the first sealing member 200 is tightly attached to the surface of the vehicle body sheet metal 500 through elastic deformation, effectively filling the assembly gap and significantly improving the dustproof, waterproof and sound insulation effects.

[0051] During vehicle driving, the vehicle body can be micro-deformed due to vibration or temperature change. The first sealing member 200 made of elastic material can dynamically adjust the compression amount to maintain continuous sealing and avoid sealing failure caused by deformation.

[0052] It can be understood that when the first sealing member 200 is tightly attached to the surface of the vehicle body sheet metal 500 through elastic deformation, the vehicle body sheet metal 500 can also contact or even press against the dust cover body 100. Thus, the dustproof ability of the steering dust cover is further improved.

[0053] The steering dust cover provided in the embodiment of the application adds the first sealing member 200 on the basis of the traditional dust cover. Even if there is a small error in manufacturing and assembly, or the vehicle is bumpy during dynamic driving, the first sealing member 200 can still press against the vehicle body sheet metal 500, so that the contact area between the first sealing member 200 and the vehicle body sheet metal 500 is not too small, and the sealing effect is not lost, which effectively improves the dustproof, waterproof and sound insulation performance.

[0054] In other embodiments, please refer to Figure 2The first mounting portion 120 includes a first portion 121 and a second portion 122, and at least portions of the first portion 121 and the second portion 122 are spaced apart to form a recess 130 along a direction of the first center line a, that is, at least portions of the first portion 121 and at least portions of the second portion 122 are spaced apart to form a space capable of accommodating the first seal 200, which facilitates the accurate fitting of the vehicle body panel 500 to the recess 130 and facilitates the arrangement of the first seal 200.

[0055] It can be understood that when all of the first portion 121 and the second portion 122 are spaced apart, the cross-sectional shape of the recess 130 can be square, trapezoidal, etc., which is not limited in the present application.

[0056] When the first portion 121 and the second portion 122 are partially spaced apart, the cross section of the recess 130 can be V-shaped, U-shaped, etc., which is not limited in the present application.

[0057] The first seal 200 is arranged on the first portion 121, so that when the vehicle body panel 500 is fitted to the recess 130, the first seal 200 on the first portion 121 can better adhere to the vehicle body panel 500. Because the first portion 121 and the second portion 122 are spaced apart, the first seal 200 can have a more reasonable deformation space when being extruded, and can better adapt to the shape and position of the vehicle body panel 500, so as to maintain a better sealing pressure at each contact point and enhance the overall sealing performance, thereby more effectively blocking dust, water and noise.

[0058] In the above scheme, the first mounting portion 120 includes at least partially spaced first portion 121 and second portion 122, the first seal 200 is arranged on the first portion 121, at this time the vehicle body panel 500 is located in the space between the first portion 121 and the second portion 122, the first seal 200 plays a sealing role between the first portion 121 and the vehicle body panel 500, the first seal 200 tightly adheres to the surface of the vehicle body panel 500 through elastic deformation, effectively fills the assembly gap between the first portion 121 and the vehicle body panel 500, and significantly improves the dustproof, waterproof and sound insulation effect.

[0059] In other embodiments, please refer to Figure 2, along the first direction X, the distance between the first part 121 and the second part 122 in the extending direction of the first center line a gradually decreases. In this way, as the distance gradually decreases, the contact between the first sealing element 200 and the vehicle body panel 500 will be more closely when the vehicle body panel 500 is fitted into the recess 130. Because of this gradual structure, the first sealing element 200 can still be pressed against the vehicle body panel 500 when the distance between the dust cover body 100 and the vehicle body panel 500 changes at different positions, thereby better filling the possible gap and improving the integrity of the seal, effectively preventing dust, water and noise from entering.

[0060] In the above scheme, the distance between the first part 121 and the second part 122 in the extending direction of the first center line a gradually decreases, that is, the cross section of the recess 130 can be V-shaped, U-shaped, etc., which is not limited in the present application.

[0061] It can be understood that the dust cover body 100 will produce various vibrations and deformations during the driving of the vehicle. This gradually decreasing distance design makes the first sealing element 200 more flexible and adaptive to deformation when facing these situations. When the dust cover is vibrated or deformed due to vehicle movement, the first sealing element 200 can more reasonably adjust its deformation degree according to the changing trend of the distance between the first part 121 and the second part 122, for example, deforming more at a smaller distance, thereby having a larger contact surface with the vehicle body panel 500, always maintaining good sealing with the vehicle body panel 500 and ensuring that the sealing effect is not affected.

[0062] In other embodiments, please refer to Figure 2 The steering dust cover further comprises a second sealing element 300 fixed to the second part 122 and located in the recess 130, that is, two sealing elements are respectively arranged on the first part 121 and the second part 122, which can seal from both sides of the vehicle body panel 500 along its thickness direction, more comprehensively covering the contact area between the recess 130 and the vehicle body panel 500, and reducing the dead angle of the seal.

[0063] When the vehicle body panel 500 is fitted into the recess 130, the second sealing element 300 can fill the possible gap between the vehicle body panel 500 and the second part 122, ensuring that the entire contact circumference can achieve good sealing and effectively preventing external pollutants from entering the steering system.

[0064] In the above scheme, the first sealing element 200 and the second sealing element 300 form a double-sealing defense line. Even if the sealing performance of the first sealing element 200 decreases in some cases, such as slight wear after long-term use, local sealing pressure changes caused by vehicle bumping, etc., the second sealing element 300 can still continue to block the invasion of dust, water and noise, greatly improving the overall sealing reliability of the steering dust cover.

[0065] It can be understood that dust, water and noise usually appear at the same time, and the second seal 300 further enhances the sound insulation effect of the dust cover. The second seal 300 can work together with the first seal 200 to form a more effective sound insulation barrier, reduce the external noise entering the vehicle through the gap between the vehicle body panel 500 and the dust cover, and create a quieter driving environment for the passengers in the vehicle.

[0066] As an example, the first seal 200 and the second seal 300 are not directly opposite in the extension direction of the first center line a, that is, when the first seal 200 and the second seal 300 are respectively configured as sealing rings, the annular diameters surrounded by the first seal 200 and the second seal 300 are different. In this way, the first seal 200 and the second seal 300 can respectively improve the sealing effect under different amplitude vibrations.

[0067] As an example, the first seal 200 and the second seal 300 are oppositely arranged along the extension direction of the first center line a, that is, along the extension direction of the first center line a, the same position of the vehicle body panel 500 on the thickness direction is simultaneously sealed by the first seal 200 and the second seal 300.

[0068] In this way, when external dust, moisture, oil stains and other impurities attempt to invade, the first seal 200 can first block a part of the impurities, and the remaining impurities that are not completely blocked will be further blocked by the second seal 300 when reaching the second seal 300, thereby greatly improving the reliability of the seal and effectively preventing impurities from entering the internal space that needs to be sealed.

[0069] As an example, the second seal 300 has a third cavity inside, and the second seal 300 is provided with a third exhaust hole, and the third exhaust hole communicates the third cavity and the outside. In this way, the deformation degree of the second seal 300 can be improved, and the contact area between the second seal 300 and the vehicle body panel 500 is further increased, thereby further improving the sealing effect of the second seal 300 on the vehicle body panel 500 and the second part 122.

[0070] In other embodiments, please refer to Figure 3The first sealing member 200 has a first cavity 210 inside, and the first sealing member 200 is provided with a first exhaust hole 220, which communicates the first cavity 210 with the outside, that is, the volume of the first cavity 210 inside the first sealing member 200 can be reduced as the gas is exhausted from the first exhaust hole 220. In this way, the deformation degree of the first sealing member 200 can be improved, and the contact area between the first sealing member 200 and the vehicle body panel 500 can be further increased, thereby further improving the sealing effect of the first sealing member 200 on the vehicle body panel 500 and the first part 121. Of course, when the pressure acting on the first sealing member 200 decreases, the air from the outside can enter the first cavity 210 from the first exhaust hole 220, so that the shape of the first sealing member 200 can be restored.

[0071] It can be understood that if the first sealing member 200 does not have the first cavity 210 and the first exhaust hole 220 inside, stress concentration may occur inside the sealing member when it is subjected to pressure changes and vibrations, causing local wear or damage to intensify. The design of the first cavity 210 and the first exhaust hole 220 can evenly distribute the pressure and reduce stress concentration, thereby reducing the risk of fatigue cracks, ruptures and other damage to the first sealing member 200, and prolonging its service life.

[0072] As an example, the first exhaust hole 220 can be multiple, and the multiple first exhaust holes 220 are arranged at intervals along the extension direction of the first sealing member 200, that is, the multiple first exhaust holes 220 can communicate the first cavity 210 with the outside at different positions of the first sealing member 200. The multiple spaced exhaust holes enable the sealing member to timely adjust the pressure at different positions according to the deformation.

[0073] During vehicle operation, the steering dust cover will produce complex local deformation due to various factors, that is, when a certain area of the first sealing member 200 is extruded or the vehicle is jolted in different directions, the exhaust hole in the corresponding area can quickly exhaust or inhale air, allowing the area to quickly deform and maintain adhesion with the vehicle body panel 500, thereby improving the sealing effect.

[0074] It can be understood that when the vehicle is steering or performing other operations, the steering dust cover may be twisted or deformed to some extent, which will cause the air inside the first sealing member 200 to be extruded and then exhausted from the first exhaust hole 220, thereby increasing the deformation degree of the first sealing member 200 and expanding the contact area between the first sealing member 200 and the vehicle body panel 500. If there is no exhaust hole, the air cannot be exhausted or entered, and the internal pressure will be accumulated, affecting the performance of the sealing member.

[0075] In addition, during the driving of the vehicle, the external environment pressure changes with factors such as altitude and speed, and the vibration and movement of the vehicle itself also cause fluctuations in the air pressure inside the dust cover. The first cavity 210 and the first exhaust hole 220 are arranged to enable the air inside the first sealing member 200 to communicate with the external air, thereby quickly balancing the internal and external pressures. This prevents the first sealing member 200 from deforming, being damaged, or having a reduced sealing performance due to an excessively large pressure difference, and ensures that the first sealing member 200 can normally work in various working conditions.

[0076] In some other embodiments, referring to Figure 1 and Figure 2 , the first sealing member 200 is configured as a first sealing ring surrounding the first center line a, that is, the first sealing ring is arranged in a head-to-tail manner around the first center line a, and can form a continuous and complete sealing structure around the steering shaft, thereby sealing the gap between the steering shaft and the vehicle body panel 500 in all directions. In this way, the sealing effect can be further improved by effectively preventing dust, water, and noise from entering the steering system from all directions.

[0077] In the above scheme, the annular structure of the sealing ring enables it to uniformly apply sealing pressure in the entire circumferential direction when it is pressed by the vehicle body panel 500, which ensures that the contact between the first sealing member 200 and the vehicle body panel 500 is more closely and the sealing effect is more stable, thereby avoiding the occurrence of local sealing failure due to uneven pressure.

[0078] As an example, the first sealing member 200 can also be configured as a sealing strip, a sealing block, or the like, which is not limited in the present application.

[0079] As an example, the cross-sectional shape of the first sealing member 200 can be semicircular, semi-elliptical, or the like, as long as it can play a special sealing role, which is not limited in the present application.

[0080] In some other embodiments, referring to Figure 3 , the steering dust cover further comprises a third sealing member 400 fixed to the first mounting portion 120 and located in the recessed portion 130, and the third sealing member 400 is arranged at least partially spaced apart from the first sealing member 200 in the extension direction of the first center line a, so as to clamp the vehicle body panel 500 when the vehicle body panel 500 is fitted into the recessed portion 130.

[0081] In the above scheme, the first seal 200 and the third seal 400 are at least partially spaced apart along the extension direction of the first center line a. It can be understood that when the first seal 200 and the third seal 400 are only partially spaced apart along the extension direction of the first center line a, and the first seal 200 and the third seal 400 are respectively configured as sealing rings, the annular diameters surrounded by the first seal 200 and the third seal 400 are different. In this way, the first seal 200 and the third seal 400 can respectively improve the sealing effect under different amplitude vibrations.

[0082] As an example, when the first seal 200 and the third seal 400 are spaced apart along the extension direction of the first center line a, that is, along the extension direction of the first center line a, the two sides of the body sheet metal 500 along the thickness direction are simultaneously sealed by the first seal 200 and the third seal 400.

[0083] In this way, when foreign matter such as dust, moisture, and oil stains from the outside attempts to intrude, the first seal 200 can first block a part of the foreign matter, and the remaining foreign matter that is not completely blocked will be further blocked by the third seal 400 when reaching the third seal 400, thereby greatly improving the reliability of the seal and effectively preventing the foreign matter from entering the internal space that needs to be sealed.

[0084] In other embodiments, please refer to Figure 3 The third seal 400 has a second cavity 410 inside, and the third seal 400 is provided with a second exhaust hole 420, and the second exhaust hole 420 communicates the second cavity 410 with the outside, that is, the volume of the second cavity 410 inside the third seal 400 can become smaller as the gas is exhausted from the second exhaust hole 420. In this way, the deformation degree of the third seal 400 can be improved, and the contact area between the third seal 400 and the body sheet metal 500 is further increased, thereby further improving the sealing effect of the third seal 400 on the body sheet metal 500 and the recess 130. Of course, when the pressure acting on the third seal 400 decreases, the air from the outside can enter the second cavity 410 from the second exhaust hole 420, so that the shape of the third seal 400 is restored.

[0085] It can be understood that if the third seal 400 does not have the second cavity 410 and the second exhaust hole 420 inside, stress concentration may occur inside the seal when subjected to pressure changes and vibrations, causing local wear or damage to intensify. The design of the second cavity 410 and the second exhaust hole 420 can make the pressure uniformly distributed, reduce stress concentration, thereby reducing the risk of fatigue cracks, rupture, and other damage of the third seal 400, and prolonging its service life.

[0086] As an example, the second exhaust hole 420 can be multiple, multiple second exhaust holes 420 are arranged along the extension direction of the third sealing piece 400, that is, multiple second exhaust holes 420 can communicate the second cavity 410 with the outside at different positions of the third sealing piece 400, and multiple spaced second exhaust holes 420 enable timely pressure regulation of different positions of the third sealing piece 400 according to deformation.

[0087] During vehicle operation, the steering dust cover will produce complex local deformation due to various factors, that is, when a certain area of the third sealing piece 400 is extruded or the vehicle bounces in different directions, the exhaust hole of the corresponding area can quickly exhaust or inhale air, allowing the area to deform quickly and adhere to the vehicle body panel 500, thereby improving the sealing effect.

[0088] It can be understood that when the vehicle is steering or performing other operations, the steering dust cover may be twisted or deformed to a certain extent, which will cause the air inside the third sealing piece 400 to be extruded and then discharged from the second exhaust hole 420, thereby increasing the deformation degree of the third sealing piece 400 and expanding the contact area between the third sealing piece 400 and the vehicle body panel 500. If there is no exhaust hole, air cannot be discharged or entered, and internal pressure will accumulate, affecting the performance of the sealing piece.

[0089] In addition, during vehicle operation, the external environment pressure will change with factors such as altitude and speed, and the vibration and movement of the vehicle itself will also cause fluctuations in the air pressure inside the dust cover. The arrangement of the second cavity 410 and the second exhaust hole 420 enables the air inside the third sealing piece 400 to be in communication with the outside air, thereby quickly balancing the internal and external pressures. This can prevent the third sealing piece 400 from deforming, being damaged, or having a reduced sealing performance due to excessive pressure difference, and ensures that it can work normally under various working conditions.

[0090] In other embodiments, the third sealing piece 400 is configured as a third sealing ring around the first center line a, that is, the third sealing ring is arranged in a continuous and complete sealing structure around the first center line a, which can realize omnidirectional sealing of the gap between the steering shaft and the vehicle body panel 500. In this way, the arrangement can effectively prevent dust, water, and noise from entering the steering system from all directions, further improving the sealing effect.

[0091] In the above scheme, the annular structure of the sealing ring enables it to uniformly apply sealing pressure in the entire circumferential direction when it is extruded by the vehicle body panel 500, which can ensure that the contact between the third sealing piece 400 and the vehicle body panel 500 is more close and the sealing effect is more stable, avoiding the occurrence of local sealing failure due to uneven pressure.

[0092] As an example, the third sealing member 400 can also be configured as a sealing strip, a sealing block, etc., which is not limited in the application.

[0093] As an example, the cross-sectional shape of the third sealing member 400 can be semicircular, semi-elliptical, etc., or other shapes, as long as it can play a special sealing role, which is not limited in the application.

[0094] As an example, at least one of the dust cover body 100, the first sealing member 200, the second sealing member 300, and the fourth sealing member 400 can be made of a rubber material, including but not limited to thermoplastic vulcanized rubber, ethylene propylene diene rubber, butadiene-acrylonitrile rubber, silicone rubber, chloroprene rubber, and polyurethane rubber, which is not limited in the application.

[0095] In addition, at least one of the dust cover body 100, the first sealing member 200, the second sealing member 300, and the fourth sealing member 400 can also be made of an elastic material such as polyether ether ketone, thermoplastic elastomer, and thermoplastic polyurethane elastomer, which is not limited in the application.

[0096] In specific embodiments, the structure of the second sealing member 300 and the structure of the third sealing member 400 can be the same, and the setting position of the second sealing member 300 can be the same as the setting position of the third sealing member 400, that is, to realize the combination of various embodiments without conflict, which is not limited in the application.

[0097] For example, the second sealing member 300 can also have a cavity inside and an exhaust hole for connecting the cavity with the outside; the number of exhaust holes can also be multiple, and the arrangement manner is the same as that of the multiple second exhaust holes 420; the second sealing member 300 can also be configured as a sealing ring.

[0099] The vehicle provided in the embodiments of the application has the dust cover in the above embodiments, thereby improving the sealing effect of the vehicle.
