Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and in particular to a chassis protection plate structure and vehicle. Background Technology

[0002] When a vehicle is traveling at high speeds, air resistance can account for more than 80% of the total drag experienced by the vehicle. Therefore, reducing air resistance is crucial for improving fuel economy and driving range. Of this, 25% of air resistance is caused by airflow changes resulting from the wheels and wheel arches, making it essential to reduce air resistance around the vehicle.

[0003] Currently, adding air dams is commonly used to reduce the direct airflow impacting the front wheels, thereby reducing the interaction between the airflow and the front wheels and lowering vehicle air resistance. However, the installation of air dams reduces the amount of air entering the wheel cavity where the front wheels are mounted, which in turn affects the heat dissipation rate of the braking system at the front wheels, increasing the probability of brake disc failure and reducing vehicle safety performance. Utility Model Content

[0004] To address or partially address the aforementioned problems, this application discloses a bottom guard plate structure and vehicle, aiming to solve the problem in the prior art where the setting of air dams affects the heat dissipation rate of the braking system at the front wheels, increases the probability of brake disc failure in the braking system, and reduces the safety performance of the vehicle.

[0005] Firstly, to address the aforementioned problems, embodiments of this application provide a bottom guard structure for protecting the front wheels of a vehicle, the bottom guard structure comprising:

[0006] The bottom guard plate body and the protective frame body are provided. The protective frame body is installed on the periphery of the front wheel and located in the wheel cavity formed by the installation position of the front wheel. The bottom guard plate body is connected to the protective frame body on the side away from the front wheel and extends in the direction away from the front wheel.

[0007] An air dam is connected to the bottom protective plate body. The air dam includes a windproof structure that protrudes from the bottom protective plate body and extends away from the protective frame body.

[0008] A flow guiding structure is installed on a first surface of the underbody, and the flow guiding structure forms at least one flow guiding channel. The flow guiding channel is connected to the wheel cavity formed by the mounting position of the front wheel. The first surface is the surface of the underbody and the surface on which the windshield structure is installed are in a relative position.

[0009] Because the air dam is connected to the underbody protection plate, and includes a windbreak structure that protrudes from the underbody protection plate and extends away from the main body of the protective frame, it can block air from entering the front wheel area, thereby reducing the direct impact of airflow on the front wheel and reducing the interaction between the airflow and the front wheel, thus reducing the vehicle's air resistance. Furthermore, because the airflow guide structure is installed on the first surface of the underbody protection plate, forming at least one airflow channel, this channel communicates with the wheel cavity formed by the front wheel mounting position. The first surface is the surface of the underbody protection plate that is in a relative position to the surface where the windbreak structure is installed. Therefore, the air from the front wheel area can be guided into the wheel cavity formed by the airflow channel, allowing the brake discs of the braking system installed in the wheel cavity to be cooled. In summary, in this embodiment, not only can the windbreak structure block air from entering the front wheel, thereby reducing the direct impact of airflow on the front wheel and reducing the interaction between the airflow and the front wheel to reduce vehicle air resistance, but the airflow channel formed by the guide structure can also guide the air in front of the front wheel into the wheel cavity formed at the installation position of the front wheel, thereby increasing the heat dissipation rate of the braking system at the front wheel, reducing the probability of brake disc failure, and improving vehicle safety performance.

[0010] In some embodiments, the flow guiding structure is a protruding structure protruding from the bottom protective plate body, and the top surface of the protruding structure is a first curved surface structure, which forms the flow guiding channel.

[0011] In this way, since the airflow guiding structure is a protruding structure that protrudes from the bottom guard plate body, and the top surface of the protruding structure is a first curved surface structure, the first curved surface structure forms an airflow guiding channel. Therefore, a path can be formed at the first curved surface structure to guide the airflow to the wheel cavity formed at the installation position of the front wheel, which facilitates the flow of airflow.

[0012] In some embodiments, the flow guiding structure includes a plurality of the protruding structures, which are arranged at equal intervals.

[0013] In this way, since the airflow guiding structure includes multiple protruding structures, and the multiple protruding structures are equally spaced, the multiple first curved surface structures formed by the multiple airflow guiding structures can jointly guide the airflow to the wheel cavity formed at the installation position of the front wheel, thereby improving the path of the airflow into the wheel cavity formed at the installation position of the front wheel, further improving the heat dissipation rate of the braking system at the front wheel, and reducing the probability of brake disc failure in the braking system.

[0014] In some embodiments, the protruding structure extends from one end of the bottom guard plate body away from the protective frame body to the connection position between the bottom guard plate body and the protective frame body.

[0015] In this way, since the protruding structure extends from the end of the bottom guard plate away from the main body of the protective frame to the connection position between the bottom guard plate and the main body of the protective frame, the airflow can be introduced from the end of the bottom guard plate away from the main body of the protective frame to the connection position between the bottom guard plate and the main body of the protective frame through the protruding structure. Then, under the obstruction of the main body of the protective frame, it enters the wheel cavity formed by the installation position of the front wheel from the side of the main body of the protective frame, thereby ensuring the continuity of the airflow guiding channel and ensuring the normal introduction of airflow.

[0016] In some embodiments, the first curved surface structure is concave to the first surface.

[0017] This allows the airflow to gradually diffuse towards the upper part of the protective frame body as it passes over the first curved surface, which is more conducive to ensuring that the airflow enters the wheel cavity formed at the installation position of the front wheel.

[0018] In some embodiments, the air dam is installed at the connection between the bottom protective plate body and the protective frame body.

[0019] This allows the air dam, the bottom protective plate, and the main body of the protective frame to form a single integrated structure, facilitating the assembly and installation of the air dam.

[0020] In some embodiments, the bottom protective plate structure further includes a snap-fit ​​structure;

[0021] The air dam also includes a connecting plate, which is connected to the windbreak structure. The connection between the bottom guard plate body and the main body of the protective frame is provided with an installation slot. The windbreak structure extends through the installation slot in a direction away from the main body of the protective frame. The bottom guard plate body is snapped into the edge of the slot by the snap-fit ​​structure.

[0022] In this way, since the bottom guard plate structure also includes a snap-fit ​​structure, the air dam can be detachably connected to the connection between the bottom guard plate body and the main body of the protective frame through the snap-fit ​​structure. Therefore, a detachable connection between the air dam and the main body of the bottom guard plate can be achieved, so that the air dam can be replaced in a timely manner when it is damaged or its size is not suitable for blocking the airflow.

[0023] In some embodiments, the windshield structure is a shell structure, and the surface of the windshield structure away from the front wheel is a second curved surface structure, the second curved surface structure being convex in the direction away from the front wheel.

[0024] In this way, since the windshield structure is a shell structure, the surface of the windshield structure away from the front wheel is a second curved surface structure. The second curved surface structure convexes in the direction away from the front wheel, which can reduce the overall shape drag of the windshield structure. At the same time, it can reduce the interaction between airflow and wheels, and reduce the overall wind resistance of the vehicle.

[0025] In some embodiments, the windbreak structure is movably connected to the connection between the bottom guard plate body and the protective frame body, so that the included angle between the second curved surface structure and the first surface is adjustable.

[0026] In this way, the windshield angle of the windshield structure can be adjusted by adjusting the included angle between the second curved surface structure and the first surface, which makes it easier to adjust the overall shape resistance of the windshield structure, so as to further ensure the effect of the windshield structure in reducing the air resistance of the vehicle.

[0027] Secondly, embodiments of this application also provide a vehicle, the vehicle including the underbody protection structure described in any of the embodiments in the first direction.

[0028] Thus, when the vehicle includes the underbody protection structure described in any of the embodiments of the first aspect, the vehicle can not only block the air in front of the front wheels from entering the front wheels through the windshield structure, thereby reducing the airflow that directly impacts the front wheels and reducing the interaction between the airflow and the front wheels, thereby reducing the vehicle's air resistance, but also guide the air in front of the front wheels into the wheel cavity formed by the guide structure through the guide channel, thereby increasing the heat dissipation rate of the braking system at the front wheels, reducing the probability of brake disc failure in the braking system, and improving the vehicle's safety performance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Please refer to Figures 1 to 4 This application provides a chassis guard structure for protecting the front wheels of a vehicle. The chassis guard structure includes:

[0040] The underbody plate body 1 and the protective frame body 2 are installed on the periphery of the front wheel and located in the wheel cavity formed by the installation position of the front wheel. The underbody plate body 1 is connected to the side of the protective frame body 2 away from the front wheel and extends in the direction away from the front wheel.

[0041] Air dam 3 is connected to the bottom protective plate body 1. Air dam 3 includes a windproof structure 31, which protrudes from the bottom protective plate body 1 and extends in a direction away from the protective frame body 2.

[0042] The flow guiding structure 4 is installed on the first surface of the bottom guard plate body 1. The flow guiding structure 4 forms at least one flow guiding channel, which is connected to the wheel cavity formed by the installation position of the front wheel. The first surface is the surface of the bottom guard plate body 1 that is in a relative position to the surface on which the windshield structure 31 is installed.

[0043] In this embodiment, since the air dam 3 is connected to the underbody body 1, and the air dam 3 includes a windbreak structure 31 that protrudes from the underbody body 1 and extends away from the protective frame body 2, the windbreak structure 31 can block air from entering the front wheel, thereby reducing the airflow that directly impacts the front wheel and reducing the interaction between the airflow and the front wheel, thus reducing the vehicle's air resistance. Furthermore, since the guide structure 4 is installed on the first surface of the underbody body 1, and the guide structure 4 forms at least one guide channel, which communicates with the wheel cavity formed by the front wheel mounting position, the first surface is the surface of the underbody body 1 where the surface where the windbreak structure 31 is installed is in a relative position. Therefore, the guide channel formed by the guide structure 4 can guide air from the front wheel into the wheel cavity formed by the front wheel mounting position, allowing the brake disc of the braking system installed in the wheel cavity to be cooled. In summary, in this embodiment, not only can the windbreak structure 31 block air from entering the front wheel, thereby reducing the direct impact of airflow on the front wheel and reducing the interaction between the airflow and the front wheel to reduce vehicle air resistance, but the airflow channel formed by the guide structure 4 can also guide the air in front of the front wheel into the wheel cavity formed at the installation position of the front wheel, thereby increasing the heat dissipation rate of the braking system at the front wheel, reducing the probability of brake disc failure in the braking system, and improving the vehicle's safety performance.

[0044] In the above embodiments, the underbody plate body 1 is a plate-shaped structure. To improve the strength of the underbody plate body 1, a rib structure, a reinforcing groove structure, or other structures that can improve strength can be provided on the underbody plate body 1. This application embodiment does not limit this. The underbody plate body 1 can be installed on the front protective sheet metal, fender sheet metal, and other underbody plates. The protective frame body 2 is a frame-shaped structure that can form a certain cavity structure to form a cavity that can accommodate the front wheel, so that the protective frame body 2 is installed on the periphery of the front wheel and located at the wheel cavity formed by the installation position of the front wheel. The underbody plate body 1 is located on the side of the protective frame body 2 away from the wheel and extends in the direction away from the front wheel, that is, it extends in the direction from the rear of the vehicle towards the front.

[0045] The air dam 3 can be detachably connected to the underbody plate body 1 via a snap-fit ​​structure, bolt structure, rivet structure, or welding method. This application embodiment does not limit the connection. The air dam 3 can be any of the following: shell structure, plate structure, or frame structure. The air dam 3 has at least one windproof structure 31 protruding from the underbody plate body 1, and the windproof structure 31 extends away from the protective frame body 2, so that the windproof structure 31 extends in a direction perpendicular to the ground. This allows the windproof structure 31 to block air from entering the front wheel and reduce the airflow that directly impacts the front wheel.

[0046] The airflow guiding structure 4 can be one or more structures that guide airflow through. The airflow guiding structure 4 is set on the first surface of the bottom guard plate body 1 and can form an airflow guiding channel to guide airflow into the wheel cavity formed by the installation position of the front wheel. In turn, the air in front of the front wheel can be guided into the wheel cavity formed by the airflow guiding structure 4 through the airflow guiding channel formed by the airflow guiding structure 4.

[0047] Regarding the specific structure of the flow guiding structure 4, in some embodiments, the flow guiding structure 4 is a protruding structure that protrudes from the bottom protective plate body 1, and the top surface of the protruding structure is a first curved surface structure 41, which forms a flow guiding channel.

[0048] In this embodiment, since the flow guiding structure 4 is a protruding structure protruding from the bottom guard plate body 1, and the top surface of the protruding structure is a first curved surface structure 41, the first curved surface structure 41 forms a flow guiding channel. Therefore, a path can be formed at the first curved surface structure 41 to guide the airflow to the wheel cavity formed at the installation position of the front wheel, which facilitates the flow of airflow.

[0049] In some embodiments, the flow guiding structure 4 includes a plurality of protrusions, which are arranged at equal intervals.

[0050] In this embodiment, since the flow guiding structure 4 includes multiple protruding structures and the multiple protruding structures are equally spaced, the multiple first curved surface structures 41 formed by the multiple flow guiding structures 4 can jointly guide the airflow to the wheel cavity formed at the installation position of the front wheel, thereby improving the path of the airflow into the wheel cavity formed at the installation position of the front wheel, further improving the heat dissipation rate of the braking system at the front wheel, and reducing the probability of brake disc failure in the braking system.

[0051] In some embodiments, the protruding structure extends from the end of the bottom guard plate body 1 away from the protective frame body 2 to the connection position between the bottom guard plate body 1 and the protective frame body 2.

[0052] In this embodiment, since the protruding structure extends from the end of the bottom guard plate body 1 away from the protective frame body 2 to the connection position between the bottom guard plate body 1 and the protective frame body 2, the airflow can be introduced from the end of the bottom guard plate body 1 away from the protective frame body 2 to the connection position between the bottom guard plate body 1 and the protective frame body 2 through the protruding structure. Then, under the obstruction of the protective frame body 2, it enters the wheel cavity formed by the installation position of the front wheel from the side of the protective frame body 2, thereby ensuring the continuity of the airflow guiding channel and ensuring the normal introduction of airflow.

[0053] It should be noted that the protruding structure can be any shape, such as a strip-shaped protrusion, a triangular block-shaped structure, or a crescent-shaped plate-shaped structure; this embodiment of the application does not limit this. Thus, the protruding structure not only guides airflow to the wheel cavity formed at the mounting position of the front wheel, but also forms the rib structure of the bottom guard plate body 1, thereby improving the overall strength of the bottom guard plate body 1.

[0054] In some embodiments, the first curved surface structure 41 is concave to the first surface.

[0055] In this embodiment, since the first curved surface structure 41 is concave to the first surface, the airflow can gradually diffuse towards the upper part of the protective frame body 2 through the first curved surface structure 41 when passing through the first curved surface, which is more conducive to ensuring that the airflow enters the wheel cavity formed at the installation position of the front wheel.

[0056] In some embodiments, the air dam 3 is installed at the connection between the bottom protective plate body 1 and the protective frame body 2.

[0057] In this embodiment, since the air dam 3 is installed at the connection between the bottom protective plate body 1 and the protective frame body 2, the air dam 3, the bottom protective plate body 1 and the protective frame body 2 can form an integral structure, which facilitates the assembly and installation of the air dam 3.

[0058] In some embodiments, the bottom guard plate structure further includes a snap-fit ​​structure 5, through which the air dam 3 is detachably connected to the connection between the bottom guard plate body 1 and the protective frame body 2 via the snap-fit ​​structure 5.

[0059] In this embodiment, since the bottom guard plate structure also includes a snap-fit ​​structure 5, the air dam 3 is detachably connected to the connection between the bottom guard plate body 1 and the protective frame body 2 through the snap-fit ​​structure 5. Therefore, a detachable connection between the air dam 3 and the bottom guard plate body can be achieved, so that when the air dam 3 is damaged or the size of the air dam 3 is not suitable for blocking the airflow, it is convenient to replace the air dam 3 in a timely manner.

[0060] Specifically, in some embodiments, the air dam 3 further includes a connecting plate 32, which is connected to the windbreak structure 31. An installation slot is provided at the connection point between the bottom protective plate body 1 and the protective frame body 2. The windbreak structure 31 extends through the installation slot in a direction away from the protective frame body 2. The bottom protective plate body 1 is snapped into place at the edge of the installation slot by a snap-fit ​​structure 5. This facilitates a detachable connection between the air dam 3 and the bottom protective plate body without adding other connecting structures, and without increasing the overall structural dimensions of the bottom protective plate body or the protective frame body 2.

[0061] In some embodiments, the windshield structure 31 is a shell structure, and the surface of the windshield structure 31 away from the front wheel is a second curved surface structure 311, which convexes in the direction away from the front wheel.

[0062] In this embodiment, since the windshield structure 31 is a shell structure, the surface of the windshield structure 31 away from the front wheel is a second curved surface structure 311. The second curved surface structure 311 protrudes in the direction away from the front wheel, thus reducing the overall shape drag of the windshield structure 31 and reducing the interaction between airflow and wheels, thereby reducing the overall vehicle wind resistance.

[0063] In some embodiments, the windbreak structure 31 is movably connected to the connection between the bottom guard plate body 1 and the protective frame body 2, so that the included angle between the second curved surface structure 311 and the first surface is adjustable.

[0064] In this embodiment, since the windshield structure 31 is movably connected to the connection between the bottom guard plate body 1 and the protective frame body 2, the included angle between the second curved surface structure 311 and the first surface is adjustable. Therefore, by adjusting the included angle between the second curved surface structure 311 and the first surface, the windshield angle of the windshield structure 31 can be adjusted, which facilitates the adjustment of the overall shape resistance of the windshield structure 31, so as to further ensure the effect of the windshield structure 31 in reducing the air resistance of the vehicle.

[0065] It should be noted that the movable connection between the windbreak structure 31, the bottom guard plate body 1, and the protective frame body 2 can be achieved through gear rotation, shaft rotation, sliding connection, etc., and this application embodiment does not limit this. For example, taking the method of hinged connection between the windbreak structure 31, the bottom guard plate body 1, and the protective frame body 2 through shaft rotation as an example, a first hinge hole can be opened on the windbreak structure 31, and a second hinge hole can be provided at the connection between the bottom guard plate body 1 and the protective frame body 2. The shaft passes through both the first and second hinge holes, so that the windbreak structure 31 can rotate, and thus the included angle between the second curved surface structure 311 and the first surface can be changed as the windbreak structure 31 rotates.

[0066] As can be seen from the above embodiments, in this embodiment, since the air dam 3 is connected to the underbody 1, and the air dam 3 includes a windbreak structure 31 that protrudes from the underbody 1 and extends away from the protective frame body 2, the windbreak structure 31 can block air from entering the front wheel, thereby reducing the airflow that directly impacts the front wheel and reducing the interaction between the airflow and the front wheel, thus reducing the vehicle's air resistance. Furthermore, since the guide structure 4 is installed on the first surface of the underbody 1, and the guide structure 4 forms at least one guide channel, which is connected to the wheel cavity formed by the front wheel mounting position, the first surface is the surface of the underbody 1 where the surface where the windbreak structure 31 is installed is in a relative position. Therefore, the guide channel formed by the guide structure 4 can guide the air from the front wheel into the wheel cavity formed by the front wheel mounting position, allowing the brake disc of the braking system installed in the wheel cavity to be cooled. In summary, in this embodiment, not only can the windbreak structure 31 block air from entering the front wheel, thereby reducing the direct impact of airflow on the front wheel and reducing the interaction between the airflow and the front wheel to reduce vehicle air resistance, but the airflow channel formed by the guide structure 4 can also guide the air in front of the front wheel into the wheel cavity formed at the installation position of the front wheel, thereby increasing the heat dissipation rate of the braking system at the front wheel, reducing the probability of brake disc failure in the braking system, and improving the vehicle's safety performance.

[0067] In some embodiments, this application also provides a vehicle that includes the underbody protection structure described in any of the above embodiments.

[0068] It should be noted that when the vehicle includes the underbody protection structure described in any of the above embodiments, the vehicle can not only block the air in front of the front wheel from entering the front wheel through the windshield structure 31, thereby reducing the airflow that directly impacts the front wheel and reducing the interaction between the airflow and the front wheel to reduce the vehicle's air resistance, but also guide the air in front of the front wheel into the wheel cavity formed by the guide channel formed by the guide structure 4, thereby increasing the heat dissipation rate of the braking system at the front wheel, reducing the probability of brake disc failure in the braking system, and improving the vehicle's safety performance.
