Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle chassis technology, and in particular to a vehicle chassis protection assembly and a vehicle. Background Technology
[0002] Due to the complex driving environment of vehicles, when the road surface is uneven or contains a lot of mud, sand, stones and other impurities, these impurities will splash and impact the vehicle chassis and other components on it, thereby affecting the service life of the vehicle chassis.
[0003] Therefore, protective plates are usually installed on the chassis of vehicles to provide protection. Traditional protective plates are flat structures. Although they can prevent impurities from directly colliding with the chassis, their installation and positioning are relatively complicated, requiring a long assembly time and resulting in low efficiency. If not installed properly, the protective plate will rub or collide with the chassis during vehicle operation, causing abnormal noises and affecting the driving and riding experience, thus having certain limitations. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a vehicle chassis protection assembly and a vehicle, which can effectively protect the vehicle chassis, reduce air resistance during vehicle operation, help improve the vehicle's driving range, and simplify positioning and assembly, thereby improving assembly efficiency.
[0005] This utility model provides a vehicle chassis protection assembly, including a plate body. The lower end of the plate body is provided with an air guide groove, which is configured to extend in the front-rear direction and / or is configured to include an arc segment, which arches in the left-right direction. The front end of the plate body is provided with a positioning member, which can cooperate with the positioning groove on the leg anti-collision bracket in the front-rear direction.
[0006] In one embodiment, the front end of the air guide channel is provided with a guide ramp, the height of which relative to the ground is configured to increase from front to back.
[0007] In one embodiment, a groove is provided at the lower end of the plate, and an installation hole is provided in the groove. An installation component is installed in the installation hole, and the installation component is used to fix the plate to the vehicle chassis.
[0008] In one embodiment, the settling trough is partially or completely contained within the air guide trough, and the height of the bottom of the settling trough relative to the ground is configured to be greater than or equal to the height of the bottom of the air guide trough relative to the ground.
[0009] In one embodiment, a second protrusion is provided at the upper front end of the plate body at a position corresponding to the sink groove. The mounting hole passes through the second protrusion, and the upper end of the second protrusion is used to contact the lower end of the leg anti-collision bracket. The mounting hole engages with a mating hole opened on the leg anti-collision bracket.
[0010] In one embodiment, the front end of the plate is provided with a first limiting member and a second limiting member. The first limiting member extends in the front-back direction, and the second limiting member extends in the up-down direction. The upper end of the second limiting member is connected to the first limiting member, and the lower end is connected to the plate. The first limiting member cooperates with the limiting groove on the leg anti-collision bracket in the up-down direction.
[0011] In one embodiment, the plate has flanges at both ends, and the height of the flanges relative to the ground is configured to be greater than the height of the plate relative to the ground. The flanges cooperate with the plate to form air guide grooves at both ends of the plate.
[0012] In one embodiment, a leg impact protection bracket is also included. The leg impact protection bracket is located at the upper front end of the plate body. The rear end of the leg impact protection bracket is provided with the positioning groove. The positioning groove is connected to the positioning member.

[0013] In one embodiment, a limiting groove is provided at the lower end of the leg anti-collision bracket, and the limiting groove cooperates with a first limiting member at the front end of the plate body, the limiting groove being used to accommodate the first limiting member.
[0014] This utility model also proposes a vehicle including the aforementioned vehicle chassis protection assembly.
[0015] The beneficial effects of this utility model are as follows:
[0016] The panel protects the vehicle chassis, effectively preventing road debris such as stones and mud from directly contacting the chassis and its components, thus extending the chassis's lifespan. The air duct guides airflow under the vehicle; when the duct includes an arc section, this section effectively guides airflow during cornering, reducing wind resistance, improving aerodynamics, and ultimately extending the vehicle's range. The positioning components allow for quick and precise alignment of the panel with the leg impact brace in the front-rear direction, ensuring accurate positioning relative to the chassis. This reduces assembly difficulty and time costs for workers, facilitating panel assembly and disassembly. The simple structure enhances ease of operation. Attached Figure Description

[0028] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0029] Unless otherwise explicitly specified and limited, the terms "setup," "installation," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms based on the specific circumstances.
[0030] The terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.
[0032] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.
[0033] To facilitate understanding of the positional, connection, or relative motion relationships of the components in this utility model, the following orientations are based on the vehicle's coordinate system. The vehicle coordinate system is a special moving coordinate system used to describe the motion of a car. The origin of this coordinate system coincides with the center of mass of the vehicle. When the vehicle is stationary on a horizontal road, the X-axis of this coordinate system refers to the direction parallel to the direction of the car's travel, i.e., the front-to-back direction; the Y-axis refers to the width direction of the car, i.e., the left-to-right direction; and the Z-axis refers to the height direction of the car, i.e., the up-and-down direction.
[0034] Figure 1 This is a schematic diagram of the lower surface of the plate 10 according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the lower surface of the plate 10 and the leg anti-collision bracket 20 in one embodiment of the present invention.
[0035] Combination Figure 1 , Figure 4 and Figure 5The vehicle chassis protection assembly proposed in this utility model includes a plate 10, with an air guide 11 at the lower end of the plate 10. The air guide 11 is configured to extend in the front-rear direction, and / or the air guide 11 is configured to include an arc segment 111, which arches in the left-right direction. A positioning member 12 is protruding at the front end of the plate 10. The positioning member 12 is connected to the positioning groove 21 on the leg anti-collision bracket 20 in the front-rear direction to achieve rapid positioning of the plate 10 and the vehicle chassis.
[0036] The plate 10 protects the vehicle chassis, effectively preventing impurities such as stones and mud from directly contacting the chassis and its components, thus affecting the chassis's lifespan. The air duct 11 guides airflow under the vehicle. When the air duct 11 includes an arc-shaped section 111, this section effectively guides airflow during vehicle turns, reducing wind resistance, improving aerodynamics, and ultimately extending the vehicle's range. The positioning component 12 allows for quick positioning and connection between the plate 10 and the leg impact bracket 20 in the front-rear direction, ensuring accurate positioning of the plate 10 relative to the chassis. This reduces assembly difficulty, lowers the time cost for workers, facilitates assembly and disassembly of the plate 10, and improves operational convenience due to its simple structure.
[0037] Understandably, referring to Figure 1 The arched shape of the arc segment 111 mentioned above refers to the fact that it has an opening in the left and right directions.
[0038] In an example scheme, such as Figure 2 As shown, the front end of the air guide duct 11 is provided with a guide ramp 13. The height of the guide ramp 13 relative to the ground (i.e., the vertical distance from its lower end face to the ground) is configured to increase from front to back, so that the lower end face of the guide ramp 13 is tilted. This allows the airflow at the bottom of the vehicle to enter the air guide duct 11 through the guide ramp 13 during vehicle operation, and guides the airflow direction through the air guide duct 11. This helps to reduce the air resistance of the vehicle, adjust the lift force of the vehicle, and improve the aerodynamic performance of the vehicle.
[0039] Figure 7 This is a schematic diagram of the upper surface of the plate 10 and the leg anti-collision bracket 20 in one embodiment of the present invention. In one example, combined with... Figure 2 and Figure 7 The upper end of the plate 10 is provided with a first protrusion 112 at the position corresponding to the air guide groove 11. The connection between the first protrusion 112 and the plate 10 forms a reinforcing rib structure to increase the structural stability of the air guide groove 11. This avoids the problem of service life caused by the thinness of the plate 10 at the air guide groove 11, and helps to ensure the overall quality of the plate 10.
[0040] For example, the air guide 11 and the first boss 112 can be formed by injection molding or stamping.
[0041] For example, when the front end of the air guide trough 11 is provided with a guide ramp 13, the position of the first boss 112 corresponds to the air guide trough 11 and the guide ramp 13.
[0042] In one example scheme, combined Figure 1 and Figure 3 The lower end of the plate 10 is provided with a groove 14, and a mounting hole 141 is provided in the groove 14. A mounting component is installed in the mounting hole 141. The mounting component can pass through the mounting hole 141 to connect with the vehicle chassis, or pass through the mounting hole 141 to connect with the leg anti-collision bracket 20, so as to fix the plate 10 to the underside of the vehicle chassis.
[0043] For example, the sink 14 is partially or completely contained within the air guide 11, and the height of the bottom of the sink 14 relative to the ground (i.e., the vertical distance from its lower end face to the ground) is configured to be greater than or equal to the height of the bottom of the air guide 11 relative to the ground, i.e., the sink 14 is recessed into the air guide 11.
[0044] When a vehicle is driving on complex road conditions, such as on roads with lots of mud, sand, water, or gravel, if impurities enter the sedimentation trough 14, they can easily corrode the mounting components inside the sedimentation trough 14 after a long period of time, affecting the fixing quality and service life of the mounting components. This can easily lead to the plate 10 becoming loose, causing the plate 10 to shake relative to the vehicle chassis during vehicle operation, producing abnormal noises and affecting the driving and riding experience. By partially or completely arranging the sedimentation trough 14 within the air guide duct 11, the airflow in the air guide duct 11 can pass through the sedimentation trough 14, carrying away the impurities that enter or accumulate in the sedimentation trough 14, thereby helping to ensure the service life of the mounting components.
[0045] For example, such as Figure 7 As shown, a second boss 142 is provided at the upper end of the plate 10 at a position corresponding to the sink 14, and the mounting hole 141 passes through the second boss 142. A reinforcing rib structure is formed at the connection between the second boss 142 and the plate 10 to increase the structural strength of the plate 10.
[0046] When the plate 10 is connected to the leg bumper bracket 20, the upper end of the second protrusion 142 located at the front of the plate 10 contacts the lower end of the leg bumper bracket 20, so as to achieve contact positioning between the plate 10 and the leg bumper bracket 20 in the vertical direction. The mounting hole 141 engages with the mating hole opened on the leg bumper bracket 20, and is fixed by the mounting component. The second protrusion 142, together with the positioning component 12 and the first limiting component 15, can achieve rapid positioning of the plate 10 relative to the leg bumper bracket 20, which is beneficial to improving assembly efficiency.
[0047] For example, the mounting hole 141 is a screw hole, the mounting component is a bolt, and the plate 10 is installed by screw connection, which facilitates the disassembly and maintenance of the plate 10.
[0048] In an example scheme, such as Figure 3 As shown, the front end of the plate 10 is provided with a first limiting member 15 and a second limiting member 16. The first limiting member 15 extends in the front-rear direction, and the second limiting member 16 extends in the vertical direction. The upper end of the second limiting member 16 is connected to the first limiting member 15, and the lower end is connected to the plate 10. Figure 6 The first limiting member 15 and the limiting groove 22 on the leg anti-collision bracket 20 cooperate in the vertical direction. The first limiting member 15 can be accommodated in the limiting groove 22 to achieve the positioning of the plate 10 in the vertical direction.
[0049] For example, the aforementioned positioning member 12 protrudes from the front end of the second limiting member 16.
[0050] In an example scheme, such as Figure 3 As shown, the left and right ends of the plate 10 are provided with flanges 17. The height of the flanges 17 relative to the ground is configured to be greater than the height of the plate 10 relative to the ground. The flanges 17 cooperate with the plate 10 to form air guide grooves 11 at the left and right ends of the plate 10, so as to guide the airflow at the bottom of the vehicle, so as to avoid the airflow entering the gap between the vehicle chassis and the plate 10 and causing abnormal noise.
[0051] For example, such as Figure 3 As shown, the front of the flange 17 has an inclined section 171. The height of the inclined section 171 relative to the ground (i.e., the vertical distance from its lower end face to the ground) is configured to increase from front to back, so that the airflow at the bottom of the vehicle can be guided by the inclined section 171 and enter the air guide groove 11 formed by the flange 17 and the plate 10 during the vehicle's operation.
[0052] In one example, panel 10 is made of PVC (Polyvinyl chloride) sheet, which provides both protection and contributes to vehicle weight reduction. In another example, panel 10 is made of metal sheet, which provides good structural strength and helps extend service life.
[0053] In one embodiment, such as Figure 4 As shown, the vehicle chassis protection assembly proposed in this utility model also includes a leg anti-collision bracket 20. The leg anti-collision bracket 20 is located at the upper front end of the plate 10 and is connected to the front of the plate 10. A positioning groove 21 is provided at the rear end of the leg anti-collision bracket 20. The positioning groove 21 is connected to the positioning member 12. When the plate 10 is installed, the positioning member 12 is installed in the positioning groove 21 in the front-rear direction.
[0054] In one example, the positioning groove 21 extends through the leg anti-collision bracket 20 in the front-to-back direction.
[0055] In one example, the positioning element 12 is engaged within the positioning groove 21.
[0056] In one example, the number of positioning slots 21 is set to at least two, and the at least two positioning slots 21 are distributed in the left and right direction. The number of positioning members 12 is the same as that of positioning slots 21. With this setting, the positioning slots 21 can cooperate with the positioning members 12 to achieve the positioning of the plate 10 in the left and right direction, so as to avoid the positioning members 12 from tilting or shaking in the left and right direction, which helps to ensure the stability of the plate 10 installation and avoids the occurrence of abnormal noise problems.
[0057] In one example scheme, combined Figure 3 and Figure 6 The lower end of the leg anti-collision bracket 20 is provided with a limiting groove 22. The limiting groove 22 cooperates with the first limiting member 15 at the front end of the plate 10. When the plate 10 is installed, the first limiting member 15 is accommodated in the limiting groove 22 so as to realize the positioning of the plate 10 in the vertical and horizontal directions and the front and back directions.
[0058] In an example scheme, such as Figure 7 As shown, the lower end of the leg anti-collision bracket 20 is provided with a third protrusion 23. The third protrusion 23 protrudes towards the end close to the plate 10 in the vertical direction, and the lower end of the third protrusion 23 contacts the upper end of the plate 10. The third protrusion 23 is configured to be spaced apart from the second protrusion 142. The two work together to increase the connection contact area between the plate 10 and the leg anti-collision bracket 20, which is beneficial to ensuring the assembly quality of the plate 10.
[0059] This utility model also proposes a vehicle including the aforementioned vehicle chassis protection assembly, which can effectively reduce wind resistance, reduce noise, and improve vehicle comfort.
[0060] In one example configuration, plate 10 is positioned in the motor area of the vehicle to protect the motor.
[0061] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
