Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a spoiler device and a vehicle. Background Technology
[0002] When a vehicle turns, it experiences lateral tilt due to inertia, increasing the risk of skidding. This tilt is particularly pronounced when the vehicle is turning at high speed, reducing stability and compromising safety. Utility Model Content
[0003] The purpose of this application is to provide a spoiler and a vehicle that aims to solve the problem of how to reduce the body roll force when the vehicle is turning.
[0004] In a first aspect, a spoiler is provided for a vehicle, the vehicle including a body. The spoiler includes a spoiler assembly adapted to be attached to the bottom of the body.
[0005] The spoiler assembly includes a first spoiler and a second spoiler arranged along the width direction of the vehicle. The surface of the first spoiler facing away from the second spoiler includes a first guide surface, and the surface of the second spoiler facing away from the first spoiler is a second guide surface. Along the direction from the front of the vehicle to the rear, the first guide surface and the second guide surface gradually move away from each other.
[0006] For ease of explanation, the side closer to the first spoiler in the vehicle's width direction is designated as the first side, and the side closer to the second spoiler is designated as the second side. In the above design, the first and second spoilers are arranged along the width direction at the bottom of the vehicle, and in the direction from the front to the rear of the vehicle, the first guide surface of the first spoiler and the second guide surface of the second spoiler gradually move away from each other. This causes the distance between the first and second guide surfaces to gradually increase in the direction from the front to the rear of the vehicle; that is, the first guide surface extends towards the first side of the vehicle in the direction from the front to the rear, and the second guide surface extends towards the second side of the vehicle in the direction from the front to the rear.
[0007] When the vehicle turns towards the first side, the body generates a lateral tilt force towards the second side. As the second guide surface gradually extends towards the second side of the vehicle from the front to the rear, it receives airflow from the second side of the vehicle. This airflow acts on the second guide surface, generating a first thrust towards the first side of the vehicle on the second spoiler. The direction of the first thrust is opposite to the direction of the lateral tilt force when the vehicle turns towards the first side, thereby offsetting part of the lateral tilt force and improving the stability of the vehicle when turning towards the first side.
[0008] When the vehicle turns toward the second side, the body generates a lateral tilt force toward the first side. As the first guide surface gradually extends toward the first side of the vehicle from the front to the rear, it receives airflow from the first side of the vehicle. This airflow acts on the first guide surface, generating a second thrust toward the second side of the vehicle on the first spoiler. The direction of the second thrust is opposite to the direction of the lateral tilt force when the vehicle turns toward the second side, thereby offsetting part of the lateral tilt force and improving the stability of the vehicle when turning toward the second side.

[0048] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.
[0049] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0052] When a vehicle 100 turns, its body 10 will generate a roll force due to inertia, which can cause the vehicle 100 to skid. Especially for some high-speed supercars, the roll force during cornering is one of the main factors affecting the stability of its body 10. This application provides a spoiler device installed on the body 10 to reduce the roll force of the vehicle 100 during cornering, thereby improving the stability of the vehicle body 10 when cornering.
[0053] Among them, vehicle 100 can be a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, a gasoline vehicle, etc. Vehicle 100 can also be a sedan, a truck, a bus, a lorry, a trailer, etc. This application does not specifically limit the type of vehicle 100.
[0054] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in an embodiment of this application. The vehicle 100 includes a body 10, which can be used to carry passengers and install the components required for the vehicle 100.
[0055] See Figure 2 , Figure 2 for Figure 1 The diagram shows the structure of the vehicle 100 from another perspective. For ease of understanding, this embodiment is described using an electric vehicle 100 with a spoiler as an example. For the electric vehicle 100, the body 10 includes a frame, which can be used to mount components such as a battery pack. The battery pack provides electrical energy to the vehicle 100, which is then converted into mechanical energy by components such as a motor to drive the vehicle 100.
[0056] To protect the vehicle 100, a front subframe mudguard 50 can be installed at the bottom of the frame. During vehicle 100 operation, the front subframe mudguard 50 can prevent stones, sand, and other foreign objects kicked up by the wheels 20 from splashing onto the sides of the vehicle body 10, thus preventing scratches or corrosion to the paint and protecting the vehicle 100. The battery pack can be located on the side of the front subframe mudguard 50 near the rear 40 of the vehicle.
[0057] To prevent damage to the battery pack from impacts, a bumper bar 60 can be installed on the side of the battery pack closest to the front of the vehicle 30, specifically on the side of the frame closest to the road surface. During vehicle 100 operation, if there are protruding objects on the road, the bumper bar 60 will collide with them, preventing the battery pack from directly colliding with the object and protecting it. Additionally, the battery pack may include a main body and a protective plate 70 located at the bottom of the main body. The protective plate 70 is connected to the frame, covering the side of the battery pack closest to the road surface to prevent damage from flying stones, sand, etc., during vehicle 100 operation.
[0058] In some real-time methods, see Figure 2 and Figure 3 The spoiler assembly includes a first spoiler 11 and a second spoiler 12 arranged along the width direction of the vehicle 100. The surface of the first spoiler 11 facing away from the second spoiler 12 includes a first guide surface 111, and the surface of the second spoiler 12 facing away from the first spoiler 11 is a second guide surface 121. Along the direction from the front 30 to the rear 40 of the vehicle 100, the first guide surface 111 and the second guide surface 121 gradually move away from each other.
[0059] For ease of explanation, the side of the vehicle 100 closer to the first spoiler 11 in the width direction is named the first side 41, and the side closer to the second spoiler 12 is named the second side 42. In the above scheme, the first spoiler 11 and the second spoiler 12 are arranged along the width direction at the bottom of the vehicle 100, and in the direction from the front 30 to the rear 40 of the vehicle 100, the first guide surface 111 of the first spoiler 11 and the second guide surface 121 of the second spoiler 12 gradually move away from each other. This makes the distance between the first guide surface 111 and the second guide surface 121 gradually increase in the direction from the front 30 to the rear 40, that is, the first guide surface 111 extends toward the first side 41 of the vehicle 100 in the direction from the front 30 to the rear 40, and the second guide surface 121 extends toward the second side 42 of the vehicle 100 in the direction from the front 30 to the rear 40.
[0060] When the vehicle 100 turns toward the first side 41, the body 10 generates a lateral tilt force toward the second side 42. As the second guide surface 121 gradually extends toward the second side 42 of the vehicle 100 along the direction from the front 30 to the rear 40, the second guide surface 121 receives the airflow from the direction of the second side 42 of the vehicle 100. This airflow acts on the second guide surface 121 and generates a first thrust toward the first side 41 of the vehicle 100 on the second spoiler 12. The direction of the first thrust is opposite to the direction of the lateral tilt force of the body 10 when the vehicle 100 turns toward the first side 41, thereby offsetting part of the lateral tilt force of the body 10 and improving the stability of the vehicle 100 when turning toward the first side 41.
[0061] When the vehicle 100 turns toward the second side 42, the body 10 generates a lateral tilt force toward the first side 41. As the first guide surface 111 gradually extends toward the first side 41 of the vehicle 100 from the front 30 toward the rear 40, the first guide surface 111 receives the airflow from the first side 41 of the vehicle 100. This airflow acts on the first guide surface 111, generating a second thrust toward the second side 42 of the vehicle 100 on the first spoiler 11. The direction of the second thrust is opposite to the direction of the lateral tilt force of the body 10 when the vehicle 100 turns toward the second side 42, thereby offsetting part of the lateral tilt force of the body 10 and improving the stability of the vehicle 100 when turning toward the second side 42.
[0062] In some examples, the first spoiler 11 and the second spoiler 12 are integral structures, connected to the vehicle body 10 through a common connecting structure, and the first guide surface 111 and the second guide surface 121 are provided along the width direction of the vehicle 100.
[0063] In other examples, the first spoiler 11 and the second spoiler 12 are two separate components, which are respectively connected to the bottom of the vehicle body 10.
[0064] In some examples, along the height direction of the vehicle 100, the first guide surface 111 and the second guide surface 121 are perpendicular to the road surface.
[0065] In other examples, along the height direction of the vehicle 100, the first guide surface 111 and the second guide surface 121 form an angle with the road surface. Specifically, the angle between the first guide surface 111 and the road surface in the direction towards the first side 41 of the vehicle 100 is greater than 90°, and the angle between the second guide surface 121 and the road surface in the direction towards the second side 42 of the vehicle 100 is also greater than 90°. In this way, when the vehicle 100 turns, the airflow blowing towards the first guide surface 111 or the second guide surface 121 not only provides a lateral force opposite to the direction of the roll force on the vehicle 100, but also provides downforce towards the road surface, improving the grip of the vehicle 100 and thus improving the stability of the vehicle 100 when turning.
[0066] In some examples, the first guide surface 111 and the second guide surface 121 have the same dimensions in the height direction of the vehicle 100, along the direction from the front 30 to the rear 40.
[0067] In other examples, along the direction from the front 30 to the rear 40, the dimensions of the first guide surface 111 and the second guide surface 121 gradually increase in the height direction of the vehicle 100.
[0068] In some implementations, see Figure 2 and Figure 3 The first spoiler 11 and the second spoiler 12 are symmetrically arranged with respect to the length direction of the vehicle 100. This allows the vehicle 100 to provide the same lateral force to the body 10 through the second spoiler 12 and the first spoiler 11 when turning towards the first side 41 and towards the second side 42, respectively, thereby improving the stability of the body 10 when the vehicle 100 turns.
[0069] It should be noted that the first spoiler 11 and the second spoiler 12 referred to in this embodiment are symmetrically arranged with respect to the length direction of the vehicle 100, meaning that the mirror image of the first spoiler 11 and the second spoiler 12 extends along the length direction of the vehicle 100.
[0070] In other embodiments, the first spoiler 11 and the second spoiler 12 are arranged asymmetrically with respect to the length direction of the vehicle 100.
[0071] In some implementations, see Figures 2-7 ,in, Figure 4 This is a three-dimensional schematic diagram of the first spoiler 11. Figure 5 This is a schematic front view of the first spoiler 11. Figure 6 This is a schematic diagram of the right side view of the first spoiler 11. Figure 7 This is a bottom view of the first spoiler 11. The first guide surface 111 includes a first part 111a and a second part 111b. The first part 111a is parallel to the length direction of the vehicle 100, and the second part 111b is connected to the end of the first part 111a near the rear 40 of the vehicle and is an arc-shaped surface that protrudes toward the second spoiler 12.
[0072] In the above scheme, the first portion 111a of the first guide surface 111 is parallel to the length direction of the vehicle 100. When the vehicle 100 is moving, the first portion 111a acts as a guide, extending in the direction from the front 30 to the rear 40 of the vehicle. The direction in which the first portion 111a extends is the same as the direction of airflow movement, reducing the resistance to airflow and thus reducing the drag of the vehicle 100 when it is moving. Setting the second portion 111b as an arc-shaped surface protruding towards the second spoiler 12 can improve the resistance of the second portion 111b to airflow when the vehicle 100 turns. When the vehicle 100 turns towards the second side 42, the airflow outside the turning direction acts on the second portion 111b, generating a thrust towards the second side 42 of the vehicle 100, which counteracts part of the roll force generated when the vehicle 100 turns, improving the stability of the vehicle body 10 when the vehicle 100 turns.
[0073] It should be understood that since the first spoiler 11 and the second spoiler 12 are mirror images of each other with respect to the length direction of the vehicle 100, that is, the structures of the second guide surface 121 and the first guide surface 111 are also mirror images of each other with respect to the length direction of the vehicle 100, the specific structure of the second guide surface 121 can be referred to the structure of the first guide surface 111, and will not be described in detail here.
[0074] For details on the structure of the second spoiler 12, please refer to [link / reference needed]. Figures 8-11 , Figure 8 This is a schematic diagram of the three-dimensional structure of the second spoiler 12. Figure 9 This is a schematic diagram of the main view of the second spoiler 12. Figure 10 This is a schematic diagram of the right side view of the second spoiler 12. Figure 11 This is a bottom view schematic diagram of the second spoiler 12.
[0075] In some examples, the first part 111a and the second part 111b are a single structure.
[0076] In other examples, the first part 111a and the second part 111b are separate components. The first part 111a and the second part 111b can be a movable connection, such as an overlapping connection; or they can be a detachable connection, such as a connection by bolts.
[0077] In some specific examples, the first part 111a and the second part 111b are tangent. In this way, the connection between the first part 111a and the second part 111b is smooth, reducing resistance to airflow and thus reducing the drag of the vehicle 100 when it is in motion.
[0078] In other examples, the first part 111a and the second part 111b are transitioned by a slope or a circular arc.
[0079] In some embodiments, the radius of curvature of the second part 111b gradually increases along the direction from the front 30 to the rear 40 of the vehicle 100. Since the airflow direction at the bottom of the vehicle body 10 is parallel or approximately parallel to the length direction of the vehicle 100 when the vehicle 100 is traveling in a straight line, the gradual increase in the radius of curvature of the second part 111b along the direction from the front 30 to the rear 40 of the vehicle 100 causes the angle between the tangent of the arc-shaped surface and the length direction of the vehicle 100 to gradually decrease. This reduces the resistance between the second part 111b and the airflow when the vehicle 100 is traveling in a straight line, thereby reducing the driving resistance of the vehicle 100.
[0080] In other examples, the radius of curvature of the second part 111b remains unchanged along the direction from the front 30 to the rear 40 of the vehicle 100.
[0081] In some embodiments, the spoiler includes multiple spoiler components arranged along the length of the vehicle 100. Simultaneous arrangement of multiple spoiler components can improve the stability of the vehicle 100 during cornering.
[0082] In some examples, the number of spoiler components can be 2, 3, 4, etc.
[0083] For some specific examples, see Figure 2 There can be three spoiler components, arranged along the direction from the front 30 to the rear 40 of the vehicle, namely, first spoiler component 1, second spoiler component 2, and third spoiler component 3. It should be noted that the working principle of the first spoiler component 1, second spoiler component 2, and third spoiler component 3 is the same. The difference lies in their installation position on the bottom of the vehicle 100. The installation position and structure of the first spoiler component 1 can be found in [reference needed]. Figure 2 and Figure 3 The installation location and structure of the second aerodynamic component 2 can be found in [reference needed]. Figure 2 and Figure 12 The installation location and structure of the third spoiler component 3 can be found in [reference]. Figure 2 and Figure 21 .
[0084] When the spoiler assembly includes a first spoiler assembly 1, a second spoiler assembly 2, and a third spoiler assembly 3, the first spoiler assembly 1 includes a first spoiler 11 and a second spoiler 12, the second spoiler assembly 2 includes a third spoiler 21 and a fourth spoiler 22, and the third spoiler assembly 3 includes a fifth spoiler 31 and a sixth spoiler 32. Relative to the length direction of the vehicle 100, the first spoiler 11 is a mirror image of the second spoiler 12, the third spoiler 21 is a mirror image of the fourth spoiler 22, and the fifth spoiler 31 is a mirror image of the sixth spoiler 32. The first spoiler 11, the third spoiler 21, and the fifth spoiler 31 are located on the side of the vehicle body 10 closest to the first side 41, and the second spoiler 12, the fourth spoiler 22, and the sixth spoiler 32 are located on the side of the vehicle body 10 closest to the second side 42.
[0085] It should be understood that the third spoiler 21 may include a third guide surface 211, which may include a third portion 211a and a fourth portion 211b. The fourth spoiler 22 may include a fourth guide surface 221. The third portion 211a of the third guide surface 211 may be configured with reference to the first portion 111a of the first guide surface 111, and the fourth portion 211b of the third guide surface 211 may be configured with reference to the second portion 111b of the first guide component. Since the fourth guide component and the third guide component are mirror images of each other with respect to the length direction of the vehicle 100, the fourth guide surface 221 of the fourth guide component is also a mirror image of the third guide surface 211 of the third guide component; this will not be elaborated further here.
[0086] The specific structure of the third spoiler 21 can be found in [reference needed]. Figures 13-16 , Figure 13 This is a three-dimensional structural diagram of the third spoiler 21. Figure 14 This is a schematic front view of the third spoiler 21. Figure 15 This is a schematic diagram of the right side view of the third spoiler 21. Figure 16 This is a bottom view of the third spoiler 21. For the specific structure of the fourth spoiler 22, please refer to [reference needed]. Figures 17-20 , Figure 17 This is a three-dimensional structural diagram of the fourth spoiler 22. Figure 18 This is a schematic front view of the fourth spoiler 22. Figure 19 This is a schematic diagram of the right side view of the fourth spoiler 22. Figure 20 This is a bottom view schematic diagram of the fourth spoiler 22.
[0087] Similarly, the fifth spoiler 31 may include a fifth guide surface 311, which may include a fifth part 311a and a sixth part 311b.
[0088] The sixth spoiler 32 may include a sixth guide surface 321. The fifth portion 311a of the fifth guide surface 311 can be configured with reference to the first portion 111a of the first guide surface 111, and the sixth portion 311b of the fifth guide surface 311 can be configured with reference to the second portion 111b of the first guide component. Since the sixth guide component and the fifth guide component are mirror images of each other relative to the length direction of the vehicle 100, the sixth guide surface 321 of the sixth guide component is also a mirror image of the fifth guide surface 311 of the fifth guide component; this will not be elaborated further here.

[0090] For ease of explanation, the embodiments of this application mainly describe the structure of the first spoiler 11 in detail. The structures of the other spoilers can be referred to the structure of the first spoiler 11, and will not be repeated here.
[0091] In some examples, the first spoiler component 1, the second spoiler component 2, and the third spoiler component 3 are the same size and shape.
[0092] In other examples, the first spoiler component 1, the second spoiler component 2, and the third spoiler component 3 have different sizes and shapes.
[0093] In some implementations, see Figures 4-7 The first spoiler 11 includes a fixing part 112 and a spoiler part 113. The fixing part 112 is adapted to be connected to the vehicle body 10. The spoiler part 113 is connected to the fixing part 112 and includes a first guide surface 111. The spoiler part 113 is connected to the vehicle body 10 through the fixing part 112, which has a simple structure and is easy to disassemble.
[0094] In some examples, the spoiler 113 and the fixing part 112 are an integral structure.
[0095] In other examples, the spoiler 113 is detachably connected to the fixing part 112, for example, the spoiler 113 and the fixing part 112 are connected by components such as clips and bolts.
[0096] In some examples, the fixing part 112 may include a fixing plate, which can be connected to the body 10 by means of connectors or by welding, etc., which is simple in structure and easy to connect.
[0097] In other examples, the fixing part 112 is provided with a connecting hole, which is suitable for connecting the vehicle body 10. By providing a connecting hole in the fixing part 112 to connect with the vehicle body 10, the structure is simple and easy to disassemble.
[0098] In some other examples, the fixing part 112 includes a plurality of fixing ears, which are connected to the vehicle body 10. For example, the fixing ears can be provided with connecting holes, and bolts or the like can be inserted through the connecting holes to connect to the vehicle body 10.
[0099] In some embodiments, the spoiler 113 includes a spoiler. By configuring the spoiler 113 as a spoiler, the weight of the first spoiler 11 can be effectively reduced, thereby reducing the weight of the vehicle 100.
[0100] It should be understood that the connection structure between the second spoiler 12, the third spoiler 21, the fourth spoiler 22, the fifth spoiler 31, and the sixth spoiler 32 and the vehicle frame can be set with reference to the connection structure between the first spoiler 11 and the vehicle frame, and will not be described in detail here.
[0101] In some examples, the spoiler 113 includes a spoiler plate whose thickness direction is arranged along the width direction of the vehicle 100, and the side of the spoiler plate facing away from the second spoiler 12 is a first spoiler surface.
[0102] In some embodiments, the first spoiler 11 is a flexible structure. Since the first spoiler 11 is located at the bottom of the vehicle body 10, when the first spoiler 11 is deformed by foreign objects on the road surface, the flexible structure can automatically rebound and recover, thereby improving the wear resistance of the first spoiler 11.
[0103] In some examples, the material of the first spoiler 11 may be rubber.
[0104] In other examples, the spoiler portion 113 of the first spoiler 11 is rotatably connected to the fixed portion 112 and is provided with a torsion spring. One support of the torsion spring acts on the fixed portion 112, and the other support acts on the spoiler portion 113. When the spoiler portion 113 collides with a foreign object, the spoiler portion 113 can rotate relative to the fixed portion 112 to prevent itself from deforming. After the vehicle 100 passes the foreign object, the spoiler portion 113 returns to its original position under the action of the torsion spring.
[0105] In some implementations, see Figure 2 and Figure 3 The spoiler assembly of the spoiler device includes a first spoiler assembly 1, which is connected to the bottom of the front subframe mudguard 50. Since the front subframe mudguard 50 is located on the side of the vehicle 100 closer to the front of the vehicle 30 in the length direction, connecting the first spoiler assembly 1 to the bottom of the front subframe mudguard 50 improves the stability of the front of the vehicle 100 when turning.
[0106] In some examples, the first spoiler assembly 1 is connected to the front subframe fender 50.
[0107] In other examples, the first spoiler assembly 1 and the front subframe fender 50 are an integral structure.
[0108] In some specific examples, the frame has a first mounting hole, the front subframe fender 50 has a first assembly hole, and the first spoiler assembly 1 has a first connection hole 114. The vehicle 100 also includes a first fastener that passes through the first connection hole 114, the first assembly hole, and the first mounting hole to connect the first spoiler assembly 1 to the vehicle body 10.
[0109] In the above solution, the first fastener passes through the first connecting hole 114, the first assembly hole, and the first mounting hole. That is, the first connecting hole 114 of the first spoiler assembly 1 shares the first mounting hole of the frame with the first assembly hole of the front subframe mudguard 50. This allows the first spoiler assembly 1 to be connected to the frame through the original first mounting hole of the front subframe mudguard 50 of the vehicle 100, without the need to redesign the connection structure, reducing processing steps and lowering costs.
[0110] In some examples, the connection hole of the fixing part 112 includes a first connection hole 114.
[0111] In some examples, the first spoiler assembly 1 includes a plurality of first connecting holes 114, which are respectively disposed on the first spoiler 11 and the second spoiler 12. The frame includes a plurality of first mounting holes, and the arrangement of the plurality of first connecting holes 114 on the first spoiler 11 and the second spoiler 12 is the same as the arrangement of the plurality of first mounting holes on the frame. Both the first spoiler 11 and the second spoiler 12 are connected to the first mounting holes of the frame through the first connecting holes 114.
[0112] In some examples, the number of first connection holes 114 can be 4, 5, 6, etc.
[0113] In some implementations, see Figure 2 and Figure 12The spoiler assembly includes a second spoiler assembly 2, which is connected to the bottom of the front subframe fender 50 and the bottom of the battery pack. Since the front subframe fender 50 is located along the length of the vehicle 100 near the front end 30, and the battery pack is located along the length of the vehicle 100 near the center of the body 10, connecting the second spoiler assembly 2 to the bottom of the front subframe fender 50 and the bottom of the battery pack improves the stability of the front part of the body 10 when the vehicle 100 is turning.
[0114] In some examples, a portion of the third spoiler 21 in the second spoiler assembly 2 is connected to the frame at the position of the front subframe fender 50, and another portion is connected to the body of the battery pack.
[0115] In some specific embodiments, the vehicle frame is provided with a second mounting hole, and the front subframe mudguard 50 is provided with a second mounting hole. The battery pack body is provided with a third mounting hole, and the protective plate 70 is provided with a third mounting hole. The second spoiler assembly 2 is provided with a second connecting hole 212 and a third connecting hole 213. The vehicle 100 also includes a second fastener and a third fastener. The second fastener passes through the second connecting hole 212, the second mounting hole, and the second mounting hole, and the third fastener passes through the third connecting hole 213, the third mounting hole, and the third mounting hole to connect the spoiler assembly to the vehicle body 10.
[0116] In the above solution, since the vehicle frame originally has a second mounting hole for engaging with the second mounting hole of the front subframe mudguard 50, and a third mounting hole for fixing the protective plate 70, the second connecting hole 212 of the second spoiler assembly 2 can be directly connected to the original second mounting hole of the vehicle frame, and the third connecting hole 213 can be directly connected to the original third mounting hole of the vehicle frame. This reduces the number of holes required and lowers production costs.
[0117] In some examples, there may be one or more second connection holes 212.
[0118] In some examples, there may be one or more third connection holes 213.
[0119] In some examples, the bottom of the battery pack has a fourth mounting hole, and the protective plate 70 has a corresponding clearance hole for the fourth mounting hole. The second spoiler assembly 2 has a fourth connecting hole 214, which is connected to the fourth mounting hole by bolts or clips.
[0120] In some embodiments, the vehicle 100 also includes a snap-fit structure through which the second spoiler assembly 2 is connected to the bumper bar 60. Since the bumper bar 60 is located between the front subframe fender 50 and the battery pack, connecting the second spoiler assembly 2 to the bumper bar 60 increases the number of connection points and improves the stability of the connection between the second spoiler assembly 2 and the vehicle body 10. Furthermore, the snap-fit structure allows for quick connection and convenient operation.
[0121] In some examples, the snap-fit structure includes an expansion buckle. A fifth mounting hole can be machined in the bumper 60, and a fifth connecting hole 215 can be provided in the second spoiler assembly 2. The expansion buckle passes through the fifth connecting hole 215 and the fifth mounting hole to connect the second spoiler assembly 2 to the bumper 60.
[0122] In other embodiments, the second spoiler assembly 2 and the anti-collision bar 60 are connected by bolts.
[0123] In some implementations, see Figure 2 and Figure 21 The spoiler assembly of the spoiler device includes a third spoiler assembly 3, which is connected to the bottom of the battery pack and located at one end of the battery pack near the rear of the vehicle 40. By setting the third spoiler assembly 3 at the end of the battery pack near the rear of the vehicle 40, the stability of the middle and rear parts of the vehicle body 10 is improved when the vehicle 100 turns.
[0124] In some examples, the battery pack body includes a sixth mounting hole, the protective plate 70 includes a fourth mounting hole, and the third spoiler assembly 3 includes a sixth connecting hole 312. The third spoiler assembly 3 is fixed to the battery pack by bolts passing through the sixth connecting hole 312, the fourth mounting hole, and the sixth mounting hole.
[0125] In the above scheme, the third turbulence component 3 and the protective plate 70 share the sixth mounting hole on the battery pack body, which reduces the processing steps of the mounting structure and lowers the cost.
[0126] In some examples, the battery pack includes a seventh mounting hole, the third spoiler assembly 3 includes a seventh connection hole 313, the protective plate 70 is provided with a second clearance hole, and the seventh mounting hole and the seventh connection hole 313 can be connected by an expansion snap.
