[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 4 The spoiler structure 100 for a vehicle according to the first embodiment of the utility model is described. The spoiler structure 100 can be used in a vehicle (not shown). In the following description of the application, the spoiler structure 100 is used in a vehicle as an example for detailed description.

[0028] like Figure 1 As shown, a spoiler structure 100 for a vehicle according to an embodiment of the first aspect of the utility model comprises a protective device 1 and a spoiler 2 .

[0029] Specifically, the spoiler 2 is detachably connected to the lower side of the protective device 1, and the spoiler 2 can be bent when subjected to external force. Figure 1 In the example of , the spoiler 2 is located on the front side of the protective device 1, and the upper side of the spoiler 2 is detachably connected to the lower side of the protective device 1. With such a configuration, the spoiler 2 has a simple structure and is easy to install and remove. The spoiler 2 can be connected to other components of the vehicle through the protective device 1, which is conducive to the installation and use of the spoiler 2 and is not easily affected by the shape of the vehicle, thereby improving the versatility of the spoiler structure 100. In addition, when the vehicle collides with other vehicles or objects, the protective device 1 can protect the components of the vehicle to avoid damage to the components of the vehicle, and can also protect the above-mentioned other vehicles to avoid damage to the above-mentioned other vehicles, thereby extending the service life of the vehicle and the above-mentioned other vehicles.

[0030] When the spoiler structure 100 is used for a vehicle, during the driving of the vehicle, the spoiler 2 can reduce the drag coefficient of the vehicle during driving, thereby reducing the energy consumption of the vehicle, increasing the grip of the vehicle, improving the stability of the vehicle, and then reducing the cost of driving the vehicle, and also improving the safety of the vehicle during driving. In addition, when the vehicle passes an obstacle (for example, a curb stone on the side of the road), the spoiler 2 can bend to avoid the obstacle after hitting the obstacle, thereby avoiding the obstacle from blocking the driving of the vehicle, improving the passability of the vehicle, and also avoiding the spoiler 2 from being damaged when the vehicle passes the obstacle, thereby extending the service life of the spoiler 2. Moreover, after the vehicle passes the obstacle, that is, when the external force on the spoiler 2 disappears, the spoiler 2 can return to its original position to continue to play the role of spoiler, thereby improving the use performance of the spoiler 2.

[0031] According to the spoiler structure 100 for vehicles of the utility model, the spoiler 2 has a simple structure and is easy to install and disassemble. The spoiler 2 can be connected to other parts of the vehicle through the protective device 1, which is conducive to the installation and use of the spoiler 2 and is not easily affected by the shape of the vehicle, thereby improving the versatility of the spoiler structure 100. When the spoiler structure 100 is used for a vehicle, the spoiler 2 reduces the wind resistance coefficient during the vehicle's driving process, thereby reducing the energy consumption of the vehicle, increasing the vehicle's grip, and then reducing the cost of the vehicle's driving, and also improving the safety of the vehicle during driving. In addition, when passing through an obstacle, the spoiler 2 can be bent to avoid, thereby improving the vehicle's passability. Moreover, after passing through the obstacle, the spoiler 2 can return to its original position to play a spoiler role, thereby improving the usability of the spoiler 2.

[0032] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The spoiler structure 100 further includes at least one fastener 3, which passes through the spoiler 2 and is connected to the protective device 1. Figure 2 and Figure 3 In the example, the fastener 3 passes through the overlapping portion of the spoiler 2 and the protective device 1 in the front-to-back direction (i.e., the upper side of the spoiler 2) and is connected to the protective device 1. As a result, the fastener 3 strengthens the connection between the spoiler 2 and the protective device 1, and the connection is more firm, thereby improving the use stability of the spoiler structure 100, which is conducive to the long-term and stable use of the spoiler structure 100. In addition, the fastener 3 is easy to install and disassemble, which is conducive to the maintenance and replacement of the spoiler 2, and the use cost of the fastener 3 is low, which reduces the production cost of the spoiler structure 100. But it is not limited to this.

[0033] Optionally, the fastener 3 can be set as a bolt or a rivet, but is not limited thereto. For example, when the fastener 3 is a bolt, the bolt is threadedly connected to the protective device 1. On the one hand, the contact area between the fastener 3 and the protective device 1 is increased, and the stability of the connection between the fastener 3 and the protective device 1 and the spoiler 2 is improved, thereby improving the use stability of the spoiler structure 100. On the other hand, it is convenient to disassemble the fastener 3 and the protective device 1, so that the fastener 3 can be reused, thereby improving the utilization rate of the fastener 3. When the fastener 3 is a rivet, the rivet is riveted to the spoiler 2 and the protective device 1, which facilitates the fastener 3 to be quickly assembled with the spoiler 2 and the protective device 1, thereby improving the assembly efficiency of the spoiler structure 100.

[0034] Further, refer to Figure 2 There are multiple fasteners 3, and the multiple fasteners 3 are arranged along the length direction of the spoiler 2 (for example Figure 2 In the description of the present utility model, "multiple" means two or more. For example, in Figure 2 In the example, six fasteners 3 are provided, and the six fasteners 3 are arranged at unequal intervals along the left and right directions. Thus, multiple fasteners 3 can fix the spoiler 2 and the protective device 1 from the left and right sides and the middle area of ​​the spoiler 2, thereby further improving the connection strength between the spoiler 2 and the protective device 1, preventing the spoiler 2 from falling from the protective device 1, and further improving the use stability of the spoiler structure 100. But not limited to this. It should be noted that the number and arrangement of the fasteners 3 can be specifically set according to actual use to better meet practical applications.

[0035] According to some embodiments of the present invention, referring to Figure 2 , the width of the spoiler 2 is d, wherein d satisfies: 40mm≤d≤60mm. For example, when the width d of the spoiler 2 is less than 40mm, the width of the spoiler 2 is small. When the vehicle is traveling at a high speed, the wind resistance coefficient reduced by the spoiler 2 is small, thereby reducing the fuel consumption of the vehicle. When the width d of the spoiler 2 is greater than 60mm, the width of the spoiler 2 is large. When the vehicle is at an obstacle, the lower side of the spoiler 2 is prone to collide with a smaller obstacle. After the spoiler 2 is collided for a long time, the spoiler 2 is prone to damage, thereby shortening the service life of the spoiler 2. In addition, the material consumption of the spoiler 2 is increased, thereby increasing the production cost of the spoiler 2, and increasing the production cost of the spoiler structure 100.

[0036] Thus, by setting the width d of the spoiler 2 to satisfy: 40mm≤d≤60mm, the width of the spoiler 2 is reasonably set, so that when the vehicle is traveling at a high speed, the spoiler 2 reduces the drag coefficient to a greater extent, thereby reducing the fuel consumption of the vehicle to a greater extent, increasing the vehicle's grip, thereby reducing the vehicle's driving cost, improving the vehicle's driving stability, and improving the vehicle's safety. In addition, when the vehicle passes a smaller obstacle, the spoiler 2 is also prevented from colliding with the smaller obstacle, thereby preventing the spoiler 2 from being collided for a long time, avoiding damage to the spoiler 2, and thus extending the service life of the spoiler 2. In addition, the material consumption of the spoiler 2 is reduced, thereby reducing the production cost of the spoiler 2, thereby reducing the production cost of the spoiler 2, and thus reducing the production cost of the spoiler structure 100.

[0037] According to some embodiments of the present invention, referring to Figure 3 , the thickness of the spoiler 2 is w, wherein w satisfies: 3mm≤w≤4mm. For example, when the thickness w of the spoiler 2 is less than 3mm, the thickness of the spoiler 2 is small, and the spoiler 2 is easily bent under the action of air resistance during the driving of the vehicle, thereby weakening the effect of the spoiler 2 on reducing the drag coefficient. When the thickness w of the spoiler 2 is greater than 4mm, the thickness of the spoiler 2 is large, and the deformation of the spoiler 2 is small, that is, when the spoiler 2 collides with an obstacle, the spoiler 2 is not easy to bend, thereby reducing the vehicle's passability. In addition, the material consumption of the spoiler 2 is also increased, and the production cost of the spoiler 2 is increased. Thus, by setting the thickness w of the spoiler 2 to meet the following conditions: 3mm≤w≤4mm, the thickness w of the spoiler 2 is reasonably set. During the driving process of the vehicle, the spoiler 2 is not easy to bend under the action of air resistance, thereby enhancing the effect of the spoiler 2 in reducing the drag coefficient, reducing the fuel consumption of the vehicle, increasing the grip of the vehicle, and thus reducing the cost of the vehicle driving, and also improving the stability and safety of the vehicle driving. In addition, the deformation of the spoiler 2 is increased, that is, when the spoiler 2 collides with an obstacle, the spoiler 2 is easy to bend, thereby improving the passability of the vehicle. In addition, the material consumption of the spoiler 2 is also reduced, thereby reducing the production cost of the spoiler 2.

[0038] According to some embodiments of the utility model, the spoiler 2 is a rubber part. The rubber part is easy to shape, so it is convenient for the spoiler 2 to be molded, thereby reducing the difficulty of production of the spoiler 2 and improving the production rate of the spoiler 2. In addition, the rubber part is elastic and can be deformed, so that when the spoiler 2 collides with an obstacle, the spoiler 2 can be bent to avoid the obstacle, thereby improving the use performance of the spoiler 2 and improving the passability of the vehicle. For example, the rubber can be made of thermoplastic elastomer (TPE), which has high elasticity, aging resistance and oil resistance, thereby effectively extending the service life of the spoiler 2, thereby extending the service life of the spoiler structure 100. Or, the rubber can be made of thermoplastic vulcanized rubber (TPV), which has solvent and oil resistance, and has good resilience, so that the spoiler 2 is easy to return to its original state after bending, which is conducive to the normal use of the spoiler 2 for a long time. But it is not limited to this.

[0039] According to some embodiments of the present invention, referring to Figure 3 The spoiler structure 100 further includes at least one connecting bracket 4, which is disposed on a side of the protective device 1 away from the spoiler 2, and the protective device 1 is suitable for connecting to the vehicle through the connecting bracket 4. Figure 3 In the example of FIG. 1 , the connecting bracket 4 is located at the rear side of the protective device 1. Thus, the spoiler structure 100 is installed with other components of the vehicle through the connecting bracket 4, which reduces the difficulty of installation and facilitates the installation of the spoiler structure 100 and other components of the vehicle, thereby improving the installation efficiency of the vehicle. For example, along the length direction of the spoiler 2 (for example Figure 1 There may be a plurality of connecting brackets 4 (in the left and right directions), and the plurality of connecting brackets 4 are arranged at intervals along the left and right directions. There may be two connecting brackets 4, and the two connecting brackets 4 are respectively located at the left and right ends of the protective device 1. Thus, the installation stability of the spoiler device 100 and other components of the vehicle is further improved, thereby further improving the use stability of the spoiler structure 100. However, it is not limited thereto. It should be noted that the number and arrangement of the connecting brackets 4 can be specifically set according to actual use to better meet practical applications.

[0040] Optionally, the spoiler 2 can be set to a rectangular parallelepiped shape. As a result, the spoiler 2 has a simple structure and is easy to process, thereby improving the production efficiency of the spoiler 2. In addition, while avoiding the spoiler 2 from colliding with obstacles, the windward area of ​​the spoiler 2 is also increased, thereby helping the spoiler 2 to better reduce the wind resistance coefficient. But it is not limited to this.

[0041] Computational fluid dynamics (CFD) simulations were performed to compare the protection device 1 with and without spoilers 2, and the following results were obtained: Figure 4The analysis principle diagram shown in FIG. In which, the vehicles are traveling at the same speed and at the same position (such as Figure 4 The airflow height with the spoiler 2 is less than the airflow height without the spoiler, that is, the wind resistance can be reduced by installing the spoiler 2. Calculations were made accordingly, as shown in Table 1 below. After the spoiler 2 was installed on the protective device 1, the drag coefficient was estimated to be reduced to 13 count, and the drag coefficient value was estimated to be reduced by 2.45%.

In addition, the vehicle's passability is also improved.

[0046] According to some embodiments of the utility model, the vehicle further includes a chassis (not shown), and the connecting bracket 4 of the spoiler structure 100 is connected to the front end of the chassis. For example, the connecting bracket 4 is connected to the front end of the chassis corresponding to the bottom of the front of the vehicle. As a result, when the airflow passes through the bottom of the vehicle during driving, the spoiler structure 100 plays a spoiler role, which can effectively reduce the wind resistance coefficient of the vehicle. In addition, it is also convenient to connect the spoiler structure 100 to the chassis.

[0047] According to other embodiments of the utility model, the vehicle further includes a bumper (not shown), and the connecting bracket 4 of the spoiler structure 100 is connected to the bumper.
