[0024] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0025] The following refers to Figure 1 and Figure 2Describe the bumper assembly 2 according to an embodiment of the present utility model. The air dam 1 is disposed on the bumper assembly 2.

[0026] As Figure 1 shown, the bumper assembly 2 according to an embodiment of the present utility model includes: a bumper and an air dam 1. The air dam 1 is connected below the bumper, and the trend of the air dam 1 in the width direction is the same as that of the bumper. Such a setting is reasonable and can ensure the integrity of the connection between the bumper and the air dam 1. The air dam 1 includes: a main body portion 10 and a gravity portion 20. The main body portion 10 is the main part of the air dam 1 and can be used to connect and arrange other components. The gravity portion 20 is mainly a structural member for providing gravity.

[0027] As Figure 1 shown, the gravity portion 20 is connected to the lower end of the main body portion 10. First, the gravity portion 20 and the main body portion 10 can be connected to form an integral body, which is convenient for the installation and arrangement of the air dam 1 of the bumper assembly. Moreover, by connecting the gravity portion 20 to the lower end of the main body portion 10, the gravity portion 20 can increase the gravity of the main body portion 10. In other words, a certain vertical force can be provided to the main body portion 10. It can be understood that due to the material problem of the main body portion 10, its stiffness is poor and it is prone to wave deformation in actual working conditions. By increasing a certain vertical force to the main body portion 10, the stiffness of the main body portion 10 can be improved to a certain extent, thereby preventing its wave deformation.

[0028] Therefore, by connecting the gravity portion 20 to the lower end of the main body portion 10, a certain vertical force can be provided to the main body portion 10 by relying on the gravity portion 20, the stiffness of the main body portion 10 can be improved to a certain extent, thereby preventing the air dam 1 from wave deformation, and the integrity of the appearance of the air dam 1 can be improved on the premise of ensuring the passing performance in actual working conditions.

[0029] Specifically, as Figure 1As shown, the cross-sectional shape of the gravity part 20 is one of a rectangle, a triangle, and a water droplet shape. The top end of the gravity part 20 is connected to the main body part 10. The foremost end of the gravity part 20 does not extend beyond the front end of the main body part 10. The lower end of the gravity part 20 is inclined towards the interior of the vehicle. The gravity part 20 can provide a certain vertical force for the main body part 10, and its cross-sectional shape can be any one of a rectangle, a triangle, and a water droplet shape. The structures of the rectangle and the triangle are simple and convenient for processing and setting, while the water droplet shape structure can better provide a downward vertical force. Of course, all of these can prevent the air dam 1 from deforming in waves and improve the integrity of the appearance of the air dam 1 of the bumper assembly on the premise of ensuring the passability under actual working conditions. In addition, the top end of the gravity part 20 is connected to the main body part 10, and the foremost end of the gravity part 20 does not extend beyond the front end of the main body part 10. The lower end of the gravity part 20 is inclined towards the interior of the vehicle. In this way, the overall structure of the gravity part 20 is inclined towards the interior side of the vehicle, so that the center of gravity of the gravity part 20 can be towards the interior side of the vehicle, thereby better improving the stiffness of the main body part 10, preventing it from deforming in waves, and this setting is reasonable, convenient for installation and layout, and can avoid the air dam 1 occupying the space outside the vehicle.

[0030] Among them, as Figure 1 and Figure 2 shown, the main body part 10 includes: a first connection part 100, a second connection part 101, and a flow guiding part 102. The second connection part 101 is connected between the first connection part 100 and the flow guiding part 102. The gravity part 20 is connected to the lower end of the flow guiding part 102. Specifically, both the first connection part 100 and the second connection part 101 can play a connecting role, and the flow guiding part 102 mainly plays a role in guiding the flow. The first connection part 100, the second connection part 101, and the flow guiding part 102 are connected to form the main body part 10. The second connection part 101 is connected between the first connection part 100 and the flow guiding part 102, so that the first connection part 100 and the flow guiding part 102 can form a whole, which is convenient for the installation and setting of the main body part 10.

[0031] It should be noted that both the first connection part 100 and the second connection part 101 are connected to other structures of the bumper assembly 2. Therefore, the first connection part 100 and the second connection part 101 are not easily deformed, while the flow guiding part 102 is not connected to other structures and is prone to wave deformation. Connecting the gravity part 20 to the lower end of the flow guiding part 102, so that the gravity part 20 can provide a certain vertical force for the flow guiding part 102, preventing its wave deformation, and thus ensuring the flow guiding effect of the flow guiding part 102.

[0032] In addition, as Figure 1As shown, the air dam 1 further includes a reinforcing portion 30 disposed on the flow guiding portion 102. The reinforcing portion 30 mainly functions to strengthen, which can improve the structural strength. By disposing the reinforcing portion 30 on the flow guiding portion 102, at this time, the reinforcing portion 30 and the flow guiding portion 102 form an integral body, that is, the reinforcing portion 30 and the main body portion 10 form an integral body, facilitating the installation and setting of the air dam 1 of the bumper assembly. Secondly, by disposing the reinforcing portion 30 on the flow guiding portion 102, the reinforcing member 20 can improve the structural strength of the flow guiding portion 102, preventing the flow guiding portion 102 from deforming in waves, and thus ensuring the flow guiding effect of the flow guiding portion 102.

[0033] Of course, as Figure 1 shown, there are multiple reinforcing portions 30, and the multiple reinforcing portions 30 are spaced apart in the up and down directions. Multiple reinforcing portions 30 can be disposed on the flow guiding portion 102. The multiple reinforcing portions 30 can further improve the structural strength of the flow guiding portion 102, preventing the flow guiding portion 102 from deforming in waves, and thus ensuring the flow guiding effect of the flow guiding portion 102. And the multiple reinforcing portions 30 are spaced apart in the up and down directions, which can avoid interference between the multiple reinforcing portions 30 and at the same time make the distribution range of the multiple reinforcing portions 30 wider, and also improve the structural strength of the flow guiding portion 102 to a certain extent.

[0034] Furthermore, as Figure 1 shown, the main body portion 10, the gravity portion 20 and the reinforcing portion 30 are of an integrally formed structure. That is to say, the gravity portion 20 and the reinforcing portion 30 are all integrated on the main body portion 10, so that the air dam 1 can be formed as an integral structure, making the structure of the air dam 1 more stable and firm, facilitating installation and setting, and only requiring one processing die, which is convenient for production and manufacturing.

[0035] In addition, as Figure 1 shown, the main body portion 10, the gravity portion 20 and the reinforcing portion 30 are all soft plastic parts. Soft plastic parts have the characteristics of easy molding, corrosion resistance, recyclability, energy saving and cost saving. Since the main body portion 10, the gravity portion 20 and the reinforcing portion 30 are all soft plastic parts, the structure of the air dam 1 can better conform to the actual working conditions. In addition, this can also save energy and cost.

[0036] Of course, as Figure 2As shown in the figure, the bumper includes a bumper body 40 and a bumper frame 50, and the main body portion 10 is connected to the bumper body 40 and the bumper frame 50. Specifically, the bumper body 40 is a component of the bumper, and the bumper frame 50 is the main part of the bumper, which can play a role in support and fixation. The air dam 1 can mainly be used for guiding the flow to reduce the air resistance at the bottom of the bumper. The main body portion 10 of the air dam 1 is connected to the bumper body 40 and the bumper frame 50. At this time, the air dam 1, the bumper body 40, and the bumper frame 50 form an integral whole, that is, the air dam 1 and the bumper form an integral whole, which is convenient for the overall installation and setting.

[0037] It should be noted that, as Figure 1 and Figure 2 shown in the figure, the main body portion 10 includes a first connecting portion 100 and a second connecting portion 101. The first connecting portion 100 is connected to the bumper frame 50, and the second connecting portion 101 is connected to the bumper body 40. Both the first connecting portion 100 and the second connecting portion 101 can play a role in connection. Connect the first connecting portion 100 to the bumper frame 50 and the second connecting portion 101 to the bumper body 40. At this time, the main body portion 10 is connected to the bumper frame 50 and the bumper body 40 through the first connecting portion 100 and the second connecting portion 101 respectively. In this way, it is convenient for the connection between the first connecting portion 100 and the bumper frame 50, and between the second connecting portion 101 and the bumper body 40, so as to realize the connection between the air dam 1 and the bumper, and make the setting of the air dam 1 more stable and firm.
