Description

Technical Field

[0001] This utility model relates to the field of front bumper, specifically a flow-guided lower bumper structure and a front bumper assembly having the flow-guided lower bumper structure. Background Technology

[0002] As cars become more and more common, whether traditional gasoline cars or electric cars, if the energy consumption of a vehicle is reduced, the driving range will increase accordingly. This factor also determines the owner's car usage costs and satisfaction.

[0003] Therefore, vehicle range is receiving increasing attention, and OEMs are trying their best to improve it.

[0004] Implementing energy-saving measures on the front bumper assembly can significantly improve driving range. One way to reduce energy consumption and extend driving range is by reducing wind resistance.

[0005] In the front bumper assembly, wind resistance can be reduced by optimizing the shape or by optimizing the components.

[0006] Conventional designs typically involve placing a deflector or baffle along the lower edge of the front bumper assembly to reduce overall vehicle drag.

[0007] Traditionally, the air deflector and the front bumper body are designed as separate components, such as the front lower air deflector assembly, front bumper assembly, and other information disclosed by the vehicle manufacturer in document 201420575538.0.

[0008] While traditional air deflectors are effective, their separate design from the front bumper body requires subsequent assembly, wasting time.

[0009] In addition, traditional air deflectors are generally a single plate structure, which has a limited airflow guiding effect and cannot effectively reduce the overall vehicle's wind resistance.

[0010] Therefore, in order to solve or improve at least one of the above problems, it is necessary to optimize the design of the existing air deflector or front bumper body. Utility Model Content

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0034] A flow-guiding lower bumper structure includes a lower bumper body 1, which includes a first plate 11 and a second plate 12. The first plate 11 and the second plate 12 are intersecting. The second plate 12 includes a flow guide plate 121 and a connecting plate 122. The flow guide plate 121 is connected to the first plate 11 through the connecting plate 122. The flow guide plate 121 is inclined. In addition to the traditional function of front-end protection and decoration of a vehicle, the flow-guiding lower bumper structure disclosed in this utility model can also play a good role in guiding airflow.

[0035] This utility model uses a guide plate 121 that is set at an angle; it can guide the airflow during vehicle operation, reduce the amount of airflow entering the front compartment of the vehicle, and thus reduce the overall vehicle running resistance.

[0036] The airflow-guiding lower bumper structure disclosed in this utility model essentially changes the traditional front bumper body structure. It is equivalent to the lower part of the front bumper assembly disclosed in this utility model having a certain airflow guiding effect, which plays a very good airflow guiding role and reduces vehicle running resistance.

[0037] At the same time, based on the above design, the amount of airflow entering the front compartment of the vehicle can be reduced, thereby reducing the overall vehicle running resistance.

[0038] In this utility model, the flow-guiding lower bumper structure mainly includes a lower bumper body 1, which is the main structure of the lower bumper structure and also the main structure of the lower end of the front bumper assembly. The lower bumper body 1 includes a first plate 11 and a second plate 12. The first plate 11 and the second plate 12 are intersecting. The first plate 11 is arranged longitudinally and has an overall arc-shaped plate structure. The second plate 12 includes a flow guide plate 121 and a connecting plate 122. The flow guide plate 121 is connected to the first plate 11 through the connecting plate 122. The second plate 12 is mainly arranged laterally. Furthermore, the flow guide plate 121 acts as a flow guide during subsequent use, while the connecting plate 122 acts as a bridge, facilitating the connection between the flow guide plate 121 and the first plate 11.

[0039] In addition, in this utility model, the guide plate 121 is located in the middle region of the second plate 12, and the guide plate 121 is connected to the first plate 11 via the connecting plate 122 on the side close to the first plate 11.

[0040] In addition, the deflector 121 described in this utility model is inclined. The inclined deflector 121 can play a good role in guiding the airflow and facilitates the limitation of the airflow direction when the vehicle is running. In this utility model, by setting the deflector 121 inclined, when the vehicle moves forward, the deflector 121 can guide the airflow to the ground, thereby reducing the excessive wind resistance formed by the airflow entering the front compartment of the vehicle.

[0041] Furthermore, in this utility model, the first plate 11 is an arc-shaped plate structure; based on this setting, it is convenient to place it at the lower front of the vehicle during subsequent use; thus providing excellent wrapping and protection.

[0042] Furthermore, in this utility model, the connection between the first plate 11 and the connecting plate 122 adopts an arc-shaped surface transition; based on this setting, the existence of the edges of the lower bumper body 1 can be reduced, while playing a good guiding role and reducing the overall vehicle running resistance formed by the lower bumper body 1.

[0043] Furthermore, in this utility model, one end of the deflector 121 is connected to the connecting plate 122, and the other end is set away from the first plate 11; the angle between the deflector 121 and the horizontal plane is an acute angle; based on this setting, when the vehicle moves forward in subsequent use, the deflector 121 can guide the airflow to the ground, thereby reducing the excessive wind resistance formed by the airflow entering the front compartment of the vehicle.

[0044] Furthermore, in this utility model, the guide plate 121 is provided with a support block 13, and the support block 13 is provided with mounting holes; in this utility model, the support block 13 plays a good reinforcing role, which is conducive to ensuring the structural strength of the lower bumper body 1. At the same time, the support block 13 serves as a connection point, which facilitates the installation of the lower bumper body 1 on the vehicle and also facilitates the subsequent connection of other external components.

[0045] Furthermore, the guide plate 121 in this utility model is also provided with a material reduction groove 15, which extends from the guide plate 121 into the support block 13; the material reduction groove 15 plays a good role in reducing material and avoiding the weight of the lower body 1; at the same time, the material reduction groove 15 is a groove structure; it is convenient to store fasteners during subsequent use and avoids the fasteners being exposed on the lower body 1.

[0046] Furthermore, in this utility model, the lower protective body 1 is provided with a connecting mechanism 14, which includes a positioning component and a fixing component; the positioning component includes a longitudinal positioning plate 142 disposed on the lower protective body 1; the longitudinal positioning plate 142 is provided with a positioning pin 143; the lower protective body 1 is inserted into the upper protective body through the positioning pin 143; the fixing component includes a lower horizontal support plate 141 disposed on the lower protective body 1; the lower horizontal support plate 141 is provided with a fastening hole; the setting of the connecting mechanism 14 facilitates the subsequent installation connection and installation fixation between the upper protective body and the lower protective body 1.

[0047] The fastening holes facilitate the insertion and fixing of fasteners.

[0048] A front bumper assembly includes an upper bumper body 2 and a flow-guided lower bumper structure; the flow-guided lower bumper structure is connected to the upper bumper body 2 via a connecting mechanism 14.

[0049] In addition, in this utility model, the upper protective body and the lower protective body 1 are connected at both ends by an assembly mechanism; the assembly mechanism facilitates the connection between the upper protective body and the lower protective body 1; in this utility model, the upper protective body 2 and the lower protective body 1 are mainly locked and fixed at both ends, and the middle part is installed by overlapping the front grille.

[0050] The assembly mechanism described in this utility model includes a positioning component and a fixing component; the positioning component and the fixing component are mainly used for the connection between the upper protective body 2 and the lower protective body 1, so as to facilitate the installation and fixing of both ends of the upper protective body 2 and the lower protective body 1.

[0051] Specifically, the positioning component in this utility model includes a longitudinal positioning plate 142 disposed on the lower protective body 1, and a positioning pin 143 disposed on the longitudinal positioning plate 142; at the same time, the upper protective body 2 is provided with a positioning insertion hole in this utility model; the lower protective body 1 is inserted into the positioning insertion hole on the upper protective body 2 through the positioning pin 143; this arrangement facilitates the lateral insertion and positioning of the lower protective body 1 on the upper protective body 2.

[0052] In addition, the fixing component described in this utility model includes a lower horizontal support plate 141 disposed on the lower body 1; an upper horizontal support plate 21 is disposed on the upper body 2, and the upper body 2 is arranged on the lower horizontal support plate 141 on the lower body 1 through the upper horizontal support plate 21; with this arrangement, the lower horizontal support plate 141 supports the upper horizontal support plate 21; the upper body 2 can be erected on the lower body 1; at the same time, the lower body 1 can provide longitudinal support for the upper body 2.

[0053] In addition, in this utility model, the longitudinal positioning plate 142 is arranged along the longitudinal direction of the whole vehicle, and the upper horizontal support plate 21 and the lower horizontal support plate 141 are arranged parallel to the horizontal plane. Based on this design, the relative fixing components between the upper protection body 2 and the lower protection body 1 can be realized in multiple directions, thus better ensuring the stability of the installation between the upper protection body 2 and the lower protection body 1.

[0054] Furthermore, in this utility model, the longitudinal positioning plate 142 and the lower horizontal support plate 141 are staggered; the longitudinal positioning plate 142 is set perpendicular to the lower horizontal support plate 141; based on this setting, the longitudinal positioning plate 142 and the lower horizontal support plate 141 have a certain offset, which facilitates the longitudinal positioning plate 142 to abut against the side of the upper horizontal support plate 21 during subsequent use, thereby realizing the relative position limitation and calibration of the upper protection body 2 and the lower protection body 1.
