Description

Side skirt mounting bracket and vehicle TECHNICAL FIELD

[0001] The present application relates to a side skirt mounting bracket and a vehicle, and belongs to the technical field of vehicles. BACKGROUND

[0002] During driving, a large amount of horsepower is needed to overcome air resistance for a vehicle (especially a large transport vehicle such as a trailer, a semitrailer, a truck, a trailer, etc.), and the energy consumption is very large. In order to reduce the air resistance of the vehicle during driving, a flow guide assembly is usually arranged on the vehicle body to achieve the purpose of saving fuel and energy. The side skirt is a commonly used flow guide assembly, and the side skirt also has a certain protective effect. Therefore, the side skirt is widely used on large transport vehicles.

[0003] The side skirt is usually installed on the left and right sides of the lower part of the vehicle through a mounting bracket. There are many structural forms of the mounting bracket at present. The US patent US8177286B discloses a mounting bracket assembly with multiple structural forms. The side skirt in the patent is installed on the I-beam of the transport vehicle chassis through the mounting bracket assembly. The side skirt rotates and forms a certain angle with the ground during driving of the vehicle, so as to reduce air resistance and obtain partial lift for the side skirt, thereby reducing power consumption during driving of the vehicle.

[0004] Based on comprehensive analysis of various factors such as structural characteristics, later installation convenience, and use effect, it can be known that the mounting bracket assembly with a pull spring arranged in the main frame body in the application has a more reasonable structural design than other mounting bracket assemblies, and has higher feasibility in the installation and application of the side skirt. However, the other mounting bracket assembly structures mentioned in the patent have many disadvantages in actual installation and application, which brings inconvenience and even safety hazards to the installation, maintenance, and use of the side skirt. Therefore, the other mounting bracket assembly structures do not have practical application significance.

[0005] However, the mounting bracket assembly with a pull spring arranged in the main frame body still has the following problems in actual application:

[0006] 1. Due to the use of a tension spring design, the main frame needs to have both upper and lower mounting ends. The upper mounting end must be used to assemble the upper end of the tension spring and ensure the relative fixation of the spring's tip with the vehicle's position. To facilitate the assembly of the mounting bracket assembly and subsequent installation on the vehicle, U-bolts are used on the upper mounting end. During installation, the U-bolts pass sequentially through the top of the main frame, the mounting plate with flanges on both sides, and one side flange of the I-beam, and are locked with nuts. As is well known, the I-beam is the load-bearing beam at the bottom of the vehicle, and this installation method will affect the structural stability of the I-beam to some extent. In addition, the mounting bracket assembly is installed on one side flange of the I-beam with U-bolts. During application, this side flange will inevitably bear a greater force, which will lead to uneven stress on the two sides of the I-beam flange, resulting in eccentric loading. This poses a significant safety hazard in actual application.

[0007] 2. The assembly of this type of mounting bracket assembly with built-in tension springs in the main frame is relatively complicated. Currently, it is all assembled manually, which is inefficient and difficult to automate, making it unsuitable for mass production.

[0008] 3. After the side skirt is installed on the vehicle using the mounting bracket assembly, when the side skirt is subjected to external force, it will cause the main frame to rotate. However, during the rotation, the main frame is mainly limited by the two side flanges of the mounting plate above it. The actual rotation trajectory is uncertain. Especially when the vehicle is turning, some main frames will move inward with the side skirt and some main frames will move outward with the side skirt. When the main frame moves outward, the side skirt will obviously increase the overall width of the vehicle body. From the perspective of vehicle safety, this will also pose certain safety hazards. Technical issues

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a side skirt mounting bracket with reasonable structural design and simple assembly. The mounting bracket is more flexible in its installation on the vehicle chassis. It can be directly welded or riveted to the chassis plane of the vehicle, or it can be installed on the I-beam of the vehicle chassis and can effectively reduce the problem of I-beam eccentric load and ensure the structural stability of the vehicle chassis. The present invention also provides a vehicle for side skirt mounting through the mounting bracket. Technical solutions
