Example Embodiment

[0024]Example 1

[0025]This embodiment is the best embodiment of the concept of the present invention. The electric adjusting device for the truck air deflector mainly includes a drive assembly 3, a support assembly 2 and a support assembly 1. Among them, the support assembly 2 includes a pair of brackets 21; the support assembly 1 includes a linkage plate 12 for fixing the deflector 4; the drive assembly 3 includes a geared motor 37 limited on one side of the bracket 21, and limited on the bracket 21. The two-way lead screw 34 between the two-way screw 34 and the output end of the reduction motor 37, the two main rods 32 that are arranged in the same direction as the two-way screw 34, the screw nut 342 that is located on both sides of the two-way screw 34 and cooperates with the screw The connecting rod 31 to which the female 342 is hinged is provided with a guide 33 on the main rod 32 that is matched with the nut 342; the other end of the connecting rod 31 is hingedly matched with t...

Example Embodiment

[0029]Example 2

[0030]This embodiment is a sub-optimal embodiment of the inventive concept, and the purpose of setting this embodiment is to expand the protection scope of the present invention as much as possible. On the premise that the same technical problem can be basically solved, the driving assembly 3 in Embodiment 1 is omitted to some extent. Specifically, the coaching rod 35 is omitted, and the structure of the positioning plate 36 is simplified (for example, as long as it can be used for the sliding range of the nut 342 and can be fixed on the two-way screw 34), the original solution The waist round structure is designed to match the coaching rod 35, the figure is omitted. Based on the original intention of the design, those skilled in the art have the motivation to simplify the structure to reduce the manufacturing cost without affecting the running fluency.

Abstract

An electric adjusting device for a truck fairing comprises a driving assembly (3), a bearing assembly (2) and a support assembly (1), and is characterized in that the bearing assembly (2) comprises apair of supports (21); the support assembly (1) comprises a linkage plate (12) used for fixing the fairing (4); the driving assembly (3) comprises a gear motor (37) limited on the support (21) at oneside, a two-way lead screw (34) limited between supports (21) and arranged at the output end of the gear motor (37), one or more main guide rods (32) arranged in the same direction as the two-way leadscrew (34), nuts (342) located at two sides of two-way lead screw (34) respectively and matched with the two-way lead screw (34), a connecting rod (31) hinged to the nuts (342), and a guiding piece (33) arranged on the main guide rod (32) and cooperated with the nuts (342); and the other end of the connecting rod (31) is hinged and matched with a linkage plate (12). The angle of the fairing can be conveniently adjusted according to different working conditions such as different heights of containers or no-load condition of the truck, a good emission reduction effect is achieved, and fuel oilis saved; and after adjustment is stopped, the fairing can be kept at a corresponding angle position.

Description

technical field [0001] The invention belongs to the technical field of truck wind deflector adjustment, and relates to an electric adjustment device for truck wind deflector. Background technique [0002] When the truck is running, the air resistance is proportional to the square of the truck speed. For container trucks that usually run at high speeds, the effect of the shroud directly affects the fuel consumption and economic benefits of the truck. Existing container truck deflectors are generally used at a fixed angle after installation, and generally only have a good drag reduction effect for containers of one height. However, due to different actual needs, the height of the container loaded on the truck will change or the truck is empty. For these cases, the drag reduction effect of the existing shroud will be greatly reduced. Today, with the increasingly strong demand for energy saving and emission reduction, it is necessary to invent an electric device that can easily...
