Description

Technical Field

[0001] The utility model relates to the technical field of automobile exterior panels, in particular to an active heat dissipation spoiler mechanism. Background Art

[0002] Current new energy vehicles generally suffer from insufficient cabin heat dissipation. This is due to the fact that the cabin's air conditioning system and powertrain generate a lot of heat during operation. Furthermore, the increasing number of closed front fascias in current vehicle exteriors has resulted in a more enclosed front cabin than in traditional fuel vehicles. As more new energy vehicles pursue driving performance, the heat generated by the motors and brakes during operation is also increasing. Furthermore, some new energy vehicles are equipped with a reverse charging function, which causes significant heat to be generated within the vehicle during battery charging and discharging.

[0044] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0045] like Figure 1 and Figure 2 , which is a structural diagram of an embodiment of the present invention, provides an active heat dissipation spoiler mechanism, including a mounting frame 1, a cover plate 2, a drive motor 3, a drive connecting rod assembly 4 and a driven connecting rod assembly.

[0046] The mounting bracket 1 is fixed on the vehicle body, such as the inner side of the bumper, and is used for mounting the driving motor 3 and connecting with the driven connecting rod assembly.

[0047] The cover plate 2 is movably mounted on the vehicle body and comprises an outer plate 2-1 and an inner plate 2-2 fixedly connected to the outer plate 2-1. The cover plate 2 can be moved or reset to the outside of the vehicle exterior panel under the drive of the driving motor 3.

[0048] The drive motor 3 is mounted on the mounting frame 1 , and the cover plate 2 is connected to the drive motor 3 and driven by the drive motor 3 to move closer to or away from the vehicle body to close or open the vehicle body, thereby facilitating heat dissipation of the vehicle body.

[0049] The driving connecting rod assembly 4 has a first end connected to the power output end of the driving motor 3 and a second end rotatably connected to the inner plate 2-2.

[0050] Specifically, the driving link assembly 4 includes a main body 4-1, two first driving links 4-2 formed at the first end of the main body 4-1, and two second driving links 4-3 formed at the second end of the main body 4-1, wherein the two first driving links 4-2 are connected to the driving motor 3 via the spline shaft 7, and the rotating shafts 4-3a at the ends of the two second driving links 4-3 are rotatably connected to the inner plate 2-2. The structure of the driving link assembly 4 can improve the strength and stability of the structure.

[0051] like Figures 3 to 8As shown, in order to facilitate the installation of the drive link assembly 4, a mounting seat for mounting two second drive links 4-3 is provided on the inner side of the inner plate 2-2, and the mounting seat includes two rotating seats 2-2a arranged opposite to each other for the rotating shaft 4-3a to pass through, a slot 2-2a1 for the rotating shaft 4-3a to be placed in the inner side of the rotating seat 2-2a is provided, and a limiting portion 2-2a2 for limiting the escape of the rotating shaft 4-3a is provided on the outer side, the limiting portion 2-2a2 has an axial hole for the rotating shaft 4-3a to pass through and partially covers the rotating shaft 4-3a to prevent the rotating shaft 4-3a from escaping.

[0052] When the driving connecting rod assembly 4 rotates to a certain angle, in order to prevent axial movement between the driving connecting rod assembly 4 and the inner plate 2-2, a limiting rib 2-2b is connected between the two rotating seats 2-2a.

[0053] In this example, the first drive link 4-2 and the second drive link 4-3 are connected to the main body 4-1 at an angle and are bent toward the middle of the main body 4-1. This structure facilitates the drive motor 3 to drive the cover plate 2 to move toward the outside of the vehicle body.

[0054] In order to further optimize the implementation effect of the present invention, a pressure plate component 6 is also provided. The pressure plate component 6 is fixed on the mounting frame 1 and is covered on the side of the first end of the driving connecting rod assembly 4 away from the cover plate 2. It can play a role in limiting and tightening, and avoid radial movement between the driving connecting rod assembly 4 and the spline shaft 7.

[0055] The driven connecting rod assembly includes two driven connecting rods 5 arranged on both sides of the driving connecting rod assembly 4. The provision of two driven connecting rods 5 can improve the stability of the structure.

[0056] In order to facilitate the installation of the driven connecting rod 5, two relatively arranged hinged seats 2-2c for installing the two driven connecting rods 5 are provided on the inner side of the inner plate 2-2. The first end of the driven connecting rod 5 is rotatably connected to the mounting frame 1 via the first pin shaft 8, and the second end of the driven connecting rod 5 is rotatably connected to the hinged seat 2-2c via the second pin shaft 9. The first pin shaft 8 and the second pin shaft 9 are limited by pin shaft retaining rings.

[0057] The working principle of this utility model is:

[0058] When the body needs to be cooled, the driving motor 3 drives the driving link assembly 4 to rotate, driving the cover plate 2 to move outward away from the body, and air flows in through the opening between the cover plate 2 and the body to cool the body.

[0059] When the cover 2 is set to open inward, the front windward area can be reduced, the wind resistance can be reduced, the airflow direction can be changed, and the airflow can be guided toward the side of the vehicle body to achieve the effect of spoiler.

[0060] In summary, the heat dissipation and spoiler mechanism facilitates heat dissipation and spoilering of the vehicle body, has a simple structure and is easy to operate.

[0061] The above examples are intended only to illustrate the technical concepts and features of this utility model. Their purpose is to enable those familiar with the art to understand the content of this utility model and implement it accordingly. They are not intended to limit the scope of protection of this utility model. Any equivalent changes or modifications based on the spirit of this utility model shall be included in the scope of protection of this utility model.
