Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to a reflective light-emitting external active intake grille. Background Art

[0002] With the development of the electrification of the automotive industry, consumers have higher and higher requirements for the ride comfort, vehicle networking intelligence and appearance personalization of automobiles. The heat dissipation functional requirement of the automobile grille is gradually reduced, the grille opening is getting smaller and smaller, and the proportion of the decorative requirement is getting higher and higher. The existing intake grilles usually include a fixed decorative grille and an active intake grille. Among them, the fixed grille only plays a decorative role, and the intake air volume cannot be adjusted. In order to meet the requirements of vehicle air intake and heat dissipation functions, some automobiles use active intake grilles, but this functional grille is actually a traditional built-in grille, which is hidden inside the vehicle body, and it still cannot take into account the aesthetic and aerodynamic styling characteristics; even more automobiles completely close the grille in order to reflect the styling appearance elements, resulting in that this grille cannot meet the air intake of the air conditioner and the heat dissipation requirements of the battery and engine of pure electric and hybrid electric vehicles. At the same time, in order to improve the ride comfort inside the vehicle, the NVH sound insulation effect of this part of the vehicle has also been optimized to the extreme, making it relatively difficult to communicate between the inside and outside of the vehicle. In this case, when the automobile is at a traffic intersection with a large and complex traffic flow and pedestrian flow, it becomes a thorny problem to interact with pedestrians in the sealed and sound-insulated vehicle environment to avoid the embarrassment of waiting for courtesy or moving forward together with pedestrians. That is to say, the current intake grilles on the market can only achieve one of the decorative interaction function and the intake heat dissipation function, and cannot meet both at the same time. If visibility is to be demonstrated, the lighting circuit needs to be directly arranged on the blades, but the blades are prone to cause wire harness twisting during movement, and it is also difficult to overcome the problems of waterproofing and dustproofing. If the lighting element is installed on the fixed grille housing, the lighting display area is small, and the required display effect cannot be achieved well. Therefore, researching and developing an intake grille that can not only meet the appearance decoration, but also realize the lighting interaction with pedestrians and control the intake air volume has become a technical problem to be solved at present.

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the Figures 1 - 3 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] The reflective light-emitting external active intake grille includes a reflective light-emitting module. The reflective light-emitting module includes a fixed frame 2, and a blade group is arranged inside the fixed frame 2. The blade group is composed of a plurality of blades 22. Driving frames 3 and decorative panels 1 that match the fixed frame 2 are respectively arranged on both sides of the fixed frame 2. The decorative panel 1 is arranged on the front side of the fixed frame 2, and the driving frame 3 is arranged on the rear side of the fixed frame 2.

[0021] The decorative panel 1 is snap-connected to the edge of the fixed frame 2. The driving frame 3 and the blade group are connected by a connecting member. When the driving frame 3 moves, the blades of the blade group can be rotated to realize the opening and closing with angle change. A light-emitting element 4 is also arranged on the front side of the blade group. The light-emitting element 4 can irradiate the blade surface with divergent light, so that the whole blade is illuminated. The blade can diffusely reflect the light to the front of the vehicle and thus be perceived by the outside world, realizing reflective light emission. To further control the blades to emit light of different colors, the light-emitting element includes light-emitting units with the same number as the blades. By programming the color lighting of each light-emitting unit, the color display of a single blade can be realized.

[0022] In this embodiment, the cross-section of the fixed frame 2 is hexagonal, and the blade group is composed of 6 blades 22, each blade is triangular, and a reflective layer is provided on the surface of the blade 22. The reflective layer can be sprayed by spraying, or blades made of exterior spray-free materials can be used. A snap-in piece 12 is provided at the end of the decorative panel 1, and a card slot 21 is provided on the fixed frame 2. The decorative panel 1 is connected to the fixed frame by being snapped into the card slot 21 by the snap-in piece 12. The light-emitting element 4 is snapped into the center of the decorative panel 1 through the notch 41, and the signal line 42 of the light-emitting element 4 will be connected to the outside of the decorative panel 1. A support rod 11 is provided inside the decorative panel 1 to form a hollow shape, and the shape formed by the surrounding between the support rods 11 is consistent with the shape of the blades.

[0023] A connecting rod 23 is provided at one side of the blade 22 , and a rotating shaft 231 is passed through the connecting rod 23 . The blade 22 is connected to the fixed frame 2 through a rotating shaft clamp 25 on the frame of the fixed frame 2 via the rotating shaft 231 .

[0024] The back of each blade 22 is connected to the driving frame 3 through a connecting rod 5. Specifically, the connecting rod 5 is connected to the ear 24 on the back of the blade, and the other end of the connecting rod 5 is connected to the driving ear 31 placed on the driving frame 3. When the driving frame 3 moves, the connecting rod 5 will be driven to move, thereby driving the blade 22 to flip. The connecting side of the connecting rod 5 and the driving frame is also provided with a hook 52 to prevent slipping. When the connecting rod and the driving frame are assembled, they are clamped with force. The connecting rod 5 is placed in the driving ear 31 through the clamping column 51, and the hook 52 on one side of the clamping column 51 will hook the end face of the driving ear to prevent the connecting rod from slipping.

[0025] In order to ensure the movement trajectory of the fixed frame 2 and to better control the flipping direction of the blades, a sliding shaft 6 is vertically arranged between the fixed frame 2 and the driving frame 3, and a connecting hole 32 is arranged at the end of the driving frame 3. A linear bearing is arranged in the connecting hole 32 to cooperate with the sliding shaft 6. The other end of the sliding shaft 6 is passed through the fixed frame 2, and the driving frame 3 reciprocates back and forth along the fixed frame 2 on the sliding shaft 6.

[0026] The utility model can be increased in a modular form in actual application, and two application forms are used as examples below:

[0027] In one of them, the fixed frame is in a large integral form, and the decorative panel 1 is also in a whole-piece form and is connected to the fixed frame. That is, multiple groups of blade groups are arranged side by side in the fixed frame. One light-emitting element is correspondingly arranged for each blade, and each group of blade groups includes more than one blade. One or more groups of blade groups are correspondingly provided with one driving frame. When the driving frame moves, it will drive one or more groups of blades to move simultaneously. To better flexibly realize the overall opening and closing of the blades and achieve the indicating function, the fixed frame can correspond to the left and right driving frames.

[0028] In another form, it includes a grille main frame, and at least one reflective light-emitting module is arranged side by side in the grille main frame. That is, each reflective light-emitting module is installed on the grille main frame separately.

[0029] Both of the above two forms can achieve synchronous linkage of multiple groups of blades through control. Combined with the light-emitting elements, lights of different colors and brightness can be projected on the blades, realizing interaction with pedestrians or a welcome effect. The structure in the present utility model makes the light-emitting effect more controllable, can achieve richer light effects, and is not restricted by the movement of the blades. At the same time, the fixed position of the lighting element has no movement wear, improving the service life.
