[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model relates to a movable louver structure for a graphics card backplate, such as... Figures 1-3 As shown, the graphics card backplate 1 is provided. The backplate 1 has a backplate air vent 11 on its surface. A louver blade 2 is rotatably connected inside the backplate air vent 11. A linear drive mechanism 3 is also provided on the surface of the graphics card backplate 1. The linear drive mechanism 3 drives the louver blade 2 to rotate through a connecting component between its movable end and the back of the louver blade 2, so as to open or close the backplate air vent 11.
[0024] like Figure 4 As shown, the louver blades 2 are provided with connecting shafts 21 at both ends. The inner wall of the back panel air outlet 11 is provided with connecting holes that are adapted to the size and position of the connecting shafts 21. The connecting shafts 21 extend into the connecting holes so that the louver blades 2 are rotatably connected to the back panel air outlet 11.
[0025] like Figure 5 As shown, the linear drive mechanism 3 includes a housing 31 connected to the surface of the graphics card backplate 1, and a linear motor 32 installed inside the housing 31. An opening (not marked in the figure) is provided on one side of the housing 31 for the movable end of the linear motor 32 to move. The movable end of the linear motor 32 extends out of the opening and is connected to the connecting component. When the linear motor 32 is running, its movable end can drive the connecting component to move accordingly.
[0026] like Figures 6-7 As shown, the connecting assembly includes a sliding member 4 fixedly connected to the movable end of the linear drive mechanism 3, a rocker arm 5 rotatably connected to the surface of the sliding member 4 at one end, and a connecting seat 22 fixedly connected to the back of the louver blade 2. The other end of the rocker arm 5 is rotatably connected to the connecting seat 22. A connecting post 42 is provided on the surface of the sliding member 4. The rocker arm 5 is sleeved on the connecting post 42 and rotatably connected to the connecting post 42. A connecting ear 43 is also provided on the sliding member 4. The connecting ear 43 is fitted and fixedly connected to the movable end of the linear drive mechanism 3.
[0027] In practical use, the linear motor 32 drives the sliding member 4 to move linearly through its movable end. Under the action of the rocker arm 5, the connecting seat 22, which is rotatably connected to the rocker arm 5, will push up the louver blades 2 and rotate them along its connecting shaft 21, thereby forming a shape like... Figures 1-2 The backplate exhaust vent 11 shown is in an open or closed state to provide heat dissipation for the graphics card when it is running at high power, and when it is running at low power or stopped, the backplate exhaust vent 11 is closed to reduce the exposure of components, reduce the impact of external forces on them, and improve aesthetics.
[0028] For those skilled in the art, the operation of the linear motor 32 can also be combined with the heat output of the graphics card and the fan speed. When the heat output of the graphics card or the fan speed is high, the linear motor 32 can respond accordingly. When the graphics card temperature is higher or the fan speed is higher, the opening of the louver blades 2 driven by the linear motor 32 is larger to ensure heat dissipation. Conversely, if the graphics card temperature or the fan speed is lower, the opening of the louver blades 2 driven by the linear motor 32 is smaller to achieve automatic adjustment of ventilation.
[0029] Furthermore, in order to improve the sliding stability of the slider 4, a guide post 311 is provided on the same side of the housing 31 where the opening is provided. At least two sets of guide posts 311 are provided at intervals along the moving direction of the moving end of the linear motor 32. Slide grooves 41 are provided at intervals on the surface of the slider 4 and extend along the moving direction of the moving end of the linear drive mechanism 3. The number, position and size of slide grooves 41 correspond one-to-one with the guide posts 311. The guide posts 311 can be slidably inserted into their corresponding slide grooves 41. When the slider 4 follows the moving end of the linear motor 32, under the action of the guide posts 311 and slide grooves 41, the slider 4 can be effectively restricted from deflection, so that it can be stably kept moving in the moving direction of the moving end of the linear motor 32.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
