Detailed Description
In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.
As shown in fig. 1, an adjustable wind guiding and noise reducing device 1 is disposed between a fan module 2 and a hard disk module 3.
As shown in fig. 2, an adjustable wind guiding and noise reducing device 1 includes a fixed frame 11, and a plurality of wind guiding mechanisms 12 are disposed on the fixed frame 11 along a length direction. As a specific implementation manner, the fixed frame 11 in this embodiment is a square frame formed by connecting four flat plates end to end in sequence.
As shown in fig. 2 and 3, the left side plate and the right side plate of the fixing frame 11 are respectively fixedly connected to the chassis by screws. The upper side plate and the lower side plate of the fixed frame 11 are respectively provided with an upper chute 111 and a lower chute 112 arranged along the length direction.
As shown in fig. 3 and 4, the air guiding mechanism 12 includes a central shaft 121 disposed between the upper side plate and the lower side plate, and an upper end and a lower end of the central shaft 121 extend to the outside of the fixed frame 11 through the upper chute 111 and the lower chute 112, respectively. The central shaft 121 is sleeved with an air guide strip 122 inside the fixed frame 11 (i.e., between the upper side plate and the lower side plate), and the central shaft 121 can drive the air guide strip 122 to rotate. As shown in fig. 8, a stopper 123 for limiting the upward movement of the central shaft 121 in the axial direction is disposed at the lower end of the central shaft 121 outside the fixed frame 11 (i.e., below the lower side plate), and preferably, the stopper 123 has a circular cross section. The upper end of the center shaft 121 is provided at the outside of the frame with a first locking nut 124 for locking the center shaft 121.
Further, in order to quantitatively adjust the position of the air guiding mechanism 12, as shown in fig. 3 and 4, a position indicating plate 125 is sleeved on the central shaft 121 between the first locking nut 124 and the upper side plate, a first through hole 1252 for accommodating the central shaft 121 is provided on the position indicating plate 125, and a first scale 113 for indicating a position is provided on the upper side plate.
Further, as shown in fig. 5, a sliding block 1251 matched with the upper sliding groove 111 is disposed on the lower side surface of the position indication plate 125, and as a specific implementation, the length of the sliding block 1251 is the same as that of the position indication plate 125 in this embodiment.
Further, in order to read the position of the air guiding mechanism 12 more intuitively and facilitate observation, as shown in fig. 4 and 5, a square notch 1253 is disposed at a position on the position indicating plate 125 corresponding to the first scale 113, and one side surface of the notch 1253 is perpendicular to the front side surface of the upper side plate, for convenience of description, a side surface of the notch 1253 perpendicular to the front side surface of the upper side plate is defined as an indicating surface, and the rotation axis of the central shaft 121 is located in the indicating surface.
Further, in order to facilitate quantitative adjustment of the angle of the wind guide strip 122, as shown in fig. 5, 6 and 7, an annular angle indicator plate 126 is sleeved between the first locking nut 124 and the position indicator plate 125 on the central shaft 121, a positioning protrusion 1261 is disposed on an inner arc surface of the angle indicator plate 126, and a positioning groove 1211 matched with the positioning protrusion 1261 is disposed on a portion of the central shaft 121 located above the wind guide strip 122. The rotation between the angle indicating plate 126 and the center shaft 121 is restricted by the positioning protrusion 1261 and the positioning groove 1211. A second scale 1254 for indicating an angle is disposed on the position indicating plate 125 and located outside the angle indicating plate 126, and a pointer 1262 used in cooperation with the second scale 1254 is disposed on the angle indicating plate 126.
When adjusting the position of the air guiding mechanism 12 and the angle of the air guiding strip 122, the first lock nut 124 is first loosened, and then the central shaft 121 is slid along the upper chute 111 and the lower chute 112 until the central shaft moves to a predetermined position. Then, the position indicator plate 125 is pressed, the position indicator plate 125 is kept still, and then the angle of the wind guide strip 122 is adjusted. After the angle adjustment of the air guide bar 122 is completed, the position indicator plate 125 and the air guide bar 122 are simultaneously pressed, the position indicator plate 125 and the air guide bar 122 are kept still, and then the first locking nut 124 is screwed.
As can be seen from the above working process, when the first locking nut 124 is finally tightened, the position indicator 125 and the wind guide strip 122 need to be pressed at the same time, which causes inconvenience in operation.
As shown in fig. 4 and 5, a clamping plate 127 is sleeved on the central shaft 121 between the upper side plate and the air guide strips 122, and the clamping plate 127 is provided with a second through hole for accommodating the central shaft 121. Guide posts 1271 are respectively arranged on two sides of the second through hole on the clamping plate 127, guide holes 1255 matched with the guide posts 1271 are arranged on the position indicating plate 125, and preferably, the guide posts 1271 are matched with the guide holes 1255 after passing through the upper chute 111. The guiding post 1271 is provided with a second locking nut 128 for locking the clamping plate 127 and the position indicating plate 125.
Thus, after the position of the air guiding mechanism 12 is adjusted, the position of the central shaft 121 can be fixed by the clamping plate 127 and the second locking nut 128, and then the angle of the air guiding strip 122 is adjusted, and after the position is adjusted, only the air guiding strip 122 needs to be held. The first lock nut 124 is then tightened.
The reason why the quantitative adjustment of the air guiding mechanism 12 is required is that there is always a position and an angle that can achieve better reading and writing performance of the hard disk, and if the position and the angle are repeatedly implemented, quantitative adjustment is required, and manual visual observation cannot be carried out.
Further, in order to reduce the wind flow loss, as shown in fig. 8, the cross section of the wind guide strip 122 is elliptical.
Further, in order to achieve a certain noise reduction effect, the air guide strip 122 is made of sound-absorbing foam.
The foregoing is only a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the invention, and such modifications and improvements are also considered to be within the scope of the invention.
