Description

Servo device

Technical Field

The present disclosure relates to servo devices, and particularly to a servo device with a rotary mounting frame.

Background

The world is now in an age of high-speed development of information technology, and personal computers (such as desktop computers and notebook computers) have been used for transactions, whether it be enterprises or individuals. However, as communication technologies mature, transnational electronic commerce has become a trend to replace traditional regional business models. Thus, a typical personal computer cannot meet the needs of an enterprise in a mall. Therefore, computer manufacturers develop servers (e.g., rack server, blade server, or vertical server) in various forms to solve the electronic problem of each enterprise.

At present, a server for storage is generally provided with a plurality of rows of hard disks, and the plurality of rows of hard disks are sequentially arranged from the outside to the inside. For the outermost hard disk, an operator can directly insert and withdraw the hard disk outside the server, but since the inner hard disk is blocked by the outermost hard disk, the operator needs to pull out the tray of the server first and then manually lift the inner hard disk frame.

However, since the wires are generally suspended in front of the server and the space inside the server is relatively crowded, the operator is limited in space and it is difficult to lift the inner hard disk rack.

Disclosure of Invention

The invention aims to provide a servo device for optimizing the process of hard disk replacement.

The disclosed servo device is used for installing an expansion device. The servo device comprises a case, a bearing box, a mounting rack and a rod piece. The case comprises a case body and at least one first stop structure. At least one first stop structure is fixed on the box body. The bearing box is slidably arranged on the box body. The mounting frame is used for mounting the expansion device and is pivoted on the bearing box to be positioned at a flat position or an inclined position. One end of the rod piece is pivoted on the mounting frame, and the other end of the rod piece is provided with a second stop structure. The bearing box can slide relative to the chassis and is positioned at a retracting position, a first pulling-out position or a second pulling-out position. When the bearing box is located at the retracted position, the second stop structure is separated from the first stop structure, and the mounting frame is located at the flat position. When the carrying case moves outwards from the retracted position to the first pulled-out position, the second stop structure abuts against the first stop structure and the mounting frame is located at the flat position. When the carrying case moves outwards from the first pulling-out position to the second pulling-out position, the second stop structure is abutted against the first stop structure, and the mounting frame is pulled by the carrying case and the rod piece to rotate to the inclined position.

In another embodiment of the present invention, a server is disclosed for installing an expansion device. The servo device comprises a case, a bearing box, a mounting rack and a rod piece. The bearing box is slidably arranged on the chassis. The mounting frame is used for mounting the expansion device and is pivoted on the bearing box to be positioned at a flat position or an inclined position. The mounting frame comprises at least one first stop structure. One end of the rod piece is pivoted to the case, and the other end of the rod piece is provided with a second stop structure. The bearing box can slide relative to the chassis and is positioned at a retracting position, a first pulling-out position or a second pulling-out position. When the bearing box is located at the retracted position, the second stop structure is far away from the first stop structure, and the mounting frame is located at the flat position. When the carrying case moves outwards from the retracted position to the first pulled-out position, the second stop structure abuts against the first stop structure and the mounting frame is located at the flat position. When the carrying case moves outwards from the first pulling-out position to the second pulling-out position, the second stop structure is abutted against the first stop structure, and the mounting frame is pulled by the carrying case and the rod piece to rotate to the inclined position.

According to the servo device of the embodiment, the mounting frame is pivoted at one end of the rod, and the second stop structure at the other end of the rod can determine whether to lean against the first stop structure according to the pulled-out position of the carrying case, so that the mounting frame can be pulled out along with the carrying case in the pulled-out process of the carrying case, and the mounting frame can be automatically rotated to an inclined position in the pulled-out process of the carrying case due to the pulling of the rod after the second stop structure of the rod pivoted at the mounting frame leans against the first stop structure. Therefore, an operator does not need to manually move the mounting frame to the inclined position, and the process of hard disk replacement can be optimized.

In some embodiments, one end of the rod is pivoted to the chassis, and the second stop structure at the other end of the rod can determine whether to abut against the first stop structure according to the pulled-out position of the carrying case, so that the carrying case is pulled out along with the carrying case, and the mounting frame is automatically rotated to an inclined position in the pulling-out process of the carrying case when the second stop structure of the rod pivoted to the mounting frame abuts against the first stop structure. Therefore, an operator does not need to manually move the mounting frame to the inclined position, and the process of hard disk replacement can be optimized.

The foregoing description of the invention and the following description of embodiments are presented to illustrate and explain the principles of the invention and to provide a further explanation of the invention as claimed.

Please refer to fig. 1 to 4. Fig. 1 is a schematic partial perspective view of a servo device according to a first embodiment of the present invention. Fig. 2 is a perspective view of the carrying case of fig. 1 in a first pulled-out position. Fig. 3 is a perspective view of the carrying case of fig. 1 in a second pulled-out position and the mounting bracket in an inclined position. Fig. 4 is an enlarged partial schematic view of fig. 3.

The server 10 of the present embodiment is used for installing an expansion device 20. The expansion device 20 is, for example, a hard disk. The servo device 10 comprises a chassis 100, a carrying case 200, a mounting frame 300 and two rods 400.

Please refer to fig. 2, 3 and 5. Fig. 5 is a perspective view of the chassis of fig. 1. The case 100 includes a case 110 and two first stop structures 120. The case 110 includes a bottom case 111 and a top cover 112. The top cover 112 is mounted to the bottom case 111. The two first stop structures 120 are, for example, block structures, located on the inner side of the top cover 112, and fixed to opposite sides of the top cover 112 respectively.

In the present embodiment, the number of the first stop structures 120 is two, but not limited thereto. In other embodiments, the number of first stop structures 120 may be only a single.

Please refer to fig. 3, fig. 4 and fig. 6. Fig. 6 is a schematic cross-sectional view of fig. 1. The carrying case 200 is slidably disposed in the chassis 100. In detail, the carrying case 200 includes a tray 210 and a fixing frame 220. The tray 210 includes two side plates 211 and is slidably positioned in the case 110. The fixing frame 220 is located between the two side plates 211, and includes a bottom plate 221 and two side plates 222. The two side plates 222 of the fixing frame 220 are respectively connected to opposite sides of the bottom plate 221 of the fixing frame 220. The bottom plate 221 of the fixing frame 220 is mounted on the tray 210, for example, by screws, and the two side plates 222 of the fixing frame 220 are interposed between the two side plates 211 of the tray 210 and are separated from the two side plates 211 of the tray 210 respectively to form a wire arrangement space S.

In the present embodiment, the reason why the carrying case 200 is divided into the tray 210 and the fixing frame 220 is that the side plate 211 of the tray 210 and the side plate 222 of the fixing frame 220 form the wire arranging space S. The wires may be finished on the one hand and pulled to the wire during rotation of the mount 300 may be avoided on the other hand. However, the separation of the carrying case 200 into the tray 210 and the fixing frame 220 is not a limitation of the present invention, and in other embodiments, the carrying case may not be separated into the tray and the fixing frame.

In the present embodiment, the carrying case 200 further includes two third stop structures 230. The two third stop structures 230 are, for example, block structures, and are respectively mounted on the two side plates 211 of the tray 210. The function of the third stop structure 230 will be described below.

In the present embodiment, the number of the third stop structures 230 is two, but not limited thereto. In other embodiments, the number of third stop structures 230 may be only a single.

Please refer to fig. 7 to 9. Fig. 7 is a perspective view of the fixing frame, the mounting frame and the rod of fig. 1. Fig. 8 is an exploded view of fig. 7. Fig. 9 is a perspective view of the mount of fig. 7 in an inclined position. The servo 10 may also comprise two pivots 350. The mounting frame 300 is used for mounting the expansion device 20, and includes two side plates 310. The two side plates 310 of the mounting frame 300 have a through hole 311, and are respectively mounted on the two side plates 222 of the fixing frame 220 through the pivot 350, so that the mounting frame 300 is pivoted on the side plates 222 of the fixing frame 220 to be able to be located in a flat position (refer to fig. 1 and 7) or an inclined position (refer to fig. 4 and 9).

In this embodiment, the servo device 10 may further include two guide posts 360. The two side plates 310 of the mounting frame 300 each have a guide slot 312. The guide posts 360 are respectively fixed to the two side plates 222 of the fixing frame 220 and are respectively movably located in the two guide slots 312. In this way, the mounting frame 300 can rotate more stably relative to the fixing frame 220 under the guidance of the guide posts 360 and the guide slots 312.

In the present embodiment, the number of the pivot 350 and the guide post 360 is two, but not limited thereto. In other embodiments, the number of the pivot 350 and the guide posts 360 may be single, and the mounting frame is only installed on one side of the fixing frame through the pivot 350 and the guide posts 360.

The opposite ends of each rod 400 have a pivot structure 410 and a second stop structure 420. In detail, the rod 400 of the present embodiment is, for example, curved and includes a first straight rod section 401 and a second straight rod section 402. The second straight bar section 402 is connected to the first straight bar section 401, and the second straight bar section 402 is not parallel to the first straight bar section 401. The pivot structure 410 is located at an end of the first straight bar section 401 away from the second straight bar section 402 and is pivoted to the side plate 310 of the mounting frame 300. The second stopping structure 420 is, for example, a convex column, and is located at an end of the second straight rod section 402 away from the first straight rod section 401, and abuts against a side of the side plate 211 of the tray 210 away from the bottom plate 221 of the fixing frame 220.

The mounting frame 300 is pulled by the carrying case 200 and the rod 400 to rotate relative to the carrying case 200 to be in a flat position (see fig. 1 and 7) or an inclined position (see fig. 4 and 9). The servo 10 may further comprise a reset element 500. The reset member 500 engages the carrying case 200 and the mounting frame 300 and is used to drive the mounting frame 300 to shift to the flat position.

Please refer to fig. 1 to 4, fig. 7 and fig. 9. As shown in fig. 1 and 7, when the carrying case 200 is located at the retracted position, the second stop structure 420 is separated from the first stop structure 120 and the mounting frame 300 is located at the flat position. In addition, the third stopping structure 230 is separated from the second stopping structure 420 to allow the carrying case 200 to be pulled out.

As shown in fig. 2 and 7, when the carrying case 200 moves from the retracted position to the first pulled-out position along the direction a, the second stopping structure 420 abuts against the first stopping structure 120 and the mounting frame 300 is located at the flat position. In addition, the third stopping structure 230 and the second stopping structure 420 remain separated, so that the carrying case 200 can be pulled out.

As shown in fig. 3, 4 and 9, when the carrying case 200 moves from the first pulled-out position to the second pulled-out position along the direction a, the second stop structure 420 abuts against the first stop structure 120 and the mounting frame 300 is rotated to the inclined position along the direction b by the pulling of the carrying case 200 and the rod 400. Furthermore, when the carrying case 200 is located at the second pulled-out position, the third stop structure 230 abuts against the second stop structure 420 to limit the freedom of movement of the carrying case 200 in the direction a. That is, when the carrying case 200 is located at the second pulled-out position, the carrying case 200 cannot be pulled out further along the direction a due to the interference of the third stop structure 230 and the second stop structure 420.

In the present embodiment, when the mounting frame 300 is in the flat position and the inclined position, the first straight bar section 401 is located at a side of the top edge of the mounting frame 300 near the bottom plate 221 of the fixing frame 220. If another servo is placed above the servo 10, the first straight section 401 is located on the side of the top edge of the mounting frame 300 near the bottom plate 221 of the fixing frame 220 to avoid interference with the other servo.

In the servo device 10 of the present embodiment, since the carrying case 200 is pulled out, the mounting frame 300 is pulled out along with the carrying case 200, and when the second stop structure 420 of the lever 400 pivoted to the mounting frame 300 abuts against the first stop structure 120, the mounting frame 300 is pulled by the lever 400 to automatically rotate to the inclined position during the pulling out of the carrying case 200. In this way, the operator does not need to manually move the mounting frame 300 to the inclined position, so that the process of hard disk replacement can be optimized.

Please refer to fig. 10. Fig. 10 is a schematic partial perspective view of a servo device with a hard disk according to a second embodiment of the invention.

The servo device of this embodiment is similar to the servo device 10 of the embodiment of fig. 1, and only differences will be described below. In the present embodiment, the rod 400a is in a straight bar shape, the pivot structure 410a at one end of the rod 400a is pivoted to the mounting frame 300, and the second stop structure 420a at the other end of the rod 400a abuts against the two side plates 211 of the tray 210. The top cover 112a of the chassis 100a has two relief slots 1121a. When the mounting frame 300 is in the inclined position, a portion of the rod 400a is located in the relief slot 1121a, so as to avoid interference between the rod 400a and the top cover 112 a.

Please refer to fig. 11 and 12. FIG. 11 is a side view of a servo device according to a third embodiment of the present invention. Fig. 12 is a side view schematic of the carrying case of fig. 11 in a second pulled-out position and the mounting bracket in an inclined position.

The servo device 10b comprises a chassis 100b, a carrying case 200b, a mounting frame 300b and a rod 400b. The carrying case 200b is slidably disposed in the chassis 100b. The mounting frame 300b is used for installing an expansion device (not shown), and is pivotally arranged on the carrying case 200b to be able to be positioned in a flat position (see fig. 11) or an inclined position (see fig. 12). The mounting frame 300b includes a first stopping structure 310b, and the first stopping structure 310b is, for example, a protruding column. The pivot structure 410b at one end of the lever 400b is pivoted to the chassis 100b. A second stop structure 420b at the other end of the rod 400b is, for example, a hook, and when the carrying case 200b is pulled out along the direction c, the second stop structure 420b hooks the first stop structure 310b of the mounting frame 300 b. In this way, the mounting frame 300b is driven by the carrying case 200b and the rod 400b to rotate to the inclined position along the direction d.

According to the servo device of the above-mentioned embodiments, the mounting frame is pivoted at one end of the rod, and the second stop structure at the other end of the rod can determine whether to abut against the first stop structure according to the pulled-out position of the carrying case, so that the mounting frame can be pulled out along with the carrying case in the pulled-out process of the carrying case, and when the second stop structure of the rod pivoted at the mounting frame abuts against the first stop structure, the mounting frame is pulled by the rod and automatically rotates to the inclined position in the pulled-out process of the carrying case. Therefore, an operator does not need to manually move the mounting frame to the inclined position, and the process of hard disk replacement can be optimized.

Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but rather, may be modified or altered somewhat by persons skilled in the art without departing from the spirit and scope of the invention.
