Description

Casing (CN)

Technical Field

The invention relates to a casing, in particular to a casing capable of accommodating power supplies with different sizes.

Background

Generally, a power supply is provided in a server to convert ac power from a power source into low-voltage stable dc power, so as to provide power required by each electronic component in the server. In order to stably accommodate the power supply in the server, the server casing includes a fixing structure for fixing the power supply.

However, power supplies with different specifications have different sizes, for example, the power supply with higher power generally has a larger size, but the fixing structure of the conventional server chassis for the power supply can only match with the power supply with one size, so that the conventional server chassis needs to provide a dedicated fixing structure for the power supplies with different sizes. Therefore, the production cost of the server shell is increased.

Disclosure of Invention

The present invention provides a housing to avoid the problem of increasing the manufacturing cost of the housing due to the need of providing a dedicated fixing structure for power supplies with different sizes in the conventional housing.

The casing disclosed in an embodiment of the present invention is used to accommodate a first power supply or a second power supply, wherein the size of the first power supply is larger than that of the second power supply, and two opposite sides of the first power supply are respectively provided with a groove. The casing comprises a bottom plate, a protruding structure, a power supply fixing frame and a mounting sheet. The protruding structure protrudes out of the bottom plate. The power supply fixing frame is arranged on the bottom plate. The power fixing frame and the bottom plate together form a containing groove. The protruding structure is located in the containing groove. The mounting piece is fixed in the power mount and keeps away from one side of bottom plate, and the mounting piece is arranged in the storage tank. When the accommodating groove is used for accommodating the first power supply, the protruding structure and the mounting piece are respectively positioned in the two grooves of the first power supply. When the accommodating groove is used for accommodating the second power supply, the protruding structure and the mounting piece are abutted against one side of the second power supply.

According to the casing disclosed in the above embodiment, since the protruding structure and the mounting piece of the bottom plate can be respectively located in the two grooves of the first power supply when the accommodating groove accommodates the first power supply, and can abut against one side of the second power supply when the accommodating groove accommodates the second power supply, the casing can fix the power supplies of different sizes only through the power fixing frame of a single specification. Therefore, the invention can improve the flexibility of the casing matched with the power supply, thereby reducing the inventory pressure of the casing.

The foregoing summary of the invention, as well as the following detailed description of the embodiments, is provided to illustrate and explain the principles and spirit of the invention, and to provide further explanation of the invention as claimed.

The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

Please refer to fig. 1 to 3. Fig. 1 is a partially enlarged perspective view of a chassis with a first power supply according to a first embodiment of the invention. Fig. 2 is a partially enlarged perspective view of the case provided with the second power supply according to the first embodiment of the invention. Fig. 3 is a partially enlarged perspective view of a cabinet according to a first embodiment of the present invention.

The housing 10 of the present embodiment is used for accommodating a first power supply 20 (as shown in fig. 1) or a second power supply 30 (as shown in fig. 2). The structure of the housing 10 is described first, and the relative position relationship and operation manner when the housing 10 accommodates the first power supply 20 and the second power supply 30 are described in detail after the structure of the housing 10 is described.

As shown in fig. 3, the housing 10 of the present embodiment includes a bottom plate 100, a plurality of protruding structures 150, a side plate 200, a power fixing frame 300, and a mounting plate 400. These protruding structures 150 protrude from the base plate 100. For example, the protruding structures 150 and the bottom plate 100 are integrally formed and the protruding structures 150 are made by stamping, but the invention is not limited thereto, and in other embodiments, the protruding structures and the bottom plate may be a combined structure.

In addition, the number of the protruding structures 150 is not limited to the invention, and in other embodiments, the housing may include only one protruding structure.

The side plate 200 stands on one side of the bottom plate 100 and forms an installation space 250 together with the bottom plate 100. The mounting space 250 may be used to accommodate the power supply holder 300 and other electronic components disposed in the casing 10.

The power holder 300 is disposed in the installation space 250, and the side plate 200 and the power holder 300 are disposed on the same side of the bottom plate 100. The power holder 300 includes, for example, a top cover 301, a first sidewall 302 and a second sidewall 303. The top cover 301 has a mounting groove 3010, and the mounting groove 3010 is communicated with the accommodating groove 500. The first sidewall 302 and the second sidewall 303 stand on the top cover 301 and keep a distance D therebetween. The interval D is determined according to the size of the first power supply 20, for example. The first side wall 302 and the second side wall 303 stand on the bottom plate 100 and are parallel to the side plates 200. The top cover 301 covers the first sidewall 302 and the second sidewall 303 away from the bottom plate 100. In addition, the second sidewall 303 has a locking slot 3030. Furthermore, the top cover 301, the first sidewall 302, the second sidewall 303 and the bottom plate 100 together surround to form a receiving cavity 500. The receiving groove 500 may be used for receiving one of the first power supply 20 and the second power supply 30. The protrusion structure 150 is located in the receiving groove 500.

The structure of the power holder 300 is not intended to limit the present invention, that is, in other embodiments, the power holder may only include a top cover standing on the side plate of the housing. In still other embodiments, the second sidewall may be a portion of the side plate. In other words, part of the side plate stands on one side of the top cover. In the first embodiment of the present invention, the number of the power holders 300 is one, but not limited thereto. In other embodiments of the present invention, more than two power holders may be disposed on the bottom plate 100 to accommodate more than two power supplies with the same or different sizes.

Please refer to fig. 3 and 4. Fig. 4 is a perspective view of a mounting tab of the chassis of fig. 3. The mounting piece 400 is fixed to the top cover 301, for example, and is combined with the top cover 301, for example, and in detail, the mounting piece 400 includes a protrusion 401 and two latching portions 402. Two latch portions 402 are connected to opposite sides of the protrusion 401. The two engaging portions 402 are engaged with the top cover 301. The protrusion 401 passes through the mounting groove 3010, and a part of the protrusion 401 is located in the receiving groove 500. In other embodiments, the top cover does not need to have the mounting groove, and the mounting piece is directly mounted on one side of the top cover close to the bottom plate.

Further, the rigidity of the mounting plate 400 is, for example, greater than that of the projection structure 150, and in detail, in the present embodiment, the Young's modulus (Young's modulus) of the material of which the mounting plate 400 is made is greater than that of the material of which the projection structure 150 is made. Referring to fig. 5, fig. 5 is a partially enlarged view of a cross-sectional view of the housing of fig. 1 when the first power supply is installed. The width W1 of the mounting piece 400 in the direction in which it extends toward the side plate 200 is greater than the width W2 of each of the projection structures 150 in the direction in which it extends toward the side plate 200.

Since the chassis with the power supply device is required to be subjected to the drop test, the power supply device is prevented from being displaced due to general impact, and further, the power supply device cannot normally supply power to other electronic components (not shown), so that the rigidity of the mounting sheet 400 is enhanced in this embodiment, and the power supply device in the chassis 10 is prevented from being displaced during the drop test, and is subjected to the drop test. That is, the rigidity of the mounting piece 400 is improved and is less likely to be deformed by a general impact. As a result, when the housing 10 is impacted, the first power supply 20 (as shown in fig. 1) or the second power supply 30 (as shown in fig. 2) is prevented from moving, so that the first power supply 20 (as shown in fig. 1) or the second power supply 30 (as shown in fig. 2) is prevented from being electrically connected to other electronic components after the impact, and power can be continuously provided to other electronic components.

In the present embodiment, the rigidity of the mounting piece 400 is enhanced to pass the drop test, but the present invention is not limited thereto. In other embodiments, the protruding structure may be made of a material having a larger young's modulus or the width of the protruding structure may be widened in order to pass the drop test, thereby increasing the rigidity of the protruding structure, or both the mounting plate and the protruding structure may be reinforced in order to pass the drop test.

In the present embodiment, the rigidity of the mounting plate 400 is made greater than the rigidity of the protruding structure 150 by using the difference in material and structure, but the present invention is not limited thereto, and the rigidity of the mounting plate may be made greater than the rigidity of the protruding structure only by the difference in material or structure. In other words, in other embodiments, the mounting plate and the protruding structure may have the same width and be made of a material with greater rigidity, or the mounting plate and the protruding structure may be made of the same material and have a greater width and greater rigidity.

Please refer to fig. 5 to 8. Fig. 6 is a partially enlarged perspective view of the housing and the first power supply of fig. 1. Fig. 7 is a partially enlarged view of a cross-sectional view of the case of fig. 2 with the second power supply installed. Fig. 8 is a partially enlarged perspective view of the housing and the second power supply of fig. 2.

For example, the width W3 of the first power supply 20 is greater than the width W4 of the second power supply 30, and two opposite sides of the first power supply 20 respectively have a groove 21.

When the accommodating groove 500 accommodates the first power supply 20, a locking spring 22 of the first power supply 20 is locked in the locking groove 3030 (as shown in fig. 1), and the protruding structures 150 and the mounting pieces 400 are respectively located in the two grooves 21 of the first power supply 20. In this way, the first power supply 20 can be stably fixed in the receiving groove 500. In addition, the protruding structures 150 and the mounting pieces 400 can guide the first power supply 20 through the two grooves 21, so that the first power supply 20 is inserted into the receiving groove 500 more smoothly.

When the snap spring 22 is pressed to disengage from the snap groove 3030, the first power supply 20 can be removed from the receiving groove 500 by the guidance of the protruding structures 150 and the mounting plate 400.

When the receiving groove 500 receives the second power supply 30, a locking spring 31 of the second power supply 30 is locked in the locking groove 3030 (as shown in fig. 2), and the protruding structures 150 and the mounting plate 400 are abutted against one side of the second power supply 30 away from the side plate 200. In addition, the second power supply 30 can be guided by abutting against the protruding structures 150 and the mounting pieces 400 of the second power supply 30, and then can be inserted into the receiving groove 500 more smoothly.

When the snap spring 31 is pressed to disengage from the snap groove 3030, the second power supply 30 can be more smoothly removed from the receiving groove 500 by the guidance of the protruding structures 150 and the mounting pieces 400.

The invention is not limited to the position of the protruding structures 150 and the mounting pieces 400 abutting against the second power supply 30, and in other embodiments, the protruding structures and the mounting pieces may abut against the side of the second power supply close to the side plate in cooperation with the arrangement in the chassis.

In the first embodiment, the rigidity of the mounting piece 400 is enhanced by increasing the width, but the invention is not limited thereto. Referring to fig. 9, fig. 9 is a partially enlarged cross-sectional view of a case provided with a second power supply according to a second embodiment of the invention. In this embodiment, the mounting plate 400a and the protruding structure 150a are made of the same material. Thickness T1 of mounting tab 400a may be greater than thickness T2 of each projecting structure 150a, such that the rigidity of mounting tab 400a is greater than the rigidity of projecting structure 150 a. Here, the outer shape of protruding structure 150a exhibits an arch bridge shape, and thickness T2 of protruding structure 150a represents the thickness of protruding structure 150a itself, and is not the farthest distance of protruding structure 150a from bottom plate 100 a.

In addition, because the rigidity of the mounting sheet is greater than that of the protruding structure, the mounting sheet can have a better result in a drop test without being deformed by a common impact. Therefore, the power supply can be stably installed in the casing, and the chance that the power supply function of the power supply is affected by the impact of external force can be reduced.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
