Technical Field

The present disclosure relates to electronic devices, and particularly to an electronic device including a supporting rod.

Background

Generally, in order to enhance the performance of the server or expand the functions of the server, a host board of the server is provided with a plurality of different electronic components. If the weight of these electronic components is too large and the motherboard and the chassis carrying the motherboard sink, a shaping mold is needed to elastically deform the motherboard and the chassis, so as to restore the motherboard and the chassis to a completely flat state.

However, due to the limitation of the stamping process, it is difficult for the shaping mold to precisely restore the motherboard and the housing to a completely flat state. Therefore, the motherboard and the housing may have errors after being processed by the shaping mold, and further the motherboard and the housing have other components which are difficult to assemble to the server.

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

Please refer to fig. 1 to 4. Fig. 1 is a perspective view of an electronic device according to an embodiment of the invention. Fig. 2 is a partially enlarged view of a front view of the electronic device in fig. 1. Fig. 3 is a perspective view of an adjustment structure of the electronic device in fig. 1. Fig. 4 is an exploded view of the adjustment structure of fig. 3.

In the present embodiment, the electronic device 10 is, for example, a server and includes a housing 100, a circuit board 200, two electronic components 250 and an adjusting structure 300. In the present embodiment, the housing 100 includes a bottom plate 101 and two side plates 102. The base plate 101 includes a bearing surface 1010. The two side plates 102 stand on two opposite sides of the bearing surface 1010 respectively.

The circuit board 200 is disposed on the carrying surface 1010 of the base plate 101. In the present embodiment, the circuit board 200 and the bottom plate 101 are, for example, parallel to each other and spaced apart from each other. In the present embodiment, two electronic components 250 are fixed on a side of the circuit board 200 away from the bottom plate 101 and supported by the circuit board 200.

In the present embodiment, the adjusting structure 300 includes a mounting frame 301, two support rods 302, two fixing members 303, and two nuts 304. In this embodiment, the mounting bracket 301 is fixed to a side of the two side plates 102 away from the bottom plate 101. In the present embodiment, the mounting block 301 includes a bottom surface 3010, a top surface 3011 and two through holes 3012. Bottom surface 3010 and top surface 3011 face away from each other. Two perforations 3012 pass through bottom surface 3010 and top surface 3011. Bottom surface 3010 is also closer to circuit board 200 than top surface 3011. It should be noted that, in other embodiments, the mounting frame may also be fixed to the bottom plate of the casing through the bracket.

The two support rods 302 are spaced apart from each other. In the present embodiment, each of the two support rods 302 includes a first linear portion 3020, a bent portion 3021, and a second linear portion 3022. The two first linear portions 3020 are movably disposed in the two through holes 3012 of the mounting block 301 along the normal direction N of the bearing surface 1010, and each of the first linear portions includes a thread structure 3023. In each of the support rods 302, the bent portion 3021 connects the first linear portion 3020 and the second linear portion 3022, and the extending direction E1 of the first linear portion 3020 is not parallel to the extending direction E2 of the second linear portion 3022. Specifically, in the present embodiment, the extending direction E1 of the first linear portion 3020 and the extending direction E2 of the second linear portion 3022 are perpendicular to each other.

The two mounts 303 each include a mounting hole 3030. One ends of the two second linear portions 3022 away from the bent portion 3021 are respectively fixed to the two mounting holes 3030 of the two fixing members 303. In addition, two fixing members 303 are fixed to the side of the circuit board 200 away from the base plate 101, for example, by Surface-mount technology (SMT). In addition, in the embodiment, an area of the contact surface 3031 of the fixing member 303 contacting the circuit board 200 is, for example, greater than or equal to 100 square millimeters.

It should be noted that, in other embodiments, the fixing member may also be fixed to the side of the circuit board away from the base plate by adhesion or other suitable fixing means. In other embodiments, the fixing member may not include a mounting hole and in such embodiments, the second linear portion may be directly fixed to the outer surface of the fixing member. In addition, in other embodiments, the adjustment structure does not need to include a fixing member and the second linear portion can be directly fixed to the circuit board. In addition, in other embodiments, the area of the contact surface of the fixing member contacting the circuit board may be less than 100 square millimeters, as long as the required bonding strength is achieved.

Two nuts 304 are respectively screwed on the two screw structures 3023 of the two first linear portions 3020 of the two support rods 302 and bear against the top surface 3011 of the mounting bracket 301.

The adjusting structure 300 is used to adjust the distance between at least a portion of the circuit board 200 and the bottom plate 101. Specifically, since the nut 304 is screwed to the thread 3023 of the first linear portion 3020 and is supported on the top surface 3011 of the mounting bracket 301, when the nut 304 is rotated, the first linear portion 3020 moves in the through hole 3012 of the mounting bracket 301 in the normal direction N. Since the second linear portion 3022 is fixed to the circuit board 200 by the fixing member 303, the first linear portion 3020 further pulls up a portion of the circuit board 200 in the normal direction N away from the bottom plate 101. As such, as shown in fig. 2, even though the circuit board 200 needs to support the electronic component 250, the circuit board 200 can still be maintained in a completely flat state with the assistance of the adjusting structure 300. In addition, in the embodiment, the engagement between the nut 304 and the thread structure 3023 of the first straight line portion 3020 can adjust the distance between the end of the first straight line portion 3020 away from the bent portion 3021 and the top surface 3011 of the mounting bracket 301 to be between 5mm and 10mm, for example.

It should be noted that in other embodiments, the mounting frame need not include through holes. In the embodiment where the mounting frame does not include a through hole, the supporting rod can be movably disposed on the mounting frame through the matching slide rail and the sliding block. In other embodiments, the adjusting structure may also include only one supporting rod. In other embodiments, the supporting rod does not need to include a bending portion and a second linear portion, and the other end of the first linear portion is fixed to the circuit board through a fixing member. In other embodiments, the adjusting structure may not include a nut and the first linear portion may not include a threaded structure, and the gear and the tooth adjustment are used instead to adjust the position of the support rod relative to the mounting bracket. In addition, in the embodiment that the supporting rod is movably disposed on the mounting frame through the sliding rail and the sliding block which are matched with each other, the positioning column can be used to position the sliding block at a specific position on the sliding rail.

In an embodiment of the present invention, the server of the present invention may be used for Artificial Intelligence (AI) operation and edge computing (edge computing), and may also be used as a 5G server, a cloud server or a car networking server.

According to the electronic device disclosed in the above embodiment, since one end of the supporting rod is movably disposed on the mounting frame along the normal direction of the bearing surface, and the other end of the supporting rod is fixed to the side of the circuit board away from the bottom plate, the supporting rod can adjust the distance between at least a part of the circuit board and the bottom plate. Therefore, the circuit board and the shell carrying the circuit board can be kept in a completely flat state without the problem of difficult assembly to other elements.
