Description

Electronic device and its fixing mechanism

This creation is about a kind of fixing mechanism, especially an electronic device and its fixing mechanism.

Generally speaking, the chassis of electronic devices such as computer hosts or servers are equipped with expansion slots, so that operators or users can adapt the required expansion units (such as graphics processor, hard disk or memory) to meet the needs of various cloud services. Body, etc.) join the system. Moreover, based on the considerations of expandability, repair and maintenance, these expansion units can usually be assembled in a frame to form an expansion unit module and then installed in the chassis together. The frame is detachable to facilitate The operator or user can perform the replacement or addition operation by themselves.

In order to prevent the electrical connection of the expansion unit module from being affected by external force, vibration or other factors, the traditional method is to use screws to lock the frame to the chassis to ensure that the expansion unit module does not leave the predetermined position, but the disadvantage is This makes the assembly/disassembly work time-consuming and cumbersome.

For this reason, some companies have abandoned the method of screw-locking the expansion unit module for the convenience and efficiency of the operation, and only limited the expansion unit module by the upper cover of the chassis. Specifically, the opening of the chassis is usually covered with an upper cover. The upper cover is mainly used to enclose internal components such as expansion unit modules in the chassis. For some traditional chassis, the upper cover can also be used. Stopping on the expansion unit module to limit the upward movement range of the expansion unit module, thereby limiting the expansion unit module. However, from some feedbacks in actual use, the limiting effect of the upper cover is not accurate. In the case of only leaning on the upper cover to limit the position, the expansion unit module will still be relatively far away from the slot when subjected to external force. In addition, when the operator uses manpower to assemble the expansion unit module, it often happens that it is not properly docked, and the upper cover cannot reliably press it back into position. In other words, in some cases, the upper cover still cannot avoid the poor contact of the expansion unit module. Although the cumbersome process of screw locking is omitted, it causes doubts about the quality of the contact. Therefore, how to achieve the purpose of reliably fixing the expansion unit modules in a convenient and effective manner is one of the research and development focuses in this field.

In view of this, the present invention provides an electronic device and its fixing mechanism, which can securely stabilize the position of the expansion unit module while taking into account the convenience and efficiency of disassembly and assembly.

According to an embodiment of the present invention, a fixing mechanism disclosed is suitable for fixing the housing to the chassis. The chassis includes a protruding structure. The fixing mechanism includes a rotating part and an abutting part. The rotating part is pivoted on the shell. The abutment piece is pivotally connected to the rotating piece, and is suitable for moving between the first orientation and the second orientation relative to the rotating piece. When the abutting member is located in the first orientation, the abutting member abuts against the protruding structure. When the rotating member is driven to drive the abutting member to move the abutting member from the first orientation to the second orientation, the abutting member releases the protruding structure.

An electronic device disclosed according to another embodiment of the present invention includes a chassis, a casing, and a fixing mechanism. The chassis includes a protruding structure. The shell is detachably arranged on the chassis. The fixing mechanism includes a rotating part and an abutting part. The rotating part is pivoted on the shell. The abutting piece is pivotally connected to the rotating piece. When the shell is installed in the chassis, the abutting piece abuts against the protruding structure to fix the shell on the chassis. When the casing is separated from the chassis, the rotating member is driven to drive the abutting member to release the protruding structure.

Applying the electronic device and its fixing mechanism of this creative embodiment, the fixing mechanism can abut against the protruding structure of the chassis through the abutting member, and indirectly apply the pre-pressure to the housing to stabilize it at the current position. On the other hand, when When trying to take out the shell, the user only needs to drive the rotating part of the fixing mechanism to release the protruding structure of the abutting part and cancel the pre-pressure restricting the shell. It can be seen that the application of the fixing mechanism of this creation can achieve the purpose of fixing the expansion unit module with simple steps without tools, and it takes into account the need for maintaining electrical connections and the convenience and efficiency of operation.

The above description of the disclosure content of this creation and the description of the following implementation manners are used to demonstrate and explain the spirit and principle of this creation, and to provide a further explanation of the scope of patent application of this creation.

FIG. 1 is a three-dimensional exploded schematic diagram showing the electronic device of this creative embodiment, and FIG. 2 is a partial enlarged schematic diagram showing the electronic device of this creative embodiment. It should be noted that, for the purpose of simplicity and ease of viewing, the diagrams are simplified or omitted, such as wiring, fans, hard disk modules, and other frames that are not directly related to the spirit of this creation. Electronic components. In addition, the electronic device of this creative embodiment can be, for example, but not limited to, a server host, and can also be a server host or a computer host in various other forms.

Please refer to Figures 1~2. An embodiment of this creation proposes an electronic device 9 and a fixing mechanism 1. The electronic device 9 can at least include a case 91, a housing 95, a housing 96, an upper cover 93, and A plurality of the aforementioned fixing mechanisms 1. The case 91 refers to a frame structure mainly used for accommodating and carrying various components in the electronic device 9. As shown in the figure, the aforementioned cases 95 and 96 and the fixing mechanism 1 are all accommodated in the case 91.

The housings 95 and 96 are, for example, a riser cage that can be used to install one or more expansion cards (not shown) to join the electronic device 9 system. The housings 95 and 96 can be used with The expansion cards together constitute an expansion unit module. Specifically, the expansion card can comply with the PCI Express specification, and can be inserted into the PCIe slot (not labeled) on the riser card RC in the housing 95 and 96, and the riser board The RC can be docked with expansion slots MS under the casings 95 and 96, whereby the expansion card can be electrically connected to the main board via the adapter board RC. However, this creation is not limited to expansion cards and adapter boards RC, as well as their quantity, type, and specifications. In addition, the housings 95 and 96 can be respectively installed for different or the same type of expansion units, and this creation is not limited to this. In addition, the shells 95 and 96 may have the same or different size specifications, and the present creation is not limited to this.

Generally speaking, the tight contact when the adapter board RC is plugged into the expansion slot MS can fix the shells 95 and 96 in the chassis 91 to a certain extent, but in order to achieve the stability of the electrical connection, other mechanisms are still needed. To further restrict the positions of the shells 95 and 96. For example, as shown in Figure 1, the upper cover 93, the upper cover 93 is detachably covered on the chassis 91, in addition to protecting the components contained in the chassis 91 (such as the housing 95, 96 and the adapter plate on it) RC and expansion cards... etc.), can also be stopped on the shells 95 and 96 to limit the upward movement range of the shells 95 and 96. However, only relying on the upper cover to press down the expansion card frame has a limited effect. From past experience, it can be known that the upper cover cannot, for example, prevent relative displacement of the housing when the chassis is subjected to external force, or it cannot prevent the operator from moving. The housing (expansion card rack body) that is actually installed is pressed into position, that is, the upper cover still cannot avoid poor contact of the expansion unit in some cases.

In order to solve this problem, the present invention utilizes the fixing mechanism 1 respectively arranged on the sides of the casings 95 and 96 to more reliably limit the positions of the casings 95 and 96 on the casing 91, so as to ensure that the casings 95 and 96 can directly The installation and positioning ensure that the required electrical connections can be maintained when the shells 95 and 96 are subjected to vibration or external impact. As shown in the figure, the housings 95 and 96 can be fixed by the same fixing mechanism 1, and the fixing mechanism 1 can be arranged on different sides of the housings 95 and 96. It can be seen that the fixing mechanism 1 proposed in the present creation It can be selectively configured on one side or opposite sides of the shells 95 and 96 according to requirements, and the present creation is not limited to this.

Specifically, the operating member 30 may include a penetration portion 31 and a fixing portion 32. The penetration portion 31 may be, for example, in the form of a flat-head screw. The penetration portion 31 can be movably penetrated on the top plate 952 of the housing 95. The fixing portion 32 can be, for example, in the form of a nut, which can be locked to the thread of the penetration portion 31 to set the penetration portion 31 on the top plate 952. As shown in the figure, one end of the operating member 30 (such as the fixed portion 32) can abut against the end of the rotating member 10 that is relatively far away from the abutting member 20. Therefore, the movement of the operating member 30 can drive the rotating member 10 to drive the abutting member 20. .

In addition, in the present creative embodiment, the fixing mechanism 1 may further include an elastic member 40, which abuts between the rotating member 10 and the housing 95, and can be used to drive the rotating member 10 to rotate in a specific direction, so that the elastic member 40 can be used to rotate in a specific direction. The abutting member 20 is maintained in the first orientation through the rotating member 10. Specifically, the elastic member 40 may be, for example, in the form of a torsion spring. The elastic member 40 is disposed on the rotating member 10, one end of which abuts against the rotating member 10, and the other end of which abuts against the bottom plate of the housing 95 In step 953, an elastic force rotating in a specific direction can be applied to the rotating member 10, so as to drive the abutting member 20 to provide a resisting force to the protruding structure 97, and at the same time, to provide a resisting force to the operating member 30 via the rotating member 10.

In this configuration, as shown in FIG. 5, one end of the rotating member 10 connected to the abutting member 20 can receive a force rotating in the direction D1, so that the abutting member 20 is opposite to the direction D1 relative to one end of the rotating member 10 The force of the rotation in the direction D1' causes the abutment member 20 to move to the first direction to push up against the protruding structure 97, thereby indirectly generating a downward pre-compression on the housing 95, and the housing 95 can be pre-compressed by this And it is firmly maintained at the current position, so as to ensure the electrical connection between the adapter board RC and the expansion slot MS, and thus to ensure the electrical connection quality of the expansion card. At the same time, the other end of the rotating member 10 relative to the abutting member 20 receives a force rotating in the direction D1' to push the operating member 30 upward for a certain distance, but the top plate 952 is provided with a recess where the operating member 30 is connected. Part (not labeled), so that the operating member 30 does not protrude from the entire upper surface of the top plate 952.

In this creative embodiment, the abutting member 20 may also have a recess 22 located at the end of the abutting member 20 relatively far away from the rotating member 10. When the abutting member 20 is in the first orientation and abuts against the protruding structure 97, the protrusion The structure 97 can be positioned at the recess 22 to stabilize the relative positional relationship between the abutting member 20 and the protruding structure 97 when in contact.

Please refer to FIG. 6 to illustrate how to remove the housing 95 from the chassis 91 by operating the fixing mechanism 1. As shown in the figure, when the casing 95 is to be taken out, the user can press down the operating member 30 (for example, in the direction D1), so that the rotating member 10 is connected to the abutting member 20 to rotate in the direction D1', thereby causing the abutment One end of the member 20 relatively far away from the rotating member 10 rotates in the direction D1 to escape from the protruding structure 97 (away from the hole 9511). At that time, the abutting member 20 is in the second position, and the pre-pressure generated by the fixing mechanism 1 on the housing 95 has been cancelled. At this time, the user overcomes the tight contact force of the adapter plate RC inserted in the expansion slot MS. Take the housing 95 and the expansion card on it out of the chassis 91 together.

Next, please refer to FIG. 7 to explain how to install the housing 95 into the chassis 91. As shown in the figure, when the casing 95 is to be put back into the casing 91, the user only needs to place the casing 95 downward in the casing 91. In the process, the abutment member 20 is relatively far away from one end of the rotating member 10. It can abut against the protruding structure 97 and be pushed by the protruding structure 97 to move to the second direction. Specifically, in this creative embodiment, the abutting member 20 may also have a guiding inclined surface 23, which is located at the end of the abutting member 20 relatively far from the rotating member 10 and relative to the aforementioned recess 22, when the housing 95 is lowered When the abutting member 20 abuts against the protruding structure 97 with the guiding inclined surface 23, the component force generated by the protruding structure 97 on the guiding inclined surface 23 can drive the abutting member 20 to move in the second direction. As the housing 95 continues to move down, Understandably, the protruding structure 97 can cross the guiding inclined surface 23 of the abutting member 20. When the protruding structure 97 crosses the guiding inclined surface 23, the abutting member 20 can return to the state shown in FIG. 5 (ie, the first orientation) And the protrusion structure 97 is pressed upward again.

It can be seen from this that the fixing mechanism 1 of this creative embodiment can apply pre-pressure to the housing 95 when it is installed in the chassis 91 to stabilize its position and ensure the electrical connection state of the expansion card. When the housing 95 is to be removed or installed At the same time, the user can complete it only by pressing the fixing mechanism 1 in a single step or by placing the housing 95 homeopathically. The operation steps are simple and no additional hand tools are needed. It can achieve a stable position of the housing 95 while taking into account convenience and efficiency. .

It is supplemented that since the fixing mechanism 1 of this creative embodiment uses the elastic member 40 to press the abutting member 20 against the protruding structure 97, the generated pre-pressure has elasticity, so that the abutting member 20 can be used in various situations. The state of contacting the protruding structure 97 can be maintained under the external force of 5, which ensures the positioning effect of the fixing mechanism 1 on the housing 95.

In addition, since the fixing mechanism 1 is in the shape of a sheet as a whole, it can be configured on the left, right, other sides or multiple sides of the housing 95 or 96 according to design requirements. As shown in FIG. 1, the fixing mechanism 1 is suitable for the housing 95 On the left side, another fixing mechanism 1 of the same design can be applied to the right side of the housing 96, but the protrusion structure 97 matched with the fixing mechanism 1 in the housing 96 can be correspondingly arranged on the inner side of the side wall (not labeled) of the chassis 91 on. It can be seen that the commonality and application flexibility of the fixing mechanism 1 of this creative embodiment are high, and the position can be adjusted according to various actual needs.

The above is just one example of the fixed mechanism of this creation, and this creation is not limited to this. The following will give examples of other embodiments of the fixing mechanism of this creation. However, it should be stated first that for the purpose of brief description, the following embodiments only illustrate the differences.

Thereby, when the elastic member 40 drives the rotating member 10 to rotate in a specific direction (as shown in the direction D1), one end of the connecting member 70 connected to the abutting member 20' can receive a force rotating in the direction D1', so that the abutting member One end of 20 ′ relatively far away from the rotating member 10 generates a force to rotate in the direction D1, so that the end of the abutting member 20 ′ moves to the first direction and presses the protruding structure 97 downward. In another embodiment of the present invention, the abutting member 20' may have a hook 24, which is suitable for hooking the protruding structure 97 when the abutting member 20' is located in the first orientation, so as to be in the left-right direction of the drawing (such as The direction perpendicular to the directions D1 and D1') restricts the housing 95'.

It can be seen that, corresponding to the size or configuration of the applied housing, the number of connecting rods of the fixing mechanism can be increased or decreased to match the position of the protruding structure or adjust the direction of the pre-pressure applied to the protruding structure.
