[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0039] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] It should be understood that in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0041] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0042] Currently, PCIE (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) function cards are widely used in PC (Personal Computer) chassis or servers. This function card has a plug-and-play feature and can achieve good system design flexibility.

[0043] However, when using this function card, the gold finger at the bottom is plugged into the connector, which requires a plug-in force of about 90N. For function cards with liquid cooling capabilities, additional liquid cooling connectors are required for plugging. The maximum plug-in force of a pair of liquid cooling connectors is about 100N, and the total plug-in force required is close to 200N. Therefore, it is very difficult to plug and unplug the function card by hand, and using other tools may cause damage to the function card.

[0044] Therefore, the present application provides an installation mechanism, which only requires rotating the operating part so that the lever part can press the device to be connected in different directions, thereby easily realizing the plug-in connection between the function card and the device to be connected, without the need for additional tools, and more labor-saving.

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0046] On the one hand, combined with Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a mounting mechanism 300 suitable for plugging and unplugging the function card 100 and the device 200 to be connected.

[0047] The installation mechanism 300 includes: a connecting body 1 and a handle assembly 2; the connecting body 1 is connected to the function card 100, and the handle assembly 2 includes a handle piece 21, which is rotatably connected to the connecting body 1, and an operating part 211 is provided at one end of the handle piece 21 located at the rotation axis, and a lever part 212 is provided at the other end of the handle piece 21 located at the rotation axis.

[0048] The installation mechanism 300 is configured such that, during the plugging and unplugging process of the function card 100 and the device to be connected 200, the lever portion 212 abuts against the device to be connected 200, the operating portion 211 drives the handle piece 21 to rotate toward the first direction A1, the lever portion 212 presses against the device to be connected 200, the connection body 1 drives the function card 100 to move along the insertion direction B1, the operating portion 211 drives the handle piece 21 to rotate toward the opposite second direction A2, the lever portion 212 reversely presses against the device to be connected 200, and the connection body 1 drives the function card 100 to move along the removal direction B2.

[0049] The installation mechanism 300 of this embodiment is suitable for the plug-in connection between the function card 100 and the device to be connected 200. The connection body 1 in the installation mechanism 300 is used to connect the function card 100. The handle member 21 in the handle assembly 2 is rotatably connected to the connection body 1, and one end of the handle member 21 is an operating part 211, and the other end is a lever part 212; during the plug-in and pull-out process of the function card 100 and the device to be connected 200, by rotating the operating part 211, the lever part 212 can press the device to be connected 200 in different directions, and the lever part 212 is subjected to the reaction force of the device to be connected 200, so that the connection body 1 drives the function card 100 to be inserted into the device to be connected 200, or unplugged from the device to be connected 200. The plug-in and pull-out connection between the function card 100 and the device to be connected 200 does not require additional tools and has the advantage of being more labor-saving.

[0050] In some possible implementations, the distance between the end where the operating part 211 is located and the rotation axis is greater than the distance between the end where the lever part 212 is located and the rotation axis. The handle member 21 can be regarded as a lever mechanism. The lever arm of the operating part 211 is larger, and the lever arm of the lever part 212 is smaller. Therefore, when a smaller force is applied to the operating part 211, a larger force can be generated on the lever part 212, thereby realizing assisted insertion and removal of the function card 100.

[0051] In this embodiment, the function card 100 includes but is not limited to a graphics card (Graphics Card, GC) that can be plugged and unplugged and expanded with the device to be connected 200, a capture card (Capture Card, CC), a storage card (Storage Card, SC), an acceleration card (such as GPU (Graphics Processing Unit) acceleration card, FPGA (Field Programmable Gate Array) acceleration card, etc.), a network card (Network Card, NC), a sound card (Sound Card, SC), a TV card (Tuner Card, TV), a USB expansion card, a card reader card (such as an SD card reader, a flash memory card reader), and the like.

[0054] Through the above arrangement, the function card 100 can be electrically connected to the device 200 to be connected by using the gold finger 3 on the bottom surface 1001, so that data can be transmitted between the function card 100 and the device 200 to be connected. The function card 100 can be connected to the installation mechanism 300 by using the baffle piece 4 on the side surface 1002, so that the function card 100 can use the installation mechanism 300 to achieve tool-free quick plug-in installation.

[0055] Exemplarily, the device to be connected 200 is provided with at least one slot, and at least one golden finger 3 is plugged into at least one slot to realize electrical connection between the function card 100 and the device to be connected 200 .

[0056] In some embodiments, in combination Figure 4As shown, the baffle member 4 includes a baffle body 41 attached to the side surface 1002 of the function card 100, and a baffle ear plate 42 located at one end of the baffle body 41. The connecting body includes a connecting plate portion 12 attached to the baffle body 41, and the connecting plate portion 12 and the baffle body 41 are arranged in a stacked manner and fixedly connected by at least one first connecting screw 13.

[0059] Through the above arrangement, at least a portion of the lever portion 212 is inserted into the first bayonet portion 53. When the operating portion 211 is rotated toward the stationary direction, the first bayonet portion 53 is pressed along the insertion direction B1 or the removal direction B2, and the connecting body 1 is subjected to the reaction force of the first bayonet portion 53, thereby achieving the purpose of driving the functional card 100 to be inserted or removed.

[0060] Combination Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the device to be connected 200 includes a frame member 5 , the frame member 5 is provided with a support portion 51 , the lever portion 212 is provided with a second bayonet portion 2121 , and at least a portion of the support portion 51 is inserted into the second bayonet portion 2121 .

[0061] In this embodiment, the lever portion 212 is provided with a second bayonet portion 2121, and a support portion 51 is provided on the frame member 5 of the device 200 to be connected. By inserting the support portion 51 into the second bayonet portion 2121, the support portion 51 can also exert a force on the connecting body 1, thereby achieving the purpose of driving the functional card 100 to be inserted or removed.

[0062] Combination Figure 6 As shown, in some embodiments, a first pressing portion 2122 is provided on one side of the second bayonet portion 2121, and a second pressing portion 2123 is provided on the other side of the second bayonet portion 2121; the first pressing portion 2122 is located on the side of the support portion 51 facing the insertion direction B1, and the second pressing portion 2123 is located on the side of the support portion 51 facing the extraction direction B2; when the first pressing portion 2122 presses the support portion 51, the function card 100 moves along the insertion direction B1; when the second pressing portion 2123 presses the support portion 51, the function card 100 moves along the extraction direction B2.

[0063] Through the above arrangement, when the operating portion 211 drives the handle 21 to rotate in different directions, the second bayonet portion 2121 can use the first pressing portion 2122 and the second pressing portion 2123 on both sides to press against different sides of the support portion 51, respectively, to achieve the power-assisted insertion and removal of the function card 100. The handle 21 is designed as a two-way lever, which can assist downward when the function card 100 is inserted, and assist upward when the function card 100 is removed.

[0064] Combination Figure 6 As shown, in some embodiments, the frame member 5 includes a step portion 52, the step portion 52 includes a side wall 521 parallel to the insertion direction B1 and a top wall 522 perpendicular to the insertion direction B1, and a avoidance portion 523 is provided at a position of the side wall 521 near the top wall 522, so that at least part of the top wall 522 is suspended up and down to form a support portion 51.

[0065] Through the above arrangement, the step portion 52 on the frame member 5 can be utilized, and the avoidance portion 523 can be opened on the side wall 521 to make the upper and lower sides of the top wall 522 suspended, so that the first pressing portion 2122 and the second pressing portion 2123 can be respectively extended into, so that a part of the top wall 522 is formed as the supporting portion 51, and extends between the first pressing portion 2122 and the second pressing portion 2123, that is, the supporting portion 51 extends into the second bayonet portion 2121.

[0066] Combination Figure 1 and Figure 4 As shown, in some embodiments, the function card 100 also includes at least one first liquid cooling interface 6, and the at least one first liquid cooling interface 6 is located on the bottom surface 1001; the device to be connected 200 includes at least one board connector 7 and at least one second liquid cooling interface 8, and the plug-in state of the function card 100 and the device to be connected 200, at least one gold finger 3 is plug-connected with at least one board connector 7, and at least one first liquid cooling interface 6 is plug-connected with at least one second liquid cooling interface 8.

[0067] In this embodiment, in order to improve the heat dissipation capacity of the function card 100, at least one first liquid cooling interface 6 is further provided on the bottom surface 1001 of the function card 100, and at least one second liquid cooling interface 8 is provided on the device to be connected 200. When the function card 100 is inserted into the device to be connected 200, the first liquid cooling interface 6 and the second liquid cooling interface 8 are plugged and connected, and the coolant can also enter the liquid cooling circuit of the function card 100 through the second liquid cooling interface 8 and the first liquid cooling interface 6, absorb the heat of the function card 100, and take the heat away, thereby realizing heat dissipation and cooling of the function card 100.

[0068] In some possible implementations, the board connector 7 is a slot.

[0069] In some other possible implementations, the number of the first liquid cooling interfaces 6 is two, and both are male interfaces, and the number of the second liquid cooling interfaces 8 is also two, and both are female interfaces. One first liquid cooling interface 6 and one second liquid cooling interface 8 are plug-connected to serve as an inlet channel for the cooling liquid, and another first liquid cooling interface 6 and another second liquid cooling interface 8 are plug-connected to serve as an outlet channel for the cooling liquid. In addition, the size and volume of the female interface are larger, and the size and volume of the male interface are smaller, so that the male interface is more suitable for being arranged on the function card 100.

[0070] Combination Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments, the handle assembly 2 also includes a rotating shaft member 22 and a first elastic member 23.

[0071] Through the above arrangement, the handle member 21 is rotatably connected to the connection body 1 by the rotating shaft member 22, and the first elastic member 23 provides an elastic force for the handle member 21, so that the handle member 21 is kept at the target position in the natural state (not subject to external force), and the target position is, for example, a position between the insertion state and the extraction state. When the handle member 21 is located at the target position, the lever portion 212 does not interfere with the device to be connected 200, and the function card 100 can be smoothly aligned and inserted into the device to be connected 200, or removed from the device to be connected 200. After the function card 100 is inserted into the device to be connected 200, an external force is applied to the operating portion 211, and the handle member 21 overcomes the elastic force of the first elastic member 23 and rotates along the first direction A1, and the lever portion 212 presses against the device to be connected 200, so that the function card 100 moves along the insertion direction B1.

[0073] The connection mechanism of this embodiment can use the locking assembly 24 to lock the position of the handle member 21 after the function card 100 and the device to be connected 200 are fully plugged in, so that the lever portion 212 always presses the device to be connected 200 along the insertion direction B1, thereby allowing the function card 100 to be stably and reliably plugged into the device to be connected 200.

[0074] Combination Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments, the connecting body 1 includes a platform portion 11, the handle piece 21 is rotatably connected to one end of the platform portion 11, and the operating portion 211 extends toward the other end of the platform portion 11; the locking block 241 is slidably set on the platform portion 11, and the locking block 241 is clamped and fixed to the operating portion 211.

[0075] Through the above arrangement, the locking block 241 can slide along the platform portion 11 to achieve locking and unlocking of the position of the handle member 21, and the structure is simple and reliable.

[0076] In some possible implementations, reference Figure 7 As shown, a locking bayonet 2111 is provided at a position of the handle 21 close to the operating portion 211 , and the locking block 241 cooperates with the locking bayonet 2111 to lock the position of the handle 21 .

[0077] For example, reference Figure 7 , Figure 8 and Fig. 9 As shown, the locking assembly 24 further includes a second elastic member 242 , which is used to provide an elastic force for the locking block 241 , so that the locking block 241 is clamped with the locking bayonet 2111 in a natural state, thereby locking the position of the handle 21 .
