[0045] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0046] Reference below Figure 1-Figure 11 The expansion card module 100 according to an embodiment of the present invention is described. The present invention also proposes a server 1000 having the expansion card module 100 .

[0047] Combination Figure 1-Figure 11 As shown, the expansion card module 100 of the server 1000 of the embodiment of the present invention includes: a first housing 20, a plurality of expansion cards, wherein the server 1000 includes: a circuit board 30, a plurality of expansion cards are stacked and arranged in the first housing 20, the circuit board 30 is arranged at the bottom of the first housing 20, and the circuit board 30 and the plurality of expansion cards are selectively plugged and matched. The first housing 20 and the circuit board 30 define a space for accommodating the plurality of expansion cards, that is, the circuit board 30 and the first housing 20 can protect the plurality of expansion cards.

[0048] Furthermore, the expansion card module 100 further includes: a locking assembly 10, the locking assembly 10 includes: a first locking member 11 and a second locking member 12, the first locking member 11 is arranged on the upper end surface of the first housing 20, and the second locking member 12 is arranged on one side of the first housing 20. Furthermore, the first locking member 11 has a locking position and an unlocking position, when the first locking member 11 is located at the locking position, the first locking member 11 and the second locking member 12 are locked and matched, and the first locking member 11 is also engaged with the circuit board 30, and the first locking member 11 is also positioned and matched with the circuit board 30, and multiple expansion cards and the circuit board 30 are plugged and matched. In this way, by setting the first locking member 11 and the second locking member 12, when the first locking member 11 and the second locking member 12 are locked and matched, the first locking member 11 can be snap-fitted with the circuit board 30, and the first locking member 11 can also be positioned and matched with the circuit board 30. Since the first locking member 11 is fixed to the first shell 20, the snap-fit ​​connection between the first shell 20 and the circuit board 30 can be achieved, thereby achieving the fixation of the expansion card module 100.

[0049] And, when the first locking member 11 is in the unlocked position, the first locking member 11 and the second locking member 12 are separated, and the first locking member 11 is separated from the circuit board 30. That is, when the expansion card module 100 is disassembled, the locking cooperation between the first locking member 11 and the second locking member 12 is cancelled, so that the first locking member 11 is separated from the circuit board 30, that is, the first locking member 11 is not engaged with the circuit board 30, nor is it positioned and matched with the circuit board 30, so that the expansion card module 100 can be disassembled from the server 1000.

[0050] Furthermore, the first locking member 11 can also be used as a handle for taking out the expansion card module 100 , which makes it easier to take out the expansion card module 100 .

[0051] Thus, the expansion card module 100 and the circuit board 30 are fixedly connected by the locking of the first locking member 11 and the second locking member 12, and the first locking member 11 can be used as a handle for taking out the expansion card module 100.

[0052] Among them, Figure 8 and Fig. 9As shown, a locking groove 111 is provided on the first locking member 11, and a locking tongue 121 is provided on the side of the second locking member 12 facing the first locking member 11, and the locking tongue 121 selectively locks and cooperates with the locking groove 111. In this way, the first locking member 11 and the second locking member 12 are locked and cooperated through the cooperation of the locking tongue 121 and the locking groove 111. That is, when the first locking member 11 is in the locking position, the locking tongue 121 and the locking groove 111 are locked and cooperated, so that the first locking member 11 and the second locking member 12 can be locked together, and then the first housing 20 can be fixed on the circuit board 30. Specifically, the lower surface of the locking tongue 121 abuts against the lower surface of the locking groove 111.

[0053] And, if Figure 8 As shown, a first receiving groove 112 is provided below the locking groove 111, and when the first locking member 11 is in the unlocked position, the locking tongue 121 is located in the first receiving groove 112. Thus, the first receiving groove 112 is provided below the locking groove 111, so that when the first locking member 11 is in the unlocked position, the locking tongue 121 can be located in the first receiving groove 112, so that the space of the first locking member 11 can be reasonably utilized, and the size of the first locking member 11 in the width direction can be reduced.

[0054] And, refer to Figure 8 and Fig. 9 As shown, a first guiding slope 113 is provided on a side of the first receiving groove 112 away from the locking groove 111, and a second guiding slope 122 is provided on a side of the locking tongue 121 facing the first locking member 11. In this way, the first guiding slope 113 on the first receiving groove 112 and the second guiding slope 122 on the locking tongue 121 guide and cooperate with each other, that is, when the first locking member 11 moves from the unlocking position to the locking position, the second locking member 12 and the first receiving groove 112 cooperate with each other, which can facilitate the movement of the first locking member 11 and the second locking member 12.

[0055] like Figure 4As shown, the locking assembly 10 further includes: a first sliding member 114, a first slide groove 115 is provided on the first locking member 11, and the first sliding member 114 includes: a first sliding portion and a first fixed portion, one end of the first sliding portion is fixed to the first housing 20, and the other end of the first sliding portion is connected to the first fixed portion after passing through the first slide groove 115, and the first sliding portion slides in the first slide groove 115. That is, when the first locking member 11 moves between the locking position and the unlocking position, the first locking member 11 slides in the up and down direction through the cooperation between the first sliding member 114 and the first locking member 11. Specifically, the first sliding member 114 is divided into a first sliding portion and a first fixed portion, wherein the first sliding portion slides in the first slide groove 115, and the first fixed portion is fixed to one end of the first sliding portion, that is, the first fixed portion abuts against one end of the first locking member 11 away from the first housing 20, so that the degree of freedom of the first locking member 11 can be limited.

[0056] The first sliding part may be a sliding column, that is, a columnar sliding column sliding in the first sliding groove 115 , and the first fixing part may be a fixing gasket, which is connected to the sliding column, and the outer diameter of the fixing gasket is larger than the inner diameter of the first sliding groove 115 .

[0057] Furthermore, the first sliding portion may be integrally formed on the first shell 20 , and of course the first sliding portion may also be fixed to the first shell 20 by rivets.

[0058] Further, refer to Figure 4 As shown, there may be at least two first sliding members 114, and at least two first sliding members 114 are arranged at intervals in the up-down direction. In this way, at least two first sliding members 114 are arranged in the up-down direction, so that the first locking member 11 and the first housing 20 are matched through at least two first sliding members 114, which can improve the connection stability between the first locking member 11 and the first housing 20 on the one hand, and make the first locking member 11 more stable when sliding up and down on the other hand.

[0059] There may be at least two first slide grooves 115, that is, at least two first sliding members 114 correspond to at least two first slide grooves 115 one by one, and any first sliding member 114 slides in any first slide groove 115. Alternatively, there may be one first slide groove 115, and at least two first sliding members 114 fit in one first slide groove 115.

[0060] And, if Figure 4As shown, the locking assembly 10 further includes: a first reset member 14, one end of which is connected to the first housing 20, and the other end of which is connected to the first locking member 11. In this way, the first reset member 14 can provide a reset force to the first locking member 11, that is, when the first locking member 11 is in the locked position, the first reset continues to provide a reset force to the first locking member 11, but due to the locking cooperation between the first locking member 11 and the second locking member 12, the first locking member 11 cannot move. When the first locking member 11 and the second locking member 12 are disconnected, the reset force of the first reset member 14 is released, and the first locking member 11 slides from the locked position to the unlocked position under the reset force of the first reset member 14.

[0061] The first restoring member 14 may be a spring.

[0062] Furthermore, combined with Figure 8 and Fig.10 As shown, the first housing 20 is provided with a first connecting frame 22, the first locking member 11 is provided with a first avoidance groove 116 and a second connecting frame 117, the second connecting frame 117 and the first avoidance groove 116 are arranged at intervals, the first connecting frame 22 moves in the first avoidance groove 116, one end of the first reset member 14 is connected to the first connecting frame 22, and the other end of the first reset member 14 is connected to the second connecting frame 117. In this way, the first housing 20 is provided with a first connecting frame 22, and the first locking member 11 is provided with a second connecting frame 117, and the two ends of the first reset member 14 are provided with hooks, and the hooks at the two ends are respectively connected to the first connecting frame 22 and the second connecting frame 117, so that the first reset member 14 can be connected to the first housing 20 and the first locking member 11. And, the first avoidance groove 116 is provided on the first locking member 11, so that when the first locking member 11 moves up and down, the first connecting frame 22 can slide in the first avoidance groove 116, so as to play a role of avoidance.

[0063] In addition, if Figure 4-Figure 6 As shown, the expansion card module 100 further includes: a fixing member 13, the fixing member 13 is arranged at the bottom of the first housing 20, a first clamping portion 131 is arranged on the fixing member 13, and a second clamping portion 31 is arranged on the circuit board 30, and the first clamping portion 131 and the second clamping portion 31 are selectively clamped and matched. That is to say, when the first locking member 11 and the second locking member 12 are locked and matched, the fixing member 13 and the circuit board 30 are clamped through the first clamping portion 131 and the second clamping portion 31, so that when the first locking member 11 and the second locking member 12 are locked and matched, the first housing 20 and the circuit board 30 are clamped, and when the first locking member 11 and the second locking member 12 are separated, the first housing 20 and the circuit board 30 are separated.

[0064] Specifically, the first clamping portion 131 is one of a clamping buckle and a clamping slot, and the second clamping portion 31 is the other of the clamping buckle and the clamping slot. In this way, the first housing 20 and the circuit board 30 can be clamped together through the clamping cooperation between the clamping buckle and the clamping slot, and the clamping method of the clamping buckle and the clamping slot is relatively simple, that is, it is convenient not only to clamp the clamping buckle and the clamping slot, but also to separate the clamping buckle and the clamping slot.

[0065] And, if Figure 6 As shown, a clamping hole 132 is provided in the first clamping portion 131, and a clamping column 118 is provided on the side of the first locking member 11 facing the fixing member 13, and the clamping column 118 selectively locks with the clamping hole 132. In this way, a buckle is provided on the first clamping portion 131, and a clamping column 118 is provided on the side of the first locking member 11 facing the fixing member 13, so that when the first locking member 11 and the second locking member 12 are locked and matched, the clamping column 118 on the first locking member 11 can also lock and match with the clamping hole 132, so that the connection strength between the first housing 20 and the circuit board 30 can be further improved.

[0066] The first clamping portion 131 is a circular elastic clamping portion, which is divided into a plurality of sub-clamps, and a gap is provided between two adjacent sub-clamps, so that the deformation of the sub-clamps is convenient, and the clamping column 118 is an elastic clamping column 118. Thus, when the clamping column 118 and the first clamping portion 131 are clamped, there is a clearance fit between the clamping column 118 and the first clamping portion 131, so that the connection strength between the first housing 20 and the circuit board 30 can be further improved.

[0067] Reference Figure 4 and Figure 6 As shown, the circuit board 30 is provided with a first positioning portion 32, the first positioning portion 32 and the locking hole 132 are arranged at intervals, the first locking member 11 is provided with a second positioning portion 119, the second positioning portion 119 and the locking column 118 are arranged at intervals, and the first positioning portion 32 and the second positioning portion 119 are positioned and matched. That is to say, when the first locking member 11 is located at the locking position, the second positioning portion 119 on the first locking member 11 and the first positioning column on the circuit board 30 are positioned and matched, so that the positioning and matching between the first locking member 11 and the circuit board 30 can be achieved, thereby facilitating the locking between the first locking member 11 and the circuit board 30, and improving the connection stability between the first locking member 11 and the first circuit board 30, and because the first locking member 11 is arranged on the first shell 20, the connection strength between the first shell 20 and the circuit board 30 can also be improved.

[0068] Further, the first positioning portion 32 is one of a positioning post and a positioning hole, and the second positioning portion 119 is the other of the positioning post and the positioning hole, and the positioning post and the positioning hole are positioned and matched. In this way, through the cooperation of the positioning post and the positioning hole, the cooperation between the first housing 20 and the circuit board 30 can be facilitated. Specifically, when the expansion card module 100 and the circuit board 30 are plugged and matched, the cooperation of the positioning post and the positioning hole can prevent the first housing 20 from being offset, thereby improving the connection stability between the expansion card module 100 and the circuit board 30.

[0069] In addition, if Fig.10 As shown, the first housing 20 is provided with a second receiving groove 21, and the first locking member 11 is arranged in the second receiving groove 21. Thus, by providing the second receiving groove 21 on the first housing 20, the first locking member 11 can be arranged in the second receiving groove 21, which can facilitate the installation of the first locking member 11 on the one hand, and can reasonably utilize the space of the first housing 20 on the other hand.

[0070] And, if Figure 7 As shown, the locking assembly 10 further includes: a second reset member 15, one end of which is connected to the first housing 20 and the other end of which is connected to the second locking member 12. In this way, the second reset member 15 can provide a reset force to the second locking member 12, that is, when the first locking member 11 is in the locked position, the first reset member continuously provides a reset force to the second locking member 12, so that the second locking member 12 and the first locking member 11 are continuously locked and matched, and when the expansion card module 100 needs to be disassembled, the second locking member 12 is pushed to move toward the side away from the first locking member 11, so that the second locking member 12 and the first locking member 11 are separated.

[0071] Reference Figure 7 and Fig. 9 As shown, the locking assembly 10 further includes: a second sliding member 123, a second slide groove 23 is provided on the first housing 20, and the second sliding member 123 includes: a second sliding portion and a second fixed portion, one end of the second sliding portion is fixed to the second locking member 12 and the other end is connected to the second fixed portion after passing through the second slide groove 23, and the second sliding portion slides in the second slide groove 23. That is, when the second locking member 12 slides on the first housing 20, the second locking member 12 slides in the front-to-back direction through the cooperation between the second sliding member 123 and the second locking member 12. Specifically, the second sliding member 123 is divided into a second sliding portion and a second fixed portion, wherein the second sliding portion slides in the second slide groove 23, and the second fixed portion is fixed to one end of the second sliding portion, that is, the second fixed portion abuts against one end of the second locking member 12 away from the first housing 20, so that the degree of freedom of the second locking member 12 can be limited.

[0072] The second sliding part may be a sliding column, that is, a columnar sliding column sliding in the second sliding groove 23 , and the second fixed part may be a fixed gasket, which is connected to the sliding column, and the outer diameter of the fixed gasket is larger than the inner diameter of the second sliding groove 23 .

[0073] Furthermore, the second sliding portion may be integrally formed on the first locking member 11 , and of course the second sliding portion may also be fixed to the first locking member 11 by rivets.

[0074] Further, refer to Figure 7 and Fig. 9 As shown, there may be at least two second sliding members 123, and at least two second sliding members 123 are arranged at intervals in the front-to-back direction. In this way, at least two second sliding members 123 are arranged in the front-to-back direction, so that the second locking member 12 and the first housing 20 are matched through at least two second sliding members 123, which can improve the connection stability between the second locking member 12 and the first housing 20 on the one hand, and make the second locking member 12 more stable when sliding in the front-to-back direction on the other hand.

[0075] There may be at least two second slide grooves 23, that is, at least two second sliding members 123 correspond to at least two second slide grooves 23 one by one, and any second sliding member 123 slides in any second slide groove 23. Alternatively, there may be one second slide groove 23, and at least two second sliding members 123 may fit in one second slide groove 23.
