Description

Expansion card holder

The invention relates to an expansion card fixing frame, in particular to an expansion card fixing frame with a deflector.

In order to make electronic devices (such as desktop computers, notebook computers, or servers) meet the requirements for use, users usually plug expansion cards (such as graphics cards, network cards, sound cards, or memory cards) into Riser card, and then plug the riser card into the motherboard to improve the performance of the electronic device.

Generally speaking, riser cards and expansion cards are mostly fixed on a fixing frame, and the fixing frame is equipped with an air deflector to guide the heat dissipation airflow in the electronic device, so that the airflow can be concentrated to the expansion card to maintain the airflow for expansion. The effect of card heat dissipation. However, the fixing frame is designed to support expansion cards of different thicknesses, but currently the air deflector is a fixed plate, and a single size air deflector only corresponds to an expansion card of a specific thickness. Therefore, when a user adopts a thicker or thinner expansion card, it is often necessary to remove the original air deflector and then install the air deflector corresponding to the size of the expansion card, which is quite inconvenient in use.

The present invention is to provide an expansion card fixing frame to solve the problem of inconvenient replacement of the wind deflector described in the prior art.

An expansion card holder disclosed in an embodiment of the present invention is used for accommodating a riser card and an expansion card inserted in the riser card. The expansion card holder includes a shell and a deflector. The shell includes a back, a first side, a second side, and a third side.

The first side and the second side are located on opposite sides of the back, and the third side is located on the first and second sides. The first side and the second side are connected between the side parts. The back, the first side, the second side, and the third side jointly form an accommodating space, and the accommodating space is used for accommodating the riser card and the expansion card. The first side part includes an air inlet communicating with the accommodating space. The deflector is located in the accommodating space and is pivoted on the shell. The baffle is used for pivoting relative to the housing, and the area of the orthographic projection of the baffle on the first side portion overlapping the air inlet is adjusted.

According to the expansion card holder disclosed in the above embodiment, since the deflector is pivoted on the housing, and the deflector can pivot relative to the housing, the orthographic projection of the adjusting deflector on the first side overlaps the air inlet Therefore, the pivot angle of the deflector can be adjusted according to the thickness of the expansion card used, so that the airflow from the air inlet into the accommodating space flows to the expansion card in a concentrated manner to prevent the airflow from flowing to the invalid area. Therefore, a single baffle is suitable for expansion cards of different thicknesses, so the steps of removing the baffle and replacing it with another suitable baffle can be omitted, so the convenience of use is improved.

The guiding groove 111 has an arc shape and includes a first end 1111 and a second end 1112 opposite to each other. The first end 1111 of the guiding groove 111 is closer to the first side portion 12 than the second end 1112, and the second end 1112 is closer to the third side portion 14 than the first end 1111. The two positioning holes 112 and 113 are arranged along an arc S whose center is the pivot axis P of the plate portion 21 of the deflector 20. The two positioning holes 112 and 113 are closer to the pivot axis P of the plate portion 21 of the deflector 20 than the guiding groove 111. The positioning hole 112 is closer to the first end 1111 of the guiding groove 111 than the positioning hole 113, and the positioning hole 113 is closer to the second end 1112 of the guiding groove 111 than the positioning hole 112.

In this embodiment, the two positioning holes 112 and 113 are not limited to being closer to the pivot axis P of the plate portion 21 of the deflector 20 than the guiding groove 111 is. In other embodiments, the two positioning holes may be farther away from the pivot axis P of the plate portion 21 of the baffle 20 than the guiding groove 111.

The plate portion 21 of the deflector 20 includes an air guide surface 211 facing the first side portion 12, and the deflector 20 also includes an elastic arm portion 22, a guide block portion 23, a positioning block portion 24, and an operation部25. The elastic arm portion 22 includes a first extension plate 221 and a second extension plate 222.

The normal direction of the air guide surface 211 extends. The guiding block portion 23 is connected to a side of the first extension board 221 adjacent to the back 11, and the positioning block portion 24 is connected to a side of the second extension board 222 adjacent to the back 11. The distance between the positioning block portion 24 and the pivot axis P of the plate portion 21 is different from the distance between the guide block portion 23 and the pivot axis P of the plate portion 21. In detail, the positioning block portion 24 is closer to the pivot axis P of the plate portion 21 than the guide block portion 23 is. The guiding block 23 is movably located at the second end 1112 of the guiding groove 111, and the positioning block 24 is movably located on the arc S and separately located at the positioning hole 113. The operating portion 25 is located on the side of the back 11 facing away from the accommodating space 30, and the operating portion 25 is movably connected to the end of the guiding block 23 away from the first extension plate 221, so that the positioning block 24 is located or separated from the positioning hole 113 . In this embodiment, the width W1 of the operating portion 25 is greater than the width W2 of the guiding block portion 23 and the width W3 of the guiding groove 111, but it is not limited thereto. In other embodiments, the width of the operating portion 25 of the deflector 20 may be less than or equal to the width of the guiding block portion 23 and the width of the guiding groove 111.

In this embodiment, the plate portion 21, the elastic arm portion 22, the guide block portion 23, the positioning block portion 24, and the operating portion 25 of the deflector 20 are, for example, integrally formed parts, and the back 11 of the housing 10 also includes a Sliding groove 114 and a relief hole 115. The opposite ends of the sliding groove 114 are respectively connected to the second end 1112 of the guiding groove 111 and the relief hole 115, and the sliding groove 114 and the relief hole 115 are farther away from the pivot axis of the plate portion 21 of the deflector 20 than the guiding groove 111 Line P. The aperture R of the relief hole 115 is larger than the width W4 of the sliding groove 114 and the width W3 of the guiding groove 111. The width W1 of the operating portion 25 is smaller than the aperture R of the relief hole 115 and larger than the width W4 of the sliding groove 114, and the width W2 of the guiding block portion 23 is smaller than the width W4 of the sliding groove 114.

Next, the process of assembling the deflector 20 to the housing 10 will be described below. Firstly, the operating portion 25 of the baffle 20 is inserted through the vacant hole 115 so that the plate portion 21 is located in the accommodating space 30 and the operating portion 25 is located on the side of the back 11 facing the accommodating space 30. Next, move the deflector 20 so that the guide block 23 of the deflector 20 is guided by the sliding groove 114 to be located at the second end 1112 of the guide groove 111, and then the plate 21 of the deflector 20 is opposite to each other. The two sides are pivoted on the pivoting convex portion 16 and the back 11, which completes the assembly of the baffle 20 to the housing 10.

In this embodiment, the sliding groove 114 and the relief hole 115 of the back 11 of the housing 10 are provided to allow the deflector 20 to be assembled to the housing 10, but the back 11 of the housing 10 is not limited to include sliding grooves. 114 and the clearance hole 115. In other embodiments, the back of the housing may be free of sliding grooves and relief holes. In such a configuration, the operating portion of the deflector must be separately assembled to the guide block, for example, so that the deflector can also be assembled to the housing.

In addition, the sliding groove 114 is not limited to be connected to the second end 1112 of the guiding groove 111. In other embodiments, the sliding groove may be connected to the first end of the guiding groove or anywhere between the first end and the second end of the guiding groove.

As shown in Figures 3 and 4, when the riser card 2a is installed in the accommodating space 30, and the two expansion cards 3a are inserted into the riser card 2a, the air inlets 122, 123, 124, and 125 respectively face the two Expansion card 3a, and the air inlet 121 faces the air guiding surface 211 of the plate portion 21 of the air deflector 20. When the cooling fan blows the airflow F from the air inlets 122, 123, 124, 125 into the accommodating space 30, the airflow F passing through the air inlets 122, 123, 124, 125 will directly flow through the two expansion cards 3a. Moreover, the airflow F passing through the air inlet 121 is guided by the air guide surface 211 to flow toward the expansion card 3a, so that the airflow F passing through the air inlets 122, 123, 124, 125 concentrates on the two expansion cards 3a to dissipate heat. It can be seen that the baffle 20 can prevent the airflow F from directly flowing to the second side portion 13 and being lost, so the heat dissipation effect of the airflow F on the expansion card 3a can be maintained.

Next, please refer to Figure 5 and Figure 6. 5 is a schematic partial cross-sectional view of the expansion card holder of FIG. 1 accommodating riser cards and expansion cards of different sizes. Fig. 6 is a schematic side view of Fig. 5.

As shown in Figures 5 and 6, when the user changes from the second expansion card 3a with the larger thickness T1 to the other expansion card 3b with the smaller thickness T2, the user will usually change the width W6 to be smaller than the width of the riser card 2a. Another riser card 2b of W5, to match with expansion card 3b. When the riser card 2b is installed in the accommodating space 30 and the two expansion cards 3b are inserted into the riser card 2b, the air inlets 124 and 125 respectively face the two expansion cards 3b, and the air inlet 121 faces The air guiding surface 211 of the plate portion 21 of the baffle 20, but the air inlets 122 and 123 are directly facing the second side portion 13. In this case, part of the airflow F will flow directly to the second side portion 13 from between the expansion card 3b and the baffle 20 and be lost.

Next, please refer to Figure 7 and Figure 9. 7 is a partial cross-sectional view of the guide block of the guide plate of FIG. 5 at the second end of the guide groove. Fig. 8 is a partial bottom view of the positioning block of the baffle of Fig. 5 in another positioning hole. Fig. 9 is a schematic side view of Fig. 7.

As shown in FIGS. 7 and 8, in order to avoid the aforementioned situation, the user can press the operating portion 25 of the baffle 20 to make the elastic arm portion 22 elastically deform relative to the plate portion 21, and the positioning block portion 24 is separated from the positioning hole 113. Then, the operating portion 25 is pushed to make the plate portion 21 of the deflector 20 pivot toward the first side portion 12, and the guiding block portion 23 is moved from the second end 1112 of the guiding groove 111 to the first end 1111. Then, the application of force to the operating portion 25 is stopped to allow the elastic arm portion 22 to rebound and the positioning block portion 24 to be locked into the positioning hole 112.

As shown in Figure 9, during the pivoting of the plate portion 21 of the deflector 20 toward the first side portion 12, the orthographic projection of the plate portion 21 of the deflector 20 on the first side portion 12 overlaps the area of the air inlet Will gradually increase. In other words, as shown in FIG. 6, before the deflector 20 is pivoted, originally only the air inlet 121 faces the plate portion 21 of the deflector 20, but as shown in FIG. 9, the deflector 20 faces the first After the side portion 12 is pivoted, the other two air inlets 122 and 123 also face the plate portion 21 of the baffle 20. In this way, when the air inlets 121, 122, 123 face the plate 21 of the baffle 20 and the air inlets 124, 125 face the two expansion cards 3b, respectively, the effect of concentrated air flow F is also achieved, so it can be avoided The air flow F flows to the ineffective area.

Conversely, when the expansion card 3a with a thicker thickness is to be used instead, the air deflector 20 can be pivoted toward the third side 14 so that the orthographic projection of the plate 21 of the air deflector 20 and the first side 12 overlap The area at the air inlet will gradually decrease. In this way, in addition to maintaining the effect that the airflow F is concentrated on the expansion card 3a, interference between the expansion card 3a and the air deflector 20 with a thicker thickness can also be avoided.

In this embodiment, since the deflector 20 is pivoted to the housing 10, and the deflector 20 can pivot relative to the housing 10, the orthographic projection of the adjusting deflector 20 on the first side 12 overlaps the air inlet Therefore, the pivot angle of the deflector 20 can be adjusted according to the size of the expansion card, so that the airflow F flowing into the accommodating space 30 from the air inlets 121, 122, 123, 124, 125 flows to the expansion card in a concentrated manner to avoid The air flows to the ineffective area. Therefore, a single baffle 20 is suitable for expansion cards of different thicknesses, so the steps of removing the baffle 20 and replacing it with another suitable baffle can be omitted, so the convenience of use is improved.

In this embodiment, the number of the air inlets 121, 122, 123, 124, 125 of the first side portion 12 is not limited to five. In other embodiments, the number of the air inlets of the air inlets of the first side portion may be greater than five or less than five.

In addition, by the combination of the two positioning holes 112, 113 and the positioning block portion 24 of the deflector 20, the pivot angle of the deflector 20 can be positioned to prevent the deflector 20 from pivoting unexpectedly due to external forces, thereby reducing The probability of loss of airflow F is determined.

In this embodiment, the number of positioning holes 112 and 113 is not limited to two. In other embodiments, the number of positioning holes can be adjusted to more than two or less than two according to requirements. Wherein, when there is no positioning hole on the back of the casing, the baffle plate does not need the second extension plate, the positioning block part, the first extension plate and the operation part, and the guide block part can be directly connected to the plate part.

In addition, by the arrangement of the sliding groove 114 and the relief hole 115 farther away from the pivot axis P of the plate 21 than the guide groove 111, it can be ensured that during the pivoting process of the deflector 20, the operating portion 25 will not move to allow The hole 115 is located so as to reduce the probability of the baffle 20 detaching from the back 11 of the housing 10.

Furthermore, by setting the width W1 of the operating portion 25 of the baffle 20 to be greater than the width W3 of the guide groove 111, the pressing stroke of the operating portion 25 can be restricted. Therefore, even if the operating portion 25 is pressed excessively, the operating portion 25 remains It is located on the side of the back 11 of the housing 10 away from the accommodating space 30, which reduces the probability of the baffle 20 detaching from the back 11.

In the above description, the description of the two expansion cards inserted on the riser card is only an example, and is not intended to limit the present invention. In other embodiments, the number of expansion cards inserted on the riser card can be one or more than two, and the pivot angle of the air deflector can be adjusted according to the number of expansion cards and the insertion position.

According to the expansion card holder disclosed in the above embodiment, since the deflector is pivoted on the housing, and the deflector can pivot relative to the housing, the orthographic projection of the adjusting deflector on the first side overlaps the air inlet Therefore, the pivot angle of the deflector can be adjusted according to the size of the expansion card, so that the airflow from the air inlet into the accommodating space flows to the expansion card in a concentrated manner to prevent the airflow from flowing to the invalid area. Therefore, a single baffle is suitable for expansion cards of different thicknesses, so the steps of removing the baffle and replacing it with another suitable baffle can be omitted, so the convenience of use is improved.

With the combination of the two positioning holes and the positioning block of the deflector, the pivoting angle of the deflector can be positioned to prevent the deflector from pivoting unexpectedly due to external forces, thereby reducing the probability of air flow loss.

In addition, through the arrangement of the sliding groove and the relief hole farther from the pivot axis of the plate than the guide groove, it can be ensured that the operating part will not move to the relief hole during the pivoting process of the deflector, so the guide can be lowered. The probability that the flow plate will disengage from the back of the shell.

Although the present invention is disclosed in the foregoing preferred embodiments as above, it is not intended to limit the present invention. Anyone familiar with similar art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of patent protection for inventions shall be determined by the scope of patent applications attached to this specification.
