Description

Technical Field

[0001] The present invention relates to the technical field of computer accessories, and in particular to a PCIe card compression structure and a computer. Background Art

[0002] At present, servers require more and more PCIe (peripheral component interconnect express, a high-speed serial computer expansion bus standard) cards. Riser adapter cards are adapter cards used to transfer PCIe cards to servers, or called expansion cards. Riser adapter cards can enable servers to support more PCIe cards. PCIe cards are usually installed on PCIe card mounting brackets and fixed to the PCIe card mounting brackets through corresponding card pressing structures, so that they can be installed in the server housing through the PCIe card mounting brackets.

[0003] Currently, the PCIe cards required by the server have a variety of different heights. However, the existing PCIe card pressing structure is only applicable to the installation of PCIe cards of a single height. For PCIe cards of different heights, different card pressing structures need to be configured, which makes it inconvenient to install the PCIe card. Summary of the invention

[0004] Based on this, it is necessary to provide a PCIe card pressing structure and a computer that can be applicable to PCIe cards of different heights in order to solve the technical problem that the traditional PCIe card pressing structure is only applicable to PCIe cards of a single height.

[0005] The embodiment of the present application provides a PCIe card pressing structure, including: a base and a torsion spring, wherein the torsion spring includes:

[0006] A spring coil having a first end and a second end disposed opposite to each other in an axial direction, wherein the spring coil is used to press the PCIe card in a direction away from the base;

[0007] A first torsion arm connected to the first end, wherein an extending direction of the first torsion arm is perpendicular to an axial direction of the spring coil; and

[0008] a second torsion arm connected to the second end, wherein the extension direction of the second torsion arm is perpendicular to the axial direction of the spring coil; wherein one end of the first torsion arm away from the spring coil and one end of the second torsion arm away from the spring coil are respectively slidably matched with the base, and can move toward or away from each other along a first direction to change the distance of the spring coil relative to the base, so that the spring coil applies a force to press the PCIe card in a direction away from the base.

[0009] When the above-mentioned PCIe card pressing structure is used to install the PCIe card on the motherboard of the computer, the PCIe card is located between the motherboard and the PCIe card pressing structure, and the torsion spring is located between the base and the PCIe card. The relative positions of the base and the motherboard are fixed. One end of the PCIe card is installed on the motherboard, and the other end is pressed by the spring coil. When PCIe cards of different heights are installed, since the relative position of the base relative to the motherboard is fixed, the spacing between PCIe cards of different heights and the base is different. When installing PCIe cards of different heights, the spring coil can be abutted against the PCIe card, and the first torsion arm and the second torsion arm can be squeezed to different degrees by the base, so that different sizes of spacing can be formed between the base and the spring coil, thereby being able to adapt to the different spacings between PCIe cards of different heights and the base. It can be seen that the above-mentioned PCIe card pressing structure can be adapted to reliably install PCIe cards of various heights on the motherboard.

[0010] In one embodiment, the PCIe card pressing structure further includes: a support shaft, the support shaft includes: a connecting section and a supporting section arranged along the axial direction and fixedly connected, the connecting section is passed through the spring coil, and the supporting section is used to abut against the PCIe card.

[0011] During the installation of the PCIe card, when the spring coil abuts against the PCIe card, it can indirectly abut against the PCIe card through the support section, thereby indirectly providing pressure to the PCIe card through the support section, and thus there is no need for the spring coil to directly abut against the PCIe card. Since the spring coil is not directly abutted against the PCIe card, and since the spring coil is sleeved on the connecting section, when the spring coil undergoes elastic torsional deformation, it can rotate relative to the connecting section, thereby facilitating the torsional deformation of the spring coil. It can be seen from this that by providing the supporting section and the connecting section, on the one hand, pressure can be indirectly provided to the PCIe card through the supporting section, and on the other hand, elastic torsional deformation of the spring coil can be facilitated through the connecting section.

[0012] In one embodiment, the PCIe card pressing structure further includes: an anti-slip sleeve, which is sleeved on the support section. Since the anti-slip sleeve is sleeved on the support section, when the spring coil abuts against the PCIe card, the anti-slip sleeve can indirectly abut against the PCIe card, thereby pressing the PCIe card. Since the outer peripheral surface of the anti-slip sleeve is a rough surface, the friction between the anti-slip sleeve and the PCIe card can be increased, which is conducive to the anti-slip sleeve reliably pressing the PCIe card.

[0013] In one embodiment, the PCIe card pressing structure further includes: a first sliding portion connected to an end of the first torsion arm away from the spring coil and slidingly engaged with the base along a first direction; and

[0014] The second sliding portion is connected to an end of the second torsion arm away from the spring coil and is slidably matched with the base along a first direction.

[0015] Through the sliding cooperation between the first sliding part and the first sliding groove and the sliding cooperation between the second sliding part and the second sliding groove, it is possible to conveniently realize the movement of the end of the first torsion arm away from the spring coil and the end of the second torsion arm away from the spring coil toward or away from each other along the first direction. Further, in this embodiment, when the first torsion arm abuts against the base, it abuts against the base indirectly through the first sliding part, so that the first sliding part can increase the contact area when the first torsion arm abuts against the base, thereby making the first torsion arm abut against the base reliably. Similarly, the second sliding part can increase the contact area when the second torsion arm abuts against the base, thereby making the second torsion arm abut against the base reliably.

[0016] In one embodiment, the number of the torsion springs is two, namely a first torsion spring and a second torsion spring, the coil of the first torsion spring and the coil of the second torsion spring are arranged axially spaced apart, the first torsion arm of the first torsion spring is arranged in parallel with the first torsion arm of the second torsion spring, and the second torsion arm of the first torsion spring is arranged in parallel with the second torsion arm of the second torsion spring;

[0017] One end of the first sliding portion is connected to the first torsion arm of the first torsion spring, and the other end is connected to the first torsion arm of the second torsion spring;

[0018] One end of the second sliding portion is connected to the second torsion arm of the first torsion spring, and the other end of the second sliding portion is connected to the second torsion arm of the second torsion spring.

[0019] The overall elastic torsion structure formed by connecting the first torsion spring, the second torsion spring, the first sliding part and the second sliding part not only increases the size of the PCIe card pressing structure along the axial direction of the spring coil, but also enables the first torsion spring and the second torsion spring to move synchronously, thereby facilitating the movement directions of the first torsion arm and the second torsion arm to be stable during the installation of the PCIe card, and the reliability of the PCIe card pressing structure is strong.

[0020] In one embodiment, the PCIe card compression structure further includes:

[0021] A first sleeve, sleeved on the first sliding part, wherein the first sliding part can slide along the base by rolling of the first sleeve; and

[0022] The second sleeve is sleeved on the second sliding part, and the second sliding part can slide along the base through the rolling of the second sleeve.

[0023] Since the first sleeve is sleeved on the first sliding part, the first sliding part can slide along the first direction by rolling the first sleeve along the base in the first direction, thereby replacing the sliding friction between the first sliding part and the base with the rolling friction between the first sleeve and the base, thereby reducing the friction resistance when the first sliding part slides relative to the base. Similarly, since the second sleeve is sleeved on the second sliding part, the second sliding part can slide along the first direction by rolling the second sleeve along the base in the first direction, thereby replacing the sliding friction between the second sliding part and the base with the rolling friction between the second sleeve and the base, thereby reducing the friction resistance when the second sliding part slides relative to the base.

[0024] In one embodiment, the PCIe card compression structure further includes: a limiting portion connected to the base and located on a side of the base close to the torsion spring; a slide groove is formed between the limiting portion and the base, and the first sliding portion and the second sliding portion are respectively located in the slide groove.

[0025] Since the first limiting portion is located on the side of the base close to the torsion spring, and a first sliding groove is formed between the first limiting portion and the base, when the first sliding portion is in the first sliding groove, it is located between the first limiting portion and the base, so that the first sliding portion is limited by the first limiting portion and the base in the second direction, thereby ensuring that the first sliding portion is reliably connected to the base. Similarly, the second sliding portion is limited by the second limiting portion and the base in the second direction, thereby ensuring that the second sliding portion is reliably connected to the base.

[0026] Another embodiment of the present application further provides a computer, including:

[0027] Motherboard;

[0028] In the PCIe card compression structure as described in any one of the above items, the relative positions of the base and the mainboard are fixed;

[0029] The PCIe card is located between the mainboard and the PCIe card pressing structure. One end of the PCIe card is installed on the mainboard, and the other end is pressed by the spring coil.

[0030] When the above-mentioned PCIe card pressing structure is used to install the PCIe card on the motherboard of the computer, the PCIe card is located between the motherboard and the PCIe card pressing structure, and the torsion spring is located between the base and the PCIe card. The relative positions of the base and the motherboard are fixed. One end of the PCIe card is installed on the motherboard, and the other end is pressed by the spring coil. When PCIe cards of different heights are installed, since the relative position of the base relative to the motherboard is fixed, the spacing between PCIe cards of different heights and the base is different. When installing PCIe cards of different heights, the spring coil can be abutted against the PCIe card, and the first torsion arm and the second torsion arm can be squeezed to different degrees by the base, so that different sizes of spacing can be formed between the base and the spring coil, thereby being able to adapt to the different spacings between PCIe cards of different heights and the base. It can be seen that the above-mentioned PCIe card pressing structure can be adapted to reliably install PCIe cards of various heights on the motherboard.

[0031] In one embodiment, the computer further comprises:

[0032] A housing for accommodating the mainboard, the PCIe card and the PCIe card pressing structure; and

[0033] The mounting part is mounted on the housing, and the base is mounted on the mounting part. The base is fixed on the housing through the mounting part, which is convenient for mounting the base.

[0034] In one embodiment, the number of the PCIe cards is at least two, the number of the PCIe card compression structures is at least two, and the PCIe cards correspond to the PCIe card compression structures one by one;

[0035] The sizes of at least two of the PCIe cards along the second direction are different from each other, wherein the second direction is the pressure direction when the spring coil presses the PCIe card.

[0036] Since the PCIe card compression structure of the present application can be applicable to the installation of PCIe cards of different heights, at least two PCIe cards can be conveniently installed on the mainboard. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Please refer to Figure 1 The embodiment of the present application provides a PCIe card compression structure 100 . The PCIe card compression structure 100 includes: a base 110 and a torsion spring 120 .

[0063] The torsion spring 120 includes: a spring coil 121, a first torsion arm 122 and a second torsion arm 123. The spring coil 121 is a spiral spring coil. The spring coil 121 has a first end and a second end that are arranged opposite to each other in the axial direction. That is, the first end and the second end are the two ends of the spring coil 121 in the axial direction. The first torsion arm 122 is connected to the first end, and the extension direction of the first torsion arm 122 is perpendicular to the axial direction of the spring coil 121. The second torsion arm 123 is connected to the second end, and the extension direction of the second torsion arm 123 is perpendicular to the axial direction of the spring coil 121. The first torsion arm 122 and the second torsion arm 123 have different extension directions, so that they are arranged at an angle. The first torsion arm 122, the second torsion arm 123 and the spring coil 121 can be integrally formed. It can be understood that if the first torsion arm 122 and the second torsion arm 123 make a relative opening movement, the angle between the first torsion arm 122 and the second torsion arm 123 increases, and the spring coil 121 undergoes elastic torsion deformation and accumulates force at the same time. At this time, if the spring coil 121, the first torsion arm 122 and the second torsion arm 123 are released, the elastic torsion force accumulated in the spring coil 121 can restore the angle between the first torsion arm 122 and the second torsion arm 123, thereby reducing the angle between the first torsion arm 122 and the second torsion arm 123.

[0064] One end of the first torsion arm 122 away from the spring coil 121 is slidably matched with the base 110 along the first direction. One end of the second torsion arm 123 away from the spring coil 121 is slidably matched with the base 110 along the first direction. When one end of the first torsion arm 122 away from the spring coil 121 and one end of the second torsion arm 123 away from the spring coil 121 move toward or away from each other along the first direction, the distance between the base 110 and the spring coil 121 can be changed, so that the cover spring coil 121 exerts pressure on the PCIe card 200.

[0065] Specifically, it can be understood that when the first torsion arm 122 and the second torsion arm 123 perform a relative opening or closing motion, the end of the first torsion arm 122 away from the spring coil 121 and the end of the second torsion arm 123 away from the spring coil 121 perform a relative moving motion towards or away from each other. The first direction is the direction in which when the first torsion arm 122 and the second torsion arm 123 perform a relative opening or closing motion, the end of the first torsion arm 122 away from the spring coil 121 and the end of the second torsion arm 123 away from the spring coil 121 perform a relative moving motion towards or away from each other.

[0066] Since one end of the first torsion arm 122 away from the spring coil 121 is slidably matched with the base 110 along the first direction, and one end of the second torsion arm 123 away from the spring coil 121 is slidably matched with the base 110 along the first direction, when the first torsion arm 122 and the second torsion arm 123 make a relative opening or closing movement, one end of the first torsion arm 122 away from the spring coil 121 slides relative to the base 110 along the first direction, and one end of the second torsion arm 123 away from the spring coil 121 slides relative to the base 110 along the first direction.

[0067] Please combine Figures 7 to 10 As shown, when the PCIe card compression structure 100 is applied to a computer 10, the PCIe card compression structure 100 can install the PCIe card 200 on the motherboard 300 of the computer 10. The computer 10 can be a notebook computer, a desktop computer, a server, etc. The computer 10 includes: a PCIe card 200, a motherboard 300, a PCIe card compression structure 100, a housing 400, and a mounting portion 500. The PCIe card 200, the motherboard 300, and the PCIe card compression structure 100 are accommodated in the housing 400.

[0068] Specifically, the mainboard 300 is installed inside the housing 400 and fixed relatively to the housing 400. The mounting portion 500 can be mounted on the housing 400 by bolt connection, snap connection, etc. The base 110 of the PCIe card compression structure 100 can be installed and fixed on the mounting portion 500, so that the base 110 and the mainboard 300 can be relatively fixed.

[0069] The PCIe card 200 is located between the motherboard 300 and the PCIe card pressing structure 100. One end of the PCIe card 200 is installed on the motherboard 300, and the other end is pressed by the spring coil 121. Specifically, the end of the PCIe card 200 with the gold finger can be directly inserted into the slot on the motherboard 300, or installed on the motherboard 300 through a riser card. The end of the PCIe card 200 facing away from its gold finger abuts against the spring coil 121, so that it can be pressed by the spring coil 121, thereby making the PCIe card 200 reliably clamped between the motherboard 300 and the spring coil 121.

[0070] Combination Figure 7 , Figure 8 as well as Fig.10 It can be understood that the PCIe card pressing structure 100 is located between the PCIe card 200 and the mounting portion 500. The base 110 is mounted on the mounting portion 500. The first torsion arm 122 of the torsion spring 120, one end away from the spring coil 121, and the second torsion arm 123, one end away from the spring coil 121, respectively abut against the base 110, so that the base 110 applies pressure toward the PCIe card 200 to the first torsion arm 122 and the second torsion arm 123, respectively, and then the spring coil 121 can apply pressure to the PCIe card 200, so that the spring coil 121 presses the end of the PCIe card 200 that is away from its gold finger.

[0071] Specifically, when installing the PCIe card 200, the end of the PCIe card 200 with the gold finger can be first installed on the mainboard 300, so that the PCIe card 200 is pre-assembled on the mainboard 300. The base 110 is installed on the installation part 500, so that the PCIe card pressing structure 100 is installed on the installation part 500. Then, the installation part 500 is installed on the housing 400.

[0072] It can be understood that during the process of installing the mounting portion 500 on the housing 400, the base 110 moves along the second direction toward the PCIe card 200 until the spring coil 121 abuts against the PCIe card 200, and the position of the spring coil 121 along the second direction is determined, wherein the second direction is the pressure direction of the spring coil 121 on the PCIe card 200. As the base 110 continues to move along the second direction toward the PCIe card 200, the base 110 will continue to press the first torsion arm 122 and the second torsion arm 123 toward the PCIe card 200. At this time, since the position of the spring coil 121 along the second direction is determined, the degree of compression of the first torsion arm 122 and the second torsion arm 123 will gradually increase, so that the end of the first torsion arm 122 away from the spring coil 121 and the end of the second torsion arm 123 away from the spring coil 121 move away from each other along the first direction. Furthermore, as the base 110 continues to move in the second direction toward the direction close to the PCIe card 200, the base 110 will move close to the spring coil 121, resulting in a decrease in the distance between the base 110 and the spring coil 121, and an increase in the degree of compression of the torsion spring 120 in the second direction, thereby increasing the pressure of the spring coil 121 on the PCIe card 200. When the base 110 moves to the right position in the second direction, the mounting portion 500 and the housing 400 can be fixed, so that the position of the base 110 in the second direction remains unchanged. At this time, the base 110 presses the end of the first torsion arm 122 away from the spring coil 121 and the end of the second torsion arm 123 away from the spring coil 121 in the direction where the PCIe card 200 is located, and the spring coil 121 presses the PCIe card 200. At this point, the installation of the PCIe card 200 is completed.

[0073] Different types of PCIe cards 200 have different heights along the second direction. When PCIe cards 200 with different heights along the second direction are installed, since the installation position of the base 110 relative to the motherboard 300 along the second direction is fixed, the final spacing between the base 110 and each PCIe card 200 is determined and different. For a PCIe card 200 with a lower height, the spacing between the PCIe card 200 and the base 110 along the second direction is larger, so that when the spring coil 121 abuts against the PCIe card 200, the base 110 squeezes the first torsion arm 122 and the second torsion arm 123 to a lesser extent along the second direction, so that a larger spacing is maintained between the base 110 and the spring coil 121, thereby being able to adapt to the larger spacing between the PCIe card 200 and the base 110. However, for a PCIe card 200 with a higher height, the distance between the PCIe card 200 and the base 110 along the second direction is smaller. Therefore, the base 110 needs to squeeze the first torsion arm 122 and the second torsion arm 123 to a greater extent along the second direction, so that a smaller distance is maintained between the base 110 and the spring coil 121, thereby being able to adapt to the smaller distance between the PCIe card 200 and the base 110.

[0074] When the PCIe card pressing structure 100 is used to install the PCIe card 200 on the motherboard 300 of the computer 10, the PCIe card 200 is located between the motherboard 300 and the PCIe card pressing structure 100, and the torsion spring 120 is located between the base 110 and the PCIe card 200. The relative positions of the base 110 and the motherboard 300 are fixed. One end of the PCIe card 200 is installed on the motherboard 300, and the other end is pressed by the spring coil 121. When the PCIe cards 200 of different heights are installed, since the relative position of the base 110 relative to the motherboard 300 is fixed, the spacing between the PCIe cards 200 of different heights and the base 110 is different. When installing PCIe cards 200 of different heights, the spring coil 121 can be abutted against the PCIe card 200, and the first torsion arm 122 and the second torsion arm 123 can be pressed to different degrees by the base 110, so that different distances can be formed between the base 110 and the spring coil 121, thereby adapting to different distances between PCIe cards 200 of different heights and the base 110. It can be seen that the above-mentioned PCIe card pressing structure 100 can adapt to reliably installing PCIe cards 200 of various heights on the mainboard 300.

[0075] Furthermore, when the PCIe card 200 is installed on the motherboard 300 of the computer 10 through the PCIe card pressing structure 100, since the first torsion arm 122 and the second torsion arm 123 are respectively abutted against the base 110, the spring coil 121 abuts against the PCIe card 200, thereby achieving abutment of the PCIe card 200 through three-point support, thereby making the PCIe card 200 reliably installed.

[0076] Please refer to Figure 1 and Figure 3 In one embodiment, the PCIe card compression structure 100 further includes: a first sliding portion 141 and a second sliding portion 142. The first sliding portion 141 is connected to an end of the first torsion arm 122 away from the spring coil 121, and slides with the base 110 along the first direction. The second sliding portion 142 is connected to an end of the second torsion arm 123 away from the spring coil 121, and slides with the base 110 along the first direction.

[0077] Specifically, in this embodiment, the first sliding portion 141 and the second sliding portion 142 are crossbars, which are arranged in parallel. The extending directions of the first sliding portion 141 and the second sliding portion 142 are perpendicular to the first direction and perpendicular to the extending directions of the first torsion arm 122 and the second torsion arm 123 .

[0078] Please refer to Figure 5 The base 110 is provided with a first slide groove 101a and a second slide groove 101b. The first sliding portion 141 slides with the first slide groove 101a along a first direction, and the second sliding portion 142 slides with the second slide groove 101b along the first direction.

[0079] Since the first sliding portion 141 is connected to the end of the first torsion arm 122 away from the spring coil 121, and the second sliding portion 142 is connected to the end of the second torsion arm 123 away from the spring coil 121, the first sliding portion 141 can be slidably matched with the first slide groove 101a and the second sliding portion 142 can be slidably matched with the second slide groove 101b, so that the end of the first torsion arm 122 away from the spring coil 121 and the end of the second torsion arm 123 away from the spring coil 121 can be easily moved toward or away from each other along the first direction.

[0080] Further, in this embodiment, when the first torsion arm 122 abuts against the base 110, it indirectly abuts against the base 110 through the first sliding portion 141, so that the first sliding portion 141 can increase the contact area when the first torsion arm 122 abuts against the base 110, thereby making the first torsion arm 122 abut against the base 110 reliably. Similarly, the second sliding portion 142 can increase the contact area when the second torsion arm 123 abuts against the base 110, thereby making the second torsion arm 123 abut against the base 110 reliably.

[0081] In other embodiments, the first sliding portion 141 and the second sliding portion 142 may not be cross bars, but may be, for example, balls, which are connected to the first torsion arm 122 / the second torsion arm 123 by ball joints.

[0082] Please refer to Figure 1 and Figure 3 In one embodiment, the number of torsion springs 120 is two, namely, a first torsion spring 120a and a second torsion spring 120b. The first torsion spring 120a and the second torsion spring 120b are arranged at intervals along the axial direction of the spring coils 121 of the first torsion spring 120a and the spring coils 121b of the second torsion spring 120b are arranged at intervals along the axial direction. In addition, the first torsion arm 122a of the first torsion spring 120a is arranged in parallel with the first torsion arm 122b of the second torsion spring 120b. The second torsion arm 123a of the first torsion spring 120a is arranged in parallel with the second torsion arm 123b of the second torsion spring 120b. One end of the first sliding portion 141 is connected to the first torsion arm 122a of the first torsion spring 120a, and the other end is connected to the first torsion arm 122b of the second torsion spring 120b. One end of the second sliding portion 142 is connected to the second torsion arm 123 a of the first torsion spring 120 a , and the other end is connected to the second torsion arm 123 b of the second torsion spring 120 b .

[0083] Specifically, the structure formed by connecting the first torsion arm 122a of the first torsion spring 120a, the first torsion arm 122b of the second torsion spring 120b, and the first sliding portion 141 is roughly "U" shaped. Similarly, the structure formed by connecting the second torsion arm 123a of the first torsion spring 120a, the second torsion arm 123b of the second torsion spring 120b, and the second sliding portion 142 is roughly "U" shaped. It can be seen that the first torsion spring 120a, the second torsion spring 120b, the first sliding portion 141, and the second sliding portion 142 are connected to form an integral torsion elastic structure.

[0084] Since the two first torsion arms 122 (122a, 122b) are connected by the first sliding portion 141, and the two second torsion arms 123 (123a, 123b) are connected by the second sliding portion 142, during the installation of the PCIe card 200, the two first torsion arms 122 (122a, 122b) can move synchronously, the two second torsion arms 123 (123a, 123b) can move synchronously, and the two spring coils 121 (121a, 121b) can undergo elastic torsional deformation synchronously. It can be seen that the overall elastic torsion structure formed by the first torsion spring 120a, the second torsion spring 120b, the first sliding part 141 and the second sliding part 142 not only increases the axial size of the PCIe card compression structure 100 along the spring coil 121, but also enables the first torsion spring 120a and the second torsion spring 120b to move synchronously, thereby facilitating the stable movement direction of the first torsion arm 122 and the second torsion arm 123 during the installation of the PCIe card 200, and enhancing the reliability of the PCIe card compression structure 100.

[0085] Please refer to Figure 1 , Figures 3 to 5 In one embodiment, the PCIe card compression structure 100 further includes: a first sleeve 151 and a second sleeve 152. The first sleeve 151 is sleeved on the first sliding portion 141, and the first sliding portion 141 can slide along the base 110 by rolling the first sleeve 151. The second sleeve 152 is sleeved on the second sliding portion 142, and the second sliding portion 142 can slide along the base 110 by rolling the second sleeve 152.

[0086] Specifically, as described above, when the first torsion arm 122 and the second torsion arm 123 make a relative opening or closing movement, the first sliding portion 141 slides relative to the base 110 along the first direction, and the second sliding portion 142 slides relative to the base 110 along the first direction.

[0087] Since the first sleeve 151 is sleeved on the first sliding part 141, the first sliding part 141 can slide along the first direction by rolling along the base 110 by the first sleeve 151, thereby the first sliding part 141 slides along the first direction, thereby the sliding friction between the first sleeve 151 and the base 110 is replaced by the rolling friction between the first sleeve 151 and the base 110, thereby reducing the friction resistance when the first sliding part 141 slides relative to the base 110. Similarly, since the second sleeve 152 is sleeved on the second sliding part 142, the second sliding part 142 can slide along the first direction by rolling along the base 110 by the second sleeve 152, thereby the second sliding part 142 slides along the first direction, thereby the rolling friction between the second sleeve 152 and the base 110 is replaced by the sliding friction between the second sliding part 142 and the base 110, thereby reducing the friction resistance when the second sliding part 142 slides relative to the base 110.

[0088] Please refer to Figure 1 and Figure 5 In one embodiment, the PCIe card compression structure 100 further includes: a limiting portion 160. The limiting portion 160 is connected to the base 110 and is located on a side of the base 110 close to the torsion spring 120. A slide groove 101 is formed between the limiting portion 160 and the base 110, and the first sliding portion 141 and the second sliding portion 142 are respectively located in the slide groove 101.

[0089] Specifically, the gap between the limiting portion 160 and the base 110 forms the slide groove 101. In this embodiment, there are two limiting portions 160, namely the first limiting portion 160a and the second limiting portion 160b. Therefore, there are also two slide grooves 101. The first limiting portion 160a forms a first slide groove 101a with the base 110, and the second limiting portion 160b forms a second slide groove 101b with the base 110. The first sliding portion 141 cooperates with the first slide groove 101a. The second sliding portion 142 cooperates with the second slide groove 101b.

[0090] Since the first limiting portion 160a is located on the side of the base 110 close to the torsion spring 120, and the first sliding groove 101a is formed between the first limiting portion 160a and the base 110, when the first sliding portion 141 is in the first sliding groove 101a, it is located between the first limiting portion 160a and the base 110, so that the first sliding portion 141 is limited in the second direction by the first limiting portion 160a and the base 110, thereby ensuring that the first sliding portion 141 is reliably connected to the base 110. Similarly, the second sliding portion 142 is limited in the second direction by the second limiting portion 160b and the base 110, thereby ensuring that the second sliding portion 142 is reliably connected to the base 110.

[0091] Please refer to Figure 1 In one embodiment, a socket part 161 is provided at one end of the limiting part 160 along the first direction, and the other end is fixedly connected to the base 110. A limiting groove 162 is provided on the base 110. The socket part 161 is inserted into the limiting groove 162 along the first direction.

[0092] Specifically, combined Figure 1 , Figure 4 as well as Figure 5 , a socket part 161b is provided at one end of the second limiting part 160b along the first direction. A limiting groove 162b is provided on the base 110. The opening of the limiting groove 162b faces the first direction, so the socket part 161b can be inserted into the limiting groove 162b along the first direction and cooperate with the limiting groove 162b. Figure 6 and Figure 7It can be known that the other end of the second limiting portion 160b along the first direction can be fixed to the base 110 through a threaded connector 172. Similarly, the first limiting portion 160a is provided with a socket portion 161a at one end along the first direction. The base 110 is provided with another limiting groove (not shown) that cooperates with the socket portion 161a. The other end of the first limiting portion 160a along the first direction can be fixed to the base 110 through a threaded connector 171. It can be understood that the opening of the other limiting groove is opposite to the opening of the limiting groove 162b.

[0093] Please refer to Figures 1 to 6 In one embodiment, the PCIe card compression structure 100 further includes a support shaft 130, which includes a connecting section 132 and a supporting section 131 arranged along the axial direction and fixedly connected. The connecting section 132 is inserted through the spring coil 121, and the supporting section 131 is used to abut against the PCIe card 200.

[0094] Specifically, the connecting section 132 and the supporting section 131 may be integrally formed. Figure 1 As shown, in this embodiment, there are two connecting segments 132. The two connecting segments 132 are respectively located at both ends of the supporting segment 131. One connecting segment 132 is inserted through the spring coil 121a of the first torsion spring 120a, and the other connecting segment 132 is inserted through the spring coil 121b of the second torsion spring 120b, so that the supporting segment 131 is located between the two spring coils 121 (121a, 121b).

[0095] During the installation of the PCIe card 200, when the spring coil 121 (121a, 121b) abuts against the PCIe card 200, it can indirectly abut against the PCIe card 200 through the support section 131, thereby indirectly providing pressure to the PCIe card 200 through the support section 131, and further, there is no need for the spring coil 121 to directly abut against the PCIe card 200. Since the spring coil 121 is not directly abutted against the PCIe card 200, and since the spring coil 121 is sleeved on the connecting section 132, when the spring coil 121 undergoes elastic torsional deformation, it can rotate relative to the connecting section 132, thereby facilitating the torsional deformation of the spring coil 121. It can be seen from this that by providing the support section 131 and the connecting section 132, on the one hand, pressure can be indirectly provided to the PCIe card 200 through the support section 131, and on the other hand, elastic torsional deformation of the spring coil 121 can be facilitated through the connecting section 132.

[0096] like Figure 1As shown, in one embodiment, the outer diameter of the support segment 131 is greater than the outer diameter of the connecting segment 132, so that when the support segment 131 is pressed on the PCIe card 200, the outer peripheral surface of the support segment 131 is closer to the surface of the PCIe card 200 than the outer peripheral surface of the connecting segment 132, and then there is a certain distance between the outer peripheral surface of the connecting segment 132 and the surface of the PCIe card 200. This distance provides installation space for the spring coil 121, and when the distance is large enough, it can ensure that there is a gap between the spring coil 121 and the surface of the PCIe card 200, which is conducive to the smooth elastic torsional deformation of the spring coil 121.

[0097] Please refer to Figures 1 to 6 In one embodiment, the PCIe card compression structure 100 further includes an anti-slip sleeve 133 sleeved on the supporting section 131 .

[0098] Specifically, Figures 1 to 6 As shown, the outer circumference of the anti-slip sleeve 133 is provided with anti-slip protrusions 134 distributed in an array, so that the outer circumference of the anti-slip sleeve 133 forms a rough surface.

[0099] Since the anti-slip sleeve 133 is sleeved on the support section 131, when the spring coil 121 (121a, 121b) contacts the PCIe card 200, the anti-slip sleeve 133 can indirectly contact the PCIe card 200, thereby pressing the PCIe card 200. Since the outer peripheral surface of the anti-slip sleeve 133 forms a rough surface, the friction between the anti-slip sleeve 133 and the PCIe card 200 can be increased, which is conducive to the anti-slip sleeve 133 reliably pressing the PCIe card 200.

[0100] It can be understood that in other embodiments, the outer peripheral surface of the anti-slip sleeve 133 can also be provided with other anti-slip patterns, not limited to the anti-slip protrusions 134 distributed in an array.

[0101] Please refer to Figure 7 Another embodiment of the present application further provides a computer 10. The computer 10 comprises: a motherboard 300, a PCIe card pressing structure 100 of any of the above embodiments, and a PCIe card 200. The relative positions of the base 110 and the motherboard 300 are fixed. The PCIe card 200 is located between the motherboard 300 and the PCIe card pressing structure 100, one end of the PCIe card 200 is mounted on the motherboard 300, and the other end is pressed by the spring coil 121.

[0102] When the PCIe card pressing structure 100 is used to install the PCIe card 200 on the motherboard 300 of the computer 10, the PCIe card 200 is located between the motherboard 300 and the PCIe card pressing structure 100, and the torsion spring 120 is located between the base 110 and the PCIe card 200. The relative positions of the base 110 and the motherboard 300 are fixed. One end of the PCIe card 200 is installed on the motherboard 300, and the other end is pressed by the spring coil 121. When the PCIe cards 200 of different heights are installed, since the relative position of the base 110 relative to the motherboard 300 is fixed, the spacing between the PCIe cards 200 of different heights and the base 110 is different. When installing PCIe cards 200 of different heights, the spring coil 121 can be abutted against the PCIe card 200, and the first torsion arm 122 and the second torsion arm 123 can be pressed to different degrees by the base 110, so that different distances can be formed between the base 110 and the spring coil 121, thereby adapting to different distances between PCIe cards 200 of different heights and the base 110. It can be seen that the above-mentioned PCIe card pressing structure 100 can adapt to reliably installing PCIe cards 200 of various heights on the mainboard 300.

[0103] Please refer to Figure 7 In one embodiment, the computer 10 further includes: a housing 400 and a mounting portion 500. The housing 400 accommodates the motherboard 300, the PCIe card 200, and the PCIe card compression structure 100. The mounting portion 500 is mounted on the housing 400, and the base 110 is mounted on the mounting portion 500. The base 110 is fixed to the housing 400 by the mounting portion 500, so that the base 110 can be easily installed.

[0104] It is understood that the present application is not limited to fixing the base 110 on the housing 400 by the mounting portion 500. In other embodiments, the relative positions of the base 110 and the mainboard 300 may be fixed by other means, such as fixing the base 110 and the mainboard 300.

[0105] Please refer to Figures 7 to 10 , the number of PCIe cards 200 is at least two, the number of PCIe card pressing structures 100 is at least two, and the PCIe cards 200 correspond to the PCIe card pressing structures 100 one by one. The sizes of at least two PCIe cards 200 along the second direction are different from each other, wherein the second direction is the pressure direction when the spring coil 121 presses the PCIe card 200.

[0106] Specifically, combined Figures 7 to 10It can be known that the computer 10 can be configured with at least two PCIe cards 200 of different heights, for example, two, three, etc. Each PCIe card 200 can be configured with a PCIe card compression structure 100. Since the PCIe card compression structure 100 of the present application can be applicable to the installation of PCIe cards 200 of different heights, at least two PCIe cards 200 can be conveniently installed on the motherboard 300.

[0107] Furthermore, the base 110 of each PCIe card compression structure 100 is respectively installed on the mounting portion 500, so that by fixing the mounting portion 500 on the shell 400, the positions of at least two bases 110 can be fixed at one time, and the installation of at least two PCIe cards 200 can be completed at one time.

[0108] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
