[0054] In the related art, a board card test platform is usually used to support the board card to be tested. On the one hand, due to the adverse effects of manufacturing errors of the test platform, assembly matching errors of the test platform and the board card to be tested, and the like, in the actual use process, the board card to be tested cannot be aligned and reliably connected with the CPU mainboard. On the other hand, the test platform is usually used to test a single board card, and it is difficult to adjust the height of the test platform or the operation, and the universality is poor.

[0055] The purpose of the present disclosure is to provide a board card support platform 100 and a board card test device, which can realize multi-stage adjustment of the board card to be tested 400 in the vertical direction Z, can effectively reduce the adverse effects caused by the manufacturing errors of the support platform, the assembly matching errors of the support platform and the board card to be tested 400, and the like, and improve the connection effect of the board card to be tested 400 and the CPU mainboard 220.

[0056] In order to achieve the above purpose, as shown in the accompanying drawings, Figures 1 to 12As shown, according to the first aspect of the present disclosure, a board card supporting platform 100 is provided for supporting a board card 400 to be tested, such as a display card. Wherein, the board card 400 to be tested is usually placed horizontally and connected to a CPU mainboard 220 fixed on a CPU mounting bracket 210 through a PCIE connector, and the board card supporting platform 100 can support the board card 400 to be tested in the vertical direction Z to avoid uneven force or tilting of the board card 400 to be tested. The board card supporting platform 100 comprises a base 110, a first supporting frame 120 and a second supporting frame 130. Wherein, the first supporting frame 120 is adjustably connected to the base 110 in the vertical direction Z; the second supporting frame 130 is used for supporting the board card 400 to be tested and is adjustably connected to the first supporting frame 120 in the vertical direction Z.

[0057] Through the above technical solution, i.e. the board card supporting platform 100 of the present disclosure, comprising a base 110, a first supporting frame 120 and a second supporting frame 130, wherein the first supporting frame 120 is adjustably connected to the base 110, and the second supporting frame 130 is adjustably connected to the first supporting frame 120, and the second supporting frame 130 is used for supporting the board card 400 to be tested, so as to realize multi-stage adjustment of the board card 400 to be tested in the vertical direction Z, which can effectively reduce the adverse effects caused by manufacturing errors of the supporting platform, assembly errors of the supporting platform and the board card 400 to be tested, etc., improve the connection effect of the board card 400 to be tested and the CPU mainboard 220, and has better versatility.

[0058] It should be noted that the board card supporting platform 100 of the present disclosure can realize two-stage adjustment through the position adjustment of the first supporting frame 120 relative to the base 110 in the vertical direction Z, and the adjustment of the second supporting frame 130 relative to the first supporting frame 120 in the vertical direction Z, which improves the adjustment accuracy of the board card 400 to be tested supported on the second supporting frame 130, and is used to compensate for the manufacturing errors of the board card supporting platform 100 or the assembly errors between components, so as to better connect to the CPU mainboard 220. It can be understood that in addition to the above first supporting frame 120 and second supporting frame 130, other supporting frames that can adjust the position in the vertical direction Z relative to the two can be arranged between the base 110 and the first supporting frame 120, and the first supporting frame 120 and the second supporting frame 130, to realize more stages of adjustment of the board card supporting platform 100. The specific number can be designed according to actual needs, which will not be described here.

[0059] In some embodiments, the adjustment distance of the first support frame 120 relative to the base 110 is greater than the adjustment distance of the second support frame 130 relative to the first support frame 120. In this way, the first support frame 120 is adjusted in the vertical direction Z relative to the base 110 to enable the first support frame 120 to achieve coarse adjustment of the entire board card support platform 100 in the vertical direction Z, and the second support frame 130 is adjusted in the vertical direction Z relative to the first support frame 120 to enable the second support frame 130 to achieve fine adjustment of the entire board card support platform 100 in the vertical direction Z. Through the two position adjustments, both adjustment efficiency and adjustment accuracy are satisfied.

[0060] The first support frame 120 and the second support frame 130 can be constructed in any suitable structure, such as Figure 1 As shown in the drawings, in some embodiments of the present disclosure, the first support frame 120 includes two first support plates 121 spaced apart along the first direction X, and an intermediate support plate 122 connected to the two first support plates 121, respectively. The two first support plates 121 are respectively connected to the base 110 in a position-adjustable manner.

[0061] The base 110 can also be constructed in any suitable structure, and in some embodiments, the base 110 can include a bottom plate 111 and two vertical plates 112 connected to the bottom plate 111, respectively, and the two vertical plates 112 are spaced apart along the first direction X. The two first support plates 121 are respectively connected to the two vertical plates 112 in a position-adjustable manner, thereby achieving the position adjustment of the first support frame 120 relative to the base 110 in the vertical direction Z.

[0062] The position adjustment mode between the first support plate 121 and the base 110 can be any suitable mode, such as Figures 2 to 4 As shown in the drawings, in some embodiments, the first support plate 121 is formed with a first mounting portion; the base 110 is formed with a plurality of second mounting portions capable of corresponding to the first mounting portion and spaced apart in the vertical direction Z; the first mounting portion is connected by cooperating with different second mounting portions in the plurality of second mounting portions to adjust the height of the first support frame 120.

[0063] The first mounting part can be a mounting hole, slot, or buckle provided in the first support plate 121. The second mounting part can be multiple mounting holes, buckles, or slots provided in the vertical plate 112 of the base 110. For example, when the first mounting part is a slot, the second mounting part can be multiple buckles arranged at intervals. By installing the buckles in different buckles, the height of the first support frame 120 in the vertical direction Z can be adjusted.

[0064] The first and second mounting sections can be constructed using any suitable structure, such as... Figure 2 , Figure 3 and Figure 4 As shown, in some optional embodiments, the first mounting portion includes at least two first mounting holes 1211 spaced apart along the second direction Y on the first support plate 121; the second mounting portion includes a plurality of first adjustment holes 1101 spaced apart along the vertical direction Z on the base 110 and capable of correspondingly engaging with the first mounting holes 1211. The first mounting portion may include at least two first mounting holes 1211, and the second mounting portion may include a plurality of first adjustment holes 1101. The plurality of first adjustment holes 1101 are spaced apart in the vertical direction Z, and by engaging with the first mounting holes 1211 at different first adjustment holes 1101, the position of the first support frame 120 relative to the base 110 in the vertical direction Z can be adjusted to meet the requirements of the test board 400 with different height requirements.

[0065] Understandably, the first support frame 120 (first support plate 121) can be connected to the base 110 (vertical plate 112 of base 110) by sequentially passing the locking element 150 (e.g., screw or bolt assembly) through the first mounting hole 1211 and the first adjustment hole 1101. The first mounting hole 1211 and the first adjustment hole 1101 can be through holes, or one of them can be set as a screw hole.

[0066] It should be noted that there may be multiple first mounting holes 1211 and first adjustment holes 1101, and at least some of the first mounting holes 1211 may correspond to at least some of the first adjustment holes 1101 at different positions in the vertical direction Z, and be connected and fixed by locking member 150, thereby realizing the height adjustment of the first support frame 120 and the base 110.

[0067] In some embodiments, the base 110 and the first support frame 120 may be made of wood, such as bakelite. Therefore, a metal anti-wear layer may be provided in the first mounting hole 1211 and the first adjustment hole 1101. For example, riveting may be used to arrange rivets with through holes in the first mounting hole 1211 and the first adjustment hole 1101 to improve the strength of the first mounting hole 1211 and the first adjustment hole 1101 and avoid damage to the hole structure during disassembly and assembly.

[0068] The first mounting holes 1211 are multiple, and two first mounting holes 1211 spaced apart in the vertical direction Z form an installation group; the installation groups are arranged in multiple in the second direction Y; the first adjustment holes 1101 are multiple, and two first adjustment holes 1101 spaced apart in the vertical direction Z form a matching group capable of being matched and connected with the installation group; the matching groups are arranged in multiple in the second direction Y and are different in position in the vertical direction Z. As shown in Figure 2 and Figure 3 In some embodiments, each first support plate 121 can be provided with two rows of first mounting holes 1211 spaced apart in the vertical direction Z near the base 110, and two first mounting holes 1211 corresponding in the vertical direction Z form an installation group; wherein a part of the installation groups are located on one side of the first support plate 121 center line in the second direction Y, and another part of the installation groups are located on the other side of the first support plate 121 center line in the second direction Y; at the same time, as shown in Figure 4 The vertical plate 112 of the base 110 is formed with multiple first adjustment holes 1101 arranged in the vertical direction Z, wherein two first adjustment holes 1101 corresponding in the vertical direction Z form a matching group, a part of the matching groups are located on one side of the vertical plate 112 center line in the second direction Y for matched and connected with the corresponding installation group, and another part of the matching groups are located on the other side of the vertical plate 112 center line in the second direction Y for matched and connected with the corresponding installation group.

[0069] Specifically, as shown in Figure 2 and Figure 4As shown, eight mounting groups are formed on the first support plate 121, four of which are located on the left side and arranged in sequence from the left edge to the center line direction, and four of which are located on the right side and arranged in sequence from the right edge to the center line direction; and eight matching groups are formed on the vertical plate 112 of the base 110, four of which are located on the left side and arranged in sequence from the left edge to the center line direction and gradually to the direction of the second support frame 130 in the vertical direction Z, and four of which are located on the right side and arranged in sequence from the right edge to the center line direction and also gradually to the direction of the second support frame 130 in the vertical direction Z. The outermost two mounting groups on the first support plate 121 can be connected to the outermost two matching groups on the vertical plate 112 to achieve support at the lowest height position; the two mounting groups (second mounting groups on the left and right sides) close to the outside on the first support plate 121 can be connected to the two matching groups (second matching groups on the left and right sides) close to the outside on the vertical plate 112 of the base 110 to achieve support at the second height position; the two mounting groups (third mounting groups on the left and right sides) close to the inside on the first support plate 121 can be connected to the two matching groups (third matching groups on the left and right sides) close to the inside on the vertical plate 112 of the base 110 to achieve support at the third height position; and the innermost two mounting groups (fourth mounting groups on the left and right sides) on the first support plate 121 can be connected to the innermost two matching groups (fourth matching groups on the left and right sides) on the vertical plate 112 of the base 110 to achieve support at the highest height position.

[0070] It should be noted that while the first support plate 121 on one side is adjusted to correspond to the position of the vertical plate 112, the position of the first support plate 121 on the other side is also adjusted to correspond.

[0071] In order to facilitate movement and adjustment of the first support frame 120, as shown in Figure 2 and Figure 3 As shown, in some embodiments, a handle portion 1213 is formed on the first support plate 121. Among them, one handle portion 1213 is formed on each of the two upper first support plates 121, wherein the handle portion 1213 can be constructed in any suitable structure, for example, the handle portion 1213 can be a waist-shaped hole formed at the upper position of the first support plate 121, and the user can move the entire board card support platform 100 by inserting his hand into the waist-shaped hole, or can adjust the first support plate 121 upward or downward by inserting his hand into the waist-shaped hole. In addition, the handle portion 1213 can also be a handle mounted on the first support plate 121, which can also achieve the above-mentioned movement or adjustment function.

[0072] In some embodiments, the second support frame 130 comprises a second support plate 131, which is movably connected to the middle support plate 122 through an adjusting assembly, so that the second support plate 131 can move relative to the middle support plate 122 in the vertical direction Z. The second support plate 131 is used to support the board card 400 to be tested, and a corresponding structure for cooperating with the board card 400 to be tested can be arranged thereon. The adjusting assembly is used to connect the second support plate 131 and the middle support plate 122 of the first support frame 120, so as to realize distance adjustment between the second support plate 131 and the middle support plate 122, i.e. distance adjustment in the vertical direction Z.

[0073] The adjusting assembly can be constructed in any suitable structure, such as Figure 5 As shown in some embodiments, the adjusting assembly comprises a screw 141 and two nuts 142; one end of the screw 141 is fixedly connected to the second support plate 131, the middle support plate 122 is provided with an adjusting hole (not shown in the figure), the screw 141 is arranged in the adjusting hole, and the two nuts 142 are connected to the screw 141, one nut 142 is located on the side of the middle support plate 122 away from the second support plate 131 and abuts against the middle support plate 122, and the other nut 142 is located on the side of the middle support plate 122 close to the second support plate 131 and abuts against the middle support plate 122.

[0074] The screw 141 can pass through the second support plate 131 through the through hole arranged on the second support plate 131, and the screw 141 is fixedly connected with the second support plate 131 through the nut 142 arranged on the other side. Of course, the screw 141 can also be fixedly connected with the second support plate 131 in other ways. The adjusting hole for the screw 141 to pass through is formed on the middle support plate 122, and one nut 142 connected with the screw 141 is arranged on each side of the middle support plate 122, and the two nuts 142 respectively abut against the middle support plate 122, so as to realize position fixing after position adjustment of the second support plate 131. When the position needs to be adjusted, the two nuts 142 can be turned, then the extension length of the screw 141 is changed, and after the adjustment is completed, the two nuts 142 are locked.

[0075] In the above embodiments, the second support plate 131 can be slightly lifted through the up and down adjustment of the two nuts 142, and the cooperation of the two nuts 142 can also realize self-locking of the second support plate 131, so as to avoid the up and down shaking of the second support plate 131 during the test.

[0076] It should be noted that a plurality of adjusting assemblies can be arranged between the second support plate 131 and the middle support plate 122, and the overall movement of the second support plate 131 relative to the middle support plate 122 can be realized by adjusting the plurality of adjusting assemblies respectively.

[0077] To stabilize the position adjustment between the second support plate 131 and the intermediate support plate 122, in some embodiments, the joint between the second support plate 131 and the first support plate 121 is further provided with a guide structure for guiding the movement of the second support plate 131. By providing the guide structure between the second support plate 131 and the first support plate 121, the smooth movement of the second support plate 131 in the vertical direction Z can be ensured when adjusting the movement of the second support plate 131.

[0078] It should be noted that the guide structure can be constructed in any suitable structure, for example, as shown in Figure 1 and Figure 2 In some embodiments, the guide structure can include one of the guide groove 1212 and the guide protrusion 1311 provided on the second support plate 131, and the other one of the guide groove 1212 and the guide protrusion 1311 provided on the first support plate 121. The guide structure can include the specific forms of the guide groove 1212 and the guide protrusion 1311. For example, the second support plate 131 can be provided with the guide protrusion 1311, and the first support plate 121 of the first support frame 120 can be provided with the guide groove 1212 matched with the guide protrusion 1311. When the second support plate 131 moves relative to the first support frame 120 (the intermediate support plate 122), the guide protrusion 1311 and the guide groove 1212 can play a guiding role, improving the movement stability of the second support frame 130.

[0079] In other embodiments, the second support plate 131 can be provided with the guide groove 1212, and the first support plate 121 of the first support frame 120 can be provided with the guide protrusion 1311 matched with the guide groove 1212. When the second support plate 131 moves relative to the first support frame 120 (the intermediate support plate 122), the guide protrusion 1311 and the guide groove 1212 can also play a guiding role, improving the movement stability of the second support frame 130.

[0080] It should be noted that the guide protrusion 1311 and the guide groove 1212 can be multiple and one-to-one correspondence, further improving the guiding effect.

[0081] It can be understood that the above-mentioned guide structure is exemplary, and the guide structure can also adopt the structure form of a sliding rail and a sliding block, or can also adopt the structure form of a guide column and a guide sleeve, which will not be described here.

[0082] In order to fix the board card 400 to be tested or the heat dissipation back plate 320 of the board card 400, as shown in Figure 1As shown, in some embodiments, the second support frame 130 includes a fixing hole 1312 and / or a positioning part 1313. For example, the second support frame 130 may be provided with a fixing hole 1312, which can fix the board 400 to be tested, improving the reliability of its connection with the CPU motherboard 220. The second support frame 130 may also be provided with a positioning part 1313 for positioning the board 400 to be tested before fixing, improving assembly efficiency. It is understood that there can be multiple fixing holes 1312, the number of which can be determined by referring to the number of corresponding structures on the board 400 or the heat sink backplate 320. In addition, the positioning part 1313 may be a stepped blind hole corresponding to the fixing hole 1312, which can cooperate with a small protrusion on the heat sink backplate 320 connected to the board 400 to achieve pre-positioning before fixing.

[0083] The 400 board under test sometimes uses a 330 cooling fan for cooling, such as... Figure 1 As shown, in some embodiments, the second support frame 130 also forms a fan avoidance portion 1314, which can be configured as a notch provided on the second support plate 131 to avoid the cooling fan 330 installed on the back of the board 400 to be tested.
