[0005] In one alternative approach, a first connecting hole is provided on the first rod body, and a plurality of second connecting holes are provided on the second rod body along its extension direction. When the first rod body moves to different positions relative to the second rod body, the first connecting hole is connected to different second connecting holes by a first fastener.

[0006] In one alternative embodiment, a insert extends vertically from the first rod, and a plurality of sockets are provided on the second rod along its extension direction. Each socket corresponds to a second connecting hole, and the distance between the corresponding socket and the first connecting hole is equal to the distance between the insert and the first connecting hole. When the first rod moves to different positions relative to the second rod, and the insert is inserted into a socket, the second connecting hole corresponding to that socket is aligned with the first connecting hole.

[0007] In one alternative embodiment, the top ends of the two second fixing rods are provided with a fixing connection portion facing each other, the fixing connection portion having multiple fixing positions at different heights, the first connecting rod can be bridged between fixing positions at any height, and the second connecting rod is bridged between the bottom ends of the two second fixing rods.

[0008] In one alternative approach, multiple fixing positions at different heights include multiple fixing holes arranged along the extension direction of the second fixing rod. When the different fixing holes are connected to both ends of the first connecting rod by the second fastener, the first connecting rod is fixed at different heights.

[0009] In one alternative embodiment, the second fixed rod includes a first inclined rod and a second inclined rod, each forming a hypotenuse of a triangle. Both the first connecting rod and the second connecting rod are bridged between the two first inclined rods. The second inclined rod includes a support rod body and an adjusting rod body, which are slidably connected to the support rod body to different positions and are fixedly connected. The end of the support rod body facing away from the adjusting rod body is rotatably connected to the first fixed rod, and the end of the adjusting rod body facing away from the support rod body is rotatably connected to the first inclined rod. The first fixed rod is rotatably connected to the first inclined rod.

[0010] In one alternative embodiment, the adjusting rod is at least partially telescopically disposed within the support rod, and a strip-shaped hole is provided on one side of the support rod along its extension direction. At least one adjusting hole is provided on the adjusting rod. When the adjusting rod is telescopically extended to different positions relative to the support rod, the different positions of the adjusting hole and the strip-shaped hole are aligned and connected to each other by a third fastener.

[0011] In one alternative embodiment, both the first fixed rod and the first inclined rod have U-shaped cross-sections; the adjusting rod is rotatably connected to the inner wall of the first inclined rod, and the supporting rod, adjusting rod, and first fixed rod are all detachably connected. When the supporting rod and adjusting rod are detached, the adjusting rod can rotate and be housed within the first inclined rod; the first inclined rod is rotatably connected to the inner wall of the first fixed rod, so that the adjusting rod and the first inclined rod can rotate together and be housed within the first fixed rod.

The outer sides of the first connecting rod, the second connecting rod, and the two second fixing rods are used to abut against the edge of the back of the fanless industrial panel PC. Grooves are formed on the inner sides of the second fixing rod and the first connecting rod. The bracket also includes multiple connecting hooks, each hook comprising a body, a latch, and a locking element. The latch is located on one side of the body, and the locking element passes through the body and is threadedly connected to the body. The latch is used to hook into the hook interface. The multiple bodies abut against the side walls of the grooves formed on the second fixing rod and the first connecting rod, respectively. The locking element is tightened and abuts against the bottom wall of the groove to fix the fanless industrial panel PC to the bracket, and to expose the heat dissipation fins from the space formed by the second fixing rod, the first connecting rod, and the second connecting rod.

[0014] The bracket provided in this application embodiment uses two opposing triangular fixing frames as support components to utilize the stability of triangles and ensure a firm and reliable support for the tablet computer. Parallel first and second connecting rods are bridged between the second fixing rods in the two fixing frames, so that the first connecting rod, the second connecting rod, and the two second fixing rods enclose a rectangle. This rectangle, connected to at least a portion of the tablet computer's edges, fixes the tablet computer to the bracket in an inclined state. After fixing, a large area in the middle of the back of the tablet computer can be exposed from the space enclosed by the rectangle, thereby ensuring that the tablet computer's heat dissipation performance is not affected after being installed on the bracket, thus ensuring the rigorous and reliable test results of the tablet computer.

[0037] Tablets are typically used handheld or tilted on a stand, which provides ample space for heat dissipation in the back cover. However, during factory testing, tablets are often placed directly on a table or clamped onto a test bench. This obstructs the space on the back of the tablet, significantly reducing its heat dissipation efficiency. Consequently, the accuracy and reliability of the test results are also affected by the reduced heat dissipation efficiency.

[0038] To ensure rigorous and reliable test results, this application proposes a tablet computer testing stand. This stand not only positions and secures the tablet computer in a more practical way but also provides ample ventilation space on the back of the tablet, thus guaranteeing the accuracy and reliability of the test results. Furthermore, to ensure compatibility with tablet computers of different sizes, this application also incorporates an adjustable design to support and secure tablets of various specifications and models.

[0039] Specifically, please refer to the following: Figures 1 to 3 , Figure 1 and Figure 2 The image shows the usage scenarios of the tablet computer test stand from both front and back views. Figure 3 It shows the basis Figure 2 The structure of the explosion is shown in the figure. As shown, the bracket 100 includes a fixing bracket 110 and a connecting bracket 120.

[0040] The mounting bracket 110 includes two opposing brackets, each bracket 110 comprising a first fixing rod 111 and a second fixing rod 112 connected in a triangular configuration. The first fixing rod 111 forms the base of the triangle; that is, in practical applications, the first fixing rod 111 is used to attach and place the bracket on a desktop or test bench. The second fixing rod 112 is bent to form the two hypotenuses of the triangle.

[0041] The connecting frame 120 includes a first connecting rod 121 and a second connecting rod 122. Both the first connecting rod 121 and the second connecting rod 122 are bridged between two second fixed rods 112. The first connecting rod 121 can be bridged at different heights between the two second fixed rods 112, and the first connecting rod 121 is parallel to the second connecting rod 122 at any height. This arrangement allows the distance between the first connecting rod 121 and the second connecting rod 122 to be adjustable, thereby adapting to the height of tablet computers of different specifications and models.

[0042] It is understandable that different models of tablet computers have different heights and widths. In addition to the adjustable distance between the first connecting rod 121 and the second connecting rod 122 to accommodate different heights, the lengths of the first connecting rod 121 and the second connecting rod 122 are also adjustable to accommodate the widths of different models of tablet computers.

[0043] like Figure 3 As shown, the first connecting rod 121 includes a first rod body 1211 and a second rod body 1212. The first rod body 1211 and the second rod body 1212 are movable to different positions and fixedly connected, so that the length of the first connecting rod 121 formed by the combination of the first rod body 1211 and the second rod body 1212 is adjustable. Similarly, the second connecting rod 122 includes a third rod body 1221 and a fourth rod body 1222. The third rod body 1221 and the fourth rod body 1222 are movable to different positions and fixedly connected, so that the length of the second connecting rod 122 is adjustable.

[0044] At least a portion of the second fixing rod 112, the first connecting rod 121, and the second connecting rod 122 is used to connect to the back of the tablet computer 200 to fix the tablet computer 200 to the bracket 100. Based on the adjustable distance between the first connecting rod 121 and the second connecting rod 122 described above, and the adjustable length of the first connecting rod 121 and the second connecting rod 122 themselves, the rectangle formed by the first connecting rod 121, the second connecting rod 122, and the two second fixing rods 112 can have all its side lengths adjusted, thereby adapting to tablet computers 200 of different sizes and achieving support and fixation during testing of tablet computers 200 of different sizes.

[0045] like Figure 2 As shown, after the tablet computer 200 is fixed to the bracket 100, the middle position of the back of the tablet computer 200 will be exposed from the space formed by the second fixing rod 112, the first connecting rod 121 and the second connecting rod 122. This makes the back of the tablet computer 200 unobstructed and has a wide heat dissipation space, thus ensuring its heat dissipation capacity during testing and ensuring that the test results are accurate and reliable.

[0046] In specific implementations, all the aforementioned rods can be made of metal profiles, and they can be connected to each other by drilling holes and inserting fasteners (such as rivets, screws, etc.). Of course, in some other embodiments, the aforementioned rods can also be made of columnar metal rods or plastic rods, and can be assembled and connected to each other by integral molding, snap-fit, or other methods.

[0047] In summary, the bracket 100 provided in this application embodiment uses two opposing triangular fixing frames 110 as support components to utilize the stability of triangles and ensure a firm and reliable support for the tablet computer 200. Parallel first connecting rods 121 and second connecting rods 122 are bridged between the second fixing rods 112 in the two fixing frames 110, so that the first connecting rod 121, second connecting rod 122, and two second fixing rods 112 enclose a rectangle. This rectangle, by connecting to at least a portion of the edges of the tablet computer 200, fixes the tablet computer 200 to the bracket 100 in an inclined state. After fixing, a large area in the middle of the back of the tablet computer 200 can be exposed from the space enclosed by the rectangle, thereby ensuring that the heat dissipation performance of the tablet computer 200 is not affected after it is installed on the bracket 100, thus ensuring the rigorous and reliable test results of the tablet computer 200.

[0048] Regarding the adjustable length structure of the first connecting rod 121, this application proposes an implementation method, please refer to [link / reference needed]. Figure 4 The figure shows the three-dimensional structure of the first connecting rod 121. As shown in the figure, the first rod 1211 has a first connecting hole 1211a, and the second rod 1212 has a plurality of second connecting holes 1212a along its extension direction. When the first rod 1211 moves to different positions relative to the second rod 1212, the first connecting hole 1211a is connected to different second connecting holes 1212a by a first fastener (not shown, such as a screw, rivet, or pin), so that the first rod 1211 and the second rod 1212 are fixedly connected to each other, thereby keeping the first connecting rod 121 at its current length.

[0049] Considering that before connecting the first connecting hole 1211a and the second connecting hole 1212a with the first fastener, it is necessary to ensure that the first connecting hole 1211a and the second connecting hole 1212a are aligned, this operation is rather cumbersome and will affect the convenience of adjusting the length of the first connecting rod 121.

[0050] In this regard, further, such as Figure 4As shown, a insert 1211b can extend vertically from the first rod 1211, and a plurality of sockets 1212b are provided on the second rod 1212 along its extension direction. Each socket 1212b corresponds to a second connecting hole 1212a. The distance between the corresponding socket 1212b and the second connecting hole 1212a is equal to the distance between the insert 1211b and the first connecting hole 1211a. With this configuration, when the first rod 1211 moves to different positions relative to the second rod 1212, and the insert 1211b is inserted into a certain socket 1212b, the second connecting hole 1212a corresponding to the socket 1212b is exactly aligned with the first connecting hole 1211a. Moreover, the first rod 1211 and the second rod 1212 will not undergo relative displacement, which would cause the second connecting hole 1212a to misalign with the first connecting hole 1211a again. Thus, the first connecting hole 1211a and the second connecting hole 1212a can be easily connected to each other by the first fastener, making it convenient and quick to adjust the length of the first connecting rod 121.

[0051] Specifically, in Figure 4 In the specific embodiment shown, the insert 1211b is disposed at the end of the first rod 1211 to ensure that when the insert 1211b is inserted into the corresponding socket 1212b, it is easy to observe whether the two are aligned, making the operation more convenient. Since the insert 1211b is located at the end of the first rod 1211, correspondingly, Figure 4 In the middle, each socket 1212b has a one-to-one correspondence with the second connecting hole 1212a adjacent to its left.

[0052] Of course, in some other embodiments, the insert 1211b can also be located in the middle part of the first rod 1211, and the position of the socket 1212b can be adjusted accordingly. In short, it is sufficient to ensure that the positional relationship between the one-to-one corresponding socket 1212b and the second connecting hole 1212a is consistent with the positional relationship between the insert 1211b and the first connecting hole 1211a.

[0053] In addition to the arrangement shown in the attached diagram, the first rod 1211 and the second rod 1212 can also be telescopically connected within the second rod 1212 to adjust the length of the first connecting rod 121. Furthermore, the first rod 1211 can be provided with automatically popping elastic posts, while the second rod has multiple locking holes arranged on it. When the first rod 1211 is extended or retracted to a predetermined position, its elastic posts automatically pop out and lock into the corresponding locking holes, thus maintaining the first connecting rod 121 at its current length. For the next adjustment, simply press the elastic posts into the locking holes and slide the first rod 1211 to extend or retract again.

[0054] The second connecting rod 122 can adjust its length in the same way as the first connecting rod 121 provided in any of the above embodiments, and the specific details will not be elaborated here.

[0055] Regarding the structure related to the height adjustment of the first connecting rod 121, this application proposes an implementation method, please refer to [link / reference needed]. Figure 5 The figure shows the exploded structure of the bracket from the front view. As shown in the figure, the top ends of the two second fixing rods 112 can be provided with fixing connection parts 1121 facing each other. The fixing connection parts 1121 have multiple fixing positions at different heights. Specifically, the multiple fixing positions at different heights can be multiple fixing holes 1121a arranged along the extension direction of the second fixing rods 112, as shown in the figure. When the different fixing holes 1121a are connected to the first connecting rod 121 by the second fastener (not shown in the figure, but can also be screws, rivets, pins, etc.), the first connecting rod 121 is fixed at different heights.

[0056] exist Figure 5 In the specific embodiment shown, in order to prevent the first connecting rod 121 from rotating, two mounting holes 1213 are provided at both ends of the first connecting rod 121. Two adjacent fixing holes 1121a are connected to the two mounting holes 1213 one by one through the second fastener.

[0057] Furthermore, considering the impact of manufacturing errors, two adjacent fixing holes 1121a may not be able to be perfectly aligned with two assembly holes 1213. Therefore, fixing holes 1121a can also be set to be elliptical or strip-shaped to provide more margin to ensure that two adjacent fixing holes 1121a can be effectively connected to two assembly holes 1213 through a second fastener.

[0058] In addition to using a plurality of fixed holes 1121a arranged in a row, the fixed connection part 1121 can also be an elongated hole opened on the second fixed rod 112 and in the same direction of extension as the second fixed rod 112. Different positions of the elongated hole form fixed positions at different heights. Correspondingly, the first connecting rod 121 can be bridged between fixed positions at any height on both sides of the elongated hole, and is connected to the first connecting rod 121 by the second fastener passing through the elongated hole to fix the first connecting rod 121.

[0059] The second connecting rod 122 is bridged between the bottom ends of the two second fixed rods 112. Specifically, the second connecting rod 122 can be fixedly connected to the second fixed rod 112 by passing a screw through the second fixed rod 112 and connecting it with the second connecting rod 122, or the second connecting rod 122 can be directly welded to the second fixed rod 112.

[0060] Different testing scenarios or different technicians' testing habits may require different tilt angles for the tablet computer 200. Therefore, this application further includes an adjustable mounting angle design for the tablet computer 200. Please refer to [link / reference] for details. Figure 6 The figure shows the three-dimensional structure of the bracket from the rear view. As shown in the figure, the second fixing rod 112 includes a first inclined rod 113a and a second inclined rod 113b. The first inclined rod 113a and the second inclined rod 113b each form a hypotenuse of a triangle. The first connecting rod 121 and the second connecting rod 122 are both bridged between the two first inclined rods 113a.

[0061] The second inclined rod 113b includes a support rod 1131 and an adjusting rod 1132. The adjusting rod 1132 and the support rod 1131 can slide relative to each other to different positions and be fixedly connected. The two can be assembled in the same way as the first rod 1211 and the second rod 1212 provided in any of the above embodiments. This arrangement realizes the length adjustment of the second inclined rod 113b itself.

[0062] The length of the second diagonal rod 113b is adjustable, meaning that the length of one side of the triangle is adjustable. Accordingly, to ensure that the first fixed rod 111, the first diagonal rod 113a, and the second diagonal rod 113b can still connect to form a triangle, the interior angles of the triangle also need to be adaptively changed. Based on this, the end of the support rod 1131 away from the adjusting rod 1132 is rotatably connected to the first fixed rod 111, the end of the adjusting rod 1132 away from the support rod 1131 is rotatably connected to the first diagonal rod 113a, and the first fixed rod 111 and the first diagonal rod 113a are also rotatably connected.

[0063] With this setting, when the adjusting rod 1132 is slid to different positions relative to the supporting rod 1131, the included angle between the first fixed rod 111 and the first inclined rod 113a used to install the tablet computer 200 changes accordingly, thereby realizing the adjustment of the tilt angle of the tablet computer 200 when supporting it, so as to adapt to the needs of different test scenarios or the test habits of different technicians.

[0064] exist Figure 6In the specific embodiment shown, in order to achieve stepless adjustment of the tilt angle of the tablet computer 200 and the stability of the connection between the adjusting rod 1132 and the support rod 1131, the adjusting rod 1132 is at least partially telescopically disposed within the support rod 1131. The inner wall of the support rod 1131 limits the contact of the adjusting rod 1132, preventing the adjusting rod 1132 from tilting relative to the support rod 1131 (tilting would cause the fixing frame 110 to form a quadrilateral), thus avoiding triangular structure failure and ensuring the reliability of the fixing frame 110 support. A strip-shaped hole 1131a is provided on one side of the support rod 1131 along its extending direction, and at least one adjusting hole 1132a is provided on the adjusting rod 1132. When the adjusting rod 1132 extends or retracts to different positions relative to the supporting rod 1131, the different positions of the adjusting hole 1132a and the strip hole 1131a are aligned and connected to each other by a third fastener (not shown, such as a screw, etc.) so that the adjusting rod 1132 can be extended or retracted to any position and then fixed in place.

[0065] exist Figure 6 In the specific embodiment shown, a plurality of adjustment holes 1132a are arranged on the adjustment rod 1132. When the insertion length of the adjustment rod 1132 into the support rod 1131 is long, all the adjustment holes 1132a located in the support rod 1131 can be connected to the strip hole 1131a through the third fastener to fully ensure the stability of the connection between the adjustment rod 1132 and the support rod 1131.

[0066] To facilitate the storage of the bracket 100, this application further incorporates a foldable design for the fixing frame 110; please refer to [link / reference needed] for details. Figure 7 and Figure 8 The figure shows the structure of the fixing frame 110 in its unfolded and folded states. As shown, the cross-sections of the first fixing rod 111 and the first inclined rod 113a are both U-shaped; for example, they can both be made of U-shaped aluminum profiles. The adjusting rod 1132 is rotatably connected to the inner wall of the first inclined rod 113a. The support rod 1131, the adjusting rod 1132, and the first fixing rod 111 can all be detachably connected; for example, they can all be detachably connected using threaded fasteners.

Specifically, it can be bridged between the bottom ends of the two support rods 1131 as shown in the figure, or it can be bridged between the middle sections of the two support rods 1131. After bridging the two support rods 1131 with the third connecting rod 123, the connection between the two fixing frames 110 can be further strengthened, thereby significantly improving the overall structural strength of the stand 100 and ensuring its reliability in supporting the tablet computer 200.

[0071] like Figure 3 As shown, the third connecting rod 123 includes a fifth rod 1231 and a sixth rod 1232. The fifth rod 1231 and the sixth rod 1232 can be moved to different positions and fixedly connected to adapt to the width of tablet computers of different specifications. The assembly method between the fifth rod 1231 and the sixth rod 1232 can be the same as the assembly method between the first rod 1211 and the second rod 1212 mentioned above, and will not be described in detail here.

[0072] Tablet PC Figure 2 and Figure 3 The fanless industrial tablet PC shown has a heat dissipation fin 210 protruding from the center of its back, and a hook interface 220 located at the edge of the back. To facilitate easier support and fixation of the stand 100 for such a fanless industrial tablet PC, a further embodiment is proposed. Specifically, as follows... Figure 2 and Figure 3As shown, grooves 130 can be formed on the inner sides of both the second fixing rod 112 and the first connecting rod 121. In the specific embodiment shown in the figure, both the second fixing rod 112 and the first connecting rod 121 are made of U-shaped profiles, and the shape of the profile itself forms the grooves 130. For other shapes of second fixing rods 112 and first connecting rods 121, smaller grooves 130 can also be formed on them.

[0073] The bracket 100 also includes multiple connecting hooks 140, such as Figure 9 As shown Figure 2 In the enlarged structure at point A, the connecting hook 140 includes a body 141, a latch 142, and a locking member 143. The latch 142 is located on one side of the body 141, and the locking member 143 passes through the body and is connected to the body 141 by a thread.

[0074] When mounting the fanless industrial panel PC on the bracket 100, first hook 142 into the hook interface 220, then abut the main body 141 against the side wall of the groove 130 formed on the second fixing rod 112 and the first connecting rod 121. At the same time, the edge of the back of the fanless industrial panel PC will abut against the outer side of the first connecting rod 121, the second connecting rod 122, and the two second fixing rods 112. Next, tighten the locking member 143 so that it abuts against the bottom wall of the groove 130. Thus, by utilizing the abutment of the outer side of the back edge of the fanless industrial panel PC and the abutment of the inner side of the locking member 143, the edge of the fanless industrial panel PC is reliably connected to the first connecting rod 121 and the second fixing rod 112 by clamping, and this connection method is convenient for assembly and disassembly.
