[0002] With the advancement of technology, electronic information equipment is becoming increasingly modular and integrated. These devices typically consist of a chassis and multiple board modules, which are installed separately within the chassis to ensure proper function. For example, in a tester, the chassis typically houses multiple board modules in parallel, with their connectors plugged into the chassis backplane. These board modules are then used to test the performance of electronic components.

[0003] Due to the influence of the chassis, the distance between two adjacent board modules is small. When the board module needs to be pulled out of the chassis, the operating space of the board module is too small to perform the board module removal operation. In addition, the board module removal and removal is easily damaged by using auxiliary tools such as screwdrivers. Summary of the Invention

[0039] The technical solutions provided by the embodiments of this application will be introduced below with reference to the drawings.

[0040] Refer to Figures 1-3 As shown, this application provides a board card extraction assisting mechanism 100. The board card extraction assisting mechanism 100 includes a rotating member 110 and a lever 120. The board card extraction assisting mechanism 100 is used for the auxiliary disassembly and extraction operation of the board card 300 on the chassis 200. The chassis 200 has a card slot 210. The board card 300 includes a panel 310 and a functional board 320. The panel 310 is provided with a lifting hole 311. The board card 300 is vertically inserted into the card slot 210 so that the functional board 320 is located inside the chassis 200, and the panel 310 overlaps the opening end of the card slot 210. The installation and fixation of the board card 300 on the chassis 200 are realized through the panel 310. Among them, in this application, the board card 300 can be a printed circuit board (PCB). Of course, in other feasible embodiments, the board card 300 can also be an integrated structure such as a main board, a sound card, a graphics card, etc., or the board card 300 is other electrical components. The specific type of the board card 300 is not limited in this application.

[0041] The rotating member 110 is rotatably mounted on the chassis 200. For example, the rotating member 110 is directly mounted on the chassis 200 so that the rotating member 110 can rotate relative to the chassis 200; or the rotating member 110 is indirectly mounted on the chassis 200 via other components so that the rotating member 110 can rotate relative to the chassis 200. In this case, the end of the rotating member 110 away from its own rotation axis is initially positioned within the chassis 200. That is, when no operation is performed on the rotating member 110, the end of the rotating member 110 away from its own rotation axis is positioned within the chassis 200 so that during the rotation of the rotating member 110 around the chassis 200, the end of the rotating member 110 away from its own rotation axis can abut against the panel 310.

[0042] The lever 120 is detachably connected to the rotating member 110. The lever 120 is used to move the rotating member 110 and is detachably connected to the panel 310. Specifically, when the rotating member 110 needs to be moved, the lever 120 can be connected to the rotating member 110 so that the moving operation of the rotating member 110 can be performed through the lever 120. When the panel 310 needs to be lifted, the connection between the lever 120 and the rotating member 110 can be released, and the lever 120 can be connected to the panel 310, such as by inserting the lever 120 into the lifting hole 311, and the lifting operation of the panel 310 can be performed through the lever 120. In the present application, the chassis 200 is provided with a storage slot 220, which can be used to store and accommodate the removed lever 120.

[0043] When the lever 120 moves the rotating member 110, the lever 120 drives the rotating member 110 to rotate relative to the chassis 200, and the rotating member 110 rotates to abut against the panel 310 and pushes the panel 310 away from the chassis 200; when the lever 120 is connected to the panel 310, the panel 310 can be lifted. Specifically, when it is necessary to remove the board 300 on the chassis 200, first, the lever 120 is connected to the rotating member 110; then, the lever 120 is moved to rotate the rotating member 110 relative to the chassis 200, and the rotating member 110 rotates to abut against the panel 310, and the rotating member 110 applies a force to the panel 310 and pushes the panel 310 away from the chassis 200, so that the panel 310 moves toward the side of the card slot 210 to a preset height (for example, the preset height is Figure 1As shown in H1 , the board 300 is pre-removed. Next, the lever 120 is disconnected from the rotating member 110 and connected to the panel 310, for example, by inserting the lever 120 into the lifting hole 311 of the panel 310. Finally, the panel 310 is lifted using the lever 120 to remove the board 300 from the chassis 200. The aforementioned card-assisted removal mechanism 100, through the lever 120, increases the operating space for the board 300 during removal, facilitating removal of the board 300 without damaging it.

[0044] In one embodiment, see Figures 1-3 As shown, the board card extraction mechanism 100 also includes a fixing member 130, which is set on the chassis 200 by screwing, welding, etc., and the rotating member 110 is rotatably set on the fixing member 130, so that the rotating member 110 is indirectly fixed to the chassis 200 through the fixing member 130, and the rotating member 110 can be rotated relative to the chassis 200. During the rotation process, the rotating member 110 can abut against the side of the panel 310 facing the card slot 210 to perform a pre-disassembly operation on the board card 300.

[0045] Further, see Figures 1-3 As shown, the rotating member 110 includes a connecting portion 111, a rotating portion 112, and an abutting portion 113. The rotating portion 112 is rotatably mounted on the fixed member 130. The rotating portion 112 enables the rotating member 110 to rotate relative to the fixed member 130. The two sides of the rotating portion 112 are respectively connected to the connecting portion 111 and the abutting portion 113. The lever 120 is detachably connected to the connecting portion 111. During the rotation of the rotating portion 112 relative to the fixed member 130, the abutting portion 113 can abut against the side of the panel 310 facing the slot 210. Specifically, when the board 300 needs to be pre-removed, the lever 120 can be connected to the connecting portion 111, and the lever 120 can be moved to rotate the rotating portion 112 relative to the fixing member 130. When the abutting portion 113 abuts the side of the panel 310 facing the slot 210, the abutting portion 113 applies a force to the panel 310. Through the principle of leverage, the panel 310 can be moved to a predetermined height in a direction away from the slot 210, thereby pre-removing the board 300 and reducing the force required by the board-and-card extraction mechanism 100 to pre-remove the board 300. Preferably, the connecting portion 111, the rotating portion 112, and the abutting portion 113 can be integrally formed by injection molding, extrusion, or the like to simplify the molding process of the rotating member 110 and improve the structural strength of the rotating member 110.

[0046] In order to realize the connection between the lever 120 and the rotating member 110, in one embodiment, refer to Figures 1-3As shown, the connecting portion 111 defines a plug-in slot 1111, into which the lever 120 can be inserted. For example, the lever 120 can be inserted into the plug-in slot 1111 by a clearance fit, thereby achieving a detachable connection between the lever 120 and the rotating member 110, and the lever 120 can perform a toggling operation on the rotating member 110. Preferably, the connecting portion 111 of the rotating member 110 is integrally formed with the plug-in slot 1111 by injection molding, extrusion, or the like, to simplify the molding process for forming the plug-in slot 1111 on the rotating member 110.

[0047] In order to realize the rotation connection of the rotating member 110 on the fixed member 130, in one embodiment, refer to Figures 1-3 As shown, the fixed member 130 defines a mounting slot 131, and the rotating member 110 is rotatably mounted in the mounting slot 131. That is, the mounting slot 131 can accommodate the rotating member 110. For example, the rotating portion 112 of the rotating member 110 is rotatably mounted in the mounting slot 131. When the lever 120 is actuated to rotate the rotating portion 112 relative to the fixed member 130, the abutting portion 113 can exert a force on the panel 310, causing the panel 310 to move toward the side away from the card slot 210, thereby achieving a pre-disassembly operation for the board 300. There is resistance between the rotating member 110 and the fixed member 130. Only when the lever 120 is moved, so that the force exerted by the lever 120 on the rotating member 110 is greater than the resistance between the rotating member 110 and the fixed member 130, can the rotating member 110 rotate relative to the fixed member 130. When the lever 120 abuts the panel 310, the panel 310 moves in a direction away from the slot 210. After the connection between the lever 120 and the rotating member 110 is released, due to the resistance between the rotating member 110 and the fixed member 130, the rotating member 110 can maintain the board 300 at a predetermined height away from the slot 210. Preferably, the fixed member 130 is integrally formed with the mounting groove 131 by injection molding, extrusion, or the like, to simplify the molding process of forming the mounting groove 131 on the fixed member 130.

[0048] In order to ensure the smooth rotation of the rotating member 110, refer to Figures 1-3 As shown, the chassis 200 is provided with an escape groove 230, and the rotating member 110 is at least partially accommodated in the escape groove 230. That is, the rotating member 110 is disposed in the chassis 200 and can be completely accommodated in the escape groove 230, or the rotating member 110 can be partially accommodated in the escape groove 230. When the lever 120 is toggled, the lever 120 drives the rotating member 110 to rotate. The escape groove 230 allows for the rotation of the rotating member 110, thereby preventing the chassis 200 from interfering with the rotation of the rotating member 110. Preferably, the escape groove 230 is integrally formed in the chassis 200 by injection molding, extrusion, or other methods to simplify the molding process of forming the escape groove 230 in the chassis 200.

[0049] In one embodiment, participation Figures 1-3 As shown, the lever 120 can be inserted into the lifting hole 311, and when the lever 120 is inserted into the lifting hole 311, the panel 310 can be lifted. In other words, in this embodiment, the lever 120 can be used to lift and remove the board 300 through the cooperation between the lever 120 and the lifting hole 311.

[0050] Specifically, see Figures 1-3 As shown, the lever 120 includes a toggle portion 121 and a plug portion 122, which are connected to each other. Preferably, the toggle portion 121 and the plug portion 122 are integrally formed by injection molding, extrusion, or other methods to simplify the molding process of the lever 120 and improve the structural strength of the lever 120. The plug portion 122 is provided with a protrusion 1221, which protrudes from the circumferential surface of the plug portion 122. When the plug portion 122 is inserted into the lifting hole 311, the protrusion 1221 can pass through the lifting hole 311 and move to the side of the panel 310 away from the toggle portion 121. When the lever 120 is rotated, the protrusion 1221 can engage with the side of the panel 310 facing the slot 210. That is, when the board 300 needs to be pulled, the protrusion 1221 can pass through the pulling hole 311 and move to the side of the panel 310 away from the toggle portion 121, so that the plug-in portion 122 of the toggle lever 120 can be smoothly inserted into the pulling hole 311, and the toggle lever 120 is rotated to participate in the pulling operation. Figure 4 As shown, the protrusion 1221 can be engaged with the side of the panel 310 facing the card slot 210, and the protrusion 1221 can interfere with the movement of the lever 120 in the lifting hole 311, so that there is a connection relationship between the lever 120 and the panel 310, thereby realizing the lifting operation of the board 300 by the lever 120, and the lever 120 can remove and pull out the board 300.

[0051] Further, see Figures 1-3As shown, the outer diameter of the insertion part 122 at the protrusion 1221 is smaller than the aperture diameter of the lifting hole 311 in the first radial direction. When the insertion part 122 is inserted towards the lifting hole 311, the protrusion 1221 is accommodated in the first radial direction of the lifting hole 311, avoiding interference from the lifting hole 311 on the insertion operation of the lever 120, so that the lever 120 can be smoothly inserted into the lifting hole 311. And the outer diameter of the insertion part 122 at the protrusion 1221 is smaller than the aperture diameter of the lifting hole 311 in the second radial direction. When the protrusion 1221 moves through the lifting hole 311 to the side of the panel 310 facing the card slot 210 and the lever 120 is rotated, the protrusion 1221 can be clamped in the second radial direction of the lifting hole 311, and the protrusion 1221 interferes with the movement of the lever 120 in the lifting hole 311, so that a connection relationship is formed between the lever 120 and the panel 310, realizing the lifting operation of the lever 120 on the board card 300, and the lever 120 can perform disassembly and extraction operations on the board card 300. Among them, the lifting hole 311 can be one of an oval hole, a rectangular hole or a slotted hole. The specific type of the lifting hole 311 is not limited in this application.

[0052] Of course, in other feasible embodiments, the protrusion 1221 can also be elastically arranged on the surface of the insertion part 122. When the insertion part 122 needs to be inserted into the lifting hole 311, the inner wall of the lifting hole 311 forming the lifting hole 311 will apply a force to the protrusion 1221, and the protrusion 1221 moves towards the inside of the insertion part 122 to ensure that the insertion part 122 can be smoothly inserted into the lifting hole 311 through the lifting hole 311. And when the protrusion 1221 moves through the lifting hole 311 to the side of the panel 310 facing the card slot 210, the force applied to the surface of the protrusion 1221 disappears, and the protrusion 1221 resets under the elastic action. The protrusion 1221 interferes with the movement of the lever 120 in the lifting hole 311, so that a connection relationship is formed between the lever 120 and the panel 310, realizing the lifting operation of the lever 120 on the board card 300, and the lever 120 can perform disassembly and extraction operations on the board card 300.

[0053] In addition, this application also provides a testing machine 400. The testing machine 400 includes a chassis 200, at least one board card 300 and a board card extraction assisting mechanism 100 as described in the above technical solution. The chassis 200 has a card slot 210. The board card 300 includes a panel 310 and a functional board 320. The panel 310 is provided with a lifting hole 311. The board card 300 is vertically inserted into the card slot 210 so that the functional board 320 is located inside the chassis 200, and the panel 310 overlaps the opening end of the card slot 210, and the installation and fixation of the board card 300 on the chassis 200 are realized through the panel 310. In this application, the functional board 320 has a connector 330. When the board card 300 is vertically inserted into the card slot 210 and the connector 330 is connected to the backplane of the chassis 200, testing operations can be performed through the board card 300.

[0054] For the above-mentioned testing machine 400, when it is necessary to perform the operation of removing and inserting the circuit board 300 on the chassis 200, first, connect the lever 120 to the rotating member 110; then, toggle the lever 120 to make the rotating member 110 rotate relative to the chassis 200. The rotation of the rotating member 110 can abut against the panel 310, and the rotating member 110 applies a force to the panel 310 and pushes the panel 310 to move away from the chassis 200, so that the panel 310 moves to a preset height in the direction towards the side away from the card slot 210, and a pre-removing and inserting operation is performed on the circuit board 300; then, disconnect the connection between the lever 120 and the rotating member 110, and connect the lever 120 to the panel 310; finally, lift the panel 310 through the lever 120, and the operation of removing and inserting the circuit board 300 on the chassis 200 can be realized. The testing machine 400 provided by the present application can increase the operation space of the circuit board 300 during the removal and insertion process through the circuit board assisting extraction mechanism 100, which is convenient for the removal and insertion operation of the circuit board 300, and will not damage the circuit board 300 during the removal and insertion process.

[0055] Further, referring to Figures 1-3 As shown, there are multiple circuit board assisting extraction mechanisms 100, and the circuit board assisting extraction mechanisms 100 are arranged on both sides opposite to the card slot 210. In this way, when it is necessary to perform the operation of removing and inserting the circuit board 300 on the chassis 200, the circuit board 300 can be removed and inserted through the circuit board assisting extraction mechanisms 100 on both sides of the card slot 210. On the one hand, through the two circuit board assisting extraction mechanisms 100, the acting force of the circuit board 300 during the removal and insertion process can be increased, which is beneficial to the removal and insertion operation of the circuit board 300 on the chassis 200. On the other hand, the two circuit board assisting extraction mechanisms 100 can improve the stability of the circuit board assisting extraction mechanism 100 during the removal and insertion process by performing the removal and insertion operation on the circuit board 300, and further avoid damaging the circuit board 300 during the removal and insertion process.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-mentioned embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be understood as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
