[0040] In existing testing equipment, the display screen is mostly fixed by an external bracket, which can lead to instability during operation. Furthermore, because the display screen is externally mounted, the connecting cables are exposed, affecting the cleanliness of the testing equipment's surface. During transportation, the display screen and external bracket need to be disassembled, and reinstallation is required for use, making the process cumbersome.

[0041] To solve the above-mentioned technical problems, this utility model proposes a folding mechanism 100.

[0042] Reference Figure 1 and Figure 2 In one embodiment of this utility model, the folding mechanism 100 is used for a testing device 200. The testing device 200 includes an outer cover folding mechanism 100, a mounting plate 10, a tray 20, and at least one set of hinge components 50. The mounting plate 10 is provided with a display area 11 and a storage area 13 spaced apart. The display area 11 is used to mount a display screen 60. The tray 20 is foldably disposed at the bottom of the mounting plate 10 and is used to place a keyboard 70. The tray 20 has a stored state that fits against the storage area 13 and an unfolded state that is open relative to the mounting plate 10. The hinge components 50 connect the mounting plate 10 and the outer cover respectively. The mounting plate 10 has a first state that is stored in the outer cover and a second state that is unfolded relative to the outer cover through the hinge components 50.

[0043] The mounting plate 10 can be made of metal or high-strength plastic. The thickness of the mounting plate 10 is greater than the thickness of the display screen 60. The display area 11 is used to mount the display screen 60. The mounting plate 10 can have a mounting groove (not shown in the figure) in the display area 11. The display screen 60 can be installed inside the mounting groove. The inner wall of the mounting groove can also have mounting clips to further secure the display screen 60. Furthermore, a protective cover can be provided in the display area 11 to protect the display screen 60 mounted thereon. To facilitate heat dissipation from the display screen 60, multiple heat dissipation holes are provided on the bottom wall of the mounting groove. These holes dissipate the heat generated during the operation of the display screen 60. Understandably, the area of ​​the heat dissipation holes can avoid the area where the first base 51 contacts the mounting plate 10 to improve the strength of the mounting plate 10. The storage area 13 can be designed as a recess or a structure with a barrier. The storage area 13 is used to place accessories such as the keyboard 70 and mouse 80. The tray 20 can be connected to the mounting plate 10 via a hinge structure. The unfolding angle of the tray 20 can be set between 90 degrees and 180 degrees. The hinge assembly 50 can adopt a rotating hinge, damping hinge, or other structure to achieve smooth unfolding and folding.

[0044] In this invention, the display screen 60 and keyboard 70 are mounted and stored using a mounting plate 10. The mounting plate 10 is reliably connected to the testing device 200 via a hinge assembly 50, avoiding the hassle of disassembly and assembly during transportation. Furthermore, the folding design of the tray 20 facilitates the placement and operation of the keyboard 70, and allows it to be fitted into the storage area 13 when not in use, saving space while maintaining ease of use. The folding mechanism 100 ensures the surface of the testing device 200 remains clean during storage and allows for quick unfolding during use, improving work efficiency.

[0045] Reference Figure 1 and Figure 2In one embodiment of the present invention, one side of the outer cover is recessed with a receiving groove 210, and the mounting plate 10 is housed in the receiving groove 210 in the first state.

[0046] In one embodiment of the present invention, the receiving groove 210 can be located on either the left or right side of the outer cover. The depth of the receiving groove 210 can match the thickness of the mounting plate 10, ensuring a flat overall appearance when stored. By providing the receiving groove 210, the mounting plate 10 is housed within the receiving groove 210 when stored, preventing bumps and knocks to the display screen 60 and further enhancing the safety of the display screen 60 when stored.

[0047] Reference Figures 2 to 5 In one embodiment of the present invention, the hinge assembly 50 includes a first seat 51, a second seat 53 and a rotating shaft 54. The first seat 51 includes a fixing part 511 and a connecting part 513 that are connected and arranged at an angle. The fixing part 511 is fixed to the mounting plate 10. The second seat 53 is fixed to the outer cover and is rotatably connected to the connecting part 513 through the rotating shaft 54.

[0048] In one embodiment of the present invention, the fixing part 511 of the first base 51 can be fixedly connected to the mounting plate 10 by threaded connection or welding. Both the fixing part 511 and the connecting part 513 are generally block-shaped structures, and are an integral structure. The extension length of the fixing part 511 is relatively long, which can be half the length of the mounting plate 10, or slightly shorter than the length of the mounting plate 10. This allows for sufficient contact area between the fixing part 511 and the mounting plate 10, thereby improving the reliability of the connection between them. The included angle between the connecting part 513 and the fixing part 511 can be 90 degrees, i.e., a right angle is formed between them. This angle design ensures that the mounting plate 10 maintains a better viewing angle in the unfolded state. The rotating shaft 54 ​​can be made of stainless steel. It can be fixed to either the second seat 53 or the first seat 51, and rotatably connected to the other. The second seat 53 can be connected to the outer cover using countersunk screws. When the outer cover has a receiving groove 210, the second seat 53 can be fixed in the pre-machined threaded hole on the side wall of the receiving groove 210 using countersunk screws. During installation, the reliability of the connection between the screws and the second seat 53 must be ensured. By using the rotating shaft 54 ​​to achieve a rotatable connection between the first seat 51 and the second seat 53, the mounting plate 10 can be rotatably connected, facilitating its storage when not in use.

[0049] Reference Figures 2 to 5In one embodiment of the present invention, the hinge assembly 50 further includes at least one first damping structure 55. The first damping structure 55 includes a first damping member 551 and a second damping member 552 that are rotatably connected. The first damping member 551 is fixed to the connecting part 513, and the second damping member 552 is fixed to the outer cover.

[0050] In one embodiment of the present invention, the first damping structure 55 can be implemented in various ways. For example, the first damping element 551 and the second damping element 552 can be a mating friction plate structure, and the damping effect is achieved by adjusting the pressure between the friction plates. Alternatively, the first damping element 551 and the second damping element 552 can be a liquid buffer structure, generating damping through the flow resistance of the liquid. The first damping element 551 and the second damping element 552 can be a rotary damper, wherein the first damping element 551 is a fixed end and the second damping element 552 is a rotating end, and the damping torque is generated by the combined action of the internal elastic element and friction element. The first damping element 551 can be fixed to the connecting part 513 by bolts, and the second damping element 552 is fixed to the outer cover by welding or bolts; when the outer cover is provided with a receiving groove 210, the second damping element 552 is fixed to the side wall of the receiving groove 210 by welding or bolts. By adding a damping structure to the hinge assembly 50, the swaying problem that may occur in the folding mechanism 100 during unfolding and folding is effectively improved. When the mounting plate 10 rotates relative to the receiving groove 210, the damping torque generated between the first damping member 551 and the second damping member 552 can smoothly control the rotation speed, avoid impact caused by sudden movement, improve the stability of the folding mechanism 100, and also enable the display screen 60 to maintain smooth movement during unfolding and folding, avoid component wear caused by rapid movement, and improve the operating feel.

[0051] Reference Figures 2 to 5 In one embodiment of the present invention, the surface of the connecting part 513 is provided with a fixing groove 5131, and the first damping member 551 is disposed in the fixing groove 5131.

[0052] In one embodiment of the present invention, the fixing groove 5131 is a groove structure provided on the surface of the connecting portion 513, used to accommodate and fix the first damping member 551. The shape of the fixing groove 5131 can be rectangular, circular, or other geometric shapes, and its shape matches the shape of the first damping member 551, improving the reliability of fixing the first damping member 551. The fixing groove 5131 can be provided with positioning holes so that the first damping member 551 can be further fixed by the cooperation of screws with the positioning holes. The depth of the fixing groove 5131 is slightly greater than the thickness of the first damping member 551, so that the first damping member 551 is flush with the surface of the connecting portion 513 after installation. By providing the fixing groove 5131 in the connecting portion 513, the precise positioning and stable installation of the first damping member 551 are achieved, and at the same time, it can prevent the first damping member 551 from shifting or falling off when the hinge assembly 50 moves, thereby ensuring the stable operation of the damping structure.

[0053] Reference Figures 2 to 5 In one embodiment of the present invention, a first damping structure 55 is provided on the top and bottom surfaces of the first base 51, respectively.

[0054] In one embodiment of the present invention, by providing a first damping structure 55 at both the upper and lower symmetrical positions of the hinge assembly 50, the unilateral deflection torque during the folding process of the display screen 60 can be effectively eliminated, and the display screen 60 can be prevented from shaking when unfolding or storing. At the same time, the first damping structure 55 is located on the top and bottom surfaces of the hinge assembly 50, which also improves the stability of the folding mechanism 100, especially during equipment transportation, it can better protect the display screen 60 from vibration damage.

[0055] Reference Figures 2 to 5 In one embodiment of this utility model, a second damping structure 23 is provided between the tray 20 and the mounting plate.

[0056] In one embodiment of the present invention, the second damping structure 23 is used to control the switching speed of the tray 20 between the retracted and unfolded states, avoiding mechanical impact or component wear caused by rapid opening and closing. The second damping structure 23 can be a mating friction plate structure or a rotary damper. The rotary damper is coaxially mounted with a hinge via a bushing, its inner ring is fixedly connected to the mounting plate, and its outer ring is linked to the rotating components of the tray 20, thereby generating resistance when the tray 20 rotates. It is understood that any structure that can achieve damping and limiting during the rotation of the tray 20 relative to the mounting plate 10 is acceptable; therefore, the second damping structure 23 will not be described in detail here.

[0057] Reference Figures 2 to 5In one embodiment of the present invention, a mouse storage slot 131 is provided in the storage area 13 of the mounting plate 10, which is used to store a mouse 80.

[0058] In one embodiment of this utility model, the mouse storage slot 131 can be a groove formed by recessing the surface of the storage area 13 or a detachable storage rack. As one feasible implementation, the size of the groove matches the shape of a common mouse 80, and an anti-slip pad or limiting structure is provided within the groove to prevent the mouse 80 from sliding. The mouse storage slot 131 is positioned adjacent to the storage area 13 of the tray 20, facilitating quick access to the mouse 80 when unfolded. By integrating the mouse storage slot 131 into the storage area 13, the input devices of the detection device 200, namely the keyboard 70 and the mouse 80, can be simultaneously stored or unfolded with the display screen 60, avoiding the problem of separate storage of the external mouse 80. This design not only simplifies the disassembly and assembly process during device transportation but also maintains the cleanliness of the work surface.

[0059] Reference Figures 2 to 5 In one embodiment of this utility model, a first magnetic suction member 133 is provided on the top of the storage area 13, and the tray 20 is made of magnetic material. When the tray 20 is in the storage state, the first magnetic suction member 133 and the tray 20 are fixed by magnetic attraction.

[0060] In one embodiment of the present invention, the first magnetic chuck 133 can be a permanent magnet or an electromagnet, and its installation method includes embedded fixing or surface attachment; the tray 20 is made of magnetic material, meaning that the entire tray can be made of iron or iron alloy, or the area of ​​the tray 20 in contact with the first magnetic chuck 133 is made of magnetic material. Magnetic material includes both ferromagnetic materials and magnets with polarity opposite to the first magnetic chuck material. As one feasible implementation, the first magnetic chuck 133 is a magnet block, fixed to the metal substrate at the top of the storage area 13 by countersunk screws; the entire tray 20 is made of iron or iron alloy. Furthermore, there are multiple first magnetic chucks 133, which are arranged at intervals to enhance adsorption stability. The magnetic structure achieves automatic positioning and fixing of the tray 20 in the storage state, solving the positioning deviation and wear problems of traditional mechanical buckles. When the tray 20 is folded into the storage area 13, the magnetic attraction allows the tray 20 to quickly and accurately align with the storage position, preventing accidental unfolding due to vibration. The magnetic connection eliminates the need for physical locking, reducing wear on the tray 20 and extending its service life.

[0061] In one feasible embodiment, the entire tray 20 itself can be made of magnetic material to reduce the number of parts and assembly problems caused by additional magnetic material on the tray 20.

[0062] In another possible embodiment, the tray 20 itself can be made of plastic, and the part of the tray 20 that contacts the first magnetic member 133 can be made of magnetic material. That is, during the molding process of the plastic tray 20, the magnetic material can be set inside the tray 20 by inserts. Alternatively, magnetic material can be attached to the tray 20. Specifically, the magnetic material can also be a nickel-plated soft magnetic alloy sheet, which is fixed to the contact surface of the tray 20 by adhesive.

[0063] Reference Figures 2 to 5 In one embodiment of this utility model, the mounting plate 10 is provided with a wire passage hole 15, which is located between the display area 11 and the storage area 13. The folding mechanism 100 also includes a wire guide 30, a pressure block, and a cover 35. The wire guide 30 is located on the side of the mounting plate 10 where the hinge assembly 50 is located. The wire guide 30 is positioned close to the wire passage hole 15. A wire receiving groove 31 is formed inside the wire guide 30. The pressure block is located in the wire receiving groove 31 and is used to press the cable received in the wire receiving groove 31. The cover 35 is connected to the wire guide 30 and covers the wire receiving groove 31.

[0064] In one embodiment of this utility model, the cable guide hole 15 is used for the connection cable of the display screen 60 and the keyboard 70 to pass through. The cable guide 30 is used to fix and protect the connection cable, preventing it from being exposed. The pressure block is used to press the connection cable tightly into the cable receiving groove 31 to prevent it from loosening. The cover 35 is used to close the cable receiving groove 31, further protecting the connection cable and serving as a decorative element to enhance the aesthetics. The connection cable of the display screen 60 passes through the cable guide hole 15, and is then pressed and fixed in the cable guide 30 by the pressure block before exiting from the other end. The cover 35 serves a decorative function. The cable guide 30 is fixed to the mounting plate 10 and can rotate with the mounting plate 10. By setting the cable guide hole 15, the cable guide 30, the pressure block, and the cover 35, the orderly arrangement and protection of the connection cable are achieved, avoiding the problem of exposed connection cables and affecting the cleanliness of the equipment surface.

[0065] Reference Figures 2 to 5 In one embodiment of this utility model, two hinge components 50 are arranged at intervals in the vertical direction of the mounting plate 10, and a cable guide 30 is located between the two hinge components 50. The cable guide 30 is located near the cable passage hole 15, and a cable receiving groove 31 is formed inside. The cable receiving groove 31 is provided with a pressure block for clamping the cable, and the top of the cable receiving groove 31 is closed by a cover 35. The cable passage hole 15 is located between the display area 11 and the storage area 13.

[0066] In one embodiment of the present invention, the spacing between the two hinge components 50 enhances the stability of the mounting plate 10 during unfolding and retraction. The design of the cable guide 30 allows the cable to pass directly into the cable tray 31 after exiting the cable through the cable hole 15, preventing cable exposure. By providing two hinge components 50, the stability of the mounting plate 10 is further improved, and the reasonable layout of the cable guide 30 facilitates cable management, enhancing the overall appearance of the testing equipment 200.

[0067] In one feasible embodiment, the mounting plate 10 is further provided with a first latch (not shown in the figure) on the side away from the hinge assembly 50, so that the user can pull the mounting plate 10 out of the receiving groove 210 through the first latch.

[0068] In one feasible embodiment, the tray 20 is further provided with a second handle position 22 on the side away from the bottom of the mounting plate 10, so that the user can unfold the tray 20 from the storage area 13 through the second handle position 22.

[0069] The above description is only an achievable embodiment of the present utility model and does not limit the patent scope of the present utility model.
