[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0060] The torque detection device provided in this embodiment of the utility model is applied to the hinge 2 of a folding device and includes: a clamping assembly, a rotating assembly and a detection assembly;

[0061] like Figure 1 As shown, the clamp assembly includes: a fixed clamp 11 and a movable clamp 12;

[0062] Fixture 11 is used to fix the first torsion arm 21 of hinge 2;

[0063] The movable clamp 12 is located at the movable end of the rotating assembly and is used to clamp the second torsion arm 22 of the hinge 2;

[0064] The rotating component drives the second torsion arm 22 of the hinge 2 to rotate through the movable clamp 12, so that the hinge 2 switches back and forth between the open state and the closed state.

[0065] When hinge 2 switches back and forth between the open and closed states, the detection component is used to detect the torque of hinge 2.

[0066] It should be noted that foldable devices can refer to foldable screen electronic devices, such as foldable screen phones; for example... Figure 4As shown, hinge 2 has two pivots. The base 23 of hinge 2 is rotatably connected to the first torsion arm 21 via the first pivot, and the base 23 is rotatably connected to the second torsion arm 22 via the second pivot. Furthermore, the first torsion arm 21 of hinge 2 can be the right torsion arm, and the second torsion arm 22 can be the left torsion arm. Figure 1 As shown, the fixing clamp 11 is used to fix the first torsion arm 21 of the hinge 2, so that the first torsion arm 21 of the hinge 2 is fixed relative to the second torsion arm 22; the movable clamp 12 is disposed at the movable end of the rotating assembly and is used to clamp the second torsion arm 22 of the hinge 2; the rotating assembly drives the second torsion arm 22 of the hinge 2 to rotate relative to the first torsion arm 21 through the movable clamp 12, as shown. Figure 11 As shown, the hinge 2 can switch back and forth between the open and closed states. The rotating component can rotate the second torsion arm 22 by swinging, and its axis of rotation can be coaxial (in the same direction) with the axis of rotation of the second torsion arm 22 of the hinge 2. When the hinge 2 switches back and forth between the open and closed states, the detection component is used to detect the torque on the hinge 2, thereby realizing the detection of the torque of the hinge. That is, this torque detection device is suitable for the torque detection of the hinge, ensuring the quality of the hinge and reducing the risk of quality problems in the hinge.

[0067] In other words, in the torque detection device provided by this solution, the first torsion arm 21 of the hinge 2 is fixed by the fixed clamp 11, the second torsion arm 22 of the hinge 2 is clamped by the movable clamp 12, and the second torsion arm 22 of the hinge 2 is indirectly driven to rotate relative to the first torsion arm 21 by the rotating component, so that the hinge 2 switches back and forth between the open state and the closed state. During this process, the torque on the hinge 2 is detected by the detection component, thereby realizing the detection of the torque of the hinge, ensuring the quality of the hinge is qualified, and reducing the risk of quality problems of the hinge.

[0068] In this solution, the rotating components include: a swing arm assembly and a displacement compensation assembly;

[0069] The pivot of the swing arm assembly is in the same direction as the pivot of the second torsion arm 22 of the hinge 2;

[0070] The displacement compensation component is located between the movable end of the swing arm assembly and the movable clamp 12, and is used to compensate for the displacement of the movable end of the swing arm assembly, so that the movable end of the swing arm assembly can drive the second torsion arm 22 of the hinge 2 to rotate more smoothly through the movable clamp 12.

[0071] It should be noted that the pivot of the swing arm assembly and the pivot of the second torsion arm 22 of the hinge 2 can be coaxial, facilitating the rotation of the second torsion arm 22 of the hinge 2 via the movable clamp 12. Furthermore, due to the unique structure of the hinge 2 (its two pivots rotate synchronously), the rotation path of the second torsion arm 22 of the hinge 2 is not a fixed circular arc path, but an irregular curved path. To ensure the free rotation of the second torsion arm 22 of the hinge 2, a displacement compensation component needs to be added between the movable end of the swing arm assembly and the movable clamp 12 to ensure the free rotation of the second torsion arm 22 of the hinge 2. The normal rotation of hinge 2 is ensured to prevent the second torsion arm 22 of hinge 2 from rotating unevenly or even jamming, thus ensuring that the movable end of the swing arm assembly can drive the second torsion arm 22 of hinge 2 to rotate normally through the movable clamp 12. The displacement compensation component can be a multi-dimensional translation compensation component in a plane, as detailed below. In other words, the rotation component drives the second torsion arm 22 of hinge 2 to rotate back and forth by swinging, and a displacement compensation component is added to the back and forth rotation of the second torsion arm 22 of hinge 2 to ensure that the rotation component can smoothly drive the second torsion arm 22 of hinge 2 to rotate normally through the movable clamp 12.

[0072] Specifically, such as Figure 2 As shown, the swing arm assembly includes: a swing arm 13, a bracket, and a drive assembly;

[0073] The swing arm 13 is rotatably mounted on the bracket, and its axis of rotation is in the same direction as the axis of rotation of the second torsion arm 22 of the hinge 2;

[0074] The drive assembly is mounted on the bracket and is used to drive the swing arm 13 to rotate back and forth;

[0075] The displacement compensation component is located at the movable end of the swing arm 13;

[0076] The movable clamp 12 is set at the compensation end of the displacement compensation component.

[0077] It should be noted that, as Figure 13 As shown, the bracket can be a support plate 4; the swing arm 13 is rotatably mounted on the top of the support plate 4 in a vertical direction, which can be in the same direction as the rotation axis of the second torsion arm 22 of the hinge 2; the drive assembly can be located at the bottom or below the support plate 4, and its output end is connected to the bottom of the swing arm 13 for driving the swing arm 13 to rotate back and forth in a vertical direction; wherein, as Figure 2As shown, the drive assembly may include: a coupling 112, connecting rods 113, a servo motor 114, a fixed base plate 115, a flange 116, and a connecting seat; the fixed base plate 115 is disposed below the support plate 4 via multiple connecting rods 113; the servo motor 114 is disposed at the bottom of the fixed base plate 115, and its output shaft passes upward through the fixed base plate 115; the flange 116 is disposed at the top of the support plate 4; a bearing is sleeved inside the flange 116, and the connecting seat is sleeved on the bearing and passes through the bearing before connecting to the coupling 112; the swing arm 13 is disposed on the connecting seat. The top of the servo motor 114 is connected to the connecting seat via a coupling 112; the movable clamp 12 is located at the compensation end (i.e., the displacement end) of the displacement compensation component; that is, the swing arm assembly has a swing arm body (i.e., swing arm 13) and a swing arm drive component (i.e., drive component), and the displacement compensation component is located at the movable end of the swing arm body, and the movable clamp 12 is located at the displacement end of the displacement compensation component, so that with displacement compensation, the rotating component can better drive the second torsion arm 22 of the hinge 2 to rotate via the movable clamp 12.

[0078] Furthermore, such as Figure 5 As shown, swing arm 13 is an L-shaped swing arm;

[0079] The horizontal part of the L-shaped swing arm can be rotatably mounted on the bracket;

[0080] The drive assembly is used to drive the horizontal part of the L-shaped swing arm to rotate back and forth;

[0081] The displacement compensation component is located at the end of the vertical part of the L-shaped swing arm, and its compensation end can be translated in two directions; wherein, the two directions are on the same horizontal plane, one direction is parallel to the horizontal part of the L-shaped swing arm, and the other direction is perpendicular to the horizontal part of the L-shaped swing arm.

[0082] Among them, such as Figure 13 As shown, the horizontal part of the L-shaped swing arm can be located at the top of the connecting seat; of course, the swing arm 13 can also adopt other structural forms, such as a Z-shaped structure, which will not be elaborated here; the servo motor 114 drives the horizontal part of the L-shaped swing arm to rotate around the vertical direction through the coupling 112 and the connecting seat in sequence; as shown Figure 5 As shown, the displacement compensation component can be set at the top of the vertical part of the L-shaped swing arm, and its displacement end can be translated in two directions; wherein, the two directions are on the same horizontal plane, and one direction is parallel to the horizontal part of the L-shaped swing arm, and the other direction is perpendicular to the horizontal part of the L-shaped swing arm; as mentioned above, that is, the displacement compensation component can be a two-dimensional displacement compensation component in a horizontal plane, so as to provide X-direction displacement compensation and Y-direction displacement compensation for the movable clamp 12, thereby facilitating the normal rotation of the second torsion arm 22 of the hinge 2; in addition, the swing arm 13 and the displacement compensation component are designed in this way to ensure that the movable end of the swing arm 13 can drive the second torsion arm 22 of the hinge 2 to rotate normally through the movable clamp 12.

[0083] Furthermore, the displacement compensation component includes: a first translation component and a second translation component;

[0084] The first translation component is disposed at the end of the vertical part of the L-shaped swing arm; the second translation component is disposed at the movable end of the first translation component; the movable clamp 12 is disposed at the movable end of the second translation component;

[0085] The translation direction of the movable end of the first translation component is perpendicular to the horizontal part of the L-shaped swing arm, and the translation direction of the movable end of the second translation component is perpendicular to the translation direction of the movable end of the first translation component.

[0086] It should be noted that the first translation component can be set at the top of the vertical part of the L-shaped swing arm. The translation direction of the movable end of the first translation component is horizontal and perpendicular to the horizontal part of the L-shaped swing arm. The translation direction of the movable end of the second translation component is horizontal and perpendicular to the translation direction of the movable end of the first translation component, which is parallel to the horizontal part of the L-shaped swing arm. In other words, the displacement compensation component is a two-dimensional horizontal displacement compensation component. Moreover, one horizontal displacement direction of the two-dimensional horizontal displacement compensation component is parallel to the horizontal part of the L-shaped swing arm, which is also parallel to the radial direction of the swing arm 13. The other horizontal displacement direction is perpendicular to the horizontal part of the L-shaped swing arm. In this way, the movable clamp 12 can achieve two-dimensional displacement adjustment in the horizontal plane, which makes it easier to ensure that the rotating component drives the second torsion arm 22 of the hinge 2 to rotate normally through the movable clamp 12.

[0087] In this plan, such as Figure 5 As shown, the first translation component is a slider component, and the second translation component is a slider component;

[0088] The slider assembly is located at the end of the vertical part of the L-shaped swing arm, and its slider 14 can slide along a horizontal direction perpendicular to the horizontal part of the L-shaped swing arm;

[0089] The slide rod assembly is mounted on the slider 14, and its slide rod 15 can slide in a horizontal direction parallel to the horizontal part of the L-shaped swing arm;

[0090] The movable clamp 12 is located at the free end of the slide bar 15.

[0091] It should be noted that, as Figure 5As shown, the slider assembly includes a guide rail 110 and a slider 14; the slide rod assembly includes a slide block 111 and a slide rod 15; wherein, the guide rail 110 is horizontally disposed at the top of the vertical part of the L-shaped swing arm and perpendicular to the horizontal part of the L-shaped swing arm, the slider 14 is slidably disposed on the guide rail 110, and the slider 14 can slide in a horizontal direction perpendicular to the horizontal part of the L-shaped swing arm; the slide block 111 is disposed at the top of the slider 14, and the slide rod 15 is slidably disposed on the slide block 111 in a horizontal direction, wherein the horizontal sliding direction of the slide rod 15 is parallel to the horizontal part of the L-shaped swing arm, that is, the slide rod 15... It can slide in a horizontal direction parallel to the horizontal part of the L-shaped swing arm; of course, other first translation components and second translation components can also be used in this solution, such as roller slide rail components; in addition, the sliding of the slider 14 and the slide rod 15 is spontaneous, that is, it has a tendency to slide; the movable clamp 12 can be set at the end of the slide rod 15; that is, the first translation component and the second translation component are designed in this way to provide compensation for two orthogonal horizontal displacement degrees of freedom for the movable clamp 12, thereby better ensuring that the rotating component can drive the second torsion arm 22 of the hinge 2 to rotate normally through the movable clamp 12.

[0092] Specifically, such as Figure 3 As shown, the detection assembly includes: a support 16, a torque sensor 17, and a connector;

[0093] Torque sensor 17 is mounted on support 16;

[0094] The connector is connected between the fixed clamp 11 and the torque sensor 17.

[0095] Among them, such as Figure 10 and Figure 13 As shown, support 16 can be a Z-shaped support, and can be installed on the top of support plate 4, located on one side of swing arm 13; as Figure 3 As shown, the torque sensor 17 can be mounted on the top of the Z-shaped support; the connector is connected between the bottom of the fixing clamp 11 and the detection end of the torque sensor 17, so as to transmit the torque force on the hinge 2 during the opening and closing process to the torque sensor 17; of course, the torque sensor 17 will be subjected to force during the opening and closing process of the hinge 2, and the torque value of the hinge 2 can be detected in real time; that is to say, the detection component is designed in this way, with a simple structure and convenient detection; in addition, as Figure 3 As shown, the connector includes: a support leg 18 and a connecting seat 19; the connecting seat 19 is disposed on the detection end of the torque sensor 17; the support leg 18 is disposed on the connecting seat 19 and is connected to the bottom of the fixing clamp 11.

[0096] Furthermore, such as Figure 1As shown, the fixed clamp 11 and / or the movable clamp 12 are elastic clamps, used to elastically clamp the first torsion arm 21 or the second torsion arm 22 of the hinge 2. This makes the fixing of the first torsion arm 21 of the hinge 2 and the clamping of the second torsion arm 22 of the hinge 2 more convenient and stable. Of course, the fixed clamp 11 and / or the movable clamp 12 in this solution can also adopt other clamping methods, such as fixed clamping, which will not be described in detail here.

[0097] Furthermore, the elastic clamp includes: a clamp base, a clamping plate, and an elastic component;

[0098] The clamping plate is rotatably mounted on the clamping seat and has switchable clamping and loosening states;

[0099] The elastic component is disposed in the clamp and is used to provide elastic force to the clamping plate so that the clamping plate is in a clamped state.

[0100] The clamping plate is rotatably mounted on the clamping seat via a pivot. When the clamping plate is in the clamping state, it is in contact with the clamping seat, thus clamping the first torsion arm 21 or the second torsion arm 22 of the hinge 2. When the clamping plate is in the unclamping state, it disengages from the clamping seat, thus releasing the first torsion arm 21 or the second torsion arm 22 of the hinge 2. An elastic component can be disposed between the clamping seat and the clamping plate, and is used to provide clamping elastic force to the clamping plate, so that the clamping plate is in the clamping state, thereby achieving elastic clamping of the first torsion arm 21 or the second torsion arm 22 of the hinge 2. In addition, the clamping plate can be switched to the unclamping state by pressing it. Of course, the elastic clamp is also similar to a spring clip.

[0101] More specifically, a blind groove is provided on a portion of the first sidewall of the clamp;

[0102] The middle part of the clamping plate is rotatably disposed on the side of the clamping seat where the blind groove is opened. When the clamping plate is in the clamping state, the first part of the clamping plate is clamped with the other part of the first side wall of the clamping seat where the blind groove is not opened. When the clamping plate is in the loosening state, the first part of the clamping plate is disengaged from the other part of the first side wall of the clamping seat where the blind groove is not opened.

[0103] The elastic component is disposed in the blind groove of the clamp and connected between the second part of the clamp and the bottom of the blind groove, and provides elastic clamping force to the first part of the clamp.

[0104] It should be noted that, as Figure 8 and Figure 9 As shown, the fixing clamp 11 includes: a fixing clamp base 11.1, a fixing clamp plate 11.2, a fixing elastic component 11.3, and a fixing rotating shaft 11.6; wherein, as... Figure 9As shown, a portion of the first sidewall of the fixed clamp 11.1 has a fixed blind groove 11.4. The middle portion of the fixed clamp plate 11.2 is rotatably mounted on the corner edge of the first sidewall of the fixed clamp 11.1 and the fixed blind groove 11.4 via a fixed pivot 11.6. The middle portion of the fixed clamp plate 11.2 has a rotating sleeve, which is fitted onto the outside of the middle portion of the fixed pivot 11.6. When the fixed clamp plate 11.2 is in the clamped state, its first portion clamps the other portion of the first sidewall of the fixed clamp 11.1 without the fixed blind groove 11.4. When the clamp is released, its first portion disengages from the other portion of the first sidewall of the fixed clamp 11.1 without the fixed blind groove 11.4. Figure 8 As shown, the inner wall of the second part of the fixing clamp 11.2 is provided with multiple fixing protrusions 11.5. Of course, the bottom of the fixing blind groove 11.4 can also be provided with multiple fixing protrusions 11.5, which correspond one-to-one with the multiple fixing protrusions 11.5 on the inner wall of the second part of the fixing clamp 11.2. The fixing elastic component 11.3 can be a spring. The fixing elastic component 11.3 abuts between the second part of the fixing clamp 11.2 and the bottom of the fixing blind groove 11.4, and one end of it is sleeved on the multiple fixing protrusions 11.5 of the second part of the fixing clamp 11.2, and the other end is sleeved on the multiple fixing protrusions 11.5 at the bottom of the fixing blind groove 11.4, thereby providing elastic clamping force for the first part of the fixing clamp 11.2.

[0105] Similarly, such as Figure 6 and Figure 7As shown, the movable clamp 12 includes: a movable clamping seat 12.1, a movable clamping plate 12.2, a movable elastic component 12.3, and a movable blind groove 12.4; wherein, a portion of the first sidewall of the movable clamping seat 12.1 has a movable blind groove 12.4, and the middle portion of the movable clamping plate 12.2 is rotatably disposed at the corner edge of the first sidewall of the movable clamping seat 12.1 and the movable blind groove 12.4 via a movable pivot. The middle portion of the movable clamping plate 12.2 is provided with a rotating sleeve, which is fitted onto the outside of the middle portion of the movable pivot. When the movable clamping plate 12.2 is in the clamping state, its first portion clamps with the other portion of the first sidewall of the movable clamping seat 12.1 without the movable blind groove 12.4; when the clamping is released, its first portion disengages from the other portion of the first sidewall of the movable clamping seat 12.1 without the movable blind groove 12.4. Of course, the inner wall of the second part of the movable clamping plate 12.2 can be provided with multiple movable bosses, and the bottom of the movable blind groove 12.4 can also be provided with multiple movable bosses, which correspond one-to-one with the multiple movable bosses on the inner wall of the second part of the movable clamping plate 12.2; the movable elastic component 12.3 can be a spring, which abuts against the second part of the movable clamping plate 12.2 and the bottom of the movable blind groove 12.4, with one end of the spring fitted onto the multiple movable bosses of the second part of the movable clamping plate 12.2 and the other end fitted onto the multiple movable bosses at the bottom of the movable blind groove 12.4, thereby providing elastic clamping force for the first part of the movable clamping plate 12.2; that is to say, the elastic clamp is designed in this way, which makes it more convenient and reliable to clamp the first torsion arm 21 or the second torsion arm 22 of the hinge 2.

[0106] In addition, such as Figure 12 As shown, this solution can also install multiple torque detection devices 1 in the cabinet 3, and the hinges 2 can be manually raised and lowered. After pressing the start button, the corresponding rotating components begin to rotate reciprocally to open and close the hinges 2. The torque sensor 17 can monitor the torque value of the hinges in real time and display the torque curve simultaneously through an external display device to control the quality of the hinges. Of course, this torque detection device technology can be applied to fields such as 3C, energy, and automotive testing, and can even be extended to the torque testing of various precision parts. Of course, adopting the above solution can achieve the following effects:

[0107] 1. Improve production efficiency, enabling the inspection of more hinges per unit time and reducing labor intensity;

[0108] 2. This testing device is highly versatile; similar hinges of similar size can be used by simply modifying the fixture.

[0109] 3. Real-time display of torque curve allows for better control of product quality.

[0110] In addition, the hinge inspection process is as follows:

[0111] 1. Hinges are supplied at 180° angles;

[0112] 2. Manually clamp the first torsion arm of the hinge onto the fixing fixture;

[0113] 3. Manually move the movable clamp to the appropriate distance;

[0114] 4. Manually clamp the second torsion arm of the hinge onto the movable fixture;

[0115] 5. The second torsion arm of the hinge is driven to rotate back and forth by the rotating component;

[0116] 6. The torque force on the hinge during opening and closing is detected by the torque sensor 17.
