[0008] The linkage device in this embodiment of the invention can enhance the stability of the support and prevent the electronic equipment from tipping over.

[0009] In some embodiments, the drive component includes a first shaft and a second shaft, the second shaft being connected to the support member. During the transmission stroke, the first shaft, the second shaft, and the support member are connected and can rotate synchronously. During the idle stroke, the first shaft and the second shaft are separated to allow the first shaft to idle.

[0010] In some embodiments, a flipping member is included, the flipping member being connected to the first shaft, the flipping member being adapted to drive the first shaft to reciprocate, and in the support position, the support member and the flipping member are stopped and limited.

[0011] In some embodiments, in the retracted position, the extending direction of the support member is consistent with the extending direction of the second shaft, and in the supported position, the extending direction of the support member and the extending direction of the second shaft form an angle.

[0012] In some embodiments, a limiting component is included, which acts between the first shaft and the second shaft, and during the idle stroke, the limiting component cooperates with the second shaft to limit the rotation of the second shaft.

[0013] In some embodiments, the limiting component includes a stop member, in which the first shaft and the second shaft are rotatable relative to the stop member during the transmission stroke, and in the idle stroke, the first shaft is rotatable relative to the stop member, the stop member engaging with the second shaft to restrict the rotation of the second shaft.

During the transmission stroke, the first protrusion and the second protrusion are blocked. During the idle stroke, the first protrusion can pass over the second protrusion. The movable portion can elastically extend and retract so that the first protrusion can pass over the second protrusion.

[0028] In some embodiments, the active portion includes:

[0029] An elastic element is sleeved on the outer periphery of the first shaft, and the elastic element is anti-rotationally engaged with the first shaft.

[0030] An adjusting member is provided, wherein the elastic element is sandwiched between the adjusting member and the fixed portion, the adjusting member is positionably disposed on the first shaft, and the adjusting member is adapted to block one end of the elastic element and adjust the elastic force of the elastic element.

[0031] In some embodiments, the fixed portion is provided with a first stop portion, and the first shaft is provided with a second stop portion, wherein the first stop portion is adapted to engage with the second stop portion to limit the rotational stroke of the first shaft.

[0032] In some embodiments, the device includes a housing with a first contact surface and a support with a second contact surface. In both the retracted position and the supported position, the first contact surface is in contact with the second contact surface.

[0033] In some embodiments, the second shaft is connected to the support member via a universal joint. The universal joint includes a first joint and a second joint.

[0065] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0066] like Figures 1 to 12 As shown, the linkage device 100 of this embodiment of the invention includes a driving component and a support component 4.

[0067] The drive component has a transmission stroke and an idle stroke. The drive component can rotate, and during rotation, its rotational stroke can be divided into a transmission stroke and an idle stroke. It should be noted that the drive component can rotate reciprocally, that is, it can rotate in both forward and reverse directions. During forward rotation, the drive component's rotation can also be divided into a transmission stroke and an idle stroke.

[0068] The support member 4 is connected to the drive component via a transmission mechanism. When the drive component rotates within its transmission stroke, it can rotate synchronously with the support member 4. When the drive component rotates within its idle stroke, at least a portion of the drive component idles relative to the support member 4.

[0069] For example, the drive component can be divided into two component units, namely the first component unit and the second component unit. When the drive component rotates within its idle stroke, the first component unit can rotate independently relative to the support member 4 and the second component unit. When the drive component rotates within its transmission stroke, the first component unit, the second component unit, and the support member 4 can rotate synchronously.

[0070] It is understood that in some other embodiments, when the drive component rotates within its idle stroke, the transmission between the drive component and the support 4 can be disconnected, at which time the entire drive component can rotate relative to the support 4.

[0071] The support member 4 has a retracted position and a supported position that can be switched via a transmission stroke. That is, when the drive component rotates within the transmission stroke, the support member 4 can rotate with the drive component and can switch between the retracted position and the supported position. When the support member 4 is switched to the retracted position, it is suitable for storage, thus facilitating the storage and organization of the linkage device 100. When the support member 4 is switched to the supported position, it is suitable for blocking and limiting, for example, the support member 4 can block and limit the display screen of the electronic device, thereby preventing the electronic device from flipping over.

[0072] The linkage device 100 of this embodiment of the invention has the function of rotational connection of a common hinge on the one hand, and the linkage effect between the driving component and the support member 4 on the other hand. That is, while realizing the hinge rotation function, the support member 4 can be switched to the support position. At this time, the support member 4 can play a supporting role for some components (display screen, tablet), thereby avoiding the problem of electronic devices tipping backward and enhancing the stability of the support.

[0073] In some embodiments, the drive component includes a first shaft 2 and a second shaft 3. The second shaft 3 is connected to a support member 4. During the transmission stroke, the first shaft 2, the second shaft 3, and the support member 4 are connected and can rotate synchronously. During the idle stroke, the first shaft 2 and the second shaft 3 are separated to allow the first shaft 2 to idle.

[0074] like Figure 1 As shown, both the first axis 2 and the second axis 3 can extend in the left-right direction, and the first axis 2 and the second axis 3 can be arranged substantially parallel to each other. The first axis 2 can extend along... Figure 1 When the first shaft 2 rotates in the direction of M, its rotational stroke can be divided into two segments: the transmission stroke and the idle stroke. During the transmission stroke, the first shaft 2 and the second shaft 3 are connected and can rotate synchronously. At this time, the support member 4 also rotates synchronously with the second shaft 3. During the idle stroke, the first shaft 2 and the second shaft 3 are disconnected. At this time, the first shaft 2 can continue to rotate, while the second shaft 3 and the support member 4 remain stationary.

[0075] It should be noted that during the forward and reverse rotation of the first shaft 2, the rotational stroke of the first shaft 2 can be divided into the transmission stroke and the idle stroke.

[0076] In some embodiments, the linkage device 100 includes a flipping member 1, which is connected to the first shaft 2. The flipping member 1 is adapted to drive the first shaft 2 to reciprocate, and in the support position, the support member 4 and the flipping member 1 are stopped and limited.

[0077] like Figure 1As shown, the flipper 1 can be connected to the left end of the first shaft 2, and the flipper 1 can engage with the first shaft 2 to prevent rotation. In use, rotating the flipper 1 can drive the first shaft 2 to rotate in the forward direction along M, or drive the first shaft 2 to rotate in the opposite direction to M.

[0078] In use, the flipping component 1 can be connected to the display screen of an electronic device, or the flipping component 1 can be integrated with the display screen and regarded as part of the display screen. The support component 4 and the stop limit of the flipping component 1 play a restraining role, thereby ensuring the stability of the support.

[0079] In some embodiments, in the retracted position, the extending direction of the support member 4 is consistent with the extending direction of the second shaft 3, and in the supported position, the extending direction of the support member 4 forms an angle with the extending direction of the second shaft 3.

[0080] like Figure 1 As shown, the support member 4 is connected to the second shaft 3 and can rotate synchronously with the second shaft 3. The support member 4 can be connected to the right side of the second shaft 3. During rotation, the support member 4 has a retracted position and a supported position, as shown. Figure 1 As shown, in the retracted position, the extension direction of the support member 4 is the same as the extension direction of the second shaft 3, that is, the support member 4 also switches to a position that extends roughly in the left and right direction.

[0081] like Figure 14 As shown, in the support position, the support member 4 and the second shaft 3 form an angle, and the support member 4 and the flipping member 1 are in a stop-and-stop cooperation, that is, the support member 4 can be supported obliquely on the ground or tabletop, and the bottom edge of the flipping member 1 can overlap the support member 4, thereby avoiding the situation where the flipping member 1 is suspended in the air after flipping.

[0082] In use, the linkage device 100 of this invention allows the flipping component 1 to be connected to components such as the display screen of an electronic device. After the flipping component 1 flips, the support component 4 can be supported below the flipping component 1, thereby enhancing the stability of the support and preventing the electronic device from tipping over.

[0083] Secondly, during the transmission stroke, the flipping component 1 can be driven by the transmission of the first shaft 2 and the second shaft 3 to rotate the support component 4 to the support position. Then, the support component 4 can remain in the support position, while the flipping component 1 can continue to rotate during the idle stroke. This can meet the large-angle opening and closing needs of the flipping component 1, enrich the angle adjustment of the flipping component 1, and help improve the convenience of use.

[0084] In some embodiments, the linkage device 100 includes a limiting component 6, which acts between the first shaft 2 and the second shaft 3. During the idling stroke, the limiting component 6 cooperates with the second shaft 3 to restrict the rotation of the second shaft 3. Since the first shaft 2 and the second shaft 3 will be disengaged during the idling stroke, the second shaft 3 is not constrained by external forces. When the support member 4 is subjected to force, the second shaft 3 and the support member 4 can easily rotate in opposite directions, thus failing to provide a supporting effect.

[0085] The limiting component 6 can take over the second axis 3 when the second axis 3 loses the constraint of the first axis 2. This prevents the second axis 3 from rotating arbitrarily, allowing the support component 4 to provide support. On the other hand, it allows the first axis 2 to rotate independently relative to the second axis 3, thereby achieving the requirement of large-angle opening and closing.

[0086] In some embodiments, the limiting component includes a stop 61. During the transmission stroke, the first shaft 2 and the second shaft 3 are rotatable relative to the stop. During the idle stroke, the first shaft 2 is rotatable relative to the stop. The stop engages with the second shaft 3 to restrict the rotation of the second shaft 3. That is, the stop only acts as a stop during the idle stroke, so that the idle rotation of the first shaft 2 can constrain the rotation of the second shaft 3 and the support member 4, thus achieving a locking effect.

[0087] In some embodiments, such as Figure 8 As shown, the limiting component 6 may also include a first cam 62 and a second cam 63.

[0088] The first cam 62 is mounted on the first shaft 2 and can rotate synchronously with the first shaft 2. The outer peripheral wall of the first cam 62 includes a first peripheral wall 621 and a guide groove 622. The first cam 62 is mounted on the outer peripheral side of the first shaft 2 to prevent rotation. The first cam 62 can rotate synchronously with the first shaft 2. The first cam 62 is generally circular. Figure 8 As shown, the outer peripheral wall of the first cam 62 may include two parts: a first peripheral wall 621 and a guide groove 622, wherein the radial dimension of the first cam 62 at the first peripheral wall 621 is greater than the radial dimension at the guide groove 622.

[0089] The second cam 63 is adapted to the second shaft 3 and can rotate synchronously with the second shaft 3. The outer peripheral wall of the second cam 63 includes a second peripheral wall 631 and a groove 632. Figure 8 As shown, the second cam 63 can be anti-rotated and mounted on the outer periphery of the second shaft 3. The second cam 63 can rotate synchronously with the second shaft 3. The second cam 63 is also generally circular. The outer periphery of the second cam 63 can include two parts: the second periphery wall 631 and the slot 632. The radial dimension of the second cam 63 at the second periphery wall 631 is greater than the radial dimension at the slot 632.

[0090] During the transmission stroke, the stop 61 fits between the guide groove 622 and the second peripheral wall 631, and the stop 61 slides along the guide groove 622. Figure 8 As shown, when the first shaft 2 rotates within the transmission stroke, the stop 61 can remain stationary. As the second shaft 3 rotates, the second circumferential wall 631 of the second cam 63 can be tangent to the stop 61 and rotate relative to the stop 61. At the same time, a part of the stop 61 can fit into the guide groove 622. As the first shaft 2 rotates, the guide groove 622 rotates circumferentially, causing the stop 61 to move relative to the stop within the guide groove 622.

[0091] During the idle stroke, the stop 61 engages between the slot 632 and the first peripheral wall 621. For example... Figure 8 As shown, when the first shaft 2 rotates within its idle stroke, the slot 632 on the second cam 63 has rotated to the stop 61. Under the stopping action of the stop 61, the second cam 63 can be locked in place, thus restricting the rotation of the second shaft 3. At the same time, the stop 61 has slid out of the guide groove 622, and the first peripheral wall 621 of the first cam 62 is tangent to the stop 61 and can rotate circumferentially relative to the stop 61. Thus, on the one hand, the stop 61 can be limited within the slot 632, and on the other hand, the need for the first shaft 2 to continue rotating within its idle stroke is also met.

[0092] In some embodiments, the stop member 61 is slidable between the first cam 62 and the second cam 63. When switching from the idle stroke to the transmission stroke, the stop member 61 slides into the guide groove 622 by the push of the second peripheral wall 631. When switching from the transmission stroke to the idle stroke, the stop member 61 slides into the slot 632 by the push of the first peripheral wall 621.

[0093] like Figure 3 As shown, the limiting component 6 can be clamped between two fixing members 9. The fixing members 9 can be plate-shaped and are used to install and fix the linkage device 100. Both the first shaft 2 and the second shaft 3 can pass through the two fixing members 9 and rotate in cooperation with them. Figure 7 As shown, both fixing members 9 can be provided with sliding grooves 911. The two sliding grooves 911 extend in the same direction, and the two ends of the stop member 61 slide and fit in the corresponding sliding grooves 911 respectively.

[0094] The stop 61 can slide along the extending direction of the two slide grooves 911. Thus, when the first shaft 2 transitions from its idle stroke to its transmission stroke, the second peripheral wall 631 of the second cam 63 can push the stop 61, thereby pushing the stop 61 into the guide groove 622. When the first shaft 2 transitions from its transmission stroke to its idle stroke, the first peripheral wall 621 of the first cam 62 can push the stop 61, thereby pushing the stop 61 into the retaining groove 632. The sliding of the stop 61 fulfills both the positioning requirement of the second cam 63 and the transmission requirements of the first shaft 2 and the second shaft 3.

[0095] In some embodiments, the stop 61 is rotatable. During the transmission stroke, the stop 61 rolls between the guide groove 622 and the second peripheral wall 631; during the idle stroke, the stop 61 rolls between the slot 632 and the first peripheral wall 621. Figure 8 As shown, the stop 61 can be generally cylindrical. Therefore, when the first shaft 2 rotates, the stop 61 can rotate on its own, thereby reducing the friction between the stop 61 and the first shaft 2 and the second peripheral wall 631, making the rotation drive of the first shaft 2 smoother.

[0096] In some embodiments, such as Figure 3 As shown, the linkage device 100 includes a transmission assembly 7, which acts between the first shaft 2 and the second shaft 3. During the transmission stroke, the first shaft 2 is connected to the second shaft 3 via the transmission assembly 7, and the rotation directions of the first shaft 2 and the second shaft 3 are the same. During the idle stroke, the transmission assembly 7 disengages, allowing the first shaft 2 to idle. This satisfies the transmission requirements between the first shaft 2 and the second shaft 3. The consistency of the rotation directions of the first shaft 2 and the second shaft 3 also ensures that the rotation directions of the flipping member 1 and the support member 4 are the same, meeting practical application requirements.

[0097] In some embodiments, the transmission assembly 7 includes an incomplete gear 71, a first gear 72, and a second gear 73. The incomplete gear 71 is disposed on the first shaft 2, the first gear 72 is disposed on the second shaft 3, and the second gear 73 engages with the incomplete gear 71 and the first gear 72. During the transmission stroke, the incomplete gear 71 and the second gear 73 engage with each other. During the idle stroke, the incomplete gear 71 and the second gear 73 disengage.

[0098] like Figure 9 As shown, the transmission assembly 7 can be clamped between two fixed members 9. The incomplete gear 71 can be anti-rotated and fitted on the outer periphery of the first shaft 2, the first gear 72 can be anti-rotated and fitted on the outer periphery of the second shaft 3, and the second gear 73 can be rotatably assembled between the two fixed members 9. One side of the second gear 73 can mesh with the first gear 72, and the other side of the second gear 73 can mesh with the incomplete gear 71.

[0099] During the rotation of the incomplete gear 71, the incomplete gear 71 can mesh with the second gear 73 or disengage from the second gear 73, thereby fulfilling the requirements for both transmission and non-transmission of the first shaft 2.

[0100] In some embodiments, the second gear 73 includes a first segment 731 and a second segment 732 in the axial direction. The incomplete gear 71 meshes with the first segment 731 for transmission, and the first gear 72 meshes with the second segment 732 for transmission. Figure 10 As shown, the second gear 73 has a certain extension length in the axial direction (left and right direction). The first segment 731 can be the left half of the second gear 73, and the second segment 732 can be the right half of the second gear 73. The incomplete gear 71 can be located to the left of the first gear 72 and mesh with the first segment 731. The second gear 73 meshes with the second segment 732. Thus, the incomplete gear 71 and the first gear 72 can be arranged in a staggered manner in space. On the one hand, this can avoid interference between the incomplete gear 71 and the first gear 72. On the other hand, it can improve the utilization rate of space and help to realize the miniaturization of the linkage device 100.

[0101] In some embodiments, the linkage device 100 includes a damping component 8, which includes a fixed portion 81 and a movable portion 82. The movable portion 82 is disposed on the first shaft 2 and can rotate with the first shaft 2. The fixed portion 81 and the movable portion 82 are attached together to form damping so that the first shaft 2 can be held in the position after rotation.

[0102] like Figure 2 and Figure 3 As shown, both the fixed part 81 and the movable part 82 can be fitted onto the outer periphery of the first shaft 2. The fixed part 81 can rotate with the first shaft 2, and the movable part 82 can stop the rotation of the first shaft 2. The fixed part 81 can be located to the left of the movable part 82. When the first shaft 2 rotates, the fixed part 81 can remain stationary, while the movable part 82 can rotate with the first shaft 2. Due to the damping effect formed between the fixed part 81 and the movable part 82, the first shaft 2 can remain in that position at any angle when rotating, thereby achieving the suspension of the flange at any position, allowing the user to switch to any angle as needed, which is convenient for use.

[0103] In some embodiments, the end face of the fixed portion 81 that is in contact with the fixed portion 81 is provided with a first protrusion 8111, and the end face of the movable portion 82 that is in contact with the fixed portion 81 is provided with a second protrusion 8211. During the transmission stroke, the first protrusion 8111 and the second protrusion 8211 are blocked. During the idle stroke, the first protrusion 8111 can pass over the second protrusion 8211. The movable portion 82 can elastically extend and retract so that the first protrusion 8111 can pass over the second protrusion 8211.

[0104] like Figure 5 As shown, the first protrusion 8111 can be located at the right end of the fixed portion 81. Multiple first protrusions 8111 can be provided, and these multiple first protrusions 8111 can be arranged at intervals along the circumference of the fixed portion 81. For example... Figure 6 As shown, the second protrusion 8211 can be provided at the left end of the movable part 82, and multiple second protrusions 8211 can be provided. Multiple second protrusions 8211 can be arranged at intervals along the circumference of the movable part 82.

[0105] In use, multiple first protrusions 8111 and multiple second protrusions 8211 can be arranged alternately in the circumferential direction. This can enhance the damping effect of the fixed part 81 and the movable part 82. On the other hand, when the first shaft 2 rotates to a set angle, the first protrusion 8111 can pass over the adjacent second protrusion 8211, thereby providing feedback to the user and improving the operating experience.

[0106] Optionally, both the first protrusion 8111 and the second protrusion 8211 can guide the inclined plane, thereby facilitating the first protrusion 8111 and the second protrusion 8211 to cross each other.

[0107] It should be noted that the movable part 82 can be elastically extended and retracted. Thus, on the one hand, the movable part 82 can be contracted to facilitate the first protrusion 8111 and the second protrusion 8211 to pass each other. On the other hand, the movable part 82 can be extended to ensure that the movable part 82 is always in contact with the fixed part 81, thereby achieving a damping effect.

[0108] In some embodiments, the movable part 82 includes an elastic member 821 and an adjusting member 822. The elastic member 821 is sleeved on the outer periphery of the first shaft 2 and is anti-rotationally engaged with the first shaft 2. The elastic member 821 is sandwiched between the adjusting member 822 and the fixed part 81. The adjusting member 822 is positionally adjustable on the first shaft 2 and is adapted to stop one end of the elastic member 821 and adjust the elastic force of the elastic member 821.

[0109] like Figure 3 As shown, the elastic element 821 can be a disc spring, which can be sleeved on the outer periphery of the first shaft 2 and assembled with the first shaft 2 to prevent rotation. The adjusting element 822 can be a nut, which can be threaded onto the first shaft 2. In use, the adjusting element 822 can stop at the right end of the elastic element 821, thus playing a limiting role, while the left end of the elastic element 821 can always be in contact with the fixed part 81, providing a damping effect. When it is necessary to adjust the elastic force of the elastic element 821, the adjusting element 822 can be rotated, allowing the user to adjust the damping effect according to their own needs.

[0110] In some embodiments, the fixed portion 81 is provided with a first stop portion 8121, and the first shaft 2 is provided with a second stop portion 21. The first stop portion 8121 is adapted to engage with the second stop portion 21 to limit the rotational stroke of the first shaft 2. Figure 4 As shown, the first stop 8121 can be fan-shaped and integrally formed with the fixed part 81, and the second stop 21 can also be fan-shaped and integrally formed with the first shaft 2. In use, the first stop 8121 can stop the second stop 21, thereby limiting the maximum rotational stroke of the first shaft 2.

[0111] In some embodiments, the linkage device 100 includes a housing 5, the housing 5 having a first contact surface 51, and the support member 4 having a second contact surface 41. In both the retracted position and the supported position, the first contact surface 51 is in contact with the second contact surface 41.

[0112] like Figure 11 As shown, the shell 5 can be cylindrical, and the first mating surface 51 can be an elliptical surface, such as... Figure 12 As shown, the support member 4 can also be generally cylindrical, and the second mating surface 41 can also be an elliptical surface. The support member 4 can rotate 180 degrees with the second axis 3. Thus, in the folded position, the first mating surface 51 and the second mating surface 41 can fit together, and the shell 5 and the support member 4 are assembled into a cylinder, enhancing integration and appearance, and facilitating storage. In the supported position, the second mating surface 41 rotates 180 degrees and fits together with the first mating surface 51. At this time, the shell 5 and the support member 4 form an angle, meeting the needs of support use.

[0113] In some embodiments, such as Figure 3 As shown, the second shaft 3 is connected to the support member 4 via a universal joint 10. The universal joint 10 includes a first joint 101 and a second joint 102. The first joint 101 is connected to the second shaft 3, and the second joint 102 is connected to the support member 4. The axial direction of the first joint 101 and the axial direction of the second joint 102 form a first angle, which can be an obtuse angle.

[0114] The second connector 102 is rotatably assembled with the housing 5. The first mating surface 51 and the second mating surface 41 both form a second angle with the axial direction of the second connector 102. The second angle can be a right angle, that is, the first mating surface 51 and the second mating surface 41 are both perpendicular to the axial direction of the second connector 102. This satisfies the transmission needs of different transmission shafts, and thus satisfies the transmission requirements between the second shaft 3 and the support member 4.

[0115] In some embodiments, the linkage device 100 includes a plurality of fixing members 9, the first shaft 2 is rotatably engaged with at least some of the fixing members 9, the second shaft 3 is rotatably engaged with at least some of the fixing members 9, and the first shaft 2 and the second shaft 3 are assembled to the housing 5 through the plurality of fixing members 9.

[0116] like Figure 2 and Figure 3 As shown, there can be four fixing members 9, namely the first member 91, the second member 92, the third member 93, and the fourth member 93. The first member 91 and the second member 92 can be assembled into the overlapping parts of the first shaft 2 and the second shaft 3 in the left-right direction. The first member 91 is located to the left of the second member 92 and is arranged at a distance from the second member 92. The first shaft 2 and the second shaft 3 are both rotatably engaged with the first member 91 and the second member 92. The limiting component 6 and the transmission component 7 can be located between the first member 91 and the second member 92. The limiting component 6 and the transmission component 7 can be separated by a partition, which can also be regarded as a fixing member 9.

[0117] like Figure 3 As shown, both the third piece 93 and the fourth piece 103 may include a sleeve portion. The third piece 93 may be located on the right side of the second piece 92. The second shaft 3 may be rotatably assembled inside the sleeve portion of the third piece 93. The fourth piece 103 may be located on the right side of the third piece 93. The second connector 102 may be rotatably assembled inside the sleeve portion of the third piece 93.

[0118] The first component 91, the second component 92, the third component 93, and the fourth component 103 are all connected to the housing 5, thereby realizing the installation and fixation of the linkage device 100 and the housing 5.

[0119] In some embodiments, such as Figure 5 As shown, the fixed part 81 can be separately configured. The fixed part 81 may include a first seat 811 and a second seat 812. The first seat 811 may be located to the left of the second seat 812. The first seat 811 may be fixedly connected to the housing 5. The second seat 812 may be rotatably connected to the first seat 811 via a pin. This allows the second seat 812 to have a certain degree of freedom, enhancing its adaptability to the movable part 82.

[0120] In some embodiments, the central angle corresponding to the guide groove 622 can be 90 degrees, and the total rotation angle of the first shaft 2 can be 130 degrees. When the first shaft 2 rotates within the transmission stroke, the stop member 61 moves along the guide groove 622. At this time, the first shaft 2 can rotate 90 degrees, and the support member 4 can rotate 180 degrees under the transmission action of the second shaft 3. Then the first shaft 2 can transition to the idle stroke and continue to rotate to 130 degrees. At this time, the first stop part 8121 and the second stop part 21 stop and limit the movement.

[0121] The following describes the device accessories according to embodiments of the present invention.

[0122] The equipment accessory in this embodiment of the invention includes a linkage device 100, which can be the linkage device 100 described in the above embodiments. For example... Figure 13 and Figure 14As shown, the equipment accessories may include a protective shell 200, which includes a first part 201 and a second part 202. The first part 201 is swayable relative to the second part 202. The first part 201 is connected to a flipping member 1. At this time, the flipping member 1 can be regarded as a part of the first part 201. The second part 202 is connected to a housing 5. The housing 5 can also be regarded as a part of the second part 202.

[0123] In use, the first part 201 can be flipped from back to front. The first part 201 will drive the flipping component 1, which in turn will drive the first shaft 2, the second shaft 3, and the support component 4 to rotate synchronously. When the first part 201 is flipped to the position shown... Figure 14 When in the position, the support member 4 can be supported between the tabletop and the lower edge of the first part 201, thereby providing support for the first part 201.

[0124] When it is necessary to store equipment accessories, the first part 201 can be flipped backward. During the idle stroke, only the first part 201, the flipping component 1, and the first shaft 2 rotate backward. After transitioning to the transmission stroke, the second shaft 3 and the support component 4 can rotate backward along with the first part 201 until the first part 201 overlaps on top of the second part 202. At this time, as Figure 13 As shown, support 4 is switched to the storage position.

[0125] It should be noted that the first part 201 and the second part 202 can be two independent parts, or the first part 201 and the second part 202 can be flexibly connected to meet the relative rotation requirements of the first part 201 and the second part 202.

[0126] In some embodiments, such as Figure 13 and Figure 14 As shown, there can be two linkage devices 100, and the two linkage devices 100 can share a single flipping component 1. In this case, the flipping component 1 is located between the two linkage devices 100, which can enhance symmetry and thus enhance the stability of the support.
