DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] Example 1: Please refer to Figure 1-7 As shown, the present embodiment provides an anti-stuck toggle shaft device 100, which includes a main body 110 for installing and supporting components, a latch member 111 movably installed on the main body 110, a reset component 114 connected to the latch member 111, a toggle component 112 and a transmission component 113; wherein the transmission component 113 is rotatably installed on the main body 110 and connected to the latch member 111, and the toggle component 112 is rotatably installed on the main body 111, wherein when the toggle component 112 is rotated to a first position, it can come into contact with the transmission component 113 and drive the transmission component 113 to rotate, and the transmission component 113 drives the latch member 111 to perform a linear motion; when the toggle component 111 continues to rotate to a second position, it can be completely separated from the transmission component 113, and the latch member 111 is reset under the action of the reset component 114.

[0040] In the present embodiment, specifically, the reset assembly 114 includes a return spring 141, which is disposed between the latch member 111 and the main body 110, and is used to generate an elastic force between the latch member 111 and the main body 110, so that when the latch member 111 is driven by the transmission assembly 113 and performs a linear motion, the return spring 141 between the latch member 111 and the main body 110 is stretched, and the elastic force of the return spring 141 on the latch member 111 is increased, so that when the toggle assembly 111 continues to rotate to the second position and can be completely disengaged from the transmission assembly 113, the latch member 111 is reset under the action of the return spring 141.

[0041] In this embodiment, please refer to Figure 5-10 As shown, the toggle assembly 112 includes a driving member 121 installed on the main body 110 and rotatable, and the transmission assembly 113 includes a pivot shaft 151 installed on the main body 110 and a follower 122 that can rotate around the pivot shaft 151. The driving member 121 can contact the follower 122 on the main body 110 when it is rotated to a first position and can drive the follower 122 to rotate counterclockwise. The follower 122 can drive the latch member 111 to perform reciprocating linear motion by rotating, and can be disengaged from the follower 122 when it is rotated to a second position. The latch member 111 is reset under the elastic force, wherein the first position is on one side of the follower 122, and the second position is on the other side of the follower 122; when the driving member 121 rotates on one side of the follower 122, the rotation area of ​​the side can be adjusted according to the rotation of the follower 122. Figure 3 The figure shows the lower right side of the follower 122. The driving member 121 starts to rotate from the initial state, rotates clockwise and gradually approaches the follower 122 until it abuts against the follower 122 at the first position. At this time, the driving member 121 continues to rotate clockwise and generates a mutual force on the follower 122, causing the follower 122 to rotate counterclockwise. Since the follower 122 is connected to the latch member 111 by design, as shown in FIG. Figure 4 As shown, when the follower 122 rotates counterclockwise, the other end of the follower 122 rotates and can drive the latch member 111 to move in a straight line into the main body 110, thereby completing the contraction action of the latch member 111; further, when the driving member 121 continues to rotate clockwise and reaches the maximum angle of the follower 122 rotating counterclockwise, the rotation position of the driving member 121 is in the critical area between the first position and the second position, as shown in FIG. Figure 7As shown, the contact area between the driving member 121 and the driven member 122 is minimized; further, when the driving member 121 continues to rotate and slides into the other side of the driven member 122 from the critical area between the first position and the second position, the driven member 122 and the driving member 121 are completely separated from each other, so the elastic force between the latch member 111 and the main body 110 causes the driven member 122 to rotate in the opposite direction, that is, clockwise, and the clockwise rotation of the driven member 122 is completed instantly under the support of the elastic force, so the latch member 111 also moves instantly along a straight line to the outside of the main body 110 during this process, thereby returning to the initial state, as shown in FIG. Figure 8 As shown; it can be understood that when the driving member 121 rotates clockwise, when the driving member 121 has not reached the first position, the driving member 121 has not contacted the driven member 122, and when the driving member 121 has not reached the second position, the driving member 121 has not contacted the driven member 122. When the driving member 121 reaches the first position or the second position and contacts the driven member 122 and then disengages from the driven member 122, except for the instantaneous rotation under the elastic force at the moment of disengagement of the driven member 122 and the driving member 121, which causes the latch member 111 to move instantaneously at the same time, the follower 122 is in a stationary state, and therefore the latch member 111 is also in a stationary state.

[0042] When the driving member 121 rotates on the other side of the driven member 122, the rotation area of ​​the side can be Figure 8 The upper side of the driven member 122 is shown, and the driving member 121 starts to rotate from the initial state, rotates counterclockwise and gradually approaches the driven member 122 until it reaches the second position and abuts against the driven member 122. Fig. 9 As shown, at this time, the driving member 121 continues to rotate counterclockwise and generates an interaction force on the driven member 122, causing the driven member 122 to rotate clockwise. Since the other end of the driven member 122 is designed to be connected to the latch member 111, the elastic force of the latch member 111 will change when the driven member 122 rotates counterclockwise, and when the driven member 122 rotates clockwise, the other end of the driven member 122 is separated from the latch member 111. Therefore, in this state, the driven member 122 will rotate clockwise, and the other end of the driven member 122 will rotate in a direction away from the main body 110. At this time, the latch member 111 is in a stationary state without moving. The main purpose of this process is to make the driving member 121 return to the rotating area on the lower side of the driven member 122 to repeatedly drive the latch member 111; this completes a cycle, and so on and so forth, driving the latch member 111 to make intermittent horizontal movements.

[0043] Further, when the driving member 121 continues to rotate counterclockwise and reaches the maximum angle of the driven member 122 rotating counterclockwise, the rotation position of the driving member 121 is in the critical area between the first position and the second position, such as Figure 8 As shown, the contact area between the driving member 121 and the driven member 122 is minimized; further, when the driving member 121 continues to rotate and slides from the critical area between the first position and the second position into the lower area of ​​the driven member 122, at this time, since the driven member 122 and the driving member 121 are separated from each other, and the driven member 122 is elastically connected to the main body 110, the driven member 122 is subjected to the elastic force applied by the reset component 114, thereby prompting the driven member 122 to rotate in the opposite direction, that is, to rotate counterclockwise and return to the position of the initial state, and the counterclockwise rotation of the driven member 122 is completed instantly under the support of the elastic force It can be understood that when the driving member 121 rotates counterclockwise, when the driving member 121 has not reached the second position, the driving member 121 does not contact the driven member 122; and further, when the driving member 121 reaches the second position and continues to rotate, when the driving member 121 contacts and separates from the driven member 122, since the latch member 111 does not participate in this state, the latch member 111 is in a stationary state, and except for the moment when the driven member 122 and the driving member 121 separate, which will produce an instantaneous rotation under the elastic force and restore to the initial state, the driven member 122 is in a stationary state.

[0044] In other embodiments, when the driving member 121 rotates on the other side of the driven member 122, the rotation area of ​​the side can be Figure 8 It is shown as the upper side of the follower 122, and the driving member 121 starts to rotate from the initial state, and can also be set to rotate clockwise and gradually approach the follower 122 until it is back in the lower area of ​​the follower, and in this process, the driving member 121 does not make contact with the follower 122, so that the follower 122 does not change. At this time, the latch member 111 is in a static state without moving, and the main purpose of this process is to make the driving member 121 return to the rotating area on the lower side of the follower 122 to repeatedly drive the latch member 111; this completes a cycle, and so on and so forth, driving the latch member 111 to make intermittent horizontal movements.

[0045] Optionally, in the present embodiment, the driving member 121 is configured as a driving tongue structure, and the driven member 122 is configured as a driven tongue structure, that is, the driving member 121 and the driven member 122 both extend in relative directions to form abutment tongues; in some other embodiments, the driving member 121 and the driven member 122 can also be designed as structures of other abutment forms.

[0046] Preferably, the main body 110 in this embodiment includes a base 131 and a cover plate 132 fixedly mounted on the base 131, and a limiting channel 11a for limiting the latch member 111 is reserved between the cover plate 132 and the base 131. The latch member 111 is limited by the limiting channel 11a so that the latch member 111 can only reciprocate in a straight line in the horizontal direction, thereby preventing the latch member 111 from moving up and down during the movement, causing problems in the use of the rotating shaft device, thereby improving the user experience.

[0047] Please refer to Figure 1-4 As shown, preferably, the transmission assembly 113 also includes a rotating arm 124 arranged around the pivot shaft 151, and one end of the rotating arm 124 is provided with a first embedded groove 14a for the follower 122 to be embedded, and the follower 122 is located in the first embedded groove 14a and can rotate relative to the rotating arm 124 toward the first direction; it can be understood that the purpose of providing the first embedded groove 14a is to promote the tightness of the fit between the follower 122 and the rotating arm 124, and to reduce the assembly volume of the anti-stuck toggle shaft device 100, so that the overall structure is more compact; and the first embedded groove 14a has a movable space toward the first direction, and the movable space allows the follower 122 to be located in the first embedded groove 14a and rotate relative to the rotating arm 124 toward the first direction. The setting of this structure allows the follower 122 to be located in the first embedded groove 14a and rotate relative to the rotating arm 124 toward the first direction. The pivot structure formed between the rotating arm 124 in the first direction can enhance the mobility of the transmission component 113 and prevent the transmission component 113 and the toggle component 112 from getting stuck; further, the follower 122 is located in the first locking groove 14a and can drive the rotating arm 124 to rotate in the second direction. It can be understood that by designing that the first locking groove 14a does not have a movable space in the second direction, when the follower 122 rotates in the first locking groove 14a around the pivot axis 151 in the second direction, since the first locking groove 14a does not have a movable space in the second direction, the follower 122 will drive the rotating arm 124 to rotate in the second direction in the first locking groove 14a, so that the rotating arm 124 can drive the latch member 111 to move in a straight line.

[0048] It can be understood that the follower 122 and the latch member 111 are connected by the rotating arm 124, so that the follower 122 and the latch member 111 are indirectly connected, which prevents the follower 122 from being directly connected or abutting against the latch member 111, causing the other end to be detached from the latch member 111 due to excessive rotation angle during the rotation of the follower 122, resulting in damage to the anti-stuck and toggling shaft device 100; this structure is conducive to the coordination between the follower 122 and the latch member 111 as well as the driving member 121.

[0049] Please refer to Figure 1-4As shown, preferably, the reset assembly 114 also includes a first torsion spring 142 arranged around the pivot shaft 151, and the first torsion spring 142 is located on one side of the rotating arm 124 on the pivot shaft 151. One end of the first torsion spring 142 is engaged with the rotating arm 124, and the other end is engaged with the main body 110. It can be understood that the purpose of providing the first torsion spring 142 is to enable the rotating arm 124 to have an elastic reset function, that is, when the follower 122 rotates, it will drive the rotating arm 124 to rotate, and the rotating arm 124 will be affected by the first torsion spring when rotating. 142, so the greater the rotation angle of the rotating arm 124, the greater the elastic force exerted by the first torsion spring 142 on it. When the driving member 121 and the driven member 122 are separated from each other, the driven member 122 is not subjected to the force exerted by the driving member 121, so that the rotating arm 124 is no longer rotated by the force exerted by the driving member 121. At this time, the elastic force of the first torsion spring 142 on the rotating arm 124 causes the rotating arm 124 to be affected by the elastic force, thereby quickly resetting to prepare for the next rotation action.

[0050] Please refer to Figure 1-4 As shown, preferably, the reset assembly 114 also includes a second torsion spring 143 arranged around the pivot shaft 151, and the follower 122 is provided with a second embedded groove 14b for the second torsion spring 143 to be installed. The second torsion spring 143 is embedded and connected with the follower 122 at one end in the second embedded groove 14b, and is embedded and connected with the rotating arm 124 at the other end; it can be understood that the purpose of providing the second torsion spring 143 is to play an elastic reset role for the rotation of the follower 122 in the first embedded groove 14a; that is, when the driving member 121 rotates on the upper side of the driven member 122 and gradually approaches the driven member 122 until it reaches the second position and abuts against the driven member 122, then the driving member 121 continues to be stressed and rotates When the driven member 122 is driven to rotate clockwise, the driven member 122 will rotate clockwise in the first clamping groove 14a. When the driven member 122 rotates, it is affected by the elastic action of the second torsion spring 143. Therefore, the greater the rotation angle of the driven member 122, the greater the elastic force exerted by the second torsion spring 143 on it. When the driving member 121 and the driven member 122 are separated from each other, the driven member 122 is no longer affected by the force applied by the driving member 121. At this time, the elastic force of the second torsion spring 143 on the driven member 122 causes the driven member 122 to be affected by the elastic force, thereby quickly resetting in the first clamping groove 14a to prepare for the next rotation action.

[0051] Please refer to Figure 1-10As shown, this embodiment provides an anti-stuck toggle shaft device 100. On the basis of Embodiment 1, the toggle assembly 112 also includes a rotating cover 123 installed on the driving member 121, and the rotating cover 123 and the driving member 121 are integrally formed. The purpose of setting the rotating cover 123 is to increase the rotation control area of ​​the driving member 121 to avoid operating difficulties due to the small operating area of ​​controlling the driving member 121 during the operation of the driving member 121, and also to avoid direct operation of the driving member 121.

[0052] In summary, the utility model provides an anti-stuck toggle shaft device, which can contact the transmission component and drive the transmission component to rotate when the toggle component rotates to the first position, and the transmission component drives the latch to perform linear motion; when the toggle component continues to rotate to the second position, it can completely disengage from the transmission component, and the latch is reset under the action of the reset component. The transmission component can drive the latch to perform reciprocating linear motion, thereby avoiding the self-locking and jamming problems caused by friction, wear and design defects between the common components of the toggle shaft device, ensuring that the toggle shaft device can achieve the toggle function of automatic reset when avoiding jamming, thereby improving the continuous operation ability of the toggle shaft device under complex and changeable working conditions, and bringing better user experience.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
