The invention provides a connecting shaft applied to wearable equipment.

The wearable equipment includes equipment main part and area body, equipment main part with one of them is equipped with the mounting groove, the relative both sides of mounting groove are provided with the jack, as shown in fig. 1 and 2, the connecting axle includes:

A housing 100 provided to the other of the apparatus main body and the belt body;

the two shaft bodies 200 are axially distributed in the shell 100; and

The rotating wheel 300 is movably arranged between the two shaft bodies 200 and has a first state and a second state; the axial direction of the shaft body 200 and the distribution directions of the two insertion holes are parallel, a first limiting part 310 and a second limiting part 320 are distributed on the outer periphery of the rotating wheel 300 along the circumferential direction, and the second limiting part 320 is concavely arranged inwards than the first limiting part 310;

In the first state, the first limiting portion 310 abuts against one end of the shaft body 200, and the other end of the shaft body 200 is inserted into the insertion hole; in the second state, the second limiting portion 320 abuts against one end of the shaft body 200, and the other end of the shaft body 200 exits from the insertion hole.

In an embodiment of the present invention, the end of the device body is provided with the mounting groove, and the end of the band body is provided with the connecting shaft, so that when the end of the band body is inserted into the mounting groove and the end of the shaft body 200 is inserted into the jack, the band body is fixedly connected to the device body, and when the end of the shaft body 200 is withdrawn from the jack, the end of the band body is pulled out of the mounting groove and the band body is separated from the device body. Specifically, when the rotating wheel 300 is in the first state, the first limiting portions 310 protruding from two sides of the rotating wheel are propped against opposite ends of the two shaft bodies 200, so that opposite ends of the two shaft bodies 200 are respectively inserted into the insertion holes on two sides of the installation groove, and the shaft bodies 200 cannot withdraw from the installation groove under the limitation of the insertion holes, thereby realizing the fixed connection of the device main body and the belt body. When the rotating wheel 300 is in the second state, the second limiting portions 320 concavely disposed at two sides of the rotating wheel will abut against the opposite ends of the two shaft bodies 200, so that the two shaft bodies 200 can move a distance in opposite directions, the opposite ends can withdraw from the insertion holes, the shaft bodies 200 can freely enter and exit the installation grooves, and the device body can be separated from the belt body.

When the wearable device is assembled, the first driving force rotates the rotating wheel 300 to the second state so as to insert the end of the belt body into the mounting groove, and when the belt body is inserted into the mounting groove in place, that is, when the end of the shaft body 200 is opposite to the jack, the rotating wheel 300 is driven to rotate to the first state, that is, the end of the shaft body 200 is inserted into the jack, and the belt body cannot be pulled out from the mounting groove, so that the belt body and the device body are fixedly connected. When the wearable device is disassembled, the rotating wheel 300 is driven to rotate, so that the rotating wheel 300 is switched from the first state to the second state, the end part of the shaft body 200 is withdrawn from the jack, and the belt body can be pulled out from the mounting groove and separated from the device main body.

In the invention, the rotating wheel 300 is driven to rotate, so that the rotating wheel is switched between the first state and the second state, and the end parts of the two shaft bodies 200 can be driven to be simultaneously inserted into or withdrawn from the insertion holes at the two sides of the mounting groove, so that the operation is very convenient, and the disassembly and assembly convenience and the disassembly and assembly efficiency of the equipment main body and the belt body can be improved. The connecting shaft can be used for detachably connecting the equipment main body and the belt body of the wearable equipment, and further, the equipment main body and the belt body can be conveniently and rapidly disassembled and assembled, so that the use experience of a user is improved.

Further, in this embodiment, as shown in fig. 2 to 4, the connecting shaft further includes a trigger member 400, a guide member 500, and a first elastic member 600, where the first elastic member 600 is disposed between the housing 100 and the rotating wheel 300, the trigger member 400 is sleeved on the guide member 500, the trigger member 400 and the guide member 500 are fixed relative to the housing 100 in the circumferential direction, and the guide member 500 is axially movably connected between the trigger member 400 and the rotating wheel 300. In this embodiment, the triggering member 400, the guiding member 500 and the first elastic member 600 act on the rotating wheel 300 in the axial direction to drive the rotating wheel 300 to rotate circumferentially, so that the user applies a pressing force on the triggering member 400 to drive the rotating wheel 300 to switch between the first state and the second state, which is very convenient. Specifically, when the user applies a force to the trigger 400, the rotating wheel 300 rotates circumferentially and moves axially, so that the first elastic member 600 is elastically deformed by the force, and when the external force on the trigger 400 is removed, the first elastic member 600 has a tendency to recover deformation, so as to help the rotating wheel 300 reset axially, and the guiding member 500 guides the axial movement of the rotating wheel 300 therein.

Further, in this embodiment, as shown in fig. 6, a first tooth groove 330 and a second tooth groove 340 surrounding the first tooth groove 330 are disposed on one side of the rotating wheel 300 in the axial direction, as shown in fig. 8, the guide 500 is provided with a first tooth protrusion 510 for axially engaging with the first tooth groove 330, as shown in fig. 7, the trigger 400 is provided with a second tooth protrusion 410 for axially engaging with the second tooth groove 340, in the first state and the second state, the same protrusion of the first tooth protrusion 510 engages with different slot positions of the first tooth groove 330, and the same tip of the second tooth protrusion 410 abuts against the slot opening of the chute wall of the different slot positions of the second tooth groove 340. Thus, the trigger piece 400 moves axially, can push the chute wall of the second tooth socket 340 by the second tooth protrusion 410, and can drive the first elastic piece 600 to deform elastically; the rotating wheel 300 can rotate under the action of the pushing force of the second tooth protrusion 410 and the reverse elastic force of the first elastic member 600, and is switched between the first state and the second state. Of course, in other embodiments, the rotating wheel and the trigger member or the guide member may be matched through other structures, one of the two matched components is provided with at least one sliding protrusion, and the other component is provided with a plurality of sliding grooves for sliding matching of the sliding protrusions, so that the shapes of the sliding protrusions and the sliding grooves are not limited.

In this embodiment, the first tooth slot 330 and the second tooth slot 340 are all configured as an annular structure, and the first tooth slot 330 and the second tooth slot 340 each have a plurality of slots, in other words, the plurality of slots of the first tooth slot 330 are annularly arranged on one axial side of the rotor 300, and the plurality of slots of the second tooth slot 340 are annularly arranged on the periphery of the first tooth slot 330. Without loss of generality, the plurality of slots of the first tooth slot 330 are continuously distributed, and the plurality of slots of the second tooth slot 340 are spaced apart. Further, the first tooth protrusion 510 may be provided with a plurality of protruding portions protruding along the axial direction, and the plurality of protruding portions of the first tooth protrusion 510 are continuously distributed and are in an annular array, and correspond to the plurality of slots of the first tooth slot 330 one by one, so that the first tooth protrusion 510 is meshed with the first tooth slot 330, and the second tooth protrusion 410 may also be provided with a plurality of protruding portions protruding along the axial direction, and the plurality of protruding portions of the second tooth protrusion 410 are in an annular array at intervals, and correspond to the plurality of slots of the second tooth slot 340 one by one, so that the second tooth protrusion 410 is matched with the second tooth slot 340.

Without loss of generality, in the present embodiment, a slot of the first tooth slot 330 and a slot of the second tooth slot 340 are both disposed corresponding to a first limiting portion 310 or a second limiting portion 320, that is, the first tooth protrusion 510 moves by a slot relative to the first tooth slot 330, and the second tooth protrusion 410 moves by a slot relative to the second tooth slot 340, so that the rotating wheel 300 can be switched between the first state and the second state once.

Further, in this embodiment, as shown in fig. 2 and 3, a third elastic member 900 is further disposed between the guide member 500 and the trigger member 400, and under the action of the third elastic member 900, the second tooth protrusion 410 is meshed with the second tooth slot 340, and has a tendency to disengage from the second tooth slot 340.

Further, in the present embodiment, as shown in fig. 1,4 and 5, the housing 100 is provided with a mounting opening 140 for the rotor 300 to be mounted in the housing 100. In addition, the first elastic member 600 may be also fitted into the housing 100 through the mounting opening 140. Specifically, the outer peripheral portion of the wheel 300 is inserted into the mounting opening 140 to limit the axial movement stroke of the wheel 300 by two port walls of the mounting opening 140 which are provided opposite to each other in the axial direction of the wheel 300.

In this embodiment, the driving assembly including the trigger 400, the guide 500 and the first elastic member 600 drives the rotating wheel 300 to rotate circumferentially, and the initial state of the rotating wheel 300 when the rotating wheel 300 is in the first state is referred to as the direction of the coordinate system shown in fig. 2, which describes how the driving assembly applies the force to the rotating wheel 300. The movement process of the wheel 300 after being stressed is described by taking one of the convex portions of the first tooth convex portion 510 (for convenience of description, referred to as a first convex portion) and one of the convex portions of the second tooth convex portion 410 (for convenience of description, referred to as a second convex portion) as an explanatory object.

It will be appreciated that when the wheel 300 is in the first state, the first tooth protrusion 510 engages with the first tooth slot 330, and each tip of the second tooth protrusion 410 is correspondingly located in the notch of each slot of the second tooth slot 340 and abuts against the inclined slot wall of each slot, that is, the first protrusion engages in one slot of the first tooth slot 330 (corresponding to the first slot), and the tip of the second protrusion abuts against the notch of the chute wall of one slot of the second tooth slot 340 (corresponding to the second slot). At this point, the trigger 400 is driven axially downward, the tip of the second lobe will push against the chute wall of the second slot to cause the wheel 300 to move axially downward and rotate circumferentially, while the circumferential rotation of the guide 500 is limited, which will cause the first lobe to slide along the chute wall of the first slot toward its slot. During this process, the first elastic member 600 is elastically deformed, the tip of the second protrusion moves toward the bottom of the groove along the wall of the chute of the second groove, so that the trigger 400 and the guide move toward each other in the axial direction, and the third elastic member 900 is compressed. When the wheel 300 moves downward to abut against the lower mouth wall of the mounting opening 140, the tip of the first protrusion slides to the notch of the first slot, and the tip of the second protrusion correspondingly slides to the slot bottom of the second slot, that is, the second protrusion engages with the second slot. At this time, the external force on the trigger piece 400 is removed, the upward elastic force of the third elastic piece 900 acting on the trigger piece 400 causes the second protrusion to be separated from the second slot upwards and to be suspended above the notch of the second slot, the guiding piece 500 will receive the downward force exerted by the third elastic piece 900, the rotating wheel 300 will receive the upward force exerted by the first elastic piece 600, and under the combined action of the first elastic piece 600 and the third elastic piece 900, the first tooth protrusion 510 will slide to the adjacent slot of the first slot. In this process, since the circumferential rotation of the guide 500 is restricted, the rotation of the wheel 300 continues to be circumferentially rotated in the previous direction and axially moved upward by the first elastic member 600 until the wheel 300 abuts against the upper wall of the mounting opening 140, the first tooth protrusion 510 is engaged with the groove, the wheel 300 stops rotating, and the second state is switched. At the same time, rotation of the wheel 300 will also cause the second tooth protrusion 410 to displace relative to the second tooth slot 340 in the circumferential direction so that the second protrusion can cross the slot wall of the second slot to oppose the slot opening of another adjacent slot, and the wheel 300 moves axially upward so that the tip of the second protrusion finally abuts against the slot opening of the slot wall of the slot. In other embodiments, the third elastic member 900 may not be disposed between the trigger 400 and the guide 500, and in other embodiments, the weight of the trigger 400 may be reduced as much as possible, so that the weight of the trigger is negligible, and after the trigger 400 is quickly pressed down, the trigger 400 may rebound under the elastic force of the rotating wheel 300, so that the second tooth protrusion 410 is separated from the second tooth groove 340.

To this end, the wheel 300 completes the process of switching from the first state to the second state. Further, in this embodiment, an even number of the first limiting portions 310 and an even number of the second limiting portions 320 are disposed on the outer periphery of the rotating wheel 300, and two ends of each two adjacent first limiting portions 310 are respectively connected by one second limiting portion 320. In this embodiment, the first limiting portions 310 and the second limiting portions 320 are staggered at the outer periphery of the rotating wheel 300, so that the rotating wheel 300 continues to rotate in the same direction, that is, the rotating wheel 300 can be switched from the second state to the first state only by undergoing the same process once again.

Further, in this embodiment, as shown in fig. 2 to 4, the connecting shaft further includes a second elastic member 700, and the shaft body 200 has a tendency to exit from the insertion hole after being inserted into the insertion hole under the action of the second elastic member 700. When the rotating wheel 300 is switched from the second state to the first state, the opposite ends of the two shaft bodies 200 are pushed by the first limiting parts 310 at the two sides of the rotating wheel 300 to move back to back, and the opposite ends of the two shaft bodies 200 can be simultaneously inserted into the insertion holes at the two sides of the mounting groove, and in this process, the second elastic piece 700 is elastically deformed. When the rotating wheel 300 is switched from the first state to the second state, the second limiting part 320 is opposite to the end part of the shaft body 200, the second elastic member 700 releases elastic potential energy, and the two shaft bodies 200 can move in opposite directions under the elastic force of the second elastic member 700 without excessive operation by a user until the opposite ends of the two shaft bodies 200 respectively abut against the second limiting parts 320 at two sides of the rotating wheel 300, and the opposite ends of the two shaft bodies 200 simultaneously withdraw from the insertion holes at two sides of the mounting groove. Of course, in other embodiments, the shaft body 200 may have a poking protrusion protruding from the housing 100 and slidably connected to the housing 100, and when the rotating wheel 300 rotates to the second state, the other end of the shaft body 200 may be withdrawn from the jack by poking the poking protrusion to make one end of the shaft body 200 abut against the second limiting portion 320.

Further, in this embodiment, as shown in fig. 2 to 4, the connecting shaft further includes a guiding cylinder 800 fixedly disposed in the housing 100, one of the shaft bodies 200 is correspondingly and axially movably disposed in the guiding cylinder 800, the second elastic member 700 is disposed in the guiding cylinder 800 and sleeved outside the shaft body 200, one end of the second elastic member 700 is connected to the shaft body 200, and the other end is connected to the wall of the guiding cylinder 800. The guide cylinder 800 provides a guiding function for the axial movement of the shaft body 200 so that the shaft body 200 can be moved in and out of the insertion hole, two ends of the second elastic member 700 are respectively connected to the shaft body 200 and the guide cylinder 800, and when the shaft body 200 and the guide cylinder 800 relatively move, the length of the second elastic member 700 is changed, and thus the elastic potential energy is changed. Of course, in other embodiments, the shaft body 200 may be directly installed in the housing 100, and one end of the second elastic member 700 is connected to the shaft body 200 and one end is connected to the housing 100.

Further, in the present embodiment, as shown in fig. 2 and 4, one end of the guide cylinder 800 near the rotating wheel 300 is provided with an open structure, and the other end is provided with an end wall 810; one end of the shaft body 200, which is close to the rotating wheel 300, is provided with a shaft protrusion 210, and the other end of the shaft body penetrates through the end wall 810; one end of the second elastic member 700 abuts against the boss 210, and the other end abuts against the end wall 810. The open end of the guide cylinder 800 is used for installing the boss 210, so that the boss 210 can be exposed at the end of the guide cylinder 800, and the first limiting portion 310 and the second limiting portion 320 of the rotating wheel 300 act, and the end of the shaft body 200 away from the boss 210 is movably penetrated through the end wall 810 of the guide cylinder 800. When the rotating wheel 300 is switched from the second state to the first state, the first limiting portion 310 pushes the boss 210 and partially extends into the open end of the guide cylinder 800, so that the end of the shaft body 200, which is far away from the boss 210, has a portion protruding from the end wall 810, and can be inserted into the insertion hole, and in this process, the second elastic member 700 is extruded to be elastically deformed. When the rotating wheel 300 is switched from the first state to the second state, the shaft protrusion 210 retracts to cooperate with the second limiting portion 320 under the action of the elastic force of the second elastic member 700, so as to drive the end of the shaft body 200 away from the shaft protrusion 210 to retract to a position where the end does not protrude from the end wall 810, or where the portion protruding from the end wall 810 is insufficient to be inserted into the insertion hole. Of course, in other embodiments, the two ends of the second elastic member 700 may be respectively engaged with the end wall 810 of the guide cylinder 800 and the boss 210 of the shaft body 200, or respectively connected to other portions of the guide cylinder 800 and the shaft body 200.

Further, in this embodiment, as shown in fig. 2 to 5, the housing 100 is provided with a yielding groove 110 opposite to the trigger piece 400, so that the trigger piece 400 has a portion exposed out of the housing 100, which can facilitate the user to apply an acting force to the trigger piece 400, thereby further improving the operation experience of the user. Of course, in other embodiments, the trigger 400 is not directly exposed outside the housing 100, but rather, an exposed component is connected to the trigger 400, and the user drives the trigger 400 to move axially by acting on the component.

Further, in the present embodiment, as shown in fig. 3 to 5, a first limiting protrusion 420 is disposed on the outer periphery of the trigger 400, a limiting blind groove 120 communicating with the yielding groove 110 is disposed on the inner wall of the housing 100, and the first limiting protrusion 420 is axially movably engaged with the limiting blind groove 120. The cooperation of the first limiting protrusion 420 and the limiting blind groove 120 is used for limiting the trigger piece 400 to rotate circumferentially relative to the housing 100 and guiding the trigger piece 400 to move axially relative to the housing 100, and can play a guiding role when the trigger piece 400 is pressed downwards or reset upwards. In addition, the limiting blind groove 120 limits the highest point of the axial movement of the trigger 400, so that the trigger 400 can be prevented from falling out of the housing 100.

Further, in this embodiment, as shown in fig. 5, the peripheral edge of the yielding groove 110 is provided with a secondary groove 130 corresponding to the first limit protrusion 420, so that the yielding groove 110 can allow the trigger piece 400 to be installed in the housing 100. The first limiting protrusion 420 is aligned with the auxiliary through slot 130, the trigger piece 400 can be smoothly installed into the housing 100 through the abdication through slot 110, and then the trigger piece 400 is rotated to align the first limiting protrusion 420 with the limiting blind slot 120, thereby completing the assembly of the trigger piece 400. In addition, the guide 500 or the first elastic member 600 may be installed in the housing 100 through the relief groove 110.

Further, in this embodiment, as shown in fig. 7 and 8, a second limiting protrusion 520 is disposed on a side of the guide member 500 facing away from the first tooth protrusion 510, and the trigger member 400 is correspondingly provided with a limiting groove 430, where the limiting groove 430 is used for slidably connecting the second limiting protrusion 520 in the axial direction and limiting the second limiting protrusion 520 in the circumferential direction. The engagement of the limit groove 430 and the second limit protrusion 520 serves to limit the relative movement of the trigger 400 and the guide 500 in the circumferential direction and to guide the relative movement of the trigger 400 and the guide 500 in the axial direction. Thus, the trigger 400 and the guide 500 are constrained from rotating circumferentially with the housing 100, while in the axial direction, the trigger 400 is able to move relatively to at least one of the guide 500 and the housing 100, thereby ensuring that the drive assembly is able to drive the wheel 300 effectively.

Further, in the present embodiment, as shown in fig. 6 and 8, the guide 500 is provided with a guide shaft 530 at a side where the first tooth protrusion 510 protrudes, the rotating wheel 300 is provided with a guide hole 350, and the guide shaft 530 is inserted into the guide hole 350. The axial movement coaxiality between the guide member 500 and the rotating wheel 300 is high under the cooperation of the guide shaft 530 and the guide hole 350, so that the engagement of the first tooth protrusion 510 and the first tooth groove 330 is guaranteed.

Further, in this embodiment, as shown in fig. 6 and 8, the guide shaft 530 is disposed through the guide hole 350, and the first elastic member 600 is disposed on a side of the rotating wheel 300 facing away from the first tooth slot 330 and is sleeved on the guide shaft 530. In this embodiment, the guide hole 350 is configured as a through hole for the guide shaft 530 to pass through, so that the guide shaft 530 can be sleeved by the first elastic member 600. Thus, the first elastic member 600 can be stably mounted in the housing 100 without dislocation. When the trigger 400 is pressed downward, the rotating wheel 300 is driven to move downward and axially, so as to compress the first elastic member 600, and after the external force applied to the trigger 400 is removed, the elastic force of the first elastic member 600 to the rotating wheel 300 can drive the rotating wheel 300 to move upward, so that each protruding part of the first tooth protrusion 510 is driven to slide into an adjacent groove. Of course, in other embodiments, the guide hole 350 may be a blind hole, and the first elastic member 600 may be disposed on the side of the runner 300 where the first tooth slot 330 is disposed, and the first elastic member 600 is elongated to have elastic potential energy when the trigger 400 drives the runner 300 downward.

Further, in this embodiment, as shown in fig. 4 and 5, the housing 100 includes a sleeve 101 and a cover 102, one end of the sleeve 101 is opened, the cover 102 is covered on the opening of the sleeve 101, one shaft 200 is movably inserted into the cover 102, and the other shaft 200 is movably inserted into an end wall 810 of the sleeve 101 opposite to the cover 102. It can be appreciated that the mounting opening 140, the yielding groove 110, the limiting blind groove 120, the auxiliary groove 130 and other structures are all formed on the sleeve 101. In this embodiment, the casing 100 is configured as a split structure, which is convenient for assembling the connecting shaft, and after each component is installed into the sleeve 101, the cover 102 is sealed to cover the opening of the sleeve 101, so as to protect each component inside, thereby ensuring the structural stability of the connecting shaft. Specifically, a plurality of engaging protrusions 150 are disposed at intervals on the inner peripheral wall of the open end of the sleeve 101, a plurality of engaging grooves 160 are correspondingly disposed on the outer peripheral edge of the cover 102, and one engaging protrusion 150 is correspondingly engaged with one engaging groove 160, so that the cover 102 is fixedly connected to the sleeve 101. Without loss of generality, in this embodiment, two shaft bodies 200 and two third elastic members 900 may be installed in a one-to-one correspondence manner into two guide cylinders 800, one of the guide cylinders 800 is installed into the sleeve 101, then the first elastic member 600 is installed into the mounting opening 140 or the yielding channel 110, then the rotating wheel 300 is installed into the mounting opening 140, after the rotating wheel 300 is installed, the other guide cylinder 800 is installed into the sleeve 101, then the guiding member 500 and the triggering member 400 are installed into the yielding channel 110, and finally the opening of the sleeve 101 is sealed by the cover 102, thus completing the assembly of the connecting shaft.
