[0035] With the development of science and technology, power mechanisms are applied to the field of door locks and serve as a power source for multiple connecting parts. In the prior art, each connecting part is equipped with a corresponding power mechanism, so multiple connecting parts need to be equipped with multiple power mechanisms and multiple output motors, resulting in a higher overall cost of the door lock.

[0036] See also Figure 1-Figure 4 The present invention provides a power mechanism, which includes a housing 1, an output motor 2, a transmission mechanism 3, a detection transmission member 4, a detection member 5, and a transmission gear shaft 6. The output motor 2, the transmission mechanism 3, the detection transmission member 4, the detection member 5, and the transmission gear shaft 6 are all installed on the housing 1.

[0037] The output motor 2 serves as a power source of the power mechanism and outputs power to the outside. The output motor 2 may be a brushless output motor, a stepping output motor, or the like.

[0038] See also Figure 1-Figure 4 One end of the transmission mechanism 3 is connected to the output motor 2, and the other end is connected to the detection transmission member 4 through the transmission gear shaft 6, and the power of the output motor 2 is transmitted to the detection transmission member 4 to realize the rotation of the detection transmission member 4.

[0039] The transmission mechanism 3 includes a plurality of transmission members 31 , which are meshed in sequence and connect the output motor 2 , the transmission gear shaft 6 and the detection transmission member 4 to drive the transmission gear shaft 6 and the detection transmission member 4 to rotate simultaneously.

[0040] Among them, the plurality of transmission members 31 are meshed in sequence and stacked in sequence along the height direction, making full use of the thickness space in the housing 1, and improving the space utilization rate of the plurality of transmission members 31, thereby realizing a miniaturized design of the power mechanism. In addition, the plurality of transmission members 31 are meshed in sequence, and extend in sequence along the length direction of the housing 1, and expand in sequence along the width direction of the housing 1, thereby improving the space utilization rate of the plurality of transmission members 31, thereby realizing a miniaturized design of the power mechanism.

[0041] The plurality of transmission members 31 are respectively a first gear 311 , a second gear 312 , a third gear 313 , and a fourth gear 314 , and the first gear 311 , the second gear 312 , the third gear 313 , and the fourth gear 314 are meshed in sequence.

[0042] The transmission gear shaft 6 is connected with at least two connecting members, and selectively drives each of the connecting members to swing. Optionally, the three connecting members are respectively a transmission member of the main lock tongue, a transmission member of the secondary lock tongue, and a stopper of the main lock tongue.

[0043] In addition, the transmission gear shaft 6 is connected to the other end of the transmission mechanism 3, and rotates under the drive of the transmission mechanism 3 to drive multiple connecting parts connected to the peripheral side of the transmission gear shaft 6, so that multiple connecting parts can be driven by one output motor 2 to operate, avoiding the separate use of multiple output motors 2, reducing the overall cost of the door lock, and reducing the overall space of the power mechanism.

[0044] The transmission gear shaft 6 comprises a shaft body 61, a first boss 62 and a second boss 63, wherein the first boss 62 and the second boss 63 are respectively located at different heights in the transmission gear shaft 6 and at different sides of the transmission gear shaft 6. The first boss 62 protrudes outward along the outer side wall of the shaft body 61, and the second boss 63 protrudes upward along the outer side wall of the shaft body 61. The first boss 62 and the second boss 63 act on corresponding connecting members in different directions. Optionally, the first connecting member 200 is a rotatable swing rod or a gear, one end of which abuts against the first boss 62, and the second connecting member 300 is a paddle, which is engaged with the second boss 63.

[0045] In addition, the shaft body 61 is rotatably mounted on the housing, and the shaft body 61 is provided with a gear portion 611, which outwardly exceeds the first boss 62 and the second boss 63 along the circumferential direction of the shaft body 61. The gear portion 611 is meshed with the other end of the transmission mechanism 3, so that the shaft body 61 is driven by the transmission mechanism 3 and the drive output motor 2 to rotate, so that the first bosses 62 and the second bosses 63 act on the corresponding transmission parts of the main lock tongue, the transmission parts of the secondary lock tongue and the stopper of the main lock tongue during the rotation process.

[0046] The first boss 62 is convexly arranged on the outer side wall of the rotating shaft body 61. Optionally, the first boss 62 protrudes outward along the outer side wall of the rotating shaft body 61. The first boss 62 can abut against two first connecting members 200 at the same time. The two first connecting members 200 are arranged at intervals in the height direction and act on different parts of the first boss 62. The first connecting member 200 is arranged relative to the first boss 62 and is driven by the first boss 62 to adjust its position. At this time, the two first connecting members 200 are respectively the transmission member of the main lock tongue and the stopper of the main lock tongue.

[0047] There are multiple first bosses 62, and the multiple first bosses 62 are arranged at intervals along the circumferential direction of the shaft body 61 and form an angle, so that the multiple first bosses 62 can abut against the first connecting member 200 when the shaft body 61 is rotating forward or reverse, and can adjust the movement direction of the first connecting member 200 when the shaft body 61 is rotating forward or reverse.

[0048] In addition, the first boss 62 is provided with a support 64 along the circumferential direction of the rotating shaft body 61, and the side surface of the support 64 has a position difference with the first boss 62 along the circumferential direction of the rotating shaft body 61; the support 64 acts on the corresponding connecting member alone, wherein the support 64 can act as a gear, the first boss 62 can act as a rocker arm, and the operation of different time periods can be achieved through the first boss 62 and the support 64.

[0049] The support 64 has a penetration area above, through which the connecting member acted upon by the first boss 62 is penetrated, so as to avoid interference between the connecting member acting on the support 64 and the connecting member acting on the first boss 62, thereby ensuring that the transmission gear shaft 6 acts on multiple connecting members at the same time.

[0050] The second boss 63 is convexly arranged on the outer side wall of the rotating shaft body 61 and is located on different sides from the first boss 62; the second boss 63 and the first boss 62 rotate with the rotation of the rotating shaft body 61 and act on corresponding connecting members respectively, so that the first boss 62 and the second boss 63 act on different connecting members in parts, so that the first boss 62 and the second boss 63 act on corresponding connecting members with the rotation of the rotating shaft body 61, and then multiple connecting members make corresponding position adjustments based on the rotation of the same transmission gear shaft 6, so that the transmission gear shaft 6 acts on multiple connecting members at the same time, and improves the compatibility of the transmission gear shaft 6. Among them, the second connecting member 300 is arranged relative to the second boss 63, and is driven by the second boss 63 to adjust its position.

[0051] Specifically, one first connecting member 200 may be a swing rod 200a, and the other first connecting member 200 may be a gear 200b, wherein when the door lock is about to unlock the door body, the transmission gear shaft 6 needs to rotate counterclockwise, at which time, the two first bosses 62 and the second boss 63 rotate along with the counterclockwise rotation of the shaft body 61, and the first boss 62 first abuts against the swing rod 200a, and drives the swing rod 200a to swing, so as to realize that the main lock tongue connected to the gear 200b is transformed from a restricted state to an active state, and then, the first boss 62 abuts against the gear 200b while abutting against the swing rod 200a, and drives the gear 200b, so that the main lock tongue is adjusted from an extended state to a retracted state, so as to realize the unlocking of the main lock tongue relative to the door body. Then, the second boss 63 abuts against the second connecting member 300, and drives the second connecting member 300 to swing, so as to retract the secondary lock tongue.

[0052] In addition, when the door lock is about to lock the door body, the transmission gear shaft 6 needs to rotate clockwise. At this time, the support 64 of the other first boss 62 will first abut the swing rod 200a and drive the swing rod 200a to swing, so as to realize the main lock tongue connected to the gear 200b from the restricted state to the active state. Then, the other first boss 62 abuts the gear 200b while abutting the swing rod 200a, and drives the gear 200b, so that the main lock tongue is adjusted from the contracted state to the extended state, and the main lock tongue is locked relative to the door body. Then, the second connecting member 300 extends to the door body based on its own elasticity to realize the locking of the secondary lock tongue relative to the door body.

[0053] The detection transmission member 4 is connected to the transmission gear shaft 6, and rotates driven by the transmission gear shaft 6, the transmission mechanism 3 and the output motor 2, wherein a transition transmission member 7 is connected between the transmission gear shaft 6 and the detection transmission member 4; the transmission gear shaft 6 drives the detection transmission member 4 to rotate via the transition transmission member 7, and the transmission ratio between the transmission gear shaft 6 and the detection transmission member 4 is ensured by the transition transmission member 7, and the transmission ratio between the transmission gear shaft 6 and the detection transmission member 4 is not affected.

[0054] The transition transmission member 7 comprises a first transmission part 71 and a second transmission part 72 which rotate coaxially, the outer diameter of the first transmission part 71 is larger than that of the second transmission part 72; the first transmission part 71 engages with the transmission gear shaft 6; the second transmission part 72 engages with the detection transmission member 4.

[0055] See also Figure 1-Figure 4 The detection member 5 is installed on the detection transmission member 4, and detects the rotation position of the detection transmission member 4, thereby determining the rotation position of the transmission mechanism 3, so as to realize the detection of different positions of the transmission mechanism 3, thereby facilitating the power mechanism to drive multiple connecting members.

[0056] The detection member 5 is provided with a rotating portion 51 , and position sensing is performed on the rotating portion 51 ; the rotating portion 51 is sleeved on the upper side of the detection transmission member 4 , and rotates synchronously with the rotation of the detection transmission member 4 .

[0057] Optionally, the transmission member 31 , the detection transmission member 4 , and the transition transmission member 7 are all gears.
