Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically relating to a drive mechanism and a lock. Background Technology

[0002] Existing electric locks use a motor to drive spring compression to achieve locking and unlocking. However, the springs in existing technologies mainly bear shear force during movement, making them prone to breakage and leading to problems such as locks being normally open or normally closed. CN220769126U discloses a gear transmission mechanism and a lock with this mechanism, in which the spring is changed from being subjected to shear force to being subjected to compression force, solving the problem of easy spring breakage, significantly increasing fatigue cycles, extending the spring's lifespan, and making it more durable and reliable.

[0003] However, in the aforementioned prior art, the spring end (i.e., the spring foot) is locked inside the rectangular abutment ring. Since the spring is a metal part and the rectangular abutment ring is a plastic part, the spring end will wear down the rectangular abutment ring when the motor rotates. After long-term use, the spring end is prone to cutting or damaging the plastic part, causing the spring stroke to change, thereby weakening the spring action and affecting the positioning rate of the rectangular abutment ring, which in turn leads to the failure of the switch lock. Utility Model Content

[0004] The purpose of this invention is to provide a drive mechanism and a lock to solve the above-mentioned technical problems.

[0005] This application provides a driving mechanism. The driving mechanism includes:

[0006] A rotating shaft, one end of which is provided with a rotating shaft gear for cooperating with a power component;

[0007] A slider is fitted onto a rotating shaft; the slider is provided with a spring groove and a protrusion.

[0010] The outer wall of the rotating shaft is provided with a protrusion between the helices of the inserted spring;

[0011] When the rotating shaft rotates, the spring drives the slider to move, which in turn drives the drive block to move.

[0012] In one embodiment of this application, the slider is cube-shaped.

[0013] In one embodiment of this application, the slider has shaft holes at both ends for the rotating shaft to pass through.

[0014] In an embodiment of the present application, the notch of the spring groove is arranged on the side of the sliding block.

[0015] In an embodiment of the present application, the protrusion is arranged on one side of the notch.

[0016] In an embodiment of the present application, the sliding block is made of plastic material, and the driving block is made of metal material.

[0017] Accordingly, the present application provides a lock, comprising:

[0027] The limiting assembly comprises:

[0028] a limiting notch for accommodating the annular groove; and

[0029] a baffle arranged on one side of the tail end of the rotating shaft, for limiting the tail end of the rotating shaft.

[0030] The present application has the following beneficial effects:

[0031] Different from the prior art, the application provides a driving mechanism. The driving mechanism comprises: a rotating shaft, one end of which is provided with a rotating shaft gear for cooperating with a power assembly; a sliding block, which is sleeved on the rotating shaft; the sliding block is provided with a spring groove and a protrusion; a spring, which is sleeved on the rotating shaft and located in the spring groove; and a driving block for connecting a lock head, which is arranged at a notch of the spring groove; the driving block is provided with a containing hole for containing the protrusion and a corresponding containing groove for containing spring feet at two ends of the spring; the outer wall of the rotating shaft is provided with a protrusion inserted between the springs; when the rotating shaft rotates, the sliding block is driven to move by the spring, so as to drive the driving block to move.

Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0045] The application provides a driving mechanism and lock, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0046] Referring to Figure 1 and Figure 2 In an embodiment, the driving mechanism comprises: a rotating shaft 1, one end of which is provided with a rotating shaft gear 11 for cooperating with a power assembly 200; a sliding block 2, which is sleeved on the rotating shaft 1; the sliding block 2 is provided with a spring groove 21 and a convex block 22; a spring 3, which is sleeved on the rotating shaft 1 and located in the spring groove 21; and a driving block 4 for connecting a lock head, which is arranged at the slot opening of the spring groove 21; the driving block 4 is provided with an accommodating hole 41 for accommodating the convex block 22 and a corresponding accommodating groove 42 for accommodating the spring foot 31 at both ends of the spring 3; the outer wall of the rotating shaft 1 is provided with a convex part 13 inserted between the spirals of the spring 3; when the rotating shaft 1 rotates, the sliding block 2 is driven to move by the spring 3, thereby driving the driving block 4 to move.

[0047] In the embodiment, the slider 2 is matched with the protrusion 22 and the accommodating hole 41 on the driving block 4, so that the slider 2 and the driving block 4 form a connecting body and can move synchronously; the spring 3 is arranged in the slider 2, the spring feet 31 at both ends of the spring 3 are accommodated in the corresponding accommodating grooves 42 on the driving block 4; and the rotating shaft 1 is arranged in the spring 3, and the protrusion 13 on the rotating shaft 1 is inserted between the springs 3, so that the spring 3 can be extruded by the protrusion 13 when the rotating shaft 1 rotates, thereby driving the slider 2 and the driving block 4 to move synchronously, that is, driving the lock head connected with the driving block 4 to move, so as to complete unlocking or locking.

[0048] In the embodiment, the spring feet 31 at both ends of the spring 3 are accommodated in the corresponding accommodating grooves 42 on the driving block 4, that is, the mounting mode of the spring 3 is changed compared with the prior art, and the spring feet 31 no longer cause abrasion to the slider 2. In addition, when mounting, the spring feet 31 only need to be directed to the outside of the spring groove 21, and then the spring 3 is inserted into the spring groove 21, so that the mounting of the spring 3 is completed, and the mounting is more convenient compared with the prior art.

[0049] Optionally, the slider 2 is made of plastic, and the driving block 4 is made of metal.

[0050] Further, the slider 2 can be a cube. The slider 2 is provided with shaft holes 23 through which the rotating shaft 1 passes at both ends. The slot opening of the spring groove 21 is arranged on the side surface of the slider 2. The protrusion 22 is arranged on one side of the slot opening.

[0051] On the basis of the above embodiment, referring to Figures 3 to 6 , the embodiment of the application further provides a lock, which comprises a base 100, a power assembly 200 arranged on the base 100, and a driving mechanism 300 as described above mounted on the base 100; wherein the base 100 is provided with a limiting assembly 110 for limiting the axial direction of the rotating shaft 1, a first sliding groove 120 for the slider 2 to move in the axial direction of the rotating shaft 1, and a second sliding groove 130 for the driving block 4 to move in the axial direction of the rotating shaft 1.

[0052] In the embodiment, the power assembly 200 can drive the rotating shaft 1 to rotate, thereby driving the slider 2 to move in the first sliding groove 120 and the driving block 4 to move in the second sliding groove 130.

[0053] Further, referring to Figure 4 , the lower side surface of the slider 2 is provided with a clamping block 24 clamped into the first sliding groove 120.

[0054] Optionally, the power assembly 200 comprises: a motor 210, which is installed in the motor groove 140 on the base 100, and a driving gear 211 is arranged on the output shaft of the motor 210; and a transmission gear 220, which is installed on the gear shaft 150 on the base 100 and is used for engaging the driving gear 211 and the rotating shaft gear 11.

[0055] In the embodiment, the end of the rotating shaft 1, on which the rotating shaft gear 11 is installed, is provided with an annular groove 12; the limiting assembly 110 comprises: a limiting gap 111, which is used for accommodating the annular groove 12; and a baffle 112, which is arranged on one side of the tail end of the rotating shaft 1 and is used for limiting the tail end of the rotating shaft 1.

[0056] In the embodiment, the two groove walls of the annular groove 12 are stepped surfaces and can be clamped on both sides of the limiting gap 111. In order to prevent the gear from being locked, the width of the annular groove 12 can be slightly larger than the width of the limiting gap 111, so that the rotating shaft 1 can have a certain displacement space in the axial direction. In order to prevent the annular groove 12 from running out of the limiting gap 111 due to excessive axial force of the rotating shaft 1, the baffle 112 can limit the tail end of the rotating shaft 1. The baffle 112 reduces the motion inertia of the rotating shaft 1, limits the shaking space, and further reduces the abrasion.
