DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Example 1
[0033] See also Figure 1 、 Figure 2 and Figure 3 The clutch mechanism 100 of the smart lock handle includes: a handle base installed on the rear panel of the door, the clutch mechanism 100 includes a gear box 1, a core shaft 2 and a handle 3, and the axis lines of the gear box 1, the core shaft 2 and the handle 3 coincide with each other, so that the torque generated by the handle 3 can be efficiently transmitted to the core shaft 2 through the wheel box 1. The front end of the gear box 1 has a transmission part 11, which is an approximately annular structure. The outer side of the annular structure is extended outward along the axis direction to set an active grinding disc 111. A handle 3 is provided on the main body 12 at the rear end of the gear box 1, and the handle 3 is used to rotate and unlock; the driven grinding disc 21 at one end of the core shaft 2 can be engaged with the active grinding disc 111 on the transmission part 11 of the gear box 1, and the output shaft section 22 at the other end of the core shaft 2 is connected to the lock cylinder; when in use, the handle 3 is manually rotated. Since the active grinding disc 111 on the transmission part 11 at the front end of the gear box 1 and the driven grinding disc 21 of the core shaft 2 are engaged together, the handle 3, the gear box 1 and the core shaft 2 rotate synchronously, thereby realizing manual unlocking of the smart lock handle.
[0034] like Figure 1 and Figure 5As shown, the annular elastic ring 4 is located at the front end of the transmission member 11 of the gearbox 1. Its function is to separate the driven grinding disc 21 of the core shaft 2 from the active grinding disc 111 of the transmission member 11 of the gearbox 1. Specifically, an annular step 112 is provided on the outer surface of the transmission member 11 of the gearbox 1, surrounding the active grinding disc 111. The annular step 112 is adapted to fit the elastic ring 4. Multiple tapered holes 113 are provided circumferentially spaced on the annular step 112 of the transmission member 11. Countersunk screws in these tapered holes secure the transmission member 11 to the front end of the gearbox 1. During use, when the elastic wave ring 4 is compressed along the axial direction, one side of the elastic wave ring 4 is pressed against the annular step 112 of the transmission part 11 of the gear box 1, and the outer surface of the active grinding disc 111 of the transmission part 11 on the gear box 1 protrudes outward from the inner ring of the elastic wave ring 4 along the axial direction, and engages with the driven grinding disc 21 of the core shaft 2. The gear box 1 and the core shaft 2 rotate synchronously to achieve unlocking; when the elastic wave ring 4 is elastically reset along the axial direction, the force generated by the elastic reset can separate the active grinding disc 111 on the transmission part 11 of the gear box 1 from the driven grinding disc 21 of the core shaft 2.
[0035] like Figure 1 、 Figure 5 and Figure 6 As shown, the outer ring diameter size and the inner ring diameter size of the active grinding disc 111 on the transmission member 11 are substantially equal to the outer ring diameter size and the inner ring diameter size of the driven grinding disc 21 on the core shaft 2, respectively, so that the driven grinding disc 21 and the active grinding disc 111 are fully engaged, thereby improving their reliability and stability of operation.
[0036] like Figure 4 and Figure 6 As shown, a motor (not shown in the figure) and a gear set 13 are provided in the body 12 of the gear box 1. The output main shaft of the motor is connected to the input end of the gear set 13, and the output end of the gear set 13 is connected to the rotating shaft 14. When the motor is energized, the torque generated by the motor is output outward through the gear set 13 and the rotating shaft 14. The rotating shaft 14 of the gear box 1 is pivotally connected to the input shaft section 23 on the core shaft 2, and the torque generated by the motor of the gear box 1 can be output to the core shaft 2 to achieve electric unlocking. A bearing 15 is provided between the inner ring of the transmission member 11 of the gear box 1 and the outer ring of the rotating shaft 14, thereby realizing the rotational connection between the transmission member 11 and the rotating shaft 14, ensuring that the transmission member 11 and the rotating shaft 14 are assembled without interference. It should be noted that the specific structural form of the gear set 13 in the gear box 1 of this embodiment can be achieved by using existing technology, so it will not be described in detail herein.
[0037] like Figure 1 、 Figure 3 、 Figure 7 and Figure 8As shown, the rear end of the gearbox 1 has a body 12 that is approximately cylindrical, with a gearbox motor mounted within its interior. On the cylindrical bottom wall, two tapered grooves 121 are provided, with openings and gradually increasing depth from the center to the edge of the bottom wall. The two tapered grooves 121 are located at the center of the bottom wall of the gearbox 1 body 12 and are arranged symmetrically. The handle 3 has a cylindrical cavity that mates with the gearbox 1 body 12. Within the cylindrical cavity of the handle 3, two tapered blocks 31 are provided, with gradually increasing width and height from the center of the bottom wall to the side walls. The two tapered blocks 31 of the handle 3 slide in engagement with the two tapered grooves 121 of the gearbox 1 body 12, allowing the handle 3 and gearbox 1 to move relative to each other along the central axis. Limiting notches 122 are provided on the corresponding side walls of the main body 12 of the gear box 1, parallel to the axis direction; limiting ridges 32 are provided on the opposite inner walls in the cavity of the handle 3, extending along the axis direction; the front part of the limiting ridge 32 slides relatively in the limiting notches 122, so that the handle 3 and the gear box 1 rotate synchronously.
[0038] When in use, in the initial state, the two cone blocks 31 are coupled with the two cone grooves 121 respectively. When the handle 3 is rotated, the cone block 31 in the cylindrical cavity of the handle 3 rotates around the central axis, and the large end of the cone block 31 gradually slides from the bottom of the large mouth of the cone groove 121 along the side wall of the cone groove 121 to the top of the large mouth of the cone groove 121. The body 12 of the gear box 1 moves away from the bottom wall of the cavity of the handle 3, and the active grinding disc 111 on the transmission part 11 at the front end of the gear box 1 engages with the driven grinding disc 21 of the core shaft 2; the handle 3 continues to rotate, driving the core shaft 2 to rotate, and the rotation of the core shaft 2 drives the square rod to move, thereby realizing manual unlocking (i.e. opening the door).
[0039] The clutch mechanism of the smart lock handle of the present invention adopts a mechanical cooperation mode between a handle and a gear box. The operating handle is rotated to drive the gear box to move along the axis direction and rotate with the rotation of the handle. The active grinding disc and the driven grinding disc are meshed to transmit the torque of the handle through the core shaft and the gear box to achieve manual unlocking. The design structure is simple and the integration is high, which greatly reduces the production cost of the smart lock.
[0040] Example 2
[0041] See also Figure 9 、 Figure 10 and Figure 11A clutch includes a housing 200 for mounting the clutch mechanism 100 of a smart lock handle. The output shaft section 22 of the spindle 2 of the clutch mechanism 100 extends outward from a front cover 201 of the housing 200. A square hole for connecting to the square rod of the lock cylinder is provided at the distal end of the output shaft section 22 along the axis. The body 12 of the gearbox 1 of the clutch mechanism 100 extends outward from a rear cover 202 of the housing 200 and is connected to the handle 3 of the clutch mechanism 100. Multiple lugs 203 extend outward from the sidewalls of the front and rear covers 201, 202 of the housing 200. These lugs 203 are used to mount the clutch on the handle base 300 of the door rear panel.
[0042] The clutch of the utility model is installed on the door rear handle seat, and the clutch mechanism is integrated into the handle, which reduces the cost of the electronic door lock and reduces the size. During installation, there is no need to disassemble the lock core box in the door, and non-destructive clutch installation can be achieved, which is convenient for clutch rear installation and maintenance costs.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
