Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door locks, in particular to a handle lock and an intelligent door. BACKGROUND

[0002] With the development of science and technology, the application of intelligent locks is becoming more and more extensive. The intelligent lock is a more intelligent lock than the mechanical lock in terms of user identification, security, manageability and convenience, and is an execution component for locking doors in an access control system. The technology of the intelligent lock is relatively mature, and it can use a non-mechanical key as a user identification ID, such as a fingerprint lock, an iris recognition access control, a magnetic card, a radio frequency card, and a TM card. The intelligent lock has high security and convenience, and is a composite lock of advanced technology.

[0003] There are various types of intelligent locks, although some are non-contact pure electric door locks, but horizontal handle type door locks or handle locks are still widely used. The handle lock includes a handle that can be twisted, and the reset is generally achieved by a torsional spring.

[0004] When the torsional spring is installed together with other parts, a fit clearance can occur. In addition, even if the fit is good, the torsional spring will deform after long-term use, such as 50,000 twists, which can still cause a fit clearance. The fit clearance of the torsional spring can cause the handle to have a virtual position, and then can cause the handle to shake, or even can cause the handle to be unable to open the door.

[0017] In this way, the rotating stroke of the handle assembly is controlled; it is beneficial for reliable operation, and the stress on the torsional spring can be reduced.

[0018] In some embodiments, the third limiting part is coaxially arranged with the first limiting part and has an integrated structure; the positions of the two stop parts are symmetrical with respect to the second limiting part.

[0019] In this way, the structure is simple; the force acting point is at the same circumferential position, and the force is balanced.

[0020] In some embodiments, the handle assembly comprises a handle and a reset seat, the handle is rotationally connected to the panel and extends out of the panel, and the reset seat is connected to the handle and located on the inner side of the panel; the first limiting part is arranged on the reset seat.

[0021] In this way, the handle can be operated, and then the reset of the handle is ensured by the first limiting part and the reset seat.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] Reference Figure 1 , Figure 1 A lever lock in the present application is shown. In an exemplary embodiment, the lever lock 1000 includes a faceplate 1, a lever assembly 2, a first limiting part 31, a torsion spring 4, and a second limiting part 51.

[0043] The lever assembly 2 is rotationally connected to the faceplate 1. For the convenience of description, a space rectangular coordinate system XYZ is established. The rotation axis of the lever assembly 2 can be parallel to the Y-axis direction, and the rotation surface can be parallel to the XZ plane. The lever assembly 2 can be assembled by multiple parts.

[0044] The first limiting part 31 can be detachably connected to the lever assembly 2, or can be a part of the lever assembly 2, or a part of an integral part of the lever assembly 2. The first limiting part 31 can rotate relative to the faceplate 1 with the rotation of the lever assembly 2. The position of the first limiting part 31 deviates from the axis of the lever assembly 2.

[0045] Reference Figure 2 The torsion spring 4 includes a first torsion arm 41 and a second torsion arm 42. Before assembly, there can be no pre-tightening force between the two torsion arms; after assembly, the first torsion arm 41 and the second torsion arm 42 can have a pre-tightening force due to the change in the circumferential position. In combination with Figure 3 As shown in FIG. 1, in the assembled lever lock 1000, the torsion spring 4 is limited to the lever assembly 2, and the first torsion arm 41 can rotate counterclockwise, and the second torsion arm 42 can rotate clockwise relative to the first torsion arm 41, and the first torsion arm 41 and the second torsion arm 42 are clamped on both sides of the first limiting part 31. The distance between the first torsion arm 41 and the second torsion arm 42 continuously changes. Exemplarily, the first torsion arm 41 and the second torsion arm 42 respectively extend along the radial direction of the lever assembly 2, and then the distance between the first torsion arm 41 and the second torsion arm 42 increases with the position outward along the radial direction. In other embodiments, the first torsion arm 41 and the second torsion arm 42 are inclined inward, and then the distance between the first torsion arm 41 and the second torsion arm 42 decreases with the position outward along the radial direction.

[0046] The first torsion arm 41 and the second torsion arm 42 can extend substantially linearly. Each torsion arm can include two segments that are offset from each other, which can be offset in the XZ plane or can have an offset in the Y-axis direction.

[0047] The second limiting part 51 is arranged on the panel 1 and is supported between the first torsion arm 41 and the second torsion arm 42. In combination Figure 4 As shown, when the handle assembly 2 is rotated in the counterclockwise direction shown in the figure, the first limiting part 31 is away from the second limiting part 51, and the first limiting part 31 can drive the first torsion arm 41 to rotate together, while the second limiting part 51 abuts against the second torsion arm 42. The torsion spring 4 can generate a torsion force. When the handle assembly 2 is released, the torsion force of the torsion spring 4 can drive the handle assembly 2 to reset, the second torsion arm 42 is limited by the second limiting part 51, and the first torsion arm 41 drives the first limiting part 31 to rotate clockwise until the two torsion arms clamp the first limiting part 31 or the second limiting part 51.

[0048] The second limiting part 51 and the first limiting part 31 can be arranged side by side, and the distance therebetween along the radial direction of the handle assembly is adjustable. Exemplarily, the position of the second limiting part 51 is adjustable. Referring to Figure 5 and Figure 7 In some cases, one of the second limiting part 51 and the first limiting part 31 cannot contact the torsion spring 4 on both sides, Figure 5 In the first limiting part 31 and the first torsion arm 41 have a first interval d1, Figure 7 In the second limiting part 51 and the first torsion arm 41 have a second interval d2, which causes the first limiting part 31 to be able to shake circumferentially relative to the second limiting part 51, and then the handle assembly 2 relative to the panel 1 will have a virtual position, and in the virtual position, the torsion force of the torsion spring 4 cannot be felt during rotation.

[0049] Since the distance between the second limiting part 51 and the first limiting part 31 is adjustable, as shown in the case Figure 5 The second limiting part 51 can be adjusted upward along the Z-axis direction, so that the distance between the first torsion arm 41 and the second torsion arm 42 is smaller, and then the first limiting part 31 can be clamped; as shown in the case Figure 7 The second limiting part 51 can be adjusted downward, so that the two sides of the second limiting part 51 abut against the torsion arms of the torsion spring 4. The second limiting part 51 and the first limiting part 31 both contact the first torsion arm 41 and the second torsion arm 42 and are then limited by the torsion spring 4, and cannot shake circumferentially at will, avoiding the generation of a virtual position of the handle assembly 2 relative to the panel 1. The handle lock 1000 has reliable structure, stable performance, and good user experience.

[0050] Referring to Figure 1 , Figure 3 and Figure 4The second limiting part 51 is located radially on the outer periphery of the first limiting part 31, simplifying the structural layout of the handle lock 1000. The torsion arm of the torsion spring 4 can be a simple straight line shape, and the outer diameter of the second limiting part 51 is larger than the outer diameter of the first limiting part 31. Both the second limiting part 51 and the first limiting part 31 can be cylindrical structures, and the torsion arm of the torsion spring 4 can be along the common tangent direction. The specific contact point can be varied according to the adjustment position. The cylindrical structure is simple and easy to manufacture, and the torsion spring 4 will deform when the handle assembly 2 rotates, ensuring that the torsion arm is driven. For example, the second limiting part 51 and the first limiting part 31 can only be designed with a section of arcuate outer periphery at the contact area, and the two arcuate surfaces on both sides of the second limiting part 51 or the two arcuate surfaces on both sides of the first limiting part 31 can be non-concentric.

[0051] In other embodiments, the second limiting portion 51 may bypass a part of the handle assembly 2 in the Y-axis direction, or the handle assembly 2 may have an arc-shaped clearance groove, such that the second limiting portion 51 is located inside the first limiting portion 31. The outer diameter of the second limiting portion 51 may be smaller than the outer diameter of the first limiting portion 31.

[0052] refer to Figure 1 The panel 1 can be a one-piece housing, capable of housing electronic components, mechanical parts, etc. The second limiting part 51 can slide radially connected to the panel 1, allowing for sufficient adjustment distance and precise position adjustment. The second limiting part 51 can be positioned directly above the handle assembly 2 along the Z-axis. The panel 1 includes a plate 11 and a sliding groove 12. The plate 11 has a screw hole 101 corresponding to the sliding groove 12. The screw hole 101 can be a blind hole to avoid penetrating the plate 11. The sliding groove 12 guides the sliding of the second limiting part 51.

[0053] The handle lock 1000 also includes a slider 52 and a locking screw 53. The slider 52 is fixed to the second limiting part 51, and the two can form an integral torsion spring holder. The parts themselves have a compact structure and good strength. Along the Z-axis, the slider 52 is longer to stably slide and connect to the slide groove 12; along the Y-axis, the second limiting part 51 protrudes from the slider 52. The slider 52 has a waist hole 501 corresponding to the screw hole 101. The locking screw 53 passes through the waist hole 501 and connects to the screw hole 101. The locking screw 53 can be tightened to lock and position the slider 52 and the second limiting part 51 on the panel 1, or it can be loosened to adjust the position of the waist hole 501 relative to the locking screw 53, that is, to adjust the position of the second limiting part 51 relative to the panel 1 and the first limiting part 31. The handle lock 1000 has a simple structure; all components are located inside the panel 1 to avoid the outside from affecting the internal mechanism.

[0054] refer to Figure 6 The slider 52 and the second limiting part 51 move upward, and the lower end of the waist hole 501 corresponds to the locking screw 53, which can... Figure 5 The torsion spring 4 shown has an excessively large tension angle; it should be adjusted appropriately. (Reference)Figure 8 The slider 52 and the second limiting part 51 move downwards, and the upper end of the waist hole 501 corresponds to the locking screw 53, which can... Figure 7 The torsion spring 4 shown has an excessively small opening angle and should be adjusted appropriately.

[0055] refer to Figure 1 The handle lock 1000 also includes a third limiting part 32. The third limiting part 32 and the first limiting part 31 can be respectively disposed on the handle assembly 2. Exemplarily, the third limiting part 32 and the first limiting part 31 are coaxially disposed and are a single-piece reversing limiting post; the single-piece structure is simple to install and has good structural strength. The panel 1 includes two stop parts 13 spaced apart along the circumference of the handle assembly 2. The stop parts 13 are used to limit the rotational position of the third limiting part 32 and the handle assembly 2. Figure 4 In the structure shown, the handle assembly 2 has not yet rotated to its final position and can continue to rotate. The handle assembly 2 can rotate forward and backward, and the rotation stroke is controlled; this facilitates reliable operation and also reduces the force on the torsion spring 4.

[0056] refer to Figure 3 When no external force is applied, the third limiting part 32 is coaxial with the first limiting part 31 and located directly above the rotation axis. When the handle assembly 2 is in position, the torsion spring 4 and the stop part 13 exert forces on the handle assembly 2 at the same point in the circumference, and the handle assembly 2 is in force balance. The positions of the two stop parts 13 are symmetrical with respect to the second limiting part 51. In some other embodiments, they may be asymmetrical.

[0057] Handle assembly 2 includes a handle 21 and a reset seat 22. The handle 21 is rotatably connected to and extends out of panel 1. The reset seat 22 is located inside panel 1. The reset seat 22 is connected to the handle 21. Exemplarily, the handle assembly 2 also includes a first screw 23 for fixing the reset seat 22 to the handle 21. A first limiting part 31 is disposed on the reset seat 22. When not controlled by the operator, the handle 21 can be approximately parallel to the X-axis direction, facilitating a horizontal grip; the handle 21 can be operated, for example, by pressing down to unlock, and then, after releasing the handle 21, the torsion spring 4 drives the first limiting part 31 and the reset seat 22 to ensure the handle 21 resets.

[0058] The reset base 22 can be a centrally symmetrical structure, for example, the outer periphery is roughly rhomboid. During assembly, the upper and lower ends have the same structure, which is conducive to quick installation and helps to avoid installation errors.

[0059] The reset seat 22 can include a connecting plate 221, a supporting cylinder 222, a square shaft sleeve 223, and a buckle 224. The reset seat 22 can be an integral structure, the connecting plate 221 is fixed to the supporting cylinder 222 and the square shaft sleeve 223 respectively, and the supporting cylinder 222 is fixed with the plurality of buckles 224. The parts have compact structure and good strength. The connecting plate 221 is connected to the first limiting part 31, so that the first limiting part 31 and the supporting cylinder 222 have a spacing, so as to set the torsion spring 4. The square shaft sleeve 223 is arranged in the supporting cylinder 222, which can be used for profile matching with the square shaft (not shown), and then the handle 21 can be used to control the lock body (not shown). The buckle 224 and the connecting plate 221 can be connected to both ends of the supporting cylinder 222 along the Y-axis direction, the torsion spring 4 is sleeved on the supporting cylinder 222, and the torsion spring 4 is clamped by the buckle 224 and cannot fall off. When installing, the torsion spring 4 can be installed by using a needle-nose pliers.

[0060] The handle lock 1000 can further include a bearing 61 and a pressing plate 62. The handle 21 can be rotatably connected to the panel 1 through the bearing 61. The pressing plate 62 covers the bearing 61, and the pressing plate 62 can be fixed to the panel 1 by a second screw 63, or the second screw 63 can not penetrate the panel 1. The distance between the reset seat 22 and the panel 1 can be designed by setting the thickness of the pressing plate 62. The reversing limiting column can be arranged in the connecting plate 221, for example, a middle threaded connection, the third limiting part 32 is located on the front side of the connecting plate 221, and the first limiting part 31 is located on the rear side of the connecting plate 221.

[0061] Reference Figure 9 The present application provides an intelligent door 3000. The intelligent door 3000 includes a door body 2000 and the aforementioned handle lock 1000. The handle lock 1000 can be used to open and close the door body 2000. The panel 1 is installed on the door body, and the handle 21 can be outside the door body 2000. The panel 1 can be configured with a fingerprint recognition, password recognition, face recognition and other functional modules.

[0062] By adjusting the position of the second limiting part 51, the virtual position of the handle 21 caused by the production tolerance and use deformation of the torsion spring 4 is eliminated. The handle lock 1000 is simple to operate, safe, easy to install, compact and reliable. The intelligent door 3000 includes the handle lock 1000, has good quality, good operation experience, and good performance. The virtual position of the handle 21 is long-term controllable, the user experience is improved, and the debugging cost of the torsion spring 4 is reduced.

In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.

Sub-steps of each step can also be executed in staggered manner. The above described various forms of flow can be used, and the steps can also be reordered, added or deleted, as long as the desired results of the technical solutions provided in the present application can be achieved, and the present application is not limited in this regard.
