Description

TECHNICAL FIELD

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

[0002] Common doors can be divided into left opening doors and right opening doors according to the opening and closing directions. When installing a lock on a door, an installer needs to adjust the handle direction of the lock to adapt to the different opening and closing direction requirements of the door.

[0003] In the prior art, some door lock manufacturers have designed a quick reversing mechanism, such as patent application CN110566053A. The main structure of this mechanism is composed of a lock panel, a handle, a handle return spring, a reversing plate, a reversing screw, a fixing nut and a relaxation washer. When the installer reverses the handle at the user's home, he only needs to unscrew the reversing screw from the reversing plate, rotate the handle by 180 degrees, and then tighten the reversing screw. This structure is quick and simple to operate, but in order to achieve the effect that the handle does not shake before and after reversing, the spring clamping on both sides of the panel, the spring clamping column on one side of the reversing plate, the reversing screw and the handle spring legs on both sides need to be six points in a line, which puts high requirements on the production and manufacturing of each part.

[0004] In order to solve the above problems, the current common practice of door lock manufacturers is to determine the size of the panel, the reversing plate and the reversing screw, and to adjust the angle of the handle return spring legs on both sides to achieve the effect that the handle does not shake. However, this method also introduces a new problem - during door lock assembly and production, each batch needs to be re-adjusted. And because the angle of the handle return spring legs is unstable, even if the springs in the same batch, there is a high probability that the handle will shake, at which time it needs to be re-adjusted. This greatly reduces the production efficiency of the door lock manufacturer, increases the assembly cost of the door lock manufacturer and reduces the market competitiveness. SUMMARY

[0005] To solve the problems in the prior art, the purpose of the present application is to provide a handle reversing mechanism, a lock and an intelligent door lock, which can meet the demand for quick reversing of the handle, and through the cooperation between the supporting assembly and the stabilizing structure, the handle is not prone to shaking in all directions before and after reversing, which can reduce rework adjustment, reduce production and inventory costs of manufacturers and enhance user experience.

DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0041] Unless otherwise defined, technical terms or scientific terms used in the present application shall have the common meaning understood by one of ordinary skill in the art to which the present application pertains.

The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right", and the like are used only to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships can also change accordingly.

[0042] To solve the problems in the prior art, the present application aims to provide a handle reversing mechanism, a lock, and an intelligent door lock, which can ensure that the handle does not shake before and after reversing through the cooperation between the supporting assembly and the stabilizing structure, so as to enable the installation personnel to quickly reverse and reduce the rework cost of accessories, thereby being beneficial to enhancing the user experience.

[0043] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The handle reversing mechanism is used in a lock with a handle 3, and the handle reversing mechanism comprises a reversing plate 1 following the handle 3, and further comprises a supporting assembly 2.

[0044] The supporting assembly 2 comprises a sliding plate 21 and a base 22 which are movably connected. The sliding plate 21 is directly or indirectly connected with the reversing plate 1, so that the sliding plate 21 can be relatively displaced with the base 22 along a movement direction (for the sake of distinction, the movement direction is also referred to as a first movement direction in the present embodiment) under the driving of the rotation of the reversing plate 1.

[0045] The stabilizing structure 4 is configured between the slide plate 21 and the base 22, wherein the stabilizing structure 4 comprises a first elastic part 42 and a rolling part 41 configured at the movable connection between the slide plate 21 and the base 22. The first elastic part 42 provides an elastic force in a direction different from the aforementioned movement direction (i.e., the first movement direction) (for the sake of distinction, the second movement direction is also referred to in the embodiment), and abuts against the rolling part 41 to contact the slide plate 21 or the base 22, so that the rolling part 41 is movably connected in a rolling manner on the slide plate 21 or the base 22.

[0046] The steering plate 1 in the handle reversing mechanism can be connected with the handle 3 and rotate with the handle 3. Any possible connection mode can be adopted between the steering plate 1 and the handle 3 to achieve the following effect.

[0047] Optionally, the handle 3 and the steering plate 1 can be connected at least in a clamping manner. For example, as shown in Figure 2 and Figure 4 , the first protrusions 1-3 can be arranged to approach each other in the central region of the steering plate 1, and the assembly gaps 31 matched with the first protrusions 1-3 can be arranged in the axial direction of the handle 3. The first protrusions 1-3 of the steering plate 1 can be inserted into the handle 3 through the assembly gaps 31 to form the clamping connection as described above.

[0048] Optionally, on the basis of the clamping connection or other possible connection modes, the structure can be further reinforced by possible structures such as the fastener 13 and the lock washer 12 to improve the structural stability. The implementation modes of the structure fastener 13 and the lock washer 12 will be exemplarily introduced in the following embodiments of the lock.

[0049] Optionally, the steering plate 1 can be directly or indirectly connected with the slide plate 21 to drive the slide plate 21 to move. For example, as shown in Figure 2 , the steering plate 1 can abut against the slide plate 21. The handle 3 can be lifted or pressed, and the slide plate 21 can be driven to slide up and down relative to the base 22 through the rotation of the steering plate 1.

[0050] Optionally, the movement direction of the slide plate 21, i.e., the first movement direction, can be at least the a direction, and of course can also be the direction opposite to the a direction, as long as the relative displacement between the slide plate 21 and the base 22 can be achieved to complete the reversing process of the handle 3, which conforms to the inventive concept of the present application.

[0051] Optionally, the steering plate 1 can have a symmetrical structure to better adapt to the reversing requirement of the handle 3. That is, the connection / position relationship between the steering plate 1 and other components (such as the slide plate 21) is the same or similar before and after the handle 3 changes the direction, so that the influence on other structures can be reduced as much as possible in the case of reversing the handle 3.

[0052] Optionally, as shown in Figure 2 and Figure 4 , the turning plate 1 has two opposite initial abutting surfaces 1-1 and two opposite turning guide surfaces 1-2 with curvature, and the initial abutting surfaces 1-1 are adjacent to the turning guide surfaces 1-2.

[0053] In the case that the lock has been installed and the handle 3 is in the daily use state, at least a partial area of one of the initial abutting surfaces 1-1 abuts against the slide plate 21. Exemplarily, when the handle 3 is not subjected to external force, the handle 3 can be kept horizontal, at which time the whole of one of the initial abutting surfaces 1-1 abuts against the slide plate 21. As shown in Figure 2 and Figure 4 , in the case that the handle 3 is in the use state, the handle 3 can be oriented to the left side or the right side. When the handle 3 is oriented to the left side, the initial abutting surface 1-1 on one side abuts against the slide plate 21. When the handle 3 is oriented to the right side, the opposite initial abutting surface 1-1 abuts against the slide plate 21. When the user wants to open the door, he can press down the handle 3 to drive the turning plate 1 to rotate, so that only a partial area of the initial abutting surface 1-1 (e.g. the area near the junction of the initial abutting surface 1-1 and the turning guide surface 1-2 in Figure 4 ) abuts against the slide plate 21. It is to be noted that in the daily use state, the degree of pressing down of the handle 3 can be limited by the limiting member 7, which will be further described below.

[0054] In the case that the handle needs to be installed in the reverse direction, in the process of turning the handle 3, the initial abutting surface 1-1 and the turning guide surface 1-2 can abut against the slide plate 21 at different time points. Exemplarily, taking the case that the handle 3 is oriented to the left side as an example, the handle 3 is first kept in the horizontal position, at which time the initial abutting surface 1-1 on one side can abut against the contact surface of the slide plate 21. When the handle 3 is continuously pressed down to drive the turning plate 1 to rotate together with the handle 3, the turning guide surface 1-2 on one side can abut against the contact surface of the slide plate 21. If the handle 3 is continuously pressed to rotate 180 degrees to the right side, the initial abutting surface 1-1 on the other side can abut against the contact surface of the slide plate 21. The handle 3 can be continuously rotated by 360 degrees to return to the state of being oriented to the left side initially, and the process of rotation is similar to the process of rotating by 180 degrees, which will not be described herein.

[0055] With such an implementation, the handle can better adapt to the requirement of reverse installation, and the installer or the user can smoothly rotate the handle whether in the process of reverse installation or in the daily use state, which helps to realize quick reverse installation and improve the user experience.

[0056] The aforementioned first direction of motion differs from the second direction of motion, thus allowing the first elastic part 42 to provide at least one force in another direction, or at least a component force perpendicular to the first direction of motion. This ensures that the rolling part 41 abuts against the slide plate 21 or the base 22, compensating for the gap between them. With this implementation, the slide plate and the base can smoothly undergo relative displacement in the first direction of motion while maintaining relative stability in other directions. This results in greater stability for the steering plate and the handle, preventing wobbling, especially when the handle is in a horizontal position.

[0057] For example, the first direction of motion and the second direction of motion can be perpendicular to each other, such as... Figure 2 Figure 6 , Figure 8 As shown, the direction of motion of the skateboard 21, i.e., the first direction of motion, can be direction a, and the second direction of motion can be... Figure 2 The b direction in the middle can also be Figure 6 and Figure 8 In the direction of b.

[0058] Optionally, such as Figure 3 As shown, the stabilizing structure 4 can be set on the base 22, on the slide plate 21, or on both the base 22 and the slide plate 21. As long as it can improve the stability when displacement occurs between the slide plate 21 and the base 22, it is in line with the inventive concept of this application and is not limited herein.

[0059] In some embodiments of the present invention, such as Figure 2 and Figure 6 As shown, the base 22 has two first grooves 221 corresponding to the two opposite sides of the slide plate 21, forming a space to accommodate the slide plate 21. The first grooves 221 have a length direction consistent with the first direction of movement, allowing the slide plate 21 to move relative to the base along the first direction of movement. For example, as... Figure 2 and 6 As shown, the length direction of the first groove 221 can be the same as or opposite to direction a, and this application does not limit it.

[0060] As previously mentioned, the stabilizing structure 4 can be mounted on the base 22 and / or the slide plate 21. When mounted on the base 22, optionally, as... Figure 2 , Figure 3 , Figure 6 and Figure 7As shown in the figures, the stabilizing structure 4 is mounted on the first groove body 221. The rolling part 41 is movably arranged at the other end of the first elastic part 42 to contact the slide plate 21. As an example, one or more mounting holes 223 for mounting the stabilizing structure 4 can be arranged on the inner wall of the first groove body 221, and the stabilizing structure 4 is inserted into the inner wall or partially embedded in the first groove body 221 through the mounting hole 223.

[0061] Optionally, as shown in the figures, Figure 6 and Figure 8 The stabilizing structure 4 can be arranged in pairs on the first groove body 221, or randomly distributed on the first groove body 221, for example, two stabilizing structures 4 are arranged on the inner wall of the first groove body 221 on one side of the base 22, and three stabilizing structures 4 are arranged on the inner wall of the first groove body 221 on the other side.

[0062] Optionally, as shown in the figures, Figure 3 and Figure 7 The rolling part 41 is configured as a spherical structure, and the first elastic part 42 is configured as a first spring. The first spring is further sleeved with a bushing 43 for containing the first spring. The bushing 43 is fixedly embedded on the inner wall of the first groove body 221, and the spherical structure protrudes from the opening end of the bushing 43 to the inner wall of the first groove body 221. As an example, the rolling part 41 can at least adopt a top bead.

[0063] Optionally, as shown in the figures, Figure 2 and Figure 3 The contact surface of the slide plate 21 contacting the spherical structure is configured as a curved surface matching the spherical structure. As an example, the slide plate 21 is provided with a rolling groove 211 on the inner wall of the first groove body 221, and the surface of the rolling groove 211 is configured as the aforementioned curved surface, and the length direction of the rolling groove 211 is consistent with the first movement direction.

[0064] It should be understood that the stabilizing structure 4 can be mounted on the inner wall of the first groove body 221, and of course can also be mounted on the rolling groove 211, as long as the rolling part 41 can contact the rolling groove 211 of the slide plate 21 or the inner wall of the first groove body 221 to improve the stability when the slide plate 21 and the base 22 relatively displace, that is, it conforms to the inventive concept of the present application, and the present application does not limit the mounting position of the stabilizing structure 4.

[0065] Optionally, as shown in the figures, Figure 2 , Figure 3 , Figure 7As shown, when the rolling part 41 is in contact with the rolling groove 211 and is extruded, the rolling part 41 will be compressed accordingly, and at the same time, the rolling part 41 will also move to one end of the first elastic part 42, which can also be understood as recessing to the inside of the opening end of the bushing 43, while the first elastic part 42 continues to provide an elastic force perpendicular to the movement direction to the rolling part 41, so that the rolling part 41 can form a close fit with the curved surface of the rolling groove 211, so as to compensate for the possible gap between the rolling groove 211 and the rolling part 41, and further ensure the stability of the handle 3 in the horizontal position or during rotation.

[0066] Alternatively, the rolling part 41 can also be configured in other possible shapes, such as a cylindrical structure, etc. The axis of the cylindrical structure can be perpendicular to the first movement direction, so that the cylindrical structure can roll along the first movement direction. The first elastic part 42 can be configured as a first spring, which at least provides a radial force to the cylindrical structure. The periphery of the first spring is further sleeved with a bushing for containing the first spring and mounting the cylindrical structure, and the bushing can be embedded on the inner wall of the first groove body 221 in a fixed manner. As an example, the two top surfaces of the cylindrical structure are respectively provided with connecting ends, and the bushing is correspondingly provided with mounting holes or mounting openings for mounting the connecting ends, and the connecting ends can move in a small range in the mounting holes or mounting openings, so as to automatically adjust the possible gap between the cylindrical structure and the sliding plate under the action of the first spring, and further make the handle not easy to shake. The contact surface of the sliding plate 21 in contact with the cylindrical structure can be configured as a plane matched with the cylindrical structure.

[0067] Alternatively, as shown in Figure 2 and Figure 3 The damping structure is further configured between the sliding plate 21 and the base 22, and the damping structure includes a second elastic part 5, which respectively abuts against the sliding plate 21 and the base 22, and provides an elastic force in the first movement direction to abut against the sliding plate 21, and further abut against the turning plate 1.

[0068] In the case that the lock has been installed, the handle 3 is in the daily use state, and the handle 3 is not subjected to the external force from the user, the handle 3 can be kept horizontal, at this time, the second elastic part 5 is squeezed by the action force from the slide plate 21 and the base 22 respectively, but the squeezing degree is relatively small. When the user wants to open the door, he / she will press down the handle 3, drive the rotation plate 1 to rotate, so that the partial initial abutting surface 1-1 abuts against the slide plate 21, and push the slide plate 21 to slide downward relative to the base 22, so that the action force on both ends of the second elastic part 5 becomes larger, that is, the squeezing degree of the second elastic part 5 becomes larger. At this time, the user can also feel the rebound force from the handle. When the user continues to press down the handle, the slide plate 21 will be limited by the limiting part 7 and cannot continue to rotate the handle 3. At this time, the rotation angle of the handle 3 is generally less than 90 degrees compared with the horizontal state, and exemplarily can be 60 degrees or other possible angles. When the user releases the handle 3, the second elastic part 5 provides the rebound force to push the slide plate 21 upward, the slide plate 21 pushes the rotation plate 1 upward, and then drives the handle 3 connected with the rotation plate 1 to recover to the horizontal position.

[0069] When the handle 3 needs to be reversed, the limiting part 7 can be removed, the handle 3 is rotated downward, the rotation plate 1 drives the slide plate 21 to slide downward, and the second elastic part 5 is continuously squeezed. When the handle 3 is rotated more than 90 degrees, the second elastic part 5 is gradually released from the limit state to enable the handle 3 to be rotated to the position of 180 degrees, and then the limiting part 7 is installed back, that is, the rapid reversing of the handle 3 is completed.

[0070] It should be understood that the setting of the damping structure not only helps to realize the automatic recovery in the use process of the handle 3, but also helps to solve the shaking problem of the handle 3 in various cases, at least including: when the handle 3 is not reversed and is in the horizontal position, the second elastic part 5 can continuously provide the relatively small elastic action force for the slide plate 21 to abut against the rotation plate 1, thereby stabilizing the handle 3 and effectively eliminating the shaking of the handle 3 in the horizontal position; and when the handle 3 is reversed, the damping structure can ensure the stability of the rotation plate 1 driven by the handle 3 when the slide plate 21 is displaced relative to the base 22, thereby solving the problem that the handle 3 is prone to shaking during the reversing process.

[0071] Optionally, as Figure 3 , Figure 5 , Figure 6As shown, the second elastic part 5 is configured as a second spring with the length direction consistent with the first movement direction, and the sliding plate 21 is further provided with a receiving cavity 212 adapted to accommodate the second spring. The second spring extends from the side of the sliding plate 21 facing the steering plate 1 (i.e. the side abutting against the steering plate 1) to the second side of the sliding plate 21 (i.e. the other side opposite to the first side) and reaches the base 22. For the convenience of description, the direction is also referred to as the longitudinal direction of the sliding plate 21 in the present application. That is, the second spring extends from the direction facing the steering plate 1 to the longitudinal direction of the sliding plate 21 and reaches the base. It should be understood that the length direction of the second elastic part 5 described above can exemplarily be the a direction as shown, or the direction opposite to the a direction, which is not limited herein. Figure 2 As shown, the second elastic part 5 is configured as a second spring with the length direction consistent with the first movement direction, and the sliding plate 21 is further provided with a receiving cavity 212 adapted to accommodate the second spring. The second spring extends from the side of the sliding plate 21 facing the steering plate 1 (i.e. the side abutting against the steering plate 1) to the second side of the sliding plate 21 (i.e. the other side opposite to the first side) and reaches the base 22. For the convenience of description, the direction is also referred to as the longitudinal direction of the sliding plate 21 in the present application. That is, the second spring extends from the direction facing the steering plate 1 to the longitudinal direction of the sliding plate 21 and reaches the base. It should be understood that the length direction of the second elastic part 5 described above can exemplarily be the a direction as shown, or the direction opposite to the a direction, which is not limited herein. Figure 3 、 Figure 5 and Figure 8 As shown, the base 22 and the sliding plate 21 are further provided with a relief structure, which at least includes an abutting part 6 arranged on the base 22 and abutting against the second spring; wherein,

[0072] The abutting part 6 has an abutting surface abutting against the second spring, and in the case that the abutting surface is a circular surface, the diameter of the circular surface is not less than the outer diameter of the second spring. It should be understood that the relief structure can be any structure capable of playing the same role as the abutting part 6. When the handle 3 is in the normal use state or in the process of reversing, the sliding plate 21 can slide in the first movement direction, and the relief structure can significantly improve the smoothness of the sliding plate 21 sliding on the base 22 in both directions. Exemplarily, the relief structure can be a semi-cylindrical shape or a cuboid shape to adapt to the receiving cavities 212 of different structures, and the specific implementation of the relief structure is not limited herein.

[0073] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The handle reversing mechanism further includes a limiting part 7. In the case that the handle 3 is in the use state, the limiting part 7 can limit the maximum stroke of the sliding plate 21 in the first movement direction. It can be understood that the limiting part 7 also limits the maximum rotation angle of the handle 3 in the use state.

[0074] Optionally, the limiting part 7 can be detachably connected with some structure in the lock, such as a door lock panel 8 or the base 22, exemplarily by a fastening nut. When it is necessary to reverse the handle 3, the installer can detach the limiting part 7, thereby removing the stroke limitation of the sliding plate 21 in the first movement direction, so that the handle 3 can be smoothly rotated by 180 degrees to realize the reversing. After the direction is adjusted, the installer can install the limiting part 7 in place, and the handle 3 returns to the normal use state.

[0075] Optionally, some structures in the lockset, such as the lower edge wall of the installation slot 81 of the door lock panel 8 for installing the handle reversing mechanism, can also realize the function of the limiting piece 7.
