Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a handle transmission structure. Background Art

[0002] The handle transmission structure is an intermediate transmission device used to connect components such as a handle and a door / window locking structure. Its main function is to convert the rotational movement of the handle into a linear movement or a specific action of a door / window lock or other related components, so as to achieve functions such as opening, closing, and locking of the door and window.

[0003] For example, a handle and door / window system with rotational sound feedback disclosed in Chinese Utility Model No. CN220415057U generates clear sound feedback through the grooves arranged at intervals and the beads under the action of an elastic member, similar to a ticking sound feedback. It can not only obtain a better rotational experience, but also the sound feedback generated by a pure mechanical structure has a small volume, effectively reducing the impact on other neighbors. However, such a structure still has the following significant defects:

[0004] The prior art only relies on a single layer of sound feedback components for feedback, and the feedback information is single, unable to meet diverse prompting requirements. Moreover, at the critical node when the door and window is nearly fully opened or closed, it cannot effectively prompt, easily causing the user to overexert due to ignorance, thereby damaging the handle transmission structure and affecting its service life and normal use.

[0054] Next, in conjunction with the accompanying drawings, the handle drive structure provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0055] Embodiment 1:

[0056] As Figures 1 to 5 shown, the embodiment of the present application provides a handle drive structure, including a mounting seat 1 and a rotating core 2; further including a rotating member 3 rotatably connected to the mounting seat 1; a receiving hole 4 provided in the mounting seat 1; and an elastic member 5 provided on the receiving hole 4.

[0057] Further, the rotating member 3 includes a feedback seat 31 rotatably connected to the mounting seat 1; a positioning seat 32 fixedly connected to the feedback seat 31; and a transmission gear 33 fixedly connected to one end of the positioning seat 32 facing away from the feedback seat 31.

[0058] Further, the rotating member 3 further includes a first groove 34 provided on the feedback seat 31; a second groove 35 provided on the positioning seat 32; wherein, four of the second grooves 35 are equidistantly provided on the positioning seat 32.

[0059] Further, the receiving hole 4 includes a first receiving hole 41 in the same plane as the feedback seat 31; and a second receiving hole 42 in the same plane as the positioning seat 32.

[0060] Further, the elastic member 5 includes a first spring 51, one end of which is fixedly connected in the first receiving hole 41; and a steel ball 52 fixedly connected to the other end of the first spring 51; wherein, the steel ball 52 abuts against the first groove 34.

[0061] Further, the elastic member 5 further includes a second spring 53, one end of which is fixedly connected within the second receiving hole 42; and a steel ball 54, which is fixedly connected to the other end of the second spring 53; wherein, the steel ball 54 abuts against the second groove 35.

[0062] Further, the size of the second spring 53 is larger than that of the first spring 51, and the size of the steel ball 54 is larger than that of the steel ball 52.

[0063] In this embodiment of the present application, due to the adoption of the above structure, an elastic member 5 is provided within the first receiving hole 41, and the elastic member 5 abuts against the feedback seat 31, which can be used to increase the rotational resistance of the feedback seat 31. After appropriately increasing the rotational resistance of the feedback seat 31, the user will feel a certain feedback force during the rotation process, thereby enhancing the user experience;

[0064] One end of the first spring 51 is fixedly connected to the bottom surface of the inner cavity of the first receiving hole 41, and the other end is fixedly connected to the steel ball 52. The first spring 51 pushes the steel ball 52 into the first groove 34. The steel ball 52 will rotate when the feedback seat 31 rotates, and a sliding friction is generated between the steel ball 52, the feedback seat 31, and the first groove 34, which serves to increase the rotational resistance of the feedback seat 31. To make the force on the feedback seat 31 balanced, a pair of the first spring 51 and the steel ball 52 are symmetrically arranged on both sides of the feedback seat 31;

[0065] An elastic member 5 is also provided within the second receiving hole 42, and the elastic member 5 abuts against the positioning seat 32, which can further increase the rotational resistance when the door or window is fully closed or fully opened, serving as a reminder;

[0066] One end of the second spring 53 is fixedly connected to the bottom surface of the inner cavity of the second receiving hole, and the other end is fixedly connected to the steel ball 54. Four second grooves 35 are equidistantly arranged on the positioning seat 32. The second spring 53 pushes the steel ball 54 into the second groove 35. Whenever the positioning seat 32 rotates 90 degrees, the second spring 53 will push the steel ball 54 back into the second groove 35, thereby further enhancing the rotational resistance and serving as a reminder. To make the force on the positioning seat 32 balanced, a pair of the second spring 53 and the steel ball are symmetrically arranged on both sides of the positioning seat 32;

[0067] Compared with the first spring 51, the second spring 53 has a larger size, and thus has stronger elasticity. Similarly, the size of the steel ball 54 is larger than that of the steel ball 52, such that whenever the rotating member rotates 90 degrees, the elastic member 5 will provide a greater resistance.

[0068] Embodiment 2:

[0069] Such as Figure 6As shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, an installation groove 6 is provided on the feedback seat 31; wherein, the rotating core 2 is inserted into the installation groove 6, and a pair of buffer members 7 are provided between the rotating core 2 and the installation groove 6.

[0070] Furthermore, each of the pair of buffer members 7 includes a movable groove 71, which is provided at one end of the feedback seat 31 facing away from the positioning seat 32; and a spring piece 72, which is provided in the movable groove 71; wherein, the movable groove 71 communicates with the installation groove 6.

[0071] Furthermore, the spring piece 72 includes a fixed portion 721, which is fixedly connected to the movable groove 71; and a movable portion 722, which abuts against the rotating core 2.

[0072] In this embodiment of the present application, due to the adoption of the above structure, when the rotating core 2 rotates, the rotating core 2 presses the movable portion 722 to deform it in the movable groove 71, and the movable groove 71 is used to provide a space for the deformation of the movable portion 722. At this time, the movable portion 722 will transmit the driving force to the feedback seat 31 to make it rotate. During the transmission process, a buffer space is left between the rotating core 2 and the feedback seat 31, so that when the user applies excessive force, the impact and wear between the rotating core 2 and the feedback seat 31 can be reduced, thereby significantly improving its overall durability and service life.
