Detailed Implementation

[0040] This utility model discloses an automatic lifting knob device and electronic device, which solves the technical problem that the lack of lifting function in existing control knobs prevents electronic devices from achieving a thin profile.

[0041] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 9 The present invention provides an automatic lifting knob device, including a base 1, a guide frame 2 movably disposed on the base 1, and a knob assembly 3 mounted on the guide frame 2;

[0043] A lifting transmission assembly is connected to the guide frame 2, and a lifting drive assembly is connected to the base 1. The lifting drive assembly is connected to the lifting transmission assembly to drive the guide frame 2 to rise or fall relative to the base 1.

[0044] In the automatic lifting knob device of this embodiment, when the user wants to use the knob assembly 3, the lifting drive assembly and the lifting transmission assembly can cooperate to drive the guide frame 2 to rise relative to the base 1, thereby raising the knob assembly 3 so that it can be easily operated by the user; when the user does not use the control knob, the knob assembly 3 can be controlled to fall relative to the base 1 so that it can be stored in the internal space of the electronic device, thereby reducing the thickness of the electronic device and effectively realizing the thinning of the electronic device.

[0045] Furthermore, the lifting transmission assembly in this embodiment has a variety of different structural forms. In the first specific embodiment, the lifting transmission assembly specifically includes a first lead screw 7 and a first transmission gear 6.

[0046] The top end of the first lead screw 7 is connected to the guide frame 2, and the middle part of the first transmission gear 6 is provided with a first threaded through hole. The first lead screw 7 is threadedly connected to the first threaded through hole.

[0047] The lifting drive assembly is connected to the first transmission gear 6 to drive the first transmission gear 6 to rotate, thereby driving the first lead screw 7 to drive the guide frame 2 to rise or fall relative to the base 1.

[0048] In the above specific embodiments, the lifting drive assembly specifically includes a first motor 4 and a second transmission gear 5;

[0049] The first motor 4 is mounted on the base 1, and the second transmission gear 5 is connected to the output end of the first motor 4. The second transmission gear 5 meshes with the first transmission gear 6.

[0050] It should be noted that, through the above design, the first motor 4 drives the second transmission gear 5 to rotate, and the second transmission gear 5 drives the first transmission gear 6 to rotate, thereby enabling the first lead screw 7 to achieve linear motion, which in turn drives the guide frame 2 and the knob assembly 3 to rise or fall relative to the base 1.

[0051] In the second specific embodiment, the lifting transmission assembly specifically includes a second lead screw 15 and a worm gear 14;

[0052] The top of the two lead screws is connected to the guide frame 2, and the middle part of the worm gear 14 is provided with a second threaded through hole. The second lead screw 15 is threadedly connected to the second threaded through hole.

[0053] The lifting drive assembly is connected to the worm gear 14 to drive the worm gear 14 to rotate, thereby driving the second lead screw 15 to drive the guide frame 2 to rise or fall relative to the base 1.

[0054] In the above specific embodiments, the lifting drive assembly specifically includes a second motor 12 and a worm gear 13;

[0055] The second motor 12 is mounted on the base 1, and the worm gear 13 is connected to the output end of the second motor 12. The worm gear 13 meshes with the worm wheel 14.

[0056] It should be noted that, through the above design, the second motor 12 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 14 to rotate, thereby enabling the second lead screw 15 to achieve linear motion, which in turn drives the guide frame 2 and the knob assembly 3 to rise or fall relative to the base 1.

[0057] In addition, it should be noted that, in order to save space, in this specific embodiment, the second motor 12 is fixed to the base 1 in a horizontal installation manner.

[0058] Furthermore, the automatic lifting knob device in this embodiment also includes a lifting control component;

[0059] The lifting control component is used to control the lifting position of the guide frame 2.

[0060] Specifically, the aforementioned lifting control assembly includes a control circuit board 9, a first Hall sensor 10, a second Hall sensor 11, and a magnet 8.

[0061] The control circuit board 9 is mounted on the base 1 and electrically connected to the lifting drive assembly. The first Hall sensor 10 and the second Hall sensor 11 are electrically connected to the control circuit board 9, and the first Hall sensor 10 is located above the second Hall sensor 11.

[0062] The magnet 8 is connected to the guide frame 2.

[0063] It should be noted that the specific working principle of the above-mentioned lifting control component is as follows:

[0064] When the guide frame 2 is driven to rise to the first preset position, the magnet 8 enters the sensing range of the first Hall sensor 10, and the lifting drive assembly stops driving the guide frame 2 to rise.

[0065] When the guide frame 2 is driven to descend to the second preset position, the magnet 8 enters the sensing range of the second Hall sensor 11, and the lifting drive assembly stops driving the guide frame 2 to descend.

[0066] In addition, in this embodiment, the first preset position is specifically the extreme position of the guide frame 2 and the knob assembly 3 when they rise, and the second preset position is specifically the extreme position of the guide frame 2 and the knob assembly 3 when they fall.

[0067] It should be further noted that the control circuit board 9 in this embodiment is prior art. As those skilled in the art will understand, the control circuit board 9 includes control components, such as control chips, etc., which will not be described in detail here.

[0068] Furthermore, in this embodiment, the base 1 is provided with a guide groove, and the guide frame 2 is movably inserted into the guide groove.

[0069] It should be noted that the above design makes the guide frame 2 more stable and smooth during the lifting process.

[0070] Furthermore, in this embodiment, the knob assembly 3 is engaged or fixed to the guide frame 2 by screws.

[0071] It should be noted that the knob assembly 3 in this embodiment is specifically in the prior art, and will not be described in detail here. Furthermore, the above-mentioned screw fixing and snap-fit ​​fixing methods make the knob assembly 3 easier to install.

[0072] Please see Figures 1 to 9 The present invention provides an electronic device including the above-mentioned automatic lifting knob device.

[0073] Specifically, the electronic device in this embodiment has a device housing. The automatic lifting knob device in this embodiment is installed on the device housing. When the knob assembly 3 is driven to rise relative to the base 1, the knob assembly 3 is exposed outside the device housing for user use. When the knob assembly 3 is driven to fall relative to the base 1, the knob assembly 3 is stored in the internal space of the device housing to reduce the thickness of the electronic device and effectively achieve the thinning of the electronic device.

[0074] The above provides a detailed description of an automatic lifting knob device and electronic device provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
