Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

[0018] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0019] This application provides a touch knob that is in contact with a touch display screen and is used to perform touch operations on the touch display screen to trigger the touch display screen to perform corresponding actions.

[0020] Figure 1 This is a schematic diagram of a touch knob 01 provided in an embodiment of this application. Figure 1As shown, the touch knob 01 includes a conductive housing 10, a conductive movable rod 20, and an inner rotating assembly 30. The housing 10 is in contact with the inner rotating assembly 30 and the two are rotatably connected, meaning that when the housing 10 rotates, it can drive the inner rotating assembly 30 to rotate. The movable rod 20 is connected to the inner rotating assembly 30, and when the inner rotating assembly 30 rotates, it drives the movable rod 20 to rotate. The housing 10 includes a contact portion 11, and the surface of the contact portion 11 facing the movable rod 20 includes a plurality of alternately distributed protrusions 111 and recesses 112. The protrusions 111 are protrusions on the surface of the contact portion 11 facing the direction of the movable rod 20, and the recesses 112 are recesses on the surface of the contact portion 11 away from the direction of the movable rod 20. When the movable rod 20 rotates, it alternately contacts the protrusions 111 and the recesses 112. It should be noted that, in order to clearly illustrate the components obscured by the housing 10, Figure 1 The left image in the figure shows the shell 10 in perspective.

[0021] Figure 2 This is a schematic diagram illustrating the connection between the touch knob 01 and the touch display screen. For clarity, the diagram is... Figure 2 A simplified illustration is provided for a portion of the structure of the touch-sensitive knob 01. Please refer to the provided text. Figure 3 The movable lever 20 includes a first end 21 and a second end 22 opposite to each other. The first end 21 can contact the contact portion 11 of the housing 10. When the touch knob 01 contacts the touch display screen, the second end 22 is located on the side of the first end 21 facing the touch display screen.

[0022] like Figure 2 As shown, during the rotation of the housing 10 of the touch knob 01, the inner rotating assembly 30 causes the first end 21 of the movable rod 20 to change from contacting the recessed portion 112 of the contact portion 11 to contacting the protruding portion 111. This causes the movable rod 20 to move towards the touch display screen 02, and the second end 22 of the movable rod 20 then contacts the touch display screen 02. Since both the housing 10 and the movable rod 20 are conductive, and the human body is also conductive, when the second end 22 of the movable rod 20 contacts the touch display screen 02, the human body changes the capacitance signal of the touch display screen 02 through the housing 10 and the movable rod 20, thereby achieving the touch effect.

[0023] like Figure 2 As shown, during the rotation of the housing 10 of the touch knob 01, when the first end 21 of the movable rod 20 changes from contacting the protrusion 111 of the contact portion 11 to contacting the recess 112 through the inner rotation assembly 30, the movable rod 20 moves away from the touch display screen 02, and the second end 22 of the movable rod 20 disconnects from the touch display screen 02, that is, the touch action of the touch knob 01 on the touch display screen 02 is interrupted or ended.

[0024] This application provides a simple touch knob 01, which is easier to implement and lower in cost. Furthermore, in the touch knob 01 provided by this application, the movable lever 20 rotates with the housing 10, and the movable lever 20 can contact different positions on the touch display screen 02, making it easy to distinguish the rotation direction and target touch position of the touch knob 01. Moreover, compared to touch knobs 01 in the prior art, the movable lever 20 in the touch knob 01 provided by this application rotates with the housing 10, and when the housing 10 rotates by the same angle, the touch knob 01 of this application generates more touch signals on the touch display panel, making the touch more sensitive.

[0025] Figure 3 This is a schematic diagram of a touch-sensitive knob provided in an embodiment of this application. In one embodiment of this application, combined with... Figure 1 and Figure 3 The touch knob 01 also includes a base 40, which and the housing 10 can form a cavity to accommodate the inner rotating component 30 and the movable rod 20 to protect these structures, and the inner rotating component 30 can be connected to the base 40 and / or the housing 10. Figure 4 This is a schematic diagram of the base of the touch knob 01 provided in the embodiments of this application, as shown below. Figure 4 As shown, the side of the base 40 facing the rotating component may include a fixed shaft 40a, which can be used to fix the inner rotating component 30. Of course, this fixation cannot restrict the inner rotating component 30 from rotating in response to the rotation of the housing 10.

[0026] Furthermore, the base 40 of the touch knob 01 can be a component of the touch knob 01 that is connected to the touch display screen 02 via a connecting structure. Therefore, the base 40 should not obstruct the contact between the second end 22 of the movable lever 20 and the touch display screen 02. Figure 3 As shown, the base 40 includes a first component 41 and a second component 42. The first component 41 has a ring-shaped structure and surrounds the second component 42. A gap 400 surrounding the second component 42 is included between the first component 41 and the second component 42. Figure 2 As shown, the movable rod 20 includes a main body 23 and a second end 22. The second end 22 is located on the side of the main body 23 away from the contact portion 11, and is combined with... Figure 2 and Figure 3Along the arrangement direction of the movable rod 20 and the contact portion 11, the projection of the second end 22 is located within the gap 400. Therefore, when the touch knob 01 is connected to the touch display screen 02, the second end 22 of the movable rod 20 can protrude through the gap 400 between the first component 41 and the second component 42 and make contact with the touch display screen 02. The base 40 can be an insulating structure. Furthermore, the first component 41 and the second component 42 can be connected to the housing 10 respectively; for example, both the contact portion 11 and the second component 42 are engaged with the housing 10.

[0027] The following describes one specific implementation of the inner spin component 30. Figure 4 This is a schematic diagram of a touch-sensitive knob provided in an embodiment of this application. For clarity, Figure 4 The diagram illustrates the inner rotating assembly 30 and the housing 10, but the base 40 is omitted. (Combined) Figure 1 and Figure 4 The inner rotating assembly 30 includes a connecting gear 31 and an inner gear 32. The inner side of the housing 10 includes multiple teeth (hereinafter referred to as housing teeth 12 for ease of description). The connecting gear 31 meshes between the inner gear 32 and the housing 10. Specifically, the inner side of the sidewall of the housing 10 includes multiple housing teeth 12, and the connecting gear 31 meshes between the teeth of the inner gear 32 and the housing teeth 12. When the housing 10 rotates, the housing teeth 12 drive the connecting gear 31 to rotate, and the connecting gear 31 drives the inner gear 32 to rotate. Therefore, the inner rotating assembly 30 can rotate in response to the rotation of the housing 10.

[0028] In one implementation, the movable rod 20 can be connected to the internal gear 32. When the connecting gear 31 rotates in response to the rotation of the housing 10 and drives the internal gear 32 to rotate, the movable rod 20 can also rotate.

[0029] In one implementation, the connecting gear 31 can be a planetary gear, and its size can be significantly smaller than that of the internal gear 32, which is beneficial for achieving a lightweight design of the touch knob 01. To drive the larger internal gear 32, multiple connecting gears 31 can be used, with the multiple connecting gears 31 working together to drive the internal gear 32. For example, as... Figure 4 As shown, three connecting gears 31 can be set together to drive the internal gear 32 to rotate, thereby reducing the wear of each connecting gear 31. Furthermore, the three connecting gears 31 can be evenly distributed to effectively limit the position of the internal gear 32 within the rotation surface of the touch knob 01, thus reducing the risk of displacement of the internal gear 32.

[0030] In addition, combined Figure 1 and Figure 1 , Figure 4The second component 42 of the base 40 may include a fixed shaft 40a on the side facing the inward rotating assembly 30, that is, the second component 42 includes a fixed shaft 40a facing the connecting gear 31. The connecting gear 31 may include a hole 310, and the hole 310 may extend through the thickness direction of the connecting gear 31. The fixed shaft 40a of the second component 42 is at least partially located within the hole 310 of the connecting gear 31, that is, the hole 310 of the connecting gear 31 can be nested on the fixed shaft 40a. When the housing 10 rotates, the housing teeth 12 can drive the connecting gear 31 to rotate around the fixed shaft 40a. The connecting gear 31 can be fixed to the base 40 by the relatively small fixed shaft 40a, which is easy to implement and facilitates the lightweight design of the touch knob 01. It should be noted that the fixed shaft 40a may also be provided on the connecting gear 31 and the hole 310 may be provided on the second component 42, which will not be described in detail here.

[0031] The internal gear 32 may not be fixedly connected to the housing 10 or the base 40, allowing the internal gear 32 to drive the movable rod 20 to rotate within a large range. To ensure the stability of the internal gear 32, the housing 10 or the base 40 can still be used to position the internal gear 32. In one implementation, such as... Figure 3 As shown, the inner wall of the first component 41 of the base 40 may include a groove 40b, which, in conjunction with... Figure 1 and Figure 3 The edge portion of the internal gear 32 is embedded in the groove 40b. Therefore, when the internal gear 32 rotates, the base 40 does not restrict the rotation direction of the internal gear 32. However, the groove 40b of the base 40 can prevent the internal gear 32 from shifting in the thickness direction of the touch knob 01, and can also prevent the internal gear 32 from shifting within the rotation surface of the touch knob 01. It should be noted that the groove 40b containing the edge portion of the internal gear 32 can be located not only on the inner side wall of the base 40, but also on the inner side wall of the housing 10; further details will not be elaborated here.

[0032] Figure 5 This is an exploded view of a portion of the structure of the touch knob provided in the embodiments of this application, as shown below. Figure 5 As shown, in one embodiment of this application, the inner rotating component 30 includes an opening 300. When the touch knob 01 contacts the touch display screen 02, the through direction of the opening 300 in the inner rotating component 30 is consistent with the arrangement direction of the touch knob 01 and the touch display screen 02. Combined with... Figure 5 and Figure 1 , Figure 4When the movable lever 20 passes through the opening 300 of the inner rotating assembly 30 and alternately contacts the protrusion 111 and the recess 112, the movable lever 20 is restricted by the opening 300 to move along the through direction of the opening 300, that is, along the arrangement direction of the touch knob 01 and the touch display screen 02, so that the movable lever 20 can make and break contact with the touch display screen 02.

[0033] This application embodiment provides a connection method between an inner rotating component 30 and a movable rod 20. By setting the movable rod 20 to pass through an opening 300, the connection position between the movable rod 20 and the inner rotating component 30 is determined at the position of the opening 300. The movable rod 20 rotates with the rotation of the inner rotating component 30, and can thus respond to the user's rotation degree of the housing 10. When the movable rod 20 rotates to the corresponding position, it triggers the corresponding function. In addition, after passing through the opening 300, the movable rod 20 can also move along the through direction of the opening 300. Therefore, at least the second end 22 of the movable rod 20 can be regarded as a free end. In response to the first end 21 of the movable rod 20 contacting the recess 112 of the contact portion 11, the second end 22 of the movable rod 20 disconnects from the touch display screen 02; in response to the second end 22 of the movable rod 20 contacting the protrusion 111 of the contact portion 11, the second end 22 of the movable rod 20 achieves contact with the touch display screen 02. In the solution provided in this embodiment, the movable rod 20 is connected to the inner rotating component 30 through the opening 300. This allows the movable rod 20 to rotate and move as the inner rotating component 30 rotates, while simultaneously allowing the movable rod 20 to move along the through direction of the opening 300, so that the second end 22 can act as a free end and either contact or not contact the touch display screen 02. The way the opening 300 restricts the connection of the movable rod 20 ensures a stable connection between the movable rod 20 and the inner rotating component 30; furthermore, the structure is simple and easy to implement.

[0034] In this embodiment, the movable lever 20 has a retractable characteristic relative to the bottom of the touch knob 01. For example, the second end 22 of the movable lever 20 can protrude beyond the bottom of the touch knob 01 to make contact with the touch display screen 02, and can retract to the inside of the bottom of the touch knob 01 to disconnect from the touch display screen 02; or, the second end 22 of the movable lever 20 can protrude a longer length beyond the bottom of the touch knob 01 to make contact with the touch display screen 02, and can protrude a shorter length beyond the bottom of the touch knob 01 to disconnect from the touch display screen 02. This embodiment also provides a method for making the movable lever 20 retractable relative to the bottom of the touch knob 01.

[0035] Figure 6 This is a schematic diagram of a portion of the structure of a touch-sensitive knob provided in an embodiment of this application. Figure 6This diagram illustrates a connection method between the movable rod 20 and the inner rotating assembly 30, specifically the connection method of the opening 300 included in the movable rod 20 and the inner rotating assembly 30, in conjunction with... Figure 5 and Figure 6 The touch knob 01 also includes a spring 50, and the movable lever 20 includes a limiting structure 24 located on the side of the opening 300 facing the contact portion 11 of the housing 10. One end of the spring 50 is in contact with the limiting structure 24 and the other end is in contact with the inner rotating assembly 30. The limiting structure 24 restricts the spring 50 between the first end 21 of the movable lever 20 and the inner rotating assembly 30. Wherein, the extension direction of the spring 50 is parallel to the penetration direction of the opening 300, thus the spring 50 can control the movable lever 20 to move along the penetration direction of the opening 300. Figure 7 A schematic diagram showing the connection between the movable rod and the contact part, such as... Figure 7 As described above, when the first end 21 of the movable rod 20 contacts the protrusion 111 of the contact portion 11, the movable rod 20 moves along the through direction of the opening 300 and the bottom of the touch control knob 01. Correspondingly, the limiting structure 24 moves toward the inward rotating assembly 30, and the spring 50 is compressed by the limiting structure 24. When the housing 10 continues to rotate, the first end 21 of the movable rod 20 leaves the position of the protrusion 111 and rotates toward the position of the recess 112. During this process, the elastic force of the spring 50 causes the limiting structure 24 to move away from the inward rotating assembly 30, and causes the first end 21 of the movable rod 20 to contact the recess 112.

[0036] In one implementation, such as Figure 2 and Figure 7 As shown, the movable rod 20 also includes a main body 23. A limiting structure 24 is located on the side of the main body 23 away from the opening 300, and the limiting structure 24 protrudes from the main body 23 in at least a first direction, perpendicular to the through direction of the opening 300. That is, in at least one direction perpendicular to the extension and contraction of the spring, the limiting structure 24 of the movable rod 20 protrudes from the main body 23 to connect one end of the spring member 50 to a defined position on the movable rod 20. The spring member 50 is located on the side of the limiting structure 24 facing the main body 23 and is sleeved on the outside of the main body 23; that is, the spring member 50 is nested on the main body 23 of the movable rod 20, and one end of the spring member 50 contacts the limiting structure 24 of the movable rod 20.

[0037] In one embodiment of this application, such as Figure 7As shown, the first end portion 21 is located on the side of the main body 23 facing the contact portion 11, and the first end portion 21 has a hemispherical structure. Setting the first end portion 21 as a hemispherical structure can reduce wear between the first end portion 21 and the protrusions 111 and recesses 112 of the contact portion 11 during alternating contact, and can achieve better electrical contact by better contacting the protrusions 111 and recesses 112. The first end portion 21 and the main body 23 can be an integral structure, and both can belong to different parts of the same metal conductive component.

[0038] In one embodiment of this application, the second end portion 22 is located on the side of the main body portion 23 away from the contact portion 11, and the second end portion 22 is the end portion used to contact the touch display screen 02. To ensure that the second end portion 22 has sufficient contact area with the touch display screen 02 so that changes in the touch signal can be easily identified, the surface of the second end portion 22 facing away from the main body portion 23 is a planar structure.

[0039] In one implementation, such as Figure 7 As shown, the second end portion 22 can be an integral structure with the main body portion 23, and the two can also belong to different parts of the same metal conductive component. In addition, the second end portion 22 can be a cross-section of the main body portion 23.

[0040] In one implementation, such as Figure 8 As shown, Figure 8 This is a schematic diagram of the movable lever 20 in the touch knob 01 provided in the embodiments of this application, as shown below. Figure 8 As shown, the second end portion 22 can be made of a different material than the main body portion 23, and the hardness of the second end portion 22 is less than that of the main body portion 23, in order to reduce the risk of damaging the touch display screen 02 when the second end portion 22 comes into contact with the touch display screen 02. The main body portion 23 can be a metal structure, and the second end portion 22 can be a conductive pad 220, with the two connected by conductive adhesive or other conductive connection structures.

[0041] Figure 9 This is a schematic diagram of a display device provided in an embodiment of this application, such as... Figure 9 As shown in the illustration, this application also provides a display device, which may include a touch screen 02 and a touch knob 01 provided in any of the above embodiments. The touch knob 01 may be fixedly connected to the touch screen 02. When the user rotates the touch knob 01, they can perform touch operations on the touch screen 02. The display device provided in this application can be a vehicle display control panel, a display control board for smart home appliances, a display control screen for industrial equipment, etc.

[0042] Figure 10 This is a cross-sectional schematic diagram of a display device provided in an embodiment of this application. Figure 10As shown, the display device also includes an adhesive 03, which securely connects the touch knob 01 and the touch display screen 02. Specifically, when the base 40 of the touch knob 01 includes a first component 41 and a second component 42, the adhesive 03 is adhered between the first component 41 and the touch display screen 02, and / or, the adhesive 03 is adhered between the second component 42 and the touch display screen 02. Furthermore, the adhesive 03 should avoid the gap 400 between the first component 41 and the second component 42 so that the movable rod 20 can contact the touch display screen 02. The connection method between the touch knob 01 and the touch display screen 02 provided in the embodiments of this application is easy to implement and makes the touch knob 01 easy to replace. By using an adhesive connection, the display area of ​​the touch display screen 02 does not need to be designed to avoid the connection structure that connects the touch knob 01 and the touch display screen 02, ensuring the integrity of the touch display screen 02 and reducing manufacturing difficulty.

[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 substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or combinations can be made to some or all of the technical features.
