For example, the knob control device can control functions such as the volume and temperature of the equipment. In order to improve the performance of the knob control device, the pressing function has been added to the knob control devices on the market. Adding the pressing function to the knob control device has undoubtedly become more and more mainstream.

[0003] In the related art, the knob control device includes a knob body, a hollow encoder, and an elastic member. The elastic member is sleeved on the outer ring of the hollow encoder, and the knob body is connected to the hollow encoder through the elastic member. At this time, when the knob body is rotated, the knob body can drive the outer ring of the hollow encoder to rotate through the elastic member, so as to realize the rotation function; in addition, the knob body is elastically connected to the hollow encoder through the elastic member, so the pressing operation of the knob body can be realized, and thus the pressing function of the knob control device can be realized. Therefore, the hollow encoder combined with the elastic member can realize the superposition of the pressing action and the rotation action.

[0004] However, as the number of times the knob control device is used increases, the mechanical properties of the elastic member gradually decrease, resulting in a worse and worse reset effect of the elastic member, and further affecting the pressing function of the knob control device. Therefore, the reliability of the knob control device in the related art is poor. Summary of the Utility Model

[0009] The knob ring can rotate relative to the knob bracket about the central axis of the bearing; the knob bracket can be switched between a pressing position and a triggering position relative to the mounting housing along the axis direction of the bearing, and the knob bracket can overcome the magnetic force between the first magnetic member and the second magnetic member to switch the knob bracket from the pressing position to the triggering position; the magnetic force between the first magnetic member and the second magnetic member can switch the knob bracket from the triggering position to the pressing position.

[0012] In the knob control device disclosed by the present utility model, when the knob bracket is pressed, the knob bracket can overcome the magnetic force between the first magnetic member and the second magnetic member to switch the knob bracket from the pressing position to the triggering position. When the pressing force on the knob bracket is removed, the magnetic force between the first magnetic member and the second magnetic member can switch the knob bracket from the triggering position to the pressing position. The technical solution disclosed in this application uses the magnetic force between the first magnetic member and the second magnetic member to reset the knob bracket after pressing.

Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The following will, with reference to the drawings, elaborate on the technical solutions disclosed in each embodiment of the present utility model in detail.

[0023] As Figures 1 to 9 shown, an embodiment of the present utility model discloses a knob control device 100, and the disclosed knob control device 100 includes a mounting housing 110, a bearing 120, a knob bracket 130 and a knob ring 140.

[0024] The installation housing 110 provides an installation basis for other components of the knob control device 100. The installation housing 110 is provided with a first magnetic member 151. The knob bracket 130 is provided with a second magnetic member 152. The knob bracket 130 and the installation housing 110 can be magnetically connected through the first magnetic member 151 and the second magnetic member 152. Optionally, the first magnetic member 151 and the second magnetic member 152 can be electromagnets or permanent magnets.

[0025] It can be understood here that the knob bracket 130 and the installation housing 110 are maintained in a relatively fixed position by the magnetic force between the first magnetic member 151 and the second magnetic member 152. For example, through the magnetic attraction force between the first magnetic member 151 and the second magnetic member 152, the knob bracket 130 and the installation housing 110 are attracted together. Or, through the magnetic repulsion force between the first magnetic member 151 and the second magnetic member 152, the knob bracket 130 is limited on the installation housing 110.

[0026] The inner ring 121 of the bearing 120 is fixedly connected to the knob bracket 130, and the knob ring 140 is fixedly sleeved on the outer ring 122 of the bearing 120. The knob ring 140 can rotate relative to the knob bracket 130 around the central axis of the bearing 120. Since the outer ring 122 and the inner ring 121 of the bearing 120 are in rolling fit through rolling elements, the outer ring 122 and the inner ring 121 can rotate relative to each other. Therefore, the knob ring 140 can rotate together with the outer ring 122 of the bearing 120, so that the knob ring 140 can rotate relative to the knob bracket 130. The rotation of the knob ring 140 relative to the knob bracket 130 can realize the rotation function of the knob control device 100.

[0027] The knob bracket 130 can be switched between a pressing position and a triggering position relative to the mounting housing 110 along the axial direction of the bearing 120. At this time, the knob bracket 130 can move along the axial direction of the bearing 120, so that the pressing function of the knob control device 100 can be realized. The knob bracket 130 can overcome the magnetic force between the first magnetic member 151 and the second magnetic member 152 to switch the knob bracket 130 from the pressing position to the triggering position. The magnetic force between the first magnetic member 151 and the second magnetic member 152 can switch the knob bracket 130 from the triggering position to the pressing position. The pressing position of the knob bracket 130 here refers to the position when no pressing force is applied to the knob bracket 130, and it can also be understood as the position when the knob bracket 130 does not trigger the corresponding pressing function. The initial position between the knob bracket 130 and the mounting housing 110 maintained by the first magnetic member 151 and the second magnetic member 152. At this time, the knob bracket 130 does not trigger the corresponding function. The triggering position refers to the relative position between the knob bracket 130 and the mounting housing 110 when a pressing force is applied to the knob bracket 130. It can also be understood that the knob bracket 130 triggers the corresponding pressing function. At this time, the knob bracket 130 triggers the corresponding function.

[0028] During the specific operation process, as Figure 3 shown, when only a rotational movement is applied to the knob ring 140, the knob ring 140 drives the outer ring 122 of the bearing 120 to rotate as a whole. Since the inner ring 121 and the outer ring 122 of the bearing 120 are connected by rolling elements, the friction between the inner ring 121 and the outer ring 122 of the bearing 120 is small, and the inner ring 121 of the bearing 120 will not rotate with the rotation of the outer ring 122. If the inner ring 121 of the bearing 120 is slightly rotated passively, the inner ring 121 of the bearing 120 is fixed to the knob bracket 130, and the knob bracket 130 is fixed to the mounting housing 110 by the acting force between the first magnetic member 151 and the second magnetic member 152. Therefore, it is very difficult for the inner ring 121 of the bearing 120 to rotate and shift, so that only the knob ring 140 can rotate. At this time, a corresponding triggering mechanism can be set on the device body of the device and the knob control device. When the knob rotates, the triggering mechanism is triggered to transmit a signal, so as to realize the rotation control function. The specific structure of the triggering mechanism is a well-known technology and is not limited in this article.

[0029] When a pressing force is applied to the knob ring 140 or the knob bracket 130, since the inner ring 121 and the outer ring 122 of the bearing 120 are fixed by the intermediate rolling elements and the cage, the entire bearing 120 will also move along with the movement of the outer ring 122 or the inner ring 121 of the bearing 120. Here, it is necessary to overcome the acting force between the first magnetic member 151 and the second magnetic member 152 in order to press and move the knob bracket 130, the knob ring 140, and the bearing 120 together. The moving directions of the knob bracket 130, the knob ring 140, and the bearing 120 are as Figure 3 shown by the vertically downward arrow in

[0030] until they are moved to the trigger position. When the pressing force applied to the knob ring 140 or the knob bracket 130 is removed, the acting force between the first magnetic member 151 and the second magnetic member 152 drives the knob bracket 130, the knob ring 140, and the bearing 120 to move back to their original positions. Here, it can be understood that the acting force between the first magnetic member 151 and the second magnetic member 152 drives the knob bracket 130, the knob ring 140, and the bearing 120 to move in the vertically upward direction, as Figure 3 shown by the vertically upward arrow in

[0031] until they are moved to the pressing position. Of course, when rotating the knob ring 140, a pressing force can also be applied to the knob ring 140 simultaneously, so as to perform a pressing operation on the knob control device 100. Therefore, the rotation and pressing operations of the knob control device 100 in this application can be carried out simultaneously. In one application environment, the rotation operation of the knob ring 140 can achieve the regulation of functions, such as the selection of temperature and volume, while the pressing operation of the knob ring 140 can achieve the confirmation of the current function. Of course, the rotation and pressing operations of the knob control device 100 can also correspond to different functions, which are not limited in this article.

[0032] In the embodiments disclosed in this application, the first magnetic member 151 and the second magnetic member 152 are used to reset the knob bracket 130 after pressing through the magnetic force. The magnetic force between the first magnetic member 151 and the second magnetic member 152 is relatively stable and has a longer service life compared with elastic members. Therefore, it has a better reset effect, and thus is not likely to affect the pressing function of the knob control device 100, so the reliability of the knob control device 100 is improved.

[0033] In addition, the knob ring 140 disclosed in this application realizes rotational movement through the bearing 120. Compared with a hollow encoder, the friction coefficient of the bearing 120 is smaller, so the rotation is smoother, thus improving the user experience. In addition, the bearing 120 can achieve stepless adjustment of the knob ring 140, so that the knob ring 140 has a better rotation effect.

[0034] In one solution, the magnetic poles of the opposite faces of the first magnetic member 151 and the second magnetic member 152 are the same, that is to say, the first magnetic member 151 and the second magnetic member 152 are in magnetic repulsion cooperation. At this time, the magnetic poles of the opposite faces of the first magnetic member 151 and the second magnetic member 152 can be N pole against N pole or S pole against S pole. The magnetic repulsive force between the first magnetic member 151 and the second magnetic member 152 causes the knob bracket 130 and the mounting housing 110 to be relatively suspended. Here, in order to ensure the stable suspension of the knob bracket 130 and the mounting housing 110, a guiding structure and a limiting structure can be provided on the mounting housing 110 to limit and guide the position of the knob bracket 130.

[0035] In the specific operation process, the user applies a pressing force to the knob ring 140 or the knob bracket 130, and the pressing force is greater than the magnetic repulsive force between the first magnetic member 151 and the second magnetic member 152, so that the knob bracket 130 is switched from the pressing position to the triggering position. When the acting force on the knob bracket 130 is removed, the magnetic repulsive force between the first magnetic member 151 and the second magnetic member 152 causes the first magnetic member 151 and the second magnetic member 152 to move away from each other, so that the knob bracket 130 is switched from the triggering position to the pressing position.

[0036] In another alternative embodiment, the mounting housing 110 may have a first surface 1101 and a second surface 1102 arranged opposite to each other. The mounting housing 110 may be provided with an opening 1103 that penetrates the first surface 1101 and the second surface 1102, and the above-mentioned first magnetic member 151 may be provided on the second surface 1102.

[0037] The knob bracket 130 may include a first bracket 131 and a second bracket 132. The first bracket 131 may be located on the side where the second surface 1102 of the mounting housing 110 is located. The second magnetic member 152 may be disposed on the first bracket 131. The first bracket 131 can be attracted to the second surface 1102 by the first magnetic member 151 and the second magnetic member 152. At this time, the magnetic poles of the surfaces of the opposite sides of the first magnetic member 151 and the second magnetic member 152 are opposite. At this time, the magnetic poles of the opposite faces of the first magnetic member 151 and the second magnetic member 152 can be N pole against S pole.

[0038] The first bracket 131 and the second bracket 132 can be communicated through the opening 1103. At this time, a part of the first bracket 131 can protrude through the opening 1103 to be connected to the second bracket 132 on the first surface 1101, or a part of the second bracket 132 can extend through the opening 1103 toward the side of the second surface 1102 to be connected to the first bracket 131. At least a part of the second bracket 132 and at least a part of the knob ring 140 protrude from the first surface 1101, and the second bracket 132 is fixedly connected to the inner ring 121 of the bearing 120. The first surface 1101 here can be understood as the outer surface or the surface on the side facing the user. The second surface 1102 can be understood as the inner surface or the surface on the side away from the user. At least a part of the second bracket 132 and at least a part of the knob ring 140 protruding from the first surface 1101 facilitate the user to press and turn the knob ring 140 or the second bracket 132.

[0039] During the specific operation process, when the pressing force applied by the user to the second bracket 132 or the knob ring 140 is greater than the magnetic attraction force between the first magnetic member 151 and the second magnetic member 152, the first bracket 131 drives the second magnetic member 152 to gradually move away from the first magnetic member 151. Therefore, the first bracket 131 moves away from the second surface 1102, so that the knob bracket 130 switches to the trigger position. When the pressing force on the second bracket 132 or the knob ring 140 is removed, the attraction force between the first magnetic member 151 and the second magnetic member 152 can re-attract the first bracket 131 to the mounting housing 110, so that the knob bracket 130 switches to the pressing position. In addition, the second surface 1102 here is also used to limit the first bracket 131 in the magnetic force direction of the first magnetic member 151 and the second magnetic member 152, so that the first bracket 131 can maintain its relative position unchanged when not subjected to the pressing force.

[0040] This solution can achieve the suction and cooperation between the knob bracket 130 and the mounting housing 110. Therefore, the suction and cooperation between the knob bracket 130 and the mounting housing 110 is not likely to cause the knob bracket 130 to shake relative to the mounting housing 110, thus improving the stability of the knob bracket 130 and the knob ring 140. In addition, the knob bracket 130 is divided into two parts. The first bracket 131 is used for magnetic suction cooperation with the mounting housing 110, while the second bracket 132 is used for connecting to the inner ring 121 of the bearing 120, so it is convenient for the assembly of the knob control device 100.

[0041] In another alternative embodiment, when the knob bracket 130 is in the pressed position, there is a first gap A between the knob ring 140 and the first surface 1101. The first gap A here can be understood as the reserved pressing movement distance of the knob ring 140. When the knob bracket 130 is in the triggered position, there is a second gap B between the knob ring 140 and the first surface 1101, and the distance of the first gap A is greater than the distance of the second gap B. At this time, when the knob bracket 130 is in the triggered position, there is a gap reserved between the knob ring 140 and the first surface 1101, thus avoiding the problem that the knob ring 140 directly abuts against the first surface 1101, which affects the difficult rotation of the knob ring 140 when pressed.

[0042] In the above solution, the mounting housing 110 can be a flat plate. At this time, the knob ring 140 and the first bracket 131 are respectively located on both sides of the flat plate, and the flat plate can be directly fixed to the device body of the device. Alternatively, the mounting housing 110 can be provided with a receiving cavity 1105. The knob ring 140 can be located outside the receiving cavity 1105, at least part of the first bracket 131 and the second magnetic member 152 can be installed in the receiving cavity 1105, and the above-mentioned opening 1103 is communicated with the receiving cavity 1105. The first surface 1101 can be the outer surface of the mounting housing 110, and the second surface 1102 can be the inner surface of the mounting housing 110, that is, the inner wall of the receiving cavity 1105.

[0043] In another alternative solution, the first bracket 131 can include a first support plate 1311, an extension protrusion 1312 and a first buckle 1313. The extension protrusion 1312 is provided with a first guiding portion 1312a. The first support plate 1311 can have a first area 1311a and a second area 1311b. The second area 1311b can be arranged to surround the first area 1311a. The extension protrusion 1312 and the first buckle 1313 can be arranged at intervals in the first area 1311a. The first area 1311a can be arranged opposite to the opening 1103, and the second magnetic member 152 can be arranged in the second area 1311b. Therefore, the first support plate 1311 is attracted to the second surface 1102 by the second magnetic member 152. At this time, since the first area 1311a is opposite to the opening 1103, the first area 1311a is exposed through the opening 1103. Therefore, the extension protrusion 1312 and the first buckle 1313 arranged on the first area 1311a can extend to the side where the first surface 1101 is located through the opening 1103.

[0044] The second bracket 132 may include a second support plate 1321 and an annular body portion 1322. The annular body portion 1322 may be disposed on a side of the second support plate 1321 facing the first bracket 131. A second buckle 1322a and a second guiding portion 1322b may be provided on an inner circumferential surface of the annular body portion 1322. The first buckle 1313 may be engaged with the second buckle 1322a in a snap-fit manner, and the first guiding portion 1312a may be guided and engaged with the second guiding portion 1322b along an axial direction of the opening 1103.

[0045] In a specific assembly process, first, the first bracket 131 is magnetically attracted to the second surface 1102. At this time, the extending protrusion 1312 and the first buckle 1313 may extend through the opening 1103 toward the side where the first surface 1101 is located. Then, the second bracket 132 is installed from one side of the first surface 1101. The second guiding portion 1322b on the second bracket 132 is aligned with the first guiding portion 1312a, and then the second bracket 132 is pushed to slide in a direction toward the first bracket 131. At this time, the first guiding portion 1312a and the second guiding portion 1322b can guide the moving direction of the second bracket 132 until the first buckle 1313 is engaged with the second buckle 1322a in a snap-fit manner, so that the first bracket 131 and the second bracket 132 are assembled in place.

[0046] In this solution, the first bracket 131 and the second bracket 132 are engaged with each other by the first buckle 1313 and the second buckle 1322a in a snap-fit manner, so that the connection manner between the first bracket 131 and the second bracket 132 is simple and the cost is low. In addition, the first guiding portion 1312a and the second guiding portion 1322b can guide and position the first bracket 131 and the second bracket 132, thereby improving the assembly accuracy and assembly efficiency of the knob control device 100.

[0047] Further, one of the first guiding portion 1312a and the second guiding portion 1322b is a guiding protrusion, and the other is a guiding groove, and at least a part of the guiding protrusion is located in the guiding groove. This solution can further simplify the structure of the knob bracket 130.

[0048] Of course, the first guiding portion 1312a and the second guiding portion 1322b may also be a guide rail and slider structure, and the specific structures of the first guiding portion 1312a and the second guiding portion 1322b are not limited in this article.

[0049] In the above scheme, in order to make the installation of the second bracket 132 and the first bracket 131 more stable, the end of the extended protrusion 1312 away from the first support plate 1311 can abut against the surface of the second support plate 1321 on the side facing the first bracket 131. At this time, the extended protrusion 1312 can exert a force on the second support plate 1321 away from the first bracket 131, so that the first clip 1313 and the second clip 1322a can fit more closely, thereby having better clipping performance.

[0050] In another optional solution, the end of the outer ring surface of the ring body 1322 facing the second support plate 1321 may be provided with a first limiting protrusion 1322c, and the end of the outer ring surface of the ring body 1322 facing away from the second support plate 1321 may be provided with a third buckle 1322d, and the inner ring 121 of the bearing 120 is sleeved on the ring body 1322, and the inner ring 121 of the bearing 120 is clamped between the first limiting protrusion 1322c and the third buckle 1322d. At this time, the upper and lower side edges of the inner ring 121 of the bearing 120 can be respectively abutted by the first limiting protrusion 1322c and the buckle head of the first buckle 1313, so that the inner ring 121 of the bearing 120 can be fixed.

[0051] In this solution, a snap-fitting method is adopted to facilitate the installation and disassembly of the bearing 120 and the annular body 1322 , thereby reducing the difficulty of assembling and disassembling the bearing 120 and the knob bracket 130 .

[0052] Of course, the inner ring 121 of the bearing 120 and the annular body 1322 can also be fixedly connected by interference fit, and the specific connection method between the inner ring 121 of the bearing 120 and the annular body 1322 is not limited in this article.

[0053] In another optional solution, one of the first support plate 1311 and the mounting housing 110 may be provided with a positioning hole 133, and the other may be provided with a positioning post 1104, and the positioning hole 133 and the positioning post 1104 are positioned and matched; wherein the axial direction of the positioning hole 133 is parallel to the axial direction of the opening 1103. This solution can further improve the installation accuracy of the knob bracket 130 and the mounting housing 110. In addition, the positioning post 1104 and the positioning hole 133 can also guide the first support plate 1311 in its moving direction, thereby improving the movement accuracy of the knob bracket 130. In addition, the positioning post 1104 and the positioning hole 133 can limit the rotation of the first support plate 1311, thereby further avoiding the situation where the inner ring 121 of the bearing 120 rotates during the rotation of the knob ring 140.

[0054] In the above embodiment, the positioning hole 133 or the positioning column 1104 may be located in the first area 1311 a or the second area 1311 b on the first supporting plate 1311 .

[0055] In another alternative solution, the first support plate 1311 further includes a third region 1311c. The third region 1311c can be disposed around the second region 1311b, and the positioning hole 133 or the positioning post 1104 can be located in the third region 1311c. In this solution, the third region 1311c is located outside the second region 1311b, so that the installation position of the second magnetic member 152 is not affected by the positioning hole 133 or the positioning post 1104.

[0056] In the above solution, the knob ring 140 can be of an integral structure.

[0057] In another alternative solution, the knob ring 140 can include an inner ring body 141 and an outer ring body 142 that are separately arranged. The inner ring body 141 is fixedly sleeved on the outer ring 122 of the bearing 120, and the outer ring body 142 is fixedly sleeved on the inner ring body 141. In this solution, the knob ring 140 is separately arranged, which is convenient for processing the inner ring body 141 and the outer ring body 142 of the knob ring 140 with different materials, so as to achieve better appearance effects and processing requirements.

[0058] In the above solution, the inner ring body 141 can be of a solid structure. However, the solid structure is not conducive to casting molding.

[0059] In another alternative solution, the inner ring body 141 can include a first base ring 1411 and a second base ring 1412. The first base ring 1411 can be disposed around the second base ring 1412, and an annular avoidance groove 1413 can be formed between the second base ring 1412 and the first base ring 1411. The outer ring body 142 can be disposed around the first base ring 1411. In this solution, there is an annular avoidance groove 1413 between the first base ring 1411 and the second base ring 1412, so the inner ring body 141 is of a hollow structure, which is more convenient for the inner ring body 141 to be cast. In addition, the hollow inner ring body 141 is also lighter in weight, so the overall weight of the knob control device 100 is reduced.

[0060] Further, the outer side wall of the first base ring 1411 can be provided with a fourth buckle 1411a and a third guiding portion 1441b, and the inner side wall of the outer ring body 142 can be provided with a fifth buckle 1421 and a fourth guiding portion 1422. The fourth buckle 1411a and the fifth buckle 1421 are in snap-fit connection, and the third guiding portion 1441b and the fourth guiding portion 1422 can be in guiding fit along the central axis direction of the bearing 120.

[0061] In this solution, the inner ring body 141 and the outer ring body 142 are snap-fitted through the fourth snap 1411a and the fifth snap 1421, so that the connection between the inner ring body 141 and the outer ring body 142 is simple and the cost is low. In addition, the third guiding portion 1441b and the fourth guiding portion 1422 can guide and position the inner ring body 141 and the outer ring body 142, thereby improving the assembly accuracy and assembly efficiency of the knob control device 100.

[0062] At this time, the snap on the inner ring body of the above middle frame structure is also more convenient to deform, so as to facilitate the operations of snap-fitting and disassembly.

[0063] Furthermore, one of the third guiding portion 1441b and the fourth guiding portion 1422 is a protrusion, and the other is a groove, and at least a part of the protrusion is located in the groove. This solution can further simplify the structure of the knob bracket 130.

[0064] Of course, the third guiding portion 1441b and the fourth guiding portion 1422 can also be a guide rail and slider structure, and the specific structures of the third guiding portion 1441b and the fourth guiding portion 1422 are not limited in this article.

[0065] In another alternative solution, the inner side wall of the second base ring 1412 can be provided with a second limiting convex portion 1412a and a sixth snap 1412b. The second base ring 1412 surrounds the outer ring 122 of the bearing 120, and the outer ring 122 of the bearing 120 is clamped between the second limiting convex portion 1412a and the sixth snap 1412b. At this time, the upper and lower side edges of the outer ring 122 of the bearing 120 can be respectively abutted by the buckle heads of the second limiting convex portion 1412a and the sixth snap 1412b, so as to fix the outer ring 122 of the bearing 120.

[0066] In this solution, the snap-fastening method is convenient for realizing the installation and disassembly of the bearing 120 and the knob ring 140, so the assembly and disassembly difficulty of the bearing 120 and the knob ring 140 is reduced.

[0067] The above inner ring body 141 and outer ring body 142, as well as the outer ring 122 of the inner ring body 141 and the bearing 120, can also be connected by interference fit, bonding fit, screw fit and other methods, and the specific connection methods are not limited in this article.

[0068] In the above embodiments, the device main body of the device can be provided with a knob trigger and a press trigger. When the knob bracket 130 triggers the press trigger during pressing, the corresponding control function is triggered. Similarly, when the knob ring 140 rotates, the knob trigger can be triggered, and the corresponding control function is triggered. Here, the knob trigger and the press trigger can be components such as a switch 161, a distance sensor, and a pressure sensor.

[0069] In another optional embodiment, the mounting housing 110 includes a first housing 111 and a second housing 112, the first housing 111 and the second housing 112 enclose a receiving cavity 1105, the first housing 111 may be provided with an opening 1103, the surface of the first housing 111 facing away from the receiving cavity 1105 may be a first surface 1101, and the surface of the first housing 111 facing the receiving cavity 1105 may be a second surface 1102. At least part of the first bracket 131, the first magnetic member 151 and the second magnetic member 152 are all located in the receiving cavity 1105.

[0070] The knob control device 100 may also include a switch 161 and a circuit board 162. Both the switch 161 and the circuit board 162 may be located in the accommodating cavity 1105. The switch 161 is located on the side of the circuit board 162 facing the first housing 111. When the knob bracket 130 is in the pressing position, the switch 161 may have a third gap C with the first bracket 131. Here, a certain distance is reserved between the switch 161 and the first bracket 131, so the switch 161 is not triggered and is in a closed state. When the knob bracket 130 is in the triggering position, the knob bracket 130 triggers the switch 161. At this time, the first bracket 131 presses the switch 161, and the switch 161 is turned on. The above-mentioned first gap A may specifically be the distance between the surface of the first support plate 1311 on the side facing the circuit board 162 and the top surface of the unpressed switch 161.

[0071] In this solution, a circuit board 162 and a switch 161 are installed in the accommodating cavity 1105 of the mounting shell 110 , thereby realizing modularization of the knob control device 100 and improving the usage scenarios of the knob control device 100 .

[0072] like Figure 3 As shown, the gap between the circuit board 162 and the first bracket 131 is the fourth gap D. In order to effectively trigger the switch 161, the first gap A needs to be greater than the fourth gap D, and the fourth gap D needs to be greater than the sum of the third gap C and the preset stroke of the switch 161. In addition, in order to avoid pressing to the maximum stroke of the switch 161, the sum of the third gap C and the maximum stroke of the switch 161 is greater than the fourth gap D. The maximum stroke of the switch 161 here is greater than the preset stroke of the switch 161. The preset stroke of the switch 161 here refers to the stroke that the switch 161 can be triggered, and the maximum stroke of the maximum switch 161 refers to the maximum stroke that the switch 161 can be pressed.

[0073] The knob trigger in the above embodiment can also be arranged on the circuit board 162. The knob trigger here can be an angle sensor, a photoelectric sensor and other components for detecting the knob angle of the outer ring 122 of the bearing 120. Of course, the knob trigger can also be other structures and this article does not limit it.

[0074] In another optional solution, a receiving groove 1311d is provided on one side of the first bracket 131 facing the circuit board 162, the notch of the receiving groove 1311d can be arranged opposite to the switch 161, and a pressing rib 1311d1 can be arranged at the bottom of the receiving groove 1311d, and when the knob bracket 130 is in the pressing position, the switch 161 and the pressing rib 1311d1 have the third gap C mentioned above. When the knob bracket 130 is in the triggering position, the pressing rib 1311d1 abuts against the switch 161.

[0075] In this solution, the switch 161 is arranged opposite to the receiving groove 1311d, so that the distance between the circuit board 162 and the first bracket 131 is further reduced while ensuring that the switch 161 can be effectively triggered. In addition, the switch 161 can also be hidden in the receiving groove 1311d, thereby protecting the switch 161 and improving safety.

[0076] In another optional solution, the knob control device 100 may further include a display screen 170, which is disposed on the knob bracket 130. In this case, the knob control device 100 is provided with the display screen 170, which improves the technological sense and usability of the knob control device 100. Specifically, the display screen 170 may be disposed on the surface of the second support plate 1321 on the side away from the ring body 1322.

[0077] Based on the knob control device 100 of any of the above embodiments of the present application, an embodiment of the present application further discloses a device, and the disclosed device includes the knob control device 100 of any of the above embodiments.

[0078] The device disclosed in the present application also includes a device body, which includes but is not limited to a device housing, a circuit structure, a display structure, etc. The knob control device can be arranged on the device body.
