[0001] The utility model relates to the technical field of control knobs, in particular to a knob control device and equipment. Background Art

[0002] Knob control devices are provided on equipment such as automobiles and smart home appliances, and the knob control devices can control corresponding functions of the equipment. For example, the knob control device can control functions such as the volume and temperature of the equipment. In order to improve the use 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, with the increase in the number of times the knob control device is used, the mechanical properties of the elastic member gradually decrease, resulting in a 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

[0005] The utility model discloses a knob control device and equipment to solve the problem of poor reliability of the knob control device.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A knob control device includes a hollow encoder, a knob ring and a connecting ring;

[0008] The hollow encoder includes a device body and a rotating cylinder. The rotating cylinder is sleeved outside the device body, and the rotating cylinder can rotate relative to the device body around its central axis; the connecting ring is fixedly sleeved on the outer side wall of the rotating cylinder, and the connecting ring is provided with a first magnetic member; the knob ring is provided with a second magnetic member, the knob ring is sleeved outside the connecting ring, and the knob ring and the connecting ring are magnetically connected through the first magnetic member and the second magnetic member. The knob ring can be switched between a pressing position and a triggering position relative to the connecting ring along the axis direction of the connecting ring;

[0009] The knob ring can drive the rotating cylinder to rotate relative to the device body through the connecting ring; the knob ring can overcome the magnetic force between the first magnetic member and the second magnetic member, so that the knob ring is switched 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 ring from the triggering position to the pressing position.

[0011] The technical solution adopted by the present utility model can achieve the following beneficial effects:

[0012] In the knob control device disclosed by the present utility model, when the knob ring is pressed, the knob ring can overcome the magnetic force between the first magnetic member and the second magnetic member, so that the knob ring is switched from the pressing position to the triggering position. When the pressing force on the knob ring is removed, the magnetic force between the first magnetic member and the second magnetic member can switch the knob ring 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 ring after pressing.

Detailed implementation manners

[0022] 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. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The following will, in conjunction with the drawings, detail the technical solutions disclosed in each embodiment of the present utility model.

[0024] 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 hollow encoder 110, a knob ring 120 and a connecting ring 130.

[0025] The hollow encoder 110 includes a device body 111 and a rotating cylinder 112. The rotating cylinder 112 is sleeved outside the device body 111, and the rotating cylinder 112 can rotate relative to the device body 111 about its central axis. Specifically, the device body 111 includes a hollow tube body and a mounting base integrally formed with the hollow tube body. The rotating cylinder 112 is sleeved on the hollow tube body, and the rotating cylinder 112 can rotate relative to the hollow tube body about its central axis. The specific structure and working principle of the hollow encoder 110 are well-known technologies and are not limited in this article.

[0026] The connecting ring 130 is fixedly sleeved on the outer side wall of the rotating cylinder 112. That is to say, the connecting ring 130 and the rotating cylinder 112 form an integral sleeve structure, and the connecting ring 130 and the rotating cylinder 112 can rotate together. The connecting ring 130 is provided with a first magnetic member 141.

[0027] The knob ring 120 is provided with a second magnetic member 142, and the knob ring 120 is sleeved outside the connecting ring 130. The knob ring 120 and the connecting ring 130 are magnetically connected by the first magnetic member 141 and the second magnetic member 142. Optionally, the first magnetic member 141 and the second magnetic member 142 can be electromagnets or permanent magnets.

[0028] Here, it can be understood that the knob ring 120 and the connecting ring 130 are maintained in a relatively fixed position by the magnetic force between the first magnetic member 141 and the second magnetic member 142. For example, through the magnetic attraction force between the first magnetic member 141 and the second magnetic member 142, the knob ring 120 and the connecting ring 130 are attracted together. Or, through the magnetic repulsion force between the first magnetic member 141 and the second magnetic member 142, the knob ring 120 is limited on the connecting ring 130.

[0029] The knob ring 120 can drive the rotating cylinder 112 to rotate relative to the device body 111 through the connecting ring 130. At this time, when the user rotates the knob ring 120, the knob ring 120 can drive the rotating cylinder 112 to rotate through the connecting ring 130, so as to realize the rotation function of the knob control device 100. At this time, the knob ring 120 is circumferentially stationary relative to the connecting ring 130, that is to say, the knob ring 120 and the connecting ring 130 cannot rotate relative to each other circumferentially. Here, it can be understood that the knob ring 120 and the connecting ring 130 are circumferentially limited and matched.

[0030] The knob ring 120 can be switched between a pressing position and a triggering position relative to the connecting ring 130 along the axial direction of the connecting ring 130. The axial direction of the connecting ring 130 here is as Figure 3The direction indicated by the arrow. At this time, the knob ring 120 can move axially relative to the connection ring 130. Therefore, it can be understood that the knob ring 120 can slide axially relative to the connection ring 130. The knob ring 120 can move along the axis direction of the connection ring 130, so the pressing function of the knob control device 100 can be realized. The knob ring 120 can overcome the magnetic force between the first magnetic member 141 and the second magnetic member 142, so that the knob ring 120 is switched from the pressing position to the triggering position. At this time, since the rotating cylinder 112 is relatively fixed to the connection ring 130, the knob ring 120 moves relative to the connection ring 130 and the rotating cylinder 112 along the axis direction of the connection ring 130 and the rotating cylinder 112. The magnetic force between the first magnetic member 141 and the second magnetic member 142 can switch the knob ring 120 from the triggering position to the pressing position. The pressing position of the knob ring 120 here refers to the position when no pressing force is applied to the knob ring 120, or it can be understood as the position when the knob ring 120 does not trigger the corresponding pressing function. The initial position between the knob ring 120 and the connection ring 130 maintained by the first magnetic member 141 and the second magnetic member 142. At this time, the knob ring 120 does not trigger the corresponding function. The triggering position refers to the relative position between the knob ring 120 and the connection ring 130 when a pressing force is applied to the knob ring 120. It can also be understood that the knob ring 120 triggers the corresponding pressing function. At this time, the knob ring 120 triggers the corresponding function.

[0031] During the specific operation process, as Figure 3 shown, when only a rotational movement is applied to the knob ring 120, the knob ring 120 drives the rotating cylinder 112 to rotate relative to the device body 111 through the connection ring 130. During the rotation of the rotating cylinder 112, corresponding signals can be triggered. During the rotation of the knob ring 120, the distance between the first magnetic member 141 and the second magnetic member 142 remains unchanged. Therefore, the magnetic force between the knob ring 120 and the connection ring 130 remains unchanged. Therefore, the acting force between the first magnetic member 141 and the second magnetic member 142 does not affect the rotational operation of the knob ring 120.

[0032] When a pressing force is applied to the knob ring 120, the pressing force received by the knob ring 120 is greater than the acting force between the first magnetic member 141 and the second magnetic member 142. Therefore, the knob ring 120 moves in the direction indicated by the vertically downward arrow as Figure 3 shown, until it moves to the triggering position. When the pressing force applied to the knob ring 120 is removed, the acting force between the first magnetic member 141 and the second magnetic member 142 drives the knob ring 120 to move back to its original position. Here, it can be understood that the acting force between the first magnetic member 141 and the second magnetic member 142 drives the knob ring 120 to move in the vertically upward direction, as Figure 3 shown by the vertically upward arrow, until it moves to the pressing position.

[0033] Of course, when rotating the knob ring 120, a pressing force can also be applied to the knob ring 120 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 an application environment, the rotation operation of the knob ring 120 can achieve the regulation of functions, such as the selection of temperature and volume, while the pressing operation of the knob ring 120 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.

[0034] In the embodiments disclosed in this application, the first magnetic member 141 and the second magnetic member 142 are used to reset the knob ring 120 after pressing through the magnetic force. The magnetic force between the first magnetic member 141 and the second magnetic member 142 is relatively stable, and has a longer service life compared with elastic members. Therefore, it has a better reset effect, so it is not easy to affect the pressing function of the knob control device 100, thus improving the reliability of the knob control device 100.

[0035] The hollow encoder 110 in this application can be installed in the circuit structure of the device. For example, when the device is an automobile, the hollow encoder 110 can be directly assembled on the main board of the center console of the automobile. For another example, when the device is a smart home appliance, the hollow encoder 110 can be directly assembled on the main board of the smart home appliance. Of course, the main board of the center console or the main board of the smart home appliance can also be provided with corresponding pressing trigger components, such as pressure sensors, photoelectric sensors, distance sensors and other pressing trigger components. During the pressing operation of the knob ring 120, one end of the knob ring 120 can trigger the pressing trigger component, so as to achieve the corresponding function.

[0036] In one solution, the magnetic poles of the opposite surfaces of the first magnetic member 141 and the second magnetic member 142 are the same, that is to say, the first magnetic member 141 and the second magnetic member 142 are magnetically repelled. At this time, the magnetic poles of the opposite surfaces of the first magnetic member 141 and the second magnetic member 142 can be N pole to N pole or S pole to S pole. The magnetic repulsion force between the first magnetic member 141 and the second magnetic member 142 makes the knob ring 120 and the connecting ring 130 relatively suspended.

[0037] In the specific operation process, the user applies a pressing force to the knob ring 120, and the pressing force is greater than the magnetic repulsion force between the first magnetic member 141 and the second magnetic member 142, so that the knob ring 120 is switched from the pressing position to the triggering position. When the acting force on the knob ring 120 is removed, the magnetic repulsion force between the first magnetic member 141 and the second magnetic member 142 makes the first magnetic member 141 and the second magnetic member 142 move away from each other, so that the knob ring 120 is switched from the triggering position to the pressing position.

[0038] In an alternative embodiment, the first magnetic member 141 and the second magnetic member 142 are magnetically attracted to each other. At this time, the magnetic poles of the opposite faces of the first magnetic member 141 and the second magnetic member 142 are opposite. At this time, the magnetic poles of the opposite faces of the first magnetic member 141 and the second magnetic member 142 can be N pole against S pole or S pole against N pole.

[0039] During the specific operation process, when the pressing force applied by the user to the knob ring 120 is greater than the magnetic attraction force between the first magnetic member 141 and the second magnetic member 142, the knob ring 120 drives the first magnetic member 141 to gradually move away from the second magnetic member 142, so that the knob ring 120 is switched to the trigger position. When the pressing force on the knob ring 120 is removed, the attraction force between the first magnetic member 141 and the second magnetic member 142 can switch the knob ring 120 back to the pressed position again.

[0040] This solution can achieve the magnetic attraction and cooperation between the knob ring 120 and the connecting ring 130. Therefore, the magnetic attraction and cooperation between the knob ring 120 and the connecting ring 130 are not likely to cause the knob ring 120 to shake relative to the connecting ring 130, thus improving the stability of the knob ring 120 and the connecting ring 130.

[0041] Optionally, the number of the first magnetic members 141 and the second magnetic members 142 can both be multiple, and the multiple first magnetic members 141 and the multiple second magnetic members 142 are arranged in one-to-one correspondence.

[0042] In another alternative solution, one of the connecting ring 130 and the knob ring 120 is provided with a mating recess 131, and the other is provided with a connecting buckle 1201. At least a part of the connecting buckle 1201 is located in the mating recess 131. The mating recess 131 has a first limiting surface 1311 and a second limiting surface 1312 which are oppositely arranged. Since the knob ring 120 can only move axially relative to the connecting ring 130, the connecting buckle 1201 moves axially together with the knob ring 120. Therefore, the first limiting surface 1311 and the second limiting surface 1312 are arranged along the axis direction of the connecting ring 130.

[0043] When the knob ring 120 is in the pressed position, the connecting buckle 1201 can be in contact with the first limiting surface 1311. At this time, as Figure 3 shown, the connecting buckle 1201 and the first limiting surface 1311 are in limiting cooperation in the vertically upward direction, thus avoiding the risk of excessive protrusion of the knob ring 120. When the knob ring 120 is in the trigger position, the connecting buckle 1201 is in contact with the second limiting surface 1312. At this time, as Figure 3 shown, the connecting buckle 1201 and the second limiting surface 1312 are in limiting cooperation in the vertically downward direction, thus avoiding the risk of excessive pressing of the knob ring 120.

[0044] In this solution, by cooperating with the concave portion 131 and the connecting buckle 1201, the moving distance of the knob ring 120 can be limited, thus avoiding the risks of excessive protrusion and excessive pressing of the knob ring 120, and further improving the safety and reliability of the knob control device 100.

[0045] Optionally, the number of the cooperating concave portions 131 and the connecting buckles 1201 can both be multiple, and the multiple cooperating concave portions 131 and the multiple connecting buckles 1201 can be arranged in one-to-one correspondence.

[0046] In another alternative solution, the connecting buckle 1201 can be an elastic protrusion. At this time, during the assembly process of the connecting ring 130 and the knob ring 120, the elastic protrusion is squeezed into the cooperating concave portion 131, and the elastic protrusion can move between the first limiting surface 1311 and the second limiting surface 1312. When the elastic protrusion abuts against the first limiting surface 1311, the knob ring 120 is in the pressing position. When the elastic protrusion moves to a position where it abuts against the second limiting surface 1312, the knob ring 120 is in the triggering position.

[0047] In another solution, the connecting buckle 1201 generally consists of an elastic arm and a buckle head. The elastic arm has a connecting end and a free end. The connecting end is fixed on the connecting ring 130 or the knob ring 120, and the buckle head is fixed on the free end. During the assembly process of the connecting ring 130 and the knob ring 120, the elastic arm is slightly deformed, so that the buckle can slide into the cooperating concave portion 131. At this time, the buckle head can move between the first limiting surface 1311 and the second limiting surface 1312 as the knob ring 120 moves. When the buckle head abuts against the first limiting surface 1311, the knob ring 120 is in the pressing position. When the buckle head moves to a position where it abuts against the second limiting surface 1312, the knob ring 120 is in the triggering position.

[0048] In this solution, the elastic arm is easy to deform, so it is convenient for the connecting ring 130 and the knob ring 120 to be assembled. Therefore, the assembly structure of the knob control device 100 is simplified.

[0049] The cooperating concave portion 131 in the above embodiments can be a groove or a through hole, and the first limiting surface 1311 and the second limiting surface 1312 can be two opposite inner surfaces in the groove or the through hole.

[0050] In another alternative solution, a first guiding portion 132 is provided on the outer side wall of the connecting ring 130, and a second guiding portion 1202 is provided on the inner side wall of the knob ring 120. The first guiding portion 132 and the second guiding portion 1202 can be guided and cooperated along the axial direction of the connecting ring 130.

[0051] In the specific assembly process, align the second guiding portion 1202 on the knob ring 120 with the first guiding portion 132, and then push the knob ring 120 to slide in the direction of the connecting ring 130. At this time, the first guiding portion 132 and the second guiding portion 1202 can guide the moving direction of the knob ring 120 until the connecting buckle 1201 is embedded in the mating recess 131, so that the appropriate knob ring 120 and the connecting ring 130 are assembled in place.

[0052] In this solution, the first guiding portion 132 and the second guiding portion 1202 can guide and position the knob ring 120 and the connecting ring 130, thereby improving the assembly accuracy and assembly efficiency of the knob control device 100.

[0053] In the above embodiment, the number of the first guiding portion 132 and the second guiding portion 1202 can both be multiple, and the multiple first guiding portions 132 and the multiple second guiding portions 1202 are arranged in one-to-one correspondence.

[0054] Further, one of the first guiding portion 132 and the second guiding portion 1202 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 ring 120.

[0055] Of course, the first guiding portion 132 and the second guiding portion 1202 can also be a guide rail and slider structure, and the specific structures of the first guiding portion 132 and the second guiding portion 1202 are not limited in this article.

[0056] In another alternative solution, a first abutting convex portion 133 and a third guiding portion 134 can be provided on the inner side wall of the connecting ring 130, and a fourth guiding portion 1121 can be provided on the outer side wall of the rotating cylinder 112. The connecting ring 130 can be in interference fit with the rotating cylinder 112 through the first abutting convex portion 133. The third guiding portion 134 can be in guiding cooperation with the fourth guiding portion 1121 along the axis direction of the connecting ring 130.

[0057] In this solution, the first abutting convex portion 133 can abut against the outer side wall of the connecting ring 130, so that the fixed connection between the connecting ring 130 and the knob cylinder can be realized. Therefore, the assembly difficulty and disassembly difficulty of the connecting ring 130 and the rotating cylinder 112 are reduced.

[0058] In addition, the third guiding portion 134 and the fourth guiding portion 1121 can guide and position the connecting ring 130 and the rotating cylinder 112, thereby improving the assembly accuracy and assembly efficiency of the knob control device 100.

[0059] Optionally, one of the third guiding portion 134 and the fourth guiding portion 1121 may be a guiding protrusion, and the other may be a guiding groove, and at least part of the guiding protrusion is located in the guiding groove. This solution can further simplify the structure of the knob ring 120.

[0060] Optionally, the first abutting protrusion 133 may be an elastic protrusion or a buckle. The first abutting protrusion 133 may directly abut against the outer side wall of the rotating cylinder 112, or a clamping groove is provided on the outer side wall of the rotating cylinder 112, and at least part of the first abutting protrusion 133 may be in the clamping groove.

[0061] In the above solution, the knob ring 120 may be of an integral structure.

[0062] In another alternative embodiment, the knob ring 120 may include an inner ring body 121 and an outer ring body 122 that are separately arranged, and the outer ring body 122 may be fixedly sleeved on the inner ring body 121. The inner ring body 121 may be sleeved on the connecting ring 130. The first magnetic member 141 may be provided on the side wall of the inner ring body 121, and one of the mating recess 131 and the connecting buckle 1201 may be provided on the inner side wall of the inner ring body 121.

[0063] In this solution, the knob ring 120 is separately arranged, which is convenient for processing the inner ring body 121 and the outer ring body 122 of the knob ring 120 with different materials, so as to achieve better appearance effects and processing requirements.

[0064] In another solution, when the knob ring 120 is of a split structure, the inner ring body 121 is slidably matched with the above-mentioned connecting ring 130, and the above-mentioned second guiding portion 1202 may be provided on the inner side wall of the inner ring body 121.

[0065] Further, a first buckle 12111 and a fifth guiding portion 12112 may be provided on the outer side wall of the inner ring body 121, and a second buckle 1221 and a sixth guiding portion 1222 may be provided on the inner side wall of the outer ring body 122. The first buckle 12111 and the second buckle 1221 are snap-fitted. The fifth guiding portion 12112 and the sixth guiding portion 1222 may be guidingly matched along the axis direction of the connecting ring 130.

[0066] In this solution, the inner ring body 121 and the outer ring body 122 are snap-fitted through the first buckle 12111 and the second buckle 1221, so that the connection method between the inner ring body 121 and the outer ring body 122 is simple and the cost is low. In addition, the fifth guiding portion 12112 and the sixth guiding portion 1222 can guide and position the inner ring body 121 and the outer ring body 122, thereby improving the assembly accuracy and assembly efficiency of the knob control device 100.

[0067] Further, one of the fifth guiding portion 12112 and the sixth guiding portion 1222 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 ring 120.

[0068] Of course, the fifth guiding portion 12112 and the sixth guiding portion 1222 can also be a guide rail and slider structure, and the specific structures of the fifth guiding portion 12112 and the sixth guiding portion 1222 are not limited in this article.

[0069] In the embodiments disclosed in the present application, the outer ring body 122 can be used to trigger the above-mentioned pressing trigger member, and it can be understood here that the outer ring body 122 can directly abut against or press on the pressing trigger member.

[0070] In another alternative embodiment, the inner ring body 121 can include a ring main body 1211 and a pressing convex portion 1212, and the ring main body 1211 and the pressing convex portion 1212 can be arranged along the axis direction of the connecting ring 130. At this time, a pressing convex portion 1212 extends from one end of the ring main body 1211. The outer ring body 122 can be fixedly sleeved on the ring main body 1211, and one of the mating concave portion 131 and the connecting buckle 1201 can be arranged on the inner side wall of the ring main body 1211. In this solution, by providing the pressing convex portion 1212 on the inner ring body 121, the triggering operation of the pressing trigger member can be realized. Since the pressing convex portion 1212 is provided on the inner ring body 121, the appearance of the outer ring body 122 is not affected, thereby improving the appearance performance of the knob ring 120. In addition, the pressing convex portion 1212 is provided on the inner ring body 121, which is also convenient for assembling the knob control device 100. In addition, the pressing convex portion 1212 can also shorten the pressing distance of the knob ring 120.

[0071] Optionally, the structure for connecting the knob ring 120 to the connecting ring 130 and the guiding structure can both be arranged on the ring main body 1211.

[0072] In another alternative embodiment, the knob control device 100 can further include a circuit board 150 and a switch 151, and the switch 151 and the hollow encoder 110 are arranged side by side on the circuit board 150. The device body 111 and the switch 151 can both be electrically connected to the circuit board 150. When the knob ring 120 is in the pressing position, there is a first gap between the switch 151 and the knob ring 120. Here, a certain distance is reserved between the switch 151 and the knob ring 120, so the switch 151 is not triggered. The first gap between the switch 151 and the knob ring 120 can be understood as the gap between the switch 151 and the above-mentioned pressing convex portion 1212. When the knob ring 120 is in the triggering position, the knob ring 120 triggers the switch 151.

[0073] In this solution, the knob control device 100 is provided with a circuit board 150 and a switch 151, thereby realizing modularization of the knob control device 100 and improving the use scenarios of the knob control device 100. In addition, the knob control device 100 has a circuit board 150 for electrically connecting to the hollow encoder 110, so that the installation position of the knob control device 100 is relatively flexible.

[0074] like Figure 3 As shown, the width of the first gap between the switch 151 and the knob ring 120 is d. Figure 5 As shown, the movable distance of the connecting buckle 1201 in the matching recess 131 is a. At this time, it can also be understood that when the connecting buckle 1201 is in the pressing position, there is a second gap between the side surface of the connecting buckle 1201 facing the second limiting surface 1312 and the second limiting surface 1312, and the distance of the second gap is a. At this time, the sum of d and the trigger stroke of the switch 151 needs to be less than a. At this time, it is ensured that the displacement of the knob ring 120 can trigger the switch 151.

[0075] In another optional solution, the knob control device 100 may further include a mounting housing 160 , which may provide a mounting base for other components of the knob control device 100 . In this case, the mounting housing 160 and the circuit board 150 may be fixed on the mounting housing 160 .

[0076] In one solution, the mounting housing 160 may be a mounting plate, in which case the circuit board 150 , the hollow encoder 110 , the knob ring 120 and the connecting ring 130 are all located on the same side of the mounting plate.

[0077] In another optional solution, the mounting plate may be provided with a through hole, and the circuit board 150 and the knob ring 120 may be located on opposite sides of the mounting plate. In this case, the end of the hollow encoder 110 away from the circuit board 150 may pass through the through hole and extend to the other side of the mounting plate. In this case, the pressing protrusion 1212 of the knob ring 120 may pass through the through hole, thereby facilitating the knob ring 120 to trigger the switch 151.

[0078] Optionally, the outer diameter of the outer ring body 122 of the knob ring 120 can be larger than the through hole, and the pressing protrusion on the inner ring body 121 can pass through the through hole. Here, the pressing protrusion 1212 can be an annular structure, so the outer diameter of the pressing protrusion 1212 is smaller than the outer diameter of the through hole. At this time, in order to avoid interference between the outer ring body 122 and the mounting shell 160, a third gap is reserved between the outer ring body 122 and the mounting shell 160. The distance of the third gap is as follows: Figure 3As shown by c in [the figure], c needs to be greater than a. At this time, when pressing and rotating, the knob ring 120 does not interfere with the mounting housing 160 and the switch 151 does not experience overvoltage, and the adjustment is c > a > b + d, where d can be understood as the trigger stroke of the switch 151.

[0079] In another alternative embodiment, as Figure 3 shown, the mounting housing 160 may be provided with a receiving cavity 1601 and an opening 1602 communicating with the receiving cavity 1601. The circuit board 150 may be located within the receiving cavity 1601. One end of the device body 111 and the rotating cylinder 112 facing away from the circuit board 150 extends out of the mounting housing 160 through the opening 1602, and a part of the knob ring 120 may be located outside the mounting housing 160.

[0080] Specifically, the hollow tube of the rotating cylinder 112 and the device body 111 extends out of the mounting housing 160 through the opening 1602. At least a part of the connecting ring 130 is located outside the mounting housing 160, and the connecting ring 130 is sleeved on the rotating cylinder 112. The outer ring body 122 of the knob ring 120 and the ring body 1211 of the inner ring body 121 are both located outside the mounting housing 160. The pressing convex part 1212 of the inner ring body 121 extends into the receiving cavity 1601 through the opening 1602 and faces the switch 151. At this time, the outer diameter of the outer ring body 122 of the knob ring 120 is greater than the diameter of the opening 1602, so the outer ring body 122 can block the opening 1602. At this time, the distance between the outer ring body 122 and the outer surface of the mounting housing 160 is the above-mentioned c.

[0081] In this solution, the circuit board 150 and the switch 151 are installed in the receiving cavity 1601 of the mounting housing 160. At this time, the mounting housing 160 can protect the circuit board 150 and the switch 151, thus improving the safety of the knob control device 100.

[0082] Optionally, the mounting housing 160 may include a first housing 161 and a second housing 162. The first housing 161 and the second housing 162 may enclose the receiving cavity 1601, and the above-mentioned opening 1602 may be provided on the first housing 161. The first housing 161 and the second housing 162 may be connected by components such as bolts and rivets. Of course, the first housing 161 and the second housing 162 may also be connected by other components, which are not limited in this article.

[0083] In another alternative solution, the knob control device 100 may further include a screen bracket 171 and a display screen 172. The screen bracket 171 may include a support plate 1711 and a protruding portion 1712. The protruding portion 1712 may be disposed on the side of the support plate 1711 facing the hollow encoder 110. The device body 111 may be provided with a mounting groove 1111, and the mounting groove 1111 here is the hollow area of the above-mentioned hollow tube body. At least a part of the protruding portion 1712 is located in the mounting groove 1111, and the protruding portion 1712 may be in interference fit with the mounting groove 1111. At this time, the protruding portion 1712 is fixedly connected to the hollow tube body.

[0084] In this solution, the knob control device 100 is provided with a display screen 172, thus improving the technological sense and performance of the knob control device 100.

[0085] In the above solution, a guiding portion and a buckle may be provided on the outer sidewall of the protruding portion 1712 and the inner sidewall of the hollow tube body. Therefore, the protruding portion 1712 and the hollow tube body can be fixedly connected through the guiding portion and the buckle. Of course, they can also be fixedly connected through other structures, which are not limited in this article.

[0086] In another alternative solution, the knob control device 100 may further include a speaker 180. The speaker 180 is connected to the hollow encoder 110. When the rotating cylinder 112 rotates, the speaker 180 can emit corresponding sounds. This solution can further improve the technological sense and performance of the knob control device 100.
