Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic devices, and in particular, to a crown module, a control method for the crown module, and an electronic device. Background Art

[0002] As the application field of electronic devices expands, many electronic devices are equipped with buttons that can be rotated, such as smart watches and smart glasses. At present, the use experience of the crown is relatively simple and cannot meet the different operation needs of different users. Summary of the invention

[0003] The embodiments of the present application provide a crown module, a control method for the crown module, and an electronic device to improve the problem of the single usage experience of the crown module.

[0004] In order to achieve the above-mentioned purpose, this application adopts the following technical solution.

[0005] In the first aspect, an embodiment of the present application provides a crown module. The crown module includes a crown, a rotating shaft, a capsule, and an adjustment structure. One end of the rotating shaft is connected to the crown; the capsule abuts against the rotating shaft; the adjustment structure is connected to the capsule, and the adjustment structure is used to adjust the volume of the capsule to change the damping of the crown. In this way, the volume of the capsule can be adjusted by the adjustment structure to change the damping of the crown. When the user rotates the crown, the smoothness is related to the damping of the crown. For example, the user adjusts the volume of the capsule to a smaller size through the adjustment structure, so that the damping of the crown is reduced. When the crown is rotated, the resistance of the shaft is small, and the shaft rotates more smoothly. The user adjusts the volume of the capsule to a larger size through the adjustment structure, so that the damping of the crown is increased. When the crown is rotated, the resistance of the shaft is large, and the shaft has a sense of retardation. In this way, the user can adjust the damping size according to his own needs, so that the crown module can meet the different usage needs of different users. Make the crown module match more users.

[0006] In conjunction with the first aspect, in some achievable ways, the capsule is provided with a gas storage space for filling gas, and the adjustment structure includes an air pump, which is connected to the gas storage space. In this way, the air pump can inflate the gas storage space to increase the volume of the capsule. Alternatively, the air pump can discharge part of the gas in the gas storage space to reduce the volume of the capsule. The increase or decrease in the volume of the capsule can change the damping of the crown.

[0007] In combination with the first aspect, in some achievable ways, the capsule is provided with a liquid storage space for accommodating liquid, and the regulating structure includes a liquid pump and a liquid storage tank, and the liquid storage tank and the liquid storage space are both connected to the liquid pump. In this way, the liquid pump can transport the liquid in the liquid storage tank to the liquid storage space, thereby increasing the volume of the capsule. Alternatively, the liquid pump transports the liquid in the liquid storage space to the liquid storage tank, thereby reducing the volume of the capsule. While adjusting the volume of the capsule, the flow of the liquid forms a closed loop to prevent liquid leakage.

[0008] In combination with the first aspect, in some achievable ways, the crown module further includes: a base. The end of the shaft away from the crown is rotatably connected to the base, the side of the capsule away from the shaft abuts the base, the crown is arranged on the surface of the base, and the adjustment structure is connected to the base. In this way, the base and the shaft are both in abutment with the capsule, the shaft and the crown can rotate relative to the base together, and after the volume of the capsule changes, the damping of the shaft and the crown changes together, so that the friction force when the shaft and the base rotate relative to each other is adjusted. Because the crown is arranged on the surface of the base, the user can avoid the base from applying torque to the crown.

[0009] In conjunction with the first aspect, in some achievable ways, the crown module further includes: a controller. The controller is connected to the adjustment structure signal, and the controller is used to control the adjustment structure so that the damping of the crown reaches the target damping. In this way, the controller can adjust the volume of the capsule according to the needs to achieve the user's target damping, thereby meeting the needs of different users. Alternatively, it can meet the needs of the same user in different usage scenarios.

[0010] In combination with the first aspect, in some achievable ways, the crown module further includes: a friction sensor. The friction sensor is used to sense the friction force when the shaft rotates; the controller is used to determine the current damping of the crown according to the friction force sensed by the friction sensor. Because the damping of the crown is different, the friction force when the shaft rotates is different, and the current damping of the crown can be determined by sensing the friction force when the shaft rotates. The controller then controls the adjustment structure according to the relationship between the current damping and the target damping so that the damping of the crown reaches the target damping.

[0011] In combination with the first aspect, in some achievable ways, the controller is used to determine the current damping of the crown according to the friction force sensed by the friction force sensor, including: based on the friction force when the shaft rotates being the first friction force, determining the current damping to be the fifth damping. Based on the friction force when the shaft rotates being the second friction force, determining the current damping to be the sixth damping. The first friction force is greater than the second friction force, and the fifth damping is greater than the sixth damping.

[0012] In combination with the first aspect, in some achievable ways, the crown module further includes: a volume sensor. The volume sensor is used to sense the current volume of the capsule; the controller is used to determine the current damping of the crown according to the current volume sensed by the volume sensor. Because the volume of the capsule is different, the damping of the crown is different, and the current damping of the crown can be determined by obtaining the current volume of the capsule. The controller then controls the adjustment structure according to the relationship between the current damping and the target damping so that the damping of the crown reaches the target damping.

[0013] In combination with the first aspect, in some achievable manners, the controller is used to determine the current damping of the crown according to the current volume sensed by the volume sensor, including: determining the current damping to be the third damping based on the friction force when the shaft rotates being the first volume. Determining the current damping to be the fourth damping based on the friction force when the shaft rotates being the second volume. The first volume is greater than the second volume, and the third damping is greater than the fourth damping.

[0014] In conjunction with the first aspect, in some achievable ways, the crown module further comprises: a trigger. The trigger is connected to the controller signal, the trigger is used to input an instruction, and transmit the instruction to the controller, the instruction is used to indicate the target damping. In this way, the user can input an instruction indicating the target damping through the trigger according to his / her own needs, so that the crown module can achieve the user's desired experience.

[0015] In combination with the first aspect, in some achievable methods, the crown module further includes: an acquisition device. The acquisition device is connected to the controller signal, and the acquisition device is used to acquire the rotation parameter of the shaft; the controller is also used to: acquire the rotation parameter and determine the target damping according to the rotation parameter. In this way, the controller can determine the target damping according to the rotation parameter when the shaft rotates, and further control the adjustment structure to make the damping of the crown reach the target damping. The rotation parameter when the shaft rotates is matched with the target damping of the crown to enhance the user experience.

[0016] In combination with the first aspect, in some achievable methods, the rotation parameter includes: the angular acceleration of the rotating shaft. The acquisition device includes: an angular acceleration sensor, which is used to sense the angular acceleration of the rotating shaft. The controller is used to determine the target damping according to the angular acceleration sensed by the angular acceleration sensor, including: based on the angular acceleration being greater than or equal to zero, determining the target damping to be the first damping; based on the angular acceleration being less than zero, determining the target damping to be the second damping; the first damping is less than the second damping. When using the crown module, the user applies a torque to the crown, and the torque is transmitted to the rotating shaft to rotate the rotating shaft around the axis. The useful work of the user on the rotating shaft is proportional to the difference between the torque and the maximum static friction force of the rotating shaft and the angular acceleration of the rotating shaft. Therefore, the angular acceleration of the rotating shaft is related to the torque applied by the user to the crown. If the angular acceleration is greater than or equal to zero, it means that the torque on the shaft is greater than or equal to the maximum static friction of the shaft, the torque applied by the user to the crown is large, and the user expects the shaft to rotate quickly. At this time, the controller determines the target damping to be the first damping, so that the crown is relatively smoother, so as to meet the user's expectation of quickly rotating the shaft. If the angular acceleration is less than zero, it means that the force on the shaft is less than the maximum static friction of the shaft, the force applied by the user to the crown is small, and the user expects the shaft to rotate slowly. At this time, the controller determines the target damping to be the second damping, so that the crown is relatively more retarded, so as to meet the user's expectation of slowly rotating the shaft.

[0017] In conjunction with the first aspect, in some practicable manners, the angular acceleration sensor is a light sensor. The light sensor can obtain the angular acceleration of the rotating shaft in real time and transmit the information carrying the angular acceleration to the controller.

[0018] In combination with the first aspect, in some achievable methods, the controller includes: a processor and a signal generator. The processor is used to obtain the target damping according to the rotation parameter, determine the target volume of the capsule corresponding to the target damping, and send a control signal including the parameter of the target volume to the signal generator; the signal generator is used to generate an adjustment signal for adjusting the volume of the capsule according to the control signal, and send it to the adjustment structure. In this way, the controller converts the rotation parameter into an adjustment signal for adjusting the volume of the capsule, and the adjustment structure adjusts the volume of the capsule to the target volume after receiving the adjustment signal.

[0019] In combination with the first aspect, in some achievable methods, the capsule is an annular structure, and the annular structure is sleeved on the shaft. In this way, the outer periphery of the shaft can abut against the capsule of the annular structure, so that the relative force between the shaft and the capsule is more uniform. In addition, the annular structure is sleeved on the shaft, which can prevent the capsule and the shaft from sliding relative to each other when the user rotates the shaft, affecting the user experience.

[0020] In combination with the first aspect, in some achievable manners, the crown module includes a plurality of capsules, which are spaced apart along the axial direction of the shaft, and each capsule is connected to the adjustment structure. In this way, the interaction force between the shaft and the capsule is more evenly distributed along the axial direction of the shaft, and bending due to large internal stress caused by local force on the shaft can be avoided.

[0021] In a second aspect, an embodiment of the present application provides a control method for a crown module. The control method is applied to any crown module provided in the first aspect, and the method comprises:

[0022] Obtain the rotation parameters of the shaft; determine the damping of the crown as the target damping according to the rotation parameters; and control the adjustment structure so that the damping of the crown reaches the target damping. In this way, the control method of the crown module can control the damping of the crown module to the target damping according to the rotation parameters of the shaft, so that the crown module in the target damping state is more suitable for the current state of the shaft.

[0023] In conjunction with the second aspect, in some achievable manners, the rotation parameter includes an angular acceleration of the rotation axis;

[0024] The step of determining the damping of the crown as the target damping according to the rotation parameter comprises:

[0025] Based on the angular acceleration being greater than or equal to zero, the target damping is determined to be the first damping; based on the angular acceleration being less than zero, the target damping is determined to be the second damping; the first damping is less than the second damping. In this way, when the angular acceleration is greater than or equal to zero, the target damping is smaller, and the rotation speed of the shaft is faster under the same torque. When the angular acceleration is less than zero, the target damping is larger, and the rotation speed of the shaft is slower under the same torque. By adjusting the damping according to the angular acceleration of the shaft, the damping size can be adjusted according to the torque size.

[0026] In a third aspect, an embodiment of the present application provides an electronic device. The electronic device comprises: a housing and any one of the crown modules provided in the first aspect. The crown module is connected to the housing. Because the damping of the crown module can be adjusted, the user can adjust the damping of the crown module according to needs, thereby improving the user's experience of using the electronic device.

[0027] In conjunction with the third aspect, in some achievable manners, the housing is connected to the base of the crown module; the crown is located on a side of the base away from the housing. In this way, the housing and the base both avoid the crown, making it easier for the user to apply torque to the crown and to adjust the crown operation.

[0028] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, in which a computer program or instruction is stored. When the computer program or instruction is executed by a processing device, any one of the methods provided in the second aspect is implemented. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0042] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0044] Figure 1a FIG. 1 is a schematic diagram of the structure of an electronic device 10. Figure 1a As shown, the electronic device 10 may be a game console, a smart watch, a smart bracelet or smart glasses, etc. Among them, the smart glasses may be myopia glasses, hyperopia glasses, augmented reality (AR) glasses or virtual reality (VR) glasses, etc. Figure 1a A smart watch. Figure 1b FIG. 1 is a schematic diagram of the structure of another electronic device 10 . Figure 1b The electronic device 10 is a pair of smart glasses.

[0045] like Figure 1a and Figure 1b As shown, the electronic device 10 includes a housing 11 and a crown module 100, and the crown module 100 is connected to the housing 11. In some embodiments, the electronic device 10 may further include a display screen 12, and the display screen 12 is connected to the housing 11. In some embodiments, the display screen 12 may be a touch display screen.

[0046] The crown module 100 is an adjustment mechanism of the electronic device 10. For example, the crown module 100 can adjust the interface displayed on the display screen 12. The crown module 100 can be used to translate or zoom the interface displayed on the display screen 12. Among them, after the user applies torque to the crown module 100, the interaction efficiency of the crown module 100 and the display screen 12 and the user's hand feel will affect the operating experience.

[0047] Interaction efficiency refers to the relationship between the display feedback of the electronic device after the user applies torque to the crown. Among them, the display-control ratio is an important indicator of interaction efficiency. The display-control ratio w is defined as: the ratio of the amount of picture change Δc in the display screen to the arc length Δd of the crown rotation, that is: w = Δc / Δd. Furthermore, the arc length Δd of the crown rotation is proportional to the torque F given to the crown by the user, that is: Δd = f(F); combined with the above formula, it can be seen that: w = Δc / f(F). It can be seen that the display-control ratio w is directly related to the torque F given to the crown by the user. If the display control is relatively small, the amount of picture change Δc in the display screen is still small after the user applies a large force to the crown, and the interaction efficiency is low. If the display control is relatively large, the amount of picture change Δc in the display screen is large when the user applies a small force to the crown, and the user's desired target cannot be accurately located, affecting the user's experience.

[0048] Therefore, the crown module 100 provided in the embodiment of the present application has adjustable damping. The damping is proportional to the maximum static friction when the crown module 100 rotates relative to the shell 11. If the damping is large, the maximum static friction is large, and after the user gives the crown module 100 the same torque, the amount of change in the picture is small, and the display-control ratio is small. If the damping is small, the maximum static friction is small, and after the user gives the crown module 100 the same torque, the amount of change in the picture is large, and the display-control ratio is large. In this way, the damping of the crown module 100 is adjustable, so that the display-control ratio of the electronic device 10 is adjustable, wherein, when high interaction efficiency is required, the display-control ratio can be increased; when precise positioning is required, the display-control ratio can be reduced to increase the user experience. In the embodiment of the present application, the display-control ratio is adjusted by adjusting the damping size of the crown module 100.

[0049] Figure 2 This is a schematic diagram of the structure of the crown module 100 provided in the embodiment of the present application. Figure 2The crown module 100 includes a crown 110, a rotating shaft 120, a capsule 130 and an adjustment structure 140. One end of the rotating shaft 120 is connected to the crown 110, and the capsule 130 abuts against the rotating shaft 120. The adjustment structure 140 is in communication with the capsule 130, and the adjustment structure 140 is used to adjust the volume of the capsule 130 to change the damping of the crown 110. The capsule 130 abuts against the rotating shaft 120. If the volume of the capsule 130 increases, the contact area between the capsule 130 and the rotating shaft 120 increases. When the capsule 130 and the rotating shaft 120 rotate relative to each other, the greater the friction force, the greater the resistance to the rotating shaft 120. Conversely, if the volume of the capsule 130 decreases, the resistance to the rotating shaft 120 decreases. In this way, the volume of the capsule 130 can be adjusted by the adjustment structure 140 to change the damping of the crown 110. When the user rotates the crown 110, the degree of smoothness is related to the damping of the crown 110. For example, the user adjusts the volume of the capsule 130 to a smaller size through the adjustment structure 140, so that the damping of the crown 110 is reduced. When the crown 110 is rotated, the resistance of the shaft 120 is small, and the shaft 120 rotates more smoothly. The user adjusts the volume of the capsule 130 to a larger size through the adjustment structure 140, so that the damping of the crown 110 is increased. When the crown 110 is rotated, the resistance of the shaft 120 is large, and the shaft 120 has a sense of retardation. In this way, the user can adjust the damping size according to their own needs, so that the crown module 100 can meet the different usage needs of different users. The crown module 100 can match more users.

[0050] In addition, if the user expects the display control to be larger when the same torque is applied to the crown 110 and the adjustment is fast, this can be achieved by reducing the volume of the capsule 130 and reducing the damping. If the user expects the display control to be smaller when the same torque is applied to the crown 110 and the adjustment accuracy is improved, this can be achieved by increasing the volume of the capsule 130 and increasing the damping.

[0051] The embodiment of the present application does not limit the shape of the crown 110. For example, the crown 110 may be cylindrical, prismatic, etc. In some embodiments, the surface of the crown 110 is provided with a protrusion, which can increase friction and prevent relative sliding when the user operates. The embodiment of the present application does not limit the shape of the shaft 120. For example, the shaft 120 may be cylindrical, prismatic, etc.

[0052] The embodiment of the present application does not limit the connection method of the crown 110 and the shaft 120. For example, the crown 110 and the shaft 120 can be connected by a glue layer. Alternatively, the crown 110 and the shaft 120 are interference fit. Alternatively, the crown 110 and the shaft 120 can be connected as an integral molded part.

[0053] The embodiment of the present application does not limit the shape of the capsule 130. For example, in some embodiments, the capsule 130 may be an annular structure, which is sleeved on the shaft 120. The outer periphery of the shaft 120 may abut against the capsule 130 of the annular structure, so that the relative force between the shaft 120 and the capsule 130 is more uniform. In addition, the annular structure is sleeved on the shaft 120, which can prevent the capsule 130 and the shaft 120 from sliding relative to each other when the user rotates the shaft 120, affecting the user experience. In other embodiments, the capsule 130 may be an arc-shaped structure, and the arc-shaped structure abuts against the outer wall of the shaft 120. When the arc-shaped structure abuts against the side away from the shaft 120 and other structures (such as the base 150 described below), the arc-shaped structure and the shaft 120 can be in an abutment state all the time to prevent the arc-shaped structure from falling off. In other embodiments, the shape of the capsule 130 may be spherical, ellipsoidal, etc.

[0054] The embodiment of the present application does not limit the material of the capsule 130. For example, the material of the capsule 130 is an elastic material such as rubber, which has good elastic properties. When the volume of the capsule 130 increases, the pressure inside the capsule 130 causes the elastic material to be stretched, and the volume of the capsule 130 increases. When the volume of the capsule 130 decreases, the pressure inside the capsule 130 decreases, causing the elastic material to retract, thereby preventing the capsule 130 from rupturing due to a large change in internal stress. In other embodiments, the material of the capsule 130 can be polyethylene, polyvinyl chloride, and other materials.

[0055] The embodiment of the present application does not limit the number of capsules 130. For example, the number of capsules 130 may be one, two, three or more. In the embodiment where there are multiple capsules 130, the multiple capsules 130 are arranged at intervals along the axial direction of the rotating shaft 120, and each capsule 130 is connected to the adjustment structure 140. In this way, along the axial direction of the rotating shaft 120, the interaction force between the rotating shaft 120 and the capsule 130 is more evenly distributed, which can avoid bending due to large internal stress caused by local force on the rotating shaft 120. In the embodiment where there are multiple capsules 130, the volume of each capsule 130 can be independently controlled by the adjustment structure 140, so that the volume of each capsule 130 can be different, or the volume of each capsule 130 can be adjusted together by the adjustment structure 140, and the volume of each capsule 130 is the same.

[0056] The embodiment of the present application does not limit the type of the capsule 130. For example, the capsule 130 is an air capsule or a liquid capsule. Figure 3a and Figure 3b Provide an exemplary introduction.

[0057] Figure 3a A schematic structural diagram of an adjustment structure 140 and a capsule 130 provided in an embodiment of the present application. Figure 3aIn the embodiment, the bladder 130 is an air bag, and the bladder 130 is provided with an air storage space 131, and the air storage space 131 is used to fill the air. The regulating structure 140 includes an air pump 141, and the air pump 141 is connected to the air storage space 131. In this way, the air pump 141 can inflate the air storage space 131, thereby increasing the volume of the bladder 130. Alternatively, the air pump 141 can discharge part of the air in the air storage space 131, thereby reducing the volume of the bladder 130.

[0058] The embodiment of the present application does not limit the type of gas in the gas storage space 131. For example, in some embodiments, the gas filled in the gas storage space 131 is air. In this way, the air pump 141 is connected to the atmosphere, and the air in the environment is transmitted to the gas storage space 131, which can save costs and does not need to be provided with a gas tank for storing gas. In other embodiments, the gas filled in the gas storage space 131 can be nitrogen or helium. The regulating structure 140 can be provided with a gas tank for storing nitrogen or helium.

[0059] Figure 3b A schematic structural diagram of another adjustment structure 140 and capsule 130 provided in an embodiment of the present application. Figure 3b In the embodiment, the capsule 130 is a liquid capsule, and the capsule 130 is provided with a liquid storage space 132, and the liquid storage space 132 is used to fill the liquid. The regulating structure 140 includes a liquid pump 142 and a liquid storage tank 143, and the liquid storage tank 143 and the liquid storage space 132 are both connected to the liquid pump 142. In this way, the liquid pump 142 can transport the liquid in the liquid storage tank 143 to the liquid storage space 132, thereby increasing the volume of the capsule 130. Alternatively, the liquid pump 142 transports the liquid in the liquid storage space 132 to the liquid storage tank 143, thereby reducing the volume of the capsule 130. While adjusting the volume of the capsule 130, the flow of the liquid forms a closed loop to prevent leakage of the liquid. The embodiment of the present application does not limit the liquid, for example, it can be water or liquid organic matter.

[0060] Please return to Figure 2 In some embodiments, the crown module 100 further includes a base 150, and one end of the rotating shaft 120 away from the crown 110 is rotatably connected to the base 150. The side of the capsule 130 away from the rotating shaft 120 abuts against the base 150, the crown 110 is disposed on the surface of the base 150, and the adjustment structure 140 is connected to the base 150. In this way, the base 150 and the rotating shaft 120 are both abutted against the capsule 130, and the rotating shaft 120 and the crown 110 can rotate relative to the base 150 together. After the volume of the capsule 130 changes, the damping of the rotating shaft 120 and the crown 110 changes together, so that the friction force when the rotating shaft 120 and the base 150 rotate relative to each other is adjusted. Because the crown 110 is disposed on the surface of the base 150, the user can apply torque to the crown 110.

[0061] Exemplarily, a mounting hole is provided on the base 150 , and one end of the rotating shaft 120 away from the crown 110 is located in the mounting hole, and the rotating shaft 120 is rotatably connected to the mounting hole, so that the rotating shaft 120 rotates around the axial direction of the rotating shaft 120 .

[0062] In other embodiments, the side of the capsule 130 away from the rotating shaft 120 is connected to the base 150, for example, by an adhesive layer.

[0063] In some embodiments of the present application, the base 150 and the housing 11 (such as Figure 1a The crown 110 is located on the side of the base 150 away from the housing 11. In this way, it is convenient for the user to apply torque to the crown 110. Exemplarily, the connection method between the base 150 and the housing 11 is not limited, for example, the base 150 and the housing 11 are connected as an integral molded part. Alternatively, the base 150 and the housing 11 are connected by a glue layer, etc.

[0064] In the embodiment of the present application, the volume of the capsule 130 adjusted by the adjustment structure 140 can be manually controlled by the user or controlled by the controller. Figure 2 In the embodiment, the crown module 100 may further include: a controller 160, the controller 160 is connected to the adjustment structure 140 by signal, and the controller 160 is used to control the adjustment structure 140 so that the damping of the crown 110 reaches the target damping. In this way, the controller 160 can adjust the volume of the capsule 130 according to the needs to achieve the user's target damping, thereby meeting the needs of different users. Alternatively, it can meet the needs of the same user in different usage scenarios.

[0065] It is understood that, in some embodiments, the controller 160 may first obtain the current damping of the crown 110. If the current damping is not equal to the target damping, the controller 160 controls the adjustment structure 140 to make the damping of the crown 110 reach the target damping.

[0066] Figure 4a A control structure diagram of the crown module 100 provided in the embodiment of the present application. Figure 4a The crown module 100 also includes a friction sensor 171, which is used to sense the friction force when the shaft 120 rotates. The friction sensor 171 is signal-connected to the controller 160. The controller 160 is used to determine the current damping of the crown 110 based on the friction force sensed by the friction sensor 171. Because the damping of the crown 110 is different, the friction force when the shaft 120 rotates is different. Therefore, the current damping of the crown 110 can be determined by sensing the friction force when the shaft 120 rotates. The controller 160 then controls the adjustment structure 140 based on the relationship between the current damping and the target damping so that the damping of the crown 110 reaches the target damping.

[0067] Exemplarily, the controller 160 is used to determine the current damping of the crown 110 according to the friction force sensed by the friction sensor 171, including: based on the friction force when the shaft 120 rotates being the first friction force, determining the current damping to be the fifth damping. Based on the friction force when the shaft 120 rotates being the second friction force, determining the current damping to be the sixth damping. The first friction force is greater than the second friction force, and the fifth damping is greater than the sixth damping.

[0068] In the case where this magnitude relationship is satisfied, the embodiment of the present application does not limit the relationship between the friction force sensed by the friction sensor 171 and the damping of the crown 110. For example, the friction force sensed by the friction sensor 171 and the damping of the crown 110 may be in a one-to-one correspondence, or the friction force sensed by the friction sensor 171 and the damping of the crown 110 may be in a many-to-one correspondence, as illustrated below.

[0069] For example, the friction force sensed by the friction sensor 171 has multiple values, namely f1, f2, f3 and f4 from small to large. The damping of the crown 110 has multiple values, namely a1, a2, a3 and a4 from small to large. If the friction force sensed by the friction sensor 171 is f1, the current damping of the crown 110 is a1. If the friction force sensed by the friction sensor 171 is f2, the current damping of the crown 110 is a2. If the friction force sensed by the friction sensor 171 is f3, the current damping of the crown 110 is a3. If the friction force sensed by the friction sensor 171 is f4, the current damping of the crown 110 is a4.

[0070] Alternatively, the friction force sensed by the friction sensor 171 has multiple values, namely f1, f2, f3, f4 and f5 from small to large. The damping of the crown 110 has multiple values, namely a1, a2 and a3 from small to large. If the friction force sensed by the friction sensor 171 is f1 or f2, the current damping of the crown 110 is a1. If the friction force sensed by the friction sensor 171 is f3 or f4, the current damping of the crown 110 is a2. If the friction force sensed by the friction sensor 171 is f5, the current damping of the crown 110 is a3.

[0071] It is understood that the controller 160 is not limited to determining the current damping of the crown 110 according to the friction force sensed by the friction sensor 171 . The current damping of the crown 110 may be determined by the volume of the capsule 130 .

[0072] Figure 4b This is another control structure diagram of the crown module 100 provided in the embodiment of the present application. Figure 4bThe crown module 100 also includes a volume sensor 172, which is used to sense the current volume of the capsule 130. The controller 160 is used to determine the current damping of the crown 110 according to the current volume sensed by the volume sensor 172. Because the volume of the capsule 130 is different, the damping of the crown 110 is different, and the current damping of the crown 110 can be determined by obtaining the current volume of the capsule 130. The controller 160 then controls the adjustment structure 140 according to the relationship between the current damping and the target damping so that the damping of the crown 110 reaches the target damping.

[0073] In addition, the controller 160 determines the current damping of the crown 110 according to the current volume sensed by the volume sensor 172. When the shaft 120 does not rotate, the volume sensor 172 can also sense the current volume. In other words, even if the user does not apply torque to the shaft 120, the controller 160 can determine the current damping of the crown 110 according to the current volume sensed by the volume sensor 172.

[0074] Exemplarily, the controller 160 is configured to determine the current damping of the crown 110 according to the current volume sensed by the volume sensor 172, including:

[0075] Based on the current volume of the capsule 130 corresponding to the rotation of the shaft 120 being the first volume, the current damping is determined to be the third damping. Based on the current volume of the capsule 130 corresponding to the rotation of the shaft 120 being the second volume, the current damping is determined to be the fourth damping. The first volume is greater than the second volume, and the third damping is greater than the fourth damping.

[0076] Similar to the relationship between the friction force sensed by the friction sensor 171 and the damping of the crown 110, the embodiment of the present application does not limit the relationship between the current volume sensed by the volume sensor 172 and the damping of the crown 110. For example, the current volume sensed by the volume sensor 172 and the damping of the crown 110 can be a one-to-one correspondence or a many-to-one correspondence. The following is an example.

[0077] For example, the current volume sensed by the volume sensor 172 has multiple values, namely v1, v2, v3, and v4 from small to large. The damping of the crown 110 has multiple values, namely b1, b2, b3, and b4 from small to large. If the current volume sensed by the volume sensor 172 is v1, the current damping of the crown 110 is b1. If the current volume sensed by the volume sensor 172 is v2, the current damping of the crown 110 is b2. If the current volume sensed by the volume sensor 172 is v3, the current damping of the crown 110 is b3. If the current volume sensed by the volume sensor 172 is v4, the current damping of the crown 110 is b4.

[0078] Alternatively, the current volume sensed by the volume sensor 172 has multiple values, namely v1, v2, v3, v4, and v5, from small to large. The damping of the crown 110 has multiple values, namely b1, b2, and b3, from small to large. If the current volume sensed by the volume sensor 172 is v1 or v2, the current damping of the crown 110 is b1. If the current volume sensed by the volume sensor 172 is v3 or v4, the current damping of the crown 110 is b2. If the current volume sensed by the volume sensor 172 is v5, the current damping of the crown 110 is b3.

[0079] As mentioned above, if the current damping of the crown 110 is not equal to the target damping, the controller 160 controls the adjustment structure 140 to make the damping of the crown 110 reach the target damping. The embodiment of the present application does not limit the method of obtaining the target damping. For example, the user can input the target damping according to his or her own experience requirements when turning the crown 110. Alternatively, the controller 160 can obtain the rotation parameters of the shaft 120, and obtain the target damping after processing or analyzing the rotation parameters. The following are exemplary explanations.

[0080] Figure 5a This is another control structure diagram of the crown module 100 provided in the embodiment of the present application. Figure 5a The crown module 100 further includes a trigger 180, which is connected to the controller 160 by signal. The trigger 180 is used to input instructions and transmit the instructions to the controller 160, and the instructions are used to indicate the target damping. In this way, the user can input instructions indicating the target damping through the trigger 180 according to their own needs, so that the crown module 100 can achieve the user's desired experience.

[0081] The present embodiment of the present application does not limit the type of the trigger member 180. For example, the trigger member 180 may be a keyboard, or the trigger member 180 may be a sliding switch, or the trigger member 180 may be arranged on the display screen 12 (such as Figure 1a shown). Figure 5a In the example, the trigger member 180 is a sliding switch, and after sliding the trigger member 180, the target damping can be increased or decreased.

[0082] In some embodiments, the target damping may be determined by the controller 160 . Figure 5b This is another control structure diagram of the crown module 100 provided in the embodiment of the present application. Figure 5bThe crown module 100 also includes an acquisition device 190, which is signal-connected to the controller 160. The acquisition device 190 is used to acquire the rotation parameters of the shaft 120. The controller 160 is also used to: acquire the rotation parameters and determine the target damping based on the rotation parameters. In this way, the controller 160 can determine the target damping based on the rotation parameters when the shaft 120 rotates, and further control the adjustment structure 140 to make the damping of the crown 110 reach the target damping. Exemplarily, during the rotation of the shaft 120, the rotation parameters acquired by the acquisition device 190 change according to the rotation of the shaft 120, and the target damping is also updated accordingly, and the damping of the crown 110 can be adjusted in real time to reach the target damping.

[0083] In some embodiments, the rotation parameter includes: the angular acceleration of the rotating shaft 120. The acquisition device 190 includes an angular acceleration sensor 191, and the angular acceleration sensor 191 is used to sense the angular acceleration of the rotating shaft 120. The controller 160 is used to determine the target damping according to the angular acceleration sensed by the angular acceleration sensor 191, including: based on the angular acceleration being greater than or equal to zero, determining the target damping as the first damping; based on the angular acceleration being less than zero, determining the target damping as the second damping; the first damping is less than the second damping. In this way, the controller 160 determines the damping size according to the value of the angular acceleration sensed by the angular acceleration sensor 191. It can be understood that the first damping is less than the second damping, and the crown 110 with the first damping is relatively smoother than the crown 110 with the second damping. On the contrary, the crown 110 with the second damping is relatively more blocked than the crown 110 with the first damping.

[0084] When using the crown module 100, the user applies a torque to the crown 110, and the torque is transmitted to the shaft 120 to rotate the shaft 120 around the axis. The useful work done by the user on the shaft 120 is proportional to the difference between the torque and the maximum static friction of the shaft 120 and the angular acceleration of the shaft 120. Therefore, the angular acceleration of the shaft 120 is related to the torque applied to the crown 110 by the user.

[0085] If the angular acceleration is greater than or equal to zero, it means that the torque on the shaft 120 is greater than or equal to the maximum static friction of the shaft 120, the torque applied by the user to the crown 110 is large, and the user expects the shaft 120 to rotate quickly. At this time, the controller 160 determines the target damping to be the first damping, so that the crown 110 is relatively smoother, so as to meet the user's expectation of quickly rotating the shaft 120. If the angular acceleration is less than zero, it means that the force on the shaft 120 is less than the maximum static friction of the shaft 120, the force applied by the user to the crown 110 is small, and the user expects the shaft 120 to rotate slowly. At this time, the controller 160 determines the target damping to be the second damping, so that the crown 110 is relatively more retarded, so as to meet the user's expectation of slowly rotating the shaft 120.

[0086] Exemplarily, the user may wish to rotate the shaft 120 quickly or slowly, which can be determined based on the torque applied by the user to the crown 110. For example, the user may apply a larger torque to the crown 110 during coarse adjustment, so that the angular acceleration sensor 191 senses that the angular acceleration of the shaft 120 is greater than or equal to zero, and the controller 160 controls the damping of the crown 110 to be adjusted to a smaller second damping, so that the crown 110 is relatively smoother, the display-control ratio is increased, and the efficiency during coarse adjustment is improved. When coarse adjustment is completed and fine adjustment is required, the user may apply a smaller torque to the crown 110 during coarse adjustment, so that the angular acceleration sensor 191 senses that the angular acceleration of the shaft 120 is less than zero, so that the crown 110 is relatively blocked, the display-control ratio is reduced, and the accuracy of fine adjustment is improved. The crown module 100 is compatible with the interaction needs of different users in different usage scenarios, enhancing interaction efficiency and operating comfort.

[0087] The embodiment of the present application does not limit the type of the angular acceleration sensor 191 . For example, the angular acceleration sensor 191 is an optical sensor. The optical sensor can obtain the angular acceleration of the rotating shaft 120 in real time and transmit the information carrying the angular acceleration to the controller 160 .

[0088] In the embodiment where the angular acceleration sensor 191 is a light sensor, the light sensor is disposed on the base 150 . A cavity is provided between the rotating shaft 120 and the base 150 , and the light sensor is located in the cavity, which is conducive to the light sensor receiving light from the rotating shaft 120 .

[0089] It is understandable that the embodiment of the present application does not limit the functions of the electronic device 10. Therefore, there is no limit on the adjustment of the functions of the electronic device 10 by the crown module 100, and it can be set according to the usage scenario of the electronic device 10.

[0090] In a usage scenario of the crown module 100, the crown module 100 is used to adjust the electronic device 10 (such as Figure 1a The display screen 12 (as shown) Figure 1aFor example, the time displayed on the electronic device 10 that the user wants to locate is 08:30, and the current time displayed on the electronic device 10 is 08:00. The user hopes to position the time displayed on the electronic device 10 to near 08:30 in a shorter time; at this time, the user applies a larger torque to the crown 110, the angular acceleration sensor 191 senses that the angular acceleration of the shaft 120 is greater than zero, and the controller 160 controls the damping of the crown 110 to be adjusted to a smaller damping. At this time, the display control is relatively large, the screen displayed on the electronic device 10 changes rapidly, the adjustment efficiency is high, and the time displayed on the electronic device 10 is around 08:30. At this time, the user hopes to accurately adjust the time displayed on the electronic device 10 to 08:30 to avoid the screen displayed on the electronic device 10 changing rapidly and failing to accurately locate. The user applies a smaller torque to the crown 110, the angular acceleration sensor 191 senses that the angular acceleration of the shaft 120 is less than zero, and the controller 160 controls the damping of the crown 110 to be adjusted to a larger damping. At this time, the display control is relatively small, and the adjustment is more precise. In this way, the user's different demands for damping under different operating conditions can be met, improving interaction efficiency and comfort at the same time.

[0091] It is understandable that the use of the crown module 100 for adjusting the time displayed by the electronic device 10 is only an example. Figure 2 ) is an embodiment of AR glasses or VR glasses, in which the crown module 100 is used to adjust the brightness or resolution of the image in the AR glasses or VR glasses.

[0092] As described above, if the target damping is not equal to the current damping, the controller 160 controls the adjustment structure 140 to make the damping of the crown 110 reach the target damping. When the controller 160 determines that the target damping is the first damping, if the first damping is not equal to the current damping, the controller 160 controls the adjustment structure 140 to make the damping of the crown 110 the first damping. Similarly, when the controller 160 determines that the target damping is the second damping, if the second damping is not equal to the current damping, the controller 160 controls the adjustment structure 140 to make the damping of the crown 110 the second damping.

[0093] The embodiment of the present application does not limit the type of the first damping. In some embodiments, the first damping can be a range value, then the first damping is greater than or equal to the first value and less than or equal to the second value. For example, if the current damping is greater than or equal to the first value and less than or equal to the second value, the controller 160 controls the adjustment structure 140 not to change the damping. In other embodiments, the first damping is a point value. Similarly, in the embodiment where the second damping is a range value, the maximum value of the second damping is less than the minimum value of the first damping.

[0094] As described above, the controller 160 controls the adjustment structure 140 to adjust the volume of the capsule 130 so that the damping of the crown 110 reaches the target damping. Therefore, in some embodiments, the controller 160 needs to send an adjustment signal to the adjustment structure 140, and the adjustment signal carries the volume of the capsule 130.

[0095] The embodiment of the present application does not limit the type of the controller 160. Figure 5b As shown, the controller 160 may include a processor 161 and a signal generator 162. The processor 161 may be connected to the signal generator 162 by signal. The processor 161 may be connected to the angular acceleration sensor 191 by signal, and the signal generator 162 may be connected to the adjustment structure 140 by signal. The processor 161 is used to obtain the target damping according to the rotation parameter, determine the target volume of the capsule 130 corresponding to the target damping, and send a control signal including the parameter of the target volume to the signal generator 162. The signal generator 162 is used to generate an adjustment signal for adjusting the volume of the capsule 130 according to the control signal, and send it to the adjustment structure 140. In this way, the controller 160 converts the rotation parameter into an adjustment signal for adjusting the volume of the capsule 130, and the adjustment structure 140 adjusts the volume of the capsule 130 to the target volume after receiving the adjustment signal.

[0096] For example, Figure 6 This is a schematic diagram of the process of adjusting the damping of the crown 110 provided in the embodiment of the present application. Figure 6 , the user can rotate the crown 110. When the crown 110 rotates, the interface of the display screen 12 can change. The angular acceleration sensor 191 can sense the rotation parameters of the shaft 120. The processor 161 can receive the rotation parameters to obtain the target damping, and can determine the target volume of the capsule 130 corresponding to the target damping, and can send a control signal including the parameters of the target volume to the signal generator 162. The signal generator 162 can receive the control signal sent by the processor 161, and can generate an adjustment signal for adjusting the volume of the capsule 130. The signal generator 162 can send the adjustment signal to the adjustment capsule 130, and the adjustment structure 140 can adjust the volume of the capsule 130 to the target volume after receiving the adjustment signal. Since the damping of the crown 110 changes, the interface of the display screen 12 changes after the user rotates the crown 110. Because the damping changes, the ratio of the interface change of the display screen 12 to the rotation arc length of the user rotating the crown 110 changes, which can improve the user experience.

[0097] The regulating structure 140 includes an air pump 141 (such as Figure 3a In the example shown in FIG. 1 , the signal generator 162 may send an adjustment signal for adjusting the volume of the capsule 130 to the air pump 141, and the air pump 141 may output gas into the capsule 130 or exhaust gas to make the volume of the capsule 130 the target volume.

[0098] Similarly, the adjustment structure 140 includes a liquid pump 142 (such as Figure 3b In the example shown in FIG. 1 , the signal generator 162 may send an adjustment signal for adjusting the volume of the capsule 130 to the liquid pump 142, and the liquid pump 142 may output gas into the capsule 130 or discharge liquid so that the volume of the capsule 130 is the target volume.

[0099] Exemplarily, the processor 161 includes a SOC (system-on-a-chip) chip. The signal generator 162 includes a PWM (pulse width modulation) wave generator. The SOC chip and the PWM wave generator are connected via a circuit. In an embodiment where the rotation parameter is angular acceleration, the SOC chip receives information about the angular acceleration and generates an adjustment signal for adjusting the volume of the capsule 130 corresponding to the angular acceleration. The PWM wave generator generates a pulse signal for adjusting the volume of the capsule 130, so that the adjustment structure 140 adjusts the volume of the capsule 130 to the target volume. For example, when the adjustment structure 140 includes an air pump 141 (such as Figure 3a In the example shown in FIG. 1 , if the target volume is greater than the current volume, the PWM wave generator generates a pulse signal to control the air pump 141 to pump air into the air storage space 131 (such as Figure 3a If the target volume is smaller than the current volume, the PWM wave generator generates a pulse signal to control the air pump 141 to discharge the gas in the air storage space 131. The regulating structure 140 includes a liquid pump 142 (as shown in FIG. Figure 3b The same is true for the example shown in FIG. 1 , which will not be repeated here.

[0100] The present application embodiment does not limit the control method of the crown module 100. Figure 5b The control method of the crown module 100 shown is described as an example.

[0101] Figure 7 This is a control flow chart of a crown module 100 provided in an embodiment of the present application. Figure 7 , the control method of the crown module 100 includes:

[0102] S10 . Obtain the rotation parameters of the rotating shaft 120 .

[0103] For example, the rotation parameters of the rotating shaft 120 may be obtained by the obtaining device 190. The present application embodiment does not limit the method for executing S10. The setting is performed according to the rotation parameters.

[0104] In some embodiments, the rotation parameter includes: the angular acceleration of the rotating shaft 120. The acquisition device 190 includes an angular acceleration sensor 191, and the angular acceleration sensor 191 is used to sense the angular acceleration of the rotating shaft 120. Exemplarily, the angular acceleration sensor 191 is a light sensor.

[0105] When using the crown module 100, the user applies a torque to the crown 110, and the torque is transmitted to the shaft 120 to rotate the shaft 120 around the axis. The arc of rotation of the shaft 120 is related to the adjustment amount of the shaft 120. As mentioned above, the arc of rotation of the shaft 120 is related to the useful work done by the user on the crown 110. The useful work is related to the torque and the maximum static friction of the shaft 120. The difference between the useful work, the torque and the maximum static friction of the shaft 120 is proportional to the angular acceleration of the shaft 120. Therefore, the angular acceleration of the shaft 120 is related to the torque applied by the user to the crown 110. Therefore, sensing the angular acceleration of the shaft 120 is conducive to confirming the magnitude of the torque applied by the user to the crown 110, and the magnitude of the applied torque can determine the user's intention. For example, if the torque is large, the user wants the shaft 120 to rotate quickly; if the torque is small, the user wants the shaft 120 to rotate slowly.

[0106] S20. Determine the damping of the crown 110 as the target damping according to the rotation parameters.

[0107] Since the damping of the crown 110 has multiple values, the target damping is determined according to the rotation parameters. The target damping is the damping that meets the user's current needs, so as to facilitate subsequent adjustment of the damping of the crown 110.

[0108] Exemplarily, in an embodiment where the rotation parameter includes the angular acceleration of the rotation axis; S20 includes:

[0109] Based on the angular acceleration being greater than or equal to zero, the target damping is determined to be the first damping; based on the angular acceleration being less than zero, the target damping is determined to be the second damping; the first damping is less than the second damping.

[0110] By determining the target damping according to the angular acceleration, the magnitude of the torque received by the shaft can be known relatively accurately, providing a basis for subsequently adjusting the damping of the crown to an appropriate damping so that the crown module 100 has an appropriate display-control ratio.

[0111] S30. Control the adjustment structure 140 to make the damping of the crown 110 reach the target damping.

[0112] By adjusting the damping of the crown 110 to the target damping, the crown module 100 can have a suitable display-control ratio, providing the user with an excellent experience.

[0113] In some embodiments, S30 includes: the controller 160 adjusts the volume of the capsule 130 so that the damping of the crown 110 reaches the target damping. If the volume of the capsule 130 increases, the contact area between the shaft 120 and the capsule 130 increases when the shaft 120 rotates, the maximum static friction force during the relative motion of the shaft 120 and the capsule 130 increases, and the damping of the shaft 120 increases. Conversely, if the volume of the capsule 130 decreases, the damping of the shaft 120 decreases. The crown 110 and the shaft 120 are connected, and the damping of the crown 110 and the shaft 120 are the same.

[0114] The control method of the crown module provided in the embodiment of the present application can control the damping of the crown module to the target damping according to the rotation parameters of the shaft, so that the crown module in the target damping state is more adapted to the current state of the shaft. For example, when high interaction efficiency is required, the target damping is reduced and the display-control ratio is increased. When precise adjustment is required, the target damping is increased and the display-control ratio is reduced, which is conducive to fine adjustment.

[0115] The embodiment of the present application also provides a computer-readable storage medium. The computer-readable storage medium can be any available medium that can be stored by a computing device or a data storage device such as a data center containing one or more available media. The available medium can be a magnetic medium (e.g., a floppy disk, a hard disk, a tape), an optical medium (e.g., a DVD), or a semiconductor medium (e.g., a solid-state hard disk). The computer-readable storage medium includes instructions that instruct the computing device to execute the airbag control method, or instruct the computing device to execute the airbag control method.

[0116] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
