On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0042] In daily life, in order to facilitate the control of the working status of some electrical equipment, push-buttons that are easy for users to operate are generally set. For example, the user presses a button to trigger the relevant control instructions for controlling the electrical equipment. With the development of intelligent electrical equipment, the corresponding control instructions are gradually increasing. The more common method at present is to associate a control instruction with each push-button, and to meet the control needs by integrating multiple push-buttons.

[0043] However, the installation area occupied by multiple keys is large, and the integrated key device has a complex structure due to the large number of keys, which is not conducive to the miniaturization of the product.

[0044] Based on the above technical problems, an embodiment of the present invention is proposed. The embodiment of the present invention may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5 and a second switch 6. The housing 1 has an installation cavity 101, the rotating body 2 is embedded in the installation cavity 101, and has a through hole 201. The pressing member 3 is embedded in the through hole 201, the elastic component 4 is located in the installation cavity 101, and is connected to the end of the rotating body 2, wherein the elastic component 4 is in contact with the end of the pressing member 3. The first switch component 5 is arranged in the installation cavity 101 and is in contact with the elastic component 4. When the rotating body 2 rotates, it drives the elastic component 4 to press different positions on the first switch component 5 and output different first switch signals. The second switch 6 is located at the center of the first switch component 5 and is in contact with the elastic component 4. When the pressing member 3 is pressed, the elastic component 4 presses the second switch 6 and outputs a second switch signal. Therefore, different switch signals associated with different control instructions can be generated by rotating the rotating body 2 or pressing the pressing member 3 in different combinations. This can reduce the number and volume of buttons and reduce the structural complexity of the button device while meeting the control requirements.

[0045] Reference Figure 1-8The embodiment of the present invention provides a key device, which may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, and a second switch 6. The housing 1 has an installation cavity 101, the rotating body 2 is embedded in the installation cavity 101, and has a through hole 201. The pressing member 3 is embedded in the through hole 201, the elastic component 4 is located in the installation cavity 101, and is connected to the end of the rotating body 2, wherein the elastic component 4 is in contact with the end of the pressing member 3. The first switch component 5 is arranged in the installation cavity 101 and is in contact with the elastic component 4. When the rotating body 2 rotates, the elastic component 4 is driven to press different positions on the first switch component 5 and output different first switch signals. The second switch 6 is located at the center of the first switch component 5 and is in contact with the elastic component 4. When the pressing member 3 is pressed, the elastic component 4 presses the second switch 6 and outputs a second switch signal.

[0046] In an embodiment of the present invention, the button device may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, and a second switch 6. The housing 1 is provided with an installation cavity 101, and the rotating body 2, the pressing member 3, the elastic component 4, the first switch component 5, and the second switch 6 are all installed in the installation cavity 101 of the housing 1. The rotating body 2 is embedded in the installation cavity 101 and is loosely matched with the housing 1. The cross-sectional shape of the rotating body 2 along its radial direction is circular, so that the rotating body 2 can rotate in the installation cavity 101 when the rotating body 2 is screwed. A portion of the rotating body 2 extends outside the installation cavity 101, so that it is convenient for the user to screw the rotating body 2.

[0047] The rotating body 2 is provided with a through hole 201, and the pressing member 3 is embedded in the through hole 201 and has a clearance fit with the rotating body 2. In some embodiments, the through hole 201 is arranged to penetrate along the central axis of the rotating body 2, and the radial cross-section of the through hole 201 along the rotating body 2 is circular, and the pressing member 3 is embedded in the through hole 201 and does not affect the rotation of the rotating body 2.

[0048] The elastic component 4 is located in the mounting cavity 101 and is connected to the end of the rotating body 2. The elastic component 4 is also in contact with the end of the pressing member 3. The first switch component 5 and the second switch 6 are in contact with the elastic component 4 respectively. The second switch 6 is located at the center of the first switch component 5. In other words, the end surface of the elastic component 4 close to the rotating body 2 is connected to the rotating body 2 and is in contact with the pressing member 3. The end surface of the elastic component 4 close to the first switch component 5 is in contact with the first switch component 5 and the second switch 6 respectively.

[0049] When the rotating body 2 rotates under the action of the screwing force, the rotating body 2 drives the elastic component 4 to rotate synchronously, so that different first switch signals are output by pressing different positions on the first switch component 5. Therefore, different control instructions can be associated with different first switch signals generated by the rotating body 2, or combinations of different first switch signals.

[0050] When the pressing member 3 is pressed, the pressing member 3 increases the contact pressure on the elastic component 4, so that the second switch 6 can be pressed and touched, triggering the second switch 6 to output a second switch signal. For another example, different control instructions can be associated with the number of consecutive presses of the second switch 6. Thus, different switch signals can be formed to associate with different control instructions through the rotation of the rotating body 2 or different combinations of pressing the pressing member 3, thereby reducing the number and volume of buttons and reducing the structural complexity of the button device on the basis of meeting the control requirements.

[0051] In summary, the embodiment of the present invention discloses a key device, which may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, and a second switch 6. The housing 1 has an installation cavity 101, the rotating body 2 is embedded in the installation cavity 101, and has a through hole 201. The pressing member 3 is embedded in the through hole 201, the elastic component 4 is located in the installation cavity 101, and is connected to the end of the rotating body 2, wherein the elastic component 4 is in contact with the end of the pressing member 3. The first switch component 5 is arranged in the installation cavity 101 and is in contact with the elastic component 4. When the rotating body 2 rotates, the elastic component 4 is driven to press different positions on the first switch component 5 and output different first switch signals. The second switch 6 is located at the center of the first switch component 5 and is in contact with the elastic component 4. When the pressing member 3 is pressed, the elastic component 4 presses the second switch 6 and outputs a second switch signal. Therefore, different switch signals associated with different control instructions can be generated by rotating the rotating body 2 or pressing the pressing member 3 in different combinations. This can reduce the number and volume of buttons and reduce the structural complexity of the button device while meeting the control requirements.

[0052] An optional embodiment of the invention, referring to Figure 1 , Figure 4 , Figure 5 as well as Figure 6As shown, the key device may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, a second switch 6 and a ring member 7. The housing 1 has an installation cavity 101, the rotating body 2 is embedded in the installation cavity 101, and has a through hole 201. The pressing member 3 is embedded in the through hole 201, the elastic component 4 is located in the installation cavity 101, and is connected to the end of the rotating body 2, wherein the elastic component 4 is in contact with the end of the pressing member 3. The first switch component 5 is arranged in the installation cavity 101 and is in contact with the elastic component 4. When the rotating body 2 rotates, the elastic component 4 is driven to press different positions on the first switch component 5 and output different first switch signals. The second switch 6 is located at the center of the first switch component 5 and is in contact with the elastic component 4. When the pressing member 3 is pressed, the elastic component 4 presses the second switch 6 and outputs a second switch signal. The annular member 7 is fixed in the housing 1 and is located on the outer surface of the rotating body 2, wherein the annular member 7 is provided with a protrusion 71 inwardly along the radial direction of the rotating body 2. The rotating body 2 further comprises a body 21 and a plurality of latch teeth 22, wherein the plurality of latch teeth 22 are distributed around the circumference of the body 21 and are extended along the axial direction of the body 21, and the protrusion 71 is engaged with the latch teeth 22 to form a toggling tactile sensation of the rotating body 2.

[0053] In an embodiment of the present invention, the button device may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, a second switch 6, and a ring 7. The housing 1 is provided with an installation cavity 101, and the rotating body 2, the pressing member 3, the elastic component 4, the first switch component 5, and the second switch 6 are all installed in the installation cavity 101 of the housing 1. The rotating body 2 is embedded in the installation cavity 101 and has a clearance fit with the housing 1. The cross-sectional shape of the rotating body 2 along its radial direction is circular, so that the rotating body 2 can rotate in the installation cavity 101 when the rotating body 2 is screwed. A portion of the rotating body 2 extends outside the installation cavity 101, so that it is convenient for the user to screw the rotating body 2.

[0054] The rotating body 2 is provided with a through hole 201, and the pressing member 3 is embedded in the through hole 201 and has a clearance fit with the rotating body 2. In some embodiments, the through hole 201 is arranged to penetrate along the central axis of the rotating body 2, and the radial cross-section of the through hole 201 along the rotating body 2 is circular, and the pressing member 3 is embedded in the through hole 201 and does not affect the rotation of the rotating body 2.

[0055] The elastic component 4 is located in the mounting cavity 101 and is connected to the end of the rotating body 2. The elastic component 4 is also in contact with the end of the pressing member 3. The first switch component 5 and the second switch 6 are in contact with the elastic component 4 respectively. The second switch 6 is located at the center of the first switch component 5. In other words, the end surface of the elastic component 4 close to the rotating body 2 is connected to the rotating body 2 and is in contact with the pressing member 3. The end surface of the elastic component 4 close to the first switch component 5 is in contact with the first switch component 5 and the second switch 6 respectively.

[0056] When the rotating body 2 rotates under the action of the screwing force, the rotating body 2 drives the elastic component 4 to rotate synchronously, so that different first switch signals are output by pressing different positions on the first switch component 5. Therefore, different control instructions can be associated with different first switch signals generated by the rotating body 2, or combinations of different first switch signals.

[0057] When the pressing member 3 is pressed, the pressing member 3 increases the contact pressure on the elastic component 4, so that the second switch 6 can be pressed and touched, triggering the second switch 6 to output a second switch signal. For another example, different control instructions can be associated with the number of consecutive presses of the second switch 6. Thus, different switch signals can be formed to associate with different control instructions through the rotation of the rotating body 2 or different combinations of pressing the pressing member 3, thereby reducing the number and volume of buttons and reducing the structural complexity of the button device on the basis of meeting the control requirements.

[0058] The annular member 7 is fixed in the housing 1 and is located on the outer surface (also referred to as the outer circumference) of the rotating body 2. The annular member 7 is provided with a protrusion 71 inwardly along the radial direction of the rotating body 2. For example, the annular member 7 can be made of steel material, and the annular member 7 and the protrusion 71 are an integrated structure.

[0059] The latch teeth 22 may be an integral structure with the rotating body 2, wherein a plurality of the latch teeth 22 are distributed around the circumference of the main body 21. For example, the main body 21 may be circular along its radial cross-section, and the circumferential distribution may be an equal-angle distribution with the central axis of the main body 21 as the center line. The latch teeth 22 are arranged to extend along the axial direction of the main body 21, thereby the protrusion 71 and the latch teeth 22 are meshed in the radial direction of the main body 21. During the rotation of the rotating body 2, the latch teeth 22 rotate synchronously, and when each of the latch teeth 22 passes through the protrusion 71, a large screwing force is required to release the meshing relationship, and the user can feel obvious resistance when screwing the rotating body 2, thereby forming a toggling touch of the rotating body 2. According to the matching relationship between the latch teeth 22 and the protrusion 71, the pressure contact position of the elastic component 4 on the first switch component 5 can be distinguished, so that different first switch signals can be output.

[0060] An optional embodiment of the invention, referring to Figure 1 , Figure 5 as well as Figure 7 As shown, the rotating body 2 may include a limiting portion 23, which is located on the end of the main body 21 close to the first switch assembly 5 and extends radially along the main body 21. The elastic component 4 includes a compression spring 41, which is located between the main body 21 and the first switch assembly 5 and is fixedly connected to the limiting portion 23, so that the position between the rotating body 2 and the housing 1 is limited by the cooperation between the compression spring 41 and the limiting portion 23.

[0061] In the embodiment of the present invention, the rotating body 2 includes a limiting portion 23, which is disposed on the end of the main body 21 close to the first switch assembly 5 and extends radially along the main body 21. In other words, the radial diameter of the limiting portion 23 is greater than the radial diameter of the main body 21, so that the limiting portion 23 and the housing 1 can form a surface contact along the radial direction of the main body 21. Therefore, under the action of the limiting portion 23, the rotating body 2 will not fall off from the mounting cavity 101.

[0062] The elastic component 4 may include a compression spring 41, and the compression spring 41 is located between the rotating body 2 and the first switch 51. For example, one end face of the compression spring 41 may be fixedly connected to the end face of the rotating body 2, and the other end face of the compression spring 41 may form a pressure contact with the first switch component 5. Thus, the deformation pressure of the compression spring 41 may be applied to the rotating body 2 to prevent the rotating body 2 from being axially offset toward the first switch component 5. The relative position between the rotating body 2 and the housing 1 may be limited by the cooperation of the compression spring 41 and the limiting portion 23.

[0063] In some optional embodiments, the rotating body 2 can be made of plastic material, which refers to a material that is processed and formed by adding fillers, plasticizers, lubricants, stabilizers and other auxiliary materials to high molecular compounds such as thermoplastic resins or thermosetting resins. It has the plasticity and formability of plastics, and also has the elasticity and flexibility of rubber. The rotating body 2 made of plastic material has a certain structural strength and elasticity. In addition, the compression spring 41 can be fixed to the rotating body 2 by hot melting. For example, the rotating body 2 also includes a hot melt column, the compression spring 41 is sleeved on the hot melt column, and the hot melt column is melted by a hot melt head. Under the pressure of the hot melt head, the melted part of the hot melt column adheres to the surface of the compression spring 41, and the compression spring 41 is fixed by hot melting after cooling.

[0064] In some optional embodiments, in order to improve the processing efficiency of the rotating body 2 and reduce the production cost of the rotating body 2, the main body 21, the latching teeth 22 and the limiting portion 23 may be an integrated structure. Correspondingly, the hot melt column and the rotating body 2 may also be an integrated structure.

[0065] In an optional embodiment of the invention, referring to Figure 5 As shown, a limiting edge 8 is also provided in the installation cavity 101 of the housing 1, and a limiting groove 202 is provided on the outer surface of the rotating body 2. The position between the rotating body 2 and the housing 1 is limited by the shape cooperation between the limiting edge 8 and the limiting groove 202.

[0066] In the embodiment of the present invention, the limiting edge 8 and the housing 1 may be an integral structure, and a limiting groove 202 is provided on the outer surface of the rotating body 2, so that the relative position of the rotating body 2 and the housing 1 can be limited by the shape matching of the limiting edge 8 and the limiting groove 202, such as clearance matching, so that the rotating body 2 will not be axially offset during the rotation process.

[0067] In some optional embodiments, in order to facilitate the assembly of the various components described in the above invention embodiments, the housing 1 can adopt a split structure design. Those skilled in the art can determine the specific structure of the housing 1 according to actual design requirements, and no further limitations are made here.

[0068] An optional embodiment of the invention, referring to Figure 1 and Figure 4 As shown, the elastic component 4 also includes an elastic sheet 42, which is located between the pressing member 3 and the second switch 6, and the elastic sheet 42 is fixedly connected to the second switch 6, so that when the pressing member 3 is pressed, the elastic sheet 42 presses the second switch 6 to output a second switch signal.

[0069] In an embodiment of the present invention, the elastic component 4 may further include an elastic sheet 42. For example, the elastic sheet 42 may include but is not limited to a corrugated steel sheet, etc. The elastic sheet 42 may be fixed on the second switch 6, so that when the pressing member 3 is pressed hard, the pressing force on the elastic sheet 42 is increased by the pressing member 3, so that the second switch 6 is triggered and the second switch signal corresponding to the second switch 6 is output.

[0070] An optional embodiment of the invention, referring to Figure 6 As shown, the button device further includes a clamping portion 9 , which is disposed in the mounting cavity 101 of the housing 1 , and the clamping portion 9 is clamped with the annular member 7 to fix the annular member 7 .

[0071] In the embodiment of the present invention, the key device may further include a clamping portion 9, which is disposed in the mounting cavity 101 of the housing 1, wherein the clamping portion 9 cooperates with the housing 1 to form a clamping groove with an opening facing the axial direction of the rotating body 2, and the ring member 7 can be firmly clamped on the housing 1 by assembling the ring member 7 from the opening to the clamping groove along the axial direction of the rotating body 2, and there is a certain interval between the clamping portion 9 and the clamping teeth 22 in the radial direction of the rotating body 2. Thus, the rotation of the rotating body 2 can be unaffected.

[0072] In some embodiments, the clamping portion 9 and the housing 1 may be an integrated structure. In other embodiments, in order to improve the structural stability of the annular member 7, the number of the clamping portions 9 may be at least two, and those skilled in the art may determine the specific number of clamping portions 9 based on actual test results. For example, the number of the clamping portions 9 may be 2, 3, or 4, etc., which is not limited here.

[0073] An optional embodiment of the invention, referring to Figure 1 , Figure 4as well as Figure 7 As shown, the button device may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5 and a second switch 6.

The first switch component 5 includes a plurality of first switches 51, wherein the plurality of first switches 51 are distributed at equal angles with the second switch 6 as the center.

[0074] When the rotating body 2 rotates, it drives the elastic component 4 to press different positions on the first switch component 5, and output different first switch signals. The second switch 6 is located at the center of the first switch component 5 and contacts the elastic component 4. When the pressing member 3 is pressed, the elastic component 4 presses the second switch 6 and outputs a second switch signal.

[0075] In an embodiment of the present invention, the button device may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, and a second switch 6. The housing 1 is provided with an installation cavity 101, and the rotating body 2, the pressing member 3, the elastic component 4, the first switch component 5, and the second switch 6 are all installed in the installation cavity 101 of the housing 1. The rotating body 2 is embedded in the installation cavity 101 and is loosely matched with the housing 1. The cross-sectional shape of the rotating body 2 along its radial direction is circular, so that the rotating body 2 can rotate in the installation cavity 101 when the rotating body 2 is screwed. A portion of the rotating body 2 extends outside the installation cavity 101, so that it is convenient for the user to screw the rotating body 2.

[0076] The rotating body 2 is provided with a through hole 201, and the pressing member 3 is embedded in the through hole 201 and has a clearance fit with the rotating body 2. In some embodiments, the through hole 201 is arranged to penetrate along the central axis of the rotating body 2, and the radial cross-section of the through hole 201 along the rotating body 2 is circular, and the pressing member 3 is embedded in the through hole 201 and does not affect the rotation of the rotating body 2.

[0077] The elastic component 4 is located in the mounting cavity 101 and is connected to the end of the rotating body 2. The elastic component 4 is also in contact with the end of the pressing member 3. The first switch component 5 and the second switch 6 are in contact with the elastic component 4 respectively. The second switch 6 is located at the center of the first switch component 5. In other words, the end surface of the elastic component 4 close to the rotating body 2 is connected to the rotating body 2 and is in contact with the pressing member 3. The end surface of the elastic component 4 close to the first switch component 5 is in contact with the first switch component 5 and the second switch 6 respectively.

[0078] The first switch assembly 5 may include a plurality of first switches 51, wherein the plurality of first switches 51 are distributed at equal angles with the second switch 6 as the center. The first switch 51 may be a patch button switch, or a touch switch, etc. Those skilled in the art may determine the specific type of the first switch 51 according to actual design requirements, and no further limitation is made here. When the rotating body 2 rotates under the action of the twisting force, the rotating body 2 drives the elastic component 4 to rotate synchronously, thereby outputting different first switch signals by pressing different positions (that is, different first switches 51) on the first switch assembly 5. Thus, different control instructions can be associated with different first switch signals rotated out by the rotating body 2, or with a combination of different first switch signals.

[0079] In some embodiments, in order to improve the structural stability of the compression spring 41, it is usually necessary to form two-point pressure contact with the first switch component 5, for example, the compression spring 41 and the two pressure contact points formed on the first switch component 5 are in the same straight line. Thus, the control instructions corresponding to the two first switches 51 in the same straight line can be consistent.

[0080] For example, when the number of the first switches 51 is 2N, when the rotation of the rotating body 2 drives the compression spring 41 to form pressure contact with different first switches 51, N different first switch signals can be output.

[0081] In some embodiments, different first switches 51 may correspond to different numbers. Figure 8As shown, when the number of the first switches 51 is 12, a digital password between 1 and 6 can be set accordingly. When the first and seventh first switches 51 are pressed, it corresponds to the user inputting a password number "1". When the second and eighth first switches 51 are pressed, it corresponds to the user inputting a password number "2". When the third and ninth first switches 51 are pressed, it corresponds to the user inputting a password number "3". When the fourth and tenth first switches 51 are pressed, it corresponds to the user inputting a password number "4". When the fifth and eleventh first switches 51 are pressed, it corresponds to the user inputting a password number "5". When the sixth and twelfth first switches 51 are pressed, it corresponds to the user inputting a password number "6".

[0082] In other embodiments, different first switches 51 may correspond to different functional instructions. For example, when the first first switch 51 and the seventh first switch 51 are pressed, the corresponding control instruction is to turn on the fan; when the second first switch 51 and the eighth first switch 51 are pressed, the corresponding control instruction is to turn on the motor, etc.

[0083] When the pressing member 3 is pressed, the pressing member 3 increases the contact pressure on the elastic component 4, so that the second switch 6 can be pressed and touched, triggering the second switch 6 to output the second switch signal. For another example, different control instructions can be associated with the number of consecutive presses of the second switch 6. For example, if the second switch 6 is pressed once, the corresponding control instruction may be confirmation, and if the second switch 6 is pressed twice in a row, the corresponding control instruction may be cancellation, etc.

[0084] Therefore, different switch signals associated with different control instructions can be generated by rotating the rotating body 2 or pressing the pressing member 3 in different combinations. This can reduce the number and volume of buttons and reduce the structural complexity of the button device while meeting the control requirements.

[0085] In an optional embodiment of the invention, the number of the latch teeth 22 is consistent with the number of the first switches 51 .

[0086] In the embodiment of the present invention, when the user rotates the rotating body 2, the latch teeth 22 and the ring member 7 are in meshing contact, and correspondingly, the compression spring 41 forms a pressure contact with the first switch 51, thereby outputting a first switch signal corresponding to the first switch 51. Therefore, when the user feels the toggle touch, it is determined that the compression spring 41 forms a pressure contact with the first switch 51. Therefore, the number of the first switches 51 is consistent with the number of the latch teeth 22.

[0087] An optional embodiment of the invention, referring to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the button device further includes a circuit board 10, and the circuit board 10 is fixedly connected to the housing 1 and is electrically connected to the first switch assembly 5 and the second switch 6 respectively.

[0088] In the embodiment of the present invention, the key device may further include a circuit board 10, and the circuit board 10 is fixedly connected to the housing 1. For example, the circuit board 10 is fixed to the outer surface of the housing 1 to form a structural support for the housing 1 and other components. The circuit board 10 is electrically connected to the first switch component 5 and is electrically connected to the second switch 6, so that the first switch signal of the first switch component 5 and the second switch signal of the second switch 6 can be received.

[0089] An optional embodiment of the invention, referring to Figure 3 and Figure 4 As shown, the button device further includes a display screen 11 , which is embedded on the end surface of the pressing member 3 and is communicatively connected with the circuit board 10 .

[0090] In the embodiment of the present invention, the display screen 11 may be embedded in the end surface of the pressing member 3 away from the elastic component 4. For example, the display screen 11 may be snap-fitted with the pressing member 3, and the display screen 11 may be powered by a button battery. The display screen 11 may be connected to the circuit board 10 through a WIFI module or a Bluetooth module, so that the first switch signal and the second switch signal received by the circuit board 10 may be input to the display screen 11 for display.

[0091] Different first switches 51 can correspond to different numbers. For example, when the number of the first switches 51 is 12, a digital password between 1 and 6 can be set accordingly. When the first first switch 51 and the seventh first switch 51 are pressed, it corresponds to the user inputting the password number "1". When the second first switch 51 and the eighth first switch 51 are pressed, it corresponds to the user inputting the password number "2". When the third first switch 51 and the ninth first switch 51 are pressed, it corresponds to the user inputting the password number "3". When the fourth first switch 51 and the tenth first switch 51 are pressed, it corresponds to the user inputting the password number "4". When the fifth first switch 51 and the eleventh first switch 51 are pressed, it corresponds to the user inputting the password number "5". When the sixth first switch 51 and the twelfth first switch 51 are pressed, it corresponds to the user inputting the password number "6".

[0092] For example, when the user rotates the rotating body 2, presses the first first switch 51, and determines to input the password "1", the user can choose to press the pressing member 3 once to press the second switch 6 to determine to input the password "1". When the control panel receives the first switch signal corresponding to the password "1", it can transmit the corresponding first switch signal to the display screen 11, so that it is displayed on the display screen 11. Alternatively, the user can also choose to press the pressing member 3 twice in a row to press the second switch 6 twice to determine to cancel the input of the password "1". Rotate the rotating body 2 again, press the other first switches 51, and re-enter the new password. When the control panel receives the first switch signal corresponding to other digital passwords, it can transmit the corresponding first switch signal to the display screen 11, so that other digital passwords that the user wants to input are displayed on the display screen 11. Therefore, based on the combination of the pressing member 3 and the rotating body 2, the input of different passwords of the key device can be realized.

[0093] For another example, different first switches 51 can correspond to different functional instructions. For example, when the first first switch 51 and the seventh first switch 51 are pressed, the corresponding control instruction is to turn on the fan; when the second first switch 51 and the eighth first switch 51 are pressed, the corresponding control instruction is to turn on the motor, etc.

[0094] When the user rotates the rotating body 2 and presses the first first switch 51 to determine the input control instruction "turn on the fan", the user can choose to press the pressing member 3 once to press the second switch 6 to determine the input control instruction "turn on the fan". When the control board receives the first switch signal corresponding to the control instruction "turn on the fan", it can transmit the corresponding first switch signal to the display screen 11, so as to display it on the display screen 11. Alternatively, the user can also choose to press the pressing member 3 twice in a row to press the second switch 6 twice to determine to cancel the input control instruction "turn on the fan". After determining the input control instruction "turn on the fan", the circuit board 10 can drive the fan.

[0095] Therefore, the key device described in the embodiment of the present invention can be applied to devices with many control instructions, or devices that require password instruction input, such as electronic password locks and other devices.

[0096] In summary, the embodiment of the present invention discloses a key device, which may include a housing 1, a rotating body 2, a pressing member 3, an elastic component 4, a first switch component 5, and a second switch 6. The housing 1 has an installation cavity 101, the rotating body 2 is embedded in the installation cavity 101, and has a through hole 201. The pressing member 3 is embedded in the through hole 201, the elastic component 4 is located in the installation cavity 101, and is connected to the end of the rotating body 2, wherein the elastic component 4 is in contact with the end of the pressing member 3. The first switch component 5 is arranged in the installation cavity 101 and is in contact with the elastic component 4. When the rotating body 2 rotates, the elastic component 4 is driven to press different positions on the first switch component 5 and output different first switch signals. The second switch 6 is located at the center of the first switch component 5 and is in contact with the elastic component 4. When the pressing member 3 is pressed, the elastic component 4 presses the second switch 6 and outputs a second switch signal. Therefore, different switch signals associated with different control instructions can be generated by rotating the rotating body 2 or pressing the pressing member 3 in different combinations. This can reduce the number and volume of buttons and reduce the structural complexity of the button device while meeting the control requirements.
