For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0045] First, refer to Figure 1-Figure 7A multifunctional cabinet 100 according to an embodiment of the present invention is briefly described. The multifunctional cabinet 100 includes a control component 10 and a cabinet body 20 on which an integrated audio system 22 and a drawer 21 are installed. A lock is installed between the cabinet body 20 and the drawer 21. The control component 10 can be used to adjust the volume of the integrated audio system 22 and unlock the above-mentioned lock.

[0046] Reference below Figure 1-Figure 7 The control assembly 10 according to the first embodiment of the present invention is described below.

[0047] like Figure 1-Figure 7 As shown, a control assembly 10 according to an embodiment of the first aspect of the present invention includes a mounting plate 11, a fingerprint unlocker 13, a knob 12 that rotates with the mounting plate 11, and a rotary encoder 15 that outputs a signal based on the rotation angle of the knob 12. The knob 12 includes a handle 121 and a rotating shaft 122 coaxially connected. One end of the handle 121 is connected to the rotating shaft 122, and the other end is provided with the fingerprint unlocker 13. The knob 12 has a clearance hole 1201 extending along its axis. The fingerprint unlocker 13 is located within the clearance hole 1201. A cable for transmitting signals and supplying power to the fingerprint unlocker 13 is connected to the fingerprint unlocker 13. The cable of the fingerprint unlocker 13 passes through the clearance hole 1201 and extends through the knob 12. It should be understood that the cable can also be used only for transmitting signals or supplying power to the fingerprint unlocker 13. The rotary encoder 15 includes a fixed portion 152 fixedly connected to the mounting plate 11 and a rotating portion 151 connected to the knob 12. The rotating portion 151 of the rotary encoder 15 rotates synchronously with the knob 12.

[0048] In the control assembly 10 of this embodiment, the fingerprint unlocker 13 can be electrically connected to the lock via a cable, thereby issuing an unlock command to the lock when the fingerprint verification matches. The fingerprint unlocker 13 can also be electrically connected to a power source via a cable to obtain power. For example, after the fingerprint unlocker 13 recognizes the fingerprint information of a specific user, the lock can be unlocked according to the electrical signal transmitted from the fingerprint unlocker 13, allowing the drawer 21 to be opened.

[0049] The knob 12 rotates in conjunction with the mounting plate 11, and the rotary encoder 15 outputs a control signal according to the change in the rotation angle of the knob 12, so that the user can change the control signal output by the rotary encoder 15 by rotating the knob 12, thereby conveniently adjusting the volume of the integrated audio 22. For example, when the knob 12 and the rotary encoder 15 cooperate to adjust the volume of the integrated audio 22, the user can manually control the handle 121 of the knob 12 to rotate, so that the rotary encoder 15 outputs a corresponding control signal to the integrated audio 22 according to the rotation angle of the knob 12, thereby adjusting the volume of the integrated audio 22 in real time.

[0050] In this embodiment, the fingerprint unlocker 13 is arranged on the side of the handle 121 of the knob 12 facing away from the rotating shaft, which has good integration and allows the user to conveniently adjust the volume and unlock the lock at the knob. An avoidance hole 1201 is provided on the knob 12, and the avoidance hole 1201 passes through the axial direction of the knob 12. The structure is simple, which facilitates the installation of the fingerprint unlocker 13 and the cable connected to the fingerprint unlocker 13, making it more convenient and easy to assemble the control component 10 in the multi-function cabinet 100.

[0051] In this embodiment, the fingerprint unlocker 13 is arranged in the avoidance hole 1201 of the knob 12, and the fingerprint unlocker 13 and the knob 12 are integrated into the mounting plate 11, so that the user can more easily reach the fingerprint unlocker 13 and the knob 12 when in use, avoiding the user from operating at multiple positions of the multi-function cabinet 100, thereby facilitating user use.

[0052] In some embodiments of the present invention, an assembly hole 1101 for installing the knob 12 is provided on the mounting plate 11, and the fingerprint unlocker 13 is connected to the knob 12 and rotates synchronously with the knob 12. At this time, the cable connected to the fingerprint unlocker 13 is twisted to a certain extent as the fingerprint unlocker 13 rotates. When the rotation angle of the knob 12 is too large, for example, when the knob 12 is rotated clockwise for multiple turns, the cable is twisted excessively and breaks, causing the electrical connection between the fingerprint unlocker 13 and the lock to fail and the lock cannot be unlocked.

[0053] At the same time, when the cable is twisted, the cable has a certain obstruction and inhibition effect on the rotation of the knob 12, so that after the knob 12 is rotated to a certain angle, the knob 12 is reversed, thereby reducing the stability of the coordinated operation of the knob 12 and the rotary encoder 15.

[0054] In order to avoid the above-mentioned problems, a limit component is provided between the mounting plate 11 and the knob 12 to limit the rotation angle range of the knob 12, thereby stably and reliably preventing the knob 12 from rotating at an excessive angle, thereby effectively preventing the cable of the fingerprint unlocker 13 from being damaged due to excessive twisting, so that the fingerprint unlocker 13 can operate stably and reliably during the long-term use of the control component 10, and reduce the influence of the cable twisting on the use of the knob 12, so that the knob 12 can cooperate with the rotary encoder 15 to operate stably and reliably during the long-term use of the control component 10.

[0055] In some embodiments of the present invention, reference Figure 2As shown, the limiting assembly may include two parts respectively provided on the mounting plate 11 and the knob 12. The two parts of the limiting assembly are a limiting block 111 and a limiting groove (not shown in the figure) for inserting the limiting block 111. When the knob 12 and the mounting plate 11 rotate relative to each other, the limiting groove and the limiting block 111 rotate relative to each other around the rotating axis of the knob under the rotation of the knob.

[0056] In this embodiment, the limit block 111 is fixedly mounted on the mounting plate 11, and the limit groove is correspondingly formed on the knob 12. The limit block 111 is disposed on the knob 12, and the limit groove is correspondingly disposed on the mounting plate 11. In this embodiment, the limit groove and the limit block 111 can be arranged appropriately as needed. The limit groove limits the rotational displacement of the limit block 111. After the limit block 111 rotates a certain angle relative to the limit groove, the limit block 111 abuts against the inner wall of the limit groove and cannot continue to rotate, thereby limiting the rotation angle of the knob 12. The limit block 111 and the limit groove have a simple limiting structure and stable limiting.

[0057] When the limit block 111 and the limit slot rotate relative to each other around the rotation axis 122 of the knob 12, the limit slot has a margin for the relative rotation of the limit block 111, so that the knob 12 can have a certain rotation angle range, thereby meeting the use requirements of the knob 12. On the path of the limit block 111 rotating relative to the limit slot, the limit slot has a front stop wall located in front of the limit block 111 and a rear stop wall located behind the limit block 111, which limits the rotation range of the limit block 111 to between the front stop wall and the rear stop wall of the limit slot. As a result, when the fingerprint unlocker 13 rotates with the knob 12, the cable connected to the fingerprint unlocker 13 can maintain a low degree of twist, thereby making the operation of the control assembly 10 more stable and reliable during use.

[0058] Furthermore, the limiting groove can be configured to extend in an arc shape along the circumference of the knob 12, thereby ensuring that the limiting block 111 and the limiting groove can smoothly rotate relative to each other about the rotation axis 122 of the knob 12 after the limiting block 111 is inserted into the limiting groove. For example, the limiting block 111 can be configured to have an arc structure extending along the circumference of the knob 12, so that the limiting block 111 can better cooperate with the groove wall of the limiting groove to limit the position. The limiting block 111 can be a solid structure or can be composed of a plate rib or other structural form, as long as it meets the requirements of the limiting groove.

[0059] In some embodiments of the present invention, reference Figure 2 As shown, the rotating shaft 122 of the knob 12 can be inserted into the assembly hole 1101 , the handle 121 of the knob 12 is located outside the assembly hole 1101 , and the rotary encoder 15 is located on the side of the mounting plate 11 facing away from the handle 121 of the knob 12 .

[0060] The rotating shaft 122 of the knob 12 is inserted into the assembly hole 1101, and the handle 121 is outside the assembly hole 1101, which is convenient for user operation. The rotary encoder 15 is located on the side of the handle 121 of the mounting plate 11 facing away from the knob 12. The layout is reasonable and can meet the assembly requirements of the control component 10 in the multi-function cabinet 100.

[0061] In some embodiments of the present invention, the two ends of the assembly hole 1101 can be respectively defined as a first end and a second end for inserting the knob 12. The first end of the assembly hole 1101 is provided with a bracket for mounting the rotary encoder 15 (not shown in the figure), the fixed part 152 of the rotary encoder 15 is connected to the bracket, and the rotating part 151 of the rotary encoder 15 is connected to the rotating shaft 122 of the knob 12 and rotates synchronously with the knob 12.

[0062] In this embodiment, the mounting plate 11 is provided with an assembly hole 1101, and the assembly hole 1101 includes a first end and a second end. The knob 12 is inserted into the assembly hole 1101 from the second end and assembled with the mounting plate 11. The mounting plate 11 is provided with a bracket at the first end of the assembly hole 1101 to install the rotary encoder 15. The structure is simple, which facilitates the assembly and fixation of the rotary encoder 15. The fixing portion 152 of the rotary encoder 15 is connected to the bracket, and the rotating portion 151 of the rotary encoder 15 is connected to the rotating shaft 122 of the knob 12 and rotates synchronously with the knob 12. The structure is simple, so that the knob 12 can stably drive the rotating portion 151 of the rotary encoder 15 to rotate, so that the rotary encoder 15 can stably and reliably obtain the rotation angle information of the knob 12, so that the knob 12 and the rotary encoder 15 can cooperate to stably adjust the integrated audio 22.

[0063] In some embodiments of the present invention, reference Figure 3 As shown, the mounting plate 11 can be provided with an assembly groove 1102 for installing the knob 12, and the bottom of the assembly groove 1102 is provided with an assembly column 112 extending toward the groove, and the assembly column 112 is provided with a through hole 1103 along its own axis, and the fingerprint unlocker 13 is arranged at the end of the through hole 1103 away from the bottom of the assembly groove 1102, and the relative position of the fingerprint unlocker 13 and the assembly column 112 remains unchanged, and the knob 12 is sleeved on the side of the assembly column 112 through the avoidance hole 1201 and rotates with the assembly column 112, and the fingerprint unlocker 13 is connected to the assembly column 112, so that the fingerprint unlocker 13 no longer rotates with the knob 12, and the fingerprint unlocker 13 is stably and reliably mounted on the mounting plate 11 through the assembly column 112, avoiding excessive twisting of the cable, so that the fingerprint unlocker 13 and the knob 12 can operate more stably and reliably during the long-term use of the control component 10, thereby allowing the control component 10 to operate stably and reliably. The assembly column 112 has a simple structure, which makes it convenient and easy to assemble the knob 12, the fingerprint unlocker 13 and the mounting plate 11.

[0064] In some embodiments of the present invention, reference Figure 3 As shown, the rotary encoder 15 can be configured as a hollow encoder that is sleeved onto the side of the mounting post 112. This provides a simple structure, facilitates assembly, and makes the overall structure of the control assembly 10 more compact. In this embodiment, the knob 12 is sleeved onto the outside of the mounting post 112. After the knob 12 and the mounting post 112 are assembled, a portion of the mounting post 112 is inserted into the avoidance hole 1201, so that the rotating shaft 122 of the knob 12 is sleeved onto the mounting post 112.

[0065] In some embodiments of the present invention, reference Figure 3 As shown, the rotary encoder 15 is fastened to the bottom of the assembly slot 1102 , and the end of the assembly column 112 facing away from the bottom of the assembly slot 1102 is plug-connected to the fingerprint unlocker 13 .

[0066] In this embodiment, when the mounting plate 11 opens the assembly groove 1102, the rotary encoder 15 is tightly connected to the bottom of the assembly groove 1102, which has a simple structure, is convenient to fix, and is easy to disassemble, so that the rotary encoder 15 can be stably supported and fixed, so that the rotary encoder 15 can stably cooperate with the knob 12 for operation.

[0067] The assembly column 112 is plugged into the fingerprint unlocker 13, has a simple structure, and is easy to assemble. The assembly column 112 can provide good support for the fingerprint unlocker 13 in the axial direction of the knob 12, so that the fingerprint unlocker 13 can stably bear the pressure applied by the user through the assembly column 112 when in use, thereby making the fingerprint unlocker 13 operate stably and reliably.

[0068] In some embodiments of the present invention, Figure 4 As shown, the assembly column 112 and the fingerprint unlocker 13 are respectively provided with a locking protrusion 131 and a locking groove 1121 , and the fingerprint unlocker 13 and the assembly column 112 are engaged with each other through the locking protrusion 131 and the locking groove 1121 .

Optionally, the fingerprint unlocker 13 can also be provided with a connecting buckle, and the assembly column 112 can be provided with a corresponding latching hole. The fingerprint unlocker 13 and the assembly column 112 can be fixed together by the connecting buckle and the latching hole, so that the fingerprint unlocker 13 can be more securely connected to the assembly column 112.

[0070] In some embodiments of the present invention, reference Figure 3 As shown, when the mounting plate 11 is provided with an assembly groove 1102 , the knob 12 and the rotating portion 151 of the rotary encoder 15 can be plug-connected along the axial direction of the knob 12 .

[0071] In this embodiment, the knob 12 is plug-connected to the rotating portion 151 of the rotary encoder 15 , which has a simple structure and is easy to assemble. This allows for stable transmission of rotational force between the knob 12 and the rotating portion 151 of the rotary encoder 15 , and allows the rotary encoder 15 to stably obtain rotation angle information of the knob 12 .

[0072] In some examples of the present invention, Figure 6 and Figure 7 As shown, when the mounting plate 11 is provided with an assembly groove 1102, the inner wall of the avoidance hole 1201 can be provided with a plurality of plug-ins 1221 extending along the axial direction of the knob 12, and the plurality of plug-ins 1221 are arranged at intervals along the circumference of the knob 12.

When the mounting plate 11 is provided with an assembly hole 1101, the rotating shaft 122 is inserted into the inner ring of the bearing 14 and rotates synchronously with the inner ring of the bearing 14. When the mounting plate 11 is provided with an assembly groove 1102, the side wall of the assembly groove 1102 is provided with a plurality of limiting ribs 113 arranged circumferentially around the assembly groove 1102. The outer ring of the bearing 14 is embedded between the plurality of limiting ribs 113 of the assembly groove 1102. The side surface where the limiting rib 113 abuts against the outer ring of the bearing 14 is provided with a step surface for the bearing 14 to slide toward the bottom of the assembly groove 1102, and the outer ring of the bearing 14 abuts against the step surface.

[0075] In this embodiment, when the mounting plate 11 is provided with an assembly hole 1101, the inner ring of the bearing 14 is sleeved on the rotating shaft 122, and the outer ring of the bearing 14 is against the hole wall of the assembly hole 1101. The bearing 14 can play a good positioning and guiding role in the rotation of the knob 12, so that the knob 12 can rotate more stably and smoothly, thereby giving the user a better rotation experience when rotating the knob 12, and greatly improving the user's control experience.

[0076] In this embodiment, the knob 12 is mounted on the mounting plate 11 via a bearing 14, so that when an external force is applied to the knob 12, the force can be transmitted to the mounting plate 11 along the bearing 14, thereby reducing the transmission of the force on the rotary encoder 15, so that the rotary encoder 15 can be stably and reliably set on the mounting plate 11, so that the rotary encoder 15 and the knob 12 can operate more stably during the long-term use of the control assembly 10.

[0077] For example, when the knob 12 is subjected to an axial thrust, the thrust can be transmitted along the rotating shaft 122 of the knob 12 to the bearing 14 and then to the mounting plate 11, so that the force transmitted from the knob 12 to the rotary encoder 15 is smaller, so that the rotary encoder 15 can be stably mounted on the mounting plate 11.

[0078] In some embodiments of the present invention, reference Figure 3 and Figure 4 As shown, when mounting plate 11 is provided with a mounting groove 1102, mounting plate 11 is also provided with a plurality of retaining ribs 113 evenly arranged around the axis of bearing 14. Retaining ribs 113 are located on the walls of mounting groove 1102 and extend along the axis of mounting post 112. The sides of retaining ribs 113 facing bearing 14 abut against the outer ring of bearing 14. Furthermore, the sides of retaining ribs 113 facing bearing 14 are provided with a stepped structure to prevent bearing 14 from sliding toward the bottom of mounting groove 1102, with the stepped surface facing away from the bottom of mounting groove 1102. When bearing 14 is installed in mounting groove 1102, the axis of bearing 14 coincides with the axis of mounting post 112, and the outer ring of bearing 14 abuts against the stepped surface of retaining ribs 113.

[0079] In this embodiment, the step structure has a step surface facing the handle 121 of the knob 12. Specifically, in the axial direction of the bearing 14, the end face of the outer ring of the bearing 14 facing the bottom of the assembly groove 1102 abuts against the step surface, so that the outer ring of the bearing 14 can cooperate with the limiting rib 113 to transmit the force along the axial direction of the bearing 14. When the knob 12 is subjected to the external force along the axial direction of the knob 12, the limiting rib 113 can cooperate with the bearing 14 to stably and reliably support the knob 12, thereby effectively reducing the axial force transmitted to the rotary encoder 15 and other non-rotational external forces, so that the rotary encoder 15 and the knob 12 can operate stably in coordination.

[0080] In some embodiments of the present invention, Figure 6 As shown, the rotating shaft 122 of the knob 12 is circumferentially spaced apart with multiple engaging ribs 1222. The multiple engaging ribs 1222 extend axially along the knob 12. The sides of the engaging ribs 1222 facing away from the rotating shaft 122 are machined with stepped surfaces, with the stepped surfaces of the engaging ribs 1222 facing away from the handle 121 of the knob 12. When the bearing 14 is mounted on the side of the rotating shaft 122 of the knob 12, the stepped surfaces of the engaging ribs 1222 abut against the inner race of the bearing 14.

[0081] In some embodiments of the present invention, Figure 6 As shown, the side of the rotating shaft 122 of the knob 12 is also provided with a protruding elastic buckle 1223. When the bearing 14 is sleeved on the side of the rotating shaft 122 of the knob 12, the step surface of the rib 1222 and the elastic buckle 1223 are respectively located on both sides of the bearing 14, locking the position of the bearing 14.

[0082] In this embodiment, an elastic clip 1223 is further provided on the rotating shaft 122 of the knob 12 to engage with the inner ring of the bearing 14, so that the knob 12 can be more stably and reliably fixed to the inner ring of the bearing 14, thereby greatly reducing the probability of the knob 12 falling off during long-term use, so that the control component 10 can be used normally more stably and persistently.

[0083] In this embodiment, a snap-fit ​​rib 1222 is provided on the rotating shaft 122 to cooperate with and abut against the inner ring of the bearing 14, so that the fixing of the rotating shaft 122 and the inner ring of the bearing 14 is more secure and stable, so that the knob 12 can rotate more stably and smoothly during use, making the operation of the control assembly 10 more stable.

[0084] In some embodiments of the utility model, Figure 2 and Figure 3 As shown, the control assembly 10 may further include a decorative plate 16 , which is provided on an end surface of the handle 121 of the knob 12 away from the rotating shaft 122 , and has a connecting hole 161 , which is connected to the avoidance hole 1201 .

[0085] In this embodiment, a decorative plate 16 is provided on the end face of the knob 12, which has a simple structure and provides a better user experience. The decorative plate 16 is provided with a connecting hole 161 connected to the avoidance hole 1201, so that the fingerprint unlocker 13 in the avoidance hole 1201 can be exposed from the connecting hole 161, thereby meeting the user's usage needs.
