DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0022] Furthermore, it is required that the present application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0023] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment provides an electronic device. Figures 1 to 3 The electronic device 100 provided in the embodiment of the present application includes: a housing 110, a rotating operating member 120, a Hall sensor 130 and a magnetic member 140. For example, when the electronic device 100 is a smart watch, the housing 110 is a watch case, and the rotating operating member 120 is a rotating crown of the smart watch.

[0025] The rotating operating member 120 is inserted through the housing 110, the Hall sensor 130 is disposed in the housing 110, the Hall sensor 130 is connected to the rotating operating member 120, and the magnetic member 140 is fixedly connected to the housing 110. The Hall sensor 130 is used to detect the magnetic field of the magnetic member 140. When the rotating operating member 120 is driven to rotate, the Hall sensor 130 rotates with the rotating operating member 120 and moves relative to the magnetic member 140.

[0026] In this way, in the embodiment of the present application, the magnetic member 140 is fixedly connected to the housing 110, so that the distance between the magnetic member 140 and the magnetic sensitive element can be increased by reasonably setting the position of the magnetic member 140, thereby reducing the influence of the magnetic member 140 on the magnetic sensitive element in the electronic device. In addition, since the Hall sensor 130 is connected to the rotating operating member 120, when the rotating operating member 120 is driven to rotate, the Hall sensor 130 rotates with the rotating operating member 120 and moves relative to the magnetic member 140, and then, the rotation of the rotating operating member 120 can be determined based on the change of the magnetic field detected by the Hall sensor 130.

[0027] It should be noted that the detection principle of the Hall sensor 130 can refer to the relevant technology, and the detection principle of the Hall sensor 130 will not be elaborated here.

[0028] It should also be noted that, illustratively, the rotation of the rotating operating member 120 can be determined by experiment based on the magnetic field obtained by the Hall sensor 130. For example, the parameters detected by the Hall sensor 130 when the rotating operating member 120 rotates to various angles can be recorded by experiment, and a mapping relationship can be established. Furthermore, in actual use, the rotation angle of the rotating operating member 120 can be determined based on the parameters detected by the Hall sensor 130.

[0029] In some embodiments, the electronic device 100 further includes a circuit board 150, and the Hall sensor 130 is electrically connected to the circuit board 150. For example, the circuit board 150 may be a mainboard of the electronic device 100. The Hall sensor 130 is electrically connected to the mainboard, so that the Hall sensor 130 can transmit a detection signal to the mainboard, so that the processing unit on the mainboard can determine the rotation of the rotating operating member 120 based on the detection signal. For example, the rotation direction or rotation angle of the rotating operating member 120 can be determined based on the detection signal. Thus, the electronic device 100 can be controlled based on the rotation direction or rotation angle of the rotating operating member 120.

[0030] In some embodiments, the circuit board 150 is fixedly connected in the housing 110, and the electronic device 100 further includes a connector 160, and the Hall sensor 130 is electrically connected to the circuit board 150 via the connector 160. Exemplarily, the connector 160 is a rotary electrical connector. The rotary electrical connector can realize the transmission of electrical signals between the rotating body and the fixed body. Among them, in an embodiment of the present application, the Hall sensor 130 is connected to the rotating operating member 120, so that the Hall sensor 130 can rotate around the rotating axis of the rotating operating member 120 as the rotating operating member 120 rotates. The circuit board 150 is fixedly connected in the housing 110. Therefore, the Hall sensor 130 is equivalent to the rotating member, and the circuit board 150 is equivalent to the fixed member. Furthermore, the Hall sensor 130 can be electrically connected to the circuit board 150 via the rotary electrical connector, so that the electrical signal of the Hall sensor 130 can be transmitted to the circuit board 150 via the rotary electrical connector.

[0031] In some embodiments, the connector 160 includes a substrate 161, a plurality of conductive rings 162, and a plurality of connectors 163. For example, the conductive rings 162 and the connectors 163 may be made of a copper-based alloy. The substrate 161 is fixedly connected to the rotating operating member 120. For example, the substrate 161 may be sleeved outside the rotating operating member 120 and fixedly connected to the rotating operating member 120. For another example, the substrate 161 may be directly bonded and fixed to the rotating operating member 120 by an adhesive.

[0032] refer to Figure 1 and Figure 2 Each conductive ring 162 is disposed on the base 161, and the center of each conductive ring 162 is located on the rotating shaft of the rotating operating member 120. The conductive rings 162 are sequentially sleeved in the order of diameter from small to large, in the direction away from the rotating operating member 120. It can be understood that the conductive ring 162 with the smallest diameter is located at the innermost side, the conductive ring 162 with the largest diameter is located at the outermost side, and the other conductive rings 162 are arranged between the conductive ring 162 with the smallest diameter and the conductive ring 162 with the largest diameter in the order of diameter from small to large.

[0033] It should be noted that the number of conductive rings 162 is equal to the number of pins of the Hall sensor 130. In other words, the number of conductive rings 162 is equal to the number of signal lines that the Hall sensor 130 needs to connect. For example, if the Hall sensor 130 needs to connect three signal lines, three conductive rings 162 are provided. Among them, the conductive ring 162 with the smallest diameter is located at the innermost side, the conductive ring 162 with the largest diameter is located at the outermost side, and the conductive ring 162 with a medium diameter is located in the middle.

[0034] Further, the connector 163 is fixed relative to the housing 110. Exemplarily, the electronic device 100 further includes a bracket 171. The bracket 171 is fixedly connected to the circuit board 150, and the circuit board 150 is fixedly connected to the housing 110, so that the connector 163 is fixed relative to the housing 110 via the bracket 171 and the circuit board 150. It should be noted that the connector 163 described here being fixed relative to the housing 110 means that the connector 163 will not move relative to the housing 110.

[0035] Furthermore, the connector 163 is in conductive contact with the conductive ring 162 in a one-to-one correspondence. The Hall sensor 130 is connected to the substrate 161, and the Hall sensor 130 is electrically connected to the conductive ring 162, and the connector 163 is electrically connected to the circuit board 150. In this way, the Hall sensor 130 can be electrically connected to the circuit board 150 via the conductive ring 162 and the connector 163, so that the signal of the Hall sensor 130 can be transmitted to the circuit board 150.

[0036] In some embodiments, the base 161 and the rotating operating member 120 may be fixedly connected in the following manner, so that the base 161 can rotate synchronously with the rotating operating member 120 , and thus the Hall sensor 130 disposed on the base 161 can also rotate synchronously.

[0037] Exemplarily, the base 161 is provided with a waist-shaped hole. The waist-shaped hole may also be referred to as a runway hole or a waist-shaped hole. Correspondingly, the end of the rotating operating member 120 facing the base 161 is provided with a boss adapted to the waist-shaped hole, so that the rotating operating member 120 can drive the base 161 to rotate synchronously by passing the boss through the waist-shaped hole. In other embodiments, the base 161 may also be provided with holes of other shapes besides the waist-shaped hole, as long as it can prevent the base 161 from slipping relative to the rotating operating member 120 during the rotation of the rotating operating member 120.

[0038] In some embodiments, a first annular groove 1621 is provided on one side of the conductive ring 162 facing the connector 163. The connector 163 is in conductive contact with the groove wall of the first annular groove 1621. In this way, the electrical connection effect between the connector 163 and the conductive ring 162 can be improved by the conductive contact between the connector 163 and the groove wall of the first annular groove 1621.

[0039] In some embodiments, a ball head 1631 is provided at one end of the joint 163 facing the first annular groove 1621, and the ball head 1631 is disposed in the first annular groove 1621. In this way, the electrical connection effect between the joint 163 and the conductive ring 162 can be further improved by providing the ball head 1631 at one end of the joint 163 facing the first annular groove 1621.

[0040] In some embodiments, the base 161 is provided with a plurality of second annular grooves 1611 adapted to the outer shape of the conductive ring 162, and each conductive ring 162 is embedded in the second annular groove 1611 in a one-to-one correspondence. In this way, by embedding the conductive ring 162 in the second annular groove 1611, the groove wall of the second annular groove 1611 can be used to provide support to the conductive ring 162, so as to prevent the conductive ring 162 from irreversible deformation due to long-term operation.

[0041] In some embodiments, a plurality of conductive portions 1612 are provided on a side of the substrate 161 away from the connector 163. The Hall sensor 130 is electrically connected to the conductive portion 1612. Exemplarily, the substrate 161 may include a circuit board substrate, and the conductive portion 1612 may be a first pad on the surface of the circuit board substrate. Furthermore, the soldering feet of the Hall sensor 130 may be soldered to the first pad, so that the Hall sensor 130 is electrically connected to the conductive portion 1612.

[0042] Furthermore, the conductive parts 1612 are electrically connected to the conductive rings 162 in a one-to-one correspondence. In this way, the Hall sensor 130 can be electrically connected to the circuit board 150 via the conductive parts 1612 , the conductive rings 162 and the connectors 163 .

[0043] It should be noted that, in some embodiments, when the base 161 includes a circuit board substrate, a second pad is further provided on the surface of the circuit board substrate. For example, the second pad and the first pad are respectively provided on opposite sides of the circuit board substrate. The second pad is electrically connected to the first pad in a one-to-one correspondence. The conductive ring 162 is soldered to the second pad in a one-to-one correspondence. Furthermore, an insulating material layer can be provided on the side of the circuit board substrate where the second pad is provided to wrap the outer surface of the conductive ring 162. In this way, the connection firmness between the conductive ring 162 and the base 161 can be improved by providing an insulating material layer on the outer surface of the conductive ring 162.

[0044] In some embodiments, the electronic device 100 further includes a bracket 171 . The bracket 171 is fixedly connected to the circuit board 150 , and the connector 163 is connected to the bracket 171 , so that the bracket 171 supports the connector 163 .

[0045] In some embodiments, the electronic device 100 further includes a stopper 172 and a spring 173. The rotating operating member 120 is provided with a snap-in slot 121. The snap-in slot 121 is used to snap-in the spring 173. The rotating operating member 120 passes through the housing 110, the stopper 172 and the base 161 in sequence. The spring 173 is snap-into the snap-in slot 121 of the rotating operating member 120 so that the base 161 is sandwiched between the stopper 172 and the spring 173.

[0046] In some embodiments, reference Figure 1 The Hall sensor 130 moves along the circular track with the rotating operating member 120, and the magnetic member 140 is located outside the circular track. In this way, the Hall sensor 130 can be rotated to a position opposite to the magnetic member 140 to increase the strength of the signal detected by the Hall sensor 130, thereby improving the detection accuracy of the Hall sensor 130.

[0047] Exemplarily, the magnetic component 140 is a block magnet, for example, the block magnet is specifically a rectangular parallelepiped magnet. Alternatively, the magnetic component 140 may also be a ring magnet. It is understandable that the cost of a block magnet is lower than that of a ring magnet, and thus, the use of a block magnet can reduce the material procurement cost. And since the volume of a block magnet is smaller than that of a ring magnet, the magnetic field strength of a block magnet is weaker than that of a ring magnet, and thus, the use of a block magnet can further reduce the interference of the magnetic component with the magnetically sensitive device.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
