It should be noted that the types of the magnet rotation detection sensor and the force sensor in the embodiment of the present invention may be selected according to actual application scenarios, and are not limited herein.

In some embodiments, the magnet rotation detection sensor is in contact with the second end of the rotating shaft, which means that when there is displacement of the rotating shaft, the displacement change of the magnet rotation detection sensor is driven by the displacement change of the second end of the rotating shaft. In some embodiments, when the rotating shaft has no displacement change, or is in an initial state, there is no interaction force between the magnet rotation detection sensor and the rotating shaft, and only touch.

In some embodiments, the fact that the FPC dome is in contact with the magnet rotation detection sensor means that when the rotating shaft is not displaced, there is no interaction force between the two, and only contact is performed.

In some embodiments, as shown in fig. 7, fig. 7 is a schematic structural diagram of another implementation manner of the knob assembly according to an embodiment of the present application, in which the rotating shaft 602 further includes a limiting member 707 and a rotating shaft body 708, the limiting member 707 is located at a second end of the rotating shaft and is assembled on the rotating shaft body 708, and a maximum radial width of the limiting member is greater than a radial aperture of the through hole;

the magnet 603 axially fitted to the second end of the rotation shaft 602 through the through hole includes:

after the magnet 603 is axially fitted to the shaft body 708 through the through hole, a stopper 707 is fitted to an end portion of the shaft body 708 on a side close to the magnet 603.

It should be noted that, by adding the limiting member, the axial movement of the magnet, particularly the movement in the direction away from the knob head, and even the magnet falls off from the rotating shaft can be prevented. Through the increase of locating part, can make magnet rotate detection sensor more accurate.

In some embodiments, the magnet may be assembled to the shaft by inserting one end of the shaft body through the through hole of the magnet, and then installing the stopper on a side of the shaft body away from the knob head. Because the maximum radial width of the limiting piece is greater than the radial aperture of the through hole, that is, as shown in fig. 7, the limiting piece after being assembled protrudes out of the magnet, so that the magnet can be prevented from moving towards the magnet rotation monitoring sensor.

In some embodiments, the position-limiting member comprises a screw, wherein the radial diameter of the head of the screw is larger than the aperture of the through hole of the magnet, the rotating shaft body comprises a screw hole matched with the screw, and the magnet is prevented from moving axially after the screw is rotated into the screw hole.

It should be noted that, in the embodiment of the present invention, the connection manner between the limiting member and the rotating shaft body may be a plurality of manners, such as welding, adhering, and the like.

It should be noted that, when the rotating shaft includes the limiting member, at this time, the magnet rotation detection sensor contacts with the limiting member, and will move along with the displacement direction of the rotating shaft. In some embodiments, the magnet rotation detection sensor and the limiting member may also be fixedly connected. In other embodiments, the magnet rotation detection sensor is only in contact with the limiting member and is not connected to the limiting member, at this time, when the rotating shaft moves towards the magnet rotation detection sensor, the magnet rotation detection sensor will be subjected to the pressure of the limiting member and also move along with the existence of the displacement, and when the rotating shaft moves away from the magnet rotation detection sensor and returns, the position of the magnet rotation detection sensor can be returned due to the elasticity of the FPCdome of the sensor.

In some embodiments, the knob head fits outside the housing of the terminal and the second end of the spindle fits inside the housing of the terminal. Therefore, a user can configure corresponding control instructions for each control action by controlling the knob head positioned outside the terminal shell, and then control the terminal. The rotation of the knob assembly can be detected by the magnet rotation detection sensor and/or the pressure of the knob assembly is detected by the force sensor and then converted into a corresponding electric signal, so that the terminal is controlled and adjusted, for example, the brightness and the volume of the terminal are adjusted by the rotation of the knob, and the page turning of the terminal is adjusted by the pressing of the knob.

In some embodiments, the connecting portion of the rotating shaft is further equipped with an annular sleeve, wherein the connecting portion includes a rotating shaft body contacting the housing of the terminal, the annular sleeve is sleeved on the connecting portion and contacts with at least a part of the inner surface of the annular sleeve when the rotating shaft rotates, and the outer surface of the annular sleeve is fixedly connected with the housing of the terminal. Through the setting of annular sleeve, can make the user when rotatory knob, there is the damping in the rotation process, and then obtain good rotation and feel.

The surface of the annular sleeve that contacts the housing of the terminal is the outer surface of the annular sleeve, and the surface of the annular sleeve that contacts the connecting portion of the rotating shaft is the inner surface of the annular sleeve.

In some embodiments, although there is a gap of 0.02-0.03mm between the annular sleeve and the connecting portion, there may be some slight radial play during the rotation of the rotating shaft, and at this time, there may be a contact surface between the annular sleeve and the connecting portion of the rotating shaft, and since the outer edge surface of the annular sleeve is fixedly connected to the housing of the terminal, the rotation of the rotating shaft will be damped by the friction of the annular sleeve.

In some embodiments, the outer surface of the annular sleeve may be fixedly coupled to the housing of the terminal by means including, but not limited to: welding, gluing, etc.

In some embodiments, a silicone ring is filled between the rotating shaft and the housing of the terminal. It should be noted that the silica gel ring is tightly filled between the rotating shaft and the shell at the terminal, and can seal the gap between the shell at the terminal and the rotating shaft, so as to achieve the waterproof and dustproof functions. The silica gel ring is sleeved on the rotating shaft, and the cross section of the silica gel ring can be circular, oval, square and the like, and is not limited herein. The thickness of the silicone ring can be set by a person skilled in the art according to needs, and is not limited herein. In some embodiments, if the rotating shaft includes a limiting member, the silicone ring is not sleeved on the limiting member. In some embodiments, it is understood that the silicone ring is fitted over the spindle body that contacts the inner wall of the housing of the terminal.

In some embodiments, at least one compression spring is further assembled between the silicone ring and the knob head, one end of the compression spring abuts against the knob head, and the other end of the compression spring abuts against the silicone ring. When the knob is driven to move towards the direction of the magnet through the knob head, the knob head compresses the compression spring, and the compression spring compresses the silica gel ring, so that the silica gel ring is always in an extrusion state no matter the knob head is rotated or pressed, and the waterproof and dustproof effects can be further achieved.

In some embodiments, after the rotating shaft body is rotatably arranged in the shell of the terminal, a cavity is formed between the rotating shaft and the shell of the terminal and is close to one side of the knob head, the depth of the cavity does not exceed the length of the rotating shaft body, and the cavity is used for accommodating the silicone ring. In other embodiments, the cavity is a variable cross-section cavity, and the cavity can be divided into a first cavity and a second cavity according to the direction from the knob head to the magnet, wherein the diameter of the first cavity is larger than that of the second cavity, when the knob head moves towards the magnet through the knob head, the knob head compresses the compression spring, and the compression spring compresses the silicon rubber ring to enable the silicon rubber ring to move from the first cavity to the second cavity. Because the rotating shaft body between the second cavity and the magnet is in contact with the shell of the terminal, the moving range of the silica gel ring is limited, and the pressing and the rotation of the knob head are limited.
