In order to make the technical solutions of the embodiments of the present invention better understood, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a thumb wheel structure, which specifically includes a base 10, a thumb piece 20, and a reset piece 30.
The base 10 and the toggle member 20 are rotatably connected through a rotating shaft 40, a first abutting portion 11 is arranged on the base 10, the toggle member 20 includes a second abutting portion 21 facing the rotating shaft 40, and the second abutting portion 21 and the first abutting portion 11 are adjacent in the radial direction of the rotating shaft 40.
The reset member 30 abuts against the first abutting portion 11 and the second abutting portion 21, when the toggle member 20 rotates on the base 10, the reset member 30 generates two abutting forces with opposite directions on the first abutting portion 11 and the second abutting portion 21, respectively, where the opposite directions are in the circumferential direction of the rotating shaft 40.
In an embodiment of the present invention, a possible adjacent relationship between the first abutting portion 11 and the second abutting portion 21 can refer to fig. 2, and fig. 2 is a top view of the thumb wheel structure shown in fig. 1, the first abutting portion 11 and the second abutting portion 21 can be adjacent, and a fit gap at the adjacent position can ensure that the first abutting portion 11 and the second abutting portion 21 do relative motion along the circumferential direction of the rotating shaft 40, so that the thumb wheel structure is more compact in structure, and is beneficial to reducing the overall volume.
In some embodiments, the second abutting portion 21 and the first abutting portion 11 may be spaced apart by a certain distance, so that the relative movement between the second abutting portion 21 and the first abutting portion 11 is smoother, and the phenomenon that the damping sense is too strong when the toggle 20 is operated is avoided.
The distance between the second abutting portion 21 and the first abutting portion 11 can be set according to actual needs, and in some possible embodiments, the distance between the second abutting portion 21 and the first abutting portion 11 can be set to be arbitrarily adjustable, for example, the second abutting portion 21 is movably connected to the toggle member 20 through an adjusting screw (or a part or component having a similar adjusting function) (not shown), and the distance between the second abutting portion 21 and the first abutting portion 11 is adjusted through screwing in or screwing out of the adjusting screw, so as to obtain different operation damping feelings, and adapt to the requirements of different users.
In some embodiments, referring to fig. 2, the first bunting portion 11 and the second bunting portion 21 may be both partial sector structures and have the same central angle; alternatively, the first abutting portion 11 and the second abutting portion 21 may be formed as a hollow structure, so that the overall weight of the thumb wheel structure can be reduced.
In the embodiment of the present invention, in a spatial relationship, the toggle member 20 may be located between the reset member 30 and the base 10 (as shown in fig. 1), and correspondingly, in this embodiment, the toggle member 20 is further provided with a through slot 22 disposed adjacent to the abutting portion, so that the first abutting portion 11 passes through the through slot 22 and is adjacent to the second abutting portion 21, and when the toggle member 20 rotates relative to the base 10, the through slot 22 defines a moving range of the first abutting portion 11; in an alternative embodiment, the through slot 22 is an arc-shaped slot, a center of the arc-shaped slot is located on a central axis of the rotating shaft 40, and a width of the arc-shaped slot (referred to as a dimension in a radial direction of the rotating shaft 40) is not less than a width of the first abutting portion 11 (referred to as a dimension in the radial direction of the rotating shaft 40).
In other embodiments, the reset element 30 may be located between the toggle element 20 and the base 10 in a spatial relationship (not shown), in which case the toggle element 20 may not be provided with the through slot 22 for engaging with the first abutting portion 11, and in this embodiment, the first abutting portion 11 and the second abutting portion 21 are engaged in a staggered manner during the assembly process of the toggle element 20 and the base 10.
In an embodiment of the present invention, the restoring element 30 may be a torsion spring, refer to fig. 2 again, and refer to fig. 3 and fig. 4 in combination, where fig. 3 is a partial sectional view of fig. 2, fig. 4 is a structural view of the torsion spring, the torsion spring includes a spring tube 31 and a first supporting leg 32 and a second supporting leg 33 extending from two ends of the spring tube 31, the spring tube 31 is sleeved on the rotating shaft 40, it can be seen from fig. 2 and fig. 3 that the first supporting leg 32 abuts against one side of the first abutting portion 11 and the second abutting portion 21, and the second supporting leg 33 abuts against the other side of the first abutting portion 11 and the second abutting portion 21; it should be noted that, in some embodiments, the first abutting portion 32 and the second abutting portion 33 may only contact with the first abutting portion 11 and the second abutting portion 21 in the initial state, and do not generate an abutting force, and the abutting force is generated when the base 10 and the toggle member 20 move relatively.
In some embodiments, the first supporting leg 32 and the second supporting leg 33 are arranged in a crossed manner, and a larger torque can be generated through a smaller torsion angle by adopting the crossed arrangement, so that the service life of the torsion spring can be prolonged under the condition of ensuring normal use; it should be noted that, in other possible embodiments, the first supporting leg 32 and the second supporting leg 33 may not be arranged in a crossed manner.
The advantage of using a torsion spring for the reset element 30 in this embodiment is that the toggle element 20 can be restored to the initial position by the same restoring force (or restoring torque, where the restoring torque refers to the torque for restoring the toggle element 20 from the rotated position to the initial position) when rotating in different directions and the operation feeling of the toggle element 20 in different directions can be kept consistent, as will be explained below with reference to fig. 5 and 6 (reference numerals of the components in the figures can refer to fig. 2).
Fig. 5 is a state diagram of the toggle 20 rotating clockwise by a certain distance or angle relative to the base 10 under an external force, and fig. 6 is a state diagram of the toggle 20 rotating counterclockwise by a certain distance or angle relative to the base 10 under an external force, where O is a rotation center, it is assumed that the distance or angle of rotation of the toggle 20 in fig. 5 and fig. 6 is the same, that is, the rotation angle of the first supporting leg 32 relative to the second supporting leg 33 in fig. 5 is the same as the rotation angle of the second supporting leg 33 relative to the first supporting leg 32 in fig. 6.
Wherein, when the toggle member 20 is in the state shown in fig. 5 (maintaining the action of the external force), the action force of the second abutting portion 21 on the first abutting portion 32 is F1, the force center is S1, the action force of the first abutting portion 11 on the second abutting portion 33 is F2, the force center is S2, at this time, the resultant moment generated by F1 and F2 is zero (i.e. the torsion spring keeps still), the abutting force of the first abutting portion 32 on the second abutting portion 21 (the magnitude is equal to F1) and the resultant moment generated by the external force are also zero (the toggle member 20 keeps still), when the external force is removed, the abutting force of the first abutting portion 32 on the second abutting portion 21 still exists, the moment formed by the restoring force of the toggle member 20 will move the toggle member 20 to the initial position, the deformation of the torsion spring is reduced during the movement, the magnitude of the abutting force of the first abutting portion 32 on the second abutting portion 21 will also gradually decrease, until the resultant moment of the abutting force of the first abutting leg 32 and the second abutting leg 33 acting on the second abutting portion 21 is zero, the toggle member 20 returns to the initial position and is in a static state.
When the toggle member 20 is in the state shown in fig. 6 (maintaining the action of the external force), the action force of the second abutting portion 21 on the second abutting portion 33 is F ' 1, the force-receiving center is S ' 1, the action force of the first abutting portion 11 on the first abutting portion 32 is F ' 2, the force-receiving center is S ' 2, the resultant moment generated by F ' 1 and F ' 2 is zero (i.e. the torsion spring remains still), the abutting force of the second abutting portion 33 on the second abutting portion 21 (the magnitude is equal to F ' 1) and the resultant moment generated by the external force are also zero (the toggle member 20 remains still), when the external force is removed, the abutting force of the second abutting portion 33 on the second abutting portion 21 still exists, the moment formed by the restoring force of the toggle member 20 will move the toggle member 20 to the initial position, the deformation of the torsion spring is reduced during the movement, the magnitude of the abutting force of the second abutting portion 33 on the second abutting portion 21 will also gradually decrease, until the resultant moment of the abutting force applied to the second abutting portion 21 by the second abutting portion 33 and the first abutting portion 32 is zero, the toggle member 20 returns to the initial position and is in a static state.
As can be understood from the above analysis in conjunction with fig. 5 and 6, since the rotation angle of the first supporting leg 32 relative to the second supporting leg 33 in fig. 5 is the same as the rotation angle of the second supporting leg 33 relative to the first supporting leg 32 in fig. 6, the elastic deformation amount of the torsion spring in fig. 5 and 6 is the same, and based on the symmetry of the thumb wheel structure, the distances from the force centers S1 and S '1 to the rotation center 0 will be the same, the distances from the force centers S2 and S' 2 to the rotation center 0 will be the same, according to the moment balance relationship, the magnitudes of F1 and F '1 will be the same, and the magnitudes of F2 and F' 2 will be the same, so that, when the external force is finally removed, the magnitude of the initial resisting force of the first supporting leg 32 on the dial 20 in fig. 5 will be the same as the magnitude of the initial resisting force of the second supporting leg 33 on the dial 20 in fig. 6, that is the same, that the dial 20 rotates in different directions or angles, the torsion springs can act on the second abutting portions 21 with the same abutting force, so that the stirring member 20 moves to the initial position after the external force is cancelled, the variation trends of the abutting force in the process of returning the stirring member 20 are consistent, and similarly, the variation trends of the acting force of the torsion springs on the stirring member 20 in different directions are consistent in the stirring process, so that the stirring member 20 has consistent stirring hand feeling in different directions.
In the embodiment of the present invention, as shown in fig. 7, the wheel structure further includes a packing member 50, and the packing member 50 is rotatably connected to the dial 20.
