For example, one control base 2 corresponds to volume control of the car audio, and the other control base 2 corresponds to temperature control of the car air conditioner, and the like. So set up, because operating knob 1 all forms the detachable connection with each control base 2, consequently, same operating knob 1 is dismantled the back on current control base 2, can also continue to install on another control base 2, carries out another kind of functional parameter adjustment, realizes "one button multi-purpose" function.

In order to facilitate the detachable installation of the operation knob 1 on the control base 2, in this embodiment, a detachable opening 25 is designed at one end of the base 21, and the operation knob 1 is connected with the base 21 in a pluggable manner through the detachable opening 25. Specifically, the end face of one end of the base 21 is a plane, and the base 21 has an open structure, at this time, the dismounting opening 25 is an opening of the base 21, and the operation knob 1 can be inserted into or pulled out from the opening of the base 21.

When the operation knob 1 is inserted from the detachable opening 25, the operation knob 1 is pressed against the top surface of the lifting portion 22.

As shown in fig. 5, fig. 5 is a perspective view of the upper half of the structure of the inside of the control base 2.

In an alternative embodiment of the lifting portion 22, the lifting portion 22 is a split structure, and specifically includes a mounting cover 221 and a sliding sleeve 222. The mounting cover 221 is a main body member of the lifting portion 22, and its top surface is mainly used for supporting the operation knob 1, and its bottom surface is mainly used for parts such as the sliding sleeve 222 and the first magnet 23. The slide bush 222 is provided on the bottom surface of the mounting cover 221, is sleeve-shaped as a whole, is a core moving member of the entire control base 2, and can slide in the axial direction in the seat body 21. Accordingly, in order to ensure that the sliding sleeve 222 can stably perform the axial sliding lifting motion, the guiding ring table 26 is vertically arranged on the bottom surface of the seat body 21 in this embodiment. The guide ring table 26 is generally annular, and is mainly configured to form an axial sliding fit with the sliding sleeve 222, so as to form a motion supporting and guiding function for the sliding sleeve 222, so that the sliding sleeve 222 can axially lift and slide along the guide ring table 26.

Specifically, in this embodiment, the outer wall surface of the sliding sleeve 222 is convexly provided with the guide rib 223, and meanwhile, the inner wall surface of the guide ring table 26 is provided with the guide groove 261, and the guide groove 261 and the guide rib 223 can form a sliding fit, and both extend for a certain length along the axial direction. The guide rib 223 on the sliding sleeve 222 is inserted into the guide groove 261 on the guide ring table 26, so that the sliding sleeve 222 and the guide ring table 26 form an axial sliding fit, and the lifting movement of the sliding sleeve 222 is guided by the fit of the guide rib 223 and the guide groove 261.

The axial distance is the maximum descending distance of the lifting part 22, that is, the maximum sedimentation height of the operation knob 1, and in the design stage, it is only necessary to ensure that the axial distance is smaller than a certain value of the thickness (or height) of the operation knob 1.

In an alternative embodiment regarding the mounting cover 221, considering that the conventional knob switch must generally be opened by matching with the knob on the mounting panel, resulting in poor tightness of the entire knob switch and easy dust accumulation and water inflow, in order to achieve the entire sealing of the knob switch, in this embodiment, when one end of the base 21 is provided with the convex ring 211, the top surface of the mounting cover 221 will abut against the bottom surface of the convex ring 211 and cover the dismounting opening 25 in a natural state, so as to achieve the sealing of the base 21 by the mounting cover 221. Generally, the mounting cover 221 may be circular or polygonal, for example, the mounting cover 221 and the mounting opening 25 are concentrically distributed, and the diameter of the mounting cover 221 is larger than the diameter of the mounting opening 25. So arranged, in a natural state, the top surface of the mounting cover plate 221 is abutted against the bottom surface of the convex ring 211 and covers the dismounting opening 25, so that the sealing effect of the seat body 21 is realized, and foreign matters such as external dust or liquid are effectively prevented from entering the interior of the seat body 21 through the dismounting opening 25; further, after the operation knob 1 is detached and removed from the control base 2, the mounting cover 221 is reset by the automatic lifting of the lifting portion 22 to reseat the mounting/dismounting port 25, thereby automatically sealing the seat 21.

In addition, when the end face of one end of the base 21 is a plane, in order to achieve the sealing effect of the base 21, the outer edge face of the mounting cover 221 may be abutted against the inner wall face of the base 21, so as to cover the opening of the base 21, and of course, the shape of the mounting cover 221 is the same as the cross-sectional shape of the base 21 at this time, so as to achieve tight abutment; further, sliding friction is formed between the outer edge surface of the mounting cover 221 and the inner wall surface of the housing 21, so as to avoid obstructing the degree of freedom of the lifting movement of the lifting portion 22.

In an alternative embodiment with respect to the sliding sleeve 222, the sliding sleeve 222 is not directly connected to the mounting plate 221, but is connected via a connecting sleeve 225. Specifically, the connecting sleeve 225 is disposed on the bottom surface of the mounting cover 221, specifically is in a ring-sleeved structure, and extends downward for a certain distance along the axial direction, and the top end of the sliding sleeve 222 is inserted into the connecting sleeve 225 to realize fixed connection. The inner wall of the connecting sleeve 225 is provided with a clamping groove 226, correspondingly, the outer wall of the sliding sleeve 222 is convexly provided with a clamping block 224, and the clamping groove 226 and the clamping block 224 can form clamping fit, so that the sliding sleeve 222 is clamped in the connecting sleeve 225, and the dismounting operation can be conveniently carried out.

In order to facilitate the mounting of the first magnet 23 on the lifting portion 22, in the present embodiment, the first magnet 23 is mounted on the bottom surface of the mounting cover 221. Specifically, a mounting groove is opened on the bottom surface of the mounting cover 221 to mount the first magnet 23 into the mounting groove. Meanwhile, in order to facilitate adjustment of magnetic repulsion between the first magnet 23 and the second magnet 24, a detachable connection is specifically formed between the first magnet 23 and the mounting cover 221, for example, the first magnet 23 and the mounting groove are connected in a clamping manner, so that the first magnet 23 and the mounting groove are conveniently detached, and therefore magnetic force parameters of the first magnet 23 are adjusted, and magnetic repulsion between the first magnet 23 and the second magnet 24 is adjusted. Of course, the mounting may also be by fasteners or adhesives.

As shown in fig. 6, fig. 6 is a perspective view of the lower half of the structure of the inside of the control base 2.

In order to facilitate the installation of the second magnet 24 in the housing 21, in this embodiment, an installation cylinder 27 is also erected on the bottom surface of the housing 21, and the installation cylinder 27 is mainly used for installing the second magnet 24. Specifically, the mounting cylinder 27 is generally located in the central area of the bottom surface of the base 21, and the second magnet 24 and the mounting cylinder 27 form a sliding fit, so that the second magnet 24 can slide along the mounting cylinder 27 to slide down from the nozzle of the mounting cylinder 27 to the bottom of the mounting cylinder for mounting, or slide up the second magnet 24 along the mounting cylinder 27 to slide out from the nozzle of the mounting cylinder for dismounting, so as to conveniently adjust the magnetic force parameter of the second magnet 24, and further adjust the magnetic repulsive force between the first magnet 23 and the second magnet 24.

Further, not only the first magnet 23 and the second magnet 24 may be installed in the control base 2, but also a magnetic material may be provided in the operation knob 1. Specifically, the magnetic material piece can be influenced by the magnetic attraction force of the first magnet 23 and the second magnet 24, such as magnetic metals of iron, cobalt, nickel, etc., so that after the operation knob 1 is mounted in the control base 2, on one hand, the operation knob 1 will be attracted to the top surface of the mounting cover 221 under the magnetic attraction force of the first magnet 23; on the other hand, a pressing force is applied to the lifting portion 22 by the magnetic attraction force of the second magnet 24, and the auxiliary lifting portion 22 is lowered against the magnetic repulsive force between the second magnet 24 and the first magnet 23.

Similarly, the magnetic material piece is detachably mounted in the operation knob 1 so as to conveniently adjust the magnetic parameters and acting forces of the magnetic material piece and the first magnet 23 and the second magnet 24.

In another embodiment of the present utility model, in order to achieve the automatic lifting and resetting movement of the lifting and lowering portion 22 when the operation knob 1 is disengaged from the control base 2, the magnetic repulsive force between the second magnet 24 and the first magnet 23 of the foregoing embodiment can be achieved, and the elastic member 3 can also be achieved.

Meanwhile, in a natural state, the bottom surface of the mounting cover plate 221 presses the top end of the elastic piece 3, the elastic piece 3 has a certain elastic compression amount, and a certain elastic pre-tightening force is formed on the mounting cover plate 221. So arranged, when the operation knob 1 is placed on the top surface of the lifting part 22, the elastic piece 3 is continuously compressed, and the elastic pretightening force is increased; when the operation knob 1 is taken out from the control base 2, the lifting part 22 can be driven independently by the elastic force of the elastic member 3 to quickly lift and reset without using magnetic repulsive force. Of course, both the elastic force of the elastic member 3 and the magnetic repulsive force between the second magnet 24 and the first magnet 23 may also work together to drive the lifting portion 22 to perform the lifting and resetting movement at the same time. In addition, the top surface of the mounting cover 221 can be more closely abutted against the top surface of the collar 211 by utilizing the elasticity of the elastic member 3, thereby improving the sealing performance.

In general, the elastic members 3 may specifically be springs, elastic columns, etc., and may be simultaneously disposed in the seat 21, and each elastic member 3 may be uniformly distributed along the circumferential direction of the seat 21, so as to ensure that the bottom surface of the mounting cover 221 is uniformly stressed around the circumferential direction.

Furthermore, the elastic member 3 is detachably connected with the mounting cover 221 and the bottom surface of the base 21, for example, by fastening members, so as to conveniently detach and replace the elastic member 3, and further conveniently adjust the elastic parameters of the elastic member 3.

In addition, in an alternative embodiment with respect to the base 21, the base 21 may be of unitary construction or of split construction. When the base 21 is in a split structure, a bottom cover 28 is further provided at the bottom of the base 21, and the bottom cover 28 is specifically connected with the base 21 by a fastener such as a bolt, so as to form a closed structure with the base 21, and meanwhile, the guide ring table 26, the mounting cylinder 27, the elastic member 3 and other parts can be conveniently mounted by using the bottom cover 28.
