Description

Automobile switch gear structure

Technical Field

The invention relates to the field of automobile switches, in particular to an automobile switch gear structure.

Background

Generally, the gear structure of an automobile switch is complex, a gear track structure is arranged on a gear block, a pressure spring hole is arranged on a rotating block, a steel ball or a ball head support column is arranged on a pressure spring, so that the sliding block is arranged in the gear track to realize gear hand feeling, and the self-resetting of gears is realized by the shape of the gear track. The structure has high requirements on the precision and the smoothness of a gear track, the gear track surface and the top column ball head need to be polished during processing, the polishing process is difficult to control, and in addition, the mechanical sliding block structure is easy to wear after long-term high and low temperature use friction, so that the problems of gear shaking, blocking, clamping stagnation and the like are caused, the gear hand feeling of a switch is influenced, and the driving comfort is influenced.

Disclosure of Invention

The invention aims to provide an automobile switch gear structure, which solves the problems that the existing starting gear structure has high processing precision requirement, is easy to wear after long-term use and influences gear hand feeling.

The technical scheme adopted by the invention for solving the technical problems is as follows: a gear structure of an automobile switch comprises a shell, a socket fixedly arranged below the shell, a PCB arranged on the socket and a knob assembly which is arranged in the shell and can be shifted or rotated; a group of gear static magnets matched with the switch gears are arranged on the shell or the socket, and a gear moving magnet attracted with the gear static magnets is arranged on the knob assembly.

Preferably, the adjacent ends of the gear static magnet and the gear moving magnet have opposite magnetic poles.

Preferably, the gear static magnet and the gear moving magnet are permanent magnets.

As another scheme, the gear static magnet and the gear moving magnet are electromagnets.

Further, the knob assembly comprises a knob and a shifting block arranged below the knob, a gear moving magnet is arranged at the middle position of the bottom of the shifting block, and a gear static magnet is arranged under the gear moving magnet in the static state of the socket relative to the shifting block.

As the rotary knob, the rotary knob assembly comprises a rotary knob and a rotary block connected with the rotary knob, a gear moving magnet is arranged on the rotary block, and a group of gear static magnets matched with the gear moving magnet are arranged on the socket.

The invention has the beneficial effects that: the invention realizes the gear hand feeling of the switch by the principle that the magnets attract each other, and has the advantages of simple structure, convenient manufacture and installation and low cost. Meanwhile, the gear hand feeling is good, the application range is wide, and the gear hand feeling can be realized by adopting the structure no matter a rotary switch or a toggle switch. Meanwhile, the self-reset rotation and toggle switch can also assist in realizing the self-reset of the switch, reduce the torsion value of the self-reset spring and prolong the service life of the switch. Meanwhile, the permanent magnet is adopted, so that the structure is simple, and the arrangement and installation are convenient. The electromagnet is relatively complex in structure, but the magnetic force is convenient to adjust, so that the gear hand feeling of different switches can be met conveniently.

The invention will be explained in more detail below with reference to the drawings and examples.

Drawings

Fig. 2 is a sectional view of a switch structure of embodiment 2 of the present invention.

Detailed Description

Example 1: as shown in fig. 1, an automobile switch gear structure, in particular to a rotatable and toggle combined self-resetting switch structure, which comprises a housing 1, a socket 2 fixedly arranged below the housing 1, a PCB 3 arranged on the socket 2 and a knob assembly 4 arranged in the housing 1 and capable of toggling or rotating. The knob assembly 4 comprises a knob 41, an encoder assembly 43 arranged below the knob 41, and a shifting block 42 fixedly arranged below the encoder assembly 43, wherein the knob 41 rotates to drive the encoder assembly 43 to rotate, so that the function of rotating a switch and corresponding gear hand feeling are realized. A shifting magnet 6 is arranged at the middle position of the bottom of the shifting block 42, and a shifting static magnet 5 is arranged right below the shifting magnet 6 when the socket 2 is in a static state relative to the shifting block 42. The knob 41 is shifted to drive the encoder assembly 43 and the shifting block 42 to move, so that the gear moving magnet 6 is shifted relative to the gear static magnet 5, and after the knob 41 is loosened, the initial position is returned under the mutual attraction effect of the gear static magnet 5 and the gear moving magnet 6. The gear static magnet 5 and the gear moving magnet 6 are permanent magnets or electromagnets, and can be selected according to the actual arrangement space and cost of the switch, and the two magnets have advantages and disadvantages respectively. In order to ensure the attraction force, the adjacent magnetic poles of the gear static magnet 5 and the gear moving magnet 6 are opposite. Of course, the hand feeling of the gears can also be realized by adopting a matching structure of the magnet and the magnetic metal sheet, namely, the magnet is arranged on the shell or the knob assembly, and the metal sheet attracted with the magnet is correspondingly arranged on the knob assembly or the shell.

Example 2: the utility model provides an automobile switch keeps off position structure, concretely relates to rotary switch structure, as shown in fig. 2, including casing 1, the fixed socket 2 that sets up in casing 1 below, the PCB board 3 that sets up on socket 2 and install and to stir or pivoted knob assembly 4 in casing 1. The knob assembly 4 comprises a knob 41 and a rotating block 44 fixedly connected with the knob 41, a gear moving magnet 6 is arranged on the rotating block 44, and a group of gear static magnets 5 matched with the gear moving magnet 6 are arranged on the socket 2. The rotating block 44 is rotated to enable the gear moving magnets 6 on the rotating block 44 to be attracted with the gear static magnets 5 at different positions, so that gear hand feeling of different gears is realized. The rest is the same as example 1.

The invention is described above with reference to the accompanying drawings. It is to be understood that the specific implementations of the invention are not limited in this respect. Various insubstantial improvements are made by adopting the method conception and the technical scheme of the invention; the present invention is not limited to the above embodiments, and can be modified in various ways.
