Description
Technical field
The invention belongs to vehicle switch technical field, particularly relate to the anti-error switch of a kind of knob.
Background technology
Rotary switch is widely used in the electronic equipment of automobile, common rotary switch usually adopts knob certain angle in structural design, knob arrives specified gear according to the movement locus designed, the movable contact spring of switch internal and static contact are conducted, to realize corresponding fuction output.But, existing rotary switch generally lacks position-limit mechanism, makes the switch when operating easily occur rotating several grades or knob extremely rightabout situation continuously, and not easily make rotary switch accurate motion to the position of presetting.
If Chinese Patent Application No. is 200810304597.3 disclose a kind of rotary switch, it comprises base, be fixed on the collar on base, be limited to the rotary body between base and the described collar, be arranged at the first contact on rotary body, be arranged at the second contact on the collar, and the first adhesive part, the second adhesive part and the 3rd adhesive part.First adhesive part and the second adhesive part are arranged in the one of rotary body and the collar, and the 3rd adhesive part is arranged in the another one of rotary body and the collar.Although above-mentioned patent drives the first adhesive part or the second adhesive part and the 3rd adhesive part phase adhesive by rotary body, improve the anti-error performance of switch, the complex structure of switch, and installation time is longer.
Summary of the invention
Given this, the object of this invention is to provide the anti-error switch of a kind of knob, solve the problem of the easy misoperation of existing switch, and structure is simple, be easy to assembling.
The technical solution adopted for the present invention to solve the technical problems is: the anti-error switch of a kind of knob, comprises shell, to be axially disposed within shell and the rotating shaft upwards extended, to be arranged on the knob in rotating shaft, and to be arranged on the switch block between rotating shaft and shell.Wherein, knob is provided with the locking bolt that can move left and right, shell is provided with circular arc convex tendon, and on locking bolt, correspondence is provided with the first groove and the second groove that coordinate under different gear from circular arc convex tendon.When locking bolt is in left side shelves, circular arc convex tendon can rotate in the first groove; When locking bolt is in right side shelves, circular arc convex tendon can rotate in the second groove.Under initial condition, when locking bolt is in left side shelves, the circular arc convex tendon on shell can rotate in the first groove, and switch can turn right.Pressing locking bolt, when making it to be in right side shelves, circular arc convex tendon can rotate in the second groove, and switch can turn left.Adopting said structure, by setting up locking bolt on knob, making it the defect overcoming the easy misoperation of conventional knob switch, and the equal once injection moulding of knob, locking bolt and shell, structure is simple, is easy to assembling.
As a further improvement on the present invention, locking bolt is provided with two spherical holes, the steel ball being mounted with a stage clip between knob inwall and spherical hole and offseting with stage clip, and above-mentioned steel ball moves between two spherical holes.Said structure can not be moved when ensureing that locking bolt is in left side shelves or right side shelves, improves the reliability of switch, and stationarity when ensure that knob.
Further improve as of the present invention, between first groove and the second groove of locking bolt, be also provided with one for spacing positioning bar at the inwall of knob, the setting of this positioning bar limits the extreme position of the switching of circular arc convex tendon under different gear on shell.Be arranged with in the outside of rotating shaft and switch block the return spring helping rotating shaft return, and rotating shaft is also provided with the first voussoir, on the inwall of shell, correspondence is provided with the second voussoir coordinated with the first voussoir.By setting up the first voussoir and the second voussoir that cooperatively interact, under initial condition, both stop mutually, first press knob during operation and cross step on the second voussoir to a certain amount of first voussoir that makes, can rotate, namely the mode switched further by locking bolt motion and knob pressing combination overcomes the defect of the easy misoperation of conventional knob switch, and structure is simple, and reliability is high.
Beneficial effect of the present invention: the present invention by setting up locking bolt on knob, matched with the circular arc convex tendon on shell at corresponding gear respectively by the first groove on locking bolt, the second groove, realize the anti-error function of rotary switch, improve the reliability of switch, and structure is simple, and employee's efficiency of assembling improves greatly.Further, on the basis of original structure, matched by the first voussoir in rotating shaft and the second voussoir on outer casing inner wall, realize the locking of gear and the function of locking bolt motion and knob pressing combination switching, overcome the defect of the easy misoperation of conventional knob switch.
