Description
Technical field
What the present invention relates to is a kind of ignition switch device, in particular a kind of minicar ignition switch device.
Background technology
Present miniature agricultural vehicle ignition switch device operation principle is: through the key on the rotation igniting lock core; Can turn to OFF (locking), ACC (electrical appliance), ON (going), preheating (H), ST (starting) gear; In the igniting assembly, form different gear circuit output, realize corresponding function.But because this type of switch is limited by space outerpace, ignition switch realization circuit position is often rotated on rear cover assembly by a contact bridge, realizes function; When switch is in the ST shelves; Needing four contact points on the rear cover assembly contacts simultaneously on contact bridge; Owing to just confirmed a plane at 3, certainly will cause one of them contact point can produce loose contact, this ignition switch in the market can't solve owing to this problem; Often cause contact performance bad, the disposable in process of production qualification rate of product is also extremely low simultaneously.Simultaneously since the agricultural vehicle driving cabin owing to be not airtight; Ignition switch is stained with dust or other foreign material easily; Even possibly get into ignition switch inside at the rainy day rainwater, cause the ignition switch metalwork to produce corrosion, nonmetal parts accelerated ageing; Reduce and to cause that also switch produces short circuit when normal running, cause switch failure useful life.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; A kind of minicar ignition switch device is provided; Through improvement, guarantee that four contacts on the rear cover assembly can in one plane simultaneously overcome the defective of present product when the ST shelves to the contact axle assembly.
The present invention realizes through following technical scheme, the present invention includes rear cover assembly and contact bridge assembly, and said contact bridge assembly comprises contact bridge body, contact bridge working face, flexure strip and adjustment contact; On the front that is arranged on the contact bridge body of contact bridge working face convexity; Flexure strip is positioned at the back side of contact bridge body; One end of flexure strip is fixed on the contact bridge body; The other end is fixedly linked with the adjustment contact, and the adjustment contact is positioned on the contact bridge working face, and on the contact bridge working face and corresponding position, adjustment contact is provided with and is used to adjust the through hole that the contact is passed; Rear cover assembly and contact bridge assembly are used, and the mid portion of contact bridge assembly is provided with rotatable interface, and rear cover assembly is provided with five contact contacts.
The height of said adjustment contact is higher than the height of contact bridge working face, makes things convenient for the contact on the rear cover assembly to touch.
On the contact bridge body, technology is simple through rivet for said flexure strip.
Said flexure strip is that the beryllium-bronze of 0.2～0.4mm is processed by thickness; Thin beryllium-bronze has certain elasticity, and when the adjustment contact was pressed onto by the contact contact on the rear cover assembly, flexure strip can be crooked; When not stressing on the adjustment contact, flexure strip can restore to the original state.
Said contact bridge working face is provided with the dead slot that groove depth is 0.3～0.5mm, and through hole is positioned at dead slot.After use through certain hour the contact contact on the rear cover assembly, wearing and tearing in various degree can take place, this dead slot is set can guarantees when the ST shelves, four contact contacts can can't be not in one plane because of wearing and tearing.
Five contact contact heights on the said rear cover assembly are identical, and different gears are realized through the contact of contact bridge working face in different contact contacts.
The present invention also comprises key, lock core and moving block, and said key is arranged in the lock core, and lock core is connected with moving block, and moving block is connected with the contact bridge assembly through rotatable interface.
Said lock core is provided with protective cover, and after key was extracted, protective cover can cover lock core, played the effect of sealing.
Said moving block, contact bridge assembly and rear cover assembly outsourcing are covered with the rubber guard shield, prevent that external dust and foreign matter from sticking to switch external, can well protect the insulating properties of each contact point, avoid the switch short circuit.
The present invention compares prior art and has the following advantages: ignition switch of the present invention has improved the disposable qualification rate of production, has solved the high present situation of failure rate after sale, realizes dustproof and waterproof simultaneously, improves life of product.

Embodiment
Elaborate in the face of embodiments of the invention down, present embodiment provided detailed execution mode and concrete operating process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, present embodiment key 1, lock core 2, moving block 3, contact bridge assembly 4 and rear cover assembly 5, contact bridge assembly 4 comprise contact bridge body 41, contact bridge working face 43, flexure strip 44 and adjustment contact 42; On the front that is arranged on contact bridge body 41 of contact bridge working face 43 convexities; Flexure strip 44 is positioned at the back side of contact bridge body 41; One end of flexure strip 44 is fixed on the contact bridge body 41; The other end is fixedly linked with adjustment contact 42, and adjustment contact 42 is positioned on the contact bridge working face 43, and on the contact bridge working face 43 and 42 corresponding positions, adjustment contact are provided with and are used to adjust the through hole that contact 42 is passed; Rear cover assembly 5 is used with contact bridge assembly 4, and the mid portion of contact bridge assembly 4 is provided with rotatable interface 46, and rear cover assembly 5 is provided with five contact contacts.
The height of adjustment contact 42 is higher than the height of contact bridge working face 43 in the present embodiment, makes things convenient for the contact on the rear cover assembly 5 to touch.
