Description

Large-current microswitch

Technical Field

The utility model relates to a car seat electronic regulating switch especially relates to a heavy current micro-gap switch.

Background

At present, most automobiles are provided with electric seats, the electric adjusting switches of the seats are matched with an executing device for adjusting the seats to adjust the front and back positions of the seats, the gradient of a chair back, the height of the seats and the like, and therefore the body postures of users can be adjusted by adjusting the relative positions of the seats and an automobile body through the switches until the vehicles are in a more comfortable state. The reset force of the deflector rod of the conventional electric adjusting switch of the seat is provided by only the vertical spring or the elastic sheet, the vertical spring or the elastic sheet is subjected to fatigue fracture failure, the switch function is lost, and the common adjusting switch has high requirements on the model performance of the spring and the elastic sheet, adopts imported materials and has high cost.

Disclosure of Invention

The utility model provides a big current micro-gap switch that the switch resets rapidly, the durability is good.

In order to solve the above problem, the technical scheme of the utility model is that: the utility model provides a heavy current micro-gap switch, its constitution includes the upper cover body and the base of fixed mounting in upper cover body bottom, its characterized in that: the top of the upper cover body is provided with the rotation axis, fixed mounting has the driving lever of L type on the rotation axis, the one end of driving lever is passed the top of the upper cover body and is stretched into in the space that the upper cover body and base formed, the one end that the driving lever is located the upper cover body is provided with the recess, be provided with the push rod in the recess, the bottom of push rod is spherical, both ends are provided with contact one and contact two respectively about the base, the bottom of base still is provided with three stitch, still be provided with the pillar on the base, be provided with wavy shell fragment on the pillar, three stitch run through the base respectively and respectively with contact one, pillar and two fixed connection of contact, the bottom of push rod and the centre position in close contact with of shell fragment.

In order to ensure that the resetting effect is better and improve the hand feeling in the operation process, the top end of the push rod is provided with a spring.

The utility model has the advantages that: this novel car seat electronic regulating switch resets rapidly than traditional electronic switch, and the break-make is clear, and intensity is high, saves space, and durability can be strong, has extensive marketing space. And through setting up the driving lever of L type, it is more convenient to operate, does benefit to the regulation.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the device comprises a rotating shaft 1, a push rod 2, a spring 3, an upper cover 4, an elastic sheet 5, a first contact 6, a base 7, a pin 8, a deflector rod 9, a second contact 10 and a support 11.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

In fig. 1, a high-current microswitch comprises an upper cover 4 and a base 7 fixedly mounted at the bottom of the upper cover 4, and is characterized in that: the top of the upper cover body 4 is provided with rotation axis 1, fixed mounting has the driving lever 9 of L type on the rotation axis 1, the one end of driving lever 9 is passed the top of the upper cover body 4 and is stretched into in the space that the upper cover body 4 and base 7 formed, the one end that driving lever 9 is located the upper cover body 4 is provided with the recess, be provided with push rod 2 in the recess, the bottom of push rod 2 is spherical, both ends are provided with contact one 6 and contact two 10 respectively about base 7, the bottom of base 7 still is provided with three stitch 8, still be provided with pillar 11 on the base 7, be provided with corrugated shell fragment 5 on the pillar 11, three stitch run through base 7 respectively and respectively with contact one 6, pillar 11 and contact two 10 fixed connection, the centre position in close contact of the bottom of push rod 2 and shell fragment 5.

The top end of the push rod 2 is provided with a spring 3.

Because the middle position of the elastic sheet 5 is V-shaped, the bottom of the push rod 2 is at the middle position of the V-shaped structure of the elastic sheet 5, when the push rod works, the shift rod 9 is pressed downwards, one end of the shift rod 9 in the upper cover body 4 starts to move leftwards, the push rod 2 is further driven to move leftwards, the left end of the elastic sheet 5 is further driven to incline downwards, the right end of the elastic sheet 5 tilts upwards until the right end of the elastic sheet is disconnected with the second contact 10, and the left end of the elastic sheet is in contact conduction with the; after the conduction, the middle position of the elastic sheet 5 is V-shaped, and the push rod can automatically move to the lowest position of the V-shaped structure, so that the reset is completed.
