Abstract

The utility model provides a heating switch for automobile seat, is including having reset spring's push rod, and this push rod is arranged the casing in and is removed the cooperation, and the button is connected in the push rod upper end, is equipped with the heart -shaped track groove of peach on the surface of push rod, and the one end of location hook is rotated and is connected in the casing, and another free end and the track groove guide mating that slides constitutes the self -lock device that presses the button. The utility model discloses utilize location hook and the heart -shaped track groove of peach to coordinate in inside, it is reliable from the locking bit, the operation comfortable feel to the reasonable compactness of overall structure, component assembly is convenient, makes the outward appearance small in size of whole switch simple.

Description

Automobile seat heating switching

Technical field: the utility model relates to the seat heating gauge tap of a kind of switching device, particularly automobile.

Background technology: many automotive seats have heat temperature raising function is to be generally equipped with seat heating switch to control. Because heat temperature raising need to keep a period of time, so seat heating switch requires there is self-lock of button device, after withdrawing, pressing operation power continues to keep switch conduction, until again press the disconnection of upspringing. Common self-lock of button apparatus structure more complicated, volume is compact not, produces assembling trouble, and the feel of pressing operation is stiff, and reliability also has much room for improvement.

Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of automobile seat heating switching of compactness rational in infrastructure.

The utility model comprises the push rod with back-moving spring, this push rod is placed in the mobile cooperation of housing, button is connected to push rod upper end, be provided with the rail groove of peach heart on the surface of push rod, one end of location hook is rotatably connected in housing, another free end and rail groove slippage guiding coordinate, and form self-lock of button device.

The utility model coordinates at the rail groove of inner utilization location hook and peach heart, and lock-bit is reliable, and operating handle is comfortable, and reasonable integral structure compactness, and Assembly of the parts is convenient, makes the outward appearance volume of whole switch small and exquisite simple.

Further illustrate the utility model below in conjunction with drawings and Examples.

Brief description of the drawings: Fig. 1 is the main structure schematic diagram of embodiment.

Fig. 2 is the schematic perspective view of push rod.

Fig. 3 is the enlarged diagram of Fig. 2 middle orbit groove location.

Fig. 4 is the A-A generalized section of Fig. 1.

Fig. 5 is the I portion enlarged diagram of Fig. 4.

Detailed description of the invention: as shown in Figures 1 to 4, be placed in the mobile cooperation of housing 1 with the push rod 2 of back-moving spring 4, button 3 is connected to push rod 2 upper ends, be provided with the rail groove 5 of peach heart on the surface of push rod 2, one end of location hook 6 is rotatably connected in housing 1, another free end and rail groove 5 slippage guiding coordinate, and form self-lock of button device. The present embodiment on the surface of push rod 2, rail groove 5 bottoms of peach heart are provided with guiding entrance 7, it is more reasonable to assemble like this, the free end of the location hook 6 injection groove 5 that more easily leads. In housing 1, be also furnished with indicator lamp 8, can luminous instruction after switch conduction, effect is more directly perceived.

When switch is during in original state, as shown in Figure 5, the free end of location hook 6 is positioned at guiding entrance 7 places, and not yet 5 slippages coordinate with rail groove.

In the time that button 3 is pressed downwards, push rod 2 moves down compression reseting spring 4, the functional circuit that conducting is simultaneously controlled, as shown in Figure 6, the now free end injection groove 5 of location hook 6, and be directed to the upper right corner of counterclockwise slippage to the heart-shaped rail groove 5 of peach.

Then when operating physical force is withdrawn, back-moving spring 4 resiliences make to move on push rod 2, as shown in Figure 7, the now free end of location hook 6 guiding slippage is to recess under the centre of the heart-shaped rail groove 5 of peach, can stablize and hook, propped up like this resilience of back-moving spring 4, it is motionless in self-locking state that push rod 2 keeps, and functional circuit continues conducting.

When again button 3 being pressed downwards, push rod 2 moves down, and as shown in Figure 8, the now free end of location hook 6 guiding slippage, to the upper left corner of the heart-shaped rail groove 5 of peach, can not continue to have hooked, and push rod 2 departs from self-locking state. Then operating physical force is withdrawn again, and back-moving spring 4 resiliences make to move and reset to original state on push rod 2, and the functional circuit of switch control disconnects.
