Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments more apparent, the present invention is further described in detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The embodiment is basically as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, a microswitch for a seat belt comprises a housing, a first elastic sheet 3 and a second elastic sheet 4, wherein the housing comprises a fixed cover 2 and a fixed cover 2, a fixed seat 1 and the fixed cover 2 are detachably fixed together, an accommodating space is arranged in the housing, the first elastic sheet 3 and the second elastic sheet 4 are separately and fixedly installed in the accommodating space, a first end of the first elastic sheet 3 is in contact with a first end of the second elastic sheet 4, a second end of the first elastic sheet 3 and a second end of the second elastic sheet 4 are respectively connected with a circuit connector 8 on a closed loop, a sliding groove 15 is arranged on the fixed seat 1, a sliding block 16 is arranged in the sliding groove 15, a rotating block is installed outside the accommodating space, and comprises a rotating shaft 5, a first rotating sheet 6 and a second rotating sheet 7, the rotating shaft 5 is installed on the fixed seat 1, the first rotating piece 6 and the second rotating piece 7 are installed on the rotating shaft 5, the first rotating piece 6 extends into the accommodating space, the tip of the first rotating piece 6 is in contact with the first end of the first elastic piece 3, and the second rotating piece 7 extends outwards into the sliding groove 15.
The first elastic sheet 3 and the second elastic sheet 4 are separately fixed in the accommodating space, and except that the first end of the first elastic sheet 3 is in contact with the first end of the second elastic sheet 4, other contact positions are not available. When the first elastic sheet 3 is contacted with the second elastic sheet 4, the alarm circuit is switched on. When the first circuit is out of contact with the second circuit, the alarm circuit is open. The rotating shaft 5 is arranged outside the left side of the accommodating space, the first rotating sheet 6 and the second rotating sheet 7 are arranged on the rotating shaft 5, and the first rotating sheet 6 is driven to rotate when the second rotating sheet 7 rotates. The second rotating piece 7 extends into the sliding groove 15, and when the sliding block 16 in the sliding groove 15 slides (the sliding block 16 is driven by the safety belt to move, and the connection mode and the movement process between the sliding block 16 and the safety belt are prior art and are not described in detail here), the second rotating piece 7 is extruded to drive the second rotating piece 7 to rotate. The tip of the first rotating piece 6 is in contact with the tip of the first elastic piece 3, and the first elastic piece 3 can be tilted when the first rotating piece 6 rotates.
The fixing seat 1 is provided with a pin hole 17, the fixing cover 2 is provided with a bolt 18, and the pin hole 17 is matched with the bolt 18. Two pin holes 17 are arranged on the fixed seat 1, and two bolts 18 are arranged on the fixed cover 2. The bolt 18 is inserted into the pin hole 17 to detachably fix the fixing cover 2 and the fixing seat 1 together, so that the installation and the later-period replacement are convenient.
A first fixing groove 9 and a second fixing groove 10 are formed in the accommodating space, the first elastic sheet 3 is fixedly installed in the first fixing groove 9, and the second elastic sheet 4 is fixedly installed in the second fixing groove 10. The first fixing groove 9 is used for fixing the longitudinal position of the first elastic sheet 3, and the second fixing groove 10 is used for fixing the longitudinal position of the second elastic sheet 4.
A first fixing block 11 is arranged in the first fixing groove 9, a first fixing port 12 is arranged on the first elastic sheet 3, the first fixing block 11 is matched with the first fixing port 12, a second fixing block 13 is arranged in the second fixing groove 10, a second fixing port 14 is arranged on the second elastic sheet 4, and the second fixing block 13 is matched with the second fixing port 14. The first fixing opening 12 and the first fixing block 11 fix the first elastic sheet 3 so that the first elastic sheet does not move transversely. The second fixing opening 14 and the second fixing block 13 fix the second elastic sheet 4 so that the second elastic sheet does not laterally displace.
A bump 19 is arranged at the first end of the second elastic sheet 4. The protrusion 19 is added to prevent the second elastic sheet 4 from being damaged due to the first elastic sheet 3 rebounding many times after a long time use.
An open slot 20 is arranged in the center of the first end of the first elastic sheet 3. The open slot 20 can increase the accessibility of the first elastic sheet 3 and the first rotating sheet 6.
The following is further detailed by the specific embodiments: when the belt is not inserted, the slider 16 is in the initial position. The first elastic sheet is contacted with the second elastic sheet 4, and the circuit is conducted. The alarm device is in a working state and reminds people to insert the safety belt.
When the belt is inserted, the slider 16 slides under the belt. The slider 16 then comes into contact with the second rotating piece 7 and presses the second rotating piece 7 to rotate it. When the second rotating piece 7 rotates, the second rotating piece 7 drives the first rotating piece 6 to rotate. When rotating, the first rotating piece 6 prizes the first elastic piece 3, so that the first elastic piece 3 deforms. Finally, the first elastic sheet 3 is separated from the second elastic sheet 4, the circuit is disconnected, and the alarm device does not work any more.
When the safety belt is taken out, the sliding block 16 returns to the initial position, and the first elastic sheet 3 is contacted with the second elastic sheet 4 again. The circuit is switched on and the alarm device works.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
