Description
Technical Field
The invention relates to the technical field of sensors, in particular to a sensor for reminding wearing of a safety belt and an automobile safety seat thereof.
Background
As shown in fig. 1, a conventional seat belt reminder wear sensor 10 is shown in block diagram form. As shown in fig. 2, which is an exploded view of the conventional seat belt reminder wear sensor 10 shown in fig. 1.
The conventional seatbelt reminder wear sensor 10 includes: a base 11, an elastic sheet 12 which is arranged on the base 11 and can elastically deform, and a micro switch 13 which is arranged on the base 11. Wherein, both ends of the elastic sheet 12 form a fixed end 12a and a movable end 12b, respectively, and an arched and curved deformation portion 12c is formed between the fixed end 12a and the movable end 12 b.
The deformation part 12c of the elastic sheet 12 is forced, the deformation part 12c is stressed to deform, and the movable end 12b is displaced to trigger the trigger head on the micro switch 13 due to the fixation of the fixed end 12a, so that the micro switch 13 sends out an induction signal.
The deformation part 12c of the elastic sheet 12 is released from being applied with force, the deformation part 12c returns to elastic deformation, the movable end 12b is reversely displaced to be separated from the trigger head on the touch micro switch 13, and the micro switch 13 does not generate an induction signal outwards.
This traditional safety belt reminds wearing sensor 10 to set up in car seat's sponge cushion below, thereby when personnel sits on the sponge cushion, thereby the sponge cushion can take place to sink to realize the deformation portion 12c application of force to elastic sheet 12, and then makes deformation portion 12c atress take place deformation, and when personnel left the sponge cushion, the sponge cushion no longer applied force to the deformation portion 12c of elastic sheet 12, and then deformation portion 12c resumes elastic deformation.
After the conventional seat belt reminding wearing sensor 10 is put on the market, in a long-term use process, the following technical problems are fed back by a user:
(1) The elastic sheet 12 is easy to excessively deform and can not well recover elastic deformation in the long-term use process, particularly when the elastic sheet 12 is subjected to huge impact force, so that the sensitivity of the whole sensor is reduced;
(2) The clearance between the movable end 12b of the elastic piece 12 and the side wall of the base 11 is too small (as shown in fig. 3), so that the smoothness of the movement of the movable end 12b is reduced: for example, during the reciprocating displacement of the movable end 12b, the shake of the movable end 12b inevitably rubs against the side wall of the base 11 to cause jamming; as another example, under a high temperature environment, the movable end 12b and the side wall of the base 11 expand, which causes the movable end 12b to directly contact with the side wall of the base 11 to cause a locking phenomenon; for another example, during long-term use, the movable end 12b and the side wall of the base 11 are aged to cause sol, which causes adhesion between the movable end 12b and the side wall of the base 11;
(3) Because this traditional safety belt reminds wearing sensor 10 is set up in car seat's sponge cushion below, and sponge cushion and the deformation portion 12c of elastic sheet 12 contact or separation, in long-term use, the position that sponge cushion and deformation portion 12c correspond can take place to sunken, and this sunken appearance can make there is the application of force blank between the deformation portion 12c of sponge cushion and elastic sheet 12 to the sensitivity of sensor has been reduced.
Therefore, how to further optimize the structure of the conventional seat belt reminder wearing sensor 10 to solve the technical problem fed back by the user is a technical problem that the designer needs to solve.

The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 4 and 5, the present invention discloses a seat belt reminder wearing sensor 20, comprising: the device comprises a base 100, an elastic sheet 200 which is arranged on the base 100 and can elastically deform, and a micro switch 300 which is arranged on the base 100.
As shown in fig. 7, both ends of the elastic sheet 200 are respectively formed with a fixed end 210 and a movable end 220, and an arched and curved deformation portion 230 is formed between the fixed end 210 and the movable end 220.
The fixed end 210 is fixed to the base 100, and the movable end 220 is not in contact with the base 100 (as shown in fig. 6).
The deformation part 230 is elastically deformed under the stress, and the movable end 220 is propped against the trigger head 310 of the micro switch 300; the deformation portion 230 returns to elastic deformation, and the movable end 220 is separated from the trigger head 310 of the micro switch 300.
It should be noted that, compared to the conventional belt reminding wearing sensor mentioned in the background art, the belt reminding wearing sensor 20 of the present invention is particularly improved on the movable end 220 of the elastic sheet 200, so that the movable end 220 of the elastic sheet 200 does not make any contact with the base 100 (as shown in fig. 6), and the movable end 220 of the elastic sheet 200 is equivalent to being suspended above the base 100, so that the movable end 220 of the elastic sheet 200 can smoothly reciprocate without obstruction. For example, the movable end 220 of the elastic sheet 200 may be downsized on the basis of a conventional structure while the bottom of the base 100 corresponding to the movable end 220 is hollowed out.
As can be seen from the above, the movable end 220 of the elastic sheet 200 does not contact the base 100, and the movable end 220 of the elastic sheet 200 is suspended above the base 100, and the structural improvement solves the problem that the movable end 220 of the elastic sheet 200 is jammed during the reciprocating movement, but also brings new problems, such as: on the one hand, the elastic restoring force of the entire elastic sheet 200 is greatly reduced, and on the other hand, the movable end 220 of the elastic sheet 200 is easily shaken during the reciprocating movement.
In order to solve the above new problem, the present invention further provides structural improvement, specifically, the seat belt reminder wearing sensor 20 further comprises a cross support guide 400 (as shown in fig. 7) provided on the base 100, wherein the cross support guide 400 comprises a cross reinforcement plate 410 and a longitudinal support guide plate 420 which are cross-connected. Referring to fig. 8, 9 and 10, the edge of the plate surface of the longitudinal supporting guide plate 420 has an arc-shaped supporting guide surface 421, and the plate surface of the longitudinal supporting guide plate 420 is provided with an elastic force enhancing stop block 422.
The deformation portion 230 of the elastic sheet 200 is provided with an elastic guide claw 500 (as shown in fig. 8 and 9), one end of the elastic guide claw 500 is connected to the deformation portion 230, and the other end of the elastic guide claw 500 slides against the arc-shaped supporting guide surface 421 to form a clamping end 510 (as shown in fig. 11). As shown in fig. 11, the clamping end 510 is provided with a clamping groove 511, the clamping end 510 clamps the edge of the board surface of the longitudinal support guide plate 420 through the clamping groove 511, and the clamping end 510 abuts against or is separated from the elastic force enhancing blocking piece 422.
The following analysis illustrates the above structural improvement:
(1) By arranging the cross support guide frame 400, the elastic sheet 200 can be effectively prevented from being unable to recover elastic deformation due to excessive deformation in the elastic deformation process, and when the elastic sheet 200 is elastically deformed to reach the limit position, the elastic sheet 200 is supported by the cross support guide frame 400, so that the elastic sheet 200 is prevented from being excessively deformed;
(2) By adding an elastic guide claw 500 on the deformation part 230 of the elastic sheet 200, the elastic guide claw 500 is matched with the cross support guide frame 400, so that the elastic restoring force of the elastic sheet 200 can be further enhanced;
(3) The other end of the elastic guide claw 500 slides and is held on the arc-shaped supporting guide surface 421 to form a clamping end 510, the clamping end 510 is provided with a clamping groove 511, and the clamping end 510 clamps the edge of the plate surface of the longitudinal supporting guide plate 420 through the clamping groove 511, so that the elastic sheet 200 can move along the preset track of the arc-shaped supporting guide surface 421, the movable end 220 of the elastic sheet 200 is not easy to shake, and the movable end 220 of the elastic sheet 200 can be accurately abutted with the trigger head 310 of the micro switch 300;
(4) The elastic force enhancing stop block 422 is arranged on the board surface of the longitudinal supporting guide board 420, when the elastic sheet 200 is elastically deformed, the clamping end 510 of the elastic guide claw 500 can be abutted against the elastic force enhancing stop block 422, so that the clamping end 510 and the elastic force enhancing stop block 422 generate an abutting force, the abutting force can promote the elastic guide claw 500 to further bend and deform, and accordingly the original elastic restoring force of the elastic guide claw 500 is increased, and then when the elastic sheet 200 returns to elastic deformation, the elastic guide claw 500 can promote the elastic sheet 200 to return to elastic deformation with a stronger elastic restoring force.
In the present invention, the groove wall of the clamping groove 511 has a linear clamping rib 511a (as shown in fig. 11), and the clamping rib 511a abuts against the plate surface edge of the longitudinal supporting guide plate 420. By providing the grip rib 511a on the groove wall of the grip groove 511, the contact area of the groove wall of the grip groove 511 with the plate surface of the longitudinal supporting guide plate 420 is reduced, and the friction force is reduced, so that the grip end 510 of the elastic guide jaw 500 slides more smoothly along the plate surface edge of the longitudinal supporting guide plate 420.
As shown in fig. 10, in the present embodiment, the fixing end 210 is provided with a clamping groove 211, and the base 100 is correspondingly provided with a clamping protrusion 101 matched with the clamping groove 211, and the clamping groove 211 is clamped with the clamping protrusion 101. It will be appreciated that the fixed end 210 of the elastic sheet 200 is fixed to the base 100 by means of a snap-fit connection.
As shown in fig. 10, in the present embodiment, a mounting buckle 102 is provided on a base 100. The base 100 is secured to an external object by the mounting clip 102, thereby achieving the mounting of the entire seat belt reminder wear sensor 20.
In one embodiment, the base 100 and the elastic piece 200 are made of plastic, the base 100 and the elastic piece 200 can be integrally formed by injection molding, and the plastic can effectively save the production cost on the basis of realizing the original functions.
In another embodiment, the base 100 is made of plastic, and the elastic sheet 200 is made of metal. The elastic sheet 200 is made of metal, so that on one hand, the overall mechanical property of the elastic sheet 200 can be further improved, the service life of the elastic sheet is prolonged, and on the other hand, the elastic sheet 200 made of metal is not easy to age and is sticky in the long-time use process, and the sliding smoothness of the elastic sheet can be effectively improved.
As shown in fig. 12, the present invention also discloses an automobile safety seat 30, which includes: the seat body 40 and the seat belt described above alert the wearing sensor 20.
As shown in fig. 12, the seat body 40 has a sponge cushion 41, and the seat belt reminder donning sensor 20 is mounted on the seat body 40 below the sponge cushion 41.

The force-bearing conductive reed 620 is fixed in the frame body of the annular frame 610, and the sponge cushion 41 is attached to the force-bearing conductive reed 620.
One end of the upper half force applying rod 630 is rotatably provided at the edge of the ring frame 610 by a torsion spring (not shown), the other end of the upper half force applying rod 630 extends toward the center of the ring frame 610, the lower half force applying rod 640 is rotatably provided at the edge of the ring frame 610 by a torsion spring (not shown), and the other end of the lower half force applying rod 640 extends toward the center of the ring frame 610.
The force-receiving conductive reed 620 is elastically deformed by force, and the force-receiving conductive reed 620 transmits the force to the upper half force-applying lever 630 or the lower half force-applying lever 640, and the upper half force-applying lever 630 or the lower half force-applying lever 640 rotates and causes the elastic piece 200 of the seat belt reminder wearing sensor 20 to be elastically deformed.
The force-receiving conductive reed 620 returns to elastic deformation without being forced, and the upper half force-applying lever 630 or the lower half force-applying lever 640 is separated from the elastic piece of the seatbelt reminder wear sensor 20.
Next, the car seat 30 having the above-described structure will be described by way of analysis:
(1) By arranging the stress conduction reed 620 below the sponge cushion 41, the sponge cushion 41 can be prevented from being sunken due to direct contact with the deformation part 230 of the elastic sheet 200 of the seat belt reminding wearing sensor 20, and the occurrence of a force application blank area in the background art is avoided, so that the sensitivity of the sensor is improved;

(3) The crews on the automobile leave from the sponge cushion 41, the stress transmission reed 620 returns to elastic deformation and pushes the sponge cushion 41 to reset, the upper half area force application rod 630 or the lower half area force application rod 640 is not reset by the transmission force of the stress transmission reed 620, and the safety belt reminds that the elastic sheet 200 wearing the sensor 20 also returns to elastic deformation;
(4) The force transmission can be realized by only providing one upper half force application rod 630 and one lower half force application rod 640 without providing more force application rods, thereby simplifying the structure.
