In the present invention, the triggering unit 120 may be a mechanical switch, a pressure sensor, a contact sensor, or the like, but not limited thereto, and other components may be used as the triggering unit 120.
Referring now further to fig. 4-8, in one embodiment of the present invention, the trigger unit 120 is a mechanical switch mounted in the seat 200 below the tightening strap 240, and the mechanical switch 120 is electrically connected to the power circuit of the prompting device 130 by a wire, and is operable to close the mechanical switch when the shoulder strap 210 is tightened, thereby conducting the power circuit of the prompting device 130 to alarm.
Referring to fig. 4-6, the shoulder strap tightening reminder device 100 further includes a driving unit 150, which is installed in the seat 200 and cooperates with the tightening strap 240 and the mechanical switch 120, and the driving unit 150 can be driven to act on the mechanical switch 120 during tightening of the tightening strap 240.
Specifically, the driving unit 150 includes a movable pin 151, a reset member 152, and a positioning rod 153, the movable pin 151 is slidably connected in the seat 200, the positioning rod 153 is fixed below the movable pin 151, the positioning rod 153 and the movable pin 151 are coaxially disposed, and two ends of the reset member 152 are respectively abutted against the movable pin 151 and the positioning rod 153; the movable pin 151 has a first position and a second position opposite to each other, the movable pin 151 is located at the first position when the tightening strap 240 is in a relaxed state, the movable pin 151 is driven to slide from the first position to the second position when the tightening strap 240 is tightened, the movable pin 151 acts on the mechanical switch 120 to close the mechanical switch, the restoring member 152 is deformed by acting on the mechanical switch, and the elastic force generated by the restoring member 152 constantly has a tendency to move the movable pin 151 from the second position to the first position.
Preferably, the restoring member 152 is a torsion spring, and both ends thereof are fixed to the movable pin 151 and the positioning rod 153, respectively, and of course, the restoring member 152 is not limited to the torsion spring, and other elastic members may be used.
With continued reference to fig. 4-6, the shoulder strap tensioning prompting device 100 further includes a mounting bracket 160 secured within the seat 200 for mounting the shoulder strap tensioning prompting device 100. Specifically, the fixing seat 160 has two opposite wings 161, an accommodating space is formed between the two wings 161, parallel sliding grooves 162 are formed on the two wings 161, the sliding grooves 162 are preferably in an arc structure, two ends of the movable pin 151 are respectively connected in the two sliding grooves 162 in a sliding manner, the positioning rod 153 is fixed on the two wings 161 and is positioned below the movable pin 151, one end of the torsion spring is fixed on the positioning rod 153, and the other end of the torsion spring acts on the movable pin 151; in addition, the mechanical switch 120 is accommodated in the accommodating space of the fixing base 160 and is located below the movable pin 151. The tightening strap 240 is inserted into the fixing seat 160 and is pressed against the movable pin 151, when the tightening strap 240 is pulled along the direction indicated by the arrow F1 in fig. 6, it will exert a force on the movable pin 151 to drive the movable pin 151 to slide along the sliding groove 162, that is, to make the movable pin 151 slide from a first position at one end of the sliding groove 162 to a second position at the other end in the direction indicated by the arrow F2 in fig. 6, in this process, the movable pin 151 gradually acts on the mechanical switch 120 to close it, and at the same time, presses the torsion spring to deform it; when the tightening strap 240 is loosened, the elastic force of the torsion spring drives the movable pin 151 to slide from the second position to the first position, so that the mechanical switch 120 loses the acting force to be disconnected.
It should be understood that the trigger signal is not limited to being generated by a mechanical switch, for example, a pressure sensor may be installed on the fixing base 160, which is installed under the tightening strap 240 to detect the pressure applied thereto by the tightening strap 240, and a relay switch is provided on the power supply circuit of the prompting device 130, and when the pressure value detected by the pressure sensor reaches a preset value, the control unit 111 turns on the relay switch according to the detection signal of the pressure sensor, and turns off the relay switch when it does not receive the signal of the pressure sensor, thereby controlling the prompting device 130 to alarm.
The principle of the shoulder belt tightening reminder 100 will now be described with reference to fig. 1-8 again, taking the adjustment of the shoulder belt 210 of the child safety seat 1 of the present invention as an example.
When the shoulder strap 210 needs to be adjusted, the locking assembly 250 is operated to release the lock, then the shoulder strap 210 can be pulled to adjust the tightness, after the adjustment is completed, the tightening strap 240 is pulled to keep the shoulder strap 210 in a tightened state, during the process that the tightening strap 240 is pulled, the movable pin 151 is acted to slide along the sliding groove 162 (the direction indicated by the arrow F2 in fig. 6), after the tightening strap 240 is pulled, the movable pin 151 slides to the second position to act on the mechanical switch 120 to close the mechanical switch, so that the power supply loop of the prompting device 130 is conducted to send out or light or alarm sound or both to prompt the user that the tightening strap 240 is pulled, and after the prompting device 130 continuously sends out a prompting signal for a few seconds, the control unit 111 controls the prompting device 130 to close. The tensioned tightening strap 240 may be secured by a locking assembly 250.
In the sliding process of the movable pin 151, the reset member 152 (i.e., the torsion spring) is pressed to generate deformation, when the tightening strap 240 is loosened, the movable pin 151 loses acting force, the reset member 152 recovers the deformation to drive the movable pin 151 to reset, and then the movable pin 151 loses acting force on the mechanical switch 120 to open the mechanical switch, until the next time the mechanical switch 120 is closed, the prompting device 130 alarms again.
In summary, since the shoulder strap tightening reminder 100 of the present invention has the trigger unit 120 disposed on the adjusting path of the tightening strap 240 and the reminder 130 exposed on the surface of the child safety seat 1, and both the reminder 130 and the trigger unit 120 are electrically connected to the main circuit board 110, when the tightening strap 240 is tightened, the trigger unit 120 can be acted on to generate a trigger signal, and the control unit 111 on the main circuit board 110 controls the reminder 130 to alarm according to the trigger signal, so as to remind the consumer that the shoulder strap 210 is tightened, thereby the tightening degree of the shoulder strap 210 in use can be reminded and meet the design standard and requirement, the standardization and standardization of the use of the safety strap are promoted, the safety performance is improved, and the riding comfort of the child can be ensured.
Correspondingly, the child safety seat 1 with the shoulder belt tightening reminder device 100 of the invention also has the same technical effect.
The construction of the other parts of the child safety seat 1 according to the invention is conventional in the art and will not be described in detail here.
The foregoing description of the preferred embodiments of the present invention is not intended to limit the scope of the claims, which follow, as defined in the claims.
