Description

Technical Field

[0001] This utility model relates to the technical field of child seat adjusters, specifically an adjustment device with a seat belt tension reminder function. Background Technology

[0002] As a crucial piece of equipment for ensuring children's safety while traveling in vehicles, the reliability of the child safety seat's restraint system is paramount. The tether system, as one of the anti-rollover devices, requires adjustment during installation to tighten the seatbelt and ensure the seat is securely fixed to the car seat. Currently, various devices are available for adjusting the seatbelt tension.

[0003] Patent CN211969235U discloses a child safety seat adjuster. This device uses the deformation of an elastic-plastic material to move the display area, displaying a color change in the first display window to indicate whether the seat belt is tensioned. This solution has a simple structure and judges tension solely through visual feedback, thus improving the intuitiveness and convenience of installation to a certain extent.

[0004] However, as users' demands for operational safety and perceived reliability continue to increase, relying solely on visual cues still has certain limitations. For example, in low light or obstructed vision, users may have difficulty accurately judging color changes, which could affect the correct tension of the seatbelt.

[0005] Based on this, an adjustment device with a seat belt tension reminder function is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

The feature is that: the outer shell is further equipped with a sound-generating module controlled by a sliding component. When the seat belt is not tensioned, the sliding component slides to a state where it is separated from the sound-generating module, and the sound-generating module emits a prompt sound; when the seat belt is tensioned, the sliding component is driven to slide in the outer shell to a state where the sound-generating module is triggered, and the sound-generating module shuts off.

[0008] Preferably, the sound-generating module has a sound-generating component and a trigger switch, and the sliding component controls the trigger switch by sliding.

[0009] Preferably, the sliding component is provided with an integrally formed elastic arm, which is used to slide with the sliding component to a compressed and deformed state when the seat belt is in a tensioned state, and to drive the sliding component to return to its original position when the seat belt is in a de-tensioned state.

[0010] Preferably, the sound-generating module further includes a power switch for power supply control of the sound-generating module.

[0011] Preferably, the sliding assembly further includes a red display block and a green display block, and a viewing window is provided on the housing. When the seat belt is not tensioned, the red display block on the sliding assembly moves to the viewing window with the sliding assembly. When the seat belt is tensioned, the green display block on the sliding assembly moves to the viewing window with the sliding assembly. The red display block or the green display block can be seen through the viewing window.

[0012] Preferably, the size of the visible window is smaller than the red and green display blocks.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, this utility model discloses an adjustment device with a seat belt tension reminder function, which has both visual and voice prompt functions. In the patent document with announcement number CN211969235U and titled "A Child Safety Seat Adjuster", an implementation structure with a visual prompt function is disclosed. This embodiment can adopt the above-disclosed structure or the structure disclosed in this embodiment.

[0027] An adjustment device with a seat belt tension reminder function includes a housing consisting of an outer shell 100 and a back plate 500. The outer shell 100 and the back plate 500 are fixedly connected by screws 600. The upper end of the outer shell 100 is provided with two upper pull strap mounting ports 103 spaced apart vertically. The lower end of the outer shell 100 is provided with a second mounting port 104 for passing a lower pull strap 800. The top of the outer shell 100 in front of the upper pull strap mounting ports 103 is provided with a button socket 101 for mounting a button 200. The button 200 is slidably inserted into the button socket 101. The front of the button 200 is provided with a protrusion. The back of the button 200 is fixedly mounted with a sliding rod 204. The sliding rod 204 is fixedly mounted on the back of the button 200, that is, fixed in the receiving space formed by the protrusion. The receiving space provides space for the upper pull strap to pass through the sliding rod 204. The center of the front of the button 200 is provided with an upper slot 201 for mounting a reset spring. Two first sliding grooves 202 are symmetrically provided on both sides of the upper slot 201.

[0028] A sound-emitting module 300 is provided between the button 200 and the housing 100. A protective plate 303 is connected to the front of the sound-emitting module 300. The sound-emitting module 300 is fixedly installed in the housing 100 by a mounting plate 304 located on the back. The mounting plate 304 is fixedly installed in the housing 100. A lower slot 305 is provided at the middle position of the back of the mounting plate 304, which corresponds to the upper slot 201. A return spring is fixed between the upper slot 201 and the lower slot 305. The return spring is used to provide an upward return force for the button 200. Two first limiting blocks 306 are symmetrically provided on the mounting plates 304 on both sides of the lower slot 305. The first limiting blocks 306 correspond one-to-one with the first sliding grooves 202 and are set in the corresponding first sliding grooves 202. The button 200 slides and engages with the first limiting blocks 306 on the mounting plate 304 through the first sliding grooves 202. The first limiting blocks 306 limit the button 200 in the housing 100 and limit the range of vertical movement of the button 200.

[0029] A sliding module 400 that moves up and down is provided on the lower side of the front side of the button 200. The sliding module 400 includes a frame 401. The frame 401 is provided with a square hole 402 for the pull-down strap to pass through. The lower end of the frame 401 is provided with an elastic arm 403 integrally formed with the frame 401. The middle part of the mounting plate 304 is provided with a second slide groove 307 on both sides. The upper end of the frame 401 is provided with a trigger block 404 that protrudes forward and slides in the second slide groove 307. The front end of the trigger block 404 extends out of the mounting plate 304 and is connected to a mounting bracket 407. A green display block 406 and a red display block 408 arranged vertically are mounted on the mounting bracket 407. The front of the housing 100 is provided with two viewing windows 102 that cooperate with the corresponding red display block 408 and green display block 406. The size of the green display block 406 and red display block 408 is larger than the corresponding viewing windows 102. The lower two sides of the mounting plate 304 are also provided with second limiting blocks 310. The second limiting blocks 310 are located outside the frame 401 and are used to limit the sliding module 400 in the left and right directions.

[0030] The sound-generating module 300 includes a main control chip 312, a power supply 311, and a sound-generating component 309 (which may be, but is not limited to, a buzzer or a horn; in this embodiment, an alarm is used) mounted on a circuit board 308 on one side of the sound-generating component 309. A trigger switch 301 is mounted on the circuit board 308 on one side of the sound-generating component 309. The trigger switch 301 may be, but is not limited to, a micro switch or a limit switch. A power switch 302 is mounted on the circuit board on the other side. The trigger end of the trigger switch 301 protrudes from the circuit board and is located on the running trajectory of the trigger block 404 on the same side. This is used when the seatbelt is not tensioned. When the seat belt is in the tensioned state, the button 200 is in the upper position under the action of the reset spring, and the trigger block 404 of the sliding module 400 is separated from the trigger end of the trigger switch 301 under the action of the elastic arm 403. The sound module emits a prompt sound, and the red display block 408 can be observed through the viewing window 102. When the seat belt is in the tensioned state, it drives the trigger block 404 of the sliding component 400 to slide in the housing 100 to the trigger end of the trigger switch 301. The sound of the sound component 309 is turned off, and the green display block 406 can be observed through the viewing window 102.

[0031] like Figure 9As shown, the positive and negative terminals of the power supply 311 are connected to the power supply interface of the main control chip 312. The negative terminal of the sound-generating component 309 and one end of the trigger switch 301 and power switch 302 are connected to the negative terminal of the power supply 311. The positive terminal of the sound-generating component 309 and the other end of the trigger switch 301 and power switch 302 are respectively connected to the control terminal of the main control chip 312. The circuit achieves a closed-loop function through "power supply 311 provides power → power supply 311 triggers → power supply 311 processes → sound-generating component 309 alarms". In the circuit, the power supply 311 provides DC power to the entire circuit and is the energy source of the system. The power switch 302 controls the overall power supply of the circuit through switching on and off, realizing the "on / off" function and avoiding power consumption during long standby. The main control chip 304 is the core control unit of the circuit, responsible for receiving the signal from the trigger switch 301 and executing preset logic: when the trigger switch 301 is triggered, the main control chip detects the signal change of the trigger switch 301 and controls the sound-generating component 309 to stop emitting sound.

[0032] The back panel 500 is a flat plate with a window in the middle, which is the same as the back panel structure disclosed in CN211969235U. The upper end of the back panel 500 is provided with an upper pull strap fixing part 501, and two side plates 502 are symmetrically provided on both sides of the back panel 500. The lower end of the back panel 500 is provided with screw holes 503 for mounting screws 600. The side plates 502 of the back panel 500 can be inserted into the outer shell 100.

[0033] One end of the pull strap is fixed to the child safety seat, and the other end is free. It first passes through one of the pull strap mounting holes 103, then around the sliding bar 204, and then through the gap between the sliding bar 204 and the pull strap fixing part 501 of the back panel 500. Finally, it comes out through the other pull strap mounting hole 103. It can be seen that the size of the gap between the sliding bar 204 and the pull strap fixing part 501 is the key to whether the free end of the pull strap can move freely. This part of the structure is the same as the corresponding structure of a child safety seat adjuster disclosed in CN211969235U, and will not be described in detail here.

[0034] The pull-down strap enters from the lower part of the window of the back panel 500, passes through the square hole 402 of the frame 401, and exits from the second mounting port 104.

[0035] The principle and usage method of this embodiment are as follows: (1) In the initial state, both the upper and lower pull straps are in a slack state, and the button 200 of the adjustment device is not pressed; (2) To fix the child safety seat to the car seat, first press the power switch 302 to turn on the circuit of the sound module 300, and then tighten the pull strap through the adjuster. When the pull strap is tightened, the external force of the pull strap 800 on the sliding rod 400 causes the sliding rod 400 to slide down and squeeze the elastic arm 403 until the trigger block 404 squeezes the trigger switch 301, which disconnects the circuit of the sound module 300 and turns off the sound of the sound module 300. Then stop tightening the pull strap. If the sound module 300 does not make a sound, it means that the adjuster has been tightened. At this time, the upper pull strap 700 is squeezed and locked by the movable plate 204 and the upper pull strap locking part 501. If the sound module 300 makes a sound, it means that the adjuster has not been tightened. It is necessary to continue to apply external force to tighten the pull strap until the sound module 300 stops making a sound after the external force is removed. Then the adjustment is completed.

[0036] (3) If you need to relax the child safety seat, the unlocking process is as follows: Press button 200 to make the movable plate 204 drive the pull strap 700 to move downward and disengage from the pull strap locking part 501, thereby releasing the lock on the pull strap 700. At this time, under the action of the elastic arm 403, the trigger block 404 leaves the trigger switch 301, and the sound module 300 will sound again, indicating that the regulator has been released and the regulator has returned to its initial state.

[0037] The above embodiments disclose an adjustment device with a seat belt tension reminder function. By integrating a sound module 300 between the button 200 and the housing 100, and linking the displacement of the sliding rod 400 to achieve sound / silence switching, a dual auditory and visual reminder of whether the seat belt is tensioned is achieved, which significantly improves the safety and reliability of use in low light or obstructed vision scenarios.

[0038] When the adjustment device is in the untightened state, the sliding rod 400 is separated from the sound module 300, and the sound module 300 will emit an audible warning. At the same time, the red display block 408 can be observed through the viewing window 102. When the adjustment device is in the tightened state, the sliding rod 400 is displaced under the external force of the pull-down strap, causing the trigger block 404 to press the trigger switch 301, which disconnects the circuit of the sound module 300, thereby switching the sound module 300 to the mute module. At this time, the green display block 406 can be observed through the viewing window 102.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
