Description

Technical Field

[0001] The present invention relates to safety alarm technology, in particular to a vehicle-mounted safety mechanism. Background Art

[0002] With the increase in the number of family cars, the number of children left behind in cars has also increased. Because family cars are well sealed and soundproofed, even children crying and yelling inside the car will not attract the attention of those outside. There are many reasons why children are left in cars, such as when parents forget to attend to other matters or when parents lose the keys after locking the car and are unable to unlock it immediately. Regardless of the reason, children left in cars for an extended period of time often suffer injuries or deaths from suffocation, heatstroke, or dehydration.

[0003] For example, the application publication number is CN216467671U, the application publication date is May 10, 2022, and the name is "A Safety Window Button Action System", which relates to the technical field of automobile accessories, including a car door, the car door is composed of an inner panel and an outer panel, the interior of the car door is provided with a car glass, the upper end of the car door is provided with a car window, the car window is provided with an electric curtain to protect privacy and safety, the lower end of the car window is provided with a switch to control the movement of the electric curtain, and the switch is hidden inside a window breaker. In this utility model, by hiding the window breaker in the switch, it is avoided that the window-breaking tool cannot be found in the event of danger; because the window breaker is hidden in the switch, it can be prevented that children can take out the window breaker to play with it and cause danger; at the same time, the knob can be easily removed, so that the user can replace the window breaker regularly.

[0004] Another example is an invention patent application with application publication number CN113978357A, published on January 28, 2022, titled "A Child In-Vehicle Alarm Device," which relates to the field of safety alarms. Technical features include: a person detection module, located within the vehicle body, for detecting whether a child is trapped inside the vehicle; a voice alarm module, located on the vehicle body, for transmitting a voice alarm to the outside of the vehicle; a window breaking mechanism, comprising at least a housing within the vehicle body and a window breaker within the housing; and a controller electrically connected to the person detection module, the voice alarm module, and the window breaking mechanism. When the person detection module detects a child trapped inside the vehicle, the controller controls the voice alarm module to transmit a voice alarm to the outside of the vehicle and enables the housing to be opened from the outside of the vehicle to access the window breaker.

[0005] In the prior art, when a child is forgotten and left in a vehicle, using a window breaker to break the glass of a vehicle or a ship is one of the common methods. However, whether breaking the window from the inside out or from the outside in, there are certain risks, not only for the person breaking the window but also for the child. When the child is in the vehicle, he may be in a stationary state on a safety seat or in a free movement state. When breaking the window, it is very easy to cause secondary injuries to the child.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-12 As shown, an embodiment of the present invention provides a vehicle-mounted safety mechanism, including an automatic lifting mechanism 1 for controlling the lifting of a vehicle window, and also includes an external control mechanism 2 and an extension member 21 that can forcibly drive the automatic lifting mechanism 1 to work. When a child is stranded, the external control mechanism 2 drives the extension member 21 to extend out of the vehicle body.

[0036] Specifically in this embodiment, the automatic lifting mechanism 1 is a prior art, including a window lifter. The window lifter is common knowledge to those skilled in the art and will not be described in detail here. However, it should be noted that the automatic lifting mechanism 1 generally includes a motor, a worm gear assembly, and a cross-arm lifting assembly or a rope pulley lifting assembly ( Figure 1 : (a) is a structural diagram of a rope-type lifting assembly, whether it is a fork-arm lifting assembly or a rope-type lifting assembly, it can be applied to each embodiment of the present invention. In each embodiment of the present invention, the external control mechanism 2 is connected to the worm gear assembly. The improvement made in the embodiment of the present invention is also an improvement on the worm gear assembly. The worm gear assembly is used to prevent the window from being opened outside the car and has a self-locking function. In the prior art, during normal operation, when the window needs to be lowered, the worm gear assembly is driven by a motor to work, thereby making the cross-arm lifting assembly or the rope-type lifting assembly work and drive the window to lower. In the worm gear assembly, only The worm gear is driven by rotating the worm, but the worm gear cannot actively rotate to drive the worm gear to rotate; the external control mechanism 2 provides another way to drive the worm gear assembly in the automatic lifting mechanism 1 to work. When a child is detected to be trapped in the car, the external control mechanism 2 drives the protruding member 21 to extend out of the car, so that people outside the car can drive the protruding member 21 to move and further operate the external control mechanism 2, and then the external control mechanism 2 drives the worm gear assembly to move to lower the window; the protruding member 21 is painted with a warning color to alert rescuers. In addition, the protruding member 21 is in a shape that is convenient for rescuers to rotate, such as a cross shape.

[0037] In another embodiment provided by the present invention, regarding the position of the protruding member 21, a hole can be opened at a corresponding position of the vehicle door to facilitate the extension of the protruding member 21. However, opening another hole on the vehicle door will affect the appearance of the vehicle and may also make the door interior less closed. Therefore, the relative positions of various components in the vehicle door can be adjusted so that the protruding member 21 is integrated into the vehicle handle. Furthermore, preferably, the keyhole on the door handle is cancelled in mid-to-high-end electric vehicles, and the end of the protruding member 21 can be set at the position of the original keyhole. When the door handle is extended outward, the protruding member 21 extends out of the door handle. In this way, without making any modifications to the white body of the vehicle door, the extension of the protruding member 21 is achieved only by extending the original door handle. In this way, the entire vehicle door is further beautified, the protruding member 21 is integrated with the vehicle door handle, and it also meets the actual needs of reality. It should also be noted that both the outward pull-type vehicle door handle and the hidden vehicle handle can be used in this embodiment.

[0038] In another embodiment provided by the present invention, it also includes a detention detection unit, which is used to detect whether there is a stranded child in the car. It can be a thermal sensing system or an infrared sensing system, etc. The above mechanisms for detecting whether there is a stranded child in the car can be implemented in the existing technology and will not be described in detail here; it also includes a sound alarm unit, which includes a loudspeaker, and the sound alarm unit is used to emit a sound warning to the outside of the car. The sound alarm unit has two alarm modules, the first alarm module is an alarm sound similar to a siren, which is used to guide rescuers to find the accident vehicle, and the second alarm module is a human voice broadcast. The content of the second alarm module is a pre-set rescue behavior guide, which is used to guide the rescuer's rescue behavior so that he can learn and quickly master the above rescue procedure; it also includes a spare battery and P LC controller, the PLC controller is a programmable PLC controller, which is common knowledge for those skilled in the art and will not be elaborated on here. The backup battery is independent of the vehicle power supply system, so that the detention detection unit, the sound alarm unit and the PLC controller can work independently, so that the car can detect whether there is a child stranded in the car even when the car is locked and the power is cut off. In addition, the backup battery is rechargeable. Whenever the car is started, the backup battery can be charged. The backup battery is used to provide power for the detention detection unit, the sound alarm unit and the PLC controller. The detention detection unit and the sound alarm unit are both electrically connected to the PLC controller; in the above embodiment, a plurality of working units that cooperate with the external control mechanism 2 and the protruding member 21 are provided, which can adapt to the working requirements of each embodiment of the present invention.

[0039] In another embodiment provided by the present invention, the vehicle window is generally raised and lowered by a vehicle window lifter. The vehicle window lifter is a prior art, and common vehicle window lifters are generally divided into cross-arm type electric window lifters and rope-type electric window lifters. The automatic lifting mechanism 1 in this embodiment is also included in the vehicle window lifter. The embodiment of the present invention mainly improves the worm gear assembly in the automatic lifting mechanism 1. The automatic lifting mechanism 1 includes a mounting plate 11 fixed in the vehicle door, and a worm gear assembly for driving the vehicle window movement is installed on the mounting plate 11. The worm gear assembly is also used to prevent the vehicle window from being forced to open from the outside. The worm gear assembly includes a worm wheel and a worm threaded together.

[0040] In another embodiment provided by the present invention, the external control mechanism 2 includes a rotating circular plate 22 rotatably mounted on the mounting plate 11. A movable shaft 23 is slidably penetrated through the middle of the rotating circular plate 22. The extending member 21 is formed at one end of the movable shaft 23 away from the worm and worm gear assembly, and the movable shaft 23 can only slide along a direction perpendicular to the rotating circular plate 22, that is, the mounting plate 11. A through groove 24 is formed on one side of the movable shaft 23 away from the worm and worm gear assembly. A U-shaped member 25 is fixedly connected to the rotating circular plate 22. The middle section of the U-shaped member 25 is slidably disposed in the through groove 24. A return spring 26 is connected between the middle section of the U-shaped member 25 and the inner wall of the through groove 24 close to the worm and worm gear assembly. The return spring 26 enables the movable shaft 23 to be reset after extension, and the movable shaft 23 can also rotate following the rotation of the rotating circular plate 22 (which can be achieved by radially mating grooves and protrusions, and the prior art will not be elaborated). A first bevel gear 27 is also fixedly connected to the middle of the rotating circular plate 22. The movable shaft 23 slidably penetrates through the first bevel gear 27. The movable shaft 23 and the first bevel gear 27 can only be slidably connected and cannot rotate relative to each other (which can also be achieved by the same radially mating grooves and protrusions, and the prior art will not be elaborated). That is to say, when the movable shaft 23 rotates, it can drive the first bevel gear 27 to rotate synchronously. A second bevel gear 28 is fixedly connected to the axial end of the worm. The first bevel gear 27 and the second bevel gear 28 are meshed with each other. Through the meshing between the first bevel gear 27 and the second bevel gear 28, the transmission direction of the power is changed, so as to facilitate the extension member 21 to extend perpendicular to the vehicle door and can also reduce the space required when the external control mechanism 2 works. The external control mechanism 2 further includes a push rod 29. An extrusion portion 291 is connected to the push rod 29. The extrusion portion 291 and the movable shaft 23 are arranged in corresponding cooperation, that is, the movable shaft 23 is in the advancing direction of the extrusion portion 291, and in the initial state, there is a certain distance between the two. When the extrusion portion 291 moves axially along with the push rod 29, it can contact the movable shaft 23. The extrusion portion 291 is composed of two opposite frustum-shaped structures, and these two opposite frustum-shaped structures are butt-jointed by circular surfaces with larger diameters. An electric push rod (not shown in the figure) is detachably installed inside the vehicle door. The electric push rod is also electrically connected to the PLC controller. The movable end of the electric push rod is fixedly connected to the push rod 29 to provide power for the movement of the push rod 29.

[0041] In another embodiment provided by the present invention, the extending member 21 is fixedly connected to one end of the movable shaft 23 away from the worm and worm gear assembly, and rotating the extending member 21 can drive the movable shaft 23 to rotate synchronously, thereby driving the external control mechanism 2 outside the vehicle.

[0042] When a child is detected to be stranded in the car and / or the owner's remote control is received, the electric push rod drives the push rod 29 to move to the side close to the worm gear assembly, and the extrusion part 291 moves accordingly and contacts the movable shaft 23, thereby pushing the movable shaft 23 to move outside the car, and also causing the protruding piece 21 to extend out of the car door. At this time, the movable shaft 23 compresses the return spring 26. When the extrusion part 291 squeezes the push rod 29 to the limit position, the rescuer outside the car can rotate the protruding piece 21 and synchronously drive the movable shaft 23 to rotate. The rotation of the movable shaft 23 drives the first bevel gear 27 to rotate, and the rotating circular plate 22 also rotates accordingly. When the first bevel gear 27 rotates, the second bevel gear 28 meshing with it also rotates and drives the worm to rotate, thereby causing the worm wheel to rotate and the car window to drop. In this way, the rescuer outside the car can timely lower the car window and rescue the stranded child.

[0043] In reality, there are many environments that children may encounter when they are stranded in a car. In terms of the environment inside the car, there are two states for children: one is that the child is free to move in the car, and the other is that the child is in a safety seat and cannot move freely. In either state, smashing the car window is not the optimal solution, especially when the child is in the free-moving state. The child may also approach the broken car window because he or she cannot communicate inside and outside the car or cannot understand the rescue process, causing secondary injuries. In terms of the environment outside the car, when an alarm is issued to the outside of the car that a child is stranded in the car, there are also two situations. One is that someone outside the car passes by and can hear the alarm and rescue in time. In this case, the external control mechanism 2 in the above embodiment drives the protruding member 21 out of the car body, and the window can be lowered for rescue by rotating the protruding member 21. This situation also applies to the situation where the parents know that the child is in the car but the key is lost. The second is that there is no one outside the car. At this time, the alarm sound cannot attract rescuers, and the external control mechanism 2 cannot drive the protruding member 21 out of the car body for rescue. At this time, further rescue of the child is required.

[0044] Furthermore, in this embodiment, a self-lowering mechanism 3 is proposed for automatically lowering the window when a child is detected to be trapped in the car when there is no outside rescuer. The self-lowering mechanism 3 is proposed based on the external control mechanism 2. It should be noted that in this embodiment, the push rod 29 and the extrusion portion 291 are slidably connected, and the push rod 29 itself cannot rotate. A clamping block 295 is fixed to the end of the push rod 29 close to the second bevel gear 28, and a sliding groove 292 is provided at the bottom of the push rod 29. The extrusion portion 291 is slidably installed in the sliding groove 292 through a slider 293. A limiting spring 294 is also connected between the slider 293 and the sliding groove 292, and the slider 293 and the limiting spring 294 maintain the The initial position of the extrusion portion 291 on the push rod 29 allows the extrusion portion 291 and the push rod 29 to slide relative to each other with elastic resistance. The elastic coefficient of the limit spring 294 is greater than the elastic coefficient of the return spring 26, so that the extrusion portion 291 can smoothly push the movable shaft 23 to extend. A shift portion 296 is fixed on the mounting plate 11. The shift portion 296 and the extrusion portion 291 are correspondingly arranged, and the shift portion 296 is closer to the second bevel gear 28 than the movable shaft 23; the self-lowering mechanism 3 includes a working chamber opened in the worm, the working chamber passes through one end of the worm close to the second bevel gear 28, and a spiral groove 31 is opened on the inner wall of the working chamber, and the working chamber is away from the second bevel gear 2 A spring rod 32 is rotatably connected to the inner wall of 8, and a moving circular plate 33 is slidably installed on the side of the working chamber close to the second bevel gear 28. The moving circular plate 33 is fixed to the movable end of the spring rod 32, and a clamping groove 34 is provided on the moving circular plate 33. The clamping block 295 and the clamping groove 34 are correspondingly matched. When the clamping block 295 is inserted into the clamping groove 34, the clamping block 295 and the clamping groove 34 can no longer slide relative to each other. A moving block 35 is also fixed on the moving circular plate 33, and the moving block 35 is slidably set in the spiral groove 31; when the sound alarm unit broadcasts a sound warning to the outside for more than a certain time (preferably 5 minutes) and no one drives the external control mechanism 2 to work, the electric The push rod continues to drive the push rod 29 to move toward the side close to the worm gear assembly, so that the engaging block 295 is engaged in the engaging groove 34. The push rod 29 continues to move. At this time, the moving circular plate 33 slides in the working chamber and compresses the spring rod 32. The movement of the moving circular plate 33 drives the moving block 35 to slide in the spiral groove 31. Since the push rod 29 itself cannot rotate, the moving circular plate 33, the moving block 35 and the spring rod 32 cannot rotate either. The push rod 29 drives the spiral groove 31 to move and drives the worm and the spring rod 32 to rotate. The movement of the worm drives the window to drop, so that the interior environment of the car is connected to the outside environment, preventing high temperature or lack of oxygen, and protecting the life safety of stranded children.Based on the external control mechanism 2, two stranded child alarm and rescue modes are provided: a manual rescue mode and an autonomous rescue mode. Of the two modes, the manual rescue mode is still the more effective, allowing the rescuer to promptly transport the child outside the vehicle. These two stranded child alarm and emergency rescue modes can be switched by adjusting the position of the push rod 29. Operation is simple and convenient, and no additional drive is required. Moreover, compared to breaking the vehicle window, this method can be used multiple times in emergency situations, making it safe and efficient.

[0045] In the above embodiment, the two rescue modes are switched by the movement of the push rod 29. The sliding connection between the push rod 29 and the extrusion portion 291 is also to cooperate with the above movement. When it is in the manual rescue mode, the extrusion portion 291 is pressed against the movable shaft 23. When the push rod 29 continues to move and wants to switch to the autonomous rescue mode, the push rod 29 continues to drive the extrusion portion 291 to move. At this time, the movable shaft 23 is reset under the elastic action of the reset spring 26, so that the protrusion 21 is retracted into the vehicle body. This is to prevent the vehicle from being in the autonomous rescue mode. , the window has started to drop and someone outside the car happens to rotate the protruding piece 21, which avoids the parts from being damaged and prevents the person outside the car from rotating the worm in the opposite direction; the push rod 29 continues to move, so that the extrusion part 291 contacts the shift part 296. At this time, the extrusion part 291 can no longer move with the movement of the push rod 29, so that the extrusion part 291 stays between the shift part 296 and the movable shaft 23, avoiding the extrusion part 291 from being pressed into contact with the second bevel gear 28. This is to prevent the extrusion part 291 from pressing against the end of the worm and increasing the resistance to the worm's rotation.

[0046] Furthermore, in the above-mentioned autonomous rescue mode, the car windows are automatically lowered to connect the outside and inside environments. However, the weather environment outside the car at this time is unknown. It may be a high temperature environment, a low temperature environment, or it may be rainy. When encountering the above-mentioned uncertain weather environment, directly connecting the inside and outside environments of the car without the help of rescue personnel is more likely to cause secondary injuries to the stranded children. Especially when the children are stranded in the safety seats and cannot move freely, whether it is sunlight slanting on the children's bodies or rain entering the car on rainy days, it may cause great harm to the children. For this reason, this embodiment proposes a further solution The scheme is to prevent the external environment from causing harm to children when the car window is lowered. In this embodiment, a protective unit 36 is included. The protective unit 36 includes a working groove 361 provided on the mounting plate 11. A limiting member 362 is slidably installed in the working groove 361. A rotating shaft 363 is rotatably penetrated in the middle of the limiting member 362. A torsion spring is sleeved on the rotating shaft 363 and the torsion spring is connected to the limiting member 362 to ensure the initial state of the rotating shaft 363. A driven wheel 364 is fixed to one end of the rotating shaft 363 close to the worm gear assembly. The driven wheel 364 can mesh with the worm gear. In the initial state, the driven wheel 364 The worm gear is not engaged. A connecting rope 365 is wound around one end of the rotating shaft 363 away from the worm gear assembly. A square plate 366 is also fixed to the mounting plate 11. A pop-up rod 368 is connected to the square plate 366 via a connecting spring 367. The pop-up rod 368 is located in the movable gap of the window on the door and fits the inside of the window. The initial state of the connecting spring 367 is a compressed state. A flexible ventilation cloth 369 is connected between the pop-up rod 368 and the square plate 366. The flexible ventilation cloth 369 can prevent most direct sunlight and rain. In the prior art, it can be an open-pore PVC tarpaulin, etc. One end of the connecting rope 365 away from the rotating shaft 363 is fixed to the ejection rod 368. The rotating shaft 363 is also rotatably connected to an elastic rod 370. The elastic rod 370 and the push rod 29 are connected to the same side plate 371. At this time, the movable end of the electric push rod is fixed to the side plate 371, so that the elastic rod 370 and the push rod 29 can move synchronously. In the initial state, the driven wheel 364 is away from the worm gear, the connecting rope 365 is wound around the rotating shaft 363, and under the elastic action of the connecting spring 367, the torsion spring cannot rotate. That is, in the initial state, the ejection rod 368 is close to the square plate 366.When the child is detected to be trapped in the car, the electric push rod is started by the PLC controller to push the side plate 371 to move in the direction close to the worm gear assembly. At this time, the protruding piece 21 gradually pops out of the car door. At the same time, the elastic rod 370 pushes the rotating shaft 363 to move, so that the limiting piece 362 moves in the working groove 361 in the direction close to the worm gear assembly, and the driven wheel 364 also moves accordingly. When the protruding piece 21 moves to the extreme position, the driven wheel 364 also meshes with the worm wheel. When the rescuer outside the car rotates the protruding piece 21, the worm moves and drives the worm wheel to rotate accordingly. At this time, the car window is lowered. At the same time, the rotation of the worm wheel also drives the driven wheel 364 to rotate in the direction of loosening the connecting rope 365, so that the connecting rope 365 gradually enters a relaxed state. Since the connecting spring 367 is in a compressed state, the connecting spring 367 gradually pops out, thereby pushing the car window. The movable pop-up rod 368 gradually pops out from the movable gap of the window, so that the pop-up rod 368 gradually drives the flexible ventilation cover 369 to straighten. Overall, the window gradually descends but the flexible ventilation cover 369 gradually rises. When the window is completely retracted into the movable gap of the window, the flexible ventilation cover 369 covers at least part of the original window position. When entering the autonomous rescue mode, the electric push rod continues to move and pushes the side plate 371 to move. At this time, the elastic rod 370 is compressed, and the driven wheel 364 The worm gear remains meshed with the worm gear. Repeating the above steps will completely cover the window at its original position. Thus, when the window is lowered, the flexible ventilation curtain 369 provides a preliminary barrier between the interior and exterior environments of the vehicle, preventing secondary injuries to children caused by high or low temperatures or rainy weather. Furthermore, in both rescue modes, the flexible ventilation curtain 369 can be raised simultaneously with the window lowering. The flexible ventilation curtain 369 is also easily damaged and will not hinder further rescue efforts.

[0047] More preferably, the flexible ventilation cover 369 is provided with warning colors and warning words to remind subsequent rescuers.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
