Description

Technical Field

[0001] This invention belongs to the field of automotive window breaking technology, specifically relating to a manual window breaking device based on a composite power design. Background Technology

[0002] With the popularization of new energy vehicles, the integration of various vehicle systems and vehicle control systems continues to improve. While this technological trend brings convenience in daily use, it also creates escape hazards in emergency situations. When a vehicle faces emergencies such as falling into water, battery fire, or severe collision, the electrical system is prone to short circuits, sensor failures, or power outages, directly causing the electronically controlled window operation to malfunction. As the core escape route for occupants, the windows may fail to lower properly due to system failure, significantly shortening the golden escape window. Even if some models are equipped with electronic emergency window lowering devices, their operation depends entirely on the vehicle's power supply. Once the circuit is damaged or power is lost, the device becomes ineffective and cannot provide effective assistance for escaping. Summary of the Invention

[0003] The purpose of this invention is to provide a manual window-breaking device based on a composite power design.

[0004] In a first aspect, the present invention provides a manual window-breaking device based on a composite power design, which includes a housing and a cutting mechanism installed inside the housing; the cutting mechanism includes a driving component and an operating component and a limiting component installed on the driving component; the driving component includes a slider, a slide rail, a first vertical plate, a second vertical plate, a slide rod, a moving frame and a first spring;

[0005] The operating component forms a sliding pair with the slide rail via a slider. The movement of the slider on the slide rail drives the operating component to cut the steel cable of the glass lift. The first and second vertical plates are respectively fixed to the bottom ends of the slide rail. The sliding rod is fixedly installed between the first and second vertical plates. One end of the movable frame is fixed to the slider, and the other end is restricted from moving on the sliding rod by a limiting component. The movable frame slides along the sliding rod through a through-hole. A first spring is fixedly connected to the opposite surfaces of the second vertical plate and the movable frame.

[0006] During operation, the cutting mechanism includes a standby state and a cutting state; in the standby state, the limiting component limits the moving frame, causing the first spring to be in a compressed state; at this time, the slider is fixed on the slide rail;

[0007] In the cutting state, the limiting component releases the restriction on the moving frame, and the first spring releases its elastic potential energy; at this time, the slider cuts the steel cable of the glass lift along the slide rail under the action of the first spring.

[0008] Preferably, the drive assembly further includes a pneumatic assembly; the pneumatic assembly includes a drive cylinder, a compressed air tank, a solenoid valve, and a battery; the output end of the drive cylinder is fixedly connected to the operating assembly via a floating joint, and is used to drive the operating assembly to move; the compressed air tank is used to inject compressed gas into the drive cylinder; the solenoid valve is used to control the compressed air tank to inject compressed gas into the drive cylinder; and the battery is used to power the solenoid valve.

[0009] Preferably, the limiting assembly includes a beveled insert, a moving rod, a pull plate, a fixing frame, a second spring, and a traction rope;

[0010] One side of the inclined insert is fitted with an inclined groove on the movable frame, and the other side is fixedly connected to the pull plate via a movable rod; the fixed frame includes an integrally formed limiting plate and a support column; the limiting plate has a through hole for sliding connection with the movable rod; a second spring is fixedly connected to the limiting plate of the fixed frame and the opposite surface of the inclined insert; one end of the traction rope is fixedly connected to the side of the pull plate away from the movable rod, and the other end is led out from the through hole at the bottom of the outer shell.

[0011] Preferably, the limiting component is provided with a micro switch; the micro switch is electrically connected to the solenoid valve and is used to control the on / off state of the solenoid valve.

[0012] Preferably, the micro switch includes a contact plate and a stationary contact assembly; the traction rope passes through the contact plate and the stationary contact assembly respectively, and the contact plate is fixedly connected to the traction rope, while the stationary contact assembly is slidably connected to the traction rope.

[0013] Preferably, the second spring corresponds one-to-one with the moving rod, and the second spring is penetrated by the corresponding moving rod.

[0014] Preferably, the traction rope is also provided with a protective sleeve, one end of which is fixedly connected to the bottom surface of the outer shell.

[0015] Preferably, the outer casing is provided with a mounting plate; the outer casing is fixed to the inside of the vehicle door by the mounting plate; and a cutting window is provided on the side of the outer casing facing the mounting plate.

[0016] Preferably, the operating component includes a fixing plate and a cutting blade; the cutting blade is fixed to the slider by the fixing plate and moves with the slider on the slide rail.

[0017] Preferably, the end of the support column of the fixing frame away from the limiting plate is fixed to the inner wall of the outer shell.

[0018] The beneficial effects of this invention are:

[0019] 1. The drive component in this invention is powered independently by a battery, disconnected from the vehicle's main circuit, thus avoiding device failure due to vehicle malfunction or power outage; the combined power design of compressed air and spring complements each other: when the power is normal, the dual power is superimposed to cope with scenarios such as steel cable obstruction, ensuring cutting force; when the power fails, the spring power starts independently, eliminating the risk of single power source failure, greatly improving the success rate of steel cable cutting, and providing double protection for escape.

[0020] 2. This invention adopts a pull ring trigger design, which requires no professional tools and can be installed in an easily accessible position on the car door. Even the elderly, children and other people with less strength can easily pull it. With just one "pull" action, the lifting steel cable can be cut, ensuring that the car window glass can fall in a short time, buying precious time for people to escape. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2As shown, a manual window-breaking device based on a composite power design includes a housing 1 and a cutting mechanism installed inside the housing 1. Two mounting plates 1-1 are provided on both sides of the housing 1, and the housing 1 is fixed to the inside of the vehicle door via the mounting plates 1-1. A cutting window 1-2 is provided on the side of the housing 1 facing the mounting plates 1-1, facilitating the cutting mechanism to cut the window regulator cable inside the vehicle door through the cutting window 1-2.

[0030] like Figure 3 and Figure 4 As shown, the cutting mechanism includes a drive assembly 2, an operating assembly 3, and a limiting assembly 4 mounted on the drive assembly 2. The drive assembly 2 includes a slider 2-1, a slide rail 2-2, a first vertical plate 2-3, a second vertical plate 2-4, a slide rod 2-5, a moving frame 2-6, a first spring 2-7, and a pneumatic assembly. The operating assembly 3 forms a sliding pair with the slide rail 2-2 through the slider 2-1. The movement of the slider 2-1 on the slide rail 2-2 drives the operating assembly 3 to slide out from the cutting window 1-2 on the outer casing 1, thereby completing the cutting of the glass lift cable. Both ends of the slide rail 2-2 are fixed to the outer casing 1. The first vertical plate 2-3 and the second vertical plate 2-4 are respectively fixed to the bottom ends of the slide rail 2-2. Grooves at the same horizontal height are provided on opposite sides of the first vertical plate 2-3 and the second vertical plate 2-4 for fixing the slide rod 2-5. One end of the movable frame 2-6 is fixed to the slider 2-1, and the other end has a beveled groove. The movement of the movable frame 2-6 on the slide rod 2-5 is restricted by the abutment of the beveled groove with the limiting component 4, thereby restricting the movement of the slider 2-1 and the operating component 3 on the slider 2-1. The movable frame 2-6 has a through hole, through which it slides along the slide rod 2-5. A first spring 2-7 is fixedly connected to the opposite surface of the second vertical plate 2-4 and the movable frame 2-6, and the first spring 2-7 is penetrated by the slide rod 2-5. The first spring 2-7 can be compressed by the movable frame 2-6 to store elastic potential energy, so that when the movable frame 2-6 is freed from the restriction of the limiting component 4, it can slide along the slide rod 2-5 by the elastic force of the first spring 2-7.

[0031] The pneumatic assembly includes a drive cylinder 2-8, a compressed air tank 2-9, a solenoid valve 2-10, and a battery 2-11. One end of the outer wall of the drive cylinder 2-8 is fixedly connected to the outer casing 1, and the output end of the drive cylinder 2-8 is fixedly connected to the operating assembly 3 via a floating joint, used to drive the operating assembly 3 to move towards the cutting window 1-2. The compressed air tank 2-9 is fixed to the inner wall of the outer casing 1, and compressed gas is injected into the drive cylinder 2-8 through a vent pipe. The solenoid valve 2-10 is connected in series in the vent pipe between the drive cylinder 2-8 and the compressed air tank 2-9, used to control the opening and closing of the vent pipe. The battery 2-11 is fixed to the inner wall of the outer casing 1, used to power the solenoid valve 2-10.

[0032] The operating component 3 includes a fixing plate 3-1 and a cutting blade 3-2. The cutting blade 3-2 is fixed to the slider 2-1 by the fixing plate 3-1, and as the slider 2-1 moves on the slide rail 2-2, the cutting blade 3-2 passes through the housing 1 through the cutting window 1-2, thereby cutting the steel cable of the glass lift outside the housing 1.

[0033] In this embodiment, the cutting blade 3-2 is made of tungsten carbide alloy, which has extremely high hardness and wear resistance and can effectively cut steel cables.

[0034] like Figure 5 and Figure 6 As shown, the limiting assembly 4 includes a beveled insert 4-1, a moving rod 4-2, a pull plate 4-3, a fixing frame 4-4, a second spring 4-5, a traction rope 4-6, and a pull ring 4-7. One side of the beveled insert 4-1 fits into the beveled groove on the moving frame 2-6, and the other side is fixedly connected to the pull plate 4-3 through two moving rods 4-2. The fixing frame 4-4 includes an integrally formed limiting plate and two support columns; the limiting plate has two through holes, which are slidably connected to the two moving rods 4-2 respectively. Two second springs 4-5 are fixedly connected to the opposite surface of the limiting plate and the beveled insert 4-1 of the fixing frame 4-4, and the two second springs 4-5 are respectively penetrated by the two moving rods 4-2. Through the second springs 4-5 set between the limiting plate and the beveled insert 4-1, the beveled insert 4-1 can remain embedded in the beveled groove without external force. The ends of the two support columns of the fixed frame 4-4 furthest from the limiting plate are fixed to the inner wall of the outer casing 1, thereby counteracting the elastic potential energy caused by compressing the second spring 4-5. One end of the traction rope 4-6 is fixedly connected to the side of the pull plate 4-3 away from the moving rod 4-2, and the other end is led out from the through hole at the bottom of the outer casing 1 and fixedly installed with a pull ring 4-7. By pulling the pull ring 4-7 downward, the pull plate 4-3 is pulled downward, causing the second spring 4-5 to be further compressed, and the inclined insert 4-1 disengages from the inclined groove. A micro switch 4-8 is fixed to the bottom of one support column of the fixed frame 4-4. The micro switch 4-8 is electrically connected to the solenoid valve 2-10 and is used to control the on / off state of the solenoid valve 2-10. The micro switch 4-8 includes a contact plate and a stationary contact assembly. A traction rope 4-6 passes through both the contact plate and the stationary contact assembly, with the contact plate fixedly connected to the traction rope 4-6 and the stationary contact assembly slidably connected to the traction rope 4-6. This allows the traction rope 4-6 to contact the contact plate when pulled downwards, thus completing the circuit. A protective sleeve 4-9 is also provided on the traction rope 4-6. One end of the protective sleeve 4-9 is fixedly connected to the bottom surface of the outer casing 1, used to restrict the pull ring 4-7, preventing the traction rope 4-6 from being compressed, and providing guidance for the downward pulling of the traction rope 4-6.

[0035] During operation, the cutting mechanism includes a standby state and a cutting state. In the standby state, on the one hand, the beveled insert 4-1 is embedded in the beveled groove on the movable frame 2-6 under the action of the second spring 4-5, so that the first spring 2-7 is in a compressed state; on the other hand, the contact plate and the stationary contact assembly of the micro switch 4-8 are separated, so that the solenoid valve 2-10 is in a closed state; at this time, the slider 2-1 is fixed on the slide rail 2-2, and the cutting blade 3-2 is away from the cutting window 1-2.

[0036] In the cutting state, on the one hand, the inclined insert 4-1 is pulled out of the inclined groove on the moving frame 2-6 under the traction of the traction rope 4-6, releasing the mechanical lock of the first spring 2-7, and the first spring 2-7 releases its elastic potential energy instantly; on the other hand, the contact plate of the micro switch 4-8 contacts the stationary contact assembly, so that the solenoid valve 2-10 is in the open state, and the compressed air in the compressed air tank 2-9 enters the drive cylinder 2-8 through the solenoid valve 2-10, and the drive cylinder 2-8 quickly pushes out the floating joint; at this time, the slider 2-1, under the dual drive of the first spring 2-7 and the drive cylinder 2-8, precisely cuts the glass lift cable along the slide rail 2-2; after the cable is cut, the window glass loses its traction force and falls naturally along the guide rail under its own gravity, so that the window can be opened quickly.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
