[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Embodiment 1

[0030] As attached Figure 1 To Attachment Figure 8 As shown, the present invention provides a self-rescue and recoverable glass lifter structure under emergency conditions, including a vehicle door 1, a lifting assembly 2 is arranged on the vehicle door 1, wherein the lifting assembly 2 drives the vehicle glass 4 to realize the lifting function, the lifting assembly 2 is connected to the power assembly 3, wherein the power assembly 3 drives the lifting assembly 2 to work, the lifting assembly 2 is connected to the vehicle glass 4, and the lifting assembly 2 is provided with a self-rescue assembly 5, wherein the self-rescue assembly 5 is used to separate the power assembly 3 and the lifting assembly 2, so that the power assembly 3 no longer self-locks the lifting assembly 2, at this time, relying on the dead weight of the vehicle glass 4 or manually pulling the vehicle glass 4 downward to achieve the purpose of opening the vehicle window, the self-rescue assembly 5 is connected to the limiting assembly 6, wherein the limiting assembly 6 is used to limit the self-rescue assembly 5 to avoid the self-rescue assembly 5 from resetting during the process of opening the vehicle window;

[0031] The power assembly 3 includes a synchronous gear 301. When the reel 501 is reset, if it is not aligned with the synchronous gear 301, the DC motor 302 drives the synchronous gear 301 to rotate, so that the synchronous gear 301 and the reel 501 are aligned, and the sleeve is reset;

[0032] The self-rescue assembly 5 includes a reel 501 sleeved with a synchronous gear 301, wherein a tooth groove matching the synchronous gear 301 is provided on a side of the sleeve 601 close to the synchronous gear 301, and a lifting wedge 502 is provided on one side of the reel 501, wherein the lifting wedge 502 is provided with an inclined surface, the inclined surface faces the reel 501, and the lifting wedge 502 is connected to a flexible shaft 503, and the flexible shaft 503 is connected to a handle 504, and pulling the handle 504 will pull the flexible shaft 503, and then the flexible shaft 503 will pull the lifting wedge 502. Lift the wedge block 502 to lift the reel 501, so that the reel 501 is separated from the synchronous gear 301. An elastic sheet 505 is attached to the other side of the reel 501. When the reel 501 is separated from the synchronous gear 301, the reel 501 squeezes the elastic sheet 505. At this time, the elastic sheet 505 is deformed by force and accumulates energy to prepare for driving the reel 501 to reset. The elastic sheet 505 is connected to a mounting frame 506, wherein the mounting frame 506 provides support for the installation of the elastic sheet 505.

[0033] As can be seen from the above, by pulling the handle 504 to pull the flexible shaft 503, the flexible shaft 503 is forced to pull the lifting wedge block 502 to move, and the limit assembly 6 will limit the pulled-out handle 504 to prevent the elastic sheet 505 from driving the reel 501 to reset during the process of opening the window. The lifting wedge block 502 drives the reel 501 to move through the inclined surface during the movement, so that the reel 501 is separated from the synchronous gear 301. At this time, the elastic sheet 505 is squeezed and deformed by the reel 501 to accumulate energy. After the step gear 301 is disengaged, the power assembly 3 is no longer self-locked to the lifting assembly 2, and the deadweight of the vehicle glass 4 will make the lifting assembly 2 move. The vehicle glass 4 can also be manually pulled down to move the vehicle glass 4 down. At this time, the driver and passengers can escape through the car window; during the later recovery, the limit assembly 6 is restored to its original state, and the restriction of the limit assembly 6 on the handle 504 is released. At this time, the elastic sheet 505 is restored to its original state and pushes the reel 501 to approach the synchronous gear 301, so that the reel 501 and the synchronous gear 301 are re-sheathed together.

[0034] Embodiment 2

[0035] As attached Figure 5 To Attachment Figure 6 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the self-rescue component 5 also includes a ball 507 arranged on the lifting wedge 502, wherein the ball 507 is used to reduce the friction between the lifting wedge 502 and the reel 501, the ball 507 is in contact with the reel 501, and the lifting wedge 502 is slidably connected to a slide rail 508, which assists the lifting wedge 502 in stable movement.

[0036] As attached Figure 7 To Attachment Figure 8As shown, specifically, the limiting component 6 includes a sleeve 601 fixedly connected to the vehicle door 1, wherein the sleeve 601 extends from the inside of the vehicle door 1 to the vehicle interior space, and the handle 504 is slidably connected to the sleeve 601. When the handle 504 is pulled, the handle 504 will be pulled out from the sleeve 601, and a storage groove 602 is provided on the peripheral side of the handle 504. The storage groove 602 is rotatably connected to a baffle 603. The storage groove 602 is provided with a receiving groove 604, and a limiting spring 605 is fixedly connected in the receiving groove 604. The limiting spring 605 is fixedly connected to the baffle 603. When the handle 504 is pulled out from the sleeve 601, the limiting spring 605 will push the baffle 603 to rotate, and then the baffle 603 will open. At this time, the baffle 603 is blocked at the end of the sleeve 601, so that the handle 504 cannot return to the sleeve 601.

[0037] As can be seen from the above, the handle 504 is pulled out from the sleeve 601. When the sleeve 601 is separated from the receiving groove 604, the limit spring 605 will push the baffle 603 to rotate, and then the multiple baffles 603 will open. After the baffles 603 are opened, the volume of the handle 504 is larger than the inner diameter of the sleeve 601, so that the handle 504 cannot return to the sleeve 601. At the same time, the handle 504 will pull the flexible shaft 503, and then pull the lifting wedge 502 to move along the slide rail 508. During the movement of the lifting wedge 502, the ball 507 rolls to reduce the lifting wedge. The friction between the block 502 and the reel 501 is eliminated, and the wedge block 502 is lifted and driven to move the reel 501 through the inclined surface, so that the reel 501 is separated from the synchronous gear 301; during the later recovery, the baffle 603 is turned back into the storage groove 602, and the limit spring 605 is located in the accommodating groove 604, and then the handle 504 is placed in the sleeve 601, the soft shaft 503 is no longer pulled, and the elastic sheet 505 returns to its original state to push the reel 501 closer to the synchronous gear 301, so that the reel 501 and the synchronous gear 301 are re-sheathed together.

[0038] Embodiment 3

[0039] As attached Figure 3 To Attachment Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that the power assembly 3 also includes a DC motor 302, the DC motor 302 is connected to a worm 303, the worm 303 is connected to a worm wheel 304, the DC motor 302 drives the worm 303 to rotate, and then drives the worm wheel 304 to rotate, the worm wheel 304 is fixedly connected to the synchronous gear 301, and when the synchronous gear 301 is sleeved with the reel 501, the self-locking properties of the worm wheel 304 and the worm 303 prevent the vehicle glass 4 from driving the lifting assembly 2 to move downward due to its own weight.

[0040] In order to increase the service life of the worm wheel 304 and the worm 303, a protective shell is provided, the synchronous gear 301 extends out of the protective shell, the DC motor 302 and the protective shell are arranged in the vehicle door 1, and the mounting frame 506 and the slide rail 508 are arranged on the protective shell.

[0041] As attached Figure 3 As shown, specifically, the lifting assembly 2 includes a guide rail 201 arranged in the vehicle door 1, the guide rail 201 is provided with a pulley 202, the pulley 202 is wound with a rope 203, the pulley 202 assists the rope 203 to move, the rope 203 is connected to the lifting block 204, and the rope 203 moves to drive the lifting block 204 to move.

[0042] As attached Figure 3 As shown, further, both ends of the rope 203 are wound around the drum 501, and the power component 3 drives the drum 501 to rotate through the synchronous gear 301, and then the drum 501 reels or releases the rope 203, and the car glass 4 is fixed on the lifting block 204. When the rope 203 moves, it lifts and lowers the car glass 4 through the lifting block 204.

[0043] As can be seen from the above, the DC motor 302 drives the worm 303 to rotate, the worm 303 drives the worm wheel 304 to rotate, the worm wheel 304 drives the synchronous gear 301 to rotate, the synchronous gear 301 drives the drum 501 to rotate, and then the rope 203 is retracted and released. During the retraction and release, the rope 203 will drive the lifting block 204 to rise or fall, and then the vehicle glass 4 will be lifted and lowered. When the synchronous gear 301 is connected with the drum 501, the self-locking properties of the worm wheel 304 and the worm 303 are used to prevent the vehicle glass 4 from moving the lifting assembly 2 downward due to its own weight. When the synchronous gear 301 is separated from the drum 501, the vehicle glass 4 opens the window due to its own weight and causes the lifting assembly 2 to work in reverse. At this time, the driver and passengers can escape through the window.
