Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

As shown in FIGS. 1 to 12 , an energy-saving emergency lamp with a self-generating function described in this embodiment includes a lampshade 1, which is made of a transparent material and is in a long tubular shape. A mechanical energy storage component is installed at one end of the lampshade 1; a light-emitting component is installed in the lampshade 1, and the light-emitting component is electrically connected to the mechanical energy storage component;

The mechanical energy storage assembly includes an energy storage seat 21, a rotating sleeve 22 rotatably arranged on the outer wall of the energy storage seat 21, a rotating disk 23 rotatably arranged in the rotating sleeve 22, a chuck 24 arranged on the energy storage seat 21 and located in the rotating sleeve 22, and a winding 25 circumferentially arranged on the inner wall of the energy storage seat 21; a volute spring 262471 is connected between the chuck 24 and the rotating sleeve 22, and a permanent magnet 27 corresponding to the winding 25 is circumferentially arranged on the rotating disk 23;

The mechanical energy storage assembly includes an energy storage seat 21, a rotating sleeve 22 rotatably mounted on the outer wall of the energy storage seat 21, a turntable 23 rotatably mounted in the rotating sleeve 22, a chuck 24 mounted on the energy storage seat 21 and located in the rotating sleeve 22, and a winding 25 circumferentially mounted on the inner wall of the energy storage seat 21; a volute spring 262471 is connected between the chuck 24 and the rotating sleeve 22, and a permanent magnet 27 corresponding to the winding 25 is fixedly mounted on the turntable 23 along the circumferential direction.

Specifically, when the energy-saving emergency light of the present embodiment needs to power the light-emitting component through a mechanical energy storage component, the user rotates the rotating sleeve 22 clockwise, and relative movement occurs between the rotating sleeve 22 and the chuck 24, so that the spiral spring 262471 is tightened to store energy. When the spiral spring 262471 is completely wound, the torque on the rotating sleeve 22 is released, and the spiral spring 262471 releases energy, driving the rotating sleeve 22 to rotate counterclockwise relative to the energy storage seat 21, and the rotating sleeve 22 drives the turntable 23 to rotate, and the turntable 23 drives the permanent magnet 27 to rotate relative to the winding 25. The winding 25 cuts the magnetic flux lines to generate electrical energy to power the light-emitting component. The structure is more flexible to use, and is therefore suitable for occasions with high flexibility of use and for use in situations where there is no external light condition.

It should be noted that, as shown in FIG1 , a power supply component electrically connected to the light-emitting component is provided at the other end of the lampshade 1, and the light-emitting component is arranged between the power supply component and the mechanical energy storage component. In this way, the light-emitting component can be powered by the power supply component and the mechanical energy storage component together, or the mechanical energy storage component can be used to charge the power supply component, and then the power supply component outputs electrical energy to the light-emitting component to drive the light-emitting component to work; thereby improving the endurance of the emergency light to meet the needs of emergency lighting for a longer period of time, and saving energy and protecting the environment.

Specifically, as shown in Figure 3, the power supply assembly includes a battery compartment 41 and a power supply battery 42 arranged in the battery compartment 41. One side of the battery compartment 41 is fixedly connected to the lampshade 1, and the other side of the battery compartment 41 is provided with an end cover 43; this arrangement facilitates the replacement and maintenance of the power supply battery 42.

As shown in Fig. 2, Fig. 4 and Fig. 5, the energy-saving emergency light described in this embodiment, in some embodiments, a rotating shaft 221 is convexly provided inside the rotating sleeve 22, a receiving groove is concavely provided at one end of the energy storage seat 21, a rotating disk 23 is fixedly sleeved on the outer wall of the rotating shaft 221 and is located in the receiving groove, a winding 25 is arranged on the groove wall of the receiving groove, a chuck 24 is fixedly installed at the opening position of the receiving groove, an inner end of a spiral spring 262471 is connected to the rotating shaft 221, and an outer end of the spiral spring 262471 is movably engaged with the chuck 24. In this embodiment, the receiving groove is provided to facilitate the installation of the winding 25, and the structure is more compact, and the rotating shaft 221 is provided to facilitate the installation of the rotating disk 23.

As shown in Figures 5 and 6, the energy-saving emergency light described in this embodiment, in some embodiments, a first slide groove 231 extending radially is circumferentially provided on the side of the turntable 23 facing away from the chuck 24, and a first inclined surface 232 is provided at the bottom of the first slide groove 231, and the lower end of the first inclined surface 232 is close to the center of the turntable 23; a centrifugal slider 233 is slidably installed in the first slide groove 231, and the centrifugal slider 233 is provided with a second inclined surface 234 adapted to the first inclined surface 232; when the centrifugal slider 233 slides outward under the action of centrifugal force, it can slide to contact the bottom of the first slide groove 231.

Specifically, when it is necessary to power the light-emitting component through the mechanical energy storage component, the rotating sleeve 22 is rotated clockwise, and relative movement occurs between the rotating sleeve 22 and the chuck 24. The volute spring 262471 tightens the energy storage. At this time, the rotation speed of the turntable 23 is relatively low, and the centrifugal slider 233 does not contact the bottom of the accommodating groove and does not provide resistance; after the volute spring 262471 is completely rolled up and releases the rotating sleeve 22, the volute spring 262471 drives the rotating sleeve 22 to rotate rapidly, and the turntable 23 drives the permanent magnet 27 to rotate rapidly relative to the winding 25. At this time, the centrifugal slider 233 is subjected to a large centrifugal force, so that the centrifugal slider 233 slides outward under the action of the centrifugal force, and contacts the bottom of the accommodating groove under the cooperation of the first inclined surface and the second inclined surface. The friction between the fourth slider and the bottom wall of the end seat decelerates the turntable 23 to maintain the rotation speed within a preset range, so that the electric energy output by the winding 25 is more stable.

As shown in Figures 4, 5, 7 to 10, the energy-saving emergency light described in this embodiment, in some embodiments, a track block 241 and a friction strip 242 are installed on the side of the chuck 24 facing away from the turntable 23, and a strip hole 243 is opened on the chuck 24 between the track block 241 and the friction strip 242, and a first connecting shaft movably inserted into the strip hole 243 is convexly provided on the outer end of the spiral spring 262471, and a sliding assembly is installed between the track block 241 and the friction strip 242, and the sliding assembly is provided with a second connecting shaft 2612441, an elastic floating connection with a bayonet 247 and a friction block 248 movably provided with the friction cooperation with the friction strip 242, and a track groove is provided on the side of the track block 241 facing the friction strip 242, and the bayonet 247 is movably embedded in the track groove. In this embodiment, a strip hole 243 is provided so that the sliding assembly can be connected to the first connecting shaft of the spiral spring 262471 through the second connecting shaft 2612441, so as to facilitate the winding and unwinding of the spiral spring 262471; a friction block 248, a latch 247 and a track groove are provided so that when the spiral spring 262471 is wound up, the friction block 248 and the friction strip 242 can be used to prevent the user from letting go of the rotating sleeve 22 when the spiral spring 262471 is not completely wound up, and the rotating sleeve 22 is reset under the elastic force of the spiral spring 262471, which is more convenient for the user to operate.

As shown in FIGS. 9 and 10 , the energy-saving emergency light described in this embodiment, in some embodiments, the sliding assembly includes a first slider 244 slidably connected between the track block 241 and the friction strip 242, a second slider 245 slidably mounted on the first slider 244, and a third slider 246 movably mounted at one end of the second slider 245, the second connecting shaft 2612441 is set on the first slider 244, and one end of the second slider 245 is penetrated by a T-shaped second slider 246 along the thickness direction of the second slider 245. The third slider 246 is installed in the second sliding groove, the third slider 246 is provided with a sliding hole, a spring 2471 is provided in the sliding hole, the bayonet 247 is slidably installed in the sliding hole and abuts against the spring 2471, the friction block 248 is provided on the other end of the second slider 245, a spring piece 249 is connected between the friction block 248 and the second slider 245, the second slider 245 is provided with an oblique slot hole 2451, the friction block 248 is provided with a pin shaft 2481, and the pin shaft 2481 is movably embedded in the oblique slot hole 2451. As shown in FIG8 , the energy-saving emergency light described in this embodiment, in some embodiments, the track groove includes a first parallel section 2411 and a second parallel section 2412 extending along the length direction of the track block 241, a first inclined section 2413 is connected between one end of the first parallel section 2411 and one end of the second parallel section 2412, a second inclined section 2414 is connected between the other end of the first parallel section 2411 and the other end of the second parallel section 2412, the depth of the first parallel section 2411 and the depth of the first inclined section 2413 are greater than the depth of the first parallel section 2411, the depth of the first parallel section 2411 and the depth of the first inclined section 2413 are the same, the depth of the second inclined section 2414 is greater than the depth of the second parallel section 2412, and a smooth transition step 2415 is provided between the second inclined section 2414 and the first parallel section 2411; when the spiral spring 262471 is in a natural state, the bayonet 247 extends into the second inclined section 2414 under the elastic force of the spring 2471.

Specifically, when the volute spring 262471 is in a natural state, that is, the volute spring 262471 has no stored energy, the latch 247 extends into the second inclined section 2414 under the elastic force of the spring 2471; when the light-emitting component needs to be powered by a mechanical energy storage component, the user rotates the rotating sleeve 22 clockwise, and relative movement occurs between the rotating sleeve 22 and the chuck 24, so that the volute spring 262471 tightens and stores energy. The volute spring 262471 cooperates with the first connecting shaft and the second connecting shaft 2612441 to drive the first slider 244 to slide inward, and the first slider 244 allows the latch 247 to enter the first parallel section 2411 from the second inclined section 2414 through the smooth transition step 2415. Since the depth of the second inclined section 2414 is greater than the depth of the first parallel section 2411 , the latch 247 compresses the spring 2471 to make an inward movement, and the track block 241 generates a thrust on the second slider 245 through the latch 247, so that the second slider 245 slides relative to the first slider 244, and the friction block 248 moves to contact with the friction strip 242. As the first slider 244 moves, since the movement direction of the friction block 248 is opposite to the direction of the friction force on the friction block 248, the friction block 248, under the action of the friction force on it, makes the pin shaft 2481 overcome the elastic force of the spring sheet 249 and slide outward along the inclined slot hole 2451, so that the resistance between the friction block 248 and the friction strip 242 is reduced, until the force of the spring sheet 249 on the friction block 248 and the friction force of the friction block 248 on the friction strip 242 tend to be balanced, so that the sliding assembly can slide inward along the friction strip 242;

When the user stops rotating the rotating sleeve 22 and the latch 247 is in the first parallel section 2411, the sliding assembly has a tendency to return to the outside under the action of the spiral spring 262471. Due to this tendency, the movement trend direction of the sliding assembly is opposite to the direction when the sliding assembly slides inward. Therefore, under the action of the friction force it receives, the friction block 248 makes the pin shaft 2481 overcome the elastic force of the spring sheet 249 and slide inward along the inclined slot hole 2451, so that the positive pressure between the friction block 248 and the friction strip 242 increases, and then the friction force between the friction block 248 and the friction strip 242 increases, so that the slider assembly is stationary at the current position and cannot be reset under the elastic force of the spiral spring 262471, so as to avoid the rotating sleeve 22 being reset under the elastic force of the spiral spring 262471 after the user lets go during the rotation of the rotating sleeve 22, which is more convenient for the user to perform energy storage operation;

When the vortex spring 262471 is fully rolled up, the latch 247 enters the first inclined section 2413 from the first parallel section 2411. Since the depth of the first inclined section 2413 is greater than the depth of the first parallel section 2411, the spring 2471 causes the latch 247 to extend to cooperate with the first inclined section 2413. At this time, the positive pressure of the track block 241 on the second slider 245 is reduced through the latch 247, so that the friction between the friction block 248 and the friction strip 242 is reduced. As the vortex spring 262471 releases energy, it drives the rotating sleeve 22 to rotate counterclockwise, and the rotating sleeve 22 drives the turntable 23 to rotate. The turntable 23 drives the permanent magnet 27 to move relative to the winding 25. The winding 25 cuts the magnetic flux lines to generate electrical energy to power the lamp body. At the same time, the vortex spring 262471 drives the sliding assembly to slide outward through the first connecting shaft and the second connecting shaft 2612441. The direction of movement is opposite to the direction of the friction force exerted on the friction block 248. Therefore, under the action of the friction force exerted on the friction block 248, the pin shaft 2481 overcomes the elastic force of the spring sheet 249 and slides inward along the inclined slot hole 2451, so that the friction force between the friction block 248 and the friction strip 242 increases relatively, until the force exerted by the spring sheet 249 on the friction block 248 and the friction force exerted on the friction block 248 by the friction strip 242 tend to be balanced, thereby avoiding the spiral spring 262471 from unwinding too fast, making the spiral spring 262471 more stable when unwinding, so as to maintain the rotation speed within a preset range, and making the electrical energy output by the winding 25 more stable; during the unwinding process of the spiral spring 262471, the latch 247 enters the second parallel section 2412 along the first inclined section 2413 until the latch 247 returns to the second inclined section 2414, at which time the unwinding of the spiral spring 262471 is completed.

As shown in FIG9 , in some embodiments of the energy-saving emergency light described in this embodiment, the first slider 244 is provided with a limit bar hole 2442, and the second slider 245 is provided with a limit pin 2452, and the limit pin 2452 is movably embedded in the limit bar hole 2442. In this embodiment, the travel of the second slider 245 is limited by the cooperation between the limit bar hole 2442 and the limit pin 2452; at the same time, the relative movement of the friction block 248 relative to the second slider 245 under the action of friction force is adapted.

In some embodiments of the energy-saving emergency light described in this embodiment, a sealing ring is provided between the inner wall of the rotating sleeve 22 and the inner wall of the energy storage seat 21 to prevent liquid from entering the lampshade 1 through the inner wall of the rotating sleeve 22 and the inner wall of the energy storage seat 21.
