Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Example:

[0032] Please see Figures 1 to 6 This invention provides an emergency power supply device for downlights, including an emergency power supply box 1, a connecting structure 2, and a power supply component 3. The connecting structure 2 is installed at the bottom of the emergency power supply box 1 and is used to fix the lamp on the emergency power supply box 1. The power supply component 3 is used to supply power to the lamp.

[0033] The emergency power supply box 1 has a receiving cavity, and the connecting structure 2 includes two opposing clamping components 21, which are elastically connected to the outside of the emergency power supply box 1. The power supply component 3 is fixed inside the receiving cavity. When the two clamping components 21 are in a state of mutual or reverse springback, they clamp and fix the lamp. By using two clamping components 21 to clamp and fix the lamp to the emergency power supply, compared with the screw installation method in related technologies, manual screw-driving is not required, the assembly steps are simple and the time consumption is short. At the same time, the two clamping components 21 of the connecting structure 2 can automatically clamp, which can realize the semi-automatic assembly of the lamp and downlight emergency power supply device, which is convenient and quick.

[0034] Please see Figure 3 and Figure 6 In one embodiment, the connection structure 2 further includes a connection box 22 fixed to the emergency power box 1 and having a limiting cavity. The clamping assembly 21 includes a slide rod 211 with one end slidably fitted into the limiting cavity and the other end extending out of the limiting cavity, and a clamping member 212 fixed to the slide rod 211 and located outside the limiting cavity. The slide rod 211 is elastically connected to the connection box 22. The clamping members 212 of the two clamping assemblies 21 are distributed at opposite ends of the connection box 22. When the two clamping members 212 are in a state of mutual or opposite springback, the two clamping members 212 clamp and fix the lamp.

[0035] It should be understood that, since one end of the slide rod 211 is slidably fitted into the limiting cavity and the other end extends out of the limiting cavity, the slide rod 211 is elastically connected to the connecting box 22, and the clamping member 212 is fixed to the slide rod 211 and located outside the limiting cavity, the clamping member 212 is elastically connected to the connecting box 22 through the slide rod 211. This allows the two clamping members 212 to clamp and fix different types and specifications of hanging lamps, eliminating the need to produce emergency power boxes 1 with different sizes of mounting holes, thereby reducing production costs. At the same time, during the process of fixing the lamps to the emergency power box 1 by the connecting structure 2, screws are not required, that is, no manual screw-driving is required, making the installation and fixing method simple.

[0036] It should be noted that when the two clamping members 212 are in the opposite spring-back state, they clamp the light fixture inward; when they are in the opposite spring-back state, they clamp the light fixture outward. The end of the clamping member 212 away from the slide bar 211 protrudes from the contact side surface of the connecting box 22, which allows the clamping member 212 and the light fixture to have sufficient contact area, ensuring the friction between them and preventing the light fixture from falling off during clamping; it also facilitates the clamping member 212 applying force to the light fixture.

[0037] Please see Figure 1 , Figure 2 and Figure 3In one embodiment, the clamping assembly 21 further includes a blocking portion 213 protruding outward from the outside of the slide rod 211, and an elastic member 214 sleeved on the outside of the slide rod 211 and located within the limiting cavity. The blocking portion 213 is located within the limiting cavity, and one end of the elastic member 214 abuts against the end of the blocking portion 213 near the clamping member 212, while the other end abuts against the cavity wall of the limiting cavity, to provide a rebound force for the clamping member 212 to rebound towards the limiting cavity. Specifically, the blocking portion 213 may be annular, and the end of the blocking portion 213 at the end of the slide rod 211, i.e., the side of the blocking portion 213 away from the clamping member 212, can abut against the cavity wall of the limiting cavity. The elastic member 214 may be a spring. In the initial state, the blocking part 213 abuts against the cavity wall of the limiting cavity, and the clamping member 212 abuts against the outside of the connecting box 22, and the elastic member 214 does not undergo elastic deformation. In the clamping state, the sliding rod 211 slides outward to drive the blocking part 213 to move. The elastic member 214 undergoes elastic deformation under the joint compression of the blocking part 213 and the cavity wall of the limiting cavity. Under the interaction of forces, the clamping member 212 is subjected to the rebound force provided by the elastic member 214, so that the two clamping members 212 can clamp and fix the lamp.

[0038] During the specific clamping process, one clamping member 212 is moved until the space between the two clamping members 212 is adapted to the lamp. The lamp is placed in the space between the two clamping members 212 and the clamping member 212 is released. At this time, the two clamping members 212 will interact with each other until they are in equilibrium. The elastic member 214 undergoes elastic deformation under the joint compression of the blocking part 213 and the wall of the limiting cavity, and generates a rebound force that rebounds towards the limiting cavity, so that the two clamping members 212 are in a state of rebounding towards each other, thereby enabling the two clamping members 212 to clamp and fix the lamp. Specifically, the two clamping members 212 clamp and fix the lamp inward.

[0039] Please see Figure 4 , Figure 5 and Figure 6In one embodiment, the clamping assembly 21 further includes a blocking portion 213 protruding outward from the outer side of the slide rod 211, and an elastic member 214 sleeved on the outer side of the slide rod 211 and located within the limiting cavity. The blocking portion 213 is located at one end of the slide rod 211 that extends into the limiting cavity. One end of the elastic member 214 abuts against the end of the blocking portion 213 near the clamping member 212, and the other end abuts against the cavity wall of the limiting cavity, so as to provide a rebound force for the clamping member 212 to rebound in the direction close to the limiting cavity. Specifically, the blocking portion 213 may be annular, located between the two ends of the slide rod 211, and the side of the blocking portion 213 near the clamping member 212 can abut against the cavity wall of the limiting cavity. The elastic member 214 may be a spring. In the initial state, the blocking part 213 abuts against the cavity wall of the limiting cavity, and the clamping member 212 is spaced apart from the outer side of the connecting box 22, and the elastic member 214 does not produce elastic deformation. In the clamping state, the slide rod 211 slides inward to drive the blocking part 213 to move. The elastic member 214 produces elastic deformation under the joint compression of the blocking part 213 and the cavity wall of the limiting cavity. Under the interaction of forces, the clamping member 212 is subjected to the rebound force provided by the elastic member 214, so that the two clamping members 212 can clamp and fix the lamp.

[0040] During the specific clamping process, one clamping member 212 is pressed until the space between the two clamping members 212 is adapted to the lamp. The lamp is placed in the space between the two clamping members 212 and the clamping member 212 is released. At this time, the two clamping members 212 will interact with each other until they are in equilibrium. The elastic member 214 undergoes elastic deformation under the joint compression of the blocking part 213 and the wall of the limiting cavity, and generates a rebound force that rebounds away from the limiting cavity, so that the two clamping members 212 are in the opposite rebound state, thereby enabling the two clamping members 212 to clamp and fix the lamp. Specifically, the two clamping members 212 clamp and fix the lamp outward.

[0041] Please see Figure 2 and Figure 5In one embodiment, the outer side of the emergency power box 1 is provided with a mounting groove 11 adapted to the connecting box 22. The connecting box 22 is fastened and fixed in the mounting groove 11, and two clamping members 212 are respectively located at opposite ends of the connecting box 22. The mounting groove 11 can be a rectangular groove. Since the connecting box 22 is fastened and fixed in the mounting groove 11, screws are not required, thus reducing the complexity of materials and assembly processes. The two clamping members 212 are respectively located at opposite ends of the connecting box 22, which facilitates the connection structure 2 in fixing the lamp to the emergency power box 1. Preferably, the side wall of the box body 221 opposite to the clamping members 212 is provided with a clearance hole 223. The sliding rod 211 passes through the clearance hole 223 and extends out of the limiting cavity. The outer diameters of the blocking part 213 and the elastic member 214 are both larger than the outer diameter of the clearance hole 223, so that the blocking part 213 and the elastic member 214 cannot disengage from the limiting cavity, ensuring that the elastic member 214 is squeezed by the blocking part 213 and the cavity wall of the limiting cavity.

[0042] Please see Figure 2 and Figure 5 In one embodiment, the cover plate 222 is provided with a third fastening structure 6, which is used to fasten with a fourth fastening structure provided with the emergency power box 1. Specifically, the third fastening structure 6 consists of multiple fastening members fixed to the cover plate 222, each fastening member surrounding the box body 221. The fourth fastening structure provided with the emergency power box 1 is a fastening groove. When the fastening member is fastened into the corresponding fastening groove, the connecting box 22 is fixed to the emergency power box 1. Preferably, four fastening members can be provided. The four corner areas of the box body 221 are provided with fitting grooves, and the four fastening members are located in the four fitting grooves. When the fastening member is fastened into the fastening groove, the cover plate 222 is fixedly connected to the emergency power box 1, and the box body 221 is pressed and fixed to the emergency power box 1 by the cover plate 222. According to actual needs, the third fastening structure 6 can be a fastening groove provided on the cover plate 222, and the fourth fastening structure can be a fastening member fixed on the emergency power box 1.

[0043] Please see Figure 3 and Figure 6In one embodiment, the connecting box 22 further includes a plurality of partitions 224 fixed within the limiting cavity and spaced apart. The partitions 224 divide the limiting cavity into a plurality of independently configured limiting sub-cavities. Each clamping component 21 is provided with a plurality of slide rods 211, and the plurality of limiting sub-cavities are configured one-to-one with the plurality of slide rods 211. Specifically, the partitions 224 are fixed to the bottom of the box body 221. There are three partitions 224 in total, and the three partitions 224 divide the limiting cavity into four independently configured limiting sub-cavities. Each clamping component 21 is provided with two slide rods 211, and each slide rod 211 is connected to an elastic member 214, so that the two elastic members 214 provide a rebound force to the clamping member 212, thereby increasing the rebound force of the clamping member 212 and thus increasing the clamping force of the two clamping members 212 to clamp the lamp. Preferably, a slide rod 211 of another clamping assembly 21 is provided between two adjacent slide rods 211 of the same clamping assembly 21, that is, the two slide rods 211 connected to the same clamping member 212 have a certain gap, which is beneficial to ensure that the clamping member 212 is subjected to balanced force.

[0044] Please see Figure 2 and Figure 4 In one embodiment, the clamping member 212 is provided with a threaded hole, and the clamping assembly 21 further includes an adjusting member 9 threaded into the threaded hole. The moving direction of the adjusting member 9 is parallel to the sliding direction of the slide rod 211. Specifically, the adjusting member 9 can be a stud. By adjusting the length of the adjusting member 9 extending out of the clamping member 212, the clamping tightness of the two clamping members 212 clamping the lamp can be changed. Depending on actual needs, the clamping member 212 can be a flat plate. A soft rubber block can be provided on the side of the clamping member 212 near the connecting box 22. The soft rubber block can contact the lamp to prevent the lamp from being damaged due to compression.

[0045] Please see Figure 3 and Figure 6 In one embodiment, the emergency power box 1 includes a housing 12 with a receiving cavity, a base 13 fixed to the housing 12 and covering the receiving cavity, and a partition 14 fixed at both ends to the base 13 and the housing 12 respectively and located in the receiving cavity. The partition 14 divides the receiving cavity into two independently set receiving sub-cavities. One of the two receiving sub-cavities is equipped with a power supply component 3 to form a power supply cavity, and the other forms a wiring cavity, so that the wiring cavity and the power supply cavity are set independently, that is, the emergency power box 1 has an independent wiring area and a power supply area.

[0046] Please see Figure 1 and Figure 4In one embodiment, the housing 12 has a window 15 on its periphery, which exposes the wiring cavity. The downlight emergency power supply device also includes a flip plate 4 rotatably connected to one side of the window 15, which is used to close or open the window 15.

The two wire holes 16 on the housing 12 connect to the wiring cavity and the power supply cavity, respectively, and the two wire holes 16 on the base 13 also connect to the wiring cavity and the power supply cavity, respectively. Specifically, the housing 12 can be cylindrical. Both the two wire holes 16 on the housing 12 and the wire holes 16 on the base 13 are fitted with disposable protective plates. These protective plates can protect the receiving cavity before wiring and can be removed directly during wiring. It should be understood that because the housing 12 has a window 15 exposing the wiring cavity on its periphery, the lighting fixture will not interfere with the wiring when wiring is performed on the wiring board 10, making the wiring operation convenient and quick. Cables can be introduced and exited from the top and bottom of the housing 12, simplifying the wiring method. Preferably, the two wire holes 16 on the base 13 are distributed on both sides of the connection between the two clamping components 21, so that the introduction and exit of the cable will not interfere with the clamping component 212 clamping the lamp.

[0047] Please see Figure 2 and Figure 5 In one embodiment, the side wall of the housing 12 near the base 13 is provided with a first fastening structure, and the outer side of the base 13 is provided with a second fastening structure 5.

There are two connecting shafts, and the line connecting the two connecting shafts is parallel to the length direction of the corresponding side wall of the window 15, so that the flip plate 4 is rotatably connected to the side wall of the window 15, thereby allowing the window 15 to be opened or closed by rotating it on the outer casing.

[0049] Please see Figure 1 and Figure 4In one embodiment, the emergency power supply box 1 further includes a first connecting structure 7 disposed on the flip plate 4 and a second connecting structure 8 disposed on the outer shell. When the first connecting structure 7 and the second connecting structure 8 are connected, the flip plate 4 covers the wiring cavity; when the first connecting structure 7 and the second connecting structure 8 are separated, the flip plate 4 opens the wiring cavity. Specifically, the first connecting structure 7 includes a hook fixed to the free side of the flip plate 4, and the second connecting structure 8 includes a retaining plate disposed on the outer shell, the hook being able to snap onto the retaining plate. Depending on actual needs, the first connecting structure 7 and the second connecting structure 8 can be fixed by magnetic attraction, that is, both the first connecting structure 7 and the second connecting structure 8 can be magnetic components.

[0050] Please see Figure 1 Preferably, the hook includes a main body fixed to the flip plate 4 and two corner hooks fixed to the main body and spaced apart. When the hook is snapped into the plate, the two corner hooks are located at opposite ends of the plate so that the hook can be snapped into the plate and fixed.
