[0024] The emergency lighting controller provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] like Figures 1 to 13As shown in the illustration, this application discloses an emergency lighting controller, which includes a cabinet 100, a front shell module 200, and a rear shell module 300. The front shell module 200 and the rear shell module 300 are detachably connected and electrically connected to each other to facilitate the transmission of electrical signals. Optionally, the cabinet can be a freestanding cabinet for a floor-standing emergency lighting controller, a console cabinet for a console-type emergency lighting controller, or a wall-mounted cabinet for an emergency lighting controller. This application does not impose specific limitations on these aspects.

[0026] The cabinet 100 includes a hinged cabinet body 110 and a cabinet door 120. The cabinet door 120 and the cabinet body 110 enclose a receiving space. A front shell module 200 and a rear shell module 300 are both disposed within this receiving space. The front shell module 200 is detachably connected to the cabinet door 120, and the rear shell module 300 is detachably connected to the cabinet body 110. The front shell module 200 and the rear shell module 300 are opposite each other; or...

[0027] The cabinet 100 includes a cabinet body 110, a front shell module 200 and a rear shell module 300, both of which are disposed in the cabinet body 110. The rear shell module 300 is detachably connected to the cabinet body 110, and the front shell module 200 is detachably connected to the cabinet body 110 through the rear shell module 300. Part of the front shell module 200 is exposed.

[0028] In this embodiment, through modular design, the emergency lighting controller is configured as a cabinet 100, a front shell module 200, and a rear shell module 300. The front shell module 200 and the rear shell module 300 are detachably connected and electrically connected. When the cabinet 100 includes a hinged cabinet body 110 and a cabinet door 120, such as a hinged upright cabinet structure, both the front shell module 200 and the rear shell module 300 are located within the accommodating space enclosed by the cabinet door 120 and the cabinet body 110. Block 200 is detachably connected to cabinet door 120, and rear shell module 300 is detachably connected to cabinet body 110. Front shell module 200 is opposite to rear shell module 300. When cabinet 100 includes cabinet body 110, such as when cabinet 100 is a console-style structure or a non-door upright cabinet structure, both front shell module 200 and rear shell module 300 are located on cabinet body 110. Rear shell module 300 is detachably connected to cabinet body 110, and front shell module 200 is detachably connected to cabinet body 110 through rear shell module 300, with part of front shell module 200 exposed. Therefore, the front shell module 200 and rear shell module 300 disclosed in this application are compatible with the cabinet installation requirements of different cabinets 100, thus applicable to various installation scenarios. Therefore, the embodiments of this application can solve the problem of the relatively limited installation scenarios for current emergency lighting controllers.

[0029] It should be noted that the aforementioned front shell module 200 needs to be waterproofed and dustproofed to prevent water stains, dust and other impurities from the external environment from entering the interior of the front shell module 200 when it is exposed.

[0030] In an optional embodiment, the rear shell module 300 is provided with a receiving cavity, and at least a portion of the front shell module 200 is located within the receiving cavity. The front shell module 200 and the rear shell module 300 are sealed together, thereby preventing water stains, dust, and other impurities from contacting the functional components of the front shell module 200 (such as the antenna 230, USB connector 240, speaker 270, motherboard 320, battery 330, and cable interface board 340, etc., mentioned later) and the functional components of the rear shell module 300 (such as the motherboard 320, battery 330, and cable interface board 340, etc.) through the assembly gap between the front shell module 200 and the rear shell module 300. This serves to protect the functional components of the front shell module 200 and the rear shell module 300 and can meet the IP33 protection level requirements. In addition, when the front shell module 200 and the rear shell module 300 are sealed together and installed in a non-door cabinet 100 (such as a non-door upright cabinet or a console cabinet), this can reduce the protection requirements of the cabinet 100, thereby saving the manufacturing cost of the emergency lighting controller. Of course, the front shell module 200 can also be located outside the receiving cavity of the rear shell module 300. In this case, a seal can be used to seal the connection between the front shell module 200 and the rear shell module 300.

[0031] In a further optional embodiment, the front shell module 200 is provided with an annular mating portion 201, which is located inside the receiving cavity. The annular mating portion 201 fits against the inner wall of the receiving cavity to ensure a sealed fit between the front shell module 200 and the rear shell module 300. The top surface of the annular mating portion 201 is provided with a drainage groove 202. Optionally, the drainage groove 202 is U-shaped and located at the end of the top surface away from the opening of the receiving cavity. Optionally, the drainage groove 202 extends along the width direction of the emergency lighting controller. In this design, the portion of the top surface of the annular mating portion 201 near the opening of the receiving cavity fits against the inner wall of the receiving cavity to prevent water stains, impurities, and other foreign objects from entering. If some foreign objects pass through the assembly gap between the top surface of the annular mating portion 201 and the inner wall of the receiving cavity, they will be collected in the drainage groove 202 for convenient centralized discharge, preventing these impurities from contacting the functional components inside the receiving cavity, thereby protecting the functional components inside the receiving cavity. Of course, the drainage groove 202 may not be provided.

[0032] Optionally, at least one of the bottom surface, the first side surface, and the second side surface of the annular mating part 201 may also be provided with the drain groove 202 to further protect the functional components inside the receiving cavity.

[0033] Optionally, when both the front shell module 200 and the rear shell module 300 are installed in the cabinet 110, the annular mating part 201 of the front shell module 200 and the inner wall of the receiving cavity of the rear shell module 300 can be interference-fitted to improve the sealing performance of the receiving cavity.

[0034] In one optional embodiment, the front housing module 200 includes a front housing 210, a control panel 220, and functional devices. The front housing 210 includes a connected mounting plate 211 and an annular mating portion 201. The annular mating portion 201 is located at the edge of the mounting plate 211. The control panel 220 and the functional devices of the front housing module 200 are all disposed on the mounting plate 211 and are at least partially located within the receiving space formed by the annular mating portion 201, that is, the annular mating portion 201 surrounds each functional device, wherein a portion of an individual functional device extends beyond the receiving space of the annular mating portion 201. The control panel 220 is used for display and convenient touch operation by staff; the antenna 230 is used for transmitting and receiving signals. The antenna 230 can be a WIFI antenna, or other types of antennas, which are not specifically limited here; the USB connector 240 is used to connect external devices and facilitates future software upgrades; the printer 250 is used to print the working information of the emergency lighting controller; the operation buttons 260 are used for manual operation by staff; the speaker 270 is used to transmit sound. Optionally, the speaker 270 can be a buzzer, which has the characteristics of small size and loud volume; the indicator light 280 is used to remind staff.

[0035] Optionally, the front housing module 200 includes a speaker 270. The mounting plate 211 has a sound outlet 211a, with the speaker 270 facing the sound outlet 211a to ensure direct sound transmission, reducing sound loss and improving hearing for staff. Optionally, multiple sound outlets 211a can be used to improve sound transmission efficiency. The control panel 220, operation buttons 260, and indicator lights 280 are all exposed for easy operation and identification by staff.

[0036] Optionally, the USB connector 240 and printer 250 may be exposed; or, in other optional embodiments, the mounting plate 211 is further provided with a first clearance opening 211b, and the functional components of the front shell module 200 also include an antenna 230, a USB connector 240, a printer 250, an operation button 260 and an indicator light 280. The USB connector 240 and printer 250 both face the first clearance opening 211b. The front shell module 200 also includes a first protective cover 290, which is hinged to the mounting plate 211. The first protective cover 290 can cover the first clearance opening 211b to prevent water stains, dust and other impurities in the external environment from entering the front shell 210, thereby protecting the USB connector 240 and printer 250.

[0037] Optionally, the annular mating part 201 includes a top plate 201a, a first side plate 201b, a bottom plate 201c, and a second side plate 201d connected in sequence. The top plate 201a includes a first plate segment 201a1, a second plate segment 201a2, a third plate segment 201a3, and a fourth plate segment 201a4 connected in sequence. The second plate segment 201a2 is bent relative to the first plate segment 201a1, and the third plate segment 201a3 is bent relative to the second plate segment 201a2. The first plate segment 201a1 is folded relative to the third plate segment 201a3. The first plate segment 201a1, the second plate segment 201a2, and the third plate segment 201a3 form the aforementioned drainage groove 202. That is, the drainage groove 202 is directly formed during the manufacturing process of the annular mating part 201, avoiding the need to additionally open the drainage groove 202 on the annular mating part 201. This can save the manufacturing material of the annular mating part 201 and reduce the manufacturing process of the annular mating part 201. Optionally, the fourth plate segment 201a4 is bent relative to the third plate segment 201a3. In the thickness direction of the third plate segment 201a3, the second plate segment 201a2 and the fourth plate segment 201a4 extend in opposite directions. The fourth plate segment 201a4 is connected to the mounting plate 211.

[0038] Optionally, the first side plate 201b, the bottom plate 201c, and the second side plate 201d can all be flat plate structures, thereby reducing the space occupied in the cavity.

[0039] In another optional embodiment, the rear shell module 300 includes a rear shell 310, a motherboard 320, a battery 330, and a cable interface board 340. The motherboard 320, battery 330, and cable interface board 340 can all be collectively referred to as functional components of the rear shell module 300. The cable interface board 340 is used to connect signal transmission lines. The rear shell 310 has a receiving cavity, within which the motherboard 320, battery 330, and cable interface board 340 are all disposed. The battery 330 is electrically connected to the motherboard 320, cable interface board 340, and front shell module 200 via wires, thereby supplying power to them. At least one of the motherboard 320 and cable interface board 340 is signal-connected to the front shell module 200 via a signal line, thereby transmitting signals to facilitate flexible control of the front shell module 200's operation. This solution mounts heavy functional components such as the motherboard 320 and battery 330 onto the cabinet 110, which reduces the weight and volume of the front shell module 200, thereby reducing the load on the cabinet door 120. Furthermore, it avoids interference between the front shell module 200 and the cabinet 110, thus facilitating the opening of the cabinet door 120.

[0040] Optionally, the receiving cavity of the rear shell module 300 can be a continuous whole; or, in other optional embodiments, the rear shell module 300 further includes a partition plate 350, which is disposed within the receiving cavity, dividing the receiving cavity into a first receiving cavity and a second receiving cavity. At least a portion of the front shell module 200 is located within the first receiving cavity, and the motherboard 320, battery 330, and cable interface board 340 are all disposed within the partition plate 350. The motherboard 320, battery 330, and cable interface board 340 are all located within the second receiving cavity. The partition plate 350 is provided with a second clearance opening 351 for avoiding cables and signal lines. This solution separates the functional components of the front shell module 200 and the rear shell module 300 through the partition plate 350. This not only facilitates the arrangement of functional components such as the motherboard 320, battery 330, and cable interface board 340, but also prevents the heat dissipated by the motherboard 320, battery 330, and cable interface board 340 during operation from affecting the front shell module 200.

[0041] In another optional embodiment, the rear shell 310 includes a detachably connected shell 311 and a second protective cover 312. Optionally, the second protective cover 312 and the shell 311 can be connected by fasteners 313 such as screws. The second protective cover 312 is disposed on the side of the shell 311 facing away from the front shell module 200. The second protective cover 312 and the shell 311 are sealed together to prevent water stains, dust and other impurities from the external environment from entering the receiving cavity, thereby further improving the sealing performance of the receiving cavity and enhancing the protection level of the rear shell module 300. Of course, the shell 311 and the second protective cover 312 can also be fixedly connected.

[0042] Optionally, the housing 311 is provided with an annular connecting part 311a at one end near the second protective cover 312. The second protective cover 312 is detachably connected to the annular connecting part 311a by fasteners 313. The annular connecting part 311a is provided with a water collection tank 311a1 for collecting impurities (such as water stains, dust, etc.). The opening of the water collection tank 311a1 faces the side wall of the second protective cover 312. The impurities collected in the water collection tank 311a1 can be discharged in a concentrated manner to avoid entering the receiving cavity.

[0043] Optionally, the water collection trough 311a1 is U-shaped, and the annular connecting portion 311a includes a fifth plate segment 311a2, a sixth plate segment 311a3, and a seventh plate segment 311a4 connected in sequence. The fifth plate segment 311a2 is bent relative to the sixth plate segment 311a3, and the sixth plate segment 311a3 is bent relative to the seventh plate segment 311a4. The fifth plate segment 311a2 and the seventh plate segment 311a4 are opposite to each other to form the aforementioned water collection trough 311a1. The seventh plate segment 311a4 fits against the cover of the second protective cover 312 to further increase the sealing of the receiving cavity. Optionally, the second protective cover 312 is detachably connected to the seventh plate segment of the annular connecting portion 311a by fasteners 313.

[0044] Optionally, the rear shell module 300 and the cabinet 110 can be detachably connected by screws or the like; or, in another optional embodiment, the rear shell module 300 further includes a hook-on component 360. Hook-on components 360 are detachably provided at both opposite ends of the rear shell 310 in the width direction of the emergency lighting controller.
