Description

Technical Field

[0001] This disclosure relates to the field of lighting technology, and more particularly to a multifunctional handheld lighting lamp. Background Technology

[0002] Handheld lights, due to their lightweight, long battery life, and portability, have become indispensable tools in emergency rescue and outdoor adventure activities. Traditional focused designs suffer from narrow fields of view, failing to meet the needs of wide-angle illumination in dim outdoor environments. Furthermore, in dim or dark outdoor environments, traditional handheld lights (such as flashlights and emergency lights) are generally difficult to locate after use. Current solutions largely rely on passive marking such as reflective strips and fluorescent coatings, but these measures are completely ineffective in the absence of ambient light.

[0003] Furthermore, existing handheld lights cannot be easily adjusted in position. Adjusting the angle of the handheld light by wrist can easily cause fatigue and injury over time. When lighting is needed for outdoor activities, situations often arise where both hands are busy and an additional support is needed to fix the flashlight. For example, when lighting is needed inside a tent, it is difficult to find a suitable support structure for the flashlight, or the beam angle cannot be adjusted after it is fixed, thus causing inconvenience. Summary of the Invention

[0004] In view of the above, this disclosure provides a multifunctional handheld lighting lamp including: a body assembly, a lamp head assembly and a handle assembly mounted on the body assembly. The lamp head assembly is movably mounted on the body assembly by a rotating structure. The rotating structure includes a lamp head shaft, a locking shaft, a shaft pressure plate, a limiting arm and a limiting arm compression spring. Both ends of the lamp head shaft are inserted into the body assembly. A first through hole is provided in the middle of both the lamp head assembly and the lamp head shaft. The locking shaft passes through the first through hole and is installed perpendicularly to the lamp head shaft, thus movably connecting the lamp head assembly and the rotating structure. The limiting arm compression spring is mounted on the limiting arm, and the limiting arm is mounted on the shaft pressure plate. The shaft pressure plate is fixedly mounted on the body assembly. The shaft pressure plate and the body assembly cooperate to insert the lamp head shaft into the body assembly.

[0005] In some embodiments, the lamp head assembly has a maximum angle of 195° when flipped upward from its initial state; a maximum angle of 90° when rotated clockwise; and a maximum angle of 235° when rotated counterclockwise. The lamp head assembly includes five lighting modes.

The lamp head rear cover and the lamp head front cover are fastened together with screws. The floodlight aluminum substrate is installed in the first concave surface of the aluminum substrate locking nut, which contacts the lamp head rear window, fixing the lamp head rear window in the third through hole of the lamp head rear cover. The second end face of the aluminum substrate locking nut contacts the first surface of the main light source aluminum substrate. One end of the reflector contacts the second surface of the main light source aluminum substrate, and the other end of the reflector is located in the concave surface of the lamp head front window. The second end face of the lamp head front window is fixed in the third through hole of the lamp head front cover.

[0007] In some embodiments, the lamp head assembly further includes a smoke scanner, with a raised fourth through hole in the center of the aluminum substrate locking nut, the raised fourth through hole being inserted between the reflectors, the smoke scanner being located in the raised fourth through hole, and the laser emitting end of the smoke scanner facing the front window of the lamp head.

[0008] In some embodiments, the body assembly includes: an upper body shell and a lower body shell, the upper body shell including two transverse portions and an inclined portion connected between the two transverse portions, the pivot plate including a transverse portion and an inclined portion, the transverse portion of the pivot plate cooperating with the first transverse portion of the upper body shell to form an insertion hole for mounting the lamp holder pivot.

[0009] The inclined portion of the pivot plate and the inclined portion of the upper shell form a first enclosed space. The space outside the first enclosed space and the first part of the lower shell form a space to accommodate the lamp head assembly. The second horizontal portion of the upper shell and the second part of the lower shell are fastened together to form a second enclosed space. The battery plate fixes the battery to the inner wall of the second horizontal portion of the upper shell. The main control board bracket fixes the main control board to the inner wall of the second horizontal portion of the upper shell. The battery is closer to the inclined portion.

[0010] In some embodiments, a communication chip is installed on the main control board (PCBA), the communication chip includes a positioning module, and an antenna chip is installed on the inner sidewall of the second lateral portion of the body shell near the communication chip, the antenna chip being electrically connected to the main control board.

[0011] In some embodiments, a first magnet and a second magnet are also included. The first magnet is located directly below the battery pressure plate and is installed on the second part of the lower housing of the device. The battery pressure plate does not contact the first magnet. A cover plate is installed on the first part of the lower housing of the device, and the second magnet is installed below the cover plate and fixed on the first part of the lower housing of the device.

[0012] In some embodiments, an access nut is also provided on the second part of the lower housing.

[0013] In some embodiments, the handle assembly is movably mounted on the body assembly, the handle assembly can rotate upwards by a maximum angle of 40 degrees, one end of the handle assembly is movably mounted on the body assembly by a handle torsion spring and a screw, the other end of the handle assembly is snapped onto the body assembly, and the body assembly is provided with a slot that engages with the snap.

[0014] In some embodiments, multiple warning lights and a display screen are also installed below the card slot on the main casing, with the display screen being further away from the card slot than the multiple warning lights.

(Reference) Figure 1 and Figure 3-5 In this embodiment, the multi-functional handheld lighting lamp includes: a body assembly 23, a lamp head assembly 1 and a handle assembly 55 mounted on the body assembly 23. The lamp head assembly is movably mounted on the body assembly 23 by a rotating structure 7. The rotating structure 7 includes a lamp head shaft 7, a locking shaft 2, a shaft pressure plate 32, a limiting arm 25 and a limiting arm compression spring 26. The two ends of the lamp head shaft 7 are inserted into the body assembly 23. A first through hole is provided in the middle of the lamp head assembly 1 and the lamp head shaft 7. The locking shaft 2 passes through the first through hole and is installed perpendicularly to the lamp head shaft 7, thus movably connecting the lamp head assembly 1 and the rotating structure 7. The limiting arm compression spring 26 is mounted on the limiting arm 25. The limiting arm 25 is mounted on the shaft pressure plate 32. The shaft pressure plate 32 is fixedly mounted on the body assembly 23. The shaft pressure plate 32 and the body assembly 23 cooperate to insert the lamp head shaft 7 into the body assembly 23.

[0031] In the embodiments of this application, such as Figure 3 As shown, an O-ring seal 16 is fitted on one end of the locking shaft 2, and the other end of the locking shaft 2 is threaded, and is movably connected to the lamp holder shaft 7 through a nut 17, a disc spring 18, and a flat washer 19. For aesthetic purposes, as well as for dust and water protection and to extend the service life of the lighting lamp, a lamp holder decorative cover 6 is also provided on the nut 17.

[0032] refer to Figure 2a When the lamp head assembly flips upwards from its initial state, the maximum angle is 195°. The initial state of the lamp head assembly refers to the state where the lamp head assembly is folded completely into the body assembly, such as... Figure 1 As shown. In the initial state, the angle θ between the lamp head assembly and the vertical direction ranges from 15° to 20°, for example, it can be 15°, 16°, 16.5°, 18°, 20°, etc. The lamp head assembly can be completely folded into the body assembly without occupying extra space, which facilitates transportation and protection of the lamp head assembly, while also expanding the illumination angle range in the vertical direction.

[0033] refer to Figures 2b-2c The lamp head assembly has a maximum rotation angle of 90° when rotated clockwise and 235° when rotated counterclockwise. The lamp head assembly consists of two sides, A and B. When folded, side A faces outward and side B faces inward, enabling double-sided illumination and effectively meeting the needs of wide-range lighting from different angles. This light supports multi-angle adjustment to adapt to various usage requirements, demonstrating high flexibility.

[0034] In some embodiments, such as Figure 3As shown, the lamp head assembly 1 includes: a lamp head rear cover 4, a lamp head rear viewing window 11, a floodlight aluminum substrate 13, an aluminum substrate locking nut 3, a main light source aluminum substrate 12, a reflector 9, a lamp head front viewing window 8, a lamp head sealing ring 10, and a lamp head front cover 5. Both the lamp head front cover 5 and the lamp head rear cover 4 have a second through hole (not labeled in the figure) through which the locking shaft 2 passes. Both the lamp head rear cover 4 and the lamp head front cover 5 have a third through hole in their middle sections. The lamp head rear cover 4 and the lamp head front cover 5 are fastened together with screws. The aluminum substrate locking nut... The floodlight aluminum substrate 13 is installed within the first concave surface of the mother lamp 3. This first concave surface contacts the rear window 11 of the lamp head, fixing the rear window 11 within the third through hole of the lamp head rear cover 4. The second end face of the aluminum substrate locking nut 3 contacts the first surface of the main light source aluminum substrate 14. One end of the reflector cup 9 contacts the second surface of the main light source aluminum substrate 12, and the other end of the reflector cup 9 is located within the concave surface of the front window 8 of the lamp head. The second end face of the front window 8 is fixed within the third through hole of the lamp head front cover 5. The floodlight aluminum substrate 13 is fixed to the aluminum substrate locking nut 3 by screws, and the aluminum substrate locking nut 3 is fixed to the lamp head rear cover 4 by screws. The main light source aluminum substrate 12 is fixed to the lamp head rear cover 4 by screws 21, and the reflector cup 9 is also fixed to the main light source aluminum substrate 12 by screws. The lamp head assembly supports bi-directional lighting; side A can produce focused light, and side B can produce floodlight, offering a wide range of applications. In this embodiment, both the rear cover 4 and the front cover 5 of the lamp head can be made of aluminum alloy. The front viewing window 8 and the rear viewing window 11 of the lamp head can both be made of explosion-proof glass, such as tempered glass. LED beads are positioned at the three vertices of an equilateral triangle on the main light source aluminum substrate 12, and three corresponding reflectors 9 are also positioned at the three vertices of an equilateral triangle, with the three reflectors not touching each other. This arrangement not only concentrates the light in the center of the lamp head, but also provides a total of 360° illumination, evenly illuminating all directions. Furthermore, the non-contacting vertices result in a larger light source area in the center of the spotlight, allowing for a wider illumination range. In some examples, a hole for the smoke scanner 14 can be positioned in the center of the three reflectors. The main light source aluminum substrate 12 uses triangular high-brightness LED beads to achieve a wide coverage effect of strong light.

[0035] In some embodiments, such as Figure 3 As shown, the lamp head assembly 1 may also include a smoke scanner 14. The aluminum substrate locking nut 3 has a raised fourth through hole in the middle. After assembly, the raised fourth through hole is inserted between the reflectors 9. The smoke scanner 14 is located in the raised fourth through hole, and the laser emitting end of the smoke scanner 14 faces the front window 8 of the lamp head. The main light source aluminum substrate 12 also has a fifth through hole through which the smoke scanner 14 passes in the middle. The aluminum substrate locking nut 3 also has a wiring through hole near the edge.

[0036] In this embodiment, the smoke scanner 14 may include at least: a terminal block, a laser emitter, a metal sleeve, and a protective cover. The laser emitter emits a point laser of a specific wavelength. One end of the terminal block is electrically connected to one end of the laser emitter, and the other end of the terminal block is connected to one end of a lead wire, the other end of which has a power input plug. One end of the metal sleeve is fitted onto the other end of the laser emitter, and the other end of the metal sleeve is movably connected to and embedded within the protective cover. Adjusting the protective cover changes the length of the metal sleeve embedded within it. A lens group is located at the end of the protective cover furthest from the metal sleeve. The lens group converts the point laser into a line laser, which forms stripes on the surface of the object. The lens group includes a convex lens, a linear lens, and a lens fixing member. The lens fixing member is fitted over the convex lens, fixed to the inner wall of the protective cover, and fixes the linear lens within the protective cover. The convex lens is closer to the metal sleeve than the linear lens. The smoke scanner 14 also includes a spring, which is located within the metal sleeve. One end of the spring contacts the laser emitter, and the other end contacts the lens group. The point laser emitted by the laser emitter has a wavelength range of 400nm-500nm. The smoke scanner 14 is used to scan the surface of objects with uneven smoke concentration distribution and forms striped laser lines on the surface. The shape, spacing, and phase of these striped laser lines change with the geometry and height of the object (e.g., smoke) surface, creating a clear view of smoke flow, quickly defining contours, and locating holes and objects in space, allowing rescuers to quickly understand the current situation. The smoke scanner 14 helps rescuers quickly identify terrain, observe smoke trends, avoid entering deep into the fire, and improve rescue efficiency and safety.

[0037] In this embodiment, the lamp head assembly includes five lighting modes. These five modes can be a high-intensity light mode, a low-intensity light mode, a strobe mode, a floodlight mode, and a smoke scanning mode (also known as a laser mode). Side A of the lamp head assembly 1 is controlled by the main light source aluminum substrate 12 to form a focused beam, including three operating modes: high-intensity light mode, low-intensity light mode, and strobe mode. Side B of the lamp head assembly 1 is controlled by the floodlight aluminum substrate 13 to form a floodlight mode. Side A of the lamp head assembly 1 can also be controlled by a smoke scanner 14 to form a laser mode. The focused beam provides long-distance illumination, while the floodlight provides large-area illumination. The light emitted from both sides is uniform and soft, providing different lighting modes for different work environments.

[0038] Combination Figure 1 and Figure 5The multifunctional lighting lamp in this embodiment of the application also includes a switch button 50, which is installed on the body assembly 23, located between the handle assembly 55 and the rotating structure 7, close to the rotating structure 7. The switch button 50 adopts a large button switch structure design, which is easy to identify and operate. In some embodiments, the setting rules of the switch button 50 and the five lighting modes can be as follows: (1) Pressing the switch button once turns on the strong light mode, pressing it twice turns on the weak light mode, pressing it three times turns on the strobe mode, pressing it four times turns on the floodlight mode, and pressing it five times turns off the lighting lamp, and so on.

[0039] (2) In any mode, press and hold the switch button for 3 seconds to turn on the laser mode, and press the switch button again to turn off the laser mode, and repeat this cycle. When the laser mode is on, other light modes are off.

[0040] like Figure 5 and Figure 6 As shown, the body assembly may include: an upper housing 31 and a lower housing 30. The upper housing 31 includes two horizontal sections 311 and 312 and an inclined section 313 connecting the two horizontal sections. The pivot plate 32 includes a horizontal section 321 and an inclined section 322. The horizontal section 321 of the pivot plate 32 cooperates with the first horizontal section 311 of the upper housing 31 to form an insertion hole for mounting the lamp head pivot 7. The inclined section 322 of the pivot plate 32 and the inclined section 3313 of the upper housing 31 form a first enclosed space. The space outside the first enclosed space and the first section 301 of the lower housing 30 form a space for accommodating the lamp head assembly 1. In the embodiments of this application, as... Figure 5 As shown, a rotating structure 7 and a switch button 50 are installed in the first enclosed space.

[0041] Combined Figure 2c The second transverse portion 312 of the upper casing 31 and the second portion 302 of the lower casing 30 are fastened together to form a second enclosed space. The battery clamping plate 37 fixes the battery 33 to the inner wall of the second transverse portion 312 of the upper casing 31, and the main control board bracket 35 fixes the main control board 34 to the inner wall of the second transverse portion 312 of the upper casing 31. The battery 33 is closer to the inclined portion 313 than the main control board 34. The battery 33, battery clamping plate 37, main control board 34, and main control board bracket 35 are all located within the second sealed space. Figure 5As shown, the battery 33 is located in the middle of the body assembly 23 of the lighting fixture, and the main control board 34 is vertically mounted at the rear of the body assembly 23. The battery clamping plate 37 is fixed to the upper shell 31 by screws. In this embodiment, both the upper shell 31 and the lower shell 30 are injection molded from polycarbonate (PC) bulletproof rubber material, which has the characteristics of being drop-resistant, impact-resistant, and resistant to acid and alkali corrosion. This allows the lighting fixture to maintain a stable working state in harsh environments such as humidity, dust, oil, and outdoor rain and snow, providing reliable lighting support for rescue work. The battery 33 can be a multi-cell lithium-manganese dioxide battery (e.g., a four-cell 21700 type).

[0042] In some embodiments, the main control board 34 can also be used to detect the battery level and activate a low-voltage alarm when the battery voltage is lower than a certain percentage of the rated voltage (e.g., 20% of the rated voltage). If the battery level is insufficient, the handheld light will not be able to start next time.

[0043] In some embodiments, a communication chip (not shown) is mounted on the main control board 34. The communication chip includes a positioning module. An antenna chip 36 is mounted on the inner wall of the second lateral portion 312 of the upper casing 31 near the communication chip. The antenna chip 36 is electrically connected to the main control board 34. A charging interface 38 (e.g., a Type-C interface) is also mounted on the inner wall of the second lateral portion 312 of the upper casing 31 opposite to the antenna chip 36. This charging interface 38 is used to charge the battery and is fixed between the main control board bracket 35 and the inner wall of the upper casing by a wedge block. The charging interface 38 and the antenna chip 36 are distributed on the inner walls of both sides of the second lateral portion 312 of the upper casing 31.

[0044] In this application, the communication chip is used to transmit the location information of the lighting fixture to the mobile terminal and to receive warning messages, modification messages, and control messages sent by the mobile terminal. The communication chip can be a 4G / 5G communication chip. Each lighting fixture also includes device information and device operation status information. The device information may include user information such as user name and organization, and device number. The device number can be a unique code of the communication chip. The location information may include latitude and longitude information. The device operation status information may include: the lighting fixture's power information, current lighting mode, remaining usage time, and signal status, etc. When transmitting location information to the mobile terminal, the device information and device operation status information are also transmitted to the mobile terminal simultaneously.

[0045] The mobile terminal can be an application installed on a computer or mobile phone. In case of an emergency, the mobile terminal can send an alarm message to the lighting fixture. The alarm message can include audible and visual alarms, along with text warnings or call messages. Call messages can include individual or group call prompts, or a forced alarm prompt. The audible and visual alarm can be a red and blue warning light flashing at a certain frequency (e.g., 8-10Hz). Text warning messages can include phrases like "Danger at the scene, please evacuate to a safe area as soon as possible," and call messages can be forced alarm prompts, such as continuously displaying "Forced Alarm" on the screen. Modification information can include modified device information and power-on information, and control information can include controlling changes to light brightness, light mode, or deactivating the alarm.

[0046] In some embodiments, when the light receives a text warning message from the mobile device, double-clicking the switch button clears the warning message, indicating that the light has received and read the warning message. Afterwards, both the mobile device and the light return to their initial states. If the mobile device does not clear the warning message, the text on the display screen will remain displayed, and the mobile device will continue to indicate that the light is in an unread state. During use, if the warning message is not cleared, or if the light is forcibly shut down, the battery is depleted, or a circuit malfunction occurs, the mobile device will indicate that the light is faulty.

[0047] When the mobile app triggers a forced alarm for one or more lights, the power button cannot deactivate it; it can only be deactivated via the mobile app. To deactivate the light, it must be forcibly shut down. After a forced shutdown, the mobile app simultaneously deactivates the forced alarm for that light and restores it to its initial state. During a forced alarm, if the light suddenly experiences the following issues: battery depletion, circuit failure, etc., the mobile app will display that the light is faulty. It should be noted that at any setting, double-clicking the power button displays user information on the screen. The user information is displayed for 10 seconds before returning to its original state. The light mode remains on during this operation.

[0048] In some embodiments, the lower housing 30 also includes a first magnet and a second magnet (neither shown in the figures). The first magnet is located directly below the battery plate 37 and is mounted on the second portion 302 of the lower housing 30 by a first magnet protective cover 41 and screws. The battery plate 37 does not contact the first magnet. A cover plate 40 is mounted on the first portion 301 of the lower housing 30, and the second magnet is mounted below the cover plate 40 and fixed to the first portion 301 of the lower housing by a second magnet protective cover and screws. The multiple magnets on the lower housing allow the lighting lamp to adhere to ferrous surfaces, such as car hoods or roofs, or the walls of tin shacks, facilitating use during outdoor activities or rescue operations.

[0049] refer to Figure 7On the outer surface of the second part 302 of the lower housing 30, a connecting nut 51 is also provided. This connecting nut 51 can be an M8 threaded hole. The connecting nut 51 allows the lighting lamp to be mounted on a support tripod for fixing or raising the lamp. For example, in dike patrol and survey lighting, the lighting lamp can be mounted on a support rod, which is then fixed to the dike to provide illumination and warning. (Continue to refer to...) Figure 7 A magnetic charging base 52 is also provided on the outer surface of the second part 302 of the lower casing 30, located directly below the battery 33 and not overlapping with the first magnet. This dual charging system enhances the versatility of the lighting fixture.

[0050] Combination Figure 5 and Figure 8 The handle assembly 55 is movably mounted on the body assembly 23. The handle assembly 55 can rotate upwards to a maximum angle of 40 degrees. One end of the handle assembly 55 (near the inclined part of the upper shell) is movably mounted on the body assembly 23 using a handle torsion spring and screws. The other end of the handle assembly 55 (near the tail end of the second horizontal part of the upper shell) is secured to the body assembly 23 by a latch 56. The body assembly 23 is provided with a latch groove 63 that mates with the latch (e.g., Figure 2c (As shown). Pressing one end of the buckle releases it from the slot, allowing the handle assembly to rotate upwards. The handle assembly 55 is shaped like an inverted "7". A handle release hook 57 is located in the middle of the handle assembly 55. The top of the handle release hook 57 is movably mounted on the handle assembly 55 by a release torsion spring 59, a knurled pin 60, and a pair of locking screws 61 and 62. The tail end of the handle release hook 57 can be fastened into a slot 63 in the handle assembly 55. Pressing the top of the handle release hook 57 forms a clamp between the handle release hook 57 and the handle assembly 55, allowing the light to be clamped to various surfaces, such as tents. Handle pads 58 are installed in the slot 63 and on the handle assembly 55 (the tail end of the handle release hook 57). The handle assembly 55 also has a hook for attaching a shoulder strap, allowing the light to be carried on the shoulder.

[0051] In some embodiments, multiple warning lights (not shown) and a display screen are also installed below the slot 63 on the upper casing 31. The display screen is further away from the slot 63 than the multiple warning lights. The display screen is mounted on the inner wall of the main control board 34 by a display screen bracket and a display screen adapter plate, and the display screen protrudes outside the upper casing 31. Multiple warning lights are installed on one side of the main control board 34. The multiple warning lights can be four high-brightness red and blue warning lights. When the spotlight is turned on at any level, the rear red and blue warning lights turn on simultaneously. The frequency of the red and blue warning lights can be red flashing twice, blue flashing twice, red and blue flashing twice simultaneously, and so on. When the spotlight is turned off, the red and blue warning lights turn off simultaneously. The red and blue warning lights have a strong visual effect in the dark and are more suitable for special environment search and rescue scenarios such as mountain search and rescue, maritime search and rescue, and dike patrol and survey.

[0052] It is readily understood that the display screen is used to display the aforementioned location information and warning messages, device information, and device operating status information sent by the mobile device. The display screen may include an OLED display screen with backlighting, which can be clearly displayed even in dark environments. In some embodiments, the display screen may also be made of explosion-proof glass, such as tempered glass. Taking floodlight mode as an example, the display screen may display a location icon and latitude and longitude information, light mode, battery level, and remaining usage time in floodlight mode.
