Description

Technical Field

[0001] The present application relates to the field of power tools, and more particularly to a lighting device. Background Art

[0002] A standing lamp in the related art is a lighting device that can stand on the ground. Standing lamps are widely used in various fields due to their advantages such as a wide lighting range, convenient movement, and portability. The lamp body of the lighting lamp is supported by a support frame. Most of the existing support frames are tripods. The tripod includes three support legs. One end of the support leg is rotatably connected to the rod body of the support frame, and the other end can support the ground. The support leg switches between the storage position and the support position by rotation. In order to form a larger range of support, support legs with a larger length need to be designed, which increases the size and weight of the lamp body.

[0040] Before explaining any embodiment of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0041] In the present application, the terms "comprise", "include", "have" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0042] In the present application, the term "and / or" is a relationship description of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present application generally represents an "and / or" relationship between the associated objects before and after.

[0043] In this application, the terms "connect", "combine", "couple", and "mount" can be direct connections, combinations, couplings, or mounts, or they can be indirect connections, combinations, couplings, or mounts. Among them, by way of example, a direct connection means that two parts or components are connected together without an intermediate member being provided therebetween, and an indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and can include electrical connections or couplings.

[0044] In this application, those of ordinary skill in the art will understand that relative terms used in conjunction with a quantity or condition (e.g., "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of the two endpoints. Relative terms may refer to a plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not employ relative terms should also be disclosed as specific values having tolerances. In addition, "substantially" when expressing a relative angular positional relationship (e.g., substantially parallel, substantially perpendicular) may refer to a plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0045] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0046] In this application, the directional terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive direction, but can also be understood as the side direction. For example, below can include directly below, lower left, lower right, front lower, and rear lower, etc.

[0047] In this application, the terms "controller", "processor", "central processing unit", "CPU", and "MCU" are interchangeable. When using the units "controller", "processor", "central processing unit", "CPU", or "MCU" to perform specific functions, unless otherwise specified, these functions can be performed by a single one of the above units or multiple of the above units.

[0048] In this application, the terms "device", "module", or "unit" can be implemented in the form of hardware or software in order to achieve specific functions.

[0049] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operations and processes of a computer system or a similar electronic computing device (e.g., controller, processor, etc.).

[0050] To clearly illustrate the technical solution of this application, the upper side, lower side, left side, right side, front side, and rear side are also defined as Figure 1 follows.

[0051] This application provides a lighting device 10 for illuminating a working area. The lighting device 10 is a portable bracket lamp that is convenient to carry. Specifically, the lighting device 10 is a standing lamp. When a user needs to work outdoors, the user can carry the lighting device 10 to any outdoor location to provide lighting needs. The lighting device 10 is different from a table lamp, which usually needs to be placed on a table for illumination. However, the lighting device 10 provided in this application is a standing lamp that can stand on the ground and illuminate any working area with lighting needs. The lighting device 10 is different from a floor lamp used at home. The floor lamp used at home or indoors does not have a handling scenario, and the floor lamp used at home or indoors does not need to resist the influence of general outdoor wind or outdoor environment when in use. There are differences in the requirements for use safety and portability compared with the lighting device 10 of this application.

[0052] As Figures 1 to 5As shown, the lighting device 10 includes a lamp head assembly 100, a support rod assembly 200, and a bracket assembly 300. The lamp head assembly 100 includes at least one lighting lamp 101. After the lighting lamp 101 is turned on, it can change the user's visual environment, enabling the user to work better. The support rod assembly 200 is configured to support the lamp head assembly 100. In some embodiments, the lamp head assembly 100 is disposed at the upper end of the support rod assembly 200. The bracket assembly 300 is configured to support the support rod assembly 200, and at least a part of the bracket assembly 300 is disposed at the lower end of the support rod assembly 200. The bracket assembly 300 includes a connecting portion 310, a push rod portion 320, and a leg portion 330. The leg portion 330 supports on the placement surface, the connecting portion 310 is connected to the support rod assembly 200, and the leg portion 330 is driven by the push rod portion 320. Among them, the bracket assembly 300 includes an unfolded state in which the push rod portion 320 drives the leg portion 330 to move away from the connecting portion 310. In the unfolded state, both ends of the leg portion 330 in the extending direction are respectively away from the connecting portion 310. Exemplarily, the leg portion 330 includes a first end 330a and a second end 330b along the extending direction. In this embodiment, the leg portion 330 extends in the up and down direction, the first end 330a is the upper end of the leg portion, and the second end 330b is the lower end of the leg portion. Exemplarily, the second end 330b is the end of the leg portion 330 that contacts the ground or the placement surface.

[0053] The leg portion 330 is driven by the push rod portion 320 to translate, that is, the first end 330a and the second end 330b are respectively away from the connecting portion 310, so that the bracket assembly 300 switches to the unfolded state in which the leg portion 330 moves away from the connecting portion 310. The distances that the first end 330a and the second end 330b move away from the connecting portion 310 can be the same or different.

[0054] The leg portion 330 is not directly connected to the connecting portion 310. The leg portion 330 and the connecting portion 310 are indirectly connected through the push rod portion 320, and the leg portion 330 and the connecting portion 310 are not rotationally connected. Exemplarily, the first end 330a of the leg portion 330 is not rotationally connected to the connecting portion 310. The second end 330b of the leg portion 330 is not rotationally connected to the connecting portion 310.

[0055] Compared with the existing standing lamp that uses a tripod as a support, when operating the tripod so that the standing lamp can stand on the ground, one end of the leg forming the tripod is hinged to the column of the standing lamp. By rotating the leg, only the bottom end moves away from the column of the standing lamp, resulting in a relatively small support range of the tripod. If a larger support area is required, according to the Pythagorean theorem, the maximum radius of the support area is the length of the tripod leg. At this time, the tripod leg is almost completely laid flat on the support surface, and the stability of placing the lighting device is affected when the ground is uneven with potholes or bumps. Therefore, the tripod leg needs to be set very long to ensure the support stability. The bracket assembly 300 of the lighting device 10 provided in this application is provided with a push rod part 320 between the connecting part 310 and the leg part 330. Under the push of the push rod part 320, both ends (the first end 330a and the second end 330b) of the leg part 330 in its extending direction can move away from the connecting part 310 respectively. In this embodiment, by setting the push rod part 320 to move the leg part 330 as a whole away from the support rod assembly 200, the size of the support area formed by the standing lamp on the placement plane is no longer limited by the length of the leg part 330. The leg part 330 can be moved to a position farther from the support rod assembly 200 or the lamp head assembly 100. Without increasing or decreasing the length of the leg part 330, the support area of the leg part 330 is increased, and the stability of the entire lighting device 10 is improved. In some embodiments, in the unfolded state, the length of the leg part 330 is less than the maximum distance between the leg part 330 and the center line of the support rod assembly 200. In this embodiment, the compactness of the structure of the lighting device is ensured, the portability of the product is improved, and at the same time, the probability of the lighting device 10 tipping over is reduced, making the lighting device 10 more stable when working under harsh working conditions.

[0056] In some embodiments, the push rod part 320 includes two connecting rods that are rotatably connected. The two connecting rods are connected by a rotating shaft, and at least one end of the two connecting rods can move relative to the leg part 330 or the support rod assembly 200. By applying force to the connecting rods, the two connecting rods rotate around the rotating shaft. The two connecting rods have two sets of oppositely arranged ends, and the distance between each set of corresponding ends of the two connecting rods rotating around the rotating shaft can be increased, so that the leg part 330 moves away from the connecting part 310.

[0057] Such as Figure 3As shown, optionally, the push rod portion 320 includes two link rods rotatably connected in an X shape. The two link rods are respectively a first link rod 321 and a second link rod 322. One end of the first link rod 321 is rotatably connected relative to the connecting portion 310. The other end of the first link rod 321 is rotatably connected relative to the leg portion 330. One end of the second link rod 322 is rotatably connected to and connected to the support rod assembly 200 relative to the connecting portion 310. The other end of the second link rod 322 is rotatably connected relative to the leg portion 330. The included angle between the first link rod 321 and the second link rod 322 can change, and at the same time, the dimension in the direction perpendicular to the support rod assembly 200 changes. Exemplarily, the first link rod 321 can be displaced in the axial direction of the support rod assembly 200, and the second link rod 322 is displaced in the axial direction of the leg portion 330. In some other embodiments, both the first link rod 321 and the second link rod 322 can be displaced in the axial direction of the support rod assembly 200 and in the axial direction of the leg portion 330. As long as the X-shaped connection of the first link rod 321 and the second link rod 322 can form a radial telescopic movement.

[0058] Continue to refer to Figure 3 and Figure 5 As shown, the leg portion 330 includes a leg main body 331 and a connecting ring sleeve 333. The leg main body 331 is a tubular structure extending in the vertical direction. To make the X-shaped connection of the first link rod 321 and the second link rod 322 form a radial telescopic movement, the leg main body 331 is configured as a telescopic structure. The leg main body 331 includes a first tube 3311 and a second tube 3312 sleeved thereon. A leg sleeve 3313 connects the first tube 3311 and the second tube 3312, and the first tube 3311 and the second tube 3312 can slide relative to each other to adjust the leg main body 331 to an appropriate position, so that the leg main body 331 is maintained at a target length.

[0059] In some embodiments, the connecting ring sleeve 333 is fixedly arranged on the leg main body 331. Optionally, two connecting ring sleeves 333 are arranged on each leg main body 331, and the connecting ring sleeves 333 are respectively connected to the outer ends of the first tube 3311 and the second tube 3312. The first link rod 321 and the second link rod 322 are respectively connected to the first tube 3311 and the second tube 3312 through the connecting ring sleeves 333. The first link rod 321 and the second link rod 322 are respectively rotatably connected to the connecting ring sleeves 333. When the included angle between the first link rod 321 and the second link rod 322 can change, the first tube 3311 and the second tube 3312 move relative to each other.

[0060] In some alternative embodiments, the connecting collar 333 is slidably sleeved on the leg body 331. Optionally, two connecting collars 333 are slidably arranged on each leg body 331. When the included angle between the first connecting rod 321 and the second connecting rod 322 can change, the connecting collar 333 slides on the leg body along with the change of the above-mentioned included angle. The first connecting rod 321 and the second connecting rod 322 are respectively connected to the first tube 3311 and the second tube 3312 through the connecting collar 333.

[0061] In some alternative embodiments, two connecting collars 333 are arranged on each leg body 331. One of the connecting collars 333 is fixedly connected, and one connecting collar 333 is slidably sleeved on the leg body 331. The length of the leg body 331 can cover the length when the connecting collar 333 moves to the farthest end.

[0062] Of course, in other alternative embodiments, the leg body 331 may include more telescopic tubes, so that the leg body 331 has a larger telescopic range.

[0063] In addition, it should be noted that the push rod portion 320 can also include more rotatably connected connecting rods. The multiple connecting rods are rotatably connected to form a net structure. By pushing and pulling, the distance between the two opposite sides of the push rod portion 320 is increased or decreased, so as to achieve the purpose of moving the leg portion 330 away from the connecting portion 310.

[0064] In addition to including two rotatably connected connecting rods, in some other embodiments, the push rod portion 320 includes at least two parallel connecting rods, and the connecting rods connect the leg portion 330 and the connecting portion 310. By integrally rotating the two parallel connecting rods, the leg portion 330 is moved away from the connecting portion 310.

[0065] Exemplarily, as Figure 6a shown, the push rod portion 320 includes two parallel connecting rods 321b. One end of each connecting rod is rotatably connected to the leg portion 330, and the other end of each connecting rod is rotatably connected to the connecting portion 310. By rotating the two connecting rods, the included angle between the connecting rod and the connecting portion 310, and the included angle between the leg portion 330 and the connecting rod both change. When the connecting rod is perpendicular to the connecting portion 310, the leg portion 330 is farthest from the connecting portion 310. It should be noted that the lengths of the two parallel connecting rods can be the same or different. When the lengths of the two connecting rods are the same, when the connecting rod is perpendicular to the support rod assembly 200, the leg portion 330 can support the ground vertically; when the lengths of the two connecting rods are different, when the connecting rod is perpendicular to the support rod assembly 200, the leg portion 330 can support the ground obliquely. In addition, the number of connecting rods included in the push rod portion 320 can also be increased according to requirements, such as three, four, etc., so that the leg portion 330 is more stable.

[0066] As shown Figure 6b in FIG. Figure 6b , the push rod portion 320 includes two parallel link rods. One end of each link rod is rotatably connected to the leg portion 330, and the other end of each link rod is rotatably connected to the connecting portion 310. Among them, each link rod includes a first link rod 321c and a second link rod 322c that are hinged. The first link rod 321c is connected to the connecting portion 310, and the second link rod 322c is connected to the leg portion 330. When the leg portion 330 approaches the connecting portion 310, the first link rod 321c and the second link rod 322c approach each other, and the angle between the first link rod 321c and the second link rod 322c gradually decreases. It can be understood that the first link rod 321c and the second link rod 322c fold. When the leg portion 330 moves away from the connecting portion 310, the first link rod 321c and the second link rod 322c unfold, and the angle between the first link rod 321c and the second link rod 322c approaches 180°.

[0067] In addition to the above two structures for the leg portion 330, as Figure 6c shown in FIG. Figure 6c , in some other embodiments, the push rod portion 320 includes a hydraulic push rod or an electric push rod 312d. The structures of the hydraulic push rod and the electric push rod are both prior arts and will not be elaborated here.

[0068] In addition to including the unfolded state as Figure 2 and Figure 3 shown in FIG. Figure 2 and FIG. Figure 3 , as Figure 1 and Figure 4 shown in FIG. Figure 1 and FIG. Figure 4 , the support assembly 300 further includes: a storage state in which the leg portion 330 moves in a direction approaching the connecting portion 310. In the storage state, at least one end of the leg portion 330 in its extending direction approaches each other around the support rod assembly 200. In this embodiment, at least one end of the leg portion 330 in its extending direction approaches the connecting portion 310. In this embodiment, the first end 330a and the second end 330b of the leg portion 330 respectively approach the connecting portion 310. When the support assembly 300 is in the storage state, the structural dimensions of the lower part of the lighting device 10 are significantly reduced, making the lighting device 10 easier to store and transport. It should be noted that the power for the leg portion 330 to switch to the storage state can come from manual driving by the user or from the retraction driving of the push rod portion 320.

[0069] The number of the leg portion 330 and the push rod portion 320 can be one or more. When the number of the leg portion 330 is multiple, the multiple leg portions 330 are arranged at intervals in the circumferential direction around the support rod assembly 200. The arrangement of the multiple leg portions 330 makes the structural stability of the support assembly 300 higher. In one embodiment, as Figure 2As shown, the bracket assembly 300 includes three leg portions 330 and three push rod portions 320. The three push rod portions 320 and the three leg portions 330 are connected in a one-to-one correspondence, and the three push rod portions 320 are simultaneously connected to a connecting portion 310. When in the storage state, the first ends 330a of the three leg portions 330 approach each other to the outer periphery of the connecting portion 310. The second ends 330b of the three leg portions 330 approach each other to the outer periphery of the connecting portion 310.

[0070] To enable the multiple push rod portions 320 to simultaneously push the corresponding leg portions 330, continue to refer to Figure 3 As shown, the connecting portion 310 includes a movable collar 311. The movable collar 311 is movably sleeved on the central tube 201 of the support rod assembly 200, and the push rod portion 320 is hinged to the movable collar 311. The end of the movable connecting rod is rotatably connected to the movable collar 311. The leg portion 330 and the movable collar 311 are indirectly connected through the push rod portion 320, and the leg portion 330 and the movable collar 311 are non-rotatably connected. By axially driving the movable collar 311 to move relative to the support rod assembly 200, the connecting rod of the push rod portion 320 can rotate relative to the movable collar 311, so that the connecting rods 322 and 321 can rotate around their rotation axes, thereby changing the shape of the push rod portion 320 and pushing the leg portion 330 to move. In this embodiment, when the bracket assembly 300 is in the storage state, the movable collar 311 moves to the first position, and when the bracket assembly 300 is in the deployed state, the movable collar 311 moves to the second position. In the direction of the axis 20A of the central tube, the first position is above the second position.

[0071] Continue to refer to Figure 3As shown, the connecting portion 310 further includes a second collar 312. The second collar 312 and the movable collar 311 are both sleeved on the central tube 201, and the second collar 312 is disposed below the movable collar 311. The end of the connecting rod of the push rod portion 320 is rotatably connected to the second collar 312. In this embodiment, when the bracket assembly 300 is switched from the deployed state to the retracted state, the movable collar 311 moves from the second position to the first position, and the leg portion 330 moves in a direction approaching the connecting portion 310. During the process of the movable collar 311 moving from the second position to the first position, the second collar 312 undergoes an upward displacement along the axial direction of the central tube, so that the leg portion will not collide with or rub against the ground. Exemplarily, the axial movement distance of the second collar 312 is less than the axial movement distance of the movable collar 311. In this embodiment, the axial movement distance of the second collar 312 is less than or equal to 60 mm. When the second collar 312 undergoes displacement, the movable collar 311 synchronously undergoes axial displacement, but when the movable collar 311 undergoes axial displacement, it does not necessarily accompany the displacement movement of the second collar 312. In this embodiment, a collar limiting portion 3121 is provided on the central tube 201, configured to limit the axial displacement of the second collar 312. Optionally, the collar limiting portion 3121 is formed or connected to the central tube 201, and the collar limiting portion 312 includes a radial protrusion, a limiting bolt connected to the central tube, or other limiting structures radially protruding from the central tube 201. In order to enable the leg portion 330 to maintain its position in the retracted state, thereby preventing the leg portion 330 from accidentally spreading during the transportation of the lighting device 10, the lighting device 10 further includes a locking assembly, which is configured to at least hold the leg portion 330 in the position of the retracted state.

[0072] In this embodiment, the lighting device holds the leg portion 330 in the position of the retracted state by locking the movable collar 311. For ease of operation, the lighting device further includes a movable handle portion 500 that forms a receiving space and a gripping portion. The movable handle portion 500 is formed or connected to the connecting portion 310. The movable handle portion 500 is formed or connected to the movable collar 311, and the movable handle portion 500 moves along the axis 20A direction of the central tube 201 with the movable collar 311.

[0073] In some embodiments, the locking assembly is disposed in the receiving space of the movable handle portion 500. The locking assembly includes a limiting portion and a locking portion that cooperates with the limiting portion. One of the limiting portion and the locking portion is disposed on the central tube 201, and the other is disposed on the movable collar 311. As Figure 5As shown, the limiting part is a locking hole, the locking part is a locking pin 800, one of the locking hole and the locking pin 800 is arranged on the central tube 201, and the other is arranged on the movable collar 311 or the movable handle 500, and the locking pin 800 is plugged and matched with the locking hole. Of course, in addition to the combination of the locking hole and the locking pin 800, other structures can also be adopted, such as a combination of a hook and a snap ring.

[0074] Further, in some embodiments, the limiting portion includes a first limiting portion 801 corresponding to a position for keeping the leg portion 330 in the storage state and a second limiting portion 802 for keeping the leg portion 330 in the expanded state. In a specific embodiment, the first limiting portion 801 is an upper locking hole provided on the central tube 201, and the second limiting portion 802 is provided on a lower locking hole provided on the central tube 201. The locking latch 800 is plugged and matched with the first limiting portion 801 so that the bracket assembly 300 is maintained in the storage state, and the locking latch 800 is matched with the second limiting portion 802 so that the bracket assembly 300 is maintained in the maximum expanded state.

[0075] In addition, in some embodiments, the lighting device 10 further includes an unlocking structure, the unlocking structure including a trigger 510 and a driving member 400, the trigger 510 being movably connected to the gripping portion of the mobile handle portion 500 so that the trigger moves relative to the housing of the mobile handle portion 500. The trigger 510 is connected to the locking latch 800 so that when the trigger 510 is pressed, the locking latch 800 is disengaged from the limiting portion. Exemplarily, when in the storage state, the trigger 510 is pressed so that the locking state between the locking latch 800 and the first limiting portion 801 is released. At this time, the driving member 400 drives the moving collar 311 to move. In this embodiment, the driving member 400 is an elastic member, such as a spring. When the bracket assembly 300 switches from the deployed state to the stored state, the elastic member stores energy, and when the bracket assembly 300 is maintained in the stored state, the elastic member is always in the energy storage state. After the trigger 510 is triggered, the elastic member releases elastic potential energy to drive the movable ring 311 to move, and the leg portion 330 moves in a direction away from the connecting portion 310, so that the bracket assembly 300 switches from the storage state to the deployment state.

[0076] Optionally, the trigger 510 is biased (e.g., has a biasing member, such as a spring). Optionally, the locking latch 800 is biased (e.g., has a biasing member, such as a spring) so that when the user releases the trigger 510, the locking latch 800 is biased toward the limit portion. The biasing member releases the biasing force to move the locking latch 800 into the limit portion. Due to the effect of the biasing force, the locking latch 800 is kept in the limit portion.

[0077] In this embodiment, the lamp head assembly 100 is arranged at the top of the support rod assembly 200, and the number of the lighting lamps 101 can be set to one or more according to requirements.

[0078] When the lighting lamps 101 are configured to be multiple, the multiple lighting lamps 101 are evenly distributed around the circumferential direction of the support rod assembly 200. In one embodiment, the number of the lighting lamps 101 is configured to be three. The three lighting lamps 101 are evenly distributed around the circumferential direction of the support rod assembly 200. Of course, in other embodiments, the number of the lighting lamps 101 can also be set to other numbers according to requirements, such as 2, 4 or more.

[0079] In some alternative embodiments, the lighting lamps 101 can be installed on the support rod assembly 200 by a detachable connection manner, so that the user can adjust the lamp head assembly 100 to be a single lamp head or a multi-lamp head according to requirements. The detachable connection manners include but are not limited to magnetic attraction, connection by a connecting member, snap connection, etc.

[0080] In some embodiments, the structures of the multiple lighting lamps 101 are the same. As Figure 2 shown, the lighting lamp 101 has surface light sources with equal sizes, and the surface light sources can be circular light sources, square light sources, etc. Of course, in some other embodiments, the structures of the multiple lighting lamps 101 can also be different. For example, it includes a main lamp and an auxiliary lamp. The auxiliary lamp is arranged on the side of the main lamp. According to the user's requirements, the auxiliary lamp can be selected to be turned on or off. The main lamp and the auxiliary lamp can be unfolded into a plane, so as to increase the light source area.

[0081] To facilitate the installation of the lighting lamp 101, continue to refer to Figure 2 shown. The lamp head assembly 100 further includes a lamp socket 102. The lamp socket 102 is sleeved and fixed on the support rod assembly 200, and the lighting lamp 101 is connected to the lamp socket 102. In this embodiment, the multiple lighting lamps 101 are evenly arranged around the circumferential direction on the lamp socket 102. To facilitate the storage of the lamp head assembly 100, one end of the lighting lamp 101 is rotatably connected to the lamp socket 102, so that the lighting lamp 101 can be retracted to the Figure 1 shown folded state, and can also be unfolded to the Figure 2 shown vertical lighting state. Of course, the lighting lamp 101 can also be rotated to a horizontal lighting state in which it is horizontal, that is, the lamp body of the lighting lamp 101 directly irradiates the ground. For the single-lamp lamp head assembly 100, the lighting lamp 101 can also be rotatably connected to the lamp socket 102. The maximum rotation angle of the lighting lamp 101 can reach 360°, so as to meet the lighting requirements at various angles.

[0082] The lighting lamp 101 is rotatably connected to the lamp base 102, which not only improves the storage performance of the lamp head assembly 100, but also can adjust the light angle by rotating the lighting lamp 101, making the use of the lighting lamp 101 more flexible and better meeting the needs of users. The specific way of the rotatable connection of the lighting lamp 101 is that a rotating shaft is provided at one end of the lighting lamp 101, and a rotating shaft hole is provided on the lamp base 102, and the rotating shaft is rotatably connected in the rotating shaft hole. In some embodiments, three pairs of rotating shaft holes are provided in the circumferential direction of the lamp base 102, and the rotating shafts of the three lighting lamps 101 are respectively connected to the three pairs of rotating shaft holes. The rotations of the three lighting lamps 101 are independent of each other, and different lighting lamps 101 can be adjusted to different lighting angles according to needs.

[0083] The support rod assembly 200 includes a rod in a tubular structure, and the rod can be a round tube, a square tube, a special-shaped tube, etc. In some embodiments, the rod is a non-retractable straight rod structure. In this embodiment, the rod is a retractable telescopic rod. Optionally, as Figure 2 shown, the rod includes a central tube 201 and at least one extension tube 202. The bottom end of the central tube 201 is fixedly connected to the bracket assembly 300. Among them, the extension tube 202 connected to the central tube 201 is sleeved inside or outside the central tube 201 and can axially slide relative to the central tube 201, so that the extended length of the rod changes. The other extension tubes 202 are sequentially sleeved and slid. By pulling out the extension tube 202, the rod can be Figure 1 switched from the folded state shown in Figure 2 to the extended state shown in Figure 2 or by pushing the extension tube 202, the rod is switched from the extended state shown in Figure 1 to the folded state shown in

[0084] A locking member 203 is provided between the central tube 201 and the extension tube 202 to keep the central tube 201 and the extension tube 202 at the required length. The locking member 203 prevents the central tube 201 and the extension tube 202 from moving relative to each other by one or several ways such as slot matching, shaft hole matching or extrusion. Exemplarily, the locking member 203 includes an operating member for the user to operate, and the user fixes the central tube 201 and the extension tube 202 by operating the operating member. Figure 1 In this way, the support rod assembly 200 is easy to store, carry and transfer. In this embodiment, when the rod is in the folded state shown in Figure 2 and Figure 3As shown, the support rod assembly 200 further includes a base 203, which is fixedly connected to the bottom end of the central tube 201 and has a relatively large support area, so that the lighting device 10 in the retracted state can stand on the ground relying only on the support of the base 203. In some embodiments, when the bracket assembly 300 is in the deployed state, the base 203 does not contact the ground. That is to say, when the bracket assembly 300 is in the deployed state, the lighting device 10 stands and is supported only by the leg portions 330. In some embodiments, when the bracket assembly 300 is in the retracted state, the base 203 contacts the ground. That is to say, when the bracket assembly 300 is in the retracted state, the lighting device 10 stands and is supported only by the base 203. In some embodiments, when the bracket assembly 300 is in the retracted state, the base 203 contacts the ground. That is to say, when the bracket assembly 300 is in the retracted state, the lighting device 10 stands and is supported by the base 203 and the support legs 330 surrounding the outer periphery of the converging center rod.

[0085] In some embodiments, multiple rods of the support rod assembly 200 are limited by a two-way damper. The two-way damper rod expands and contracts under the action of the gravity of the lighting lamp 101. In this embodiment, the two-way damper assembly includes a damping rubber ring provided. The relative movement of the telescopic rod is restricted by the frictional force provided by the damping rubber ring. Using a two-way damper instead of a locking member with an operating member is convenient for users to operate on the one hand and enables stepless adjustment of the length of the support rod assembly on the other hand, so that the user only needs to pull the rod to a suitable position to keep the rod in the required position.

[0086] Continue to refer to Figure 1 As shown, in some embodiments, the lighting device 10 further includes a battery pack 600, which is disposed on the support rod assembly 200 and above the bracket assembly 300. The battery pack 600 is configured to supply power to the lighting lamp 101, thus facilitating use. Therefore, this lighting device 10 is different from the existing lamps that can only be powered by alternating current. This lighting device 10 can also be called a DC lighting device. The use of the portable battery pack 600 can realize DC power supply to the lighting lamp 101, so that the lighting device 10 does not need to be externally connected to the mains power, improving the mobility and convenience of use of the lighting device 10, and making the lighting device 10 more suitable for outdoor working areas. Of course, it can be understood that this lighting device 10 is not limited to only using the battery pack 600 for power supply. If this lighting device 10 can be powered by the battery pack 600 or by alternating current, this lighting device 10 can also be called a DC lighting device.

[0087] It can be understood that the battery pack 600 can be a lithium battery pack, a solid-state battery pack or a soft-pack battery pack. In this embodiment, the nominal voltage of the battery pack 600 is approximately equal to 10V and less than or equal to 100V. In some embodiments, the nominal voltage of the battery pack 600 is 10.8V, 24V, 36V, 48V, 56V or 80V. It should be explained that the nominal voltage usually refers to the voltage specified by the manufacturer or seller on the labels, packages, user manuals, instructions, advertisements, marketing or other supporting documents of these products. Alternatively, the nominal voltage of the battery pack 600 can also be obtained by detection or calculation.

[0088] In some embodiments, the battery pack 600 is disposed on the support rod assembly 200 and above the bracket assembly 300; in some embodiments, the battery pack 600 is disposed on the bracket assembly 300.

[0089] To stably fix the battery pack 600 on the support rod assembly 200, continue to refer to Figure 3 As shown, the lighting device 10 further includes a battery mounting portion 701. The battery mounting portion 701 includes a mounting shell fixed on the central tube 201. An insertion and extraction cavity is formed on the mounting shell. The battery pack 600 can enter and exit the mounting shell by insertion and extraction, and a conductive member for conducting the battery pack 600 and the lighting lamp 101 is formed inside the mounting shell. The mounting shell has the function of protecting the battery pack 600. The cooperation between the mounting shell and the central tube 201 enables the battery pack 600 to be stably fixed on the support rod assembly 200.

[0090] Continue to refer to Figure 3 As shown, in some embodiments, the lighting device 10 further includes a handle portion 700 configured to grip the lighting device 10. The handle portion 700 is disposed on the support rod assembly 200. In some embodiments, the handle portion 700 forms or is connected to a battery mounting portion 701 configured to mount the battery pack 600.

[0091] In some embodiments, the handle portion 700 is integrated with the mounting shell; in a specific embodiment, the handle portion 700 is a U-shaped structure, making it easier for the user to hold the handle portion 700 and making the handling of the lighting device 10 more convenient and labor-saving.

[0092] In some embodiments, the handle portion 700 forms or is connected to a disc portion 710. The disc portion is disposed above the battery pack 600. The disc portion 710 is disposed around the central tube 201. When the lighting lamp 101 rotates to the folded state completely overlapping with the central tube 201 (such as Figure 1As shown in the figure, when observed from the up-and-down direction, the orthographic projection of the lamp head assembly 100 is located inside the orthographic projection of the disc portion 710. In some embodiments, the disc portion 710 includes a switch box, or a part of the structure is configured as a switch box, and electronic components for controlling the working state of the lamp head assembly 100 are provided inside the switch box. Optionally, the disc portion 710 further includes a switch 720 for controlling the lighting or turning off of the lamp head assembly 100. Optionally, the disc portion 710 further includes a mode adjustment for controlling the lighting state of the lamp head assembly 100, including but not limited to brightness, color temperature, color, and timing.

[0093] As Figures 7 - 10 shown, the lighting device 10B in another embodiment of the present application, the difference between this lighting device and the lighting device 10 as Figures 3 to 5 described lies in different locking components and different unlocking structures. The following description mainly focuses on the differences between the lighting device 10B and the lighting device 10.

[0094] In this embodiment, the locking component and the unlocking structure of the lighting device 10B are provided on the fixed handle 700B. In this embodiment, the fixed handle 700B forms a receiving space and a holding portion 730B. The locking component is provided in the receiving space of the fixed handle portion 700B.

[0095] As Figure 8b and Figure 9 shown, the lighting device 10B holds the leg portion 330 in the retracted state position by locking the movable collar 311. In this embodiment, the locking component includes: a first linkage plate 810B formed or connected to the connecting portion, a limiting portion, and a locking portion 800B that cooperates with the limiting portion. Among them, the locking portion 800B is at least partially provided inside the fixed handle portion 700B and partially protrudes from the fixed handle portion 700B. The limiting portion includes a first limiting portion 801B that holds the leg portion 330 in the retracted state. Exemplarily, the first limiting portion 801B is provided on the first linkage plate 810B, the first linkage plate 810B is formed or connected to the movable collar 311, and the first linkage plate 810B extends along the axis 20A direction of the central tube. The first linkage plate 810B moves along the axis 20A direction of the central tube with the movable collar 311. When the bracket assembly 300 is in the retracted state, the movable collar 311 moves to the first position, and the first limiting portion 801B on the first linkage plate 810B moves to a position corresponding to the locking portion 800B, and the locking portion 800B enters the first limiting portion 801B to form a locked state, so as to hold the movable collar 311 in the first position, and further hold the leg portion 330 in the retracted state position.

[0096] As Figure 7 and Figure 8a and Figure 10As shown, the limiting part further includes a second limiting part 802 for holding the supporting leg 330 in the deployed position. In this embodiment, the second limiting part 802 is provided on the first linkage plate 810B. The first linkage plate 810B moves along the axis 20A of the central tube with the moving collar 311. When the bracket assembly 300 is in the deployed state, the moving collar 311 moves to the second position, and the second limiting part 802B on the first linkage plate 810B moves to a position corresponding to the locking part 800B, and the locking part 800B enters the second limiting part 802B to form a locked state, so as to hold the moving collar 311 in the second position, and further hold the supporting leg 330 in the deployed state.

[0097] Optionally, the first limiting part 801B is an upper locking hole provided on the first linkage plate 810B, and the second limiting part 802B is a lower locking hole provided on the first linkage plate 810B. The locking part 800B is a locking pin. The locking part 800B is inserted and matched with the first limiting part 801B so that the supporting leg 330 is maintained in the retracted position, and the locking part 800B is matched with the second limiting part 802B so that the supporting leg 330 is maintained in the maximum deployed position.

[0098] In this embodiment, the unlocking structure is provided on the fixed handle part 700B and partially outside the fixed handle part 700B to facilitate user operation. The unlocking structure is configured to release the locked state between the limiting part and the locking part 800B. In this embodiment, the unlocking structure includes a trigger 740B provided on the fixed handle part 700B. The trigger 740B is movably connected to the holding part 730B so that the trigger 740B moves relative to the housing of the fixed handle part 700B.

[0099] To ensure both the strength of the structure and the comfort of user operation. In this embodiment, the trigger 740B is provided at the upper end 731B of the holding part 730B of the fixed handle part 700B, while the locking part 800B is provided at the lower end 732B of the fixed handle part 700B. The locking part 800B is closer to the connecting part so that the length of the first linkage plate 810B is appropriate. At the same time, when the user holds the fixed handle part 700B, they are used to holding the upper end 731B. The trigger 740B is provided at the upper end of the fixed handle part 700B, which is more in line with the user's usage habit.

[0100] Exemplarily, a second linkage plate 750B is disposed between the trigger 740B and the locking portion 800B, and a trigger rod 741B is disposed between the trigger 740B and the second linkage plate 750B. When the trigger 740B is pressed, the trigger rod 741B drives the second linkage plate 750B to move, so that the second linkage plate 750B drives the locking portion 800B to displace, so as to release the locked state between the locking portion 800B and the limiting portion. Optionally, the second linkage plate 750B is rotatably connected in the fixed handle portion 700B through a second shaft 751B. The second shaft 751B is disposed between the trigger rod 741B and the locking portion 800B. By rotating or swinging the second linkage plate 750B around the second shaft 751B, the displacement of the trigger 740B is transmitted to the locking portion 800B to cause the locking portion 800B to displace. The second linkage plate 750B can be in the shape of a flat plate, a rod, or other special-shaped structures for realizing linkage. In some alternative embodiments, the displacement of the trigger 740B is transmitted to the locking portion 800B through the deformation of the second linkage plate 750B to cause the locking portion 800B to displace.

[0101] Optionally, the trigger 740B is biased (for example, having a biasing member, such as a spring). Optionally, the trigger rod 741B is biased (for example, having a biasing member, such as a spring), and the locking portion 800B is biased (for example, having a biasing member, such as a spring), so that when the user releases the trigger 740B, the locking portion 800B is biased towards the limiting portion. The biasing member releases the biasing force to move the locking portion 800B into the limiting portion. Due to the action of the biasing force, the locking portion 800B is held within the limiting portion. Optionally, at least one of the trigger 740B, the trigger rod 741B, and the locking portion 800B is biased.

[0102] Such as Figure 10As shown, in this embodiment, the locking portion 800B includes a plug portion 820B, a sliding portion 830B, and a shaft shoulder portion 840B. Among them, the diameter of the sliding portion 830B is smaller than that of the plug portion 820B, and the diameter of the sliding portion 830B is smaller than that of the shaft shoulder portion 840B. A chute 803B connecting the first limiting portion 801B and the second limiting portion 802B is further provided on the first linkage plate 810B, and the width of the chute 803B is smaller than the diameters of the first limiting portion 801B and the second limiting portion 802B. In this embodiment, the diameter of the plug portion 820B is larger than the width of the chute 803B, the diameter of the sliding portion 830B is smaller than the width of the chute 803B, and the diameter of the shaft shoulder portion 840B is larger than the width of the chute 803B. Thus, the sliding portion 830B is displaced within the chute 803B, so that the locking portion 800B moves between the first limiting portion 801B and the second limiting portion 802B. Optionally, the locking portion 800B is driven to move in a direction perpendicular to the axis 20A of the central tube. Along the direction from the first linkage plate 810B to the second linkage plate 750B, the plug portion 820B, the sliding portion 830B, and the shaft shoulder portion 840B are arranged in sequence.

[0103] In this embodiment, when the leg portion 330 is in the retracted position, the trigger 740B is released, that is, the user does not trigger the displacement of the trigger 740B. The plug portion 820B of the locking portion 800B enters the first limiting portion 801B. Since the diameter of the plug portion 820B is larger than the width of the chute 803B, the movement of the plug portion 820B and the first limiting portion 801B in the direction of the axis 20A of the central tube is restricted. Moreover, under the action of the biasing force, the locking portion 800B maintains a tendency to move towards the first limiting portion 801B, and there is no relative displacement between the locking portion 800B and the first linkage plate 810B. The locking portion 800B holds the moving collar 311 in the first position.

[0104] When the user triggers the trigger 740B during the retraction of the leg portion 330, the trigger 740B is moved and drives the second linkage plate 750B to displace or deform through the trigger rod 741B, and then drives the locking portion 800B, so that the sliding portion 830B of the locking portion 800B enters the first limiting portion 801B. Since the diameter of the sliding portion 830B is smaller than the width of the chute 803B, the sliding portion 830B can enter the chute 803B, and the axial displacement limit between the locking portion 800B and the first linkage plate 810B is released. The locking portion 800B and the first linkage plate 810B perform relative movement along the axis 20A of the central tube axially. Since the diameter of the shaft shoulder portion 840B is larger than the width of the chute 803B, the displacement of the locking portion 800B perpendicular to the axis 20A of the central tube is restricted.

[0105] In this embodiment, when the movable collar 311 moves downward, it drives the first linkage plate 810B to move downward. The sliding portion 830B slides in the chute 803B until the sliding portion 830B enters the second limiting portion 802B. Exemplarily, when the movable collar 311 moves to the second position, the sliding portion 830B enters the second limiting portion 802B, and the hole wall of the second limiting portion 802B restricts the locking portion 800B from continuing to move upward relative to the first linkage plate 810B. When the user is at the position where the leg portion 330 is in the deployed state and releases the trigger 740B, the plug portion 820B of the locking portion 800B enters the second limiting portion 802B. Since the diameter of the plug portion 820B is greater than the width of the chute 803B, the movement of the plug portion 820B and the second limiting portion 802B in the direction of the axis 20A of the central tube is restricted, that is, the downward movement of the locking portion 800B relative to the first linkage plate 810B is restricted. Moreover, under the action of the biasing force, the locking portion 800B maintains a tendency to move towards the second limiting portion 802B, and there is no relative displacement between the locking portion 800B and the first linkage plate 810B. The locking portion 800B holds the movable collar 311 at the second position.

[0106] In this embodiment, it further includes a driving member 400, and the driving member 400 drives the movable collar 311 to move. In this embodiment, the driving member 400 is an elastic member, such as a spring. When the bracket assembly 300 switches from the deployed state to the retracted state, the elastic member stores energy. When the bracket assembly 300 is held in the retracted state, the elastic member is always in an energy storage state. After the trigger 740B is triggered, the elastic member releases elastic potential energy to drive the movable collar 311 to move, and causes the leg portion 330 to move away from the connecting portion 310, so that the bracket assembly 300 switches from the retracted state to the deployed state.

[0107] For the convenience of user operation, a pull ring 500B is formed on or connected to the movable collar 311. When the user retracts the bracket assembly 300 from the deployed state, the user drives the movable collar 311 to move upward by pulling the pull ring 500B, which is more convenient for the user to hold. Optionally, when the bracket assembly 300 is in the retracted state, when the user carries the lighting device, the pull ring 500B is used as an auxiliary carrying position. Exemplarily, the user can choose to use only the fixed handle portion 700B as the carrying position to carry the lighting device, or can also choose both the fixed handle portion 700B and the pull ring 500B as the carrying positions to carry the lighting device simultaneously to achieve two-handed operation. Optionally, the pull ring 500B can also be used as a hanging component to hang the lighting device 10B at the required position, thereby performing storage or hanging work.

[0108] The foregoing has shown and described the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any way, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present application.
