Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a lighting device. Background Art

[0002] Generally, as a common support device, a support frame can be used as a shooting device, a surveying and mapping device, and a lighting device. When the support frame is used as a lighting device, the support frame generally includes a deployable tripod body and a central axis. A lamp head is installed at one end of the central axis, and the tripod body is rotatably connected to the central axis. The tripod body rotates circumferentially relative to the central axis. During the rotation, the frictional force between the tripod body and the central axis is used to fix the circumferential swing orientation of the lamp head. However, as the number of rotations increases, the rotating contact surface between the tripod body and the central axis will be worn, making the tripod unable to stably fix at the target rotation angle. Summary of the Utility Model

[0003] The utility model aims to provide a lighting device to solve the technical problems of the traditional lighting device with a conducting wire, such as the conducting wire is stretched and cannot return to its original position as the two components move relative to each other at the connection position of different components, resulting in poor electrical contact and short service life.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A lighting device, comprising:

[0006] A central axis having an installation end and a support end opposite to each other along its axial direction. The support end is provided with a first stop wall and a second stop wall, and the first stop wall and the second stop wall are opposite to each other and spaced along the axial direction of the central axis;

[0007] A lamp head connected to the installation end;

[0008] A support plate rotatably arranged circumferentially along the central axis between the first stop wall and the second stop wall;

[0009] A reset member arranged between the first stop wall and the support plate and storing a reset force. The reset force released by the reset member continuously acts on the support plate and abuts the support plate against the second stop wall;

[0010] A tripod, comprising a plurality of legs deployed at an angle. Each leg has a movable end and a free end. The movable end is connected to the support plate, and the free end is used to support the lighting device on a support surface.

[0011] In one embodiment, a bottom end surface and a limiting shaft are provided at the bottom of the supporting end. The limiting shaft includes a shaft body and a convex platform connected to the end of the shaft body. The end of the shaft body facing away from the convex platform is in contact with the bottom end surface. The convex platform extends radially along the shaft body and forms a step surface on the side of the convex platform facing the bottom end surface. Among them, the reset member surrounds the shaft body, the support plate is penetrated by the shaft body, the support plate rotates around the shaft body, and one of the step surface and the bottom end surface is the first stop wall and the other is the second stop wall.

[0012] In one embodiment, a receiving groove covered by the first stop wall is provided on one end surface of the support plate, and the reset member is received in the receiving groove.

[0013] In one embodiment, the opening of the receiving groove faces the mounting end, and an installation groove is provided on the side of the support plate facing away from the mounting end. The convex platform is received in the installation groove, and the convex platform does not protrude from the end surface of the support plate facing away from the mounting end.

[0014] In one embodiment, a hollow column is protrudingly provided on the bottom wall of the receiving groove along the axial direction of the central axis, and the hollow column is sleeved on the outer wall of the shaft body.

[0015] In one embodiment, the reset member includes a plurality of corrugated washers stacked in sequence along the axial direction of the central axis.

[0016] In one embodiment, the reset member includes a telescopic spring, and the telescopic spring is always compressed along the axial direction of the central axis to accumulate elastic force.

[0017] In one embodiment, the movable end is rotatably connected to the side circumference of the support plate. The movable end flips relative to the support plate towards the central axis, and at the same time drives the free ends to switch from a supporting state of being away from each other to a closing state of being close to each other, so that the plurality of legs switch from an angularly unfolded state to a side-by-side closing posture.

[0018] In one embodiment, the tripod further includes a sleeve and a plurality of pin members. The sleeve is sleeved outside the central axis and can rotate circumferentially. The sleeve is slidably connected to the central axis along the axial direction of the central axis. The pin member has a rotating end and a fixed end opposite to each other along its axial direction. The rotating end is rotatably connected to the side circumference of the sleeve, and the fixed ends are supported away from each other on the supporting surface. The legs are connected between the support plate and the pin member. The movable end is rotatably connected to the side circumference of the support plate, and the free end is rotatably connected to the inside of the pin member.

[0019] In one embodiment, the lighting device further includes a movable rod having a first connection end and a second connection end opposite to each other along its axial direction. The first connection end is rotatably connected to the mounting end, and the second connection end is connected to the lamp head. The first connection end can rotate relative to the mounting end until the movable rod is juxtaposed and close to the central axis. When multiple legs are in a juxtaposed and closed posture, the lamp head simultaneously latches the bottom end of the tripod.

[0020] As can be seen from the above technical solutions, the embodiments of the present utility model have at least the following advantages and positive effects:

[0021] The present utility model provides a lighting device. The central axis rotates circumferentially relative to the support plate, driving the lamp head to rotate circumferentially relative to the tripod to change the circumferential illumination orientation of the lamp head. In order to stabilize the target circumferential illumination orientation of the lamp head, a first stop wall and a second stop wall are provided opposite to each other along the axial direction of the central axis at the support end. A reset member is disposed between the first stop wall and the support plate and stores a reset force. The reset force released by the reset member continuously acts on the support plate and presses the support plate against the second stop wall, thereby increasing the rotational damping between the support plate and the support end. On the one hand, it restricts the circumferential rotational movement of the lamp head in a certain stationary state. On the other hand, it increases the stability of the lamp head and the tripod in this relatively stationary state, enhances the support stability of the tripod in the lighting device, and enables the user to obtain a stable light source.

Detailed implementation manners

[0032] Typical implementation manners reflecting the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different implementation manners, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

[0033] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0034] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "set", "connected" and "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0035] Combined reference Figure 1 and Figure 2 , the present application provides an illumination device 10 that can be switched between a deployed state and a stored state. In this embodiment, Figure 1 illustrates the illumination device 10 in the stored state. At this time, the illumination device 10 can be held by the user for carrying and provide an illumination function. For example, the user can obtain illumination light by holding the illumination device 10, which is convenient for the user to move at night. At the same time, when the illumination device 10 is in the stored state, the volume and occupied space of the illumination device 10 are small, which is convenient for storage and carrying. Figure 2 illustrates the illumination device 10 in the deployed state. The illumination device 10 in the deployed state has a higher illumination height and a larger illumination range. At this time, the user can hold it with bare hands to provide illumination for a large range of moving space during outdoor camping, and use it as a mobile street lamp or a detection lamp when walking at night, which is not only convenient for guiding illumination, but also convenient for the user to observe the surrounding environment. Or, referring to Figure 3 , in other usage scenarios, the illumination device 10 can be further deployed into a bracket state to place the illumination device 10 on a flat or uneven support surface to provide an illumination function. For example, when reading or using a computer at home at night, appropriate lighting is required to protect the eyes from strong light damage. At this time, the illumination device 10 can be supported on the desktop and used as a table lamp. It should be understood that the illumination device 10 does not necessarily need to be deployed into the Figure 3 shown bracket state, as long as it satisfies that the illumination device 10 can be switched between the Figure 1 shown folded and stored state and the Figure 2 shown deployed state. In addition, when the support body of the illumination device 10 is thick enough, the user can also directly support the Figure 2 shown illumination device 10 in the deployed state on the support surface.

[0036] Combined reference Figure 1 and Figure 2The lighting device 10 of the present application includes a support rod 100, a movable rod 200 and a lamp holder 300 connected in sequence, the movable rod 200 is movably connected to the support rod 100, the lamp holder 300 is used as a lighting component of the lighting device 10 to emit lighting light to provide a light source for the user, and the lamp holder 300 is connected to the free end of the movable rod 200 (the other end of the movable rod 200 relative to the support rod 100). The movable rod 200 moves relative to the support rod 100, so that the entire lighting device 10 can switch freely between the unfolded state and the folded state. Preferably, the movable rod 200 of this embodiment is rotatably connected to the outer side of the support rod 100, and the movable rod 200 pitches and swings relative to the support rod 100 along the axial direction of the support rod 100 until the movable rod 200 and the support rod 100 are close to each other to realize the folding and storage of the entire lighting device 10. It should be understood that, in other embodiments, firstly, the lamp head 300 can be directly connected to the support rod 100 and can also constitute the lighting device 10. In the present application, the presence or absence of the movable rod 200 is not limited. Secondly, in other embodiments, the pitching and tilting angle of the movable rod 200 relative to the support rod 100 is not limited, that is, the movable rod 200 may not necessarily swing to be close to the support rod 100 to achieve the folded state of the lighting device 10. That is, in the present application, whether the lighting device 10 is folded and stored is not limited.

[0037] Specifically, in the present embodiment, the support rod 100 as a supporting body has a supporting end 101 and a mounting end 102 which are opposite to each other along its axial direction. When the lighting device 10 is in the unfolded state, the support rod 100 can support the lighting device 10 on the supporting surface; the movable rod 200 has a first connecting end 201 and a second connecting end 202 which are opposite to each other along its axial direction, and the first connecting end 201 is connected to the mounting end 102; the second connecting end 202 is connected to the lamp holder 300. Preferably, in the present embodiment, the first connecting end 201 is rotatably connected to the mounting end 102. When the first connecting end 201 rotates relative to the mounting end 102, the angle between the movable rod 200 and the support rod 100 changes, and the movable rod 200 can be flipped to be side by side with the support rod 100. At this time, the movable rod 200 is folded and stored on the side of the support rod 100, so that the lighting device 10 switches from the unfolded state to the stored state. Figure 1 As shown, when the lighting device 10 is in the storage state, that is, the movable rod 200 and the support rod 100 are in a side-by-side close posture, the lamp head 300 is buckled on the support end 101. Here, buckling means that the two are tightly combined, which can be achieved by buckling, hooking, sticking, magnetic attraction, etc.; the lamp head is buckled on the support end 101, including but not limited to the lamp head 300 can be buckled on the side, edge, and bottom of the support end 101.

[0038] Preferably, in this embodiment, in combination with reference Figure 3 and Figure 4, the support rod 100 includes a central axis 110, a support plate 120, a reset member 130, and a tripod 140. The opposite ends of the central axis 110 along its axial direction respectively correspond to the support end 101 and the mounting end 102 described above. The lamp head 300 is connected to the mounting end 102 through the movable rod 200. The lamp head 300 is mounted and connected to the central axis 110 and is circumferentially limited (here, the circumferential limitation means that the lamp head 300 cannot rotate relative to the central axis 110 around the circumference of the central axis 110). The support plate 120 is rotatably connected to the support end 101 along the circumference of the central axis 110. The reset member 130 is disposed between the support end 101 (central axis 110) and the support plate 120 and accumulates a reset force along the axial direction of the central axis 110. This reset force continuously acts on the support plate 120 and abuts the support plate 120 against the support end 101 of the central axis 110. The tripod 140 is connected to the side circumference of the support plate 120 and is circumferentially limited (here, the circumferential limitation means that the tripod 140 cannot rotate relative to the support plate 120 around the circumference of the central axis 110). The tripod 140 can be in an unfolded support state to support the lighting device 10 on the support surface.

[0039] Specifically, with reference to Figures 5 - 7 , a first stop wall 111 and a second stop wall 112 are provided at the support end 101 of the central axis 110. The first stop wall 111 and the second stop wall 112 are opposite and spaced along the axial direction of the central axis 110. The support plate 120 is clamped and installed between the first stop wall 111 and the second stop wall 112. The reset member 130 is disposed between the first stop wall 111 and the support plate 120. Along the axial direction of the central axis 110, the reset force released by the reset member 130 continuously acts on the support plate 120 and abuts the support plate 120 against the second stop wall 112. The action of the reset force is converted into the extrusion force between the surfaces of the support plate 120 and the second stop wall 112 in contact, increasing the extrusion force between the support plate 120 and the second stop wall 112 to increase the rotational damping between the support plate 120 and the central axis 110.

[0040] In the present application, the lamp holder 300 is connected to the mounting end 102 of the central axis 110 and is circumferentially limited, and the tripod 140 is connected to the support plate 120 and is circumferentially limited. Therefore, along the circumference of the central axis 110, the central axis 110 and the support plate 120 rotate relative to each other circumferentially, synchronously driving the lamp holder 300 to rotate circumferentially relative to the tripod 140; when the central axis 110 and the support plate 120 are circumferentially stationary relative to each other, the lamp holder 300 is circumferentially stationary relative to the tripod 140, and the circumferential illumination direction of the lamp holder 300 is fixed. A reset member 130 is provided between the central axis 110 and the support plate 120, and the reset force released by the reset member 130 along the central axis 110 is converted into a abutting force between the central axis 110 and the support plate 120, increasing the rotational damping therebetween. On the one hand, it restricts the circumferential dislocation of the lamp holder 300 in a certain stationary state, and on the other hand, it increases the stability of the lighting device 10 when the lamp holder 300 and the tripod 140 are in this relatively stationary state. The support stability of the tripod 140 in the lighting device 10 is enhanced, enabling the user to obtain a stable light source.

[0041] It should be understood that in other embodiments, the lamp holder 300 and the mounting end 102 may also rotate relative to each other circumferentially, as long as it is satisfied that when the lamp holder 300 and the mounting end 102 can stay at a certain fixed rotation angle during the rotation process, the lamp holder 300 and the central axis 100 can rotate circumferentially synchronously together, and the two rotate synchronously relative to the support plate 120 and the support frame 140. That is, the present application does not limit whether the lamp holder 300 and the mounting end 102 are circumferentially limited.

[0042] Preferably, in the present embodiment, referring to Figures 5 - 7 , a bottom end surface 113 and a limiting shaft 103 are provided at the bottom of the support end 101. The limiting shaft 103 includes a shaft body 114 and a boss 115 connected to the end of the shaft body 114. The other end of the shaft body 114 away from the boss 115 is connected to the bottom end surface 113. The boss 115 extends radially along the shaft body 114 and forms a step surface 116 on the side of the boss 115 facing the bottom end surface 113; the reset member 130 surrounds the shaft body 114, and the support plate 120 is penetrated by the shaft body 114, and the support plate 120 rotates relative to the central axis 110 around the shaft body 114. As Figure 5 shown, in the present embodiment, the support plate 120 abuts against the step surface 116. The step surface 116 of the boss 115 is the second stop wall 112, and the bottom end surface 113 is the first stop wall 111. The first stop wall 111 is closer to the mounting end 102 along the axial direction of the central axis 110 than the second stop wall 112 ( Figure 4As shown. It should be understood that in other embodiments, the support plate 120 may also abut against the bottom end surface 113. In this case, the bottom end surface 113 is the second stop wall 112, the stepped surface 116 is the first stop wall 111, and the first stop wall 111 is farther from the mounting end 102 than the second stop wall 112 along the axial direction of the central axis 110. It should be noted that in this application, the relative distances of the first stop wall 111 and the second stop wall 112 from the mounting end 102 are not limited. The first stop wall 111 and the second stop wall 112 have relative meanings. In this application, for the convenience of description and understanding, the surface against which the support plate 120 abuts is defined as the second stop wall 112, and the other is defined as the first stop wall 111.

[0043] It should be further understood that the limiting shaft 103 is only a specific way to realize the circumferential rotation setting of the support plate 120. In other embodiments, an annular groove circumferentially around the central axis 110 is provided on the side circumference of the bottom end surface 113, and a corresponding annular protrusion is provided on the support plate 120. The annular protrusion being engaged in the annular groove can also realize the circumferential rotation of the support plate 120. That is, the structural manner for realizing the circumferential rotation of the support plate 120 in this application is not limited.

[0044] Preferably, with reference to Figure 5 and Figure 6 , a receiving groove 121 is provided on the end surface of the support plate 120 facing the bottom end surface 113 (facing the mounting end 102). The opening of the receiving groove 121 faces the bottom end surface 113, and the first stop wall 111 covers the opening of the receiving groove 121. The reset member 130 is received and disposed in the receiving groove 121 and is located between the bottom wall of the receiving groove 121 and the first stop wall 111. Such a design protects the reset member 130 from being isolated from the outside world and being damaged by bumps, erosion, etc. from the external environment. Further, with reference to Figure 5 and Figure 7 , an installation groove 122 is provided on the end surface of the support plate 120 facing away from the receiving groove 121 (facing away from the mounting end 102). The installation groove 122 accommodates the convex platform 115, so that the convex platform 115 does not protrude from the end surface of the support plate 120 facing away from the mounting end 102. The provision of the installation groove 122, on the one hand, makes the structure of the support plate 120 more compact, and on the other hand, the convex platform 115 is protected by the installation groove 122 and does not come into contact with other components, thereby reducing wear.

[0045] It should be understood that, firstly, without considering the accommodation of the reset member 130 and the boss 115, in the present application, whether the receiving groove 121 and the mounting groove 122 are provided or not is not limited. Secondly, in other embodiments, when the second retaining wall 112 is closer to the mounting end 102 than the first retaining wall 111, and the support plate 120 is against the bottom end surface 113 of the support end 101, the receiving groove 121 is provided on the end surface of the support plate 120 away from the bottom end surface 113 (away from the mounting end 102), and the opening of the receiving groove 121 is away from the bottom end surface 113. In this case, the mounting groove 122 does not need to be provided. When the receiving groove 121 is provided deep enough, the boss 115 is directly accommodated in the receiving groove 121. Therefore, in the present application, the opening position of the receiving groove 121 is not limited, and the receiving groove 121 can be provided on any end surface of the support plate 120 that is opposite to the axial direction of the central axis 110.

[0046] Preferably, in combination with reference Figure 5 and Figure 6 , the bottom wall of the receiving groove 121 is provided with a hollow column 123 protruding along the axial direction of the central axis 110, the hollow column 123 is sleeved on the outer wall of the shaft body 114, and the reset member 130 surrounds the outer wall of the hollow column 123. The above design increases the connection stability between the support plate 120 and the support end 101. Of course, without considering the connection stability, in other embodiments, whether the support plate 120 is provided with the hollow column 123 is not limited.

[0047] Finally, preferably, reference Figure 4, in this embodiment, the reset member 130 includes a plurality of corrugated washers 131 stacked axially in sequence along the central axis 110. The user can, according to needs, change the magnitude of the reset force by increasing or decreasing the number of corrugated washers 131. It should be noted here that the corrugated washer 131 is also called a wave washer, which is a circular thin sheet with a regular wave shape and is generally used to prevent loosening and mitigate impact, and needs to have good elasticity and impact resistance and other properties. It should be understood that stacking a plurality of corrugated washers 131 to form the reset member 130 is only a specific way to realize the reset member 130 accumulating the reset force. For example, in one embodiment, the reset member 130 includes a telescopic spring sleeved on the outer sidewall of the shaft body 114. The telescopic spring is compressed along the axial direction of the central axis 110 to accumulate elastic force, and this elastic force continuously acts on the support plate 120 and abuts the support plate 120 against the second stop wall 112. In another embodiment, the reset member 130 includes a first magnet and a second magnet. The first magnet is provided on the support plate 120, and the second magnet is provided on the first stop wall 111. At this time, the first magnet and the second magnet repel each other and abut the support plate 120 against the second stop wall 112. That is, in this application, the implementation manner of the reset member 130 is not limited. The reset member 130 includes but is not limited to a plurality of corrugated washers 131, a telescopic spring, and two magnets. When the reset member 130 is a plurality of corrugated washers 131 or a spring, the user can apply a force along the axial direction of the central axis 110 to squeeze the corrugated washer 131 or the spring to deform and accumulate elastic force to be installed between the first stop wall 111 and the second stop wall 112.

[0048] Preferably, with reference to Figure 3 and Figure 4 , in this embodiment, the tripod 140 includes a sleeve 141, a plurality of pin members 142, and a plurality of legs 143. The number of pin members 142 and legs 143 is the same and corresponds one by one. The sleeve 141 is sleeved on the outer side of the central axis 110 and can rotate circumferentially. The sleeve 141 is slidably connected to the central axis 110 along the axial direction of the central axis 110; the pin member 142 has a rotating end 1421 and a fixed end 1422 opposite to each other along its axial direction. The rotating end 1421 is rotatably connected to the side circumference of the sleeve 141, and the fixed ends 1422 are supported on the support surface away from each other; the leg 143 is connected between the support plate 120 and the pin member 142. The leg 143 has a movable end 1431 and a free end 1432 opposite to each other along its axial direction. The movable end 1431 is rotatably connected to the side circumference of the support plate 120, and the free end 1432 is rotatably connected to the inner side of the pin member 142. Above, a plurality of pin members 142 can be switched between a folded state ( Figure 2 ) and an unfolded state ( Figure 3 ). Correspondingly, the legs 143 are synchronously driven by the pin members 142 to rotate and are switched between a folded state ( Figure 2 ) and an unfolded state ( Figure 3 ). Specifically, with reference to Figures 2 to 3, when the rotating end 1421 flips towards the outside of the sleeve 141, it simultaneously drives multiple fixed ends 1422 to switch from a state of approaching and closing to a state of supporting away from each other. Synchronously, the pin member 142 drives the corresponding connected free ends 1432 to switch from a state of approaching and closing to a state of supporting away from each other, and the movable end 1431 flips outwards relative to the support plate 120. Thus, multiple pin members 142 and multiple legs 143 are both switched from a closed state ( Figure 2 ) to a supporting state ( Figure 3 ), so that the tripod 140 is switched from a storage state to an unfolded state. At this time, the legs 143 serve as intermediate support frames, making the unfolded state of the entire tripod 140 more stable. The sleeve 141 and the support plate 120 rotate circumferentially synchronously to drive the pin members 142 and the legs 143 to rotate synchronously.

[0049] It should be understood that, first, in other embodiments, the tripod 140 may not include the sleeve 141 and the pin members 142. At this time, the tripod 140 is directly supported on the support surface by multiple legs 143 that are unfolded at an angle. The movable ends 1431 of the legs 143 are rotatably connected to the side circumference of the support plate 120. The movable ends 1431 flip towards the central axis 110 relative to the support plate 120, and at the same time drive the free ends 1432 to switch from a state of supporting away from each other to a state of approaching and closing, so that multiple legs 143 are switched from an angularly unfolded state to a posture of being side by side and closed. In this embodiment, when multiple legs 143 are in a side-by-side closed state, the free ends 1432 approach each other and are circumferentially abutted against the outer wall of the central axis 110, and multiple legs 143 surround the outer wall of the central axis 110. Second, in other embodiments, the movable ends 1431 may also be fixedly connected to the side circumference of the support plate 120, multiple legs 143 are in an angularly unfolded state, and the free ends 1432 are directly used to support on the support surface, and the tripod 140 cannot be stored and closed. Therefore, in this application, without considering the more stable and firm support state, the setting of the sleeve 141 and multiple pin members 142 is not limited. Without considering whether the tripod 140 can be stored, the rotational connection between the movable ends 1431 of the legs 143 and the support plate 120 is not limited.

[0050] Preferably, referring to Figure 1 , in this embodiment, when the entire lighting device 10 is in a fully stored state, that is, the tripod 140 is closed and the movable rod 200 and the support rod 100 are side by side and close together, the lamp head 300 is buckled on the end face of the support end 101 and at the same time buckled on the bottom end of the tripod 140. To further stabilize the fully stored posture of the entire lighting device 10 and the closed posture of the tripod 140. It should be understood that in other embodiments, without considering the storage stability of the lighting device 10, the position where the lamp head 300 buckles on the support end 101 is not limited, and whether the lamp head 300 buckles on the support end 101 is also not limited.
