- each of the support rods 160 is provided with first fixing portion 163
- each of the support legs 150 is provided with second fixing portion 154 .
- the base assembly 100 further includes tension spring 180 . Two ends of the tension spring 180 are respectively connected to the first fixing portion 163 and the second fixing portion 154 .

- the hook and the post are only illustrative of this embodiment to facilitate understanding of this solution and should not constitute a specific limitation on the embodying form of the first fixing portion 163 and the second fixing portion 154 .
- the tension spring 180 is configured to accumulate an elastic force when the base assembly 100 is in the folded state.
- the tension spring 180 is also configured to release the elastic force to unfold the support leg 150 when the support leg 150 is unlocked.
- the tension spring 180 can be understood to be located between the first connecting end 161 and the rotating end 151 . Based on the mounting position of the tension spring 180 , in the folded state, the tension spring 180 is in an extended state and accumulates an elastic force.
- the support legs 150 When the support legs 150 are in the folded state, the distance between the first fixing portion 163 and the second fixing portion 154 increases, and the tension spring 180 is deformed under tension. The tension spring 180 generates a pulling force on the first fixing portion 163 and the second fixing portion 154 . At this time, the support legs 150 receive an outward support force, causing the support legs 150 to be unfolded outward. However, the bottom of the support leg 150 is provided with the first locking element 171 or the second locking element 172 , and the first locking element 171 is engaged with the second locking element 172 , so the support leg 150 cannot be unfolded. Thus, the support leg 150 is kept in the folded state under the action of the locking structure 170 .
- the pressing portion 174 Since the other end of the second locking element 172 is provided with the pressing portion 174 , when the pressing portion 174 is pressed by a force, the pressing portion 174 is displaced. The locking portion 173 loses the locking effect with the first locking element 171 . Thus, the support leg 150 is unfolded under the force of the support rod 160 , such that the support leg 150 is in the unfolded state.
- the three support legs 150 When the three support legs 150 are in the unfolded state, the three support legs 150 can be manually combined to reset. During resetting, the first locking elements 171 contact the locking portions 173 respectively. Under the action of the locking portions 173 , the pressing portion 174 is displaced, such that the support legs 150 are successfully and completely reset to the folded state. The second locking element 172 resets under the action of the elastic element 175 and locks the first locking elements 171 .
- the second fixing portion 154 can be provided on the support leg 150 or the sliding element 140 .
- the tension spring 180 may also be located between the first connecting end 161 and the support end 152 .
- the tension spring 180 is compressed in the folded state to accumulate an elastic force. Since the tension spring 180 has the elastic force to restore an original state, the tension spring can act on the first fixing portion 163 to make the first fixing portion 163 tend to rotate away from the support end 152 , that is, tend to drive the support leg 150 to be unfolded. It should be noted that all the above embodiments of the tension spring 180 are also applicable to the case where the support rod 160 is provided between the main body 120 and the support leg 150 .

- Referring to
FIGS. 1 and 2 , the present disclosure provides lighting device 1. The lighting device 1 includesbase assembly 100,telescopic rod 200, andlighting assembly 300. Thebase assembly 100 is configured to fix and support thetelescopic rod 200 and thelighting assembly 300. Thetelescopic rod 200 is provided between thebase assembly 100 and thelighting assembly 300. Thetelescopic rod 200 has an adjustable axial length. It can be understood that thetelescopic rod 200 is extensible and retractable to change the lighting height of thelighting assembly 300 according to user needs. It should be noted that thebase assembly 100 can be held by the user, and thelighting assembly 300 can be any light-emitting device. Thelighting assembly 300 includes, but is not limited to a light-emitting diode (LED) light, a flashlight, a neon light, etc. Alternatively, thelighting assembly 300 may include a light-emitting panel formed by a plurality of parallel and/or series LEDs. -
FIG. 1 shows that the lighting device 1 is in a folded state. In the folded state, thetelescopic rod 200 is not extended, thelighting assembly 300 approaches thebase assembly 100, and the overall size of the lighting device 1 is minimized. In the folded state, the lighting device 1 can be effectively folded to facilitate carrying, and the lighting device 1 can also be used as a flashlight in the folded state. When thetelescopic rod 200 is extended, the lighting device 1 is switched from the folded state shown inFIG. 1 to an unfolded state shown inFIG. 2 . In this state, the user can hold thebase assembly 100 such that light emitted by thelighting assembly 300 can shine farther, for example, for outdoor lighting. - The
telescopic rod 200 includes fixedend 210 andfree end 220 that are arranged opposite to each other. Thefixed end 210 is connected to thebase assembly 100, and thefree end 220 is connected to thelighting assembly 300. Thefree end 220 can be retracted relative to thefixed end 210 along a length extension direction of the telescopic rod 200 (that is, an axial direction of the telescopic rod 200) to change the distance between thelighting assembly 300 and thebase assembly 100 to adapt to lighting scenes at different heights. In specific use, the user can appropriately increase the length of thetelescopic rod 200 according to different lighting scenes. When the lighting device 1 is folded, thetelescopic rod 200 is retracted to store thelighting assembly 300 and thebase assembly 100 together. The design can reduce the occupied space of the lighting device 1 and make the lighting device easy to carry. - In order to extend and retract the
telescopic rod 200,FIG. 2 shows that thetelescopic rod 200 includes a plurality of rod portions connected head to tail. The inner diameters of the plurality of rod portions decrease from thefixed end 210 to thefree end 220. That is, when thetelescopic rod 200 is in an extended state, the inner diameters of the plurality of rod portions decrease from thebase assembly 100 to thelighting assembly 300. That is, the inner diameter of the rod portion closest to thebase assembly 100 is the largest, and the inner diameter of the rod portion closest to thelighting assembly 300 is the smallest. A rod portion with a smaller inner diameter can be accommodated in a rod portion with a larger inner diameter. - For easy understanding, any two adjacent rod portions are defined as a first rod portion and a second rod portion. The first rod portion approaches the
lighting assembly 300, and the second rod portion approaches thebase assembly 100. In order to prevent the first rod portion from separating from the second rod portion in the extension process, a first rubber pad is provided at the outer side of the tail of the first rod portion, and a second rubber pad is provided at the inner side of the head of the second rod portion. The outer diameter of the first rubber pad is larger than the inner diameter of the second rubber pad. When the tail of the first rod portion is nested inside the head of the second rod portion and the first rod portion extends away from the second rod portion, the first rubber pad is adhered to the second rubber pad to prevent the first rod portion from sliding out of the second rod portion during the extension process. It should be noted that the rubber pad can be replaced by any other soft material that can absorb vibration. Through adhesive glue or by other means, the first rubber pad is connected to the first rod portion, and the second rubber pad is connected to the second rod portion to achieve stability after the first rubber pad is connected to the first rod portion and the second rubber pad is connected to the second rod portion. Thetelescopic rod 200 can be made of aluminum, aluminum alloy, copper, iron, or a composite material, etc. It should be noted that in each embodiment of the present application, the head refers to an end adjacent tomain body 120 and far from thebase body 110, and the tail refers to the end far from themain body 120 and adjacent tobase body 110. - Referring to
FIGS. 3 and 4 ,FIGS. 3 and 4 show that thelighting assembly 300 is rotatably connected to thefree end 220 and thelighting assembly 300 is rotatable relative to thefree end 220, thereby switching the lighting direction of thelighting assembly 300.FIGS. 3 and 4 show that thelighting assembly 300 is rotatable axially and radially around thetelescopic rod 200, that is, thelighting assembly 300 is rotatable axially and radially to adjust the height of thelight assembly 300. - The lighting device 1 realizes the extension and retraction of the
lighting assembly 300 through thetelescopic rod 200, such that the lighting device 1 can achieve a wide height adjustment range and is convenient for the storage and carrying of the lighting device 1. Since thelighting assembly 300 is movably connected to thefree end 220, thelighting assembly 300 is rotatable axially and radially around thefree end 220. That is, thelighting assembly 300 can realize the angle adjustment in horizontal and vertical directions to meet different lighting angles, thereby improving the user experience. - It should be noted that when the height and lighting angle of the
lighting assembly 300 are adjusted, thebase assembly 100 can also be switchable from the folded state shown inFIG. 2 to the unfolded state shown inFIG. 3 . - Referring to
FIG. 5 , thebase assembly 100 includes mountingstructure 100 a andsupport structure 100 b. The mountingstructure 100 a is configured to fix thetelescopic rod 200. Thesupport structure 100 b is slidably provided on the mountingstructure 100 a and is rotatable relative to the mountingstructure 100 a to fold and unfold thesupport structure 100 b. - The mounting
structure 100 a includes thebase body 110, themain body 120, and guiderod 130 provided between thebase body 110 and themain body 120. Theguide rod 130, thebase body 110, and themain body 120 can be combined and connected by one or more means, such as fasteners, bolts, screws, rivets, and viscous substances, or can be integrally formed, which is not limited herein. Thebase body 110 may be configured to be supported on a flat or uneven surface. Themain body 120 may be configured to fix thefixed end 210 of thetelescopic rod 200. Theguide rod 130, as an intermediate connector, is configured to space thebase body 110 and themain body 120. Themain body 120 and theguide rod 130 may be hollow-through structures. When themain body 120 and theguide rod 130 are hollow-through structures, thefixed end 210 of thetelescopic rod 200 can run through themain body 120 and theguide rod 130, and thefixed end 210 running through themain body 120 and theguide rod 130 can be extended and fixed to thebase body 110. In this way, thetelescopic rod 200 can be stored in an inner space of themain body 120 and an inner space of theguide rod 130. Themain body 120 and theguide rod 130 may also be non-hollow-through structures. When themain body 120 and theguide rod 130 are non-hollow-through structures, thefixed end 210 is directly connected to themain body 120. - The hollow structure of the
main body 120 can be provided therein withbattery 100 c andcircuit board 100 d. Thebattery 100 c is electrically connected to thecircuit board 100 d. In an embodiment, thecircuit board 100 d is provided with a charging interface, and themain body 120 is provided with a charging through-hole that runs through an outer wall. The charging through-hole exposes the charging interface, such that an external power supply device can be connected to the charging interface through the charging through-hole to charge the battery. Of course, in this embodiment, thecircuit board 100 d can also be provided with a power output interface, and themain body 120 is also provided with a power output through-hole that runs through the outer wall. The power output through-hole exposes the power output interface, and the power output interface can be connected to an external electric device (such as a mobile phone or a tablet) to charge the electric device. - The
main body 120 may also be provided with sealingplug 121. The sealingplug 121 is configured to seal the charging interface and the power output interface when they are idle to prevent water or ash from entering the charging interface and the power output interface to cause poor contact. In addition, themain body 120 may also be provided withcontrol key 122. Thecontrol key 122 may be configured to control the circuit connection and disconnection of thelighting assembly 300. For example, thecontrol key 122 can be directly configured to control the connection and disconnection of thecircuit board 100 d and thelighting assembly 300. It should be noted that thecircuit board 100 d can also be provided in thebase body 110, which is not limited herein. - The
support structure 100 b includes slidingelement 140 and supportlegs 150. The slidingelement 140 is slidably connected to theguide rod 130. There are a plurality ofsupport legs 150. For example,FIG. 5 shows that there are threesupport legs 150. It can be understood that in other embodiments, there may be two ormore support legs 150. Each of thesupport legs 150 is provided withrotating end 151 and support end 152 that are arranged opposite to each other. Therotating end 151 is rotatably connected to the slidingelement 140, and thesupport end 152 may be configured to be supported on a flat or uneven support surface. Thesupport end 152 can be provided with a magnetic element to be magnetically attracted to a support surface of a metal structure. It should be noted that the slidingelement 140 is slidable toward thebase body 110 to drive the plurality of support ends 152 away from each other, such that thebase assembly 100 is in an unfolded state. The slidingelement 140 is also slidable toward themain body 120 to drive the plurality of support ends 152 to approach each other, such that thebase assembly 100 is in a folded state.FIG. 1 shows that when thebase assembly 100 is in the folded state, the outer surface of each of thesupport legs 150 is flush with the outer surface of themain body 120. In the folded state, the appearance ofbase assembly 100 is integral.FIG. 5 also shows that each of thesupport legs 150 is provided withreflective sticker 153 outside thesupport end 152. Thereflective sticker 153 reflects light or emits fluorescence in a dark environment to make it easily found. - The sliding
element 140 is slidable freely along an axial direction of theguide rod 130. The slidingelement 140 may move to the bottom to contact thebase body 110. In this case, the slidingelement 140 is limited by thebase body 110 and will not slide off theguide rod 130. The slidingelement 140 is also movable to a top to contact themain body 120. In this case, the slidingelement 140 is limited by themain body 120 and will not slide off theguide rod 130. In order to realize the stable connection between the slidingelement 140 and theguide rod 130, the slidingelement 140 can be sleeved on the outer wall of theguide rod 130. It can be understood that in other embodiments, the slidingelement 140 may include a plurality of independent sliding portions. The sliding portions are respectively connected to thesupport legs 150 and are slidably provided on theguide rod 130. - A side of the
base body 110 facing themain body 120 is provided withbuffer pad 123 that is configured to contact the slidingelement 140. Thebuffer pad 123 may be an elastic ring such as a silicon rubber ring, a rubber ring, etc. Thebuffer pad 123 is configured to alleviate the impact of the slidingelement 140 on thebase body 110 when the slidingelement 140 slides toward thebase body 110 to avoid damage to either part. Of course, a side of themain body 120 facing thebase body 110 can also be provided with a damping pad that is configured to contact the slidingelement 140. The damping pad may also be an elastic ring such as a silicon rubber ring or a rubber ring. The damping pad is configured to alleviate the impact of the slidingelement 140 on themain body 120 when the slidingelement 140 slides toward themain body 120 to avoid damage to either part. - When the sliding
element 140 slides along theguide rod 130, the slidingelement 140 can drive thesupport legs 150 to be folded and unfolded. Therefore, the user only needs to move the slidingelement 140 to facilitate user operation. In order to realize the above function, thesupport structure 100 b further includessupport rods 160. Each of thesupport rods 160 includes first connectingend 161 and second connectingend 162 that are arranged opposite to each other. The first connectingend 161 is rotatably connected to thesupport leg 150, and the second connectingend 162 is rotatably connected to thebase body 110. Therefore, thesupport rod 160 is rotatable with the first connectingend 161 as a rotation shaft, and thesupport rod 160 is also rotatable with the second connectingend 162 as a rotation shaft. Therotating end 151, the first connectingend 161, and the second connectingend 162 form a triangular structure. That is, thesupport leg 150, thesupport rod 160, the slidingelement 140, and theguide rod 130 form a triangular structure to achieve high stability and strength. - When the sliding
element 140 is forced to move toward thebase body 110, the distance between therotating end 151 and the second connectingend 162 is reduced. A downward pressing force of the slidingelement 140 and an upward supporting force of thebase body 110 generate a resultant force toward the first connectingend 161. Thesupport leg 150 is moved away from thebase body 110 under the action of the resultant force. In this way, thesupport legs 150 are unfolded to increase a radius of a ground support point. The design effectively increases the standing stability of the lighting device 1, such that the lighting device 1 can stand stably when tilted. It should be noted that the slidingelement 140 and theguide rod 130 are limited in a peripheral direction, such that the slidingelement 140 is limited to rotate in the peripheral direction relative to theguide rod 130 to avoid a risk of bending or breaking thesupport rod 160 due to accidental rotation of the slidingelement 140.FIG. 5 shows that theguide rod 130 has a non-cylindrical outer contour, for example, theguide rod 130 may have a triangular or other outer contours of a different shape. - Similarly, when the sliding
element 140 is pulled upward (the slidingelement 140 is moved toward the main body 120), the force is changed reversely. Thesupport legs 150 are moved toward thebase body 110 under this force, thereby moving the slidingelement 140 to fold thesupport legs 150. In the folded state, the lighting device has a small size and is convenient for carrying. - It should be noted that two ends (first connecting
end 161 and second connecting end 162) of thesupport rod 160 are not necessarily rotatably connected to thesupport leg 150 and thebase body 110, respectively. It can be understood that in other embodiments, the first connectingend 161 is rotatably connected to thesupport leg 150, and the second connectingend 162 is rotatably connected to themain body 120. In this case, in the folded state, thesupport rod 160 may not be hidden inside thesupport leg 150, thus affecting the appearance of thebase assembly 100. However, the function will not be affected. - In an embodiment, referring to
FIG. 6 , thebase assembly 100 further includes lockingstructure 170. The lockingstructure 170 is configured to lock thesupport legs 150 to limit the rotation of thesupport legs 150 when thesupport legs 150 are in the folded state. In this embodiment, referring toFIGS. 7 and 8 , the lockingstructure 170 includes first lockingelements 171 andsecond locking element 172. One of thefirst locking element 171 and thesecond locking element 172 is provided on thebase body 110, and the other is provided on thesupport leg 150. When thebase assembly 100 is in the folded state, thefirst locking elements 171 are engaged with thesecond locking element 172. Thefirst locking elements 171 and thesecond locking element 172 can be any structure that can be engaged with each other. For example, thefirst locking elements 171 and thesecond locking element 172 may be a groove locking structure, a magnetic suction structure, or a bonding structure. - In an embodiment,
FIG. 7 shows that thefirst locking elements 171 are respectively provided on thesupport legs 150 and thesecond locking element 172 is provided on thebase body 110. Thesecond locking element 172 includes lockingportions 173 andpressing portion 174 that are connected. The lockingportions 173 are exposed to a peripheral side of thebase body 110, and thepressing portion 174 is exposed to the bottom of thebase body 110. When thebase assembly 100 is in the folded state, the lockingportions 173 are respectively engaged with thefirst locking elements 171. Thus, thesupport legs 150 are limited to thebase body 110, and thesupport legs 150 cannot be easily separated from thebase body 110. When thesupport legs 150 need to be unfolded, a force is applied to thepressing portion 174 from the bottom of thebase body 110. Thepressing portion 174 drives the lockingportions 173 to disengage from thefirst locking elements 171 under the driving action of the external force. Thus, thefirst locking elements 171 are disengaged from the lockingportions 173. Thesupport legs 150 are unlocked, and thesupport legs 150 can be automatically unfolded under the drive of the slidingelement 140. It can be understood that in other embodiments, thesecond locking element 172 can also be provided on thesupport leg 150. In this case, thepressing portion 174 can be exposed outside thesupport leg 150, and thepressing portion 174 can drive the lockingportion 173 to be engaged or disengaged from thefirst locking element 171 through an intermediate transmission mechanism. The intermediate transmission mechanism can be a cam mechanism with a curved surface or a gear set. In the process of driving, the movement direction of thepressing section 174 may be the same as or different from that of the lockingportion 173. - Referring to
FIG. 7 , thesecond locking element 172 further includes restoringelement 175. The restoringelement 175 is provided between thebase body 110 and thepressing portion 174. When thepressing portion 174 drives the lockingportions 173 to disengage from thefirst locking elements 171, the restoringelement 175 accumulates a restoring force. When the external force driving thepressing portion 174 is released, the restoringelement 175 releases the restoring force accumulated to restore the lockingportions 173. For example, with the restoring force released by the restoringelement 175, the lockingportions 173 are engaged with thefirst locking elements 171 again after being restored. It should be noted thatFIG. 7 shows that the restoringelement 175 is a spring.FIG. 7 shows that the spring is compressed to accumulate a compression-restoring force in a process of force accumulation. However, the mounting position of the spring can also be changed according to user needs, such that the spring is extended to accumulate a tensile restoring force. It can be understood that in other embodiments, the restoringelement 175 may also be an elastic pad or an elastic ring. Alternatively, the restoringelement 175 may be a magnetic assembly. The magnetic assembly may include a first magnetic element and a second magnetic element. One of the first magnetic element and the second magnetic element is provided on thepressing portion 174, and the other is provided on thebase body 110. The first magnetic element and the second magnetic element are arranged opposite to each other and mutually exclusive. When thepressing portion 174 drives the lockingportions 173 to disengage from thefirst locking elements 171, the first magnetic element and the second magnetic element approach each other. The restoring force accumulated by the magnetic assembly is a magnetic repulsive force. - It should be noted that when the plurality of support ends 152 approach each other, the
first locking elements 171 contact the lockingportions 173. Thefirst locking elements 171 drive the lockingportions 173 to move against the restoring force of the restoringelement 175, such that the restoringelement 175 accumulates a restoring force. The first locking elements are engaged with the lockingportions 173 under the action of the restoring force. This can be achieved by setting the mounting positions of thefirst locking elements 171 and the lockingportions 173. In addition, a camber surface, an inclined surface, or a curved surface can be provided at a position where thefirst locking elements 171 contact the lockingportions 173 to realize a guiding effect, such that thefirst locking elements 171 and the lockingportions 173 move along corresponding guiding surfaces.FIG. 7 shows that each of thesupport rods 160 is provided withavoidance port 1601 through which thefirst locking elements 171 are engaged with thesecond locking element 172. - To clearly understand the movement details of the
second locking element 172 on thebase body 110, please refer toFIG. 7 . Thebase body 110 includes fixedbase 111,upper cover 112, andlower cover 113. In the extension direction of theguide rod 130, the fixedbase 111, theupper cover 112, and thelower cover 113 are axially connected sequentially. The fixedbase 111 is directly connected to theguide rod 130. Thebuffer pad 123 is sleeved on theguide rod 130 and attached to one end of the fixedbase 111 facing away from theupper cover 112. A side wall of the fixedbase 111 is further provided with rail grooves 1111 for guiding the movement of the lockingportions 173 respectively.Movable space 114 is formed between theupper cover 112 and thelower cover 113. Thepressing portion 174 is movably provided in themovable space 114. The lockingportions 173 pass through themovable space 114 and are respectively slidably provided in the rail grooves 1111. The restoringelement 175 is provided between thepressing portion 174 and the fixedbase 111. A peripheral side of themovable space 114 is further provided withrotating grooves 115 that are matched in number with thesupport rods 160. The second connecting ends 162 of thesupport rods 160 are respectively provided on therotating grooves 115 and are rotatable relative to thebase body 110. - In addition, it should be emphasized that the locking
structure 170 should only be understood as an embodiment of the present application, and it does not constitute a limitation on the lockingstructure 170 of the present application. In other embodiments, the lockingstructure 170 may also be directly connected to the plurality ofsupport legs 150 to realize the mutual limit of any twoadjacent support legs 150. For example, the lockingstructure 170 may be a latch cover. The latch cover can be covered on the bottom of thebase body 110 to limit the positions of the plurality of support ends 152 at the same time. Any lockingstructure 170 that can realize mutual limit of each twoadjacent support legs 150 should fall within the protection scope of the present disclosure. - In order to make the
support legs 150 automatically unfolded without manual control after being unlocked, in an embodiment, the lockingstructure 170 is also configured to unlock thesupport legs 150, such that the slidingelement 140 is automatically slidable from a side where themain body 120 is located to a side where thebase body 110 is located to unfold thesupport legs 150. - Referring to
FIGS. 7 and 8 , each of thesupport rods 160 is provided with first fixingportion 163, and each of thesupport legs 150 is provided withsecond fixing portion 154. Thebase assembly 100 further includestension spring 180. Two ends of thetension spring 180 are respectively connected to thefirst fixing portion 163 and thesecond fixing portion 154.FIG. 8 shows that thefirst fixing portion 163 is a hook provided on the first connectingend 161 of thesupport rod 160, and thesecond fixing portion 154 is a post fixed on therotating end 151 of thesupport leg 150. The hook and the post are only illustrative of this embodiment to facilitate understanding of this solution and should not constitute a specific limitation on the embodying form of thefirst fixing portion 163 and thesecond fixing portion 154. Thetension spring 180 is configured to accumulate an elastic force when thebase assembly 100 is in the folded state. Thetension spring 180 is also configured to release the elastic force to unfold thesupport leg 150 when thesupport leg 150 is unlocked. In the embodiment, thetension spring 180 can be understood to be located between the first connectingend 161 and therotating end 151. Based on the mounting position of thetension spring 180, in the folded state, thetension spring 180 is in an extended state and accumulates an elastic force. - When the
support legs 150 are in the folded state, the distance between thefirst fixing portion 163 and thesecond fixing portion 154 increases, and thetension spring 180 is deformed under tension. Thetension spring 180 generates a pulling force on thefirst fixing portion 163 and thesecond fixing portion 154. At this time, thesupport legs 150 receive an outward support force, causing thesupport legs 150 to be unfolded outward. However, the bottom of thesupport leg 150 is provided with thefirst locking element 171 or thesecond locking element 172, and thefirst locking element 171 is engaged with thesecond locking element 172, so thesupport leg 150 cannot be unfolded. Thus, thesupport leg 150 is kept in the folded state under the action of the lockingstructure 170. - Since the other end of the
second locking element 172 is provided with thepressing portion 174, when thepressing portion 174 is pressed by a force, thepressing portion 174 is displaced. The lockingportion 173 loses the locking effect with thefirst locking element 171. Thus, thesupport leg 150 is unfolded under the force of thesupport rod 160, such that thesupport leg 150 is in the unfolded state. - When the three
support legs 150 are in the unfolded state, the threesupport legs 150 can be manually combined to reset. During resetting, thefirst locking elements 171 contact the lockingportions 173 respectively. Under the action of the lockingportions 173, thepressing portion 174 is displaced, such that thesupport legs 150 are successfully and completely reset to the folded state. Thesecond locking element 172 resets under the action of theelastic element 175 and locks thefirst locking elements 171. - It should be noted that when the
tension spring 180 is located between the first connectingend 161 and therotating end 151, thesecond fixing portion 154 can be provided on thesupport leg 150 or the slidingelement 140. - The
tension spring 180 may also be located between the first connectingend 161 and thesupport end 152. When thetension spring 180 is located between the first connectingend 161 and thesupport end 152, thetension spring 180 is compressed in the folded state to accumulate an elastic force. Since thetension spring 180 has the elastic force to restore an original state, the tension spring can act on thefirst fixing portion 163 to make thefirst fixing portion 163 tend to rotate away from thesupport end 152, that is, tend to drive thesupport leg 150 to be unfolded. It should be noted that all the above embodiments of thetension spring 180 are also applicable to the case where thesupport rod 160 is provided between themain body 120 and thesupport leg 150. - In an embodiment, referring to
FIG. 9 , thelighting assembly 300 includesheat dissipator 310 andlighting element 320. Theheat dissipator 310 is connected to thefree end 220 of thetelescopic rod 200, and thelighting element 320 is provided in theheat dissipator 310. Thelighting element 320 is electrically connected to thecircuit board 100 d in thebase assembly 100. Specifically, thecircuit board 100 d may be connected to thelighting element 320 through a spring wire. The specific implementation of the spring wire can refer to the detailed introduction of the Chinese patent application CN202221356593.1, which will not be repeated herein. In this embodiment, thelighting element 320 is a light-emitting panel composed of a plurality of parallel and/or series LEDs. - The
heat dissipator 310 is provided withrotating groove 311. Thelighting element 320 is attached to theheat dissipator 310 to dissipate the heat of thelighting element 320 through theheat dissipator 310. That is, thelighting element 320 is in close contact with theheat dissipator 310 to effectively guide the working heat to theheat dissipator 310, thereby preventing thelighting element 320 from being damaged by high temperature. A side of theheat dissipator 310 away from therotating groove 311 is provided with mountinggroove 312, and thelighting element 320 is provided in the mountinggroove 312. Theheat dissipator 310 may be made of aluminum alloy. Theheat dissipator 310 may also be made of other materials with high heat dissipation performance, which is not limited herein. - To protect the
lighting element 320, thelighting assembly 300 further includes transparentprotective cover 330. The transparentprotective cover 330 is provided on the mountinggroove 312 to protect thelighting element 320. Illumination light of thelighting element 320 can directly penetrate the transparentprotective cover 330 without being obstructed. The design enables the illumination light to achieve a uniform scattering effect and improves the appearance effect of thelighting assembly 300. - The
lighting assembly 300 further includes heat dissipatorrear cover 340 covering therotating groove 311 and configured to transmit the working heat of thelighting element 320 to theheat dissipator 310 and the heat dissipatorrear cover 340. - Further, in order to realize the rotation of the
lighting assembly 300 relative to thefree end 220, thelighting assembly 300 further includesconnector 350. Theconnector 350 is provided with first connectingportion 351 and second connectingportion 352. The first connectingportion 351 is inserted at thefree end 220. Theconnector 350 is rotatable with the first connectingportion 351 as a rotation shaft, thereby realizing axial rotation. The second connectingportion 352 is provided in therotating groove 311. Thelighting assembly 300 is rotatable with the second connectingportion 352 as a rotation shaft, thereby realizing radial rotation. - Specifically, the
connector 350 is a T-shaped connector. The first connectingportion 351 of the T-shaped connector is inserted at thefree end 220, and the second connectingportion 352 of the T-shaped connector is provided in therotating groove 311. In this way, thelighting assembly 300 is rotatable axially and radially around thefree end 220. - It should be noted that the specific structure of the
lighting assembly 300 is based on the detailed introduction of Chinese patent application CN202221356593.1, which will not be repeated herein. In addition, the specific structure of thelighting assembly 300 is only an example of the present application and does not constitute a limitation on the present application. - In the embodiment of the present disclosure, the lighting device 1 is provided with the
second locking element 172 located on thebase body 110 and thefirst locking elements 171 located on thesupport legs 150. When thesupport legs 150 are in a folded state, thesecond locking element 172 is engaged with thefirst locking elements 171, such that thesupport legs 150 are in a locked state. That is, thesecond locking element 172 and thefirst locking elements 171 form a locking fit to prevent thesupport legs 150 from automatically being unfolded when being stored, thereby preventing the lighting device 1 from being automatically unfolded. The embodiment of the present disclosure solves the problem that thesupport legs 150 of a traditional lighting device 1 are easily damaged due to looseness in the folded state. In addition, the lockingstructure 170 of the embodiment of the present disclosure is configured to lock thesupport legs 150 in a folded state to limit the rotation of thesupport legs 150. The lockingstructure 170 can also unlock thesupport legs 150, such that the slidingelement 140 is automatically slidable from the side where themain body 120 is located to the side where thebase body 110 is located. Therefore, thesupport legs 150 can be automatically unfolded without manual operation after being unlocked, thereby facilitating user operation. - The present disclosure is described above with reference to several typical implementations. It should be understood that the terms used herein are intended for illustration, rather than limiting. The present disclosure may be specifically implemented in many forms without departing from the spirit or essence of the present disclosure. Therefore, it should be understood that the above embodiments are not limited to any of the above-mentioned details but should be broadly interpreted according to the spirit and scope defined by the appended claims. Therefore, the appended claims should cover any changes and modifications falling within the claims or the equivalent scope thereof.
