[0039] The main purpose of the utility model is to provide an expandable lamp head 100 to solve the problem that the lighting range of the lamp head of the existing floor lamp cannot be adjusted according to demand.

[0040] See also Figures 2 to 8 In one embodiment of the utility model, an expandable lamp head 100 includes a main lamp head 110, which is used to connect to an external structure; an auxiliary lamp head 120, which is spaced apart on one side of the main lamp head 110; and a telescopic component 130, which is connected between the main lamp head 110 and the auxiliary lamp head 120, and the telescopic component 130 is telescopically movable along the spacing direction between the main lamp head 110 and the auxiliary lamp head 120, and is used to make the auxiliary lamp head 120 move closer to or away from the main lamp head 110.

[0041] In the technical solution of the present utility model, the expandable lamp head is divided into a main lamp head 110 and a sub-lamp head 120, and the main lamp head 110 and the sub-lamp head 120 are connected by a telescopic assembly 130. The distance between the main lamp head 110 and the sub-lamp head 120 is changed by the telescopic assembly 130, thereby changing the range of the lamp head, so that the lighting range of the expandable lamp head 100 along the activity direction of the sub-lamp head can be adjusted. It can be understood that the technical solution can adjust the lighting range of the lamp head according to actual needs, and the needs of different lighting ranges can be met without replacing lamp heads of different specifications and sizes; at the same time, it also avoids making the lamp head too large to meet the needs of a large range of lighting, which affects the overall structural appearance of the floor lamp and causes inconvenience in transportation and packaging.

[0042] Specifically, in the present embodiment, the main lamp head 110 and the auxiliary lamp head 120 have the same appearance and are an overall rectangular parallelepiped structure. The main lamp head 110 includes a main lamp housing 111, an acrylic diffusion plate 112, an LED light-emitting panel 113 and a top cover 115; the auxiliary lamp head 120 includes an auxiliary lamp housing 121, an acrylic diffusion plate 112, an LED light-emitting panel 113 and a top cover 115; the main lamp housing 111 and the auxiliary lamp housing 121 are both hollow housings. A plurality of pressing sheets 114 are arranged around the LED light-emitting board 113, and fixing holes are opened on the pressing sheets 114. A light-emitting board installation groove 111a and a pressing sheet fixing groove 111b are opened on the bottom of the main lamp housing 111 and the auxiliary lamp housing 121. The upper parts of the main lamp housing 111 and the auxiliary lamp housing 121 are provided with a top cover fixing concave surface 111c.

The screws pass through the fixing holes on the pressing sheet 114 and are screwed into the pressing sheet fixing groove 111b to complete the fixation of the LED light-emitting board 113 and the acrylic diffusion plate 112. The top cover 115 is clamped on the top cover fixing concave surface 111c to complete the installation of the main lamp head 110 and the auxiliary lamp head 120. It is understandable that in some other embodiments, the main lamp head 110 and the auxiliary lamp head 120 can also be other shapes, such as sphere, rectangle, bar, other irregular polygons such as trapezoid, etc. The shapes of the main lamp head 110 and the auxiliary lamp head 120 can also be inconsistent, which depends on the actual situation and is not limited here.

[0043] Furthermore, in the present embodiment, the main lamp head 110 and the auxiliary lamp head 120 are connected by a telescopic assembly 130. The auxiliary lamp head 120 is arranged on one side in the width direction of the main lamp head 110. The light-emitting surfaces of the main lamp head 110 and the auxiliary lamp head 120 are on the same horizontal plane. The telescopic assembly 130 can be telescoped in the horizontal direction to make the auxiliary lamp head 120 move closer to or away from the main lamp head 110. Of course, the positional relationship between the main lamp head 110 and the auxiliary lamp head 120 and the telescopic direction of the telescopic assembly 130 are not limited to this. For example, in another embodiment, the light-emitting surfaces of the main lamp head 110 and the auxiliary lamp head 120 may not be on the same horizontal plane, that is, the light-emitting surface of the auxiliary lamp head 120 may be higher or lower than the light-emitting surface of the main lamp head 110; in another embodiment, the telescopic assembly 130 may not be telescopic and movable in the horizontal direction, that is, the telescopic assembly 130 may be telescopic and movable diagonally upward or downward of the main lamp head 110; in another embodiment, the auxiliary lamp head 120 may also be arranged on one side of the length direction of the main lamp head 110. It can be understood that according to the different shapes of the main lamp head 110, the auxiliary lamp head 120 can be arranged on any side of the main lamp head 110. The main lamp head 110 and the auxiliary lamp head 120 are connected by the telescopic assembly 130, so that the auxiliary lamp head 120 can be moved closer to or away from the main lamp head 110 through the telescopic movement of the telescopic assembly 130. The embodiments of the present invention are not limited thereto, and all of the above are within the protection scope of the present invention.

[0044] See also Figures 3 to 8 Furthermore, in one embodiment of the utility model, the telescopic assembly 130 includes: a sleeve 131, the sleeve 131 is provided on the main lamp head 110, and the sleeve 131 is extended along the spacing direction between the main lamp head 110 and the auxiliary lamp head 120; and an adjusting rod 132, one end of the adjusting rod 132 is inserted into the sleeve 131, and the other end is connected to the auxiliary lamp head 120, and the adjusting rod 132 can move along the length direction of the sleeve 131 to make the auxiliary lamp head 120 move closer to or away from the main lamp head 110.

[0045] Specifically, in this embodiment, the telescopic assembly 130 is in the form of a telescopic rod, which includes a sleeve 131 and an adjustment rod 132. The sleeve 131 is arranged on the main lamp head 110, and the sleeve 131 is convexly arranged on one side of the main lamp head 110 shell. The adjustment rod 132 is arranged on the auxiliary lamp head 120, and the adjustment rod 132 is arranged inside the auxiliary lamp housing 121. A connection hole 121a is opened on one side of the auxiliary lamp housing 121. One end of the adjustment rod 132 is arranged opposite to the connection hole 121a. The sleeve 131 passes through the connection hole 121a and is sleeved on the adjustment rod 132. When the telescopic rod is shortened to make the auxiliary lamp head 120 close to the main lamp head 110, the sleeve 131 can extend into the auxiliary lamp housing 121 along the adjustment rod 132, so that the auxiliary lamp head 120 can be closely attached to the main lamp head 110. Such a configuration can further save the occupied space of the lamp head, make full use of the lighting range, improve the lighting efficiency, and make the appearance of the lamp head more beautiful.

[0046] Of course, the arrangement of the sleeve 131 and the adjustment rod 132 can also be other ways. For example, in another embodiment, the sleeve 131 is arranged inside the main lamp housing 111, and a connecting hole 121a is opened on one side of the main lamp housing 111. One end of the sleeve 131 is arranged opposite to the connecting hole 121a. The adjustment rod 132 is protruded from one side of the auxiliary lamp housing 121. When the telescopic rod is shortened to make the auxiliary lamp head 120 close to the main lamp head 110, the adjustment rod 132 extends into the main lamp housing 111, so that the auxiliary lamp head 120 can be tightly attached to the main lamp head 110; in another embodiment, the sleeve 131 is protruded from one side of the main lamp housing 111, and the adjustment rod 132 is also protruded from one side of the auxiliary lamp housing 121. The sleeve 131 is sleeved on the adjustment rod 132. When the telescopic rod is shortened to make the auxiliary lamp head 120 close to the main lamp head 110, there is a certain spacing distance between the main lamp head 110 and the auxiliary lamp head 120. It can be understood that when the telescopic component 130 is in the form of a telescopic rod, the sleeve 131 of the telescopic rod can be set on the main lamp head 110 or on the auxiliary lamp head 120, and correspondingly, the adjustment rod 132 is set on the auxiliary lamp head 120 or on the main lamp head 110. The plug-in situation is also applicable to the above three situations, which will not be repeated here.

[0047] It should be noted that, in other embodiments, the telescopic component 130 may also adopt other forms, such as a slide, a slide rail and a slider, a telescopic cylinder, a screw rod, etc. The telescopic action may be completed manually or automatically, and the telescopic component 130 can be telescoped along the spacing direction of the main lamp head 110 and the auxiliary lamp head 120. The specific form may be determined according to actual conditions and is not limited here.

[0048] See also Figures 3 to 8 Furthermore, in one embodiment of the utility model, a driving assembly 140 is also included. The driving assembly 140 is disposed in the sleeve 131 , and the driving assembly 140 is transmission-connected to the adjustment rod 132 so that the adjustment rod 132 moves along the length direction of the sleeve 131 .

[0049] Specifically, in this embodiment, a driving assembly 140 is provided on the outside of the sleeve 131. Specifically, the driving assembly 140 includes a power source, a transmission unit and a control unit. The power source is provided on the sleeve 131. The transmission unit is connected to the adjustment rod 132. The power source can be a motor, a pneumatic pump, a pneumatic cylinder, etc., to provide power to the transmission unit, so that the transmission unit drives the adjustment rod 132 to move in the sleeve 131 along the length direction of the sleeve 131, and realizes the automatic control of the telescopic movement of the telescopic rod, so that the expandable lamp head 100 can be closed or unfolded; the control unit can be an actuator such as a control rod, a control knob, an electronic remote controller, etc., to realize local or remote control of the movement of the driving assembly 140. Such a configuration can further improve the convenience of use of the expandable lamp head 100 and realize the automation function.

[0050] See also Figures 5 to 8 Furthermore, in an embodiment of the present invention, the adjustment rod 132 includes a boss 1321 and a bottom plate 1322. The boss 1321 is convexly arranged on the surface of the bottom plate 1322. Along the length direction of the sleeve 131, the boss 1321 is movably inserted into the sleeve 131. The driving assembly 140 is in transmission connection with the bottom plate 1322. The driving assembly 140 drives the bottom plate 1322 to drive the boss 1321 to move along the length direction of the sleeve 131. Specifically, in this embodiment, the bottom plate 1322 is connected to the driving assembly 140 and the auxiliary lamp holder 120 in sequence. The driving assembly 140 drives the boss 1321 to move in the sleeve 131 by driving the bottom plate 1322, thereby controlling the auxiliary lamp holder 120 to approach or move away from the main lamp holder 110. By setting the adjustment rod 132 as a combination structure of the boss 1321 and the base plate 1322, on the one hand, the base plate 1322 can increase the contact area with the auxiliary lamp head 120, so that when the adjustment rod 132 drives the auxiliary lamp head 120 to move, the force area of ​​the auxiliary lamp head 120 is more uniform and the movement is more stable; on the other hand, the driving assembly 140 is connected to the base plate 1322 by transmission, so as to avoid the driving group directly applying driving force to the boss 1321, which causes shaking or instability during movement.

[0051] See also Figures 3 to 8 Furthermore, in one embodiment of the present invention, a limiting groove 131a is provided on the inner wall of the sleeve 131 along its length direction, and the boss 1321 can be movably engaged with the limiting groove 131a along the extending direction of the limiting groove 131a.

[0052] Specifically, in this embodiment, the boss 1321 of the adjustment rod 132 and the base plate 1322 are an integrally formed structure, and a limiting groove 131a whose shape matches the boss 1321 is opened on the sleeve 131. The limiting groove 131a is arranged through the length direction of the sleeve 131. The adjustment rod 132 slides in the limiting groove 131a through the boss 1321, so that the auxiliary lamp head 120 moves closer to or away from the main lamp head 110. Furthermore, the cross-section of the boss 1321 is in the shape of a lollipop, and the width of the grooves on both sides of the limiting groove 1131a extends horizontally for a certain distance toward the center of the limiting groove 1131a. The cross-section of the limiting groove 1131a is also in the shape of a lollipop. When the boss 1321 and the limiting groove 131a are movably matched, the boss 1321 can be stuck in the limiting groove 131a due to its large head and small body structure. Such a setting, on the one hand, prevents the boss 1321 from falling out of the limiting groove 131a, and on the other hand, plays a role of limiting and guiding the adjusting rod 132, so that the adjusting rod 132 can slide better in the sleeve 131.

[0053] See also Figures 3 to 8Furthermore, in one embodiment of the utility model, the driving assembly 140 includes a motor 141 and a gear 142. The motor 141 is arranged on the outside of the sleeve 131, and the gear 142 is connected to the output end of the motor 141; the side of the bottom plate 1322 close to the gear 142 is in the shape of a rack 1322a and meshes with the gear 142. The motor 141 drives the gear 142 to rotate to drive the bottom plate 1322 to move.

[0054] Specifically, in this embodiment, the driving assembly 140 includes a motor 141 and a gear 142. The motor 141 is installed on the outside of the sleeve 131 through the motor 141 bracket. One end of the output shaft of the motor 141 passes through the motor 141 bracket and is connected to the gear 142. The side of the bottom plate 1322 close to the gear 142 is set to be in the shape of a rack 1322a. The bottom plate 1322 is meshed with the gear 142 through the rack 1322a structure. The gear 142 is driven to rotate by the forward and reverse rotation of the motor 141, and then the bottom plate 1322 is driven to move back and forth along the extension direction of the limit groove 131a through the meshing transmission. The expandable lamp head 100 can be closed or unfolded by adopting a gear 142 transmission structure. On the one hand, the stability and accuracy of the telescopic structure can be improved. The gear 142 can provide precise speed ratio and position control, and can accurately control the lighting access of the lamp head. On the other hand, the combined structure of the gear 142 and the motor 141 is simple, and the two-way movement is completed by only one gear 142, which takes up little space and is easy to maintain. It can realize automatic control while reducing the maintenance cost of the lamp head.

[0055] See also Figures 2 to 5 Furthermore, in one embodiment of the utility model, the telescopic assembly 130 includes two auxiliary lamp heads 120 and two adjustment rods 132. Both ends of the sleeve 131 protrude from the main lamp head 110. The two auxiliary lamp heads 120 are respectively inserted into the two ends of the sleeve 131 through the two adjustment rods 132. The two auxiliary lamp heads 120 can move along the length direction of the sleeve 131 to move closer to or away from the main lamp head 110.

[0056] Specifically, in this embodiment, the sleeve 131 is arranged through the main lamp head 110, and the two ends of the sleeve 131 extend out of the main lamp housing 111. The sleeve 131 is provided with a limiting groove 131a along its length direction. There are two adjusting rods 132, one end of each adjusting rod 132 is inserted at the two ends of the sleeve 131, and the other ends of each adjusting rod 132 are connected to the auxiliary lamp heads 120, that is, an auxiliary lamp head 120 is arranged on both sides of the main lamp head 110 along its width direction. In this way, the lighting range of the expandable lamp head 100 can be further increased, and the interval between the two auxiliary lamp heads 120 and the main lamp head 110 can be adjusted separately to adapt to more occasions with different lighting ranges. Furthermore, the two ends of the sleeve 131 are respectively provided with a motor 141 and a gear 142 to control the two auxiliary lamp heads 120 to move closer to or away from the main lamp head 110. It should be noted that the above functions can be achieved by setting a sleeve 131 on the main lamp head 110, or by setting a sleeve 131 on both sides of the main lamp head 110. The position of the sleeve 131 on the main lamp head 110 depends on the actual situation. In the present embodiment, the sleeve 131 is preferably set in the middle of the main lamp head 110 so that the two auxiliary lamp heads 120 appear as a rectangle when they are close to or away from the main lamp head 110, thereby improving the overall stability of the lamp head. The embodiments of the utility model are not limited to this, and the above are all within the protection scope of the present utility model.

[0057] See also Figures 2 to 5 Furthermore, in one embodiment of the utility model, it also includes a guide tube 150 and a movable rod 151. The guide tube 150 and the telescopic component 130 are arranged at an interval with the main lamp head 110, and the extension direction of the guide tube 150 is consistent with the telescopic direction of the telescopic component 130; one end of the movable rod 151 is connected to the auxiliary lamp head 120, and the other end of the movable rod 151 can be movably inserted in the guide tube 150, and the movable rod 151 moves along the length direction of the guide tube 150 with the telescopic movement of the telescopic component 130.

[0058] Specifically, in this embodiment, the guide tube 150 and the movable rod 151 are both a telescopic rod structure. The main lamp head 110 is provided with a guide tube 150. The guide tube 150 has the same structure as the sleeve 131 and is spaced apart from the guide tube 150. The movable rod 151 has a basically identical structure to the adjustment rod 132. The movable rod 151 includes a boss 1321 and a guide base plate. The difference between the guide base plate and the base plate 1322 is that the guide base plate is not provided with a rack 1322a structure. This arrangement can save component processing costs and unify the overall structure. The boss 1321 of the movable rod 151 is slidably matched with the limit groove 131a of the guide tube 150, so that the movable rod 151 can move along the length direction of the guide tube 150; when the driving assembly 140 drives or manually drives the adjusting rod 132 to move in the sleeve 131, so that the auxiliary lamp head 120 moves closer to or away from the main lamp head 110, the movable rod 151 moves in the guide tube 150 along the same moving direction; by setting the guide tube 150 and the movable rod 151, a structure similar to multiple telescopic rods driving the auxiliary lamp head 120 is formed in cooperation with the sleeve 131 and the adjusting rod 132 structure, which increases the stability of the adjusting rod 132 when driving the auxiliary lamp head 120 to move, provides a guiding effect, and makes the overall structure of the expandable lamp head 100 more stable. Furthermore, two guide tubes 150 and movable rods 151 are provided. The two guide tubes 150 are spaced apart on both sides of the sleeve 131 along the length direction of the main lamp holder 110. One end of the two movable rods 151 is inserted into the corresponding guide tubes 150, and the other end of the two movable rods 151 is connected to the auxiliary lamp holder 120. Further, when an auxiliary lamp holder 120 is connected to each side of the main lamp holder 110, the guide tube 150 and the sleeve 131 adopt the same structure and arrangement, that is, both ends of the guide tube 150 extend out of the main lamp holder 110, and movable rods 151 are inserted into both ends of the guide tube 150. The movable principle and the effect produced are consistent with the above, and will not be repeated here.
