[0001] The utility model relates to the technical field of lamps, in particular to a lamp holder structure of a foldable lamp. Background Art

[0002] Foldable lamps are a new type of special lamps that can be folded to make them convenient for people to carry. The lamp head structure of existing foldable lamps generally uses a single light source for lighting. The height of the light source is controlled by changing the length of the telescopic rod and the rotation of the parts connecting the light source to achieve the effect of controlling the irradiation position of the light source.

[0044] The controller 1 is composed of an upper shell 101, a lower shell 102 and a PCB 103. The PCB 103 is fixed in a shell 2 formed by the upper shell 101 and the lower shell 102. The shell 2 is provided with matching grooves 201 at both ends and the middle of the length direction.

[0045] The connector 3 is composed of a first rotating joint 301, a second rotating joint 302 and a first fixed seat 303, wherein one end of the first rotating joint 301 is fitted in the fitting groove 201, one end of the second rotating joint 302 is connected to the other end of the first rotating joint 301 by means of an axial connection, and the first fixed seat 303 is fitted to the other end of the second rotating joint 302;

[0047] A telescopic rod 5, one end of which is connected to the bottom end of the lower shell 102, and the other end of the telescopic rod 5 is connected to the base 6 of the foldable lamp;

[0048] Among them, the first rotating joint 301 connected to the middle part of the shell 2 is connected in a fixed connection manner, and the first rotating joints 301 at both ends of the shell 2 in the length direction rotate around the end part connected to the axis of the shell 2, and a first shaft column 304 is provided at the end of the second rotating joint 302, and a first matching hole 305 is provided in the middle part of the first fixing seat 303, and the first fixing seat 303 is matched with the outside of the first shaft column 304 through the first matching hole 305.

[0049] What needs to be explained in this embodiment is:

[0050] The input of control instructions can be realized through the buttons on the controller 1 , and the PCB 103 controls the working state of the light source 4 according to the input instructions, thereby adjusting the lighting effect of the light source 4 .

[0051] In addition, the first rotating joint in the connector 3 is used to realize the rotation of the light source 4 around the end of the controller 1, so that all the light sources 4 can be arranged side by side on the outside of the controller 1 or the light sources 4 can be arranged individually at different positions on the outside of the controller 1. At the same time, the second rotating joint 302 allows the light source 4 to rotate with a straight line parallel to the center line of the length direction of the controller 1 as the rotation center. In addition, through the rotation of the first fixed seat 303 with the first axis column 304 as the rotation center, the light source 4 can rotate with its own central axis as the rotation center. Under the rotation adjustment action of the connector 3, the variability of the lighting area position and the lighting coverage range of the lamp head is enhanced, so that the lighting effect of the lamp head of the folding lamp can meet the lighting needs of more application scenarios.

[0052] Moreover, the height position of the lamp head can be adjusted under the extension and retraction action of the telescopic rod 5, that is, the height position of the controller 1 is changed by the extension and retraction of the telescopic rod 5 to adjust the height position of the light source 4, thereby further expanding the lighting adjustment range of the lamp head; and the controller 1 can be moved to the outside of the side close to the folding lamp base 6 by folding the telescopic rod 5, thereby playing the function of folding and unfolding the lamp head in the folding lamp, so that the lamp head structure can be better matched to the use of the folding lamp; and in the use of the folding lamp, even if the lamp head is moved to a position close to the base 6, when it is not hindered by the base 6 and other objects in the scene, the light source 4 close to the base 6 can still swing to the position outside the controller 1 for lighting.

[0053] As a further preference of the above embodiment, Figures 9-11 As shown in combination, second shaft columns 306 are provided on both sides of the end portion where the first rotary joint 301 is axially connected to the shell 2, and matching columns 202 are provided on the ends in the length direction of the lower shell 102, one of the second shaft columns 306 is matched in the second matching hole 203 in the middle of the matching column 202, and the other second shaft column 306 is matched in the upper shell 101, and third shaft columns 307 are provided on both sides of the end of the first rotary joint 301 away from the second shaft column 306, and the end of the second rotary joint 302 away from the first shaft column 304 is "U"-shaped and has third matching holes 308 on both sides, and the end of the first rotary joint 301 with the third shaft column 307 is located near the end of the second rotary joint 302 away from the first shaft column 304, and the connection is achieved by the third shaft column 307 matching in the third matching hole 308.

[0054] Among them, through the cooperation of the three axial connection methods, namely, the cooperation between the second shaft column 306 and the matching column 202, the cooperation between the third shaft column 307 and the third matching hole 308, and the cooperation between the fixed seat and the first shaft column 304, the light source 4 can rotate in three different directions, so that the light source 4 can irradiate the external environment at different angles at any position outside the controller 1, and the adjustable range of the light source 4 is large.

[0055] Preferably, Fig. 9 and Fig.12 As shown in the figure, a damping pad 104 is provided in the end portion of the upper shell 101 in the length direction, a fourth matching hole 105 is provided in the middle of the damping pad 104 , and another second shaft column 306 is matched in the fourth matching hole 105 .

[0056] Among them, when the first rotating joint 301 rotates with the end of the shaft connected to the length direction of the controller 1 as the rotation center, since the second shaft column 306 is engaged in the fourth matching hole 105 in the middle of the damping pad 104, the damping pad 104 will generate a damping force on the side of the second shaft column 306, so as to position the first rotating joint 301 when the first rotating joint 301 is not subjected to a large external force, so that the position of the light source 4 rotated outside the controller 1 is more stable, thereby avoiding self-deviation of the light source 4.

[0057] Preferably, Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.14 As shown in combination, the interiors of the first rotary joint 301 and the second rotary joint 302 are both hollow, and the end of the first rotary joint 301 close to the second shaft column 306 is provided with a first opening 309 for connecting the internal space of the shell 2 with the internal space of the first rotary joint 301, the length of the third shaft column 307 in the axial direction is less than the depth of the third matching hole 308, and the middle part of the third shaft column 307 is provided with a first wire hole 310 for connecting to the internal space of the second rotary joint 302, and the middle part of the first shaft column 304 is provided with a second wire hole 311 for connecting to the internal space of the second rotary joint 302.

[0058] Among them, the first opening 309 can be used to introduce the circuit connected to PCB103 in the internal space of the shell 2 into the first rotary joint 301; because the length of the third shaft column 307 in the axial direction is less than the depth of the third matching hole 308, the position of the third matching hole 308 outside the third shaft column 307 forms a space that can introduce the circuit in the first rotary joint 301 into the second rotary joint 302, and the circuit in the first rotary joint 301 can be introduced into the second rotary joint 302 at this position through the first wire hole 310; and the circuit introduced into the second rotary joint 302 can be introduced into the light source 4 through the second wire hole 311 in the first shaft column 304, thereby realizing power supply to the light source 4 and command transmission and other operations.

[0059] Preferably, Fig.10 , Fig.12 , Fig.13 and Fig.14 As shown in combination, the second rotary joint 302 is composed of a connecting seat 312 and a connecting block 313, and limit blocks 314 are provided on both sides of the connecting seat 312, and a limit groove 315 is provided on one side of the connecting block 313. The connecting blocks 313 are connected to both sides of the connecting seat 312 through the cooperation between the limit groove 315 and the matching block, and the end of the connecting block 313 outside the third matching hole 308 and one end of the limit block 314 are both provided with a second opening 316. After the connecting block 313 and the limit block 314 are matched, the two second openings 316 are connected in the same straight line direction, and the end surface of the connecting seat 312 away from the first shaft column 304 is provided with a third opening 317 connected with the second opening 316 on the limit block 314, and a cover plate 318 is matched in the third opening 317, and both ends of the cover plate 318 extend into the second opening 316, and the limit block 314 and the connecting block 313 are both provided with a fifth matching hole 319.

[0060] When the second rotary joint 302 is assembled, the two connecting blocks 313 can be installed to both sides of the end of the first rotary joint 301 along the direction in which the third matching hole 308 and the third shaft column 307 axially match, and the line in the first rotary joint 301 is introduced into the internal space of the connecting block 313 outside the third matching hole 308, and then the connecting seat 312 is installed between the two connecting blocks 313 along the direction in which the limiting block 314 and the limiting groove 315 match. After the connecting seat 312 is installed between the two connecting blocks 313, the line in the internal space of the connecting block 313 outside the third matching hole 308 can be introduced into the second rotary joint 301. The setting of the third opening 317 in the joint 302 allows the operator to observe the line introduced into the second rotary joint 302, thereby facilitating the operator to introduce the line in the second rotary joint 302 into the first shaft column 304. After the internal line of the second rotary joint 302 is arranged, the third opening 317 can be sealed by the cover plate 318. When the internal line of the second rotary joint 302 is inspected, the cover plate 318 can also be removed from the third opening 317 to check the internal line of the second rotary joint 302; the fifth matching hole 319 can be passed through the connecting component to tightly connect the limit block 314 and the connecting block 313.

[0061] As a further preference of the above embodiment, Figure 8 , Fig.14 and Fig.15 As shown in combination, the light source 4 includes a lamp housing 401, a lamp board 402 with lamp beads and a diffuser cover 403. The outer walls on both sides of the first fixing seat 303 are provided with first snap-in grooves 404, and the inner walls on both sides of the lamp housing 401 are provided with first flanges 405 with hook-shaped cross-sections. One end of the lamp housing 401 is connected to the outer side of the first fixing seat 303 through the first flange 405 and the first snap-in groove 404, and the lamp board 402 is fixed to the inner wall of the lamp housing 401 away from the first flange 405. The walls on both sides of the diffuser cover 403 are provided with second flanges 406 with hook-shaped cross-sections.

[0062] Among them, after one end of the lamp housing 401 is connected to the first fixing seat 303 through the cooperation between the first flange 405 and the first snap-in groove 404, since the diffuser 403 is not installed, the outer side of the lamp housing 401 can provide a large enough space for the operator to connect the line led out of the first axis column 304 to the lamp board 402, which is convenient for the operator to operate when wiring the lamp board 402; after completing the wiring of the lamp board 402, the diffuser 403 is installed to the outer side of the lamp housing 401 along the direction of the cooperation between the second flange 406 and the first flange 405, so as to form an enclosure for the lamp board 402, and then the sealing end 407 is installed into the hole formed at the ends of the lamp housing 401 and the diffuser 403, and the assembly of the light source 4 is completed, and the operation is simple.

[0063] As a further preference of the above embodiment, Figures 16 to 19 As shown in combination, a storage groove 601 is provided in the middle of the base 6, and the two side walls of one end of the storage groove 601 are provided with a sixth matching hole 602, and a hollow second fixed seat 7 is provided in the storage groove 601 outside the sixth matching hole 602, and one end of the second fixed seat 7 is a connecting shaft 701 with a through hole, and the end of the connecting shaft 701 is fitted in the sixth matching hole 602 and communicated with the internal space of the base 6, and the end of the telescopic rod 5 away from the controller 1 is fitted in the second fixed seat 7, and the bottom end of the lower shell 102 is provided with a wire-through column 501, and the wire-through column 501 is fitted at the end of the telescopic rod 5 away from the connecting shaft 701 and communicated with the internal space of the telescopic rod 5.

[0064] Among them, the line connecting the power storage device in the base 6 can be introduced from the sixth matching hole 602 into the through hole of the connecting shaft 701, so that the line enters the second fixed seat 7. The telescopic rod 5 takes the connecting shaft 701 of the second fixed seat 7 as the rotation center, and the power transmission from the base 6 of the folding lamp to the lamp holder is realized through the hollow connecting shaft 701. It can also avoid the situation where the power transmission line is squeezed and broken when the telescopic rod 5 rotates; and the line entering the second fixed seat 7 will be led from the inside of the telescopic rod 5 to the wire post 501, and then enter the controller 1 through the wire post 501, so as to supply power to the lamp holder.

[0065] Preferably, Figures 16 to 19As shown in combination, a positioning seat 8 is provided on the outer sleeve of the end of the second fixing seat 7 close to the connecting shaft 701, a boss 603 is provided inside the receiving groove 601 outside the sixth matching hole 602, the top surface of the boss 603 is an inclined first guide surface 604, the top wall surface where one end of the boss 603 is connected to the first guide surface 604 is provided with a positioning groove 605, the end wall surface where the other end of the boss 603 is connected to the first guide surface 604 is a second guide surface 606, and protrusions 801 are provided on the left and right sides of one end of the positioning seat 8, and the side wall of the protrusion 801 close to the connecting shaft 701 is provided with an inclined third guide surface 802.

[0066] Among them, when the telescopic rod 5 is rotated from the storage groove 601 to the outside of the base 6 with the connecting shaft 701 of the second fixing seat 7 as the rotation center, the second guide surface 606 of the protrusion 801 will move in contact with the first guide surface 604, and the rotation trajectory of the positioning seat 8 will be guided by the tangential action of the two. At the same time, the end surface of the second fixing seat 7 located outside the second guide surface 606 will be in contact with the second guide surface 606. After the telescopic rod 5 continues to rotate out of the storage groove 601 until the telescopic rod 5 is vertical, the protrusion 801 enters the positioning groove 605 through the guidance of the first guide surface 604, and the protrusion 801 is limited by the positioning groove 605, so that the position of the positioning seat 8 is fixed, and then the position of the telescopic rod 5 is fixed. When the telescopic rod 5 is subjected to a certain degree of external force, it will not easily rotate, which is conducive to maintaining the shape of the lamp during use.

[0068] Among them, when installing the positioning seat 8 to the second fixing seat 7, since the end faces facing the third flange 702 and the clamping block 803 are both inclined surfaces, the positioning seat 8 can be inserted into the second fixing seat 7 under the tangent action of the end faces of the third flange 702 and the clamping block 803, which facilitates the insertion of the positioning seat 8 into the second fixing seat 7, and after crossing the clamping block 803, the other straight end face of the third flange 702 is clamped to achieve the effect of mutual clamping, thereby preventing the positioning seat 8 from easily detaching from the second fixing seat 7.

[0069] Preferably, Figures 16 to 19As shown in the figure, the end of the connecting shaft 701 is sleeved with a damping sleeve 10 , and the damping sleeve 10 is matched in the sixth matching hole 602 .

[0070] Among them, the damping sleeve 10 can generate a certain damping force when the second fixed seat 7 rotates with the connecting shaft 701 as the rotation center, thereby playing a certain position-maintaining role for the telescopic rod 5 during the rotation process, so that the telescopic rod 5 can be rotated to a certain position outside the base 6 and remain suspended, taking into account the different needs of the user when controlling the height position of the lamp head through the telescopic rod 5 to change the lighting position of the lamp head.

[0071] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
