Technical Field

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

[0002] Nowadays, more and more people like outdoor activities such as camping and fishing. When doing outdoor activities, people usually carry some outdoor functional equipment accordingly. Lighting devices are one of them, which is particularly important for people to carry out outdoor activities at night.

[0003] Lighting devices used outdoors are usually divided into multiple component assembly structures or overall folding structures. In order to pursue convenience when carrying, the size of the lighting device with an overall folding structure is relatively smaller.

[0004] Moreover, a general foldable lighting device adopts a single light source, and the light source height is controlled by a telescopic rod and the components connected to the light source are rotated to control the light irradiation angle. The structure for adjusting the light source irradiation angle can only move the overall irradiation range of the light source to a certain position or expand the irradiation range of a certain area, but cannot realize the irradiation of two or more areas by the light source. The lighting of the lighting device cannot further take into account the use requirements of different application scenarios. Utility Model Content

[0008] Furthermore, the wall surfaces of both the supporting foot and the base on the shaft connection side are inclined surfaces. When the supporting foot rotates, the beveling effect of the two inclined surfaces enables it to fold flush with the base or swing obliquely away from the side wall of the base.

DETAILED DESCRIPTION

[0031] This embodiment discloses a foldable lighting device, such as Figures 1 to 3 As shown in combination, the lighting device includes a base 1, and supporting feet 2 are connected to both sides of the end of the base 1 through a rotating shaft. The supporting feet 2 use the ends of the supporting feet 2 connected to the axis of the base 1 as the rotation center to achieve folding flush with the base 1 or swinging in a direction away from the side wall of the base 1. A storage cavity 101 is provided in the middle of the base 1, and one end of the telescopic rod 3 in the storage cavity 101 is connected to the telescopic rod 3 through a rotating shaft, and the other end of the telescopic rod 3 is fixedly connected to a controller 4, and connecting seats 401 are connected to both ends and the middle of the controller 4. The connecting seats 401 at both ends of the controller 4 are arranged in a rotating shaft connection manner, and the connecting seat 401 in the middle of the controller 4 is arranged in a fixed connection manner, and the end of the connecting seat 401 away from the controller 4 is connected to a light source 5 through a rotating shaft.

[0032] It should be noted that the base 1 in the lighting device is provided with supporting feet 2 on both sides that can be turned out of the base 1. The supporting area of ​​the base 1 is increased by using the supporting feet 2 that are unfolded out of the base 1, so that the lighting device as a whole is supported after the telescopic rod 3 is extended, so that the area of ​​the bottom of the lighting device is sufficient to maintain the balance of the entire unfolded lighting device; when the supporting feet 2 are folded to both sides of the base 1, the supporting feet 2 and the base 1 as a whole remain flush and fit, so that the stability is higher when placed on the surface of other objects, and the lighting device is prevented from shifting under the action of external forces. Moreover, after the supporting feet 2 are folded and folded onto the base 1, the overall volume of the lighting device is small, so it is easy to carry; after the telescopic rod 3 in the lighting device is turned out and straightened in the storage cavity 101, it can play a role in adjusting the height of the light-emitting position of the light source 5, so as to meet the lighting needs of different heights. When the lighting device does not need to be folded, the rotating shaft connected to the bottom of the telescopic rod 3 can allow the telescopic rod 3 to be rotated and folded into the storage cavity 101, and the controller 4 will swing to the position outside the base 1 and remain flush with the base 1, so that the lighting device is smaller and easier to carry; the light source 5 of the lighting device is composed of a plurality of light sources 5 that can rotate at multiple angles, and the light sources 5 on both sides of the controller 4 can be rotated to different positions outside the controller 4 on both sides with the connection between the connecting seat 401 and the control shaft as the rotation center. In addition, the light source 5 can also swing up and down with the shaft connection between it and the connecting seat 401 as the rotation center, so that the light source 5 can adjust the lighting angle to different positions to meet the lighting needs of different application scenarios, and the user can adjust the brightness, color temperature and other working parameters of the light source 5 through the controller 4.

[0033] As a further preference of the above embodiment, Figure 4 and Figure 5 As shown in the figure, the wall surfaces of the support foot 2 and the base 1 on the shaft connection side are both inclined surfaces 6. When the support foot 2 rotates, the two inclined surfaces 6 are used to chamfer and fold flush with the base 1 or swing obliquely away from the side wall of the base 1. The bottom surface of the support foot 2 is not parallel to the bottom surface of the base 1 after the support foot 2 swings away from the base 1.

[0034] Among them, when the supporting foot 2 is rotated and unfolded, the beveling effect of the two inclined surfaces 6 causes the supporting foot 2 to be obliquely rotated outside the base 1, and the end of the supporting foot 2 away from the axis connected to the base 1 is the part where the supporting foot 2 contacts with other object surfaces. Since the supporting foot 2 is obliquely rotated, the bottom surface of the supporting foot 2 is no longer parallel to the bottom surface of the base 1, and the end of the base 1 away from the axis connected to the supporting foot 2 is the part where the base 1 contacts with other object surfaces, so that the bottom of the unfolded lighting device forms a supporting structure with the end of the base and the ends of the two supporting feet 2 as three supporting action points, thereby supporting the unfolded lighting device; due to the oblique rotation of the supporting foot 2 and the base 1 being away from the end connected to the axis of the supporting foot 2 as the part that contacts with other object surfaces, the base 1 is in an inclined state, so after the lighting device is unfolded, the inclination of the base 1 and the supporting foot 2 raises the horizontal height of the bottom of the lighting device, which plays a certain role in adjusting the overall height of the unfolded lighting device;

[0035] As a further preference of the above embodiment, Figure 2 As shown in the figure, the end surface of the base 1 close to the telescopic rod 3 for axial connection is provided with a first flange 102, and the surface of the supporting foot 2 is provided with a second flange 201. When the supporting foot 2 is in a folded state flush with the base 1, the first flange 102 and the second flange 201 form a semi-enclosed edge 7, and the edge 7 limits the light source 5 located near the outside of the base 1.

[0036] Among them, when the lighting device is folded, the controller 4 will swing to the position outside the base 1, and the light source 5 will be rotated by connecting the seat 401 and the shaft between the light source 5. After all the light sources 5 are arranged side by side, the light source 5 will swing to the space inside the surrounding edge 7. After all the light sources 5 are folded into the space inside the surrounding edge 7 flush with the base 1, the surrounding edge 7 can prevent the light source 5 from moving in the horizontal direction, which is conducive to maintaining the position of the light source 5 stable.

[0037] As a further preference of the above embodiment, Figures 6-8As shown in combination, a battery 8 is provided in the space of the support foot 2 away from the axial connection side of the base 1, a first matching hole 103 is provided at the end of the base 1 close to the axial connection side of the support foot 2, and a second matching hole 202 is provided at the end of the support foot 2 close to the axial connection side of the base 1, a hollow rotating shaft is passed through the first matching hole 103 and the second matching hole 202, and a nut 9 is matched to lock the end of the rotating shaft close to the second matching hole 202, a third matching hole 203 is provided on the wall of the support foot 2 opposite to the second matching hole 202, and the third matching hole 203 is matched with an end cover 10, and the side wall of the end cover 10 and the wall of the support foot 2 outside the end cover 10 are provided with a wire opening 11 connected to the internal space of the support foot 2 where the battery 8 is located, and a circuit board 12 is provided in the end of the base 1 close to the axial connection side of the support foot 2, and the circuit board 12 is provided with a charging socket 13 that passes through the wall of the base 1 and is electrically connected to the battery 8.

[0038] In this embodiment, a battery 8 is installed in the support foot 2 to power the controller 4, and the controller 4 is electrically connected to the light source 5 to provide power to the light source 5 to realize the lighting function. When the size of the base 1 is increased, the battery 8 can also be installed in the base 1, and the battery 8 is installed in the support foot 2. The internal space of the lighting device can be more reasonably utilized. Compared with the existing foldable lighting device, the volume of the base 1 of the lighting device after folding is smaller; a hollow rotating shaft is inserted into the first matching hole 103 and the second matching hole 202, which can not only realize the rotation of the support foot 2, but also can be used to rotate the support foot 2. The battery 8 is connected by leading out of the socket 11 to the hollow part of the shaft, and then introduced into the circuit board 12 in the end of the base 1 through the hollow part of the shaft, and connected to the charging socket 13 on the circuit board 12 through the line connected to the external power supply, so as to charge the battery 8; the setting of the third matching hole 203 can facilitate the operation of introducing the line connecting the battery 8 in the supporting foot 2 into the hollow part of the shaft. After completing the operation of introducing the battery 8 line into the hollow part of the shaft, the end cover 10 can be fitted into the third matching hole 203 to seal the third matching hole 203.

[0039] Preferably, Figure 8 and Fig. 9 As shown in the figure, the wall of the base 1 where the charging socket 13 is located is recessed to form a mating opening 104 for mating with the sealing block 14, the wall of the base 1 outside the charging socket 13 is provided with a mounting hole 105, and one end of the sealing block 14 is provided with a connecting column 141 connected to the mounting hole 105.

[0040] Among them, when there is no need to charge the battery 8, the sealing block 14 can be installed into the mating port 104, and the sealing block 14 can be used to seal the charging socket 13 to prevent foreign matter from entering the charging socket 13 and to prevent the charging socket 13 from being damaged by impact; when the sealing block 14 is mated to the mating port 104, the connecting column 141 can be inserted into the insertion hole 105 to improve the tightness of the sealing block 14 in the mating port 104, so as to prevent the sealing block 14 from falling off in the mating port 104.

[0041] Preferably, Figure 7 and Fig.10 As shown in the figure, the wall surfaces of the end cover 10 on both sides of the wire opening 11 are provided with wedge-shaped clamping blocks 15 , and the ends of the clamping blocks 15 are clamped in the wire opening 11 on the wall surface of the supporting foot 2 .

[0042] The end cover 10 is snapped into the third matching hole 203 through the snap-in block 15 , so as to fix the position of the end cover 10 and prevent the end cover 10 from being loosened in the third matching hole 203 .

[0043] Preferably, Fig.11 As shown, the bottom surface of the base 1 away from the axial connection side of the supporting foot 2 and the bottom surface of the supporting foot 2 away from the axial connection side of the base 1 are both provided with anti-slip protrusions 16, and the end cover 10 protrudes out of the end of the third matching hole 203 and is flush with the end surface of the anti-slip protrusion 16.

[0044] When the lighting device is in a folded state, the end cover 10 and the anti-slip protrusion 16 can be used as a supporting part at the bottom of the lighting device to prevent the surface of the base 1 and the surface of the supporting foot 2 from being scratched by friction with the surface of other objects.

[0045] Preferably, Figure 7 As shown, damping washers 17 which are compressed by the end of the rotating shaft and the nut 9 are disposed outside the ends of the first matching hole 103 and the second matching hole 202 .

[0046] The damping washer 17 can generate a certain damping force when the support leg 2 rotates, so that the position of the support leg 2 deployed is maintained, thereby preventing the support leg 2 from rotating without human operation.

[0047] As a further preference of the above embodiment, Fig.11 As shown, the outer wall of the base 1 outside the two sides of the storage cavity 101 is provided with a recessed portion 204, and the end wall of the support foot 2 away from the side connected to the axis of the base 1 is provided with a plurality of anti-slip grooves 205.

[0048] Among them, the setting of the recessed portion 204 can provide a position for the user's fingers to exert force, which is convenient for the user to flip the supporting foot 2 out from the two sides of the base 1 from the bottom end of the supporting foot 2; in addition, the setting of the anti-slip groove 205 can provide a position for the user's fingers to exert force, which is convenient for the user to flip the supporting foot 2 out from the two sides of the base 1 from the side wall of the supporting foot 2.

[0049] As a further preference of the above embodiment, Fig.11 As shown, the end of the base 1 close to the axial connection side of the support leg 2 is provided with a limiting portion 106 within the rotation range of the support leg 2.

[0050] Among them, through the setting of the limiting part 106, the rotation range of the supporting leg 2 can be limited, so that the position of the supporting leg 2 after being unfolded is maintained within a certain angle, avoiding that the rotation range of the supporting leg 2 is too large when unfolded, affecting the stability of the supporting structure formed at the bottom of the lighting device.

[0051] 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.
