Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, specifically to a foldable and retractable LED lamp. Background Technology

[0002] The basic structure of an LED light is a semiconductor material that emits light electronically. It is a solid-state semiconductor device that can directly convert electricity into light. In order to facilitate the storage of LED lights, a foldable LED light is required.

[0003] Patent CN208025214U discloses a conveniently foldable LED light, including an unfolding plate and a supporting base plate. The unfolding plate and the supporting base plate are movably connected on one side via a pivot. A storage slot is formed on the unfolding plate, and an LED light mounting bracket is movably disposed within the storage slot. The LED light mounting bracket is connected inside the storage slot via a folding device. The folding device includes a first support slider, a second support slider, a support rod, and an elastic telescopic cylinder. A displacement slide is installed within the storage slot, and the first support slider is movably disposed within the displacement slide. One side of the first support slider movably passes through the displacement slide and is movably disposed on the surface of the displacement slide. Two sets of second support sliders are fixedly welded to the side of the LED light mounting bracket near the storage slot. While this patent allows for the folding and storage of the LED light using the storage slot and folding device, it limits the user's ability to illuminate the LED light horizontally, making it difficult to adjust the illumination angle and thus limiting its usability.

[0004] Therefore, it is necessary to design a foldable and retractable LED light that is easy to adjust the illumination angle of the LED light. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies that can only illuminate LED lights horizontally and are not convenient for adjusting the illumination angle, the technical problem of the present invention is to provide a foldable and retractable LED light that is easy to adjust the illumination angle of the LED light.

[0006] The technical solution of the present invention is: a foldable and retractable LED lamp, comprising a first fixed frame, a first rotating frame, a sliding rod, a second rotating frame, a first connecting rod, and a lamp. The first rotating frame is rotatably connected to the first fixed frame, the sliding rod is slidably connected to the lower part of the first rotating frame, the second rotating frame is rotatably connected inside the sliding rod, the first connecting rod is connected to the second rotating frame, and a lamp for illumination is installed between the upper part of the second rotating frame and the first connecting rod. The lamp also includes a driving mechanism and a swinging mechanism. The bottom of the first rotating frame is provided with a driving mechanism for adjusting the illumination position of the lamp, and the front of the first rotating frame is provided with a swinging mechanism for adjusting the illumination angle of the lamp.

[0007] To further explain, the drive mechanism includes a support frame, a cylinder, a connecting plate, and a limiting ring. The support frame is connected to the bottom of the first rotating frame, and a cylinder is installed on the support frame. A connecting plate is connected to the telescopic rod of the cylinder. The upper part of the connecting plate is slidably connected to the sliding rod. Two limiting rings are connected to the front part of the sliding rod. The connecting plate is located between the two limiting rings, and the connecting plate can move to contact the limiting rings.

[0008] To further explain, the swing mechanism includes a threaded block, a limiting frame, and a first contact rod. The threaded block is connected to the second rotating frame and is located on one side of the first connecting rod. The lower part of the first rotating frame is connected to the limiting frame, and the first contact rod is connected to the limiting frame. The threaded block can slide and connect with the first contact rod, so that the threaded block drives the second rotating frame to rotate.

[0009] Further explanation: It also includes a fixing mechanism for fixing the connecting frame. The fixing mechanism includes a fixing block, a connecting frame, a locking rod, and a first elastic element. The fixing block is connected to the lower part of the first rotating frame. The fixing block is located on the right side of the limiting frame. The connecting frame is connected to the rear part of the sliding rod. The connecting frame has two slots. The locking rod for fixing the connecting frame is slidably connected to the fixing block. The locking rod engages with the slots. The first elastic element is sleeved on the locking rod. The two ends of the first elastic element are connected to the fixing block and the locking rod, respectively.

[0010] Further explanation: It also includes a support mechanism for supporting the lamp. The support mechanism includes a second fixed frame, a contact plate, and a second elastic element. The lower part of the first rotating frame is connected to the second fixed frame. The second fixed frame is located on the left side of the limiting frame. Two contact plates are rotatably connected to the second fixed frame. When the lamp rotates downward, it can contact the two contact plates, so that the two contact plates support the lamp. The lower part of each of the two contact plates is connected to the second fixed frame with a second elastic element.

[0011] Further explanation: It also includes an opening mechanism for moving the lever. The opening mechanism includes a second connecting rod, a contact frame, and a second contact rod. The second connecting rod is connected to the telescopic rod of the cylinder, and the contact frame is connected to the second connecting rod. The right side of the contact frame is a plane, and the lever is connected to the second contact rod. The contact frame can move to contact the second contact rod, causing the lever to move to the right.

[0012] To further explain, it also includes a rotating mechanism for rotating the first rotating frame. The rotating mechanism includes a third fixed frame, a motor, and a third connecting rod. The third fixed frame is connected to the left side of the first fixed frame. The motor is mounted on the third fixed frame. The output shaft of the motor is connected to the third connecting rod through a coupling. The third connecting rod is fixedly connected to the first rotating frame.

[0013] To further clarify, the lamp is rectangular in shape.

[0014] The beneficial effects of the present invention are as follows: 1. The operator can fold and store the lamp by rotating the lamp upward through the first rotating frame. By activating the cylinder, the sliding rod can be moved forward to adjust the lamp's illumination position. The second rotating frame can be rotated downward through the contact of the threaded block with the first contact rod to adjust the lamp's illumination angle.

[0015] 2. By engaging the locking rod with the locking slot, the connecting frame and sliding rod can be fixed, thereby achieving the purpose of fixing the extended lamp.

[0016] 3. By contacting the lamp with the contact plate, the lamp can be supported, thereby improving its stability during use.

[0017] 4. By starting the motor, the first rotating frame can be flipped upwards, thereby achieving the purpose of folding and storing the lamp.

[0018] 5. The lamps are rectangular in shape, which provides a wide illumination range and makes them easier for operators to use. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0029] Example 1

[0030] like Figure 1-4 As shown, a foldable and retractable LED light includes a first fixed frame 1, a first rotating frame 2, a sliding rod 3, a second rotating frame 4, a first connecting rod 5, a lamp 6, a drive mechanism 7, and a swing mechanism 8. The first fixed frame 1 is rotatably connected to the left and right sides of the first rotating frame 2. The sliding rod 3 is slidably connected to the lower part of the first rotating frame 2. The second rotating frame 4 is rotatably connected inside the sliding rod 3. The first connecting rod 5 is welded to the rear side of the second rotating frame 4. The lamp 6 for lighting is installed between the upper part of the second rotating frame 4 and the first connecting rod 5 by bolts. The drive mechanism 7 is provided at the bottom of the first rotating frame 2, and the swing mechanism 8 is provided at the front of the first rotating frame 2.

[0031] like Figure 1 and Figure 3 As shown, the drive mechanism 7 includes a support frame 71, a cylinder 72, a connecting plate 73, and a limiting ring 74. The support frame 71 is connected between the left and right sides of the bottom of the first rotating frame 2. The cylinder 72 is installed on the support frame 71 by bolts. The connecting plate 73 is fixed to the telescopic rod of the cylinder 72 by bolts. The upper part of the connecting plate 73 is slidably connected to the sliding rod 3. Two limiting rings 74 are welded to the front of the sliding rod 3. The connecting plate 73 is located between the two limiting rings 74. The connecting plate 73 can move to contact the limiting rings 74.

[0032] like Figure 1 and Figure 4As shown, the swing mechanism 8 includes a threaded block 81, a limiting frame 82, and a first contact rod 83. The threaded block 81 is fixed to the front side of the second rotating frame 4 by bolts. The limiting frame 82 is fixed to the lower front left side of the first rotating frame 2 by bolts. The first contact rod 83 is welded on the limiting frame 82. The threaded block 81 can slide and connect with the first contact rod 83, so that the threaded block 81 drives the second rotating frame 4 to rotate.

[0033] When the operator needs to use this device, the first fixing bracket 1 can be installed on the wall, and then the lamp 6 can be turned on to emit light. When the operator needs to adjust the illumination position and angle of the lamp 6, the cylinder 72 can be activated, causing the telescopic rod of the cylinder 72 to move the connecting plate 73 forward. When the connecting plate 73 contacts the front limiting ring 74, it can move the sliding rod 3, the second rotating bracket 4, the first connecting rod 5, and the lamp 6 forward. At the same time as the second rotating bracket 4 moves forward, it can move the threaded block 81, so that the threaded block 81 contacts the first contact rod 83. Turning the lamp 6 90 degrees to the left, once the lamp 6 reaches the predetermined position, cylinder 72 can be closed, stopping its operation. This allows the lamp 6, with its position and angle adjusted, to be easily used by the operator. When the lamp 6 needs to be folded for storage, it can be closed, and then the telescopic rod of cylinder 72 can be controlled to move the connecting plate 73 backward. When the connecting plate 73 contacts the rear limiting ring 74, it can move the sliding rod 3, the second rotating frame 4, the first connecting rod 5, the lamp 6, and the threaded block 81 backward to reset. When the threaded block 81 moves backward, it again contacts the first contact rod 8. Contact 3 causes the threaded block 81 to drive the second rotating frame 4, the first connecting rod 5, and the lamp 6 to rotate to the right and reset. Since the second rotating frame 4 and the threaded block 81 are moving backward at this time, the threaded block 81 will disengage from the first contact rod 83 as it moves backward. Then, the first rotating frame 2 is rotated upward to reset, causing the first rotating frame 2 to drive the lamp 6 upward via the sliding rod 3, the second rotating frame 4, and the first connecting rod 5. This allows the lamp 6 to be folded and stored. Conversely, when the operator needs to use the lamp 6, the first rotating frame 2 can be rotated downward to allow the lamp 6 to be folded and stored. 2. The lamp 6 is driven to rotate downwards and reset by sliding rod 3, second rotating frame 4 and first connecting rod 5. Then, the operation of starting cylinder 72 is repeated to use lamp 6. In this way, by starting cylinder 72, sliding rod 3 can be moved forward to adjust the illumination position of lamp 6. By the threaded block 81 contacting first contact rod 83, second rotating frame 4 can be rotated downwards to adjust the illumination angle of lamp 6. Because lamp 6 is rectangular, rectangular lamp 6 has a wide illumination range, which makes it convenient for operators to use lamp 6.

[0034] Example 2

[0035] like Figure 1 and Figure 5 As shown, based on embodiment 1, a fixing mechanism 9 is also included. The fixing mechanism 9 includes a fixing block 91, a connecting frame 92, a locking rod 94, and a first elastic element 95. The fixing block 91 is welded to the lower right front side of the first rotating frame 2. The connecting frame 92 is fixed between the front and rear sides of the rear part of the sliding rod 3 by bolts. The right side of the connecting frame 92 has two locking slots 93. The locking rod 94 for fixing the connecting frame 92 is slidably connected to the fixing block 91. The locking rod 94 is engaged with the locking slots 93. The first elastic element 95 is sleeved on the locking rod 94. The first elastic element 95 is a compression spring. The two ends of the first elastic element 95 are connected to the fixing block 91 and the locking rod 94, respectively.

[0036] like Figure 1 and Figure 7 As shown, it also includes an opening mechanism 11, which includes a second connecting rod 111, a contact frame 112, and a second contact rod 113. The second connecting rod 111 is fixed to the telescopic rod of the cylinder 72 by bolts. The contact frame 112 is welded to the rear of the second connecting rod 111. The right side of the contact frame 112 is a plane. The second contact rod 113 is connected to the rear right side of the locking rod 94. The contact frame 112 can move to contact the second contact rod 113, causing the locking rod 94 to move to the right.

[0037] As the telescopic rod of cylinder 72 moves forward, it drives the second connecting rod 111 and the contact frame 112 to move, causing the locking rod 94 to contact the contact frame 112 and move to the right. This compresses the first elastic element 95. As the locking rod 94 moves to the right, it disengages from the front locking groove 93, thus preventing the locking rod 94 from fixing the connecting frame 92 through the locking groove 93. Simultaneously, as the locking rod 94 disengages from the locking groove 93, the connecting plate 73 contacts the front limiting ring 74, causing the sliding rod 3 to drive the connecting frame 92 forward. As the locking rod 94 disengages from the locking groove 93, the second contact rod 113 contacts the plane of the contact frame 112. Simultaneously, as the sliding rod 3 reaches the predetermined position, the locking rod 94 aligns with the rear locking groove 93, and the second contact rod 113 disengages from the plane of the contact frame 112. This causes the first elastic element 95 to drive the locking rod 94 to move to the left and engage with the rear locking groove 93, thus allowing the locking rod 94 to engage with the connecting frame 92 and the sliding rod 3 through the locking groove 93. To fix the connection, as the telescopic rod of cylinder 72 moves backward, it drives the second connecting rod 111 and the contact frame 112 to move, causing the locking rod 94 to contact the contact frame 112 and move to the right again, compressing the first elastic element 95. As the locking rod 94 moves to the right, it disengages from the rear locking groove 93, thus preventing the locking rod 94 from fixing the connecting frame 92 through the locking groove 93. As the locking rod 94 disengages from the locking groove 93, the connecting plate 73 contacts the rear limiting ring 74, causing the sliding rod 3 to drive the connecting frame 92 to move backward and reset. As the sliding rod 3 resets, the locking rod 94 aligns with the front locking groove 93, and at this moment, the second contact rod 113 disengages from the plane of the contact frame 112, causing the first elastic element 95 to drive the locking rod 94 to move to the left and engage with the front locking groove 93. In this way, by engaging the locking rod 94 with the locking groove 93, the connecting frame 92 and the sliding rod 3 can be fixed, thereby achieving the purpose of fixing the extended lamp 6.

[0038] like Figure 1 and Figure 6 As shown, it also includes a support mechanism 10, which includes a second fixed frame 101, a contact plate 102, and a second elastic element 103. The second fixed frame 101 is fixed to the lower left side of the first rotating frame 2 by bolts. Two contact plates 102 are rotatably connected to the front side of the second fixed frame 101. The lamp 6 can rotate downward to contact the two contact plates 102, so that the two contact plates 102 support the lamp 6. The lower part of the two contact plates 102 is connected to the second fixed frame 101 by a second elastic element 103, which is a compression spring.

[0039] As the lamp 6 rotates downward, it comes into contact with the contact plate 102, causing the contact plate 102 to rotate downward and compress the second elastic element 103. When the lamp 6 is in contact with the contact plate 102, the contact plate 102 can support the lamp 6. As the lamp 6 rotates upward, it disengages from the contact plate 102, causing the second elastic element 103 to drive the contact plate 102 to rotate upward and reset. In this way, by contacting the lamp 6 with the contact plate 102, the lamp 6 can be supported, thereby improving the stability of the lamp 6 during use.

[0040] like Figure 1 and Figure 8 As shown, it also includes a rotating mechanism 12, which includes a third fixed frame 121, a motor 122 and a third connecting rod 123. The third fixed frame 121 is fixedly connected to the left side of the first fixed frame 1 by bolts. The motor 122 is installed on the third fixed frame 121 by bolts. The output shaft of the motor 122 is connected to the third connecting rod 123 through a coupling. The third connecting rod 123 is fixedly connected to the upper left side of the first rotating frame 2.

[0041] When the lamp 6 needs to be folded and stored, the motor 122 can be started, so that the output shaft of the motor 122 drives the third connecting rod 123 to rotate through the coupling. This causes the third connecting rod 123 to drive the first rotating frame 2 to flip upwards to store the lamp 6. Then the motor 122 can be turned off. When the lamp 6 needs to be used, the output shaft of the motor 122 can be controlled to drive the third connecting rod 123 to rotate in the opposite direction. This causes the third connecting rod 123 to drive the first rotating frame 2 to rotate downwards to reset. Then the motor 122 can be turned off. In this way, by starting the motor 122, the first rotating frame 2 can be flipped upwards, thereby achieving the purpose of folding and storing the lamp 6.

[0042] The technical principles of the embodiments of the present invention have been described above with reference to specific examples. These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.
