DETAILED DESCRIPTION
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings. The description of the foregoing embodiments should be able to enable a person of ordinary skill in the art to fully understand the operation, use, and effects of the present invention. The embodiments, however, are only some preferred ones of the present invention and are not intended to be restrictive of the scope of the present invention. All simple equivalent changes and modifications made accordingly to the appended claims and the present specification should fall within the scope of the present invention.
As shown in FIG. 1 through FIG. 6, the present invention discloses a 3D swing simulation electronic candle lamp. The 3D swing simulation electronic candle lamp comprises a retaining device and a swing device. The swing device is installed on the retaining device. A fake flame 1 is provided and retained on the swing device, enabling the fake flame 1 to swing freely in an upright direction along with the swing device so as to imitate the swing effect of a real flame.
Based on the forgoing technique, the swing device comprises a power mechanism, a transmission mechanism, and a swing assembly. The fake flame 1 is fixedly connected with the swing assembly. The power mechanism drives the swing assembly through the transmission mechanism.
Based on the forgoing technique, the present invention further comprises a battery, a controller, and a luminous member 2. The fake flame 1 has a first accommodation room therein. The luminous member 2 is disposed in the first accommodation room. The luminous member 2 is able to shine after electrified. The battery, the controller, and the luminous member 2 are electrically connected in sequence. The fake flame 1 is made of a light-pervious material, such that the light of the luminous member 2 penetrates through the fake flame 1 to be seen. This ensures that the fake flame 1 can be seen in a bad illumination condition. The color of the light from the luminous member 2 can be changed. The luminous member 2 is selected from an LED light. The controller is electrically connected with a control end of the power mechanism. The power output mode of the power mechanism is controlled by the controller. For example, if the power is outputted continuously, the fake flame 1 will swing at the same breadth; if the power is outputted intermittently, the fake flame 1 will swing at different breadths.
The controller comprises a main control PCB board 14 installed inside a cylinder 12 and a switch 15 installed outside the cylinder 12. The switch 15 is also installed on the main control PCB board 14. The switch 15 is adapted to control the power supply of the power supply circuit.
Based on the forgoing technique, the retaining device comprises a support block 4 fixed on an upper end of the retaining device. An upper end of the support block 4 is a spherical point. The spherical point of the upper end of the support block 4 functions as a swing fulcrum of the swing device. The swing device comprises a swing frame 3. The fake flame 1 is retained at an upper end of the swing frame 3. The swing frame 3 is provided with a curved recess to mate with the upper end of the support block 4. The spherical point of the support block 4 is in corporation with the curved recess, enabling the swing frame 3 to swing freely relative to the spherical point (as shown in the direction of the arrows A-A of FIG. 3). Because the swing frame 3 can swing freely relative to the spherical point, the fake flame 1 can swing freely along with the swing frame 3 (as shown in the direction of the arrows B-B of FIG. 3) to provide a realistic effect like a real candle to burn and swing.
Based on the forgoing technique, the bottom of the swing frame 3 is provided with a first magnetic member 6. The power mechanism is a drive motor 8 which has the control end electrically connected with the controller. The transmission mechanism comprises a rotary pendant 5 which is fixedly connected with a power output shaft of the drive motor 8. One end of the rotary pendant 5 extends toward the first magnet member 6. An extension end of the rotary pendant 5 is provided with a second magnet member 7. The drive motor 8 brings the rotary pendant 5 to turn. Along with turning of the rotary pendant 5, the first magnet member 6 and the second magnet member 7 are to approach or away from each other, such that the second magnet member 7 is changed by the attraction force (the magnetic poles of the face-to-face surfaces of the first magnet member 6 and the second magnet member 7 are different) or the repulsion force (the magnetic poles of the face-to-face surfaces of the first magnet member 6 and the second magnet member 7 are the same) of the first magnet member 6. The second magnet member 7 subject to the force of the first magnet member 6 brings the swing frame 3 to swing. Through the magnets, the swing frame 3 generates a corresponding swing along with the turning of the rotary pendant 5.
The shape of the swing frame 3 is a frame to decrease its weight. Two sides of the swing frame 3 are symmetrically disposed at two sides of the central symmetrical axle of the swing for the swing frame 3 to balance and return. The rotary pendant 5 is located in the swing frame 3. The central symmetrical axle of the swing frame 3 penetrates through the extension end of the rotary pendant 5. This ensures that when the extension end of the rotary pendant 5 is turned to the closest distance relative to the second magnet member 7, the action force of the two magnet members is the biggest.
The retaining device further comprises a casing 9. A support seat 11 is fixedly connected to an upper end of the cylinder 12. The support seat 11 extends upward out of the upper end of the cylinder 12 and is fixedly connected with the casing 9. The drive motor 8 and the rotary pendant 5 are installed in the casing 9.
The cylinder 12 has an interior space installed with a positive and negative battery plate 18, a battery compartment 16, and a battery positive and negative PCB board 13 which are arranged from bottom to top.

Terminals on the positive and negative battery plate 18 and terminals on the battery positive and negative PCB board 13 are respectively inserted through the conductive through holes to form a power supply circuit. The base is provided with a battery hole for installation of a battery. The battery hole is provided with a battery lid 19. The battery is mounted in the battery compartment 16 to prevent the battery from shaking, enabling the power supply circuit to supply stable power. The battery lid 19 is installed in the battery hole in a snap-in manner for convenient assembly and disassembly.
The luminous member 2 is electrically connected with the main control PCB board 14 through gold-plated fiber wires or silver-plated fiber wires.
The present invention further comprises a cover 20. The cover 20 is adapted to cover the retaining device and the swing device. An upper end of the cover 20 is provided with a through hole. The fake flame passes through the through hole. The cover 20 is made of solid wax or a plastic material.
