Description

Technical Field

[0001] The present application relates to the field of rotating seats, and in particular to an electrically rotatable base. Background Art

[0002] Patent publication number CN102418868A discloses a lighting lamp. Specifically, it comprises a reflector, a light source, and a lamp holder. The lamp holder comprises an upper lamp holder and a lower lamp holder. The reflector and light source are fixedly mounted on the upper lamp holder. A lifting mechanism and a rotating mechanism are provided between the upper and lower lamp holders. A connector connects the rotating mechanism to the upper lamp holder. The upper lamp holder is driven by the fixing frame through the positioning piece to rotate the lead body in the top ball. Since a rotating shaft is provided between the lead body and the inner cavity of the top ball, a connecting spring block is provided on the outside of the lead body and is movably docked with the annular conductive block provided on the side wall of the inner cavity. The movable docking is that the connecting spring block is tightly attached to the annular conductive block and can rotate around the annular conductive block to achieve the conductive effect during rotation, and the connecting ball provided at the center position of the lead body is movably docked with the conductive block provided at the center position of the inner cavity. The rotating axes of the lead body and the top ball are concentric axes, so that when the upper lamp holder and the lead body rotate 360 ​​degrees, the top ball and the lower lamp holder are fixed, and the connecting spring block and the connecting ball of the lead body can be docked with the annular conductive block and the conductive block in the inner cavity of the top ball, and conduct electricity to the light source, so as to achieve continuous rotation and swing without causing undesirable phenomena such as wire entanglement or winding.

[0003] As can be seen from the above, in order to avoid the problem of wire entanglement or winding, this patent designs a rotating device and a power connection device. The lamp holder is driven to rotate by a motor, so that the reflective bowl rotates with the upper lamp holder, and the power cord therein does not rotate, thereby ensuring normal power supply while avoiding wire entanglement or winding; however, in addition to the load (lights, advertising boxes, etc.), there are obviously too many components that need to be driven by the motor, and the weight is too large, which puts a heavy burden on the motor.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figure 1-Figure 3As shown, the present application relates to an electrically powered rotating base, which includes: a fixed chassis 1, a drive motor 2 fixed below the fixed chassis 1, and a carbon brush assembly 3 fixed above the fixed chassis 1; a rotating shaft 4 connected to the drive motor 2; a slip ring 5 sleeved on the outer side of the rotating shaft 4, which is located above the fixed chassis 1; one side of the slip ring 5 contacts the carbon brush assembly 3 to form a conductive path, and the end of the slip ring 5 forms an outlet terminal 18; the end of the wire of the carbon brush assembly 3 forms an inlet terminal. The fixed chassis 1 serves as the installation base for the drive motor 2, ensuring the stability of the motor fixation; the drive motor 2 is used to drive the rotating shaft 4 connected to it to rotate; the rotating shaft 4 is used to connect to external devices such as advertising boxes and lamps, so that when the drive motor 2 rotates, it can drive the rotation of these external devices; the slip ring 5 is used to transmit the electrical energy connected to the outlet terminal 18 to the carbon brush assembly 3, and then the carbon brush assembly 3 outputs the electrical energy to the external device connected to the outlet terminal 18 for power supply. It should be understood that during the rotation of the motor, the shaft 4 is driven to rotate, and the collector ring 5 on the shaft 4 also rotates accordingly, while the motor itself, the fixed chassis 1, the carbon brush assembly 3 and other components do not rotate accordingly. This ensures that in addition to external equipment such as lights and advertising boxes that need to be connected, the motor only needs to drive the lighter shaft 4 and collector ring 5, which greatly reduces the burden on the motor. At the same time, since the collector ring 5 will be driven to rotate by the motor, it ensures that the wires will not be entangled when the power is normally on.

[0031] From the above description, it can be seen that this application achieves the following technical effects:

[0033] Preferably, the rotating shaft 4 is a hollow circular tube with a pair of waist-shaped holes 6 formed therein. The wires of the slip ring 5 pass through the pair of waist-shaped holes 6, enter the hollow circular tube, and emerge from the top of the hollow circular tube. The combination of the waist-shaped holes 6 and the hollow circular tube allows the wires of the slip ring 5 to be routed within the hollow tube, thereby ensuring structural stability and compactness and avoiding cluttered wiring. Furthermore, the outer diameter of the main portion of the rotating shaft 4 is larger than the inner diameter of the bearing 8. The portion of the rotating shaft 4 inserted into the bearing 8 is tightly matched to the inner ring of the bearing 8 and is smaller than the outer diameter of the main portion of the rotating shaft 4.

This design ensures that no friction will be generated between them during normal rotation. However, in extreme cases, such as when the bearing 8 is damaged, the middle platform of the boss and the end face of the outer ring of the bearing 8 can restrain each other, effectively preventing the potential risks caused by the withdrawal of the rotating shaft 4; the outer ring of the boss is connected to the inside of the cylindrical fixed base and leaves a safety distance, ensuring that it coincides with the outer ring of the bearing 8 in the axial direction and plays a safety role while effectively avoiding friction.The limiting plate 9 at the bottom is a circular three-layer overlapping boss structure, and the connecting vertical surface of the second-layer boss and the third-layer boss is a threaded structure, which is used to be tightly connected to the bottom inner wall of the rotating shaft 4; the table surface of the second-layer boss is tightly matched with the end face of the inner ring of the bearing 8, which plays a role in fixing the bearing 8; the first-layer platform of the boss and the end face of the outer ring of the bearing 8 coincide in the axial direction, but the two are not directly connected.

[0036] Preferably, a waterproof cover 14 is also provided on the top of the fixing seat 7; the waterproof cover 14 is in the shape of a cylindrical bowl, with a through hole 10 in the center, the size of the through hole 10 is closely matched with the central axis and is sleeved on the central axis, and the contact part between the through hole 10 and the central axis is fixed with a waterproof structural adhesive and meets the requirements of fixation and waterproofing at the same time; the inner side of the waterproof cover 14 is connected to the bottom end face of the boss of the top limit plate 9; the bowl-shaped edge of the waterproof cover 14 surrounds and separates the bottom profile of the cylindrical fixing base, which ensures the waterproof requirement without causing friction or hindrance to the rotation.

[0037] Preferably, an insulating gasket 15 is provided between the slip ring 5 and the bottom bearing 8, and the insulating gasket 15 is sleeved on the rotating shaft 4; one end of the slip ring 5 is isolated from the bottom bearing 8 by the insulating gasket 15 to achieve an insulation effect.

[0039] Preferably, a protective cover 17 is also provided on the outside of the fixed chassis 1 and the rotating shaft 4; the protective cover 17 provides protection for the fixed seat 7, the drive motor 2, the collector ring 5 and other components. In this embodiment, preferably, the bottom of the circular protective cover 17 is cylindrical, and is matched and fixedly connected to the fixed chassis 1 through the decorative cover fixing angle code, which not only provides protection but also increases the aesthetics. Furthermore, the middle part of the circular protective cover 17 gradually shrinks to the top, forming a small circular platform structure with a circular hole. This design not only enhances the structural strength of the protective cover 17, but also maintains the overall aesthetics. The size of the circular hole in the center of the small circular platform at the top is designed to just allow the central axis to pass through, which not only ensures that the rotation of the central axis is not hindered, but also effectively protects the upper part of the device through the protective cover 17.
