Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a stage light with smooth transmission. Background Technology

[0002] During stage lighting performances, adjustments to the size and shape of the projected light spot, the switching of the light projection distance and angle, and the adjustment of the clarity and uniformity of the light are made by the focusing lens assembly moving up and down along the direction of the light beam. In existing technologies, a motor is often used as the power source to drive the focusing lens assembly. When the motor drives the focusing lens assembly to move on the motor guide rod, the motor guide rod often shakes due to load-bearing stress or uneven installation. When it moves to the extreme positions at both ends of the motor rod, the shaking becomes more obvious due to the motor's own transmission clearance, wear, or control system problems. The motor shaking is transmitted to the focusing lens assembly, and this shaking phenomenon is reflected in the light spot, resulting in poor performance effects. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a stage light with smooth transmission, which can reduce the vibration caused by direct contact between the motor and the focusing lens assembly, and maintain smooth transmission when the motor drives the focusing lens assembly.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stage lamp with smooth transmission, including a lamp head, the lamp head including a light source and a focusing lens group located in the direction of the light beam emitted by the light source, the focusing lens group moving towards or away from the light source under the drive of a driving component, the driving component including a motor fixed relative to the light source and a driving rod connected to the focusing lens group, and a buffer component provided at the connection between the focusing lens group and the driving rod.

[0005] The focusing lens assembly is driven by a motor to move along the beam emission direction on the drive rod, thereby adjusting the light spot. By setting a buffer component to isolate and buffer the connection between the focusing lens assembly and the drive component, various degrees of vibration or abnormal noise caused by the motor's own transmission clearance, wear, or control system problems during the movement of the focusing lens assembly will not be directly transmitted to the focusing lens assembly. The buffer component can effectively buffer and reduce vibration and noise, so that the movement of the focusing lens assembly is more stable and quiet.

[0006] Furthermore, the drive rod does not rotate relative to the motor housing but only moves up and down. The drive rod drives the focusing lens assembly to move along the beam direction. The buffer assembly includes a transmission component fixedly connected to the drive rod, a connecting seat fixedly connected to the focusing lens assembly, and an elastic damping component. The elastic damping component is clamped between the transmission component and the connecting seat. The motor drives the drive rod to move up and down, thereby enabling the drive rod to drive the transmission component and the connecting seat to move, ultimately achieving the up and down movement of the focusing lens assembly. Furthermore, the elastic damping component consistently plays a role in isolation, buffering, and shock absorption during the up and down movement, preventing motor vibration from directly affecting the focusing lens assembly.

[0007] Furthermore, the connecting seat has a through hole at its center, and the elastic damping element has a central protrusion with an isolation step. The isolation step includes a central hole through which the drive rod passes. The isolation step is embedded in the through hole, and the outer surface of the isolation step is always in contact with the inner surface of the through hole. The isolation step effectively separates the drive rod from the connecting seat, preventing the vibration of the drive rod from directly affecting the transmission to the connecting seat.

[0008] Furthermore, it also includes a limiting cover. The transmission component has a limiting hole, and the drive rod passes through the limiting hole and is threadedly connected to the limiting cover to achieve connection with the transmission component. After the limiting cover and the drive rod are fixed by the threaded connection, it is ensured that the transmission component is always fixed on the drive rod.

[0009] Furthermore, the transmission component and the elastic damping component are integrally formed, reducing assembly errors and improving assembly accuracy.

[0010] Furthermore, the buffer assembly also includes a pressure plate connected to the connecting seat, and the transmission member is clamped between the pressure plate and the connecting seat.

[0011] Furthermore, the elastic damping element is clamped between the pressure plate and the transmission component, further enhancing the buffering effect of the focusing lens assembly.

[0012] Furthermore, the buffer assembly also includes a locking element, which locks the pressure plate to the connecting seat, preventing the pressure plate from falling off during operation.

[0013] Furthermore, the elastic damping element has at least two opposing limiting notches, and the connecting seat protrudes with a limiting post corresponding to the limiting notches. The locking element passes through the pressure plate and is threadedly connected to the limiting post. The limiting notch is simple to manufacture, and the limiting notch, in conjunction with the limiting post, can effectively prevent the elastic damping element from displacing in the direction perpendicular to the limiting post, thus avoiding an unsatisfactory buffering effect.

[0014] Furthermore, the drive rod only rotates relative to the motor housing without moving up or down. The drive rod is connected to the buffer assembly via a flange, with the inner side of the flange threadedly connected to the drive rod. The flange is fixedly connected to the buffer assembly. The motor drives the drive rod to rotate, causing the flange to move up and down on the drive rod. The flange is fixedly connected to the connecting seat, ultimately enabling the focusing lens assembly to move up and down. Furthermore, the elastic damping element consistently provides isolation, buffering, and shock absorption during the lifting process, preventing motor vibration from directly affecting the focusing lens assembly.

[0015] Furthermore, the focusing lens assembly includes a lens substrate with a recessed groove along the beam emission direction. The buffer assembly is embedded in the groove and threaded in place. Embedding the buffer assembly in the groove saves space occupied by the buffer assembly in the optical path direction, making better use of the internal space of the stage lamp.

[0023] The focusing lens assembly 100 is driven by the motor 210 to move along the beam emission direction on the drive rod 220, thereby adjusting the light spot. By setting a buffer assembly 300 to isolate and buffer the connection between the focusing lens assembly 100 and the drive assembly 200, various degrees of vibration or abnormal noise caused by the transmission clearance, wear of the motor 210 itself or problems with the control system during the movement of the focusing lens assembly 100 will not be directly transmitted to the focusing lens assembly 100. The buffer assembly 300 can effectively buffer and reduce vibration and noise, so that the movement of the focusing lens assembly 100 is more stable and quiet.

Furthermore, the elastic damping member 330 plays a role in isolation, buffering, and shock absorption throughout the up and down movement, preventing the vibration of the motor 210 from directly affecting the focusing lens assembly 100.

The isolation step 331 is embedded in the through hole 321, and the outer surface of the isolation step 331 is always in contact with the inner surface of the through hole 321. The isolation step 331 effectively separates the driving rod 220 from the connecting seat 320, preventing the vibration of the driving rod 220 from directly affecting the transmission to the connecting seat 320.

[0027] Preferably, the top end of the drive rod 220 does not exceed the connecting seat 320.

[0028] like Figures 1 to 3 In a preferred embodiment of this utility model, a limiting cover 340 is further included.

After the limiting cover 340 and the drive rod 220 are fixed by the threaded connection, it is ensured that the transmission member 310 is always fixed on the drive rod 220.

[0029] Preferably, the limiting cover 340 is a nut.

The limiting notch 333 has a simple manufacturing process, and the limiting notch 333, in conjunction with the limiting post 322, can effectively prevent the elastic damping member 330 from displacing in the direction perpendicular to the limiting post 322, thus avoiding an unsatisfactory buffering effect.

[0038] Preferably, the limiting notch 333 is C-shaped.

[0039] like Figures 1 to 3 In a preferred embodiment of this invention, the drive rod 220 rotates only relative to the housing of the motor 210 without moving up or down.

The flange is fixedly connected to the buffer assembly 300. The motor 210 drives the drive rod 220 to rotate, thereby causing the flange to move up and down on the drive rod 220. The flange is fixedly connected to the connecting seat 320, ultimately enabling the focusing lens assembly 100 to move up and down. Furthermore, the elastic damping element 330 plays a role in isolating, buffering, and shock absorption during the lifting process, preventing the vibration of the motor 210 from directly affecting the focusing lens assembly 100.
