Description

Technical Field

[0001] This utility model relates to the field of laser TV telescopic pan-tilt technology, and in particular to a thin electric telescopic platform. Background Technology

[0002] Laser TVs are fourth-generation televisions that use laser light sources and are equipped with professional anti-glare gain screens. They can receive broadcast programs and stream internet content. Many laser TV platforms can also achieve intelligent projection distance adjustment.

[0003] While existing laser TV platforms can achieve intelligent projection distance adjustment, they suffer from problems such as complex structure, large size, bulkiness, inconvenience in movement, and difficulty in telescopic assembly. As users increasingly demand thinner, more user-friendly, and more intelligent devices, existing products are gradually failing to meet these needs in terms of structure and function. Their production, assembly, and material costs are high, and they also have shortcomings in terms of limiting accuracy and operational comfort. For example, the traditional limiting methods used in some platforms may lead to inaccurate limiting, affecting the device's performance; the complex structure also increases the difficulty of installation and maintenance. Achieving a height of less than 30mm with existing pan-tilt units requires ultra-thin linear guides, which is extremely costly. Therefore, we propose an ultra-thin electrically telescopic platform.

[0004] Therefore, we propose a thin-film electric telescopic platform. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a thin-film electric telescopic platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A thin electric telescopic platform includes a telescopic platform, characterized in that: a motor pulley is provided below the telescopic platform, a synchronous belt is provided on the outer side of the motor pulley, a telescopic assembly is provided below the telescopic platform, and an upper cover plate is provided below the telescopic platform.

[0008] As a further improvement of this utility model: guide grooves are fixedly provided at both ends of the telescopic platform, and the motor pulley is fixedly connected to the transmission end of the drive motor.

[0009] As a further embodiment of this utility model: a transmission pulley is provided on the inner side of the synchronous belt away from the motor pulley, a control panel is fixedly provided below the upper cover plate, and a photoelectric switch is fixedly provided below the transmission pulley.

[0010] As a further embodiment of this utility model: a fixed bracket is fixedly installed below the telescopic platform, a reinforcing plate is fixedly installed on the inner side of the fixed bracket, and a motor fixing bracket is fixedly installed below the drive motor.

[0011] As a further embodiment of this utility model: a sheet metal base is fixedly installed below the second motor mounting bracket, and guide wheels are provided at both ends of the sheet metal base. As a further embodiment of this utility model: one side of the transmission pulley is fixedly connected to the lead screw, and a nut is provided to fix the sheet metal on the side of the lead screw away from the transmission pulley, and a lead screw nut is provided on the outer side of the lead screw.

[0012] Compared with the prior art, the present invention provides a thin electric telescopic platform, which has the following advantages:

[0013] 1. This utility model achieves an ultra-thin design of the pan-tilt unit without increasing costs by installing telescopic components and using guide wheels and guide grooves. The height of the laser TV placement surface is less than 30mm by using guide wheels, guide grooves and intermediate transmission. At the same time, the guide wheels are made of plastic-coated nylon material to reduce noise generation during operation.

[0014] 2. This utility model, while ensuring the original function, sets the two guide wheels in the guide wheel assembly to a structure with one high and one low. This ensures that errors generated during subsequent actual production and processing will not cause the gap between the guide wheel and the guide groove to be compressed, which would lead to the guide wheel getting stuck and unable to roll when carrying a laser TV. Due to the reduction in overall size and the innovative design of the two sides, the overall weight is greatly reduced, saving material costs and transportation costs.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example: A thin electric telescopic platform includes a telescopic platform 1, a motor pulley 2 is provided below the telescopic platform 1, a synchronous belt 3 is provided on the outer side of the motor pulley 2, a telescopic assembly is provided below the telescopic platform 1, and an upper cover plate 4 is provided below the telescopic platform 1.

[0023] like Figures 1-3As shown, guide grooves 5 are fixedly installed at both ends of the telescopic platform 1. The motor pulley 2 is fixedly connected to the transmission end of the drive motor 6. A transmission pulley 7 is installed on the inner side of the synchronous belt 3 away from the motor pulley 2. A control panel 8 is fixedly installed below the upper cover plate 4. A photoelectric switch 9 is fixedly installed below the transmission pulley 7. A first fixed bracket 10 is fixedly installed below the telescopic platform 1. A reinforcing plate 11 is fixedly installed on the inner side of the first fixed bracket 10. A second motor fixed bracket 12 is fixedly installed below the drive motor 6. A sheet metal base 13 is fixedly installed below the second motor fixed bracket 12. Guide wheels 14 are installed at both ends of the sheet metal base 13. One side of the transmission pulley 7 is fixedly connected to the lead screw 15. A guide wheel 14 is installed on the side of the lead screw 15 away from the transmission pulley 7. Sheet metal 16 is fixed with a nut, and a screw nut 17 is provided on the outside of the screw 15. When using a thin electric telescopic platform, the ultra-thin design of the gimbal is achieved without increasing costs through the set guide wheels 14 and guide grooves 5. The height of the laser TV placement surface is less than 30mm through the guide wheels 14, guide grooves 5 and intermediate transmission. At the same time, the guide wheels 14 are made of plastic-coated nylon to reduce noise generation during operation. While ensuring the original function, the two guide wheels 14 in the guide wheel group are set to a high and low structure to prevent the gap between the guide wheels 14 and the guide grooves 5 from being compressed due to errors in subsequent actual production and processing. This would prevent the guide wheels 14 from getting stuck and unable to roll when carrying the laser TV due to pressure.
