Abstract
Description
Technical Field
[0001] This utility model relates to the field of potentiometers, and in particular to a potentiometer for controlling the angle of a ceiling-mounted screen. Background Technology
[0002] A ceiling-mounted screen is a display device installed on the roof of a car, providing audio-visual entertainment services for passengers. Ceiling-mounted screens are often rotatably installed in the vehicle body. When in use or stored, they are rotated to switch states. During the switching process, it is often necessary to identify the angle between the ceiling-mounted screen and the vehicle body. Existing technology mainly uses magnetic encoders to identify the angle by recognizing the angle of the magnet's rotation. However, existing technology requires the installation of positioning magnets and encoders, which results in high costs and relatively complex structures. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a potentiometer for ceiling-mounted screen angle control that can be used in conjunction with the ceiling-mounted screen for angle adjustment, simplifies the overall structure, and reduces costs.
[0004] To achieve the above objectives, this utility model provides a potentiometer for controlling the angle of a ceiling-mounted screen, comprising a potentiometer body, a housing, a top cover, and an adjusting component. The potentiometer body is located at the lower end of the housing, and the housing has an adjusting hole corresponding to the potentiometer body. One end of the top cover is rotatably connected to the housing, and a fixing plate is provided at the other end. The fixing plate is used to connect to the ceiling-mounted screen. The adjusting component is located between the housing and the top cover. One end of the adjusting component is inserted into the top cover and forms an anti-rotation engagement with it, while the other end of the adjusting component extends into the adjusting hole and forms a transmission engagement with the potentiometer body.
[0005] The advantages of the above technical solution are as follows: The potentiometer body, housing, top cover, and adjusting component are configured. The potentiometer body is positioned at the lower end of the housing, with an adjusting hole on the housing. The top cover is rotatably connected to the housing, with a fixing plate at its other end connected to the ceiling screen. The adjusting component is positioned between the housing components, allowing one end to rotate with the top cover, while the other end extends into the adjusting hole to engage with the potentiometer. During operation, the fixing plate connected to the ceiling screen causes the top cover to rotate with the ceiling screen, which in turn drives the adjusting component to rotate. Rotating the adjusting component extending into the adjusting hole adjusts the potentiometer body, causing the resistance within the potentiometer body to change with the rotation of the ceiling screen, thus revealing the angle change of the ceiling screen. This design is lower in cost and simpler in structure.
[0006] The present invention can be further configured as follows: the adjusting member includes a reinforcing part and an extending part; the adjusting hole is located at the position corresponding to the rotation axis of the adjusting member; the fixing plate and the extending part are both located at positions offset from the rotation axis of the adjusting member; and the extending part is bent and extended into the adjusting hole to form a transmission fit between the adjusting member and the potentiometer body; the reinforcing part is located at the root of the extending part.
[0007] By further refining the design, a reinforcing section and an extension section are added to the adjusting component. The fixing plate and the extension section are both positioned off-axis from the rotating axis of the adjusting component. This is because the fixing plate needs to be installed off-axis from the ceiling screen's rotating axis, and this setting allows for better alignment. The adjusting hole is located on the axis of the adjusting component, and the extension section bends and extends to the adjusting hole. This allows the change in the potentiometer's resistance to better adapt to the rotation of the ceiling screen. Finally, a reinforcing section is added at the root of the extension section to ensure its strength and the product's lifespan.
[0008] The present invention can be further configured such that: the upper cover includes a slot, the adjusting member includes an insert for engaging with the slot, the insert is semi-cylindrical, and the outer wall of the insert is provided with an arc-shaped rib that can abut against the inner wall of the slot.
[0009] By further designing the upper cover, a slot is provided on the upper cover, and an insert is provided on the adjusting part. The slot and the insert are used to assemble the two parts. The arc-shaped ribs on the insert are provided to ensure the strength of the insert and the connection strength between the two parts.
[0010] The present invention can be further configured such that: the upper cover includes an abutting part, the abutting part is provided with a plurality of protrusions, and the adjusting member is provided with a plurality of radially opened notches, with the notches and protrusions being provided in a one-to-one correspondence.
[0011] By further designing the upper cover, an abutment portion is provided, and several protrusions are provided on the abutment portion. Several radially opened notches are provided on the adjusting component, so that the notches and protrusions correspond one-to-one to form a circumferential engagement, thereby ensuring that the upper cover and the adjusting component can rotate synchronously.
[0012] The present invention can be further configured such that: a lower cover is provided on the housing, the lower cover can be assembled with the lower end of the housing to form a mounting groove, and the potentiometer body is disposed in the mounting groove.
[0013] By further designing the housing, a lower cover is added to form a mounting groove with the lower end of the housing. This provides protection and fixation for the potentiometer body, while also facilitating disassembly and adjustment. Attached Figure Description
