Solution Overview
Problem
Existing vehicle-mounted multimedia display screens are fixed in either a horizontal or vertical state, failing to adapt to user preferences for different applications, leading to poor user experience.
Innovation Solution
A vehicle-mounted display screen device with a motor and transmission system that allows switching between horizontal and vertical orientations, incorporating an overload protection mechanism to prevent damage and extend service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen is fixed in a horizontal or vertical state, then the structure is simple and reliable, but the adaptability to different user preferences and applications is poor
Solution Approach 1:
The display screen is designed to be rotatable between horizontal and vertical orientations through a motor-driven transmission system. The screen can dynamically change its orientation state based on different application scenarios and user preferences, transforming from a static fixed structure to a dynamic adjustable structure that adapts to different usage requirements
Solution Approach 2:
The display screen device is designed to perform multiple functions by switching between horizontal and vertical screen states. This multi-functional design allows the same device to adapt to different user preferences and application scenarios (such as different driving conditions, different media consumption modes), thereby improving versatility without requiring multiple separate devices
2Adaptability or versatility
If the display screen is made rotatable to switch between horizontal and vertical states, then the adaptability and user experience are improved, but the risk of overload damage to the motor and transmission system increases
Solution Approach 1:
A semi-clutch mechanism is introduced into the transmission system that can automatically disengage when overload occurs. This protective mechanism is built into the system in advance, so when abnormal forces or overload conditions occur during screen rotation, the semi-clutch automatically disconnects the power transmission to prevent damage to the motor and other transmission components, ensuring system reliability
Solution Approach 2:
The semi-clutch acts as an intermediary protective element between the motor and the transmission system. It serves as a mediator that can automatically disconnect the power transmission path when overload conditions are detected, protecting the motor and transmission components from damage while allowing the screen rotation function to operate normally under normal conditions

Function Achieved in This Case
Enables flexible orientation to meet user preferences, improving user experience while protecting the system from overload damage and prolonging its service life.
Implementation Method 1
an elastic component, the elastic component applies axial elastic force to the first semi-clutch to enable the first tooth and the second tooth to be engaged

AI summary
A vehicle-mounted display screen device includes a display screen, a motor and a transmission system. The motor drives the display screen to rotate via the transmission system. The transmission system includes a first shaft, a second shaft, a first semi-clutch, a second semi-clutch and an elastic component, the first shaft is coaxial with the second shaft, the first semi-clutch is slidably sleeved on the first shaft axially, the second semi-clutch is connected to the second shaft, a first tooth is formed on an end surface of the first semi-clutch facing the second semi-clutch, a second tooth is formed on an end surface of the second semi-clutch facing the first semi-clutch, and the elastic component applies axial elastic force to the first semi-clutch to enable the first tooth and the second tooth to be engaged.
