Description

Vehicle-mounted display screen fixing device Technical Field The invention belongs to the field of automotive interiors, and relates to a vehicle-mounted display screen fixing device. Background With the popularization of intelligent automobiles, the on-board display screen 6 has become a core component of man-machine interaction. In the prior art, the following problems mainly exist in the fixing mode of the vehicle-mounted display screen 6: 1. the traditional buckle type fixing is easy to loosen due to bumping of the vehicle, and the touch control precision is affected; 2. The visual angle adjustment is limited, wherein most fixing frames only support single-axis rotation, and the requirements of primary and secondary driving collaborative viewing cannot be met; 3. the damping performance is insufficient, no special buffer structure is arranged, and the cable connector of the display screen 6 is easy to damage due to long-term vibration; 4. the disassembly and assembly efficiency is low, a plurality of screws are required to be disassembled by means of tools during maintenance, and the operation is time-consuming. Therefore, a new fixing device integrating stable fixing, multidimensional adjustment, shock absorption protection and rapid disassembly and assembly functions is needed. Disclosure of Invention The invention provides a vehicle-mounted display screen fixing device which aims to overcome at least one defect of the prior art. In order to achieve the aim, the invention adopts the following technical scheme that the vehicle-mounted display screen fixing device comprises a base component, wherein the bottom of the base component is provided with a sucker type adsorption structure, and the top of the base component is provided with a T-shaped groove sliding rail; the rotation adjusting mechanism comprises a horizontal rotating seat which is in sliding connection with the T-shaped groove sliding rail, and a pitching adjusting arm hinged with the horizontal rotating seat; the damping buffer component comprises an outer frame, a silica gel damping layer and a compression spring and is used for damping and buffering; the quick-release locking mechanism comprises a magnetic attraction buckle, a guide rail sliding block and a locking piece. Further, the number of the sucking discs of the base assembly is 3, and the sucking discs are distributed in an equilateral triangle shape. Further, a deep groove ball bearing is arranged between the horizontal rotating seat and the T-shaped groove sliding rail, and the pin shaft fit clearance of the pitching adjusting arm is 0.05-0.1mm. Further, the inner wall of the outer frame of the shock absorption buffer assembly is provided with a limiting boss. Further, the horizontal adjustment range of the horizontal rotary seat is 0-360 degrees, and the pitch angle range of the pitch adjustment arm is-15 degrees to +30 degrees. In summary, the invention has the following advantages: The sucking disc type base is suitable for the surfaces of instrument tables with different curvatures, and can achieve fine adjustment of +/-20 mm positions by matching with the T-shaped groove sliding rail. The double-shaft rotating structure enables the horizontal adjusting range of the display screen to reach 360 degrees, the pitching adjusting range to reach-15 degrees to +30 degrees, and the requirement of multi-view viewing is met. The vibration absorption component can absorb vibration energy in the frequency range of 5-200Hz, and reduce the failure rate of the internal elements of the display screen 6. The quick-dismantling mechanism can be dismantled and assembled by manual operation through double fixation of magnetic attraction and mechanical locking, and the time is less than 10 seconds.
