Description

Technical Field

[0001] This utility model relates to the field of vehicle in-vehicle central control screen displacement technology, and in particular to a vehicle-mounted central control screen translation mechanism. Background Technology

[0002] With the continuous improvement of automotive intelligence, the central control screen has become a core component for vehicle infotainment and function control. Users' needs for the central control screen are no longer limited to display effects, but extend to its mechanical structure and interaction methods.

[0003] Currently, most central control screens on the market use fixed or simple manual tilt adjustment mechanisms. A few high-end models are equipped with electric adjustment mechanisms, but their structures are mostly based on hinge-based rotation or tilt movements to achieve simple extension and retraction. These hinge mechanisms have several significant drawbacks: First, the movement trajectory is limited, unable to achieve pure linear translation, making it difficult to meet the needs of some novel interior layouts (such as hidden screens); second, hinge mechanisms usually occupy a large space when unfolded, which is not conducive to optimizing the layout of the vehicle's interior space; third, their movement precision and stability are limited, and they are prone to shaking and abnormal noises in the vibration environment of the vehicle, affecting the user experience and premium feel; finally, traditional brushed motors have shortcomings in terms of operating noise and lifespan.

[0004] Therefore, a vehicle-mounted central control screen translation mechanism is provided to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problems in the existing technology, where most central control screens adopt a rotation or pitch-based structure to extend or retract, resulting in a single movement trajectory that cannot achieve pure linear translation. This makes it difficult to meet the needs of some novel interior layouts (such as hidden screens). In addition, they usually occupy a large space after being unfolded, which is not conducive to the optimization of the interior space. They also have limited motion precision and stability, and are prone to shaking and abnormal noise in the vibration environment of vehicle driving, which affects the user experience.

[0006] This utility model provides a vehicle-mounted central control screen translation mechanism, the vehicle-mounted central control screen translation mechanism comprising: The mounting bracket has a drive mechanism fixedly mounted at one end. A lead screw and an auxiliary guide rod are arranged parallel to each other at the same height inside the mounting bracket. The drive mechanism is used to drive the lead screw to rotate. The mounting bracket also includes a slider assembly, which is sleeved on both the lead screw and the auxiliary guide rod and moves along the lead screw nut and the auxiliary guide rod. A screen connection bracket is also fixedly mounted on the slider assembly. A central control screen assembly is fixedly mounted on the end of the screen connection bracket away from the mounting bracket.

[0007] Optionally, it also includes a wire harness box, part of which is fixedly mounted on the lower end face of the mounting bracket. The wire harness box is equipped with a controller, which is located on one side of the drive mechanism and electrically connected to the drive mechanism.

[0008] Optionally, the mounting bracket is fixed to a crossbeam or sheet metal inside the vehicle's center console by screws.

[0009] Optionally, the drive mechanism includes a brushless motor, a coupling, and bearings. Two bearings are respectively fixedly mounted on the side walls of the mounting brackets located at both ends of the lead screw nut. The two bearings are also respectively interference-fitted to both ends of the lead screw nut. The brushless motor is mounted on the wire harness box. The coupling is located between the brushless motor and the mounting bracket. The coupling is used to connect the brushless motor and the lead screw nut.

[0010] Optionally, the mounting bracket has a screen connection slot, and the screen connection bracket extends out of the screen connection slot and moves along the screen connection slot.

[0011] Optionally, the slider assembly includes a nut portion and a slider portion, the nut portion being sleeved on the lead screw and the slider portion being sleeved on the auxiliary guide rod.

[0012] Optionally, the portion of the nut that contacts the lead screw is provided with an internal thread, and the slider portion is provided with a guide hole in the middle or a sliding groove on one side, the guide hole or the sliding groove cooperating with the auxiliary guide rod.

[0013] Optionally, the controller is also connected to the vehicle's CAN bus and power supply.

[0014] This utility model achieves high-precision, high-efficiency, and low-noise linear translational motion through the combination of lead screw and auxiliary guide rod. At the same time, the overall structure is compact, which greatly saves interior space and meets the needs of the electric adjustment mechanism of the central control screen in automobile fleets.

[0020] Example Reference manual attached Figure 1-2 This embodiment provides a vehicle-mounted central control screen translation mechanism, which includes: Mounting bracket 1, with a drive mechanism fixedly mounted at one end of mounting bracket 1. Inside mounting bracket 1, a lead screw 3 and an auxiliary guide rod 4 are arranged parallel to each other at the same height. The drive mechanism is used to drive the lead screw 3 to rotate. It also includes a slider assembly 7, which is sleeved on both the lead screw 3 and the auxiliary guide rod 4 and moves along the nut of the lead screw 3 and the auxiliary guide rod 4. A screen connection bracket is also fixedly mounted on the slider assembly 7. A central control screen assembly 8 is fixedly mounted on the end of the screen connection bracket 9 away from mounting bracket 1.

[0021] It also includes a wire harness box 5, part of which is fixedly mounted on the lower end face of the mounting bracket 1. A controller 6 is mounted on the wire harness box 5. The controller 6 is located on one side of the drive mechanism and is electrically connected to the drive mechanism.

[0022] Mounting bracket 1 is fixedly installed on the crossbeam or sheet metal inside the car's center console using screws.

[0023] The drive mechanism includes a brushless motor 2, a coupling, and bearings. Two bearings are fixedly mounted on the side walls of the mounting bracket 1 located at both ends of the lead screw 3 nut. The two bearings are also interference-fitted to both ends of the lead screw 3 nut. The brushless motor 2 is mounted on the wiring harness box 5. The coupling is located between the brushless motor 2 and the mounting bracket 1. The coupling is used to connect the brushless motor 2 and the lead screw 3 nut.

[0024] The mounting bracket 1 has a screen connection slot, and the screen connection bracket extends out from the screen connection slot and moves along the screen connection slot.

[0025] The slider assembly 7 includes a nut part and a slider part. The nut part is sleeved on the lead screw 3, and the slider part is sleeved on the auxiliary guide rod 4.

[0027] Controller 6 is also connected to the vehicle's CAN bus and power supply.

[0028] Workflow: When the user issues a command to extend or retract the screen, the controller receives the signal and drives the brushless motor to rotate. The output shaft of the brushless motor drives the lead screw to rotate. The nut of the slider assembly, which meshes with the linear lead screw, moves linearly along the axis of the lead screw under the action of helical transmission. Since the screen is fixed to the slider through the screen connecting bracket, the screen translates synchronously. Throughout the movement, the auxiliary guide rod cooperates with the slider assembly to bear the main bending moment and radial force, ensuring the smoothness and straightness of the movement and avoiding potential damage and accuracy loss caused by the lead screw bearing radial force. The cables in the wiring harness box move flexibly synchronously with the screen, ensuring the reliability of the function.
