[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] like Figure 1-6 As shown, this utility model is a vehicle-mounted display screen angle adjustment mechanism, including a display screen 1 fixed on a display screen bracket 2. A rotating mechanism 3 is connected to the bottom of the display screen bracket 2. The rotating mechanism 3 includes a gearbox 4 and a gear cover 5. A rotating assembly 6 is disposed inside the gearbox 4. The rotating assembly 6 includes a rotor assembly 61 and a stator assembly 63. The rotor assembly 61 includes a worm gear 62, which is connected to a worm wheel 7. A worm wheel shaft 8 is disposed at the bottom of the worm wheel 7. A full gear 9, coaxial with the worm wheel 7, is disposed on the worm wheel shaft 8. A half gear 10 meshes with the side of the full gear 9. An output shaft 11 is fixedly connected below the half gear 10. A magnetic ring 12 is disposed on the half gear 10. A magnetic ring 13 is disposed on the rotor assembly 61. This structure, through a primary worm gear transmission and a secondary gear transmission, can transmit power from the rotor assembly to the output shaft 11, thereby driving the vehicle-mounted display screen 1 fixed on the display screen bracket 2 to rotate, thus achieving display screen angle adjustment. This multi-stage transmission method allows for reasonable speed and direction changes in rotation, making the display screen rotate more smoothly. The output shaft 11 rotates via a primary worm gear transmission and a secondary gear transmission. The output shaft 11 then further rotates the vehicle-mounted display screen 1, which is fixed to the display screen bracket 2. This solves the problem that most current vehicle-mounted displays are fixed to the dashboard and cannot be flexibly adjusted in terms of angle.

[0022] In the above scheme, the stator assembly 63 includes a lower insulating end cover 631, a stator silicon steel sheet 632, an upper insulating end cover 633, and a three-phase pin bracket. The lower insulating end cover 631 and the upper insulating end cover 633 provide electrical insulation, preventing electrical leakage and other safety issues between the internal electrical components of the stator assembly 63 and the external environment. The stator silicon steel sheet 632 is an important part of the electromagnetic circuit. Working in conjunction with the three-phase pin bracket, it enables the rational distribution of current and the effective generation of the magnetic field, providing power to drive the rotor assembly 61. The lower insulating end cover 631, the stator silicon steel sheet 632, the upper insulating end cover 633, and the three-phase pin bracket work together to ensure the electrical insulation and electromagnetic conversion functions of the stator assembly 63, providing a foundation for the stable operation of the entire rotating mechanism 3.

[0023] In the above scheme, a stator housing 64 is provided at the end of the stator assembly 63. The stator housing 64 mainly serves to protect the internal structure of the stator assembly 63, preventing external dust, moisture, and other impurities from entering, while also enhancing the overall stability of the stator assembly 63, allowing it to function normally even under vibration during vehicle operation. The stator housing 64 protects the internal structure of the stator assembly 63 and enhances its overall stability, extending the service life of the stator assembly 63 and improving the reliability of the rotating mechanism 3.

[0024] In the above scheme, the rotor assembly 61 has two deep groove ball bearings 14, installed with an interference fit on the inner ring and a clearance fit on the outer ring. This installation method of the deep groove ball bearings 14 can reduce the frictional resistance when the rotor assembly 61 rotates, allowing the rotor shaft to rotate more smoothly and ensuring efficient power transmission. The interference fit on the inner ring ensures a tight connection between the bearing and the rotor shaft, while the clearance fit on the outer ring allows for a certain amount of installation error and thermal expansion and contraction. The installation of two deep groove ball bearings 14 with an interference fit on the inner ring and a clearance fit on the outer ring reduces the frictional resistance when the rotor assembly 61 rotates, improves the transmission efficiency of the rotating mechanism 3, and makes the adjustment of the display screen smoother.

[0025] In the above scheme, linear bearings 15 are connected to both the worm gear shaft 8 and the output shaft 11. A flat washer 16 and a retaining ring 17 are provided at the bottom of each linear bearing 15. The linear bearings 15 ensure the smoothness of rotation of the worm gear shaft 8 and the output shaft 11, reducing jamming during operation. The flat washer 16 and retaining ring 17 provide axial positioning; the flat washer 16 provides support, and the retaining ring 17 engages in a retaining ring groove on the shaft to prevent axial movement of the two shafts during rotation. The linear bearings 15 on the worm gear shaft 8 and the output shaft 11 ensure the smoothness of rotation, and the flat washer 16 and retaining ring 17 prevent axial movement, further improving the motion accuracy and stability of the rotating mechanism 3.

[0026] In the above scheme, the rotating mechanism 3 also includes an electric control module connected to the rotor assembly 61. The electric control module enables precise control of the rotor assembly 61's movement, allowing users to conveniently adjust the display screen angle by operating relevant buttons or switches. This module can change the energizing mode of the coils in the stator assembly 63 according to a preset program or real-time user operation, thereby driving the rotor assembly 61 to rotate as required. The electric control module, connected to the rotor assembly 61, enables electric adjustment of the vehicle-mounted display screen angle, improving user convenience.

[0027] In the above scheme, both the gearbox 4 and the gear cover 5 have connecting holes, and the two are fixedly connected by bolts. Fixing the gearbox 4 and gear cover 5 with bolts facilitates the assembly and maintenance of the rotating mechanism 3. During production, internal rotating components 6 and other parts can be easily installed into the gearbox 4, then the gear cover 5 is closed and the bolts are tightened. During later maintenance, it can also be easily disassembled for inspection or replacement of parts. The bolted connection between the gearbox 4 and gear cover 5 facilitates the assembly and maintenance of the rotating mechanism 3, reducing production and maintenance costs.

[0028] Working principle:

[0029] This type of vehicle-mounted display screen angle adjustment mechanism uses a rotating mechanism 3 to drive the display screen bracket 2 to rotate, thereby causing the display screen 1 to rotate. The specific motion transmission process is as follows:

[0030] First, the electric control module controls the energization of the coils in the stator assembly 63. Based on the principle of electromagnetic induction, the rotor assembly 61 is driven to rotate under the action of electromagnetic force. The worm 62 on the rotor assembly 61 rotates accordingly, and the worm 62 and the worm wheel 7 undergo a first-stage worm gear transmission, driving the worm wheel 7 to rotate. The worm wheel shaft 8 at the bottom of the worm wheel 7 also rotates, and the full gear 9 fixed on the worm wheel shaft 8 rotates synchronously. The full gear 9 and the half gear 10 undergo a second-stage gear transmission, driving the half gear 10 to rotate. The half gear 10 is fixed on the output shaft 11, thereby realizing the transmission of motion and enabling the output shaft 11 to complete the rotational motion. The rotation of the output shaft 11 ultimately drives the display screen bracket 2 and the display screen 1 to rotate, realizing the adjustment of the display screen angle. In this process, the lower insulating end cover 631 and the upper insulating end cover 633 in the stator assembly 63 ensure electrical insulation, the stator silicon steel sheet 632 participates in the formation of the electromagnetic circuit, and the three-phase pin bracket realizes the current distribution. After the gearbox 4 and gear cover 5 are fixed with bolts through the connecting holes, the pins on the gear cover 5 will be inserted into the three-phase pin interface, thereby connecting the PCBA on the gear cover 5 with the three-phase winding coil of the stator assembly 63 to complete the driving of the rotor assembly 61.

[0031] The second magnetic ring 13 on the rotor assembly 61 is used to monitor the rotation angle of the rotor. The first magnetic ring 12 on the output shaft 11, together with the second magnetic ring 13, enables real-time monitoring of the position of the output shaft 11, so as to accurately control the rotation angle of the display screen. The two deep groove ball bearings 14 on the rotor assembly 61, through the fit of inner ring interference and outer ring clearance, ensure the smooth rotation of the rotor shaft. The linear bearings 15 on the worm gear shaft 8 and the output shaft 11 ensure the smoothness of the shaft during rotation, and the flat washer 16 and the retaining ring 17 prevent axial movement of the two shafts.

[0032] The user sends a command to the electric control module to adjust the display screen angle by operating a control button or switch connected to the electric control module. The electric control module changes the energizing mode of the coils in the stator assembly 63 according to the command, driving the rotor assembly 61 to rotate as required. Through the above motion transmission process, the output shaft 11 drives the display screen 1 to rotate to the appropriate angle. During the adjustment process, magnetic ring 12 and magnetic ring 13 provide real-time feedback of the position information of the output shaft 11 and the rotor shaft to the electric control module. The electric control module makes precise adjustments based on this information to ensure that the display screen 1 accurately reaches the user's desired angle position.
