Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, and in particular to a vehicle display angle adjustment mechanism. Background Technology

[0002] As a core device for human-machine interaction in automobiles, in-vehicle displays integrate key functions such as navigation, multimedia, and vehicle information display, and drivers rely heavily on them. Currently, most in-vehicle displays are fixedly installed, making it impossible to adjust the angle according to the driver's height and driving habits, easily leading to poor viewing angles and affecting user experience and ease of operation. The few adjustable mechanisms available suffer from problems such as high adjustment noise and low motion precision, failing to meet the demands of high-quality driving. Therefore, we propose an in-vehicle display angle adjustment mechanism. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a vehicle-mounted display screen angle adjustment mechanism. This utility model solves the problems mentioned in the background section.

[0004] This utility model provides the following technical solution: a vehicle-mounted display screen angle adjustment mechanism, including a display screen bracket, a display screen, and a rotating mechanism. The rotating mechanism drives the display screen bracket to rotate, thereby driving the display screen to rotate. The rotating mechanism includes a stator, a rotor, a first gear, a second gear, a lead screw shaft, a nut seat, a crank-slider mechanism, a crank, and an output shaft. When the rotor rotates, it drives the first gear to rotate. The first gear drives the second gear to rotate through meshing. The second gear is fixedly connected to the lead screw shaft. The rotation of the lead screw shaft causes the nut seat to move linearly. The nut seat is connected to the crank-slider mechanism for transmission, causing the crank to rotate. The crank is riveted to the output shaft, thereby causing the output shaft to rotate.

[0005] In the above scheme, the stator assembly consists of an upper insulating end cover, a lower insulating end cover, and stator silicon steel sheets, wherein the coil is connected to the three-phase connection pins extending from the upper insulating end cover by clamping and welding.

[0006] The above solution also includes a plastic housing and a gear cover. The plastic housing has three-phase pins. When the plastic housing is pushed into the gear cover, the three-phase pins of the plastic housing make contact with the three-phase connection pins and conduct electricity. There is a pin on the plastic housing that is connected to the PCBA.

[0007] In the above scheme, the rotor assembly has a second magnetic ring, and the output shaft has a first magnetic ring.

[0008] In the above scheme, the rotor assembly has a deep groove ball bearing, the second deep groove ball bearing is interference-fitted and fixed to the rotor shaft, and the first deep groove ball bearing is clearance-fitted to the shaft. It is fixed in the bearing housing of the gearbox by the combined action of the step and the hole retaining ring, and is provided with a shaft retaining ring.

[0009] In the above scheme, the output shaft is connected to a linear bearing, and a flat washer and a retaining ring are connected to the output shaft.

[0010] In the above scheme, there is a deep groove ball bearing on the lead screw shaft, which is fixed to the lead screw shaft by interference fit. The nut seat on the lead screw shaft is also sleeved on the rotor shaft and can slide freely on the rotor shaft.

[0011] The advantages and beneficial effects of this utility model are as follows: This utility model provides a vehicle display screen angle adjustment mechanism. Through the cooperation of various components of the rotating mechanism, the angle of the vehicle display screen can be flexibly adjusted, completely solving the problems of existing equipment being "unadjustable" or having a "poor adjustment experience," and meeting the viewing needs of different drivers.

[0023] 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.

[0024] like Figure 1-9 As shown, this utility model is a vehicle-mounted display screen angle adjustment mechanism, including a display screen bracket 1, a display screen 2, and a rotating mechanism. The rotating mechanism drives the display screen bracket 1 to rotate, which in turn drives the display screen 2 to rotate. The rotating mechanism includes a stator 3, a rotor 4, a first gear 5, a second gear 6, a lead screw shaft 7, a nut seat 8, a crank-slider mechanism 9, a crank 10, and an output shaft 11. When the rotor 4 rotates, it drives the first gear 5 to rotate. The first gear 5 drives the second gear 6 to rotate through meshing. The second gear 6 is fixedly connected to the lead screw shaft 7. The rotation of the lead screw shaft 7 causes the nut seat 8 to move linearly. The nut seat 8 is connected to the crank-slider mechanism 9, which drives the crank 10 to rotate. The crank 10 is riveted to the output shaft 11, which in turn causes the output shaft 11 to rotate.

[0025] Through this series of mechanical transmission structures, the rotational motion of rotor 4 is gradually converted into the rotational motion of output shaft 11, ultimately realizing the angle adjustment of display screen 2. Through the cooperation of various components of the rotating mechanism, the flexible adjustment of the vehicle display screen angle is realized, solving the problem of the existing vehicle display screen angle being non-adjustable and meeting the needs of drivers for different viewing angles.

[0026] In the above scheme, the stator 3 assembly consists of an upper insulating end cover 12, a lower insulating end cover 13, and a stator silicon steel sheet 14. The coil is connected to the three-phase connection pins 15 extending from the upper insulating end cover 12 via clamp welding. This structural design of the stator 3 assembly ensures the stability and safety of the electrical connection of the coil. The upper insulating end cover 12 and the lower insulating end cover 13 provide insulation protection to prevent electrical short circuits and other problems. The stator silicon steel sheet 14 helps to enhance the magnetic field and improve the electromagnetic conversion efficiency. Through the cooperation of the various parts of the stator 3 assembly, the stability and safety of the electrical connection are guaranteed, providing a guarantee for the stable drive of the rotor 4, solving potential electrical fault problems, and improving the reliability of the regulating mechanism.

[0027] The above solution also includes a plastic housing 16 and a gear cover 18. The plastic housing 16 has three-phase pins 17. When the plastic housing 16 is pushed into the gear cover 18, the three-phase pins 17 and three-phase connection pins 15 make contact and conduct. Three pins on the plastic housing 16 are connected to the PCBA1. Through the cooperation of the plastic housing 16 and the gear cover 18, the PCBA1 controls the stator coil 3, making the electrical control of the entire regulating mechanism more convenient and reliable. The cooperation of the plastic housing 16, gear cover 18, and related pins achieves convenient electrical connection and control, ensuring that the regulating mechanism can operate according to the preset program, and solving the problems of complex and unstable electrical control.

[0028] In the above scheme, the rotor 4 assembly has a second magnetic ring 19, and the output shaft 11 has a first magnetic ring 20. Magnetic rings 19 and 20 are used to monitor the positions of the rotor 4 shaft and the output shaft 11, respectively. By cooperating with corresponding sensors, the position information of the shafts can be obtained in real time, providing feedback for precise control of the movement of the adjustment mechanism. Through the cooperation of magnetic rings 19 and 20 with sensors, real-time monitoring of the positions of the rotor 4 shaft and the output shaft 11 is achieved, ensuring the accuracy of the movement and solving the problem of low movement accuracy in existing adjustment mechanisms.

[0029] In the above scheme, the rotor 4 assembly has two deep groove ball bearings. Deep groove ball bearing 21 is interference-fitted and fixed to the rotor shaft, while deep groove ball bearing 22 is clearance-fitted to the shaft. Both are fixed in the gearbox bearing housing by a step and a retaining ring 23, and a shaft retaining ring 24 is also provided. This bearing installation and fixing method ensures both the rotational flexibility of the rotor 4 shaft and restricts its axial movement. The interference fit of deep groove ball bearing 21 ensures a tight connection with the rotor shaft, transmitting rotational power; the clearance fit of deep groove ball bearing 22 and the use of the related retaining ring effectively restrict the axial movement of the shaft. Through the bearing and retaining ring structure on the rotor 4 assembly, stable rotation and axial positioning of the rotor 4 shaft are ensured, reducing mechanical failures and noise caused by shaft movement, and improving the stability and reliability of the adjustment mechanism.

[0030] In the above scheme, the output shaft 11 is connected to the linear bearing 25, and a flat washer 26 and a retaining ring 27 are connected to the output shaft 11. The linear bearing 25 ensures the smoothness of the output shaft 11 during rotation and reduces frictional resistance. The flat washer 26 and retaining ring 27 are used to limit the axial movement of the output shaft 11, ensuring that the output shaft 11 can stably transmit rotational motion to the display screen bracket 1. Through the cooperation of the output shaft 11 with the linear bearing 25, the flat washer 26 and the retaining ring 27, the smoothness of the rotation of the output shaft 11 and its axial stability are ensured, further improving the stability and accuracy of the display screen angle adjustment.

[0031] In the above scheme, the lead screw shaft 7 has two deep groove ball bearings 28, both of which are fixed to the lead screw shaft 7 by interference fit. The nut seat 8 on the lead screw shaft 7 is also sleeved on the rotor shaft and can slide freely on the rotor shaft. The deep groove ball bearings 28 provide support for the rotation of the lead screw shaft 7, ensuring its rotational stability. The nut seat 8, sleeved on the rotor shaft and able to slide freely, achieves linear motion when the lead screw shaft 7 rotates, and through cooperation with the crank-slider mechanism 9, converts the linear motion into the rotational motion of the crank 10. Through the cooperation of the deep groove ball bearings 28 on the lead screw shaft 7 and the nut seat 8, the stable rotation of the lead screw shaft 7 and the linear motion transmission of the nut seat 8 are ensured, ensuring the stable operation of the entire transmission mechanism and improving the working reliability of the adjustment mechanism.

[0032] Working principle:

[0033] This type of vehicle display screen angle adjustment mechanism uses a PCBA to control the energization of the stator coils, driving the rotor to rotate via electromagnetic force. When the angle of the vehicle display screen needs to be adjusted, PCBA1 controls the energization of the coils in stator 3, driving rotor 4 to rotate under the action of electromagnetic force. The rotation of rotor 4 drives the connected gear 5 to rotate, and gear 5, through meshing transmission, causes gear 6 to rotate. Since gear 6 and lead screw 7 are fixedly connected, lead screw 7 rotates accordingly. The rotation of lead screw 7 causes nut seat 8 to move linearly along lead screw 7. During the linear movement, nut seat 8 is connected to crank-slider mechanism 9, pushing crank 10 to rotate. Because crank 10 is riveted to output shaft 11, the rotation of crank 10 drives output shaft 11 to rotate. The rotation of output shaft 11 is ultimately transmitted to display screen bracket 1, thereby realizing the adjustment of the display screen angle.

[0034] Throughout the process, the magnetic ring 19 on rotor 4 and the magnetic ring 20 on output shaft 11 work in conjunction with their respective sensors to monitor the positions of rotor 4 and output shaft 11 in real time. This position information is then fed back to the control system, allowing the system to adjust the energizing method of stator 3 coils as needed, thereby achieving precise adjustment of the display screen 2 angle. Simultaneously, the bearing and retaining ring structures on each component ensure stable shaft rotation and axial positioning, reducing noise and malfunctions during operation and improving the stability and reliability of the entire adjustment mechanism.
