Description

Technical Field

[0001] This application relates to the field of entertainment screen rotation device technology, and in particular to a vehicle-mounted central control entertainment screen rotation device. Background Technology

[0002] With the development of automotive intelligence, in-vehicle infotainment screens have become an important component of modern vehicles. They not only provide navigation, entertainment, and vehicle information display functions, but also play a core role in human-machine interaction. To meet the usage needs of drivers and passengers in different scenarios, the infotainment screen needs to have multi-angle rotation capabilities to adjust to the optimal viewing position. However, traditional fixed screens cannot meet this requirement, hence the development of in-vehicle infotainment screen rotation devices.

[0003] Currently, there are various designs for rotating in-vehicle infotainment screens on the market. The most common solution is to directly drive the screen rotation with a motor. This design typically uses a stepper motor or servo motor as the power source, achieving screen rotation through gears or belts. In addition, some designs employ manual rotation, using mechanical damping structures to stabilize the screen. While these solutions address the screen rotation requirement to some extent, several technical bottlenecks remain.

[0004] Traditional solutions that use a motor to directly drive the central control screen to rotate are prone to causing the screen to shake or shift during rotation due to the inertial impact of the motor starting and stopping, as well as the clearance error of the transmission mechanism, which affects the user experience. Utility Model Content

[0005] The purpose of this application is to solve the problem that the central control screen may shake or shift during rotation due to the inertial impact when the motor starts and stops, as well as the clearance error of the transmission mechanism, which affects the user experience. This application provides a rotating device for a vehicle central control entertainment screen.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A rotating device for a vehicle-mounted central control entertainment screen includes a mounting base with a drive compartment inside. An adjusting gear is rotatably connected to one end of the mounting base, and an annular rotating seat is rotatably connected to the other end. An adjusting gear ring is fixedly connected inside the annular rotating seat. One end of the adjusting gear is installed inside the annular rotating seat and meshes with the adjusting gear ring. A connecting seat is fixedly connected to one side of the annular rotating seat. An L-shaped connecting plate is fitted onto one end of the connecting seat. Guide grooves are symmetrically formed inside the L-shaped connecting plate. Guide sliders adapted to the guide grooves are symmetrically fixedly connected to one end of the connecting seat. A slot is formed at one end of the L-shaped connecting plate, and a rod is inserted into the slot. A central control screen is fixedly connected to one end of the rod. A rotating assembly is installed inside the mounting base, and a locking assembly is installed at one end of the rod.

[0008] By adopting the above technical solution, and by setting up the coordinated use of adjusting gears and adjusting rings, guide grooves and guide sliders, it is convenient to use the diameter difference between the adjusting gears and adjusting rings to drive the annular rotating seat to rotate at a reduced speed when the rotating component is started and the adjusting gears and adjusting rings are engaged. At the same time, the annular rotating seat drives the connecting seat to cooperate with the L-shaped connecting plate to drive the central control screen to deflect at a reduced speed. This effectively improves the deflection stability of the central control screen and reduces the impact on the user experience caused by the central control screen shaking or shifting during rotation.

[0009] Furthermore, the rotating assembly includes a worm gear fixedly connected to one end of the adjusting gear, a worm gear meshing with the worm gear is rotatably connected inside the drive chamber, a rotary motor is fixedly connected to one end of the mounting base, and the output end of the rotary motor is fixedly connected to the worm gear.

[0010] By adopting the above technical solution and setting up the cooperation between the worm and the worm wheel, the starting rotary motor can drive the worm and the worm wheel to mesh, thereby causing the worm wheel to drive the adjusting gear to rotate, which effectively improves the practicality of the device.

[0011] Furthermore, the locking assembly includes a locking screw head fixedly connected to one end of the insertion rod, and a locking nut is threadedly connected to one end of the locking screw head.

[0012] By adopting the above technical solution, and by setting the locking screw head and locking nut to work together, it is easy to tighten the locking nut so that the locking nut pushes the L-shaped connecting plate along the length of the plug rod to form a fixed contact with the central control screen, thereby realizing the fixed connection between the L-shaped connecting plate and the central control screen, which effectively improves the practicality of the device.

[0013] Furthermore, a rubber ring is fixedly connected to the inner side of the slot, and the insertion rod is inserted inside the rubber ring.

[0014] By adopting the above technical solution, and by setting the rubber ring sleeve and the insertion rod to cooperate, the insertion rod can form a flexible contact with the inner wall of the slot through the rubber ring sleeve, thereby effectively reducing the wear between the insertion rod and the slot, reducing the noise generated when the insertion rod and the slot rub against each other, and further improving the practicality of the device.

[0015] Furthermore, the connecting seat has a buffer chamber inside, and the inner side of the buffer chamber has symmetrical buffer grooves. The buffer grooves are slidably connected to an abutment ring plate. The buffer chamber is fixedly connected to a damper. The top of the damper is fixedly connected to the abutment ring plate. One end of the connecting seat is fitted with an abutment spring. One end of the abutment spring is fixedly connected to the abutment ring plate. A fixing component is installed at one end of the connecting seat.

[0016] By adopting the above technical solution, and by setting up the fixed components in conjunction with the damper and the contact spring, when the central control screen is affected by inertia and pushes the L-shaped connecting plate to move along the length of the connecting seat, the L-shaped connecting plate pushes the contact ring plate to form contact with the damper and the contact spring, causing the damper and the contact spring to contract and deform under force, while absorbing part of the inertial force transmitted by the L-shaped connecting plate, so as to reduce the shaking amplitude of the central control screen and further improve the rotational stability of the central control screen.

[0017] Furthermore, the fixing component includes a fixing screw groove formed at one end of the connecting seat, and a T-shaped fixing screw adapted to the L-shaped connecting plate is threaded into the fixing screw groove.

[0018] By adopting the above technical solution, and by setting the T-shaped fixing screw and the fixing screw groove to cooperate, when the L-shaped connecting plate is sleeved on one end of the connecting seat, the T-shaped fixing screw and the fixing screw groove are tightened to form a threaded connection, so that the L-shaped connecting plate can be slidably installed between the annular rotating seat and the T-shaped fixing screw, which effectively improves the practicality of the device.

[0019] Furthermore, an annular rubber pad one is fixedly connected to one side of the contact ring plate, an annular rubber pad two is fixedly sleeved on one end of the T-shaped fixing screw, and the L-shaped connecting plate is installed between the annular rubber pad one and the annular rubber pad two.

[0020] By adopting the above technical solution, and by setting the cooperation of annular rubber pad one and annular rubber pad two, the L-shaped connecting plate forms a flexible contact with the contact ring plate and T-shaped fixing screw through annular rubber pad one and annular rubber pad two, which effectively reduces the wear on the surface of the L-shaped connecting plate and extends the service life of the device.

[0021] Furthermore, a corrugated sleeve is fixedly connected to one end of the abutment ring plate, the corrugated sleeve is sleeved around the abutment spring, and the other end of the corrugated sleeve is fixedly connected to the annular rotating seat.

[0022] By adopting the above technical solution, and by using the corrugated sleeve in conjunction with the anti-spring, it is easy to form a protective enclosure around the anti-spring, effectively reducing the impact of external forces on the anti-spring and improving the practicality of the device.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By setting up the coordination of adjusting gears and adjusting rings, and guide grooves and guide sliders, when the rotating component is started and the adjusting gears and adjusting rings are engaged, the diameter difference between the adjusting gears and adjusting rings is used to drive the annular rotating seat to rotate at a reduced speed. At the same time, the annular rotating seat drives the connecting seat to work with the L-shaped connecting plate to drive the central control screen to deflect at a reduced speed. This effectively improves the deflection stability of the central control screen and reduces the impact on the user experience caused by the central control screen shaking or shifting during rotation.

[0025] 2. By using a fixed component in conjunction with a damper and a contact spring, when the central control screen is affected by inertia and pushes the L-shaped connecting plate to move along the length of the connecting seat, the L-shaped connecting plate pushes the contact ring plate to form contact with the damper and the contact spring, causing the damper and the contact spring to contract and deform under force. At the same time, it absorbs part of the inertial force transmitted by the L-shaped connecting plate, thereby reducing the swaying amplitude of the central control screen and further improving the rotational stability of the central control screen.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a rotating device for a vehicle-mounted central control entertainment screen.

[0034] Reference Figure 1 - Figure 4 A rotating device for a vehicle-mounted central control entertainment screen includes a mounting base 1, a drive compartment 2 inside the mounting base 1, an adjusting gear 3 rotatably connected to one end of the mounting base 1, an annular rotating seat 4 rotatably connected to one end of the mounting base 1, an adjusting gear ring 5 fixedly connected inside the annular rotating seat 4, one end of the adjusting gear 3 being installed inside the annular rotating seat 4 and meshing with the adjusting gear ring 5, a connecting seat 6 fixedly connected to one side of the annular rotating seat 4, an L-shaped connecting plate 7 sleeved on one end of the connecting seat 6, guide grooves 26 symmetrically opened inside the L-shaped connecting plate 7, guide sliders 27 adapted to the guide grooves 26 symmetrically fixedly connected to one end of the connecting seat 6, a slot 8 opened on one end of the L-shaped connecting plate 7, a rod 9 inserted inside the slot 8, a central control screen 10 fixedly connected to one end of the rod 9, a rotating assembly installed inside the mounting base 1, and a locking assembly installed at one end of the rod 9.

[0035] The rotating assembly includes a worm gear 11 fixedly connected to one end of the adjusting gear 3, a worm 12 meshing with the worm gear 11 rotatably connected inside the drive chamber 2, and a rotary motor 13 fixedly connected to one end of the mounting base 1, with the output end of the rotary motor 13 fixedly connected to the worm 12.

[0036] Furthermore, the locking assembly includes a locking screw head 14 fixedly connected to one end of the insertion rod 9, and a locking nut 15 is threadedly connected to one end of the locking screw head 14;

[0037] Furthermore, a rubber ring 16 is fixedly connected to the inner side of the slot 8, and the insertion rod 9 is inserted into the inside of the rubber ring 16.

[0038] In use, the central control screen 10 is first manually pulled to deflect around the insert rod 9 as the axis to adjust the deflection angle of the central control screen 10 along the axis of the insert rod 9. At the same time, the insert rod 9 compresses the rubber ring 16 to deform, and the elastic properties of the rubber ring 16 are used to make the rubber ring 16 rebound and form abutment with the insert rod 9. This improves the rotation damping effect of the central control screen 10 around the insert rod 9 as the axis, reduces the wear between the insert rod 9 and the slot 8, and reduces the noise generated by the friction between the insert rod 9 and the slot 8 when rotating. Then, the locking nut 15 and the locking screw head 14 are manually tightened to form a threaded connection, and the L-shaped connecting plate 7 is pushed to form a fixed abutment with the central control screen 10. This facilitates the deflection adjustment of the central control screen 10 around the insert rod 9 as the axis and improves the practicality of the device.

[0039] Then, after the L-shaped connecting plate 7 is pulled to align the guide groove 26 with the guide slider 27 and is fitted onto one end of the connecting seat 6, the rotating motor 13 is started to drive the worm gear 12 to mesh with the worm wheel 11. This allows the worm wheel 11 to drive the adjusting gear 3 to rotate synchronously, thereby driving the adjusting gear 3 to mesh with the adjusting gear ring 5. The difference in diameter between the adjusting gear 3 and the adjusting gear ring 5 is used to reduce the speed. At the same time, the adjusting gear 3 is installed inside the annular rotating seat 4 to reduce the area occupied by the adjusting gear 3 and the adjusting gear ring 5. This allows the adjusting gear ring 5 to drive the annular rotating seat 4 and the connecting seat 6 to rotate at a reduced speed. Consequently, the connecting seat 6 drives the guide slider 27 to abut against the inner wall of the guide groove 26, and pulls the L-shaped connecting plate 7 to drive the central control screen 10 to deflect around the connecting seat 6 as the axis. This facilitates the deceleration and deflection of the central control screen 10, effectively improving the deflection stability of the central control screen 10 and reducing the impact on the user experience caused by the central control screen shaking or shifting during rotation.

[0040] Reference Figure 2 and Figure 4 The connecting seat 6 has a buffer chamber 17 inside, and a buffer groove 18 is symmetrically provided on the inner side of the buffer chamber 17. A contact ring plate 19 is slidably connected inside the buffer groove 18. A damper 20 is fixedly connected inside the buffer chamber 17. The top of the damper 20 is fixedly connected to the contact ring plate 19. A contact spring 21 is sleeved on one end of the connecting seat 6. One end of the contact spring 21 is fixedly connected to the contact ring plate 19. A fixing component is installed on one end of the connecting seat 6.

[0041] The fixing component includes a fixing screw groove 22 opened at one end of the connecting seat 6, and a T-shaped fixing screw 23 adapted to the L-shaped connecting plate 7 is threaded inside the fixing screw groove 22.

[0042] Furthermore, an annular rubber pad 24 is fixedly connected to one side of the contact ring plate 19, an annular rubber pad 25 is fixedly sleeved on one end of the T-shaped fixing screw 23, and an L-shaped connecting plate 7 is installed between the annular rubber pad 24 and the annular rubber pad 25.

[0043] Furthermore, a corrugated sleeve 28 is fixedly connected to one end of the contact ring plate 19. The corrugated sleeve 28 is sleeved around the contact spring 21, and the other end of the corrugated sleeve 28 is fixedly connected to the annular rotating seat 4.

[0044] In use, when the L-shaped connecting plate 7 is pulled to drive the guide groove 26 to be fitted onto one end of the guide slider 27, one end of the L-shaped connecting plate 7 abuts against the contact ring plate 19 along the length of the connecting seat 6, and the contact ring plate 19 is subjected to force along the length of the connecting seat 6, pushing the contact spring 21 to contract and deform. Then, by manually pulling the T-shaped fixing screw 23 through one end of the L-shaped connecting plate 7, a threaded connection is formed with the fixing screw groove 22. At the same time, the T-shaped fixing screw 23 pushes the annular rubber pad 25 to abut against one side of the L-shaped connecting plate 7. Then, by utilizing the rebound characteristic of the contact spring 21, the contact spring 21 pushes the contact ring plate 19 to drive the annular rubber pad 24 to abut against one side of the L-shaped connecting plate 7, thereby facilitating the fixed abutment of the L-shaped connecting plate 7.

[0045] Then, when the vehicle shakes, causing the L-shaped connecting plate 7 to sway along the length of the connecting seat 6 under the action of inertia, the L-shaped connecting plate 7 pushes the abutment ring plate 19 to slide along the length of the buffer groove 18, and squeezes the damper 20 and the abutment spring 21 to produce contraction deformation. At the same time, the abutment spring 21 and the damper 20 contract and absorb part of the inertial force transmitted by the L-shaped connecting plate 7, so as to reduce the swaying amplitude of the L-shaped connecting plate 7, thereby improving the installation stability of the central control screen 10. Meanwhile, the corrugated sleeve 28 is set to wrap around the abutment spring 21, effectively reducing the influence of external forces on the abutment spring 21 and improving the practicality of the device.

[0046] The implementation principle of the vehicle central control entertainment screen rotation device in this embodiment is as follows: First, the central control screen 10 is manually pulled to deflect around the insertion rod 9 as the axis to adjust the deflection angle of the central control screen 10 along the axis of the insertion rod 9. Then, the locking nut 15 and the locking screw head 14 are manually tightened to form a threaded connection, and the L-shaped connecting plate 7 is pushed to form a fixed contact with the central control screen 10.

[0047] Then, when the L-shaped connecting plate 7 is pulled to drive the guide groove 26 to be fitted onto one end of the guide slider 27, one end of the L-shaped connecting plate 7 will abut against the contact ring plate 19 along the length of the connecting seat 6, and the contact ring plate 19 will be subjected to force along the length of the connecting seat 6, pushing the contact spring 21 to contract and deform. Then, by manually pulling the T-shaped fixing screw 23 through one end of the L-shaped connecting plate 7, a threaded connection will be formed with the fixing screw groove 22. At the same time, the T-shaped fixing screw 23 will push the annular rubber pad 25 to abut against one side of the L-shaped connecting plate 7. Then, by utilizing the rebound characteristic of the contact spring 21, the contact spring 21 will push the contact ring plate 19 to drive the annular rubber pad 24 to abut against one side of the L-shaped connecting plate 7.

[0048] Next, after the L-shaped connecting plate 7 is fitted onto one end of the connecting seat 6, the rotating motor 13 is started to drive the worm 12 to mesh with the worm wheel 11. This allows the worm wheel 11 to drive the adjusting gear 3 to rotate synchronously, thereby driving the adjusting gear 3 to mesh with the adjusting gear ring 5. The difference in diameter between the adjusting gear 3 and the adjusting gear ring 5 is used to reduce the speed. At the same time, the adjusting gear 3 is installed inside the annular rotating seat 4 to reduce the area occupied by the adjusting gear 3 and the adjusting gear ring 5. This allows the adjusting gear ring 5 to drive the annular rotating seat 4 and the connecting seat 6 to rotate at a reduced speed. This causes the connecting seat 6 to drive the guide slider 27 to abut against the inner wall of the guide groove 26, and to drive the L-shaped connecting plate 7 to drive the central control screen 10 to deflect around the connecting seat 6 as the axis.

[0049] Meanwhile, when the vehicle shakes, causing the L-shaped connecting plate 7 to sway along the length of the connecting seat 6 under the action of inertia, the L-shaped connecting plate 7 pushes the abutment ring plate 19 to slide along the length of the buffer groove 18, and squeezes the damper 20 and the abutment spring 21 to produce contraction deformation. At the same time, the abutment spring 21 and the damper 20 contract and absorb part of the inertial force transmitted by the L-shaped connecting plate 7, so as to reduce the swaying amplitude of the L-shaped connecting plate 7, thereby improving the installation stability of the central control screen 10.
