Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to an adjustable central control screen mechanism. Background Technology

[0002] With the rapid development of the automotive industry, people's demands for cars are also increasing. As a crucial component of the dashboard, the car's central control screen houses many control functions, such as reversing camera, navigation, phone calls, and music and movie playback. However, most existing car central control screens are fixed, meaning their angle cannot be adjusted; this reduces ease of operation and safety. For example, when the driver and front passenger need to use the central control screen, the fixed angle requires them to lean forward, making operation inconvenient. Similarly, when the driver uses the reversing camera function, the fixed angle causes glare, hindering the driver's visibility and reducing safety. Improving the ease of operation of the central control screen is not only a matter of comfort but also of driving safety; therefore, improvements to the existing car central control screen structure are necessary.

[0003] Chinese utility model patent document CN210191368U discloses an installation structure for a car center console screen, including a center console, a center console screen, and a mounting bracket. The mounting bracket is rotatably connected to both the center console screen and the center console. The mounting bracket can swing back and forth relative to the center console, and the center console screen can swing left and right relative to the mounting bracket, thus achieving multi-angle free adjustment of the center console screen. The mounting bracket is rotatably connected to the center console, and the center console screen is rotatably connected to the mounting bracket, allowing the center console screen to be adjusted in height and angle according to the operator's needs. However, this structure relies simply on the rotational connection of a boss and a rotating hole to achieve center console screen angle adjustment, resulting in poor stability. Especially during vehicle operation, unavoidable vibrations can cause random swaying of the center console screen angle adjustment structure, affecting the driver's normal observation of the screen. To improve the comfort of viewing the center console screen, further angle adjustments may be necessary, causing inconvenience and safety hazards for the driver. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the various embodiments of this invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this invention to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0036] The first embodiment of the present invention relates to an adjustable central control screen mechanism. For example... Figure 1-5 As shown, it includes a central control screen 100, a base 200, and a drive mechanism 300 that is rotatably connected to the base 200 and the central control screen 100 respectively. The central control screen 100 can move relative to the base 200 under the drive of the drive mechanism 300. A guide mechanism is provided connected to the base 200, and the guide mechanism is used to limit the movement trajectory of the central control screen 100.

[0037] The drive mechanism 300 includes a support 310 and a motor 320 fixedly mounted at one end of the support 310. The motor output shaft 321 of the motor 320 is positioned toward the central control screen 100. The one end is provided with a first connector 313, which is hinged to the base 200, so that the support 310 can rotate relative to the base 200 in the horizontal direction about the first hinge axis 3131. Preferably, the motor 320 is disposed between the sleeve 311 and the first connector 313. The drive mechanism 300 also includes a cantilever 6 that is connected to the motor output shaft 321 via a sliding screw drive. The motor output shaft 321 has an external thread, and the end of the cantilever 6 near the motor 320 has an internal thread that engages with the motor output shaft 321. The cantilever 6 and the motor output shaft 321 form a sliding screw drive connection, meaning that the cantilever 6 can perform axial extension and retraction under the rotation of the motor 320. The end of the cantilever 6 that engages with the motor output shaft 321 can be tapped using conventional machining methods. The cantilever 6 has a space extending axially along the internal thread inside, which is used to accommodate the sliding screw drive stroke between the motor output shaft 321 and the cantilever 6. Alternatively, if there is a reserved space for axial extension inside the cantilever 6, a nut can be fixedly installed at the end of the cantilever 6 that engages with the motor output shaft 321, and the sliding screw drive between the cantilever 6 and the motor output shaft 321 can be achieved through the thread engagement between the nut and the motor output shaft 321.

[0038] Preferably, a bracket 4 is fixedly provided at one end of the central control screen 100 facing the drive mechanism 300, and a second connector 62 is provided at the end of the cantilever 6 away from the motor 320. The second connector 62 is hinged to the bracket 4, so that the central control screen 100 and the cantilever 6 can rotate relative to each other horizontally about the second hinge axis 621. A limiting hole 41 is provided through the middle of the bracket 4. The limiting hole 41 is an oblong hole. Preferably, the limiting hole 41 is perpendicular to the central axis of the cantilever 6 along its length. To ensure parallelism, the bracket 4 is movably connected to the base 200 via a bushing 5. The bushing 5 includes a connecting shaft 51 and a connecting cap 52. The connecting shaft 51 of the bushing 5 passes through a limiting hole 41 and is fixedly mounted on the base 200. The connecting shaft 51 and the limiting hole 41 are in clearance fit. The bracket 4 can rotate around the connecting shaft 51 and slide along the length of the limiting hole 41. The diameter of the connecting cap 52 is larger than the width of the limiting hole 41, so that the connecting cap 52 stops on one side of the limiting hole 41. When the cantilever 6 extends and retracts, it causes the central control screen 100 to shift. The central control screen 100 rotates around the connecting shaft 51 and slides along the length of the limiting hole 41 with the bracket 4, thereby limiting the movement trajectory of the central control screen 100 through the fit between the limiting hole 41 and the connecting shaft 51.

[0039] Preferably, to increase the stability of the cantilever 6 during telescopic movement, the support 310 is provided with a hollow sleeve 311 extending along the direction of the motor output shaft 321, with the motor output shaft 321 facing the sleeve 311. The cantilever 6 is housed within the sleeve 311. Preferably, the motor output shaft 321 and the sleeve 311 are coaxially arranged. A limiting post 61 is fixedly provided at one end of the cantilever 6 near the motor output shaft 321. A limiting post 61 extends axially along the side wall of the sleeve 311. The column 61 is fitted with a limiting groove 312, and the limiting column 61 slides in the limiting groove 312. The limiting column 61 slides in the limiting groove 312 as the cantilever 6 moves telescopically. The side wall of the limiting groove 312 limits the limiting column 61 in a direction perpendicular to the axis of the cantilever 6 to prevent the cantilever 6 from overturning during movement. Preferably, a bearing is sleeved on the limiting column 61, and the limiting column 61 slides in the limiting groove 312 through the bearing, so that the telescopic movement of the cantilever 6 is more stable and smooth.

[0040] To further improve the shock resistance and stability of the central control screen 100 during adjustment, a support column 314 is fixedly installed on the side wall of the support 310 facing the base 200. Preferably, the support column 314 is located directly below the sleeve 311. A corresponding groove 210 is provided on the base 200 to cooperate with the support column 314. The groove 210 is arc-shaped, and its specific shape can be set according to the position of the support column 314 and the movement trajectory of the support column 314 during the adjustment of the central control screen 100. The component passes through the slide groove 210 and connects to the support column 314, so that the support 310 is stopped and limited by the base 200 in the axial direction. During the adjustment of the central control screen 100, the support column 314 slides with the slide groove 210, and the support column 314 is stopped and limited by the base 200 in its axial direction. The support 310 can move horizontally relative to the base 200. At the same time, the support 310 abuts against the base 200 in the vertical direction to increase the shock resistance and stability of the central control screen 100 during the adjustment process.

[0041] Preferably, in order to further improve the smoothness of the adjustment process of the central control screen 100, two drive mechanisms 300 are set, and the two drive mechanisms 300 are arranged in parallel at both ends of the central control screen 100 in the horizontal direction. The bracket 4 is fixedly set with the central control screen 100 and the limiting hole 41 is located in the middle of the two sets of drive mechanisms 300. Preferably, the two drive mechanisms 300 are symmetrically arranged at both ends of the central control screen 100, and the limiting hole 41 is centrally located between the two sets of drive mechanisms 300.

[0042] The adjustable central control screen 100 mechanism involved in this embodiment also includes a control system that is telecommunicationly connected to the motor 320. The control system transmits the input signal from the input terminal to the control terminal, and the control terminal drives the motor 320 to rotate according to the received signal. The central control screen 100 is adjusted by controlling the working time and / or rotation speed of the motor 320. The telecommunication connection between the control system and the motor 320 can be achieved by those skilled in the art using existing technology. The input terminal includes, but is not limited to, the central control screen 100, buttons or knobs placed on the steering wheel, buttons or knobs placed on the interior trim panel, intelligent voice interaction, mobile terminals, etc.

[0043] In use, if the central control screen 100 needs to be adjusted, only a signal needs to be input at the input end of the control system, and then the control system drives the motor 320 to rotate. Since the cantilever 6 and the motor output shaft 321 are connected by a sliding screw, under the drive of the motor 320, the cantilever 6 can be infinitely adjusted to different extension lengths within its preset stroke range, pushing the central control screen 100 to extend forward or retract. When the central control screen 100 extends forward or retracts backward, the movement trajectory of the central control screen 100 is guided and restricted by the limit hole 41 and the connecting shaft 51, so that the central control screen 100 can rotate horizontally with the second hinge shaft 621 as the rotation axis when it extends forward or retracts backward, thereby realizing the angle adjustment. When the central control screen 100 is adjusted to the required position, the cooperation between the external thread of the motor output shaft 321 and the internal thread of the cantilever 6 end can achieve self-locking, avoiding the change of position of the central control screen 100 due to external interference, such as vibration during vehicle operation or touch by the user's body. Improve user comfort and driving safety when using the central control screen.

[0044] A second embodiment of the present invention relates to an adjustable central control screen mechanism. For example... Figure 6-10 As shown, in the second embodiment of the present invention, the adjustable central control screen 100 mechanism includes a central control screen 100, a base 200, and a drive mechanism 300 that is rotatably connected to the base 200 and the central control screen 100 respectively. A guide mechanism is provided connected to the base 200, and the guide mechanism is used to limit the movement trajectory of the central control screen 100.

[0045] The drive mechanism 300 includes a support 310 and a motor 320 fixedly mounted at one end of the support 310. The motor output shaft 321 of the motor 320 is positioned toward the central control screen 100. The one end is provided with a first connector 313, which is hinged to the base 200, so that the support 310 can rotate relative to the base 200 in the horizontal direction about the first hinge axis 3131. Preferably, the motor 320 is disposed between the sleeve 311 and the first connector 313. The drive mechanism 300 also includes a cantilever 6 that is connected to the motor output shaft 321 via a sliding screw drive. The motor output shaft 321 has an external thread, and the end of the cantilever 6 near the motor 320 has an internal thread that engages with the motor output shaft 321. The cantilever 6 and the motor output shaft 321 form a sliding screw drive connection, meaning that the cantilever 6 can perform axial extension and retraction under the rotation of the motor 320. The end of the cantilever 6 that engages with the motor output shaft 321 can be tapped using conventional machining methods. The cantilever 6 has a space extending axially along the internal thread inside, which is used to accommodate the screw drive stroke between the motor output shaft 321 and the cantilever 6. Alternatively, if there is reserved space for axial extension inside the cantilever 6, a nut can be fixedly installed at the end of the cantilever 6 that engages with the motor output shaft 321, and the sliding screw drive between the cantilever 6 and the motor output shaft 321 can be achieved through the thread engagement between the nut and the motor output shaft 321.

[0046] Preferably, a bracket 4 is fixedly provided at one end of the central control screen 100 facing the drive mechanism 300, and a second connector 62 is provided at the end of the cantilever 6 away from the motor 320. The second connector 62 is hinged to the bracket 4, so that the central control screen 100 and the cantilever 6 can rotate relative to each other in the horizontal direction about the second hinge axis 621.

[0047] The adjustable central control screen mechanism involved in this embodiment includes a first drive mechanism 301 and a second drive mechanism 302. The two drive mechanisms 300 have identical structures. The first drive mechanism 301 and the second drive mechanism 302 are arranged parallel to each other at both ends of the central control screen 100 in the horizontal direction. The guiding mechanism includes a connecting rod 7 disposed between the first drive mechanism 301 and the second drive mechanism 302. A guide post 71 is provided in the middle of the connecting rod 7 facing the base 200. A first guide groove 220 is provided at the corresponding position of the base 200. The guide post 71 and the first guide groove 220 are connected. With a sliding fit, the support 310 of the first drive mechanism 301300 is provided with a second guide groove 315. The second guide groove 315 is an elongated hole extending along the axial direction of the sleeve 311. One end of the connecting rod 7 is fixedly provided with a limiting part 72. The limiting part 72 is slidably disposed in the second guide groove 315. One end of the connecting rod 7 is rotatably disposed on the support 310 of the second drive mechanism 302300. During the extension and retraction of the cantilever 6, the movement trajectory of the central control screen 100 is guided and restricted through the interconnection between the connecting rod 7, the support 310, and the base 200.

[0048] Preferably, to increase the stability of the cantilever 6 during telescopic movement, the support 310 is provided with a hollow sleeve 311 extending along the direction of the motor output shaft 321, with the motor output shaft 321 facing the sleeve 311. The cantilever 6 is housed within the sleeve 311. Preferably, the motor output shaft 321 and the sleeve 311 are coaxially arranged. A limiting post 61 is fixedly provided at one end of the cantilever 6 near the motor output shaft 321. A limiting groove 31 adapted to the limiting post 61 extends axially along the side wall of the sleeve 311. 2. The limiting post 61 is slidably engaged with the limiting groove 312. The limiting post 61 slides within the limiting groove 312 as the cantilever 6 extends and retracts. The side wall of the limiting groove 312 limits the limiting post 61 in a direction perpendicular to the axial direction of the cantilever 6, making the axial extension and retraction of the cantilever 6 more stable and preventing the cantilever 6 from overturning during movement. Preferably, a bearing can also be sleeved on the limiting post 61. The limiting post 61 slides and engages with the limiting groove 312 through the bearing, making the extension and retraction of the cantilever 6 smoother.

[0049] To further improve the shock resistance and stability of the central control screen 100 during adjustment, a support column 314 is fixedly installed on the side wall of the support 310 facing the base 200. Preferably, the support column 314 is located directly below the sleeve 311. A corresponding groove 210 is provided on the base 200 to cooperate with the support column 314. The groove 210 is arc-shaped, and its specific shape can be set according to the position of the support column 314 and the movement trajectory of the support column 314 during the adjustment of the central control screen 100. Fasteners are also provided. The support column 314 is connected through the slide groove 210, so that the support 310 is stopped and limited by the base 200 in the axial direction. During the adjustment of the central control screen 100, the support column 314 slides in the slide groove 210. The support column 314 is stopped and limited by the base 200 in its axial direction. The support 310 can move horizontally relative to the base 200. At the same time, the support 310 abuts against the base 200 in the vertical direction to increase the shock resistance and stability of the central control screen 100 during the adjustment process.

[0050] The adjustable central control screen 100 mechanism involved in this embodiment also includes a control system that is telecommunicationly connected to the motor 320. The control system transmits the input signal from the input terminal to the control terminal, and the control terminal drives the motor 320 to rotate according to the received signal. The central control screen 100 is adjusted by controlling the working time and / or rotation speed of the motor 320. The telecommunication connection between the control system and the motor 320 can be achieved by those skilled in the art using existing technology. The input terminal includes, but is not limited to, the central control screen 100, buttons or knobs placed on the steering wheel, buttons or knobs placed on the interior trim panel, intelligent voice interaction, mobile terminals, etc.

[0051] The second embodiment is largely the same as the first embodiment, with the main difference being the different guiding mechanisms. In the first embodiment, when the cantilever 6 extends and retracts, it causes the central control screen 100 to shift. The central control screen 100 rotates around the connecting shaft 51 with the bracket 4 and slides along the length of the limiting hole 41, thereby restricting the movement trajectory of the central control screen 100 through the cooperation between the limiting hole 41 and the connecting shaft 51. In the second embodiment, the movement trajectory of the central control screen 100 is mainly restricted by the sliding cooperation between the guide post 71 of the connecting rod 7 and the first guide groove 220 provided on the base 200, and the sliding cooperation between the limiting part 72 of the connecting rod 7 and the second guide groove 315.

[0052] The third embodiment of the present invention relates to an adjustable central control screen 100 mechanism. For example... Figure 11-14As shown, in the third embodiment of the present invention, the adjustable central control screen 100 mechanism includes a central control screen 100, a base 200, and a drive mechanism 300 that is rotatably connected to the base 200 and the central control screen 100 respectively. A guide mechanism is provided connected to the base 200, and the guide mechanism is used to limit the movement trajectory of the central control screen 100.

[0053] The guiding mechanism includes a bracket 4 fixedly mounted on one end of the central control screen 100 facing the drive mechanism 300. A limiting hole 41 is provided through the middle of the bracket 4. The limiting hole 41 is an elongated hole. The bracket 4 is movably connected to the base 200 through a bushing 5. The bushing 5 includes a connecting shaft 51 and a connecting cap 52. The connecting shaft 51 of the bushing 5 passes through the limiting hole 41 and is fixedly mounted on the base 200. The connecting shaft 51 and the limiting hole 41 are in clearance fit. The bracket 4 can rotate around the connecting shaft 51 and slide along the length of the limiting hole 41. The diameter of the connecting cap 52 is larger than the width of the limiting hole 41, so that the connecting cap 52 stops on one side of the limiting hole 41.

[0054] The drive mechanism 300 includes a telescopic cylinder 800, which includes a cylinder sleeve 810 and a telescopic rod 820. One end of the cylinder sleeve 810 is rotatably connected to the base 200, and the other end is engaged with one end of the telescopic rod 820. One end of the telescopic rod 820 is slidably disposed inside the cylinder sleeve 810, and the other end is rotatably connected to the bracket 4 of the central control screen 100. Preferably, one end of the cylinder sleeve 810 is hinged to the base 200, and the telescopic cylinder 800 can rotate horizontally relative to the base 200. One end of the telescopic rod 820 is hinged to the bracket 4, and the telescopic rod 820 and the bracket 4 of the central control screen 100 can rotate horizontally relative to each other. Preferably, the cylinder liner 810 is provided with a guide groove 811, and the telescopic rod 820 is provided with a slider 821 that is adapted to the guide groove 811. When the telescopic rod 820 moves telescopically relative to the cylinder liner 810, the slider 821 slides with the guide groove 811. The guide groove 811 can guide the movement of the telescopic rod 820 in the axial direction, making the sliding fit between the telescopic rod 820 and the cylinder liner 810 more stable. Preferably, the cylinder liner 810 is provided with a support column 812 facing the base 200, and the base 200 is provided with a sliding groove 210 adapted to the support column 812. Fasteners are used to pass through the sliding groove 210 and fix them to the support column 812. The support column 812 and the sliding groove 210 are slidably engaged. The support column 812 is stopped and limited by the base 200 in its axial direction. The cylinder liner 810 can move horizontally relative to the base 200. At the same time, the cylinder liner 810 abuts against the base 200 in the vertical direction to increase the shock resistance and stability of the central control screen 100 during adjustment.

[0055] Preferably, the drive mechanism 300 further includes a support 310, one end of which is provided with a first connector 313. The support 310 is hinged to the base 200 through the first connector 313. The other end of the support 310 is provided with a hollow cylindrical sleeve 311. The cylinder liner 810 of the telescopic rod 820 is fixedly disposed at the end of the support 310 near the first connector 313. The telescopic rod 820 is housed in the sleeve 311. The end of the telescopic rod 820 is provided with a second connector 62, which is hinged to the bracket 4.

[0056] To increase the stability of the telescopic rod 820 during telescopic movement, a limiting groove 312 adapted to the guide groove 811 is provided on the side wall of the sleeve 311 along the axial direction. The guide groove 811 is accommodated in the limiting groove 312. The limiting groove 312 limits the guide groove 811 in a direction perpendicular to the axial direction of the telescopic cylinder 800 to prevent the telescopic rod 820 from overturning during movement.

[0057] To further enhance the shock resistance and stability of the central control screen 100 during adjustment, a support column 314 is fixedly installed on the side wall of the support 310 facing the base 200. Preferably, the support column 314 is located directly below the sleeve 311. A corresponding groove 210 is provided on the base 200 to cooperate with the support column 314. The groove 210 is arc-shaped, and its specific shape can be set according to the position of the support column 314 and the movement trajectory of the support column 314 during the adjustment of the central control screen 100. Fasteners pass through the groove 210 and connect with the support column 314, so that the support 310 is stopped and limited by the base 200 in the axial direction. During the adjustment of the central control screen 100, the support column 314 slides within the groove 210, and the support 310 can move horizontally relative to the base 200. At the same time, the support 310 abuts against the base 200 in the vertical direction to increase the shock resistance and stability of the central control screen 100 during adjustment.

[0058] Preferably, the central control screen 100 is provided with an ear to facilitate the user to adjust the position of the central control screen 100 by holding the ear.

[0059] In use, the central control screen 100 needs to be manually moved to move the telescopic rod 820. The central control screen 100 rotates around the connecting shaft 51 with the bracket 4 and slides along the length of the limiting hole 41. The movement trajectory of the central control screen 100 is restricted by the cooperation between the limiting hole 41 and the connecting shaft 51, thus completing the position adjustment of the central control screen 100. Controlling different extension lengths of the telescopic rod 820 allows for stepless adjustment of the central control screen 100 to any position within its travel range. By adjusting the damping of the telescopic rod, the central control screen 100 cannot be easily manually changed after being adjusted to a suitable position, achieving a good fixing effect. This improves user comfort and driving safety, and the structure is simple and durable.

[0060] The third embodiment is largely the same as the first embodiment, with the main difference being the driving mechanism 300. In the first embodiment, the driving mechanism 300 achieves position adjustment of the central control screen 100 through a sliding screw drive between the motor output shaft 321 and the cantilever 6. In the third embodiment, however, the driving mechanism 300 achieves position adjustment of the central control screen 100 through a sliding engagement between the cylinder liner 810 and the telescopic rod 820. Compared to the first embodiment, this method is more energy-efficient and environmentally friendly.

[0061] In summary, in the adjustable central control screen 100 mechanism of the present invention, the guide mechanism is used to limit the movement trajectory of the central control screen 100. In the first and third embodiments, the guide mechanism is a structure design in which a limiting hole 41 is provided on the bracket 4, the bracket 4 is connected to the base 200 through the limiting hole 41 and the bushing 5, the bracket 4 rotates around the connecting shaft 51 and slides along the length of the limiting hole 41, thereby limiting the movement trajectory of the central control screen 100 through the cooperation of the limiting hole 41 and the connecting shaft 51. In the second embodiment, the guide mechanism is a structure design in which a connecting rod 7 is provided between the drive mechanisms 300, the connecting rod 7 is provided with a guide post 71, and the movement trajectory of the central control screen 100 is limited through the mutual cooperation between the guide post 71 and the first guide groove 220 provided on the base 200 and the mutual cooperation between the limiting part 72 of the connecting rod 7 and the second guide groove 315.

[0062] The adjustable central control screen mechanism provided by this invention facilitates the adjustment of the central control screen position through the cooperation of the drive mechanism and the guide mechanism. The adjustment mechanism is stable and reliable, improving the comfort of the central control screen observation and driving safety. Through the sliding screw transmission between the motor output shaft and the cantilever, the central control screen can achieve stepless adjustment within the adjustable stroke range. The threaded drive mechanism allows the central control screen to be locked at any position within the stroke, achieving a good fixing effect. The design of the support column and the slide groove ensures that the support is supported and limited by the base in the vertical direction, giving the central control screen good shock resistance and stability during movement.

[0063] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of the present invention.
