Description

Technical Field

[0001] The utility model relates to the technical field of display screen deflection, and more specifically, to a display screen deflection mechanism. Background Art

[0002] With the rapid rise of the new energy vehicle industry, in-vehicle central control display screens, as an important part of intelligent connected vehicles, have increasingly higher requirements for their design and functional needs. The motion mechanisms of traditional central control display screens mostly adopt the fixed-axis rotation method. Although this design is simple, its functions are single and cannot meet users' pursuit of diverse display angles and personalized operation experiences. At the same time, the fixed-axis rotation design often imposes certain restrictions on the overall vehicle styling, requiring interior designers to avoid the rotation envelope of the display screen during styling design, thus affecting the overall aesthetic sense and coordination of the interior design. Content of the Utility Model

[0003] The purpose of the utility model is to provide a display screen deflection mechanism. By providing power through a driving component, using a transmission structure and a guiding connecting piece to convert the power into a linear motion along a second direction, and through the interaction of a rotating shaft component, a first guiding groove, and a second guiding groove, the multi-angle and multi-direction deflection of the display screen is realized. At the same time, the structure of the utility model is compact and easy to install, and it can be well integrated into the overall vehicle interior design without damaging the overall vehicle styling.

[0004] A display screen deflection mechanism includes a driving component, a rotating shaft component, a mounting base, and a fixing bracket for mounting the display screen. The rotating shaft component is movably arranged on the mounting base. The mounting base is provided with a first guiding groove. One end of the fixing bracket is rotatably connected to the mounting base through the rotating shaft component, and the other end forms a sliding end extending into the first guiding groove. The fixing bracket is provided with a second guiding groove along a first direction. The driving component includes a transmission structure and a guiding connecting piece. The guiding connecting piece extends into the second guiding groove. The transmission structure drives the guiding connecting piece to perform a linear motion along a second direction. The guiding connecting piece pushes the fixing bracket through the groove wall of the second guiding groove to make the sliding end move along the first guiding groove, so as to realize the deflection of the fixing bracket. The first direction is perpendicular to the second direction.

[0005] In the above technical solution, when the display deflection mechanism is not activated, the fixed bracket is in a certain initial position, its sliding end extends into the first guide groove of the mounting base, and the guide connecting member extends into the second guide groove of the fixed bracket. When it is necessary to adjust the angle of the display, the drive assembly starts to work. The transmission structure receives power from the outside (such as a motor) and starts to perform a linear motion along the second direction (perpendicular to the first direction). As the transmission structure moves, the guide connecting member also moves along the second direction. During the movement, the guide connecting member contacts the groove wall of the second guide groove and pushes it. Due to the linear motion of the guide connecting member along the second direction and the generation of a thrust perpendicular to the second direction on the fixed bracket through the second guide groove, this thrust causes the sliding end of the fixed bracket to start moving along the first guide groove. Since one end of the fixed bracket is connected to the mounting base through a rotating shaft assembly, this movement causes the fixed bracket to deflect around the rotating shaft assembly. As the fixed bracket deflects, the display mounted on the fixed bracket will also correspondingly change its orientation and angle, thus meeting the viewing needs of users in different scenarios. The utility model provides power through the drive assembly, uses the transmission structure and the guide connecting member to convert the power into a linear motion along the second direction, and realizes the multi-angle and multi-direction deflection of the display through the interaction of the rotating shaft assembly, the first guide groove and the second guide groove. At the same time, the structure of the utility model is compact and easy to install, and can be well integrated into the interior design of the whole vehicle without damaging the shape of the whole vehicle.

[0006] Further, the first guide groove includes a first groove section and a second groove section communicating with the first groove section, and an included angle is formed between the first groove section and the second groove section.

[0007] In the above technical solution, when the drive assembly generates a driving force, the guide connecting member moves along the first groove section or the second groove section, thereby realizing the deflection of the display. By adjusting the included angle between the first groove section and the second groove section, the deflection angle range of the fixed bracket can be flexibly adjusted. This design enables the mechanism to adapt to different requirements for the display angle in different application scenarios.

[0008] Further, the rotating shaft assembly includes a slide rail, a slider and a rotating shaft. The slide rail is arranged on the mounting base and extends along the first direction. The slider is slidably arranged on the slide rail. The rotating shaft is arranged on the slider and is rotatably connected to the fixed bracket.

[0009] In the above technical solution, when the fixed bracket deflects, the slider moves on the slide rail and drives the rotating shaft and the fixed bracket to move together, avoiding unnecessary offset or distortion. The rotational connection between the rotating shaft and the fixed bracket enables the fixed bracket to rotate relative to the slider within a certain range. This design allows the display screen to translate along the direction of the slide rail and rotate around the rotating shaft during deflection, thus realizing a more complex and flexible deflection mechanism.

[0010] Further, at least one guide wheel is provided on the slider, a chute is provided on the fixed bracket, the chute is perpendicular to the first direction, and the guide wheel extends into the chute.

[0011] In the above technical solution, when the driving component starts to work, it pushes the fixed bracket to deflect through the guiding connecting piece, the first guiding groove and the second guiding groove. During this process, the guide wheel on the slider moves along the direction of the chute. This translational movement is combined with the rotational movement of the fixed bracket around the rotating shaft to jointly realize the deflection of the display screen.

[0012] Further, the sliding end is a damping structure, and the damping structure includes a damping shaft, and a first gasket, a second gasket and an elastic sheet sleeved on the outer periphery of the damping shaft. One end of the damping shaft is connected to the fixed bracket, and the other end passes through the first guiding groove. The first guiding groove is located between the first gasket and the second gasket, one end of the elastic sheet abuts against the damping shaft, and the other end abuts against the first gasket.

[0013] In the above technical solution, the damping shaft passes through the first guiding groove, and the first gasket and the second gasket are respectively located on both sides of the first guiding groove. Therefore, the damping shaft will generate frictional force with the first gasket and the second gasket during movement. This frictional force constitutes the damping effect, which can slow down the moving speed of the fixed bracket and make the display screen more stable during deflection. At the same time, the elastic force provided by the elastic sheet ensures that the damping shaft can maintain close contact with the gasket during movement, thus maintaining a stable damping effect.

[0014] Further, the transmission structure includes a driving member and a lead screw assembly. The lead screw assembly includes a lead screw and a nut. The guiding connecting piece is connected to the nut, and the driving member drives the nut to move along the lead screw to drive the guiding connecting piece to perform a linear motion along the second direction.

[0015] In the above technical solution, when the driving member starts to work, it drives the lead screw to rotate through its output shaft or transmission shaft. When the lead screw rotates, the nut matched with it moves linearly along the lead screw. The guiding connecting piece is connected to the nut, so when the nut moves, the guiding connecting piece also moves accordingly.

[0016] Further, the transmission structure further includes at least one guide rod, the guide rod is arranged in parallel with the lead screw, and the guide connecting member is slidably connected to the guide rod.

[0017] In the above technical solution, the guide connecting member is slidably connected to the guide rod, which means that during the movement of the guide connecting member, it will slide along the guide rod, thereby maintaining the stability and accuracy of its movement trajectory. The design of the guide rod not only provides additional support for the guide connecting member, but also restricts its lateral displacement during movement, further improving the stability and precision of the deflection mechanism.

[0018] Further, the guide connecting member is provided with a groove, and the guide rod is inserted through the groove.

[0019] In the above technical solution, the cooperation between the groove and the guide rod enables the guide connecting member to obtain stable support during movement, thereby maintaining the stability and accuracy of its movement trajectory.

[0020] Compared with the prior art, the beneficial effect of the present utility model is that by designing the rotating shaft assembly, the first guide groove and the second guide groove, when the driving member drives the guide connecting member to move linearly along the second direction, the guide connecting member comes into contact with the groove wall of the second guide groove and pushes it, causing the sliding end of the fixed bracket to start moving along the first guide groove, thereby realizing the deflection of the fixed bracket and further realizing the deflection of the display screen.

[0033] The deflection mechanism of the display screen of the present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] Please refer to Figures 1 to 4 , in a preferred embodiment, the deflection mechanism of the display screen of the present utility model includes a driving assembly 1, a rotating shaft assembly 2, a mounting base 3, and a fixed bracket 5 for mounting the display screen 4. The rotating shaft assembly 2 is movably arranged on the mounting base 3. The mounting base 3 is provided with a first guide groove 301. One end of the fixed bracket 5 is rotatably connected to the mounting base 3 through the rotating shaft assembly 2, and the other end forms a sliding end 6 extending into the first guide groove 301. The fixed bracket 5 is provided with a second guide groove 501 along the first direction. The driving assembly 1 includes a transmission structure 101 and a guide connecting piece 102. The guide connecting piece 102 extends into the second guide groove 501. The transmission structure 101 drives the guide connecting piece 102 to move linearly along the second direction. The guide connecting piece 102 pushes the fixed bracket 5 through the groove wall of the second guide groove 501 to make the sliding end 6 move along the first guide groove 301, so as to realize the deflection of the fixed bracket 5. The first direction is perpendicular to the second direction.

[0035] As can be seen from the above technical solution, when the display deflection mechanism is not activated, the fixed bracket 5 is in a certain initial position, its sliding end 6 extends into the first guiding groove 301 of the mounting base 3, and the guiding connecting member 102 extends into the second guiding groove 501 of the fixed bracket 5. When the angle of the display needs to be adjusted, the driving assembly 1 starts to work. The transmission structure 101 receives power from the outside (such as a motor) and starts to move linearly in the second direction (perpendicular to the first direction). As the transmission structure 101 moves, the guiding connecting member 102 also moves in the second direction. During the movement, the guiding connecting member 102 comes into contact with the groove wall of the second guiding groove 501 and pushes it. Due to the linear movement of the guiding connecting member 102 in the second direction and the generation of a thrust perpendicular to the second direction on the fixed bracket 5 through the second guiding groove 501, this thrust causes the sliding end 6 of the fixed bracket 5 to start moving along the first guiding groove 301. Since one end of the fixed bracket 5 is connected to the mounting base 3 through the rotating shaft assembly 2, this movement causes the fixed bracket 5 to deflect around the rotating shaft assembly 2. As the fixed bracket 5 deflects, the display mounted on the fixed bracket 5 will correspondingly change its orientation and angle, thus meeting the viewing needs of users in different scenarios. The utility model provides power through the driving assembly 1, converts the power into a linear movement in the second direction by using the transmission structure 101 and the guiding connecting member 102, and realizes the multi-angle and multi-direction deflection of the display through the interaction of the rotating shaft assembly 2, the first guiding groove 301 and the second guiding groove 501. At the same time, the structure of the utility model is compact and easy to install, can be well integrated into the interior design of the whole vehicle, and will not damage the shape of the whole vehicle.

[0036] Specifically, the first guiding groove 301 includes a first groove section 3011 and a second groove section 3012 communicating with the first groove section 3011, and an included angle is formed between the first groove section 3011 and the second groove section 3012. When the driving assembly 1 generates a driving force, the guiding connecting member 102 moves along the first groove section 3011 or the second groove section 3012, thereby realizing the deflection of the display. By adjusting the size of the included angle between the first groove section 3011 and the second groove section 3012, the deflection angle range of the fixed bracket 5 can be flexibly adjusted. This design enables the mechanism to adapt to different requirements for the display angle in different application scenarios. Moreover, since the first groove section 3011 and the second groove section 3012 are communicating and a smooth included angle is formed between them, the fixed bracket 5 can achieve a smooth transition when moving from one groove section to the other. This smooth transition helps to reduce the impact and vibration during movement, and improve the stability and durability of the mechanism. The included angle design can optimize the space utilization to a certain extent. For example, in some application scenarios, it may be necessary to deflect the display 4 to a specific angle to avoid obstacles or improve the viewing effect. By adjusting the size of the included angle, this goal can be achieved without increasing the overall size of the mechanism.

[0037] Please refer to Figure 4 , the rotating shaft assembly 2 includes a slide rail 201, a slider 202 and a rotating shaft 203. The slide rail 201 is arranged on the mounting base 3 and extends along the first direction. The slider 202 is slidably arranged on the slide rail 201. The rotating shaft 203 is arranged on the slider 202 and is rotatably connected to the fixed bracket 5. When the fixed bracket 5 deflects, the slider 202 moves on the slide rail 201 and drives the rotating shaft 203 and the fixed bracket 5 to move together, avoiding unnecessary offset or distortion. The rotational connection between the rotating shaft 203 and the fixed bracket 5 allows the fixed bracket 5 to rotate relative to the slider 202 within a certain range. This design allows the display screen to translate along the direction of the slide rail 201 and rotate around the rotating shaft 203 during deflection, thus realizing a more complex and flexible deflection mechanism

[0038] Meanwhile, at least one guide wheel 204 is arranged on the slider 202, and the fixed bracket 5 is provided with a chute 502. The chute 502 is perpendicular to the first direction, and the guide wheel 204 extends into the chute 502. When the driving assembly 1 starts to work, it will push the fixed bracket 5 to deflect through the guide connecting piece 102, the first guide groove 301 and the second guide groove 501. During this process, the guide wheel 204 on the slider 202 will move along the direction of the chute 502. This translational movement is combined with the rotational movement of the fixed bracket 5 around the rotating shaft to jointly realize the deflection of the display screen. The movement of the guide wheel 204 in the chute 502 not only ensures the stability of the deflection of the fixed bracket 5, but also restricts its lateral movement during deflection, thereby improving the accuracy of deflection.

[0039] Please refer to Figure 5, the sliding end 6 is a damping structure, which includes a damping shaft 601, a first gasket 602, a second gasket 603 and a spring piece 604 sleeved on the outer periphery of the damping shaft 601. One end of the damping shaft 601 is connected to the fixed bracket 5, and the other end passes through the first guide groove 301. The first guide groove 301 is located between the first gasket 602 and the second gasket 603. One end of the spring piece 603 abuts against the damping shaft 601, and the other end abuts against the first gasket 602. The damping shaft 601 passes through the first guide groove 301, and the first gasket 602 and the second gasket 603 are respectively located on both sides of the first guide groove 301. Therefore, the damping shaft 601 will generate frictional force with the first gasket 602 and the second gasket 603 during the movement process. This frictional force constitutes the damping effect, which can slow down the movement speed of the fixed bracket 5 and make the display screen more stable during the deflection process. At the same time, the elastic force provided by the spring piece 603 ensures that the damping shaft 601 can maintain close contact with the gasket during the movement process, thereby maintaining a stable damping effect. Even when the external environment (such as temperature, humidity) changes cause the material to expand or contract, the spring piece 603 can also play a compensatory role to maintain the stability of the damping structure.

[0040] Please refer to again Figure 3 , the transmission structure 101 includes a driving member 1011 and a lead screw assembly 1012. The lead screw assembly 1012 includes a lead screw 1012a and a nut 1012b. The guiding connecting member 102 is connected to the nut 1012b. The driving member 1011 drives the nut 1012b to move along the lead screw 1012a to drive the guiding connecting member 102 to move in a straight line in the second direction. When the driving member 1011 starts to work, it will drive the lead screw 1012a to rotate through its output shaft or transmission shaft. When the lead screw 1012a rotates, the nut 1012b that matches it will move in a straight line along the lead screw 1012a. The guiding connecting member 102 is connected to the nut 1012b. Therefore, when the nut 1012b moves, the guiding connecting member 102 will also move accordingly. During the movement process, the guiding connecting member 102 comes into contact with the groove wall of the second guide groove 501 and pushes it, thereby driving the sliding end 6 of the fixed bracket 5 to start moving along the first guide groove 301.

[0041] In addition, the transmission structure 101 further includes at least one guide rod 1013. The guide rod 1013 is arranged parallel to the lead screw 1012a, and the guiding connecting member 102 is slidably connected to the guide rod 1013. The guiding connecting member 102 is slidably connected to the guide rod 1013, which means that during the movement process of the guiding connecting member 102, it will slide along the guide rod 1013, thereby maintaining the stability and accuracy of its movement trajectory. The design of the guide rod 1013 not only provides additional support for the guiding connecting member 102, but also limits its lateral displacement during the movement process, further improving the stability and precision of the deflection mechanism.

[0042] It should be noted that the guiding connecting member 102 is provided with a groove 1021, and the guiding rod 1013 is inserted into the groove 1021. The cooperation between the groove 1021 and the guiding rod 1013 enables the guiding connecting member 102 to be stably supported during movement, thereby maintaining the stability and accuracy of its movement trajectory.
