Description

Technical Field

[0001] This application relates to the technical field of azimuth adjustment, and particularly to an azimuth adjuster, a display terminal, and a vehicle. Background Art

[0002] With the development of automotive intelligence, in-vehicle center control screens have become the core of interaction integrating functions such as multimedia, intelligent driving, and vehicle networking. However, fixed screens have pain points such as viewing angle adjustment defects and reflection interference, making it difficult to adapt to the personalized needs of users. Research has found that the pitching deviation of the visible comfort zone for drivers of different heights reaches ±25°, and the visual experience deteriorates even more due to the change of day and night lighting.

[0003] Most of the existing in-vehicle center control screen angle adjustment schemes can only achieve the deflection angle adjustment at a fixed position (such as the up, down, left, and right deflection adjustments), and a small number can achieve the deflection angle adjustment plus rotation adjustment at a fixed position, but this correspondingly increases the structural complexity of the adjustment device, occupies a large space, and has a high cost. Therefore, there is an urgent need to develop an adjustment device that can omnidirectionally adjust the angle of the in-vehicle center control screen and has a simple and compact structure. Summary of the Invention

[0004] In view of the above, it is necessary to provide an azimuth adjuster, a display terminal, and a vehicle, which can achieve the three-dimensional omnidirectional adjustment of the display terminal, and have a simple and compact structure, and can improve the structural layout efficiency in a limited space.

[0005] The first aspect of this application provides an azimuth adjuster for the azimuth adjustment of a display terminal, including an adjustment component and a support component.

One end of the support component is connected to the display terminal in a universal manner, and the other end of the support component is a fixed end. At least part of the support component can revolve around the first axis and drive the adjustment component to revolve around the first axis. At least part of the adjustment component can rotate around the second axis and drive at least another part of the adjustment component to move along the second axis.

When the adjustment assembly is fixedly connected to the display terminal, the rotation of the adjustment assembly driven by the support assembly can realize the rotational adjustment of the display terminal. When the adjustment assembly is movably connected to the display terminal, the rotation of the adjustment assembly driven by the support assembly can realize the change of the connection position between the adjustment assembly and the display terminal, and then the deflection angle of the display terminal can be adjusted by the movement of the adjustment assembly in the direction of the second axis. The orientation adjuster of the present application can realize the three-dimensional omnidirectional angle adjustment of the display terminal only through the synergistic effect of two mechanisms, namely the support assembly and the adjustment assembly.

[0031] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific embodiments

[0034] In addition, it should be noted that the terms "first" and "second" in the specification, claims, and drawings of this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0035] With the continuous development of automotive intelligent technologies, the in-vehicle center control screen has become the core interactive interface for vehicle function control. Modern automotive center control systems not only need to integrate conventional functions such as multimedia control, digital instrument display, navigation guidance, and rearview imaging, but also gradually expand to diversified fields such as intelligent driving assistance, vehicle networking services, and personalized settings. Against the background of a substantial increase in the usage frequency of the center control screen, the perspective adjustment defects of traditional fixed screens have gradually become an important technical bottleneck affecting the user experience.

[0036] Currently, there are mainly two technical routes for the installation technology of in-vehicle center control screens. The mainstream solution adopts a structural design that directly fixes the screen to the instrument panel. Although it ensures the structural stability, it cannot meet the individualized needs of drivers and passengers. Ergonomic experimental data shows that there is a pitch deviation of ±25° in the visual comfort zone of drivers of different heights, and the day-night light changes in the in-vehicle environment will cause obvious reflection interference on the fixed screen. Although the existing mechanical adjustment solutions can partially alleviate the above problems, there are still significant technical limitations: Although the conventional manual adjustment bracket can realize the horizontal / vertical conversion of the screen and a small range of translation, the adjustment process requires interrupting the driving operation, seriously affecting driving safety; Although some electric adjustment devices can realize the automatic adjustment of the pitch angle within a preset angle range, there are technical defects such as insufficient transmission accuracy and motion lag in the dual-axis adjustment mechanism.

[0037] More notably, a series of structural contradictions have emerged in the existing high-order adjustment devices during the implementation of multi-dimensional adaptive adjustment: First, the three-dimensional adjustment mechanism generally adopts a composite structure of multi-stage gear sets and linkage rods, resulting in a 35%-60% increase in the product thickness or a complex structure, making it difficult to adapt to the limited space layout of the instrument panel; Second, the side link assembly will generate a visual occlusion area during the forward tilting and flipping process of the screen, and it is easy to form a blind area range of 80-150 mm during operations that require a downward viewing angle such as vehicle parking, seriously affecting parking.

[0038] Therefore, the embodiments of the present application provide an azimuth regulator, a display terminal, and a vehicle, which can realize the three-dimensional omnidirectional adjustment of the display terminal, and have a simple structure, can improve the structural layout efficiency in a limited space, and can reduce the limitation of the traditional adjustment mechanism that is prone to generate visual blind areas. Some embodiments will be described below with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] Figure 1 It is a schematic diagram of the application scenario of the azimuth regulator 1 in the embodiments of the present application. Figure 2 It is a schematic diagram of the structure of the display terminal 2 in the embodiments of the present application. Figure 3 It is a schematic diagram of the structure of the azimuth regulator 1 in the embodiments of the present application.

[0040] The embodiments of the present application first provide an azimuth regulator 1, which can be used for the azimuth adjustment of the display terminal 2. The display terminal 2 can specifically refer to any electronic device for presenting visual information, and can include but not limited to at least one of LCD, OLED, Mini-LED, Micro-LED, or E-Ink displays.

[0041] Please refer to Figure 3 , the azimuth regulator 1 in the embodiments of the present application can include an adjustment component 11 and a support component 12, and the adjustment component 11 is connected to the support component 12. Among them, the adjustment component 11 can be used for adjusting the deflection angle of the display terminal 2 in a linear direction, and the support component 12 can be used for adjusting the rotation angle of the display terminal 2 in a plane. The combination of the adjustment component 11 and the support component 12 can enable the display terminal 2 to be adjusted with multiple degrees of freedom within a large range, meeting different usage requirements of users.

[0042] In the embodiments of the present application, one end of the adjustment component 11 is fixedly connected or movably connected to the annular guiding portion 21 of the display terminal 2. One end of the support component 12 is universally connected to the display terminal 2, and the other end is a fixed end. Specifically, one end of the support component 12 is movably connected to the universal connector 22 of the display terminal 2. That is, as Figure 2As shown, a circular guiding portion 21 and a universal connector 22 can be designed on the display terminal 2. The circular guiding portion 21 is used to connect with one end of the adjusting component 11, and the universal connector 22 is used to connect with one end of the supporting component 12. Specifically, the display terminal 2 can have an interface for display and a back surface opposite to the interface, and the circular guiding portion 21 and the universal connector 22 can be arranged on the back surface of the display terminal 2. "Movable connection" can mean that one end of the adjusting component 11 is connected to the circular guiding portion 21 through a specific mechanical structure (such as a sliding block, a bearing, etc.), so that the adjusting component 11 can move along the circular guiding portion 21.

[0043] In some embodiments, the circular guiding portion 21 can be a circular groove or a circular protrusion, and the shape of the circular guiding portion 21 can be circular, oval or other shapes that can be set for adjusting the orientation.

[0044] In some embodiments, one end of the adjusting component 11 connected to the circular guiding portion 21 can be configured to be lockable to the circular guiding portion 21, that is, one end of the adjusting component 11 connected to the circular guiding portion 21 is configured to lock or unlock the circular guiding portion 21. Specifically, when the adjusting component 11 locks the circular guiding portion 21, the adjusting component 11 is fixedly connected to the circular guiding portion 21. When the adjusting component 11 unlocks the circular guiding portion 21, the adjusting component 11 is movably connected to the circular guiding portion 21. In this case, when the orientation of the display terminal 2 is adjusted in place or needs to be flipped during the adjustment process, the stability after adjustment can be improved or the flipping of the display terminal 2 can be realized by locking and fixing the adjusting component 11 and the circular guiding portion 21.

[0045] In some embodiments, the adjusting component 11 can have a second axis, and at least a part of the adjusting component 11 can rotate around the second axis and drive at least another part of the adjusting component 11 to move along the second axis. The part of the adjusting component 11 that can move along the second axis is connected to the display terminal 2. When at least a part of the adjusting component 11 rotates around the second axis, at least another part of the adjusting component 11 can perform a linear movement and then drive a part of the display terminal 2 to move along the second axis, thereby realizing the angular deflection of the display terminal 2 in the first direction, and the first direction is the direction in which the second axis extends. That is, the rotational movement of at least a part of the adjusting component 11 can be converted into the linear movement of at least another part of the adjusting component 11, so as to realize the adjustment of the angular deflection of the display terminal 2 in the first direction.

[0046] In some embodiments, the support assembly 12 may have a first axis, and at least a part of the support assembly 12 can revolve around the first axis and drive the adjustment assembly 11 to revolve around the first axis. When a part of the support assembly 12 revolves around the first axis, the adjustment assembly 11 is driven to rotate synchronously with the support assembly 12, whereby the rotation angle of the display terminal 2 in the first plane can be further adjusted or the connection position between the adjustment assembly 11 and the display terminal 2 can be adjusted. The first plane is the rotation plane of the adjustment assembly 11. Specifically, a universal connector 22 is designed on the display terminal 2 for connecting to one end of the support assembly 12. The end of the support assembly 12 connected to the universal connector 22 may have a receiving cavity adapted to the shape of the universal connector 22. The receiving cavity and the universal connector 22 form a universal joint type coupling structure, enabling the display terminal 2 to rotate relative to the support assembly 12 in multiple directions. That is, the universal joint type coupling structure allows the display terminal 2 to perform multi-axis rotation within a larger range, thus providing more flexible support and adjustment capabilities. At the same time, since one end of the adjustment assembly 11 can be fixedly or movably connected to the annular guide portion 21 of the display terminal 2. When the two are fixedly connected, the rotation of the support assembly 12 will drive the adjustment assembly 11 to rotate and further cause the display terminal 2 to rotate within the rotation plane, thereby realizing the adjustment of the rotation angle of the display terminal 2 in the first plane. When the two are movably connected, the rotation of the support assembly 12 will drive the adjustment assembly 11 to slide along the annular guide portion 21 and change the connection position between the adjustment assembly 11 and the display terminal 2, so that the adjustment assembly 11 can adjust the deflection angle of the display terminal 2 at any position of the display terminal 2.

[0047] For the orientation adjuster of the present application, by providing the adjustment assembly 11 and the support assembly 12, the support assembly 12 is used for universal connection with the display terminal 2 and drives the adjustment assembly 11 to revolve around the first axis. The adjustment assembly 11 is used for fixedly or movably connecting with the display terminal 2 and can move along the second axis. When the adjustment assembly 11 is fixedly connected to the display terminal 2, the rotation of the display terminal 2 can be realized by driving the adjustment assembly 11 to rotate through the support assembly 12. When the adjustment assembly 11 is movably connected to the display terminal 2, the rotation of the display terminal 2 can be realized by driving the adjustment assembly 11 to rotate through the support assembly 12, thereby changing the connection position between the adjustment assembly 11 and the display terminal 2. Furthermore, the deflection angle of the display terminal 2 can be adjusted by the movement of the adjustment assembly 11 in the second axis direction. The orientation adjuster of the present application can realize the three-dimensional omnidirectional angle adjustment of the display terminal 2 only through the synergistic effect of the two mechanisms of the support assembly 12 and the adjustment assembly 11. The overall structure is simple and occupies little space, which can improve the structural layout efficiency in a limited space.

[0048] In some embodiments, please refer to Figure 5 and Figure 6, the azimuth adjuster 1 further includes a connecting housing 13. The adjusting assembly 11 and the supporting assembly 12 are disposed in the connecting housing 13 and connected through the connecting housing 13. The connecting housing 13 can rotate synchronously with the adjusting assembly 11 about the first axis. On the one hand, the connecting housing 13 can serve as a medium for the coordinated action between the adjusting assembly 11 and the supporting assembly 12. On the other hand, by accommodating the adjusting assembly 11 and the supporting assembly 12, it can protect the two and also improve the aesthetics.

[0049] In some embodiments, please refer to Figure 3 , the adjusting assembly 11 may include a first driving motor 111, a first transmission mechanism, and a telescopic shaft body 113. The first driving motor 111 is drivingly connected to the first transmission mechanism. The first transmission mechanism is threadedly connected to the telescopic shaft body 113. The axis of the telescopic shaft body 113 is the second axis. The first driving motor 111 can drive the first transmission mechanism to rotate. When the first driving motor 111 drives the first transmission mechanism to rotate, the telescopic shaft body 113 moves along the second axis. One end of the telescopic shaft body 113 is connected to the annular guiding portion 21. The first driving motor 111 is connected to the connecting housing 13.

[0050] In some embodiments, please refer to Figure 3 , the first transmission mechanism may include a first worm gear 112 and a first worm 1111. The first driving motor 111 is drivingly connected to the first worm 1111. The first worm 1111 meshes with the first worm gear 112. The first worm gear 112 is sleeved on the telescopic shaft body 113 through a thread 1131. In this case, the first driving motor 111 drives the first worm gear 112 to rotate about the second axis through the first worm 1111. When the first worm gear 112 rotates, it can cooperate with the thread 1131 to make the telescopic shaft body 113 perform a telescopic linear motion along the second axis. When the telescopic shaft body 113 moves, it can drive the display terminal 2 to move along the second axis. Thus, by converting the rotational motion of the first worm gear 112 into the telescopic linear motion of the telescopic shaft body 113, the angle deflection adjustment of the display terminal 2 in the first direction can be realized. In addition, the self-locking characteristic of the worm and worm gear further ensures that the position is automatically fixed when the adjustment ends, and the slip problem of traditional manual adjustment can be reduced.

[0051] In other embodiments, the first transmission mechanism may also include a first gear and a second gear. The first driving motor 111 is drivingly connected to the first gear. The first gear meshes with the second gear. The second gear has a threaded hole, and the second gear is sleeved on the telescopic shaft body 113 through a thread.

[0052] In some embodiments, the first worm gear 112 can be limited by the connecting housing 13. For example, the first worm gear 112 can be installed in the connecting housing 13 through angular contact bearings, axially fixed by thrust washers, and only the rotational freedom is retained. This can reduce the problem of poor displacement accuracy of the telescopic shaft body 113 caused by the axial movement of the first worm gear 112.

[0053] In some embodiments, the first driving motor 111 can include, but is not limited to, at least one of a DC motor, an AC motor, a stepper motor, a servo motor, or a switched reluctance motor.

[0054] In some embodiments, refer to Figure 3 , the support assembly 12 can include a coupling portion 122, a second driving motor 121, a second transmission mechanism, and a support shaft body 124. The second driving motor 121 is drivingly connected to the second transmission mechanism, the second transmission mechanism is fixedly connected to the support shaft body 124, the axis of the support shaft body 124 is the first axis. When the second driving motor 121 drives the second transmission mechanism, the second driving motor 121 revolves around the first axis. The coupling portion 122 is disposed at one end of the support shaft body 124 close to the display terminal 2 and is universally connected to the display terminal 2. The second driving motor 121 is connected to the connecting housing 13.

[0055] In some embodiments, refer to Figure 3, the second transmission mechanism may include a second worm gear 123 and a second worm 1211. The second driving motor 121 is in transmission connection with the second worm 1211. The second worm 1211 meshes with the second worm gear 123, and the second worm gear 123 is fixedly connected to the support shaft body 124. The coupling part 122 may be formed with a receiving cavity for receiving the universal connector 22, or the coupling part 122 may be a protruding structure, and the universal connector 22 is formed with a receiving cavity for receiving the coupling part 122. One end of the support shaft body 124 away from the display terminal 2 is a fixed end fixedly connected to the instrument panel 3 of the vehicle. Since the support shaft body 124 is fixedly connected to the instrument panel 3 and remains stationary, the second worm gear 123 also remains stationary. When the second driving motor 121 drives the second worm 1211 to rotate, due to the meshing of the second worm 1211 and the second worm gear 123, the second driving motor 121 and the second worm 1211 will revolve around the first axis. The connection of the second driving motor 121 to the connection housing 13 will further drive the connection housing 13 and the adjustment assembly 11 to revolve around the first axis. When the adjustment assembly 11 is movably connected to the display terminal 2, the rotational movement of the support assembly 12 causes the adjustment assembly 11 to slide along the annular guiding portion 21 to change the connection position between the adjustment assembly 11 and the display terminal 2; when the adjustment assembly 11 slides to the target connection position, it can be fixedly connected to the display terminal 2 by locking the annular guiding portion 21. At this time, the rotational movement of the support assembly 12 will cause the adjustment assembly 11 to drive the display terminal 2 to rotate in the first plane, thereby realizing the vertical and horizontal screen flipping adjustment of the display terminal 2. In cooperation with the linear movement of the adjustment assembly 11 in the first direction, the deflection angle of the display terminal 2 can be further adjusted. Among them, the first direction forms a preset angle with the first plane, and the preset angle can be 90°, 85° or 80°, which can be specifically adjusted according to actual needs and is not limited here. Through the cooperation of the support assembly 12 and the adjustment assembly 11, the plane rotation (around the first axis) and the spatial tilt angle (universal joint) of the display terminal 2 can be coordinately adjusted, thereby adapting to the viewing angle requirements of users in various dynamic environments of the vehicle. At the same time, since the support assembly 12 and the adjustment assembly 11 only achieve the direction and angle adjustment of the display terminal 2 through a single-stage gear transmission, without complex multi-stage transmission devices or multi-link mechanisms, the structure of the azimuth adjuster 1 is compact and occupies a small space. It is arranged on the back of the display terminal 2 and can be completely blocked by the display terminal 2, without affecting the user's line of sight and the aesthetics inside the vehicle.

[0056] In some other embodiments, the second transmission mechanism may also include a third gear and a fourth gear. The second driving motor 121 is in transmission connection with the third gear. The third gear meshes with the fourth gear, and the fourth gear is fixedly connected to the support shaft body.

[0057] In some embodiments, the first axis and the second axis are arranged in parallel, whereby the linear movement direction of the adjusting assembly 11 is perpendicular to the rotation plane of the adjusting assembly 11. The adjusting assembly 11 can achieve a large axial displacement in the direction of the second axis with a relatively small size setting, so as to make the deflection angle adjustment range of the display terminal 2 larger while ensuring spatial compactness.

[0058] In some embodiments, one end of the support assembly 12 away from the display terminal 2 is fixedly connected to the instrument panel 3 of the vehicle, that is, the fixed end of the support shaft body 124 is fixedly connected to the instrument panel 3 of the vehicle. Fixing the other end of the support assembly 12 to the vehicle instrument panel 3 provides a rigid mounting foundation for the azimuth adjuster 1, which can solve the problem of view angle deviation caused by the shaking of the existing in-vehicle display and ensure the adjustment stability during dynamic driving.

[0059] In some embodiments, the second driving motor 121 may include, but is not limited to, at least one of a DC motor, an AC motor, a stepper motor, a servo motor, or a switched reluctance motor.

[0060] Figure 4 is a schematic structural diagram of the claw mechanism 114 of the embodiment of the present application.

[0061] In some embodiments, please refer to Figure 3 and Figure 4 , the adjusting assembly 11 may further include a claw mechanism 114, and the claw mechanism 114 may be disposed on the telescopic shaft body 113. Specifically, the claw mechanism 114 is disposed at one end of the telescopic shaft body 113 close to the display terminal 2, and the claw mechanism 114 is used to lock or unlock the annular guide portion 21.

[0062] In the embodiment of the present application, the claw mechanism 114 may include a third driving motor 1142 and a claw 1141. The claw 1141 may be disposed on the output shaft of the third driving motor 1142, and the claw 1141 may be configured to lock or unlock the annular guide portion 21 under the drive of the third driving motor 1142. In this case, through the active locking control of the claw mechanism 114 and the third driving motor 1142, the position of the end of the telescopic shaft body 113 on the annular guide portion 21 can be dynamically fixed, thereby solving the problem that it is difficult for the traditional guide structure to be locked at any position, enhancing the stability and safety during the adjustment process, and at the same time facilitating the azimuth adjustment operations such as flipping of the display terminal 2 by the azimuth adjuster 1.

[0063] In some embodiments, please refer to Figure 2 and Figure 4, the annular guide portion 21 is an annular groove, and the claw 1141 is placed in the annular groove. The number of the claws 1141 can be two, and the two claws 1141 can be movably arranged on the third drive motor 1142, and the two claws 1141 are arranged symmetrically. Specifically, the two claws 1141 can be arranged on the output shaft of the third drive motor 1142 in a symmetrical manner. When the third drive motor 1142 is running (that is, when the output shaft of the third drive motor 1142 rotates), the two claws 1141 can be driven by the third drive motor 1142 to move in directions away from each other (that is, Figure 4 In this case, the design of two centrally symmetrical claws 1141 can increase the locking contact area while balancing the force direction, reduce the risk of guide groove deformation or locking failure caused by one-sided claws 1141, and thus improve the reliability of the locking action.

[0064] In some embodiments, the annular guide portion 21 may also be an annular protrusion, and the claws 1141 are clamped on the annular protrusion. The number of the claws 1141 may be two, and the two claws 1141 can be driven by the third drive motor 1142 to move toward each other to clamp the outer wall of the annular guide portion 21, thereby locking it through the static friction force formed by the abutment.

[0065] In some embodiments, the claw 1141 may be provided with a rack, and the third drive motor 1142 is connected to a gear, and the gear is meshed with the rack, thereby driving the claw 1141 to move, so as to achieve locking and unlocking of the claw 1141 and the annular guide portion 21. In addition, the claw 1141 may be provided with two, and the racks of the two claws 1141 are connected to the gear, thereby improving the stability of the structure and transmission.

[0066] In some embodiments, the two claws 1141 can be configured to match the bending shape of the third drive motor 1142 and the annular guide 21. In this case, the claw mechanism 114 can be arranged in a limited space to lock the display terminal 2, which can reduce material costs and improve space utilization.

[0067] In some embodiments, a plurality of limit blocks are provided at intervals on the annular guide portion 21. When the display terminal 2 needs to be rotated, the third drive motor 1142 drives the claw 1141 to move until it abuts against the limit block in the rotation direction, thereby applying a rotational force to the limit block to drive the display terminal 2 to rotate; when the position of the claw 1141 on the display terminal 2 needs to be adjusted, the third drive motor 1142 drives the claw 1141 to move until it disengages from the limit block, and at this time the claw 1141 can slide freely on the annular guide portion 21.

[0068] In some embodiments, please continue to refer to Figure 3 , the jaw mechanism 114 can be hinged to the telescopic shaft body 113. Specifically, the adjusting assembly 11 can further include a connecting pin 1132, and the jaw mechanism 114 can be hinged to one end of the telescopic shaft body 113 close to the display terminal 2 through the connecting pin 1132. In this case, through the movable connection of the connecting pin 1132, the jaw mechanism 114 can adaptively adjust its cooperation state with the annular guiding portion 21 when the angle of the display terminal 2 deflects, reducing the mechanical interference between the jaw mechanism 114 and the annular guiding portion 21 caused by the position deviation during the adjustment process.

[0069] In some embodiments, the azimuth adjuster 1 can further include an electronic control unit (not shown), and the electronic control unit is electrically connected to the adjusting assembly 11 and the supporting assembly 12. The electronic control unit can be used to control the adjusting assembly 11 and the supporting assembly 12 to achieve the azimuth adjustment of the display terminal 2. In this case, through the integrated control of each driving motor by the electronic control unit, the axial, rotational, and locking actions can be coordinated intelligently, which can solve the tediousness of manual adjustment. Thus, one-key multi-degree-of-freedom automatic adjustment of the display terminal 2 can be realized to adapt to the personalized needs of users.

[0070] In some embodiments, the electronic control unit can be a control element independently provided in the azimuth adjuster 1, or it can be an electronic control unit (ECU) of the vehicle.

[0071] As follows, the process of the display terminal 2 performing azimuth adjustment through the azimuth adjuster 1 of the embodiments of the present application is described. Figure 5 is a schematic diagram of the azimuth adjuster 1 of the embodiments of the present application for realizing the horizontal swing of the display terminal 2.

[0072] Please refer to Figure 1 and Figure 5 , in the embodiments of the present application, the first driving motor 111 drives the first worm gear 112 to rotate through the first worm 1111, and a precision trapezoidal thread 1131 is used for the cooperation between the first worm gear 112 and the telescopic shaft body 113; the rotation of the first worm gear 112 drives the telescopic shaft body 113 to perform axial telescopic movement, and the telescopic displacement is linearly related to the rotation angle of the first worm gear 112, thereby pushing the display terminal 2 to realize horizontal swing. During this process, the worm gear transmission has a self-locking characteristic, which can ensure that the display terminal 2 remains stable at any position. At the same time, the trapezoidal thread 1131 pair has high transmission accuracy and load-bearing capacity.

[0073] Figure 6 is a schematic diagram of the azimuth adjuster 1 of the embodiments of the present application for realizing the omnidirectional angle adjustment of the display terminal 2.

[0074] Please refer toFigure 1 and Figure 6 In an embodiment of the present application, the second worm gear 123 is fixedly connected to the support shaft body 124, the support shaft body 124 is rigidly connected to the instrument panel 3, and the second driving motor 121 drives the second worm gear 123 through the second worm 1211. Since the second worm gear 123 is fixed, the second driving motor 121 drives the connection housing 13 and the second worm 1211 to rotate around the support shaft body 124, so that the telescopic shaft body 113 and the claw mechanism 114 can rotate accordingly. The claw mechanism 114 slides on the annular guiding portion 21 of the display terminal 2, and cooperates with the axial telescopic movement driven by the first driving motor 111 to realize the omnidirectional angle adjustment of the display terminal 2. During this adjustment process, the coordinated control of the two groups of motors can realize the arbitrary orientation positioning of the display terminal 2 in space, meeting the usage requirements of multiple scenarios.

[0075] Figure 7 FIG. is a schematic diagram of the orientation adjuster 1 in an embodiment of the present application for the display terminal 2 to realize landscape and portrait screen switching.

[0076] Please refer to Figure 1 and Figure 7 In an embodiment of the present application, the claw mechanism 114 is equipped with a bidirectional clamping device. The second driving motor 121 drives the connection housing 13 to rotate, and the third driving motor 1142 controls the movement of the claw 1141 so that the claw 1141 is tightly fitted with the side wall of the annular guiding portion 21 of the display terminal 2 for locking. After the claw mechanism 114 completes the clamping and fixing (i.e., locking), the telescopic shaft body 113 rotates synchronously with the display terminal 2, and the landscape and portrait screen switching is completed through precise rotation angle (such as 90°) control. During this adjustment process, by adjusting the rotation angle of the second driving motor 121, the arbitrary angle rotation positioning of the display terminal 2 can be realized, meeting the requirements of special usage scenarios.

[0077] The second aspect of the present application provides a display terminal 2. The display terminal 2 at least includes a display interface and a back surface opposite to the display interface. The back surface is provided with a universal connector 22 and an annular guiding portion 21, and the display terminal 2 is adjusted in orientation by the orientation adjuster 1 according to any one of the embodiments in the first aspect of the present application. By integrating the universal connector 22 and the annular guiding portion 21 on the back surface of the display terminal 2 and combining the adjustment mechanism according to any one of the above embodiments of the present application, the display terminal 2 is provided with the ability of multi-dimensional adjustment in space and does not require additional installation of a complex bracket structure.

[0078] In some embodiments, the universal connector 22 may be located at the center of the annular guiding portion 21, so that the rotation center of the adjustment assembly 11 and the rotation center of the annular guiding portion 21 are kept consistent, avoiding mechanical interference between the adjustment assembly 11 and the annular guiding portion 21 during the movement process.

[0079] The third aspect of the present application provides a vehicle, which at least includes an instrument panel 3 and a display terminal 2 according to any one of the embodiments of the second aspect of the present application. The instrument panel 3 is fixedly connected to the fixed end of the support assembly 12.
