Fig. 1 shows an exploded view of a vehicle-mounted display device in an embodiment of the present invention; Fig. 2 shows a schematic structural view of a rotating mechanism in an embodiment of the present invention; Example related structure.

In the embodiment of the present application, the rotating mechanism 10 is used to connect two components (herein referred to as a first component and a second component). For example, in some embodiments, the rotating mechanism 10 can connect the display screen 20 and the instrument panel (for example, the embodiment of FIG. 1 ), at this time, the first part can be the display screen 20 or the instrument panel, and the second part can be corresponding is the instrument panel or display screen 20 . Among them, the display screen 20 is used for displaying functions such as text, images, animations and videos, and can also control the interactive operation of entertainment equipment such as air conditioners, audio and lighting in the car through operations. In some other embodiments, the rotating mechanism 10 can also connect the display screen 20 and the seat. In this case, the first component can be the display screen 20 or the seat, and the second component can be the seat or the display screen 20 accordingly.

It is easy to understand that in other embodiments, the rotating mechanism 10 can also be used in any other occasions where the rotating mechanism 10 is required to connect components.

FIG. 3 shows a schematic cross-sectional view of the vehicle display device shown in FIG. 1 .

1-3, in some embodiments of the present application, the rotating mechanism 10 may include a first member 12 and a second member 14, the first member 12 is connected to the first part, and the second member 14 is connected to the second part . The first member 12 is connected to the second member 14 through a spherical pair having an axis of rotation, and the first member 12 and the second member 14 can be operatively rotated around a rotation axis with respect to each other, and the first member 12 and the second The member 14 can remain locked in any rotational position in the non-operated state. For example, in some embodiments, the first part is a display screen 20, the second part is an instrument panel, one end of the first member 12 is connected to the display screen 20, one end of the second member 14 is connected to the instrument panel, and the first member 12 The ends facing each other with the second member 14 are connected by the aforementioned spherical pair. When the user operates the display screen 20, the display screen 20 can rotate relative to the instrument panel around the aforementioned rotation axis, so as to adjust the display screen 20 to a suitable position and keep mutual locking when it is not operated, so as to ensure normal use. It can adapt to the vision of different drivers, as well as the viewing needs of the main driver and co-pilot, and improve the viewing comfort of users. Further, it is also possible to avoid generation of reflected light that interferes with the driver's field of vision, thereby reducing the risk of traffic accidents.

Wherein, the rotation axis is located on a plane that is tangent to the spherical surface of the spherical pair and takes the antidiametric point of the spherical surface as the tangent point, and the rotation axis passes through the antidiametric point of the spherical surface. It should be understood that the spherical pair is a kinematic pair in which the two components that make up the kinematic pair can perform three independent relative rotations around an axis, and the two components that make up the spherical pair are in contact with a spherical surface. For example, in any three-dimensional space coordinate system, the two components constituting the spherical pair can rotate around the three axes of X, Y, and Z, so that the first component 12 and the second component 14 have three directions. rotational degrees of freedom. In the embodiment of the present application, the rotation axes of the first member 12 and the second member 14 are located on a plane that is tangent to the spherical surface of the spherical pair and takes the antidiametric point of the spherical surface as the tangent point, and the rotation axis passes through The antiradial point of a spherical surface. That is to say, in the three-dimensional coordinate system, the first member 12 and the second member 14 only have rotational degrees of freedom in two directions, and the rotational degrees of freedom in the radial direction passing through the antiradial point of the aforementioned spherical surface are constraint. For example, in the embodiment shown in Figure 3, the left-right direction is the X direction, the direction perpendicular to the paper is the Y direction, and the up-down direction (axis direction) is the Z direction. The first member 12 and the second member 14 are in the three-dimensional coordinates In the system, the rotational degree of freedom in the Z direction is constrained.

It is particularly emphasized that since the display screen 20 has functions such as display and interactive control, it needs to be connected with the vehicle power supply and the control unit in the instrument panel through the wire harness 22, so the degree of freedom of rotation in the aforementioned one direction is restricted. Constraints can avoid the entanglement of the wire harness 22 caused by the rotation of the display screen 20 and the connection failure caused by the rotation of the two ends of the wire harness 22 . In addition, in the actual application process, since the display screen 20 may interfere with components such as the instrument panel during the rotation process, therefore, in the embodiment of the application, the aforementioned rotation axis is defined to be tangent to the spherical surface of the spherical pair. And on the plane with the antidiametric point of the spherical surface as the tangent point, and the rotation axis passes through the antidiametric point of the spherical surface, the inconvenience caused by the interference between the display screen 20 and other components can be avoided to a certain extent.

It can be understood that, in the embodiment shown in accompanying drawings 1 and 3, the first component 12 is connected to the instrument panel (not shown), and the second component 14 is connected to the display screen 20, that is, the first component is the instrument panel , the second component is the display screen 20 . In other embodiments, the first component 12 can also be connected to the display screen 20 , while the second component 14 is connected to the instrument panel, that is, the first component is the display screen 20 and the second component is the instrument panel. That is to say, in the embodiment of the present application, there is no limitation on which components are the first component and the second component, which can be set as required.

In the embodiment of the present application, a rotating mechanism 10 as described above can be set between the aforementioned first component and the second component, and in some implementations, at least two (for example, two or more) can also be set ) The rotating mechanism 10 as previously described. For example, in some embodiments, two rotating mechanisms 10 as mentioned above are arranged between the first part and the second part, so that the connection and support stability between the first part and the second part can be ensured and balance.

Below, some embodiments of the present application will be further described in detail.

As shown in the drawings, in some embodiments of the present application, the rotating mechanism 10 is connected between the display screen 20 and the instrument panel, the first member 12 is connected with the instrument panel, and the second member 14 is connected with the display screen 20 for making The display screen 20 can rotate around the rotation axis relative to the instrument panel, that is, to realize the adaptive adjustment of the display screen 20 to the vision of different users (for example, the main driver and the co-pilot, or different drivers). Wherein, the user can also operate the vehicle-mounted display device through the display screen 20 . The first member 12 has a ball joint 126 and the second member 14 has a socket joint 142 for receiving the ball joint 126, the socket joint 142 being configured to allow the first member 12 and the second member 14 are operable to rotate relative to each other about the axis of rotation and enable the first member 12 and the second member 14 to remain locked in either rotational position in an unoperated state. The rotation axis is located on a plane that is tangent to the spherical surface of the ball joint 126 and takes the antidiametric point of the spherical surface as the tangent point, and the rotation axis passes through the antidiametric point of the spherical surface of the ball joint 126 .

Ball joint 126 may be removably inserted into socket joint 142 . The socket connector 142 can be regarded as a jaw, which includes a body 1422 and at least two petals 1424 disposed on the body 1422 separated by openings, and the openings are located on both sides of the petals 1424 . The petals 1424 are configured such that at least two of the petals 1424 form a socket that mates with the ball joint 126 when brought close together or connected to each other. Furthermore, the socket connector 142 also has a through hole (not shown) passing through the main body 1422 to pass through the socket, and the through hole is used for the wire harness 22 to pass through and connect with the display screen 20 .

Further, the second member 14 also includes a fastener 144 for locking the ball joint 126 in the socket of the socket connection 142 . Specifically, the fastener 144 is in the shape of an unclosed ring, which is sheathed on the outside of the petal-shaped member 1424, so that the petal-shaped member can 1424 are close to or connected to each other, thereby constraining the ball head of the ball joint 126 in the socket of the socket joint 142 and preventing the two from moving relative to each other. Specifically, in one embodiment, the socket connector 142 has a plurality of petals 1424 whose inner and outer surfaces are approximately spherical. When not constrained by the fastener 144, openings are formed between the sides of the petals 1424. The ends of the petals 1424 facing the ball joint 126 define an opening into which the ball head of the ball joint 126 can be inserted. When the fastener 144 is sleeved on the outside of the petal member 1424, and the petal member 1424 is hugged and close to or connected to each other, the inner surface of the petal member 1424 defines a diameter and the diameter of the ball head of the ball joint 126 is approximately Equal to the spherical cavity, the ends of the petals 1424 can limit the disengagement of the ball head of the ball joint 126 from the socket.

It should be pointed out that, in the embodiment of the present application, the ball joint 126 is considered as a male connecting part, and the socket connecting part 142 is considered as a female connecting part.

In some embodiments, the ball joint 126 is an interference fit with the socket joint 142 so that the first member 12 and the second member 14 can remain locked in any rotational position when not in operation. When the ball joint 126 is inserted into the socket joint 142 , the petal 1424 can hug the ball head of the ball joint 126 so as to limit the mutual rotation of the first member 12 and the second member 14 . When the user rotates the display screen 20, the external force is transmitted to the second member 14 and overcomes the clasping force between the petal piece 1424 and the ball joint 126, so that the display screen 20 and the second member 14 can be opposite to the first member 12. Make a corresponding rotation movement with the instrument panel. In other embodiments, the ball joint 126 and the socket joint 142 may also be connected in other ways. For example, specifically, the ball head of the ball joint 126 is provided with a plurality of dimples, and correspondingly, the socket of the socket joint 142 is provided with buckles matching the dimples. When the ball joint 126 is inserted into the socket joint 142, the aforesaid at least one buckle snaps into at least one of the plurality of recesses of the ball joint 126, and the ball joint 126 is not in operation. locked in a rotational position.

It can be understood that, as a preferred embodiment, the shape of the ball head of the ball joint 126 is preferably spherical, but in some other embodiments, other shapes such as oval may also be used, which is not limited here, but can be It is enough to achieve the above-mentioned rotational degree of freedom and the purpose of maintaining locking in the state of no operation.

In some embodiments, the first member 12 includes a main body 122 , a ball joint 126 , and a neck 124 between the main body 122 and the ball joint 126 . The main body 122 can be in the shape of a plate for fixed connection with the instrument panel, and the cross section of the neck 124 can be circular, oval, rectangular or other shapes. In this way, the distance between the ball joint 126 and the main body 122 can be increased, so that the ball head of the ball joint 126 can be inserted into the socket of the socket joint 142 as much as possible, so as to ensure the reliability of the connection. In addition, the distance between the display screen 20 and the instrument panel is increased, which is beneficial to realize the rotation adjustment of the display screen 20 relative to the instrument panel. Further, the neck 124 is longitudinally connected between the main body 122 and the ball joint 126 , the neck 124 is perpendicular to the main body 122 , and the longitudinal axis of the neck 124 passes through the spherical surface of the ball joint 126 and perpendicular to the axis of rotation. Specifically in the embodiment, the cross section of the neck 124 is circular, one end of the neck 124 is vertically connected to the center of the main body 122, the other end is connected to the ball joint 126, and the central axis of the neck 124 is connected to the ball The antiradial points of the spherical surfaces of the member 126 are collinear and perpendicular to the axis of rotation. In this way, the rotation structure can be an axisymmetric structure, so that the stability and reliability of the rotation of the display screen 20 relative to the instrument panel can be further improved. In addition, the rotation structure can also make the angles of rotation of the display screen 20 in two opposite directions around the rotation axis equal, so as to ensure that both the main driver and the co-pilot can have a good view.

In the embodiment of the present application, the first component 12 further includes a wire harness channel 128 passing through the first component 12 . Specifically, in some embodiments, the wire harness channel 128 runs through the main body 122, the neck 124 and the ball joint 126, and is used to introduce the power line and signal line connected to the display screen 20 into the instrument panel, so as to communicate with the power supply and the control unit. connect. Furthermore, the central axis of the wire harness channel 128 passes through the center of the ball joint 126 and is perpendicular to the rotation axis, so that during the rotation of the display screen 20, the wire harness 22 can be avoided as far as possible from being bent, pulled and entangled. , resulting in poor contact. As a preferred embodiment, the central axis of the wire harness passage 128 coincides with the central axis of the neck 124 , so that the wire harness 22 extends in a straight line, avoids bending, and further prevents the wire harness 22 from being pulled and entangled.

In some embodiments, the radial dimension of the wire harness channel 128 is larger than the outer diameter of the wire harness 22 , and the radial dimension of the wire harness channel 128 is from the end of the first member 12 away from the second member 14 to the end of the first member 12 close to the second member 14 Gradual increase, specifically in the embodiment, that is, the radial dimension of the wire harness channel 128 gradually increases from the main body 122 to the ball joint 126 . For example, in the embodiment shown in FIG. 3 , the cross-section of the wire harness channel 128 is circular, and the inner diameter of the wire harness channel 128 gradually increases from the main body 122 to the ball joint 126, so that the distance between the wire harness 22 and the inner wall of the wire harness channel 128 maintain a safety gap. It should be pointed out that since the instrument panel is fixed, and the display screen 20 is in the process of rotating relative to the instrument panel, the wire harness 22 is easily rubbed or squeezed against the inner wall of the wire harness passage 128 by the display screen 20, so that the wire harness 22 is relatively opposite to the wire harness passage. The inner wall of 128 is still, so that the connection between the wire harness 22 and the display screen 20 causes disconnection or poor contact during the continuous rotation of the display screen 20 . The inner diameter of the wire harness channel 128 is set to gradually increase from the main body 122 to the ball joint 126 , so as to avoid contact of the wire harness 22 with the inner wall of the wire harness channel 128 near the display screen 20 as much as possible. In this way, the connection reliability of the wire harness 22 is ensured.

It should be understood that, in order to ensure connection reliability, when the ball head of the ball joint 126 is limited to the socket of the socket joint 142, no matter whether the spherical surface formed by the petals 1424 is continuous (the petals 1424 are mutually connected) or discontinuous, the spherical surface formed by the petals 1424 should cover at least 50% of the surface of the ball head of the ball joint 126 inserted into the socket joint 142, that is, the ball joint 126 and socket connector 142 are allowed to rotate over a range of at least 2π steradian. In other words, when the petals 1424 are constrained to be connected to each other by the fastener 144, the spherical surface formed by the petals 1424 should at least cover a spherical arc greater than 180 degrees, so that the ball head of the ball joint 126 and the socket can be ensured The reliability of the socket connection of the connecting piece 142 has a larger rotation angle. But when the rotating mechanism 10 is used to adjust the rotation of the display screen 20 relative to the instrument panel, if the rotation angle between the first member 12 and the second member 14 is too large, the display screen connected to the second member 14 will 20 interferes with an instrument panel or other component, therefore, socket connector 142 is configured to allow rotational movement between first member 12 and second member 14 for a predetermined range of rotational angles.

It should be noted that steradian is the measurement unit of solid angle. The angle of the spherical surface with the area of radius squared (r ² ) to the antidiametric point is equal to 1 steradian. Taking the entire spherical surface as an example, the area of the entire spherical surface is 4πr ² , so the entire sphere has 4π steradians.

As a preferred implementation manner, the rotation angle between the first member 12 and the second member 14 is 60 degrees. In this way, it can be ensured that the display screen 20 connected to the second member 14 does not interfere with the instrument panel. For example, in one embodiment, the display screen 20 has an initial position during its rotation, and a first limit position and a second limit position where it rotates in opposite directions around the rotation axis. When the display screen 20 is in the initial position (the embodiment shown in Figure 3), the line (diameter) of the antidiametric points of the spherical surface of the ball joint 126 is perpendicular to the display screen 20; when the display screen 20 is in the first position The limit position is that the display screen 20 is rotated 30 degrees in one direction relative to the initial position, and when the display screen 20 is in the second limit position, the display screen 20 is rotated 30 degrees in the opposite direction relative to the initial position.

It can be understood that when the rotation mechanism 10 is used to connect other components, the preset rotation angle can be determined according to specific conditions, which is not limited here.

In some embodiments, the socket connector 142 further includes a limiting structure, which is used to constrain the ball joint 126 so that the first member 12 and the second member 14 are within a preset rotation angle range internal rotation. Specifically, the limiting structure is a lip 1426 extending from the petal part 1424 toward the end of the ball joint 126, and the lip 1426 can cooperate with the neck 124 of the first member 12 to limit the position during the rotation process. Thus, the first member 12 and the second member 14 can rotate within a preset angle range. In some other embodiments, the limiting structure includes a dimple provided on the ball joint 126 and a buckle correspondingly provided in the socket of the socket connector 142 and matched with the dimple. When the first member 12 If the relative rotation with the second member 14 exceeds the preset angle range, the buckle can cooperate with the recess, thereby preventing the first member 12 and the second member 14 from continuing to rotate relative to each other. In some other embodiments, the limiting structure can also be a wedge-shaped surface arranged in the socket of the socket connector 142. When the relative rotation of the first member 12 and the second member 14 exceeds a preset angle range, the wedge-shaped surface Cooperating with the ball head of the ball head connector 126 , relying on the friction force between the wedge surface and the ball head, it can also prevent the first member 12 and the second member 14 from continuing to rotate relative to each other.

Referring to FIGS. 3-5 , in some embodiments, the second member 14 further includes a mounting bracket 146 , and the socket connector 142 is mounted on the mounting bracket 146 . Further, the mounting bracket 146 includes a bracket body 1462 and a housing portion 1464 disposed on one side of the bracket body 1462, the housing portion 1464 has a housing cavity for receiving and fixing the socket connector 142, and the side of the bracket body 1462 is away from the housing portion 1464 A first opening (not shown) communicating with the receiving cavity is provided so that the socket connector 142 can pass into the receiving cavity. The side of the receiving portion 1464 facing away from the bracket body 1462 is provided with a second opening communicating with the receiving cavity, and the ball joint 126 enters the receiving cavity through the second opening to cooperate with the socket connecting member 142 . Wherein, the size of the second opening is smaller than the smallest radial dimension of the socket connector 142 to prevent the socket connector 142 and the fastening member 144 from disengaging from the second opening.

During the assembly process, firstly, the socket connector 142 is placed in the receiving cavity through the first opening, and the ball joint 126 is matched with the socket of the socket connector 142 through the second opening.
