Detailed Description

Embodiments of the present invention will be described in detail below, by way of example with reference to the accompanying drawings.

An adjusting device for an in-vehicle screen according to an embodiment of the present invention is described below with reference to fig. 1 to 6, and an in-vehicle screen assembly 100100 and a vehicle having the adjusting device for an in-vehicle screen are also provided.

As shown in fig. 1 to 5, the adjusting device of the in-vehicle screen includes: screen bracket 2 and multi-link mechanism. Wherein the screen support 2 is adapted to mount a vehicle mounted screen 9.

The multi-link mechanism is movably connected with the screen bracket 2, is of a symmetrical structure and is used for driving the screen bracket 2 to deflect and translate towards the main driving side or deflect and translate towards the copilot side so as to realize the adjustment of the vehicle-mounted screen 9. In the embodiment of the invention, with the Y-axis direction and the X-axis direction in the vehicle coordinate system as references, when the on-vehicle screen 9 is adjusted to the main driving side, the multi-link mechanism drives the screen bracket 2 to translate in the Y-axis direction while deflecting in the X-axis direction toward the main driving side, and when the on-vehicle screen 9 is adjusted to the co-driving side, the multi-link mechanism drives the screen bracket 2 to translate in the Y-axis direction while deflecting in the X-axis direction toward the co-driving side.

According to the adjusting device of the vehicle-mounted screen, the screen bracket 2 is driven to deflect by the multi-link mechanism with a symmetrical structure, so that the offset of the vehicle-mounted screen 9 to the rotating side can be effectively reduced, interference with peripheral parts is reduced, and the movement path of the center of the vehicle-mounted screen can be shorter and more compact. Compared with other existing link mechanisms, the mechanism has higher adjustment flexibility, and limit boundary adjustment is performed according to instruments, steering wheels, combination switches and the like of the cockpit.

Further, the multi-link mechanism includes: the first link mechanism and the second link mechanism are symmetrically arranged relative to the screen bracket 2 and are connected, and the movement strokes of the first link mechanism and the second link mechanism are different, so that the adjustment of the vehicle-mounted screen 9 is realized. As shown in fig. 2, the first link mechanism and the second link mechanism are designed to be symmetrical structures, and the first link mechanism and the second link mechanism can drive the screen bracket 2 to deflect and translate towards the main driving side or deflect and translate towards the co-driving side through different strokes of the movement of the first link mechanism and the second link mechanism.

In some embodiments, the first linkage comprises: a first link 3 and a third link 5, the second link mechanism comprising: a second link 4 and a fourth link 6.

One end of the first connecting rod 3 is movably connected to one side of the screen bracket 2, and the other end is movably connected to the third connecting rod 5; and one end of the second connecting rod 4 is movably connected to the other side of the screen bracket 2; and the other end is movably connected with a fourth connecting rod 6, wherein the fourth connecting rod 6 is movably connected with the third connecting rod 5, and a directional sliding piece 7 is arranged at the joint of the third connecting rod 5 and the fourth connecting rod 6.

That is, one side of the screen bracket 2 is movably connected to one end of the first link 3, and the other end of the first link 3 is movably connected to one end of the third link 5; correspondingly, the other side of the screen bracket 2 is movably connected with one end of the second connecting rod 4, the other end of the second connecting rod 4 is movably connected with one end of the fourth connecting rod 6, and the other end of the third connecting rod 5 is movably connected with the other end of the fourth connecting rod 6, so that a multi-connecting rod mechanism of the screen bracket 2, the first connecting rod 3, the third connecting rod 5, the fourth connecting rod 6 and the second connecting rod 4 is formed, a directional sliding piece 7 is arranged at the joint of the third connecting rod 5 and the fourth connecting rod 6, the third connecting rod 5 and the fourth connecting rod 6 are movably connected between the first connecting rod 3 and the second connecting rod 4, and the directional sliding piece 7 is enabled to directionally slide, so that the movement track of the multi-connecting rod mechanism is unique.

In addition, the multi-link mechanism further includes: at least one driving component 8, the driving component 8 drives the first connecting rod 3 and the second connecting rod 4 to translate, and drives the directional sliding piece to directionally slide, so that the movement stroke of the first connecting rod 3 and the movement stroke of the second connecting rod 4 are different, and the screen bracket 2 deflects towards the main driving side or the auxiliary driving side.

Specifically, the driving component 8 drives the first connecting rod 3 and the second connecting rod 4 to translate along the Y-axis direction, so that the third connecting rod 5 and the fourth connecting rod 6 can synchronously move, and the screen bracket 2 can drive the vehicle-mounted screen 9 to perform deflection movement by adjusting the stroke difference between the first connecting rod 3 and the second connecting rod 4.

In the present embodiment, when the first link 3 and the second link 4 may be disposed at both left and right sides of the screen bracket 2, respectively, when the speed at which the driving unit 8 drives the first link 3 to move is different from the speed at which the driving unit drives the second link 4 to move, the travel of both can be made different under the same time condition, so that the screen bracket 2 can be deflected toward the primary driver side or toward the secondary driver side during the forward movement.

Of course, when the first link 3 and the second link 4 are disposed on the upper and lower sides of the screen frame 2, the screen frame 2 may be deflected upward or downward when the speed of driving the first link 3 by the driving assembly 8 is different from the speed of driving the second link 4.

In the embodiment of the invention, in order to solve the problem of left-right deflection of the vehicle-mounted screen 9, the first connecting rod 3 and the second connecting rod 4 are respectively connected to the left side and the right side of the screen bracket 2, when the driving component 8 drives the first connecting rod 3 and the second connecting rod 4 to move in a differential mode, the first connecting rod 3 and the second connecting rod 4 drive the two sides of the screen bracket 2 and the vehicle-mounted screen 9 to push in the Y-axis direction, and the forward moving strokes of the first connecting rod 3 and the second connecting rod 4 are different (in front of and behind), so that the screen bracket 2 and the vehicle-mounted screen 9 can deflect to the main driving side or the co-driving side.

The movement strokes of the first connecting rod 3 and the second connecting rod 4 are different, and the output rotation speed of the driving assembly 8 can be adjusted, so that the movement speeds of the first connecting rod 3 and the second connecting rod 4 are different, and thus, the movement strokes of the first connecting rod 3 and the second connecting rod 4 are different under the same working time, and the forward movement strokes of the first connecting rod 3 and the second connecting rod 4 are different.

For example, when the in-vehicle screen 9 needs to be deflected toward the main driver side, the first link 3 on the side close to the main driver side moves relatively short in stroke and the second link 4 on the side far from the main driver side moves relatively long in stroke, so that the screen bracket 2 and the in-vehicle screen 9 can be deflected toward the main driver side. Similarly, when the on-vehicle screen 9 is required to deflect toward the secondary driver side, the second link 4 on the secondary driver side moves relatively short in stroke and the first link 3 on the secondary driver side moves relatively long in stroke, so that the screen bracket 2 and the on-vehicle screen 9 can deflect toward the secondary driver side, as shown with reference to fig. 2.

In the embodiment of the invention, the first connecting rod 3, the third connecting rod 5, the second connecting rod 4 and the fourth connecting rod 6 are symmetrically arranged on two sides of the screen bracket 2 respectively, wherein the first connecting rod 3 and the second connecting rod 4 have the same structure, and the third connecting rod 5 and the fourth connecting rod 6 have the same structure, so that deflection of the vehicle-mounted screen 9 can be realized only by changing the moving speed of the first connecting rod 3 and the second connecting rod 4.

Compared with the conventional push-forward and fixed-axis rotating mechanism 22, the adjusting device of the vehicle-mounted screen can reduce the offset of the vehicle-mounted screen 9 to the rotating side, reduce the interference with peripheral parts, and has higher platformization and universality. And, the movement path of the center of the vehicle-mounted screen 9 is shorter and more compact, and the size of the whole adjusting device of the vehicle-mounted screen is smaller, more compact and more reliable. Compared with other existing link mechanisms, the mechanism has higher adjustment flexibility and is convenient to adjust according to the limiting boundaries of instruments, steering wheels, combination switches and the like of the cockpit.

In the embodiment of the invention, one ends of the first connecting rod 3 and the second connecting rod 4 are respectively provided with a connecting bolt 91, and the two sides of the screen bracket 2 are hinged through the connecting bolts 91 so as to ensure that the first connecting rod 3 and the second connecting rod 4 drive the screen bracket 2 to deflect.

It is to be noted that the forward movement mentioned above refers to movement toward the rear of the vehicle in the Y-axis direction.

Therefore, the driving assembly 8 drives the first connecting rod 3 and the second connecting rod 4 to move in a differential mode, so that the screen bracket 2 and the vehicle-mounted screen 9 are driven to deflect towards the main driving side or towards the auxiliary driving side. And, the movement path of the center of the vehicle-mounted screen 9 is shorter and more compact, and the size of the whole adjusting device of the vehicle-mounted screen is smaller, more compact and more reliable. Compared with other existing link mechanisms, the mechanism has higher adjustment flexibility and is convenient to adjust according to the limiting boundaries of instruments, steering wheels, combination switches and the like of the cockpit.

In some embodiments, the drive assembly 8 comprises: a first drive assembly 81 and a second drive assembly 82.

The first driving assembly 81 includes: the first driving piece 811, the first transmission piece 812 and the second transmission piece 813, the first driving piece 811 is in transmission connection with the first transmission piece 812, the second transmission piece 813 is arranged on the first transmission piece 812, and the second transmission piece 813 can move relative to the first transmission piece 812 or the first transmission piece 812 drives the second transmission piece 813 to move, and the second transmission piece 813 is movably connected with the other end of the first connecting rod 3.

Thus, the first driving member 811 is in driving connection with the first driving member 812, the second driving member 813 is disposed on the first driving member 812, the first driving member 812 is driven to rotate by the first driving member 811, and the second driving member 813 can move on the first driving member 812, or the first driving member 812 drives the second driving member 813 to move together, so as to drive the first link 3 to translate along the Y-axis direction. Specifically, in the embodiment of the present invention, when the first driving member 811 drives the first driving member 812 to rotate, the first driving member 812 is in rotation fit with the output shaft of the first driving member 811, and the second driving member 813 moves relative to the first driving member 812, at this time, the second driving member 813 drives one side of the first link 3, the screen bracket 2 and the vehicle-mounted screen 9 to translate along the Y-axis direction.

And, the second driving assembly 82 includes: the second driving member 821 is in transmission connection with the third driving member 822, the fourth driving member 823 is arranged on the third driving member 822, the fourth driving member 823 can move relative to the third driving member 822 or the fourth driving member 823 drives the third driving member 822 to move, and the fourth driving member 823 is movably connected with the other end of the second connecting rod 4. In the embodiment of the present invention, the fourth transmission member 823 moves axially on the third transmission member 822 under the driving of the second driving member 821 to drive the second link 4, the screen bracket 2 and the other side of the vehicle-mounted screen 9 to translate along the Y-axis direction, in the same principle as the first driving member 81.

Then, by adjusting the speeds of the first link 3 and the second link 4 so that the stroke difference is generated therebetween, it is possible to achieve deflection of the in-vehicle screen 9 toward the main driving or co-driving side.

Specifically, the first transmission member 812 is a first screw, the second transmission member 813 is a first screw nut, the third transmission member 822 is a second screw, and the fourth transmission member 823 is a second screw nut. Thus, the first driving member 811 may be a first motor, the output shaft of the motor is in transmission connection with the first screw, the first screw nut is in screw fit with the first screw, after the first motor is started, the first screw rotates in situ, and the first screw nut rotates on the first screw in a screw manner, so as to drive one side of the first link 3, the screen bracket 2 and the vehicle-mounted screen 9 to move forward. Similarly, the third transmission member 822 and the fourth transmission member 823 are the same, and the first transmission member 812 and the second transmission member 813 are symmetrically disposed on both sides of the screen bracket 2, so that the second driving member 821 drives the second link 4, the screen bracket 2 and the other side of the vehicle-mounted screen 9 to move forward.

And, one end of the first screw nut is connected to the connecting bolt 91 at one end of the first link 3, and similarly, one end of the second screw nut is connected to the connecting bolt 91 at one end of the second link 4.

Of course, the first drive assembly 81 may also include only; the first driving piece 811 and the first transmission piece 812 are movably connected with the other end of the first connecting rod 3, and when the first driving piece 811 drives the first transmission piece 812 to rotate, the first transmission piece 812 can move and does not rotate in situ, so that the first connecting rod 3 can be driven to move; and, the second drive assembly 82 may also include only; the second driving member 821 and the second transmission member 813, and make the second transmission member 813 movably connected with the other end of the second link 4, when the second driving member 821 drives the second transmission member 813 to rotate, the second transmission member 813 can move and drive the second link 4 to move, so that the screen bracket 2 and the vehicle-mounted screen 9 can deflect towards one side of the primary driver or one side of the secondary driver due to the difference between the moving stroke of the first link 3 and the moving stroke of the second link 4.

The extending directions of the first screw and the second screw are parallel to each other and symmetrically arranged on both sides of the screen bracket 2. In this way, only the moving speeds of the first link 3 and the second link 4 need to be changed, and deflection of the in-vehicle screen 9 can be achieved.

In the embodiment of the invention, the first connecting rod 3 can be split into an upper casting and a lower casting for processing and is connected into a whole through three hinge bolts. The first link 3 is connected to the hinge bolt by two bushings 92, which reduces wear. Wherein the front end of the first connecting rod 3 is connected with one side of the screen bracket 2 through a hinge bolt and two bushings 92; the middle part of the first connecting rod 3 is connected with the third connecting rod 5 through a hinge bolt and two bushings 92, and the third connecting rod 5 is connected with the second connecting rod 4 through a hinge bolt and two bushings 92. Similarly, the second link 4 has the same structure as the first link 3 and the same connection manner as described above.

In some embodiments, the adjusting device of the in-vehicle screen further includes: and the controller is electrically connected with the first driving assembly 81 and the second driving assembly 82 respectively so as to control the opening and closing operations of the first driving assembly 81 and the second control assembly.

Wherein the controller is specifically configured to: the rotational speeds of the first and second driving assemblies 81 and 82 are controlled to be different so that the stroke of movement of the first link 3 is different from the stroke of movement of the second link 4. That is, by controlling the rotational speeds of the first driving unit 81 and the second driving unit 82 to be different, the stroke of the movement of the first link 3 and the stroke of the movement of the second link 4 can be made different under the same time condition, so that the adjustment of the in-vehicle screen 9 can be achieved.

Specifically, when the controller receives a signal deflected toward the side of the passenger, it controls the rotation speed of the first driving member 811 to be higher than that of the second driving member 821, and after the first screw nut driven by the first driving member 811 is moved to the first screw end position after being energized for a while, it touches the signal switch, and the first driving member 811 and the second driving member 821 are deenergized; the second screw nut driven by the second driving member 821 has a smaller moving distance than the first screw nut, and the second link 4 swings inward under the constraint of the second screw nut pushing and the directional slider 7 connected to the fourth link 6 and is transferred to the screen bracket 2; the first connecting rod 3 makes forward pushing action under the constraint of the pushing of the first screw nut and the directional sliding piece 7 connected through the third connecting rod 5 and transmits the forward pushing action to the screen bracket 2; the screen bracket 2 connected with the vehicle-mounted screen 9 realizes left side turning and forward movement under the combined action of the first connecting rod 3 and the second connecting rod 4, so as to realize left side turning movement of the vehicle-mounted screen 9, as shown in fig. 2; correspondingly, when the controller receives a signal deflected towards the main driving side, the rotation speed of the second driving member 821 is higher than that of the first driving member 811, and the movement stroke of the second lead screw nut is driven to exceed that of the first lead screw nut, and the stroke difference is reflected to the vehicle-mounted screen 9 through the screen bracket 2, so that the right-side turning movement of the vehicle-mounted screen 9 is realized, as shown in the figure.

Therefore, by adjusting the moving strokes of the second and first lead screw nuts on the second and first lead screws, respectively, the side turning control of the in-vehicle screen 9 can be achieved under the constraint of the third and fourth links 5 and 6 and the directional slider 7.

The movement time of the main side steering driver and the auxiliary side steering driver can be about 2s, and the first nut and the second nut move for different strokes within the same time, so that the movement speed of the second nut and the movement speed of the first nut need to be adjusted. The first screw nut is screwed with the first screw, and the second screw nut is screwed with the second screw, so that the rotation speed of the first screw driven by the first driving member 811 and the rotation speed of the second screw driven by the second driving member 821 need to be adjusted. The first driving member 811 and the second driving member 821 may employ an adjustable speed motor, and the rotation speed of the motor is adjusted by voltage, so as to realize the side rotation of the vehicle screen 9 in the main driving direction and the auxiliary driving direction.

Of course, the driving assembly 8 may be one, and include: the third driving piece and the differential mechanism are in transmission connection.

And, the first transmission assembly includes: one end of the third driving piece is in transmission connection with the first driving piece through a differential mechanism, the second driving piece is arranged on the first driving piece, the second driving piece moves relative to the first driving piece or the first driving piece drives the second driving piece to move, and the second driving piece is movably connected with the other end of the first connecting rod 3; the second transmission assembly includes: the other end of the first driving piece is in transmission connection with the third driving piece, the fourth driving piece is arranged on the third driving piece, the fourth driving piece moves relative to the third driving piece or the third driving piece drives the fourth driving piece to move, and the fourth driving piece is movably connected with the other end of the second connecting rod 4.

In this way, the rotation speeds are output from the two ends of the third driving member, wherein the rotation speed of one end changes the output speed through the differential mechanism, so that the first connecting rod 3 moves according to the changed output rotation speed, the second connecting rod 4 moves according to the output rotation speed of the third driving member, differential movement of the first connecting rod 3 and the second connecting rod 4 can be realized, and the movement strokes of the first connecting rod 3 and the second connecting rod 4 are different, so that the screen bracket 2 deflects.

In some embodiments, the connection between the two ends of the third link 5 and/or the fourth link 6 and the middle of itself constitutes a triangle. Therefore, the connecting lines between the two ends and the middle part of the third connecting rod 5 form a triangle, so that the third connecting rod 5 is a bent special-shaped connecting rod, and the structure of the fourth connecting rod 6 is similar, thereby improving the overall stability of the multi-connecting rod mechanism and ensuring the movement stability of the multi-connecting rod mechanism.

In some embodiments, the angle of deflection of the screen support 2 towards the primary or secondary driving side is α, which satisfies the relation: alpha is more than 0 DEG and less than or equal to 15 deg. Thus, when the vehicle-mounted screen 9 is in the initial position and the vehicle-mounted screen 9 is parallel to the X-axis direction of the vehicle, and when the screen bracket 2 drives the vehicle-mounted screen 9 to deflect towards the main driving side or the co-driving side, the vehicle-mounted screen 6 deflects a certain angle relative to the X-axis direction of the vehicle, and the deflection angle is limited to be in the range of 0-15 degrees, so that good experience feeling of both the main driver and the co-driver is ensured.

In some embodiments, as shown in fig. 6, the screen bracket 2 includes: and one end of the rotating mechanism 22 is used for being connected with the vehicle-mounted screen 9, and the rotating mechanism 22 can drive the vehicle-mounted screen 9 to rotate around the center of the rotating mechanism. In this way, the rotating mechanism 22 can drive the vehicle-mounted screen 9 to rotate, so that 360-degree arbitrary angle rotation of the vehicle-mounted screen 9 is realized.

And, the rotation mechanism 22 includes: the third driving component 221 and the rotating disc 222, one end of the rotating disc 222 is in transmission connection with the third driving component 221, the other end of the rotating disc 222 is used for being connected with the vehicle-mounted screen 9, and the third driving piece b drives the rotating disc 222 to rotate so as to drive the vehicle-mounted screen 9 to rotate. Thus, one end of the rotating disc 222 is connected with the third driving component 221 in a transmission way, and the other end of the rotating disc 222 is fixedly connected with the vehicle-mounted screen 9, and when the third driving component 221 drives the rotating disc 222 to rotate, the vehicle-mounted screen 9 can be driven to rotate.
