[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] In the prior art, such as Figure 1As shown, the existing display screen 100' and the air outlet 300 of the air conditioner are installed on the dashboard 200 of the vehicle. Although the lower end of the existing display screen 100' is separated from the air outlet 300, it will block the air outlet 300. In winter, part of the hot air coming out of the air outlet 300 will be blocked by the existing display screen 100' and will be blown away from the back of the existing display screen 100' along the Figure 1 The airflow path 301 shown reaches the inner surface of the front windshield 400 of the vehicle. Since the outside environment temperature is low in winter, the hot air blown out from the air outlet 300 cools down after contacting the front windshield 400, and condenses and adheres to the inner surface of the front windshield 400, so that fog 401 is generated on the inner surface of the front windshield 400. The fog 401 on the inner surface of the windshield 400 cannot be wiped off by the wipers, which greatly affects the driver's vision.

[0044] The following first describes in detail the vehicle-mounted display screen 100 according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0045] like Figures 1 to 11 As shown, the vehicle-mounted display screen 100 according to the embodiment of the utility model includes: a display screen main body 10 and a windshield plate 20.

[0046] Specifically, the windshield 20 is connected to the back of the display screen body 10 , and the windshield 20 can separate the back side of the display screen body 10 into a first area A and a second area B to block at least part of the airflow from the first area A to the second area B.

[0047] In other words, the vehicle-mounted display screen 100 according to the embodiment of the utility model is mainly composed of a display screen body 10 and a windshield 20. The display screen body 10 may be flat, and the display screen body 10 may have two sides, which may be defined as the front and back of the display screen body 10. The front of the display screen body 10 may be provided with a display area for displaying images, and the back of the display screen body 10 may be used to connect the windshield 20.

[0048] The connection between the windshield plate 20 and the display screen body 10 may include but is not limited to direct connection, indirect connection, fixed connection and movable connection. The windshield plate 20 is arranged on the back of the display screen body 10 to improve the aesthetics.

[0049] In addition, the windshield 20 can separate the back side of the display screen body 10 into at least two zones, and the at least two zones include a first zone A and a second zone B, wherein the first zone A faces the air outlet 300, and the second zone B is separated from the air outlet 300 by the windshield 20. Therefore, the wind blown out of the air outlet 300 is partially or completely blocked by the windshield 20, and part of the airflow or all of the airflow will not enter the second zone B from the first zone A, which can prevent the hot air blown out of the air outlet 300 from reaching the inner surface of the windshield 400 and generating fog.

[0050] Therefore, according to the vehicle-mounted display screen 100 of the embodiment of the utility model, by setting a windshield 20 on the back of the display screen body 10 to separate the back of the display screen body 10 into a first area A and a second area B, the windshield 20 is used to block at least part of the airflow from the first area A to the second area B, which can effectively prevent the hot air blown out of the vehicle air outlet 300 from reaching the front windshield 400 to form fog, thereby preventing the driver's vision from being affected by the fog, which is beneficial to improving driving safety. In addition, the windshield 20 has a simple structure, and the windshield 20 is located on the back of the display screen body 10, so that the windshield 20 can be blocked by the display screen body 10 and will not appear in the driver's sight, which is beneficial to improving the aesthetics of the vehicle-mounted display screen 100.

[0051] According to one embodiment of the utility model, the wind shield 20 is rotatable between a first position and a second position and is arranged on the display screen body 10. When the wind shield 20 is in the first position, an angle is formed between the wind shield 20 and the display screen body 10 to separate the back side of the display screen body 10 into a first area A and a second area B. When the wind shield 20 is in the second position, the wind shield 20 is in contact with the display screen body 10.

[0052] Specifically, the windshield plate 20 is rotatably connected to the display screen body 10 , and the windshield plate 20 can be switched between a first position and a second position during the rotation process.

[0053] The wind shield 20 has two side surfaces in the thickness direction thereof. For the sake of convenience, the two side surfaces of the wind shield 20 may be defined as a first side surface and a second side surface.

[0054] When the windshield 20 is in the first position, there is an angle between the windshield 20 and the display screen body 10, the first side surface of the windshield 20 cooperates with a portion of the back surface of the display screen body 10 to define a first area A, and the second side surface of the windshield 20 cooperates with another portion of the back surface of the display screen body 10 to define a second area B. At this time, the windshield 20 can prevent the airflow from the first area A to enter the second area B, and the air blown out of the air outlet flows back after reaching the first side surface of the windshield 20.

[0055] When the windshield 20 is in the second position, the windshield 20 can be attached to the back of the display screen body 10. The back of the display screen body 10 and the instrument panel 200 can be spaced apart to facilitate the movement of the display screen body 10 and prevent the windshield 20 from interfering with other structures on the vehicle during the movement of the display screen body 10.

[0056] In some specific embodiments, when the wind shield 20 is in the first position, the wind shield 20 abuts against the instrument panel 200, and the first side surface of the wind shield 20, a portion of the back of the display screen body 10, and a portion of the instrument panel 200 can define a first area A, and the first side surface of the wind shield 20, another portion of the back of the display screen body 10, and another portion of the instrument panel 200 can define a second area B.

[0057] In this embodiment, the wind shield 20 can be switched between two positions, so that it is opened when the vehicle-mounted display screen 100 blocks the air outlet 300 to block the hot air blown out of the air outlet 300, and is closed when the vehicle-mounted display screen 100 does not block the air outlet 300 to facilitate the movement of the display screen body 10 and avoid interference between the vehicle-mounted display screen 100 and other structures on the vehicle during the movement.

[0058] According to some other embodiments of the present invention, the display screen body 10 is switchable between a first state and a second state. When the display screen body 10 is in the first state, the wind shield 20 is in the first position. When the display screen body 10 is in the second state, the wind shield 20 is in the second position.

[0059] Specifically, the display screen main body 10 has two states, namely a first state and a second state.

[0060] In the first state, the display screen body 10 blocks the air outlet 300, and the wind blown out of the air outlet 300 will enter the back side of the display screen body 10 under the guidance of the display screen body 10. At this time, the wind shield 20 can move to the first position to block the hot air blown out of the air outlet 300, preventing the wind from the air outlet 300 from entering the second area B from the first area A, thereby preventing the front windshield 400 from fogging.

[0061] In the second state, the display screen body 10 does not block the air outlet 300, and the wind blown out of the air outlet 300 is directed toward the driver instead of being guided to the back side of the display screen body 10. At this time, the wind shield 20 can move to the second position, that is, the wind shield 20 is in contact with the display screen body 10 to facilitate the state switching of the display screen body 10.

[0062] It should be noted that the activities performed by the display screen body 10 when switching states may include but are not limited to translation, rotation and flipping.

[0063] In some specific embodiments of the present invention, the vehicle-mounted display screen 100 further includes a bracket 30, which is mounted on the back of the display screen body 10, and the display screen body 10 can rotate relative to the bracket 30. When the display screen body 10 is in a first state after being rotated, the display screen body 10 is vertically placed, and when the display screen body 10 is in a second state after being rotated, the display screen body 10 is horizontally placed.

[0064] Specifically, the display screen body 10 may be a rectangular parallelepiped structure, and the display screen body 10 may be flat. A bracket 30 may be provided on the back of the display screen body 10, and the bracket 30 may be connected to the instrument panel 200. The display screen body 10 may rotate relative to the bracket 30. Optionally, the axis of rotation of the display screen body 10 may extend along the thickness direction of the display screen body 10. The state switching of the display screen body 10 may be achieved by rotating the display screen body 10.

[0065] Since the driver's eyes are higher than the display screen, the display screen main body 10 may be disposed tilted relative to the vertical direction, and the front side of the display screen main body 10 may be tilted upward.

[0066] When the display screen body 10 is rotated to the first state, the display screen body 10 can be placed vertically, that is, the long side of the display screen body 10 extends in the vertical direction, and the short side of the display screen body 10 extends in the horizontal direction. Figure 5 and Figure 6 As shown, the bottom of the display screen body 10 in the vertical direction will be close to and block the air outlet 300 .

[0067] When the display screen body 10 is rotated to the second state, the display screen body 10 can be placed horizontally, that is, the long side of the display screen body 10 extends in the horizontal direction, and the short side of the display screen body 10 extends in the vertical direction. Fig. 9 and Fig.10 As shown, the bottom of the display screen body 10 in the vertical direction will be away from the air outlet 300, and the air outlet 300 will not be blocked.

[0068] In other words, when the display screen body 10 is rotated to be vertical, the wind shield 20 can be opened to switch to the first position, closing the passage between the back of the display screen body 10 and the dashboard 200, and preventing the wind blown out of the air outlet 300 from reaching the front windshield 400 from the back of the display screen body 10.

[0069] When the display screen body 10 is rotated to be horizontal, the wind shield 20 can be closed to switch to the second position. Since the display screen body 10 does not block the air outlet 300, the wind blown out of the air outlet 300 will not pass through the back of the display screen body 10. The closing of the wind shield 20 can facilitate the rotation of the display screen body 10.

[0070] According to some optional embodiments of the present invention, in the length direction of the display screen body 10 , a windshield plate 20 is provided between the bracket 30 and at least one end of the display screen body 10 .

[0071] Specifically, the display screen body 10 may have two ends in its length direction, namely a first end and a second end. The arrangement of the windshield plate 20 may include but is not limited to the following situations.

[0072] In case 1, a windshield 20 is provided between the first end of the display screen body 10 and the bracket 30;

[0073] In case 2, a windshield 20 is provided between the second end of the display screen body 10 and the bracket 30;

[0074] In case three, a windshield plate 20 is provided between the first end of the display screen body 10 and the bracket 30 and between the second end of the display screen body 10 and the bracket 30 respectively;

[0075] In the above-mentioned cases, the wind blowing out of the air outlet 300 can be blocked by opening the wind shield 20 when the display screen body 10 is placed vertically.

[0076] In some optional embodiments, the display screen body 10 can be rotated 90° between vertical and horizontal positions. In this case, the above-mentioned situation 1 or situation 2 can be selected to reduce the number of windshields 20 and save the manufacturing cost of the vehicle-mounted display screen 100.

[0077] In some other embodiments, the display screen body 10 can rotate 360°. In this case, situation three can be selected. No matter which end of the display screen body 10 faces the air outlet 300, the wind shield 20 between the end and the bracket 30 can be opened to achieve the purpose of wind shielding.

[0078] According to some other embodiments of the utility model, a connecting portion 11 is provided on the back of the display screen body 10, and a rotating shaft 21 is provided at one end of the wind shield 20 close to the bracket 30, the rotating shaft 21 is connected to the connecting portion 11, and the axis of the rotating shaft 21 extends along the width direction of the display screen body 10, and the wind shield 20 can rotate around the axis of the rotating shaft 21.

[0079] Specifically, the connection portion 11 may be a structure protruding from the display screen body 10 , may be a structure embedded in the display screen body 10 , or may be a partial area on the back side of the display screen body 10 , which is not limited here.

[0080] A groove 24 is provided at one end of the windshield 20 close to the bracket 30, the rotating shaft 21 is connected to two side walls of the groove 24, and the connecting portion 11 is embedded in the groove 24. The edge of the end of the windshield 20 close to the bracket 30 can be a straight edge, so that the straight edge of the windshield 20 can be attached to the back of the display screen body 10 during the rotation process.

[0081] In addition, the shaft 21 can be rotatably connected to the connecting portion 11, the axis of the shaft 21 can extend along the width direction of the display screen body 10, and the windshield 20 can rotate around the shaft 21 so that the windshield 20 can move between the first position and the second position.

[0082] Optionally, the number of the connecting parts 11 may be two, and the two connecting parts 11 may be spaced apart along the width direction of the display screen body 10 , and the number of the rotating shafts 21 is equal to the number of the connecting parts 11 .

[0083] In this embodiment, the windshield 20 is connected to the connecting portion 11 by a rotating shaft 21, which has a simple structure and strong feasibility. The rotating shaft 21 extends along the width direction of the display screen body 10, so that the windshield 20 can extend along the width direction of the vehicle-mounted display screen 100, so that the windshield 20 can intercept the wind blown out of the air outlet 300 in the horizontal direction when it is in the first position, and prevent the hot wind from reaching the front windshield 400.

[0084] In some specific embodiments, the connection portion 11 and the rotating shaft 21 may cooperate to form a hinge, and the windshield 20 connected to the rotating shaft 21 may be opened and closed by the hinge.

[0085] In some specific embodiments of the present invention, an end of the windshield 20 away from the bracket 30 is provided with an arc-shaped edge 23 or a straight edge adapted to the surface of the instrument panel 200 .

[0086] Specifically, the shape of the edge of the windshield 20 at one end away from the bracket 30 can be adapted to the surface of the dashboard 200 so that the edge of the windshield 20 can fit seamlessly with the dashboard 200, effectively preventing the wind blown out of the air outlet 300 from passing through the back of the display screen body 10, thereby preventing the front windshield 400 from fogging.

[0087] For example, when the surface of the instrument panel 200 is curved, the end of the windshield 20 away from the bracket 30 may have a curved edge 23. Figure 7 As shown, the surface of the instrument panel 200 may be a concave arc surface, and the windshield 20 away from the arc edge 23 on the bracket 30 may protrude toward the instrument panel 200. When the display screen body 10 is placed vertically, the surface contour of the instrument panel 200 intersects with the arc edge 23 of the windshield 20 to form a cutting line, so that the first side surface of the windshield 20, the lower half of the instrument panel 200 and the lower half of the display screen body cooperate to form a triangular first area A, and the windshield 20 and the instrument panel 200 are seamlessly attached to each other, so as to prevent the wind blown out of the air outlet from passing between the windshield 20 and the instrument panel 200.

[0088] In some other embodiments, when the surface of the instrument panel 200 is a plane, the end of the windshield 20 away from the bracket 30 may have a straight edge, and the straight edge may fit seamlessly with the plane on the instrument panel 200 .

[0089] According to some optional embodiments of the utility model, the display screen body 10 is tilted relative to the vertical direction, and an electromagnet 12 is provided on one of the display screen body 10 and the windshield 20, and a magnetic member 22 is provided on the other of the display screen body 10 and the windshield 20. When the display screen body 10 is in the first state, the electromagnet 12 is disconnected, and the windshield 20 forms an angle with the display screen body 10 under the action of gravity. When the display screen body 10 is in the second state, the electromagnet 12 is energized to attract the magnetic member 22, and the windshield 20 is attached to the display screen body 10.

[0090] Specifically, the display screen body 10 can be tilted on the vehicle so that the front of the display screen body 10 can be tilted upward toward the driver's eyes, making it easier for the driver to watch.

[0091] The display screen body 10 and the windshield 20 can realize the position switching of the windshield 20 through the cooperation of the electromagnet 12 and the magnetic member 22, which may specifically include but not be limited to the following situations.

[0092] In case 1, an electromagnet 12 is provided on the back of the display screen body 10 , and a magnetic member 22 is provided on the windshield plate 20 .

[0093] In the second case, a magnetic member 22 is disposed on the back of the display screen body 10 , and an electromagnet 12 is disposed on the windshield plate 20 .

[0094] When the display screen body 10 is in the first state, the electromagnet 12 can be disconnected, and there is no adsorption effect between the electromagnet 12 and the magnetic member 22. Since the display screen body 10 is tilted relative to the vertical direction, the wind shield 20 can rotate under the action of gravity so that the end of the wind shield 20 away from the bracket 30 is separated from the display screen body 10, and the first area A and the second area B are separated.

[0095] When the display screen body 10 is in the second state, the electromagnet 12 can be energized to attract the magnetic member 22 , so that the windshield 20 fits the display screen body 10 .

[0096] In addition, during the switching of the display screen body 10 between the first state and the second state, the electromagnet 12 can also be energized to attract the magnetic part 22 so that the wind shield 20 fits the display screen body 10, thereby avoiding interference between the wind shield 20 and other structures on the dashboard 200 during the rotation of the display screen body 10.

[0097] The vehicle may be provided with a rotation control key, through which a rotation signal may be sent to the vehicle's controller, and the vehicle's controller may drive the display screen body 10 to rotate according to the rotation signal to achieve switching between horizontal and vertical placement. At the same time, according to the rotation signal, the vehicle's control may also control the electromagnet 12 to energize and attract the magnetic part 22 to ensure that the windshield 20 is in the second position during each rotation of the display screen body 10, thereby avoiding interference between the windshield 20 and the instrument panel 200.

[0098] Optionally, the electromagnet 12 may include but is not limited to a coil, and the magnetic member 22 may include but is not limited to a ferromagnet.

[0099] In some other embodiments, electromagnets 12 are respectively provided on the back of the display screen body 10 and on the windshield 20. When the display screen body 10 is placed vertically, at least one of the two electromagnets 12 is disconnected. When the display screen body 10 is placed horizontally, both electromagnets 12 are energized. The position of the windshield 20 can also be switched according to the state of the display screen body 10.

[0100] The working process of the vehicle-mounted display screen 100 of this embodiment is described in detail below.

[0101] When the display screen body 10 is placed horizontally, pressing the rotation control key sends a rotation signal to the vehicle controller. The controller first controls the electromagnet 12 to energize and attract the magnetic part 22, so that the windshield 20 fits with the back of the display screen body 10, and then controls the display screen body 10 to rotate 90°, so that the display screen body 10 becomes vertical. At this time, the display screen body 10 blocks the air outlet 300, and the controller controls the electromagnet 12 to disconnect. The windshield 20 rotates under the action of gravity and forms an angle with the display screen body 10, blocking the hot air blown out of the air outlet 300, preventing the hot air from passing through the back of the display screen body 10 to reach the inner surface of the front windshield 400, thereby preventing the inner surface of the windshield 400 from fogging.

[0102] When the display screen body 10 is placed vertically, pressing the rotation control key sends a rotation signal to the vehicle controller. The controller first controls the electromagnet 12 to energize and attract the magnetic member 22, so that the windshield 20 is attached to the back of the display screen body 10, and then controls the display screen body 10 to rotate 90°, so that the display screen body 10 becomes horizontal. When the display screen body 10 is in the horizontal state, the electromagnet 12 continues to energize and attract the magnetic member 22, and the windshield 20 is always attached to the display screen body 10.

[0103] According to some other embodiments of the present invention, the orthographic projection of the windshield 20 on the front of the display screen body 10 coincides with the display screen body 10 .

[0104] Specifically, the front of the display screen body 10 is a display surface, and the display surface is a plane, and the front of the display screen body 10 can be defined as a projection surface. The windshield 20 can overlap with the display screen body 10 when projected on the projection surface. Since the display screen body 10 is tilted, the driver's line of sight is perpendicular to the front of the display screen body 10. Therefore, the windshield 20 can be completely hidden at the back of the display screen body 10, so that the windshield 20 does not appear in the driver's field of vision, and does not affect the function and aesthetics of the vehicle-mounted display screen 100 during operation.

[0105] An embodiment of the utility model further provides a vehicle, which includes an on-board display screen 100 and a dashboard 200 according to any one of the above embodiments.

[0106] The vehicle-mounted display screen 100 is disposed on the instrument panel 200 , and an air outlet 300 is disposed on the instrument panel 200 . The air outlet 300 is used to guide airflow.

[0107] According to some optional embodiments, in the vertical direction, the highest point of the air outlet 300 may be lower than the highest point of the vehicle display screen 100 to prevent the airflow from the air outlet 300 from being higher than the vehicle display screen 100 and thus unable to be blocked by the wind shield 20. In addition, the wind shield 20 abuts against the instrument panel 200.

[0108] Since the vehicle-mounted display screen 100 according to the embodiment of the utility model has the above-mentioned technical effects, the vehicle according to the embodiment of the utility model also has the corresponding technical effects, that is, the windshield 20 is used to block at least part of the airflow from the first area A to the second area B, which can effectively prevent the hot air blown out of the vehicle air outlet 300 from reaching the front windshield 400 to form fog, thereby avoiding the driver's vision being affected by the fog, which is conducive to improving driving safety. In addition, the windshield 20 has a simple structure, and the windshield 20 is located on the back of the display screen body 10, so that the windshield 20 can be blocked by the display screen body 10 and will not appear in the driver's sight, which is conducive to improving the aesthetics of the vehicle-mounted display screen 100.

[0109] In actual use, the controller is not limited to a certain brand and model. The utility model does not need to explain this. It should be noted that the computer program loaded by the controller is not within the protection scope of the utility model. The utility model does not protect computer programs. When using the utility model, all computer programs need to be loaded additionally by technicians in this field. According to the utility model, some steps can be performed sequentially or simultaneously.
