[0050] As described in the background, the existing rotary shaft type storage display screen is arranged in front of the gull-wing door mounting area, and when the display screen is unfolded, there is a problem of affecting the driving safety or easily causing harm to the front passengers and the driver when the car collides. The inventor found that the reason for this problem is that in the above-mentioned rotary shaft type storage display screen, the rotary shaft is located at one end of the display screen facing the front space; the above-mentioned rotary shaft type storage display screen usually needs to be arranged in front of the gull-wing door mounting area, that is, it is usually installed on the roof of the front space and located between the two front seats. When it is in the storage state, the entire rotary shaft type storage display screen can be approximately horizontal. When it is unfolded, the display screen rotates counterclockwise around the rotary shaft, and the end of the display screen facing the rear space is usually kept on the driver's side and is inclined, thus affecting the driving safety of the driver, etc.

[0051] In view of the above technical problems, the embodiment of the present application provides a vehicle-mounted display device and a car, which is installed on the roof of the front space of the car through a fixing frame and located between the headrests of the two front seats. The display screen is connected to the fixing frame through a connecting rod assembly. The connecting rod assembly includes a first connecting rod and a second connecting rod, and a four-link mechanism is formed between the first connecting rod, the second connecting rod, the display screen and the fixing frame. The first connecting rod is connected with a power assembly for receiving power and rotating to fold or unfold the display screen.

[0052] Further, when the vehicle-mounted display device is unfolded, the end of the display screen facing the rear space rotates counterclockwise, and at the same time, the end of the display screen facing the front space also rotates counterclockwise, so that the display screen can be prevented from entering the space in front of the headrests of the two front seats, that is, the display screen will not be kept on the driver's side, which can reduce the influence on the driving safety, and when the car collides, harm to the front passengers and the driver can be avoided.

[0053] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0054] In order to facilitate the description of the embodiments of the present application, the coordinate system in the drawings is described. In the drawings, the X-axis direction is the front-rear direction of the vehicle body, the Y-axis direction is the width direction of the vehicle body, and the Z-axis direction is the height direction of the vehicle body.

[0055] As Figures 1 to 4As shown, the automobile provided by the embodiment of the present application comprises a vehicle body 200 and a vehicle display device 100, wherein along the X-axis direction, the space in the vehicle body 200 can be divided into a front-row space 201 and a rear-row space 202, the front-row space 201 is also referred to as a one-row space, and the rear-row space 202 is also referred to as a two-row space.

[0056] The front-row space 201 is provided with two front-row seats 210, and along the Y-axis direction, the two front-row seats 210 are arranged at intervals and maintain a certain interval between the two front-row seats 210. The vehicle display device 100 is used to improve the travel entertainment of the rear-row passengers and enhance the intelligent level of the vehicle cabin. The vehicle display device 100 comprises a display screen 10 and a folding mechanism 20, wherein the folding mechanism 20 comprises a fixing frame 21 and a connecting rod assembly, and the folding mechanism 20 is installed on the inner surface of the roof of the vehicle body 200 through the fixing frame 21.

[0057] Along the Y-axis direction, the entire vehicle display device 100 is located between the headrests of the two front-row seats 210, and along the Z-axis direction, when the vehicle display device 100 is in a storage state, the entire vehicle display device 100 is located in the space above the head of the front-row passenger, and the display side of the display screen 10 faces the side of the roof.

[0058] Further, the automobile provided by the present application further comprises two gull-wing doors 220, and along the Y-axis direction, the two gull-wing doors 220 are installed at the roof of the rear-row space 202 through a connecting structure, and the two gull-wing doors 220 can be rotated along the X-axis direction relative to the vehicle body 200 to open or close. In order to avoid the interference of the two gull-wing doors 220 when opening or closing on the vehicle display device 100 or the influence of the vehicle display device 100 on the convenience of passengers entering or exiting after the gull-wing doors 220 are opened, along the X-axis direction, the vehicle display device 100 is arranged in front of the connecting structure, that is, the fixing frame 21 is arranged in front of the connecting structure and located between the headrests of the two front-row seats 210.

[0059] On the basis of the above-mentioned embodiment, the folding mechanism 20 provided by the embodiment of the present application is used to mount the display screen 10 and can make the display screen 10 be stored, unfolded or adjust the display angle of the display screen 10. As shown in Figure 5 and Figure 6 As shown, the folding mechanism 20 further comprises a connecting rod assembly arranged at least on one side of the display screen 10, and along the Y-axis direction, the connecting rod assembly is arranged on the side surface of the display screen 10 and connected with the side surface of the display screen 10.

[0060] The connecting rod assembly comprises a first connecting rod 22 and a second connecting rod 23, wherein a first end of the first connecting rod 22 is rotationally connected with the fixed frame 21, and a second end of the first connecting rod 22 is rotationally connected with a side surface of the display screen 10; a first end of the second connecting rod 23 is rotationally connected with the fixed frame 21, and a second end of the second connecting rod 23 is connected with a side surface of the display screen 10, and a four-connecting-rod mechanism is formed between the first connecting rod 22, the second connecting rod 23, the fixed frame 21 and the display screen 10.

[0061] Exemplarily, the fixed frame 21 is configured as an angle steel structure, and the extension direction of the fixed frame 21 is consistent with the X-axis direction. The fixed frame 21 comprises a first mounting surface and a second mounting surface. The first mounting surface is attached to and fixed with the inner surface of the vehicle body 200, for example, a hexagonal socket bolt is inserted and mounted on the first mounting surface, and the fixed frame 21 is mounted to the roof of the vehicle through the hexagonal socket bolt.

[0062] The second mounting surface is provided with two rotation shaft holes in the X-axis direction, respectively, for rotationally connecting with the first connecting rod 22 and the second connecting rod 23. In the X-axis direction, the first connecting rod 22 and the second connecting rod 23 are arranged in front and back, and the first end of the first connecting rod 22 is arranged closer to the front row space 201 than the first end of the second connecting rod 23. The first connecting rod 22 and the second connecting rod 23 can be connected to the rotation shaft holes of the fixed frame 21 through rotation shafts, and are prevented from being detached through a locking nut sleeved on the rotation shaft.

[0063] The second end of the first connecting rod 22 and the second end of the second connecting rod 23 are rotationally connected with the display screen 10, respectively. The display screen 10 of the embodiment of the present application comprises a screen body 11 and a surrounding frame 12, and the surrounding frame 12 is arranged around the screen body 11, which not only protects the screen body 11, but also is rotationally connected with the connecting rods of the folding mechanism 20. The surrounding frame 12 is provided with a first rotation shaft 123 connected with the first connecting rod 22 and a second rotation shaft 124 connected with the second connecting rod 23.

[0064] Exemplarily, the display screen 10 can be a rectangular screen, and correspondingly, the surrounding frame 12 is configured as a rectangular surrounding frame matched with the display screen. It is continued to refer to Figure 5 and Figure 6 The surrounding frame 12 comprises two first frame edges 121 and two second frame edges 122, wherein along the rotation direction of the display screen 10, the two first frame edges 121 are oppositely arranged, and the two second frame edges 122 are used for connecting two ends of the two first frame edges 121 and surrounding the rectangular surrounding frame.

[0065] In other words, as shown in Figure 5 when the display screen 10 is in the folded storage state, along the X-axis direction, the two first frame edges 121 are oppositely arranged, along the Y-axis direction, the two second frame edges 122 are oppositely arranged, and each end of each second frame edge 122 is connected with the two first frame edges 121, respectively, and the rectangular surrounding frame is surrounded.

[0066] Further, the first rotation shaft 123 and the second rotation shaft 124 are arranged on the second frame edge 122 respectively, and when the vehicle-mounted display device 100 is in the folded storage state, i.e., the display screen 10 is in the storage state, the first rotation shaft 123 is closer to the front-row space 201 than the second rotation shaft 124, or in other words, along the X-axis direction, the first rotation shaft 123 is located in front of the second rotation shaft 124.

[0067] In the embodiment of the present application, the folding mechanism 20 is configured to rotate the display screen 10 counterclockwise when the display screen 10 is unfolded, i.e., the first end of the display screen 10 rotates counterclockwise, and the second end of the display screen 10 also rotates counterclockwise, and the display screen 10 is kept at a certain angle of inclination.

[0068] Conversely, when the display screen 10 is folded and stored, the display screen 10 rotates clockwise toward the end of the rear-row space 202, i.e., the first end of the display screen 10 rotates clockwise, and the second end of the display screen 10 rotates clockwise toward the front-row space 201, and returns to the horizontal state.

[0069] In the prior art, the rotation shaft of the rotation shaft type storage display screen is located at the end of the display screen facing the front-row space, and when the display screen is kept in the storage state, the display side of the display screen faces the roof of the vehicle, and when the display screen is unfolded, the end of the display screen facing the rear-row space rotates counterclockwise, and the display screen is usually kept on the side of the driver and is arranged at an inclination, thus affecting the driving safety of the driver, etc.

[0070] However, the vehicle-mounted display device 100 provided in the embodiment of the present application is located between the headrests of the two front-row seats 210, and when the vehicle-mounted display device 100 is unfolded, the first end of the display screen 10 rotates counterclockwise, and at the same time, the second end of the display screen 10 also rotates counterclockwise, which is different from the unfolding method of the rotation shaft type storage display screen, and can avoid the display screen 10 entering the space in front of the headrests of the two front-row seats 210, and after the display screen 10 is completely unfolded, the display screen 10 can be flush with the headrests of the front-row seats 210 or located behind the headrests, which can avoid the space on the side of the driver, i.e., the display screen 10 will not be kept on the side of the driver, and can reduce the influence on the driving safety, and when the vehicle is in a collision, can avoid causing harm to the front-row passengers and the driver.

[0071] On the basis of the above-mentioned embodiment, in order to ensure the stability of the display screen 10 during the folding and storage or unfolding process, the folding structure includes two link assemblies, and the two link assemblies are arranged on the two sides of the display screen 10 along the Y-axis direction.

[0072] Accordingly, the fixing frame 21 in the folding mechanism 20 provided in this application embodiment is a split structure, or in other words, the folding mechanism 20 includes two fixing frames 21, which are the first fixing frame and the second fixing frame, respectively. Along the Y-axis direction, the first fixing frame and the second fixing frame are fixed to the roof of the vehicle relative to each other and spaced apart, and are located between the headrests of the two front seats 210.

[0073] The two linkage assemblies described above can be symmetrically arranged on both sides of the display screen 10 and can rotate synchronously. One linkage assembly is used to connect the first fixing frame and one side of the display screen 10, and the other linkage assembly is used to connect the second fixing frame and the other side of the display screen 10. With this arrangement, under the action of the two linkage assemblies, the display screen 10 can rotate smoothly and maintain a certain tilt angle, which is within the rotation angle range of the linkage assemblies.

[0074] This application uses the folding mechanism 20, which includes two sets of linkage components, as an example for illustration. It should be noted that in some embodiments, rotational force can be directly applied to the display screen 10 to make the entire folding mechanism 20 fold or unfold. This application does not limit this.

[0075] Preferably, such as Figure 7 As shown, the folding mechanism 20 provided in this embodiment of the application also includes a power component 24, which is used to provide rotational force to the first link 22 in each link assembly so that the entire folding mechanism 20 can be folded or unfolded.

[0076] Specifically, the power assembly 24 includes a drive motor 241 and a transmission shaft 242. The drive motor 241 can be fixed on the first fixed frame, and the drive motor 241 is connected to the transmission shaft 242 in a transmission connection. The drive shaft of the drive motor 241 is arranged parallel to the transmission shaft 242. The transmission shaft 242 extends along the Y-axis direction, and both ends of the transmission shaft 242 are respectively connected to the first connecting rod 22 of each connecting rod assembly. Under the action of the drive motor 241, the first connecting rod 22 can rotate relative to the fixed frame 21. It should be noted that the above-mentioned power assembly 24 is not limited to the drive motor 241 and transmission shaft 242, and can also be a worm gear. This application embodiment does not limit this.

[0077] The power assembly 24 also includes a drive gear 243 and a driven gear 244 that cooperates with the drive gear 243. The drive gear 243 is mounted on the drive shaft of the drive motor 241, and the driven gear 244 is located in the middle of the transmission shaft 242. The two ends of the transmission shaft 242 are respectively provided with transmission splines 245, and the first connecting rod 22 is provided with a keyway 224 that cooperates with the transmission splines 245.

[0078] In this way, when the display screen 10 needs to be folded or unfolded, the rotation direction of the driving motor 241 is controlled, and the driving force of the driving motor 241 is transmitted to the first connecting rod 22 through the driving gear 243, the driven gear 244 and the transmission shaft 242, and the first connecting rod 22 drives the second connecting rod 23 and the display screen 10 to adjust the display screen 10 to be folded or unfolded.

[0079] Further, as shown in Figure 8 The first connecting rod 22 provided by the embodiment of the present application comprises a first connecting section 221, a second connecting section 222 and a third connecting section 223 arranged in sequence; one end of the first connecting section 221 is provided with a key groove 224, which is matched with the transmission spline 245 of the transmission shaft 242, that is, the first connecting section 221 is used for receiving the power from the power assembly 24. The other end of the first connecting section 221 is connected with the second connecting section 222, and a first obtuse angle is formed between the first connecting section 221 and the second connecting section 222, that is, a bending angle is arranged between the first connecting section 221 and the second connecting section 222.

[0080] The other end of the second connecting section 222 is connected with the third connecting section 223, and a second obtuse angle is formed between the second connecting section 222 and the third connecting section 223, that is, a bending angle is arranged between the second connecting section 222 and the third connecting section 223. One end of the third connecting section 223 away from the second connecting section 222 is provided with a rotating shaft hole 225 connected with the display screen 10, that is, the third connecting section 223 is used for being connected with the first rotating shaft 123 of the frame 12 to realize the rotating connection between the first connecting rod 22 and the display screen 10.

[0081] In this way, the first connecting rod 22 provided by the embodiment of the present application has two bending angles, which can make the whole vehicle-mounted display device 100 be folded and stored in a horizontal state, and occupy a smaller space in the Z-axis direction, which is beneficial to reduce the overall height of the vehicle body 200; and when the vehicle-mounted display device 100 is completely unfolded, the occupied space of the vehicle-mounted display device 100 in the vehicle body 200 is reduced.

[0082] As shown in Figure 9 The second connecting rod 23 in the embodiment of the present application comprises a fourth connecting section 231 and a fifth connecting section 232 connected with each other; one end of the fourth connecting section 231 is rotatably connected with the fixed frame 21 through a rotating shaft, and the other end of the fourth connecting section 231 is provided with a rotating shaft hole 225, which is matched with the rotating shaft hole 225 of the fixed frame 21, and a rotating shaft is inserted into the two rotating shaft holes 225 to realize the rotating connection between the fourth connecting section 231 and the fixed frame 21.

[0083] The other end of the fourth connecting section 231 is connected with the fifth connecting section 232, and the two form a third obtuse angle, that is, there is a bending angle between the fourth connecting section 231 and the fifth connecting section 232.
