[0033] Nowadays, when car owners drive out, they may temporarily occupy other people's parking spaces, block parked cars, or obstruct the road. Usually, car owners place a parking sign with their phone number on the windshield so that others can contact them quickly. However, in related technologies, the parking sign occupies space on the center console, but only has the function of displaying contact information, making its functionality relatively limited.

[0034] This utility model proposes an information display device 20, aiming to solve the technical problem of how to improve the use effect of the information display device 20.

[0035] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the information display device 20 includes: a housing 22, which has a mounting cavity 223 and an exposed display area 21 for displaying contact information; a display information connector 224, which is installed in the mounting cavity 223 and exposed on the outer wall of the housing 22, and is used to electrically connect to the vehicle's OBD interface; a main control board 25, which is installed in the mounting cavity 223 and electrically connected to the display information connector 224; and a head-up display unit, which is installed in the housing 22 and electrically connected to the main control board 25, the head-up display unit including a display screen 27, which is used to display the vehicle's operating parameters, and the display screen 27 is upright relative to the horizontal plane for the driver to view at eye level.

[0036] In this embodiment, the housing 22 forms the overall appearance structure of the information display device 20. The display area 21 can be located on the surface of the housing 22 or within a recessed structure of the housing 22; there is no limitation, as long as the display area 21 is exposed. The display area 21 displays contact information, which can be a phone number or mobile phone number, or a QR code for a communication software, such as the car owner's WeChat QR code. When in use, the information display device 20 is placed on the center console of the car, with the display area 21 facing the windshield. In this way, pedestrians outside the car can see the contact information displayed by the information display device 20 through the windshield, thus enabling them to contact the car owner promptly.

[0037] The main control board 25 is used to distribute power and transmit electrical signals, while the head-up display unit converts data signals into images for display on the screen 27. The OBD (On-Board Diagnostics) interface is the vehicle's on-board diagnostic system interface. By electrically connecting the OBD interface to the display information connector 224 of the information display device 20, the head-up display unit can read the vehicle's speed, navigation instructions, warning signals, and other operating data, converting the data into images for display on the screen 27, allowing the driver to see the vehicle's operating parameters. The screen 27 is upright relative to the horizontal plane; specifically, it can be at an angle to the horizontal plane or perpendicular to it, without limitation, as long as the driver can see the content displayed on the screen 27 at eye level. Since the information display device 20 is placed on the center console, the position of the screen 27 is higher than the vehicle's instrument panel, allowing the driver to see the vehicle's operating parameters without looking down, thus improving driving safety. This increases the auxiliary functions of the information display device 20 and improves its usability.

[0038] The head-up display unit can be either a liquid crystal display unit or a projection display unit; there is no limitation on this.

[0039] For example, such as Figure 2 As shown, the head-up display unit also includes a projector 26, which is electrically connected to the main control board 25. The light-emitting end of the projector 26 faces the display screen 27 to project images onto the display screen 27. The display screen 27 is a projection screen. The projector 26 can convert data signals from the car's OBD interface into image light and project it onto the display screen 27 to form a display image. In this way, the display method of the head-up display unit can be simplified, and the projector 26 and the display screen 27 can be installed separately, making the overall structure of the information display device 20 simpler and lighter.

[0040] The display area 21 can be located in front of or behind the display screen 27, or on the left or right side of the display screen 27.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the display screen 27 has a display surface 271, and the display area 21 is located on the side of the display screen 27 opposite to its display surface 271. If the side of the display screen 27 facing the driver is defined as the front side, and the side facing away from the driver is defined as the rear side, then the display surface 271 is the front surface of the display screen 27, and the display area 21 is located on the rear side of the display screen 27. This allows for a more rational distribution of the positions of the display screen 27 and the display area 21, reducing the space occupied by the information display device 20 along the length of the car's center console. Furthermore, the display area 21 remains facing the windshield and is not obstructed by the display screen 27. Users do not need to adjust the position of the information display device 20 before getting out of the car after parking, thus improving the ease of use of the information display device 20.

[0042] In practical applications, such as Figure 2 As shown, the display screen 27 is a rear projection screen, the display screen 27 stands upright relative to the top wall of the housing 22, the projector 26 is located on the side of the display screen 27 away from its display surface 271, so as to project images toward the back of the display screen 27, and the display area 21 is located between the projector 26 and the display screen 27.

[0043] Projector 26 projects image light onto the back of display screen 27, and the user sees the projected image from the front of display screen 27, i.e., display surface 271. This allows projector 26 to also be located behind display screen 27, enabling display screen 27 to be positioned at the very front of information display device 20, placing it as close as possible to the driver for easy viewing of vehicle operating parameters. It is understood that to ensure the image projected onto display screen 27 is of appropriate size, a preset distance is required between projector 26 and display screen 27. This distance is precisely used to set up display area 21, thereby maximizing the utilization of housing 22 and rationally controlling the dimensions of information display device 20 along the front-to-back direction, resulting in a simpler and more compact overall structure.

[0044] The projector 26 can be installed on the top of the housing 22 or inside the mounting cavity 223 of the housing 22, and there is no limitation on this.

[0045] For example, such as Figure 1 and Figure 2As shown, the top wall of the housing 22 has a display groove 221. The display area 21 is located within the display groove 221 and faces the opening of the groove. The groove wall of the display groove 221 has a light outlet 225, which extends through the mounting cavity 223. The projector 26 is mounted in the mounting cavity 223, and the light-emitting end of the projector 26 projects an image onto the display screen 27 through the light outlet 225. The light outlet 225 is located on the groove wall of the display groove 221 opposite to the display screen 27. By mounting the projector 26 in the mounting cavity 223 and projecting image light through the light outlet 225, the projector 26 can be hidden and protected, thereby improving both the protection of the projector 26 and the overall appearance of the information display device 20.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the cross-sections of the display area 21 and the opening of the display slot 221 are set at an angle so that the display area 21 faces the windshield of the car. The windshield of a car is usually at an angle to the surface of the center console. Setting the plane of the display area 21 at an angle to the opening of the display slot 221 is also to make the plane of the display area 21 at an angle to the surface of the center console. This allows the windshield and the plane of the display area 21 to become more parallel, so that pedestrians outside the car can see the contact information on the display area 21 more clearly through the windshield, thus improving the information display effect of the information display device 20.

[0047] The position of the display screen 27 can be fixed or switchable.

[0048] For example, such as Figure 2 and Figure 3 As shown, the display screen 27 is rotatably connected to the housing 22. The display screen 27 has an unfolded position that stands upright relative to the top wall of the housing 22, and a retracted position that is close to the top wall of the housing 22. When the display screen 27 is in the retracted position, the display screen 27 covers the opening of the display slot 221.

[0049] The display screen 27 can be switched between an unfolded position and a retracted position, allowing the user to adjust its position according to driving needs. For example, while driving, the user can rotate the display screen 27 to the unfolded position so that it can stand upright and display the projected image. After parking and before getting out of the car, the user can rotate the display screen 27 to the retracted position so that it can be folded down and close to the housing 22. It should be noted that when the display screen 27 is in the retracted position, it covers the opening of the display slot 221. The display area 21 is located within the display slot 221, but the display screen 27, as a rear projection screen, is transparent, thus not obstructing the view of pedestrians outside the vehicle towards the display area 21. This ensures that the information display device 20 can effectively display contact information after the user gets out of the car. Furthermore, the display screen 27 covering the display slot 221 also prevents foreign objects from entering the light outlet 225 through the display slot 221, thereby improving the protection of the internal structure of the information display device 20.

[0050] Specifically, such as Figure 4 and Figure 5 As shown, the information display device 20 also includes an extendable and retractable cover 23, which is installed on the top wall of the housing 22. The cover 23 has a switchable extended state and a retracted state. When the cover 23 is in the extended state and the display screen 27 is in the retracted position, the cover 23 covers the top of the display screen 27. When the cover 23 is in the retracted state, the cover 23 is located on one side of the display slot 221.

[0051] The cover 23 can extend or retract to cover or open the display area 21. For example, if a user does not want to display contact information after parking, the cover 23 can be driven to cover the display area 21 to protect their privacy. If the user needs to display contact information after parking, the cover 23 can be driven to open the display area 21. When the cover 23 is in the extended state and the display screen 27 is in the retracted position, the cover 23 covers the top of the display screen 27, thereby covering the display screen 27 and improving the hiding and protection effect of the display screen 27.

[0052] In practical applications, such as Figure 4 and Figure 5 As shown, when the cover 23 is in the retracted state and the display screen 27 is in the unfolded position, the cover 23 and the display screen 27 are located on opposite sides of the display slot 221. This allows for a more rational distribution of the positions of the cover 23 in the retracted state and the display screen 27 in the unfolded state, avoiding interference between them and improving the ease of use of the information display device 20.

[0053] The covering member 23 includes a flexible covering body 231 that can be extended and retracted. The flexible covering body 231 has an extended state that covers the opening of the display slot 221, and a retracted state that opens the opening of the display slot 221.

[0054] The flexible covering body 231 can switch between an extended state and a retracted state. When the flexible covering body 231 is in the extended state, its area is larger than the opening area of ​​the display slot 221, thus covering the opening of the display slot 221. When the flexible covering body 231 is in the retracted state, it is located entirely on one side of the opening of the display slot 221, thus opening the opening of the display slot 221.

[0055] The flexible covering body 231 can be made of fabric, leather, or other materials, without limitation. For example, the material of the flexible covering body 231 can be the same as the surface decoration layer of the dashboard body 10, so that when the flexible covering body 231 covers the display area 21, it can be integrated with the surface of the dashboard body 10 as much as possible, thereby improving the overall appearance of the dashboard body 10.

[0056] When the flexible cover body 231 is in a retracted state, it folds in a wave-like shape, which makes the shape of the flexible cover body 231 more regular when it is in a retracted state, thereby improving the appearance.

[0057] The covering member 23 further includes a fixing part 232 and a sliding part 233. The fixing part 232 and the sliding part 233 are respectively connected to the two sides of the flexible covering body 231 in the telescopic direction. The fixing part 232 is fixedly connected to the housing 22, and the sliding part 233 is slidably engaged with the housing 22 so that the sliding part 233 can move closer to or away from the fixing part 232.

[0058] The fixing part 232 can fix one side of the flexible covering body 231 to the housing 22, while the sliding part 233 can slide the other side of the flexible covering body 231 to drive the flexible covering body 231 to extend or retract. When the sliding part 233 slides away from the fixing part 232, the flexible covering body 231 is in an extended state; when the sliding part 233 slides close to the fixing part 232, the flexible covering body 231 is in a retracted state. When it is necessary to drive the flexible covering body 231 to deform, the sliding part 233 can be driven to slide, so that the driving force can first act on the sliding part 233 and not directly act on the flexible covering body 231, thereby avoiding the flexible covering body 231 from being easily pulled and damaged, thus improving the stability of the deformation process of the covering part 23 and increasing the service life of the covering part 23.

[0059] The sliding part 233 extends along the side of the flexible covering body 231. A guide post 234 protrudes from the end of the sliding part 233 in the length direction. A guide groove 222 is provided on the top wall of the housing 22. The guide groove 222 is located on one side of the display groove 221 and extends along the sliding direction of the sliding part 233. The guide post 234 and the guide groove 222 are slidably engaged.

[0060] The length of the sliding part 233 is greater than or equal to the length of the movable side of the flexible covering body 231. The sliding part 233 can slide along the top wall of the housing 22. The guide post 234 can protrude from only one end of the sliding part 233 along its length, or it can protrude from both ends of the sliding part 233 along its length; there is no limitation on this. The guide post 234 slides in conjunction with the guide groove 222, which can guide the sliding process of the sliding part 233, so that the entire sliding part 233 slides along a preset trajectory, thereby causing the flexible covering body 231 to deform in a preset direction, thereby improving the deformation stability of the flexible covering body 231.

[0061] The guide groove 222 passes through the mounting cavity 223. The information display device 20 also includes a drive device 24 installed in the mounting cavity 223. The output shaft of the drive device 24 is coupled to the guide post 234 to drive the guide post 234 to slide.

[0062] The output shaft of the drive device 24 is connected to a lead screw, which extends along the length of the guide groove 222. A guide post 234 is connected to a slider, and the lead screw and slider are threaded together. Therefore, when the drive device 24 drives the lead screw to rotate, it converts the rotation of the lead screw into linear motion of the slider, which in turn drives the guide post 234 and the sliding part 233 to move linearly. For example, when the drive device 24 drives the lead screw to rotate clockwise, the slider causes the sliding part 233 to slide away from the fixed part 232; when the drive device 24 drives the lead screw to rotate counterclockwise, the slider causes the sliding part 233 to slide closer to the fixed part 232. Thus, when it is necessary to drive the cover 23 to cover or open the opening of the display slot 221, only the drive device 24 needs to be controlled, eliminating the need for the user to manually move the cover 23, thereby improving the ease of use of the information display device 20.

[0063] The main control board 25 can be installed in the mounting cavity 223. The top wall of the housing 22 can be provided with control keys. The control keys and the drive device 24 are electrically connected to the main control board 25, so that the user can control the operation of the drive device 24 by operating the control keys.

[0064] In conjunction with the above embodiment where the display screen 27 can rotate, the information display device 20 also includes a drive motor. The output shaft of the drive motor is connected to the display screen 27 to drive the display screen 27 to rotate. In this way, when the user needs to switch the position of the display screen 27, he / she can control the operation of the drive motor without manually moving the display screen 27, thereby improving the ease of use of the information display device 20.

[0065] like Figure 6 and Figure 7 As shown, this utility model also proposes an instrument panel assembly for automobiles. The instrument panel assembly includes an instrument panel body 10 and an information display device 20. The specific structure of the information display device 20 is as described in the above embodiments. Since this instrument panel assembly adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. The instrument panel body 10 has a mounting groove 11 on its surface. The information display device 20 is mounted in the mounting groove 11, and the display area 21 of the information display device 20 is exposed through the opening of the mounting groove 11.

[0066] The dashboard body 10, also known as the IP (Instrument Panel), is a special component in a car that integrates safety, functionality, comfort, and aesthetics. The dashboard body 10 is located near the windshield, therefore the information display device 20, embedded in the mounting slot 11, is also near the windshield. This allows pedestrians outside the vehicle to see the contact information displayed on the information display device 20 through the windshield, enabling them to contact the vehicle owner promptly. Embedding the information display device 20 in the mounting slot 11 of the dashboard body 10 avoids it occupying surface space, reducing obstruction of the driver's view and improving driving safety. Furthermore, the information display device 20 is more securely integrated with the dashboard body 10, preventing it from flying out and impacting a person in an emergency, thus improving the safety of the car's dashboard components.

[0067] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
