[0033] When car owners drive out for activities, they may temporarily occupy other people's parking spaces or block cars parked in them or roads. Usually, car owners will place parking signs with mobile phone numbers on the windshield of their vehicles to facilitate others to contact them immediately. In related technologies, parking signs occupy the countertop space of the center console, but only have the function of displaying contact information, and their functions are relatively simple.

[0034] The present invention provides 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 embodiment of the present invention, Figure 1 and Figure 2 As shown, the information display device 20 includes: a shell 22, the shell 22 is provided with an installation cavity 223 and an exposed display area 21, the display area 21 is used to display contact information; a display information connector 224, the display information connector 224 is installed in the installation cavity 223 and exposed on the outer wall of the shell 22, the display information connector 224 is used to be electrically connected to the OBD interface of the car; a main control board 25, the main control board 25 is installed in the installation cavity 223 and is electrically connected to the display information connector 224; a head-up display unit, the head-up display unit is installed in the shell 22 and is electrically connected to the main control board 25, the head-up display unit includes a display screen 27, the display screen 27 is used to display the operating parameters of the car, and the display screen 27 stands relative to the horizontal plane for the car driver to look straight at.

[0036] In this embodiment, the shell 22 is used to form the overall appearance structure of the information display device 20. The display area 21 can be provided on the surface of the shell 22, or in the groove structure of the shell 22. There is no limitation here, as long as the display area 21 can be exposed. The display area 21 is used to display contact information, which can be a telephone number or a mobile phone number, or a QR code of a communication software, such as the owner's WeChat QR code. When the information display device 20 is used, it is placed on the center console of the car, and the display area 21 faces the front windshield. In this way, pedestrians outside the car can see the contact information displayed by the information display device 20 through the front windshield, so as to contact the owner in time.

[0037] The main control board 25 is used to distribute electric energy and transmit electric signals, and the head-up display unit is used to convert data signals into images and then display them on the display screen 27. The OBD (On-Board Diagnostics) interface is an interface of the on-board automatic diagnostic system of the car. 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 speed, navigation instructions, warning signals and other operating data of the car, and convert the relevant data into images and then display them on the display screen 27, so that the driver can see the operating parameters of the car from the display screen 27. The display screen 27 is erected relative to the horizontal plane, and can be angled with the horizontal plane or perpendicular to the horizontal plane. There is no limitation here, as long as the driver can see the display content of the display screen 27 in a head-up posture. Since the information display device 20 is placed on the center console for use, the position of the display screen 27 will be higher than the position of the dashboard of the car, so that the driver can see the operating parameters of the car without lowering his head when looking at the display screen 27, so as to improve driving safety. In this way, the auxiliary function of the information display device 20 is increased and the use effect is improved.

[0038] The head-up display unit may be a liquid crystal display unit or a projection display unit, which is not limited here.

[0039] For example, Figure 2 As shown, the head-up display unit further includes a projector 26, the projector 26 is electrically connected to the main control board 25, and the light emitting end of the projector 26 faces the display screen 27 to project an image on the display screen 27. The display screen 27 is a projection screen, and the projector 26 can convert the data signal from the OBD interface of the car into image light and then project it, and project the image light on the display screen 27 to form a display screen. In this way, the display mode of the head-up display unit can be simplified, and the projector 26 and the display screen 27 can be installed separately, so that the overall structure of the information display device 20 is simpler and lighter.

[0040] The display area 21 may be located at the front side or the rear side of the display screen 27 , or at the left side or the right side of the display screen 27 .

[0041] Specifically, 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 that is away from the display surface 271. 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. In this way, the position distribution of the display screen 27 and the display area 21 can be made more reasonable, so as to reduce the space occupied by the information display device 20 along the length direction of the automobile center console, and the display area 21 can remain facing the front windshield and will not be blocked by the display screen 27. The user does not need to turn the orientation of the information display device 20 before getting off the car after parking, thereby improving the convenience of using the information display device 20.

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

[0043] The projector 26 projects the image light onto the back of the display screen 27, and the user sees the projected image from the front of the display screen 27, i.e., the display surface 271. In this way, the projector 26 can also be located at the back of the display screen 27, so that the display screen 27 can be set at the frontmost part of the information display device 20, so that the display screen 27 can be as close to the driver as possible, so that the driver can clearly see the vehicle operating parameters on the display screen 27. It can be understood that in order to make the image projected by the projector 26 on the display screen 27 of a moderate size, a preset distance needs to be separated between the projector 26 and the display screen 27, and the separated distance can just be used to set the display area 21, so that the utilization rate of the housing 22 can be fully improved, and the size of the information display device 20 along the front-to-back direction can be reasonably controlled, so that the overall structure of the information display device 20 is simpler and more compact.

[0044] The projector 26 may be installed on the top of the housing 22 or in the installation cavity 223 of the housing 22 , which is not limited here.

[0045] For example, Figure 1 and Figure 2As shown, a display groove 221 is formed in the top wall of the housing 22. The display area 21 is disposed in the display groove 221 and faces the notch of the display groove 221. A light outlet 225 is formed in the groove wall of the display groove 221. The light outlet 225 penetrates through the installation cavity 223. The projector 26 is installed in the installation cavity 223. The light output end of the projector 26 projects an image onto the display screen 27 through the light outlet 225. The light outlet 225 is formed in the groove wall of the display groove 221 opposite to the display screen 27. By installing the projector 26 in the installation cavity 223 and projecting image light through the light outlet 225, the projector 26 can be hidden and protected, thereby improving the protection effect of the projector 26 and the appearance integrity of the information display device 20.

[0046] Specifically, as Figure 1 and Figure 2 shown, the cross section of the display area 21 and the notch of the display groove 221 are arranged at an angle so that the display area 21 can face the front windshield of the vehicle. The front windshield of a vehicle is usually at an angle with the tabletop of the center console. By arranging the plane where the display area 21 is located at an angle with the notch of the display groove 221, it is also to make the plane where the display area 21 is located at an angle with the tabletop of the center console, so that the front windshield of the vehicle and the plane where the display area 21 is located can tend to be parallel. In this way, pedestrians outside the vehicle can more clearly see the contact information on the display area 21 through the front windshield of the vehicle, so as to improve the information display effect of the information display device 20.

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

[0048] Exemplarily, as Figure 2 and Figure 3 shown, the display screen 27 is rotatably connected to the housing 22. The display screen 27 has a deployed position erected relative to the top wall of the housing 22 and a storage position close to the top wall of the housing 22. When the display screen 27 is in the storage position, the display screen 27 covers the notch of the display groove 221.

[0049] The display screen 27 can be switched between an unfolded position and a stored position, and the user can switch the position of the display screen 27 according to driving needs. For example, when the user is driving, the display screen 27 can be rotated to the unfolded position so that the display screen 27 can stand up to display a projection image. Before getting out of the car after parking, the user can rotate the display screen 27 to the stored position so that the display screen 27 can be laid down and close to the housing 22. It should be noted that when the display screen 27 is in the stored position, it just covers the notch of the display slot 221, and the display area 21 is within the display slot 221. However, the display screen 27, which serves as a rear projection screen, is transparent, so it will not block the line of sight of pedestrians outside the car looking at the display area 21. Thus, it can ensure that the information display device 20 can effectively display contact information after the user gets out of the car, and the display screen 27 covering the display slot 221 can also prevent foreign objects from drilling into the light outlet 225 from the display slot 221, so as to improve the protection effect on the internal structure of the information display device 20.

[0050] Specifically, as Figure 4 and Figure 5 shown, the information display device 20 further includes a retractable covering member 23. The covering member 23 is installed on the top wall of the housing 22. The covering member 23 has a switchable extended state and retracted state. When the covering member 23 is in the extended state and the display screen 27 is in the stored position, the covering member 23 covers above the display screen 27. When the covering member 23 is in the retracted state, the covering member 23 is located on one side of the display slot 221.

[0051] The covering member 23 can cover or open the display area 21 through telescopic deformation. For example, if the user does not want to display contact information after parking, the covering member 23 can be driven to cover the display area 21 to protect personal privacy. If the user needs to display contact information after parking, the covering member 23 can be driven to open the display area 21. When the covering member 23 is in the extended state and the display screen 27 is in the stored position, the covering member 23 covers above the display screen 27, so that the covering member 23 can cover the display screen 27 together to improve the hiding and protection effect on the display screen 27.

[0052] In practical applications, as Figure 4 and Figure 5 shown, when the covering member 23 is in the retracted state and the display screen 27 is in the unfolded position, the covering member 23 and the display screen 27 are respectively located on opposite sides of the display slot 221. In this way, the position distribution of the retracted covering member 23 and the unfolded display screen 27 can be made more reasonable, avoiding interference between the covering member 23 and the display screen 27, so as to improve the use convenience of the information display device 20.

[0053] The covering member 23 includes a flexible covering main body 231 that can be stretched and contracted. The flexible covering main body 231 has an extended state in which the notch of the display slot 221 is covered, and a contracted state in which the notch of the display slot 221 is opened.

[0054] The flexible covering main body 231 can be switched between an extended state and a contracted state. When the flexible covering main body 231 is in the extended state, the area of the flexible covering main body 231 is larger than the area of the notch of the display slot 221, so that the notch of the display slot 221 can be covered. When the flexible covering main body 231 is in the contracted state, the entire flexible covering main body 231 is located on one side of the notch of the display slot 221, so that the notch of the display slot 221 can be opened.

[0055] The flexible covering main body 231 can be made of cloth, leather or other materials, which is not limited here. For example, the material of the flexible covering main body 231 can be the same as the tabletop decorative layer of the instrument panel main body 10. Thus, when the flexible covering main body 231 covers the display area 21, it can be integrated with the tabletop of the instrument panel main body 10 as much as possible to improve the appearance integrity of the tabletop of the instrument panel main body 10.

[0056] When the flexible covering main body 231 is in the contracted state, it is folded in a wavy shape. In this way, the shape of the flexible covering main body 231 in the contracted state can be made more regular to improve the appearance effect.

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

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

[0059] The sliding portion 233 extends along the side of the flexible covering body 231, and a guide column 234 is protruding from the end of the sliding portion 233 in the length direction. A guide groove 222 is opened on the top wall of the shell 22, and the guide groove 222 is located on one side of the display groove 221 and extends along the sliding direction of the sliding portion 233. The guide column 234 and the guide groove 222 can be slidably matched.

[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 column 234 can be protruded only at one end of the sliding part 233 in the length direction, or can be protruded at both ends of the sliding part 233 in the length direction. There is no limitation here. The guide column 234 is slidably matched with the guide groove 222, which can guide the sliding process of the sliding part 233, so that the sliding part 233 slides along a preset track as a whole, thereby deforming the flexible covering body 231 in a preset direction, so as to improve the deformation stability of the flexible covering body 231.

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

[0062] The output shaft of the driving device 24 is connected with a screw rod, which extends along the length direction of the guide slot 222. The guide column 234 is connected with a slider, and the screw rod and the slider are threadedly matched, so that when the driving device 24 drives the screw rod to rotate, the rotation of the screw rod can be converted into the linear motion of the slider, so as to drive the guide column 234 and the sliding part 233 to make linear motion. For example, when the driving device 24 drives the screw rod to rotate forward, the slider can drive the sliding part 233 to slide in a direction away from the fixed part 232; when the driving device 24 drives the screw rod to reverse, the slider can drive the sliding part 233 to slide in a direction close to the fixed part 232. In this way, when it is necessary to drive the cover 23 to cover or open the notch of the display slot 221, it is only necessary to control the driving device 24 to operate, and there is no need for the user to manually move the cover 23, thereby improving the convenience of use of the information display device 20.

[0063] A main control board 25 may be installed in the installation cavity 223 , and a control key may be provided on the top wall of the shell 22 . The control key and the driving device 24 are both electrically connected to the main control board 25 , so that the user can control the operation of the driving device 24 by operating the control key.

[0064] In combination with the above-mentioned embodiment in which the display screen 27 is rotatable, the information display device 20 also includes a driving motor, and the output shaft of the driving 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, the driving motor can be controlled to operate 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, the present invention also proposes a car dashboard assembly, which includes a dashboard body 10 and an information display device 20. The specific structure of the information display device 20 refers to the above embodiment. Since the dashboard assembly of the present car adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the table top of the dashboard body 10 is provided with a mounting groove 11, and the information display device 20 is installed in the mounting groove 11, and the display area 21 of the information display device 20 is exposed through the notch of the mounting groove 11.

[0066] The instrument panel body 10, also known as the IP (Instrument Panel) panel, is a special component in the car that combines safety, functionality, comfort, and decoration. The instrument panel body 10 is adjacent to the front windshield in the car, so the information display device 20 embedded in the mounting groove 11 is also adjacent to the front windshield, so that pedestrians outside the car can see the contact information displayed by the information display device 20 through the front windshield, and thus contact the owner in time. Embedding the information display device 20 in the mounting groove 11 of the instrument panel body 10 can prevent the information display device 20 from occupying the table space of the instrument panel body 10, reduce the obstruction of the driver's line of sight, and improve driving safety. In addition, the information display device 20 and the instrument panel body 10 can be more firmly combined, thereby preventing the information display device 20 from flying out and hitting the human body in an emergency, thereby improving the safety of the instrument panel assembly of the car.

[0067] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
