[0044] In order to better understand the technical solution of the utility model, the embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0046] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] The utility model proposes an automobile, which includes a vehicle body, a front windshield assembly 10, an instrument panel assembly 30 and a vehicle body controller, wherein the front windshield assembly 10 is connected to the vehicle body; the instrument panel assembly 30 includes an instrument panel panel 31 and an instrument projector assembly 33, the instrument panel panel 31 is connected to the vehicle body, the instrument projector assembly 33 is rotatably connected to the instrument panel panel 31, and the instrument projector assembly 33 can move between a working state and a hidden state, and is used for projecting driving parameters of the automobile onto the front windshield assembly 10; the vehicle body controller is electrically connected to the instrument projector assembly 33, and is used for controlling the operation of the instrument projector assembly 33.

[0048] The body of the automobile proposed in the utility model can be used as a supporting frame for the entire automobile, and the front half of the body is enclosed with the doors, the front windshield assembly 10, the side windows and the sunroof to form a cockpit; the front windshield assembly 10 is installed on a frame located at the front of the automobile, and can be bonded to the body by polyurethane glass glue, so that the connection between the front windshield assembly 10 and the body is firm and sealed; the instrument panel 31 of the instrument panel assembly 30 is arranged in the cockpit formed by the body, and it can be extended along the width direction of the body, and the instrument panel 31 provides an installation position for the instrument projector 331, and the instrument projector 331 can project the driving parameters of the automobile onto the front windshield assembly 10, so that the driver can view the data in time during driving; the body controller can be used as a central control system to transmit signals to the instrument projector assembly 33, and control the conversion of the instrument projector assembly 33 between the working state and the hidden state.

[0049] Compared with the driver needing to lower his head to look for data on the indicator or display screen during driving, the instrument projector assembly 33 proposed in the utility model can project the driving parameters on the front windshield assembly 10. This arrangement allows the driver to view the driving parameters without lowering his head, thereby increasing the safety of the car during driving. At the same time, by setting a rotational connection between the instrument projector assembly 33 and the instrument panel 31, the instrument projector assembly 33 can rotate around the instrument panel 31 to switch between the working state and the hidden state, thereby improving the space utilization of the instrument panel assembly 30 and reducing the possibility of dust accumulation. Due to the arrangement of the instrument projector assembly 33, the embodiment of the utility model can eliminate multiple or large-size LCD screens on the instrument panel, avoiding the driver's visual fatigue caused by the high saturation color and light sensitivity of the LCD screen, better improving the user's driving pleasure and interactive experience, and reducing production costs.

[0050] Combination Figures 1 to 5 , the specific structure of the instrument projector assembly 33 is explained.

[0051] In some embodiments of the present invention, the instrument projector assembly 33 includes a driving member and an instrument projector 331, the driving member is transmission-connected to the instrument projector 331, and the driving member is connected to the instrument panel 31; the driving member is electrically connected to the vehicle body controller; the instrument projector 331 is rotationally connected to the instrument panel 31, and the driving member drives the instrument projector 331 to move between a working state and a hidden state. When the instrument projector 331 is in the working state, the instrument projector 331 projects the driving parameters of the car onto the front windshield assembly 10.

[0052] In this embodiment, the driving member is used to provide the instrument projector 331 with the power to move. The driving member can be a motor, or a combination of a cylinder and a gear rack mechanism. Of course, it can also be other driving members that can drive the instrument projector 331 to rotate, which is not limited here. The instrument projector 331 and the instrument panel 31 are rotatably connected through a rotating shaft 332. The driving member and the instrument panel 31 can be set to a detachable connection mode such as screw connection and clamping connection to facilitate the disassembly and assembly between the two; it can also be set to a fixed connection to maintain the connection stability between the two; of course, in other embodiments of the utility model, there may be no connection relationship between the driving member and the instrument panel 31, which is not limited here.

[0053] Specifically, taking the driving member as an electric motor, the power output end of the motor is transmission-connected to the rotating shaft 332 of the instrument projector 331, and because the motor is electrically connected to the body controller, the body controller will issue a working instruction to the motor to start working, so that the power output end of the motor rotates to drive the rotating shaft 332 to rotate around the instrument panel panel 31.

[0054] It can be known that a receiving space 311 for receiving the instrument projector assembly 33 can be provided in the instrument panel 31. When the instrument projector 331 is rotated out of the receiving space 311 and rotated to the working position (i.e., the intersection between the plane where the lens 335e of the instrument projector 331 is located and the plane where the rotating shaft 332 is located forms an obtuse angle), the lens 335e can project the driving parameters to the front windshield assembly 10, which is the working state; when the instrument projector 331 is not needed, the vehicle body controller can issue a working instruction to the driving member to rotate the instrument projector 331 from the working position back to the receiving space 311 of the instrument panel 31, which is the hidden state. By changing the position of the instrument projector 331 in different states, the overall volume of the instrument panel assembly 30 will not be too large, and the space utilization rate of the instrument panel assembly 30 can also be improved.

[0055] Furthermore, in order to reduce dust accumulation between the instrument projector 331 and the dashboard panel 31, in some embodiments of the present invention, the straight-line distance between the plane where the rotation axis 332 is located and the side of the dashboard panel 31 close to the front windshield assembly 10 is defined as d, satisfying the relationship: 0.2mm≤d≤0.8mm.

[0056] It can be known that the range value of the straight-line distance between the plane where the rotating shaft 332 is located and the side of the dashboard panel 31 close to the front windshield assembly 10 is between 0.2mm and 0.8mm. When the straight-line distance between the plane where the rotating shaft 332 is located and the side of the dashboard panel 31 close to the front windshield assembly 10 is within this range, when the instrument projector 331 is in a hidden state, the instrument projector 331 will not protrude from the dashboard assembly 30, while maintaining the appearance, the possibility of dust accumulation is also reduced. If the range value of the straight-line distance between the plane where the rotating shaft 332 is located and the side of the dashboard panel 31 close to the front windshield assembly 10 is less than 0.2mm, the instrument projector 331 may extend to the dashboard panel 31, thereby reducing the space utilization of the dashboard assembly 30; if the range value of the straight-line distance between the plane where the rotating shaft 332 is located and the side of the dashboard panel 31 close to the front windshield assembly 10 is greater than 0.8mm, the surface difference between the instrument projector 331 and the dashboard panel 31 is too large, thereby aggravating the dust accumulation.

[0057] It is understandable that, combined with Figure 1 Let's see. Figure 1 The dummy in the figure serves as the driver, and there is no obstruction when the dummy observes the projection field of view, and the projection field of view of the instrument projector 331 is not blocked during the projection process, so that the driver can see the information projected by the instrument projector 331 on the front windshield assembly 10 during driving, which enables the driver to pay more attention to the road condition information ahead and respond in time during driving, effectively avoiding the safety hazard caused by the driver's wide range of vision movement.

[0058] Furthermore, in some embodiments of the present invention, in addition to the rotating shaft 332, the instrument projector 331 also includes a shell 333, a sensing structure 334 and a projection structure 335. The rotating shaft 332 is rotationally connected to the instrument panel panel 31, and the driving member is transmission-connected to the rotating shaft 332; the shell 333 is connected to the rotating shaft 332, and the shell 333 forms a accommodating space 333a; the sensing structure 334 is arranged in the accommodating space 333a, and the sensing structure 334 is electrically connected to the vehicle body controller; the projection structure 335 is arranged in the accommodating space 333a, and is spaced apart from the sensing structure 334, and the projection structure 335 and the sensing structure 334 are electrically connected; when the rotating shaft 332 drives the shell 333 to rotate to a working state, the projection structure 335 projects the driving parameters of the car onto the front windshield assembly 10.

[0059] In this embodiment, the housing 333 can provide an installation position for other components of the instrument projector 331. The accommodation space 333a formed by the housing 333 can be used to accommodate the sensing structure 334 and the projection structure 335, and the cross-section of the housing 333 can be set in an arc shape to make the arrangement between the sensing structure 334 and the projection structure 335 more reasonable; the rotating shaft 332 and the housing 333 can be detachably connected by screw connection, snap connection, etc., and of course, can also be integrally formed or other fixed connection methods, which are not limited here. The sensing structure 334 is electrically connected to the body controller to receive the signal sent by the body controller, and the projection structure 335 is electrically connected to the sensing structure 334, and converts the signal transmitted by the sensing structure 334 into a pattern, which contains the driving parameters of the car, and then projects the pattern onto the front windshield assembly 10 through the lens 335e of the projection structure 335.

[0060] The specific structure of the sensing structure 334 is described below; specifically, the sensing structure 334 includes a wire 334a and a circuit board 334b, the wire 334a is arranged in the accommodating space 333a, and a portion of the wire 334a extends out of the housing 333, and is used to be electrically connected to the vehicle body controller; the circuit board 334b ​​is electrically connected to the wire 334a and the projection structure 335. Of course, in other embodiments of the utility model, the sensing structure 334 and the vehicle body controller can be set to be wirelessly connected, which is not limited here.

[0061] The specific structure of the projection structure 335 is described; specifically, the projection structure 335 includes a light-emitting element 335a, a prism 335b, an optical conductor 335c, a projector regulator 335d and a lens 335e, the light-emitting element 335a is electrically connected to the circuit board 334b, the prism 335b is stacked with the light-emitting element 335a, and is used to deflect the light emitted by the light-emitting element 335a; the lens 335e is arranged on a side of the housing 333 close to the front windshield assembly 10, and the optical conductor 335c is arranged between the prism 335b and the lens 335e; the optical conductor 335c is used to convert the light deflected by the prism 335b into driving parameters, and the lens 335e is used to project the driving parameters onto the front windshield assembly 10; the projector regulator 335d is electrically connected to the body controller, and is arranged on a side of the lens 335e close to the projector, and the projector regulator 335d is used to adjust the projection clarity of the lens 335e.

[0062] It can be understood that the circuit board 334b ​​transmits the received signal to the light-emitting element 335a, and the light-emitting element 335a uses optical principles to illuminate the light source into the prism 335b. The prism 335b refracts the light into the optical conductor 335c, and displays information (or patterns) in the optical conductor 335c, and then projects the information onto the front windshield assembly 10 through the lens 335e; the body controller can determine whether to start the projector regulator 335d based on the clarity of the information projected on the front windshield assembly 10. If the projector regulator 335d is started, the body controller sends a signal to the projector regulator 335d to make it automatically focus to adjust the projection clarity.

[0063] Combination Figure 6 Furthermore, in some embodiments of the present invention, in order to improve the clarity of the instrument projector 331 projected onto the front windshield assembly 10, the material of the front windshield assembly 10 can be changed; specifically, in some embodiments of the present invention, the front windshield assembly 10 includes a first glass 11, a second glass 13 and a third glass 15 which are stacked, the first glass 11 is arranged on a side of the second glass 13 away from the cockpit of the car, and the third glass 15 is arranged on a side of the second glass 13 facing the cockpit of the car; the third glass 15 is used to provide a projection position for the instrument projector assembly 33.

[0064] In this embodiment, the first glass 11 can receive external sunlight. If the external sunlight is too bright or too dark, it will affect the clarity of the information projected by the instrument projector 331 onto the third glass 15. Therefore, in order to maintain the clarity of the information projected by the instrument projector 331 onto the third glass 15, the intensity of the external sunlight needs to be appropriately reduced, but the effect on the brightness of the light inside the cockpit is relatively weak (negligible); for this purpose, a coating of ultraviolet absorber and infrared reflector can be set on the first glass 11; the second glass 13 is to eliminate the ghosting phenomenon of the instrument projector 331 during projection, and it is necessary to use the optical principle of refraction and reflection of light, that is, The second glass 13 needs to have high light transmittance and low reflectivity to ensure that the light of the projector can be efficiently transmitted and reduce unnecessary reflections; therefore, an anti-reflection coating or an anti-scattering coating can be added to the second glass 13; the material of the second glass 13 can also be a PVB resin film; the third glass 15 is used to reflect the light of the instrument projector 331 to the human eye, and its reflected light is soft and clearly visible to reduce damage to the human eye. The third glass 15 needs to have appropriate reflectivity and scattering properties to ensure that the light can be evenly reflected to the human eye, while avoiding glare caused by excessive reflected light; therefore, a diffuse reflection coating can be added to the third glass 15. By arranging the front windshield in layers, and each layer adopts different materials or coatings according to its different effects, the clarity of the information projected onto the front windshield assembly 10 is improved.

[0065] Combination Figures 7 to 10 In some embodiments of the present invention, the automobile further includes a steering wheel controller, a voice controller and a multimedia controller, and the body controller is electrically connected to the steering wheel controller, the voice controller and the multimedia controller.

[0066] In this embodiment, combined with Figure 7 From the above, the instrument projector 331 can be powered on by a one-touch start switch, which can be a one-touch start when the car key is used to start the vehicle. Of course, other buttons can also be set for one-touch start; at the same time, the steering wheel controller, the voice controller and the multimedia controller are all electrically connected to the body controller. The body controller can be understood as a central control system for receiving, transmitting and sending signals. The steering wheel controller can be provided with buttons or other structures to send signals to the body controller. The voice controller can send signals to the multimedia controller by the driver speaking words. The multimedia controller can convey the signal sent by the voice controller to the body controller. At the same time, the driver can also directly operate the multimedia device, such as setting buttons or other structures on the multimedia device to send signals to the body controller. It should be known that the multimedia device includes a multimedia controller (not shown in the figure), and a signal feedback processing module is set between the body controller and the multimedia device. The signal feedback processing module can compare the output signal between the multimedia device and the body controller with the expected input signal by monitoring the output signal between the multimedia device and the body controller, and adjust the output accordingly, so that the multimedia device and the body controller are both in a stable working state.

[0067] After the body controller receives the signal transmitted by the above three methods, the body controller transmits the signal to the signal receiver, the signal receiver transmits the signal to the signal processor for processing, the signal processor transmits the signal to the signal emitter, the signal emitter transmits the signal to the instrument projector 331 to realize function transmission, the instrument projector 331 feeds back the function information to be realized to the multimedia device through the body controller and the information feedback processing module, and the instrument projector 331 projects the required information onto the third glass 15. This setting can integrate multiple controllers together, thereby improving the overall space utilization of the car. At the same time, the above three controllers can adjust the work of the instrument projector 331. Compared with the related art that only the steering wheel controller can adjust the instrument projector 331, the solution of the utility model enhances the optionality of controlling the instrument projector 331, which is more convenient for the driver to operate.

[0068] Furthermore, combined with Figure 7In some embodiments of the present invention, the automobile further includes a multimedia display screen 50, which is disposed on the dashboard panel 31 and spaced apart from the instrument projector assembly 33; the automobile further includes a video processor and an audio regulator both electrically connected to the vehicle body controller; the video processor and the audio regulator are both electrically connected to the multimedia display screen 50, and the multimedia display screen 50 is used to display a variety of different types of data.

[0069] In this embodiment, the multimedia device can also transmit signals to the audio regulator and the video processor through the vehicle body controller. The audio processor is used to adjust the volume of the speaker; the video processor is used to transmit signals to the multimedia display screen 50 and the projector regulator 335d. The multimedia display screen 50 can be used to display the text, video or pattern processed by the video processor; the projector regulator 335d can adjust the clarity of the instrument projector 331; the voice controller and the multimedia device adjust all functions of the multimedia device by voice dialogue. The multimedia display screen 50 and the instrument projector 331 are set apart so that they do not interfere with each other when working.

[0070] It can be known that the multimedia device is electrically connected to the circuit board 334b ​​of the instrument projector 331 through the wire 334a; the multimedia display screen 50 is used to display a variety of different types of data, and the different types of data referred to here include the vehicle driving parameters mentioned above (for example, vehicle speed, remaining fuel, mileage data, water temperature data, light indication, etc.), and the real-time broadcast pattern of map navigation and other data or patterns can also be set. Through such a setting, compared with the traditional interface, the projection adds rich content, making the driver's operation more convenient and safer.

[0071] Furthermore, combined with Fig. 9 and Fig.10 In some embodiments of the utility model, an instrument display area 51, a speed display area 52 and a software display area 53 are arranged at intervals on the multimedia display screen 50; the area projected by the instrument projector assembly 33 to the front windshield assembly 10 includes the instrument display area 51, the speed display area 52 and the software display area 53 arranged at intervals.

[0072] In this embodiment, the display area of ​​the multimedia display screen 50 and the area projected onto the front windshield assembly 10 by the instrument projector 331 can be the same, or can be selected according to the needs of the driver, or can be reflected on the projection area of ​​the instrument projector 331 through the driver's operation on the multimedia display screen 50. In one embodiment of the utility model, the area projected onto the front windshield assembly 10 by the instrument projector assembly 33 includes an instrument parameter display area and a speed display area 52 that are spaced apart.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
