Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted navigation, and more particularly to a vehicle-mounted combined navigation device. Background Art

[0002] With the rapid development of smart cars, in-vehicle navigation devices have gradually changed from navigation on the central control display screen to navigation on the head-up display, allowing drivers to move the direction of observing navigation information from sideways viewing to viewing directly in front of the windshield, further improving driving safety.

[0003] However, in real driving accidents, there are still cases where drivers are distracted during driving, or turn their heads to chat with people in the car or pick up objects, or their eyes are not focused on the road, leading to safety accidents (such as emergency braking due to missing the route). The main reasons include the following two behavioral habits: first, the driver's head turns passively, causing his eyes to be separated from the navigation information; second, the driver's eyes are not actively focused on the navigation information due to the environment outside the car.

[0004] Analyzing the above-mentioned common causes of accidents, it can be simply concluded that the current head-up display is not enough to keep the navigation information in the driver's sight. The navigation information can be combined with human body dynamics to focus on the front of the human eye to further improve driving safety. For example, wearing smart glasses or VR glasses can always display the navigation information on the front of the glasses. In this way, the display of navigation information will not be missed due to the driver's head turning or line of sight deviation. In view of this, we propose a vehicle-mounted combined navigation device. Summary of the invention

[0039] like Figures 1 to 10 As shown, the present invention relates to a vehicle-mounted combined navigation device, comprising a storage device 1 which can be embedded and installed on a vehicle-mounted center console, and a navigation pair of glasses 2 is movably placed in the storage device 1 .

[0040] like Figure 2As shown, the navigation glasses 2 in the present invention include a main body 201, a communication module, a projection module 202 and a wireless charging receiving module 203; the communication module is arranged inside the main body 201, and is used to connect to the navigation server to obtain route image information of the navigation road condition; the projection module 202 is arranged at the front of the main body 201, and is connected to the communication module signal, and is used to display the navigation road condition image information; the wireless charging receiving module 203 is arranged at the rear of the main body 201, and is used to power the communication module and the projection module 202; it is worth noting that the specific structural shape of the navigation glasses 2 is similar to that of Google Glass in the prior art, the projection module 202 is specifically a head-mounted micro display screen, which can project data onto a small screen above the user's right eye, and the wireless charging receiving module 203 is arranged at the rear of the main body 201, and is used to power the glasses, and its charging method is the wireless charging technology based on the electromagnetic induction principle in the prior art.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the storage device 1 includes a shell 3, a carrier plate 4 is fixedly installed in the shell 3, and a glasses seat 5 is slidably connected to the upper surface of the carrier plate 4 in a radial structure through a linear drive mechanism 8, and the navigation glasses 2 are movably placed on the glasses seat 5. A pressing seat 6 is slidably connected to the outer side of the carrier plate 4 in an axial structure through a screw drive mechanism 9, and the pressing seat 6 is in active contact with the navigation glasses 2. A wireless charging transmitter unit 7 is slidably connected to the inner side of the carrier plate 4 in a radial structure, and the wireless charging transmitter unit 7 is in active contact with the wireless charging receiving module 203. Specifically, as Figure 1 As shown, a cover plate 301 is hingedly connected to the front of the shell 3 along the direction in which the glasses holder 5 slides out, which is used to prevent the opening of the shell 3 from being exposed to the air for a long time, thereby reducing dust; further, a placement groove 501 adapted to the structure of the navigation glasses 2 is provided on the glasses holder 5, and an avoidance groove 502 is provided in the placement groove 501 relative to the position of the wireless charging transmitter unit 7, so as to provide a movable space for the subsequent mobile charging of the wireless charging transmitter unit 7. Further, as Figure 5 As shown, the pressing seat 6 is in a U-shaped structure and is slidably connected to the edge of the carrier plate 4 via a guide protrusion 601 .

[0042] As an embodiment of the present invention, Figure 6 and Figure 7As shown, in order to understand how the wireless charging transmitter module 703 is in active contact with the wireless charging receiver module 203, the present invention discloses the specific structure of the wireless charging transmitter unit 7, which includes a mounting seat 701 fixed to the inner side of the carrier 4, a guide plate 702 arranged above the mounting seat 701, a wireless charging transmitter module 703 fixedly connected to the upper surface of the guide plate 702, a wireless charging transmitter coil inside the wireless charging transmitter module 703, the wireless charging transmitter module 703 is in active contact with the wireless charging receiver module 203, a wireless charging receiver coil inside the wireless charging receiver module 203, and the two transmit electric energy through electromagnetic induction. The lower surface of the guide plate 702 is movably connected to a connecting seat 704 through a guide structure 10. It is worth mentioning that the present invention discloses a specific structure of the guide structure 10, which includes an axial protrusion 1001 and a radial groove 1002; the axial protrusion 1001 is fixedly arranged on one side of the lower surface of the guide plate 702, and the axial protrusion 1001 is slidably connected to the axial groove 7041 on the upper surface of the connecting seat 704; the radial groove 1002 is opened on the lower surface of the guide plate 702 relative to the position of the guide rod 709, and the radial groove 1002 includes a straight segment and an arc segment, the arc segment is arranged at the tail end of the straight segment, and the bending direction of the arc segment is away from the wireless charging receiving module 203, so that when the guide plate 702 moves toward the tail end of the mounting seat 701, when the guide rod 709 enters the arc segment from the straight segment, it is restricted by the linear movement of the guide rod 709, and the arc segment forces the guide plate 702 to move horizontally to one side in the opposite direction, thereby facilitating the active fitting of the wireless charging transmitting module 703 and the wireless charging receiving module 203.

[0043] In addition, in order to reduce the hard contact between the wireless charging transmitter module 703 and the wireless charging receiver module 203, in the present invention, two buffer seats 705 are arranged in a symmetrical structure on both sides of the axial direction of the connecting seat 704. The upper surface of the buffer seat 705 is elastically connected to the connecting seat 704 through a displacement spring 706, and the lower surface of the buffer seat 705 is slidably connected to the mounting seat 701 through a linear guide rod 707. An extension plate 708 is arranged below the mounting seat 701, and a guide rod 709 is erected in the middle of the extension plate 708. A motor A710 is fixed on the side of the extension plate 708. The head end of the motor A710 is fixedly passed through the mounting seat 701 and is connected to a driving wheel A711. The outer side of the driving wheel A711 is connected to a driving wheel B712 in a transmission manner. The driving wheel B712 is in friction contact with the surface of one of the buffer seats 705. The working principle of wireless charging: the motor A710 is used to rotate and drive the driving wheel A711, and the driving wheel A711 drives the driving wheel B712, so that the buffer seat 705 in contact with the driving wheel B712 can move linearly along the linear guide rod 707. When the guide rod 709 enters the arc segment from the straight segment, it is restricted by the linear movement of the guide rod 709, and the arc segment forces the guide plate 702 to move sideways in the opposite direction, which is conducive to the active fit of the wireless charging transmitting module 703 and the wireless charging receiving module 203.

[0044] As an embodiment of the present invention, Fig.10 As shown, in order to understand how the glasses holder 5 is extended from the shell 3, the present invention discloses the specific structure of the linear drive mechanism 8, which includes a motor B801 fixedly mounted on the head end of the carrier plate 4, and the output end of the motor B801 is connected to the driving wheel C803 through a synchronous wheel set 802 (including a synchronous wheel, a transmission belt and a driven wheel), and the driving wheel C803 is in frictional contact with the glasses holder 5; a resistance wheel 804 is coaxially connected below the driving wheel C803, and a stress block 805 is movably connected to the outer side of the resistance wheel 804, and the stress block 805 is elastically connected to the carrier plate 4 through a torsion spring; a resistance rod 806 is fixedly connected to the side of the stress block 805 close to the resistance wheel 804, and the resistance rod 806 is movably engaged with a groove 807 on the circumference of the resistance wheel 804. The action principle of extending the glasses holder 5: when the motor B801 is running, the driving wheel C803 is driven by the synchronous wheel set 802, so that during the rotation of the driving wheel C803, the glasses holder 5 is driven to extend out of the shell 3 through friction. It is worth noting that the glasses holder 5 is a shell with a hollow bottom, and the circumferential length of the driving wheel C803 is a multiple of the extended length of the glasses holder 5, either 1 times or 2 times, and can be arranged according to the specific implementation environment of the center console. In addition, in order to improve the stability of the structure of the glasses holder 5 after it is extended and retracted, the present invention is also coaxially connected with a resistance wheel 804 under the driving wheel C803, and the groove 807 on the resistance wheel 804 is movably engaged with the reset rotating resistance rod 806 to provide temporary resistance and ensure the stability of the glasses holder 5.

[0045] As an embodiment of the present invention, the present invention discloses a specific structure of a screw drive mechanism 9, which includes a motor C901, a screw 902 and a screw sleeve 903; the motor C901 is fixed on the carrier plate 4 relative to the avoidance groove 502, the screw 902 is fixed on the output end of the motor C901, the screw sleeve 903 is fixed on the pressing seat 6, and the screw 902 is threadedly connected to the screw sleeve 903. In order to improve the charging stability of the navigation glasses 2 on the glasses seat 5, the present invention uses the motor C901 to drive the screw 902 to rotate, so that the screw sleeve 903 threadedly connected to the screw 902 drives the pressing seat 6 to linearly descend along the guide protrusion 601, thereby pressing down and fitting on the glasses seat 5.

[0046] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
