Description

Technical Field

[0001] This utility model relates to the field of vehicle multimedia technology, and in particular to a vehicle navigation display screen that can be flipped up. Background Technology

[0002] Current mainstream in-vehicle navigation displays adopt a fixed vertical installation method. While this structure can stably display navigation maps, traffic information, and other information when the display is in use, meeting the driver's basic needs, it has significant drawbacks when the display is not in use: Firstly, the display surface is constantly exposed to the center console surface, making it prone to dust and fingerprints. Long-term use will lead to a decrease in display clarity. Furthermore, if it is hit or scratched by foreign objects, it is very easy to cause the screen to be scratched or damaged, increasing repair costs. Secondly, under strong light, the exposed display surface will produce strong reflections. These reflections may not only cover the labels of other function buttons on the center console, but also shine directly into the driver's line of sight, interfering with the driver's judgment of road conditions and posing a potential risk of traffic accidents.

[0003] Therefore, it is necessary to propose a new type of in-vehicle navigation display to overcome the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a flip-up vehicle navigation display screen to solve the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the present invention provides a vehicle navigation display screen for flip-over use, comprising: a mounting bracket and a display screen; a motor and a screw driven by the motor are mounted on the mounting bracket on both sides of the screw; a stabilizing rod parallel to the screw is mounted on the mounting bracket; a drive seat threadedly engaged with the screw is mounted on the screw; a stabilizing seat is slidably mounted on the stabilizing rod; both the drive seat and the stabilizing seat are rotatably connected to the bottom edge of the display screen; a limit strip hole and a limit mechanism are provided on the side of the mounting bracket; a limit rod is provided on the side of the display screen; one end of the limit rod is rotatably connected to the side of the display screen, and the other end is provided with a sliding column; the sliding column is slidably mounted in the limit strip hole; when the display screen is in the flip-over state, the limit mechanism holds the sliding column at the front end of the limit strip hole, and releases the lock on the sliding column when the display screen is in the horizontal state.

[0006] Furthermore, the mounting bracket includes a front edge, a rear edge, and two side edges. The front edge and the rear edge are both disposed between the two side edges and are fixedly connected to their respective ends. The limiting strip hole and the limiting mechanism are disposed on the side edge between the front edge and the rear edge, wherein the limiting mechanism is disposed between the limiting strip hole and the front edge.

[0007] Furthermore, the motor is fixedly mounted on the rear end side, the two ends of the screw are rotatably connected to the front end side and the rear end side respectively, and are connected to the output shaft of the motor, and the two ends of the stabilizer are fixedly connected to the front end side and the rear end side respectively.

[0008] Furthermore, the limiting mechanism includes a connecting rod and a stop rod. The stop rod is located at the end of the limiting strip hole, with its middle part rotatably connected to the side. The connecting rod is slidably located on the outside of the side, with one end hinged to the stop rod. A return spring is provided on the connecting rod, with both ends of the return spring connected to the connecting rod and the side respectively. An unlocking mechanism is provided on the side of the other end of the connecting rod. The unlocking mechanism restricts the connecting rod from sliding to the front edge when the display screen is in a flipped state.

[0009] Furthermore, the unlocking mechanism includes an unlocking rod and an unlocking seat. The unlocking seat is fixedly disposed on the inner side of the side, and the unlocking rod is slidably disposed on the unlocking seat. Its upper end passes through the front end edge, and its lower end is provided with a baffle that passes through the side edge. An unlocking spring is provided on the unlocking rod, and the two ends of the unlocking spring are respectively connected to the unlocking rod and the unlocking seat.

[0010] Compared with the prior art, the beneficial effects of this utility model include: 1. This utility model achieves the switching between vertical use and horizontal hiding of the display screen through the cooperation of the drive component and the limiting component. In the horizontal state, the display surface is hidden downwards, which can avoid the damage to the display effect caused by dust accumulation and scratches from foreign objects. At the same time, it eliminates the safety hazard of the display surface reflecting light and interfering with the driver's vision under strong light. Furthermore, through the screw and the stabilizer bar, combined with the sliding cooperation between the stabilizer bar and the stabilizer base, it can prevent the display screen from shaking when flipping, thus improving the stability of use.

[0011] 2. This utility model, through the combined design of the limiting mechanism and the unlocking mechanism, can automatically lock the sliding column when the display screen is in the vertical position, preventing it from retracting along the limiting strip hole and causing the display screen to flip, thus ensuring stable use. The unlocking operation only requires pressing the unlocking rod to release the lock. Combined with the start and stop control of the motor and the position sensing device, the operation is convenient. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] Example 1 This utility model provides a vehicle navigation display screen for flip-up use, including a mounting frame consisting of two parallel side edges 1, a front edge 2 connected to the front end of the side edges 1, and a rear edge 3 connected to the rear end of the side edges 1. The display screen 4 is mounted on the mounting frame, which is fixed to the inside of the vehicle's center console by bolts. The bottom edge of the display screen 4 is rotatably connected to a drive component and a stabilizing component, respectively. The side edges cooperate with the side edges 1 of the mounting frame through limiting components to achieve a flip-up switching from a vertical use state to a horizontal hidden state.

[0015] The drive assembly includes a motor 5, a screw 6, and a drive seat 10. The motor 5 is fixed to the middle of the rear end side 3 of the mounting bracket. The output shaft of the motor 5 is arranged horizontally and forward, and is connected to the rear end of the screw 6 via a coupling. The front end of the screw 6 is rotatably connected to the front end side 2 of the mounting bracket via a bearing. The drive seat 10 has an internal thread that matches the screw 6. The drive seat 10 is sleeved on the screw 6 to form a threaded transmission fit. When the screw 6 rotates, the drive seat 10 can slide back and forth along the axial direction of the screw 6. The stabilizing assembly includes two stabilizing rods 7 and two stabilizing seats 11: the two stabilizing rods 7 are respectively arranged parallel to both sides of the screw 6 and are on the same horizontal plane as the screw 6; the two ends of each stabilizing rod 7 are respectively fixedly connected to the front end 2 and the rear end 3 of the mounting bracket; the stabilizing seats 11 are slidably sleeved on the stabilizing rods 7, and the two stabilizing seats 11 are respectively rotatably connected to the bottom edge of the display screen 4, while the drive seat 10 is also rotatably connected to the middle of the bottom edge of the display screen 4.

[0016] The limiting component includes a limiting strip hole 8 and a limiting rod 9. The limiting strip hole 8 is opened on two sides 1 of the mounting bracket, and the limiting strip holes 8 on the two sides 1 are symmetrically arranged. One end of the limiting rod 9 is rotatably connected to the middle of the side of the display screen 4, and the other end is integrally formed with a cylindrical sliding post 901. The diameter of the sliding post 901 matches the width of the limiting strip hole 8. The sliding post 901 is embedded in the limiting strip hole 8 to form a sliding fit. The trajectory of the sliding post 901 is limited by the limiting strip hole 8, thereby controlling the flip angle of the display screen 4 (which can only switch between vertical and horizontal states).

[0017] Example 2 Based on Embodiment 1, in order to improve the stability of the display screen after flipping (to prevent the slide column 901 from returning along the limiting strip hole 8 after flipping, which would cause the control display screen 4 to flip backward), a limiting mechanism 12 is installed on the side 1, and the end of the slide column 901 protrudes out of the limiting strip hole 8.

[0018] The limiting mechanism 12 is located between the limiting strip hole 8 and the front end edge 2, and includes a connecting rod 13, a stop rod 14, a return spring 15, and an unlocking mechanism: the middle part of the stop rod 14 is rotatably connected to the side edge 1 through a pin, the upper end of the stop rod 14 protrudes from the lower edge of the limiting strip hole 8 (to block the sliding column 901), and the other end is hinged to one end of the connecting rod 13 (specifically: the lower end of the stop rod 14 is provided with a strip hole along the length direction, and the connecting rod 13 is provided with a connecting post that cooperates with the strip hole on the stop rod 14); the connecting rod 13 is slidably mounted on the side edge 1 along its length direction; one end of the return spring 15 is connected to the connecting rod 13, and the other end is connected to the side edge 1, and the return spring 15 is in a free state under normal conditions.

[0019] The unlocking mechanism includes an unlocking rod 16, a baffle 17, an unlocking seat 18, and an unlocking spring 19. The unlocking seat 18 is fixed to the inner side of the side 1, and a vertically penetrating sliding hole is provided on the unlocking seat 18. The unlocking rod 16 is a cylindrical rod that passes through the sliding hole of the unlocking seat 18 and slides with the unlocking seat 18. The upper end of the unlocking rod 16 passes through the front end edge 2 of the mounting bracket, and the lower end is integrally formed with a horizontally arranged baffle 17. The baffle 17 passes through an elongated hole on the side 1 (the elongated hole corresponds to the position of the connecting rod 13) and can contact the end of the connecting rod 13 away from the stop bar 14. The unlocking spring 19 is sleeved on the unlocking rod 16 and can push the unlocking rod 16 to return to its original position.

[0020] To facilitate understanding of this utility model, the following is combined with... Figure 1 - Figure 2 The working principle of this solution will be explained in detail: When the display screen 4 needs to be used in a vertical position, the motor 5 starts and drives the screw 6 to rotate forward. The screw 6 drives the drive seat 10 to slide forward along the screw 6, and the drive seat pushes the bottom edge of the display screen 4 forward. At the same time, the limiting rod 9 on the side of the display screen 4 moves with the display screen 4, and the sliding column 901 slides forward along the limiting strip hole 8. When the sliding column 901 moves to the front end of the limiting strip hole 8, it presses down the stop rod 14. After the sliding column 901 passes the stop rod 14, the stop rod 14 is reset by the action of the return spring 15. When the display screen 4 rotates to the vertical position, the pressing state of the unlocking rod 16 is released, and the baffle 17 rises and aligns with the connecting rod 13 to prevent it from sliding to the front end 2, thereby keeping the sliding column 901 at the front end of the limiting strip hole 8. After the display screen 4 rotates to the vertical position, the motor 5 stops working (in actual applications, the start and stop control of the motor 5 can be realized through the control circuit and the position sensing device).

[0021] When the display screen 4 needs to be flipped to a horizontal position for hiding, the motor 5 rotates in the opposite direction. Since the slide bar 901 is held at the front end of the limiting strip hole 8, the display screen 4 first flips to a horizontal position, and its side presses down the unlocking rod 16 to release the restriction on the connecting rod 13. The slide bar 901 then presses down the stop bar 14 in the opposite direction and slides backward along the limiting strip hole 8, and the display screen 4 retracts horizontally.

[0022] A cover 20 can be installed on the top of the two sides 1 to reduce the entry of foreign objects when the display screen 4 is in a vertical state, while keeping the display screen 4 stable when sliding in and out in a horizontal state.

[0023] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
