[0001] This utility model relates to the field of vehicle navigation system assembly technology, specifically to a screen mounting device for a vehicle navigation system. Background Technology

[0002] A car navigation system is a driving assistance device that helps users accurately locate their current position and calculate the journey based on a predetermined destination. It guides users to their destination through map display and voice prompts. In many current car designs, the screen of the car navigation system is typically embedded manually into the navigation unit's casing. However, manual installation involves multiple steps, including positioning, alignment, and securing, which is time-consuming and impacts car production efficiency. Furthermore, car screens typically have a certain weight and size, making them susceptible to bumps and knocks during manual handling, leading to accidental damage. Utility Model Content

[0003] The purpose of this invention is to design a screen mounting device for a vehicle navigation system, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A screen mounting device for a vehicle navigation system includes a frame. A crossbar is located at the top of the frame. A vehicle screen conveying system and a navigation system housing conveying system are respectively located below both ends of the crossbar. A horizontal moving mechanism is located at the bottom of the crossbar. A lifting unit is installed at the moving end of the horizontal moving mechanism. A frame is installed at the lifting end of the lifting unit. Vacuum suction cups are located at the four corners of the bottom of the frame. A rectangular through-hole is located in the center of the bottom of the frame. Push rods with vertical sliding cooperation are located at the four corners of the rectangular through-hole. A cylinder is located at the top inside the frame. The push rods are connected to the output end of the cylinder via connecting rods. A positioning mechanism for positioning the vehicle screen is located at one end of the crossbar. The positioning mechanism is located above the navigation system housing conveying system and is electrically connected to the horizontal moving mechanism via a controller.

[0006] Furthermore, the horizontal moving mechanism includes a moving block and two support blocks. The moving block is slidably connected to the bottom of the crossbar, and the support blocks are fixed to the bottom of the crossbar. A first screw is rotatably connected between the two support blocks. The moving block is provided with a threaded hole that is threaded to the first screw. One end of the first screw passes through one of the support blocks and is fixedly connected to a first servo motor.

[0007] Furthermore, the bottom of the crossbar is provided with a groove, and the top of the movable block is provided with a slider that slides in cooperation with the groove.

[0008] Furthermore, the lifting unit is a hydraulic cylinder.

[0009] Furthermore, the push rod has a cylindrical structure, and the four corners of the rectangular through hole are rounded to cooperate with the push rod.

[0010] Furthermore, the bottom of the push rod is provided with a rubber pad.

[0011] Furthermore, the positioning mechanism includes two support frames fixed on opposite sides of the crossbar. One of the support frames is fixedly connected to the bottom of two laser emitters arranged sequentially along the width direction of the vehicle screen, and the other support frame is fixedly connected to the bottom of two laser receivers corresponding to the two laser emitters.

[0012] Furthermore, a horizontal plate is fixedly connected to the bottom of each of the two support frames, and two support plates are fixedly connected to the sides of the horizontal plates. A second screw is rotatably connected between the two support plates. A through sliding hole is provided on the side of the horizontal plate, and two sliding rods are slidably fitted inside the sliding hole. One of the sliding rods is provided with a forward-rotating threaded hole that is threaded with the second screw, and the other sliding rod is provided with a reverse-rotating threaded hole that is threaded with the second screw. One end of the second screw passes through one of the support plates and is fixedly connected to a second servo motor. Two laser emitters are respectively installed on the two sliding rods of one of the horizontal plates, and two laser receivers are respectively installed on the two sliding rods of the other horizontal plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] The lifting unit lowers the frame, allowing the vacuum suction cup at the bottom of the frame to adhere and fix the vehicle screen. Then, the horizontal moving mechanism moves the vehicle screen to the vicinity of the installation position. The positioning mechanism then detects the position of the vehicle screen and sends a signal back to the controller. The controller controls the horizontal moving mechanism to adjust so that the vehicle screen is aligned with the installation position of the navigation device housing. Finally, after the lifting unit lowers the vehicle screen to the set position, the vacuum suction cup releases, and the cylinder inside the frame drives the push rod to push the vehicle screen into the navigation device housing. This achieves efficient and precise installation of the vehicle screen, improves automobile production efficiency, prevents the vehicle screen from being bumped, and avoids accidental damage to the vehicle screen.

Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-4As shown, a screen mounting device for a vehicle navigation system includes a frame 1. A crossbar 2 is provided at the top of the frame 1. A vehicle screen conveying system 25 and a navigation system housing conveying system 26 are respectively located below both ends of the crossbar 2. The vehicle screen conveying system 25 is used to transport the vehicle screen 27, and the navigation system housing conveying system 26 is used to transport the navigation system housing 28. A horizontal moving mechanism is provided at the bottom of the crossbar 2. A lifting unit is installed at the moving end of the horizontal moving mechanism, and a frame 3 is installed at the lifting end of the lifting unit. Through the horizontal moving mechanism and the lifting unit, the frame 3 can be moved horizontally and vertically. Vacuum suction cups 4 are provided at the four corners of the bottom of the frame 3. The vacuum suction cup 4 is connected to the vacuum pump via an air pipe, allowing the vacuum suction cup 4 to adsorb and fix the vehicle screen 27. A rectangular through hole 5 is provided in the middle of the bottom of the frame 3, and push rods 6 with vertical sliding cooperation are provided at the four corners of the rectangular through hole 5, which can improve the stability of the push rods 6 sliding up and down. A cylinder 7 is provided at the top inside the frame 3. The push rods 6 are connected to the output end of the cylinder 7 via a connecting rod. The cylinder 7 drives the push rods 6 to move up and down, thereby pushing the vehicle screen. A positioning mechanism for positioning the vehicle screen 27 is provided at one end of the crossbar 2. The positioning mechanism is located above the navigation device housing transmission system and is electrically connected to the horizontal movement mechanism via a controller.

[0024] The horizontal moving mechanism includes a moving block 8 and two support blocks 9. The bottom of the crossbar 2 is provided with a groove 12, and the top of the moving block 8 is provided with a slider 13 that slides in cooperation with the groove 12. The support blocks 9 are fixed on the bottom of the crossbar 2. A first screw 10 is rotatably connected between the two support blocks 9. The moving block 8 is provided with a threaded hole that is threaded in cooperation with the first screw 10. One end of the first screw 10 passes through one of the support blocks 9 and is fixedly connected to a first servo motor 11. The first servo motor 11 drives the first screw 10 to rotate, so that the slider 13 threaded in connection with the first screw 10 can move along the length direction of the groove 12. The lifting unit is a hydraulic cylinder 14. The cylinder body of the hydraulic cylinder 14 is fixed on the bottom of the slider 13, and the top of the frame 3 is fixed on the output end of the hydraulic cylinder 14.

[0025] The push rod 6 has a cylindrical structure, and the four corners of the rectangular through hole 5 are rounded to fit the push rod 6. The bottom of the push rod 6 is provided with a rubber pad 15 to cushion the impact and prevent damage to the vehicle screen 27.

[0026] The positioning mechanism includes two support frames 16 fixed on opposite sides of the crossbar 2. A cross plate 19 is fixedly connected to the bottom of each support frame 16. Two support plates 20 are fixedly connected to the sides of the cross plate 19. A second screw 21 is rotatably connected between the two support plates 20. A through sliding hole 22 is provided on the side of the cross plate 19. Two sliding rods 23 are slidably fitted inside the sliding hole 22. One sliding rod 23 has a forward-rotating threaded hole that engages with the second screw 21, and the other sliding rod 23 has a reverse-rotating threaded hole that engages with the second screw 21. One end of the second screw 21 passes through one of the support plates 20 and is fixedly connected to a second servo motor 24. Laser emitters 17 are fixedly connected to both sliding rods 23 of one cross plate 19, and the two laser emitters 17 are arranged sequentially along the width direction of the vehicle screen 27. Laser receivers 18 are fixedly connected to both sliding rods 23 of the other cross plate 19, with each laser receiver 18 corresponding to one of the two laser emitters 17. Correspondingly, the distance between the emission ports of the two laser emitters 17 is equal to the width of the vehicle screen 27. When the vehicle screen 27 moves to the position between the beams emitted by the two laser emitters 17, if the laser signal received by the laser receiver 18 is deviated, it means that the position of the vehicle screen 27 needs to be adjusted. The laser receiver 18 will feed the signal back to the controller, and the controller will control the first servo motor 11 to start and adjust the control slider 13 until the laser receiver 18 can receive a normal laser signal, so as to accurately locate the position of the vehicle screen 27. The second servo motor 24 can drive the second screw 21 to rotate, so that the two slide rods 23 threadedly connected to the second screw 21 can move in the sliding hole 22 in the direction of approaching or moving away from each other, thereby adjusting the distance between the two laser generators 17 and the distance between the two laser receivers 18. This method can be applied to the positioning of vehicle screens 27 of different sizes.

[0027] The controller is fixed to the top of the crossbar 2. The vacuum pump, cylinder 7, first servo motor 11, hydraulic cylinder 14, second servo motor 24, light emitter 17 and laser receiver 18 are all electrically connected to the controller. The controller controls the various electrical components to work in coordination.

[0028] Working principle:

[0029] like Figure 1-4As shown, when the screen mounting device is in use, the first servo motor 11 drives the first screw 10 to rotate, causing the slider 13 to move above the vehicle screen conveying system 25. Then, the hydraulic cylinder 14 drives the frame 3 to descend to a suitable height, and the vacuum suction cup 4 will adsorb and fix the vehicle screen 27. Then, the hydraulic cylinder 14 drives the frame 3 to rise and return to its original height. After that, the first servo motor 11 drives the first screw 10 to rotate, causing the slider 13 to move above the navigation device housing conveying system 26, so that the vehicle screen 27 is near the installation position (near the position between the beams emitted by the two laser emitters 17). If the laser signal received by the laser receiver 18 is deviated, it means that the position of the vehicle screen 27 needs to be adjusted. During adjustment, the laser receiver 18 feeds back the signal to the controller, which then controls the first servo motor 11 to start and adjust the slider 13 until the laser receiver 18 can receive a normal laser signal. This allows for precise positioning of the vehicle screen 27, aligning it with the mounting opening of the navigation device housing 28. Then, the hydraulic cylinder 14 lowers the frame 3 to a suitable height, and the vacuum suction cup 4 releases the vehicle screen 27. Simultaneously, the cylinder 7 moves the push rod 6 downwards, allowing the push rod 6 to push the vehicle screen 27 into the navigation device housing 28. This achieves efficient and precise installation of the vehicle screen, improves automotive production efficiency, prevents collisions with the vehicle screen, and avoids accidental damage to the vehicle screen.
