Description

Technical Field

[0001] This utility model relates to the field of automotive electronic equipment installation technology, and in particular to an anti-loosening fixing structure for vehicle navigation systems. Background Technology

[0002] As a commonly used electronic device in cars, in-vehicle navigation provides drivers with important information such as route guidance while the vehicle is in motion. Its fixed stability directly affects the user experience and safety.

[0003] Currently, common methods for fixing in-vehicle navigation systems have many shortcomings. Clip-on fixing structures are prone to wear or deformation after long-term bumpy driving, leading to loosening or even detachment of the navigation system. While screw-on fixing is initially more stable, the screws are prone to stripping after repeated disassembly and assembly, and may gradually loosen under vibration, affecting the fixing effect and reducing the secureness of the in-vehicle navigation system. Therefore, an anti-loosening fixing structure for in-vehicle navigation systems has been proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-loosening fixing structure for vehicle navigation systems, so as to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a vehicle navigation anti-loosening fixing structure, including a positioning frame, a friction shaft with friction rotation at the bottom of the positioning frame, a guide plate fixedly installed at one end of the friction shaft, and the guide plate slidably connected to the inside of an adjusting column, an installation plate fixedly connected at one end of the adjusting column, the installation plate fixedly connected to the vehicle central control unit, an installation sleeve provided on both the upper and lower sides of the outer wall of the positioning frame, and a limit plate fixedly installed on the outer wall of each installation sleeve, a clamping structure provided on the outer side of each of the two limit plates, the clamping structure including an upper clamping plate, a lower clamping plate provided below the upper clamping plate, a clamping claw symmetrically fixedly installed on one end of the outer wall of both the upper and lower clamping plates, and an electric push rod provided on both sides of the outer wall of the upper clamping plate, with one end of the electric push rod connected to the lower clamping plate.

[0006] As a preferred embodiment of the above technical solution, a magnetic absorbing sheet is fixedly attached to the outer wall of the upper clamping plate, and a navigation display screen is provided on the outer side of the magnetic absorbing sheet. The two sets of clamps are adapted to the size of the navigation display screen.

[0007] As a preferred embodiment of the above technical solution, limit sliders are fixedly installed on both sides of the outer wall of the lower clamping plate, and the limit sliders are slidably connected inside the upper clamping plate. Two protrusions are symmetrically installed on the outer wall of the lower clamping plate.

[0008] As a preferred embodiment of the above technical solution, two sets of positioning blocks are fixedly installed on both sides of the outer wall of the upper clamping plate, the electric push rod is fixedly installed inside the positioning block, and one end of the electric push rod is connected to the protrusion.

[0009] As a preferred embodiment of the above technical solution, the guide plate has an installation groove on its outer wall, the adjusting column is threaded with a first locking screw and one end of the first locking screw is connected to the inside of the installation groove, and the two installation sleeves are threaded with a second locking screw and one end of the second locking screw is connected to the positioning frame.

[0010] As a preferred embodiment of the above technical solution, the outer walls of both limiting plates are provided with multiple equidistant positioning holes, the outer wall of the upper clamping plate is fixedly mounted with an mounting plate, and the outer side of the limiting plate is provided with two third locking screws, the outer wall of the third locking screws is threaded into the positioning holes and the extended end is connected to the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device is equipped with a clamping structure. By placing the navigation display screen on the outer wall of the upper clamping plate, it is initially fixed by magnetic adsorption. Then, the lower clamping plate on the protrusion is moved upward by the electric push rod to clamp and limit the navigation display screen with the claws. This makes it easy to fix vehicle navigation display screens of different sizes, avoiding the problems of loosening caused by multiple disassembly and assembly due to traditional bolt fixing. It effectively prevents the navigation from loosening or falling off when the vehicle is bumpy, improves the fixing effect of the vehicle navigation display screen, and makes the disassembly and assembly of the vehicle navigation display screen relatively convenient.

[0013] By pulling the guide plate and sliding it to the appropriate distance on the adjusting column, the guide plate is positioned using the first locking screw. Then, the two mounting sleeves on the positioning frame are rotated, and the mounting sleeves are positioned using the second locking screw. The two upper jaws of the upper clamping plate are slid onto the limiting plate. When the upper clamping plate is moved to the appropriate distance, the two third locking screws are rotated to lock the rear mounting plate of the upper clamping plate into the positioning hole. This facilitates the adjustment of the positions of the two clamping plates, enabling flexible multi-angle adjustment of the vehicle navigation display screen. This adapts to different users, improves the versatility of the fixing structure, and meets the best viewing experience of different users for the navigation display screen.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, the vehicle navigation anti-loosening fixing structure provided in this embodiment includes a positioning frame 1. The bottom of the positioning frame 1 has a friction rotating shaft 3, and one end of the friction rotating shaft 3 is fixedly installed with a guide plate 72. The guide plate 72 is slidably connected to the inside of the adjusting column 7. One end of the adjusting column 7 is fixedly connected to an installation plate 2. The installation plate 2 is fixedly connected to the vehicle's central control unit. The upper and lower sides of the outer wall of the positioning frame 1 are provided with installation sleeves 5, and the outer walls of the installation sleeves 5 are fixedly installed with limit plates 52. The outer sides of the two limit plates 52 are provided with clamping structures 4. The clamping structures 4 include an upper clamping plate 41 and a lower clamping plate 42 below the upper clamping plate 41. One end of the outer wall of the upper clamping plate 41 and the lower clamping plate 42 are symmetrically fixedly installed with claws 43. Both sides of the outer wall of the upper clamping plate 41 are provided with electric push rods 47, and one end of the electric push rods 47 is connected to the lower clamping plate 42.

[0024] like Figures 2 to 3As shown, a magnetic suction plate 44 is fixedly attached to the outer wall of the upper clamping plate 41, and a navigation display screen 6 is provided on the outer side of the magnetic suction plate 44. The two sets of grippers 43 are adapted to the size of the navigation display screen 6. Limiting sliders 45 are fixedly installed on both sides of the outer wall of the lower clamping plate 42, and the limiting sliders 45 are slidably connected to the inside of the upper clamping plate 41. Two protrusions 48 are symmetrically installed on the outer wall of the lower clamping plate 42. Two sets of positioning blocks 46 are fixedly installed on both sides of the outer wall of the upper clamping plate 41. An electric push rod 47 is fixedly installed inside the positioning block 46, and one end of the electric push rod 47 is connected to the protrusion 48.

[0025] By placing the vehicle navigation display screen 6 between two clamping plates, and then driving the two electric push rods 47 to move the lower clamping plate 42 on the protrusion 48 upward to clamp and position the display screen, the lower clamping plate 42 slides inside the upper clamping plate 41 using the outer wall limiting slider 45, which facilitates the fixed installation of navigation display screens 6 of different sizes and makes disassembly relatively convenient.

[0026] like Figures 4 to 5 As shown, the guide plate 72 has an installation groove 73 on its outer wall. The adjusting column 7 is threaded with a first locking screw 71, and the first locking screw 71 is pressed into the installation groove 73. The two installation sleeves 5 are threaded with a second locking screw 51, and one end of the second locking screw 51 is connected to the positioning frame 1. The outer walls of the two limiting plates 52 are provided with multiple equidistant positioning holes 53. The upper clamping plate 41 is fixedly installed with an installation plate 55. The outer side of the limiting plate 52 is provided with two third locking screws 54, and the outer wall of the third locking screw 54 is threaded into the positioning hole 53 and the extended end is connected to the installation plate 55.

[0027] By sliding the guide plate 72 within the adjusting column 7, the positioning frame 1 can be adjusted in the front and rear distance. By rotating the mounting sleeve 5, the vehicle navigation display screen 6 can be adjusted in all directions. At the same time, the positions of the two sets of clamps can be adjusted to facilitate the installation of vehicle navigation display screens 6 of different sizes, thus improving the adaptability of the fixing structure.

[0028] The working principle and process of this utility model are as follows: First, the operator fixes the mounting plate 2 to the vehicle's central control unit with bolts. When it is necessary to place the navigation display screen 6, the electric push rods 47 on the two sets of positioning blocks 46 on the outer wall of the upper clamping plate 41 are activated. This causes the two electric push rods 47 to drive the lower clamping plate 42 on the protrusion 48 to move downward. At the same time, the lower clamping plate 42 slides with the help of the outer wall limiting slider 45, which makes it easy to adjust the distance between the upper clamping plate 41 and the lower clamping plate 42 to a suitable size according to the size of the navigation display screen 6. Then, the navigation display screen 6 is placed on the outer wall of the upper clamping plate 41 and is initially fixed by magnetic adsorption 44. Then, the lower clamping plate 42 on the protrusion 48 is moved upward by the electric push rods 47 to clamp and limit the navigation display screen 6 with the claws 43. This makes it easy to fix the vehicle navigation display screen 6 of different sizes, avoiding the problems of loosening caused by multiple disassembly and assembly caused by traditional bolt fixing, and improving the fixing effect of the vehicle navigation display screen 6.

[0029] When the driver cannot see the in-vehicle navigation display screen 6 due to height limitations, the guide plate 72 is slid along the adjusting column 7 to a suitable distance. Then, the guide plate 72 is positioned using the first locking screw 71. Next, the two mounting sleeves 5 on the positioning bracket 1 are rotated. When the rotation reaches a suitable angle, the mounting sleeves 5 are positioned using the second locking screw 51. Simultaneously, when the in-vehicle navigation display screen 6 has different sizes, the two clamping claws 43 at the upper end of the upper clamping plate 41 are slid onto the limiting plate 52 by rotating the display screen size. When the screen is moved to a suitable distance, the two third locking screws 54 are rotated to lock the mounting plate 55 on the rear side of the upper clamping plate 41 into the positioning hole 53. This facilitates the adjustment of the positions of the clamping plates on both sides, enabling flexible multi-angle adjustment of the in-vehicle navigation display screen 6 to adapt to different users and improve the versatility of the fixing structure.
