Technical Field

[0001] The utility model relates to the technical field of navigation instruments, in particular to a support frame for navigation instruments. Background Art

[0002] As an indispensable technological product in modern society, the importance of navigation instruments is self-evident. They play a vital role in many fields such as transportation, surveying and mapping, ocean, and military. Although their working principles and functions are different, their common goal is very clear, that is, to determine the location, navigation path, and provide location-related data. Navigation instruments need to be installed when in use, which brings about an important demand: navigation instrument support frame. This support frame can fix the navigation instrument to ensure its stable operation in various environments. Factors that need to be considered in the design and selection of navigation instrument support frames include: stability, durability, portability, and compatibility with navigation instruments. A high-quality navigation instrument support frame can provide users with a more convenient use experience while ensuring the accuracy and safety of the navigation instrument.

[0003] After searching, the publication number CN214583309U discloses an electronic navigation device for vehicle-road cooperative driving of networked vehicles, including a pad, a display and a support frame. The upper surface of the pad is movably connected to the display, and the support frame is fixedly installed at one end of the upper surface of the pad close to the display.

The inner wall of the support frame is fixed with a limit block, and the outer surface of the limit block is slidably connected to the inner wall of the slider. The upper surface of the support frame is threadedly connected to a support rod, and the end of the support rod away from the support frame is rotatably connected to a placement frame, and the bottom end of the placement frame is slidably connected to a slide plate. This utility model solves the problem that most of the traditional navigators are supported on the center console by a bracket, and if the car brakes suddenly or bumps during use, the navigator will fall off the surface of the bracket. This application only solves the problem that the navigator is supported on the center console by a bracket, and if the car brakes suddenly or bumps during use, the navigator will fall off the surface of the bracket, but the display angle of the navigation instrument cannot be adjusted, which is inconvenient to use.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Reference Figure 1-3 , the utility model provides an embodiment: a support frame for a navigation instrument, comprising a base plate 1, the outer wall of the base plate 1 is fixedly connected to a support block 2, the outer wall of the base plate 1 is fixedly connected to a suction cup 3, the outer wall of the support block 2 is rotatably connected to a connecting block 5, a push tube 4 is arranged inside the connecting block 5, the outer wall of the push tube 4 is fixedly connected to a toothed disc 2 10, the inner sliding connection of the toothed disc 2 10 is provided with a limiting rod 12, the outer wall of the limiting rod 12 is fixedly connected to the inner wall of the support block 2, the outer wall of the limiting rod 12 is sleeved with a spring 11, one end of the spring 11 is fixedly connected to the outer wall of the support block 2, the other end of the spring 11 is fixedly connected to the outer wall of the toothed disc 2 10, the inner wall of the connecting block 5 is fixedly connected to a support tube 8, the outer wall of the support tube 8 is fixedly connected to a toothed disc 1 9, the outer wall of the toothed disc 1 9 is fixedly connected to the inner wall of the connecting block 5, the outer wall of the limiting rod 12 is fixedly connected to the outer wall of the connecting block 5, a bolt 7 is arranged inside the connecting block 5, a fixing block 6 is arranged on the outer wall of the bolt 7, and a fixing component is arranged on the outer wall of the connecting block 5;

[0024] Specifically, during the adjustment process, first press the push cylinder 4 to move the toothed disc 2 10 inside the support block 2. The design of the push cylinder 4 allows it to push the toothed disc 2 10 smoothly, thereby achieving angle adjustment. At the same time, the limit rod 12 plays a limiting role to prevent the toothed disc 2 10 from shifting during movement, thereby ensuring the accuracy of the adjustment. Next, the operator needs to rotate the connecting block 5, which is connected to the toothed disc 2 10, and drives the carrier plate 13 to move through its movement. This design makes the adjustment process smoother and ensures the accuracy of the angle adjustment. After the adjustment is completed, the operator needs to release the push cylinder 4. At this time, the limit rod 12 will push the toothed disc 2 10 to be stuck on the toothed disc 1 9. The purpose of this step is to fix the positions of the support block 2 and the connecting block 5 to ensure that the adjusted angle will not change. In short, this adjustment system achieves precise adjustment of the instrument angle through the synergistic effect of various components.

[0025] Reference Figure 4The fixed component includes a carrier plate 13, the outer wall of the carrier plate 13 is fixedly connected to the outer wall of the fixed block 6, and the inside of the carrier plate 13 is rotatably connected to a worm 16; the inside of the carrier plate 13 is rotatably connected to a worm wheel 17, and the worm wheel 17 and the worm 16 are meshed; the outer wall of the worm wheel 17 is fixedly connected to a gear 18, and the outer wall of the gear 18 is rotatably connected to the inner wall of the carrier plate 13; the inside of the carrier plate 13 is slidably connected to a rack 2 19, the rack 2 19 is meshed with the gear 1 18, and the outer wall of the rack 2 19 is fixedly connected to a rack 3 20; the inner wall of the carrier plate 13 is rotatably connected to a gear 2 21, and the gear 2 21 is meshed with the rack 3 20; the inner wall of the carrier plate 13 is slidably connected to a rack 14, and the rack 14 is meshed with the gear 2 21; the outer wall of the gear 2 21 and the outer wall of the rack 14 are both fixedly connected to a baffle 15, and the outer wall of the baffle 15 is slidably connected to the outer wall of the carrier plate 13;

[0026] Specifically, first, place the navigation instrument on the carrier plate 13, which is a platform specially designed for navigation instruments and can ensure that the instrument is placed stably. Then, rotate the worm 16 on one side of the carrier plate 13. This is a key step. The rotation of the worm 16 drives the worm wheel 17 inside the carrier plate 13 to rotate. The rotation of the worm wheel 17 is not isolated. It transmits power through the connected gear 18 and rack 2 19. This design cleverly converts rotational motion into linear motion, thereby driving rack 3 20 and the baffle 15 on rack 3 20 to slide on the carrier plate 13. This process fully reflects the principle of mechanical transmission, so that the baffle 15 can move stably on the carrier plate 13. In addition, the operation of rack 2 19 also drives rack 3 20 And the rotation of gear 21, this step further enhances the stability of the device, because the other end of gear 21 is connected to rack 14, and the rotation of gear 21 can drive rack 14 to slide, and finally, the baffle 15 on rack 14 also slides, so that the navigation instrument is clamped by the two baffles 15. During operation, the two baffles 15 are always tightly fitted, which effectively prevents the navigation instrument from falling off during use. In this way, this device not only ensures the stability of the navigation instrument, but also greatly improves the user's sense of security. In short, this device for stably clamping the navigation instrument makes full use of the principle of mechanical transmission and realizes stable clamping of the navigation instrument through a series of precision gears and linear transmission.

[0027] Working principle: when a navigation instrument support frame is needed, the navigation instrument is placed on the carrier plate 13, and the worm 16 on one side of the carrier plate 13 is rotated, and the worm 16 drives the worm wheel 17 inside the carrier plate 13 to rotate, and the rotating worm wheel 17 drives the gear 1 18 and the rack 2 19 to operate, thereby driving the rack 3 20 and the baffle 15 on the rack 3 20 to slide on the carrier plate 13, and then the running rack 2 19 drives the rack 3 20 and the gear 2 21 to rotate, and at the same time drives the rack 1 14 to slide through the gear 2 21, thereby driving the baffle 15 on the rack 1 14 to slide, so that the navigation instrument is clamped by the two baffles 15 , to prevent the instrument from falling off when in use, thereby achieving the effect of stably clamping the navigation instrument. When the angle of the instrument needs to be adjusted, the push cylinder 4 is pressed, and the toothed disc 2 10 inside the support block 2 is pushed to move by the push cylinder 4. At the same time, the position of the toothed disc 2 10 is limited by the limit rod 12 to prevent the toothed disc 2 10 from shifting during movement. Then the connecting block 5 is rotated, and the loading plate 13 is driven to move by the connecting block 5, thereby achieving the effect of adjusting the angle of the instrument. After the adjustment is completed, the push cylinder 4 is released, and the toothed disc 2 10 is pushed to be stuck on the toothed disc 1 9 by the limit rod 12, thereby fixing the positions of the support block 2 and the connecting block 5, thereby achieving the effect of fixing the connecting block 5 after adjusting the angle.
