[0003] Navigation and positioning devices are frequently installed in automobiles. Existing navigation and positioning devices have poor buffering effects, and automobiles often travel on bumpy roads for extended periods, which can easily damage the navigation and positioning devices due to vibration, shortening their lifespan. Therefore, in order to ensure the high accuracy of navigation and positioning devices, we have launched a high-precision navigation and positioning device. Utility Model Content

The lower end of the movable rod extends outside the movable sleeve and is fixedly connected to the upper end of the sphere. A first buffer mechanism is provided between the movable rod and the movable sleeve. A support plate is fixedly mounted outside the movable rod. A second buffer mechanism is provided between the support plate and the base.
[0007] As a further embodiment of this utility model, the first buffer mechanism includes a positioning rod, the wall of the movable rod is provided with a strip-shaped hole, the positioning rod is slidably disposed in the strip-shaped hole, both ends of the positioning rod are fixedly connected to the inner side wall of the movable sleeve, and both the upper and lower ends of the positioning rod are fixedly provided with a first spring.
[0008] As a further embodiment of this utility model, the second buffer mechanism includes a second spring, and a plurality of the second springs are evenly arranged between the support plate and the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This high-precision navigation and positioning device, comprising a movable sleeve, base, support plate, navigation device body, sphere, movable rod, reinforcing rib, positioning rod, first spring, limiting ring, and second spring, works as follows: When the device is subjected to vertical vibration, the navigation device body drives the movable sleeve to slide upward or downward. The movable sleeve, through the positioning rod, compresses the corresponding first spring. The first spring extends or shortens, converting the vertical vibration into elastic potential energy, thus providing buffering against the vertical vibration experienced by the navigation device body. When the device is subjected to horizontal vibration, the navigation device body, through the movable sleeve and movable rod, drives the sphere to rotate within a spherical groove. Simultaneously, the movable rod, through the support plate, compresses the second spring. The second spring extends or shortens, converting the horizontal vibration into elastic potential energy, thus providing buffering against the horizontal vibration experienced by the navigation device body. This design provides buffering for the navigation device body in both vertical and horizontal directions, resulting in good buffering effect. This reduces the probability of damage and accuracy reduction under prolonged vibration, ensuring the high precision of the navigation and positioning device. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4 This utility model provides a technical solution:
[0021] A high-precision navigation and positioning device includes a navigation device body 4 and a base 2. The base 2 has mounting holes at the four corners of its upper end and a spherical groove in the middle of its upper end. A ball 5 is rotatably mounted in the spherical groove. A movable sleeve 1 is fixedly mounted at the bottom of the navigation device body 4. A movable rod 6 is slidably mounted in the movable sleeve 1. The lower end of the movable rod 6 extends to the outside of the movable sleeve 1 and is fixedly connected to the upper end of the ball 5.
[0022] refer to Figure 2 and Figure 3 A first buffer mechanism is provided between the movable rod 6 and the movable sleeve 1. The first buffer mechanism includes a positioning rod 8. The wall of the movable rod 6 is provided with a strip hole. The positioning rod 8 is slidably disposed in the strip hole. Both ends of the positioning rod 8 are fixedly connected to the inner side wall of the movable sleeve 1. The upper and lower ends of the positioning rod 8 are fixedly provided with a first spring 9. The first spring 9 is always in a compressed state.
[0023] refer to Figure 2 and Figure 4 A support plate 3 is fixedly provided on the outside of the movable rod 6. A second buffer mechanism is provided between the support plate 3 and the base 2. The second buffer mechanism includes a second spring 11. Multiple second springs 11 are evenly arranged between the support plate 3 and the base 2. A limiting ring 10 is fixedly provided on the opposite side of the support plate 3 and the base 2 at the position corresponding to the second spring 11. The two ends of the second spring 11 are respectively engaged with the corresponding limiting ring 10. The second spring 11 is always in a compressed state. The inner diameter of the limiting ring 10 is larger than the diameter of the second spring 11.
[0024] refer to Figure 3 Multiple reinforcing ribs 7 are integrally formed between the movable sleeve 1 and the bottom of the navigation device body 4. The reinforcing ribs 7 can greatly improve the structural strength of the movable sleeve 1 and the navigation device body 4.
[0025] In use, when the device is subjected to vertical vibration, the navigation device body 4 drives the movable sleeve 1 to slide upward or downward. The movable sleeve 1 compresses the corresponding first spring 9 through the positioning rod 8. The first spring 9 extends or shortens, converting the vertical vibration into elastic potential energy, thereby providing buffering for the vertical vibration received by the navigation device body 4. When the device is subjected to horizontal vibration, the navigation device body 4 drives the ball 5 to rotate in the spherical groove through the movable sleeve 1 and the movable rod 6. At the same time, the movable rod 6 compresses the second spring 11 through the support plate 3. The second spring 11 extends or shortens, converting the horizontal vibration into elastic potential energy, thereby providing buffering for the horizontal vibration received by the navigation device body 4. It can provide buffering for the navigation device body 4 in both vertical and horizontal directions. The buffering effect is good, reducing the probability of damage and accuracy reduction of the navigation and positioning device under long-term bumps, and ensuring the high accuracy of the navigation and positioning device.
