[0031] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0032] like Figures 1 to 8 As shown in the figure, this embodiment provides a navigation and positioning device, which includes a device body 1 and a display screen 101 located on the surface of the device body 1. An L-shaped frame 2 is fixedly connected to one end of the device body 1, and a positioning shaft 3 is fixedly connected to the top of the L-shaped frame 2. A positioning ring 301 is fixedly connected to the surface of the positioning shaft 3. A protective cover 4 is rotatably connected inside the positioning shaft 3. The protective cover 4 is connected to the positioning shaft 3 through the positioning ring 301. A rubber ring 401 is installed on the inner side of the protective cover 4. At the same time, there is a reserved space between the inside of the protective cover 4 and the display screen 101, which can play a buffering role. With the use of the rubber ring 401, the protective cover 4 can be protected from being damaged by external pressure on the display screen 101. The positioning ring 301 of the protective cover 4 can limit the positioning shaft 3 and prevent the two from being disconnected.

[0033] Both ends of the positioning shaft 3 are fixedly connected to the cover body 10. The end of the cover body 10 away from the positioning shaft 3 is fixedly connected to the first gear 7. A compression spring 9 is installed inside the cover body 10. A second gear 8 is provided at one end of the compression spring 9. The second gear 8 is located between the compression spring 9 and the first gear 7. The second gear 8 and the first gear 7 mesh with each other. The two ends of the compression spring 9 abut against the cover body 10 and the second gear 8 respectively. The compression spring 9 can make the second gear 8 elastic so that it can be disconnected from the first gear 7. The second gear 8 is located inside the cover body 10 and is movably connected to it.

[0034] A push block 5 is provided at the end of the cover 10 away from the positioning shaft 3. A movable rod 6 is fixedly connected inside the second gear 8. Both ends of the movable rod 6 pass through the second gear 8. One end of the movable rod 6 extends to the outside of the cover 10 and is fixedly connected to the push block 5. The movable rod 6 also passes through the first gear 7 and is movably connected to it. The other end of the movable rod 6 extends into the interior of the positioning shaft 3 and is movably connected to it. This allows the push block 5 to easily drive the second gear 8 to disconnect from the first gear 7 in order to adjust the angle of the protective cover 4. At the same time, the diameter of the push block 5 is smaller than the internal diameter of the cover 10, which facilitates the driving of the push block 5.

[0035] A protruding ring 601 is fixedly connected to the surface of the moving rod 6. A groove 304 is provided inside the positioning shaft 3. The protruding ring 601 is located inside the groove 304 and is movably connected to it. The diameter of the protruding ring 601 is larger than that of the moving rod 6, which can limit the movement of the moving rod 6 and prevent the moving rod 6 from being disconnected from the positioning shaft 3. At the same time, it can facilitate the movement of the moving rod 6 inside the positioning shaft 3. The length of the groove 304 is longer than that of a single set of protruding rings 601, which can facilitate the movement of the protruding rings 601.

[0036] A fixing block 12 is fixedly connected to the surface of the convex ring 601. A first sliding groove 302 is opened inside the positioning shaft 3. A stop block 303 is provided on one side of the first sliding groove 302. The fixing block 12 is located inside the first sliding groove 302 and is movably connected to it. The fixing block 12 extends to the top of the positioning shaft 3 through the first sliding groove 302, which can facilitate the movement of the fixing block 12 with the movement rod 6 and avoid interference between the two. The stop block 303 can limit the fixing block 12 and facilitate the rotation of the movement rod 6, which helps to open and close the protective cover 4.

[0037] A connecting rod 11 is fixedly connected to the top of the fixed block 12, and a slider 13 is fixedly connected to the other end of the connecting rod 11. Slide strips 1301 are fixedly connected to both sides of the slider 13. The connecting rod 11 can easily transmit the driving force of the moving rod 6 to the protective cover 4, so as to facilitate the opening and closing of the protective cover 4.

[0038] A second slide groove 402 is provided on one side of the protective cover 4. The slider 13 is located inside the second slide groove 402 and is movably connected to it. A guide groove adapted to the slider 1301 is provided inside the second slide groove 402, which can make its movement more stable and make the connection between the slider 13 and the protective cover 4 more stable.

[0039] The protective cover 4 has a reserved space between its interior and the display screen 101, which can act as a buffer. With the use of the rubber ring 401, the protective cover 4 can be protected from external pressure and prevent damage to the display screen 101. At the same time, the protective cover 4 can prevent the squeezing and impact forces from directly contacting the display screen 101, thereby reducing the damage to the display screen 101 caused by collisions and squeezing.

[0040] When using the equipment, first press the two sets of push blocks 5 to push the moving rod 6 towards the inside of the positioning shaft 3. During this process, the second gear 8 will move towards the compression spring 9 as the moving rod 6 moves, compressing and deforming it. At this time, the second gear 8 and the first gear 7 are disengaged. At the same time, when the moving rod 6 moves, it will also cause the convex ring 601 to move along the inside of the groove 304, and drive the connecting rod 11 through the fixing block 12 to make the slider 13 move along the inside of the second slide groove 402.

[0041] Then, rotate the push block 5 to drive the moving rod 6 to rotate. During this process, the moving rod 6 will drive the connecting rod 11 and the slider 13 through the fixed block 12, so that the protective cover 4 will rotate with the rotation of the moving rod 6. When it rotates to the appropriate area, the pressure on the two sets of push blocks 5 can be released. At this time, the protective cover 4 can also provide a sunshade for the display screen 101, preventing direct light from reducing the brightness of the display screen 101 and the damage to the eyes caused by light reflection.

[0042] After the pressure of the push block 5 is released, the compression spring 9 will restore its deformation and push the second gear 8 to move towards the first gear 7 until the two mesh. This achieves the purpose of self-locking. Furthermore, the self-locking method can prevent the protective cover 4 from being disconnected from the display screen 101 due to gravity when the display screen 101 is facing the ground, thus providing better protection for the display screen 101.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
