[0018] Example:

[0019] Figure 1 The present invention shows a liftable connection mechanism for vehicle navigation, including a sliding block 1, a fixing unit 2, a positioning block 3 and a pressing plate 4. The fixing unit 2 includes a first fixing plate 21, a second fixing plate 22 and a third fixing plate 23. The second fixing plate 22 is fixed to the right end of the first fixing plate 21, and the third fixing plate 23 is fixed to the second fixing plate 22. The second fixing plate 22 is provided with a first groove 221. The positioning block 3 can be slidably connected to the second fixing plate 22 by moving left and right. The pressing plate 4 can be slidably connected to the first groove 221 vertically or forward and backward. The pressing plate 4 is located at the right end of the first fixing plate 21. The right end of the positioning block 3 is provided with an elastic component 31. The sum of the heights of the clamping sheet 4 and the positioning block 3 is the same as the depth of the first groove 221; the sliding block 1 is slidably connected to the first fixing sheet 21, the first fixing sheet 21 is provided with a first through groove 211, the sliding block 1 is located at the right end of the first through groove 211 or inside the first through groove 211, one end of the sliding block 1 is provided with a plurality of tooth grooves 11, the left end of the positioning block 3 is provided with a plurality of convex teeth 31, the second fixing sheet 22 is provided with a first through hole 223 for the convex teeth 31 to pass through, the convex teeth 31 pass through the first through hole 223 and extend to the left end of the second fixing sheet 22, the number of tooth grooves 11 is greater than the number of convex teeth 31, and the sliding block 1 can be slidably connected to the first fixing sheet 21 so as to move up and down.

[0020] The sliding block 1 is located at the right end of the first through slot 211, and the left end of the sliding block 1 is provided with a first boss 12, the first boss 12 penetrates the first through slot 211, and the length of the first through slot 211 is greater than the length of the first boss 12, the first boss 12 and the first through slot 211 are slidably connected so as to be movable up and down, and the sliding block 1 is located in the gap between the first fixing plate 21 and the second fixing plate 22. The first boss 12 extends to the outside of the first fixing plate 21, and can be hingedly connected to the vehicle-mounted navigation host by threaded connection by setting a threaded hole on the first boss 12. Since the first boss 12 has a length, a gap exists between the first fixing plate and the vehicle-mounted navigation host, and the first fixing plate and the vehicle-mounted navigation host can be relatively rotated, thereby adjusting the angle of the vehicle-mounted navigation display terminal.

[0021] The front end of the compression sheet 4 is provided with a connecting sheet 41, the left end of the connecting sheet 41 is provided with a second boss 411, the first fixing sheet 21 is provided with a second through slot 212, and the second boss 411 is slidably matched with the second through slot 212. The second boss 411 and the second through slot 212 are arranged, and the second through slot 212 limits the front and rear sides of the second boss 411, which can prevent the compression sheet 4 from deviating during the up and down movement. At the same time, the second boss 411 extends out of the left side of the first fixing sheet 21, and the user can adjust the vertical position of the compression sheet 4 by moving the second boss 411 up and down, thereby improving the user's experience.

[0022] The first groove 221 is an "L"-shaped structure including a vertical end 2211 and a horizontal end 2212. The lower end of the vertical end 2211 is connected to the left end of the horizontal end 2212. The positioning block 3 is located in the horizontal end 2212. The side wall of the horizontal end 2212 limits the vertical movement of the positioning block 3. The clamping plate 4 can move up and down along the vertical end 2211. The front end of the L-shaped structure is provided with a third through groove for the connecting plate 41 to pass through. The upper surface and the lower surface of the horizontal end 2212 respectively fix the upper and lower positions of the positioning block 3. The connection between the horizontal end 2212 and the vertical end 2211 can be used for the clamping plate 4 to clamp the positioning block 3. The vertical end 2211 can be used for the clamping plate 4 to move up and down. The structure of the first groove 221 can limit the upper and lower and right ends of the positioning block 3 without affecting the upper and lower movement of the clamping plate 4 which can be on the same horizontal plane as the positioning block 3.

[0023] The elastic component 31 is a spring, a positioning pin 32 is provided on one side of the positioning block 3, the spring is sleeved on the outside of the positioning pin 32, the length of the positioning pin 32 is less than the depth of the first groove 221, and the length of the spring is greater than the depth of the first groove 221. The structure is simple, the spring has high elasticity, and the convex teeth 31 of the positioning block 3 are more likely to always contact the tooth groove 11. The positioning pin 32 can guide and support the spring to prevent the spring from falling.

[0024] Working principle: The first fixing piece 21 is used to fix the rear cover of the vehicle navigation display terminal, and the left end of the sliding block 1 is used to fix the vehicle navigation host. When the user needs to adjust the vehicle display terminal, the user pulls up the first pressing piece 4, such as Figure 3 As shown, the pressing sheet 4 and the positioning block 3 are not on the same horizontal plane. At this time, the positioning block 3 is tightly attached to the bottom of the first groove 221 under the support of the elastic component 31, and the back cover of the vehicle-mounted navigation display terminal is pulled up and down. The first fixing sheet 21 drives the second fixing sheet 22 to move up and down, and the second fixing sheet 22 drives the positioning block 3 to move up and down relative to the sliding block 1. The convex teeth 31 contact and squeeze the tooth grooves 11 at different vertical positions in turn. At this time, the positioning block 3 will move left and right during the squeezing process of the convex teeth 31 and different tooth grooves 11. It is the elastic deformation of the elastic component 31 that allows the positioning block 3 to move left and right. Therefore, the positioning block 3 can slide at different positions of the uneven tooth grooves 11, thereby completing the relative movement of the second fixed plate and the sliding block 1. When it moves to the desired position, the user pulls down the second boss 411. At this time, Figure 2 As shown, the clamping plate 4 and the positioning block 3 are located in the same horizontal plane. Since the sum of the widths of the clamping plate 4 and the positioning block 3 made of rigid material is equal to the gap between the third fixing plate 23 and the second fixing plate 22, the left and right positions of the positioning block 3 are respectively fixed by the second fixing plate 22 and the clamping plate 4, and the left and right movement of the positioning block 3 is restricted. At this time, the convex tooth 31 cannot move left and right, so the convex tooth 31 is clamped in a single tooth groove 11 and cannot move to other tooth grooves 11. At this time, the relative position of the sliding block 1 and the second fixing plate 22 is fixed, and the vehicle-mounted display terminal is positioned after the height adjustment is completed.
