Description

Technical Field

[0001] This invention relates to the field of GPS positioning device technology, specifically a latch-type mobile terminal GPS positioning device. Background Technology

[0002] A latching GPS positioning device is a GPS positioning module designed for use in mobile terminal devices. Its feature is that it can be quickly installed and removed through a latching mechanism. This design makes the positioning device easy to integrate into the mobile terminal and can be quickly deployed or replaced when needed. With the advancement of technology, modern cars are increasingly integrating advanced information technology and communication functions, making cars, to some extent, a special kind of mobile terminal.

[0003] Chinese Patent Publication No. CN219728055U discloses an easy-to-install vehicle GPS positioning device, including a positioning device body. Several heat dissipation holes are provided on both sides of the positioning device body. A base plate is installed below the positioning device body. Several shock-absorbing round blocks are fixedly connected to the upper surface of the base plate. The upper ends of the shock-absorbing round blocks are fixedly connected to the positioning device body. Fixed shafts are fixedly connected to both sides of the base plate. A rotating rod passes through the interior of the fixed shaft. Clamping components are fixedly connected to both ends of the rotating rod. The upper ends of the clamping components are curved. The shock-absorbing round blocks are hollow and are made of rubber. A torsion spring is fitted onto the arc surface of the rotating rod. The two ends of the torsion spring are fixedly connected to the clamping components and the fixed shafts, respectively.

[0004] In existing technology, GPS positioning devices eliminate vibrations and shaking generated during vehicle operation by installing shock-absorbing balls at the bottom, thus preventing inaccurate positioning caused by vibrations. However, the shock-absorbing balls will be damaged after prolonged use or need to be replaced after a certain period of use. The shock-absorbing balls are generally made of rubber, and the diameter of the end of the shock-absorbing ball is larger than the diameter of the mounting hole. When replacing the shock-absorbing balls, they must be installed by pulling or other means, which is a cumbersome and laborious operation.

[0029] Please see Figures 1-10In this embodiment of the invention, a latching mobile terminal GPS positioning device includes a positioning device body 1 and a first base plate 5. Side plates 2 are rotatably connected to both sides of the first base plate 5. A second base plate 7 for mounting the positioning device body 1 is disposed between the two sets of side plates 2. The positioning device body 1 is mounted on the top of the second base plate 7. A shock-absorbing ball 8 is disposed between the second base plate 7 and the first base plate 5. A fixing plate 62 is symmetrically fixed to the bottom of the second base plate 7 along its center. A movable plate 63 is disposed on the side of the fixing plate 62 near the center of the second base plate 7. The movable plate 63 is slidably connected to the bottom of the second base plate 7. The bottom center of the second base plate 7 is rotatably connected to a synchronous gear 68. The two sides of the synchronous gear 68 are meshed with first toothed plates 67. The ends of the two sets of first toothed plates 67 that are relatively far apart are respectively fixedly connected to the corresponding movable plates 63. The fixed plate 62 and the movable plate 63 are provided with upper mounting grooves for installing and fixing the top of the shock-absorbing ball 8 at opposite ends. The fixed plate 62 is provided with a locking assembly on the side away from the second base plate 7. The top of the first base plate 5 is provided with a lower mounting assembly for fixing the bottom of the shock-absorbing ball 8.

[0030] Preferably, baffles are provided at the bottom of the first base plate 5 and on both sides near the side plate 2. The baffles are not shown in the figure. The baffles can limit the rotation and unfolding angle of the side plate 2, so that the side plate 2 can be rotated and unfolded to the maximum state of being flush with the first base plate 5. The side plate 2 is provided with a retaining plate structure protruding outward from the first base plate 5 at the end away from the first base plate 5. The upper mounting grooves on the fixed plate 62 and the movable plate 63 are both semi-circular structures. When the fixed plate 62 and the movable plate 63 are fitted, the upper mounting grooves on the two form a retaining groove 64, and the retaining groove 64 is fitted with the top of the shock-absorbing ball 8.

[0031] Please see Figures 1-3 Preferably, the locking assembly includes a locking block 65; both ends of the locking block 65 are elastically connected to the fixed plate 62, a slider is provided on the side end of the locking block 65 near the fixed plate 62, a slide groove adapted to the slider is provided on the side wall of the fixed plate 62, and a spring is provided between the slider and the slide groove, a buckle 66 is slidably engaged on one side of the locking block 65, the end of the buckle 66 away from the locking block 65 is fixedly connected to the movable plate 63, and an inclined surface is provided on the end of the buckle 66 away from the movable plate 63.

[0032] In practical use, in the initial state, the movable plate 63 is away from the fixed plate 62, the buckle 66 and the locking block 65 are separated, and the locking block 65 is in a state corresponding to the end of the buckle 66 under the action of the corresponding spring. When it is necessary to install the shock-absorbing ball 8, firstly, the top end of the shock-absorbing ball 8 is inserted into the upper mounting groove on the fixed plate 62, and then the movable plate 63 is slid towards the fixed plate 62. The movement of one set of movable plates 63 drives the corresponding first toothed plate 67 to move, and then, through the action of the synchronous gear 68, the other set of first toothed plates 67 moves synchronously towards the corresponding fixed plate 62. Then, push another set of movable plates 63 to move towards another set of fixed plates 62, thereby adapting the corresponding set of movable plates 63 and fixed plates 62, thus fixing and limiting the shock absorber ball 8 at the bottom of the second base plate 7. Then, place the bottom of the shock absorber ball 8 in the lower mounting assembly, and then rotate the side plate 2 upward so that the side plate 2 is perpendicular to the first base plate 5. The rotation of the side plate 2 will drive the lower mounting assembly to fix and limit the bottom end of the shock absorber ball 8, thereby completing the installation operation of the shock absorber ball 8 and the positioning device body 1. The operation is simple and practical. Finally, place the whole thing in the vehicle armrest box.

[0033] Please see Figures 1-2 , Figures 4-6Preferably, the lower mounting assembly includes an active plate 6 and a driven plate 61. The active plate 6 is slidably disposed on the top of the first base plate 5 and slidably engaged with the side plate 2. The driven plate 61 is slidably disposed on the side of the active plate 6 away from the side plate 2 and slidably connected to the top of the first base plate 5. The active plate 6 and the driven plate 61 are symmetrically arranged along the center of the first base plate 5. The active plate 6 and the driven plate 61 have lower mounting grooves on opposite sides that correspond to and are identical to the fixed plate 62 and the movable plate 63. A second toothed plate 15 is fixedly disposed at the bottom center of both the active plate 6 and the driven plate 61. A rotating shaft 14 is driven between the two sets of second toothed plates 15. The bottom of the rotating shaft 14 is rotatably connected to the first base plate 5. The teeth of the two sets of second toothed plates 15 are arranged opposite each other. The rotating shaft 14 is disposed at the center position when the active plate 6 and the driven plate 61 are fitted together. A spring is disposed between one set of second toothed plates 15 and the inner wall of the first base plate 5. Thus, in the initial state during use, the side plate 2 is relatively... With the first base plate 5 in the unfolded state, the active plate 6 and the driven plate 61 are relatively far apart. The rotating shaft 14 is located between the opposite ends of the two sets of second toothed plates 15. The end of the active plate 6 near the side plate 2 protrudes from the side of the first base plate 5 near the side plate 2. When it is necessary to fix and limit the bottom end of the shock-absorbing ball 8, the bottom end of the shock-absorbing ball 8 is placed in the lower mounting groove corresponding to the active plate 6 and the driven plate 61. Then, the side plate 2 is rotated upward to a state perpendicular to the first base plate 5. During this process, the side wall of the side plate 2 will fit with the side wall of the active plate 6. Then, the active plate 6 is pushed to move towards the driven plate 61. The movement of the active plate 6 drives the corresponding second toothed plate 15 to move. The movement of the second toothed plate 15 drives the rotating shaft 14 to move clockwise, thereby causing the other set of second toothed plates 15 to move, allowing the driven plate 61 to move towards the active plate 6 and fit with the active plate 6. When the active plate 6 and the driven plate 61 fit together, the work of fixing the bottom end of the shock-absorbing ball 8 is completed.

[0034] Please refer to 6- Figure 7Preferably, in order to allow the side plate 2 to rotate at a certain angle after rotating to be perpendicular to the first base plate 5, thereby better adapting to the size of the armrest box, a limiting hole 19 is provided on the outer side wall of the bottom end of the rotating shaft 14. Multiple sets of limiting holes 19 are arranged in a circular array along the center of the rotating shaft 14. A wedge block 18 that slides and adapts to the limiting hole 19 is provided on the side of the rotating shaft 14 near the driven plate 61. A driving block 9 is elastically connected to the side wall of the first base plate 5 near the side plate 2 by a spring. An extension plate 13 is fixedly provided at the end of the driving block 9 away from the side plate 2. The wedge block 18 is elastically connected to the extension plate 13 away from the side plate 2 by a spring. One end of the drive block 9; the drive block 9 is positioned corresponding to the rotating shaft 14, and the drive block 9 can slide out of the side wall of the first base plate 5. The top of the drive block 9 is provided with an inclined surface facing the unfolded state of the side plate 2. The extension plate 13 is a concave structure and is sleeved on the periphery of the rotating shaft 14. The top of the rotating shaft 14 is a gear structure that meshes with the second toothed plate 15. The end of the wedge block 18 away from the extension plate 13 is provided with an inclined surface. By setting the inclined surface, when the side plate 2 rotates and pushes the active plate 6 upward to move towards the driven plate 61, the wedge block 18 will not affect the clockwise rotation of the rotating shaft 14 even if it is adapted to the limiting hole 19.

[0035] In practical use, when the side plate 2 is in the unfolded state relative to the first base plate 5, the end of the side plate 2 cooperates with the drive block 9, causing the drive block 9 to retract into the side wall of the first base plate 5. This causes the end of the extension plate 13 away from the drive block 9 to move away from the rotating shaft 14, separating the wedge block 18 from the limiting hole 19, while the spring corresponding to the drive block 9 is in a compressed state. When the side plate 2 rotates upward to be perpendicular to the top of the first base plate 5, the end of the side plate 2 separates from the drive block 9. Subsequently, the drive block 9 moves and protrudes from the side wall of the first base plate 5 under the action of the corresponding spring. The movement of the drive block 9 drives the extension plate 13 to move, thereby making the wedge block 18 fit with the limiting hole 19. Then, when the active plate 6 moves towards the driven plate 61, the second toothed plate 15 drives the rotating shaft 14 to rotate clockwise. At this time, the wedge block 18 will not obstruct the rotation. The rotation of the shaft 14 causes the driven plate 61 and the active plate 6 to move and adapt, thereby limiting and fixing the bottom of the shock-absorbing ball 8. Then, when the whole is placed in the armrest box, since the vertical side plate 2 may be smaller than the size of the armrest box, the side plate 2 needs to rotate a certain angle towards the outer edge of the first base plate 5 to adapt to its size. When the side plate 2 rotates outward and is no longer perpendicular to the first base plate 5, that is, the active plate 6 has the condition to move towards the side plate 2. However, at this time, the wedge block 18 is in the limiting hole 19 and will prevent the shaft 14 from rotating counterclockwise, thereby limiting the position of the second toothed plate 15. This avoids the active plate 6 and the driven plate 61 moving relatively far apart, which would cause the shock-absorbing ball 8 to become unstable and thus easily cause the positioning device body 1 to fall off the first base plate 5 and collide, resulting in damage.

[0036] Please see Figures 1-2 , Figures 8-10 Preferably, the side plate 2 is elastically connected to the center of one side of the positioning device body 1 by a spring via an auxiliary plate 3. The auxiliary plate 3 is positioned above the positioning device body 1. In use, after the positioning device body 1 is installed in the armrest box via the side plate 2 and the first bottom plate 5, the auxiliary plate 3 allows a partition to be placed on it to shield the positioning device body 1. This facilitates the placement of items and effectively prevents external debris from falling onto the positioning device body 1 and causing damage. The auxiliary plate 3 also facilitates the removal of the positioning device body 1 from the armrest box. The bottom of the auxiliary plate 3 is equipped with an auxiliary component.

[0037] Please see Figures 5-10 Preferably, the auxiliary components include a threaded sleeve 12; a piston rod 16 is slidably connected inside the threaded sleeve 12, a spring is provided between the piston rod 16 and the threaded sleeve 12, a suction cup 11 is fixedly installed at the end of the threaded sleeve 12 away from the positioning device body 1, a square plate is fixedly installed at the end of the piston rod 16 away from the threaded sleeve 12, a round rod is slidably arranged between the square plate and the side wall of the side plate 2, a trigger plate 4 is fixedly installed at the bottom of the auxiliary plate 3, the bottom of the trigger plate 4 is slidably engaged with the square plate, the suction cup 11 is located on the side of the side plate 2 away from the positioning device body 1, the threaded sleeve 12 and the piston rod 16 can only slide in the horizontal direction, and the piston rod 16 is limited by the cooperation of the round rod and the square plate, the bottom of the trigger plate 4 is provided with an inclined surface facing the square plate, and the end of the suction cup 11 is provided with a through hole communicating with the inside of the threaded sleeve 12.

[0038] In this way, when the positioning device body 1, the first base plate 5, and the side plate 2 are placed in the armrest box, the threaded sleeve 12 moves away from the positioning device body 1, so that the suction cup 11 adheres to the inner wall of the armrest box, thereby fixing the side plate 2. This prevents the side plate 2 from sliding in the armrest box when the vehicle brakes or turns sharply, thus keeping the positioning device body 1 stable on the first base plate 5.

[0039] Furthermore, preferably, a mating ring 20 is rotatably connected to the periphery of the threaded sleeve 12. The mating ring 20 is rotatably disposed at the center of the side wall of the side plate 2. A toothed ring is fixedly disposed on the periphery of the mating ring 20. The threaded sleeve 12 and the mating ring 20 are threadedly connected. When the mating ring 20 rotates, the threaded sleeve 12 can move horizontally within the mating ring 20.

[0040] Furthermore, preferably, a lifting plate 10 is slidably connected to the side of the side plate 2 away from the positioning device body 1. An elastic telescopic column 23 is fixedly connected to the bottom of one end of the lifting plate 10 inside the side wall of the side plate 2. A third toothed plate 22 is provided at the bottom of the elastic telescopic column 23. The third toothed plate 22 is located on one side of the toothed ring and is in transmission cooperation with the toothed ring. A limiting plate 21 is elastically connected to the side wall of the side plate 2 by a spring. The bottom end of the limiting plate 21 is slidably engaged with the top end of the third toothed plate 22. The top end of the limiting plate 21 is slidably engaged with the lifting plate 10. A storage groove for storing the lifting plate 10 is provided at the top of the side plate 2. A guide groove for sliding the lifting plate 10 is provided on the side wall of the side plate 2. A slope facing the lifting plate 10 is provided at the bottom end of the limiting plate 21. A slope facing the third toothed plate 22 is provided at the top end of the limiting plate 21. The top end of the limiting plate 21 slides into the top end of the guide groove.

[0041] In practical use, when the shock-absorbing ball 8 is installed via the fixed plate 62, movable plate 63, and lower mounting assembly, the side plate 2 is perpendicular to the first base plate 5. The end of the threaded sleeve 12 away from the positioning device body 1 is close to the side of the side plate 2 away from the positioning device body 1, and the piston column 16 is fully retracted within the threaded sleeve 12. The bottom of the trigger plate 4 slides and adapts to the square plate. The spring between the threaded sleeve 12 and the piston column 16 is in normal condition. The lifting plate 10 is positioned close to the threaded sleeve 12. The bottom end of the limiting abutment plate 21 is in contact with the top of the third toothed plate 22, and the top end of the limiting abutment plate 21 extends into the guide groove. The top of the third toothed plate 22 corresponds to one side of the mating ring 20, and the two mesh. When the side plate 2 and the first bottom plate 5 are placed in the armrest box, the lifting plate 10 contacts and adheres to both sides of the top of the armrest box. As the side plate 2 moves downward, the lifting plate 10 moves upward in the guide groove. The movement of the lifting plate 10 causes the elastic telescopic column 23 to elastically extend. At this time, because the third toothed plate 22 is limited by the limiting plate 21, the third toothed plate 22 cannot move. When the side plate 2 and the first bottom plate 5 are completely placed in the armrest box, the lifting plate 10 also moves synchronously to the top position of the guide groove. At the same time, the lifting plate 10 acts on the limiting plate 21 to move away from the guide groove. The movement towards the groove causes the bottom end of the limiting plate 21 to separate from the top of the third toothed plate 22. Subsequently, the third toothed plate 22 moves upward under the action of the elastic telescopic column 23, causing the toothed ring to rotate. This rotation drives the mating ring 20 to rotate, which in turn causes the threaded sleeve 12 to move away from the positioning device body 1. This causes the suction cup 11 to adhere to the inner wall of the armrest box, thus limiting and fixing the side plate 2 and preventing it from easily moving and affecting the normal use of the positioning device body 1. When the threaded sleeve 12 moves away from the positioning device body 1, the piston column 16... Under the constraint, it is in a fixed state, which causes the spring between the threaded sleeve 12 and the piston column 16 to stretch. When it is necessary to remove the positioning device body 1 and the side plate 2 from the armrest box, the auxiliary plate 3 is pulled upward. The auxiliary plate 3 drives the trigger plate 4 to move upward and separate from the square plate. Then, under the action of the spring between the piston column 16 and the threaded sleeve 12, the piston column 16 moves towards the suction cup 11. During this process, the piston column 16 compresses the gas between the threaded sleeve 12 and the suction cup 11, thereby allowing the suction cup 11 to release the negative pressure adsorption state on the inner wall of the armrest box. Then, the side plate 2, the positioning device body 1, and the first bottom plate 5 can be removed as a whole, which is simple and convenient.

[0042] Please see Figure 9Preferably, a pressure relief component 17 is fixedly connected to the center of the piston rod 16 near the suction cup 11. The pressure relief component 17 includes a positioning rod and a shovel plate. The end of the positioning rod away from the suction cup 11 is fixedly connected to the piston rod 16, and the end of the shovel plate near the piston rod 16 is rotatably connected to the positioning rod. A torsion spring is provided at the rotatable connection between the shovel plate and the positioning rod. In the initial state, the shovel plate and the positioning rod remain horizontal relative to each other under the action of the torsion spring. The end of the shovel plate away from the positioning rod is provided with an upward arc segment. Thus, in use... When the piston rod 16 moves toward the suction cup 11, it pushes the positioning rod to move, which in turn causes the shovel to move toward the inner wall of the armrest box. Then, when the arc-shaped section at the end of the shovel contacts the inner wall of the armrest box, as the piston rod 16 continues to move and the arc-shaped plate and the shovel can rotate relative to the positioning rod, the shovel will rotate upward relative to the positioning rod, thereby scooping up the upper end of the suction cup 11. This avoids the problem that the suction cup 11 may come into contact with the armrest box again when the side plate 2 is lifted out of the armrest box later.
