First tooth plates 67 are meshed on both sides of the synchronous gear 68. The relatively far ends of the two groups of first tooth plates 67 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 the top of the fixed damping ball 8 at opposite ends. A locking assembly is provided on the side of the fixed plate 62 away from the second bottom plate 7, and a lower mounting assembly for fixing the bottom end of the damping ball 8 is provided on the top of the first bottom plate 5.

[0029] Preferably, baffles are provided at the bottom of the first bottom plate 5 and on both sides close to the side plates 2. The baffles are not shown in the figure. The baffles can limit the rotation and expansion angle of the side plates 2, so that the maximum rotation and expansion state of the side plates 2 on the first bottom plate 5 is flush with the first bottom plate 5, and the end of the side plate 2 away from the first bottom plate 5 is provided with a card plate structure protruding toward the periphery of the first bottom plate 5, and the upper mounting grooves on the fixed plate 62 and the movable plate 63 are both semicircular structures. When the fixed plate 62 and the movable plate 63 are adapted, the upper mounting grooves on the two form a card slot 64, and the card slot 64 is adapted to the top of the shock-absorbing ball 8.

[0030] See also Figure 1-Figure 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 at one end of the locking block 65 close to the fixed plate 62, a sliding 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 sliding groove, a buckle 66 is slidably fitted on one side of the locking block 65, an 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 at the end of the buckle 66 away from the movable plate 63.

[0031] When in 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 the shock-absorbing ball 8 needs to be installed, the top end of the shock-absorbing ball 8 is first inserted into the upper mounting groove on the fixed plate 62, and then the movable plate 63 is slid toward the fixed plate 62. The movement of one group of movable plates 63 drives the corresponding first toothed plates 67 to move, and then the action of the synchronous gear 68 makes the other group of first toothed plates 67 move synchronously toward the corresponding fixed plate 62. Then push another set of movable plates 63 to move toward another set of fixed plates 62, so that the corresponding set of movable plates 63 and fixed plates 62 are adapted, thereby fixing the shock-absorbing ball 8 at the bottom of the second bottom plate 7, and then place the bottom of the shock-absorbing ball 8 in the lower mounting assembly accordingly, and then rotate the side plate 2 upward so that the side plate 2 is perpendicular to the first bottom plate 5. The rotation of the side plate 2 will drive the lower mounting assembly to fix the bottom end of the shock-absorbing ball 8, thereby completing the installation operation of the shock-absorbing ball 8 and the positioning device body 1. The operation is simple and practical, and finally the whole can be placed in the vehicle armrest box.

[0032] See also Figure 1-Figure 2 , Figure 4-Figure 6The movable plate 63 is provided with a lower mounting groove which is the same as and corresponds to the fixed plate 62 and the movable plate 63. The lower center of the active plate 6 and the driven plate 61 is fixed with a second tooth plate 15, and the two sets of second tooth plates 15 are matched with a rotating shaft 14 for transmission, and the bottom of the rotating shaft 14 is rotatably connected with the first bottom plate 5; the teeth on the two sets of second tooth plates 15 are arranged opposite to each other, and the rotating shaft 14 is arranged at the center position when the active plate 6 and the driven plate 61 are adapted, and a spring is arranged between one set of the second tooth plates 15 and the inner wall of the first bottom plate 5, so that when in use, in the initial state, the side plate 2 is relatively When the first bottom plate 5 is in the expanded state, the active plate 6 and the driven plate 61 are relatively far away from each other, and the rotating shaft 14 is between the opposite ends of the two sets of second tooth plates 15, and the end of the active plate 6 close to the side plate 2 protrudes out of the side of the first bottom plate 5 close to the side plate 2. When it is necessary to fix 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, and then the side plate 2 is rotated upward to a state perpendicular to the first bottom plate 5. In this process, the side wall of the side plate 2 will fit with the side wall of the active plate 6, and then the active plate 6 is pushed to move in the direction of the driven plate 61. The movement of the active plate 6 drives the corresponding second tooth plate 15 to move. The movement of the second tooth plate 15 drives the rotating shaft 14 to move clockwise, thereby making the other set of second tooth plates 15 move, so that the driven plate 61 moves toward the active plate 6 and fits with the active plate 6. When the active plate 6 and the driven plate 61 are adapted and fitted, the bottom end of the shock-absorbing ball 8 is installed and fixed.

[0033] Please refer to 6- Figure 7Preferably, in order to allow the side panel 2 to rotate at a certain angle after rotating to be perpendicular to the first bottom panel 5, so as to better adapt to the size of the armrest box, a limiting hole 19 is provided on the outer peripheral side wall of the bottom end of the rotating shaft 14, and a plurality of limiting holes 19 are provided in a circular array along the center of the rotating shaft 14. A wedge block 18 that is slidably adapted to the limiting hole 19 is provided on the side of the rotating shaft 14 close to the driven plate 61. A driving block 9 is elastically connected to the side wall of the first bottom panel 5 close to the side panel 2 through a spring. An extension plate 13 is fixedly provided on the end of the driving block 9 away from the side panel 2. The wedge block 18 is elastically connected to the extension plate 13 away from the extension plate 13 through a spring. One end of the driving block 9; the driving block 9 is arranged corresponding to the position of the rotating shaft 14, and the driving block 9 can slide out of the side wall of the first bottom plate 5, and the top of the driving block 9 is provided with an inclined surface facing the unfolded state of the side plate 2, the extension plate 13 is arranged as a "concave" structure, and the extension plate 13 is sleeved on the periphery of the rotating shaft 14, and the top of the rotating shaft 14 is a gear structure that is meshed with the second tooth plate 15, and the end of the wedge block 18 away from the extension plate 13 is provided with an inclined surface. Through the setting of the inclined surface, when the side plate 2 rotates to push the active plate 6 upward to move toward the driven plate 61, even if the wedge block 18 is adapted to the limiting hole 19, it will not affect the clockwise rotation of the rotating shaft 14.

[0034] During specific use, when the side plate 2 is in the expanded state relative to the first bottom plate 5, the end of the side plate 2 cooperates with the driving block 9 so that the driving block 9 is retracted in the side wall of the first bottom plate 5, thereby allowing one end of the extension plate 13 to move away from the driving block 9 and away from the rotating shaft 14, so that the wedge block 18 is separated from the limiting hole 19, and the spring corresponding to the driving block 9 is in a compressed state; when the side plate 2 is rotated upward to be perpendicular to the top of the first bottom plate 5, the end of the side plate 2 is separated from the driving block 9, and then the driving block 9 moves to protrude out of the side wall of the first bottom plate 5 under the action of the corresponding spring, and the movement of the driving block 9 drives the extension plate 13 to move, thereby making the wedge block 18 adapt to the limiting hole 19, and then when the active plate 6 moves toward the driven plate 61, the second tooth plate 15 drives the rotating shaft 14 to rotate clockwise. At this time, the wedge block 18 will not hinder The rotation of the rotating shaft 14 causes the driven plate 61 to move and adapt with the active plate 6, thereby limiting and fixing the bottom of the shock-absorbing ball 8. Subsequently, when the whole is placed in the armrest box, since the vertical side panel 2 may be smaller than the size of the armrest box, the side panel 2 needs to be rotated a certain angle toward the periphery of the first bottom plate 5 to adapt to its size. When the side panel 2 rotates toward the periphery and is no longer perpendicular to the first bottom plate 5, that is, the active plate 6 has the conditions to move toward the side panel 2, but at this time the wedge block 18 is in the limiting hole 19 and will prevent the rotating shaft 14 from rotating counterclockwise, thereby limiting the position of the second tooth plate 15, avoiding the active plate 6 and the driven plate 61 from moving away from each other, resulting in unstable fixation of the shock-absorbing ball 8, which in turn easily causes the positioning device body 1 to fall off the first bottom plate 5 and collide and cause damage.

[0035] See also Figure 1-Figure 2 , Figure 8-Figure 10 Preferably, the side panel 2 is elastically connected with an auxiliary panel 3 via a spring at the center of one side of the positioning device body 1, and the auxiliary panel 3 is arranged above the positioning device body 1. When in use, after the positioning device body 1 is installed in the armrest box through the side panel 2 and the first bottom plate 5, a partition can be placed on the auxiliary panel 3 through the setting of the auxiliary panel 3, so as to shield the positioning device body 1. On the one hand, it is convenient to place items, and on the other hand, it is effective to prevent external debris from falling on the positioning device body 1 and causing damage to the positioning device body 1. Subsequently, the positioning device body 1 is also conveniently taken out of the armrest box through the auxiliary panel 3, and the bottom transmission of the auxiliary panel 3 is matched with an auxiliary component.

[0036] See also Figure 5-Figure 10 Preferably, the auxiliary component includes a threaded sleeve 12; a piston column 16 is sealed and slidably connected in the threaded sleeve 12, a spring is arranged between the piston column 16 and the threaded sleeve 12, a suction cup 11 is fixedly installed on the end of the threaded sleeve 12 away from the positioning device body 1, a square plate is fixedly arranged on the end of the piston column 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 arranged at the bottom of the auxiliary plate 3, the bottom of the trigger plate 4 is slidably matched with the square plate, the suction cup 11 is arranged on the side of the side plate 2 away from the positioning device body 1, the threaded sleeve 12 and the piston column 16 can only slide in the horizontal direction, and the piston column 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 connected to the inside of the threaded sleeve 12.

[0037] In this way, when in use, through the arrangement of the suction cup 11 and the threaded sleeve 12, when the positioning device body 1, the first base plate 5, and the side panel 2 are placed in the armrest box, the threaded sleeve 12 moves in the direction away from the positioning device body 1, so that the suction cup 11 is adsorbed and fits against the inner wall of the armrest box, thereby fixing the side panel 2, avoiding the side panel 2 from sliding in the armrest box when sudden braking or sharp turns occur during vehicle driving, thereby maintaining the stability of the positioning device body 1 on the first base plate 5.

[0038] Further, preferably, the outer periphery of the threaded sleeve 12 is rotatably connected to a mating ring 20, and the mating ring 20 is rotatably set at the center of the side wall of the side plate 2. A gear ring is fixedly set at the outer periphery of the mating ring 20. The threaded sleeve 12 and the mating ring 20 are threadedly connected, and when the mating ring 20 rotates, the threaded sleeve 12 can move horizontally in the mating ring 20.

[0039] Furthermore, preferably, a lifting plate 10 is slidably connected to one side of the side plate 2 away from the positioning device body 1, and an elastic telescopic column 23 is fixedly connected to the bottom of one end of the lifting plate 10 located in the side wall of the side plate 2, and a third tooth plate 22 is arranged at the bottom of the elastic telescopic column 23, and the third tooth plate 22 is arranged on one side of the gear ring and cooperates with the gear ring transmission. A limited stop plate 21 is elastically connected to the side wall of the side plate 2 by a spring, and one end of the bottom of the limited stop plate 21 is slidably cooperated with the top of the third tooth plate 22, and the top of the limited stop plate 21 is slidably cooperated with the lifting plate 10, and a storage groove for accommodating the lifting plate 10 is provided at the top of the side plate 2, and a guide groove for sliding the lifting plate 10 is provided on the side wall of the side plate 2, one end of the bottom of the limited stop plate 21 is provided with an inclined surface facing the lifting plate 10, and one end of the top of the limited stop plate 21 is provided with an inclined surface facing the third tooth plate 22, and one end of the top of the limited stop plate 21 slides into the top of the guide groove.

[0040] During specific use, when the damping ball 8 is installed through the fixed plate 62, the movable plate 63, and the lower mounting assembly, the side plate 2 is in a vertical state relative to the first bottom 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 maximally contracted in the threaded sleeve 12, the bottom of the trigger plate 4 is slidably adapted to the square plate, the spring between the threaded sleeve 12 and the piston column 16 is in a normal state, the lifting plate 10 is in a position close to the threaded sleeve 12, the bottom end of the limit plate 21 is in contact with the top of the third tooth plate 22, and the top end of the limit plate 21 extends into the guide groove. The top of the third tooth plate 22 corresponds to one side of the matching ring 20, and the two are meshed; when the side panel 2 and the first bottom plate 5 are placed in the armrest box, the lifting plate 10 is in contact with both sides of the top of the armrest box, and as the side panel 2 moves downward, the lifting plate 10 is prompted to move upward in the guide groove. The movement of the lifting plate 10 will cause the elastic telescopic column 23 to elastically extend. At this time, since the third tooth plate 22 is limited by the limiting plate 21, the third tooth plate 22 cannot move. When the side panel 2 and the first bottom plate 5 are completely placed in the armrest box, the lifting plate 10 also moves to the top position of the guide groove synchronously. At the same time, the lifting plate 10 acts on the limiting plate 21 to move away from the guide groove. The third toothed plate 22 then moves upward under the action of the elastic telescopic column 23, causing the toothed ring to rotate. The rotation of the toothed ring drives the matching ring 20 to rotate. The rotation of the matching ring 20 causes the threaded sleeve 12 to move away from the positioning device body 1, thereby causing the suction cup 11 to be adsorbed and matched with the inner wall of the armrest box to achieve the limit fixation of the side plate 2, preventing it from moving easily 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 is in the square plate and the trigger plate 4. Under the restriction, it is in a fixed state, and then the spring between the threaded sleeve 12 and the piston column 16 is stretched; when it is necessary to take out the positioning device body 1 and the side panel 2 from the armrest box, pull the auxiliary plate 3 upward, and the auxiliary plate 3 drives the trigger plate 4 to move upward and separate from the square plate, and then the piston column 16 moves toward the suction cup 11 under the action of the spring between it and the threaded sleeve 12. In this process, the piston column 16 compresses the gas between it and the threaded sleeve 12 and transports it to the suction cup 11, so that the suction cup 11 releases the negative pressure adsorption state on the inner wall of the armrest box, and then the side panel 2, the positioning device body 1, and the first bottom plate 5 can be taken out as a whole, which is simple and convenient.

[0041] See also Fig. 9Preferably, a pressure relief member 17 is fixedly connected to the center of one end of the piston column 16 close to the suction cup 11, and the pressure relief member 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 column 16, and the end of the shovel plate close to the piston column 16 is rotatably connected to the positioning rod, and a torsion spring is provided at the rotation connection between the shovel plate and the positioning rod. In the initial state, the shovel plate is kept horizontally relative to the positioning rod under the action of the torsion spring, and an upward arc section is provided at the end of the shovel plate away from the positioning rod, so that when using When the piston column 16 moves toward the suction cup 11, it pushes the positioning rod to move, thereby causing the shovel plate to move toward the inner wall of the armrest box. Subsequently, when the arc segment at the end of the shovel plate contacts the inner wall of the armrest box, as the piston column 16 continues to move and the arc plate and the shovel plate can rotate relative to the positioning rod, the shovel plate will rotate upward relative to the positioning rod, thereby scooping up the upper end of the suction cup 11, thereby avoiding the problem that the suction cup 11 may come into contact and be adsorbed with the armrest box again when the side panel 2 is subsequently lifted from the armrest box.
