Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1 to 10 As shown, this embodiment proposes a car tire lifting mechanism, including a power source 1, a gearbox 4 and a base 7, a driving gear 2 is installed at the output end of the power source 1, a follower gear 3 is installed on the gearbox 4, the driving gear 2 is meshed with the follower gear 3, both sides of the gearbox 4 are movably hinged with a connecting shaft 512, a differential 6 is installed on the top of the base 7, tire mounting blocks 8 are movably hinged on both sides of the differential 6, the tire mounting block 8 and the upper part of the base 7 are jointly connected with a shock absorber 9, a mounting seat 10 is installed on the top of the base 7, a straight shaft 5 is movably hinged on one side of the base 7, a first cylinder 51 is installed inside the straight shaft 5, a sliding shaft 511 is installed at the output end of the first cylinder 51, one end of the sliding shaft 511 is fixedly connected to the inside of the connecting shaft 512 by a screw, the other end of the sliding shaft 511 is movably hinged inside the mounting seat 10, and the straight shaft 5 is slidably assembled inside the connecting shaft 512;

[0033] A second cylinder 101 is installed inside the mounting base 10, a movable shaft 1011 is installed at the output end of the second cylinder 101, a connecting column 1012 is fixedly connected to the bottom of the movable shaft 1011 by screws, an inner groove frame 1015 is slidably assembled on the outer circumference of the connecting column 1012, the bottom of the inner groove frame 1015 is fixedly connected to the fixed frame 102 by screws, and the bottom of the fixed frame 102 is fixedly connected to the connecting plate 1021 by screws. Through the arrangement of a cylinder, a second cylinder 101 and other structures, when the vehicle needs to lift its tires to wade through water or get out of trouble, the first cylinder 51 and the second cylinder 101 are started synchronously. The first cylinder 51 causes the sliding shaft 511 to slide, driving the connecting shaft 512 to separate from the straight shaft 5. The second cylinder 101 causes the movable shaft 1011 to slide, the fixed frame 102 to separate from the mounting seat 10, the base 7 moves downward, and the tire mounting block 8 is lifted off the chassis. The reaction force is used to lift the vehicle. After reaching the required height, the power source 1 is started in deceleration mode, and the tire mounting block 8 is used to rotate the wheel through gear transmission, thereby improving the vehicle's wading and escape safety.

[0035] In this embodiment, when the tire of the vehicle needs to be lifted to pass through the pond and get out of trouble, the first cylinder 51 and the second cylinder 101 are first started synchronously. The start of the first cylinder 51 causes the sliding shaft 511 to slide, and the sliding of the sliding shaft 511 drives the connecting shaft 512 to separate and unfold from the straight shaft 5. At this time, the second cylinder 101 is started, causing the moving shaft 1011 to slide.

[0036] Example 2

[0037] like Figure 1 to Figure 4As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a servo motor 52 is installed inside the connecting shaft 512, and a plurality of drive shafts 521 evenly distributed around the circumference are rotatably installed inside the connecting shaft 512, one of the drive shafts 521 is connected to the output end of the servo motor 52 through a coupling, an active bevel gear 522 is fixedly sleeved on the outer circumference of the drive shaft 521, a rotating screw 523 is fixedly connected to one end of the drive shaft 521, a plurality of limit rods 524 evenly distributed around the circumference are fixedly connected inside the connecting shaft 512, and a clamping block 525 is movably sleeved on the outer circumference of the limit rod 524 and the rotating screw 523, and the clamping block 525 is slidably assembled Inside the straight shaft 5, a rotating round block 526 is installed for internal rotation of the connecting shaft 512, and a follower inner bevel gear 527 is fixedly connected to the top of the rotating round block 526. Several active bevel gears 522 are meshed with the follower inner bevel gear 527. Through the arrangement of the connecting shaft 512, the straight shaft 5 and other structures, the chassis does not need to be extended. When the connecting shaft 512 is connected to the straight shaft 5, the servo motor 52 is started to drive the active bevel gear 522 to rotate, and the remaining active bevel gears 522 are rotated through the transmission of the follower inner bevel gear 527 and the auxiliary ball 528. The driving shaft 521 rotates to drive the clamping block 525 to extend and clamp the straight shaft 5, and the limit rod 524 assists in limiting, thereby improving the connection stability.

[0038] like Figure 1 to Figure 4 As shown, a plurality of auxiliary balls 528 evenly distributed around the circumference are installed inside the rotating block 526 and the connecting shaft 512 to rotate together.

[0039] In this embodiment, when the chassis does not need to be extended and the connecting shaft 512 is connected to the straight shaft 5, the servo motor 52 is started, and the start of the servo motor 52 drives one of the driving shafts 521 to rotate.

When the follower inner bevel gear 527 rotates, it is rotated by engaging with it. The meshing of the remaining active bevel gears 522 drives the remaining active bevel gears 522 to rotate. The rotation of the active bevel gears 522 causes the remaining driving shafts 521 to rotate. The rotation of the driving shaft 521 drives the rotating screw 523 to rotate. The rotation of the rotating screw 523 drives the clamping block 525 to extend into the interior of the straight shaft 5 for clamping.

By setting structures such as the rotating motor 103 and the touch sensor 1058, when the second cylinder 101 is retracted, the fixed frame 102 slides into the mounting seat 10, and the rotating motor 103 is started. The rotating shaft 104 is rotated through the worm 1032 and the worm wheel 1042, driving the active outer bevel gear 1044 and the transmission bevel gear 1051 to rotate, so that the external frame 1054 extends out and is plugged into the mounting seat 10, and the limiting shaft 1053 is limited. When the touch frame contacts the mounting frame, the sliding spring 1055 and the damper provide protection, and the touch sensor 1058 sends a signal to remind the user to return the chassis to its original position, thereby improving stability.

When the rotating shaft 1031 rotates, the worm 1032 rotates, and the worm 1032 drives the worm wheel 1042 to rotate by meshing with the worm wheel 1042. The rotation of the worm wheel 1042 causes the rotating shaft 104 to rotate. When the rotating shaft 104 rotates, the second bearing 1041 assists its rotation. The rotation of the rotating shaft 104 drives the rotating block 1043 to rotate. The rotating block 1043 is provided with an active outer bevel gear 1044, and the active outer bevel gear 1044 meshes with a plurality of transmission bevel gears 1051. The external frame 1054 is extended outward, and the external frame 1054 is extended and inserted into the interior of the mounting seat 10. When the external frame 1054 is extended, the limit axis 1053 limits it.

When the touch frame 1057 contacts the mounting frame, a sliding spring 1055 and a second damper 1056 provide auxiliary protection when the touch frame contacts the mounting frame. A touch sensor 1058 is provided on the touch frame. When the touch sensor 1058 is fitted with the external frame 1054, the touch sensor 1058 transmits a signal, and the signal is sent to the car computer to remind the user to return the chassis to its position, thereby improving the stability of the equipment.
