[0002] The mobile wheel set is an important part of mechanical equipment, and it plays a key role in many fields. The mobile wheel set refers to the set of wheels and related components installed at the bottom of the mechanical equipment to support and move the equipment. Its main functions include: supporting equipment: the mobile wheel set can bear the weight of the equipment and disperse it on the ground to protect the equipment and the ground; moving equipment: through the rolling of the wheels, the mobile wheel set can easily move the equipment so that it can operate at the required position. The mobile wheel set is usually composed of wheels, bearings, shafts, brackets and other components. Among them, the wheel is the most critical component. Its material, size and shape and other parameters directly affect the performance and service life of the wheel set. With the advancement of science and technology and the development of industrialization, the mobile wheel set technology is also constantly innovating and improving, using new materials and optimized design to reduce the weight of the mobile wheel set, improve the mobile performance and energy saving effect of the equipment; integrate intelligent components such as sensors and controllers to realize the functions of autonomous navigation and automatic obstacle avoidance of the mobile wheel set; develop mobile wheel sets with multiple functions, such as combined wheel sets that can realize the functions of moving, lifting, rotating, etc. at the same time; use low-energy consumption, low-noise drive devices and environmentally friendly materials to reduce the impact of mobile wheel sets on the environment.

[0003] The mobile wheel group plays an important role in mechanical equipment. The mobile wheel group is a tool for supporting and moving the equipment. When the equipment is moved, the mobile wheel group is easily affected by the road surface and causes the equipment to shake.

[0037] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0038] like Figure 1-10 As shown, the mobile wheel assembly for improving mobile safety comprises:

[0039] A linkage mechanism 100, wherein the linkage mechanism 100 is rotatably connected to the bottom of the base of the device to be installed, and two mounting mechanisms 200 are fixedly installed at the bottom of the linkage mechanism 100; a locking mechanism 300 is provided below the mounting mechanism 200, and the locking mechanism 300 is composed of a wheel seat 301, a transmission mechanism 400 is rotatably connected to the bottom of the wheel seat 301, and a transmission mechanism 400 is fixedly installed on the top of the wheel seat 301, and the transmission mechanism 400 is movably sleeved inside the mounting mechanism 200, and the top of the wheel seat 301 is connected to the mounting mechanism 200 via a buffer spring 204.

[0040] In the present technical solution, the linkage mechanism 100 is installed under the base of the equipment to be installed, so that the linkage mechanism 100 can drive the connecting plate 103 to rotate, so that the long plate 101 swings and then drives the walking mechanism 500 to adjust the spacing. The distance between two adjacent walking mechanisms 500 is adjusted according to the position of the obstacle during the walking process, so as to improve the obstacle avoidance function of the moving wheel assembly. When an obstacle that cannot be avoided occurs, the contact pressure between the roller 504 and the ground can be adjusted by adjusting the internal air pressure of the fixed tube 202, so that the pressure of multiple rollers 504 is balanced to improve the movement stability, and the moving wheel assembly is coordinated with the universal wheel to realize the movement of the equipment, thereby improving the convenience of using the moving wheel assembly.

[0041] The linkage mechanism 100 includes a long strip 101 and a connecting plate 103. The number of the long strips 101 is two and they are distributed in parallel. Both ends of the long strip 101 are movably connected to one end of the connecting plate 103 through a connecting piece 102. The number of the connecting plates 103 is two, and the two connecting plates 103 and the long strip 101 are rotatably connected to each other end to end. The middle parts of the two connecting plates 103 are fixedly connected to a fixed shaft 104, and the fixed shaft 104 is rotatably connected to the inside of the bottom plate 105, and a worm gear 107 is fixedly connected to the top of the fixed shaft 104; a plurality of mounting holes 106 are opened on the edge of the bottom plate 105, and the bottom plate 105 is fixedly connected to the base of the device to be installed through screws in the mounting holes 106. The fixed shaft 104 is rotatably connected to the bottom plate 105. The base of the installation equipment is inserted through, and the top of the base of the equipment to be installed is rotatably connected to the worm 108. The two ends of the worm 108 are respectively meshed with two worm wheels 107. One end of the worm 108 is fixedly connected to the driving structure, and the driving structure is fixedly installed to the top of the base of the equipment to be installed. The bottom of the long board 101 is fixedly installed with a corresponding distribution of the walking mechanism 500, and the top of the wheel seat 301 is fixedly connected to two guide rods 406. The two guide rods 406 are symmetrically distributed on both sides of the fixed tube 202. Each of the guide rods 406 is inserted through the inside of the enclosure 203, and the guide rods 406 are located in the infrared sensor 109 inside the buffer spring 204, and the infrared sensor 109 is electrically connected to the controller of the driving structure.

[0042] In the present technical scheme, the base plate 105 is installed at the base of the equipment to be installed, and after being fixed by screws in the mounting hole 106, the fixed shaft 104 is moved above the base. At this time, when the worm 108 is driven to rotate by the driving structure, the worm 108 drives the worm wheel 107 to rotate, and then the worm wheel 107 drives the fixed shaft 104 to rotate inside the base plate 105. When the fixed shaft 104 rotates, it drives the connecting plate 103 to rotate, so that the connecting plate 103 drives the long strip 101 to rotate. When the connecting plate 103 rotates, the long strip 101 uses the same direction as the travel direction, and when the connecting plate 103 rotates to a horizontal or vertical state, the distance between the two rollers 504 on the same side changes. The infrared sensor 109 senses the obstacle in front. When avoiding the obstacle, the roller 504 is driven to adjust its position, so as to achieve a smooth obstacle avoidance function and ensure the stability of the moving wheel group during the travel.

[0043] The mounting mechanism 200 includes a mounting plate 201, which is fixedly connected to the middle part of the bottom end of the long plate 101 by bolts, a hollow fixed tube 202 is fixedly connected to the bottom of the mounting plate 201, a shroud 203 is fixedly connected to the top outer surface of the fixed tube 202, and the shroud 203 is connected to the top surface of the wheel shell by a buffer spring 204, and the buffer spring 204 is sleeved on the surface of the fixed tube 202, an L-shaped guide plate 205 is fixedly connected to one side of the mounting plate 201, and a delivery pipe 206 is provided on the other side of the mounting plate 201, the delivery pipe 206 is connected to the inside of the fixed tube 202 through and through, and the connection between the delivery pipe 206 and the fixed tube 202 is located above the shroud 203, and one end of the delivery pipe 206 is connected to the air pump.

[0044] In the present technical solution, the fixed tube 202 is fixed to the bottom of the long board 101 by bolts on the mounting plate 201. When the wheel seat 301 moves on a bumpy road surface, the wheel seat 301 drives the transmission mechanism 400 to move inside the fixed tube 202. At this time, the buffer spring 204 is compressed to play a buffering protection function. When the transmission mechanism 400 moves inside the fixed tube 202, the air pressure inside the fixed tube 202 changes. At this time, gas is transported to the inside of the fixed tube 202 through the delivery pipe 206 for air pressure adjustment, thereby controlling the deformation of the buffer spring 204. The movement amount between the wheel seat 301 and the long board 101 during shaking can be controlled. The hose 311 is limited by the guide plate 205 to avoid contact between the hose 311 and the buffer spring 204, thereby improving the safety performance of the moving wheel group.

[0045] The locking mechanism 300 also includes a flange 302, which is fixedly connected to one side of the wheel seat 301, and a support rod 303 is fixedly connected to the bottom of the flange 302. The bottom of the support rod 303 is rotatably connected to a pressure plate 304. The pressure plate 304 is a bent structure. Both sides of one end of the pressure plate 304 are connected to the support rod 303. The other end of the pressure plate 304 extends to the inside of the wheel seat 301 and is located above the walking mechanism 500. The bottom of the pressure plate 304 is fixedly connected to The anti-slip teeth 305 are arranged corresponding to the walking mechanism 500. The top of the wheel seat 301 is fixedly connected to two guide rods 406. The two guide rods 406 are symmetrically distributed on both sides of the fixed tube 202. Each guide rod 406 is inserted through the inside of the enclosure 203, and the guide rod 406 is located inside the buffer spring 204. Both sides of the convex edge 302 are rotatably connected to the limit rods 307. The number of the limit rods 307 is two and both are L-shaped structure, the two limit rods 307 are symmetrically distributed on both sides of the pressure plate 304, the horizontal end of the bottom of the limit rod 307 is in contact with the bottom surface of the pressure plate 304, and a connecting structure is provided between the two limit rods 307; the connecting structure includes an outer sleeve 308 and a piston rod 309, both ends of the outer sleeve 308 are sealed and sleeved with the piston rod 309, the end of the piston rod 309 located outside the outer sleeve 308 is rotatably connected to the top of the limit rod 307, the other end of the piston rod 309 is fixedly connected with a piston located inside the outer sleeve 308, and the piston and the inner part of the outer sleeve 308 are sealed and slidable, the top of the outer sleeve 308 is fixedly connected to the intake pipe 310 of the U-shaped structure, the two ends of the intake pipe 310 are respectively located on both sides of the two pistons, the top of the intake pipe 310 is connected to the delivery pipe 206 through a hose 311, the bottom of the hose 311 is fixedly connected to the valve 312, and the intake pipe 310 is movably sleeved with the inside of the guide plate 205.

[0046] In the present technical solution, during the movement, the position of the pressure plate 304 is limited by the limiting rod 307, so that the movable plug 402 is in a static state. When the gas is delivered to the inside of the fixed tube 202 by the air pump, the air pressure formed is used to adjust the expansion and contraction amount of the buffer spring 204. After the device is moved into place by the moving wheel assembly, when the gas is delivered to the inside of the delivery tube 206 by the air pump, the delivery tube 206 delivers the gas to the fixed tube 202, so that the movable plug 402 moves to the bottom. At this time, the wheel seat 301 and the fixed tube 202 are in a relatively fixed state, ensuring the rigid support of the device after the movement. At the same time, the valve 312 is opened to allow the gas to flow from the hose 31 1 and the air inlet pipe 310 enter the outer sleeve 308, the positive pressure formed inside the outer sleeve 308 pushes the piston rod 309 to move toward the center of the outer sleeve 308, so that the piston rod 309 pulls the limiting rod 307 and moves. At this time, the limiting rod 307 is separated from the bottom of the pressure plate 304. At this time, the positive pressure formed inside the fixed tube 202 pushes the sealing plug 403 to move downward, so that the sealing plug 403 pushes the pressure plate 304 to rotate through the connecting rod 404 and the connecting rod 405. The pressure plate 304 overcomes the elasticity of the tension spring 306 and rotates around the bottom end of the support rod 303, driving the anti-skid teeth 305 to press on the surface of the roller 504, realizing the limiting of the roller 504, and ensuring that the position of the moving wheel assembly is locked after moving.

[0047] The transmission mechanism 400 includes a connecting tube 401, which is fixedly connected to the top of the wheel seat 301, passes through the bottom of the fixed tube 202 and extends to the inside of the fixed tube 202, and the top of the connecting tube 401 located inside the fixed tube 202 is fixedly connected to the movable plug 402, and the movable plug 402 is sealed and slid with the inner wall of the fixed tube 202, and the middle parts of the connecting tube 401 and the movable plug 402 are provided with through holes that are interconnected; the connecting tube 401 passes through the wheel seat 301 and is connected to the inside of the wheel seat 301, and a connecting rod 404 is provided inside the connecting tube 401, and the top of the connecting rod 404 is fixedly connected to the sealing plug 403, and the sealing plug 403 is sealed and slid with the inner wall of the connecting tube 401, and the bottom of the connecting rod 404 is rotatably connected to the connecting rod 405, and the connecting rod 405 is rotatably connected to the pressure plate 304.

[0048] In the present technical solution, the wheel seat 301 drives the connecting tube 401 and the movable plug 402 to move inside the fixed tube 202 when it moves. When vibration occurs, the movable plug 402 and the connecting tube 401 move inside the fixed tube 202. When the limiting rod 307 limits the pressure plate 304, the sealing plug 403 is in a stationary state, thereby realizing the smooth lifting and lowering of the connecting tube 401.

[0049] The walking mechanism 500 includes a rotation, the rotating shaft 501 is fixedly connected to the bottom of the wheel seat 301, the wheel seat 301 is a U-shaped structure, a roller 504 is provided inside the wheel seat 301, the roller 504 is an annular structure, and the inner wall of the roller 504 is fixedly connected to the bearing 502 through the pressure sensor 503, and the bearing 502 is rotatably connected to the surface of the rotating shaft 501.

[0050] In the present technical solution, the pressure value generated by the roller 504 when walking is detected by the pressure sensor 503. When the pressure value decreases, gas is transported into the fixed tube 202, so that the generated air pressure pushes the wheel seat 301 to move downward. When the rated pressure value increases, the air in the fixed tube 202 is extracted through the delivery tube 206, so that the pressure of multiple wheel seats 301 is balanced to ensure safety during the travel. Similarly, when encountering potholes, the pressure of the corresponding roller 504 is reduced. At this time, the generated air pressure is used to push the roller 504 to move downward to achieve pressure balance. When encountering a raised obstacle, the pressure increases when the roller 504 contacts the obstacle. At this time, after the air pressure decreases, the roller 504 shrinks upward, thereby achieving the balance of the roller 504, realizing the stable travel of the mobile wheel group, and effectively improving the safety performance.
