[0038] Embodiment 1

[0039] Reference Figure 1 and 7The present invention provides a technical solution: a mobile structure includes a mobile base 1 and mobile wheel frames 2 installed at both ends of the mobile base 1, two mobile wheel groups 3 are installed on the two mobile wheel frames 2 to realize the basic mobile function of the mobile structure, and the mobile wheel groups 3 include a connecting frame 31 and two wheels 32 installed on the connecting frame 31.

[0040] Reference Figure 1 and 7 A control mechanism 4 for controlling the retraction and extension of the moving wheel group 3 is arranged between the moving wheel group 3 and the moving wheel frame 2. Specifically, there are four groups of control mechanisms 4, that is, each moving wheel group 3 is configured with a group of control mechanisms 4, and each group of control mechanisms 4 includes a first control rod 41 for controlling the retraction and extension of the moving wheel frame 2 and a second control rod 42 for controlling the retraction and extension of the connecting frame 31. The two ends of the first control rod 41 are respectively hinged to the moving wheel frame 2 and the moving base 1, and the two ends of the second control rod 42 are respectively hinged to the moving wheel frame 2 and the connecting frame 31. The first control rod 41 and the second control rod 42 are both electrically controlled telescopic rods. When loading equipment, the external equipment power supply provides electrical energy to the telescopic rod to ensure its normal operation.

[0041] Reference Figure 1-3 A support seat 6 for loading equipment is arranged on the upper side of the mobile base 1, and a telescopic mechanism 5 for reducing vibration is arranged between the support seat 6 and the mobile base 1. Specifically, the telescopic mechanism 5 includes a fixed tube 51 and a support rod 52 slidably fitted in the fixed tube 51. Two first partitions 54 and second partitions 55 distributed up and down are arranged on the tube wall of the fixed tube 51. The first partition 54 and the second partition 55 divide the fixed tube 51 into an upper air cavity, a connecting cavity and a lower air cavity. The first partition 54 is an annular plate composed of a plurality of fan-shaped plates, and the middle of the first partition 54 is fitted with a support rod 52 installed at the bottom of the support rod 52. A friction ball 53 is provided at the end, and a telescopic spring 56 is connected between the bottom of the friction ball 53 and the second partition plate 55. A vent hole connecting the lower air cavity and the connecting cavity is provided on the second partition plate 55, and a damping hole 57 is provided on the cavity wall of the lower air cavity. When working, the connection between the support seat 6 and the movable base 1 is an elastic connection. When bumpy, the four-fold buffering force of the friction between the friction ball 53 and the first partition plate 54, the elastic force of the first partition plate 54, the restoring force of the telescopic spring 56 after being compressed, and the resistance of the gas passing through the damping hole 57 can effectively buffer the vibration and protect the overall stability.

[0042] Reference Figure 4 The multiple fan-shaped plates of the first partition 54 are all elastic plates, and the inner arc edge of the fan-shaped plate is a C-shaped arc edge to avoid a stuck state between the friction ball 53. The diameter of the inner ring of the annular ring formed by the fan-shaped plate in the natural state is smaller than the ball diameter of the friction ball 53, ensuring that the friction ball 53 will definitely come into contact with the first partition 54 to generate friction during the up and down bumping process.

[0043] Reference Figure 1and 6 Two symmetrically distributed hollow cavities are provided in the support seat 6, and a dust-proof heat dissipation mechanism 7 for loading equipment on the support seat 6 is installed in the hollow cavity. The dust-proof heat dissipation mechanism 7 includes a horizontal axis 71 rotatably installed in the hollow layer, and a coil spring 72 is provided at the connection between the two ends. A dust-proof roll plate 73 and two gears 74 are provided on the horizontal axis 71, and the dust-proof roll plate 73 is located between the two gears 74. A heat dissipation port is opened at the bottom of one side of the horizontal axis 71 of the hollow layer, and a dust-proof net 75 for dust prevention is installed in the heat dissipation port. Guide frames 76 are installed on the two opposite side edges of the heat dissipation port. When the dust-proof roll plate 73 is extended outward, the side edge extends along the guide frame 76, and the end of the winding end is tied with a wire rope 77, and the other end of the wire rope 77 passes through the movable base 1 and is tied to the movable wheel frame 2, so that the movement of the movable wheel frame 2 will pull the wire rope 77 to carry out subsequent movements.

[0044] Reference Figure 3 The support seat 6 is provided with an O-shaped metal ring 78 at the outlet of the steel wire rope 77 to prevent the steel wire rope 77 from getting stuck during the pulling process, and the support seat 6 is fixed with a dustproof sponge 79 on the lower side of the metal sealing ring, which is sleeved on the outside of the steel wire rope 77, to prevent dust from entering the hollow layer through the O-shaped metal ring 78.

[0045] Reference Figure 1 and 5 A buffer shock-absorbing device 8 is arranged between the dust-proof and heat-dissipating mechanism 7 and the mobile wheel frame 2 for buffering the vibration generated during the movement. Specifically, the buffer shock-absorbing device 8 includes a vertical rod 81 arranged on one side of the gear 74, and a tooth groove matching the gear 74 is opened on the side of the vertical rod 81. A sliding groove matching the vertical rod 81 is opened on the mobile base 1. The lower end of the vertical rod 81 passes through the sliding groove and is connected to a shock-absorbing spring 82. A circular gasket 84 is installed at the bottom end of the shock-absorbing spring 82. A telescopic hose 83 is arranged between the circular gasket 84 and the vertical rod 81, and the telescopic hose 83 is wrapped around the outside of the spring. The telescopic hose 83 plays a protective role. Two buffer gaskets 9 are arranged on the two mobile wheel frames 2, and the buffer gaskets 9 are located directly below the vertical rod 81 on the same side, so that the circular gasket 84 just rests on the buffer gasket 9 after the vertical rod 81 descends.

[0046] The working process of the mobile structure provided in this embodiment is as follows:

[0047] The mobile structure has two use states: moving and stationary. The first control rod 41 and the second control rod 42 of the control mechanism 4 push and pull the moving wheel frame 2 and the moving wheel group 3 respectively to achieve the state switching. The working power of the control mechanism 4 is provided by the loaded product. When switching to the mobile state: the moving wheel frame 2 is pushed outward and rotated to unfold. When unfolding, the wire rope 77 will be gradually pulled out of the support seat 6, thereby pulling the dust roll plate 73 to unfold along the guide frame 76. At the same time, the horizontal shaft 71 rotates with the gear 74 thereon. The gear 74 is engaged with the tooth groove on the vertical rod 81, so that the vertical rod 81 moves downward with the entire buffer shock absorbing device 8 until the moving wheel frame 2 is completely rotated to the vertical state (refer to Figure 1 );

[0048] When switching to the stationary state: by controlling the contraction of the first control rod 41 and the second control rod 42, the moving wheel frame 2 and the moving wheel group 3 are pulled inward and retracted, the horizontal shaft 71 rotates in the opposite direction under the action of the coil springs 72 at both ends, pulling the dust roll plate 73 to retract, and the length of the wire rope 77 that has been pulled out is retracted into the support seat 6, and when the gear 74 on the horizontal shaft 71 rotates in the opposite direction with it, the vertical rod 81 and the entire buffer shock absorbing device 8 are driven to move upward through the meshing of the teeth, leaving space for the retraction of the moving wheel frame 2, until the moving wheel frame 2 and the moving wheel group 3 are completely retracted to the horizontal state, the action is ended, and the state switching is completed (refer to Figure 6-7 ).

[0049] Embodiment 2

[0050] Reference Figure 8-10 The energy storage power supply based on the mobile structure in the first embodiment includes a metal shell 10 installed on the support seat 6. The metal shell 10 includes a rectangular shell composed of four panels of front, back, left and right and an upper top plate and a lower bottom plate. The front panel is provided with a liquid crystal touch screen 12, a main power switch 13, a 120V AC output socket 14, and a 240V AC output socket 15 from top to bottom, which can stably output two AC voltages of 120V and 240V. The rear panel is provided with a heat dissipation window, an AC output PV input circuit breaker 16, a 20A AC charging input socket 17, a photovoltaic charging input socket 18, an EV AC charging input interface 19, an expansion battery interface 20, and a grounding screw column 21 from top to bottom, and a mobile handle 11 is provided on the upper part of the front panel and the rear panel. A lithium iron phosphate power supply component is installed inside the metal shell 10. The energy storage power supply can supply power to the outside through the lithium iron phosphate power supply component, which has high safety, and can also be supplied by photovoltaic and mains access.

[0051] In this embodiment: the housing of the energy storage power supply is a metal housing 10, and the protection safety is guaranteed. The power supply has the output function of two AC power supplies of 120V and 240V. After the battery voltage is used up, the battery can be charged by the mains or photovoltaic panels, and the LCD touch display screen 12 can be used;

[0052] After the energy storage power source is loaded on the support seat 6, the control mechanism 4 is powered by the energy storage power source to obtain action energy. When switching to the mobile state, the entire device can be pushed by moving the handle 11. In the mobile structure in this state, the dust roll plate 73 completely blocks the heat dissipation port to prevent the flying dust from entering the support seat 6 during movement. At the same time, the circular washer at the lower end of the vertical rod 81 is in contact with the shock-absorbing cushion on the moving wheel frame 2, so that it and the telescopic mechanism 5 can play a shock-absorbing role together. When the movement generates vibration and bumps, the friction ball 53 in the telescopic mechanism 5 repeatedly compresses the first partition plate 54, the telescopic spring 56 and the air at the bottom of the fixed tube 51, thereby utilizing The friction between the friction ball 53 and the first partition plate 54, the anti-deformation force of the first partition plate 54, the restoring force of the telescopic spring 56 and the resistance of the air passing through the damping hole 57 are four forces to reduce vibration. The four-fold shock absorption in the telescopic mechanism 5 is the main shock absorption component of the mobile structure, and the buffer shock absorption device 8 on the outside is an auxiliary shock absorption component, which reduces vibration through the restoring force of the shock absorption spring 82. The cooperation of the main shock absorption component and the auxiliary shock absorption component greatly reduces the vibration of the mobile structure during the movement, thereby protecting the energy storage power supply loaded on the mobile structure, avoiding damage to the precision components therein, and ensuring the safety of use;

[0053] In the static state, the dustproof roll plate 73 on the dustproof and heat dissipation mechanism 7 is retracted and the heat dissipation port is opened. The energy storage power supply ensures that a part of the heat generated by the energy storage power supply in the working state can be conducted and dissipated from the bottom, thereby increasing its heat dissipation efficiency. If the energy storage power supply needs to be moved when it is not working, the vibration caused by the movement is mainly buffered by the components in the telescopic mechanism 5, which also ensures the stability of the energy storage power supply.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
