Detailed Embodiments

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to the attached Figures 1-6 , and the following technical solutions are provided in this application.

[0029] Embodiment 1: A mobile electric box with a safety base, including an electric box housing 1. A hand-pulled telescopic frame 2 is provided on one side of the electric box housing 1. A safety base 4 is horizontally inserted and fixed at the lower end of the electric box housing 1. Two moving wheels 3 are provided on one side of the lower end of the safety base 4 through a buffer support assembly. The buffer support assembly includes a shock-absorbing wheel seat 7 and a plurality of arc-shaped guide rods 9. The shock-absorbing wheel seat 7 is movably inserted into one side of the safety base 4. The two moving wheels 3 are respectively vertically arranged on both sides of the shock-absorbing wheel seat 7. A reciprocating slot 5 is opened at the lower end of the safety base 4 near the hand-pulled telescopic frame 2. A reference shaft 6 is horizontally arranged on the side of the reciprocating slot 5 away from the hand-pulled telescopic frame 2. The shock-absorbing wheel seat 7 is placed in the reciprocating slot 5 and one side is movably sleeved on the reference shaft 6. The shock-absorbing wheel seat 7 is kept inserted into the reciprocating slot 5 on one side through the reference shaft 6, and the other side can be rotated and moved out of the reciprocating slot 5, and then the moving wheel 3 is installed on one side of the movable shock-absorbing wheel seat 7.

[0030] A bearing platform is horizontally arranged on the side of the shock-absorbing wheel seat 7 outside the reciprocating slot 5. A wheel shaft 11 is horizontally inserted through the center of the bearing platform through a bearing. The two moving wheels 3 are respectively sleeved on both sides of the wheel shaft 11 passing through the bearing platform, and the two moving wheels 3 on both sides are located on both sides of the electric box housing 1. A plurality of arc-shaped guide rods 9 are symmetrically arranged on the side of the reciprocating slot 5 close to the shock-absorbing wheel seat 7. Arc-shaped guide grooves 8 are opened on the side of the shock-absorbing wheel seat 7 close to the arc-shaped guide rods 9. A plurality of arc-shaped guide rods 9 are respectively movably inserted into a plurality of arc-shaped guide grooves 8 and are provided with anti-detachment blocks. Buffer springs 10 are sleeved on the sides of the arc-shaped guide rods 9 located in the reciprocating slot 5. The virtual axis of the arc-shaped guide rod 9 is coaxially arranged with the virtual axis of the arc-shaped guide groove 8. The depth of the reciprocating slot 5 is greater than the thickness of the shock-absorbing wheel seat 7. The matching design of the arc-shaped guide rod 9 and the arc-shaped guide groove 8 can prevent the shock-absorbing wheel seat 7 from completely detaching from the reciprocating slot 5. Then, through the elastic support of the buffer spring 10, when the moving wheel 3 walks on a bumpy ground, the electric box housing 1 can be appropriately buffered and shock-absorbed.

[0031] On one side of the bearing platform of the shock-absorbing wheel seat 7 close to the hand-pulled telescopic frame 2, there is an elastic anti-collision plate 28. When the shock-absorbing wheel seat 7 rotates along the reference axis 6, the elastic anti-collision plate 28 will not contact the side of the electric box housing 1. When the electric box housing 1 is manually pushed and pulled through the hand-pulled telescopic frame 2, the electric box housing 1 is in an inclined posture. At this time, the shock-absorbing wheel seat 7 elastically extends a certain distance into the reciprocating slot 5. Coupled with the self-inclination of the electric box housing 1, the elastic anti-collision plate 28 can preferentially contact the ground obstacles in the walking direction of the electric box housing 1, and then cooperate with the elastic movement of the shock-absorbing wheel seat 7 to absorb shock, avoiding excessive impact on the electric box housing 1.

[0032] A heat dissipation component is provided to dissipate heat from the space inside the electric box housing 1. The heat dissipation component is arranged on the side of the safety base 4 away from the shock-absorbing wheel seat 7. The heat dissipation component includes a switching baffle 14 and a air supply mounting seat 18. The safety base 4 has a heat dissipation cavity vertically penetratingly opened at the upper end inside the electric box housing 1. A number of first air holes 15 are vertically penetrated and opened in the heat dissipation cavity. On one side of the lower end of the safety base 4, a groove is horizontally opened. Two horizontal sliding grooves 13 are symmetrically opened on both sides inside the groove. The lower ends of a number of first air holes 15 are respectively communicated with the horizontal sliding grooves 13. The switching baffle 14 is horizontally placed in the groove and slidably inserted into the two horizontal sliding grooves 13 on both sides. A number of second air holes 16 are vertically symmetrically opened at the upper end of the switching baffle 14. A number of second air holes 16 are arranged corresponding to a number of first air holes 15. When the first air holes 15 are docked with the second air holes 16, the air inside the electric box housing 1 is communicated with the outside, which is beneficial to air flow and exchange. On the contrary, it is blocked to prevent external pollutants from entering the electric box housing 1. And the design of the first air holes 15 and the second air holes 16 at the bottom avoids the influence of external rain, snow, dusty and other environments on the electric box housing 1.

[0033] A shock-absorbing wheel seat 7 is arranged on one side of the heat dissipation cavity of the safety base 4 away from the reciprocating slot 5. Two air supply docking holes 20 are vertically penetrated and opened at the lower end inside the shock-absorbing wheel seat 7. At the lower end on one side of the switching baffle 14 located in the air flow cavity 17, there is an air supply mounting seat 18. Two feet 25 are symmetrically arranged at the lower end of the air supply mounting seat 18. L-shaped air supply grooves 19 are opened on both sides of the air supply mounting seat 18. The vertical sections of the two L-shaped air supply grooves 19 are arranged corresponding to the two air supply docking holes 20. Air supply fans 21 are inserted into the horizontal sections of the two L-shaped air supply grooves 19. The air supply fans 21 actively send the external air into the electric box housing 1 through the air supply docking holes 20, and then after circulating around the inside of the electric box housing 1 from the air flow cavity 17, it is discharged from the positions of the first air holes 15 and the second air holes 16 to complete air flow heat dissipation.

[0034] Embodiment 2: On the basis of Embodiment 1, a matching positioning component is provided to position the position states of the shock-absorbing wheel seat 7 and the switching baffle 14. The matching positioning component includes two positioning inserts 22, and the two positioning inserts 22 are inserted on one side of the switching baffle 14. L-shaped restraint plates 26 are provided on both sides of the safety base 4 close to the air supply mounting seat 18, and magnetic attraction blocks 27 are provided on one side of the air supply mounting seat 18 close to the L-shaped restraint plate 26. The width of one side of the L-shaped restraint plate 26 is greater than the diameter of the L-shaped air supply groove 19. When the second air hole 16 is misaligned with the first air hole 15 and the L-shaped air supply groove 19 is misaligned with the air supply docking hole 20, both sides of the L-shaped restraint plate 26 are respectively in contact with the magnetic attraction block 27 and block the L-shaped air supply groove 19. The L-shaped restraint plate 26 can restrain the switching baffle 14 to prevent the switching baffle 14 from detaching from the safety base 4. When the first air hole 15 and the second air hole 16 are misaligned, the L-shaped restraint plate 26 can block the two L-shaped air supply grooves 19 on both sides of the air supply mounting seat 18, and then self-fix and hold through the adsorption of the magnetic attraction block 27 and the L-shaped restraint plate 26 to ensure the sealing of the first air hole 15 and the air supply docking hole 20 during the movement of the electrical box housing 1.

[0035] The horizontal sliding groove 13 and the groove are both communicated with the reciprocating slot 5. Two manual telescopic frames 2 are symmetrically arranged at the upper end of the switching baffle 14 close to the reciprocating slot 5. The two positioning inserts 22 are symmetrically arranged on one side of the shock-absorbing wheel seat 7 close to the reference shaft 6. The lower end side of the positioning insert 22 away from the bearing table is an inclined surface. When the first air hole 15 is docked with the second air hole 16 and the L-shaped air supply groove 19 is docked with the air supply docking hole 20, the two positioning inserts 22 are respectively inserted into the two positioning slots 23. When the power module in the electrical box housing 1 is in the discharging posture, press the electrical box housing 1 to retract the shock-absorbing wheel seat 7 into the reciprocating slot 5. At this time, horizontally push the switching baffle 14 to insert the positioning insert 22 into the positioning slot 23. At this time, the switching baffle 14 cannot release the docking of the first air hole 15 and the second air hole 16. At the same time, the electrical box housing 1 maintains a horizontal posture under the support of the moving wheels 3 and the floor feet 25. In addition, when the electrical box housing 1 is discharging, if an internal thermal runaway occurs, the flame and hot air are ejected from the lower part of the electrical box housing 1, avoiding directly spraying towards the surrounding operators and improving safety.

[0036] When it is necessary to disengage the positioning insert 22 from the positioning slot 23, further press the side of the electrical box housing 1 where the shock-absorbing wheel seat 7 is located, so that the positioning insert 22 rotates along with the shock-absorbing wheel seat 7 away from the positioning slot 23 along the reference shaft 6. At this time, pull the switching baffle 14 forcefully to make the magnetic attraction block 27 on one side of the air supply mounting seat 18 in magnetic contact with the L-shaped restraint plate 26 to hold.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
