[0003] The existing field individual emergency power supply still has the following defects when used:

[0004] 1. In order to meet the needs of portability, traditional field individual emergency power supplies are implemented by adding rollers and pull rods.

DETAILED DESCRIPTION

[0037] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] A portable field emergency power supply for individual soldiers according to a preferred embodiment of the present invention will be described in detail below. Figure 1-5 As shown, a portable field single-soldier emergency power supply includes a frame 1, and heat dissipation grooves 2 are opened at the bottom and left and right sides of the frame 1 to ensure the heat dissipation of the power supply body 8 when in use. The front and rear sides of the bottom of the frame 1 are limitedly rotatably connected with walking wheels 3, and a mounting cylinder 4 is fixedly installed in the gap of the heat dissipation groove 2 at the bottom of the frame 1. A spring 5 is fixedly connected inside the mounting cylinder 4, and the spring 5 passes through the bottom of the frame 1 upward. The top of the spring 5 is fixedly connected to a support plate 6, and a telescopic handle 7 is installed at the rear end of the frame 1. The power supply body 8 is placed inside the frame 1.

[0039] A limiting component 9 is arranged between the front and rear sides of the frame 1 and the top of the power supply body 8. The limiting component 9 is used to fix the power supply body 8 after being placed. A solar charging component 10 is arranged on the top of the limiting component 9. The solar charging component 10 is used to charge the power supply body 8 using solar energy. In addition to being charged by the solar charging component 10, the power supply body 8 can also be charged by a mains charger.

[0040] The traveling wheel 3 includes a single roller symmetrically located on the front side and combined rollers located on the left and right sides of the rear side. The combined rollers are composed of three rollers that are installed concentrically and can rotate independently, so that the vehicle can better pass through rough roads during pulling.

[0041] An interface 81 is provided at the top of the rear side of the power supply body 8. The main body of the interface 81 can be rotated relative to the power supply body 8, so that the interface 81 can be rotated at a certain angle, which is conducive to plugging in at different angles. The types of interface 81 include USB, USB-Type-C, DC 12V, DC 24V, and AC 220V, so that a variety of different power-consuming units can be powered.

[0042] After the power supply body 8 is placed in the frame 1, when it needs to be moved, the frame 1 and the power supply body 8 can be pulled by pulling out the telescopic handle 7 and cooperating with the walking wheel 3. During the movement, through the design of the combined rollers of the rear walking wheel 3, during normal pulling, the two rollers located at the bottom in contact with the ground rotate, and when passing through a relatively rough road surface, the combined rollers can be rotated as a whole during the pulling process to make different rollers work, thereby improving the passability of the frame 1 and the power supply body 8 in the field and ensuring the convenient transfer of the power supply body 8.

[0043] When the power supply body 8 needs to be charged, it can be charged with AC power in urban areas, and with a solar charging component 10 in the wild to increase the endurance of the power supply body 8 in the wild. When in use, through the different types of designs of the interface 81, a variety of different power units can be powered, thereby improving the practicality of the emergency power supply. The rotatable design of the interface 81 body allows plugging in from different angles, which is conducive to stable power supply.

[0044] Furthermore, if Figure 1-3As shown in , 6, the limit assembly 9 includes a rear connecting rod 91, which is symmetrically slidably connected to the left and right sides of the rear side wall of the frame 1, and the top of the rear connecting rod 91 is connected to a cover plate 92 for limiting rotation. The front end of the cover plate 92 is symmetrically fixedly installed with a limit plate 93 on the left and right sides, and the front side wall of the frame 1 is symmetrically slidably connected to the left and right sides of the front connecting rod 94, and a cross bar 95 is fixedly installed between the top ends of the front connecting rod 94. The top of the cross bar 95 is symmetrically connected to the left and right sides of the rotation for limiting rotation.

[0045] The twist block 96 is aligned with the limit plate 93. When the twist block 96 rotates to the rear side, the limit plate 93 is pressed downward to make the cover plate 92 horizontal, so that the cover plate 92 can press the power supply body 8 downward while the twist block 96 can limit the cover plate 92 upward.

[0046] Grooves are provided at the front and rear sides of the frame 1 aligned with the lifting rod 97, and a column penetrating the groove is fixedly installed at the bottom end of the lifting rod 97. The outer side of the column is threadedly connected with a threaded tightening knob 98, so that the lifting rod 97 can be raised and lowered, and the lifting rod 97 can also be limited by squeezing the threaded tightening knob 98 and the outer wall of the frame 1.

[0047] When installing the power supply body 8, first place the power supply body 8 inside the frame 1. After the support plate 6 contacts the inside of the frame 1, the support plate 6 compresses the spring 5 and moves downward. After the placement is completed, the cover plate 92 is moved to the top of the power supply body 8 through the sliding connection of the rear connecting rod 91 on the rear side of the frame 1, and the cover plate 92 is turned over to cover the top of the power supply body 8. Then, the front connecting rod 94 is slidably connected to the front side of the frame 1 to move the cross bar 95 to be flush with the limit plate 93, and then the limit plate 93 and the cover are aligned by rotating the torsion block 96. The plate 92 is limited so that the cover plate 92 stably covers the power supply body 8, and then the cover plate 92 is pressed downward to make the power supply body 8 further press the support plate 6 down a certain distance, and then the lifting rods 97 on the front and rear sides are limited by the threaded tightening knob 98, and then the cover plate 92 and the cross bar 95 are limited, so that the cover plate 92 stably presses the power supply body 8 downward, completing the limited installation of the power supply body 8, and through the action of the support plate 6 and the spring 5, the power supply body 8 can also be buffered during the moving and bumping process to avoid damage to the power supply body 8.

[0048] When the power supply body 8 needs to be taken out, the limit of the limit plate 93 and the cover plate 92 can be released by simply rotating the twist block 96 again. Under the action of the restoring force of the spring 5, the power supply body 8 will be pushed upward and the cover plate 92 will be pushed to flip backward, so that the power supply body 8 can be taken out upward, which is easy to operate.

[0049] Furthermore, if Figure 1 , 7 As shown in Figure 9, the solar charging assembly 10 includes a fixed column 101, the top of the cover plate 92 is fixedly installed with the fixed column 101, the outer periphery of the middle part of the fixed column 101 is fixedly connected with a disk 102, the top of the fixed column 101 is fixedly installed with a threaded column 103, the outer diameter of the threaded column 103 is larger than the diameter of the top of the fixed column 101, so that the rotating drum 104 can be better moved up and down during the rotation process, the outer side of the threaded column 103 is threadedly connected with the rotating drum 104, and the top of the rotating drum 104 is provided with a handle to facilitate the rotation of the rotating drum 104. The outer periphery of the bottom of the tube 104 is connected to a ring 105 for limited rotation, the outer periphery of the disc 102 is connected to a telescopic column 106 for uniform limited sliding, and a transmission rod 107 is connected between the outer periphery of the ring 105 and the top of the telescopic column 106. One end of the transmission rod 107 is hinged to the outer periphery of the ring 105, and the other end is hinged to the top of the outer side of the telescopic column 106, so that during the up and down movement of the ring 105, the telescopic column 106 can be driven to retract inward or expand outward. A solar panel assembly 108 is arranged on the end of the telescopic column 106 away from the disc 102.

[0050] When the solar charging assembly 10 is needed to charge the power supply body 8, the rotating drum 104 is rotated and the threaded connection between the rotating drum 104 and the threaded column 103 is utilized to move the rotating drum 104 downward, thereby driving the ring 105 to move downward. During the downward movement of the ring 105, the transmission rod 107 can be used to drive the telescopic column 106 to move outward, thereby driving the solar panel assembly 108 to expand outward. When charging is stopped, the rotating drum 104 only needs to be reversed to move it upward, so that the solar panel assembly 108 can be retracted inward.

[0051] Furthermore, if Figure 10-12As shown, the solar panel assembly 108 includes a mounting plate 1081, and the mounting plate 1081 is fixedly installed at one end of the telescopic column 106 away from the disc 102, and cylindrical tubes 1082 are fixedly installed on both sides of the mounting plate 1081 away from the end of the telescopic column 106, and the inside of the cylindrical tube 1082 is slidably connected with a telescopic rod 1083, and a slide groove 1084 is fixedly installed on the adjacent side of the cylindrical tube 1082, and the inside of the slide groove 1084 is limitedly slidably connected with a slider 1085, and a central axis 1086 is fixedly installed between the sliders 1085, and a solar panel 1087 is rotatably connected between the outer cylindrical tube 1082 of the central axis 1086, and the central axis 1086 is located in the middle of the solar panel 1087, so that the solar panel 1087 can rotate around the central axis 1086, and the solar panel 1087 is close to the mounting plate 1081. One side is connected to solar panel 2 1088 for limited rotation, the side of solar panel 2 1088 away from solar panel 1 1087 is connected to solar panel 3 1089 for limited rotation between cylindrical tubes 1082, the side of solar panel 1 1087 away from solar panel 2 1088 is connected to solar panel 3 1089 for limited rotation, the side of solar panel 3 1089 away from solar panel 1 1087 is connected to solar panel 1 1087 for limited rotation between telescopic rods 1083, a gear 10810 is fixedly installed in the middle of the side of solar panel 2 1088 close to the mounting plate 1081, a gear 2 10811 is connected in the middle of the mounting plate 1081 for limited rotation, and the gear 2 10811 and the gear 1 10810 are meshed with each other, so that the rotation of the gear 2 10811 can drive the gear 1 10810 to rotate, and a rack 10812 is evenly fixedly installed on the bottom end of the disk 102.

[0052] The rack 10812 is aligned with the telescopic column 106, and the rack 10812 extends outward to mesh with the bottom of the gear 2 10811. Therefore, when the telescopic column 106 drives the mounting plate 1081 and the gear 2 10811 to telescope, when it moves to the teeth of the rack 10812, the gear 2 10811 can rotate.

[0053] During charging, in the process of pushing the telescopic column 106 and the solar panel assembly 108 to move outward, the teeth of the rack 10812 mesh with the gear 2 10811 to drive the gear 2 10811 to rotate, and the gear 2 10811 meshes with the gear 1 10810 to drive the gear 1 10810 to rotate. The fixed installation of the gear 10810 in the middle of the inner side of the solar panel 2 1088 can drive the solar panel 2 1088 to rotate around the inner side. Through the limited rotation connection between the solar panel 2 1088 and the solar panel 3 1089 on both sides of the solar panel 1 1087, the rotation connection of the solar panel 1 1087 around the central axis 1086 in the middle, and the sliding connection of the sliders 1085 at both ends driven by the central axis 1086 in the slide groove 1084, the solar panel 2 1088 can be driven to unfold to a horizontal state (such as ) while rotating.
