Description

Technical Field

[0001] The present invention relates to the technical field of emergency power supplies, and particularly to a field emergency starting power supply. Background Art

[0002] Field operations are when the military conducts operations in the field, which is an indispensable combat mode for troops on the modern battlefield. With the development of technology, more and more modern scientific and technological equipment has been incorporated into field operations. For example, electronic computers required in modern warfare, etc., which integrate command, control, communication, and intelligence, have advanced the command mode to a new stage of automation, greatly improving the command efficiency. However, in field operations, it means that the normal power supply of electronic computers cannot be guaranteed. Then a field emergency starting power supply is needed for emergencies and is also indispensable in field operations.

[0003] In the prior art, a Chinese patent with the publication number "CN116896315A" discloses a field emergency starting power supply. By setting an emergency power supply box body, a storage box, a movable block, an extension frame, an extension rod, and a solar panel, the solar panel can be unfolded and flipped synchronously, which can save the time for opening and flipping, improve the operation efficiency, and can better and more timely carry out work such as communication, issuing of instructions, and transmission of information. It can also fold and flip and store the solar panel synchronously. In case of an emergency, it can save the time for soldiers to pack up the equipment, reserve more reaction time, increase the survival probability during field operations, and also facilitate the neat storage of the solar panel, avoiding damage caused by being squeezed during the storage process due to uneven storage. It solves the problem that the solar panel on the existing field emergency starting power supply cannot be quickly retracted and carried after being unfolded.

[0004] In the above-described solution, through the cooperation of the movable block, the extension frame, and the extension rod, the unfolding and flipping of the solar panel are realized, thus facilitating its folding and flipping storage. However, in this technical solution, the solar panel cannot be adjusted according to the direction of sunlight, resulting in low utilization efficiency of solar energy. And in the prior art, the emergency power supply is stored in a box. Since most of the box doors are installed on the box using relatively complex locks, the operation of opening the box door is rather cumbersome during the opening process, thus causing personnel to be unable to quickly open the box door.

[0035] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0036] Please refer to Figure 1-10 , the present invention is a field emergency starting power supply, including an emergency power supply box body 1. An angle adjustment component is arranged on the side end face of the emergency power supply box body 1. An installation plate 2 is fixedly installed on the angle adjustment component.

The solar panel 3 is protected by the cooperation of the left protection plate 5 and the right protection plate 6. Among them, the emergency power supply box body 1 is used to install the power supply in the prior art. Since the power supply is a technology well-known to those skilled in the art, no specific description will be made here;

[0037] The angle adjustment component includes a support plate 7 fixedly installed on the emergency power supply box body 1. An electric push rod 8 is fixedly installed on the support plate 7.

And personnel can mark the angle degrees on the annular plate 10 to facilitate the accuracy of the angle adjustment of the solar panel 3.

[0038] In this embodiment, when the angle of the solar panel 3 on the mounting plate 2 needs to be adjusted, the electric push rod 8 drives the entire annular support plate 9 to rise, and then the driving motor 16 drives the worm 18 on the output shaft 17 to rotate. By using the cooperation between the worm 18 and the annular worm gear set 11 on the annular support plate 9, and through the limitation of the annular block 13 on the annular groove 12, the entire angle block 14 is adjusted in angle. The angle adjustment of the angle block 14 is used to complete the angle adjustment of the solar panel 3, ensuring that the solar panel 3 always remains consistent with the direction of sunlight, thereby maximizing the utilization efficiency of solar energy and effectively improving the use effect of this field emergency starting power supply.

[0039] The protection component includes four positioning vertical plates 19 fixedly installed on the emergency power supply box body 1. The inner sides of the four positioning vertical plates 19 are respectively provided with lower sliding grooves 20 and translation grooves 21. A sliding shaft 22 is slidably installed inside the translation groove 21. A positioning card slot 23 is provided on the side end face of the left protection plate 5, and a positioning card block 24 is fixedly installed on the side end face of the right protection plate 6. Both the left protection plate 5 and the right protection plate 6 are slidably installed inside the lower sliding groove 20 through the sliding shaft 22. The lower sliding groove 20 is communicated with the translation groove 21, and the positioning card block 24 is inlaid with the positioning card slot 23. The positioning component includes a rotation groove 25, an upper sliding groove 26 and a lower sliding groove 27 provided on the box door 4. A rotating shaft 28 is rotatably installed inside the rotation groove 25. One end of the rotating shaft 28 is fixedly installed with a driving gear 29, and the other end of the rotating shaft 28 is fixedly installed with a rotating handle 30. An upper tooth bar 31 is slidably installed inside the upper sliding groove 26, and a lower tooth bar 32 is slidably installed inside the lower sliding groove 27. Upper positioning holes and lower positioning holes are provided on the inner side face of the emergency power supply box body 1. Both the upper tooth bar 31 and the lower tooth bar 32 are meshed with the driving gear 29. The rotation groove 25 is respectively communicated with the upper sliding groove 26 and the lower sliding groove 27. The position of the rotating handle 30 is on the outer side of the box door 4. A push-pull plate 33 is fixedly installed on the outer side face of the box door 4. A connecting plate 34 is fixedly installed on the side end face of the push-pull plate 33. L-shaped clamping plates 35 are fixedly installed at both ends of the connecting plate 34. An arc-shaped top groove 36 is provided at the end of the L-shaped clamping plate 35. A square groove 37 is provided on the side end face of the positioning vertical plate 19. The L-shaped clamping plate 35 is inside the translation groove 21 through the square groove 37. The arc-shaped top groove 36 is attached to the side end face of the sliding shaft 22. Among them, the upper positioning hole and the lower positioning hole are not on the same horizontal line, and the upper positioning hole is inlaid with the end of the upper tooth bar 31, and the lower positioning hole is inlaid with the end of the lower tooth bar 32, and the inlaid positions of the two have damping force and will not directly fall off without external force.

[0040] In this embodiment, when it is necessary to expose the protected solar panel 3, the handle 30 is rotated to drive the driving gear 29 on the rotating shaft 28 to rotate. Through the cooperation of the driving gear 29 with the upper tooth bar 31 and the lower tooth bar 32, the upper tooth bar 31 is moved out of the upper positioning hole, and the lower tooth bar 32 is moved out of the lower positioning hole. Then, the operator rotates the vertical box door 4 by 90 degrees through the push-pull plate 33 to expose the power supply body inside the box door 4. When the box door 4 rotates, the L-shaped clamping plate 35 in the square groove 37 will follow the rotation of the box door 4 and disengage from the square groove 37. Then, the operator slides the left protection plate 5 and the right protection plate 6 on the sliding shaft 22 in the translation groove 21 and pushes them outward at the same time. When they move to the position of the lower sliding groove 20, the horizontal left protection plate 5 and the right protection plate 6 will rotate by 90 degrees and move vertically downward through the lower sliding groove 20. Through the position movement of the left protection plate 5 and the right protection plate 6, the solar panel 3 on the mounting plate 2 is exposed. At the same time, the left protection plate 5 and the right protection plate 6 can be used to press and fix the rotated box door 4, and the box door 4 is used to increase the stability of the entire emergency power supply box body 1.

[0041] Working principle:

[0042] During use, the handle 30 is rotated to drive the driving gear 29 on the rotating shaft 28 to rotate. Through the cooperation of the driving gear 29 with the upper tooth bar 31 and the lower tooth bar 32, the upper tooth bar 31 is moved out of the upper positioning hole, and the lower tooth bar 32 is moved out of the lower positioning hole. Then, the operator rotates the vertical box door 4 by 90 degrees through the push-pull plate 33 to expose the power supply body inside the box door 4, facilitating the operator to use the power supply body inside the emergency power supply box body 1.

[0043] When the box door 4 rotates, the L-shaped clamping plate 35 in the square groove 37 will follow the rotation of the box door 4 and disengage from the square groove 37. Then, the operator slides the left protection plate 5 and the right protection plate 6 on the sliding shaft 22 in the translation groove 21 and pushes them outward at the same time. When they move to the position of the lower sliding groove 20, the horizontal left protection plate 5 and the right protection plate 6 will rotate by 90 degrees and move vertically downward through the lower sliding groove 20. Through the position movement of the left protection plate 5 and the right protection plate 6, the solar panel 3 on the mounting plate 2 is exposed. At the same time, the left protection plate 5 and the right protection plate 6 can be used to press and fix the rotated box door 4, and the box door 4 is used to increase the stability of the entire emergency power supply box body 1.

[0044] When the angle of the solar panel 3 on the mounting plate 2 needs to be adjusted, the electric push rod 8 drives the entire annular frame plate 9 to rise, and then the drive motor 16 drives the worm 18 on the output shaft 17 to rotate, and the worm 18 cooperates with the annular worm gear group 11 on the annular frame plate 9, and the annular block 13 is limited on the annular groove 12, so that the angle of the entire angle block 14 is adjusted, and the angle adjustment of the angle block 14 is used to complete the angle adjustment of the solar panel 3, ensuring that the solar panel 3 is always consistent with the direction of sunlight, thereby maximizing the utilization efficiency of solar energy and effectively improving the use effect of the field emergency starting power supply.

[0045] In the present technical solution, the inner grooves of the translation groove 21 and the square groove 37 are larger than the L-shaped card plate 35, and the inner tops of the translation groove 21 and the square groove 37 are both set as inclined surfaces, so that the box door 4 can realize the function of flipping. The sliding trajectories of the left protective plate 5 and the right protective plate 6 are accurately calculated: when the left protective plate 5 and the right protective plate 6 move down along the sliding groove 20, their final positions are flush with the outer surface of the box door 4, and the box door 4 rotates 90° to form a horizontal platform, and the end faces of the left protective plate 5 and the right protective plate 6 are close to the lower surface of the box door 4, forming a pressing and fixing effect on the box door 4;

[0046] The meshing angle of the annular worm gear set 11 is strictly limited to the range of ±30°, and a 10mm dynamic gap is reserved between the edge of the solar panel 3 and the inner side of the protective plate. The arc-shaped guide rail structure (annular groove 12) of the angle block 14 ensures that the solar panel 3 only moves in pitch during the adjustment process without lateral displacement, fundamentally avoiding collision with the vertically lowered left protective plate 5 or right protective plate 6; the working order of the entire device is: first start the power supply → then adjust the solar panel 3, and lock the position of the box door 4 after the left protective plate 5 and the right protective plate 6 are lowered. At this time, the electric push rod 8 raises the annular frame plate 9 to make the solar panel 3 leave the protective area, and the worm 18 of the drive motor 16 has a self-locking characteristic, which can maintain the angle stable and not be affected by vibration.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] 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.
