Description

Technical Field

[0001] The invention relates to the technical field of power supplies, and in particular discloses a portable energy storage power supply. Background Art

[0002] With the continuous advancement of battery technology, the energy density of each battery cell has been significantly improved, which not only enables energy storage power supplies to store more electricity, but also greatly reduces their weight and volume, thereby enhancing their portability. This technological improvement enables portable energy storage power supplies to better meet the high power demand in outdoor activities, and therefore is widely popular among outdoor enthusiasts.

[0003] However, the outdoor environment is complex and changeable. When energy storage power supplies are used outdoors, they are more susceptible to external force damage such as impact or collision than in other scenarios. Therefore, it is particularly necessary to provide effective anti-collision protection for energy storage power supplies to improve their safety. At present, the most common anti-collision protection method only uses springs as buffer elements. Obviously, its defects are obvious: when the spring absorbs the impact force and releases it, at least half of the reaction force will be transmitted back to the energy storage power supply itself, and the anti-collision effect is poor; in addition, the energy absorption range of the spring is limited, which restricts its anti-collision ability and cannot fully cope with various complex impact situations.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment: A portable energy storage power source, see Figure 1-Figure 2 , comprising: a housing 1; a battery pack 2 fixedly mounted in the housing 1; a terminal block 3 fixedly mounted on the housing 1, the terminal block 3 being connected to the battery pack 2; See also Figure 2 , Figure 3 and Figure 6 , further comprising: an impact component slidably disposed on the shell 1, the impact component is used to decompose the impact force received by the energy storage power supply, so as to reduce the magnitude of the force directly acting on the battery pack 2 when the energy storage power supply is impacted, the impact component is arranged around the outer facade of the shell 1, and the straight line where the impact component moves relative to the shell 1 is perpendicular to the shell 1, see Figure 3 The marked coordinate axis in the figure is specifically the Y-axis direction, and the impact-resistance assembly includes: a mounting seat 4 slidably arranged on the housing 1; a connecting frame 5 slidably mounted on the mounting seat 4, and the direction in which the connecting frame 5 moves relative to the mounting seat 4 is consistent with the direction in which the mounting seat 4 moves relative to the housing 1; a roller 6 rotatably mounted on the connecting frame 5; a connecting rod 7 fixedly mounted in the mounting seat 4; two ring columns 8 slidably mounted on the connecting rod 7; a connecting plate 9 rotatably mounted between each of the ring columns 8 and the connecting frame 5; a first spring 10 fixedly mounted between the ring column 8 and the mounting seat 4, and the first spring 10 is sleeved on the connecting rod 7.

[0027] In this embodiment, in order to better show the structure of the energy storage power supply, only two groups of anti-resistance components are set on each side of the energy storage power supply. In actual use, the distribution of the anti-resistance components should be denser than shown in the figure. In this way, no matter from which direction the force acting on the facade of the energy storage power supply will act on one or several groups of anti-resistance components. Figure 3 When the external impact force F acts on the impact component, the force of F is decomposed from the XY direction and is divided into F'1 and F'2, wherein F'1 is dissipated and unloaded under the rolling action of the roller 6, so that the size of F'2 is smaller than the size of F, realizing the decomposition of the first force; secondly, F'2 continues to transmit the force in the impact component through the connecting plate 9, and the force of F'2 is decomposed from the ZY direction and is divided into F"1 and F"2, wherein F"2 is transmitted along the connecting rod 7, acts on the first spring 10 and is absorbed by it, realizing the decomposition of the second force, so, among all the directional forces decomposed by F in the end, only F"1 is directly transmitted to the battery pack 2, and at this time, after the secondary decomposition, its size is much smaller than the size of F. Therefore, the anti-force component can effectively resolve the force and improve the safety of the energy storage power supply; in addition, the force released when the first spring 10 recovers is along the XY axis direction, and the direction is opposite to F"1 and F"2. Therefore, when the first spring 10 recovers, it does not act on the battery pack 2, thereby improving the effect of the anti-force component's decomposition force.

[0028] See also Figure 4 , further comprising: a moving plate 11 slidably mounted in the shell 1; a moving frame 12 fixedly mounted on the moving plate 11, the moving frame 12 being matched with each group of impact components one by one; a convex shaft 13 fixedly mounted on the moving frame 12; a connecting frame 14 fixedly mounted on each of the mounting seats 4, the connecting frame 14 being obliquely arranged, the convex shaft 13 being slidably connected to the connecting frame 14; a limiting shaft 15 fixedly mounted in the shell 1, the limiting shaft 15 being slidably mounted with the mounting seat 4; a second spring 16 fixedly mounted between the mounting seat 4 and the shell 1, the second spring 16 being sleeved on the limiting shaft 15.

[0029] By controlling the movable plate 11 and the movable frame 12 to move upward, the mounting seat 4 will be controlled to move toward the outside of the outer shell 1 through the cooperation of the convex shaft 13 and the connecting frame 14, and the second spring 16 will be deformed. At this time, the impact assembly will be moved out of the outer shell 1 and unfolded, thereby protecting the energy storage power supply. Conversely, when the energy storage power supply is used in a safe environment, the movable plate 11 and the movable frame 12 are controlled to move downward, so that the impact assembly can be retracted into the outer shell 1. Therefore, the position of the impact assembly will not affect the use of the terminal block 3, thereby improving the comfort of use of the energy storage power supply.

[0030] See also Figure 4-Figure 6 , further comprising: the handle 17 slidably mounted on the top of the shell 1, the handle 17 being fixedly mounted on the movable plate 11; a locking assembly disposed between the movable plate 11 and the shell 1, the locking assembly being used to fix the unfolded state of the anti-resistance assembly for convenient use, the locking assembly comprising: a mounting post 18 fixedly mounted on the handle 17; a notch 19 being provided on the top of the shell 1; a limiting block 20 fixedly mounted in the handle 17; a moving rod 21 slidably mounted in the handle 17 and the mounting post 18, the moving rod 21 being slidably mounted on the limiting block 20, the limiting block 2 0 limits the movement of the moving rod 21; an insert block 22 fixedly installed at the end of the moving rod 21, the insert block 22 is inserted into the notch 19, and the positional relationship between the handle 17 and the housing 1 is fixed; a third spring 23 fixedly installed between the moving rod 21 and the limiting block 20; a limiting rod 24 fixedly installed in the handle 17; a pressing block 25 slidably installed on the limiting rod 24, the pressing block 25 and the moving rod 21 use an inclined surface to make the movement of the pressing block 25 control the movement of the moving rod 21, and the end of the pressing block 25 is arranged outside the handle 17.

[0031] The handle 17 is moved upward, and the movable plate 11 and the movable frame 12 are moved upward to unfold the anti-collision assembly. At the same time, the pressing block 25 is controlled to move into the handle 17, and the pressing block 25 controls the movable rod 21 to move in the direction of the mounting column 18. When the handle 17 moves to the position where the plug block 22 corresponds to the slot 19, the anti-collision assembly has been fully unfolded. At this time, the pressing block 25 is released, and the third spring 23 controls the movable rod 21 to reset, and the plug block 22 is inserted into the slot 19. By fixing the position of the handle 17, the positions of the movable plate 11 and the movable frame 12 are fixed, so as to realize the fixed anti-collision assembly after unfolding. In the process of moving the handle 17, the plug block 22 can also be directly used to cooperate with the inclined surface of the shell 1, so that the plug block 22 directly passes over the shell 1 and is inserted into the slot 19.

[0032] On the contrary, when it is necessary to retract the impact assembly, the pressing block 25 is controlled again to retract the moving rod 21 and the insert block 22 into the mounting column 18 to unlock the impact assembly, and then the handle 17 can be controlled to move the moving plate 11 and the moving frame 12 downward.

[0033] See also Figure 1 , Figure 7 and Figure 8, further comprising: an upper base 26 fixedly mounted on the bottom of the housing 1; a lower base 27 slidably and rotatably mounted on the lower part of the upper base 26, the lower base 27 being in contact with the ground; an annular groove 28 being arranged in the lower base 27; a fixed disk 29 fixedly mounted in the upper base 26; a roller foot 30 slidably mounted at the bottom of the fixed disk 29, the roller foot 30 being arranged in the groove 28 and in rolling contact with the lower base 27; a fourth spring 31 fixedly mounted between the fixed disk 29 and the roller foot 30; and a first torsion spring 32 fixedly mounted between the upper base 26 and the lower base 27.

[0034] When the energy storage power supply is subjected to a force in the Z-axis direction, the distance between the upper base 26 and the lower base 27 is reduced, and the fourth spring 31 can buffer the force.

[0035] Since the rotation speed of the roller 6 is limited, when F'1 is eliminated by the roller 6, F'1 will cause the upper base 26 and the lower base 27 to rotate relative to each other. The first torsion spring 32 can store and release the force, thereby assisting the roller 6 in eliminating F'1, further improving the effect of the roller 6 in eliminating F'1, and further improving the safety of the energy storage power supply. The setting of the roller foot 30 makes it possible for the energy storage power supply to be in a complex force environment, and when the fourth spring 31 and the first torsion spring 32 are both acting, they do not affect each other.

[0036] See also Figure 1 , Fig. 9 , Fig.10 and Fig.11 , and also includes: a supporting foot 33 slidably mounted on the lower base 27, wherein the supporting foot 33 slides and expands to increase the contact area between the lower base 27 and the ground; a rack 34 slidably mounted in the lower base 27, wherein the rack 34 is fixedly mounted on the supporting foot 33; a cross rod 35 fixedly mounted in the lower base 27; a top column 36 slidably mounted on the lower base 27, wherein the top column 36 is cross-matched with the cross rod 35; a thread 37 provided on the top column 36; a sleeve 38 rotatably mounted on the lower base 27, wherein the sleeve 38 and the top column 36 are matched through the thread 37, wherein the top column 36 moves to control the rotation of the sleeve 38; a gear 39 fixedly mounted on the sleeve 38, wherein the gear 39 is meshed with the rack 34; a second torsion spring 40 fixedly mounted between the sleeve 38 and the lower base 27, wherein the second torsion spring 40 is sleeved on the sleeve 38.

[0037] In the natural state, the bottom surface of the top column 36 is lower than the bottom surface of the lower base 27. Therefore, when the energy storage power supply is placed on the ground, the top column 36 is controlled to move upward relative to the lower base 27, and the top column 36 rotates the sleeve 38 through the thread 37, the second torsion spring 40 is twisted, and the sleeve 38 rotates the gear 39 to move the rack 34, thereby realizing the expansion of the supporting foot 33. In this way, by increasing the contact area between the lower base 27 and the ground, the energy storage power supply can be placed more stably and the anti-falling ability of the energy storage power supply is improved; conversely, after picking up the energy storage power supply, the second torsion spring 40 reverses the sleeve 38, controls the support foot 33 to retract, and controls the top column 36 downward, thereby reducing the control occupied by the energy storage power supply and facilitating storage and transportation.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
