Description

Technical Field

[0001] This invention relates to the field of micro-miniature thermal battery activation technology, specifically to a micro-miniature thermal battery activation device. Background Technology

[0002] Currently, power supply solutions for emergency equipment such as aircraft black boxes mainly rely on batteries, fuel cells, and thermal batteries. However, fuel cells are limited by the complexity of fuel storage and supply systems and have extremely high requirements for the sealing and temperature stability of the working environment, making them difficult to adapt to the miniaturization and extreme environment requirements of emergency equipment. Thermal batteries, on the other hand, have become the preferred power source for high-end emergency equipment such as aircraft black boxes due to their significant advantages such as fast activation speed, high specific energy, long storage life, and strong adaptability to extreme environments.

[0003] Existing micro-miniature thermal battery activation devices, especially those adapted to emergency equipment with extremely high requirements for reliability, stability, and long-term storage, employ a single triggering mechanism. Relying on electrically driven active triggering, the device cannot respond promptly to power system failures, leading to thermal battery activation failure. The lack of multiple passive triggering methods results in low adaptability to complex environments and hinders the ability to re-trigger the device after active triggering failure, increasing the risk of activation failure. Furthermore, existing thermal battery springs, constantly under stress, are prone to accidental energy release during transportation and storage due to minor vibrations, collisions, or temperature fluctuations. This can cause premature activation. Long-term stress on the springs can lead to fatigue and elasticity decay, resulting in insufficient ejection force during triggering, failing to push the firing pin to effectively strike the ignition cap and affecting activation success rate. Furthermore, spring aging and failure can cause unexpected rebound, leading to false triggering, premature activation of the thermal battery, wasted energy, and even equipment damage.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a micro-miniature thermal battery activation device to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a micro-sized thermal battery activation device, comprising a battery substrate, a mounting base fixedly connected to the top of the battery substrate, a filler installed at the bottom of the mounting base, a plurality of ignition caps fitted between the filler and the bottom of the mounting base, a circular seat fixed inside the mounting base, a plurality of striking pins vertically slidingly installed in the circular holes on the surface of the circular seat via elastic elements, and pressure plates one, two, and three arranged sequentially from bottom to top above the circular seat, pressure plates one and two abutting against the upper sections of the striking pins through two symmetrical small holes, and the bottom of pressure plate three abutting against the tops of the two symmetrical striking pins, wedges fixed on the protrusions on the surfaces of pressure plates one and two and on the surface of pressure plate three, push rods abutting against the outer sides of the wedges, an outer box sleeved on the outer end of the push rod, the outer box being fixed to the battery substrate and the mounting base, a power storage component being provided inside the outer box, and a triggering component being connected inside the outer box through the power storage component.

The number of wedges corresponds to the number of outer boxes and push rods. The wedges are set with an inclined surface on top, and the inclined surface of the wedges is used for the push rod to move against the surface.

[0009] Preferably, the upper end of the firing pin is a stepped column structure, the two symmetrical firing pins abut against the top of the pressure plate three, the symmetrical small holes on the surface of the pressure plate two abut against the first layer of stepped structure above the two firing pins at the corresponding positions, the symmetrical small holes on the surface of the pressure plate one abut against the second layer of stepped structure of the two firing pins at the corresponding positions, and the pressure plate one, pressure plate two, and pressure plate three abut against the multiple firing pins in a two- or two-dimensional staggered manner.

[0010] Preferably, the power storage component includes a limiting block, and three sets of the outer box are arranged on the outside of the battery base. The number of power storage components corresponds to the number of wedges. The limiting blocks are slidably installed in the inner cavity of the three sets of the outer box through flexible metal sheets. The outer end of the limiting block is slidably connected to a push block, and the inner side of the limiting block is limited and locked with a spring. The outer end of the spring is connected to the push block.

[0011] Preferably, the three energy storage components are respectively connected to the first trigger component, the second trigger component, and the third trigger component.

[0012] Preferably, the first triggering component includes electromagnet one and electromagnet two, which are arranged opposite to each other in one of the outer boxes. Electromagnet one is fixed inside the outer end of one of the outer boxes, and electromagnet two is fixed on the push block. When electromagnet one and electromagnet two are energized, their magnetic forces repel each other. Electromagnet one and electromagnet two are used to adjust the position of the push block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention features three triggering components, which are activated under different conditions. Each triggering component is equipped with a set of pressure plates. Pressure plates one, two, and three correspond to each triggering component. The three sets of triggering components are electromagnetic energization triggering, high temperature triggering, and high pressure triggering, respectively. After a triggering component is activated, it presses down on the corresponding pressure plate. Each pressure plate is connected to two sets of striking pins. When the pressure plate is pressed down, the striking pins strike the ignition cap to ignite it. This allows the battery substrate to be activated multiple times under different conditions, avoiding activation failure. Even if the device fails to activate electromagnetic energization, it can still be activated again by striking the ignition cap under complex environmental conditions such as high temperature and high pressure through the other two sets of triggering components, improving the success rate of activating such thermal batteries in complex environments.

[0018] 2. This invention includes a power storage component, comprising three sets of components, each corresponding to a triggering component. The triggering components store power in the springs within the power storage component. In the initial, untriggered state, the springs remain in a naturally extended, uncharged state, preventing stress fatigue caused by long-term power storage. This effectively protects the structural integrity and elastic properties of the springs, significantly extending their service life and facilitating long-term storage. Furthermore, it prevents elastic failure or attenuation due to long-term stress, ensuring sufficient elastic potential energy is stably accumulated upon triggering. This guarantees the ejection force of the subsequent push rod, thereby ensuring the impact force of the firing pin striking the ignition cap and ensuring stable and effective ignition activation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 11 This invention provides a technical solution: a micro-sized thermal battery activation device, comprising a battery substrate 1, a mounting base 2 fixedly connected to the top of the battery substrate 1, a filler 3 installed at the bottom of the mounting base 2, and multiple ignition caps 31 fitted between the filler 3 and the bottom of the mounting base 2. An annular seat 4 is fixed inside the mounting base 2, and multiple striking pins 41 are vertically slidably mounted in the circular holes on the surface of the annular seat 4 via elastic elements. Above the annular seat 4, from bottom to top, are arranged a pressure plate 5, a pressure plate 6, and a pressure plate 7. Pressure plate 5 and pressure plate 6 each abut against the upper part of the striking pins 41 through two symmetrical small holes. The upper end of the striking pins 41 has a stepped column structure. The two symmetrical striking pins 41 abut against the top of the pressure plate 7. The symmetrical small holes on the surface of pressure plate 6 abut against the first layer of stepped structure above the two striking pins 41 at corresponding positions. The symmetrical small holes on the surface of pressure plate 5 abut against the second layer of stepped structure above the two striking pins 41 at corresponding positions. The pressure plates 5, 6, and 7 are in contact with each other and the multiple impact pins 41 in a staggered two-way direction. The bottom of the pressure plate 7 is in contact with the top of the two symmetrical impact pins 41. Wedges 8 are fixed on the protrusions on the surfaces of the pressure plates 5 and 6 and on the surface of the pressure plate 7. Push rods 10 are connected to the outside of the wedges 8. The protrusion on the top of the pressure plate 5 corresponds to the notch on one side of the pressure plates 6 and 7. The protrusion on the top of the pressure plate 26 corresponds to the notch on the other side of the pressure plate 7. When the pressure plates 5, 6, and 7 are overlapping, the wedges 8 are located at the same horizontal position and are distributed at equal angles. The number of wedges 8 corresponds to the number of outer boxes 9 and push rods 10. The top of the wedges 8 is set with an inclined surface, which is used for the contact movement of the push rods 10.

[0034] The outer end of the push rod 10 is fitted with an outer box 9, which is fixed on the battery base 1 and the mounting base 2. The outer box 9 is equipped with a power storage component, which includes a limiting block 111. Three sets of the outer box 9 are arranged on the outside of the battery base 1. The number of power storage components corresponds to the number of wedges 8. The limiting blocks 111 are slidably installed in the inner cavity of the three sets of outer boxes 9 through flexible metal sheets. The outer end of the limiting block 111 is slidably connected to a push block 112. The inner side of the limiting block 111 is limited and locked with a spring 113. The outer end of the spring 113 is connected to the push block 112. The outer box 9 is connected to a trigger component through the power storage component. The three power storage components are respectively connected to the first trigger component, the second trigger component, and the third trigger component.

[0035] Multiple triggering is achieved through multiple sets of outer boxes 9. Specifically, three sets of outer boxes 9 with identical structures are set up. Each set of outer boxes 9 is equipped with a spring 113, a limit block 111, and a push block 112. Each set of outer boxes 9 is also equipped with an independent push rod 10 to correspond to different triggering methods. When a power system fails due to extreme accidents or other special circumstances, the first triggering component cannot achieve active triggering. At this time, the device can achieve passive triggering under high-temperature conditions through the second triggering component. When the ambient temperature rises, the second triggering component is passively activated under high-temperature conditions. Similarly, under high-voltage conditions, the third triggering component achieves passive triggering. The three sets of triggering components correspond to pressure plate one 5, pressure plate two 6, and pressure plate three 7, respectively. Under different triggering conditions, the corresponding pressure plates are different, thus ensuring that the striker 4 can still be activated under different conditions. Activation is achieved by impacting the ignition cap 31. Positioning holes adapted to the two sets of strikers 41 are provided on the surface of the first pressure plate 5. The upper end of the striker 41 forms a contact fit with the first pressure plate 5 through the positioning holes. After the wedge block 8 is contacted, the first pressure plate 5 moves downward with the buffer and guiding effect of the elastic connection structure. Pressure is applied to the striker 41 through the positioning holes, causing the two sets of strikers 41 to strike the corresponding ignition cap 31 below. At the same time, the second pressure plate 6 is also provided with symmetrical holes that are offset from the symmetrical holes on the surface of the first pressure plate 5, corresponding to the other two sets of strikers 41. The second pressure plate 6 contacts the strikers 41 to achieve the impact of the ignition cap 31. The third pressure plate 7 is connected to the top of the remaining two sets of strikers 41. The third pressure plate 7 carries the corresponding two sets of strikers 41 to strike the ignition cap 31, realizing the triggering under different conditions and completing the activation of the battery substrate 1.

[0036] Example 2

[0037] Based on Example 1, please refer to Figures 1 to 11The first triggering component includes electromagnet 121 and electromagnet 122, which are arranged opposite each other inside one of the outer boxes 9. Electromagnet 121 is fixed inside the outer end of one of the outer boxes 9, and electromagnet 122 is fixed on the push block 112. When electromagnets 121 and 122 are energized, their magnetic forces repel each other. Electromagnets 121 and 122 are used to adjust the position of push block 112. The second triggering component includes a wedge 131, which is installed in a recessed cavity inside the outer box 9. A thermostatic spring 132 is fastened to the inclined surface of the wedge 131 by screws. The thermostatic spring 132 is connected to one of the power storage components. The push block 112 in the middle abuts against each other, and the temperature difference spring 132 is used to adjust the position of the push block 112. The third triggering component includes a piston chamber 141, which is installed inside the outer end of one of the outer boxes 9. A piston block 143 is slidably and sealed at one end of the piston chamber 141. One side of the piston block 143 abuts against the push block 112, and a piston block 142 is slidably and sealed at the other side of the piston block 143. A connecting pipe 144 is sleeved and fixed at the outer end of the piston chamber 141. Air is provided in the cavity between the piston block 143 and the piston block 142. The position of the push block 112 is adjusted by external pressure between the piston block 143 and the piston block 142.

[0038] The control circuit supplies power to the energizing element of the first triggering component. After power is applied, electromagnet 121 and electromagnet 122 in the component synchronously generate magnetic fields. Utilizing the physical principle of like poles repelling each other, electromagnet 122 is displaced under the repulsive force, thereby pushing the push block 112, which is adapted to it, to move linearly along the inner cavity guide structure of the outer box 9. During the movement of the push block 112, its end contacts and continuously compresses the spring 113, causing the spring 113 to undergo elastic deformation and accumulate elastic potential energy. At the same time, the push block 112 forms a sliding fit with the inclined structure of the limiting block 111 and the connected flexible metal sheet, pushing the two sets of symmetrically arranged limiting blocks 111 outwards. The push rod moves until the limit block 111 separates. When the limit block 111 separates, the communication channel between the inner cavity of the outer box 9 and the push rod 10 is fully opened. At this time, the spring 113, which has accumulated elastic potential energy, quickly and elastically resets. The resulting ejection force drives the push rod 10 to quickly extend into the interior of the mounting base 2 along the guide channel. The end of the push rod 10 precisely abuts against the inclined surface of the wedge block 8 on the pressure plate 3 7. Since the pressure plate 3 7 is movably connected to the mounting base 2 through the elastic connector and its bottom is fixedly connected to the two sets of firing pins 41, after the wedge block 8 is resisted by the push rod 10, the force is converted into a vertical downward pressure through the inclined surface guide. This drives the pressure plate 3 7 to move downward synchronously with the two sets of firing pins 41, striking the ignition cap 31 located directly below it, thus completing the active activation trigger.

[0039] When a power system fails due to extreme accidents or other special circumstances, the electromagnets 121 and 122 of the first triggering component cannot be powered and cannot be actively triggered. At this time, the device can be passively triggered in a high-temperature environment through the second triggering component. When the ambient temperature rises, the thermal difference spring 132 in the second triggering component undergoes directional deformation due to the thermal expansion difference of the material. This deformation displacement pushes the corresponding push block 112 to move along the inner cavity of the outer box 9. During this process, the push block 112 simultaneously squeezes the spring 113 and completes elastic storage. At the same time, it pushes the limiting block 111 to move to both sides to release the limitation on the spring 113. After the limitation is released, the ejection force of the spring 113 drives the corresponding push rod 10 to extend into the mounting base 2. The end of the push rod 10 abuts against the wedge block 8 on the pressure plate 5, causing the pressure plate 5 to move downward and apply pressure to the striker 41 through the positioning hole, causing the two sets of strikers 41 to strike the corresponding ignition cap 31 below them, thus achieving activation in a high-temperature environment.

[0040] For high-pressure environments, a third triggering component enables another passive triggering mechanism. One set of outer casings 9 is connected to the external environment of the device housing the thermal battery via a sealed connecting pipe 144. The interior of the connecting pipe 144 forms a sealed piston chamber 141. A piston block 142 is slidably disposed within the piston chamber 141, and a second piston block 143 is connected to a pusher block 112 within the outer casing 9. When the external environmental pressure reaches a preset threshold, the connecting pipe 144 acts on the piston block 142, pushing it to move along the piston chamber 141, thereby compressing the piston. The air in cavity 141 causes pressure to be transmitted to piston block 143 and drives it to move. Piston block 143 drives the corresponding push block 112 to move along the inner cavity of outer box 9. Push spring 113 completes elastic storage and pushes open limit block 111. Then spring 113 ejects and drives push rod 10 to extend into the mounting base 2 and abut against wedge block 8 on pressure plate 6. With the help of the same triggering process, pressure plate 6 is pushed to move downward and abut against and drive the corresponding two sets of firing pins 41 to strike the ignition cap 31 below through the positioning holes on its surface, so as to be activated under high pressure.

[0041] Working principle: When using this miniature thermal battery activation device, firstly, according to the operating system of the thermal battery installation equipment, the first trigger component is energized by controlling the energizing element. After energization, electromagnet 121 and electromagnet 222 generate magnetic force. Utilizing the principle of like poles repulsion, electromagnet 222 pushes push block 112 to move under the repulsive magnetic force. When push block 112 moves, it pushes spring 113, compressing spring 113 to achieve elastic storage, and also setting the limit block... 111 is pushed open to both sides. When the limiting block 111 is pushed open, the position where the inner cavity of the outer box 9 is connected to the push rod 10 is opened. At this time, the stored spring 113 ejects and pushes the push rod 10 into the mounting base 2. The push rod 10 will abut against the wedge block 8 on the pressure plate 3 7. The pressure plate 3 7 is connected to two sets of firing pins 41. After the wedge block 8 is abutted, it cooperates with the elastic connection of the firing pins 41 to make the pressure plate 3 7 press down, and take the two sets of firing pins 41 connected to strike the ignition cap 31 at the corresponding position below.

[0042] Based on the above, since the outer box 9 is provided in three sets, each of the three sets of outer boxes 9 is equipped with a spring 113, a limiting block 111, and a push block 112, and each set of outer boxes 9 has a corresponding push rod 10, when a special situation occurs and the power start fails, electromagnet one 121 and electromagnet two 122 cannot be actively triggered in time. Under high temperature conditions, the second triggering component achieves passive triggering. Under high temperature conditions, the temperature difference spring 132 deforms, and the deformed temperature difference spring 132 pushes the push block 112 to move. When the push block 112 pushed by the second triggering component moves, it will also push the spring 113. The spring 113 is compressed to achieve elastic storage, pushing the limiting block 111 to both sides. When the limiting block 111 is pushed open, the connection between the inner cavity of the outer box 9 and the push rod 10 is opened. At this time, the stored spring 113 ejects and pushes the push rod 10 into the mounting base 2. The push rod 10 will abut against the wedge 8 on the pressure plate 5. The small hole on the surface of the pressure plate 5 abuts against two sets of firing pins 41. After the wedge 8 is abutted, it cooperates with the elastic connection of the firing pins 41 to make the pressure plate 5 press down. The pressure plate 5 abuts against the firing pins 41 through the small hole, so that the firing pins 41 strike the ignition cap 31 at the corresponding position below.

[0043] Based on the above, under high pressure, the third triggering component will be passively triggered. The outer end of another set of outer boxes 9 extends to the outside of the installation equipment through connecting pipe 144. The high pressure will push piston block 142 to move. The movement of piston block 142 will push the air in piston chamber 141, and the increased pressure will push piston block 2 143 to move. Piston block 2 143 is connected to push block 112. When push block 112 is pushed by the third triggering component, it will push spring 113. Spring 113 is compressed to achieve elastic storage, pushing limit block 111 towards When the two sides are pushed open, the position where the inner cavity of the outer box 9 connects with the push rod 10 is opened. At this time, the stored spring 113 ejects and pushes the push rod 10 into the mounting base 2. The push rod 10 will abut against the wedge 8 on the pressure plate 2 6. The small hole on the surface of the pressure plate 2 6 abuts against two sets of firing pins 41. After the wedge 8 is abutted, it cooperates with the elastic connection of the firing pins 41 to make the pressure plate 2 6 press down. The pressure plate 2 6 also abuts against the firing pins 41 through the sleeve of the small hole, so that the firing pins 41 strike the ignition cap 31 at the corresponding position below.

[0044] Finally, when the ignition cap 31 is impacted, the initiating agent inside the ignition cap 31 ignites first after being impacted, providing an initial flame for subsequent ignition, which in turn ignites the ignition material inside the battery substrate 1, and is heated by the heating element. When the electrolyte is heated above its melting point and melts into a liquid state, the positive and negative ions inside can move freely, forming an ion conduction pathway, and the electrochemical reaction of the positive and negative electrodes of the battery proceeds smoothly, outputting electrical energy to the outside.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
