Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, and more specifically to a portable battery energy storage device. Background Technology

[0002] Portable energy storage batteries are a common energy supply device in outdoor life. They mainly consist of a battery pack, a protective casing, a charging port mechanism, a carrying device, and a solar panel charging device. The operation process of a portable energy storage battery is as follows: when in use, the operator pulls the carrying device to move the entire portable energy storage battery to a designated outdoor location. At the same time, the operator can insert the charging device into the charging port mechanism to charge the battery. When the weather is sunny, the operator can connect an external solar panel to recharge the portable energy storage battery.

[0003] Chinese invention patent CN116365074B discloses a household battery energy storage system, including an energy storage component. The energy storage component includes an energy storage box, with solar panel slots on both the front and back. A handle slot is located inside and at the top of the solar panel slot. A gear slot is located at the top of the handle slot, and a trapezoidal sub-block is fixedly connected to the bottom of the gear slot inside the handle slot. A support slot is located at the bottom of the solar panel slot. Transmission slots are located on both sides of the gear slot, and support side toothed slots are located on both sides of the support slot. A control cavity is located at the top of the support side toothed slot. This invention, by providing a lifting handle, facilitates easy movement by allowing the handle to be moved upwards as a carrying handle. It also allows the user to selectively activate the solar panel unfolding program when the lifting handle is raised, and to orient it to any angle.

[0004] It is evident that current portable solar energy storage devices still have solar panels mounted on the outer surface, which inevitably leads to wear and tear on the solar panel surface during movement. At the same time, they cannot effectively absorb vibrations, making the energy storage device relatively weak in shock resistance. In addition, existing energy storage devices cannot achieve good waterproofing, and when used outdoors, unexpected rainfall can easily cause short circuits, leading to device failure and low stability.

[0005] Power outage protection, waterproof, automatic angle adjustment, shock absorption, and protection for the solar panels during movement. Summary of the Invention

A circular groove is provided on the side of the support plate near the connecting components. When charging using solar energy, the circular groove is fixed to an auxiliary rod. The extension plate includes a reversible straight plate and a second connecting block. The extension plate is hinged to the upper and lower sides of the solar panel frame, and the second connecting block is installed on the upper and lower sides of the stabilizing ribs.

[0009] Furthermore, the connecting assembly includes a connecting cover plate, the front of which has multiple connecting ports, and a waterproof component is installed inside the connecting ports. A display screen is installed on the top of the connecting ports on the front of the connecting cover plate. An auxiliary long rod is fixedly connected to the top of the connecting cover plate. Edge connecting grooves are formed around the connecting cover plate. The connecting assembly is fixedly connected to the outer shell assembly by bolts installed in the edge connecting grooves.

[0010] Furthermore, the fixing component includes a snap-fit ​​rod, with a rotating locking block fixedly connected to the outer side of the snap-fit ​​rod. The snap-fit ​​rod has a cavity inside, and a central rod is installed inside the cavity. A movable star rod is installed on the outer side of the central rod. The movable star rod consists of a star rod ring, a central connecting rod, and a star rod locking block. A first spring is installed on the outer side of the snap-fit ​​rod at the top of the star rod ring, and a second spring is installed on the central rod at the bottom of the star rod ring. The rotating locking block is fixed inside the first, second, and third locking slots in different states.

[0011] Furthermore, an inclined block is fixedly connected inside the snap-fit ​​rod on the outer side of the middle rod.

[0012] Furthermore, the waterproof component includes two first main rods, each with a water-repellent plate installed on its inner side. The two water-repellent plates seal the connection port, forming a water-repellent space. Cams are fixedly connected to the upper and lower ends of the first main rods.

[0018] 1. This invention, by incorporating a solar panel frame and a shock-absorbing component, facilitates the reversal of the solar panel frame's unfolding and installation process after use, allowing the extended panels to be stored inside the solar panel frame. In this case, all unfolded solar panels are stored inside, preventing scratches and collisions during transportation.

[0019] 2. By providing a fixing component, the present invention facilitates the fixing of the component inside the second connecting block. The central rod position increases the outer surface diameter of the star rod block, making it better fixed inside the second connecting block and preventing movement during use.

[0020] 3. By incorporating a waterproof component, this invention facilitates the sealing of the connection socket by a water-proof plate after the electrical port is unplugged. This prevents rainwater from seeping into the connection socket during heavy rain. Simultaneously, the reverse movement of the rotating bracket disconnects the electrical connection block from the power supply mechanism of the connection socket, thus providing short-circuit protection for the energy storage device. This ensures that the energy storage device will not experience a short circuit even if it is completely submerged in water. Furthermore, it can still be used normally after being removed and dried, enhancing the stability and safety of the energy storage device's power supply. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The portable battery energy storage device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 3This invention provides a portable battery energy storage device, including a housing assembly 1. The housing assembly 1 includes a battery housing 101, with a battery slot 102 inside the battery housing 101. A handle slot 103 is formed on the top of the battery housing 101, and a carrying rack 6 is installed inside the handle slot 103. A semi-circular groove is formed on the top of the battery housing 101 inside the handle slot 103, allowing the user to remove the carrying rack 6 through the semi-circular groove during short-distance travel. Placement slots are formed on both sides of the battery housing 101, with a solar panel holder 3 installed on the outer side of the placement slots. Extension plates 4 are installed on the upper and lower sides of the solar panel holder 3, and a fixing assembly 5 is installed inside the solar panel holder 3. Multiple shock-absorbing grooves 104 are formed inside the placement slots, and shock-absorbing components are installed inside the shock-absorbing grooves 104. 8. The battery casing 101 has multiple upper fixing blocks 105 fixedly connected to the top and bottom of the placement groove on its side. The number of upper fixing blocks 105 is the same as that of the shock-absorbing groove 104. A spiral rod 106 is installed inside the handle groove 103. A horizontal moving block 107 is installed on the outside of the spiral rod 106. The horizontal moving block 107 is composed of a slider and a locking rod. A small motor is installed inside the battery casing 101 at one end of the spiral rod 106. When the locking rod is pulled out, the slider slides on the surface of the spiral rod 106. When the locking rod is pressed, the slider cooperates with the spiral rod 106. The rotation of the motor drives the slider to move, thereby controlling the tilt angle of the solar panel frame 3. A connecting component 2 is installed on the front of the battery casing 101. A waterproof ring 7 is installed between the casing component 1 and the connecting component 2.

[0032] In this embodiment, it should be specifically noted that: a battery is installed inside the battery slot 102, and the battery is connected to the electrical connection block 907 by an electrical connection. The connection method is existing technology and will not be described in detail here.

[0033] The main difference between this embodiment and the prior art is that in this embodiment, the extensibility of the extension plate 4 and the fixing function of the fixing component 5 are used to protect the solar panel frame 3 and the outer surface of the solar panel of the extension plate 4. At the same time, the shock-absorbing component 8 is used to achieve protection during transportation, thus achieving a better shock absorption effect. Specifically, the components are: solar panel frame 3, extension plate 4, fixing component 5, and shock-absorbing component 8.

[0034] The above structure is the main structure of this embodiment. It solves the problem that the surface of portable solar panels is easily scratched during transportation, leading to product defects and that they cannot be effectively protected during transportation. Secondly, the waterproof component 9 is used to achieve waterproofing and automatic power-off, which achieves a better water discharge effect for the energy storage device and avoids short circuits when exposed to water. The small motor is an existing structure, and the specific structure and connection method of the small motor will not be described in detail in this embodiment.

[0035] Referring to the connecting assembly 2, the portable frame 6 includes a handle frame 601. The bottom of the handle frame 601 has a sliding groove 602. A connecting block is installed inside the sliding groove 602. A guide support rod 603 is hinged to the bottom of the connecting block. The other end of the guide support rod 603 is hinged to the top of the horizontal moving block 107. When the small motor rotates, the rotation of the screw rod 106 causes the horizontal moving block 107 to change the tilt angle of the handle frame 601, thereby achieving angle adjustment.

[0036] In this embodiment, it should be specifically noted that the opening of the slide groove 602 enables the guide support rod 603, the spiral rod 106 and the horizontal moving block 107 to be stored in the horizontal state, forming a relatively neat upper surface. At the same time, it also provides sliding space for the connecting block, so that the angle adjustment range of the solar panel frame 3 can be changed when the connecting block is adjusted in the interior of the slide groove 602.

[0037] Reference Figure 3 The connecting component 2 includes a connecting cover plate 201. The front of the connecting cover plate 201 has multiple connecting ports 202. A waterproof component 9 is installed inside the connecting ports 202. A display screen 203 is installed on the top of the connecting ports 202 on the front of the connecting cover plate 201. An auxiliary long rod 204 is fixedly connected to the top of the connecting cover plate 201. Edge connecting grooves 205 are formed around the connecting cover plate 201. The connecting component 2 is fixedly connected to the outer shell component 1 by bolts installed in the edge connecting grooves 205. A waterproof ring 7 is installed between the outer shell component 1 and the connecting component 2. The protruding structure of the connecting component 2 and the waterproof ring 7 combine to form a waterproof effect on the inside of the outer shell component 1.

[0038] In this embodiment, it should be specifically noted that the auxiliary rod 204 supports the circular groove 307 during use, so that the circular groove 307 rotates outside the auxiliary rod 204 when the angle is adjusted, thus preventing it from sliding outward and falling off.

[0039] Reference Figure 4The solar panel frame 3 includes a support plate 301. Two bracket plates 302 are mounted on the back of the support plate 301, and the bracket plates 302 are hinged to the back of the support plate 301. Two stabilizing ribs 303 are fixedly connected to the back of the support plate 301. A fixing component 5 is installed inside each stabilizing rib 303. A first slot 304, a second slot 305, and a third slot 306 are provided on both sides of each stabilizing rib 303. The first slot 304 is used to store and fix the rotating block 502 in an unused state. The second slot 305 is used to store and fix the rotating block 502 when connected to the upper fixing block 105. The third slot 306 is used to store and fix the rotating block 502 when connected to the second connecting block 402. The support plate 301... A solar panel is installed on the front of the 1. A circular groove 307 is provided on the side of the support plate 301 near the connecting component 2. When charging with solar energy, the circular groove 307 is fixed on the auxiliary long rod 204. The extension plate 4 includes a reversing straight plate 401 and a second connecting block 402. The extension plate 4 is hinged to the upper and lower sides of the solar panel frame 3. The second connecting block 402 is installed on the upper and lower sides of the stabilizing rib plate 303. When unfolding, the solar panel frame 3 and the extension plate 4 are taken out from the side of the battery shell 101 as a whole. The extension plate 4 is rotated half a turn along the edge of the solar panel frame 3 and installed on the upper and lower sides of the solar panel frame 3. The fixing component 5 is fixed inside the second connecting block 402. The rotating block 502 is installed inside the first slot 304.

[0040] In this embodiment, it should be specifically explained that: when adjusting the angle, the handle 601 slides on the support plate 302 to change the angle. After use, the solar panel frame 3 is operated in reverse according to the above unfolding and installation process so that the extension plate 4 is stored inside the solar panel frame 3, which can protect the solar panel and avoid scratches and collisions during transportation. At the same time, the second connecting block 402 is installed inside the shock absorption groove 104, so that when vibration occurs, the third spring 802 can effectively reduce the vibration effect.

[0041] Reference Figure 5-6The fixing component 5 includes a snap-fit ​​rod 501, with a rotating snap-fit ​​block 502 fixedly connected to the outer side of the snap-fit ​​rod 501. The snap-fit ​​rod 501 has a cavity inside, with a central rod installed inside the cavity. A movable star rod 503 is installed on the outer side of the central rod. The movable star rod 503 consists of a star rod ring 5031, a central connecting rod 5032, and a star rod snap-fit ​​block 5033. A first spring 504 is installed on the outer side of the snap-fit ​​rod 501 at the top of the star rod ring 5031, and a second spring 505 is installed on the central rod at the bottom of the star rod ring 5031. The rotating snap-fit ​​block 502 is fixed inside the first slot 304, the second slot 305, and the third slot 306 in different states, respectively. It is fixed by the action of the first spring 504 and will not move when fixed.

[0042] In this embodiment, it should be specifically noted that when the locking rod 501 is fixed to the second connecting block 402, the excessive compression of the first spring 504 causes the star rod ring 5031 to produce a relative displacement. Under the reverse force of the first spring 504, it moves downward relative to the star rod locking block 5033. This process causes the star rod locking block 5033 to move outward under the action of the inclined block, thereby achieving a better fixing effect within the second connecting block 402.

[0043] Reference Figure 7 The shock absorption component 8 includes a shock absorption ramp 801 and a third spring 802. The shock absorption ramp 801 is installed inside the battery compartment 102. When encountering vibration, the shock absorption component 8 applies a buffering force to the extension plate 4 and the solar panel frame 3. The third spring 802 reduces the vibration effect, thus achieving a shock absorption protection effect. At the same time, the fixing component 5 and the shock absorption component 8 are fixed to prevent the solar panel frame 3 from moving during the movement.

[0044] In this embodiment, it should be specifically explained that: the top of the damping inclined block 801 is provided with an inclined surface, so that when the second connecting block 402 enters the damping groove 104, the edge of the second connecting block 402 first contacts the inclined surface, and then the damping inclined block 801 moves downward with subsequent pressure. After it is fully inserted, the upper surface of the damping inclined block 801 applies pressure to the second connecting block 402. When vibration occurs, the upper and lower damping inclined blocks 801 apply a buffering force to the second connecting block 402, thereby reducing the vibration effect.

[0045] Reference Figure 8The waterproof component 9 includes two first main rods 901, each with a water-repellent plate 902 installed on its inner side. The two water-repellent plates 902 seal the connection port 202, forming a water-repellent space. Cams 903 are fixedly connected to the upper and lower ends of the first main rods 901. Reciprocating rods 904 are installed on both sides of the connection port 202 on the back of the cams 903. A fourth spring 905 is installed on the outer side of the reciprocating rods 904. A rotating bracket 906 and an electrical connection block 907 are installed on the back of the connection port 202. 06 is installed on both sides of the electrical connection block 907. The front of the electrical connection block 907 is powered by a contact metal plate, and the back of the electrical connection block 907 is powered by a copper wire stable power supply. The power supply mechanism is installed inside the connection socket 202. When the rotating bracket 906 rotates and moves the electrical connection block 907 to the front, the power supply mechanism inside the connection socket 202 contacts the metal plate of the electrical connection block 907 to achieve normal power supply. When the electrical connection block 907 moves to the back, the electrical connection block 907 is energized and the metal plate is disconnected, causing the power supply mechanism to be de-energized, thus achieving power failure protection.

[0046] In this embodiment, it should be specifically noted that: torsion springs are installed on the outer sides of both the rotating bracket 906 and the first main rod 901. After the electrical port is pulled out, the torsion springs simultaneously apply a reverse force to reseal the water-proof plate 902 at the entrance of the connection socket 202, so that the energy storage device will not allow rainwater to penetrate into the interior of the connection socket 202 even in heavy rain. The reverse movement of the rotating bracket 906 causes the electrical connection block 907 to disconnect from the power supply mechanism of the connection socket 202. At this time, the energy storage device achieves short circuit protection, so that the energy storage device will not experience a short circuit even if it is completely submerged in water.

[0047] Working principle of the invention:

[0048] The main problem solved by this embodiment is to protect the solar panels on the outer surface of the solar panel frame 3 and the extension plate 4 by utilizing the extensibility of the extension plate 4 and the fixing function of the fixing component 5. At the same time, the shock-absorbing component 8 is used to protect the solar panels during transportation, achieving a better shock absorption effect. This solves the problem that the surface of portable solar panels is easily scratched during transportation, leading to product defects and the inability to effectively protect them during transportation. Furthermore, the waterproof component 9 is used to seal the panels, achieving waterproofing and automatic power-off, thus achieving a better water discharge effect for the energy storage device and avoiding short circuits when exposed to water.

[0049] The specific steps are as follows:

[0050] With a short movement, the portable holder 6 is lifted upward from the semi-circular groove inside the handle slot 103. At this time, the two portable holders 6 form a double handle state with their tops in contact. The user can then use the portable holders 6 to move the energy storage device to the location where it is needed.

[0051] In the charging state, the rotating block 502 is rotated half a turn to remove it from the inside of the second slot 305. Then, the solar panel frame 3 and the extension plate 4 are removed from the side of the battery casing 101 as a whole. The extension plate 4 is rotated half a turn along the edge of the solar panel frame 3 and installed on the upper and lower sides of the solar panel frame 3. Then, the fixing component 5 is fixed inside the second connecting block 402. At this time, the rotating block 502 is installed inside the first slot 304. During this process, since the first spring 504 is installed inside the stabilizing rib 303, when the fixing component 5 rises, the star rod ring 5031 compresses the first spring 504. At this time, the star rod ring 5031 is subjected to the reverse force of the first spring 504 and moves downward relative to it. Since the middle rod is located inside the star rod block 5033 and is fixedly connected to the inclined block, the inclined block applies outward pressure to the star rod block 5033, causing the outer surface diameter of the star rod block 5033 to increase. Larger, better fixed inside the second connecting block 402 to prevent movement during use. After the extension plate 4 is assembled, the circular groove 307 is placed on the auxiliary long rod 204. Under the action of gravity, the bottom of the solar panel frame 3 is fixed. The support plate 302 is unfolded, and the handle 601 is taken out. The handle 601 is installed on the support plate 302 at the bottom of the solar panel frame 3 to support the solar panel frame 3. After the handle 601 is taken out to support the solar panel frame 3, the locking rod on the horizontal moving block 107 is pressed to lock the horizontal moving block 107 on the spiral rod 106. At this time, the horizontal moving block 107 cannot slide freely on the spiral rod 106. Then, the small motor at one end of the spiral rod 106 is started. The motor drives the spiral rod 106 to rotate, so that the spiral rod 106 drives the horizontal moving block 107 to rotate, thereby realizing the angle adjustment between the handle 601 and the solar panel frame 3.

[0052] After long-distance transport and use, reverse the unfolding and installation process of the solar panel frame 3 to retract the extension plate 4 inside the solar panel frame 3. This ensures that all unfolded solar panels are retracted, preventing scratches and collisions during transport. Then, install the solar panel frame 3 on the side of the battery casing 101. At this point, the second connecting block 402 enters the shock-absorbing groove 104, pressing the shock-absorbing inclined block 801 inward, causing the third spring 802 to contract downward. The clamping action of the shock-absorbing inclined block 801 stabilizes the solar panel frame 3, ensuring stability. When encountering vibration, the shock-absorbing component 8 applies a buffering force to the extension plate 4 and the solar panel frame 3, and the third spring 802 reduces the vibration effect, thus achieving a shock-absorbing protection effect. After the second connecting block 402 is installed into the shock-absorbing groove 104, the rotating block 502 in the third slot 306 is taken out and fixed inside the second slot 305. At this time, the fixing component 5 extends out of the stabilizing rib 303 and is fixed inside the upper fixing block 105, so that the solar panel frame 3 is fixed under the action of the fixing component 5 and the shock-absorbing component 8, preventing it from moving during the movement.

[0053] When connecting an appliance, the appliance's wiring port is inserted into the connection socket 202, pushing the water-proof plate 902 to rotate to both sides. The rotation of the water-proof plate 902 drives the first main rod 901 to drive the cam 903 to push the reciprocating rod 904 to move inward. The reciprocating rod 904 pushes the outer side of the rotating bracket 906 to move backward, and the inner side of the rotating bracket 906 to move forward. The two ends inside the electrical connection block 907 connect with the front wiring, realizing power supply to the connection socket 202. At this time, the appliance's wiring port can charge normally after entering the connection socket 202. After unplugging the appliance, the first main rod 901... 01 and the torsion spring installed on the outside of the rotating bracket 906 simultaneously apply a reverse force to reseal the entrance of the connection socket 202 with the water-proof plate 902, so that rainwater will not penetrate into the interior of the connection socket 202 even in heavy rain. The reverse movement of the rotating bracket 906 disconnects the power supply mechanism of the electrical connection block 907 from the connection socket 202. At this time, the energy storage device achieves short circuit protection, so that the energy storage device will not short circuit even if it is completely submerged in water. After it is taken out and dried, it can still be used normally, which enhances the stability and safety of the power supply of the energy storage device.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
