Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically to a quick docking structure for a portable new energy storage device. Background Technology

[0002] With the development of renewable energy technologies, new energy storage devices play a vital role in the utilization of renewable energy sources such as solar and wind power, emergency backup power, and outdoor power supply. These devices primarily use lithium batteries (lithium iron phosphate and ternary lithium) or lead-acid batteries as the energy storage medium, and through power conversion and management systems, they achieve the storage, output, and dispatch of electrical energy. Compared to traditional fuel generators, new energy storage devices offer advantages such as environmental friendliness, high efficiency, and low noise, and are widely used in various scenarios including home energy storage, industrial energy storage, and mobile power supplies.

[0003] Currently, new energy storage devices on the market typically include battery modules, inverters, charge and discharge management systems, and interface systems. They connect with other devices through different mechanical connection methods. In existing technologies, the connection methods for energy storage devices mainly include the following: First, plug-in interfaces, which complete the power connection by manually inserting the connector, suitable for portable energy storage devices; second, bolt-fixed connections, which are usually used in industrial-grade high-power energy storage devices, and improve connection stability by tightening bolts; and third, sliding rail docking, which is used in modular energy storage systems, enabling multiple battery units to be quickly expanded. However, these traditional connection methods still have certain limitations in actual use.

[0004] In existing technologies, the connection of energy storage devices often requires manual operation. Although plug-in connections are convenient, they are prone to loosening and poor contact in high-power applications, affecting the stability of power supply. Therefore, this utility model proposes a portable new energy storage device quick docking structure to solve the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a quick docking structure for portable new energy storage devices, which solves the problem that plug-in connections in the prior art are prone to loosening and poor contact in high-power applications, thus affecting the stability of power supply.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A portable new energy storage device quick docking structure includes an energy storage battery block. A handle is rotatably connected to the rear side of the energy storage battery block. A connection socket and a connection port are respectively provided on the front side of the energy storage battery block. A convex shell is fixed to the front side of the energy storage battery block. Two fixing bolts are threaded to both the left and right sides of the convex shell. Fixing mechanisms are provided on both the left and right sides inside the convex shell. A protective mechanism is provided on the front side of the convex shell.

[0008] The fixing mechanism includes a pressing rod, which is slidably connected inside the convex shell. A crossbar is fixed to one end of the pressing rod near the convex shell. Rotating rods are rotatably connected to both sides of the crossbar. A sliding block is rotatably connected to the section of the rotating rod away from the crossbar. A moving rod is fixedly connected to the bottom of the sliding block. Multiple connecting rods evenly distributed vertically are slidably connected inside the moving rod. A concave block is fixedly connected to the end of the connecting rod away from the moving rod. Wedge blocks are fixed to both the front and rear sides of the sliding block. Wedge grooves are formed on both the front and rear sides of the interior of the convex shell. A buffer assembly is provided at the end of the connecting rod away from the concave block. A spring is fixed to the middle of the side of the crossbar away from the pressing rod. A positioning plate is fixed to the end of the spring away from the crossbar.

[0009] The protective mechanism includes a receiving block, which is fixed to the front side of the convex shell. A rotating shaft is rotatably connected inside the receiving block. A protective plate is fixed to the outer periphery of one end of the rotating shaft. A transmission assembly is provided inside the convex shell.

[0010] The buffer assembly includes a damping rod, which is fixed to the end of the connecting rod away from the concave block. Slider blocks are fixed on both the front and rear sides of the outer periphery of the end of the connecting rod near the moving rod. Sliding grooves are opened on both the front and rear sides of the interior of the moving rod.

[0011] The transmission assembly includes a movable plate that is slidably connected inside the convex shell. A connecting rod is fixed to the bottom of the movable plate, and a connecting rod is fixed to the end of the connecting rod away from the movable plate. A rack is fixed to the front side of the connecting rod, and a gear is rotatably connected inside the receiving block. The rack meshes with the gear.

[0012] The wedge block is slidably connected inside the wedge groove, and the positioning plate is fixed inside the convex shell;

[0013] The end of the damping rod away from the connecting rod is fixed inside the moving rod, and the two sliders are slidably connected inside the two grooves respectively;

[0014] The end of the movable plate away from the connecting rod is fixed to the outer periphery of the pressing rod, and the rack is slidably connected to the inside of the convex shell;

[0015] The gear is fixed to the outer periphery of the end of the rotating shaft away from the protective plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model achieves rapid docking and stable fixation of energy storage equipment through the cooperation between the fixing mechanism and the buffer component. When the pressing rod moves, it can drive the crossbar to move, so that the sliding block and the connecting rod can quickly lock the docking port. At the same time, the damping rod of the buffer component provides a buffering effect, reduces mechanical impact force, and avoids damage to the equipment due to vibration or impact during docking. It effectively solves the problem of unstable connection under traditional docking methods and improves the stability and service life of docking.

[0018] 2. This utility model achieves the protection function of the equipment interface through the cooperation between the protective mechanism and the transmission component. When the device is not connected, the protective plate covers the connection port, effectively preventing dust and foreign objects from entering the port. When the device needs to be connected, the transmission component drives the protective plate to open automatically, exposing the connection port and completing the connection. This effectively solves the problem that the interface of the energy storage device is easily contaminated and damaged in the outdoor environment, and improves the protective performance and service life of the device.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-3 As shown, this utility model is a portable new energy storage device quick docking structure, including a storage battery block 1, a handle 2 rotatably connected to the rear side of the storage battery block 1, a connection socket 9 and a connection port 10 respectively provided on the front side of the storage battery block 1, a convex shell 3 fixed on the front side of the storage battery block 1, two fixing bolts 8 threadedly connected to the left and right sides of the convex shell 3, a fixing mechanism 4 provided on the left and right sides of the interior of the convex shell 3, and a protective mechanism 7 provided on the front side of the convex shell 3.

[0031] Specifically, the energy storage battery block 1 is a new energy storage device, composed of a lithium battery pack, an inverter, and an aluminum alloy shell. It is a mature existing technology with the function of storing electrical energy. It is mainly used to power electronic devices and household appliances. The handle 2 is located on the rear side of the energy storage battery block 1. By holding the handle 2, it is convenient to carry and move the energy storage battery block 1. The connection socket 9 and the connection port 10 are used to connect to the device to be powered, so that the energy storage battery block 1 can be connected to different devices to power different devices. The convex shell 3 is used to protect the connection socket 9 and the connection port 10, so that the device to be powered can be protected from damage by external factors when connected to the energy storage battery block 1. The fixing bolt 8 is used to connect the convex shell 3 to the energy storage battery block 1.

[0032] Please see Figure 4-5 As shown, the fixing mechanism 4 includes a pressing rod 401, which is slidably connected inside the convex shell 3. A crossbar 402 is fixed to one end of the pressing rod 401 near the convex shell 3. Rotating rods 403 are rotatably connected to both the left and right sides of the crossbar 402. A sliding block 404 is rotatably connected to the end of the rotating rod 403 away from the crossbar 402. A moving rod 405 is fixedly connected to the bottom of the sliding block 404. Multiple connecting rods 406, which are evenly distributed vertically, are slidably connected inside the moving rod 405. The connecting rods 406 are located away from the moving rod. One end of 405 is fixedly connected to a concave block 407. Both the front and rear sides of the sliding block 404 are fixed with wedge blocks 408. Both the front and rear sides of the interior of the convex shell 3 are provided with wedge grooves 409. The wedge blocks 408 are slidably connected inside the wedge grooves 409. The end of the connecting rod 406 away from the concave block 407 is provided with a buffer assembly 5. The middle of the side of the crossbar 402 away from the pressing rod 401 is fixed with a spring 410. The end of the spring 410 away from the crossbar 402 is fixed with a positioning plate 411. The positioning plate 411 is fixed inside the convex shell 3.

[0033] Specifically, the pressing rod 401 is slidably connected to the top of the convex shell 3 for easy operation. The pressing rod 401 is connected to the crossbar 402. When the pressing rod 401 moves, it drives the crossbar 402 to move. When the crossbar 402 is subjected to force and moves, it also controls the movement of the pressing rod 401 accordingly. The spring 410 is made of 65Mn spring steel and is connected to the crossbar 402. The positioning plate 411 is fixed inside the convex shell 3 to fix the position of the spring 410 and to cooperate with the crossbar 402 to move and compress the spring 410. The rotating rod 403 is rotatably connected to the crossbar 402 and the sliding block 404. When moving, the rotating rod 403 will rotate accordingly, thereby transmitting the rotational motion to the sliding block 404, which in turn causes the sliding block 404 to move. The moving rod 405 is fixedly connected to the sliding block 404. When the sliding block 404 moves, it will drive the moving rod 405 to move together. The wedges 408 on the front and rear sides of the sliding block 404 slide in the wedge grooves 409 respectively to ensure that the sliding block 404 always maintains horizontal movement. The connecting rod 406 is used to connect the moving rod 405 and the concave block 407. The concave block 407 is made of rubber material and is mainly used to fix the position of the connection interface to prevent the connection interface from easily falling off.

[0034] Please see Figure 7 As shown, the protective mechanism 7 includes a receiving block 701, which is fixed to the front side of the convex shell 3. A rotating shaft 702 is rotatably connected inside the receiving block 701. A protective plate 703 is fixed to the outer periphery of one end of the rotating shaft 702. A transmission assembly 6 is provided inside the convex shell 3.

[0035] Specifically, the receiving block 701 is used to accommodate the rotation of the rotating shaft 702. The rotating shaft 702 is connected to the protective plate 703. When the rotating shaft 702 rotates, it will drive the protective plate 703 to rotate together. The protective plate 703 is made of aluminum alloy and is used to protect the connection socket 9 and connection port 10 on the front side of the energy storage battery block 1.

[0036] Please see Figure 6 As shown, the buffer assembly 5 includes a damping rod 501, which is fixed to the end of the connecting rod 406 away from the concave block 407. The end of the damping rod 501 away from the connecting rod 406 is fixed inside the moving rod 405. Slider 502 is fixed on both the front and rear sides of the outer periphery of the end of the connecting rod 406 near the moving rod 405. Slide grooves 503 are provided on both the front and rear sides of the interior of the moving rod 405. The two sliders 502 are slidably connected inside the two slide grooves 503 respectively.

[0037] Specifically, one end of the damping rod 501 is fixed inside the moving rod 405, and the other end is fixed to the connecting rod 406. When the connecting rod 406 moves, the damping rod 501 will be subjected to a force, thereby providing a reaction force to the connecting rod 406. The slider 502 is fixed to the outer periphery of the connecting rod 406 and slides inside the groove 503 to ensure that the connecting rod 406 can maintain horizontal movement.

[0038] Please see Figure 7 As shown, the transmission assembly 6 includes a movable plate 601, which is slidably connected inside the convex shell 3. The end of the movable plate 601 away from the connecting rod 602 is fixed to the outer periphery of the pressing rod 401. The bottom of the movable plate 601 is fixed with the connecting rod 602. The end of the connecting rod 602 away from the movable plate 601 is fixed with a connecting rod 603. The front side of the connecting rod 603 is fixed with a rack 604, which is slidably connected inside the convex shell 3. The inside of the receiving block 701 is rotatably connected with a gear 605, which is fixed to the outer periphery of the end of the rotating shaft 702 away from the protective plate 703. The rack 604 meshes with the gear 605.

[0039] Specifically, the movable plate 601 is fixed to the outer periphery of the pressing rod 401. When the pressing rod 401 moves, it will drive the movable plate 601 to move accordingly. The connecting rod 602 connects the movable plate 601 and the connecting rod 603. When the movable plate 601 moves, it will drive the connecting rod 603 to move. The rack 604 fixed to the front side of the connecting rod 603 meshes with the gear 605. When the connecting rod 603 moves, it will drive the rack 604 to move accordingly. After the rack 604 moves, it will control the gear 605 to rotate. When the rack 604 moves vertically downward, the gear 605 will rotate clockwise. When the rack 604 moves upward, the gear 605 will rotate counterclockwise. Thus, the rotation of the protective plate 703 is synchronously controlled by the movement of the pressing rod 401.

[0040] Working principle: When the energy storage battery block 1 is needed to power the device, first place the device on a flat surface. Then, select the connection socket 9 or connection port 10 according to the device's connection method and connect it to the device's connection cable. After determining the interface, press the corresponding pressing lever 401 on the top of the interface. At this time, the pressing lever 401 will move vertically downward into the convex shell 3. During the movement of the pressing lever 401, because the pressing lever 401 is connected to the crossbar 402, the movement of the pressing lever 401 will drive the crossbar 402 to move together. When the crossbar 402 moves, it will exert a vertical force on the spring 410 at the bottom, thereby causing the pressing lever 401 to contract under force. When the vertical distance between 402 and sliding block 404 changes, it will exert a force on the rotating rod 403 connecting the crossbar 402 and the sliding block 404. When the rotating rod 403 is subjected to the force, it will rotate around the end connected to the crossbar 402, thereby generating a circular motion trajectory at the end connected to the sliding block 404, which will drive the sliding block 404 to move. The wedges 408 on the front and rear sides of the sliding block 404 are slidably connected to the inside of the wedge groove 409, so when the rotating rod 403 rotates, the sliding block 404 will only move horizontally. Then the sliding block 404 will drive the moving rod 405 to move horizontally. At this time, the two moving rods 405 will move in opposite directions.

[0041] Simultaneously, the downward movement of the pressing rod 401 will also cause the movable plate 601 to move vertically downward. When the movable plate 601 moves, the connecting rod 603 connected by the connecting rod 602 will move accordingly with the movable plate 601. At this time, the connecting rod 603 will also drive the rack 604 to move. Since the rack 604 meshes with the gear 605, the gear 605 will rotate accordingly when the rack 604 moves. Since the gear 605 is connected to the rotating shaft 702, when the gear 605 rotates, it will simultaneously drive the rotating shaft 702 to rotate, thereby causing the protective plate 703 to rotate clockwise, thus opening the port. At this time, the connection wire of the device to be powered can be plugged into the energy storage battery block 1 through the port.

[0042] After the connection is completed, release the pressing rod 401. At this time, the spring 410 loses the vertical force of the crossbar 402 and will generate a reset extension movement, that is, generate a vertical upward force on the crossbar 402. At this time, the crossbar 402 moves upward, the rotating rod 403 correspondingly generates a reset rotation, the two moving rods 405 will move towards each other, and the movable plate 601 will also move accordingly with the movement of the pressing rod 401. When the movable plate 601 moves upward, the rack 604 will also move upward in the same way, thereby controlling the gear 605 to rotate, so that the rotating shaft 702 drives the protective plate 703 to rotate counterclockwise, blocking the connection between the equipment to be powered and the port.

[0043] When the two moving rods 405 move towards each other, the two concave blocks 407 will also move towards each other and contact the outer periphery of the connecting wire of the device to be powered, thereby clamping the device to be powered. After the concave blocks 407 contact the connecting interface, a force will be generated, causing the connecting rod 406 to move. The movement of the connecting rod 406 will also generate a force and transmit the force to the damping rod 501. When the connecting rod 406 moves, the slider 502 will also slide synchronously in the slide groove 503. When the damping rod 501 is subjected to a force, a corresponding reaction force will be generated, so that the concave blocks 407 always contact the side of the connecting interface, preventing the connecting interface from easily falling off during connection.

[0044] The above description is merely an example and illustration of the concept of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined in the claims, they should all fall within the protection scope of the present invention.
