Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to a handle and an energy storage device. Background Technology

[0002] With the continuous development of battery technology and the increasing market demand, the capacity, weight, and size of energy storage devices (such as battery packs and energy storage cabinets) in energy storage systems are gradually increasing. This change makes the installation and handling of energy storage devices (such as battery packs and energy storage cabinets) increasingly complex, especially in large-scale energy storage applications, such as industrial and commercial energy storage power stations, where traditional handling methods face more and more challenges and difficulties. Traditional handling methods mainly rely on the lifting holes on the casing of energy storage devices (such as battery packs and energy storage cabinets) to achieve handling using lifting equipment. While this method is suitable for large energy storage devices (such as battery packs and energy storage cabinets), it often lacks stable leverage points when handling small energy storage devices (such as battery packs and energy storage cabinets), leading to difficulties in handling.

[0003] To address this issue, existing technologies employ handles on energy storage devices (such as battery packs and energy storage cabinets) to assist in handling. By adding handles, operators can more easily move these devices, especially smaller ones, providing a more stable point of leverage. However, existing handle designs typically connect to the energy storage device (such as a battery pack or energy storage cabinet) via an operating hole. During handling, the connection between the operating hole and the handle may loosen or become unstable, affecting not only the smoothness of the handling but also potentially damaging the equipment, increasing the risks and inconvenience during transport.

[0004] Therefore, existing technologies urgently need a more robust and efficient handling solution for energy storage devices (such as battery packs and energy storage cabinets) to improve safety and efficiency during the handling process. Utility Model Content

[0005] In order to improve the installation stability between the handle and the energy storage device (such as a battery pack, energy storage cabinet, etc.) and to improve the safety and efficiency of handling the energy storage device (such as a battery pack, energy storage cabinet, etc.), this application provides a handle and an energy storage device.

[0006] The handle and energy storage device provided in this application adopt the following technical solution:

[0007] A handle, comprising:

[0008] The locking hole provided on the handle includes an operating hole and a limiting hole that are interconnected.

[0009] An anti-detachment component is movable on the handle, the anti-detachment component having a locked position and a released position; in the locked position, the anti-detachment component can at least partially cover the operating hole and limit the limiting hole; in the released position, the operating hole is open.

[0010] By adopting the above technical solution and utilizing the design of the locking hole and anti-detachment component, operators can complete the installation and disassembly without complicated steps. This simplified operation makes handling work more intuitive and convenient, reduces assembly and disassembly time, reduces the risk of operational errors, and improves work efficiency. The cooperative design of the operating hole and limit hole of the locking hole can quickly fix the handle, avoiding the cumbersome installation steps in traditional handling methods and improving handling efficiency. The anti-detachment component design ensures that the locking hole and connector are not easy to fall off, thereby ensuring reliable installation of the handle and improving safety and stability during handling. This design has strong versatility and is suitable for various equipment and handling scenarios. Its reliable structure and simple operation enable this design to provide effective handling solutions in different fields and applications.

[0011] In one specific implementation, the handle has a protrusion and the anti-slip component has a through hole; in the released position, the protrusion and the through hole are engaged.

[0012] By adopting the above technical solution, the connection between the paddle and the handle is more reliable through the insertion and cooperation of the convex bulge and the through hole, ensuring that the paddle will not cover the opening of the operating hole, so that the operating hole can always be used normally, thereby facilitating the implementation of subsequent disassembly and assembly work.

[0013] In one specific implementation, the handle is provided with a first reinforcing rib distributed around the locking hole.

[0014] By adopting the above technical solution, the bending resistance of the locking hole can be improved by distributing the first reinforcing rib around the locking hole. When subjected to external load or impact, the stress generated by the lateral force can be effectively dispersed, preventing the area of ​​the locking hole from being damaged or deformed due to bending.

[0015] In one specific implementation, when in the locked position, the anti-disengagement component is abutted and fixed to the first reinforcing rib.

[0016] By adopting the above technical solution, the contact between the paddle and the first reinforcing rib provides a physical limit, ensuring that the paddle cannot move further when locked, thereby ensuring the stability of the paddle in the locked position, preventing the paddle from loosening, shifting or misoperating during use, and enhancing the reliability of the entire locking mechanism.

[0017] In one specific implementation, the handle is provided with a second reinforcing rib distributed along its outer peripheral edge.

[0018] By adopting the above technical solution, the design of the second reinforcing rib can improve the strength of the handle when subjected to external force, and prevent the handle from bending, breaking or other damage. When the user grips, pulls or pushes the handle, the design of the second reinforcing rib can disperse the external force, so that the shape of the handle will not be deformed or damaged due to excessive concentration of a single force point, thereby improving the stability and durability of use.

[0019] In one specific implementation, the opening size of the operating hole is larger than the opening size of the limiting hole.

[0020] By adopting the above technical solution, the size difference between the operating hole and the limiting hole can ensure that the components are properly matched and remain stable during the installation process; the larger operating hole facilitates installation, while the smaller limiting hole restricts movement and achieves limiting during installation, further enhancing the stability and safety of the overall assembly.

[0021] In one specific implementation, the handle is provided with a gripping portion having a wavy gripping surface extending along its length.

[0022] By adopting the above technical solution and the ergonomic wave-shaped design, the hand and handle fit together more closely, reducing hand fatigue and discomfort caused by prolonged use. This design can distribute grip pressure and maintain greater comfort during operation. In addition, the wave-shaped grip surface provides stronger friction upon contact, increasing anti-slip properties and ensuring safety and stability during operation.

[0023] An energy storage device includes a housing, an energy storage element disposed inside the housing, and a handle as described in any of the preceding claims; the handle is detachably mounted on the housing via a connector.

[0024] In one specific implementation, the connector includes a head, a shoulder, and a connecting portion. The connecting portion is detachably connected to the housing. The locking hole of the handle is fitted onto the shoulder, and the head forms a limiting fit with the outer wall of the locking hole.

[0025] By adopting the above technical solution and through the design of the handle and connector, the installation process of energy storage devices (such as battery packs and energy storage cabinets) is simplified, making the installation process simple and efficient, reducing time and labor costs. The fit between the connector and the energy storage device (such as battery packs and energy storage cabinets) ensures the stability and convenience of the installation process. The insertion fit between the shoulder and the limiting hole ensures a stable connection between the connector and the handle, thereby ensuring a stable installation between the handle and the energy storage device (such as battery packs and energy storage cabinets), avoiding loosening or misalignment due to vibration or external force, and improving the overall stability of the energy storage device (such as battery packs and energy storage cabinets). The limiting fit between the connector head and the outer wall of the limiting hole further enhances the stability after installation, ensuring a firm connection between the handle and the energy storage device (such as battery packs and energy storage cabinets), and preventing the handle and connector from slipping or being accidentally loosened.

[0026] In one specific implementation, the diameter of the head is greater than the opening size of the limiting hole and less than or equal to the opening size of the operating hole, and the diameter of the shoulder is adapted to the opening size of the limiting hole.

[0027] By adopting the above technical solution, the diameter of the shoulder is matched with the opening size of the limiting hole, ensuring a stable contact between the shoulder and the limiting hole, guaranteeing the stability and reliability of the handle during use, and preventing loosening due to vibration or external force; the size of the head is larger than the size of the limiting hole, ensuring that the head is stably abutted against the outer wall of the limiting hole, preventing the handle from falling off during use, improving overall safety, and making energy storage devices (such as battery packs, energy storage cabinets, etc.) more reliable during handling and use.

[0028] In summary, the beneficial technical effects of this application are as follows: By designing the fit between the handle and the connector, this application simplifies the installation and disassembly process, improving handling efficiency and safety; the handle, through the design of locking holes, including operating holes and limiting holes, achieves a quick and stable connection; the anti-detachment component further enhances the stability of the connection, preventing the handle from loosening or falling off during handling, ensuring the safety and stability of the equipment; in addition, the addition of reinforcing ribs and a wave-shaped grip surface improves the durability and comfort of the handle, making operation more convenient, reducing the risks caused by improper operation or external vibration, and optimizing the user experience;

[0029] The installation design of energy storage equipment has also been simplified. The detachable connection between the connector and the energy storage equipment ensures stability, and the fit between the shaft shoulder and the limiting hole ensures a reliable connection between the handle and the energy storage equipment (such as battery packs, energy storage cabinets, etc.). The overall design improves assembly efficiency and reduces labor costs while ensuring the firmness of the connection, avoiding loosening caused by vibration or external force, thereby improving the reliability of the equipment and the safety during use. The simple installation structure, low cost, and intuitive operation make the product highly competitive in the market. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0041] Reference Figure 1 and Figure 2 This application discloses a handle, including two locking holes 2 provided on the handle 1. The two locking holes 2 are symmetrically arranged on the handle 1, and each locking hole 2 includes an operating hole 21 and a limiting hole 22 that are interconnected.

[0042] It also includes an anti-slip component 3 provided on the handle 1. In this embodiment, the anti-slip component 3 includes, but is not limited to, a set, which is provided in correspondence with one of the locking holes 2. In other embodiments, the anti-slip component 3 can also be provided in two sets, which are provided in correspondence with two locking holes 2.

[0043] The anti-detachment component 3 has a locked position and a released position; in the locked position, the anti-detachment component 3 can at least partially cover the operating hole 21 and limit the limiting hole 22; in the released position, the operating hole 21 is fully open;

[0044] In this embodiment, the handle 1 includes, but is not limited to, being made of a strong and durable material, such as metal materials like steel or aluminum alloy, with sufficient strength to withstand external loads and impacts during equipment handling.

[0045] In practical use, the design of the locking hole 2 and the anti-detachment component 3 allows operators to complete the installation and disassembly without complicated steps. This simplified operation makes the handling work more intuitive and convenient, reduces disassembly and assembly time, reduces the risk of operational errors, and improves work efficiency. The cooperative design of the operating hole 21 and the limiting hole 22 of the locking hole 2 can quickly fix the handle 1, avoiding the cumbersome installation steps in traditional handling methods and improving handling efficiency. The design of the anti-detachment component 3 ensures that the locking hole 2 and the connector 9 are not easy to fall off, thereby ensuring the reliable installation of the handle 1 and improving the safety and stability during the handling process. This design has strong versatility and is suitable for various equipment and handling scenarios. Its reliable structure and simple operation make this design able to provide effective handling solutions in different fields and applications.

[0046] Reference Figure 1 and Figure 2 The locking hole 2 includes, but is not limited to, an inverted gourd-shaped hole. The opening size of the upper operating hole 21 is larger than the opening size of the lower limiting hole 22. Through the size difference between the operating hole 21 and the limiting hole 22, it is possible to ensure that each component fits correctly and remains stable during installation. The larger size of the operating hole 21 facilitates installation, while the smaller size of the limiting hole 22 enables limiting during installation, forming a stable locking state, thereby ensuring installation stability and further enhancing the stability and safety of the overall assembly.

[0047] Reference Figure 3The anti-detachment component 3 can be, but is not limited to, a lever 31. The lever 31 is rotatably mounted on the handle 1 by means of a rivet 32. The lever 31 has a locked position and a released position. The operator can achieve the locking and releasing functions by rotating the lever 31. When the lever 31 is in the released position, the opening of the operating hole 21 is fully open, and the handle 1 can be installed. When the lever 31 is rotated to the locked position, the lever 31 at least partially covers the opening of the operating hole 21, thereby limiting the limit hole 22.

[0048] Reference Figure 1-3 To further ensure the stability of the lever 31 when locked, the lever 31 is provided with a through hole 33, which is engaged with the protrusion 4 on the handle 1 to ensure that the lever 31 can be firmly fixed in the locked position and will not be displaced due to external force. This design makes locking and releasing the lever 31 easier, and the operator can complete the connection and disassembly of the device without complicated steps.

[0049] To enhance the structural strength of the handle 1 and prevent damage caused by external impact or load, a first reinforcing rib 5 and a second reinforcing rib 6 are distributed around the handle 1. The first reinforcing rib 5 is distributed around the locking hole 2. In this embodiment, the first reinforcing rib 5 is distributed along both sides of the locking hole 2 and forms a "V" shape. This effectively improves the bending resistance of the locking hole 2 and effectively disperses the stress generated by the lateral force when subjected to external load or impact, preventing the area of ​​the locking hole 2 from being damaged or deformed due to bending. Furthermore, it can also improve the structural stability of the entire handle 1. Under the action of external force, the locking hole 2 can maintain its shape and avoid cracking or loosening, thereby extending its service life.

[0050] In this embodiment, when the paddle 31 is in the locked position, the paddle 31 abuts and is fixed to the first reinforcing rib 5. Specifically, when the paddle 31 is rotated to the locked position, its edge or part of its structure will contact the corresponding position of the first reinforcing rib 5 to form a firm abutment fit, thereby preventing the paddle 31 from moving accidentally and ensuring that it remains stable during operation.

[0051] The second reinforcing rib 6 is distributed on the outer periphery of the handle 1 and extends continuously along the outer periphery of the handle 1. The second reinforcing rib 6 can improve the overall strength of the handle 1 and prevent the handle 1 from bending or breaking during gripping and pulling. The reinforcement of the overall structure not only extends the service life of the handle 1, but also improves its stability and durability.

[0052] In this embodiment, the handle 1 is provided with a gripping part 7. In this embodiment, the gripping part 7 includes, but is not limited to, manual handling, and can also be used for hoisting and handling by hoisting equipment. Hoisting and handling can be achieved by attaching a hoisting rope to the gripping part 7 and then connecting the hoisting rope to the hoisting equipment.

[0053] The grip 7 has a wavy grip surface extending along its length. The wavy grip surface is ergonomically designed so that the hand fits the handle 1 more closely, reducing hand fatigue and discomfort caused by prolonged use. This design can distribute grip pressure, allowing the user to maintain greater comfort during operation. In addition, the wavy grip surface provides stronger friction upon contact, increasing anti-slip properties and ensuring safety and stability during operation.

[0054] Reference Figure 4-8 This application also discloses an energy storage device, which includes, but is not limited to, various forms of battery storage systems such as small household battery packs, large commercial battery packs, energy storage cabinets, and energy storage containers.

[0055] The energy storage device includes a housing 8 and an energy storage element disposed inside the housing 8. In this embodiment, the energy storage element includes, but is not limited to, a battery cell or a battery cell module. The energy storage device also includes a handle 1 as described above, which is detachably mounted on the housing 8 via a connector 9.

[0056] In this embodiment, the housing 8 of the energy storage device is provided with handles 1 and connectors 9 on both sides. Two connectors 9 are installed on each side, and the connectors 9 are provided in a one-to-one correspondence with the locking holes 2 of the handles 1.

[0057] In this embodiment, by setting a handle 1 on the energy storage device, for small battery packs, the handle 1 can be used to provide a hand gripping point for manual handling of the energy storage device; for large battery packs, energy storage cabinets, etc., the handle 1 can also be used to provide a hoisting point, by attaching a hoisting rope to the handle 1 for hoisting equipment to lift and move the energy storage device.

[0058] Reference Figure 5 and Figure 9 The connector 9 includes a head 91, a shoulder 92, and a connecting part 93. In this embodiment, the head 91 is provided with a disassembly hole 95. The connector 9 is fixed to the housing 8 of the energy storage device through the connecting part 93. In this embodiment, the connecting part 93 includes, but is not limited to, a threaded connection with the housing 8. By inserting a tool into the disassembly hole 95 and rotating the entire connector 9, the connecting part 93 is threadedly connected and fixed to the mounting hole on the housing 8, ensuring that the connector 9 is securely connected to the housing 8. In other embodiments, the connecting part 93 and the housing 8 can also be connected by welding or other detachable connection methods.

[0059] The locking hole 2 of the handle 1 is fitted onto the connector 9. This mating structure enables an effective connection between the handle 1 and the housing 8 of the energy storage device. The shoulder 92 can enter the limiting hole 22 through the operating hole 21 and abut against the limiting hole 22. At the same time, the head 91 forms a limiting fit with the outer wall of the limiting hole 22, ensuring the stability and safety of the handle 1 during use, thereby enabling the stable installation of the handle 1 on the energy storage device.

[0060] Reference Figure 9 Furthermore, a stepped limiting surface 94 is formed between the head 91 of the connector 9 and the shoulder 92. This stepped limiting surface 94 is in close contact with the outer wall of the limiting hole 22, thereby further improving the fixing effect between the connector 9 and the handle 1, preventing the handle 1 from becoming loose due to vibration or external force during transportation, thus ensuring the stability and reliability of the connection between the energy storage device and the handle 1.

[0061] In this embodiment, the diameters of the head 91, shoulder 92, and connecting part 93 of the connector 9 decrease sequentially. Furthermore, the diameter of the head 91 of the connector 9 is greater than the opening size of the limiting hole 22 and less than or equal to the opening size of the operating hole 21, while the diameter of the shoulder 92 is adapted to the opening size of the limiting hole 22.

[0062] During this process, since the dimensions of the head 91, the shoulder 92, and the connecting part 93 are all smaller than the dimensions of the operating hole 21 of the locking hole 2, the connecting part 9 can pass smoothly through the operating hole 21 of the locking hole 2 on the handle 1, so that the handle 1 can be fitted onto the connecting part 9, ensuring that the handle 1 can be smoothly installed on the housing 8 of the energy storage device.

[0063] The diameter of the shoulder 92 is matched with the opening size of the limiting hole 22, which ensures a stable abutment between the shoulder 92 and the limiting hole 22, guaranteeing the stability and reliability of the handle 1 during use and preventing loosening due to vibration or external force. The size of the head 91 is larger than the size of the limiting hole 22, ensuring that the head 91 abuts stably against the outer wall of the limiting hole 22, so that the handle 1 is stably connected to the connector 9, thereby ensuring the stable installation of the handle 1 on the energy storage device, preventing the handle 1 from falling off during use, improving overall safety, and making the energy storage device more reliable during handling and use.

[0064] The implementation principle of this application embodiment is as follows: Before installation, rotate the lever 31 on the handle 1 to the release position, and insert the through hole 33 on the lever 31 into the protrusion 4 on the handle 1. The protrusion 4 matches the through hole 33 in shape, so that the lever 31 and the handle 1 form a reliable connection, so that the opening of the operation hole 21 always remains unobstructed, which facilitates subsequent disassembly and assembly work.

[0065] During installation, first, the connector 9 is fixed to the housing 8 of the energy storage device via the connector 93. The connector 93 is screwed into the mounting hole on the housing 8 and threaded to it, thus completing the installation of the connector 9 and the housing 8 of the energy storage device. Then, the handle 1 is placed in the installation position of the housing 8 of the energy storage device. Through the operating hole 21 of the locking hole 2, the handle 1 is fitted onto the connector 9. The connector 9 passes through the operating hole 21, thus pre-installing the handle 1 on the housing 8 of the energy storage device. At this time, the shoulder 92 of the connector 9 is located inside the operating hole 21.

[0066] After pre-installation, lift handle 1 again, so that the shoulder 92 of connector 9 enters the limiting hole 22 through the operating hole 21 of locking hole 2. When the shoulder 92 enters the limiting hole 22, it will form a tight fit with the inner wall of the limiting hole 22. At the same time, the head 91 of connector 9 forms a limiting fit with the outer wall of the limiting hole 22, ensuring that handle 1 is firmly fixed on the equipment.

[0067] Rotate the lever 31 again to lock it into the locked position. The lever 31 abuts against the first reinforcing rib 5 around the locking hole 2 and is fixed. At this time, the lever 31 at least partially covers the opening of the operating hole 21, thereby ensuring a stable connection between the connector 9 and the locking hole 2 and preventing the handle 1 from accidentally falling off during transportation. After installation, the equipment can be transported by manually gripping the gripping part 7 on the handle 1. Alternatively, a hoisting rope can be tied to the handle 1 and connected to the hoisting equipment for lifting and transporting the energy storage equipment.

[0068] The handle 1 of this application has a highly versatile design and operation method, and can be widely applied to energy storage devices and handling scenarios of different sizes and weights, meeting a variety of needs; whether it is a small battery pack or a large battery pack, this design can be used for handling, providing a flexible and effective solution.

[0069] The energy storage device (such as a battery pack or energy storage cabinet) of this application adopts an innovative handle 1 and connector 9 design, which significantly improves the installation and use efficiency of the energy storage device and simplifies the entire installation process. This design securely fixes the connector 9 to the housing 8 of the energy storage device through a detachable connection, and utilizes the locking hole 2 of the handle 1 and the cooperation of the connector 9 to achieve a tight connection between the handle 1 and the housing 8 of the energy storage device. The fit between the shoulder 92 of the connector 9 and the limiting hole 22 ensures the stability of the handle 1 during use and avoids loosening caused by vibration or external force, thereby enhancing overall safety. At the same time, the head 91 of the connector 9 forms a limiting fit with the outer wall of the limiting hole 22, ensuring that the handle 1 is not easy to fall off and improving the reliability of the energy storage device during handling.

[0070] Furthermore, the optimized design of the anti-detachment component 3 further enhances the fixing effect between the connector 9 and the handle 1, ensuring the safety of the equipment during handling and reducing the risk caused by improper connection or detachment. The energy storage equipment (such as battery packs, energy storage cabinets, etc.) of this application, through the structural design of the connector 9 and the handle 1, makes the installation operation simpler and more efficient, significantly reducing installation time and labor costs. This technical solution not only improves the stability of energy storage equipment (such as battery packs, energy storage cabinets, etc.) during use, but also simplifies disassembly and reinstallation operations, thereby enhancing the market competitiveness of the product.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
