Description

Hinge structure, power storage cabinet and power storage device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 8, 2023, with application number 202323363801.8 and invention name “Hinge structure, electricity storage cabinet and electricity storage device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of hinge technology, and more specifically, relates to a hinge structure, a power storage cabinet, and a power storage device. Background Art

[0003] The statements here only provide background information related to the present application and do not necessarily constitute prior art. A hinge generally includes a rotating shaft and two connecting structures connected to the rotating shaft. The two connecting structures are respectively connected to two components to achieve a rotational connection between the two components. For sealed cabinets such as power storage cabinets, switch cabinets, and distribution cabinets that require sealed cabinet doors, sealing strips are installed around the cabinet doors or around the door openings of the cabinet body. The two connecting structures are respectively connected to the cabinet door and the cabinet body. Since the positions of the two connecting structures relative to the rotating shaft are fixed, the sealing strips are squeezed when the cabinet door is opened or closed.

[0004] Application Contents

[0005] The purpose of the embodiments of the present application is to provide a hinge structure, a power storage cabinet and a power storage device to solve the problem in the related art that the two connecting structures of the hinge are fixed relative to the rotating shaft, and when used in a sealed cabinet, the sealing strip will be squeezed when the cabinet door is opened and closed.

[0006] In a first aspect, an embodiment of the present application provides a hinge structure, comprising:

[0007] two connection structures; and,

[0008] A rotating shaft, rotatably connecting the two connection structures;

[0009] At least one connecting structure includes an adjusting mechanism, which includes a first component and a second component. The first component is connected to the rotating shaft, and the second component is movably connected to the first component along an axial direction perpendicular to the rotating shaft.

[0010] In the technical solution of the embodiment of the present application, an adjustment mechanism is used through at least one connecting structure of the hinge structure, and the first component of the adjustment mechanism is movably connected to the second component to realize that the corresponding connecting structure of the hinge structure can be extended and retracted to provide a stroke, so that the position of the second component of the connecting structure and the rotating shaft can be adjusted. Accordingly, when in use, the position of the device connected to the second component relative to the rotating shaft can be adjusted to facilitate the mutual rotation of the two devices connected by the hinge structure; especially when used in a sealed cabinet, before the cabinet door rotates relative to the cabinet body, the cabinet door is moved away from the cabinet body through the adjustment mechanism to reduce the squeezing of the sealing strip.

[0011] In some embodiments, the adjustment mechanism further includes an elastic member, which elastically presses against the first member in a direction away from the second member.

[0012] An elastic member is provided to elastically push the first member away from the second member. After the first member is unlocked, the first member can be elastically pushed away, automatically increasing the gap between the first member and the second member, thereby increasing the adjustment space of the two connection structures.

[0013] In some embodiments, the elastic member is disposed between the first member and the second member, and two ends of the elastic member respectively abut against the first member and the second member.

[0014] The elastic member can be an elastic compression member, and the elastic member is arranged between the first member and the second member to push the first member and the second member away from each other, which also facilitates the installation of the elastic member.

[0015] In some embodiments, the adjustment mechanism further includes a guide rail, which is mounted on the second component, and the first component is slidably mounted on the guide rail.

[0016] The guide rail is provided to guide the first component to move relative to the second component, so that the movement is more stable; and the guide rail can also support the first component to increase the structural strength.

[0017] In some embodiments, the guide rail is cylindrical, and a sliding hole is provided on the first component, and the sliding hole is sleeved on the guide rail.

[0018] The use of cylindrical guide rails has a simple structure, is easy to process and manufacture, and improves processing and assembly accuracy.

[0019] In some embodiments, guide rails are respectively provided at both ends of the second component along the axial direction of the rotating shaft, and sliding holes are respectively provided at both ends of the first component.

[0020] Guide rails are respectively provided at both ends of the second component to support and guide the movement of the first component. The structure is simple and can more stably support the first component, thereby improving the structural strength.

[0021] In some embodiments, the adjustment mechanism further includes a locking structure for locking the relative positions of the first component and the second component.

[0022] The locking structure can fix the positions of the first component and the second component relatively, so that the cabinet door can be conveniently locked on the cabinet body when in use, which is convenient for installation and use.

[0023] In some embodiments, the locking structure includes a screw and a locking nut mounted on the screw, one end of the screw is connected to the second component, the other end of the screw slides through the first component, and the locking nut is arranged on the side of the first component away from the second component.

[0024] By arranging a screw on the second component and passing the screw through the first component, and installing a locking nut on the screw, the locking nut can be moved on the screw to push the first component close to the second component, thereby locking the position of the first component relative to the second component. When in use, since the locking structure can lock the relative position of the first component and the second component, the use of the fastening structure can be reduced when locking the cabinet door to the cabinet body, which facilitates the locking and fixing of the cabinet door.

[0025] In some embodiments, a clamping ring is provided at an end of the screw away from the second component.

[0026] A retaining ring is provided on the screw to reduce the risk of the locking nut falling off when the locking nut is loosened.

[0027] In some embodiments, along the axial direction of the rotating shaft: one side of the middle portion of the first component is connected to the rotating shaft, the other side of the middle portion of the first component is provided with a protrusion, and the second component is provided with a groove for accommodating the protrusion.

[0028] Providing a protrusion on the side of the middle of the first component away from the rotating shaft can increase the structural strength of the first component, and providing a groove on the second component to accommodate the protrusion can reduce the volume of the combination of the first component and the second component, thereby reducing the volume of the hinge structure.

[0029] In some embodiments, the first component includes a threaded rod, and the second component includes a plate. The plate is provided with a through hole, the threaded rod is inserted through the through hole, and a locking nut is installed on the threaded rod.

[0030] The first component uses a threaded rod and the second component uses a plate, which has a simple structure and can further simplify the structure of the hinge structure and reduce costs.

[0031] In a second aspect, an embodiment of the present application provides a power storage cabinet, comprising the hinge structure as described in the above embodiment.

[0032] In some embodiments, the power storage cabinet further includes a cabinet body and a cabinet door, one connecting structure includes an adjustment mechanism, another connecting structure is connected to the cabinet door, and a second component of the adjustment mechanism is connected to the cabinet body.

[0033] A connecting structure is connected to the cabinet body, and the second component of the adjustment mechanism of the other connecting structure is connected to the cabinet body, so that the second component stably supports the first component, and then stably supports the cabinet door, so that the cabinet door can rotate smoothly; the first component can be relatively far away from the second component, so that when the cabinet door is closed, the cabinet door can be made approximately parallel to the surface where the door opening of the cabinet is located, and the squeezing of the sealing strip on the side close to the hinge structure is reduced, which is convenient for closing the cabinet door. Then, the cabinet door is locked on the cabinet body, and the cabinet door can be pressed against the sealing strip more evenly to improve the sealing effect; after the cabinet door is unlocked, the sealing strip will push the cabinet door to move approximately horizontally away from the cabinet body. When the cabinet door is opened, the squeezing of the sealing strip on the side close to the hinge structure can be reduced, which is convenient for opening the cabinet door; since the squeezing of the sealing strip is reduced, the service life of the sealing strip can also be increased.

[0034] In some embodiments, at least one sealing strip may be provided around the periphery of the cabinet door; and / or at least one sealing strip may be provided around the periphery of the door opening of the cabinet body.

[0035] At least one circle of sealing strip is provided around the periphery of the cabinet door and / or the periphery of the door opening, so as to achieve a good sealing effect after the cabinet door is closed.

[0036] In a third aspect, an embodiment of the present application provides an electricity storage device, comprising the hinge structure as described in the above embodiment, or comprising the electricity storage cabinet as described in the above embodiment.

[0060] Currently, with the vigorous development of new energy, the use of new energy power batteries is increasing. New energy batteries, with their outstanding advantages such as high cost-effectiveness, excellent safety, and low pollution, have achieved increasingly widespread application, not only in general electronics but also in the power and energy storage fields. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace, among other fields. As the application areas of power batteries continue to expand, their market demand is also continuously increasing. As a core component of new energy power devices, the safety of power batteries directly affects the safety performance of the power devices.

[0061] A sealed cabinet refers to a cabinet structure in which the cabinet door can be well sealed with the cabinet body.

[0062] A power storage cabinet is a highly concentrated energy storage device that combines multiple batteries or battery cells within a sealed cabinet. When used, it can function as a power battery. Because the battery cells within the cabinet have high voltages and large capacities, thermal runaway can generate large amounts of high-temperature, high-pressure gas. This gas can accumulate within the cabinet and potentially cause an explosion. To address this, power storage cabinets are often filled with nitrogen to mitigate fire safety hazards posed by thermal runaway.

[0063] In the embodiments of the present application, a battery cell is a unit that undergoes electrochemical reactions to store and release electrical energy, and is also the smallest unit of charge and discharge in a battery. Battery cells include, but are not limited to, lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries. The shape of a battery cell includes, but is not limited to, a cylinder, a flat body, a rectangular parallelepiped, or other shapes. Battery cells are generally classified according to the packaging method, including but not limited to: cylindrical battery cells, square battery cells, and soft-pack battery cells.

[0064] The battery mentioned in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack. The battery generally includes a casing for encapsulating one or more battery cells. The casing can, to a certain extent, prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. In some cases, the battery cells can also be used directly, that is, the battery may not include a casing, which is not limited here.

[0065] In a battery, when there are multiple battery cells, they can be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections. Multiple battery cells can be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery cell structure is housed within a housing. Alternatively, a battery can be constructed by first connecting multiple battery cells in series, in parallel, or in a hybrid connection to form a battery module, which is then connected in series, in parallel, or in a hybrid connection to form a single unit, which is then housed within a housing. The battery may also include other structures, such as a busbar assembly for electrically connecting multiple battery cells.

[0066] A hinge generally includes a rotating shaft and two connecting structures connected to the rotating shaft. The two connecting structures are respectively connected to two components to achieve a rotational connection between the two components.

[0067] The structure of a sealed cabinet primarily consists of a cabinet body and a door. The cabinet body is provided with a door opening to allow objects, such as battery cells, to be placed inside the cabinet to form a power storage cabinet. One side of the door is typically hinged to the cabinet body using a hinge, allowing the door to be rotated and easily opened and closed. To effectively seal the door opening and reduce the risk of gas leakage from within the cabinet and external air entering the cabinet, a sealing strip is often installed around the door opening on the cabinet body or around the perimeter of the door. When the door is locked to the cabinet body, it presses against the sealing strip to seal the door opening.

[0068] In order to improve the sealing effect, a sealing strip with a large compression amount is generally provided, and the cabinet door also has a large compression amount on the sealing strip. Correspondingly, the reaction force of the sealing strip on the cabinet door is also large. Since the cabinet door and the cabinet body are hinged by connecting the two connecting structures of the hinge to the cabinet door and the cabinet body respectively, and the positions of the two connecting structures of the hinge relative to the rotating shaft are fixed, the radius trajectory of the two connecting structures relative to the rotating shaft is fixed. When it is used in a sealed cabinet, the rotation trajectory of the cabinet door relative to the cabinet body is fixed, and in order to make the cabinet door sealably cover the cabinet body, the distance between the cabinet door and the cabinet body on the hinged side is small. However, with this structure, when the cabinet door is opened and closed, the cabinet door will squeeze and scratch the sealing strip near the hinge side. When the cabinet door squeezes the sealing strip with a large force, it will be subjected to the reaction force of the sealing strip, resulting in a lever effect. When a thicker sealing strip with a large compression amount is used for the sealing strip, the cabinet door is difficult to close, and when a thinner sealing strip is used, the sealing may fail. The cabinet door squeezes and scrapes the sealing strip, even damaging it and affecting the sealing effect. In addition, when closing the cabinet door, it first squeezes the sealing strip near the hinge, causing greater compression there, while the sealing strips on the other sides of the door opening will be less compressed, resulting in uneven compression of the sealing strip around the door opening, which also affects the sealing effect.

[0069] Based on the above considerations, in order to solve the problem that the cabinet door is closer to the cabinet body when rotating and squeezes the sealing strip due to the fixed radius trajectory of the two connecting structures of the hinge relative to the rotating shaft, the embodiment of the present application provides a hinge structure, so that at least one connecting structure of the hinge structure uses an adjustment mechanism, and the first component of the adjustment mechanism is movably connected to the second component, so that the position of the second component relative to the rotating shaft is adjustable, and when rotating, the radius trajectory of the second component relative to the rotating shaft is adjustable. When applied to a sealed cabinet, the distance between the cabinet door and the cabinet body can be adjusted; before the cabinet door rotates relative to the cabinet body, the cabinet door can be moved away from the cabinet body by the adjustment mechanism to reduce the squeezing of the sealing strip. The hinge structure disclosed in the embodiment of the present application can be applied to the connection between cabinet doors and cabinet bodies that need to be sealed, such as in sealed cabinets such as power storage cabinets, switch cabinets, and distribution cabinets that require cabinet door sealing. Of course, the hinge structure can also be applied to other structures that require door panels to open and close, such as door and window support structures.

[0070] The power storage cabinets of the embodiments of the present application can be used in electrical devices or energy storage systems that need to store and release electrical energy, such as energy storage power supply systems such as hydropower, thermal power, wind power, and solar power stations. Electrical devices can include, but are not limited to, electric toys, power tools, mobile charging stations, battery-powered vehicles, electric vehicles, ships, spacecraft, and the like. Electric toys can include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric airplane toys, and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, among others.

[0071] For the convenience of description, an electric device is provided in accordance with an embodiment of the present application, and the electric device is described by taking a mobile charging station as an example.

[0072] Please refer to Figure 1, which is a schematic diagram of the structure of a mobile charging station 1000 provided in some embodiments of the present application. Mobile charging station 1000 includes a vehicle 1002 and a power storage cabinet 1001. Vehicle 1002 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle. Power storage cabinet 1001 can be installed on vehicle 1002. Power storage cabinet 1001 can be used to power vehicle 1002. For example, power storage cabinet 1001 can serve as the operating power source of vehicle 1002. Power storage cabinet 1001 can also serve as a power source for external charging.

[0073] In some embodiments of the present application, the power storage cabinet 1001 can not only serve as the operating power source of the vehicle 1002, but also serve as the driving power source of the vehicle 1002, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1002.

[0075] The power storage cabinet 1001 includes a cabinet body 10 and a cabinet door 20. The cabinet body 10 is provided with a door opening 12 for storing battery cells 50 or other devices in the cabinet body 10. The cabinet body 10 is a box or shell structure with a receiving space 11 for storing items such as batteries.

[0076] One side of the cabinet door 20 is connected to the cabinet body 10 via a hinge structure 30 to support the cabinet door 20 on the cabinet body 10. The cabinet door 20 can also rotate relative to the cabinet body 10 to open and close the cabinet door 20, thereby opening or closing the door opening 12. A sealing strip 42 is provided around the periphery of the cabinet door 20. When the cabinet door 20 is closed on the cabinet body 10, the cabinet door 20 presses the sealing strip 42 against the cabinet body 10, and the sealing strip 42 seals the gap between the cabinet door 20 and the cabinet body 10. The sealing strip 42 also surrounds the door opening 12 to cover the door opening 12. In some embodiments, a sealing strip 42 can also be provided around the door opening 12 on the cabinet body 10. When the cabinet door 20 is closed on the cabinet body 10, the cabinet door 20 presses the sealing strip 42 against the cabinet body 10, and the sealing strip 42 seals the gap between the cabinet door 20 and the cabinet body 10. The sealing strip 42 also surrounds the door opening 12 to cover the door opening 12. In some embodiments, sealing strips 42 may be provided on the periphery of the cabinet door 20 and the cabinet body 10 , respectively. Two circles of sealing strips 42 may be provided around the door opening 12 to enhance the sealing effect.

[0078] In some embodiments, one or more sealing strips 42 may be provided around the door opening 12 so as to seal the door opening 12 after the cabinet door 20 is locked on the cabinet body 10. Providing multiple sealing strips 42 may improve the sealing effect.

[0079] In some embodiments, sealing strips 42 may be provided around the periphery of the cabinet door 20 and the periphery of the door opening 12 . When the cabinet door 20 is locked on the cabinet body 10 , multiple circles of sealing strips 42 may be provided to enhance the sealing effect.

[0080] In some embodiments, the cabinet body 10 is further provided with a locking structure 41, such as a bolt, a quick-release rod, etc. When the cabinet door 20 is closed, the cabinet door 20 can be locked on the cabinet body 10, and the cabinet door 20 can be pressed against the sealing strip 42 on the cabinet body 10 to ensure a good seal.

[0081] Please refer to Figures 3, 6 to 8. According to some embodiments of the present application, the present application provides a hinge structure 30, including: two connecting structures 32; and, a rotating shaft 31, rotatably connecting the two connecting structures 32; at least one connecting structure 32 includes an adjusting mechanism 33, the adjusting mechanism 33 includes a first component 331 and a second component 332, the first component 331 is connected to the rotating shaft 31, and the second component 332 is movably connected to the first component 331 along a direction perpendicular to the axial direction of the rotating shaft 31.

[0082] The hinge structure 30 is a structure consisting of two or more objects connected to each other so that they can rotate relative to each other. The hinge structure 30 is used to connect and support the movement of objects.

[0083] The connecting structure 32 is the structure within the hinge structure 30 that connects two components that need to rotate relative to each other. The connecting structure 32 can be a block or plate. The two connecting structures 32 can be identical in shape for ease of fabrication. Of course, the shapes of the two connecting structures 32 can also differ, allowing for structural and shape adjustments based on installation requirements.

[0084] The rotating shaft 31 refers to a rotating shaft in a mechanical device, which is used to support and rotate mechanical parts. The outer contour of the rotating shaft 31 is generally set to be cylindrical so that the two connected parts can rotate with each other.

[0085] The two connecting structures 32 are respectively connected to the rotating shaft 31 so that the two connecting structures 32 can rotate relative to each other, thereby forming a hinge structure 30. For example, one connecting structure 32 can be fixedly connected to the rotating shaft 31, and the other connecting structure 32 can be rotationally connected to the rotating shaft 31 so that the two connecting structures 32 can rotate relative to each other. Of course, both connecting structures 32 can be rotationally connected to the rotating shaft 31, which can also achieve mutual rotation between the two connecting structures 32.

[0086] The adjustment mechanism 33 is a mechanism capable of adjusting the length in one direction.

[0087] At least one connecting structure 32 includes an adjustment mechanism 33, which means that one of the two connecting structures 32 includes an adjustment mechanism 33, or both connecting structures 32 include an adjustment mechanism 33. The connecting structure 32 includes the adjustment mechanism 33, so that the adjustment mechanism 33 can provide a travel for the connecting structure 32. In other words, the adjustment mechanism 33 is used by the connecting structure 32 to achieve a travel of the connecting structure 32 in a direction perpendicular to the axial direction of the rotating shaft 31.

[0088] The connection structure 32 providing a travel means that the connection structure 32 can move a distance in one direction, or the connection structure 32 can extend a distance in one direction, such as being able to telescope and move a distance in one direction, or slide a distance in one direction, etc.

[0089] Providing a stroke in a direction perpendicular to the axial direction of the rotating shaft 31 means that the direction of the stroke is perpendicular to the axial direction of the rotating shaft 31. As shown in Figures 3 and 7, the X direction is parallel to the axial direction of the rotating shaft 31, and the Y direction is perpendicular to the axial direction of the rotating shaft 31. The direction of the stroke is parallel to the Y direction.

[0090] The first component 331 is a component that constitutes the adjustment mechanism 33. The first component 331 can be configured as a block, or alternatively, as a plate or other shaped component. The second component 332 is another component that constitutes the adjustment mechanism 33. The second component 332 can be configured as a block, or alternatively, as a plate or other shaped component. The first component 331 and the second component 332 are movably connected to form the main body of the adjustment mechanism 33. Of course, the connection structure 32 may also include auxiliary structures that are compatible with the adjustment mechanism 33. For example, the connection structure 32 may include a damping member to limit the relative position of the first component 331 and the second component 332 in the adjustment mechanism 33 to a certain extent. For example, the connection structure 32 may also include a pushing member to move the second component 332 relative to the first component 331.

[0091] The first component 331 and the second component 332 can be slidably connected so that the first component 331 can slide relative to the second component 332 in an axial direction perpendicular to the rotating shaft 31 to increase the travel distance. Of course, the first component 331 and the second component 332 can be connected in a sleeve-type manner to form a telescopic structure. The first component 331 and the second component 332 can also be connected by a structure such as a telescopic frame to enable the first component 331 to move relative to the second component 332 in an axial direction perpendicular to the rotating shaft 31. In this way, during rotation, the position of the second component 332 relative to the rotating shaft 31 can be adjusted, that is, the radius of the second component 332's rotation relative to the rotating shaft 31 can be adjusted.

[0092] The adjustment mechanism 33 is used to provide a travel range by relatively movably connecting the first component 331 and the second component 332 of the adjustment mechanism 33 . The structure is relatively simple and easy to assemble and install.

[0093] When the connecting structure 32 can provide a stroke, when in use, two connecting structures 32 are respectively connected to two devices. Then, before rotation, the connecting structure 32 can provide a stroke, so that the relative positions of the two devices are pulled apart. In this way, the relative positions of the two devices are always far apart during rotation, thereby reducing the risk of interference between the two devices and facilitating rotation.

[0094] When one connecting structure 32 includes an adjusting mechanism 33, in use, the second component 332 of the adjusting mechanism 33 can be connected to the cabinet body 10, and the other connecting structure 32 can be connected to the cabinet door 20, so as to hinge the cabinet door 20 to the cabinet body 10. Of course, when one connecting structure 32 includes an adjusting mechanism 33, the second component 332 of the adjusting mechanism 33 can also be connected to the cabinet door 20, and the other connecting structure 32 can be connected to the cabinet body 10, so as to hinge the cabinet door 20 to the cabinet body 10.

[0095] When the two connection structures 32 respectively include an adjustment mechanism 33 , the second components 332 of the two adjustment mechanisms 33 can be connected to the cabinet door 20 and the cabinet body 10 respectively, so as to hinge the cabinet door 20 to the cabinet body 10 .

[0096] In the technical solution of the embodiment of the present application, an adjustment mechanism 33 is used through at least one connecting structure 32 of the hinge structure 30, and the first component 331 and the second component 332 of the adjustment mechanism 33 are movably connected to realize that the corresponding connecting structure 32 of the hinge structure 30 can be extended and retracted to provide a stroke, so that the position of the second component 332 of the connecting structure 32 and the rotating shaft 31 can be adjusted. Accordingly, when in use, the position of the device connected to the second component 332 relative to the rotating shaft 31 can be adjusted to facilitate the mutual rotation of the two devices connected by the hinge structure 30; especially when used in a sealed cabinet, before the cabinet door 20 rotates relative to the cabinet body 10, the cabinet door 20 is moved away from the cabinet body 10 through the adjustment mechanism 33 to reduce the squeezing of the sealing strip 42.

[0097] When the hinge structure 30 of the embodiment of the present application is applied to the power storage cabinet 1001, the process of opening and closing the cabinet door 20 can be as follows: at least one connecting structure 32 of the hinge structure 30 uses an adjustment mechanism 33, and the first component 331 of the adjustment mechanism 33 is movably connected to the second component 332 to provide a stroke. When in use, the two connecting structures 32 can be connected to the cabinet body 10 and the cabinet door 20 respectively, and the second component 332 of the connecting structure 32 using the adjustment mechanism 33 is connected to the cabinet door 20 or the cabinet body 10. Before the cabinet door 20 rotates relative to the cabinet body 10, the second component 332 can be moved away from the rotating shaft 31 to move the cabinet door 20 away from the cabinet body 10. In this way, when the cabinet door 20 is closed, the cabinet door 20 is relatively closed. The cabinet door 20 is rotated to a position away from the cabinet body 10 so that it is approximately parallel to the side of the cabinet body 10 close to the cabinet door 20, and a gap is formed between the cabinet door 20 and the cabinet body 10, thereby reducing the squeezing of the sealing strip 42 on the side close to the hinge structure 30, making it easier to close the cabinet door 20. The cabinet door 20 is then locked on the cabinet body 10, so that the cabinet door 20 can press the sealing strip 42 more evenly to improve the sealing effect; and after the cabinet door 20 is unlocked, the sealing strip 42 will push the cabinet door 20 to move approximately horizontally away from the cabinet body 10. When the cabinet door 20 is opened, the squeezing of the sealing strip 42 on the side close to the hinge structure 30 can be reduced, making it easier to open the cabinet door 20; since the squeezing of the sealing strip 42 is reduced, the service life of the sealing strip 42 can also be increased.

[0098] In some embodiments, the first component 331 of the adjustment mechanism 33 can be directly connected to the rotating shaft 31. Of course, the first component 331 can also be connected to the rotating shaft 31 through other connecting parts, such as a sleeve or other structures.

[0099] In some embodiments, the second component 332 can be used to directly connect to the component of the hinge structure 30 that needs to be connected, or can be connected to the component of the hinge structure 30 that needs to be connected through structures such as a connecting block and a mounting seat.

[0100] In some embodiments, the adjustment mechanism 33 further includes an elastic member 336 , which elastically presses against the first member 331 in a direction away from the second member 332 .

[0101] The elastic member 336 refers to a structural member that can be elastically deformed, such as a spring, a spring, an elastic rope, etc.

[0102] An elastic member 336 is provided to elastically push the first component 331 away from the second component 332 . After the first component 331 is unlocked, the first component 331 can be elastically pushed away, automatically increasing the gap between the first component 331 and the second component 332 , thereby increasing the adjustment space of the two connecting structures 32 .

[0103] In addition, when in use, closing the cabinet door 20 can allow the cabinet door 20 to rotate to a position nearly parallel to the door opening 12 of the cabinet body 10 and to be spaced a certain distance away from the cabinet body 10, so as to reduce the squeezing of the sealing strip 42 on the side close to the hinge structure 30, thereby facilitating locking the cabinet door 20 on the cabinet body 10; and after unlocking the cabinet door 20, the sealing strip 42 and the elastic member 336 can jointly push the cabinet door 20 away from the cabinet body 10 so as to open the cabinet door 20.

[0104] In some embodiments, the elastic member 336 is disposed between the first member 331 and the second member 332 , and two ends of the elastic member 336 respectively abut against the first member 331 and the second member 332 ;

[0105] The elastic member 336 can be an elastic compression member. The elastic member 336 is disposed between the first member 331 and the second member 332 to push the first member 331 and the second member 332 away from each other, which also facilitates the installation of the elastic member 336 .

[0106] An elastic compression member is a member that is pre-compressed and shortened during use, giving it an expectation of lengthening, thereby elastically pushing objects at both ends away from each other.

[0107] In some embodiments, the adjustment mechanism 33 further includes a guide rail 333 , which is mounted on the second component 332 , and the first component 331 is slidably mounted on the guide rail 333 .

[0108] The guide rail 333 refers to a structural member that guides an object to slide, and the guide rail 333 can be a cylindrical member, a long block member, etc.

[0109] The guide rail 333 is installed on the second member 332 to support the guide rail 333 through the second member 332 .

[0110] The first component 331 is slidably mounted on the guide rail 333, so that the guide rail 333 guides the sliding movement of the first component 331, thereby providing a travel range for the first component 331 to move on the guide rail 333. Furthermore, the guide rail 333 can also support the first component 331. It is understood that the first component 331 can also be directly supported by the second component 332, such as by partially supporting the first component 331 on the second component 332, so that the second component 332 supports the first component 331.

[0111] The guide rail 333 is provided to guide the first component 331 to move relative to the second component 332, so that the movement is more stable; and the guide rail 333 can also support the first component 331 to increase the structural strength.

[0112] In some embodiments, a slide groove can also be set on the second component 332, and a slider that cooperates with the slide groove can be set on the first component 331 to enable the first component 331 to be slidably installed on the second component 332, which can both guide the first component 331 to slide on the second component 332 and support the first component 331 through the second component 332.

[0113] In some embodiments, the guide rail 333 is cylindrical, and a sliding hole (not shown) is provided on the first component 331 , and the sliding hole is sleeved on the guide rail 333 .

[0114] Cylindrical refers to a structural part with a circular cross-section.

[0115] The sliding hole refers to a through hole provided on the first component 331. The sliding hole is adapted to the cylindrical guide rail 333, and the guide rail 333 can be inserted into the sliding hole to guide the first component 331 to slide and also support the first component 331.

[0116] The cylindrical guide rail 333 has a simple structure, is easy to manufacture, and improves the processing and assembly accuracy.

[0117] In some embodiments, the guide rail 333 may also be configured in other shapes, such as a polygonal cross-section.

[0118] In some embodiments, guide rails 333 are respectively provided at both ends of the second component 332 along the axial direction of the rotating shaft 31 , and sliding holes are respectively provided at both ends of the first component 331 .

[0119] The two ends of the second component 332 along the axial direction of the rotating shaft 31 mean that the two ends of the second component 332 are the two ends along the axial direction of the rotating shaft 31, that is, the direction from one end to the other end of the second component 332 is parallel to the axial direction of the rotating shaft 31.

[0120] The two ends of the first component 331 refer to the two ends of the first component 331 along the axial direction of the rotating shaft 31. Slide holes are respectively provided at both ends of the first component 331 to receive the guide rails 333 at both ends of the second component 332, which can not only smoothly guide the movement of the first component 331, but also better support the first component 331.

[0121] Guide rails 333 are respectively provided at both ends of the second component 332 to support and guide the movement of the first component 331 . The structure is simple, and the first component 331 can be supported more stably, thereby improving the structural strength.

[0122] In some embodiments, the adjustment mechanism 33 further includes a locking structure 334 for locking the relative positions of the first component 331 and the second component 332 .

[0123] The locking structure 334 is a structure used to relatively fix two components. In this embodiment, the locking structure 334 is used to lock the relative positions of the first component 331 and the second component 332 to relatively fix the first component 331 and the second component 332.

[0124] The locking structure 334 can fix the positions of the first component 331 and the second component 332 relatively, so that when in use, the cabinet door 20 can be conveniently locked on the cabinet body 10, which is convenient for installation and use.

[0125] In some embodiments, the locking structure 334 includes a screw 3341 and a locking nut 3342 mounted on the screw 3341, one end of the screw 3341 is connected to the second component 332, and the other end of the screw 3341 slides through the first component 331, and the locking nut 3342 is arranged on the side of the first component 331 away from the second component 332.

[0126] Screw 3341 is a rod-shaped member with external threads. Locking nut 3342 is a structural member with internal threads. The internal threads of locking nut 3342 mate with the external threads of screw 3341, forming an adaptive threaded connection between locking nut 3342 and screw 3341. Rotating locking nut 3342 allows locking nut 3342 to move axially along screw 3341.

[0127] One end of the screw rod 3341 is connected to the second component 332 so as to support the screw rod 3341 through the second component 332 .

[0128] The other end of the screw rod 3341 slides through the first component 331. This means that the first component 331 is provided with an opening, and the other end of the screw rod 3341 passes through the opening. The locking nut 3342 is located on the side of the first component 331 away from the second component 332. When the locking nut 3342 is rotated, the locking nut 3342 moves along the axial direction of the screw rod 3341, and the locking nut 3342 abuts against the first component 331, thereby locking the first component 331 relative to the second component 332.

[0129] By arranging a screw rod 3341 on the second component 332 and passing the screw rod 3341 through the first component 331, a locking nut 3342 is installed on the screw rod 3341, so that the locking nut 3342 moves on the screw rod 3341 to push the first component 331 close to the second component 332, thereby locking the position of the first component 331 relative to the second component 332. When in use, since the locking structure 334 can lock the relative position of the first component 331 and the second component 332, when locking the cabinet door 20 on the cabinet body 10, the use of the fastening structure can be reduced, which facilitates the locking and fixation of the cabinet door 20.

[0130] In some embodiments, the locking structure 334 may also use a latch, such as one that is inserted into the connection between the first component 331 and the second component 332 in a direction perpendicular to the sliding movement of the first component 331 relative to the second component 332, thereby defining the position of the first component 331 relative to the second component 332. Of course, the locking structure 334 may also use a quick-release rod, bolt, or other structure to lock the relative position of the first component 331 and the second component 332.

[0131] In some embodiments, a retaining ring 335 is provided at one end of the screw 3341 away from the second component 332 .

[0132] The snap ring 335 is a ring-shaped member with an opening on one side, which is used to clamp on the shaft to prevent objects on the shaft from falling off. The snap ring 335 is generally made of metal or plastic.

[0133] A retaining ring 335 is provided on the screw rod 3341 to reduce the risk of the locking nut 3342 falling off when the locking nut 3342 is loosened.

[0134] In some embodiments, the screw 3341 can be used as the guide rail 333, that is, the guide rail 333 and the screw 3341 are a structural member. Of course, the screw 3341 can also be fixed on the guide rail 333. In some other embodiments, the screw 3341 and the guide rail 333 can be provided separately.

[0135] In some embodiments, when a guide rail 333 is installed on the second component 332 and a spring is used as the elastic member 336 , the spring can be placed on the guide rail 333 to position and support the spring.

[0136] In some embodiments, along the axial direction of the rotating shaft 31 , one side of the middle of the first component 331 is connected to the rotating shaft 31 , the other side of the middle of the first component 331 is provided with a protrusion 3311 , and the second component 332 is provided with a groove 3321 for accommodating the protrusion 3311 .

[0137] The protrusion 3311 refers to a portion protruding from the first component 331. Providing the protrusion 3311 on the first component 331 can increase the structural strength of the first component 331.

[0138] The groove 3321 is a slot structure provided on the second component 332. The groove 3321 is adapted to the protrusion 3311 so that when the first component 331 is close to the second component 332, the protrusion 3311 can be placed in the groove 3321 so that the groove 3321 accommodates the protrusion 3311.

[0139] A protrusion 3311 is provided on the side of the middle of the first component 331 away from the rotating shaft 31, which can increase the structural strength of the first component 331, and a groove 3321 is provided on the second component 332 to accommodate the protrusion 3311, which can reduce the volume of the combination of the first component 331 and the second component 332, thereby reducing the volume of the hinge structure 30.

[0140] In some embodiments, referring to FIG8 and FIG9 , the first component 331 includes a threaded rod, and the second component 332 includes a plate. The plate is provided with a through hole 3322 , the threaded rod is inserted through the through hole 3322 , and a locking nut 3342 is installed on the threaded rod.

[0141] Threaded rod refers to a rod with external threads.

[0142] A plate is a flat structural member whose thickness is smaller than its length and width.

[0143] The through hole 3322 refers to a through hole structure provided on the plate.

[0144] Lock nut 3342 refers to a nut that cooperates with the external threads on the threaded rod.

[0145] The first component 331 uses a threaded rod, and the second component 332 uses a plate, which has a simple structure and can further simplify the structure of the hinge structure 30 and reduce costs.

[0146] Please refer to Figure 9, which is a schematic diagram of the hinge structure 30 of some embodiments of the present application. In some embodiments, the adjustment mechanism 33 includes a first component 331 and a second component 332. The first component 331 can be a threaded rod, and the second component 332 can be a plate. The plate is provided with a through-hole 3322, through which the threaded rod is inserted, and a locking nut 3342 is mounted on the threaded rod. Please also refer to Figure 8. The threaded rod supports the plate. During use, the plate can be connected to the cabinet door 20. When the cabinet door 20 is closed on the cabinet body 10, the locking nut 3342 can compress the plate, causing it to move toward the rotating shaft 31, pressing the cabinet door 20 against the cabinet body 10. When the cabinet door 20 is unlocked, the elastic force of the sealing strip 42 can push the cabinet door 20 away from the cabinet body 10, and the corresponding plate slides on the threaded rod away from the rotating shaft 31, providing a travel distance for opening the cabinet door 20.

[0147] In some embodiments, an elastic member 336 may be provided between the plate and the rotating shaft 31 to elastically support the rotating shaft 31 and the plate, so that after the plate is unwound, the elastic member 336 may elastically push the plate away from the rotating shaft 31 .

[0148] In some embodiments, a supporting portion 321 can be provided on another connecting structure 32, and the supporting portion 321 is located on both sides of the threaded rod along the axial direction of the rotating shaft 31, so that the threaded rod is located between the two supporting portions 321, and the threaded rod can rotate around the rotating shaft 31, and the elastic member 336 can abut the supporting portion 321 to facilitate the installation of the elastic member 336.

[0149] According to some embodiments of the present application, the present application provides a hinge structure 30, comprising: two connecting structures 32; and a rotating shaft 31, rotatably connecting the two connecting structures 32; at least one connecting structure 32 includes an adjustment mechanism 33, the adjustment mechanism 33 including a first component 331 connected to the rotating shaft 31 and a second component 332 slidably connected to the first component 331, the first component 331 and the second component 332 sliding relative to each other to provide a travel perpendicular to the axial direction of the rotating shaft 31. The adjustment mechanism 33 also includes a locking structure 334 for locking the relative positions of the first component 331 and the second component 332. The adjustment mechanism 33 also includes an elastic member 336, which elastically presses the first component 331 in a direction away from the second component 332. When in use, the two connecting structures 32 can be connected to the cabinet body 10 and the cabinet door 20 respectively. When the cabinet door 20 is closed, the sealing strip 42 on the cabinet body 10 will push the cabinet door 20 to be approximately parallel to the side of the cabinet body 10 close to the cabinet door 20, and form a gap between the cabinet doors 20, thereby reducing the squeezing of the sealing strip 42 on the side close to the hinge structure 30, making it easier to close the cabinet door 20. Then, the locking structure 334 pushes the first component 331 to make the first component 331 close to the second component 332, thereby closing the cabinet door 20. When the door 20 is locked on the cabinet body 10, the cabinet door 20 can press the sealing strip 42 more evenly to improve the sealing effect; after the cabinet door 20 is unlocked, the locking structure 334 unlocks the first component 331, and the elastic member 336 and the sealing strip 42 will cooperate to push the cabinet door 20 to move approximately horizontally away from the cabinet body 10. When the cabinet door 20 is opened, the squeezing of the sealing strip 42 on the side close to the hinge structure 30 can be reduced, making it easier to open the cabinet door 20; since the squeezing of the sealing strip 42 is reduced, the service life of the sealing strip 42 can also be increased.

[0150] According to some embodiments of the present application, the present application further provides a power storage cabinet 1001, comprising the hinge structure 30 described in any of the above solutions.

[0151] In some embodiments, the power storage cabinet 1001 further includes a cabinet body 10 and a cabinet door 20 , one connecting structure 32 includes an adjustment mechanism 33 , another connecting structure 32 is connected to the cabinet door 20 , and a second component 332 of the adjustment mechanism 33 is connected to the cabinet body 10 .

[0152] The second part 332 of the adjusting mechanism 33 of the other connecting structure 32 is connected to the cabinet body 10, so that the second part 332 stably supports the first part 331, and then stably supports the cabinet door 20, so that the cabinet door 20 can rotate smoothly; the first part 331 can be relatively far away from the second part 332, so that when the cabinet door 20 is closed, the cabinet door 20 can be approximately parallel to the surface where the door opening 12 of the cabinet body 10 is located, and the squeezing of the sealing strip 42 on the side close to the hinge structure 30 is reduced, which is convenient for closing the cabinet door 20, and then the cabinet door 20 is locked on the cabinet body 10, so that the cabinet door 20 can be more evenly pressed against the sealing strip 42 to improve the sealing effect; and after the cabinet door 20 is unlocked, the sealing strip 42 will push the cabinet door 20 to move approximately parallel to the cabinet body 10, and when the cabinet door 20 is opened, the squeezing of the sealing strip 42 on the side close to the hinge structure 30 can be reduced, which is convenient for opening the cabinet door 20; since the squeezing of the sealing strip 42 is reduced, the service life of the sealing strip 42 can also be increased.

[0153] According to some embodiments of the present application, the present application further provides a power storage device, including the hinge structure 30 described in any of the above solutions, or including the power storage cabinet 1001 described in any of the above solutions.

[0154] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
