Description

Technical Field

[0001] 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

[0002] Hinge hinges generally include a rotating shaft and two connecting structures connected to the rotating shaft. The two connecting structures connect two devices respectively to achieve the rotational connection of the two devices. For sealed cabinets such as power storage cabinets, switch cabinets, and distribution cabinets that require cabinet door sealing, sealing strips will be set around the cabinet door or the door opening of the cabinet body. The two connecting structures connect the cabinet door and the cabinet body respectively. Since the positions of the two connecting structures relative to the rotating shaft are fixed, the sealing strip will be squeezed when the cabinet door is opened and closed. Utility Model Content

[0003] 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 applied to a sealed cabinet, the sealing strip will be squeezed when the cabinet door is opened and closed.

[0004] In a first aspect, an embodiment of the present application provides a hinge structure, including:

[0005] two connection structures; and,

[0006] A rotating shaft, rotatably connecting the two connection structures;

[0007] At least one connection structure includes an adjustment mechanism, which includes a first component and a second component, wherein 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.

[0008] 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 applied to 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.

[0009] 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.

[0010] 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 to automatically increase the gap between the first member and the second member, thereby increasing the adjustment space of the two connection structures.

[0011] 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.

[0012] The elastic member may be an elastic compression member, and the elastic member is disposed 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.

[0013] 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.

[0014] 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 play a role in supporting the first component to increase the structural strength.

[0015] 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.

[0016] The cylindrical guide rail has a simple structure, is easy to process and manufacture, and improves the processing and assembly accuracy.

[0017] In some embodiments, two ends of the second component along the axial direction of the rotating shaft are respectively provided with guide rails, and two ends of the first component are respectively provided with sliding holes.

[0018] Guide rails are respectively arranged 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.

[0019] In some embodiments, the adjustment mechanism further includes a locking structure for locking the relative positions of the first component and the second component.

[0020] 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.

[0021] 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 a side of the first component away from the second component.

[0022] By arranging a screw rod on the second component and passing the screw rod through the first component, a locking nut is installed on the screw rod, so that the locking nut can be moved on the screw rod 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, when the cabinet door is locked on the cabinet body, the use of the fastening structure can be reduced, which facilitates the locking and fixing of the cabinet door.

[0023] In some embodiments, a clamping ring is provided at one end of the screw away from the second component.

[0024] A retaining ring is arranged on the screw rod to reduce the risk of the locking nut falling off when the locking nut is loosened.

[0025] 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.

[0026] A protrusion is provided on the side of the middle of the first component away from the rotating shaft to increase the structural strength of the first component, and a groove is provided on the second component to accommodate the protrusion, which can reduce the volume of the combination of the first component and the second component, thereby reducing the volume of the hinge structure.

[0027] In a second aspect, an embodiment of the present application provides a power storage cabinet, comprising a hinge structure as described in the above embodiment.

[0028] In some embodiments, the power storage cabinet further includes a cabinet body and a cabinet door, one connecting structure includes an adjusting mechanism, another connecting structure is connected to the cabinet door, and a second component of the adjusting mechanism is connected to the cabinet body.

[0029] A connecting structure is connected to the cabinet body, and the second component of the adjusting 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 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 hinged structure is reduced, which is convenient for closing the cabinet door, and then the cabinet door is locked on the cabinet body, so that 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 hinged 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.

[0030] In a third aspect, an embodiment of the present application provides a power storage device, including the hinge structure as described in the above embodiment, or including the power storage cabinet as described in the above embodiment.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments in any suitable manner.

[0049] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two), and similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces). "Several" means one or more than one, unless otherwise clearly and specifically defined.

[0052] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

For another example, when there are multiple C components, the multiple C components are C1, C2, ..., C N When one of the C components, such as C2, is closer to the B component than other C components, then B is adjacent to C2, or it can be said that C2 is adjacent to B.

[0055] At present, with the vigorous development of new energy, the use of new energy power batteries is increasing. New energy batteries have the advantages of high cost performance, good safety, low pollution, etc., and have been more and more widely used, not only in the field of general electronics, but also gradually in the field of power and energy storage. Power batteries are not only used in energy storage power supply systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric vehicles, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding. As the core component of new energy power devices, the safety of power batteries directly affects the safety performance of power devices.

[0056] A sealed cabinet refers to a cabinet structure whose door can be well sealed with the cabinet body.

[0057] The power storage cabinet is a highly concentrated energy storage device formed by placing multiple batteries or battery cells in a sealed cabinet. When used, it can be used as a power battery. Since the battery formed by the battery cells inside the cabinet has a high voltage or large capacity, when the battery thermally runs away, a large amount of high-temperature and high-pressure gas will be generated. This high-temperature and high-pressure gas will accumulate in the cabinet of the power storage cabinet, causing an explosion. In response to this, the power storage cabinet is often filled with nitrogen to reduce the fire safety hazards caused by thermal runaway of the batteries inside the cabinet.

[0058] In the embodiment of the present application, the 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 the 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 the battery cell includes but is not limited to a cylinder, a flat body, a rectangular parallelepiped or other shapes. Battery cells are generally divided into cylindrical battery cells, square battery cells and soft-pack battery cells according to the packaging method, including but not limited to: cylindrical battery cells, square battery cells and soft-pack battery cells.

[0059] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the present application may include a battery module or a battery pack, etc. The battery generally includes a casing for encapsulating one or more battery cells. The casing can prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells to a certain extent. 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.

[0060] In a battery, when there are multiple battery cells, the multiple battery cells can be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells are connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells is accommodated in a box; of course, the battery can also be a battery module formed by connecting multiple battery cells in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in a box. The battery can also include other structures. For example, the battery can also include a busbar component for realizing electrical connection between multiple battery cells.

[0061] A hinge generally includes a rotating shaft and two connecting structures connected to the rotating shaft, and the two connecting structures are respectively connected to two devices to achieve a rotational connection between the two devices.

[0062] The structure of a sealed cabinet mainly includes a cabinet body and a cabinet door. The cabinet body is provided with a door opening so that objects can be placed in the cabinet body, such as battery cells, to form a power storage cabinet. One side of the cabinet door is generally hinged to the cabinet body using a hinge to rotate the cabinet door and facilitate the opening and closing of the cabinet door. In order to seal the door opening of the cabinet body well and reduce the risk of gas leakage inside the cabinet body and external gas entering the cabinet body, a sealing strip is often provided around the door opening on the cabinet body, or a sealing strip is provided around the cabinet door. When the cabinet door is locked on the cabinet body, the cabinet door presses against the sealing strip to seal the door opening.

[0063] In order to improve the sealing effect, a sealing strip with a large compression amount is generally provided, and the compression amount of the cabinet door on the sealing strip is also large. 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 hinge to the cabinet door and the cabinet body respectively, and the positions of the two connecting structures of the hinge 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 applied to a sealed cabinet, the rotation trajectory of the cabinet door relative to the cabinet body is fixed, and in order to allow the cabinet door to be sealed on the cabinet body, the distance between the cabinet door and the cabinet body is small on the hinged side of the cabinet door. However, in 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 subject to the reaction force of the sealing strip, resulting in a lever effect. When the sealing strip uses a thicker sealing strip with a large compression amount, the cabinet door is difficult to close, and when a thinner sealing strip is used, the sealing may fail. The cabinet door squeezes and scratches the sealing strip, or even damages it, which affects the sealing effect. In addition, when closing the cabinet door, the cabinet door will first squeeze the sealing strip near the hinge, causing the sealing strip to be compressed more, while the sealing strips on other sides of the door opening will be compressed less, resulting in uneven compression of the sealing strips around the door opening, which will also affect the sealing effect.

[0064] Based on the above considerations, in order to solve the problem that the cabinet door is close to the cabinet body when rotating and squeezes the sealing strip because the radius trajectory of the two connecting structures of the hinge relative to the rotating shaft is fixed, 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 the cabinet door and the cabinet body that needs to be sealed, such as it can be applied to 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.

[0065] The power storage cabinet of the embodiment of the present application can be applied to power devices or energy storage systems that need to store and release electric energy, such as energy storage power supply systems such as hydropower, thermal power, wind power and solar power stations. The power device can be, but is not limited to, electric toys, electric tools, mobile charging stations, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles and spacecraft, etc.

[0066] 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.

[0067] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a mobile charging station 1000 provided in some embodiments of the present application. The mobile charging station includes a vehicle 1002 and a power storage cabinet 1001. The vehicle 1002 may be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle. The power storage cabinet 1001 may be arranged on the vehicle 1002. The power storage cabinet 1001 may be used to power the vehicle 1002. For example, the power storage cabinet 1001 may be used as an operating power source for the vehicle 1002. The power storage cabinet 1001 may also be used as a power source for external charging.

[0068] In some embodiments of the present application, the power storage cabinet 1001 can not only serve as an operating power source for the vehicle 1002 , but also serve as a driving power source for the vehicle 1002 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1002 .

[0070] 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 so as to store battery cells 50 or other devices in the cabinet body 10. The cabinet body 10 refers to a box or shell structure with a receiving space 11 for storing items such as batteries.

[0071] One side of the cabinet door 20 is connected to the cabinet body 10 through a hinge structure 30 to support the cabinet door 20 on the cabinet body 10, and the cabinet door 20 can rotate relative to the cabinet body 10 so as to open and close the cabinet door 20, thereby opening or closing the door opening 12. A sealing strip 42 is provided around 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, the sealing strip 42 seals the interval between the cabinet door 20 and the cabinet body 10, and the sealing strip 42 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, the sealing strip 42 seals the interval between the cabinet door 20 and the cabinet body 10, and the sealing strip 42 surrounds the door opening 12 to cover the door opening 12. In some embodiments, sealing strips 42 may be respectively provided on the periphery of the cabinet door 20 and the cabinet body 10 , and two circles of sealing strips 42 may be provided around the door opening 12 to improve the sealing effect.

[0072] In some embodiments, one or more sealing strips 42 may be provided around the cabinet door 20 so that the door opening 12 can be sealed after the cabinet door 20 is locked on the cabinet body 10. Providing multiple sealing strips 42 can improve the sealing effect.

[0073] In some embodiments, one or more sealing strips 42 may be provided around the door opening 12 so that the door opening 12 can be sealed after the cabinet door 20 is locked on the cabinet body 10. Providing multiple sealing strips 42 can improve the sealing effect.

[0074] In some embodiments, sealing strips 42 may be provided around the cabinet door 20 and 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 improve the sealing effect.

[0075] In some embodiments, a locking structure 41 is further provided on the cabinet body 10, such as a bolt, a quick-release rod or the like.

[0076] See also Figure 3 , Figures 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.

[0077] The hinge structure 30 refers to 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.

[0078] The connection structure 32 refers to a structure in the hinge structure 30 used to connect two devices that need to rotate with each other. The connection structure 32 can be a block-shaped piece, or a plate-shaped piece, etc. The shapes of the two connection structures 32 can be set to be the same for easy processing and manufacturing. Of course, the shapes of the two connection structures 32 can also be set to be different, so that the corresponding structure and shape can be adjusted according to installation needs.

[0079] The rotating shaft 31 refers to a rotating shaft in a mechanical device, and is used to support and rotate a mechanical component. The outer contour of the rotating shaft 31 is generally set to be cylindrical, so that the two connected components can rotate relative to each other.

[0080] The two connection structures 32 are respectively connected to the rotating shaft 31 so that the two connection structures 32 can rotate with each other, thereby forming a hinge structure 30. For example, one connection structure 32 can be fixedly connected to the rotating shaft 31, and the other connection structure 32 can be rotatably connected to the rotating shaft 31 so that the two connection structures 32 can rotate with each other. Of course, both connection structures 32 can be rotatably connected to the rotating shaft 31, and the two connection structures 32 can also rotate with each other.

[0081] The adjustment mechanism 33 is a mechanism capable of adjusting the length in one direction.

[0082] At least one connection structure 32 includes the adjustment mechanism 33, which means that one of the two connection structures 32 includes the adjustment mechanism 33, or the two connection structures 32 respectively include the adjustment mechanism 33. The connection structure 32 includes the adjustment mechanism 33, so that a stroke can be provided for the connection structure 32 through the adjustment mechanism 33. In other words, the adjustment mechanism 33 is used by the connection structure 32 to realize that the connection structure 32 provides a stroke in a direction perpendicular to the axial direction of the rotating shaft 31.

[0083] The connection structure 32 providing a travel means that the connection structure 32 can move a certain distance in one direction, or the connection structure 32 can extend a certain distance in one direction, such as being able to telescope and move a certain distance in one direction, or slide a certain distance in one direction, etc.

[0084] 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. Figure 3 and Figure 7 As shown, 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 , and the direction of this section of travel is parallel to the Y direction.

[0085] The first component 331 refers to a component constituting the adjustment mechanism 33. The first component 331 can be set as a block. Of course, the first component 331 can also be set as a plate or other shaped components. The second component 332 refers to another component constituting the adjustment mechanism 33. The second component 332 can be set as a block. Of course, the second component 332 can also be set as a plate or other shaped components. The first component 331 is movably connected with the second component 332 to form the main body of the adjustment mechanism 33. Of course, the connection structure 32 can also include some auxiliary structures adapted to the adjustment mechanism 33. For example, the connection structure 32 can 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 through the damping member. For example, the connection structure 32 can also include a pusher to move the second component 332 relative to the first component 331.

[0086] 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 along the axial direction perpendicular to the rotating shaft 31 to increase a certain stroke. Of course, the first component 331 and the second component 332 can be connected in a sleeve 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 along the axial direction perpendicular to the rotating shaft 31, so that when rotating, the position of the second component 332 relative to the rotating shaft 31 can be adjusted, that is, the radius trajectory of the second component 332 rotating relative to the rotating shaft 31 can be adjusted.

[0087] The adjusting mechanism 33 is used to provide a travel by relatively movably connecting the first component 331 and the second component 332 of the adjusting mechanism 33. The structure is relatively simple and easy to assemble and install.

[0088] When the connection structure 32 can provide a stroke, when in use, the two connection structures 32 are respectively connected to two devices. Then, before rotation, the connection structure 32 can provide a stroke to pull the two devices apart relative to each other. In this way, the two devices are always far apart relative to each other during rotation, thereby reducing the risk of interference between the two devices and facilitating rotation.

[0089] When one connection structure 32 includes an adjustment mechanism 33, in application, the second part 332 of the adjustment mechanism 33 can be connected to the cabinet 10, and the other connection structure 32 can be connected to the cabinet door 20, so that the cabinet door 20 is hinged to the cabinet 10. Of course, when one connection structure 32 includes an adjustment mechanism 33, the second part 332 of the adjustment mechanism 33 can also be connected to the cabinet door 20, and the other connection structure 32 can be connected to the cabinet 10, so that the cabinet door 20 is hinged to the cabinet 10.

[0090] When the two connection structures 32 respectively include an adjustment mechanism 33 , the second components 332 of the two adjustment mechanisms 33 can be respectively connected to the cabinet door 20 and the cabinet body 10 , so as to hinge the cabinet door 20 to the cabinet body 10 .

[0091] 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.

[0092] 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 travel. 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 The cabinet door 20 is rotated at a position relatively far away from the cabinet body 10 so that the cabinet door 20 is approximately parallel to a 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, 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. After the cabinet door 20 is unlocked, the sealing strip 42 will push the cabinet door 20 to approximately translate 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 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.

[0093] In some embodiments, the first component 331 of the adjustment mechanism 33 may be directly connected to the rotating shaft 31. Of course, the first component 331 may also be connected to the rotating shaft 31 through other connecting parts, such as a shaft sleeve and other structures.

[0094] In some embodiments, the second component 332 can be used to directly connect to the component that needs to be connected to the hinge structure 30, or can be connected to the component that needs to be connected to the hinge structure 30 through structures such as a connecting block and a mounting seat.

[0095] In some embodiments, the adjustment mechanism 33 further includes an elastic member 336 , and the elastic member 336 elastically presses against the first member 331 in a direction away from the second member 332 .

[0096] The elastic member 336 refers to a structural member that can be elastically deformed, such as a spring, a spring sheet, an elastic rope, etc.

[0097] 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 to automatically increase the gap between the first component 331 and the second component 332 , thereby increasing the adjustment space of the two connecting structures 32 .

[0098] In addition, when in use, closing the cabinet door 20 can cause 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 from the cabinet body 10, so as to reduce the squeezing of the sealing strip 42 on the side close to the hinge structure, 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.

[0099] 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 ;

[0100] The elastic member 336 may be an elastic compression member, and 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 .

[0101] An elastic compression piece is one that is pre-stressed to a certain extent during use and shortened, so that it has the expectation of lengthening, thereby elastically pushing objects at both ends away from each other.

[0102] 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 .

[0103] The guide rail 333 refers to a structural member that guides an object to slide, and the guide rail 333 may be a cylindrical member, a long block member, or the like.

[0104] The guide rail 333 is installed on the second member 332 to support the guide rail 333 through the second member 332 .

[0105] The first component 331 is slidably mounted on the guide rail 333, so that the guide rail 333 guides the first component 331 to slide, so that the first component 331 moves on the guide rail 333 to provide a travel. In addition, the first component 331 can also be supported by the guide rail 333. It can be understood that the first component 331 can also be directly supported by the second component 332, such as supporting part of the first component 331 on the second component 332, so that the second component 332 supports the first component 331.

[0106] 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.

[0107] In some embodiments, a slide groove may be provided on the second component 332, and a slider cooperating with the slide groove may be provided 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.

[0108] 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 .

[0109] Cylindrical refers to a structural part with a circular cross-section.

[0110] 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 can also support the first component 331.

[0111] The cylindrical guide rail 333 has a simple structure, is easy to manufacture, and improves the processing and assembly accuracy.

[0112] In some embodiments, the guide rail 333 may also be configured in other shapes, such as a polygonal cross-section.

[0113] In some embodiments, two ends of the second component 332 along the axial direction of the rotating shaft 31 are respectively provided with guide rails 333 , and two ends of the first component 331 are respectively provided with sliding holes.

[0114] 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.

[0115] 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 the two ends of the first component 331 to be correspondingly inserted into the guide rails 333 at the two 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.

[0116] 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 can more stably support the first component 331, thereby improving the structural strength.

[0117] 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 .

[0118] The locking structure 334 refers to 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.

[0119] The locking structure 334 is provided to relatively fix the positions of the first component 331 and the second component 332 , 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.

[0120] 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.

[0121] The screw rod 3341 is a rod-shaped member with an external thread. The locking nut 3342 is a structural member with an internal thread. The internal thread of the locking nut 3342 cooperates with the external thread of the screw rod 3341, and the locking nut 3342 and the screw rod 3341 are connected by fitting threads. The locking nut 3342 is rotated to move the locking nut 3342 along the axial direction of the screw rod 3341.

[0122] One end of the screw rod 3341 is connected to the second component 332 so that the screw rod 3341 is supported by the second component 332 .

[0123] The other end of the screw rod 3341 slides through the first component 331, which means that an opening is provided on the first component 331, 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 position of the first component 331 relative to the second component 332.

[0124] By setting a screw rod 3341 on the second component 332 and passing the screw rod 3341 through the first component 331, and installing a locking nut 3342 on the screw rod 3341, the locking nut 3342 can be moved 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 the cabinet door 20 is locked on the cabinet body 10, the use of the fastening structure can be reduced, thereby facilitating the locking and fixing of the cabinet door 20.

[0125] In some embodiments, the locking structure 334 may also use a latch, such as inserting the latch into the connection between the first component 331 and the second component 332 in a direction perpendicular to the sliding direction of the first component 331 relative to the second component 332, so as to limit the position of the first component 331 relative to the second component 332 through the latch. Of course, the locking structure 334 may also use a quick release rod, a bolt, or other structures to lock the relative position of the first component 331 and the second component 332.

[0126] In some embodiments, a retaining ring 335 is provided at one end of the screw 3341 away from the second component 332 .

[0127] 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.

[0128] 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.

[0129] In some embodiments, the screw rod 3341 can be used as the guide rail 333, that is, the guide rail 333 and the screw rod 3341 are a structural member. Of course, the screw rod 3341 can also be fixed on the guide rail 333. In some other embodiments, the screw rod 3341 and the guide rail 333 can be provided separately.

[0130] 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 sleeved on the guide rail 333 to position and support the spring.

[0131] 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 , a protrusion 3311 is provided on the other side of the middle of the first component 331 , and a groove 3321 for accommodating the protrusion 3311 is provided on the second component 332 .

[0132] 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.

[0133] The groove 3321 refers to 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.

[0134] 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.

[0135] See also Fig. 9 , Fig. 9 Schematic diagram of the structure 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. A through hole 3322 is provided on the plate, so that the threaded rod is inserted into the through hole 3322, and a locking nut is installed on the threaded rod. Please refer to Figure 8 , so that the plate is supported by the threaded rod, and when in use, the plate can be connected to the cabinet door 20, so that when the cabinet door 20 is closed on the cabinet body 10, the plate can be pressed by the locking nut 3342 to move the plate close to the rotating shaft 31 to press the cabinet door 20 against the cabinet body 10. When the cabinet door 20 is unlocked, the cabinet door 20 can be pushed away from the cabinet body 10 under the elastic force of the sealing strip 42, and the corresponding plate slides away from the rotating shaft 31 on the threaded rod to provide a stroke so that the cabinet door 20 can be opened.

[0136] In some embodiments, an elastic member 336 may be disposed between the plate and the rotating shaft 31 to elastically support the rotating shaft 31 and the plate, so that after the plate is unfastened, the elastic member 336 may elastically push the plate away from the rotating shaft 31 .

[0137] 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 resist the supporting portion 321 to facilitate the installation of the elastic member 336.

[0138] According to some embodiments of the present application, the present application provides a hinge structure 30, including: two connection structures 32; and, a rotating shaft 31, rotatably connecting the two connection structures 32; at least one connection structure 32 includes an adjustment mechanism 33, the adjustment mechanism 33 includes 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 slide relative to each other to provide a stroke perpendicular to the axial direction of the rotating shaft 31. The adjustment mechanism 33 also includes a locking structure 334, which is used to lock the relative position of the first component 331 and the second component 332. The adjustment mechanism 33 also includes an elastic member 336, which elastically resists 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, making it easier to close the cabinet door 20, and 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 can be reduced, thereby facilitating the opening of 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.

[0139] 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.

[0140] In some embodiments, the power storage cabinet 1001 further includes a cabinet body 10 and a cabinet door 20 , one connection structure 32 includes an adjustment mechanism 33 , another connection 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 .

[0141] A connecting structure 32 is connected to the cabinet 10, and the second part 332 of the adjusting mechanism 33 of the other connecting structure 32 is connected to the cabinet 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 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 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 approximately translate away from the cabinet 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.

[0142] 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.
