Description

Technical Field

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

[0002] Energy storage power supplies are typically equipped with input and output sockets to power both the devices they supply and the power itself. In related technologies, flip covers are generally used to protect the sockets, preventing dust, moisture, and other impurities from entering and causing risks such as poor contact or short circuits at the connectors. However, current flip cover assembly processes are complex and costly. Utility Model Content

[0003] In view of this, this application provides a flip cover, a housing assembly, and an energy storage device, which are not only simple in structure and easy to install, but also have low production costs.

[0004] One embodiment of this application provides a flip cover. The flip cover is configured to be mounted on a housing assembly, the housing assembly including a front cover, the front cover having a receiving cavity and a mounting position for assembling a device. The flip cover includes a fastener and a flip cover body, the fastener being configured to be installed within the receiving cavity and fixedly connected to the front cover. The flip cover body is configured to be movably connected to the front cover, the flip cover body being folded into the receiving cavity to expose the device, and unfolded out of the receiving cavity to cover the device. The fastener has a first engaging portion, and the flip cover body has a second engaging portion. The second engaging portion is configured to engage with the first engaging portion when the flip cover body is folded into the receiving cavity to constrain the relative position of the flip cover body and the front cover.

[0005] The flip cover provided in this application consists of only two parts: a fastener and a flip cover body. Through the engagement of the first fastening part in the fastener and the second fastening part in the flip cover body (i.e., a snap-fit ​​structure), the flip cover can be fixed after being folded into the storage cavity, thus locking the flip cover in the folded state. Not only is the overall structure simple, but there is also no need to add other complex locking components, such as magnetic components, which helps to reduce the assembly difficulty and manufacturing cost of the flip cover.

[0006] In some embodiments of this application, the fastener further includes a mounting portion connected to the first snap-fit ​​portion. The mounting portion is configured to be welded to the faceplate. At least a portion of the first snap-fit ​​portion is configured to be elastically deformable so that the first snap-fit ​​portion can engage with the second snap-fit ​​portion through its own elastic deformation.

[0007] The first latching part is welded to the front cover via the mounting part, and when the flip cover body is folded into the receiving cavity, it can engage with the second latching part through its own elastic deformation to lock the flip cover. The welding method used for the latching mechanism improves the stability and reliability of the latching installation. Furthermore, by constructing at least a portion of the first latching part to be elastically deformable, the engagement between the latching mechanism and the flip cover body is ensured.

[0008] In some embodiments of this application, the first latching portion includes an elastic segment and a protruding segment. The elastic segment is connected to the mounting portion, and the protruding segment extends from the elastic segment toward the flip cover body. Along the folding direction of the flip cover body, the projection of the protruding segment at least partially overlaps with the projection of the second latching portion.

[0009] In some embodiments of this application, the protruding section has a guide ramp, and the second snap-fit ​​portion is configured to slide along the guide ramp when the flap body is folded into the receiving cavity.

[0010] By setting the guide slope, the risk of the flip cover jamming or getting stuck due to interference between the second latch and the protruding section when folding can be reduced, which helps to improve the smoothness of the flipping action and enhance the user experience.

[0011] In some embodiments of this application, the second latching portion has a contact surface, which is configured as an arc surface. When the flip cover body is folded into the receiving cavity, the contact surface abuts against the guide ramp.

[0012] By using a curved surface, the surface contact between the second latch and the protruding section can be changed to a point contact, thereby reducing the friction between them. This not only reduces the risk of the flip cover jamming or getting stuck, but also allows users to push or pull the flip cover more easily, improving the user experience.

[0013] In some embodiments of this application, a deformation space is formed between the elastic segment and the outer shell within the receiving cavity, and the deformation space is configured to allow the elastic segment to deform.

[0014] When the flip cover is folded into the receiving cavity, the elastic segment undergoes elastic deformation under stress and is accommodated in the deformation space. By setting up the deformation space, the risk of interference between the cover and the fasteners can be reduced, which helps to better reduce the risk of the flip cover jamming and improve the stability of the flip cover in use.

[0015] In some embodiments of this application, the flip cover body has a first surface and a second surface disposed opposite to each other. The first surface is configured to face the front cover. A second snap-fit ​​portion is provided on the first surface.

[0016] When the flip cover unfolds to the outside of the receiving cavity and covers the device, the second latching part located on the first side is housed between the flip cover body and the outer shell, thus concealing the second latching part. Firstly, this reduces the risk of the flip cover's overall visual appearance being poor due to the second latching part being exposed, which helps improve the consistency of the energy storage device's appearance. Secondly, it protects the second latching part, reducing the risk of breakage or deformation due to external forces, which helps extend the flip cover's service life.

[0017] In some embodiments of this application, the mounting portion and the first snap-fit ​​portion are constructed as an integral structure.

[0018] The "integrated structure" design of the fastener not only eliminates the connection steps between the mounting part and the first snap-fit ​​part, improving the overall installation efficiency of the flip cover, but also enhances the overall structural strength of the fastener, thus extending the lifespan of the flip cover.

[0019] One embodiment of this application provides a housing assembly. The housing assembly is applied to an energy storage device. The housing assembly includes a front shell and a flip cover as described in any of the above embodiments. The front shell has a receiving cavity and a mounting position. The mounting position is configured for assembling devices of the energy storage device. Fasteners are installed in the receiving cavity and are fixedly connected to the front shell. The flip cover body is movably connected to the front shell. The flip cover body can be folded into the receiving cavity to expose the devices and unfolded out of the receiving cavity to cover the devices.

[0020] The aforementioned housing assembly employs the aforementioned flip cover. The flip cover consists of only two parts: a fastener and a flip cover body. Through the engaging engagement of the first latching part in the fastener and the second latching part in the flip cover body (i.e., a snap-fit ​​structure), the flip cover can be fixed after being folded into the storage cavity, thus achieving locking of the flip cover in the folded state. This not only simplifies the overall structure but also eliminates the need for additional complex locking components, such as magnetic attachments, which helps reduce the assembly difficulty and manufacturing cost of the flip cover.

[0021] One embodiment of this application provides an energy storage device. The energy storage device includes a device body and the aforementioned housing assembly. The housing assembly is mounted on the device body.

[0022] The aforementioned energy storage device employs the aforementioned housing assembly. The flip cover in the housing assembly consists of only two parts: a fastener and a flip cover body. Through the snap-fit ​​cooperation between the first snap-fit ​​part in the fastener and the second snap-fit ​​part in the flip cover body (i.e., a snap-fit ​​structure), the flip cover can be fixed after being folded into the storage cavity, thus achieving locking of the flip cover in the folded state. This not only simplifies the overall structure but also eliminates the need for additional complex locking components, such as magnetic components, which helps reduce the assembly difficulty and manufacturing cost of the flip cover.

[0033] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] Energy storage power supplies are typically equipped with input and output sockets to power both the devices they supply and the power itself. In related technologies, flip covers are generally used to protect the sockets, preventing dust, moisture, and other impurities from entering and causing risks such as poor contact or short circuits at the connectors. However, current flip cover assembly processes are complex and costly.

[0036] One embodiment of this application provides a flip cover. The flip cover is configured to be mounted on a housing assembly, the housing assembly including a front cover, the front cover having a receiving cavity and a mounting position for assembling a device. The flip cover includes a fastener and a flip cover body, the fastener being configured to be installed within the receiving cavity and fixedly connected to the front cover. The flip cover body is configured to be movably connected to the front cover, the flip cover body being folded into the receiving cavity to expose the device, and unfolded out of the receiving cavity to cover the device. The fastener has a first engaging portion, and the flip cover body has a second engaging portion. The second engaging portion is configured to engage with the first engaging portion when the flip cover body is folded into the receiving cavity to constrain the relative position of the flip cover body and the front cover.

[0037] The flip cover provided in this application consists of only two parts: a fastener and a flip cover body. Through the engagement of the first fastening part in the fastener and the second fastening part in the flip cover body (i.e., a snap-fit ​​structure), the flip cover can be fixed after being folded into the storage cavity, thus locking the flip cover in the folded state. Not only is the overall structure simple, but there is also no need to add other complex locking components, such as magnetic components, which helps to reduce the assembly difficulty and manufacturing cost of the flip cover.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please refer to the following: Figures 1 to 3 One embodiment of this application provides an energy storage device 1. The energy storage device 1 has the functions of storing and discharging electricity, and can be used for household backup power, production unit backup power, outdoor work, outdoor recreation, etc.

[0040] In some embodiments, the energy storage device 1 includes a housing assembly 100 and a device body 200. The housing assembly 100 is mounted on the device body 200 and is used to protect the device body 200.

[0041] In some embodiments, the energy storage device 1 further includes a power conversion module (not shown), which is electrically connected to the device body 200. The power conversion module is used to control the AC / DC conversion of the output current of the device body 200. The energy storage device 1 equipped with the power conversion module can be a small portable power supply, a residential energy storage power supply, an industrial or commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0042] In some embodiments, the power conversion module may be omitted. The energy storage device 1 without a power conversion module can be used independently. The energy storage device 1 without a power conversion module typically only outputs DC power. When used independently, the energy storage device 1 without a power conversion module can be used in conjunction with an energy storage device 1 with a power conversion module as a power system providing additional battery capacity.

[0043] In some embodiments, the energy storage device 1 further includes a plug-in terminal 300, which is connected to the device body 200. The plug-in terminal 300 is exposed to the outside. The energy storage device 1 is connected to external devices through the plug-in terminal 300.

[0044] In some embodiments, the plug-in terminal 300 may be various USB (Universal Serial Bus) interfaces, various audio interfaces, various optical fiber interfaces, etc.

[0045] Please refer to the following: Figures 4 to 7 In some embodiments, the housing assembly 100 includes a front cover 10 and a flip cover 20. The front cover 10 is mounted to the device body 200 and has a receiving cavity 11 and a mounting position 12. The mounting position 12 is configured for assembling devices of the energy storage device 1. In the energy storage device 1, the device is a plug-in terminal 300, which is located at the mounting position 12.

[0046] In some embodiments, the flip cover 20 includes a flip cover body 21 and a fastener 22. The flip cover body 21 is movably connected to the faceplate 10, and the flip cover body 21 can be folded into the receiving cavity 11 to expose the device, and unfolded out of the receiving cavity 11 to cover the device.

[0047] Understandably, when the device needs to be used, the user can fold the flip cover 21 into the receiving cavity 11 so that the device is exposed to the outside; when the device is not in use, the user can unfold the flip cover 21 to the outside of the receiving cavity 11 and cover the device.

[0048] In some embodiments, the locking fastener 22 is installed within the receiving cavity 11 and fixedly connected to the faceplate 10. The locking fastener 22 has a first locking portion 221, and the flip cover body 21 has a second locking portion 211. When the flip cover body 21 is folded into the receiving cavity 11, the second locking portion 211 engages with the first locking portion 221 to constrain the relative position of the flip cover body 21 and the faceplate 10, thereby locking the flip cover 20.

[0049] The flip cover 20 provided in this application consists of only two parts: the flip cover body 21 and the locking fastener 22. Through the engaging engagement (i.e., a snap-fit ​​structure) between the first locking part 221 in the locking fastener 22 and the second locking part 211 in the flip cover body 21, the flip cover 20 can be fixed in the storage cavity after folding, thus locking the flip cover 20 in the folded state. Compared to existing flip covers, this design is not only simple in overall structure but also eliminates the need for additional complex locking components, such as magnetic attachments, which helps reduce the assembly difficulty and manufacturing cost of the flip cover 20.

[0050] Please refer to the following: Figures 5 to 7 In some embodiments, the fastener 22 further includes a mounting portion 222 connected to the first latching portion 221. The mounting portion 222 is configured to be welded to the faceplate 10, that is, the fastener 22 is welded to the faceplate 10 through the mounting portion 222. It should be noted that the welded structure has better structural strength, which is beneficial to improving the stability and reliability of the fastener 22 installation.

[0051] In other embodiments, the fastener 22 may also adopt other suitable connection methods such as threaded connection. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0052] In some embodiments, the first latching portion 221 is at least partially configured to be elastically deformable. When the flip cover body 21 is folded into the receiving cavity 11, the first latching portion 221 can engage with the second latching portion 211 through its own elastic deformation to lock the flip cover 20.

[0053] Specifically, the first snap-fit ​​portion 221 includes an elastic section 2211 and a protruding section 2212. The elastic section 2211 is connected to the mounting portion 222, and the protruding section 2212 extends from the elastic section 2211 toward the flip cover body 21.

[0054] Along the folding direction of the flip cover body 21 (specifically, the sliding direction of the flip cover body 21 along the receiving cavity 11), the projection of the protruding section 2212 at least partially overlaps with the projection of the second latching portion 211. In other words, the protruding section 2212 occupies part of the movement path of the flip cover body 21.

[0055] Understandably, when the flip cover body 21 is folded into the receiving cavity 11, the second latching part 211 pushes against the protruding section 2212 in the first latching part 221, and the elastic section 2211 in the first latching part 221 bends away from the flip cover body 21 under force (that is, undergoes elastic deformation) and generates elastic potential energy.

[0056] As the flip cover body 21 continues to move, the second latching part 211 passes over the protruding section 2212 in the first latching part 221. At this time, the protruding section 2212 in the first latching part 221 returns to its initial position under the action of elastic potential energy (specifically, the position of the protruding section 2212 when the elastic section 2211 has not undergone elastic deformation), and latches with the second latching part 211. That is, the first latching part 221 and the second latching part 221 are mutually locked together to constrain the relative position of the flip cover body 21 and the face shell 10.

[0057] In other embodiments, the first snap-fit ​​portion 221 and the second snap-fit ​​portion 211 may also be other suitable structures. This application does not limit them, and those skilled in the art can choose according to the actual situation.

[0058] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the protruding section 2212 has a guide ramp 22121. The second snap-fit ​​portion 211 is configured to slide along the guide ramp 22121 when the flap body 21 is folded into the receiving cavity 11.

[0059] By setting the guide slope 22121, the risk of the flip body 21 getting stuck or jammed due to interference between the second latching part 211 and the protruding section 2212 when it is folded can be reduced. This helps to improve the smoothness of the flip action and improve the user experience.

[0060] In some embodiments, the second latching portion 211 has a contact surface 2111, which is configured as an arc surface. When the flip cover body 21 is folded into the receiving cavity 11, the contact surface 2111 abuts against the guide ramp 22121.

[0061] By using a curved surface, the surface contact between the second latching part 211 and the protruding section 2212 can be changed to a point contact, thereby reducing the friction between them. This not only reduces the risk of the flip cover 20 jamming or getting stuck, but also allows users to push or pull the flip cover 20 more easily, improving the user experience.

[0062] In some embodiments, a deformation space 30 is formed between the elastic segment 2211 and the face shell 10 within the receiving cavity 11. The deformation space 30 is configured to allow the elastic segment 2211 to deform. When the flip body 21 is folded into the receiving cavity 11, the elastic segment 2211 undergoes elastic deformation under force and is accommodated in the deformation space 30.

[0063] By setting the deformation space 30, the risk of interference between the faceplate 10 and the fastener 22 can be reduced, which helps to better reduce the risk of the flip cover 20 getting stuck and improve the stability of the flip cover 20 in use.

[0064] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the flip cover body 21 has a first surface 212 and a second surface 213 disposed opposite to each other. The first surface 212 is configured to face the cover 10. A second snap-fit ​​portion 211 is provided on the first surface 212.

[0065] When the flip cover body 21 unfolds to the outside of the receiving cavity 11 and covers the device, the second latching part 211 located on the first surface 212 is received between the flip cover body 21 and the face shell 10, that is, the second latching part 211 is hidden.

[0066] Firstly, it can reduce the risk of poor overall visual effect of the flip cover 20 due to the second snap-fit ​​part 211 being exposed on the flip cover body 21, which is conducive to improving the appearance consistency of the energy storage device 1; secondly, it can protect the second snap-fit ​​part 211, reduce the risk of the second snap-fit ​​part 211 breaking or deforming due to external forces, which is conducive to extending the service life of the flip cover 20.

[0067] In some embodiments, the mounting portion 222 and the first snap-fit ​​portion 221 are constructed as an integral structure. This "integrated structure" design of the fastener 22 not only eliminates the connection step between the mounting portion 222 and the first snap-fit ​​portion 221, improving the overall installation efficiency of the flip cover 20, but also enhances the overall structural strength of the fastener 22, extending the service life of the flip cover 20.

[0068] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
