Description

Technical Field

[0001] This utility model relates to the field of energy storage device technology, and more specifically, to a socket protection device and an energy storage device. Background Technology

[0002] Currently, balcony photovoltaic (PV) energy storage devices are receiving increasing attention as a core component of home energy storage systems, and their adoption rate is gradually increasing. In home settings, balcony PV energy storage devices can serve as emergency energy storage devices to cope with unexpected situations such as power outages. Furthermore, due to their portable design and large storage capacity, balcony PV energy storage devices can also play an indispensable role in outdoor settings.

[0003] In related technologies, balcony photovoltaic energy storage equipment includes a box or enclosure, which has a wiring port. Users can plug their electrical equipment into the wiring port to allow the balcony photovoltaic energy storage equipment to supply power to the equipment and meet their electricity needs.

[0004] For convenient electricity use, the wiring ports of photovoltaic energy storage devices on balconies are usually exposed, making them susceptible to the entry of rainwater, dust, and other impurities, posing safety hazards and making them difficult to clean. Utility Model Content

[0005] In order to solve or improve the technical problem that rainwater, dust and other impurities can easily enter the wiring port, posing a safety hazard and making it difficult to clean, one objective of this utility model is to provide a socket protection device.

[0006] Another objective of this invention is to provide an energy storage device having the aforementioned socket protection device.

[0007] To achieve the above objectives, the first aspect of this utility model provides a socket protection device for connection to the wiring port of an energy storage device. The socket protection device includes: a telescopic component capable of telescoping in a first direction, the telescopic component having an open wire groove; a protective cover connected to one end of the telescopic component; and a fixing part connected to the other end of the telescopic component, the fixing part being located at the wiring port. During the stretching of the protective cover away from the fixing part, the telescopic component gradually extends in the first direction, and the open wire groove gradually increases in size as the telescopic component extends. During the compression of the protective cover towards the fixing part, the telescopic component gradually compresses in the first direction, and the open wire groove gradually decreases in size as the telescopic component compresses.

[0008] In the technical solution defined by this utility model, by placing the socket protection device at the wiring port of the energy storage device, it can largely prevent rainwater, dust and other impurities from entering, which is beneficial to improving safety performance, reducing safety hazards, and also improving the cleanliness of the wiring port.

[0009] In addition, staff can stretch or compress the socket protection device according to actual needs (switching between the stretched and compressed states) to adjust the size of the opening cable tray. This design can largely prevent rainwater, dust and other impurities from entering without delaying wiring and cable routing, thereby improving safety performance and the cleanliness of the wiring port.

[0010] In some technical solutions, optionally, the telescopic component includes: a telescopic part for telescopic extension in a first direction, one end of which is connected to a fixed part; a folding part, one end of which is connected to the other end of the telescopic part, and the other end of which is connected to a protective cover; the telescopic part has a first placement cavity; when the socket protection device is in a compressed state, at least a portion of the folding part is located in the first placement cavity.

[0011] In this technical solution, when the socket protection device is in a compressed state, at least a portion of the folding part can be stored in the first placement cavity of the telescopic part. This design can significantly reduce the overall space occupied by the socket protection device in a compressed state and effectively prevent dust, liquid, foreign objects and other impurities from entering the socket.

[0012] During the process of stretching or compressing the socket protection device, the state of the telescopic and folding parts changes continuously, thereby adjusting the size of the opening cable tray to meet the usage requirements.

[0013] In some technical solutions, optionally, the telescopic part includes: at least two abutting parts, at least one abutting part is connected to the fixed part, and at least one abutting part is connected to the folding part; at least one first connecting part is connected to the abutting part; any two adjacent abutting parts are connected through the first connecting part; when the socket protection device is in a compressed state, any two adjacent abutting parts abut against each other.

[0014] In this technical solution, when the socket protection device is in a compressed state, any two adjacent abutting parts are tightly abutted together, so that the overall structure of the telescopic part is compact and the space occupied is effectively reduced; when the socket protection device is in an extended state, the adjacent abutting parts are separated from each other and maintain a stable distance under the support of the first connecting part, ensuring that the telescopic part has sufficient length.

[0015] By separating or bringing adjacent abutting parts closer together, the telescopic part gradually extends or compresses in the first direction, thereby adjusting the size of the opening groove to meet usage requirements.

[0016] In some technical solutions, optionally, the stiffness of the abutment portion is greater than the stiffness of the first connecting portion.

[0017] In this technical solution, when the user presses or pulls the protective cover, the first connecting part is more easily deformed than the abutting part, and adjacent abutting parts can move closer to or separate from each other, so that the telescopic part can be gradually compressed or extended in the first direction, ensuring that the telescopic part has a telescopic function.

[0018] In some technical solutions, the rigidity of the protective cover may optionally be greater than the rigidity of the folding portion.

[0019] In this technical solution, when the user presses or pulls the protective cover, the folded part is more easily deformed than the protective cover, so that the deformed folded part gradually enters the interior of the first placement cavity, or the folded part originally in the first placement cavity will gradually extend out, so that the telescopic component can be gradually compressed or extended in the first direction, ensuring that the telescopic component has a telescopic function.

[0020] In some technical solutions, optionally, the telescopic component further includes: a second connecting part disposed between the telescopic part and the folding part, one end of the second connecting part being connected to the end of the telescopic part away from the fixed part, and the other end of the second connecting part being connected to the end of the folding part away from the protective cover; when the socket protection device is in a compressed state, the folding part is located inside the second connecting part, and both the folding part and the second connecting part are located inside the first placement cavity.

[0021] In this technical solution, when the socket protection device is in a compressed state, the folding part can be stored in the second connecting part, and both the second connecting part and the folding part stored in the second connecting part are located in the first placement cavity of the telescopic part. This design method forms a multi-layer nested storage structure with the folding part, the second connecting part and the telescopic part, which is conducive to improving space utilization, significantly reducing the overall space occupied by the socket protection device in the compressed state, and effectively preventing dust, liquid, foreign objects and other impurities from entering the socket.

[0022] In some technical solutions, optionally, when the socket protection device is in the extended state, the protective cover, folding part, second connecting part, telescopic part, and fixing part are arranged sequentially in the first direction.

[0023] In this technical solution, when the socket protection device is in the extended state, the opening of the wire trough is at its maximum, allowing the wire harness to pass through and meet power requirements. The socket protection device can be stretched or compressed according to actual needs, thereby flexibly adjusting the size of the opening wire trough to meet usage requirements.

[0024] In some technical solutions, the stiffness of the second connecting part may be greater than that of the folding part.

[0025] In this technical solution, when the user presses the protective cover, the folding part is more easily deformed than the second connecting part. The second connecting part folds without deforming, or the second connecting part begins to deform only after the folding part has deformed, so that the deformed folding part gradually enters the interior of the second connecting part, and the second connecting part and the folding part enter the first placement cavity together to ensure that the telescopic component can retract smoothly.

[0026] The second aspect of this utility model provides an energy storage device, comprising: a housing, the housing having a wiring port; and a socket protection device as described in any of the above technical solutions, located at the wiring port.

[0027] Since the energy storage device includes any of the socket protection devices mentioned in the first aspect above, it has the beneficial effects of any of the above technical solutions, which will not be elaborated here.

[0028] In some technical solutions, optionally, the fixing part of the socket protection device extends into the box through the wiring port, and one side of the fixing part abuts against the inner wall of the box; the energy storage device also includes: a mounting plate, which is disposed in the box, and the mounting plate is disposed on the other side of the fixing part, and the mounting plate is connected to the fixing part and the box.

[0029] In this technical solution, when the mounting plate and the enclosure are connected, the socket protection device can be fixed at the wiring port position through the mutual cooperation between the mounting plate and the enclosure. When the mounting plate and the enclosure are not connected, the operator can remove the mounting plate and the socket protection device in sequence, so that the socket protection device is removed from the wiring port position. In addition, there is no need to set up a separate rigid structure in the fixing part, which helps to simplify the structure of the socket protection device.

[0030] Additional aspects and advantages of the present invention will become apparent in the following description or may be learned by practice of the present invention. Attached Figure Description

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, embodiments of the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] The following reference Figures 1 to 9 This invention describes a socket protection device and an energy storage device provided according to some embodiments of the present invention.

[0045] In one embodiment of the present invention, the socket protection device 100 is used to connect to the wiring port 211 of the energy storage device 200.

[0046] Optionally, the energy storage device 200 is a balcony photovoltaic energy storage device. It should be noted that the wiring port 211 of the energy storage device 200 is a socket, and this socket is an AC output socket. Users can plug their electrical equipment into the AC output socket to allow the energy storage device 200 to supply power to the electrical equipment and meet their electricity needs.

[0047] The socket protection device 100 of this utility model is used to protect the AC output socket of a photovoltaic energy storage device on a balcony. The AC output socket can output AC power to supply AC loads.

[0048] In some scenarios, such as power outages, the balcony photovoltaic energy storage device (energy storage device 200) can supply power to important loads (such as refrigerators) through this AC output socket. In other scenarios, users can also take the balcony photovoltaic energy storage device outdoors for use. Through this AC output socket, users can use some electrical appliances outdoors, such as kettles and air fryers.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the socket protection device 100 includes a telescopic assembly 110, a protective cover 130, and a fixing part 120. The telescopic assembly 110 is capable of telescopic movement in a first direction a, and the telescopic assembly 110 is provided with an open wire groove 160.

[0050] It should be noted that the open wire groove 160 is used for the wire harness to pass through. The wire harness is used to connect to the wiring port 211 (i.e., socket) of the energy storage device 200. During the stretching of the telescopic component 110 along the first direction a, the overall length of the telescopic component 110 increases, and the open wire groove 160 gradually increases; during the compression of the telescopic component 110 along the first direction a, the overall length of the telescopic component 110 decreases, and the open wire groove 160 gradually decreases.

[0051] Optionally, the first direction 'a' is the length direction of the socket protection device 100 (e.g., ...). Figure 1 , Figure 2 and Figure 3 (As shown).

[0052] The protective cover 130 is connected to one end of the telescopic assembly 110. The fixing part 120 is connected to the other end of the telescopic assembly 110. The fixing part 120 is located at the wiring port 211.

[0053] In other words, the telescopic component 110 is disposed between the protective cover 130 and the fixing part 120, and both ends of the telescopic component 110 are connected to the protective cover 130 and the fixing part 120 respectively.

[0054] Optionally, such as Figure 4 , Figure 5 , Figure 6and Figure 7 As shown, the energy storage device 200 includes a housing 210, and a wiring port 211 is provided on the housing 210. The fixing part 120 is detachably connected to the housing 210. When the fixing part 120 is connected to the housing 210, the socket protection device 100 is fixed at the position of the wiring port 211.

[0055] The fixing part 120 is detachably connected to the housing 210. This design makes it convenient for staff to disassemble and install the socket protection device 100, which is beneficial for maintenance or replacement.

[0056] In one specific embodiment, the fixing part 120 and the housing 210 are detachably connected by bolts, pins or other types of connectors, which is convenient, quick and easy to operate.

[0057] The socket protection device 100 has an extended state (e.g.) Figure 1 and Figure 2 (as shown) and compression state (as shown) Figure 3 (As shown). The socket protection device 100 can switch from an extended state to a compressed state to gradually reduce the size of the open wire groove 160; the socket protection device 100 can also switch from a compressed state to an extended state to gradually increase the size of the open wire groove 160.

[0058] The user presses or pulls the socket protection device 100 by the protective cover 130, meaning the protective cover 130 is usually subjected to pressing or pulling force. When the user presses the protective cover 130, the socket protection device 100 switches from an extended state to a compressed state; when the user pulls the protective cover 130, the socket protection device 100 switches from a compressed state to an extended state.

[0059] In addition, by setting the protective cover 130, the telescopic component 110 can be protected to a certain extent, which is conducive to improving the service life of the telescopic component 110.

[0060] As the protective cover 130 is stretched away from the fixing part 120, the telescopic component 110 gradually extends in the first direction a, and the opening groove 160 gradually increases in size as the telescopic component 110 extends. As the protective cover 130 is compressed towards the fixing part 120, the telescopic component 110 gradually compresses in the first direction a, and the opening groove 160 gradually decreases in size as the telescopic component 110 compresses.

[0061] In the technical solution defined by this utility model, by placing the socket protection device 100 at the wiring port 211 of the energy storage device 200, it can largely prevent rainwater, dust and other impurities from entering, which is beneficial to improving safety performance, reducing safety hazards, and also improving the cleanliness of the wiring port 211.

[0062] In addition, staff can stretch or compress the socket protection device 100 according to actual needs (switching between the stretched and compressed states) to adjust the size of the open wire groove 160. This design can largely prevent rainwater, dust and other impurities from entering without delaying wiring and cable routing, thereby improving safety performance and the cleanliness of the wiring port 211.

[0063] It should be emphasized that the socket protection device 100 of this utility model can be adapted to various types of wiring ports 211 (i.e., various types of sockets), has high versatility, and also has multiple functions such as waterproofing, rain protection, and dust protection.

[0064] In some embodiments, the telescopic component 110, the protective cover 130, and the fixing part 120 are optionally integrated into a single structure, meaning the socket protection device 100 is integrally injection molded. This design ensures sufficient connection strength between the components, reduces the number of parts, thereby reducing the number of assembly steps and improving assembly efficiency.

[0065] It should be noted that when the socket protection device 100 is integrally injection molded, the stiffness of corresponding positions within the socket protection device 100 can be adjusted by changing the thickness of the corresponding components. Stiffness refers to an object's ability to resist deformation when subjected to external forces. Objects with higher stiffness are less prone to deformation under stress and possess higher hardness and strength.

[0066] For example, by changing the thickness of the protective cover 130, the rigidity of the protective cover 130 can be adjusted; by changing the thickness of the fixing part 120, the rigidity of the fixing part 120 can be adjusted.

[0067] In one specific embodiment, the socket protection device 100 is made of rubber.

[0068] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the telescopic assembly 110 includes a telescopic part 111 and a folding part 112. The telescopic part 111 is used to extend and retract in a first direction a, and one end of the telescopic part 111 is connected to the fixing part 120. One end of the folding part 112 is connected to the other end of the telescopic part 111, and the other end of the folding part 112 is connected to the protective cover 130.

[0069] The folding part 112 is disposed between the telescopic part 111 and the protective cover 130, and both ends of the folding part 112 are connected to the telescopic part 111 and the protective cover 130 respectively. The telescopic part 111 is disposed between the folding part 112 and the fixing part 120, and both ends of the telescopic part 111 are connected to the folding part 112 and the fixing part 120 respectively.

[0070] The telescopic part 111 is provided with a first placement cavity 1111; when the socket protection device 100 is in a compressed state, at least a portion of the folding part 112 is provided in the first placement cavity 1111.

[0071] As the protective cover 130 is stretched away from the fixing part 120, the socket protection device 100 switches from a compressed state to an extended state. During this process, the telescopic part 111 gradually extends in the first direction a, and the overall length of the telescopic part 111 increases; the folded part 112, which was originally in the first placement cavity 1111, will gradually extend out.

[0072] When the socket protection device 100 is in the extended state, the protective cover 130, the folding part 112, the telescopic part 111, and the fixing part 120 are arranged sequentially in the first direction a.

[0073] As the protective cover 130 is compressed in the direction close to the fixing part 120, the socket protection device 100 switches from the extended state to the compressed state. During this process, the telescopic part 111 is gradually compressed in the first direction a, and the overall length of the telescopic part 111 decreases; the folding part 112 gradually enters the interior of the first placement cavity 1111.

[0074] When the socket protection device 100 is in a compressed state, at least a portion of the folding part 112 can be stored in the first placement cavity 1111 of the telescopic part 111. This design can significantly reduce the overall space occupied by the socket protection device 100 in a compressed state and effectively prevent dust, liquid, foreign objects and other impurities from entering the socket.

[0075] Optionally, the open cable tray 160 is provided in the telescopic part 111 and the folding part 112. During the process of stretching or compressing the socket protection device 100, the state of the telescopic part 111 and the folding part 112 changes continuously, thereby adjusting the size of the open cable tray 160 to meet the usage requirements.

[0076] It should be noted that when the socket protection device 100 is in a compressed state, the protective cover 130 and the telescopic part 111 may or may not abut against each other, and can be flexibly set according to the actual situation.

[0077] In one specific embodiment, when the socket protection device 100 is in a compressed state, the folding part 112 is completely inside the first placement cavity 1111, and at this time, the protective cover 130 abuts against the telescopic part 111. This design helps to improve the structural compactness of the socket protection device 100 in the compressed state. When the socket is not in use, switching the socket protection device 100 to the compressed state effectively prevents dust, liquids, foreign objects and other impurities from entering the socket.

[0078] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the telescopic portion 111 includes at least two abutting portions 1112 and at least one first connecting portion 1113. At least one abutting portion 1112 is connected to the fixing portion 120, and at least one abutting portion 1112 is connected to the folding portion 112. The first connecting portion 1113 is connected to the abutting portions 1112. Any two adjacent abutting portions 1112 are connected via the first connecting portion 1113. When the socket protection device 100 is in a compressed state, any two adjacent abutting portions 1112 abut against each other.

[0079] It should be emphasized that the number of abutting parts 1112 is at least two, that is, there can be two or more abutting parts 1112, and the number of abutting parts 1112 can be flexibly set according to actual needs. The number of first connecting parts 1113 is at least one, that is, there can be one, two or more first connecting parts 1113, and the number of first connecting parts 1113 can be flexibly set according to actual needs.

[0080] Each first connecting part 1113 is disposed between two adjacent abutting parts 1112, and one end of the first connecting part 1113 is connected to one of the abutting parts 1112, and the other end is connected to the other abutting part 1112.

[0081] As the protective cover 130 is stretched away from the fixing part 120, the socket protection device 100 switches from a compressed state to an extended state. During this process, the adjacent abutting parts 1112 separate from each other, and the telescopic part 111 gradually extends in the first direction a, increasing the overall length of the telescopic part 111.

[0082] As the protective cover 130 is compressed in the direction close to the fixing part 120, the socket protection device 100 switches from the extended state to the compressed state. During this process, any two adjacent abutting parts 1112 gradually move closer together, the telescopic part 111 is gradually compressed in the first direction a, and the overall length of the telescopic part 111 decreases.

[0083] When the socket protection device 100 is in the compressed state, any two adjacent abutting parts 1112 abut tightly together, so that the overall structure of the telescopic part 111 is compact and the space occupied is effectively reduced; when the socket protection device 100 is in the extended state, the adjacent abutting parts 1112 are separated from each other and maintain a stable distance under the support of the first connecting part 1113, ensuring that the telescopic part 111 has sufficient length.

[0084] By separating or bringing adjacent abutting portions 1112 closer to each other, the telescopic portion 111 gradually extends or compresses in the first direction a, thereby adjusting the size of the opening groove 160 to meet usage requirements.

[0085] In some embodiments, the stiffness of the abutment portion 1112 may be greater than the stiffness of the first connecting portion 1113.

[0086] When the socket protection device 100 is integrally injection molded, the rigidity of the abutment portion 1112 and the first connecting portion 1113 can be adjusted by changing the thickness of the abutment portion 1112 and the first connecting portion 1113. Optionally, the thickness of the abutment portion 1112 is greater than the thickness of the first connecting portion 1113.

[0087] It should be noted that stiffness refers to an object's ability to resist deformation when subjected to external forces.

[0088] The abutment portion 1112 is not easily deformed under external force, while the first connecting portion 1113 is more easily deformed under external force. Therefore, when the user presses or pulls the protective cover 130, the first connecting portion 1113 is more easily deformed than the abutment portion 1112, and adjacent abutment portions 1112 can move closer to or separate from each other, so that the telescopic portion 111 can gradually compress or extend in the first direction a, ensuring that the telescopic portion 111 has a telescopic function.

[0089] In addition, since the first connecting part 1113 is more easily deformed under external force, when the telescopic part 111 is subjected to external force, the first connecting part 1113 will deform first than the abutting part 1112. This design can reduce the installation difficulty of the socket protection device 100 to a certain extent, improve assembly efficiency, and also increase service life.

[0090] In some embodiments, the rigidity of the protective cover 130 may be greater than the rigidity of the fold 112.

[0091] When the socket protection device 100 is integrally injection molded, the rigidity of the protective cover 130 and the folding part 112 can be adjusted by changing their thicknesses. Optionally, the thickness of the protective cover 130 is greater than the thickness of the folding part 112.

[0092] The protective cover 130 is not easily deformed under external force, while the folding part 112 is more easily deformed under external force. Therefore, when the user presses or pulls the protective cover 130, the folding part 112 is more easily deformed than the protective cover 130, so that the deformed folding part 112 gradually enters the interior of the first placement cavity 1111, or the folding part 112 originally in the first placement cavity 1111 will gradually extend out, so that the telescopic component 110 can be gradually compressed or extended in the first direction a, ensuring that the telescopic component 110 has a telescopic function.

[0093] Furthermore, since the folding part 112 is more easily deformed under external force, when the socket protection device 100 is subjected to external force, the folding part 112 will deform first than the protective cover 130. This design ensures, on the one hand, that the telescopic component 110 has telescopic function and the protective cover 130 has pressing and pulling function; on the other hand, it can reduce the installation difficulty of the socket protection device 100 to a certain extent, improve assembly efficiency, and also increase service life.

[0094] In some embodiments, optionally, such as Figure 1 , Figure 2 and Figure 3 As shown, the telescopic assembly 110 also includes a second connecting portion 113. The second connecting portion 113 is disposed between the telescopic portion 111 and the folding portion 112. One end of the second connecting portion 113 is connected to the end of the telescopic portion 111 away from the fixing portion 120, and the other end of the second connecting portion 113 is connected to the end of the folding portion 112 away from the protective cover 130.

[0095] When the socket protection device 100 is in a compressed state, the folding part 112 is located inside the second connecting part 113, and both the folding part 112 and the second connecting part 113 are located inside the first placement cavity 1111.

[0096] It should be noted that the first placement cavity 1111 provides storage space for the second connecting part 113 and the folding part 112 housed in the second connecting part 113.

[0097] When the socket protection device 100 is in a compressed state, the folding part 112 can be stored in the second connecting part 113. The second connecting part 113 and the folding part 112 stored in the second connecting part 113 are both located in the first placement cavity 1111 of the telescopic part 111. This design forms a multi-layer nested storage structure with the folding part 112, the second connecting part 113 and the telescopic part 111, which helps to improve space utilization, significantly reduces the overall space occupied by the socket protection device 100 in the compressed state, and effectively prevents dust, liquids, foreign objects and other impurities from entering the socket.

[0098] It should be noted that in the folded state (compressed state), the second connecting part 113 wraps around the folded part 112, forming a double protective barrier with the first placement cavity 1111 of the telescopic part 111. This effectively prevents impurities such as dust and liquid from entering, avoids damage to the folded part 112 due to external factors, and thus extends the service life of the folded part 112. In the extended state, the second connecting part 113 can also work with the telescopic part 111 and the folded part 112 to cover the wiring port 211, improving the protective effect.

[0099] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, when the socket protection device 100 is in the extended state, the protective cover 130, the folding part 112, the second connecting part 113, the telescopic part 111, and the fixing part 120 are arranged sequentially in the first direction a.

[0100] Optionally, an open cable tray 160 is provided in the folding portion 112, the second connecting portion 113, and the telescopic portion 111. When the socket protection device 100 is in the extended state, the open cable tray 160 is at its maximum size, allowing the wire harness to pass through to meet power demand.

[0101] The socket protection device 100 can be stretched or compressed according to actual needs, thereby flexibly adjusting the size of the open wire groove 160 to meet usage requirements. Users only need to press or pull the protective cover 130, making the operation simple and quick.

[0102] In some embodiments, the stiffness of the second connecting portion 113 is optionally greater than the stiffness of the folding portion 112.

[0103] When the socket protection device 100 is integrally injection molded, the rigidity of the second connecting part 113 and the folding part 112 can be adjusted by changing their thicknesses. Optionally, the thickness of the second connecting part 113 is greater than the thickness of the folding part 112.

[0104] The second connecting portion 113 is less prone to deformation under external force, while the folding portion 112 is more prone to deformation under external force. In other words, when the telescopic assembly 110 is subjected to external force, the folding portion 112 will deform before the second connecting portion 113. Therefore, when the user presses the protective cover 130, the folding portion 112 is more prone to deformation than the second connecting portion 113. The second connecting portion 113 is either folded (so that it can be stored in the first placement cavity 1111) without deformation, or the second connecting portion 113 begins to deform only after the folding portion 112 has deformed, so that the deformed folding portion 112 gradually enters the interior of the second connecting portion 113, and the second connecting portion 113 and the folding portion 112 enter the first placement cavity 1111 together, to ensure that the telescopic assembly 110 can retract smoothly.

[0105] It should be emphasized that since the second connecting part 113 is folded (so that it can be stored in the first placement cavity 1111) without deformation, or the second connecting part 113 begins to deform only after the folding part 112 has deformed, it can be ensured that the deformed folding part 112 enters the interior of the second connecting part 113 first, and then the second connecting part 113 and the folding part 112 enter the first placement cavity 1111 together.

[0106] In one embodiment according to the present invention, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the energy storage device 200 includes a housing 210 and a socket protection device 100 as described in any of the above embodiments. The housing 210 has a wiring port 211. The socket protection device 100 is located at the wiring port 211.

[0107] The fixing part 120 is detachably connected to the housing 210. When the fixing part 120 and the housing 210 are connected, the socket protection device 100 is fixed at the position of the wiring port 211.

[0108] The fixing part 120 is detachably connected to the housing 210. This design makes it convenient for staff to disassemble and install the socket protection device 100, which is beneficial for maintenance or replacement.

[0109] In one specific embodiment, the fixing part 120 and the housing 210 are detachably connected by bolts, pins or other types of connectors, which is convenient, quick and easy to operate.

[0110] Since the energy storage device 200 includes the socket protection device 100 in any of the above embodiments, it has the beneficial effects of any of the above embodiments, which will not be repeated here.

[0111] Optionally, the energy storage device 200 is a balcony photovoltaic energy storage device. The connection port 211 of the energy storage device 200 is a socket, and this socket is an AC output socket. Users can plug their electrical equipment into the AC output socket to allow the energy storage device 200 to supply power to the electrical equipment and meet their electricity needs.

[0112] The socket protection device 100 of this utility model is used to protect the AC output socket of a photovoltaic energy storage device on a balcony. The AC output socket can output AC power to supply AC loads.

[0113] In some scenarios, such as power outages, the balcony photovoltaic energy storage device (energy storage device 200) can supply power to important loads (such as refrigerators) through this AC output socket. In other scenarios, users can also take the balcony photovoltaic energy storage device outdoors for use. Through this AC output socket, users can use some electrical appliances outdoors, such as kettles and air fryers.

[0114] In some embodiments, optionally, the fixing part 120 of the socket protection device 100 extends into the housing 210 through the wiring port 211. One side of the fixing part 120 abuts against the inner wall of the housing 210. Figure 6 , Figure 8 and Figure 9 As shown, the energy storage device 200 also includes a mounting plate 220, which is disposed inside the housing 210 and on the other side of the fixing part 120. In other words, the fixing part 120 of the socket protection device 100 is disposed between the inner wall of the housing 210 and the mounting plate 220, and both sides of the fixing part 120 abut against the inner wall of the housing 210 and the mounting plate 220, respectively.

[0115] The mounting plate 220 is connected to the fixing part 120 and the housing 210 to fix the socket protection device 100 at the position of the wiring port 211.

[0116] Optionally, the mounting plate 220 and the housing 210 are detachably connected, facilitating the installation and removal of the mounting plate 220 by operators. When the mounting plate 220 and the housing 210 are connected, the socket protection device 100 can be fixed at the wiring port 211 through their mutual cooperation. When the mounting plate 220 and the housing 210 are not connected, operators can remove the mounting plate 220 and the socket protection device 100 in sequence, so that the socket protection device 100 is removed from the wiring port 211.

[0117] Optionally, the mounting plate 220 and the housing 210 can be detachably connected by bolts, pins, or other types of connectors, which is convenient, quick, and easy to operate. The connector passes through the mounting plate 220, the fixing part 120, and the housing 210 in sequence, or through the housing 210, the fixing part 120, and the mounting plate 220 in sequence, to fix the socket protection device 100 at the position of the wiring port 211.

[0118] In one specific embodiment, the mounting plate 220 is provided with a plurality of first connecting holes, the fixing part 120 is provided with a plurality of second connecting holes, and the housing 210 is provided with a plurality of third connecting holes. The positions and numbers of the first connecting holes, second connecting holes, and third connecting holes are arranged accordingly.

[0119] The connector passes through the first connection hole, the second connection hole and the third connection hole in sequence, or through the third connection hole, the second connection hole and the first connection hole in sequence, to fix the socket protection device 100 at the position of the wiring port 211.

[0120] It should be noted that the mounting plate 220 and the housing 210 are rigid structures, while the fixing part 120 is a flexible structure (the rigidity of the mounting plate 220 is greater than that of the fixing part 120; the rigidity of the housing 210 is greater than that of the fixing part 120). Rigidity refers to an object's ability to resist deformation when subjected to external forces. Objects with higher rigidity are less prone to deformation under stress and possess higher hardness and strength.

[0121] This design ensures the connection strength between the fixing part 120 and the housing 210, and largely prevents the fixing part 120 from detaching from the housing 210. Furthermore, it eliminates the need for a separate rigid structure within the fixing part 120, simplifying the structure of the socket protection device 100.
