Description

Technical Field

[0001] The utility model relates to the technical field of fuses, and in particular to a fuse assembly and an energy storage container. Background Art

[0002] Fuses in energy storage containers are important safety devices, automatically shutting off current in the event of an abnormal circuit condition, protecting the safe operation of the circuit and equipment. Currently, fuses rated for 1500V are used on the DC side of power storage container systems. However, due to the small and fragile diameter of the fuse element, excessive vibration during transportation or accidental dropping during installation can damage the narrow diameter. Damage to the narrow diameter can alter the current-carrying capacity and interrupting capability of the fuse, potentially leading to failure. Therefore, determining whether a fuse has been subjected to shock before installation and use can provide a better understanding of its safety and reliability. Utility Model Content

[0027] Below, with reference to the accompanying drawings, the preferred embodiments of the present application are described in detail. In the following description, the same symbols are given to the same components, and repeated descriptions are omitted. In addition, the accompanying drawings are only schematic diagrams, and the ratio of the dimensions of the components to each other or the shapes of the components may be different from the actual ones. It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0028] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0029] Reference Figures 1 to 3 The present application provides a fuse assembly comprising a fuse 1 and a shock recorder 2. The fuse 1 comprises a housing 11 and a connection terminal 12. The connection terminal 12 is disposed through the housing 11 and is configured to connect to a corresponding circuit. The fuse 1 is configured to cut off current when a circuit fault occurs. The shock recorder 2 is connected to the surface of the housing 11 and is staggered with the connection terminal 12. The shock recorder 2 is configured to record data of external shocks to the fuse 1.

[0030] Once activated, the impact recorder 2 records the impact data experienced by the fuse 1. Before installing the fuse 1, workers can review the recorded impact data to determine whether the fuse 1 has previously been subjected to significant impact or multiple impacts. This allows them to select a fuse 1 with a higher safety factor, providing a reference. This ensures the safety of the equipment using the fuse 1. Furthermore, the impact recorder 2 is mounted on the surface of the housing 11, without affecting the connection between the connection terminal 12 and the external circuit, nor the normal operation of the fuse 1.

[0031] It is understandable that, since the connection end 12 needs to be connected to an external circuit, the impact recorder 2 and the connection end 12 are staggered in this application so as not to affect the connection between the connection end 12 and the external circuit. Figure 1 The shell 11 includes two end portions 112 arranged opposite to each other, each end portion 112 is provided with a connecting end 12, and the connecting end portion is located outside the shell 11. When the fuse 1 is connected to an external circuit, the portion of the connecting end 12 facing away from the shell 11 is connected to the external circuit. Since the impact recorder 2 is mounted on the surface of the shell 11, the connection between the connecting end 12 and the external circuit is not affected. On the contrary, if the impact recorder 2 and the connecting end 12 are not staggered, for example, if the impact recorder 2 and the connecting end 12 are located at the same end of the shell 11, it will hinder the connection of the connecting end 12 to the external circuit, affecting the normal use of the fuse 1.

[0032] In some embodiments, the impact recorder 2 can be powered by its internal battery. After the impact recorder 2 is installed on the surface of the fuse 1 housing 11, the staff can activate the impact recorder 2, such as by activating the impact recorder 2 through a card reader, and the impact recorder 2 can begin to record the impact data received. When it is necessary to view the data, the staff can connect the impact recorder to an external device such as a mobile phone or computer via Bluetooth or Wi-Fi. Taking a mobile phone as an example, download the APP corresponding to the impact recorder 2. After the impact recorder 2 is connected to the mobile phone, the data recorded by the impact recorder 2 can be synchronized to the APP. The staff can view the frequency, size, occurrence time and other information of the impact events recorded by the impact recorder 2 in the APP.

[0033] In the related art, the impact conditions to which the fuse is subjected cannot usually be effectively monitored from the time the fuse leaves the factory until it is installed and used. If a fuse that has been subjected to a large impact is installed and its internal narrow diameter is severely damaged, it may erroneously disconnect the circuit even in normal operation, thereby reducing the ability to protect the circuit and equipment, or failing to effectively limit the current, which may cause circuit overload and even cause fire, equipment damage or other safety accidents. Therefore, the fuse assembly involved in this application can activate the impact recorder 2 after the fuse assembly leaves the factory, so as to better monitor whether the fuse 1 has been subjected to a large impact, thereby providing a reference for the staff to select a fuse 1 with a higher safety factor. As a result, the equipment using the fuse 1 can also be fully protected.

[0034] Of course, the impact recorder 2 can continue to monitor data even after the fuse assembly is installed in an external device. For example, after the fuse assembly is installed in an energy storage container, the impact recorder 2 can continue to monitor impact and vibration data during the container's transportation. The impact recorder 2 typically also monitors temperature and humidity, providing a reference for staff to monitor the equipment's operating environment.

[0035] In some embodiments, the housing 11 includes two oppositely disposed end portions 112 and a main body 111 disposed between the end portions 112. A connection terminal 12 is provided through each end portion 112, and the shock recorder 2 is disposed on a surface of the main body 111. Thus, after the shock recorder 2 is installed, it does not interfere with the connection between the connection terminal 12 and the external circuit, nor does it affect the normal use of the fuse 1.

[0036] In some embodiments, reference Figure 1The fuse 1 also includes an indicator 13, which is used to indicate the working status of the fuse 1; the cross-section of the main body 111 is a square structure; the main body 111 includes two side walls that are adjacently or oppositely arranged, the indicator 13 is arranged on one side wall, and the impact recorder 2 is arranged on the other side wall. Among them, the indicator 13 will send a signal when the fuse 1 trips. Therefore, placing the impact recorder 2 and the indicator 13 on two different sides can facilitate the staff to observe the indicator 13 and ensure that the operator can quickly identify potential safety problems. Of course, when the fuse 1 does not trip, the indicator 13 can also send another signal to prompt the fuse 1 to be in a normal working state.

[0037] In some examples, when the fuse 1 trips, the indicator 13 pops up to provide an obvious visual signal, which helps operators to promptly detect and deal with potential electrical problems and ensure the safe operation of the equipment.

[0038] Reference Figure 3 In some embodiments, the housing 11 includes a main body 111, and the connection end 12 is provided through the main body 111; the housing 11 also includes a heat sink 114, which is protruding from the main body 111, and the impact recorder 2 is connected to the surface of the heat sink 114 on the side away from the main body 111; the heat sink 114 is provided with a heat dissipation space 115, and the heat dissipation space 115 passes through the impact recorder 2. Specifically, it can be understood that a portion of the impact recorder 2 is connected to the surface of the heat sink 114, and another portion of the impact recorder 2 is separated from the main body 111 by the heat dissipation space 115. Therefore, by providing the heat dissipation space 115, a portion of the impact recorder 2 is not directly connected to the main body 111, which helps to reduce the situation where heat dissipation of the fuse 1 is blocked during use.

[0039] Generally, the fuse 1 generates a certain amount of heat during operation, and the heat sink 114 in this embodiment can help dissipate the heat by forming a heat dissipation space 115, so that the fuse 1 component can continue to be used after being installed on an external device to monitor data through the impact recorder 2. There is no need to worry about the impact recorder 2 affecting the heat dissipation of the fuse 1 and to remove the impact recorder 2.

[0040] Reference Figure 4In some embodiments, the heat sink 114 further includes a plurality of heat dissipation portions 116 , with a heat dissipation space 115 formed between adjacent heat dissipation portions 116 . The heat dissipation space 115 communicates with the external space along the length or height of the fuse 1 . Thus, the heat dissipation space 115 can have a channel-like structure and can extend through the length or height of the fuse 1 , thereby forming a ventilation channel within the heat dissipation space 115 , helping to dissipate heat from the fuse 1 to the outside through air convection, resulting in a better heat dissipation effect.

[0041] In some examples, the heat sink may be integrally formed with the main body.

[0042] In some embodiments, the fuse assembly may further include a colloid positioned between the impact recorder 2 and the housing 11 to connect the two devices. This method of connecting the impact recorder 2 to the housing 11 via the colloid is simple to operate and improves installation efficiency. Furthermore, the colloid connection is stable and durable, capable of withstanding prolonged use and repeated impacts, ensuring safety and reliability.

[0043] In some examples, the colloid may be double-sided tape, with both sides of the tape connected to the shock recorder 2 and fuse 1, respectively. In some examples, the colloid may be 3M double-sided tape. 3M double-sided tape has excellent adhesion, can firmly adhere to various materials, and can maintain adhesion for a long time. 3M double-sided tape can also maintain stable adhesion in high-temperature environments. In other examples, the colloid may be glue applied to the shock recorder 2 or fuse 1.

[0044] The thickness of the colloid can be between 0.5 mm and 1 mm. For example, the thickness can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, or 1 mm. Colloids within this thickness range can adapt to certain thermal expansion and contraction, providing a stronger bond. Conversely, colloids that are too thin are prone to bond breakage due to temperature fluctuations or large vibrations, while colloids that are too thick can waste material and hinder cost control.

[0045] In some other embodiments, the impact recorder 2 and the housing 11 may be connected together in other ways, such as by snap connection, welding, hot melting, etc.

[0046] In some embodiments, reference Figure 5The impact recorder 2 includes a mounting surface 21 facing the housing 11. The mounting surface 21 includes a coating area 211 for applying the colloid. The coating area 211 is located in the center of the mounting surface 21. The colloid coating area 211 is located in the center of the mounting surface 21, thereby ensuring that the impact force is evenly distributed on the impact recorder 2, thereby improving the overall impact resistance and preventing the impact recorder 2 from falling.

[0047] As an embodiment, the ratio of the area of the coating area 211 to the area of the mounting surface 21 is between 50% and 80%. This prevents the colloid from completely covering the mounting surface 21, and the colloid coating area 211 is located in the center of the mounting surface 21. This allows the colloid to maintain a distance from the edge of the mounting surface 21. This prevents the colloid from sticking to external objects and reduces damage to the colloid from external dust, moisture, and the like, thereby improving its durability. Furthermore, this configuration saves material and reduces costs.

[0048] In some examples, the ratio of the area of the coating region 211 to the area of the mounting surface 21 may be 50%, 60%, 65%, 70%, or 80%.

[0049] In some embodiments, reference Figure 6 and Figure 7 The surface includes an installation area 113, which is the orthographic projection area of the impact recorder 2 on the surface; the housing 11 is provided with a positioning protrusion, which is arranged around the edge of the installation area 113. It can be understood that since the installation area 113 is the orthographic projection area of the impact recorder 2 on the surface, the positioning protrusion arranged around the edge of the installation area 113 also surrounds the impact recorder 2. As a result, the side of the positioning protrusion will abut against the outer wall of the impact recorder 2, and the positioning protrusion can limit the impact recorder 2 on the circumferential side, thereby improving the stability of the connection between the impact recorder 2 and the fuse 1. In addition, when the staff connects the impact recorder 2 and the fuse 1, the positioning protrusion can also play a guiding role to prevent the position of the impact recorder 2 from deviating from the preset position during installation.

[0050] In some examples, the positioning protrusion is integrally formed with the housing 11 , and the positioning protrusion is firmly connected to the housing 11 .

[0051] In some examples, the contact area between the positioning protrusion and the impact recorder 2 may also be connected via a colloid, thereby improving the reliability of the connection between the impact recorder 2 and the fuse 1 .

[0052] As an embodiment, the housing 11 is provided with a positioning groove, the impact recorder 2 is accommodated in the positioning groove, and the side wall of the positioning groove abuts against the impact recorder 2. Specifically, the positioning groove is provided on the housing 11 and is a recessed space on the housing 11. As a result, the side of the positioning groove abuts against the outer wall of the impact recorder 2, and the positioning groove can also limit the impact recorder 2 on the circumferential side, thereby improving the stability of the connection between the impact recorder 2 and the fuse 1. In addition, when the staff connects the impact recorder 2 and the fuse 1, the positioning groove can also play a guiding role, preventing the impact recorder 2 from deviating from the preset position during installation.

[0053] In some embodiments, the impact recorder 2 is provided with a first connection hole, and the fuse 1 is provided with a second connection hole corresponding to the position of the first connection hole. The first connection hole and the second connection hole are connected by screws so that the impact recorder 2 is connected to the housing 11. Thus, the impact recorder 2 and the fuse 1 can be threadedly connected. The threaded connection method can provide a strong fixing effect, ensuring that the impact recorder 2 and the fuse 1 can maintain a stable connection when subjected to impact and will not fall off due to vibration or impact. In addition, when the fuse 1 needs to be replaced, the threaded connection method can quickly disassemble and separate the two, and the operation is convenient and quick.

[0054] In some examples, four first connection holes may be provided and evenly distributed on the housing of the shock recorder 2. This can make the shock recorder 2 and the fuse 1 more stable when connected, reducing accidental falling off or damage caused by unstable center of gravity or loose connection.

[0055] This application also provides an energy storage container, which includes the fuse assembly described above. In some examples, the connection end 12 of the fuse assembly is connected to a cable within the energy storage container to connect the fuse assembly to the circuit of the energy storage container. The fuse assembly can be connected to the battery pack of the energy storage container to protect the battery pack from damage caused by excessive current. The fuse assembly can also be connected to a DC busbar to protect the entire battery pack from faults.

[0056] In summary, the fuse assembly involved in the application includes a fuse 1 and an impact recorder 2, wherein the fuse 1 includes a shell 11 and a connection end 12, the connection end 12 is provided through the shell 11, the impact recorder is connected to the surface of the shell 11 and is staggered with the connection end 12, and the impact recorder 2 is used to record data of external impacts on the fuse 1. In this way, the impact recorder 2 can record the impact data of the fuse 1 after activation. Before installing the fuse 1, the staff can check the recorded impact data to determine whether the fuse 1 has been subjected to a large impact or multiple impacts before, and then use it as a reference for the staff to select a fuse 1 with a higher safety factor. As a result, the equipment using the fuse 1 can also be fully guaranteed to be safe. In addition, the impact recorder 2 is staggered with the connection end 12, which will not affect the connection between the connection end 12 and the external circuit, and can ensure the normal use of the fuse 1.
