[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 3 A switching assembly 100 , a battery pack 1000 , and a vehicle according to an embodiment of the present invention are described.

[0030] like Figure 1 and Figure 2 As shown, the adapter assembly 100 according to the first embodiment of the utility model includes: an adapter bar 10, an insulating sleeve 20 and a protective cap 30.

[0031] Specifically, the adapter bar 10 has a first end 11 and a second end 12; the insulating sleeve 20 is sleeved on the adapter bar 10, and the first end 11 and the second end 12 are exposed outside the insulating sleeve 20; the protective cap 30 can be optionally arranged at the first end 11 and / or the second end 12 to wrap the first end 11 and / or the second end 12 and the fasteners arranged thereon.

[0032] It should be pointed out that one of the first end 11 and the second end 12 can be constructed as a plug-in end, and the other can be constructed as a bolt-fixed end fixed by a fastener, or the first end 11 and the second end 12 can both be constructed as bolt-fixed ends fixed by fasteners, and the plug-in end can be directly inserted into the connection end of the electrical equipment, the connector 300 or the output end of the power supply equipment without the need to provide a protective cap 30, and after the bolt-fixed end is assembled, the fastener and the bolt-fixed end (the first end 11 and / or the second end 12) are exposed to the outside, and when the electrical equipment or the power supply equipment is in the power-on state, there is a risk of electric shock, and the safety of use is low.

[0033] Based on this, the utility model provides a protective cap 30, and the protective cap 30 can be selectively arranged on the first end 11 and / or the second end 12 (that is, one end constructed as a bolt-fixed end). During the assembly of the adapter assembly 100, the first end 11 and / or the second end 12 can be exposed to facilitate the assembly between the adapter assembly 100 and surrounding components. After the assembly is completed, the protective cap 30 can be arranged on the first end 11 and / or the second end 12 to achieve shielding and protection of the first end 11 and / or the second end 12.

[0034] In some embodiments, the first end 11 is configured as a bolt-fixed end, and the protective cap 30 is disposed on the first end 11; in other embodiments, the second end 12 is configured as a bolt-fixed end, and the protective cap 30 is disposed on the second end 12; in other embodiments, both the first end 11 and the second end 12 are configured as bolt-fastened ends, and the protective cap 30 is disposed on the first end 11 and the second end 12.

[0035] According to the adapter assembly 100 of the embodiment of the utility model, by providing the protective cap 30, the protective cap 30 will not cause interference during the assembly process, thereby ensuring the assembly efficiency. After the assembly is completed, the protective cap 30 can effectively protect the exposed part of the adapter row 10, so as to improve the safety and reliability of the electrical equipment and energy storage device (such as the battery pack 1000) using the adapter assembly 100 of the utility model.

[0036] It can be understood that, in some embodiments, the protective cap 30 and the insulating sleeve 20 can be constructed as an integrally formed part, using the same or different materials. In other embodiments, the protective cap 30 and the insulating sleeve 20 can be constructed as separate parts, and the protective cap 30 can be detachably disposed on the first end 11 and / or the second end 12.

[0037] The adapter assembly 100 of the embodiment of the utility model is described in detail below with two specific embodiments.

[0038] In the first embodiment, the protective cap 30 and the insulating sleeve 20 are integrally formed.

[0039] like Figure 1 and Figure 2 As shown, the protective cap 30 is movably disposed on the adapter bar 10 to move along the extension direction of the adapter bar 10 .

[0040] That is to say, in the first embodiment, the protective cap 30 can be constructed as a sliding part and can be movably arranged outside the insulating sleeve 20, so that the first end 11 and / or the second end 12 can be exposed by sliding the protective cap 30 to avoid interference during the assembly process. After the assembly is completed, the protective cap 30 can be further moved to wrap the fixing part and the bolt tightening section.

[0041] Of course, the structure in which the protective cap 30 and the insulating sleeve 20 are integrally formed is not limited to this. In other embodiments, the protective cap 30 can be at least partially connected to the insulating sleeve 20 and can be flipped relative to the insulating sleeve 20 to switch between an avoidance position and a shielding position. In the avoidance position, the fastener and the first end 11 or the second end 12 can be avoided. In the shielding position, at least part of the fastener and the first end 11 or the second end 12 can be wrapped.

[0042] Furthermore, in an embodiment where the protective cap 30 is constructed as a sliding member, a flexible telescopic portion may be provided between the protective cap 30 and the insulating sleeve 20, and the protective cap 30 is suitable for adjusting the length of the flexible telescopic portion so that the protective cap 30 can selectively wrap the first end 11 and / or the second end 12 and the fasteners provided thereon.

[0043] In this way, not only the adjustment difficulty of the protective cap 30 can be reduced, but also the protective effect of the protective cap 30 in the wrapped state is better. In the second embodiment, the protective cap 30 and the insulating sleeve 20 are constructed as separate parts, and the protective cap 30 is detachably arranged at the first end 11 and / or the second end 12.

[0044] Therefore, during assembly, the protective cap 30 can be removed, and after the assembly is completed, the protective cap 30 can be installed on the first end 11 or the second end 12 .

[0045] Exemplarily, a snap-fit ​​or plug-in convex structure may be provided on the protective cap 30, and a corresponding card slot, plug-in concave or other matching structure may be provided on the shell or other structure to achieve the fixation of the protective cap 30, or a slot having the same shape as the fastener head (such as a bolt head) may be provided in the protective cap 30, and the fixation of the protective cap 30 may be achieved through interference fit, that is, the fixing structure of the protective cap 30. The present invention does not impose any specific restrictions, and those skilled in the art may make reasonable choices based on assembly requirements.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the protective cap 30 includes: a first sleeve portion 31 and a second sleeve portion 32, the cross-sectional size of the first sleeve portion 31 is larger than the cross-sectional size of the second sleeve portion 32, and the first sleeve portion 31 is suitable for accommodating the first end 11 and / or the second end 12 and the fasteners thereon, and the second sleeve portion 32 is suitable for accommodating the insulating sleeve 20.

[0047] Therefore, the first sleeve portion 31 with a larger size is used to accommodate the bolt fixing end and the fastener, which has lower assembly difficulty and better fixing effect, while the second sleeve portion 32 with a smaller size is used to accommodate the insulating sleeve 20. While improving the connection stability and reliability between the insulating sleeve 20 and the protective cap 30, the size difference between the first sleeve portion 31 and the second sleeve portion 32 can also be used to achieve limiting, thereby avoiding the protective cap 30 from shifting and improving the stability of the insulation protection.

[0048] Furthermore, the lower surface of the first sleeve portion 31 and the end of the second sleeve portion 32 away from the first sleeve portion 31 are both open.

[0049] Thus, the end of the second sleeve portion 32 is open, which facilitates the connection between the protective cap 30 and the insulating layer, and the lower surface of the first sleeve portion 31 is at least partially open to accommodate fasteners, which can also improve the convenience of installation and fixing of the protective cap 30 at the bolt fastening end.

[0050] According to some embodiments of the present invention, the adapter bar 10 is constructed as a flexible conductive metal bar. In this way, the adapter bar 10 can be bent according to the layout requirements to meet the layout requirements.

[0051] Exemplarily, the adapter assembly 100 is applied to the battery pack 1000, the first end 11 of the adapter bar 10 is electrically connected to the total output terminal of the battery module 200, and the second end 12 of the adapter bar 10 is electrically connected to the output plug-in terminal of the battery pack 1000 (that is, the high-voltage output terminal arranged on the body of the battery pack 1000). In order to avoid the second end 12 from being exposed, a protective cap 30 can be installed on the second end 12. At the same time, based on the positions of the output plug-in terminal and the total output terminal, the adapter bar 10 can be reasonably bent to reduce the difficulty of arranging the adapter assembly 100 and improve the convenience of arranging the adapter assembly 100.

[0052] like Figure 3 As shown, the battery pack 1000 according to the embodiment of the second aspect of the utility model includes: the adapter assembly 100 in the above embodiment.

[0053] According to the battery pack 1000 of the embodiment of the utility model, the above-mentioned adapter assembly 100 is used to improve the safety and reliability of the battery pack 1000 and effectively reduce the potential safety hazards of the battery pack 1000.

[0054] It should be pointed out that the battery pack 1000 in the embodiment of the present invention can be used as a power supply energy device for electrical equipment such as vehicles, and can also be formed into an energy storage device with other uses.

[0055] It is understandable that since the energy people need is highly temporal and spatial, in order to rationally use energy and improve energy utilization, it is necessary to use a medium or device to store one form of energy in the same form or convert it into another form of energy, and then release it in a specific form of energy based on future application needs. As we all know, to achieve the goal of carbon neutrality, green energy is currently mainly used to replace fossil energy to achieve the purpose of generating green electricity.

[0056] The current green energy mainly includes solar energy, wind energy, hydropower, etc. However, solar energy and wind energy generally have problems of strong intermittency and large volatility, which will cause unstable voltage of the green power grid (not enough electricity during peak hours and too much electricity during low hours). Unstable voltage will cause damage to electricity. Therefore, it may cause the problem of "wind and solar power abandonment" due to insufficient electricity demand or insufficient grid acceptance capacity.

[0057] To solve the problem of insufficient electricity demand or insufficient grid acceptance capacity, we must rely on energy storage devices. That is, the energy storage device converts electrical energy into other forms of energy through physical or chemical means and stores it, and then converts the energy stored in the energy storage device into electrical energy when needed. In simple terms, the energy storage device is similar to a large "power bank", which stores electrical energy when there is sufficient light energy and wind energy, and releases the stored electrical energy when needed.

[0058] At present, energy storage (i.e. energy storage) has a wide range of application scenarios, including power generation side energy storage, grid side energy storage, renewable energy grid-connected energy storage and user side energy storage. The corresponding types of energy storage devices include:

[0059] (1) Large energy storage containers used in grid-side energy storage scenarios can serve as high-quality active and reactive power regulation power sources in the grid, achieve load matching of electric energy in time and space, enhance the ability to absorb renewable energy, and are of great significance in grid system backup, relieving peak load power supply pressure, and peak and frequency regulation;

[0060] (2) The main operating mode of small and medium-sized energy storage cabinets used in industrial and commercial energy storage scenarios (banks, shopping malls, etc.) on the user side and small household energy storage boxes used in home energy storage scenarios on the user side is "peak shaving and valley filling". Since there is a large price difference in electricity charges at peak and valley locations according to electricity demand, after users have energy storage equipment, in order to reduce costs, they usually charge the energy storage cabinets / boxes during the low electricity price period; during the peak electricity price period, the electricity in the energy storage equipment is discharged for use to achieve the purpose of saving electricity bills. In addition, in remote areas and areas prone to natural disasters such as earthquakes and hurricanes, the existence of household energy storage devices is equivalent to users providing themselves and the power grid with backup power, eliminating the inconvenience caused by frequent power outages due to disasters or other reasons.

[0061] In combination with the above-mentioned situation of storing energy by physical or electrochemical means, taking electrochemical energy storage as an example, the energy storage device may include at least one group of chemical batteries, using the chemical elements in the chemical batteries as energy storage media, so as to realize the charging and discharging process through the chemical reaction or change of the energy storage medium. In simple terms, the electric energy generated by light energy and wind energy is stored in at least one group of chemical batteries through the chemical reaction or change of the energy storage medium, and when the use of external electric energy reaches a peak, the electric energy stored in at least one group of chemical batteries is released for use through the chemical reaction or change of the energy storage medium, or transferred to places where electric energy is scarce for use.

[0062] Furthermore, the battery pack 1000 and other structures and operations of the vehicle according to the embodiment of the present invention are known to ordinary technicians in the field and will not be described in detail here.
