[0062] Next, reference is made to Figures 1 - 10 to describe the battery pack 1000 according to an embodiment of the present utility model.

[0063] As Figure 1 shown, the battery pack 1000 according to an embodiment of the present utility model includes a side beam 300, a battery cell assembly, a power distribution box 400, and an adapter structure 100.

[0064] Specifically, as Figure 1 and Figure 2 shown, the side beam 300 extends along a first direction (such as the first direction shown in Figure 1 ), a receiving cavity is defined inside the side beam 300, and the battery cell assembly is disposed in the side beam 300 along a second direction (such as Figure 1The first direction and the second direction are perpendicular to each other. The distribution box 400 is arranged in the accommodating cavity. The side beam 300 can protect the distribution box 400 when the battery cell assembly has thermal runaway. The side beam 300 can block the smoke and high-temperature gas generated when the battery cell assembly has thermal runaway, so as to prevent the thermal runaway from being transmitted to the distribution box 400.

[0065] In the prior art, the battery cell assembly and the distribution box 400 are electrically connected inside the side beam, and the installation depth of the electrical connection between the battery cell assembly and the distribution box 400 is relatively large. The installation personnel may have difficulty in operating the electrical connection between the battery cell assembly and the distribution box 400 due to viewing angle reasons.

[0066] like Figure 1 As shown, a groove 301 is provided on the side of the side beam 300 facing the battery cell assembly, and the groove 301 is arranged opposite to the distribution box 400. At least a part of the adapter structure 100 is arranged in the groove 301 for electrically connecting the battery cell assembly and the distribution box 400. The adapter structure 100 can be arranged in the groove 301 which is easy for the installer to observe, so that the electrical connection process between the battery cell assembly and the distribution box 400 can be within the field of view of the installer, making the electrical connection operation between the battery cell assembly and the distribution box 400 relatively simple.

[0067] According to the battery pack 1000 of the embodiment of the utility model, the distribution box 400 is arranged in the accommodating cavity of the side beam 300, the battery cell assembly is arranged on one side of the side beam 300 along the second direction, and a groove 301 is provided on the side of the side beam 300 facing the battery cell assembly, and the groove 301 is arranged opposite to the distribution box 400. At least a part of the adapter structure 100 is arranged in the groove 301. The adapter structure 100 can be arranged in the groove 301 which is easy for the installer to observe. The electrical connection process between the battery cell assembly and the distribution box 400 can be within the field of view of the installer, so that the electrical connection operation between the battery cell assembly and the distribution box 400 is relatively simple.

[0068] In some embodiments of the present invention, Figure 8 and Figure 9 As shown, the adapter structure 100 includes a first mounting bracket 1 and an adapter assembly 2. The first mounting bracket 1 is an insulating member. The first mounting bracket 1 includes a mounting portion 121. The mounting portion 121 is disposed in the groove 301. The adapter assembly 2 is overlapped on the mounting portion 121 along the third direction (such as Figure 2 On one side of the third direction shown in the figure, the first direction, the second direction and the third direction are perpendicular to each other.

[0069] That is to say, the transfer component 2 can be electrically connected between the battery cell component and the distribution box 400. Since the transfer component 2 has the function of electrical connection, the transfer component 2 is a live structure. By installing the transfer component 2 on the installation part 121 of the first installation bracket 1, the position of the transfer structure 100 can be fixed better, so that the transfer structure 100 is stably electrically connected between the battery cell component and the distribution box 400. In addition, the first installation bracket 1 with insulating performance can also insulate the transfer component 2 better, avoiding short circuit after the transfer component 2 contacts other component structures in the battery box.

[0070] At the same time, the installation part 121 is arranged in the groove 301, and the transfer component 2 is arranged on one side of the installation part 121 along the third direction. At this time, the transfer component 2 is arranged at one end of the installation part 121 in the third direction, and the battery cell component and the distribution box 400 are connected to one end of the installation part 121 in the third direction close to the installer, making the electrical connection operation between the battery cell component and the distribution box 400 relatively simple.

[0071] In some embodiments of the present invention, such as Figure 8 and Figure 9 shown, the transfer component 2 includes a first transfer component 21 and a second transfer component 22. The first transfer component 21 is electrically connected between the first output pole of the battery cell component and the first input pole of the distribution box 400; the second transfer component 22 is electrically connected between the second output pole of the battery cell component and the second input pole of the distribution box 400.

[0072] It can be understood that the first output pole is the positive pole of the battery cell component, the second output pole is the negative pole of the battery cell component, the first input pole is the positive pole of the distribution box 400, the second input pole is the negative pole of the distribution box 400. The first transfer component 21 can connect the positive pole of the battery cell component and the positive pole of the distribution box 400, and the second transfer component 22 can connect the negative pole of the battery cell component and the negative pole of the distribution box 400, realizing the electrical connection between the battery cell component and the distribution box 400.

[0073] The first transfer component 21 and the second transfer component 22 are installed at one end of the installation part 121 along the third direction, and the battery cell component and the distribution box 400 are connected to one end of the installation part 121 in the third direction close to the installer, making the electrical connection operation between the battery cell component and the distribution box 400 relatively simple.

[0074] In some embodiments of the present invention, such as Figure 8As shown, the adapter structure 100 further includes a second mounting bracket 5. The second mounting bracket 5 is disposed on the side of the mounting portion 121 close to the distribution box 400, and the second mounting bracket 5 is connected to the distribution box 400. Both the second bending member 212 and the fourth bending member 222 are mounted on the second mounting bracket 5 and separated by the second mounting bracket 5. The second bending member 212 and the fourth bending member 222 that are bent and arranged on the second mounting bracket 5 can preferably optimize the circuit layout and effectively save the installation space. Moreover, the second bending member 212 and the fourth bending member 222 are spaced apart. The second mounting bracket 5 is an insulating member, which can prevent the first adapter assembly 21 from contacting the second adapter assembly 22 to cause a short circuit, and can prevent a short circuit in the electrical connection between the battery cell assembly and the distribution box 400.

[0075] In some embodiments of the present invention, as Figure 8 and Figure 9 shown, the first adapter assembly 21 includes a first bending member 211 and a second bending member 212 that are electrically connected on the mounting portion 121. The first bending member 211 is electrically connected to the first output pole of the battery cell assembly, and the second bending member 212 is electrically connected to the first input pole of the distribution box 400. The second adapter assembly 22 includes a third bending member 221 and a fourth bending member 222 that are electrically connected on the mounting portion 121. The third bending member 221 is electrically connected to the second output pole of the battery cell assembly, and the fourth bending member 222 is electrically connected to the second input pole of the distribution box 400. During the assembly process of the battery pack 1000, the first bending member 211 and the first output pole of the battery cell assembly can be assembled together first, and the third bending member 221 and the second output pole of the battery cell assembly can be assembled together. Then, the second bending member 212 and the first input pole of the distribution box 400 and the fourth bending member 222 and the second input pole of the distribution box 400 can be assembled together. Finally, the electrical connection between the distribution box 400 and the battery cell assembly is realized through the connection between the first bending member 211 and the second bending member 212 and the connection between the third bending member 221 and the fourth bending member 222, making the electrical connection between the distribution box 400 and the battery cell assembly more convenient and reliable.

The other end of the first part 2121 is connected to the upper end of the second part 2122. The negative copper busbar of the distribution box includes a first piece 2221 disposed on the lower end face of the second mounting bracket 5, a second piece 2222 disposed on the front end face of the second mounting bracket 5, a third piece 2223 disposed on the rear end face of the second mounting bracket 5, and a fourth piece 2224 disposed on the top surface of the mounting portion 121. The second piece 2222 is bent in an "L" shape and is connected to the lower end of the first piece 2221 and the lower end of the third piece 2223 at both ends. The upper end of the third piece 2223 is connected to the fourth piece 2224. Moreover, the second part 2122 of the positive copper busbar of the distribution box 400 and the first piece 2221 of the negative copper busbar of the distribution box 400 are spaced apart on the front end face of the second mounting bracket 5. Thus, by making both the positive copper busbar of the distribution box 400 and the negative copper busbar of the distribution box 400 have a bent structure, the positive copper busbar of the distribution box 400 and the negative copper busbar of the distribution box 400 can be better arranged, which is conducive to the orderly connection of the circuit and can save space. In addition, the positive copper busbar of the distribution box 400 and the negative copper busbar of the distribution box 400 can be better separated and fixed on the second mounting bracket 5, and it is also conducive to both the positive copper busbar of the distribution box 400 and the negative copper busbar of the distribution box 400 being fixedly connected to the upper end face of the mounting portion 121.

[0079] In some embodiments of the present invention, along the second direction, one end of the first bending member 211 is placed on the free end face of the mounting portion 121 along the third direction, and the other end of the first bending member 211 extends along the third direction and is electrically connected to the first output pole; along the second direction, one end of the second bending member 212 is placed on the free end face of the mounting portion 121 along the third direction and is electrically connected to the first bending member 211, and the other end of the second bending member 212 extends along the third direction and is electrically connected to the first input pole; along the second direction, one end of the third bending member 221 is placed on the free end face of the mounting portion 121 along the third direction, and the other end of the third bending member 221 extends along the third direction and is electrically connected to the second output pole; along the second direction, one end of the fourth bending member 222 is placed on the free end face of the mounting portion 121 along the third direction and is electrically connected to the third bending member 221, and the other end of the fourth bending member 222 extends along the third direction and is electrically connected to the second input pole.

[0080] It can be understood that during the assembly process of the battery pack 1000, the first bent part 211 and the first output pole of the battery cell assembly can be assembled together first, and the third bent part 221 and the second output pole of the battery cell assembly can be assembled together. One end of the first bent part 211 and the third bent part 221 along the second direction is placed on the free end surface of the installation part 121 along the third direction. Then, the second bent part 212 and the first input pole of the distribution box 400, and the fourth bent part 222 and the second input pole of the distribution box 400 are assembled together. Finally, the electrical connection between the distribution box 400 and the battery cell assembly is realized through the lap joint connection of the first bent part 211 and the second bent part 212 along the third direction and the lap joint connection of the third bent part 221 and the fourth bent part 222 along the third direction, making the electrical connection between the distribution box 400 and the battery cell assembly more convenient and reliable.

[0081] In some embodiments of the present invention, such as Figure 8 and Figure 9 shown, the first bent part 211 and the second bent part 212 are stacked at one end of the installation part 121 along the third direction and are connected by a first fastener, and the connection between the first bent part 211 and the second bent part 212 is relatively simple.

[0082] In the prior art, arc discharge is likely to occur at the connection between the first bent part and the second bent part. The discharge of the arc not only easily damages the battery cell assembly and the distribution box, reducing the service life of the battery cell assembly and the distribution box, but may even cause safety accidents such as fire due to the high temperature generated during the arc discharge.

[0083] One end of the first fastener facing away from the installation part 121 is provided with a first insulating cap 213, which can prevent the electrical clearance between the first fastener and other components of the battery pack 1000 from being too small, avoiding arc drawing and causing safety problems.

[0084] In some embodiments of the present invention, such as Figure 8 and Figure 9 shown, the third bent part 221 and the fourth bent part 222 are stacked at one end of the installation part 121 along the third direction and are connected by a second fastener, and the connection between the third bent part 221 and the fourth bent part 222 is relatively simple.

[0085] Arc discharge is likely to occur at the connection between the third bent part and the fourth bent part. The discharge of the arc not only easily damages the battery cell assembly and the distribution box 400, reducing the service life of the battery cell assembly and the distribution box 400, but may even cause safety accidents such as fire due to the high temperature generated during the arc discharge.

[0086] A second insulating cap 223 is provided at one end of the second fastener facing away from the mounting portion 121 to avoid a small electrical gap between the second fastener and other components of the battery pack 1000, thereby avoiding arcing and causing safety problems.

[0087] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, at least one of the first bending part 211 and the second bending part 212 is provided with a first anti-rotation notch 214, and a first anti-rotation column 15 is provided on the mounting portion 121. The first anti-rotation column 15 is clamped in the first anti-rotation notch 214. During the connection process between the first bending part 211 and the second bending part 212, the first bending part 211 and the second bending part 212 can be prevented from rotating after being subjected to force, and the first bending part 211 and the second bending part 212 can be prevented from being displaced, so that the positions of the first bending part 211 and the second bending part 212 are more reliable.

[0088] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, at least one of the third bending member 221 and the fourth bending member 222 is provided with a second anti-rotation notch 224, and the mounting portion 121 is provided with a second anti-rotation column 16, and the second anti-rotation column 16 is clamped in the second anti-rotation notch 224. During the connection process of the third bending member 221 and the fourth bending member 222, the third bending member 221 and the fourth bending member 222 can be prevented from rotating after being subjected to force, and the third bending member 221 and the fourth bending member 222 can be prevented from being displaced, so that the positions of the third bending member 221 and the fourth bending member 222 are more reliable.

[0089] In some embodiments of the utility model, the insulating part is a ceramic part. The ceramic part is resistant to high temperature. After the battery pack 1000 has thermal runaway, the second mounting bracket 5 is not easily melted and deformed, so that the second bending part 212 and the fourth bending part 222 are not easily short-circuited. It has good corrosion resistance and oxidation resistance, and has strong hardness and can resist wear and impact. It also has good insulation performance, light weight, environmental protection and durability, and therefore has high reliability.

[0090] In some embodiments of the present invention, Figure 7 As shown, the adapter structure 100 also includes a first fixing component, which includes a first mounting hole, a first nut, a first plastic part 62 and a first bolt 61 on the second mounting bracket 5. The first plastic part 62 is located between the second mounting bracket 5 and the first nut. The first bolt 61 cooperates with the first nut to fix the second bending part 212 and the fourth bending part 222 on the second mounting bracket 5.

[0091] For example, when producing the second mounting bracket 5, two first mounting holes can be easily constructed on the second mounting bracket 5, and then the two first nuts can be firmly fixed in the two first mounting holes through the first plastic part 62. At this time, the two first bolts 61 are respectively matched with the two first nuts to fix the second bending part 212 and the fourth bending part 222 on the second mounting bracket 5 respectively. The operation is simple and the connection effect is good.

[0092] In some embodiments of the present invention, Figure 6 As shown, the adapter structure 100 also includes a second fixing component, which includes a second mounting hole 71, a second nut, a second plastic part and a second bolt on the second mounting bracket 5. The second plastic part is located between the second mounting bracket 5 and the second nut. The second bolt and the second nut are used in conjunction to install the second mounting bracket 5 on the distribution box 400.

[0093] For example, the second nut can be firmly fixed in the second mounting hole 71 through the second plastic part. At this time, the second bolt is respectively matched with the two second nuts to install the second mounting bracket 5 on the distribution box 400. The operation is simple and the connection effect is good.

[0094] In some embodiments of the present invention, Figure 6 As shown, the second mounting bracket 5 is provided with a positioning column 72, and the distribution box 400 is provided with a positioning hole that matches the positioning column 72. Therefore, the second mounting bracket 5 can be positioned and matched with the positioning hole on the distribution box 400 through the positioning column 72, and then fixedly connected through the second fixing component, which can improve assembly efficiency.

[0095] In some embodiments of the present invention, Figure 8 As shown, the first mounting bracket 1 also includes a mounting seat 10, which is arranged at one end of the mounting portion 121 along the third direction away from the adapter structure 100 and extends along the second direction. The adapter structure 100 also includes an electrical connection component 9, which is installed on the mounting seat 10 and extends along the second direction. The electrical connection component 9 is spaced apart from the adapter component 2 in the third direction, thereby making the adapter component 2 and the electrical connection component 9 spaced apart up and down, making it difficult for the adapter component 2 and the electrical connection component 9 to interfere with each other, and also facilitating the assembly of the adapter component 2 and the electrical connection component 9.

[0096] The electrical connection component 9 is used to electrically connect the front drive module and the voltage divider module of the distribution box 400. It can be understood that when the battery pack 1000 is used in a four-wheel drive vehicle, the distribution box 400 is the rear drive distribution box 400. After the electric energy of the battery cell assembly enters the distribution box 400, after meeting the voltage used by the rear drive, it is transmitted to the front drive module by the voltage divider module, thereby realizing the rationality of the vehicle voltage distribution.

[0097] That is to say, the electrical connection component 9 can be electrically connected between the precursor module and the voltage divider module of the distribution box 400. Since the electrical connection component 9 has the function of electrical connection, the electrical connection component 9 is a live structure. By installing the electrical connection component 9 on the mounting base 10, the position of the electrical connection structure can be better fixed, so that the electrical connection structure is stably electrically connected between the precursor module and the voltage divider module of the distribution box 400. In addition, the mounting base 10 has insulating properties, and the mounting base 10 can also better insulate the electrical connection component 9 to avoid short circuit after the electrical connection component 9 contacts other component structures in the battery box.

[0098] In some embodiments of the present invention, Figure 5 and Figure 8 As shown, the electrical connection component 9 includes a first electrical connection member 91 and a second electrical connection member 92. The mounting base 10 has two mounting grooves 13 spaced apart from each other. The two mounting grooves 13 extend along the second direction. The first electrical connection member 91 and the second electrical connection member 92 are respectively installed in the two mounting grooves 13. The first electrical connection member 91 is electrically connected between the third output pole of the voltage divider module and the third input pole of the precursor module; the second electrical connection member 92 is electrically connected between the fourth input pole of the voltage divider module and the fourth output pole of the precursor module.

[0099] It can be understood that the third output pole is the positive pole of the voltage divider module, the fourth input pole is the negative pole of the voltage divider module, the third input pole is the negative pole of the precursor module, and the fourth output pole is the positive pole of the precursor module. The first electrical connector 91 can connect the positive pole of the voltage divider module and the negative pole of the precursor module, and the second electrical connector 92 can connect the negative pole of the voltage divider module and the positive pole of the precursor module, so as to realize the electrical connection between the voltage divider module and the precursor module, and the connection between the positive pole of the voltage divider module and the negative pole of the precursor module and the connection between the negative pole of the voltage divider module and the positive pole of the precursor module are separated to avoid short circuit between the two when they are electrically connected.

[0100] The first electrical connector 91 and the second electrical connector 92 are installed in the mounting groove 13 on the mounting seat 10. The mounting seat 10 is arranged at one end of the mounting portion 121 along the third direction away from the adapter structure 100, so that the adapter component 2 and the electrical connection component 9 are spaced apart from each other, the adapter component 2 and the electrical connection component 9 are not easy to interfere with each other, and it is also conducive to the assembly of the adapter component 2 and the electrical connection component 9.

[0101] In some embodiments of the present invention, Figure 3 and Figure 5As shown, an insulating column 19 is provided at one end of the mounting base 10 close to the distribution box 400, and the insulating column 19 is arranged between two spaced-apart mounting grooves 13. This can help separate the first electrical connector 91 and the second electrical connector 92, facilitate the installation of the first electrical connector 91 and the second electrical connector 92, and also insulate the first electrical connector 91 and the second electrical connector 92 from each other.

[0102] In some embodiments of the present utility model, as Figure 8 shown, the mounting base 10 includes a first mounting base 101. The first mounting base 101 is arranged on the side of the mounting portion 121 facing the distribution box 400. The first electrical connector 91 includes a fifth bending member and a sixth bending member electrically connected on the surface of the first mounting base 101 facing the distribution box 400. The fifth bending member is electrically connected to the third output terminal of the voltage dividing module, and the sixth bending member is electrically connected to the third input terminal of the precursor module; the second electrical connector 92 includes a seventh bending member and an eighth bending member electrically connected on the surface of the first mounting base 101 facing the distribution box 400. The seventh bending member is electrically connected to the fourth input terminal of the voltage dividing module, and the eighth bending member is electrically connected to the fourth output terminal of the precursor module.

[0103] Specifically, in this embodiment, the first electrical connector 91 includes a fifth bending member and a sixth bending member. The fifth bending member is electrically connected to the positive electrode of the voltage dividing module, and the other end is electrically connected to one end of the sixth bending member. The other end of the sixth bending member is electrically connected to the negative electrode of the precursor module. Similarly, the second electrical connector 92 includes a seventh bending member and an eighth bending member. The seventh bending member is electrically connected to the negative electrode of the voltage dividing module, and the other end is electrically connected to one end of the eighth bending member. The other end of the eighth bending member is electrically connected to the positive electrode of the precursor module. The electrical connection between the fifth bending member and the sixth bending member is spaced apart from the electrical connection between the seventh bending member and the eighth bending member, increasing the reliability of the electrical connection between the voltage dividing module and the precursor module.

[0104] In some embodiments of the present utility model, the fifth bending member and the sixth bending member are connected on the first mounting base 101 by a third fastener, and the connection between the fifth bending member and the sixth bending member is relatively simple.

[0105] In some embodiments of the present utility model, the seventh bending member and the eighth bending member are connected on the first mounting base 101 by a fourth fastener, and the connection between the seventh bending member and the eighth bending member is relatively simple.

[0106] In some embodiments of the present utility model, as Figure 3 and Figure 5As shown, at least one of the fifth bending member and the sixth bending member is provided with a third anti-rotation notch 911, and the first mounting seat 101 is provided with a third anti-rotation column 17, and the third anti-rotation column 17 is clamped in the third anti-rotation notch 911. During the connection process of the fifth bending member and the sixth bending member, the fifth bending member and the sixth bending member can be prevented from rotating after being subjected to force, and the fifth bending member and the sixth bending member can be prevented from being displaced, so that the positions of the fifth bending member and the sixth bending member are more reliable.

[0107] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, at least one of the seventh bending part and the eighth bending part is provided with a fourth anti-rotation notch 921, and the first mounting seat 101 is provided with a fourth anti-rotation column 18, and the fourth anti-rotation column 18 is clamped in the fourth anti-rotation notch 921. During the connection process of the seventh bending part and the eighth bending part, the seventh bending part and the eighth bending part can be prevented from rotating after being subjected to force, and the seventh bending part and the eighth bending part can be prevented from being displaced, so that the positions of the seventh bending part and the eighth bending part are more reliable.

[0108] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, the battery pack 1000 includes an intermediate longitudinal beam 200, which is located on the side of the side beam 300 and the distribution box 400 close to the battery cell assembly and extends along the second direction. The mounting seat 10 includes a second mounting seat 102 located on the side of the mounting portion 121 away from the distribution box 400. The second mounting seat 102 extends along the second direction and is detachably mounted in the intermediate longitudinal beam 200. At least one of the clamping portion 81, the guide portion 82 and the limiting portion 83 is provided on the second mounting seat 102. The second mounting seat 102 can be clamped on the intermediate longitudinal beam 200, and the connection between the first mounting bracket 1 and the intermediate longitudinal beam 200 is relatively simple and reliable.

[0109] In some embodiments of the present invention, the battery pack 1000 includes an intermediate longitudinal beam 200, which is located on the side of the side beam 300 close to the battery cell assembly and extends along the second direction. The intermediate longitudinal beam 200 and the groove 301 are arranged relative to each other along the second direction to facilitate the installation connection between the second mounting seat 102 in the adapter structure 100 in the groove 301 and the intermediate longitudinal beam 200, and the connection between the first mounting bracket 1 and the intermediate longitudinal beam 200 is relatively simple and reliable.

[0110] In some embodiments of the present invention, Figure 2 As shown, a receiving groove 1021 is provided at one end of the middle longitudinal beam 200 along the third direction, a guide portion 82 is provided on the second mounting seat 102 , and a matching hole 802 matching with the guide portion 82 is provided on the side wall of the receiving groove 1021 .

[0111] Reference Figure 2 ,Figure 8 and Figure 9 As shown in a specific example, the second mounting seat 102 is detachably mounted on the middle longitudinal beam 200, and a clamping portion 81, a guiding portion 82 and a limiting portion 83 are provided on the second mounting seat 102. Thus, a clamping hole 801 cooperating with the clamping portion 81, a matching hole 802 cooperating with the guiding portion 82, and a limiting hole 803 cooperating with the limiting portion 83 can be respectively provided on the middle longitudinal beam 200. When the first mounting bracket 1 is installed, the guiding portion 82 can slide along the matching hole 802. After the guiding portion 82 slides to a predetermined position, the buckle can cooperate with the clamping hole 801, and the limiting protrusion can cooperate with the limiting hole 803, so that the first mounting bracket 1 can be better disassembled and assembled.

[0112] Further, the matching hole 802 includes a first matching portion and a second matching portion, the first matching portion extends along the third direction and one end extends to the open mouth of the accommodating groove 1021, one end of the second matching portion is connected to the end of the first matching portion away from the open mouth of the accommodating groove 1021, and the other end extends along the second direction in a direction away from the distribution box 400. When the first mounting bracket 1 is installed, the guide portion 82 can slide along the first matching portion, and after the guide portion 82 slides to the bottom of the first matching portion, the guide portion 82 slides along the second matching portion toward the distribution box 400. After the guide portion 82 reaches the specified position, the buckle can be matched with the snap-on hole 801, and the limiting protrusion can be matched with the limiting hole 803, so that the first mounting bracket 1 can be well disassembled and assembled, and the position of the guide portion 82 is more reliable.

[0113] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the adapter structure 100 further includes a protective member 3, which is detachably mounted on the mounting portion 121. The protective member 3 is an insulating member, and the protective member 3 has a receiving space opening toward the adapter assembly 2. At least part of the adapter assembly 2 is located in the receiving space. The protective member 3 is used to separate the adapter assembly 2 from other components of the battery pack 1000, wherein the protective member 3 is an insulating member.

[0114] That is to say, the protective member 3 can accommodate the adapter assembly 2 in the accommodating space, thereby further insulating the adapter assembly 2, thereby avoiding arc discharge between the charged adapter assembly 2 and other metal structures or charged structures.

[0115] like Figure 8 and Figure 10As shown, the protective member 3 includes a first side panel 32, a second side panel 33 and a connecting plate 34, the first side panel 32 and the second side panel 33 are connected on both sides of the connecting plate 34, the first side panel 32, the second side panel 33 and the connecting plate 34 form a accommodating space opening downward, the protective member 3 can be covered on the adapter assembly 2, specifically, a snap-in groove 321 or a snap-in hole can be provided on the first side panel 32 and the second side panel 33, and a snap-in protrusion 14 can be provided on the mounting portion 121, thereby, the first side panel 32 can be snap-fitted to the left side surface of the mounting portion 121, and the second side panel 33 can be snap-fitted to the right side surface of the mounting portion 121, thereby completing the installation of the protective member 3, and it is also easy to disassemble and replace the protective member 3.

[0116] In some embodiments of the present invention, Figure 1 As shown, the side wall of the protective member 3 is provided with a pressure relief window 31 connected to the accommodation space. That is to say, when the protective member 3 is arranged close to the adapter assembly 2 and at least part of the adapter assembly 2 is located in the accommodation space, when thermal runaway occurs in the battery cell assembly, the high-temperature and high-pressure gas entering the accommodation space is not easy to be discharged from the accommodation space. For example, if the first mounting bracket 1 is made of plastic material, the high-temperature and high-pressure gas is easy to melt the first mounting bracket 1. By providing the pressure relief window 31 on the protective member 3, the high-temperature and high-pressure gas can be better discharged from the accommodation space.

[0117] Optionally, the protective member 3 is an integrally molded mica member, that is, the protective member 3 can be constructed of mica material by integral molding. The mica material has the characteristics of good insulation, high temperature resistance, good structural strength, good chemical stability, etc. Therefore, when the protective member 3 is covered on the first mounting bracket 1, it can better avoid the high temperature caused by short circuit of the adapter assembly 2 or the high temperature after thermal runaway of the battery cell assembly affecting the insulation of the protective member 3, so that the protective member 3 can reliably insulate the adapter assembly 2 from the external structure.

[0118] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the mounting portion 121 includes a first mounting portion 11 and a second mounting portion 12 spaced apart along a first direction, the mounting seat 10 extends along the front-to-back direction, the first mounting portion 11 and the second mounting portion 12 extend along the up-down direction and are spaced apart along the left-right direction.

[0119] The adapter structure 100 further includes a separator 4 , which is disposed between the first mounting portion 11 and the second mounting portion 12 and is used to separate the first adapter component 21 from the second adapter component 22 . The separator 4 is an insulating member.

[0120] The separator 4 is in the shape of a plate and can be installed on the middle longitudinal beam 200 in the battery pack 1000. The separator 4 can better separate the first adapter assembly 21 from the second adapter assembly 22. Therefore, even if the first mounting portion 11, the second mounting portion 12 and the separator 4 are deformed by heat melt, it is not easy for a short circuit to occur between the first adapter assembly 21 and the second adapter assembly 22.

[0121] Optionally, the separator 4 is an integrally molded mica piece. The separator 4 can be constructed of mica material by integral molding. The mica material has good insulation, high temperature resistance, good structural strength, chemical stability and other properties. Therefore, when the separator 4 is arranged between the first mounting portion 11 and the second mounting portion 12, the first adapter component 21 and the second adapter component 22 can be better separated, so that the first adapter component 21 and the second adapter component 22 are not prone to short circuit.

[0122] The electric device according to the embodiment of the present invention includes the battery pack 1000 mentioned above.

[0123] According to the electrical equipment of the embodiment of the utility model, the distribution box 400 is arranged in the accommodating cavity of the side beam 300, the battery cell assembly is arranged on one side of the side beam 300 along the second direction, and a groove 301 is provided on the side of the side beam 300 facing the battery cell assembly, and the groove 301 is arranged opposite to the distribution box 400. At least a part of the adapter structure 100 is arranged in the groove 301. The adapter structure 100 can be arranged in the groove 301 which is easy for the installer to observe. The electrical connection process between the battery cell assembly and the distribution box 400 can be within the field of view of the installer, so that the electrical connection operation between the battery cell assembly and the distribution box 400 is relatively simple.

[0124] Other structures and operations of the battery pack 1000 and the electrical equipment having the same according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
