For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0057] Reference below Figure 1-Figure 8 The following describes a switching structure 100 according to an embodiment of the present utility model. Figure 1 and Figure 2 As shown, it has an up and down direction, a left and right direction, and a front and back direction. In the present application, the first direction can be referred to as the left and right direction, the second direction can be referred to as the front and back direction, and the third direction can be referred to as the up and down direction. This will not be elaborated in the following description of the present application, but the above definition of the present application is only for the convenience of describing the present application, and is not a limitation on the first direction, second direction and third direction of the present application.

[0058] According to the adapter structure 100 of the embodiment of the utility model, the adapter structure 100 is used for a battery pack, which includes a battery box and a battery cell assembly and a distribution box 400 installed in the battery box. The battery cell assembly and the distribution box 400 can be electrically connected through the adapter structure 100, and the battery box may include a box body with an opening and a battery cover plate covering the opening.

[0059] refer to Figure 6 As shown, the adapter structure 100 includes a first mounting bracket 1 and an adapter assembly 2, the adapter assembly 2 is mounted on the first mounting bracket 1, and the adapter assembly 2 is used to electrically connect the battery core assembly and the distribution box 400, wherein the first mounting bracket 1 is an insulating member.

[0060] That is to say, the adapter assembly 2 can be electrically connected between the battery cell assembly and the distribution box 400. Since the adapter assembly 2 has the function of electrical connection, the adapter assembly 2 is a live structure. By installing the adapter assembly 2 on the first mounting bracket 1, the position of the adapter structure 100 can be better fixed, so that the adapter structure 100 can be stably electrically connected between the battery cell assembly and the distribution box 400. In addition, the first mounting bracket 1 with insulating properties can also better insulate the adapter assembly 2 to avoid short circuit after the adapter assembly 2 contacts other component structures in the battery box.

[0061] Furthermore, if Figure 1As shown, the adapter structure 100 further includes a protective member 3, which is disposed on a side of the adapter assembly 2 facing the top wall of the battery pack, and is used to separate the adapter assembly 2 from the top wall of the battery pack, wherein the protective member 3 is an insulating member.

[0062] That is to say, after the adapter assembly 2 is installed on the first mounting bracket 1 and electrically connected between the battery cell assembly and the distribution box 400, arc discharge is likely to occur between the adapter assembly 2 and components such as the top wall of the battery pack. It should be noted that the arc discharge is not only likely to damage the battery cell assembly and the distribution box 400, and reduce 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 by the arc discharge. Therefore, in the present application, a protective member 3 is provided, which can separate the adapter assembly 2 from the top wall of the battery pack, thereby effectively avoiding arc discharge between the charged adapter assembly 2 and the metal wall panel.

[0063] Exemplarily, the top wall of the battery pack can be a battery cover. After the adapter assembly 2 is installed on the first mounting bracket 1, it is close to the battery cover. Therefore, the adapter assembly 2 can be separated from the battery cover by the protective member 3, thereby avoiding arc discharge between the grab assembly and the battery cover.

[0064] Therefore, according to the adapter structure 100 of the embodiment of the utility model, by setting the protective part 3, the arc discharge phenomenon between the charged adapter assembly 2 and the metal wall plate of the battery box can be effectively avoided, the battery cell assembly and the distribution box 400 can be better protected, thereby ensuring the service life of the battery cell assembly and the distribution box 400, and also avoiding safety accidents such as fire caused by the high temperature generated during arc discharge.

[0065] In some embodiments of the present invention, Figure 1 and Figure 8 As shown, the protective member 3 has a receiving space opening toward the adapter assembly 2, and at least a portion of the adapter assembly 2 is located in the receiving space. In other words, the protective member 3 can accommodate the adapter assembly 2 in the receiving 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.

[0066] In some embodiments of the present invention, Figure 1 and Figure 8As 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.

[0067] 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.

[0068] Reference Figure 1-Figure 8 A specific example of the protective member 3 shown is that the first mounting bracket 1 includes a first mounting portion 11 and a second mounting portion 12 both extending in the up-down direction, the first mounting portion 11 and the second mounting portion 12 are spaced apart in the left-right direction, the adapter assembly 2 can be installed on the end surfaces of the first mounting portion 11 and the second mounting portion 12, the protective member 3 includes a first side plate 32, a second side plate 33 and a connecting plate 34, the first side plate 32 and the second side plate 33 are connected on both sides of the connecting plate 34, the first side plate 32, the second side plate 33 and the connecting plate 34 construct 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 plate 32 and the second side plate 33, and a snap-in protrusion 14 can be provided on the first mounting portion 11 and the second mounting portion 12, thereby, the first side plate 32 can be snap-fitted to the left side surface of the first mounting portion 11, and the second side plate 33 can be snap-fitted to the right side surface of the second mounting portion 12, thereby completing the installation of the protective member 3, and it is also easy to disassemble and replace the protective member 3. Figure 3 In the embodiment, the first mounting portion 11 and the second mounting portion 12 are both rectangular columns extending in the up-down direction.

[0069] Furthermore, after the protective member 3 is installed, when the high-temperature and high-pressure gas enters the accommodation space from the front and rear directions, the upper side, left side and right side of the high-temperature and high-pressure gas are blocked by the protective member 3, making it difficult for the high-temperature and high-pressure gas to be discharged. Therefore, a pressure relief window 31 can be constructed on the first side panel 32 and the second side panel 33, so that the high-temperature and high-pressure gas can be better discharged from the pressure relief window 31 to the outside of the accommodation space, so as to avoid the high-temperature and high-pressure gas from damaging the first mounting bracket 1.

[0070] In some embodiments of the utility model, the adapter assembly 2 includes a first adapter assembly 21 and a second adapter assembly 22, the first adapter assembly 21 is electrically connected between the first output pole of the battery cell assembly and the first input pole of the distribution box 400; the second adapter assembly 22 is electrically connected between the second output pole of the battery cell assembly and the second input pole of the distribution box 400, the first mounting bracket 1 includes a first mounting portion 11 and a second mounting portion 12 spaced apart in a first direction, the first adapter assembly 21 is mounted on the first mounting portion 11, and the second adapter assembly 22 is mounted on the second mounting portion 12. Optionally, the protective member 3 is detachably mounted on the first mounting portion 11 and / or the second mounting portion 12.

[0071] Reference Figure 1-Figure 8 A specific example is shown, the first output pole is the positive pole of the battery cell, the second output pole is the negative pole of the battery cell, 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 adapter assembly 21 includes a battery cell positive copper bus 201, a first adapter copper bus (i.e., the first bending piece 211) and a positive copper bus of the distribution box 400 (i.e., the second bending piece 212), one end of the battery cell positive copper bus 201 is electrically connected to the positive pole of the battery cell, and the other end is electrically connected to one end of the first adapter copper bus, the other end of the first adapter copper bus is fixedly connected to one end of the positive copper bus of the distribution box 400 at the upper end of the first mounting portion 11, and the other end of the positive copper bus of the distribution box 400 is electrically connected to the positive pole of the distribution box 400. Similarly, the second adapter assembly 22 includes a negative copper bar 202 of the battery cell, a second adapter copper bar (i.e., the third bending piece 221) and a negative copper bar of the distribution box 400 (i.e., the fourth bending piece 222), one end of the negative copper bar 202 of the battery cell is electrically connected to the negative electrode of the battery cell, and the other end is electrically connected to one end of the second adapter copper bar, the other end of the second adapter copper bar is fixedly connected to one end of the negative copper bar of the distribution box 400 at the upper end of the second mounting portion 12, and the other end of the negative copper bar of the distribution box 400 is electrically connected to the negative electrode of the distribution box 400. Therefore, by setting the first mounting portion 11 and the second mounting portion 12 spaced apart, it is not only easy to separate the first adapter assembly 21 and the second adapter assembly 22 to avoid short circuit between the two when they are electrically connected, but also better avoid the first mounting portion 11 or the second mounting portion 12 causing a short circuit between the first adapter assembly 21 and the second adapter assembly 22 when the battery cell assembly is thermally runaway and melts and deforms.

[0072] In some embodiments of the present invention, Figure 1-Figure 3 As shown, 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, and the separator 4 is an insulating member.

[0073] refer to Figure 1-Figure 3In a specific example shown, the partition 4 is in the shape of a plate and can be installed on the middle longitudinal beam 200 in the battery box. The partition 4 can better separate the first adapter component 21 from the second adapter component 22. Therefore, even if the first mounting portion 11, the second mounting portion 12 and the partition 4 are deformed by heat melting, the first adapter component 21 and the second adapter component 22 are not easily short-circuited.

[0074] 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.
