[0045] As attached Figure 1 As shown, the output pole base of the battery module proposed by the utility model includes a main body 10, a first functional side 101 of the main body 10 is provided with a first connecting mechanism, the output pole is installed on the main body 10 through the first connecting mechanism, and the second functional side 102 of the main body 10 is installed on the end plate 20 through the positioning mechanism and the second connecting mechanism. The positioning mechanism is used to quickly position the main body 10 and the end plate 20 to improve the installation efficiency, eliminate the process of repeatedly adjusting the position of the main body 10 relative to the end plate 20, and save installation time. The second connecting mechanism is used to fix the main body 10 to the end plate 20 and make the main body 10 and the end plate 20 detachably connected.

[0046] The output pole is installed on the end plate 20 through the main body 10, and the first connecting mechanism can realize the connection and fixation of the output pole to ensure the connection quality of the output pole; the main body 10 can provide insulation protection for the output pole, avoid the problems of leakage and short circuit, and improve the safety of use; the setting of the positioning mechanism can enable the main body 10 and the end plate 20 to be quickly installed in place, and the positioning mechanism can cooperate with the second connecting mechanism to realize the rapid installation of the main body 10; the second connecting mechanism is used to realize the fixation of the main body 10 and the end plate 20, and through the setting of the second connecting mechanism, the main body 10 is detachable relative to the end plate 20, which is convenient for disassembly and assembly, with a simple structure and low operation difficulty.

[0047] As attached Figure 1 As shown, the first functional side 101 and the second functional side 102 are distributed on both sides of the main body 10 along the thickness direction of the main body 10, and the first functional side 101 and the second functional side 102 are opposite to each other. The thickness direction of the main body 10 is also the connection direction between the main body 10 and the end plate 20. When the main body 10 is connected to the end plate 20, the main body 10 can be assembled along its own thickness direction toward the side close to the end plate 20. When the main body 10 is removed from the end plate 20, the main body 10 can be disassembled along its own thickness direction toward the side away from the end plate 20.

[0048] In one embodiment of the present invention, Figure 2 and attached Figure 3The positioning mechanism includes a guide member 11 and a positioning groove 21 that cooperates with the guide member 11. The guide member 11 is located on the second functional side 102 of the main body 10. The positioning groove 21 is provided on the mounting surface 201 of the end plate 20. When the main body 10 is connected to the end plate 20, the outer wall of the guide member 11 contacts the inner groove wall of the positioning groove 21. During the installation process, the guide member 11 is slidably matched with the inner groove wall of the positioning groove 21 until the main body 10 is installed in place. Through the cooperation between the guide member 11 and the positioning groove 21, the assembly of the main body 10 and the end plate 20 can be fast and stable, avoiding the problems of skewness and jitter during the connection process, saving the time for adjusting the installation position of the main body 10, and improving the efficiency of the installation.

[0049] In one embodiment of the present invention, as shown in the attached Figure 2 As shown, an opening 211 is provided on a groove wall of the positioning groove 21. The opening 211 penetrates the groove wall at one end close to the main body 10 and penetrates the groove wall along the thickness direction of the end plate 20. The opening 211 is connected to the positioning groove 21. The opening 211 is arranged so that the groove wall includes two stoppers 22 separated by the opening 211. Figure 3 A limiting groove 111 cooperating with the limiting member 22 is provided on the guide member 11. During the connection process between the main body 10 and the end plate 20, the guide member 11 slides with the inner groove wall of the positioning groove 21 until the limiting member 22 is completely accommodated in the limiting groove 111. The installation of the main body 10 and the end plate 20 is completed. The limiting member 22 cooperates with the guide member 11, which can enable the main body 10 and the end plate 20 to be quickly positioned, which is beneficial to improving the installation efficiency.

[0050] In one example, the opening 211 is located in the middle of the slot wall.

[0051] In one example, the limiting member 22 and the limiting groove 111 have the same height dimension along the connection direction between the main body 10 and the end plate 20 .

[0052] In one example, as shown in the attached Figure 2 As shown, the limiting groove 111 is provided on the outer wall of the guide member 11. When the main body 10 is mounted on the end plate 20, the end surface of the main body 10 is flush with the end surface of the limiting member 22. Figure 1 , it is convenient to bundle the steel belt 30 onto the main body 10 and the end plate 20 to improve the connection quality of the battery cell and prevent the battery cell from loosening or position shifting.

[0053] In one embodiment of the present invention, Figure 2 and attached Figure 3The second connecting mechanism includes a fixing column 12 and a card hole 23 that cooperates with the fixing column 12. The fixing column 12 is located on the second functional side 102 of the main body 10. One end of the fixing column 12 is connected to the main body 10, and the other end is a free end. The card hole 23 is opened on the mounting surface 201 of the end plate 20. The fixing column 12 is used to connect with the card hole 23. When the main body 10 is connected to the end plate 20, the fixing column 12 is accommodated in the card hole 23.

[0054] In one example, the fixing column 12 and the locking hole 23 are interference-fitted so that the fixing column 12 and the locking hole 23 are engaged with each other, thereby allowing the main body 10 to be detachably mounted on the end plate 20 .

[0055] In one example, the extending direction of the fixing column 12 is parallel to the connecting direction of the main body 10 and the end plate 20 .

[0056] In one example, the fixing column 12 is configured as a cylindrical member, and of course, it can also be configured as a prismatic member, and those skilled in the art can select one according to actual needs.

[0057] In one example, a first clamp 121 and a second clamp 122 are provided at one end of the fixing column 12 away from the main body 10. The first clamp 121 and the second clamp 122 can be moved closer to each other under the action of an external force to reduce the interval therebetween. The interval between the first clamp 121 and the second clamp 122 can be adjusted so that the first clamp 121 and the second clamp 122 are interference fit in the clamp hole 23, thereby achieving a fixed connection between the main body 10 and the end plate 20.

[0058] Optionally, the outer walls of the first clamp 121 and the second clamp 122 protrude from the outer wall of the fixing column 12. When the fixing column 12 is not connected to the clamp hole 23, that is, the interval between the two is not changed under the action of external force, the distance between the ends of the first clamp 121 and the second clamp 122 that are away from each other is greater than the aperture size of the clamp hole 23. When the fixing column 12 is connected to the clamp hole 23, the interval between the first clamp 121 and the second clamp 122 is reduced, so that the first clamp 121 and the second clamp 122 are interference-fitted into the clamp hole 23, and the main body 10 and the end plate 20 are clamped.

[0059] Optionally, to facilitate disassembly and assembly, when installing the main body 10, the first clamp 121 and the second clamp 122 pass through the clamp hole 23, and the interval between them is restored. At this time, the fixing column 12 is installed in the clamp hole 23, and the first clamp 121 and the second clamp 122 are located on the side of the clamp hole 23 away from the main body 10, which can limit the fixing column 12 and prevent the fixing column 12 from falling out of the clamp hole 23.

[0060] Optionally, the first clamping member 121 and the second clamping member 122 are integrally formed with the fixing column 12 .

[0061] Optionally, the first clamping member 121 and the second clamping member 122 are symmetrically arranged and are both arranged as arc-shaped members. When the fixing column 12 is not connected to the clamping hole 23, the outer contours of the first clamping member 121 and the second clamping member 122 are cocircular.

[0062] In one embodiment of the present invention, as shown in the attached Figure 3 As shown, a receiving groove 112 is provided at one end of the guide member 11 away from the main body 10, the fixing column 12 is received in the receiving groove 112, and one end thereof is connected to the groove wall of the receiving groove 112 away from the end plate 20, the clamping hole 23 is provided in the positioning groove 21, and is provided on the groove wall of the positioning groove 21 away from the main body 10. Such an arrangement can reduce the overall weight of the main body 10, is beneficial to the lightweight design of the main body 10, and can save costs.

[0063] In one example, two fixing columns 12 are provided in the receiving groove 112, and the two fixing columns 12 are distributed at intervals. Optionally, the two fixing columns 12 are distributed at intervals in the receiving groove 112 along the length direction of the main body 10. One guide member 11 corresponds to the two fixing columns 12, which can improve the installation quality of the main body 10, improve the stability, and effectively avoid the problem of shaking or falling off of the main body 10.

[0064] It can be understood that, since the output pole includes a positive output pole and a negative output pole, the number of the guide members 11 is set to two, and they are distributed at intervals on the second functional side 102 of the main body 10 along the length direction of the main body 10 .

[0065] In one embodiment of the present invention, the first connecting mechanism includes a connecting member 13, Figure 2 and attached Figure 4 The fixing column 12 includes a functional hole 123, which penetrates the fixing column 12 along the thickness direction of the main body 10. The connecting member 13 is arranged on the first functional side 101 of the functional hole 123 and is installed in the functional hole 123. One end of the connecting member 13 close to the first functional side 101 is exposed from the functional hole 123. The connecting member 13 is used to realize the connection between the main body 10 and the positive and negative output poles.

[0066] In one example, the connection member 13 is a copper nut.

[0067] When the battery module is in use, since the battery cells will generate heat during the circulation process, a cooling plate is usually configured on one side of the battery module. The cooling plate is usually a liquid cooling plate. The cooling plate can heat or cool the battery module. To improve the heating or cooling efficiency, the cooling plate needs to cover as much of the surface of the battery module as possible. Therefore, the distance between the steel strip and the output pole needs to be designed to be as small as possible. The output pole base in the prior art is difficult to ensure the creepage distance between the output pole, resulting in poor insulation performance and increased risk of electric shock for operators.

[0068] In one example, in conjunction with Figure 2 and attached Figure 4 The first connecting mechanism also includes a boss 14, which is located on the first functional side 101 of the main body 10. The boss 14 is protruding on the main body 10 and extends along the thickness direction of the main body 10 toward an end away from the second functional side 102. The boss 14 corresponds to the position of the functional hole 123, and the functional hole 123 passes through the boss 14. The connecting member 13 is exposed in the functional hole 123 and contacts with the boss 14. Through the setting of the boss 14, the creepage distance between the output pole and the steel strip 30 can be transferred from the output pole to the boss 14, thereby increasing the creepage distance and reducing the risk of voltage breakdown.

[0069] The installation principle of the output pole base of the battery module proposed by the utility model is as follows:

[0070] When installing the main body 10 on the end plate 20, the operator only needs to press the main body 10 along the connection direction toward the side close to the end plate 20, and the first clamp 121 and the second clamp 122 will contact and be subjected to force with the clamp hole 23, and the interval between the two will be reduced until the first clamp 121 and the second clamp 122 penetrate into the clamp hole 23 and pass out of the clamp hole 23. At this time, the interval between the first clamp 121 and the second clamp 122 is restored, and the first clamp 121 and the second clamp 122 can play a limiting role. The fixing column 12 is clamped in the clamp hole 23 and will not fall out of the clamp hole 23, and the installation of the main body 10 and the end plate 20 is completed.

[0071] The disassembly principle of the output pole base of the battery module proposed by the utility model is as follows:

[0072] When the main body 10 needs to be removed, it is only necessary to apply external force to the first clamp 121 and the second clamp 122 from the side of the clamp hole 23 away from the main body 10 to reduce the distance between them, and then lift them along the connection direction of the main body 10 toward the side away from the end plate 20, so that the first clamp 121 and the second clamp 122 can be disengaged from the clamp hole 23, and the fixing column 12 can be disengaged from the clamp hole 23 without restriction, and the disassembly of the main body 10 can be completed. The operation is simple and convenient.

[0073] In one example, the main body 10, the guide member 11 and the fixing column 12 are integrally formed and are injection molded parts made of ABS (Acrylonitrile butadiene Styrene copolymers), which has good insulation and flame retardant protection and is easy to mass produce.

[0074] Based on the above-mentioned output pole base, the utility model also proposes a protective component of a battery module, including the above-mentioned output pole base, and also including a cover body 40 installed on the main body 10 of the output pole base, the cover body 40 is detachably connected to the main body 10, and the cover body 40 can play a shielding and protective role for the output pole installed on the main body 10 to prevent the output pole from being exposed to the outside, and the cover body 40 includes a cavity, and when the cover body 40 is installed on the first functional side 101 of the main body 10, the output pole is accommodated in the cavity.

[0075] In one embodiment of the present invention, as shown in the attached Figure 6 As shown, the cover body 40 includes a cover plate 41 and a surrounding plate connected to the cover plate 41, the surrounding plate is located on the side of the cover plate 41 close to the main body 10, the surrounding plate includes two mounting plates 42 that are opposite and spaced apart along the length direction of the main body 10, and a side plate 43 connecting the two mounting plates 42, the side plate 43 is connected to one end of the two mounting plates 42, and the cover plate 41 and the surrounding plate cooperate to form a cavity.

[0076] The two mounting plates 42 are configured such that when an external force along the length direction of the main body 10 is applied to the mounting plates 42 , the two mounting plates 42 can have an offset in the length direction of the main body 10 with the connection between the two mounting plates 42 and the cover plate 41 as a reference axis.

[0077] As attached Figure 6 As shown, the dimension of the side plate 43 along the thickness direction of the main body 10 is smaller than the dimension of the mounting plate 42 along the thickness direction of the main body 10, so that the side plate 43 forms an avoidance area 44 on the side close to the main body 10, and the avoidance area 44 is connected to the cavity, and is used to avoid the output pole, as well as its connection with the external structure or load, etc., which can provide good insulation protection for the output pole.

[0078] In one example, the cover plate 41, the mounting plate 42 and the side plate 43 are integrated into one piece by injection molding, which has a simple structure and is convenient for mass production.

[0079] In one example, the cover 40 is made of ABS (Acrylonitrile butadiene Styrene copolymers), which has good insulation and flame retardant properties, eliminating the safety hazards of leakage and electric shock to operators.

[0080] In one embodiment of the present invention, as shown in the attached Figure 5As shown, the first functional side 101 of the main body 10 is provided with two guide plates 15 cooperating with the two mounting plates 42 and a baffle plate 16 cooperating with the side plate 43. The two guide plates 42 are arranged opposite to each other and spaced apart along the length direction of the main body 10. When the cover body 40 is installed on the main body 10, the end of the mounting plate 42 away from the cavity contacts and slides with the guide plate 15, and the side plate 43 and the baffle plate 16 are arranged opposite to each other and spaced apart along the width direction of the main body 10.

[0081] In one example, the guide plate 15 , the baffle plate 16 and the main body 10 are integrally formed by injection molding.

[0082] In one embodiment of the present invention, as shown in the attached Figure 5 As shown, the cover body 40 is detachably mounted on the main body 10 by means of a first mounting mechanism 50 and a second mounting mechanism 60, the second mounting mechanism 60 includes a connecting portion located on the inner wall of the cavity, the first mounting mechanism 50 is located on the outer surface of the cover body 40 opposite to the inner wall, and the first mounting mechanism 50 and the second mounting mechanism 60 are located on the same side of the output pole along the length direction of the main body 10.

[0083] More specifically, the first mounting mechanism 50 and the second mounting mechanism 60 are located on the same mounting plate 42, the first mounting mechanism 50 is located on the side of the mounting plate 42 away from the cavity, and the second mounting mechanism 60 is located on the side of the mounting plate 42 close to the cavity. The first mounting mechanism 50 and the second mounting mechanism 60 cooperate to ensure a stable and secure connection between the cover body 40 and the main body 10.

[0084] It can be understood that one cover body 40 includes two mounting plates 42 , and therefore, at least two first mounting mechanisms 50 are provided, and at least two second mounting mechanisms 60 are provided.

[0085] It can be understood that two covers 40 are detachably mounted on the main body 10 .

[0086] In one embodiment of the present invention, Figure 5 and attached Figure 6 The first mounting mechanism 50 includes a clamping member 51 protruding from the mounting plate 42. The clamping member 51 is protruding from the side of the mounting plate 42 away from the cavity. A clamping groove 151 cooperating with the clamping member 51 is opened on the main body 10. When the cover body 40 is connected to the main body 10, the clamping member 51 is clamped in the clamping groove 151. The cover body 40 and the main body 10 are fixed by clamping. The structure is simple, the fixing effect is good, and it is convenient to disassemble.

[0087] In one example, the clamping member 51 and the mounting plate 42 are integrally formed.

[0088] In one example, as shown in the attached Figure 5 As shown, the slot 151 is formed on the guide plate 15 .

[0089] In one example, as shown in the attached Figure 5 As shown, a guide slope 52 is provided at one end of the clip 51 away from the cavity. The guide slope 52 gradually reduces the size of the clip 51 along the length direction of the main body 10 toward the side close to the main body 10. When the cover body 40 is installed on the main body 10, the guide slope 52 makes it easy for the clip 51 to enter the slot 151. When the cover body 40 is removed from the main body 10, the guide slope 52 makes it easy for the clip 51 to escape from the slot 151, so as to facilitate disassembly and assembly.

[0090] In one embodiment of the present invention, Figure 5 and attached Figure 6 The second mounting mechanism 60 includes a support sheet 61, which is protruding from one end of the mounting plate 42 close to the main body 10. The connecting portion includes a stopper 62, which is protruding from one end of the support sheet 61 close to the cavity, and the stopper 62 protrudes and extends along the length direction of the main body 10. A limiting groove 17 is provided on the first functional side 101 of the main body 10, and the limiting groove 17 cooperates with the support sheet 61 and the stopper 62 to achieve snap connection.

[0091] In one example, the support sheet 61 and the stopper 62 are integrally formed.

[0092] In one example, the number of the supporting pieces 61 on one mounting plate 42 is set to two, and the supporting pieces 61 are spaced apart on the mounting plate 42 along the width direction of the main body 10 .

[0093] In one example, as shown in the attached Figure 7 As shown, the limiting groove 17 includes a first groove 171 and a second groove 172, the first groove 171 and the second groove 172 are connected, and penetrate the main body 10 along the thickness direction of the main body 10, the first groove 171 is used to cooperate with the support sheet 61, and the size of the support sheet 61 in the thickness direction of the main body 10 is greater than the groove depth size of the first groove 171 in the thickness direction of the main body 10, the size of the first groove 171 in the length direction of the main body 10 is greater than the size of the support sheet 61 in the length direction of the main body 10, and the second groove 172 cooperates with the stopper 62. When the cover body 40 is installed on the main body 10, the support sheet 61 is penetrated in the first groove 171 and passes through the first groove 171, and the stopper 62 passes through the second groove 172, wherein the orthographic projection of the stopper 62 along the thickness direction of the main body 10 partially overlaps with the orthographic projection of the second groove 172 along the thickness direction of the main body 10.

[0094] The cooperation between the first slot 171 and the support sheet 61 can guide the installation of the cover body 40, stabilize the installation process, and reduce the skewing or shaking of the cover body 40. The stopper 62 cooperates with the second slot 172 to play a good positioning role in the installation process of the support sheet 61 and the first slot 171, so that the support sheet 61 can be installed in place at one time, saving the time for adjusting the installation position and improving the installation efficiency.

[0095] In one example, as shown in the attached Figure 6 As shown, a slope 611 is provided at one end of the support sheet 61 away from the cavity. The slope 611 gradually reduces the size of the support sheet 61 along the length direction of the main body 10 toward the side close to the main body 10, so as to facilitate the installation of the support sheet 61 into the first slot 171 or remove it from the first slot 171, which is beneficial to improve the disassembly and assembly efficiency.

[0096] When it is necessary to remove the cover body 40 from the main body 10, the operator only needs to apply external force to the mounting plate 42 along the length direction of the main body 10 to reduce the size of the cavity in the length direction of the main body 10, and the support sheet 61 is offset in the first slot 171 along the length direction of the main body 10 along with the mounting plate 42, and the clip 51 partially disengages from the slot 151. The orthographic projection of the stopper 62 along the thickness direction of the main body 10 coincides with the orthographic projection of the second slot 172 along the thickness direction of the main body 10. At this time, the operator lifts the cover body 40 to the side away from the main body 10, and the stopper 62 can pass through the second slot 172 until the clip 51 is completely disengaged from the slot 151. The fixed relationship between the cover body 40 and the main body 10 can be released, and the cover body 40 can be removed. The disassembly and assembly are convenient, and the structure is simple.

[0097] In one embodiment of the present invention, the cover body 40 is provided with a guide mechanism, as shown in the attached Figure 6 As shown, the guide mechanism includes a guide post 45, which is protruding from one end of the mounting plate 42 away from the cavity. Figure 7 A guide groove 18 cooperating with the guide column 45 is provided on the main body 10. When the cover body 40 is installed on the main body 10, the guide column 45 is slidably arranged in the guide groove 18. The guide column 45 cooperates with the guide groove 18 to play a good guiding role in the installation of the cover body 40, so that the cover body 40 can be stably and efficiently installed on the main body 10 until the first installation mechanism 50 and the second installation mechanism 60 are installed in place, which saves the time of fine-tuning the position of the cover body 40 and improves the installation efficiency.

[0098] In one example, the guide post 45 and the mounting plate 42 are integrally formed.

[0099] In one example, the orthographic projection of the guide post 45 along the thickness direction of the main body 10 is semicircular, and the orthographic projection of the guide groove 18 along the thickness direction of the main body 10 is semicircular.

[0100] In one example, the number of guide pillars 45 on a mounting plate 42 is set to two, the two guide pillars 45 are distributed on the mounting plate 42 along the width direction of the main body 10, the clip 51 is protruded between the two guide pillars 45, and the dimension of the clip 51 along the length direction of the main body 10 is larger than the dimension of the guide pillar 45 along the length direction of the main body 10.

[0101] In summary, the output pole base of the battery module proposed in the utility model is adopted, and the output pole is installed on the end plate 20 through the main body 10. The first connecting mechanism can realize the connection and fixation of the output pole to ensure the connection quality of the output pole; the main body 10 can provide insulation protection for the output pole, avoid the problems of leakage and short circuit, and improve the safety of use; the setting of the positioning mechanism can enable the main body 10 and the end plate 20 to be quickly installed in place, and the positioning mechanism can cooperate with the second connecting mechanism to realize the rapid installation of the main body 10; the second connecting mechanism is used to realize the fixation of the main body 10 and the end plate 20, and through the setting of the second connecting mechanism, the main body 10 is detachable relative to the end plate 20, which is convenient for disassembly and assembly, with a simple structure and low operation difficulty.

[0102] In summary, the protective component of the battery module proposed by the utility model is adopted, by setting a cover body 40 on the first functional side 101 of the main body 10, and the cover body 40 covers the outer side of the output pole, which can protect and insulate the output pole so that the output pole is not exposed to the outside, reducing the risk of electric shock for operators, improving the safety of the battery module, and having a simple structure and convenient disassembly and assembly; the first mounting mechanism 50 and the second mounting mechanism 60 cooperate to enable the cover body 40 to be firmly installed on the main body 10, which can effectively avoid the problem of the cover body 40 falling off during transportation, and the structure is reliable.
