Description

Technical Field

[0001] The present application relates to the field of insulating bases, and in particular to an insulating base, a battery and a vehicle. Background Art

[0002] Today's electric vehicles are a complex system consisting of multiple key parts, especially the power battery pack, which is one of the core components of electric vehicles. It not only provides power for the vehicle, but also involves energy management, safety and reliability. In the power battery pack, the application of copper busbars is very critical, mainly used to connect the cells inside the battery module and the electrical connection between different modules.

[0003] However, in the process of developing the battery pack structure of electric vehicles, due to the limited internal space of the power battery pack, the two copper busbars are often too close to each other. During driving, the copper busbars shake with the vibration of the whole vehicle, and the shaking will cause wear on the insulation layer on the copper busbar. At this time, since the two copper busbars are too close to each other, their creepage distance is also too close, so there is a risk of high-voltage short circuit. Summary of the invention

[0004] The purpose of the present application is to provide an insulating base, a battery and a vehicle.

[0005] According to a first aspect of an embodiment of the present application, an insulating base is provided, the insulating base comprising:

[0006] At least two mounting parts, the mounting parts are used to mount the electric busbar;

[0007] An isolation portion, the isolation portion is arranged between two adjacent mounting portions, the isolation portion comprises at least two isolation units, an isolation space is arranged between the two isolation units, and the isolation space comprises an opening;

[0008] Wherein, at least a portion of the creepage path between the electric bus bars in the two mounting portions is arranged from the opening into the isolation space.

[0009] Based on the above configuration, the creepage path between the two electric bars will crawl through the inner wall of the isolation space, and the distance of the creepage path becomes longer compared to the previous creepage path that only passes through one side of the isolation part. That is, when the insulating layer on the electric bar is worn, the current between the two electric bars is not easy to pass through the creepage path, thereby reducing the risk of high-voltage short circuit.

[0010] In some embodiments, the isolation portion includes an inner convex unit, the isolation space includes an isolation inner wall, and the inner convex unit is disposed on the isolation inner wall;

[0011] The creepage path enters the isolation space from the opening and is arranged along the isolated inner wall through the inner convex unit.

[0012] Based on the above configuration, since the creepage path needs to pass through the inner wall and the inner convex unit is arranged on the inner wall, the creepage path also needs to cross the inner convex unit arranged on the inner wall, thereby further increasing the length of the creepage path and further reducing the risk of high-voltage short circuit.

[0013] In some embodiments, the inner convex unit includes a first subunit and a second subunit connected to each other, and the first subunit is connected to the isolation inner wall;

[0014] And the length of the second subunit along the length direction of the isolation unit is greater than the length of the first subunit along the length direction of the isolation unit.

[0015] Based on the above configuration, since the length of the second subunit along the length direction of the isolation unit is greater than the length of the first subunit along the length direction of the isolation unit, the creepage path forms a step shape in the inner convex unit, further increasing the length of the creepage path, thereby further reducing the risk of high-voltage short circuit.

[0016] In some embodiments, the number of the inner convex units is multiple, and the multiple inner convex units are arranged on the isolation inner wall at intervals;

[0017] The creepage path is arranged through a plurality of the inner convex units.

[0018] After the above arrangement, since the creepage path needs to pass through multiple inner convex units, the length of the creepage path is increased relative to a single inner convex unit, thereby further reducing the risk of high-voltage short circuit. In addition, the present embodiment arranges multiple inner convex units at intervals, which also avoids the creepage paths F between multiple inner convex units being connected in series.

[0019] In some embodiments, the isolation inner wall includes a first wall surface and a second wall surface that are arranged opposite to each other, and a plurality of the inner convex units are arranged at intervals on the first wall surface and the second wall surface, respectively, and a spacing space is arranged between the plurality of the inner convex units;

[0020] The inwardly convex unit located on the first wall surface is arranged toward the spacing space located on the second wall surface, and the inwardly convex unit located on the second wall surface is arranged toward the spacing space located on the first wall surface.

[0021] With such a configuration, on the one hand, the inner convex units can be arranged in a staggered manner, thereby increasing the physical distance between the inner convex units located on the first wall surface and the second wall surface, preventing the inner convex units from touching each other, thereby reducing the creepage path. On the other hand, under the influence of the vibration of the entire vehicle, the insulating base will inevitably be impacted by the electric row and relatively deformed. Under the above configuration, even if the insulating base is slightly deformed, since the inner convex units are arranged facing the opposite spacing space, they will not directly touch the opposite inner convex unit or wall surface, thereby avoiding the reduction of the creepage path and increasing the stability of the insulating base.

[0022] In some embodiments, the isolation portion includes an outer convex unit, the isolation unit includes an isolation outer wall, the isolation outer wall is arranged toward the electric bus, and the outer convex unit is arranged on the isolation outer wall;

[0023] The creepage path starts from the outer protrusion unit, passes through the isolation outer wall, and then enters the isolation space from the opening.

[0024] After the convex unit is provided, the mounting portion will first contact the convex unit, and thus the creepage path F starts from the convex unit, thereby extending the length of the entire creepage path, thereby further reducing the risk of high-voltage short circuit.

[0025] In some embodiments, the edge corners of the convex unit facing away from the isolation outer wall are arranged in an arc shape.

[0026] Based on the above arrangement, when the busbar shakes with the vibration of the entire vehicle, its contact angle is an arc-shaped edge angle, thereby reducing the wear of the insulating layer on the busbar and thereby increasing the service life of the busbar.

[0027] In some embodiments, a cross section of the convex unit is gradually reduced from the isolation outer wall along a thickness direction of the isolation unit.

[0028] Based on the above arrangement, when the electric bus bar shakes with the vibration of the entire vehicle and hits the convex unit, the above shape of the convex unit can withstand the pressure well, thereby preventing the convex unit from being damaged.

[0029] In some embodiments, the insulating base further includes a fixing groove and a fixing member used in conjunction with each other, the fixing groove is provided on the convex unit, and the fixing member is used to fix the electric bus bar to the mounting portion.

[0030] When the electric busbar is fixed to the mounting portion, the electric busbar is disposed in abutment with the outer convex unit.

[0031] Based on the above arrangement, the fixing part and the fixing groove cooperate to attach the busbar to the convex unit, so that when the vehicle shakes, the collision between the busbar and the convex unit can be reduced, thereby reducing the wear of the insulating layer on the busbar, thereby increasing the service life of the busbar and the insulating base.

[0032] In some embodiments, the insulating base further includes a fixing portion, the fixing portion is disposed between the two isolation units, and the fixing portion is disposed in conflict with the two isolation units.

[0033] Based on the above arrangement, when the electric bus shakes and impacts the corresponding isolation unit, since the fixing part is arranged to conflict with the two isolation units, the fixing part applies an opposite force to the isolation unit, thereby keeping the isolation unit stable, and thus preventing the isolation space between the two isolation units from becoming smaller. In summary, the fixing part can enhance the overall stability of the insulating base.

[0034] According to a second aspect of the embodiments of the present application, a battery is provided, comprising: a power bus and an insulating base as described in the above embodiments.

[0035] According to a third aspect of an embodiment of the present application, a vehicle is provided, comprising a battery as described in the above embodiment.

[0036] The beneficial technical effects brought about by the technical solution provided by the embodiment of the present application are:

[0037] An isolation part is provided between two adjacent mounting parts, and the isolation part includes at least two isolation units, an isolation space is provided between the two isolation units, and the isolation space includes an opening; wherein at least part of the creepage path between the electric bars in the two mounting parts is provided from the opening into the isolation space. The creepage path between the two electric bars will crawl through the inner wall of the isolation space, and the distance of the creepage path becomes longer compared to the previous creepage path that only passes through one side of the isolation part. That is, when the insulating layer on the electric bar is worn, the current between the two electric bars is not easy to pass through the creepage path, thereby reducing the risk of high-voltage short circuit.

[0072] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0074] Today's electric vehicles are a complex system consisting of multiple key parts, especially the power battery pack, which is one of the core components of electric vehicles. It not only provides power for the vehicle, but also involves energy management, safety and reliability. In the power battery pack, the application of copper busbars is very critical, mainly used to connect the cells inside the battery module and the electrical connection between different modules.

[0075] However, in the process of developing the battery pack structure of electric vehicles, due to the limited internal space of the power battery pack, the distance between the two copper bars is often too close. Figure 1As shown, the two mounting parts 100 of the insulating base 10 are arranged too close to each other, and the copper busbar shakes with the vibration of the whole vehicle during driving, and the shaking will cause the insulation layer on the copper busbar to be worn. At this time, since the distance between the two copper busbars is too close, the creepage path F between the two copper busbars only passes through one side of the isolation part 200. Therefore, the creepage path F is too close, and the risk of high-voltage short circuit is prone to occur.

[0076] The present application proposes an insulating base 10, referring to Figure 2-Figure 11 As shown, the insulating base 10 includes at least two mounting parts 100 and an isolating part 200. The mounting part 100 is used to mount the electric bus 20, and the isolating part 200 is arranged between two adjacent mounting parts 100. The isolating part 200 includes at least two isolating units 210, and an isolating space 220 is arranged between the two isolating units 210, and the isolating space 220 includes an opening 221. It should be noted that the above-mentioned electric bus 20 can be a copper bus, or an electrically conductive material of other materials, as long as it is used for electricity, it is within the protection scope of the present application. In addition, the insulating base 10 of the present application is set with insulating materials, such as ceramics, glass, plastics (polymers) and composite materials, etc., as long as it is an insulating material, it is within the protection scope of the present application.

[0077] Among them, reference Figure 2 As shown, at least part of the creepage path F between the electric bus bars 20 in the two mounting parts 100 is arranged from the opening 221 into the isolation space 220. That is, the creepage path F enters the isolation space 220 through one end of the opening 221 and creeps along the inner wall of the isolation space 220 to the other end of the opening 221.

[0078] Based on the above configuration, the creepage path F between the two electric bars 20 will crawl along the inner wall of the isolation space 220. Compared with the previous creepage path F that only passes through one side of the isolation portion 200, the distance of the creepage path F becomes longer. Figure 1 and Figure 2 As shown, the creepage path F increases the depth of the isolation space 220 by two times, thereby greatly increasing the length of the creepage path F. That is, when the insulating layer on the electric bus 20 is worn, the current between the two electric buses 20 is not easy to pass through the longer creepage path F, thereby reducing the risk of high-voltage short circuit.

[0079] Based on the above configuration, it should be noted that this embodiment does not limit the depth of the isolation space 220. As long as the depth is such that the creepage path F designed in this application is greater than the original creepage path, it is within the protection scope of this application. For example, the depth of the isolation space 220 can be 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, or 5 cm.

[0080] In one embodiment, reference Figure 3 As shown, the insulating base 10 further includes a fixing portion 300, which is disposed between the two isolation units 210, and the fixing portion 300 is disposed in abutment with the two isolation units 210. That is, the fixing portion 300 is disposed in the isolation space 220 and one end of the fixing portion 300 is in abutment with the first isolation unit 210, and the other end of the fixing portion 300 is in abutment with the second isolation unit 210.

[0081] Based on the above arrangement, when the electric bus 20 shakes and impacts the corresponding isolation unit 210, since the fixing part 300 is arranged to conflict with the two isolation units 210, the fixing part 300 applies an opposite force to the isolation unit 210, so that the isolation unit 210 remains stable, and the isolation space 220 between the two isolation units 210 does not become smaller. In summary, the fixing part 300 can enhance the overall stability of the insulating base 10.

[0082] It should also be noted that the fixing portion 300 here can be made of the same material as the mounting portion 100 and the isolation portion 200, so that the insulating base 10 can be processed in one piece during processing.

[0083] In one embodiment, reference Figure 4 As shown, the isolation portion 200 includes an inner convex unit 230, and the isolation space 220 includes an isolation inner wall 240, and the inner convex unit 230 is arranged on the isolation inner wall 240. That is, one end of the inner convex unit 230 is connected to the isolation inner wall 240, and the other end is extended to the isolation space 220. The creepage path F enters the isolation space 220 from the opening 221, and is arranged along the isolated inner wall 240 through the inner convex unit 230. It should be noted that the specific shape of the inner convex unit 230 here is not limited, and its shape can be trapezoidal, triangular, circular, etc. As long as the creepage path F becomes longer after passing through the inner convex unit 230, it is within the protection scope of the present application.

[0084] Based on the above configuration, since the creepage path F needs to pass through the inner wall 240, and the inner convex unit 230 is disposed on the inner wall 240, the creepage path F also needs to cross the inner convex unit 230 disposed on the inner wall 240. This further increases the length of the creepage path F, thereby further reducing the risk of high-voltage short circuit.

[0085] In one embodiment, reference Figure 4 , Figure 5 as well as Figure 6As shown, the inner convex unit 230 includes a first subunit 231 and a second subunit 232 connected to each other, and the first subunit 231 is connected to the isolation inner wall 240. The length of the second subunit 232 along the length direction Y of the isolation unit 210 is greater than the length of the first subunit 231 along the length direction Y of the isolation unit 210. That is, the width of the second subunit 232 is greater than the width of the first subunit 231, and the first subunit 231 and the second subunit 232 form a T shape.

[0086] Based on the above configuration, since the length of the second subunit 232 along the length direction Y of the isolation unit 210 is greater than the length of the first subunit 231 along the length direction Y of the isolation unit 210, the creepage path F forms a step shape in the inner convex unit 230, further increasing the length of the creepage path F, thereby further reducing the risk of high-voltage short circuit.

[0087] In one embodiment, continue to refer to Figure 4 , Figure 5 as well as Figure 6 The number of the inner convex units 230 is multiple, and the multiple inner convex units 230 are arranged at intervals on the isolation inner wall 240. The creepage path F passes through the multiple inner convex units 230. That is, a row of inner convex units 230 is arranged on the isolation inner wall 240, and the creepage path F needs to pass through the row of inner convex units 230.

[0088] After the above arrangement, since the creepage path F needs to pass through multiple inner convex units 230, the length of the creepage path F is increased relative to a single inner convex unit 230, thereby further reducing the risk of high-voltage short circuit. In addition, the present embodiment arranges multiple inner convex units 230 at intervals, which also avoids the creepage paths F between multiple inner convex units 230 being connected in series.

[0089] In one embodiment, reference Figure 4 , Figure 5 as well as Figure 6 As shown, the isolation inner wall 240 includes a first wall surface 241 and a second wall surface 242 that are oppositely disposed, a plurality of inward convex units 230 are spaced apart from each other on the first wall surface 241 and the second wall surface 242 , and a spacing space 222 is disposed between the plurality of inward convex units 230 .

[0090] The inward convex unit 230 on the first wall surface 241 is arranged toward the spacing space 222 on the second wall surface 242, and the inward convex unit 230 on the second wall surface 242 is arranged toward the spacing space 222 on the first wall surface 241. That is, the inward convex unit 230 is arranged facing the opposite spacing space 222. Of course, in other embodiments, the inward convex units 230 on the first wall surface 241 and the second wall surface 242 may also be arranged opposite to each other.

[0091] With such a configuration, on the one hand, the inner convex units 230 can be arranged in a staggered manner, thereby increasing the physical distance between the inner convex units 230 located on the first wall surface 241 and the second wall surface 242, preventing the inner convex units 230 from touching each other, thereby reducing the creepage path F. On the other hand, under the influence of the vibration of the entire vehicle, the insulating base 10 will inevitably be impacted by the electric bus 20 and relatively deformed. Under the above configuration, even if the insulating base 10 is slightly deformed, since the inner convex unit 230 is arranged facing the opposite spacing space 222, it will not directly touch the opposite inner convex unit 230 or wall surface, thereby avoiding the reduction of the creepage path F, thereby increasing the stability of the insulating base 10.

[0092] In one embodiment, reference Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, the isolation part 200 includes a protruding unit 250, and the isolation unit 210 includes an isolation outer wall 260. The isolation outer wall 260 is arranged toward the electric bus 20, and the protruding unit 250 is arranged on the isolation outer wall 260. The creepage path F starts from the protruding unit 250, passes through the isolation outer wall 260, and then enters the isolation space 220 from the opening 221.

[0093] refer to Figure 3 As shown, after the convex unit 250 is provided, the mounting portion 100 will first contact the convex unit 250, so that the creepage path F starts from the convex unit 250, thereby extending the length of the entire creepage path F, thereby further reducing the risk of high-voltage short circuit.

[0094] In one embodiment, reference Figure 7-Figure 11 As shown, the edge corner 251 of the convex unit 250 facing away from the isolation outer wall 260 is arranged in an arc shape. That is, the surface of the convex unit 250 close to the electric bus 20 is arranged in an arc shape.

[0095] Based on the above configuration, when the power bar 20 shakes with the vibration of the vehicle, its contact angle is an arc-shaped edge angle 251, thereby reducing the wear of the insulating layer on the power bar 20 and thereby increasing the service life of the power bar 20.

[0096] In one embodiment, continue to refer to Figure 7-Figure 11 As shown, the cross section of the convex unit 250 is gradually reduced from the isolation outer wall 260 along the thickness direction of the isolation unit 210. In other words, the cross section near the isolation unit 210 is larger and the cross section far from the isolation unit 210 is smaller, that is, the base is larger and the outer part is smaller.

[0097] Based on the above arrangement, when the power bar 20 shakes with the vibration of the entire vehicle and hits the convex unit 250, the above shape of the convex unit 250 can withstand the pressure well, thereby preventing the convex unit 250 from being damaged.

[0098] In one embodiment, the insulating base 10 further includes a fixing groove (not shown in the figure) and a fixing member (not shown in the figure) used in conjunction, the fixing groove is provided in the convex unit 250, the fixing member is used to fix the electric bus 20 to the mounting portion 100, and when the electric bus 20 is fixed to the mounting portion 100, the electric bus 20 is arranged to conflict with the convex unit 250. That is, the fixing member attaches the electric bus 20 to the convex unit 250. It should be noted that the fixing groove here can be a hole provided in the convex unit 250, and the fixing member can be a fixing rope, and the electric bus 20 is attached to the convex unit 250 by passing the rope through the hole. Of course, the fixing groove and the fixing member here can also be other fixing members, as long as the electric bus 20 can be attached to the convex unit 250, they are within the protection scope of the present application.

[0099] Based on the above arrangement, the fixing parts and the fixing grooves cooperate to attach the power bus 20 to the convex unit 250, so that when the vehicle shakes, the collision between the power bus 20 and the convex unit 250 can be reduced, thereby reducing the wear of the insulating layer on the power bus 20, thereby increasing the service life of the power bus 20 and the insulating base 10.

[0100] The present application also provides a battery, which includes a power bank 20 and the insulating base 10 as described in the above embodiment. Since the battery has the insulating base 10, the advantages and functions of the insulating base 10 are also possessed by the battery.

[0101] The present application also provides a vehicle including the above-mentioned battery. The vehicle may be an electric car, an electric truck, etc.

[0102] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
