Abstract
Description
Technical Field
[0001] The present application relates to the field of batteries, and in particular to a wiring harness isolation plate assembly, a battery and an electrical device. Background Art
[0002] A battery may generally include one or more battery modules, each of which may include one or more battery cells, and multiple battery cells may be connected in series, in parallel, or in a series-parallel hybrid manner. In some cases, in a battery having multiple battery modules, multiple battery modules need to be connected. After combining multiple battery modules, impurities entering between the battery modules may easily cause insulation failure of the battery. Utility Model Content
[0003] The present application provides a wiring harness isolation plate assembly, a battery and an electrical device, aiming to improve the problem of battery insulation failure caused by impurities entering between battery modules.
[0004] In order to achieve the above technical effects, a technical solution adopted by the present application is to provide a wiring harness isolation plate assembly, including:
[0005] Two plates, the two plates are arranged at an interval;
[0006] The fixing belt is detachably connected to at least one plate body, and covers the gap between the two plate bodies.
[0007] The wiring harness isolation plate assembly provided in the example of the present application can be installed on the battery module, and the gap between the battery modules is blocked by the fixing belt to prevent the welding slag generated during the welding and other processing of the battery modules from entering the gap between the battery modules, so as to reduce the problem of battery insulation failure caused by impurities entering the gap between the battery modules.
[0008] The fixing belt and the plate body connected to the fixing belt are integrally arranged, a first slot is provided at the connection between the plate body and the fixing belt, the number of the first slots is multiple, the connection line of the multiple first slots forms a breaking line, the fixing belt has a first end and a second end arranged along the length direction, and the breaking line extends from the first end of the fixing belt to the second end. In this example, by integrally arranging the fixing belt with the corresponding plate body, it is convenient to form the fixing belt and the corresponding plate body as one piece, and to facilitate the processing of both. Since the first slot is used to form the breaking line in this example, the position of the first slot can form a weak area at the connection between the fixing belt and the corresponding plate body, and the fixing belt can be torn off along the extension direction of the breaking line to facilitate the removal of the fixing belt.
[0009] The first slot is a through slot that runs through the thickness direction of the fixing belt, or the first slot is a sunken slot set along the thickness direction of the fixing belt. In this example, by using a through slot or a sunken slot, the first slot can form a weak area at the connection between the fixing belt and the corresponding plate, making it convenient to disconnect the connection between the fixing belt and the corresponding plate.
[0010] The width of the first slot is not less than 0.1 mm and not more than 1 mm. In this example, by limiting the width of the first slot, it is easy to remove the fixing belt, and the fixing belt can be used to prevent impurities from entering the shielding structure between adjacent battery modules.
[0011] The distance between adjacent first slots is not less than 0.5 mm and not more than 1.5 mm. In this example, by limiting the distance between adjacent first slots, on the one hand, the fixing belt can be more easily removed, and on the other hand, before the fixing belt is removed, the fixing belt is not easily deformed relative to the corresponding plate, so that the fixing belt can be blocked in the gap between adjacent display modules.
[0012] The fixing belt and the plate body connected to the fixing belt are integrally arranged, and a first slot is provided at the connection between the plate body and the fixing belt, and the first slot is a sunken slot arranged along the thickness direction of the fixing belt; the fixing belt has a first end and a second end arranged along the length direction, and the first slot extends from the first end to the second end of the fixing belt. In this example, by setting the first slot as a sunken slot arranged along the length direction of the fixing belt, on the one hand, the sealing of the connection between the fixing belt and the corresponding plate body can be improved; on the other hand, when the fixing belt needs to be removed, the first slot portion can be used as a weak area at the connection between the fixing belt and the corresponding plate body to facilitate the removal of the fixing belt.
[0013] The two plates are arranged at intervals along the first direction, the gap between the two plates forms a first clearance groove, and the fixing belt covers the first clearance groove; the wiring harness isolation plate assembly also includes:
[0014] The two plates are connected by the convex ribs, which divide the first clearance groove into multiple window areas arranged along the second direction, and the second direction is arranged at an angle to the first direction; the fixing belt is bonded to the convex ribs. In this example, the two adjacent plates are connected by the convex ribs. On the one hand, it is convenient to set the two adjacent plates as a whole, thereby improving the convenience of processing; on the other hand, the convex ribs can block the gaps between adjacent battery cells in the battery module.
[0015] The convex rib has a weak area, which extends from one window area to another window area along the second direction, and the fixing belt is connected to the weak area. In this example, by setting the weak area on the fixing belt, when the fixing belt is removed from the plate body, the weak area can be disconnected to form a channel connecting two adjacent window areas.
[0016] The convex ribs include:
[0017] A first rib, the first rib having a first end and a second end, the first end of the first rib being connected to a plate body;
[0018] The second rib has one end connected to the second end of the first rib and the other end connected to the other plate; along the second direction, the width of the second rib is smaller than the width of the first rib, so that the second rib forms a weak area. In this example, the second rib forms a weak area of the convex rib, and the width of the second rib is smaller than the width of the first rib. When the fixing belt is torn off the convex rib, the fixing belt can tear off the second rib part, thereby forming a channel connecting two adjacent window areas.
[0019] The width of the second end of the first rib gradually decreases from the first rib to the second rib. In this example, by gradually reducing the width of the second end of the first rib, when the second rib is torn off, the tearing of the second end of the first rib is relatively smaller, and the integrity of the first rib can be maintained.
[0020] The length of the second rib along the first direction is smaller than that of the first rib. In this example, the length of the second rib is smaller than that of the first rib, so that when the second rib is torn off by the fixing tape, a narrower channel along the first direction can be formed.
[0021] Among them, along the second direction, the width of the first rib is not less than 5mm and not more than 10mm. In this example, by limiting the width of the first rib, the first rib does not occupy too much space, and at the same time, the width of the first rib is not too small, so that the first rib can connect to the second rib, so that the convex rib has a preset structural strength.
[0022] In the second direction, the width of the second rib is not less than 0.5 mm and not more than 2 mm. In this example, by limiting the width of the second rib, on the one hand, the second rib can form a weak area on the convex rib, and on the other hand, it can reduce the tearing of the first rib when the fixing belt is removed due to the second rib being too wide.
[0023] The convex ribs also include:
[0024] The third rib has one end connected to the end of the second rib away from the first rib, and the other end connected to the other plate; along the second direction, the width of the third rib is greater than the width of the second rib. The third rib in this example cooperates with the second rib, and the third rib and the second rib can cover the gap between the shoulders of adjacent battery cells in the battery module.
[0025] The width of the third rib near the second rib gradually decreases along the direction from the third rib to the second rib. In this example, by gradually reducing the width of the third rib near the second rib, the problem of the third rib being torn when the second rib is broken can be reduced.
[0026] Among them, along the first direction, the length of the second rib is less than the length of the third rib. In this example, by limiting the length of the second rib relative to the third rib, on the one hand, the second rib can be easily torn off, and on the other hand, the third rib can be used to cover the gap between the shoulders of adjacent battery cells in the battery module, reducing the risk of deformation or tearing of the third rib.
[0027] Wherein, along the second direction, the width of the third rib is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the third rib, the third rib does not occupy too much space, and at the same time, the width of the third rib is not too small, so that the third rib can connect to the second rib, so that the convex rib has a preset structural strength.
[0028] The third rib and the first rib are symmetrically arranged on both sides of the second rib along the first direction. In this example, by symmetrically arranging the first rib and the third rib, the processing of the convex rib can be facilitated.
[0029] The board body includes:
[0030] Two main bodies, the two main bodies are arranged at intervals along a first direction, and the gap between the two main bodies forms a first clearance groove; the convex rib is connected to the corresponding main body;
[0031] The film layer covers the two main parts and the first clearance groove, and the film layer forms a fixing belt at the position corresponding to the first clearance groove. In this example, the protective film covered on the board body is used as the film layer, and the film layer of the board body itself is used as the fixing belt. After the battery is installed, the film layer used as the fixing belt can be directly torn off, and there is no need to set up an additional fixing belt structure.
[0032] The film layer is bonded to the convex rib. In this example, the film layer can be directly torn off by bonding, and the film layer simultaneously drives the weak area on the convex rib to fall off.
[0033] The fixing belt includes:
[0034] A main body, detachably connected to at least one plate, with a fixing belt covering a gap between the two plates;
[0035] The clamping part is connected to at least one end of the main body along the length direction.
[0036] In this example, by providing a main body and a clamping portion, the main body can be used to cover the gap between adjacent battery modules, and the clamping portion can facilitate hand-holding or mechanical clamping when removing the fixing belt, so as to facilitate removing the fixing belt from the plate body.
[0037] The present application also proposes an example of a battery, comprising:
[0038] Two battery modules, the two battery modules are arranged adjacent to each other, the two battery modules respectively have a first surface, and the first surface is provided with a pole;
[0039] As in any of the above examples of the wiring harness isolation plate assembly, the two plates of the wiring harness isolation plate assembly are arranged one-to-one on the first surfaces of the two battery modules, and the fixing belt covers the gap between the two battery modules;
[0040] The sealing member is sealingly connected to the two battery modules and covers the gap between the two plates after the fixing belt is removed.
[0041] The battery in this example uses the above-mentioned wiring harness isolation plate assembly to connect adjacent battery modules. Since the wiring harness isolation plate assembly has a detachable fixing strap, the possibility of impurities entering the gap between adjacent battery modules can be reduced during the battery installation process; after the welding and other processes are completed, the gap between adjacent battery modules is sealed by a seal.
[0042] This application also proposes another example of a battery, including:
[0043] Two battery modules, the two battery modules are arranged adjacent to each other, the two battery modules respectively have a first surface, and the first surface is provided with a pole;
[0044] A wiring harness isolation plate assembly includes two plates, the two plates are spaced apart, and the two plates are arranged one-to-one on the first surfaces of the two battery modules;
[0045] The sealing member at least partially covers the gap between the two plates and is sealed and connected to the two battery modules.
[0046] In this example, by arranging the two plates of the wiring harness isolation plate one by one on the first surfaces of the two battery modules respectively, it is convenient to connect the poles of the battery cells of the two battery modules to the preset positions of the batteries; since a seal is provided, the seal can be used to seal the gap between the shoulders of the two battery modules to reduce the battery insulation failure caused by the overlap of the electrolyte across the modules.
[0047] The two plates are arranged at intervals along the first direction, and the gap between the two plates forms a first clearance groove; the wiring harness isolation plate assembly also includes:
[0048] The first rib has a first end and a second end, the first end of the first rib is connected to a plate body, and the second end of the first rib is extended in the direction of the other plate body; the first rib divides the first clearance groove to form a plurality of window areas arranged along the second direction; the gap between the second end of the first rib and the other plate body forms a second clearance groove connecting adjacent window areas; along the first direction, the length of the second clearance groove is less than the length of the first rib; the second direction is set at an angle to the first direction. In this example, by setting the first rib, on the one hand, the gap between the shoulders of adjacent battery cells in the battery module can be covered by the first rib; on the other hand, the second clearance groove between the first rib and the other plate body can form a channel connecting adjacent window areas to reduce the problem of insulation failure of the battery due to the large flow of electrolyte.
[0049] The width of the second end of the first rib gradually decreases from the first end to the second end of the first rib. In this example, the first rib can be easily formed by gradually decreasing the width of the second end of the first rib.
[0050] Wherein, along the second direction, the width of the first rib is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the first rib, the first rib does not occupy too much space, and at the same time, the width of the first rib is not too small, so that the convex rib has a preset structural strength.
[0051] Wherein, along the second direction, the width of the second clearance groove is not less than 0.5 mm and not more than 2 mm. In this example, by limiting the width of the second rib, the flow rate of the electrolyte can be reduced to reduce the problem of battery insulation failure caused by the flow of a large amount of electrolyte.
[0052] The battery also includes:
[0053] The third rib is arranged opposite to the first rib and connected to the other plate body, and a second clearance groove is formed between the end faces of the third rib and the first rib facing each other; along the first direction, the length of the second clearance groove is less than the length of the third rib. In this example, by arranging the third rib, on the one hand, it can be combined with the first rib to form a second clearance groove; on the other hand, the third rib can be used to cover the gap between the shoulders of adjacent battery cells.
[0054] Wherein, along the direction from the third rib to the first rib, the width of the third rib at one end close to the second make way groove gradually decreases. In this example, by gradually reducing the width of the end of the third rib, a second make way groove with a relatively small width is formed, so as to control the flow of electrolyte between adjacent window areas.
[0055] Wherein, along the second direction, the width of the third rib is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the third rib, the third rib does not occupy too much space, and at the same time, the width of the third rib is not too small, so that the convex rib has a preset structural strength.
[0056] The third rib and the first rib are symmetrically arranged on both sides of the second clearance groove along the first direction. In this example, the first rib and the third rib are symmetrically arranged to facilitate the processing of the convex rib.
[0057] Each battery module includes a plurality of battery cells, and the plurality of battery cells are adjacently arranged along the second direction, the first rib covers the gap between adjacent battery cells of one of the battery modules, the third rib covers the gap between adjacent battery cells of another battery module, and the seal is sealed and connected to the battery cells. In this example, by arranging the first rib and the third rib to correspond to the gap between the battery cells of the two battery modules, on the one hand, the flow of electrolyte between adjacent window areas can be reduced, and on the other hand, the sealing between adjacent battery cells can be improved to prevent foreign matter from entering the gap between adjacent battery cells.
[0058] Wherein, an adhesive layer is provided between the sealing member and the battery module. In this example, by providing the adhesive layer, the sealing member can be bonded and fixed to the battery module, which can improve the firmness of the sealing member on the one hand, and achieve a certain sealing effect on the other hand.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0075] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.
[0076] The multiple terms in the examples of this application refer to at least two (including two).
[0077] The technical solution described in the examples of this application is applicable to batteries and electrical equipment, which may be, but not limited to, mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft may include airplanes, rockets, space shuttles, and spacecraft, etc.
[0078] The battery generally includes a battery module, which may have one or more battery cells. The battery cells have poles. In order to facilitate the connection of the battery, in some cases, a wiring harness isolation plate may be provided on the battery module, and a bar may be provided on the wiring harness isolation plate. The bar may be a copper structure or an aluminum structure. The bar is used to connect the poles of the battery to electrically connect the battery to other electrical functional components on the battery module.
[0079] Under normal circumstances, the bar is usually connected to the pole by welding. During the fixation process of the wiring harness isolation plate and the bar, welding slag or other debris can easily enter the gap between adjacent battery modules, which can easily cause insulation failure and other problems in the battery module.
[0080] The example of the present application proposes a wiring harness isolation plate assembly, including a fixing belt and two plates, the two plates are arranged at intervals; the fixing belt is detachably connected to at least one plate, and the fixing belt covers the gap between the two plates. The two plates can be installed on two adjacent battery modules respectively, and the two plates can be respectively provided with grooves and other structures for installing the bar pieces to limit the bar pieces; through holes can be opened at the positions corresponding to the bar pieces on the two plates so that the poles of the battery cells can be connected to the corresponding bar pieces. The wiring harness isolation plate assembly in this example can also be provided with electrical structures such as flexible circuit boards for connecting the bar pieces. When connecting the bar piece and the pole, the fixing belt can block the gap between the two plates to prevent impurities such as welding slag generated by welding from entering the gap between adjacent battery modules; after the welding of the pole and the bar piece is completed, the fixing belt can be removed from the plate to facilitate subsequent sealing and other operations.
[0081] The wiring harness isolation plate in the example of the present application can be used for a battery, which may include at least two battery modules. The two plates of the wiring harness isolation plate assembly are respectively arranged corresponding to the two battery modules, so that the fixing belt of the wiring harness isolation plate assembly can cover the gap between the two battery modules.
[0082] The battery in the example of the present application can be used in an electrical device, and the electrical device can be the device described above.
[0083] See also Figure 1 In this example, the electric device 1000a is a vehicle. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle. A battery is provided inside the vehicle. The battery 100a can be provided at the bottom, head or tail of the vehicle. The vehicle can also include a driving device 200a and a control device 300a. The control device 300a is used to control the battery 100a to supply power to the driving device 200a, for example, for starting, navigating and driving the vehicle.
[0084] In some examples of the present application, the battery 100a can be used not only as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle. In some examples, the battery 100a can be an energy storage device. The energy storage device includes an energy storage container, an energy storage cabinet, etc.
[0085] See also Figure 2 The wiring harness isolation plate assembly in the example of the present application can be used for the battery 100a, and the battery 100a can include a box 50 and a battery cell 103, and the battery cell 103 or the battery 100a module is accommodated in the box 50. Among them, the box 50 is used to provide a storage space for the battery cell 103, and the box 50 can adopt a variety of structures. In some examples, the box 50 may include a first part 51 and a second part 52, and the first part 51 and the second part 52 cover each other, and the first part 51 and the second part 52 jointly define a storage space for accommodating the battery cell 103. The second part 52 can be a hollow structure with one end open, and the first part 51 can be a plate-like structure, and the first part 51 covers the open side of the second part 52, so that the first part 51 and the second part 52 jointly define a storage space; the first part 51 and the second part 52 can also be hollow structures with one side open, and the open side of the first part 51 covers the open side of the second part 52. Of course, the box 50 formed by the first part 51 and the second part 52 can be in various shapes, such as a cylinder, a cuboid, etc. In some examples, the box 50 can be used as a part of the chassis structure of the vehicle. For example, part of the box 50 can become at least a part of the floor of the vehicle, or part of the box 50 can become at least a part of the crossbeam and longitudinal beam of the vehicle.
[0086] In the battery 100a, there can be multiple battery cells 103, and the multiple battery cells 103 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 103 are both connected in series and in parallel. The multiple battery cells 103 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 103 is accommodated in the box 50; of course, the battery 100a can also be a battery 100a module formed by connecting multiple battery cells 103 in series, in parallel, or in mixed connection, and the multiple battery 100a modules are then connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the box 50. The battery 100a can also include other structures, for example, the battery 100a can also include a converging component for realizing electrical connection between the multiple battery cells 103.
[0087] See also Figure 3In some examples, a wiring harness isolation plate assembly 10 is disclosed, including a fixing belt 20 and two plates 11, and the two plates 11 are arranged at an interval; the fixing belt 20 is detachably connected to at least one plate 11, and the fixing belt 20 covers the gap between the two plates 11.
[0088] Please refer to Figure 4 , Figure 5 and Figure 6 , the plate body 11 can be used to cooperate with the battery module 101. A mounting position for installing a bar piece can be set on the plate body 11, and the mounting position can be a groove or other structure that can be used to limit the bar piece. Electrical components for connecting the bar piece, such as a flexible circuit board, etc., can also be set on the plate body 11 in the example of the present application. The battery module 101 has a first surface, and the pole 104 of the battery cell 103 in the battery module 101 is arranged on the same side as the first surface of the battery module 101. When the plate body 11 is installed on the battery module 101, the bar piece can be connected to the pole 104. Optionally, in this example, the bar piece can be connected to the pole 104 by welding or other methods.
[0089] There are two plates 11, and the two plates 11 correspond to two adjacently arranged battery modules 101. Since the shoulder on one side of the pole 104 of the battery cell 103 generally has a chamfer or other structure, a gap may be formed between the first surfaces of the two battery modules 101. The two plates 11 can be installed one-to-one on the two battery modules 101, so that the poles 104 on the battery cells 103 in the two battery modules 101 can be connected to the corresponding tabs.
[0090] The fixing belt 20 is detachably connected to at least one plate body 11, so that the fixing belt 20 can form an integral structure with at least one plate body 11, so as to facilitate the installation of the wiring harness isolation plate assembly 10. The fixing belt 20 in this example can be detachably connected to one of the plate bodies 11, and the fixing belt 20 in this example can also be detachably connected to two plate bodies 11 at the same time. For the convenience of description, in the following examples of this application, the fixing belt 20 is detachably connected to two plate bodies 11 at the same time as an example.
[0091] The fixing belt 20 covers the gap between the two plates 11, which means that the gap between the two plates 11 forms a first clearance groove 12, and the fixing belt 20 blocks the first clearance groove 12. The fixing belt 20 can partially fill the first clearance groove 12, and the fixing belt 20 can also cover the surface of the first clearance groove 12, so that the first clearance groove 12 is blocked by the fixing belt 20, and external impurities cannot move directly through the first clearance groove 12. In the example of the present application, the two plates 11 can be arranged at intervals along the first direction b, the width direction of the first clearance groove 12 extends along the first direction b, the length direction of the first clearance groove 12 can be the second direction c, and the first direction b and the second direction c can be arranged at an angle; optionally, the first direction b can be arranged perpendicular to the second direction c. The fixing belt 20 in the present application is detachably connected to the plate 11. When the wiring harness isolation plate assembly is installed, the fixing belt 20 can prevent impurities such as welding slag from entering the gap between adjacent battery modules 101, so as to reduce the problem of insulation failure of the battery module 101 caused by impurities. Since the fixing belt 20 is detachably connected to the plate body 11 , the fixing belt 20 can be removed after the installation of structures such as the tabs is completed, and the subsequent sealing operation between adjacent battery modules 101 can be conveniently performed.
[0092] The fixing belt 20 in this example is detachably connected, so that after the fixing belt 20 is removed, the first clearance groove 12 between the two plates 11 is opened, and when the battery module 101 is sealed, it can facilitate the seal 102 and the surface of the battery module 101 to fit each other, increase the sealing area between the seal 102 and the battery module 101, so that the seal 102 can be better sealed and connected with the battery module 101, reduce the electrolyte flow channel formed along the gap between adjacent battery modules 101, and thus reduce the problem of ignition caused by a large amount of electrolyte overlapping across the group. Optionally, in this example, an adhesive layer 1021 can be set between the seal 102 and the outer surface of the battery module 101 to bond the seal 102 to the surface of the battery module 101. Since the fixing belt 20 in this example is a detachable structure, after the fixing belt 20 is removed, the shoulder of the battery cell 103 of the battery module 101 can be exposed, so that the adhesive layer 1021 can contact the shoulder of the battery cell 103 more, thereby reducing the gap between the seal 102 and the battery cell 103 and improving the sealing performance of the seal 102.
[0093] See also Figure 6 The fixing belt 20 and the plate body 11 connected to the fixing belt 20 are integrally arranged. A first slot 23 is provided at the connection between the plate body 11 and the fixing belt 20. There are multiple first slots 23. The connecting line of the multiple first slots 23 forms a breaking line. The fixing belt 20 has a first end and a second end arranged along the length direction. The breaking line extends from the first end of the fixing belt 20 to the second end.
[0094] The fixing belt 20 and the plate body 11 connected to the fixing belt 20 are integrally arranged, which means that the fixing belt 20 and the plate body 11 connected thereto are an integral structure. A first slot 23 is provided at the connection between the fixing belt 20 and the corresponding plate body 11, so that a weak area is formed at the connection between the fixing belt 20 and the corresponding plate body 11. A plurality of first slots 23 extend from the first end to the second end along the length direction of the fixing belt 20, so that a plurality of first slots 23 form a breaking line, and the fixing belt 20 and the plate body 11 connected thereto can form a tearable structure. In this example, the fixing belt 20 can form a first slot 23 at the connection with one of the plate bodies 11, and overlap with the other plate body 11. In some examples, the fixing belt 20 and the two plate bodies 11 are both provided with the above-mentioned first slots 23 at the connection, so that the fixing belt 20 and the two plate bodies 11 form a tearable structure. In some examples, a first slot 23 is provided at the connection between the fixing belt 20 and one of the plates 11, so that a weak zone is formed at the connection between the fixing belt 20 and the plate 11, and the fixing belt 20 and the other plate 11 are bonded to each other, so that the fixing belt 20 can be torn off from the two plates 11. The first slot 23 in this example can be a slot structure with equal lengths, or a combination of slots with unequal lengths. The direction from the first end to the second end of the fixing belt 20 in the example of the present application can be the second direction c described above.
[0095] In this example, by using the first slot 23 to form a breaking line, the fixing belt 20 can be directly torn off the corresponding plate 11 when needed, so that the fixing belt 20 falls off the corresponding plate 11. Since the first slot 23 can form a weak area between the fixing belt 20 and the corresponding plate 11, when the fixing belt 20 is torn off the corresponding plate 11, the tearing of the plate 11 can be reduced. In this example, optionally, a plurality of first slots 23 can be arranged at intervals along the second direction c. Since a plurality of first slots 23 are used in this example, the fixing belt 20 and the corresponding plate 11 can have a connected portion, so that the fixing belt 20 can be processed integrally with the corresponding plate 11. When the first slot 23 is used at the connection between the fixing belt 20 and the two plate 11, the two plate 11 can be connected together by the fixing belt 20, so that the two plate 11 can form a whole. In the subsequent processing process, the two plate 11 can be installed on the two battery modules 101 at the same time to simplify the subsequent processing steps.
[0096] In some examples, the first slots 23 are through slots that penetrate the thickness direction of the fixing belt 20. In this example, the first slots 23 are through slots that penetrate the thickness direction of the fixing belt 20, and the area between adjacent first slots 23 connects the fixing belt 20 and the corresponding plate 11. By adopting the through slot structure, when the fixing belt 20 is removed from the corresponding plate 11, the possibility of the fixing belt 20 tearing the plate 11 can be reduced.
[0097] In some examples, the first slot 23 is a sunken slot arranged along the thickness direction of the fixing belt 20. In this example, the first slot 23 is a sunken slot in the thickness direction of the fixing belt 20, so that the thickness of the portion corresponding to the first slot 23 is reduced, and a weak area is formed at the position of the first slot 23, which makes it easier to tear, so that the connection portion between the fixing belt 20 and the corresponding plate body 11 is easier to disconnect. When the fixing belt 20 needs to be removed, the fixing belt 20 can be torn off along the first slot 23. Since the fixing belt 20 can be torn off along the extension direction of the breaking line, the tearing of the plate body 11 can be reduced, so as to reduce the possibility of damaging the plate body 11 when the fixing belt 20 is removed. In this example, the connection between the fixing belt 20 and the corresponding plate body 11 can be partially cut to form the first slot 23, and the thickness of the connection between the fixing belt 20 and the plate body 11 can be reduced when the fixing belt 20 and the corresponding plate body 11 are formed to form the first slot 23. In this example, the first groove 23 can be a recessed groove on one surface of the wiring harness isolation plate assembly in the thickness direction, or the first groove 23 can be provided on both surfaces of the wiring harness isolation plate assembly in the thickness direction, and the positions of the first grooves 23 on the two surfaces of the wiring harness isolation plate assembly in the thickness direction correspond to each other.
[0098] In some examples, the width d1 of the first slot 23 is not less than 0.1 mm and not more than 1 mm. In this example, the width of the first slot 23 is limited to not less than 0.1 mm to reduce the difficulty of opening the hole. In this example, since the width of the first slot 23 is limited to not more than 1 mm, the possibility of impurities passing through the first slot 23 can be reduced. In this example, the width d1 of the first slot 23 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, or any other value within the above range.
[0099] In some examples, the distance d2 between adjacent first slots 23 is not less than 0.5 mm and not more than 1.5 mm. In this example, by limiting the distance between adjacent first slots 23, on the one hand, the problem of the fixing belt 20 being easily detached from the corresponding plate 11 due to the small distance between adjacent first slots 23 can be reduced; on the other hand, the problem of the plate 11 being torn when the fixing belt 20 is removed due to the large distance between adjacent first slots 23 can be reduced. The distance d2 between adjacent first slots 23 in this example can be 0.5 mm, 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.3 mm or 1.5 mm, or any other value within the above range.
[0100] In some examples, the first slots 23 in any of the above examples are provided at the connection between the fixing belt 20 and the two plates 11, and the widths d1 of the first slots 23 at the connection between the fixing belt 20 and the two plates 11 may be equal or unequal. The distances d2 between adjacent first slots 23 at the connection between the fixing belt 20 and the two plates 11 may be equal or unequal.
[0101] In some examples, the fixing belt 20 and the plate body 11 connected to the fixing belt 20 are integrally arranged, and a first slot 23 is provided at the connection between the plate body 11 and the fixing belt 20, and the first slot 23 is a sunken slot provided along the thickness direction of the fixing belt 20; the fixing belt 20 has a first end and a second end provided along the length direction, and the first slot 23 extends from the first end to the second end of the fixing belt 20. In this example, the first slot 23 can be formed at the connection between the fixing belt 20 and the corresponding plate body 11, and the first slot 23 forms a weak area with a smaller thickness at the connection between the fixing belt 20 and the corresponding plate body 11, so as to facilitate tearing the fixing belt 20 from the corresponding plate body 11. In this example, the first slot 23 can be a sunken slot on one surface in the thickness direction of the wire harness isolation plate assembly, or the first slot 23 can be provided on both surfaces in the thickness direction of the wire harness isolation plate assembly, and the positions of the first slots 23 on the two surfaces in the thickness direction of the wire harness isolation plate assembly correspond to each other.
[0102] See also Figure 7 , Figure 8 and Fig. 9 In some examples, the two plates 11 are spaced apart along a first direction b, the gap between the two plates 11 forms a first clearance groove 12, and the fixing belt 20 covers the first clearance groove 12; the wiring harness isolation plate assembly 10 also includes a convex rib 30, the two plates 11 are connected by the convex rib 30, the convex rib 30 separates the first clearance groove 12 into a plurality of window areas 40 arranged along a second direction c, and the second direction c is arranged at an angle to the first direction b; the fixing belt 20 and the convex rib 30 are detachably connected.
[0103] Please refer to Fig.10 and Fig.11, the gap between the two plates 11 forms a first clearance groove 12, and the convex rib 30 in this example protrudes into the first clearance groove 12. The convex rib 30 connects the two plates 11 so that the two plates 11 are connected to form an integral structure. When installing the wiring harness isolation plate assembly, the wiring harness isolation plate assembly can be directly installed on the two battery modules as a whole. The fixing belt 20 is detachably connected to the convex rib 30, which means that the fixing belt 20 can be connected to the convex rib 30 so that the fixing belt 20 can maintain a preset position between the two plates 11, and the fixing belt 20 can also be removed from the convex rib 30. The fixing belt 20 in this example can also be bonded to one side edge of the two plates 11 close to the first clearance groove 12, so that the fixing belt 20 seals the gap between the two plates 11.
[0104] The convex ribs 30 separate the first clearance groove 12 to form a plurality of window areas 40 spaced apart along the second direction c. When the fixing belt 20 is removed from the plate body 11, the window areas 40 are exposed. When the battery module 101 is subsequently sealed, a colloidal substance may be filled in the window areas 40 so that the seal 102 can be better connected and fixed to the battery module 101. In this example, a plurality of convex ribs 30 may be provided, and the plurality of convex ribs 30 are spaced apart along the second direction c. The plurality of convex ribs 30 separate the first clearance groove to form a plurality of window areas 40 spaced apart along the second direction c. Under the obstruction of the convex ribs 30, the flow of electrolyte at the corresponding positions of the plurality of window areas 40 may be restricted to reduce the problem of ignition caused by the overlap of a large amount of electrolyte.
[0105] In the example of the present application, the first direction b and the second direction c are arranged at an angle, which means that the first direction b intersects the second direction c. Optionally, the first direction b described in the example may be perpendicular to the second direction c.
[0106] In some examples, the convex rib 30 has a weak area, which extends from one window area 40 to another window area 40 along the second direction c, and the fixing belt 20 is connected to the weak area. The weak area described in this example can be a thinner area on the convex rib 30, or a sudden change in width area on the convex rib 30. When the fixing belt 20 is torn off from the convex rib 30, the weak area can be broken, so that the corresponding position of the weak area can form a channel connecting two adjacent window areas 40. In this example, a cutting line as described in any of the above examples can also be set, and when the fixing belt 20 is torn off from the convex rib 30, the cutting line breaks.
[0107] In some examples, the convex rib 30 includes a first rib 31 and a second rib 32, the first rib 31 has a first end and a second end, the first end of the first rib 31 is connected to a plate body 11; the second rib 32 has one end connected to the second end of the first rib 31, and the other end connected to another plate body 11; along the second direction c, the width of the second rib 32 is smaller than the width of the first rib 31, so that the second rib 32 forms a weak area.
[0108] In this example, the first rib 31 is connected to one of the plates 11, and the second rib 32 can be used to connect the first rib 31 and the other plate 11. In this example, along the second direction c, the width of the second rib 32 is less than the width of the first rib 31. As the width decreases, a weak area is formed at the second rib 32. When the fixing belt 20 is torn off from the convex rib 30, the fixing belt 20 easily drives the second rib 32 to tear synchronously, thereby disconnecting the connection between the first rib 31 and the other plate 11. In this example, the second rib 32 with a reduced width along the second direction c is used to form a weak area, so that when the fixing belt 20 is removed, only the second rib 32 can be torn, so that a channel is formed between adjacent window areas 40, and the flow of electrolyte overflowing from the battery module 101 at the corresponding position of the adjacent window area 40 is limited by the first rib 31, so as to reduce the ignition problem caused by the overlap of a large amount of electrolyte. Since there is often a certain gap at the edge of the surface of the side where the pole 104 of the adjacent battery cell 103 is located, such as the gap formed by the chamfer of the edge of the side where the pole 104 of the battery cell 103 is located, the first rib 31 in this example can also be set corresponding to the gap between the shoulders of the adjacent battery cells 103 of the battery module 101, so that when the seal 102 is subsequently installed, the first rib 31 can be sealed in the gap between the shoulders of the adjacent battery cells 103 to reduce the flow of electrolyte. The width of the first rib 31 in this example along the second direction c can be adapted to the width of the gap between the end faces of the side where the pole 104 of the adjacent battery 100a in the battery module 101 is located, so that the first rib 31 can be used to cover the gap between the end faces of the side where the pole 104 of the adjacent battery 100a is located. Optionally, in this example, multiple first ribs 31 and second ribs 32 can be set, and each first rib 31 is set corresponding to a second rib 32. The first ribs 31 and the second ribs 32 separate the first clearance grooves into a plurality of window areas 40 spaced apart along the second direction c. Due to the shielding of the first ribs 31 , the flow of electrolyte between adjacent window areas 40 can be blocked.
[0109] In some examples, the width of the second end of the first rib 31 gradually decreases from the first rib 31 to the second rib 32. In this example, the width of the second end of the first rib 31 can be in an arc-shaped state of gradually decreasing from the first rib 31 to the second rib 32, or the width of the second end of the first rib 31 can be in a linear state of gradually decreasing. In this example, by gradually decreasing the width of the second end of the first rib 31, when the fixing belt 20 drives the second rib 32 to break, the second rib 32 is not likely to tear the first rib 31, thereby reducing damage to the first rib 31.
[0110] In some examples, along the first direction b, the length of the second rib 32 is less than the length of the first rib 31. In this example, by making the length of the second rib 32 in the first direction b less than the length of the first rib 31, the structural strength of the second rib 32 is relatively lower, and when the fixing belt 20 is removed, the second rib 32 can be disconnected synchronously while reducing damage to the first rib 31.
[0111] See also Fig. 9 In some examples, along the second direction c, the width d3 of the first rib 31 is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the first rib 31, the width of the first rib 31 can be within an appropriate range. On the one hand, it can reduce the excessive area occupied by the first rib 31 due to its excessive width, thereby reducing the problem of the small contact area between the seal 102 and the battery module 101 when the seal 102 is used for sealing later; on the other hand, it can reduce the problem of the first rib 31 easily falling off when the fixing belt 20 is disassembled due to the small width of the first rib 31; on the other hand, the first rib 31 can correspond to the gap position between adjacent battery cells 103 in the battery module 101, and in this example, the first rib 31 can be better adapted to the gap between adjacent battery cells 103. In this example, the width d3 of the first rib 31 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm or any other value within the above range.
[0112] In some examples, along the second direction c, the width of the second rib 32d4 is not less than 0.5 mm and not more than 2 mm. In this example, by limiting the width of the second rib 32 so that the width of the second rib 32 is within an appropriate range, on the one hand, the problem that the convex rib 30 cannot connect the two plates 11 due to the second rib 32 being too small can be reduced; on the other hand, the problem that the second rib 32 is not easy to break when the fixing belt 20 is disassembled due to the second rib 32 being too large can be reduced. In this example, the width d4 of the second rib 32 can be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm or any other value within the above range.
[0113] Please continue reading Fig. 9 In some examples, the convex rib 30 further includes a third rib 33, one end of the third rib 33 is connected to the end of the second rib 32 away from the first rib 31, and the other end is connected to the other plate 11; along the second direction c, the width of the third rib 33 is greater than the width of the second rib 32. In this example, the first rib 31, the second rib 32 and the third rib 33 form the convex rib 30, wherein the first rib 31 connects one of the plates 11, the third rib 33 connects the other plate 11, and the second rib 32 connects the first rib 31 and the third rib 33. In this example, by providing the third rib 33, the third rib 33 can be used as an intermediate connector between the second rib 32 and the other plate 11, so as to reduce the processing difficulty of the second rib 32. In this example, when the second rib 32 is broken, the third rib 33 can correspond to the gap position between the adjacent battery cells 103 of the battery module 101 on the corresponding side, so that the third rib 33 can be used to cover the gap on one side of the pole 104 of the adjacent battery cell 103. Since the second rib 32 is arranged between the first rib 31 and the third rib 33, when the second rib 32 is broken, a channel is formed between the end faces facing each other of the first rib 31 and the third rib 33. Under the shielding of the first rib 31 and the third rib 33, the area of the flow channel of the electrolyte at the corresponding position of the adjacent window area 40 can be reduced to reduce the overlap due to a large amount of electrolyte.
[0114] In some examples, the width of the third rib 33 at one end close to the second rib 32 gradually decreases along the direction from the third rib 33 to the second rib 32. In this example, the width of the third rib 33 can be in an arc-shaped state of gradually decreasing from the third rib 33 to the second rib 32, or the width of the third rib 33 can be in a linear state of gradually decreasing. In this example, by gradually decreasing the width of the third rib 33, when the fixing belt 20 is disassembled, the second rib 32 is disconnected, and the second rib 32 is not likely to tear the third rib 33, thereby reducing damage to the third rib 33.
[0115] In some examples, along the first direction b, the length of the second rib 32 is less than the length of the third rib 33. In this example, by making the length of the second rib 32 in the first direction b less than the length of the third rib 33, the structural strength of the second rib 32 is relatively lower, and when the fixing belt 20 is removed, the second rib 32 can be disconnected synchronously while reducing damage to the third rib 33.
[0116] See also Fig. 9In some examples, along the second direction c, the width d5 of the third rib 33 is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the third rib 33, the width of the third rib 33 can be within an appropriate range. On the one hand, the excessive area occupied by the third rib 33 due to its excessive width can be reduced, thereby reducing the problem of the small contact area between the seal 102 and the battery module 101 when the seal 102 is subsequently used for sealing; on the other hand, the problem of the third rib 33 easily falling off when the fixing belt 20 is disassembled due to the small width of the third rib 33 can be reduced; on the other hand, the third rib 33 can correspond to the gap position between adjacent battery cells 103 in the battery module 101, and in this example, the third rib 33 can be better adapted to the gap between adjacent battery cells 103. In this example, the width d5 of the third rib 33 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm or any other value within the above range.
[0117] See also Fig. 9 In some examples, the third rib 33 and the first rib 31 are symmetrically arranged on both sides of the second rib 32 along the first direction b. In this example, by symmetrically arranging the third rib 33 and the first rib 31, on the one hand, it is convenient to form the third rib 33 and the first rib 31 layer; on the other hand, the first rib 31 and the third rib 33 can respectively correspond to the gap between the battery cells 103 in the two battery modules 101, so as to prevent the electrolyte from flowing between the areas corresponding to the adjacent window areas 40.
[0118] In some examples, the plate body 11 includes two main bodies 21 and a film layer (not shown in the figure), the two main bodies 21 are arranged at intervals along the first direction b, and the gap between the two main bodies 21 forms a first clearance groove 12; the convex rib 30 is connected to the corresponding main body 21; the film layer covers the two main bodies 21 and the first clearance groove 12, and the film layer forms a fixing belt 20 at a position corresponding to the first clearance groove 12. The film layer described in this example can be a protective film connected to the surface of the main body 21. The two film layers form a fixing belt 20 at a position corresponding to the first clearance groove 12 between the two main bodies 21, and the fixing belt 20 can form the above-mentioned first slot 23 between the fixing belt 20 and the main body 21, and the fixing belt 20 can also be directly bonded to the above-mentioned second rib 32. In this example, the fixing belt 20 can be formed by the film layer of the harness isolation plate. After the harness isolation plate is installed on the battery module 101, when the structure such as the bar is welded and fixed, the fixing belt 20 can be blocked between the two main parts 21. The gap between the two battery modules 101 is blocked by the fixing belt 20, so that impurities such as welding slag cannot enter the gap between the two battery modules 101. After the installation of the harness isolation plate is completed, the film layer forming the fixing belt can be removed to facilitate the subsequent installation of sealing structures such as the seal 102, so as to facilitate the subsequent sealing of the gap between adjacent battery modules 101.
[0119] In some examples, the film layer is bonded to the convex rib 30 , and optionally, the film layer can be bonded to the second rib 32 , or the film layer can be bonded to the second rib 32 , the first rib 31 and the third rib 33 at the same time to improve the firmness of the film layer.
[0120] In some examples, the fixing belt 20 includes a main body 21 and a clamping portion 22. The main body 21 is detachably connected to at least one plate 11, and the fixing belt 20 covers the gap between the two plates 11. The main body 21 is connected to the clamping portion 22 at least at one end along the length direction. The main body 21 in this example can be used to connect the main body, and the clamping portion 22 can be used for hand-held or mechanical clamping. When the fixing belt 20 needs to be removed, the clamping portion 22 can be held by hand or clamped by mechanical equipment to remove the fixing belt 20 from the main body.
[0121] The present application also proposes an example of a battery 100a, comprising two battery modules 101, a wiring harness isolation plate assembly 10 as described in any of the above examples, and a seal 102, wherein the two battery modules 101 are arranged adjacent to each other, and the two battery modules 101 respectively have a first surface, and the first surface is provided with a pole 104; the two plate bodies 11 of the wiring harness isolation plate assembly 10 are arranged one-to-one on the first surfaces of the two battery modules 101, and the fixing belt 20 covers the gap between the two battery modules 101; the seal 102 is sealingly connected to the two battery modules 101, and covers the gap between the two plate bodies 11 after the fixing belt 20 is removed.
[0122] In this example, two battery modules 101 are arranged adjacent to each other, and the two plates 11 of the harness isolation plate assembly 10 are respectively installed on the first surface of the battery module 101 provided with the pole 104, so that the connection structure such as the bar can correspond to the position of the pole 104. When connecting the bar, the fixing belt 20 can be used to prevent impurities such as welding slag from entering the gap between adjacent battery modules 101 to reduce the problem of insulation failure of the battery module 101; in this example, after the fixing belt 20 is removed, the seal 102 can be connected to the two battery modules 101, so that the seal 102 seals the gap between the two battery modules 101, thereby reducing the possibility of the gap between the two battery modules 101 forming an electrolyte flow channel; the fixing belt 20 covers the gap between the two plates 11 to prevent foreign matter from entering between the adjacent battery cells 103 of the battery module 101 through the gap between the two plates 11.
[0123] It can be understood that the battery 100a in this example includes all the examples of the above-mentioned wiring harness isolation plate assembly 10, and also includes all the technical effects of the examples of the above-mentioned wiring harness isolation plate assembly 10, which will not be repeated.
[0124] Please refer to Figure 2 , Fig.10 and Fig.11 The present application also proposes an example of a battery 100a, including two battery modules 101, a wiring harness isolation plate and a seal 102, the two battery modules 101 are arranged adjacent to each other, and the two battery modules 101 respectively have a first surface, and the first surface is provided with a pole 104; the wiring harness isolation plate assembly 10 includes two plate bodies 11, the two plate bodies 11 are arranged at intervals, and the two plate bodies 11 are arranged one by one on the first surface of the two battery modules 101; the seal 102 at least partially covers the gap between the two plate bodies 11, and is sealed and connected to the two battery modules 101.
[0125] The two battery modules 101 are arranged adjacent to each other. In this example, the two battery modules 101 can be arranged adjacent to each other along the first direction b. The battery module 101 includes a plurality of battery cells 103, and the plurality of battery cells 103 can be arranged along the second direction c. Each battery cell 103 has a pole 104, and the poles 104 of the battery cells 103 of the two battery modules 101 are arranged on the first surface.
[0126] The wire harness isolation plate assembly 10 is mounted on the first surface of the battery module 101. The two plates 11 of the wire harness isolation plate assembly 10 are mounted one-to-one on the first surfaces of the two battery modules 101. The wire harness isolation plate assembly 10 can be installed with a connecting structure such as a bar, and the bar can be used to connect the pole 104 of the battery cell 103. The wire harness isolation plate assembly 10 in this example can also have an electrical element for connecting the bar, such as a flexible circuit board. The gap between the two plates 11 forms a first clearance groove 12, and the first clearance groove 12 corresponds to the gap between the first surfaces of the two battery modules 101.
[0127] The seal 102 is used to seal and connect the two battery modules 101. In this example, the seal 102 can be extended along the second direction c, and the seal 102 can be bonded to the battery module 101 so that the seal 102 seals the gap on one side of the first surface of the two battery modules 101. The seal 102 in this example can be used to block the flow of electrolyte to reduce the ignition problem caused by a large amount of electrode liquid overlapping across the group. The seal 102 at least partially covers the gap between the two plates 11, so that the seal 102 can block the gap between the two plates 11, thereby reducing impurities from entering between adjacent battery cells 103 through the gap between the two plates 11.
[0128] See also Fig.10 and Fig.11 In some examples, the two plates 11 are spaced apart along a first direction b, and the gap between the two plates 11 forms a first clearance groove 12; the wiring harness isolation plate assembly 10 also includes a first rib 31, the first rib 31 has a first end and a second end, the first end of the first rib 31 is connected to one plate 11, and the second end of the first rib 31 extends toward the other plate 11; the first rib 31 separates the first clearance groove 12 into a plurality of window areas 40 arranged along a second direction c; the gap between the second end of the first rib 31 and the other plate 11 forms a second clearance groove 34 connecting adjacent window areas 40; along the first direction b, the length of the second clearance groove 34 is less than the length of the first rib 31; the second direction c is arranged at an angle to the first direction b.
[0129] In this example, the first rib 31 is connected to one of the plates 11, and a second clearance groove 34 is formed between the first rib 31 and the other plate 11. The second clearance groove 34 can form a channel connecting the adjacent window areas 40, and the first rib 31 blocks the flow of electrolyte overflowing from the battery module 101 at the corresponding position of the adjacent window area 40, so as to reduce the ignition problem caused by the overlap of a large amount of electrolyte. Since there is often a certain gap at the edge of the surface of the side where the pole 104 of the adjacent battery cell 103 is located, such as the gap formed by the chamfer of the edge of the side where the pole 104 of the battery cell 103 is located, resulting in a gap between the shoulders of the adjacent battery cells 103, the first rib 31 in this example can also be set corresponding to the gap between the shoulders of the adjacent battery cells 103 of the battery module 101, so that when the seal 102 is subsequently installed, the first rib 31 can be sealed in the gap between the shoulders of the adjacent battery cells 103 to reduce the flow of electrolyte. The width of the first rib 31 along the second direction c in this example can be adapted to the width of the gap between the end faces on the side where the poles 104 of adjacent batteries 100a are located in the battery module 101, so that the first rib 31 can be used to block the gap between the end faces on the side where the poles 104 of adjacent batteries 100a are located. Optionally, multiple first ribs 31 can be set in this example. The first rib 31 separates the first clearance groove to form a plurality of window areas 40 spaced apart along the second direction c. In the example of this application, the first direction b and the second direction c are set at an angle, which means that the first direction b intersects with the second direction c. Optionally, the first direction b described in this example can be perpendicular to the second direction c.
[0130] In some examples, the width of the second end of the first rib 31 gradually decreases from the first end to the second end of the first rib 31. In this example, the width of the second end of the first rib 31 can be in an arc-shaped state of gradually decreasing from the first end to the second end of the first rib 31, or the width of the second end of the first rib 31 can be in a linear state of gradually decreasing. In this example, by gradually decreasing the width of the second end of the first rib 31, the molding of the first rib 31 can be facilitated.
[0131] In some examples, along the second direction c, the width d3 of the first rib 31 is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the first rib 31, the width of the first rib 31 can be within an appropriate range. On the one hand, it can reduce the excessive area occupied by the first rib 31 due to its excessive width, thereby reducing the problem of the small contact area between the seal 102 and the battery module 101 when the seal 102 is used for sealing later; on the other hand, it can reduce the problem of the first rib 31 being easy to fall off when the fixing belt 20 is disassembled due to the small width of the first rib 31; on the other hand, the first rib 31 can correspond to the gap position between adjacent battery cells 103 in the battery module 101, and in this example, the first rib 31 can be better adapted to the gap between adjacent battery cells 103. In this example, the width d3 of the first rib 31 may be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm or any other value within the above range.
[0132] In some examples, along the second direction c, the width of the second clearance groove 34 is not less than 0.5 mm and not more than 2 mm. In this example, the width of the second clearance groove 34 is limited so that the width of the second clearance groove 34 is within an appropriate range. In this example, the width of the second rib 32 can be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm or any other value within the above range.
[0133] In some examples, the battery 100a further includes a third rib 33, which is arranged opposite to the first rib 31 and connected to the other plate 11, and a second clearance groove 34 is formed between the end faces of the third rib 33 and the first rib 31 facing each other; along the first direction b, the length of the second clearance groove 34 is less than the length of the third rib 33. The third rib 33 in this example can be arranged opposite to the first rib 31, and the first rib 31, the second rib 32 and the third rib 33 in this example form a convex rib 30, wherein the first rib 31 is connected to one of the plates 11, the third rib 33 is connected to the other plate 11, and a second clearance groove 34 is formed between the first rib 31 and the third rib 33. The third rib 33 in this example can correspond to the gap position between the adjacent battery cells 103 of the battery module 101 on the corresponding side, so that the third rib 33 can be used to cover the gap on one side of the pole 104 of the adjacent battery cell 103. The second clearance groove 34 between the facing end surfaces of the first rib 31 and the third rib 33 forms a channel. Under the shielding of the first rib 31 and the third rib 33, the area of the flow channel of the electrolyte at the corresponding position of the adjacent window area 40 can be reduced to reduce the overlap due to a large amount of electrolyte.
[0134] In some examples, the width of the third rib 33 at one end close to the second clearance groove gradually decreases along the direction from the third rib 33 to the first rib 31. In this example, the width of the third rib 33 can be in an arc-shaped state of gradually decreasing from the third rib 33 to the first rib 31, or the width of the third rib 33 can be in a linear state of gradually decreasing. In this example, the width of the third rib 33 is gradually reduced to facilitate the formation of the third rib 33.
[0135] In some examples, along the second direction c, the width of the third rib 33 is not less than 5 mm and not more than 10 mm. In this example, by limiting the width of the third rib 33, the width of the third rib 33 can be within an appropriate range. On the one hand, it can reduce the problem that the third rib 33 occupies too large an area due to the third rib 33 being too large, and then the contact area between the seal 102 and the battery module 101 is too small when the seal 102 is used for sealing later; on the other hand, it can reduce the problem that the third rib 33 is easy to fall off when the fixing belt 20 is disassembled due to the third rib 33 being too small; on the other hand, the third rib 33 can correspond to the gap position between adjacent battery cells 103 in the battery module 101. In this example, the third rib 33 can be better adapted to the gap between adjacent battery cells 103. In this example, the width d5 of the third rib 33 may be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm or any other value within the above range.
[0136] In some examples, the third rib 33 and the first rib 31 are symmetrically arranged on both sides of the second clearance groove along the first direction b. In this example, by symmetrically arranging the third rib 33 and the first rib 31, on the one hand, it is convenient to form the third rib 33 and the first rib 31 layer; on the other hand, the first rib 31 and the third rib 33 can respectively correspond to the gap between the battery cells 103 in the two battery modules 101, so as to prevent the electrolyte from flowing between the areas corresponding to the adjacent window areas 40.
[0137] Please refer to Figure 2In some examples, each battery module 101 includes a plurality of battery cells 103, and the plurality of battery cells 103 are arranged adjacent to each other. The first rib 31 covers the gap between the adjacent battery cells 103 of one of the battery modules 101, and the third rib 33 covers the gap between the adjacent battery cells 103 of another battery module 101. The seal 102 is sealed and connected to the battery cell 103. The battery cell 103 has a pole 104, and the wire harness isolation plate assembly 10 is arranged on one side of the end surface corresponding to the battery cell 103 provided with the pole 104, so that the electrical structure such as the bar can be installed on the wire harness isolation plate assembly 10. The first rib 31 and the third rib 33 are arranged corresponding to the two groups of battery modules 101, so that the first rib 31 and the third rib 33 can cover the gap between the battery cells 103. The shoulders of some battery cells 103 on the side where the pole 104 is arranged are chamfered. The first rib 31 and the third rib 33 can be arranged corresponding to the chamfered parts of the shoulders of adjacent battery cells 103 to reduce the possibility of impurities entering the gaps between adjacent battery cells 103.
[0138] Please refer to Figure 2 In some examples, an adhesive layer 1021 is provided between the seal 102 and the battery module 101. The adhesive layer 1021 in this example may be a colloid filled in the adjacent window area 40, or may be a colloid provided on the surface of the seal 102, and the seal 102 and the outer surface of the battery module 101 are bonded to each other through the adhesive layer 1021, so that the seal 102 can seal the gap between the adjacent battery modules 101, thereby reducing the ignition problem caused by the large flow of electrolyte.
[0139] The present application also discloses an example of an electric device 1000a, including a battery 100a as described in any of the above examples, and the battery 100a is used to provide electric energy for the electric device 1000a. The electric device 1000a in this example can be the vehicle or other tool described above. The battery 100a described in this example can be used to provide kinetic energy for the electric device 1000a, and can also be used to provide power for the electrical structure on the electric device 1000a.
[0140] Please refer to Figures 1 to 11The example of the present application discloses a wire harness isolation plate assembly 10, including a fixing belt 20 and two plates 11, the two plates 11 are arranged at intervals; the fixing belt 20 is detachably connected to at least one plate 11, and the fixing belt 20 covers the gap between the two plates 11. In this example, a first slot 23 can be provided at the connection between the fixing belt 20 and the plate 11, so that a weak area is formed at the connection between the fixing belt 20 and the plate 11. When the fixing belt 20 is removed from the plate 11, the position of the fixing belt 20 and the plate corresponding to the first slot 23 can be disconnected, thereby causing the fixing belt 20 to fall off the plate 11. The fixing belt 20 in this example can also be bonded to the plate 11. The gap between the two plates 11 forms a first clearance groove 12. The two plates 11 are connected by a convex rib 30 so that the two plates 11 form an integral structure, which is convenient for subsequent installation. The convex rib 30 separates the first clearance groove between the two plates 11 to form a plurality of window areas 40 along the second direction c; the fixing belt 20 can be bonded to the convex rib 30 so that the fixing belt 20 can be directly torn off from the plate 11; the convex rib 30 in this example can include a first rib 31 and a second rib 32, wherein the second The width of the rib 32 along the second direction c can be smaller than the width of the first rib 31 along the second direction c, so that the second rib 32 forms a weak area of the convex rib 30. When the fixing belt 20 is removed, the fixing belt 20 drives the second rib 32 to break, so that the second rib 32 forms a second clearance groove 34 connecting the adjacent window area 40. Due to the obstruction of the first rib 31, the electrolyte at the corresponding position of the adjacent window area 40 will not flow in large quantities, thereby reducing the ignition caused by the large flow of electrolyte. In this example, a third rib 33 can also be set at the position corresponding to the first rib 31. The third rib 33 is arranged opposite to the first rib 31, and a second clearance groove 34 is formed between the first rib 31 and the third rib 33 to form a channel connecting the adjacent window areas 40. The first rib 31 and the third rib 33 can simultaneously play a role in blocking the flow of electrolyte, thereby reducing the large amount of electrolyte flowing across the area. The present application also discloses a battery 100a, which includes two battery modules 101 arranged along a first direction b, a wiring harness isolation plate assembly 10, and a seal 102. The battery module 101 has a pole 104. The wiring harness isolation plate assembly 10 is arranged on a side end face of the battery module 101 provided with the pole 104. The wiring harness isolation plate assembly 10 can be used to install structures such as a bar. The seal 102 is used to seal the gap between adjacent battery modules 101. The seal 102 can also be used to seal the gap between two adjacent plates 11 of the wiring harness isolation plate assembly 10.
