Description

Technical Field

[0001] This disclosure relates to the field of battery module technology, and in particular to an integrated battery cell harness fixing device and a battery module. Background Technology

[0002] With the rapid development of the new energy industry, battery modules, as a core component of power battery systems, are directly affected by the layout and fixing scheme of their internal wiring harnesses, which in turn impacts their safety, reliability, and production efficiency. Currently, battery modules typically integrate wiring harnesses with multiple functions, including high-voltage charging / discharging lines, voltage acquisition lines, communication lines, and heating lines. As the integration level of battery modules continues to increase, the number of battery cells rises, and space becomes increasingly compact, leading to a corresponding increase in the number of wiring harnesses. Ensuring the orderly and reliable wiring of these harnesses within the limited space of the battery module has become a pressing technical challenge in this field.

[0003] In existing technologies, the wiring harness layout and fixing of battery modules generally adopts the method of pre-drilling tying holes on structural components and using a large number of nylon cable ties for subsequent binding and fixing. This method has the defects of random and messy wiring harness routing, still relying on the skill of operators to manually arrange and bind the wiring harness, resulting in poor quality consistency. Secondly, the sharp ends left after the cable ties are cut may wear down the insulation layer of the wiring harness under vibration conditions, posing a significant safety hazard. Furthermore, the extensive use of cable ties increases material and management costs, and the excessively long cables reserved for the pursuit of wiring flexibility further increase the cost of the wiring harness. Moreover, the assembly process requires repeated arrangement, threading, and binding of the wiring harness, making the process cumbersome and time-consuming, resulting in low assembly efficiency. In addition, during maintenance, the cable ties must be cut one by one to remove the target wiring harness, and after maintenance, it is difficult to restore it to its original neat state, which is inconvenient for the maintenance of the wiring harness.

[0004] Therefore, there is an urgent need for a battery module wiring solution that is well-organized, allows for rapid installation, is convenient and safe, easy to maintain, and is neat and aesthetically pleasing. Summary of the Invention

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an integrated battery cell harness fixing device and battery module that features neat wiring, enables rapid installation, eliminates the need for cable ties to bundle the wire harness, is convenient and safe to install, and is easy to maintain.

[0006] The purpose of this disclosure is achieved through the following technical solution: An integrated battery cell harness fixing device includes: a bracket housing, the bracket housing having at least one battery cell mounting portion, the battery cell mounting portion having a plurality of spaced-apart battery cell mounting slots, each battery cell mounting slot for mounting one battery cell; the bracket housing also having an embedded wire-locking slot, the extension direction of the embedded wire-locking slot being parallel to the arrangement direction of the plurality of battery cell mounting slots, and the embedded wire-locking slot being disposed adjacent to the end of each battery cell mounting slot; a battery cell row gap is formed between each pair of adjacent battery cell mounting slots, and each battery cell row gap is in communication with the embedded wire-locking slot; The wire harness outlet is connected to the bracket housing and is located at one end of the embedded wire slot. The periphery of the wire harness outlet is provided with a wire harness receiving notch that communicates with the embedded wire slot. The wire harness receiving notch is used to pass through the ends of multiple wire harness components, and at least one of the wire harness components is interference-fitted into the wire harness receiving notch. Some of the wire harness components are sequentially disposed in the adjacent gaps between the battery cells and the embedded wire slots and extend to the wire harness receiving opening, while other parts of the wire harness components are disposed in the embedded wire slots and extend to the wire harness receiving opening.

[0007] In one embodiment, there are two cell mounting portions, and the arrangement direction of the two cell mounting portions intersects with the arrangement direction of the plurality of cell mounting slots in each cell mounting portion. A cell row gap is formed between two adjacent cell mounting slots in each cell mounting portion. There are two embedded wire-locking slots, and the two embedded wire-locking slots are arranged one-to-one with the two cell mounting portions. Each cell row gap is connected to the corresponding embedded wire-locking slot, and each embedded wire-locking slot is located between two cell mounting portions. The wire harness outlet is located at one end of each embedded wire-locking slot, and the wire harness receiving notch is connected to the end of each embedded wire-locking slot. Some of the wire harness components are sequentially arranged in adjacent cell row gaps and adjacent embedded wire-locking slots and extend to the wire harness receiving notch, while other parts of the wire harness components are arranged in another embedded wire-locking slot and extend to the wire harness receiving notch.

[0008] In one embodiment, there are multiple cell mounting portions, and the arrangement direction of the multiple cell mounting portions intersects with the arrangement direction of the multiple cell mounting slots of each cell mounting portion. A cell row gap is formed between two adjacent cell mounting slots of each cell mounting portion. There are two embedded cable slots, each corresponding to any two adjacent cell mounting portions. Each embedded cable slot communicates with its corresponding cell row gap, and each embedded cable slot corresponds to two cell mounting portions. In the remaining cell mounting portions, the multiple cell row gaps of each cell mounting portion communicate with adjacent... The multiple cell row gaps of the other cell mounting part are connected one-to-one; the wire harness outlet is located at one end of each of the embedded wire slots, and the wire harness receiving notch is connected to the end of each of the embedded wire slots; some of the wire harness components are sequentially arranged in adjacent cell row gaps and adjacent embedded wire slots and extend to the wire harness receiving notch, another part of the wire harness components are sequentially arranged in adjacent cell row gaps, at least one corresponding cell row gap, and adjacent embedded wire slots and extend to the wire harness receiving notch, and yet another part of the wire harness components are arranged in the embedded wire slots and extend to the wire harness receiving notch.

[0009] In one embodiment, a wire bonding operation groove is provided between two adjacent battery cell mounting slots, and each wire bonding operation groove is located at the end of the corresponding battery cell mounting slot; an electrical connection piece is also provided on the bracket housing, the electrical connection piece is disposed in the wire bonding operation groove, and the wire harness adjacent to the wire bonding operation groove is electrically connected to the electrical connection piece.

[0010] In one embodiment, each of the embedded wire-locking slots includes at least one first wire-locking protrusion and at least one second wire-locking protrusion disposed opposite to each other, with a wire-locking gap formed between the first wire-locking protrusion and the second wire-locking protrusion; the corresponding wire harness is snapped into the wire-locking gap and clamped and fixed by the first wire-locking protrusion and the second wire-locking protrusion.

[0011] In one embodiment, the bracket housing is further provided with at least one sensor mounting post, each sensor mounting post having a mounting positioning groove for mounting a sensor, each sensor being fixedly connected to the corresponding sensor mounting post, and the sensor being connected to an adjacent wiring harness.

[0012] In one embodiment, the embedded cable slot is integrally formed with the bracket housing.

[0013] In one embodiment, the mounting positioning groove is integrally formed with the bracket housing.

[0014] In one embodiment, the wire harness outlet has an embedded wire protection cavity formed on the side facing the battery cell mounting portion, the embedded wire protection cavity being configured to avoid misalignment with at least a portion of the wire harness component.

[0015] In one embodiment, the wire harness outlet is further provided with a visual anti-mistake hole, and the location of the visual anti-mistake hole is set opposite to the location of the embedded wire protection cavity.

[0016] A battery module includes the integrated cell harness fixing device described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages: 1) The bracket housing is provided with at least one cell mounting part, and the cell mounting part has a plurality of spaced cell mounting slots. Each cell mounting slot is used to mount one cell. A cell row gap is formed between each two adjacent cell mounting slots. Each cell row gap is connected to the embedded wire slot so that each cell row gap forms a wiring path. This ensures that the wire harness is radially limited in the cell row gap. The cell row gap serves as a branch wiring channel for the wire harness, allowing the wire harness to be directly inserted into the cell row gap and extend to the wire harness outlet. This ensures that the wiring layout of the wire harness is neat and the structure is compact. Furthermore, the bracket housing is also equipped with embedded wire-clamping grooves. The extension direction of the embedded wire-clamping grooves is parallel to the arrangement direction of the multiple battery cell mounting slots, and the embedded wire-clamping grooves are located adjacent to the end of each battery cell mounting slot. This ensures that during assembly, the wire harness components are clamped and installed along the preset gap between battery cells and the arrangement of the embedded wire-clamping grooves, which provides better constraint protection for the wire harness components and effectively avoids the risk of entanglement and friction between the wire harness components. This creates a pre-set wiring path for the wire harness components with neat wiring on the bracket housing, ensuring accurate and reliable installation of each wire harness component. In this way, one-step installation of alignment, embedding, and clamping of the wire harness components is achieved without the need for binding operations, which greatly improves the assembly efficiency of the wire harness components.

[0018] 2) Since the wire harness outlet is connected to the bracket housing and is located at one end of the embedded wire slot, it forms a convergence channel for the wire harness components. This allows each wire harness component to converge along the embedded wire slot to the wire harness outlet, ensuring a short convergence path. The embedded wire slot in the bracket housing secures the wire harness components, preventing cross-entanglement during convergence and avoiding signal interference and friction risks caused by disordered interweaving, thus reducing safety hazards. Furthermore, there is no need to use cable ties for binding and fixing, resulting in a clearer and more standardized overall layout of the wire harness components, facilitating later inspection and maintenance. Maintenance can be performed simply by pulling the wire harness component requiring repair out of the corresponding cell array gap, without the need for destructive disassembly.

[0019] 3) Since the periphery of the wire harness outlet is provided with a wire harness receiving notch that communicates with the embedded wire slot, the wire harness receiving notch is used to pass through the ends of multiple wire harness components. This ensures that after the wire harness component is led out through the embedded wire slot, it can be directly passed through the wire harness receiving notch. The operator can directly insert the wire harness component from the opening of the wire harness receiving notch without having to pass it through the hole, which improves the assembly efficiency of the wire harness component. In addition, at least one of the wire harness components is interference-fitted into the wire harness receiving notch, which effectively prevents the wire harness component from shifting or moving during subsequent assembly.

[0020] 4) Since some of the wire harness components are sequentially arranged in the adjacent gaps between the battery cells and the embedded wire clamping slots and extend to the wire harness receiving opening, and other wire harness components are arranged in the embedded wire clamping slots and extend to the wire harness receiving opening, it is ensured that each gap between the battery cells and the embedded wire clamping slots clamp and install each wire harness component along the wiring path of each wire harness component, ensuring that the wire harness components are well constrained and protected. A neat wire harness channel is formed on the bracket housing, and it is further ensured that each wire harness component converges to the wire harness receiving opening with a shorter path. This effectively shortens the length of each wire harness component, thereby reducing the amount of wire used, reducing the material cost of the wire harness components, and significantly improving the assembly efficiency of the wire harness components.

[0027] This disclosure provides an integrated battery cell harness fixing device, comprising: a bracket housing, the bracket housing having at least one battery cell mounting portion, the battery cell mounting portion having a plurality of spaced-apart battery cell mounting slots, each battery cell mounting slot for mounting one battery cell; the bracket housing also having an embedded wire-locking slot, the extension direction of the embedded wire-locking slot being parallel to the arrangement direction of the plurality of battery cell mounting slots, and the embedded wire-locking slot being disposed adjacent to the end of each battery cell mounting slot; a battery cell row gap is formed between each pair of adjacent battery cell mounting slots, and each battery cell row gap is in communication with the embedded wire-locking slot; The wire harness outlet is connected to the bracket housing and is located at one end of the embedded wire slot. The periphery of the wire harness outlet is provided with a wire harness receiving notch that communicates with the embedded wire slot. The wire harness receiving notch is used to pass through the ends of multiple wire harness components, and at least one of the wire harness components is interference-fitted into the wire harness receiving notch. Some of the wire harness components are sequentially disposed in the adjacent gaps between the battery cells and the embedded wire slots and extend to the wire harness receiving opening, while other parts of the wire harness components are disposed in the embedded wire slots and extend to the wire harness receiving opening.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1-9 This disclosure provides an integrated battery cell harness fixing device 10, including a bracket housing 110 and a harness outlet 120. The bracket housing 110 is provided with at least one battery cell mounting part 112. The battery cell mounting part 112 has a plurality of spaced-apart battery cell mounting slots 1121, each of which is used to mount a battery cell 30. A battery cell row gap 1122 is formed between each two adjacent battery cell mounting slots 1121. Each battery cell row gap 1122 communicates with the embedded wire clamping slot 1123 so that each battery cell row gap 1122 forms a wiring path, ensuring that the harness component 130 is radially limited in the battery cell row gap 1122. The battery cell row gap 1122 serves as a branch wiring channel for the harness component 130, allowing the harness component 130 to directly pass through the battery cell row gap 1122 and extend to the harness outlet 120, ensuring that the wiring layout of the harness component 130 is neat and the structure is compact.

[0029] Please see Figure 4 It is understood that, since the bracket housing 110 is also provided with an embedded wire-locking groove 1123, the extension direction of the embedded wire-locking groove 1123 is parallel to the arrangement direction of the plurality of battery cell mounting slots 1121, and the embedded wire-locking groove 1123 is set adjacent to the end of each battery cell mounting slot 1121, so as to ensure that during assembly, the wire harness 130 is locked and installed along the preset battery cell row gap 1122 and the embedded wire-locking groove 1123, which forms a good constraint protection for the wire harness 130, and better avoids the risk of entanglement and friction between the wire harnesses 130. Thus, a pre-set wiring path of the wire harness 130 with neat wiring is formed on the bracket housing 110, ensuring the accurate and reliable installation of each wire harness 130. In this way, the one-step installation of the alignment, embedding and locking of the wire harness 130 is realized without the need for binding operation, which greatly improves the assembly efficiency of the wire harness 130.

[0030] It can also be understood that, since the wire harness outlet 120 is connected to the bracket housing 110 and the wire harness outlet 120 is located at one end of the embedded wire clamping groove 1123, a central gathering channel for the wire harness components 130 is formed. This allows each wire harness component 130 to gather along the embedded wire clamping groove 1123 to the wire harness outlet 120, ensuring a short gathering path for the wire harness components 130. The embedded wire clamping groove 1123 in the bracket housing 110 enables the clamping and installation of the wire harness components 130, avoiding cross-entanglement of the wire harnesses during the gathering process to the wire harness outlet 120. This avoids signal interference and friction risks caused by disordered interweaving of the wire harness components 130, reducing safety hazards. At the same time, there is no need to use cable ties for binding and fixing, making the overall layout of the wire harness components 130 clearer and more standardized, which is convenient for later inspection and maintenance. Only the wire harness component 130 to be repaired needs to be pulled out from the corresponding cell array gap 1122 for maintenance, without the need for destructive disassembly.

[0031] Specifically, since the periphery of the wire harness outlet 120 is provided with a wire harness receiving notch 121 that communicates with the embedded wire slot 1123, the wire harness receiving notch 121 is used to pass through the ends of multiple wire harness components 130, so as to ensure that after the wire harness component 130 is led out through the embedded wire slot 1123, it can be directly passed through the wire harness receiving notch 121. The operator can directly insert the wire harness component 130 from the opening of the wire harness receiving notch 121 without passing it through the through hole, which improves the assembly efficiency of the wire harness component 130. Moreover, at least one of the wire harness components 130 is interference-fitted into the wire harness receiving notch 121, which effectively prevents the wire harness component 130 from shifting or moving during subsequent assembly. Furthermore, since some of the wire harness components 130 are sequentially arranged in the adjacent cell busbar gaps 1122 and the embedded wire-clamping grooves 1123 and extend to the wire harness receiving opening 121, and other wire harness components 130 are arranged in the embedded wire-clamping grooves 1123 and extend to the wire harness receiving opening 121, it is ensured that each cell busbar gap 1122 and the embedded wire-clamping groove 1123 clamps and installs each wire harness component 130 along the wiring path of each wire harness component 130, ensuring that the wire harness component 130 is well constrained and protected. A neat wire harness channel is formed on the bracket housing 110, and it is further ensured that each wire harness component 130 converges to the wire harness receiving opening 121 with a shorter path, effectively shortening the length of each wire harness component 130, thereby reducing the amount of wire used, reducing the material cost of the wire harness component 130, and significantly improving the assembly efficiency of the wire harness component 130.

[0032] Please see Figure 2In one embodiment, there are two cell mounting portions 112, and the arrangement direction of the two cell mounting portions 112 intersects with the arrangement direction of the plurality of cell mounting slots 1121 of each cell mounting portion 112. A cell row gap 1122 is formed between two adjacent cell mounting slots 1121 of each cell mounting portion 112. There are two embedded wire-locking slots 1123, and the two embedded wire-locking slots 1123 are arranged one-to-one with the two cell mounting portions 112. Each cell row gap 1122 communicates with the corresponding embedded wire-locking slot 1123, and each embedded wire-locking slot 1123 is located between two cell mounting portions 112. The wire harness outlet 120 is located at one end of each embedded wire-locking slot 1123, and the wire harness receiving notch 121 communicates with the end of each embedded wire-locking slot 1123. Some of the wire harness components 130 are sequentially arranged on adjacent cell rows. The wire harness components 130 are disposed in the gap 1122 and the adjacent embedded wire slot 1123 and extend to the wire harness receiving notch 121. Another portion of the wire harness components 130 are disposed in another embedded wire slot 1123 and extend to the wire harness receiving notch 121. When the two cell mounting portions 112 are arranged side-by-side, each wire harness component 130 converges and passes through the adjacent cell row gap 1122 into the embedded wire slot 1123 between the two cell mounting portions 112 to form a wire harness component 13. The wire harness receiving channel converges towards the center, thereby forming a pre-defined wiring path for the wire harness 130 on the bracket housing 110, ensuring the accurate and reliable installation of each wire harness 130. The clearly planned pre-defined wiring path allows operators to install the wire harness 130 more easily and quickly. They only need to insert the wire harness 130 along the embedded wire clip and embedded wire clip groove 1123 and extend it to the wire harness receiving notch 121, thereby improving the assembly efficiency of the wire harness 130.

[0033] It is understood that, since the wire harness outlet 120 is located at one end of each of the embedded wire slots 1123, and the wire harness receiving notch 121 is connected to the end of each of the embedded wire slots 1123, the wire harness component 130 is centrally passed out and connected to the outside. At the same time, the wire harness components 130 in the two cell mounting parts 112 are symmetrically distributed in the preset wiring paths. Some wire harnesses run along the gap 1122 between the cell rows on one side and the wire slot, while other wire harnesses run along the wire slot on the other side. Finally, they converge at the same wire harness receiving notch 121, thereby ensuring that the wire harness components 130 in the two cell mounting parts 112 are installed symmetrically and aesthetically, and the wiring is neat.

[0034] It is also understandable that, since the two cell mounting parts 112 make the functions of each individual cell mounting part 112 relatively independent, when the wiring harness 130 of one cell mounting part 112 needs to be repaired or replaced, only that cell mounting part 112 needs to be disassembled and reassembled, without affecting the assembly status of the other cell mounting part 112.

[0035] In one embodiment, there are multiple battery cell mounting portions 112, and the arrangement direction of the multiple battery cell mounting portions 112 intersects with the arrangement direction of the multiple battery cell mounting slots 1121 of each battery cell mounting portion 112. A battery cell row gap 1122 is formed between two adjacent battery cell mounting slots 1121 of each battery cell mounting portion 112. There are two embedded wire-locking slots 1123, each corresponding to any two adjacent battery cell mounting portions 112. Each embedded wire-locking slot 1123 communicates with each corresponding battery cell row gap 1122, and each embedded wire-locking slot 1123 corresponds to two battery cell mounting portions 112. In the remaining battery cell mounting portions 112, the multiple battery cell row gaps 1122 of each battery cell mounting portion 112 are correspondingly connected to the multiple battery cell row gaps 1122 of another adjacent battery cell mounting portion 112. The wire harness guide... The outlet 120 is located at one end of each of the embedded cable slots 1123, and the wire harness receiving notch 121 communicates with the end of each of the embedded cable slots 1123; some of the wire harness components 130 are sequentially disposed in adjacent cell bus gaps 1122 and adjacent embedded cable slots 1123 and extend to the wire harness receiving notch 121, and other parts of the wire harness components 130 are sequentially disposed in adjacent cell bus gaps 1122, corresponding to at least one cell bus gap. The battery cell array gap 1122 and the adjacent embedded wire slot 1123 extend to the wire harness receiving notch 121. A portion of the wire harness components 130 are also disposed in the embedded wire slot 1123 and extend to the wire harness receiving notch 121. This ensures that when multiple battery cell mounting parts 112 are combined, a pre-set wiring path for the wire harness components 130 can still be formed, ensuring the accurate and reliable installation of each wire harness component 130 and improving the assembly efficiency of the wire harness components 130.

[0036] It is understood that when there are multiple cell mounting portions 112, a cell row gap 1122 is formed between two adjacent cell mounting slots 1121 of each cell mounting portion 112 to ensure that a wire harness receiving channel is formed where the wire harness component 130 converges to the center. Since the multiple cell row gaps 1122 of each cell mounting portion 112 are connected one-to-one with the multiple cell row gaps 1122 of another adjacent cell mounting portion 112, the cell row gaps 1122 of each cell mounting portion 112 are connected one-to-one to ensure the connection of the wiring path. Each cell row gap 1122 and each embedded wire slot 1123 together form a preset wiring path to ensure that the overall wiring of the battery module 10A is neat and the structure is relatively compact.

[0037] In one embodiment, the cell row gap 1122 also forms a heat dissipation channel between adjacent cell mounting slots 1121. Since the surface temperature of the cell 30 in the cell mounting slot 1121 gradually increases during operation, heat is dissipated outwards in the form of thermal radiation. The cell row gap 1122 provides the necessary space for radiative heat exchange. The cell row gap 1122 maintains a certain distance between adjacent cells 30 to ensure effective heat dissipation during operation. When the wire harness 130 passes through the cell row gap 1122, the wire harness 130 is located in the side wall area of ​​the cell row gap 1122 and does not obstruct the original heat dissipation channel.

[0038] Please see Figure 2 In one embodiment, a wire bonding operation groove 113 is provided between two adjacent battery cell mounting slots 1121, and each wire bonding operation groove 113 is located at the end of the corresponding battery cell mounting slot 1121. An electrical connection piece 114 is also provided on the bracket housing 110. The electrical connection piece 114 is disposed in the wire bonding operation groove 113. The wire harness 130 adjacent to the wire bonding operation groove 113 is electrically connected to the electrical connection piece 114 to ensure that a wire bonding operation area is provided for the operator when performing the welding operation between the wire harness 130 and the electrical connection piece 114. This ensures that there is no interference between the welding head and the bracket housing 110 during the welding process, reduces operational obstacles, and allows the welding head to be smoothly extended to the welding point, facilitating assembly operations and improving assembly efficiency.

[0039] It is understood that, since one end of the electrical connecting piece 114 is located in the wire bonding operation groove 113, the wire harness 130 does not directly contact the electrode of the battery cell 30. Instead, the electrical connection is achieved through the electrical connecting piece 114 as an intermediate adapter. This ensures the stable and reliable electrical connection between the battery cell 30 and the wire harness 130, avoids the thermal impact of direct welding that could lead to performance degradation of the battery cell 30, and reduces welding difficulty and assembly cost, thereby improving assembly efficiency.

[0040] In one embodiment, there are multiple wire bonding operation grooves 113, and several of the wire bonding operation grooves 113 are opened between the end connections of two partially adjacent battery cell mounting grooves 1121 to ensure that a welding operation space is formed to facilitate the welding of the electrical connector 114 and the wire harness 130, thereby achieving neat wiring of the wire harness 130 of the integrated battery cell wire harness fixing device 10.

[0041] Please see Figure 2 In one embodiment, each of the electrical connectors 114 is abutted and connected to one end of a plurality of adjacent battery cells 30. One end of one of the wire harnesses 130 is connected to one of the electrical connectors 114 at the wire bonding operation groove 113. This allows multiple battery cells 30 to be connected in parallel through the same electrical connector 114, requiring only one wire harness 130 to connect to the electrical connector 114. This effectively reduces the number of wire harnesses 130, thereby avoiding messy wiring and mutual interference caused by a large number of wire harnesses 130, ensuring a simple overall structure, and also reducing the amount of welding work and assembly time.

[0042] In one embodiment, the electrical connector 114 is a bus.

[0043] Please see Figure 5 In one embodiment, each of the embedded wire-locking slots 1123 includes at least one first wire-locking protrusion 1124 and at least one second wire-locking protrusion 1125 disposed opposite to each other, with a wire-locking gap 1126 formed between the first wire-locking protrusion 1124 and the second wire-locking protrusion 1125; the corresponding wire harness 130 is snapped into the wire-locking gap 1126 and clamped and fixed by the first wire-locking protrusion 1124 and the second wire-locking protrusion 1125, so as to ensure that the wire harness 130 is firmly clamped by each first wire-locking protrusion 1124 and each second wire-locking protrusion. The wire harness 130 only needs to be pressed down from above the embedded wire-locking slot 1123 to snap the first wire-locking protrusion 1124 and the second wire-locking protrusion 1125 into the wire-locking gap 1126, thus completing the snap-fit ​​and fixing of the wire harness 130. This achieves one-step installation of alignment, embedding and clamping of the wire harness 130 without the need for binding with cable ties, which greatly improves assembly efficiency.

[0044] In one embodiment, the first wire-clamping protrusion 1124 and / or the second wire-clamping protrusion 1125 are elastic members. When the wire harness 130 is pressed into the wire-clamping gap 1126, the first wire-clamping protrusion 1124 and / or the second wire-clamping protrusion 1125 undergo elastic deformation. When the wire harness 130 reaches the predetermined position, the first wire-clamping protrusion 1124 and / or the second wire-clamping protrusion 1125 clamp the wire harness 130 in the wire-clamping gap 1126 by restoring its elastic deformation, and at the same time apply a continuous clamping force to the wire harness 130. This ensures reliable clamping and fixing of the wire harness 130 without the need for cable ties, and also facilitates subsequent inspection and maintenance.

[0045] In one embodiment, the width of the wire clamping gap 1126 is smaller than the outer diameter of the wire harness 130. When the wire harness 130 is inserted, the first wire clamping protrusion 1124 and / or the second wire clamping protrusion 1125 undergo elastic deformation and open outward. After the wire harness 130 enters, the protrusions elastically recover and clamp the wire harness 130, ensuring that the wire clamping gap 1126 can adapt to wire harnesses 130 of different wire diameters within a certain range, and ensuring that each wire harness 130 is reliably clamped and fixed.

[0046] In one embodiment, the first wire-clamping protrusion 1124 and the second wire-clamping protrusion 1125 are further provided with guide slopes. The guide slopes gradually narrow from the top of the first wire-clamping protrusion 1124 and the second wire-clamping protrusion 1125 toward the wire-clamping gap 1126, ensuring that the wire harness 130 can be snapped and fixed within the wire-clamping gap 1126 under the guidance of the guide slopes at the top of the first wire-clamping protrusion 1124 and the second wire-clamping protrusion 1125 simply by pressing down, without the need for cable ties, thus enabling the rapid installation of the wire harness 130 and improving assembly efficiency.

[0047] Please see Figure 6 In one embodiment, the bracket housing 110 is further provided with at least one sensor mounting post 115. Each sensor mounting post 115 is provided with a mounting positioning groove 1151 for mounting a sensor 1152. Each sensor 1152 is fixedly connected to the corresponding sensor mounting post 115. The sensor 1152 is connected to an adjacent wire harness 130, thereby ensuring that the sensor 1152 is reliably mounted on the sensor mounting post 115. The structure is relatively compact, and the sensor 1152 is embedded in the mounting positioning groove 1151, which can better avoid the wiring channel of the wire harness 130, and prevent the wire harness 130 from affecting the mounting position of the sensor 1152 when it is installed, thereby affecting the detection accuracy and signal acquisition accuracy of the sensor 1152.

[0048] In one embodiment, the sensor 1152 is a temperature sensor, ensuring that the sensor 1152 collects the temperature signal of the battery cell 30.

[0049] In one embodiment, the sensor 1152 is kept in contact with the outer peripheral surface of the battery cell 30 so that the sensor 1152 and the battery cell 30 make direct contact, ensuring the accuracy of the temperature signal acquisition of the battery cell 30. At the same time, by monitoring the surface temperature of the battery cell 30 in real time, a protection mechanism is triggered in time when the temperature of the battery cell 30 rises abnormally, preventing the battery cell 30 from overheating and ensuring the safety of the battery module 10A.

[0050] In one embodiment, the embedded wire slot 1123 is integrally formed with the bracket housing 110, thereby achieving a reliable connection between the embedded wire slot 1123 and the bracket housing 110. This ensures that the embedded wire slot 1123 will not loosen under long-term vibration conditions, thus avoiding displacement and detachment of the embedded wire slot 1123 caused by vibration conditions, and thereby ensuring the reliable installation of the wire harness 130.

[0051] In one embodiment, the mounting positioning groove 1151 is integrally formed with the bracket housing 110, thereby ensuring a reliable connection between the mounting positioning groove 1151 and the bracket housing 110, thus avoiding displacement of the mounting positioning groove 1151 caused by vibration and displacement of the sensor 1152 caused by detachment, thereby ensuring the accuracy and consistency of temperature signal acquisition.

[0052] Please see Figure 3 In one embodiment, a connector 50 is formed at one end of several of the wire harness components 130 that protrude from the wire harness outlet 120, so that the battery module 10A forms a uniform connection end, making the overall layout of the integrated cell wire harness fixing device 10 neat and the structure compact.

[0053] Please see Figure 7 In one embodiment, the wire harness receiving notch 121 includes a wide end 1211 located inside the periphery of the wire harness outlet 120 and a narrow end 1212 located outside the periphery of the wire harness outlet 120. The narrow end 1212 has a notch and is used for the wire harness component 130 to pass through and gather the wire harness. The wide end 1211 is used to accommodate a plurality of the wire harness components 130, ensuring that the plurality of wire harness components 130 can pass through the wide end 1211 to exit the integrated battery cell wire harness fixing device 10, preventing the wire harness components 130 from retracting, and realizing rapid assembly and reliable guidance of the wire harness components 130.

[0054] In one embodiment, the aperture of the narrow end 1212 is adapted to the outer diameter of the wire harness 130 to ensure circumferential constraint on the wire harness after it has been passed through, preventing the wire harness from retracting.

[0055] Please see Figure 8 In one embodiment, the wire harness outlet 120 has an embedded wire protection cavity 122 formed on the side facing the cell mounting portion 112. The embedded wire protection cavity 122 is configured to avoid misalignment with at least a portion of the wire harness 130. The wire protection cavity is a recessed groove structure to ensure that it provides a buffer for the bent section of the wire harness 130, thereby effectively preventing wear of the wire harness 130 due to assembly pulling, module stacking or transportation vibration.

[0056] In one embodiment, the wire harness outlet 120 is also provided with a visual anti-mistake viewing hole 123. The visual anti-mistake viewing hole 123 is positioned opposite to the embedded wire protection cavity 122, so that the operator can directly observe the housing status of the wire harness component 130 inside the embedded wire protection cavity 122 through the visual anti-mistake viewing hole 123. Without disassembling the bracket housing 110, the operator can directly confirm whether the wire harness component 130 has been properly threaded and secured through the visual anti-mistake viewing hole 123, thereby ensuring the accurate and reliable installation of the wire harness component 130.

[0057] Please see Figure 9 In one embodiment, a wedge-shaped guide surface 124 is provided on the groove wall of the wire harness receiving notch 121. The wedge-shaped guide surface 124 is located on the side of the wire harness output portion 120 facing the cell mounting portion 112. The wedge-shaped guide surface 124 extends smoothly and obliquely from the wire inlet direction to the wire outlet direction of the wire harness receiving notch 121, thereby guiding the wire harness component 130 to extend smoothly along the wedge-shaped guide surface 124 to the wire harness receiving notch 121, so as to reduce the bending angle of the wire harness component 130 at the bend and avoid damage to the wire harness component 130 due to excessive bending angle.

[0058] Please see Figure 9 In one embodiment, a clamping member 1213 is further provided on the groove wall of the narrow end 1212 of the wire harness receiving notch 121. The clamping block protrudes from the opposite two sides of the groove wall of the narrow end 1212. The friction-increasing clamping block abuts against the outer peripheral surface of the wire harness 130 passing through the narrow end 1212 to increase the contact area and friction between the wire harness 130 and the groove wall of the narrow end 1212, thereby better clamping and fixing the wire harness 130 in the narrow end 1212.

[0059] In one embodiment, the clamping member 1213 is disposed on the groove wall of the narrow end 1212, the clamping member 1213 protrudes into the narrow end 1212, and the clamping direction of the clamping member 1213 is perpendicular to the insertion direction of the wire harness 130, so as to ensure that the clamping member 1213 can better clamp and fix the wire harness 130 inserted into the narrow end 1212.

[0060] In one embodiment, an elastic protrusion 1214 is provided at the contact point between the clamping member 1213 and the outer peripheral surface of the wire harness member 130. When the wire harness member 130 is inserted into the narrow end 1212, the outer peripheral surface of the wire harness member 130 is in contact with the contact surfaces of the elastic protrusions 1214 on both sides. The elastic protrusions 1214 undergo slight elastic deformation, applying a radial clamping force to the wire harness member 130, thereby clamping and fixing the wire harness member 130 in the narrow end 1212.

[0061] In one embodiment, the elastic bump 1214 has an anti-slip texture on the side facing the wire harness 130. The anti-slip texture is at least one of raised dots, horizontal lines, diagonal lines, or grid patterns, to ensure that the friction between the elastic bump 1214 and the outer peripheral surface of the wire harness 130 is increased, so that the wire harness 130 is better clamped and fixed at the narrow end 1212.

[0062] In one embodiment, the two elastic protrusions 1214 are respectively disposed on the opposite side groove walls of the narrow end 1212. The two elastic protrusions 1214 are disposed opposite each other and symmetrically distributed about the center line of the narrow end 1212. The two elastic protrusions 1214 protrude from the corresponding groove walls at equal heights.

[0063] In one embodiment, a heating film is also provided on the battery cell mounting part 112. The heating film abuts against the outer peripheral surface of the battery cell 30. One end of the heating film is provided with a heating film connector 116. The heating film connector 116 is connected to the wire harness 130 and is used to preheat the battery cell 30 in a low-temperature environment.

[0064] In one embodiment, the wiring harness 130 connected to the heating film connector 116 extends to the wiring harness receiving notch 121.

[0065] Please see Figure 3In one embodiment, the cell mounting portion 112 includes a first clamping post 1127 and a second clamping post 1128 disposed opposite to each other. The first clamping post 1127 and the second clamping post 1128 have a mounting hole at one end. A cell mounting groove 1121 is formed between each of the first clamping post 1127 and each of the second clamping posts 1128. The second clamping post 1128 and the first clamping post 1127 have a mounting post at one end. The mounting post passes through the mounting hole and engages with the mounting hole to ensure that the first clamping post 1127 and the second clamping post 1128 are fixedly connected.

[0066] Please see Figure 2 In one embodiment, the cell mounting part 112 is provided with a mounting sleeve hole, and the bracket housing 110 is also provided with a mounting protrusion 117. The mounting protrusion 117 passes through the mounting sleeve holes of two adjacent sets of cell mounting parts 112 to realize the connection and fixation of the two adjacent sets of cell mounting parts 112.

[0067] Please see Figure 2 In one embodiment, the electrical connector 114 is further provided with a snap-fit ​​fixing hole 1141, which is sleeved on the corresponding mounting protrusion 117. The mounting protrusion 117 snaps and fixes the electrical connector 114, ensuring that the relative position between the electrical connector 114 and the plurality of battery cells 30 is accurate, and realizing the reliable assembly of the busbar.

[0068] Please see Figure 1 In one embodiment, the bracket housing 110 is further provided with a bracket mounting portion 118, which is respectively disposed at both ends of the bracket housing 110 in the length direction, for forming a fixed connection with the battery pack housing 40, so as to install and fix the bracket housing 110 inside the battery pack housing 40.

[0069] In one embodiment, each of the bracket mounting portions 118 is provided with a plurality of bracket mounting holes. Fasteners pass through the bracket mounting holes to fix the bracket housing 110 to the battery pack housing 40. The bracket housing 110 and the battery pack housing 40 are fixedly connected by a plurality of fasteners to ensure that the impact of vibration on the battery cells 30 and wiring harnesses 130 in the bracket housing 110 is reduced under the vibration conditions generated by vehicle driving.

[0070] In one embodiment, a fastening assembly 119 is also formed on the bracket housing 110. The fastening assembly 119 includes a plurality of fastening members, each of which is arranged sequentially on the bracket housing 110 along the length direction of the embedded wire-locking groove 1123. It is used to fix the wire harness 130 or the wire harness 130 at multiple points in the embedded wire-locking groove 1123. The plurality of fastening members are arranged sequentially along the length direction of the embedded wire-locking groove 1123, forming multiple fixing points on the entire extension path of the wire harness 130. This allows the wire harness 130 to be constrained within the receiving channel, while being further locked by the fastening members at each fixing point, thus achieving better fixation of the wire harness 130. The wire harness is reliably constrained at any position, ensuring that the wiring of the wire harness assembly is neat.

[0071] This disclosure also provides a battery module 10A, including an electronic board 20, a plurality of battery cells 30, and a battery pack housing 40. Further, the battery module 10A also includes an integrated battery cell wiring harness fixing device 10 as described in any of the above embodiments; wherein the integrated battery cell wiring harness fixing device 10 is disposed within the battery pack housing 40 and is fixedly connected to one end of the battery pack housing 40 via a bracket mounting portion 118; each of the battery cells 30 is disposed within a corresponding battery cell mounting slot 1121; the battery pack housing 40 is provided with an electronic board 20 mounting position, the electronic board 20 is disposed at the electronic board 20 mounting position, and the electronic board 20 mounting position is located beside one end of an embedded wire-holding groove 1123; the wiring harness 130 extends along the embedded wire-holding groove 1123. The wire harness extends through the wire harness receiving notch 121 and exits the bracket housing 110. It then connects to the mating connector 50 on the electronic board 20 via the connector 50 located at the end of the wire harness component 130. This achieves electrical connection. Thus, the integrated cell wire harness fixing device 10 forms a neat wire harness channel. During assembly, the wire harness component 130 is installed along the preset cell row gap 1122 and the embedded wire clip groove 1123. The preset routing path of each wire harness component 130 is planned to ensure that the overall wiring of the battery module 10A is neat and tidy. It eliminates the need for cable ties to bundle the wires, thereby enabling the rapid installation of the battery module 10A and ensuring convenient installation and overall safety and reliability.

[0072] In one embodiment, the battery cell 30 is a cylindrical battery cell 30.

[0073] In one embodiment, a cylindrical mounting cavity is formed on the battery cell 30 mounting base.

[0074] In one embodiment, a connector 50 is provided at the end of the wire harness 130 that leads out of the bracket housing 110, so that the connector 50 is arranged at the center of the integrated cell wire harness fixing device 10, thereby ensuring that the connector 50 is centrally arranged so that each wire harness 130 can converge to the output port of the battery module 10A with a shorter path, thereby reducing the amount of wire used in the wire harness 130, simplifying the wiring complexity, improving the accuracy of communication acquisition, and improving the space utilization of the battery module 10A.

[0075] In one embodiment, the position where the wire harness 130 passes through the wire harness guide junction hole and exits the bracket housing 110 is located in the middle region of the bracket housing 110. After each wire harness 130 is led out from the electrode of the corresponding cell 30, it converges radially at the connector 50 with the connector 50 as the center, so that the length of each branch wire harness is the shortest and tends to be consistent, which is beneficial to reduce the amount of wire used, reduce voltage drop difference, and improve signal acquisition accuracy.

[0076] In one embodiment, the connector 50 is detachably mounted to the end of the wiring harness 130 to make maintenance of the battery module 10A quick and easy.

[0077] In one embodiment, a buffer 60 is provided at the contact point between the integrated cell harness fixing device 10 and the battery pack housing 40 to ensure that the buffer 60 protects the integrated cell harness fixing device 10 under vibration conditions, thereby ensuring the overall safety and reliability of the battery module 10A.

[0078] Compared with the prior art, this disclosure has at least the following advantages: 1) Since the bracket housing 110 is provided with at least one cell mounting part 112, the cell mounting part 112 has a plurality of spaced cell mounting slots 1121, each of the cell mounting slots 1121 is used to mount a cell 30; a cell row gap 1122 is formed between each two adjacent cell mounting slots 1121, and each cell row gap 1122 is connected to the embedded wire slot 1123 so that each cell row gap 1122 forms a wiring path, ensuring that the wire harness 130 is radially limited in the cell row gap 1122. The cell row gap 1122 serves as a branch wiring channel for the wire harness 130, allowing the wire harness 130 to be directly inserted into the cell row gap 1122 and extend to the wire harness outlet part 120, ensuring that the wiring layout of the wire harness 130 is neat and the structure is compact. Furthermore, since the bracket housing 110 is also provided with an embedded wire-locking groove 1123, the extension direction of the embedded wire-locking groove 1123 is parallel to the arrangement direction of the plurality of battery cell mounting slots 1121, and the embedded wire-locking groove 1123 is set adjacent to the end of each battery cell mounting slot 1121, it is ensured that during assembly, the wire harness 130 is locked and installed along the preset battery cell row gap 1122 and the embedded wire-locking groove 1123, which forms a good constraint protection for the wire harness 130 and better avoids the risk of entanglement and friction between the wire harnesses 130. Thus, a pre-set wiring path for the wire harness 130 with neat wiring is formed on the bracket housing 110, ensuring the accurate and reliable installation of each wire harness 130. In this way, the one-step installation of the alignment, embedding and locking of the wire harness 130 is realized without the need for binding operation, which greatly improves the assembly efficiency of the wire harness 130.

[0079] 2) Since the wire harness outlet 120 is connected to the bracket housing 110 and the wire harness outlet 120 is located at one end of the embedded wire slot 1123, it forms a gathering channel for the wire harness components 130. This allows each wire harness component 130 to converge along the embedded wire slot 1123 to the wire harness outlet 120, ensuring a short convergence path for the wire harness components 130. The embedded wire slot 1123 in the bracket housing 110 enables the installation and securing of the wire harness components 130, preventing cross-entanglement of the wire harnesses during convergence to the wire harness outlet 120. This avoids signal interference and friction risks caused by disordered interweaving of the wire harness components 130, reducing safety hazards. At the same time, there is no need to use cable ties for binding and fixing, making the overall layout of the wire harness components 130 clearer and more standardized, facilitating later inspection and maintenance. Only the wire harness component 130 to be repaired needs to be pulled out from the corresponding cell array gap 1122 for maintenance, without the need for destructive disassembly.

[0080] 3) Since the periphery of the wire harness outlet 120 is provided with a wire harness receiving notch 121 that communicates with the embedded wire slot 1123, the wire harness receiving notch 121 is used to pass through the ends of multiple wire harness components 130, so as to ensure that after the wire harness component 130 is led out through the embedded wire slot 1123, it can be directly passed through the wire harness receiving notch 121. The operator can directly insert the wire harness component 130 from the opening of the wire harness receiving notch 121 without passing it through the through hole, which improves the assembly efficiency of the wire harness component 130. In addition, at least one of the wire harness components 130 is interference-fitted into the wire harness receiving notch 121, which effectively prevents the wire harness component 130 from shifting or moving during subsequent assembly.

[0081] 4) Since some of the wire harness components 130 are sequentially arranged in the adjacent cell busbar gaps 1122 and the embedded wire clamping grooves 1123 and extend to the wire harness receiving opening 121, and other wire harness components 130 are arranged in the embedded wire clamping grooves 1123 and extend to the wire harness receiving opening 121, it is ensured that each cell busbar gap 1122 and the embedded wire clamping groove 1123 clamps and installs each wire harness component 130 along the wiring path of each wire harness component 130, ensuring that the wire harness component 130 is well constrained and protected. A neat wire harness channel is formed on the bracket housing 110, and it is further ensured that each wire harness component 130 converges to the wire harness receiving opening 121 with a shorter path. This effectively shortens the length of each wire harness component 130, thereby reducing the amount of wire used, reducing the material cost of the wire harness component 130, and greatly improving the assembly efficiency of the wire harness component 130.

[0082] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
