Description

Technical Field

[0001] This utility model relates to the field of battery cell clamping strip technology, and in particular to a battery cell clamping strip for battery modules. Background Technology

[0002] Cell clamping strips are components used to fix and press battery cells together. They play an important supporting and limiting role in battery packs or battery modules. Specifically, their functions are as follows: First, they restrict the movement of cells within the battery pack, ensuring that the cells maintain a stable position during use and preventing problems such as cell displacement and short circuits caused by vibration and collisions. Second, they suppress the expansion of cells during charging and discharging. Since cells undergo volume changes during charging and discharging, the clamping strips can apply a certain amount of pressure to limit the degree of expansion, preventing compression and deformation between cells and extending their service life. Finally, they increase the overall rigidity and strength of the battery pack or module, enabling the battery system to better withstand external impacts and pressures and protecting the cells from damage.

[0003] In order to bind the battery cell wire harness, holes are usually made on the battery cell pressure bar. The holes can be used to pass the wire harness through. Then, the wire harness is usually bound manually using strip and binding materials to organize and fix the wire harness on the surface or in the space designed inside the battery cell pressure bar. Although this traditional binding method can meet the needs of wire harness organization, it still requires a lot of manual time for binding, which is inefficient, increases labor costs, and is difficult to adapt to the needs of large-scale production.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cell clamping strip for a battery module, comprising a clamping strip frame with a rectangular structure, a base plate that is in close contact with the battery module at the lower end of the clamping strip frame, the clamping strip frame and the base plate forming a wire harness storage chamber, the clamping strip frame having an inlet port that communicates with the wire harness storage chamber, and a wire management window at the upper end of the clamping strip frame, after the wire harness enters the wire harness storage chamber from the inlet port, the operator manages it through the wire management window;

[0007] The substrate is provided with a wire harness pressure plate, which can be deformed to press the wire harness in place.

[0008] As a further embodiment of this utility model, the pressure strip frame and the base plate are fixedly connected by welding.

[0009] As a further embodiment of this utility model: a wire harness pressure plate is formed on the substrate by punching, and a groove is formed on the substrate;

[0010] The wire harness pressure plate includes an inclined portion and a wire pressing portion. One end of the inclined portion is connected to the base plate, and the other end is connected to the wire pressing portion. An opening is formed between the end of the wire pressing portion away from the inclined portion and the base plate. The wire harness enters the lower end of the wire pressing portion through the opening.

[0011] As a further embodiment of this utility model: the end of the pressure line facing the opening forms an upward arc shape.

[0012] As a further embodiment of this utility model: multiple wire harness pressure plates are provided and are evenly arranged in an array on the substrate.

[0013] As a further embodiment of this utility model: the substrate is provided with a plurality of positioning grooves, and the positioning grooves and the wire harness pressure plate are alternately distributed.

[0014] As a further embodiment of this utility model: the two ends of the pressure strip frame are provided with fixing ear plates, and the fixing ear plates are provided with fixing holes.

[0015] As a further embodiment of this utility model: the pressure strip frame is also provided with a connecting part located between the wire harness storage chamber and the wire inlet, and the connecting part is provided with a riveting nut by a riveting process.

[0016] As a further embodiment of this utility model: a riveting stud is provided on the side of the substrate away from the connecting part by a riveting process.

[0017] Compared with the existing technology, the beneficial effects of this technical solution are as follows: When organizing the wire harness of the battery cell, the wire harness is organized and stored in the cavity through the wire inlet on the pressure bar frame, and then organized under the wire harness pressure plate through the wire management window at the upper end of the pressure bar frame. The wire harness pressure plate is used to press the wire harness down, thereby completing the organization of the battery cell wire harness. It is simple and fast, and the wire harness can be neatly organized without spending too much time, thereby improving efficiency, reducing costs, and meeting production needs.

[0018] In this process, after the wire harness is pulled close to the wire harness storage chamber, the wire harness pressure plate can be deformed to a certain extent by manual means, so that the wire harness can be arranged under the wire harness pressure plate. Then, the wire harness pressure plate is elastically restored to press the wire harness down.

[0019] Furthermore, the base plate can be fixedly connected to the pressure strip frame through welding, forming a closed structure. When applied to a battery module, it can be fixed to the outer frame of the battery module, which can greatly improve the overall strength of the cell pressure strip, thereby improving its supporting and limiting effect on the battery module. In addition, the increased strength will also enhance the effect of suppressing the expansion of the cell during charging and discharging, thus better protecting the cell.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-2A battery module cell clamping strip includes a rectangular clamping frame 1, a base plate 2 that is in close contact with the battery module at the lower end of the clamping frame 1, and the clamping frame 1 and the base plate 2 enclose a wire harness storage chamber 3. The clamping frame 1 has an inlet 4 that communicates with the wire harness storage chamber 3, and a wire management window 5 is also provided at the upper end of the clamping frame 1. After the wire harness enters the wire harness storage chamber 3 from the inlet 4, the operator can organize it through the wire management window 5.

[0028] A wire harness pressure plate 6 is provided on the film 2. The wire harness pressure plate 6 can be deformed to press the wire harness down.

[0029] Specifically, when installing the wire core clamping strip, the interconnected clamping strip frame 1 and base plate 2 are placed on the battery module and fixed to the battery module frame. When organizing the wire harness of the battery cell, the wire harness is organized and stored in the wire harness storage chamber 3 through the wire inlet on the clamping strip frame 1, and the wire harness is organized under the wire harness clamping plate 6 through the wire management window 5 at the upper end of the clamping strip frame 1. The wire harness clamping plate 6 is used to press the wire harness, thereby completing the organization of the battery cell wire harness. It is simple and fast, and the wire harness can be neatly stored without spending too much time, thereby improving efficiency, reducing costs, and meeting production needs.

[0030] Furthermore, after the wire harness is pulled close to the wire harness storage chamber 3, the wire harness pressure plate 6 can be deformed to a certain extent by human power, so as to facilitate the wire harness to be arranged under the wire harness pressure plate 6. Then the wire harness pressure plate 6 is elastically restored to press the wire harness down.

[0031] The battery cell pressure strip consists of a pressure strip frame 1 and a base plate 2. During installation, the base plate 2 contacts the battery cell, so that after the wire harness is organized into the wire harness storage chamber 3, it can be isolated from the battery cell, thereby reducing the impact of battery cell heating on the wire harness and improving the safety and stability of the battery module during use.

[0032] More preferably, the base plate 2 can be fixedly connected to the pressure strip frame 1 by welding process, so that the whole is enclosed into a closed structure. When applied to the battery module, it can be fixedly connected to the outer frame of the battery module, which can greatly improve the overall strength of the cell pressure strip, thereby improving its supporting and limiting effect on the battery module. In addition, the increased strength will also enhance the effect of suppressing the expansion of the cell during charging and discharging, thus better protecting the cell.

[0033] In some embodiments, a wire harness pressure plate 6 is formed on the substrate 2 by punching, and a groove is formed on the substrate 2;

[0034] The wire harness pressure plate 6 includes an inclined portion 61 and a wire pressing portion 62. One end of the inclined portion 61 is connected to the substrate 2, and the other end is connected to the wire pressing portion 62. An opening 7 is formed between the end of the wire pressing portion 62 away from the inclined portion 61 and the substrate 2. The wire harness enters the lower end of the wire pressing portion 62 through the opening 7.

[0035] Specifically, the wire harness pressure plate 6 formed by punching is integrated with the substrate 2, thereby ensuring that the strength meets the usage requirements and preventing the wire harness pressure plate 6 from being damaged or detached from the substrate 2.

[0036] When organizing the wire harness, the worker can apply a certain pressure to the wire pressing part 62 of the wire harness pressing plate 6 to deform the wire pressing part 62, that is, deform the connection between the inclined part 61 and the base plate 2, thereby increasing the space of the opening 7. At this time, the wire harness is inserted into the lower end of the wire pressing part 62 through the opening 7, and then the wire pressing part 62 is released to restore its original shape and press the wire harness down, so as to fix the wire harness.

[0037] In some embodiments, the pressure line portion 62 forms an upward arc-shaped portion 63 at one end facing the opening portion 7.

[0038] Specifically, the design of the arc-shaped part 63 can increase the space size of the opening 7, thereby making it easier to organize the wire harness below the wire pressing part 62.

[0039] In some embodiments, multiple wire harness pressure plates 6 are provided and are evenly arranged in an array on the substrate 2, thereby improving the fixing effect of the wire harness.

[0040] In some embodiments, a second wire harness pressure plate is provided on the inner wall of the pressure strip frame 1; its structure is the same as that of the wire harness pressure plate 6, so that more wire harnesses can be pressed and fixed, or different wire harnesses can be separated and pressed and fixed, which will not be described in detail here.

[0041] In some embodiments, the substrate 2 has a plurality of positioning grooves 8, and the positioning grooves 8 and the wire harness pressure plate 6 are alternately distributed.

[0042] Specifically, the positioning groove 8 allows for positioning and insertion with the positioning post on the battery cell during the installation of the battery cell pressure strip, ensuring accurate installation of the battery cell pressure strip. The alternating distribution of the positioning groove 8 and the wire harness pressure plate 6 avoids affecting the use of the wire harness pressure plate 6.

[0043] In some embodiments, the two ends of the pressure strip frame 1 are provided with fixing ear plates 9, and the fixing ear plates 9 are provided with fixing holes 91.

[0044] Specifically, the ear plate 9 and the fixing hole 91 on it can be fixed to the outer frame of the battery module by bolts, so that the cell pressure strip and the outer frame can be combined to form an overall frame to protect the battery module.

[0045] In some embodiments, the pressure strip frame 1 is further provided with a connecting part 10 located between the wire harness storage chamber 3 and the wire inlet 4, and a riveting nut 11 is provided on the connecting part 10 by a riveting process.

[0046] Specifically, the press-fit nut 11 provides internal threads for the components that need to be connected, and is used in conjunction with bolts or studs to achieve a fastening connection between the components. For example, when it is necessary to install some electronic components, sensors or other small parts onto the battery cell clamping strip, bolts can be passed through the holes on these components and then tightened with the press-fit nut 11 to securely fix the components to the clamping strip.

[0047] In some embodiments, a press-fit stud 12 is provided on the side of the substrate 2 away from the connecting portion 10 by a press-fit process.

[0048] Specifically, the press-fit stud 12 provides a reliable threaded connection point, which, when engaged with a nut or other threaded parts, allows the cell clamping strip to be connected to the battery pack's casing, bracket, heat sink, and other components. This connection method facilitates installation and disassembly, enabling convenient operation during battery pack production, assembly, and subsequent maintenance.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
