Description

Technical Field

[0001] This specification relates to the field of electrical systems technology, and in particular to a battery device and a cable tie fixing device. Background Technology

[0002] In the field of electrical assembly, cable bundling is a core process for achieving neat cable arrangement, ensuring stable electrical connections, and improving product assembly precision. For example, in the enclosure of a battery device, cables extending inside the enclosure can be threaded through cable ties and secured with them, thus preventing cable breakage or partial short circuits and improving cable safety and reliability. Specifically, after bundling cables with cable ties, they generally need to be secured using cable tie fixing devices to ensure cable stability.

[0003] This specification provides a battery device, an electrical appliance, and a cable tie fixing device through some embodiments. By improving the structure of the cable tie fixing device, the safety of cable use is enhanced and the space utilization of the battery device enclosure is optimized. Utility Model Content

[0004] Based on this, this application provides a battery device, electrical equipment, and cable tie fixing device, which improves the spatial adaptability of the cable tie fixing device, making it applicable to different cable assembly areas. While achieving stable cable fixing and improving cable safety, it reduces the risk of interference between the cable and the cable tie fixing device and other components, and optimizes the space utilization of the battery device housing.

[0005] In a first aspect, this application provides a battery device comprising: a plurality of battery cells; a housing having a receiving cavity in which the plurality of battery cells are disposed; and a cable, a cable tie, and a cable tie fixing device disposed in the receiving cavity; the cable is bundled by the cable tie; the cable tie fixing device has a first direction and a second direction perpendicular to each other, and the cable tie fixing device includes: a fixing part extending along the first direction and fixed to the housing; and a cable tie mounting part connected to the cable tie; wherein the fixing part and the cable tie mounting part are arranged along the second direction. By designing the fixing part to extend along the first direction and the fixing part and the cable tie mounting part to be arranged along the second direction, the fixing position of the fixing part can be eccentrically set relative to the cable, making the fixing position of the fixing part more flexible and improving the adaptability of the cable tie fixing device to assembly areas of different shapes and sizes of different cables. At the same time, the design of the fixing position of the fixing part being eccentrically set relative to the cable also makes the axial dimension of the cable tie fixing device smaller, which is suitable for compact battery devices with small internal space and avoids excessive force on the cable by the cable tie, which could damage the cable.

[0006] In some embodiments, the cable tie fixing device further includes a connecting portion that connects the fixing portion and the cable tie mounting portion. The cable tie mounting portion is disposed at at least one end of the connecting portion located in the second direction, and the fixing portion and the cable tie mounting portion are spaced apart along the second direction. The design of the connecting portion enables the fixing portion and the cable tie mounting portion to be arranged along the second direction. The spaced arrangement of the fixing portion and the cable tie mounting portion along the second direction increases the degree of eccentricity of the fixing position relative to the cable, thereby further improving the flexibility of the fixing position and enhancing the adaptability of the cable tie fixing device to assembly areas of different shapes and sizes of different cables.

[0007] In some embodiments, the cable tie mounting portion has a first reinforcing portion protruding from the connecting portion along a first direction. The provision of the first reinforcing portion can enhance the structural strength of the cable tie mounting portion, improve its stability and safety, and reduce the risk of damage to the cable tie mounting portion. Simultaneously, the design of the first reinforcing portion can also increase the size or area of ​​the cable tie mounting portion in the first direction, thereby providing a larger contact surface for the bundled cables and improving cable stability.

[0008] In some embodiments, the first reinforcing part and the fixing part are located on the same side of the connecting part along the first direction, so as to effectively reduce the overall size of the cable tie fixing device along the first direction, avoid the cable tie fixing device from squeezing the assembly area of ​​other components when fixing the cable, make the cable tie fixing device suitable for battery devices with small internal space, and avoid the cable tie from applying too much force to the cable, which would cause the cable to be damaged.

[0009] In some embodiments, the cable tie fixing device further has a third direction perpendicular to the first and second directions, and the cable tie mounting portion further has a second reinforcing portion protruding from the connecting portion along the third direction. The design of the second reinforcing portion can further enhance the structural strength of the cable tie mounting portion and improve the operational stability of the cable tie fixing device. Simultaneously, the second reinforcing portion can also increase the size or area of ​​the cable tie mounting portion in the third direction, thereby providing a larger contact surface for the bundled cables and improving cable stability.

[0010] In some embodiments, the cable tie mounting part includes a main body connected to the connecting part. The main body has a groove, and a mounting post is provided in the groove. The two ends of the mounting post are fixed to two opposite side walls of the groove. An clearance gap is formed between the mounting post and the bottom wall of the groove. The cable tie passes through the clearance gap, and the mounting post is located in the loop formed by the cable tie, thereby realizing the installation of the cable tie.

[0011] In some embodiments, the cable tie fixing device further has a third direction perpendicular to the first and second directions, with the mounting post extending along this third direction. This allows the fixing position of the fixing part to be offset relative to the cable, making the fixing position more flexible and improving the adaptability of the cable tie fixing device to assembly areas of different shapes and sizes of different cables. Simultaneously, the design of the fixing position being offset relative to the cable also results in a smaller axial dimension of the cable tie fixing device, making it suitable for compact battery devices with limited internal space and preventing excessive force applied to the cable by the cable tie, which could damage the cable.

[0012] In some embodiments, the ends of the cable tie mounting portion and the connecting portion are rotatably connected about a second direction. With the cable (cable tie) in the same position, the connecting portion and the fixing portion can rotate about the second direction to adjust the orientation of the fixing portion, thereby further increasing the installation flexibility of the cable tie fixing device. This allows users to flexibly adjust the cable tie fixing device based on the internal spatial structure and component layout of the enclosure, avoiding interference between the cable tie fixing device and other components.

[0013] In some embodiments, the cable tie mounting portion and / or the end portion are provided with a first locking structure, which locks or unlocks the rotatable connection between the cable tie mounting portion and the end portion.

[0014] In some embodiments, the fixing part and the connecting part are rotatably connected about a first direction. With the fixing part in a fixed position, the connecting part, the cable tie mounting part, and the cable tie can rotate about the first direction to adjust the extension direction of the cable. Even when the cable tie fixing device secures the cable, the cable still has room for bending and adjustment. During other cable tie fixing devices, cable assembly, and subsequent maintenance, the cable arrangement and extension direction can be flexibly changed, preventing damage to the core wires due to forced bending and improving the ease of cable assembly and disassembly and maintainability.

[0015] In some embodiments, the fixing part and / or the connecting part are provided with a second locking structure, which locks or unlocks the rotatable connection between the fixing part and the connecting part.

[0016] In some embodiments, the cable tie includes a cable tie head and a cable body. One end of the cable body is fixedly connected to the cable tie head, and the other end of the cable body passes through the cable tie mounting portion of the cable tie fixing device and extends into the cable tie head to form a loop to fix the cable.

[0017] Secondly, this application provides an electrical device that includes a battery device as described in any of the preceding claims, the battery device serving as a power source for the electrical device and / or an energy storage unit for the electrical device. Where the battery device can be designed to be lightweight and compact, the size of the electrical device can also be smaller, and it can also be designed to be lightweight and compact.

[0018] Thirdly, this application provides a cable tie fixing device, including: a fixing part extending along a first direction; and a cable tie mounting part configured to connect with a cable tie; wherein the fixing part and the cable tie mounting part are spaced apart along a second direction; the first direction is perpendicular to the second direction. By designing the fixing part to extend along the first direction and the fixing part and the cable tie mounting part to be arranged along the second direction, the fixing position of the fixing part can be set off-center relative to the cable, making the fixing position of the fixing part more flexible and improving the adaptability of the cable tie fixing device to assembly areas of different shapes and sizes of different cables.

[0022] The accompanying drawings used in the description of the embodiments will be briefly introduced below. The drawings do not represent all embodiments.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0024] In the description of the embodiments of this application, technical terms such as "first," "second," and "third" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, and "each" means each of the multiple, unless otherwise explicitly defined.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In the field of electrical assembly, cable bundling is a core process for achieving neat cable arrangement, ensuring stable electrical connections, and improving product assembly precision. For example, in the enclosure of a battery device, cables extending inside the enclosure can be threaded through cable ties and secured with them, thus preventing cable breakage or partial short circuits and improving cable safety and reliability. Specifically, after bundling cables with cable ties, they generally need to be secured using cable tie fixing devices to ensure cable stability.

[0029] In some cable bundling processes, the fixing part of the cable tie fixing device is arranged along the radial direction of the cable being bundled, with its axis passing through the center of the cable and coaxially distributed with the bundled cable. For example, the fixing part is located directly below the cable being bundled. This results in the cable tie fixing device having high requirements for the circumferential assembly area of ​​the cable, poor spatial adaptability, and making the cable and cable tie fixing device prone to interference with surrounding components.

[0030] Figure 1 This is a structural schematic diagram of a cable tie fixing device according to one or more embodiments. Figure 1 As shown, the cable tie fixing device 100 includes a fixing part 110 and a cable tie mounting part 120 that are connected to each other. The cable tie 140 forms a loop to bundle the cable 150, and the cable tie mounting part 120 fixes the cable tie 140.

[0031] like Figure 1 As shown, the extension direction of cable 150 is perpendicular to the plane of the paper. In the radial direction perpendicular to the extension direction of cable 150, the axis L1 of fixing part 110 is relatively close to the center O of cable 150. In some other designs, the axis L1 of fixing part 110 even passes through the center O of cable 150, that is, the axis L1 of fixing part 110 is coaxial with the center O of cable 150. For example, fixing part 110 is directly below cable 150. This results in poor spatial adaptability of cable tie fixing device 100, and the fixing position of cable tie fixing device 100 relative to cable is relatively limited. Cable tie fixing device 100 and cable are prone to interference with other components. To avoid interference problems, cable tie fixing device 100 and cable need more space with other components, which leads to a larger overall size of battery device and lower space utilization within the battery device casing.

[0032] Furthermore, the coaxial (or near-coaxial) design of the cable tie fixing device 100 requires a large space to be reserved in the axial direction of the fixing part 110 of the cable tie fixing device 100 to accommodate the bundled wire harnesses or cables. When the structural components in the battery pack housing (such as the cover, beam, or control box, etc.) cannot reserve more space in the axial direction of the fixing part 110 of the cable tie fixing device 100 due to their own functional limitations or compact design requirements, it is easy for the bundled cables 150 to be squeezed and rubbed against each other, accelerating cable aging, and in severe cases, even cable breakage or partial short circuits may occur.

[0033] To address this issue, some embodiments of this specification provide a battery device, an electrical appliance, and a cable tie fixing device. The battery device includes a housing with a receiving cavity. Multiple battery cells, cables, cable ties, and a cable tie fixing device are disposed within the receiving cavity, with the cables bundled by the cable ties. The cable tie fixing device has a first direction and a second direction perpendicular to each other. The cable tie fixing device includes a fixing part extending along the first direction and a cable tie mounting part connected to the cable tie. The fixing part and the cable tie mounting part are arranged along the second direction, thereby offsetting the axis of the fixing part from the center of the bundled cables (i.e., the fixing position of the fixing part can be eccentrically positioned relative to the cables). This allows for greater flexibility in the fixing position, improving the adaptability of the cable tie fixing device to assembly areas with different shapes and sizes of cables. While achieving stable cable fixing, it reduces the risk of interference between the cables, the cable tie fixing device, and other components. Furthermore, the eccentric positioning of the fixing part relative to the cables results in a smaller axial dimension of the cable tie fixing device, making it suitable for compact battery devices with limited internal space and preventing excessive force from the cable tie on the cables, which could lead to cable damage.

[0034] The technical solutions described in this application are applicable to various battery-powered devices, such as mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, automobiles, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys; automobiles can be gasoline-powered cars, natural gas-powered cars, or new energy vehicles, and new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles; spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0035] Figure 2 This is a schematic diagram of the structure of a battery device according to one or more embodiments.

[0036] Please refer to Figure 2The battery device 200 includes a housing 210 with a receiving cavity containing multiple battery cells 220. The receiving cavity also contains cables, cable ties, and a cable tie fixing device (not shown in the figure). The cables are bundled with cable ties, which are installed on the cable tie fixing device, which is fixedly positioned within the receiving cavity to secure the cables. It should be noted that cable ties can be used to bundle single cables or multiple cables forming a bundle. For ease of description, the following explanation uses the example of cable ties bundling cables.

[0037] The box 210 can be of various shapes, such as a cylinder or a cuboid. The box 210 may further include a lid 211 and a lower box 212, with the lid 211 covering the opening of the lower box 212, and the two together defining the receiving cavity 213.

[0038] Multiple battery cells 220 can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple battery cells 220 are connected in both series and parallel. Multiple battery cells 220 can be directly connected in series, parallel, or in a mixed manner, and then the whole assembly of multiple battery cells 220 is housed in the housing 210.

[0039] The cable can be electrically connected to the battery cell 220 to electrically connect the battery cell 220 to other components. Alternatively, the cable can be disconnected from the battery cell 220 and electrically connected to other components (such as the control box, high-voltage box, etc.).

[0040] Figure 3 This is a schematic diagram illustrating the interaction between the cable tie fixing device and the cable tie according to one or more embodiments. Figure 4 yes Figure 3 The diagram shown illustrates the structure of the cable tie fixing device. Figure 5A This is a schematic diagram of the fixing and installation of the cable tie fixing device according to one or more embodiments. Figure 5B yes Figure 5A The diagram shows the dimensions of the cable tie fixing device. Figure 6 yes Figure 4 The diagram shows a structural schematic of the cable tie fixing device from another perspective. The following is combined with... Figures 3-6 The cable tie fixing device 100 is described below.

[0041] Please refer to Figure 3 This specification also provides a cable tie fixing device 100 in some embodiments. The cable tie fixing device 100 has a first direction X and a second direction Y that are perpendicular to each other, and a third direction Z that is perpendicular to the first direction X and the second direction Y.

[0042] The cable tie fixing device 100 includes a fixing part 110 and a cable tie mounting part 120. The fixing part 110 extends along a first direction X and is fixedly disposed in the housing 210. For example, the fixing part 110 may be fixedly disposed in the receiving cavity of the housing 210. The cable tie mounting part 120 is connected to the cable tie 140 and is used to fix the cable tie 140.

[0043] In some embodiments, the fixing portion 110 extends along a first direction X. For example, the axis L1 of the fixing portion 110 is parallel to the first direction X, and the length direction of the fixing portion 110 is consistent with the first direction X. The fixing portion 110 and the cable tie mounting portion 120 are arranged along a second direction Y. That is, the fixing portion 110 and the cable tie mounting portion 120 are disposed at different positions in the second direction Y. For example, if the fixing portion 110 and the cable tie mounting portion 120 are orthographically projected onto a straight line parallel to the second direction Y, the intersection of their orthographically projected areas is only a portion of the orthographically projected area of ​​the fixing portion 110 or the cable tie mounting portion 120, or the aforementioned intersection is empty. In some embodiments, the fixing portion 110 and the cable tie mounting portion 120 can be disposed adjacent to each other in the second direction Y, and they can be in direct contact. For another example, the fixing portion 110 and the cable tie mounting portion 120 can be disposed spaced apart in the second direction Y, and they do not contact each other. By designing the relative positions of the fixing part 110 and the cable tie mounting part 120, the position of the fixing part 110 is offset from the position of the cable tie 140 mounted on the cable tie mounting part 120. That is, the position of the fixing part 110 is offset from the position of the cable bundled by the cable tie 140. Therefore, the fixing part 110 does not need to overlap with the cable in the radial direction (e.g., the first direction X), thus achieving an eccentric setting between the position of the fixing part 110 and the cable position. This makes the fixing position of the fixing part 110 more flexible, thereby improving the adaptability of the cable tie fixing device 100 to assembly areas with different shapes and sizes of different cables. While achieving stable cable fixing, it reduces the probability of interference between the cable and the cable tie fixing device 100 and other components. Simultaneously, the eccentric design of the fixing position of the fixing part 110 relative to the cable also makes the axial dimension of the cable tie fixing device 100 smaller, suitable for compact designs of battery devices 200 with limited internal space, and avoids excessive force applied by the cable tie 140 to the cable 150, which could damage the cable.

[0044] In some embodiments, the cable tie fixing device 100 may further include a connecting portion 130, and a cable tie mounting portion 120 is disposed at at least one end of the connecting portion 130 located in the second direction Y. The connecting portion 130 connects the fixing portion 110 and the cable tie mounting portion 120 to fix the cable tie 140 and the cable after the cable tie 140 is used to bundle the cable.

[0045] In some embodiments, the fixing part 110 and the cable tie mounting part 120 are spaced apart along the second direction Y, thereby increasing the degree of eccentricity of the fixing position of the fixing part 110 relative to the cable, further improving the flexibility of the fixing position of the fixing part 110, and further improving the adaptability of the cable tie fixing device 100 to assembly areas of different shapes and sizes of different cables.

[0046] The connecting portion 130 may have an extended dimension in the second direction Y to ensure that the fixing portion 110 and the cable tie mounting portion 120 are spaced apart along the second direction Y. For example, the length direction of the connecting portion 130 is consistent with the second direction Y.

[0047] It should be noted that the connecting part 130 should avoid extending in the first direction X as much as possible, so as to avoid the cable tie fixing device 100 being too large in the extension direction (first direction X) of the fixing part 110, to avoid the cable tie fixing device 100 squeezing the assembly area of ​​other components when fixing cables, and to avoid increasing the overall structural size of the battery device 200 and the electrical equipment.

[0048] The fixing part 110 can be fixedly disposed within the receiving cavity of the housing 210. For example, the fixing part 110 can be fixed to the inner wall or bottom plate near the cable in the housing 210. As another example, the fixing part 110 can be fixed to a structural beam near the cable in the receiving cavity. In some embodiments, the fixing part 110 can be... Figure 3 The cedar tree head structure shown includes multiple conical elastic blades (not shown) distributed axially. In the axial direction from the free end of the cedar tree head to the fixed end where the cedar tree head connects to the connecting part 130, the radial direction of the conical elastic blades gradually increases. That is, the small end of the conical elastic blade is closer to the free end, and the large end is closer to the fixed end. The mounting structure inside the housing 210 has a hole, the diameter of which is smaller than the radial dimension of the large end of the elastic blade and larger than the radial dimension of the small end of the elastic blade. When the cedar tree head is connected to the mounting structure, the free end of the cedar tree head is inserted into the hole of the mounting structure along the extension direction of the cedar tree head (first direction X), and the elastic blades pass through the hole sequentially. For any elastic blade, the blade is deformed by the sidewall of the hole when its small end enters the hole, recovers its deformation after passing through the hole, and abuts against the mounting structure with its large end. When the mounting structure abuts against the connecting part 130, the large end of the last elastic blade that passed through the hole abuts against the mounting structure, thus achieving the connection and fixation between the cedar tree head and the mounting structure.

[0049] In some embodiments, the cable tie fixing device 100 may include only one cable tie mounting portion 120, through which the cable tie 140 is mounted. The cable tie mounting portion 120 is disposed at one end of the connecting portion 130 along the second direction Y, and the fixing portion 110 is disposed at the other end of the connecting portion 130 or at a position between the two ends of the connecting portion 130.

[0050] In other embodiments, the cable tie fixing device 100 may include two cable tie mounting portions 120, through which cable ties 140 are respectively mounted. The two cable tie mounting portions 120 may be respectively disposed at two ends of the connecting portion 130 along the second direction Y. In the second direction Y, the fixing portion 110 is located between the two cable tie mounting portions 120.

[0051] Please refer to Figures 3-5B In some embodiments, the cable tie mounting portion 120 has a first reinforcing portion 121 protruding from the connecting portion 130 along the first direction X, such as Figure 5A As shown in the dashed box. The first reinforcing part 121 enhances the structural strength of the cable tie mounting part 120 and improves the working stability of the cable tie fixing device 100. On the other hand, the design of the first reinforcing part 121 can also increase the size or area of ​​the cable tie mounting part 120 in the first direction X, thereby providing a larger contact surface for the bundled cables and improving the stability of the cables.

[0052] Please refer to Figures 3-5B In some embodiments, the first reinforcing part 121 and the fixing part 110 are located on the same side of the connecting part 130 along the first direction X. In this case, the dimension h4 of the first reinforcing part 121 along the first direction X and the dimension h1 of the fixing part 110 along the first direction X overlap, thereby effectively reducing the overall dimension of the cable tie fixing device 100 along the first direction X, avoiding the cable tie fixing device 100 from squeezing the assembly area of ​​other components when fixing the cable, making the cable tie fixing device 100 suitable for battery devices 200 with limited space, and avoiding excessive force on the cable by the cable tie, which could damage the cable.

[0053] In some embodiments, on the side of the connecting portion 130 where the fixing portion 110 is provided, the area not covered by the first reinforcing portion 121 can serve as the connecting area S, such as... Figure 5B As shown. The connection area S can contact the mounting platform 260, and the fixing part 110 is fixedly connected to the mounting platform 260 to achieve a fixed connection between the cable tie fixing device 100 and the box 210. The mounting platform 260 can be one or more of the following supporting structures: the side wall, the bottom plate, or the structural beams inside the box 210.

[0054] Please refer to Figure 1 ,for Figure 1The cable tie fixing device 100 shown is located below the cable 150. Therefore, when fixing the cable 150, the cable tie fixing device 100 needs to take into account the assembly space of the cable tie 140. This results in a large assembly space occupied by the cable tie fixing device 100 along the axial direction (first direction X) of the fixing part 110. When the structural components (such as the cover, beam or control box, etc.) in the housing 210 of the battery device 200 cannot reserve more space in the axial direction of the fixing part 110 of the cable tie fixing device 100 due to their own functional limitations or compact design requirements, it is easy to cause the bundled cables 150 to squeeze and rub against each other, accelerate cable aging, and in severe cases, even cable breakage or partial short circuit may occur.

[0055] In the axial direction of the fixing part 110 (for example, Figure 1 (Up and down direction in the middle), the assembly space occupied by the cable tie fixing device 100 when fixing the cable 150 includes the assembly space dimension h1 of the cable tie 140 forming a loop, the dimension h2 of the fixing part 110, and the dimension h3 of the cable tie mounting part 120.

[0056] Please refer to Figure 5B , Figure 5B The cable tie fixing device 100 shown is designed with the relative positions of the cable tie mounting part 120 and the fixing part 110 in such a way that the cable tie fixing device 100 can be located on the side of the cable when fixing the cable. This allows the assembly space occupied by the cable tie fixing device 100 to overlap with the assembly space of the cable tie 140 forming a loop in the extending direction of the fixing part 110, thereby reducing the assembly space occupied by the cable tie fixing device 100 in the axial direction of the fixing part 110.

[0057] like Figure 5B As shown, in the axial direction (first direction X) of the fixing part 110, the dimension h4 of the first reinforcing part 121 is covered by the dimension h2 of the fixing part 110 and the dimension h3 of the connecting part 130. The assembly space dimension h1 of the cable tie 140 forming a loop overlaps with or even covers the dimension h2 of the fixing part 110 and the dimension h3 of the cable tie mounting part 120 (the dimension of the connecting part 130). At this time, the assembly space dimension occupied by the cable tie fixing device 100 is the sum of h2 and h3. Among them, the dimension h3 of the cable tie mounting part 120 refers to the dimension of the remaining part of the cable tie mounting part 120 after removing the first reinforcing part 121, such as the dimension of the main body 123 mentioned later. The dimension of this remaining part is the same as the dimension of the connecting part 130.

[0058] Compared to Figure 1 The dimensions (h1+h2+h3) of the cable tie fixing device 100 in the axial direction of the fixing part 110 are shown. Figure 5BThe cable tie fixing device 100 shown has a significantly smaller axial dimension (h2+h3) in the fixing part 110. This means that even when structural components (such as the cover, beam, or control box) in the housing 210 of the battery device 200 cannot reserve more space in the axial direction of the fixing part 110 of the cable tie fixing device 100 due to their own functional limitations or compact design requirements, the cable tie fixing device 100 can avoid squeezing the assembly area of ​​other components when fixing cables, thereby improving the safety of cable use and optimizing the space utilization rate within the housing 210 of the battery device 200.

[0059] In other embodiments, the first reinforcing part 121 may be located on a different side of the connecting part 130 along the first direction X from the fixing part 110. In this case, in the first direction X, the dimension h4 of the first reinforcing part 121 is not covered by the dimension h2 of the fixing part 110 or the dimension h3 of the connecting part 130. The assembly space occupied by the cable tie fixing device 100 is the sum of h2, h3, and h4. Although relatively Figure 5B The cable tie fixing device 100 shown has an increased size in the axial direction of the fixing part 110, but it can still maintain a small size, avoiding interference between the cable tie fixing device 100 and other components. It is suitable for lightweight and compact battery devices, improves the safety of cable use, and optimizes the space utilization within the housing 210 of the battery device 200.

[0060] Please refer to Figure 3 , Figure 5A , Figure 5B and Figure 6 In some embodiments, the cable tie mounting portion 120 further has a second reinforcing portion 122 that protrudes Z-directly from the connecting portion 130, such as Figure 6 As shown in the dashed box, the design of the second reinforcing part 122 can further enhance the structural strength of the cable tie mounting part 120 and improve the working stability of the cable tie fixing device 100. At the same time, the second reinforcing part 122 can also increase the size or area of ​​the cable tie mounting part 120 in the third direction Z, thereby providing a larger contact surface for the bundled cables and improving the stability of the cables.

[0061] In some embodiments, the first reinforcing part 121 and the second reinforcing part 122 may be the same structure, which protrudes from the connecting part 130 in both the first direction X and the third direction Z.

[0062] Please refer to Figure 3 In some embodiments, the connecting portion 130 may have a groove 131 on its side along the third direction Z. By designing the groove 131, the structural strength of the connecting portion 130 can be ensured while reducing the material used in the connecting portion 130, saving costs and reducing weight.

[0063] In some embodiments, the area of ​​the connecting portion 130 where the fixing portion 110 is provided protrudes more along the third direction Z than other areas, to further enhance the structural strength of the connecting portion 130. For example, as Figure 4 , Figure 6 As shown, in a reference plane perpendicular to the first direction X, the projection of the area where the fixing part 110 is provided on the connecting part 130 can be a circle.

[0064] In some embodiments, different cable tie fastening devices 100 can be used for different cables, and the dimensions of the connecting portion 130 of the different cable tie fastening devices 100 along the second direction Y can be determined based on the assembly space of the corresponding cables. In other embodiments, the connecting portion 130 can adopt a telescopic structure to adapt to the assembly space of different cables, so that one cable tie fastening device 100 can be used for multiple cables.

[0065] Please refer to Figure 3 , Figure 5A , Figure 5B and Figure 6 The cable tie mounting part 120 includes a main body 123 connected to the connecting part 130, and a first reinforcing part 121 disposed on the main body 123. The main body 123 and the first reinforcing part 121 can be integrally formed or separately connected; the main body 123 and the connecting part 130 can be integrally formed or separately connected.

[0066] In some embodiments, the main body 123 is provided with a groove 124, and a mounting post 125 is provided in the groove 124. The two ends of the mounting post 125 are fixed to two opposite sidewalls of the groove 124. A clearance gap is formed between the mounting post 125 and the bottom wall of the groove 124. The cable tie 140 passes through this clearance gap, and the mounting post 125 is located within the loop formed by the cable tie 140, thus enabling the installation of the cable tie 140. Figure 3 As shown.

[0067] In some embodiments, the mounting post 125 extends along a third direction Z, and correspondingly, the cable also extends along a third direction Z. This makes the extension directions of the connecting part 130 and the fixing part 110 perpendicular to the cable extension direction, allowing the fixing position of the fixing part 110 to be eccentrically positioned relative to the cable. This makes the fixing position of the fixing part 110 more flexible, thereby improving the adaptability of the cable tie fixing device 100 to assembly areas with different shapes and sizes of different cables. Simultaneously, the design of the fixing position of the fixing part 110 being eccentrically positioned relative to the cable also results in a smaller axial dimension of the cable tie fixing device 100, making it suitable for compact designs of battery devices 200 with limited internal space, and preventing excessive force applied to the cable by the cable tie, which could damage the cable.

[0068] In other embodiments, the mounting post 125 may also extend along the first direction X. Correspondingly, the extension direction of the cable is also along the first direction X. This allows the fixing position of the fixing part 110 to be eccentrically set relative to the cable, making the fixing position of the fixing part 110 more flexible. This improves the adaptability of the cable tie fixing device 100 to assembly areas of different shapes and sizes of different cables.

[0069] Please refer to Figure 3 The cable tie 140 includes a cable tie head 141 and a tie body 142. One end of the tie body 142 is fixedly connected to the cable tie head 141, and the other end of the tie body 142 passes through the cable tie mounting portion 120 of the cable tie fixing device 100 and extends into the cable tie head 141 to form a loop for fixing the cable. For example, the other end of the tie body 142 can pass through the clearance gap between the groove 124 of the main body 123 and the mounting post 125 and extend into the cable tie head 141 to form a loop, with the mounting post 125 located within the loop to fix the cable.

[0070] Please refer to Figure 5B and Figure 6 In some embodiments, the ends of the cable tie mounting portion 120 and the connecting portion 130 are rotatably connected about a second direction Y, that is, the ends of the cable tie mounting portion 120 and the connecting portion 130 can rotate relative to each other about the second direction Y. The axis of rotation is an axis L2 parallel to the second direction Y. Specifically, the main body 123 of the cable tie mounting portion 120 can be rotatably connected to the end of the connecting portion 130 about the second direction Y. With the cable (cable tie 140) in a fixed position, the connecting portion 130 and the fixing portion 110 can rotate about the second direction Y, thereby adjusting the orientation of the fixing portion 110 to further increase the installation flexibility of the cable tie fixing device 100. This allows the user to flexibly adjust the cable tie fixing device 100 based on the internal spatial structure and component layout of the housing 210, avoiding interference between the cable tie fixing device 100 and other components.

[0071] In some embodiments, the ends of the cable tie mounting portion 120 and / or the connecting portion 130 are provided with a first locking structure (not shown in the figures), which can lock or unlock the rotatable connection between the cable tie mounting portion 120 and the ends. Specifically, the body 123 of the cable tie mounting portion 120 and the ends of the connecting portion 130 may be provided with the first locking structure.

[0072] For example, the main body 123 has a rotating shaft extending into the connecting portion 130 along the second direction Y. The first locking structure includes a through hole provided on the connecting portion 130 and a pin. The pin can extend into the through hole and abut against the rotating shaft to restrict the rotation of the rotating shaft, thereby locking the rotatable connection between the cable tie mounting portion 120 and the end of the connecting portion 130. When the pin is pulled out along the through hole and no longer abuts against the rotating shaft, the pin no longer restricts the rotation of the rotating shaft, thereby unlocking the rotatable connection between the cable tie mounting portion 120 and the end of the connecting portion 130.

[0073] Please refer to Figure 3 , Figure 5B and Figure 6 In some embodiments, the fixing part 110 and the connecting part 130 are rotatably connected about a first direction X. That is, the fixing part 110 and the connecting part 130 can rotate relative to each other about a second direction Y. The axis of rotation is an axis L1 parallel to the first direction X. With the fixing part 110 fixed in a fixed position, the connecting part 130, the cable tie mounting part 120, and the cable tie 140 can rotate about the first direction X, thereby adjusting the extension direction of the cable. Even when the cable tie fixing device 100 fixes the cable, the cable still has room for bending and adjustment. When the cable is fixed and assembled by other cable tie fixing devices 100, or when the cable is maintained later, the cable's arrangement and extension direction can be flexibly changed, avoiding damage to the core wire due to forced bending, and improving the ease of installation and removal and maintainability of the cable.

[0074] In some embodiments, the fixing part 110 and / or the connecting part 130 are provided with a second locking structure (not shown in the figure), which can lock or unlock the rotatable connection between the fixing part 110 and the connecting part 130.

[0075] For example, the fixing part 110 has a rotating shaft extending into the connecting part 130 along a first direction X. The rotating shaft passes through the connecting part 130 along the first direction X, and the free end of the rotating shaft away from the fixing part 110 is flush with the upper side of the connecting part 130 away from the fixing part 110. The second locking structure may include a first limiting groove disposed at the free end of the rotating shaft away from the fixing part 110, a second limiting groove disposed on the upper side of the connecting part 130 away from the fixing part 110, and a limiting rod. The upper side of the connecting part 130 may have multiple second limiting grooves, which are distributed around the free end of the rotating shaft circumferentially, and extend radially along the rotating shaft. During the rotation of the rotating shaft, the first limiting groove also rotates, thereby sequentially communicating collinearly with different second limiting grooves. When the first limiting groove and any second limiting groove are collinearly connected, the limiting rod is inserted into both the first and second limiting grooves, allowing the limiting rod to pass through both simultaneously. Through the cooperation of the first and second limiting grooves and the limiting rod, the rotation of the rotating shaft relative to the connecting part 130 is prevented, thus locking the rotatable connection between the fixing part 110 and the connecting part 130. When the limiting rod is removed from the first and second limiting grooves, the rotatable connection between the fixing part 110 and the connecting part 130 is unlocked.

[0076] Some embodiments of this specification also provide an electrical device including a battery device 200, which serves as a power source for the electrical device and / or an energy storage unit for the electrical device.

[0077] The beneficial effects that the embodiments of this specification may bring include, but are not limited to: (1) by designing the fixing part to extend along the first direction and the fixing part and the cable tie mounting part to be spaced apart along the second direction, the fixing position of the fixing part can be set off-center relative to the cable, making the fixing position of the fixing part more flexible and improving the adaptability of the cable tie fixing device to assembly areas of different shapes and sizes of different cables; (2) by designing the fixing position of the fixing part to be set off-center relative to the cable, the axial dimension of the cable tie fixing device in the fixing part is also smaller, which is suitable for compact battery devices with small internal space and avoids the cable tie from applying too much force to the cable, causing cable damage; (3) by designing the first reinforcing part and the fixing part to be located on the same side of the connecting part along the first direction, the axial dimension of the cable tie fixing device in the fixing part is further reduced, improving the adaptability of the cable tie fixing device to compact battery devices with small internal space, improving the safety of cable use, and optimizing the space utilization rate inside the battery device box.
