Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery device and an electrical appliance. Background Technology

[0002] Battery devices are widely used in electronic devices such as mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools, etc.

[0003] When assembling a battery device, it is necessary to install the electronic control components and their brackets. How to reduce the possibility of the electronic control components and brackets being installed in reverse is a research direction in battery technology. Utility Model Content

[0004] This application provides a battery device and an electrical appliance that can reduce the possibility of the electronic control components and the bracket being installed in reverse.

[0005] In a first aspect, embodiments of this application provide a battery device, including a battery housing, battery cells, a bracket, and an electronic control assembly, wherein at least one battery cell is installed in the battery housing; the bracket is installed in the battery housing, and the electronic control assembly is electrically connected to the battery cells and mounted on the bracket; wherein the electronic control assembly has a wiring port, the wiring port being electrically connected to the battery cells via wiring, and the bracket having a first foolproof part configured to avoid the wiring port when the electronic control assembly is installed on the bracket in a preset manner, and to block at least a portion of the wiring port when the electronic control assembly is installed on the bracket in a non-preset manner. Partially; and / or, the bracket includes a bracket body, a first connecting component, and a second connecting component. The bracket body includes a first end and a second end disposed opposite to each other. The first connecting component is disposed at the first end, and the second connecting component is disposed at the second end. Both ends of the electronic control component are respectively connected to the first connecting component and the second connecting component. The first connecting component has at least two spaced-apart first connecting portions that cooperate with the electronic control component. The second connecting component has at least two spaced-apart second connecting portions that cooperate with the electronic control component. The spacing between two adjacent first connecting portions and the spacing between two adjacent second connecting portions are unequal.

[0006] By adopting the above technical solution, the spacing between two adjacent first connecting parts and the spacing between two adjacent second connecting parts are designed to be unequal. This allows the operator to visually determine where the electronic control component connects to the first connecting part and where it connects to the second connecting part based on the spacing when assembling the electronic control component to the bracket. This reduces the possibility of the electronic control component being installed backwards on the bracket. The first and second connecting parts not only serve to connect the electronic control component but also act as a foolproof mechanism, serving multiple purposes in one unit. Furthermore, by configuring the first foolproof part, if the electronic control component is assembled to the bracket in a non-preset manner, the first foolproof part blocks the wiring port, allowing the operator to detect the reverse installation and correct the installation posture of the electronic control component. This also serves as a foolproof mechanism, reducing the possibility of the electronic control component and the bracket being installed backwards.

[0007] In some embodiments of this application, the difference between the spacing between two adjacent first connecting portions and the spacing between two adjacent second connecting portions ranges from 3 mm to 15 mm.

[0008] By adopting the above technical solution, the difference between the spacing of the two first connecting parts and the spacing of the two adjacent second connecting parts is designed to be 3mm to 15mm, which not only meets the error prevention requirements but also facilitates processing.

[0009] In some embodiments of this application, the difference between the spacing between two adjacent first connecting portions and the spacing between two adjacent second connecting portions ranges from 5 mm to 10 mm.

[0010] By adopting the above technical solution, the difference between the distance between the two first connecting parts and the distance between the two adjacent second connecting parts is designed to be 5mm to 10mm, which makes the difference between the distance between the two first connecting parts and the distance between the two adjacent second connecting parts easier to identify with the naked eye and more convenient to process.

[0011] In some embodiments of this application, any two first connecting portions are arranged at intervals along a first direction, and any two second connecting portions are arranged at intervals along the first direction, wherein the first direction intersects the arrangement direction from the first connecting component to the second connecting component.

[0012] By adopting the above technical solution, the first connecting part and the second connecting part are designed to be arranged along the first direction. After the electronic control component is installed and docked with the electronic control frame, the first connecting part and the second connecting part constrain and fix the electronic control component along their arrangement direction. At the same time, the two first connecting parts and the two second connecting parts simultaneously constrain and fix the electronic control component along the first direction, which improves the stability of the electronic control component after installation.

[0013] In some embodiments of this application, the first connecting portion includes a first positioning post, and the electronic control component is provided with a first positioning hole that is inserted and engaged with the first positioning post; or, the first connecting portion includes a first positioning hole, and the electronic control component is provided with a first positioning post that is inserted and engaged with the first positioning hole.

[0014] By adopting the above technical solution, the electrical control components are connected to the bracket through the cooperation of the first positioning post and the first positioning hole. This not only simplifies the structure, but also allows one first positioning post to connect to multiple stacked circuit boards, achieving multi-purpose functionality.

[0015] In some embodiments of this application, the second connecting portion includes a second positioning post, and the electronic control component is provided with a second positioning hole that is inserted and engaged with the second positioning post; or, the second connecting portion includes a second positioning hole, and the electronic control component is provided with a second positioning post that is inserted and engaged with the second positioning hole.

[0016] By adopting the above technical solution, the electronic control components and the bracket are connected through the cooperation of the second positioning post and the second positioning hole. This not only simplifies the structure, but also allows one second positioning post to connect to multiple stacked circuit boards, achieving multi-purpose functionality.

[0017] In some embodiments of this application, the first end has at least two spaced third connecting portions on the side away from the electronic control component, which cooperate with and connect to the battery housing; the second end has at least two spaced fourth connecting portions on the side away from the electronic control component, which cooperate with and connect to the battery housing; and the spacing between two adjacent third connecting portions and the spacing between two adjacent fourth connecting portions are not equal.

[0018] By adopting the above technical solution, the spacing between two adjacent third connecting parts and the spacing between two adjacent fourth connecting parts are designed to be unequal. This allows the operator to visually determine the positions of the two third connecting parts and the two fourth connecting parts on the battery box when the bracket is assembled to the battery box, thereby reducing the possibility of the electronic control components being assembled backwards. The third connecting parts not only serve to connect the electronic control components but also play a role in preventing mistakes.

[0019] In some embodiments of this application, the difference between the spacing between two adjacent third connecting portions and the spacing between two adjacent fourth connecting portions ranges from 10 mm to 80 mm.

[0020] By adopting the above technical solution, the difference between the spacing between two adjacent third connecting parts and the spacing between adjacent fourth connecting parts is designed to be 10mm to 80mm, which not only meets the error prevention requirements but also facilitates processing.

[0021] In some embodiments of this application, the difference between the spacing between two adjacent third connecting portions and the spacing between two adjacent fourth connecting portions ranges from 40 mm to 50 mm.

[0022] By adopting the above technical solution, the difference between the spacing of two adjacent third connecting parts and the spacing of the adjacent fourth connecting parts is designed to be 40mm to 50mm, which makes the spacing between the two third connecting parts and the spacing between the two adjacent fourth connecting parts easier to identify with the naked eye and more convenient to process.

[0023] In some embodiments of this application, any two of the third connecting portions are spaced apart along a first direction, and any two of the fourth connecting portions are spaced apart along the first direction, the first direction intersecting the arrangement direction from the first connecting component to the second connecting component.

[0024] By adopting the above technical solution, the third and fourth connecting parts are designed to be arranged along the first direction. After the bracket is installed and connected to the battery box, the connection structure formed by the two third connecting parts and the connection structure formed by the two third connecting parts along the arrangement direction of the two connection structures constrain and fix the bracket. At the same time, the two third connecting parts and the two fourth connecting parts simultaneously constrain and fix the bracket along the first direction, which improves the stability of the bracket after it is installed in the battery box.

[0025] In some embodiments of this application, the third connecting portion includes a first connecting ear extending outward from the bracket body, the first connecting ear having a first connecting hole for engaging with the battery housing; and / or, the fourth connecting portion includes a second connecting ear extending outward from the bracket body, the second connecting ear having a second connecting hole for engaging with the battery housing.

[0026] The above technical solution utilizes the first connecting hole of the first connecting ear and the second connecting hole of the second connecting ear to connect to the battery box, resulting in a simple structure that is easy to assemble.

[0027] In some embodiments of this application, the third connecting portion includes a first connecting ear extending outward from the bracket body. The battery housing has a first mounting surface for connecting the first connecting ear. The first connecting ear includes a first bent portion and a second bent portion. One end of the first bent portion is connected to the bracket body. The first bent portion extends in a direction away from the electronic control component. The other end of the first bent portion is connected to the second bent portion. The second bent portion is connected to the first bent portion at an angle, and the surface of the second bent portion facing the first mounting surface contacts the first mounting surface.

[0028] By adopting the above technical solution, the first bending part creates a certain gap between the bracket body and the battery box to facilitate heat dissipation of the bracket body, and the second bending part facilitates the first connecting ear to fit and connect with the battery box.

[0029] In some embodiments of this application, the bracket body has a first protruding portion extending outward on at least one side along a first direction, and the first protruding portion has a fifth connecting portion and / or a sixth connecting portion, the fifth connecting portion being used to fix the wire harness, and the sixth connecting portion being used to fix the conductive busbar.

[0030] By adopting the above technical solution, the fifth connecting part is used to facilitate the binding and fixing of the wire harness, reducing the possibility of wear between the bracket and the wire harness, improving the performance stability of the wire harness, and optimizing the internal wiring of the battery device; the sixth connecting part is used to bind and fix the conductive busbar, reducing the possibility of wear between the bracket and the conductive busbar, and improving the position and structural stability of the conductive busbar.

[0031] In some embodiments of this application, the fifth connecting portion includes a first through hole and a first binding strap passing through the first through hole.

[0032] The above technical solution uses a first binding strap that passes through the first through hole to fix the wire harness. The structure is simple and different specifications of first binding straps can be selected for wire harnesses of different specifications, which improves the universality of the fifth connection part.

[0033] In some embodiments of this application, the first protrusion includes a third bent portion and a fourth bent portion. The third bent portion extends in a direction away from the connection between the bracket body and the battery box body. The fourth bent portion is connected to the third bent portion at an angle and extends in a direction away from the bracket body.

[0034] By adopting the above technical solution, the third bend creates a certain clearance space between the fourth bend and the bracket body, which facilitates the routing of wire harnesses and the placement of conductive busbars.

[0035] In some embodiments of this application, the bracket body has a weight-reducing hole, which faces the electronic control component.

[0036] By adopting the above technical solution, the weight reduction holes can reduce the weight of the bracket body and the materials required, saving costs and increasing the energy density of the battery device. Furthermore, the weight reduction holes facing the electronic control components can improve the heat dissipation performance of the electronic control components.

[0037] In some embodiments of this application, the length of the weight-reducing hole is not less than half the length of the support body, and / or the width of the weight-reducing hole is not less than half the width of the support body.

[0038] By adopting the above technical solution, the weight and material consumption of the bracket body can be further reduced, thereby further improving the energy density of the battery device and the heat dissipation performance of the electronic control components.

[0039] In some embodiments of this application, the wall of the weight-reducing hole is recessed in a direction away from the electronic control component to form a reinforcing rib.

[0040] By adopting the above technical solution, the structural strength of the support body can be improved by using reinforcing ribs.

[0041] In some embodiments of this application, the first error-proof part includes a fifth bending portion and a sixth bending portion. The fifth bending portion extends outward from the connection between the bracket body and the battery box body. The sixth bending portion is connected to the fifth bending portion at an angle and extends outward from the bracket body.

[0042] By adopting the above technical solution, the fifth bend is designed to extend along the side away from the connection between the bracket body and the battery box, so that the fifth bend has a certain stopping height on the bracket body, which can play a better role in preventing mistakes; the sixth bend is set to extend in the direction away from the bracket body, which can reduce the risk of injury caused by the fifth bend being too abrupt.

[0043] In some embodiments of this application, the first end has a third connecting portion that mates with the battery housing on the side opposite to the electronic control component, and the second end has a fourth connecting portion that mates with the battery housing on the side opposite to the electronic control component. The bracket body has a second anti-mistake portion on the fourth connecting portion. The battery housing has a first wall facing the first end and a second wall facing the second end. The second wall is spaced apart from the second anti-mistake portion, or the second wall has a receiving space, and at least a portion of the second anti-mistake structure is received in the receiving space.

[0044] By adopting the above technical solution, a second anti-misfit part is provided on the third or fourth connecting part. When the bracket tends to be installed backwards into the battery box, the second anti-misfit part interferes with the first wall and cannot be assembled, thereby reducing the possibility of the bracket being installed backwards into the box.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application 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 description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0066] In this application, the reference to "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 in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication 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.

[0068] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, H and / or B can represent: H existing alone, H and B existing simultaneously, and B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0069] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0070] In this application, "multiple" means two or more (including two).

[0071] Currently, battery devices are being used more and more widely. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As the application areas of battery devices continue to expand, the market demand is also constantly increasing.

[0072] The battery assembly includes a battery housing, individual battery cells located within the housing, and electronic control components. The electronic control components (such as a battery management system, BMS) are typically mounted securely within the battery housing using brackets. During installation, the electronic control components are connected to the battery housing via the brackets, thereby improving their stability and safety.

[0073] However, there are no clear positioning and installation instructions between the electrical control components and the bracket, which makes it easy for the electrical control components to be installed backwards when they are installed on the bracket, affecting production efficiency.

[0074] Therefore, reducing the possibility of incorrect installation of electronic control components is an important issue in the research and development of battery devices and related components.

[0075] In view of this, this application provides a technical solution in which the spacing between the two first connecting parts of the bracket and the spacing between the two adjacent second connecting parts are designed to be unequal. The first connecting parts and the second connecting parts not only serve to connect the electronic control components, but also serve as a foolproof function, thus serving multiple purposes in one unit. In addition, by setting the first foolproof part on the bracket, the wiring of the wiring port can be blocked when the installation is not in the preset manner, so that the operator can know that it is installed backwards and thus change the installation posture of the electronic control components, which also serves as a foolproof function and reduces the possibility of the electronic control components and the bracket being installed backwards.

[0076] The battery cells described in the embodiments of this application are applicable to batteries and electrical devices that use batteries.

[0077] Electrical equipment can include vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools, etc. Vehicles can be gasoline-powered cars, natural gas-powered cars, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. Spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc. This application does not impose any special limitations on the above-mentioned electrical equipment.

[0078] For ease of explanation, the following embodiments use a vehicle as an example of electrical equipment.

[0079] Combined with appendix Figure 1 As shown, vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery device 100 is installed inside vehicle 1000, and the battery device 100 can be located at the bottom, front, or rear of vehicle 1000. The battery device 100 can be used to power vehicle 1000; for example, the battery device 100 can serve as the operating power source for vehicle 1000. Vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of vehicle 1000 during starting, navigation, and driving.

[0080] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0081] Combined with appendix Figure 2 To be continued Figure 6 As shown, this application provides a battery device 100, including a battery housing 10, a battery cell 20, a bracket 30, and an electronic control component 40.

[0082] Combined with appendix Figure 7 As shown in the figure, this application embodiment also provides a battery device 100, including a battery housing 10, a battery cell 20, a bracket 30, and an electronic control component 40.

[0083] "Preset mode" means that the electronic control component 40 is installed according to the design method when it is installed on the bracket 30, and the wiring of the electronic control component 40 and the first foolproof part will not interfere. "Non-preset mode" means that the orientation of the electronic control component 40 is opposite to the design method, and the wiring of the electronic control component 40 and the first foolproof part 313 will interfere with the assembly.

[0084] The battery housing 10 of this embodiment provides a space for accommodating the battery cell 20. The battery housing 10 can adopt various structures. In some embodiments, the battery housing 10 may include a first portion 11 and a second portion 12, which overlap each other, jointly defining a cavity for accommodating the battery cell 20. Both the first portion 11 and the second portion 12 can be hollow structures with one open end, with the second portion 12 covering the open side of the first portion 11, so that the first portion 11 and the second portion 12 jointly define the accommodating space; alternatively, the second portion 12 can be a plate-like structure, and the first portion 11 can be a hollow structure with one open side, with the open side of the second portion 12 covering the open side of the first portion 11.

[0086] The battery device 100 mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells 20 to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack. A battery generally includes a housing for encapsulating one or more battery cells 20.

The positive current collector includes a positive electrode coating area and a positive electrode tab connected to the positive electrode coating area.

[0090] To reduce the possibility of the electronic control component 40 being installed backwards, this embodiment improves the bracket 30 by including at least two spaced first connecting parts 321 in the first connecting component 32 and at least two spaced second connecting parts 331 in the second connecting component 33. The distance b between two adjacent first connecting parts 321 and the distance c between two adjacent second connecting parts 331 are not equal.

[0091] It should be noted that the distance between two adjacent first connecting parts 321 can be either the center distance between them or the distance between their outer contours. Similarly, the distance between two adjacent second connecting parts 331 can be either the center distance between them or the distance between their outer contours. Under the condition that the first connecting parts 321 and the second connecting parts 331 have the same specifications and structure, the result is the same whether the difference between b and c is calculated using the aforementioned center distance or the distance between their outer contours.

[0092] The spacing between two adjacent first connecting portions 321 and the spacing between two adjacent second connecting portions 331 in this embodiment refer to the two first connecting portions 321 and the two second connecting portions 331 in the same row.

[0093] The spacing between two adjacent first connecting parts 321 and the spacing between two adjacent second connecting parts 331 are designed to be unequal. This allows the operator to visually determine where the electronic control component 40 aligns with the first connecting part 32 and where it aligns with the second connecting part 33 when assembling the electronic control component 40 onto the bracket 30. This reduces the possibility of the electronic control component 40 being assembled backwards onto the bracket 30. The first connecting part 321 and the second connecting part 331 not only serve to connect the electronic control component 40 but also provide a foolproof function, making it a multi-functional unit.

[0094] In addition, a first foolproof part 313 can be set. The first foolproof part 313 is used to block the wiring port, so that the operator can know that it is installed in reverse and thus change the installation posture of the electrical control component 40. It also plays a foolproof role and reduces the possibility that the electrical control component 40 and the bracket are installed in reverse.

[0095] The above technical solutions include at least three implementation methods, one of which is as follows: Figure 3-6 As shown, the bracket 30 at this time does not have the first anti-fooling part 313; it simply designs the spacing between the two first connecting parts 321 and the spacing between the two adjacent second connecting parts 331 to be unequal. Another type is as follows... Figure 7 As shown, the bracket 30 at this time is provided with a first anti-fooling part 313, but the distance between the two first connecting parts 321 and the distance between the two adjacent second connecting parts 331 are equal. Another embodiment is that the bracket 30 is provided with a first anti-fooling part 313, and the distance between the two first connecting parts 321 and the distance between the two adjacent second connecting parts 331 are unequal (not shown in the figure).

[0096] The distance b between the two first connecting parts 321 and the distance c between the two adjacent second connecting parts 331 are not equal. It can be that b is greater than c or b is less than c. The accompanying drawings of this embodiment show that b is less than c.

[0097] Combined with appendix Figure 5As shown, in some embodiments, the difference between the spacing b between two adjacent first connecting portions 321 and the spacing c between two adjacent second connecting portions 331 ranges from 3 mm to 15 mm.

[0098] The difference between b and c can be 3mm, 5mm, 7mm, 9mm, 11mm, 13mm, and 15mm, etc., which will not be listed one by one in this embodiment.

[0099] The reason for adopting the above design is that if the difference between b and c is too large, one of b and c must be larger or smaller. Taking a larger b as an example, the size of the bracket 30 needs to be increased to achieve a larger distance between the two first connecting parts 321, which increases production costs. Taking a smaller c as an example, it is not only difficult to process, but also the fixing effect of the electronic control component 40 in the arrangement direction of the two second connecting parts 331 is not good.

[0100] Therefore, in this embodiment, the difference between the spacing between the two first connecting parts 321 and the spacing between the two adjacent second connecting parts 331 is designed to be 3mm to 15mm, which satisfies the error prevention requirements while facilitating processing.

[0101] In some examples, optionally, the difference between the spacing between two adjacent first connecting portions 321 and the spacing between two adjacent second connecting portions 331 ranges from 5 mm to 10 mm.

[0102] The above values ​​further limit the difference between b and c. Specifically, the difference between b and c can be 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm, etc. This embodiment will not list them one by one.

[0103] The difference between the spacing between the two first connecting parts 321 and the spacing between the two adjacent second connecting parts 331 is designed to be 5mm to 10mm, which makes the difference between the spacing between the two first connecting parts 321 and the spacing between the two adjacent second connecting parts 331 easier to identify with the naked eye and also more convenient to process.

[0104] In some examples, optionally, any two first connecting portions 321 are arranged at intervals along a first direction X, and any two second connecting portions 331 are arranged at intervals along a first direction X, the first direction X intersecting the arrangement direction of the first connecting component 32 to the second connecting component 33.

[0105] In this embodiment, the first direction X can be the width direction of the bracket 30, and the arrangement direction of the first connecting component 32 to the second connecting component 33 is the second direction Y in the figure. The second direction Y can be the length direction of the bracket 30.

[0106] The first connecting part 321 and the second connecting part 331 are designed to be arranged along the first direction X. After the electronic control component 40 is installed and docked with the electronic control frame, the first connecting part 321 and the second connecting part 331 constrain and fix the electronic control component 40 along the second direction Y. At the same time, the two first connecting parts 321 and the two second connecting parts 331 simultaneously constrain and fix the electronic control component 40 along the first direction X, so that the electronic control component 40 is fixed and constrained in the first direction X and the second direction Y, thereby improving the stability of the electronic control component 40 after installation.

[0107] Combined with appendix Figure 3-5 As shown, in some examples, optionally, the first connecting part 321 includes a first positioning post, and the electronic control component 40 is provided with a first positioning hole (not shown in the figure) that is inserted into the first positioning post; or, the first connecting part 321 includes a first positioning hole, and the electronic control component 40 is provided with a first positioning post that is inserted into the first positioning hole.

[0108] In some examples, the second connection portion 331 may optionally include a second positioning post, and the electronic control component 40 may have a second positioning hole (not shown in the figure) that engages with the second positioning post; or, the second connection portion 331 may include a second positioning hole, and the electronic control component 40 may have a second positioning post that engages with the second positioning hole.

[0109] The electrical control component 40 is connected to the bracket 30 by the cooperation of the positioning post and the positioning hole. This not only simplifies the structure, but also allows one positioning post to connect to multiple stacked circuit boards, achieving multi-purpose functionality.

[0110] In some embodiments, the first and second positioning posts of this embodiment may be provided with external threads (not shown in the figure). After the electronic control assembly 40 is assembled, the first and second positioning posts can extend out of the top of the electronic control assembly 40 and the bolts can be used to lock the electronic control assembly 40, thereby locking and fixing the electronic control assembly 40 in a third direction Z that intersects the first direction X and the second direction Y respectively, thereby improving the stability of the installation of the electronic control assembly 40.

[0111] Combined again with the appendix Figure 5 As shown, in some examples, optionally, the first end 311 has at least two spaced third connection portions 314 on the side opposite to the electronic control assembly 40, which are connected to the battery housing 10, and the second end 312 has at least two spaced fourth connection portions 315 on the side opposite to the electronic control assembly 40, which are connected to the battery housing 10. The distance d between two adjacent third connection portions 314 and the distance e between two adjacent fourth connection portions 315 are not equal.

[0112] The third connecting part 314 and the fourth connecting part 315 are used to dock with the battery box 10. The third connecting part 314 and the fourth connecting part 315 can dock with the battery box 10 through mechanical connection methods such as bolt connection, snap connection and plug-in connection.

[0113] The distance d between two adjacent third connecting parts 314 and the distance e between two adjacent fourth connecting parts 315 are designed to be unequal. It can be that d is less than e or that d is greater than e. The accompanying drawings of this embodiment show that d is less than e.

[0114] This allows the operator to visually determine, based on the spacing, where the two third connecting parts 314 and the two fourth connecting parts 315 align with the battery box 10 when the bracket 30 is assembled to the battery box 10. This reduces the possibility of the electronic control component 40 being assembled backwards onto the bracket 30. The third connecting parts 314 and the fourth connecting parts 315 not only serve to connect the battery box 10 but also act as a foolproof mechanism.

[0115] It should be noted that the distance between two adjacent third connecting parts 314 can be either the center distance between them or the distance between their outer contours. Similarly, the distance between two adjacent fourth connecting parts 315 can be either the center distance between them or the distance between their outer contours. Under the condition that the third connecting parts 314 and the fourth connecting parts 315 have the same specifications and structure, the result is the same whether the difference between d and e is calculated using the aforementioned center distance or the distance between their outer contours.

[0116] In some examples, optionally, the difference between the spacing d between two adjacent third connecting portions 314 and the spacing e between two adjacent fourth connecting portions 315 ranges from 10 mm to 80 mm.

[0117] The difference between d and e can be 10mm, 20mm, 30mm, 40mm, 60mm, 70mm and 80mm, etc., which will not be listed one by one in this embodiment.

[0118] The reason for adopting the above design is that if the difference between d and e is too large, then one of d and e must be larger or smaller. Taking a larger e as an example, it is necessary to increase the size of the bracket 30 and the width of the beam connecting the battery box 10 and the bracket 30 to achieve a larger spacing between the two third connecting parts 314, which is difficult to process and increases production costs. Taking a smaller d as an example, it is not only difficult to process, but also the fixing effect of the bracket 30 in the arrangement direction of the two fourth connecting parts 315 is not good.

[0119] The difference between the spacing between two adjacent third connecting parts 314 and the spacing between adjacent fourth connecting parts 315 is designed to be 10mm to 80mm, which satisfies the error-proof requirements while facilitating processing.

[0120] In some examples, optionally, the difference between the spacing d between two adjacent third connecting portions 314 and the spacing e between two adjacent fourth connecting portions 315 ranges from 40 mm to 50 mm.

[0121] For example, the difference between d and e can be 40mm, 42mm, 45mm, 47mm, and 50mm, etc., which will not be listed one by one in this embodiment.

[0122] The difference between the spacing between two adjacent third connecting parts 314 and the spacing between two adjacent fourth connecting parts 315 is designed to be 40mm to 50mm, which makes the spacing between the two third connecting parts 314 and the spacing between the two adjacent fourth connecting parts 315 easier to identify with the naked eye and more convenient to process.

[0123] In some examples, optionally, any two third connecting portions 314 are arranged at intervals along the first direction X, and any two fourth connecting portions 315 are arranged at intervals along the first direction X, the first direction X intersecting the arrangement direction of the first connecting component 32 to the second connecting component 33.

[0124] Of course, in addition to arranging the two third connecting parts 314 at intervals along the first direction X and the two fourth connecting parts 315 at intervals along the first direction X, the two third connecting parts 314 can also be arranged in other directions (e.g., the second direction Y) and the two fourth connecting parts 315 can also be arranged in other directions (e.g., the second direction Y). However, this structure can only constrain the bracket 30 in the second direction Y and will reduce the opening length of the subsequent weight reduction hole 319.

[0125] Therefore, in this embodiment, the third connecting part 314 and the fourth connecting part 315 are designed to be arranged along the first direction X. After the bracket 30 is installed and connected to the battery box 10, the connection structure formed by the two third connecting parts 314 and the connection structure formed by the two third connecting parts 314 strokes constrain and fix the bracket 30 along the arrangement direction of the two connection structures. At the same time, the two third connecting parts 314 and the two fourth connecting parts 315 simultaneously constrain and fix the bracket 30 along the first direction X, which improves the stability of the bracket 30 after it is installed in the battery box 10.

[0126] In some examples, the third connection portion 314 may optionally include a first connection ear 3141 extending outward from the bracket body 31, the first connection ear 3141 having a first connection hole 3142 for docking with the battery housing 10; and / or, the fourth connection portion 315 includes a second connection ear 3151 extending outward from the bracket body 31, the second connection ear 3151 having a second connection hole 3152 for docking with the battery housing 10.

[0127] The first connecting lug 3141 is provided with a first connecting hole 3142 for docking with the battery housing 10. Correspondingly, a third connecting hole (not shown in the figure) that mates with the first connecting hole 3142 can be configured on the battery housing 10 (e.g., a beam).

[0128] Similarly, the second connecting ear 3151 is provided with a second connecting hole 3152 for docking with the battery housing 10. Correspondingly, a fourth connecting hole (not shown in the figure) that mates with the second connecting hole 3152 can be configured on the battery housing 10 (e.g., a beam).

[0129] The distance between the two first connecting holes 3142 of the two third connecting parts 314 is d, and the distance between the two second connecting holes 3152 of the two fourth connecting parts 315 is e. Correspondingly, the distance between the two third connecting holes is also d, and the distance between the two second connecting holes 3152 is also e.

[0130] Operators can observe the spacing of the above-mentioned connecting holes to determine the assembly direction of the bracket 30. In addition, after the first connecting hole 3142 and the third connecting hole are aligned, and after the second connecting hole 3152 and the fourth connecting hole are aligned, the first connecting ear 3141 and the second connecting ear 3151 can be fixedly installed on the battery box 10 by fasteners 34 such as bolts and screws. The structure is simple, easy to assemble, and can improve the stability of the bracket 30 after it is installed on the battery box 10.

[0131] In some examples, the third connection portion 314 optionally includes a first connection ear 3141 extending outward from the bracket body 31. The battery housing 10 has a first mounting surface 111 for connecting the first connection ear 3141. The first connection ear 3141 includes a first bent portion 31411 and a second bent portion 31412. One end of the first bent portion 31411 is connected to the bracket body 31. The first bent portion 31411 extends in a direction away from the electronic control assembly 40. The other end of the first bent portion 31411 is connected to the second bent portion 31412. The second bent portion 31412 is connected to the first bent portion 31411 at an angle, and the surface of the second bent portion 31412 facing the first mounting surface 111 contacts the first mounting surface 111.

[0132] The first bent portion 31411 and the second bent portion 31412 can be integrally connected to the bracket body 31 by welding or other means, or the bracket body 31, the first bent portion 31411 and the second bent portion 31412 can be integrally formed during processing, thereby improving the connection stability between the first connecting ear 3141 and the bracket body 31.

[0133] The structure of the second connecting ear 3151 in this embodiment is the same as or similar to that of the first connecting ear 3141, and will not be described in detail in this embodiment.

[0134] The first bent portion 31411 extends in the direction away from the electronic control component 40, so that the second bent portion 31412 is at a certain distance from the bracket body 31. This allows the bracket body 31 to form a certain distance from the battery box 10 after installation, giving the bracket body 31 a certain height, thereby facilitating heat dissipation of the bracket body 31 and the electronic control component 40.

[0135] The surface of the second bent portion 31412 facing the first mounting surface 111 is parallel to the first mounting surface 111 of the battery housing 10, which facilitates the first connecting ear 3141 to fit and connect with the battery housing 10.

[0136] Furthermore, the second bent portion 31412 in this embodiment can also be parallel to the bracket body 31. Specifically, the surface of the second bent portion 31412 along the third direction Z is parallel to the surface of the bracket body 31 along the third direction Z. This structure makes the bracket body 31 and the first mounting surface 111 parallel, so that the bracket body 31 can have a stable mounting surface to connect with the electronic control component 40 after assembly.

[0137] Combined again with the appendix Figure 5 As shown, in some examples, optionally, the bracket body 31 has a first protrusion 316 extending outward on at least one side along the first direction X. The first protrusion 316 has a fifth connecting part 317 and / or a sixth connecting part 318. The fifth connecting part 317 is used to fix the wire harness, and the sixth connecting part 318 is used to fix the conductive busbar.

[0138] The first protrusion 316 can extend to one side along the width direction of the bracket body 31, and the first protrusion 316 can be integrally formed with the bracket body 31 during processing.

[0139] The first protrusion 316 may be provided with one or both of the fifth connecting portion 317 and the sixth connecting portion 318. The fifth connecting portion 317 may be any structure capable of fixing the wire harness, such as a wire harness clamp or a wire harness groove. Similarly, the sixth connecting portion 318 may be any structure capable of fixing the conductor bar.

[0140] The wiring harness (not shown in the figure) can be the high-voltage wiring harness of the electronic control component 40 connecting to the high-voltage box inside the battery device 100, and the busbar (not shown in the figure) can be the output terminal of the battery device 100.

[0141] In this embodiment, the fifth connecting part 317 is used to facilitate the binding and fixing of the wire harness, reducing the possibility of wear between the bracket 30 and the wire harness, improving the performance stability of the wire harness, and optimizing the internal wiring of the battery device 100; the sixth connecting part 318 is used to bind and fix the conductive bar, reducing the possibility of wear between the bracket 30 and the conductive bar, and improving the position and structural stability of the conductive bar.

[0142] In some examples, the first extension 316 may optionally be provided with a fifth connection 317, which includes a first through hole 3171 and a first binding strap (not shown in the figure) passing through the first through hole 3171.

[0143] The number of first through holes 3171 can be two as shown in the figure. After the first binding strap passes through the two first through holes 3171, a closed loop structure is formed. The wire harness passes through the closed loop structure and is fixed. The first binding strap can adjust the size of the closed loop structure to accommodate wire harnesses of different specifications. Of course, the number of first through holes 3171 can also be one or more.

[0144] This embodiment uses a first binding strap passing through the first through hole 3171 to fix the wire harness. The structure is simple and different specifications of the first binding strap can be selected for wire harnesses of different specifications, which improves the versatility of the fifth connection part 317.

[0145] In some examples, the first extension 316 may optionally be provided with a sixth connecting portion 318, which includes a second through hole 3181 and a second binding strap (not shown in the figure) passing through the second through hole 3181.

[0146] The number of second through holes 3181 can be two. After the second binding strap passes through the two second through holes 3181, a closed loop structure is formed. The conductive busbar passes through the closed loop structure and is fixed. The second binding strap can adjust the size of the closed loop structure to accommodate conductive busbars of different specifications. Of course, the number of second through holes 3181 can also be one or more.

[0147] This embodiment uses a second binding strap passing through the second through hole 3181 to fix the wire harness. The structure is simple and different specifications of the second binding strap can be selected for different specifications of conductive busbars, which improves the universality of the sixth connection part 318.

[0148] In some examples, the first extension 316 may optionally include a third bend 3161 and a fourth bend 3162, the third bend 3161 extending away from the connection between the bracket body 31 and the battery box 10, the fourth bend 3162 being connected to the third bend 3161 at an angle, and the fourth bend 3162 extending away from the bracket body 31.

[0149] The connection point between the bracket body 31 and the battery box 10 is the location of the first connecting ear 3141 and the second connecting ear 3151.

[0150] The third bend 3161 extends away from the connection between the bracket body 31 and the battery box 10, allowing the fourth bend 3162 to form a distance along the third direction Z with the bracket body 31. After the bracket 30 is installed in the box, the fourth bend 3162, the third bend 3161 and the bracket body 31 form a clearance space, which facilitates the routing of wire harnesses and the placement of conductive bars.

[0151] Optionally, the fourth bend 3162 is connected at an angle to the third bend 3161 and is arranged parallel to the bracket body 31. The surface of the fourth bend 3162 is parallel to the surface of the bracket body 31, so that the side of the entire bracket 30 facing the electronic control component 40 has better flatness and consistency.

[0152] In some embodiments, the third bend portion 3161 is perpendicular to the bracket 30, and the fourth bend portion 3162 is perpendicular to the third bend portion 3161.

[0153] Combined again with the appendix Figure 5 As shown, in some examples, optionally, the bracket body 31 has a weight reduction hole 319, which faces the electronic control component 40.

[0154] The number of weight-reducing holes 319 can be one or more. The weight-reducing holes 319 can be opened in the middle, end or side of the bracket body 31, as long as they can achieve the weight-reducing effect.

[0155] The weight reduction hole 319 can reduce the weight and material consumption of the bracket body 31, save costs and increase the energy density of the battery device 100. Moreover, the weight reduction hole 319 facing the electronic control component 40 can improve the heat dissipation performance of the electronic control component 40.

[0156] In some examples, optionally, the length of the weight-reducing hole 319 is not less than half the length of the support body 31, and / or the width of the weight-reducing hole 319 is not less than half the width of the support body 31.

[0157] The length of the weight reduction hole 319 is greater than or equal to half the length of the bracket body 31, and the width of the weight reduction hole 319 is greater than or equal to half the width of the bracket body 31. This can improve the weight reduction effect, further reduce the weight and materials of the bracket body 31, thereby further improving the energy density of the battery device 100 and the heat dissipation performance of the electronic control component 40.

[0158] Although a larger weight-reducing hole 319 results in better weight reduction, an excessively large weight-reducing hole 319 will reduce the structural strength of the bracket body 31. Therefore, in some embodiments, the length of the weight-reducing hole 319 can be designed to be less than four-fifths of the length of the bracket body 31, and the width of the weight-reducing hole 319 can be designed to be less than four-fifths of the width of the bracket body 31. This satisfies the weight reduction requirements without compromising the structural strength of the bracket body 31 to support the electronic control component 40.

[0159] In some examples, optionally, the wall of the weight reduction hole 319 is recessed in the direction away from the electronic control assembly 40 to form a reinforcing rib 3191.

[0160] The wall of the weight-reducing hole 319 is recessed in the direction away from the electronic control component 40, which can be achieved by stamping process to form a reinforcing rib 3191, thereby improving the structural strength of the bracket body 31.

[0161] In addition, the reinforcing rib 3191 is formed by directly utilizing the stamping indentation of the hole wall of the weight reduction hole 319, which not only facilitates processing but also eliminates the need for additional consumables, thus reducing costs.

[0162] In some examples, the first anti-mistake part 313 may optionally include a fifth bending portion 3131 and a sixth bending portion 3132. The fifth bending portion 3131 extends in a direction away from the connection between the bracket body 31 and the battery box 10. The fifth bending portion 3131 and the sixth bending portion 3132 are connected at an angle, and the sixth bending portion 3132 extends in a direction away from the bracket body 31.

[0163] The fifth bend 3131 extends along the side away from the connection between the bracket body 31 and the battery box 10, so that the fifth bend 3131 has a certain stop height on the bracket body 31, thereby better blocking the wiring of the wiring terminal of the electronic control component 40, and achieving a better foolproof effect.

[0164] In this embodiment, the fifth bending portion 3131 and the sixth bending portion 3132 are connected at an angle, which can be an acute angle, an obtuse angle or a right angle.

[0165] Setting the sixth bend 3132 to extend away from the support body 31 can reduce the risk of injury caused by the abruptness of the fifth bend 3131.

[0166] Optionally, the sixth bend portion 3132 is connected at an angle to the fifth bend portion 3131 and is arranged parallel to the bracket body 31.

[0167] Combined with appendix Figure 7 As shown, in some examples, optionally, the first end 311 has a third connecting portion 314 on the side opposite to the electronic control assembly 40, which is connected to the battery housing 10; the second end 312 has a fourth connecting portion 315 on the side opposite to the electronic control assembly 40, which is connected to the battery housing 10; the bracket body 31 has a second anti-fooling portion 320 on the fourth connecting portion 315; the battery housing 10 has a first wall facing the first end 311 and a second wall facing the second end 312; the second wall is spaced apart from the second anti-fooling portion 320, or the second wall has a receiving space, and at least a portion of the second anti-fooling portion 320 is received in the receiving space.

[0168] For example, when the second anti-foolproof part 320 is provided, the distance d between two adjacent third connecting parts 314 and the distance e between two adjacent fourth connecting parts 315 can be Figure 7 The spacing d between the two third connecting parts 314 and the spacing e between the two adjacent fourth connecting parts 315 can be designed to be unequal (this embodiment is not shown in the figure).

[0169] The accommodating space can be located on the side wall or beam of the battery box 10, and this embodiment does not impose any restrictions on this. In this embodiment, blind holes or grooves can be provided on the second wall to form the accommodating space.

[0170] A second anti-misfit part 320 is provided on the fourth connecting part 315. When the bracket 30 tends to be installed backwards into the battery box 10, the second anti-misfit part 320 interferes with the first wall and cannot be assembled, thereby reducing the possibility that the bracket 30 is installed backwards into the box.

[0171] In some embodiments, the second anti-fooling part 320 may be a protruding structure, and the accommodating space may be formed by a structure such as an accommodating groove or a hole.

[0172] The protruding structure can be integrally formed with the first connecting ear 3141 or the second connecting ear 3151. When the bracket 30 tends to be installed backwards, the interference of the protruding structure and the second wall is used to prevent the bracket 30 from being installed backwards. The structure is simple and has a good anti-mistake effect.

[0173] It is understandable that there are two ways to reduce the possibility of the bracket 30 being installed backwards into the battery box 10. One is to use the second anti-mistake part 320 of this embodiment, and the other is to use the aforementioned spacing d and spacing e to be designed to be unequal. One of the above two methods can be chosen or both can coexist.

[0174] Secondly, embodiments of this application provide an electrical device including a battery device 100 according to any of the above technical solutions, wherein the battery device 100 is used to provide electrical energy or store electrical energy.
