[0053] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application.

Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0056] In the present application, unless otherwise specifically defined and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0057] In the battery device, the battery device is provided with a battery monomer assembly, a high-voltage power distribution device, and a battery management system and other modules. Among them, the high-voltage power distribution device is mainly to control the charging and discharging circuit of the battery device to proceed smoothly, which is responsible for controlling the power-on and power-off process, pre-charging process, and charging process of the high-voltage power circuit. The high-voltage power distribution device includes various electrical components, electrical connectors for realizing circuit connection, sampling components for collecting circuit signals, and connectors for transmitting electrical signals. For example, the electrical components include high-voltage relays, shunts, pre-charging relays, pre-charging resistors, and fuses. The electrical connectors include copper bars, aluminum bars, wire harnesses, etc. The sampling components include low-voltage sampling lines and sampling terminals. The connectors include low-voltage connectors and high-voltage connectors.

[0058] The main functions of the battery management system include data acquisition, state detection, safety protection, charging control, energy management, and balance management. It includes a master control unit, i.e., a battery management unit (BMU). The BMU includes a data acquisition circuit, a sensor, and a microcontroller (MCU) for processing collected data and communicating with other systems of the vehicle. In a distributed architecture, the battery management system can also include a slave control unit (CSC). The CSC is responsible for detecting a certain number of battery monomers or modules, collecting voltage, current, and temperature data, and sending this information to the BMU. The CSC mainly includes sensors for detecting battery monomers and data acquisition circuits.

[0059] In addition to electrical components (relays, fuses, pre-charging resistors, pre-charging relays, and current sensors), the high-voltage power distribution device also needs to reserve internal wire harness routing space. As a result, various wire harnesses need to occupy installation space, making it difficult for the high-voltage power distribution device as a whole to be miniaturized, ultimately affecting the overall grouping rate of the battery device.

[0060] Therefore, the present application provides an electric control device 100, which divides the wiring structure into a joint part and a connection part. At least part of the joint part and the connection part are accommodated in the shell to reduce the internal space occupied by the wiring structure in the shell. In this way, the internal space occupied by the wiring structure in the shell is reduced, making the overall volume of the shell more compact, and ultimately improving the grouping efficiency of the battery device.

[0061] Please refer to Figures 3 to 8 , in a first aspect, the present application provides an electric control device 100, comprising a shell 10 and a wiring structure 20.

[0062] The wiring structure 20 comprises at least two joint portions 21 and connecting portions 22 connected to the joint portions 21; wherein, in the height direction of the shell 10, the projections of the joint portions 21 do not coincide, and the joint portions 21 and the connecting portions 22 are at least partially accommodated in the shell 10.

[0063] It can be understood that the shell 10 is the main part of the electric control device 100, used to support and fix various devices, that is, the shell 10 is a bearing structure. The shell 10 should have a containing space for installing various electrical components.

[0064] The wiring structure 20 refers to the line structure for realizing the electrical connection between various electrical components in the electric control device 100 and the battery management unit, the slave control unit and the battery device. Therefore, the wiring structure 20 can be a sampling line for realizing the electrical connection between the battery management unit and the electrical components, so as to collect low-voltage signals and high-voltage signals of the electrical components by using the sampling line. The wiring structure 20 can also be a high-voltage bar for realizing the electrical connection between the battery device and the electrical components.

[0065] Among them, the joint portion 21 is the joint end of the wiring structure 20 connected to the connection position of the electrical components, the battery management unit and the slave control unit. Of course, according to different connection objects, the shape structure of the joint portion 21 will also be adjusted accordingly. For example, the joint portion 21 can be a flat copper bar, a plug joint, etc. The connecting portion 22 is the line body part for connecting the joint portions 21. Here, the connection mode of the connecting portion 22 and the joint portions 21 includes but is not limited to welding, threaded connection, plug-in, clamping and one-piece forming, etc.

[0066] Since the wiring structure 20 should occupy the internal space of the shell 10, directly arranging the wiring structure 20 in the internal space of the shell 10 will compress the installation space of other electrical components, or the overall volume of the shell 10 needs to be larger. Therefore, the joint portions 21 and the connecting portions 22 of the wiring structure 20 are at least partially accommodated in the shell 10, that is, they are fixed in the internal space of the shell 10 in an embedded manner, so as to improve the problem of the wiring structure 20 occupying the internal space of the shell 10.

[0067] In the height direction of the shell 10, the projections of the joint portions 21 do not coincide, which means that the wiring structure 20 is laid in the shell 10, rather than being accommodated in the shell 10 in a penetrating manner in the height direction of the shell 10.

[0068] Here, the joint portions 21 and the connecting portions 22 can be integrally injection molded with the shell 10, or the inner wall surface of the shell 10 can be recessed to form a groove structure, and then the joint portions 21 and the connecting portions 22 are limited in the groove structure.

[0069] Exemplarily, the shell 10 is generally made of plastic material and is formed by injection molding, so that each joint part 21 and the connecting part 22 can be placed in a mold for forming the shell 10, and the shell 10 and the joint part 21 and the connecting part 22 are formed by in-mold injection. The advantage of this mode is that the stability of the fixed limiting of the wiring structure 20 is higher, especially for some vibration or shaking use scenarios.

[0070] Exemplarily, a groove structure is formed on the inner wall or the outer wall surface of the shell 10, and then each joint part 21 and the connecting part 22 are placed in the groove structure, and then some limiting and fixing structures are used to limit the joint part 21 and the connecting part 22. The advantage of this mode is that according to the detachability of the limiting and fixing structure, the position of the wiring structure 20 in the groove structure can be adjusted or taken out and placed again, which is more suitable for later maintenance of the wiring structure 20.

[0071] The electric control device 100 of the utility model, wherein the wiring structure 20 includes at least two joint parts 21 and the connecting part 22 connecting the joint parts 21, and the projection of each joint part 21 does not coincide in the height direction of the shell 10, wherein each joint part 21 and the connecting part 22 are at least partially accommodated in the shell 10. In this way, at least part of the wiring structure 20 is accommodated in the shell 10, thereby reducing the internal space of the shell 10 occupied by the wiring structure 20, so that the overall volume of the shell 10 can be designed more compactly, and finally the grouping efficiency of the battery device is improved.

[0072] Please refer to Figure 4 In some embodiments, the connecting part 22 is integrally formed in the shell 10, and / or the joint part 21 is integrally formed in the shell 10.

[0073] It can be understood that according to the arrangement position of the wiring structure 20 in the shell 10, the connecting part 22 of the wiring structure 20 can be integrally formed in the shell 10, or the joint part 21 of the wiring structure 20 can be integrally formed in the shell 10, or both the connecting part 22 and the joint part 21 can be integrally formed in the shell 10.

[0074] Here, the integrally formed mode is to place the joint part 21 and / or the connecting part 22 of the wiring structure 20 in a forming mold, and then integrally extrude and form.

[0075] In this way, according to the actual use requirements, only the connecting part 22, only the joint part 21, and the connecting part 22 and the joint part 21 integrally formed in the shell 10 are selected, thereby saving the internal space of the shell 10.

[0076] Please refer to Figure 4In some embodiments, the housing 10 is provided with a positioning hole 11a for accommodating a positioning structure for positioning the connecting portion 22 and / or the joint portion 21.

[0077] It can be understood that when the joint portion 21 and / or the connecting portion 22 of the wiring structure 20 is positioned in the molding die, the joint portion 21 and / or the connecting portion 22 is not positioned by an additional positioning structure in the molding die due to cost considerations. Therefore, during the injection molding process, the joint portion 21 and / or the connecting portion 22 is easily offset by the filler.

[0078] In order to solve the above problem, an additional positioning structure outside the molding die of the housing 10 is added to position the joint portion 21 and / or the connecting portion 22. After the injection molding of the housing 10 is completed, the positioning structure is separated from the housing 10 by means of core pulling. Therefore, the positioning hole 11a is formed on the housing 10.

[0079] Here, according to the shape structure and volume size of the joint portion 21 and the connecting portion 22, the positioning structure can be a columnar structure, a needle-like structure, or a combination of the two.

[0080] In this way, the positioning hole 11a on the housing 10 is used to provide the positioning structure, which is used to position the connecting portion 22 and / or the joint portion 21 of the in-mold injection molding, so as to reduce the change in position of the connecting portion 22 and / or the joint portion 21 relative to the housing 10 during the injection molding process.

[0081] Please refer to Figure 5 In some embodiments, a receiving groove 11b is formed on the surface of the housing 10, and the connecting portion 22 and the joint portion 21 are at least partially accommodated in the receiving groove 11b.

[0082] It can be understood that the receiving groove 11b is a groove structure formed by recessing inward from the surface of the housing 10. The structure type of the receiving groove 11b can be a single-sided opening groove structure formed by recessing from one side surface of the housing 10. Alternatively, the receiving groove 11b can also be a double-sided opening groove structure formed by recessing from opposite side surfaces of the housing 10. In addition, the double-sided opening groove structure can also be partially or fully connected according to actual use requirements. That is, if it is partially connected, a through hole is formed on the groove bottom wall of the groove structure. If it is fully connected, the groove bottom wall of the groove structure is completely removed. At this time, the receiving groove 11b is a through groove of the housing 10.

[0083] According to actual use requirements, at least part of the connecting portion 22 and the joint portion 21 is accommodated in the receiving groove 11b. For example, all of the connecting portion 22 and part of the joint portion 21 can be accommodated in the receiving groove 11b. Alternatively, all of the connecting portion 22 and all of the joint portion 21 can be accommodated in the receiving groove 11b.

[0084] Thus, the connection portion 22 and the joint portion 21 are accommodated in the accommodation groove 11b, so as to reduce the wire exposed in the accommodation space of the shell 10.

[0085] Please refer to Figure 6 and Figure 7 In some embodiments, the shell 10 comprises a limiting structure for limiting the connection portion 22 and the joint portion 21 in the accommodation groove 11b.

[0086] It can be understood that the joint portion 21 and the connection portion 22 placed in the accommodation groove 11b have connection stability, that is, the joint portion 21 and the connection portion 22 are difficult to be fixed and limited in the accommodation groove 11b, so that the limiting structure is needed to limit and fix the connection portion 22 and the joint portion 21 in the accommodation groove 11b.

[0087] The limiting structure can be externally arranged at the accommodation groove 11b, for example, the limiting structure can be glue, glue block and combination of the two; or the limiting structure can also be integrally formed and arranged in the accommodation groove 11b, for example, the limiting structure is a limiting protruding column, a limiting groove or a limiting buckle formed on the groove wall of the accommodation groove 11b.

[0088] For example, the accommodation groove 11b is arranged at the shell 10, the joint portion 21 and the connection portion 22 of the wire structure 20 are placed in the accommodation groove 11b, and then the glue is filled in the accommodation groove 11b to limit and fix the joint portion 21 and the connection portion 22.

[0089] For example, the non-through accommodation groove 11b is arranged at the shell 10, and the limiting buckle is arranged at the groove wall of the accommodation groove 11b, the joint portion 21 and the connection portion 22 are placed in the accommodation groove 11b, and then clamped at the limiting buckle.

[0090] Thus, the limiting structure is used to limit the connection portion 22 and the joint portion 21 placed in the accommodation groove 11b, so that the connection portion 22 and the joint portion 21 are maintained in the accommodation groove 11b.

[0091] Please refer to Figure 6 and Figure 7 In some embodiments, the limiting structure comprises the glue 11c1 filled in the accommodation groove 11b; or,

[0092] The limiting structure comprises the buckle member 11c2 arranged in the accommodation groove 11b and used for clamping the connection portion 22 and the joint portion 21.

[0093] It can be understood that the colloid 11c1 is a filling body arranged independently from the shell 10, and the colloid 11c1 has a certain fluidity before filling the accommodating groove 11b, and gradually loses fluidity and fills in the accommodating groove 11b after filling is completed. The buckle member 11c2 is a clamping structure that can be formed integrally on the groove wall of the accommodating groove 11b, or a clamping structure that can be fixed on the groove wall of the accommodating groove 11b through an additional connecting structure.

[0094] In this way, by filling the colloid 11c1 in the accommodating groove 11b, or by clamping the buckle member 11c2 on the connecting portion 22 and the joint portion 21, the connecting portion 22 and the joint portion 21 are limited in the accommodating groove 11b.

[0095] In some embodiments, at least one joint portion 21 is welded to the connecting portion 22; or,

[0096] At least one joint portion 21 is screwed to the connecting portion 22; or,

[0097] At least one joint portion 21 is integrally formed with the connecting portion 22.

[0098] It can be understood that the connection mode of the joint portion 21 and the connecting portion 22 includes but is not limited to welding connection, threaded connection and integral forming connection.

[0099] Here, the welding connection can be ultrasonic welding or resistance welding. And holes are arranged on the joint portion 21 and the connecting portion 22, and a fastener is arranged through the holes to realize the connection. Furthermore, the joint portion 21 and the connecting portion 22 are extruded or cast together.

[0100] In this way, the joint portion 21 can be connected to the connecting portion 22 by welding, threaded connection and integral forming connection.

[0101] Please refer to Figure 8 In some embodiments, the connecting portion 22 has a flat connecting end 22a connected to the joint portion 21.

[0102] It can be understood that the connecting end 22a is the end of the connecting portion 22 connected to the joint portion 21, and the flat connecting end 22a means that the thickness is thin and the contact area with the joint portion 21 is larger.

[0103] Here, the flat connection can be understood as forming a flat surface towards the surface of the joint portion 21 of the connecting end 22a, or pressing the entire connecting end 22a to form a flat structure, so that the connecting end 22a has two relatively arranged surfaces in flat state.

[0104] In this way, the flat connection end 22a has a larger contact area with the joint portion 21, and is more suitable for welding connection between the connection portion 22 and the joint portion 21 by ultrasonic welding or resistance welding.

[0105] In some embodiments, the surface of the joint portion 21 is formed with a passivation layer (not shown in the figure).

[0106] It can be understood that the passivation layer is used to improve the corrosion resistance of the joint portion 21. Since the joint portion 21 needs to be connected with the electrical components, the connection positions of the battery management monomer, and the connection positions of the slave control unit, the joint portion 21 is most likely to be exposed to the shell 10. Therefore, the corrosion resistance of the joint portion 21 needs to be improved by setting the passivation layer.

[0107] Here, the passivation layer can be formed on the entire surface or part of the surface of the joint portion 21, and the thickness of the passivation layer can be adjusted according to the specific use scenario. Generally, the thickness of the passivation layer is several nanometers to tens of nanometers. Especially when the joint portion 21 is formed by injection molding with the shell 10, using the traditional tin plating method, the high-temperature molten injection material will melt the tin layer, and the protection function cannot be achieved.

[0108] In this way, the surface of the joint portion 21 is passivated to form a passivation layer to avoid the problem of tin melting caused by tin plating when the wiring structure 20 and the shell 10 are formed by injection molding.

[0109] Please refer to Figure 3 In some embodiments, the shell 10 includes a top cover 11 and a base 12 surrounding the top cover 11 to form a containing space. The electrical control device 100 includes electrical components 30 arranged in the containing space and a battery management master control board 40 electrically connected with the electrical components 30.

[0110] The wiring structure 20 includes a sampling line. At least part of the sampling line is arranged in the top cover 11. Part of the joint portion 21 of the sampling line is connected with the connection position of the electrical components 30. The remaining joint portion 21 of the sampling line is connected with the connection position of the battery management master control board 40.

[0111] It can be understood that in order to install the electrical components 30 and / or the battery management master control board 40, the shell 10 is divided into the top cover 11 and the base 12 which is connected with the top cover 11. The base 12 is the base of the shell 10, which is used to carry the electrical components 30 and the battery management master control board 40. The top cover 11 is a cover plate structure which is combined with the base 12 to form a containing space. In terms of the arrangement of the wiring structure 20, the wiring structure 20 can be arranged in the top cover 11, the base 12, or the top cover 11 and the base 12.

[0112] The sampling line is a wire harness for collecting low-voltage signals and high-voltage signals of the electrical component 30. Therefore, some of the joint portions 21 of the sampling line are connected to the connection positions of the electrical component 30, and the remaining joint portions 21 are connected to the connection positions of the battery management main control board 40.

[0113] In this way, by connecting some of the joint portions 21 of the sampling line to the connection positions of the electrical component 30 and connecting the remaining joint portions 21 to the connection positions of the battery management main control board 40, the efficiency of connecting the sampling line to the electrical component 30 and the battery management main control board 40 is improved.
