Description

Technical Field

[0001] This disclosure relates to the field of high-voltage distribution box manufacturing technology, and in particular to a high-voltage distribution box, battery and power-consuming device. Background Technology

[0002] Before the high-voltage distribution box is completed, electrical components such as fuses are only locked to the first end. The conventional solution for the second end is to use cable ties to pass through the fuse mounting holes and the high-voltage box inserts to bind and fix it to the high-voltage box shell.

[0003] Because electrical components such as fuses are only locked at one end and the other end is not locked, the locked end of the fuse or other electrical components may loosen or fall off due to bumps and vibrations during transportation, and the unlocked end may also be bumped, resulting in a decrease in fit or being scratched by the belt. Utility Model Content

[0004] Embodiments of this disclosure provide a high-voltage distribution box, a battery, and an electrical device that can protect electrical components.

[0005] According to a first aspect of this disclosure, a high-voltage distribution box is provided, comprising a mounting housing, electrical components, and an electrical component protection device.

[0006] Cover; and

[0007] A snap-fit ​​assembly is attached to the side of the cover and is configured to be detachably attached to the mounting housing to press the electrical connection between the cover and the mounting housing in the connected state.

[0008] The high-voltage distribution box of this embodiment uses a snap-fit ​​assembly to press the electrical connection parts between the cover and the mounting shell, which can fix the non-locking ends of electrical components, prevent the fasteners 4 of the locking ends of electrical components from loosening and twisting, and improve the overall safety of electrical components; it can protect electrical components and their electrical connection parts, ensuring that the flatness and surface treatment of the electrical connection parts are not damaged; the snap-fit ​​assembly ensures accurate fixing position of the cover, improves the consistency of pre-tightening force, and reduces the assembly difficulty for assembly personnel; the electrical component protection device can be recycled and reused after removal, which can avoid resource waste; the high-voltage distribution box can improve the safety of the high-voltage distribution box by protecting the electrical connection parts during transportation through the electrical component protection device.

[0009] In some embodiments, the snap-fit ​​assembly includes a snap-fit ​​unit, which includes a connecting portion and a claw portion. The connecting portion is connected between the cover and the claw portion, and the claw portion is used to detachably engage with a slot on the outer wall of the mounting housing.

[0010] In this embodiment, the claw portion can be detachably engaged with the slot on the outer wall of the mounting housing, enabling convenient and quick assembly and disassembly of the electrical component protection device; by flexibly adjusting the distance between the cover and the slot during the design, the designed electrical component protection device can be matched with the required preload of the electrical connection portion.

[0011] In some embodiments, the connecting portion is fixedly connected to the cover, and the extending direction of the connecting portion is perpendicular to the plane of the cover.

[0012] This embodiment uses a snap-fit ​​design where the connecting part is fixedly connected to the cover, and the connecting part is rotatably connected to the cover. This further simplifies the structure of the electrical component protection device and improves its stability and service life.

[0013] In some embodiments, a protrusion is provided on the outer side of the connector.

[0015] In some embodiments, the snap-fit ​​assembly includes two snap-fit ​​units respectively disposed on both sides of the cover along a first direction.

[0016] The buckle assembly of this embodiment includes two buckle units respectively disposed on both sides of the cover along the first direction, which can apply pre-tightening force from both sides of the cover to improve the stability of the electrical component protection device after installation and further protect the electrical components.

[0017] In some embodiments, multiple sets of snap-fit ​​components are spaced apart along a second direction, which is perpendicular to the first direction.

[0018] In this embodiment, multiple sets of snap-fit ​​components are spaced apart along the second direction, which enables pre-tightening force to be applied to multiple points on the same side of the cover, further improving the stability of the electrical component protection device after installation.

[0019] In some embodiments, the latching assembly further includes a latching unit disposed on one side of the cover along a second direction, the second direction being perpendicular to the first direction.

[0020] The latching assembly of this embodiment also includes a latching unit disposed on one side of the cover along the second direction, which can cooperate with the latching units disposed on both sides of the cover along the first direction, so as to achieve a more stable and reliable latching of the latching assembly on multiple sides of the cover, while also structurally avoiding the main body of the electrical components.

[0021] In some embodiments, the electrical component protection device further includes:

[0022] An elastic partition is provided on the side of the cover facing the electrical connection part.

[0023] This embodiment provides an elastic partition on the side of the cover facing the electrical connection portion, which presses the electrical component tightly. This prevents the cover from damaging the surface of the electrical component during the pressing process, thereby improving the protection of the electrical component by the electrical component protection device.

[0024] In some embodiments, multiple electrical component protection devices are provided, each with a different thickness of its elastic partition. The high-voltage distribution box may selectively install electrical component protection devices that are adapted to the required preload of the electrical connection.

[0025] The high-voltage distribution box of this embodiment selects an appropriate electrical component protection device according to the required pre-tightening force of the electrical connection part, which can balance the elastic force of the elastic partition and the clamping force of the cover, effectively clamping the electrical connection part and protecting the contact surface of the electrical connection part, as well as protecting the electrical components.

[0026] In some embodiments, the cover, snap-fit ​​assembly, and resilient partition are integrally formed.

[0027] In this embodiment, the cover, snap-fit ​​assembly, and elastic partition are integrally formed, for example, by injection molding material being cast into the elastic partition as an integral structure, which allows for integrated material supply, simplifies the production process, and reduces production costs.

[0028] In some embodiments, the cover and the elastic partition are provided with through holes extending along the thickness direction.

[0029] The through-hole in this embodiment can avoid stud-shaped inserts, allowing electrical component protection devices to be installed in shunts, etc.

[0030] In some embodiments, the edges of the cover and / or the snap-fit ​​assembly are chamfered.

[0031] The edges of the cover and / or the snap fastener assembly in this embodiment are chamfered to prevent the edges from bumping and damaging electrical components, and to prevent damage to other electrical components that are not equipped with electrical component protection devices.

[0032] In some embodiments, the electrical components include at least one of a fuse, a shunt, and a copper busbar.

[0033] The high-voltage distribution box in this embodiment can protect various electrical components such as fuses, shunts, and copper busbars, thereby improving the overall production quality of the high-voltage distribution box.

[0047] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the present disclosure or its application or use. The present disclosure may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that the present disclosure will be thorough and complete, and will fully express the scope of the disclosure to those skilled in the art. It should be noted that, unless specifically stated otherwise, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0048] The terms "first," "second," and similar words used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "contains" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, this relative positional relationship may also change accordingly.

[0049] In this disclosure, when a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may be not directly connected to the other devices but have an intermediary device.

[0050] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0051] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0052] Based on the embodiments disclosed above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0053] In the production process of high-voltage distribution boxes in related technologies, the process from design and preliminary assembly to packaging requires the cooperation of multiple parties. Before the high-voltage distribution box is completed, there is a need for transportation, such as from preliminary assembly to packaging. During this process, it is necessary to lock the first end of the electrical components and use cable ties to pass through the mounting holes of electrical components such as fuses and the inserts of the lower shell of the high-voltage box to bind and fix the second end of the electrical components to the high-voltage box shell.

[0054] Because electrical components such as fuses are only secured at one end, and the other end is not secured, the secured end of the fuse may loosen or fall off due to bumps and vibrations during transportation, and the unsecured end may also be bumped, resulting in a decrease in fit. After delivery, the cable ties need to be cut off, which will increase the workload and waste materials. The cable ties pass through the mounting holes and inserts of electrical components such as fuses, which may scratch the mounting holes and inserts of electrical components such as fuses. At the same time, the assembly personnel cannot accurately control the position and binding force of the cable ties.

[0055] Based on the above problems, firstly, this disclosure proposes a high-voltage distribution box, such as... Figures 1 to 6 As shown, the high-voltage distribution box includes a mounting housing 100, electrical components 200, and an electrical component protection device 300. The electrical component 200 includes a main body 202 and an electrical connection portion 201 connected to one side of the main body 202. The electrical connection portion 201 is disposed inside the mounting housing 100. The electrical component protection device 300 includes:

[0056] Cover 1; and

[0057] The snap-fit ​​assembly 2 is connected to the side of the cover 1. The snap-fit ​​assembly 2 is configured to be detachably connected to the mounting housing 100 so as to press the electrical connection part 201 between the cover 1 and the mounting housing 100 in the connected state.

[0058] Specifically, the cover 1 and the snap-fit ​​assembly 2 are fixedly connected by the snap-fit ​​assembly 2, which is convenient to install and remove, accurate in fixing position, and easy to control the pre-tightening force; pressing the electrical connection part 201 between the cover 1 and the mounting shell 100 can ensure that the electrical connection part 201 will not be damaged; the electrical component protection device 300 can be recycled and reused after being removed, which can avoid resource waste.

[0059] Specifically, the high-voltage distribution box includes a housing 400, within which are provided multiple mounting shells 100 for mounting the electrical connection portions 201 of various electrical components 200. The electrical components 200 may include locked and unlocked ends. The locked ends are fixed to the housing 400 of the high-voltage distribution box by fasteners, while the unlocked ends are pressed between the cover 1 and the housing 400 by an electrical component protection device 300, thereby protecting the electrical components 200. The housing 400 is the lower housing of the high-voltage distribution box.

[0060] Optionally, the snap-fit ​​assembly 2 is connected to the side of the cover 1 along the first direction x or the second direction y, and the electrical connection part 201 is connected to the side of the main body part 202 along the second direction y, where the second direction y is perpendicular to the first direction x.

[0061] For example, the electrical component 200 may include a fuse. The main body 202 of the fuse is provided with an electrical connection portion 201 on each side along the second direction y. The main body 202 is a column with its central axis extending along the second direction y. The electrical connection portion 201 includes a mounting hole 105, which may be an elongated hole. A high-voltage box insert 106 is provided below the electrical connection portion 201. By installing the electrical component protection device 300, the electrical connection portion 201 is pressed between the cover 1 and the mounting shell 100, which can protect the entire fuse and the high-voltage box insert 106 from damage at the non-locking end of the electrical component 200.

[0062] Optionally, the size and shape of the cover 1 can be customized as needed, and the specific position of the latching assembly 2 on the side of the cover 1 can be customized as needed. The needs may include the size, shape, position, or space required for electrical components, or the location of the slot on the outer wall of the mounting housing 100. Optionally, the plane containing the cover 1 can be perpendicular to a third direction z. Optionally, the latching assembly 2 may include one or more identical or different latching units, and one or more sets of latching assemblies 2 can be provided. Optionally, the latching assembly 2 can adopt any latching form.

[0063] In this embodiment, the high-voltage distribution box uses a snap-fit ​​assembly 2 to press the electrical connection part 201 between the cover 1 and the mounting shell 100, which can fix the non-locking end of the electrical component 200, prevent the fastener 104 of the locking end of the electrical component from loosening, and improve the overall safety of the electrical component 200; it can protect the electrical component 200 and its electrical connection part 201, ensuring that the flatness and surface treatment of the electrical connection part 201 are not damaged; the snap-fit ​​assembly 2 ensures that the fixing position of the cover 1 is accurate, which can improve the consistency of the pre-tightening force and reduce the assembly difficulty for assembly personnel; the electrical component protection device can be recycled and reused after removal, which can avoid resource waste; during the transportation of the high-voltage distribution box, the electrical connection part 201 is protected by the electrical component protection device 300, which can improve the safety of the high-voltage distribution box.

[0064] In some embodiments, such as Figures 1 to 6 As shown, the buckle assembly 2 includes a buckle unit 20, which includes a connecting part 21 and a claw part 22. The connecting part 21 is connected between the cover 1 and the claw part 22, and the claw part 22 is used to detachably engage with the slot 103 on the outer wall of the mounting shell 100.

[0065] Specifically, the positions of the connecting part 21 and the claw part 22 are relatively fixed. When the claw part 22 is engaged with the slot 103, the positions of the cover 1, the connecting part 21, the claw part 22, and the slot 103 are relatively fixed. Specifically, the position of the slot 103 on the outer wall of the mounting shell 100 is adapted to the position of the slot 103.

[0066] Optionally, when the claw portion 22 disengages from the slot 103, the position of the connecting portion 21 relative to the cover 1 can be fixed or movable; for example, the connecting portion 21 can be rotatable relative to the cover 1. Optionally, one or more latching units 20 can be provided. Optionally, the distance between the cover 1 and the slot 103 can be designed according to the preload requirements; for example, the length of the connecting portion 21 or the size of the claw portion 22 can be adjusted during the design phase.

[0067] In this embodiment, the claw portion 22 is detachably engaged with the slot 103 on the outer wall of the mounting housing 100, which enables convenient and quick assembly and disassembly of the electrical component protection device 300. By flexibly adjusting the distance between the cover 1 and the slot 103 during the design, the designed electrical component protection device 300 can be matched with the required preload of the electrical connection portion 201.

[0068] In some embodiments, such as Figures 1 to 4 As shown, the connecting part 21 is fixedly connected to the cover 1, and the extending direction of the connecting part 21 is perpendicular to the plane of the cover 1.

[0069] Optionally, the connecting portion 21 can extend along a third direction z, which is perpendicular to the first direction x and the second direction y. Optionally, the snap-fit ​​unit 20 can be integrally formed with the cover 1 by injection molding or other methods, which is cost-effective.

[0070] This embodiment uses a snap-fit ​​design where the connecting part 21 is fixedly connected to the cover 1, and the connecting part 21 is rotatably connected to the cover 1. This design further simplifies the structure of the electrical component protection device and improves its stability and service life.

[0071] In some embodiments, such as Figures 1 to 4 As shown, a protrusion 23 is provided on the outer side of the connecting part 21.

[0072] Specifically, the snap-fit ​​assembly 2 is flexible to facilitate disassembly and assembly via the protrusion 23.

[0073] The protrusion 23 in this embodiment can serve as a handle for installing and removing the electrical component protection device 300, reducing the difficulty of installation and removal, increasing the speed of installation and removal for operators, and thus improving production efficiency.

[0074] In some embodiments, such as Figures 1 to 4 As shown, the buckle assembly 2 includes two buckle units 20 respectively disposed on both sides of the cover 1 along the first direction x.

[0075] Optionally, the snap fastener 2 can be set in one or more groups along the second direction y. The multiple groups of snap fastener 2 can be set adjacent to each other or spaced apart.

[0076] The buckle assembly 2 in this embodiment includes two buckle units 20 respectively disposed on both sides of the cover 1 along the first direction x, which can apply pre-tightening force from both sides of the cover 1 to improve the stability of the electrical component protection device 300 after installation and further protect the electrical component 200.

[0077] In some embodiments, such as Figure 1 As shown, multiple sets of buckle components 2 are arranged at intervals along the second direction y, and the second direction y is perpendicular to the first direction x.

[0078] In this embodiment, multiple sets of buckle components 2 are arranged at intervals along the second direction y, which enables multiple points on the same side of the cover 1 to be pre-tightened, thereby further improving the stability of the electrical component protection device after installation.

[0079] In some embodiments, such as Figure 4 As shown, the buckle assembly 2 also includes a buckle unit 20 disposed on one side of the cover 1 along the second direction y, the second direction y being perpendicular to the first direction x.

[0080] Specifically, the snap-fit ​​unit 20, which is positioned along the second direction y, is located on the side away from the main body 202 in the installed state.

[0081] The latching assembly 2 in this embodiment also includes a latching unit 20 disposed on one side of the cover 1 along the second direction y, which can cooperate with the latching units 20 disposed on both sides of the cover 1 along the first direction x, so as to achieve a more stable and reliable latching of the latching assembly 2 on multiple sides of the cover 1, while also structurally avoiding the main body 202 of the electrical component 200.

[0082] In some embodiments, such as Figures 1 to 4 As shown, the electrical component protection device also includes:

[0083] An elastic partition 11 is provided on the side of the cover 1 facing the electrical connection portion 201.

[0084] Optionally, the elastic partition 11 may be made of an elastic material such as foam.

[0085] This embodiment provides an elastic partition 11 on the side of the cover 1 facing the electrical connection portion 201, so that the elastic partition 11 presses against the electrical component. This prevents the cover 1 from damaging the surface of the electrical component during the pressing process, thereby improving the protection of the electrical component by the electrical component protection device.

[0086] In some embodiments, multiple electrical component protection devices 300 are provided, and the thickness of the elastic partition 11 of each electrical component protection device 300 is different along the third direction z. The high-voltage distribution box can selectively install electrical component protection devices that are adapted to the required preload of the electrical connection part 201. The third direction z is perpendicular to the first direction x and the second direction y.

[0087] The high-voltage distribution box of this embodiment selects an electrical component protection device 300 that is compatible with the pre-tightening force required by the electrical connection part 201. This enables the elastic force of the elastic partition 11 to be balanced with the clamping force of the cover 1, which can effectively clamp the electrical connection part 201, protect the contact surface of the electrical connection part 201, and protect the electrical component 200.

[0088] In some embodiments, the cover 1, the snap-fit ​​assembly 2, and the elastic partition 11 are integrally formed.

[0089] Alternatively, the electrical component protection device may be integrally molded from an elastic element and a plastic cover.

[0090] In this embodiment, the cover 1, the buckle assembly 2, and the elastic partition 11 are integrally formed. For example, the injection molding material is cast into the elastic partition 11 to form an integral structure, which can be supplied as a whole, simplifying the production process and reducing production costs.

[0091] In some embodiments, such as Figure 4 As shown, the cover 1 and the elastic partition 11 are provided with through holes 10 that extend through the thickness direction.

[0092] Specifically, the thickness direction is the height direction, or the third direction z, which is perpendicular to the first direction x and the second direction y.

[0093] The through hole 10 in this embodiment can avoid the stud-shaped insert, so that the electrical component protection device can be installed in the shunt, etc.

[0094] In some embodiments, such as Figures 1 to 4 As shown, the edges of the cover 1 and / or the snap fastener assembly 2 are chamfered.

[0095] The edges of the cover 1 and / or the buckle assembly 2 in this embodiment are chamfered to prevent the edges from bumping and damaging electrical components, and to prevent damage to other electrical components that are not equipped with electrical component protection devices.

[0096] In some embodiments, electrical component 200 includes at least one of a fuse, a shunt, and a copper busbar. The copper busbar is also known as a copper bar.

[0097] The high-voltage distribution box in this embodiment can protect various electrical components 200 such as fuses, shunts and copper busbars, thereby improving the overall production quality of the high-voltage distribution box.

[0098] In some specific embodiments, such as Figure 5 As shown, the electrical component 200 includes a fuse, and the electrical connection portion 201 of the fuse includes a mounting hole 105. A high-voltage box insert 106 is provided below the electrical connection portion 201. Compared with the cable tie fixing method in related technologies, by installing the electrical component protection device 300, the electrical connection portion 201 can be pressed between the cover 1 and the mounting shell 100 of the housing 400. This can protect the mounting hole 105 and the high-voltage box insert 106 from damage at the non-locking end of the fuse, and at the same time prevent the fastener 104 at the locking end of the fuse from untwisting, thereby improving the safety of the main body 202.

[0099] Secondly, this disclosure also proposes a battery including the high-voltage distribution box described in the above embodiments.

[0100] Specifically, the high-voltage distribution box is located inside the battery, for example, near the interface inside the battery.

[0101] In this embodiment, the high-voltage distribution box of the battery protects the electrical component 200 through the electrical component protection device 300. The electrical component 200 has high overall safety, and the flatness and surface treatment of the electrical connection part 201 are not damaged. The high-voltage distribution box has low assembly difficulty and high stability, which can reduce the assembly difficulty of the battery and improve the stability and safety of the battery.

[0102] In addition, this disclosure also proposes an electrical device, including the high-voltage distribution box of the above embodiments, or the battery of the above embodiments.

[0103] Optionally, the high-voltage distribution box can be located inside or outside the battery to enable rapid battery replacement, for example, in electrical devices such as electric vehicles.

[0104] In this embodiment, the high-voltage distribution box of the electrical device protects the electrical component 200 through the electrical component protection device 300. The electrical component 200 has high overall safety, and the flatness and surface treatment of the electrical connection part 201 are not damaged. The high-voltage distribution box has low assembly difficulty and high stability, which can reduce the assembly difficulty of the electrical device and improve the stability and safety of the electrical device.
