Background Technology

[0002] Generally, vehicles are equipped with various electrical devices for the operation of the vehicle itself and the convenience of the passengers; these devices are electrically connected to batteries and generators to receive the power necessary for operation, and are operated by the driver's switch operation and the electronic control of a controller.

[0003] In addition, fuses are provided on the power supply lines of electrical devices to protect them by causing a short circuit when excessive current flows due to an abnormality or overload in the electrical system, and they are installed collectively in a fuse box for the convenience of management.

[0004] Meanwhile, for electric vehicles equipped with high-voltage batteries, the fuse box housing the high-voltage battery fuse must be designed considering optimal size to reduce cost and weight, a minimum opening that facilitates easy fuse replacement in the event of failure while enhancing watertightness, rigidity against external impacts, electromagnetic shielding, and ease of internal battery workability.

[0005] In particular, Korean Registered Patent Publication No. 10-2086128 (Registration Date: March 2, 2020) discloses "a battery pack and an electric vehicle including said battery pack," and Korean Published Patent Publication No. 10-2020-0080068 (Publication Date: July 6, 2020) discloses "a battery module, a battery pack including said battery module and an automobile including said battery pack."

[0006] The technical configuration described above is provided as background technology to aid in understanding the present invention and does not constitute prior art widely known in the technical field to which the present invention belongs. The problem to be solved

[0007] A fuse box connected to a vehicle battery pack according to conventional technology has the problem of increased manufacturing costs because, as it is necessary to manufacture a new cover according to the specifications of the current sensor provided inside, a cover must be provided for each current sensor specification.

[0008] Therefore, there is a need to improve this.

[0009] The present invention has been devised to improve upon the aforementioned problems, and aims to provide a fuse box for a vehicle battery that reduces mold investment costs by detachably covering a common cover on the body according to the vehicle, vehicle specifications, or current sensors of the fuse box that are not applied, and by providing a separate assembly cover that allows opening and closing of the part of the body corresponding to the current sensor, thereby using a relatively large common cover for common use and applying a relatively small assembly cover according to the specifications and non-application of the current sensor. means of solving the problem

[0010] A fuse box for a vehicle battery according to the present invention comprises: a body having a receiving space that is open to one side to accommodate a fuse; a common cover detachably connected to the body to cover the open side of the body while exposing a specific component, which is mounted differently according to specifications other than the fuse; an assembly cover detachably connected to at least one of the common cover and the body to cover or guide the exposure of the specific component mounted on the body; and a replacement assembly part that guides the assembly cover to be detachably assembled to at least one of the common cover and the body.

[0011] The above specific part is characterized by being accommodated at a position corresponding to one edge of the body within the above receiving space.

[0012] The above body is characterized by forming an elastic locking hook with a cut perimeter surface to secure the specific part mounted in the above receiving space and prevent detachment.

[0013] The assembly cover is characterized by forming an opening to guide the application of power to the specific part while covering the specific part housed in the body.

[0014] The above replacement assembly part includes a hinge pin formed in the body; and a rotation guide rib provided in the assembly cover and formed a hinge groove to receive the corresponding hinge pin, thereby guiding the rotation of the assembly cover with respect to the hinge pin.

[0015] The above-described replacement assembly includes: a locking projection formed protruding from both sides of the body; an elastic deformation rib extending from the assembly cover to be elastically deformable so as to correspond to each of the locking projections; and an elastic locking projection protruding from each of the elastic deformation ribs, which engages with the corresponding locking projection or induces elastic deformation of the elastic deformation rib and detaches from the corresponding locking projection depending on the rotational direction of the assembly cover.

[0016] The above assembly cover is characterized by extending and forming a flange that serves as a handle. Effects of the invention

[0017] As explained above, unlike the prior art, the fuse box for a vehicle battery according to the present invention allows for the detachable covering of a common cover on the body according to the vehicle, vehicle specifications, or current sensors of the fuse box that are not applied, and provides a separate assembly cover to open and close the part of the body corresponding to the current sensor. By using a relatively large common cover for general purposes and applying a relatively small assembly cover according to the specifications and non-application of the current sensor, the cost of mold investment can be reduced.

Specific details for implementing the invention

Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intention or convention of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0020] FIG. 1 is a perspective view of a fuse box for a vehicle battery according to one embodiment of the present invention, FIG. 2 is a perspective view with the cover of the fuse box for a vehicle battery separated according to one embodiment of the present invention, and FIG. 3 is a bottom perspective view with the cover of the fuse box for a vehicle battery separated according to one embodiment of the present invention.

[0022] FIG. 8 is a cross-sectional view of a key part of a fuse box for a vehicle battery in a closed state according to one embodiment of the present invention.

[0023] Referring to FIGS. 1 to 8, a fuse box (100) for a vehicle battery according to one embodiment of the present invention includes a body (110), a common cover (120), an assembly cover (130), and a replacement assembly part (140).

[0024] The fuse box (100) according to the present invention is electrically connected to the battery pack (not shown) of a vehicle.

[0025] At this time, the body (110) accommodates the fuse (10) and forms the outer shape of the fuse box (100).

[0026] In particular, the body (110) forms a receiving space (112) on one side (lower) to receive the fuse (10) in order to prevent external exposure of the fuse (10).

[0027] And, the common cover (120) is detachably attached to the body (110) to cover an open side of the body (110) while exposing specific parts (20) that are mounted differently according to specifications, other than the fuse (10). That is, when the common cover (120) is detachably attached to a set position of the body (110), the fuse (10), etc., mounted in the corresponding receiving space (112) of the body (110) is prevented from being exposed by the common cover (120), and specific parts (20) mounted in the receiving space (112) of another area of ​​the body (110) are exposed.

[0028] At this time, the specific part (20) is assumed to be a current sensor.

[0029] A specific component (20), which is a current sensor, is adopted according to each vehicle, each vehicle option, or its own specifications, and then mounted in the corresponding receiving space (112) of the common cover (120). Additionally, the specific component (20) may not be applied to the body (110) depending on the vehicle or the vehicle option. In other words, the common cover (120) is made common to protect the area where the fuse (10) is received, and the assembly cover (130) is formed to be interchangeable depending on the specifications or mounting status of the specific component (20).

[0030] In particular, when the fuse (10) and specific parts (20), etc. are mounted in the receiving space (112) of the body (110), the fuse (10) and specific parts (20), etc. may be mounted in the same receiving space (112) of the body (110) or may be mounted individually in partitioned receiving spaces (112).

[0031] Additionally, the assembly cover (130) is detachably connected to at least one of the common cover (120) and the body (110) to cover or guide the exposure of a specific part (20) mounted on the body (110).

[0032] That is, the assembly cover (130) is adopted in a size or shape that fits the specifications of a specific part (20) and is detachably connected to at least one of the common cover (120) and the body (110).

[0033] In addition, the assembly cover (130) serves to cover the corresponding part of the body (110) to which the specific part (20) is not applied.

[0034] Of course, the assembly cover (130) allows for partial opening and closing of the body (110), making it easy to replace or maintain specific parts (20).

[0035] Accordingly, a specific part (20) can be accommodated at a position corresponding to one edge of the body (110) in the receiving space (112).

[0036] In addition, the body (110) may form an elastic catch hook (114) with a cut perimeter to secure a specific part (20) mounted in the corresponding receiving space (112) and prevent it from coming off. As the elastic catch hook (114) elastically presses the corresponding specific part (20), the specific part (20) is fixed in a state of being received in the receiving space (112) of the body (110). Of course, the elastic catch hook (114) can be applied in various shapes and may be provided in at least two to elastically press the corresponding specific part (20) from both sides.

[0037] At this time, depending on the specifications of the specific part (20), the size or shape of the assembly cover (130) may vary.

[0038] That is, the assembly cover (130) forms an opening (132) to guide power supply to a specific part (20) while covering the specific part (20) housed in the body (110). Thus, the specific part (20) is provided with a connector (22) for power supply from the outside, and the connector (22) is provided to be exposed to the outside of the assembly cover (130) or partially protrude through the opening (132).

[0039] In particular, the specific part (20) may have different locations or shapes for which the connector (22) is provided depending on the specifications, and may not have the connector (22) provided.

[0040] Thus, the position of the opening (132) of the assembly cover (130) is set according to the specifications of the specific part (20). In addition, if the specific part (20) does not have a connector (22), the opening (132) of the assembly cover (130) becomes unnecessary.

[0041] So, the worker assembles the common cover (120) to the corresponding location on the body (110), and then assembles the assembly cover (130) that matches the specifications of the specific part (20) so that it is connected to at least one of the body (110) and the common cover (120).

[0042] Therefore, since only a relatively small assembly cover (130) can be applied according to the specifications of a specific part (20), the cost of mold investment can be reduced due to the commonization of the common cover (120).

[0043] Meanwhile, the selected assembly cover (130) can be firmly assembled to at least one of the body (110) and the common cover (120) by the replacement assembly part (140).

[0044] That is, the replacement assembly part (140) serves to guide the assembly cover (130) to be assembled so as to be detachably assembled to at least one of the common cover (120) and the body (110).

[0045] More specifically, the replacement assembly (140) may include a hinge pin (141), a rotation guide rib (142), a locking projection (144), an elastic deformation rib (146), and an elastic locking projection (147).

[0046] A hinge pin (141) is formed at a set position of the body (110). At this time, the hinge pin (141) may be provided as one or more in a circular, cylindrical, or polygonal shape.

[0047] In addition, the hinge pin (141) may be integrally provided with the body (110) or may be detachably connected to the body (110).

[0048] And, the rotation guide rib (142) is extended in the assembly cover (130) to correspond to the hinge pin (141). At this time, the rotation guide rib (142) forms a hinge groove (143) to accommodate the corresponding hinge pin (141).

[0049] In particular, when the hinge pin (141) enters the corresponding hinge groove (143), the rotation guide rib (142) elastically opens at that part. Then, when the hinge pin (141) fully enters the corresponding hinge groove (143), the rotation guide rib (142) elastically restores at that part to prevent the hinge pin (141) from coming off.

[0050] Accordingly, the rotation guide rib (142) and the assembly cover (130) rotate around the hinge pin (141) and open or close the specific part (20) or the corresponding receiving space (112) where the specific part (20) is mounted.

[0051] At this time, the hinge groove (143) is formed to correspond to the circumferential trajectory (shape) of the hinge pin (141).

[0052] Of course, the rotation guide rib (142) can be modified into various shapes.

[0053] In addition, the assembly cover (130) rotates around the hinge pin (141) and covers a specific part (20) or a corresponding receiving space (112) where the specific part (20) is mounted, and when shaking occurs, it collides with the body (110) and can generate noise.

[0054] Thus, the assembly cover (130) can be firmly attached to the body (110) while covering a specific part (20) or a corresponding receiving space (112) where the specific part (20) is mounted.

[0055] That is, for this purpose, a stopper portion (144), an elastic deformation rib (146), and an elastic stopper portion (147) are provided.

[0056] The stopper portion (144) is formed protruding from one or both sides of the body (110).

[0057] And, the elastic deformation rib (146) is extended in the assembly cover (130) so as to be elastically deformable so as to correspond to each of the stopper portions (144). At this time, the elastic deformation rib (146) can be applied in various shapes and can be provided in the assembly cover (130) either integrally or separately.

[0058] The elastic locking projection (147) protrudes from each elastic deformation rib (146) and, depending on the rotational direction of the assembly cover (130), engages with the corresponding locking projection (144) or induces elastic deformation of the elastic deformation rib (146) and detaches from the corresponding locking projection (144).

[0059] That is, as the assembly cover (130) rotates around the hinge pin (141) and covers a specific part (20) or a corresponding receiving space (112) on which the specific part (20) is mounted, the elastic deformation rib (146) is elastically deformed to the outside of the assembly cover (130), and the elastic locking projection (147) moves along the corresponding locking projection (144).

[0060] And, when the assembly cover (130) is fully rotated around the hinge pin (141), the elastic locking projection (147) moves along the corresponding locking projection (144) and then elastically restores together with the elastic deformation rib (146) and gets caught on the locking projection (144).

[0061] Conversely, as the assembly cover (130) rotates around the hinge pin (141) to open a specific part (20) or a corresponding receiving space (112) to which the specific part (20) is mounted, the elastic deformation rib (146) is elastically deformed to the outside of the assembly cover (130), and the elastic locking projection (147) is forcibly moved along the corresponding locking projection (144). Thus, the assembly cover (130) is allowed to open.

[0062] In particular, the assembly cover (130) can be rotated around the hinge pin (141) to cover a specific part (20) or a corresponding receiving space (112) where the specific part (20) is mounted, and the elastic locking projection (147) can move smoothly along the locking projection (144), so that the locking projection (144) can form an inclined surface (145).

[0063] Meanwhile, the assembly cover (130) may extend and form a flange (134) that serves as a handle for rotational guidance. At this time, the flange (134) can be modified into various shapes.

[0064] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the claims below. Explanation of the symbols
