Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to electrical distribution boxes, electrical distribution systems, and vehicles. Background Technology

[0002] The battery is a very important component of the vehicle's electrical system. It not only stores the electrical energy generated by the generator when the vehicle is in motion, but also works with the power distribution system to supply power to many of the vehicle's electrical systems.

[0003] In order to safely and smoothly distribute the battery's power to various power systems, it is usually necessary to install a distribution box on the battery's output terminals to distribute the output power.

[0004] Currently, with the development of new technologies and changes in market demand, various models with different configurations are constantly emerging, such as L2, L3 and various other personalized configuration models. Existing power distribution boxes have poor compatibility and are relatively large in size. Summary of the Invention

[0005] The purpose of this invention is to provide a power distribution box, a power system, and a vehicle to solve the problems of poor compatibility and excessive size of current power distribution boxes.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A distribution box, connected to the terminals of a storage battery, wherein the terminals are disposed on a recessed portion of the storage battery, comprising:

[0008] The base is fitted into the recessed portion and has a stepped portion for fixing the busbar. The fire bolt is screwed onto the step in the middle section of the stepped portion.

[0009] The upper cover is disposed on the base, and the upper cover and the base form a first cable outlet and a second cable outlet, the first cable outlet and the second cable outlet having different orientations.

[0010] As an optional solution for the distribution box, the busbar is stepped, and the steps of the busbar are attached one by one to the steps of the stepped section.

[0011] As an optional power distribution box solution, the base has a positioning hole, and the pole passes through the positioning hole.

[0012] As an alternative to the distribution box, the first outlet is perpendicular to the extension direction of the second outlet.

[0013] As an alternative to the power distribution box, the top cover extends with a downward-opening isolation cover, which, together with the base, forms a second cable outlet.

[0014] According to the power distribution box of the claim, the base is provided with a plurality of protrusions, and a fuse is fixed on the protrusions, the fuse being electrically connected to the busbar.

[0015] As an optional solution for the power distribution box, the outer wall of the base is provided with a slot, the power distribution box includes an expansion module, the outer wall of the expansion module is provided with a card plate, and the card plate can be engaged with the slot.

[0016] As an optional power distribution box solution, one of the base and the expansion module is provided with a sliding groove, and the other is provided with a sliding rail, the sliding rail being able to slide in the sliding groove.

[0017] The power distribution system includes a storage battery and a power distribution box as described in any of the above embodiments, wherein the power distribution box is electrically connected to the storage battery.

[0018] The vehicle includes a chassis and a power distribution system according to the above-described scheme, wherein the power distribution system is located on the chassis.

[0019] Beneficial effects:

[0020] In a first aspect, by embedding the base within a recessed portion, the base mates with a recess near the battery terminal. This recessed portion is typically located at the top corner of the battery and has a recessed structure with clearance. A terminal is located in the middle of this structure. To accommodate this recessed structure, embedding the base of the distribution box within the recessed portion optimizes the assembly space between the distribution box and the battery, resulting in a smaller overall footprint and greater compactness. Furthermore, by providing a stepped portion on the base for fixing the busbar, and attaching the fuse bolt to the middle step of the stepped portion, the height occupied by the fuse bolt is reduced compared to existing non-stepped distribution box bases, resulting in a smaller overall height and volume of the distribution box. Furthermore, by forming a first and second cable outlet with the top cover and base, and by having the first and second cable outlets facing different directions, the distribution box can be adapted to power interfaces with different orientations, improving its adaptability.

[0021] In a second aspect of the invention, the distribution system equipped with the distribution box has a more compact structure.

[0022] In a third aspect, the power supply location of a vehicle equipped with this power distribution system is more flexible. Attached Figure Description

[0042] Please see the appendix Figure 1 -Appendix Figure 7 The first aspect of this embodiment relates to a power distribution box, which is connected to the terminal 110 of a storage battery 100. The terminal 110 is disposed on the recess 120 of the storage battery 100. Specifically, the power distribution box includes a base 1 and a top cover 2. The base 1 can be embedded in the recess 120. The base 1 is provided with a stepped portion 11 for fixing a busbar 3. A fire bolt 4 is screwed onto the stepped portion 11 and is located on the middle step. The top cover 2 is disposed on the base 1. The top cover 2 and the base 1 surround to form a first outlet 21 and a second outlet 22. The first outlet 21 and the second outlet 22 have different orientations.

[0043] In this embodiment, by embedding the base 1 within the recess 120, the base 1 mates with the recess 120 near the terminal post 110 of the battery 100. This recess 120 is typically located at the top corner of the battery 100 and has a recessed structure for clearance. The terminal post 110 is located in the middle of this structure. To accommodate this recessed structure, embedding the base 1 of the distribution box within the recess 120 optimizes the assembly space between the distribution box and the battery 100, resulting in a smaller and more compact overall footprint. Furthermore, through... The base 1 is provided with a stepped part 11 that can fix the busbar 3. The fire bolt 4 is connected to the step in the middle of the stepped part 11. Compared with the existing non-stepped structure of the power distribution box base, it can ensure that the height occupied by the fire bolt 4 is smaller, so that the overall height of the power distribution box is smaller and the volume occupied is smaller. Furthermore, by making the upper cover 2 and the base 1 surround to form a first outlet 21 and a second outlet 22, the first outlet 21 and the second outlet 22 have different orientations, which can be adapted to power interfaces with different orientations, thus improving the adaptability of the power distribution box.

[0044] Those skilled in the art will understand that the ignition bolt 4 is used to achieve external ignition power by clamping the ignition bolt 4 with a conductive clip when the auxiliary vehicle cannot be started normally. The ignition bolt 4 is an existing structure, and the technical details of this structure will not be described further.

[0045] Optionally, the busbar 3 is stepped, and the steps of the busbar 3 are attached to the steps of the stepped portion 11 one by one. Adaptively, the busbar 3 in this embodiment is also stepped, and is attached to the stepped portion 11 one by one. The stepped portion 11 is used for positioning the busbar 3 and for fixing the fire bolt 4 to the stepped electrical connection located in the middle section of the busbar 3.

[0046] Optionally, a positioning hole 12 is provided on the base 1, and the terminal post 110 passes through the positioning hole 12. The terminal post 110 is positioned in the positioning hole 12 to position the base 1, thereby accurately positioning the entire distribution box relative to the battery 100. In this embodiment, since the terminal post 110 extends upward through the positioning hole 12, the side wall of the terminal post 110 may interfere with part of the stepped portion 11 and the busbar 3. Avoidance grooves are provided on the stepped portion 11 and the busbar 3 to avoid some structures of the terminal post 110.

[0047] Optionally, the extension directions of the first outlet 21 and the second outlet 22 are perpendicular. By making the extension directions of the first outlet 21 and the second outlet 22 perpendicular, the power supply requirements of different vehicle models at different locations can be accommodated. For example, the first outlet 21 extends horizontally, and the second outlet 22 extends vertically. The power supply of the L2 vehicle model is electrically connected to the distribution box via the first outlet 21; the power supply of the L3 vehicle model is electrically connected to the distribution box via the second outlet 22.

[0048] Furthermore, the upper cover 2 extends with a downward-facing isolation cover 23, which, together with the base 1, forms a second cable outlet 22. The downward-facing opening of the isolation cover 23 causes the opening of the second cable outlet 22 to face downwards. Furthermore, the isolation cover 23 can be directly placed over the interface, facilitating safe power extraction.

[0049] Optionally, the base 1 is provided with multiple protrusions 13, and a safety piece 5 is fixed on the protrusion 13. The safety piece 5 is electrically connected to the busbar 3. The protrusions 13 can limit the height of the safety piece 5, and the safety piece 5 is fixed to the protrusion 13 by screws or rivets. In this embodiment, each safety piece 5 is connected to the protrusion 13 at both ends by two fasteners (screws or rivets). One end is electrically connected to the busbar 3, and the other end is used for wiring to the power supply.

[0050] Optionally, the outer wall of the base 1 is provided with a slot 14, and the power distribution box includes an expansion module 6. The outer wall of the expansion module 6 is provided with a card plate 61, which can engage with the slot 14. Please refer to the appendix for further details. Figure 1 Appendix Figure 3 and attached Figure 7 In this embodiment, the expansion module 6 and the power distribution box can be easily detached by the card plate 61 and the card slot 14, which facilitates the personalized functional expansion of the vehicle in the future. For example, after the vehicle is assembled, if the customer has requirements such as seat heating or seat ventilation, the expansion module 6 can be directly connected to the card slot 14 by the card plate 61 and the expansion module 6 can be connected to the power distribution box for power. This facilitates the spatial layout and fixation of the expansion module 6 and avoids the use of screws or adhesives, making the fixing method simple and reliable.

[0051] Optionally, the base 1 and the slot 14 are integrated, and the expansion module 6 and the card plate 61 are integrated. One end of the card plate 61 is fixed to the outer wall of the expansion module 6, and the other end extends in a direction away from the expansion module 6 to form an extension end. During assembly, reliable engagement is achieved by inserting the extension end into the slot 14.

[0052] Optionally, one of the base 1 and the expansion module 6 is provided with a sliding groove 15, and the other is provided with a sliding rail 62, which can slide in the sliding groove 15. In this embodiment, the outer wall of the base 1 is provided with a sliding groove 15, and the outer wall of the expansion module 6 is provided with a sliding rail 62. Specifically, the two sliding grooves 15 are located on both sides of the slot 14, and correspondingly, the two sliding rails 62 are located on both sides of the locking plate 61. During assembly, the sliding rail 62 slides and engages with the sliding groove 15 through the end of the sliding groove 15 near the bottom, and slides upward until the locking plate 61 is stably locked into the slot 14.

[0053] The second aspect of this embodiment also relates to a power distribution system, which includes a battery 100 and the aforementioned distribution box, the distribution box being electrically connected to the battery 100. The power distribution system equipped with this distribution box has a more compact overall structure.

[0054] The third aspect of this embodiment also relates to a vehicle that includes a chassis and the aforementioned power distribution system mounted on the chassis, thereby making the power supply location of the vehicle more flexible.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
