Description

Technical Field

[0001] This utility model relates to the technical field of vehicle low-voltage wiring harness systems, specifically to a power supply positive terminal distribution box and a vehicle. Background Technology

[0002] With the development of electric and intelligent vehicles, the number of devices in vehicles that require electricity is increasing. Currently, the power distribution in new energy vehicles is usually done by directly branching through external copper terminals when the overall current allows, which poses a significant safety hazard.

[0003] To address this, related technologies combine the positive terminal, positive fuse box, and positive junction box for power distribution, which can improve connection safety to some extent. However, different fuse models correspond to different sizes; for example, MEGA fuses (high-current slow-blow fuses) are larger, while MIDI fuses (medium-current slow-blow fuses) are smaller. Furthermore, the limiting structures inside the fuse box for installing MEGA and MIDI fuses are dedicated structures, resulting in low internal space utilization and difficulty in controlling the box size. Therefore, based on the diversified, personalized, and multi-vehicle demands of the market, separate box molds need to be developed for different optional vehicle models. This not only leads to high tooling and mold investment costs and a heavy production burden, but also results in bloated and complex production lines, difficult management, and challenges in ensuring product quality.

It is understood that the above-mentioned terms indicating orientations or positional relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] like Figures 1 to 3 as well as Figure 5As shown, this embodiment provides a power supply positive terminal distribution box, including: a box body 1, a fuse module 2, and a conductive plate 3; the box body 1 has a first chamber 11, a second chamber 12, and a third chamber 13 inside, the two ends of the first chamber 11 are respectively connected to the second chamber 12 and the third chamber 13, and the first chamber 11 and the second chamber 12 constitute a first mounting area 101; the fuse module 2 includes a main circuit fuse module 21 disposed in the first mounting area 101, the main circuit fuse module 21 is a first fuse module 201 or a second fuse module 202 with a size larger than the first fuse module 201, and both the first fuse module 201 and the second fuse module 202 are made of The device comprises a fuse and mounting bases adapted to both ends of the fuse, and is detachably connected to the housing 1 via the mounting bases; the conductive piece 3 is disposed in the third chamber 13 and has a first connecting part 31 and a second connecting part 32. The first connecting part 31 is connected to the positive terminal of the battery to form an input terminal, and the second connecting part 32 extends into the first chamber 11 and is connected to the fuse on the main circuit fuse module 21 to form an output terminal; wherein, when the main circuit fuse module 21 is the first fuse module 201, the mounting bases at both ends of it are both housed in the first chamber 11; when the main circuit fuse module 21 is the second fuse module 202, the mounting bases at both ends of it are respectively housed in the first chamber 11 and the second chamber 12. In this way, after connecting the first chamber 11 and the second chamber 12 to form the first installation area 101, the second chamber 12 can be used to supplement and expand the installation space of the first chamber 11. This allows the first installation area 101 to not only meet the installation requirements of the first fuse module 201, but also to be compatible with the installation of the larger second fuse module 202. This effectively improves the space utilization and versatility of the box 1 and reduces the development and production costs of the box 1 mold.

[0026] Specifically, such as Figures 1 to 6As shown, the power supply positive terminal distribution box in this embodiment includes a box body 1 and a box cover 4. The box body 1 has an internal accommodating space including a first chamber 11, a second chamber 12, and a third chamber 13. The box cover 4 is movably or detachably connected to the box body 1 to close or open the accommodating space. An installation bracket 5 is also provided on the outside of the box body 1, which can be connected to the vehicle body or battery to fix the box body 1. Inside the box body 1, the first chamber 11, the second chamber 12, and the third chamber 13 are distributed on the same horizontal plane. The height and width of the first chamber 11 are adapted to the installation height and width of the second fuse module 202, and the length of the first chamber 11 is adapted to the installation length of the first fuse module 201. The third chamber 13 is located at one end of the length direction of the first chamber 11 and communicates with the first chamber 11; its size is adapted to the installation size of the conductive piece 3. The second chamber 12 is located at the other end of the length direction of the first chamber 11 and communicates with the first chamber 11. The length direction of the first chamber 11 is the first direction x, and the width direction of the first chamber 11 is the second direction y. The dimension of the second chamber 12 in the first direction x, combined with the length dimension of the first chamber 11, is adapted to the installation length of the second fuse module 202. The dimension of the second chamber 12 in the second direction y is adapted to the installation width of the second fuse module 202. In this way, the first chamber 11 and the second chamber 12 constitute the first installation area 101 that can be compatible with the installation of the first fuse module 201 and the second fuse module 202. The overall structure is compact and reasonable, with high space utilization and versatility.

[0027] It is understood that the mounting bases at both ends of the fuse module include a mounting base body and studs on the mounting base body. The fuse is installed by fitting both ends of the fuse onto the two studs and screwing nuts into the studs for tightening. At the same time, the upper part of the mounting base body is used to support the fuse and can be configured with a limiting structure to improve the connection stability of the fuse. The lower part of the mounting base body is used to connect with the housing 1. A corresponding connection structure is configured between the mounting base and the housing 1. The detachable connection with the housing 1 can be achieved by means including but not limited to snap-fit, plug-in, and bolt connection. For example, the mounting base can be detachably connected to the housing 1 by using a corresponding plug-in hole and bolt connection, or by using a limiting slot and an elastic snap-fit ​​piece that extends and retracts perpendicular to the slot opening direction. For specific connection structures, please refer to the prior art, which will not be elaborated here.

[0028] Furthermore, fuses can be classified into MINI fuses (miniature fast-blow fuses), MIDI fuses (medium current slow-blow fuses), and MEGA fuses (high current slow-blow fuses) according to their applicable current range. MINI fuses are smaller than MIDI fuses, and MIDI fuses are smaller than MEGA fuses. In this case, the studs of the mounting bracket will be replaced with the corresponding compatible model according to the fuse type. At the same time, the shape of the conductive piece 3 and the distance between the two ends of the fuse will also vary depending on the fuse type.

[0029] For example, such as Figures 1 to 3 As shown, in this embodiment, the first fuse module 201 is a MIDI fuse module, consisting of a MIDI fuse and two first mounting bases adapted to the MIDI fuse. The studs and nuts corresponding to the first mounting bases are of type M6. The second fuse module 202 is a MEGA fuse module, consisting of a MEGA fuse and two second mounting bases adapted to the MEGA fuse. The studs and nuts corresponding to the second mounting bases are of type M8. When the main circuit fuse module 21 is the first fuse module 201, the conductive piece 3 with corresponding sized holes is fitted onto the M6 ​​stud of one of the first mounting bases. Then, the two ends of the MIDI fuse are fitted onto the M6 ​​studs of the two first mounting bases respectively. Finally, the M6 ​​nuts are screwed into the M6 ​​studs and tightened to complete the installation of the MIDI fuse. Similarly, when the main circuit fuse module 21 is the second fuse module 202, the MEGA fuse can be installed using second mounting bases with M8 studs and M8 nuts. It can be seen that the adaptability of the first mounting base and the second mounting base can be limited to the upper part of the mounting base body. In this regard, the lower part of the mounting base body of the first mounting base and the second mounting base can be detachably connected to the box 1 with the same size and position of the connection structure, so as to ensure the universality of the structure of the box 1 for realizing the detachable connection.

[0030] In other embodiments, the first fuse module 201 may also be a MINI fuse module, and the second fuse module 202 may be a MIDI fuse module; or, the first fuse module 201 may be a MINI fuse module, and the second fuse module 202 may be a MEGA fuse module. When the first fuse module 201 is a MINI fuse module and the second fuse module 202 is a MEGA fuse module, the MINI and MEGA fuse modules have a significant size difference. To address this, the MINI fuse of the MINI fuse module can be adapted to the mounting bracket of the MIDI fuse module via an adapter, and then connected to the housing 1 via the mounting bracket of the MIDI fuse module. This reduces the size compatibility differences of the housing 1 for the installation of the MINI and MEGA fuse modules, ensuring the structural versatility of the housing 1.

[0031] Furthermore, the mounting bases at both ends of the fuse can be integrated, that is, the two mounting bases are integrally formed and connected. This can improve the structural stability of the fuse module and the ease of connection between the mounting base and the housing 1. At the same time, the middle part of the mounting base can also support the middle part of the fuse, thereby improving the connection stability between the mounting base and the fuse and preventing the fuse from deforming due to the middle part being suspended.

[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, the mounting base at one end of the main circuit fuse module 21 is set at the connection between the first chamber 11 and the third chamber 13. The second connecting part 32 of the conductive piece 3 extends into the first chamber 11 and can be directly connected to one end of the main circuit fuse module 21. The first chamber 11 and the second chamber 12 are respectively provided with a first port 111 and a second port 121 for external communication. When the main circuit fuse module 21 is the first fuse module 201, the mounting base at its other end is set at the first port 111. In this way, a terminal 6 can be set at the first port 111 and connected to the other end of the first fuse module 201 to transmit power to the outside through the first port 111. When the main circuit fuse module 21 is the second fuse module 202, the mounting base at its other end is set at the second port 121. In this way, a terminal 6 can be set at the second port 121 and connected to the other end of the second fuse module 202 to transmit power to the outside through the second port 121. The above settings reduce the number of wiring harness loop connections, facilitate wiring, and ensure that the output terminal location is clear, making it easy to identify and connect the corresponding output terminal.

[0033] In some embodiments, such as Figure 2 and Figure 7 As shown, the third chamber 13 is provided with a third port 131 that communicates with the outside; the first connecting part 31 of the conductive piece 3 is provided corresponding to the third port 131, and is connected to the positive terminal of the battery through the third port 131 to form an input terminal. Specifically, in this embodiment, the first connecting part 31 extends out of the third chamber 13 from the third port 131 and is connected to the positive terminal of the battery outside the housing 1. In this way, the space occupied inside the housing 1 can be reduced, the volume of the housing 1 can be optimized, and the miniaturization and flattening of the housing 1 can be achieved.

[0034] In some embodiments, such as Figures 1 to 3 as well as Figure 6As shown, the interior of the housing 1 also has a fourth chamber 14, which communicates with the second chamber 12 and has a fourth port 141 for external communication. When the main circuit fuse module 21 is the first fuse module 201, the second chamber 12 and the fourth chamber 14 constitute a second mounting area 102. The fuse module also includes a branch circuit fuse module 22 located within the second mounting area 102. The branch circuit fuse module 22 is either the first fuse module 201 or the second fuse module 202, and its mounting bases at both ends are respectively housed in the fourth chamber 14 and the second chamber 12. In this way, the empty second chamber 12 can be used to supplement and expand the installation space of the fourth chamber 14, so that the second installation area 102 can be used for the installation of the branch fuse module 22. At this time, by setting the wiring terminals 6 at the second port 121 and the fourth port 141 respectively and connecting them to the two ends of the branch fuse module 22, and then connecting another battery to the outside through the wiring terminal 6 at the second port 121, and transmitting power to the outside through the wiring terminal 6 at the fourth port 141, the second installation area 102 can be used as a redundant power transmission line, reducing the probability of the power distribution box failure.

[0035] It is understandable that the height of the second chamber 12 and its dimensions in the first x and second y directions are sufficient for the installation of the second fuse module 202. Accordingly, the height of the fourth chamber 14 and its dimensions in the first x direction correspond to those of the second chamber 12. The dimensions of the fourth chamber 14 in the second y direction, combined with those of the second chamber 12 in the second y direction, are adapted to the installation length of the second fuse module 202. The second chamber 12 and the fourth chamber 14 together constitute the second installation area 102 for the installation of the shunt fuse module 22, resulting in a reasonable space design and high space utilization. Alternatively, the dimensions of the fourth chamber 14 in the second y direction, combined with those of the second chamber 12 in the second y direction, can be adapted to the installation length of the first fuse module 201, while keeping other dimensions unchanged. The second chamber 12 and the fourth chamber 14 then constitute the second installation area 102 for the shunt fuse module 22 to be installed on the first fuse module 201, making the structure more compact and further reducing the volume of the housing 1. Furthermore, the connection method between the branch fuse module 22 and the housing 1, the conductive piece 3 and the terminal block 6 is the same as the corresponding connection method of the main fuse module 21 mentioned above, and will not be repeated here.

[0036] In some embodiments, such as Figure 1 and Figure 2As shown, when the main circuit fuse module 21 is the first fuse module 201, its mounting base near the second mounting area 102 is provided with a baffle 211, which is positioned between the first chamber 11 and the second chamber 12. The baffle 211 isolates the first chamber 11 from the second mounting area 102, preventing the heat or arc generated when the fuse blows from affecting the fuses in adjacent areas, thus improving the safety performance of the distribution box.

[0037] In some embodiments, such as Figures 1 to 3 As shown, the third chamber 13 is located adjacent to the first chamber 11 and the fourth chamber 14. In this configuration, the first chamber 11, the second chamber 12, the third chamber 13, and the fourth chamber 14 are all distributed on the same horizontal plane. The first chamber 11 and the fourth chamber 14 intersect perpendicularly with the second chamber 12 on adjacent sides of the third chamber 13, resulting in a compact, rectangular structure with high space utilization. The fuse module also includes multiple branch fuse modules 23 located within the third chamber 13, which are connected in parallel. Between the first connecting part 31 and the second connecting part 32 is the third connecting part 33 of the conductive piece 3. One end of the branch fuse module 23 is connected to the third connecting part 33, and the other end passes through the terminal block 6 to the side wall of the third chamber 13 to form an output terminal. By arranging multiple branch fuse modules 23, multiple power transmission lines with different currents can be formed to meet the power supply needs of various electrical appliances.

[0038] It is understood that the side wall of the third chamber 13 can have a corresponding port facing the end of the branch fuse module 23, and a terminal block 6 is provided at this port to connect with the branch fuse module 23 to form an output terminal for external power transmission. The connection method between the branch fuse module 23 and the box 1, the conductive piece 3 and the terminal block 6 is the same as the corresponding connection method of the main fuse module 21 mentioned above, and will not be repeated here. In addition, a partition is provided around the branch fuse module 23, which can isolate the branch fuse module 23 separately, thereby improving the safety performance of the distribution box.

[0039] Furthermore, such as Figures 1 to 3As shown, the multi-branch fuse module 23 includes a set of second fuse modules 202 and several sets of first fuse modules 201 (three sets in this embodiment). Since the first chamber 11 and the main fuse module 21 disposed in the first chamber 11 are arranged along the first direction x, the conductive piece 3 connected to the main fuse module 21 and the fourth chamber 14 are spaced apart in the first direction x. This space is sufficient to allow the branch fuse module 23 to be arranged along the second direction y. Therefore, the second fuse module 202 of the branch fuse module 23 can be disposed on the side of the third connecting part 33 near the fourth chamber 14, and the orientation of its end is parallel to the setting direction of the branch fuse module 22, i.e., the second direction. The third connecting portion 33 extends towards the side closer to the fourth chamber 14 to form a connecting end for connecting the second set of second fuse modules 202 of the branch fuse module 23. Based on the arrangement of the second set of second fuse modules 202 of the branch fuse module 23, the conductive piece 3 can extend along the second direction y to the same length as the second set of second fuse modules 202 of the branch fuse module 23. Thus, the three sets of first fuse modules 201 of the branch fuse module 23 can be located on the side of the third connecting portion 33 away from the fourth chamber 14, with their ends oriented parallel to the setting direction of the main fuse module 21 (i.e., the first direction x) and spaced apart along the setting direction of the branch fuse modules 22 (i.e., the second direction y). Based on this arrangement, the housing 1 can have a compact, rectangular structure with high space utilization, achieving miniaturization and flattening of the housing 1 while ensuring multi-output requirements are met.

[0040] In some embodiments, such as Figures 1 to 4As shown, the interior of the housing 1 also has a fifth chamber 15, which is adjacent to the third chamber 13 and located on the opposite side of the first chamber 11. One end of the fifth chamber 15 is connected to the first chamber 11, and the other end is flush with the side of the third chamber 13 away from the fourth chamber 14. It also has a fifth port 151 for external communication. The fifth chamber 15 has a first mounting base 152 for the first fuse module 201. At this time, the first connecting part 31 of the conductive piece 3 can be extended along the first direction x to connect with the first mounting base 152 in the fifth chamber 15, and then a terminal 6 can be set at the fifth port 151 to be directly connected to the conductive piece 3 for external power transmission. Alternatively, a first fuse module 201 can be arranged in the fifth chamber 15. When the main circuit fuse module 21 is the first fuse module 201, one end of the first fuse module 201 in the fifth chamber 15 can share a mounting base with the main circuit fuse module 21 to connect to the conductive piece 201. The first connecting part 31 of the through piece 3 is connected at one end to the first mounting base 152 inside the fifth chamber 15, and transmits power externally through the terminal block 6 provided at the fifth port 151. When the main circuit fuse module 21 is the second fuse module 202, one end of the first fuse module 201 inside the fifth chamber 15 can extend into the first chamber 11 and be soldered to the through piece 3, while the other end is connected to the first mounting base 152 inside the fifth chamber 15, and transmits power externally through the terminal block 6 provided at the fifth port 151. With the above configuration, the fifth chamber 15 can be used as a reserved power transmission line to meet the diverse power supply needs of the distribution box.

[0041] In summary, as Figures 8 to 13 As shown in the description of the above embodiments, the power positive terminal distribution box of this application can realize multiple power outputs in a compact and limited space by reasonably dividing the space of the box. It also has the compatibility of installing different types of fuse modules, integration of redundant power transmission lines, and arrangement of reserved power transmission lines. This allows the box to realize at least six structural arrangements, including type a (non-redundant + 2 MAGE + 3 MIDI), type b (non-redundant + 2 MAGE + 4 MIDI), type c (non-redundant + 1 MAGE + 4 MIDI), type d (non-redundant + 1 MAGE + 5 MIDI), type e (redundant + 1 MAGE + 5 MIDI), and type f (redundant + 1 MAGE + 6 MIDI).
