Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0036] The following reference Figures 1 to 8 This application describes a battery housing and battery case according to some embodiments.
[0037] Example 1
[0038] See Figures 1 to 8 As shown, an embodiment of this application provides a battery box, including: a main box 1, a support member 2, a junction box 3, and a waterproof lead member 4; wherein, the junction box 3 is connected to the main box 1, and the interior of the junction box 3 is connected to the interior of the main box 1, that is, the main box 1 is provided with a first opening, the junction box 3 is provided with a second opening, and the first opening and the second opening are arranged opposite to each other and connected.
[0039] The support component 2 is located inside the main enclosure 1 and is used to install electrical components such as connectors. It can be seen that placing the support component 2 inside the main enclosure 1 can make full use of the space inside the main enclosure 1 and reduce the size of the junction box 3. It should be noted that the support component 2 is not limited to being located inside the main enclosure 1. It can also be located inside the junction box 3, or partly inside the main enclosure 1 and partly inside the junction box 3, depending on the actual needs. In addition, it should also be noted that other types of electrical components can be installed on the support component 2, depending on the actual needs.
[0040] The waterproof lead wire component 4 is installed in the junction box 3, and the waterproof lead wire component 4 has a lead wire through hole, which is used to lead the wire harness inside the junction box 3 to the outside of the junction box 3.
[0041] As can be seen from the structure described above, this application no longer uses the side panel of the battery box as the output end plate. Instead, it sets up a separate structure of support member 2 and junction box 3. The support member 2 is directly installed inside the main box 1, and the corresponding connector is installed on the support member 2. Then, the junction box 3 is installed at the open end of the main box 1 for sealing. That is to say, the connector is built in, and all the wire harnesses connected to the connector are concentrated in the junction box 3. Finally, the wire harnesses that need to be led out are led out through the waterproof lead wire member 4, thereby solving the waterproof problem caused by the external connector. In other words, the investment in the waterproof structure of the external connector is reduced, which greatly reduces the product cost and installation difficulty, and at the same time reduces the possible leakage points, making it safer and more reliable.
[0042] In this embodiment, preferably, as follows: Figures 1 to 5 As shown, along the height direction of the main enclosure 1, the junction box 3 is located at the top of the main enclosure 1.
[0043] As described above, placing the junction box 3 at the top of the main enclosure 1 makes full use of the vertical space, resulting in a more aesthetically pleasing appearance and easier transportation. This avoids the problems associated with placing the junction box 3 on the side of the main enclosure 1, which would cause a protruding part on the side, resulting in an unsightly appearance and inconvenience for transportation. Of course, this is not the only option; the junction box 3 can also be placed on the side of the main enclosure 1, depending on the specific needs.
[0044] In this embodiment, preferably, as follows: Figures 1 to 4 As shown, the battery box also includes a shielding member 5. Along the height direction of the main box 1, the shielding member 5 is disposed on the top of the main box 1 and connected to the main box 1. From the front end plate of the main box 1 toward its back plate, the shielding member 5 shields the junction box 3 and the waterproof lead wire member 4.
[0045] As can be seen from the structure described above, the shielding component 5 is used to cover the junction box 3 and the waterproof lead component 4, so that the above structure is not exposed and is more aesthetically pleasing.
[0046] In this embodiment, preferably, as follows: Figure 6 As shown, the front panel of the junction box 3 near the shielding member 5 has an avoidance opening 31, and an annular protrusion 32 is formed on the outer periphery of the avoidance opening 31. The annular protrusion 32 has an annular flange 33, and the annular flange 33 abuts against the shielding member 5.
[0047] As can be seen from the structure described above, an avoidance opening 31 is provided on the junction box 3, which facilitates the connection of wire harnesses and other operations within the junction box 3, or facilitates subsequent maintenance and other work. Moreover, an annular flange 33 is provided on the outer periphery of the avoidance opening 31, so that the annular flange 33 can abut against the shielding member 5, thereby achieving a circumferential seal on the avoidance opening 31, which serves to prevent water and dust.
[0048] Furthermore, preferably, a sealing ring can be compressed between the annular flange 33 and the shielding member 5 to further seal the area.
[0049] In this embodiment, preferably, as follows: Figure 6 As shown, the battery box also includes a connecting member 6, which is fixed to the junction box 3 and is located on the outside of the annular protrusion 32. The connecting member 6 abuts against the junction box 3 and is detachably connected to the junction box 3 by a first fastening member. The connecting member 6 is detachably connected to the shielding member 5 by a second fastening member.
[0050] As can be seen from the structure described above, since the aforementioned annular protrusion 32 protrudes from the front end face of the junction box 3, the aforementioned connecting member 6 is used to assist in supporting the front shielding member 5 and to provide a fixing point for fixing the shielding member 5.
[0051] Furthermore, preferably, along the direction perpendicular to the first direction a, that is, the second direction b (and preferably, the second direction b refers to the length direction of the main box 1, but of course, it is not limited to this), the aforementioned connecting members 6 are provided on both opposite outer sides of the annular protrusion 32, thereby improving the support and fixation effect on the shielding member 5.
[0052] Furthermore, preferably, the connecting member 6 is a U-shaped frame, and the opening of the connecting member 6 is positioned facing the annular protrusion 32, which contributes to lightweight design. Of course, it is not limited to this; the connecting member 6 can also adopt other structures, such as a beam structure.
[0053] In this embodiment, preferably, as follows: Figure 4 As shown, the shielding member 5 is a cover structure, and its opening is set towards the junction box 3.
[0054] As can be seen from the structure described above, the shielding component 5 adopts a box-like structure, with the flanges around it serving to shield, prevent dust, and waterproof. Of course, it is not limited to this; the shielding component 5 can also adopt other structures, such as a flat panel structure, etc.
[0055] In this embodiment, preferably, as follows: Figures 1 to 4 , Figure 7As shown, along the height direction of the main enclosure 1, the outer edge of the projection of the junction box 3 and the outer edge of the waterproof lead wire component 4 do not exceed the outer edge of the projection of the main enclosure 1. This avoids lengthening and / or widening the battery enclosure, saving space and reducing costs. Especially when there is a gap between the outer edge of the projection of the junction box 3 and the outer edge of the projection of the main enclosure 1, the waterproof lead wire component 4, when installed on the side of the junction box 3, will not protrude beyond the shielding component 5, which is the same length as the main enclosure 1, resulting in a more aesthetically pleasing appearance and without increasing the overall size of the battery enclosure. Of course, this is not the only limitation; along the height direction of the main enclosure 1, the outer edge of the projection of the junction box 3 can also exceed the outer edge of the projection of the main enclosure 1, depending on the specific design requirements.
[0056] In this embodiment, preferably, as follows: Figures 1 to 4 As shown, both the junction box 3 and the main enclosure 1 are rectangular parallelepipeds. The length direction of the junction box 3 is the same as the length direction of the main enclosure 1, the width direction of the junction box 3 is the same as the width direction of the main enclosure 1, and the center line of the junction box 3 along its height direction coincides with the center line of the main enclosure 1 along its height direction.
[0057] As described above, arranging the junction box 3 and main enclosure 1 in this manner makes the overall battery enclosure more harmonious and aesthetically pleasing, avoiding local structural misalignment or twisting. Of course, the arrangement of the junction box 3 and main enclosure 1 is not limited to this; it can be designed according to actual needs.
[0058] In this embodiment, preferably, as follows: Figure 1 and Figure 4 As shown, the front end plate of the main housing 1 faces the back plate in the first direction a, and along the direction perpendicular to the first direction a, that is, the second direction b (and preferably, the second direction b refers to the length direction of the main housing 1, but of course, it is not limited to this), handles are provided on both sides of the junction box 3. Of course, it is not limited to this, and handles 7 can also be provided only on one side of the junction box 3.
[0059] Furthermore, preferably, the aforementioned handle 7 is hidden behind the shielding member 5, which is more aesthetically pleasing.
[0060] In this embodiment, preferably, as follows: Figure 1 and Figure 4 As shown, the direction of the front end plate of the main housing 1 toward its back plate is the first direction a, and along the direction perpendicular to the first direction a, for example, in this embodiment, it preferably refers to the length direction of the main housing 1. The waterproof lead wire component 4 is disposed on the side of the junction box 3.
[0061] As can be seen from the structure described above, the waterproof lead wire component 4 is set on the side of the junction box 3, making full use of the side space and avoiding the aesthetics of setting it on the front, or the installation and other operations at the target site being affected by setting it on the back.
[0062] Furthermore, preferably, waterproof lead wire components 4 are provided on both sides of the junction box 3 along a direction perpendicular to the first direction a, for example, in this embodiment, the length direction of the main housing 1. Of course, it is not limited to this, and waterproof lead wire components 4 can also be provided on only one side of the junction box 3, depending on the actual needs.
[0063] In this embodiment, preferably, as follows: Figure 1 As shown, the battery box also includes a first mounting component 8 and a second mounting component 9; wherein, the first mounting component 8 is connected to the main box 1, the second mounting component 9 is connected to the first mounting component 8, and the second mounting component 9 can be connected to the target ground.
[0064] As can be seen from the structure described above, the second mounting component 9 can be fixed to the target location, such as a wall, and the first mounting component 8 can be fixed to the battery box. Then, the first mounting component 8 and the second mounting component 9 can be connected together to improve the convenience of operation.
[0065] In this embodiment, preferably, as follows: Figure 1 As shown, the first mounting component 8 includes a first mounting plate 81, a second mounting plate 82, and two side mounting plates 83. The second mounting plate 82 is connected to the first mounting plate 81 and is set at an obtuse angle. When the first mounting plate 81 is set vertically, the second mounting plate 82 is set at an inclination relative to the vertical direction. The two side mounting plates 83 are respectively set on opposite sides of the first mounting plate 81 along its length direction and are connected to both the first mounting plate 81 and the second mounting plate 82. The first mounting plate 81 is attached to the back panel of the main housing 1. The side mounting plates 83 are attached to the sides of the main housing 1 and are connected to the sides of the main housing 1 by a third fastening component 10.
[0066] The second mounting component 9 is a hollow shell structure with an opening facing the main housing 1. The second mounting plate 82 is attached to the upper surface of the top plate of the shell structure and extends along the top plate of the shell structure. It can be seen that the aforementioned second mounting plate 82 is inclined. Correspondingly, the top plate of the shell structure is also inclined. The side of the shell structure is attached to the side mounting plate 83, and the side of the shell structure and the side mounting plate 83 are detachably connected by the fourth fastening component 11.
[0067] As can be seen from the structure described above, the second mounting plate 82 of the first mounting component 8 can be directly placed on the top plate of the second mounting component 9, which improves the ease of assembly. Finally, the side of the second mounting component 9 and the side of the first mounting component 8 are fixed together by the fourth fastening component 11, such as screws or bolts. The operation is simple and convenient. Moreover, the second mounting component 9 supports the first mounting component 8, thereby supporting the battery box and making the battery box more stable.
[0068] Furthermore, preferably, the first mounting component 8 can be an integral structure and can be formed by bending, but of course, it is not limited to this.
[0069] Furthermore, preferably, the second mounting component 9 can be an integral structure and can be formed by bending, but of course, it is not limited to this.
[0070] In this embodiment, preferably, as follows: Figure 1 As shown, the waterproof lead wire component 4 can be a cable waterproof connector in the prior art, which has the functions of waterproofing and lead wire. Compared with the prior art of setting waterproof structures on electrical components such as connectors, it reduces costs. Of course, it is not limited to this and can be selected according to actual needs.
