[0028] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] Based on this, the present embodiment provides a distribution box, by arranging a mounting seat 12 for mounting and fixing the circuit board 2 on the outer wall of the shell 11, so that the circuit board 2 can be placed outside, without interfering with the internal space of the distribution box, and can further optimize the internal layout of the distribution box; at the same time, the circuit board 2 can be arranged to fit on the outer wall of the shell 11, thereby reducing the impact of arranging the circuit board 2 outside the shell 11 of the distribution box on the overall size of the distribution box. The following is a detailed description of this through specific embodiments:

[0031] Reference Figures 1 to 3 As shown, a distribution box provided in this embodiment includes: a shell 11 and a mounting base 12 arranged on the outer wall of the shell 11; a mounting portion 121 for fixing the circuit board 2 is provided on the mounting base 12; the protruding end of the mounting portion 121 is coplanar with the outer edge of the shell 11, or is located on the inner side of the outer edge of the shell 11, and the protruding end of the mounting portion 121 refers to an end of the mounting portion 121 extending toward a side away from the shell 11, wherein the circuit board 2 is a high-voltage collection board; specifically, the circuit board 2 can be connected to the mounting portion 121 by bonding, welding, bolting, riveting, etc.

[0032] The distribution box provided in this embodiment, by arranging a mounting seat 12 for mounting and fixing the circuit board 2 on the outer wall of the shell 11, the circuit board 2 can be placed outside without interfering with the internal space of the distribution box, and the internal layout of the distribution box can be further optimized; at the same time, the circuit board 2 can be arranged to fit on the outer side wall of the shell 11, so as to avoid the influence of arranging the circuit board 2 outside the shell 11 of the distribution box on the overall size of the distribution box.

[0033] In some embodiments, continue to refer to Figures 1 to 3 As shown, a wire hole 111 is opened on the shell 11, and the wire hole 111 is used for the connection wires on the circuit board 2 to pass through; specifically, the wire hole 111 can be opened on the side wall corresponding to the circuit board 2, and the connection wires on the circuit board 2 can directly pass through the corresponding wire hole 111 to enter the interior of the distribution box, and be electrically connected to the designated electrical components inside; wherein, the number of wire holes 111 can be one or more, as long as all the connection wires on the circuit board 2 that need to be connected to the interior of the distribution box can pass through, so that the circuit board 2 and the electrical components inside the distribution box can be electrically connected.

[0034] In some embodiments, the distribution box also includes a protective cover 13, which can be removably installed on the shell 11 or the mounting base 12 to cover at least part of the circuit board 2; it should be understood that the protective cover 13 can be buckled on the outer wall of the shell 11, and together with the outer wall of the shell 11 form a protective space for protecting the circuit board 2; through the setting of the protective cover 13, a protective space specifically for protecting the circuit board 2 and the connecting wires of the circuit board 2 can be formed outside the shell 11.

[0035] Furthermore, the protective cover 13 includes two baffles 131 which are parallel to each other and arranged opposite to each other. The baffles 131 are arranged perpendicular to the outer wall of the shell 11. The mounting seat 12 is located between the two baffles 131. The two baffles 131 extend toward the side away from the outer wall of the shell 11, and the outer edges of the two baffles 131 are coplanar with the outer edge of the shell 11, or are located on the inner side of the outer edge of the shell 11; wherein, four baffles 131 can also be provided, and each two of the four baffles 131 are arranged opposite to each other, so as to protect the mounting seat 12 on all sides.

[0036] Continue to refer to Figure 1 and Figure 2 As shown, the baffle 131 may be provided with a bending reinforcement portion 1311, wherein the bending reinforcement portion 1311 forms an angle with the baffle 131, thereby enhancing the connection stability between the baffle 131 and the shell 11, and also enhancing the structural strength of the baffle 131 itself. The head end and the tail end of the two baffles 131 may be provided with a bending reinforcement portion 1311 bent toward the other baffle 131, and the four bending reinforcement portions 1311 may be snap-fitted with the four top corners of the circuit board 2, thereby utilizing the four bending reinforcement portions 1311 to limit the four angles of the circuit board 2, thereby improving the installation stability of the circuit board 2.

[0037] Continue to refer to Figure 1 As shown, the protective cover 13 also includes a blocking cover 132, which is arranged parallel to the outer wall of the shell 11. The blocking cover 132 can be detachably mounted on the two baffles 131, and is surrounded by the two baffles 131 to form a chamber for protecting the circuit board 2; wherein the blocking cover 132 can be connected to the baffle 131 by means of snap connection, bolt connection, magnetic connection, etc., so as to form a chamber for protecting the circuit board 2.

[0038] Continue to refer to Figure 3As shown, a flange structure is provided on the outer wall of the shell 11, and the flange structure forms a mounting seat 12. A mounting portion 121 is provided on the flange structure. The outer edge of the flange structure is coplanar with the outer edge of the shell 11, or is located on the inner side of the outer edge of the shell 11, so as to avoid the circuit board 2 being arranged outside the shell 11 of the distribution box and affecting the overall size of the distribution box; wherein, the flange structure can be a plate-like structure perpendicular to the outer wall of the shell 11, formed by partially folding the outer wall of the shell 11; the flange structure extends outward to form a mounting seat 12 for mounting the circuit board 2, and the flange structure can specifically be processed with a buckle, a groove, or a threaded seat welded or bonded to form the mounting portion 121.

[0039] It is understandable that the flange structure can be formed by machining a U-shaped gap on the outer wall of the shell 11, and then pushing the solid structure inside the U-shaped gap outward from the inside of the shell 11 to form the flange structure.

[0040] In a further embodiment, there are two groups of flange structures, which are arranged opposite to each other and together form a mounting seat 12, and the two groups of flange structures are used to accommodate the circuit board 2; one group of flange structures is provided with at least one mounting portion 121, and the other group of flange structures is provided with at least two mounting portions 121; such an arrangement can further improve the stability of the circuit board 2 on the mounting seat 12, and the cooperation of at least three mounting portions 121 can provide reliable and stable multi-point support for the circuit board 2, thereby preventing the circuit board 2 from being folded, rotated, or otherwise unfixed on the outside of the shell 11; specifically, the two relatively arranged flange structures can be formed by machining an H-shaped gap on the outer wall of the shell 11, and then ejecting the solid structure inside the H-shaped gap from the inside of the shell 11 to the outside, so as to form two relatively arranged flange structures.

[0041] The lock 311 of the second end of the locking nut 31 is used to lock the locking nut 32 with the hook 31. The lock 311 of the second end of the locking nut 31 is used to lock the locking nut 32 with the hook 31. When the locking nut 31 is unlocked, the locking nut 32 is unlocked. When the locking nut 31 is unlocked, the locking nut 32 is unlocked. When the locking nut 31 is unlocked, the locking nut 32 is unlocked.

[0042] Specifically, each flange structure is provided with two mounting portions 121 , and the four mounting portions 121 are respectively located at the four vertex corners of the circuit board 2 , so as to fix the circuit board 2 .

[0043] In some embodiments, a bending portion 122 is provided on the flange structure, and the bending portion 122 forms an angle with the flange structure; the bending portion 122 can be specifically cut and separated at the connection between the flange structure and the outer wall of the shell 11 to form a free end, and then the free end is bent to form the bending portion 122. The bending portion 122 can specifically be a straight plate structure perpendicular to the flange structure, or a folded plate structure with multiple sections of bending; thereby, it can play a role in supporting the flange structure and prevent the flange structure from continuing to flip over with the outer wall of the shell 11 along the original crease; it can also further improve the stability and reliability of the circuit board 2 on the mounting base 12.

[0044] Continue to refer to Figure 3 As shown, the mounting portion 121 is arranged at the bending portion 122; when the mounting portion 121 is a threaded seat, the side wall of part of the bending portion 122 can be welded or bonded to the side wall of the mounting portion 121. By setting the bending portion 122, the contact area with the mounting portion 121 can be increased, thereby improving the stability and reliability of the mounting portion 121 and reducing the probability of the mounting portion 121 falling off the mounting seat 12.

[0045] Furthermore, the head end and the tail end of the two flange structures can be provided with a bending portion 122 bent toward the other flange structure, and the four bending portions 122 can be engaged with the four top corners of the circuit board 2, so that the four bending portions 122 are used to limit the four angles of the circuit board 2, thereby improving the installation stability of the circuit board 2.

[0046] In some embodiments, a wire hole 111 is formed on the side wall of the shell 11 at a position for forming a flange structure; it should be understood that the flange structure is a part of the side wall structure of the shell 11, and when it is folded to an angle perpendicular to the side wall of the shell 11, a through hole connected to the interior of the shell 11 is formed on the side wall of the shell 11, and the through hole can be used as a wire hole 111 for passing the connecting wire on the circuit board 2.

[0047] In a second aspect, the present application provides a power distribution device, comprising the power distribution box as described above.

[0048] The power distribution device can realize the external placement of the circuit board 2 by using the distribution box, so that the circuit board 2 does not interfere with the internal space of the distribution box, and the internal layout of the distribution box can be further optimized; at the same time, the circuit board 2 can be arranged to fit on the outer wall of the shell 11, so as to avoid the influence of the overall size of the distribution box on the circuit board 2 being arranged outside the shell 11 of the distribution box; the power distribution device can use the mounting seat 12 to install other circuit boards 2 except the high-voltage acquisition board.

[0049] In a third aspect, the present application provides an electric control system, comprising the power distribution box as described above, or comprising the power distribution device as described above.

[0050] The electric control system can realize the external placement of the circuit board 2 by using the distribution box, so that the circuit board 2 does not interfere with the internal space of the distribution box, and the internal layout of the distribution box can be further optimized; at the same time, the circuit board 2 can be arranged to fit on the outer wall of the shell 11, so as to avoid the influence of the overall size of the distribution box on the circuit board 2 being arranged outside the shell 11 of the distribution box; the electric control system can use the mounting seat 12 to install other circuit boards 2 except the high-voltage acquisition board.
