[0040] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0041] In a first aspect, see Figure 1The embodiment of the present application provides a power supply box 100, which is used to accommodate a power supply device. The power supply device is used to access the power grid and convert the power supply of the power grid into the power required by the target power-consuming device.

[0042] For the power box 100, in some embodiments, see Figure 1 and Figure 2 The power box 100 includes a first plate 1, a second plate 2, a third plate 3 and a fourth plate 4. The second plate 2 is connected to the first plate 1, and the second plate 2 and the first plate 1 are arranged at an angle. For example, the first plate 1 and the second plate 2 form a "V" shape or a "factory" shape or other structure. The fourth plate 4 is connected to the third plate 3, and the fourth plate 4 and the third plate 3 are arranged at an angle. For example, the third plate 3 and the fourth plate 4 form a "V" shape or a "factory" shape or other structure. The third plate 3 is arranged at an angle to the first plate 1, and the third plate 3 is spaced apart from the second plate 2. For example, the first plate 1 and the third plate 3 form a "V" shape or a "factory" shape or other structure.

[0043] In some embodiments, the third plate body 3 is detachably connected to the first plate body 1. In an embodiment of the present application, the end of the fourth plate body 4 facing away from the third plate body 3 is detachably connected to the end of the second plate body 2 facing away from the first plate body 1, and the third plate body 3 is spaced apart from the second plate body 2, so the second plate body 2 and the fourth plate body 4 also form a "V" shape or "factory" shape or other structures.

[0044] In some embodiments, the angles between any two adjacent plates can be right angles. That is, the first plate 1, the second plate 2, the third plate 3, and the fourth plate 4 form a rectangular frame structure, which is conducive to installing square power supply components in the cavity formed therein.

[0045] The third plate 3 and the fourth plate 4 are detachably connected to the first plate 1 and the second plate 2. For example, see Figure 1 and Figure 2The first clamping piece 21 is arranged at one end of the second plate body 2 away from the first plate body 1, and the first matching part 421 is arranged at one end of the fourth plate body 4 away from the third plate body 3, and the first matching part 421 clamps the first clamping piece 21. That is, the second plate body 2 is buckled and connected with the fourth plate body 4. The third plate body 3 is provided with a connecting lug 31, and the power box 100 further comprises a fastener 5, which connects the connecting lug 31 and one end of the first plate body 1 away from the second plate body 2. That is, the third plate body 3 is detachably connected with the plate body through the fastener 5. In the embodiment of the application, the two connecting points between the whole formed by the first plate body 1 and the second plate body 2 and the whole formed by the third plate body 3 and the fourth plate body 4 are connected through the fastener 5 and the buckle respectively, which is beneficial to reducing the number of fasteners 5 and improving the disassembly efficiency of the power box 100 compared with the complete connection through the fastener 5, and is beneficial to improving the shaking problem of the third plate body 3 and the fourth plate body 4 relative to the first plate body 1 and the second plate body 2 and improving the reliability of the power box 100 compared with the complete connection through the buckle.

[0046] For the buckling connection of the first matching part 421 and the first clamping piece 21, see Figure 1 and Figure 2 The fourth plate body 4 comprises a first part 41 and a second part 42 connected with each other, the first part 41 is connected with the third plate body 3, the second part 42 is arranged at an angle with the first part 41, one side of the second part 42 away from the third plate body 3 abuts against the second plate body 2, and the second part 42 is provided with the first matching part 421. The first matching part 421 is provided with a clamping groove 4211 penetrating through the second part 42 along the first direction X, and the first clamping piece 21 is arranged in the clamping groove 4211. The first matching part 421 clamps the first clamping piece 21. Therefore, when the first clamping piece 21 is inserted into the clamping groove 4211 along the first direction X, it will be clamped by the first matching part 421, and then buckled and connected with the first matching part 421.

[0047] In some embodiments, see Figure 3 and Figure 4The first fitting part 421 comprises a first wall 4212 and a second wall 4213 of the clamping groove 4211, the first wall 4212 and the second wall 4213 are arranged at intervals along the second direction Y, and the first wall 4212 and the second wall 4213 clamp the first clamping piece 21. It can be understood that the clamping groove 4211 penetrates the second part 42 along the first direction X, and the clamping groove 4211 clamps the first clamping piece 21 along the second direction Y. In the embodiment of the present application, the clamping groove 4211 is provided with a notch at one end along the third direction Z, so that the depth direction of the clamping groove 4211 is parallel to the third direction Z, that is, the notch of the clamping groove 4211 points to the direction of the bottom of the clamping groove 4211 (the bottom in the direction of gravity). The arrangement makes the first clamping piece 21 not only be able to be inserted into the clamping groove 4211 along the first direction X, but also be able to be moved into the clamping groove 4211 along the third direction Z. For example, the first clamping piece 21 is first moved to the notch of the clamping groove 4211, and then moved into the clamping groove 4211 along the third direction Z.

[0048] It should be noted that in the embodiment of the present application, the first direction X, the second direction Y and the third direction Z are perpendicular to each other. In some other embodiments, the first direction X, the second direction Y and the third direction Z can also be acute or obtuse between each other, which is not limited here.

[0049] For clamping the first clamping piece 21 by the first wall 4212 and the second wall 4213, the present application provides two schemes:

[0050] Scheme one: please refer to Figure 3Along the second direction Y, the second wall 4213 includes a first surface 42131 and a second surface 42132 facing the first wall 4212. The first surface 42131 is perpendicular to the second direction Y, and the second surface 42132 is arranged at an angle to the first surface 42131. The first surface 42131 and the second surface 42132 are arranged in sequence along the third direction Z. The distance between the second surface 42132 and the first wall 4212 gradually decreases along the third direction Z. The first wall 4212 and the second surface 42132 clamp the first clamping member 21. It is understandable that when the first clamping member 21 is located between the first wall 4212 and the first surface 42131, the first wall 4212 and the first surface 42131 do not clamp the first clamping member 21. Then, the first clamping member 21 is moved along the third direction Z. As the distance between the first clamping member 21 and the second surface 42132 and / or the first wall 4212 gradually decreases, the first clamping member 21 is ultimately clamped between the first wall 4212 and the second surface 42132. By clamping the first clamping member 21 between the first wall 4212 and the second wall 4213 in this manner, the difficulty of clamping the first clamping member 21 between the first wall 4212 and the second wall 4213 can be reduced. For example, when the first clamping member 21 is forcefully inserted between the first wall 4212 and the second surface 42132 along the first direction X, the first clamping member 21 is difficult to be inserted between the first wall 4212 and the second surface 42132 along the first direction X because the first wall 4212 and the second surface 42132 have a greater clamping force on the first clamping member 21.

[0051] Option 2: Please refer to Figure 4 The first engaging portion 421 includes an elastic arm 4214, which includes a second wall 4213. The elastic arm 4214 applies an elastic force toward the first wall 4212 to the first clamping member 21. It is understood that the elastic arm 4214 clamps the first clamping member 21 through the second wall 4213 and the first wall 4212. This elastic force helps improve the clamping stability of the first clamping member 21.

[0052] It should be noted that Option 2 can be combined with Option 1. For example, the second wall 4213 of the elastic arm 4214 includes the above-mentioned first surface 42131 and second surface 42132. The elastic arm 4214 not only contacts the first clip 21 through the second surface 42132, but also contacts the first clip 21 through the part of the second wall 4213 other than the first surface 42131 and the second surface 42132 and applies an elastic force to the first clip 21.

[0053] For the above elastic arm 4214, see Figure 4The elastic arm 4214 has a protrusion 42141 on the side facing the first wall 4212. The protrusion 42141 is adjacent to the end of the elastic arm 4214 and includes at least a portion of the second wall 4213. When the protrusion 42141 includes the entire second wall 4213, the second wall 4213 does not include the first surface 42131 and the second surface 42132 of the first solution. This means that the second solution cannot be combined with the first solution. When the protrusion 42141 includes a portion of the second wall 4213, another portion of the second wall 4213 can include the first surface 42131 and the second surface 42132 of the first solution. This means that the second solution can be combined with the first solution. It is understandable that when the elastic arm 4214 is not provided with the protrusion 42141, the second wall 4213 on the elastic arm 4214 is planar, and the first wall 4212 is also planar. It is difficult for the planar first wall 4212 and the second wall 4213 to both contact the first clip 21. At least one of the first wall 4212 and the second wall 4213 can only contact the edge of the first clip 21, resulting in an unstable clamping of the first clip 21. By providing the protrusion 42141, the protrusion 42141 makes point contact or line contact with the first clip 21, and the first wall 4212 makes surface contact with the first clip 21, making the clamping of the first clip 21 more stable.

[0054] Furthermore, the provision of the protrusion 42141 facilitates the combination of the aforementioned solution 2 with the solution 1, i.e., the elastic arm 4214 not only contacts the first clip 21 via the second surface 42132, but also contacts the first clip 21 via the protrusion 42141 and applies an elastic force to the first clip 21. It is understood that the protrusion 42141, the first surface 42131, and the second surface 42132 are sequentially arranged along the third direction Z, or the protrusion 42141 and the second surface 42132 are sequentially arranged along the third direction Z.

[0055] In some embodiments, see Figure 4 The second wall 4213 of the protrusion 42141 includes a third surface 42133, and the first wall 4212 and the third surface 42133 clamp the first clamping member 21. In other words, the third surface 42133 is at least partially located on the protrusion 42141, and the protrusion 42141 contacts the first clamping member 21 through the third surface 42133. When the second solution is combined with the first solution, the second wall 4213 includes a first surface 42131, a second surface 42132, and a third surface 42133, and the second wall 4213 cooperates with the first wall 4212 to clamp the first clamping member 21 through the second surface 42132 and the third surface 42133. When the second solution is not combined with the first solution, the second wall 4213 includes a third surface 42133, and the second wall 4213 cooperates with the first wall 4212 to clamp the first clamping member 21 through the third surface 42133.

[0056] In some embodiments, see Figure 4The distance between the third surface 42133 and the first wall 4212 along the third direction Z decreases first and then increases. Thus, when the first clamping member 21 contacts the third surface 42133 during the movement of the first clamping member 21 relative to the second part 42 along the third direction Z, the elastic arm 4214 can be forced to bend towards the direction away from the first wall 4212, and thus the first clamping member 21 can be clamped between the first wall 4212 and the boss. Optionally, the third surface 42133 is a curved surface, such as an arc surface or a spherical surface.

[0057] For the first clamping member 21 described above, in some embodiments, referring to Figure 3 and Figure 4 the first clamping member 21 comprises a first segment 211 and a second segment 212 connected with each other, the first segment 211 extends along the first direction X, and the first segment 211 is clamped by the first fitting part 421, and the second segment 212 is arranged at an angle with the first segment 211. It can be understood that, when the first fitting part 421 clamps the first segment 211, the projection of the second segment 212 along the first direction X at least partially overlaps the second part 42, and thus the first clamping member 21 can be prevented from being pulled out of the clamping groove 4211 along the first direction X, and the connection between the first clamping member 21 and the first fitting part 421 is more reliable. Moreover, when the first clamping member 21 is located at the slot of the clamping groove 4211, the projection of the second segment 212 along the first direction X at least partially overlaps the second part 42, so that during the movement of the first clamping member 21 from the slot of the clamping groove 4211 to the inside of the clamping groove 4211 along the third direction Z, the first clamping member 21 is not easy to be pulled out of the clamping groove 4211 along the first direction X, and this is beneficial to reduce the difficulty of the movement of the first clamping member 21 from the slot of the clamping groove 4211 to the inside of the clamping groove 4211 along the third direction Z.

[0058] In some embodiments, the angle between the first segment 211 and the second segment 212 is a right angle.

[0059] In some embodiments, referring to Figure 3 and Figure 4The second portion 42 is provided with an avoiding hole 422 penetrating through the second portion 42 along the first direction X, the avoiding hole 422 being used for the second segment 212 to pass through the second portion 42 along the first direction X; the avoiding hole 422 is communicated with the clamping groove 4211, and the avoiding hole 422 is used for the first segment 211 to move to the clamping groove 4211. As viewed along the first direction X, the profile of the avoiding hole 422 is greater than the profile of the second segment 212, so that the second segment 212 can pass through the second portion 42 along the first direction X, and then the first segment 211 can be arranged in the avoiding hole 422, and then the first segment 211 can move in the avoiding hole 422 along a direction perpendicular to the first direction X, for example, to the opening of the clamping groove 4211, so that the first clamping piece 21 with the second segment 212 can still be clamped in the clamping groove 4211. It can be understood that the avoiding hole 422 and the clamping groove 4211 are arranged along the third direction Z, and the avoiding hole 422 is communicated with the clamping groove 4211.

[0060] In some embodiments, referring to Figure 5 The second portion 42 is provided with a plurality of first matching portions 421. This is advantageous to enhance the reliability of the buckle connection between the second plate body 2 and the fourth plate body 4. Among them, the structures of the plurality of first matching portions 421 can be different, for example, the second portion 42 is simultaneously provided with the first matching portion 421 of scheme one and the first matching portion 421 of scheme two.

[0061] In some embodiments, referring to Figure 5 The avoiding hole 422 penetrates to a side of the second portion 42 facing the second direction Y. Then the first clamping piece 21 can be directly moved into the avoiding hole 422 from the side of the second portion 42 facing the second direction Y.

[0062] In some embodiments, referring to Figure 1 and Figure 2 The first plate body 1 is provided with a second clamping piece 11 at an end away from the second plate body 2, and the third plate body 3 is provided with a second matching portion 32 at an end away from the fourth plate body 4. That is, the first plate body 1 and the third plate body 3 are also connected through buckle connection, further increasing the reliability of the connection between the first plate body 1 and the third plate body 3.

[0063] In some embodiments, the second clamping piece 11 is used for buckle connection with the second matching portion 32 along the opposite direction of the second direction Y, and the second clamping piece 11 is also used for movement relative to the second matching portion 32 along the third direction Z. Exemplarily, referring to Figure 1 , Figure 2 and Figure 5The second engaging portion 32 comprises a clamping groove 321 which is opened towards the second direction Y, and both ends of the clamping groove 321 penetrate the third plate body 3 along the third direction Z. The second clamping member 11 protrudes from other parts of the first plate body 1 towards the opposite direction of the second direction Y, and extends along the third direction Z. The second clamping member 11 is at least partially located in the clamping groove 321, so as to be connected with the second engaging portion 32. It should be understood that the clamping groove 321 which is opened towards the second direction Y means that the opening of the clamping groove 321 is towards the second direction Y. It should be understood that the second clamping member 11 can be inserted into the clamping groove 321 along the opposite direction of the second direction Y, and after being inserted into the clamping groove 321, the second clamping member 11 can move in the clamping groove 321 along the third direction Z. That is, the second clamping member 11 is used to be clamped and connected with the second engaging portion 32 along the opposite direction of the second direction Y, and the second clamping member 11 is also used to move along the third direction Z in the second clamping groove 4211.

[0064] In some embodiments, referring to Figure 1 and Figure 2 The clamping groove 321 is formed by punching and bending the edge of the third plate body 3. For example, the punched part is bent to form an angle steel shape, and the punched part and other parts of the third plate body 3 surround to form a clamping groove 321. It should be noted that in the clamping groove 321, there is no other groove wall corresponding to the bent part, so the length of the second clamping member 11 along the third direction Z is greater than the length of the punched part.

[0065] In some embodiments, referring to Figure 2 and Figure 3 One end of the second section 212 towards the second direction Y is connected with the first section 211. Therefore, the second section 212 can be first penetrated through the avoiding hole 422, and then the third plate body 3 and the fourth plate body 4 are moved relative to the first plate body 1 and the second plate body 2 along the second direction Y, so that the second clamping member 11 is inserted into the clamping groove 321 along the opposite direction of the second direction Y, and the second section 212 is simultaneously moved to the projection of the second section 212 along the first direction X at least partially overlaps with the second part 42, so as to reduce the difficulty of the first clamping member 21 moving from the notch of the clamping groove 4211 to the inside of the clamping groove 4211 along the third direction Z.

[0066] It can be understood that, in the embodiment, the difference between the width of the avoiding hole 422 and the thickness of the first section 211 is greater than or equal to the depth of the second clamping member 11 clamped to the second matching portion 32 along the second direction Y. In this way, when the distance of the first section 211 moving along the second direction Y in the avoiding hole 422 is greater than the depth of the second clamping member 11 clamped to the second matching portion 32, the first clamping member 21 can be inserted into the avoiding hole 422 first, and then the second clamping member 11 is inserted into the clamping groove 321 in the opposite direction of the second direction Y, and the first clamping member 21 moves in the opposite direction of the second direction Y in the avoiding hole 422, so that the problem that the second clamping member 11 is difficult to be inserted into the clamping groove 321 in the opposite direction of the second direction Y is avoided. The depth of the second clamping member 11 clamped to the second matching portion 32 refers to the depth of the second clamping member 11 inserted into the second matching portion 32 in the opposite direction of the second direction Y when the second clamping member 11 is clamped to the second matching portion 32.

[0067] For the above-mentioned fastener 5, the connecting lug 31 is connected to the end of the first plate body 1 away from the second plate body 2. For example, referring to Figure 2 , the first plate body 1 is provided with a first hole 12, and the connecting lug 31 is provided with a second hole 311. The fastener 5 passes through the second hole 311 and is inserted into the first hole 12, so as to connect the connecting lug 31 to the first plate body 1. The first hole 12 can be a threaded hole, and the fastener 5 can be a bolt. The second hole 311 is a through hole.

[0068] In some embodiments, referring to Figure 1 and Figure 2 , the connecting lug 31 is located on the side of the third plate body 3 facing the second plate body 2. That is, when viewed along the third direction Z, the connecting lug 31 is located between the first plate body 1, the second plate body 2, the third plate body 3 and the fourth plate body 4, which is beneficial to improve the problem that the fastener 5 and the connecting lug 31 protrude out of the third plate body 3 along the first direction X, and reduce the overall width of the power supply box 100 along the first direction X.

[0069] In some embodiments, referring to Figure 1 and Figure 2 , the distance between the connecting lug 31 and the first plate body 1 is less than the distance between the connecting lug 31 and the fourth plate body 4. That is, the connecting lug 31 is located at the end of the third plate body 3 adjacent to the first plate body 1. This is beneficial to shorten the problem that the fastener 5 protrudes out of the fourth plate body 4 in the opposite direction of the second direction Y. In the embodiment of the present application, the third plate body 3 and the fourth plate body 4 are part of the panel, so the problem that the fastener 5 protrudes out of the panel is improved.

[0070] In some embodiments, referring to Figure 5The third plate body 3 and the fourth plate body 4 are parallel to the third direction Z. The intersection line of the plane where the third plate body 3 is located and the plane where the fourth plate body 4 is located is parallel to the third direction Z. At least one end of the fourth plate body 4 is provided with a reinforcing portion 411 along the third direction Z. By providing the reinforcing portion 411, the bending strength of the fourth plate body 4 can be increased, which is beneficial to protect the power supply device in the power supply box 100. The reinforcing portion 411 can be specifically provided on the first portion 41. Similarly, in some embodiments, at least one end of the fourth plate body 4 is provided with a reinforcing portion (not shown) along the third direction Z.

[0071] In some embodiments, referring to Figure 5 The reinforcing portion 411 is formed by bending an edge of the fourth plate body 4. This is beneficial to reduce the processing cost of the reinforcing portion 411.

[0072] In the second aspect, referring to Figure 6 The power supply 200 has the structural features and beneficial effects of the power supply box 100, which will not be described here.

[0073] In some embodiments, referring to Figure 6 The fastener 5 passes through the second hole 311 and the power supply device 210 in sequence, and is then inserted into the first hole 12. Thus, the power supply device 210 is mounted on the first plate body 1, and one fastener 5 simultaneously connects the power supply device 210 and the connecting lug 31 to the first plate body 1, which is beneficial to reduce the number of fasteners 5 and improve the disassembly efficiency of the power supply.

[0074] In some embodiments, referring to Figure 6 The second portion 42 is provided with an avoiding gap 423 for avoiding the power supply device 210. It can be understood that the avoiding gap 423 is used to avoid the components on the power supply device 210 which abut against the second plate body 2. For example, an avoiding single tube is needed to abut against the second plate body 2 for heat dissipation due to a large amount of heat. By providing the avoiding gap 423, the problem of interference between the second portion 42 and the power supply device 210 can be improved.

[0075] The power supply box 100 and the power supply of the embodiments of the present application are beneficial to reduce the number of fasteners 5, improve the disassembly efficiency of the power supply box 100, and improve the problem of shaking of the third plate body 3 and the fourth plate body 4 relative to the first plate body 1 and the second plate body 2, and improve the reliability of the power supply box 100.

[0076] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; under the idea of the present application, the technical features in the above examples or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for simplicity; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
