[0001] The invention relates to the technical field of circuit boards, and in particular to an electric control box. Background Art

[0002] Circuit board, also known as printed circuit board or printed circuit board, mainly makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. As more and more products tend to be miniaturized and intelligent, even the originally large circuits can now be realized with a circuit board. For intelligent systems, people usually put multiple circuit boards in the electric control box. The purpose of this is to operate conveniently and quickly once the circuit board is damaged or needs to be replaced.

[0003] However, the circuit board is usually fixed in the electric control box by screw connection, and multiple circuit boards are arranged in the electric control box in a flat or stacked manner. If multiple circuit boards are arranged in the electric control box in a flat manner, they will occupy a larger space of the electric control box, which greatly wastes the use space inside the chassis. Therefore, at present, multiple circuit boards are mostly arranged in the electric control box in a stacked manner. However, when a circuit board fails or is damaged and needs to be replaced or repaired, the circuit boards above it must be removed in turn, resulting in a longer replacement or repair time and significantly increased labor intensity.

[0036] The technical solution provided by the embodiments of the present invention is described below in conjunction with the accompanying drawings.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides an electric control box 100, which includes a housing 110 and at least one mounting plate 120. The electric control box 100 is used for packaging a single or multiple circuit boards.

[0038] The housing 110 has a first side wall 111 and a second side wall 112, and the first side wall 111 and the second side wall 112 are arranged opposite to each other, that is, the first side wall 111 and the second side wall 112 have opposite surfaces, and there is a gap between the first side wall 111 and the second side wall 112. At least one fixing assembly 113 is arranged on the housing 110, and one fixing assembly 113 includes two fixing parts 1131, one of the two fixing parts 1131 is located on the first side wall 111, and the other one of the fixing parts 1131 is located on the second side wall 112. In other words, when there is only one fixing assembly 113, there is one fixing portion 1131 on the first side wall 111, and there is also one fixing portion 1131 on the second side wall 112; when there are multiple fixing assemblies 113, there are multiple fixing portions 1131 on the first side wall 111, and there are also multiple fixing portions 1131 on the second side wall 112, and the number of fixing portions 1131 on the first side wall 111 and the second side wall 112 is the same. The fixing portion 1131 includes a first clamping portion 1132 and a clamping groove 1133.

[0039] The mounting plate 120 can be used to accommodate or place the circuit board to fix the circuit board and package the circuit board in the electric control box 100. The mounting plate 120 is provided with a second clamping portion 121 and a rotating shaft 122, wherein the second clamping portion 121 can cooperate with the first clamping portion 1132, the rotating shaft 122 can be clamped in the clamping groove 1133, and the rotating shaft 122 can rotate relative to the clamping groove 1133. When the first clamping portion 1132 cooperates with the second clamping portion 121, and the rotating shaft 122 is clamped in the clamping groove 1133, the mounting plate 120 can be fixed on the fixing portion 1131 to achieve the connection between the mounting plate 120 and the housing 110, which is convenient for loading the circuit board; when the matching relationship between the first clamping portion 1132 and the second clamping portion 121 is released, and the rotating shaft 122 is rotated in the clamping groove 1133, the mounting plate 120 can be disassembled, which is convenient for replacing or repairing the circuit board.

[0040] In the above-mentioned electric control box 100, a second clamping portion 121 matched with the first clamping portion 1132 is provided on the mounting plate 120, and a rotating shaft 122 rotatably clamped in the clamping groove 1133 is also provided on the mounting plate 120. When the first clamping portion 1132 cooperates with the second clamping portion 121 and the rotating shaft 122 is clamped in the clamping groove 1133, the mounting plate 120 can be fixed on the fixing assembly 113, that is, the mounting plate 120 can be fixed on the two fixing portions 1131 to achieve the connection between the mounting plate 120 and the housing 110, which is convenient for loading the circuit board; when the matching relationship between the first clamping portion 1132 and the second clamping portion 121 is released, and the rotating shaft 122 is rotated in the clamping groove 1133, the mounting plate 120 can be disassembled, which is convenient for replacing or repairing the circuit board, and can prevent the circuit board from being damaged during the assembly and disassembly process, thereby significantly reducing the labor intensity.

[0041] In order to further improve the replacement or maintenance efficiency of the circuit board, a preferred implementation is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the first side wall 111 has a first direction ( Figure 1 V direction) and the second direction ( Figure 1 The first direction and the second direction are located on the surfaces opposite to the first side wall 111 and the second side wall 112, and the first direction is the stacking direction of the plurality of circuit boards, that is, the first direction is Figure 1In the height direction of the electric control box 100, the first direction is perpendicular to the second direction. The first side wall 111 and the second side wall 112 both have a first surface 114 and a second surface 115, the first surface 114 and the second surface 115 are opposite to each other, and in the second direction, the first surface 114 and the second surface 115 are respectively located on both sides of the first side wall 111 or the second side wall 112. In other words, the first side wall 111 has a first surface 114 and a second surface 115, and in the second direction, the first surface 114 and the second surface 115 are respectively located on both sides of the first side wall 111; similarly, the second side wall 112 has a first surface 114 and a second surface 115, and in the second direction, the first surface 114 and the second surface 115 are respectively located on both sides of the second side wall 112.

[0042] There are multiple fixing components 113, and multiple fixing parts 1131 are sequentially arranged along the first direction. It should be noted that when there are multiple fixing components 113, there are multiple fixing parts 1131 on the first side wall 111, and there are also multiple fixing parts 1131 on the second side wall 112, and the number of fixing parts 1131 on the first side wall 111 and the second side wall 112 is the same, so as to ensure that multiple mounting plates 120 can be fixed to the housing 110 through multiple fixing components 113, and multiple circuit boards are indirectly packaged in the electric control box 100. In addition, there are gaps between the multiple fixing parts 1131 on the first side wall 111, and similarly, there are gaps between the multiple fixing parts 1131 on the second side wall 112.

[0043] The engaging groove 1133 is L-shaped, and in the thickness direction of the first side wall 111, the engaging groove 1133 passes through the first side wall 111 and the second side wall 112, that is, the engaging groove 1133 on the first side wall 111 passes through the first side wall 111, and the engaging groove 1133 on the second side wall 112 passes through the second side wall 112. The engaging groove 1133 includes a first groove section 1134, a second groove section 1135 and a through hole 1136, and the first groove section 1134, the second groove section 1135 and the through hole 1136 are connected to each other, and the rotating shaft 122 is rotatably engaged in the through hole 1136. In this embodiment, as Figure 2As shown, the first slot section 1134 extends a certain length along the second direction, and the second slot section 1135 extends a certain length along the first direction. Of course, in other embodiments, the first slot section 1134 and the second slot section 1135 are not limited to the above-mentioned arrangement, and the present invention does not limit the specific extension direction of the first slot section 1134 and the second slot section 1135. The first slot section 1134 in one of the two adjacent fixing components 113 opens on the first surface 114, and the first slot section 1134 in the other of the two adjacent fixing components 113 opens on the second surface 115, so as to ensure that when the matching relationship between the first clamping portion 1132 and the second clamping portion 121 is released, by rotating the rotating shaft 122, the mounting plate 120 can slide out to the outside of the housing 110 through the through hole 1136, the second slot section 1135, and the first slot section 1134 in sequence under the action of force, so as to realize the disassembly of the circuit board. For example, two adjacent fixing portions 1131 in the first side wall 111, both of the two adjacent fixing portions 1131 have a first slot section 1134, one of the two adjacent first slot sections 1134 opens on the first surface 114 on the first side wall 111, and the other of the two adjacent first slot sections 1134 opens on the second surface 115 on the first side wall 111; similarly, two adjacent fixing portions 1131 in the second side wall 112, both of the two adjacent fixing portions 1131 also have a first slot section 1134, one of the two adjacent first slot sections 1134 opens on the first surface 114 on the second side wall 112, and the other of the two adjacent first slot sections 1134 opens on the second surface 115 on the second side wall 112.

[0044] In order to further improve the stability of fixing the mounting plate 120 on the housing 110, specifically, as Figure 1 , Figure 2 and Figure 3 As shown, along the second direction, the first clamping portion 1132 and the clamping groove 1133 in the fixing portion 1131 are respectively located at the two ends of the corresponding first side wall 111 and the second side wall 112. In other words, in a single fixing portion 1131 on the first side wall 111, along the second direction, the first clamping portion 1132 and the clamping groove 1133 are respectively corresponding to the two ends of the first side wall 111; similarly, in a single fixing portion 1131 on the second side wall 112, along the second direction, the first clamping portion 1132 and the clamping groove 1133 are respectively corresponding to the two ends of the first side wall 111.

[0045] In the above-mentioned electric control box 100, the distance between the first clamping portion 1132 and the clamping groove 1133 is relatively far. When the first clamping portion 1132 cooperates with the second clamping portion 121 and the rotating shaft 122 is clamped in the clamping groove 1133, the forces on both ends of the mounting plate 120 tend to be consistent, which can prevent the mounting plate 120 from being damaged such as breakage due to the vibration of the suspended end of the mounting plate 120 during transportation or movement, and can improve the stability of the mounting plate 120 fixed on the shell 110, thereby increasing the stability of the circuit board, and preventing the circuit board from short-circuiting or failing due to frequent vibration of the mounting plate 120, thereby causing greater economic losses to users.

[0046] In order to facilitate the disassembly of the mounting plate 120, specifically, as Figure 1 , Figure 2 and Figure 3 As shown, the shaft 122 is a D-shaped shaft, and the shaft 122 protrudes from the side of the mounting plate 120, and the groove width of the second groove section 1135 ( Figure 3 W) is greater than the sum of the distance from the plane of the D-shaped shaft along its axial direction to its axis and the radius of the D-shaped shaft ( Figure 3 L), and the groove width of the second groove section 1135 is smaller than the diameter of the D-shaped shaft ( Figure 3 D), that is, L<W<D, to ensure that when the rotating shaft 122 rotates in the engaging groove 1133, there is a position where the rotating shaft 122 can slide from the second groove section 1135 under the action of force, so that the rotating shaft 122 can be separated from the engaging groove 1133, which is convenient for disassembly of the mounting plate 120. It should be noted that the groove width of the first groove section 1134 is greater than the sum of the distance between the plane of the D-shaped shaft along its axial direction and its axis and the radius of the D-shaped shaft, so as to ensure that the rotating shaft 122 can be separated from the open end of the first groove section 1134, and prevent the rotating shaft 122 from being stuck during the separation process.

[0047] Furthermore, if Figure 1 , Figure 2 and Figure 3 As shown, when the rotating shaft 122 is engaged in the engaging groove 1133, the plane of the D-shaped shaft along its axial direction is parallel to the plane of the mounting plate 120 accommodating the circuit board, and in the first direction, the first groove section 1134 is located below the through hole 1136. During the rotation of the rotating shaft 122, the rotating shaft 122 can be separated from the through hole 1136 under the action of gravity, and then slide out of the housing 110 along the second groove section 1135 and the first groove section 1134 in sequence, so as to facilitate the disassembly of the mounting plate 120.

[0048] Specifically, Figure 4 and Figure 5As shown, when only one circuit board is encapsulated in the electric control box 100, the mounting plate 120 is rotated, that is, the shaft 122 rotates in the engaging groove 1133. When the mounting plate 120 is rotated to a substantially vertical state, the shaft 122 slides out of the through hole 1136 under the action of gravity or the external force of the operator, and passes through the second groove section 1135 and the first groove section 1134 in sequence, so that the mounting plate 120 is separated from the housing 110, and the disassembly operation of the mounting plate 120 is completed, and the circuit board is replaced or repaired. Figure 6 As shown, when there are multiple circuit boards encapsulated in the electric control box 100, in order to facilitate the explanation of the rotation process of each mounting plate 120, the mounting plate 120 where the circuit board to be replaced or repaired is located is referred to as a specific mounting plate 120, and the mounting plate 120 above the specific mounting plate 120 is referred to as an upper mounting plate 120. When one of the multiple circuit boards needs to be replaced or repaired, the upper mounting plate 120 is rotated 180°, that is, the upper mounting plate 120 is in a substantially horizontal state; and the specific mounting plate 120 is rotated 90°, that is, the specific mounting plate 120 is substantially in a vertical state. Under the action of gravity or the external force of the operator, the rotating shaft 122 in the specific mounting plate 120 slides out of the through hole 1136 and passes through the second slot section 1135 and the first slot section 1134 in sequence, so that the specific mounting plate 120 is separated from the housing 110, and the disassembly operation of the specific mounting plate 120 is completed, and the circuit board is replaced or repaired. When a plurality of circuit boards are encapsulated in the above-mentioned electric control box 100, when replacing or repairing one of the plurality of circuit boards, it is not necessary to completely remove the upper mounting plate 120, and the disassembly operation of the specific mounting plate 120 can be completed. The disassembly is simple and can prevent the mounting plate 120 from being damaged during repeated disassembly, thereby significantly reducing the labor intensity of replacing or repairing the circuit boards.

[0049] In order to achieve the cooperation between the first clamping portion 1132 and the second clamping portion 121, a preferred implementation is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the first clamping portion 1132 is a clamping groove, and the first clamping portion 1132 protrudes from the first side wall 111 and the second side wall 112 correspondingly, that is, the first clamping portion 1132 on the first side wall 111 protrudes from the first side wall 111; the first clamping portion 1132 on the second side wall 112 protrudes from the second side wall 112. The second clamping portion 121 is a hook, and the hook is provided on the mounting plate 120 by welding, screwing, etc. Through the cooperation of the hook and the clamping groove, the cooperation between the first clamping portion 1132 and the second clamping portion 121 can be achieved, and the mounting plate 120 can be fixed on the housing 110.

[0050] In order to facilitate the unlocking between the mounting plate 120 and the housing 110, specifically, as Figure 1 , Figure 2 and Figure 3 As shown, the hook is rotatably arranged on the mounting plate 120 by means of a pin shaft or the like. When the user presses the end of the hook away from the card slot, due to the lever effect, the end of the hook close to the card slot (i.e., the part where the hook and the card slot are engaged) is separated from the card slot, which facilitates unlocking between the mounting plate 120 and the housing 110.

[0051] In order to facilitate the replacement and maintenance of the circuit board, a preferred implementation is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the circuit board is detachably connected to the mounting plate 120. When the circuit board is damaged, the circuit board on the mounting plate 120 can be directly removed, and the circuit board can be replaced and repaired. This prevents the entire electric control box 100 from needing to be replaced when the circuit board is damaged and fails, so that the product can be used normally, which brings a bad experience to the user.

[0052] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, a mounting hole is provided on the mounting plate 120, and screws are inserted into the mounting plate 120. First, the circuit board is accommodated or placed on the mounting plate 120, and the mounting position on the circuit board is aligned with the mounting hole, and screws are inserted into the mounting hole, so that the circuit board is detachably connected to the mounting plate 120 by screw connection. Of course, the connection method between the circuit board and the mounting plate 120 is not limited to the screw connection method provided above, and can also be a clamping connection, an embedding method, etc. The present invention does not limit the specific connection method between the circuit board and the mounting plate 120.

[0053] In addition, if Figure 1 , Figure 2 , Figure 3 As shown, the electric control box 100 further includes a connecting frame 116, which is arranged on the housing 110 by screwing, welding, etc., and the electric control box 100 can be fixedly connected to other devices through the connecting frame 116. In this embodiment, the connecting frame 116 is preferably fixed to other devices by screwing, so as to fix the electric control box 100 to other devices.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
