Detailed Description

In the related art, a circuit board in an electronic control box is generally supported and connected to a box wall of a box body through a support column, and a connection area between the support column and the box wall of the box body is small, that is, a support area of the box wall for the support column is small, so that when the electronic control box encounters an impact or a fall, the connection between the support column and the box wall is prone to failure, and the installation reliability of the circuit board is poor.

In view of this, in the embodiment of the present invention, the mounting plate fixing member includes the connecting column and the supporting base, and the supporting base with a larger horizontal size is disposed between the connecting column and the bottom wall, so as to increase the range of the supporting area of the bottom wall of the box body to the mounting plate fixing member, which makes the mounting plate fixing member support the mounting plate more stably, and also makes the electrical control box have better drop resistance.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 and 2 are schematic exploded views of the electrical control box 100 according to the present invention, and it should be noted that in the drawings of the present invention, the top side of the electrical control box 100 is shown in the positive direction of the Z axis, and the bottom side of the electrical control box 100 is shown in the negative direction of the Z axis. The right side of the electrical control box 100 is shown in the positive X-axis direction, and the left side of the electrical control box 100 is shown in the negative X-axis direction. The front side of the electrical control box 100 is represented by the positive direction of the Y-axis, and the rear side of the electrical control box 100 is represented by the negative direction of the Y-axis.

Referring to fig. 1 and 2, the electronic control box 100 may include a box body 110 having an accommodating cavity therein, where the box body 110 includes a lower box body 112 and a box cover 111, and the lower box body 112 and the box cover 111 together enclose the accommodating cavity. The lower case 112 may include a bottom wall 1121 and a side wall 1122 attached around the bottom wall 1121. The bottom wall 1121, the side wall 1122, and the cover 111 may collectively define a receiving cavity.

The electronic control box 100 may be, for example, a sealed electronic control box 100. Therefore, other foreign matters such as water drops and dust can be prevented from entering the electric control box 100 to damage electronic elements in the electric control box 100, and the waterproof, dustproof and anticorrosion effects are achieved.

The electrical control box 100 may further include a mounting plate assembly 120 and a circuit board (not shown) or the like located in the receiving cavity. Where mounting plate assembly 120 may include a mounting plate 130 and a plurality of mounting plate mounts 150, a circuit board may be disposed on mounting plate 130, e.g., the circuit board may be secured to mounting plate 130 by fasteners or the like. Mounting plate mount 150 is used to secure mounting plate 130 to bottom wall 1121.

It can be understood that, in the above-mentioned scheme, the case of arranging components such as a circuit board in the electronic control box 100 is exemplified, but the embodiment of the present invention is not limited thereto, and in practice, components such as the refrigerant heat dissipation unit 140 may also be arranged in the electronic control box 100 according to requirements, and at this time, the refrigerant heat dissipation unit 140 may also be arranged on the mounting plate 130.

The structure of each part in the electronic control box 100 will be described in detail below with reference to the accompanying drawings.

Fig. 3 is a partial enlarged view of a portion a in fig. 2, and referring to fig. 2 and 3, the mounting plate fixing member 150 includes a support base 151 and a connection column 152, the support base 151 is connected to the bottom wall 1121, the connection column 152 is connected to the top end of the support base 151, and the mounting plate 130 can be connected to the connection column 152, which is equivalent to the mounting plate 130 being supported and fixed on the bottom wall 1121 by the connection column 152 and the support base 151.

In addition, it is also necessary to make the projection of the supporting base 151 on the bottom wall 1121 cover the projection of the connecting column 152 on the bottom wall 1121, in other words, make the horizontal contour dimension (contour along XY plane) of the supporting base 151 greater than the horizontal contour dimension of the connecting column 152, so as to actually increase the arrangement range of the supporting points of the bottom wall 1121 on the mounting board fixture 150, compared with the prior art that the connecting column is used alone to support the mounting board 130 on the bottom wall 1121, not only the connection between the bottom wall 1121 and the mounting board fixture 150 is not easy to fail, but also the supporting performance of the mounting board fixture 150 on the mounting board 130 is improved, so that the drop-resistant performance of the electronic control box 100 is better.

In more detail, the points on the bottom wall 1121 that contact the mounting plate fixture 150 are used as support points, and these points may be referred to as support points, in the prior art, in the solution that only connects the post to support the mounting plate 130, the points on the bottom wall 1121 that contact the bottom of the post 152 are used as support points, and the arrangement range of these support points is limited within the range of the bottom end surface of the post 152. In the present application, the connecting column 152 is supported on the supporting base 151, the supporting base 151 is supported on the bottom wall 1121, all the points of the bottom wall 1121 contacting with the supporting base 151 are supporting points, and the layout range of the supporting points can be distributed in the range of the bottom end surface of the supporting base 151. The projection of the supporting base 151 on the bottom wall 1121 covers the projection of the connecting column 152 on the bottom wall 1121, and the layout range of the supporting points of the bottom wall 1121 for supporting the supporting base 151 is larger than that of the supporting points when the bottom wall 1121 alone supports the connecting column 152, so that the mounting plate 130 is better supported by the mounting plate fixing member 150.

The projection of the supporting base 151 on the bottom wall 1121 mentioned in the above-mentioned scheme covers the projection of the connecting column 152 on the bottom wall 1121, which not only means that the area of the projection of the supporting base 151 on the bottom wall 1121 is larger than the area of the projection of the connecting column 152 on the bottom wall 1121, but also means that the projection of the connecting column 152 on the bottom wall 1121 needs to be within the range of the projection of the supporting base 151 on the bottom wall 1121, so that the center of gravity of the connecting column 152 can be within the supporting range of the supporting base 151, and the supporting effect of the mounting plate fixing member 150 on the mounting plate 130 is better. Of course, the number of the mounting plate fixing members 150 may be provided in plurality to more stably support the mounting plate.

Wherein the connection column 152 may be connected to the top end of the support base 151 by welding, and the mounting plate 130 may be mounted on the connection column 152 by screwing. For example, the attachment post 152 may be provided with an internally threaded hole, and a fastener, such as a screw, may be threaded through the mounting plate 130 and into the internally threaded hole to connect the mounting plate 130 to the attachment post 152.

Referring to fig. 3, the supporting base 151 may include a main body portion 1511 and two mounting portions 1512 connected to two opposite sides of the main body portion 1511, and by disposing the two mounting portions 1512 on opposite sides of the main body portion 1511, the projection range of the supporting base 151 on the bottom wall 1121 may be wider, so that the layout range of the supporting points where the bottom wall 1121 supports the supporting base 151 may be wider, and the mounting portions 1512 and the main body portion 1511 may have a better supporting effect on the mounting plate 130.

In the above solution, the mounting portion 1512 may be connected to the bottom wall 1121, and the main body portion 1511 and the bottom wall 1121 have a gap therebetween, and the connection post 152 may be fixed on the main body portion 1511.

It can be understood that, because the main body 1511 is suspended under the support of the two mounting portions 1512, when the electronic control box 100 is impacted or falls, and the mounting plate 130 presses the connecting post 152 to move toward the bottom wall 1121, the main body 1511 can be forced to move toward the bottom wall 1121 to deform the supporting base 151, and this deformation can buffer a portion of the impact force applied to the electronic control box 100, thereby preventing the mounting plate fixing member 150 from separating from the bottom wall 1121, and further improving the mounting reliability of the mounting plate 130.

Here, the material of the supporting base 151 may be a metal material with better toughness, and the supporting base 151 may be connected to the bottom wall 1121 by welding, for example. Alternatively, as shown in fig. 3, the mounting portions 1512 may be fixed to the bottom wall 1121 by providing mounting holes in each of the two mounting portions 1512 and fixing fasteners to the bottom wall 1211 through the mounting holes.

Of course, whether the mounting portion 1512 is connected to the bottom wall 1121 by welding or fastening, it is considered that the bottom portions of the two mounting portions 1512 are attached to the bottom wall 1121, for example, the bottom end surfaces of the two mounting portions 1512 are both surfaces matched with the top end surface of the bottom wall 1121, so that when the mounting portion 1512 is supported on the bottom wall 1121, the supporting base 151 and the bottom wall 1121 have a larger contact area.

In an embodiment of the present invention, the same supporting base 151 may include two mounting portions 1512 and two connecting posts 152, wherein the two mounting portions 1512 are symmetrically disposed with respect to the connecting posts 152. Therefore, the two mounting portions 1512 are stressed uniformly, the supporting performance of the main body portion 1511 is better, and meanwhile, the connection between the two mounting portions 1512 and the bottom wall 1121 is not prone to failure.

In the embodiment of the present invention, the box body 110 is generally made of metal, and the box body 110 may be a sheet metal part, such as the bottom wall 1121, which is easy to deform under the action of an impact force when the electronic control box is impacted or falls off due to a large area. At this time, in order to enhance the strength of the bottom wall 1121 and prevent the bottom wall 1121 from being deformed, it is conceivable to provide a plurality of protrusions 11211 protruding toward the inside of the receiving cavity on the inner side surface of the bottom wall 1121, where the protrusions 11211 may be formed by punching a sheet metal part constituting the bottom wall 1121 toward the inside of the receiving cavity, or the protrusions 11211 may be solid blocks provided on the bottom wall 1121. At least a portion of mounting plate retainer 150 may be disposed on nubs 11211 to enhance the ability of mounting plate retainer 150 to deform when electrical cassette 100 is impacted.

Referring to fig. 2, as mentioned above, the electronic control box 100 may include the refrigerant heat dissipation unit 140 disposed on the mounting plate 130, for example, the refrigerant heat dissipation unit 140 may be disposed at a bottom side of the mounting plate 130, the circuit board may be disposed at a top side of the mounting plate 130, and when the mounting plate 130 is mounted on the bottom wall 1121 by the mounting plate fixing member 150, the refrigerant heat dissipation unit 140 may be located between the bottom wall 1121 and the mounting plate 130.

Here, the refrigerant heat dissipation unit 140 may include a plurality of heat dissipation pipes 141 arranged at intervals, for example, a refrigerant may be accommodated in the heat dissipation pipes 141, and the refrigerant heat dissipation unit 140 may realize heat dissipation by means of circulation flow of the refrigerant in the heat dissipation pipes 141.

Here, in order to avoid interference with the refrigerant heat dissipating unit 140, the mounting plate fixtures 150 may be located at intervals between the heat dissipating pipes 141, that is, the mounting plate fixtures 150 may penetrate through the intervals existing in the refrigerant heat dissipating unit 140 and then be connected to the mounting plate 130. Thus, the refrigerant heat dissipation unit 140 is actually located in the space defined by the bottom wall 1121, the mounting plate fixing member 150 and the mounting plate 130, and at this time, the arrangement of the refrigerant heat dissipation unit 140 does not result in an increase in the thickness of the electrical control box.

With reference to fig. 2, in order to circulate the refrigerant in the refrigerant heat dissipation unit 140, the refrigerant heat dissipation unit 140 further includes a liquid inlet pipe 142 and a liquid outlet pipe 143, the liquid inlet pipe 142 and the liquid outlet pipe 143 may be located at two sides of the heat dissipation pipe 141, and both the liquid inlet pipe 142 and the liquid outlet pipe 143 are communicated with the heat dissipation pipe 141.

Referring to fig. 4, it should be noted that, since the diameters of the liquid inlet pipe 142 and the liquid outlet pipe 143 are slightly larger than the heat dissipating pipe 141, an avoiding groove 11212 recessed toward the outside of the accommodating cavity may be respectively disposed on the bottom wall 1121 at a position opposite to the liquid inlet pipe 142 and the liquid outlet pipe 143. For example, the avoidance groove 11212 may be located at the edge position of the opposite sides of the bottom wall 1121, and the length direction of the avoidance groove 11212 may be along the width direction (X-axis direction) of the electrical control box 100, that is, the avoidance groove 11212 may extend along the width direction of the electrical control box 100.

It can be understood that the box body 110 is provided with an opening 1125 at a position corresponding to the inlet pipe 142 and the outlet pipe 143, so that the inlet pipe 142 and the outlet pipe 143 can extend out of the box body 110. Illustratively, referring to fig. 1, the sidewall 1122 may be provided with an opening 1125 through which the inlet pipe 142 and the outlet pipe 143 pass.

In addition, in the embodiment of the present invention, the circuit board may have a plurality of cables thereon to achieve electrical connection between different functional modules on the circuit board, wherein at least a portion of the cables may be disposed around an edge of the circuit board, and it is considered that a component for collecting the cables is disposed on the side wall 1122 of the box body 110 to store the cables on the circuit board.

The first sidewall 1123 may be, for example, the sidewall 1122 located in the negative direction of the Y-axis in fig. 4, the first sidewall 1123 may be provided with a strip-shaped cable holder 160, and the cable holder 160 extends along the length direction (X-axis direction) of the first sidewall 1123, and in fact, in the case where the cable holder 160 is provided on the first sidewall 1123, the cable holder 160 may extend to the entire length direction of the first sidewall 1123. Cable retainer 160 may include clips that can collapse the cables and that are spaced apart on a surface of cable retainer 160 facing away from first sidewall 1123. Thus, the cable may be secured to the first sidewall 1123 by a crimp on the surface of the cable retainer 160 as it passes adjacent the first sidewall 1123.

In the above-described aspect, the cable holder 160 includes the connection portion 161 and the fixing portion 162 connected to the edge of the connection portion 161, the surface of the connection portion 161 may be used to provide a clip, and the fixing portion 162 may be bent toward the first sidewall 1123 and supported on the first sidewall 1123, so that a gap may be provided between the connection portion 161 and the first sidewall 1123. Here, the cable fixing member 160 may be integrally made of an insulating material, so that the cable may be supported in an insulating manner.

In an embodiment of the present invention, referring to fig. 4, 5, and 6, the first sidewall 1123 may include a sidewall body 11231 and a clamping edge 11232 connected to the periphery of the sidewall body 11231, and the clamping edge 11232 may extend around the entire circumference of the first sidewall 1123 and protrude toward the inside of the receiving cavity. Thus, when the first and

second side walls

1123 and 1124 are connected to the bottom wall 1121, the top end surface of the second side wall 1124 and the clamping edge 11232 together define a clamping space 170 capable of clamping with the cover 111, and such clamping spaces 170 are formed at the four corner portions of the clamping edge 11232, so that the cover 111 can be firmly clamped on the lower case 112.

In order to fix the cover 111 to the lower case 112, the cover 111 may be fixed to the case 112 by a fastening member, for example, referring to fig. 7, a mounting hole 1111 is formed in the cover 111, and the cover 111 may be fixed to the lower case 112 by a fastening member passing through the mounting hole 1111 and being fixed to the side wall 1122.
