As shown in fig. 1 to 4, an automotive electronic control module 1 according to an embodiment of the present invention includes a control board 10 and a mounting ear ring 20.

The control board 10 has a plurality of electronic components 11 thereon. The mounting lugs 20 are disposed on two opposite sides of the control board 10, for example, the control board 10 may be a rectangular PCB, the mounting lugs 20 are pre-connected with the control board 10 and then integrally injection-molded, and the mounting lugs 20 have through holes 21 therein. It should be understood that the term "pre-attached" refers to the attachment and/or positioning of the mounting ear 20 to the control panel 10 before the attachment ear 20 is injection molded with the control panel 10, and the injection molding of the mounting ear 20 over the control panel 10 after the pre-attachment.

According to the utility model discloses an automobile electronic control module 1, installation earring 20 is at first in advance connected with control panel 10 on two relative edges of control panel 10, through establishing installation earring 20 in advance connected in the relative both sides of control panel 10, makes installation earring 20 and control panel 10 have had certain assembly relation before moulding plastics, makes installation earring 20 and control panel 10 form overall structure through moulding plastics again, moulds plastics and further reinforces installation earring 20 and control panel 10.

Therefore, the sealing groove does not need to be formed and the sealant does not need to be coated, the structure and the process are simple, the cost is low, and the effects of insulation, vibration reduction, moisture prevention, dust prevention and the like are achieved. Furthermore, the installation earring 20 and the control board 10 are pre-connected, on the basis that the injection molding material 30 reinforces the installation earring 20 and the control board 10, the direct connection between the installation earring 20 and the control board 10 is reinforced, the installation earring 20 is formed at a position close to the side of the control board 10, and the injection molding material 30 between the installation earring 20 and the control board 10 is not easy to break, so that the structural strength between the installation earring 20 and the control board 10 is enhanced, and the risk that the installation earring 20 falls off is greatly reduced. Furthermore, the pre-connection between the mounting ear ring 20 and the control board 10 prevents the mounting ear ring 20 from separating from the control board 10 due to the fracture of the injection molding material 30.

Therefore, according to the utility model discloses an automobile electronic control module 1 has structure and simple process, and the cost is lower, and the assembly is stable, advantages such as structural strength height.

After the installation earring 20 and the control board 10 are pre-connected, the injection molding material 30 can be injected into a mold by low-temperature injection molding, for example, by using a low injection pressure (1.5 to 40bar) and is rapidly cured and molded (5 to 50 seconds), so as to achieve the effects of insulation, temperature resistance, impact resistance, vibration reduction, moisture resistance, water resistance, dust resistance, chemical corrosion resistance, and the like.

In some embodiments of the present invention, as shown in fig. 1 and 3, the opposite sides of the control panel 10 are respectively provided with a first engaging structure 12, the mounting ear ring 20 is provided with a second engaging structure 22, and the first engaging structure 12 and the second engaging structure 22 are engaged to pre-position the mounting ear ring 20 on the control panel 10.

Because control panel 10 has first cooperation structure 12, second cooperation structure 22 corresponds the setting with first cooperation structure 12, and control panel 10 has the assembly structure with installation earring 20, and through the relative both sides of first cooperation structure 12 and second cooperation structure 22 cooperation at control panel 10, control panel 10 can be connected the assembly with installation earring 20 in relative both sides, and control panel 10's atress is more balanced, and then control panel 10 and installation earring 20's assembly is more stable.

In some embodiments of the present invention, as shown in fig. 1 and 3, the first engaging structure 12 is a mounting groove 120 formed on the corresponding side of the control board 10, the mounting ear ring 20 is embedded in the mounting groove 120 through the second engaging structure 22, and the central axis of the through hole 21 of the mounting ear ring 20 is perpendicular to the board body of the control board 10.

By constructing the mounting groove 120 in the control board 10, the control board 10 has an assembly structure for assembling the mounting ear ring 20, the mounting ear ring 20 is embedded in the mounting groove 120, the mounting ear ring 20 is connected with the control board 10, the injection molding material 30 is reduced, the manufacturing cost is reduced, and the structure of the automotive electronic control module 1 is more compact. In addition, the central axis of the through hole 21 is perpendicular to the plate body of the control plate 10, so that the installation and positioning of the control plate 10 are facilitated.

Further, as shown in fig. 1 and 3, the second fitting structure 22 is a fitting groove 220 formed on the mounting ear 20 along at least a portion of the circumference thereof, the shape of the fitting groove 220 is adapted to the shape of the mounting groove 120, and after a portion of the mounting ear 20 first extends into the mounting groove 120, the edge of the control board 10 at the mounting groove 120 is fitted into the fitting groove 220.

For example, as shown in fig. 4 and 5, the wall thickness of the mounting ear ring 20 is d, about 1.0mm to 2.0mm, the insertion groove 220 is formed at a middle position of the outer wall of the mounting ear ring 20, and the depth of the groove is w, about 0.4mm to 1.0mm, the width of the groove is s, about 1.5mm to 1.7mm, so that the insertion groove 220 has sufficient structural strength while ensuring stable assembly with the mounting groove 120 and the control board 10.

Further, as shown in fig. 3 and 4, the mounting groove 120 is a non-circular groove, such as a half-waist groove, and the outer contour of the mounting ear ring 20 is configured in an oblong shape. The mounting groove 120 is adapted to the shape of the mounting ear 20, and the mounting ear 20 extends into the mounting groove 120 and is inserted into the mounting groove 120, so as to keep the assembly of the mounting ear 20 and the control panel 10 stable. Because the outer contour of the mounting ear ring 20 is oblong, after the mounting ear ring 20 is embedded into the semi-waist-shaped mounting groove 120 through the embedding groove 220, the mounting ear ring 20 and the control panel 10 cannot rotate, and the risk that the mounting ear ring 20 falls off from the control panel 10 is reduced.
