[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the vehicle ECU includes a shell, in which a circuit board 3 and a control element are arranged, and the shell is composed of an upper shell 1 and a lower shell 2. The lower shell 2 is provided with four mounting protrusions 4 for mounting the circuit board 3. The circuit board 3 is inserted into the mounting protrusions 4 and positioned by the mounting protrusions 4. The upper end of the circuit board 3 is also connected to the upper shell 1, which improves the stability of the circuit board 3. A fixing portion 5 for fixing the upper shell 1 is provided on the outer peripheral side of the upper shell 1. A positioning rod 6 is provided on the upper shell 1 and at a position relative to the mounting protrusion 4. The positioning rod 6 is inserted into the mounting protrusion 4 of the lower shell 2 for positioning. Two positioning components 7 are provided on the positioning rod 6. The two positioning components 7 include a positioning portion 8 and a connecting spring 9. A mounting groove 10 for mounting the positioning portion 8 is opened on the positioning rod 6. A groove 13 is opened at the lower end of the lower shell 2. The positioning rod 6 extends out of the groove 13 and is connected to the bottom wall of the groove 13 through the positioning portion 8, thereby fixing the upper shell 1 to the lower shell 2.
[0016] To be more specific, when installing it, match the upper shell 1 with the lower shell 2, then align the positioning rod 6 of the upper shell 1 with the through hole on the mounting protrusion 4, and then press the positioning portion 8 into the mounting groove 10, so that the positioning rod 6 slides in the mounting protrusion 4 until it extends out of the mounting protrusion 4, and the connecting spring 9 rebounds, so that the positioning portion 8 extends out of the mounting groove 10, and the upper shell 1 is fixed to the lower shell 2.
[0017] To further elaborate, one end of the positioning portion 8 extends out of the mounting groove 10 and is used to connect to the bottom wall of the groove 13, and the other end of the positioning portion 8 extends into the mounting groove 10 and is connected to the connecting spring 9. The connecting spring 9 enables the positioning portion 8 to move outside the mounting groove 10.
[0018] In further detail, there is a snap-in groove 11 between the upper housing 1 and the fixing part 5 for snapping with the lower housing 2, and the fixing parts 5 are two and are respectively arranged on the left and right sides of the upper housing 1. The setting of the snap-in groove 11 strengthens the sealing between the upper housing 1 and the lower housing 2 during installation, and improves the service life of the internal parts of the ECU.
[0019] To be more specific, a mounting seat 12 for mounting the lower shell 2 is disposed at a side end thereof, and two mounting seats 12 are disposed on a single side.
[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0021] Although the terms such as upper housing 1, lower housing 2, circuit board 3, mounting protrusion 4, fixing part 5, positioning rod 6, positioning assembly 7, positioning part 8, connecting spring 9, mounting groove 10, clamping groove 11, mounting seat 12, groove 13, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
