Description
Technical Field
[0001] This utility model belongs to the field of automotive technology and relates to a novel ECU assembly. Background Technology
[0002] The ECU (Electronic Control Unit), also known as the "vehicle computer" or "on-board computer," is a specialized microcomputer controller for automobiles. Like a regular computer, it consists of a microprocessor (CPU), memory (ROM, RAM), input / output interfaces (I / O), analog-to-digital converters (A / D), and large-scale integrated circuits for shaping and driving functions.
[0003] Existing ECU assemblies generally consist of a housing, a circuit board, a pin assembly, and a pin housing for mounting the pin assembly. The circuit board is horizontally mounted inside the housing and secured to it with multiple bolts. Removing or installing the circuit board requires first opening the housing and then unscrewing the bolts, making the process rather cumbersome. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing an ECU assembly that is easy to assemble.
[0005] The objective of this utility model can be achieved through the following technical solution: A novel ECU assembly includes a housing, a circuit board horizontally disposed within the housing, and a pin housing disposed outside the housing for mounting pin headers. The housing is characterized by a cover plate for sealing, located on the circuit board. Fixing portions for connection are fixedly disposed on both sides of the housing. A positioning component for positioning the cover plate is disposed on the fixing portion. The positioning component consists of a positioning element and a return spring. The fixing portion has an L-shaped structure, and there is a space between the fixing portion and the cover plate for the cover plate to move. An installation groove for mounting the positioning component is provided within the fixing portion. A snap-fit groove is provided on the cover plate for the positioning element to partially engage. One end of the positioning element extends out of the installation groove and into the snap-fit groove of the cover plate. The other end of the positioning element extends out of the fixing portion and is connected to a pull rod. The return spring allows the positioning element to move up and down within the installation groove.
[0006] In the aforementioned novel ECU assembly, the positioning member is provided with a sliding part that slides within a mounting groove, one end of the reset spring is connected to the sliding part, and the other end of the reset spring is connected to the mounting groove of the fixing part.
[0007] In the aforementioned novel ECU assembly, there are two fixing parts, which are respectively disposed on the left and right sides of the housing. Each fixing part is provided with two positioning components for positioning the cover plate.
[0008] In the aforementioned novel ECU assembly, the housing is provided with a positioning part for positioning the cover plate. The positioning part is integrally formed with the housing, and the height of the positioning part is slightly higher than the height of the cover plate when it is installed.
[0009] Compared with existing technologies, this ECU assembly uses a positioning component to detachably fix the cover plate to the housing, making it easy for operators to remove the cover plate from the housing and repair and replace internal components such as the circuit board. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] Figure 2 This is a cross-sectional structural diagram of the present invention.
[0012] In the diagram, 1 is the housing; 2 is the circuit board; 3 is the cover plate; 4 is the fixing part; 5 is the positioning assembly; 6 is the positioning component; 7 is the return spring; 8 is the mounting groove; 9 is the pull rod; 10 is the sliding part; and 11 is the positioning part. Detailed Implementation
[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2 As shown, this novel ECU assembly includes a housing 1, a circuit board 2 horizontally disposed within the housing 1, and a pin housing disposed outside the housing 1 for mounting pin headers. A cover plate 3 for sealing is disposed on the housing 1 and located on the circuit board 2. Fixing parts 4 for connection are fixedly disposed on both sides of the housing 1. A positioning component 5 for positioning the cover plate 3 is disposed on the fixing part 4. The positioning component 5 consists of a positioning element 6 and a return spring 7. The fixing part 4 is L-shaped, and there is a space between the fixing part 4 and the cover plate 3 for the cover plate 3 to move. An installation groove 8 for mounting the positioning component 5 is provided in the fixing part 4. A snap-fit groove for partially engaging the positioning element 6 is provided on the cover plate 3. One end of the positioning element 6 extends out of the installation groove 8 and into the snap-fit groove of the cover plate 3. The other end of the positioning element 6 extends out of the fixing part 4 and is connected to a pull rod 9. The positioning element 6 can move up and down within the installation groove 8 by the action of the return spring 7.
[0015] To elaborate further, when the cover plate 3 needs to be installed, first pull the lever 9 to retract the positioning member 6 into the mounting groove 8, compressing the return spring 7, and then install the cover plate 3 laterally onto the housing 1, with the outer side of the cover plate 3 in contact with the positioning part 11 of the housing 1. Release the lever 9, and the return spring 7 will spring back, with one end of the positioning member 6 extending out of the mounting groove 8 and partially extending into the snap-fit groove of the cover plate 3, thereby fixing the cover plate 3. When the cover plate 3 needs to be disassembled, pull the lever 9 to release the positioning of the cover plate 3, retracting the positioning member 6 into the mounting groove 8, moving the cover plate 3 upward a certain distance, and then moving it laterally out, thereby removing the cover plate 3 from the housing 1.
[0016] To elaborate further, the positioning component 6 is provided with a sliding part 10 that slides within the mounting groove 8. One end of the return spring 7 is connected to the sliding part 10, and the other end of the return spring 7 is connected to the mounting groove 8 of the fixing part 4.
[0017] To elaborate further, there are two fixing parts 4, which are respectively located on the left and right sides of the housing 1. Each fixing part 4 is provided with two positioning components 5 for positioning the cover plate 3.
[0018] To elaborate further, the housing 1 is provided with a positioning part 11 for positioning the cover plate 3. The positioning part 11 is integrally formed with the housing 1, and the height of the positioning part 11 is slightly higher than the height of the cover plate 3 when it is installed.
[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0020] Although this document frequently uses terms such as housing 1, circuit board 2, cover plate 3, fixing part 4, positioning assembly 5, positioning element 6, return spring 7, mounting groove 8, pull rod 9, sliding part 10, and positioning part 11, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
