Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a modular low-power vehicle controller. Background Technology

[0002] The vehicle control system, also known as the powertrain controller, is the core control component of the entire vehicle. It collects signals from the accelerator pedal, brake pedal, and other components, makes corresponding judgments, and controls the actions of the lower-level component controllers. The vehicle controller collects driver signals and vehicle status, and manages, schedules, analyzes, and calculates network information through the CAN bus. It performs corresponding energy management based on different vehicle configurations, realizing functions such as vehicle drive control, energy optimization control, brake feedback control, and network management.

[0003] For example, the existing Chinese patent with publication number CN210734045U discloses a vehicle controller. The first screw hole of the injection-molded upper shell is locked to the corresponding second screw hole on the injection-molded lower shell by a self-tapping screw. The threaded connection method is simple, stable and easy to disassemble.

[0004] Since the controller is installed on the vehicle, and the vehicle will often vibrate due to various factors such as the road surface during driving, the self-tapping screws are very likely to loosen from the screw holes over time, thus losing the stability of the connection.

[0005] Therefore, a modular, low-power vehicle controller is needed. Utility Model Content

[0006] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies. This invention proposes a modular, low-power vehicle controller to address the issue of self-tapping screws being easily affected by vibration, leading to loosening between the screw and the screw hole, and consequently, loss of connection stability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a modular low-power vehicle controller, including an upper shell, and a lower shell is connected to the lower part of the upper shell by bolts;

[0008] Two sets of connecting ears 1 are fixedly installed on both sides of the upper shell, and two sets of connecting ears 2 are fixedly installed on both sides of the lower shell. A locking block 1 is fixedly installed on the upper end of the connecting ear 2. A locking groove is opened on the end face of the locking block 1. Two sets of semi-rings are symmetrically fixedly installed on the outer wall of the bolt. A locking block 2 is fixedly installed below one set of semi-rings. A sliding groove is opened inside the locking block 2. An elastic element is installed on the surface of the sliding groove.

[0009] The elastic element includes a spring fixedly connected to the surface of the slide groove. A plug is fixedly installed at the lower end of the spring, and a lever is fixedly installed on one side of the plug. Both the plug and the lever slide in contact with the surface of the slide groove. During installation, firstly, multiple sets of connecting ears one and multiple sets of connecting ears two are aligned one-to-one. Then, the bolt is inserted into the inner side of the connecting ear one, and two sets of semi-rings are fitted onto the outer wall of the bolt. Subsequently, the two sets of semi-rings are welded together. Then, the bolt is screwed to connect with the connecting ear two via threads. During the threaded connection process, the lever is moved to drive the plug to compress the spring, causing the plug to retract into the slide groove. When the upper shell contacts the lower shell, the slide groove and the retaining groove correspond. Then, the lever is released, the spring returns to its original position, and pushes the plug into the retaining groove and abuts against it. This prevents the bolt from rotating during subsequent use, thus preventing loosening between the plug and the connecting ear two and ensuring the stability of the threaded connection.

[0010] Preferably, the outer wall surface of the bolt has circumferentially shaped positioning holes, and multiple positioning pins are fixedly installed on the inner side of the semi-ring. The positioning pins match the positioning holes. During the installation process, the matching of the positioning holes and positioning pins facilitates the quick positioning and installation of the semi-ring by personnel, thereby improving the overall installation efficiency.

[0011] Preferably, a sealing groove is provided on the lower end face of the upper shell, and a sealing strip is fixedly installed on the upper end face of the lower shell. The sealing strip matches the sealing groove. After installation, the sealing strip will penetrate into the interior of the sealing groove, which can effectively block the entry of dust in the air and avoid affecting the internal components.

[0012] Preferably, rubber protective plates are fixedly installed at the four corners of the outer walls of the upper and lower shells. The rubber protective plates can effectively buffer external impacts and reduce damage to internal components.

[0013] Preferably, multiple heat dissipation strips are fixedly installed on the upper end face of the upper shell. Multiple heat dissipation strips can greatly increase the contact area with air and enhance the heat dissipation effect.

[0014] Preferably, a control module is fixedly installed on the inner side of the upper and lower shells. Installing the control module between the upper and lower shells can provide good protection for it and facilitate connection with the circuit.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model proposes a modular low-power vehicle controller. During installation, multiple sets of connecting lug 1 and multiple sets of connecting lug 2 are first matched one-to-one. Then, bolts are inserted into the inner side of connecting lug 1, and two sets of semi-rings are fitted onto the outer wall of the bolt. Subsequently, the two sets of semi-rings are welded together. Then, the bolt is tightened to connect with connecting lug 2 via threads. During the threaded connection process, by moving the toggle block, the insert block is driven to compress the spring, causing the insert block to retract into the slide groove. When the upper shell contacts the lower shell, the slide groove and the slot correspond. Then, the toggle block is released, the spring returns to its original position, and pushes the insert block into the slot and abuts against it. This ensures that the bolt will not rotate during subsequent use, thus preventing loosening between the bolt and connecting lug 2 and guaranteeing the stability of the threaded connection.
