Description

Technical Field

[0001] This utility model belongs to the field of controller technology, and more specifically, it relates to a controller with port protection function. Background Technology

[0002] The electric vehicle controller is like the "brain commander" of the electric vehicle. It can precisely control the motor speed and torque according to the throttle signal, protect the battery, and prevent overcharging, over-discharging and high current discharge.

[0003] When repairing electric vehicles, it is necessary to troubleshoot the cause of the malfunction. This troubleshooting requires checking the connection ports of the controller and power cord, specifically the ends of the power cord and the connections of the terminals. Checking the ports requires opening the protective covers. However, existing protective covers are usually attached to the controller housing using clips and slots. Opening these covers typically requires operators to pry them open with a screwdriver, which is cumbersome and prone to damage after repeated prying, limiting their practical application. Therefore, this paper researches and improves upon the existing structure and its shortcomings, providing a controller with port protection functionality to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a controller with port protection function, which is achieved by the following specific technical means:

[0005] A controller with port protection function includes a main housing. A connection groove is provided on the top side of the main housing. Multiple sets of terminals for connecting power cords are fixedly installed in the connection groove. A connecting cylinder is installed inside the connection groove. Two sets of fixing seats are symmetrically fixedly installed inside the connecting cylinder. A sliding rod is slidably connected to the inner side of each of the two sets of fixing seats. Limit seats are fixedly installed at both ends of the connecting cylinder. Connecting rods are slidably connected to the inner side of each limit seat. Two sets of connecting holes are provided in the connection groove corresponding to the two sets of connecting rods, and the connecting holes are slidably connected to the connecting rods. Two sets of limiting rings are symmetrically fixedly installed on the outer side of the connecting cylinder. A protective cover is rotatably connected to the outer side of each limiting ring.

[0006] Furthermore, a lever is fixedly installed on the outer side of the slide rod, and both the protective cover and the connecting cylinder are provided with sliding grooves that are slidably connected to the lever.

[0007] Furthermore, the protective cover is provided with two sets of receiving grooves corresponding to the two sets of levers, which can be used to accommodate the levers.

[0008] Furthermore, each of the multiple sets of terminals is equipped with a wire feeding rack that is fixedly connected to the connecting slot.

[0009] Furthermore, the protective cover is provided with multiple sets of cable trays corresponding to multiple sets of cable trays.

[0010] Furthermore, a partition plate that is fixedly connected to the connection slot is installed between each group of adjacent terminals.

[0011] Furthermore, the main housing is integrally formed with multiple sets of heat dissipation fins, and the bottom two ends of the main housing are integrally formed with fixing plates. Each fixing plate is symmetrically provided with two sets of waist-shaped grooves that can be used to connect with the electric vehicle.

[0012] Furthermore, one end of the connecting rod is located inside the connecting cylinder and is fixedly installed with a limiting plate that is slidably connected to the inner wall of the connecting cylinder. One side of the limiting plate is fixedly connected to one end of the sliding rod. A spring is sleeved on the outside of the sliding rod, and the two ends of the spring abut against the fixed seat and one side of the limiting plate, respectively. A torsion spring sleeved on the outside of the connecting cylinder is installed between the two sets of limiting rings and the adjacent limiting seats. One end of the torsion spring is fixedly connected to one side of the limiting ring, and the other end of the torsion spring is fixedly connected to the inside of the protective cover.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model enables the protective cover to rotate flexibly through the cooperation of the connecting cylinder and the limiting ring. Through the cooperation of the torsion spring and the protective cover, force can be applied to the protective cover so that it can always be kept closed when it does not need to be opened. When it is necessary to inspect the port, the protective cover can be opened flexibly, which increases the convenience of the product during use.

[0015] 2. This utility model, through the cooperation of the lever and the slide bar, can realize the flexible movement of the connecting rod and the limiting plate. When a fault is found at the port, the connecting rod can be moved flexibly out of the connecting hole, and the protective cover, connecting cylinder and connecting rod can be taken out from the connecting groove. This avoids the protective cover obstructing the operator when the operator is repairing the power cord and terminal block, and increases the practicality of the product. Attached Figure Description

[0028] This utility model provides a controller with port protection function, including a main housing 1. The top side of the main housing 1 is provided with a connecting groove 2. Multiple sets of terminals 3 for connecting power cords are fixedly installed in the connecting groove 2. A connecting cylinder 4 is installed inside the connecting groove 2. Two sets of fixing seats 5 are symmetrically fixedly installed inside the connecting cylinder 4. Sliding rods 6 are slidably connected to the inner sides of both sets of fixing seats 5. Limiting seats 7 are fixedly installed at both ends of the connecting cylinder 4. Connecting rods 8 are slidably connected to the inner sides of the limiting seats 7. Two sets of connecting holes are provided in the connecting groove 2 corresponding to the two sets of connecting rods 8. The connecting holes are slidably connected to the connecting rods 8. Two sets of limiting rings 11 are symmetrically fixedly installed on the outer side of the connecting cylinder 4. A protective cover 13 is rotatably connected to the outer side of the limiting rings 11.

[0029] The slide bar 6 is fixedly mounted with a lever 14 on its outer side. The protective cover 13 and the connecting cylinder 4 are both provided with a sliding groove 15 that is slidably connected to the lever 14, which can realize the flexible movement of the connecting rod 8 and the convenient removal of the protective cover 13 from the connecting groove 2.

[0030] The protective cover 13 is provided with two sets of receiving grooves 16 corresponding to the two sets of levers 14, which can be used to accommodate the levers 14 to prevent the levers 14 from hindering the rotation of the protective cover 13.

[0031] Each of the multiple sets of terminals 3 is equipped with a cable tray 17 that is fixedly connected to the connecting slot 2 on one side, which facilitates the fixing of the power cord.

[0032] The protective cover 13 is provided with multiple sets of cable trays 17, which can allow the power cord to pass through the cable trays 18 and exit the protective cover 13, thereby reducing the gap between the protective cover 13 and the connecting groove 2.

This allows the protective cover 13 to be kept closed when it does not need to be opened.

[0036] The working principle of this embodiment is as follows: When it is necessary to inspect the terminal block 3 and the power cord, first rotate the protective cover 13. If no problem is found, after releasing the protective cover 13, the torsion spring 12 will drive the protective cover 13 to reset and keep the protective cover 13 in a closed state. If a problem is found, press the two sets of levers 14 to drive the slide bar 6 to move. The slide bar 6 drives the connecting rod 8 away from the connection hole. Take out the protective cover 13 and repair the terminal block 3 and the power cord. After the repair is completed, press the lever 14 to make the connecting rod 8 be located inside the connecting cylinder 4. Put the protective cover 13 into the connecting groove 2, release the lever 14 and move the protective cover 13 to a suitable position. At this time, the spring 10 drives the connecting rod 8 to move into the connection hole and fixes the protective cover 13 and the connecting cylinder 4, thus completing the inspection of the terminal block 3 and the power cord.
