Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically a mounting device for a new energy vehicle electronic control unit. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. The electronic control unit of a new energy vehicle is its core control system. In order to ensure the normal use of the electronic control unit, a device is needed to fix the electronic control unit in place during installation.

[0003] Existing new energy vehicle electronic control unit (ECU) fixing devices only provide single-weight fixation for the ECU during use, which is not ideal and carries the risk of loosening over time. Furthermore, there is no timely feedback when the ECU becomes loose, making it impossible for staff to adjust it promptly.

[0004] Therefore, those skilled in the art have provided a mounting device for the electronic control unit of a new energy vehicle to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a fixing device for a new energy vehicle electronic control unit. By setting a fixing mechanism within the control unit box, the fixing mechanism secures the electronic control unit to the box using a screw, rather than employing the traditional snap-fit ​​fixing method. Using a traditional screw provides better protection. Secondly, by setting a locking block, the fixing screw can only be rotated based on the helical groove column when the locking block moves to contact and fix with the hexagonal plate, enabling the assembly and disassembly of the electronic control unit and providing further protection. Finally, by setting a warning mechanism, an audible warning is immediately issued when the electronic control unit becomes loose within the control unit box, reminding the user of the looseness and thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixing device for an electronic control unit of a new energy vehicle includes a fixing device body, a cover plate rotatably connected to the fixing device body, an electronic control unit disposed inside the fixing device body, and the fixing device body and the electronic control unit connected by a fixing mechanism. The fixing mechanism includes a hexagonal plate rotatably connected to the inner wall of the lower end of the fixing device body, and a spiral groove column fixedly connected to the upper end of the hexagonal plate.

[0008] As a further embodiment of this utility model, the fixing mechanism also includes a square frame sleeved on the surface of the control unit. Two square frames are provided, and the two square frames are connected by a connecting rod. A column groove is opened on the square frame, and the spiral groove column passes through the column groove. A fixing screw is provided on the square frame, and the fixing screw is threadedly connected to the spiral groove column.

[0009] As a further embodiment of this utility model, the fixing mechanism further includes a sliding block slidably connected to the inner wall of the lower end of the fixing device body. A locking block is fixedly connected to one end of the sliding block near the hexagonal plate. A magnet is fixedly connected to the concave surface of the locking block, and the locking block is adapted to the hexagonal plate.

[0010] As a further embodiment of this utility model, the main body of the fixing device and the electrical control are not in contact, and the electrical control and the frame are fixed together by screws.

[0011] As a further embodiment of this utility model, a warning mechanism is provided on the main body of the fixing device. The warning mechanism includes a spring column fixedly connected inside the main body of the fixing device. A movable column is fixedly connected to the upper end of the spring column, and the movable column penetrates the lower inner wall of the main body of the fixing device.

[0012] As a further embodiment of this utility model, the warning mechanism also includes a receiver controller and a buzzer fixedly connected to the inner wall of the main body of the fixing device, and the receiver controller, the buzzer and the electrical control are electrically connected to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By incorporating a fixing mechanism within the control box, which secures the control components to the box via screws, instead of the traditional snap-fit ​​method, this design provides excellent protection. Furthermore, the inclusion of a locking block allows the screws to rotate based on the hexagonal groove, enabling the control components to be installed or removed, further enhancing protection. Finally, an audible warning mechanism immediately alerts staff when the control components become loose within the box, facilitating timely adjustment. Attached Figure Description

[0021] Please see Figures 1-5 In this embodiment of the utility model, a fixing device for a new energy vehicle electronic control unit includes a fixing device body 1, a cover plate 2 rotatably connected to the fixing device body 1, an electronic control unit 3 disposed inside the fixing device body 1, and the fixing device body 1 and the electronic control unit 3 connected by a fixing mechanism. The fixing mechanism includes a hexagonal plate 6 rotatably connected to the inner wall of the lower end of the fixing device body 1, and a spiral groove column 7 fixedly connected to the upper end of the hexagonal plate 6. The fixing device body 1 and the cover plate 2 are also fixed by screws. The electronic control unit 3 does not contact the inner wall of the fixing device body 1, but has a gap, which increases the contact area between the electronic control unit 3 and the air, and achieves a good heat dissipation effect.

[0022] The fixing mechanism also includes a square frame 4 sleeved on the surface of the electrical control 3. There are two square frames 4, which are connected by a connecting rod 5. A column groove 8 is opened on the square frame 4, and a spiral groove column 7 passes through the column groove 8. A fixing screw 9 is provided on the square frame 4, and the fixing screw 9 is threadedly connected to the spiral groove column 7. The outer diameter of the spiral groove column 7 is equal to the inner diameter of the column groove 8, which can form a good fixation for the electrical control 3.

[0023] The fixing mechanism also includes a sliding block 11 slidably connected to the inner wall of the lower end of the fixing device body 1. A locking block 10 is fixedly connected to one end of the sliding block 11 near the hexagonal plate 6. A magnet 16 is fixedly connected to the concave surface of the locking block 10. The locking block 10 is adapted to the hexagonal plate 6, which is made of iron. The magnet 16 is used to fix the locking block 10 on the hexagonal plate 6, thereby fixing the spiral groove column 7, so that the fixing screw 9 can rotate based on the spiral groove column 7 instead of rotating synchronously.

[0024] The main body 1 of the fixing device and the electrical control 3 do not contact each other. The electrical control 3 and the frame 4 are fixed together by screws. The frame 4 provides a good fixing effect for the electrical control 3, forming a good protection and preventing the electrical control 3 from colliding.

[0025] The main body 1 of the fixing device is provided with a warning mechanism, which includes a spring column 13 fixedly connected inside the main body 1 of the fixing device. The upper end of the spring column 13 is fixedly connected to a movable column 12. The movable column 12 penetrates the lower inner wall of the main body 1 of the fixing device. The movable column 12 is used to switch the buzzer 15 on and off, and the switch and closure are realized through the spring column 13.

[0026] The warning mechanism also includes a receiver controller 14 and a buzzer 15 fixedly connected to the inner wall of the main body 1 of the fixed device. The receiver controller 14, the buzzer 15 and the electrical control 3 are electrically connected. The receiver controller 14 receives external signals for controlling the buzzer 15.

[0027] The working principle of this utility model is as follows: When it is necessary to remove or fix the electronic control unit 3 from the body 1 of the fixing device, the sliding block 11 needs to be moved first. When the sliding block 11 moves, it will drive the locking block 10 to move synchronously. Finally, it will be connected to the hexagonal plate 6 through the magnet 16 to fix the hexagonal plate 6. Then, the fixing screw 9 is rotated with a screwdriver. At this time, under the fixation of the locking block 10, the hexagonal plate 6 and the spiral groove 7 will not rotate synchronously with the fixing screw 9, so the fixing screw 9 can be removed from the spiral groove 7, and then the electronic control unit can be removed. When component 3 is removed, the installation is performed in reverse. If the control component 3 becomes loose and loses its limit, the movable column 12 will pop out under the action of the spring column 13, turning on the buzzer 15. The buzzer 15 will sound to warn the staff that the control component 3 needs to be adjusted in time. When the control component 3 needs to be removed normally, a signal is sent to the receiver controller 14 through an external remote control (this remote control is installed in the car), which will cut off the power to the buzzer 15. At this time, the movable column 12 will lose control of the buzzer 15, and the buzzer 15 will not work when the control component 3 is removed.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
