Description

Technical Field

[0001] The utility model relates to the technical field of electronic controllers, and more specifically, to a wire harness protection shell for an electronic controller. Background Art

[0002] An electronic controller is a miniaturized computer management center. It takes signal (data) acquisition, calculation processing, analysis and judgment, and decision-making as inputs, and then issues control instructions and commands actuators to work as outputs. In some cases, it also needs to provide a stable power supply or reference voltage to sensors. Its core is a microcomputer system with a single-chip microcomputer as the main body, integrating multiple technologies such as automatic control, microelectronics, power electronics, sensing, and communication.

[0003] The patent with the publication number CN216905652U discloses an electronic controller, which relates to the field of electronic controller devices. Aiming at the problems of insufficient fixation of the circuit board in the existing electronic controller and low sealing performance of the electronic controller, the following scheme is proposed. It includes an electronic controller bottom shell and an electronic controller upper cover. Lower circular pieces are welded at the four corners of the bottom inner wall of the electronic controller bottom shell. This utility model realizes the effect of quickly installing and fixing the circuit board by using the combination of the tip tension of the expansion bolt and the inner wall of the hollow tube, and maintains the stability and shock absorption of the circuit board through the elastic potential energy of the spring. At the same time, the rubber sealing strip at the bottom edge of the upper cover fits with the groove at the top edge of the bottom shell. Through the tight cooperation between the groove and the rubber sealing strip, a sealed environment is formed between the bottom shell and the upper cover to prevent external dust and water from entering the interior of the electronic controller and damaging the circuit board.

[0004] Although this device has many beneficial effects, there are still the following problems: Although this electronic controller can prevent external dust and water from entering the interior of the electronic controller and damaging the circuit board, during use, the wire harness in the electronic controller is often exposed, vulnerable to mechanical collision, water vapor erosion, and electromagnetic interference, thereby affecting the normal operation of the device.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0030] An electronic controller wire harness protection shell includes a controller body 1. A plurality of wire harness bodies 2 are electrically connected inside the controller body 1. The plurality of wire harness bodies 2 extend to the outside of the controller body 1. A protection shell body 3 is provided on the outer surface of the controller body 1. The plurality of wire harness bodies 2 are located inside the protection shell body 3. It further includes:

[0031] An installation component, which is located between the controller body 1 and the protection shell body 3, is used to install the protection shell body 3 on the outer surface of the controller body 1 and is convenient for disassembly;

[0032] A plurality of wire harness fixing components, which are located on the top inner wall of the protection shell body 3 and are evenly distributed, are used to fix the plurality of wire harness bodies 2 inside it. The protection shell body 3 is used to protect the plurality of wire harness bodies 2 exposed outside.

[0033] Furthermore, the installation component includes an installation seat 6, an installation block 7 and a connecting column 11. Two installation seats 6 are fixedly connected to the top of the protection shell body 3. Connecting columns 11 are movably connected inside both of the two installation seats 6. Two installation blocks 7 are fixedly connected to the outer surface of the controller body 1. The two connecting columns 11 are inserted into the corresponding installation blocks 7. Move the clamping column 10 so that it moves from the horizontal direction of the notch 8 to the vertical direction. As the clamping column 10 moves, the connecting column 11 is driven to disengage from the installation block 7.

[0034] Furthermore, first springs 9 are elastically connected inside both of the two installation seats 6. The two first springs 9 are both located inside the corresponding connecting columns 11. When the first springs 9 are not squeezed, they will reset, thereby driving the connecting columns 11 to be completely inserted into the installation blocks 7.

[0035] Furthermore, clamping columns 10 are fixedly connected to the outer surfaces of the two connecting columns 11. Notches 8 are opened on the outer surfaces of the two installation seats 6. The two notches 8 are both arranged in an L-shaped structure. The two clamping columns 10 are slidably clamped with the corresponding notches 8, and the clamping columns 10 are moved in the notches 8.

[0036] Furthermore, a plurality of equally spaced heat dissipation holes 4 are provided on both outer surfaces of the protective shell body 3, and a plurality of equally spaced heat dissipation fins 5 are fixedly connected to the outer surface of the protective shell body 3. The heat dissipation holes 4 allow air to circulate and take away the heat generated inside the controller body 1. The heat dissipation fins 5 increase the heat dissipation area, conduct the heat from the controller body 1 to the fins, and dissipate the heat to the surrounding environment through convection and radiation, further improving the heat dissipation efficiency.

[0037] Furthermore, the wire harness fixing assembly includes a connecting plate 12, a second spring 13, and a clamping block 14. The connecting plate 12 is fixedly connected to the top inner wall of the protective shell body 3. The clamping block 14 is fixedly connected to the outer surface of the connecting plate 12. The clamping block 14 is arranged in a Ω-shaped structure. Two symmetrically distributed second springs 13 are elastically connected to the outer surface of the connecting plate 12. The two second springs 13 are fixedly connected to the clamping block 14. Pushing the wire harness body 2 into the clamping block 14 will squeeze the second spring 13 during the pushing process, and the clamping block 14 will squeeze inward and tightly hold the wire harness body 2, thus achieving fixation.

[0038] Furthermore, the clamping block 14 is made of rubber. The clamping block 14 is clamped with the corresponding wire harness body 2. The rubber clamping block 14 not only provides good insulation performance, but also ensures the firmness of the wire harness fixation and the buffering effect on vibration and impact through its elastic characteristics.

[0039] Working principle: When the staff needs to use the wire harness protective case of the electronic controller, when the protective case body 3 needs to be installed on the controller body 1, the clamping post 10 starts in the vertical direction of the notch 8. At this time, the first spring 9 is in a compressed state, and the connecting post 11 is located inside the mounting seat 6. Then align the two mounting seats 6 with the mounting block 7, and move the clamping post 10 in the notch 8 so that it moves from the vertical direction to the horizontal direction. At this time, the first spring 9 is not squeezed and will reset, thereby driving the connecting post 11 to be completely inserted into the mounting block 7. This design enables the protective case body 3 to be firmly fixed on the controller body 1 while maintaining the convenience of disassembly. If it is necessary to disassemble the protective case body 3, just move the clamping post 10 so that it moves from the horizontal direction of the notch 8 to the vertical direction. As the clamping post 10 moves, it will drive the connecting post 11 to disengage from the mounting block 7. The clamping block 14 is designed in a Ω-shaped structure and has a certain elasticity, which can be tightly clamped with the wire harness body 2. When the wire harness body 2 is placed at the opening of the clamping block 14, push the wire harness body 2 into the clamping block 14. During the pushing process, the second spring 13 will be squeezed, and the clamping block 14 will squeeze inward and tightly hold the wire harness body 2, thus achieving fixation. The rubber material clamping block 14 not only provides good insulation performance, but also ensures the firmness of wire harness fixation and the buffering effect on vibration and impact through its elastic characteristics. In order to ensure the stability of the controller body 1 and the internal electrical components during long-term operation, a plurality of equally spaced heat dissipation holes 4 are provided on the outer surfaces of both sides of the protective case body 3. These heat dissipation holes 4 allow air to circulate and take away the heat generated inside the controller body 1. A plurality of equally spaced heat dissipation fins 5 are also fixedly connected to the outer surface of the protective case body 3. The heat dissipation fins 5 increase the heat dissipation area, conduct the heat from the controller body 1 to the fins, and dissipate the heat to the surrounding environment through convection and radiation, further improving the heat dissipation efficiency.
