Description

Technical Field

[0001] This invention relates to the field of controller housing technology, and more specifically to a wiring harness fixing structure for an electric vehicle controller. Background Technology

[0002] An electric vehicle controller typically consists of a base plate and a housing. The main board is fixed to the base plate, and the housing covers the main board. Numerous wires need to be connected to the main board via soldering, with terminal blocks at the other ends of the wires. Currently, the wiring holes are located on a side panel of the housing and are usually round holes. Since the terminal blocks are already attached to the wires before soldering, and it's difficult to pass the terminal blocks through the wiring holes, the wires generally need to be passed through the wiring holes in the housing and inserted into the main board before soldering. This results in the housing obstructing the worker's view when inserting wires into the main board, significantly impacting wiring efficiency.

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a wiring harness fixing structure for an electric vehicle controller. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a wiring harness fixing structure for an electric vehicle controller. A wire outlet notch is provided on the side plate, and wires are installed by setting a first sealing component and a second sealing component. The outer casing can be installed onto the bottom plate after soldering is completed.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides an electric vehicle controller wiring harness fixing structure, comprising: The outer casing is a rectangular shell with one open side, including a top plate and four side plates, one of which has a cable outlet notch that extends from the inside of the side plate to the edge of the side plate away from the top plate; The base plate has grooves that match the shape of the edges of the four side plates of the outer shell, and a first sealing gasket is provided in the grooves; The outer casing is provided with a fixing device that mates with the wire outlet notch. The fixing device includes a first sealing member and a second sealing member. The first sealing member and the second sealing member can be connected to block the wire outlet notch. Both the first sealing member and the second sealing member are provided with clearance openings for wires to pass through. The two clearance openings are connected to form a circular wire hole. A wire harness clamping device is provided in the wire hole.

[0006] Preferably, the first sealing element includes a first semi-ring and a sealing plate fixed on the first semi-ring, wherein the edge of the sealing plate is fixed with a first flange.

[0007] Preferably, the second sealing element includes a second semi-ring body, one end of which is fixed with a second flange, and the first semi-ring body and the second semi-ring body cooperate to form a threading tube.

[0008] Preferably, a groove is provided on the mating surface of the first half-ring, and a locking block is fixed on the mating surface of the second half-ring. A second sealing gasket is provided in the groove. When the second half-ring is fixed to the first half-ring, the locking block presses the second sealing gasket against the groove.

[0009] Preferably, a third sealing gasket is fitted around the edge of the second semi-annular body and the sealing plate, and the first flange and the second flange cooperate to limit the position of the third sealing gasket.

[0010] Preferably, the first sealing member and the second sealing member are connected by bolts, the side plate has a through hole, the first sealing member is fixedly connected to the side plate by a bolt passing through the through hole, and a sealing ring is provided between the bolt and the side plate.

[0011] Preferably, the wire harness clamping device includes: A retaining ring, the retaining ring comprising two protrusions respectively fixed on the inner walls of the first half-ring and the second half-ring; A clamping sleeve, comprising two mating half-sleeves, wherein the clamping sleeve is threadedly engaged with a threaded spool; An elastic band, which is wound around the wire harness and positioned between the retaining ring and the abutment sleeve; When the clamping sleeve moves toward the retaining ring, the clamping sleeve presses the elastic band tightly, causing the elastic band to hold the wire harness in place.

[0012] Preferably, the two halves are provided with teeth that can be mated.

[0013] Preferably, there are two outlet gaps and two fixing devices, with two adjacent first sealing members fixedly connected and two adjacent second sealing members fixedly connected.

[0014] The beneficial effects of this invention are as follows: A wire outlet notch is provided on one side plate of the outer casing, allowing the middle section of the wire to be inserted into the notch. Then, a first and second sealing member are used to seal the notch, thus securing the wire. This eliminates the need for either end of the wire to pass through the through-hole, making it easier for workers to insert wires onto the motherboard. Furthermore, this invention includes a wire harness clamping device, a second sealing gasket, and a third sealing gasket, which can seal the through-hole, thereby providing the electric vehicle controller with a certain degree of dust and water resistance.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: like Figures 1 to 9 As shown, Embodiment 1 of the present invention provides a wiring harness fixing structure for an electric vehicle controller, including a housing 1, a base plate 5, and a fixing device. The housing 1 is a rectangular shell with one open side. The housing 1 includes a top plate 2 and four side plates 3. One of the side plates 3 has a wire outlet notch 4, which extends from the inside of the side plate 3 to the edge of the side plate 3 away from the top plate 2. Depending on the actual number of wiring harnesses, one or two wire outlet notches 4 are provided. This embodiment demonstrates the use of two wire outlet notches 4.

[0028] like Figure 8 As shown, a groove 6 is formed on the base plate 5. The groove 6 is adapted to the shape of the edges of the four side plates 3 of the outer shell 1. At the same time, a first sealing gasket 7 is provided in the groove 6. The four corners of the outer shell 1 are fixed to the base plate 5 by bolts 23. When the bolts 23 are tightened, the outer shell 1 can press the first sealing gasket 7 tightly into the groove 6, thereby achieving a sealed connection between the open edge of the outer shell 1 and the base plate 5.

[0029] To seal the outlet gap 4 and secure the wire, the fixing device provided in this invention includes a first sealing member 8 and a second sealing member 9, such as... Figure 6 As shown, the first sealing element 8 includes a first semi-ring 12 and a sealing plate 13 fixed to the first semi-ring 12. A first flange 14 is fixed to the edge of the sealing plate 13. The second sealing element 9 includes a second semi-ring 15, with a second flange 16 fixed to one end. The first semi-ring 12 and the second semi-ring 15 cooperate to form a wire-passing tube 17. Both the first semi-ring 12 and the second semi-ring 15 are provided with clearance openings for wires to pass through, and the two clearance openings are joined to form a circular wire-passing hole. Figure 6 and Figure 7 As shown, a groove 18 is provided on the mating surface of the first half-ring 12, and a locking block 19 is fixed on the mating surface of the second half-ring 15. A second sealing gasket 20 is provided in the groove 18. When the second half-ring 15 is fixed to the first half-ring 12, the locking block 19 presses the second sealing gasket 20 against the groove 18, thereby achieving a sealed connection between the first half-ring 12 and the second half-ring 15.

[0030] Since there are two gaps in the qualification process, such as... Figure 5 and Figure 6As shown, two fixing devices are also provided. The first flanges 14 of two adjacent first sealing members 8 are fixedly connected, and the second flanges 16 of two adjacent second sealing members 9 are also fixedly connected. The first sealing members 8 and the second sealing members 9 are fixed by bolts 23. At the same time, a third sealing gasket 21 is fitted on the edge of the second semi-ring 15 and the sealing plate 13, and a through hole 22 is opened in the side plate 3. When the first sealing member 8 is locked and fixed to the side plate 3 by a bolt 23 passing through the through hole 22, the first flanges 14 and the second flanges 16 cooperate to press the third sealing gasket 21 against the side plate 3, realizing the seal between the fixing device and the outlet notch 4. At the same time, a sealing ring is provided between the bolt 23 and the side plate 3 to seal the through hole 22.

[0031] With the above setup, the middle part of the wire can be placed on the clearance opening of the first sealing member 8, and then the second sealing member 9 is connected to the first sealing member 8 and locked with bolt 23 to allow the wire to pass through the through hole. Then, the first sealing member 8 and the second sealing member 9 are placed at the wire exit notch 4, and the first sealing member 8 is fixed to the side plate 3 with bolt 23. At this time, the third sealing gasket 21 can seal the part where the wire exit notch 4 intersects with the first sealing member 8 and the second sealing member 9, thus allowing the middle part of the wire to be placed into the through hole.

[0032] Example 2: Based on Embodiment 1, in order to fix the middle part of the wire in the wire hole and prevent the wire from shaking, this invention designs a wire harness clamping device, such as... Figure 6 As shown, the wire harness clamping device specifically includes two bosses fixed to the inner walls of the first half-ring 12 and the second half-ring 15, respectively. When the first half-ring 12 and the second half-ring 15 are mated, the two bosses join together to form a retaining ring 24. The wire harness clamping device also includes two mating halves, which cooperate to form a clamping sleeve 25, which is threaded into the wire threading tube 17. Several turns of elastic band 10 can be wound around the wire harness between the retaining ring 24 and the clamping sleeve 25. When the clamping sleeve 25 is rotated, the clamping sleeve 25 moves towards the retaining ring 24 and presses the elastic band 10, causing the elastic band 10 to clamp the wire harness. At the same time, the elastic deformation of the elastic band 10 can also seal the gaps between the wire harnesses. To further improve the sealing effect, sealant can also be injected into the clamped elastic band 10 to completely seal the wire threading hole.

[0033] Example 3: Based on Embodiments 1 and 2, to make it easier to align the threads of the two half-sets, as follows: Figure 6 As shown, teeth 11 are provided on the two halves for mating. By engaging the teeth 11 on the two halves, the two halves can be correctly mated to form a clamping sleeve 25.

[0034] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
