Description
Technical Field
[0001] This utility model relates to the field of reducer housing technology, specifically a lightweight and high-rigidity electric vehicle reducer housing. Background Technology
[0002] As the core structure for power transmission and protection of internal components, the reducer housing of an electric vehicle must simultaneously meet the dual requirements of lightweight and high rigidity: lightweight design can effectively reduce the overall vehicle weight and reduce energy consumption to improve range; high rigidity can withstand high-frequency vibrations and instantaneous impacts generated during vehicle operation, prevent housing deformation or cracking, and ensure stable operation of internal transmission components.
[0003] When installing traditional housings on electric vehicles, they often rely on a single bolt for fixation, lacking interlocking positioning. This makes them prone to installation misalignment, and the connection is not very stable after installation. Vibrations during driving can easily cause the connection to loosen, which not only affects the transmission efficiency of the reducer but may also cause safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a lightweight and highly rigid electric vehicle reducer housing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight and high-rigidity electric vehicle reducer housing, comprising a reducer housing and an outer plate, wherein an assembly mechanism is provided on the outer plate and the suspension bracket, a stabilizing mechanism is provided on the assembly mechanism, reinforcing ribs are fixedly connected to the surface of the reducer housing, and flanges are fixedly connected to the front and rear sides of the reducer housing respectively. The assembly mechanism includes a plug-in component and a fixing component, wherein the fixing component is disposed on the top of the plug-in component; The plug-in assembly includes a through-hole groove, which is formed inside the suspension bracket. A long rod is inserted through the two through-hole grooves at the front and rear. The outer plate is sleeved on the surface of the long rod. Insertion slots are formed inside the front and rear sides of the long rod. Sliding grooves are formed around the inner circle of the insertion slots. Insert rods are inserted inside the insertion slots. Sliding plates are fixedly connected around the surface of the insertion rods. Connecting plates are fixedly connected to the left and right sides of the two insertion rods away from the suspension bracket. Locking plates are hinged to the left and right sides of the connecting plates. Locking blocks are fixedly connected to the locking plates near the suspension bracket. Locking slots are formed on the outer sides of the left and right suspension brackets.
[0006] Preferably, the slide plates and slide grooves are grouped into groups of four, and the interior of the slide grooves is slidably connected to the surface of the slide plates.
[0007] Preferably, there are four slots and four blocks, with the slot openings on the left and right sides corresponding to each other. The surface of the block and the inside of the slot are engaged. The insert rod is inserted into the insertion slot, the slide plate slides along the slide groove, and the block is engaged in the slot, completing the initial fixation of the suspension bracket and the outer plate, which makes it easy to install the reducer on the electric vehicle.
[0008] Preferably, the fixing component includes a fixing rod, which is fixedly connected to the top of the suspension bracket. A rotating plate is rotatably connected to the surface of the fixing rod. Nuts are fixedly connected to the inner sides of the outer plates on both sides. Rectangular grooves are opened at both ends of the outer sides of the outer plates on both sides. The rotating plate and the nuts are internally threaded with screws.
[0009] Preferably, there are four rectangular slots arranged in pairs. The outer sides of the rectangular slots on the front and rear sides and the outer sides of the rectangular slots on the left and right sides are set as openings. The surface of the rotating plate is inserted into the inside of the rectangular slot.

[0012] Compared with the prior art, this utility model provides a lightweight and high-rigidity electric vehicle reducer housing, which has the following advantages: 1. This lightweight and high-rigidity electric vehicle reducer housing, through an assembly mechanism, inserts a rod into the insertion slot, slides the slide plate along the slide groove, rotates the locking plates on both sides of the connecting plate, and makes the locking blocks on the inner side of the locking plates engage with the slots, completing the initial fixation of the suspension bracket and the outer plate, which can facilitate the installation of the reducer on the electric vehicle.

[0018] This utility model provides the following technical solution: Example 1 Combination Figures 1 to 4 A lightweight and high-rigidity electric vehicle reducer housing includes a reducer housing 2 and an outer plate 4. An assembly mechanism 3 is provided on the outer plate 4 and the suspension bracket 5. A stabilizing mechanism 6 is provided on the assembly mechanism 3. A reinforcing rib 1 is fixedly connected to the surface of the reducer housing 2. Flanges 7 are fixedly connected to the front and rear sides of the reducer housing 2 respectively. Assembly mechanism 3 includes a plug-in component 31 and a fixing component 32, with the fixing component 32 disposed on the top of the plug-in component 31; The plug-in assembly 31 includes a through-hole groove 3101, which is opened inside the suspension bracket 5. A long rod 313 is inserted through the two through-hole grooves 3101. The outer plate 4 is sleeved on the surface of the long rod 313. Insertion grooves 314 are opened inside the front and rear sides of the long rod 313. Sliding grooves 315 are opened around the inner circle of the insertion grooves 314. Insertion rods 312 are inserted inside the insertion grooves 314. Slide plates 311 are fixedly connected around the surface of the insertion rods 312. Connecting plates 316 are fixedly connected to the side of the left and right insertion rods 312 away from the suspension bracket 5. Locking plates 317 are hinged to the left and right sides of the connecting plates 316. Locking blocks 318 are fixedly connected to the side of the locking plates 317 near the suspension bracket 5. Locking grooves 319 are opened on the outer side of the left and right suspension brackets 5. The slide plate 311 and slide groove 315 are grouped into four. The inside of the slide groove 315 is slidably connected to the surface of the slide plate 311. There are four slots 319 and four blocks 318. The openings of the slots 319 on the left and right sides are correspondingly opened. The surface of the block 318 is engaged with the inside of the slot 319. The fixing component 32 includes a fixing rod 322, which is fixedly connected to the top of the suspension bracket 5. A rotating plate 325 is rotatably connected to the surface of the fixing rod 322. Nuts 324 are fixedly connected to the inner sides of the left and right outer plates 4. Rectangular slots 321 are opened at both ends of the outer sides of the left and right outer plates 4. Screws 323 are threadedly connected to the rotating plate 325 and the nuts 324. There are four rectangular slots 321, which are in pairs. The outer sides of the rectangular slots 321 on the front and rear sides and the outer sides of the rectangular slots 321 on the left and right sides are set as openings. The surface of the rotating plate 325 is inserted into the inside of the rectangular slots 321.
[0019] Furthermore, the insertion rod 312 is inserted into the insertion slot 314, the slide plate 311 slides along the slide groove 315, and the locking block 318 is locked into the locking slot 319, completing the initial fixation of the suspension bracket 5 and the outer plate 4, which makes it easy to install the reducer on the electric vehicle. The rotating plate 325 is inserted into the rectangular slot 321, and the screw 323 passes through the rotating plate 325 and is threadedly connected to the nut 324 on the inner side of the outer plate 4. After tightening the screw 323, the relative position of the suspension bracket 5 and the outer plate 4 is further locked to prevent loosening of the installation.
[0020] Example 2 See Figure 1-5 Furthermore, based on Embodiment 1, the stabilizing mechanism 6 includes a fixed base 63, which is fixedly connected to the inner ends of the front and rear connecting plates 316. A square groove 64 is provided inside the fixed base 63, and a square block 65 is inserted into the square groove 64. An X-shaped plate 61 is fixedly connected between the four square blocks 65. Screws 62 are threadedly connected to the square blocks 65 and the fixed base 63. There are four square grooves 64, and the top of the square groove 64 and the side away from the connecting plate 316 are set as openings.
[0021] Furthermore, the block 65 is inserted into the square groove 64, and the screw 62 is used to pass through the block 65 and the fixing seat 63 and tighten it to fix the X-shaped plate 61. The triangular structure formed by the X-shaped plate 61 and the connecting plate 316 can disperse the force transmitted by the reducer housing 2 and avoid deformation of the connection between the suspension bracket 5 and the outer plate 4. At the same time, the reinforcing rib 1 on the surface of the reducer housing 2 also enhances its own rigidity, ultimately achieving a stable installation.
[0022] Based on the "skeleton" obtained through topology optimization, a reinforcing rib system is designed on its foundation. This is not a simple uniform mesh rib, but a "variable density" and "variable height" reinforcing rib. Dense, thick radial or honeycomb reinforcing ribs are used to form a sturdy "force tower" to ensure support stiffness and suppress deformation and vibration. Sparse, thinner reinforcing ribs are used, mainly to increase the natural frequency of the wall panel and prevent resonance from generating noise, rather than being the main load-bearing rib.
[0023] The reinforcing ribs and main wall panels are smoothly transitioned with rounded corners to avoid stress concentration; the motor mounting flange, suspension bracket and other functional structures are integrally die-cast with the main housing to reduce the number of parts and connection weight; high-strength aluminum alloy materials are preferred to achieve maximum weight reduction while ensuring performance.
[0024] In actual operation, when this device is used, align the through hole groove 3101 of the suspension bracket 5 with the reserved hole of the outer plate 4, insert the long rod 313 through the front and rear through hole grooves 3101, so that the outer plate 4 is sleeved on the surface of the long rod 313, and complete the initial positioning of the two. Insert the plug rod 312 into the plug slot 314, slide the slide plate 311 along the slide groove 315, rotate the locking plates 317 on both sides of the connecting plate 316, so that the locking block 318 on the inner side of the locking plate 317 is engaged in the slot 319, and complete the initial fixation of the suspension bracket 5 and the outer plate 4, so that the reducer can be easily installed on the electric vehicle. Rotate the rotating plate 325 on the surface of the fixed rod 322 so that it is inserted into the rectangular groove 321. Pass the screw 323 through the rotating plate 325 and thread it with the nut 324 on the inner side of the outer plate 4. After tightening the screw 323, the relative position of the suspension bracket 5 and the outer plate 4 is further locked to prevent loosening of the installation. Insert the square blocks 65 around the X-shaped plate 61 into the square grooves 64, and tighten the screws 62 through the blocks 65 and the fixing base 63 to fix the X-shaped plate 61. The triangular structure formed by the X-shaped plate 61 and the connecting plate 316 can disperse the force transmitted by the reducer housing 2 and prevent deformation of the connection between the suspension bracket 5 and the outer plate 4. At the same time, the reinforcing ribs 1 on the surface of the reducer housing 2 also enhance its rigidity, ultimately achieving a stable installation.
