Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to an insulating and isolating inner baffle for a drive component. Background Technology

[0002] The drive system of new energy vehicles (such as motors, inverters, high-voltage wiring harnesses, etc.) involves high voltage (usually above 300V) and high current during operation, and requires electrical safety protection through insulating inner baffles.

[0003] In the existing technology, the inner baffle needs to be installed and positioned by bolts. When the baffle needs multiple fixing points, the time is long. At the same time, the bolt connection relies on the friction of the threads to resist vibration. Long-term vibration may cause the nuts to loosen, causing the insulation plate to shift or even fall off, which poses a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing technology uses bolts for installation and positioning, which is not only time-consuming, but also relies on the friction of the threads to resist vibration, which can lead to the loosening of the nuts and pose a safety hazard. Therefore, an insulating inner baffle for the drive component is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an insulating inner baffle for a driving component, comprising a baffle body, an anti-deformation mechanism installed inside the baffle body, insulating plates installed on both sides of the outer side of the baffle body, an installation mechanism installed on one side of one of the insulating plates, the installation mechanism comprising a fixing sleeve and a connecting sleeve, an installation block fixedly connected to one end of the fixing sleeve, the other end of the fixing sleeve being fixedly connected to one end of the connecting sleeve, a connecting block provided inside the connecting sleeve, one end of the connecting block being fixedly connected to one side of the insulating plate, a fixing block being fixedly connected to the other end of the connecting block, a positioning protrusion fixedly connected to the outer side of the fixing block, the positioning protrusion being disposed inside the fixing sleeve.

[0006] Preferably, a sliding groove is provided on the inner side of the sleeve.

[0007] Preferably, the end of the positioning protrusion abuts against a pressing block, and a telescopic rod is fixedly connected to the outside of the pressing block, with one end of the telescopic rod fixedly connected to the inside of the fixing sleeve.

[0008] Preferably, a compression spring is installed between the pressing block and the fixed sleeve, and the compression spring is sleeved on the outside of the telescopic rod.

[0009] Preferably, the anti-deformation mechanism includes a reinforcing frame, a second reinforcing rod fixedly connected to the middle of the reinforcing frame, a first reinforcing rod fixedly connected between the two second reinforcing rods, and a connecting diagonal rod fixedly connected at the inner corner of the reinforcing frame, with one end of the connecting diagonal rod fixedly connected to one side of the second reinforcing rod.

[0010] Preferably, the reinforcing frame is a hollow square frame, and there are two reinforcing frames, with a reinforcing block fixedly connected between the two reinforcing frames.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the end of the positioning protrusion is aligned with the sliding groove, the positioning protrusion slides into the inside of the fixed sleeve, and then the position of the insulating plate is rotated 90 degrees. The compression spring deforms, and when the end of the positioning protrusion rotates to the groove in the middle of the pressing block, the elastic force of the deformed compression spring pushes the two pressing blocks to engage with the outside of the positioning protrusion, so that the positioning protrusion forms circumferential and axial limiting, preventing the baffle body from loosening under vibration, impact and other working conditions. The operation process of directly rotating and engaging after positioning is greatly shortened and rapid assembly is achieved.

[0013] 2. In this utility model, the anti-deformation mechanism connects two sets of reinforcing frames through reinforcing blocks to support the baffle body as a whole. The hollow parts inside the reinforcing frames are supported by connecting diagonal rods. The second reinforcing rod and the first reinforcing rod increase the strength and improve the anti-deformation performance of the reinforcing frames, thereby improving the vibration resistance and impact resistance of the baffle body and preventing deformation failure under long-term working conditions.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides an insulating inner baffle for a driving component, including a baffle body 1. An anti-deformation mechanism 5 is installed inside the baffle body 1. Insulating plates 2 are installed on both outer sides of the baffle body 1. An installation mechanism 4 is installed on one side of one of the insulating plates 2. The installation mechanism 4 includes a fixing sleeve 41 and a connecting sleeve 42. One end of the fixing sleeve 41 is fixedly connected to an installation block 3, and the other end of the fixing sleeve 41 is fixedly connected to one end of the connecting sleeve 42. A connecting block 43 is provided inside the connecting sleeve 42, and one end of the connecting block 43 is fixedly connected to the insulating sleeve 42. On one side of the flange 2, a fixing block 44 is fixedly connected to the other end of the connecting block 43. A positioning protrusion 49 is fixedly connected to the outer side of the fixing block 44. The positioning protrusion 49 is located inside the fixing sleeve 41. A sliding groove 46 is provided on the inner side of the sleeve 42. A pressing block 47 is abutted against the end of the positioning protrusion 49. A telescopic rod 48 is fixedly connected to the outer side of the pressing block 47. One end of the telescopic rod 48 is fixedly connected to the inner side of the fixing sleeve 41. A compression spring 45 is installed between the pressing block 47 and the fixing sleeve 41. The compression spring 45 is sleeved on the outside of the telescopic rod 48.

[0022] The specific settings and functions of this embodiment are described below. The mounting block 3 is a component of the drive component housing. The end of the positioning protrusion 49 is aligned with the sliding groove 46. The positioning protrusion 49 slides inside the sleeve 42 to the inside of the fixed sleeve 41. Then, the position of the insulating plate 2 is rotated 90 degrees, so that the end of the positioning protrusion 49 pushes the two pressing blocks 47 outward. The compression spring 45 deforms, and the telescopic rod 48 retracts. When the end of the positioning protrusion 49 rotates to the groove in the middle of the pressing block 47, the elastic force of the deformed compression spring 45 pushes the two pressing blocks 47 to engage with the outside of the positioning protrusion 49, thereby positioning the positioning protrusion 49 and forming circumferential and axial limits. This prevents the baffle body 1 from loosening under vibration, impact, and other working conditions, and realizes the fixed connection between the baffle body 1 and the drive component housing. The operation process of directly rotating and engaging after alignment can be completed without additional tools, greatly shortening the assembly time and achieving rapid assembly.

[0023] Example 2: Figure 1 and Figure 4 As shown, the anti-deformation mechanism 5 includes a reinforcing frame 51, a second reinforcing rod 53 fixedly connected to the middle of the reinforcing frame 51, a first reinforcing rod 52 fixedly connected between the two second reinforcing rods 53, a connecting diagonal rod 55 fixedly connected at the inner corner of the reinforcing frame 51, and one end of the connecting diagonal rod 55 fixedly connected to one side of the second reinforcing rod 53; the reinforcing frame 51 is a hollow square frame, and two reinforcing frames 51 are provided, with a reinforcing block 54 fixedly connected between the two reinforcing frames 51.

[0024] The overall effect of this embodiment is that an anti-deformation mechanism 5 is installed inside the baffle body 1. The anti-deformation mechanism 5 is connected to two sets of reinforcing frames 51 through reinforcing blocks 54 to support the baffle body 1 as a whole. The hollow part inside the reinforcing frame 51 is supported by connecting diagonal rods 55. The second reinforcing rod 53 and the first reinforcing rod 52 increase the strength and improve the anti-deformation performance of the reinforcing frame 51, thereby improving the vibration resistance and impact resistance of the baffle body 1 and preventing deformation failure under long-term working conditions. At the same time, insulating plates 2 are provided on both sides of the outside of the baffle body 1 to improve the creepage distance and electrical clearance and ensure insulation.

[0025] The usage and working principle of this device are as follows: An anti-deformation mechanism 5 is installed inside the baffle body 1. This mechanism 5 connects two sets of reinforcing frames 51 via reinforcing blocks 54, providing overall support to the baffle body 1. The hollow sections inside the reinforcing frames 51 are diagonally supported by connecting diagonal rods 55. The second reinforcing rod 53 and the first reinforcing rod 52 increase strength and improve the anti-deformation performance of the reinforcing frames 51, thereby enhancing the vibration and impact resistance of the baffle body 1 and preventing deformation failure under long-term operating conditions. Simultaneously, insulating plates 2 are installed on both outer sides of the baffle body 1 to increase creepage distance and electrical clearance, ensuring insulation. During installation… Align the end of the positioning protrusion 49 with the sliding groove 46. The positioning protrusion 49 slides inside the sleeve 42 to the inside of the fixed sleeve 41. Then, rotate the position of the insulating plate 2 by 90 degrees, so that the end of the positioning protrusion 49 pushes the two pressing blocks 47 outward. The compression spring 45 deforms and the telescopic rod 48 retracts. When the end of the positioning protrusion 49 rotates to be positioned in the groove in the middle of the pressing block 47, the deformed compression spring 45 exerts its elastic force to push the two pressing blocks 47 to engage with the outside of the positioning protrusion 49, thereby positioning the positioning protrusion 49 and realizing the fixed connection between the baffle body 1 and the drive component housing, thus achieving rapid assembly.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
