Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, specifically an internal insulation support for a high-voltage box in an electric vehicle. Background Technology

[0002] With the rapid development of the electric vehicle industry, the safety, stability and maintainability of the internal structure of the electric vehicle high-voltage box, as the core component for vehicle power transmission and distribution, are becoming increasingly critical. The insulating support base, as an important component in the high-voltage box to ensure electrical insulation and component stability, directly affects the overall performance of the high-voltage box through its connection method with the high-voltage box.

[0003] Currently, the traditional connection between the internal insulation support base and the high-voltage box of electric vehicles is mainly based on bolt fastening and adhesive fixing. When using bolt connection, it is necessary to accurately align the bolts and screw holes in the narrow space inside the high-voltage box and tighten them with tools. The operation process is cumbersome, which greatly increases the installation time and labor costs. Moreover, the continuous vibration and bumps that the vehicle is subjected to during driving can easily cause the bolts to loosen or even fall off, causing the high-voltage components to shift, which in turn can lead to serious safety accidents such as short circuits and leakage.

[0004] In addition, the existing insulating support connection structure is insufficient in terms of versatility, making it difficult to flexibly adapt to the installation requirements of high-voltage components of different specifications. At the same time, some structures are not good in terms of ease of operation, lacking a design that facilitates quick installation and disassembly, and cannot meet the requirements of efficient production and convenient maintenance of electric vehicles. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an internal insulation support for the high-voltage box of an electric vehicle. It solves the problems that the existing insulation support connection structure is not versatile enough to flexibly adapt to the installation requirements of high-voltage components of different specifications. At the same time, some structures are not good in terms of ease of operation and lack a design that facilitates quick installation and disassembly, thus failing to meet the requirements of efficient production and convenient maintenance of electric vehicles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an internal insulating support for a high-voltage box in an electric vehicle, comprising a high-voltage box base plate, a plurality of fixed bases fixedly connected to the top of the high-voltage box base plate, a support body placed at the bottom of the fixed bases, a pin fixedly connected to the bottom of the support body, a connecting plate provided inside the fixed base, a plurality of fixed blocks fixedly connected to the top of the connecting plate, a clamping block rotatably connected inside the fixed blocks, a threaded post threadedly connected inside the fixed base, a locking block fixedly connected to the bottom of the threaded post, the locking block having a frustum-shaped structure, the locking block being located outside the clamping block, and a slot for cooperating with the pin being opened inside the threaded post, the inner side of the clamping block being fixedly connected to the outer side of the pin, an adjusting plate being connected to the top of the threaded post, the support body being an insulating base, and a first screw threadedly connected to the top of the support body, with a nut threadedly connected to the outer side of the first screw.

[0007] As a further embodiment of this utility model: the top two sides of the fixed base are fixedly connected with protrusions in a symmetrical structure, the main body of the support base is located above the protrusions, and a second screw is threadedly connected between the main body of the support base and the protrusions.

[0008] As a further embodiment of this utility model: the adjusting disc is located between the protrusions, and a rubber pad is provided on the top of the protrusion.

[0009] As a further embodiment of this utility model: both the main body of the support base and the outer side of the fixed base are provided with slots for use with the adjustment plate.

[0010] As a further embodiment of this utility model: a coil spring is provided between the fixing block and the clamping block, and a rubber pad is provided on the inner side of the clamping block; the fixing base has an active groove for use with the clamping block.

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

[0012] 1. Unlike the traditional connection method that requires repeatedly tightening multiple bolts, the main body of the support base can be installed and disassembled by rotating the adjustment plate. The operation is extremely simple. In the environment of the narrow space inside the high-voltage box, this method greatly reduces the difficulty of operation, significantly shortens the installation and disassembly time, and effectively reduces labor costs. At the same time, during maintenance and repair, the main body of the support base can be quickly disassembled to facilitate the inspection and maintenance of the inside of the high-voltage box, thereby improving the overall work efficiency.

[0013] 2. The system employs a multi-layered fixing method, including clamping blocks and inserts for tight gripping, threaded pins for threaded connection to the fixed base, and protrusions for horizontal limiting. This ensures the main body of the support is securely connected to the fixed base, effectively resisting vibrations and bumps during vehicle operation and preventing loosening. Furthermore, the inclusion of rubber pads and coil springs not only buffers external impacts and reduces rigid collisions but also helps maintain clamping force, further enhancing the reliability of the connection. This provides stable support for high-voltage components, reduces safety hazards such as leakage and short circuits, and ensures the safe operation of the electric vehicle's high-voltage system.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-5 As shown, this utility model provides a technical solution:

[0022] An internal insulating support for a high-voltage box of an electric vehicle includes a high-voltage box base plate 1. Multiple sets of fixed bases 2 are fixedly connected to the top of the high-voltage box base plate 1. A support body 3 is placed at the bottom of the fixed base 2. A plug post 10 is fixedly connected to the bottom of the support body 3. A connecting plate 14 is provided inside the fixed base 2. Multiple sets of fixed blocks 15 are fixedly connected to the top of the connecting plate 14. A clamping block 13 is rotatably connected inside the fixing block 15. A threaded post 11 is threadedly connected inside the fixed base 2. A locking block 12 is fixedly connected to the bottom of the threaded post 11. The locking block 12 has a frustum-shaped structure and is located outside the clamping block 13. A slot 17 for cooperating with the plug post 10 is opened inside the threaded post 11. The inner side of the clamping block 13 is fixedly connected to the outer side of the plug post 10. An adjusting plate 6 is connected to the top of the threaded post 11. The support body 3 is an insulating base. A first screw 5 is threadedly connected to the top of the support body 3. A nut 4 is threadedly connected to the outer side of the first screw 5.

[0023] Specifically, the support body 3 is placed on the fixed base 2, with the insert 10 at the bottom of the support body 3 aligned with the slot 17 in the threaded post 11. At this time, the clamping block 13 is in its initial state, located inside the clamping block 12 and not yet tightly connected to the insert 10. The insert 10 is inserted into the slot 17, completing the initial positioning of the support body 3 on the fixed base 2, ensuring accurate relative positions and laying the foundation for subsequent tightening operations. The adjusting disc 6 is rotated, causing the threaded post 11 to rotate downwards within the fixed base 2. Due to the clamping block 11... 2 is a frustum-shaped structure located outside the clamping block 13. As the threaded post 11 descends, the clamping block 12 gradually presses the clamping block 13 inward, making the inner side of the clamping block 13 tightly and fixedly connected with the outer side of the insert post 10, thereby firmly fixing the support body 3 to the fixed base 2. At the top of the support body 3, the high-voltage components that need to be supported can be installed and fixed by the first screw 5 and the nut 4. According to the specific requirements of the high-voltage components, the height of the first screw 5 is adjusted, and then the nut 4 is tightened to achieve stable support for high-voltage components of different specifications. The support is supported by rotating the adjusting disc 6 in the opposite direction, causing the threaded column 11 to rotate upwards. The clamping block 12 rises accordingly, reducing the squeezing force on the clamping block 13. The clamping block 13 returns to its initial state, releasing the fixation on the insert column 10. At this time, the support body 3 can be easily removed from the fixed base 2 for maintenance and repair of the high-voltage box. Compared with the traditional bolt connection method, this structure can realize the installation and disassembly of the support body 3 by rotating the adjusting disc 6, eliminating the need to repeatedly tighten multiple bolts in a narrow space. This greatly simplifies the operation process, improves the installation and disassembly efficiency, and reduces labor and time costs. The clamping block 13 is tightly connected to the insert column 10 under the squeezing of the clamping block 12, which can effectively resist the external forces such as vibration and bumps during vehicle operation and prevent the support body 3 from loosening. At the same time, the threaded connection between the threaded column 11 and the fixed base 2 and the fastening method of the clamping block 13 form multiple fixing guarantees. Compared with some adhesive fixing methods that are easily affected by the environment and fail, the connection reliability is significantly improved, ensuring that the high-voltage components are stably supported in the high-voltage box and reducing safety hazards.

[0024] The top two sides of the fixed base 2 are fixedly connected with protrusions 7 in a symmetrical structure. The support body 3 is located above the protrusions 7. The support body 3 and the protrusions 7 are threadedly connected with a second screw 8. The adjustment plate 6 is located between the protrusions 7. A rubber pad is provided on the top of the protrusions 7.

[0025] Specifically, the fixed base 2 has symmetrical protrusions 7 on both sides of its top. The support body 3 is located above the protrusions 7 and is threadedly connected to the protrusions 7 by the second screw 8. This structure can limit and fix the support body 3 from both sides, preventing the support body 3 from shaking or displacing in the horizontal direction. In conjunction with the bottom connection structure, it further enhances the stability of the support body 3 after installation, ensuring that it can better support the components inside the high-voltage box. The top of the protrusions 7 is equipped with rubber pads. When the support body 3 is subjected to external impact or slight displacement due to vehicle vibration, the rubber pads can play a buffering role, reducing the rigid collision between the support body 3 and the protrusions 7, avoiding damage to both due to long-term friction or collision, and also reducing the noise generated by vibration, thus achieving a certain vibration reduction and noise reduction effect.

[0026] Both the main body 3 of the support base and the fixed base 2 have slots 9 on their outer sides for use with the adjustment plate 6. A coil spring is provided between the fixed block 15 and the clamping block 13, and a rubber pad is provided on the inner side of the clamping block 13. The fixed base 2 has a movable slot 16 for use with the locking block 12.

[0027] Specifically, the support body 3 and the fixed base 2 have slots 9 on their outer sides for use with the adjustment plate 6, allowing the adjustment plate 6 to be embedded therein. When rotating the adjustment plate 6, the operator's fingers can apply force more easily, and the adjustment plate 6 will not rotate arbitrarily due to external interference, which facilitates precise control of the lifting and lowering of the threaded column 11 and improves the smoothness of installation and disassembly operations. A coil spring is set between the fixed block 15 and the clamping block 13. When the threaded column 11 rises and the squeezing force of the clamping block 12 on the clamping block 13 disappears, the coil spring can make the clamping block 13 automatically reset, which is convenient for the next installation. At the same time, during vehicle operation, if subjected to external forces such as vibration, the elasticity of the coil spring can help the clamping block 13 maintain a certain clamping force on the insertion column 10, prevent the connection from loosening, and enhance the reliability of the structure.

[0028] The working principle of this utility model is as follows:

[0029] First, place the support body 3 on the fixed base 2, align the insert 10 with the slot 17 in the threaded post 11 and insert it to complete the initial positioning of the support body 3 on the fixed base 2, determine the relative position of the two, and provide a basis for subsequent fastening.

[0030] Secondly, rotating the adjusting disc 6 causes the threaded column 11 to rotate downwards within the fixed base 2, and the frustum-shaped clamping block 12 descends accordingly, pressing the outer clamping block 13 to move inwards, so that the inner side of the clamping block 13 tightly clamps the insert 10, and firmly fixes the support body 3 on the fixed base 2; at the same time, the first screw 5 and nut 4 at the top of the support body 3 can be adjusted in height and locked according to the specifications of the high-voltage components, so as to achieve stable support for different high-voltage components;

[0031] It is worth mentioning that the symmetrical protrusions 7 on the top of the fixed base 2 are connected to the support body 3 by the second screw 8, which limits and fixes them in the horizontal direction, enhancing stability; the rubber pad on the top of the protrusion 7 buffers the impact of external force, reducing rigid collisions and noise; the slots 9 on the outer sides of the support body 3 and the fixed base 2 facilitate the application of force and precise control by the adjustment plate 6; the coil spring between the fixed block 15 and the clamping block 13 assists the clamping block 13 in automatic reset and maintaining clamping force, further preventing the connection from loosening;

[0032] Finally, by rotating the adjusting disc 6 in the opposite direction, the threaded column 11 rises, the clamping force of the locking block 12 on the clamping block 13 decreases, and the coil spring restores the clamping block 13 to its initial state, releasing the fixation on the insertion column 10. The support body 3 can then be easily removed, facilitating maintenance and repair inside the high-voltage box.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
