Description

Technical Field

[0001] This utility model relates to the field of electrical protection technology, and more specifically, to an insulating protective component and a controller assembly and vehicle having the same. Background Technology

[0002] In the field of electrical protection technology, as the functions of electrical components become increasingly complex, the requirements for their heat dissipation performance and overload current capability are also increasing. Contact between different electrical components can easily trigger short circuit risks. Commonly used methods for isolating different electrical components have the following drawbacks:

[0003] 1. In order to meet certain protection level requirements, the gaps between electrical components are limited to a very small range. This increases the risk of electrical components coming into contact, which may lead to short circuits between the positive and negative poles, affect the normal operation of electrical components, and may even cause safety problems.

[0004] 2. Using plastic housings to isolate electrical components can prevent short circuits, but because plastic materials have poor heat dissipation performance, heat may not be able to dissipate for high-power electrical components, affecting the stability and lifespan of the components.

[0005] 3. Using insulating tape for isolation has the risks of low reliability and easy detachment, and is not easy to operate, making it unsuitable for electrical components that require long-term stable operation.

[0006] Therefore, no effective solution has yet been proposed to address the technical problem of balancing insulation protection and heat dissipation in electrical appliances in existing technologies. Utility Model Content

[0007] The main objective of this invention is to provide an insulating protective component and a controller assembly and vehicle having the same, in order to solve the problem in the prior art that it is difficult to balance insulation protection and electrical heat dissipation.

[0008] To achieve the above objectives, according to one aspect of the present invention, an insulating protective component is provided, comprising: an insulating shell having a receiving cavity having an open end, a through hole communicating with the outside being provided at the bottom of the receiving cavity, and at least one opening structure communicating with the outside being provided on the side wall of the receiving cavity; a cover having a blocking position for blocking the opening end and an opening position for opening the opening end; wherein the insulating shell and the cover are both made of insulating material.

[0009] Furthermore, the insulating housing also includes a partition disposed within the receiving cavity, which divides the receiving cavity into multiple receiving units. Multiple through holes are provided at the bottom of the receiving cavity, and each through hole corresponds to one of the receiving units.

[0010] Furthermore, the cover is rotatably connected to the insulating housing so that the cover can switch between a covered position and an open position.

[0011] According to another aspect of the present invention, a controller assembly is provided, the controller assembly including a controller body and the aforementioned insulating protective element.

[0012] Furthermore, the controller body also includes a metal housing and a connector. When the insulating protective component is connected to the metal housing, the connector extends into the receiving cavity through a through hole.

[0013] Furthermore, the outer wall of the insulating shell is provided with a first snap-fit ​​assembly, and the metal shell is provided with a second snap-fit ​​assembly. The insulating shell and the metal shell are detachably connected through the first snap-fit ​​assembly and the second snap-fit ​​assembly.

[0014] Furthermore, the outer wall of the insulating shell is provided with a limiting structure, and the metal shell is provided with a mating space. When the insulating shell and the metal shell are connected, at least part of the limiting structure extends into the mating space.

[0015] Furthermore, the metal housing is provided with positioning protrusions, and the bottom of the insulating housing is provided with positioning space. When the insulating housing is connected to the metal housing, at least part of the positioning protrusions extends into the positioning space.

[0016] Furthermore, when the insulating housing is connected to the metal housing, the edge of the through hole is positioned at a distance from the edge of the connector.

[0017] According to another aspect of the present invention, a vehicle is provided, the vehicle having a controller assembly, the controller assembly being the controller assembly described above.

[0018] By applying the technical solution of this utility model, the insulating shell is configured as a hollow structure with a receiving cavity.

The side wall of the receiving cavity also has an opening structure to facilitate heat dissipation of the internal protected component. At the same time, the cooperation between the cover and the insulating shell realizes the sealing and opening of the receiving cavity, thereby protecting the protected component while facilitating its installation and maintenance, and effectively preventing foreign objects from entering, meeting the requirements of waterproofing and improving the product protection level. When the cover is in the open position, technicians can easily inspect and repair the internal components, reducing the time and cost of maintenance.

[0035] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0036] Combination Figures 1 to 2 As shown, according to a specific embodiment of this application, an insulating protective element is provided.

[0037] Specifically, the insulating protective component includes an insulating shell 1 and a cover 12. The insulating shell 1 has a receiving cavity 11 with an open end 110. The bottom of the receiving cavity 11 has a through hole 111 communicating with the outside. The side wall of the receiving cavity 11 also has at least one opening structure 112 communicating with the outside. The cover 12 has a blocking position for blocking the opening end 110 and an opening position for opening the opening end 110. Both the insulating shell 1 and the cover 12 are made of insulating material.

[0038] Applying the technical solution of this embodiment, the insulating shell 1 is configured as a hollow structure with a receiving cavity 11. The protected component can extend into the receiving cavity 11 through the through hole 111. The insulating shell 1 uses insulating material, which can ensure the formation of an effective insulating layer between the protected component and external electrical components, reducing the risk of short circuits caused by contact between the protected component and external electrical components, and effectively reducing the scrap rate of the protected component. The side wall of the receiving cavity 11 is also provided with an opening structure 112, which can facilitate heat dissipation of the internal protected component. At the same time, the cover 12 cooperates with the insulating shell 1 to realize the sealing and opening of the receiving cavity 11, thereby protecting the protected component while facilitating its installation and maintenance, and effectively preventing foreign objects from entering, meeting the requirements of waterproofing and improving the product protection level. When the cover 12 is in the open position, technicians can easily inspect and repair the internal components, reducing the time and cost of maintenance. Applying the insulating protective component of this embodiment to the field of electrical protection technology can solve the problem of difficulty in balancing insulation protection and electrical heat dissipation in the prior art.

[0039] Furthermore, the insulating housing 1 also includes a partition 13 disposed within the receiving cavity 11. The partition 13 divides the receiving cavity 11 into multiple receiving units 113. Multiple through holes 111 are provided at the bottom of the receiving cavity 11, with each through hole 111 corresponding to one receiving unit 113. By dividing the receiving unit 113 into multiple independent receiving units 113 through the partition 13, each receiving unit 113 corresponds to one through hole 111. Utilizing the correspondence between the through holes 111 and the receiving units 113, independent installation and protection of multiple protected components are achieved, ensuring that the protected components do not interfere with each other and reducing faults caused by interference between protected components. Simultaneously, the partition 13 also enhances the internal structural support of the insulating housing 1, improving the rigidity and durability of the housing.

[0040] Specifically, the separator 13 is an insulating baffle, and the separator 13 is integrally formed with the insulating housing 1.

[0041] Furthermore, the cover 12 is rotatably connected to the insulating housing 1, allowing the cover 12 to switch between a covered position and an open position. The rotatable connection between the cover 12 and the insulating housing 1 enables convenient switching between the covered and open positions. In the covered position, the cover 12 completely covers the opening of the receiving cavity 11, preventing foreign objects from entering or liquids from splashing in, thus improving the overall protective capability of the insulating housing 1. In the open position, the cover 12 can be easily rotated to one side, facilitating the inspection or maintenance of the protected components inside.

[0042] In one embodiment of this application, the cover 12 is connected to the insulating shell 1 by a hinge. The hinge connection gives the cover 12 high strength and wear resistance, ensuring the stability and reliability of the insulating shell 1 after long-term use.

[0043] Furthermore, the edge shape of the through hole 111 is designed to match the cross-sectional shape of the protected component. Matching the edge shape of the through hole 111 with the cross-sectional shape of the protected component enables precise positioning and secure installation of the protected component. It should be noted that specialized sealing and fixing components, such as rubber sealing rings, sealant, gaskets, clips, or spring clips, can be added between the edge of the through hole 111 and the protected component to enhance waterproof and dustproof performance, while preventing loosening caused by vibration during vehicle operation.

[0044] Combination Figures 1 to 7 As shown, according to another specific embodiment of this application, a controller assembly is provided, which includes a controller body and the insulating protective element in the above embodiment.

[0045] By applying the insulating protective components described in the above embodiments to the controller assembly, the electrical isolation and protection performance of the insulating protective components can be utilized to improve the reliability and safety of the controller assembly. This allows the controller assembly to effectively avoid short-circuit risks while maintaining high-performance heat dissipation and overload high current requirements, thereby improving the protection level.

[0046] Specifically, the controller body also includes a metal housing 3 and a connector 2. When the insulating protective component is connected to the metal housing 3, the connector 2 extends into the receiving cavity 11 through the through hole 111.

[0047] In this embodiment, the connector 2 extends into the receiving cavity 11 through the through hole 111, ensuring the stability and insulation performance of the connector 2 within the metal housing 3. The insulating housing 1 uses insulating material, ensuring an effective insulating layer is formed between the metal housing 3 and the connector 2, preventing the risk of short circuits between the positive and negative terminals, reducing product scrap rate. Simultaneously, the opening structure 112 on the insulating housing 1 aids in heat dissipation without affecting the heat dissipation efficiency of the metal housing 3. The cooperation between the cover 12 and the insulating housing 1 allows for the sealing and opening of the receiving cavity 11, thus protecting the connector 2 while facilitating its installation and maintenance. It also effectively prevents foreign objects from entering, meeting the requirements for waterproofing and improving the protection level of electronic products. When the cover 12 is in the open position, technicians can easily inspect and repair the connector 2, reducing time and costs during maintenance.

[0048] Furthermore, such as Figure 3 , Figure 4As shown, the insulating housing 1 and the metal housing 3 are detachably connected. This detachable connection allows for convenient assembly and disassembly of the insulating housing 1 and the metal housing 3, facilitating the maintenance and upgrading of electronic products, improving their maintainability and upgradeability, and reducing maintenance costs. Furthermore, the detachable connection allows for the independent assembly of the insulating housing 1 during production and assembly, followed by its attachment to the metal housing 3, thus improving assembly efficiency and flexibility.

[0049] Optionally, the outer wall of the insulating housing 1 is provided with a first snap-fit ​​assembly, and the metal housing 3 is provided with a second snap-fit ​​assembly. The insulating housing 1 and the metal housing 3 are detachably connected through the first snap-fit ​​assembly and the second snap-fit ​​assembly. By providing mutually cooperating first and second snap-fit ​​assemblies (not shown in the figure), a stable connection between the insulating housing 1 and the metal housing 3 can be ensured. While achieving a detachable connection, the structural stability and protection performance of the controller assembly are improved, and the assembly process is simplified, reducing production costs. The first snap-fit ​​assembly and the second snap-fit ​​assembly include, but are not limited to, structures such as claws, slots, or spring clips.

[0050] Preferably, the outer wall of the insulating shell 1 is provided with a limiting structure 14, and the metal shell 3 is provided with a mating space 30. When the insulating shell 1 is connected to the metal shell 3, at least part of the limiting structure 14 extends into the mating space 30.

[0051] like Figures 1 to 3 As shown, the insulating housing 1 is provided with a limiting structure 14, and the metal housing 3 is provided with a mating space 30. When the insulating housing 1 and the metal housing 3 are connected, at least a portion of the limiting structure 14 extends into the mating space 30. Through the mating of the limiting structure 14 and the mating space 30, a stable connection between the insulating housing 1 and the metal housing 3 is ensured, improving the structural stability and protection performance of the controller assembly, while simplifying the assembly process and reducing production costs.

[0052] It should be noted that the limiting structure 14 can be in the form of a protrusion, a limiting pin, or a limiting post, and the mating space 30 can be set as a groove, a limiting slot, or a limiting hole that mates with the limiting structure 14. When the limiting structure 14 mates with the mating space 30, at least a portion of the limiting structure 14 extends into the mating space 30 to ensure accurate alignment of the insulating shell 1 in a fixed position and prevent accidental detachment.

[0053] It should be noted that the insulating shell 1 and the metal shell 3 can be connected solely through the engagement of the limiting structure 14 and the mating space 30, or solely through the engagement of the snap-fit ​​assembly, or simultaneously through the engagement of the limiting structure 14 and the mating space 30 and the snap-fit ​​assembly. The simultaneous use of the limiting structure 14, the mating space 30, and the snap-fit ​​assembly ensures that after the limiting structure 14 and the mating space 30 are aligned, the snap-fit ​​assembly can further securely fix the connection between the insulating shell 1 and the metal shell 3. In this embodiment, the engagement of the mating space 30 and the limiting structure 14 precisely controls the position of the insulating shell 1 relative to the metal shell 3, avoiding alignment deviations during the connection process; it provides additional mechanical fixation, ensuring a stable connection of the insulating shell 1 to the metal shell 3, reducing the risk of loosening or detachment due to vibration during vehicle operation; it makes the installation and removal of the insulating shell 1 simple and quick, improving assembly line efficiency, and also facilitating subsequent maintenance and inspection.

[0054] In another embodiment of this application, such as Figure 8 As shown, the insulating housing 1 does not have a limiting structure 14, and the metal housing 3 does not have a mating space 30. There are no snap-fit ​​components between the insulating housing 1 and the metal housing 3; they are directly connected by adhesive. By directly bonding the insulating housing 1 to the metal housing 3 through adhesive at their contact surfaces, the insulating housing 1 is fixed to the metal housing 3, achieving the technical effects of enhanced sealing and improved connection stability. It should be noted that when using adhesive or other bonding materials, materials with good temperature resistance and insulation should be selected to ensure the vehicle maintains long-term stability in complex operating environments. Furthermore, the choice of insulation properties can prevent short circuits between the connector 2 and the metal housing 3, improving safety.

[0055] In one exemplary embodiment of this application, such as Figures 5 to 7 As shown, the metal housing 3 has a mounting groove 32, and the bottom of the mounting groove 32 has a mounting opening 320 for the connector 2 to pass through. When the insulating housing 1 is connected to the metal housing 3, the insulating housing 1 is located in the mounting groove 32. The mounting groove 32 is provided on the metal housing 3, and the size and shape of the mounting groove 32 should match the outer contour of the insulating housing 1 so that the insulating housing 1 can be accurately embedded in the mounting groove 32 to form a stable closed structure to isolate the connector 2 and the metal housing 3 and avoid short circuits. By tightly connecting the insulating housing 1 and the metal housing 3 through the mounting groove 32, the stability of the connector 2 during operation can be ensured, and the risk of connection loosening caused by vibration or impact can be reduced. At the same time, the design of the mounting groove 32 also helps to improve the protection level of the overall structure.

[0056] In this embodiment, the combined design of the mounting groove 32 and the mounting opening 320 can effectively isolate the connector 2 from the metal housing 3, avoid the risk of short circuit caused by the grounding effect of the metal housing 3, and improve the electrical safety of the insulating housing 1.

[0057] Furthermore, the metal housing 3 is provided with positioning protrusions 31, and the bottom of the insulating housing 1 is provided with positioning space. When the insulating housing 1 is connected to the metal housing 3, at least a portion of the positioning protrusions 31 extend into the positioning space. The positioning protrusions 31 facilitate rapid positioning during the assembly of the insulating housing 1. Multiple positioning protrusions 31 can be provided to improve assembly efficiency. The bottom of the insulating housing 1 is provided with a corresponding positioning space (not shown in the figure), which can be a positioning hole, positioning groove, etc.

[0058] Furthermore, when the insulating housing 1 is connected to the metal housing 3, the edge of the through hole 111 is positioned at a distance from the edge of the connector 2. This arrangement facilitates the assembly process and avoids interference caused by the edge of the through hole 111 being too close to the edge of the connector 2.

[0059] It should be noted that the distance between the edge of the through hole 111 and the edge of the connector 2 should not be too large to avoid foreign objects falling into the gap and affecting the normal operation of the connector 2. After the insulating housing 1 is connected to the metal housing 3, a special sealing and fixing component, such as a rubber sealing ring, sealant, gasket, clip, or spring clip, can be added between the edge of the through hole 111 and the edge of the connector 2 to enhance the waterproof and dustproof effect, while preventing loosening caused by vibration during vehicle operation.

[0060] In one exemplary embodiment of this application, the controller component is a Tail Domain Control Unit (TDCU). The TDCU integrates numerous functions such as power input, tailgate control, external lighting control, and air suspension, with a power consumption exceeding 80W, requiring heat dissipation through the metal housing 3. Simultaneously, to support the operation of these numerous functions, a high current input of over 100A is needed. Typically, a threaded post connector is used for current input, which is fixed to the circuit board by welding or crimping to provide power input. Furthermore, to meet the IP5K2 protection rating, the metal housing 3 is often placed very close to the connector 2 (threaded post in this embodiment), with a maximum gap of 1.0mm. This easily leads to contact between the threaded post and the metal housing 3. Since the metal housing 3 also serves as a grounding layer, if the positive terminal of the threaded post short-circuits with the negative terminal of the metal housing, it can not only render the entire tail domain controller unusable but may even cause a vehicle safety accident.

[0061] In this embodiment, an insulating protective component as described in the previous embodiment is added. Specifically, an insulating shell 1 is added between the metal shell 3 and the threaded post. Specifically, the insulating shell 1 is an insulating plastic shell, with a space left in the middle for the threaded post, allowing the insulating plastic shell to isolate the metal shell 3 from contact with the threaded post. The insulating plastic shell is designed for snap-fit ​​assembly, allowing for convenient assembly with the metal shell 3. The assembly sequence can be arranged according to the actual production line conditions. The insulating plastic shell is designed with a cover 12, which is connected to the insulating shell 1 via a hinge, realizing a flip-top function. It is injection molded as a single piece. The cover 12 can shield the threaded post, preventing foreign objects from entering the insulating shell 1, and also serves to prevent water droplets. Multiple partitions 13 are provided inside the insulating shell 1 to form multiple receiving units 113, each receiving unit 113 corresponding to a connector 2 (threaded post in this embodiment). The insulating shell 1 is integrally molded to improve the structural integrity and material uniformity of the insulating shell 1, and to enhance its electrical isolation performance and structural strength.

[0062] Preferably, the assembly gap between the metal housing 3 and the insulating plastic housing is ≤1.0mm. The dimensions of the insulating plastic housing need to be designed according to the number and arrangement of the selected threaded posts. A clearance needs to be provided between the insulating plastic housing and the threaded posts for tooling assembly when tightening the nuts.

[0063] According to another specific embodiment of this application, a vehicle is provided, the vehicle having a controller assembly, the controller assembly being the controller assembly in the above embodiments.

[0064] As can be seen from the above description, the above embodiments achieve the following technical effects:

[0065] 1) By adding an insulating housing 1 between the metal housing 3 and the high-current connector, the risk of short circuit is effectively avoided.

[0066] 2) The precise fit and integral molding design of the insulating shell and the metal shell significantly enhance the sealing performance and protection level of the overall structure, meeting the IP5K2 or higher protection requirements of automotive electronic products and effectively resisting the adverse effects of the external environment.

[0067] 3) The addition of the insulating shell 1 increases the structural complexity, but the heat dissipation performance is not affected by the retention of the metal shell 3. The metal shell 3 can still provide efficient heat dissipation and meet the heat dissipation requirements.

[0068] 4) With snap-fit ​​components and one-piece molding technology, the installation of the insulating housing 1 becomes simple and quick, without the need for complicated fixing processes, reducing the complexity and cost of the assembly line.

[0069] 5) The design of the mounting groove 32 and the limiting structure 14 ensures the precise alignment and stable connection of the insulating shell 1 on the metal shell 3, reduces the risk of connection loosening due to vibration or impact, and improves the stability and reliability of the connector 2.
