Abstract
Description
Technical Field
[0001] This utility model relates to the field of power controllers, and more particularly to a highly integrated power controller. Background Technology
[0002] In the field of power control, as electronic devices develop towards miniaturization and intelligence, higher requirements are placed on the integration, stability, and ease of installation of power controllers. Existing power controllers mainly suffer from the following technical bottlenecks in practical applications:
[0003] Fixed stability defects
[0004] Existing power controller installation methods mostly rely on single bolt connections or snap-fit structures, which are prone to loosening in vibrating environments (such as vehicle movement and industrial equipment operation). For example, traditional bolt connections achieve fixation solely through thread engagement, lacking anti-loosening design. Long-term vibration may cause bolts to fall off or strip, leading to power controller displacement or even detachment, causing equipment failure. Some snap-fit structures, due to material fatigue or insufficient installation precision, cannot provide sustained and stable clamping force, especially in high-frequency vibration scenarios, significantly increasing the risk of fixation failure.
[0005] Based on this, we propose a highly integrated power controller. Utility Model Content
[0006] To address the technical problem of power controllers being easily loosened, this invention provides a highly integrated power controller.
[0007] This utility model is achieved using the following technical solution: A highly integrated power controller includes a fixed base, with an ear plate integrally extending outward from the bottom end of the fixed base. The ear plate has ear plate holes on its surface. The ear plates are symmetrically distributed on both sides of the bottom end of the fixed base. The ear plate holes are circular through holes, and the axes of the two ear plate holes are parallel to each other. The ear plates are fixed by bolts. A threaded hole is formed on the surface of the fixed base, through which a fixing bolt passes. A slot is formed on the inner side of the fixed base, and a locking block is slidably engaged on the inner side of the slot. The locking block is mounted on the surface of a fixed plate. A fixing hole is formed on the side of the fixed plate, and a locking mechanism is mounted above the fixed plate. An internal thread is formed on the inner wall of the fixing hole, matching the threaded hole. The fixing bolt thread passes through both the fixed base and the fixed plate.
[0008] The engagement and fixing mechanism includes a lower boss, a protrusion fixedly installed on the upper surface of the lower boss, a threaded hole through the surface of the lower boss, a bolt post threadedly connected to the inner side of the threaded hole, an upper concave platform fixedly connected to the top of the bolt post, a notch opened on the surface of the upper concave platform, a bolt sleeve installed on the bolt post, and a power controller box fixedly connected to the back of the upper concave platform by bolts, with wires extending outward from the power controller box.
[0009] As a further optimization of this utility model, the ear plates at the bottom of the fixed base are bolted to the external structure (such as the equipment frame) through the ear plate holes. The ear plates are symmetrically distributed on both sides of the bottom of the fixed base, and the ear plate holes are circular through holes with parallel axes. The ear plates are fixed by bolts to achieve horizontal installation and foundation support of the fixed base.
[0010] As a further optimization of this utility model, the length of the fixing bolt is greater than the thickness of the fixing seat, and its thread length covers the depth of the threaded hole and the fixing hole, ensuring that the bolt completely penetrates and fills the thread gap. By extending the thread engagement length, the risk of bolt loosening or stripping under vibration is reduced.
[0011] As a further optimization of this utility model, the locking block on the surface of the fixing plate slides and engages with the locking groove on the inner side of the fixing seat. The cooperation between the locking groove and the locking block restricts the lateral movement of the fixing plate, completes the initial positioning, and provides guidance for subsequent bolt fixing.
[0012] As a further optimization of this utility model, the threaded hole of the fixing seat is aligned with the fixing hole of the fixing plate, and the thread of the fixing bolt passes through both. The inner wall of the fixing hole is provided with internal threads, forming a double thread engagement with the threaded hole, thereby enhancing the connection strength.
[0013] As a further optimization of this utility model, a bolt sleeve is installed on the outside of the bolt column. The axial clamping force of the bolt sleeve further locks the threaded connection between the bolt column and the lower boss, preventing the bolt column from rotating and loosening due to vibration, and enhancing the connection stability.
[0014] As a further optimization of this utility model, the power controller housing is fixed to the back of the upper recessed platform with bolts and connected to the fixing plate via an interlocking fixing mechanism. The entire structure forms a rigid connection system through multiple anti-loosening designs, effectively resisting the risk of displacement under vibration environment and solving the technical defects of traditional single bolt or buckle structures that are prone to loosening.
[0015] As a further optimization of this utility model, the protrusion is triangular prism-shaped, and the recess is a triangular prism-shaped groove, with the protrusion fitting into the interior of the recess. When the bolt is threadedly connected to the lower boss through the screw hole, the protrusion is embedded in the recess, forming a mechanical interlocking structure that restricts the relative rotation and displacement of the upper recess and the lower boss, providing vibration resistance and anti-loosening capability.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model uses the triangular prism-shaped protrusions and recesses of the interlocking fixing mechanism to form a mechanical interlock, which restricts the relative rotation of the upper and lower protrusions. Combined with the axial clamping force of the bolt sleeve, it constructs a double anti-loosening mechanism of "threaded connection + physical engagement", which can withstand high-frequency vibration (such as vehicle driving and industrial equipment operation). The anti-loosening effect is significantly better than that of traditional structures.
[0018] 2. This utility model achieves basic bolt installation through the ear plate and ear plate hole of the fixed seat, and forms a "basic support + pre-positioning" dual fixing system by sliding engagement between the fixing plate's locking block and the fixing seat's locking groove. This avoids the displacement risk of traditional single bolts or clips and is suitable for stable installation in vibration environments.
[0019] 3. This utility model uses a fixing bolt that passes through the threaded hole of the fixing seat and the fixing hole of the fixing plate. The double internal thread engagement extends the contact length, and the bolt length covers the hole depth, filling the thread gap. This effectively resists loosening or stripping caused by vibration. Compared with the traditional single thread connection, the connection reliability is significantly improved.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example 1:
[0027] Please combine Figures 1-3 This embodiment proposes a highly integrated power controller, including a fixed base 1. An ear plate 2 extends outward from the bottom end of the fixed base 1. An ear plate hole 3 is opened on the surface of the ear plate 2. The ear plates 2 are symmetrically distributed on both sides of the bottom end of the fixed base 1. The ear plate hole 3 is a circular through hole, and the axes of the two ear plate holes 3 are parallel to each other. The ear plates 2 are fixed by bolts.
[0028] In the specific technical solution, the ear plate 2 at the bottom of the fixed base 1 is bolted to the external structure (such as the equipment frame) through the ear plate hole 3. The ear plates 2 are symmetrically distributed on both sides of the bottom of the fixed base 1, and the ear plate hole 3 is a circular through hole with parallel axes. The ear plates 2 are fixed by bolts to achieve horizontal installation and foundation support of the fixed base 1.
[0029] The surface of the fixing seat 1 is provided with a threaded hole 5, and a fixing bolt 6 passes through the internal thread of the threaded hole 5. The length of the fixing bolt 6 is greater than the thickness of the fixing seat 1.
[0030] The inner side of the fixing base 1 has a slot 11, and a locking block 71 is slidably engaged inside the slot 11. The locking block 71 is installed on the surface of the fixing plate 7. The side of the fixing plate 7 has a fixing hole 72, and the interlocking fixing mechanism 8 is installed above the fixing plate 7. The inner wall of the fixing hole 72 has an internal thread, and the fixing hole 72 matches the threaded hole 5. The fixing bolt 6 is threaded through the fixing base 1 and the fixing plate 7.
[0031] More specifically, the locking block 71 on the surface of the fixing plate 7 slides and engages with the locking groove 11 on the inner side of the fixing seat 1. The engagement between the locking groove 11 and the locking block 71 restricts the lateral movement of the fixing plate 7, completing the initial positioning and providing guidance for subsequent bolt fixing. The threaded hole 5 of the fixing seat 1 is aligned with the fixing hole 72 of the fixing plate 7, and the fixing bolt 6 is threaded through both. The inner wall of the fixing hole 72 is provided with internal threads, forming a double thread engagement with the threaded hole 5, enhancing the connection strength. Furthermore, the thread length of the fixing bolt 6 covers the depth of both the threaded hole 5 and the fixing hole 72, ensuring that the bolt completely penetrates and fills the thread gap. By extending the thread engagement length, the risk of bolt loosening or stripping under vibration is reduced.
[0032] The interlocking and fixing mechanism 8 includes a lower boss 81, a protrusion 82 fixedly installed on the upper surface of the lower boss 81, a threaded hole 83 through the surface of the lower boss 81, a bolt post 84 threadedly connected to the inner side of the threaded hole 83, an upper recess 85 fixedly connected to the top of the bolt post 84, a notch 86 opened on the surface of the upper recess 85, a bolt sleeve 87 installed in matching with the bolt post 84, and a bolt sleeve 87 installed in matching with the outer side of the bolt post 84. Through the axial clamping force of the bolt sleeve 87, the threaded connection between the bolt post 84 and the lower boss 81 is further locked, preventing the bolt post 84 from rotating and loosening due to vibration, and strengthening the connection stability.
[0033] The back of the upper recessed platform 85 is bolted to a power controller housing 9, with wires extending outward from the power controller housing 9. The power controller housing 9 is bolted to the back of the upper recessed platform 85 and connected to the fixing plate 7 via an interlocking fixing mechanism 8. The entire structure, through multiple anti-loosening designs, forms a rigid connection system, effectively resisting the risk of displacement under vibration, and solving the technical defects of traditional single bolt or snap-fit structures that are prone to loosening.
[0034] In a further technical solution, the protrusion 82 is triangular prism-shaped, and the recess 86 is a triangular prism-shaped groove, with the protrusion 82 fitting into the interior of the recess 86. When the bolt post 84 is threadedly connected to the lower boss 81 through the screw hole 83, the protrusion 82 is embedded in the recess 86, forming a mechanical interlocking structure that restricts the relative rotation and displacement of the upper recess 85 and the lower boss 81, providing vibration resistance and anti-loosening capability.
[0035] This patent achieves stable installation and anti-loosening of the power controller through multi-structure collaboration. Its working principle is as follows:
[0036] Basic installation and preliminary positioning
[0037] The ear plates 2 at the bottom of the fixed base 1 are bolted to the external structure (such as the equipment frame) through the ear plate holes 3. The ear plates 2 are symmetrically distributed on both sides of the bottom of the fixed base 1, and the ear plate holes 3 are circular through holes with parallel axes. The ear plates 2 are fixed by bolts to achieve horizontal installation and foundation support of the fixed base 1.
[0038] The locking block 71 on the surface of the fixing plate 7 slides and engages with the locking groove 11 on the inner side of the fixing seat 1. The engagement between the locking groove 11 and the locking block 71 restricts the lateral movement of the fixing plate 7, completes the initial positioning, and provides guidance for subsequent bolt fixing.
[0039] The threaded hole 5 of the fixing base 1 is aligned with the fixing hole 72 of the fixing plate 7, and the fixing bolt 6 is threaded through both. The inner wall of the fixing hole 72 is provided with internal threads, which form a double thread engagement with the threaded hole 5 to enhance the connection strength.
[0040] Anti-loosening design
[0041] The length of the fixing bolt 6 is greater than the thickness of the fixing seat 1, and its thread length covers the depth of the threaded hole 5 and the fixing hole 72, ensuring that the bolt completely penetrates and fills the thread gap. By extending the thread engagement length, the risk of bolt loosening or stripping under vibration is reduced.
[0042] The protrusion 82 on the surface of the lower boss 81 is triangular prism-shaped, and the recess 86 on the surface of the upper concave platform 85 is a corresponding triangular prism-shaped slot. When the bolt post 84 is threadedly connected to the lower boss 81 through the bolt hole 83, the protrusion 82 is embedded in the recess 86, forming a mechanical interlock structure, which restricts the relative rotation and displacement of the upper concave platform 85 and the lower boss 81, and provides vibration resistance and anti-loosening capability.
[0043] A bolt sleeve 87 is installed on the outside of the bolt column 84. The axial clamping force of the bolt sleeve 87 further locks the threaded connection between the bolt column 84 and the lower boss 81, preventing the bolt column 84 from rotating and loosening due to vibration, and strengthening the connection stability.
[0044] Overall fixing of the power controller box
[0045] The power controller housing 9 is fixed to the back of the upper recessed platform 85 by bolts and connected to the fixing plate 7 via the interlocking fixing mechanism 8. The entire structure forms a rigid connection system through multiple anti-loosening designs, effectively resisting the risk of displacement under vibration environment and solving the technical defects of traditional single bolt or buckle structures that are prone to loosening.
[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
