Description

Technical Field

[0001] This utility model relates to the field of electric control braking technology for vehicles, specifically to a fixed structure and a solenoid valve assembly module having the fixed structure. Background Technology

[0002] With the rapid development of automotive electrification, intelligence, and connectivity, the Electronic Control Unit (ECU) has become a core component of modern automobiles. This is especially true for critical modules such as the braking system and transmission control within the ECU. The ECU comprises a control board, a mounting structure for the solenoid valve coils, and a protective housing. These components are fixed to the hydraulic control unit (HCU) via bolts or other connection methods. The mounting structure of the solenoid coils directly affects the reliability, vibration resistance, and assembly efficiency of the solenoid valves. In related technologies, the elastic support in the mounting structure, due to its low integration, is prone to fatigue fracture under external impacts and vibrations. Utility Model Content

The other end of the spring portion can abut against a fixing seat, and the snap-fit ​​portion can engage with the fixing seat. It is understood that both the spring portion and the snap-fit ​​portion cooperate with the fixing seat.

[0006] The solenoid valve coil fixing structure of this utility model embodiment is formed by integrally bending each of the snap-fit ​​part and the spring piece part onto the connecting bridge.

This improves the service life of the overall fixing structure.

[0007] Furthermore, the spring-loaded part with the elastic support can elastically contact the fixed base, thereby enabling the floating assembly of the solenoid valve coil and compensating for part of the height clearance between the winding bobbin assembly and the solenoid valve. This improves the applicability of the assembly.

[0014] In some embodiments, the connecting bridge is a ring plate with a clearance notch, and a portion of the winding skeleton assembly extends from the clearance notch.

[0015] In some embodiments, the winding bobbin assembly includes a housing, a bobbin body, an end cap, and a terminal block.

[0016] In some embodiments, the terminal block includes a buffer portion and two conductive portions respectively connected to both ends of the buffer portion, one of the conductive portions being electrically connected to the skeleton body and the other conductive portion being electrically connected to the control substrate. The buffer portion is bent in a zigzag shape to provide buffer space for the offset of the skeleton body relative to the control substrate.

[0017] In some embodiments, the skeleton body includes a cylindrical portion and baffle portions extending outward from the outer periphery at both ends of the cylindrical portion. An electromagnetic coil is wound on the cylindrical portion. The baffle portions abut against the inner peripheral wall of the housing. An end cap is disposed on one of the baffle portions.

[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is for reference. Figures 1-7 This invention describes the fixing structure 100 of the solenoid valve coil and the solenoid valve assembly module of an embodiment of the present invention.

[0037] The fixing structure 100 of the solenoid valve coil in this embodiment of the present invention includes a winding frame assembly 1 and an elastic bracket 2. The elastic bracket 2 includes a connecting bridge 21, a snap-fit ​​portion 22, and a spring portion 23. Each of the snap-fit ​​portion 22 and the spring portion 23 is integrally bent and formed on the connecting bridge 21. The connecting bridge 21 is fixed to the winding frame assembly 1. The other end of the spring portion 23 can abut against the fixing seat 200, and the snap-fit ​​portion 22 can engage with the fixing seat 200. It can be understood that both the spring portion 23 and the snap-fit ​​portion 22 cooperate with the fixing seat 200.

[0038] The solenoid valve coil fixing structure 100 of this embodiment of the invention is formed by integrally bending each of the snap-fit ​​part 22 and the spring piece part 23 onto the connecting bridge 21. This integral bending structure has good overall integrity, thereby reducing stress concentration in the elastic bracket 2 and lowering the maintenance frequency of the elastic bracket 2. As a result, the service life of the overall fixing structure 100 is improved.

[0039] Furthermore, the spring piece 23 of the elastic bracket 2 can elastically contact the fixed base 200, thereby enabling the floating assembly of the solenoid valve coil and compensating for part of the height gap between the winding bobbin assembly 1 and the solenoid valve assembly module. This improves the applicability of the assembly.

[0040] Therefore, the fixing structure 100 of the solenoid valve coil in this embodiment of the present invention has the advantages of long service life and good applicability.

[0041] For example, Figure 1 As shown, the spring piece 23 can provide an upward force to the fixing seat 200, and the latching part 22 can provide a downward force to the fixing seat 200. The fixing seat 200 can be a plastic shell, specifically, the fixing structure 100 is limited and floated by the elastic bracket 2.

[0042] The elastic bracket 2 is a metal elastic bracket 2. Because metal has a relatively high elastic modulus and more stable physical properties, it is more stable than plastic, thus further reducing the maintenance frequency of the elastic bracket 2. This further improves the service life of the fixing structure 100.

[0043] Optionally, the elastic support 2 can be a phosphor bronze support or a stainless steel support.

[0044] Furthermore, the thickness of the elastic support 2 is 0.2mm-0.5mm. For example, the thickness of each of the connecting bridge 21, the snap-fit ​​portion 22, and the spring portion 23 is 0.2mm-0.5mm. This avoids the problem of the fixing structure 100 being bulky and wasteful of materials due to excessive thickness of the elastic support 2, while also avoiding the problem of deformation caused by insufficient thickness of the elastic support 2. Therefore, the fixing structure 100 of the solenoid valve coil of this embodiment has the advantages of good structural stability and lightweight design.

[0045] Optionally, the thickness of the elastic support 2 can be 0.2mm, 0.3mm, 0.4mm and 0.5mm.

[0046] Optionally, the connecting bridge 21, the snap-fit ​​part 22, and the spring piece part 23 are integrally stamped. Therefore, the integrally stamped elastic bracket 2 has the advantages of good structural integrity and high ease of processing.

[0047] like Figure 1 and Figure 3 As shown, the spring piece 23 can be wavy or arc-shaped. For example, the spring piece 23 can be along... Figure 1 As shown, it extends upwards. That is, the spring piece 23 can be formed by bending the outer periphery of the connecting bridge 21 outwards. Thus, the spring piece 23 has the advantages of simple structure and good cushioning effect.

[0048] like Figure 1 and Figure 3 As shown, there are multiple latching parts 22, which are spaced apart along the circumference of the winding skeleton assembly 1. Each latching part 22 has a latching hole that can engage with the fixing seat 200.

[0049] The fixing structure 100 for the solenoid valve coil in this embodiment of the invention improves the stability of the connection between it and the fixing base 200 by providing multiple snap-fit ​​parts 22. This further enhances the overall stability of the fixing structure 100.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, the connecting bridge 21 is a ring plate with a clearance notch 211, and a portion of the winding skeleton assembly 1 extends from the clearance notch 211. By setting the connecting bridge 21 as a ring plate and providing the clearance notch 211 on the ring plate, the assembly of the winding skeleton assembly 1 is facilitated.

[0051] like Figures 1 to 6As shown, the winding frame assembly 1 includes a housing 11, a frame body 12, an end cap 13, and a terminal block 14. The frame body 12 is used to wind the electromagnetic coil and is disposed inside the housing 11. The end cap 13 is fitted onto one end of the frame body 12. A connecting bridge 21 is fixed to the outer surface of the end cap 13. One end of the terminal block 14 can be connected to the electromagnetic coil, and the other end of the terminal block 14 passes through the connecting bridge 21 and the end cap 13. The terminal block 14 is electrically connected between the frame body 12 and the control board of the solenoid valve assembly module.

[0052] The fixing structure 100 of the solenoid valve coil in this embodiment of the utility model can improve structural stability by dividing the winding skeleton assembly 1 into a housing 11, a skeleton body 12, an end cover 13 and a terminal block 14, and fixing the connecting bridge 21 to the outer side of the end cover 13.

[0053] Furthermore, the terminal 14 is specifically a PIN pin, which is sequentially inserted into the end cover 13 and the elastic bracket 2. The PIN pin and the through hole are in clearance fit, and the PIN pin is also electrically connected to the control board.

[0054] like Figure 1 and Figure 2 As shown, the terminal block 14 includes a buffer portion 141 and two conductive portions 142 respectively connected to both ends of the buffer portion 141. One conductive portion 142 is electrically connected to the frame body 12, and the other conductive portion 142 is electrically connected to the control board. The buffer portion 141 is arranged in a zigzag bend, and the zigzag bend structure provides buffer space for the offset of the frame body 12 relative to the control board.

[0055] The solenoid valve coil fixing structure 100 of this embodiment divides the terminal block 14 into a buffer portion 141 and two conductive portions 142 respectively connected to both ends of the buffer portion 141. The buffer portion 141 is bent in a zigzag shape to provide buffer space for the offset of the frame body 12 relative to the control substrate. The elastic deformation can ensure that the solenoid coil assembly floats up and down along the height direction of the coil frame, thereby realizing the floating assembly of the frame body 12 in the vertical direction. It can also buffer the vibration and impact transmitted to the frame body 12 through its own elastic deformation, avoiding large positional displacement of the frame body 12 under the action of vibration and impact, thereby reducing the maintenance frequency and use cost of the fixing structure 100 used for the solenoid valve coil.

[0056] like Figure 2 and Figure 4As shown, the main body 12 of the frame includes a cylindrical part 121 and baffle parts 122 that extend outward from the outer periphery of both ends of the cylindrical part 121. The cylindrical part 121 is used to wind electromagnetic coils. The baffle parts 122 are all in contact with the inner peripheral wall of the housing 11. The end cap 13 is disposed on the baffle part 122 at one end. The terminal block 14 is disposed on the baffle part 122 and extends outward from the end cap 13 along the axial direction of the housing 11.

[0057] The fixing structure 100 for the solenoid valve coil of this utility model embodiment divides the frame body 12 into a cylindrical part 121 and baffle parts 122 extending outward along the outer periphery of both ends of the cylindrical part 121. The baffle parts 122 abut against the inner peripheral wall of the housing 11. The wiring terminal 14 is disposed on the baffle part 122 and extends outward along the axial direction of the housing 11 to form an end cap 13. Therefore, the fixing structure 100 has the advantage of good structural integrity.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, the valve core passes through the interior of the cylinder portion 121. The wiring terminal 14 is provided on the baffle portion 122 and extends upward along the axial direction of the housing 11 out of the end cover 13.

[0059] like Figure 1 , Figure 3 and Figure 5 As shown, one of the end cap 13 and the connecting bridge 21 has a locking hole 212, and the other of the end cap 13 and the connecting bridge 21 has a locking protrusion 131, which engages within the locking hole 212. In other words, the end cap 13 has a locking hole 212 and the connecting bridge 21 has a locking protrusion 131; or the end cap 13 has a locking protrusion 131 and the connecting bridge 21 has a locking hole 212.

[0060] The fixing structure 100 of the solenoid valve coil in this embodiment of the invention is defined by the end cap 13 and the connecting bridge 21 through the structure of the latching protrusion 131 and the latching hole 212. Therefore, this fixing structure 100 further improves the ease of overall assembly.

[0061] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, there are multiple protrusions 131 and multiple holes 212, with each protrusion 131 corresponding to a specific hole 212. This structural design further enhances the stability of the structure.

[0062] The solenoid valve assembly module of this embodiment includes a valve body, a valve core, and a fixing structure 100 for the solenoid valve coil of any of the above-mentioned components. The valve core passes through the winding frame assembly 1. Therefore, the solenoid valve assembly module of this embodiment has the advantages of long service life and good applicability.
