Description

Technical Field

[0001] This utility model relates to the field of engine component technology, and in particular to a mounting bracket for a solenoid valve. Background Technology

[0002] As people's demands for automotive comfort continue to increase, NVH (Noise, Vibration, and Harshness) is becoming an important research topic for OEMs and powertrain companies. Car engines vibrate during operation, and engine components need to be securely fastened to prevent failure due to looseness, including the installation of solenoid valves.

[0003] In related technologies, some solenoid valves are installed using an insertion method. The front end of the mounting bracket is designed with a dovetail opening. After inserting the solenoid valve, a tool is used to pry the dovetail groove open to both sides, causing deformation at the bend to fix the solenoid valve in place and prevent it from shaking. However, this installation method requires special tooling to separate the dovetail groove, making installation and disassembly inconvenient. Furthermore, because the mounting bracket is made of metal, the dovetail groove cannot be restored after being pried open (it is prone to breakage), and the mounting bracket can only be used once, resulting in high maintenance and replacement costs.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-6 The present invention describes a mounting bracket 100 for a solenoid valve 200 according to an embodiment of the present invention, and also proposes a vehicle.

[0022] The fixed bracket 100 of this utility model embodiment includes: a snap-fit ​​plate 11, the snap-fit ​​plate 11 being adjustable in width direction, the snap-fit ​​plate 11 having grooves 122 on both sides in width direction, and the top of the snap-fit ​​plate 11 having protrusions 121 adjacent to the grooves 122 on both sides in width direction, the grooves 122 being used to accommodate the mounting plate 210 of the solenoid valve 200, and the protrusions 121 being used to abut against the end of the mounting plate 210.

[0023] Since the size of the snap-fit ​​plate 11 in the width direction is adjustable, the snap-fit ​​plate 11 undergoes a certain plastic deformation during the insertion process, thereby relying on the plastic toughness of the snap-fit ​​plate 11 to clamp the solenoid valve 200.

[0024] Specifically, the side plate of the mounting plate 210 of the solenoid valve 200 fits in the groove 122, and the top of the side plate of the mounting plate 210 abuts against the boss 121, so that the mounting plate 210 can fit on the outside of the snap-fit ​​plate 11. Since the size of the snap-fit ​​plate 11 in the width direction is adjustable, after the snap-fit ​​plate 11 and the mounting plate 210 are installed in place, the snap-fit ​​plate 11 has an outward expansion force, so that the snap-fit ​​plate 11 has a clamping force on the mounting plate 210, thereby preventing the solenoid valve 200 from falling off.

[0025] The solenoid valve 200 can be fixed to the engine body by means of the fixing bracket 100, and the fixing bracket 100 can be installed manually, making disassembly and assembly more convenient.

[0026] Furthermore, the fixed bracket 100 is reusable, avoiding waste in the process of disassembly and maintenance.

[0027] Meanwhile, the cost of plastic raw materials is lower than that of sheet metal. After the overall usage reaches a certain level, the price of the plastic fixing bracket 100 in this utility model embodiment is better than that of the sheet metal fixing bracket 100.

[0028] The fixed bracket 100 of this utility model embodiment can be used to fix and connect with a vacuum solenoid valve. The vacuum solenoid valve is an electronic switch controlled by the engine computer to precisely control the "on" and "off" of the engine's vacuum line (negative pressure), thereby driving various actuators that require a vacuum source.

[0029] For example, vacuum solenoid valves are used in exhaust gas recirculation systems. EGR bypass valves are usually driven by vacuum. The ECU controls the opening and closing of the vacuum solenoid valve in the exhaust gas recirculation system to control the temperature of the exhaust gas introduced into the intake manifold, so as to achieve the purpose of rapid engine warm-up.

[0030] For example, a vacuum solenoid valve is used in a carbon canister purification system, where fuel vapors evaporated from the fuel tank are adsorbed by the carbon canister. When the engine is running, the ECU opens the vacuum solenoid valve of the carbon canister purification system, using the vacuum force of the intake manifold to draw fresh air into the carbon canister and carry the desorbed fuel vapors into the cylinder for combustion, which is both environmentally friendly and fuel-efficient.

[0031] Therefore, since the dimensions of the snap-fit ​​plate 11 are adjustable in the width direction, after the snap-fit ​​plate 11 and the mounting plate 210 are installed in place, the snap-fit ​​plate 11 has an outward expansion force, which makes the snap-fit ​​plate 11 have a clamping force on the mounting plate 210, thereby preventing the solenoid valve 200 from falling off.

[0032] Combination Figures 3-6As shown, the snap-fit ​​plate 11 includes two snap-fit ​​plates 12 and a mating plate 13. The two snap-fit ​​plates 12 are disposed on both sides of the mating plate 13 in the width direction. The snap-fit ​​plates 12 are provided with grooves 122 and protrusions 121. That is, the snap-fit ​​plate 11 is composed of two snap-fit ​​plates 12 and a mating plate 13. The two snap-fit ​​plates 12 are respectively disposed on both sides of the mating plate 13. By providing the mating plate 13, the mating area between the snap-fit ​​plate 11 and the mounting plate 210 can be increased, thereby enabling the snap-fit ​​between the snap-fit ​​plate 11 and the mounting plate 210 to achieve effective snap-fit ​​engagement.

[0033] Furthermore, the two snap-fit ​​boards 12 can be snapped onto the two side plates of the mounting plate 210 respectively, so that a snap-fit ​​structure is formed between the two snap-fit ​​boards 12 and the mounting plate 210.

[0034] Furthermore, such as Figure 3 As shown, the snap-fit ​​board 12 has a guide surface 19 on the side opposite to the mating plate 13. The guide surface 19 can facilitate the snap-fit ​​board 11 to insert the solenoid valve 200.

[0035] like Figures 4-6 As shown, gaps 17 are provided between the two snap-fit ​​plates 12 and the mating plate 13, and the gaps 17 gradually decrease from the end to the bottom of the snap-fit ​​plate 11. That is, the gaps 17 between the snap-fit ​​plates 12 and the mating plate 13 allow the snap-fit ​​plates 12 to deform in the width direction. Thus, when the snap-fit ​​plates 11 and the mounting plate 210 are engaged, the snap-fit ​​plates 12 first move closer to the mating plate 13, i.e., the gaps 17 decrease. Then, after the snap-fit ​​plates 11 and the mounting plate 210 are engaged, the snap-fit ​​plates 12 continuously generate a force away from the mating plate 13, thereby firmly snapping the snap-fit ​​plates 12 into the mounting plate 210.

[0036] Furthermore, the gap 17 gradually decreases in size from the end to the bottom, giving the snap-fit ​​plate 12 a certain degree of flexibility to deform.

[0037] The uppermost dimension of gap 17 is 2.75mm.

[0038] Furthermore, the snap-fit ​​plate 11 is interference-fitted on its outer side in the width direction and on its inner side in the width direction of the mounting plate 210 of the solenoid valve 200. That is, the width of the snap-fit ​​plate 11 is greater than the width of the mounting plate 210. After assembly, there is interference between the snap-fit ​​plate 11 and the mounting plate 210, resulting in significant pressure and friction on the contact surfaces, thus achieving a secure connection. The snap-fit ​​plate 11 tends to return to its original shape, thus tightly clamping itself onto the mounting plate 210.

[0039] The snap-fit ​​plate 11 has a width of 26.5 mm, the mounting plate 210 has an internal width of 26 mm, and the interference between the snap-fit ​​plate 11 and the mounting plate 210 is 0.5 mm.

[0040] In addition, such as Figure 5 As shown, the fixed bracket 100 is provided with a receiving groove 14, and a snap-fit ​​plate 11 is provided inside the receiving groove 14. The mounting plate 210 of the solenoid valve 200 is accommodated in the receiving groove 14. The mounting height of the mounting plate 210 of the solenoid valve 200 is 2mm, therefore the thickness of the snap-fit ​​plate 11 is also 2mm. Consequently, the snap-fit ​​plate 11 is relatively thin in the thickness direction, posing a risk of significant vibration or breakage. Therefore, by providing the receiving groove 14 on the fixed bracket 100, the mounting plate 210 can fit within the receiving groove 14, encasing the solenoid valve 200 from the top and left / right directions, thereby improving the installation stability between the fixed bracket 100 and the mounting plate 210.

[0041] Among them, reference Figure 1 -and Figure 2 As shown, the height of the receiving groove 14 is less than half the height of the mounting plate 210 of the solenoid valve 200. That is, the height of the receiving groove 14 needs to be less than half the height of the mounting plate 210, so as to avoid the receiving groove 14 being too high and affecting the assembly efficiency between the mounting plate 210 and the fixed bracket 100.

[0042] Furthermore, referring to Figure 6 As shown, a guide ramp 18 is provided at the opening of the receiving groove 14. The guide ramp 18 can play a guiding role, thereby further facilitating the installation and cooperation between the fixed bracket 100 and the mounting plate 210.

[0043] Combination Figures 3-6 As shown, the mounting bracket 100 is also provided with a mounting hole 15, and an insert 16 is provided in the mounting hole 15. The mounting hole 15 is used to fix the mounting bracket 100 to the engine body. That is to say, by providing a mounting hole 15 on the mounting bracket 100, a fastener can be passed through the mounting hole 15 and connected to the engine body, thereby fixing the mounting bracket 100 to the engine body.

[0044] Since the mounting bracket 100 is made of plastic, directly screwing in screws or inserting pins into the mounting hole 15 can easily lead to stripped threads or wear on the hole wall. Therefore, providing a hard inner surface inside the mounting hole 15 allows it to withstand all the tightening force and wear, thus protecting the mounting bracket 100.

[0045] Furthermore, the insert 16 is a sleeve-shaped or ring-shaped part that is embedded, pressed into, or installed inside the mounting hole 15. By setting the insert 16, the characteristics of the mounting hole 15 can be strengthened, protected, or changed to achieve a more reliable and durable connection.

[0046] Reference Figures 1-5 As shown, the fixing bracket 100 includes a fixing body 10 and a wire harness fixing plate 20. The wire harness fixing plate 20 is disposed on the fixing body 10, and the fixing body 10 is provided with a snap-fit ​​plate 11. The wire harness fixing plate 20 is provided with a wire harness fixing hole 21. To ensure the integrity between the wire harness plug of the solenoid valve 200 and the solenoid valve 200, the wire harness fixing plate 20 can be disposed on the fixing body 10, and the wire harness fixing hole 21 can be provided on the wire harness fixing plate 20. The wire harness at the rear end of the solenoid valve 200 wire harness plug is fixed by the limiting fixing hole, ensuring that the solenoid valve 200 wire harness plug and the solenoid valve 200 do not vibrate relative to each other, thereby avoiding problems such as loose wire harness connection.

[0047] Among them, reference Figures 1-6 As shown, the fixing bracket 100 also includes a reinforcing plate 22, which is connected between the fixing body 10 and the wire harness fixing plate 20. That is, a reinforcing plate 22 is provided below the wire harness fixing plate 20, and the reinforcing plate 22 is also connected to the fixing body 10. Thus, by providing the reinforcing plate 22, the connection strength between the wire harness fixing plate 20 and the fixing body 10 can be improved.

[0048] Among them, the reinforcing plate 22 can be a triangular structure. In this way, the triangle has stability and can further improve the connection strength between the wire harness fixing plate 20 and the fixing body 10.

[0049] A vehicle according to a second aspect embodiment of the present invention includes an engine system comprising an engine body, a solenoid valve 200, and a mounting bracket 100 for the solenoid valve 200. The mounting bracket 100 is used to fix the solenoid valve 200 to the engine body. That is, the solenoid valve 200 can be fixed to the engine body using the mounting bracket 100. The mounting bracket 100 of this embodiment can be installed manually, making disassembly and assembly more convenient. Furthermore, the mounting bracket 100 is reusable, avoiding waste during disassembly and maintenance. At the same time, the cost of plastic raw materials is lower than that of sheet metal; after the overall usage reaches a certain level, the price of the plastic mounting bracket 100 of this embodiment is superior to that of the sheet metal mounting bracket.
