Description

Technical Field

[0001] This utility model relates to the field of natural gas engine fuel system technology, specifically to a vibration damping module bracket. Background Technology

[0002] During the development of the Z15N FE gas engine, the applicant discovered that the vibration at the ignition control module exceeded its tolerance. In the vibration acceleration test of the ignition control module, all the samples failed the verification, indicating that the ignition control module has a high risk of failure if it operates in such a vibration environment for a long time. Therefore, it is necessary to design a vibration reduction structure for the ignition control module. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a vibration damping module bracket that transforms the rigid connections between the fuel control valve bracket, support bracket, and bolts into elastic connections, effectively reducing vibration transmission and meeting the vibration limits of the ignition control module.

[0004] To solve the above-mentioned technical problems, this utility model provides a vibration damping module bracket, comprising:

[0005] A fuel control valve bracket for mounting on the cylinder block of an engine, the fuel control valve bracket having a plurality of first connection holes;

[0006] A support bracket is provided for the installation of the ignition control module. The support bracket includes a connecting plate with a second connecting hole corresponding to a first connecting hole. The connecting plate is parallel to the fuel control valve bracket. The connecting plate is installed on the fuel control valve bracket by bolts passing through the first and second connecting holes. The bolts are threaded to the first connecting hole and do not contact the connecting plate. Elastic damping blocks are provided between the connecting plate and the fuel control valve bracket, as well as between the connecting plate and the bolts.

[0007] In some embodiments, the vibration damping block includes a first vibration damping block and a second vibration damping block, both of which have through holes, and the bolt passes through the first vibration damping block and the second vibration damping block.

[0008] In some embodiments, one end of the second damping block extends into the through hole of the first damping block and is interference-fitted with the first damping block.

[0009] In some embodiments, the second damping block is in close contact with the inner wall of the second connecting hole, and the second damping block and the second connecting hole are arranged coaxially.

[0010] In some embodiments, the support bracket includes a mounting plate that is perpendicular to the connecting plate and fixedly connected to the connecting plate.

[0011] In some embodiments, the second connection hole is arranged on both sides of the mounting plate.

[0012] In some embodiments, the second connection holes located on both sides of the mounting plate are staggered.

[0013] In some embodiments, the mounting plate and the connecting plate are integrally formed.

[0014] In some embodiments, a stiffening plate is provided between the mounting plate and the connecting plate, and the stiffening plate is perpendicular to the mounting plate and the connecting plate.

[0015] In some embodiments, a limiting groove is provided on the fuel control valve bracket, the limiting groove is coaxially arranged with the first connecting hole, and the first damping block is located in the limiting groove.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model forms a hamburger-style vibration damping structure by setting vibration damping blocks on both sides of the connecting plate, which consists of bolt-vibration damping block-support bracket-vibration damping block-fuel control valve bracket. The vibration on the fuel control valve bracket can only be transmitted through the vibration damping blocks, which greatly reduces the vibration of the ignition control module installed on the support bracket.

[0018] 2. The bolts of this utility model are inserted into the first damping block and the second damping block, which facilitates the installation of the first damping block and the second damping block.

[0019] 3. One end of the second damping block of this utility model extends into the through hole of the first damping block and is interference-fitted with the first damping block, which can reduce the risk of resonance between the two damping blocks. Furthermore, the first and second damping blocks can be pre-installed on the support bracket before bolt installation, which helps to reduce assembly difficulty.

[0020] 4. The second damping block of this utility model is in close contact with the inner wall of the second connecting hole, and the second damping block and the second connecting hole are arranged coaxially, which helps to improve the coaxiality of the bolt, the first damping block and the second damping block, and avoids the bolt being subjected to shear force during vibration.

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0028] like Figures 1 to 3 As shown, this utility model provides a vibration damping module bracket, including a fuel control valve bracket 1 and a support bracket 2. The fuel control valve bracket 1 is installed on the engine block. When the engine is running, the vibration on it will be transmitted to the support bracket 2 through the fuel control valve bracket 1, and then to the ignition control module of the support bracket 2.

[0029] like Figure 4 As shown, the fuel control valve bracket 1 has multiple first connection holes 11. The support bracket 2 includes a connecting plate and a mounting plate arranged perpendicularly to each other. The connecting plate and the mounting plate are an integral structure. The mounting plate is connected to the fuel control valve bracket 1 through the connecting plate. The mounting plate is used to install the ignition control module. The connecting plate has multiple second connection holes 21. The multiple first connection holes 11 and the multiple second connection holes 21 are arranged in a one-to-one correspondence. The connecting plate is installed on the fuel control valve bracket 1 by bolts 5 passing through the first connection holes 11 and the second connection holes 21. The bolts 5 are threaded to the first connection holes 11. The bolts 5 do not contact the connecting plate. Elastic damping blocks are provided between the connecting plate and the fuel control valve bracket 1, as well as between the connecting plate and the bolts 5.

[0030] Understandably, since the connecting plate and the fuel control valve bracket 1 are elastically connected by damping blocks, and the bolt 5 does not contact the connecting plate, the vibration is transmitted only through the damping blocks. Therefore, after the engine vibration is transmitted to the fuel control valve bracket 1, it can only be transmitted to the support bracket 2 through the two damping blocks, which greatly reduces the vibration of the ignition control module installed on the support bracket 2.

[0031] In some embodiments, such as Figure 5As shown, the vibration damping block includes a first vibration damping block 3 and a second vibration damping block 4. Both the first vibration damping block 3 and the second vibration damping block 4 have through holes. Bolts 5 are inserted through the first vibration damping block 3 and the second vibration damping block 4. Therefore, before tightening the bolts 5, the first vibration damping block 3 and the second vibration damping block 4 can be hung on the bolts 5, and then the bolts 5 can be tightened, which facilitates the installation of the first vibration damping block 3 and the second vibration damping block 4.

[0032] In some embodiments, such as Figure 5 As shown, the second damping block 4 includes an integrated isolation part 41, a first insertion part 42, and a second insertion part 43. The isolation part 41 is located between the nut of the bolt 5 and the connecting plate. The first insertion part 42 is located in the second connecting hole 21. The second insertion part 43 is inserted into the first damping block 3 and has an interference fit with the first damping block 3.

[0033] It is understandable that if elastic damping blocks are only installed between the connecting plate and the fuel control valve bracket 1, and between the connecting plate and the bolt 5, the damping blocks may experience frequency changes under vibration. When these changes approach the natural frequencies of other structures, resonance may occur, thus failing to achieve the purpose of vibration damping. This invention reduces the risk of resonance by using an interference fit between the first damping block 3 and the second damping block 4. Furthermore, before screwing in the bolt 5, the first damping block 3 can be placed on one side of the second connecting hole 21, and the second damping block 4 can be inserted from the other side of the second connecting hole 21 and connected to the first damping block 3. In this way, the first damping block 3 and the second damping block 4 are pre-installed on the support bracket 2, which helps to reduce assembly difficulty.

[0034] In some embodiments, such as Figure 5 As shown, the second damping block 4 is in close contact with the inner wall of the second connecting hole 21, that is, the first insertion part 42 is in close contact with the inner wall of the second connecting hole 21, and the second damping block 4 and the second connecting hole 21 are arranged coaxially.

[0035] Understandably, if the first damping block 3 and the second damping block 4 are hung on the bolt 5 and then the bolt 5 is tightened, the coaxiality of the bolt 5, the first damping block 3, and the second damping block 4 will decrease. Under the action of vibration, the bolt 5 will be subjected to periodic shear force, reducing the reliability of the structure. In this invention, the second damping block 4 is coaxially arranged with the second connecting hole 21 and can be pre-installed on the second connecting hole 21, thus ensuring the coaxiality of the bolt 5, the first damping block 3, and the second damping block 4.

[0036] like Figure 4 As shown, a limiting groove is provided on the fuel control valve bracket 1. The diameter of the limiting groove is larger than the diameter of the first connecting hole 11. The limiting groove and the first connecting hole 11 are arranged coaxially. The first damping block 3 is located in the limiting groove.

[0037] Understandably, after the second damping block 4 and the first damping block 3 are pre-installed on the support bracket 2, the support bracket 2 needs to be installed on the fuel control valve bracket 1. By setting a limiting groove, the first damping block 3 can cooperate with the limiting groove for positioning, so that the bolt 5 can be directly aligned with the first connecting hole 11, which is convenient for installation.

[0038] like Figure 1 As shown, the second connecting holes 21 are arranged on both sides of the mounting plate, and the second connecting holes 21 on both sides of the mounting plate are staggered.

[0039] like Figure 1 As shown, a stiffening plate is provided between the mounting plate and the connecting plate. The stiffening plate is perpendicular to the mounting plate and the connecting plate, which improves the reliability of the support bracket 2.

[0040] This invention creates a hamburger-style vibration damping structure by adding vibration damping blocks at the connection holes of the support bracket 2 and the fuel control valve bracket 1, forming a structure of bolt 5 - second vibration damping block 4 - support bracket 2 - first vibration damping block 3 - fuel control valve bracket 1. After the implementation of this vibration damping module bracket, the vibration of the ignition control module is reduced by 60%, meeting the vibration limits of the ignition control module.

[0041] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
