Description

Multifunctional bracket system

Technical Field

The utility model relates to a mounting system that is arranged in initiative air purification pump of vehicle especially relates to a can integrate multifunctional support system of air pump fixed bolster and sensor support.

Background

Fuel stored in a fuel tank of a vehicle is converted into fuel vapor over time. If fuel vapor is vented into the air, fuel waste can result, and the released unburned fuel can result in air pollution. To overcome these drawbacks, vehicles often include canister purge systems that desorb fuel vapors trapped in the canister, pump the vapors through a line to an intake manifold, and ultimately introduce them into the combustion chamber for combustion.

However, some engines may have a relatively insufficient negative pressure, which is insufficient to transfer fuel vapors trapped in the carbon canister to the intake system of the engine using the engine alone. Therefore, an Active canister Purge system provided with an Active Purge Pump (Active Purge Pump/APP) that can forcibly desorb fuel vapor trapped in a canister to an intake system of an engine with the engine having low manifold vacuum is often used in vehicles and hybrid vehicles having a small displacement engine with insufficient negative pressure.

It will be appreciated that such active purging pumps often require special consideration of the mount system to achieve vibration damping during high speed operation. However, in the known design, in order to achieve the vibration reduction effect, a whole circle of damping rubber pad needs to be mounted on the outer side of the pump body and then fixed by a metal bracket, and the design has the disadvantages of large rubber consumption, serious waste, and complicated structure, and is not favorable for the light-weight design of a bracket system. In addition, the existing bracket body for the purification air pump is mostly formed by injection molding, and the mold is complex, so that the manufacturing cost is high.

In addition, the pipeline pressure sensor support is a part for realizing the fixation of the pressure sensor. The current sensor support is single in functional structure and low in functional integration design degree, so that the overall appearance and reliability of an engine can be influenced in the overall arrangement of the engine, and the design complexity and difficulty of related part structures are increased.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The following description of the present invention may be used in conjunction with any orientation, such as "inner", "outer", "upper", "lower", "circumferential", "axial", etc., unless explicitly stated otherwise, and is for convenience of description only and is not intended to limit the scope of the invention in any way. Furthermore, terms such as "first," "second," and the like are used hereinafter to describe elements of the application. These terms are only used to distinguish one element from another element, and are not intended to limit the nature, sequence, order, or number of such elements.

Referring to fig. 1 and 2, there are shown an assembled perspective view and an exploded perspective view of a fixing bracket for an air pump and the air pump, respectively. The air pump-bracket assembly comprises in particular a fixed bracket 3 connected to the air pump 2 and a damping device, in particular made of an elastic material, arranged between said fixed bracket 3 and said air pump 2. The fixing bracket 3 includes an integrally formed base portion 4, and first and second connecting portions extending laterally and vertically from the base portion 4, respectively, wherein the first connecting portion is fixedly connected to a first receiving portion 5 of the air pump 2 via a fastening means (e.g., a threaded fastener such as a bolt or a screw), and the second connecting portion is axially inserted into a second receiving portion of the air pump 2. Particularly, the fixed support 3 is integrally formed by adopting a stamping technology, and the related whole process is simple and convenient.

Preferably, a vibration damping structure is provided only at a connection region between the fixing bracket 3 and the air pump 2, so that a full-circle damping rubber structure adopted in an existing bracket system is eliminated, thereby reducing the weight of the product as much as possible and ensuring good vibration isolation and vibration damping effects. According to the particular embodiment shown in fig. 2, damping plugs for damping vibrations are provided only between the first connecting portion and the first receiving portion and between the second connecting portion and the second receiving portion.

Referring particularly to fig. 2, the first connection portion of the fixing bracket 3 takes the form of two opposing mounting arms 6. Each mounting arm 6 is preferably screwed into the first receptacle 5 of the air pump 2 by means of a bolt 7. With reference to fig. 2, each mounting arm 6 is provided with an opening 8, in each of said openings 8 intended to receive a first damping plug 9.

As can be seen in fig. 2, this opening 8 takes the form of a C-shaped opening in order to load the first damping plug 9 via the open side of the "C". Of course, other shapes of openings are possible, only to achieve the above-mentioned intended function.

In particular, the first damping plug 9 has two end stop flanges 10, so that the axial displacement of the first damping plug 9 within the opening 8 is limited by said end stop flanges 10. The first damping plug 9 after being installed has a certain pretightening force so as to better play a role in vibration isolation. A metal bush 11 is received in the central through hole of the first damping plug 9 such that the bolt 7 passes through the metal bush 11 and is threadedly engaged in the first receiving portion 5 of the air pump 2.

Advantageously, the metal bushing 11 has a flange portion 12. As can be seen in fig. 2, one of the faces of this flange portion abuts against an end stop flange of said first damping plug 9 and the opposite face abuts against the end face of the bolt head. However, as a preferred alternative, the flange portion 12 can be arranged such that one of its faces abuts against an end stop flange of the first damper plug 9 and the opposite face abuts against the corresponding first receptacle 5 connected to the mounting arm 6, so that on the one hand shear stresses at the first receptacle 5 of the air pump 2 can be avoided and on the other hand supporting the first damper plug 9 by means of the metal bush 11 prevents any undesired deformation of the first damper plug 9.

Referring again to fig. 2, the second connecting portion of the fixing bracket 3 takes the form of a plug 13, while the second receiving portion on the air pump 2 is formed as a socket 14 with a receiving through hole, in which a second damping plug 16 with a central through hole 15 is received, said plug 13 being received in the central through hole 15.

The second damping plug 16 is provided at its two free ends with respective first flanges 17, which first flanges 17 extend beyond the edge of the receiving through hole of the socket 14 to limit the axial displacement of said second damping plug 16 within said receiving through hole. The bolt 13 is provided at its free end with a second flange 18, which second flange 18 extends beyond the edge of the central through hole 15 of the second damping plug 16, so as to limit the axial displacement of the bolt 13 within the central through hole 15 or to prevent the bolt 13 from coming out of the central through hole 15, by means of the second flange 18 and a stop shoulder 19 at the other end of the bolt 13. However, it should be understood that any other possible structure known in the art that is capable of achieving the above-described axial locking or anti-loosening function also falls within the scope of the claimed invention.

Advantageously, at the structural weakness of the fixing bracket 3, as shown in figure 2, a plurality of (preferably three as shown in figure 2) reinforcing ribs 20 are provided at the region of connection of the base 4 with the downwardly bent spigot 13 to further reinforce the structural strength of the overall bracket.

According to an advantageous embodiment of the present invention, as shown in particular in fig. 3, the above-mentioned support system for an air pump may be a multifunctional support system 1 integrating a fixed support 3 for an air pump 2 and a sensor support 22 supporting a sensor 21 for measuring the outlet pressure of the air pump. In the multifunction bracket system 1, the sensor bracket 22 carrying the sensor 21 is fixedly held at the first connection portion of the fixing bracket 3, in particular at one of the mounting arms 6.

Referring to fig. 4, the sensor bracket 22 includes a mounting flange 23, and the mounting flange 23 is riveted with the left mounting arm 6 via bolts 27. The sensor holder 22 further comprises a positioning pin 24 having a certain elastic deformability, and the positioning pin 24 has a stop flange 25 at its free end, so that, once the positioning pin 24 is inserted into a pin hole 26 in the corresponding mounting arm 6 with a certain elastic deformation, the positioning pin 24 is prevented from coming out of the pin hole 26 by the stop flange 25.

It should be noted that the above-described embodiments should be regarded as merely exemplary, and the present invention is not limited to these embodiments. Upon consideration of the present specification, those skilled in the art can make various changes and modifications without departing from the scope or spirit of the present invention.
