DETAILED DESCRIPTION
[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0027] Reference below Figure 1-Figure 3 The air filter bracket of the embodiment of the utility model saves more space at the installation point than setting a shock-absorbing pad, and has a better shock-absorbing effect while solving the previous single method of achieving the effect of vibration isolation by adding a vibration isolation rubber pad at the installation point.
[0028] like Figure 1-3As shown, the air filter bracket according to the embodiment of the utility model includes: a bracket body 1, the bracket body 1 includes a main body 11 and a mounting seat 12, one end of the main body 11 is used to connect to the air filter body 2 and the other end is connected to the mounting seat 12, the mounting seat 12 is used to connect to the mounting piece, and the main body 11 is constructed as a corrugated structure.
[0029] Among them, the bracket body 1 is used to connect to the air filter body 2, and the air filter body 2 is fixed to the vehicle body or powertrain through the bracket body 1. Since the engine is a very precise machine, even very small impurities can damage the engine. Therefore, before the air enters the cylinder, it must first be filtered by the air filter before entering the cylinder. The air filter is a device that is mainly responsible for removing particulate impurities in the air.
[0030] When the air filter is installed on the vehicle body or powertrain, the air filter body 2 can be installed and supported on the vehicle body or powertrain through the bracket body 1. For example, the bracket body 1 is provided with a mounting seat 12, and the mounting seat 12 is connected to the vehicle body or powertrain through a mounting member. The main body 11 of the bracket body 1 and the mounting seat 12 can be set as one body, or the main body 11 and the mounting seat 12 can be connected to each other to form the bracket body 1, and the corrugated structure of the main body 11 has a good shock-absorbing effect. For example, the main body 11 of the bracket body 1 can be set as a shock-absorbing material such as rubber material, that is, at this time, the bracket body 1 has both a supporting function and a shock-absorbing effect, and there is no need to set a shock-absorbing pad separately. The shock-absorbing effect can be achieved through the structural setting of the bracket body 1 itself, and the corrugated structure can absorb a large amount of vibration energy.
[0031] Therefore, the air filter bracket of the embodiment of the utility model saves more space at the installation point than setting a shock-absorbing pad, and has a better shock-absorbing effect while solving the previous single method of achieving the effect of vibration isolation by only adding a vibration isolation rubber pad at the installation point.
[0032] In some embodiments, a shock absorbing chamber 13 is provided in the corrugated structure. Specifically, the shock absorbing chamber 13 can be provided in the middle of the main body 11 during design, and the provision of the shock absorbing chamber 13 does not affect the supporting performance of the entire bracket body 1. The provision of the shock absorbing chamber 13 can better absorb vibration energy, and combined with the corrugated structure, the air filter has a better shock absorbing effect.
[0033] In some embodiments, the main body 11 includes a first corrugated plate 111 and a second corrugated plate 112 relative to each other, one end of the first corrugated plate 111 and one end of the second corrugated plate 112 are spaced apart and connected to the mounting seat 12, and the other end of the first corrugated plate 111 and the other end of the second corrugated plate 112 are spaced apart and connected to the air filter body 2, and a shock absorbing chamber 13 is formed between the air filter body 2, the first corrugated plate 111, the second corrugated plate 112 and the mounting seat 12.
[0034] In practice, it can be combined Figure 1 and Figure 2 As shown, the first corrugated plate 111 and the second corrugated plate 112 are arranged opposite to each other and form the main body 11. Furthermore, the angle between the outer side surface of the first corrugated plate 111 and the air filter body 2 is an acute angle. At the same time, the angle between the outer side surface of the second corrugated plate 112 and the air filter body 2 is also an acute angle, which improves the stability of the support of the bracket body 1. At the same time, the first corrugated plate 111 and the second corrugated plate 112 can be arranged in parallel to balance the force on the first corrugated plate 111 and the second corrugated plate 112. That is, after the bracket body 1 is connected to the air filter body 2, the bracket body 1 has better supporting performance and shock absorption effect on the air filter body 2.
[0035] In some embodiments, the air filter bracket further includes a reinforcing connection portion 3 , which is connected between ends of the first corrugated plate 111 and the second corrugated plate 112 , and is used to be connected to the air filter body 2 .
[0036] In practice, the reinforcing connection portion 3 is constructed as a rectangular parallelepiped, and the longer side of the rectangular parallelepiped is connected to the air filter body 2, and the two shorter sides of the rectangular parallelepiped are located between the first corrugated plate 111 and the second corrugated plate 112 and are respectively connected to the ends of the first corrugated plate 111 and the second corrugated plate 112. At this time, the first corrugated plate 111 and the second corrugated plate 112 are also connected to the air filter body 2, that is, one end of the bracket body 1 can be reinforced by the reinforcing connection portion 3, and the other end can be reinforced by the mounting seat 12, so as to meet the premise that the bracket body 1 has good supporting performance. The corrugated structure and the shock absorbing chamber 13 are appropriately arranged, so that when the bracket body 1 is connected to the vehicle body or the engine assembly and is affected by external vibration, the connection strength between the bracket body 1 and the air filter body 2 is better, so that the reinforced connection part 3, the first corrugated plate 111, the second corrugated plate 112 and the mounting seat 12 are jointly supported on the air filter body 2, and at this time, the shock absorbing chamber 13 is formed by the reinforced connection part 3, the first corrugated plate 111, the second corrugated plate 112 and the mounting seat 12, so as to achieve the shock absorption and energy absorption effect while ensuring better supporting performance.
[0037] In some embodiments, the first corrugated plate 111 includes a plurality of continuous first step portions 1111 and the second corrugated plate 112 includes a plurality of continuous second step portions 1121, the first step portion 1111 includes a connected first connecting surface 1112 and a second connecting surface 1113, the second step portion 1121 includes a connected third connecting surface 1122 and a fourth connecting surface 1123, wherein the third connecting surface 1122 is parallel to the first connecting surface 1112, and the fourth connecting surface 1123 is parallel to the second connecting surface 1113.
[0038] Specifically, by making the first connection surface 1112 of the first step portion 1111 and the third connection surface 1122 of the second step portion 1121 parallel, and the second connection surface 1113 of the first step portion 1111 and the fourth connection surface 1123 of the second step portion 1121 parallel, when the bracket body 1 connects the air filter body 2 to the vehicle body or the engine assembly and is subjected to vibration, the vibration force firstly moves along the Figure 2 The mounting seat 12 faces upward and continues to face the second corrugated plate 112, so that the force is first transmitted along the fourth connecting surface 1123 of the second step portion 1121, and continues to be transmitted toward the third connecting surface 1122. Similarly, the vibration force continues to be transmitted upward along the mounting seat 12 to the first connecting surface 1112 of the first corrugated plate 111, and continues to be transmitted to the second connecting surface 1113 along the second connecting surface 1113; and the first connecting surface 1112 and the third connecting surface 1122 are set to be parallel, and the second connecting surface 1113 and the fourth connecting surface 1123 are set to be parallel, then the vibration force can be uniformly transmitted in different directions toward the second corrugated plate 112, and at the same time, the vibration force can be uniformly transmitted in different directions toward the first corrugated plate 111. At this time, the force is more uniform, preventing the force from being concentrated at a certain position of the main body 11 and causing deformation of the main body 11.
[0039] In some embodiments, the main body 11 is constructed as a bellows, one end of the bellows is connected to the air filter body 2 and the other end is connected to the mounting seat 12 , and the hollow cavity of the bellows forms a shock absorbing cavity 13 .
[0040] In practice, when the main body 11 is constructed as a bellows, one end of the mounting seat 12 can be set as a structure that cooperates with the bellows to facilitate the installation and connection of the bellows. The bellows has good elasticity and flexibility and can withstand higher pressure. The bellows has strong impact resistance and good shock absorption effect.
[0041] During specific design, the number of the first step portions 1111 of the first corrugated plate 111 and the second step portions 1121 of the second corrugated plate 112 can be increased according to actual vibration isolation requirements, or the length of the corrugated tube can be increased. At the same time, the thickness of the first corrugated plate 111 and the second corrugated plate 112 or the wall thickness of the corrugated tube can also be increased according to actual vibration isolation requirements.
[0042] In some embodiments, the mounting base 12 includes a first connecting portion 121 and a second connecting portion 122 connected to each other. The first connecting portion 121 and the second connecting portion 122 have an included angle. The first connecting portion 121 is connected to one end of the main body 11, and the second connecting portion 122 is used to connect to the mounting piece.
[0043] In practice, the mounting seat 12 is designed to be connected to the first connecting portion 121 and the second connecting portion 122, which facilitates the connection between the first connecting portion 121 and the main body 11, and facilitates the connection between the second connecting portion 122 and the vehicle body or the powertrain, and the angle between the first connecting portion 121 and the second connecting portion 122 can be set to an obtuse angle, so as to better disperse the vibration force when the vibration force is transmitted along the mounting seat 12.
[0044] In addition, when the main body 11 is designed as the first corrugated plate 111 and the second corrugated plate 112, the first connecting portion 121 of the mounting seat 12 can be configured as Figure 2 In the structure shown, the interior of the mounting seat 12 is a solid structure, and a supporting slope 124 is provided at one end close to the main body 11. The supporting slope 124 can facilitate the connection between the mounting seat 12 and the first corrugated plate 111 and the second corrugated plate 112, and can also improve the stability of the mounting seat 12. When the main body 11 is designed as a bellows, the end of the first connecting portion 121 close to the main body 11 is constructed as a cavity structure, and one end of the bellows is connected to the cavity structure of the mounting seat 12, which can facilitate the connection between the bellows and the mounting seat 12.
[0045] In some embodiments, the second connection portion 122 is provided with a mounting hole 123 , and the second connection portion 122 is connected to the mounting member via a connecting member penetrating through the mounting hole 123 .
[0046] Specifically, by providing a mounting hole 123 on the second connecting portion 122, the connecting member passes through the mounting hole 123 and is connected to the vehicle body or the powertrain, so that the air filter can be detachably connected to the vehicle body or the powertrain, so that the air filter can be installed in a suitable position according to actual conditions. In actual design, the thickness of the mounting seat 12 can be appropriately increased to improve the connection strength between the mounting seat 12 and the vehicle body or the powertrain.
[0047] The utility model also discloses an air filter, comprising an air filter body 2 and the above-mentioned air filter bracket. There are multiple bracket bodies 1, and the multiple bracket bodies 1 are spaced apart and connected to the air filter body 2.
[0048] Among them, by arranging multiple bracket bodies 1 around the air filter body 2, it can not only achieve better supporting performance for the air filter body 2, but also have a better shockproof effect on the basis of ensuring good support. The shockproof performance of the bracket body 1 is achieved by combining a corrugated tube or a first corrugated plate 111 with a second corrugated plate 112.
[0049] The utility model embodiment also discloses a vehicle, including the above-mentioned air filter. Compared with setting a shock-absorbing pad, the air filter saves more space at the installation point, and has a better shock-absorbing effect. At the same time, it solves the previous single method of vibration isolation that can only achieve the effect by adding a vibration isolation rubber pad at the installation point, thereby improving the shock-absorbing performance of the air filter and improving the user experience. At the same time, it can also save space for setting a shock-absorbing pad, and there is no need to set a shock-absorbing pad separately, which saves cost and is convenient to implement.
