Motorcycle, air filter assembly and air intake components

Abstract

This invention relates to a motorcycle, an air filter assembly, and an intake component. The intake component includes an intake housing and a cover. The intake housing has an intake chamber, a mounting groove communicating with the intake chamber, and an exhaust port communicating with the intake chamber. The outer wall of the intake housing has a first connecting portion, and the inner wall of the intake chamber has a second connecting portion. The cover is disposed within the mounting groove and corresponding to the exhaust port. The outer side of the cover has a third connecting portion for connecting with the first connecting portion, and the inner side of the cover has a fourth connecting portion for connecting with the second connecting portion. Because both the outer and inner sides of the cover are connected to the intake housing—specifically, the outer side of the cover connects to the outer wall of the intake housing, and the inner side connects to the inner wall of the intake chamber—and because the cover is positioned corresponding to the exhaust port, external water droplets are prevented from dripping from above into the exhaust port, thus preventing water droplets from entering the air filter body and ensuring good filtration performance of the air filter.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 As shown, in one embodiment, a motorcycle is provided, including a frame 300 and an air filter assembly 10, and the air filter assembly 10 is connected to the frame 300. In this way, the air filter assembly 10 is fixed to the frame 300 by screwing, clamping or plugging, and the air filter assembly 10 is used to filter the air entering the cylinder, thereby providing the cylinder with sufficient clean air for combustion, improving the combustion condition and combustion efficiency. In addition, the air filter assembly 10 can prevent water droplets from entering, ensuring that the air filter assembly 10 can continuously and reliably filter the air, and ensuring that the motorcycle has excellent performance.

[0033] like Figure 2 As shown, the air filter assembly 10 includes an air filter body 200 and an air intake assembly 100, and the air filter body 200 is connected to the air intake cavity 111 of the air intake assembly 100. In this way, the air intake assembly 100 is used to introduce air into the air intake cavity 111 and pass it into the air filter body 200, and the air filter body 200 is used to filter the air and then supply the clean air into the cylinder. In the process of air intake, the air intake assembly 100 can prevent water droplets from entering the exhaust hole of the air intake cavity 111, thereby preventing water droplets from entering the air filter body 200, and ensuring that the filtering effect of the air filter body 200 is excellent.

[0034] It should be noted that the air filter assembly 10 of the above embodiment can also be applied to transportation vehicles such as automobiles. For ease of description, the air filter assembly 10 is applied to a motorcycle as an example, which should not be construed as limiting the application of the air filter assembly 10.

[0035] like Figure 3 As shown, in one embodiment, an air intake assembly 100 is provided, comprising an air intake housing 110 and a cover 120. Figures 3 to 6As shown, the air intake shell 110 is provided with an air intake cavity 111, a mounting groove 112 connected to the air intake cavity 111 and an exhaust hole 113 connected to the air intake cavity 111, and the outer wall of the air intake shell 110 is provided with a first connecting portion 114, and the inner wall of the air intake cavity 111 is provided with a second connecting portion 115; the cover body 120 is arranged in the mounting groove 112 and corresponding to the exhaust hole 113, the outer side of the cover body 120 is provided with a third connecting portion 121 for connecting with the first connecting portion 114, and the inner side of the cover body 120 is provided with a fourth connecting portion 122 for connecting with the second connecting portion 115.

[0036] When the air intake assembly 100 of the above embodiment is assembled, the third connection portion 121 of the cover 120 is connected to the first connection portion 114 of the air intake housing 110, and the fourth connection portion 122 of the cover 120 is connected to the second connection portion 115 of the air intake housing 110, so that the cover 120 is stably and reliably installed in the installation groove 112 at the top of the air intake housing 110. After the air enters the air intake cavity 111, it flows out to the air filter body 200 through the exhaust hole 113, and the air is filtered by the air filter body 200 and the clean air is supplied to the cylinder. At the same time, since the outer side and the inner side of the cover body 120 are connected to the air intake shell 110, the outer side of the cover body 120 is connected to the outer side wall of the air intake shell 110, and the inner side of the cover body 120 is connected to the inner wall of the air intake cavity 111, and the cover body 120 is arranged corresponding to the exhaust hole 113, it is ensured that external water droplets will not drip from the top through the cover body 120 into the exhaust hole 113, thereby preventing water droplets from entering the air filter body 200, thereby ensuring that the air filter body 200 has a good filtering effect.

[0037] The mounting groove 112 may be disposed at an upper position of the air intake housing 110 , and the exhaust hole 113 may be disposed at a lower position of the air intake housing 110 .

[0038] The connection between the first connection portion 114 and the third connection portion 121 may be achieved by means of snap-fitting, plug-fitting, etc.

[0039] In one embodiment, Figure 3 and Figure 5 As shown, the first connecting portion 114 is provided with a buckle 1141. Figure 3 and Figure 6As shown, the third connection part 121 is provided with a slot 1211 for engaging with the buckle 1141. In this way, when the cover body 120 is covered in the installation groove 112, the buckle 1141 and the slot 1211 are only required to engage with each other, so that the outer side of the cover body 120 can be stably and reliably connected to the outer side wall of the air intake housing 110. Compared with the traditional screw connection method, the snap connection method is more convenient for disassembly and assembly, and also avoids the need to open a threaded hole on the air intake housing 110 to cause water leakage.

[0040] The connection between the second connection portion 115 and the fourth connection portion 122 may also be achieved by means of snap-fitting, plug-fitting, etc.

[0041] In one embodiment, Figure 3 and Figure 5 As shown, the second connection portion 115 is provided with a slot 1151. Figure 3 and Figure 6 As shown, the fourth connection portion 122 is provided with an inserting piece 1221 for plugging and matching with the slot 1151. In this way, when the cover body 120 is covered in the installation slot 112, the inner side of the cover body 120 and the inner wall of the air inlet cavity 111 can be stably and reliably connected by simply inserting the inserting piece 1221 into the slot 1151. Compared with the traditional screw connection method, the plug-in method is more convenient for disassembly and assembly, and also avoids the need to open threaded holes on the air inlet housing 110 and the cover body 120 to cause water leakage.

[0042] In one embodiment, Figure 3 and Figure 5 As shown, a first flange 116 is provided on the outer wall of the air intake housing 110, and a first connecting portion 114 is provided on the first flange 116. The first connecting portion 114 is further extended toward the outer side of the air intake housing 110 by using the first flange 116. Figure 3 and Figure 6 As shown, the outer side of the cover body 120 is provided with a second flange 123, and the second flange 123 is provided with a third connection portion 121. In this way, the third connection portion 121 is further extended toward the outer side of the cover body 120 by using the second flange 123, so that the third connection portion 121 is arranged correspondingly to the first connection portion 114, so that the third connection portion 121 can achieve a stable and reliable connection with the first connection portion 114. At the same time, the arrangement of the first flange 116 and the second flange 123 enables the projection of the cover body 120 on the air intake housing 110 to completely cover the contour of the mounting groove 112, so as to better prevent water droplets from entering the exhaust hole 113.

[0043] Among them, the first flange 116 can be a flange or a boss extending toward the outside of the air intake shell 110, and the second flange 123 can be a flange or a boss extending toward the outside of the cover body 120 and then bent toward the air intake shell 110. It only needs to ensure that the first connecting part 114 and the third connecting part 121 can be connected correspondingly.

[0044] In order to stably and reliably assemble and connect the air intake assembly 100, in one embodiment, Figure 3 As shown, the air intake housing 110 is provided with a fifth connection portion 117 for connecting with the vehicle frame 300. Thus, by utilizing the connection between the fifth connection portion 117 and the vehicle frame 300, the air intake housing 110 and the vehicle frame 300 are stably and reliably assembled and connected.

[0045] like Figure 4 and Figure 5 As shown, further, the fifth connecting portion 117 is provided with a connecting column 1171. The frame 300 is provided with a mounting hole (not marked). The air intake assembly 100 also includes a buffer sleeve 130, and the buffer sleeve 130 is arranged in the mounting hole, and the connecting column 1171 is plugged into and matched with the buffer sleeve 130. In this way, the connecting column 1171 is inserted into the buffer sleeve 130, and the plug-in cooperation between the connecting column 1171 and the buffer sleeve 130 is utilized to realize the connection and fixation between the air intake housing 110 and the frame 300. In addition, the buffer sleeve 130 can also buffer and absorb the impact force or vibration force applied by the frame 300 to the air intake housing 110, thereby avoiding or reducing the shaking of the air intake housing 110.

[0046] The buffer sleeve 130 can be made of elastic materials such as rubber and silicone, and can use its own elastic deformation characteristics to buffer and absorb impact or vibration. Both ends of the buffer sleeve 130 can be provided with flange structures, so that the overall shape of the buffer sleeve 130 is an I-shape, ensuring that the buffer sleeve 130 can be stably and reliably installed in the installation hole.

[0047] Of course, in other embodiments, the air intake housing 110 may also be connected to the vehicle frame 300 by means of screw connection or the like, or may be connected by means of a combination of screw connection and plug connection.

[0048] In one embodiment, Figure 3 and Figure 4As shown, the air inlet housing 110 is provided with a drain hole 118 which is offset with the exhaust hole 113 in the horizontal direction and communicated with the air inlet cavity 111, and the air inlet housing 110 and / or the cover body 120 are provided with an air inlet hole 140 which is arranged corresponding to the drain hole 118, and the air inlet hole 140 is communicated with the air inlet cavity 111. In this way, air enters the air inlet cavity 111 through the air inlet hole 140 and finally flows out from the exhaust hole 113. When water droplets are mixed in the air, since the air inlet hole 140 and the drain hole 118 are arranged correspondingly up and down, the water droplets are discharged through the drain hole 118 under the action of gravity, thereby further preventing the water droplets entering from the air inlet hole 140 from entering the exhaust hole 113. Among them, the opening position of the air inlet hole 140 can be flexibly designed or selected according to the actual use situation, as long as the air inlet hole 140 and the drain hole 118 are arranged correspondingly up and down so that the water droplets can fall into the drain hole 118 under the action of gravity. The number of the air inlet holes 140 and the drainage holes 118 can be flexibly designed or adjusted according to actual usage conditions, as long as the corresponding air intake volume is met and the air inlet holes 140 and the drainage holes 118 can be set one-to-one.

[0049] In one embodiment, at least two air inlet holes 140 are provided above the air inlet housing 110, and at least two air inlet holes 140 are arranged at intervals. In this way, by using at least two air inlet holes 140, sufficient air is ensured to enter the air inlet chamber 111 and finally supplied to the cylinder through the exhaust hole 113. At least two drainage holes 118 are provided below the air inlet housing 110, and at least two drainage holes 118 are arranged at intervals. Moreover, the drainage holes 118 are arranged one-to-one with the air inlet holes 140, and an exhaust hole 113 is provided between two adjacent drainage holes 118. In this way, water droplets in the air entering from each air inlet hole 140 can be discharged through the corresponding drainage hole 118, and the dry air separated from the water droplets can enter the air filter body 200 through the exhaust hole 113. At the same time, when there are at least two air inlet holes 140, a partition can be provided between two adjacent air inlet holes 140 to separate them to avoid interference.

[0050] like Figure 3 and Figure 4 As shown, the cover 120 can be installed in the middle of the mounting groove 112, so that air inlet holes 140 are left on the left and right sides of the mounting groove 112, and a drainage hole 118 is correspondingly provided below each air inlet hole 140, and an exhaust hole 113 is provided between the two drainage holes 118. Of course, in other embodiments, the number of the air inlet holes 140 can also be three, four or more, the number of the drainage holes 118 can be correspondingly three, four or more, and the number of the exhaust holes 113 can be correspondingly two, three or more.

[0051] When there are many water drops separated instantly from the drain hole 118, in order to prevent the water drops from overflowing and entering the exhaust hole 113, in one embodiment, Figure 1 and Figure 2 As shown, the air intake assembly 100 also includes a water storage element 150, which is connected to the drain hole 118. In this way, even if a large number of water droplets are separated by the drain hole 118, the water droplets can be stored by using the water storage function of the water storage element 150 to prevent the water droplets from overflowing and entering the exhaust hole 113. Among them, the water storage element 150 can use a cavity-shaped water storage box with a large volume, made of plastic or rubber. The water storage element 150 can also be provided with a discharge pipe to discharge water regularly or in real time, and the diameter of the drain pipe can be set smaller to prevent foreign matter such as dust from entering the water storage element 150 through the drain pipe. The water storage element 150 and the drain hole 118 can be sealed and connected by components such as a sealing ring and a dustproof ring. The water storage element 150 can be integrally formed, or formed separately and then spliced ​​by means of snap connection, etc., as long as it can store water. The water storage element 150 can also be connected to the frame 300 by screw connection, snap connection, etc.

[0052] In order to prevent particles and other debris from entering the air inlet cavity 111 along with the air. Figure 1 and Figure 2 As shown, the air intake assembly 100 further includes a filter element 160, and the filter element 160 is covered in the air intake hole 140. In this way, the filter element 160 can filter larger particles of debris to prevent the debris from clogging the drain hole 118 and the exhaust hole 113. Among them, the filter element 160 can be a filter net, a filter screen, etc., and its filter diameter can be flexibly selected according to actual use needs. The filter element 160 can be connected to the air intake housing 110 by a snap connection, a screw connection, etc., so as to cover the air intake hole 140.

[0053] When the air filter assembly 10 is applied to a motorcycle, the air intake housing 110 can be arranged at the lower left side of the helmet box, and can be crimped up and down with the helmet box, and fixed to the frame 300 by screwing, clamping, plugging, etc. Dustproof foam can also be provided on the crimping surface between the air intake housing 110 and the helmet box.

[0054] It should be noted that "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; it can also be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be manufactured independently and then combined with the "other parts of the component" into a whole.
