Moreover, the expansion cavity in the expansion cavity 40 can buffer the intake air, thereby Effectively reduce the noise generated by the intake of the engine 20.
因此，根据本申请实施例的全地形车1具有发动机进气噪音小、工作稳定性高等优点。Therefore, the all-terrain vehicle 1 according to the embodiment of the present application has the advantages of low engine intake noise and high working stability.
在本申请的一些具体实施例中，如图1所示，发动机20具有节气门21，空气滤清器30具有出口31，膨胀腔体40连接在出口31与节气门21之间，从空气滤清器30的出口31流出的空气，经膨胀腔体40膨胀后，由节气门21进入发动机20的燃烧室。In some specific embodiments of the present application, as shown in FIG. 1, the engine 20 has a throttle 21, the air cleaner 30 has an outlet 31, and an expansion chamber 40 is connected between the outlet 31 and the throttle 21 to filter the air The air flowing out of the outlet 31 of the cleaner 30 is expanded by the expansion cavity 40 and then enters the combustion chamber of the engine 20 through the throttle 21.
其中，为了便于空气滤清器30、膨胀腔体40和发动机20在车架10上的合理布置，膨胀腔体40与节气门21通过节气门连接管41相连，膨胀腔体40与 出口31通过膨胀腔连接管42相连，所述膨胀腔的横截面积分别大于节气门连接管41的横截面积和膨胀腔连接管42的横截面积，从而保证膨胀腔体40对气流的缓冲和稳定效果。Among them, in order to facilitate the rational arrangement of the air cleaner 30, the expansion cavity 40 and the engine 20 on the frame 10, the expansion cavity 40 and the throttle 21 are connected by a throttle connecting pipe 41, and the expansion cavity 40 and the outlet 31 pass through The expansion cavity connecting pipe 42 is connected, and the cross-sectional area of the expansion cavity is larger than the cross-sectional area of the throttle connecting pipe 41 and the cross-sectional area of the expansion cavity connecting pipe 42 respectively, thereby ensuring the cushioning and stabilizing effect of the expansion cavity 40 on the airflow .
在本申请的一些具体实施例中，如图1-图3所示，车架10具有驾驶室11，发动机20、空气滤清器30和膨胀腔体40均设于驾驶室11的后方，形成后驱形式。In some specific embodiments of the present application, as shown in FIGS. 1 to 3, the frame 10 has a cab 11, and the engine 20, the air cleaner 30 and the expansion cavity 40 are all arranged behind the cab 11 to form Rear drive form.
进一步地，结合全地形车1的后驱形式，合理利用空间，优化整车布置，膨胀腔体40位于发动机20的前方，且膨胀腔体40在左右方向上位于空气滤清器30的一侧。Further, in combination with the rear-wheel drive form of the all-terrain vehicle 1, rational use of space and optimization of the vehicle layout, the expansion cavity 40 is located in front of the engine 20, and the expansion cavity 40 is located on one side of the air cleaner 30 in the left-right direction .
在本申请的一些具体示例中，如图1所示，发动机20具有排气口，所述排气口连接有排气管22，排气管22连接有消音器23，利用消音器23对发动机20的排气进行降噪，从而降低发动机20的排气噪音。In some specific examples of the present application, as shown in FIG. 1, the engine 20 has an exhaust port, the exhaust port is connected with an exhaust pipe 22, the exhaust pipe 22 is connected with a muffler 23, the use of the muffler 23 to the engine The exhaust gas of 20 reduces noise, thereby reducing the exhaust noise of the engine 20.
进一步地，所述排气口朝向后方设置，消音器23位于发动机20的后方且安装于车架10，一方面能够降低驾驶室11后下方的温度，使发动机20的热量从前方排向后方，提高驾驶室11的舒适性，且可以避免驾驶室11后下方的零部件长时间受到高温的烘烤而影响零部件的使用寿命；另一方面，排气口朝向驾驶室11的后方设置，发动机20的排气通过排气管22经消音器23排向后方，这样能够降低发动机20的排气阻力，提升发动机20的功率。Further, the exhaust port is arranged toward the rear, and the muffler 23 is located behind the engine 20 and is installed on the frame 10. On the one hand, it can reduce the temperature of the lower rear of the cab 11, so that the heat of the engine 20 is discharged from the front to the rear. Improve the comfort of the cab 11, and can prevent the parts under the cab 11 from being baked at high temperature for a long time, which will affect the service life of the parts; on the other hand, the exhaust port is set toward the rear of the cab 11, and the engine The exhaust gas of 20 passes through the exhaust pipe 22 and is discharged to the rear through the muffler 23, which can reduce the exhaust resistance of the engine 20 and increase the power of the engine 20.
在本申请的一些具体示例中，如图2和图3所示，为了提高全地形车1的装载能力，全地形车1还包括货箱50，货箱50安装于车架10，发动机20、空气滤清器30和膨胀腔体40均设于货箱50的下方。In some specific examples of the present application, as shown in FIGS. 2 and 3, in order to improve the loading capacity of the all-terrain vehicle 1, the all-terrain vehicle 1 further includes a cargo box 50, which is mounted on the frame 10, the engine 20, The air cleaner 30 and the expansion cavity 40 are both arranged below the cargo box 50.
在本申请的一些具体示例中，如图3所示，空气滤清器30的进口连接有进气延长管300，且进气延长管300具有空滤器进气口321，进气延长管300的至少一部分向上延伸以使空滤器进气口321高于节气门21。由此能够避免全地形车1在行驶途中飞溅的水从空滤器进气口321进入空气滤清器30和发动机20，提高全地形车1的涉水通过性，从而保障行驶稳定和发动机的使用寿命。In some specific examples of the present application, as shown in FIG. 3, the inlet of the air cleaner 30 is connected with an intake extension pipe 300, and the intake extension pipe 300 has an air filter intake port 321, and the intake extension pipe 300 At least a portion extends upward so that the air filter inlet 321 is higher than the throttle valve 21. This can prevent the water splashed by the all-terrain vehicle 1 from entering the air filter 30 and the engine 20 from the air filter inlet 321 during driving, and improve the wading ability of the all-terrain vehicle 1 to ensure driving stability and engine use life.
进一步地，如图3所示，驾驶室11内设有座椅，空滤器进气口321的高度 对应所述座椅的靠背120的上部区域，即通过进气延长管300的延伸，使空滤器进气口321的高度与乘坐人员的肩部大体持平，从而使空滤器进气口321位于合理高度，避免发动机20涉水。例如，进气延长管300从货箱50的前方向上延伸以使空滤器进气口321高于货箱50，进气延长管300的一部分可以埋设在驾驶室11的后壁内，空滤器进气口321朝向后方设置。这样不仅可以提升空滤器进气口321的高度，便于进气延长管300的布置，而且利于空滤器进气口321的进气，避免货箱50的设置影响进气量。Further, as shown in FIG. 3, a seat is provided in the cab 11, and the height of the air filter inlet 321 corresponds to the upper area of the seat back 120, that is, through the extension of the air inlet extension pipe 300, the air The height of the filter air inlet 321 is substantially equal to the shoulders of the occupants, so that the air filter air inlet 321 is located at a reasonable height and the engine 20 is prevented from wading through water. For example, the intake extension pipe 300 extends upward from the front of the cargo box 50 so that the air filter inlet 321 is higher than the cargo box 50. A part of the intake extension pipe 300 may be buried in the rear wall of the cab 11, and the air filter enters The air port 321 is arranged toward the rear. This not only increases the height of the air filter inlet 321, facilitates the arrangement of the air intake extension pipe 300, but also facilitates the air intake of the air filter inlet 321, and prevents the installation of the cargo box 50 from affecting the air intake.
在本申请的一些具体示例中，如图3所示，全地形车1还包括前置过滤件500，前置过滤件500设于进气延长管300，例如，前置过滤件500设于进气延长管300的空滤器进气口321处。由空滤器进气口321进入进气延长管300的空气首先经过前置过滤件500过滤，从而为空气滤清器30和发动机20提供更加洁净的空气，延长空气滤清器30和发动机20的使用寿命。In some specific examples of the present application, as shown in FIG. 3, the all-terrain vehicle 1 further includes a pre-filter 500, which is arranged in the intake extension pipe 300, for example, the pre-filter 500 is arranged in the inlet At the air filter inlet 321 of the air extension pipe 300. The air entering the intake extension pipe 300 from the air filter inlet 321 is first filtered by the pre-filter 500, thereby providing cleaner air for the air filter 30 and the engine 20, and extending the air filter 30 and the engine 20 Service life.
在本申请的一些具体示例中，如图3所示，进气延长管300包括空滤器连接管310和空滤器进气管320。In some specific examples of the present application, as shown in FIG. 3, the intake extension pipe 300 includes an air filter connection pipe 310 and an air filter intake pipe 320.
空滤器连接管310的一端与空气滤清器30相连，空滤器连接管310的另一端形成第一对接端311，第一对接端311朝向上方。空滤器进气管320的一端形成空滤器进气口321且另一端形成第二对接端322，第二对接端322朝向下方且与第一对接端311对接，例如，第一对接端311和第二对接端322通过抱箍330对接。One end of the air filter connecting pipe 310 is connected to the air filter 30, and the other end of the air filter connecting pipe 310 forms a first docking end 311, and the first docking end 311 faces upward. One end of the air filter intake pipe 320 forms an air filter intake port 321 and the other end forms a second docking end 322. The second docking end 322 faces downward and is docked with the first docking end 311, for example, the first docking end 311 and the second docking end 311. The docking end 322 is docked by the hoop 330.
由此可以便于进气延长管300在整车上的装配。具体地，由于进气延长管300的延伸路径需要多次折弯，如将进气延长管300设置成一体件则无法顺利到位安装，且受到整车结构的限制，在水平方向上受到干涉的部件较多，即在水平方向上的自由空间较小，在此种情况下，将进气延长管300设置成空滤器连接管310和空滤器进气管320，且空滤器连接管310的第一对接端311朝上，空滤器进气管320的第二对接端322朝向，这样可以使空滤器连接管310和空滤器进气管320在上下方向上进行装配，例如，先将空滤器连接管310连接至空气滤清器30，再将空滤器进气管320由上至下与空滤器连接管310对接，从 而方便进气延长管300的装配。This can facilitate the assembly of the intake extension pipe 300 on the entire vehicle. Specifically, since the extension path of the intake extension pipe 300 needs to be bent multiple times, if the intake extension pipe 300 is formed as a single piece, it cannot be installed smoothly in place, and is restricted by the structure of the vehicle, which interferes in the horizontal direction. There are many components, that is, the free space in the horizontal direction is small. In this case, the intake extension pipe 300 is set as the air filter connecting pipe 310 and the air filter intake pipe 320, and the first part of the air filter connecting pipe 310 The docking end 311 faces upwards, and the second docking end 322 of the air filter inlet pipe 320 faces, so that the air filter connecting pipe 310 and the air filter inlet pipe 320 can be assembled up and down, for example, the air filter connecting pipe 310 is connected first To the air filter 30, the air filter intake pipe 320 is connected to the air filter connecting pipe 310 from top to bottom, so as to facilitate the assembly of the intake extension pipe 300.
