[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 7 An air filter overflow device 100 according to an embodiment of the present invention is described. The air filter overflow device 100 can be applied to a vehicle.

[0032] In the prior art, the vehicle's air filter structure is arranged on the left and right sides of the engine or directly above it, while the overflow structure in the cooling system needs to be arranged at the high point of the cooling system. The air filter structure and the overflow structure are arranged separately, which not only increases the difficulty of arranging the engine compartment, but also makes the engine compartment structure less compact, the engine is more bloated, and occupies a larger space.

[0033] Combination Figure 1-Figure 7 As shown, the air filter overflow device 100 according to the utility model can mainly include: an air filter housing 10 and an overflow housing 20. Among them, the air filter housing 10 defines a receiving space 103, and an air filter 104 is arranged in the receiving space 103. After the gas enters the receiving space 103 from the external space, it is filtered by the air filter 104, and relatively clean air flows out of the receiving space 103 and flows to the engine, so that the engine intake can obtain relatively clean air, which can improve the working performance and service life of the engine.

[0034] The overflow housing 20 includes an overflow upper shell 201 and an overflow lower shell 202. The overflow lower shell 202 is arranged in the accommodating space 103 and is an integrally formed structure with the air filter housing 10. The overflow upper shell 201 is located above the overflow lower shell 202 and is connected to the overflow lower shell 202. The overflow upper shell 201 and the overflow lower shell 202 jointly define a storage space 203.

[0035] Specifically, by arranging the overflow lower shell 202 in the accommodating space 103 and integrally forming the overflow lower shell 202 with the air filter housing 10, the structure that serves as the air filter and the structure that serves as the overflow tank can be integrated to prevent the air filter structure and the overflow structure from being arranged separately. When applying it to the engine, the arrangement of the air filter overflow device 100 in the engine can be simplified.

[0036] It should be noted that the air filter structure can filter the air entering the engine from the outside and prevent foreign matter in the air from entering the engine.

[0037] The overflow structure is used to store antifreeze. When the engine temperature rises, the antifreeze will expand and exceed the capacity of the water tank. At this time, the antifreeze will enter the overflow structure. As the antifreeze temperature decreases, the antifreeze in the overflow structure will flow back to the water tank again, ensuring that the water level in the water tank does not drop, thereby maintaining the normal operation of the cooling system.

[0038] In addition, since the overflow lower shell 202 is integrally formed with the air filter housing 10 inside the accommodating space 103 of the air filter housing 10, the volume of the air filter overflow device 100 can be reduced, that is, the volume of the air filter overflow device 100 is only the volume of the air filter housing 10. When the air filter overflow device 100 is applied to the engine, the space occupied by the air filter overflow device 100 can be reduced, thereby further facilitating the setting of the air filter overflow device 100.

[0039] In addition, since the overflow lower shell 202 and the air filter housing 10 are integrally formed structural parts, the overflow upper shell 201 is located above the overflow lower shell 202 and is connected to the overflow lower shell 202. After the air filter structure is arranged in the engine compartment, the setting of the overflow structure can be completed at the same time. In this way, there is no need to set a mounting bracket when the overflow structure is arranged in the engine compartment, which can further facilitate the assembly of the vehicle and reduce the weight of the entire vehicle.

[0040] Furthermore, by arranging the overflow upper shell 201 above the overflow lower shell 202, the overflow upper shell 201 and the overflow lower shell 202 can jointly define a storage space 203, and the storage space 203 can be used to store the coolant of the engine.

[0041] In some embodiments of the present invention, the overflow lower shell 202 and the air filter housing 10 can be integrally formed by injection molding.

[0042] Combination Figure 2 , Figure 3 and Figure 6 As shown, the air filter housing 10 includes an air filter upper shell 101 and an air filter lower shell 102, the air filter upper shell 101 is located above the air filter lower shell 102 and connected to the air filter lower shell 102, and the overflow lower shell 202 and the air filter lower shell 102 are integrally formed structural parts. Specifically, by arranging the air filter upper shell 101 above the air filter lower shell 102, and connecting the air filter upper shell 101 and the air filter lower shell 102, the overflow lower shell 202 and the air filter lower shell 102 are arranged as an integrally formed structural part, which can not only ensure the stability of the overflow lower shell 202, but also after opening the air filter upper shell 101, the overflow lower shell 202 and the components in the air filter lower shell 102 can be inspected, and the structural design of the air filter overflow device 100 can be further optimized.

[0043] Combination Figure 1 , Figure 2 and Figure 3 As shown, the portion of the air filter upper shell 101 corresponding to the overflow lower shell 202 is provided with an avoidance groove 109, and the overflow upper shell 201 is located in the avoidance groove 109. Specifically, by arranging the overflow upper shell 201 in the avoidance groove 109, it is possible to prevent the overflow upper shell 201 from protruding from the air filter housing 10, resulting in an unnecessary increase in the volume of the air filter overflow device 100. In addition, in this way, the air filter upper shell 101 can also play a certain protective role on the overflow upper shell 201, thereby further improving the reliability of the air filter overflow device 100.

[0044] The setting of the avoidance groove 109 can effectively improve space utilization, avoid idle space, make the structure of the air filter overflow device 100 more compact, reduce the layout difficulty to a certain extent, and improve the accuracy and stability of the structure of the air filter overflow device 100.

[0045] It should be noted that the part of the air filter upper shell 101 corresponding to the avoidance groove 109 is sealed and connected to the overflow upper shell 201, which can prevent the air in the accommodating space 103 from leaking outward from the avoidance groove 109 and reducing the engine's intake efficiency, thereby ensuring the structural reliability of the air filter overflow device 100.

[0046] Combination Figure 3 , Figure 4 and Figure 7As shown, the air filter upper shell 101 is provided with a first perforation 107, and the air filter lower shell 102 is provided with a second perforation 108, the first perforation 107 and the second perforation 108 correspond to each other and are connected and fixed by fasteners. Specifically, the air filter housing 10 includes an air filter upper shell 101 and an air filter lower shell 102, the air filter upper shell 101 is provided with a first perforation 107, and the air filter lower shell 102 is provided with a second perforation 108, the first perforation 107 and the second perforation 108 correspond to each other in structure and position, and the first perforation 107 and the second perforation 108 are sequentially penetrated by fasteners, so that the air filter upper shell 101 and the air filter lower shell 102 are connected, which can not only improve the stability of the connection and fixation of the air filter upper shell 101 and the air filter lower shell 102, but also make the connection between the air filter upper shell 101 and the air filter lower shell 102 simple and direct. In addition, such an arrangement can also facilitate the disassembly of the air filter upper shell 101 and the air filter lower shell 102, thereby facilitating the replacement of the air filter element 104 in the accommodating space 103.

[0047] It should be noted that the first through hole 107 and the second through hole 108 may be threaded holes, and the fasteners may be screws.

[0048] Combination Figure 3 , Figure 4 and Figure 7 As shown, there are multiple first perforations 107 and multiple second perforations 108, and the multiple first perforations 107 correspond to the multiple second perforations 108. Specifically, by setting the first perforations 107 and the second perforations 108 to multiple, not only can the stability and reliability of the connection and fixation between the overflow upper shell 201 and the overflow lower shell 202 be further improved, but also by setting the multiple first perforations 107 on the air filter upper shell 101 at intervals, and setting the multiple second perforations 108 on the air filter lower shell 102 at intervals, the force between the air filter upper shell 101 and the air filter lower shell 102 can be made more uniform.

[0049] Combination Figure 1 , Figure 4 and Figure 5 As shown, the overflow upper shell 201 is welded and fixed to the overflow lower shell 202. Specifically, by welding and fixing the overflow upper shell 201 and the overflow lower shell 202, not only can the strength and stability of the connection and fixation between the overflow upper shell 201 and the overflow lower shell 202 be ensured, but also the connection between the overflow upper shell 201 and the overflow lower shell 202 can be simple and direct.

[0050] Combination Figure 3 , Figure 4 and Figure 5As shown, an overflow pipe is provided on the overflow upper housing 201, and the overflow pipe is connected to the storage space 203. An air inlet 105 and an air outlet 106 are provided on the air filter lower housing 102, and the accommodating space 103 is connected between the air inlet 105 and the air outlet 106. Specifically, the air inlet 105 and the air outlet 106 in the air filter device are both provided on the air filter lower housing 102, and the external air enters the air filter device through the air inlet 105, and the air processed by the air filter device flows out through the air outlet 106.

[0051] In addition, the accommodating space 103 is connected between the air inlet 105 and the air outlet 106, and an air filter 104 is arranged in the accommodating space 103. The air that has not been processed by the air filter 104 is accommodated between the air inlet 105 and the air filter 104, and the air that has been processed by the air filter 104 is accommodated between the air filter 104 and the air outlet 106. When the gas in the accommodating space 103 is insufficient, the external air enters the air filter device through the air inlet 105 for air replenishment, and after being processed by the air filter device, flows to the air outlet 106, and then flows into the engine. In this way, sufficient and clean air can be provided to the engine, which can ensure the normal operation of the vehicle engine and extend its service life to a certain extent.

[0052] Furthermore, the storage space 203 is used to store antifreeze. When the engine temperature rises, the antifreeze will expand and exceed the capacity of the water tank. At this time, the antifreeze will enter the storage space 203 through the overflow pipe, so that the storage space 203 stores excess antifreeze.

[0053] As the temperature of the antifreeze liquid decreases, the antifreeze liquid in the storage space 203 will flow back to the water tank again, ensuring that the water level of the water tank does not drop, thereby maintaining the normal operation of the cooling system.

[0054] Combination Figure 1 As shown, there are multiple air filters 104, and the multiple air filters 104 are arranged at intervals in the accommodation space 103. Specifically, by arranging multiple air filters 104, it is possible to ensure the filtering efficiency of the air filter 104 on the air while facilitating the independent replacement of the multiple air filters 104, and it is possible to facilitate the installation and arrangement of the air filter 104 in the accommodation space 103.

[0055] In some embodiments of the present invention, there may be two air filters 104 , and the two air filters 104 are horizontally spaced apart in the accommodating space 103 .

[0056] Combination Figure 1As shown, there are multiple air inlets 105 and multiple air outlets 106, and each air filter 104 corresponds to one air inlet 105 and one air outlet 106. Specifically, multiple air inlets 105 and multiple air outlets 106 are provided, and each air filter 104 corresponds to one air inlet 105 and one air outlet 106. Air enters the accommodation space 103 from multiple air inlets 105, and passes through multiple air filters 104 corresponding to multiple air inlets 105 one by one, and after being filtered by multiple air filters 104, it flows out from multiple air outlets 106 corresponding to multiple air filters 104 one by one, so that the smoothness of air flow can be improved under the premise of ensuring the filtering efficiency of air.

[0057] Combination Figure 1 , Figure 5 and Figure 7 As shown, the air filter 104 is provided with an avoidance notch 110, and the avoidance notch 110 avoids the overflow lower shell 202. Specifically, the air filter 104 and the overflow lower shell 202 are both arranged in the air filter housing 10. By arranging the avoidance notch 110 on the air filter 104, and the avoidance notch 110 avoids the overflow lower shell 202, the rationality and compactness of the structural arrangement of the accommodating space 103 can be ensured, the volume increase of the air filter housing 10 can be avoided, and the structural design in the accommodating space 103 can be further optimized.

[0058] Furthermore, after the air filter overflow device 100 is arranged in the engine compartment, the bottom of the air filter lower shell 102 needs to avoid the relevant components in the engine compartment, and the part of the bottom of the air filter lower shell 102 that does not need to avoid the relevant components is protruded downward. In this way, the volume of the accommodating space 103 can be increased while ensuring that the air filter overflow device 100 avoids the relevant components in the engine compartment, thereby improving the engine's intake efficiency.

[0059] Combination Figure 2 , Figure 5 and Figure 6As shown, the accommodating space 103 and the storage space 203 are separated from each other. Specifically, the air filter upper shell 101 and the air filter lower shell 102 are connected and fixed, together forming the air filter housing 10 and defining the accommodating space 103, the overflow upper shell 201 and the overflow lower shell 202 together forming the overflow housing 20 and defining the storage space 203, the storage space 203 is arranged in the accommodating space 103, but the accommodating space 103 and the storage space 203 are isolated from each other, and the two are not connected, the accommodating space 103 mainly accommodates the air before and after filtration, and the storage space 203 mainly stores the coolant generated by the vehicle, the two are separated from each other and play their own role, so that the liquid in the storage space 203 and the gas in the accommodating space 103 can be avoided from affecting each other, and can ensure that each plays a better role, and can improve the working performance and stability of the vehicle.

[0060] The vehicle according to the utility model may mainly include: the above-mentioned air filter overflow device 100. Specifically, since the structure of the air filter overflow device 100 is more compact and has good working performance, the air filter overflow device 100 is applied to the vehicle, which can effectively reduce the space for installing the air filter overflow device 100 in the vehicle, thereby optimizing the structural design of the vehicle, improving the working performance of the vehicle, and improving the user experience.
