[0033] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0035] In the present disclosure, unless otherwise stated, directional words such as "front, back, up, and down" are generally defined when the air filter provided by the present disclosure is normally installed, and "front and back" can refer to Figure 6 In the direction indicated by the arrows, "inside" and "outside" refer to the inside and outside of the corresponding component outline. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in this disclosure are to distinguish one element from another element and have no order or importance.

[0036] In order to achieve pedestrian protection, the present disclosure has made relevant designs on the structure of the air filter housing 1, such as Figure 1 As shown, the shell 1 is provided with a collapse structure 10. When impacted by an external force, the collapse structure 10 can be deformed in a horizontal direction toward the outside of the shell 1. The collapse structure 10 can be provided on the side wall of the shell 1, such as Figure 2 , Figure 6 and Figure 7 As shown, in the embodiment provided by the present disclosure, the shell 1 includes first side walls arranged opposite to each other in the width direction, and a collapse structure 10 is provided on at least one of the two first side walls. The collapse structure 10 can be provided on the first side wall at the rear, and the collapse structure 10 can be deformed toward the outside of the shell 1 along the width direction. Of course, the present disclosure also includes an embodiment in which the collapse structure 10 is respectively provided on two second side walls adjacent to the first side wall, that is, two second side walls opposite to each other in the length direction, and the collapse structure 10 can be deformed toward the outside of the shell 1 in the length direction, which all belong to the protection scope of the present disclosure.

[0037] In the embodiment provided by the present disclosure, by designing the structure of the shell 1 itself, the collapse structure 10 can play the role of collapse energy absorption. When a collision occurs, the pedestrian's head first hits the engine cover, and the engine cover further hits the shell 1. The shell 1 deforms outward to collapse and absorb energy, reducing damage to the head and achieving pedestrian protection. In addition, the distance between the engine cover and the shell 1 does not need to be too large, and the engine cover can be lowered to ensure the driver's field of vision, which can meet the requirements of pedestrian protection and the field of vision requirements.

[0038] The collapse structure 10 may be any suitable structure. In the present disclosure, the housing 1 includes a lower housing 11 and an upper housing 12, and the collapse structure 10 may be disposed at the rear of the lower housing 11, such as Figure 6 and Figure 7 As shown, the collapse structure 10 may include an inclined surface inclined outwardly along the thickness direction of the shell 1, and the shell 1 forms a collapse cavity at the inclined surface. The upper part of the inclined surface is arranged backward to form a collapse cavity 100. The rear end of the shell 1 is made into an inclined surface. When a collision occurs, the direction of the external force is from top to bottom. The collapse cavity 100 formed by the inclined surface is more conducive to deformation toward the outside of the shell 1 (the deformation direction is as shown in FIG. Figure 7 In other embodiments, the collapse structure 10 can also be other structures that are easy to deform, such as forming an irregularly shaped collapse cavity 100, opening a slit on the shell 1, etc., which can also play the role of collapse energy absorption. The collapse structure 10 is arranged at the rear end of the shell 1. Of course, the collapse structure 10 can also be designed on both sides and the front end in the length direction. The embodiment in which the collapse structure 10 is only arranged at the rear can reduce the occupied space of the shell 1.

[0039] like Figure 7 As shown, the collapse structure 10 includes a bend section 101 located at the upper part, a support section 103 located at the lower part, and an inclined section 102 located between the bend section 101 and the support section 103. The support section 103 has a vertical section and a horizontal section connected to each other. The bend section 101 and the inclined section form an angle with each other, and the inclined section 102 and the vertical section of the support section 103 form an angle with each other. A local thickness thinning line is formed at the connection between the support section 103 and the inclined section 102. The connection points of multiple bend sections 101 and the positions of the thinning lines are prone to deformation. Specifically, the structure of the inclined surface can be designed according to needs to balance the structural strength of the shell 1 and the ease of deformation. The number of bend sections 101 and inclined sections 102 is not limited. In this embodiment, the bend section 101 is a plurality of sections, and the plurality of bend sections 102 form angles with each other.

[0040] In order to achieve the fixing of the air filter, Figure 1As shown, mounting feet 13 are respectively provided on both sides of the length direction of the housing 1, and fixing holes 130 for fasteners to pass through are provided on the mounting feet 13 to fix the air filter in a suitable position, such as on the vehicle body. In the present disclosure, a weakening structure is provided on at least one side of the mounting feet 13, and when a collision occurs, the weakening structure can further increase the deformation of the housing 1, further play the role of crushing energy absorption, reduce the impact force on the head, and better meet the needs of pedestrian protection.

[0041] The weakening structure can be any suitable structure. In an exemplary embodiment of the present disclosure, Figure 8 As shown, the weakening structure includes a plurality of weakening holes 131, and the plurality of weakening holes 131 are arranged at intervals in the circumferential direction around the fixing hole 130. The weakening holes 131 may be openings of various irregular shapes such as round holes, square holes, and elongated holes, which can reduce the structural strength of the mounting foot 13. When a collision occurs, the mounting foot 13 itself may be deformed or even broken, playing the role of collapsing and absorbing energy.

[0042] In another exemplary embodiment of the present disclosure, the weakening structure includes a slot 132 provided on the mounting foot 13. The position and shape of the slot 132 are not specifically limited, and it also plays a role in reducing the rigidity of the mounting foot 13. The present disclosure includes an embodiment in which both the weakening hole 131 and the slot 132 are provided, and also includes an embodiment in which only one of them is provided, which can be specifically designed according to the requirements of pedestrian protection.

[0043] In this embodiment, if Fig. 9 As shown, the slot 132 is provided at the connection between the mounting foot 13 and the housing 1, and the slot is provided on the bottom surface of the mounting foot 13. The slot 132 may be a V-shaped slot with the opening facing downward. In other embodiments, it may also be a U-shaped slot.

[0044] In this disclosure, Fig. 9 As shown, the mounting foot 13 is provided with a reinforcing rib 133 , which can be arranged on the bottom surface of the mounting foot 13 to ensure that the reinforcing rib 133 will not fail when stimulated by the road surface during normal driving of the vehicle.

[0045] According to the second aspect of the present disclosure, a high efficiency air filter is also provided, comprising a housing 1 and a filter element 2 arranged in the housing 1. The housing 1 may be the housing of the air conditioning filter described above. The air filter has all the beneficial effects of the above housing, which will not be described in detail here.

[0046] The air filter provided by the present disclosure is a double-layer filter element. Figures 2 to 6As shown, the filter element 2 includes a first filter element 21 and a second filter element 22. The first filter element 21 is fixed in the lower shell 11 through a pressing plate 3. The upper shell 12 presses the second filter element 22 onto the pressing plate 3 and is connected to the lower shell 11 through fasteners. The filter element 2 is arranged in the limited space of the shell 1 and can filter dust and suspended matter in the air, thereby ensuring the quality of the air in the car. The middle pressing plate 3 sticks the first filter element 21 together. The outer periphery of the pressing plate 3 is provided with a rubber part, which is pressed on the surrounding frame of the lower shell 11. The second filter element 22 is placed on the pressing plate 3. The upper shell 12 is connected to the lower shell 11 through five front and rear screws, which press the second filter element 22 firmly and stably install the double-layer filter element in the shell 1.

[0047] In the present disclosure, in the width direction, the lower shell 11 has an extension 111 extending beyond the upper shell 12, and a seal is provided on the top surface of the extension 111 and / or the top surface of the upper shell 12. The seal includes a foam 112 provided on the periphery of the front end of the lower shell 11 and a soft rubber 121 provided on the periphery of the rear end of the upper shell 12. When the air filter is installed on the vehicle body, the seal plays a sealing role by pre-pressing the seal. In addition, since the rear end of the shell 1 is provided with an inclined surface, in the thickness direction, the upper shell 12 will be higher than the extension 111. The design of the foam 112 at the front end can reduce the height difference between the front and rear ends, thereby ensuring the stability of the air filter when it is installed horizontally.

[0048] According to a third aspect of the present disclosure, a vehicle is provided, comprising the air filter provided by the present disclosure. The vehicle has all the beneficial effects of the above-mentioned housing and air filter, which will not be described in detail herein.

[0049] In the present disclosure, the air filter is arranged in a transverse manner, the Z-direction distance between the engine cover and the air filter can be very small, and the engine cover is lowered, which will not affect the driver's field of vision. At the same time, the collapse structure 10 on the shell 1 and the weakening structure on the mounting foot 13 can both help the shell 1 to deform when hit, collapse and absorb energy, and reduce damage to pedestrians. The design of the double-layer filter element can effectively ensure the quality of the air in the car, and the double-layer filter element is easy to replace and simple to operate.
