[0067] The purpose of the present disclosure is to provide a filter base 100, a filter assembly and a vehicle. The filter base 100 is used for the filter assembly and the vehicle, can improve the strength and rigidity of the base body 110, and can improve the molding performance of the filter base 100, so as to at least solve the related technical problems.

[0068] In order to achieve the above purpose, Figures 1 to 10 As shown, an embodiment of the present disclosure provides a filter base 100 , which includes a base body 110 and a first reinforcing rib structure 120 .

[0069] The base body 110 includes a first body portion 112, a second body portion 111, and a transition portion 113 between the first body portion 112 and the second body portion 111. The transition portion 113 is recessed from the first side surface 110a of the base body 110 toward the second side surface 110b and extends along the first direction. The first body portion 112 is formed with an installation space 1121 for installing the filter element assembly 200. The installation space 1121 is recessed from the second side surface 110b toward the first side surface 110a. The first body portion 112 is formed with a through hole 1122 connected to the installation space 1121. The first reinforcing rib structure 120 includes a plurality of first reinforcing ribs 121 extending along the second direction and connected to the second body portion 111, the transition portion 113, and the second body portion 111 at intervals along the first direction.

[0070] Through the above technical solution, the filter base 100 disclosed in the present invention includes a base body 110 formed by a first body part 112, a second body part 111 and a transition part 113 connecting the first body part 112 and the second body part 111, wherein the transition part 113 is recessed from the first side surface 110a toward the second side surface 110b, and the first body part 112 is formed with an installation space 1121 for installing the filter element assembly 200, and is formed with a through hole 1122 connected to the installation space 1121, so that air enters from one side of the installation space 1121 and enters the interior of the vehicle through the through hole 1122 after being filtered by the filter element assembly 200, so as to realize the filtering function of the external air; at the same time, the first body part 112, the transition part 113 and the second body part 111 are also connected by a plurality of first reinforcing ribs 121, thereby improving the strength and rigidity of the base body 110 (i.e., the first body part 112 and the second body part 111), and can improve the molding performance of the filter base 100.

[0071] It should be noted that, in order to further improve the strength and rigidity, the multiple first reinforcing ribs 121 may be connected by multiple auxiliary ribs, and the multiple auxiliary ribs may extend along the first direction or may be in other forms, which are not specifically limited here.

[0072] Considering the lightness of the filter base 100, Figure 1 As shown, in some embodiments of the present disclosure, at least part of the first reinforcing rib 121 is formed with a groove G that is recessed toward the transition portion 113 on the side facing away from the transition portion 113. The groove G is provided on the first reinforcing rib 121 to reduce the weight of the filter base 100 while ensuring strength and rigidity. It should be noted that the position of the groove G can correspond to the transition portion 113, and can be the same or similar to the curved shape of the transition portion 113, that is, it can be made into a conformal design to achieve greater lightness in the greatest possible case.

[0073] It is worth noting that the above-mentioned groove portion G may be provided on a portion of the first reinforcing rib 121 to ensure the connection strength and rigidity between the first body portion 112 and the second body portion 111 .

[0074] In order to observe or repair other components below the filter base after it is installed in the vehicle, Figure 2 and Figure 3As shown, in some embodiments, a first opening 1111 is formed on one side of the second body portion 111 away from the first body portion 112, and a shielding member 130 is openably installed in the first opening 1111. By providing the first opening 1111, relevant personnel can repair the components below the installed filter base 100. At the same time, an openable shielding member 130 is provided at the first opening 1111 for normal sealing and shielding.

[0075] It should be noted that the shielding member 130 can be openably installed at the first opening 1111 in any suitable manner, such as snap-on, plug-in or screw connection. Optionally, one end of the shielding member 130 is rotatably connected to the side of the first opening 1111 close to the transition portion 113, and the shielding member 130 can be unlockably locked at the edge of the first opening 1111 in the first direction. The shielding member 130 can be installed at the first opening 1111 in a rotating connection + snap-on manner. Among them, one end of the shielding member 130 can be rotatably connected to the opposite two side walls in the first direction of the side of the first opening 1111 close to the transition portion 113, and the other end or the position close to the other end can be provided with a buckle 131, which can be snap-fitted into the clamping groove 1112 of the opposite two side walls in the first direction of the side of the first opening 1111 away from the transition portion 113, thereby realizing the unlockable locking of the shielding member 130 at the first opening 1111.

[0076] In some embodiments, the first opening 1111 is located in the middle of the second main body 111 in the first direction and between two adjacent first reinforcing ribs 121. A second reinforcing rib 122 connecting the two adjacent first reinforcing ribs 121 is provided on one side of the first opening 1111 close to the transition portion 113. The two first reinforcing ribs 121 located on both sides of the first opening 1111 may not be designed with the lightweight groove G mentioned above to ensure that the area has sufficient anti-deformation ability. In addition, in order to further improve the strength and stiffness of the area, the second reinforcing rib 122 may be used to connect the two first reinforcing ribs 121 to prevent the first opening 1111 from being damaged due to rotation or pulling.

[0077] In order to further improve the strength and rigidity of the second reinforcing rib 122 and the transition portion 113 corresponding to the second reinforcing rib 122, as shown in FIG. Figure 3 As shown, in some other embodiments, the first reinforcing rib structure 120 may further include a third reinforcing rib 123 connected to the second reinforcing rib 122, the transition portion 113 and the first body portion 112. There may be a plurality of third reinforcing ribs 123, which are arranged at intervals along the first direction, and each third reinforcing rib 123 is respectively connected to the second reinforcing rib 122, the transition portion 113 and the first body portion 112, and extends toward the through hole 1122 of the first body portion 112.

[0078] In order to further reduce the weight, a groove portion G may be formed on the side of the third reinforcing rib 123 away from the transition portion 113 to reduce the weight while satisfying the strength and rigidity.

[0079] In order to achieve the connection between the filter base 100 and the vehicle, as shown in FIG. Figure 4 and Figure 6 As shown, in some embodiments, the filter base 100 further includes a first mounting portion 140 and a second mounting portion 150 for connecting with the triangular beam; the first mounting portion 140 is arranged on the side of the first body portion 112 in the first direction and extends in a direction away from the first body portion 112; the second mounting portion 150 is arranged on a side of the second body portion 111 away from the first body portion 112. After the filter element assembly 200 is installed, the filter base 100 is connected to the interior of the front cabin of the vehicle through the triangular beam. It should be noted that the first mounting portion 140 and the second mounting portion 150 can be constructed using any suitable structure. For example, screws or bushings can be used for connection.

[0080] Since the installation point is usually a location with high stress and prone to failure, sufficient strength and rigidity need to be ensured. In some embodiments, the filter base 100 may also include a second reinforcing rib structure, which connects the second installation portion 150 and the second body portion 111 to improve the strength of the second installation portion 150.

[0081] The second reinforcing rib structure can adopt any suitable structure, such as Figure 5 As shown, in some embodiments, the second reinforcing rib structure includes a plurality of fourth reinforcing ribs 161 extending radially in a direction away from the second mounting portion 150, and a fifth reinforcing rib 162 connecting the plurality of fourth reinforcing ribs 161. The plurality of fourth reinforcing ribs 161 may extend from the second mounting portion 150 in an umbrella shape, for example, in a direction away from the second mounting portion 150, and the fifth reinforcing rib 162 may connect the plurality of fourth reinforcing ribs 161 and be arranged in an arc shape around a portion of the circumference of the second mounting portion 150. It should be noted that the fifth reinforcing rib 162 may be multiple and arranged at intervals in a direction away from the second mounting portion 150, for force transmission and coupling between the plurality of divergent fourth reinforcing ribs 161.

[0082] In some embodiments, at least a portion of the fourth reinforcement rib 161 extends to the first main body portion 112 and is respectively connected to the transition portion 113 and the first main body portion 112; because the second mounting portion 150 can be located at the edge or near the edge in the second direction of the second main body portion 111, the second mounting portion 150 and the second main body portion 111 are connected by the fourth reinforcement rib 161 and then extend toward the middle direction of the first main body portion 112, or are directly overlapped, which can increase the stiffness of the middle area of ​​the second main body portion 111 and improve the vibration fatigue performance of the second main body portion 111 under external excitation.

[0083] At least one fourth reinforcing rib 161 is connected to the first reinforcing rib 121 at the edge of the second main body portion 111 in the first direction. The thickness of the fourth reinforcing rib 161 at this location can be increased, for example, twice the conventional thickness. The second mounting portion 150 and the first reinforcing rib 121 are connected by the fourth reinforcing rib 161, so that the force received by the second mounting portion 150 can be directly transmitted to the first main body portion 112 through the fourth reinforcing rib 161, and the force transmission is continuous and the support is direct, which can greatly improve the overall mode and reduce the stress level of the entire structure.

[0084] It should be noted that the fourth reinforcing rib 161 partially connected to the second mounting portion 150 and the first main body portion 112 may also be provided with, for example, the above-mentioned groove portion G at a position corresponding to the transition portion 113 to achieve lightweighting.

[0085] In some embodiments, the second mounting portion 150 may be configured as a first columnar structure 151 having a mounting hole and having a bottom end connected to the second body portion 111, and the fourth reinforcing rib 161 extends obliquely from the bottom end of the first columnar structure 151 toward the top end. Since the fourth reinforcing rib 161 extends from the bottom of the first columnar structure 151 to the top area of ​​the first columnar structure 151, it is equivalent to forming a plurality of vertical ribs on the side wall of the first columnar structure 151, and the vertical ribs are arranged obliquely, which can better disperse the force at the mounting hole to the plurality of fourth reinforcing ribs 161.

[0086] In some embodiments, the first mounting portion 140 includes a mounting body 141 and a second columnar structure 142 provided on the mounting body 141 and having a mounting hole; the filter base 100 further includes a third reinforcing rib structure 170, and the third reinforcing rib structure 170 connects the second columnar structure 142 and the edge of the mounting body 141. The first mounting portion 140 can be configured as, for example, an ear-shaped support foot design, and the second columnar structure 142 and the edge of the mounting body 141 are connected by the third reinforcing rib structure 170, so that the mounting body 141 can be made thinner, and the purpose of lightweight can be achieved while ensuring rigidity.

[0087] In order to further achieve lightweight, optionally, the third reinforcing rib structure 170 includes a plurality of sixth reinforcing ribs 171; the plurality of sixth reinforcing ribs 171 respectively connect the outer side wall of the second columnar structure 142 and the edge of the mounting body 141; a weight-reducing hole 1411 is provided between two adjacent sixth reinforcing ribs 171. Among them, the weight-reducing hole 1411 can be provided on the non-critical force-bearing side of the mounting body 141, and there can be multiple weight-reducing holes 1411. At the same time, in order to improve the bearing capacity and have sufficient stiffness performance under small impact, the sixth reinforcing ribs 171 are arranged between the weight-reducing holes 1411, and the sixth reinforcing ribs 171 are used to ensure strength and stiffness, and the weight-reducing holes 1411 are used to achieve actual lightweight.

[0088] Optionally, at least part of the sixth reinforcing rib 171 is connected to the first body portion 112 and extends toward the interior of the first body portion 112; the sixth reinforcing rib 171 located in the first body portion 112 is connected through the auxiliary reinforcing rib 172. The sixth reinforcing rib 171 extends to the first body portion 112, increases the support stiffness of the first body portion 112, and increases the fatigue resistance and mode under small loads.

[0089] Since the transition device base is located below the front cover of the vehicle when applied to the vehicle, it needs to be able to collapse to maximize the protection of pedestrians when a pedestrian collision occurs. Optionally, the area of ​​the first mounting portion 140 close to the first main body portion 112 is provided with a collapse structure 143 for collapsing and absorbing energy. Among them, the junction between the mounting body 141 and the first body can be the narrowest, which is the key force transmission part. Under a transient large impact, it is necessary to collapse and deform to absorb energy, and this area needs to be weakened. Therefore, the collapse structure 143 is set at this position to achieve the protection function in the above situation.

[0090] The design of at least part of the sixth reinforcing rib 171 extending to the first main body portion 112 can also ensure that the first main body portion 112 has sufficient rigidity under a large impact, and collapse occurs from the collapse structure 143, thereby increasing the robustness of the collapse energy absorption mode.

[0091] The collapse structure 143 can be constructed in any suitable structure. Optionally, the collapse structure 143 includes a through hole 1431 provided with the mounting body 141; and / or, the collapse structure 143 includes an induction groove 1432 provided on the side of the mounting body 141 and the sixth reinforcing rib 171. The collapse structure 143 can be a plurality of through holes 1431 formed on the mounting body 141 and arranged at intervals along the first direction to reduce the rigidity connection at this position. On the other hand, the induction groove 1432 can also be provided on the side of the mounting body 141 and the sixth reinforcing rib 171, wherein the induction groove 1432 and the through hole 1431 can be opposite in space, that is, both can be arranged along the first direction.

[0092] In order to fix the filter element assembly 200 at the installation space 1121, in some embodiments, the two opposite sides of the installation space 1121 in the second direction are respectively provided with fixing parts 180 for fixing the filter element assembly 200. For example, five fixing parts 180 can be respectively provided on the two sides of the installation space 1121 in the second direction for installing the filter element assembly 200. The fixing parts 180 include but are not limited to stud structures.

[0093] Among them, a seventh reinforcing rib 191 is provided between the fixing portion 180 and the inner side wall of the installation space 1121; and / or, an eighth reinforcing rib 192 connected to the inner side wall of the installation space 1121 is provided between two adjacent fixing portions 180. The fixing portion 180 can be integrally formed with the first body portion 112, and it can extend into the installation space 1121. In order to improve the connection strength of the fixing portion 180, a seventh reinforcing rib 191 can be provided between the fixing portion 180 and the inner side wall of the installation space 1121, so as to further reduce the material and improve the lightweight level.

[0094] In addition, an eighth reinforcing rib 192 may be provided on the inner wall of the installation space 1121 between the two fixing points to further enhance the edge strength and rigidity of the installation space 1121 .

[0095] Optionally, the seventh reinforcing rib 191 and / or the eighth reinforcing rib 192 are provided with an arc-shaped portion 193, and the arc-shaped portion 193 is recessed toward the inner side wall of the installation space 1121. The seventh reinforcing rib 191 and the eighth reinforcing rib 192 can be designed to have an arc-shaped free edge, which can correspond to the contour of the outer fixing portion 180 and be integrated, and can facilitate the spatial arrangement of the filter element assembly 200.
