[0052] The mounting base 110 according to the embodiment of the present application will be described below with reference to the accompanying drawings.

[0053] 3 , 4 , and 6 , a first mounting portion 111 for securing the mounting base 110 to the vehicle body is provided on the front side of the mounting base 110, and a second mounting portion 112 and a third mounting portion 113 are provided on the rear side of the mounting base 110. The second mounting portion 112 is used to secure the rear bumper 200, and the third mounting portion 113 is used to secure the spoiler 120. This means that the first mounting portion 111 for securing the mounting base 110 to the vehicle body is provided on the front side of the mounting base 110, and the second mounting portion 112 for securing the rear bumper 200 to the mounting base 110 and the third mounting portion 113 for securing the spoiler 120 to the mounting base 110 are provided on the rear side of the mounting base 110.

[0054] It should be noted that, in the prior art, the mounting base 110 of the diffuser 100 is usually fixed to the rear bumper 200. Since the rear bumper 200 is usually made of plastic, the weight of the rear bumper 200 will be increased, causing the rear bumper 200 to have a risk of sinking, and fatigue damage will occur after a period of time, affecting the quality of the vehicle 10000 and even endangering the safety of the driver and passengers.

[0055] To solve the above problems, the present application provides a first mounting portion 111 on the front side of the mounting seat 110 for fixing the mounting seat 110 to the vehicle body, so as to fix the mounting seat 110 of the diffuser 100 on the vehicle body. Since the vehicle body is usually made of a material with high structural strength, the vehicle body can be effectively utilized to fix the mounting seat 110 to improve the position stability of the mounting seat 110, thereby ensuring the working performance of the mounting seat 110. At the same time, it can also avoid the weight of the rear bumper 200 being increased due to the provision of the mounting seat 110, which would cause the rear bumper 200 to sink at risk, thereby ensuring the working performance of the rear bumper 200 and extending the service life of the rear bumper 200.

[0056] At the same time, the present application also provides a second mounting portion 112 for mounting the rear bumper 200 on the rear side of the mounting seat 110. The second mounting portion 112 can be used to fix the rear bumper 200 on the mounting seat 110, thereby fixing the rear bumper 200 to the vehicle body, so as to use the vehicle body to fix the rear bumper 200, improve the position stability of the rear bumper 200, and to a certain extent avoid the looseness, abnormal noise and sinking of the rear bumper 200 during driving, thereby ensuring the working performance of the rear bumper 200.

[0057] That is to say, the body and rear bumper 200 of the vehicle 10000 of the present application are respectively arranged on the front and rear sides of the mounting seat 110, so that the diffuser 100 is arranged between the body and the rear bumper 200 of the vehicle 10000. In this way, while using the body to support the diffuser 100, the rear bumper 200 can also be directly used to block the installation point between the mounting seat 110 and the body, eliminating the need for a beautification panel. While ensuring the appearance quality of the vehicle 10000, it can also simplify the structure of the vehicle 10000, reduce the manufacturing cost of the vehicle 10000, and reduce the weight of the vehicle 10000, thereby achieving lightweighting of the vehicle 10000.

[0058] In addition, by providing a third mounting portion 113 on the rear side of the mounting base 110, the spoiler 120 can be provided on the mounting base 110. Since the mounting base 110 is stably connected to the vehicle body, the mounting base 110 can be used to provide high-strength support for the spoiler 120 to ensure the structural stability of the spoiler 120, so that the spoiler 120 can operate smoothly and not fall off under complex working conditions, thereby facilitating the control of the spoiler 120 and utilizing the spoiler 120 to improve the air flow efficiency at the bottom of the vehicle 10000, thereby ensuring the working performance of the diffuser 100, so as to facilitate utilizing the diffuser 100 to improve the handling stability of the vehicle 10000.

[0059] As can be seen from the above structure, the mounting seat 110 of the embodiment of the present application can be installed on the vehicle body by providing a first mounting portion 111 for fixing to the vehicle body on the front side of the mounting seat 110, thereby realizing the use of the vehicle body to support the mounting seat 110. Since the structural strength of the vehicle body is relatively high, this can improve the position stability of the mounting seat 110 while also avoiding sinking and damage to the rear bumper 200 caused by the installation of the diffuser 100, thereby ensuring the working performance of the rear bumper 200 and extending the service life of the rear bumper 200.

[0060] By providing a second mounting portion 112 for mounting the rear bumper 200 on the rear side of the mounting seat 110, the mounting seat 110 can be positioned between the vehicle body and the rear bumper 200 while utilizing the vehicle body to support the rear bumper 200. In this way, the rear bumper 200 can be utilized to shield the mounting point between the mounting seat 110 and the vehicle body, eliminating the need for a beautification panel. This simplifies the structure of the vehicle 10000 and reduces the weight and manufacturing cost of the vehicle 10000 while ensuring the appearance quality of the vehicle 10000.

[0061] By providing a third mounting portion 113 on the rear side of the mounting seat 110, the spoiler 120 can be matched with the mounting seat 110, thereby facilitating the use of the spoiler 120 to improve the air flow efficiency at the bottom of the vehicle 10000, ensure the working performance of the diffuser 100, and thus ensure the handling stability of the vehicle 10000.

[0062] It can be understood that, compared with the prior art, the present application sets the mounting base 110 of the diffuser 100 between the body of the vehicle 10000 and the rear bumper 200. In this way, while the body is used to support the diffuser 100 and the rear bumper 200, the rear bumper 200 can also be used to shield the mounting point between the mounting base 110 and the body. While ensuring the appearance quality of the vehicle 10000, it can also simplify the structure of the vehicle 10000 and reduce the weight and manufacturing cost of the vehicle 10000.

[0063] In some embodiments, as shown in Figures 1 and 2, the spoiler 120 is rotatably matched with the third mounting portion 113 to enable the spoiler 120 to be rotatably mounted on the mounting base 110, thereby facilitating the control of the rotation of the spoiler 120, and utilizing the spoiler 120 to improve the air flow efficiency at the bottom of the vehicle 10000, ensure the working performance of the diffuser 100, and facilitate utilizing the diffuser 100 to improve the handling stability of the vehicle 10000.

[0064] In some embodiments, as shown in conjunction with FIG6 and FIG7 , the second mounting portion 112 includes a first boss 1121 protruding from the mounting base 110. The first boss 1121 is provided with a first mounting hole 1122. The rear bumper 200 is adapted to be abutted and fixed to the first boss 1121. This allows the rear bumper 200 to be connected to the mounting base 110, thereby facilitating support of the rear bumper 200 by the vehicle body, improving the positional stability of the rear bumper 200, and, to a certain extent, preventing the rear bumper 200 from becoming loose, making unusual noises, or sinking during driving, thereby ensuring the operating performance of the rear bumper 200.

[0065] In some embodiments, as shown in Figures 6 and 7, the second mounting portion 112 includes a plurality of first bosses 1121, and the plurality of first bosses 1121 are arranged at intervals on the mounting seat 110. The cooperation of the plurality of first bosses 1121 can increase the connection strength between the rear bumper 200 and the mounting seat 110, improve the position stability of the rear bumper 200, and ensure the working performance of the rear bumper 200.

[0066] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0067] In some embodiments, as shown in Figures 6, 7 and 9, the diffuser 100 includes a fastener 141, which passes through the rear bumper 200 and is fixedly connected to the first mounting hole 1122 of the first boss 1121 to fix the rear bumper 200 to the mounting base 110, thereby improving the position stability of the rear bumper 200.

[0068] The fastener 141 mentioned here may be a fastening screw.

[0069] It should be noted that by configuring the second mounting portion 112 to include a first boss 1121 protruding from the mounting seat 110, the thickness of the second mounting portion 112 can be increased, so that the second mounting portion 112 for fixing the rear bumper 200 has a certain thickness. In this way, threads can be directly tapped on the second mounting portion 112 to form a nut, and there is no need to weld a nut at a position on the mounting seat 110 that is opposite to the second mounting portion 112. In this way, while ensuring the connection accuracy between the mounting seat 110 and the rear bumper 200, the welding nut positioning tooling process can also be reduced, which facilitates processing and reduces the difficulty of connection.

[0070] It should also be noted that the above-mentioned setting can also achieve a fixed and detachable connection between the rear bumper 200 and the mounting base 110. Compared with the prior art in which the rear bumper 200 and the mounting base 110 are connected by bonding, clamping or welding, the connection strength between the rear bumper 200 and the mounting base 110 can be effectively improved, thereby preventing the rear bumper 200 from falling off and reducing material limitations. At the same time, it can also facilitate the disassembly of the rear bumper 200 and facilitate the maintenance of the rear bumper 200 and the diffuser 100.

[0071] In some embodiments, as shown in conjunction with FIG6 and FIG7 , the second mounting portion 112 further includes a mounting surface 1123 located below the first boss 1121. The mounting surface 1123 is provided with a second mounting hole 1124, and the rear bumper 200 is adapted to be abutted and fixed to the mounting surface 1123. This increases the contact area between the rear bumper 200 and the mounting base 110, thereby facilitating stable mounting of the rear bumper 200 on the mounting base 110, enabling the rear bumper 200 to be supported by the vehicle body, improving the positional stability of the rear bumper 200, and, to a certain extent, preventing the rear bumper 200 from becoming loose, making unusual noises, or sinking during driving, thereby ensuring the operating performance of the rear bumper 200.

[0072] The schematic diagram of the rear bumper 200 and the mounting base 110 after assembly can be seen in FIG11 .

[0073] In some embodiments, as shown in conjunction with Figures 6 and 7 , the mounting base 110 is provided with a second boss 1141 and / or a flange 115 to define a mounting surface 1123. This means that the second boss 1141 can be provided on the mounting base 110 to define the mounting surface 1123; or, the flange 115 can be provided on the mounting base 110 to define the mounting surface 1123; or, the second boss 1141 and the flange 115 can be provided on the mounting base 110 to define the mounting surface 1123. This reduces the difficulty of forming the mounting surface 1123, facilitates utilizing the mounting surface 1123 to increase the contact area between the rear bumper 200 and the mounting base 110, and enables the rear bumper 200 to be stably mounted on the mounting base 110.

[0074] In some embodiments, as shown in FIG. 7 , a portion of the mounting surface 1123 is defined by a flange 115 provided on the mounting seat 110 , and another portion of the mounting surface 1123 is defined by a second boss 1141 provided on the mounting seat 110 .

[0075] It should be noted that by using the second boss 1141 to define the mounting surface 1123, it is also beneficial to ensure the thickness of the mounting surface 1123, so that it is convenient to directly tap the threads on the mounting surface 1123 to form a nut, reducing the welding nut positioning tooling process, facilitating processing, and reducing the difficulty of connection.

[0076] At the same time, when the mounting surface 1123 is defined by the flange 115 provided on the mounting seat 110 , the thickness of the flange 115 can be adaptively increased to ensure the thickness of the mounting surface 1123 , making it easier to tap threads on the mounting surface 1123 .

[0077] In some embodiments, as shown in conjunction with Figures 2, 6, and 7, the third mounting portion 113 and the second mounting portion 112 share a mounting surface 1123, the first fastener 140 passes through the spoiler 120 and is fixed to the second mounting hole 1124, and the spoiler 120 is movable relative to the first fastener 140. In other words, the third mounting portion 113 and the second mounting portion 112 share the same mounting surface 1123, and the first fastener 140 passes through the spoiler 120 and is fixed to the second mounting hole 1124 to secure the spoiler 120 to the mounting base 110. Simultaneously, because the spoiler 120 is movable relative to the first fastener 140, the spoiler 120 is rotatable relative to the mounting base 110, thereby ensuring the working performance of the spoiler 120.

[0078] When the first fastener 140 is passed through the spoiler 120 and fixed to the second mounting hole 1124, the rear bumper 200 can be fixed to the mounting base 110 through the first fastener 140, thereby achieving the purpose of mounting the spoiler 120 and the rear bumper 200 on the mounting base 110 together through the first fastener 140, and clamping the rear bumper 200 between the spoiler 120 and the mounting base 110. This assembly method is not only simple and convenient but also has a firm connection, thereby enhancing the assembly accuracy and stability of the mounting base 110, the spoiler 120 and the rear bumper 200, and ensuring that the spoiler 120 can operate smoothly and not fall off under complex working conditions. On the other hand, it can also increase the strength of the rear bumper 200, effectively preventing the rear bumper 200 from loosening, making abnormal noises, and sinking during driving, thereby ensuring the working performance of the rear bumper 200.

[0079] In other words, the mounting seat 110 of the present application solves the technical problems in the prior art such as the loose connection and easy falling off of the rear bumper 200.

[0080] It is also worth noting that the present application uses a common mounting surface 1123 for the third mounting portion 113 and the second mounting portion 112, so that the second mounting portion 112 for mounting the rear bumper 200 and the third mounting portion 113 for mounting the spoiler 120 can be simultaneously provided on the rear side of the mounting seat 110, so as to rationally utilize the space on the rear side of the mounting seat 110, so that the rear bumper 200 and the spoiler 120 can be installed on the mounting seat 110 at the same time.

[0081] In some embodiments, the first fastener 140 is a fastening screw, which passes through the spoiler 120 and the rear bumper 200 in sequence and is fixed to the second mounting hole 1124 to achieve a detachable connection between the spoiler 120, the rear bumper 200 and the mounting base 110, thereby facilitating efficient installation and disassembly of the spoiler 120 and the rear bumper 200. At the same time, it can also ensure the connection strength of the spoiler 120, the rear bumper 200 and the mounting base 110, so that the spoiler 120 can operate smoothly and not fall off under complex working conditions, thereby extending the service life of the spoiler 120.

[0082] In some embodiments, as shown in Figures 4 and 5 , the first mounting portion 111 includes a transverse mounting portion 1111 and a longitudinal mounting portion 1112. The transverse mounting portion 1111 is provided with a transverse mounting hole, while the longitudinal mounting portion 1112 is provided with a longitudinal mounting hole. This allows the mounting base 110 to be mounted on the vehicle body using the transverse and longitudinal mounting holes, respectively, to achieve a fixed connection between the mounting base 110 and the vehicle body. This reduces the difficulty of connecting the mounting base 110 to the vehicle body while ensuring a high-quality connection.

[0083] At the same time, by setting the first mounting portion 111 to include a transverse mounting portion 1111 and a longitudinal mounting portion 1112, the mounting seat 110 can be fixedly connected to different surfaces of the vehicle body, thereby maximizing the connection strength between the mounting seat 110 and the vehicle body and improving the position stability of the mounting seat 110.

[0084] In some embodiments, as shown in conjunction with Figures 4 and 5 , the transverse mounting portion 1111 and the longitudinal mounting portion 1112 are respectively formed as bosses protruding from the mounting base 110. The bosses help ensure the structural strength of the transverse mounting portion 1111 and the longitudinal mounting portion 1112, ensuring that the transverse mounting portion 1111 and the longitudinal mounting portion 1112 can stably achieve a fixed connection between the mounting base 110 and the vehicle body. Furthermore, they also facilitate directly tapping threads on the transverse mounting portion 1111 and the longitudinal mounting portion 1112 to form nuts, eliminating the need to weld nuts on the transverse mounting portion 1111 and the longitudinal mounting portion 1112. This ensures the accuracy of the connection between the mounting base 110 and the vehicle body while reducing the process of welding nut positioning tooling, facilitating processing, and reducing connection difficulty.

[0085] In summary, the fixing method of the mounting base 110 of the present application to the vehicle body is simple, with high precision and reliable connection, and high efficiency in disassembly and installation.

[0087] Among them, the third fastener 142 and the fourth fastener 143 mentioned here can be fastening screws, so that while the mounting base 110 is fixedly connected to the vehicle body, the mounting base 110 can also be detachably connected to the vehicle body, making it easy to disassemble the mounting base 110 and reducing the difficulty of maintaining the mounting base 110.

[0088] In some embodiments, as shown in FIG12 , the mounting base 110 is further provided with a fixing portion 1194 for fixing the drive assembly 150. The drive assembly 150 is adapted to be connected to the spoiler 120 to drive the spoiler 120 to rotate. Here, the diffuser 100 includes the drive assembly 150 and the spoiler 120. The drive assembly 150 is disposed on the mounting base 110 via the fixing portion 1194 and connected to the spoiler 120, thereby allowing the spoiler 120 to rotate relative to the mounting base 110. This facilitates utilizing the spoiler 120 to improve the flow efficiency of air under the vehicle 10000, thereby ensuring the maneuverability and stability of the vehicle 10000.

[0089] In addition, by arranging the driving assembly 150 on the mounting base 110 , the mounting base 110 can also be used to support the driving assembly 150 to improve the position stability of the driving assembly 150 and facilitate ensuring the working performance of the driving assembly 150 .

[0090] In some embodiments, the drive assembly 150 is a drive motor, which is connected to the spoiler 120 to drive the spoiler 120 to rotate, thereby facilitating the use of the spoiler 120 to improve the flow efficiency of the air under the vehicle 10000 and ensure the handling stability of the vehicle 10000.

[0091] In some embodiments, in combination with Figures 6, 7 and 8, a fixing position 1194 is provided on the rear side of the mounting base 110, and a plurality of motor mounting holes 11942 are provided at the fixing position 1194. The drive assembly 150 is installed at the fixing position 1194 through the motor mounting holes 11942 to achieve the use of the mounting base 110 to support the drive assembly 150, improve the position stability of the drive assembly 150, and thus ensure the working performance of the drive assembly 150.

[0092] In some embodiments, a fastening screw passes through the drive assembly 150 and is installed in the motor mounting hole 11942 to enable the drive assembly 150 to be placed on the mounting base 110. While reducing the difficulty of fixing the drive assembly 150, the fixing strength can also be ensured, so that the position of the drive assembly 150 relative to the mounting base 110 is stable, thereby ensuring the working performance of the drive assembly 150.

[0093] In some embodiments, as shown in FIG8 , a plurality of limiting ribs 11941 are provided at the fixing position 1194 , and the limiting ribs 11941 are used to support the driving assembly 150 , thereby improving the position stability of the driving assembly 150 and enabling the driving assembly 150 to operate smoothly.

[0094] Optionally, the thickness of the limiting rib 11941 ranges from 5 mm to 7 mm to ensure that the limiting rib 11941 can effectively support the driving assembly 150 and improve the position stability of the driving assembly 150.

[0095] In some examples, the thickness of the limiting rib 11941 is 5 mm, 5.5 mm, 6 mm, 6.5 mm, or 7 mm, etc.

[0096] In some embodiments, as shown in FIG12 , the drive assembly 150 is connected to the spoiler 120 via a connecting rod assembly 160. The connecting rod assembly 160 includes a pivot shaft 161. The mounting base 110 is provided with a limiting boss 1142. The pivot shaft 161 is rotatably mounted on the limiting boss 1142. In other words, the drive assembly 150 is connected to the spoiler 120 via the pivot shaft 161 to ensure that the drive assembly 150 can effectively drive the spoiler 120 to rotate, reducing the difficulty of rotating the spoiler 120 and ensuring the spoiler 120's spoiling effect or other functional properties. This facilitates the use of the spoiler 120 to improve the flow efficiency of air under the vehicle 10000, thereby improving the maneuverability and safety of the vehicle 10000.

[0097] In some embodiments, as shown in conjunction with Figures 6, 7, and 12, the mounting base 110 includes a limiting boss 1142, and the diffuser 100 further includes a fixing base 170. The pivot shaft 161 is rotatably disposed on the fixing base 170, and the fixing base 170 is fixed to the limiting boss 1142. Thus, the pivot shaft 161 is rotatably disposed on the limiting boss 1142 of the mounting base 110. While the mounting base 110 supports the pivot shaft 161, the difficulty of fixing the pivot shaft 161 is reduced, the working performance of the pivot shaft 161 is ensured, and the driving assembly 150 can effectively drive the spoiler 120 to rotate.

[0098] In some embodiments, in combination with Figures 7, 10 and 12, a third mounting hole 11421 is formed on the limiting boss 1142, and the fixing seat 170 is provided with a matching hole matching the third mounting hole 11421. The diffuser 100 also includes a pin shaft 190, which passes through the matching hole on the fixing seat 170 and is positioned and matched in the third mounting hole 11421 to fix the fixing seat 170 to the limiting boss 1142 and reduce the difficulty of fixing the fixing seat 170.

[0099] Optionally, as shown in Figure 10, the fixing seat 170 is fixed to the limiting boss 1142 through multiple pins 190 to improve the fixing strength between the fixing seat 170 and the limiting boss 1142, thereby improving the position stability of the fixing seat 170, which is conducive to ensuring the working performance of the pivot shaft 161.

[0100] In some embodiments, as shown in Figure 10, a through hole 171 is provided on the fixing seat 170, and a bushing 172 is provided in the through hole 171. The pivot shaft 161 can be rotatably passed through the through hole 171 to enable the pivot shaft 161 to be rotatably set on the fixing seat 170. At the same time, the bushing 172 can also prevent the pivot shaft 161 from generating noise and metal wear during movement, thereby extending the service life of the pivot shaft 161 and reducing the rotation noise of the pivot shaft 161.

[0101] In some embodiments, as shown in conjunction with Figures 7, 8, and 12, the mounting base 110 further includes a first stopper 1161 and a second stopper 1162. The first stopper 1161 and the second stopper 1162 are spaced apart from each other on the mounting base 110. The first stopper 1161 and the second stopper 1162 are adapted to respectively contact the linkage assembly 160 to limit the rotation angle of the spoiler 120. This prevents the spoiler 120 from angular deviation during opening and closing to a certain extent, thereby ensuring that the spoiler 120 can be opened or closed smoothly and accurately to a certain angle during driving, thereby enhancing the spoiler 120's spoiling effect and improving the maneuverability and safety of the vehicle 10000.

[0102] In some embodiments, the first limiter 1161 is used to limit the maximum opening angle of the spoiler 120, and the second limiter 1162 is used to limit the minimum opening angle of the spoiler 120, thereby achieving the purpose of limiting the rotation angle of the spoiler 120 by utilizing the first limiter 1161 and the second limiter 1162.

[0103] It should be noted that when the opening angle of the spoiler 120 is large, the passability of the vehicle 10000 will be affected, and when the opening angle of the spoiler 120 is small, the wind resistance will increase.

[0104] Therefore, the present application limits the angle of the spoiler 120 during rotational movement by setting a first limiter 1161 and a second limiter 1162 to ensure that the spoiler 120 can smoothly and accurately control the opening or closing angle during driving, prevent the spoiler 120 from generating angular deviation during the rotational opening and closing movement, ensure the spoiler 120's spoiling effect, and thereby improve the controllability and safety of the vehicle 10000.

[0105] In some embodiments, the first limit member 1161, the second limit member 1162 and the mounting base 110 are integrally formed. In this way, while reducing the difficulty of molding the first limit member 1161 and the second limit member 1162, the connection between the first limit member 1161, the second limit member 1162 and the mounting base 110 can also be omitted to reduce the difficulty of fixing the first limit member 1161 and the second limit member 1162. At the same time, it is also convenient to improve the positional stability of the first limit member 1161 and the second limit member 1162 to ensure the limiting function of the first limit member 1161 and the second limit member 1162, thereby avoiding angular deviation of the spoiler 120 during the opening and closing movement, so as to improve the working performance of the spoiler 120.

[0106] In some embodiments, the mounting base 110 is provided with a guide path for guiding the direction of the wire 151 of the driving assembly 150. This means that the driving assembly 150 has a wire 151 (the specific structure of the wire 151 can be seen in FIG12 ), and the mounting base 110 is provided with a guide path for guiding the direction of the wire 151, thereby reducing the difficulty of routing the wire 151 and ensuring that the wire 151 can be effectively electrically connected to the driving assembly 150, thereby ensuring the working performance of the driving assembly 150.

[0107] At the same time, by setting the guide path, the space occupied by the wire 151 can be saved and the assembly efficiency of the wire 151 can be improved.

[0108] In some embodiments, as shown in FIG6 , FIG7 , and FIG12 , the mounting base 110 is provided with a plurality of fixing holes 117 , each of which is provided with a wire clamping ring 180 . The wire clamping rings 180 define a guide path to guide the direction of the wire 151 , thereby reducing the difficulty of routing the wire 151 .

[0109] Through the above-mentioned arrangement, during the specific routing of the wire 151, the wire 151 can be first extended according to the arrangement direction of the multiple fixing holes 117, and then the wire clamping ring 180 can be installed on the fixing hole 117 to achieve the purpose of fixing the wire 151 by using the wire clamping ring 180, thereby improving the position stability of the wire 151, thereby achieving the purpose of guiding the direction of the wire 151 and reducing the difficulty of routing the wire 151.

[0110] In some embodiments, as shown in conjunction with Figures 4 and 5 , the mounting base 110 further includes an intermediate positioning member 118.
