[0081] The mounting base 110 of the embodiment of the present utility model is described below with reference to the accompanying drawings.

[0082] Among them, combined Figure 3 , Figure 4 and Figure 6 As shown, the front side of the mounting seat 110 is provided with a first mounting portion 111 for fixing to the vehicle body, and the rear side of the mounting seat 110 is provided with a second mounting portion 112 and a third mounting portion 113, the second mounting portion 112 is used to install the rear bumper 200, and the third mounting portion 113 is used to install the spoiler 120. Here, it means that the front side of the mounting seat 110 is provided with a first mounting portion 111 for fixing the mounting seat 110 to the vehicle body, and the rear side of the mounting seat 110 is provided with a second mounting portion 112 for fixing the rear bumper 200 to the mounting seat 110 and a third mounting portion 113 for fixing the spoiler 120 to the mounting seat 110.

[0083] It should be noted that, in the prior art, the mounting base 110 of the diffuser 100 is usually fixed at the rear bumper 200. Since the rear bumper 200 is usually made of plastic, the weight of the rear bumper 200 will be increased, making the rear bumper 200 at risk of sinking, and fatigue damage will occur after a period of time, affecting the quality of the vehicle and even endangering the safety of the driver and passengers.

[0084] In order to solve the above problems, the present application provides a first mounting portion 111 for fixing the mounting seat 110 to the vehicle body on the front side of the mounting seat 110, 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 used 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 increasing the weight of the rear bumper 200 due to the provision of the mounting seat 110, which makes the rear bumper 200 have the risk of sinking, thereby ensuring the working performance of the rear bumper 200 and extending the service life of the rear bumper 200.

[0085] 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, and 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 on the vehicle body, so as to fix the rear bumper 200 with the vehicle body, 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.

[0086] That is to say, the body and rear bumper 200 of the vehicle 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. In this way, while the diffuser 100 is supported by the body, the rear bumper 200 can be directly used to shield the mounting point between the mounting seat 110 and the body, eliminating the need for a beautification panel. While ensuring the appearance quality of the vehicle, the structure of the vehicle can be simplified, the manufacturing cost of the vehicle can be reduced, and the weight of the vehicle can be reduced, thereby achieving lightweighting of the vehicle.

[0087] In addition, by providing a third mounting portion 113 on the rear side of the mounting seat 110, the spoiler 120 can be provided on the mounting seat 110. Since the mounting seat 110 is stably connected to the vehicle body, the mounting seat 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 run 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, thereby ensuring the working performance of the diffuser 100 and facilitating the use of the diffuser 100 to improve the handling stability of the vehicle.

[0088] It can be seen from the above structure that the mounting seat 110 of the embodiment of the utility model 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 avoiding sinking and damage of 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.

[0089] 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 arranged 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, thereby eliminating the need for a beautification panel. While ensuring the appearance quality of the vehicle, the structure of the vehicle can be simplified and the weight and manufacturing cost of the vehicle can be reduced.

[0090] By providing the third mounting portion 113 at the rear side of the mounting seat 110, the spoiler 120 can be matched with the mounting seat 110, so that the spoiler 120 can be used to improve the air flow efficiency at the bottom of the vehicle, ensure the working performance of the diffuser 100, and thus ensure the handling stability of the vehicle.

[0091] It can be understood that, compared with the prior art, the present application sets the mounting base 110 of the diffuser 100 between the vehicle body and the rear bumper 200. In this way, while the diffuser 100 and the rear bumper 200 are supported by the vehicle body, the rear bumper 200 can also be used to shield the mounting point between the mounting base 110 and the vehicle body. While ensuring the appearance quality of the vehicle, it can also simplify the vehicle structure and reduce the weight and manufacturing cost of the vehicle.

[0092] In some embodiments, in combination Figure 1 and Figure 2 As shown, the spoiler 120 is rotatably matched with the third mounting portion 113 to realize the rotation of the spoiler 120 on the mounting seat 110, thereby facilitating the control of the rotation of the spoiler 120, realizing the use of the spoiler 120 to improve the air flow efficiency at the bottom of the vehicle, ensuring the working performance of the diffuser 100, and facilitating the use of the diffuser 100 to improve the handling stability of the vehicle.

[0093] In some embodiments, in combination Figure 6 and Figure 7 As shown, the second mounting portion 112 includes a first boss 1121 protruding from the mounting seat 110, the first boss 1121 is provided with a first mounting hole 1122, and the rear bumper 200 is adapted to be fixed to the first boss 1121. The rear bumper 200 is connected with the mounting seat 110 in a coordinated manner, so that the rear bumper 200 is supported by the vehicle body, the position stability of the rear bumper 200 is improved, and the rear bumper 200 is prevented from being loose, making abnormal noises, and sinking to a certain extent during driving, thereby ensuring the working performance of the rear bumper 200.

[0094] In some embodiments, in combination Figure 6 and Figure 7As shown, the second mounting portion 112 includes a plurality of first bosses 1121, and the plurality of first bosses 1121 are spaced apart 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.

[0095] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0096] In some embodiments, in combination Figure 6 , Figure 7 and Fig. 9 As shown, 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 , so as to fix the rear bumper 200 to the mounting base 110 and improve the position stability of the rear bumper 200 .

[0097] The fastener 141 mentioned here may be a fastening screw.

[0098] 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 be reduced, which facilitates processing and reduces the difficulty of connection.

[0099] It should also be noted that the above-mentioned arrangement can also realize a fixed and detachable connection between the rear bumper 200 and the mounting seat 110. Compared with the prior art in which the rear bumper 200 and the mounting seat 110 are connected by bonding, clamping or welding, the connection strength between the rear bumper 200 and the mounting seat 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.

[0100] In some embodiments, in combination Figure 6 and Figure 7As shown, the second mounting portion 112 further includes a mounting surface 1123 located below the first boss 1121, and the mounting surface 1123 is provided with a second mounting hole 1124, and the rear bumper 200 is adapted to be fixed to the mounting surface 1123 by abutment. This increases the contact area between the rear bumper 200 and the mounting seat 110, thereby facilitating the stable mounting of the rear bumper 200 on the mounting seat 110, achieving the support of the rear bumper 200 by the vehicle body, improving the position stability of the rear bumper 200, and to a certain extent preventing the rear bumper 200 from being loose, making abnormal noises, and sinking during driving, thereby ensuring the working performance of the rear bumper 200.

[0101] The schematic diagram after the rear bumper 200 and the mounting base 110 are assembled can be seen in FIG. Fig.11 .

[0102] In some embodiments, in combination Figure 6 and Figure 7 As shown, the mounting seat 110 is provided with a second boss 1141 and / or a flange 115 to define a mounting surface 1123. Here, it means that the second boss 1141 can be provided on the mounting seat 110 to define the mounting surface 1123; or, the flange 115 can be provided on the mounting seat 110 to define the mounting surface 1123; or, the second boss 1141 and the flange 115 can be provided on the mounting seat 110 to define the mounting surface 1123, thereby reducing the difficulty of forming the mounting surface 1123, facilitating the use of the mounting surface 1123 to increase the contact area between the rear bumper 200 and the mounting seat 110, so that the rear bumper 200 can be stably mounted on the mounting seat 110.

[0103] In some embodiments, Figure 7 As shown, part of the mounting surface 1123 is defined by the flange 115 provided on the mounting seat 110 , and another part of the mounting surface 1123 is defined by the second boss 1141 provided on the mounting seat 110 .

[0104] It should be noted that by using the second boss 1141 to define the mounting surface 1123, it is also helpful 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, reduce the welding nut positioning tooling process, facilitate processing, and reduce the difficulty of connection.

[0105] 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 convenient to tap threads on the mounting surface 1123 .

[0106] In some embodiments, in combination Figure 2 , Figure 6 and Figure 7As shown, 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 have the same mounting surface 1123, and the spoiler 120 is fixed to the mounting seat 110 by passing the first fastener 140 through the spoiler 120 and fixing it to the second mounting hole 1124, so as to achieve fixing the spoiler 120 on the mounting seat 110, and at the same time, because the spoiler 120 is movable relative to the first fastener 140, the spoiler 120 can rotate relative to the mounting seat 110, so as to ensure the working performance of the spoiler 120.

[0107] At the same time, because the rear bumper 200 is arranged between the spoiler 120 and the mounting seat 110, when the first fastener 140 passes through the spoiler 120 and is fixed to the second mounting hole 1124, the rear bumper 200 can be fixedly connected to the mounting seat 110 through the first fastener 140, so that the spoiler 120 and the rear bumper 200 are installed on the mounting seat 110 together through the first fastener 140, and the rear bumper 200 is clamped between the spoiler 120 and the mounting seat 110. This assembly method is not only simple and convenient to assemble but also has a reliable connection, which enhances the assembly accuracy and stability of the mounting seat 110, the spoiler 120 and the rear bumper 200, on the one hand, ensures that the spoiler 120 can run smoothly and not fall off under complex working conditions, and on the other hand, it can also increase the strength of the rear bumper 200, effectively prevent the rear bumper 200 from becoming loose, making abnormal noises, and sinking during driving, thereby ensuring the working performance of the rear bumper 200.

[0108] 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.

[0109] It is also worth noting that the present application uses the third mounting portion 113 and the second mounting portion 112 to share the mounting surface 1123, 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.

[0110] 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, while also ensuring the connection strength between 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.

[0111] In some embodiments, in combination Figure 4 and Figure 5 As shown, 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, and the longitudinal mounting portion 1112 is provided with a longitudinal mounting hole. In this way, the mounting seat 110 can be mounted on the vehicle body using the transverse mounting hole and the longitudinal mounting hole respectively to achieve a fixed connection between the mounting seat 110 and the vehicle body, while reducing the difficulty of connecting the mounting seat 110 and the vehicle body, and can also ensure the connection quality of the mounting seat 110 and the vehicle body.

[0112] At the same time, by configuring 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.

[0113] In some embodiments, in combination Figure 4 and Figure 5 As shown, the transverse mounting portion 1111 and the longitudinal mounting portion 1112 are respectively formed as bosses protruding from the mounting seat 110.

[0116] 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, which facilitates the disassembly of the mounting base 110 and reduces the difficulty of maintaining the mounting base 110.

[0117] In some embodiments, Fig.12 As shown, the mounting seat 110 is further provided with a fixing position 1194 for fixing the driving assembly 150, and the driving assembly 150 is suitable for connecting with the spoiler 120 to drive the spoiler 120 to rotate. Here, the diffuser 100 includes the driving assembly 150 and the spoiler 120, and the driving assembly 150 is arranged on the mounting seat 110 through the fixing position 1194 and connected with the spoiler 120, so that the spoiler 120 can rotate relative to the mounting seat 110, so as to facilitate the use of the spoiler 120 to improve the flow efficiency of the air under the vehicle, thereby ensuring the handling stability of the vehicle.

[0118] In addition, by arranging the driving assembly 150 on the mounting seat 110 , the driving assembly 150 can also be supported by the mounting seat 110 to improve the position stability of the driving assembly 150 and ensure the working performance of the driving assembly 150 .

[0119] In some embodiments, the driving assembly 150 is a driving 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 and ensure the handling stability of the vehicle.

[0120] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, 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, so as to utilize the mounting base 110 to support the drive assembly 150, thereby improving the position stability of the drive assembly 150 and ensuring the working performance of the drive assembly 150.

[0121] 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.

[0122] In some embodiments, Figure 8 As shown, a plurality of limiting ribs 11941 are provided at the fixed 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 allowing the driving assembly 150 to operate smoothly.

[0123] Optionally, the thickness of the limiting rib 11941 ranges from 5 mm to 7 mm, so as to ensure that the limiting rib 11941 can effectively support the driving assembly 150 and improve the position stability of the driving assembly 150.

[0124] In a specific example, the thickness of the limiting rib 11941 is 5 mm, 5.5 mm, 6 mm, 6.5 mm or 7 mm, etc.

[0125] In some embodiments, Fig.12 As shown, the driving assembly 150 is connected to the spoiler 120 through the connecting rod assembly 160, and the connecting rod assembly 160 includes a pivot shaft 161. The mounting seat 110 is provided with a limiting boss 1142, and the pivot shaft 161 is rotatably arranged on the limiting boss 1142. In other words, the driving assembly 150 is connected to the spoiler 120 through the pivot shaft 161 to ensure that the driving assembly 150 can effectively drive the spoiler 120 to rotate, reduce the difficulty of rotating the spoiler 120, and ensure the spoiler effect or other functional properties of the spoiler 120, so as to facilitate the use of the spoiler 120 to improve the flow efficiency of the air under the vehicle, and improve the handling and safety of the vehicle.

[0126] In some embodiments, in combination Figure 6 , Figure 7 and Fig.12 As shown, the mounting seat 110 includes a limiting boss 1142, and the diffuser 100 also includes a fixing seat 170. The pivot shaft 161 is rotatably disposed on the fixing seat 170, and the fixing seat 170 is fixed to the limiting boss 1142. Thus, the pivot shaft 161 is rotatably disposed on the limiting boss 1142 of the mounting seat 110, and while the mounting seat 110 is used to support the pivot shaft 161, the difficulty of fixing the pivot shaft 161 can be reduced, the working performance of the pivot shaft 161 is guaranteed, and the driving assembly 150 can be used to effectively drive the spoiler 120 to rotate.

[0127] In some embodiments, in combination Figure 7 , Fig.10 and Fig.12 As shown, a third mounting hole 11421 is formed on the limiting boss 1142, and the fixing seat 170 is provided with a matching hole matching with the third mounting hole 11421. The diffuser 100 also includes a pin shaft 190, and the pin shaft 190 passes through the matching hole on the fixing seat 170 and is positioned and matched in the third mounting hole 11421, so as to fix the fixing seat 170 to the limiting boss 1142 and reduce the difficulty of fixing the fixing seat 170.

[0128] Alternatively, if Fig.10 As shown, the fixing seat 170 is fixed to the limiting boss 1142 by a plurality of 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 beneficial to ensuring the working performance of the pivot shaft 161 .

[0129] In some embodiments, Fig.10 As shown, 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 rotatably pass through the through hole 171 to realize that the pivot shaft 161 can be rotatably arranged 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.

[0130] In some embodiments, in combination Figure 7 , Figure 8 and Fig.12 As shown, the mounting seat 110 further includes a first stopper 1161 and a second stopper 1162, which are spaced apart from each other on the mounting seat 110, and are adapted to contact the connecting rod assembly 160 respectively to limit the rotation angle of the spoiler 120. This prevents the spoiler 120 from generating an angle deviation during the opening and closing movement to a certain extent, thereby ensuring that the spoiler 120 can be opened or closed at a certain angle smoothly and accurately during driving, thereby improving the spoiler effect of the spoiler 120 and improving the handling and safety of the vehicle.

[0131] 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 goal of limiting the rotation angle of the spoiler 120 by utilizing the first limiter 1161 and the second limiter 1162.

[0132] It should be noted that when the opening angle of the spoiler 120 is large, the vehicle's passability will be affected, and when the opening angle of the spoiler 120 is small, the wind resistance will increase.

[0133] Therefore, the present application sets a first limit member 1161 and a second limit member 1162 to limit the angle of the spoiler 120 during rotational movement, so as to ensure that the spoiler 120 can smoothly and accurately control the opening or closing angle during driving, prevent the spoiler 120 from generating an angle deviation during the rotational opening and closing movement, ensure the spoiler effect of the spoiler 120, and thus improve the vehicle's handling and safety.

[0134] In some embodiments, the first limit piece 1161, the second limit piece 1162 are integrally formed with the mounting base 110. In this way, while reducing the difficulty of molding the first limit piece 1161 and the second limit piece 1162, the connection between the first limit piece 1161, the second limit piece 1162 and the mounting base 110 can be omitted to reduce the difficulty of fixing the first limit piece 1161 and the second limit piece 1162. At the same time, it is also convenient to improve the position stability of the first limit piece 1161 and the second limit piece 1162 to ensure the limiting function of the first limit piece 1161 and the second limit piece 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.

[0136] 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.

[0137] In some embodiments, in combination Figure 6 , Figure 7 and Fig.12 As shown, the mounting seat 110 is provided with a plurality of fixing holes 117 , each fixing hole 117 is provided with a wire clamping ring 180 , and the plurality of wire clamping rings 180 define a guiding path to guide the direction of the wire 151 , thereby reducing the difficulty of routing the wire 151 .

[0138] Through the above arrangement, during the specific routing of the wire 151, the wire 151 can be first extended according to the arrangement direction of the plurality of 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 routing difficulty of the wire 151.
