Description

Technical Field

[0001] This disclosure relates to the field of vehicle manufacturing technology, and more particularly to a diffuser assembly and a vehicle. Background Technology

[0002] In related technologies, the diffuser and fog lights of vehicles are separate units, requiring individual assembly operations, which increases the number of steps in the overall vehicle assembly process and affects the overall vehicle assembly efficiency. Utility Model Content

[0003] The purpose of this disclosure is to provide a diffuser assembly and a vehicle to solve the problems in the aforementioned related technologies.

[0004] To achieve the above objectives, one aspect of this disclosure provides a diffuser assembly comprising: A diffuser body, wherein a receiving portion is provided inside the diffuser body, and an opening is provided in the diffuser body, the opening being in communication with the receiving portion; A fog light is disposed within the receiving portion and connected to the diffuser body. The irradiation end of the fog light is disposed at the opening to irradiate light outside the receiving portion.

[0005] In the above technical solution, by providing a receiving portion within the diffuser body to accommodate the fog lights, the fog lights can be connected to the diffuser body, thus achieving an integrated design of the diffuser body and fog lights. The diffuser body and fog lights can be pre-assembled together, forming a single integrated structure. Furthermore, the fog lights are designed within the receiving portion, allowing the diffuser body to enclose them in a wraparound structure. The fog lights do not interfere with the normal function of the diffuser body, and the openings on the diffuser body allow the fog lights to project light without affecting their functionality. This diffuser assembly allows for simultaneous installation of the diffuser body and fog lights in a single assembly, reducing vehicle assembly steps and improving overall assembly efficiency.

[0006] In some possible implementations, the diffuser body includes a bracket and a panel, the panel and the bracket being respectively used for connection to a vehicle body, the bracket being connected to the panel, a portion of the bracket being spaced apart from the panel to form the receiving portion, the opening being located on the panel, and the fog light being connected to the panel.

[0007] This design facilitates the formation of a receiving section to accommodate the fog lights.

[0008] In some possible implementations, in the longitudinal direction of the vehicle, a first gap space is provided between the end of the fog light facing away from the panel and the bracket, the first gap space being used to accommodate the fog light in the event of a vehicle collision.

[0009] This design allows the fog lights to move in the forward and backward direction of the vehicle during a collision, providing cushioning and creating a crumple zone to absorb energy.

[0010] In some possible implementations, the fog light includes a mounting bracket and a lamp body. The mounting bracket is connected to the panel, and the lamp body is connected to the mounting bracket via a mounting part. In the longitudinal direction of the vehicle, a second gap space is provided between the mounting part and the bracket, the second gap space being used to accommodate the mounting part in the event of a vehicle collision.

[0011] This design enhances the installation strength and stability of the lamp body. In the event of a vehicle collision, the mounting section can move in the forward and backward directions to provide cushioning. It also provides crumple zone to ensure the connection between the lamp body and the mounting bracket, preventing it from detaching upon impact.

[0012] In some possible implementations, the bracket includes a first frame portion and a second frame portion, wherein the first frame portion is closer to the fog light than the second frame portion, and the structural strength of the first frame portion is greater than that of the second frame portion.

[0013] This design enhances the protection of the fog lights, thereby improving their impact resistance.

[0014] In some possible implementations, the panel includes a first plate portion and a second plate portion, the first plate portion being closer to the fog light than the second plate portion, and the structural strength of the first plate portion being greater than the structural strength of the second plate portion.

[0015] This design enhances the protection of the fog lights, thereby improving their impact resistance.

[0016] In some possible implementations, the diffuser body further includes a driver, a deflector blade, and a transmission component. The deflector blade is disposed on the side of the panel opposite to the support and is rotatably connected to the panel. The driver is connected to the support, and the transmission component is connected to the output end of the driver and the deflector blade, respectively. The driver is used to drive the deflector blade to rotate.

[0017] This configuration allows the deflector blades to rotate, enabling them to perform their deflection function in different scenarios.

[0018] In some possible implementations, the bracket has a reinforcing part and a limiting part on the side facing away from the panel. The reinforcing part is close to the fog light, and the limiting part is connected to the driver and is used to restrict the movement of the driver.

[0019] This design strengthens the structure at the connection point between the fog light and the bracket, while also ensuring the stability of the driver installation.

[0020] In some possible implementations, the transmission component includes a crossbar and a linkage assembly, the crossbar being connected to the output of the driver, the linkage assembly being connected to the end of the crossbar, the crossbar extending along the width direction of the vehicle to allow the linkage assembly to avoid the first gap space, and the linkage assembly being connected to the spoiler blade. The bracket and the panel are provided with through holes for the connecting rod assembly to pass through and connect with the spoiler blades.

[0021] This configuration ensures that the fog lights can move freely during a collision, thus meeting the collision requirements.

[0022] A second aspect of this disclosure also provides a vehicle including the aforementioned diffuser assembly.

[0023] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0032] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0033] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0035] A diffuser is an aerodynamic component that, depending on the vehicle's operating conditions, turbulents the airflow to improve vehicle performance. Fog lights are components that enhance vehicle visibility in rainy or foggy weather.

[0036] In related technologies, the diffuser and fog lights of a vehicle are separate components, requiring individual assembly operations. This increases the number of steps in the overall vehicle assembly process and affects the overall assembly efficiency. In other words, the diffuser needs to be assembled once, and then the fog lights need to be assembled once, requiring two assembly operations during the overall vehicle assembly.

[0037] Therefore, such as Figures 1-7 As shown, one aspect of this disclosure provides a diffuser assembly, including a diffuser body 1 and a fog light 2.

[0038] The diffuser body 1 has a receiving portion 12 inside, and the diffuser body 1 has an opening 11 that communicates with the receiving portion 12. The fog light 2 is disposed inside the receiving portion 12 and connected to the diffuser body 1. The irradiation end of the fog light 2 is disposed in the opening 11 so as to irradiate light outside the receiving portion 12.

[0039] In the above technical solution, by providing a receiving portion 12 within the diffuser body 1, the receiving portion 12 can accommodate the fog light 2, allowing the fog light 2 to be connected to the diffuser body 1. This achieves an integrated design of the diffuser body 1 and the fog light 2, enabling pre-assembly of the two into a single integrated structure. Furthermore, the fog light 2's design within the receiving portion 12 allows the diffuser body 1 to enclose the fog light 2 in a wraparound structure, ensuring the fog light 2 does not interfere with the normal function of the diffuser body 1. The opening 11 on the diffuser body 1 also allows the fog light 2 to project light without affecting its function. This diffuser assembly allows for simultaneous installation of the diffuser body 1 and fog light 2 in a single assembly, reducing vehicle assembly steps and improving overall vehicle assembly efficiency.

[0040] Optionally, in one embodiment of this disclosure, the diffuser body 1 includes a bracket 13 and a panel 14. The panel 14 and the bracket 13 are respectively used to connect to the vehicle body. The bracket 13 is connected to the panel 14. A portion of the bracket 13 is spaced apart from the panel 14 to form a receiving portion 12. An opening 11 is located on the panel 14. A fog light 2 is connected to the panel 14.

[0041] The panel 14 is an exterior trim panel that ensures aesthetics, while the bracket 13 is a supporting structure that supports the panel 14. The bracket 13 is located inside the panel 14, meaning that one side of the panel 14 faces outwards and the other side faces inwards, with the bracket 13 connected to the inward-facing side of the panel 14. The bracket 13 is used to connect to the vehicle's anti-collision beam, while the panel 14 is used to connect to the vehicle's bumper. The panel 14 is larger than the bracket 13, thus concealing the bracket 13 from being exposed.

[0042] In some examples, the edge of the bracket 13 can be connected to the inward-facing side of the panel 14, and the middle portion of the bracket 13 is spaced apart from the panel 14, thereby forming a receiving portion 12 between the bracket 13 and the panel 14 for accommodating the fog light 2. It is understood that the middle portion of the bracket 13 can be configured to bulge outward in a direction away from the panel 14, thereby forming a spaced-apart arrangement and the receiving portion 12. In some examples, the bracket 13 may include a first plate and a second plate, with one side of the first plate and one side of the second plate connected to each other. The first plate and the second plate are angled together. The side of the first plate away from the second plate may have a first flange, and the side of the second plate away from the first plate may have a second flange. Both the first flange and the second flange can be connected to the panel 14. The first plate and the second plate are face-to-face with the panel 14 and spaced apart to form the receiving portion 12. In other examples, the bracket 13 can be face-to-face connected to the inward-facing side of the panel 14, and the side of the bracket 13 facing the panel 14 may have an inner groove, which is the receiving portion 12.

[0043] The fog light 2 is connected to the panel 14, so that a part of the fog light 2 can be set in the opening 11. Thus, the illuminating end of the fog light 2 can be exposed outside through the opening 11, so that the light generated by the fog light 2 can shine outward and ensure the function of the fog light 2.

[0044] Optionally, in another embodiment of this disclosure, the diffuser body 1 includes an integrally formed structural component, and a groove is provided on the inner side of the diffuser body 1. The groove is a receiving part 12, and an opening 11 is provided at the bottom of the groove, so that the fog lamp 2 is placed in the groove and partially placed in the opening 11.

[0045] Optionally, in one embodiment of this disclosure, a first gap space 15 is provided between the end of the fog light 2 facing away from the panel 14 and the bracket 13 in the longitudinal direction of the vehicle. The first gap space 15 is used to accommodate the fog light 2 in the event of a vehicle collision. With this arrangement, the fog light 2 can move in the longitudinal direction of the vehicle in the event of a collision, thereby achieving buffering and having a crumple zone to absorb energy.

[0046] The first gap space 15 between the fog light 2 and the bracket 13 serves as a movable buffer space, preventing the fog light 2 from directly impacting the bracket 13 during a vehicle collision. The impact forces would damage the fog light 2. The first gap space 15 accommodates the fog light 2 during a collision, providing a buffer and allowing the fog light 2 to move, thus reducing collision damage and meeting the relevant collision performance requirements. In some examples, the diffuser assembly is located at the rear of the vehicle, requiring the fog light 2 to meet rear-end collision performance requirements. In this case, the first gap space 15 is located in front of the fog light 2 in the longitudinal direction.

[0047] Optionally, in one embodiment of this disclosure, the fog light 2 includes a mounting bracket 21 and a lamp body 22. The mounting bracket 21 is connected to the panel 14, and the lamp body 22 is connected to the mounting bracket 21 via a mounting part. In the longitudinal direction of the vehicle, a second gap space 23 is provided between the mounting part and the bracket 13. The second gap space 23 is used to accommodate the mounting part in the event of a vehicle collision. The mounting bracket 21 provided can improve the installation strength of the lamp body 22 and ensure installation stability.

[0048] One side of the mounting bracket 21 faces the panel 14, enabling a surface-to-surface connection with the panel 14, thereby increasing the connection area and thus improving the connection strength. The lamp body 22 is connected to the side of the mounting bracket 21 that faces away from the panel 14. In some examples, the mounting bracket 21 is welded to the panel 14, and the mounting part can be a screw, so that the lamp body 22 and the mounting bracket 21 can be installed with screws.

[0049] The second gap space 23 allows the mounting part to move in the longitudinal direction of the vehicle during a collision, providing cushioning and crumple zone to maintain the connection between the lamp body 22 and the mounting bracket 21, preventing it from detaching during a collision. It can be understood that the second gap space 23 also acts as a buffer space, preventing the mounting part from directly impacting the bracket 13 during a collision. The forward and backward forces of the collision could cause the connection to fail, leading to the lamp body 22 detaching, thus meeting the relevant collision performance requirements of the fog light 2. The second gap space 23 accommodates the mounting part during a collision, providing a buffer space for it to move. In some examples, the diffuser assembly is located at the rear of the vehicle, thus the fog light 2 needs to meet rear collision performance requirements. In this case, the second gap space 23 is located in front of the mounting part in the longitudinal direction of the vehicle.

[0050] Optionally, in one embodiment of this disclosure, the bracket 13 includes a first frame portion 131 and a second frame portion 132. The first frame portion 131 is closer to the fog light 2 than the second frame portion 132, and the structural strength of the first frame portion 131 is greater than that of the second frame portion 132. By increasing the structural strength of the first frame portion 131, the protective effect on the fog light 2 is improved, thereby enhancing the collision performance of the fog light 2 and meeting collision requirements. It is understood that in the event of a vehicle collision, the first frame portion 131 can withstand more collision force and reduce deformation, thereby reducing the collision energy borne by the fog light 2.

[0051] In some examples, the structural strength of the first frame portion 131 can be increased by setting its thickness to be greater than that of the second frame portion 132. In other examples, the structural strength of the first frame portion 131 can be increased by using different materials for the first frame portion 131 and the second frame portion 132, with the material of the first frame portion 131 having a greater structural strength than that of the second frame portion 132. Alternatively, structural ribs extending along the longitudinal direction of the vehicle can also be provided in the first frame portion 131 to increase its structural strength.

[0052] Optionally, in one embodiment of this disclosure, the panel 14 includes a first plate portion 141 and a second plate portion 142. The first plate portion 141 is closer to the fog lamp 2 than the second plate portion 142, and the structural strength of the first plate portion 141 is greater than that of the second plate portion 142. By increasing the structural strength of the first plate portion 141, the protective effect on the fog lamp 2 is improved, thereby improving the collision performance of the fog lamp 2 and meeting collision requirements. It is understood that in the event of a vehicle collision, the first plate portion 141 can withstand more collision force and reduce deformation, thereby reducing the collision energy borne by the fog lamp 2.

[0053] In some examples, the structural strength of the first plate portion 141 can be increased by setting its thickness to be greater than that of the second plate portion 142. In other examples, the structural strength of the first plate portion 141 can be increased by using different materials for the first plate portion 141 and the second plate portion 142, with the structural strength of the material of the first plate portion 141 being greater than that of the material of the second plate portion 142. It should be noted that the structural strength of the first frame portion 131 and / or the first plate portion 141 can be increased as needed. Alternatively, structural ribs extending along the front-rear direction of the vehicle can also be provided in the first plate portion 141 to increase its structural strength.

[0054] Optionally, in one embodiment of this disclosure, the diffuser body 1 further includes deflector blades 17. The deflector blades 17 are disposed on the side of the panel 14 facing away from the bracket 13 and connected to the panel 14. The deflector blades 17 enable airflow turbulence, thereby altering the airflow state to meet the vehicle's driving requirements. It is understood that the deflector blades 17 are disposed on the outward-facing side of the panel 14, meaning they are outside the vehicle. Therefore, during vehicle operation, they can turbulentize the airflow around the vehicle, changing the airflow state. The deflector blades 17 extend along the longitudinal direction of the vehicle.

[0055] Optionally, in one embodiment of this disclosure, the diffuser body 1 further includes a driver 16 and a transmission component 18. The deflector blades 17 are rotatably connected to the panel 14. The driver 16 is connected to the bracket 13. The transmission component 18 is connected to the output end of the driver 16 and the deflector blades 17, respectively. The driver 16 drives the deflector blades 17 to rotate. Through the driver 16 and transmission component 18, the deflector blades 17 can be driven to rotate, allowing them to fulfill their deflection function in different scenarios. It is understood that the driver 16 transmits kinetic energy to the deflector blades 17 via the transmission component 18. Due to the rotatable design of the deflector blades 17, they can rotate, thereby changing their angle and altering their effect on airflow. For example, the deflection function of the deflector blades 17 can be turned on or off.

[0056] When the vehicle reaches a certain speed, the spoiler blades 17 open and adjust to a specific angle, shifting the vacuum turbulence area at the rear of the vehicle flow backward, reducing wind resistance and improving the vehicle's range. After the vehicle speed increases to a certain value, the spoiler blades 17 close, thereby increasing the airflow velocity under the vehicle, decreasing air pressure, reducing lift, controlling vehicle buoyancy, ensuring sufficient tire traction, allowing the vehicle to stay close to the road, and improving driving stability. Additionally, under static or specified conditions, the spoiler blades 17 can be manually opened to enhance the vehicle's appearance. It should be noted that the actuator 16 can be electrically connected to the vehicle's control unit, allowing operation via the vehicle's central control system to open or close the actuator 16, and adjust the opening or closing of the spoiler blades 17, as well as their angle. The vehicle's control unit can be programmed to automatically control and adjust the spoiler blades 17 according to vehicle speed.

[0057] Optionally, in one embodiment of this disclosure, the bracket 13 has a reinforcing portion 133 and a limiting portion 134 on the side facing away from the panel 14. The reinforcing portion 133 is close to the fog light 2, and the limiting portion 134 is connected to the driver 16, limiting the movement of the driver 16. The reinforcing portion 133 strengthens the structure of the bracket 13, particularly the area near the fog light 2, and also strengthens the connection between the driver 16 and the bracket 13, ensuring the stability of the driver 16's installation. The limiting portion 134 restricts the position of the driver 16, preventing movement and ensuring stable installation.

[0058] In some examples, the reinforcing part 133 can be configured as a reinforcing rib, which is formed on the surface of the bracket 13 and integrally formed with the bracket 13. There can be multiple reinforcing parts 133, spaced apart. The limiting part 134 can lock the driver 16 to restrict its movement. There can be multiple limiting parts 134, which are disposed on the four sides of the driver 16 to fix the driver 16 in place.

[0059] Optionally, in one embodiment of this disclosure, the transmission component 18 includes a crossbar 181 and a connecting rod assembly 182. The crossbar 181 is connected to the output end of the driver 16, and the connecting rod assembly 182 is connected to the end of the crossbar 181. The crossbar 181 extends along the width direction of the vehicle so that the connecting rod assembly 182 avoids the first gap space 15. The connecting rod assembly 182 is connected to the spoiler blade 17. By setting the crossbar 181, the first gap space 15 can be avoided, thus not affecting the movement of the fog light 2 in the event of a vehicle collision, ensuring the collision requirements of the fog light 2. The connecting rod assembly 182 can drive the spoiler blade 17 to rotate, satisfying the rotational freedom of the spoiler blade 17, so that the spoiler blade 17 rotates at a set angle. It can be understood that the connecting rod assembly 182 is set as a multi-stage linkage, which can drive the spoiler blade 17 to reciprocate to meet different angle requirements. In some examples, the linkage assembly 182 may be a four-bar linkage, and the number of linkage assemblies 182 may be two, with the two linkage assemblies 182 respectively disposed at the ends of the two ends of the crossbar 181.

[0060] In some examples, the actuator 16 can be a motor, with the crossbar 181 connected to the motor's output. The motor drives the crossbar 181 to rotate, and the connecting rod assembly 182 moves under the rotation of the crossbar 181, thereby causing the deflector blades 17 to rotate and change angle. In other examples, the actuator 16 can be an electric cylinder, which moves the crossbar 181 through telescopic movement, thereby moving the connecting rod assembly 182. In this example, the crossbar 181 is hinged to the output of the electric cylinder and the connecting rod assembly 182.

[0061] Optionally, in one embodiment of this disclosure, the bracket 13 and the panel 14 are provided with through holes for the connecting rod assembly 182 to pass through and connect with the spoiler blade 17. This arrangement facilitates the connection between the connecting rod assembly 182 and the spoiler blade 17, thereby driving the spoiler blade 17 to rotate.

[0062] A second aspect of this disclosure also provides a vehicle including the aforementioned diffuser assembly. This diffuser assembly integrates the diffuser body 1 and the fog lights 2 together, breaking conventional styling limitations and making the rear of the vehicle more novel in appearance. It ensures the functionality of the diffuser body 1, the fog lights 2, and also meets the collision performance requirements of the fog lights 2.

[0063] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0064] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0065] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
