[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0064] Reference Figures 1 to 4 As shown, this application provides a front bumper assembly 10, which includes: a stop device 100, an air intake grille 200, and a mounting frame 300.

[0065] The air intake grille 200 forms an air intake channel 200a, which allows airflow to enter the vehicle 1 from the front side, such as into the engine compartment to provide air cooling for the equipment in the engine compartment.

[0066] The stop device 100 has a stop state and a avoidance state; when the stop device 100 is in the stop state, the stop surface 111 closes the air intake passage 200a; when the stop device 100 is in the avoidance state, the stop surface 111 avoids the air intake passage 200a.

[0067] The mounting frame 300 is used to mount the stop device 100 to the air intake grille 200 or other parts of the front bumper assembly 10; the stop device 100 and the mounting frame 300 can be movably connected.

[0068] Reference Figures 1 to 8 As shown, the stop device 100 may include a stop member 110 for achieving a stop, and may also include a prime mover (such as an electric motor, not shown in the figure) for driving the stop member 110 and a transmission member 140 for achieving transmission between the prime mover and the stop member 110.

[0069] As a specific plan, refer to Figures 5 to 6As shown, the stop device 100 of this application mainly includes: a stop member 110 and a support member 120.

[0070] The stop member 110 is made of at least a first material; the support member 120 is made of at least a second material. The strength of the second material is greater than that of the first material; the stop member 110 is formed with a stop surface 111 that is adapted to the shape of the air intake grille 200; the support member 120 is disposed on the side of the stop member 110 away from the stop surface 111; the support member 120 and the stop member 110 are connected to support the stop member 110.

[0071] This approach allows the stop 110 to be made of a lower-strength material (such as plastic), resulting in a more rounded or complex shape that matches the overall shape of the vehicle 1 and reduces wind resistance. Conversely, the support 120 can be made of a higher-strength material (such as metal), ensuring that the stop 110 will not deform under the influence of airflow while providing sufficient structural strength during movement. In this way, by assigning different functions to the stop 110 and the support 120 and selecting different materials for them, both the shape and strength requirements of the stop device 100 are met.

[0072] Reference Figure 2 and Figure 3 As shown, as a specific embodiment, the stop surface 111 is constructed to have a curved surface; furthermore, the stop surface 111 is constructed to bend toward the side away from the support member 120. This allows the stop surface 111 to better fit the overall shape of the vehicle 1, thereby reducing wind resistance.

[0073] Reference Figures 5 to 10 As shown, the stop member 110 has a mounting groove 112 formed on the side away from the stop surface 111; the support member 120 is at least partially accommodated in the mounting groove 112; the mounting groove 112 has an opening facing the support member 120, through which the support member 120 can be directly installed into the mounting groove 112 of the stop member 110. This has the advantage of extending the stop member 110 inward from the stop surface 111 to a certain extent, thereby preventing the exposed support member 120 from affecting the shape of the vehicle 1.

[0074] Reference Figures 7 to 10 As shown, in some other embodiments of this application, the support member 120 is formed with ribs 123, and at least a portion of the ribs 123 protrudes toward the side away from the stop surface 111; this can enhance the torsional resistance of the support member 120.

[0075] Reference Figure 10As shown, a stepped structure 110a is formed at the intersection of the stop surface 111 and the groove wall 112a of the assembly groove 112 on the outer surface, which enables the stop 110 to be effectively limited to the air intake grille.

[0076] Reference Figure 6 As shown, in some embodiments of this application, only the stop member 110 and the support member 120 may be provided. In this case, the transmission member 140 may be connected to the support member 120 to realize transmission.

[0077] As a specific solution, the stop 110 and the support 120 can be fixedly connected, for example, by using fasteners 150 to connect them into a whole. Alternatively, they can be glued together. Considering the material and connection strength, fasteners 150 (threaded connection or riveting), welding, etc., are preferred. The stop 110 (e.g., injection molding) and the support 120 (casting or stamping) can be manufactured separately and then fixedly connected into a whole. Alternatively, the support 120 can be inserted into the stop 110 during manufacturing to form a single unit.

[0078] Reference Figures 7 to 10 As shown, in some other embodiments of this application, the stop device 100 further includes a reinforcing member 130. The reinforcing member 130 is used to strengthen the structural strength of certain predetermined areas of the stop device 100. The reinforcing member 130 can be made of a material similar to that of the support member 120, or it can be made of a different material. As an option, the reinforcing member 130 and the support member 120 can be made of the same type of material, such as both being made of metal. For example, the reinforcing member 130 can be made of aluminum alloy, while the support member 120 can be made of stainless steel. That is, they are made of the same type of material but not exactly the same.

[0079] Reference Figures 7 to 10 As shown, in some other embodiments of this application, the support member 120 is at least partially disposed between the stop member 110 and the reinforcing member 130, that is, the reinforcing member 130 is disposed on the side of the support member 120 away from the stop member 110, and is at least partially overlapped with the stop member 110 or the support member 120.

[0080] The reinforcing member 130 can provide localized reinforcement to the overall structure formed by the stop member 110 and the support member 120. Since the air intake channel 200a of the air intake grille 200 is often quite long and narrow, the two ends of the stop member 110 are far apart in its length direction, making it prone to deformation. To solve this problem, refer to... Figures 6 to 9 As shown, two reinforcing members 130 can be provided, with the two reinforcing members 130 positioned at two opposite ends of the stop device 100.

[0081] Reference Figures 7 to 10 As shown, in order to facilitate installation while ensuring structural strength, in some other embodiments of this application, the stop member 110 has a stop positioning structure 113 formed on the side away from the stop surface 111; the support member 120 has a support positioning structure 121 adapted to the stop positioning structure 113, specifically, the stop positioning structure 113 and the support positioning structure 121 form a positioning fit; the reinforcing member 130 has a reinforcing positioning structure 131 adapted to the stop positioning structure 113 or the support positioning structure 121.

[0082] In this way, during assembly, the relative positions of the stop 110 and the support 120 can be positioned by the cooperation of the stop positioning structure 113 and the support positioning structure 121. Similarly, when installing the reinforcement 130, the reinforcement positioning structure 131 can also cooperate with the stop positioning structure 113 or the support positioning structure 121 to position the reinforcement 130.

[0083] As a specific solution, the stop positioning structure 113 is constructed as a positioning block protruding to the side away from the stop surface 111; the support positioning structure 121 is constructed as a positioning hole; the positioning block and the positioning hole are positioned correspondingly, and positioning can be achieved by the positioning block being inserted into the positioning hole during assembly; the reinforcing positioning structure 131 can be constructed as a positioning block or a positioning hole; when the reinforcing positioning structure 131 is a positioning block, the support member 120 can form another positioning hole to cooperate with the positioning block of the reinforcing positioning structure 131 to achieve positioning, but the disadvantage of this is that the support member 120 having more positioning holes will reduce the structural strength.

[0084] As an alternative, refer to Figures 7 to 10 As shown, the stop positioning structure 113 is constructed as a positioning block protruding away from the stop surface 111; both the support positioning structure 121 and the reinforcing positioning structure 131 are constructed as positioning holes, and the positioning holes of the support positioning structure 121 and the reinforcing positioning structure 131 are aligned; after the positioning block of the stop positioning structure 113 is inserted into the positioning hole of the support positioning structure 121, it can also be inserted into the positioning hole of the reinforcing positioning structure 131. In this way, after the positioning of the stop member 110 and the support member 120 is completed, the reinforcing member 130 can still be positioned by relying on the original structure.

[0085] Reference Figures 7 to 10As shown, after the stop member 110, support member 120, and reinforcing member 130 are positioned, they can be fixedly connected by fasteners 150. That is, the stop device 100 also includes fasteners 150. The fasteners 150 can be used to fix the stop member 110 and support member 120; of course, the fasteners 150 can also fix any two or all of the stop member 110, support member 120, and reinforcing member 130.

[0086] To better achieve the connection and avoid affecting the appearance of the stop surface 111, in some embodiments of this application, reference is made to... Figures 7 to 10 As shown, the stop member 110 has a stop mounting structure 114 formed on the side away from the stop surface 111. Specifically, the stop mounting structure 114 is constructed as a mounting frame, and a threaded hole (not shown) is provided in the mounting frame. To accommodate the stop mounting structure 114, the support member 120 has a support mounting structure 122 that is fixedly connected to the stop mounting structure 114. Specifically, the support mounting structure 122 is constructed with a mounting groove (not shown) recessed towards the side away from the stop member 110, and a threaded hole (not shown) is provided at the bottom of the mounting groove. The mounting frame can be accommodated in the mounting groove, thereby aligning the threaded hole of the mounting frame and the mounting groove. The fastener 150 can pass through the stop mounting structure 114 and the support mounting structure 122 to fix the stop member 110 and the support member 120 together.

[0087] In some embodiments of this application, reference is made to Figures 7 to 10 As shown, the reinforcing member 130 has a reinforcing mounting structure 132 that is fixedly connected to the stop mounting structure 114 or the support mounting structure 122. Alternatively, the reinforcing mounting structure 132 can be constructed similarly to the support mounting structure 122, i.e., it can be configured with a mounting groove (not shown) recessed towards the side away from the stop member 110, and a threaded hole (not shown) at the bottom of the groove. The difference is that the mounting groove of the reinforcing mounting structure 132 accommodates the support mounting structure 122. In this case, the fastener 150 can pass through the stop mounting structure 114, the support mounting structure 122, and the reinforcing mounting structure 132 to form a fixed connection between the stop member 110, the support member 120, and the reinforcing member 130.

[0088] In addition to providing a fixed connection, the supporting mounting structure 122 and the reinforcing mounting structure 132 also serve to strengthen the structure.

[0089] As an optional solution, the stop mounting structure 114, the support mounting structure 122, and the reinforcing mounting structure 132 can also be fixedly connected by means of snap-fit ​​or other methods.

[0090] Reference Figure 7 As shown, in some embodiments of this application, the transmission member 140 is fixedly connected to the support member 120 or the reinforcing member 130; of course, the transmission member 140 can also be fixedly connected to both the support member 120 and the reinforcing member 130.

[0091] The transmission component 140 includes a transmission shaft 141 and a transmission bracket 142; different transmission brackets 142 of the same transmission shaft 141 can be fixedly connected to the support component 120 and the reinforcing component 130 respectively. The advantage of this is that the position or area of ​​the stop device 100 with appropriate structural strength can be selected according to the magnitude of the transmission force.

[0092] Reference Figure 11 As shown, this application also provides a vehicle 1, which includes the aforementioned front bumper assembly 10 or the aforementioned stop device 100. The vehicle 1 has all the beneficial effects of the aforementioned front bumper assembly 10 or the aforementioned stop device 100, which will not be repeated here.

[0093] The vehicle 1 may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.
