[0034] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] The heat sink at the front end of the vehicle is provided with a deflector, which is used to provide air guide and front end sealing for the heat sink. Meanwhile, the front bumper assembly at the front end of the vehicle is integrated with a large number of electrical configuration parts and has a self-weight problem. A sinking prevention member is arranged for the front bumper assembly to bear the weight in the middle of the bumper skin and prevent the sinking of the bumper.

[0036] In the related art, the lifting block is integrated on the deflector. When assembling the front end system of the vehicle, the part of the rear side of the deflector is connected with the upper cross beam of the heat sink, and the front side of the deflector lifts the front bumper assembly to make the front bumper assembly located at the front end of the vehicle. Then, the front hood is arranged above the upper cross beam of the heat sink and the front bumper assembly to complete the assembly.

[0037] However, the lifting block lifting the front bumper assembly is easy to make the front bumper assembly displace and sink, thereby reducing the installation stability of the front bumper assembly.

[0038] Therefore, the deflector structure, the heat sink and the vehicle are provided. The deflector structure is provided with a deflector and a limiting assembly. The deflector is used to be connected with the heat sink of the vehicle. The limiting assembly includes a first limiting piece and a second limiting piece. One of the first limiting piece and the second limiting piece is arranged on one side of the deflector, and the other is used to be connected with the front bumper assembly of the vehicle. In use, the first limiting piece and the second limiting piece are inserted to limit the freedom degree of the front bumper assembly in the width direction and the height direction of the vehicle, so that the displacement and sinking of the front bumper assembly can be avoided, and the installation stability of the front bumper assembly is improved.

[0039] The present application will be described in detail below in combination with the drawings and specific embodiments.

[0040] Referring to Figures 1 to 3 The deflector structure 100 provided by the embodiments of the present application includes a deflector 110 and a limiting assembly 120. The deflector 110 is used to be connected with the heat sink 200 of the vehicle. The limiting assembly 120 includes a first limiting piece 121 and a second limiting piece 122. One of the first limiting piece 121 and the second limiting piece 122 is arranged on one side of the deflector 110, and the other is used to be connected with the front bumper assembly 300 of the vehicle. The first limiting piece 121 and the second limiting piece 122 are inserted.

[0041] In specific implementation, one side of the deflector 110 is the rear side of the deflector 110, and the other side of the deflector 110 is the front side of the deflector 110. The rear side refers to the side close to the tail of the vehicle, and the front side refers to the side close to the head of the vehicle.

[0042] Specifically, the air guide 110 is configured to provide an air guide path for air to flow through the radiator 200 to achieve a cooling effect; one of the first and second limiters 121 and 122 is connected with the air guide 110, and the two are used as a whole; the other of the first and second limiters 121 and 122 is connected with the front bumper assembly 300, and the first and second limiters 121 and 122 are inserted to limit the freedom of the front bumper assembly 300 in the vehicle width direction and the height direction, so that the front bumper assembly 300 can be prevented from being displaced and sunk, and the installation stability of the front bumper assembly 300 is improved.

[0043] It can be understood that the front bumper assembly 300 is an external covering member at the front end of the vehicle, and the front bumper assembly 300 can include a front bumper skin, an upper grille, a lower grille, a fog lamp, and an electrical element such as a wire harness, a washing element, and a camera; the radiator upper cross beam 211 is configured to provide structural support and stability for the radiator 200, and to ensure that the radiator 200 remains stable during vehicle operation, especially when facing road bumps or collisions.

[0044] Referring to Figure 1 , Figure 2 and Figure 4 , in some examples, one of the first and second limiters 121 and 122 includes at least two limiting portions 1211, and the other includes at least two limiting grooves 1212; the limiting portions 1211 and the limiting grooves 1212 are one-to-one correspondingly inserted.

[0045] Exemplarily, the first limiter 121 includes at least two limiting grooves 1212, and the second limiter 122 includes at least two limiting portions 1211; the at least two limiting grooves 1212 are arranged on one side of the air guide 110, and each limiting groove 1212 is arranged in a spaced manner along the extension direction of the air guide 110; the limiting groove 1212 and the limiting portion 1211 on the front bumper assembly 300 are one-to-one correspondingly inserted.

[0046] The extension direction of the air guide 110 is the X direction in Figure 4 , which is parallel to the width direction of the vehicle.

[0047] The number of limiting portions 1211 and limiting grooves 1212 is at least two, which is beneficial to make the overall stress of the air guide 110 more uniform when limiting and supporting the front bumper assembly 300 through the air guide 110, and improves the balance stability of the front bumper assembly 300.

[0048] Referring to Figure 1 and Figure 3In some examples, the air guide structure 100 further comprises an energy absorbing member 130 connected with the air guide member 110; the other side of the air guide member 110 is arranged opposite to the upper beam 211 of the radiator, and the energy absorbing member 130 is arranged above the upper beam 211 of the radiator, and the energy absorbing member 130 is used to buffer and absorb the external force transmitted to the upper beam 211 of the radiator through the front hood of the vehicle.

[0049] In this way, during assembly, the other side of the air guide member 110 is arranged opposite to the upper beam 211 of the radiator to form a space for air flow, thereby providing the radiator 200 with air guiding effect; the energy absorbing member 130 is connected with the air guide member 110, so that the energy absorbing member 130 is arranged above the upper beam 211 of the radiator; finally, the front hood is arranged above the energy absorbing member 130, and the energy absorbing member 130 is arranged opposite to the front hood of the vehicle.

[0050] In this way, when a person collides with the vehicle, the energy absorbing member 130 is used to buffer and absorb the external force transmitted to the upper beam 211 of the radiator through the front hood, on the one hand, buffering and absorbing the external force by the energy absorbing member 130 can reduce the head injury value of the person, on the other hand, the external force received by the air guide member 110 and the upper beam 211 of the radiator can be reduced, thereby reducing the shaking or damage of the air guide member 110 and the upper beam 211 of the radiator, and improving the connection stability of the air guide member 110 and the upper beam 211 of the radiator.

[0051] Referring to Figure 3 and Figure 4 In some embodiments, the energy absorbing member 130 comprises a fixed segment 131, a bent segment 132 and an extension segment 133; one side of the fixed segment 131 is connected with the air guide member 110, and the other side of the fixed segment 131 extends in a first direction away from the air guide member 110; the bent segment 132 is connected with the other side of the fixed segment 131; the extension segment 133 is connected with the bent segment 132 to extend in a second direction away from the air guide member 110, and the extension segment 133 is arranged above the upper beam 211 of the radiator; wherein the first direction and the second direction are perpendicular.

[0052] The first direction is the Z direction in the Figure 4 , which is parallel to the height direction of the vehicle; and the second direction is the Y direction in the Figure 4 , which is parallel to the length direction of the vehicle.

[0053] In this way, by connecting the fixed segment 131 and the extension segment 133 through the bent segment 132, the fixed segment 131 and the air guide member 110 are arranged in the same plane and arranged opposite to the upper beam 211 of the radiator to form a space for air flow; at the same time, the extension segment 133 is arranged above the upper beam 211 of the radiator to ensure that the energy absorbing member 130 is assembled smoothly.

[0054] In a specific implementation, the fixed section 131, the bent section 132, and the extended section 133 can be integrally formed. Specifically, the integrally forming process refers to the forming process of the entire component in one mold at one time. Compared with the traditional manufacturing process with multiple steps, the integrally forming process can simplify the manufacturing process, and has high precision, high production efficiency, and low production cost.

[0055] In this way, the problem of loose connection between the fixed section 131, the bent section 132, and the extended section 133 can be avoided, and the structural reliability of the energy-absorbing member 130 can be ensured.

[0056] Further, the integrally forming process can avoid additional processing between the fixed section 131, the bent section 132, and the extended section 133, which is beneficial to improve the production efficiency and reduce the production cost.

[0057] For example, the fixed section 131 and the extended section 133 can both be plate-shaped structures, and the bent section 132 can be an arc-shaped bent section 132. In this way, the stress concentration can be reduced, and the service life of the bent section 132 can be improved.

[0058] In a specific example, the energy-absorbing member 130 is a polypropylene composite filled with ethylene propylene diene monomer (EPDM) and talcum powder, and / or the air guide member 110 is a polypropylene composite filled with glass fiber.

[0059] The energy-absorbing member 130 is a polypropylene composite filled with ethylene propylene diene monomer (EPDM) and talcum powder (PP EPDM-T). The addition of EPDM can improve the toughness and impact resistance of the energy-absorbing member 130, so that the material of the energy-absorbing member 130 is relatively soft. Specifically, EPDM has good elasticity and impact resistance, so that the energy-absorbing member 130 can effectively buffer and disperse energy when a collision occurs, thereby reducing the damage to the head of a person. In addition, EPDM has weather resistance and anti-aging properties, so that the energy-absorbing member 130 can work stably for a long time in various environments and reduce the maintenance requirement.

[0060] The air guide member 110 is a polypropylene composite filled with glass fiber (PP-GF). The addition of glass fiber can improve the mechanical strength and rigidity of the air guide member 110, so that the air guide member 110 can maintain stable shape during high-speed driving of the vehicle, and ensure the efficiency of air flow through the radiator 200.

[0061] Continuing to refer to Figure 4 In some examples, the energy-absorbing member 130 has at least one first connecting portion 134, and the air guide member 110 has at least one second connecting portion 111. The first connecting portion 134 and the second connecting portion 111 are in one-to-one correspondence and can be detachably connected.

[0062] Thus, by adopting the detachable connection mode, when one of the energy absorbing member 130 and the air guide member 110 needs to be replaced due to damage, aging, etc., it is not necessary to replace all, but only one needs to be replaced, which is beneficial to reduce maintenance cost and time.

[0063] Exemplarily, the first connecting part 134 and the corresponding second connecting part 111 are snap joints, wherein the first connecting part 134 can be a first buckle, and the second connecting part 111 is a second buckle matched with the first connecting part 134. Alternatively, the first connecting part 134 and the corresponding second connecting part 111 are screw joints, wherein one of the first connecting part 134 and the second connecting part 111 is a screw, and the other is a threaded hole matched with the screw.

[0064] It can be understood that in use, the first connecting part 134 is arranged on the fixed section 131.

[0065] The specific number of the first connecting part 134 and the second connecting part 111 in the embodiments of the present application can be set according to actual conditions, which is not limited in the embodiments of the present application. For example, the first connecting part 134 and the second connecting part 111 are both one, and the assembly of the energy absorbing member 130 and the air guide member 110 can be realized through the detachable connection of one first connecting part 134 and second connecting part 111; of course, the first connecting part 134 and the second connecting part 111 can also be two as shown, so that the assembly of the energy absorbing member 130 and the air guide member 110 is more stable. Figure 4

[0066] In some examples, the energy absorbing member 130 is welded with the air guide member 110.

[0067] Thus, by means of welding, the risk of loosening or separation between the energy absorbing member 130 and the air guide member 110 caused by vibration or other external forces can be reduced, and the reliability of the connection and the reliability of long-term use can be ensured.

[0068] It can be understood that the welding point usually has good sealing property, which can prevent moisture, dust and other contaminants from entering the joint, and can enhance the durability of the energy absorbing member 130 and the air guide member 110 under various environmental conditions.

[0069] The welding mode of the energy absorbing member 130 and the air guide member 110 is not limited in the embodiments of the present application. Exemplarily, the energy absorbing member 130 is a ternary ethylene-propylene rubber and talcum powder filled polypropylene composite member, and the air guide member 110 is a glass fiber reinforced polypropylene composite member; the two can be welded by one of hot melt welding, ultrasonic welding and infrared welding.

[0070] In order to facilitate the butt joint of the energy absorbing member 130 and the air guide member 110 during assembly, in specific implementation, reference can be made to Figure 3 and​Figure 4 The air guide 110 further has a guide portion 112 above the second connecting portion 111; the guide portion 112 includes a first guide surface 1121, and the energy absorbing member 130 includes a second guide surface 1341 matched with the first guide surface 1121, which is used to abut with the first guide surface 1121 in sliding fit when the first connecting portion 134 and the second connecting portion 111 are connected.

[0071] The guide portion 112 can be a stepped groove as shown in Figure 4 The first guide surface 1121 is a first stepped surface in L shape as shown in Figure 4 The second guide surface 1341 of the energy absorbing member 130 is a second stepped surface in L shape on the structure of the portion of the fixed segment 131 away from the bent segment 132. In this way, when the first connecting portion 134 of the energy absorbing member 130 and the second connecting portion 111 of the air guide 110 are connected, the second stepped surface and the first stepped surface are in sliding fit and abut, so that the energy absorbing member 130 is more smoothly butted and placed on the air guide 110; at the same time, the connection between the energy absorbing member 130 and the air guide 110 can be sealed to ensure the reliable connection.

[0072] It can be understood that by arranging the guide portion 112 above the second connecting portion 111, the relative positions of the two are reasonably arranged, and the contact fit between the first guide surface 1121 and the second guide surface 1341 does not interfere with the connection between the first connecting portion 134 and the second connecting portion 111.

[0073] Referring to Figure 4 and Figure 5 In some embodiments, the energy absorbing member 130 further has a third connecting portion 135 on the opposite sides of the energy absorbing member 130; the third connecting portion 135 is used to connect with the upper beam 211 of the heat sink.

[0074] In this way, the third connecting portion 135 makes the energy absorbing member 130 more stably overlapped above the upper beam 211 of the heat sink, and in the process of buffering and absorbing external force by the energy absorbing member 130, the displacement of the energy absorbing member 130 can be reduced, and the connection stability of the air guide structure 100 and the upper beam 211 of the heat sink is ensured.

[0075] Exemplarily, as shown in Figure 5 A through hole 1351 can be formed on the third connecting portion 135, and a screw 1352 passes through the through hole 1351 and is connected with a threaded hole on the upper beam 211 of the heat sink, so that the third connecting portion 135 is connected with the upper beam 211 of the heat sink. In this way, it is convenient to disassemble and maintain.

[0076] Of course, the third connecting part 135 can also be welded with the radiator upper beam 211 as a whole, and the embodiments of the present application do not limit this.

[0077] Referring to Figure 3 The embodiments of the present application provide a radiator 200, comprising a radiator body 210 and a wind guide structure 100 provided on the radiator body 210, as in any of the preceding embodiments.
