Description

Technical Field

[0001] The invention relates to the technical field of automobile heat dissipation, and in particular to an automobile air deflector structure and an automobile heat dissipation mechanism and an automobile having the same. Background Art

[0002] At present, in the automotive industry, traditional fuel vehicles have no endurance pressure, and in order to meet the heat dissipation requirements, a front grille 1 is added to the middle area of ​​the front bumper of the vehicle for heat dissipation. At the same time, the grille 1 also satisfies the aesthetics of the entire vehicle. However, with the continuous development of new energy vehicles, major automakers are currently developing new energy vehicles. New energy vehicles use batteries to power the entire vehicle. Affected by the existing battery capacity, new energy vehicles currently use lightweight and reduced drag coefficients to improve endurance. However, the grille 1 will increase wind resistance, which will cause a contradiction. It is necessary to ensure the heat dissipation requirements of the entire vehicle through the grille 1 and to minimize the problem of increased wind resistance caused by the grille 1 as much as possible to ensure endurance.

[0003] like Figure 1 As shown, many new energy vehicles currently design an external active air intake grille 1 with controllable blades to open or close in the area around the front bumper to meet the heat dissipation and endurance requirements. When heat dissipation is needed, the blades of the external active air intake grille 1 are opened, and when the endurance needs to be improved, the blades of the external active air intake grille 1 are closed.

[0004] To ensure that there is enough air intake to ensure cooling of the heat sink 2, Figure 3 As shown, the size of the opening 3 after the active air intake grille 1 is opened is generally designed to be relatively large, which can increase the flow of airflow and achieve a better heat dissipation effect. However, a larger opening 3 size may also cause larger gravel or foreign matter to enter the vehicle from the blade opening 3 and accumulate at the front end of the heat dissipation device 2, or even damage the condenser sheet on the heat dissipation device 2, affecting the heat dissipation of the entire vehicle. A smaller opening 3 size is designed to block gravel and other foreign matter, but it cannot guarantee sufficient air intake, and the heat dissipation effect cannot be achieved. It is impossible to strike a balance between sufficient air intake and preventing gravel and other foreign matter. Summary of the invention

[0005] In view of this, an object of the present invention is to provide an automobile air deflector structure and an automobile heat dissipation mechanism and an automobile having the same, which can ensure sufficient air intake for automobile heat dissipation while also protecting the radiator.

[0006] The present invention provides an automobile wind deflector structure, comprising a wind deflector and an air intake grille, wherein a plurality of air intake holes are formed on the surface of the air intake grille, and the air intake grille is connected to the wind guide surface of the wind deflector through the side edge of the surface.

[0007] Optionally, the diameter of the inscribed circle of the air inlet hole is not less than 15 mm and not more than 45 mm.

[0016] The automobile air deflector structure, automobile heat dissipation mechanism and automobile having the same provided by the present invention protect the radiator in the automobile by arranging the air intake grille at the air deflector. Since the air intake grille is arranged in the automobile, it does not affect the air intake volume of the front air inlet of the automobile.

DETAILED DESCRIPTION

[0026] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The terms "first", "second", "third", etc. are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0030] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0031] In the cooling system of a car, in order to ensure that all the air entering from the active air intake grille can be used for heat dissipation by the heat dissipation device, an air guide plate part is designed between the heat dissipation device and the active air intake grille to guide the air entering from the active air intake grille to the condensing plate of the radiator, so as to achieve better heat dissipation effect. The structure provided in this embodiment is designed in combination with the air guide plate.

[0032] Specifically, Figures 3 to 5 As shown, the present embodiment provides an automobile wind deflector structure, including a wind deflector 10 and an air intake grille 20. A plurality of air intake holes 21 for air to pass through are formed by a plurality of bars 22 intersecting on the surface of the air intake grille 20. The air intake grille 20 is connected to the wind guide surface 16 of the wind deflector 10 through the side of the surface. The wind guide surface 16 of the wind deflector 10 is a surface for guiding the airflow, and is set as the windward surface of the wind deflector 10.

[0033] The structure provided in this embodiment is used to be installed inside the car and is located in front of the radiator. When the external airflow flows to the radiator of the car through the air inlet of the car, the airflow will first flow through the air guide plate 10, and the airflow will be completely guided to the radiator under the guidance of the air guide plate 10 to cool the radiator. The air intake grille 20 on the air guide plate protects the radiator. The bars 22 on the air intake grille 20 cross to form air intake holes 21. These air intake holes 21 allow airflow to pass through, and the bars 22 can block foreign objects such as gravel from approaching the radiator, so that foreign objects such as gravel are blocked at the air intake grille 20. Since the air intake grille 20 is set at the air guide plate 10 inside the car, the size of the air intake holes 21 of the air intake grille 20 will not affect the size of the airflow entering the car, and the air intake grille 20 also protects the radiator, ensuring that the air intake volume for heat dissipation of the car is sufficient while protecting the radiator.

[0034] Among them, the number of air guide plates 10 is one or more, and the opposite ends of these air guide plates 10 are respectively connected to the air inlet 31 and the radiator, and the air guide plates 10 and the internal structure of the vehicle body or the air guide plates 10 and the air guide plates 10 form a guide channel. The air intake grille 20 is located in the guide channel and the side of the air intake grille 20 is connected to the air guide plate 10 to ensure that the airflow passes completely through the air intake grille 20.

[0035] In this embodiment, the structure of the automobile air guide plate 10 includes a frame, an upper air guide plate 11 and a lower air guide plate 12. The frame includes two opposite vertical plates 15. The upper air guide plate 11 and the lower air guide plate 12 are connected between the two vertical plates 15, and the air guide surfaces 16 of the upper air guide plate 11 and the lower air guide plate 12 are opposite. The two vertical plates 15, the upper air guide plate 11 and the lower air guide plate 12 are enclosed to form a guide channel. The guide channel is connected to the air inlet 31 of the automobile. The four opposite sides of the air intake grille 20 are respectively connected to the air guide surfaces 16 of the upper air guide plate 11 and the lower air guide plate 12 and the two vertical plates 15, ensuring that the airflow flowing into the guide channel completely flows through the air intake grille 20 to protect the radiator. The air intake grille 20 is located inside the automobile, which can also reduce the probability of the air intake grille 20 being damaged by foreign objects.

[0036] The air intake holes 21 formed by the intersection of the bars 22 of the air intake grille 20 can be in any shape, not limited to triangle, square, rectangle or other polygons, as well as other shapes such as circle or ellipse. However, the diameter of the inscribed circle of the air intake hole 21 is not less than 15mm and not more than 45mm. Such a size can block the size of foreign objects such as gravel commonly seen in the process of automobile formation, and can ensure that the airflow is less blocked.

[0037] The front of the car is provided with an air inlet for taking air into the car. For the sake of aesthetics or size requirements, the size of the air inlet will not be too large, while the size of the radiator in the car is larger than the size of the air inlet. For this reason, the air guide plate 10 is in a curved shape. The curved shape of the air guide plate 10 can adapt to the in-car environment and facilitate the airflow to be fully directed to the radiator. The air guide plate 10 includes a connecting section 13 and a curved section 14. The angle between the connecting section 13 and the curved section 14 is not greater than 90°. The air intake grille 20 is connected to the connecting section 13 of the air guide plate 10. The connecting section 13 is used to connect to the air inlet provided at the front of the car. The curved section 14 is used to connect to the radiator, which facilitates the airflow to be fully directed to the radiator. The air intake grille 20 is connected to the connecting section 13 and keeps a distance from the air inlet. When the air intake grille 20 blocks foreign objects such as gravel, the foreign objects such as gravel can be blocked at the position before the air guide plate 10 is bent, which facilitates the subsequent cleaning of foreign objects such as gravel.

[0038] Furthermore, the air intake grille 20 and the air guide plate 10 are detachably connected, and the detachable connection between the air intake grille 20 and the air guide plate 10 can be achieved by snapping the air intake grille 20 and the air guide plate 10 together or connecting them through other fasteners. When a lot of gravel or other foreign matter is accumulated in front of the air intake grille 20, causing the air intake holes 21 of the air intake grille 20 to be blocked, the air intake grille 20 can be removed for cleaning.

[0039] In summary, the automobile air deflector structure provided in this embodiment can provide sufficient air intake for automobile heat dissipation and protect the radiator.

[0040] like Figure 6 and Figure 7 As shown, the present embodiment further provides an automobile heat dissipation mechanism, including a front part 30, a radiator (not shown) and the automobile air guide plate structure as described above, the front part 30 is provided with an air inlet 31, the radiator is located in the vehicle body and an air inlet channel is formed between the air inlet 31 and the radiator, the air guide plate 10 is located in the air inlet channel, and is used to guide the airflow entering at the air inlet 31 to the radiator, and the airflow flows through the air inlet hole 21 of the air intake grille 20.

[0041] Since the air intake grille 20 is located inside the car, when the air intake grille 20 blocks foreign objects such as gravel, the gravel and other foreign objects are accumulated in front of the air intake grille 20. These gravel and other foreign objects are located inside the car and need to be cleaned regularly. In order to facilitate the cleaning of these gravel and other foreign objects, the distance between the air intake grille 20 and the air inlet 31 is 150mm-200mm, ensuring that the user can easily clean the foreign objects in front of the air intake grille 20.

[0042] At the same time, since the air intake grille 20 is located inside the car and is close to the radiator, a certain distance must be maintained between the air intake grille 20 and the radiator to ensure that the air intake grille 20 will not touch the radiator during a low-speed collision, thereby avoiding damage to the radiator during a low-speed collision. To this end, the distance between the air intake grille 20 and the radiator is not less than 80 mm to reduce the probability of radiator damage.

[0043] Furthermore, the automobile heat dissipation mechanism provided in this embodiment also includes blades 40 and a blade 40 driving unit for driving the blades 40 to move. The blades 40 are located in the vehicle body. The blades 40 are driven by the blade 40 driving unit to close or open the air inlet 31. When the automobile needs to be cooled, the blades 40 are opened, and the air flows from the air inlet 31 to the radiator. When cooling is not required, the blades 40 are closed to reduce wind resistance and prevent foreign objects such as gravel from entering the vehicle. The overall use is more flexible. The opening and closing of the blades 40 at the air inlet 31 of the automobile is a mature technology at present, which will not be described in detail here.

[0044] In summary, the automobile heat dissipation mechanism provided in this embodiment can ensure a good heat dissipation effect while reducing the risk of radiator damage, and the automobile can switch between heat dissipation and wind resistance reduction at any time by opening and closing the blades 40.

[0045] This embodiment also provides a car, comprising the car heat dissipation mechanism as described above.

[0046] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
