Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a vehicle cooling damper and a vehicle cooling fan. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for comfort during vehicle use, especially new energy vehicles. In addition to the engine, many parts of the vehicle actually have noise during operation. It is just that the noise of the engine is louder, so the noise of other parts is masked by the noise of the engine and is relatively less prominent. However, if you want to improve the overall comfort of the vehicle, it is important to improve the noise of automobile products from various noise sources.

[0003] At present, mainstream radiator fans are generally driven by motors, and the motor start and stop are controlled by temperature sensors. When the temperature is low, the fan will stop rotating. Higher-end radiator fan assemblies will also be equipped with an intake damper. When the vehicle is driving at low speed, the fan provides cooling air, and the damper is closed to prevent air leakage; when the vehicle is driving at high speed, the fan slows down or even stops, and the intake damper opens naturally to compensate for the intake air.

[0004] However, the current design of the damper of the car radiator cooling fan assembly considers its opening and closing efficiency more, but takes less consideration of the impact of noise. When the damper is frequently opened / closed, the damper will produce noise due to collision. In addition, if the damper is not well sealed when closed, the air volume will leak out, reducing the efficiency of the fan and giving the car owner a bad experience. Summary of the invention

[0005] Based on the above description, the present invention provides a vehicle heat dissipation damper and a vehicle heat dissipation fan to solve the problems of noise generated when the damper is closed and insufficient sealing.

[0006] According to a first aspect of the present invention, there is provided a vehicle cooling air door, comprising a door frame and a door panel, wherein the upper portion of the door panel is pivotally connected to the upper portion of the door frame, and when the door panel naturally droops, the edge of the door panel abuts against the door frame; the edge of the door panel is provided with a flexible layer, and the flexible layer is tightly matched with the door frame.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the flexible layer is made of rubber.

[0009] Furthermore, the door frame is provided with a transversely arranged rotating shaft, and the upper part of the door panel is provided with a transversely arranged pivot sleeve, and the pivot sleeve is sleeved on the outer periphery of the rotating shaft and rotatably cooperates with the rotating shaft.

[0010] Furthermore, a transversely arranged pivot sleeve is provided on the upper portion of the door frame, a transversely arranged rotating shaft is provided on the upper portion of the door panel, and the pivot sleeve is sleeved on the outer periphery of the rotating shaft and rotatably cooperates with the rotating shaft.

[0011] Furthermore, limiting protrusions are respectively provided on both sides of the upper end of the door frame, and the two limiting protrusions cooperate with each other to form a limiting groove, and the door panel is arranged in the limiting groove.

[0012] Furthermore, the lower end of the door frame is inclined toward the air outlet direction, and an angle α between the door frame and the vertical direction is less than 45°.

[0013] Furthermore, the upper portion of the door panel 2 is arranged on the air inlet side of the door frame, and the lower portion of the door panel is arranged on the air outlet side of the door frame.

[0014] According to a second aspect of the present invention, there is further provided a vehicle cooling fan, comprising the aforementioned vehicle cooling air door, wherein a plurality of the air doors are dispersedly arranged on the periphery of the fan, and the air outlet directions of the fan and the air doors are consistent.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects: a flexible layer is arranged at the edge of the door panel, and when the damper is closed, the flexible layer at the edge of the door panel is tightly matched with the door frame. Firstly, it provides a shock-absorbing and buffering function, which can reduce the noise generated by the impact during the closing process of the damper. Secondly, it can enhance the sealing of the damper in the closed state, and when the vehicle is driving at a low speed and only the fan is used to provide cooling air, it can prevent the air leakage and improve the energy efficiency of the fan.

[0023] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] It will be appreciated that spatial relationship terms such as "under", "beneath", "below", "under", "above", "above", etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation.

Therefore, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0026] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0027] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0028] See also Figure 1-2 , Figure 1 The three-dimensional structure of the vehicle cooling air door provided by the embodiment of the present invention after installation is shown. Figure 2 (a) shows the front structure of the cooling air door for the vehicle. Figure 2 (a) shows the side cross-sectional structure of the vehicle cooling air door.

[0029] like Figure 1-2 As shown, the present embodiment provides a vehicle cooling air door, comprising a door frame 1 and a door panel 2, wherein the upper portion of the door panel 2 is pivotally connected to the upper portion of the door frame 1, and when the door panel 2 naturally droops, the edge of the door panel 2 abuts against the door frame 1; a flexible layer 201 is provided at the edge of the door panel 2, and the flexible layer 201 is tightly fitted with the door frame 1.

[0030] It can be understood that a flexible layer 201 is provided at the edge of the door panel 2. When the damper is closed, the flexible layer 201 at the edge of the door panel 2 is tightly fitted with the door frame 1. The flexible layer 201 is elastic. Firstly, it provides a shock-absorbing and buffering function, thereby reducing the noise generated by the collision between the edge of the door panel 2 and the door frame 1 during the closing process of the damper. Secondly, since the flexible layer 201 can be deformed, the sealing of the damper in the closed state can be enhanced. When the vehicle is running at a low speed and only the fan 3 provides cooling air, the air leakage is prevented, thereby improving the energy efficiency of the fan 3.

[0031] Based on the above technical solution, this embodiment can also be improved as follows.

[0032] In one possible implementation, the flexible layer 201 is made of rubber material, especially high temperature resistant rubber material, such as silicone rubber, chloroprene rubber, etc. Considering the working environment of the damper in the present invention, it is arranged adjacent to the radiator of the automobile, so the material selection of the flexible layer 201 needs to meet the elasticity requirements and also needs to consider its temperature resistance. Heat resistant rubber has the above two characteristics and can be used as a preferred material.

[0033] In one possible implementation, Figure 2 The structure of the door panel 2 and the door frame 1 cooperating with each other is shown. Figure 3 (a) shows the front view of the door panel 2, Figure 3 (b) shows a side cross-sectional view of the door panel 2, Figure 4 The three-dimensional structure diagram of the door frame 1 is shown. Figure 4 As shown, the door frame 1 is provided with a horizontally arranged rotating shaft 101; Figure 3 As shown, a transversely arranged pivot sleeve 202 is provided on the upper part of the door panel 2 , a pivot hole is provided in the pivot sleeve 202 , and the pivot hole of the pivot sleeve 202 is sleeved on the outer periphery of the rotating shaft 101 and rotatably cooperates with the rotating shaft 101 .

[0034] In one possible implementation manner, a method different from Figure 3 as well as Figure 4 In the scheme shown, the upper part of the door frame 1 is provided with a transversely arranged pivot sleeve (not shown in the figure), the upper part of the door panel 2 is provided with a transversely arranged rotating shaft (not shown in the figure), a pivot hole is provided in the pivot sleeve, and the pivot hole of the pivot sleeve is sleeved on the outer periphery of the rotating shaft and rotatably cooperates with the rotating shaft.

[0035] The above two embodiments can realize the pivotal cooperation between the door panel 2 and the door frame 1 .

[0036] In one possible implementation, Figure 4 As shown, the upper ends of the door frame 1 are provided with limiting protrusions 102, and the two limiting protrusions 102 cooperate with each other to form limiting grooves, and the door panel 2 is arranged in the limiting grooves. When the door panel 2 and the door frame 1 are relatively pivoted, the setting of the limiting grooves limits the position of the door panel 2 in the axial direction of the rotating shaft 101, and prevents the door panel 2 from being separated from the door frame 1.

[0037] In one possible implementation, Figure 1 As shown, the lower end of the door frame 1 is inclined toward the air outlet direction, and the angle α between the door frame 1 and the vertical direction is less than 45°.

[0038] It can be understood that the mating surface between the door frame 1 and the door panel 2 is inclined at a small amplitude. Due to the gravity of the door panel 2, the damper remains closed under small vibration, which reduces the number of collisions between the door panel 2 and the door frame 1 during driving to a certain extent, thereby reducing vehicle noise and preventing air leakage caused by the opening of the damper when the vehicle is driving at low speed, thereby reducing the efficiency of the cooling fan 3.

[0039] In one possible implementation, Figure 2 As shown in (b), the upper portion of the door panel 2 is arranged on the air inlet side of the door frame 1, and the lower portion of the door panel 2 is arranged on the air outlet side of the door frame 1. By matching the upper portion of the door panel 2 with the air inlet side of the door frame 1 and the lower portion of the door panel 2 with the air outlet side of the door frame 1, the sealing performance of the door panel 2 and the door frame 1 can be improved.

[0040] Based on the above-mentioned damper embodiments, Figure 5 As shown, this embodiment provides a vehicle cooling fan. Figure 5 As shown, the heat dissipation fan 3 includes a plurality of dampers, and the plurality of dampers are dispersedly arranged on the periphery of the fan 3, and the air outlet direction of the fan 3 is consistent with that of the dampers.

[0041] The present invention provides a vehicle cooling damper and a vehicle cooling fan, wherein a plurality of dampers are dispersedly arranged on the periphery of the fan 3, and a flexible layer 201 is provided on the edge of the door panel 2 of the damper. When the damper is closed, the flexible layer 201 on the edge of the door panel 2 is tightly matched with the door frame 1, which can provide a shock-absorbing and buffering function to reduce the noise generated by the impact during the closing process of the damper, and can enhance the sealing of the damper in the closed state. When the vehicle is traveling at a low speed and only the fan 3 provides cooling air, the air volume is prevented from leaking, thereby improving the energy efficiency of the fan 3.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
