Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle accessories, and particularly to an intake grille and a vehicle. Background Art

[0002] The active intake grille system is an intake grille adjustment system, which includes an automotive water temperature sensor or a temperature control switch, a control unit, and an active intake grille. The active intake grille is generally installed directly in front of the vehicle head. During vehicle driving, its opening degree can be adjusted through the control of the control unit, so as to adjust the cooling air volume entering the engine compartment, thereby reducing the internal circulation resistance during vehicle driving and improving the fuel economy of the whole vehicle.

[0003] At the same time, in the cold vehicle state, the active intake grille system can quickly increase the engine operating temperature by closing the grille and cooperating with the electronic thermostat, enabling the on-board diagnostic system (OBD) to enter the closed-loop working state earlier.

[0004] In summary, by changing the opening and closing angle of the intake grille, the intake air volume of the engine compartment and the wind resistance of the whole vehicle can be controlled, and the active intake grille system has the functions of improving the fuel economy of the whole vehicle and accelerating the engine warm-up process.

[0005] The active intake grille system has been applied to many domestic and foreign vehicle models. Taking the Focus as an example, its application is briefly described below. The active intake grille of the Focus is installed at the grille opening in front of the radiator. The grille blades can rotate into 15 different states from fully closed to fully open, with a maximum rotation amplitude of 90°. When air is needed to cool the engine, the grille blade group will open, and vice versa, which reduces the wind resistance of the Focus. When the vehicle is started in the cold vehicle state, the active closing system of the active intake grille can control the grille blades to remain closed for a long time, enabling the engine to reach the appropriate operating temperature faster, which can also help reduce fuel consumption. If the vehicle is driving at a constant speed of 120 km / h, the active intake grille system can save an average of 0.15 - 0.20 L / 100 km of fuel for the Focus. When the active intake grille is fully closed to reduce wind resistance, the carbon dioxide emissions can be reduced by 2%.

[0006] However, the snow and water on the above-mentioned active intake grille are not easily discharged and are prone to freezing at low temperatures, thus locking the grille blades and causing the loss of the function of the active intake grille blades. Summary of the Invention

[0034] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

[0035] The intake grille is installed between the front grille and the radiator; wherein, the height of the front grille is less than the height of the radiator, so that the height of the rear part of the intake grille is greater than the height of the front part of the intake grille, and the first intake passage is mainly located in the front part of the intake grille; therefore, in order to enable the wind entering from the first intake passage to contact the radiator more fully and over a larger area, the lower end of the first blade generally rotates towards the front grille direction, that is, the first blade rotates in the first direction, so that the wind in the first intake passage blows from bottom to top, and then contacts the radiator over a larger area, thereby enabling faster heating or cooling;

If the first blade is forced to rotate in the first direction, it may cause the motor to burn out. Therefore, when the sensor detects such a situation, it sends a signal to make the first blade rotate in the second direction, that is, the top of the first blade rotates towards the front grille direction, and the bottom of the first blade rotates towards the radiator direction. Thus, the first blade can smoothly rotate to the second state to open the first intake passage.

Detailed Description of the Invention

[0058] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings.

[0060] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms of "a", "the" and "said" used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that the term " / and" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0061] As Figure 1 shown, a vehicle includes a vehicle body 20, a front grille 30 disposed at the front end of the vehicle body 20, a radiator 40 disposed within the vehicle body 20, and an intake grille as Figures 4 - 7 shown. The intake grille is connected and disposed between the front grille 30 and the radiator 40.

[0062] The blades of the intake grille can be adjusted in the opening and closing angle by a motor 12, so as to control the intake air volume of the engine compartment and the vehicle aerodynamic drag, for the purpose of adjusting the cooling air volume entering the engine compartment, thereby reducing the internal circulation resistance during vehicle driving and improving the fuel economy of the whole vehicle.

[0063] It should be noted that the vehicle may be a passenger vehicle, such as a sedan, a bus, a tourist bus, etc. The vehicle may also be a freight vehicle, such as a general freight vehicle, a special vehicle, a dump truck, a tractor, etc. This disclosure does not limit this.

[0064] As Figures 4 - 7As shown in the figure, the intake grille includes a mounting seat 10, a sensor disposed on the mounting seat 10, and a first vane 11. The mounting seat 10 includes a first intake passage 100 extending along its length direction. The first vane 11 extends along the width direction of the mounting seat 10 and is movably mounted in the first intake passage 100. The first vane 11 has a first state and a second state in the first intake passage 100.

[0065] When the first vane 11 is in the first state, the first intake passage 100 is closed.

[0066] When the first vane 11 rotates in the first direction to switch to the second state, the first intake passage 100 is opened.

[0067] When the first vane 11 cannot rotate in the first direction to switch to the second state, the sensor emits a signal to cause the first vane 11 to rotate in the second direction to switch to the second state. The second direction is set opposite to the first direction.

[0068] It should be noted that the first direction in the present disclosure may be clockwise and the second direction may be counterclockwise. Or the first direction may be counterclockwise and the second direction may be clockwise. The present disclosure does not limit this.

[0069] The intake grille in the present disclosure is installed between the front grille 30 and the radiator 40. Among them, the height of the front grille 30 is less than the height of the radiator 40, so that the height of the rear part of the intake grille is greater than the height of the front part of the intake grille, and the first intake passage 100 is mainly located in the front part of the intake grille. Therefore, in order to enable the air entering from the first intake passage 100 to come into more sufficient and larger-area contact with the radiator 40, the lower end of the first vane 11 generally rotates towards the front grille 30, that is, the first vane 11 rotates in the first direction, so that the air in the first intake passage 100 blows from bottom to top, and then comes into larger-area contact with the radiator 40, thereby enabling faster heating or cooling.

[0070] However, foreign matters such as snow accumulation 90 or water accumulation are likely to accumulate at the entrance of the first intake passage 100. In severe winter, the snow accumulation 90 and water accumulation are likely to freeze, thus hindering the first vane 11 from rotating in the first direction. If the first vane 11 is forcibly rotated in the first direction, it may cause the motor 12 to burn out. Therefore, when the sensor senses the occurrence of this situation, it emits a signal to cause the first vane 11 to rotate in the second direction, that is, the top end of the first vane 11 rotates towards the front grille 30, and the bottom end of the first vane 11 rotates towards the radiator 40. Thus, the first vane 11 can be smoothly rotated to the second state to open the first intake passage 100.

[0071] Such as Figure 1 、 Figure 3 and Figure 16As shown in the figure, the vehicle further includes a front bumper 70 disposed at the front end of the vehicle body 20. The front grille 30 is disposed on the front bumper 70. The front bumper 70 includes a drainage channel 700. The water inlet of the drainage channel 700 communicates with the first intake channel 100 and is located in front of the first blade 11. By setting it in this way, the accumulated snow 90 or water at the inlet of the first intake channel 100 can be discharged along the drainage channel 700.

[0072] As Figures 1 - 3 shown in the figure, the vehicle further includes a connecting seat 50. The mounting seat 10 is connected to the radiator 40 through the connecting seat 50. The material of the connecting seat 50 includes a soft material, such as rubber. By setting it in this way, the mounting seat 10 and the connecting seat 50 are assembled through a two-color injection molding structure to achieve a soft-hard combination, thereby reducing the weight of the intake grille and further reducing the weight of the vehicle body 20.

[0073] At the same time, the connecting seat 50 is disposed between the mounting seat 10 and the radiator 40, and the connecting seat 50 is made of a soft material. Furthermore, the connecting seat 50 forms a buffer between the mounting seat 10 and the radiator 40 to avoid damage to the radiator 40 caused by the collision between the mounting seat 10 and the radiator 40.

[0074] As Figure 3 and Figure 5 shown in the figure, a Z-shaped mating form is formed between the connecting seat 50 and the mounting seat 10: that is, the top of the connecting seat 50 overlaps with the top of the mounting seat 10, the bottom of the connecting seat 50 overlaps with the bottom of the mounting seat 10, and the middle part of the connecting seat 50 overlaps with the middle part of the mounting seat 10. Thereby, the overlapping area between the connecting seat 50 and the mounting seat 10 is increased to a great extent, the overlapping strength between the connecting seat 50 and the mounting seat 10 is improved, and the reliability of the intake grille is increased.

[0075] As Figure 15 shown in the figure, the connecting seat 50 includes an interference fit portion 500. The connecting seat 50 overlaps with the radiator 40 through the interference fit portion 500. In the present disclosure, through the interference fit portion 500 of the connecting seat 50, the connecting seat 50 interferes with the periphery of the radiator 40, improving the sealing quality of the intake grille and preventing the engine exhaust gas from flowing back.

[0076] As Figures 1 - 3 shown in the figure, the vehicle further includes a wind guiding seat 60 connected between the front grille 30 and the mounting seat 10. The wind guiding seat 60 includes a second intake channel 600 communicating with the first intake channel 100. Along the intake direction of the second intake channel 600, the cross-sectional area of the second intake channel 600 gradually decreases. The wind guiding seat 60 in the present disclosure is used to connect the front grille 30 and the mounting seat 10, making the installation of the mounting seat 10 more stable and having the function of optimizing the air flow direction at the same time.

[0077] Figure 6It is a top view of the intake grille. As Figure 6 The intake grille shown is provided with a total of six fifth mounting holes 18, two of the fifth mounting holes 18 are arranged at the top of the connecting seat 50, two other fifth mounting holes 18 are arranged at the top of the mounting seat 10, and the last two fifth mounting holes 18 are arranged in the middle of the mounting seat 10. With such an arrangement, the upper surface of the intake grille is mounted on the vehicle body 20 through the six fifth mounting holes 18, and the mounting is stable and the reliability is good.

[0078] Figure 7 It is a bottom view of the intake grille. As Figure 7 The intake grille shown is provided with a total of two sixth mounting holes 19. The two sixth mounting holes 19 are located at the bottom of the mounting seat 10. With such an arrangement, Figure 6 cooperating with the six fifth mounting holes 18 in

[0079] The rotation of the first vane 11 can be realized by a motor 12, a cylinder or other driving members. As Figure 5 shown, the intake grille further includes a motor 12 arranged on the mounting seat 10, a plurality of first vanes 11 and a plurality of rotating shafts 13. The plurality of rotating shafts 13 correspond to the plurality of first vanes 11 one by one. The first vane 11 is rotatably mounted in the first intake passage 100 through the rotating shaft 13. The motor 12 includes an output member 120 connected to one end of one of the rotating shafts 13. The motor 12 drives the plurality of first vanes 11 to rotate so that the plurality of first vanes 11 can be switched between a first state and a second state. In the present disclosure, the motor 12 drives the first vane 11 to rotate, the structure is simple, and it is convenient to control the start and stop of the motor 12 through an electric control circuit.

[0080] It should be noted that the rotation of the plurality of first vanes 11 can be driven by one motor 12, or the plurality of first vanes 11 can be driven by a plurality of motors 12 respectively. The present disclosure does not limit this.

[0081] The rotating shaft 13 in the present disclosure can be fixedly connected to the first vane 11 or integrally formed with the first vane 11. As Figure 9 、 Figure 10 and Figure 16 shown, the rotating shaft 13 in the present disclosure is integrally formed with the first vane 11. The first vane 11 is further provided with a seventh mounting hole 110. The axis line of the seventh mounting hole 110 is parallel to the axis line of the rotating shaft 13. The first vane 11 is rotatably connected to the connecting rod 14 through the seventh mounting hole 110.

[0082] In some embodiments, as Figure 9 、 Figure 10 and Figure 16As shown, the mounting base 10 further includes two first raised strips 101; the two first raised strips 101 are respectively disposed on the top wall and the bottom wall of the first air intake passage 100; wherein, the first raised strip 101 on the top wall is located in front of the first blade 11 in the first state, and there is an overlap in height with the uppermost first blade 11 in the first state; the first raised strip 101 on the bottom wall is located behind the first blade 11 in the first state, and there is an overlap in height with the lowermost first blade 11 in the first state; thus, when all the first blades 11 are in the first state, the first air intake passage 100 can be completely closed, having a good sealing effect; at the same time, the positional relationship between the first raised strip 101 and the first blade 11 will not affect the rotation of the first blade 11 in the first direction at all; but it will affect the rotation of the first blade 11 in the second direction; therefore, the first blade 11 in the present disclosure is formed by an extrusion process, and along the direction from the top end to the bottom end of the first blade 11, the thickness of the first blade 11 first gradually increases and then gradually decreases. By such a setting, both the top end and the bottom end of the first blade 11 become softer, so as to avoid problems such as interference and obstruction between the first blade 11 and the first raised strip 101 of the mounting base 10 when the first blade 11 rotates counterclockwise, and the first blade 11 cannot be opened due to small deformation.

[0083] As an alternative embodiment, the middle part of the first blade 11 is hollow. By such a setting, both the cost and weight of the air intake grille can be reduced, and the strength of the air intake grille can be ensured.

[0084] The output member 120 in the present disclosure can be an output shaft or an output groove. In some embodiments, as Figure 5 and Figure 8 shown, the rotating shaft 13 includes a joint 131. The cross-section of the joint 131 includes an N-sided polygon (N is an integer greater than or equal to three), an ellipse or a flower shape. The output member 120 is an output groove adapted to the joint 131.

[0085] As Figure 5 and Figure 14 shown, in some embodiments, the air intake grille further includes a connecting rod 14. The connecting rod 14 is rotatably connected to a plurality of first blades 11. Specifically, the connecting rod 14 includes a first main body portion 141 and a plurality of first extending portions 142 provided on the side wall of the first main body portion 141. The first extending portions 142 correspond to the first blades 11 one by one. A third mounting hole 140 is provided at the outer end of the first extending portion 142. The connecting rod 14 is rotatably connected to the first blade 11 through the third mounting hole 140. By such a setting, in the present disclosure, a plurality of first blades 11 can be driven to rotate simultaneously by one motor 12, thereby saving costs.

[0086] As an alternative embodiment, the connecting rod 14 further includes a plurality of avoiding grooves. The connecting rod 14 includes a first side wall facing the rotating shaft 13. The plurality of avoiding grooves are all arranged on the first side wall and are arranged in sequence along the longitudinal direction of the connecting rod 14 to respectively avoid the plurality of rotating shafts 13. The connecting rod 14 in the present disclosure can be located between the rotating shaft 13 and the front grille 30, or can be located between the rotating shaft 13 and the radiator 40. At the same time, since the total rotation stroke of the first blade 11 reaches 180°, the horizontal displacement of the first blade 11 is at least the diameter size of the first blade 11. Thus, if the avoiding grooves are not provided, the connecting rod 14 will inevitably collide with the rotating shaft 13. Therefore, the avoiding grooves are provided to prevent the connecting rod 14 from colliding with the rotating shaft 13.

[0087] As Figure 17 shown, a plurality of first blades 11 in the present disclosure are all in the first state, and each first blade 11 contacts each other, thereby closing the first air intake passage 100. At this time, the connecting rod 14 is at the highest point.

[0088] As Figure 18 shown, a plurality of first blades 11 in the present disclosure are all in the second state, and a gas passage is formed between two adjacent first blades 11, thereby opening the first air intake passage 100. At this time, the connecting rod 14 is at the lowest point.

[0089] Combined Figure 17 and Figure 18 . When the motor 12 drives the uppermost first blade 11 to rotate in the second direction, the uppermost first blade 11 drives the connecting rod 14 to move. During the process of the connecting rod 14 moving from the highest point to the lowest point, the connecting rod 14 drives the remaining first blades 11 to rotate in the second direction.

[0090] As Figure 5 and Figure 13 shown, in some embodiments, the air intake grille further includes a pressing plate 15 clamped with the mounting seat 10. The pressing plate 15 includes a plurality of clamping structures 151 for cooperating with the mounting seat 10. The pressing plate 15 further includes a plurality of second mounting holes 150 corresponding to the first blades 11 one by one. The first blade 11 is rotatably connected to the second mounting hole 150 through the other end of the rotating shaft 13. Continue to refer to Figure 5, several first blades 11 in the present disclosure are divided into two columns. The motor 12 is located between the two columns of first blades 11, and the output member 120 of the motor 12 is respectively connected to the uppermost first blades 11 in the two columns of first blades 11. The inner ends of the two columns of first blades 11 are respectively connected by two connecting rods 14. The outer ends of the two columns of first blades 11 are respectively connected by pressing plates 15. In this way, when assembling the intake grille, first assemble the first blades 11, the motor 12, the rotating shaft 13, the connecting rods 14 and the pressing plates 15 into an integral body, and then snap-connect the pressing plates 15 with the mounting seat 10, so as to assemble the first blades 11, the motor 12 and the connecting rods 14 onto the mounting seat 10, and the assembly method is simple and convenient.

[0091] The sensor in the present disclosure can be an optical sensor or a piezoelectric sensor, or other types of sensors. The present disclosure does not limit this.

[0092] The sensor in the present disclosure can be arranged at the inlet of the first intake passage 100. The sensor is used to detect whether there is a foreign object at the inlet of the first intake passage 100.

[0093] When the sensor is an optical sensor, the detection element and the induction element of the sensor are respectively located on both sides of the first intake passage 100. When there is a foreign object at the inlet of the first intake passage 100, the foreign object blocks the induction between the detection element and the induction element. At this time, the sensor detects that there is a foreign object at the inlet of the first intake passage 100, and the sensor emits a signal to cause the first blade 11 to rotate in the second direction to switch to the second state. When there is no foreign object at the inlet of the first intake passage 100, the induction between the detection element and the induction element continues. That is, the sensor detects that there is no foreign object at the inlet of the first intake passage 100, and the sensor emits a signal to cause the first blade 11 to rotate in the first direction to switch to the second state.

[0094] When the sensor is a piezoelectric sensor, the induction element of the sensor is arranged on the bottom wall at the inlet of the first intake passage 100. When there is a foreign object at the inlet of the first intake passage 100, the induction element of the sensor senses an increase in pressure, thereby emitting a signal to cause the first blade 11 to rotate in the second direction to switch to the second state. When there is no foreign object at the inlet of the first intake passage 100, the induction element of the sensor senses that the pressure remains unchanged. That is, the sensor detects that there is no foreign object at the inlet of the first intake passage 100, and the sensor emits a signal to cause the first blade 11 to rotate in the first direction to switch to the second state.

[0095] The sensor in the present disclosure can also be arranged at the rotating shaft 13, the output member 120 or the first blade 11. The sensor is used to detect whether the rotational resistance of the rotating shaft 13, the output member 120 or the first blade 11 in the first direction is greater than a preset value.

[0096] When the sensor detects that the resistance of the rotating shaft 13, the output member 120 or the first blade 11 to rotation in the first direction is greater than a preset value, the sensor sends a signal to make the first blade 11 rotate in the second direction to switch to the second state.

[0097] When the sensor detects that the resistance of the rotating shaft 13, the output member 120 or the first blade 11 rotating in the first direction is less than a preset value, the sensor sends a signal to make the first blade 11 rotate in the first direction to switch to the second state.

[0098] like Figure 8 , Figure 11 and Figure 12 As shown, in some embodiments, the rotating shaft 13 includes a radially extending limiting piece 130. The air intake grille also includes a first limiting block 16 and a second limiting block 17.

[0099] When the sensor detects that the resistance to rotation of the rotating shaft 13, the output member 120 or the first blade 11 in the first direction is greater than a preset value, the sensor sends a signal, and the second limit block 17 cooperates with the limit plate 130 to switch the first blade 11 between the first state and the second state, and the first limit block 16 avoids the movement of the limit plate 130.

[0100] When the sensor detects that the resistance to rotation of the rotating shaft 13, the output member 120 or the first blade 11 in the first direction is less than a preset value, the sensor sends a signal, the first limit block 16 cooperates with the limit plate 130 to switch the first blade 11 between the first state and the second state, and the second limit block 17 avoids the movement of the limit plate 130.

[0101] The present disclosure enables the first blade 11 to accurately switch between the first state and the second state, and between the first direction and the second direction through the cooperation of the limiting piece 130, the first limiting block 16, the second limiting block 17 and the sensor.

[0102] As an optional embodiment, the output member 120 includes a fourth mounting hole 121 coaxially distributed with the output slot. The air intake grille includes two first limit blocks 16 and two second limit blocks 17 circumferentially distributed in the fourth mounting hole 121. The two first limit blocks 16 and the two second limit blocks 17 are cross-distributed with each other.

[0103] like Figure 11As shown, when the sensor detects that the resistance of the rotating shaft 13, the output member 120 or the first blade 11 rotating in the first direction is greater than a preset value, the sensor emits a signal, the two first limiting blocks 16 move out of the fourth mounting hole 121, and the limiting piece 130 moves between the two second limiting blocks 17, and the first blade 11 rotates a distance of 90°. Among them, when it is necessary to open the first air intake passage 100, when the limiting piece 130 rotates 90° in the second direction and contacts one of the second limiting blocks 17 (the solid line position of the limiting piece 130 in the figure), the motor 12 stops rotating to open the first air intake passage 100. When it is necessary to close the first air intake passage 100, when the limiting piece 130 rotates 90° in the first direction and contacts the other second limiting block 17 (the dotted line position of the limiting piece 130 in the figure), the motor 12 stops rotating to close the first air intake passage 100.

[0104] As Figure 12 As shown, when the sensor detects that the resistance of the rotating shaft 13, the output member 120 or the first blade 11 rotating in the first direction is less than a preset value, the sensor emits a signal, the two second limiting blocks 17 move out of the fourth mounting hole 121, and the limiting piece 130 moves between the two first limiting blocks 16, and the first blade 11 rotates a distance of 90°. Among them, when it is necessary to open the first air intake passage 100, when the limiting piece 130 rotates 90° in the first direction and contacts one of the first limiting blocks 16 (the solid line position of the limiting piece 130 in the figure), the motor 12 stops rotating to open the first air intake passage 100. When it is necessary to close the first air intake passage 100, when the limiting piece 130 rotates 90° in the second direction and contacts the other first limiting block 16 (the dotted line position of the limiting piece 130 in the figure), the motor 12 stops rotating to close the first air intake passage 100.

[0105] It should be noted that the way the first limiting block 16 and the second limiting block 17 move out of the fourth mounting hole 121 may include moving out along the axial direction of the fourth mounting hole 121 or moving out along the radial direction of the fourth mounting hole 121. For example, the cooperation of hydraulic pressure and a reset member is used to realize the movement of the first limiting block 16 and the second limiting block 17 in and out of the fourth mounting hole 121 along the radial direction of the fourth mounting hole 121.
