Detailed implementation manners

[0029] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following examples are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] In the related art, for heat exchange of a vehicle, except that air can enter through the ventilation area corresponding to the heat exchange fan on the installation frame, the rest of the area is closed. The installation frame blocks the air volume blown in by the front grille except for the ventilation area. When the vehicle is driving at high speed, the power of the vehicle is high, resulting in serious heat generation. A large amount of air volume is required for heat exchange. However, the air volume entering through the installation frame is fixed and cannot meet the higher heat exchange requirements of the vehicle. Insufficient heat exchange of the vehicle easily leads to overheating.

[0032] In view of this, as Figures 1-9 shown, some embodiments of the present invention provide a vehicle heat exchange frame, including a frame mechanism 1 and a flap 4; an air inlet 2 and a compensation air inlet 3 are provided on the frame mechanism 1. The compensation air inlet 3 is provided on one side of the air inlet 2. The flap 4 is rotatably connected to the side wall of the compensation air inlet 3, and the flap 4 can rotate clockwise by its own gravity to close the compensation air inlet 3. The airflow entering the frame mechanism 1 can drive the flap 4 to rotate counterclockwise against its own gravity to open the compensation air inlet 3.

[0033] In the above embodiment, the frame mechanism 1 can be made of a metal material, such as aluminum alloy, or can be made of a plastic material. Among them, the frame mechanism 1 can be arranged perpendicular to the ground. The frame mechanism 1 can include a frame and connection ears connected to the frame. The frame can be fixed in the vehicle through the connection ears and bolts. An air inlet 2 and a compensation air inlet 3 penetrating the frame mechanism 1 are provided on the frame mechanism 1. The air inlet 2 can be circular. The air inlet 2 can be arranged at the air inlet end of the part of the vehicle that needs heat exchange, so that the heat exchange airflow can enter the part of the vehicle that needs heat exchange through the air inlet 2. When the speed of the vehicle reaches the threshold, the airflow velocity of the airflow entering at the vehicle intake grille is relatively large. The airflow impacts the rectangular compensation air inlet 3 on the frame mechanism 1 and pushes the flap 4, so that the flap 4 rotates relative to the frame mechanism 1, thereby opening the compensation air inlet 3. Airflow can also be provided to the part of the vehicle that needs heat exchange through the compensation air inlet 3, thereby increasing the total flow rate of the airflow flowing to the part of the vehicle that needs heat exchange and improving the heat exchange efficiency. When the speed of the vehicle is below the threshold, the airflow impacts the frame mechanism 1 and flows to the compensation air inlet 3, but the airflow velocity is small and cannot overcome the gravity of the flap 4, so the flap 4 cannot be pushed to rotate relative to the frame mechanism 1, and thus the compensation air inlet 3 cannot be opened. Therefore, the total flow rate of the airflow flowing to the part of the vehicle that needs heat exchange remains unchanged, and the airflow flowing in only through the air inlet 2 can meet the heat exchange requirements of the vehicle.

[0034] Optionally, the threshold of the vehicle speed corresponding to the rotation of the flap 4 relative to the frame mechanism 1 can be set according to requirements. The threshold can be set to 100 km / h or 120 km / h. Exemplarily, the threshold can be set to 120 km / h. When the vehicle is driving on a track, when the speed of the vehicle exceeds 120 km / h, the flap 4 rotates relative to the frame mechanism 1 to increase the heat exchange efficiency.

[0035] Optionally, the heat exchange between the air flow and the vehicle may include cooling the vehicle. For example, when the temperature of the vehicle engine is too high, it is cooled by the air flow. And heating the vehicle, for example, in winter in the north, when the temperature of the battery pack of an electric vehicle is too low, the battery pack of the vehicle is heated by the air flow.

[0036] Optionally, a plurality of compensation air vents 3 may be provided. The plurality of compensation air vents 3 may be arranged at intervals along the circumferential direction of the air inlet 2. A flap 4 is rotatably connected to each compensation air vent 3.

[0037] A vehicle heat exchange frame provided by some embodiments of the present utility model includes a frame mechanism 1 and a flap 4. An air inlet 2 and a compensation air vent 3 are provided on the frame mechanism 1. The flap 4 can rotate clockwise by its own gravity to close the compensation air vent 3, so that when the vehicle is driving at a low speed, the flap 4 will not rotate and cause the compensation air vent 3 to be closed, so that the air flow passing through the air inlet 2 can exchange heat with the vehicle. When the vehicle is driving at a high speed, the air flow entering the frame mechanism 1 can drive the flap 4 to rotate counterclockwise against its own gravity to open the compensation air vent 3, so that the flow rate of the heat exchange air flow entering the vehicle through the frame mechanism 1 is increased through the compensation air vent 3. The technical problem of insufficient heat exchange when the vehicle is driving at a high speed in the prior art is solved, and the technical effect that the flow rate of the heat exchange air flow can be increased by opening the compensation air vent 3 when driving at a high speed, so as to meet the heat exchange of the vehicle, is achieved.

[0038] In an optional embodiment, the flap 4 is rotatably connected to the side wall of the compensation air vent 3 through a rotating shaft 5, and the rotating shaft 5 divides the flap 4 into a first part 6 and a second part 7. The first part 6 is arranged close to the ground, and the second part 7 is arranged away from the ground. The center of gravity of the flap 4 is located within the first part 6.

[0039] In the above embodiment, the axis of the rotating shaft 5 is arranged parallel to the ground. The rotating shaft 5 is cylindrical. The rotating shaft 5 can be made of a metal material. The rotating shaft 5 divides the flap 4 into a first part 6 and a second part 7 along a direction parallel to the ground. Among them, the flap 4 can be rectangular, and the divided first part 6 and second part 7 can also be rectangles with the same length. The center of the flap 4 is located within the first part 6, that is, the center of the flap 4 is located on the side of the rotating shaft 5 facing the ground, so that when the speed of the vehicle does not reach the threshold value, the flap 4 covers the compensation air vent 3 under the action of its own center of gravity, so that the flap 4 can block the compensation air vent 3.

[0040] In an optional embodiment, the contact area between the second part 7 and the air flow is smaller than the contact area between the first part 6 and the air flow.

[0041] In the above embodiment, since the lengths of the first part 6 and the second part 7 are the same, the width of the first part 6 is greater than the width of the second part 7. When the air flow enters the compensation air vent 3 and blows the first part 6 and the second part 7, since the area of the air flow blowing the first part 6 is larger and the area of the air flow blowing the second part 7 is smaller, the force of the air flow pushing the second part 7 is less than the force of the air flow pushing the first part 6. When the difference between the force of the air flow pushing the second part 7 and the force of the air flow pushing the first part 6 can overcome the gravity of the flap 4, the flap 4 starts to flip so that the compensation air vent 3 is opened, enabling the compensation air vent 3 to provide a heat exchange air flow. When the difference between the force of the air flow pushing the second part 7 and the force of the air flow pushing the first part 6 is less than the gravity of the flap 4 that needs to be overcome, the air flow cannot push the flap 4 to rotate, and thus the compensation air vent 3 is in a closed state.

[0042] In an alternative embodiment, a mounting seat 8 is provided on the flap 4. The mounting seat 8 is sleeved on the rotating shaft 5 and is rotatably connected to the rotating shaft 5.

[0043] In the above embodiment, the mounting seat 8 can be connected to the flap 4 by gluing or bonding, or can be integrally formed with the flap 4. The rotating shaft 5 can be set to a cylindrical shape, and the connecting hole in the mounting seat 8 can be sleeved on the rotating shaft 5 so that the mounting seat 8 is rotatably connected to the rotating shaft 5. The flap 4 is rotatably connected to the side wall of the compensation air vent 3 through the mounting seat 8 and the rotating shaft 5, enabling the flap 4 to rotate relative to the side wall of the compensation air vent 3, thereby completing the opening and closing of the compensation air vent 3.

[0044] In an alternative embodiment, a rotating shaft 5 is provided on one of the flap 4 and the side wall of the compensation air vent 3, and a mounting seat 8 is provided on the other. The rotating shaft 5 is rotatably placed in the mounting seat 8.

[0045] In the above embodiment, one rotating shaft 5 can be provided, and one mounting seat 8 can also be provided. The rotating shaft 5 and the mounting seat 8 are close to each other, with one provided on one side wall of the compensation air vent 3 and the other provided on the flap 4. Among them, when the rotating shaft 5 is provided on the side wall of the compensation air vent 3, a mounting seat 8 is provided on the flap 4 close to the rotating shaft 5, and the mounting seat 8 is rotatably connected to the rotating shaft 5. When the rotating shaft 5 is provided on the flap 4, a mounting seat 8 is correspondingly provided on the side wall of the compensation air vent 3, enabling the flap 4 to rotate relative to the side wall of the compensation air vent 3, thereby realizing the opening and closing of the compensation air vent 3.

[0046] In an alternative embodiment, two mounting seats 8 are provided. One of the mounting seats 8 is provided with a mounting hole for sleeving the rotating shaft 5, and the other mounting seat 8 is provided with an opening groove, and a buckle 9 is provided at the opening groove. The rotating shaft 5 is placed in the opening groove and is limited by the buckle 9.

[0047] In the above embodiments, two mounting seats 8 are arranged at intervals on both sides of the flap 4 along a direction parallel to the ground. Correspondingly, two rotating shafts 5 are also provided. The axes of the two rotating shafts 5 coincide and are arranged parallel to the ground. The two rotating shafts 5 are respectively arranged on two opposite inner walls of the compensation air outlet 3 and fixedly connected. Among the two mounting seats 8 on the flap 4, one mounting seat 8 is provided with a mounting hole, and the mounting hole is sleeved on one of the rotating shafts 5. The other mounting seat 8 is provided with an opening groove, and the cross-section of the opening groove is semicircular. The opening groove covers the other rotating shaft 5, and the opening groove is slidably connected to the rotating shaft 5. A buckle 9 is arranged on the opening groove. The buckle 9 is arc-shaped and can be made of an elastic material. During the process of the rotating shaft 5 being inserted into the opening groove, the rotating shaft 5 first presses the buckle 9 to deform the buckle 9, so that the opening of the buckle 9 is greater than or equal to the diameter of the rotating shaft 5, enabling the rotating shaft 5 to slide into the opening groove. Then, after the rotating shaft 5 enters the opening groove, the buckle 9 restores its deformation, so that the width of the opening of the buckle 9 is less than the diameter of the rotating shaft 5, enabling the buckle 9 to cooperate with the opening groove to fix the rotating shaft 5.

[0048] In an alternative embodiment, a boss 10 extends outward from one end of the compensation air outlet 3 close to the ground, and one end of the flap 4 close to the ground abuts against the boss 10, so that the flap 4 is inclined.

[0049] In the above embodiments, a boss 10 is provided at the air outlet end of the compensation air outlet 3. The protruding direction of the boss 10 can extend along the air flow direction. The boss 10 can be provided at one end of the compensation air outlet 3 close to the ground, so that one end of the flap 4 close to the ground can abut against the boss 10, and the flap 4 is arranged at an angle relative to the surface of the frame mechanism 1. The boss 10 can also extend along the circumferential direction of the compensation air outlet 3. When the boss 10 extends along the circumferential direction of the compensation air outlet 3, the end of the boss 10 away from the frame mechanism 1 is set as a plane, so that the flap 4 can adhere to the boss 10, so that the boss 10 can abut against the flap 4 along the circumferential direction of the compensation air outlet 3, so that the flap 4 is fixed, and at the same time, the compensation air outlet 3 can be sealed by the flap.

[0050] Among them, the inclined flap 4 can be pressed tightly against the boss 10 under the action of gravity, so that the air flow that does not reach the predetermined speed can be prevented from blowing the flap 4, and at the same time, the flap 4 can be pressed tightly against the boss 10 to prevent the flap 4 from frequently hitting the boss 10 during driving to generate noise.

[0051] In an alternative embodiment, a first limiting portion 11 is provided on the flap 4, and a second limiting portion 12 is provided on the side wall of the compensation air outlet 3. When the flap 4 rotates a preset angle relative to the compensation air outlet 3, the first limiting portion 11 and the second limiting portion 12 abut against each other.

[0052] In the above embodiments, the first limiting portion 11 can be connected to the flap 4 by welding or bonding, or can be integrally formed with the flap 4 by pouring. The first limiting portion 11 can be arranged on one side of the side wall of the flap 4 close to the compensation air outlet 3. The first limiting portion 11 can be arranged on the mounting seat 8. The first limiting portion 11 can be set as a protrusion. The thickness of the first limiting portion 11 can be arranged to increase along the direction close to the ground when the flap 4 closes the compensation air outlet 3, so that the flap 4 can drive the first limiting portion 11 to start rotating through the mounting seat 8. Further, a second limiting portion 12 is arranged on the side wall of the compensation air outlet 3 close to the first limiting portion 11. The second limiting portion 12 extends towards the side wall direction of the other side of the compensation air outlet 3. The second limiting portion 12 can be in a sheet shape. The second limiting portion 12 is arranged on the rotation path of the first limiting portion 11. When the flap 4 drives the first limiting portion 11 to rotate, when the flap 4 rotates to a preset angle, the first limiting portion 11 abuts against the second limiting portion 12, so that the flap 4 cannot continue to rotate, thereby limiting the rotation angle of the flap 4. Wherein, when the flap 4 rotates relative to the compensation air outlet 3 to the preset angle, the compensation air outlet 3 is opened to the maximum ventilation area, that is, at this time, the air volume passing through the compensation air outlet 3 is the largest. At this time, the first part 6 and the second part 7 arranged on the same plane can be parallel to the ground or arranged at an angle to the ground, and under the push of the air flow, the first limiting portion 11 is pressed against the second limiting portion 12, avoiding the rotation angle of the flap 4 being too large, resulting in affecting the air intake volume of the compensation air outlet 3.

[0053] Some embodiments of the present utility model further provide a vehicle heat exchange device, including a heat exchange fan 13, a heat exchanger 14 and a vehicle heat exchange frame; the heat exchange fan 13 is installed in the air inlet 2 and is rotatably connected to the frame mechanism 1; the heat exchanger 14 is installed on the frame mechanism 1 and is arranged opposite to the heat exchange fan 13.

[0054] In the above embodiments, the heat exchange fan 13 is arranged in the air inlet 2. The air inlet 2 is circular and provided with a grille. The heat exchange fan 13 is connected to the grille through a motor. The heat exchange fan 13 can accelerate the air flow passing through the air inlet 2, thereby increasing the flow rate of the air flow entering the vehicle, thereby increasing the heat exchange area. Further, a heat exchanger 14 is also arranged at the air inlet end of the frame mechanism 1. The heat exchanger 14 includes a plurality of heat exchange fins arranged parallel to each other and evenly. The air flow enters through the gaps between the heat exchange fins and blows towards the frame mechanism 1, so that the air flow is cooled.

[0055] Wherein, the principle of the heat exchanger 14 will not be elaborated here.

[0056] Some embodiments of the present utility model further provide a vehicle, including the vehicle heat exchange device.

[0057] In the above embodiments, the vehicle includes an engine compartment, an engine, and an intake grille. The vehicle heat exchange device can be disposed in the engine compartment and between the intake grille and the engine. The vehicle heat exchange device can cool the air flow entering from the intake grille and blow it towards the engine at the rear through the heat exchange fan 13, so that the engine is cooled to prevent the engine from overheating and malfunctioning.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
