In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.
[0056] Combine the following Figure 1-Figure 8 A cooling mechanism provided by the present application is described in detail.
[0057] In this embodiment, a cooling mechanism is provided, which includes a wind shield 1, an intercooler 2, a frame assembly 3, a radiator 4 and a baffle 5; wherein the wind shield 1, the intercooler 2, the radiator 4 and the baffle 5 are integrated together along the thickness direction of the cooling mechanism and through the frame assembly 3; in actual use, after antifreeze is added to the radiator 4 and during the consumption of the antifreeze in the radiator 4, the center of gravity of the cooling mechanism will change. When the center of gravity of the cooling mechanism changes, the circular rubber pad used in the process of connecting the cooling mechanism with other mechanisms will be worn.
[0058] Specifically, in order to prevent the center of gravity of the cooling mechanism from shifting, the following derivation process is used: Figure 4 As shown, the assembly point 6 of the cooling mechanism during the assembly process with other mechanisms is given; combined Figure 3As shown, the weight of the wind shield 1 is set to G1, and the distance from the center of gravity to the assembly point 6 is L1; the weight of the intercooler 2 is set to G2, and the distance from the center of gravity to the assembly point 6 is L2; the weight of the frame assembly 3 is set to G3, and the distance from the center of gravity to the assembly point 6 is L3; the weight of the radiator 4 is set to G4, and the distance from the center of gravity to the assembly point 6 is L4; the weight of the baffle 5 is set to G5, and the distance from the center of gravity to the assembly point 6 is L5. According to the principle of moment balance, there is the following relationship: G1*L1+G2*L2=G3*L3+G5*L5+G4*L4. In this relationship, only the weight of the radiator 4 changes with the addition and consumption of antifreeze, and other quantities are fixed values. Therefore, how to ensure that the value of G4*L4 of the radiator 4 remains unchanged during the addition and consumption of antifreeze is the conception of the present application, and the present application is born accordingly.
[0059] Specifically, the radiator 4 includes a main body 9, an upper water chamber 10 and a lower water chamber 11; the upper water chamber 10 is arranged at one end of the main body 9 along the height direction through an upper guard plate assembly 12, and the lower water chamber 11 is arranged at the other end of the main body 9 along the height direction through a lower guard plate assembly 13; the cooling mechanism also includes a first limiting member and a second limiting member.
[0060] Furthermore, the first limiting member is disposed between the main body 9 and the upper guard plate assembly 12 , and the second limiting member is disposed between the main body 9 and the lower guard plate assembly 13 .
[0061] In actual application, when antifreeze liquid is injected into the radiator 4 so that the weight of the radiator 4 is greater than the preset weight, the radiator 4 can move along the first direction. Figure 3 For example, it refers to the movement in the lower right direction, that is, when the weight of the radiator 4 is greater than the preset value, L4 will become smaller, so as to ensure that the value of G4*L4 remains unchanged, thereby ensuring that the center of gravity of the cooling mechanism does not shift; when the antifreeze liquid is discharged from the radiator 4 so that the weight of the radiator 4 is less than the preset weight, the radiator 4 can move in the second direction, and the second direction here is Figure 3 For example, it refers to the upper left movement, that is, when the weight of the radiator 4 is less than the preset value, L4 will become larger, thus ensuring that the value of G4*L4 remains unchanged, thereby ensuring that the center of gravity of the cooling mechanism does not shift. In summary, no matter whether antifreeze is injected into the radiator 4 or the antifreeze is discharged from the radiator 4, the overall center of gravity of the cooling mechanism will not shift, so there will be no wear on the circular rubber pad, thereby ensuring the integrity of the circular rubber pad.
[0062] In this embodiment, combined Figure 5 , Figure 6 as well as Figure 7 As shown, the first limiting member includes a first limiting block 14, a second limiting block 15, a first limiting plate 16 and a second limiting plate.
[0063] Specifically, the first limit block 14 and the second limit block 15 are respectively arranged on both sides of the width direction of the upper water chamber 10, and the width direction of the upper water chamber 10 here refers to Figure 3 The first stopper 14 is a gradually contracting structure from the upper water chamber 10 to the lower water chamber 11, and the second stopper 15 is a gradually expanding structure from the upper water chamber 10 to the lower water chamber 11. A first stopper plate 16 that can abut against the first stopper 14 extends from one end of the upper guard plate assembly 12 in the width direction toward the lower guard plate assembly 13, and a second stopper plate that can abut against the second stopper 15 extends from the other end of the upper guard plate assembly 12 in the width direction toward the lower guard plate assembly 13.
[0064] More specifically, the first limit block 14 is in a semi-teardrop shape consisting of a first arc surface 18, a first inclined surface 19 and a first plane 20, and the first plane 20 is attached to the upper water chamber 10; the second limit block 15 is in a right-angled triangle shape and the first right-angled surface 21 is attached to the upper water chamber 10.
[0065] More specifically, the first limit plate 16 includes a first flange 22 and a second flange 23; the first flange 22 is connected to the upper guard plate assembly 12 at 90°; the first flange 22 is connected to the second flange 23 at a first preset angle;
[0066] The first inclined surface 19 and the first plane 20 form a second preset angle; the first preset angle is complementary to the second preset angle, that is, the second flange 23 is arranged parallel to the first inclined surface 19. The second flange 23 abuts against the middle of the first plane 20. Preferably, the first preset angle is 150°, and the second preset angle is 30°.
[0067] More specifically, the second limiting plate includes a third flange 24 ; the third flange 24 is connected to the upper guard plate assembly 12 at 90° and extends toward the first right-angled surface 21 of the second limiting block 15 and abuts against the middle of the first right-angled surface 21 .
[0068] In this embodiment, the second limiting member includes a third limiting block 25 , a fourth limiting block 26 , a third limiting plate and a fourth limiting plate 28 .
[0069] Specifically, the third limit block 25 and the fourth limit block 26 are respectively arranged on both sides of the width direction of the lower water chamber 11. The third limit block 25 has a gradually contracting structure along the direction from the upper water chamber 10 to the lower water chamber 11, and the fourth limit block 26 has a gradually expanding structure along the direction from the upper water chamber 10 to the lower water chamber 11.
[0070] Specifically, a third limit plate capable of abutting against the third limit block 25 extends from one end of the lower guard plate assembly 13 in the width direction toward the upper guard plate assembly 12, and a fourth limit plate 28 capable of abutting against the fourth limit block 26 extends from the other end of the lower guard plate assembly 13 in the width direction toward the upper guard plate assembly 12.
[0071] More specifically, the fourth limit block 26 is in a semi-teardrop shape consisting of a second arc surface 29, a second inclined surface 30 and a second plane 31, and the second plane 31 is attached to the lower water chamber 11; the third limit block 25 is in a right-angled triangle shape and the second right-angled surface 32 is attached to the lower water chamber 11.
[0072] More specifically, the fourth limit plate 28 includes a fifth flange 33 and a sixth flange 34. The fifth flange 33 is connected to the lower guard plate assembly 13 at 90 degrees; the fifth flange 33 and the sixth flange 34 are connected at a third preset angle; the second inclined surface 30 and the second plane 31 form a fourth preset angle; the third preset angle is complementary to the fourth preset angle; and the fourth flange abuts against the middle of the second plane 31.
[0073] More specifically, the fifth limiting plate includes a seventh flange 35 , which is connected to the lower guard plate assembly 13 at 90° and extends toward the right-angle surface of the third limiting block 25 and abuts against the middle of the right-angle surface of the second limiting block 15 .
[0074] Furthermore, a cushion block 36 is disposed between the lower guard plate assembly 13 and the lower water chamber 11 , and the third flange 24 is disposed on the cushion block 36 .
[0075] In summary, in the actual use process of this application, combined with Figure 3 As shown, when antifreeze is added to the radiator 4, its weight G4 increases, compressing the cushion block 36, and the radiator 4 moves downward as a whole. During the downward movement of the radiator 4, the third limit plate on the lower water chamber 11 will limit the downward movement of the third limit block 25, and the first limit plate 16 on the upper water chamber 10 will limit the downward movement of the first limit block 14, so that when the radiator 4 moves downward as a whole, it moves to the right at the same time. In this way, the distance L4 from the center of gravity to the assembly point 6 is reduced; when the antifreeze is reduced, the force on the cushion block 36 is reduced, the compression amount is reduced, and the radiator 4 moves upward as a whole. During the upward movement of the radiator 4, the second limit plate will limit the second limit block 15, and the fourth limit plate 28 will limit the fourth limit block 26, so that when the radiator 4 moves upward as a whole, it moves to the left at the same time, and the distance L4 from the center of gravity to the assembly point 6 increases; it is worth noting that: when the radiator 4 moves upward or downward, the distance L4 from the center of gravity to the assembly point 6 decreases or increases. Calculation and design based on actual conditions can ensure that G4*L4 is a constant.
[0076] In addition, more specifically, the first inclined surface 19 , the second inclined surface 30 , the inclined surface of the second limiting plate and the inclined surface of the third limiting plate are all arranged in parallel to ensure that the heat sink 4 is vertical as a whole when it moves left and right.
[0077] In addition, graphite powder is applied between the pad 36 and the lower guard plate assembly 13 to facilitate the pad 36 and the lower water chamber 11 to move forward and backward in the lower guard plate assembly 13. The lower water chamber 11 has a circular protrusion, which plays a positioning role when assembled with the pad 36, and also facilitates the pad 36 and the lower water chamber 11 to move forward and backward in the lower guard plate assembly 13.
[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
