Description

Technical Field

[0001] This utility model belongs to the field of radiator fixing technology, specifically relating to a fixing connection structure for an engineering vehicle radiator. Background Technology

[0002] The radiator is a core component of the thermal management system of engineering vehicles, used to exchange heat between the vehicle's coolant, water, or air and the outside air, thereby reducing the temperature of these heat transfer media. Currently, when radiators are fixed in vehicles, a protruding block is set on the bottom of the radiator body, and a groove corresponding to the protruding block is set on the vehicle frame. Then, the protruding block of the radiator is directly connected to the frame with bolts to fix the radiator. When the radiator is connected, the vibration generated by the vehicle body is easily transmitted to the radiator. The vibration reduction effect is not good if the rubber vibration damping pads between the radiator and the frame or between the bolts are simply used. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a fixed connection structure for radiators of engineering vehicles to improve the stability of radiators.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A fixed connection structure for a radiator of an engineering vehicle includes a first U-shaped frame, a second U-shaped frame connected to the first U-shaped frame, a buffer pad located on the second U-shaped frame, and a first connecting bolt for connecting to the radiator. The first U-shaped frame includes a first intermediate plate and two first side plates connected to the first intermediate plate. The second U-shaped frame includes a second intermediate plate and two second side plates connected to the second intermediate plate. The second U-shaped frame is located between the two first side plates. The second side plates are connected to the first side plates by second connecting bolts. The second intermediate plate is provided with a second through hole corresponding to the first connecting bolt.

[0006] Furthermore, the buffer pad includes a downward first protrusion, and the buffer pad is provided with a third through hole corresponding to the heat sink protrusion.

[0007] Furthermore, the second intermediate plate has a downward protrusion in the middle to form a second protrusion, and the second protrusion has a first groove corresponding to the first protrusion.

[0008] Furthermore, the first intermediate plate is provided with a first through hole corresponding to the second protrusion.

[0009] Furthermore, the lower end face of the second protrusion is higher than the lower end face of the first side plate.

[0010] Furthermore, there are two second connecting bolts, which are arranged symmetrically.

[0011] Furthermore, the first side plate is longer than the second side plate.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0013] 1. A second U-shaped frame can be detachably connected to the first U-shaped frame. The radiator is connected to the second U-shaped frame and not directly connected to the first U-shaped frame. The second U-shaped frame itself plays a certain role in vibration reduction.

[0014] 2. A second U-shaped frame and a buffer pad are provided. The buffer pad has a first protrusion and a third through hole. The second U-shaped frame has a first groove corresponding to the first protrusion. After the second U-shaped frame is connected to the radiator by the first connecting bolt, the buffer pad and the second U-shaped frame can support the radiator well and improve the vibration reduction effect of the radiator.

[0015] 3. The second side plate of the second U-shaped frame is connected to the first side plate of the first U-shaped frame through the second connecting bolt. The second U-shaped frame raises the radiator in height, which can ensure the length of the radiator protrusion while preventing the radiator protrusion from exceeding the first U-shaped frame, thereby reducing the impact of the radiator protrusion on the structural settings of other parts of the vehicle.

[0023] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0024] like Figure 1 , Figure 6 and Figure 7 As shown in the figure, the radiator fixing connection structure of this embodiment is used to fix the radiator 9. The radiator 9 has an inlet pipe and an outlet pipe (not shown in the figure) at the bottom. The cooling medium flows in an inverted U-shape, entering from the bottom inlet pipe, passing upward through the cooling pipe, then reaching the top and flowing downward through the other half of the cooling pipe, and finally exiting from the outlet pipe. The bottom of the radiator 9 has two protruding blocks, which are welded to the main body of the radiator 9. The protruding blocks include a boss 91 and a protruding post 92. The boss 91 is a circular platform, and the protruding post 92 has an internal thread 921 at its center.

[0025] like Figure 1 and Figure 2 As shown, the fixed connection structure of this embodiment includes a first U-shaped frame 1, a second U-shaped frame 2, a buffer pad 3, a first connecting bolt 4, and a second connecting bolt 5. The first U-shaped frame 1 is generally U-shaped. The first U-shaped frame 1 includes a first intermediate plate 11 and two first side plates 12. The two first side plates 12 are of equal length and are connected to the two ends of the first intermediate plate 11 respectively. In this embodiment, the two first side plates 12 and the first intermediate plate 11 are integrally formed. The first U-shaped frame 1 is made of steel plate.

[0026] like Figure 1 and Figure 4 As shown, the buffer pad 3 is made of rubber. The buffer pad 3 is circular in shape, and its outer diameter is the same as that of the boss 91, so as to support the boss 91. The buffer pad 3 includes a downward first protrusion 31. The buffer pad 3 is provided with a third through hole 301, which runs through the buffer pad 3 from top to bottom. The third through hole 301 corresponds to the protruding post 92 so as to accommodate the protruding post 92.

[0027] like Figure 1 , Figure 3 and Figure 5As shown, the second U-shaped frame 2 is also U-shaped as a whole. The second U-shaped frame 2 is located between the two first side plates 12. The second U-shaped frame 2 includes a second intermediate plate 21 and two second side plates 22. The two second side plates 22 are of equal length and shorter than the length of the first side plates 12. The two second side plates 22 are connected to the two ends of the second intermediate plate 21 respectively. In this embodiment, the two second side plates 22 and the second intermediate plate 21 are integrally formed. The second U-shaped frame 2 is made of steel plate. The second intermediate plate 21 has a downward protrusion in the middle to form a second protrusion 211. The second protrusion 211 is provided with a first groove 202. The first groove 202 corresponds to the shape of the first protrusion 31 so as to accommodate the first protrusion 31. The first intermediate plate 11 is provided with a first through hole 101, which corresponds to the second protrusion 211. The inner diameter of the first through hole 101 is larger than the outer diameter of the second protrusion 211. When the first U-shaped frame 1 is connected to the second U-shaped frame 2, the second protrusion 211 is located inside the first through hole 101. The height of the lower end face of the second protrusion 211 is higher than the height of the lower end face of the first side plate 12. A gap is left between the straight plate portion of the second intermediate plate 21 and the first intermediate plate 11.

[0028] like Figure 1 , Figure 3 and Figure 6 As shown, the external thread of the first connecting bolt 4 corresponds to the internal thread 921 of the protruding post 92. The second intermediate plate 21 is provided with a second through hole 201, which corresponds to the first connecting bolt 4. The first connecting bolt 4 passes through the second through hole 201 and the third through hole 301 on the buffer pad 3 and then connects to the protruding post 92, thereby connecting the second U-shaped frame 2 to the radiator 9. The upper side of the radiator 9 is also connected to the fixed frame body by a rubber damping pad and bolts. The fixed frame body can be integrally connected with the first U-shaped frame 1 or it can be a separate connecting frame. The first side plate 12 is provided with a first side through hole, and the second side plate 22 is provided with a second side through hole. The second side through hole corresponds to the position of the first side through hole. The two second side plates 22 are respectively connected to the two first side plates 12 by second connecting bolts 5. The two second connecting bolts 5 are symmetrically arranged. The second connecting bolts 5 pass through the first side through hole and the second side through hole and then connect to the second connecting nut. The two second connecting nuts are used to connect and fasten the second U-shaped frame 2 and the first U-shaped frame 1.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
