Description

Technical Field

[0001] The invention relates to the technical field of radiator box installation, in particular to a radiator box for a new energy vehicle. Background Art

[0002] In cold weather, if the cooling system of new energy vehicles works normally, the heat generated by the motor will be quickly dissipated. The main function of the radiator is to transfer heat to the radiator surface through the circulation of coolant. Under normal circumstances, the radiator's cooling fins exchange heat with the cold air, and the heat is taken away by the cold air. However, in cold weather, if the heat loss of the radiator is too fast, the motor of the new energy vehicle will not be able to start quickly. At the same time, during the driving of new energy vehicles, foreign objects such as impurities will enter the vents, causing the vents to be blocked, reducing the air flow, which in turn affects the outside air entering the radiator, and causes the radiator to be damaged due to poor air circulation. In addition, when the radiator is installed on a new energy vehicle without a protective shell, when encountering bumpy road conditions or minor collisions, the radiator will be hit and damaged. At the same time, in the case of an existing protective shell, when replacing or repairing the radiator, the protective shell and the radiator need to be complicatedly disassembled, thereby extending the working steps required to replace the radiator.

At the same time, the protective shell can effectively prevent rain, dust, mud and sand from entering the radiator. During the driving of the new energy vehicle, if it suffers a slight scratch or collision, the protective shell can absorb and disperse the impact force to reduce damage to the radiator.

[0025] The quick installation assembly also includes a sliding rod 26 symmetrically slidably connected to the bottom of the fixed plate 20, and each connecting column 25 is rotatably connected to the sliding rod 26 at one end away from the rotating handle 22. Two connecting rods three 27 are symmetrically fixedly connected to the top of each sliding rod 26. The connecting rod three 27 is slidably adapted to the inside of the sliding opening 21, and a rubber pad 28 is fixedly connected between every two connecting rods three 27. A plurality of threaded holes 29 are annularly opened at the bottom of the protective shell 1, and a threaded rod 30 is threadedly connected to the internal threads of the threaded holes 29.

[0026] The above implementation works as follows: The initialization steps are as follows: The staff opens the top cover of the protective shell 1 , and puts the heat sink 2 into the inner cavity of the protective shell 1 , so that the protective shell 1 and the top of the fixing plate 20 are in contact with each other.

[0027] The working steps are as follows: The working steps of the opening and closing components are as follows: After the electric telescopic rod 5 is energized, it begins to extend vertically downward, thereby the electric telescopic rod 5 drives the fixed rod 6 to move vertically downward, so that the fixed rod 6 pushes the connecting rod 1 7 to move downward in the vertical direction, so that the connecting rod 1 7 pushes the connecting rod 2 8 to move synchronously in the vertical direction, so that the connecting rod 2 8 drives the multiple rotating rods 10 to rotate counterclockwise with the connection point with the rotating column 11 as the axis, so that the connecting rod 2 8 is also subjected to the reaction force of the multiple rotating rods 10 to move in the direction away from the rotating rod 10, so the setting of the connecting rod 1 7 avoids the situation that the connecting rod 2 8 is stuck when making an arc movement, so the rotating rod 10 drives the rotating column 11 to rotate counterclockwise with the connection point between the rotating column 11 and the fixed frame 9 as the center, so that the multiple rotating columns 11 drive the multiple opening and closing plates 12 to swing in the direction close to the top of the protective shell 1 at the same time, so that the multiple opening and closing plates 12 are all swung from the horizontal horizontal placement to the vertical longitudinal placement, so that the multiple opening and closing plates 12 form a closed plate.

[0028] The working steps of the scraping component are as follows: As mentioned above, when the electric telescopic rod 5 is extended vertically downward, the electric telescopic rod 5 drives the fixed rod 6 to move vertically downward, so that the fixed rod 6 pushes the rotating rod 2 13 to move synchronously, so that the rotating rod 2 13 drives the rotating disk 14 to rotate counterclockwise, so that the rotating disk 14 makes the rotating rod 2 13 move in an arc, and the counterclockwise rotation of the rotating disk 14 is on the sleeve 15, so that the strip hole 16 opened on the rotating disk 14 passes through its inner wall, pushing the rotating rod 3 17 to slide inside the strip hole 16, so that the rotating rod 3 17 pushes the arc-shaped rubber block 18 to move axially close to the center of the heat dissipation vent 4 with the center of the fixed cylinder 19 as the axial direction, so the five The arc-shaped rubber blocks 18 move toward the center of the heat dissipation vent 4 at the same time, so that the five arc surfaces of the five arc-shaped rubber blocks 18 close to the strip hole 16 form a circle, thereby closing the surface of the heat dissipation vent 4. When the fan on the heat dissipation vent 4 on the side away from the rotating disk 14 is no longer working, the staff can drive the electric telescopic rod 5 to extend and retract periodically. When the electric telescopic rod 5 retracts, the above working steps can be repeated in reverse. Therefore, when the electric telescopic rod 5 performs multiple periodic extensions and retractions, the five arc-shaped rubber blocks 18 continuously scrape the surface of the heat dissipation vent 4.

[0029] The scraping component is provided to prevent dust and impurities from accumulating on the surface of the heat dissipation vent 4, thereby ensuring the unobstructed heat dissipation vent 4 and allowing cold air to smoothly enter the heat dissipation box 2, thereby avoiding impurities from entering the heat dissipation vent 4 and causing blockage during the driving of the new energy vehicle, thereby avoiding damage caused by excessive temperature of the heat dissipation box 2 due to blockage of the heat dissipation vent 4.

[0030] Through the cooperation between the opening and closing components and the scraping components, the protective shell 1 can be closed in cold weather, so that the heat sink 2 is in a closed environment, thus preventing heat from being dissipated to the external environment too quickly in cold weather. The heat generated by the operation of the new energy vehicle will be concentrated around components such as the heater tank in the car, thereby achieving a rapid temperature increase. At the same time, properly adjusting the opening and closing gap of the opening and closing plate 12 in cold weather can also avoid the situation where the temperature loses too quickly due to the large gap of the opening and closing plate 12 in cold weather, and can avoid the situation where external cold air quickly enters the contact between cold and hot air to form condensation beads.

[0031] The steps for quick installation of components are as follows: As in the initialization step, when the heat sink 2 and the upper surface of the fixing plate 20 are in conflict with each other, the staff first screws the threaded rod 30 out of the threaded hole 29, so that the rotation of the handle 24 is no longer restricted. Then the staff manually holds the handle 24 and twists the handle 24 clockwise, so that the handle 24 drives the rotating rod 4 23 to rotate clockwise. At this time, the rotation of the rotating rod 4 23 drives the rotating handle 22 to rotate clockwise with the connection between the rotating handle 22 and the fixing plate 20 as the center. Therefore, the rotating handle 22 pulls the two connecting columns 25 to make the two sliding rods 26 move to The rotating rod four 23 slides on the fixed plate 20 near the center of the circle, so that the two sliding rods 26 are constantly approaching each other, and the two sliding rods 26 drive the connecting rod three 27 to also constantly approach and slide on the sliding opening 21. When the connecting rod three 27 drives the rubber pad 28 thereon to hit the side wall of the heat sink 2, the staff screws the threaded rod 30 into one of the threaded holes 29 at this time, so that the threaded rod 30 hits the handle 24, so that the handle 24 no longer reverses, so that the two rubber pads 28 can hit the heat sink 2, thereby improving the stability of the heat sink 2.

[0032] By setting up the quick installation components and the protective shell 1, the installer can use the quick installation components to quickly install the heat sink 2 at the appropriate position, and ensure that the relative position between the heat sink 2 and other components is correct, and can quickly fix the heat sink 2 inside the protective shell 1, making the installation of the heat sink 2 more convenient and accurate. At the same time, the protective shell 1 can effectively prevent rain, dust, mud and sand from entering the heat sink 2, and during the driving of the new energy vehicle, if it suffers a slight scratch or collision, the protective shell 1 can absorb and disperse the impact force to reduce the damage to the heat sink 2.
