[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] A fan assembly structure for a new energy vehicle, as Figure 1 shown, includes an outer frame 1 and mounting holes opened on the outer frame 1. A fan housing 2 detachably connected thereto is arranged in the mounting holes. A plurality of positioning blocks 14 distributed in a circumferential array are fixedly connected to the outer wall of the fan housing 2. A plurality of card slots for inserting the positioning blocks 14 are opened on the inner wall of the mounting holes. When the fan housing 2 is inserted and installed in the mounting block, the positioning blocks 14 will be inserted into the card slots one by one, making the installation of the fan housing 2 more stable.

[0021] A receiving table 3 for placing the fan housing 2 is fixedly connected to the side wall of the outer frame 1. The upper end surface of the receiving table 3 is flush with the inner wall of the mounting hole. A clamping plate one 4 and two symmetrically distributed clamping plates two 5 are slidably connected to the side wall of the outer frame 1. The clamping plate one 4 is located above the mounting hole and is on the same straight line as the receiving table 3 in the vertical direction. The two clamping plates two 5 are respectively located on the outermost two sides of the mounting hole. The clamping plate one 4, the clamping plates two 5 and the receiving table 3 are all arc-shaped. The arcs of the clamping plate one 4, the clamping plates two 5 and the receiving table 3 coincide with the arc of the surface of the fan housing 2.

[0022] A driving device for driving the clamping plate one 4 and the clamping plates two 5 to clamp synchronously is arranged on the side wall of the outer frame 1.

[0023] The driving device includes two symmetrically distributed fixing plates 6, both sides of the fixing plates 6 are fixedly connected to the side walls of the outer frame 1, a bidirectional lead screw 7 is rotatably connected between the two sides of the fixing plates 6, and a motor 8 for driving the bidirectional lead screw 7 to rotate is fixedly installed on the side wall of one side of the fixing plate 6. Nut seats 9 are sleeved on both the left-handed thread section and the right-handed thread section of the bidirectional lead screw 7. Driven rods 10 are fixedly connected to the lower end surfaces of the two sides of the nut seats 9, and the two sides of the driven rods 10 are respectively fixedly connected to the two sides of the clamping plates two 5. The bidirectional lead screw 7 is located above the clamping plate one 4, and a linkage device is arranged between the two sides of the nut seats 9 and the clamping plate one 4.

[0024] The linkage device includes a linkage block 11 fixedly connected to the upper end surface of the clamping plate one 4. Rotating rods 12 with one end rotatably connected thereto are arranged on the side walls of the two sides of the nut seats 9, and the other ends of the two sides of the rotating rods 12 are rotatably connected to the side wall of the linkage block 11.

[0025] A limiting rod 13 is fixedly connected between the two sides of the fixing plates 6. Limiting grooves for the limiting rod 13 to pass through are opened on the two sides of the nut seats 9. During the process of the nut seat 9 moving along with the rotation of the lead screw, the nut seat 9 will move along the limiting rod 13, making the nut seat 9 more stable during the moving process.

[0026] Working principle: When the fan housing 2 needs to be installed on the outer frame body, first insert the end of the fan housing 2 into the installation hole, place the fan housing 2 on the receiving platform 3, and then drive the bidirectional lead screw 7 to rotate through the motor 8. The bidirectional lead screw 7 drives the nut seats 9 on both sides to approach each other, so that the clamping plates two 5 on both sides approach each other under the drive of the driven rods 10 until the fan housing 2 between the two sides of the clamping plates two 5 is clamped. At the same time, during the process of the two sides of the nut seats 9 approaching each other, the rotating rods on both sides will rotate and close under the drive of the two sides of the nut seats 9, driving the linkage block 11 and the clamping plate one 4 to move downward until the clamping plate one 4 also presses tightly above the fan housing 2. Turn off the motor 8 to make the clamping plate one 4 and the clamping plate two 5 stay in the current position, realizing the fixation of the fan housing 2 from four directions, completing the installation of the fan, without the need to rely on external tools, and the clamping plate one 4 and the clamping plate two 5 are linked and clamped, which is convenient to operate.

[0027] When the fan needs to be disassembled, drive the bidirectional lead screw 7 to rotate in the opposite direction through the motor 8, drive the nut seats 9 on both sides to move away from each other, drive the clamping plates on both sides to loosen the fan housing 2 through the driven rods 10. At the same time, the nut seats 9 on both sides can drive the rotating rods 12 to rotate outward and open, drive the clamping plate one 4 to move upward through the linkage block 11 to loosen the fan housing 2, and then the fan housing 2 can be smoothly removed from the installation hole, completing the disassembly of the fan, which is convenient to operate.

[0028] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
