Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning systems, specifically relating to a structure for quickly changing the installation height of an automotive air conditioning condenser fan. Background Technology

[0002] With the development of society, cars have become a common household item, and as an essential part of cars, the demand for car air conditioning remains high. The working principle of car air conditioning is to replace air by operating a fan installed in the air conditioner. The car air conditioning fan replaces air by operating a fan.

[0003] Currently, due to varying customer requirements regarding installation space and performance, the height of automotive air conditioning fans often differs, resulting in a height difference between the automotive fan and the impeller cover, leading to poor versatility.

[0004] Therefore, to address the issue that existing automotive air conditioning condenser fans often have different heights due to differences in installation space and performance, resulting in a height difference between the condenser fan and the impeller cover, a quick-adjustment structure for the installation height of automotive air conditioning condenser fans is designed. This structure utilizes stackable mounting brackets between the impeller cover and the fan to quickly adjust the height between them. Utility Model Content

[0005] To overcome the problem that existing automotive air conditioning condenser fans have different heights and there is an installation height difference between them and the impeller cover.

[0007] Preferably, by adding an installation bracket between the impeller cover and the fan, and providing a positioning groove at the bottom of the positioning column that matches the positioning boss on the top of the positioning column and the positioning boss on the impeller cover, the installation brackets can be stacked. Multiple installation brackets can be added between the impeller cover and the fan according to the installation height difference between the impeller cover and the fan, thereby reducing the height difference.

[0008] Preferably, the positioning boss on the positioning post has a first anchoring hole that penetrates the positioning post, and the positioning boss on the impeller cover has a second anchoring hole that matches the first anchoring hole. The first and second anchoring holes have the same diameter, which makes it easy to fix them with an anchoring post and avoids displacement.

[0009] Preferably, a support plate is fixedly connected to the bottom of the fan. The support plate has a third anchor hole that is concentric with the first and second anchor holes. Screws are screwed into the first, second, and third anchor holes. The fan, impeller cover, and several mounting brackets sandwiched in the middle can be fixed together by the screws that serve as anchoring columns.

[0010] Preferably, the car has a storage compartment inside, in which the fan installed behind the impeller cover is installed. The storage compartment can provide installation space for the fan, the power supply behind the fan, and other components of the air conditioner. At the same time, the storage compartment can also protect these components, prevent them from being affected by the external environment, and extend their service life.

[0011] Preferably, a square No. 1 insert is inserted into the storage slot and fitted onto the outside of the impeller cover.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 - Figure 6 This utility model provides an embodiment: a quick-conversion structure for the installation height of an automotive air conditioning condenser fan 1 includes a fan 1, an impeller cover 2, a mounting bracket 3, positioning posts 4, positioning bosses 5, and positioning grooves 6; an impeller cover 2 is provided on the front side of the fan 1, and a mounting bracket 3 is provided between the impeller cover 2 and the fan 1. Four mounting positioning posts 4 are fixedly connected to the mounting bracket 3. Positioning bosses 5 are fixedly connected to the top of the impeller cover 2 and the top of the positioning posts 4. The bottom end of the positioning posts 4 is provided with a positioning groove 6 that matches the positioning bosses 5. By adding mounting brackets 3 between the impeller cover 2 and the fan 1, and the positioning grooves 6 at the bottom end of the positioning posts 4 that match the top of the positioning posts 4 and the positioning bosses 5 on the impeller cover 2, the mounting brackets 3 can be stacked and installed. Multiple mounting brackets 3 are added between the impeller cover 2 and the fan 1 according to the installation height difference between the impeller cover 2 and the fan 1, thereby reducing the height difference.

[0026] Please see Figure 1 - Figure 4 In this embodiment, the positioning boss 5 on the positioning post 4 has a first anchoring hole 7 that penetrates the positioning post 4, and the positioning boss 5 on the impeller cover 2 has a second anchoring hole 8 that matches the first anchoring hole 7. The bottom end of the fan 1 is fixedly connected to a support plate, and the support plate has a third anchoring hole 9 that is concentric with the first anchoring hole 7 and the second anchoring hole 8. Screws are screwed into the first anchoring hole 7, the second anchoring hole 8 and the third anchoring hole 9. The first anchoring hole 7 and the second anchoring hole 8 have the same diameter, which makes it convenient to fix them through an anchoring post and avoids displacement. The fan 1, the impeller cover 2 and a number of mounting brackets 3 sandwiched in the middle can be fixed together by the screws that serve as anchoring posts.

[0027] Please see Figure 5 - Figure 6 In this embodiment, a storage slot 10 is provided inside the vehicle. The fan 1, installed behind the impeller cover 2, is installed inside the storage slot 10. A square first insertion post 11, which is sleeved on the outside of the impeller cover 2, is inserted into the storage slot 10. An outer frame 12 located in front of the storage slot 10 is fixedly installed on the front side of the first insertion post 11. A socket 13 is provided inside the vehicle. A second insertion post 14, which matches the socket 13, is fixedly connected to the rear side of the outer frame 12. A slot 15 is provided on the socket 13. An elastic buckle 16, which matches the slot 15, is movably connected inside the second insertion post 14.

The outer frame 12 is made into an arc shape to avoid injury to the driver in the event of a collision. The second insertion post 14 is inserted into the insertion hole 13. Together with the first insertion post 11, it can make the installation of the outer frame 12 more tight and the insertion method is also easy to replace. When the elastic buckle 16 is inserted into the slot 15, it can fix the outer frame 12. When the elastic buckle 16 is squeezed and moved out of the slot 15, the outer frame 12 can be moved by pushing it outward. This design makes the disassembly of the outer frame 12 more convenient.

[0028] When working, the staff first selects the fan 1 to be used according to the installation space of the car and the requirements of the air conditioning performance. The fan 1 is placed on the impeller cover 2, and the height difference between it and the impeller cover 2 is measured. According to the height difference, the corresponding number of mounting brackets 3 are selected. The positioning groove 6 at the bottom of the mounting bracket 3 is aligned with the positioning boss 5 on the impeller cover 2. Then, another mounting bracket 3 is taken and the positioning groove 6 at the bottom is aligned with the positioning boss 5 at the top of the positioning post 4 of the previous mounting bracket 3. All mounting brackets 3 are installed in accordance with the above steps. Then, the screw is passed through the third anchoring hole 9 on the fan 1 and passed through the second anchoring hole 8 and the first anchoring hole 7 in an improved screwing manner to fix the fan 1 to the rear side of the impeller cover 2.

[0029] Place the impeller cover 2 in the storage groove 10, then insert the first insertion post 11 into the storage groove 10, align the second insertion post 14 with the second insertion hole 13, squeeze the elastic buckle 16 by hand, and insert the second insertion post 14 into the insertion hole 13. The inner wall of the insertion hole 13 squeezes the elastic buckle 16. When the second insertion post 14 moves in the insertion hole 13, when it moves to the position of the slot 15, the elastic buckle 16 pops out and snaps into the slot 15 to form a fixed position due to the loss of the squeezing of the inner wall of the insertion post.

[0030] When internal repairs are required, the elastic buckle 16 is squeezed to disengage it from the slot 15, and then the outer frame 12 is pulled outwards, so that the second insertion post 14 is removed from the insertion hole 13 and the first insertion post 11 is removed from the storage slot 10, and then the other internal components are inspected.

[0031] Through the above steps, a stackable mounting bracket 3 is installed between the impeller cover 2 and the fan 1. The bottom end of the positioning column 4 is provided with a positioning groove 6 that matches the top of the positioning column 4 and the positioning boss 5 on the impeller cover 2, so that the mounting bracket 3 can be continuously stacked. Depending on the installation height difference between the impeller cover 2 and the fan 1, different numbers of stacked mounting brackets 3 are installed between the impeller cover 2 and the fan 1 to reduce the height difference. The mounting bracket 3 has a simple structure, is highly practical, has low investment cost, high cost performance, and is easy to operate, thus solving the problem that the existing automotive air conditioning condenser fan 1 has different heights and there is an installation height difference between it and the impeller cover 2.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
