[0001] This utility model relates to the field of blower motor sealing installation technology, and in particular to a blower motor sealing structure. Background Technology

[0002] As a key component in industrial and automotive fields, the sealing performance of the motor cooling system of a blower directly affects the reliability and service life of the equipment. In traditional blower designs, the motor cooling system typically employs forced air cooling or liquid cooling, where the sealing structure plays a crucial role in preventing cooling medium leakage and isolating external contaminants.

[0003] Existing technologies generally employ a split-type sealing solution, which involves placing a separate rubber sealing ring or metal seal at the junction of the motor housing and the cooling system, achieving static sealing through compression. This sealing method requires independent machining of the sealing groove, pre-installation and positioning of the seal, and a multi-step assembly process. The process is cumbersome, prone to seal failure due to improper assembly, and involves a large number of parts, increasing management and production costs. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the blower motor sealing structure provided in this embodiment includes: a flange 100, a motor assembly 200, and a sealing member 300; the flange 100 is provided with a mounting hole 110 for mounting the motor assembly 200, specifically, the mounting hole 110 is formed through the middle of the flange 100.

[0024] The sealing component 300 is formed on the inner wall of the mounting hole 110. The sealing component 300 seals the motor assembly 200 and the mounting hole 110. Specifically, the sealing component 300 is made of rubber and is integrally molded with the flange 100, for example, through injection molding, casting, or 3D printing. This ensures good structural stability and sealing performance between the sealing component 300 and the flange 100. During assembly, the operator only needs to insert the motor assembly 200 into the designed position along the direction of the mounting hole 110. Since the sealing component 300 is already formed on the inner wall of the mounting hole 110, it naturally conforms to the outer surface of the motor assembly 200, achieving a good sealing effect. No additional sealing ring is required, simplifying the assembly process and improving assembly efficiency.

[0025] Furthermore, such as Figure 5 and Figure 6 As shown, the flange 100 has a cooling channel 120 inside. When the motor assembly 200 is assembled in the mounting hole 110, the cooling channel 120 is connected to the motor assembly 200 and is used to deliver cooling gas to the motor assembly 200, thereby realizing the heat dissipation function of the motor assembly 200 and improving the stability and life of the motor operation.

[0026] In a preferred embodiment, the flange 100 is provided with an air inlet 130, which is connected to the cooling channel 120 for connecting to an external cooling gas source, such as a fan or compressed air system, to introduce cooling gas into the cooling channel 120.

[0027] like Figure 4 As shown, the motor assembly 200 includes a motor housing 210. An air inlet 211 is provided on the side wall of the motor housing 210. The air inlet 211 is connected to the cooling channel 120, so that the cooling gas can smoothly enter the interior of the motor housing 210 to cool the internal components of the motor.

[0028] It should be noted that after the motor assembly 200 is assembled, the sealing component 300 is positioned higher than the air inlet 211 to ensure that the gas in the cooling channel 120 can smoothly enter the air inlet 211.

[0029] In an optional embodiment, the blower motor sealing structure further includes a flow guide end cover 400; the flange 100 is provided with an end cover hole, the flow guide end cover 400 is placed on the end cover hole, and a cooling channel 120 is formed between the flow guide end cover 400 and the inner wall of the flange 100, so that the cooling channel 120 can be formed after the flow guide end cover 400 is installed in place.

[0030] To ensure the sealing between the guide end cover 400 and the flange 100, the blower motor sealing structure also includes a guide seal 500, which is disposed at the end of the end cover hole wall and is used to seal the gap between the guide end cover 400 and the end cover hole.

[0031] The flow guide end cap 400 has a slot. When the flow guide end cap 400 is installed, the wall of the end cap hole extends into the slot, so that the flow guide seal 500 is located in the slot, thereby achieving a seal between the flow guide end cap 400 and the end cap hole of the flange 100.

[0032] In an optional embodiment, the blower motor sealing structure further includes a sealing connector 600; one end of the sealing connector 600 is connected to the sealing member 300, and the other end of the sealing connector 600 is connected to the flow guiding seal 500. The sealing connector 600 is disposed on the surface of the flange 100. It should be noted that the sealing connector 600, the sealing member 300 and the flow guiding seal 500 are an integral structure and are all made of rubber.

[0033] In an optional embodiment, the motor assembly 200 further includes a motor end cover 220, which covers the opening of the motor housing 210 and is detachably connected to the motor housing 210 by bolts, snaps or other means, so as to facilitate the installation, maintenance and replacement of the motor assembly 200.

[0034] The blower motor sealing structure provided in this embodiment has the following technical advantages: 1. Significantly Improved Assembly Efficiency: By integrating the sealing component 300 with the flange 100 into a single unit, during the assembly of the motor assembly 200, the motor assembly 200 only needs to be inserted into the mounting hole 110 of the flange 100 according to the designed position. Utilizing the clearance fit between the motor assembly 200 and the mounting hole 110, the sealing component 300 automatically conforms to the outer surface of the motor housing, thus achieving the sealing function. This design eliminates the step of separately installing the sealing ring in the traditional assembly process, simplifying the assembly process and improving overall assembly efficiency.

[0035] 2. Fewer parts and simpler structure: Since the sealing component 300 is integrated into the flange 100, there is no need to configure separate sealing rings or other sealing elements. This reduces the types and number of parts, lowers the cost of parts management and inventory, and makes the overall structure more compact and simple, which is conducive to the miniaturization and lightweight design of the equipment.

[0036] 3. Enhanced Sealing Reliability: Traditional sealing methods rely on manual assembly of the sealing ring, which carries risks such as improper assembly, misalignment, and uneven compression, easily leading to seal failure. This embodiment utilizes an integrated, molded sealing structure, allowing the sealing component 300 to naturally fit against the motor housing. This avoids human assembly errors, improves the stability and reliability of the seal, thereby extending the equipment's service life and reducing maintenance frequency.

[0037] 4. Reduce assembly difficulty and improve process adaptability: This structure does not require complex assembly processes and special tools, is easy to operate, has low technical requirements for operators, is suitable for mass production and automated assembly processes, and has good engineering application prospects.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
