[0018] To make the technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] like Figure 5 As shown, a split-type vibration isolation seal structure for a brushless blower motor includes a vibration isolation seal body 1 for mating with a heat dissipation aluminum plate 2. In the embodiment of the present application, the vibration isolation seal body 1 includes a waterproof seal ring 11 and a buffer block 12. The waterproof seal ring 11 achieves effective sealing and waterproofing, while the buffer block 12 achieves shock absorption and pressure resistance.

[0020] The buffer block 12 is designed to be snap-fastened to the outside of the waterproof seal ring 11. The waterproof seal ring 11 is provided with a molded insert ring 111 and a mating connection groove 112, and the buffer block 12 is provided with a mating insert strip 121 that mates with the mating connection groove 112. This significantly improves the mating connection stability between the waterproof seal ring 11 and the buffer block 12, and enhances the vibration isolation and waterproofing performance of the brushless blower motor's split vibration isolation seal structure.

[0021] like Figure 4 、 Figure 5 As shown, the longitudinal section of the buffer block 12 is U-shaped. It should be mentioned that the mating connector strip 121 is located on the upper side of the lower end of the buffer block 12, and the opening of the buffer block 12 faces the side of the heat dissipation aluminum plate 2 and is inserted into the heat dissipation aluminum plate 2, thereby achieving the purpose of effective covering and fixing, and achieving effective buffering and vibration isolation after covering and fixing.

[0022] In order to effectively improve the buffering and vibration isolation performance of the buffer block 12, abutment vibration isolation protrusions 123 are provided on the outer side of the middle end and the upper side of the upper end of the buffer block 12. And in order to achieve an effective sealing and waterproof effect, the matching connection grooves 112 are intermittently distributed on the lower side of the waterproof sealing ring 11, and abutment waterproof strips 113 located between two adjacent matching connection grooves 112 are provided on the lower side of the waterproof sealing ring 11. In order to achieve an effective sealing and waterproof effect when the buffer block 12 is matched with the waterproof sealing ring 11, a matching waterproof strip 122 for connecting two adjacent abutment waterproof strips 113 is provided on the lower side of the lower end of the buffer block 12 in the embodiment of the present application. Therefore, the abutment waterproof strip 113 and the matching waterproof strip 122 will achieve a waterproof sealing effect by being connected and matched in sequence.

[0023] The waterproof seal ring 11 is made of TPE by injection molding, and the buffer block 12 is made of silicone rubber. Therefore, by adjusting the corresponding materials, the vibration isolation seal body 1 has high structural integrity and effectively controls costs.

[0024] like Figure 1 、 Figure 2 、 Figure 3 As shown, an application of a split-type vibration isolation sealing structure for a brushless blower motor includes adopting the split-type vibration isolation sealing structure for a brushless blower motor as described above, and applying it to the blower motor. The blower motor includes a heat dissipation aluminum plate 2 and a flange shell 3, a waterproof sealing ring 11 and the heat dissipation aluminum plate 2 are integrally formed by injection molding, and a buffer block 12 is used to be sleeved on the corners of the waterproof sealing ring 11, and is sealed and fixed with the inner side of the flange shell 3. At the same time, a bottom groove 21 is provided on one side of the outer periphery of the bottom surface of the heat dissipation aluminum plate 2, and a top groove 22 is provided on the top surface at the corner. The bottom groove 21 is matched and connected with the molded plug ring 111, and the top groove 22 is provided for the upper end lower side of the buffer block 12 to be inserted and matched. Therefore, when applying the split vibration isolation sealing structure of the brushless blower motor, first obtain the corresponding heat dissipation aluminum plate 2 according to the corresponding specifications and shapes, then integrally injection-mold a waterproof sealing ring 11 on the lower side of the heat dissipation aluminum plate 2, and finally fix the processed buffer block 12 at the outer corners of the waterproof sealing ring 11, and install and fix the installed heat dissipation aluminum plate 2 in the flange shell 3.

[0025] In summary, the present application provides a split vibration isolation sealing structure for a brushless blower motor. The split vibration isolation sealing structure of the brushless blower motor adopts a waterproof sealing ring 11 and a buffer block 12 to form the split vibration isolation sealing structure of the brushless blower motor, so that it is convenient to use two materials with different functional properties to make the waterproof sealing ring 11 and the buffer block 12 respectively, and then the waterproof sealing ring 11 and the heat dissipation aluminum plate 2 are integrally formed and connected and fixed, and then the buffer block 12 is installed on the waterproof sealing ring 11 to achieve the dual effects of effective waterproofing and vibration isolation. While effectively reducing the production cost, the vibration isolation and waterproof performance of the split vibration isolation sealing structure of the brushless blower motor are improved.
