Description

Technical Field

[0001] This invention relates to the field of motor technology, and more specifically to a split-type vibration isolation and sealing structure for a brushless blower motor. Background Technology

[0002] In motors, vibration isolation and sealing structures isolate the vibration transmitted from the rotor rotation to the customer's installation interface, while also serving as a waterproof seal to prevent water from entering the PCB board.

[0003] In existing technologies, vibration isolation and sealing structures are integrally injection molded. The corresponding vibration isolation and sealing structures can be injection molded according to the specifications and shapes of the heat sinks of different motors.

[0004] However, existing vibration isolation and sealing structures, being integral in design, require a balance between vibration isolation and sealing performance. This necessitates the selection of materials with high buffering capacity, which in turn affects material costs and sealing performance, thus requiring improvement. Summary of the Invention

[0005] In view of this, the first objective of this application is to provide a split-type vibration isolation and sealing structure for a brushless blower motor, so as to significantly improve vibration isolation and waterproof performance while effectively controlling costs. The specific solution is as follows:

[0006] A split-type vibration isolation and sealing structure for a brushless blower motor includes a vibration isolation sealing body for mating and connecting with a heat dissipation aluminum plate. The vibration isolation sealing body includes a waterproof sealing ring and a buffer block. The buffer block is used to snap and fix the outer side of the waterproof sealing ring. The waterproof sealing ring is provided with a shaped plug-in ring and a mating connection groove. The buffer block is provided with a mating plug-in strip that matches and engages with the mating connection groove.

[0007] Preferably, the buffer block is U-shaped, the mating connector is located on the upper side of the lower end of the buffer block, and the opening of the buffer block faces the side of the heat dissipation aluminum plate and allows the heat dissipation aluminum plate to be inserted.

[0008] Preferably, the buffer block has abutment and vibration isolation protrusions on the outer side of the middle end and the upper side of the upper end.

[0009] Preferably, the mating grooves are intermittently distributed on the lower side of the waterproof sealing ring, and the waterproof sealing ring is provided with an abutting waterproof strip located between two adjacent mating grooves.

[0010] Preferably, the lower end of the buffer block is provided with a mating waterproof strip for connecting two adjacent abutting waterproof strips.

[0011] Preferably, the waterproof sealing ring is prepared by injection molding from TPE.

[0012] Preferably, the buffer block is made of silicone rubber.

[0013] The second objective of this application is to provide an application of a split vibration isolation and sealing structure for a brushless blower motor, including the use of the split vibration isolation and sealing structure for a brushless blower motor as described above, and its application to the blower motor.

[0014] Preferably, the blower motor includes a heat dissipation aluminum plate and a flange housing, the waterproof sealing ring is integrally injection molded with the heat dissipation aluminum plate, and the buffer block is used to fit onto the corner of the waterproof sealing ring and abut against the inner side of the flange housing for sealing and fixing.

[0015] Preferably, the bottom surface of the heat dissipation aluminum plate has a bottom groove on one side of its outer perimeter and a top groove located at the corner of its top surface; the bottom groove is matched and connected to the molded insertion ring; the top groove is for the upper lower side of the buffer block to be inserted and matched.

[0016] As can be seen from the above solutions, this application provides a split vibration isolation and sealing structure for a brushless blower motor. This split vibration isolation and sealing structure for the brushless blower motor has the following beneficial effects: By using a waterproof sealing ring and a buffer block to form the split vibration isolation and sealing structure of the brushless blower motor, it is convenient to use two materials with different functional properties to make the waterproof sealing ring and the buffer block respectively. Then, the waterproof sealing ring and the heat dissipation aluminum plate are integrally formed and fixed. Then, by installing the buffer block on the waterproof sealing ring, the dual functions of effective waterproofing and vibration isolation are achieved. While effectively reducing the manufacturing cost, the vibration isolation and waterproof performance of the split vibration isolation and sealing structure of the brushless blower motor are improved.

[0023] To make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 5 As shown, a split-type vibration isolation and sealing structure for a brushless blower motor includes a vibration isolation sealing body 1 for mating and connecting with a heat dissipation aluminum plate 2. In this embodiment, the vibration isolation sealing body 1 includes a waterproof sealing ring 11 and a buffer block 12, so that the waterproof sealing ring 11 achieves effective sealing and waterproofing while the buffer block 12 achieves shock absorption and pressure resistance.

[0025] The buffer block 12 is used to snap and fix the waterproof sealing ring 11 to the outside. The waterproof sealing ring 11 is provided with a shaped insertion ring 111 and a mating connection groove 112, and the buffer block 12 is provided with a mating insertion strip 121 that matches and engages with the mating connection groove 112. Therefore, the matching connection stability between the waterproof sealing ring 11 and the buffer block 12 will be significantly improved, and the vibration isolation and waterproof performance of the split vibration isolation sealing structure of the brushless blower motor will be improved.

[0026] like Figure 4 , Figure 5 As shown, the longitudinal section of the buffer block 12 is U-shaped. It should be mentioned that the connecting 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 allows the heat dissipation aluminum plate 2 to be inserted, thereby achieving the purpose of effective covering and fixing, and achieving effective buffering and vibration isolation after covering and fixing.

[0027] 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. Furthermore, to achieve an effective sealing and waterproofing effect, connecting grooves 112 are intermittently distributed on the lower side of the waterproof sealing ring 11, and abutment waterproof strips 113 are provided on the lower side of the waterproof sealing ring 11, located between two adjacent connecting grooves 112. To ensure an effective sealing and waterproofing effect when the buffer block 12 is connected to the waterproof sealing ring 11, a mating waterproof strip 122 for connecting two adjacent abutment waterproof strips 113 is provided on the lower side of the buffer block 12 in this embodiment. Therefore, the abutment waterproof strip 113 and the mating waterproof strip 122 achieve a waterproof sealing effect through sequential connection and mating.

[0028] The waterproof sealing ring 11 is made of TPE by injection molding. The buffer block 12 is made of silicone rubber. Therefore, through appropriate material adjustments, the vibration isolation seal 1 achieves high structural integrity and effective cost control.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, an application of a split-type vibration isolation and sealing structure for a brushless blower motor includes the use of the split-type vibration isolation and sealing structure for a brushless blower motor as described above, and its application to the blower motor. The blower motor includes a heat dissipation aluminum plate 2 and a flange housing 3. A waterproof sealing ring 11 is integrally injection molded with the heat dissipation aluminum plate 2. A buffer block 12 is used to fit around the corner of the waterproof sealing ring 11 and abuts against the inner side of the flange housing 3 for sealing and fixation. Simultaneously, a bottom groove 21 is provided on one side of the outer circumference 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 to a molded insertion ring 111, and the top groove 22 allows the upper end of the buffer block 12 to be inserted and matched. Therefore, when applying the split vibration isolation and sealing structure of the brushless blower motor, firstly, obtain the corresponding heat dissipation aluminum plate 2 according to the corresponding specifications and shape, then integrally injection mold a waterproof sealing ring 11 on the lower side of the heat dissipation aluminum plate 2, finally fix the processed buffer block 12 at the outer corner of the waterproof sealing ring 11, and then install and fix the completed heat dissipation aluminum plate 2 in the flange housing 3.

[0030] In summary, this application provides a split-type vibration isolation and sealing structure for a brushless blower motor. This split-type vibration isolation and sealing structure for the brushless blower motor is composed of a waterproof sealing ring 11 and a buffer block 12. This allows for the use of two materials with different functional properties to manufacture the waterproof sealing ring 11 and the buffer block 12 respectively. Furthermore, the waterproof sealing ring 11 is integrally formed and fixed to the heat dissipation aluminum plate 2. The buffer block 12 is then installed on the waterproof sealing ring 11 to achieve effective waterproofing and vibration isolation. This effectively reduces manufacturing costs while improving the vibration isolation and waterproofing performance of the split-type vibration isolation and sealing structure for the brushless blower motor.
