Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a motor fixing device and an air conditioner. Background Technology

[0002] The internal motor of existing air conditioners is generally fixed using a motor bracket.

[0003] However, existing motor brackets generally use circular or "U"-shaped brackets to fix the motor. Circular brackets require the motor to be fixed within two circular clamps, while "U"-shaped brackets require the motor to be fixed via their "U"-shaped edges. Both types of motor brackets are prone to deformation under lateral impacts, necessitating the addition of crossbeams to improve structural stability, resulting in complex structures. Furthermore, existing motor brackets lack axial restraint between the clamps used to fix the motor and the bracket itself, causing the motor's rubber pads to easily detach, posing a safety hazard. Utility Model Content

[0004] This utility model provides a motor fixing device and an air conditioner to solve the defects of the existing motor bracket structure, which is complex and poses safety hazards.

[0005] This utility model provides a motor fixing device, including: The bracket has a connecting part and a mounting part. The connecting part is used to connect with the partition plate, and the mounting part has a first arc-shaped limiting edge and a second arc-shaped limiting edge, which are used to axially limit the rubber pads on both sides of the motor, respectively. Two arc-shaped limiting components are connected to the first arc-shaped limiting edge and the second arc-shaped limiting edge respectively to press the rubber pad.

[0006] According to the motor fixing device provided by this utility model, multiple bracket limiting claws are formed on both sides of the mounting part, and the bracket limiting claws are located outside the rubber pad, used to limit the outer end face of the rubber pad. The rubber pad is axially limited by the multiple bracket limiting claws located outside the rubber pad.

[0007] According to the motor fixing device provided by this utility model, the bracket limiting claw is a flanged structure formed by bending the bracket, and since the flanged structure forms a first ventilation hole on the bracket, the flanged structure satisfies the axial limiting function of the rubber pad on the one hand, and realizes the ventilation requirement on the other hand.

[0008] According to the motor fixing device provided by this utility model, the inner wall of each arc-shaped limiting member is formed with a third arc-shaped limiting edge, which is opposite to the first arc-shaped limiting edge or the second arc-shaped limiting edge. When the arc-shaped limiting member presses the rubber pad in place, an annular limiting edge structure is formed, thereby embedding into the groove of the outer wall of the rubber pad to achieve axial positioning.

[0009] According to the motor fixing device provided by this utility model, each of the arc-shaped limiting members has a positioning hole and a first mounting hole; the bracket also has a second mounting hole and a positioning plate, and the positioning plate is adapted to be inserted into the positioning hole, and the second mounting hole and the first mounting hole are adapted to be connected by fasteners.

[0010] According to the motor fixing device provided by this utility model, each of the arc-shaped limiting members has an arc-shaped flange, which is located on the outside of the rubber pad and is used to limit the outer end face of the rubber pad. It also provides axial limiting to the outer end face of the other side of the rubber pad, thereby ensuring uniform axial limiting of the outer end face of the rubber pad.

[0011] According to the motor fixing device provided by this utility model, the mounting part includes an integrally formed structure of a first plate, a second plate, a first crossbeam, and a second crossbeam. The first crossbeam is located at the top of the motor, and the second crossbeam is located at the bottom of the motor. Both the first and second crossbeams are connected between the first and second plates. Through the aforementioned double crossbeam structure, the load can be transferred to the other plate, and the first and second plates bear the load simultaneously, greatly increasing the axial impact resistance and load-bearing capacity.

[0012] According to the motor fixing device provided by this utility model, the first plate and / or the second plate form a second ventilation hole. Since the bracket occupies part of the air intake space, reducing wind resistance is beneficial to improving performance; multiple openings (including the first ventilation hole and the second ventilation hole) are provided on the side to reduce air intake resistance.

[0013] According to the motor fixing device provided by this utility model, the connecting part includes: The connecting edge has a third mounting hole and a connecting claw. The connecting claw is adapted to be inserted into a notch on the partition, and the third mounting hole is adapted to be connected to the partition by a fastener. This allows the bracket to be fixedly mounted on the partition.

[0014] This utility model also provides an air conditioner, including: the motor fixing device of this utility model.

[0015] This utility model provides a motor fixing device, comprising: a bracket and two arc-shaped limiting members. The bracket has a connecting part and a mounting part.

The structure is simple and the assembly is convenient. The bracket can be mounted on the partition through the connecting part, and the rubber pads are pressed by the arc-shaped limiting members, so that the rubber pads are axially positioned by the first arc-shaped limiting edge and the second arc-shaped limiting edge, preventing the rubber pads from falling outward.

[0016] Furthermore, the air conditioner provided by this utility model has the same advantages as described above because it includes the motor fixing device in the above embodiments of this utility model. Attached Figure Description

[0028] The following is combined with Figures 1 to 4 This invention describes a motor fixing device. The motor fixing device includes a bracket 100 and two arc-shaped limiting members 200.

[0029] The bracket 100 has a connecting part and a mounting part. The connecting part is used to connect with the partition 400. The mounting part has a first arc-shaped limiting edge 101 and a second arc-shaped limiting edge 102, which are used to axially limit the rubber pads on both sides of the motor 300, respectively. The arc-shaped limiting members 200 are connected to the first arc-shaped limiting edge 101 and the second arc-shaped limiting edge 102 in a corresponding manner to press the rubber pads.

[0030] Specifically, the motor fixing device of this utility model only includes two types of structural components, namely, a bracket 100 and two arc-shaped limiting components 200. Preferably, it only includes one bracket 100 and two arc-shaped limiting components 200 to fix the motor 300, which has the advantage of simple structure.

[0031] The bracket 100 is integrally formed by the connecting part and the mounting part. The connecting part is used to connect with the partition 400, thereby mounting the bracket 100 on the partition 400. The mounting part is used to cooperate with the arc-shaped limiting member 200 to fix the motor 300.

[0032] Arc-shaped limiting edges are formed on the left and right sides of the mounting section, namely the first arc-shaped limiting edge 101 and the second arc-shaped limiting edge 102. The arc-shaped limiting component 200 is installed correspondingly to the two arc-shaped limiting edges, thereby forming a ring-shaped limiting structure for axial positioning of the rubber pads on both sides of the motor 300. The rubber pads are installed on the outside of the output shaft of the motor 300. In this embodiment, a dual-shaft motor 300 is used, that is, the rubber pads support the left and right ends of the motor 300 respectively, and the motor 300 is supported by the rubber pads. Preferably, the left and right rubber pads are interference-fitted with the motor body, and the isolation of the rubber pads reduces the transmission of vibration.

[0033] The outer walls of the rubber pads on both sides of the motor 300 are formed with annular grooves, and the arc-shaped limiting edge can be inserted into the annular grooves to axially position them. In the following embodiments, the inner wall of the arc-shaped limiting member 200 is also formed with a similar arc-shaped limiting edge structure, thereby forming an annular protrusion structure that can cooperate with the above-mentioned annular grooves to achieve axial positioning of the rubber pads.

[0034] In addition, the two arc-shaped limiting members 200 have a radial pressing effect on the rubber pad, reducing the shaking generated by the motor 300 during operation, and cooperate with the first arc-shaped limiting edge 101 and the second arc-shaped limiting edge 102 to fix the motor 300.

[0035] This utility model provides a motor fixing device, comprising: a bracket 100 and two arc-shaped limiting members 200. The bracket 100 has a connecting part and a mounting part. The connecting part is used to connect with a partition 400, and the mounting part has a first arc-shaped limiting edge 101 and a second arc-shaped limiting edge 102, which are used to axially limit the rubber pads on both sides of the motor 300, respectively. The arc-shaped limiting members 200 are connected to the first arc-shaped limiting edge 101 and the second arc-shaped limiting edge 102 respectively to press the rubber pads. The motor fixing device provided by this utility model can fix the motor 300 with only three structural components: the bracket 100 and the two arc-shaped limiting members 200. The structure is simple and the assembly is convenient. The bracket 100 can be installed on the partition 400 through the connecting part. The rubber pads are pressed by the arc-shaped limiting members 200, so that the rubber pads are axially positioned by the first arc-shaped limiting edge 101 and the second arc-shaped limiting edge 102, preventing the rubber pads from falling outward.

[0036] In one embodiment of this utility model, multiple bracket limiting claws 103 are formed on both sides of the mounting portion, and the bracket limiting claws 103 are located outside the rubber pad to limit the outer end face of the rubber pad. Preferably, the bracket limiting claws 103 are located outside the arc-shaped limiting edge, that is, the bracket limiting claw 103 on the left side is located to the left of the left arc-shaped limiting edge, and the bracket limiting claw 103 on the right side is located to the right of the right arc-shaped limiting edge. The rubber pad is axially limited by the multiple bracket limiting claws 103 located outside the rubber pad. Specifically, multiple bracket limiting claws 103 on each side are arranged along the arc length direction of the first arc-shaped limiting edge 101 / second arc-shaped limiting edge 102 to ensure the limiting effect; preferably, two bracket limiting claws 103 are arranged along the arc length direction of the first arc-shaped limiting edge 101 / second arc-shaped limiting edge 102.

[0037] In one embodiment of this utility model, the bracket limiting claw 103 is a flanged structure formed by bending the bracket 100, and the flanged structure forms a first ventilation hole 104 on the bracket 100. Specifically, the arc-shaped limiting edge in the above embodiment adopts a flanged structure bent from the bracket 100, and a ventilation hole is formed in the original position, which satisfies the axial limiting function of the rubber pad on the one hand, and realizes the ventilation requirement on the other hand. The bracket limiting claw 103 in this embodiment does not damage the arc structure of the arc-shaped limiting edge, ensuring its positioning strength.

[0038] In one embodiment of this utility model, the inner wall of each arc-shaped limiting member 200 is formed with a third arc-shaped limiting edge 201. The third arc-shaped limiting edge 201 is opposite to the first arc-shaped limiting edge 101 or the second arc-shaped limiting edge 102. The rubber pad is axially limited by the first arc-shaped limiting edge 101 and the third arc-shaped limiting edge 201 or the second arc-shaped limiting edge 102 and the third arc-shaped limiting edge 201. In this embodiment, the inner wall of the arc-shaped limiting member 200 is formed with a third arc-shaped limiting edge 201 opposite to the first arc-shaped limiting edge 101 / second arc-shaped limiting edge 102. The first arc-shaped limiting edge 101, the second arc-shaped limiting edge 102 and the third arc-shaped limiting edge 201 are all semi-circular limiting edges. When the arc-shaped limiting member 200 presses the rubber pad into place, an annular limiting edge structure is formed, which is then embedded in the groove of the outer wall of the rubber pad to achieve axial positioning. It is understandable that the third arc-shaped limiting edge 201 is an arc-shaped protrusion structure on the inner wall of the arc-shaped limiting member 200, which is used to embed into the annular groove of the rubber pad.

[0039] In one embodiment of this utility model, each arc-shaped limiting member 200 has a positioning hole 202 and a first mounting hole 203; the bracket 100 also has a second mounting hole 105 and a positioning plate 106, and the positioning plate 106 is adapted to be inserted into the positioning hole 202, and the second mounting hole 105 and the first mounting hole 203 are adapted to be connected by fasteners. Specifically, the positioning plate 106 on the bracket 100 is adapted to be inserted into the positioning hole 202 of the arc-shaped limiting member 200 to achieve positioning of the arc-shaped limiting member 200 and the bracket 100, and the arc-shaped limiting member 200 is fixed on the bracket 100 by bolts and fasteners passing through the second mounting hole 105 and the first mounting hole 203 in sequence, and with the help of nuts. Preferably, the positioning hole 202 and the first mounting hole 203 are located at both ends of the arc-shaped limiting member 200.

[0040] Furthermore, the positioning hole 202, the third arc-shaped limiting edge 201, and the first mounting hole 203 on the arc-shaped limiting component 200 are arranged in the same vertical direction, unlike other screws which are placed eccentrically, thus maximizing the fixation and positioning of the rubber pad.

[0041] In one embodiment of this utility model, each arc-shaped limiting member 200 is formed with an arc-shaped flange 204, which is located on the outside of the rubber pad and is used to limit the outer end face of the rubber pad. In this embodiment, the arc-shaped flange 204 is opposite to the bracket limiting claw 103 mentioned above, and axially limits the outer end face of the other side of the rubber pad, thereby ensuring uniform axial limiting of the outer end face of the rubber pad. It can be understood that both the arc-shaped flange 204 and the bracket limiting claw 103 extend from the outside of the motor 300 toward the axis (i.e., the inside) of the motor 300.

[0042] In one embodiment of this utility model, the mounting part includes an integrally formed structure of a first plate 107, a second plate 108, a first crossbeam 109, and a second crossbeam 110. The first crossbeam 109 is located at the top of the motor 300, and the second crossbeam 110 is located at the bottom of the motor 300. Both the first crossbeam 109 and the second crossbeam 110 are connected between the first plate 107 and the second plate 108. In this embodiment, the first plate 107 and the second plate 108 are connected by the first crossbeam 109 and the second crossbeam 110, and are integrally formed. When the motor 300 generates an axial impact on the first plate 107 or the second plate 108, the impact can be transferred to the other plate through the aforementioned double crossbeam structure. The first plate 107 and the second plate 108 are simultaneously subjected to force, greatly increasing the axial impact resistance and load-bearing capacity.

[0043] In one embodiment of this utility model, the first plate 107 and / or the second plate 108 are provided with second ventilation holes 111. Preferably, both the first plate 107 and the second plate 108 are provided with multiple second ventilation holes 111. Since the bracket 100 occupies part of the air intake space, reducing wind resistance is beneficial to improving performance; multiple openings (including the first ventilation hole 104 and the second ventilation hole 111) are provided on the side to reduce air intake resistance, and the openings are flanged, which also serves as reinforcing ribs, increasing the overall strength of the bracket 100.

[0044] In one embodiment of this utility model, the connecting part includes a connecting edge 112, on which a third mounting hole 113 and a connecting claw 114 are formed. The connecting claw 114 is adapted to be inserted into a notch on the partition 400, and the third mounting hole 113 is adapted to be connected to the partition 400 by a fastener. Specifically, the bracket 100 is positioned by inserting the connecting claw 114 into the notch on the partition 400. Then, the bracket 100 is fixedly installed on the partition 400 by bolts and fasteners passing through the third mounting hole 113 and the mounting hole on the partition 400, and cooperating with nuts.

[0045] This utility model also provides an air conditioner. The air conditioner includes the motor fixing device described in the above embodiments of this utility model. Specifically, the motor fixing device described in the above embodiments is applied to a ducted air conditioner.

[0046] The air conditioner provided by this utility model has the same advantages as described above because it includes the motor fixing device in the above embodiments of this utility model.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
