Description

Technical Field

[0001] The utility model relates to the technical field of motor accessories, in particular to a motor bracket. Background Art

[0002] Through searching, the prior art with announcement number CN220307022U was found. Its general scheme is as follows: it includes a bracket main body, a boss is provided in the middle position of the bracket main body, and an axial hole for rotating installation of the power supply motor shaft is opened in the center of the boss. The bracket main body extends outward and has two shoulders, and a carbon brush groove is provided in the shoulder. A carbon brush is installed in the carbon brush groove, and a mounting column is provided at the outer opening of the carbon brush groove. A torsion spring is installed on the mounting column, one end of the torsion spring is connected to the outer end of the carbon brush installed in the carbon brush groove, and the other end is fixedly connected to the bracket main body. The purpose of the utility model is to solve the problems of cumbersome installation, complex structure and high cost of the existing motor bracket by arranging a mounting column and sleeved with a torsion spring on the mounting column.

[0003] Although it solves the problem of inconvenient carbon brush installation, after it is installed on the rotor, the lead wires of the stator still need to be covered with a sleeve and the conduit must be fixed with a cable tie, which makes it difficult to improve the production efficiency of the motor. Utility Model Content

[0004] The purpose of the present invention is to provide a motor bracket to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a motor bracket, comprising a rotor seat for supporting one end of a rotor and a carbon brush mounting seat arranged on the rotor seat; a first support frame is provided at one end of the rotor seat, and a second support frame is provided on the other side of the rotor seat; mounting holes are provided on both the first support frame and the second support frame, and the terminal is pierced through the mounting hole to pierce the outer skin of the enameled wire in the mounting hole and directly contact the copper wire.

[0006] As a preferred technical solution of the present invention: the first support frame and the second support frame are both connected to the rotor seat via a connecting rod.

[0007] As an optimal technical solution of the present invention: heat dissipation holes are provided on both sides of the rotor seat.

[0008] As a preferred technical solution of the present invention: both the first support frame and the second support frame are provided with an axle pin seat.

[0009] As a preferred technical solution of the present invention: both the first support frame and the second support frame are provided with through holes.

[0010] By adopting the above technical solution, the beneficial effect of the utility model is as follows: the normal operation of the motor can be achieved by connecting the puncture terminal to the mounting hole and then connecting the external power cord to the puncture terminal, so that the stator of the motor does not need a lead wire; the process of threading the lead wire through the sleeve and tightening the lead wire is omitted, thereby improving the production efficiency of the motor while reducing labor input and thus reducing the production cost of the motor.

[0014] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0015] See also Figure 1-2 The utility model provides an embodiment: a motor bracket, including a rotor seat 5 for supporting one end of the rotor and a carbon brush mounting seat 6 arranged on the rotor seat 5; a first support frame 1 is provided at one end of the rotor seat 5, and a second support frame 2 is provided on the other side of the rotor seat 5; the first support frame 1 and the second support frame 2 are both provided with mounting holes 3, and the terminal is pierced through the mounting hole 3 to pierce the outer skin of the enameled wire in the mounting hole 3 and directly contact the copper wire.

[0016] In summary, when the piercing terminal contacts the enameled wires on the two support frames, and then the external power line is connected to the piercing terminal, the motor can operate normally, thereby eliminating the need for lead wires from the motor stator. This eliminates the need for the lead wires to be threaded through a casing and tied together, thereby improving motor production efficiency while reducing labor input and thus lowering motor production costs. Among them, the piercing terminal is purchased on the market, and it can be used to pierce the paint film of the enameled wire and then contact the bare wire inside the enameled wire, that is, the copper wire, to achieve the ability to conduct electricity.

[0017] Furthermore, since the first support frame 1 and the second support frame 2 are both connected to the rotor base 5 via the provided connecting rod 4, the connecting rod 4 is used to extend the gap between the rotor base 5 and the two support frames, thereby improving the heat dissipation capacity of the device.

[0018] Furthermore, since heat dissipation holes 9 are provided on both sides of the rotor seat 5, the heat dissipation effect of the device can be further improved.

[0019] Furthermore, since both the first support frame 1 and the second support frame 2 are provided with a pin holder 8, once the carbon brush is mounted on the carbon brush mount 6, the torsion spring fits over the pin holder 8, ensuring smooth contact between the carbon brush and the rotor. Specifically, the mount 6 is designed to be located in the center of the stator coil, shortening the connection length between the enameled wire and the carbon brush wire. This solves the problem of excessively long stator enameled wire-carbon brush connection spans, leading to enameled wire breakage, enameled wire and connection terminals contacting the stator chips, and resulting in motor leakage.

[0020] In addition, since both the first support frame 1 and the second support frame 2 are provided with through holes 7 , it is convenient to fix the two support frames on the motor after the bolts pass through the through holes 7 .

[0021] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
