Description

Technical Field

[0001] The present invention relates to the technical field related to motors, and in particular to a motor end cover and an air suspension motor. Background Art

[0002] Most of the welding methods on motor products are resistance pressure welding, such as inductors and braided copper wires. In this state, there is a risk of falling off when welded under external force, affecting the reliability of the motor. At the same time, the braided copper wires piled together can easily cause the carbon brushes to get stuck, resulting in motor stalling. In addition, the current method of fixing the brush box in the motor has the problem of easy displacement during use, which in turn causes the carbon brushes to shift and cause the overall current of the motor to be too large. In response to the above problems, this application is proposed. Summary of the invention

[0003] The object of the present invention is to provide a motor end cover and an air suspension motor, which are used to overcome the problem of easy falling off in the resistance pressure welding method and the problem of easy accumulation of braided copper wire in traditional motor products.

[0004] The present invention is achieved through the following technical solutions.

[0005] A motor end cover of the present invention comprises an end cover body, an inductor, a braided copper wire, a buckle and a clamping welding structure. The inductor and the braided copper wire are arranged in two groups. The braided copper wire is used to connect with a carbon brush. The buckle and the clamping welding structure are both connected with the end cover body. The clamping welding structure comprises a clamping welding groove. The pins of the inductor and the braided copper wire are installed in the clamping welding groove to be clamped and welded. Compared with the traditional pressure welding method, it is not easy to fall off. The buckle is provided with a clamping groove. The clamping groove has a certain elastic deformation performance, and the width of the opening is smaller than the internal width. The braided copper wire is installed in the clamping groove, so that the routing path of the braided copper wire is consistent and stable, and accumulation is avoided.

[0006] Furthermore, a brush box is installed on the end cover body, carbon brushes are arranged inside the brush box, a mounting hole is arranged on the brush box, a positioning column is arranged on the end cover body, and the mounting hole is inserted into the positioning column to realize the positioning installation of the brush box.

[0007] Optionally, the positioning column and the brush box can be fixed by welding, hot melting, clamping, bolting, etc.

[0008] Furthermore, each brush box is provided with at least two groups of positioning columns, and the two groups of positioning columns are respectively provided on both sides of the brush box to achieve a stable and accurate positioning effect.

[0009] Furthermore, the two groups of positioning posts are distributed in sequence along the axial direction of the brush box, that is, they are staggered in the axial direction.

[0010] Furthermore, a convex ridge structure is provided on the end cover body, and the convex ridge structure encloses a brush box installation area. The brush box is installed at the brush box installation area, which plays the effect of further positioning the brush box and preventing it from shifting.

[0011] Furthermore, the clamping welding structure is arranged on the embedded component, and a clamping welding structure is arranged at each end of the embedded component, which is respectively used to connect with the pins of the inductor and the pins of the braided copper wire. The embedded component and the end cover body can be connected by screws or by clamping, etc. The embedded component extends on the back side of the end cover body, and the clamping welding structure passes through the through hole on the end cover body to the front side.

[0012] Furthermore, after the braided copper wire passes through the buckle and is connected to the clamping welding structure, the overall structure is U-shaped, which is convenient for the installation of the braided copper wire and makes the shape of the braided copper wire more stretched.

[0013] Furthermore, an inductive positioning structure is provided on the end cover body.

[0014] Furthermore, the opening of the clamping solder groove is arranged in a bell-mouth structure to facilitate the entry of the pin.

[0015] A motor is preferably used in an air suspension of a vehicle and is an air suspension motor, comprising the above-mentioned motor end cover.

[0016] The beneficial effects of the present invention are as follows: through the setting of the clamping welding structure, the pins of the inductor and the braided copper wire are installed in the clamping welding groove, clamped and welded. Compared with the traditional pressure welding method, it is not easy to fall off, thereby improving the reliability and service life of the motor; by setting the buckle, the braided copper wire is installed in the buckle, so that the routing path of the braided copper wire is consistent and stable. After the braided copper wire is stuck, it can avoid accumulation and prevent the motor from stalling due to the carbon brush being stuck; through the setting of the positioning column and the convex ridge structure, the brush box can be positioned and prevented from shifting, thereby avoiding the problem of the overall current of the motor being too large due to the carbon brush shift.

[0024] Combine the following Figure 1-Figure 5 The present invention is described in detail.

[0025] Embodiment 1:

[0026] A motor end cover of the present invention, such as Figure 1 , including an end cover body 1, an inductor 2, a brush box 3, a braided copper wire 4, a buckle 5 and a clamping welding structure 6. A carbon brush is arranged inside the brush box 3, and the braided copper wire 4 is used to connect with the carbon brush.

[0027] The inductor 2, brush box 3, carbon brush, braided copper wire 4, and buckle 5 are all arranged in two groups, which are symmetrically arranged. The buckle 5 can be made of polymer material or metal material. A card slot 51 is provided in the buckle 5. The card slot 51 has a certain elastic deformation performance, and the width of the opening is smaller than the internal width. The braided copper wire 4 is installed in the card slot 51, so that the routing path of the braided copper wire 4 is consistent and stable. After the braided copper wire 4 is stuck, it can avoid accumulation and prevent the motor from stalling due to the carbon brush being stuck. Preferably, after the braided copper wire 4 bypasses the buckle 5 and is connected to the clamping structure 6, the overall structure is U-shaped, which is convenient for the installation of the braided copper wire 4 and makes the shape of the braided copper wire 4 more stretched.

[0028] like Figure 2 An inductor positioning structure 11 is provided on the end cover body 1. The inductor positioning structure 11 adopts positioning plates provided on both sides of each inductor 2, and the inductor 2 is inserted between the positioning plates for installation.

[0029] like Figure 3 , 4 The clamping structure 6 is arranged on the embedded part 7, which is generally made of metal. A clamping structure 6 is arranged at each end of the embedded part 7, which is respectively used to connect with the pins of the inductor 2 and the pins of the braided copper wire 4. The embedded part 7 is connected to the end cover body 1 by screws. The embedded part 7 extends on the back side of the end cover body 1, and the clamping structure 6 passes through the through hole on the end cover body 1 to the front side.

[0030] Preferably, the opening of the solder clamping groove 61 is configured with a bell-mouth structure to facilitate entry of the pin.

[0031] The clamping welding structure 6 includes a clamping welding groove 61. The pins of the inductor 2 and the braided copper wire 4 are installed in the clamping welding groove 61, clamped and welded. Compared with the traditional pressure welding method, it is not easy to fall off, which improves the reliability and service life of the motor. The arrangement of the embedded part 7 will not affect the arrangement of other components in the end cover.

[0032] Embodiment 2:

[0033] On the basis of Example 1, in this embodiment, Figure 2 A positioning column 8 is provided on the end cover body 1, and the positioning column 8 is a cylinder. The brush box 3 is provided with a mounting hole 31, and the mounting hole 31 is inserted into the positioning column 8 to realize the positioning and installation of the brush box 3. Each brush box 3 is correspondingly provided with two groups of positioning columns 8, and the two groups of positioning columns 8 are respectively arranged on both sides of the brush box 3. The two groups of positioning columns 8 are distributed in sequence along the axial direction of the brush box 3, that is, they are staggered in the axial direction to achieve a stable and accurate positioning effect. A convex ridge structure 9 is provided on the end cover body 1, and the convex ridge structure 9 is a continuous or discontinuous type that encloses a brush box installation area. The brush box 3 is installed at the position of the brush box installation area, which plays a further role in positioning the brush box 3 and preventing it from shifting. Compared with the traditional motor in which the brush box is only connected by welding, hot melting, etc., the fixing method of the brush box in this scheme can prevent the brush box from shifting, and avoid the problem of the overall current of the motor being too large due to the carbon brush shift.
