[0043] The lead wires are prone to wear and tear, which can cause safety accidents. The reason for this problem is that in the relevant technology, the lead wires in the stator are connected to the external power supply after passing through the opening of the motor end cover. When the lead wires pass through the motor end cover, the lead wires are only led out from the opening of the motor end cover. When the motor is working, the motor will vibrate, and the vibration will drive the lead wires to shake, causing the lead wires to wear and tear, exposing the wire part of the lead wire used to transmit current. In addition, the lead wires are easily pulled out from the inside of the motor, or the lead wires outside the motor are easily pushed into the motor, causing motor failure and easily causing safety accidents.

[0044] In view of the above technical problems, the embodiment of the utility model provides a motor end cover and a motor, by setting at least one opening on the outer peripheral surface of the end cover body, the opening is connected to the inside of the end cover body, and the at least one opening is used to lead out the lead wire of the power supply, so that the lead wire can pass through the opening to connect with the external power supply, and by setting a pressure plate at the opening, and the pressure plate presses the lead wire to the inner wall of the opening, so that the lead wire is constrained and fixed by the pressure plate, and the lead wire is prevented from shaking due to the vibration of the motor when the motor is working, thereby avoiding the lead wire from rubbing against the side wall or side of the opening, and preventing the lead wire from being worn and broken due to shaking to cause a safety accident. In addition, due to the pressing effect of the pressure plate on the lead wire, it is not easy to pull the lead wire out from the inside of the motor, and the lead wire is not easy to push into the motor from the outside of the motor, thereby avoiding the pulling out and pushing in of the lead wire. In addition, the lead wire is crimped at the opening through a pressure plate, and the pressure plate is located in the opening of the end cover body, that is, the opening is used as a storage space for the pressure plate, so that the pressure plate does not occupy additional remaining space on the motor. Compared with the existing lead wire terminal, since the pressure plate does not occupy additional space, the volume of the motor end cover is reduced, the volume of the motor is reduced, and the motor tends to be miniaturized.

[0045] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0046] refer to Figure 1 The embodiment of the utility model provides a motor end cover, which is a component with lead wires at the end of the motor. The motor end cover is used to close one end of the motor, and the lead wires of the motor are led out from the motor end cover. The motor end cover includes an end cover body 100 and a pressure plate 200. The end cover body 100 is the main structure of the motor end cover. Figure 2 As shown, the shape of the end cover body 100 is approximately cylindrical, and the outer peripheral surface of the end cover body 100 is provided with at least one opening 110, and the number of the openings 110 can be one, two, three or more. In this embodiment, the number of the openings 110 is four. The opening 110 is connected to the interior of the end cover body 100, such as Figure 2 As shown, the opening 110 is connected to the internal cavity of the end cover body 100, at least one opening 110 is used to lead out the lead wire 300 of the electric machine, and the remaining openings can be used as ventilation holes, etc.

[0047] For ease of description, the opening 110 from which the lead wire 300 of the motor is led out is defined as the first opening 111 below. It should be noted that the number of the first openings 111 is not limited, for example, it can be one, two or more. When the number of the first openings 111 is one, all the lead wires 300 can be led out from one first opening 111. When the number of the first openings 111 is two, a part of the lead wire 300 can be led out from one of the first openings 111, and another part of the lead wire 300 can be led out from another first opening 111. The remaining openings 110 (for example, as ventilation openings) except the first opening 111 are defined as the second opening 112. After the lead wire 300 passes through the first opening 111, it can be connected to an external power supply, so that the lead wire 300 can be led out from the inside of the motor end cover.

[0048] A pressing plate 200 is provided at each opening 110, and the pressing plate 200 can fix the lead wire 300. The shape of the pressing plate 200 matches the shape of the opening 110. For example, if the shape of the opening 110 is circular, the shape of the pressing plate 200 is circular, and the diameters of the pressing plate 200 and the opening 110 are the same; or if the shape of the opening 110 is rectangular, the shape of the pressing plate 200 is rectangular, and the length and width of the pressing plate 200 are the same as the length and width of the opening 110.

[0049] At least one pressing plate 200 presses the lead wire 300 against the inner wall of the corresponding opening 110. For ease of description, the pressing plate 200 that presses the lead wire 300 is defined as a first pressing plate 210, and the remaining pressing plates 200 except the first pressing plate 210 are defined as second pressing plates 220. Figure 1 As shown, a first pressing plate 210 is provided at the first opening 111, and the first pressing plate 210 presses the lead wire 300 against the inner wall of the first opening 111. A second pressing plate 220 is provided at the second opening 112, and the second pressing plate 220 presses against the inner wall of the second opening 112. The lead wire 300 is pressed against the inner wall of the first opening 111 by the first pressing plate 210, so that the lead wire 300 is constrained and fixed by the first pressing plate 210, and the lead wire 300 is prevented from shaking, and the lead wire 300 is prevented from shaking due to the vibration of the motor when the motor is working.

[0050] The utility model embodiment provides a motor end cover, by setting at least one opening 110 on the outer peripheral surface of the end cover body 100, the opening 110 is connected to the interior of the end cover body 100, and the first opening 111 in the opening 110 is used to lead out the lead wire 300 of the power supply, so that the lead wire 300 can pass through the first opening 111 and connect with the external power supply, by setting a first pressing plate 210 at the first opening 111, and the first pressing plate 210 presses the lead wire 300 to the inner wall of the first opening 111, so that the lead wire 300 is constrained and fixed by the first pressing plate 210, so that the lead wire 300 is prevented from shaking due to the vibration of the motor when the motor is working, thereby avoiding the lead wire 300 from rubbing against the side wall or side of the first opening 111, and preventing the safety accidents caused by the wear and tear of the lead wire 300. In addition, the pressing effect of the pressure plate 200 on the lead wires makes it impossible for the lead wires to be pulled out from the inside of the motor, or pushed into the motor from the outside of the motor. That is, the pressure plate prevents the lead wires from being pulled out and pushed in, thereby avoiding the motor lead wires being pulled out of the motor or pushed into the motor, causing the motor to short-circuit, open circuit or get stuck.

[0051] refer to Figure 2 In some embodiments, the bottom wall of the first opening 111 is provided with an elongated protrusion 120, which extends from the bottom wall of the first opening 111 away from the bottom wall, is located in the middle of the bottom wall, and has a first side surface 121 and a second side surface 122 that are oppositely disposed. Figure 2 As shown, the first side surface 121 is the left side surface of the long strip protrusion 120 , and the second side surface 122 is the right side surface of the long strip protrusion 120 .

[0052] Continue to refer Figure 2 The side wall of the first opening 111 is provided with an annular step structure 130, the step structure 130 extends from the inner side wall of the first opening 111 toward the inside of the first opening 111, and the step structure 130 has a third side surface 131 and a fourth side surface 132 which are arranged opposite to each other. Figure 2 As shown, the third side surface is the left side surface of the step structure 130 , and the fourth side surface 132 is the right side surface of the step structure 130 .

[0053] Continue to refer Figure 2 The top of the long strip protrusion 120 is flush with the top of the step structure 130, and the first pressure plate 210 is crimped to the top of the long strip protrusion 120 and the top of the step structure 130. For example, the middle part of the first pressure plate 210 is crimped to the top of the long strip protrusion 120, and the part of the first pressure plate 210 close to the edge is crimped to the top of the step structure 130, so that the first pressure plate 210 can be stably installed in the first opening 111.

[0054] Continue to refer Figure 2The bottom wall of the first opening 111, the first side surface 121, the top of the first pressing plate 210 and the third side surface 131 surround and form a first channel 140, and the first channel 140 can be used to lead out the lead wire 300. The bottom wall of the first opening 111, the second side surface 122, the top of the first pressing plate 210 and the fourth side surface 132 surround and form a second channel 150, and the second channel 150 can be used to lead out the lead wire 300.

[0055] The lead wire 300 can be led out from any one of the first channel 140 and the second channel 150, or the lead wire 300 can be led out from both the first channel 140 and the second channel 150 at the same time. Figure 1 As shown, there are four lead wires 300, two of which are led out from the first channel 140, and the other two are led out from the second channel 150. In this embodiment, the first channel 140 and the second channel 150 provide lead-out space for the lead wires 300. Compared with directly crimping the lead wires 300 to the bottom wall of the first opening 111 through the first pressing plate 210, the motor end cover in this embodiment can reduce or avoid damage to the lead wires 300 caused by the first pressing plate 210 crimping the lead wires 300.

[0056] refer to Figure 1 and Figure 2 In some embodiments, there are four openings 110, four pressing plates 200, and the four pressing plates 200 are respectively located at the four openings 110. Specifically, there is one first opening 111 and one first pressing plate 210, and three second openings 112 and two second pressing plates 220. Each second pressing plate 220 is pressed against the bottom wall of the second opening 112. The connection between the second pressing plate 220 and the second opening can be threaded, clamped, or riveted. This arrangement makes it easy to install the second pressing plate 220.

[0057] refer to Figure 1 In some embodiments, the four openings 110 are arranged at equal intervals along the outer circumference of the end cover body 100. The four openings 110 may also be arranged at intervals along the outer circumference of the end cover body 100, and the intervals between adjacent openings 110 are different.

[0058] refer to Figure 1 and Figure 3 In some embodiments, the pressing plate 200 has a window 230, the window 230 is connected to the corresponding opening 110, and the window 230 runs through the pressing plate 200. For example, the first pressing plate 210 and the second pressing plate 220 both have a window 230, the window 230 in the first pressing plate 210 is connected to the first opening 111, and the window 230 in the second pressing plate 220 is connected to the corresponding second opening 112. The window 230 enables the motor end cover to be connected inside and outside, which is convenient for ventilation, thereby improving the heat dissipation performance of the motor end cover.

[0059] In some embodiments, the motor end cover further includes a cover plate for closing the window 230, and each window 230 is provided with a cover plate, which is detachably mounted on the corresponding window 230, for example, the cover plate is mounted on the corresponding window 230 by means of threaded connection, clamping, etc. When the motor end cover or the motor needs ventilation and heat dissipation, the cover plate is opened, and ventilation and heat dissipation are performed through each window 230. When the motor end cover or the motor is not in a working state and ventilation and heat dissipation are not required, the cover plate can be closed, and the corresponding window 230 is closed by the cover plate to prevent foreign matter from entering the inner wall of the motor end cover through the window 230.

[0060] refer to Figure 1 In other embodiments, the pressure plate 200 is provided with a mesh structure 240 at the window 230, and the mesh structure 240 can be pressed on the side of the pressure plate 200 close to the bottom wall of the opening 110. The mesh structure 240 is a structure provided with tiny holes. In this way, the window 230 can prevent debris from entering the motor end cover while maintaining ventilation, thereby improving safety.

[0061] In some embodiments, the mesh structure 240 is an electromagnetic shielding net, which is a device or component that can reduce electromagnetic interference. The electromagnetic shielding net can be copper, aluminum or nickel-plated conductive cloth, etc., and a shielding body is made of metal and other electromagnetic shielding materials to enclose the area to be protected and isolate the electromagnetic noise outside the shielding body. Such a setting can improve the electromagnetic shielding performance of the motor end cover. Therefore, by setting the mesh structure as an electromagnetic shielding net, when the electromagnetic shielding net is set at the window, the three functions of ventilation, foreign body prevention and electromagnetic shielding can be achieved.

[0062] refer to Figure 1 In some embodiments, as Figure 3 As shown, the pressing plate 200 is provided with a through hole 250, that is, the first pressing plate 210 and the second pressing plate 220 are both provided with a through hole 250. Figure 2 As shown, the elongated protrusion 120 of the first opening 111 is provided with a threaded hole 123, and a screw is inserted between the through hole 250 in the first pressing plate 210 and the threaded hole 123 in the elongated protrusion, and the first pressing plate 210 is fixed to the end cover body 100 by the screw, so that the first pressing plate 210 is installed in the first opening 111. The bottom wall of the second opening 112 can be provided with a threaded hole 123, and a screw is inserted between the through hole 250 in the second pressing plate 220 and the threaded hole 123 in the bottom wall of the second opening 112, and the second pressing plate 220 is fixed to the end cover body 100 by the screw, so that the second pressing plate 220 is installed in the second opening 112. In this embodiment, the pressing plate 200 and the opening 110 are installed by screws, which is simple to operate and low in cost.

[0063] The present application also provides a motor, which includes a stator 400, a rotor 500 and any one of the motor end covers described above. The specific structure of the motor end cover is shown in the above embodiment. Figure 1 As shown, the motor end cover is connected to one side of the stator 400, the motor end cover and the stator 400 are sleeved on the rotor 500, one end of the rotor 500 can be rotatably connected to the motor flange 600, and the other end of the rotor 500 passes through the motor end cover, and the stator 400 and the rotor are installed in coordination to realize the motor function, and the motor end cover includes the lead wire 300 of the motor, for example, the first end of the lead wire 300 is connected to the brush assembly of the stator 400, and the second end of the lead wire 300 is led out from an opening 110 of the motor end cover, specifically, the second end of the lead wire 300 is led out from the first opening 111 of the motor end cover. Since the motor adopts all the technical solutions of any of the above embodiments, it has at least all the beneficial effects brought by any of the above embodiments, which will not be repeated here.

[0064] In the embodiment of the present application, the stator 400 may include a housing and a magnetic steel, and the magnetic steel may be arranged in the housing. The motor end cover may be connected to the housing of the stator 400.

[0065] The motor provided by the present application uses a pressure plate 200 to press the lead wire 300 onto the inner wall of the opening, so that the lead wire is constrained and fixed by the pressure plate, preventing the lead wire 300 from shaking due to the vibration of the motor when the motor is working, thereby preventing the lead wire 300 from rubbing against the side wall or side edge of the opening, and preventing the lead wire 300 from being worn and broken due to shaking to cause a safety accident. In addition, due to the pressing effect of the pressure plate 200 on the lead wire 300, the lead wire 300 cannot be pulled out from the inside of the motor, and the lead wire 300 cannot be pushed into the motor from the outside of the motor. Therefore, the pressure plate prevents the lead wire from being pulled out and pushed in, avoiding the pull-out and push-in of the lead wire 300, which causes the motor to short-circuit, open circuit or jam. In addition, the lead wire 300 is crimped at the opening through the pressure plate 200, and the pressure plate 200 is located in the opening of the end cover body, that is, the opening is used as a storage space for the pressure plate, so that the pressure plate 200 does not occupy additional remaining space on the motor. Compared with the existing lead wire terminal, since the pressure plate does not occupy additional space, the volume of the motor end cover is reduced, the volume of the motor is reduced, and the motor tends to be miniaturized.
