Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The motor assembly is connected to the driven device and is used for driving the driven device. For convenience of description, the motor assembly is hereinafter exemplified for a washing machine, and a portion of the washing machine excluding the motor assembly is a driven device. The washing machine comprises a washing machine shell, a washing machine roller arranged in the washing machine shell and a motor for driving the washing machine roller to rotate. In order to be convenient for install the motor to the washing machine casing, current motor for washing machine all directly goes out the installation stabilizer blade on the motor casing integrated into one piece, thereby assembles the assembly that realizes the motor through the mounting structure on installation stabilizer blade and the washing machine casing.

However, since different washing machine models of different washing machine manufacturers, the internal construction of the washing machines is different. The positions of the mounting structures of the motor inside the washing machine housing are different. Illustratively, when there are three mounting structures on the washing machine housing (there may be one, two, four or more mounting structures in other embodiments), there are three connecting legs on the motor housing, and after the motor is mounted on the washing machine housing, the three connecting legs are respectively connected with the three mounting structures. However, for other manufacturers, the relative distances of the three mounting structures on the housing of the washing machine are changed, so that the original motor cannot be mounted. Because the connection support leg on the motor shell is integrally formed with the motor shell, the motor shell needs to be redesigned to realize the assembly of the motor and the washing machine. In the adjustment process, the shell of the motor needs to be re-opened, which clearly increases the production cost and the design cost of the motor.

And when the motor shell is detachably connected with the mounting support legs, relative vibration is easily generated between the motor and the mounting support legs during operation of the motor, so that noise generated during operation of the motor assembly is increased.

In view of this, referring to fig. 1-11, in one embodiment of the present utility model, a motor assembly 10 is provided, the motor assembly 10 specifically including a motor 200 and a connector 100, the connector 100 being used to mount the motor 200 to a driven device, specifically to a washing machine housing. In the actual assembly process, the motor 200 is assembled to the connection member 100 first, and the connection member 100 is assembled to the mounting structure 300 of the washing machine housing, thereby achieving the purpose of assembling the motor 200 to the washing machine housing.

Referring specifically to fig. 1-5, the motor 200 includes a motor housing 210, the motor housing 210 including a first connection portion 211. The connector 100 includes a base 110, at least one second connecting portion 120, and at least one third connecting portion 130.

The number, specific structure and arrangement position of the first connection portions 211 depend on actual requirements, and in some embodiments, referring to fig. 5 to 7, in order to improve the integrity of the appearance of the motor housing 210, and in order to improve the connection stability of the first connection portions 211, the first connection portions 211 are located on the outer peripheral side of the motor housing 210, and along a direction parallel to the rotation axis of the motor 200, one end of the first connection portions 211 is flush with the end surface of the motor housing 210 facing away from the output shaft 220, and the other end is close to the end surface of the motor housing 210 where the output shaft 220 is provided. Also, the motor housing 210 includes, illustratively, two first connection portions 211, and the two first connection portions 211 are spaced apart in a circumferential direction of the rotational axis of the motor 200.

The number of the second connection parts 120 is at least one, and specifically, the number of the second connection parts 120 may be one, two, three, four, or the like. Regardless of the number of the second connection portions 120, each of the second connection portions 120 is connected to the base 110. Each second connection portion 120 is configured to be detachably connected to the motor 200, specifically, to the first connection portion 211 of the motor housing 210. The number of the second connection parts 120 depends on the number, structure and connection requirements of the first connection parts 211. For convenience of description, the number of the second connection parts 120 is exemplified as two. The connection manner of the second connection portion 120 and the first connection portion 211 depends on actual requirements, and in some embodiments, the second connection portion 120 may be screwed or clamped with the first connection portion 211. Referring to fig. 1 and 5, in the present embodiment, the threaded connection between the second connection portion 120 and the first connection portion 211 is taken as an example. When the number of the second connection parts 120 is plural, the connection manner of each second connection part 120 and the first connection part 211 may be the same or different. For example, when the number of the second connection parts 120 is two, one of the second connection parts 120 may be screwed with the first connection part 211, and the other second connection part 120 may be clamped with the first connection part 211. In this embodiment, the connection manner of each second connection portion 120 and the first connection portion 211 is the same, and each second connection portion 120 and the first connection portion 211 are connected by screw threads.

The number of the third connection parts 130 is at least one, and specifically, the number of the third connection parts 130 may be one, two, three, four, or the like. Regardless of the number of third connecting portions 130, each third connecting portion 130 is connected to the base 110. Each third connection 130 is for connection with a driven device, specifically, each third connection 130 is for connection with a washing machine housing. The number of the third connection parts 130 may be determined according to the number of the mounting structures 300 of the washing machine housing, for example, when the number of the mounting structures 300 on the washing machine housing is two, the number of the third connection parts 130 may be two, and when the number of the mounting structures 300 on the washing machine housing is three, the number of the third connection parts 130 may be three. For convenience of description, the following is exemplified with the number of the third connection parts 130 being four (this structure may be adapted to a scheme having four mounting structures 300 on the washing machine housing).

The base 110 may or may not be connected to the motor housing 210. In the present embodiment, when the number of the second connection parts 120 is two and both the second connection parts 120 are screwed with the motor housing 210, the base 110 is not connected with the motor housing 210. Likewise, the base 110 may or may not be coupled to the washing machine housing. In the present embodiment, the base 110 may be screw-coupled with the washing machine housing when the four third coupling parts 130 are all coupled with the washing machine housing in an interference fit.

In this embodiment, after the motor 200 is connected to the connector 100, the connector 100 is connected to the washing machine housing, so that the motor 200 and the washing machine housing can be assembled. In addition, for different types of washing machines, after the positions of the two mounting structures 300 on the washing machine housing are changed (for example, the distance between the two mounting structures 300 is increased or decreased), the matching of the washing machine housing can be achieved only by adjusting the positions of the third connecting portions 130 on the connecting member 100. In addition, in the adjustment process, only the connector 100 needs to be redesigned and manufactured, so that the design workload is less and the mold opening cost is lower compared with the design workload of the prior art in which the whole motor housing 210 is redesigned and manufactured, thereby reducing the cost of the motor 200.

Also, when the assembly of the motor 200 is performed using the connector 100 in the embodiment of the present utility model, the first connection part 211 on the motor housing 210 does not need to match the mounting structure 300 on the washing machine housing, and the second connection part 120 on the connector 100 actively matches the specific structure of the first connection part 211, so that the design of the first connection part 211 on the motor housing 210 can be more free and rational.

Meanwhile, in the present embodiment, the base 110 is provided with a connection wall 1111, and after the first connection portion 211 is connected to the second connection portion 120, the outer side wall of the motor housing 210 is attached to the connection wall 1111. In this scheme, after motor 200 is connected with the connecting seat, the area of contact between motor 200 and the connecting seat is bigger to make the connection between motor 200 and the connecting seat inseparabler, reduced motor 200 for the probability of connecting seat vibration, reduced the noise that motor assembly 10 during operation produced. The portion where the motor housing 210 is attached to the connection wall 1111 depends on the actual requirement, and in some embodiments, the wall surface of the motor 200 outside the first connection portion 211 may be attached to the connection wall 1111. In other embodiments, the side wall of the first connection portion 211 of the motor housing 210 is attached to the connection wall 1111.

After the connection member 100 is connected to the motor 200, the relative position between the connection member 100 and the motor 200 depends on the actual requirement, in some embodiments, after the connection member 100 is connected to the motor 200, the connection member 100 and the motor 200 are disposed along a direction parallel to the rotation axis of the motor 200, and at this time, the first connection portion 211 of the motor housing 210 may be disposed at an end of the motor housing 210 facing away from the output shaft 220. Referring to fig. 5-7, in other embodiments, after the connection member 100 is connected to the motor 200, the connection member 100 is disposed with the motor 200 in a direction perpendicular to the rotational axis of the motor 200. Further, the first connection portion 211 of the motor housing 210 is located on the outer peripheral side of the motor housing 210.

Referring to fig. 5-7, in some embodiments, the number of second connection portions 120 is two, and the two second connection portions 120 are arranged in a spaced-apart opposition. The two second connection portions 120 are configured such that the first connection portion 211 is located between the two second connection portions 120 when the first connection portions 211 are connected, respectively. In this solution, after the first connection portion 211 is connected with the two second connection portions 120, the two second connection portions 120 can limit the displacement of the motor 200 along the direction from one of the second connection portions 120 to the other second connection portion 120, so as to improve the connection stability of the motor 200 and the connection member 100.

Further, in some embodiments, after the two second connection portions 120 are connected to the first connection portion 211, two ends of the first connection portion 211 may abut against the two second connection portions 120, respectively. In this scheme, the first connecting portion 211 can be held by the two second connecting portions 120, on the one hand, the connection stability between the two second connecting portions 120 and the first connecting portion 211 can be further improved, on the other hand, the two second connecting portions 120 can also form a predetermined position with the first connecting portion 211, so that the assembly between the two second connecting portions 120 and the first connecting portion 211 is facilitated.

When the number of the first connection parts 211 is two, in some embodiments, only one of the first connection parts 211 may be located between the two second connection parts 120 after the motor 200 is connected with the connection member 100. Referring to fig. 5-7, in other embodiments, two first connecting portions 211 may be located between two second connecting portions 120. Further, the two second connection parts 120 may commonly sandwich the two first connection parts 211.

The specific connection manner of the second connection portion 120 and the first connection portion 211 is determined according to actual needs. Referring to fig. 5-7, in some embodiments, the motor assembly 10 further includes a threaded connection 400, the threaded connection 400 configured to be threaded through the first connection 211 and the two second connections 120 such that the first connection 211 is threadably coupled to the two second connections 120. Specifically, the first connection part 211 and one of the second connection parts 120 are provided with through holes, and the other second connection part 120 is provided with a screw hole, and the screw connection 400 is screw-connected with the screw hole after passing through the two through holes, thereby fixing the two second connection parts 120 and the one first connection part 211. When the number of the first connecting portions 211 is two, and the two first connecting portions 211 are located between the two second connecting portions 120, one through hole is formed in each of the two first connecting portions 211, two through holes are formed in one of the second connecting portions 120, the two through holes in the second connecting portions 120 are in one-to-one correspondence with the through holes in the two first connecting portions 211, two threaded holes are formed in the other second connecting portion 120, and the two threaded holes in the second connecting portion 120 are in one-to-one correspondence with the through holes in the two first connecting portions 211. The connecting piece 100 comprises two threaded connecting pieces 400, and the two threaded connecting pieces 400 respectively penetrate through holes in the second connecting portion 120, through holes in the first connecting portion 211 and threaded holes in the second connecting portion 120 in a one-to-one correspondence mode.

The specific arrangement position of the connection wall 1111 depends on the actual requirement, referring to fig. 5-9, in some embodiments, the connection wall 1111 is located between two second connection portions 120, and the connection wall 1111 connects the two second connection portions 120. This solution can further facilitate the motor housing 210 to engage the connection wall 1111. Further, the base 110 is configured such that the connection wall 1111 presses against the sidewall of the first connection portion 211 when the first connection portion 211 is connected to the two second connection portions 120. That is, when the two second connection parts 120 are connected with the first connection part 211, a pressing force is generated between the first connection part 211 and the connection wall 1111, which can make the contact between the motor 200 and the base 110 tighter, reduce the vibration amplitude generated with respect to the base 110 when the motor 200 operates, and reduce the noise when the motor 200 operates.

Referring to fig. 7 to 9, when the motor 200 has two first connection portions 211, the connection wall 1111 may be simultaneously in pressing contact with the sidewalls of the two first connection portions 211. Further, when the two first connection portions 211 are spaced apart in the circumferential direction of the rotational axis of the motor 200, the motor housing 210 may further include an intermediate wall surface between the two first connection portions 211. When the motor 200 is assembled with the connector 100, the wall surfaces of the two first connecting portions 211 facing the connecting wall surface 1111 and the intermediate wall surface are attached to the connecting wall surface 1111, and positive pressure is generated between the wall surfaces of the two first connecting portions 211 facing the connecting wall surface 1111 and the intermediate wall surface and the connecting wall surface 1111.

In order to facilitate the generation of a suitable positive pressure between the motor 200 and the base 110, referring to fig. 9, in some embodiments, the base 110 further includes a cushion 111, the cushion 111 is disposed between the two second connection portions 120, and the cushion 111 includes the aforementioned connection wall 1111. The cushion pad 111 is configured such that when the first connection portion 211 is connected to the two second connection portions 120, the cushion pad is compressed by the first connection portion 211, thereby generating a pressing force against the first connection portion 211. In this scheme, during the assembly of the motor 200, the first connecting portion 211 of the motor housing 210 is first inserted between the two second connecting portions 120, the first connecting portion 211 is brought into contact with the connecting wall 1111 of the cushion pad 111, and then the motor housing 210 is pressed, so that the cushion pad 111 is continuously pressed by the first connecting portion 211 and is in a compressed state until the through hole pressed to the first connecting portion 211 is aligned with the hole on the second connecting portion 120, and then the threaded connector 400 is passed through the hole on the two second connecting portions 120 and the through hole on the first connecting portion 211, thereby fixing the relative position between the first connecting portion 211 and the two second connecting portions 120. Since the cushion pad 111 is compressed, the cushion pad 111 generates a pressing force pressing the first connection portion 211, so that the first connection portion 211 can be in close contact with the connection wall 1111 in a direction perpendicular to the rotation axis of the motor 200, vibration noise during operation of the motor 200 is reduced, and also, buffering can be generated between the motor 200 and the base 110, impact force from the motor 200 received by the base 110 is reduced, and the service life of the connector 100 is prolonged.

The connection manner of the third connection portion 130 and the washing machine housing depends on actual requirements, and in some embodiments, the third connection portion 130 may be screwed, interference fit, welded, glued, or clamped with the washing machine housing. Referring to fig. 1 to 4 and 10 to 11, in this embodiment, the interference fit connection between the third connecting portion 130 and the casing of the washing machine is taken as an example. When the number of the third connection parts 130 is plural, the connection manner of each third connection part 130 and the washing machine housing may be the same or different. For example, when the number of the third connection parts 130 is two, one of the third connection parts 130 may be screw-coupled with the washing machine housing, and the other third connection part 130 may be interference-coupled with the washing machine housing. In this embodiment, the connection modes of the third connection portions 130 and the washing machine housing are the same, that is, the four third connection portions 130 are in interference fit connection with the washing machine housing.

The specific structure of the interference fit connection between the washing machine housing and the third connecting portion 130 depends on the actual requirements. In some embodiments, the washing machine housing includes a connection hole, the third connection part 130 includes a connection post, and the third connection part 130 is inserted into the connection hole of the washing machine and is connected with the connection hole in an interference fit. In some embodiments, the third connection part 130 includes a connection hole, the washing machine housing includes a connection post, and the connection post of the washing machine housing is inserted into the connection hole of the third connection part 130 to be interference-fitted with the third connection part 130. In some embodiments, one of the mounting structures 300 of the washing machine housing comprises a connection hole, one of the third connection parts 130 comprises a connection post, and the connection post of the third connection part 130 is inserted into the connection hole of the mounting structure 300 and is in interference fit with the connection hole; the other mounting structure 300 of the washing machine housing includes a connection post, the other third connection part 130 includes a connection hole, and the connection post of the mounting structure 300 is inserted into the connection hole of the third connection part 130 and is in interference fit with the connection hole. Referring to fig. 5 to 7, in the present embodiment, the four third connection portions 130 each include a connection hole, the four mounting structures 300 of the washing machine housing each include a connection post, and the four connection posts are inserted into the four connection holes in a one-to-one correspondence and are interference fit with each other.

Referring to fig. 5-7, in some embodiments, the number of the third connection parts 130 is four, and the four third connection parts 130 are respectively located at four corners of the base 110. This scheme can make the atress of connecting piece 100 four corners position more even, and then makes the connecting piece 100 more firm with the connection of washing machine casing. And, after the four third connection parts 130 are all connected with the washing machine housing in an interference fit, the base 110 may be screw-coupled with the washing machine housing to prevent the third connection parts 130 from being separated from the mounting structure 300 of the washing machine housing. Specifically, the base 110 may be coupled with the washing machine housing using a screw, and a length direction of the screw is perpendicular to an axis direction of the coupling hole of the at least one third coupling part 130.

Considering that vibration is generated when the motor 200 is operated and is easily transmitted to the connection of the third connection part 130 and the mounting structure 300 of the washing machine housing, in order to further prevent the third connection part 130 from loosening with the mounting structure 300 of the washing machine housing, referring to fig. 5 to 7 and 10 to 11, in some embodiments, the third connection part 130 includes a sleeve 131 connected to the base 110 and a buffer sleeve 132 provided in the sleeve 131, an axis of the sleeve 131 coincides with an axis of the buffer sleeve 132, and the buffer sleeve 132 is used for interference fit with the mounting part. The buffer sleeve 132 may be in an interference fit connection with the sleeve 131, glued, etc. The material of the buffer sleeve 132 can be made of elastic materials such as silica gel or rubber, and when the motor 200 vibrates, the buffer sleeve 132 can absorb shock, so that on one hand, the probability that the mounting structure 300 of the washing machine shell is separated from the buffer sleeve 132 can be reduced, and on the other hand, the vibration amplitude effect of the washing machine shell can be reduced, and accordingly noise generated during the operation of the washing machine is reduced.

In some embodiments, the axes of the buffer jackets 132 of each third connection 130 are all arranged in parallel. In this case, the assembling of each buffer jacket 132 can be facilitated. Further, when the number of the third connecting portions 130 is four, and the four third connecting portions 130 are respectively located at four corners of the base 110, two of the buffer sleeves 132 may be arranged with their axes coincident, and the other two buffer sleeves 132 may be arranged with their axes coincident and parallel to each other.

Referring to fig. 5-7, in some embodiments, each second connection portion 120 is connected to one side of the base 110 (which may be disposed on the lower side of the base 110 in a specific product), and each third connection portion 130 is connected to the opposite side of the base 110 (which may be disposed on the upper side of the base 110 in a specific product). In this scheme, can make connecting piece 100 connect motor 200 and washing machine casing back respectively, connecting piece 100 is located motor 200 and washing machine casing centre, and connecting piece 100 can play certain cushioning effect to reduce the vibrations of motor 200 conduction to the washing machine casing on, and then reduce washing machine's operational noise. In other embodiments, each second connecting portion 120 and each third connecting portion 130 may be located on the same side of the base 110, such that after the connecting member 100 is connected to the motor 200 and the washing machine housing respectively, the connecting member 100 is located on a side of the motor 200 facing away from the washing machine housing.

Referring to fig. 10, in some embodiments, when the connection member 100 is connected to the motor 200, the connection member 100 has two third connection portions 130 distant from the output shaft 220 of the motor 200 and two third connection portions 130 close to the output shaft 220 of the motor 200. Wherein, the inner holes of the buffer sleeves 132 of the third connecting portion 130 close to the output shaft 220 of the motor 200 are cylindrical, and the inner holes of the buffer sleeves 132 of the third connecting portion 130 far away from the output shaft 220 of the motor 200 are truncated cone-shaped, and the cross-sectional area of the inner holes of the output shaft 220 far away from the motor 200 is smaller. In this solution, since the inner hole of the buffer sleeve 132 close to the output shaft 220 of the motor 200 is cylindrical, when the motor 200 vibrates, displacement along the direction parallel to the axis of the inner hole is not easy to occur between the buffer sleeve 132 and the mounting structure 300 of the washing machine housing, so that the buffer sleeve 132 is not easy to separate from the washing machine housing. The inner hole of the buffer sleeve 132 far from the output shaft 220 of the motor 200 is in a circular truncated cone shape, so that the assembly accuracy of the connecting piece 100 can be reduced, and when the relative position of each third connecting portion 130 and the relative position of each mounting structure 300 of the washing machine shell are slightly misplaced, the connecting piece 100 can still be well assembled, and the processing cost of the connecting piece 100 is reduced.

Referring to fig. 11, in some embodiments, when the connection member 100 is connected to the motor 200, the connection member 100 has two third connection portions 130 distant from the output shaft 220 of the motor 200 and two third connection portions 130 close to the output shaft 220 of the motor 200. Wherein, the inner holes of the buffer sleeves 132 of the third connecting portion 130 close to the output shaft 220 of the motor 200 are cylindrical, and the inner holes of the buffer sleeves 132 of the third connecting portion 130 far away from the output shaft 220 of the motor 200 are truncated cone-shaped, and the cross-sectional area of the inner holes of the output shaft 220 far away from the motor 200 is larger. In this solution, when the motor 200 vibrates, since the hole wall of the inner hole of the buffer sleeve 132 far away from the output shaft 220 of the motor 200 faces the output shaft 220 of the motor 200, displacement along the hole axis direction parallel to the inner hole is less likely to occur between the buffer sleeve 132 and the mounting structure 300 of the washing machine housing, so that the third connecting portion 130 far away from the output shaft 220 of the motor 200 is less likely to be separated from the mounting structure 300 of the washing machine housing, and the connection stability of the connecting piece 100 is improved.

The embodiment of the third aspect of the present utility model further provides a washing machine comprising the motor assembly 10 of any of the above embodiments and a washing machine housing to which the connector 100 is connected in the manner of the connection of any of the above embodiments.
