Description

Technical Field

[0001] The utility model relates to the technical field of washing machine motors, in particular to a washing machine motor structure with a shock absorbing function. Background Art

[0002] The motor housing of a washing machine generally refers to the outer casing of all electrical motor equipment. The motor housing is a protective device for the motor. It is made of silicon steel sheets and other materials using stamping and deep drawing processes. In addition, surface anti-rust and plastic spraying processes can well protect the internal equipment of the motor.

[0003] For example, a combined washing machine motor housing with publication number CN212323849U comprises an end cover and a bottom cover, wherein the lower end of the end cover is integrally formed with an end cover plate, and the upper end of the bottom cover is integrally formed with a bottom cover plate, a positioning mechanism is connected between the end cover plate and the bottom cover plate, and the positioning mechanism comprises a positioning sleeve, a limiting cylinder and a bolt, wherein the positioning sleeve is respectively welded to the lower surface of the end cover plate and the upper surface of the bottom cover plate, and a movable groove is provided inside the positioning sleeve, and the limiting cylinder is inserted into the inside of the movable groove; by installing the positioning mechanism between the end cover plate and the bottom cover plate, the convenience of adjusting the distance between the end cover plate and the bottom cover plate is increased, and at the same time, both ends of the limiting cylinder are inserted into the inside of the movable groove, and at the same time, a buffer spring is installed in the inside of the movable groove, so that the limiting plate at one end of the buffer spring is in close contact with the surface of the limiting cylinder, which increases the flexibility of adjusting the distance between the limiting cylinder inserted into the movable groove;

[0004] The above-mentioned combined washing machine motor housing can improve the flexibility of adjustment by installing a positioning mechanism between the end cover plate and the bottom cover plate. However, the washing machine motor also needs a housing for protection. The washing machine has a high probability of leakage, which will cause the housing to become damp and rot for a long time, causing damage to the internal motor. At the same time, there is often a collision between the motor and the housing, emitting a high noise. Utility Model Content

[0005] The utility model aims to provide a washing machine motor structure with a shock-absorbing function, so as to solve the problem in the background technology that the washing machine has a high probability of water leakage, which will cause the outer shell to become damp and rot for a long time, resulting in damage to the internal motor.

[0006] To achieve the above object, the utility model provides the following technical solution: a washing machine motor structure with a shock absorbing function, comprising a housing and a motor body arranged inside the housing, and a mounting bolt is installed through the left side of the housing;

[0007] A positioning rod is fixedly installed inside the housing, and a shock-absorbing protection mechanism is provided on the surface of the positioning rod, and the shock-absorbing protection mechanism performs buffering and protection on the motor body by sliding along the surface of the positioning rod;

[0008] An airbag is provided through the surface of the positioning rod, and the right side of the airbag is fixedly installed inside the shell, and a sealing and waterproof mechanism is provided on the right side of the airbag, and the sealing and waterproof mechanism is pressed by the airbag to improve the sealing effect.

[0009] Furthermore, mounting grooves are provided at the upper and lower ends of the left side of the shell, and the mounting grooves are arc-shaped, and mounting bolts are provided through the interior of the mounting grooves.

[0010] Furthermore, the shock-absorbing protection mechanism is provided with a moving block, and the moving block is installed through the surface of the positioning rod, and a rotating rod is rotatably installed on the inner side of the moving block, and the inner side of the rotating rod is rotatably installed on the outer side of the motor body. The shock-absorbing protection mechanism is set into three groups, and the shock-absorbing protection mechanism is located on the left side and the upper and lower sides of the motor body.

[0011] Furthermore, a return spring is nested and installed on the surface of the positioning rod, and the left and right ends of the return spring are fixedly installed between the moving block and the shell, and a damping hydraulic support rod is bolted between the shell and the motor body.

[0012] Furthermore, the sealing and waterproof mechanism is provided with an air duct, and the left side of the air duct is installed through the right side of the airbag, and the lower end of the air duct is fixedly installed with a wear-resistant inflatable sealing strip, and the wear-resistant inflatable sealing strip is arranged between the output end of the motor body and the shell.

[0013] Furthermore, the airbag is made of elastic material, and the airbag and the moving block form a pressed structure, and the airbag forms a connecting structure with the wear-resistant inflation sealing strip through an air guide tube, and a one-way air inlet is installed through the outside of the airbag, and a one-way valve is arranged inside the one-way air inlet.

[0014] Furthermore, the shell is bonded with an inner sound insulation layer, and the outer side of the shell is bonded with an outer sound insulation layer, and the outer side of the outer sound insulation layer is bonded with a waterproof layer, and the outer side of the waterproof layer is bonded with an anti-corrosion layer.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. A mounting groove capable of stable installation is provided. A housing is provided on the outside of the motor body. Mounting grooves are provided at both the upper and lower ends of the housing. The mounting grooves are arranged in an arc shape. Mounting bolts can be provided at both the left and right ends of the mounting grooves, which can improve the installation stability of the device.

[0017] Furthermore, a buffering component is provided between the housing and the motor body. When the motor body shakes, the motor body applies pressure to the rotating rod. Since both ends of the rotating rod are rotatably mounted, the rotating rod applies pressure to the moving block, so that the moving block slides along the positioning rod to squeeze the return spring. When the return spring is squeezed, it buffers through its own elastic force, thereby achieving a buffering protection effect, preventing the motor body from shaking and hitting the housing, preventing internal parts from being damaged when the motor shakes and hits the housing, and improving the service life of the device.

[0018] Furthermore, a damping hydraulic support rod is provided between the housing and the motor body. When the damping hydraulic support rod supports the motor body, after the return spring performs buffering, the return spring itself will generate a reciprocating vibration force. At this time, the damping hydraulic support rod is used to release pressure to avoid the reciprocating vibration of the return spring, thereby achieving a shock absorbing effect, realizing a shock absorbing function, further protecting the motor body, and improving the durability of the device.

[0019] 2. A wear-resistant inflatable sealing strip is provided between the housing and the output end of the motor body. The wear-resistant inflatable sealing strip seals the housing and the output end of the motor body. At the same time, when the motor body shakes, the moving block slides along the positioning rod, which can squeeze the airbag back and forth. The airbag delivers the internal air to the wear-resistant inflatable sealing strip through the air guide tube. The wear-resistant inflatable sealing strip expands to improve the sealing effect, which can further seal the interior of the housing. The airbag takes in air through the one-way air inlet. The one-way valve inside the one-way air inlet is set so that the airbag can only take in air through the one-way air inlet, and cannot be exhausted through the one-way air inlet, thereby preventing water inside the washing machine from leaking into the motor and achieving a waterproof effect.

[0020] Furthermore, sound insulation layers are provided inside and outside the shell. The provision of the inner sound insulation layer and the outer sound insulation layer can reduce the noise generated by the motor body during operation and can effectively avoid noise pollution. At the same time, a waterproof layer is provided on the outside of the outer sound insulation layer. The waterproof layer can improve the waterproof effect of the shell and prevent water leaked from the washing machine from entering the shell and causing damage to the motor body inside the shell. In conjunction with the anti-corrosion layer on the outside of the waterproof layer, water leaked from the washing machine can be prevented from corroding the shell, thereby improving the service life of the shell and avoiding the phenomenon of dampness and rot on the shell surface after long-term use of the washing machine.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 and Figure 2 The technical solution shown, in order to solve the problem of unstable installation of the washing machine shell, discloses a stable installation mechanism: a shell 1 and a motor body 2 arranged inside the shell 1, and a mounting bolt 4 is installed through the left side of the shell 1, and mounting grooves 3 are opened at the upper and lower ends of the left side of the shell 1, and the shape of the mounting groove 3 is an arc shape, and the mounting bolt 4 is installed through the inside of the mounting groove 3;

[0031] In this example, a mounting groove 3 for stable installation is provided, a housing 1 is provided on the outside of the motor body 2, the upper and lower ends of the housing 1 are provided with mounting grooves 3, the mounting grooves 3 are arranged in an arc shape, and mounting bolts 4 can be arranged on both the left and right ends of the mounting grooves 3. The housing 1 can be installed inside the washing machine through the mounting grooves 3 and the mounting bolts 4, and the installation stability of the device can be improved; Example

[0032] like Figure 2 , Figure 3 and Figure 4The technical solution shown, in order to solve the problem that the washing machine motor is easily shaken and damaged, discloses a shock-absorbing protection mechanism: a positioning rod 5 is fixedly installed inside the shell 1, and a shock-absorbing protection mechanism is arranged on the surface of the positioning rod 5, and the shock-absorbing protection mechanism performs buffering and protection on the motor body 2 by sliding along the surface of the positioning rod 5, the shock-absorbing protection mechanism is provided with a moving block 6, and the moving block 6 is installed through the surface of the positioning rod 5, and a rotating rod 7 is rotatably installed on the inner side of the moving block 6, and the inner side of the rotating rod 7 is rotatably installed on the outer side of the motor body 2, the shock-absorbing protection mechanism is arranged in three groups, and the shock-absorbing protection mechanism is located on the left side and the upper and lower sides of the motor body 2, a reset spring 8 is nested and installed on the surface of the positioning rod 5, and the left and right ends of the reset spring 8 are fixedly installed between the moving block 6 and the shell 1, and a damping hydraulic support rod 9 is bolted between the shell 1 and the motor body 2;

[0033] When the motor body 2 is shaken, the motor body 2 applies pressure to the rotating rod 7. The rotating rod 7 is subjected to pressure because both ends are rotatably installed. Therefore, the rotating rod 7 applies pressure to the moving block 6, so that the moving block 6 slides along the positioning rod 5 to squeeze the return spring 8. When the return spring 8 is squeezed, it is buffered by its own elastic force, thereby achieving the effect of buffer protection, avoiding the motor body 2 from shaking and hitting the housing 1, and preventing the internal parts from being damaged when the motor body 2 shakes and hits the housing 1, thereby improving the service life of the device. A damping hydraulic support rod 9 is provided between the housing 1 and the motor body 2. While the damping hydraulic support rod 9 supports the motor body 2, when the return spring 8 is buffered, the return spring 8 itself will generate a reciprocating vibration force. At this time, the damping hydraulic support rod 9 is used to release pressure to avoid the reciprocating vibration of the return spring 8, thereby achieving the effect of shock absorption, realizing the shock absorption function, further protecting the motor body 2, and improving the durability of the device.

[0035] In this example, a wear-resistant inflatable sealing strip 12 is provided between the shell body 1 and the output end of the motor body 2. The wear-resistant inflatable sealing strip 12 seals the shell body 1 and the output end of the motor body 2. At the same time, when the motor body 2 shakes, the moving block 6 slides along the positioning rod 5, and can squeeze the airbag 10 back and forth.

The one-way valve inside the one-way air inlet 13 is set, so that the inside of the airbag 10 can only take in air through the one-way air inlet 13, and cannot exhaust air through the one-way air inlet 13. This can prevent water from leaking into the motor from the washing machine, thus achieving a waterproof effect. Sound insulation layers are provided inside and outside the shell 1. The provision of the inner sound insulation layer 15 and the outer sound insulation layer 14 can reduce the noise generated by the motor body 2 during operation, and can effectively avoid noise pollution.
