Description

Technical Field

[0001] The utility model relates to the technical field of washing machine drum shock absorbing parts, and more specifically, to a shock absorbing suspension device for a drum washing machine. Background Art

[0002] A drum washing machine mainly relies on the regular forward, reverse or continuous rotation of the drum to drive the clothes to tumble in the washing tub. Through mutual collision and friction, and under the action of detergent, the dirt is separated from the clothes, thereby achieving the purpose of cleaning the clothes.

[0003] As the core component of the machine body, the drum is mainly installed in the inner cavity of the machine body and is limited by a cylindrical shell. The drum is driven by a motor to roll. When the drum rolls, a certain force is generated, causing the drum to shake as a whole. In view of this, the bottom and top of the drum need to be respectively provided with a shock-absorbing damping seat body and a component that can provide shock-absorbing suspension for the drum to buffer the force generated by the drum during operation, thereby reducing the vibration of the drum to the machine body;

[0004] The shock-absorbing suspension components used in the drum are mostly medium-to-large torsion springs. By fixing the torsion springs to the machine body cavity wall and the outer wall of the drum shell respectively, the vibration generated during the operation of the drum will be buffered by the torsion springs. Since the force generated by the drum is an omnidirectional force, the vibration direction of the drum caused by the force is also irregular. When the rigidly connected shock-absorbing suspension component is subjected to the force, its torsion spring will also deform to a certain extent along the direction of the force. The spring in this state, on the one hand, cannot achieve the best shock-absorbing effect of the torsion spring in the linear state. On the other hand, long-term high-frequency vibration will also cause elastic attenuation, and severe damage to the spring will also occur, reducing the service life.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a shock-absorbing suspension device for a drum washing machine. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a shock-absorbing suspension device for a drum washing machine.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shock-absorbing suspension device for a drum washing machine, comprising a shock-absorbing assembly and a suspension assembly threadedly connected to both ends of the shock-absorbing assembly for fine-tuning the angle of the shock-absorbing assembly; wherein the shock-absorbing assembly comprises a shock-absorbing spring and a disc body connecting piece arranged at both ends of the shock-absorbing spring, the disc body connecting piece is a double-disc combination structure, and the double discs can rotate independently, and the disc body connecting piece is provided with a limit piece for limiting the threaded connection between the shock-absorbing assembly and the suspension assembly; the suspension assembly comprises a connecting plate and a carrier plate, the carrier plate is provided with a mounting plate with an integrated structure, the mounting plate is provided with a ball-type connecting piece and a limit spring connected to the connecting plate, the limit spring is provided with multiple groups and is evenly distributed on the edge of the ball-type connecting piece, and is used to buffer the force generated when the ball-type connecting piece drives the connecting plate to swing at multiple angles.

[0008] Preferably, the disk connecting member includes a second disk connected to the shock absorbing spring and a first disk connected to the second disk for limited rotation. The first disk and the second disk are disks with the same diameter, and a threaded end is provided on the first disk.

[0009] Preferably, a ring sleeve for limiting the threaded connection of the disk body connector is provided at the center of the top surface of the connecting plate, limiting holes are symmetrically provided on the ring sleeve, and a threaded interface connected to the threaded end is provided at the center of the inside of the ring sleeve.

[0010] Preferably, the ring sleeve and the threaded interface are annular structures with different diameters and the same height, and the diameter of the ring sleeve is the same as the diameter of the first disk body.

[0011] Preferably, the ball-type connector includes a ball sleeve fixed on the mounting plate and a ball head confined in the ball sleeve, the ball sleeve is a semi-closed structure, and a connecting port is provided on the top of the ball sleeve, and the ball head is fixed to the bottom surface of the connecting plate through the connecting port.

[0012] Preferably, the limiting members are provided with two groups, and the two groups of limiting members are symmetrically arranged on the side wall of the first disk body, and the limiting members include a rotating end head and a strip plate; wherein the rotating end head is in a cylindrical structure and is rotatably connected to the side wall of the first disk body, and two groups of strip blocks are arranged on the circular surface of the end opposite to the rotating connection end of the rotating end head; the strip plate is rotatably connected between the two groups of strip blocks, and the end opposite to the rotating connection end of the strip plate is provided with a limiting buckle engaged with the limiting hole, and a rubber sleeve is nested on the limiting buckle.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The shock-absorbing suspension device of the utility model, through the cooperation of the ball-type connector and multiple groups of limit springs between the shock-absorbing assembly and the suspension assembly, can adaptively fine-tune the overall position of the shock-absorbing assembly according to the direction of the force when the device is affected by the force, so that the shock-absorbing spring of the shock-absorbing assembly always maintains a linear state when the position changes, thereby achieving the best shock-absorbing effect. At the same time, this method also avoids the situation where the spring is excessively twisted due to the influence of the force, causing elastic attenuation and damage.

[0015] 2. In the shock-absorbing suspension device of the utility model, a threaded matching limiter combination structure is adopted between the shock-absorbing assembly and the suspension assembly to achieve connection. The limiter adopts a radially adjustable rotating end and a strip plate. When locking, after the thread is locked, the limit can be achieved by fitting the limit buckle on the strip plate into the corresponding limit hole on the ring sleeve. When disassembling, the lock of the strip plate is released and its position is adjusted to make it act as a lever, which can be manually operated by the lever. Therefore, the combination of the threaded matching limiter not only realizes the locking and limiting function of the shock-absorbing assembly and the suspension assembly, but also provides a certain convenience for the disassembly and assembly of the two, thereby achieving a dual-use effect.

[0028] like Figure 1-6 As shown, the utility model provides a shock-absorbing suspension device for a drum washing machine, comprising a shock-absorbing component 1 and a suspension component 2 threadedly connected to both ends of the shock-absorbing component 1 for fine-tuning the angle of the shock-absorbing component 1;

[0029] The shock absorbing assembly 1 comprises a shock absorbing spring 101 and a disc body connecting member arranged at both ends of the shock absorbing spring 101. The disc body connecting member is a double disc combination structure, and the double discs can rotate independently. The disc body connecting member is provided with a limiting member 5 for limiting the threaded connection between the shock absorbing assembly 1 and the suspension assembly 2.

[0030] The suspension assembly 2 includes a connecting plate 3 and a carrier plate 4. The carrier plate 4 is provided with a mounting plate 401 of an integrated structure. The mounting plate 401 is provided with a ball-type connector and a limit spring 403 connected to the connecting plate 3. The limit spring 403 is provided in multiple groups and is evenly distributed on the edge of the ball-type connector to buffer the force generated when the ball-type connector drives the connecting plate 3 to swing at multiple angles.

[0031] In summary, the shock-absorbing suspension device mainly consists of two parts, namely, the shock-absorbing assembly 1 and the suspension assembly 2. The shock-absorbing assembly 1 is connected to the shock-absorbing assembly 1 through a ball-type connector in cooperation with the limit spring 403, so that the shock-absorbing assembly 1 can be adaptively adjusted when subjected to forces in different directions. During the adjustment process, the shock-absorbing spring 101 is still kept in a linear state, thereby achieving the best shock-absorbing effect.

[0032] Specifically, the suspension components 2 located at both ends of the shock-absorbing component 1 are respectively connected to the outer wall of the washing machine drum shell and the inner wall of the washing machine cavity. At the same time, the shock-absorbing suspension device is provided with multiple groups, which are installed accordingly according to the size of the drum to achieve the effect of stable support for the drum. When the drum runs at different frequencies, the shell will be affected by the drum and vibrate. The force generated by the vibration will be transmitted to the suspension component 2 at one end of the shock-absorbing component 1. The suspension component 2 drives the connecting plate 3 to move adaptively according to the direction of the force. At the same time, the suspension component 2 at the other end of the shock-absorbing component 1 will also be affected by the force transmission and will be adjusted accordingly with the corresponding suspension component 2. The shock-absorbing spring 101 is between the two groups of suspension components. Under the influence of the ball-type connector 2, the overall position of the following connecting plate 3 is adjusted. During the adjustment process, the shock-absorbing spring 101 body will be in a linear state. By maintaining the expansion and contraction of the shock-absorbing spring 101 in a linear state, the force generated by the roller can be buffered. In the process of adjusting the position of the ball-type connector under the force, the limit spring 403 will be elastically stretched and buffered. While protecting the ball-type connector, part of the force can also be buffered. The limit spring 403 is a small torsion spring, while the shock-absorbing spring 101 is a large torsion spring. The limit spring 403 is mainly used to reduce the hard buffering generated during the multi-angle swing of the ball head 404 in the ball-type connector.

[0033] In order to facilitate the disassembly and assembly between the shock absorbing component 1 and the suspension component 2, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the specific overview is as follows: the disc body connectors arranged at both ends of the shock absorbing spring 101 mainly include a second disc body 103 connected to the shock absorbing spring 101 and a first disc body 102 limitedly rotatably connected to the second disc body 103, the first disc body 102 and the second disc body 103 are disc bodies with the same diameter length, and a threaded end 104 is arranged on the first disc body 102;

[0034] Based on the above, it is further explained that the disc body connecting member adopts a double disc structure, and the disc bodies adopt an independent rotation structure. For details, please refer to Figure 2 As shown, the first plate 102 and the second plate 103 are connected by an annular groove and an annular buckle, and the effect of limited rotation is achieved, wherein the second plate 103 is mainly used to install the shock absorbing spring 101, and the first plate 102 rotates on the second plate 103. The shock absorbing assembly 1 can be disassembled and assembled as a whole without disassembling the suspension assembly 2 through the limiting member 5, which provides convenience for its replacement and maintenance. The two plates are of the same size, mainly to ensure the consistency of appearance, structure and overall structure;

[0035] Meanwhile, the threaded connection between the damping assembly 1 and the suspension assembly 2 is mainly realized by the independent rotation of the first plate 102 and the threaded end 104. For the connection structure corresponding to the threaded end 104 on the suspension assembly 2, refer to Figure 1 and Figure 4 , specifically described as follows, a ring sleeve 301 for limiting the threaded connection of the disk body connector is provided at the center of the top surface of the connecting plate 3, and a limiting hole 303 is symmetrically provided on the ring sleeve 301, and a threaded interface 302 connected to the threaded end 104 is provided at the center of the inner part of the ring sleeve 301;

[0036] In the above content, the part connecting the suspension component 2 and the first disk body 102 is the connecting plate 3, and the threaded connection is realized through the threaded interface 302 corresponding to the threaded end 104 on the connecting plate 3, that is, the locking and fixing effect is achieved. At the same time, in order to facilitate manual disassembly and assembly between the shock absorbing component 1 and the suspension component 2, the independent rotation characteristic of the first disk body 102 is utilized, and the limiting member 5 is cooperated to realize the disassembly and assembly between the shock absorbing component 1 and the suspension component 2 without changing the position of the shock absorbing spring 101, so as to achieve the effect of independent disassembly and assembly between the two. At the same time, the limiting connection between the limiting member 5 and the ring sleeve 301 can ensure the firmness and stability of the two after being locked;

[0037] The above-mentioned ring sleeve 301 and the threaded interface 302 are annular structures with different diameters and the same height. The diameter of the ring sleeve 301 is the same as the diameter of the first disk body 102. After the first disk body 102 and the ring sleeve 301 are screwed together, they will be completely attached to the ring sleeve 301. At the same time, the ring sleeve 301 and the threaded interface 302 of the same height ensure that when the threaded end 104 and the threaded interface 302 are screwed together, the first disk body 102 and the ring sleeve 301 are in a fitted state, forming a matching and corresponding overall structure.

[0038] In order to realize that the shock absorbing spring 101 can adaptively move in the direction of the force and be in a linear state as a whole when subjected to forces in different directions, please refer to Figure 1 , Figure 4 and Figure 5 As shown, the specific description is as follows: the ball-type connector includes a ball sleeve 402 fixed on the mounting plate 401 and a ball head 404 limited in the ball sleeve 402. The ball sleeve 402 is a semi-closed structure, and a connection port is provided on the top of the ball sleeve 402. The ball head 404 is fixed to the bottom surface of the connecting plate 3 through the connection port;

[0039] The ball-type connector can drive the connecting plate 3 to move adaptively in the direction of the force, that is, the damping spring 101 is moved as a whole, so as to achieve the effect of matching and adapting the damping spring 101 to the force;

[0040] In order to achieve the limit fixation between the shock absorbing assembly 1 and the suspension assembly 2 after the connection, and also to achieve the effect of acting as a lever when the shock absorbing assembly 1 and the suspension assembly 2 are disassembled, refer to Figure 4 and Figure 6 As shown, it is further explained that there are two groups of limit members 5, and the two groups of limit members 5 are symmetrically arranged on the side wall of the first plate body 102, and the limit members 5 include a rotating end 501 and a strip plate 503;

[0041] The rotating end 501 is cylindrical and rotatably connected to the side wall of the first disk 102. Two groups of bar blocks 502 are arranged on the circular surface of the opposite end of the rotating end 501.

[0042] The strip plate 503 is rotatably connected between the two groups of strip blocks 502. A limit buckle 504 engaged with the limit hole 303 is provided at the end of the strip plate 503 opposite to the rotatable connection end. A rubber sleeve is embedded on the limit buckle 504.

[0043] In combination with the above-mentioned description of the rotating end 501 and the strip plate 503, it is further explained that the rotating end 501 is in a transverse rotation state relative to the first disk body 102, and the strip plate 503 is based on the rotating end 501 and rotates longitudinally on the rotating end 501. Therefore, the strip plate 503 can cooperate with the rotating end 501 to perform multi-angle radial rotation. Therefore, when the shock absorbing component 1 and the suspension component 2 are threadedly locked, the limiting buckle 504 with a rubber sleeve on the strip plate 503 is engaged with the limiting hole 303, so as to achieve a limiting effect on the thread locking. When the shock absorbing component 1 and the suspension component 2 are disassembled, the position of the strip plate 503 is adjusted to act as a lever, and manual operation can be performed through the strip plate 503.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
