Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly relates to a shock absorption device and a laundry treatment device. Background Art

[0002] To reduce the vibration amplitude of the tub assembly during rotation, a shock absorption device is usually provided between the tub assembly and the cabinet of the laundry treatment device.

[0003] In the related art, the shock absorption device is composed of a shock absorption cylinder and a shock absorption rod. At least part of the shock absorption rod extends into the shock absorption cylinder and can move along the length direction of the shock absorption cylinder. When vibration occurs, the shock absorption rod moves accordingly. Through the friction between the shock absorption rod and the inner wall of the shock absorption cylinder, a damping effect can be achieved to reduce the vibration of the tub assembly. The assembly of the shock absorption device is usually to fix one end of it on one of the cabinet and the tub assembly first, then install the tub assembly into the cabinet, and then connect the other end of the shock absorption device to the other one of the cabinet and the tub assembly through fasteners. However, due to the small bottom space of the cabinet and the large number of components installed, the installation direction of the fasteners is likely to interfere with the components installed at the bottom, resulting in difficult installation of the shock absorption device and affecting its installation efficiency.

[0042] The realization of the purpose of this application, its functional features and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0044] The embodiment of this application provides a shock absorption device 100 to solve the problem that the installation of traditional shock absorption devices is relatively difficult. The following will be described in conjunction with the accompanying drawings.

[0045] In the embodiment of this application, as Figure 1 shown, the shock absorption device 100 includes a sleeve member 1 and a rod member 2. The sleeve member 1 has a shock absorption cavity 403 extending along the length direction of the sleeve member 1, and the shock absorption cavity 403 has a first opening located at one end of the sleeve member 1; the rod member 2 is detachably installed on the sleeve member 1 and has a connected state connected to the sleeve member 1 and a separated state separated from the sleeve member 1; when the rod member 2 is in the connected state, at least a part of the rod member 2 extends into the shock absorption cavity 403 from the first opening and is reciprocally movably arranged along the length direction of the sleeve member 1 and is in sliding fit with the inner wall of the shock absorption cavity 403; wherein, at least one of the sleeve member 1 and the rod member 2 is configured to be length-adjustable.

[0046] The shock absorption device 100 provided by this application is designed to be a detachable structure, which is simple to assemble and can play a role in damping shock absorption. When this shock absorption device 100 is used in a laundry treatment device, the sleeve member 1 and the rod member 2 in the separated state can be respectively installed on the cabinet and the tub assembly first, and the length of at least one of them can be shortened. After the tub assembly is assembled into the cabinet, the lengths of the sleeve member 1 and / or the rod member 2 are stretched and the two are connected, so that the assembly of the shock absorption device 100 can be realized. The installation difficulty is small, the operation is simple, and interference with the components installed at the bottom of the cabinet can be avoided, which helps to improve the assembly efficiency.

[0047] Please refer to Figure 2 and Figure 3 , the sleeve member 1 is generally in the shape of a straight sleeve, and the length direction of the sleeve member 1 is consistent with the direction of its central axis. For the convenience of description, its two ends are respectively defined as the head end and the tail end. As Figure 4As shown, a shock-absorbing cavity 403 is formed inside the sleeve member 1. The shock-absorbing cavity 403 extends along the length direction of the sleeve member 1 and penetrates through the tail end of the sleeve member 1 to form a first opening. The shock-absorbing cavity 403 is used to install the rod member 2 and provide a space for the rod member 2 to slide telescopically.

[0048] Please refer to Figure 3 , the rod member 2 is generally rod-shaped, and the length direction of the rod member 2 is consistent with the direction of its central axis. For the convenience of description, the two ends of the rod member 2 arranged oppositely in the length direction are respectively defined as the first end and the second end. The rod member 2 is used to cooperate with the sleeve member 1. In the shock-absorbing device 100 proposed in the present application, the connection relationship between the rod member 2 and the sleeve member 1 is detachable. Therefore, the rod member 2 has a connected state and a separated state: when the rod member 2 is in the separated state, there is no connection relationship between the rod member 2 and the sleeve member 1, and the two exist as two independent separated components; when the rod member 2 is in the connected state, the first end of the rod member 2 extends into the shock-absorbing cavity 403 from the first opening, and the second end extends out of the shock-absorbing cavity 403 from the first opening. In this state, the rod member 2 can be reciprocally movably arranged along the length direction of the sleeve member 1 and slidably cooperate with the inner wall of the shock-absorbing cavity 403. When the rod member 2 slidably cooperates with the inner wall of the shock-absorbing cavity 403, the friction force between the two can form a resistance to play a shock-absorbing role.

[0049] It can be understood that since the rod member 2 can move relative to the sleeve member 1, the total length of the shock-absorbing device 100 can be adjusted. When vibration occurs, the rod member 2 can move relatively closer to or away from the sleeve member 1 to achieve shock absorption.

[0050] For the convenience of installing the sleeve member 1 and the rod member 2, in some embodiments, a first joint 301 is formed at the head end of the sleeve member 1 away from the shock-absorbing cavity 403, and the first joint 301 is used to connect to one of the box body and the barrel assembly; in the rod member 2, the first end cooperates with the shock-absorbing cavity 403, and the second end is arranged opposite to the first end. A second joint 201 is formed at the second end, and the second joint 201 is used to connect to the other of the box body and the barrel assembly. Specifically, the first joint 301 and the second joint 201 can be designed as through-hole structures. During actual installation, the first joint 301 and the second joint 201 can be installed through fasteners such as bolts and pins.

[0051] In some embodiments, the length of the sleeve member 1 is set to be adjustable, so that the sleeve member 1 can have a first length and a second length, and the first length is less than the second length. In this way, by shortening the length of the sleeve member 1, the total length of the sleeve member 1 and the rod member 2 can be shortened, making it less than the length L0 of the installation space. When the shortened sleeve member 1 and the rod member 2 are respectively installed at both ends of the installation space, since their total length can be less than L0, the sleeve member 1 and the rod member 2 can face each other in a straight line without interference. Then, by extending the sleeve member 1, the rod member 2 can be inserted into the shock absorption cavity 403 to achieve their assembly.

[0052] In other embodiments, the length of the rod member 2 is set to be adjustable, so that the rod member 2 can have a third length and a fourth length, and the third length is less than the fourth length. In this way, by shortening the length of the rod member 2, the total length of the sleeve member 1 and the rod member 2 can be shortened, making it less than the length L0 of the installation space. When the shortened rod member 2 and the sleeve member 1 are respectively installed at both ends of the installation space, their total length can be less than L0, so that the sleeve member 1 and the rod member 2 can face each other in a straight line without interference. Then, by extending the rod member 2, the rod member 2 can be inserted into the shock absorption cavity 403 to achieve their assembly.

[0053] In still other embodiments, the lengths of both the sleeve member 1 and the rod member 2 are adjustable. Thus, when installing the shock absorption device 100, the sleeve member 1 and the rod member 2 can be shortened first, and then the shortened rod member 2 and the shortened sleeve member 1 are respectively installed at both ends of the installation space. At this time, their total length can be less than L0, so that the sleeve member 1 and the rod member 2 can face each other in a straight line. Then, by extending the rod member 2 and / or the sleeve member 1, the rod member 2 can be inserted into the shock absorption cavity 403 to achieve their assembly.

[0054] To achieve the adjustable length of the sleeve member 1 and / or the rod member 2, the component can be designed to include two connecting parts. One of the connecting parts forms an inner cavity with an open end, and the other connecting part extends into the inner cavity from the open end and can move relatively away from or close to it. When the other connecting part moves relatively closer, the length of the component shortens, and when the other connecting part moves relatively farther away, the length of the component extends. The "component" in the above text refers to the component designed with an adjustable length, which can be the sleeve member 1 or the rod member 2, and the present application makes no limitation. Hereinafter, the sleeve member 1 will be taken as an example for detailed description. It can be understood that the structural designs related to the adjustable length of the sleeve member 1 hereinafter can all be applied to the rod member 2.

[0055] Please refer to Figure 4 , in some embodiments, the sleeve member 1 includes a first connecting part 3 and a second connecting part 4. As Figure 5 and Figure 6As shown, the first connecting member 3 is formed with a movable cavity 304. One end of the movable cavity 304 is provided with a second opening, which is formed at the end of the first connecting member 3 and is formed by the movable cavity 304 penetrating through the first connecting member 3. The movable cavity 304 is used for installing the second connecting member 4 and providing a channel for the second connecting member 4 to move. In some embodiments, the first connecting member 3 is generally in the shape of a sleeve, and its length direction is consistent with the length direction of the sleeve member 1. The movable cavity 304 is formed inside the first connecting member 3 and extends along the length direction of the sleeve member 1. As Figure 7 and Figure 8 shown, the second connecting member 4 is installed in the movable cavity 304 and at least part of the second connecting member 4 extends out of the movable cavity 304 from the second opening. The second connecting member 4 can move in a direction close to or away from the first connecting member 3 so that the length of the sleeve member 1 can be adjusted. One end of the second connecting member 4 away from the first connecting member 3 forms the shock absorption cavity 403. The second connecting member 4 is generally in the shape of a sleeve, and a shock absorption cavity 403 is formed inside it. At the same time, the second connecting member 4 itself is also movably installed in the movable cavity 304 and can move relatively close to or away from the first connecting member 3 along the length direction of the sleeve member 1. When the second connecting member 4 moves relatively close to the first connecting member 3, the length of the sleeve member 1 shortens. When the second connecting member 4 moves relatively away from the first connecting member 3, the length of the sleeve member 1 elongates.

[0056] Based on the relative position of the second connecting member 4 when it moves with respect to the first connecting member 3, the second connecting member 4 can have a first position and a second position. Specifically, as Figure 4 shown, when the length of the sleeve member 1 is the relatively short first length, the second connecting member 4 is in the first position; as Figure 3 shown, when the length of the sleeve member 1 is the relatively long second length, the second connecting member 4 is in the second position. In some embodiments, the sleeve member 1 further includes a locking portion and a first mating portion. Among them, the locking portion is provided on one of the first connecting member 3 and the second connecting member 4; the first mating portion is provided on the other of the first connecting member 3 and the second connecting member 4. The locking portion and the first mating portion can be structurally matched with each other. When the second connecting member 4 is in the second position, the first mating portion and the locking portion cooperate with each other to limit the second connecting member 4 from moving relative to the first connecting member 3 anymore, so that the first connecting member 3 and the second connecting member 4 can be relatively fixed, and further the length of the sleeve member 1 can be fixed at the second length. The locking portion can be provided on the first connecting member 3 or on the second connecting member 4. Correspondingly, the first mating portion can be provided on the second connecting member 4 or the first connecting member 3.

[0057] The locking part and the first mating part can be implemented in various forms. For example, the locking part can be set as a movable part that can move radially away from or close to the peripheral side wall of the second connecting member 4, and the first mating part can be set as a concave area or a hole that matches the movable part. In some embodiments, a telescopic part is elastically mounted on the second connecting member 4. Driven by the elastic force, the telescopic part can move radially away from or close to the peripheral side wall of the second connecting member 4; a hole part adapted to the end of the telescopic part is provided on the first connecting member 3; the telescopic part constitutes the locking part, and the hole part constitutes the first mating part. Among them, the telescopic part can be a rod-shaped, column-shaped, block-shaped or any other shaped part; the elastic mounting means that it can be mounted on the second connecting member 4 through an elastic member, so that the telescopic part can elastically move away from or close to the peripheral side wall of the second connecting member 4. The elastic member refers to a part that can generate an elastic force when deformed, such as a spring 6, etc. In some embodiments, the telescopic part is mounted on the second connecting member 4 through an elastic member. When the elastic member is compressed and deformed by an external force, it can drive the telescopic part to move in a direction away from the peripheral side wall of the second connecting member 4. When the elastic member is stretched and deformed by an external force, it can drive the telescopic part to move in a direction close to the peripheral side wall of the second connecting member 4. The hole part can be a blind hole or a through hole, which is formed on the inner wall of the movable cavity 304 of the first connecting member 3, and the orifice of the hole part faces inward. When the second connecting member 4 is in the second position, the telescopic part is opposite to the hole part and can extend into the hole part, thereby restricting the movement of the second connecting member 4.

[0058] Among them, multiple telescopic parts can be provided, and multiple hole parts can also be provided. The multiple telescopic parts and the multiple hole parts are in one-to-one correspondence to ensure that each telescopic part can cooperate with a hole part. The multiple telescopic parts can be distributed at any position on the second connecting member 4, as long as it is ensured that when the second connecting member 4 is in the second position, the positions of the multiple hole parts can correspond to the multiple telescopic parts one by one.

[0059] In a specific embodiment, a channel 5 is formed at one end of the second connecting member 4 close to the first connecting member 3. The channel 5 extends along the radial direction of the second connecting member 4, and both ends of the channel 5 penetrate through the circumferential side wall of the second connecting member 4 to form opposite first outlets 4011 and second outlets 4012. The telescopic part includes a first telescopic part 71 and a second telescopic part 72 movably installed in the channel 5, and a spring 6 is arranged between the first telescopic part 71 and the second telescopic part 72. The hole part includes a first through hole 3021 and a second through hole 3022 oppositely arranged on the wall of the moving cavity 304. When the second connecting member 4 is in the second position, the first through hole 3021 is opposite to the first outlet 4011, and the second through hole 3022 is opposite to the second outlet 4012. In some embodiments, the first telescopic part 71 can correspond to the first outlet 4011, and the second telescopic part 72 can correspond to the second outlet 4012. When the spring 6 deforms elastically to generate an elastic force, the first telescopic part 71 can be driven to extend out of the channel 5 from the first outlet 4011 and extend into the first through hole 3021 to cooperate with the first through hole 3021 to achieve locking. At the same time, the second telescopic part 72 can be driven to extend out of the channel 5 from the second outlet 4012 and extend into the second through hole 3022 to cooperate with the second through hole 3022 to achieve locking; the first telescopic part 71 can also be driven by the elastic force of the spring 6 to retract into the channel 5 from the first outlet 4011, so as to be received in the channel 5. Similarly, the second telescopic part 72 can also be driven by the elastic force of the spring 6 to retract into the channel 5 from the second outlet 4012, so as to be received in the channel 5.

[0060] In some embodiments, a first convex part 73 is arranged on the circumferential side wall of the first telescopic part 71. When the first telescopic part 71 extends into the first through hole 3021, the first convex part 73 cooperates with the edge of the first through hole 3021 or the edge of the first outlet 4011, so as to limit the continuous movement of the first telescopic part 71 and play a role in limiting the first telescopic part 71. The first convex part 73 can be set as an annular protrusion along the circumferential direction of the first telescopic part 71, or can be set as a plurality of protrusions arranged at intervals along the circumferential direction of the first telescopic part 71.

[0061] In some embodiments, a second convex part 74 is arranged on the circumferential side wall of the second telescopic part 72. When the second telescopic part 72 extends into the second through hole 3022, the second convex part 74 cooperates with the edge of the second through hole 3022 or the edge of the second outlet 4012, so as to limit the continuous movement of the second telescopic part 72 and play a role in limiting the second telescopic part 72. The second convex part 74 can be set as an annular protrusion along the circumferential direction of the second telescopic part 72, or can be set as a plurality of protrusions arranged at intervals along the circumferential direction of the second telescopic part 72.

[0062] In some other embodiments, a first convex portion 73 is provided on the circumferential side wall of the first telescopic portion 71, and a second convex portion 74 is provided on the circumferential side wall of the second telescopic portion 72.

[0063] During actual installation, first separate the sleeve member 1 and the rod member 2, and connect the head end of the sleeve member 1 and the second end of the rod member 2 to the box body and the barrel assembly respectively. Then push the second connecting member 4 towards the first connecting member 3 until it cannot move further. As Figure 4 shown, at this time, the top of the second connecting member 4 abuts against the closed end of the movable cavity 304. The first telescopic portion 71 and the second telescopic portion 72 are received in the channel 5 due to being restricted by the inner wall of the movable cavity 304, the spring 6 is compressed, and the length of the sleeve member 1 is shortened to the shortest length. Then align the tail end of the sleeve member 1 with the first end of the rod member 2, and pull the second connecting member 4 in the direction away from the first connecting member 3, so that the first end of the rod member 2 extends into the shock absorption cavity 403 until the first through hole 3021 is opposite to the first outlet 4011 and the second through hole 3022 is opposite to the second outlet 4012. As Figure 3 shown, at this time, the first telescopic portion 71 and the second telescopic portion 72 are no longer restricted by the inner wall of the movable cavity 304. Under the action of the spring 6, the first telescopic portion 71 moves axially out of the channel 5 and thus extends into the first through hole 3021. When the first convex portion 73 abuts against the edge of the first through hole 3021, the first telescopic portion 71 can no longer move further. At the same time, the second telescopic portion 72 moves axially out of the channel 5 and thus extends into the second through hole 3022. When the second convex portion 74 abuts against the edge of the second through hole 3022, the second telescopic portion 72 can no longer move further. The second connecting member 4 is restricted by the cooperation between the telescopic portion and the hole portion and can no longer move, thereby fixing the length of the sleeve member 1 at the current length. At this time, the sleeve member 1 and the rod member 2 are successfully assembled, and the length of the sleeve member 1 itself is fixed. When vibration occurs, the rod member 2 can move relative to the sleeve member 1, thereby achieving shock absorption.

[0064] In order to prevent the second connecting member 4 from rotating relative to the first connecting member 3 and ensure that the locking portion on the second connecting member 4 can correspond to the corresponding first mating portion on the first connecting member 3, in one embodiment, a guiding portion extending along the length direction of the first connecting member 3 is provided on the cavity wall of the movable cavity 304, and a second mating portion corresponding to the guiding portion is provided on the circumferential side wall of the second connecting member 4; when the second connecting member 4 moves in the movable cavity 304, the guiding portion cooperates with the second mating portion to restrict the second connecting member 4 from rotating relative to the first connecting member 3 and guide the second connecting member 4 to move along the length direction of the first connecting member 3.

[0065] The guiding part and the second mating part can have various implementation forms, such as the concave part and the convex part of the concave-convex fit. Specifically, the guiding part can be the groove 402, and the second mating part is the protrusion or rib 303; the guiding part can also be the protrusion or rib 303, and the second mating part is the groove 402. In an embodiment, the guiding part is arranged as a rib 303 extending along the length direction of the first connecting member 3, and the second mating part is a groove 402 extending along the length direction of the first connecting member 3. The rib 303 and the groove 402 are in concave-convex fit. When pushing the second connecting member 4, limited by the extending directions of the guiding part and the second mating part, the second connecting member 4 can only move along the extending direction of the rib 303 or the groove 402, and cannot rotate relative to the first connecting member 3.
