Description

Technical Field

[0001] The present invention belongs to the field of electrical appliances, and more particularly, to a connection mechanism and a laundry treatment device. Background Art

[0002] In the prior art, the door body and the main body of a laundry treatment device are connected by a hinge to realize the opening and closing of the door body. Due to the development of technology and the diversification of the functions of laundry treatment devices, it is often necessary to provide electric control devices and components on the door body, such as a lighting device on the door body. This requires an electrical connection between the main body and the door body, and the power supply device of the main body is connected to the door body. However, the door body and the main body are movably connected, and wiring at the connection between the two often faces problems such as cable loosening and cable damage, and this situation becomes more serious as the number of times the door body opens and closes increases. Especially in a drum washing machine, since the door body of the drum washing machine is small in size and the space between it and the main body is limited, arranging wiring in this limited space increases the risk of cable breakage and damage during the opening and closing of the door body on the one hand; on the other hand, arranging wiring at the limited connection position between the door body and the main body also affects the smoothness of the door body opening and closing and the usability of the door body. Further, especially in the application of a drum washing machine, in order to facilitate users to pick up and place items, the opening and closing angle of the door body is often large, increasing the travel of the door body during use, and thus increasing the risk of cable damage caused by the opening and closing of the door body. Moreover, the range of the opening and closing angle of the door body is selected according to the needs of users during use. For the situation where the opening and closing degree of the door body is uncertain, it is required that no matter what the angle and degree of the opening and closing of the door body are, good cable guiding and protecting effects should be achieved. Therefore, how to realize wiring at the connection position between the door body and the main body; how to fully realize the protection and guiding effects on the cable during the wiring process; how to make the wiring method and the auxiliary wiring structure adapt to any opening and closing angle and degree of the door body and ensure that no matter how the door body opens and closes, it will not affect the cable; how to realize wiring and cable protection without affecting the opening and closing action of the door body, and increase the structural complexity of the connection structure between the door body and the main body, and avoid occupying too much space, have become problems to be solved urgently.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0034] Preferably, a bushing is provided between the connecting guide and the second hinge.

[0035] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

[0036] 1. Through the connection mechanism introduced in the present invention, an independent auxiliary device is established between the main body and the door body to assist the transition of the cable between the main body and the door body, and to ensure the protection, guidance, and positioning of the cable during the transition process, so that during the use of the device, the cable will not be damaged or fatigued due to the relative movement, flipping, opening, and closing between the door body and the main body; moreover, it is ensured that the setting of the auxiliary device will not affect the structure of the device, avoid occupying too much space, and avoid causing obstacles to the connection and movement between the door body and the main body.

[0037] 2. Through the connection mechanism introduced in the present invention, it can largely meet the transition of the cable between relatively movable components. The auxiliary device introduced in the present invention guides the cable in different stages according to the extension direction of the cable, so that the cable is basically kept smooth and stable in each direction, without obvious local bending phenomenon, ensuring that during the use of the device, the opening and closing of the door body will not cause a large degree of bending of the local cable, avoiding cable damage and fatigue damage.

[0038] 3. Through the connection mechanism introduced in the present invention, the auxiliary device is a relatively independent mechanism, which can be freely separated and installed from the device, and the auxiliary device will not increase the burden on the device, increasing the flexibility of use of the auxiliary device. Moreover, this design extends the extension distance of the cable inside the auxiliary device to a certain extent, so that when necessary elastic deformation occurs at this place, the cable can share the deformation amount everywhere, avoiding the concentration of stress and deformation amount, and making the transition of the cable between the door body and the main body more gentle.

[0039] 4. Through the connecting mechanism introduced in the present invention, a connecting mechanism is provided between the door body and the main body, enabling the main body and the door body to be movably connected through the connecting mechanism. Further, a cooperation relationship is established between the auxiliary device and the connecting mechanism in the present invention, so that the auxiliary device is indirectly connected to the main body and / or the door body. When relative movement occurs between the main body and the door body, the connecting mechanism drives at least a part of the auxiliary device and the cable inside it to move. Since the main body and the door body are combined through the connecting mechanism, the position of the connecting mechanism is the most stable part of the combination between the two, making the guiding and leading effects of the auxiliary device on the cable more stable. Further, at least a part of the auxiliary device is arranged on the connecting mechanism in this design, avoiding overly complex component cooperation relationships of the device and excessive occupation of the device space by the auxiliary device. Preferably, the connecting mechanism is a hinge structure.

[0040] 5. Through the connecting mechanism introduced in the present invention, a limiting part is arranged on the connecting mechanism to control the relative movement range between the various parts of the connecting mechanism, avoiding possible damage-causing deformation due to excessive opening and closing that may cause excessive movement of the connecting mechanism and the auxiliary device arranged thereon. Protect the cable by controlling the opening and closing range of the connecting mechanism. Preferably, one side of the limiting part can abut against the second hinge, and the other side always abuts against the auxiliary device (the second auxiliary device), enhancing the connection stability of the auxiliary device and avoiding contact between the limiting part and the guiding part, and protecting the guiding part through the auxiliary device.

[0041] 6. Through the connecting mechanism introduced in the present invention, the interior of the auxiliary device is set to a cavity / groove structure, wrapping the cable to a large extent and enhancing the protection effect on the cable.

[0042] 7. Through the connecting mechanism introduced in the present invention, the structure of the first auxiliary device is designed to enhance the cooperation between the auxiliary device and the connecting mechanism. And the size of one end of the first auxiliary device is larger than that of the other end, so that there is a change in the dimension in the extending direction. In this direction, the non-uniformity of the structure can play a limiting role to prevent sliding between the assembling part and the fixing part. Moreover, the larger-sized part provides space for the bending deformation of the cable, avoiding damage to the cable caused by stretching and impact.

[0043] 8. Through the connecting mechanism introduced in the present invention, the size of the end of the first auxiliary device far from the second auxiliary device is larger than that of the other end, that is, the size of the first auxiliary device is increased in the part with a more spacious space, which is convenient for installation and for adding other components here.

[0044] 9. By means of the connecting mechanism introduced in the present invention, a guiding mechanism is added, and the guiding mechanism is a discontinuous structure. Each guiding mechanism guides and positions the cable in different ways, avoiding the overly tight combination between the auxiliary device and the cable, which may affect the necessary elastic deformation of the cable and allowing the cable to deform and move reasonably in the auxiliary device.

[0045] 10. By means of the connecting mechanism introduced in the present invention, a connection relationship is established between the second auxiliary device and the connection guide. In the structure of the connecting mechanism, the connection guide is used to fix the connection of the first hinge and the second hinge perpendicular to the opening and closing direction, so that there is no relative displacement between the two in this direction. That is to say, the connection guide is a mechanism with a relatively stable structure and position. Establishing a connection relationship between the connection guide and the auxiliary device can maintain good connection stability. Moreover, when the connection guide has to undergo a certain amount of elastic deformation, it will also drive the auxiliary device and the cable inside it to undergo corresponding deformations, avoiding unnecessary forces on the auxiliary device and the cable inside it, and thus avoiding damage.

[0046] 11. By means of the connecting mechanism introduced in the present invention, a connection relationship is established among the fitting, the auxiliary device, and the door body / body. On the one hand, the number of required connecting components is reduced, the installation positions of the connecting components are decreased, the structure is simplified, and at the same time, a connection relationship is established among the three, increasing the integrity among the components. When elastic deformation occurs, the three deform together, which helps to reduce the amount of deformation and also avoid stress concentration.

[0066] Embodiment 1

[0067] As Figures 1 to 7 shown, in the connection mechanism of this embodiment, an auxiliary device for guiding and protecting the cable is provided on the connection mechanism, so that the cable extends between the relatively movable components connected to the connection mechanism. At least a part of the auxiliary device is arranged on the connection mechanism. The auxiliary device includes a first auxiliary device 31 and a second auxiliary device 32 for guiding the cable in two directions. Through the connection mechanism introduced in the present invention, the body and the door body are movably connected through the connection mechanism. Further, a cooperation relationship is established between the auxiliary device and the connection mechanism in the present invention, so the auxiliary device is indirectly connected to the body and / or the door body. When the body and the door body move relative to each other, the connection mechanism drives the auxiliary device (at least a part of it) and the cable inside it to move. Since the body and the door body are combined through the connection mechanism, the position of the connection mechanism is the most stable part of the combination between the two, making the guiding and leading effect of the auxiliary device on the cable more stable. Further, this design arranges at least a part of the auxiliary device on the connection mechanism, avoiding making the component cooperation relationship of the device too complex and avoiding the auxiliary device occupying too much space of the device. Preferably, the connection mechanism is a hinge structure.

[0068] Furthermore, the extending directions of the first auxiliary device 31 and the second auxiliary device 32 in this embodiment form a certain angle, and the range of the angle is 45° to 175°; preferably, the angle is 90°. The auxiliary device is a relatively independent mechanism and can be freely separated from and installed on the device. Moreover, the auxiliary device does not increase the burden on the device, increasing the flexibility of use of the auxiliary device. And to a certain extent, this design extends the extending distance of the cable inside the auxiliary device, so that when necessary elastic deformation occurs at this place, each part of the cable can share the deformation amount, avoiding the concentration of stress and deformation amount, and making the transition of the cable between the door body and the main body more gentle.

[0069] Embodiment 2

[0070] As Figure 3 、 Figure 5 shown, the difference between the connection mechanism in this embodiment and the above embodiment is that: the connection mechanism includes a first hinge 51 and a second hinge 52, and the first hinge 51 and the second hinge are connected in a turnable manner; the connection mechanism 5 includes a limiting part 4 for controlling the relative displacement degree between the first hinge 51 and the second hinge 52. The limiting part 4 is at least arranged on the first hinge 51, so that the opening and closing range between the first hinge 51 and the second hinge 52 is between 0° and 160°; preferably, the opening and closing range between the first hinge 51 and the second hinge 52 is between 0° and 125°. When the opening and closing angle between the first hinge and the second hinge reaches the upper limit of this range, the limiting part blocks its further movement.

[0071] Through the connection mechanism introduced in this embodiment, a limiting part is arranged on the connection mechanism to control the relative movement range between the various parts of the connection mechanism, avoiding possible damaging deformations caused by excessive opening and closing of the connection mechanism and the auxiliary device arranged thereon. Protect the cable from the aspect of controlling the opening and closing range of the connection mechanism. Preferably, one side of the limiting part can abut against the second hinge, and the other side always abuts against the auxiliary device (the second auxiliary device), enhancing the connection stability of the auxiliary device and being able to avoid the contact between the limiting part and the guiding part, and protecting the guiding part through the auxiliary device.

[0072] Embodiment 3

[0073] As Figures 6 to 11 shown, the difference between the connection mechanism in this embodiment and the above embodiment is that: the inside of the auxiliary device is a cavity / groove structure capable of accommodating the cable. By setting the inside of the auxiliary device as a cavity / groove structure, the cable is wrapped to a large extent, enhancing the protection effect on the cable.

[0074] Furthermore, the first auxiliary device 31 in this embodiment includes a mating connection assembly portion 311 and a fixing portion, and a cavity capable of accommodating a cable is formed therebetween. The fixing portion is a groove formed by the first auxiliary device 31 recessing towards one side, and the assembly portion 311 can be embedded / carded into the groove. One end of the first auxiliary device 31 has a larger size than the other end, so that the size of the cavity inside it is different in the extending direction. Preferably, the size of the end of the first auxiliary device 31 away from the second auxiliary device 32 is larger than that of the other end. Through the connection mechanism introduced in the present invention, the structure of the first auxiliary device is designed to enhance the cooperation between the auxiliary device and the connection mechanism. And the fact that one end of the first auxiliary device has a larger size than the other end results in a change in the scale in the extending direction, and in this direction, the non-uniformity of the structure can play a role in limiting the position, preventing the sliding between the assembly portion and the fixing portion. Moreover, the larger-sized part provides space for the bending deformation of the cable, avoiding damage to the cable caused by stretching and impact effects.

[0075] Even more preferably, the first auxiliary device 31 is connected to the first hinge 51 / second hinge 52 at the end away from the second auxiliary device 32 through a connecting member 313; the connecting member 313 passes through the cavity formed between the assembly portion 311 and the fixing portion. The size of the end of the first auxiliary device 31 away from the second auxiliary device 32 is larger than that of the other end, that is, the size of the first auxiliary device is increased in the part with a more spacious space, which is convenient for installation and also convenient for adding other components here.

[0076] Embodiment 4

[0077] As Figures 6 to 11 shown, the difference between the connection mechanism in this embodiment and the above embodiments is that: the auxiliary device includes a guiding mechanism for guiding the cable path and fixing the cable position, the guiding mechanism is arranged on the first auxiliary device 31, and the guiding mechanism includes a first guiding mechanism 331 formed by the first auxiliary device 31 protruding towards one side. The first guiding mechanism 331 and the first auxiliary device 31 together form an annular structure allowing the cable to pass through;

[0078] Furthermore, the guiding mechanism in this embodiment includes a second guiding mechanism 332 formed by a groove-shaped structure / a notch-shaped structure allowing the cable to pass through, which is formed by the depression / vacancy at the edge of the fixing portion and / or the assembly portion 311.

[0079] Furthermore, the guiding mechanism in this embodiment includes a third guiding mechanism 333 arranged on the side of the fixing portion and / or the assembly portion 311 facing the cavity, and the third guiding mechanism is a convex structure.

[0080] Through the connection mechanism introduced in this embodiment, a guiding mechanism is added, and the guiding mechanism is a discontinuous structure. Each guiding mechanism guides and positions the cable in different ways, avoiding the cable being too tightly combined with the auxiliary device and affecting the necessary elastic deformation of the cable, and allowing the cable to deform and move reasonably in the auxiliary device.

[0081] Further, the second auxiliary device 32 in this embodiment includes a guiding portion 321 and a mounting portion 322; the second auxiliary device 32 is connected to the body / door / connection mechanism through the mounting portion 322, and a cavity / groove allowing the cable to pass through is formed inside the guiding portion. The inside of the guiding portion communicates with the cavity of the first auxiliary device 31 to jointly form a passage allowing the cable to pass through;

[0082] Further, the guiding portion 321 in this embodiment is connected to the connection mechanism through a connection hole provided thereon and a connecting portion 324 passing through the connection hole.

[0083] Through the connection mechanism introduced in this embodiment, a connection relationship is established between the second auxiliary device and the connection guiding member. In the structure of the connection mechanism, the connection guiding member is used to fix the connection between the first hinge and the second hinge perpendicular to the opening and closing direction, so that the two will not have relative displacement in this direction, that is to say, the connection guiding member is a mechanism with relatively stable structure and position. Establishing a connection relationship between the connection guiding member and the auxiliary device can maintain good connection stability. And when the connection guiding member has to undergo a certain amount of elastic deformation, it will also drive the auxiliary device and the cable inside it to undergo corresponding deformation, avoiding unnecessary stress on the auxiliary device and the cable inside it, and thus avoiding damage.

[0084] Further, the connection mechanism in this embodiment includes a connection guiding member 7 for guiding the rotation direction between the first hinge 51 and the second hinge 52;

[0085] Preferably, the mounting portion 322 is connected to the connection guiding member 7;

[0086] More preferably, the mounting portion 322 is a slot structure, and the connection guiding member 7 is connected and embedded in the slot;

[0087] Even more preferably, an avoidance portion 323 is provided on the mounting portion 322, and the avoidance portion 323 corresponds to the connecting portion 324.

[0088] Through the connection mechanism introduced in this embodiment, a connection relationship is established among the fitting, the auxiliary device and the connection guiding member. On the one hand, the number of required connection components is reduced, the installation positions of the connection components are reduced, the structure is simplified, and at the same time, a connection relationship is established among the three, increasing the integrity among the components, so that the three deform together when elastic deformation occurs, which helps to reduce the amount of deformation and avoid stress concentration.

[0089] Example 5

[0090] As Figures 1 to 4 , Figure 7 shown, the difference between the connection mechanism of this embodiment and the above embodiment is that: the second hinge 52 is connected to the door body through a fitting. The fitting includes a first fitting 81 for limit connection; the number of the first fittings 81 is at least two. At least one of the first fittings 81 passes through the cavity of the first auxiliary device 31, and at least one of the first fittings 81 is a structure protruding toward the door body side. The fitting includes a second fitting 82 for positioning; the number of the second fittings 82 is at least two. Preferably, at least one of the second fittings 82 is a hook-shaped structure extending in the extending direction of the door body.

[0091] Through the connection mechanism introduced in this embodiment, a connection relationship is established among the fitting, the auxiliary device and the connection guide. On the one hand, the number of required connection components is reduced, the installation positions of the connection components are reduced, the structure is simplified, and at the same time, a connection relationship is established among the three, the integrity among the components is increased, so that when elastic deformation occurs, the three deform together, which helps to reduce the amount of deformation that occurs and can also avoid stress concentration.

[0092] Furthermore, a bushing is provided between the connection guide introduced in this embodiment and the second hinge, so that the connection gap between the two is smaller and protection is provided.

The body includes a feeding port corresponding to the door body, and the first hinge is connected thereto at the rear side of the feeding port.

[0095] Preferably, the first hinge is an arc-shaped structure having the same contour and size as the feeding port, so that the connection between the first hinge and the feeding port is a surface connection. The first hinge and the feeding port are connected by matching screws and screw holes. A bushing is provided between the connection guide and the second hinge. Through the laundry treatment device introduced in this embodiment, a more stable connection can be established between the body and the door body. Since the connection between the connection mechanism and the arc-shaped component, such as the feeding port, is a surface contact, the compatibility, integrity and connection stability between the two are ensured.
