[0034] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] It should be noted that in the description of this utility model, terms such as "inner," "outer," "upper," "lower," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The background art points out that the connection strength between the drum shock absorber and the bottom shell of existing washing machines is not high, affecting the shock absorption effect and operational stability of the washing machine. This utility model provides a connecting device and a washing machine including the connecting device. By setting a connecting bracket between the shock absorber and the bottom shell, one end of the connecting bracket is pivotally connected to the shock absorber, and the other end is fixedly connected to the bottom shell. A limiting groove is set on the bottom shell to further restrict the relative movement between the connecting bracket and the bottom shell, thereby improving the connection strength between the shock absorber and the bottom shell and the ease of assembly.

[0038] For example, in order to more effectively absorb the vibration generated by the drum during operation, suppress the transmission of vibration to the machine body, and ensure the stability and quietness of the washing machine, a shock-absorbing device is usually installed between the drum and the machine body. That is, the drum is suspended in the machine body by means of a suspension spring or shock absorber, so as to achieve an elastic connection between the drum and the machine body.

[0039] Specifically, the top of the roller is suspended from the top of the machine body by a suspension spring, while the bottom of the roller is supported by a shock absorber. Multiple shock absorbers are provided and are installed between the roller and the bottom shell in a downward direction. The top of the shock absorber is connected to the roller, and the bottom is connected to the edge of the bottom shell.

[0040] In existing washing machines, the shock absorber is usually directly bolted to the bottom shell. Since the downward pressure of the drum is transmitted along the direction of the shock absorber downwards, it will generate vertical and horizontal components of force at the connection. As the years of use increase, the connection will loosen or even be damaged during high-intensity use, which will directly affect the stability of the shock absorber's support for the drum and its vibration absorption performance.

[0041] Based on this, such as Figures 1 to 4As shown, this utility model provides a connecting device for connecting a shock absorber and a bottom shell 4, including: a connecting bracket 1 and a limiting structure 2. The connecting bracket 1 is set as an independent component, with a fixed part 11 at its bottom, which is fixedly connected to the bottom shell 4 through the fixed part 11, and a hinge part 12 at its top, which is pivotally connected to the bottom of the shock absorber through the hinge part 12. The limiting structure 2 is set on the bottom shell 4, which can be mechanically connected to the bottom shell 4 or integrally set with the bottom shell 4. In this case, it is preferred to be integrally formed with the bottom shell 4. The limiting structure 2 can limit the fixed part 11 of the connecting bracket 1 to restrict its movement on the bottom shell 4, reduce the impact of roller vibration on the connection, and extend the service life.

[0042] For example, such as Figure 2 and Figure 4 As shown, the hinge part 12 of the connecting bracket 1 is disposed on the top of the fixed part 11. The two can be fixedly connected or integrally formed. The hinge part 12 includes a first vertical plate 121 and a second vertical plate 122 arranged at intervals. The first vertical plate 121 is provided with a first hinge hole 1211, and the second vertical plate 122 is provided with a second hinge hole 1221. The first hinge hole 1211 and the second hinge hole 1221 are arranged opposite to each other.

[0043] Correspondingly, the connecting device also includes a pin 3, which can pass through the first hinge hole 1211 and the second hinge hole 1221. The shock absorber is fixedly connected to or pivotally connected to the pin 3, realizing the pivotal connection between the shock absorber and the connecting bracket 1. The pin 3 can be set as an independent component or as part of the shock absorber. The two vertical plates set at intervals can improve the support strength, ensuring the flexibility and stability of rotation between the shock absorber and the connecting bracket 1; at the same time, it also reduces the processing difficulty and assembly difficulty of each component, making disassembly and assembly more flexible and quick.

[0044] Preferably, such as Figure 2 and Figure 4 As shown, a fixed limiting member 31 is provided at the first end of the pin 3, and an elastic limiting member 32 is provided at the second end of the pin 3.

[0045] In practical applications, the fixing and limiting member 31 can be configured as a ring structure, a frustum structure, or a protrusion structure 21, etc., wherein the diameter of the pin 3 is slightly smaller than the diameter of the first hinge hole 1211 and the second hinge hole 1221, and the diameter of the fixing and limiting member 31 is slightly larger than the diameter of the first hinge hole 1211 and the second hinge hole 1221. During assembly, the second end of the pin 3 is passed through the first hinge hole 1211 and the second hinge hole 1221 in sequence, and the fixing and limiting member 31 cannot pass through, thus limiting the pin 3 and preventing the pin 3 from continuing to move from the first hinge hole 1211 to the second hinge hole 1221 and falling off.

[0046] The elastic limiting member 32 is disposed on the outer circumferential surface of the pin 3 and can move elastically along the radial direction of the pin 3. The side near the second end is configured as an inclined structure, and the side near the first end is configured as a vertical structure. When the pin 3 passes through the hinge hole, the hinge hole will apply a squeezing force to the elastic limiting member 32 through the inclined structure to press the elastic limiting member 32 into the pin 3. When the elastic limiting member 32 has completely passed through the hinge hole, it will automatically pop out due to the disappearance of the squeezing force. At this time, the vertical structure will form a stop fit with the hinge hole to prevent the pin 3 from moving from the second hinge hole 1221 to the first hinge hole 1211 and falling off.

[0047] Through the combined action of the fixed limiting member 31 and the elastic limiting member 32, the pin 3 is axially limited in the first hinge hole 1211 and the second hinge hole 1221, preventing the pin 3 from falling off from both sides of the two hinge holes.

[0048] More preferably, such as Figure 4 As shown, the second end of the pin 3 is configured with a pointed or rounded head structure so that the pin 3 can quickly enter the hinge hole and achieve rapid assembly.

[0049] A connecting plate 123 is also provided between the first vertical plate 121 and the second vertical plate 122, connecting the first vertical plate 121 and the second vertical plate 122 into one unit. This improves the connection strength between the two, thereby enhancing the overall structural strength of the connecting bracket 1 and strengthening its support and deformation resistance.

[0050] The fixing part is located at the bottom of the connecting bracket 1 and includes a first horizontal plate 111 and a second horizontal plate 112. The first horizontal plate 111 is fixedly connected to the first vertical plate 121 or integrally formed, and the second horizontal plate 112 is fixedly connected to the second vertical plate 122 or integrally formed. The bottom of the first horizontal plate 111 and the second horizontal plate 112 are attached to the bottom shell 4 and fixedly connected.

[0051] In practical applications, the first horizontal plate 111 and the second horizontal plate 112 can be connected to the bottom shell 4 using various methods such as screwing, hinged, or riveting, as long as the connection strength between them can be ensured. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be limited to the protection scope of this utility model.

[0052] Preferably, such as Figure 4 As shown, the first horizontal plate 111 is provided with a first threaded hole 1111, and the second horizontal plate 112 is provided with a second threaded hole 1121. The first horizontal plate 111 and the second horizontal plate 112 are respectively threadedly connected to the bottom shell 4 through the first threaded hole 1111 and the second threaded hole 1121.

[0053] The first horizontal plate 111 and the second horizontal plate 112 are attached and fixed to the bottom shell 4, which increases the contact area between the connecting bracket 1 and the bottom shell 4, making the connection between the two more stable. The screw connection not only ensures the connection strength, but also facilitates disassembly and assembly.

[0054] Preferably, such as Figure 3 As shown, the limiting structure 2 is set as a limiting groove, which is surrounded by an annular baffle 22 with its opening facing upward. At the bottom of the limiting groove, there are a third threaded hole 23 and a fourth threaded hole 24 corresponding to the first threaded hole 1111 and the second threaded hole 1121. The shape and size of the limiting groove are adapted to the first horizontal plate 111 and the second horizontal plate 112, which can restrict the movement of the fixed part 11 in the horizontal direction, thereby forming a combined force with the bolt and improving the support stability of the bottom shell 4 on the connecting bracket 1 in the horizontal direction.

[0055] During assembly, the first horizontal plate 111 and the second horizontal plate 112 are first inserted into the slot so that the first threaded hole 1111 and the second threaded hole 1121 are aligned with the third threaded hole 23 and the fourth threaded hole 24 respectively. Then, bolts are inserted from the bottom of the bottom shell 4 to tighten them.

[0056] This installation method is simple and quick. Tightening the bolts from the bottom allows for sufficient operating space, is not limited by the internal structure, and improves assembly efficiency.

[0057] More preferably, a protruding structure 21 is provided on the inner wall of the limiting groove, which can restrict the movement of the fixed part 11 in the vertical direction.

[0058] The structure and principle of the protruding structure 21 are similar to those of the elastic limiting member 32. During the process of inserting the connecting bracket 1 into the limiting groove through the slot, the side walls of the first horizontal plate 111 and the second horizontal plate 112 will move downward along the inner wall of the limiting groove. During the movement, the protruding structure 21 will be squeezed, causing the protruding structure 21 to undergo elastic deformation outward. After the first horizontal plate 111 and the second horizontal plate 112 fall to the bottom of the limiting groove, the protruding structure 21 separates from the first horizontal plate 111 and the second horizontal plate 112 and rebounds inward into the limiting groove, thereby locking the first horizontal plate 111 and the second horizontal plate 112 at the bottom and preventing them from moving upward.

[0059] The combined effect of the protruding structure 21 and the bolts can improve the vertical support stability of the bottom shell 4 to the connecting bracket 1, while also ensuring the convenience of disassembly and assembly between the two.

[0060] Furthermore, the washing machine provided by this utility model, based on the aforementioned connecting device, possesses the technical effects of the aforementioned connecting device. Compared to the washing machine before the improvement, the washing machine of this utility model operates more smoothly and quietly, improves the overall structural strength, and extends its service life.

[0061] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
