Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a connecting component and a device having the connecting component. Background Art

[0002] Related art discloses an electric rice cooker, wherein the rear end of the pot lid is connected to the main body via a hinge mechanism and a damping mechanism. The pot lid can be opened / closed by rotating about the hinge shaft. During the opening process of the pot lid, the damping mechanism applies a damping force to the pot lid. The damping mechanism includes an eccentric wheel, a friction component, an elastic support component, and a damping groove. The axial hole of the eccentric wheel is fixed to the hinge shaft so that the eccentric wheel rotates with the hinge shaft. The damping groove is open at the top and its side is fixed to the rear end of the main body. The friction component is arranged at the bottom of the eccentric wheel. The friction contact surface of the friction component matches the outer circumference of the eccentric wheel, forming a sliding friction fit between the two. The lower part of the friction component is inserted into the damping groove. The support surface of the friction component is pressed against the upper end of the elastic support component. The lower end of the elastic support component is placed on the bottom surface of the damping groove.

[0003] In the above related technologies, the friction between the friction component and the eccentric wheel is easily invalidated, thereby causing damping failure. Summary of the Invention

A first matching portion is provided at the first end of the damping component. The first matching portion extends in a direction parallel to the axial direction of the first shaft hole. A plurality of second matching portions are provided at circumferential intervals on the rotating shaft. The second matching portions are suitable for being engaged with the first matching portion. An elastic member is provided between the second end of the damping component and the first connecting member.

[0006] Beneficial effect: when the second connecting member rotates relative to the first connecting member, the second connecting member drives the rotating shaft to rotate in the first shaft hole. Since the rotating shaft is provided with multiple second matching parts at intervals along the circumferential direction, the first end of the damping component is provided with a first matching part. During the rotation of the rotating shaft, the first matching part will engage with the second matching part, generating resistance to the rotation of the rotating shaft. Continuing to rotate the second connecting member will cause the first matching part on the damping component to disengage from the second matching part on the rotating shaft. Under the action of the elastic member, the first end of the damping component will remain in close contact with the rotating shaft. Continuing to rotate will cause the first matching part to engage with the second matching part again, thereby generating continuous damping force, thereby achieving a continuous and stable damping effect, and will not lose the damping effect due to surface wear after long-term use.

[0018] Beneficial effect: by providing the installation portion, the positioning and installation of the elastic member are facilitated.

[0019] In an optional embodiment, the damping component includes a damping body and a boss, the mounting portion includes the boss, and the elastic member is sleeved outside the boss and abuts against the damping body.

[0020] Beneficial effect: the elastic member is sleeved outside the convex column and abuts against the damping body, which facilitates the positioning and installation of the elastic member.

[0021] In an optional embodiment, the damping body is provided with a first limiting portion, and the first mounting groove is provided with a second limiting portion, and the second limiting portion cooperates with the first limiting portion to limit the damping component to the first mounting groove.

[0022] Beneficial effect: The second limiting portion cooperates with the first limiting portion to limit the damping component in the first installation groove, thereby preventing the damping component from escaping from the first installation groove.

[0023] In an optional embodiment, the cross-section of the damping body is in a "convex" shape, including a plate-like portion and a protruding portion, the protruding column is arranged on one side of the plate-like portion, the protruding portion is arranged on a side of the plate-like portion away from the protruding column, the first matching portion is arranged at the end of the protruding portion, and the portions of the plate-like portion located on both sides of the protruding portion constitute the first limiting portion.

[0024] Beneficial effect: The parts of the plate-like portion located on both sides of the protruding portion constitute a first limiting portion. When the plate-like portion abuts against the second limiting portion, the damping component cannot continue to move radially toward the rotating shaft, which can prevent the damping component from falling out of the first mounting groove, and can balance the force on the damping component to generate a stable damping force.

[0028] Beneficial effects: The third axial hole is symmetrically arranged with the second axial hole, and the first axial hole is located between the second axial hole and the third axial hole, so that the second connecting member can be subjected to balanced force during rotation. The setting of the fixing component can fix the rotating shaft and the second connecting member together, and the structure is more stable.

[0029] In a second aspect, the present invention further provides a device having a connection assembly, comprising: The connecting component.

[0030] Beneficial effect: In the device with a connecting component, when the second connecting member rotates relative to the first connecting member, the second connecting member drives the rotating shaft to rotate in the first shaft hole. Since the rotating shaft is provided with multiple second matching parts at intervals along the circumferential direction, the first end of the damping component is provided with a first matching part. During the rotation of the rotating shaft, the first matching part will engage with the second matching part, generating resistance to the rotation of the rotating shaft. Continuing to rotate the second connecting member will cause the first matching part on the damping component to disengage from the second matching part on the rotating shaft.

Continuing to rotate the second connecting member will cause the first matching part on the damping component to disengage from the second matching part on the rotating shaft. Under the action of the elastic member, the first end of the damping component will remain in close contact with the rotating shaft. Continued rotation will cause the first matching part to engage with the second matching part again, thereby generating a continuous damping force, preventing the lid from opening all at once, and preventing the boiling water on the lid from splashing out. Similarly, when closing the lid, the speed of the lid's rotation can be slowed down to prevent the lid from quickly falling onto the kettle body and causing loud noise.

DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0039] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Related art discloses an electric rice cooker, wherein the rear end of the pot lid is connected to the main body via a hinge mechanism and a damping mechanism. The pot lid can be opened / closed by rotating about the hinge shaft. During the opening process of the pot lid, the damping mechanism applies a damping force to the pot lid. The damping mechanism includes an eccentric wheel, a friction component, an elastic support component, and a damping groove. The axial hole of the eccentric wheel is fixed to the hinge shaft so that the eccentric wheel rotates with the hinge shaft. The damping groove is open at the top and its side is fixed to the rear end of the main body. The friction component is arranged at the bottom of the eccentric wheel. The friction contact surface of the friction component matches the outer circumference of the eccentric wheel, forming a sliding friction fit between the two. The lower part of the friction component is inserted into the damping groove. The support surface of the friction component is pressed against the upper end of the elastic support component. The lower end of the elastic support component is placed on the bottom surface of the damping groove.

[0041] In the above related technologies, the friction between the friction component and the eccentric wheel is easily invalidated, thereby causing damping failure.

[0042] In addition, the lid of the electric kettle is hinged to the kettle body. There is a finger-pressing position behind the hinge of the lid. When you need to open the lid, press it with your thumb to open it. When the pressed position contacts the kettle handle, the lid opens to its maximum position. When you need to close the lid, just buckle it back. There is a torsion spring between the lid and the kettle body. When opening the lid, the torque of the torsion spring will cause the lid to open suddenly. The speed is too fast, which can easily cause the residual hot water in the lid to splash onto the user's hands. When closing the lid, the lid is likely to fall off quickly, making a lot of noise, resulting in a poor experience in opening and closing the lid.

[0043] The following combination Figures 1 to 15 , describing embodiments of the present invention.

[0044] According to an embodiment of the present invention, on the one hand, a connection assembly is provided, including a first connection member 1 , a damping component 2 and a second connection member 4 .

[0045] Among them, the first connecting member 1 is provided with a first axial hole 101; the second connecting member 4 is hinged to the first connecting member 1 through the rotating shaft 5. When the second connecting member 4 rotates relative to the first connecting member 1, the second connecting member 4 is suitable for driving the rotating shaft 5 to rotate in the first axial hole 101; the damping component 2 is arranged between the rotating shaft 5 and the second connecting member 4, and the first end of the damping component 2 is provided with a first matching portion 201. The first matching portion 201 extends in a direction parallel to the axial direction of the first axial hole 101. The rotating shaft 5 is provided with multiple second matching portions 501 at intervals along the circumferential direction. The second matching portions 501 are suitable for being engaged with the first matching portion 201. An elastic member 3 is provided between the second end of the damping component 2 and the first connecting member 1.

[0046] In this embodiment, when the second connecting member 4 rotates relative to the first connecting member 1, the second connecting member 4 drives the rotating shaft 5 to rotate in the first shaft hole 101. Since the rotating shaft 5 is provided with multiple second matching parts 501 at intervals along the circumferential direction, the first end of the damping component 2 is provided with a first matching part 201. During the rotation of the rotating shaft 5, the first matching part 201 will engage with the second matching part 501, generating resistance to the rotation of the rotating shaft 5. Continuing to rotate the second connecting member 4 will cause the first matching part 201 on the damping component 2 to disengage from the second matching part 501 on the rotating shaft 5. Under the action of the elastic member 3, the first end of the damping component 2 will remain in close contact with the rotating shaft 5. Continuing to rotate will cause the first matching part 201 to engage with the second matching part 501 again, thereby generating a continuous damping force, thereby achieving a continuous and stable damping effect, and will not lose the damping effect due to surface wear after long-term use.

[0047] When this connecting assembly is used in an electric kettle, the first connecting member 1 serves as the handle of the kettle body, and the second connecting member 4 serves as the kettle lid. When the lid is opened, the lid drives the rotating shaft 5 to rotate within the first axial hole 101. Because the rotating shaft 5 is provided with multiple second mating portions 501 spaced circumferentially, and the damping member 2 has a first mating portion 201 at its first end, the first mating portion 201 engages with the second mating portion 501 during rotation, creating resistance to the rotation of the rotating shaft 5. Continued rotation of the second connecting member 4 disengages the first mating portion 201 on the damping member 2 from the second mating portion 501 on the rotating shaft 5. Under the force of the elastic member 3, the first end of the damping member 2 remains in close contact with the rotating shaft 5. Continued rotation causes the first mating portion 201 to reengage the second mating portion 501, generating a continuous damping force. This prevents the lid from opening suddenly, thus preventing the boiling water from splashing out of the lid. Similarly, when closing the lid, the lid's rotation is slowed, preventing it from quickly falling onto the kettle body and causing loud noise. Specifically in one embodiment, the elastic member 3 is a spring.

[0048] In one embodiment, the first connecting member 1 is provided with a first installation groove 102 , the damping component 2 is provided in the first installation groove 102 , and the first matching portion 201 is located outside the first installation groove 102 .

[0049] In this embodiment, by providing the first mounting groove 102, the positioning and installation of the damping component 2 is facilitated, and the damping component 2 does not occupy the space in the first shaft hole 101 or occupies very little space, and the structural layout is compact. The first matching portion 201 is located outside the first mounting groove 102, which can ensure that the first matching portion 201 can cooperate with the second matching portion 501 to generate a damping force during the rotation of the rotating shaft 5.

[0050] In an alternative embodiment, the first mounting groove 102 may not be provided. In this case, the damping component 2 is located in the first axial hole 101. Since the damping component 2 occupies the space inside the first axial hole 101, the outer diameter of the rotating shaft 5 needs to be smaller than the inner diameter of the first axial hole 101.

[0051] In one embodiment, the first mounting groove 102 is provided on one side of the first axial hole 101 and has a mounting opening. The mounting opening and one end of the first axial hole 101 are located on the same side of the first connecting member 1 .

[0052] In this embodiment, the first mounting groove 102 is arranged on one side of the first axial hole 101, and the structural layout is more compact. The first mounting groove 102 has a mounting opening, and the mounting opening and one end of the first axial hole 101 are located on the same side of the first connecting member 1. During installation, the damping component 2 and the elastic component 3 are assembled and axially enter the first mounting groove 102 through the mounting opening, which facilitates the installation of the damping component 2.

[0053] It should be noted that after the second connecting member 4 and the first connecting member 1 are assembled, the second connecting member 4 can cover the installation opening.

[0054] In one embodiment, the height of the first matching portion 201 outside the first installation groove 102 is h, and 0.1 mm ≤ h ≤ 1.5 mm.

[0055] In this embodiment, since the height of the first matching portion 201 outside the first installation groove 102 is 0.1 mm-1.5 mm, it will not cause a great obstacle to the installation of the rotating shaft 5, and the rotating shaft 5 can be installed smoothly.

[0056] In one embodiment, the first matching portion 201 is one of a ridge and a groove, and the second matching portion 501 is the other of the ridge and the groove.

[0057] In this embodiment, the ridges and grooves cooperate to generate a continuous damping force during the rotation of the shaft 5 . The first matching portion 201 and the second matching portion 501 have simple structures and are easy to process.

[0058] In addition, since the first matching portion 201 is one of a ridge and a groove, the damping component 2 has a simple structure and low cost.

[0059] Specifically in one embodiment, Figure 5 、 Figure 10 As shown, the first matching portion 201 is a ridge, as shown in FIG. Figure 11 As shown, the second matching portion 501 is a groove. When the second connecting member 4 rotates relative to the first connecting member 1, the second connecting member 4 drives the rotating shaft 5 to rotate in the first shaft hole 101. Since the rotating shaft 5 is provided with multiple grooves at intervals along the circumferential direction, the first end of the damping component 2 is provided with a ridge. During the rotation of the rotating shaft 5, the ridge will engage with the groove, generating resistance to the rotation of the rotating shaft 5. Continuing to rotate the second connecting member 4 will cause the ridge on the damping component 2 to disengage from the groove on the rotating shaft 5. Under the action of the elastic member 3, the first end of the damping component 2 will remain in close contact with the rotating shaft 5. Continuing to rotate will cause the ridge to engage with the groove again, thereby generating a continuous damping force, thereby achieving a continuous and stable damping effect, and will not lose the damping effect due to surface wear after long-term use.

[0060] In one embodiment, the cross-sectional profiles of the ridges and grooves are arc-shaped.

[0061] In this embodiment, since the cross-sectional profiles of the ridges and the grooves are arc-shaped, the ridges can be smoothly inserted into and removed from the grooves, and the wear on the ridges and the grooves during use can be reduced.

[0062] In one embodiment, a plurality of first matching portions 201 are provided, and the distribution of the plurality of first matching portions 201 matches the distribution of the second matching portions 501 .

[0063] In this embodiment, since there are multiple first matching portions 201 , multiple first matching portions 201 and second matching portions 501 will be engaged with each other at the same time, which can make the rotation process of the rotating shaft 5 more stable.

[0064] Specifically in one embodiment, the first matching portion 201 is a ridge, the number of which is 1-20, the second matching portion 501 is a groove, the number of which is 6-100, and the circumferential angle between two adjacent grooves is equal to the circumferential angle between two adjacent ridges.

[0065] In one embodiment, the damping component 2 is provided with a mounting portion, and the elastic member 3 is mounted on the mounting portion and abuts against the bottom of the first mounting groove 102 .

[0066] In this embodiment, the installation portion is provided to facilitate the positioning and installation of the elastic member 3 .

[0067] In one embodiment, Figure 5 and Figure 10 As shown, the damping component 2 includes a damping body 202 and a boss 203 , the mounting portion includes the boss 203 , and the elastic member 3 is sleeved outside the boss 203 and abuts against the damping body 202 .

[0068] In this embodiment, the elastic member 3 is sleeved outside the protruding column 203 and abuts against the damping body 202 , so as to facilitate the positioning and installation of the elastic member 3 .

[0069] In an alternative embodiment, the mounting portion may be a blind hole, and one end of the elastic member 3 is located in the blind hole.

[0070] In one embodiment, the damping body 202 is provided with a first limiting portion 20211 , and the first installation slot 102 is provided with a second limiting portion 1023 . The second limiting portion 1023 cooperates with the first limiting portion 20211 to limit the damping component 2 in the first installation slot 102 .

[0071] In this embodiment, the second limiting portion 1023 cooperates with the first limiting portion 20211 to limit the damping component 2 in the first installation groove 102 , thereby preventing the damping component 2 from escaping from the first installation groove 102 .

[0072] In one embodiment, the cross-section of the damping body 202 is in the shape of a "convex" character, including a plate-like portion 2021 and a protruding portion 2022. The protruding column 203 is arranged on one side of the plate-like portion 2021, and the protruding portion 2022 is arranged on the side of the plate-like portion 2021 away from the protruding column 203. The first matching portion 201 is arranged at the end of the protruding portion 2022, and the parts of the plate-like portion 2021 located on both sides of the protruding portion 2022 constitute a first limiting portion 20211.

[0073] In this embodiment, the parts of the plate-like portion 2021 located on both sides of the protruding portion 2022 constitute a first limiting portion 20211. When the plate-like portion 2021 abuts against the second limiting portion 1023, the damping component 2 cannot continue to move radially toward the rotating shaft 5, which can prevent the damping component 2 from escaping from the first mounting groove 102, and can balance the force on the damping component 2 to generate a smooth damping force.

[0074] In one embodiment, Figure 9 As shown, the first mounting groove 102 includes a first groove section 1021 and a second groove section 1022. The width of the first groove section 1021 is greater than the width of the second groove section 1022. A first step surface is formed between the first groove section 1021 and the second groove section 1022. The first step surface constitutes a second limiting portion 1023. The plate-like portion 2021 and the boss 203 are arranged in the first groove section 1021, and at least part of the protrusion 2022 is arranged in the second groove section 1022.

[0075] In this embodiment, the first step surface constitutes the second limiting portion 1023, the plate-like portion 2021 and the boss 203 are arranged in the first groove section 1021. When the plate-like portion 2021 abuts against the first step surface, the damping component 2 can be prevented from falling out of the first mounting groove 102. At least part of the protrusion 2022 is arranged in the second groove section 1022.

[0104] According to an embodiment of the present invention, on the other hand, a device having a connection component is provided, which includes the connection component provided in the above embodiment.

[0105] The device with a connecting component, when the second connecting member 4 rotates relative to the first connecting member 1, the second connecting member 4 drives the rotating shaft 5 to rotate in the first shaft hole 101. Since the rotating shaft 5 is provided with multiple second matching parts 501 at intervals along the circumferential direction, the first end of the damping component 2 is provided with a first matching part 201. During the rotation of the rotating shaft 5, the first matching part 201 will engage with the second matching part 501, generating resistance to the rotation of the rotating shaft 5. Continuing to rotate the second connecting member 4 will cause the first matching part 201 on the damping component 2 to disengage from the second matching part 501 on the rotating shaft 5. Under the action of the elastic member 3, the first end of the damping component 2 will remain in close contact with the rotating shaft 5. Continuing to rotate will cause the first matching part 201 to engage with the second matching part 501 again, thereby generating a continuous damping force, thereby achieving a continuous and stable damping effect, and will not lose the damping effect due to surface wear after long-term use.

[0106] In one embodiment, the device having the connecting assembly is an electric kettle, the first connecting member 1 is a handle of the kettle body, and the second connecting member 4 is a kettle lid.

[0107] When the electric kettle is opened, the lid drives the rotating shaft 5 to rotate in the first axial hole 101. Since the rotating shaft 5 is provided with a plurality of second matching portions 501 spaced circumferentially, and the first end of the damping component 2 is provided with a first matching portion 201, during the rotation of the rotating shaft 5, the first matching portion 201 engages with the second matching portion 501, generating resistance to the rotation of the rotating shaft 5. Continuing to rotate the second connecting member 4 causes the first matching portion 201 on the damping component 2 to disengage from the second matching portion 501 on the rotating shaft 5. Under the action of the elastic member 3, the first end of the damping component 2 remains in close contact with the rotating shaft 5. Continuing to rotate causes the first matching portion 201 to engage with the second matching portion 501 again, thereby generating a continuous damping force. This prevents the lid from opening suddenly, thus preventing the boiling water on the lid from splashing out. Similarly, when closing the lid, the rotation speed of the lid can be slowed down to prevent the lid from quickly falling onto the kettle body and causing a loud noise.

[0108] Specifically in one embodiment, Figure 12 As shown, the pot lid includes a lid body 405 and a mounting structure 406 arranged on one side of the lid body 405. The mounting structure 406 is provided with a second axial hole 401 and a third axial hole 403. The top of the mounting structure 406 constitutes a lid opening button position 4061. When the lid needs to be opened, the lid can be opened by pressing the lid opening button position 4061 with a finger.

[0109] It should be noted that the device with the connection assembly may also be a water cup, an electric rice cooker, or other products.

[0110] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
