[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 creative work are within the scope of protection of the present invention.

[0072] Combine the following Figures 1 to 14 , describing an embodiment of the present invention.

[0073] According to an embodiment of the present invention, on the one hand, a connection assembly is provided, including a first connection member 1 , a second connection member 2 , a damper 3 and a first joint 4 .

[0074] The first connecting member 1 has a first hinge hole 101. The second connecting member 2 has a second hinge hole 201. The damper 3 includes a damper housing 301 and a damper inner core 302. The damper housing 301 can move relative to the damper inner core 302 and generate a damping force. The damper inner core 302 is limited in the first hinge hole 101. The first joint 4 is limited in the second hinge hole 201. The first joint 4 is provided with one of a limiting groove 401 and a limiting rib 3011, and the damper housing 301 is provided with the other of the limiting groove 401 and the limiting rib 3011. The limiting rib 3011 is provided in the limiting groove 401.

[0075] During use of the connecting assembly of the embodiment of the present invention, when the second connecting member 2 rotates relative to the first connecting member 1, the first joint 4 is also rotated with it. The first joint 4 drives the damper housing 301 to rotate synchronously through the cooperation between the limiting rib 3011 and the limiting groove 401. The damper core 302 is limited in the first hinge hole 101, so that the damper housing 301 and the damper core 302 can move relative to each other. A damping force can be generated between the damper housing 301 and the damper core 302, which can slow down the rotation speed of the second connecting member 2, thereby preventing the second connecting member 2 from rotating at a faster speed and colliding with the first connecting member 1, causing loud noise and damage to the first connecting member 1 or the second connecting member 2, thereby helping to improve user experience.

[0076] Furthermore, since the damper core 302 is limited in the first hinge hole 101, the damper core 302 can directly cooperate with the hole wall of the first hinge hole 101 for limiting, and there is no need to separately set a joint to limit the end of the damper core 302. This saves a joint, can reduce the number of parts of the connecting assembly, makes the structure of the connecting assembly simpler and more compact, and helps to reduce the manufacturing cost of the connecting assembly.

[0077] In the embodiment of the present application, the damper inner core 302 is limited to the first hinge hole 101, which means that the damper inner core and the first hinge hole are relatively static. The first joint 4 is limited to the second hinge hole 201, which means that the first joint and the second hinge hole are relatively static, and rotate synchronously with the second connecting member 2 when the second connecting member 2 rotates.

[0078] In one embodiment, a plurality of damping chambers are formed between the damper core 302 and the damper shell 301, and damping medium is provided in the damping chamber. When the damper shell 301 rotates relative to the damper core 302 under the action of the second connecting member 2, the damping medium in one damping chamber can flow to the adjacent damping chamber through the gap between the second rib and the damper core 302, thereby generating a damping force.

[0079] The damping medium is preferably but not limited to damping oil.

[0080] In one embodiment, two second ribs are provided on the inner wall of the damper housing 301, and two third ribs are provided on the outer side of the damper core 302. The second ribs are clearance-matched with the damper core 302, and the third ribs are in contact with the inner wall of the damper housing 301. The space between the second ribs and the third ribs forms the damping cavity.

[0081] As a convertible embodiment, a friction surface is formed between the damper inner core 302 and the damper outer shell 301. The friction surface has a large damping coefficient, so that a damping force can be generated after the damper outer shell 301 rotates relative to the damper inner core 302.

[0082] In one embodiment, Figure 5 As shown, the first connector 4 is provided with one of a first plug block 402 and a first slot 2013 .

[0083] like Fig.12 As shown, the other of the first inserting block 402 and the first slot 2013 is provided on the inner circumference of the second hinge hole 201 , and the first inserting block 402 is provided in the first slot 2013 .

[0084] The first plug block 402 can be plugged into the first slot 2013 , so that when the second connecting member 2 rotates along the first direction, the first connector 4 can be driven to rotate along the first direction through the first slot 2013 .

[0085] On this basis, in the embodiment of the present application, the first connector 4 is limitedly cooperated with the second connector 2 through the first plug block 402, so that the entire first connector 4 can be set into a ring shape, thereby facilitating the processing of the first connector 4, and making the size of the first connector 4 stable and reliable, thereby improving the assembly efficiency of the first connector 4.

[0086] As a convertible embodiment, in an embodiment not shown in the accompanying drawings, the second hinge hole 201 is a special-shaped hole, and the shape of the first joint 4 is configured to be compatible with the second hinge hole 201, so that when the second connecting member 2 rotates relative to the first connecting member 1, the first joint 4 can rotate synchronously with the first connecting member 1.

[0087] In one embodiment, the size of the first slot 2013 along the circumference of the second hinge hole 201 can be optionally configured to be compatible with the first plug block 402, so that the first joint 4 can be driven to rotate synchronously when the second connecting member 2 rotates.

[0088] As a convertible implementation, in an embodiment not shown in the drawings, the size of the first slot 2013 along the circumference of the second hinge hole 201 is larger than the size of the first plug block 402 .

[0089] By such arrangement, when the second connecting member 2 rotates in the first direction relative to the first connecting member 1, at the beginning, the first plug block 402 may not abut against the groove wall of the first slot 2013, and the first plug block 402 may rotate in the first slot 2013, and the second connecting member 2 may rotate quickly relative to the first connecting member 1.

[0090] When the first inserting block 402 abuts against the groove wall of the first inserting slot 2013 , the second connecting member 2 carries the damper housing 301 to rotate synchronously, and causes the damper housing 301 and the damper inner core 302 to move relative to each other.

[0091] A damping force can be generated between the damper housing 301 and the damper core 302, thereby slowing down the rotation speed of the second connecting member 2 and preventing the second connecting member 2 from quickly colliding with the first connecting member 1 to generate noise or cause damage to the first connecting member 1 or the second connecting member 2.

[0092] In one embodiment, Figure 5 As shown, a first plug block 402 is provided on the first joint 4 , a limiting groove 401 is provided on the first plug block 402 , and a limiting rib 3011 is correspondingly provided on the damper housing 301 .

[0093] By such arrangement, the first plug block 402 can be used to limit the first joint 4 in the second hinge hole 201, and can also be used to limit the first joint 4 and the damper housing 301. The first plug block 402 has multiple functions and can make the structure of the first joint 4 simpler and more compact.

[0094] As a convertible implementation, in an embodiment not shown in the drawings, a first slot 2013 is provided on the first joint 4, a limiting protrusion is provided in the first slot 2013, and a limiting groove 401 for accommodating the limiting protrusion is correspondingly provided on the damper housing 301.

[0095] In one embodiment, a first annular boss 102 is provided on the inner periphery of the first hinge hole 101 (see Figure 7 ), the damper inner core 302 is provided with a second plug block 3021 and a second slot 1021 (see Figure 4 ) One of the two, the first annular boss 102 is provided with the other of the second plug block 3021 and the second slot 1021.

[0096] The second slot 1021 can be plugged into the second plug block 3021, so that the damper core 302 is limited in the first hinge hole 101, ensuring that when the second connecting member 2 rotates, the damper core 302 can move relative to the damper shell 301, thereby generating a damping force.

[0097] In one embodiment, Figure 7 As shown, a first avoidance groove 1022 is provided on the first annular boss 102. The first avoidance groove 1022 extends along the circumferential direction of the first annular boss 102. The first plug block 402 is disposed in the first insertion slot 2013 and can rotate in the first avoidance groove 1022.

[0098] By such arrangement, the first annular boss 102 can limit the damper core 302 to ensure that the damper core 302 and the first connecting member 1 are relatively stationary, and will not hinder the first joint 4 from rotating relative to the first annular boss 102 driven by the second connecting member 2.

[0099] In addition, the connecting assembly of the embodiment of the present application limits the damper inner core 302 through the first annular boss 102, and there is no need to add a joint in the first hinge hole 101 to cooperate with the damper inner core 302. This saves a joint, can reduce the number of parts of the connecting assembly, makes the structure of the connecting assembly simpler and more compact, and helps to reduce the manufacturing cost of the connecting assembly.

[0100] In one embodiment, the angle of the first avoidance groove 1022 can be set according to the maximum rotation angle of the first connecting member 1 and the second connecting member 2 .

[0101] Exemplarily, when the connecting component is a connecting component of an electric kettle, the angle of the first avoidance groove 1022 needs to be able to ensure that the kettle cover does not fall automatically when the kettle is placed normally, and generally needs to be greater than 90°.

[0102] In one embodiment, Fig. 9 As shown, a second avoidance groove 1023 is provided on the first annular boss 102. The second avoidance groove 1023 is provided in the first avoidance groove 1022 and extends along the circumferential direction of the first annular boss 102. The limiting rib 3011 is provided in the second avoidance groove 1023 and can rotate in the second avoidance groove 1023.

[0103] By such arrangement, the first annular boss 102 can limit the damper inner core 302 to ensure that the damper inner core 302 and the first connecting member 1 are relatively stationary, and will not hinder the damper outer shell 301 from rotating relative to the first annular boss 102 driven by the first joint 4.

[0104] As a convertible implementation mode, in an embodiment not shown in the accompanying drawings, the second avoidance groove 1023 may be optionally not provided in the first avoidance groove 1022, and the limiting rib 3011 of the damper housing 301 can rotate in the first avoidance groove 1022 synchronously with the first plug block 402.

[0105] In one embodiment, Figure 2 and Figure 3 As shown, the second hinge holes 201 are arranged in pairs and are arranged on both sides of the first hinge hole 101 . The first joint 4 passes through one of the second hinge holes 201 and is plugged into the damper housing 301 .

[0106] By setting two second hinge holes 201 and making the first hinge hole 101 between the two second hinge holes 201, the first joint 4 is connected to a second hinge hole 201 and plugged into the damper housing 301, so that the second connecting member 2 can be stably stressed and is not prone to shaking during rotation.

[0107] Exemplarily, in one embodiment, a connecting protrusion is provided on the second connecting member 2, a connecting groove is provided in the middle of the connecting protrusion, second hinge holes 201 are respectively provided on the groove walls on opposite sides of the connecting groove, and the first hinge hole 101 of the first connecting member 1 can be arranged in the connecting groove, and both ends are connected to the first second hinge hole 201.

[0108] As a convertible implementation, in an embodiment not shown in the drawings, the number of the second hinge hole 201 is one and is disposed at one side of the first hinge hole 101 .

[0109] In one embodiment, Figure 3 As shown, the connection assembly further includes a second joint 6. The second joint 6 and the first joint 4 are respectively arranged at both ends of the damper 3, and the second joint 6 is arranged in the second hinge hole 201. The hinge shaft 5 passes through the first joint 4, the damper inner core 302 and the second joint 6 in sequence.

[0110] The hinge shaft 5 is used to connect the first joint 4, the damper 3 and the second joint 6 together, and to hinge the first connecting member 1 and the second connecting member 2 to each other.

[0111] By such arrangement, the first joint 4 can not only be used to promote synchronous movement of the damper housing 301 and the second connecting member 2, but also can be used to cooperate with the second joint 6 to limit the damper 3 on the first connecting member 1 to prevent the damper 3 from falling off.

[0112] In one embodiment, the hinge shaft 5 is a screw, which passes through one of the first joint 4 and the second joint 6 and is threadedly connected to the other of the first joint 4 and the second joint 6 .

[0113] In one embodiment, Figure 5 As shown, the first joint 4 further includes an annular body and a second annular boss 405. The second annular boss 405 is arranged on the inner circumference of the annular body 403, the screw passes through the inner circumference of the second annular boss 405, and the screw head is arranged in the annular body 403.

[0114] By such arrangement, the second annular boss 405 can limit the screw head within the first joint 4. At the same time, the annular body 403 can be used to accommodate the screw head to prevent the screw head from protruding from the first joint 4 and damaging the aesthetics of the connection structure.

[0115] In addition, the first joint 4 is annular as a whole, has low injection molding difficulty, reliable dimensional stability, and the first joint 4 is efficiently installed in the second hinge hole 201, which helps to improve the assembly efficiency of the connection component.

[0116] In one embodiment, Figure 3 As shown, the connection assembly also includes a nut 7, which is arranged in the annular body 403 and sleeved outside the screw head.

[0117] The nut 7 can be used to wrap the screw head to improve the aesthetics of the connection assembly.

[0118] In one embodiment, the nut 7 is flush with the outer end of the first joint 4, which can make the appearance of the connection assembly smooth and beautiful.

[0119] In one embodiment, the second hinge hole 201 is provided with a first hole section 2011 and a second hole section 2012 in sequence in a direction close to the first hinge hole 101. The aperture of the first hole section 2011 is larger than the aperture of the second hole section 2012, and abutting surfaces are formed between the first hole section 2011 and the second hole section 2012. The third annular bosses 404 are respectively provided outside the first joint 4 and the second joint 6, and the third annular bosses 404 are provided inside the first hole section 2011 and abut against the abutting surfaces.

[0120] By such arrangement, the first joint 4 and the second joint 6 can respectively abut against the abutting surface through the third annular boss 404 , thereby limiting the damper 3 in the first hinge hole 101 .

[0121] In one embodiment, the second connector 6 is plugged into the second connector 2 .

[0122] By such arrangement, the second joint 6 and the second connecting member 2 can be relatively stationary, so when the second connecting member 2 rotates, the first joint 4 and the second joint 6 can both rotate synchronously with the second connecting member 2, and the first joint 4 and the second joint 6 will not move relative to each other, which can prevent the screw from loosening due to the relative movement of the first joint 4 and the second joint 6. In one embodiment, the second joint 6 is provided with a third plug block 601, and the hole wall of the second hinge hole 201 is correspondingly provided with a third slot capable of accommodating the third plug block 601.

[0123] According to an embodiment of the present invention, on the other hand, a device having a connection component is provided, comprising the connection component of the first aspect of the present invention.

[0124] The device with a connecting component of the second aspect of the present invention includes or uses the connecting component of the first aspect of the present invention, and thus has its beneficial effects, namely, during use of the device with a connecting component of an embodiment of the present invention, when the second connecting member 2 rotates relative to the first connecting member 1, the first joint 4 is carried to rotate, and the first joint 4 drives the damper housing 301 to rotate synchronously through the cooperation between the limiting rib 3011 and the limiting groove 401, and the damper core 302 is limited in the first hinge hole 101, so that the damper housing 301 and the damper core 302 can move relative to each other, and a damping force can be generated between the damper housing 301 and the damper core 302, which can slow down the rotation speed of the second connecting member 2, thereby avoiding the second connecting member 2 from rotating at a faster speed and colliding with the first connecting member 1, resulting in loud noise and easy damage to the first connecting member 1 or the second connecting member 2, which helps to improve user experience.

[0125] Furthermore, since the damper inner core 302 is limited in the first hinge hole 101, the damper inner core 302 can directly cooperate with the hole wall of the first hinge hole 101, and there is no need to separately set a joint to cooperate with the damper inner core 302. This saves a joint, can reduce the number of parts of the connecting assembly, makes the structure of the connecting assembly simpler and more compact, and helps to reduce the manufacturing cost of the device.

[0126] In one embodiment, the device having the connection assembly is an electric kettle, the first connection member 1 is a handle of the kettle body, and the second connection member 2 is a kettle cover.

[0127] In this embodiment, when the lid is opened, the lid can drive the first joint 4 and the damper shell 301 to rotate together, the damper core 302 and the handle are relatively still, the damper shell 301 and the damper core 302 move relative to each other, and the damping medium in the damping chamber generates a damping force to slow down the rotation speed of the lid.

[0128] When the lid is closed, the pot lid can drive the first joint 4 and the damper shell 301 to rotate together, the damper core 302 and the handle are relatively still, the damper shell 301 and the damper core 302 move relative to each other, and the damping medium in the damping chamber generates a damping force to slow down the rotation speed of the pot lid.

[0129] It should be noted that the device with the connection assembly may be an electric kettle, but is not limited thereto, and may also be a water cup, an electric rice cooker, and other products.

[0130] Although the embodiments of the present invention have been described in conjunction with 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 the appended claims.
