Description

Technical Field

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

[0002] In the related art, a hinged connection component, such as a lid hinged to a kettle body, has a finger press position behind the hinge of the lid. When the lid needs to be opened, the thumb presses the lid open. When the press position contacts the kettle handle, the lid opens to its fullest position. When the lid needs to be closed, it is simply snapped back into place.

[0003] In the related art, the lid is opened too quickly and easily falls off when closed, making loud noises and easily damaging the lid and handle, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the utility model provides a connecting assembly to solve the problem that the lid is easily dropped when closing the lid due to excessive speed when opening the lid.

[0005] In a first aspect, the present invention provides a connection assembly, comprising:

[0006] A first connecting member has a first hinge hole, and an abutment structure is provided on the inner periphery of the first hinge hole;

[0007] a second connecting member having a second hinge hole;

[0008] The damper includes a damper shell and a damper core. The damper shell can move relative to the damper core and generate a damping force. A first slot is provided on one of the damper core and the abutment structure, and a first plug is provided on the other of the damper core and the abutment structure; the first plug is inserted into the first slot; the damper shell is limited to the second hinge hole.

[0009] Beneficial effect: During use of the connecting assembly of the embodiment of the utility model, when the second connecting member rotates relative to the first connecting member, the damper shell is also rotated with it, and the damper inner core can be limited in the first hinge hole by the cooperation of the first slot and the first plug block, and is relatively stationary with respect to the first hinge hole. Therefore, the damper shell and the damper inner core can move relative to each other, and a damping force can be generated between the damper shell and the damper inner core, which can slow down the rotation speed of the second connecting member, thereby avoiding the second connecting member from rotating at a faster speed and colliding with the first connecting member, resulting in loud noise and damage to the first connecting member or the second connecting member, thereby helping to improve user experience.

[0010] In addition, the connection structure of the embodiment of the utility model can limit the inner core of the damper through the abutment structure, and there is no need to set a separate joint to limit the end of the inner core of the damper, thereby saving a joint, reducing the number of parts of the connection assembly, making the structure of the connection assembly simpler and more compact, and helping to reduce the manufacturing cost of the connection assembly.

[0011] In an optional embodiment, the connection component further includes:

[0012] A first joint, wherein a second plug-in block is provided on the first joint, a second slot is provided on the inner periphery of the second hinge hole, the second plug-in block is inserted into the second slot, and the damper housing is plugged into the second plug-in block;

[0013] The abutting structure is provided with a first avoidance groove, which extends along the circumferential direction of the first hinge hole. The second inserting block is arranged in the first avoidance groove and can rotate in the first avoidance groove.

[0014] Beneficial effect: Through such a setting, the second plug block can be inserted into the second slot, thereby limiting the first joint to the second hinge hole, so that when the second connecting member rotates, the first joint can be carried to rotate, and the first joint drives the damper shell to rotate relative to the damper core, thereby generating a damping force.

[0015] At the same time, the second plug block can be arranged in the first avoidance groove. When the first joint rotates with the second connecting member, the first joint can rotate in the first avoidance groove, so that the abutment structure can both limit the inner core of the damper and not hinder the first joint from rotating relative to the first connecting member under the drive of the second connecting member.

[0016] On this basis, in the embodiment of the present application, the first connector is limited by the second plug-in block and the second connecting piece, so that the entire first connector can be set into a ring shape, thereby facilitating the processing of the first connector, making the size of the first connector stable and reliable, and improving the assembly efficiency of the first connector.

[0017] In an optional embodiment, a limiting rib is provided on the damper housing, a limiting groove is provided on the first joint, and the limiting rib is inserted into the limiting groove;

[0018] A second avoidance groove is provided on the abutting structure. The second avoidance groove is provided in the first avoidance groove and extends along the circumferential direction of the first hinge hole. The limiting rib is provided in the second avoidance groove and can rotate in the second avoidance groove.

[0019] Beneficial effect: Through such an arrangement, the second plug block can be used to fix the first joint in the second hinge hole, and can also be used to make the first joint cooperate with the outer limit of the damper. The second plug block has multiple functions and can make the structure of the first joint simpler and more compact.

[0020] The first joint can drive the damper housing to rotate synchronously when rotating, and the second avoidance groove can allow the damper housing to rotate therein, so as to prevent the abutment structure from hindering the movement of the damper housing.

[0022] In an optional embodiment, a central angle of the first avoidance groove and / or the second avoidance groove is greater than or equal to 90 degrees.

[0023] Beneficial effect: When the second connecting member is rotated into place, the groove walls of the first avoidance groove and the second avoidance groove respectively abut against the second plug block and the limiting rib, and prevent the second connecting member from continuing to rotate, thereby restricting the rotation angle of the second connecting member.

[0024] Exemplarily, when the first connecting member in the connecting assembly is the kettle body and the second connecting member is the kettle lid, the groove walls of the first avoidance groove and the second avoidance groove can limit the kettle lid when the kettle lid is fully opened. When the central angle of the first avoidance groove and the second avoidance groove is set to be greater than or equal to 90 degrees, the kettle lid can be prevented from automatically falling when it is in the open state.

[0025] In an optional embodiment, the second hinge holes are arranged in pairs and are respectively arranged on both sides of the first hinge hole. The first joint passes through one of the second hinge holes and is plugged into the damper housing.

[0026] Beneficial effect: By setting two second hinge holes and making the first hinge hole located between the two second hinge holes, the first joint is connected to a second hinge hole and plugged into the damper housing, so that the second connecting member can be stably stressed and is not prone to shaking during rotation.

[0027] In an optional embodiment, the connection component further includes:

[0028] The second joint and the first joint are respectively provided at two ends of the damper, and the second joint is provided in the second hinge hole;

[0029] The hinge shaft passes through the first joint, the damper inner core and the second joint in sequence.

[0030] Beneficial effect: Through such a setting, the first joint can not only be used to promote the synchronous movement of the damper housing and the second connecting member, but also can be used to cooperate with the second joint to limit the damper on the first connecting member to prevent the damper from falling off.

[0031] In an optional embodiment, the hinge shaft is a screw, which passes through one of the first joint and the second joint and is threadedly connected to the other of the first joint and the second joint.

[0032] In an optional embodiment, the first connector includes:

[0033] Ring-shaped body;

[0034] The second annular boss is arranged on the inner circumference of the annular body. The screw passes through the inner circumference of the second annular boss, and the screw head of the screw is arranged in the annular body.

[0035] Beneficial effect: Through such a setting, the second annular boss can limit the screw head within the first joint. At the same time, the annular body can be used to accommodate the screw head to prevent the screw head from protruding from the first joint and damaging the aesthetics of the connection structure.

[0036] In an optional embodiment, the connecting assembly further comprises a nut, which is disposed in the annular body and sleeved on the outside of the screw head.

[0037] Advantageous effect: The nut can be used to wrap the screw head to improve the aesthetics of the connection component.

[0039] Beneficial effect: Through such an arrangement, the first joint and the second joint can respectively abut against the abutment surface through the third annular boss, thereby limiting the damper in the first hinge hole.

[0040] In an optional embodiment, the second connector is plugged into the second connecting member.

[0041] Beneficial effect: Through such a setting, the second joint and the second connecting member can be relatively stationary, so when the second connecting member rotates, the first joint and the second joint can both rotate synchronously with the second connecting member, and the first joint and the second joint will not move relative to each other, which can avoid the screw loosening due to the relative movement of the first joint and the second joint.

[0042] In a second aspect, the present invention further provides a device having a connection assembly, comprising:

[0043] A connecting assembly according to a first aspect of the present invention.

[0044] Beneficial effect: The device with a connecting component in the second aspect of the present invention includes or uses the connecting component in the first aspect of the present invention, and thus has its beneficial effect, that is, during use of the device with a connecting component in an embodiment of the present invention, when the second connecting member rotates relative to the first connecting member, the first joint is carried to rotate, and the first joint drives the damper shell to rotate synchronously through the cooperation of the limiting rib and the limiting groove, and the damper core is fixed in the first hinge hole, so that the damper shell and the damper core can move relative to each other, and a damping force can be generated between the damper shell and the damper core, which can slow down the rotation speed of the second connecting member, thereby avoiding the second connecting member rotating at a faster speed and colliding with the first connecting member, resulting in loud noise and easy damage to the first connecting member or the second connecting member, which helps to improve user experience.

[0071] 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 drawings in the embodiments of the present invention. Obviously, the embodiments described 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.

[0072] The following combination Figures 1 to 14 , describing the embodiments of the present utility model.

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

[0074] The first connecting member 1 has a first hinge hole 101, and an abutment structure is provided on the inner periphery of the 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. A second slot 2013 is provided on one of the damper inner core 302 and the abutment structure (see FIG. 2 ). Figure 7 ), a first insert block 3021 is provided on the other of the damper inner core 302 and the abutting structure (see Figure 4 ). The first insert block 3021 is inserted into the second slot 2013; the damper housing 301 is limited to the second hinge hole 201.

[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 damper shell 301 is also rotated with it, and the damper core 302 can be limited in the first hinge hole 101 by the cooperation of the first slot 1021 and the first plug block 3021, and is relatively stationary with respect to the first hinge hole 101, so that the damper shell 301 and the damper core 302 can move relative to each other, and a damping force can be generated between the damper shell 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 damage to the first connecting member 1 or the second connecting member 2, which helps to improve the user experience.

[0076] In addition, the connection structure of the embodiment of the utility model can limit the damper inner core 302 through the abutment structure, and there is no need to set a separate joint to limit the end of the damper inner core 302, thereby saving a joint, reducing the number of parts of the connection assembly, making the structure of the connection assembly simpler and more compact, and helping to reduce the manufacturing cost of the connection assembly.

[0077] In the embodiment of the present application, the damper housing 301 is limited to the second hinge hole 201, which means that the damper housing 301 can remain relatively stationary with the second hinge hole 201 and rotate synchronously with the second connecting member 2 when the second connecting member 2 rotates.

[0078] In one embodiment, multiple damping cavities are formed between the damper core 302 and the damper shell 301, and damping medium is provided in the damping cavity. 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 cavity can flow to the adjacent damping cavity 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 at intervals on the inner wall of the damper housing 301, and two third ribs are provided at intervals 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 a damping cavity.

[0081] As an alternative 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, the connection assembly further includes a first joint 4 .

[0083] Among them, such as Figure 5 As shown, the first connector 4 is provided with a second plug-in block 402. Figure 7 As shown, a second slot 2013 is provided on the inner circumference of the second hinge hole 201. The second insert block 402 is inserted into the second slot 2013, and the damper housing 301 is plugged into the second insert block 402. A first avoidance groove 1022 is provided on the abutment structure. The first avoidance groove 1022 extends along the circumference of the first hinge hole 101. The second insert block 402 is disposed within the first avoidance groove 1022 and is capable of rotating therein.

[0084] By such a configuration, the second plug block 402 can be inserted into the second slot 2013, thereby limiting the first joint 4 to the second hinge hole 201, so that when the second connecting member 2 rotates, the first joint 4 can be carried to rotate, and the first joint 4 drives the damper housing 301 to rotate relative to the damper core 302, thereby generating a damping force.

[0085] At the same time, the second plug block 402 can be arranged in the first avoidance groove 1022. When the first joint 4 rotates with the second connecting member 2, the first joint 4 can rotate in the first avoidance groove 1022, so that the abutment structure can both limit the damper inner core 302 and will not hinder the first joint 4 from rotating relative to the first connecting member 1 under the drive of the second connecting member 2.

[0086] On this basis, in the embodiment of the present application, the first connector 4 is limitedly engaged with the second connector 2 through the second plug-in 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.

[0087] 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 set to be adapted to 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.

[0088] In one embodiment, the size of the second slot 2013 along the circumference of the second hinge hole 201 can be optionally configured to be compatible with the second insert block 402 , so as to drive the first joint 4 to rotate synchronously when the second connector 2 rotates.

[0089] As a convertible implementation, in an embodiment not shown in the drawings, the size of the second slot 2013 along the circumference of the second hinge hole 201 is larger than the size of the second inserting block 402 .

[0090] By such an arrangement, when the second connecting member 2 rotates in the first direction relative to the first connecting member 1, at the beginning, the second plug block 402 can not abut against the groove wall of the second slot 2013, and the second plug block 402 can rotate in the second slot 2013. At this time, the second connecting member 2 can rotate quickly relative to the first connecting member 1.

[0091] When the second inserting block 402 abuts against the wall of the second slot 2013 , the second connecting member 2 rotates synchronously with the damper housing 301 , and causes the damper housing 301 and the damper inner core 302 to move relative to each other.

[0092] 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, generating noise, or causing damage to the first connecting member 1 or the second connecting member 2.

[0093] In one embodiment, a retaining rib 3011 is provided on the damper housing 301. A retaining groove 401 is provided on the first joint 4, into which the retaining rib 3011 is inserted. A second escape groove 1023 is provided on the abutment structure. The second escape groove 1023 is provided within the first escape groove 1022 and extends circumferentially around the first hinge hole 101. The retaining rib 3011 is disposed within the second escape groove 1023 and is capable of rotating therein.

[0094] By such an arrangement, the second plug block 402 can be used to fix 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 second plug block 402 has multiple functions and can make the structure of the first joint 4 simpler and more compact.

[0095] The first joint 4 can drive the damper housing 301 to rotate synchronously when rotating. Meanwhile, the second avoidance groove 1023 can allow the damper housing 301 to rotate therein, so as to prevent the abutting structure from hindering the movement of the damper housing 301.

[0096] As a convertible implementation, in an embodiment not shown in the accompanying drawings, a second slot 2013 is provided on the first joint 4, a limiting protrusion is provided in the second slot 2013, and a limiting groove 401 for accommodating the limiting protrusion is correspondingly provided on the damper housing 301.

[0097] As another convertible implementation, in an embodiment not shown in the drawings, the second avoidance groove 1023 is not provided on the abutment structure, and the limiting rib 3011 of the damper housing 301 can rotate in the first avoidance groove 1022 .

[0098] In one embodiment, the abutting structure is the first annular boss 102 , and the first avoidance groove 1022 and the second avoidance groove 1023 are arc-shaped grooves provided on the first annular boss 102 .

[0099] In one embodiment, a central angle between the first avoidance groove 1022 and the second avoidance groove 1023 is greater than or equal to 90 degrees.

[0100] When the second connecting member 2 is rotated into place, the groove walls of the first avoidance groove 1022 and the second avoidance groove 1023 respectively abut against the second plug block 402 and the limiting rib 3011, and prevent the second connecting member 2 from rotating further, thereby constraining the rotation angle of the second connecting member 2.

[0101] Exemplarily, when the first connecting member 1 in the connecting assembly is the kettle body and the second connecting member 2 is the kettle lid, the groove walls of the first avoidance groove 1022 and the second avoidance groove 1023 can limit the kettle lid when the kettle lid is fully opened. When the central angle of the first avoidance groove 1022 and the second avoidance groove 1023 is set to be greater than or equal to 90 degrees, the kettle lid can be prevented from automatically falling when it is in the open state.

[0102] In one embodiment, Figure 2 and Figure 3 As shown, the second hinge holes 201 are arranged in pairs and are respectively 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 .

[0103] By setting two second hinge holes 201 and making the first hinge hole 101 located between the two second hinge holes 201, the first joint 4 is connected to one 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.

[0104] For example, 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, and second hinge holes 201 are respectively provided on the groove walls on opposite sides of the connecting groove. The first hinge hole 101 of the first connecting member 1 can be provided in the connecting groove, and both ends are connected to the first second hinge hole 201.

[0105] As a convertible implementation, in an embodiment not shown in the drawings, there is only one second hinge hole 201 , which is provided at one side of the first hinge hole 101 .

[0106] 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 provided at both ends of the damper 3, and the second joint 6 is provided 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.

[0107] The hinge shaft 5 is used to connect the first joint 4, the damper 3 and the second joint 6 into one body, and to hinge the first connecting member 1 and the second connecting member 2 to each other.

[0108] By such a configuration, 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 can also 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.

[0109] 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 one of the first joint 4 and the second joint 6 .

[0110] In one embodiment, Figure 5 As shown, the first joint 4 further includes a second annular boss 405 . The second annular boss 405 is provided on the inner circumference of the annular body 403 , and the screw passes through the inner circumference of the second annular boss 405 , and the screw head is provided in the annular body 403 .

[0111] 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.

[0112] In addition, the first joint 4 is annular as a whole, has low injection molding difficulty, and has reliable dimensional stability. The first joint 4 is efficiently installed in the second hinge hole 201, which helps to improve the assembly efficiency of the connection component.

[0113] In one embodiment, Figure 3 As shown, the connection assembly further includes a nut 7, which is disposed in the annular body 403 and sleeved outside the screw head.

[0114] The nut 7 can be used to wrap the screw head to improve the aesthetics of the connection assembly.

[0115] 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.

[0116] In one embodiment, the second hinge hole 201 includes a first hole segment 2011 and a second hole segment 2012 sequentially arranged in a direction approaching the first hinge hole 101. The diameter of the first hole segment 2011 is larger than the diameter of the second hole segment 2012, and an abutment surface is formed between the first hole segment 2011 and the second hole segment 2012. A third annular boss 404 is respectively provided on the outside of the first joint 4 and the second joint 6. The third annular boss 404 is disposed within the first hole segment 2011 and abuts against the abutment surface.

[0117] By such arrangement, the first joint 4 and the second joint 6 can respectively abut against the abutting surface via the third annular boss 404 , thereby limiting the damper 3 in the first hinge hole 101 .

[0118] In one embodiment, the second connector 6 is plugged into the second connector 2 .

[0119] This arrangement allows the second joint 6 to remain relatively stationary relative to the second connector 2. Therefore, when the second connector 2 rotates, the first joint 4 and the second joint 6 can both rotate synchronously with the second connector 2, preventing relative movement between the first joint 4 and the second joint 6. This prevents the screw from loosening due to relative movement between the first joint 4 and the second joint 6. In one embodiment, the second joint 6 is provided with a third insert 601, and the wall of the second hinge hole 201 is correspondingly provided with a third slot capable of accommodating the third insert 601.

[0120] According to an embodiment of the present invention, on the other hand, a device having a connection assembly is provided, comprising the connection assembly of the first aspect of the present invention.

[0121] 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, that is, during use of the device with a connecting component in 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 shell 301 to rotate synchronously through the cooperation between the limiting rib 3011 and the limiting groove 401, and the damper core 302 is fixed in the first hinge hole 101, so that the damper shell 301 and the damper core 302 can move relative to each other, and a damping force can be generated between the damper shell 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.

[0122] Since the damper core 302 is fixedly arranged in the first hinge hole 101, the damper core 302 can directly cooperate with the hole wall of the first hinge hole 101, and there is no need to set a separate joint to cooperate with the damper core 302. This saves a joint, can reduce the number of parts of the connecting assembly, make the structure of the connecting assembly simpler and more compact, and help reduce the manufacturing cost of the device.

[0123] 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 2 is a kettle lid.

[0124] 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 stationary, 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.

[0125] When the lid is closed, 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 stationary, 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.

[0126] It should be noted that the device having 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.

[0127] Although the embodiments of the present invention are 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 shall fall within the scope of protection required by the present invention.
