A first aspect of the utility model discloses a connection structure 5000 and a second aspect of the utility model discloses a toy. The application of the connection structure 5000 to a toy will be described below as an example, and it will be appreciated that the connection structure 5000 disclosed in the present utility model is not limited to application to toys, but may be applied to other products.

As shown in connection with fig. 4 to 11, in some embodiments of the present utility model, the connection structure 5000 includes an inner chuck 5100, an outer chuck 5200 and a torsion spring 5400, the inner chuck 5100 being adapted to be driven to rotate, and a first fixing portion 5110 is provided; the outer clamping plate 5200 is suitable for being connected with the movable piece 2000, is opposite to the inner clamping plate 5100, forms a clamping cavity 5300 with the inner clamping plate 5100, is configured to be rotatably arranged, and is provided with a second fixing part 5210; the torsion spring 5400 is constrained to the clamping cavity 5300 and has a first end 5410 and a second end 5420, and the first fixing portion 5110 and the second fixing portion 5210 are disposed between the first end 5410 and the second end 5420. Form clamping cavity 5300 between interior chuck 5100 and the outer chuck 5200, set up torsional spring 5400 in the clamping cavity 5300, when interior chuck 5100 is driven, interior chuck 5100 rotates and drives torsional spring 5400 and then drive outer chuck 5200 and rotate, thereby realize the action of connecting in the moving part 2000 of outer chuck 5200, if outer chuck 5200 receives external force to interfere, because the existence of torsional spring 5400 provides certain flexibility, torsional spring 5400 deformation produces the damping sense, prevent external force direct transfer to interior chuck 5100 and then transmit to drive in chuck 5100 pivoted structure, avoid damaging, when the external force that outer chuck 5200 received disappears, torsional spring 5400 can drive outer chuck 5200 and reset, then drive the moving part 2000 that is connected in outer chuck 5200 and reset, through using this connection structure 5000, can promote the feel and the durability of toy.

Specifically, the toy is an animal-like product, such as a dog-like dog, comprising a torso 1000, a tail 3000, a head 4000, limbs 2000, a driving device 6000, and a connecting structure 5000. The head 4000 is internally provided with a dot matrix module which is connected with a control module, and a user can simulate various expressions according to different lighting modes by controlling the lamps of the dot matrix module through a circuit. For example, after the toy is powered on, the control module controls the dot matrix module to work. Or the toy is provided with a remote controller which is in radio connection with the control module, and the remote controller sends an instruction to the control module so as to control the dot matrix module to work. It can be understood that the lattice module is mainly assembled by a plurality of LEDs, and different expressions are formed by controlling the on/off of the number of LEDs.

As shown in connection with fig. 2 to 5, the inner chuck 5100 is adapted to be driven, i.e., the inner chuck 5100 is rotated by driving of the driving means 6000, it will be appreciated that the driving means 6000 is in driving connection with the inner chuck 5100 to drive the inner chuck 5100 to rotate, i.e., the driving connection may be direct, or indirect, the driving force is transmitted to the inner chuck 5100, the inner chuck 5100 has a first fixing portion 5110, and the first fixing portion 5110 is a member for interacting with the torsion spring 5400.

The outer cartridge 5200 is adapted to be connected to a movable member 2000, the so-called movable member 2000, i.e. the movable member 2000 needs to be designed to be movable in the product, the limb 2000 mentioned above being the movable member 2000. It will be appreciated that the outer cartridge 5200 and the limb 2000 are coupled together, i.e., are relatively immovable, such that the inner cartridge 5100, when rotated by the outer cartridge 5200, moves the limb 2000. Since the outer clamp 5200 is designed to be rotatable, the outer clamp 5200 is rotated when the limb 2000 is rotated. The outer chuck 5200 has a second fixing portion 5210, and the second fixing portion 5210 is a member for interacting with the torsion spring 5400.

As shown in fig. 6, a clamping cavity 5300 is formed between the inner clamping disc 5100 and the outer clamping disc 5200, so-called clamping cavity 5300 can be accommodated in the clamping cavity 5300, and the torsion spring 5400 is also restrained in the clamping cavity 5300, so-called restraint, that the torsion spring 5400 is difficult to separate from the clamping cavity 5300, so that the torsion spring 5400 can generate force on the inner clamping disc 5100 and the outer clamping disc 5200, and the torsion spring 5400 cannot fly to separate from the clamping cavity 5300 under the restraint condition. The torsion spring 5400 is formed by twisting metal steel screw, for example, so that two ends, namely a first end 5410 and a second end 5420, are formed, the first fixing portion 5110 and the second fixing portion 5210 are located between the first end 5410 and the second end 5420, so that the inner chuck 5100 can drive the outer chuck 5200 to rotate, and the outer chuck 5200 can avoid transmitting force to the inner chuck 5100 and then to the driving device 6000 when being stressed, thereby preventing the driving connection between the driving device 6000 and the inner chuck 5100 from being damaged.

When the driving device 6000 drives the inner chuck 5100 to rotate forward, the first fixing portion 5110 of the inner chuck 5100 abuts against the first end 5410, the second end 5420 has a tendency to follow rotation and abuts against the second fixing portion 5210, and since the outer chuck 5200 is rotatably provided, the outer chuck 5200 is caused to follow forward rotation. When the driving device 6000 drives the inner chuck 5100 to rotate reversely, the first fixing portion 5110 of the inner chuck 5100 abuts against the second end 5420, and similarly, the first end 5410 is made to rotate following the inner chuck 5100, and the first end 5410 abuts against the second fixing portion 5210, thereby causing the outer chuck 5200 to rotate following reversely. The action of the driving device 6000 realizes the rotation of the inner clamping disc 5100, and the inner clamping disc 5100 rotates to drive the torsion spring 5400 to transmit force to the outer clamping disc 5200, so that the action of the limb 2000 is realized. By arranging the driving device 6000, the toy can automatically act, for example, the toy is provided with a control module, and after the toy is electrified, the control module controls the action of the driving device 6000 according to a preset program, so that the action of the limb 2000 is realized.

When the limb 2000 is manually rotated (broken) to rotate the outer chuck 5200 forward, the second fixing portion 5210 of the outer chuck 5200 abuts against the first end 5410, the second end 5420 has a tendency to rotate following the outer chuck 5200 and abuts against the first fixing portion 5110, and the torsion spring 5400 is elastically deformed to generate damping, so that the manual force is prevented from being directly transmitted to the inner chuck 5100 and then to the driving device 6000, and the driving connection between the inner chuck 5100 and the driving device 6000 is prevented from being damaged. If the driving device 6000 is in the non-working state, due to the torsion spring 5400, when the limb 2000 is manually rotated (broken) with force, a certain damping sense can be provided, the play fun is improved, and when the manual force disappears, the limb 2000 can be smoothly reset under the action of the torsion spring 5400.

As shown in connection with fig. 6 and 8, in some embodiments of the present utility model, for convenience in restraining the torsion spring 5400, one of the inner chuck 5100 and the outer chuck 5200 is provided with a first boss 5120 facing the other of the inner chuck 5100 and the outer chuck 5200, and at this time, the torsion spring 5400 may be sleeved on the first boss 5120 to be restrained.

Specifically, taking the example that the inner chuck 5100 is provided with the first protrusion 5120 as an example, the outer chuck 5200 is provided with the first protrusion 5120 to achieve similar technical effects, and the detailed description is not repeated. The first protruding columns 5120 extend towards the outer chuck 5200, the first protruding columns 5120 can extend along the rotation axis of the inner chuck 5100, so that when the inner chuck 5100 rotates, the movement amplitude of the torsion spring 5400 cannot be excessively large, the torsion spring 5400 can be sleeved on the first protruding columns 5120 through the first protruding columns 5120, the torsion spring 5400 is effectively restrained, and when the torsion spring 5400 receives the force exerted by the first fixing portion 5110 and/or the second fixing portion 5210, the torsion spring 5400 cannot be easily sprung out to be separated from the clamping cavity 5300.

Alternatively, as shown in connection with fig. 9-11, in some embodiments of the present utility model, since one of the inner and outer trays 5100, 5200 is provided with a first protrusion 5120, then the other of the inner and outer trays 5100, 5200 is provided with a second recess 5230, the first protrusion 5120 is inserted into the second recess 5230 to achieve a male-female fit, and the outer tray 5200 can be supported by the inner tray 5100 to achieve a rotatable arrangement. It will be appreciated that the radial cross section of the second concave hole 5230 needs to be designed into a circular shape, while the radial cross section of the first convex column 5120 is also circular, and the two concave-convex matching can realize rotatable matching, so that when the outer clamping plate 5200 is subjected to external force, the outer clamping plate 5200 can rotate and then deform the torsion spring 5400.

In some embodiments of the utility model, as shown in connection with fig. 10, the first stud 5120 is provided with a first stud segment 5121 and a second stud segment 5122, the radial dimension of the first stud segment 5121 being greater than the radial dimension of the second stud segment 5122, i.e., the first stud segment 5121 appears thicker in the radial direction and the second stud segment 5122 appears relatively smaller. The first thick column section 5121 is easier to restrain the torsion spring 5400, the torsion spring 5400 is sleeved on the first column section 5121 to effectively avoid loosening, the second smaller column section 5122 is suitable for being in rotatable fit with the second concave hole 5230, and the outer clamping disc 5200 is prevented from being oversized, so that the arrangement of the structure is prevented from being influenced.

Optionally, in some embodiments of the present utility model, as shown in fig. 10, the constraint on the torsion spring 5400 may be further achieved by providing the first boss 5120 with a first post segment 5121 and a second post segment 5122, where the first boss 5120 is specifically inserted into the second concave hole 5230 through the second post segment 5122 to achieve rotation, and the outer periphery of the first post segment 5121 is provided with support ribs 5123 arranged along the outer periphery of the first post segment 5121, and since the support ribs 5123 are arranged alternately, the torsion spring 5400 can be conveniently sleeved on the first post segment 5121 and pressed and snapped onto the support ribs 5123, so that the torsion spring 5400 can be tightly snapped on the support ribs 5123 to form a few action points, thereby enhancing the constraint on the torsion spring 5400, and making the torsion spring 5400 not easy to fly. Of course, in this case, the radial dimension of the first column segment 5121 can also be greater to more effectively accommodate the installation of the torsion spring 5400.

As shown in fig. 9 and 10, in some embodiments of the present utility model, when the inner chuck 5100 is provided with the first boss 5120, a first concave hole 5130 opened away from the outer chuck 5200 is provided on the back side of the first boss 5120, so that the space volume occupied by the first boss 5120 can be fully utilized, and the first concave hole 5130 is also conveniently connected with the driving device 6000. As will be appreciated hereinafter, the spindle 1100 may be inserted into the first recess 5130, and as the inner chuck 5100 needs to be driven to rotate by the driving device 6000, the spindle 1100 and the first recess 5130 may not be rotated relative to each other. However, at least a portion of the first recess 5130 has a non-circular cross-sectional shape in the radial direction, so that the radial cross-sectional shape of the rotating shaft 1100 is also non-circular, for example, square, and thus the rotating shaft 1100 can rotate to drive the inner chuck 5100 to rotate, thereby reducing the structural complexity.

Alternatively, as shown in connection with fig. 1, in some embodiments of the utility model, the first securing portion 5110 extends toward the outer chuck 5200 and the second securing portion 5210 extends toward the inner chuck 5100, that is, the first and second securing portions 5110, 5210 are located at the periphery of the clamping cavity 5300, which facilitates engagement between the first and second ends 5410, 5420.

Alternatively, as shown in fig. 6 to 8 and fig. 10 and 11, in some embodiments of the present utility model, a stopper 5240 is provided on one of the outer tray 5200 and the inner tray 5100, and the stopper 5240 is configured to abut against the first fixing portion 5110 or the second fixing portion 5210, so that the first end 5410 and the second end 5420 can be effectively prevented from being separated from the first fixing portion 5110 and the second fixing portion 5210.

Specifically, if the limiting portion 5240 is not provided, when the limb 2000 is excessively rotated by a person, the outer chuck 5200 will also excessively rotate relative to the inner chuck 5100, and at this time, the elastic deformation of the torsion spring 5400 exceeds the limit, so that the first end 5410 and the second end 5420 are separated from the first fixing portion 5110 and the second fixing portion 5210, that is, the first fixing portion 5110 and the second fixing portion 5210 are no longer located between the first end 5410 and the second end 5420, the first fixing portion 5110 and the second fixing portion 5210 no longer interact with the first end 5410 and the second end 5420, the inner chuck 5100 cannot realize normal driving of the outer chuck 5200, and when an external force is applied to rotate the limb 2000, the outer chuck 5200 is no longer acted by the torsion spring 5400, and the torsion spring 5400 can no longer reset the outer chuck 5200. Therefore, by providing the stopper portion 5240, the stopper portion 5240 is configured to abut against the first fixing portion 5110 or the second fixing portion 5210, thereby preventing the outer chuck 5200 from being excessively rotated.

For example, the limiting portion 5240 is disposed on the outer chuck 5200, and when the outer chuck 5200 rotates at a predetermined position, the limiting portion 5240 on the outer chuck 5200 can abut against the first fixing portion 5110 of the inner chuck 5100, so that two corresponding limiting portions 5240 can be disposed to accommodate forward and reverse rotation of the outer chuck 5200. For another example, the limiting portion 5240 is disposed on the inner chuck 5100, and when the outer chuck 5200 rotates to a predetermined position, the limiting portion 5240 on the inner chuck 5100 abuts against the second fixing portion 5210 of the outer chuck 5200, and by disposing the limiting portion 5240, the rotation range of the outer chuck 5200 is restricted, and the connection structure 5000 is prevented from being disabled.

As shown in fig. 2 and 6, in some embodiments of the present utility model, the outer chuck 5200 has a second boss 5220 facing away from the inner chuck 5100, and the limb 2000 may be connected to the second boss 5220, and it is understood that since the outer chuck 5200 is to rotate the limb 2000, the connection between the second boss 5220 and the limb 2000 is relatively fixed, for example, at least part of the second boss 5220 has a non-circular cross-sectional shape in a radial direction, and a fastening hole (not shown) may be provided in the limb 2000, the cross-section of the fastening hole is also non-circular, for example, square, and the second boss 5220 is inserted into the fastening hole, so that the fastening connection can be achieved with a simple structure.

Alternatively, as shown in fig. 2 and 3, the driving device 6000 is configured to drive the connection structure 5000 by cooperating with the rotating shaft 1100. The pivot 1100 sets up at body 1000 and tip and interior chuck 5100 are connected, and limbs 2000 then are connected with outer chuck 5200, and drive arrangement 6000 sets up at body 1000, and drive arrangement 6000 drive pivot 1100 rotates, thereby the rotation of pivot 1100 drives interior chuck 5100 and rotates, and interior chuck 5100 rotates and then drives outer chuck 5200 and rotates, then makes limbs 2000 appear certain scope swing. The driving device 6000 comprises a driver 6100 and a tooth case 6200, the tooth case 6200 is a gear box, that is, the driver 6100 drives the rotation shaft 1100 to rotate in a gear transmission manner, the rotation shaft 1100 drives the inner chuck 5100 to rotate and then drives the outer chuck 5200 to rotate, and due to the arrangement of the connection structure 5000, if the limb 2000 is manually broken off (rotated), external force is difficult to be directly transmitted to the tooth case 6200, and the tooth case 6200 is prevented from being damaged.

For example, the shaft 1100 includes two, a front shaft 1101 and a rear shaft 1102, respectively; the driving device 6000 comprises two driving devices, wherein one driving device is in driving connection with the front rotating shaft 1101, and the other driving device is in driving connection with the rear rotating shaft 1102; the limb 2000 includes four limbs, two limbs 2000 constituting the front limb 2100 and the other two limbs 2000 constituting the rear limb 2200, the front limb 2100 being connected to the front rotation shaft 1101 by the connection structure 5000, and the rear limb 2200 being connected to the rear rotation shaft 1102 by the connection structure 5000. It will be appreciated that the toy need not be animal-like in shape, but may be other shapes.

In some embodiments of the present utility model, as shown in fig. 3, a part of the outer clamping plate 5200 is located in the body 1000, and another part of the outer clamping plate 5200 is located outside the body 1000, specifically, the second boss 5220 is exposed from the body 1000 through the body 1000, so that a part of the outer clamping plate 5200 is clamped in the body 1000, thereby hiding the torsion spring 5400, preventing exposure, and protecting the connection structure 5000.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
