Description

Technical Field

[0001] The present application relates to the technical field of toy devices, in particular to a telescopic toy. Background Art

[0002] Retractable toys, such as the golden hoop and lightsaber toys, are not only loved by children, but sometimes adults also love to play with them and experience the cool feeling of the protagonists in film and television dramas wielding classic weapons.

[0003] In the prior art, one is a conventional telescopic toy, which has no automatic power. The toy needs to be manually pressed back step by step from the end of the elastically extended rod. When the toy needs to be extended and lengthened, the buckle switch is pressed to instantly release the extension using the elastic explosive force of the spring.

[0004] With the improvement of technology, there is now an automatic telescopic rod with an active power source mechanism as the telescopic control structure of the telescopic toy. The current patent application number is CN202895229U. The patent document discloses a tension-type robot telescopic arm, which uses a mechanism composed of a motor, a groove wheel, a wire rope, and a spring to form automatic telescopic. This telescopic mechanism has several disadvantages. First, it is very dependent on the accuracy of the number of rotations of the motor. The speed difference phenomenon of the motor operation is a very difficult problem to overcome. If the motor shaft drives the groove wheel to rotate and the release amount of the wire rope is insufficient, the telescopic rod cannot be fully released and extended; if the motor shaft drives the groove wheel to rotate and the release amount of the wire rope is excessive, then the groove wheel will reel the wire rope back to the groove wheel from another direction, which also causes the telescopic rod to be unable to be fully released and extended; or the wire rope is rolled into a loose winding state and entangled with other structures. Second, after the telescopic product is used, it is easy to store it and often adjusted back to the retracted state. The spring inside is more compressed, which easily reduces the life of the spring. Even if the release amount of the wire rope is accurate, the telescopic rod cannot be fully extended, affecting the user experience. Utility Model Content

[0005] The utility model mainly aims at the above problems and proposes a telescopic toy, aiming to solve the technical problems in the background technology.

[0006] To achieve the above object, the utility model provides a telescopic toy, comprising:

[0007] A handheld part, wherein a driving motor and a winding wheel connected to a power output shaft of the driving motor are arranged in the housing of the handheld part;

[0008] A first telescopic rod, one end of which is connected to the hand-held part; the first telescopic rod comprises a plurality of retractable first telescopic sections, and when the first telescopic rod is in an extended state, the outer diameters of the plurality of first telescopic sections gradually decrease from the direction close to one end of the hand-held part to the direction away from the hand-held part;

[0009] A first elastic member, the first elastic member is arranged in the first telescopic section of the first telescopic rod farthest from the handheld portion, and one end of the first elastic member is connected to the end of the first telescopic section;

[0010] A rope body, one end of which extends into the first telescopic section of the first telescopic rod farthest from the handheld portion and is connected to the other end of the first elastic member, and the other end of which is connected to the winding wheel;

[0011] The second elastic member has two ends which respectively abut against the bottom end of the first telescopic section which is farthest from the hand-held part and the first telescopic section which is arranged close to the hand-held part.

[0012] Furthermore, it includes a second telescopic rod arranged in the inner cavity of the first telescopic rod, and the second elastic member is a cylindrical spring; one end of the second telescopic rod is connected to the hand-held part, and when the second telescopic rod is in an extended state, the other end abuts against the first telescopic section of the first telescopic rod farthest from the hand-held part; the second telescopic rod includes a plurality of retractable second telescopic sections, and when the second telescopic rod is in an extended state, the outer diameters of the plurality of second telescopic sections gradually decrease from the two ends close to the hand-held part to the direction away from the hand-held part; and one end of each second telescopic section away from the hand-held part is provided with a stop ring edge larger than the inner diameter of the subsequent second telescopic section.

[0013] Furthermore, it includes a battery, a control board, and a sensor arranged in the handheld part; the control board, the drive motor, the battery, and the sensor are electrically connected; the sensor is used to identify the retracted and extended state of the first telescopic rod; the control board is connected to a button switch exposed from the handheld part.

[0014] Furthermore, the control panel is provided with a charging interface.

[0015] Furthermore, the winding wheel is connected to the power output end of the driving motor through a reducer.

[0016] Furthermore, the second elastic member is a cylindrical spring; the second elastic member is sleeved on the second telescopic section with the smallest outer diameter in the second telescopic rod.

[0017] Furthermore, the elastic force of the first elastic member is smaller than the elastic force of the second elastic member.

[0018] Compared with the prior art, the telescopic toy provided by the utility model can provide an additional first elastic member in the first telescopic section of the first telescopic rod farthest from the handheld part, and the two ends are respectively connected to the rope body and the end of the first telescopic section, and has elastic potential energy for pulling the end of the rope body toward the end of the first telescopic section;

[0019] Then when the driving motor is controlled, the rope is released from the winding wheel, so that the first telescopic rod changes from a contracted state to an expanded state. If the rope is released too much, the first elastic member pulls the end of the rope to straighten the loose rope and store it in the inner cavity of the first telescopic section at the very end.

[0020] When the driving motor is controlled to release the rope from the reel, if the length of the released rope is the normal length, the first elastic member is in a semi-stretched state. If the rope is not released completely, the elastic force of the first elastic member to maintain its normal length will increase the pulling force on the rope, so that it is stretched to the predetermined release length, thereby ensuring that the first telescopic rod can be fully extended. In this way, it can compensate for the insufficient extension of the first telescopic rod and automatically adjust the speed difference of the driving motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Please refer to Figure 1-Figure 7 , this embodiment provides a telescopic toy, including:

[0034] A handheld part 1, wherein a driving motor 2 and a winding wheel 3 connected to a power output shaft of the driving motor 2 are arranged in the housing of the handheld part 1;

[0035] A first telescopic rod 4, one end of which is connected to the handheld portion 1; the first telescopic rod 4 comprises a plurality of retractable first telescopic sections 410, and when the first telescopic rod 4 is in an extended state, the outer diameters of the plurality of first telescopic sections 410 gradually decrease from one end close to the handheld portion 1 to a direction away from the handheld portion 1;

[0036] A first elastic member 6, wherein the first elastic member 6 is disposed in the first telescopic section 410 of the first telescopic rod 4 which is farthest from the handheld portion 1, and one end of the first elastic member 6 is connected to an end of the first telescopic section 410;

[0037] A rope body 14, one end of which extends into the first telescopic section 410 of the first telescopic rod 4 farthest from the handheld part 1 and is connected to the other end of the first elastic member 6, and the other end of which is connected to the winding wheel 3;

[0038] The second elastic member 7 has two ends which respectively abut against the bottom end of the first telescopic section 410 which is farthest from the hand-held part 1 and the first telescopic section 410 which is arranged close to the hand-held part 1 .

[0039] The telescopic toy has an additional first elastic member 6 disposed in the first telescopic section 410 of the first telescopic rod 4 which is farthest from the handheld part 1, and the two ends of the first elastic member 6 are respectively connected to the rope body 14 and the end of the first telescopic section 410, so as to have elastic potential energy for pulling the end of the rope body 14 toward the end of the first telescopic section 410;

[0040] Then, when the driving motor 2 is controlled, the rope is released from the reel 3, so that the first telescopic rod 4 changes from a contracted state to an extended state. If the rope is released too much, although it does not affect the elastic force of the second elastic member 7 to resist the release of the first telescopic rod 4, the rope that is released too much will be loosely piled up in the inner cavity of the first telescopic rod 4, and it is easy to have an adverse effect of entanglement with other components in the inner cavity of the first telescopic rod 4. Then, under the pulling of the first elastic member 6 on the end of the rope 14, the loose rope can be straightened and stored in the inner cavity of the first telescopic joint 410 at the very end.

[0041] When the driving motor 2 is controlled to release the rope from the winding wheel 3, if the length of the released rope is the normal length, the first elastic member 6 is in a semi-stretched state. If the rope is not fully released, the elastic force of the first elastic member 6 maintaining its normal length will increase the pulling force on the rope, so that it is stretched to the predetermined release length, thereby ensuring that the first telescopic rod 4 can be fully extended. In this way, it can compensate for the insufficient extension of the first telescopic rod 4 and automatically adjust the speed difference of the driving motor 2.

[0042] In a preferred embodiment, one end of the first elastic member 6 is connected to the end of the first telescopic section 410. The first elastic member 6 is a spring. Naturally, without the action of external force, the length of the first elastic member 6 is half the length of the first telescopic section 410, which is also the ideal length state when the first telescopic rod 4 is fully extended or contracted and folded.

[0043] Please refer to Figure 2 and Figure 4 , including a second telescopic rod 8 arranged in the inner cavity of the first telescopic rod 4, one end of the second telescopic rod 8 is connected to the hand-held part 1, and when the second telescopic rod 8 is in an extended state, the other end abuts against the first telescopic section 410 of the first telescopic rod 4 farthest from the hand-held part 1; the second telescopic rod 8 includes a plurality of retractable second telescopic sections 810, and when the second telescopic rod 8 is in an extended state, the outer diameters of the plurality of second telescopic sections 810 gradually decrease from the two ends close to the hand-held part 1 to the direction away from the hand-held part 1; each of the second telescopic sections 810 is provided with a stop ring edge 811 at one end away from the hand-held part 1, which is larger than the inner diameter of the subsequent second telescopic section 810.

[0044] The second elastic member 7 is a cylindrical spring; the second elastic member 7 is sleeved on the second telescopic section 810 with the smallest outer diameter in the second telescopic rod 8 .

[0045] By providing the second telescopic rod 8, the first telescopic rod 4 can obtain internal support when extended, so that the length of the telescopic toy can be made longer, further improving the user experience.

[0046] Moreover, the second telescopic joint 810 can also provide support and guidance for the second elastic member 7, thereby improving the operating stability of the second elastic member 7. The stop ring edge 811 can prevent the second telescopic joint 810 with a smaller outer diameter from being completely retracted into the second telescopic joint 810 with a larger outer diameter when the second telescopic joint 810 of the second telescopic rod 8 contracts, thereby preventing a malfunction.

[0047] Please refer to Figure 2 and Figure 5 , including a battery 9, a control board 10, and a sensor 11 arranged in the handheld part 1; the control board 10, the drive motor 2, the battery 9, and the sensor 11 are electrically connected; the sensor 11 is used to identify the retracted and extended state of the first telescopic rod 4; the control board 10 is connected to a button switch 12 exposed from the handheld part 1.

[0048] In some embodiments, the sensor 11 is a pressure sensor, which is set corresponding to the innermost first telescopic section 410 in the retracted state of the first telescopic rod 4. When the first telescopic rod 4 is in the retracted state, the sensor 11 resists the end of the innermost first telescopic section 410 in the first telescopic rod 4. When the first telescopic rod 4 is in the expanded state, the end of the innermost first telescopic section 410 in the first telescopic rod 4 leaves the sensor 11, so that the retracted and extended state of the first telescopic rod 4 can be identified, thereby avoiding the incorrect steering of the driving motor 2 and the inability to correctly retract and release the rope body.

[0049] The control panel 10 is provided with a charging interface.

[0050] Please refer to Figure 5 The winding wheel 3 is connected to the power output end of the driving motor 2 through a reducer 13.

[0051] Preferably, the elastic force of the first elastic member is smaller than the elastic force of the second elastic member.

[0052] Please refer to Figure 8 In some embodiments, a movable part 5 is provided in the first telescopic section, specifically, the movable part 5 is provided in the first telescopic section 410 of the first telescopic rod 4 which is farthest from the handheld part 1, and the outer wall is slidably connected to the first telescopic section 410, the rope body is indirectly connected to the first elastic member through the movable part 5, and the movable part 5 separates the rope body from the first elastic member to prevent the rope body from being released too much and causing a tangling failure with the first elastic member which is a cylindrical spring. The movable part 5 is slidably connected to the first telescopic section 410, and can also guide the contraction or expansion direction of the first elastic member.
