[0002] Currently, most existing rope toys have an integrated design where the internal drive structure and the shell are integrated. This structure makes it difficult to replace or repair the outer shell when it is damaged or the internal battery is depleted. Users often have to discard the entire toy, which not only results in high usage costs but also wastes resources.

[0003] Furthermore, the one-piece structure limits the ease of cleaning and maintenance of the toy; with long-term use, wear and tear on the ropes or malfunction of internal electronic components cannot be replaced economically and effectively. Utility Model Content

[0004] The main purpose of this utility model is to provide a rope toy with a modular, detachable structure, low maintenance cost, and long lifespan.

[0005] To achieve the above objectives, this utility model provides a rope toy, comprising: The housing includes a first outer shell and a second outer shell detachably connected to the first outer shell, the first outer shell and the second outer shell defining a receiving cavity, the material of the first outer shell and / or the second outer shell including foamed thermoplastic polyurethane; A power core, which is detachably installed within the receiving cavity; A rope, one end of which is connected to the power core, the power core being used to drive the rope to move relative to the first housing and / or the second housing, the other end of which extends outside the housing.

[0033] Please see Figure 1 , Figure 2 as well as Figure 3 This utility model provides a rope toy 100, including a shell 10, a power core 20, and a rope 30. The power core 20 is detachably installed inside the shell 10. One end of the rope 30 is connected to the power core 20, and the power core 20 drives the rope 30 to move. The other end of the rope 30 extends outside the shell 10, allowing pets to chase, pounce, or interact with it, thereby simulating prey movement patterns and increasing the pet's interest and exercise.

[0034] The housing 10 includes a first outer shell 11 and a second outer shell 12 detachably connected to the first outer shell 11. The first outer shell 11 and the second outer shell 12, when connected, define a receiving cavity 13, within which the power core 20 is detachably disposed. The first outer shell 11 and / or the second outer shell 12 are made of foamed thermoplastic polyurethane.

[0035] The shell 10 adopts a split modular design. The first outer shell 11 and the second outer shell 12 are detachably connected, and the power core 20 within the housing cavity 13 is detachable, allowing users to quickly disassemble or replace the power core 20. This improves the maintenance and assembly efficiency of the rope toy 100. Furthermore, when the power core 20's battery is depleted, it can be replaced or recharged independently, or the shell 10 can be replaced independently without discarding the entire rope toy 100, reducing usage and replacement costs. In addition, the foamed thermoplastic polyurethane shell is less likely to shed debris that pets might accidentally ingest during repeated pulling or chewing, meaning its lifespan is longer than rubber shells. Simultaneously, the high elasticity and lightweight nature of the foamed thermoplastic polyurethane shell 10 minimizes the impact noise during pet interaction; its light weight also allows the rope toy 100 to float easily on water, satisfying pets' interactive play needs in various scenarios, including land and water. The rope toy 100 drives the rope 30 to move through the power core 20, that is, the rope 30 swings and rotates, thereby attracting the pet's attention and stimulating its hunting and playing instincts.

[0036] In some embodiments, one end of the rope 30 passes through the first outer shell 11 and is inserted into the receiving cavity 13, and the power core 20 drives the rope 30 to swing or rotate relative to the second outer shell 12. Alternatively, one end of the rope 30 is inserted into the second outer shell 12 and into the receiving cavity 13, and the power core 20 drives the rope 30 to swing or rotate relative to the first outer shell 11. In this configuration, inserting one end of the rope 30 into the receiving cavity 13 and connecting it to the power core 20 ensures that the connection between the rope 30 and the power core 20 is located inside the shell 10. This reduces the number and size of openings required for threading the rope, thereby reducing the risk of pet fur getting tangled in exposed openings or gaps during play and lowering the risk of pulling injuries.

[0037] In some embodiments, the rope toy 100 further includes a rope-fixing shell 40. A first outer shell 11 has a first opening 111 through it, and the rope-fixing shell 40 is rotatably engaged in the first opening 111. A second opening 401 is also provided through the rope-fixing shell 40, and one end of the rope 30 passes through the rope-fixing shell 40 and is inserted into the receiving cavity 13. The power core 20 drives the rope-fixing shell 40 and the rope 30 to rotate relative to the first outer shell 11. The diameter of the rope 30 is approximately the same as the diameter of the second opening 401, reducing the gap between the rope 30 and the inner wall of the second opening 401, effectively preventing the pet's claws or teeth from getting caught in the gap when playing and biting, thereby reducing the risk of pinching injuries. In addition, the rope-fixing shell 40 and the rope 30 can be disassembled and installed independently as a whole module. When the rope 30 wears out, the user does not need to replace the entire shell 10 or the power core 20, but only needs to replace the rope-fixing shell 40 and the rope 30, reducing the cost of maintenance and rope replacement.

[0038] Please see Figure 4 and Figure 5 In some embodiments, the rope toy 100 further includes a rope fixing plate 50, which is disposed within the receiving cavity 13. A fixing post 41 is provided on the side of the rope fixing shell 40 facing the receiving cavity 13. The rope fixing plate 50 is connected to the rope fixing shell 40. One end of the rope 30 is sleeved on the fixing post 41, and the other end of the rope 30 is clamped between the rope fixing shell 40 and the rope fixing plate 50. A plurality of clamping parts 51 are provided on the side of the rope fixing plate 50 facing the rope 30, and the clamping parts 51 press against the rope 30.

[0039] Specifically, the rope fixing plate 50 is provided with a first fixing hole 501, and the fixing post 41 is provided with a second fixing hole 411. The screw shank passes through the first fixing hole 501 and is screwed into the second fixing hole 411. The screw nut faces the fixing post 41 and abuts against the rope fixing plate 50, thereby achieving adjustable preload clamping. Furthermore, an elastic washer or anti-loosening washer is provided between the screw and the rope fixing plate 50, fine teeth or anti-slip textures are formed on the surface of the clamping part 51, and an elastic protective plate is clamped between the rope 30 and the metal part to disperse compressive stress, facilitating maintenance by tightening or replacing the rope 30 after long-term use. Understandably, one end of the rope 30 is clamped and fixed by the rope fixing shell 40 and the rope fixing plate 50. Since the rope fixing plate 50 is connected to the power core 20, the rope 30 is indirectly connected to the power core 20, and the power core 20 can also drive the rope 30 to move, that is, the rope 30 exhibits swinging, rotating and other movements to attract pets.

[0040] In other embodiments, the rope fixing plate 50 may be omitted, and the portion of the rope 30 passing through the first outer shell 11 may be set in the receiving cavity 13 and connected to the power core 20 by means of the cooperation of the rope end expansion knot and the undercut groove, the radial tension of the metal or engineering plastic crimp sleeve, the axial locking of the conical snap ring and the wedge block, the reverse locking after the T-shaped or mushroom head anchor is inserted, or the integrated anchor head is formed by injection molding secondary coating.

[0041] In some embodiments, the edge of the rope-fixing shell 40 is turned outward to form a retaining ring 42. The retaining ring 42 abuts against the side of the first outer shell 11 facing the receiving cavity 13, and the retaining ring 42 abuts near the edge of the first opening 111. In this way, the rope-fixing shell 40 is not easily separated from the first outer shell 11 during the rotation of the second outer shell 12 relative to the first outer shell 11. In other embodiments, the rope-fixing shell 40 can be rotatably locked in the first opening 111 and will not fall out under axial force by means of the cooperation of an annular groove and an elastic retaining spring, a bayonet-type snap-fit ​​structure, the engagement of several circumferential elastic tongues and a retaining flange, a rotating pair of a micro ball or sliding bearing and a shoulder retaining ring, and a combination of a spherical-ball-socket rotating pair and a sealing ring.

[0042] In some embodiments, the leash retainer 40 has an inwardly recessed inner side facing the receiving cavity 13 to form a receiving groove 431, within which the leash 30 and the leash retainer plate 50 are located. The leash retainer 40 has an outer side facing away from the receiving cavity 13 that protrudes from the first outer shell 11, and this outer side is curved. Thus, the exposed outer side is generally smooth, without sharp edges, and has a smooth transition, making it difficult for the pet to form a biting fulcrum when biting, slapping, or butting, reducing the probability of tearing and damage. In one specific example, the outer side is hemispherical.

[0043] In some embodiments, a spline sleeve 52 is provided in the central area of ​​the side of the rope fixing plate 50 opposite to the rope 30, and the spline 21 at one end of the output shaft of the power core 20 engages with the spline sleeve 52. Thus, the spline 21 and the spline sleeve 52 cooperate to achieve coaxial positioning and reliable torque transmission, providing advantages such as self-centering and anti-free rotation during assembly, thereby enabling the power core 20 to drive the rope 30. In other embodiments, the transmission mechanical connection can be achieved by using a D-shaped flat hole and a flat shaft, a hexagonal hole and a hexagonal shaft, a flat key or semi-circular key connection, a friction cone sleeve expansion connection, an eccentric drive of a pinion meshing with a circumferential gear ring, or a crank eccentric wheel driving a rocker arm output, etc.

[0044] In some embodiments, a locking block 432 protrudes from the inner side of the rope-fixing shell 40, and a locking groove 502 is provided on the outer edge of the rope-fixing plate 50, with the locking block 432 engaging within the locking groove 502. Thus, the rope-fixing plate 50 and the rope-fixing shell 40 form a circumferential anti-rotation engagement, preventing the rope-fixing plate 50 from slipping and spinning freely while the second shell 12 and rope 30 remain stationary during the operation of the power core 20. The locking block 432 and the locking groove 502 can be evenly distributed circumferentially to balance the force, and a small gap and lubrication layer can be provided at the engagement point to reduce noise.

[0045] Please see Figure 6In another embodiment, there are two or more second openings 401, and a rope 30 is threaded through each second opening 401. The second openings 401 can be distributed symmetrically or asymmetrically on the rope shell 40. In this way, the rope 30 can extend from the second shell 12 in a symmetrical or asymmetrical manner to form a multi-directional and multi-frequency swinging combination, which can adapt to the interaction needs of pets of different sizes and activity levels. Different ways of playing can be achieved by changing the rope 30 of different lengths or materials.

[0046] Please see Figure 7 In another embodiment, the rope 30 extending from the second outer shell 12 is knotted near its end, and the end away from the knot spreads out to form a tassel-like or brush-like structure. Flexible chew accessories such as soft rubber sheets, cloth strips, or small pieces with crinkle paper can also be strung together. This enhances the visual and tactile stimulation of the rope end, making it easier for pets to be attracted to participate in chasing and biting.

[0047] In some embodiments, the first outer shell 11 and the second outer shell 12 may be two parts of a sphere, with the two parts meeting at the circumferentially divided surfaces. Sealing ribs or flexible lips are provided at the dividing surfaces to inhibit the intrusion of dust and saliva, facilitating the assembly, maintenance and cleaning of the power core 20.

[0048] Please see Figure 2 , Figure 3 as well as Figure 5 In some embodiments, the first outer shell 11 includes a first rigid layer 112 and a first elastic layer 113 covering the outside of the first rigid layer 112. An internal thread 114 is provided on the inner side of the edge of the first rigid layer 112, and a portion of the first rigid layer 112 fills the inner wall of the first opening 111. The second outer shell 12 includes a second rigid layer 121 and a second elastic layer 122 covering the outside of the second rigid layer 121. The second rigid layer 121 protrudes from the second elastic layer 122 to form a connecting portion 123. The connecting portion 123 is provided with an external thread 124, and the internal thread 114 engages with the external thread 124.

[0049] In other embodiments, the first housing 11 and the second housing 12 may also adopt a snap-fit ​​connection with a circumferential buckle and an unlocking window, a bayonet-style swivel buckle, ultrasonic welding, hot riveting or cold riveting, magnetic positioning supplemented with mechanical anti-retraction, and a through-nail with a decorative cover, etc., to adapt to different production processes and maintenance needs.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the outermost end of the external thread 124 is provided with at least one limiting groove 125, and the innermost end of the internal thread 114 is provided with a limiting protrusion 114a, which is adapted to the limiting groove 125. In this way, when tightened to the position, a tactile positioning can be generated and a non-loosening and anti-reverse mechanism can be formed to avoid loosening caused by long-term vibration. At the same time, it can also serve as a reference for the assembly endpoint, improving consistency.

[0051] In some embodiments, the first rigid layer 112 and the second rigid layer 121 are made of engineering plastics that can withstand everyday impacts, such as ABS, PC, PC / ABS alloy, PA, or POM, or recyclable high-toughness materials. The first elastic layer 113 and the second elastic layer 122 are made of expanded thermoplastic polyurethane (E-TPU), which has the characteristics of being environmentally friendly, wear-resistant, heat-resistant, low-temperature resistant, lightweight, highly resilient, and compression-resistant. It can provide cushioning and noise reduction when pets bite or impact, and improve grip and feel.

[0052] Please see Figure 5 In some embodiments, both the first outer shell 11 and the second outer shell 12 are generally hemispherical. The second elastic layer 122 includes an arcuate surface 122a and a contact surface 122b connecting the arcuate surface 122a. The contact surface 122b is located at the end of the second elastic layer 122 away from the first outer shell 11. The curvature of the arcuate surface 122a is approximately the same as the curvature of the first outer shell 11, and the curvature of the contact surface 122b is less than the curvature of the arcuate surface 122a; for example, the contact surface 122b is a surface with a curvature close to zero. The contact surface 122b is smoothly connected to the arcuate surface 122a. Thus, the contact surface 122b allows the rope toy 100 to be placed flat on a contact surface, such as a table or the ground. During the process of the power core 20 driving the rope 30 to rotate, the balance of force is broken, and because the arc surface 122a surrounds the contact surface 122b, the rope toy 100 is easily rotated irregularly as a whole under the action of the arc surface 122a, that is, the rope toy 100 presents random movement, which is more attractive to the pet's natural instinct to explore.

[0053] Please see Figure 2 , Figure 3 and Figure 8In some embodiments, a limiting groove 201a is provided on the outer side of the power core 20, and a protrusion 131 is provided on the side of the first outer shell 11 and / or the second outer shell 12 facing the receiving cavity 13. The protrusion 131 is inserted into the limiting groove 201a to restrict the rotation of the power core 20 relative to the shell 10. Thus, when the power core 20 and the shell 10 are in a mating state, the power core 20 can effectively rotate and drive the rope 30 within the receiving cavity 13. Under the action of the rotation of the rope 30 and the arcuate surface 122a opposite to the rope 30, the shell 10 is driven to produce a random motion effect, thereby creating a significant pet attraction effect. It is understandable that if the power core 20 and the shell 10 are not reliably fixed, the shell 10 cannot rotate in sync with the rotation of the rope 30 driven by the power core 20, making it difficult for the pet to perceive the rotation effect of the rope toy 100, and the overall attraction is weakened. In other embodiments, the limiting groove 201a may be provided on the side of the first outer shell 11 and / or the second outer shell 12 facing the receiving cavity 13. Correspondingly, the protrusion 131 is provided on the outside of the power core 20.

[0054] Please see Figure 8 , Figure 9 , Figure 10 , Figure 11 In some embodiments, the power core 20 includes a top shell 201, a bottom shell 202, a mounting frame 203, and a drive assembly 22 and a control assembly 23. The top shell 201 and the bottom shell 202 are connected to form a receiving space, and the drive assembly 22 and the control assembly 23 are disposed within the mounting frame 203, which is located within the receiving space.

[0055] The drive assembly 22 includes a motor 221, an input gear 222, and an output gear 223. The input gear 222 is mounted on the output end of the motor 221, and the output gear 223 is connected to the output shaft. The input gear 222 and the output gear 223 mesh with each other for transmission. The output end of the motor 221 drives the input gear 222 to rotate. Through the meshing relationship of the gears, the output gear 223 transmits power to the output shaft, thereby achieving precise and stable power output. To further optimize the driving efficiency of the power core 20, the power core 20 can also be configured as a gearbox assembly containing multiple gears. The power output from the motor 221 is transmitted to the output shaft via the gearbox, which can precisely control the speed and force of the output shaft's movement, allowing the pet toy to exhibit diverse rope-swinging effects. The forward and reverse rotation of the motor 221 can also flexibly switch the rope-swinging direction.

[0056] The power core 20 also includes a power supply component 28, which is electrically connected to the drive assembly 22 to provide energy to the drive assembly 22. Preferably, the power core 20 is also provided with a charging port 281, which is located on the outer surface of the housing 10 and connected to the power supply component 28. Users can charge the power supply component 28 through the charging port 281, thereby reducing the need for frequent disassembly or replacement of the power supply component 28. To adapt to the pet use environment, the charging port 281 preferably adopts a sealable structure combined with a flexible waterproof plug to enhance its anti-fouling and waterproof performance, ensuring the stability of the power core 20 during long-term use.

[0057] The power core 20 further includes a sound-emitting unit 24, located inside the housing 10. The sound-emitting unit 24 emits sound during power output to attract the pet and encourage interaction with the toy. The sound-emitting unit 24 can be a buzzer, horn, or other small sound-emitting component. In one specific embodiment, the power core 20 can be programmed to first perform forward and reverse rope-swinging motions for a period of time. When the rope-swinging stops, the sound-emitting unit 24 can play sounds such as "woof" or "squeak," or simulate the pet owner's call to attract the pet. When the pet touches the toy, the power core 20 restarts the rope-swinging motion, achieving an interactive play experience.

[0058] The control component 23 includes a circuit board 231 and several electronic components 232, used to control parameters such as the start / stop, output power, and output time of the motor 221. To improve reliability, the control component 23 can also implement soft start, overcurrent and overtemperature protection, stall detection, and automatic shutdown, and enter a low-power or sleep mode when there is no interaction for a long time. The control component 23 can also be electrically connected to sensors 233, such as a photosensor and an accelerometer. The photosensor can detect the illumination in the housing cavity 13. When a bright state is detected, it is determined to be an installation or removal state and the motor 221 is not started; when a dark state is detected, it is determined to be in a running state and the motor 221 is allowed to run. The accelerometer is used to detect the acceleration signal caused by the pet touching it. When there is a touch, it is fed back to the control component 23 to trigger a new interaction mode.

[0059] In addition, the power core 20 may also be equipped with a function key 26 and an indicator light 27. The function key 26 is electrically connected to the control component 23 and is used to switch between sports modes, while the indicator light 27 is used to display the current mode or battery status. Sports modes may include passive mode, normal mode, and mild mode, with different scrolling and jumping patterns, frequencies, and durations in each mode. The indicator light 27 can indicate the mode and battery status through different colors or flashing patterns; for example, green indicates passive mode or charging complete, blue indicates normal mode, purple indicates mild mode, fast red flashing indicates low battery, and slow yellow flashing indicates charging.

[0060] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
