Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a power mechanism and a pet toy. Background Technology

[0002] Currently, with the rapid development of the pet economy, pet toys have gradually become an important part of pets' daily lives. Most mainstream electric or manual pet toys on the market, whether driven by an internal motor or a simple mechanical structure, have their appearance and movement trajectory fixed at the factory, making them impossible to modify during use. For example, common toys like rolling balls, cat wands, and toy cars only roll, swing, or move in one direction, lacking sustained novelty to stimulate a pet's senses. In other words, intelligent pets quickly grasp the pattern after a brief period of curiosity, leading to a rapid decline in interest and the toy becoming unused.

[0003] Secondly, pet behavior studies indicate that animals such as dogs and cats maintain longer attention spans for unpredictable or explorable stimuli. However, existing products fail to provide dynamic structures that can flexibly adjust to different scenarios or the pet's developmental stage. Therefore, breaking through fixed forms and single action patterns has become a pressing technical challenge for the current pet toy industry. Utility Model Content

[0024] Currently, with the rapid development of the pet economy, pet toys have gradually become an important part of pets' daily lives. Most mainstream electric or manual pet toys on the market, whether driven by an internal motor or a simple mechanical structure, have their appearance and movement trajectory fixed at the factory, making them impossible to modify during use. For example, common toys like rolling balls, cat wands, and toy cars only roll, swing, or move in one direction, lacking sustained novelty to stimulate a pet's senses. In other words, intelligent pets quickly grasp the pattern after a brief period of curiosity, leading to a rapid decline in interest and the toy becoming unused.

[0025] Secondly, pet behavior studies indicate that animals such as dogs and cats maintain longer attention spans for unpredictable or explorable stimuli. However, existing products fail to provide dynamic structures that can flexibly adjust to different scenarios or the pet's developmental stage. Therefore, breaking through fixed forms and single action patterns has become a pressing technical challenge for the current pet toy industry.

[0026] The following explanation is based on the accompanying drawings.

[0027] Reference Figure 1 , 47, 12, and 13, embodiments of this utility model provide a power mechanism 1 for detachable connection with different outer shell accessories 2. By combining the power mechanism 1 with the outer shell accessories 2 in different ways, pet toys 10 with different shapes and different movement states can be formed. This solves the limitation of "one toy = one way to play" in the prior art, and enables the pet toy 10 to produce differentiated forms according to the combination of different outer shell accessories 2 with the same power mechanism 1. This is more in line with the exploratory nature of pets and keeps the pets happy to play with the pet toy 10.

[0028] Reference Figure 1 , 2 According to embodiments 6 and 8 of this utility model, a power mechanism 1 is used to connect with a housing accessory 2 to present the shape of a pet toy 10. The power mechanism 1 includes a housing 11, a drive assembly 12 is installed inside the housing 11, and a transmission shaft 13 is installed along the central axis of the housing 11. The transmission shaft 13 is connected to the drive assembly 12 and extends out of the housing 11. Each end of the transmission shaft 13 is provided with a first connecting part 14, which is used for transmission connection with the housing accessory 2. A second connecting part 15 is provided on one side of the housing 11. The second connecting part 15 is on the same side as the first connecting part 14 at one end of the transmission shaft 13. The second connecting part 15 is used for non-transmission connection with the housing accessory 2. There is a clearance gap 111 between the second connecting part 15 and the first connecting part 14.

[0029] Understandably, the power mechanism 1 and different outer casing accessories 2 can be detachably connected via the first connecting portion 14 at both ends of the drive shaft 13 or via the second connecting portion 15 on one side of the housing 11 and the first connecting portion 14 on different sides of the second connecting portion 15 to form pet toys 10 of different shapes.

[0030] Specifically, compared with the prior art, the housing 11 has a first connecting portion 14 and a second connecting portion 15 on the same side, and a first connecting portion 14 on the other side of the housing 11. If the housing accessory 2 is connected to the first connecting portion 14, it can be driven by the drive shaft 13; if the housing accessory 2 is connected to the second connecting portion 15, it cannot be driven by the drive shaft 13. (Refer to...) Figure 5When the first connecting part 14 is connected to the outer casing accessory 2, due to the clearance 111, the second connecting part 15 on the same side does not affect the connection of the first connecting part 14 and the transmission of the drive shaft 13. When the second connecting part 15 is connected to the outer casing accessory 2, due to the clearance 111, the first connecting part 14 and the drive shaft 13 on the same side will be suspended in the transmission, and the outer casing accessory 2 connected to the second connecting part 15 will not be transmitted with the drive shaft 13. That is, the power mechanism 1 is provided with a first connecting part 14 for transmission connection and a second connecting part 15 for non-transmission connection on the same side, supporting multiple assembly methods of double-sided transmission or single-sided transmission, and a clearance 111 is reserved between the second connecting part 15 and the first connecting part 14 to avoid interference with the assembly of the first connecting part 14 or the second connecting part 15.

[0031] Understandably, in the first assembly method: the power mechanism 1 connects to two outer shell fittings 2 via the first connecting portions 14 at opposite ends of the drive shaft 13 extending outside the housing 11, and the power mechanism 1 is encased by the two outer shell fittings 2 to form a pet toy 10 in the shape of the outer shell fittings 2. The drive assembly 12 outputs power to the drive shaft 13, and the first connecting portions 14 at opposite ends of the drive shaft 13 are connected to the two outer shell fittings 2, that is, the power is transmitted to the outer shell fittings 2, thereby causing the pet toy 10 to be in a rolling or moving motion state to attract pets to interact and play. In the second assembly method: the power mechanism 1 connects to two outer shell fittings 2 via the second connecting portion 15 on one side of the housing 11 and the first connecting portion 14 on the other side of the drive shaft 13, that is, the power mechanism 1 connects to two outer shell fittings 2 via the second connecting portion 15 on one side of the housing 11 and the first connecting portion 14 on the opposite side of the second connecting portion 15, and the power mechanism 1 is encased by the two outer shell fittings 2 to form a pet toy 10 in the shape of the outer shell fittings 2. The drive assembly 12 outputs power to the drive shaft 13. A first connecting part 14 at one end of the drive shaft 13 is connected to a housing accessory 2, while a second connecting part 15 of the housing 11 is not connected to another housing accessory 2. This means that power is transmitted to one housing accessory 2 while the other is not, causing the pet toy 10 to rotate unilaterally, thus attracting pets to interact and play. By connecting different housing accessories 2 through a single power mechanism 1, the pet toy 10 can present different appearances and movements, enriching its playability and adapting to various scenarios of playing with pets.

[0032] Understandably, referring to Figure 1 , 2 3. The outer surfaces of opposite sides of the housing 11 are provided with holes for the drive shaft 13 to pass through and extend out of the housing 11. (See reference 3) Figure 4 and 7When the power mechanism 1 is covered by the two housing accessories 2, the drive shaft 13 is not exposed, which also reduces the risk of pet hair getting caught and causing the pet toy 10 to move.

[0033] Understandably, a transmission connection refers to a connection method that effectively transmits the torque or rotational speed of the drive shaft 13 to the housing accessory 2 when the pet toy 10 is in operation. A non-transmission connection refers to a connection method in which the housing accessory 2 does not move with the drive shaft 13 and does not bear the output torque of the drive shaft 13 when the pet toy 10 is assembled and in normal operation. The clearance 111 refers to the gap located between the first connecting part 14 and the second connecting part 15 on the same side to avoid interfering with the assembly and operation of the pet toy 10.

[0034] Reference Figure 1 and 2 In at least one embodiment of the present invention, the first connecting part 14 includes an anti-rotation part 141 and a positioning part 142. The anti-rotation part 141 is arranged axially along the transmission shaft 13, and the positioning part 142 is arranged circumferentially along the transmission shaft 13.

[0035] Specifically, the anti-rotation part 141, which is axially arranged along the drive shaft 13, can be axially engaged with the outer casing part 2 to restrict the relative circumferential movement of the outer casing part 2; the positioning part 142, which is circumferentially arranged along the drive shaft 13, can be circumferentially engaged with the outer casing part 2 to restrict the relative axial movement of the outer casing part 2. Thus, through the first connecting parts 14 at both ends of the drive shaft 13, the outer casing part 2 is relatively fixed at both ends of the drive shaft 13, thereby realizing that the drive shaft 13 drives the outer casing part 2 to move, that is, realizing the rolling or movement of the pet toy 10.

[0036] Reference Figure 2 and 5 In at least one embodiment of the present invention, the second connecting part 15 includes a snap-fit ​​part 151 and a guide part 152, which are spaced apart around the drive shaft 13 and disposed on the outer surface of the housing 11.

[0037] Specifically, the guide portion 152 can guide the outer shell accessory 2 towards the snap-fit ​​portion 151, which can snap-fit ​​with the outer shell accessory 2. That is, the second connecting portion 15 performs a snap-fit ​​operation with the outer shell accessory 2 to fix the outer shell accessory 2 relative to the second connecting portion 15. The second connecting portion 15 on one side of the housing 11 snaps with one outer shell accessory 2, and the first connecting portion 14 on the other side of the housing 11 is drivenly connected to another outer shell accessory 2. That is, the first connecting portion 14 on the opposite side of the second connecting portion 15 is drivenly connected to another outer shell accessory 2, thereby forming a situation where one side of the outer shell accessory 2 is relatively fixedly connected to the power mechanism 1, and the other side of the outer shell accessory 2 is moved by the drive shaft 13, realizing the unilateral rotational movement of the pet toy 10.

[0038] Understandably, the snap-fit ​​part 151 and the guide part 152 are arranged around the drive shaft 13 at intervals, and the length of the second connecting part 15 is less than the length of the drive shaft 13 extending out of the outer side of the housing 11. That is, a clearance 111 is reserved for the second connecting part 15 and the first connecting part 14 on the same side, so that the power mechanism 1 can replace different outer shell accessories 2 through different connecting parts without affecting the assembly of different connecting parts, so as to realize different appearance shapes and movement states of the pet toy 10.

[0039] Reference Figure 1 In at least one embodiment of the present invention, the housing 11 is provided with a protrusion 16, the protrusion 16 protruding at least partially around the outer periphery of the housing 11, and the housing 11 is provided with a button 17, the button 17 being close to the protrusion 16 and protruding along the outer periphery of the housing 11.

[0040] Specifically, the protrusion 16 can be arranged around the outer surface of the center of the housing 11 and protrude outwards, or the protrusion 16 can be arranged partially around the outer periphery of the housing 11 and protrude outwards. Users can easily connect and cooperate with the outer casing accessory 2 through the protrusion 16 of the power mechanism 1. For example, when disassembling the outer casing accessory 2 from the power mechanism 1, the force point can be found on the protrusion 16 for disassembly, making the operation simpler and more convenient. At the same time, the protrusion 16 can prevent damage to the edges of the outer casing accessory 2 during assembly, ensuring the stability and reliability of the connection between the power mechanism 1 and the outer casing accessory 2.

[0041] Understandably, referring to Figure 4 , 7 12, 13. The outer casing 2 covers the power mechanism 1. The protrusion 16 is not covered by the outer casing 2, but the edge of the protrusion 16 is lower than the edge of the outer casing 2 so as not to hinder the movement of the outer casing 2. The button 17 is connected to the drive assembly 12. The button 17 is located near the protrusion 16 and protrudes along the outer periphery of the housing 11. Therefore, the button 17 is also not covered by the outer casing 2, so that the user can trigger the button 17 without disassembling the outer casing 2, so that the pet toy 10 can start, stop or switch functions.

[0042] Reference Figure 1 and 2 In at least one embodiment, the housing 11 is provided with a protrusion 16, which protrudes at least partially around the outer periphery of the housing 11, and the housing 11 is provided with a third connecting portion 18, which is close to the protrusion 16 and disposed on the outer surface of the housing 11.

[0043] Understandably, since the third connecting part 18 is located near the protrusion 16 on the outer surface of the housing 11, the third connecting part 18 is not covered by the outer shell accessory 2. This allows users to assemble and disassemble the support accessory 24 of the pet toy 10 without disassembling the outer shell accessory 2, thereby increasing the variety of shapes and movement states of the pet toy 10.

[0044] Reference Figure 1 and 3 In at least one embodiment, the housing 11 is provided with a protrusion 16, which protrudes at least partially around the outer periphery of the housing 11, and a light-emitting unit 19 is installed inside the housing 11, which is arranged to transmit light toward the protrusion 16.

[0045] Understandably, the light-emitting unit 19 is positioned towards the protrusion 16 to facilitate the emission of light by the light-emitting unit 19 without being blocked by the housing accessory 2. A hole or a transparent element 191 can be provided at the position of the protrusion 16 so that the light-emitting unit 19 can transmit light through the hole or through the transparent element 191.

[0046] In at least one embodiment, the housing 11 is provided with a protrusion 16, which partially surrounds the outer periphery of the housing 11 and protrudes outwards; the housing 11 is provided with a button 17, which is close to the protrusion 16 and protrudes outwards along the outer periphery of the housing 11; the housing 11 is provided with a third connecting portion 18, which is close to the protrusion 16 and disposed on the outer surface of the housing 11; and a light-emitting unit 19 is installed inside the housing 11, which is light-transmitting towards the protrusion 16.

[0047] Specifically, refer to Figure 1 , 2 The light-emitting unit 19, button 17, and third connecting part 18 can be arranged close to the protrusion 16 in the following order: button 17, third connecting part 18, and light-emitting unit 19. The button 17 is positioned close to the third connecting part 18 to ensure that it is not accidentally pressed when the pet toy 10 is in motion, provided the support accessory 24 is connected to the third connecting part 18. The light-emitting unit 19 is positioned close to the button 17 to make it easier to distinguish the light color and understand the current functional mode of the power mechanism 1. Understandably, the protrusion 16 can be arranged around the outer surface of the housing 11, but depending on the function and play requirements of the pet toy 10, the protrusion 16 around the outer surface of the housing 11 can accommodate the button 17, the third connecting part 18, and the light-emitting unit 19.

[0048] Reference Figure 2 In at least one embodiment of the present invention, the third connecting part 18 includes a plug-in part 181 and a limiting part 182. The plug-in part 181 is disposed on the outer surface of the housing 11, and the limiting part 182 is located at the edge of the plug-in part 181.

[0049] Specifically, the insertion part 181 facilitates the location and connection of the support accessory 24, while the limiting part 182 restricts the movement of the support accessory 24, ensuring that the support accessory 24 is relatively fixed on the power mechanism 1. When the power mechanism 1 needs to be assembled with the outer shell accessory 2, the power mechanism 1 is then connected to the support accessory 24 via the third connecting part 18, thus providing another form of pet toy 10 and giving pets more play experiences. More specifically, the depth of the insertion part 181 is radially set towards the shell 11 to facilitate the insertion of the third connecting part 18 into the support accessory 24.

[0050] Reference Figure 3 In at least one embodiment of the present invention, the drive assembly 12 includes a motor 121, an input gear 122 and an output gear 123. The input gear 122 is installed at the output end of the motor 121, and the output gear 123 is connected to the transmission shaft 13. The input gear 122 and the output gear 123 mesh and drive each other.

[0051] Specifically, the output end of the motor 121 drives the input gear 122 to rotate. Through the meshing transmission between the input gear 122 and the output gear 123, the output gear 123 transmits power to the transmission shaft 13. This method can achieve precise and stable power transmission.

[0052] Understandably, in order to optimize the driving efficiency of the power mechanism 1, the power mechanism 1 can be configured as a gearbox assembly containing multiple gears. The gearbox assembly also includes an input gear 122 and an output gear 123. The input gear 122 is transmitted to the output gear 123 through the meshing of multiple gears. The output end of the motor 121 is connected to the input gear 122, and the output gear 123 is connected to the transmission shaft 13. That is, the power output from the motor 121 is transmitted to the transmission shaft 13 through the gearbox assembly, which can precisely control the movement speed and force of the transmission shaft 13, so that the assembled pet toy 10 presents a more stable movement state.

[0053] Reference Figure 3 In at least one embodiment, the power mechanism 1 further includes a power supply component 3, which is located inside the housing 11 and connected to the drive assembly 12. The power supply component 3 is used to supply power to the drive assembly 12. Preferably, the power mechanism 1 further includes a charging port 31, which is located on the outer surface of the housing 11 and connected to the power supply component 3. The charging port 31 facilitates the user to charge the power supply component 3, reducing the need for disassembly and replacement of the power supply component 3.

[0054] Reference Figure 3 In at least one embodiment, the power mechanism 1 further includes a sound-emitting unit 4 located within the housing 11. The sound-emitting unit 4 emits sounds to attract a pet to approach the pet toy 10 for interaction and play. The sound-emitting unit 4 can be a buzzer, horn, or other sound-emitting component.

[0055] Reference Figure 5 and 8 A pet toy 10 according to an embodiment of the present invention includes a shell accessory 2 and the aforementioned power mechanism 1. The inner surface of the shell accessory 2 is provided with a fourth connecting part 25 or a fifth connecting part 26. Both inner surfaces of the shell accessories 2 are provided with a fourth connecting part 25, which is adapted to a first connecting part 14. The power mechanism 1 and the shell accessories 2 are detachably connected via the first connecting parts 14 at both ends of the drive shaft 13 and the fourth connecting parts 25 of the two shell accessories 2 to form a pet toy 10 in the shape of the shell accessory 2. Alternatively, one inner surface of the shell accessory 2 is provided with a fourth connecting part 25 and the inner surface of the shell accessory 2 is provided with a fifth connecting part 26. The fourth connecting part 25 is adapted to the first connecting part 14, and the fifth connecting part 26 is adapted to the second connecting part 15. The power mechanism 1 and the shell accessories 2 are detachably connected via the second connecting part 15 on one side of the shell 11 and the fifth connecting part 26 of the shell accessory 2, and the first connecting part 14 and the fourth connecting part 25 on the opposite side of the second connecting part 15 to form a pet toy 10 in the shape of the shell accessory 2.

[0056] Understandably, the fourth connecting portion 25 on the inner surface of the outer casing 2 is adapted to the first connecting portion 14 of the power mechanism 1, or the fifth connecting portion 26 on the inner surface of the outer casing 2 is adapted to the second connecting portion 15 of the power mechanism 1. Therefore, the two outer casings 2 can be detachably connected to the first connecting portions 14 at both ends of the drive shaft 13 of the power mechanism 1 and the two outer casings 2 with fourth connecting portions 25, so that the two outer casings 2 cover both sides of the power mechanism 1 and are combined to form a pet toy 10 with a double-sided drive outer casing 2 shape; or the two outer casings 2 can be detachably connected to the second connecting portion 15 on one side of the power mechanism 1 and the outer casing 2 with a fifth connecting portion 26, and the two outer casings 2 can be detachably connected to the first connecting portion 14 on the other side of the power mechanism 1 and the outer casing 2 with a fourth connecting portion 25, so that the two outer casings 2 cover both sides of the power mechanism 1 and are combined to form a pet toy 10 with a single-sided drive outer casing 2 shape. By connecting two shell accessories 2 in different ways through a single power mechanism 1, the pet toy 10 can present different appearances and movement states, overcoming the limitation of "one toy = one way to play" in the existing technology. This allows the pet toy 10 to produce differentiated movement forms according to different combinations of shell accessories 2, so as to attract pets at different growth stages and meet the pets' play needs.

[0057] Reference Figure 4 , 5In at least one embodiment of the present invention, a housing accessory 2 is a roller housing 21. The roller housing 21 is hollow hemispherical in shape. A fourth connecting part 25 is provided on the inner surface of the roller housing 21. The fourth connecting part 25 includes a shaft groove 251, an anti-rotation fitting part 252 and a positioning fitting part 253. The anti-rotation fitting part 252 is axially distributed along the inner wall of the shaft groove 251, and the positioning fitting part 253 is circumferentially distributed along the inner wall of the shaft groove 251.

[0058] Reference Figure 7 , 8 In at least one embodiment of the present invention, a housing accessory 2 is a rope-swing housing 22. The outer surface of the rope-swing housing 22 is connected to a first rope 221. The inner surface of the rope-swing housing 22 is provided with a fourth connecting part 25. The fourth connecting part 25 includes a shaft groove 251, an anti-rotation fitting part 252 and a positioning fitting part 253. The anti-rotation fitting part 252 is axially distributed along the inner wall of the shaft groove 251, and the positioning fitting part 253 is circumferentially distributed along the inner wall of the shaft groove 251.

[0059] Reference Figure 7 , 8 In at least one embodiment of the present invention, a housing accessory 2 is a counterweight housing 23, a counterweight 231 is installed inside the counterweight housing 23, a curved surface 232 is provided at the center of the outer surface of the counterweight housing 23, the counterweight 231 is disposed close to the curved surface 232, a fifth connecting part 26 is provided on the inner surface of the counterweight housing 23, the fifth connecting part 26 includes a snap-fit ​​part 261 and a guide fit part 262, the snap-fit ​​part 261 and the guide fit part 262 are spaced apart around the central axis of the counterweight housing 23.

[0060] Understandably, when the fourth connecting part 25 on the inner surface of the roller housing 21 is connected to the first connecting part 14 of the power mechanism 1, the shaft groove 251 facilitates the alignment of the transmission shaft 13. First, the anti-rotation fitting part 252, which is axially distributed along the inner wall of the shaft groove 251, engages with the anti-rotation part 141, which is axially arranged along the transmission shaft 13, thus restricting the relative circumferential movement of the roller housing 21 and the power mechanism 1. Then, the positioning fitting part 253, which is circumferentially distributed along the inner wall of the shaft groove 251, engages with the positioning part 142, which is circumferentially arranged along the transmission shaft 13, thus restricting the relative axial movement of the roller housing 21 and the power mechanism 1. Thus, the roller housing 21 is relatively fixed on one side of the power mechanism 1. The fourth connecting portion 25 of the two roller housings 21 is installed on the first connecting portion 14 at opposite ends of the drive shaft 13, so that the two roller housings 21 are fixed relative to each other on both sides of the power mechanism 1, so as to realize the transmission of power to the drive shaft 13 through the drive assembly 12. The drive shaft 13 drives the roller housings 21 to move, realizing the rolling or moving motion of the pet toy 10. Understandably, the roller housings 21 are hollow hemispherical in shape. The hollow design inside the roller housings 21 can well cover the power mechanism 1. Since a single roller housing 21 is hemispherical, the two roller housings 21 are spherical. When the drive shaft 13 transmits power to the roller housings 21, the spherical shape can roll more randomly, which is more in line with the pet's exploratory nature.

[0061] Preferably, refer to Figure 1 The positioning part 142 is located away from the housing 11 at the end of the drive shaft 13, as shown in the reference. Figure 9 The positioning and fitting part 253 is located near the bottom of the shaft groove 251. When the anti-rotation fitting part 252 of the roller housing 21 moves axially along the anti-rotation part 141, the drive shaft 13 can be connected to the roller housing 21 as much as possible until the positioning part 142 away from the housing 11 engages with the positioning and fitting part 253 near the bottom of the groove, then the roller housing 21 is relatively fixed on one side of the drive shaft 13.

[0062] Understandably, when the fifth connecting portion 26 on the inner surface of the counterweight housing 23 is connected to the second connecting portion 15 on one side of the power mechanism 1, since the snap-fit ​​portion 261 and the guide portion 262 of the fifth connecting portion 26 are spaced apart around the central axis of the counterweight housing 23, and the snap-fit ​​portion 151 and the guide portion 152 of the second connecting portion 15 are spaced apart around the transmission shaft 13, the snap-fit ​​portion 151 is guided towards the snap-fit ​​portion 261 for snap-fit ​​connection through the adaptation of the guide portion 152 and the guide portion 262, and the counterweight housing 23 is relatively fixed on one side of the power mechanism 1. The first connecting part 14 on the other side of the power mechanism 1 is connected to the fourth connecting part 25 on the inner surface of the rope-swing housing 22. The shaft groove 251 facilitates the alignment of the drive shaft 13. First, the anti-rotation fitting part 252, which is axially distributed along the inner wall of the shaft groove 251, engages with the anti-rotation part 141, which is axially arranged along the drive shaft 13, thus restricting the relative circumferential movement of the rope-swing housing 22 and the power mechanism 1. Then, the positioning fitting part 253, which is circumferentially distributed along the inner wall of the shaft groove 251, engages with the positioning part 142, which is circumferentially arranged along the drive shaft 13, thus restricting the relative axial movement of the rope-swing housing 22 and the power mechanism 1. Thus, the rope-swing housing 22 is relatively fixed on the other side of the power mechanism 1. The counterweight housing 23 is mounted on the power mechanism 1 by the fifth connecting part 26 of the counterweight housing 23, the second connecting part 15 is mounted on one side of the power mechanism 1, and the fourth connecting part 25 is mounted on the first connecting part 14 on the other side of the power mechanism 1. This makes the counterweight housing 23 and the rope housing 22 relatively fixed on both sides of the power mechanism 1, so that the power can be transmitted to the drive shaft 13 through the drive assembly 12. The drive shaft 13 drives the rope housing 22 to move. Since the counterweight housing 23 is not connected to the drive shaft 13, the counterweight housing 23 is relatively fixed on one side. Affected by the center of gravity of the counterweight housing 23, the pet toy 10 exhibits a unilateral rotating rope swinging motion.

[0063] Specifically, the structures of the anti-rotation part 141 and the anti-rotation mating part 252 include, but are not limited to, structures where a key and keyway, a groove and a protrusion, a snap ring groove and a snap ring cooperate to restrict circumferential movement. The structures of the positioning part 142 and the positioning mating part 253 include, but are not limited to, structures where a key and keyway, a groove and a protrusion, a snap ring groove and a snap ring cooperate to restrict axial movement. The structures of the snap-fit ​​part 151 and the snap-fit ​​mating part 261 include, but are not limited to, structures where a hook and a latch, a cantilever hook and a groove cooperate to form a snap-fit ​​structure. The structures of the guide part 152 and the guide mating part 262 include, but are not limited to, structures where a slider and a groove, a guide post and a guide sleeve cooperate to form a guiding structure.

[0064] In at least one embodiment, reference Figure 1 and 9The anti-rotation part 141 and the anti-rotation mating part 252 are specifically structured as a keyway and a key, while the positioning part 142 and the positioning mating part 253 are specifically structured as an annular groove and an annular protrusion. In at least one embodiment, referring to... Figure 2 and 10 The specific structure of the snap-fit ​​part 151 and the snap-fit ​​mating part 261 is a snap hook and a fastener, and the specific structure of the guide part 152 and the guide mating part 262 is a T-shaped slider and a T-shaped groove.

[0065] It should be noted that, referring to Figure 11 With the cooperation of the curved surface 232 on the outer side of the counterweight shell 23 and the internal counterweight 231, the pet toy 10 with the counterweight shell 23 installed has a "roly-poly" property, that is, under the influence of the counterweight 231, the pet toy 10 rotates in one direction and then returns to a stationary state. The length of the second connecting part 15 is less than the length of the drive shaft 13 extending out of the shell 11, that is, a clearance gap 111 is reserved between the second connecting part 15 and the first connecting part 14. When the second connecting part 15 is connected to the fifth connecting part 26, the counterweight shell 23 with the fifth connecting part 26 has space to accommodate the longer drive shaft 13, so that the drive shaft 13 does not contact the counterweight shell 23, that is, the drive shaft 13 will transmit power but will not drive the counterweight shell 23. (Refer to...) Figure 7 The outer surface of the swing rope housing 22 is connected to a first rope 221. The swing rope housing 22 has an inclined channel 223 and a first through hole 222. The diameter of the first through hole 222 matches the diameter of the first rope 221. A knot is tied at one end of the first rope 221 to accommodate it in the channel 223 and confine it to the first through hole 222, making it difficult for the first rope 221 to be pulled out during pet interaction. The swinging motion of the first rope 221 can stimulate the pet's senses, arousing the pet's curiosity and interaction. The inclined channel 223 tilts the first rope 221, increasing the randomness of the swing rope housing 22 being driven by the drive shaft 13, which better satisfies the pet's exploratory nature and continuously attracts the pet to interact and play. The counterweight housing 23 and the swing rope housing 22 are hollow, meaning that space is left to better cover the outside of the power mechanism 1.

[0066] Reference Figure 4 , 5 In at least one embodiment of the present invention, the housing 11 is provided with a protrusion 16, which protrudes at least partially around the outer periphery of the housing 11; wherein, when the two outer casing fittings 2 are connected to the two sides of the power mechanism 1, the protrusion 16 is not covered by the two outer casing fittings 2, and the edge of the protrusion 16 is lower than the edge of the outer casing fitting 2.

[0067] Specifically, the protrusion 16 is not covered by the two outer shell fittings 2, that is, the protrusion 16 is exposed on the outer surface of the pet toy 10. The edge of the protrusion 16 is lower than the edge of the outer shell fitting 2. Therefore, the edge of the outer shell fitting 2 contacts the contact surface first, while the edge of the protrusion 16 is suspended in the air, which does not hinder the movement of the outer shell fitting 2.

[0068] Reference Figure 4 , 5 In at least one embodiment of the present invention, the pet toy 10 further includes a support accessory 24, which includes a support end 241 and a sixth connecting part 27, with the support end 241 and the sixth connecting part 27 being disposed opposite to each other; the outer surface of the housing 11 is provided with a third connecting part 18, wherein the sixth connecting part 27 is adapted to the third connecting part 18.

[0069] Specifically, the sixth connecting portion 27 of the support accessory 24 is adapted to connect with the third connecting portion 18 of the housing 11. Since the support end 241 is positioned opposite to the sixth connecting portion 27, the support end 241 is away from the housing 11 and contacts the contact surface. When the pet toy 10 moves, the support end 241 can provide a support point, thus changing the pet toy 10 from a state of irregular rolling or moving to a state of moving forward or backward in one direction, enriching the ways to play with the pet toy 10 and making it more attractive for pets to play and interact. Understandably, the contact surface is a surface such as a cement floor or a wooden floor where the pet toy 10 can move.

[0070] Reference Figure 6 In at least one embodiment of the present invention, the sixth connecting part 27 includes a plug-in mating part 271 and a limiting mating part 272, with the limiting mating part 272 located on the outer surface of the plug-in mating part 271.

[0071] Specifically, the third connecting part 18 includes a plug-in part 181 on the outer surface of the housing 11 and a limiting part 182 located at the edge of the plug-in part 181. When the sixth connecting part 27 is connected to the third connecting part 18, the plug-in mating part 271 is aligned with the plug-in part 181 and moves closer to the plug-in part 181 for plugging. When the plug-in mating part 271 is inserted in the plugging direction, the limiting mating part 272 gradually moves closer to the limiting part 182 and is locked by the limiting part 182, thus completing the assembly of the sixth connecting part 27 and the third connecting part 18. By connecting the support accessory 24 to the power mechanism 1, the pet toy 10 has a support point and can move in one direction. For example, when the two roller shells 21 are fixed relative to each other on both sides of the power mechanism 1, and the support accessory 24 is assembled, the drive shaft 13 drives the roller shells 21 to move. The support accessory 24 is equivalent to the support point of the contact surface, so as to support the roller to move in one direction, enriching the play of the pet toy 10, and is also suitable for active pets to chase and play.

[0072] Reference Figure 12In at least one embodiment of the present invention, the support accessory 24 is equipped with a second rope 242, and the support accessory 24 is provided with a second through hole 243, through which the second rope 242 is installed on the support accessory 24.

[0073] Specifically, one end of the second rope 242 is knotted or a limiting member is provided at one end. By knotting one end of the second rope 242 to limit it to the second through hole 243, or by providing a limiting member at one end of the second rope 242 to limit it to the second through hole 243, the second rope 242 is not easily pulled out of the support accessory 24 during pet interaction. When the second rope 242 is installed on the support accessory 24, and the support end 241 contacts and supports the contact surface, the second rope 242 moves forward and swings under the movement of the roller housing 21, like an animal's tail, to attract the pet to chase the second rope 242.

[0074] Preferably, there are two support ends 241, which are symmetrically distributed. The second rope 242 is installed on the axis of symmetry so that the pet toy 10 is balanced when it moves in one direction, making the pet toy 10 move more smoothly.

[0075] Understandably, referring to Figure 4 , 7 Users can freely combine the fourth connecting part 25 of the roller shell 21, the fourth connecting part 25 of the rope shell 22, the fifth connecting part 26 of the counterweight shell 23 with the first connecting part 14 and the second connecting part 15 of the power mechanism 1 to create pet toys 10 with different shapes. Users can also add more shapes of pet toys 10 by connecting the sixth connecting part 27 of the support accessory 24 with the third connecting part 18 of the power mechanism 1 to enrich the play of pet toys 10 and continuously attract the pet's curiosity.

[0076] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
