[Solution] The system comprises a central shaft 1 and a first rotating wheel 3 and a second rotating wheel 4 located on either side of the central shaft. The central shaft controls the scrolling motion of the first and second rotating wheels using a motor. Support feet 10 are distributed around the central shaft to provide the force acting between the central shaft and the ground during motor operation, generating gripping force on the first and second rotating wheels. With this configuration, when a dog bites one wheel, torque is generated in the other wheel, but the direction of that torque is the same as the direction of rotation of the wheel, and no lateral torsional force is generated, resulting in superior durability.

Description

Technical Field

[0001] This utility model relates to the technical field of pet toys, and particularly to electronic toys for pets.

Background Art

[0002] An electronic toy for pets is an electronic toy for pets to play with, and is generally used for dogs and cats to chase and bite and play.

[0003] In the prior art, an electronic toy for pets is generally spherical, and in order to attract the attention of pets, it has a light-emitting member or a sound-emitting member inside. There are also toy cars that attract the attention of pets by running on the ground.

[0004] The problem with the prior art is that in the case of a toy car, parts such as wheels and the car body cannot withstand the biting of dogs and are extremely easy to break. Even if the outside is covered with a bite-resistant material such as rubber, the effect is still not ideal, and the connecting part of the wheel is still easy to break. On the other hand, moving an object is an important function for playing autonomously with pets.

[0005] In the AI era, the intelligentization of electronic toys for pets has already been realized. From the perspective of intelligentization, even when the owner is absent, it is fully possible for the electronic toy to accompany the pet throughout the day. However, the above problems, that is, "objects that can move lack durability, and objects with durability cannot move", become obstacles and are problems.

Summary of the Invention

Problems to be Solved by the Invention

[0006] An object of this utility model is to provide an electronic toy for pets for improving the durability of an electronic toy for pets having a movement function.

Means for Solving the Problems

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an electronic toy for pets comprising a central shaft and a first rotating wheel and a second rotating wheel located on both sides of the central shaft, wherein the central shaft controls the scrolling motion of the first and second rotating wheels by a motor, and support feet are distributed around the central shaft to provide the force acting between the central shaft and the ground during motor operation, thereby generating a gripping force on the first and second rotating wheels.

[0008] In this configuration, the rotation of the two coaxial wheels means that when a dog bites one wheel, torque is generated in the other wheel, but the direction of that torque is the same as the direction of the wheel's rotation, and no lateral torsional force is generated, resulting in superior durability. Furthermore, the support feet overcome the technical obstacle that, with only two coaxial wheels, only internal forces exist and no interaction force with the bottom surface can be formed.

[0009] Objects that move via wheels can have their rotation restricted by having two wheels, like a bicycle, four wheels, like a car, or a wheel in the middle, like a tricycle. However, pet toys with a wheel in the middle or four wheels have an extremely high rate of breakage when pets chase or bite them, and problems such as tires falling off or the body of the small vehicle being damaged are likely to occur. In the case of a rotating system with two wheels, if a dog bites one wheel, the rotation of the other wheel will hit the dog's mouth and create a lateral twisting force, making the wheel prone to coming off during play and resulting in insufficient strength.

[0010] Furthermore, the number of support feet is two or more, and the multiple support feet are evenly distributed on the central shaft, and each support foot comprises a contact portion that contacts the ground, a vertex portion that is the highest point, and a transition portion that smoothly transitions between the contact portion, the vertex portion, and the central shaft. The common tangent is defined as the tangent to the outer edge of the central shaft and the common tangent to the outer edge of the support foot. This common tangent contacts the support foot at the contact point, which is arc-shaped. The perpendicular line to the common tangent at this point is defined as the central perpendicular. The straight line connecting the contact point and the center of the motor's output shaft is defined as the torque line, and the angle between the torque line and the common tangent is acute.

[0011] Furthermore, the curvature of the contact portion is smaller than the curvature of the corresponding arc of the central shaft.

[0012] Furthermore, the angle between the torque line and the common tangent is 70 to 80°.

[0013] Furthermore, the central shaft body comprises a central shaft plate and a shaft ring fixed in an annular shape around the central shaft plate, the outer surface of the shaft ring is covered and fixed to the central shaft wall, and the support feet are integrally connected to the central shaft wall.

[0014] Furthermore, the outer edge of the support foot is arc-shaped, and the circle on which it is located is concentric with the outer circumference of the central shaft.

[0015] Furthermore, one of the multiple support legs is a connecting ring, the height of which is greater than that of the other support legs, and the connecting ring is an annular shape with a hollow middle section, for connecting to other toys or accessories.

[0016] Furthermore, a main body bracket is fixed vertically on the central shaft plate, and the motor comprises a first motor and a second motor provided within the main body bracket. The first motor and the second motor are used to drive the first and second rotating wheels, respectively, and are located inside the first and second rotating wheels, respectively.

[0017] Furthermore, the first rotating wheel comprises a first inner shell and a first outer shell covering the outside of the first inner shell, the first outer shell being made of natural rubber.

[0018] Furthermore, a fixing structure is provided between the body of the first motor and the body bracket, the fixing structure includes a motor fixing cover that covers the body of the first motor, the motor fixing cover is perpendicular to the first motor and located on one side closer to the output shaft of the first motor, the motor fixing cover is provided with a through hole for the motor's output shaft to pass through, at least two fixing columns protrude vertically from one end of the outer shell of the motor body facing the motor fixing cover, the motor fixing cover is provided with a restricting hole for the fixing columns to pass through, fixing holes are provided vertically around the motor fixing cover, bolts are provided that pass through the fixing holes and are screw-connected to the side wall of the body bracket, the body bracket surrounds the periphery of the first motor and the second motor and has an open end, and the side wall of the end of the body bracket is screw-connected to the bolt.

[0019] Furthermore, a connecting structure is provided between the output shaft of the first motor and the first inner shell, the connecting structure includes an engagement groove located at the far end of the output shaft of the first motor, the engagement groove is formed by cutting out a circular notch along the side surface of the output shaft of the first motor, the first inner shell is provided with an insertion hole into which the output shaft of the first motor is inserted, part of the engagement groove is located inside the insertion hole and the other part is located outside the insertion hole, the connecting structure further includes a snap ring fitted into the engagement groove, the snap ring so that one side abuts against the inner wall of the engagement groove and the other side abuts against the outer wall of the first inner shell, thereby allowing the first inner shell to be brought into close contact in the direction of the central axis, and the output shaft is a cylindrical body with a rectangular cross-section or a corner portion.

[0020] Furthermore, a circuit board coupled to the first motor and the second motor is fixed to the central shaft plate, and the circuit board has control units that control the forward / reverse rotation and starting / stopping of the two motors, respectively.

[0021] Furthermore, a recording module and a playback module for recording and playing back audio are further coupled to the circuit board.

[0022] Furthermore, a radar module fixed to the central shaft body is further coupled to the circuit board. The radar module is used to detect moving objects in the surroundings and automatically start up, and enter the standby state when moving objects are detected within a preset time.

Advantages of the Invention

[0023] In short, compared with the prior art, the present utility model has the following beneficial effects.

[0024] The present utility model effectively improves the durability of the toy through the design of its unique support feet. Depending on the shape and distribution method of the support feet, it ensures the stability of the central shaft body during movement, disperses the acting force generated when the pet bites, and can reduce the risk of damage to components such as wheels and the vehicle body. The plurality of support feet are evenly distributed on the central shaft body, and due to their specific shape, when the pet interacts with the toy, the force can be transmitted more evenly, avoiding damage caused by excessive local force reception.

[0025] Also, through the curvature design at the contact point of the support feet and the range of the angle formed by the torque line and the common tangent line, the mechanical performance of the toy is further optimized. With such a design, the toy can better adapt to the frictional force with the ground and the acting force from the pet during the rotation process, improving the grip force and the stability of movement. At the same time, within an appropriate angle range, the possibility of deformation or damage when the toy is subjected to an external force is also reduced.

[0026] Regarding the connection structure, both the fixing structure between the motor and the main body bracket and the connection structure between the motor output shaft and the inner shell of the rotating wheel are carefully designed. The fixing structure ensures that the motor is firmly attached inside the toy, preventing loosening due to vibration or collision during movement. The connection structure ensures efficient transmission of power and allows the rotating wheel to be adjusted within a certain range to cope with different movement states and the pet's playing methods.

[0027] Furthermore, the installation of the control unit, recording module, playback module, and radar module on the circuit board adds additional functions and interest to the toy. The control unit can flexibly control the forward and reverse rotation and start / stop of the two motors, and by imitating various movement trajectories for the toy, it increases the fun of the pet's play. The recording module and playback module can record and play back voices, further attracting the pet's attention. The radar module realizes the intelligence of the toy, and can automatically start or enter the standby state according to changes in the surrounding environment, improving the usage efficiency and power-saving performance of the toy.

[0028] In short, the electronic toy for pets of this utility model has been significantly improved in terms of durability and functionality, better meets the needs of pets and their owners, and can bring a richer and more interesting play experience to the pets.

Modes for Carrying Out the Invention

[0030] The following describes the technical solutions in the embodiments of this utility model with reference to the drawings of the embodiments. Of course, the embodiments described are only a subset of the embodiments of this utility model, not all of them. All other embodiments obtained by a person skilled in the art, assuming that no creative work has been done by a person skilled in the art using the embodiments of this utility model, are all within the scope of the claims of this utility model.

[0031] Example 1: Referring to Figure 1, the pet electronic toy comprises a central shaft 1, a first rotating wheel 3, and a second rotating wheel 4. Both the first rotating wheel 3 and the second rotating wheel 4 rotate relative to the central shaft 1, and the central shaft 1 is equipped with motors for driving and rotating the first rotating wheel 3 and the second rotating wheel 4, respectively.

[0032] The relative rotation between the first rotating wheel 3 and the second rotating wheel 4 and the central shaft 1 imparts motor capabilities to the pet electronic toy, and it is possible to realize turning movements of the pet electronic toy according to the difference in the rotation direction and rotation rhythm of the two rotating wheels. For example, by making the rotation speed of the first rotating wheel 3 greater than that of the second rotating wheel 4, it is possible to realize a turning movement toward the first rotating wheel 3.

[0033] In this embodiment, the central shaft 1 is located between the first rotating wheel 3 and the second rotating wheel 4, and has an annular shape. The motor body and output shaft are fixed to the central shaft 1 and the rotating wheel, respectively, and the forces acting on the relative motion of the two are realized.

[0034] However, with such an annular shape, when the motor starts, it may spin freely in place and be unable to move forward. The central shaft 1 needs to have some support between itself and the ground and form a reaction force to the motor's power so that the motor's power causes the first rotating wheel 3 and the second rotating wheel 4 to move relative to the ground. This is similar to the role played by the middle wheel of a tricycle, but since the pet electronic toy in this embodiment only has two wheels, it cannot form a support force between itself and the ground. To solve this problem, support legs 10 are integrally connected to the outer circumference of the central shaft 1.

[0035] In this embodiment, three support feet 10 are provided, evenly distributed on the outside of the central shaft, and the height of the support feet is higher than the outer edges of the first rotating wheel 3 and the second rotating wheel 4.

[0036] In this utility model, one of the three support legs 10 is used to connect a rope, and the dimensions of the remaining two connection points are as follows. Length: 19.24mm, Width: 12.62mm, Height: 5.71mm

[0037] The dimensions of the third support leg 10, also known as the connecting ring 14, are as follows: Length: 25.22mm, Width: 8.97mm, Height: 15.29mm

[0038] According to the above dimensions, good support capacity can be achieved, slippage during use is less likely, and a good support effect can be provided. After starting, when the support point touches the ground, the first rotating wheel 3 and the second rotating wheel 4 have good grip force, and the above size also results in low frictional resistance against the ground.

[0039] Referring to Figure 3, the support foot comprises the farthest end from the central shaft 1, a contact portion 80 that contacts the ground when the product is placed on the ground, and a transition portion for smooth transition. The shape of the outer edge of the support foot 10 satisfies the following rules: the common tangent line 84 is the tangent line between the outer edge of the central shaft 1 and the outer edge of the support foot 10; the point of contact between the common tangent line 84 and the support foot 10 is at the contact portion 80, which is arc-shaped; the perpendicular line at the point of contact between the central shaft 1 and the common tangent line 84 (a straight line connecting the center of the transition portion and the point of contact, in which case the perpendicular line should be perpendicular to the common tangent line 84) is named the central perpendicular line 85; the perpendicular line at the point of contact between the central shaft 1 and the common tangent line 84 is named the principal perpendicular line 83; and the point of contact between the contact portion 80 and the common tangent line 84 is the axis of the motor output shaft. The straight line connecting the center forms a torque, which is named the torque line 82. The angle between the torque line 82 and the common tangent 84 is acute. Thus, when the motor starts, the torque at the central shaft 1 is greater than the torque at the first rotating wheel 3 and the second rotating wheel 4, providing greater support. Furthermore, when the motor's horsepower increases, or when the resistance at the support point is insufficient to cause it to exceed the support point due to inertia, the support point undergoes a "climbing" process, meaning the torque increases as it climbs. In this way, the support point can be made more stable. In this embodiment, the angle between the torque line 82 and the common tangent 84 is 75°, and the angle between the torque line 82 and the central perpendicular 85 is 15°. The angle between the torque line 82 and the main perpendicular 83 is 28°. In other embodiments, the above angles may vary within the range of 10 to 20°.

[0040] The arc curvature at the point of contact of the support foot is smaller than the corresponding arc curvature of the central shaft 1.

[0041] In this embodiment, the highest point / farthest end of the support leg 10, i.e., the vertex as the outer edge of the support leg 10, is arc-shaped, and the circle on which it is located is concentric with the outer circumference of the central shaft body 1. In this way, the height of the support leg 10 can be minimized and its sharpness minimized while maintaining the same support effect. This maintains overall harmony and makes it difficult for pets to get it into their mouths when they chew on it.

[0042] The remaining portion of the outer edge curve of the support leg 10 transitions smoothly, that is, it smoothly connects with the central shaft 1 at the common contact point, and the transition between the common contact point and the vertex is also smooth.

[0043] To obtain more appropriate dimensions for the support legs 10, multiple dimensional experiments were conducted as follows, and appropriate conclusions were reached.

[0044] Comparative Example 1: The "length, width, and height" of the three support legs 10 are limited as follows. Support leg 10: Length 22.5mm, width 12.62mm, height 6.36mm Support leg 10: Length 22.5mm, width 12.62mm, height 6.36mm Support leg 10 (connecting ring 14): Length 25.22 mm, width 15.29 mm, height 8.97 mm

[0045] The entire transition is smooth, and no local curve processing is performed.

[0046] In this comparative example, the support point is relatively high, allowing for a good support point. However, multiple experiments revealed that the resistance is high, causing the support point to lift due to the force applied during use. This temporarily separates the rotating wheel from the ground, weakening the grip force during movement.

[0047] Comparative Example 2: The "length, width, and height" of the three support legs 10 are limited as follows. Support leg 10: Length 28.34 mm, width 12.62 mm, height 7.39 mm Support leg 10: Length 28.34 mm, width 12.62 mm, height 7.39 mm Support leg 10 (connecting ring 14): Length 25.22 mm, width 15.29 mm, height 8.97 mm

[0048] The entire transition is smooth, and no local curve processing is performed.

[0049] Due to the slip phenomenon in the previous experiment, the inventor mistakenly believed that the height of the support foot 10 was insufficient, resulting in insufficient support force. In this comparative example, the inventor also mistakenly believed that a higher support point would provide better support. However, after multiple experiments, it was found that the slip situation worsened further, and the support point frequently lifted due to the applied force during the motion, causing the rotating wheel to temporarily detach from the ground, resulting in extremely weak grip force during the motion.

[0050] Comparative Example 3, Comparative Example 2: The "length, width, and height" of the three support legs 10 are limited as follows. Support leg 10: Length 14.87mm, width 12.62mm, height 4.24mm Support leg 10: Length 14.87mm, width 12.62mm, height 4.24mm Support leg 10 (connecting ring 14): Length 25.22 mm, width 15.29 mm, height 8.97 mm

[0051] The entire transition is smooth, and no local curve processing is performed.

[0052] In this comparative experiment, while the slip phenomenon was clearly reduced, scrolling occurred frequently. The central shaft 1 and the rotating wheel rotated simultaneously, resulting in many instances of free-spinning in place, making it impossible to complete corresponding forward, backward, and turning movements.

[0053] Comparative Example 4: The "length, width, and height" of the three support legs 10 are limited as follows. Support leg 10: Length 19.24mm, width 12.62mm, height 5.71mm Support leg 10: Length 19.24mm, width 12.62mm, height 5.71mm Support leg 10 (connecting ring 14): Length 25.22 mm, width 15.29 mm, height 8.97 mm

[0054] The entire transition is smooth, and no local curve processing is performed.

[0055] In this comparative experiment, slippage and scrolling occurred alternately, and while it operated normally in most situations, slippage and in-place scrolling still occurred frequently.

[0056] Comparative Example 5 (Solution Adopted): Based on Comparative Example 4, the curve of the support leg 10 is modified so that the angle between the torque line 82 and the common tangent line is acute, that is, so that the torque line 82 is located inside the central perpendicular line 85.

[0057] The "length, width, and height" of the three support legs 10 are limited as follows: Support leg 10: Length 19.24mm, width 12.62mm, height 5.71mm Support leg 10: Length 19.24mm, width 12.62mm, height 5.71mm Support leg 10 (connecting ring 14): Length 25.22 mm, width 15.29 mm, height 8.97 mm

[0058] In this experiment, slippage was almost nonexistent. Even when slippage occurred on ground with specific frictional forces, the slip duration was extremely short. Furthermore, because the contact point between the support foot 10 and the ground is arc-shaped, the frictional force is relatively small, and no rotational movement occurred during the motion.

[0059] Referring to Figure 2, which is an internal structure diagram, the internal structure is equipped with a main body bracket 2, which is fixed to the central shaft 1, and a first motor 32 for controlling the first rotating wheel 3 and a second motor 42 for controlling the second rotating wheel 4 are fixed inside the main body bracket 2, and relative motion is achieved by fixing the two motors and the central shaft 1 with the main body bracket 2 and fixing the output terminals of the two motors to the rotating wheels.

[0060] A fixing structure 5 is provided between the first motor 32 and the first rotating wheel 3, and between the second motor 42 and the second rotating wheel 4. Since the two fixing structures are identical, the fixing structure of the first motor 32 will be described as an example. The first motor 32 is equipped with a motor fixing cover 50 on the main body 320. The motor fixing cover 50 is perpendicular to the first motor 32 and is located at one end on the side closer to the motor output shaft. The motor fixing cover 50 has a through hole for the output shaft to pass through so as not to obstruct the output of the motor output shaft. Two fixing pillars protrude from one end of the outer shell of the motor body facing the motor fixing cover 50. The corresponding motor fixing cover 50 is provided with a limiting hole 501 for these pillars to pass through, thereby limiting the circumferential rotation of the motor. Fixing holes are formed vertically near the periphery of the motor fixing cover 50. Fixing bolts 52 are inserted through the fixing holes, and after the fixing bolts 52 are inserted through the fixing holes, they are screw-connected to the side wall of the main body bracket 2.

[0061] In this way, the motor and the main body bracket can be fixed together, and after the main body bracket 2 is fixed to the central shaft 1, the motor is fixed to the central shaft, and when the output end of the motor drives the first rotating wheel 3 and the second rotating wheel 4, relative motion with the central shaft 1 can be formed.

[0062] The central shaft body 1 comprises an annular shaft ring 11 and a central shaft plate fixed to its circular surface. The main body bracket 2 is fixed perpendicularly to the central shaft plate, and the connecting ring 14 is fixed perpendicularly to the outer wall of the shaft ring 11. The outer wall of the shaft ring 11 is covered by the central shaft wall 13, which is an outer shell for covering the central shaft plate 12. Of the three support feet, the remaining two support feet 10 are integrally connected to the central shaft wall 13, and the connecting ring 14 penetrates the central shaft wall 13 from the shaft ring and protrudes to the outside of the central shaft wall 13.

[0063] The main body bracket 2 is coupled with the first motor 32 and the second motor, and a circuit board for controlling the switches, rotation speed, and forward / reverse rotation direction of the first motor 32 and the second motor 42 is fixed to it.

[0064] Therefore, the rotation patterns of the two motors give the pet electronic toy the following eight types of motion patterns.

[0065] (1) Left wheel forward, right wheel stationary; (2) Left wheel backward, right wheel stationary; (3) Right wheel forward, left wheel stationary; (4) Right wheel backward, left wheel stationary; (5) Left wheel forward, right wheel backward; (6) Left wheel backward, right wheel forward; (7) Left wheel and right wheel simultaneously forward; (8) Left wheel and right wheel backward simultaneously.

[0066] The left wheel and right wheel mentioned above should be understood to refer to either the first rotating wheel 3 or the second rotating wheel. When the left wheel corresponds to the first rotating wheel 3, the right wheel corresponds to the second rotating wheel, and conversely, when the right wheel corresponds to the first rotating wheel 3, the left wheel corresponds to the second rotating wheel 4.

[0067] The circuit board contains a main control chip that randomly combines the eight types of movement patterns mentioned above and automatically switches between them every five seconds, providing dogs with a varied and unpredictable interactive experience that enhances the enjoyment of playtime for pets.

[0068] Referring to Figures 2 and 3, the first rotating wheel 3 comprises a first inner shell 31 and a first outer shell 30. The first inner shell is fixedly connected to the first outer shell 30 and is also fixed to the output terminal of the first motor 32. A connection structure is provided between the first motor and the first inner shell 31. A similar connection structure 6 exists between the second motor 42 and the second inner shell 41, and both are the same. The connection structure 6 in the first motor 32 will be explained as an example.

[0069] The connection structure 6 includes an engagement groove 60 located at the far end of the output shaft 321 of the first motor 32. The engagement groove 60 is formed circumferentially along the side surface of the output shaft of the first motor 32. The first inner shell 31 has an insertion hole into which the output shaft 321 of the first motor 32 is inserted. The engagement groove 60 is partially located inside the insertion hole and partially located outside the insertion hole. The connection structure further includes a snap ring fitted into the engagement groove 60. The snap ring causes the first inner shell 31 to be tightly attached in the axial direction by having one side of the snap ring abut against the inner wall of the engagement groove 60 and the other side abut against the outer wall of the first inner shell 31.

[0070] The output shaft has a rectangular cross-section, or is a cylindrical body with a partially chamfered edge, which allows the first inner shell 31 to be rotated by its edge.

[0071] Referring to Figures 1 to 7, the outer wall of the first inner shell 31 is covered by the first outer shell 30, and the outer wall of the second inner shell 41 is covered by the second outer shell 40. The two are mirror-symmetric with respect to the central shaft plate 12. Taking the first outer shell 30 as an example, the second outer shell 40 is made of natural rubber, preferably of food grade. A connection step is provided on one side of the first inner shell 31 facing the central shaft plate 12, and the first outer shell 30 covers the connection step so as to partially enclose it. A sealing opening 63 is provided on one side of the first outer shell 30 away from the central shaft plate 12. In order to provide mounting space for the connection structure 6, a cap 62 is fitted into the sealing opening 63 and connected. The cap 62 is tightened and fixed into the sealing opening 63, preventing the connection structure 6 from being exposed.

[0072] In this embodiment, the product's waterproof performance is set to IP54 level. Specifically, adhesive is applied to the motor, circuit board, battery, etc., effectively blocking saliva from entering the internal circuitry and structure while the dog is playing, thereby improving the product's reliability and service life.

[0073] It employs low power consumption and ergonomically designed electronic control logic, and is equipped with a radar module that automatically activates when it detects moving objects in the surroundings. If no moving objects are detected within one minute, it automatically enters standby mode to reduce power consumption.

[0074] To increase the pet's attention to the toy, an attraction rope 7 is provided, which is attached to a connecting ring 14. The role of the attraction rope 7 is to increase the pet's attention to the toy when the product is moving.

[0075] To further enhance the pet's attraction to and attachment to the toy, a recording module is incorporated. Through its recording function, memory, and speaker, the toy can be loaded with the owner's voice or other sounds that attract the pet, and played back cyclically and intermittently to capture the pet's attention and improve their interest in and attachment to the toy.

[0076] In this embodiment, magnetic charging is selected for charging, and the magnetic charging port, recording hole, sound output hole, power button, and recording button are distributed on the central shaft wall 13. Inside, a shaft ring 11 penetrates and is coupled to the circuit board, and components such as the circuit board and battery are fixed to the central shaft plate and firmly fixed by filling with adhesive.

[0077] In the specific implementation process, when using the pet electronic toy, first the attraction rope 7 is tied to the connecting ring 14, and the owner's voice or other sounds that attract the pet are recorded using the recording button. When the power button is pressed, the toy is activated, and the radar module begins detecting moving objects in the surroundings. When a moving object is detected, the main control chip on the circuit board randomly combines eight different movement patterns and automatically switches one pattern every five seconds, causing the toy to perform different actions such as moving forward, backward, and turning to attract the pet's attention.

[0078] The three support feet 10 play an important role in the toy's motion. They are evenly distributed on the outside of the central shaft 1, and their height is higher than the outer edges of the first and second rotating wheels 3 and 4, providing stable support to the central shaft 1. This allows the motor's power to effectively move the rotating wheels relative to the ground, preventing them from spinning freely in place. The outer edge shape of the support feet is rationally designed, and the angle between the torque line 82 and the common tangent 84 is acute. When the motor starts, the torque on the central shaft 1 is greater than the torque on the rotating wheels, and as the torque increases during the uphill process, the support points become more stable. At the same time, the arc curvature at the contact points of the support feet 10 is smaller than the corresponding arc curvature of the central shaft 1. The highest point is arc-shaped and concentric with the central shaft, and the rest of the outer edge curve transitions smoothly. This ensures the support effect and prevents the feet from entering the mouth of pets when they chew on them.

[0079] The structural design of the first rotating wheel 3 and the second rotating wheel 4 also ensures the normal operation of the toy. The first inner shell 31 is fixedly connected to the first outer shell 30 and is also fixed to the output end of the first motor 32, and power transmission is realized by the connection structure.
