[0002] With the development of science and technology and the improvement of living standards, the children's toy market is becoming increasingly prosperous, and various novel and unique toys are constantly emerging. Among them, rotating toys are deeply loved by children because of their strong fun and simple operation. Traditional aircraft toys mainly rely on manual pulling ropes or hand twisting to start the rotation. Although the structure is simple, the gameplay is relatively single, and certain skills are required to make the aircraft rotate stably for a long time, which may be difficult for younger children.
[0003] In recent years, the progress of electronic technology and mechanical design has led to the rapid development of electrically driven toys. Some battery-powered aircraft launchers equipped with motors have appeared on the market.

Fig. 9 The above schematic diagram is only for showing the structural relationship related to the invention point, and is not the actual scale of the actual product.
[0071] like Figures 1 to 9 As described above, a toy catapult gun in this embodiment includes: a shell 1, an electric rotation drive component 2, a clutch storage and launch component 3 and a flight component 4.
[0072] The shell 1 is the main structure of the entire toy aircraft 41 gun, which provides protection for the internal mechanical components and defines the overall shape of the toy. The shell 1 also provides a portion for the user to hold. It is usually made of plastic and has a streamlined design. The shell 1 is designed with a handle portion suitable for holding by hand for easy operation, and there is an opening (muzzle) at the front end for the clutch storage and firing component 3 to extend.
[0073] The electric rotary drive assembly 2 uses the motor 21 to provide power to rotate the flying assembly 4 at high speed, providing sufficient kinetic energy for the flying device 41 to enable it to rotate stably and be launched. It includes a small motor, a transmission mechanism 22 and other components. After the motor is started, the power is transmitted to the output end through a series of deceleration and torque increase mechanisms. It is small and compact, suitable for the internal space limitation of the toy; it is powered by batteries and is easy to carry and use.
[0074] The clutch power storage and launch assembly 3 is responsible for launching the aircraft 41 from the muzzle at a certain rotation speed. A spring or elastic material may be used as an energy storage element. One end of it is directly connected to the output shaft of the electric rotary drive assembly 2, and the other end extends outside the housing 1. The design is sophisticated, which can ensure that the aircraft 41 leaves the device smoothly and unhindered; the force is properly controlled, which can effectively launch the aircraft 41 and avoid causing harm.
[0075] The flying component 4 is the object that is finally launched, and it flies by relying on its own weight and the rotational momentum given by the electric rotary drive component 2 and the clutch power storage and launching component 3. The overall shape is mostly circular or other symmetrical geometric bodies, and the surface may have decorative patterns to increase the ornamental value. The appearance design is diverse to meet the preferences of children of different ages.
[0076] Specifically, the electric rotary drive assembly 2 is arranged in the housing 1; the clutch power storage and firing assembly 3 is arranged in the housing 1, one end of which extends from the muzzle of the housing 1, and the other end is connected to the output end of the electric rotary drive assembly 2; the flying assembly 4 is arranged outside the housing 1, and is connected to one end of the clutch power storage and firing assembly 3; a switch 5 is arranged at the muzzle of the housing 1, and when the flying assembly 4 is connected to one end of the clutch power storage and firing assembly 3, the flying assembly 4 is close to or pressed on the switch 5; a controller 6 is arranged in the housing 1, and is connected to the switch 5 and the electric rotary drive assembly 2 respectively. At this time, the switch 5 can detect whether the flying assembly 4 is installed in place.
[0077] In this embodiment, the switch can be a button, a laser or an infrared sensor or the like.
[0078] In one embodiment, the electric rotary drive assembly 2 includes: a motor 21 and a transmission mechanism 22; the power cord of the motor 21 is connected to the controller 6, and the power output end of the motor 21 is connected to the input end of the transmission mechanism 22; the output end of the transmission mechanism 22 is connected to the other end of the clutch power storage and launching assembly 3, and is suitable for driving the clutch power storage and launching assembly 3 to perform energy storage action.
[0079] The electric rotary drive assembly 2 is designed to effectively transmit the rotational force of the motor 21 to the flying assembly 4, and realize high-speed rotation and launch of the aircraft 41 through the clutch power storage and launch assembly 3.
[0080] The power output end of the motor 21 is directly connected to the input end of the transmission mechanism 22, and will eventually be connected to one end of the clutch power storage and launching component 3, ensuring that when the motor 21 is started, the rotational motion it generates can be effectively transmitted to the flying component 4, causing it to rotate quickly in preparation for launch.
[0081] The controller 6 sends out instructions (using digital or analog signals for communication, depending on the specific type of motor 21 selected and its control requirements) and transmits them to the motor 21 through the power line, and controls the start of the motor 21 according to the user operation (when the flying component 4 is close to or squeezed on the switch 5), and controls the motor 21 to rotate a preset number of circles, for example, ten circles.
[0082] Specifically, the motor 21 may be a stepper motor 21, a Hall effect motor 21 (with a Hall sensor), a counting motor 21, etc. These types of motors 21 can provide precise speed control and positioning capabilities.
[0083] Stepper motor 21: Suitable for applications that require precise angle control. It can accurately rotate a fixed angle according to the number of input pulses.
[0084] Hall effect motor 21: The Hall effect is used to detect the rotor position, thereby achieving closed-loop speed or position control and improving the responsiveness and stability of the system.
[0085] Counting motor 21: generally refers to a DC motor 21 with a built-in encoder or other form of position feedback mechanism for accurately measuring the number of rotations of the motor 21 shaft.
[0086] The transmission mechanism 22 is used to amplify or reduce the power output by the motor 21 in an appropriate proportion, and may change the direction, so as to adapt to the clutch storage and launch component 3. The transmission mechanism 22 can be selected from the following types:
[0087] Gear set: It is composed of multiple gears, and the final output speed and torque can be adjusted by adjusting the gear ratio. It is suitable for situations where high-efficiency transmission is required.
[0088] Worm gear: The worm gear combination can provide a larger reduction ratio and has a self-locking feature, which can maintain the current position after the power is cut off.
[0089] Pulley: Use a belt to connect two wheels of different sizes, and adjust the diameter ratio of the two to achieve the speed change effect. This method is relatively quiet, but may not be as durable as the gear system.
[0090] As shown in the accompanying drawings, in this embodiment, a gear set is used as the transmission mechanism 22, including a pinion and a large gear that mesh with each other. The center position of the pinion is fixedly connected to the output end of the motor 21, and the center position of the large gear is connected to the clutch power storage and launch assembly 3 (specifically, the transmission rod 32 in the clutch power storage and launch assembly 3).
[0091] In one embodiment, the clutch power storage and firing assembly 3 includes: a trigger 31, a transmission rod 32 and a spring 33; one end of the trigger 31 extends out of the housing 1 for finger pressing; the middle part of the trigger 31 is rotatably connected to the inner wall of the housing 1; one end of the transmission rod 32 is connected to the flight assembly 4, and the other end abuts against the other end of the trigger 31; the transmission rod 32 is bidirectionally clutched and connected to the output end of the electric rotation drive assembly 2; the spring 33 is installed between the housing 1 and the transmission rod 32, and is suitable for driving the transmission rod 32 to rotate and return to a position engaged with the output end of the electric rotation drive assembly 2.
[0092] The trigger 31 is designed to be easy to pull with a finger, and usually has an arc or groove to adapt to the natural gripping posture of the human hand. Its overall structure is relatively strong to withstand repeated operations. When the user pulls the trigger 31 with a finger, the trigger 31 rotates around the axis connected to the inner wall of the housing 1. This rotation triggers the entire firing mechanism, causing the spring 33 to release its stored energy.
[0093] The transmission rod 32 is usually in the shape of a straight rod, so that one end can effectively dock with the one-way clutch of the flight assembly 4, and the other end can be against the trigger 31. Its length and diameter are adjusted according to specific needs to ensure sufficient strength to transmit force. In order to ensure that the transmission rod 32 can only move along its axial direction, a mounting plate 9 is provided in the housing 1, and a through hole is provided on the mounting plate 9 for passing the transmission rod 32, and a hole is also provided on the center of the large gear. In order to keep the large gear and the small gear in the axial direction, two mounting plates 9 are used, and the large gear and the small gear are arranged between the two mounting plates 9.
[0094] In one embodiment, one end of the spring 33 is fixedly connected to the transmission rod 32, and the other end is fixedly connected to the housing 1. The spring 33 is generally in a spiral form and surrounds the transmission rod 32. Its size (such as wire diameter, number of turns) and material selection directly affect the elastic coefficient of the spring, that is, how much energy it can store and how to release this energy efficiently. The function of the spring 33 is to store the rotational energy from the electric rotary drive assembly 2. After the trigger 31 is pulled, the transmission rod 32 moves forward and separates from the electric rotary drive assembly 2. The spring 33 releases energy, drives the transmission rod 32 to rotate, and then drives the flight assembly 4 to be launched.
[0095] In another embodiment, the spring 33 includes a first spring adapted to drive the transmission rod 32 to rotate and a second spring adapted to drive the transmission rod 32 to return to engage with the output end of the electric rotation drive assembly 2. In this embodiment, the function of the spring 33 in the above embodiment is divided into two separate parts, namely, the first spring adapted to drive the transmission rod 32 to rotate and the second spring adapted to drive the transmission rod to return to engage with the output end of the electric rotation drive assembly 2.
[0096] The first spring (rotation drive spring) is specifically used to store the rotation energy from the electric rotation drive assembly 2, and release this energy to drive the transmission rod 32 to rotate during launch, thereby pushing the flight assembly 4. One end is fixed to the housing 1, and the other end is connected to the transmission rod 32. Specifically, it may be wrapped around the transmission rod 32 or directly act on one side of the transmission rod 32 by other means.
[0097] The second spring (reset spring) is responsible for automatically pulling the transmission rod 32 back to its original position after the launch is completed, so that it re-engages with the output end of the electric rotary drive assembly 2 to prepare for the next launch. One end is fixed to the housing 1, and the other end is also connected to the transmission rod 32, but is usually located at a different position from the first spring to ensure that the two do not interfere with each other.
[0098] When the motor 21 is started and transmits power to the clutch power storage and launching assembly 3 through the transmission mechanism 22, the first spring starts to store energy. At this time, the second spring is in a natural state without additional tension.
[0099] The user pulls the trigger 31 to trigger the entire launch mechanism. The first spring quickly releases the stored energy, pushing the transmission rod 32 to move forward and rotate, so that the flight assembly 4 obtains enough kinetic energy to be launched. At the same time, the second spring also begins to deform under force to prepare for subsequent reset.
[0100] After the launch is completed, the first spring returns to the initial state and no longer applies thrust. At this time, the second spring uses its own elastic restoring force to smoothly pull the transmission rod 32 back to the starting position, so that it is engaged with the output end of the electric rotary drive assembly 2 again, completing a complete launch cycle.
[0101] More specifically, the transmission rod 32 is provided with a circumferential bite portion 34; the output end of the electric rotary drive assembly 2 is provided with a bite portion 23 adapted to the circumferential bite portion 34; when the circumferential bite portion 34 is adapted to be connected with the bite portion 23, the output end of the electric rotary drive assembly 2 can drive the transmission rod 32 to rotate synchronously. The trigger 31 has a pulling stroke greater than the matching depth of the circumferential bite portion 34 and the bite portion 23.
[0102] In the design of the toy catapult gun, the cooperation between the circumferential bite portion 34 on the transmission rod 32 and the bite portion 23 at the output end of the electric rotary drive assembly 2 is a key mechanism, which ensures that the rotational energy generated by the motor 21 can be effectively transmitted to the transmission rod 32 and can be separated smoothly during the launch. The following is a detailed introduction to this mechanism:
[0103] The circumferential engaging portion 34 (located on the transmission rod 32) is generally a series of protrusions or grooves arranged at one end of the transmission rod 32, and these structures are evenly distributed along the circumference of the transmission rod 32. This design enables the engaging portion to form a good meshing with the engaging portion 23 of the electric rotary drive assembly 2.
[0104] Material selection: Plastic or metal materials with a certain hardness and wear resistance are usually used to ensure durability for long-term use.
[0105] When the transmission rod 32 is connected to the electric rotary drive assembly 2 , the rotation torque generated by the motor 21 is directly transmitted to the transmission rod 32 through the close contact between the bite portion and the bite portion 23 , so that the transmission rod 32 rotates synchronously with the motor 21 .
[0106] The bite portion 23 (located at the output end of the electric rotary drive assembly 2), when the transmission mechanism 22 in the electric rotary drive assembly 2 adopts a small gear and a large gear that mesh with each other, the bite portion 23 is located on the end face of the large gear close to the muzzle.
[0107] The bite portion 23 is designed to be in a shape that can match the circumferential bite portion 34 on the transmission rod 32, and may be a gear-shaped, polygonal or other forms of concave-convex structure. Such a design ensures that there is enough contact area between the two to transmit power. It is also necessary to select durable materials with an appropriate friction coefficient to prevent slipping and reduce wear. As a key component of power transmission, the bite portion 23 must be firmly combined with the circumferential bite portion 34 to provide a stable power transmission path during the operation of the motor 21. At the same time, it also needs to be able to easily disengage from the bite state under the action of appropriate external force (such as when the trigger 31 is pulled) so that the transmission rod 32 can move freely to perform the firing action.
[0108] The function implementation process is as follows:
[0109] Initial state: When the aircraft 41 is installed in place, the circumferential engaging portion 34 of the transmission rod 32 and the engaging portion 23 of the electric rotary drive assembly 2 are engaged with each other, ready to receive power from the motor 21 .
[0110] Rotation transmission: Once the motor 21 is started, the bite portion 23 starts to rotate, and through its close contact with the circumferential bite portion 34, drives the transmission rod 32 to rotate synchronously, thereby driving the transmission rod 32 and the spring 33 mounted thereon to rotate.
[0111] Separation and firing: As the user pulls the trigger 31, the transmission rod 32 is pushed forward, the bite portion 23 and the bite portion are separated, and the flight assembly 4 is separated from the muzzle, and the transmission rod 32 rotates under the action of the spring 33. The rapid rotation of the transmission rod 32 drives the flight assembly 4 to rotate and fire the flight assembly 4.
[0112] In one embodiment, an overrunning clutch assembly is further included; the overrunning clutch assembly is disposed between the transmission rod 32 and the housing 1 , or between the transmission rod 32 and the flying assembly 4 , or between the flying assembly 4 and the housing 1 .
[0113] The overrunning clutch assembly can be set in one of three positions:
[0114] 1. Between the transmission rod 32 and the housing 1;
[0115] 2. Between the transmission rod 32 and the flight assembly 4;
[0116] 3. Between the flight assembly 4 and the outer shell 1.
[0117] The main function of the overrunning clutch assembly is to achieve one-way rotation transmission and prevent reverse rotation. It allows free rotation in one direction, while preventing rotation or slipping in the opposite direction. This design ensures that power can only be transmitted in the intended direction and can protect the system from overload or unnecessary stress in some cases. The following are its specific functions:
[0118] 1. Between the transmission rod 32 and the housing 1.
[0119] Ensure that the transmission rod 32 can only rotate in one direction relative to the housing 1. For example, when the motor 21 drives the transmission rod 32 to rotate, the overrunning clutch assembly allows the transmission rod 32 to work normally; and when the transmission rod 32 attempts to rotate in the opposite direction, the overrunning clutch assembly prevents such movement.
[0120] This prevents the reverse torque caused by unexpected situations (such as launch obstruction) from causing damage to the motor 21 and other internal mechanical parts. This helps to extend the service life of the system and improve safety.
[0121] By allowing free sliding in the non-working state, the friction between the transmission rod 32 and the housing 1 is reduced, thereby reducing wear.
[0122] 2. Between the transmission rod 32 and the flying assembly 4.
[0123] It is ensured that when the transmission rod 32 drives the flying assembly 4 to rotate synchronously, power is transmitted only in a specific direction. For example, when the motor 21 drives the transmission rod 32 to rotate, the flying assembly 4 can obtain sufficient rotational kinetic energy; and once the launch process is started, the flying assembly 4 will not be dragged back or stuck even if the transmission rod 32 continues to rotate. The transition from the power storage state to the launch state is smoother, which reduces unnecessary vibration or impact and improves the consistency and accuracy of the launch.
[0124] The transmission rod 32 can quickly return to the initial position under the action of the spring and re-engage with the flight assembly 4 to prepare for the next launch. This process does not require additional manual intervention, which simplifies the user's operating steps.
[0125] 3. Between the flight assembly 4 and the outer shell 1.
[0126] When the flight assembly 4 is installed in place, the overrunning clutch assembly can ensure that it is firmly connected to the housing 1 to prevent accidental detachment when it is not ready for launch. At the same time, during the launch process, it can allow the flight assembly 4 to smoothly detach from the housing 1 to ensure smooth launch action. It prevents the flight assembly 4 from deflecting or falling off due to external interference or improper operation when rotating at high speed, thereby enhancing the safety of use. It ensures that the flight assembly 4 is properly aligned before launch, thereby improving the directionality and accuracy of the launch.
[0127] In a specific embodiment, the overrunning clutch assembly is arranged between the flying assembly 4 and the transmission rod 32; the overrunning clutch assembly includes an elastic ratchet 42 arranged at any one of the two positions, the center of the flying assembly 4 and the end of the transmission rod 32, and a ratchet 36 at the other of the two positions. There are two different schemes for this embodiment:
[0128] Solution 1: The elastic ratchet 42 is located at the center of the flying assembly 4 , and the ratchet wheel 36 is located at the end of the transmission rod 32 .
[0129] Specifically, the flying assembly 4 includes an aircraft 41 and an elastic ratchet 42 connected to the aircraft 41; one end of the transmission rod 32 is provided with a ratchet 36 adapted to engage with the elastic ratchet 42;
[0130] The ratchet wheel 36 and the elastic ratchet teeth 42 are used to realize the overrunning clutch cooperation between the flying assembly 4 and the transmission rod 32 .
[0131] One end of the clutch power storage and launching component 3 is fixedly connected with a ratchet 36 that fits and engages with the elastic ratchet 42 ; the engagement of the ratchet 36 with the elastic ratchet 42 realizes a one-way clutch connection between the flight component 4 and one end of the clutch power storage and launching component 3 .
[0132] The flying device 41 is the part that is finally launched, and usually has a symmetrical shape, such as a circle or other geometric bodies, to ensure smooth rotation. The central part of the flying device 41 has an axial hole for installing the elastic ratchet 42.
[0133] The elastic ratchet 42 is a special structure installed on the aircraft 41. It is a series of small teeth made of a material with a certain elasticity (such as plastic or rubber). These teeth are arranged along one end surface of the aircraft 41 and can be slightly bent. The design of the elastic ratchet 42 allows it to form a one-way bite with the ratchet 36 in the clutch storage and firing assembly 3.
[0134] The ratchet 36 is located at one end of the transmission rod 32, and its surface is provided with a tooth groove that matches the elastic ratchet 42. When the elastic ratchet 42 is engaged with the ratchet 36, the cooperation between them allows free rotation in one direction, but is locked in the opposite direction. This means that once the motor 21 drives the transmission rod 32 to rotate, the elastic ratchet 42 can easily slide from the ratchet 36 without causing the elastic ratchet 42 and the aircraft 41 to rotate with the ratchet 36. When launching, the ratchet 36 rotates in the opposite direction, which drives the elastic ratchet 42 and the aircraft 41 to rotate with the ratchet 36, thereby realizing the function of one-way clutch.
[0135] Solution 2: The ratchet 36 is located at the center of the flying assembly 4 , and the elastic ratchet 42 is located at the end of the transmission rod 32 .
[0136] The difference between the second solution and the first solution is that the positions of the ratchet wheel 36 and the elastic ratchet tooth 42 are interchanged, which will not be described in detail here.
[0137] In one embodiment, the flight assembly 4 is also provided with a circumferential clamping protrusion 43; the muzzle of the housing 1 is provided with a clamping groove adapted to the circumferential clamping protrusion 43; when the flight assembly 4 is connected to one end of the clutch power storage and firing assembly 3, the circumferential clamping protrusion 43 is adapted to be clamped with the clamping groove. The matching depth of the circumferential bite portion 34 on the transmission rod 32 and the bite portion 23 in the electric rotary drive assembly 2 is greater than the axial bite depth of the clamping protrusion (43) and the clamping groove.
[0138] More specifically, the pulling stroke of the trigger 31>the matching depth between the circumferential engaging portion 34 and the engaging portion 23>the axial engaging depth between the engaging protrusion 43 and the engaging groove.
[0139] The circumferential snap-fit protrusions 43 are a series of protrusions arranged on the edge of the flying component 41, which are evenly distributed along the circumference of the flying component 4 (i.e., on the outside of the elastic ratchet 42). These snap-fit protrusions can be small blocks, protrusions or other shapes, and the key is that they need to accurately match the snap-fit grooves at the muzzle of the housing 1.
[0140] A groove of a specific shape, i.e., a snap-in groove, is provided inside or around the muzzle. The snap-in groove corresponds to the circumferential snap-in protrusion 43 on the flight assembly 4. When the flight assembly 41 is installed at the muzzle position, the snap-in protrusion will snap into the corresponding snap-in groove. After the trigger 31 is pulled, the transmission rod 32 moves forward, so that the snap-in protrusion is separated from the snap-in groove, and the contact limit function is realized. The function of the snap-in protrusion and the snap-in groove is to increase the friction force to prevent the flight assembly 4 from falling off in the axial direction.
[0141] The design of the circumferential clamping protrusion 43 and the clamping groove ensures the precise positioning of the aircraft 41 before firing, thereby improving the directionality and accuracy of firing. The user only needs to put the aircraft 41 into the muzzle, and the positioning can be automatically completed without additional adjustment. Such a design helps prevent the aircraft 41 from accidentally falling off when it is not ready to fire, thereby increasing the safety of use.
[0142] Here, the clamping protrusion 43 is tightly matched with the clamping groove. The tightly matched structure ensures that the aircraft 41 will not be offset or disengaged due to centrifugal force or other external forces when rotating at high speed, thereby improving the stability and accuracy of the launch. It can also effectively prevent the aircraft 41 from falling out of the muzzle when it is not ready to launch, thereby reducing potential safety hazards. When the aircraft 41 is correctly installed in place, the clamping protrusion 43 will squeeze the switch 5, informing the controller 6 to start the motor 21 for preloading, ensuring that the launch process can only be started after the aircraft 41 is fully installed.
[0143] In one embodiment, an axial connecting protrusion 44 is provided on one of the flight component 4 or the clutch power storage and launching component 3; a connecting groove 35 adapted to the axial connecting protrusion 44 is provided on the other of the flight component 4 or the clutch power storage and launching component 3; the connecting groove 35 and the connecting protrusion 44 are arranged at the center position of the component.
[0144] In this embodiment, two solutions are included:
[0145] Solution 1: An axial connecting protrusion 44 is provided on the flying component 4 , and a connecting groove 35 is provided on the clutch storage and launching component 3 .
[0146] Specifically, an axial connecting protrusion 44 is also provided on one end of the flying component 4 close to the clutch power storage and launching component 3; a connecting groove 35 adapted to the axial connecting protrusion 44 is provided on one end of the clutch power storage and launching component 3; when the flying component 4 is connected to one end of the clutch power storage and launching component 3, the axial connecting protrusion 44 is inserted into the connecting groove 35.
[0147] The axial connection protrusion 44 is located at one end of the aircraft 41 close to the clutch power storage and firing assembly 3, and is generally a small protrusion or pin, which protrudes along the axial direction of the aircraft 41. The axial connection protrusion 44 is designed to be inserted into the connection groove 35 on the clutch power storage and firing assembly 3, thereby achieving a more secure connection.
[0148] The connection groove 35 is arranged at one end of the transmission rod 32 close to the aircraft 41, and its position corresponds to the axial connection protrusion 44 on the aircraft 41. The connection groove 35 can be circular, square or other shapes, as long as it can be closely matched with the axial connection protrusion 44.
[0149] When the user places the aircraft 41 at the muzzle, the user first needs to align the axial connection protrusion 44 on the aircraft 41 and insert it into the connection groove 35 on the clutch power storage and firing assembly 3. At the same time, the circumferential snap-in protrusion 43 on the aircraft 41 also needs to be snapped into the snap-in groove at the muzzle of the shell 1, so that the dual positioning of the aircraft 41 and the clutch power storage and firing assembly 3 and the shell 1 is completed. The dual positioning mechanism ensures the precise positioning of the aircraft 41 before firing, and improves the directionality and accuracy of the firing. Although there are multiple positioning points, the user only needs to simply put the aircraft 41 into the designated position to automatically complete all necessary connections and positioning. This design helps prevent the aircraft 41 from accidentally falling off when it is not ready to fire, thereby increasing the safety of use.
[0150] Solution 2: An axial connecting protrusion 44 is provided on the clutch power storage and launching component 3, and a connecting groove 35 is provided on the flying component 4.
[0151] The only difference between Solution 2 and Solution 1 is that the positions of the connecting protrusion 44 and the connecting groove 35 are interchanged, which will not be described in detail here.
[0152] In the above embodiment, the aircraft 41 may be a flying saucer or a bamboo dragonfly, etc.
[0153] A battery assembly 7 is also included; the battery assembly 7 is arranged in the housing 1 and is electrically connected to the controller 6. The battery assembly 7 is usually arranged inside the housing 1 to keep the overall appearance neat and tidy and protect the battery from the external environment. Disposable dry batteries or rechargeable batteries (such as nickel-cadmium batteries, nickel-metal hydride batteries or lithium batteries) can be used. The type of battery to be selected depends on design requirements, cost considerations and the expected frequency of use. The battery assembly 7 is electrically connected to the controller 6 by wires or direct contact. This is usually achieved through spring contacts or metal sheets to ensure a stable power supply. The main function of the battery assembly 7 is to provide the required power for the electric rotary drive assembly 2 (motor 21), the controller 6 and other possible electronic components (such as LED indicator lights, etc.). For rechargeable batteries, the battery assembly 7 also acts as an energy storage, allowing the user to use the toy multiple times without an external power source.
[0154] The controller 6 adjusts the output voltage according to the type of battery used to ensure that all connected electronic devices can work properly. The controller 6 is responsible for monitoring and controlling the current flowing to the motor 21 and other components to prevent overload or short circuit. In some advanced designs, the controller 6 can also detect the battery power and remind the user to replace or recharge the battery through an indicator light or sound when the battery is low.
[0155] The controller 6 has a built-in overheat protection circuit, which will automatically cut off the power supply when the temperature is detected to be too high, avoiding potential safety risks. Reverse polarity protection can also be set to prevent users from inserting batteries incorrectly and causing electrical damage. The controller 6 usually has a reverse polarity protection function. Short circuit protection: In the event of a short circuit, the controller 6 can respond quickly and disconnect the power supply to protect the battery and electronic components from damage.
[0156] In one embodiment, it also includes a compartment cover 8; a battery receiving compartment penetrating both sides of the housing 1 is provided at the handle of the housing 1; the battery assembly 7 is installed in the battery receiving compartment; and the compartment cover 8 is buckled at the opening of the battery receiving compartment.
[0157] The battery compartment is located in the handle portion of the housing 1, so that the space in the handle can be used to accommodate the battery without affecting the overall appearance and operability of the toy. The shape and size of the battery compartment are designed according to the type of battery used to ensure that the battery can be placed firmly inside. It is usually designed to be a rectangular or cylindrical space that can just hold the required number of batteries. The battery compartment runs through both sides of the housing 1, which means that the battery can be inserted or removed from both sides. This design facilitates the installation and removal of the battery.
[0158] The compartment cover 8 is usually made of durable plastic, and sometimes a material with a certain degree of flexibility is used to facilitate opening and closing. The compartment cover 8 can be buckled at the opening of the battery compartment in a variety of ways, for example:
[0159] Snap-on type: The compartment cover 8 is provided with a snap-on, which can be directly snapped into the groove on the edge of the battery compartment to achieve quick opening and closing.
[0160] Sliding type: The compartment cover 8 is designed to slide along a track and is opened and closed by a push-pull action.
[0161] Screw fixing: For more secure fixing, the compartment cover 8 may be connected to the housing 1 by screws or other fasteners, which require tools to open.
[0162] In addition, the connection between the compartment cover 8 and the battery compartment should be tight to prevent dust and moisture from entering the battery compartment and to prevent the battery from accidentally falling off.
[0163] In another embodiment, the bin cover 8 is U-shaped; the middle of the bin cover 8 is wrapped around the bottom end of the handle; both sides of the bin cover 8 cover the opening; and both ends of the bin cover 8 are respectively snap-connected with the housing 1 .
[0164] The middle part of the compartment cover 8 is designed to wrap around the bottom of the handle, and the two sides extend to the openings of the battery compartment and completely cover these openings, thereby protecting the internal battery assembly 7 from the influence of the external environment. The two ends of the compartment cover 8 are designed with buckles or other locking mechanisms, which can be firmly engaged with the corresponding positions on the housing 1. This type of engagement is usually achieved by pressing to achieve quick closing and opening.
[0165] The operation steps of the compartment cover 8 are as follows:
[0166] Open the compartment cover 8: The user can gently press specific positions at both ends of the compartment cover 8 (usually places indicated by arrows or grooves) to loosen the buckles, and then pull the compartment cover 8 out from the bottom of the handle.
[0167] Replacing the battery: Once the compartment cover 8 is removed, the user can directly access the battery compartment and correctly install or replace the battery according to the positive and negative polarity markings.
[0168] Close the compartment cover 8: Replace the compartment cover 8 to the bottom of the grip, making sure that both sides of the compartment cover 8 completely cover the opening of the battery compartment. Then, gently press both ends of the compartment cover 8 until you hear a "click" sound or feel the snap into place, indicating that the compartment cover 8 is securely fixed.
[0169] The compartment cover 8 covers the openings of the two battery compartments at the same time, which is convenient and fast to operate, simplifies the structure and improves the user experience. At the same time, the symmetrical structure is more stable, which is both practical and highly reliable in actual applications.
