Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of splicing toys, in particular to a wooden toy convenient to splice. BACKGROUND

[0002] In the children's toy market, wooden toys are always favored by parents and children due to their natural environmental protection, safety, durability, and the ability to stimulate children's creativity and imagination. Especially in the critical stage of the growth of infants and young children, wooden toys not only provide entertainment but also promote the physical development and cognitive ability of children during play. However, the existing wooden toy cars on the market, especially those designed for young children, have several significant technical limitations that limit the versatility, educational value, and safety of the toy cars, which are specifically reflected in the following aspects: Lack of modular design: Most current wooden toy cars adopt fixed structures, and the components cannot be modularly disassembled and reassembled. This design not only limits the variety of play methods of the toy, reduces the opportunities for children to explore and learn new things through hands-on operations, but also gradually reduces the interest and appeal of the toy over time, making it difficult to meet the changing growth needs of children.

[0003] Single function positioning: Existing wooden toy cars mainly focus on simple pushing or pulling play, lacking integration of multi-functionalities such as walking assistance, role-playing, and creative construction. Especially for infants and young children learning to walk, there is a lack of specially designed walking assistance functions, which cannot effectively exercise their balance and coordination abilities during play.

[0004] Speed control missing: For pushable wooden toy cars, especially those designed for the walking stage, there is often no reasonable speed adjustment mechanism. During pushing, the vehicle may accelerate too quickly due to smooth ground or excessive pushing force, increasing the risk of collision or falling for infants and young children when using it, posing a safety hazard.

[0005] Poor compatibility of riding and pushing: Many wooden toy car designs do not fully consider the different needs of children at different stages of growth, especially when children grow up and want to sit in the car and be pushed by others. The existing design often cannot meet this demand, lacking corresponding structural support such as adjustable seats, safety belts, or easy-to-grip handles for adults.

[0006] In summary, the existing wooden toy car has obvious deficiencies in modular design, multifunctionality, safety and adaptability, and cannot fully meet the diversified needs of infants and young children in the growth process. Therefore, developing a new type of wooden toy car that integrates modular disassembly and assembly, walking aid, speed control, and compatibility of riding and pushing is of great significance to improve the educational value, safety and interest of children's toys, and is also a technical problem to be solved in the current toy industry.

DETAILED DESCRIPTION

[0026] The technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In the prior art, wooden toy cars generally adopt fixed structure design, and the components cannot be modularized, disassembled and reorganized, resulting in single play and inability to adapt to the growth needs of children. There is a safety hazard of sliding too fast during the pushing process of the toy car. The function design of the vehicle body 101 fails to take into account the needs of walking aid and riding, and it is difficult to meet the use scenarios of children of different ages.

[0028] In order to solve the above problems, it is found in the development process that the contradiction between structural stability and disassembly convenience needs to be solved in modular design, and mechanical balance is achieved through symmetrical layout. Speed control needs to add a one-way transmission mechanism in the power transmission link to avoid inertia out of control. Function expansion needs to set up independent drive units on both sides of the vehicle body 101 to realize mode switching through split structure.

[0029] Therefore, the application provides a wooden toy including a vehicle body 101, two housings 107 are symmetrically arranged on the outer side of the vehicle body 101, and the housings 107 are internally provided with a splicing assembly and connected with the vehicle body 101. A detachable vertical rod 102 is arranged in the housings 107, the bottom of the vertical rod 102 is connected with a transmission assembly, a first gear 205 is arranged on the left side of the transmission assembly, the outer side of the first gear 205 is connected with a control assembly and a first wheel 103, and a second wheel 104 is arranged on the right outer end of the housings 107.

[0030] The vehicle body 101 is a bearing main structure, which can be formed by processing a rectangular wooden block, and is used for providing a basic support and a module docking platform. The housing 107 is a detachable shell, which can adopt a hollow wooden frame structure and form an expansion interface through symmetric arrangement. The splicing assembly is a connecting mechanism, which can adopt a plate-shaped structure with a sliding clamping groove, and realizes detachable fixing of the housings 107 and the vehicle body 101. The vertical rod 102 is a vertical support, which can adopt a cylindrical wooden rod and forms temporary connection with the housings 107 through plug-in connection. The transmission assembly is a power transmission mechanism, which can adopt a gear and sleeve 201 combined structure, and converts movement of the vertical rod 102 into wheel power. The control assembly is a movement limiting device, which can adopt a ratchet and pawl 303 mechanism, and realizes one-way rotation control of the wheel. The first wheel 103 is a driving wheel, which can adopt a rubber-coated wooden hub, and obtains rotary power through gear transmission. The second wheel 104 is a driven wheel, which can adopt a full-wood structure and forms a support point through fixing on the right side of the housings 107.

[0031] Specifically, the vehicle body 101 is a core bearing structure, and forms an expandable interface through the symmetrically arranged housings 107. The splicing assembly adopts a sliding clamping mode, so that the housings 107 can be pushed and pulled and disassembled along the surface of the vehicle body 101. When the housings 107 are installed, the internal vertical rod 102 is inserted into the sleeve 201 of the transmission assembly to form a power connection, and the transmission assembly converts the swing of the vertical rod 102 into the rotary motion of the first wheel 103 through gear meshing. The ratchet mechanism in the control assembly limits the wheel to rotate in one direction only, and generates resistance to realize speed attenuation during pushing. The second wheel 104 on the right side of the housings 107 forms a stable support point, and constitutes a differential layout with the first wheel 103 on the left side, and automatically adjusts the speed during turning. When it is necessary to switch the function mode, the transmission path is changed by disassembling the housings 107, so that the vehicle body 101 can be converted into a saddle shape.

[0032] Compared with the prior art, the symmetric housings 107 design breaks through the limitation of the traditional fixed structure, and realizes conversion of multiple modes through modular disassembly. The combination structure of the transmission assembly and the control assembly solves the problem of uncontrollable pushing speed, and realizes automatic speed reduction by mechanical limiting. The differential layout of the double wheels takes into account the stability of straight-line pushing, and adapts to the operation needs of children of different ages.

[0033] Through the above-mentioned technical solution, this application achieves modular reconfiguration of the toy car, allowing children to change the vehicle's configuration by disassembling and assembling the housing 107. During the pushing process, the gear transmission and ratchet mechanism work together to effectively reduce the sliding speed and prevent accidental acceleration. The independent wheel systems on both sides of the vehicle body 101 can switch drive modes according to the usage scenario, simultaneously meeting the needs of learning to walk and riding and playing. The detachable connection between the housing 107 and the vehicle body 101 ensures structural stability while facilitating independent assembly by children.

[0034] The present application further proposes that the splicing assembly includes a first card plate 105 and a second card plate 106 , which are fixedly connected to the inner side of the shell 107 and slidably connected to the outer side of the vehicle body 101 .

[0035] The first and second clamps 105 and 106 are two positioning components provided on the inner side of the housing 107, which can be implemented using a mortise and tenon structure or a dovetail groove structure, and are used to establish a rigid connection between the housing 107 and the splicing assembly. The sliding connection refers to a guide rail structure provided on the outer side of the vehicle body 101, which can be implemented using a T-shaped slide rail or a grooved guide rail, allowing the clamps to move in a specific direction.

[0036] Specifically, the housing 107 is fixedly connected to the splicing assembly via a first clip 105 and a second clip 106. During the splicing process, the clips are embedded within a pre-set guide track on the vehicle body 101. When an external force is applied to the housing 107, the clips move linearly along the track until they reach a limit point at the end of the track and lock into place. During disassembly, a reverse force is applied to release the clips from the limit point, allowing them to slide out along the track. This structure achieves reversible assembly between the housing 107 and the vehicle body 101 through the synergistic effect of mechanical limits and sliding fit.

[0037] Compared to existing technologies, traditional wooden toy cars rely on gluing or screwing, making components non-detachable. This solution, however, utilizes a combination of clips and guide rails to achieve modular assembly and disassembly while maintaining connection stability. While existing technologies lack reusable mechanical connection mechanisms, this solution utilizes a composite structure of physical stoppers and sliding fits, avoiding the safety hazards associated with using small parts while also meeting the needs of children for repeated operation.

[0038] Through the technical scheme, the technical defect that the wooden toy car cannot be modularly spliced is solved, the shell 107 can be quickly mounted to the vehicle body 101 or separately detached for use as an independent component. The detached shell 107 can be horizontally placed for a child to operate the vertical rod 102 or the wheel component, thereby expanding the play variety of the toy. The matching structure of the clamping plate and the track ensures the connection strength while reducing the operation complexity, so that a preschool child can independently complete the splicing and detaching actions.

[0039] The application further proposes that the transmission assembly comprises a sleeve 201, the middle part of the sleeve 201 is rotationally connected with the shell 107, the sleeve 201 is slidingly connected with the vertical rod 102, and the bottom inner side of the sleeve 201 is provided with a cylindrical rod 202.

[0040] The sleeve 201 is a hollow cylindrical structure and can be implemented by using a hard plastic material. The middle part of the sleeve 201 is rotationally connected with the shell 107 through a bearing, so that the sleeve 201 can rotate around its own axis. The sleeve 201 is slidingly connected with the vertical rod 102, that is, the inner wall of the sleeve 201 is provided with a sliding rail or a guide groove, and the outer wall of the vertical rod 102 is provided with a corresponding protrusion or a sliding block, so that the vertical rod 102 can move axially along the sleeve 201 to achieve disassembly or position adjustment. The cylindrical rod 202 is a rigid rod fixed to the bottom inner side of the sleeve 201 and can be implemented by using a metal rod or a high-strength plastic rod. The axis of the cylindrical rod 202 is parallel to the axis of the sleeve 201 and is used to transmit the power generated by the rotation of the sleeve 201.

[0041] Specifically, when the vertical rod 102 is inserted into the sleeve 201, the rotational movement of the sleeve 201 is transmitted to the vertical rod 102 through the cooperation of the sliding rail and the vertical rod 102, and the axial position of the vertical rod 102 can be adjusted to change the contact length of the sleeve 201 and the vertical rod 102. The cylindrical rod 202 at the bottom of the sleeve 201 is linked with other components in the transmission chain during the rotation process, for example, is engaged with a gear or a rack 204, so as to convert the rotational kinetic energy into linear or deceleration movement. By adjusting the sliding position of the vertical rod 102 in the sleeve 201, the effective transmission ratio of the transmission assembly can be changed, so as to limit the wheel speed and avoid the vehicle from accelerating too fast due to smooth ground or excessive external force during the pushing process.

[0042] Compared with the prior art, the transmission structure of the traditional wooden toy car is mostly a fixed gear set, which cannot dynamically adjust the transmission efficiency according to the external force. However, the sleeve 201 and the vertical rod 102 are slidingly connected in the present scheme, and the cylindrical rod 202 forms a power transmission path, thereby forming an adjustable transmission assembly that can adaptively adjust the transmission resistance during the pushing process to achieve speed control.

[0043] Through the technical scheme, the application solves the problem of too fast acceleration of the wooden toy car due to lack of speed adjustment mechanism, and through the detachable sliding connection structure and axial transmission design, dynamic adjustment of the pushing resistance is realized without increasing complex mechanical components, effectively reducing the risk of vehicle out of control and improving the use safety.

[0044] The application further provides that the outer side of the cylindrical rod 202 is provided with a limiting rod 203, the left side of the limiting rod 203 is provided with a rack 204, and the top of the rack 204 is in meshing connection with a first gear 205.

[0045] The cylindrical rod 202 refers to a rod-shaped structure in the transmission assembly that is in sliding connection with the sleeve 201, and can be specifically implemented by a smooth-surfaced wooden cylinder, for transmitting the rotary motion of the sleeve 201 and driving the limiting rod 203 to move laterally. The limiting rod 203 refers to a lateral constraint component fixed to the outer side of the cylindrical rod 202, and can be specifically implemented by a rectangular wooden strip connected to the cylindrical rod 202 through a mortise and tenon structure, for limiting the axial displacement range of the cylindrical rod 202 to avoid speed out of control due to excessive movement of the transmission assembly. The rack 204 refers to a rack-shaped structure fixedly connected to the left side of the limiting rod 203, and can be specifically implemented by a wooden strip with uniform tooth grooves formed on the surface, for converting the lateral linear motion of the limiting rod 203 into the rotary motion of the first gear 205. The first gear 205 refers to a gear component in meshing connection with the rack 204, and can be specifically implemented by a wooden disc with uniformly distributed teeth on the circumference, for forming transmission resistance through the meshing relationship between the rack 204 and the gear, so as to adjust the wheel speed.

[0046] Specifically, when the toy car is pushed, the vertical rod 102 drives the sleeve 201 to rotate, the rotation of the sleeve 201 causes the cylindrical rod 202 to slide axially, and in turn drives the limiting rod 203 to move laterally. The lateral movement of the limiting rod 203 drives the rack 204 to move synchronously, and the meshing of the rack 204 and the first gear 205 converts the linear motion into the rotary motion of the gear. Due to the setting of the gear transmission ratio, the rack 204 needs to overcome the mechanical resistance generated by the rotation of the gear when moving, and the resistance and the pushing force form a dynamic balance, so that the wheel speed is limited within a controllable range. By adjusting the meshing depth or the number of gear teeth of the rack 204 and the gear, the resistance can be further controlled, so as to realize accurate control of the speed.

[0047] Compared with the prior art, the traditional wooden toy car usually adopts a fixed transmission structure, lacks an active control mechanism for the pushing speed, and the scheme combines the movement amplitude limitation of the transmission assembly with the gear resistance to form a dynamic balance system through the linkage design of the limiting rod 203 and the rack 204. In the prior art, the gear and the transmission component are usually independently arranged and cannot be adjusted in speed through mechanical linkage, while the scheme automatically generates resistance during pushing through the meshing relationship between the rack 204 and the gear, and the speed control can be realized without additional operation.

[0048] Through the above technical scheme, the application solves the problem of excessive acceleration of the wooden toy car caused by excessive pushing force or smooth ground, limits the wheel speed through the dynamic balance of mechanical resistance and pushing force, ensures that the speed of the toy car pushed by the child is always within a safe range, and reduces the risk of collision or falling.

[0049] The control assembly further comprises a rotating block 301, and two pawls 303 are arranged on the inner side of the rotating block 301 in a circumferential manner.

[0050] The rotating block 301 is a rotating component for transmitting power and can be realized by ABS engineering plastic injection molding, and the two pawls 303 arranged on the inner side of the rotating block 301 in a circumferential manner are used to form an engaged or separated state with the transmission component. The pawl 303 is a metal component with one-way locking function and can be realized by stamping forming of high-carbon steel, and the spring 304 arranged on the inner side of the pawl 303 is used to provide elastic restoring force to ensure that the pawl 303 is stably engaged with the transmission component without external force. The spring 304 is a mechanical element for storing elastic potential energy and can be realized by a stainless steel coil spring 304, for example, with an elastic coefficient range of 5-10 N / mm, which is used to adjust the engagement force between the pawl 303 and the transmission component.

[0051] Specifically, when the toy car is pushed, the rotating block 301 rotates with the wheel, the pawl 303 is engaged with the transmission component under the action of the spring 304, and the wheel speed is limited; when the wheel accelerates due to excessive pushing force, the pawl 303 is compressed by the reverse force of the transmission component to disengage and release the transmission component to achieve deceleration; when the pushing force decreases, the spring 304 resets the pawl 303 to re-engage, forming periodic speed adjustment. In this process, the circumferential arrangement of the two pawls 303 uniformly distributes the load, avoiding wear caused by single-point stress concentration, and the elastic adjustment function of the spring 304 can adapt to the difference in pushing force under different ground friction coefficients.

[0052] Compared with the existing technology, traditional wooden toy cars generally use fixed gear transmission and have no speed control mechanism. However, this solution achieves dynamic speed adjustment through the cooperation of the pawl 303 and the spring 304, without the need for additional electronic components or complex mechanical structures. While maintaining the environmental characteristics of wooden toys, it effectively solves the safety hazard caused by inertial acceleration.

[0053] Through the above technical solution, this application achieves automatic speed control during the propulsion of a toy car. When the propulsion force exceeds a set threshold, pawl 303 disengages from the transmission component to release kinetic energy, preventing the vehicle from losing control due to inertial acceleration. When the propulsion force returns to normal, pawl 303 reengages to maintain stable driving. This solution achieves safe and reliable dynamic speed regulation through a purely mechanical structure, and the elastic parameters of spring 304 can be adjusted to suit the propulsion force characteristics of children of different ages.

[0054] The present application further proposes that an electromagnet 305 is provided on the outside of the spring 304 , and the inside of the electromagnet 305 is fixedly connected to the rotating block 301 .

[0055] The electromagnet 305 is a device that generates a magnetic field using electric current, and can be implemented by winding a coil around an iron core. Its function is to adjust the compression of the spring 304 through magnetic force, thereby controlling the meshing state between the pawl 303 and the ratchet block 306. The fixed connection of the rotating block 301 refers to the relative stationary state between the electromagnet 305 and the rotating block 301 maintained by a mechanical structure, and can be implemented by bolts or snap fasteners. Its function is to ensure that the electromagnet 305 moves synchronously with the rotation of the rotating block 301, thereby preventing control failure due to displacement deviation.

[0056] Specifically, electromagnet 305 is positioned outside spring 304. When electromagnet 305 is energized, the magnetic attraction it generates acts on spring 304, changing the compression of spring 304 and thereby adjusting the locking force of pawl 303 on ratchet block 306. When electromagnet 305 is de-energized, spring 304 returns to its initial state, and pawl 303 and ratchet block 306 maintain normal engagement. The fixed connection between electromagnet 305 and rotating block 301 ensures that the two remain synchronized during rotation, preventing the direction of magnetic force from shifting due to relative displacement, thereby ensuring the stability of the control assembly under dynamic conditions. By adjusting the current intensity of electromagnet 305, the locking force of pawl 303 can be precisely controlled, thereby limiting the wheel speed and preventing safety hazards caused by excessive pushing of the toy car.

[0057] Compared with the prior art, the existing wooden toy car usually adopts a pure mechanical ratchet structure, can only realize one-way locking function, and cannot actively adjust the locking force according to the use scene. The scheme introduces the cooperation structure of electromagnet 305 and spring 304, increases the dynamic adjustment ability based on current control on the basis of retaining the mechanical locking function, so that the vehicle speed control is more flexible and has strong adaptability.

[0058] Through the above technical scheme, the present application realizes active control of the pushing speed of the toy car, and the pawl 303 locking force can be changed by adjusting the current intensity of the electromagnet 305, so as to limit the wheel speed and avoid vehicle speed out of control due to smooth ground or excessive pushing force. The scheme significantly improves the safety of the toy car in the learning stage while ensuring the reliability of the mechanical structure.

[0059] The present application further proposes that the outer side of the pawl 303 is engaged with a ratchet block 306, and the outer side of the ratchet block 306 is provided with a second gear 307.

[0060] The pawl 303 is a rigid member with an inclined tooth surface, which can be realized by stamping or injection molding of hard plastic, and the tooth angle is configured to allow the ratchet block 306 to rotate freely when pushed forward, and to form mechanical locking when reversed. The ratchet block 306 is an annular component with continuous tooth grooves, which can be realized by injection molding of high-density polyethylene material, and the tooth groove pitch matches the tooth pitch of the pawl 303, forming a one-way transmission physical constraint. The second gear 307 is a transmission component with external engagement teeth, which can be realized by turning processing of beech wood and embedding with a metal shaft sleeve, and the number of teeth forms a certain transmission ratio with the third gear 308, converting the rotational motion of the ratchet block 306 into linear motion of the wheel.

[0061] Specifically, the pawl 303 is kept in engagement with the ratchet block 306 by the pre-tightening force of the spring 304, and when the toy car is pushed, the ratchet block 306 rotates forward with the second gear 307, at which time the pawl 303 slides along the tooth groove slope without resistance; when the pushing speed exceeds the set threshold, the ratchet block 306 tends to rotate reversely due to inertia, the pawl 303 is embedded in the tooth groove to form mechanical locking, and the braking torque is transmitted to the wheel through the engagement relationship between the second gear 307 and the third gear 308. The second gear 307 provided on the outer side of the ratchet block 306 as a power transmission node has fewer teeth than the third gear 308, for example, a 1:2 transmission ratio, so that the ratchet block 306 rotates one revolution corresponding to half a revolution of the third gear 308, while maintaining the smoothness of pushing and increasing the system inertia damping.

[0062] Compared with the prior art, the traditional wooden toy car only relies on the friction between the wheels and the ground to realize deceleration, and the scheme automatically triggers mechanical braking through the cooperation of the ratchet mechanism and the gear set during the acceleration stage of the vehicle. The scheme using electromagnetic braking or hydraulic damping in the prior art needs additional energy supply and has a complex structure, and the scheme uses a pure mechanical structure to realize speed control, avoiding the safety hazards of electronic elements in children's toys.

[0063] Through the above technical scheme, when the pushing speed of the vehicle exceeds the safety threshold, the engagement and locking of the pawl 303 and the ratchet block 306 are automatically triggered, the braking torque is directly acted on the wheel shaft through gear transmission, effectively preventing the vehicle from running out of control due to smooth ground or excessive pushing force. The mechanical speed control mechanism does not produce additional resistance in the normal pushing state, and only intervenes in braking in the case of abnormal acceleration, which not only ensures the smooth experience of children playing, but also eliminates the risk of tipping caused by sudden speed changes.

[0064] The left side of the second gear 307 is engaged with the third gear 308, and the third gear 308 is connected with the inner side of the first wheel 103.

[0065] The second gear 307 is an intermediate transmission component, which can be implemented by a gear structure with a specific number of teeth, used to receive power transmission from the control assembly and form a speed reduction structure. The third gear 308 is an output gear, which can be implemented by a gear structure that forms an engagement relationship with the second gear 307, used to transmit the reduced power to the first wheel 103. The connection between the third gear 308 and the inner side of the first wheel 103 is an axial fixed structure of the gear and the wheel, which can be implemented by key groove cooperation or bolt fixation to ensure the stability of power transmission.

[0066] Specifically, the engagement relationship between the second gear 307 and the third gear 308 forms a multi-stage speed reduction transmission chain, and the transmission efficiency is changed by adjusting the gear ratio between the gears, thereby reducing the rotational speed of the first wheel 103. The third gear 308 is directly connected with the inner side of the first wheel 103, so that the reduced power is transmitted to the wheel, avoiding the free acceleration of the wheel due to direct external pushing. The second gear 307 as an intermediate transmission component not only receives the limiting action of the control assembly, but also outputs the controlled power to the wheel through the third gear 308, forming a double speed constraint mechanism.

[0067] Compared with the prior art, the existing wooden toy car usually adopts a single gear or no transmission control structure, which causes the wheels to accelerate too fast during pushing due to smooth ground or external force. The scheme introduces the engagement structure of the second gear 307 and the third gear 308 to form a multi-stage speed reduction transmission chain, effectively limiting the rotational speed of the wheels and solving the safety hazards caused by the lack of transmission control in the prior art.

[0068] Through the above technical solution, the present application realizes accurate control of the wheel rotation speed of the wooden toy car, avoids the risk of collision or falling caused by excessive acceleration of the wheels during pushing, and significantly improves the safety of the toy car.

[0069] Compared with the prior art, the traditional wooden toy car usually adopts a single-stage gear or direct drive structure, lacks a speed reduction design, and thus the wheel rotation speed is directly related to the pushing force, which poses a safety hazard. The present solution realizes rotation speed control through two-stage gear meshing, without relying on electronic components or complex mechanisms, and thus improves safety while maintaining a pure mechanical structure. In the prior art, the connection between the gear and the wheel usually adopts an external shaft or additional support, which has a long transmission path and is prone to loosening, while the present solution directly connects the gear and the wheel on the inside, making the structure more compact and stable.

[0070] Through the above technical solution, the present application solves the safety hazard problem caused by uncontrollable speed during the pushing process of the wooden toy car, limits the wheel rotation speed through a gear meshing speed reduction mechanism, and avoids excessive acceleration of the vehicle. At the same time, the direct connection of the gear and the wheel on the inside reduces the loosening risk of the transmission structure, ensures the stability of power transmission, and makes the toy car move more smoothly and controllably when used by children in the learning-to-walk stage.

[0071] The above only describes the embodiments of the present application and is not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
