Description

Technical Field

[0001] This invention relates to the field of toy vehicle technology, specifically to a toy vehicle shell assembly / disassembly component and a toy vehicle. Background Technology

[0002] Currently, most toy cars on the market adopt a split structure design, mainly consisting of two parts: the main body and the outer shell. In order to meet the needs of toy car internal parts inspection, style change, cleaning and maintenance, and children's independent assembly and play, most of them will set the shell as a detachable structure.

[0003] The existing connection structures between the toy car shell and the body mostly use one-piece snap-fit, screw locking, or strong pressure interference fit for fixation. Among them, the screw fixing method is cumbersome to disassemble and assemble, requires special tools, has a high operation threshold, is not conducive to children to complete the disassembly and assembly independently, and has low disassembly and assembly efficiency. Although the conventional rigid snap-fit ​​connection structure does not require tools, it is difficult to control the snap-fit ​​force. With long-term repeated disassembly and assembly, problems such as snap deformation, fatigue fracture, and loss of elasticity are prone to occur. This not only shortens the service life of the parts, but also easily leads to loose connections, car shell shaking, or even accidental detachment of the car shell during use, resulting in poor stability.

[0004] Meanwhile, traditional assembly / disassembly structures struggle to balance connection strength with ease of assembly and disassembly. Increasing the clamping force, while ensuring assembly stability, significantly increases disassembly difficulty, making it hard for children to easily separate the toy. Conversely, reducing the clamping force for easier assembly and disassembly results in excessive gaps in the assembly and loose connections, severely impacting the overall usability and play experience of the toy car. Furthermore, most existing assembly / disassembly connection structures have cluttered component arrangements, complex overall structures, and are difficult to mold, hindering mass production and resulting in relatively high production costs.

[0005] Therefore, developing a toy car shell assembly / disassembly component that is simple in structure, easy to assemble and disassemble, has a stable and reliable connection, is suitable for children to operate independently, and can effectively extend the service life has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] To solve one of the above-mentioned technical problems, the present invention provides a toy car shell assembly and disassembly component and a toy car.

[0007] This application provides the following technical solution: In a first aspect, embodiments of this application provide a toy car body disassembly and assembly assembly, comprising: A car body connector, wherein the car body connector is provided with a plug-in part and a slot is provided on the plug-in part; A vehicle body connector, comprising a bracket, a locking component, and an elastic component, wherein the bracket is provided with a slot, the locking component is rotatably disposed on the bracket, the elastic component is disposed on the bracket and one side elastically abuts against the locking component, so that the locking component always has a preload force for rotation about a first direction, and the locking component is provided with a hook. During the process of inserting the plug into the slot, the plug pushes the locking member to rotate around the second direction. When the hook and the slot are aligned, the elastic member pushes the locking member to rotate around the first direction, so that the hook engages with the slot. The plug abuts against the other side of the elastic member, and the elastic member pushes the plug in the opposite direction, so that the hook and the slot are tightly engaged. Under the action of external force, the locking component can rotate around the second direction, causing the hook to disengage from the slot, and the elastic member to elastically release and push the insertion part, causing the insertion part to disengage from the slot.

[0008] Optionally, the elastic element includes a torsion spring; One torsion arm of the torsion spring abuts against the locking component, so that the locking component always has a preload force for rotation about the first direction; With the plug inserted into the slot, the plug abuts against another torsion arm of the torsion spring, which pushes the plug in the opposite direction, causing the hook and the slot to engage tightly.

[0009] Optionally, the toy car body assembly also includes a pin; The locking component has a receiving cavity, and the torsion spring includes a helical segment and two torsion arms. The helical segment is received in the receiving cavity, and the two torsion arms extend out of the receiving cavity. The pin is fixed to the vehicle body connector and passes through the receiving cavity, and the spiral segment is sleeved on the pin.

[0010] Optionally, a rotating cavity is provided within the bracket, and the slot communicates with the rotating cavity; The inner wall of the rotating cavity is provided with a limiting step; The locking member is at least partially located within the rotating cavity, and the locking member has a limiting protrusion; During the process of inserting the plug into the slot, the plug pushes the locking member to rotate around the second direction, and the limiting protrusion moves away from the limiting step. When the hook and the slot are aligned, the elastic member pushes the locking member to rotate around the first direction, so that the hook is engaged in the slot and the limiting protrusion abuts against the limiting step. When the insertion part is disengaged from the slot, the limiting protrusion abuts against the limiting step.

[0011] Optionally, a limiting surface is provided on the inner wall of the rotating cavity; When the insertion part is disengaged from the slot, one torsion arm of the torsion spring abuts against the limiting surface; With the plug inserted into the slot, the plug pushes the torsion arm away from the limiting surface.

[0012] Optionally, the locking component includes a first extension and a second extension; There is an included angle between the first extension and the second extension; The first extension is provided with the hook and the limiting protrusion, and the second extension is provided with the limiting groove; One torsion arm of the torsion spring is inserted into the limiting groove.

[0013] Optionally, the second extension extends out of the rotating cavity and is at least partially exposed outside the bracket.

[0014] Optionally, the outer surface of the second extension is provided with a force-applying rib.

[0015] Optionally, the hook has a convex arc surface that protrudes toward one side of the slot; During the insertion of the plug into the slot, the plug abuts against the convex arc surface, causing the locking member to rotate about the second direction.

[0016] Secondly, embodiments of this application also provide a toy car, comprising: Car body and body; The aforementioned toy car body assembly / disassembly assembly includes a body shell connector connected to the car body and a body body connector disposed on the car body.

[0017] By adopting the above technical solution, this application has the following beneficial effects: The disassembly and assembly component provided in this application uses a plug-in part and a slot for insertion and engagement, along with a locking component, elastic element, and hook and slot to achieve automatic locking and positioning. During assembly, simply pushing the plug-in part in completes the locking and fixing process, making assembly simple, convenient, and efficient. The disassembly and assembly component relies on the bidirectional elastic resistance of the elastic element to ensure that the hook and slot remain tightly fitted and locked, effectively improving the stability of the connection between the car shell and the vehicle body. This prevents the car shell from loosening or falling off during toy car use, ensuring strong connection reliability. During disassembly, simply moving the locking component releases the locking limit, and the elastic element's elastic restoring force easily separates and disassembles the car shell. The disassembly and assembly steps are few, the operation is simple and easy, making it suitable for children to use. The disassembly and assembly component has few overall parts, a streamlined and compact structure, low manufacturing difficulty, controllable production costs, and is easy for mass production and market promotion. The disassembly and assembly components of this application adopt an elastic rotation locking structure instead of the traditional rigid snap-locking structure, which can effectively reduce the extrusion wear and fatigue loss of components, significantly extend the overall service life of the disassembly and assembly components, and improve the quality of product use.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Example 1: See Figures 1 to 13 As shown in the figure, this application provides a toy car shell assembly / disassembly component, including: a shell connector 1 and a body connector 2. The shell connector 1 is provided with a plug-in portion 11, and the plug-in portion 11 is provided with a slot 111. The body connector 2 includes a bracket 21, a locking component 22, and an elastic component 23. The bracket 21 is provided with a slot 211. The locking component 22 is rotatably disposed on the bracket 21. The elastic component 23 is disposed on the bracket 21, and one side elastically abuts against the locking component 22, so that the locking component 22 always has a pre-tightening force for rotation about a first direction. The locking component 22 is provided with a hook 2211. During the process of the plug-in portion 11 being inserted into the slot 211, the plug-in portion 11 pushes against the locking component. When the hook 22 rotates about the second direction, and the hook 2211 and the slot 111 are aligned, the elastic member 23 pushes the locking member 22 to rotate about the first direction, so that the hook 2211 is engaged with the slot 111, and the insertion part 11 abuts against the other side of the elastic member 23. The elastic member 23 pushes the insertion part 11 in the opposite direction, so that the insertion part 11 applies a pre-tightening force about the second direction to the locking member 22. This pre-tightening force is counteracted by the pre-tightening force that the locking member 22 always has about the first direction, so that the hook 2211 and the slot 111 always maintain a tight engagement and will not easily disengage. This engagement method relies on the bidirectional elastic resistance of the elastic member 23 to enhance the reliability of the locking engagement structure. Under the action of external force, the locking component 22 can rotate around the second direction, causing the hook 2211 to disengage from the slot 111, and the elastic member 23 elastically releases and pushes the insertion part 11, causing the insertion part 11 to disengage from the slot 211.

[0025] The disassembly and assembly component provided in this application uses the insertion part 11 to engage with the slot 211, and works in conjunction with the locking part 22, the elastic element 23, and the hook 2211 and slot 111 to achieve automatic locking and positioning. During assembly, simply push the insertion part 11 into the slot to lock and fix it. The assembly operation is simple and convenient, and the assembly efficiency is high. The disassembly and assembly component of this application relies on the bidirectional elastic resistance of the elastic element 23 to ensure that the hook 2211 and slot 111 always remain tightly fitted and locked, effectively improving the stability of the connection between the car shell 5 and the car body 6. During the use of the toy car, the car shell 5 is less likely to loosen or fall off, and the connection reliability is strong. When disassembling, the disassembly and assembly component of this application only requires moving the locking part 22 to release the locking limit. The elastic restoring force of the elastic element 23 allows for easy separation and disassembly of the car shell 5. The disassembly and assembly steps are few, the operation is simple and easy for children to use. The disassembly and assembly component of this application has a small number of parts, a simple and compact structure, low processing difficulty, controllable production costs, and is easy to mass-produce and market. The disassembly and assembly components of this application adopt an elastic rotation locking structure instead of the traditional rigid snap-lock structure, which can effectively reduce the extrusion wear and fatigue loss of the components, significantly extend the overall service life of the disassembly and assembly components, and improve the quality of product use.

[0026] It should be noted that the term "first direction" in this application refers to the rotational direction of the locking member 22 engaging with the locking insert 11, and can be understood as... Figure 5 The right-side locking member 22 rotates counterclockwise. The term "second direction" in this application refers to the rotation direction of the unlocking connector 11 of the locking member 22, and can be understood as... Figure 5 The right-side locking component 22 rotates clockwise.

[0027] In some possible implementations, the elastic element 23 includes a torsion spring, one torsion arm 231 of which abuts against the locking member 22, so that the locking member 22 always has a preload force for rotation about a first direction. When the insertion part 11 is inserted into the slot 211, the insertion part 11 abuts against the other torsion arm 231 of the torsion spring, and the torsion arm 231 pushes the insertion part 11 in the opposite direction, so that the hook 2211 and the slot 111 remain tightly engaged without any play between them, thus preventing them from accidentally disengaging.

[0028] This application uses a torsion spring as the elastic element 23, which has strong structural adaptability. The two torsion arms 231 of the torsion spring can respectively form a bidirectional elastic force on the locking component 22 and the plug-in part 11. One torsion arm 231 continuously presses against the locking component 22, so that it has a predetermined rotational preload under normal conditions, ensuring that the locking component 22 can complete the locking and resetting action independently, and the locking response is smooth and stable. After the plug-in part 11 is assembled in place, the other torsion arm 231 of the torsion spring can push the plug-in part 11 in the opposite direction. Utilizing the pressing force generated by the elastic deformation of the torsion spring itself, the hook 2211 and the slot 111 always maintain a tight fit, effectively eliminating the gap in the locking fit, greatly improving the connection structure stability of the shell 5 and the body 6. During driving and handling, the shell is less likely to loosen or shake, and the connection stability is greatly improved. The torsion spring is compact and easy to install, directly adapting to the confined space inside the bracket 21 without requiring additional complex limiting and transmission structures. This simplifies the overall assembly structure, reduces the difficulty of component assembly, and facilitates overall assembly. The torsion spring possesses excellent elastic deformation capacity and fatigue resistance, and is not prone to elastic decay or deformation failure during repeated disassembly and reassembly. It can provide stable bidirectional clamping force over a long period, effectively extending the service life of the entire assembly and reducing the product's later failure rate. This application, relying on the torsion spring's bidirectional force structure, achieves automatic locking and elastic clamping without the need for additional locking auxiliary structures, further simplifying the disassembly and reassembly process. It balances assembly strength and disassembly convenience, making it more suitable for children to operate independently.

[0029] In some possible implementations, such as Figure 1 As shown, the toy car body assembly also includes a pin 3, a locking component 22 with a receiving cavity, a torsion spring including a helical segment 232 and two torsion arms 231, the helical segment 232 being housed in the receiving cavity, the two torsion arms 231 extending out of the receiving cavity, the pin 3 being fixed to the body connector 2 and passing through the receiving cavity, and the helical segment 232 being sleeved on the pin 3.

[0030] This implementation scheme features a pin 3 and a receiving cavity within the locking component 22 to achieve integrated limiting assembly of the torsion spring. The torsion spring helical segment 232 is housed within the receiving cavity and sleeved on the outside of the pin 3. The pin 3 ensures coaxial limiting between the torsion spring and the locking component 22, guaranteeing uniform deformation of the torsion spring during rotation of the locking component 22 and preventing spring misalignment, disengagement, or jamming, thus improving motion stability. Simultaneously, the receiving cavity provides protective enclosure for the torsion spring, reducing contamination and frictional wear, improving fatigue resistance, and extending service life. This assembly structure is simple and compact, with reliable positioning, simplifying assembly processes, reducing assembly gaps, and is suitable for the limited installation space of toy cars, facilitating mold processing and mass production.

[0031] In one possible implementation, such as Figure 1 and Figure 13As shown, the pin 3 includes a cap 31 and a shaft 32. The cap 31 is connected to one end of the shaft 32, and the shaft 32 has an annular groove 321 on the side opposite to the cap 31. The toy car shell assembly includes a buckle 4 with a snap-fit ​​groove 41. The buckle 4 is positioned within the annular groove 321, and the annular groove 321 cooperates with the buckle 4 to axially engage the pin 3, preventing it from slipping out and ensuring a secure assembly. The shaft 32 passes through the body connector 2, and the cap 31 and buckle 4 are respectively positioned on both sides of the body connector 2.

[0032] In some possible implementations, such as Figure 6 As shown, a rotating cavity is provided inside the bracket 21, the slot 211 communicates with the rotating cavity, a limiting step 212 is provided on the inner wall of the rotating cavity, and a locking member 22 is at least partially located inside the rotating cavity, the locking member 22 having a limiting protrusion 2212. Figure 5 and Figure 6 As shown, during the insertion of the plug portion 11 into the slot 211, the plug portion 11 pushes the locking member 22 to rotate around the second direction, and the limiting protrusion 2212 moves away from the limiting step 212. When the hook 2211 and the slot 111 are aligned, as... Figure 7 As shown, the elastic member 23 pushes the locking member 22 to rotate around the first direction, causing the hook 2211 to engage in the slot 111, and the limiting protrusion 2212 abuts against the limiting step 212. Figure 4 As shown, when the insertion part 11 is disengaged from the slot 211, the limiting protrusion 2212 abuts against the limiting step 212.

[0033] In this embodiment, a rotating cavity is formed inside the bracket 21, and the slot 211 communicates with the rotating cavity, providing space for the insertion movement of the insertion part 11 and the rotational avoidance of the locking member 22. A limiting step 212 is provided on the inner wall of the rotating cavity, and a corresponding limiting protrusion 2212 is provided on the locking member 22, forming a mechanical limiting fit structure. The locking member 22 is at least partially housed inside the rotating cavity, and the cavity wall of the rotating cavity provides lateral constraint on the locking member 22, preventing it from swaying or shifting left and right during rotation, ensuring the stability of the rotation trajectory of the locking member 22. During the assembly process of the insertion part 11 into the slot 211, such as... Figure 5 As shown, the insertion part 11 presses against the locking member 22 and pushes the locking member 22 to rotate. At this time, the limiting protrusion 2212 moves synchronously with the locking member 22 and moves away from the limiting step 212, releasing the limiting interference and providing rotational stroke for the hook 2211 to make way; when the hook 2211 rotates with the locking member 22 to align with the slot 111, as Figure 7As shown, the elastic element 23 releases its elastic thrust and pushes the locking component 22 to rotate in the opposite direction, causing the hook 2211 to precisely engage with the slot 111 to complete the locking. At this time, the limiting protrusion 2212 returns to its original position with the locking component 22 and abuts against the limiting step 212. The limiting step 212 forms a rigid blocking limit on the limiting protrusion 2212, limiting the maximum rotation angle of the locking component 22, preventing the locking component 22 from rotating excessively under the action of the elastic element 23, and preventing the hook 2211 from being over-pressed and jammed, thus avoiding assembly jamming and disassembly jamming. At the same time, as Figure 4 As shown, after the insertion part 11 is completely disengaged from the slot 211 and the body shell 5 is disassembled, the limiting protrusion 2212 remains abutting against the limiting step 212, keeping the locking component 22 in its initial assembly posture, achieving reset positioning, and facilitating the next insertion and assembly. This limiting structure is simple and compact, requiring no additional limiting parts, and can accurately limit the rotational stroke of the locking component 22, improving the alignment accuracy between the hook 2211 and the slot 111, avoiding problems of excessive or incomplete engagement, and further enhancing the stability and reliability of the overall disassembly and assembly structure.

[0034] In some possible implementations, such as Figure 6 As shown, the inner wall of the rotating cavity is provided with a limiting surface 213. When the insertion part 11 is disengaged from the slot 211, a torsion arm 231 of the torsion spring abuts against the limiting surface 213. When the insertion part 11 is inserted into the slot 211, the insertion part 11 pushes the torsion arm 231 away from the limiting surface 213.

[0035] In this embodiment, a limiting surface 213 is further provided on the inner wall of the rotating cavity. The limiting surface 213 is used to limit and constrain the torsion arm 231 of the torsion spring, thereby achieving precise positioning of the elastic element 23. In the empty state where the insertion part 11 is disengaged from the slot 211 and the car body 5 is disassembled, the torsion spring is not subjected to the squeezing force of the insertion part 11. At this time, one of the torsion arms 231 of the torsion spring is stably abutted against the limiting surface 213. The rigid blocking of the limiting surface 213 restricts the movement of the torsion arm 231. On the one hand, it can constrain the initial opening angle of the torsion spring, keep the torsion spring in a preset elastic deformation state, and ensure that the torsion spring continuously provides a stable preload to the locking component 22. On the other hand, it can prevent the torsion arm 231 from shifting or swinging randomly without external force, avoid misalignment, loosening, and elastic fatigue shift of the torsion spring, and ensure the structural stability of the torsion spring during long-term operation. Figure 7As shown, during the assembly process of the insertion part 11 being inserted into the slot 211, the insertion part 11 moves deeper into the slot 211 and gradually pushes the torsion arm 231, causing the torsion arm 231 to be disengaged from the limiting surface 213. The torsion spring undergoes controllable elastic deformation and stores elastic potential energy. This structure integrates the limiting surface 213 within the internal space of the rotating cavity, eliminating the need for additional positioning components. The structure has a high degree of integration and a compact layout. At the same time, the cooperation between the limiting surface 213 and the torsion arm 231 regulates the deformation trajectory of the torsion spring, preventing skewing or jamming during the deformation process and ensuring a smooth and uniform output of elastic force. Combined with the aforementioned limiting step 212 for mechanically limiting the locking component 22, a dual limiting protection is achieved for both the locking component 22 and the torsion spring. This further optimizes the smoothness of the disassembly and assembly process and improves the overall component fitting accuracy and durability.

[0036] In some possible implementations, the locking member 22 includes a first extension 221 and a second extension 222, with an included angle between them. The first extension 221 is provided with the hook 2211 and the limiting protrusion 2212, and the second extension 222 is provided with a limiting groove 2221. A torsion arm 231 of the torsion spring is inserted into the limiting groove 2221. The aforementioned receiving cavity is formed between the first extension 221 and the second extension 222 for accommodating the helical segment 232 of the torsion arm 231.

[0037] In this embodiment, the locking component 22 includes a first extension 221 and a second extension 222 arranged at an angle. An angled space is reserved between the two extensions, which together form the receiving cavity. This receiving cavity is specifically used to accommodate the helical segment 232 of the torsion spring, so that the torsion spring is integrated and embedded inside the locking component 22, resulting in a compact structure and high integration. The first extension 221 is a locking and limiting functional segment, which integrates a hook 2211 and a limiting protrusion 2212 to respectively realize the functions of locking and fixing with the slot 111 and limiting rotation with the limiting step 212. The functions are concentrated and the layout is reasonable. The second extension 222 is a spring transmission segment, which has a limiting groove 2221. One of the torsion arms 231 of the torsion spring is inserted and limited in the limiting groove 2221. The limiting groove 2221 can form a wrapping constraint on the torsion arm 231, restricting the torsion arm 231 from sliding or shifting relative to the second extension 222, preventing the torsion arm 231 from slipping or misaligning during elastic compression, and ensuring that the torsion spring force can be stably and reliably transmitted to the locking component 22. The included angle formed between the two extensions not only makes the locking component 22 a lever-type force-bearing structure and forms a reasonable lever arm ratio, but also forms a receiving cavity, which has a dual beneficial effect.

[0038] In some possible implementations, such as Figure 1As shown, the second extension 222 extends out of the rotating cavity and is at least partially exposed on the bracket 21. A force-applying rib 2222 is provided on the outer surface of the second extension 222 to facilitate pressing and separating the car shell 5 and the car body 6. By extending the second extension 222 outwards, so that it at least partially extends out of the rotating cavity and is exposed on the surface of the bracket 21, a manually operable press trigger end is formed. Unlike traditional hidden locking structures, this exposed arrangement allows direct operation of the locking component 22 without disassembling the outer shell, simplifying the drive structure. Simultaneously, the force-applying rib 2222 on the outer surface of the second extension 222 increases the contact friction between the operator's fingers and the second extension 222, preventing slippage or disengagement during pressing. Considering that toy car users are mostly children, the raised rib structure optimizes the pressing feel, increases the contact area, and reduces the precision required for pressing. This allows players to easily move the second extension 222, driving the locking component 22 to rotate, thereby releasing the engagement between the hook 2211 and the slot 111, and enabling quick separation of the car shell 5 and the car body 6. Furthermore, the external structure of the second extension 222 is simple and intuitive, allowing for disassembly without tools, meeting the needs of children for easy operation. The force-applying raised rib 2222 is integrally molded into the second extension 222, eliminating the need for additional parts. This simple and reliable structure is not easily damaged and can maintain good manual control performance over a long period, further improving ease of assembly and disassembly and enhancing the user experience.

[0039] In some possible implementations, such as Figure 1 As shown, the hook 2211 has an outwardly convex arc surface 2211a protruding towards one side of the slot 211. During the process of inserting the insertion part 11 into the slot 211, as... Figure 6 As shown, the insertion portion 11 abuts against the convex arc surface 2211a, causing the locking member 22 to rotate about a second direction. The insertion end of the insertion portion 11 is provided with a narrowing body 112, the cross-section of which gradually decreases along the insertion direction of the insertion portion 11. During the insertion of the insertion portion 11 into the slot 211, the outer wall of the narrowing body 112 abuts against the convex arc surface 2211a of the hook 2211, causing the locking member 22 to rotate about a first direction.

[0040] In this embodiment, a narrowing body 112 is provided at the insertion end of the insertion part 11, and the cross-section of the narrowing body 112 gradually decreases along the insertion direction. This gradual narrowing structure can play a good guiding role in the initial stage of the insertion of the insertion part 11 into the slot 211, reducing the difficulty of aligning the insertion of the insertion part 11 into the slot 211 and avoiding insertion jamming due to alignment deviation. The outer side of the hook 2211 is provided with an outwardly convex arc surface 2211a, so that the hook 2211 forms a smoothly transitioned contact surface. During the insertion of the insertion part 11, the outer wall of the narrowing body 112 can conform to and press against the outwardly convex arc surface 2211a of the hook 2211, and achieve smooth transmission by means of arc surface contact. During the insertion process, as the narrowing body 112 continues to penetrate deeper into the slot 211, a lateral thrust is gradually applied to the outer wall of the narrowing body 112, smoothly pushing the hook 2211 so that the locking component 22 rotates around the second direction, automatically completing the repositioning and avoidance action of the locking component 22. Compared with the traditional straight-face rigid extrusion structure, this structure uses the gradual slope of the narrowing body 112 and the convex arc surface 2211a of the hook 2211 to cooperate with each other, and the contact position can be adaptively slid and adjusted, eliminating the need for precise manual alignment. Even with slight assembly deviations, the insertion and pushing action can still be completed smoothly, greatly reducing the difficulty of the insertion operation. At the same time, the arc-shaped contact reduces the extrusion stress and frictional resistance during the insertion process, avoiding scratches, jamming, and plastic wear from hard edges, ensuring a smooth and gentle insertion process, suitable for children's gentle insertion and removal operations, and further improving the smoothness of the assembly and disassembly process and the durability of the structure.

[0041] Example 2: Figure 3 As shown, Embodiment 2 of this application also provides a toy car, including: a car shell 5, a body 6, and a toy car shell assembly / disassembly assembly as described above. The car shell connector 1 of the toy car shell assembly / disassembly assembly is connected to the car shell 5, and the body connector 2 of the toy car shell assembly / disassembly assembly is disposed on the body 6.

[0042] The toy car using this car shell 5 assembly / disassembly component allows for quick assembly, locking, and disassembly of the car shell 5 and body 6 via the insertion and engagement of the connector 11 and slot 211, along with the locking component 22 and elastic element 23. The overall structure is compact and rationally designed, with the assembly / disassembly components concealed to minimize damage from external impacts. An exposed second extension 222 serves as a press trigger, facilitating manual unlocking by the player. Simultaneously, the bidirectional clamping property of the elastic element 23 ensures no looseness or gaps after assembly, preventing the car shell 5 from easily shaking or falling off during driving and play, resulting in high overall assembly stability. This toy car has a low assembly / disassembly threshold, allowing children to independently assemble and disassemble it for play, enhancing its playability and user experience. Furthermore, the overall components are durable, effectively extending the toy car's lifespan.

[0043] In some possible implementations, such as Figure 1As shown, the body shell connector 1 also includes a crossbeam 12 and two insertion parts 11. The two insertion parts 11 are respectively fixedly installed at both ends of the crossbeam 12, making the body shell connector 1 an integrated frame structure. The crossbeam 12 has connection holes 121, which can be fastened to the body shell 5 by fasteners passing through the connection holes 121. The fixing method is reliable and easy to disassemble and assemble. The two insertion parts 11 are symmetrically arranged along the width direction of the body shell 5, so that the stress points are evenly distributed on both sides of the body shell 5, ensuring that the body shell 5 is subjected to balanced force. Correspondingly, the bracket 21 of the body body connector 2 is provided with two side extension arms 215. The two side extension arms 215 are respectively provided with slots 211. The slots 211 on both sides are matched and inserted one by one with the insertion parts 11 on both sides to achieve simultaneous locking on both sides. The bracket 21 has mounting holes 214, and fasteners are also used to complete the fixed assembly of the bracket 21 and the body 6. The assembly method is simple and the connection is firm. To further enhance the overall assembly stability of the toy car, two sets of car shell 5 assembly components can be configured. Two sets of body connecting parts 2 are spaced apart at both ends of the body 6 along its length, and two sets of car shell connecting parts 1 are correspondingly installed on the car shell 5. By adopting a multi-point assembly structure with double-sided locking in the width direction and double-set arrangement in the length direction, the relative displacement between the car shell 5 and the body 6 can be constrained from multiple directions in the lateral and longitudinal directions, significantly improving the fit of the car shell 5 assembly and effectively suppressing shaking, displacement, and abnormal noise caused by driving bumps. This symmetrical arrangement structure has uniform stress distribution, strong stability, and a regular structural layout, which facilitates one-piece molding, reduces mass production costs, and is suitable for mass production of toy cars.

[0044] The following describes in detail the disassembly and assembly process of the vehicle body 5 according to this application, with reference to the accompanying drawings: like Figure 2 and Figure 4 As shown, in the initial state where the car body 5 and the car body 6 are not connected, the torsion spring maintains its initial preload. Under the constraint of the elastic force of the torsion spring, the locking component 22 inside the car body connector 2 maintains a fixed initial posture. The limiting protrusion 2212 on the locking component 22 stably abuts against the limiting step 212 on the inner wall of the rotating cavity, realizing the initial limit of the rotation stroke of the locking component 22. At the same time, one of the torsion arms 231 of the torsion spring abuts against the limiting surface 213 of the rotating cavity. The limiting surface 213 positions and constrains the torsion arm 231, so that the torsion spring maintains a preset deformation angle, ensuring that the locking component 22 and the torsion spring maintain a regular and stable initial position in the idle state, providing a stable structural foundation for subsequent assembly operations.

[0045] During the assembly of the car body 5 and the car body 6, such as Figure 4 and Figure 5The operator aligns the insertion part 11 on the body shell connector 1 with the slot 211 of the body body connector 2, and moves the body shell 5 towards the side of the body 6, so that the insertion part 11 is gradually inserted into the slot 211. During the insertion of the insertion part 11, the narrowing body 112 at the end of the insertion part 11 first contacts the convex arc surface 2211a of the hook 2211. Utilizing the gradual slope of the narrowing body 112 and the smooth fit of the convex arc surface 2211a, it smoothly presses against the hook 2211 and pushes the locking component 22 to rotate in the second direction with the pin 3 as the rotation center. During this process, the torsion spring undergoes elastic deformation and stores elastic potential energy driven by the locking component 22. The limiting protrusion 2212 on the locking component 22 rotates synchronously with the locking component 22, gradually disengaging from the limiting step 212 and releasing the rigid rotation limit. As the insertion part 11 continues to penetrate deeper into the slot 211, the end of the insertion part 11 further presses against the torsion arm 231 of the torsion spring, driving the torsion arm 231 to disengage from the limiting surface 213, further increasing the deformation of the torsion spring and continuously increasing the elastic energy stored. Figure 7 As shown, when the insertion part 11 is inserted into place, and the slot 111 and the hook 2211 are precisely aligned, the elastic potential energy accumulated by the torsion spring is released, pushing the locking component 22 to rotate and reset in the first direction, causing the hook 2211 to quickly engage with the slot 111. At this time, the limiting protrusion 2212 abuts against the limiting step 212 again, completing the mechanical limiting of the locking component 22. The hook 2211 and the slot 111 form a stable fastening structure, thereby completing the stable assembly of the body shell 5 and the body 6. Figure 8 As shown, the torsion arm on one side of the elastic member 23 pushes the insertion part 11 in the opposite direction, so that the insertion part 11 applies a pre-tightening force rotating about the second direction to the locking member 22. This pre-tightening force is counteracted by the pre-tightening force that the locking member 22 always has rotating about the first direction, so that the hook 2211 and the slot 111 always maintain a tight engagement and will not easily disengage. This engagement method relies on the bidirectional elastic resistance of the elastic member 23 to enhance the reliability of the locking engagement structure.

[0046] like Figures 10 to 12As shown, when the body shell 5 needs to be disassembled, the operator manually presses the second extension 222 exposed on the bracket 21. The force-applying ribs 2222 on the surface of the second extension 222 increase the friction of the fingers, preventing slippage and facilitating stable application of pressing force. External force drives the locking component 22 to rotate around the pin 3 in the second direction. The hook 2211 deflects synchronously with the locking component 22 and disengages from the slot 111, releasing the locking state. After the hook 2211 is unlocked, the torsion spring is released elastically again. The torsion arm 231, which was previously squeezed by the insertion part 11, pushes the insertion part 11 in the opposite direction, providing the insertion part 11 with a pushing force to disengage from the slot 211. This assists the insertion part 11 in moving out of the slot 211 in the disengagement direction, realizing the automatic separation of the body shell 5 from the body 6. When the insertion part 11 is completely disengaged from the slot 211, the torsion spring returns to its initial shape, one of the torsion arms 231 abuts against the limiting surface 213 again, and at the same time the limiting protrusion 2212 abuts against the limiting step 212 again, so that the locking part 22 returns to its empty initial position, completing the quick disassembly and reset of the car body 5 and the body 6, so as to carry out the next assembly operation.
