Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to a toy car. Background Technology

[0002] Currently, most common children's toy cars on the market (such as balance bikes, bicycles, tricycles, and four-wheeled vehicles) adopt a non-foldable design, which results in them taking up a lot of space and being inconvenient for home storage and carrying when going out.

[0003] While some children's toy car products have incorporated folding structures in related technologies, they typically only fold once, and the folded size remains relatively large, failing to effectively improve space utilization. This causes considerable inconvenience for users in terms of use and storage, especially in scenarios with limited living space or frequent moving, thus impacting the user experience. Furthermore, existing toy cars cannot be stably placed after folding, increasing the difficulty of storage.

[0004] Therefore, there is an urgent need for a toy car to solve the above problems. Utility Model Content

[0005] Based on the above problems, the purpose of this utility model is to provide a toy car that can reduce the volume after folding and ensure the stability of the toy car after folding, making it convenient for users to carry and store when going out, and providing a better user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A toy car is provided, comprising:

[0008] beam;

[0009] A front wheel assembly, the front wheel assembly being rotatably connected to a first end of the crossbeam;

[0010] A rear wheel assembly, which is rotatably connected to the second end of the crossbeam;

[0011] The toy car has a folded state and an unfolded state. When the toy car is in the folded state, both the front wheel assembly and the rear wheel assembly are rotated and folded to be close to the crossbeam, and at least one of the front wheel assembly and the rear wheel assembly is supported on the support base.

[0012] As an optional embodiment of the toy car of this utility model, when the toy car is in the folded state, the front wheel assembly is supported on a support base.

[0013] As an optional embodiment of the toy car of this utility model, the front wheel assembly includes a first bracket and a front wheel disposed on the first bracket. When the toy car is in the folded state, the first bracket rotates toward the second end of the crossbeam to fold under the crossbeam. The end of the first bracket and the front wheel are both supported on the support base.

[0014] As an optional embodiment of the toy car of this utility model, the end of the first bracket and the front wheel are arranged in a triangular pattern;

[0015] The front wheel assembly includes two front wheels spaced apart from the first bracket. The toy car also includes a decorative piece disposed on the first bracket. The decorative piece has a support protrusion, and the support protrusion and the two front wheels form a triangle.

[0016] As an optional embodiment of the toy car of this utility model, when the toy car is converted to the folded state, the front wheel assembly rotates toward the second end of the crossbeam, the rear wheel assembly rotates toward the first end of the crossbeam, and both the front wheel assembly and the rear wheel assembly are folded under the crossbeam.

[0017] And / or, the front wheel assembly includes two front wheels spaced apart, and the rear wheel assembly includes two rear wheels spaced apart, wherein the distance between the two front wheels is greater than or less than the distance between the two rear wheels.

[0018] As an optional embodiment of the toy car of this utility model, in the folded state, the crossbeam, the rear wheel assembly, and the front wheel assembly are arranged sequentially in the vertical direction;

[0019] The front wheel assembly includes a first bracket and a front wheel disposed on the first bracket. When the toy car is in the folded state, the rear wheel assembly is folded between the first bracket and the crossbeam.

[0020] The rear wheel assembly includes a second bracket, a first end of the crossbeam is rotatably connected to the first bracket, and a second end of the crossbeam is rotatably connected to the second bracket.

[0021] As an optional embodiment of the toy car of this utility model, the first bracket includes a first connecting part and a first wheel frame. When the toy car is in the folded state, the first connecting part extends in the vertical direction, the first wheel frame is located below the crossbeam, and an accommodating space is formed between the first bracket and the crossbeam. The rear wheel assembly is located within the accommodating space.

[0022] The first bracket has two front wheels spaced apart, and the rear wheel assembly is folded between the two front wheels.

[0023] As an optional embodiment of the toy car of this utility model, the first bracket includes a first crossbar and two first wheel frames spaced apart from the first crossbar, wherein the front wheel is rotatably mounted on the end of the first wheel frame away from the first crossbar;

[0024] And / or, the second bracket includes a second crossbar and two second wheel frames spaced apart from the second crossbar, and the rear wheel assembly further includes a rear wheel, the rear wheel being rotatably mounted on one end of the second wheel frame away from the second crossbar.

[0025] As an optional embodiment of the toy car of this utility model, the support height of the front wheel assembly is greater than that of the rear wheel assembly. When the toy car is in the unfolded state, the crossbeam is tilted. When the crossbeam is lifted under the action of external force, the front wheel assembly can automatically rotate and fold relative to the crossbeam under the action of gravity.

[0026] As an optional embodiment of the toy car of this utility model, the front wheel assembly includes a first bracket, and the rear wheel assembly includes a second bracket. When the toy car is in the folded state, the first bracket and the second bracket rotate and fold towards each other, forming a ring-shaped frame structure.

[0027] The beneficial effects of this utility model are as follows:

[0028] The toy car provided by this utility model has both its front and rear wheel assemblies rotatably connected to a crossbeam. When folding the toy car, the front and rear wheel assemblies are rotated relative to the crossbeam, causing them to align with the crossbeam. By folding the front and rear wheel assemblies in both directions, the length of the toy car is significantly shortened, effectively reducing its folded volume and making it easier for users to store or carry, thus improving the user experience. Furthermore, since at least one of the front and rear wheel assemblies is supported by a support base—for example, the front and / or rear wheel assemblies can be folded under the crossbeam—they support the toy car when it is folded, preventing it from tipping over and ensuring its stability, thus reducing the difficulty of storing it.

[0059] Example 1

[0060] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a toy car that reduces its folded size while ensuring its stability when folded, making it convenient for users to carry and store, and providing a better user experience. The toy car includes a crossbeam 1, a front wheel assembly 2, and a rear wheel assembly 3.

[0061] The crossbeam 1 has a first end 11 and a second end 12. The front wheel assembly 2 is rotatably connected to the first end 11 of the crossbeam 1, and the rear wheel assembly 3 is rotatably connected to the second end 12 of the crossbeam 1. The toy car has a folded state and an unfolded state. When the toy car is in the folded state, both the front wheel assembly 2 and the rear wheel assembly 3 are rotated and folded to be close to the crossbeam 1, and at least one of the front wheel assembly 2 and the rear wheel assembly 3 is supported on a supporting base.

[0062] In this embodiment, the toy car has front wheel assembly 2 and rear wheel assembly 3 rotatably connected to crossbeam 1. When folding the toy car, the front wheel assembly 2 and rear wheel assembly 3 are rotated relative to crossbeam 1, causing them to align with crossbeam 1. By bidirectionally folding the front wheel assembly 2 and rear wheel assembly 3, the length of the toy car is significantly shortened, effectively reducing its folded volume and making it easier for users to store or carry, thus improving the user experience. Furthermore, since at least one of the front wheel assembly 2 and rear wheel assembly 3 is supported by a support base—for example, the front wheel assembly 2 and / or rear wheel assembly 3 can be folded under crossbeam 1—when the toy car is folded, the front wheel assembly 2 and / or rear wheel assembly 3 can be supported by the support base to prevent the toy car from tipping over, thereby ensuring the stability of the toy car and reducing the difficulty of storing it. The support base can be the ground, a table, etc.

[0063] Optionally, when the toy car is in the folded state, the front wheel assembly 2 is supported by the support base. That is, the entire toy car is supported by the front wheel assembly 2. At this time, the rear wheel assembly 3 can be located below or above the crossbeam 1, and the rear wheel assembly 3 can be in contact with the support base or not.

[0064] For example, in some embodiments, the front wheel assembly 2 can be designed to fold down to the bottom of the crossbeam 1, and the rear wheel assembly 3 can be designed to fold up to the top of the crossbeam 1, using the front wheel assembly 2 to support the folded toy car.

[0065] In some embodiments, both the front wheel assembly 2 and the rear wheel assembly 3 can be designed to fold down below the crossbeam 1, with the front wheel assembly 2 supporting the folded toy car, or both the front wheel assembly 2 and the rear wheel assembly 3 can support the folded toy car.

[0066] Of course, in some other embodiments, the rear wheel assembly 3 can be designed to fold down to the bottom of the crossbeam 1, and the front wheel assembly 2 can be designed to fold up to the top of the crossbeam 1, so that the rear wheel assembly 3 can support the folded toy car.

[0067] Optionally, see Figure 1 , Figure 2 , Figure 3 and Figure 5 The front wheel assembly 2 includes a first bracket 21 and a front wheel 22 disposed on the first bracket 21. When the toy car is in a folded state, the first bracket 21 rotates toward the second end 12 of the crossbeam 1 to fold under the crossbeam 1. Both the end of the first bracket 21 and the front wheel 22 are supported on the support base. That is, the front wheel assembly 2 is stably supported on the support base through the cooperation of the first bracket 21 and the front wheel 22, so that the folded toy car is placed stably.

[0068] See Figure 1 , Figure 4 and Figure 5 The end of the first bracket 21 and the front wheel 22 are triangularly distributed. When the toy car is folded, the end of the first bracket 21 and the front wheel 22 are in contact with the support base, forming a three-point support, which can improve the stability of the toy car after it is folded.

[0069] Optionally, the front wheel assembly 2 includes two front wheels 22 spaced apart from each other on the first support 21. The toy car also includes a decorative piece 4 disposed on the first support 21. The decorative piece 4 has a support protrusion 41. When the toy car is folded, the support protrusion 41 and the two front wheels 22 are all supported on the support base, forming a triangle with the support protrusion 41 and the two front wheels 22. That is, after the toy car is folded, the support protrusion 41 on the decorative piece 4 faces the support base, and the support protrusion 41 and the two front wheels 22 contact the support base, forming a three-point support, which can more stably support the toy car in the folded state and ensure the stability of the toy car after folding. The support base can be the ground, a table, etc.

[0070] Optionally, the decorative part 4 can be changed to different styles according to design requirements to make the toy car more beautiful and enhance its aesthetic appeal.

[0071] In some other embodiments, the front wheel assembly 2 may also include a front wheel 22, and the first bracket 21 has two support ends. The two support ends and the front wheel 22 form a triangle, so that the toy car can form a three-point support after folding, thereby improving the placement stability of the toy car.

[0072] Optionally, see Figure 1 and Figure 2 The front wheel assembly 2 includes two front wheels 22 spaced apart, and the rear wheel assembly 3 includes two rear wheels 32 spaced apart. The distance between the two front wheels 22 is greater than the distance between the two rear wheels 32. This arrangement ensures that when the toy car is folded, the two rear wheels 32 can be positioned between the two front wheels 22 after folding forward (e.g., ...). Figure 5 As shown in the figure, the space between the two front wheels 22 is fully utilized to further reduce the size of the toy car after folding, making it easier for users to store and carry.

[0073] In other embodiments, the distance between the two front wheels 22 can be designed to be smaller than the distance between the two rear wheels 32, so that when the toy car is in a folded state, the two front wheels 22 can be folded back and located between the two rear wheels 32, which can also reduce the overall volume of the toy car after folding, making it convenient for users to store and carry.

[0074] See Figure 4 The front wheel assembly 2 has a higher support height than the rear wheel assembly 3. When the toy car is unfolded, the crossbeam 1 is tilted. When the crossbeam 1 is lifted under external force, the front wheel assembly 2 can automatically rotate and fold relative to the crossbeam 1 under gravity. Because the support height of the front wheel assembly 2 is greater than that of the rear wheel assembly 3, the center of gravity of the entire car is more biased towards the front. Therefore, during the folding process, when the user lifts the crossbeam 1 and removes the toy car from its supporting base, a larger rotational torque is generated on the side where the front wheel assembly 2 is located, forcing the front wheel assembly 2 to automatically rotate and fold towards the crossbeam 1, making the folding operation of the toy car simpler and less strenuous.

[0075] Optionally, when the toy car is folded, the front wheel assembly 2 rotates towards the second end 12 of the crossbeam 1, and the rear wheel assembly 3 rotates towards the first end 11 of the crossbeam 1, with both the front wheel assembly 2 and the rear wheel assembly 3 folded under the crossbeam 1. When the toy car is folded, the front wheel assembly 2 and the rear wheel assembly 3 can at least partially overlap; for example, the front wheel assembly 2 may be above or below the rear wheel assembly 3. Of course, the front wheel assembly 2 and the rear wheel assembly 3 may also not overlap.

[0076] In this embodiment, as Figure 5 As shown, in the folded state, the crossbeam 1, rear wheel assembly 3, and front wheel assembly 2 are arranged sequentially in the vertical direction, which can reduce the length and volume of the toy car after folding, making it easier to store and carry.

[0077] Optionally, see Figure 1 , Figure 2 and Figure 3 The front wheel assembly 2 includes a first bracket 21 and a front wheel 22 disposed on the first bracket 21. When the toy car is in a folded state, the rear wheel assembly 3 is folded between the first bracket 21 and the crossbeam 1, which can make full use of the space between the first bracket 21 and the crossbeam 1 and reduce the volume of the toy car after folding.

[0078] Optionally, the first support 21 includes a first connecting part 211 and a first wheel frame 214. When the toy car is in a folded state, the first connecting part 211 extends vertically, and the first wheel frame 214 is located below the crossbeam 1. A receiving space is formed between the first support 21 and the crossbeam 1, and the rear wheel assembly 3 is located within the receiving space. That is, folding the rear wheel assembly 3 does not increase the dimensions of the toy car in the height and width directions, thus making reasonable use of the space in the toy car's own structure and reducing the folded volume of the toy car.

[0079] Optionally, see Figure 1 , Figure 2 and Figure 5 The first bracket 21 has two front wheels 22 spaced apart, and the rear wheel assembly 3 is folded between the two front wheels 22. That is, when the toy car is in the folded state, the rear wheel assembly 3 can be located between the two front wheels 22, making full use of the space between the two front wheels 22 and further reducing the volume of the toy car after folding. The rear wheel assembly 3 may include one rear wheel 32 or two rear wheels 32.

[0080] See Figure 1 , Figure 2 and Figure 3 The front wheel assembly 2 includes a first support 21, and the rear wheel assembly 3 includes a second support 31. When the toy car is folded, the first support 21 and the second support 31 rotate and fold towards each other, forming a ring-shaped frame structure. That is, both the front wheel assembly 2 and the rear wheel assembly 3 rotate and fold under the crossbeam 1. When the toy car is folded, the first support 21 and the second support 31 form a frame structure, which can prevent the toy car from tipping to one side and further improve the support stability of the front wheel assembly 2 and the rear wheel assembly 3 for the toy car in the folded state.

[0081] Optionally, see Figure 2 and Figure 3The first support 21 includes a first crossbar 213 and two first wheel frames 214 spaced apart from the first crossbar 213. The front wheel assembly 2 also includes a front wheel 22, with the front wheel 22 rotatably mounted on the end of each first wheel frame 214 away from the first crossbar 213. The first crossbar 213 and the two first wheel frames 214 form an inverted U-shaped support frame, which can improve the overall torsional and bending strength of the first support 21, provide a stable mounting base for the front wheel 22, and provide stable support for the toy car, making the toy car ride smoothly.

[0082] Optionally, see Figure 2 The second support 31 includes a second crossbar 313 and two second wheel frames 314 spaced apart from the second crossbar 313. The rear wheel assembly 3 also includes a rear wheel 32, with the rear wheel 32 rotatably mounted on the end of each second wheel frame 314 away from the second crossbar 313. The second crossbar 313 and the two second wheel frames 314 form an inverted U-shaped support frame, which can improve the overall torsional and bending strength of the second support 31, provide a stable mounting base for the rear wheel 32, and provide stable support for the toy car, making the toy car ride smoothly.

[0083] In this embodiment, after the toy car is folded, the openings of the U-shaped first support 21 and the second support 31 face each other, forming an approximately rectangular frame structure that provides stable support for the toy car. In other embodiments, the specific structural shapes of the first support 21 and the second support 31 can be adaptively adjusted according to actual needs and are not limited to the U-shaped frame types listed above.

[0084] Optionally, the front wheel assembly 2 includes two front wheels 22, which are rotatably connected to two first wheel frames 214 in a one-to-one correspondence via a first wheel axle 24, providing stable support for the toy car. In other embodiments, the front wheel assembly 2 may also include a single front wheel 22 located between and rotatably connected to the two first wheel frames 214, allowing the toy car to be used as a two-wheeled or three-wheeled vehicle.

[0085] See Figure 1 , Figure 2 and Figure 3 The front wheel assembly 2 also includes a connecting shaft 25. Two front wheels 22 are spaced apart, and the two ends of the connecting shaft 25 are respectively connected to the first wheel axle 24 of the two front wheels 22. The connecting shaft 25 connects the two front wheels 22 together, which can make the left and right front wheels 22 rotate synchronously, improving the overall stability of the toy car.

[0086] Optionally, see Figure 2 and Figure 3The connecting shaft 25 extends in an S-shape, with a foot pedal 251 at each of the two bends of the S-shape, providing a foot position for the rider. Furthermore, stepping on the foot pedals 251 drives the connecting shaft 25 to rotate the two front wheels 22, thus moving the toy car.

[0087] Optionally, see Figure 2 The rear wheel 32 is rotatably connected to the second wheel frame 314 via the second wheel axle 33. The rear wheel 32 rotates around the second wheel axle 33 to enable the toy car to move. Furthermore, the second wheel frame 314 may include a fixed part and a rotating part that are rotatably connected. The fixed part is fixedly connected to the second crossbar 313, one end of the rotating part is rotatably connected to the fixed part, and the other end is equipped with the rear wheel 32. When the rotating part rotates relative to the fixed part, the rear wheel 32 can change its direction of travel.

[0088] For example, the rear wheel 32 is a swivel wheel, which allows the toy car to easily change direction, improving its flexibility and ease of operation. Furthermore, the swivel wheel design enables the toy car to automatically adjust its direction when moving forward or backward, reducing operational difficulty and enhancing ease of use.

[0089] In this embodiment, the rear wheel assembly 3 includes two rear wheels 32, which are rotatably connected to two second wheel frames 314 via second pivots 16, making the toy car move more smoothly. In other embodiments, the rear wheel assembly 3 may also include one rear wheel 32, and the front wheel assembly 2 may include one or two front wheels 22, so that the toy car can be used as a two-wheeled or three-wheeled vehicle.

[0090] See Figure 1 , Figure 2 and Figure 3 The front wheel assembly 2 includes a first bracket 21, and the rear wheel assembly 3 includes a second bracket 31. The first end 11 of the crossbeam 1 is rotatably connected to the first bracket 21, and the second end 12 of the crossbeam 1 is rotatably connected to the second bracket 31, so as to realize the rotatable connection between the front wheel assembly 2 and the rear wheel assembly 3 and the crossbeam 1, which facilitates the folding and unfolding of the toy car. Optionally, the first end 11 of the crossbeam 1 is provided with a first joint head 13, the first bracket 21 is provided with a first connecting part 211, and a second joint head 212 is provided on the first connecting part 211. The first joint head 13 and the second joint head 212 are rotatably connected around a first axis.

[0091] Specifically, in combination Figure 8 and Figure 9 The first joint head 13 and the second joint head 212 are rotatably connected by a first rotating shaft 15. The first joint head 13 is provided with a first shaft hole, and the second joint head 212 is provided with a second shaft hole. The first rotating shaft 15 passes through the first shaft hole and the second shaft hole to realize the rotatable connection between the first joint head 13 and the second joint head 212.

[0092] Optionally, a first limiting structure is provided between the first joint head 13 and the second joint head 212. The first limiting structure is used to limit the relative rotation angle of the first joint head 13 and the second joint head 212, so that the first joint head 13 and the second joint head 212 can rotate relative to each other within a limited range, ensuring that the front wheel assembly 2 can only switch between the folded state and the unfolded state relative to the crossbeam 1, and cannot rotate arbitrarily relative to the crossbeam 1.

[0093] See Figure 7 and Figure 8 The first limiting structure includes a limiting protrusion 2122 and a limiting groove 132. The limiting groove 132 extends in an arc shape with the corresponding first axis as its center. The limiting protrusion 2122 slides in engagement with the limiting groove 132, and the limiting protrusion 2122 can stop at one end of the limiting groove 132 in its extending direction. (Refer to...) Figure 7 and Figure 8 When the limiting protrusion 2122 stops at the upper end of the limiting slide groove 132, it indicates that the front wheel assembly 2 has been fully extended forward and can no longer rotate relative to the crossbeam 1. When the limiting protrusion 2122 stops at the lower end of the limiting slide groove 132, it indicates that the front wheel assembly 2 has been fully folded backward. The cooperation between the limiting protrusion 2122 and the limiting slide groove 132 allows the front wheel assembly 2 to accurately switch between the folded and extended states, preventing the front wheel assembly 2 from overtraveling relative to the crossbeam 1.

[0094] In this embodiment, the first joint head 13 is provided with the aforementioned limiting groove 132, and the second joint head 212 is provided with the aforementioned limiting protrusion 2122. In other embodiments, the limiting protrusion 2122 may also be provided on the first joint head 13, and the limiting groove 132 may be provided on the second joint head 212.

[0095] See Figure 7 and Figure 8 The first joint head 13 is provided with a first fixing part 131, which at least partially overlaps with the first end 11 of the crossbeam 1 and is detachably fixedly connected to the crossbeam 1. Designing the first fixing part 131 to be detachably connected to the crossbeam 1 facilitates the assembly of the front wheel assembly 2 and the crossbeam 1, enabling modular production. Designing the first fixing part 131 to overlap with the first end 11 of the crossbeam 1 increases the connection stability between the crossbeam 1 and the first joint head 13, while also strengthening the load-bearing capacity of the crossbeam 1 at the rotating joint and preventing deformation and damage to the crossbeam 1.

[0096] For example, the first fixing part 131 is a solid structure, and the first end 11 of the crossbeam 1 is a hollow structure. The first fixing part 131 is inserted into the crossbeam 1 and is fixedly connected together by fasteners such as bolts or screws, so that there are no extra parts on the outside of the crossbeam 1 and the appearance is neater and more beautiful.

[0097] In other embodiments, the first fixing part 131 may be omitted, and the first joint head 13 may be directly integrally formed with the crossbeam 1. The crossbeam 1 may be made of high-strength material (such as high-strength alloy or composite material) to ensure the load-bearing strength of the crossbeam 1, while reducing the overall weight of the toy car.

[0098] Optionally, see Figure 7 and Figure 8 The second joint head 212 is provided with a second fixing part 2121, which is detachably fixed to the first connecting part 211. Designing the second fixing part 2121 to be detachably connected to the first connecting part 211 facilitates modular production and subsequent assembly.

[0099] For example, both the first connecting part 211 and the second fixing part 2121 are tubular structures. The first connecting part 211 is inserted into the cavity of the second fixing part 2121 and is fixedly connected by fasteners such as screws. The way in which the first connecting part 211 and the second fixing part 2121 are sleeved and inserted can increase the connection strength between the two and improve the load-bearing capacity of the first bracket 21.

[0100] See Figure 6 , Figure 7 and Figure 8 A first locking member 7, movable along a first axis (the axis of the first rotating shaft 15), is provided between the first joint head 13 and the second joint head 212. When the toy car is in an unfolded state and / or a folded state, the first locking member 7 locks the first joint head 13 and the second joint head 212 to restrict relative rotation between the first joint head 13 and the second joint head 212. In this embodiment, as shown... Figure 7 and Figure 8 As shown, when the toy car is in the unfolded state, the first locking member 7 is in the position of locking the first joint head 13 and the second joint head 212, ensuring that the toy car remains stably in the unfolded state and can be used normally. When the toy car is in the folded state, the first locking member 7 switches back to the position of locking the first joint head 13 and the second joint head 212, so that the toy car remains stably in the folded state.

[0101] Specifically, see Figure 6 , Figure 7 and Figure 8 The first joint head 13 is provided with a first locking groove 133, and the second joint head 212 is provided with a second locking groove (not shown). When the first locking member 7 is engaged with both the first locking groove 133 and the second locking groove, the first joint head 13 and the second joint head 212 are locked. When the first locking member 7 moves along the first axis direction to disengage from the first locking groove 133 and engage with the second locking groove, the first joint head 13 and the second joint head 212 are unlocked, and the first joint head 13 and the second joint head 212 can rotate relative to each other.

[0102] In this embodiment, the first locking member 7 has two first limiting teeth 71 spaced apart circumferentially, the first joint head 13 has three first locking grooves 133 spaced apart circumferentially, and the second joint head 212 has second locking grooves corresponding one-to-one with the two first limiting teeth 71. (Refer to...) Figure 8 When the front wheel assembly 2 is in the unfolded state, the two first limiting teeth 71 engage with the two second locking grooves one-to-one, and simultaneously, the two first limiting teeth 71 engage with the two first locking grooves 133 below the first joint head 13. When it is necessary to fold the front wheel assembly 2, firstly, the first locking member 7 is moved along the first axis direction to disengage from the first locking groove 133, thereby unlocking the first joint head 13 from the second joint head 212. Then, the front wheel assembly 2 is rotated relative to the crossbeam 1 until the limiting protrusion 2122 stops at the position. Figure 6 When the front wheel assembly 2 is folded into place at the lower end of the middle limit slide groove 132, the two first limit teeth 71 of the first locking member 7 can engage with the two first locking grooves 133 above the first joint head 13 to lock the first joint head 13 and the third joint head 14, so that the front wheel assembly 2 is stably kept in the folded state.

[0103] Optionally, a first unlocking member can be provided between the first joint head 13 and the first locking member 7. The first unlocking member can rotate around a first axis and move along the direction of the first axis. One of the first unlocking member and the first joint head 13 is provided with a guide protrusion, and the other is provided with a guide groove. When the first unlocking member is driven to rotate, the guide protrusion slides with the guide groove and generates an axial driving force on the first unlocking member, causing the first unlocking member to push against the first locking member 7 and move along the direction of the first axis to disengage from the first locking groove 133. An operating part can be provided on the crossbeam 1 or the front wheel assembly 2, and the operating part is connected to the first unlocking member via a traction cable. By pulling the traction cable through the operating part, the first unlocking member is rotated, thereby driving the first locking member 7 to move axially and unlock.

[0104] Furthermore, a first elastic element can be provided between the first locking member 7 and the second joint head 212. During the process of the first locking member 7 disengaging from the first locking groove 133, the first elastic element is compressed, causing it to store energy. When the force of the traction cable on the first unlocking member is removed, the first locking member 7 can move in the opposite direction under the elastic force of the first elastic element, causing the first locking member 7 to simultaneously engage with the first locking groove 133 and the second locking groove, locking the first joint head 13 and the second joint head 212. For example, the first elastic element can be a spring.

[0105] See Figure 2 and Figure 3The second end 12 of the crossbeam 1 is provided with a third joint head 14, the second bracket 31 is provided with a second connecting part 311, and a fourth joint head 312 is provided on the second connecting part 311. The third joint head 14 and the fourth joint head 312 are rotatably connected around a second axis. That is, the rear wheel assembly 3 folds or unfolds relative to the crossbeam 1 by rotation, making the folding and unfolding operation of the toy car more convenient.

[0106] Specifically, in combination Figure 7 and Figure 9 The third joint head 14 and the fourth joint head 312 are rotatably connected by the second rotating shaft 16. The third joint head 14 is provided with a third shaft hole, and the fourth joint head 312 is provided with a fourth shaft hole. The second rotating shaft 16 passes through the third shaft hole and the fourth shaft hole to realize the rotatable connection between the third joint head 14 and the fourth joint head 312.

[0107] Optionally, a second limiting structure is provided between the third joint head 14 and the fourth joint head 312. The second limiting structure is used to limit the relative rotation angle between the third joint head 14 and the fourth joint head 312, so that the third joint head 14 and the fourth joint head 312 can rotate relative to each other within a limited range, ensuring that the rear wheel assembly 3 can only switch between the folded state and the unfolded state relative to the crossbeam 1, and cannot rotate arbitrarily relative to the crossbeam 1.

[0108] Specifically, see Figure 6 , Figure 7 and Figure 9 The second limiting structure also includes a limiting protrusion 2122 and a limiting groove 132. The limiting groove 132 extends in an arc shape with the corresponding second axis (the axis of the second rotating shaft 16) as its center. The limiting protrusion 2122 slides in engagement with the limiting groove 132, and the limiting protrusion 2122 can stop at one end of the limiting groove 132 in its extending direction. (Refer to...) Figure 7 and Figure 9 When the limiting protrusion 2122 stops at the upper end of the limiting slide groove 132, it indicates that the rear wheel assembly 3 has been fully extended rearward and can no longer rotate relative to the crossbeam 1. When the limiting protrusion 2122 stops at the lower end of the limiting slide groove 132, it indicates that the rear wheel assembly 3 has been fully folded forward. The cooperation between the limiting protrusion 2122 and the limiting slide groove 132 allows the rear wheel assembly 3 to accurately switch between the folded and extended states, preventing the rear wheel assembly 3 from overtraveling relative to the crossbeam 1.

[0109] In this embodiment, the third joint head 14 is provided with the aforementioned limiting protrusion 2122, and the fourth joint head 312 is provided with the aforementioned limiting groove 132. In other embodiments, the limiting protrusion 2122 may also be provided on the fourth joint head 312, and the limiting groove 132 may be provided on the third joint head 14.

[0110] See Figure 7 and Figure 9 The third joint head 14 is provided with a third fixing part 141, which at least partially overlaps with the second end 12 of the crossbeam 1 and is detachably fixedly connected to the crossbeam 1. Designing the third fixing part 141 to be detachably connected to the crossbeam 1 facilitates the assembly of the rear wheel assembly 3 and the crossbeam 1, enabling modular production. Designing the third fixing part 141 to overlap with the second end 12 of the crossbeam 1 increases the connection stability between the crossbeam 1 and the third joint head 14, while also strengthening the load-bearing capacity of the crossbeam 1 at the rotating joint.

[0111] For example, the third fixing part 141 is a solid structure, and the second end 12 of the crossbeam 1 is a hollow structure. The third fixing part 141 is inserted into the crossbeam 1 and is fixedly connected together by fasteners such as bolts or screws, so that there are no extra parts on the outside of the crossbeam 1, and the appearance is neater and more beautiful.

[0112] In other embodiments, the third fixing part 141 may be omitted, and the third joint head 14 may be directly integrally formed with the crossbeam 1. The crossbeam 1 may be made of high-strength material (such as high-strength alloy or composite material) to ensure the load-bearing strength of the crossbeam 1, while reducing the overall weight of the toy car.

[0113] See Figure 7 and Figure 9 The fourth joint head 312 is provided with a fourth fixing part 3121, which is detachably fixed to the second connecting part 311. Designing the fourth fixing part 3121 to be detachably connected to the second connecting part 311 facilitates modular production and subsequent assembly.

[0114] For example, the fourth fixing part 3121 is a solid structure, and the second connecting part 311 is a tubular structure. The fourth fixing part 3121 is inserted into the cavity of the second connecting part 311 and is fixedly connected by fasteners such as screws. The way in which the second connecting part 311 and the fourth fixing part 3121 are sleeved and inserted can increase the connection strength between the two and improve the load-bearing capacity of the second bracket 31.

[0115] See Figure 6 , Figure 7 and Figure 9 A second locking member 8, movable along the second axis (the axis of the second rotating shaft 16), is provided between the third joint head 14 and the fourth joint head 312. When the toy car is in the unfolded state and / or folded state, the second locking member 8 locks the third joint head 14 and the fourth joint head 312 to restrict relative rotation between them. In this embodiment, as shown... Figure 6 and Figure 7As shown, when the toy car is in the unfolded state, the second locking member 8 is in the position of locking the third joint head 14 and the fourth joint head 312, ensuring that the toy car remains stably in the unfolded state and can be used normally. When the toy car is in the folded state, the second locking member 8 switches back to the position of locking the third joint head 14 and the fourth joint head 312, so that the toy car remains stably in the folded state.

[0116] Specifically, see Figure 6 , Figure 7 and Figure 9 The third joint head 14 is provided with a third locking groove 142, and the fourth joint head 312 is provided with a fourth locking groove 3122. When the second locking member 8 is engaged with both the third locking groove 142 and the fourth locking groove 3122, the third joint head 14 and the fourth joint head 312 are locked. When the second locking member 8 moves along the second axis direction, disengages from the fourth locking groove 3122 and engages with the third locking groove 142, the third joint head 14 and the fourth joint head 312 are unlocked, and the two can rotate relative to each other.

[0117] In this embodiment, the second locking member 8 has a protruding second limiting tooth 81, the third joint head 14 has a third locking groove 142 that engages with the second limiting tooth 81, and the fourth joint head 312 has two fourth locking grooves 3122 spaced apart circumferentially. (Refer to...) Figure 6 and Figure 9 When the rear wheel assembly 3 is in the unfolded state, the second limiting tooth 81 simultaneously engages with the third locking groove 142 and a fourth locking groove 3122 below the fourth joint head 312. When it is necessary to fold the rear wheel assembly 3, firstly, the second locking member 8 is moved along the second axis direction to disengage from the fourth locking groove 3122, thereby unlocking the third joint head 14 and the fourth joint head 312. Then, the rear wheel assembly 3 is rotated relative to the crossbeam 1 until the limiting protrusion 2122 stops at the position. Figure 9 When the lower end of the middle limit slide groove 132 is reached, the rear wheel assembly 3 is folded into place. At this time, the second limit tooth 81 of the second locking member 8 can engage with a fourth locking groove 3122 above the fourth joint head 312 to lock the third joint head 14 and the fourth joint head 312, so that the rear wheel assembly 3 is stably kept in the folded state.

[0118] Optionally, a second unlocking member can be provided between the fourth joint head 312 and the second locking member 8. The second unlocking member can rotate around the second axis and move along the direction of the second axis. One of the second unlocking member and the fourth joint head 312 is provided with a guide protrusion, and the other is provided with a guide groove. When the second unlocking member is driven to rotate, the guide protrusion slides with the guide groove and generates an axial driving force on the second unlocking member, causing the second unlocking member to push the second locking member 8 to move along the direction of the second axis and disengage from the fourth locking groove 3122. An operating part can be provided on the crossbeam 1 or the rear wheel assembly 3, and the operating part is connected to the second unlocking member via a traction cable. By pulling the traction cable through the operating part, the second unlocking member is rotated, thereby driving the second locking member 8 to move axially and unlock.

[0119] Furthermore, a second elastic element can be provided between the second locking member 8 and the third joint head 14. During the process of the second locking member 8 disengaging from the fourth locking groove 3122, the second elastic element is compressed, causing it to store energy. When the force of the traction cable on the second unlocking member is removed, the second locking member 8 can move in the opposite direction under the elastic force of the second elastic element, causing the second locking member 8 to simultaneously engage with both the third locking groove 142 and the fourth locking groove 3122, locking the third joint head 14 and the fourth joint head 312. For example, the second elastic element can be a spring.

[0120] See Figure 1 and Figure 2 The toy car also includes a handle assembly 5, which is connected to the front wheel assembly 2 and / or the crossbeam 1. In this embodiment, the handle assembly 5 is a steering wheel, which is connected to the first bracket 21 via a steering shaft. The driving direction of the front wheel 22 can be adjusted by the steering wheel.

[0121] See Figure 1 , Figure 2 and Figure 3 The toy car also includes a seat 6, which is mounted on the crossbeam 1 and provides a seat for the rider. In this embodiment, the seat 6 is provided with a mounting part 61, which is fixed to the crossbeam 1 by fasteners such as bolts or screws.

[0122] For example, the mounting part 61 is a tubular structure that can be fitted and fixed to the outside of the measuring device to improve the installation stability of the stool 6.

[0123] The folding and unfolding process of the toy car provided in this embodiment is as follows:

[0124] like Figure 4As shown, the toy car is currently in the unfolded state. When the toy car needs to be folded, first unlock the first locking piece 7 to lock the first joint head 13 and the second joint head 212. At the same time, the second locking piece 8 can be unlocked to lock the third joint head 14 and the fourth joint head 312. Then lift the crossbeam 1, and the front wheel assembly 2 will automatically rotate backward. Operate the rear wheel assembly 3 to rotate forward, so that the rear wheel assembly 3 rotates towards the crossbeam 1 and is stored between the two front wheels 22 of the front wheel assembly 2, as shown. Figure 5 The state is shown. During this process, the first joint head 13 and the second joint head 212 rotate relative to each other around the first axis 15, and the third joint head 14 and the fourth joint head 312 rotate relative to each other around the second axis 16.

[0125] When the toy car needs to be unfolded, operate the front wheel assembly 2 to rotate forward and unfold it as shown. Figure 4 As shown, after operation, the rear wheel assembly 3 rotates backward and unfolds to the position shown. Figure 4 The state shown is sufficient.

[0126] Example 2

[0127] like Figure 10 , Figure 11 and Figure 12 As shown, this embodiment provides a toy car, which differs from Embodiment 1 in that:

[0128] See Figure 10 and Figure 11 The front wheel assembly 2 includes a first bracket 21 and two front wheels 22 spaced apart from the first bracket 21. The toy car also includes a decorative piece 4 disposed on the first bracket 21. The decorative piece 4 has a support protrusion 41. When the toy car is folded, the support protrusion 41 and the two front wheels 22 are all supported on the support base, and the support protrusion 41 and the two front wheels 22 are triangularly distributed. That is, after the toy car is folded, the support protrusion 41 on the decorative piece 4 faces the support base, and the support protrusion 41 and the two front wheels 22 contact the support base, forming a three-point support, which can more stably support the toy car in the folded state and ensure the stability of the toy car after folding. The support base can be the ground, a table, etc.

[0129] In some embodiments, the front wheel assembly 2 may also include a front wheel 22, and the first bracket 21 has two support ends. The two support ends and the front wheel 22 form a triangle, so that the toy car can form a three-point support after folding, thereby improving the placement stability of the toy car.

[0130] Optionally, the decorative element 4 also includes a toy windmill 42 disposed on the first support 21, which can rotate relative to the first support 21 to enhance the fun of the toy car.

[0131] Furthermore, such as Figure 12As shown, the height of the support protrusion 41 is greater than the height of the toy windmill 42 relative to the first bracket 21, so that when the toy car is folded, the support protrusion 41 contacts the support base, while the toy windmill 42 does not contact the support base, thus avoiding damage to the toy windmill 42 due to force.

[0132] In other embodiments, the decorative element 4 can be changed to different styles according to design requirements, and is not limited to the forms listed in this embodiment.

[0133] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
