Description

Technical Field

[0002] A toy shopping cart is a common children's toy. Its structure typically includes a cart body and wheels located at the bottom of the cart body, with compartments formed on the cart body for holding items. When playing, children can place toys, items, etc., into the compartments and push the toy shopping cart to move it.

[0003] However, existing toy shopping carts still have the following shortcomings: First, toy shopping carts need to be pushed manually, making them inconvenient to use. Second, in terms of movement, toy shopping carts can usually only move in a straight line and do not have a turning function; when a turn is needed, the user must manually position the shopping cart to face the direction.

[0050] Figure 1 and Figure 2 The present invention illustrates a remote-controlled toy shopping cart 10 in some embodiments, which includes a support device 1, a drive device 2, a carrying device 3, and a remote control device 4.

[0051] It should be noted that the drive unit 2 is mounted on the support unit 1, which supports both the drive unit 2 and the carrying device 3. The drive unit 2, when powered on, drives the support unit 1 to selectively perform movement and / or steering functions. The carrying device 3 is connected to the support unit 1 and serves to load items; its inclusion also enhances the realism of the product. The remote control device 4 is communicatively connected to the support unit 1, allowing the user to remotely control the drive unit 2.

[0052] like Figures 1 to 9 As shown, the support device 1 includes a frame 11, a control circuit board 12, and several rotating wheels 13. The control circuit board 12 is mounted on the frame 11, and each rotating wheel 13 is connected to the frame 11. The cargo-carrying device 3 is mounted on the frame 11.

[0053] The drive unit 2 includes a drive assembly 21, a moving transmission structure 22, and a steering transmission structure 23. The drive assembly 21 is mounted on the frame 11 and is electrically connected to the control circuit board 12. The drive assembly 21 is drivenly connected to the moving transmission structure 22 and the steering transmission structure 23 respectively. The moving transmission structure 22 is connected to at least a portion of the rotating wheels 13, and the steering transmission structure 23 is connected to at least a portion of the rotating wheels 13. The drive assembly 21 is configured to output torque to the moving transmission structure 22 and the steering transmission structure 23 when energized.

[0054] like Figure 10 As shown, the remote control device 4 includes a housing 41, a remote control circuit board, and a control key 42. The remote control circuit board is disposed inside the housing 41, and the control key 42 is movably disposed on the housing 41. The control key 42 is electrically connected to the remote control circuit board, and the remote control circuit board is communicatively connected to the control circuit board 12.

[0055] The movable transmission structure 22 is used to drive at least part of the rotating wheel 13 to rotate around the wheel shaft 131 after receiving torque.

[0056] The steering transmission structure 23 is used to drive the wheel axle 131 of at least part of the rotating wheel 13 to rotate after receiving torque, so that the wheel axle 131 drives the rotating wheel 13 to turn.

[0057] Understandably, the frame 11 provides mounting positions for other components, thus determining the connection and positional relationships between them. The control circuit board 12 is equipped with corresponding control circuits and circuit function modules—such as a communication circuit module for remote communication with the remote control device 4. The rotating wheels 13 support the movement of the frame 11. It should be noted that the number of rotating wheels 13 can be flexibly set, and the rotating wheels 13 can be configured to be directly or indirectly connected to the frame 11.

[0058] The drive assembly 21 can be configured as a component capable of outputting torque when energized, as is common in the art. The torque output by the drive assembly 21 can be transmitted to the moving transmission structure 22 and the steering transmission structure 23 respectively. After being transmitted via the moving transmission structure 22, the torque drives the correspondingly connected rotating wheel 13 to rotate around the wheel axle 131, that is, the rotating wheel 13 will rotate around the central axis of the wheel axle 131 in the length direction, thereby enabling the product to perform a moving function; while after being transmitted via the steering transmission structure 23, the torque drives the wheel axle 131 of the correspondingly connected rotating wheel 13 to rotate, but at this time the rotation of the wheel axle 131 will drive the correspondingly connected rotating wheel 13 to rotate towards different positions, thereby enabling the product to perform a steering function. Furthermore, during the movement, the frame 11 will drive the loading device 3 mounted on it to move together.

[0059] In the remote control device 4, the housing 41 protects the remote control circuit board (not shown in the diagram) and the control key 42. The remote control circuit board sends a corresponding control signal to the control circuit board 12 when the control key 42 is triggered. The control circuit board 12 then controls the corresponding part of the drive device 2 to operate according to the control signal. Of course, if the support device 1 also has electrical components other than the drive device 2, these components can be further configured to be remotely controlled via the remote control device 4, such as sound functions, light functions, and other common functions found on remote-controlled vehicles in the prior art.

[0060] It should be noted that the aforementioned "moving transmission structure 22 is connected to at least a portion of the rotating wheels 13, and steering transmission structure 23 is connected to at least a portion of the rotating wheels 13" means that a portion of the rotating wheels 13 are indirectly connected to the frame 11 through the moving transmission structure 22, and a portion of the rotating wheels 13 are indirectly connected to the frame 11 through the steering transmission structure 23.

[0061] Furthermore, in some embodiments, the rotating wheel 13 of the same part can be configured to be connected to the moving transmission structure 22 on one hand, and the rotating wheel 13 of the same part can also be configured to be connected to the steering transmission structure 23 on the other hand, that is, the rotating wheel 13 of the same part can perform moving and steering functions.

[0062] Furthermore, in other embodiments, some of the rotating wheels 13 can be configured to be connected to the moving transmission structure 22, while other rotating wheels 13 can be configured to be connected to the steering transmission structure 23. That is, different parts of the rotating wheels 13 will perform the moving and steering functions respectively. In actual design and production, manufacturers can flexibly adopt different implementation methods according to different design and usage requirements.

[0063] It should also be noted that the shape, size, and connection method of the cargo carrier 3 to the frame 11 can be flexibly set. The connection methods include, but are not limited to, plug-in, snap-in, screw-in, magnetic connection, strap connection, and other common connection methods.

[0064] In some embodiments of the remote-controlled toy shopping cart 10, the drive assembly 21 includes a drive motor (not shown), the output shaft of which drives the moving transmission structure 22 and the steering transmission structure 23 respectively.

[0065] It should be noted that in this type of embodiment, both movement and steering functions can be achieved using a single drive motor. Specifically, this structure, which uses a single drive motor and achieves corresponding torque distribution, includes at least the following implementation methods:

[0066] Firstly, the torque output by the drive motor can be distributed via a gear switching structure commonly used in the prior art: the gear switching structure is equipped with a movable switching gear. When the switching gear moves to different positions, it meshes with the input end of the moving transmission structure 22 or the input end of the steering transmission structure 23 respectively. The torque output by the drive motor is then transmitted to the moving transmission structure 22 or the steering transmission structure 23 accordingly, thereby allowing the product to switch between moving and steering functions.

[0067] Secondly, the torque output by the drive motor can be distributed through a cam distribution structure commonly used in the prior art: the cam in the cam distribution structure rotates synchronously with the output shaft of the drive motor, and the profile surface of the cam engages with the moving transmission structure 22 and the steering transmission structure 23 in sequence during the rotation process, so the torque output by the drive motor is distributed to the moving transmission structure 22 and the steering transmission structure 23 in sequence.

[0068] Third, the torque output by the drive motor can be distributed through a clutch switching structure commonly used in existing technologies: when the clutch in the clutch switching structure is engaged, the torque output by the drive motor is transmitted to the corresponding transmission structure; when the clutch is disengaged, the torque transmission path is interrupted. The object to which the torque is transmitted can be selected by whether the clutch is engaged with the moving transmission structure 22 or the steering transmission structure 23.

[0069] In some embodiments of the remote-controlled toy shopping cart 10, one of the rotating wheels includes a swivel wheel. A drive assembly is driven to the swivel wheel via a moving transmission structure and a steering transmission structure. The moving transmission structure is used to receive the torque output by the drive assembly and drive the swivel wheel to rotate around a first rotation axis. The steering transmission structure is used to receive the torque output by the drive assembly and drive the swivel wheel to rotate around a second rotation axis. The first rotation axis and the second rotation axis intersect.

[0070] Understandably, the casters used in this type of embodiment are spherical. During actual operation, when the moving transmission structure 22 drives the caster to rotate around the first rotation axis, relative rolling occurs between the caster and the supporting surface. The rotation of the caster itself is converted into displacement of the product as a whole relative to the supporting surface, and the product performs a moving function. When the steering transmission structure 23 drives the caster to rotate around the second rotation axis, the rolling direction corresponding to the caster's rolling around the first rotation axis changes accordingly, and the product performs a steering function. It should be noted that using the content of this type of embodiment can reduce the required number of casters; furthermore, the technical solutions used in this type of embodiment are disclosed and applied in the prior art, therefore no corresponding drawings are provided, but the structure is clear to those skilled in the art.

[0071] like Figures 5 to 9 As shown, in some embodiments of the remote-controlled toy shopping cart 10, the drive assembly 21 includes a moving motor 212 and a steering motor 213;

[0072] The mobile motor 212 is mounted on the frame 11, and the mobile motor 212 is driven and connected to the mobile transmission structure 22, which is driven and connected to a portion of the wheel axles 131.

[0073] Steering motor 213 is mounted on frame 11 and is driven by steering transmission structure 23, which is driven by another part of wheel axle 131.

[0074] The mobile motor 212 is configured to output torque to the mobile transmission structure 22 when it is powered on, thereby driving the wheel axle 131 to rotate, and thus a portion of the rotating wheel 13 rotates around the wheel axle 131.

[0075] The steering motor 213 is configured to output torque to the steering transmission structure 23 when it is powered on, so that the steering transmission structure 23 drives the rotating wheel 13 to turn through the wheel axle 131.

[0076] Understandably, the moving motor 212 is dedicated to providing the power required for the moving function, and the steering motor 213 is dedicated to providing the power for the steering function. The energizing status of the two motors can be controlled separately. When the user needs the product to move, the moving motor 212 is energized, and the product performs the moving function; when the user needs the product to turn, the steering motor 213 is energized, and the product performs the steering function; when both the moving motor 212 and the steering motor 213 are energized, the moving and steering functions are performed simultaneously.

[0077] It should be noted that, in the embodiments of this type, the power sources for the product's movement function and steering function are independent of each other, and the two can be controlled independently and executed simultaneously, thereby improving the product's operational flexibility.

[0078] like Figures 5 to 8 As shown, in some embodiments of the remote-controlled toy shopping cart 10, the moving transmission structure 22 includes a gearbox 221, which is mounted on the frame 11, and the moving motor 212 is driven by the gearbox 221 to be connected to at least two axles 131.

[0079] Understandably, gearbox 221 is used for torque transmission between the movable motor 212 and at least two axles 131. The torque output by the movable motor 212 is transmitted through gearbox 221 and distributed to at least two axles 131, thereby enabling a single movable motor 212 to synchronously drive at least two axles 131. The torque transmission within gearbox 221 also has the effect of speed reduction and torque amplification.

[0080] It should be noted that, by adopting the content of this embodiment, the torque output by the mobile motor 212 can be output to the corresponding wheel axle 131 at a fixed transmission ratio through the setting of the gearbox 221, thus ensuring the stability of power output during movement.

[0081] Furthermore, in some embodiments, the gearbox 221 may be configured to include a plurality of gears, which mesh sequentially, with one gear being driven by the movable motor 212 and the other gear being fixedly mounted on the axle 131. Even further, the two axles 131 may be configured to be interconnected and integrally formed, so that by fixing a single gear onto the axle 131, the movable motor 212 can simultaneously drive the two rotating wheels to rotate synchronously via the integrally formed axle.

[0082] like Figures 5 to 9As shown, in some embodiments of the remote-controlled toy shopping cart 10, the steering transmission structure 23 includes a first steering gear 231, a second steering gear 232, a slider 233, and a swing arm 234. The steering motor 213 is driven and connected to the first steering gear 231. The second steering gear 232 is rotatably mounted on the frame 11. The first steering gear 231 and the second steering gear 232 mesh with each other. The slider 233 is slidably mounted on the frame 11 and is slidably engaged with the second steering gear 232. The swing arm 234 is rotatably connected to the frame 11 and the slider 233, respectively, and is connected to a portion of the axle 131.

[0083] Understandably, the torque output by the steering motor 213 is transmitted to the second steering gear 232 via the first steering gear 231, causing the second steering gear 232 to rotate under the influence of the first steering gear 231. Subsequently, the rotational motion of the second steering gear 232 is converted into linear sliding of the sliding member 233 relative to the frame 11 through its sliding engagement with the sliding member 233. The sliding member 233 thus converts rotational motion into linear motion and outputs it to the swing arm 234. Driven by the sliding member 233, the swing arm 234 swings at its rotational connection with the frame 11. When the swing arm 234 swings, it causes the axle 131 connected to it to move and change direction. The axle 131 then drives the corresponding rotating wheel 13 to steer. When the steering motor 213 outputs torque in different directions, the sliding member 233 slides in the corresponding directions, and the swing arm 234 swings in the corresponding directions, thus enabling the product to achieve the function of steering in different directions.

[0084] It should be noted that in this type of embodiment, the torque output by the steering motor 213 is converted into the required motion (that is, into the oscillation of the wheel axle 131) through gear meshing and sliding engagement, making the steering motion more stable and reliable.

[0085] like Figure 9 As shown, in some embodiments of the remote-controlled toy shopping cart 10, a connecting arm 2331 is provided on the slider 233, and a connecting waist hole 2322 is provided on the second steering gear 232. The connecting arm 2331 passes through the connecting waist hole 2322, and the connecting arm 2331 slides in cooperation with the connecting waist hole 2322.

[0086] Understandably, when the second steering gear 232 rotates, the connecting waist hole 2322 rotates together with the second steering gear 232. The hole wall of the connecting waist hole 2322 and the connecting arm 2331 abut against each other. Since the sliding member 233 is guided by the frame 11, it can only slide linearly in a predetermined direction. While the connecting arm 2331 moves relative to the connecting waist hole 2322 as the sliding member 233 moves, the rotational motion of the second steering gear 232 can be converted into the linear sliding of the sliding member 233.

[0087] It should be noted that in this embodiment, the conversion between rotary motion and linear sliding is achieved simply by sliding the connecting arm 2331 through the connecting waist hole 2322. The structure is simple and the sliding cooperation is smoother, which improves the stability and smoothness of the steering action.

[0088] In some other embodiments of the remote-controlled toy shopping cart 10, the slider 233 is provided with a connecting waist hole, and the second steering gear 232 is provided with a connecting arm, which passes through the connecting waist hole and slides in cooperation.

[0089] Understandably, the difference between this embodiment and the previous embodiments lies in the interchange of the positions of the connecting waist hole and the connecting arm. However, it should be noted that, using the content of this embodiment, the rotation of the second steering gear 232 can also be converted into the sliding motion of the sliding member 233, thereby also improving the steering stability and smoothness of the product.

[0090] like Figure 7 and Figure 9 As shown, in some embodiments of the remote-controlled toy shopping cart 10, the second steering gear 232 includes a sector gear.

[0091] Understandably, in this embodiment, a sector gear is used as the second steering gear 232. The sector gear can meet the swing angle required for the product's steering within a limited space, avoiding the excessive space occupied by common complete circular gears and improving structural compactness. Furthermore, the sector gear also has the advantage of being lightweight, reducing the overall weight of the product to a certain extent.

[0092] like Figure 7 and Figure 8 As shown, in some embodiments of the remote-controlled toy shopping cart 10, the steering transmission structure 23 includes two swing arms 234, each swing arm 234 having an extension 2341. The two swing arms 234 are rotatably mounted on the frame 11. One end of the sliding member 233 is rotatably connected to one of the extensions 2341, and the other end of the sliding member 233 is rotatably connected to the other extension 2341. The two swing arms 234 are connected to the two axles 131 in a one-to-one correspondence.

[0093] Understandably, the extension 2341 is a connection part on the swing arm 234 for the sliding member 233 to rotate and connect. The extension 2341 extends outward from the swing center of the swing arm 234, and the position where it is rotatably connected to the sliding member 233 maintains a distance from the swing center of the swing arm 234. The linear sliding of the sliding member 233 is converted into the swing motion of the swing arm 234 through this distance.

[0094] When the slider 233 slides, one end of the slider 233 pushes one of the extensions 2341, and the other end pulls the other extension 2341 simultaneously. The two swing arms 234 are driven by the slider 233 to swing around their respective rotational connection points with the frame 11, and drive the two wheel axles 131 to change their orientation accordingly. The rotating wheels 13 corresponding to the two wheel axles 131 thus deflect synchronously, and the product achieves steering.

[0095] It should be noted that the linear sliding of the slider 233 can synchronously drive the two swing arms 234 to rotate, and the two wheel axles 131 and the corresponding rotating wheels 13 to rotate synchronously, resulting in good consistency of steering action and providing reliability of steering motion.

[0096] like Figures 3 to 6 As shown, in some embodiments of the remote-controlled toy shopping cart 10, the carrying device 3 includes a carrying frame 31, and a carrying position 111 is provided on the frame 11, with the carrying frame 31 disposed on the carrying position 111.

[0097] Understandably, the frame of the carrying frame 31 encloses and forms a storage space for placing items.
