Description

Technical Field

[0001] This invention relates to the field of toy technology, specifically to a simulated toy sanitation vehicle with linked unloading and dual-mode bucket hanging functions. Background Technology

[0002] Simulated sanitation vehicle toys are important educational toys for children to learn about urban sanitation operations and cultivate environmental awareness, and there is a wide market demand for them. Existing similar toys generally have the following shortcomings: 1. The tipping and unloading of the vehicle and the opening and closing of the loading port cover require separate operation, resulting in fragmented actions, poor continuity, and insufficient simulation experience; 2. The garbage can's hanging structure is simple, making it easy to shake and fall off during movement, and the tipping angle during unloading is insufficient, failing to balance walking stability and smooth unloading; 3. Uneven stress on the mechanical structure leads to jamming, short lifespan, cumbersome operation, and is not in line with children's usage habits.

[0003] Based on the above shortcomings, it is necessary to provide a toy sanitation vehicle structure that is easy to operate, has strong linkage, stable attachment, and high simulation. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simulated toy sanitation vehicle. It achieves synchronous control of the vehicle body flipping and the cover opening and closing through an integrated linkage mechanism, and is equipped with a dual-mode hanging bucket unloading mechanism to balance walking stability and unloading smoothness, thereby improving the playability and simulation of the toy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A simulated toy sanitation vehicle includes a body assembly, a vehicle compartment linkage tilting mechanism, a dual-mode hook-and-loop unloading mechanism, and a garbage bin.

[0006] The vehicle body assembly includes a chassis frame, a cargo box body, and a tilting connector; the cargo box body is hinged to the rear of the chassis frame via the tilting connector, which has a sliding groove.

[0007] The carriage linkage tilting mechanism includes an operating component, a transmission component, a pushing component, and a cover plate assembly; the operating component is rotatably mounted on the chassis frame and is connected to the transmission component; the pushing component is reciprocating along the length of the chassis frame and is connected to the transmission component, and the pushing component is provided with a sliding part that can be slidably embedded in a sliding groove; the cover plate assembly is installed at the carriage body's loading port and is linked with the pushing component.

[0008] Rotating the operating component drives the pushing component to move linearly, simultaneously achieving the tilting of the truck body and the opening and closing of the cover assembly. The dual-mode hanging bin unloading mechanism is rotatably located at the rear of the truck body. The garbage bin has stepped hooking protrusions on both sides, including an upper hooking position and a lower hooking position. The hanging bin bracket is equipped with hanging bin fork arms that cooperate with the hooking protrusions. The hanging bin bracket can selectively engage with any hooking position, allowing the garbage bin to switch between walking mode and unloading mode.

[0009] Furthermore, the transmission assembly includes a turntable fixed coaxially with the operating member, and a transmission member with one end eccentrically hinged to the turntable and the other end hinged to the push member, forming a crank-slider transmission structure.

[0010] Furthermore, the flip-connector is provided with two parallel straight slide grooves, and the sliding part is a transverse slide shaft with both ends respectively embedded in the two slide grooves, so that the force is uniform and the movement is stable.

[0011] Furthermore, the carriage linkage tilting mechanism is also equipped with a carriage locking mechanism, which consists of a snap-fit ​​component and an elastic component. The carriage is automatically unlocked when the turntable rotates and automatically locked after resetting.

[0012] Furthermore, the cover plate assembly consists of a cover plate, a fastener, a pusher, and an elastic element. The pusher drives the fastener to move through the pusher, thereby achieving automatic unlocking and locking of the cover plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Integrated linkage control: A single operating component can simultaneously realize the entire process of unlocking the carriage, opening and closing the cover, tilting the carriage, and resetting and locking, resulting in smooth operation and high simulation. 2. Dual-mode hanging bucket is stable and reliable: the low-position hanging ensures that the bucket does not shake when moving, while the high-position hanging facilitates tipping and unloading, adapting to different usage scenarios; 3. Stable and durable structure: The combination of double slide grooves and horizontal slide shaft ensures even force distribution and prevents jamming, making it suitable for frequent use by children.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-10 As shown, this embodiment discloses a simulated toy sanitation vehicle, including a vehicle body assembly 1, a dual-mode hanging bucket unloading mechanism 2, a garbage bin 3, and a vehicle compartment linkage tilting mechanism 4.

[0018] I. Body Assembly 1 The vehicle body assembly 1 includes a chassis frame 11, a cab shell 12, a set of wheels for running on the road 13, a cargo box body 14, and a tilting connecting seat 15.

[0019] The bottom of the carriage body 14 is fixed with a flip-up connecting seat 15. The flip-up connecting seat 15 is hinged to the rear of the chassis frame 11 via a hinge shaft, and can be flipped upwards for unloading.

[0020] The flip-up connecting seat 15 has two parallel straight slide grooves 151 that extend along the length of the chassis frame.

[0021] II. Dual-mode hanging bucket unloading mechanism 2 and garbage bin 3 The dual-mode bucket unloading mechanism 2 is rotatably installed at the rear of the carriage body 14, including a bucket bracket 21 and a manually operated rocker arm 22.

[0022] The trash can 3 has stepped hooking protrusions 31 on both sides, forming an upper hooking position 311 and a lower hooking position 312, and correspondingly set a first buckle 32 and a second buckle 33. The end of the hooking fork arm 211 is provided with a beveled guide structure 213, which is used to guide the hooking fork arm 211 and the hooking positions (311, 312) to engage.

[0023] (a) Walking mode: The fork arm 211 of the hanging bin is engaged with the lower hook position 312, and the slot 212 is engaged with the second buckle 33 to form a double engagement. The garbage bin 3 is fixed in a low position and walks stably without shaking. The garbage bin 3 is raised and its bottom does not contact the ground, which can simulate the scene of a sanitation vehicle pulling a garbage bin.

[0024] (ii) Unloading mode: The bucket fork arm 211 is inserted into the upper hook position 311, the slot 212 is engaged with the first buckle 32, and the manual operation rocker arm 22 can be rotated to drive the garbage can to flip and unload.

[0025] Trash can 3 is securely locked to the hanging bracket 21, ready to be flipped. The top of trash can 3 has a rotatable flip-top. A child can manually operate the rocker arm 22 by pushing it downwards. The rocker arm 22 causes the hanging bracket 21 and the trash can 3 to flip upwards. When the trash can 3 tilts to a set angle, the flip-top automatically opens under gravity, allowing the contents of the trash can 3 (such as pebbles, building blocks, etc.) to be emptied into the vehicle body 14. During the flipping process, the trash can 3 will not fall off due to the double locking mechanism.

[0026] III. Carriage linkage tilting mechanism 4 The car body linkage tilting mechanism 4 is the core linkage system, including operating component 41, turntable 42, transmission component 43, pushing component 44, car body locking mechanism 45, and cover plate assembly 46.

[0027] (a) Transmission structure: The operating component 41 is rotatably mounted on the front of the chassis frame and is fixed coaxially with the turntable 42; one end of the transmission component 43 is eccentrically hinged to the turntable 42, and the other end is hinged to the non-end position of the push component 44, forming a crank-slider mechanism that converts rotation into linear movement.

[0028] The pusher (44) is reciprocating along the length of the chassis frame (11) and connected to the transmission assembly. The pusher (44) is provided with a sliding part (441), which can be slidably embedded in the slide groove (151). The cover plate assembly (46) is installed at the delivery port of the carriage body (14) and linked with the pusher (44). The pusher 44 can move linearly along the length of the chassis frame 11. Its end is fixedly connected with the sliding part 441 in the transverse direction. The diameter of the sliding shaft of the sliding part 441 is 3mm, and the width of the slide groove 151 is 3.2mm. The two are fitted with a clearance of 0.2mm. The two ends of the sliding part 441 are respectively inserted into two parallel slide grooves 151 on the flip connecting seat 15 to achieve a clearance sliding fit, ensuring smooth sliding without jamming.

[0029] (ii) Carriage locking mechanism 45: includes a swingable latching member 451 and an elastic member 453; the elastic member 453 is a compression spring; the latching member 451 is provided with a latch hook 452, and a through hole 111 is opened on the upper surface of the chassis frame (11) corresponding to the position of the latch hook 452. The latch hook 452 can pass through the through hole 111 and engage with the latching groove 141 of the carriage body 14 to achieve locking. The latching member 451 is rotatably installed inside the chassis frame 11 via a rotating shaft around the vertical axis, and its front end is integrally formed with a hook-shaped latch that cooperates with the carriage body 14. One end of the elastic member 453 is connected to the latching member 451, and the other end is connected to the chassis frame 11, applying a force to the latching member 451 to make its latch hook move upward. In the initial state, the elastic element 453 drives the latching element 451, causing the hook to pass through the through hole 111 and engage in the latching groove 141, locking the carriage body 14 onto the chassis frame 11. In this embodiment, the drive unit 421 on the turntable 42 is a lever structure. When the operating element 41 drives the turntable 42 to rotate, the drive unit 421 rotates accordingly and actuates the latching element 451, causing it to rotate against the force of the elastic element 453, thereby driving the hook to move downward and disengage from the latching groove 141, completing the unlocking of the carriage body 14.

[0030] (III) Cover plate assembly 46: includes cover plate 461, locking member 462, latching member 463, pushing member 464, and elastic element 465. The latching member 463 is a seesaw-type structure, which is rotatably mounted on the top of the flip-up connecting seat 15 via a rotating shaft around a horizontal axis; when the pushing member 44 moves backward, it pushes the pushing member 464, and drives the abutment surface on the latching member 463 to rotate through the inclined driving surface; in this embodiment, the elastic element 465 is a cylindrical helical spring, one end of which is connected to the flip-up connecting seat 15, and the other end is connected to the latching member 463, applying a force to the latching member 463 to make its front end tend to swing downward (i.e., the release position). The locking element 462 is a telescopic latch that can be movably mounted in the guide groove on the inner side wall of the cover plate 461. The locking element 462 is kept in a downward extended state by its own weight, without the need for elastic elements. When the cover plate 461 is closed, the locking element 462 abuts against the latch 463 and retracts upward under the pressure. After passing the latch 463, it automatically resets downward under its own weight and forms a locking engagement with the latch 463. When the latch 463 is rotated to release, the locking element 463 can naturally disengage as the cover plate opens. The structure is simple and the operation is reliable. It belongs to the conventional self-weight telescopic latch structure.

[0031] (iv) Linkage Workflow: ① Rotate the operating component → turntable drive unit unlocks the carriage; ② Transmission component pushes the pusher component backward → cover plate unlocks and opens; ③ Pusher component slides along the chute → pushes the carriage upward to overturn and unload; ④ Rotate the operating component in the opposite direction → carriage falls back → cover plate closes and locks → carriage automatically locks.

[0032] This invention achieves one-click unloading through pure mechanical linkage, and the dual-mode hanging bucket combines stability and convenience. It has a reliable structure, simple operation, and high simulation degree, making it suitable for children to use and for mass production.

[0033] The side walls of the carriage have several through holes of different shapes for observing the interior and placing items inside, making it easier for children to observe the interior of the carriage or put items into the carriage, thus increasing the fun of playing.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various adjustments and improvements can be made to the position, connection relationship, and material parameters of the components without departing from the principle of the present invention, and these should also be considered within the scope of protection of the present invention.
