Description

Technical Field

[0001] This utility model relates to the field of remote-controlled toy trucks, specifically a remote-controlled toy truck with a support structure. Background Technology

[0002] Remote-controlled toy trucks are popular toys among children, typically consisting of a cab and a cargo box. The cargo box and cab are usually connected by a plug-in joint for easy replacement of different cargo boxes or storage. However, most existing plug-in methods use simple pins or clips, which can easily loosen when the toy encounters bumpy roads, causing the cargo box to separate from the cab and affecting the play experience.

[0003] In addition, some remote-controlled toy trucks, to increase fun or for static display, have support structures, such as outriggers, at the bottom of the truck bed to lift the vehicle when parked. Existing support structures often borrow from industrial or adult models, such as electric actuators and lifting threaded rods. However, electric actuators typically require multiple precision components, including a motor, reduction gear set, lead screw, and nut, while lifting threaded rods rely on the rotation of a threaded pair to achieve linear motion. Both require numerous transmission links, resulting in a large number of parts and complex assembly. Furthermore, the motor drives the threaded rod to rotate multiple times to convert it into a small linear displacement of the outrigger, thus resulting in a slow lifting response. Utility Model Content

[0004] In order to overcome the above-mentioned defects such as complex structure, slow response speed, high cost and unstable connection between the front and body of the vehicle, this utility model provides a remote-controlled toy truck with a support structure.

[0005] To solve the above problems, this utility model is implemented according to the following technical solution:

[0006] The present invention discloses a remote-controlled toy truck with a support structure, including a truck head and a truck body. The truck head is provided with an interface, and the truck body is provided with a plug-in component. The plug-in component can be inserted into the interface to connect the truck head and the truck body.

[0007] The bottom of the carriage is provided with a support assembly, which is pulsatorically connected to the plug-in assembly and is used to control the opening and closing of the support assembly;

[0008] The support assembly includes a fixed shell, which is fixed to the bottom of the carriage. The bottom of the fixed shell is provided with a cylindrical shell and a limiting shell, and a support leg passes through the limiting shell.

[0009] The support assembly further includes a lifting assembly, which comprises a moving sleeve and a lifting sleeve. The moving sleeve and the lifting sleeve are formed by dividing the same mother sleeve through a curved cross-section and are arranged coaxially. The moving sleeve can rotate around the axis. The lifting sleeve is slidably fitted inside the cylindrical shell and is movably arranged along the axial direction, and forms a rotational coupling with the moving sleeve through a curved surface fitting structure. When the moving sleeve rotates, its curved cross-sectional profile pushes the mating curved surface of the lifting sleeve, driving the lifting sleeve to slide along the axial direction. The lifting sleeve is fixedly connected to the support leg.

[0010] Furthermore, a return spring is installed at the bottom of the lifting sleeve, and the other end of the return spring is connected to the bottom of the cylindrical shell.

[0011] Furthermore, a drive gear is fixedly connected to the top of the actuating sleeve, and a connecting shaft is rotatably connected to the top of the drive gear. The top of the connecting shaft extends to the top of the fixed housing, and a drive wheel is provided on the top of the connecting shaft. The interior of the carriage is provided with a drive assembly that is connected to the drive gear.

[0012] Furthermore, the drive assembly includes a servo motor, a worm gear is fixedly connected to the outer end of the drive shaft of the servo motor, a worm wheel meshes with the outer wall of the worm gear, and a transmission gear is fixedly connected to the bottom of the worm wheel, the transmission gear meshing with the drive gear.

[0013] Furthermore, a lubricating coating is provided between the inner wall of the actuating sleeve and the outer wall of the lifting sleeve, and the curved cross-section is divided into a helical surface; when the actuating sleeve rotates in the forward direction, the lifting sleeve retracts upward; when the actuating sleeve rotates in the reverse direction, the lifting sleeve extends downward.

[0014] Furthermore, the plug-in assembly includes a plug-in housing, which is fixedly installed at the bottom of the carriage. A rotating shaft extending into the carriage is rotatably connected inside the plug-in housing. A guide plate is installed at the bottom of the rotating shaft, and the guide plate has guide strip holes arranged in a circular array. A synchronous pulley is fixedly connected to the top of the rotating shaft. The synchronous pulley and the drive wheel are fitted with the same synchronous belt. A sliding rail arranged in a circular array is provided on the bottom surface of the inner cavity of the plug-in housing. An expansion block arranged in a circular array and extending to the outside of the plug-in housing is provided inside the plug-in housing. A push pin extending into the guide strip holes is provided at the top of the expansion block, and a sliding block extending into the sliding rail is provided at the bottom of the expansion block.

[0015] Furthermore, an anti-slip pad is fixedly connected to the bottom of the support leg, and the bottom surface of the anti-slip pad is provided with rubber protrusions.

[0016] Furthermore, the cross-section of the support leg is rectangular, and the inner cavity shape of the limiting shell is adapted to the cross-section of the support leg.

[0017] Furthermore, the drive gear and the actuating sleeve are integrally formed, and the pitch circle diameter of the drive gear is larger than the outer diameter of the actuating sleeve.

[0018] Furthermore, the number of guide strip holes is six, and the six guide strip holes are evenly distributed at 60° along the circumference of the guide disk. The number of expansion blocks is six, and the push pin of each expansion block is inserted into the guide strip hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention uses only one set of drive components to drive the drive gear, which in turn drives the rotating sleeve. The curved contour of the sleeve pushes the lifting sleeve to slide axially, thereby raising and lowering the outrigger. At the same time, the connecting shaft and drive wheel are linked to the plug-in assembly, which allows the plug-in assembly to expand or contract radially in sync with the movement of the support assembly. When the outrigger is raised and the carriage is connected to the front of the vehicle, the plug-in assembly expands and locks, making the connection more secure. When the outrigger is lowered and the carriage is separated from the front of the vehicle, the plug-in assembly contracts, facilitating separation.

[0021] The system achieves simultaneous support lifting, connection locking, and disengagement via a single power source, eliminating the need for separate power sources. The curved surface mating structure replaces complex push rods or threaded rods, resulting in fewer parts, faster response, and lower cost. Furthermore, since the plug-in assembly and support assembly share the same drive component, separate power sources for connection and support are unnecessary, significantly simplifying the overall structure, reducing manufacturing costs, and simplifying the control logic.

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] like Figures 1 to 4 As shown, this embodiment provides a remote-controlled toy truck with a support structure, including a truck head 1 and a truck body 2. The rear end face of the truck head 1 is provided with an insertion interface 11, and the front bottom of the truck body 2 is fixedly installed with a plug-in component 3. The plug-in component 3 can be inserted into the insertion interface 11 to connect the truck head 1 and the truck body 2.

[0040] like Figures 5 to 7As shown, a support assembly 4 is provided at the bottom of the carriage 2. The support assembly 4 is tractively connected to the plug-in assembly 3 and is used to control the opening and closing of the support assembly 4. Specifically, the support assembly 4 includes a fixed shell 41, which is fixed to the bottom of the carriage 2. A cylindrical shell 411 is integrally formed at the bottom of the fixed shell 41, and limit shells 412 are integrally formed on both sides of the bottom of the fixed shell 41. A support leg 42 passes through the limit shell 412.

[0041] The cylindrical shell 411 has a lifting assembly 43 for driving the outrigger 42 to rise and fall. The lifting assembly 43 includes an actuating sleeve 431 and a lifting sleeve 432. The actuating sleeve 431 and the lifting sleeve 432 are formed by dividing the same mother sleeve through a curved cross-section, and are arranged coaxially. The actuating sleeve 431 is rotatably mounted inside the fixed shell 41 about its axis. The lifting sleeve 432 is slidably fitted inside the cylindrical shell 411 and is axially movable, and forms a rotational coupling with the actuating sleeve 431 through a curved surface fit structure.

[0042] Specifically, such as Figure 5 As shown, the lower inner wall of the actuating sleeve 431 and the upper outer wall of the lifting sleeve 432 are respectively provided with mutually cooperating helical surfaces. When the actuating sleeve 431 rotates, its helical surface contour pushes the matching helical surface of the lifting sleeve 432, driving the lifting sleeve 432 to slide axially. The two side walls of the lifting sleeve 432 are fixedly connected to the support leg 42, thereby realizing the raising and lowering of the support leg 42.

[0043] A return spring 433 is installed at the bottom of the lifting sleeve 432. The other end of the return spring 433 is connected to the bottom of the cylindrical shell 411 to assist the lifting sleeve 432 in resetting.

[0044] A drive gear 434 is fixedly connected to the top of the actuating sleeve 431. Preferably, the drive gear 434 is integrally formed with the actuating sleeve 431, and the pitch circle diameter of the drive gear 434 is larger than the outer diameter of the actuating sleeve 431. A connecting shaft 435 is rotatably connected to the top of the drive gear 434. The top of the connecting shaft 435 extends above the fixed housing 41, and a drive wheel 436 is provided on the top of the connecting shaft 435. A drive assembly 44 that is driven by the drive gear 434 is provided inside the carriage 2.

[0045] like Figures 7 to 13As shown, the plug-in assembly 3 includes a plug-in housing 31, which is fixedly installed at the bottom of the carriage 2. A rotating shaft 32 extending into the carriage 2 is rotatably connected inside the plug-in housing 31. A guide plate 33 is mounted at the bottom of the rotating shaft 32, and the guide plate 33 has guide strip holes 331 arranged in a circular array. A synchronous pulley 332 is fixedly connected to the top of the rotating shaft 32, and the synchronous pulley 332 and the drive wheel 436 are fitted with the same synchronous belt 34. A sliding rail 35 arranged in a circular array is provided on the bottom surface of the inner cavity of the plug-in housing 31. An expansion block 36 arranged in a circular array and extending to the outside of the plug-in housing 31 is provided inside the plug-in housing 31. A push pin 361 extending into the guide strip holes 331 is provided at the top of the expansion block 36, and a sliding block 362 extending into the sliding rail 35 is provided at the bottom of the expansion block 36.

[0046] In this embodiment, there are six guide strip holes 331, and the six guide strip holes 331 are evenly distributed at 60° along the circumference of the guide disk 33. There are also six expansion blocks 36, and the push pin 361 of each expansion block 36 is inserted into the corresponding guide strip hole 331.

[0047] like Figure 4 As shown, the drive assembly 44 includes a servo motor 441, a worm gear 442 is fixedly connected to the outer end of the drive shaft of the servo motor 441, a worm wheel 443 is meshed on the outer wall of the worm gear 442, and a transmission gear 444 is fixedly connected to the bottom of the worm wheel 443. The transmission gear 444 meshes with the drive gear 434.

[0048] As a further preferred technical solution, a lubricating coating is provided between the inner wall of the actuating sleeve 431 and the outer wall of the lifting sleeve 432. When the actuating sleeve 431 rotates in the forward direction, the lifting sleeve 432 retracts upward; when the actuating sleeve 431 rotates in the reverse direction, the lifting sleeve 432 extends downward.

[0049] To prevent the lifting sleeve 432 from rotating along with the actuating sleeve 431, the inner wall of the cylindrical shell 411 is provided with an axial keyway, and the outer wall of the lifting sleeve 432 is provided with an anti-rotation protrusion key that slides with the axial keyway.

[0050] Furthermore, the support leg 42 has a rectangular cross-section, and the inner cavity shape of the limiting shell 412 is adapted to the cross-section of the support leg 42. An anti-slip pad is fixedly connected to the bottom of the support leg 42, and the bottom surface of the anti-slip pad has rubber protrusions.

[0051] The working principle of this utility model of a remote-controlled toy truck with a supporting structure is as follows:

[0052] When it is necessary to connect and lock the carriage 2 to the locomotive 1, the servo motor 441 rotates forward, driving the drive gear 434 to rotate forward via the worm gear 442, worm wheel 443, and transmission gear 444. The drive gear 434, on one hand, drives the actuating sleeve 431 to rotate forward, pushing the lifting sleeve 432 upward through the helical surface and compressing the return spring 433, thereby raising the outrigger 42; on the other hand, the drive gear 434 drives the synchronous pulley 332 to rotate via the connecting shaft 435, drive wheel 436, and synchronous belt 34, causing the guide plate 33 to rotate forward. The guide slot 331 drives the expansion block 36 to expand radially outward along the sliding rail 35 via the pushing pin 361, tightly abutting against the inner wall of the insertion interface 11, achieving insertion and locking. At this time, the outrigger 42 is in the raised state, and the carriage 2 and the locomotive 1 are firmly connected.

[0053] When it is necessary to separate the carriage 2 from the head carriage 1, the servo motor 441 rotates in the opposite direction, the push sleeve 431 rotates in the opposite direction, and the lifting sleeve 432 slides downward under the action of the return spring 433, driving the outrigger 42 to descend; at the same time, the guide plate 33 rotates in the opposite direction, the expansion block 36 retracts radially inward, releasing the locking of the plug-in interface 11, and the head carriage 1 and the carriage 2 can be easily separated.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
