Description

Rear wheel folding toy tricycle Technical Field

[0001] This utility model relates to a toy vehicle, and more specifically to a toy tricycle capable of making its rear wheels roll. Background Technology

[0002] Toy motorcycles are a common type of toy. To increase their appeal, many toys are designed as transformable toys with two states. A transformable toy motorcycle has at least one swingable transformation mechanism that allows it to switch between two states. Toy motorcycles require a drive mechanism to power the various moving parts. Existing drive mechanisms typically include a motor and a gear set. The motor outputs power through the gear set, driving the various moving parts to perform their actions.

[0003] For example, the applicant's earlier application, with publication number CN222585535U and title "A Deformable Toy Motorcycle That Can Effectively Prevent Damage to the Deformation Mechanism," includes a motorcycle shell and a drive unit installed inside the motorcycle shell. The deformable toy motorcycle is characterized by: at least one deformation mechanism installed on the motorcycle shell and connected to the drive unit, which drives the deformation mechanism to swing; the drive unit includes a reciprocating intermittent motion component; and the deformation mechanism includes a state-convertible unit, a passive swing frame, and a power conversion unit.

[0004] However, the applicant found that although the aforementioned transformable toy motorcycle has two states, its movements are relatively simple, which makes its visual impact insufficient. Since the users are usually young infants and toddlers, in order to stand out from other competing products, it is necessary to design a transformable toy motorcycle with more interesting movements and greater visual impact. Summary of the Invention

[0005] The purpose of this invention is to provide a toy tricycle with a reversible rear wheel, wherein the rear wheel unit of this toy tricycle can alternate between a driving state and a lying-flat rotating state. The technical solution adopted is as follows:

[0006] A toy three-wheeled motorcycle with a reversible rear wheel includes a shell, a body, a drive unit, a swivel wheel assembly, a rear wheel unit, and two front wheel units. The shell and drive unit are respectively mounted on the body. The two front wheel units are respectively mounted on the left and right sides of the front of the shell. The rear wheel unit is rotatably mounted on the rear of the body. The drive unit is connected to the rear wheel unit via a longitudinal transmission mechanism and drives the rear wheel unit to rotate. The swivel wheel assembly is mounted on the bottom surface of the body, and the drive unit is connected to the swivel wheel assembly and drives the swivel wheel assembly to rotate.

[0007] In a preferred embodiment, the rear wheel unit includes a rear wheel frame and at least one rear wheel. The front end of the rear wheel frame is rotatably mounted on the rear end of the vehicle body. At least one transverse axle extending laterally along the vehicle body is mounted on the rear wheel frame. The number of rear wheels and transverse axles are the same and correspond one-to-one. Each rear wheel is fixed on the corresponding transverse axle. The longitudinal transmission mechanism includes a first crown gear, a first gear, a second gear, a longitudinal transmission shaft, a second crown gear, and a third gear. The longitudinal transmission shaft is rotatably mounted on the vehicle body. The first crown gear and the first gear are fixed together and rotatably mounted on the vehicle body. A drive unit is connected to the first gear and drives the first gear to rotate. The second gear is mounted on the front end of the longitudinal transmission shaft and corresponds one-to-one with the first crown gear and can mesh with each other. The third gear is mounted on a transverse axle. The second crown gear is mounted on the rear end of the longitudinal transmission shaft and corresponds one-to-one with the third gear and can mesh with each other.

[0008] A better embodiment is that the vehicle body has a limiting groove, the front side of the rear wheel frame has a longitudinal positioning sleeve, the longitudinal drive shaft is installed in the longitudinal positioning sleeve, the outer wall of the longitudinal positioning sleeve has a fan-shaped controlled limiting step, and the controlled limiting step is rotatably set in the limiting groove.

[0009] A better solution involves installing a control mechanism on the vehicle body. This mechanism drives the longitudinal positioning sleeve to rotate alternately in both directions. A lifting rod is located on one side of the limiting groove. When the longitudinal positioning sleeve rotates, and the fan-shaped controlled limiting step abuts against the lifting rod, the front of the longitudinal positioning sleeve rises, disengaging the second gear of the longitudinal transmission mechanism from the first crown gear. When the longitudinal positioning sleeve rotates in the opposite direction, and the fan-shaped controlled limiting step moves away from the lifting rod, the front of the longitudinal positioning sleeve descends back into the limiting groove, re-engaging the second gear of the longitudinal transmission mechanism with the first crown gear, thus transmitting the power of the drive unit to the rear wheels.

[0010] A better solution is that the fan-shaped controlled limiting step is provided with a controlled rod, and the control mechanism includes an active turntable, a fourth gear, a swing plate, and a toggle component. The active turntable and the fourth gear are fixed together and rotatably mounted on the vehicle body. The drive unit is connected to the fourth gear and drives the fourth gear to rotate. The front end of the swing plate is rotatably mounted on the vehicle body, and a control groove is opened in the middle of the swing plate. The active turntable is horizontally set, and a control rod is located off-center on the top surface of the active turntable. The control rod is set in the control groove and drives the swing plate to swing back and forth. A toggle component is installed on the rear side of the swing plate. The toggle component clamps the controlled rod and drives the controlled rod to move back and forth along the transverse direction of the vehicle body, so that the longitudinal positioning sleeve continuously rotates alternately in the forward and reverse directions.

[0011] A better embodiment includes a mounting post on the rear side of the swing plate, and a toggle component comprising two toggle clamps, each mounted on the mounting post. The two toggle clamps extend downwards and towards the rear of the swing plate, clamping the controlled rod from both sides. When the swing plate swings, the two toggle clamps, holding the controlled rod, reciprocate laterally along the vehicle body, causing the longitudinal positioning sleeve to continuously and alternately rotate in the forward and reverse directions.

[0012] In a better embodiment, the lifting rod is located on the front side of the limiting groove. When the control rod rotates and abuts against the groove wall on the front side of the control groove, causing the swing plate to swing forward, the actuating element clamps the controlled rod and moves towards the lateral front side of the vehicle body, causing the longitudinal positioning sleeve to rotate until the fan-shaped controlled limiting step abuts against the lifting rod, at which point the front side of the longitudinal positioning sleeve will rise to its highest point. When the control rod rotates and abuts against the groove wall on the rear side of the control groove, causing the swing plate to swing backward, the actuating element clamps the controlled rod and moves towards the lateral rear side of the vehicle body, causing the longitudinal positioning sleeve to rotate until the fan-shaped controlled limiting step leaves the lifting rod, at which point the front side of the longitudinal positioning sleeve will descend back into the limiting groove.

[0013] A preferred embodiment is that when the second gear is disengaged from the first crown gear, the rear wheel is perpendicular to the vehicle body; when the second gear is engaged with the first crown gear, the rear wheel is parallel to the vehicle body.

[0014] The beneficial effect of this utility model compared with the prior art is that, since the rear wheel unit can alternate between driving state and lying-flat rotation state, it can produce a good visual effect. The control mechanism can control the drive unit to continuously rotate the rear wheel of the rear wheel unit through the longitudinal transmission mechanism in the lying-flat rotation state, while in the driving state, the connection between the drive unit and the longitudinal transmission mechanism is disconnected, so that the rear wheel loses power.

The direction "forward" refers to the left side of the vehicle body along the longitudinal direction. The direction "rearward" refers to the right side of the vehicle body along the longitudinal direction.

[0025] As shown in Figures 1-9, a rear-wheeled reversible tricycle in one embodiment of this application includes a shell 1, a body 2, a drive unit 3, a universal wheel device 4, a rear wheel unit 5, and two front wheel units 6. The shell 1 and the drive unit 3 are respectively mounted on the body 2. The two front wheel units 6 are respectively mounted on the left and right sides of the front of the shell 1. The rear wheel unit 5 is rotatably mounted on the rear end of the body 2. The drive unit 3 is connected to the rear wheel unit 5 through a longitudinal transmission mechanism 7 and drives the rear wheel unit 5 to rotate. The universal wheel device 4 is mounted on the bottom surface of the body 2. The drive unit 3 is connected to the universal wheel device 4 and drives the universal wheel device 4 to rotate.

[0026] As shown in Figures 1-9, in one optional embodiment of this application, the rear wheel unit 5 includes a rear wheel frame 501 and at least one rear wheel 502. The front end of the rear wheel frame 501 is rotatably mounted on the rear end of the vehicle body 2. At least one transverse pivot 5011 extending laterally along the vehicle body 2 is mounted on the rear wheel frame 501. The number of rear wheels 502 and transverse pivots 5011 are the same and correspond one-to-one. Each rear wheel 502 is fixed on the corresponding transverse pivot 5011. The longitudinal transmission mechanism 7 includes a first crown gear 701, a first gear 702, a second gear 703, a longitudinal transmission shaft 704, a second crown gear 705, and a third gear 706. 06. A longitudinal drive shaft 704 is rotatably mounted on the vehicle body 2. First crown gears 701 and 702 are fixed together and rotatably mounted on the vehicle body 2. A drive unit 3 connects to the first gear 702 and drives it to rotate. A second gear 703 is mounted at the front end of the longitudinal drive shaft 704 and corresponds one-to-one with the first crown gear 701, allowing them to mesh. A third gear 706 is mounted on a transverse rotating shaft 5011. A second crown gear 705 is mounted at the rear end of the longitudinal drive shaft 704 and corresponds one-to-one with the third gear 706, allowing them to mesh. In this embodiment, there are two rear wheels 502 and two transverse rotating shafts 5011.

[0027] As shown in Figures 6-8, in one optional embodiment of this application, the vehicle body 2 has a limiting groove 201, the front side of the rear wheel frame 501 has a longitudinal positioning sleeve 5011, the longitudinal drive shaft 704 is installed in the longitudinal positioning sleeve 5011, and the outer wall of the longitudinal positioning sleeve 5011 has a fan-shaped controlled limiting step 5012, which is rotatably disposed in the limiting groove 201.

[0028] As shown in Figures 6-8, in one optional embodiment of this application, the rear wheel frame 501 is composed of a first rear wheel frame assembly 5015 and a second rear wheel frame assembly 5014.

[0029] As shown in Figures 4-6, in one optional embodiment of this application, a control mechanism 8 is also installed on the vehicle body 2. The control mechanism 8 drives the longitudinal positioning sleeve 5011 to rotate alternately in the forward and reverse directions. A lifting rod 202 is provided on one side of the limiting groove 201. When the longitudinal positioning sleeve 5011 rotates, and the fan-shaped controlled limiting step 5012 abuts against the lifting rod 202, the front side of the longitudinal positioning sleeve 5011 will rise upward, causing the second gear 703 of the longitudinal transmission mechanism 7 to disengage from the first crown gear 701. When the longitudinal positioning sleeve 5011 rotates in the reverse direction, and the fan-shaped controlled limiting step 5012 moves away from the lifting rod 202, the front side of the longitudinal positioning sleeve 5011 will descend back into the limiting groove 201, causing the second gear 703 of the longitudinal transmission mechanism 7 to re-engage with the first crown gear 701, thus enabling the power of the drive unit 3 to be transmitted to the rear wheel 502.

[0030] As shown in Figures 4-6, in one optional embodiment of this application, a controlled rod 5013 is provided on the fan-shaped controlled limiting step 5012. The control mechanism 8 includes an active turntable 801, a fourth gear 802, a swing plate 803, and a toggle 804. The active turntable 801 and the fourth gear 802 are fixed together and rotatably mounted on the vehicle body 2. The drive unit 3 is connected to the fourth gear 802 and drives the fourth gear 802 to rotate. The front end of the swing plate 803 is rotatably mounted on the vehicle body 2. 3. A control slot 8031 ​​is provided in the middle. The active turntable 801 is horizontally set and a control rod 8011 is located off-center on the top surface of the active turntable 801. The control rod 8011 is set in the control slot 8031 ​​and drives the swing plate 803 to swing back and forth. A toggle 804 is installed on the rear side of the swing plate 803. The toggle 804 clamps the controlled rod 5013 and drives the controlled rod 5013 to move back and forth along the transverse direction of the vehicle body 2, so that the longitudinal positioning sleeve 5011 continuously rotates alternately in the forward and reverse directions.

[0031] As shown in Figures 4-6, in one optional embodiment of this application, the swing plate 803 has a mounting post 8032 on its rear side, and the actuating member 804 includes two actuating clamps 8041. The two actuating clamps 8041 are respectively mounted on the mounting post 8032. The two actuating clamps 8041 extend downward toward the rear side of the swing plate 803 and clamp the controlled rod 5013 from both sides. When the swing plate 803 swings, the two actuating clamps 8041 clamp the controlled rod 5013 and move back and forth along the lateral side of the vehicle body 2, thereby causing the longitudinal positioning sleeve 5011 to continuously rotate alternately in the forward and reverse directions.

[0032] As shown in Figures 4-8, in one optional embodiment of this application, the lifting rod 202 is located in front of the limiting groove 201. When the control rod 8011 rotates and abuts against the groove wall in front of the control groove 8031, causing the swing plate 803 to swing forward, the actuating member 804 clamps the controlled rod 5013 and moves it towards the lateral front of the vehicle body 2, causing the longitudinal positioning sleeve 5011 to rotate until the fan-shaped controlled limiting step 5012 abuts against the lifting rod 202, and the longitudinal positioning sleeve 5011 rotates. The front side of 011 will rise to the highest point; when the control lever 8011 rotates and abuts against the groove wall of the control groove 8031 ​​and drives the swing plate 803 to swing backward, the toggle member 804 clamps the controlled lever 5013 and moves towards the rear side of the vehicle body 2, causing the longitudinal positioning sleeve 5011 to rotate until the fan-shaped controlled limiting step 5012 leaves the lifting lever 202, and the front side of the longitudinal positioning sleeve 5011 will fall back into the limiting groove 201.

[0033] As shown in Figures 4-8, in one optional embodiment of this application, when the second gear 703 is disengaged from the first crown gear 701, the rear wheel 502 is perpendicular to the vehicle body 2; when the second gear 703 is engaged with the first crown gear 701, the rear wheel 502 is parallel to the vehicle body 2.

[0034] As shown in Figures 1, 3, and 4, in one alternative embodiment of this application, the vehicle body 1 covers the drive unit 3.

[0035] As shown in Figure 4, in one optional embodiment of this application, the vehicle body 2 is composed of a first vehicle body component 203 and a second vehicle body component 204.

[0036] As shown in Figures 1-3, in one optional embodiment of this application, the front wheel unit 6 includes a front wheel frame 601 and a front wheel 602. The front wheel frame 601 is mounted on the vehicle body 1, and the front wheel 602 is mounted on the front wheel frame 601.

[0037] As shown in Figures 5-7, in one optional embodiment of this application, the drive unit 3 includes a motor 301 and a gear set 302. The motor 301 and gear set 302 are respectively mounted on the vehicle body 2, and one gear of the gear set 302 is mounted on the output shaft of the motor 301. The power output by the motor 301 is transmitted to the universal wheel device 4, the longitudinal transmission mechanism 7, and the control mechanism 8 through the gear set 302.

[0038] The working process of the toy reverse tricycle is explained below with reference to Figure 1-9:

[0039] When the motor 301 is working, it drives the universal wheel device 4 to rotate through the gear set 302, which in turn drives the longitudinal transmission mechanism 7 and the control mechanism 8.

[0040] The active turntable 801 of the control mechanism 8 rotates, causing the control lever 8011 to move along an arc. Since the control lever 8011 is located in the control slot 8031, the control lever 8011 drives the swing plate 803 to swing back and forth.

[0041] When the swing plate 803 swings, the two actuating clamps 8041 clamp the controlled rod 5013 and move back and forth along the lateral side of the vehicle body 2, thereby causing the longitudinal positioning sleeve 5011 to continuously rotate alternately in the forward and reverse directions:

[0042] When the longitudinal positioning sleeve 5011 rotates, and the fan-shaped controlled limiting step 5012 abuts against the lifting rod 202, the front side of the longitudinal positioning sleeve 5011 will rise upward, causing the second gear 703 of the longitudinal transmission mechanism 7 to disengage from the first crown gear 701. When the longitudinal positioning sleeve 5011 rotates in the opposite direction, and the fan-shaped controlled limiting step 5012 moves away from the lifting rod 202, the front side of the longitudinal positioning sleeve 5011 will descend back into the limiting groove 201, causing the second gear 703 of the longitudinal transmission mechanism 7 to re-engage with the first crown gear 701, thus enabling the power of the drive unit 3 to be transmitted to the rear wheel 502.

[0043] When the second gear 703 disengages from the first crown gear 701, the rear wheel 502 is perpendicular to the vehicle body 2. Due to the rotation of the universal wheel device 4, the toy tricycle moves on a flat surface (such as the ground or a tabletop), and the rear wheel unit 5 is in a driving state. The rear wheel unit 5 and the two front wheel units 6 are rolling on the flat surface. When the second gear 703 is engaged with the first crown gear 701, the rear wheel 502 is parallel to the vehicle body 2. At this time, the power of the drive unit 3 is transmitted to the rear wheel 502, causing the rear wheel 502 to rotate. The rear wheel unit 5 is in a lying-flat rotating state. This rear wheel can both flip and roll, and is simply referred to as a rollable wheel.

[0044] In several alternative embodiments, a light-emitting device and / or a sound-emitting device are provided on the rear wheel 502, so that when the rear wheel unit 5 is in a lying-flat rotating state, the rear wheel 502 can emit light and / or sound when it rotates, producing better visual effects and / or sound effects.

[0045] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, they should all fall within the protection scope of this utility model.
