Description

Technical Field

[0001] This utility model relates to the field of toys, and more particularly to a moving part and a toy. Background Technology

[0002] With the improvement of people's living standards, toys have become widely present in our lives, especially those closely related to children's lives. Currently, there are numerous types of toys on the market, including toy cars and toy airplanes. To further enhance children's knowledge and understanding, the styles of toys are also increasing. For example, in various dinosaur toys, the conventional design features a single, integrated foot structure, as seen in patent application number "201820631131.3" and patent title "A Dinosaur Toy." The top of the foot is directly connected to the body for rotation, and a cam structure drives the foot's reciprocating movement to achieve the dinosaur's movement. In this structure, the foot's motion mechanism mainly uses an eccentric wheel as its core, and the foot's movement is driven by the eccentric wheel. However, this structure has the following shortcomings:

[0003] It is primarily designed for slow walking and running movements. It cannot achieve the leaping motion characteristic of a velociraptor, or rather, the foot movements are poorly executed, lacking realism and dynamic accuracy, resulting in low playability and interactivity. Furthermore, the thigh, calf, and foot form a single unit, making coordinated movement of these parts impossible. Therefore, addressing these technical challenges is a direction that those skilled in the art need to explore. Summary of the Invention

[0004] The purpose of this invention is to provide a moving part and a toy, which improves the playability and aesthetics of the toy by using this structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a moving component, the top of which is rotatably mounted on a mounting component, a crankshaft being rotatably mounted on the mounting component, and the crankshaft being rotatably connected to the moving component;

[0006] The moving parts include a foot, a foot connecting rod, a lower leg connecting rod, a thigh connecting rod, and a crankshaft connecting rod. The upper part of the thigh connecting rod is rotatably connected to the mounting component. The two ends of the foot connecting rod are rotatably connected to the rear end of the foot and the bottom of the crankshaft connecting rod, respectively. The two ends of the lower leg connecting rod are rotatably connected to the bottom of the thigh connecting rod and the middle part of the foot connecting rod, respectively.

[0007] The middle part of the crankshaft connecting rod is rotatably connected to the middle part of the thigh connecting rod, the top of the crankshaft connecting rod is rotatably connected to the crankshaft, and the connection between the crankshaft connecting rod and the crankshaft is located on the side of the connection between the crankshaft and the mounting component.

[0008] In the above technical solution, a tension spring is also provided, the bottom of which is connected to the rear end of the foot, and the top of which is connected to the bottom of the lower leg connecting rod, or the top of which is connected to the connection between the lower leg connecting rod and the foot connecting rod.

[0009] In the above technical solution, the bottom of the foot is provided with an anti-slip layer.

[0010] This utility model also provides a toy, including the aforementioned moving parts.

[0011] In the above technical solution, a moving component is installed on each of the two sides of the mounting component, and the two moving components are respectively connected to a crankshaft; a power gear is provided inside the mounting component, and the two crankshafts are respectively connected to the two ends of the power gear;

[0012] The mounting component also includes a power unit, which is configured to drive the power gear to rotate. When the power gear rotates, it simultaneously drives the two sets of moving parts to rotate around the mounting component.

[0013] In the above technical solution, the power component is a spring device or a motor assembly. The spring device, motor assembly, or mounting component is provided with a drive gear. The spring device or motor assembly drives the drive gear to rotate, and the drive gear meshes with the power gear.

[0014] In the above technical solution, a first transmission gear and a second transmission gear are rotatably mounted on the mounting component. The two sides of the first transmission gear mesh with the second transmission gear and the driving gear, respectively, and the other side of the second transmission gear meshes with the power gear.

[0015] In the above technical solution, the mounting component is further provided with a limiting component. The outer end of the limiting component is located outside the mounting component. When the limiting component rotates to the first position, the inner end of the limiting component is inserted between two adjacent teeth of the power gear and restricts the rotation of the power gear. When the limiting component rotates to the second position, the inner end of the limiting component disengages from the two adjacent teeth of the power gear, and the limiting component releases the restriction on the rotation of the power gear.

[0016] In the above technical solution, the mounting component is also provided with two front claws;

[0017] And / or, a balance wheel is rotatably mounted on each of the front claws, the bottom outer surface of the balance wheel being disposed below the bottom of the front claw.

[0018] The above technical solution also includes a counterweight, which is disposed between the two front claws;

[0019] And / or, the two ends of the counterweight are respectively connected to the two front claws;

[0020] And / or, each of the front claws is respectively disposed on the front side of a moving part.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] 1. In this utility model, the moving parts adopt a foot, foot connecting rod, lower leg connecting rod, thigh connecting rod, and crankshaft connecting rod that are rotatably connected. The thigh connecting rod is rotatably connected to the mounting part, and the crankshaft connecting rod is used to connect the crankshaft, thigh connecting rod, and foot connecting rod. When the crankshaft rotates around the mounting part, the thigh connecting rod, lower leg connecting rod, foot connecting rod, and foot can be driven by the crankshaft connecting rod to achieve the movement of the moving parts. Thus, the two moving parts drive the entire mounting part to lift and move, making the toy more in line with the movement posture, more beautiful, more playable, and more interactive.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0044] Example 1: See Figure 1-11As shown, a moving component 1 is rotatably mounted on a mounting component 2 at its top. A crankshaft 21 is rotatably mounted on the mounting component 2, and the crankshaft 21 is rotatably connected to the moving component 1.

[0045] The moving part 1 includes a foot 11, a foot connecting rod 12, a calf connecting rod 13, a thigh connecting rod 14, and a crankshaft connecting rod 15. The upper part of the thigh connecting rod 14 is rotatably connected to the mounting part 2. The two ends of the foot connecting rod 12 are rotatably connected to the rear end of the foot 11 and the bottom of the crankshaft connecting rod 15, respectively. The two ends of the calf connecting rod 13 are rotatably connected to the bottom of the thigh connecting rod 14 and the middle part of the foot connecting rod 12, respectively.

[0046] The middle part of the crankshaft connecting rod 15 is rotatably connected to the middle part of the thigh connecting rod 14, the top of the crankshaft connecting rod 15 is rotatably connected to the crankshaft 21, and the connection between the crankshaft connecting rod 15 and the crankshaft 21 is located on the side of the connection between the crankshaft 21 and the mounting part 2.

[0047] In this utility model, the crankshaft includes a connecting plate 210, an inner shaft and an outer shaft 211 mounted on the connecting plate. The inner shaft and the outer shaft are respectively disposed at both ends of the connecting plate, with the inner shaft disposed on the inner side wall of the connecting plate and the outer shaft disposed on the outer side wall of the connecting plate. The connecting plate is rotatably connected to the mounting component via the inner shaft. The top of the crank connecting rod is rotatably connected to the outer shaft. The rotatable connection point between the thigh connecting rod and the mounting component (which is rotatably connected to the thigh connecting rod and the mounting component via the first connecting shaft 16) is disposed in front of, above, or beside the rotatable connection point between the inner shaft and the mounting component. In the illustrated direction, it is disposed in front of and above the inner shaft. The crankshaft connecting rod has an L-shaped or V-shaped structure. Preferably, in this embodiment, the crankshaft connecting rod has a V-shaped structure, which includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the outer shaft, and the other end of the first connecting rod is connected to the top of the second connecting rod. The bottom of the second connecting rod is rotatably connected to the top of the foot connecting rod (the crankshaft connecting rod and the foot connecting rod are connected here through a fourth connecting shaft 19). The connection between the first and second connecting rods is rotatably connected to the middle of the thigh connecting rod (the crankshaft connecting rod and the thigh connecting rod are connected through a second connecting shaft 17). The lower leg connecting rod is located beside the second connecting rod, and the connection between the lower leg connecting rod and the thigh connecting rod (the lower leg connecting rod and the thigh connecting rod are connected through a third connecting shaft 18) is located below the connection between the crankshaft connecting rod and the thigh connecting rod, and the connection between the lower leg connecting rod and the thigh connecting rod is located close to the connection between the crankshaft connecting rod and the thigh connecting rod. The connection between the lower leg link and the foot link is located below the connection between the second link and the foot link (the lower leg link and the foot link are connected by the fifth link 101), and the connection between the lower leg link and the foot link is located close to the connection between the second link and the foot link.

[0048] During its movement, the crankshaft rotates around the mounting component. Taking clockwise rotation as an example, in the initial state, as shown in the diagram, the connecting plate is horizontally positioned, the outer shaft is to the left of the inner shaft, and the sole of the foot is against the ground (taking the movement of the foot on the ground as an example). See [reference needed]. Figure 3 As shown in a. See also Figure 3 As shown, the steps are as follows:

[0049] S1. With the crankshaft rotated 90 degrees clockwise, the outer shaft rotates to the upper side of the inner shaft, the second connecting shaft rotates downwards, and the fourth connecting shaft rotates upwards. This will drive the thigh connecting rod to rotate clockwise, the calf connecting rod to rotate clockwise, and pull the foot connecting rod upwards, causing the foot to lift off the ground. (See below) Figure 3 As shown in b;

[0050] S2. The crankshaft continues to rotate 90 degrees clockwise, the outer shaft rotates to the right side of the inner shaft, driving the thigh connecting rod, the push-down connecting rod, and the foot connecting rod. The foot rotates counterclockwise, the first connecting rod presses down, causing the foot to lift and move forward. See the section below. Figure 3 As shown in c;

[0051] S3. The crankshaft continues to rotate 90 degrees clockwise, the outer shaft rotates to the lower left of the inner shaft, causing the thigh connecting rod, foot connecting rod, and foot to rotate clockwise, while the lower leg connecting rod rotates counterclockwise. At this point, the foot lands on the ground. (See below) Figure 3 As shown in d;

[0052] S4. The crankshaft continues to rotate 90 degrees clockwise. At this time, the bottom of the foot connecting rod rotates clockwise around the foot, and the bottom of the lower leg connecting rod rotates clockwise around the foot connecting rod. Since the bottom of the foot is supported on the ground, the first connecting shaft moves forward and upward (the first connecting shaft serves as the connection anchor point between the moving part and the mounting part), thus realizing the upward and forward movement of the mounting part.

[0053] See Figure 1-3 As shown, a tension spring 102 is also provided. The bottom of the tension spring 102 is connected to the rear end of the foot 11, and the top of the tension spring 102 is connected to the bottom of the lower leg connecting rod 13, or the top of the tension spring 102 is connected to the connection between the lower leg connecting rod 13 and the foot connecting rod 12.

[0054] The connection between the tension spring and the foot will be located on the rear side of the connection between the foot link and the foot. The tension spring will always provide an upward pulling force to the rear end of the foot. Therefore, during the process of step S2 to S3, when the bottom of the foot contacts the ground, the front end of the foot will contact the ground first, which is equivalent to the toes landing first. This is more in line with the posture of biological movement, which is not only more stable, but also more beautiful, and has a stronger aesthetic appeal and playability.

[0055] See Figure 1 , 2As shown, the bottom of the foot 11 is provided with an anti-slip layer 103. In this embodiment, the anti-slip layer is a silicone anti-slip layer. This ensures that when the bottom of the foot contacts the ground and the moving parts move, there will be no relative slippage between the foot and the ground, thereby stably pushing the mounting part upward and forward.

[0056] See Figure 4-11 As shown, this utility model also provides a toy, including the aforementioned moving parts 1. One of the moving parts 1 is mounted on each side of the mounting member 2, and the two moving parts 1 are respectively connected to a crankshaft 21; a power gear 22 is provided inside the mounting member 2, and the two crankshafts 21 are respectively connected to both ends of the power gear 22; in this embodiment, the two ends of the power gear rotatably connected to the mounting member respectively constitute the inner shafts of the two crankshafts.

[0057] The mounting component 2 is also provided with a power component 3, which is configured to drive the power gear 22 to rotate. When the power gear 22 rotates, it simultaneously drives the two sets of moving components 1 to rotate around the mounting component 2.

[0058] In this embodiment, the toy is a velociraptor toy, but it can also be other types of toys, especially toys with at least two hind legs (the moving parts serve as the hind leg structures). Taking an example where the two moving parts are respectively located on the left and right sides of the mounting, the outer shafts of the right and left crankshafts are symmetrically positioned on either side of the drive gear axis. For example, when the outer shaft of the right crankshaft is behind the drive gear axis, the outer shaft of the left crankshaft is in front of the drive gear axis; when the outer shaft of the right crankshaft is above the drive gear axis, the outer shaft of the left crankshaft is below the drive gear axis. In this configuration, the outer shaft of the crankshaft at the right moving part is to the left of the inner shaft, and the sole of the foot rests on the ground. The state of the right moving part at this time is described in the following example. Figure 3 As shown in step a, the state of the moving part on the left at this time is as described in step S2. Figure 3 As shown in c. In this method, when the foot of one moving part is ready to lift, the foot of the other moving part has already lifted, ready to land and push the mounted part (body) to lift and move forward. The two moving parts cycle through the motion, thus realizing the biomimetic movement of the velociraptor running forward. It is aesthetically pleasing and more playable.

[0059] The power component 3 is a spring device or a motor assembly. The spring device, motor assembly or mounting component is provided with a drive gear 31. The spring device or motor assembly drives the drive gear 31 to rotate. The drive gear 31 meshes with the power gear 31.

[0060] In this embodiment, the power component employs a spring-loaded mechanism, which is a structure found in the prior art. See also... Figure 6 , 7 As shown, the mainspring mechanism includes: a mainspring shaft 32 rotatably mounted on a mounting member 2, a ratchet 33 mounted on the mainspring shaft 32, and a mainspring 34 (coil spring) mounted outside the ratchet 33. A drive gear is rotatably mounted on the mounting member, and the drive gear has a ratchet groove inside. The ratchet is rotatably disposed in the ratchet groove. The inner end of the mainspring is connected to the outer surface of the mainspring shaft, and the outer end of the mainspring is connected to the mounting member. When the mainspring shaft is rotated and the ratchet is driven to rotate in the first direction, the ratchet can rotate in the ratchet groove (the ratchet will not drive the drive gear to rotate, and can rotate smoothly in the ratchet groove), thereby tightening the mainspring. When the mainspring shaft is loosened, the ratchet will abut against the ratchet groove, and the ratchet will lock the ratchet groove. The mainspring will drive the mainspring shaft, ratchet, and drive gear to rotate in the second direction. The first direction and the second direction are opposite. When the first direction is clockwise, the second direction is counterclockwise, and when the first direction is counterclockwise, the second direction is clockwise. When the drive gear rotates in the second direction, the meshing of the drive gear and the power gear simultaneously drives the power gear to rotate. This rotation of the power gear, in turn, drives the crankshafts on both sides of the mounting component to rotate, thus moving the moving parts on both sides and causing the Velociraptor toy to move forward. A hole is provided on the mounting component facing the spring shaft. A spring key 35 is inserted into the hole and connected to the spring shaft to wind the spring (the spring key is a detachable structure). Alternatively, the spring shaft can extend out of the mounting component, and a gripper (the gripper constitutes the spring key and is a non-detachable structure) can be provided on the outside of the mounting component to drive the spring shaft to rotate. Of course, the spring mechanism can also be other structures found in the prior art. This embodiment uses one such structure as an example. If the power component is a motor assembly, a battery compartment and a control switch are provided on the mounting component. The motor assembly uses a motor, or a combination of a motor and a reducer. A battery is installed in the battery compartment, and an idle switch controls the operation of the motor assembly. The motor assembly is powered by a battery, and the idle switch controls the operation of the motor assembly, thereby driving the rotation of the drive gear, which in turn drives two sets of moving parts through the power gear and crankshaft.

[0061] See Figure 6 , 7 As shown, a first transmission gear 23 and a second transmission gear 24 are rotatably mounted on the mounting component 2. The two sides of the first transmission gear 23 mesh with the second transmission gear 24 and the drive gear 31, respectively, and the other side of the second transmission gear 24 meshes with the power gear 22.

[0062] In this embodiment, if the distance between the power component and the power gear is relatively large, and in order to adjust the transmission ratio, a first transmission gear and a second transmission gear are also provided between the power gear and the drive gear for intermediate transmission. This ensures that when the drive gear rotates, it can drive the power gear to rotate, and at the same time, the transmission ratio can be adjusted. Of course, only one transmission gear can be used, or a larger number of transmission gears can be used, depending on the actual situation.

[0063] See Figure 4-7 As shown, the mounting component 2 is also rotatably provided with a limiting component 25. The outer end of the limiting component 25 is disposed outside the mounting component 2. When the limiting component 25 rotates to the first position, the inner end of the limiting component 25 is inserted between two adjacent teeth of the power gear 22 and restricts the rotation of the power gear 22. When the limiting component 25 rotates to the second position, the inner end of the limiting component 25 disengages from the two adjacent teeth of the power gear 22, and the limiting component 25 releases the restriction on the rotation of the power gear 22.

[0064] In this embodiment, to prevent the mainspring from rotating in the second direction after the mainspring shaft is released after the mainspring device is wound (for example, the winding process is when the mainspring is rotated in the first direction, and after the mainspring is wound, the mainspring shaft is released), the mainspring will drive the drive gear to rotate in the second direction, causing the moving parts to move on their own and making it impossible to control when the moving parts work (for example, if the user holds the toy in his hand and winds it up, and after winding is completed, but before the toy is placed on the ground or on the table where the toy wants to move, if the gripping force of the mainspring shaft or the mainspring key is released at this time, the restoring force of the mainspring will drive the drive gear to move). Therefore, a separate limiting component is also provided. Before winding and / or after winding, when the moving parts do not need to move temporarily, the limiting component is rotated to the first position, so that the inner end of the limiting component is inserted between two adjacent teeth of the drive gear. Thus, during the winding process, even if the rotational force of the mainspring shaft is released, when the restoring force of the mainspring pushes the ratchet and the drive gear to rotate in the second direction, the drive gear cannot rotate because it is limited by the limiting component. At this time, the drive gear also cannot rotate, thus achieving braking of the drive gear. When the user places the toy on the ground (taking the toy moving on the ground as an example), when the toy is ready to move, the user grasps the limiting component, causing the limiting component to rotate in the opposite direction to the second position, and disengaging the limiting component from the drive gear, releasing the rotation limit on the drive gear. At this time, the mainspring mechanism can drive the drive gear and the drive gear to rotate, thereby driving the moving parts to work and realizing the biomimetic movement of the Velociraptor toy.

[0065] Of course, the limiting component can also be inserted between two adjacent teeth of the drive gear, the first transmission gear, or the second transmission gear, thereby limiting the rotation of the power gear.

[0066] See Figure 8 , 9 As shown, the limiting component 25 includes a switch lever 250, a switch shaft 251, and a brake latch 252. The brake shaft is rotatably mounted on a mounting piece above or beside the power gear. The bottom of the switch lever is connected to the switch shaft, and the top of the switch lever protrudes above the top surface of the mounting piece. The rear side of the brake latch is connected to the switch shaft, and the bottom right side of the brake latch faces the power gear. Taking the illustrated direction as an example, when the user grasps the switch lever and rotates the switch shaft clockwise, the brake latch moves downward, rotating to the first position and engaging between two adjacent teeth of the power gear, thus restricting the rotation of the power gear. When the user grasps the switch lever and rotates the switch shaft counterclockwise, the brake latch moves upward, rotating to the second position and disengaging from the two adjacent teeth of the power gear, releasing the restriction on the rotation of the power gear.

[0067] More preferably, the brake latch is vertically movable within the mounting component. The brake latch has a through groove in its center, and the switch shaft has a connecting rod in its center. The right end of the connecting rod is inserted into the through groove. When the switch shaft rotates clockwise, it causes the right end of the connecting rod to move downwards, thus abutting against the bottom surface of the through groove and pushing the brake latch vertically downwards to the first position. When the switch shaft rotates counterclockwise, it causes the right end of the connecting rod to move upwards, thus abutting against the top surface of the through groove and pushing the brake latch vertically upwards to the first position. In this configuration, the brake latch moves vertically up and down, ensuring precise positioning or release of the power gear.

[0068] Furthermore, velociraptor toys or other four-limbed animals, which have four limbs but only two moving parts, are equivalent to two-limbed animals. Therefore, the mounting part 2 is also provided with two front claws 26; each front claw 26 is respectively set on the front side of a moving part 1, so that it constitutes a four-limbed animal toy, such as a velociraptor toy.

[0069] Furthermore, a balance wheel 27 is rotatably mounted on each of the front claws 26, and the bottom outer surface of the balance wheel 27 is disposed below the bottom of the front claw 26.

[0070] If balance wheels are not installed, counterweights need to be added to the center or rear of the mount to adjust the toy's center of gravity and prevent the velociraptor toy from tipping over during movement. To further prevent tipping and enhance the realism of the velociraptor's movement, balance wheels are mounted on the front paws. During use, the bottom of the balance wheels rests on the ground (taking the toy's movement on the ground as an example). As the two moving parts propel the mount forward in a large stride, the entire mount (body and torso) will exhibit significant ups and downs, better mimicking the running posture of a velociraptor. Therefore, two balance wheels are also installed to assist in body balance and prevent the front paws from touching the ground, thus reducing friction. The balance wheels also provide rolling contact.

[0071] See Figure 4-7 As shown, a counterweight 28 is also provided, which is disposed between the two front claws 26;

[0072] The two ends of the counterweight 28 are respectively connected to the two front claws 26.

[0073] Furthermore, because the moving part (hind leg) experiences a brief period of leg airborne during each step, the entire body (installation unit) is supported by the two front balance wheels and one leg on one side (the moving part on that side), forming a right-angled triangle. At this time, the center of gravity is in the middle of the body, leading to imbalance. See [link / reference needed]. Figure 10 As shown, in the state without counterweights, the center of gravity is located at the center of the mounting component, making it prone to imbalance when the mounting component moves forward. Therefore, counterweights are added, and the closer the counterweight is to the fulcrum (support wheel), the less effort the legs (moving parts) need to exert to propel the body (mounted component). Thus, it is necessary to place the counterweight as close to the fulcrum (balance wheel) as possible without causing interference. In this case, the center of gravity is approximately slightly behind the balance wheel to increase the balance of the motion mechanism during operation. See [link to relevant documentation]. Figure 11 As shown.

[0074] In this embodiment, the front end of the mounting component is provided with a head 4, and the rear end of the mounting component is provided with a tail 5. The mounting component constitutes the body of the velociraptor, the head is the head of the velociraptor, and the tail is the tail of the velociraptor, which is more beautiful and realistic.
