Description

Technical Field

[0001] The utility model discloses an educational toy for infants, in particular to an educational toy for training the balance of infants. Background Art

[0002] When young children first start to practice upright walking, they are prone to falls and bumps due to lack of sense of balance. Therefore, they need to use some balance chairs to help young children walk upright and find a sense of balance.

[0003] Publication number CN216456839U is a Chinese utility model patent, which discloses a toy for children to develop intelligence, belonging to the technical field of intelligence development toys, including a base, on which an intelligence development toy device is arranged. The utility model combines the traditional small games that rely on gravity to operate with a balance platform that relies on balance, which can achieve the training of body balance, and at the same time, the maze can be designed by oneself, which can exercise the brain. As long as a person stands on it, he can rely on the control of body balance to shuttle the ball through the maze until it reaches the destination.

[0004] In combination with the above structure, in the above structure, the sense of balance of the young child is trained by combining the small games on the base with the balance platform, but the above structure is limited to one area. In the balance training, it is easier for the young child to walk on the ground by himself to help the sense of balance. Moreover, for most young children who are curious about things in the outside world and like to move around, being confined to one area can easily make the young child feel bored and it is difficult to produce the effect of training. Moreover, as the child grows up, the balance car used for balance training is prone to be idle. Therefore, it is necessary to develop a toy that can provide young children with a sense of balance and can also provide young children with educational and entertaining toys. Utility Model Content

A guide wheel 33 is respectively provided on the side; one of the two clamping plates 4 is provided with an arc-shaped guide rail 40, and one of the two clamping plates 4 is provided with an air cylinder 42, one end of the air cylinder 42 is connected to a push rod 44, the push rod 44 is connected to a swing rod 45, and the swing rod is connected to the broken end of a shaft rod 51, and a rotating motor 41 is provided in the other clamping plate 4, and the rotating motor 41 is connected to the other end of the shaft rod 51, and the end of the rotating motor 41 away from the shaft rod 51 adopts the mutual connection of the rotating shaft and the shaft rod, and is fixed in the other clamping plate 4; the shaft rod 51 pushes the push rod and the swing rod 45 through the air cylinder 42, and reciprocates in one direction along the arc-shaped guide rail 40, and the other end of the shaft rod 51 swings back and forth along the moving direction of the shaft rod 51 through the mutual cooperation of the connected shaft sleeve and the shaft rod.

[0028] The present invention fixes the child in the frame 1 through the fixing belt set 6 in the frame 1, and the fixing belt set 6 can prevent the child from being subjected to the impact force fed back by the frame 1 after the frame 1 is hit when the child is moving, and the fixing belt set 6 has a certain elasticity and softness, which can fully wrap the body of the child, so that the present invention can be applied to children of different physiques. In normal conditions, the child is fixed on the frame 1 and the fixing belt set 6 and can move freely, and the frame 1 and the two side panels 3 can provide a certain balance assistance, so as to calmly prevent the child from swinging in one direction due to insufficient sense of balance during the free movement, and because the child The child's body is wrapped by the fixing belt group 6. Therefore, in the event of a fall, the child can avoid falling by pulling the fixing belt group, and also avoid bumping against the edge of the frame 1. When the child is not undergoing balance training, the utility model can start the driving wheel 5 between the two clamping plates 4, and the driving wheel 5 provides kinetic energy for moving back and forth, so that the utility model can be set in the form of a car model toy, and the driving wheel 5 can be pushed forward and backward by the cooperation of the air cylinder 42 and the push rod 44, so as to realize the swing of the driving wheel 5. After the driving wheel 5 swings, the steering of the utility model in the form of a car model toy is realized.

[0029] After adopting the above structure, it needs to be further explained that the frame 1 and the connecting plate 2 of the utility model are connected and fixed, and a connecting rod is provided on the side opposite to the connecting plate 2, and the connecting rod is used to connect with the external pull rod or traction rope. This arrangement can be used as a push baby carriage when the pull rod is connected, and when the connecting rod of the utility model is wrapped around the traction rope, the utility model can prevent the child from leaving the restricted area when the child uses and moves the utility model.

[0030] The connection plate 2 can provide support in the front, so that when the two side plates 3 and the connection plate 2 are erected on the ground, they form a triangular support, and the connection plate 2 can also be used as a front impact force, so that the connection plate 2 can block foreign objects in the front to a certain extent.

[0031] A gap is provided between the two clamping plates 4 and the driving wheel 5, and the gap is used to provide the driving wheel 5 with left and right movement and to swing left and right along the center of the driving wheel 5. When the driving wheel 5 is swung left and right, the driving wheel 5 turns in the swinging direction during the rotation process and drives the frame 1 and the two side plates 3.

[0032] The utility model not only provides a new balance model for children, but also provides the use of a mobile car toy for children. When the children drive the utility model, the utility model can also provide the children with educational and fun activities for exercising their sense of direction.

[0033] Two through holes are respectively provided on both sides of the frame 1, and a limit rod 11 is passed through each through hole. The lower end of each limit rod 11 is fixedly connected to the top of the side plate 3. A threaded hole is provided between the two through holes. A threaded rod 12 is meshed and connected in the threaded hole of the frame 1. A turntable is provided at one end of the threaded rod 12 connected to the guide plate 31, and the threaded rod 12 is connected to the guide plate 31 by a turntable; the guide plate 31 moves back and forth up and down through the two limit rods 11 and a threaded rod 12.

[0034] After adopting the above structure, it needs to be further explained that when the utility model needs to be adjusted according to the height of the child, the threaded rod 12 can be engaged. Through the engagement and movement of the threaded rod 12, the gap between the side panel 3 and the frame 1 can be widened or narrowed. When the side panel 3 contacts the ground, the frame 1 can be moved away from or closer to the ground, thereby achieving height adjustment.

[0035] When the threaded rod 12 is engaged to adjust the height, in order to avoid the swing between the frame 1 and the side plate 3 during the engagement and rotation, the limiting function is achieved.

[0036] A vertical plate is extended below each side plate 3, a groove matching the vertical plate arranged on the side plate 3 is provided above the guide plate 31, and a buffer spring is connected between the side plate 3 and the guide plate 31 and on opposite sides respectively; two grooves are provided below the guide plate 31, and an embedding opening is provided in each groove; an embedding block is provided above the two guide wheels 33 arranged below the guide plate 31, and the two guide wheels 33 are respectively placed in each groove, and are embedded in a corresponding embedding opening using an embedding block.

[0037] After adopting the above structure, it needs to be further explained that the two guide wheels 33 below the guide plate 31 are fixed by embedding, so that when one of the guide wheels 33 is damaged, it can be quickly replaced by pulling.

[0038] The springs arranged between the side panels 3 and the guide panels 31 can avoid vibration feedback during the movement of the utility model, and can minimize vibration feedback during the movement. The vertical panels below the side panels 3 are embedded in the grooves of the guide panels 31, and are used to limit the connection between the guide panels 31 and the side panels 3. When the guide panels 31 vibrate, the feedback vibration is buffered by the buffer springs, and the vertical panels below the side panels 3 are embedded in the grooves of the guide panels 31, and can avoid displacement from the side panels 3 when the guide panels 31 vibrate.

[0039] A control unit 23 is provided in the connecting plate 2; an extension tube is provided above the connecting plate 2 and on one side facing the frame 1, and is connected to the steering wheel 7 through the extension tube, and a collar is provided at one end of the steering wheel 7 connected to the extension tube, and a connecting rod 71 is provided at one end of the steering wheel 7 facing the extension tube, and the connecting rod 71 passes through the extension tube and extends into the connecting plate 2; a contact plate 72 is provided at one end of the connecting rod 71 extending into the connecting plate 2, and a spring is provided at both ends of the contact plate 72 and between the upper side and the inside of the connecting plate 2; the two ends of the contact plate 72 are respectively bent vertically downward, A touch plate 74 is provided below the two vertical ends of the contact plate 72; an exhaust fan 21 is provided inside the connecting plate 2, and the exhaust port of the exhaust fan 21 is passed through the outside of the connecting plate 2, and an air pump 210 is connected to the other side of the exhaust fan 21, and at least two air pumps 210 are provided, and the two air pumps 210 are connected to the air cylinders 42 respectively; the contact plate 72, the exhaust fan 21 and the air pump 210 are respectively connected to the control unit 23 by wire pipes, and are electrically connected, and the other side of the control unit 23 is connected to a push switch 22 by a wire pipe, and the push switch 22 is embedded in the outside of the connecting plate 2.

[0040] After adopting the above structure, it needs to be further explained that the control unit 23 adopted in the utility model is composed of a combination of several circuit boards and a reserve power supply, wherein the several circuit boards are electrically connected to the reserve power supply, and the reserve power supply is electrically connected to the external power supply by using a wire tube to store electrical energy in the reserve power supply, and the several circuit boards of the control unit 23 are used to control the start and stop of the electrical components of the utility model, and the power supply of the control unit 23 of the utility model is connected to the self-contained power supply through the press switch 22. Therefore, the electrical connection / disconnection between the several circuit boards of the control unit 23 and the self-contained power supply can be realized by pressing the start and stop of the switch 22, and the electrical components of the utility model can be started and stopped only after the control unit 23 is powered on.

[0041] By swinging the steering wheel 7, the steering wheel 7 rotates the connecting rod 71, wherein the connecting rod 71 rotates to the left / right side for a certain period of time, which drives one end of the contact plate 72 to swing downward, and allows the swinging vertical bending end to contact the touch plate 74 below, and the touch plate 74 receives the left / right touch feedback of the contact plate 72, and transmits the feedback information to the control unit 23 through the wire pipe, and the control unit 23 starts one of the two air pumps 210, and the two air pumps 210 are respectively an exhaust air pump and an injection air pump, and the two air pumps 210 correspond to two pedals 24 respectively, and by pressing the two pedals 24, the corresponding two air pumps are suctioned or injected; when one of the two pedals 24 is pressed, the utility model starts the exhaust air pump to extract the gas inside the air cylinder 42, and when the other pedal 24 is pressed, the injection air pump is started, and the gas introduced by the exhaust fan 21 is injected into the air cylinder 42.

[0042] The exhaust fan 21 is used to extract the outside air and introduce it into the air injection pump, and also to attack the gas extracted from the air cylinder 42 by the exhaust pump and discharge it through the air outlet of the exhaust fan 21.

[0043] The connecting plate 2 faces one side of the frame 1, and two pedals 24 are provided below; two convex plates are provided at one edge of each pedal 24, a convex column is provided on the side adjacent to the pedal 24, and the convex column is provided between the two convex plates, and a convex block is provided on one side of each convex plate close to the convex column, and each convex plate is embedded in one end of the convex column through the convex block, and the pedal 24 swings in a fan shape in one direction along the axis of the convex column through the cooperation between the two convex plates and a convex column, and a limit plate is provided below the pedal 24, and the pedal 24 is placed above the limit plate. ; A slot is provided in each pedal 24 and on one side facing the connecting plate 2, a sensing plate is provided in the slot, a pressing plate 241 is provided obliquely above the pedal 24, one end of the pressing plate 241 is connected to the edge of the pedal 24 by a rotating shaft, the other end of the pressing plate 241 is inclined upward, and the upper end of the pressing plate 241 is flush with the edge of the slot, a pressing spring is provided between the upper end of the pressing plate 241 and the sensing plate; the sensing plate of each pedal 24 is electrically connected to the control unit 23 by a wire tube.

[0044] After adopting the above structure, it needs to be further explained that the sensing plate adopted in the utility model is a contact sensing plate, which is pressed toward the surface of the sensing plate by the external force through the pressing plate 241 (a soft pad is provided on the side where the pressing plate 241 contacts the surface of the sensing plate, and the soft pad prevents the pressing plate 241 from damaging / scratching the sensing plate due to the pressing force exerted on the sensing plate). After the sensing plate receives the pressing feedback from the pressing plate 241, the information is transmitted to the control unit 23 through the wire pipe, and then the operation of the injection pump or the exhaust pump is started and stopped by the control unit 23.

[0045] In order to prevent the pedal 24 from accidentally touching the pressing plate 241 of the pedal 24 or hindering the movement of the child in the frame 1 when it is not practical, the pedal 24 of the utility model can be folded toward the connecting plate 2 through the cooperation between two convex plates and a convex column, further ensuring that the pedal 24 can remain in the folded state, a plurality of magnets are provided at the edge of the pedal 24, and a magnetic metal plate is provided on the corresponding side of the connecting plate 2, and the pedal 24 is fixed by being adsorbed on the surface of the magnetic metal plate of the connecting plate 2 by the plurality of magnets.

[0046] The pedal 24 is used not only to control the start and stop of the two air pumps, but also to provide support for the footsteps of the child when the utility model is in the form of a car model toy. The child's feet are supported by stepping on the edges of the corresponding pedals 24. This arrangement can also prevent the forward momentum from pulling the child's footsteps when the car model toy is moved.

[0047] The air cylinder 42 is hollow inside, and one end of the air cylinder 42 is connected to the air pump 210 by a wire tube; the other end of the air cylinder 43 is penetrated by one end of a push rod 44, and a blocking block 440 is provided at this end of the push rod 44. A gasket is provided on the side of the air cylinder 43 facing the air pump 210, and a spring is provided between the gasket of the air cylinder 43 and the blocking block 440; the end of the push rod 44 away from the air cylinder 42 is connected to one end of the swing rod 45 by a pin, and the width of the end of the push rod 44 connected to the swing rod 45 is smaller than the width of the connecting end of the swing rod 45, and a stop rod 450 is provided on the opposite sides of the end of the swing rod 45 connected to the push rod 44, and relative to the opposite sides of the push rod 44.

[0048] After adopting the above structure, it needs to be further explained that the air cylinder 42 is injected with air to push the push rod 44 / exhausted with air to pull the push rod 44 through two air pumps 210. In order to ensure the gas leakage inside the air cylinder 42, a blocking block 440 is provided at one end of the push rod 44 inserted into the air cylinder 42. The edge of the blocking block 440 is attached to the inner wall of the air cylinder 42 and is tightly attached to the inside of the air cylinder 42. The blocking block 440 is pulled or pushed by the exhaust air pump and the injection air pump respectively to move the push rod 44 forward or backward.

[0049] The spring arranged inside the air cylinder 43 is used to pull or push out the blocking block 440. When the air injection pump injects gas into the air cylinder 43, the blocking block 440 is pushed forward and pulls the spring. When the air extraction pump extracts gas into the air cylinder 43, the blocking block 440 squeezes the spring. When no air injection or extraction is performed, the spring is reset to a normal state (without pulling or squeezing deformation). This arrangement can push or pull the blocking block 440 to a limited area through the spring when no gas is injected or extracted in the air cylinder 43, and can reset the direction of the guide wheel 5 when the air cylinder 43 is idle, thereby avoiding the need for manual correction of the direction during movement, and reducing the need for young children to use weak strength to avoid the use of force to correct or correct the moving direction.

[0050] Under the push of the top rod 44, the swing rod 45 is driven forward or backward, and the swing rod 45 is connected to one end of the shaft rod 51 by an axial column. The end of the swing rod 45 connected to the shaft rod 51 moves along the direction of the guide rail 40, wherein the arc-shaped setting of the guide rail 40 allows the end of the shaft rod 51 to swing at a larger angle, thereby allowing the driving wheel 5 to swing at a larger angle and increase the steering angle.

[0051] After the swing rod 45 fixes the shaft rod 51 through the sliding block, it swings along the direction of the arc-shaped guide rail 40. Therefore, a pin is used to connect the push rod 44 and the swing rod 45 so that when the push rod 44 is pushed out in one direction, the swing rod 45 is pushed out. Since the swing rod 45 can swing left and right, when the push rod 44 is pushed out, the swing rod 45 can also move along the guide rail 40. Finally, in order to prevent the swing rod 45 from swinging too much, the swing rod 45 is connected to the push rod 44, and baffles 450 are respectively provided on the opposite sides, so that the swing rod 45 can swing along the amplitude between the two baffles 450.

[0052] The width of the top rod 44 is smaller than that of the swing rod 45 , so as to provide sufficient swing space for the swing rod 45 .

[0053] In the above arrangement, the two pedals 24 are controlled by the legs to turn the rotating motor 41 forward and backward respectively, so that the rotating motor 41 (the rotating motor 41 of the utility model can rotate forward and reverse, and the forward and reverse rotations are controlled by the two pedals 24 respectively), and the two air pumps are used to push out or pull the push rod, so that the shaft rod 51 can swing forward and backward, thereby realizing the direction adjustment during the movement. In order to ensure the strength of the swinging reverse wheel of the child, the utility model allows the child to swing the steering wheel 7 to allow the steering wheel 7 to rotate.
