For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] Please refer toFigures 1 to 5 , an operation control structure of the present utility model includes a base body 100. A reversing control module 200, a speed control module 300 and a locking control module 400 are arranged on the base body 100. The reversing control module 200 is provided with a first handle 210, a first rotating shaft 220 and a first runner 230. The first handle 210 is connected to the first runner 230 through the first rotating shaft 220. The first handle 210 is used to drive the first runner 230 to rotate back and forth, so as to send a control instruction for a children's toy such as a toy car. Specifically, a triggering part 231 is arranged on the first runner 230, and an induction module 240 is arranged in the base body 100. The induction module 240 is used to sense the triggering part 231 and send a reversing control instruction. Among them, when the first runner 230 rotates to drive the triggering part 231 to approach the induction module 240, after the induction module 240 senses the triggering part 231, the induction module 240 sends a reversing control instruction for the children's toy.

[0029] The speed control module 300 is arranged on one side of the reversing control module 200. The speed control module 300 is provided with a second handle 310, a second rotating shaft 320 and a second runner 330. The second handle 310 is connected to the second runner 330 through the second rotating shaft 320. The second runner 330 is connected with an encoder 340. The second handle 310 is used to drive the second runner 330 to rotate back and forth, so as to drive the encoder 340 to rotate. As the rotation angle changes, the encoder 340 enables the speed control module 300 to issue speed control instructions with different designed speeds. Among them, the encoder 340 is a sensor that converts the mechanical geometric displacement on the second rotating shaft 320 into pulses or digital quantities through photoelectric conversion. The encoder 340 itself does not involve the inventive point of the present utility model, and the prior art solutions can be adopted to realize the control of the rotation speed of the driving wheel on the children's toy.

[0030] The locking control module 400 is respectively connected to the commutation control module 200 and the speed control module 300. The locking control module 400 includes a third rotating shaft 410 and a first rotating rod 420. The middle part of the first rotating rod 420 is placed on the third rotating shaft 410, and the first rotating rod 420 rotates around the third rotating shaft 410. First limiting wheels 430 and second limiting wheels 440 are respectively arranged at both ends of the first rotating rod 420. An elastic mechanism 450 is arranged on one side of the first rotating shaft 220 close to the first limiting wheel 430. The elastic mechanism 450 is used to apply a force to the first rotating rod 420, so that the first limiting wheel 430 is tightly attached to the first rotating wheel 230. A limiting groove 331 is formed on the second rotating wheel 330. In the initial state, the second limiting wheel 440 is placed in the limiting groove 331. Thus, before the triggering part 231 on the first rotating wheel 230 rotates, the second limiting wheel 440 can effectively limit the second rotating wheel 330, preventing the second rotating wheel 330 from rotating and driving the encoder 340 to move together. Therefore, when the encoder 340 rotates and sends out a speed control instruction, that is, when the commutation control module 200 is in the initial state, the locking control module 400 locks the speed control module 300 to prevent the speed control module 300 from sending out a speed control instruction. The structure of the present utility model separately designs the commutation control module 200, the speed control module 300 and the locking control module 400, and adopts a modular structure combination, with a simple structure, convenient use and simple assembly.

[0031] Further, the triggering part 231 is of a columnar structure. The sensing module 240 is provided with two sensing elastic sheets 241, and the two sensing elastic sheets 241 are respectively arranged on both sides of the triggering part 231. The first handle 210 drives the first rotating wheel 230 to rotate through the first rotating shaft 220, and the triggering part 231 rotates along with the rotation of the first rotating wheel 230. When the triggering part 231 approaches and triggers one of the sensing elastic sheets 241, the sensing module 240 issues a commutation control instruction for forward movement; when the triggering part 231 approaches and triggers the other sensing elastic sheet 241, the sensing module 240 issues a commutation control instruction for backward movement.

[0032] Furthermore, the sensing elastic sheet 241 is arranged below the first rotating wheel 230, and the triggering part 231 extends downward from the surface of the first rotating wheel 230, so that the sensing elastic sheet 241 is on the running path of the triggering part 231, which is convenient for the triggering part 231 to trigger the sensing elastic sheet 241.

[0033] Further, first grooves 232 are respectively arranged on both sides of the trigger portion 231 of the first runner 230. The locking control module 400 further includes a fourth rotating shaft 460 and a second rotating rod 470. One end of the second rotating rod 470 is connected to the fourth rotating shaft 460, and a third limiting wheel 480 is arranged at the other end of the second rotating shaft 320. One end of the elastic mechanism 450 is connected to the second rotating rod 470, and the other end of the elastic mechanism 450 is connected to the first rotating rod 420. The elastic mechanism 450 is further configured to apply a force to the second rotating rod 470, so that the third limiting wheel 480 closely adheres to the first runner 230; a second groove 233 is formed on one side of the first runner 230 away from the first groove 232. In the initial state, the second grooves 233 are respectively arranged on both sides of the first limiting wheel 430. Thus, when the operator rotates the first runner 230 through the first handle 210, after the trigger portion 231 sends a commutation control instruction by triggering the induction elastic sheet 241, the third limiting wheel 480 slides along the edge of the first runner 230 towards the first groove 232 under the action of the elastic mechanism 450, and the first limiting wheel 430 slides along the edge of the first runner 230 towards the second groove 233 under the action of the elastic mechanism 450. The second limiting wheel 440 disengages from the limiting groove 331 under the action of the lever principle, completing the unlocking operation of the locking control module 400 on the speed regulation control module 300. At this time, the operator can rotate the second runner 330 through the second handle 310, and the rotation of the second runner 330 drives the encoder 340 to move together, thereby completing the sending operation of the speed regulation control instruction. That is, after the commutation control module 200 issues a forward or backward commutation control instruction, the locking control module 400 unlocks the speed regulation control module 300, thereby facilitating the operator to complete the speed regulation control effect of the children's toy product through the speed regulation control module 300.

[0034] In one embodiment, a first gear 350 is further arranged on the second rotating shaft 320, and a second gear 360 is arranged on one side of the first gear 350. The first gear 350 and the second gear 360 are meshed. In this embodiment, the first gear 350 is arranged below the second runner 330, and the encoder 340 is arranged on the second gear 360 and rotates along with the rotation of the second gear 360; by adjusting the ratio of the number of teeth of the first gear 350 to the number of teeth of the second gear 360, the rotation speed of the encoder 340 is adjusted, so that the speed regulation control module 300 more accurately issues speed regulation control instructions with different designed speeds.

[0035] In one embodiment, the elastic mechanism 450 is configured as a spring member. Hooks 451 are respectively provided at both ends of the elastic mechanism 450. Hook grooves 401 are respectively provided on the first rotating rod 420 and the second rotating rod 470. The hooks 451 at both ends of the elastic mechanism 450 are respectively placed in the corresponding hook grooves 401 of the first rotating rod 420 and the second rotating rod 470. In the initial state, the spring member is in a stretched state, so as to provide sufficient restoring force to apply a force to the first rotating rod 420 and the second rotating rod 470.

[0036] In one embodiment, a positioning groove 234 is provided between the two second groove portions 233 of the first runner 230. In the initial state, the first limiting wheel 430 is placed in the positioning groove 234, so that the first limiting wheel 430 at one end of the first rotating rod 420 can be stably attached to the first runner 230.

[0037] In one embodiment, the first runner 230 and the second runner 330 are configured as ratchets. After the second limiting wheel 440 is placed in the limiting groove 331, the locking operation of the second runner 330 can be realized, the first limiting wheel 430 can realize the reciprocating sliding operation from the positioning groove 234 to the second groove portion 233, and the third limiting wheel 480 can realize the reciprocating sliding operation between the first groove portions 232.

[0038] In one embodiment, the first handle 210 is configured as a rod. In the initial state, the first handle 210 is placed horizontally. When the first handle 210 swings forward from the initial position, it will drive the first runner 230 to rotate counterclockwise through the first rotating shaft 220, and the trigger portion 231 rotates with the rotation of the first runner 230. When the trigger portion 231 approaches and triggers one of the induction elastic pieces 241, the induction module 240 issues a commutation control instruction for forward movement. When the first handle 210 swings backward from the initial position, it will drive the first runner 230 to rotate clockwise through the first rotating shaft 220, and the trigger portion 231 rotates with the rotation of the first runner 230. When the trigger portion 231 approaches and triggers the other induction elastic piece 241, the induction module 240 issues a commutation control instruction for backward movement, so as to realize the synchronization between the swinging direction of the first handle 210 and the commutation control instruction, and improve the intuitive experience of the operator in controlling the driving direction of the children's toy.

[0039] In one embodiment, the second handle 310 has a disc structure. By rotating the second handle 310, the encoder 340 is gradually driven to rotate. As the encoder 340 rotates, speed control commands with different designed speeds are sent. The larger the rotation angle of the second handle 310, the greater the driving speed corresponding to the speed control command issued by the encoder 340, and the greater the rotational speed of the driving wheel of the children's toy. Thus, the synchronism between the rotation angle of the second handle 310 and the speed control command is achieved, improving the intuitive experience of the operator in controlling the speed of the children's toy.

[0040] In one embodiment, an identification surface 110 is provided on one side of the seat body 100 facing the first handle 210 and the second handle 310. The first runner 230 and the second runner 330 are arranged on the side of the seat body 100 away from the first handle 210 and the second handle 310. The first rotating shaft 220 and the second rotating shaft 320 penetrate through the seat body 100. To facilitate the operator to better send control commands for the children's toy, a forward icon 111 and a backward icon 112 are designed on the identification surface 110 to match the first handle 210, and a speed trend icon 113 is designed on the identification surface 110 to match the second handle 310. Further, a zero speed indication value 114 is also designed on the identification surface 110 to match the second handle 310, thus more conveniently enabling the operator to better complete the reset operation of the speed control command.

[0041] Further, to better send speed control commands with different speed values through the second handle 310, a pointer 370 is provided on the outer side of the second rotating shaft 320 connected to the second handle 310. In the initial state, the pointer 370 points to the zero speed indication value 114 on the identification surface 110. When the operator rotates the second runner 330 through the second handle 310, the pointer 370 rotates synchronously with the rotation of the second runner 330. The farther the pointer 370 is from the zero speed indication value 114, the greater the driving speed corresponding to the speed control command issued by the speed control module 300.

[0042] Specifically, an identification shell 120 is provided on one side of the seat body 100 facing the first handle 210 and the second handle 310. The identification surface 110 is arranged on the identification shell 120. A rotating cylinder 380 is sleeved outside the second rotating shaft 320. The rotating cylinder 380 rotates as the second rotating shaft 320 rotates. The pointer 370 is fixed on the rotating cylinder 380.

[0043] When the present utility model is specifically used, taking the swinging of the first handle 210 towards the forward direction as an example, after the second limiting wheel 440 of the locking control module 400 disengages from the limiting groove 331 of the second runner 330, the operator drives the second runner 330 to rotate through the second handle 310, and then drives the encoder 340 to move together to send a speed control command. The children's toy is in a forward state at a certain speed; at this time, when the operator needs to drive the first runner 230 back to the initial state through the first handle 210, the first limiting wheel 430 needs to disengage from the second groove portion 233 and return to the positioning groove 234. Due to the lever principle, the second limiting wheel 440 needs to return to the limiting groove 331 again. However, since the limiting groove 331 has left the position of the initial state as the second runner 330 rotates, as the operator applies force to the first handle 210, the second limiting wheel 440 gradually approaches and abuts against the edge of the second runner 330. The second limiting wheel 440 is limited by the edge of the second runner 330, thereby preventing the rotation of the first runner 230. The first handle 210 remains in place, that is, when the children's toy is in a forward or backward state with a speed control command at a certain speed, the operator cannot control the commutation control module 200. Only when the children's toy receives a speed control command of zero speed can the operator control the commutation control module 200, effectively avoiding the problem of incompatible control commands caused by the commutation control module 200 and the speed control module 300 being in the control command sending state at the same time. For example, when the children's toy is in a forward running state at a certain speed, due to inertia, it is impossible to suddenly directly switch to a backward running state at a certain speed. The structure of the present utility model separately designs the commutation control module 200, the speed control module 300, and the locking control module 400, and adopts a modular structure combination, with a simple structure, convenient use, and simple assembly.

[0044] In one embodiment, the triggering portion 231 can be correspondingly arranged on one side of the third limiting wheel 480, or can be arranged at other parts of the first runner 230 according to needs. When the operator drives the first runner 230 to rotate through the first handle 210, the triggering portion 231 is at the designed position of the first runner 230 on the premise of not affecting the back-and-forth sliding operation of the third limiting wheel 480 between the first groove portions 232; for example, the triggering portion 231 can be arranged between the first groove portion 232 and the second groove portion 233. The two sensing elastic pieces 241 of the sensing module 240 are synchronously arranged on both sides of the triggering portion 231. The sensing module 240 sends out a forward or backward commutation control command according to the different rotation directions of the first runner 230.

[0045] In one embodiment, the seat body 100 includes an upper panel 101 and a lower panel 102. The first rotating shaft 220 and the second rotating shaft 320 are both fixed to the upper panel 101 and the lower panel 102 through bearings. The first runner 230 and the second runner 330 are arranged between the upper panel 101 and the lower panel 102. The second gear 360 is fixed to the lower panel 102 through a fifth rotating shaft 390.

[0046] In other embodiments, alternatively, the trigger portion 231 protrudes from the first runner 230. The sensing module 240 includes two groups of photoelectric proximity switches. Each group of photoelectric proximity switches includes a light emitter and a light receiver. The two groups of photoelectric proximity switches are respectively arranged on both sides of the trigger portion 231. In the initial state, the light emitted by the light emitter can pass through the edge of the first runner 230 and be received by the light receiver. When the trigger portion 231 rotates along with the first runner 230 in one direction, after the trigger portion 231 blocks one side of the photoelectric proximity switch, the light receiver of the photoelectric proximity switch on the other side can still receive the light signal, thereby sending out a commutation control instruction for forward movement; when the trigger portion 231 rotates along with the first runner 230 in the other direction, after the trigger portion 231 blocks the photoelectric proximity switch on the other side, the light receiver of the photoelectric proximity switch on one side can still receive the light signal, thereby sending out a commutation control instruction for backward movement.

[0047] When the utility model works specifically, in the initial state, the second limiting wheel 440 is placed in the limiting groove 331. Thus, when an operator rotates the second runner 330 through the second handle 310, the second limiting wheel 440 can effectively limit the second runner 330, preventing the second runner 330 from rotating and driving the encoder 340 to move together, thereby avoiding the encoder 340 from rotating and sending out a speed regulation control instruction. That is, when the commutation control module 200 is in the initial state, the locking control module 400 locks the speed regulation control module 300 to prevent the speed regulation control module 300 from sending out a speed regulation control instruction. Taking the example that the operator rotates the first runner 230 upward through the first handle 210, after the triggering part 231 rotates counterclockwise to trigger the induction elastic sheet 241 on its left side to send out a forward commutation control instruction, the third limiting wheel 480 slides along the edge of the first runner 230 to the right side of the triggering part 231, i.e., the first groove part 232, under the action of the elastic mechanism 450, and the first limiting wheel 430 slides along the edge of the first runner 230 to the second groove part 233 under the action of the elastic mechanism 450. The second limiting wheel 440 disengages from the limiting groove 331 under the action of the lever principle, completing the unlocking operation of the locking control module 400 on the speed regulation control module 300. At this time, the operator can rotate the second runner 330 through the second handle 310, and the rotation of the second runner 330 drives the encoder 340 to move together, thereby completing the sending operation of the speed regulation control instruction for the forward movement of the children's toy. Limited by the fact that the second limiting wheel 440 is limited by the edge of the second runner 330, when the children's toy is in the running state, the second limiting wheel 440 cannot return to the limiting groove 331, and further, the first limiting wheel 430 cannot disengage from the second groove part 233. When the operator needs to re-implement the commutation control of the children's toy, i.e., control the children's toy to move backward, through the first handle 210, the second runner 330 is first rotated to make the second limiting wheel 440 return to the limiting groove 331. At this time, the speed regulation control module 300 sends a speed regulation control instruction of zero speed to the children's toy, and then the operator rotates the first runner 230 downward through the first handle 210, thereby completing the sending operation of the speed regulation control instruction for the backward movement of the children's toy.

[0048] In summary, an operation control structure of the present utility model sets a commutation control module 200, a speed regulation control module 300 and a locking control module 400 on a seat body 100. The commutation control module 200 is provided with a first handle 210, a first rotating shaft 220 and a first runner 230. The speed regulation control module 300 is provided with a second handle 310, a second rotating shaft 320 and a second runner 330. The induction module 240 is configured to sense a trigger portion 231 on the first runner 230 to send a commutation control instruction, and an encoder 340 is connected to the second runner 330 to send a speed regulation control instruction. The locking control module 400 is combined to lock or unlock the speed regulation control module 300. Thus, when the commutation control module 200 is in an initial state, the locking control module 400 locks the speed regulation control module 300 to avoid the speed regulation control module 300 from sending a speed regulation control instruction. The structure of the present utility model separately designs the commutation control module 200, the speed regulation control module 300 and the locking control module 400, and adopts a modular structure combination, with a simple structure, convenient use and simple assembly.
