[0027] A turnstile clutch is used to control the opening and closing of a turnstile. Conventional turnstile clutches often employ a clutch disc, which consists of two or more plates and engages and disengages power through friction. This method requires high assembly precision, and during control, it only allows selection of lock and unlock modes, which limits its application scenarios.
[0028] To address the issues in the relevant technologies, the following will be discussed in conjunction with... Figures 1-3This invention describes a throttle clutch, comprising a housing 10, a clutch disc 20, a stator 40, and a rotor 50. The clutch disc 20 is connected to the housing 10 and forms an assembly space inside. A through hole 24 for a main shaft 30 to pass through is provided in the center of the clutch disc 20. At least one limiting notch 21 is provided on the side wall of the edge of the through hole 24. A movable sleeve 23 is provided within the limiting notch 21, and the movable sleeve 23 can selectively contact and abut against the main shaft 30. The stator 40 is disposed within the assembly space and fixedly connected to the clutch disc 20. The rotor 50 is sleeved on the stator. Inside rotor 50, the outer wall surface at the bottom is provided with actuating components 60 corresponding to the limiting notches 21. The distance between the sidewall of the limiting notch 21 and the edge of the through hole 24 gradually decreases as the sidewall extends from the center to both sides, forming an idle position 213 in the center of the limiting notch 21. A first locked position 211 and a second locked position 212 are formed on both sides of the idle position 213. The actuating components 60 are used to drive the movable sleeve 23 to switch between the first locked position 211, the second locked position 212, and the idle position 213. A clutch is used to control the rotation of the main shaft 30, achieving the locking of the main shaft 30 and controlling the required rotation angle. In this embodiment, the movable sleeve 23 is located within the limiting notch 21, and the movable sleeve 23 can contact and abut against the main shaft 30 to lock the main shaft 30. It can also switch between the first locked position 211, the second locked position 212 and the idle position 213 under the drive of rotation, which enriches the application scenarios of the clutch, and the assembly accuracy requirements can be reduced by contacting and abutting.
[0029] Specifically, the housing 10 has a cylindrical structure, and a through hole 24 is provided in the middle of the housing 10 for the main shaft 30 to pass through. The housing 10 is connected to the clutch disc 20 by bolts to form an assembly space inside the housing 10, so that the stator 40 and the rotor 50 can be arranged in the assembly space.
[0030] The clutch disc 20 has a disc-shaped structure. The through hole 24 in the middle of the clutch disc 20 is used for the main shaft 30 to pass through. The clutch disc 20 also has multiple bolt holes, which are used to fix the stator 40 to the clutch disc 20. The stator 40 is the stator 40 structure in a conventional motor. Similarly, the rotor 50 is also the rotor 50 structure in a conventional motor.
[0031] For example, it can be a disc motor structure, with multiple windings inside the stator 40 and permanent magnets on the rotor 50, thus forming an internal rotor 50 motor structure. This allows the rotor 50 to rotate relative to the stator 40 after being energized, thereby driving the movable sleeve 23 to rotate. This enables the movable sleeve 23 to contact and abut against the main shaft 30. When the main shaft 30 and the movable sleeve 23 are in contact, the main shaft 30 can be locked. When the movable sleeve 23 is in the idling position 213, the movable sleeve 23 does not contact the main shaft 30, thus preventing the main shaft 30 from being locked.
[0032] Understandably, the main shaft 30 typically rotates under the drive of external power, and the clutch needs to control the rotation of the main shaft 30 (locking or idling). In this embodiment, the movable sleeve 23 has actuating positions at the center and on both sides of the limiting notch 21. That is, when the movable sleeve 23 is in the center position, the distance between the side wall of the limiting notch 21 and the edge of the through hole 24 is the farthest, allowing the main shaft 30 to idle. When in the left or right side positions, the movable sleeve 23 is squeezed and shifted towards the center of the through hole 24, thereby bringing the movable sleeve 23 closer to the main shaft 30 and locking the main shaft 30. It should be noted that the movable sleeve 23 is connected by the actuating assembly 60, and it can shift to a certain extent under the action of the limiting notch 21, thereby locking the main shaft 30.
[0033] In some embodiments, an auxiliary notch 11 is provided on the edge of the end where the housing 10 connects to the clutch disc 20, and the auxiliary notch 11 is correspondingly provided with the limiting notch 21. The auxiliary notch 11 is provided so that the internal situation can be observed from the outside, so as to realize real-time feedback.
[0034] Specifically, the auxiliary notch 11 is formed on the housing 10 and is located at the position corresponding to a limiting notch 21. This allows the external observer to observe the operation of the internal toggle assembly 60 through the auxiliary notch 11, which is convenient for observation during testing and maintenance.
[0035] According to the embodiment provided by this utility model, the actuating assembly 60 includes a connecting part 61 and a lever 62. The connecting part 61 is connected to the rotor 50, and one end of the lever 62 is connected to the connecting part 61, while the other end of the lever 62 is inserted into the movable sleeve 23. The connecting part 61 is connected to the rotor 50, and the lever 62 is disposed on the connecting part 61, so that when the rotor 50 rotates, the lever 62 can drive the movable sleeve 23 to make a circular motion. When it moves to make a circular rotation, it will be radially offset along the through hole 24 under the action of the side wall of the limiting notch 21, thereby achieving locking.
[0036] Specifically, in this embodiment, when the lever 62 is in the middle position of the limiting notch 21, the main shaft 30 is in a free, idling state. When the rotor 50 rotates forward (clockwise rotation is defined as forward rotation), the movable sleeve 23 rotates to the first locked position 211, thereby achieving forward locking of the main shaft 30. Similarly, when the rotor 50 rotates counterclockwise (counterclockwise rotation is reverse rotation), the movable sleeve 23 rotates from the middle idling position 213 to the second locked position 212, thereby achieving reverse locking of the main shaft 30. That is, the forward locking position, reverse locking position, and idling position 213 can be configured in the mode configuration, enriching the clutch mode design and improving its applicability.
[0037] In some embodiments, the minimum diameter of the auxiliary notch 11 is greater than or equal to the maximum diameter of the limiting notch 21; at least one connecting portion 61 has a protrusion 611 located within the auxiliary notch 11. The auxiliary notch 11 corresponds to the limiting notch 21, and the position of the clutch rotor 50 can be observed through the auxiliary notch 11. In this embodiment, the size limitation of the auxiliary notch 11 can prevent interference between the protrusion 611 and the auxiliary notch 11 during rotation of the rotating assembly, thereby affecting the control of the rotation of the main shaft 30.
[0038] In some embodiments, a positioning notch 22 is also provided on the outer edge of the clutch disc 20. The positioning notch 22 is located within the auxiliary notch 11 and at the center of the limiting notch 21. A magnetic suction part 221 is provided within the positioning notch 22. Considering that power outages may occur in some emergency situations, in this embodiment, the magnetic suction part 221 is provided so that the movable sleeve 23 can be maintained in the free-spinning position 213 in the event of a power outage, thereby preventing the spindle 30 from locking up and becoming unable to rotate in special circumstances such as a power outage.
[0039] Specifically, such as Figure 2 , Figure 3 As shown, a magnetic suction part 221 is provided in the positioning notch 22, and the corresponding protrusion 611 is made of metal material, or a magnetic suction element is also provided on the protrusion 611. The magnetic suction part 221 and the magnetic suction element in the positioning notch 22 are opposite magnets, so that the movable sleeve 23 can be kept in the free-spinning position 213 under the mutual magnetic attraction, ensuring that the spindle 30 can rotate freely in the event of power failure.
[0040] It is understandable that turnstiles are typically used in public transportation, stadiums, parking lots, and other places where people need to be evacuated as quickly as possible in the event of a power outage. In this embodiment, by providing a protrusion 611 at the connection point, and the protrusion 611 being located within the auxiliary notch 11, the protrusion 611 can be maintained at the idle position 213 of the main shaft 30 under the action of the magnetic attraction part 221, thereby preventing the turnstile from locking and enabling the turnstile to be opened quickly.
[0041] In some embodiments, the connecting part 61 is integrally formed with the rotor 50. The connecting part 61 is located at the bottom of the rotor 50 and is used to support the lever 62. The integral forming method can improve the overall structural strength and ensure the stability of the device.
[0042] According to the gate clutch provided by this utility model, such as Figure 3 As shown, the connecting part 61 is provided with an internal threaded hole, and a corresponding external thread is provided on one end of the lever 62, so that the lever 62 is threadedly connected to the connecting part 61. The threaded connection between the lever 62 and the connecting part 61 can improve its assembly efficiency and achieve efficient assembly. Moreover, the threaded connection allows for a certain amount of offset when the movable sleeve 23 is moved, so that the movable sleeve 23 can be offset toward the main shaft 30, thereby achieving locking of the main shaft 30.
[0043] Specifically, the lever 62 can be made of hard plastic, so that the lever 62 has high strength and can undergo a certain elastic deformation, thereby achieving a small displacement under the action of the limiting notch 21, and locking the main shaft 30.
[0044] For example, the lever 62 can be made of carbon fiber, and the lever 62 can deform within its elastic limit to offset under the action of the side wall of the limiting notch 21. Of course, the lever 62 can also be made of metal. When the metal rod is fixed at one end and suspended at the other end, it can also generate a certain amount of deformation when compressed, thereby achieving locking of the main shaft 30.
[0045] In some embodiments, a first bearing 12 connected to one end of the main shaft 30 is provided at the top inside the housing 10. The main shaft 30 extends through the entire clutch, and the connection between the main shaft 30 and the bearing enables a stable connection of the main shaft 30 and smooth rotation of the main shaft 30.
[0046] In some embodiments, the clutch disc 20 has an end cap 80 at its bottom, and the end cap 80 contains a second bearing 81 for connection with the main shaft 30. The end cap 80 supports the other end of the main shaft 30, thereby enabling the rotation of the main shaft 30 and supporting the main shaft 30.
[0047] Specifically, the end cover 80 is connected to the clutch disc 20 by bolts, and the surface of the end cover 80 serves as the bottom surface of the limiting notch 21. The movable sleeve 23 is placed inside the limiting notch 21. In other words, the movable sleeve 23 and the limiting notch 21 have no physical connection. It is only necessary to place the movable sleeve 23 inside the limiting notch 21. This solves the defects of high precision requirements and difficult assembly in related technologies.
[0048] According to the embodiment provided by this utility model, it also includes a control main board 70, which is disposed in the assembly space and electrically connected to the stator 40. The main control board is used to output control signals to control the rotation direction and whether the rotor 50 rotates.
[0049] It is understandable that the control motherboard 70 is a PCB board. By placing the control motherboard 70 in the assembly space, the overall structure can be made more compact. The control motherboard 70 can be set up to output control signals and control the rotation of the rotor 50.
[0050] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment, through the setting of the limiting notch 21 and the movable sleeve 23, can achieve locking when the movable sleeve 23 is on both sides of the limiting notch 21, allowing it to switch between the first locked position 211, the second locked position 212, and the idle position 213 under the drive of the rotor 50, thus enriching its working modes and application scenarios. Furthermore, the setting of the auxiliary notch 11 enables the observation of the rotation state of the rotor 50 for testing or maintenance, and the magnetic suction part 221 enables the main shaft 30 to be kept in the idle position 213 in the power-off state, which can improve the reliability of the system, ensure personnel safety, facilitate later maintenance, and also reduce the risk of equipment damage.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
