Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a transmission device with automatic clutch function. Background Technology

[0002] In existing power-driven valve / knob devices, the motor and actuator are usually rigidly coupled. This means that when operating manually, users have to overcome a great deal of static friction and back EMF resistance from the motor, resulting in a poor user experience and difficult operation. To solve this problem, some designs have introduced an external clutch mechanism, but this has led to new problems such as complex structure, high cost, reduced reliability, and large size.

[0003] Therefore, the market urgently needs a transmission solution that can intelligently switch drive modes. It must ensure a firm connection during power transmission and achieve a near-zero resistance separation during manual operation, thus balancing automation efficiency with the convenience of manual operation. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Furthermore, the second transmission component is a sleeve fitted onto the outer circumferential surface of the connecting rod. The two ends of the sleeve are respectively formed with an annulus and a contact block. A second limiting annulus groove is opened in the middle of the outer shell.

[0011] Furthermore, the reset assembly includes a contact ring slidably connected within the second limiting ring groove, a spring fixedly connected between the contact ring and the second limiting ring groove, and the contact ring contacting the circular ring.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A transmission device with automatic clutch function includes a housing 1, a first transmission member 2 and a driving member 3 for driving the first transmission member 2 to move are provided inside the housing 1, a second transmission member 4 for cooperating with the first transmission member 2 is provided on one side of the first transmission member 2, a reset component 5 for resetting the second transmission member 4 is provided inside the housing 1, and a third transmission member 6 is also installed on one side of the housing 1.

[0021] The first transmission component 2, the driving component 3, the second transmission component 4, the reset component 5, and the third transmission component 6 are all symmetrically designed and can automatically engage and disengage from both sides.

[0022] It should be noted that the driving component 3 includes a motor 31 fixedly installed inside the housing 1. A connecting rod 32 is fixedly connected to the shaft end of the motor 31. A contact groove 33 is provided on the circumferential surface of the connecting rod 32. The motor 31 drives the connecting rod 32 to rotate.

[0023] In this embodiment, the first transmission component 2 is a disc 21. A first limiting annular groove 11 is provided on one side of the inner side of the outer shell 1. The disc 21 is rotatably connected in the first limiting annular groove 11. A hole 22 adapted to the connecting rod 32 is provided in the middle of the disc 21. A limiting block 23 that contacts the contact groove 33 is formed on one side of the hole 22. The connecting rod 32 is slidably connected to the hole 22. An annular inclined surface 24 is formed on the outer peripheral surface of one end of the disc 21.

[0024] The hole 22 is slidably connected to the connecting rod 32, and then the contact groove 33 and the limiting block 23 come into contact, thereby circumferentially locking the disc 21 and the connecting rod 32. During the rotation of the connecting rod 32, the disc 21 will also rotate, and the first limiting ring groove 11 will limit the disc 21 to a fixed position so that it will not move.

[0025] Furthermore, the second transmission component 4 is a sleeve 41 sleeved on the outer circumference of the connecting rod 32. The two ends of the sleeve 41 are respectively formed with a ring 42 and a contact block 43. A second limiting ring groove 12 is opened in the middle of the outer shell 1. The ring 42 is rotatably connected to the second limiting ring groove 12. The contact block 43 contacts the annular inclined surface 24. Teeth 44 are formed on the outer side of the ring 42.

[0026] The second limiting ring groove 12 has a space inside for the translation of the second transmission member 4. During use, when the first transmission member 2 is rotated by the driving member 3, the annular inclined surface 24 will contact the contact block 43, thereby moving and rotating the second transmission member 4 as a whole. After the second transmission member 4 moves to the corresponding position, the teeth 44 on the ring 42 and the output member 61 mesh with each other, thereby driving the third transmission member 6 to rotate through the second transmission member 4. It should be noted that in this embodiment, the annular inclined surface 24 and the contact block 43 are preferably two, and the teeth 44 are two on the ring 42 and two on the output member 61.

[0027] The reset component 5 includes a contact ring 51 that is slidably connected in the second limiting ring groove 12. A spring 52 is fixedly connected between the contact ring 51 and the second limiting ring groove 12. The contact ring 51 is in contact with the ring 42.

[0028] When manual adjustment is required, the motor 31 reverses to move the annular inclined plane 24 into the gap between the two contact blocks 43. Then, the tension of the spring 52 causes the contact ring 51 to contact the ring 42, moving the ring 42 and separating the teeth 44. The third transmission component 6 can then be rotated by hand without affecting other transmission components.

[0029] Based on the above embodiments, the third transmission component 6 is an output component 61, which is rotatably connected to the connecting rod 32. The output component 61 also has teeth 44 formed on one side, and the teeth 44 mesh with each other. The outer shell 1 has a third limiting ring groove 13, and the output component 61 is rotatably connected in the third limiting ring groove 13.

[0030] An actuator is provided on one side of the third transmission component 6. In this embodiment, the output component 61 can be a gear or a shaft, including but not limited to the gear structure shown in the reference figure of this utility model. The specific form needs to be changed according to the actuator.

[0031] Operating principle: During operation, when the first transmission component 2 rotates clockwise, its annular inclined surface 24 contacts the contact block 43, driving the second transmission component 4 to generate axial displacement and causing its teeth 44 to mesh with the teeth 44 of the third transmission component 6, thereby achieving power transmission. When the first transmission component 2 rotates counterclockwise to a specific angle, the second transmission component 4 retracts axially under the action of the reset component 5, disengaging from the third transmission component 6, at which point the third transmission component 6 can rotate freely. Thanks to the symmetrical design of the mechanism, the above-mentioned automatic clutch process can be effectively realized in both the forward and reverse rotation directions.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
