Description

Technical Field

[0001] This utility model relates to the field of hinges, and in particular to a hinge with a clutch function. Background Technology

[0002] Hinges are core components in mechanical structures used to connect two parts and enable relative rotation, and are widely used in home decoration, industrial equipment, medical fields and other fields. Traditional hinges typically consist of a rotating body, a pivot, and fixed components. The pivot transmits torque or friction to maintain the rotational stability and angle adjustment function of the structure.

[0003] However, with the diversification of application scenarios, users' functional requirements for hinges are becoming increasingly complex. In some scenarios, the hinge needs to provide a fixed torque to maintain structural stability, while in others, the hinge needs to completely disengage the torque to achieve free rotation or resistance-free adjustment, such as in multi-directional probes of medical equipment. Traditional hinges have a single function, typically only able to achieve unidirectional rotation through fixed friction or torque, and cannot dynamically separate or combine power transmission during operation, resulting in insufficient compatibility in multi-scenario applications. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a hinge with a clutch function, which can effectively solve the technical problem of single function.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A hinge with a clutch function includes a rotating body and a rotating shaft assembly. The rotating shaft assembly is installed in the rotating body. The rotating body and the rotating shaft assembly are used to connect two parts that need to rotate. The rotating shaft assembly includes a brake disc, a shaft core, a gear disc, and a fixing nut. The fixing nut is threaded to one end of the shaft core. The shaft core is connected to the rotating body through the fixing nut. A connecting pin is provided at the end of the shaft core away from the fixing nut. The gear disc is installed in the middle section of the connecting pin. The surface of the brake disc is provided with a positioning hole. The end of the connecting pin away from the shaft core is paired and inserted into the positioning hole. The brake disc and the connecting pin are slidably connected. The end of the gear disc near the brake disc is provided with a number of tooth grooves. The tooth grooves are evenly distributed around the shaft core of the gear disc. The end of the brake disc near the gear disc is provided with transmission teeth for meshing with the tooth grooves. An elastic element is provided between the brake disc and the gear disc. An elastic separation element is used to separate the brake disc from the gear disc. When the brake disc and the gear disc are engaged, the torque of the brake disc is transmitted sequentially to the gear disc, the connecting pin, the shaft core, and the rotating body.

[0007] Furthermore, the surface of the shaft core is provided with a positioning boss, the inner wall of the rotating body is provided with a pressure ring, the fixing nut and the positioning boss cooperate to clamp the two ends of the pressure ring, and a washer is provided between the fixing nut, the positioning boss and the pressure ring.

[0008] Furthermore, two or more compression springs are provided between the gasket and the fixing nut, and the two or more compression springs are arranged alternately.

[0009] Furthermore, the surface of the rotating body is provided with a fixing seat for assembling with the product, and the rotating body can rotate relative to the fixing seat within the fixing seat.

[0010] Furthermore, the inner wall of the fixed base is connected to the surface of the rotating body through a rotating bearing. The surface of the rotating body is provided with a limiting step and a handle sleeve, which are located at both ends of the fixed base.

[0011] Furthermore, the rotating body is provided with a detachable fixing cover at one end near the handle sleeve. The bottom surface of the fixing cover presses against the inner wall of the handle sleeve. The inner wall of the handle sleeve is provided with a positioning block. The surface of the rotating body is provided with a positioning groove. The positioning blocks are paired and inserted into the groove so that torque can be transmitted between the handle sleeve and the rotating body.

[0012] Furthermore, the surface of the rotating body is provided with an external gear, which is used to increase the number of parts that the rotating body can transmit power.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: By engaging or disengaging the brake disc and the gear disc, power transmission or disconnection between the rotating body and the shaft assembly can be quickly achieved. When shaft torque is required to participate in structural rotation, the brake disc engages with the gear disc, and the torque is transmitted to the rotating body through the transmission teeth and grooves, enabling the hinge to perform transmission functions. When free rotation or resistance-free adjustment is required, the elastic element pushes the brake disc to separate from the gear disc, allowing the rotating body to rotate freely without being affected by shaft torque, thus disconnecting torque transmission. This allows the hinge to flexibly switch working modes according to actual needs, meeting diverse application scenarios, and the flexible switching function significantly improves the hinge's applicability and practicality.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is combined Figures 1-5 A detailed description of a hinge with a clutch function according to this utility model is provided:

[0022] A hinge with a clutch function includes a rotating body 1 and a rotating shaft assembly 2. The rotating shaft assembly 2 is installed inside the rotating body 1. The rotating body 1 and the rotating shaft assembly 2 are used to connect two parts that need to rotate. The rotating shaft assembly 2 includes a brake disc 3, a shaft core 4, a gear disc 5, and a fixing nut 6. The fixing nut 6 is threaded to one end of the shaft core 4. The shaft core 4 is connected to the rotating body 1 through the fixing nut 6. A connecting pin 7 is provided at the end of the shaft core 4 away from the fixing nut 6. The gear disc 5 is installed in the middle section of the connecting pin 7. The brake disc 3... The surface is provided with positioning holes 301. The end of the connecting pin 7 away from the shaft core 4 is paired and inserted into the positioning holes 301. The brake disc 3 is slidably connected to the connecting pin 7. The gear disc 5 is provided with a number of tooth grooves 501 at the end near the brake disc 3. The tooth grooves 501 are evenly distributed around the shaft core 4 of the gear disc 5. The end of the brake disc 3 near the gear disc 5 is provided with transmission teeth 302 for meshing with the tooth grooves 501. A spring 8 is provided between the brake disc 3 and the gear disc 5. In its natural state, the spring 8 keeps the brake disc 3 and the gear disc 5 in a separated state. When it is necessary to engage, only an external force needs to be applied to make the brake disc 3 overcome the elastic force of the spring 8 and engage with the gear disc 5; when the external force is removed, the spring 8 automatically pushes the brake disc 3 to separate from the gear disc 5. This design simplifies clutch operation, requiring no additional tools or complicated steps, and significantly improves the ease of use of the hinge. When the brake disc 3 and the gear disc 5 are engaged, the transmission gear 302 and the tooth groove 501 mesh tightly, ensuring that the torque is stably transmitted from the brake disc 3 to the gear disc 5, the connecting pin 7, the shaft core 4 and the rotating body 1, avoiding slippage or torque loss, and ensuring the reliability and durability of the hinge in the engaged state.

[0023] By engaging or disengaging the brake disc 3 and the gear disc 5, power transmission or disconnection between the rotating body 1 and the shaft assembly 2 can be quickly achieved. When shaft torque is required to participate in structural rotation, the brake disc 3 engages with the gear disc 5, and the torque is transmitted to the rotating body 1 through the transmission teeth 302 and the tooth grooves 501, enabling the hinge to have a transmission function. When free rotation or resistance-free adjustment is required, the spring 8 pushes the brake disc 3 to disengage from the gear disc 5, allowing the rotating body 1 to rotate freely without being affected by shaft torque, thus disconnecting the torque transmission. This allows the hinge to flexibly switch working modes according to actual needs, meeting diverse application scenarios. The flexible switching function significantly improves the hinge's applicability and practicality. The shaft assembly 2 adopts a modular design, and the shaft core 4, brake disc 3, gear disc 5, and spring 8 can all be independently disassembled and replaced. When a component is damaged, only the corresponding component needs to be replaced without replacing the entire hinge, reducing maintenance costs and time, while extending the hinge's service life.

[0024] The surface of the rotating body 1 is provided with a fixed seat 11 for assembly with the product. The rotating body 1 can rotate relative to the fixed seat 11 within the fixed seat 11. The fixed seat 11 is fixedly connected to the product by bolts 14. The inner wall of the fixed seat 11 is connected to the surface of the rotating body 1 through a rotating bearing. The surface of the rotating body 1 is provided with a limiting step 102 and a handle sleeve 12. The limiting step 102 and the handle sleeve 12 are located at both ends of the fixed seat 11, respectively. The end of the rotating body 1 near the handle sleeve 12 is provided with a detachable fixing cover 13. The bottom surface of the fixing cover 13 presses against the inner wall of the handle sleeve 12. The inner wall of the handle sleeve 12 is provided with a positioning block 1201. The surface of the rotating body 1 is provided with a positioning groove 104. The positioning blocks 1201 are inserted into the groove to allow torque to be transmitted between the handle sleeve 12 and the rotating body 1.

[0025] The surface of the shaft core 4 is provided with a positioning boss 401, and the inner wall of the rotating body 1 is provided with a pressure ring part 101. The fixing nut 6 and the positioning boss 401 cooperate to clamp the two ends of the pressure ring part 101. A washer 9 is provided between the fixing nut 6, the positioning boss 401 and the pressure ring part 101. The pressure ring part 101 is pressed by the washer 9, thereby realizing the torque transmission between the rotating body 1 and the shaft core 4. Through the uniform pressing action of the washer 9, the torque transmission between the shaft core 4 and the rotating body 1 is more stable, avoiding torque loss or structural shaking caused by local loosening, and further improving the reliability and durability of the hinge.

[0026] Four compression springs 10 are provided between the gasket 9 and the fixing nut 6. The compression springs 10 are arc-shaped and arranged in an alternating pattern with two or more compression springs 10. Through the elastic deformation of the springs, the clamping force is distributed more evenly, and the springs can absorb vibration and impact during operation, reduce wear between the shaft core 4 and the rotating body 1, and extend the service life of the hinge. The pressure of the gasket 9 on the pressure ring 101 can also be adjusted by increasing or decreasing the number of compression springs 10. An external gear 103 is provided on the surface of the rotating body 1. The external gear 103 is used to increase the number of parts that the rotating body 1 can transmit, expand the functionality of the hinge, and enable it to adapt to more complex transmission requirements, such as realizing multi-stage transmission or synchronous rotation in industrial equipment.
