Description
Technical Field
[0001] This utility model belongs to the field of intelligent bed technology, and in particular relates to a bed frame energy-saving drive motor protection device. Background Technology
[0002] A smart bed is a type of electric bed with intelligent functions. It is controlled and intervened by big data and sensors and is a product that has emerged in response to the trend of smart homes.
[0003] When a smart bed's motor starts instantaneously, the force exerted through the motor's driving gear acts directly on the driven gear, resulting in a relatively high instantaneous starting load on the motor. This can cause significant damage to the motor during the instantaneous start-up process, which is common in smart bed motors.
[0004] To address this issue, we propose a bed frame energy-saving drive motor protection device. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the instantaneous start-up of conventional smart bed motors causes significant damage to the motors, and to propose an energy-saving drive motor protection device for bed frames.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A protective device for an energy-saving drive motor of a bed frame includes a first turntable, a spring-loaded transmission frame, and a gear. The spring-loaded transmission frame is located inside the first turntable, and its outer end is fixedly connected to the inner wall of the first turntable. The tail of the gear is fixedly installed inside the spring-loaded transmission frame. The rotor of the energy-saving drive motor drives the first turntable to rotate, which in turn drives the spring-loaded transmission frame to rotate. The spring-loaded transmission frame buffers the torque before applying it to the gear, causing the gear to drive the gear of the energy-saving drive motor to rotate. This reduces the instantaneous load on the energy-saving drive motor during startup and facilitates the protection of the motor.
[0008] Preferably, the first turntable includes a second turntable, with a transmission ring fixedly connected to the front of the second turntable, and the outer end of the elastic transmission frame fixedly connected to the inner wall of the transmission ring. The rotor of the bed frame energy-saving drive motor drives the second turntable to rotate, and the second turntable applies torque to the elastic transmission frame, facilitating transmission from the first turntable to the elastic transmission frame.
[0009] Preferably, the first turntable further includes a retaining ring, one end of which is fixedly connected to the outside of the second turntable. The retaining ring increases the mounting range between the first turntable and the rotor of the energy-saving drive motor of the bed frame, thereby improving the stability between them.
[0010] Preferably, the first turntable further includes blades, which are evenly distributed outside the transmission ring, and the roots of the blades are fixedly connected to the transmission ring. When the bed frame energy-saving drive motor drives the second turntable to rotate, the second turntable drives the transmission ring to rotate, which in turn drives the blades to revolve. The blades blow out airflow, which accelerates the heat dissipation of the bed frame energy-saving drive motor and prevents the bed frame energy-saving drive motor from overheating.
[0011] Preferably, the elastic transmission frame includes a spiral spring and a first rotating ring. The first rotating ring is fixedly connected to the tail of the gear. The spiral spring is evenly distributed outside the first rotating ring, with its root fixedly connected to the first rotating ring and its outer end fixedly connected to the inner end of the transmission ring. When the transmission ring drives the spiral spring, the elastic force of the spiral spring acts on the first rotating ring after buffering, causing the first rotating ring to apply the buffered force to the gear, thus facilitating the buffering of the force.
[0012] Preferably, the gear includes a second rotating ring and a gear body. Bearings are installed inside the second rotating ring and the gear body, and the first rotating ring is fixedly connected to the outside of the second rotating ring. The second rotating ring and the gear body are rotatably mounted on the rotor of the energy-saving drive motor on the bed frame via the bearings. When the helical spring clip dampens the force and causes the first rotating ring to rotate, the first rotating ring drives the second rotating ring to rotate, so that the second rotating ring uses the dampened force to drive the gear body to act on the target gear, thus facilitating the protection of both the gear body and the target gear.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. The rotor of the bed frame energy-saving drive motor drives the first turntable to rotate, which in turn drives the elastic transmission frame to rotate. The elastic transmission frame buffers the torque and then applies it to the gears, causing the gears to drive the gears of the bed frame energy-saving drive motor to rotate. This reduces the instantaneous load on the bed frame energy-saving drive motor during startup and facilitates the protection of the bed frame energy-saving drive motor.
[0015] 2. The rotor of the energy-saving drive motor of the bed frame drives the second turntable to rotate, and the second turntable applies torque to the elastic transmission frame, which facilitates the transmission of the first turntable to the elastic transmission frame.
[0016] 3. By using a fixing ring, the installation and fixing range between the first turntable and the energy-saving drive motor rotor of the bed frame is increased, thereby improving the firmness between the first turntable and the energy-saving drive motor rotor of the bed frame.
[0017] 4. When the bed frame energy-saving drive motor drives the second turntable to rotate, the second turntable drives the transmission ring to rotate, and the transmission ring drives the blades to revolve. The blades blow out airflow, which accelerates the heat dissipation of the bed frame energy-saving drive motor and prevents the bed frame energy-saving drive motor from overheating.
[0018] 5. When the transmission ring drives the spiral spring, the spring force of the spiral spring acts on the first rotating ring after being buffered, so that the first rotating ring applies the buffered force to the gear, which facilitates the buffering of the force.
[0019] 6. The second rotating ring and the gear body are rotatably mounted on the energy-saving drive motor rotor of the bed frame through bearings. When the spiral spring bar causes the first rotating ring to rotate after buffering the force, the first rotating ring drives the second rotating ring to rotate, so that the second rotating ring drives the gear body to act on the target gear after buffering the force, which facilitates the protection of the gear body and the target gear.

[0025] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0026] like Figure 1 As shown, a protective device for an energy-saving drive motor of a bed frame includes a first turntable 2, a spring transmission frame 3, and a gear 4. The spring transmission frame 3 is located inside the first turntable 2, and its outer end is fixedly connected to the inner wall of the first turntable 2. The tail of the gear 4 is fixedly installed inside the spring transmission frame 3. The first turntable 2 is fixedly installed on the rotor of the energy-saving drive motor of the bed frame, and the gear 4 is rotatably installed on the rotor of the energy-saving drive motor of the bed frame, so that the gear 4 meshes with the gear of the energy-saving drive motor of the bed frame.
[0027] like Figure 1 and 2As shown, the first turntable 2 includes a second turntable 21. A transmission ring 23 is fixedly connected to the front of the second turntable 21, and the outer end of the elastic transmission frame 3 is fixedly connected to the inner wall of the transmission ring 23. The rotor of the bed frame energy-saving drive motor drives the second turntable 21 to rotate, and the torsional force is applied to the elastic transmission frame 3 through the second turntable 21.
[0028] like Figure 1 and 2 As shown, the first turntable 2 also includes a retaining ring 24, one end of which is fixedly connected to the outside of the second turntable 21. The retaining ring 24 increases the mounting and fixing range between the first turntable 2 and the rotor of the energy-saving drive motor of the bed frame.
[0029] like Figure 1 and 2 As shown, the first turntable 2 also includes blades 22, which are evenly distributed outside the transmission ring 23, and the roots of the blades 22 are fixedly connected to the transmission ring 23. When the bed frame energy-saving drive motor drives the second turntable 21 to rotate, the second turntable 21 drives the transmission ring 23 to rotate, and the transmission ring 23 drives the blades 22 to revolve. The blades 22 blow out airflow, which accelerates the heat dissipation of the bed frame energy-saving drive motor.
[0030] like Figure 1 and 3 As shown, the elastic transmission frame 3 includes a spiral spring strip 31 and a first rotating ring 32. The first rotating ring 32 is fixedly connected to the tail of the gear 4. The spiral spring strip 31 is evenly distributed outside the first rotating ring 32, and the root of the spiral spring strip 31 is fixedly connected to the first rotating ring 32. The outer end of the spiral spring strip 31 is fixedly connected to the inner end of the transmission ring 23. When the transmission ring 23 drives the spiral spring strip 31, the elastic force of the spiral spring strip 31 buffers the force and acts on the first rotating ring 32, causing the first rotating ring 32 to apply the buffered force to the gear 4.
[0031] like Figure 1 and 4 As shown, gear 4 includes a second rotating ring 41 and a gear body 42. Bearings 43 are installed inside the second rotating ring 41 and gear body 42. A first rotating ring 32 is fixedly connected to the outside of the second rotating ring 41. The second rotating ring 41 and gear body 42 are rotatably mounted on the rotor of the energy-saving drive motor on the bed frame via the bearings 43. When the helical spring 31 dampens the force and causes the first rotating ring 32 to rotate, the first rotating ring 32 drives the second rotating ring 41 to rotate, causing the second rotating ring 41 to apply the dampened force to the gear body 42, which then acts on the target gear.
[0032] Working principle: The rotor of the bed frame energy-saving drive motor drives the first turntable 2 to rotate, which in turn drives the elastic transmission frame 3 to rotate. The elastic transmission frame 3 buffers the torque and then applies it to the gear 4. The gear 4 then drives the gear of the bed frame energy-saving drive motor to rotate with the buffered torque, thereby reducing the instantaneous load on the bed frame energy-saving drive motor when it starts up and protecting the bed frame energy-saving drive motor.
[0033] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.
[0034] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
