Description

Linear actuator with force detection mechanism

This application relates to a linear actuator technology, and more particularly to a linear actuator with a force detection mechanism.

Linear actuators are commonly used in electric beds, nursing beds, hospital beds, electric height-adjustable desks or chairs for adjusting height or tilt. When a user encounters an obstacle during the adjustment process, the user will come into contact with the obstacle and generate an interaction force, which will be transmitted to the linear actuator. If the linear actuator does not stop operating immediately, it will be damaged by the obstacle; if the obstacle is a human body, it will cause injury to the person.

Furthermore, most existing linear actuators do not have dynamic detection capabilities. When they are used on medical bed frames, medical staff or patients' families cannot know whether the patient is in bed or out of bed through terminal devices or equipment.

Therefore, how to solve the problems of product damage due to impact, human injury, and whether the patient is in bed or out of bed is the technical problem that this applicant wants to solve.

One objective of this application is to provide a linear actuation device with a force detection mechanism that can reduce product damage from impacts and can always know whether a patient is in bed or out of bed.

To achieve the above objectives, this application provides a linear actuation device with a force detection mechanism, comprising a housing, a transmission mechanism, an elastic body, and a Hall effect sensor. The housing includes a fixed component; the transmission mechanism is connected to the housing and includes a force-receiving component; the elastic body is disposed between the fixed component and the force-receiving component; the Hall effect sensor is disposed between the fixed component and the force-receiving component; wherein, when the force on the transmission mechanism changes, the force-receiving component and the fixed component will generate a relative displacement, and the Hall effect sensor will generate an output signal through the displacement.

This application also has the following function: when the load changes during the extension or retraction of the telescopic tube, the internal elastic body will undergo slight deformation, which will change the distance between the first and second sensors and generate an output signal. This output signal will be transmitted to the control box or control terminal, so that medical personnel can detect whether the patient is in bed or out of bed (i.e., detection of bed frame dynamics). In addition, it can also be used as a collision avoidance warning. If the telescopic tube encounters an obstacle during its extension or retraction, preventing it from extending or retracting smoothly, or if it is impacted, the force on the guide screw will change, causing the elastic body to deform. The Hall effect sensor detects the deformation of the elastic body and transmits the result to the control box, which then cuts off power to the electric actuator, thus improving safety. This application has a simple structure, is easy to assemble, and has relatively low material costs.

The detailed description and technical content of this application are illustrated below with accompanying drawings. However, the accompanying drawings are for reference and illustration purposes only and are not intended to limit this application.

Please refer to Figures 1 to 6, which are exploded views of the first embodiment of this application, schematic diagrams of partial component combinations, exploded views of partial components, cross-sectional views of partial component combinations, enlarged view of Figure 4, and cross-sectional view of the usage state.

The linear actuator of this embodiment is an electric push rod, which mainly includes a housing 10, a transmission mechanism 20, an elastic body 30 and a Hall sensor component 40.

The housing 10 of this embodiment mainly includes a fixing component 11 and a fastener 12. The fixing component 11 of this embodiment is a rear support of an electric push rod, which has a boss 111 and an outer ring 112 formed around the boss 111. A recess 113 is provided at the center of the boss 111, an inner ring 114 is provided on the end face of the boss 111, and a groove 115 is provided on the inner wall of the outer ring 112.

The transmission mechanism 20 is connected to the housing 10. The transmission mechanism 20 of this embodiment mainly includes a force-bearing component 21. The force-bearing component 21 of this embodiment mainly includes a mechanism 211, a bearing 212, a telescopic tube 213, a locking fastener 214 and a fixed wheel 215. One end of the mechanism 211 is connected to the bearing 212. One end of the telescopic tube 213 is connected to a nut 2131. The telescopic tube 213 is screwed to the mechanism 211 through its nut 2131 and transmits power. The locking fastener 214 locks the mechanism 211 and tightens the bearing 212. The bearing 212 is housed within the aforementioned outer ring 112 and is stopped by the buckle 12 embedded in the groove 115. The fixed wheel 215 is sleeved on the aforementioned movement 211 and abuts against the end face of the bearing 212.

The transmission mechanism 20 of this embodiment also includes a worm gear 22, a guide member 23 and a clutch wheel 24. The guide member 23 is sleeved on the movement 211, the worm gear 22 is sleeved on the guide member 23, and the clutch wheel 24 is sleeved between the guide member 23 and the fixed wheel 215, and can move axially along the guide member 23 to engage or disengage with the fixed wheel 215.

The elastic body 30 in this embodiment is a slanted disc-shaped spring plate disposed between the fixed member 11 and the force-receiving member 21. This elastic body 30 has a central hole 31 and an inclined plate 32 formed around the outer periphery of the central hole 31. The central hole 31 is fitted onto the aforementioned inner ring 114, and the area of the inclined plate 32 away from the central hole 31 abuts against the end face of the bearing 212.

The Hall effect sensor assembly 40 mainly includes a first sensor 41 and a second sensor 42 corresponding to the first sensor 41. The first sensor 41 is disposed in the recess 113 of the fixing component 11, and the second sensor 42 is disposed on the end face of the mechanism 211 of the force-receiving component 21. The first sensor 41 can be a Hall effect sensor or a magnetic material; the second sensor 42 can also be a Hall effect sensor or a magnetic material. In this embodiment, the first sensor 41 is a magnetic material, and the second sensor 42 is a Hall effect sensor. The magnetic material can be a magnet.

The linear actuation device of this embodiment also includes a drive mechanism 50, which is connected to the aforementioned transmission mechanism 20 and housing 10, for driving the worm gear 22 and the movement 211 of the transmission mechanism 20 to produce corresponding actuation. Since the drive mechanism 50 is prior art, it will not be described again.

During operation, when the telescopic tube 213 of the transmission mechanism 20 is subjected to an axial force, the elastic body 30 will deform, causing a change in the distance between the force-bearing component 21 and the fixed component 11. Simultaneously, the distance between the first sensor 41 and the second sensor 42 changes accordingly, and this signal is output electronically. The axial force can be a tension or a thrust applied to the telescopic tube 213.

To further explain, when the electric push rod is subjected to an external load, the load is transmitted from the telescopic tube 213 to the nut 2131. The load is then transmitted to the mechanism 211 through the screw connection between the nut 2131 and the mechanism 211. The load is then transmitted from the mechanism 211 to the fixed wheel 215 through the mechanical connection between the fixed wheel 215 and the mechanism 211. After that, the load is transmitted to the bearing 212 and then from the bearing 212 to the elastic body 30. Since the second sensor 42 is fixed to the end face of the mechanism 211 and the locking fastener 214, and the first sensor 41 is disposed in the recess 113 of the fixed component 11, the elastic body 30 will deform under the load, causing the distance between the mechanism 211 of the force-bearing component 21 and the boss 111 of the fixed component 11 to change. At the same time, the distance between the second sensor 42 and the first sensor 41 changes. When the distance between the second sensor 42 and the first sensor 41 is greater, the received Gaussian value is weaker; conversely, when the distance between the second sensor 42 and the first sensor 41 is smaller, the received Gaussian value is stronger. This displacement signal is output to a controller or a control terminal to cut off the power or make the motor rotate in the opposite direction, thereby enabling the electric push rod to play a protective role.

When the telescopic tube 213 of the transmission mechanism 20 is subjected to axial force, the bearing 212 pushes the sleeve 216, and the elastic body 30 is deformed through the sleeve 216, thereby changing the distance between the mechanism 211 of the force-bearing component 21A and the boss 111 of the fixed component 11.
