Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor for adjusting the support angle of a hospital bed. Background Technology

[0002] As the core device for converting electrical energy into mechanical energy, electric motors are widely used in industrial automation, home appliances, and medical equipment. In the field of medical beds, electric push rods are usually used as the driving components for adjusting the bed board angle in order to realize functions such as patient positioning, nursing operations, and comfort optimization.

[0003] The attached diagram of the instruction manual Figure 9 The diagram shows the structure of an electric actuator for adjusting the angle of a hospital bed in the prior art. The electric actuator mainly consists of a cylinder, a piston rod, a screw, and a drive motor. The piston rod moves through one end of the cylinder and forms a transmission pair with the screw threaded inside the cylinder. The motor is fixed on the outside of the cylinder, away from the piston rod, and drives the screw to rotate to achieve the linear extension and retraction of the piston rod, thereby driving the bed board to rise or tilt.

[0004] However, this electric actuator still has the following drawbacks in actual use:

[0005] Low space utilization; the motor is externally mounted on the side wall of the cylinder, which increases the overall radial dimension of the electric actuator. This can easily cause interference in the narrow installation space of the hospital bed, especially for hospital beds with multiple degrees of freedom adjustment, and may limit the layout of other functional modules.

[0006] Therefore, this application proposes a bed support angle adjustment motor. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a bed support angle adjustment motor, which solves the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A bed support angle adjustment motor includes a base plate for mounting on the bed, a motor body fixedly mounted on one side of the base plate, the motor body including a motor housing fixedly connected to the base plate, and an output shaft provided on one side of the motor housing; the bed includes a bed frame, with support legs fixedly mounted in a rectangular array at the bottom of the bed frame, a bed board one fixedly mounted on the top of the bed frame, a bed board two hinged to one side of the bed board one, a gap between the bottom of the bed board one and the bed frame, a slider slidably mounted on one side of the inner wall of the bed frame below the bed board one along the direction of the bed board two, a transmission rod hinged to one side of the slider and hinged to the bottom of the bed board two, and a threaded rod rotatably mounted on one side of the inner wall of the bed frame and threadedly connected to the slider;

[0010] A clamping mechanism is installed on the base plate, which can clamp the base plate onto the bed frame. The output shaft is connected to the threaded rod via a coupling. A fixed plate is fixedly installed on the base plate and movably sleeved outside the output shaft. A sleeve is inserted on the side of the fixed plate near the motor housing and movably sleeved outside the motor housing. The sleeve can fit against both the base plate and the fixed plate.

[0011] Sound-absorbing cotton is fixedly installed on the side of the fixing plate near the housing and on the inner wall of the housing. A snap-fit ​​component that can be connected to the housing is installed on the fixing plate. When the housing is fitted outside the motor housing and the housing is in close contact with the bottom plate and the fixing plate, the snap-fit ​​component can be used to position the housing and the fixing plate.

[0012] Furthermore: the snap-fit ​​component includes snap-fit ​​rods that are hinged in a rectangular array to the side of the fixing plate near the motor housing. Positioning plates are integrally formed on both sides of the housing. Snap-fit ​​holes are symmetrically opened on the two positioning plates. The four snap-fit ​​rods can pass through the four snap-fit ​​holes respectively and snap-fit ​​with the positioning plates.

[0013] Furthermore: the clamping mechanism includes clamping plates and bidirectional threaded rods. Two clamping plates are slidably mounted vertically on the side of the base plate away from the motor housing. A vertical bidirectional threaded rod is rotatably mounted on the base plate, and the bidirectional threaded rod is threadedly connected to both clamping plates.

[0014] Furthermore, multiple rubber pads are installed in a horizontal linear array on the side of the base plate away from the motor housing and between the opposite sides of the two clamping plates.

[0015] Furthermore: the clamping plate includes a connecting plate that is slidably connected to the base plate, and the ends of the two connecting plates away from the base plate are integrally formed with inclined abutment plates, and the ends of the two abutment plates away from the connecting plates are close to each other.

[0016] Furthermore: a T-slot is provided on the base plate on the side of the motor housing away from the fixed plate, and a T-block is fixedly installed on the housing. When the housing is fitted outside the motor housing and the housing is in close contact with both the base plate and the fixed plate, the T-block is inserted into the T-slot and engaged with the base plate.

[0017] Furthermore: multiple heat-conducting plates 1, each penetrating the sound-absorbing cotton, are fixedly installed on the inner wall of the sleeve on the side away from the fixing plate. Heat-conducting plates 2 are fixedly connected to the ends of the multiple heat-conducting plates 1. When the sleeve is fitted outside the motor housing and the sleeve is in contact with both the bottom plate and the fixing plate, the heat-conducting plates 2 are in contact with the motor housing.

[0018] This invention provides a motor for adjusting the support angle of a hospital bed. Compared with the prior art, it has the following advantages:

[0019] 1. When installing this motor, place the base plate on one side of the threaded rod and connect the output shaft to the threaded rod through the coupling. At this time, the base plate can be fixedly installed on the bed frame through the clamping mechanism to complete the installation of this motor. This realizes the axial installation between the motor body and the threaded rod, thereby reducing space occupation and effectively avoiding the impact on the layout of other functions.

[0020] 2. The design of the fixing plate and the housing achieves the effect of encapsulating the motor body, effectively preventing the motor body from being directly exposed to the ambient air. Since sound-absorbing cotton is fixedly installed on the side of the fixing plate near the housing and on the inner wall of the housing, the vibration and noise generated by the motor body when it is working will be dispersed into the housing. At this time, the sound-absorbing cotton absorbs the vibration and noise generated by the motor body when it is working, thereby effectively suppressing the transmission of noise into the ward. This effectively prevents the vibration and noise generated by the motor body when it is working from affecting the rest of other patients in the ward, which is conducive to the patient's recovery.

[0021] 3. Through the design of the rubber pads, when installing this motor and positioning it between the base plate and the bed frame, multiple rubber pads are made to abut against the base plate and the bed frame. When the motor body works and the output shaft rotates, causing the second bed plate to rotate on one side of the first bed plate, some of the vibration force generated by the motor body is transmitted to the base plate. At this time, the rubber pads absorb the vibration force transmitted to the base plate, thereby effectively reducing the vibration force generated by the motor body when it works from being transmitted to the bed frame, causing the bed frame to resonate and cause noise.

[0022] 4. Through the design of T-blocks and T-slots, when the housing is fitted outside the motor housing and fits snugly against the base plate and the fixing plate, the T-blocks are inserted into the T-slots and engage with the base plate, further improving the positioning effect of the housing.

[0035] Example 1

[0036] To address the technical problems in the background section, the following is provided: a bed support angle adjustment motor.

[0037] Combination Figures 1-8As shown, the present invention provides a bed support angle adjustment motor, including a base plate 1 for mounting on a bed 3, a motor body 11 fixedly mounted on one side of the base plate 1, the motor body 11 including a motor housing 111 fixedly connected to the base plate 1, and an output shaft 112 provided on one side of the motor housing 111; the bed 3 includes a bed frame 31, the bottom of the bed frame 31 is fixedly mounted with support legs 37 in a rectangular array, the top of the bed frame 31 is fixedly mounted with a bed board 32, a bed board 33 is hinged to one side of the bed board 32, there is a gap between the bottom of the bed board 32 and the bed frame 31, a slider 34 is slidably mounted on one side of the inner wall of the bed frame 31 and below the bed board 32 along the direction of the bed board 33, a transmission rod 35 is hinged to one side of the slider 34 and hinged to the bottom of the bed board 33, and a threaded rod 36 threadedly connected to the slider 34 is rotatably mounted on one side of the inner wall of the bed frame 31;

[0038] A clamping mechanism 2 is installed on the base plate 1. The base plate 1 can be clamped on the bed frame 31 by the clamping mechanism 2. The output shaft 112 is connected to the threaded rod 36 through the coupling 113. A fixing plate 4 is fixedly installed on the base plate 1 and is movably sleeved on the outside of the output shaft 112. A sleeve 5 is inserted on the side of the fixing plate 4 near the motor housing 111 and is movably sleeved on the outside of the motor housing 111. The sleeve 5 can fit in close contact with both the base plate 1 and the fixing plate 4.

[0039] The fixing plate 4 is fixedly installed with sound-absorbing cotton 6 on the side near the housing 5 and on the inner side wall of the housing 5. The sound-absorbing cotton 6 is made of polyester fiber cotton. The fixing plate 4 is equipped with a snap-fit ​​piece 7 that can be connected to the housing 5. When the housing 5 is fitted outside the motor housing 111 and the housing 5 is in close contact with the bottom plate 1 and the fixing plate 4, the snap-fit ​​piece 7 can be used to position the housing 5 and the fixing plate 4.

[0040] When installing this motor, the base plate 1 is placed on one side of the threaded rod 36, and the output shaft 112 is connected to the threaded rod 36 through the coupling 113. At this time, the base plate 1 can be fixedly installed on the bed frame 31 through the clamping mechanism 2, thus completing the installation of this motor and realizing the axial installation between the motor body 11 and the threaded rod 36, thereby reducing space occupation and effectively avoiding the impact on other functional layouts. Through the design of the fixing plate 4 and the housing 5, the motor body 11 is encapsulated, effectively preventing the motor body 11 from being directly exposed to the ambient air. Since the fixing plate 4 is fixedly installed on the side near the housing 5 and the inner wall of the housing 5, the vibration and noise generated by the motor body 11 during operation will be dispersed into the housing 5. At this time, the sound-absorbing cotton 6 absorbs the vibration and noise generated by the motor body 11 during operation, thereby effectively suppressing the transmission of noise into the ward, thus effectively preventing the vibration and noise generated by the motor body 11 during operation from affecting the rest of other patients in the ward, which is conducive to the patient's recovery.

[0041] Example 2

[0042] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0043] In this embodiment, the snap-fit ​​component 7 includes snap-fit ​​rods 71 ​​that are hinged in a rectangular array to the side of the fixing plate 4 near the motor housing 111. The two sides of the housing 5 are integrally formed with positioning plates 51. The two positioning plates 51 are symmetrically provided with snap-fit ​​holes 511. The four snap-fit ​​rods 71 ​​can pass through the four snap-fit ​​holes 511 respectively and snap-fit ​​with the positioning plates 51. In use, when positioning the housing 5 and the fixing plate 4, the housing 5 is fitted outside the motor housing 111 so that it fits against the bottom plate 1. Then, a force is applied to the housing 5 to make it move towards the fixing plate 4. During this process, a rotational force is applied to the four snap-fit ​​rods 71 ​​respectively so that the four snap-fit ​​rods 71 ​​can pass through the four snap-fit ​​holes 511 respectively. When the housing 5 and the fixing plate 4 are fitted together, the four snap-fit ​​rods 71 ​​pass through the snap-fit ​​holes 511 on the two positioning plates 51 respectively. At this time, the four snap-fit ​​rods 71 ​​are rotated respectively to snap-fit ​​with the positioning plates 51, thereby positioning the housing 5 and the fixing plate 4.

[0044] In this embodiment, the clamping mechanism 2 includes clamping plates 21 and bidirectional threaded rods 22. Two clamping plates 21 are vertically slidably mounted on the side of the base plate 1 away from the motor housing 111. A vertical bidirectional threaded rod 22 is rotatably mounted on the base plate 1. The bidirectional threaded rod 22 is threadedly connected to both clamping plates 21. In use, when installing the motor, the two clamping plates 21 are positioned above and below the bed frame 31, respectively. When the base plate 1 is in contact with the inner wall of the bed frame 31, the bidirectional threaded rod 22 is rotated to make the two clamping plates 21 slide closer to each other on the base plate 1. This allows the two clamping plates 21 to clamp the bed frame 31, achieving a positioning effect between the base plate 1 and the bed frame 31.

[0045] In this embodiment, multiple rubber pads 8 are installed in a horizontal linear array on the side of the base plate 1 away from the motor housing 111 and between the opposite sides of the two clamping plates 21. Through the design of the rubber pads 8, when the motor is installed and the base plate 1 is positioned with respect to the bed frame 31, the multiple rubber pads 8 are in contact with the base plate 1 and the bed frame 31. When the motor body 11 works and the output shaft 112 rotates, causing the second bed plate 33 to rotate on one side of the first bed plate 32, part of the vibration force generated by the motor body 11 during operation is transmitted to the base plate 1. At this time, the rubber pads 8 absorb the vibration force transmitted to the base plate 1, thereby effectively reducing the situation where the vibration force generated by the motor body 11 during operation is transmitted to the bed frame 31, causing the bed frame 31 to resonate and cause noise.

[0046] Example 3

[0047] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0048] In this embodiment, the clamping plate 21 includes a connecting plate 211 slidably connected to the base plate 1. The ends of the two connecting plates 211 away from the base plate 1 are integrally formed with inclined abutment plates 212, and the ends of the two abutment plates 212 away from the connecting plate 211 are close to each other. By utilizing the design of the clamping plate 21 including the connecting plate 211 and the abutment plates 212, when positioning the base plate 1 and the bed frame 31, after the multiple rubber pads 8 on one side of the base plate 1 abut against the bed frame 31, when the two clamping plates 21 clamp and position the top and bottom of the bed frame 31 respectively, the two abutment plates 212 abut against the bed frame 31. Since the ends of the two abutment plates 212 away from the connecting plate 211 are close to each other, the positioning effect of the base plate 1 is further improved.

[0049] In this embodiment, a T-slot 12 is provided on the base plate 1 on the side of the motor housing 111 away from the fixing plate 4. A T-block 52 is fixedly installed on the sleeve 5. When the sleeve 5 is fitted outside the motor housing 111 and the sleeve 5 is in close contact with both the base plate 1 and the fixing plate 4, the T-block 52 is inserted into the T-slot 12 and engages with the base plate 1. Through the design of the T-block 52 and the T-slot 12, when the sleeve 5 is fitted outside the motor housing 111 and in close contact with both the base plate 1 and the fixing plate 4, the T-block 52 is inserted into the T-slot 12 and engages with the base plate 1, further improving the positioning effect of the sleeve 5.

[0050] In this embodiment, multiple heat-conducting plates 9, each penetrating the sound-absorbing cotton 6, are fixedly installed on the inner wall of the casing 5 on the side away from the fixing plate 4. Heat-conducting plates 91 are fixedly connected to the ends of the multiple heat-conducting plates 9. When the casing 5 is fitted over the motor housing 111 and is in contact with both the base plate 1 and the fixing plate 4, the heat-conducting plates 91 are in contact with the motor housing 111. The heat-conducting plates 9, 91, and 5 are all made of copper plates. During use, when the heat generated by the motor body 11 is dissipated to the motor housing 111, it can be conducted through the heat-conducting plates 91 to the multiple heat-conducting plates 9, thereby transferring the heat generated by the motor body 11 to the casing 5, which is beneficial for dissipating the heat generated by the motor body 11 during operation.
