[0048] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0049] Figures 1-3 A structural diagram of an electrically operated lifting examination bed according to an embodiment of this application is shown. Figures 1-3 As shown, the examination bed may include:

[0050] Base frame 2;

[0051] Bed frame 4, which is located above base frame 2;

[0052] The first adjustment component is mounted on the base frame 2. The first adjustment component drives the bed frame 4, thereby changing the height of the bed frame 4 relative to the base frame 2.

[0053] Back support 9, which is mounted on bed frame 4;

[0054] The back support 9 has a first state and a second state. When the back support 9 is in the first state, the back support 9 is horizontally positioned with the bed frame 4.

[0055] When the back support 9 is in the second state, there is an angle between the back support 9 and the bed frame 4;

[0056] The second adjustment component is mounted on the bed frame 4 and drives the back support 9 to switch between the first state and the second state.

[0057] In this embodiment, the bed frame 4 is in the lowest position in the initial state, at which time the distance between the bed frame 4 and the base frame 2 is the smallest, and the height of the bed frame 4 is 550mm. In use, the bed frame 4 is raised by activating the first adjustment component, and the distance between the bed frame 4 and the base frame 2 gradually increases. The height range of the bed frame 4 is 550mm to 750mm.

[0058] When the patient needs to get up, the angle of the back support 9 relative to the bed frame 4 is adjusted by the second adjustment component. The adjustment range of the back support 9 is 0° to 66° (that is, the angle formed between the back support 9 and the bed frame 4 is 180° to 114°).

[0059] The height of the bed frame 4 can be adjusted according to the actual use of different patients by setting the first adjustment component. The angle of the back support 9 relative to the bed frame 4 can be adjusted according to the needs of different patients when lying down, thereby increasing the comfort when lying down. The setting of the first and second adjustment components is more labor-saving than the traditional manual adjustment method.

[0060] It should be noted that the first state of the back support 9 is the non-use state, at which time the back support 9 and the bed frame 4 form a 180° angle;

[0061] The second state is the support state (use state), in which the back support 9 and the bed frame 4 form an angle.

[0062] like Figures 1-3 As shown, in one embodiment,

[0063] The first adjustment component includes:

[0064] The first fixing rod 15 is mounted on the base frame 2;

[0065] The second fixing rod 16 is installed on the bed frame 4;

[0066] Rotating arm 3, one end of rotating arm 3 is set on the first fixed rod 15, and the end of the second fixed rod 16 away from the bed frame 4 is set on rotating arm 3;

[0067] Link 13 is located on the end of the rotating arm 3 away from the first fixed rod 15;

[0068] The overall lifting assembly 5 is mounted on the bed frame 4, and the drive end of the overall lifting assembly 5 is located on the connecting rod 13.

[0069] In this embodiment, when the overall lifting assembly 5 is activated, the overall lifting assembly 5 pushes the connecting rod 13 to move. At this time, the rotating arm 3 rotates relative to the first fixed rod 15, and at the same time, the rotating arm 3 rotates relative to the connecting rod 13 and the second fixed rod 16 to adjust the height of the bed frame 4.

[0070] Specifically, there are four of each of the first fixing rod 15, the second fixing rod 16 and the rotating arm 3, which are respectively set at the four corners of the bed frame 4 and the base frame 2. A connecting rod (not shown in the figure) is provided on the rotating arm 3 on the same side. The drive end of the overall lifting assembly 5 is located on the connecting rod near the back support 9.

[0071] There are two connecting rods 13, located on both sides of the overall lifting assembly 5. The two ends of the two connecting rods 13 are respectively located on the connecting rods on the corresponding sides.

[0072] Specifically, the overall lifting component 5 is an overall lifting motor, or it can be set as an electric push rod.

[0073] like Figure 1 and Figure 3 As shown, in one embodiment,

[0074] The rotating arm 3 has a V-shaped cross-section and has a first end 31, a second end 32 and a third end 33. The first fixing rod 15 and the connecting rod 13 are located at the first end 31 and the second end 32 respectively, and the second fixing rod 16 is located on the third end 33 of the rotating arm 3.

[0075] In this embodiment, the first fixing rod 15 corresponds to the first end 31, the connecting rod corresponds to the second end 32, the second height rod corresponds to the third end 33, and the third end 33 is located at the top of the rotating arm 3, which facilitates the overall height adjustment of the bed frame 4 through the overall lifting assembly 5.

[0076] In one implementation, it further includes:

[0077] The first mounting bracket 17 is mounted on the bed frame 4, and the end of the overall lifting assembly 5 away from the connecting rod 13 is mounted on the first mounting bracket 17.

[0078] In this embodiment, the installation of the overall lifting assembly 5 is facilitated by the first mounting bracket 17.

[0080] The second adjustment component includes:

[0081] The backrest lifting assembly 6 is mounted on the bed frame 4, and its output end is mounted on the backrest support 9. The backrest lifting assembly 6 is located on one side of the connecting rod 13.

[0082] In this embodiment, the back support 9 is adjusted relative to the bed frame 4 by means of the back lifting component 6. The back lifting component 6 is located on one side of the connecting rod 13 to avoid collision between the back lifting component 6 and the connecting rod 13 when in use. The adjustment of the back support 9 can be carried out at the same time as the height adjustment of the bed frame 4 (that is, the back lifting component 6 and the overall lifting component 5 can operate at the same time).

[0083] Specifically, it also includes a second mounting bracket 18, which is mounted on the bed frame 4. The end of the backrest lifting assembly 6 away from the backrest support 9 is mounted on the second mounting bracket 18 to facilitate the installation of the backrest lifting assembly 6.

[0086] The toilet paper holder 7 is mounted on the back support 9.

[0087] Pillow 8 is placed on the back mattress 12;

[0088] Mattress 12 is mounted on bed frame 4.

[0089] In this embodiment, the mattress 12 and the back mattress 12 are respectively set on the bed frame 4 and the back support 9. The mattress 12 and the back mattress 12 are set separately to facilitate the adjustment of the back support 9 and the bed frame 4. A disposable sheet is wrapped on the toilet paper holder 7. When the patient is not lying on the mattress 12, the disposable sheet is pulled straight at the foot of the bed to facilitate the placement and laying of the disposable sheet.

[0090] The placement of pillow 8 increases comfort when lying down.

[0092] 1. The swivel caster is mounted on the base frame 2.

[0093] Push handle 14 is installed on bed frame 4.

[0094] In this embodiment, when the base frame 2 needs to be moved, simply release the brake of the swivel caster 1 and push it by grasping the push handle 14; when it does not need to be moved, the brake of the swivel caster 1 needs to be locked.

[0095] The swivel caster 1 is a commercially available four-inch swivel caster with brake pads. Since this caster is a common type of caster on the market, it will not be described in detail here.

[0096] like Figure 1 and Figure 3 As shown, in one embodiment, it further includes:

[0097] Controller 10 is mounted on bed frame 4;

[0098] The hand controller 11 is mounted on the bed frame 4.

[0099] In this embodiment, both the overall lifting assembly 5 and the back lifting assembly 6 can be adjusted by the controller 10 and the hand controller 11. The hand controller 11 and the controller 10 are common motor controllers or electric push rod controllers on the market. The hand controller 11 and the controller 10 control the start and stop of the overall lifting assembly 5 and the back lifting assembly 6.
