[0034] Please see Figures 1 to 7 , Figure 1 An examination bed provided in one embodiment of this utility model, such as Figure 1 As shown, it includes:

[0035] Base 2;

[0036] Support unit 4 is mounted on base 2;

[0037] The bed board 1 is mounted on the support unit 4 and can reciprocate horizontally relative to the base 2; the bed board 1 has an internal receiving groove 11 and an opening 14 communicating with the receiving groove 11 on the lower surface of the bed board 1.

[0038] The first roller assembly 3 is mounted on the base 2 via the bracket 6, and the first roller assembly 3 is located in the lower part of the bed plate 1 in the receiving groove 11, sandwiched between the first roller assembly 3 and the support unit 4.

[0039] The drive unit 5 is connected to the bed board 1 via a transmission mechanism and is used to drive the bed board 1 to reciprocate in the horizontal direction.

[0040] A support unit 4 is disposed on the top surface of the base 2. The bed board 1 is mounted on the base 2 via the support unit 4, and the bed board 1 can reciprocate relative to the base 2 along its length. A receiving groove 11 is provided within the bed board 1, and an opening 14 is provided at the bottom of the bed board 1, with the receiving groove 11 communicating with the opening 14. The first end of the bracket 6 is connected to the top surface of the base 2, and the second end of the bracket 6 extends into the receiving groove 11 of the bed board 1 through the opening 14. The shape of the bracket 6 can be any shape that enables this embodiment; for example, the shape of the bracket 6 can be L-shaped, triangular, or similar.

[0041] The first roller assembly 3 includes at least one first roller, which is rotatably mounted on the second end of the bracket 6 about its own axis of rotation, i.e., the first roller assembly 3 is disposed within the receiving groove 11. The outer periphery of the first roller may be covered with rubber or other elastic material, allowing the first roller to elastically contact the bed board 1. The outer periphery of the first roller can contact the inner wall of the receiving groove 11, and the support unit 4 can contact the lower surface of the bed board 1, clamping the lower part of the bed board 1 between the first roller assembly 3 and the support unit 4, ensuring that the bed board 1 can stably reciprocate along the length direction of the bed board 1 on the support unit 4. Specifically, the first roller assembly 3 may include two first rollers arranged side by side along the width direction of the bed board 1, and correspondingly, the number of brackets 6 corresponds to the number of first rollers; or, the first roller assembly 3 may include multiple first rollers arranged along the length direction of the bed board 1, with each first roller spaced apart. The specific number of the first roller assembly 3 can be set according to requirements.

[0042] The drive unit 5 is connected to the transmission mechanism, and the drive unit 5 drives the bed plate 1 to reciprocate along the length of the bed plate 1 through the transmission mechanism.

[0043] In this embodiment, by clamping the lower part of the bed board 1 between the first roller assembly 3 and the support unit 4, the bed board 1 can stably contact the support unit 4, thereby enabling the bed board 1 to stably reciprocate along the length direction of the bed board 1 on the base 2. By placing the first roller assembly 3 within the receiving groove 11, the structure exposed between the bed board 1 and the base 2 is simplified, the volume is reduced, and a bulky structure is avoided; it also reduces the overall volume of the examination bed and lowers the space occupied by the examination bed.

[0044] In some implementations, such as Figure 7 As shown, the support unit 4 includes a matching slide rail 47 and a slide block 46. One of the slide rail 47 and the slide block 46 is fixed to the base 2, and the other of the slide rail 47 and the slide block 46 is connected to the lower surface of the bed board 1.

[0045] It should be noted that the slide rail 47 extends along the length of the bed board 1. Specifically, the slide rail 47 is disposed on the top surface of the base 2, and the slide block 46 is disposed on the lower surface of the bed board 1; or, the slide block 46 is disposed on the top surface of the base 2, and the slide rail 47 is disposed on the lower surface of the bed board 1. The slide block 46 can slide on the slide rail 47 along the extension direction of the slide rail 47, and the slide rail 47 provides guidance for the slide block 46. Through the cooperation between the slide rail 47 and the slide block 46, the bed board 1 can be slidably disposed on the top surface of the base 2 along the length of the bed board 1, and it can also guide the bed board 1 during sliding, improving the stability of the bed board 1 during sliding.

[0046] In some implementations, such as Figure 5 As shown, the support unit 4 includes a second roller assembly 41 located on the base 2, and the lower surface of the bed board 1 is supported on the second roller assembly 41.

[0047] The second roller assembly 41 includes at least one second roller, which is rotatably mounted on the base 2 along its own axis. The outer periphery of the second roller can contact the lower surface of the bed board 1 to support the movement of the bed board 1 on the base 2. Specifically, the second roller assembly 41 may include two second rollers arranged side by side along the width direction of the bed board 1; or the second roller assembly 41 may include a plurality of second rollers arranged along the length direction of the bed board 1, with the second rollers spaced apart.

[0048] The first roller assembly 3 and the second roller assembly 41 clamp the lower part of the bed board 1 between them. One of them actively applies pressure to the bed board 1, pressing the bed board 1 towards the other. At this time, the one of them that does not actively apply pressure plays a role in limiting the bed board 1 in the vertical direction; or, both of them can actively apply pressure to the bed board 1, pressing the bed board 1 towards each other.

[0049] For example, the first roller group 3 includes a first roller. When the first roller group 3 actively applies pressure to the bed board 1, the second roller group 41 does not actively apply upward pressure. Instead, the second roller group 41 passively cooperates with the first roller group 3 to clamp the bed board 1. The receiving groove 11 of the bed board 1 has a first inner wall that contacts the outer periphery of the first roller. The outer periphery of the first roller presses downward against the first inner wall of the receiving groove 11.

[0050] Alternatively, the second roller group 41 includes a second roller. The second roller group 41 actively applies pressure to the bed board 1. At this time, the first roller group 3 does not actively apply downward pressure. The first roller group 3 passively cooperates with the second roller group 41 to clamp the bed board 1, and the outer periphery of the second roller presses upward on the lower surface of the bed board 1.

[0051] Alternatively, both the first roller group 3 and the second roller group 41 actively apply pressure to the bed board 1 and press against the first inner wall of the receiving groove 11 and the lower surface of the bed board 1, respectively.

[0052] In some implementations, such as Figure 6 As shown, the support unit 4 also includes an eccentric transmission structure and a first motor 45. The eccentric transmission structure includes a first rotating shaft 42, a transmission wheel 43, and a second rotating shaft 44. The first rotating shaft 42 is eccentrically mounted on the transmission wheel 43, and the second rotating shaft 44 is located at the center of the transmission wheel 43. The first rotating shaft 42 is connected to the output end of the first motor 45, and the second roller assembly 41 is mounted on the second rotating shaft 44. The second roller assembly 41 is in contact with the lower surface of the bed board 1.

[0053] In this embodiment, the first motor 45 is disposed within the base 2. The second roller assembly 41 actively applies pressure to the bed board 1, and the gap between the second roller assembly 41 and the lower surface of the bed board 1 is adjustable, meaning the pressure applied by the second roller assembly 41 to the bed board 1 is adjustable. The first end of the first rotating shaft 42 is connected to the output end of the first motor 45, and the first motor 45 can drive the first rotating shaft 42 to rotate. The second end of the first rotating shaft 42 is eccentrically connected to the first end face of the transmission wheel 43 along its axial direction, and the first end of the second rotating shaft 44 is connected to the center of the second end face of the transmission wheel 43 along its axial direction. The second roller assembly 41 includes a second roller, which is rotatably sleeved on the second end of the second rotating shaft 44. The rotation of the first motor 45 drives the first rotating shaft 42 to rotate. Since the first rotating shaft 42 is eccentrically connected to the transmission wheel 43, the height of the transmission wheel 43 relative to the first rotating shaft 42 will change during the rotation of the transmission wheel 43 driven by the first rotating shaft 42. The second rotating shaft 44 is connected to the center of the transmission wheel 43. When the height of the transmission wheel 43 changes, the height of the second rotating shaft 44 also changes accordingly, and the height of the second roller mounted on the second rotating shaft 44 also changes accordingly, thereby enabling the adjustment of the gap between the second roller assembly 41 and the lower surface of the bed board 1. It should be noted that the second roller assembly 41 is a follower wheel, which rolls on the lower surface of the bed board 1 as the bed board 1 moves. The first motor 45 does not run continuously. When it is necessary to adjust the gap between the second roller assembly 41 and the lower surface of the bed board 1, the first motor 45 runs, causing the second roller assembly 41 to move closer to or further away from the lower surface of the bed board 1. After the second roller assembly 41 is adjusted to the correct position, the first motor 45 stops running. The adjustable gap between the second roller assembly 41 and the lower surface of the bed board 1 ensures reliable frictional contact between the bed board 1 and the support unit 4, improving the stability of the bed board 1 moving along its length.

[0054] In some implementations, such as Figure 5 As shown, the lower surface of the bed board 1 is provided with a guide groove 13 corresponding to the second roller group 41.

[0055] The guide groove 13 extends along the length of the bed board 1 and is correspondingly arranged with the second roller assembly 41. The second roller can roll within the guide groove 13, and through the cooperation between the second roller assembly 41 and the guide groove 13, it plays a guiding role when the bed board 1 moves along its length. Furthermore, the receiving groove 11 has a first inner wall that contacts the first roller assembly 3, and the first inner wall of the receiving groove 11 can also be provided with a guide groove corresponding to the first roller assembly 3, so that the bed board 1 can move more stably along its length.

[0056] In some implementations, such as Figure 3 As shown, the drive unit 5 includes a second motor, and the transmission mechanism includes a transmission shaft and a drive roller 51. The drive roller 51 is connected to the output end of the second motor through the transmission shaft, and the drive roller 51 is in contact with the lower surface of the bed board 1.

[0057] The second motor is located inside the base 2. A drive roller 51 is located between the base 2 and the bed board 1, with at least a portion of the drive roller 51 located inside the base 2. The first end of the drive shaft is connected to the output end of the second motor, and the drive roller 51 is sleeved on the second end of the drive shaft. The second motor drives the drive shaft to rotate, causing the drive roller 51 on the drive shaft to rotate. The outer circumference of the drive roller 51 can make frictional contact with the lower surface of the bed board 1, thereby moving the bed board 1 along its own length. The drive roller 51 comprises a pair arranged side-by-side along the width direction of the bed board 1.

[0058] In some implementations, such as Figure 3 As shown, the drive unit 5 includes a second motor, and the transmission mechanism includes a meshing gear 52 and a rack 53. The gear 52 is connected to the output end of the second motor, and the rack 53 is disposed on the lower surface of the bed plate 1.

[0059] The second motor is located inside the base 2, and the gear 52 is located between the base 2 and the bed plate 1. The gear 52 is at least partially located inside the base 2, and the rack 53 is disposed on the lower surface of the bed plate 1 and extends along the length direction of the bed plate 1. The gear 52 is sleeved on the output shaft of the second motor. The second motor drives the gear 52 to rotate, which in turn drives the rack 53, which meshes with the gear 52, to move along the extension direction of the rack 53 (the length direction of the bed plate 1). When the rack 53 moves, it can drive the bed plate 1 to move along the extension direction of the rack 53 (the length direction of the bed plate 1).

[0060] In some implementations, such as Figure 1 , Figure 2 and Figure 4 As shown, the bracket 6 extends into the receiving groove 11 from the opening 14. The bed board 1 includes a bed board body. The lower part of the bed board body forms an inwardly flipping support part 12. The lower surface of the support part 12 is supported on the support unit 4. The first roller group 3 presses on the upper surface of the support part 12.

[0061] The top of the support 6 extends from the opening 14 at the bottom of the bed board 1 into the receiving groove 11 of the bed board 1. The portion extending into the receiving groove 11 bends towards both sides of the bed board 1 along its length and is horizontally positioned. The bed board 1 includes a bed board body, and support portions 12 are formed on the lower portions of both sides of the bed board body along its length, bending towards the middle of the bed board body. The support portions 12 are horizontally positioned. The receiving groove 11 is formed between the upper surface of the support portion 12 and the bed board body. The first roller group 3 presses against the upper surface of the support portion 12, and the lower surface of the support portion 12 is supported on the support unit 4.

[0062] In some implementations, such as Figure 7 As shown, the base 2 includes a first part 21 and a second part 22. The support unit 4, the bed board 1, the first roller group 3 and the drive unit 5 are disposed on the first part 21. The first part 21 is supported on the second part 22 by the lifting drive unit 23.

[0063] The base 2 includes a first part 21 and a second part 22, with the first part 21 located above the second part 22. The first part 21 is mounted on the second part 22 via a lifting drive unit 23. The support unit 4, bed board 1, first roller group 3, and drive unit 5 are mounted on the first part 21, thereby enabling the lifting drive unit 23 to drive the support unit 4, bed board 1, first roller group 3, drive unit 5, and the first part 21 to rise and fall relative to the second part 22. The lifting drive unit 23 is an existing structure with a lifting function; exemplarily, the lifting drive unit 23 is a hydraulic lift or a motor-driven worm gear structure.

[0064] This embodiment also provides a medical device, including the examination bed described in the above embodiments.

[0065] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
